Procedures for Tendering
 Outstanding Notes..........
                              If you wish to participate in an exchange offer,
                              you must complete, sign and date the letter of
                              transmittal and fax, mail or deliver the letter
                              of transmittal, together with the outstanding
                              notes, to the exchange agent. If your outstanding
                              notes are held through The Depository Trust
                              Company (DTC), you may deliver your outstanding
                              notes by book-entry transfer.

                              In the alternative, if your outstanding notes are
                              held through the DTC and you wish to participate
                              in an exchange offer, you may do so instead
                              through the automated tender offer program of the
                              DTC. If you tender under this program, you will
                              agree to be bound by the letter of transmittal
                              that we are providing with this prospectus as
                              though you had actually signed the letter of
                              transmittal.

                              By signing or agreeing to be bound by the letter
                              of transmittal, you will represent to us, among
                              other things, that:

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

                              . you have no arrangement or understanding with
                                any person or entity to participate in the
                                distribution of the new notes;

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

                              . if you are a broker-dealer that will receive
                                new notes for your own account in exchange for
                                outstanding notes that were acquired as a
                                result of market-making activities, you will
                                deliver a prospectus, as required by law, in
                                connection with any resale of those new notes;

                              . you are not our "affiliate," as defined in Rule

U.S. Federal Income Tax
 Considerations.............
                              The exchange of outstanding notes for new notes
                              in the exchange offers will not be a taxable
                              event for U.S. federal income tax purposes.

Use of Proceeds.............  We will not receive any cash proceeds from the
                              issuance of the new notes.

Plan of Distribution........  All broker dealers who receive new notes in the
                              exchange offers have a prospectus delivery
                              obligation.

                              Broker-dealers who acquired the outstanding notes
                              as a result of market-making or other trading
                              activities may use this exchange offer
                              prospectus, as supplemented or amended, in

                              noteholders, in order to resell the outstanding
                              notes or the new notes.

Consequences of Failure to
 Exchange Outstanding
 Notes......................  If you do not tender your outstanding notes, you
                              will continue to hold notes subject to the

                              completion of the exchange offers, the liquidity
                              of the market for your outstanding notes could be

                                 About Lyondell

   Lyondell Chemical Company is a global chemical company with leading market
positions in all of its major products, world-scale production capacity and low
cost operations. Lyondell has advantages in the supply of raw materials through
its equity ownerships in its three joint ventures Equistar Chemicals, LP,
LYONDELL-CITGO Refining LP and Lyondell Methanol Company, L.P. Ownership in
these joint ventures enhances Lyondell's operating leverage and, together with
Lyondell's core business of less cyclical chemical products, mitigates the
impact of petrochemical and refining cycles affecting its joint ventures.

   Lyondell's operations are comprised of four businesses: intermediate
chemicals and derivatives, petrochemicals and polymers, refining and methanol.

Intermediate Chemicals and Derivatives (Lyondell Worldwide)

   Lyondell is the world's largest producer of propylene oxide (PO) and a
leading worldwide producer and marketer of PO derivatives, including polyether
polyols, propylene glycol, propylene glycol ethers and butanediol. PO is a key
component in the manufacture of urethanes and nonurethane products. Lyondell is
the world's second largest supplier of toluene diisocyanate (TDI), another key
component of urethanes. End uses for Lyondell's PO and its derivatives include:

  . flexible foam for automotive seating and furniture;

  . antifreeze and coolants;

  . personal care products;

                                       4
<PAGE>


  . coatings, adhesives, sealants and elastomers;

  . resins; and

  . solvents.

   Lyondell is also a major producer of styrene monomer and tertiary butyl
alcohol (TBA), co-products of its proprietary PO technology. Styrene monomer is
used to produce plastics and resins including polystyrene, used in household
goods such as disposable food service items and toys, and expandable
polystyrene, used in foam cups and containers, insulation and packaging.
Lyondell currently utilizes most of its TBA to make methyl tertiary butyl ether
(MTBE), a gasoline blending component used to reduce fuel emissions and enhance
octane. The intermediate chemicals and derivatives business is the only
business conducted through wholly owned Lyondell operations.

Petrochemicals and Polymers (Equistar)

   Lyondell owns 41% of Equistar, which is an integrated, low-cost producer of
petrochemicals and polymers. Equistar is North America's largest producer of
ethylene, propylene and polyethylene and third largest producer of ethylene
oxide. End uses for its products consist of a wide range of consumer and
industrial products including:

  . packaging film;

  . trash bags;

  . plastic bottles;

  . plastic caps and other closures;

  . rigid packaging; and

  . carpet facing and backing.

   Equistar was formed in December 1997 by combining the ethylene, propylene,
aromatics and polymers businesses of Lyondell and Millennium Chemicals Inc.
Equistar was expanded in May 1998 with the addition of the olefins, ethylene
oxide and derivatives businesses of Occidental Chemical Corporation. Dan Smith,
the chief executive officer of Lyondell, also serves as the chief executive
officer of Equistar.

Refining

   Lyondell owns 58.75% of LYONDELL-CITGO Refining, which owns and operates
North America's largest extra heavy crude oil refinery, processing low cost
17(degrees) API crude oil. LYONDELL-CITGO Refining processes large volumes of
this extra heavy crude oil into premium petroleum products including:

  . gasoline;

  . low sulfur diesel;

  . jet fuel;

  . aromatics;

  . lube oils; and

  . other refined products.

                                       5
<PAGE>


   LYONDELL-CITGO Refining has a long-term crude oil supply agreement with
Petroleos de Venezuela, S.A. (PDVSA), the national oil company of Venezuela.
This agreement helps to stabilize earnings and cash flow through an
advantageous pricing formula. LYONDELL-CITGO Refining was formed in 1993 as a
joint venture with CITGO Petroleum Corporation, an indirect wholly owned
subsidiary of PDVSA.

Methanol (Lyondell Methanol)

   Lyondell owns 75% of Lyondell Methanol, the third largest producer of
methanol in the United States. Lyondell Methanol was formed in December 1996 by
Lyondell and MCN Investment Corporation, a producer of natural gas, the primary
raw material for methanol.

Refinancing of Credit Facility

   In May 1999, Lyondell completed a partial refinancing of the debt under its
credit facility. The refinancing reduced consolidated debt by approximately
$630 million and eliminated substantially all debt maturities through year end
2000 by refinancing with longer-term debt. The refinancing consisted of:

  . the issuance of the outstanding notes for gross proceeds of $2.4 billion;

  . the borrowing of an additional $1 billion under two new term loans under
    the credit facility; and

  . the issuance of 40.25 million shares of Lyondell common stock for gross
    proceeds of $765 million.

                              Lyondell's Strategy

   Lyondell's mission is to maximize total return to its stockholders and
increase cash flow through growth, improved profitability and reduced earnings
volatility.

   Lyondell has been a leader in the ongoing restructuring of the chemical
industry, taking a series of steps to reposition its business portfolio over
the past several years. The following is a list of major actions Lyondell has
taken to fulfill this strategy:

<TABLE>
   <C>  <C> <S>
   1993  -- Formation of LYONDELL-CITGO Refining
   1995  -- Acquisition of Alathon(TM) high density polyethylene business
   1996  -- Formation of Lyondell Methanol
   1997  -- Completion of $1.1 billion LYONDELL-CITGO Refining upgrade project
   1997  -- Creation of Equistar
   1998  -- Expansion of Equistar with the addition of the Occidental assets
   1998  -- Acquisition of ARCO Chemical Company
</TABLE>

   Lyondell will continue to identify and evaluate opportunities for strategic
business combinations, including partnership arrangements such as Equistar and
LYONDELL-CITGO Refining, as a means to provide profitable growth and further
enhance Lyondell's competitive positions. Lyondell actively seeks opportunities
to maximize efficiency or value through various transactions, including the
purchase or sale of assets, contractual arrangements or joint ventures. To the
extent permitted under the terms of Lyondell's credit facility and other debt
agreements, some of these transactions may be financed by additional borrowings
or by the issuance of Lyondell common stock.

Building on Leading Market Positions and Technologies to Achieve Profitable
Growth

   Lyondell intends to build on its leading market positions and technologies
to achieve consistent profitable growth. Today, Lyondell and Equistar hold
leading market positions in the majority of their primary products, as shown
below.

</TABLE>

   Lyondell intends to increase sales by creating new markets for its products
through focused technological innovation and the development of higher value
products that create additional uses for Lyondell's primary products. To
achieve this goal, Lyondell is undertaking the following initiatives:

  . participating in anticipated global demand growth in urethanes and
    performance chemicals by using Lyondell's strengths in technology,
    manufacturing, marketing and access to raw materials;

  . taking advantage of additional opportunities derived from Equistar's
    North American market leadership and low cost position in ethylene,
    propylene and polyethylene;

                                       8
<PAGE>


  . strategically expanding Equistar's polymers technology and capacity by
    focusing on higher value products with large market demand potential,
    such as medium and high molecular weight high density polyethylene; and

  . continuing to exploit LYONDELL-CITGO Refining's $1.1 billion refinery
    upgrade by increasing the total processing volume of extra heavy, low
    cost crude oil and producing a higher percentage of higher value
    products. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Results of Operations--First Quarter
    1999 Compared to Fourth Quarter 1998--Refining."

Improving Profitability and Reducing Earnings Volatility

   Lyondell's current business portfolio is strategically positioned to provide
opportunities to improve profitability and reduce earnings cyclicality. In
addition, Lyondell intends to continue its ongoing cost reduction initiatives
to maximize efficiency of its operations.

   Lyondell continues to integrate its businesses:

  . by capitalizing on its advantages in the supply of raw materials between
    Lyondell and Equistar and Equistar and LYONDELL-CITGO Refining in order
    to capture profit margins across a wide range of products and to improve
    stability of production volumes and earnings throughout Lyondell; and

  . through increasing Equistar product sales and improving its marketing
    efforts using the global expertise and market presence of Lyondell.

   Lyondell continues its efforts to reduce costs:

  . by completing the cost reduction programs in place at Lyondell, Equistar
    and LYONDELL-CITGO Refining;

  . through realizing identified cost savings and revenue enhancements across
    Lyondell's business portfolio by optimizing manufacturing operations,
    using more efficient purchase and distribution practices and reducing
    overhead and staffing; and

  . by maximizing value from the strategic flexibility and optimization
    potential inherent in Equistar's large number of plant sites, raw
    material flexibility and broad polymers product slate.

Debt Reduction and Refinancing Initiatives

   Lyondell significantly increased its borrowed funds in 1998 to acquire
Lyondell Worldwide. The decision to take advantage of this acquisition
opportunity did not alter management's view of an optimal long-term capital
structure which calls for a lower debt-to-equity ratio and an investment grade
debt rating. Lyondell is looking to the cash flow of its businesses, potential
joint ventures involving strategic assets, new equity capital, working capital
initiatives, potential asset sales, refinancing plans and other cash generating
opportunities to achieve this goal.

   Management believes that Lyondell is well positioned through its leading
market positions, world-scale production capacity and low cost operations to
continue to satisfy its ongoing cash requirements through its share of cash
distributions from both Equistar and LYONDELL-CITGO Refining and cash flow from
its intermediate chemicals and derivatives business. This positioning should
also generate significant additional cash flow when prices for some of
Lyondell's cyclical products emerge from their current troughs.

                              unsubordinated debt of each guarantor. The
                              guarantees of the Senior Subordinated Notes will
                              be general obligations of each guarantor and will
                              rank junior to all existing and future
                              unsubordinated debt of each guarantor, including
                              the guarantees of the Senior Secured Notes.

Security....................  The Senior Secured Notes will be secured by a
                              lien equally and ratably with all debt
                              outstanding under our credit facility and, with
                              respect to some of our manufacturing plants, some
                              Lyondell Worldwide bonds as well. The liens will
                              constitute first-priority liens, subject to
                              exceptions and permitted liens, on the following:

                              . Lyondell's and Lyondell Worldwide's personal
                                property;

                              . substantially all the stock of the domestic
                                subsidiaries directly owned by Lyondell and
                                Lyondell Worldwide;

                              . 65% of the stock of foreign subsidiaries
                                directly owned by Lyondell and Lyondell
                                Worldwide;

                              . the rights of some of Lyondell's subsidiaries
                                to receive distributions from Lyondell's
                                existing joint ventures in which they own
                                equity interests; and

                              . mortgages on Lyondell Worldwide's facilities
                                located in Bayport, Texas, Channelview, Texas
                                and Lake Charles, Louisiana.

                              The Senior Secured Notes could become unsecured.
                              Any lien for the benefit of the holders of the
                              Senior Secured Notes will be automatically
                              released, without the consent of the holders,
                              upon a release of that lien under the terms of
                              the security documents or if the release is
                              approved by the requisite lenders under our
                              credit facility. In addition, the collateral
                              agent and Lyondell may amend the provisions of
                              the security documents with the consent of the
                              requisite lenders and without the consent of the
                              holders of the Senior Secured Notes. The lenders
                              under the existing credit facility will have the
                              sole ability to control remedies with respect to
                              the collateral, including any sale or liquidation
                              after acceleration of the new notes or the debt
                              under the credit facility.

Ranking.....................  The Senior Secured Notes will rank equally with
                              all our existing and future unsecured senior debt
                              and before all such debt to the extent of the
                              value of the collateral available to the holders
                              of the Senior Secured Notes. This collateral is
                              shared by the holders of the new notes on a
                              ratable basis with the holders of Lyondell's
                              other senior secured debt, including the debt
                              under the credit facility and some debt of
                              Lyondell Worldwide.

                              The Senior Subordinated Notes will rank junior to
                              all our existing and future unsubordinated debt,
                              including the Senior Secured Notes, the debt
                              under our credit facility and some debt of
                              Lyondell Worldwide.

                              The new notes will also effectively rank junior
                              to all liabilities of our subsidiaries that have
                              not guaranteed the new notes and all liabilities
                              of our joint ventures.

                                       11
<PAGE>


                              The new notes will rank equal in right of payment
                              with any outstanding notes that are not
                              exchanged.

                              At May 31, 1999:

                              . Lyondell and the guarantors had outstanding
                                approximately $5.8 billion of unsubordinated
                                debt that was secured, including the Senior
                                Secured Notes; and

                              . Lyondell's joint ventures, which have not
                                guaranteed the new notes, had approximately
                                $4.0 billion of outstanding liabilities,
                                including trade payables, that are effectively
                                senior to the new notes.

Restrictive Covenants.......  The new notes will be issued under the same
                              indentures as the outstanding notes. The
                              indentures contain restrictive covenants for your
                              benefit that restrict our ability, and the
                              ability of our subsidiaries, to:

                              . incur additional debt or issue subsidiary
                                preferred stock;

                              . increase dividends on our capital stock;

                              . redeem or repurchase capital stock or
                                repurchase subordinated debt;

                              . engage in transactions with affiliates, except
                                on an arms-length basis;

                              . create liens or engage in sale and leaseback
                                transactions;

                              . make some types of investments and sell assets;
                                and

                              . consolidate or merge with, or sell
                                substantially all our assets to, another
                                person.

                              Some of these covenants will no longer apply if
                              the new notes are rated "BBB-" by Standard &
                              Poor's or "Baa3" by Moody's, even if the new
                              notes are subsequently downgraded to a lower
                              rating.

Form of New Notes...........  The new notes will be represented by one or more
                              permanent global securities deposited with the
                              DTC. You will not receive certificates for your
                              new notes unless one of the events described
                              under the heading "Book-Entry; Delivery and
                              Form--Certificated Notes" on page 124 occurs.
                              Instead, beneficial ownership interests in the
                              new notes will be shown on the book-entry records
                              maintained by the DTC. Transfers of beneficial
                              ownership of the new notes will be effected only
                              through the book-entry records maintained by the
                              DTC.

Liquidated Damages..........  If we fail to complete the exchange offers as
                              required by the registration rights agreement, we
                              will be obligated to pay liquidated damages to
                              holders of the outstanding notes as described on
                              page 123.

Use of Proceeds.............  We will not receive any cash proceeds from the
                              issuance of the new notes.

                                  Risk Factors

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

Risk Factors Relating to the New Notes and the Exchange Offers

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

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

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

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

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

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

  . your ability to sell your new notes; or

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

   Future trading prices of the new notes will depend on many factors,
including:

  . prevailing interest rates;

  . our operating results;

  . ratings of the new notes; and

  . the market for similar securities.

   The initial purchasers of the outstanding notes have advised us that they
presently intend to make a market in the new notes after completion of the
exchange offers. However, the initial purchasers do not have any obligation to
do so, and they may discontinue any market-making activities at any time
without any notice.

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

Risk Factors Relating to Lyondell's Debt

Our balance sheet is highly leveraged; in order to fulfill our debt repayment
obligations, we may need to refinance our debt, delay acquisitions or capital
expenditures, or take other action to raise cash or reduce expenses.

   At May 31, 1999, Lyondell had $6.3 billion of consolidated debt, which
amounted to approximately 82 percent of its total capitalization. Lyondell's
consolidated debt amounts do not include $3.1 billion in joint venture debt,
$713 million of which is Equistar debt for which Lyondell remains contingently
liable.

                                       14
<PAGE>

   Lyondell's ability to pay or to refinance its debt will depend on future
operating performance, which will be affected by general economic, financial,
competitive, legislative, regulatory, business and other factors. Many of these
factors are beyond Lyondell's control. Lyondell anticipates that its operating
cash flow, together with money Lyondell can borrow under its credit facility,
will be sufficient to meet anticipated future operating expenses and capital
expenditures. However, if future operating cash flows are less than currently
anticipated, Lyondell may be forced to:

  . reduce or delay capital acquisitions or capital expenditures;

  . sell assets; or

  . reduce operating expenses.

   Approximately $240 million of Lyondell's remaining outstanding debt will be
required to be repaid by December 31, 2000. Lyondell expects that most of this
debt will be repaid using cash from operations. The remaining debt is expected
to be repaid from proceeds of capital markets issuances, asset sales and/or
joint venture transactions. In addition, Lyondell's amended credit facility
requires Lyondell to issue up to approximately $470 million of additional
subordinated notes (or more junior securities) by June 2002, unless specified
financial tests are satisfied. This $470 million requirement will be reduced by
$2 for every $1 of common stock issued in the future and will be eliminated if
Lyondell achieves either:

  . a total debt to adjusted EBITDA ratio, as defined in the credit facility,
    of 3.0 to 1.0; or

  . a rating for its senior secured debt of BB by Standard & Poor's and Ba2
    by Moody's.

Lyondell cannot assure you that it will be able to sell these securities on
satisfactory terms, if at all.

Our debt agreements may restrict our ability to take some actions regardless of
whether these actions may be beneficial to holders of the new notes, our
stockholders or Lyondell.

   Our Indentures

   The indentures governing the new notes contain covenants that limit
Lyondell's ability to engage in some types of transactions. Among other things,
these covenants limit Lyondell's and Lyondell's subsidiaries' ability to:

  . incur additional debt or issue subsidiary preferred stock;

  . increase dividends on its capital stock;

  . redeem or repurchase capital stock or repurchase subordinated debt;

  . engage in transactions with affiliates, except on an arms-length basis;

  . create liens or engage in sale and leaseback transactions;

  . make some types of investments and sell assets; and

  . consolidate or merge with, or sell substantially all its assets to,
    another person.

   Our credit facility

   Lyondell's credit facility also contains restrictive covenants and prohibits
Lyondell from prepaying other debt, including the new notes, until some loans
under the credit facility are repaid in full and Lyondell's senior unsecured
debt is rated investment grade. The credit facility also requires Lyondell to
maintain specified financial ratios and satisfy financial condition tests.
Lyondell's ability to meet those financial ratios and tests can be affected by
events beyond its control, and Lyondell cannot assure you that it will be able
to satisfy those ratios and tests. The credit facility covenants also limit
Lyondell's ability to:

  . increase dividends on its capital stock;

  . make some types of investments; and

  . allow its subsidiaries to incur some types and amounts of debt.

                                       15
<PAGE>

   A breach of any of these provisions could permit the lenders to accelerate
the debt under the credit facility to be immediately due and payable and to
terminate all commitments to extend further credit. If Lyondell were unable to
repay this debt, the lenders could proceed against the collateral granted to
them as security. Lyondell has pledged a substantial portion of its assets as
security for obligations under the credit facility and the Senior Secured
Notes. Lyondell cannot assure you that, if its lenders accelerate the repayment
of borrowings under the credit facility, Lyondell will have sufficient assets
to repay the new notes.

Most of the covenants under the new notes do not apply to our joint ventures;
our joint ventures could increase their debt leverage, default on their debt
obligations or take other action limiting their ability to pay distributions to
Lyondell for which you will have no recourse.

   Lyondell conducts a substantial amount of its operations through its joint
ventures Equistar, LYONDELL-CITGO Refining and Lyondell Methanol. None of these
joint ventures is a "subsidiary" or a "restricted subsidiary" of Lyondell, as
those terms are defined in the indentures. Therefore, the covenants described
above do not apply to the joint ventures in which Lyondell participates.

   As a result, holders of the new notes will have no recourse if Equistar,
LYONDELL-CITGO Refining or Lyondell Methanol substantially increases its debt
leverage. The indentures obligate Lyondell to use its best efforts to ensure
that its joint ventures do not agree to restrictions on their ability to pay
dividends to Lyondell, but that obligation is modified by significant
exceptions. For more information on these exceptions, you should read the
section called "Description of New Notes--Restrictive Covenants--Dividend and
Other Payment Restrictions Affecting Subsidiaries and Joint Ventures."
Equistar, LYONDELL-CITGO Refining and Lyondell Methanol could enter into
agreements that would restrict their ability to pay dividends or make other
distributions to Lyondell despite Lyondell's best efforts to the contrary.
Additionally, under applicable state law, Lyondell's joint ventures may be
limited in amounts that they are permitted to pay as distributions on their
equity interests. Any restriction on dividends from Lyondell's joint ventures
could have a material adverse effect on Lyondell.

   Moreover, a default on debt obligations by a joint venture that is not a
"restricted subsidiary" would not give rise to a default under the indentures
governing the new notes. This is the case even though creditors of the
defaulting joint venture would have remedies against the joint venture. As a
result, holders of the new notes will have no recourse if any of these joint
ventures defaults on any of its debt.

   A default by any of Lyondell's joint ventures under any of its material debt
instruments would give rise to a default under the credit facility. A default
by any joint venture on its debt could also result in a dividend blockage,
which could have a material adverse effect on Lyondell.

The new notes are subordinated to debt of our subsidiaries and joint ventures;
the Senior Subordinated Notes are subordinated to Lyondell's senior debt.

   Subsidiary and joint venture liabilities

   None of Lyondell's joint ventures have guaranteed the new notes. Lyondell's
subsidiaries Lyondell Worldwide and Lyondell Nederland are guarantors of the
new notes and are guarantors under the credit facility. No other subsidiaries
of Lyondell will guarantee the new notes. As a result, the new notes are not
debt of Lyondell's joint ventures or subsidiaries, other than Lyondell
Worldwide and Lyondell Nederland. Holders of the debt and other liabilities of
Lyondell's joint ventures and other subsidiaries will effectively be senior to
claims against those entities by holders of the new notes. At May 31, 1999,
these joint ventures had $4.0 billion of outstanding liabilities, including
trade payables.

                                       16
<PAGE>

   Subordination provisions of the Senior Subordinated Notes

   The Senior Subordinated Notes rank junior to all existing and future senior
debt of Lyondell and the guarantors. At May 31, 1999, Lyondell and the
guarantors had approximately $5.8 billion of senior debt, substantially all of
which was secured.

   As a result of this subordination, if either:

  . Lyondell is insolvent or enters into bankruptcy or a similar proceeding;

  . Lyondell fails to make a payment when due on senior debt; or

  . any senior debt is accelerated;

then the holders of this senior debt must be paid in full before the holders
of the Senior Subordinated Notes may be paid.

   In addition, Lyondell cannot make any cash payments to holders of Senior
Subordinated Notes if it has failed to make payments to holders of designated
senior debt. Under some circumstances, Lyondell cannot make any payments to
holders of Senior Subordinated Notes for a period of up to 179 days if
Lyondell has defaulted on covenants under designated senior debt but there has
been no payment default or acceleration.

   Additional Pari Passu Debt

   If Lyondell incurs any additional debt that ranks equally with the new
notes, the holders of that debt will be entitled to share ratably with the
holders of the new notes in any proceeds distributed in connection with any
insolvency, liquidation, reorganization, dissolution or other winding-up of
Lyondell. This may have the effect of reducing the amount of cash repaid to
holders of the new notes.

Lyondell may not be able to repurchase your new notes upon a change of
control.

   Upon the occurrence of some change of control events described in the
indentures, you may require Lyondell to purchase your new notes at 101% of
their principal amount, plus accrued interest. Lyondell may not have the
financial resources to purchase your new notes, particularly if a change of
control event triggers a similar repurchase requirement for, or results in the
acceleration of, other debt. The credit facility provides that some change of
control events will constitute a default under the credit facility and could
result in the acceleration of the maturity of all debt under the credit
facility. Future debt may also contain similar provisions.

Holders of the Senior Secured Notes may not be able to fully realize the value
of their liens; in such case, holders of the Senior Secured Notes will have an
unsecured claim against Lyondell to the extent that amounts due on the Senior
Secured Notes exceed the proceeds from the sale of the secured assets.

   The security for the benefit of the holders of the Senior Secured Notes can
   be released without their consent.

   The liens for the benefit of the Senior Secured Notes may be released
without any vote or consent by the holders of the Senior Secured Notes under
the following guidelines:

  . the security documents generally provide for an automatic release of all
    liens on any asset that is disposed of in compliance with the provisions
    of the security documents;

  . any lien can be released if approved by the requisite number of lenders
    under our credit facility;

  . the collateral agent and Lyondell may amend the provisions of the
    security documents with the consent of the requisite number of lenders
    under our credit facility and without the consent of the holders of any
    of the Senior Secured Notes; and

  . the lenders under our credit facility will have the sole ability to
    control remedies with respect to the collateral, including the sale or
    liquidation of the collateral after acceleration of the new notes or the
    debt under the credit facility.

                                      17
<PAGE>

As a result, Lyondell cannot assure you that the Senior Secured Notes will
continue to be secured by a substantial portion of Lyondell's assets. Holders
of the Senior Secured Notes will have no recourse if the lenders under
Lyondell's credit facility approve the release of any or all the collateral.
This is the case even if that release adversely affects any rating of the
Senior Secured Notes.

   The collateral may not be valuable enough to satisfy all the obligations
secured by the collateral.

   Lyondell will secure its obligations under the Senior Secured Notes by the
pledge of some of its and Lyondell Worldwide's assets. This pledge is also for
the benefit of the lenders under the credit facility and the holders of
Lyondell Worldwide's outstanding debentures.

   The security documents and the indentures allow Lyondell to apply the
proceeds of any sale of assets, including the collateral and excluding sales
after acceleration of the credit facility, to repay debt under the credit
facility and Lyondell Chemical Worldwide's 9.9% Debentures due 2000 before
repaying amounts owed under the Senior Secured Notes.

   The value of the pledged assets in the event of a liquidation will depend
upon numerous factors, including market and economic conditions and the
availability of buyers. No independent appraisals of the pledged property have
been prepared in connection with the sale of the outstanding notes or the
exchange offers. Accordingly, Lyondell cannot assure you that the proceeds of
any sale of the pledged assets following an acceleration of the Senior Secured
Notes to maturity would be sufficient to satisfy, or would not be
substantially less than, amounts due on the Senior Secured Notes and the other
debt secured thereby. If the proceeds of any sale of the pledged assets were
not sufficient to repay all amounts due on any Senior Secured Notes, the
holders of Senior Secured Notes would have only an unsecured claim against the
remaining assets of Lyondell for the remainder of the amounts due.

   By their nature, some or all of the pledged assets will be illiquid and may
have no readily ascertainable market value. Likewise, Lyondell cannot assure
holders of Senior Secured Notes that the pledged assets will be saleable. If
the pledged assets are saleable, there may be substantial delays in connection
with a liquidation. To the extent that liens, rights and easements granted to
third parties encumber assets located on property owned by Lyondell or
constitute subordinate liens on the pledged assets, third parties may exercise
rights and remedies with respect to the property subject to these
encumbrances, including rights to require marshaling of assets. These rights
of third parties could adversely affect the value of the subject pledged
assets and the ability of the collateral agent to realize or foreclose on the
subject pledged assets.

   Bankruptcy laws may limit your ability to realize value from the
collateral.

   If Lyondell defaults under the indentures for the Senior Secured Notes, the
collateral agent's right to repossess and dispose of the pledged assets is
likely to be significantly impaired if a bankruptcy case is commenced by or
against Lyondell before the collateral agent repossesses and disposes of the
pledged assets. Under the bankruptcy code, a secured creditor is prohibited
from repossessing its security from a debtor in a bankruptcy case, or from
disposing of security repossessed from that debtor, without approval of the
bankruptcy court. Moreover, the bankruptcy code permits the debtor in default
to continue to retain and use the collateral so long as the secured creditor
receives "adequate protection" by court order.

   The meaning of the term "adequate protection" may vary according to
circumstances. In general, it is intended to protect the value of a secured
creditor's interest in the collateral and may include cash payments or the
granting of additional security for any decrease in the value of the
collateral as a result of the stay of repossession or the disposition or use
of the collateral by the debtor during the bankruptcy case. Generally,
adequate protection payments are not required to be paid by a debtor to a
secured creditor unless the bankruptcy court determines that the value of the
secured creditor's interest in the collateral is declining during

                                      18
<PAGE>

the course of the bankruptcy case. Due to the lack of a precise definition for
the term "adequate protection" and the broad discretionary powers of a
bankruptcy court, it is impossible to predict:

  . how long payments under the Senior Secured Notes could be delayed
    following the beginning of the bankruptcy case;

  . whether or when the collateral agent could repossess or dispose of the
    pledged assets; or

  . whether or to what extent holders of the Senior Secured Notes would be
    compensated for any delay in payment or loss of value of the pledged
    assets through the requirement of "adequate protection."

   The collateral is subject to casualty risks and no mortgage title insurance
has been obtained.

   Lyondell is obligated under the security documents at all times to properly
insure the pledged assets against loss or damage by fire or other hazards to
the extent that these assets are usually insured by corporations operating
assets of a similar nature in the same or similar localities. There are,
however, some types of losses which may be either uninsurable or not
economically insurable. Further, the insurance proceeds may not compensate
Lyondell fully for its losses. In the event there is a total or partial loss of
any of the pledged assets, the proceeds received by Lyondell may not be
sufficient to satisfy all the secured obligations, including the Senior Secured
Notes.

   In the event of a total or partial loss to any of the mortgaged facilities,
some items of equipment may not be easily replaced because they are
sufficiently large or customized that replacement units generally are not
readily available. Accordingly, notwithstanding any insurance coverage, the
large size of some of Lyondell's equipment and the extended period needed to
manufacture replacement units could cause significant delays in replacement.

   Additionally, Lyondell is not required under the security documents to
purchase any title insurance insuring the collateral agent's lien on the
mortgaged properties. If a loss occurs from any mortgaged property because of a
title defect, Lyondell might not be able to replace the property with
collateral of equal value.

Fraudulent transfer statutes may limit your rights as a note holder; a court
could invalidate our obligations under the new notes or the liens or
subordinate your rights as a note holder to the rights of other creditors.

   The incurrence by Lyondell of debt, including the new notes, to refinance
the debt incurred under the credit facility to acquire Lyondell Worldwide could
be reviewed under relevant federal and state fraudulent transfer laws in a
bankruptcy case or a lawsuit by or on behalf of unpaid creditors of Lyondell.
The collateral for the Senior Secured Notes includes mortgages on a substantial
portion of the domestic operating assets of Lyondell Worldwide. These assets
are not burdened by any liens and are available for claims of Lyondell
Worldwide's creditors before the claims of Lyondell's creditors. Creditors of
Lyondell Worldwide might claim that the granting of the liens on these assets
is a fraudulent transfer under federal or state laws.

   Federal or state fraudulent transfer laws permit a court to do all of the
following:

  . avoid all or a portion of Lyondell's obligations to holders of the new
    notes;

  . subordinate Lyondell's obligations to holders of the new notes to
    Lyondell's other existing and future debt, thereby entitling other
    creditors to be paid in full before any payment is made on the new notes;
    or

  . take other action detrimental to holders of the new notes, including, in
    some circumstances, invalidating the new notes or the liens securing the
    Senior Secured Notes.

                                       19
<PAGE>

If a court were to take any of these actions, holders of the new notes might
not ever be repaid.

   Under federal and state fraudulent transfer laws, to take any of those
actions, courts will typically need to find that, at the time the new notes
were issued, Lyondell either:

  . issued the new notes with the intent of hindering, delaying or defrauding
    current or future creditors; or

  . received less than fair consideration or reasonably equivalent value for
    incurring the debt represented by the new notes and:

    (1) was insolvent or was rendered insolvent by reason of the issuance
        of the new notes;

    (2) was engaged, or about to engage, in a business or transaction for
        which Lyondell's assets were unreasonably small; or

    (3) intended to incur, or believed or should have believed it would
        incur, debts beyond its ability to pay as the debts mature.

All of the terms used above are defined in or interpreted under the applicable
fraudulent transfer laws.

   Different jurisdictions define "insolvency" differently. However, Lyondell
generally would be considered insolvent at the time it incurred the debt
constituting the new notes if either:

  . the fair market value, or fair saleable value, of its assets is less than
    the amount required to pay its total existing debts and liabilities,
    including the probable liability on contingent liabilities, as they
    become absolute or matured; or

  . Lyondell was incurring debts beyond its ability to pay as the debts
    mature.

   Lyondell cannot assure holders of the new notes:

  . what standard a court would apply to determine if Lyondell was
    "insolvent" on the date it issued the new notes;

  . that a court would not determine that Lyondell was insolvent on the date
    it issued the new notes under either valuation method described above; or

  . that a court would not determine that the payments constituted fraudulent
    transfers on some other legal ground without regard to Lyondell's
    solvency.

Fraudulent transfer statutes may limit your rights under the guarantees; a
court could invalidate the guarantees or subordinate your rights under the
guarantees to the rights of other creditors.

   Our obligations under the new notes are guaranteed by Lyondell Worldwide and
Lyondell Nederland, two of our subsidiaries. The guarantees may be reviewed
under various laws enacted for the protection of creditors. It is possible that
the creditors of a guarantor may challenge a guarantee as a fraudulent transfer
under relevant federal and state laws, by claiming, for example, that the
obligations of the guarantor were incurred for less than reasonably equivalent
value or fair consideration because the guarantee was incurred for the benefit
of Lyondell and only indirectly, if at all, for the benefit of the guarantor.
Under some circumstances, including a finding that a guarantor was insolvent at
the time its guarantee was issued, a court could hold that the obligations of
the guarantors under the guarantees may be voided or are subordinate to other
obligations of the guarantors. In addition, it is possible that the amount for
which a guarantor is liable under a guarantee may be limited. In that case, the
analysis of insolvency described above would generally apply.

   In an attempt to limit the applicability of fraudulent transfer laws, the
indentures limit the amount of the guarantees of Lyondell Worldwide and
Lyondell Nederland to the amount that will result in each guarantee not
constituting a fraudulent transfer or improper corporate distribution. However,
Lyondell cannot assure you as to what standard a court would apply in making a
determination as to what would be the maximum liability of a guarantor.

Risk Factors Relating to Lyondell's Business

The chemical and refining industries are cyclical and volatile; the chemical
industry has experienced alternating periods of tight supply and overcapacity
which affect our results of operations and the market value of the new notes.

   Lyondell's historical operating results reflect the cyclical and volatile
nature of both the chemical and refining industries. Both industries are mature
and capital intensive. Margins for these industries are sensitive to supply and
demand balances, which have historically been cyclical. The chemical industry
historically has experienced alternating periods of tight supply, causing
prices and profit margins to increase. These periods are typically followed by
periods of substantial capacity addition, resulting in oversupply and declining
prices and profit margins.

   Due to the commodity nature of most of Lyondell's products, Lyondell is not
necessarily able to protect its market position by product differentiation or
to pass on cost increases to its customers. Accordingly, increases in raw
materials and other costs do not necessarily correlate with changes in product
prices, either in the direction of the price change or in absolute magnitude.

   Moreover, a number of Lyondell's competitors in various segments of the
chemical industry have announced plans for expansion of plant capacity.
Lyondell cannot assure holders of the new notes that future growth in product
demand will be sufficient to utilize this additional, or even current,
capacity. Excess industry capacity may lower Lyondell's production rates and
margins and its income and cash flow. As a result, Lyondell's earnings
fluctuate significantly.

   External factors beyond Lyondell's control, including:

  . general economic conditions;

  . competitor action;

  . international events and circumstances; and

  . governmental regulation in the United States and abroad

can cause volatility in raw material prices, demand for Lyondell's products,
product prices and volumes, and margins. These factors can also magnify the
impact of economic cycles on Lyondell's business. A number of Lyondell's
products are highly dependent on durable goods markets that are particularly
cyclical, such as the housing and automotive markets. Any events or factors
that adversely affect Lyondell's results of operations may, in turn, also
adversely affect the market value of the new notes.

The chemical industry is highly competitive, with many of our competitors
having greater financial resources than we have; competition may affect our
results of operations and the market value of the new notes.

   The chemical industry is highly competitive. Many of Lyondell's competitors
are larger and have greater financial resources than Lyondell. Among Lyondell's
chemical competitors are some of the world's largest chemical companies,
including:

  . The Dow Chemical Company;

  . Shell Chemical;

  . BASF AG; and

  . Bayer AG.

In the past several years, there have been a number of mergers, acquisitions
and spin-offs in the chemical industry. This restructuring activity may result
in fewer but more competitive producers with greater financial resources than
Lyondell.

                                       21
<PAGE>

  Competition within the chemical industry is affected by a variety of factors,
including:

  . product price;

  . reliability of product supply;

  . technical support;

  . customer service;

  . product quality; and

  . availability of potential substitute materials.

Changes in the competitive environment could have a material adverse effect on
the business and operations of Lyondell. These changes could include:

  . the emergence of new competitors;

  . the rate of capacity additions by competitors;

  . the intensification of price competition in Lyondell's markets;

  . the introduction of new or substitute products by competitors;

  . technological innovations by competitors; and

  . new environmental laws and regulatory requirements.

We may encounter difficulties in integrating recently acquired and combined
operations which may affect our results of operations and the market value of
the new notes.

   Lyondell acquired Lyondell Worldwide in July 1998. Lyondell combined its
petrochemicals and polymers business with the business contributed by
Millennium Chemicals Inc. to form Equistar in December 1997. Equistar was
expanded by the addition of businesses previously held by Occidental Petroleum
Corporation in May 1998. The processes of integrating the operations of
Lyondell Worldwide with Lyondell and integrating the operations of Equistar are
not complete.

   As is the case with any integration of major businesses that previously
operated independently, the integration processes for Lyondell Worldwide and
for Equistar require the dedication of significant management and operational
resources. The difficulties of combining operations may be magnified by:

  . coordinating geographically separate organizations;

  . integrating personnel with disparate business backgrounds; and

  . combining different transaction processing and financial reporting
    systems and processes and corporate cultures.

   Lyondell's integration process could cause an interruption of or a loss of
momentum in business activities. In addition, Lyondell may suffer a loss of key
employees, customers or supplies, loss of revenues, increases in costs or other
difficulties, some of which may not have been foreseen. Lyondell may not be
able to realize the operating efficiencies, cost savings and other benefits
that are sought from these transactions. Difficulties encountered in the
integration processes could have a material adverse effect on the business and
operations of Lyondell.

Lyondell and Equistar actively pursue acquisitions, dispositions and joint
ventures which may affect our results of operations and the market price of the
new notes.

   Lyondell and Equistar both actively seek opportunities to maximize
efficiency and value through various transactions, including purchases or sales
of assets or contractual arrangements or joint ventures. These transactions
generally are intended to result in the realization of savings, the creation of
efficiencies or the generation of cash to reduce debt. To the extent permitted
under Lyondell's and Equistar's credit facilities and other debt agreements,
these transactions may be financed by additional borrowings by Lyondell or
Equistar or by the issuance of common stock of Lyondell.

                                       22
<PAGE>

   These transactions may also affect the results of operations of Lyondell or
Equistar in the short term due to the costs associated with these transactions.
However, they are expected to yield longer-term benefits if the anticipated
efficiencies and cost savings of the transactions are realized. Factors such as
those described in the immediately preceding risk factor may make it difficult
or impossible to realize these expected efficiencies and cost savings.

Shared control of joint ventures involving Lyondell may delay decisions or
actions which may affect our results of operations and the market price of the
new notes.

   Lyondell conducts a substantial amount of its operations through its joint
ventures. Lyondell shares control of these joint ventures with unaffiliated
third parties. Lyondell's forecasts and plans for its joint ventures assume
that its joint venture partners will observe their obligations with respect to
the joint ventures. If any of Lyondell's joint venture partners do not observe
their commitments, it is possible that the affected joint venture would not be
able to operate according to its business plans or that Lyondell would be
required to increase its level of commitment in order to give effect to the
business plans.

   As with any joint venture arrangement, differences in views among the joint
venture participants may result in delayed decisions or in failures to agree on
major issues. This could potentially adversely affect the business and
operations of the joint venture and, in turn, the business and operations of
Lyondell.

LYONDELL-CITGO Refining's crude oil supply agreement with PDVSA may limit its
earnings and cash flow and decrease distributions to us; decreased
distributions could affect our results of operations and the market price of
the new notes.

   Substantially all of the crude oil used by LYONDELL-CITGO Refining as a raw
material for its refinery is purchased under the crude supply agreement with
PDVSA. The crude supply agreement was entered into in 1993. Lyondell
experienced the full effects of the crude supply agreement beginning in 1997.
The crude supply agreement incorporates formula prices to be paid by LYONDELL-
CITGO Refining for the crude oil supplied. The formula prices are based on the
market value of a slate of refined products deemed to be produced from each
particular crude oil or raw material less:

  . deemed refining costs adjustable for inflation and energy costs;

  . actual costs, including crude oil transportation costs, import duties and
    taxes; and

  . a deemed margin, which varies according to the grade of crude oil or
    other raw material delivered.

   Deemed margins and deemed costs are adjusted periodically based on inflation
rates for specific deemed cost components. Adjustments to the crude supply
agreement margins track, but are less than, inflation rates. Because deemed
operating costs and the slate of refined products deemed to be produced from a
given barrel of crude oil or other raw material do not necessarily reflect the
actual costs and yields in any period, and also because the market value of the
refined products used in the pricing formula does not necessarily reflect the
actual price received for the refined products, the actual refining margin
earned by LYONDELL-CITGO Refining varies depending on, among other things, the
efficiency of LYONDELL-CITGO Refining's operations.

   Although LYONDELL-CITGO Refining believes that the crude supply agreement
reduces the volatility of its earnings and cash flow, the crude supply
agreement also limits LYONDELL-CITGO Refining's ability to enjoy higher margins
during periods when the market price of crude oil is low relative to the then-
current market prices for refined products. In addition, if the actual yields,
costs or volumes of the LYONDELL-CITGO Refining refinery differ substantially
from those contemplated by the crude supply agreement, the benefits of the
crude supply agreement could be substantially diminished. This could result in
lower earnings and cash flow for LYONDELL-CITGO Refining. Furthermore, there
may be periods during which LYONDELL-CITGO Refining's costs for crude oil under
the crude supply agreement may be higher than crude oil available to LYONDELL-
CITGO Refining from other sources.

                                       23
<PAGE>

The risk of enforcing judgments against non-United States affiliates of a
sovereign nation affects LYONDELL-CITGO Refining's crude oil supply agreement
with PDVSA; inability to enforce the crude supply agreement could result in
decreased distributions from LYONDELL-CITGO Refining to Lyondell that could
affect our results of operations and the market price of the new notes.

   There are risks associated with enforcing the provisions of contracts with
companies such as PDVSA that are non-United States affiliates of a sovereign
nation. It is impossible to predict how governmental policies may change under
the current or any subsequent Venezuelan government. In addition, there are
risks associated with enforcing judgments of United States courts against
companies whose assets are located outside of the United States and whose
management does not reside in the United States.

   All of the crude oil supplied by PDVSA is produced in Venezuela, a country
that has experienced economic difficulties and social and political unrest in
recent years. If the crude supply agreement is modified or terminated, or this
source of crude oil is otherwise interrupted due to production difficulties,
OPEC-mandated supply cuts, political or economic events in Venezuela, or other
factors, LYONDELL-CITGO Refining could experience significantly greater
volatility in its earnings and cash flows.

   Each partner has a right to transfer their interest in LYONDELL-CITGO
Refining to unaffiliated third parties in some circumstances, subject to
reciprocal rights of first refusal. If CITGO were to transfer its interest in
LYONDELL-CITGO Refining to an unaffiliated third party, PDVSA would have an
option to terminate the crude supply agreement. Depending on then-current
market conditions, any breach or termination of the crude supply agreement
could adversely affect LYONDELL-CITGO Refining. LYONDELL-CITGO Refining would
have to purchase all of its crude oil in the open market, which could subject
LYONDELL-CITGO Refining to significant price fluctuations. Alternative crude
oil supplies providing similar margins might not be available for purchase by
LYONDELL-CITGO Refining.

The supply of crude oil to LYONDELL-CITGO Refining has been reduced due to
OPEC-mandated supply cuts; this could result in decreased distributions from
LYONDELL-CITGO Refining to Lyondell and affect our results of operations and
the market price of the new notes.

   In late April 1998, LYONDELL-CITGO Refining received notice from PDVSA of
reduced delivery of crude oil related to announced OPEC production cuts. In
August 1998, LYONDELL-CITGO Refining began receiving reduced deliveries from
PDVSA. Following additional cutbacks announced by OPEC in late March 1999,
LYONDELL-CITGO Refining received notice from PDVSA in May 1999 of further
reductions in its delivery of crude oil under the crude supply agreement.

   Historically, Venezuela has complied with OPEC-mandated supply cuts by
reducing its crude production. Decreased allocations of PDVSA crude oil tend to
reduce LYONDELL-CITGO Refining's pretax income and, accordingly, Lyondell's pro
rata share of LYONDELL-CITGO Refining's income. OPEC-mandated supply cuts are a
force majeure event under the crude supply agreement for which Lyondell has no
contractual remedy.

   While to date LYONDELL-CITGO Refining has been able to obtain alternate
supplies of crude oil, the margin for this crude oil has been less than the
margin for the crude oil purchased under the crude supply agreement. PDVSA may
announce further cutbacks in production and thereby reduce LYONDELL-CITGO
Refining's allocation of crude oil. Lyondell cannot predict whether LYONDELL-
CITGO Refining will be able to continue to obtain adequate alternative supplies
of crude oil, or at what cost it will be able to obtain substitute crude oil.

Hazards associated with chemical manufacturing and petroleum refining may occur
and adversely affect our results of operations and the market price of the new
notes.

   Material operating problems, including but not limited to the events
described below, could occur that might have a material adverse effect on the
productivity and profitability of a particular manufacturing facility, or on
Lyondell as a whole, during and after the period of operational difficulties.
Lyondell's revenues are dependent on the continued operation of its various
production facilities, including the ability to complete

                                       24
<PAGE>

construction projects on a schedule. The usual hazards associated with chemical
manufacturing and refining and the related storage and transportation of raw
materials, products and wastes may occur in Lyondell's operations. These
hazards may include:

  . pipeline leaks and ruptures;

  . explosions;

  . fires;

  . inclement weather and natural disasters;

  . mechanical failure;

  . unscheduled downtime;

  . labor difficulties;

  . transportation interruptions;

  . remediation complications;

  . chemical spills;

  . discharges or releases of toxic or hazardous substances or gases;

  . storage tank leaks; and

  . other environmental risks.

   These hazards may cause personal injury and loss of life, severe damage to
or destruction of property and equipment and environmental damage. These
hazards may also result in suspension of operations and the imposition of civil
or criminal penalties. Furthermore, Lyondell is also subject to present and
future claims with respect to workplace exposure, workers' compensation and
other matters. Lyondell maintains property, business interruption and casualty
insurance which it believes complies with customary industry practices.
However, Lyondell is not fully insured against all potential hazards incident
to its business.

Extensive environmental, health and safety laws and regulations impact our
operations and assets; compliance with these regulations could affect our
results of operations and the market price of the new notes.

   Lyondell's operations and ownership and use of real property are subject to
extensive environmental, health and safety laws and regulations. These laws and
regulations are promulgated by domestic and foreign governments at both the
national and local level. Many of these laws and regulations:

  . impose requirements relating to the clean-up of contamination;

  . impose liability in the event of damage to natural resources; and

  . provide for substantial fines and potential criminal sanctions for
    violations.

   The nature of the chemical and refining industries exposes Lyondell to risks
of liability under these laws and regulations due to the production, refining,
storage, transportation and sale of materials that can cause contamination or
personal injury if released into the environment. In addition, individuals
could seek damages

                                       25
<PAGE>

for alleged personal injury or property damage due to exposure to chemicals at
Lyondell's facilities or to chemicals otherwise owned or controlled by
Lyondell.

   Environmental laws may have a significant effect on:

  . the nature and scope of cleanup of contamination at current and former
    operating facilities;

  . the costs of transportation and storage of raw materials and finished
    products; and

  . the costs of the storage and disposal of wastes.

   Also, Superfund statutes may impose joint and several liability for the
costs of remedial investigations and actions on any company that:

  . generated the waste;

  . arranged for disposal of the waste;

  . transported the waste to the disposal site;

  . selected the disposal site; or

  . presently or formerly owned or operated the disposal site.

All the responsible parties, or any one of them, including Lyondell, may be
required to bear all of the costs of cleanup regardless of fault, legality of
the original disposal or ownership of the disposal site.

   Lyondell expects that the nature of its businesses will continue to subject
Lyondell to increasingly stringent environmental and health and safety laws and
regulations. It is difficult to predict the future interpretation and
development of these laws and regulations or their impact on Lyondell's future
earnings and operations. Lyondell anticipates that compliance will continue to
require increased capital expenditures and operating costs. In particular, the
ultimate effect of the Clean Air Act on Lyondell's operations will depend on
how the law is interpreted and implemented under regulations that are currently
being developed and on additional factors such as the development of
environmental control technologies.

   Lyondell's policy is to accrue costs relating to environmental matters when
it is probable that the costs will be required and can be reasonably estimated.
Estimated costs for future environmental compliance and remediation or other
costs are necessarily imprecise due to factors which include:

  . the continuing evolution of environmental laws and regulatory
    requirements;

  . the availability and application of technology;

  . the identification of presently unknown remediation sites; and

  . the allocation of costs among the responsible parties under applicable
    statutes.

On a quarterly basis, Lyondell evaluates the status of all significant existing
or potential environmental issues, develops or revises estimates of costs to
satisfy known remediation requirements and adjusts its accruals accordingly. As
of May 31, 1999, the reserve was $44 million. Based upon information presently
available, Lyondell does not expect that future environmentally related costs
will have a material adverse effect on its competitive or financial position or
its ongoing results of operations. However, it is not possible to predict
accurately the amount or timing of costs of any future environmental
remediation requirements. Future costs could be material to future quarterly or
annual results of operations.

Pending or future legislative initiatives or litigation may materially
adversely affect our MTBE sales or subject Lyondell to products liability,
which may affect our results of operations and affect the market price of the
new notes.

   MTBE is present in some water supplies in California and other states due to
gasoline leaking from underground storage tanks and recreational water craft.
This has led to public concern that MTBE may

                                       26
<PAGE>

contaminate drinking water supplies and result in a possible health risk. There
have been claims that MTBE travels more rapidly through soil, is more soluble
in water, and is more difficult and more costly to remediate than other
gasoline components.

   Heightened public awareness about MTBE has resulted in state and federal
legislative initiatives that have sought either to rescind the oxygenate
requirement for reformulated gasoline sold in California and other states or
restrict the use of MTBE. In April 1999, the governor of California announced
an intention to eliminate MTBE from gasoline sold in California by December 31,
2002. There is ongoing review of this issue and the ultimate resolution of the
appropriateness of using MTBE could result in a significant reduction in
Lyondell's MTBE sales.

   In addition, Lyondell has a take-or-pay MTBE sales contract with Atlantic
Richfield Company that contributes significant pre-tax margin. If the
legislative initiatives described above are enacted, Atlantic Richfield Company
has indicated that it might attempt to invoke a force majeure provision in the
contract to reduce the quantities of MTBE it purchases under the contract or to
terminate the contract. Lyondell would vigorously dispute either action. The
contract has an initial term expiring December 31, 2002 and provides for
formula-based prices that are currently significantly above spot market prices
for MTBE. A significant reduction in Lyondell's sales under the Atlantic
Richfield Company contract could have a negative impact on Lyondell's results
of operations.

Exchange rate fluctuations, exchange controls, political risks and other risks
relating to foreign operations affect Lyondell's international operations,
which may affect our results of operations and affect the market price of the
new notes.

   A number of risks affect Lyondell's international operations and exports to
foreign markets including:

  . currency exchange rate fluctuations;

  . trade barriers;

  . exchange controls;

  . national and regional labor strikes;

  . political risks;

  . risks of increases in duties and taxes; and

  . changes in laws and policies governing operations of foreign-based
    companies.

   Lyondell uses various types of foreign currency forward, option and swap
contracts to reduce foreign exchange exposures with respect to revenues,
capital commitments and other expenses denominated in foreign currencies.
However, these techniques may not protect Lyondell's reported results against
loss and Lyondell may incur material losses on these hedge contracts. Foreign
income tax rules reducing cash flow available to meet required debt service and
other obligations of Lyondell may apply to earnings of foreign subsidiaries and
intercompany payments.

   A number of Asian and Latin American economies have recently experienced
economic difficulties. Prolonged economic difficulties in the Asian and Latin
American markets could significantly impact worldwide demand and thereby place
downward pressure on margins, which, if material, could in turn have an adverse
effect on the business and operations of Lyondell.

                                       27

Lyondell's quarterly results vary significantly, which could affect the market
price of the notes.

   Lyondell's quarterly results vary significantly depending on various
factors, most of which are beyond Lyondell's control, including:

  . changes in product prices;

  . changes in product demand;

  . changes in raw material costs or supply arrangements;

  . regional business activities, including a lower level of economic
    activity in Europe during the summer;

  . adverse developments in foreign markets;

  . fluctuations in shipments to customers;

  . foreign exchange fluctuations;

  . unanticipated expenses;

  . changes in interest rates; and

  . the scheduling of plant maintenance.

   This prospectus is part of a registration statement we filed with the
Securities and Exchange Commission.

  . You should rely only on the information or representations provided in
    this prospectus.

  . We have not authorized any person to provide information in this
    prospectus other than that provided in this prospectus.

  . We have not authorized anyone to provide you with different information.

                          Forward-Looking Information

   Some of the statements in this prospectus include forward-looking
statements. Although Lyondell believes the expectations reflected in the
forward-looking statements are reasonable, they do involve assumptions, risks,
and uncertainties, and there are no assurances that these expectations will
prove to be correct. The actual results obtained by Lyondell could differ
materially from those anticipated in these forward-looking statements as a
result of factors beyond the control of Lyondell or its joint ventures. These
factors include:

  . the cyclical and highly competitive nature of the chemical and refining
    industries;

  . uncertainties associated with the United States and world-wide economies;

  . current and potential government regulatory actions in the United States
    and other countries;

  . substantial chemical capacity additions resulting in oversupply and
    declining prices and margins;

  . raw materials costs or supply arrangements;

  . Lyondell's ability to implement cost reductions; and

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

   We undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events, or
otherwise. You are cautioned against putting undue reliance on forward-looking
statements or projecting any future results based on these statements or
present or prior earnings levels. All oral or written forward-looking
statements attributable to us or persons acting on our behalf are expressly
qualified in their entirety by these cautionary statements.

                              The Exchange Offers

   We are offering to exchange our outstanding 9 5/8% Senior Secured Notes,
Series A, due 2007, 9 7/8% Senior Secured Notes, Series B, due 2007 and 10
7/8% Senior Subordinated Notes due 2009 for a like kind and principal amount
of our new 9 5/8% Senior Secured Notes, Series A, due 2007, 9 7/8% Senior
Secured Notes, Series B, due 2007 and 10 7/8% Senior Subordinated Notes due
2009. The offers to exchange the outstanding notes are separate, independent
offers. We may extend, delay or terminate one offer without extending,
delaying or terminating the other offers. The description of the exchange
offers contained in this prospectus applies to each of our exchange offers.
However, holders of a particular series of outstanding notes will need to
complete the exchange offer documentation related to that particular series of
notes. Holders who wish to exchange outstanding notes of more than one series
of notes must complete the separate exchange offer documentation related to
each series of notes they wish to tender.

                                      29
<PAGE>

Purpose and Effect of the Exchange Offers

   We are offering the new notes under this prospectus to satisfy our
obligations under the registration rights agreement we entered into with the
initial purchasers of the outstanding notes. Under this agreement, we agreed to
file a registration statement with the SEC relating to our offers to exchange
the outstanding notes for new notes. We also agreed to use our reasonable best
efforts to have the registration statement declared effective within 210 days
after May 17, 1999 and to consummate the exchange offers no later than 30
business days after the registration statement is declared effective.

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

   We will file with the SEC a shelf registration statement to cover resales of
any or all of the series of outstanding notes if any of the following events
occur:

  . an exchange offer is not permitted by applicable law or SEC policy; or

  . any holder of the outstanding notes which are Transfer Restricted
    Securities as defined in the registration rights agreement gives timely
    notice that:

    (1) it is prohibited by law or SEC policy from participating in the
        applicable exchange offer;

    (2) it cannot resell the new notes to the public without delivering a
        prospectus and this prospectus is not appropriate or available for
        those resales by it; or

    (3) it is a broker-dealer that holds outstanding notes acquired
        directly from us or any of our affiliates.

   If we are required to file a shelf registration statement, we will use our
reasonable best efforts to cause the SEC to declare effective the shelf
registration statement within 60 days of the deadline for filing the shelf
registration statement. In addition, each holder will be required to deliver
information to be used in connection with the shelf registration statement in
order to have its outstanding notes included in the shelf registration
statement. We will also use our reasonable best efforts to keep the shelf
registration statement effective for up to two years after May 17, 1999.

   We have the ability to suspend the shelf registration statement for no more
than:

  . 60 days during the first two years after May 17, 1999; and

  . 90 days during any subsequent year

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

   If we fail to comply with deadlines for completion of any of the exchange
offers, we will be required to pay liquidated damages to holders of the series
of outstanding notes so affected. Please read the section captioned
"Registration Rights Agreement" for more details regarding liquidated damages
and Lyondell's obligations under the registration rights agreement.

   To exchange an outstanding note for a freely transferable new note in an
exchange offer, you will be required to make all of the following
representations:

  . any new note you receive will be acquired in the ordinary course of its
    business;

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

  . if you are not a broker-dealer or you are a broker-dealer but will not
    receive new notes for your own account in exchange for outstanding notes,
    that you are not engaged in and do not intend to participate in a
    distribution of the new notes within the meaning of the Securities Act;

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

  . you are not an "affiliate," as defined in Rule 405 of the Securities Act,
    of Lyondell, Lyondell Worldwide or Lyondell Nederland or a broker-dealer
    tendering outstanding notes acquired directly from Lyondell for your own
    account.

Resale of New Notes

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

  . you are not an "affiliate," within the meaning of Rule 405 under the
    Securities Act, of Lyondell, Lyondell Worldwide or Lyondell Nederland;

  . the new note is acquired in the ordinary course of your business; and

  . you do not intend to participate in the distribution of new notes.

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

   If you tender your notes in an exchange offer with the intention of
participating in any manner in a distribution of the new notes, you:

  . cannot rely on these interpretations in "no action letters" by the SEC
    staff; and

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

   Unless an exemption from registration is otherwise available, any security
holder intending to distribute new notes should be covered by an effective
registration statement under the Securities Act containing the selling security
holder's information required by Item 507 or Item 508, as applicable, of
Regulation S-K under the Securities Act. This prospectus may be used for an
offer to resell or a resale or other re-transfer of the new notes of any series
only as specifically described in this prospectus. Failure to comply with the
registration and prospectus delivery requirements by a holder subject to these
requirements could result in that holder incurring liability for which it is
not indemnified by Lyondell. Only broker-dealers that acquired the outstanding
notes as a result of market-making activities or other trading activities may
participate in the exchange offers. Please read the section captioned "Plan of
Distribution" for more details regarding the transfer of the new notes.

Terms of the Exchange Offers

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

   As of the date of this prospectus, $900 million of 9 5/8% Senior Secured
Notes, Series A, due 2007, $1 billion of 9 7/8% Senior Secured Notes, Series B,
due 2007 and $500 million of 10 7/8% Senior Subordinated Notes due 2009 are
outstanding. This prospectus and the applicable letter of transmittal are being
sent to all registered holders of these outstanding notes. There will be no
fixed record date for determining registered holders of outstanding notes
entitled to participate in any of the exchange offers.

   We intend to conduct the exchange offers according to the provisions of the
registration rights agreement, the applicable requirements of the Securities
Act and the Securities Exchange Act of 1934 and the rules and regulations of
the SEC. Outstanding notes that are not tendered for exchange in an exchange
offer will remain outstanding and continue to accrue interest and will be
entitled to the rights and benefits the holders have under the applicable
indenture and the registration rights agreement.

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

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

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

Expiration Date

   Unless sooner terminated, the exchange offers will expire at 5:00 p.m., New
York City time on                , 1999, unless, in our sole discretion, we
extend one or all of the exchange offers.

Extensions, Delay in Acceptance, Termination or Amendment

   We expressly reserve the right, at any time or from time to time to extend
the period of time during which any exchange offer is open. We may extend any
exchange offer independently of the expiration date of the other exchange
offers. During any extension, all outstanding notes previously tendered will
remain subject to the applicable exchange offer, and we may accept them for
exchange. To extend an exchange offer, we will notify the exchange agent orally
or in writing of any extension. We will also make a public announcement of the
extension no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date.

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

  . delay accepting for exchange any outstanding notes;

                                       32
<PAGE>

  . extend any or all of the exchange offers; or

  . terminate any or all of the exchange offers

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

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

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

Conditions to the Exchange Offers

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

  . we will not be required to accept for exchange, or to exchange any new
    notes for, any outstanding notes; and

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

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

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

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

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

   These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time or at various times in our sole
discretion. If we fail at any time to exercise any of these rights, this
failure will not mean that we have waived our rights. Each right will be deemed
an ongoing right that we may assert at any time or at various times. In
addition, we will not accept for exchange any outstanding notes tendered and
will not issue new notes in exchange for any outstanding notes if, at that
time, any stop order has been threatened or is in effect with respect to:

  . the registration statement of which this prospectus is a part; or

                                       33
<PAGE>

  . the qualification of the applicable indenture relating to the notes under
    the Trust Indenture Act of 1939.

Procedures for Tendering

 How to Tender Generally

   Only a registered holder of outstanding notes may tender outstanding notes
in an exchange offer. To tender in an exchange offer, you must either:

  (1) .complete, sign and date the applicable letter of transmittal;

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

    .  mail, fax or deliver the applicable letter of transmittal to the
       exchange agent before the expiration date of the applicable exchange
       offer; and

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

  (2) comply with the automated tender offer program procedures of DTC
      described below.

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

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

   The method of delivery of the outstanding notes, the applicable letter of
transmittal and all other required documents to the exchange agent is at the
holder's election and risk. Except as provided in the applicable letter of
transmittal, delivery of these items will be deemed made only when actually
received or confirmed by the exchange agent. Rather than mail these items, we
recommend that holders use an overnight or hand delivery service. In all cases,
holders should allow sufficient time to ensure delivery to the exchange agent
before the expiration date. Holders should not send the applicable letter of
transmittal or outstanding notes to us. Holders may request their brokers-
dealers, commercial banks, trust companies or other nominees to effect the
above transactions on their behalf.

 Tendering Through DTC's Automated Tender Offer Program

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

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

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

                                       34
<PAGE>

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

  . the agreement may be enforced against the participant.

 How to Tender if You are a Beneficial Owner

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

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

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

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

 Signatures and Signature Guarantees

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

  . a member firm of a registered national securities exchange;

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

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

  . an "eligible guarantor institution" within the meaning of Rule 17Ad-15
    under the Securities Exchange Act of 1934 that is a member of one of the
    recognized signature guarantee programs identified in the applicable
    letter of transmittal

unless the outstanding notes are tendered either:

  . by a registered holder who has not completed the box entitled "Special
    Issuance Instructions" or "Special Delivery Instructions" on the
    applicable letter of transmittal and the new notes are being issued
    directly to the registered holder of the outstanding notes tendered in
    the exchange for those new notes; or

  . for the account of a financial institution that is a participant in one
    of the medallion guarantee programs specified in the applicable letter of
    transmittal.

 When Endorsements or Bond Powers are Needed

   If the applicable letter of transmittal is signed by the registered holder
of the outstanding notes to be tendered and the new notes are to be issued to
the registered holder, then the outstanding notes are not required to be
endorsed and a bond power is not required. In any other case, a holder
tendering outstanding notes must either endorse the outstanding notes to be
tendered or provide a properly completed bond power. The bond power must be
signed by the registered holder as the registered holder's name appears on the
outstanding notes and a financial institution that is a participant in one of
the medallion guarantee programs specified in the applicable letter of
transmittal must guarantee the signature on the bond power.

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

                                       35

 Determinations Under the Exchange Offers

   We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered outstanding notes
and withdrawal of tendered outstanding notes. Our determination will be final
and binding. We reserve the absolute right to reject any and all outstanding
notes not properly tendered or any outstanding notes our acceptance of which
would, in our opinion or the opinion of our counsel, be unlawful. We also
reserve the right to waive any defects, irregularities or conditions of tender
as to particular outstanding notes. Our interpretation of the terms and
conditions of an exchange offer, including the instructions in the applicable
letter of transmittal, will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of outstanding notes
must be cured within the time we will determine. Neither we, the exchange agent
nor any other person will be under any duty to give notification of defects or
irregularities with respect to tenders of outstanding notes, and none of the
aforementioned will incur liability for failure to give notification. Tenders
of outstanding notes will not be deemed made until any defects or
irregularities have been cured or waived. Any outstanding notes received by the
exchange agent that are not properly tendered and the defects or irregularities
of which have not been cured or waived will be returned to the tendering
holder, unless otherwise provided in the applicable letter of transmittal, as
soon as practicable following the expiration date.

 When We Will Issue New Notes

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

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

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

 Return of Outstanding Notes Not Accepted or Exchanged

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

   By signing or agreeing to be bound by the applicable letter of transmittal,
you will represent, among other things, that:

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

  . you have no arrangement or understanding with any person to participate
    in the distribution of the new notes;

  . if you are not a broker-dealer or are a broker-dealer but will not
    receive new notes for your own account in exchange for outstanding notes,
    that you are not engaged in and do not intend to participate in a
    distribution of the new notes;

  . if you are a broker-dealer that will receive new notes for your own
    account in exchange for outstanding notes which were acquired for your

    market-making activities or other trading activities and that you will
    deliver a

<PAGE>

    prospectus, meeting the requirements of the Securities Act, in connection
    with any resale of the new notes; and

  . that you are not an "affiliate," as defined in Rule 405 of the Securities
    Act, of Lyondell, Lyondell Worldwide or Lyondell Nederland or a broker-
    dealer tendering outstanding notes acquired directly from Lyondell for
    your own account.

Book-entry Transfer

   The exchange agent will make a request to establish an account with respect
to each series of the outstanding notes at DTC for purposes of the exchange
offers promptly after the date of this prospectus. Any financial institution
participating in DTC's system may make book-entry delivery of outstanding
notes by causing DTC to transfer the outstanding notes into the exchange
agent's respective account at DTC according to DTC's procedures for transfer.

   Holders whose outstanding notes are not immediately available or who are
unable to deliver confirmation of the book-entry tender of their outstanding
notes into the exchange agent's account at DTC or all other documents required
by the applicable letter of transmittal to the exchange agent on or before the
applicable expiration date must tender their outstanding notes according to
the guaranteed delivery procedures described below.

Guaranteed Delivery Procedures

   If you wish to tender your outstanding notes but your outstanding notes are
not immediately available or you cannot deliver your outstanding notes, the
applicable letter of transmittal or any other required documents to the
exchange agent or comply with the applicable procedures under DTC's automated
tender offer program before the expiration date, you may tender if:

  . the tender is made by or through a financial institution that is a
    participant in one of the medallion guarantee programs specified in the
    applicable letter of transmittal;

  . before the applicable expiration date, the exchange agent receives from
    the eligible guarantor financial institution, either a properly completed
    and duly executed notice of guaranteed delivery or a properly transmitted
    agent's message and notice of guaranteed delivery:

    (1) stating your name and address, the registration number(s) of your
        outstanding notes and the total principal amount of outstanding
        notes tendered;

    (2) stating that the tender is being made; and

    (3) guaranteeing that, within five business days after the expiration
        date, the applicable letter of transmittal or an agent's message in
        lieu thereof, together with the outstanding notes or a book-entry
        confirmation and any other documents required by the applicable
        letter of transmittal, will be deposited by the eligible guarantor
        institution with the exchange agent; and

  . the exchange agent receives the properly completed and executed
    applicable letter of transmittal, as well as all tendered outstanding
    notes in proper form for transfer or a book-entry confirmation and all
    other documents required by the applicable letter of transmittal, within
    five business days after the expiration date.

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

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw your
tender at any time before 5:00 p.m., New York City time, on the expiration
date unless previously accepted for exchange. For a withdrawal to be
effective:

                                      37
<PAGE>

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

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

Any notice of withdrawal must comply with the following requirements:

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

  . identify the outstanding notes to be withdrawn, including the
    registration numbers of the outstanding notes and the total principal
    amount of the outstanding notes;

  . contain the signature of the depositor in the same manner as the original
    signature on the applicable letter of transmittal used to deposit those
    outstanding notes or be accompanied by documents of transfer sufficient
    to permit the trustee for the outstanding notes to register the transfer
    into the name of the depositor withdrawing the tender; and

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

If outstanding notes have been tendered under the procedure for book-entry
transfer described above, any notice of withdrawal must specify the name and
number of the account at DTC to be credited with the withdrawn outstanding
notes and otherwise comply with the procedures of DTC.

   We will determine all questions as to the validity, form, eligibility and
time of receipt of notice of withdrawal. Our determination will be final and
binding on all parties. We will deem any outstanding notes so withdrawn not to
have been validly tendered for exchange for purposes of the exchange offers.

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

Fees and Expenses

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

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

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

  . SEC registration fees;

  . fees and expenses of the exchange agent and trustee;

  . accounting and legal fees and printing costs; and

  . related fees and expenses.

                                      38
<PAGE>

Transfer Taxes

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

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

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

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

If satisfactory evidence of payment of any applicable transfer taxes or an
exemption from payment of any applicable taxes is not submitted with the
applicable letter of transmittal, the amount of the transfer taxes will be
billed directly to that tendering holder and the exchange agent will retain
possession of an amount of new notes with a face amount at least equal to the
amount of the transfer taxes due pending receipt by the exchange agent of the
amount of the taxes due.

Consequences of Failure to Exchange

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

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

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

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

If you tender in an exchange offer for the purpose of participating in a
distribution of the new notes, you both:

  . cannot rely on the applicable interpretations of the SEC; and

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

Accounting Treatment

   We will not recognize a gain or loss for accounting purposes upon the
consummation of any of the exchange offers. We will amortize expenses of each
of the exchange offers over the terms of the respective new notes under
generally accepted accounting principles.

Other

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

                                       39
<PAGE>

   We may, in the future, seek to acquire untendered outstanding notes in open
market or privately negotiated transactions, through subsequent exchange offers
or otherwise. We have no present plans to acquire any outstanding notes that
are not tendered in the exchange offers or to file a registration statement to
permit resales of any untendered outstanding notes.

                                Use of Proceeds

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

   We used the net proceeds from the May 1999 sale of the outstanding notes,
together with the net proceeds from our May 1999 offering of common stock and
new borrowings under the credit facility, to repay in full the $3.25 billion
outstanding under term loan C and term loan D of the credit facility and to
partially repay amounts outstanding under term loan A of our credit facility.

   The following table shows the capitalization of Lyondell as of March 31,
1999 on an historical basis and as adjusted to reflect the May 1999 sale of the
outstanding notes, together with the concurrent offering of common stock and

these activities.

    $713 million of which is Equistar debt for which Lyondell remains
    contingently liable.
(b) The decrease reflects application of proceeds net of credit facility
    amendment fees and debt issuance costs aggregating $106 million. As of
    March 31, 1999, debt under the credit facility was secured by a pledge of
    subsidiary stock and a pledge of Lyondell's rights to distributions from
    some existing joint ventures. Lyondell granted additional security in
    connection with the credit facility amendments in May 1999.
(c) Debentures were not secured as of March 31, 1999, but were secured at the

(d) The decrease reflects write-offs of the deferred debt issuance costs and
    credit facility amendment fees, net of tax.

                           Lyondell Chemical Company
               Notes to Unaudited Pro Forma Financial Statements

(a) To reflect the write-off of deferred debt issuance costs and credit
    facility amendment fees of term loan C and term loan D and the partial
    write-off of deferred debt issuance costs and credit facility amendment
    fees of term loan A, offset by the impact of deferred taxes.
(b) To reflect payment and capitalization of debt issuance costs and credit
    facility amendment fees. Payments were made from proceeds of debt and
    equity offerings.
(c) To reflect the repayment of term loan C and term loan D and the partial
    repayment of term loan A with net proceeds from the sales of common stock
    and Senior Secured Notes and Senior Subordinated Notes and the borrowing of
    term loan E and term loan F.
(d) To reflect the sale of Senior Secured Notes and Senior Subordinated Notes
    and the borrowing of term loan E and term loan F.
(e) To reflect issuance of 40,250,000 shares of common stock at $19 per share
    less underwriting discounts.
(f) To reflect interest expense related to the sale of $900 million of 9 5/8%
    Senior Secured Notes, Series A, $1.0 billion of 9 7/8% Senior Secured
    Notes, Series B, and $500 million of 10 7/8% Senior Subordinated Notes, the
    borrowing of a $850 million term loan E and a $150 million term loan F and
    a 1.25% increase in the interest rate on the remaining portions of term
    loan A and term loan B. The impact of an increase in the LIBOR rate of 1/8
    of 1% would be to increase pro forma interest expense by approximately $4
    million for the year ended December 31, 1998 and $1 million each for the
    three months ended March 31, 1998 and 1999.
(g) To reflect elimination of interest expense as a result of repayment of term
    loan C and term loan D and the partial repayment of term loan A.
(h) To eliminate amortization expense of debt issuance costs due to repayment
    of term loan C and term loan D and the partial repayment of term loan A.
(i) To reflect amortization expense resulting from $89 million in debt issuance
    costs amortized over the life of the notes and term loan E and term loan F
    and a $17 million credit facility amendment fee amortized over the life of
    the credit facility, as amended.
(j) To reflect the tax effect of the pro forma adjustments and to adjust the
    tax provision to Lyondell's estimated income tax rate of 41.5% for the
    periods presented. State income tax is the primary difference between the
    estimated tax rate and the 35% federal statutory rate.
(k) To adjust depreciation expense for the estimated fair value of the acquired
    Lyondell Worldwide property, plant and equipment over an average useful
    life of 25 years. The purchase price allocation is preliminary. Lyondell is
    awaiting additional information related to the fair value of some assets
    acquired and liabilities assumed. Management does not expect the final
    determination of these matters to have a material effect on the purchase
    price allocation.
(l) To reflect amortization of goodwill and additional amortization expense for
    the estimated increase in other intangibles over periods ranging from four
    to 40 years.
(m) To reflect elimination of the historical Lyondell and Lyondell Worldwide
    interest expense.
(n) To reflect interest expense related to the issuance of the $2 billion term
    loan A, $1.25 billion term loan C and $2 billion term loan D, each at LIBOR
    plus 2%, combined with the historical interest expense on the $624 million
    Lyondell Worldwide debentures. LIBOR was 5.5% for the periods presented.
(o) To reflect amortization expense resulting from $129 million in debt
    issuance costs from financings under the credit facility over periods
    ranging from one to seven years.
(p) The unaudited pro forma income statement does not reflect a $50 million

               Management's Discussion and Analysis of Financial
                      Condition and Results of Operations

   The following discussion is a description of Lyondell's business affairs
that we believe are material at this time. You should read it in conjunction
with the financial statements of Lyondell, Equistar and LYONDELL-CITGO Refining
and the notes to those statements included in this prospectus and incorporated
by reference to Lyondell's annual report on Form 10-K for the year ended
December 31, 1998 and quarterly report on Form 10-Q for the period ended March
31, 1999.

General

   Lyondell operates in the intermediate chemicals and derivatives segment and,
through its interests in Equistar, LYONDELL-CITGO Refining and Lyondell
Methanol, operates in the petrochemicals, polymers, refining and methanol
segments. Lyondell accounts for its investments in Equistar, LYONDELL-CITGO
Refining and Lyondell Methanol using the equity method of accounting. During
the third quarter of 1998, Lyondell acquired all of the outstanding shares of
ARCO Chemical Company, now Lyondell Worldwide. Lyondell Worldwide is treated as
a separate business segment, the intermediate chemicals and derivatives
segment. Lyondell obtained its credit facility to finance the acquisition,
paying $5.6 billion for the Lyondell Worldwide stock and assuming approximately
$870 million of Lyondell Worldwide debt, net of cash.

   The following chart shows the revenues for Lyondell and the revenues, equity
percentage owned by Lyondell and the accounting method used for each of
Lyondell's businesses for the periods indicated.

(g) Lyondell Methanol was formed in December 1996 by Lyondell and MCN

    Equistar's Channelview, Texas facility.

                             Results of Operations

   Lyondell's historical operating results reflect the cyclical and volatile
nature of both the chemical and refining industries. These industries have
historically experienced alternating periods of tight supply, causing price and
profit margins to increase, followed by periods of substantial capacity
additions, resulting in oversupply and declining prices and profit margins. The
chemical industry has experienced a downward trend since peaking in 1995.
Lyondell experienced earnings declines in 1998 compared to 1997 primarily
because of lower prices in both the chemicals and refining industries. Lyondell
believes that consecutive-period comparisons are useful in illustrating the
cyclical movement of the industries in which Lyondell and its joint ventures
operate.

First Quarter 1999 Compared to Fourth Quarter 1998

   For the first quarter of 1999, Lyondell reported net income of $2 million
compared to a loss of $27 million for the fourth quarter of 1998. The fourth
quarter loss included unusual after-tax charges of $6 million primarily related
to a new labor agreement at LYONDELL-CITGO Refining and formation costs at
Equistar. The new labor agreement at LYONDELL-CITGO Refining is expected to
result in cost savings in the near term. The first quarter net income
improvement primarily reflected higher operating income in the intermediate
chemicals and derivatives segment and higher equity income from Equistar,
partly offset by lower equity income from LYONDELL-CITGO Refining.

   Operating income of the intermediate chemicals and derivatives segment was
$129 million in the first quarter of 1999 compared to $97 million in the fourth
quarter of 1998. The improvement was primarily due to lower administrative and
acquisition-related transition costs. Income from equity investment in Equistar
increased to $13 million in the first quarter of 1999 compared to a loss of $11
million in the fourth quarter of 1998. Improved results for the petrochemicals
and polymers businesses of Equistar reflected a tighter supply/demand
situation, leading to higher prices and margins. LYONDELL-CITGO Refining equity
income decreased to $11 million in the first quarter of 1999 from $22 million
in the fourth quarter of 1998. LYONDELL-CITGO Refining operating results were
negatively affected by the impact of ongoing reduced allocations of Venezuelan
extra heavy crude oil, lower margins on crude oil purchased in the spot market
and lower crude oil processing rates.

</TABLE>

   Operating income was $129 million for the first quarter of 1999 compared to
$97 million for the fourth quarter of 1998. The improvement was primarily
attributable to lower administrative and acquisition-related transition costs
and the benefit of a seasonal increase in deicers sales volumes, partly offset
by lower PO merchant volumes and margins. Core product volumes, defined as PO,
PO derivatives and isocyanates, were flat as increased PO derivatives volumes,
primarily deicers, were offset by lower PO merchant volumes. PO merchant
volumes decreased due to reduced sales to PO co-producers and planned customer
downtime during the first quarter. PO margins declined as the market
anticipated industry capacity additions in Europe later in 1999. Styrene
monomer volumes decreased 5% in the first quarter of 1999 compared to the
fourth quarter of 1998 due to the timing of export shipments to Asia. TBA and
derivatives volumes increased 8% primarily due to higher MTBE volumes.

Petrochemicals and Polymers (Equistar)

   Equistar reported income before federal income tax of $7 million in the
first quarter of 1999 compared to a pretax loss of $51 million for the fourth
quarter of 1998. The increase was primarily attributable to higher ethylene
prices and margins, reflecting a tighter supply/demand balance in the first
quarter of 1999. Polymers prices also improved but margin improvements were
limited by higher ethylene raw material costs. The fourth quarter of 1998 was
also negatively affected by charges related to Equistar's formation.

   In February 1999, Equistar completed a $900 million offering of senior
unsecured notes. The proceeds were used to refinance existing debt and capital
lease obligations of Equistar.

   In May 1999, Equistar shut down both olefins units at its Channelview, Texas
facility due to a reoccurrence of a compressor problem in one unit and a heater
malfunction in the second unit. Both units resumed operations by the end of May
1999. Equistar expects that any financial impact related to these temporary
shutdowns will be limited by property damage insurance and business
interruption insurance.

Refining (LYONDELL-CITGO Refining)

   LYONDELL-CITGO Refining had income before federal income tax of $15 million
in the first quarter of 1999 compared to $42 million, before unusual charges,
in the fourth quarter of 1998. The unusual charge of $10 million in the fourth
quarter was related to a new labor agreement. LYONDELL-CITGO Refining operating
results were negatively affected by the impact of ongoing reduced allocations
of Venezuelan extra heavy crude oil, lower margins on crude oil purchased in
the spot market and lower crude oil processing rates. Total crude oil
processing rates averaged 255,000 barrels per day in the first quarter of 1999
compared to 273,000 barrels per day in the fourth quarter of 1998. LYONDELL-
CITGO Refining reduced crude oil processing rates in the first quarter of 1999
due to declining margins on crude oil purchased in the spot market.

   LYONDELL-CITGO Refining's financial results continue to be impacted by
reductions in PDVSA crude oil allocations, which began in August 1998 and
continued following a March 1999 OPEC agreement to further

                                       54
<PAGE>

limit oil production. Reduced allocations of crude oil supplied by PDVSA force
LYONDELL-CITGO Refining to purchase a portion of its crude oil in the spot
market, thereby reducing LYONDELL-CITGO Refining's pretax income and,
accordingly, Lyondell's pro rata share of LYONDELL-CITGO Refining's income.
Even though LYONDELL-CITGO Refining may continue to receive a reduced crude oil
allocation from PDVSA, LYONDELL-CITGO Refining has begun to see some
improvement in the spot margins for crude oil.

   On May 3, 1999, LYONDELL-CITGO Refining shut down a fluid catalytic cracker
with a capacity of 92,000 barrels per day as a result of a malfunction that
damaged the main air blower. The unit resumed operations in late May 1999. On
May 7, 1999, LYONDELL-CITGO Refining shut down one of two coker units following
a fire. LYONDELL-CITGO Refining estimates that the damaged coker will resume
full operations by early July 1999. As a result of these incidents, crude oil
processing rates have been reduced. LYONDELL-CITGO Refining is currently
putting Venezuelan crude oil into inventory and expects to benefit from higher
processing rates once repairs have been completed. To the extent the business
interruption impact and the cost of repairs exceed insurance deductibles of $10
million each, per incident, Lyondell expects any excess cost to be covered by
insurance.

First Quarter of 1999 Compared to First Quarter of 1998

Intermediate Chemicals and Derivatives (Lyondell Worldwide)

   Net income. Net income of $2 million in the first quarter of 1999 decreased
from $65 million in the first quarter of 1998. Pretax income from equity
investments decreased $96 million, or about $61 million after tax, in the first
quarter of 1999 compared to the first quarter of 1998. Operating income of
Lyondell Worldwide in the first quarter of 1999 was more than offset by higher
interest expense related to Lyondell's credit facility.

   Revenues, Operating Costs and Expenses. The revenues and operating costs and
expenses for the first quarter of 1999 primarily consist of the operating
results of Lyondell Worldwide, which are included prospectively from August 1,
1998. The first quarter of 1998 includes only Lyondell's administrative
expenses. Income from Lyondell's interests in Equistar, LYONDELL-CITGO Refining
and Lyondell Methanol is reported as income from equity investments.

   Income from Equity Investments. Income from equity investments decreased
substantially from $117 million in the first quarter of 1998 to $21 million in
the first quarter of 1999.

   Lyondell's income from its equity investment in Equistar was $13 million in
the first quarter of 1999 compared to $76 million for the first quarter of
1998. The decrease was attributable to substantially lower ethylene and
polymers prices and margins in the first quarter of 1999 compared with the same
period for 1998, reflecting ongoing excess industry capacity. The first quarter
of 1999 benefit from the addition of the Occidental assets in May 1998 was
substantially offset by costs associated with the LaPorte, Texas plant
maintenance and operating problems at two of Equistar's plants in the first
quarter of 1999.

   Lyondell's income from its equity investment in LYONDELL-CITGO Refining was
$11 million in the first quarter of 1999 compared to $35 million for the first
quarter of 1998. The decline was primarily due to reduced allocations of extra
heavy Venezuelan crude oil under the LYONDELL-CITGO Refining crude supply
agreement.

   Interest Expense. Interest expense was $146 million in the first quarter of
1999 compared to $7 million in the first quarter of 1998. The increase reflects
higher debt levels as a result of amounts borrowed under Lyondell's credit
facility and debt assumed as part of the acquisition of Lyondell Worldwide.

Petrochemicals and Polymers (Equistar)

   Revenues. Petrochemical revenues for the first quarter of 1999 increased
compared to the first quarter of 1998, primarily due to increased sales volumes
as a result of the addition of the Occidental assets in May 1998. This increase
was partially offset by lower industry sales prices for ethylene, propylene and
co-products. The decrease in industry sales prices is primarily attributable to
ongoing excess industry capacity and downward pressure from raw materials
costs, which declined throughout 1998. The sales price decreases began in the
fourth quarter of 1997 and continued their downward trend through most of 1998.
U.S. market sales prices increased during the first quarter of 1999, but
average prices in the first quarter of 1999 were still lower compared to the
first quarter of 1998.

   Polymers revenues decreased in the first quarter of 1999 compared to the
first quarter of 1998 as a result of decreases in industry sales prices, partly
offset by a 6% increase in volumes. The sales price decreases reflect excess
industry supply, as industry capacity additions exceeded demand growth, and
downward pressure from raw materials costs, which declined throughout 1998. The
decreases in sales prices started during the fourth quarter of 1997 and
continued in a downward trend through 1998. Industry prices increased during
the first quarter of 1999, however average first quarter of 1999 prices were
significantly lower than the first quarter of 1998. The volume increase
reflects additional polyethylene capacity.

   Operating Income. Petrochemicals operating income decreased in the first
quarter of 1999 compared to the first quarter of 1998 primarily due to lower
product margins, as industry sales prices declined more than raw materials
costs, and the effects of the LaPorte plant maintenance in the 1999 period.
These were partly offset by the benefit of increased volumes as a result of the
addition of the Occidental assets in May 1998.

   Polymers operating income for the first quarter of 1999 decreased compared
to first quarter of 1998 primarily due to decreases in polymers sales prices,
which more than offset decreases in polymers raw materials costs, reducing
product margins.

   Interest expense. Interest expense increased from $32 million in the first
quarter of 1998 to $43 million in the first quarter of 1999, primarily
reflecting higher levels of long-term debt due to the addition of the
Occidental assets in May 1998.

Refining (LYONDELL-CITGO Refining)

   Revenues. Revenues for LYONDELL-CITGO Refining were $432 million in the
first quarter of 1999 compared to $529 million in the 1998 period. The decrease
primarily resulted from lower industry prices for refined products, partly
offset by a 7% increase in refined products volumes. Sales prices declined as a
result of lower industry crude oil prices in the first quarter of 1999 compared
to the 1998 period.

   Operating Income. LYONDELL-CITGO Refining's operating income was $24 million
in the first quarter of 1999 compared to $65 million in the first quarter of
1998. The decrease primarily reflected the effects of reduced allocations of
extra heavy Venezuelan crude oil.

1998 Compared to 1997

Intermediate Chemicals and Derivatives (Lyondell Worldwide)

   The following discussion compares Lyondell's pro forma 1998 results to pro
forma 1997 results. The pro forma adjustments give effect to:

  . the Lyondell Worldwide acquisition and related debt financing which
    occurred in July 1998;

  . the formation of Equistar which occurred in December 1997; and

  . the deconsolidation of Lyondell Methanol which occurred in January 1998

as if each occurred as of January 1, 1997 and 1998, respectively.

  These pro forma adjustments are intended to facilitate a comparison of the
results of the intermediate chemicals and derivatives business. Although
Lyondell believes that the assumptions underlying these pro

                                       56
<PAGE>

forma adjustments are reasonable and provide a reasonable basis for analyzing
changes in the intermediate chemicals and derivatives business from 1997 to
1998, the amounts presented below are not intended to reflect what the results
of operations of Lyondell and Lyondell Worldwide would have been had the
transactions reflected in the pro forma adjustments actually occurred as of the
dates given.

</TABLE>

   Revenues. Pro forma revenues of $3.6 billion for 1998 decreased 11% compared
to $4.0 billion for 1997. The decrease of $442 million was primarily due to
lower average sales prices in 1998, reflecting a combination of:

  . downward pressure from lower raw materials costs;

  . ongoing competition in PO derivatives and TDI markets;

  . the negative effects of a stronger U.S. dollar on foreign sales; and

  . the effects of weaker Asian markets.

PO and PO derivatives volumes were essentially flat in 1998 versus 1997 as
stronger demand for some PO derivatives in the United States and Europe was
offset by lower volumes in Asian markets. The increase in styrene monomer
volumes in 1998 was a result of the capacity expansion at the PO facility in
Channelview, Texas completed in the second quarter of 1998. The increased
capacity was dedicated to long-term styrene monomer processing arrangements.
TBA and derivatives volumes decreased 6% in 1998, mainly due to lower MTBE
demand.

   Operating costs. Pro forma cost of sales of $2.7 billion for 1998 decreased
15% compared to $3.2 billion for 1997. The 15% decrease was greater than the
11% decrease in revenues, reflecting comparatively lower raw material prices.
Pro forma selling, general and administrative and research and development
expenses of $344 million for 1998 remained flat as compared to 1997.

   Operating income. Pro forma operating income of $396 million for 1998
increased by 146% compared to $161 million for 1997. Operating income for 1998
reflected unusual charges of $41 million, primarily related to the write-off of
in-process research and development projects of Lyondell Worldwide and Equistar
formation costs. Operating income for 1997 reflected unusual charges of $191
million, primarily related to restructuring and other costs of Lyondell
Worldwide and Equistar formation costs. Excluding these items, operating income
of $437 million for 1998 increased by $85 million.

   Net income. Pro forma net income of $42 million for 1998 increased 55%
compared to $27 million for 1997. Excluding the effects of the unusual charges
in both years, pro forma net income of $66 million for 1998 decreased $84
million compared to 1997 as lower equity income from the joint ventures more
than offset improved operating results and lower foreign exchange losses of
Lyondell Worldwide.

Petrochemicals and Polymers (Equistar)

   The following discussion compares Equistar's actual 1998 results to combined
1997 results. The 1998 results include results attributable to the Occidental
assets contributed to Equistar from May 15, 1998, the date on which they were
contributed. The 1997 results have been prepared on a pro forma basis and
combine 11 months of the operations of the businesses contributed to Equistar
by Lyondell and Millennium Chemicals and

                                       57
<PAGE>

one month of Equistar's actual operations. These pro forma adjustments are
intended to facilitate a comparison of the results of the petrochemicals and
polymers business. Although Lyondell believes that the assumptions underlying
these pro forma adjustments are reasonable and provide a reasonable basis for
analyzing changes in the Equistar business from 1997 to 1998, the amounts
presented below are not intended to reflect what the results of operations of
Equistar would have been had the transactions reflected in the pro forma
adjustments actually occurred as of the dates given and are not necessarily
indicative of future operations of Equistar.

Petrochemicals

   Revenues. Petrochemicals revenues of $3.5 billion for 1998 decreased 10%
compared to combined 1997 revenues of $3.9 billion. The decrease is primarily
due to lower industry sales prices for ethylene, propylene and co-products,
partially offset by increased sales volumes as a result of the addition of the
Occidental assets in May 1998. The decrease in sales prices is primarily
attributable to increased industry capacity and downward pressure on sales
prices as a result of lower raw materials costs. The sales price decreases
began in the fourth quarter of 1997 and continued their downward trend through
most of 1998. Ethylene and propylene volumes were 16,716 million pounds in
1998, a 77% increase over combined volumes of 9,429 million pounds in 1997. The
increase in ethylene and propylene volumes is primarily a result of the
addition of the Occidental assets. Aromatics volumes were 271 million gallons
in 1998, a 40% increase over combined volumes of 193 million gallons in 1997.
The increase in aromatics volumes is primarily a result of the addition of the
Occidental assets.

   Operating costs. Petrochemicals cost of sales of $3.1 billion for 1998
decreased 1% from $3.2 billion for combined 1997. This decrease was less than
the 10% decrease in revenues, reflecting the fact that raw materials prices
declined at a slower rate than petrochemicals product prices. Petrochemicals
selling expenses of $14 million for 1998 decreased 55% from $31 million for
1997. This decrease reflected lower personnel costs as a result of
consolidation of operations.

   Operating income. Petrochemicals operating income of $319 million for 1998
decreased 53% compared to combined 1997 operating income of $684 million,
primarily due to lower product margins as sales prices declined more than raw
materials costs and, to a lesser extent, slightly higher fixed costs. The
decrease in operating income as a result of the lower margins was partially
offset by the addition of the Occidental assets in May 1998.

Polymers

   Revenues. Polymers revenues of $2.1 billion for 1998 decreased 18% compared
to combined 1997 revenues of $2.5 billion as a result of decreases in industry
sales prices. These sales price decreases were a result of excess industry
supply and lower raw materials costs. The excess industry supply started during
the fourth quarter of 1997 and continued in a downward trend through 1998.
Polymers volumes were 6,488 million pounds in 1998, a 6% increase over combined
volumes of 6,132 million pounds in 1997. Volume increases were a result of
capacity additions at three facilities, as well as unscheduled industry
outages, in 1997.

   Operating costs. Polymers cost of sales of $1.8 billion for 1998 decreased
16% from $2.1 billion for combined 1997. This decrease was less than the 18%
decrease in revenues, reflecting the fact that raw materials prices declined at
a slower rate than polymers product prices. Polymers selling expenses of $82
million for 1998 decreased 40% from $137 million for combined 1997. This
decrease primarily reflected lower personnel costs as a result of consolidation
of operations.

   Operating income. Polymers operating income of $177 million for 1998
decreased 24% compared to combined 1997 operating income of $233 million. The
decrease is primarily due to decreases in polymers sales prices, which more
than offset decreases in polymers raw materials costs.

Restructuring Charges

   Equistar's unusual charges, which are not allocated to either the
petrochemicals or polymers segments, were $42 million in 1997 and $35 million
in 1998. Both years included costs associated with the formation of

                                       58
<PAGE>

Equistar and the consolidation of some operations. These costs were paid by
Equistar and allocated to the Equistar partners according to their ownership
percentages.

Refining (LYONDELL-CITGO Refining)

   The following discussion compares LYONDELL-CITGO Refining's actual 1998
results to its actual 1997 results.

   Increased processing capacity resulting from the upgrade project enabled
LYONDELL-CITGO Refining to increase its crude processing rates and produce
greater refined product volumes, as shown in the table below.

</TABLE>

   Revenues. Revenues for LYONDELL-CITGO Refining, including sales to
affiliates, of $2.1 billion for 1998 decreased 22% compared to $2.7 billion for
1997. The decrease primarily resulted from lower refined products prices, which
declined as a result of lower industry crude prices. These decreases were
partially offset by higher sales volumes as production levels increased,
reflecting a full year's benefit from the upgrade project.

   Operating costs. LYONDELL-CITGO Refining's cost of sales of $1.8 billion for
1998 decreased 28% from $2.5 billion for 1997. The benefits of lower raw
material prices under the crude supply agreement were offset in part by the
lower allocations under that agreement, which began in August 1998 and required
LYONDELL-CITGO Refining to seek additional crude oil at higher prices in the
spot market. LYONDELL-CITGO Refining's selling, general and administrative
expenses of $78 million for 1998 increased 8% from $72 million for 1997. This
increase reflected increased coke handling charges and other selling costs
related to increased production and higher sales volumes.

   Operating income. LYONDELL-CITGO Refining's operating income of $213 million
for 1998 increased 18% compared to $183 million for 1997. The increase
reflected the benefits of the upgrade project, which resulted in higher average
margins as higher volumes of extra heavy crude oil were processed in the coking
mode. The upgrade project was completed in the first quarter of 1997.
Initially, higher costs were incurred due to normal operational start-up
activities during which the refinery did not operate at peak rates. Cost
savings resulting from improved operational efficiency in 1998 were partly
offset by higher depreciation expense attributable to the upgrade project.

   Interest expense. LYONDELL-CITGO Refining's net interest expense of $43
million for 1998 increased 23% compared to $35 million for 1997. Interest
expense on debt related to construction of the upgrade project was capitalized
through its completion, including the first quarter of 1997.

Methanol (Lyondell Methanol)

   Lyondell's share of Lyondell Methanol's earnings for 1998 was $6 million.
Lyondell would have recorded approximately $43 million for its share of
Lyondell Methanol's earnings had Lyondell followed the equity method of
accounting for its investment in Lyondell Methanol during 1997. The decrease
was due to significant declines in the sales prices of methanol beginning in
the first quarter of 1998. Increased supply due to new capacity, as well as
weaker demand from Asia, caused worldwide methanol price declines.

                        Liquidity and Capital Resources

 Cash Flows

   Operating activities. Lyondell's cash provided by operating activities
totaled $263 million for 1998, a 2% decrease compared to $269 million for 1997.
Cash provided by operating activities in 1998 included $160 million of proceeds
from the sale of domestic receivables in December 1998 under a three-year
revolving securitization agreement. Cash provided by operations in 1998 was
negatively affected by the payment of liabilities associated with the
acquisition of Lyondell Worldwide and the settlement of accounts payable
retained by Lyondell in the formation of Equistar in December 1997.

   Investing activities. Lyondell completed the acquisition of Lyondell
Worldwide on July 28, 1998 for a total cost of approximately $5.9 billion,
excluding assumed debt. Lyondell made capital expenditures of $64 million in
1998, primarily related to Lyondell Worldwide. Equistar's 1998 capital
expenditures totaled $200 million, of which $88 million was Lyondell's pro rata
share. LYONDELL-CITGO Refining made 1998 capital expenditures of $61 million,
of which Lyondell funded $35 million through loans to LYONDELL-CITGO Refining.
Lyondell's 1999 capital budget is $273 million, including its $123 million pro
rata share of its joint ventures' capital budgets.

   Distributions in excess of earnings for 1998 were $403 million by Equistar,
$20 million by LYONDELL-CITGO Refining and $12 million by Lyondell Methanol.
The $403 million excess distribution from Equistar includes $197 million
resulting from Lyondell's repayment of a $345 million note to Equistar.

   Financing activities. Cash provided by financing activities was $5.4 billion
for 1998, compared to cash used in financing activities of $176 million for
1997. During the third quarter of 1998, Lyondell obtained its $7 billion credit
facility. Lyondell's $6.5 billion borrowing under the credit facility in
connection with the Lyondell Worldwide acquisition was used for:

  . the purchase of all outstanding shares of Lyondell Worldwide stock;

  . repayment of debt, including a $345 million note to Equistar and $283
    million in other debt of Lyondell and Lyondell Worldwide; and

  . payment of some debt issuance costs.

As part of the acquisition, Lyondell also assumed approximately $870 million of
Lyondell Worldwide debt.

   Cash used in other financing activities in 1998 consisted primarily of $59
million used to repurchase Lyondell common stock. From time to time Lyondell
purchases its shares in the market to issue under Lyondell's employee
compensation and benefits plans, including stock option and restricted stock
plans. In addition, in the second quarter of 1998 Lyondell completed a stock
buyback program authorized in September 1997. A total of 2,567,051 shares were
purchased under the program for $75 million.

   Lyondell paid regular quarterly dividends of $.225 per share of common stock
in 1998 and for the first quarter of 1999.

 Debt

   As of May 31, 1999, Lyondell had outstanding consolidated debt of $6.3
billion and equity of $1.2 billion. Substantially all of the debt was incurred
in July 1998 under the credit facility for the purpose of acquiring Lyondell
Worldwide or was assumed as part of the acquisition.

                                       60
<PAGE>

   In May 1999, Lyondell completed a partial refinancing of the debt under its
credit facility. The refinancing reduced consolidated debt by approximately
$630 million and eliminated substantially all debt maturities through year end
2000 by refinancing longer-term debt. The refinancing consisted of:

  .the issuance of the outstanding notes for gross proceeds of $2.4 billion;

  .the borrowing of an additional $1 billion under two new term loans under
     the credit facility; and

  . the issuance of 40.25 million shares of Lyondell common stock for gross
    proceeds of $765 million.

   In addition, as of May 31, 1999, Equistar, LYONDELL-CITGO Refining and
Lyondell Methanol had, in the aggregate, outstanding debt of approximately $3.1
billion and equity of approximately $4.5 billion. The ability of the joint
ventures to distribute cash to Lyondell is reduced by their respective debt
service obligations. Furthermore, a default under some joint venture debt
agreements would constitute a cross-default under Lyondell's credit facility.
Following repayment at maturity of Equistar's 10% Notes due June 1, 1999,
Lyondell currently remains liable on approximately $563 million of debt for
which primary responsibility was assumed by Equistar in connection with its
formation. See "Description of Other Indebtedness--Joint Venture Debt" for a
description of the debt of the joint ventures.

   To reduce its debt, Lyondell is looking to:

  . the cash flow of its businesses;

  . potential joint ventures involving strategic assets;

  . new equity capital;

  . working capital initiatives;

  . potential asset sales;

  . refinancing programs; and

  . other cash generating opportunities.

   Lyondell continues to believe that repositioning its balance sheet to
achieve an investment grade rating over time is an important objective. The
ability of Lyondell to:

  . meet its debt obligations;

  . finance its capital expenditure needs;

  . maintain its dividend rate; and

  . comply with the covenants and financial requirements in the credit
    facility

will generally depend on the future performance of Lyondell and the
availability and terms of additional financing or alternative means to repay
and refinance bank debt. These factors, in turn, are affected by relevant
prevailing economic, competitive and market conditions and other factors beyond
Lyondell's control. The breach of any of the covenants or financial
requirements in the credit facility could result in a default, which would
permit the lenders to declare the loans immediately payable and to terminate
future lending commitments. A default under the credit facility would also
result in an acceleration of the maturity of the new notes.

   Lyondell believes that cash balances, cash generated from operating
activities, and funds from financing activities and lines of credit will be
adequate to meet anticipated future cash requirements for scheduled debt
repayments, necessary capital expenditures and dividends. See "Risk Factors."

   Under Internal Revenue Code Sections 338 (g) and (h)(10), Lyondell and the
former majority stockholder of Lyondell Worldwide agreed to elect to step-up
the United States tax bases of Lyondell Worldwide's net assets. This will
result in significant increased depreciation and amortization with resulting
United States tax savings. The total value of these savings is expected to be
between $800 million and $1 billion over time.

                              Business of Lyondell

   Our annual report on Form 10-K for the year ended December 31, 1998 contains
a complete description of our businesses. Described below is a discussion of
our strategy for the following business segments:

  . intermediate chemicals and derivatives;

  . petrochemicals and polymers;

  . refining; and

  . methanol.

Also included is a description of the business of Lyondell Worldwide and
Lyondell Nederland, the guarantors of the new notes.

                          Business Segment Strategies

Intermediate Chemicals and Derivatives (Lyondell Worldwide)

 PO and its Derivatives

   Lyondell intends to maintain its leading market positions in its major
products. It intends to be a major participant in the global growth of PO,
urethanes and performance chemicals, building from its strengths in the areas
of:

  . technology;

  . manufacturing;

  . marketing; and

  . access to raw materials.

   Over the past 25 years, the annual global industry growth rate for PO and
its derivatives has averaged approximately 5%. Lyondell expects similar growth
to continue into the future. Global demand for PO was estimated at
approximately 8.7 billion pounds in 1998. Approximately 90% of that volume was
consumed in the manufacture of three families of PO derivatives products:
polyols, propylene glycol and propylene glycol ethers. The remainder was
consumed in the manufacture of a growing segment of performance-based products,
as well as butanediol and its derivatives. Lyondell intends to increase both
its overall production of PO and its production of PO derivatives while
continuing its participation in the PO merchant market, an important source of
revenue and profit for Lyondell.

   Lyondell is a major participant in the global urethanes chemicals market
through its production of polyols and TDI. Lyondell's strategy is to grow its
urethanes business using its proprietary Impact(TM) polyols processing
technology first introduced in 1995. This technology offers significant cost
savings in the production of conventional polyols products. It is also key to
the development of new, superior quality products for markets such as footwear,
carpet backing and spandex. To date, Lyondell has been granted 66 patents and
has over 34 patents pending for this technology. Lyondell plans to retrofit
most of its polyols production facilities to utilize Impact(TM) technology over
the next five years.

   Lyondell has the only PO-based processing route to butanediol. This
efficient proprietary technology provides Lyondell with a competitive advantage
in the rapidly expanding markets for butanediol and its derivatives. Butanediol
and its derivatives represent a global market growing at 7% per year and
provide access to markets such as:

  . pharmaceuticals;

  . personal care products;

                                       62
<PAGE>

  . fibers; and

  . high performance coatings.

   The co-products produced from Lyondell's two PO processes are TBA and
styrene monomer. Lyondell's strategy is to maximize earnings contribution from
these products.

 Cost Savings

   In late 1997, Lyondell Worldwide initiated a restructuring program designed
to simplify its organization, streamline operations and reduce costs. Lyondell
expects to achieve these cost savings by the end of 1999. Lyondell's management
believes that it will be able to realize additional cost savings through:

  . overhead consolidation;

  . manufacturing and purchasing efficiencies;

  . reduced transportation costs; and

  . raw materials integration with Equistar.

Petrochemicals and Polymers (Equistar)

   Equistar intends to:

  . maximize its integration opportunities with Lyondell;

  . increase its production and sales of higher value products; and

  . continue its ongoing cost reduction activities.

   The formation of Equistar provided significant integration opportunities for
Lyondell's ethylene production. Following the addition of the Occidental assets
to Equistar in May 1998, Equistar currently consumes or sells approximately 75%
of its ethylene production to downstream derivatives facilities owned by
Equistar or one of its partners, which has the effect of reducing earnings
volatility.

   The creation and subsequent expansion of Equistar were driven by the
opportunity to reduce costs significantly and realize revenue enhancements that
were not possible for the Equistar partners on a stand-alone basis. Equistar
intends to reduce costs by:

  . optimizing its processing units for improved operating efficiency and
    increased processing rates;

  . maximizing the value of its raw materials flexibility and ethylene and
    polyethylene co-products production;

  . lowering distribution costs through volume leverage; and

  . reducing raw materials and other procurement costs.

Equistar expects to achieve significant cost savings by the end of the year
2000.

   Equistar is focused on capital projects designed to lower its operating
costs. It is also currently undertaking a market strategy of expanding its
value-added product lines, including:

  . high and medium molecular weight high density polyethylene film resins;

  . value and specialty injection molding resins; and

  . wire and cable resins.

                                       63
<PAGE>

   These capacity expansions are intended to support Equistar's expected
increase in production and sales volumes for these products.

 Petrochemicals

   Equistar's business strategy for its petrochemicals business is to derive
maximum value from its internal integration, as well as integration with
Lyondell, and to improve its low cost operations. Management of Lyondell
intends to use Equistar's production of propylene, ethylene, benzene and
methanol as key raw materials for Lyondell's intermediate chemicals and
derivatives business. Equistar will continue to pursue joint ventures as the
preferred method to add ethylene and polyethylene production capacity when
needed and will aggressively pursue research on alternative ethylene and
polyethylene raw material technology to reduce the costs of raw materials. In
addition, Equistar intends to improve its low cost operations by:

  . increasing its ability to use low cost raw materials;

  . maximizing ethylene and polyethylene co-product production; and

  . reducing raw materials and product delivery costs.

 Polymers

   Equistar will promote growth in polymers by targeting value-added markets
that provide attractive margins and above average growth rates. In late 1998
Equistar completed a 125 million-pound expansion at its Victoria, Texas
facility. A 480 million-pound expansion of its Matagorda, Texas facility is
expected to be completed in the third quarter of 1999. These expansions will
provide necessary capacity for the high and medium molecular weight high
density polyethylene market. These are areas in which Equistar has a leading
market position and for which demand is growing at 2 to 3% above average
polyethylene growth.

   Equistar continues to pursue technological innovation for its polymers
segment to create new polymers products. With the recent addition of the
Occidental assets to Equistar in May 1998, Lyondell benefits from access to
Occidental's processing technologies. To date, Equistar has received eight
fundamental patents and has nine patents pending for its single-site catalyst
technology. This technology is expected to lead to the development of higher
value polymers products with enhanced performance characteristics, including
improved puncture resistance, impact strength and clarity.

Refining (LYONDELL-CITGO Refining)

   LYONDELL-CITGO Refining's business strategy focuses on improving its ability
to process low cost, extra heavy crude oil, thereby enabling LYONDELL-CITGO
Refining to capitalize on the favorable economics of its crude supply agreement
and to increase profitability with little additional fixed cost. LYONDELL-CITGO
Refining has already demonstrated its ability to exceed the refinery's designed
processing rate of 230,000 barrels per day of extra heavy crude oil. Peak
processing rates of approximately 270,000 barrels per day have been achieved.
LYONDELL-CITGO Refining is developing a plan to increase the refinery's
capability to process up to 300,000 barrels per day with modest capital
investment and minimal changes to the refinery's fixed cost structure. This
capability, when coupled with LYONDELL-CITGO Refining's advantageous formula-
priced long-term crude supply agreement with PDVSA, helps to stabilize earnings
and cash flow. In addition to increasing processing capacity, LYONDELL-CITGO
Refining is improving its profitability by increasing its yield of high value
products produced per barrel of crude processed. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Results of
Operations--First Quarter of 1999 compared to Fourth Quarter 1998--Refining."

   Lyondell seeks to position the LYONDELL-CITGO Refining refinery in the top
quartile of the industry in cost structure. LYONDELL-CITGO Refining continues
to improve its low cost operations through:

  . aggressive energy conservation programs;

  . improving its yields to increase operational efficiency; and

  . improving equipment reliability to maximize processing rates and minimize
    downtime.

                                       64
<PAGE>

   LYONDELL-CITGO Refining has reduced its number of employees in connection
with its new labor agreement and will outsource non-core activities.

Methanol (Lyondell Methanol)

   Lyondell Methanol's strategy is to achieve efficient, low cost operations.
Lyondell Methanol intends to:

  . reduce raw materials costs;

  . increase contract sales;

  . implement cost reduction technologies and techniques;

  . maximize the chemical efficiency of its processes through research into
    alternative raw materials; and

  . achieve competitive raw material supply advantages with Lyondell's other
    businesses.

   You are cautioned that Lyondell's ability to undertake and fund the
business strategies described above will be affected by a variety of factors,
some of which are beyond Lyondell's control. See "Forward-Looking Information"
on page 29.

             Business of Lyondell Worldwide and Lyondell Nederland

                                    Products

   The following charts show the products produced by Lyondell, Equistar and
LYONDELL-CITGO Refining, including:

  . the location of manufacturing facilities;

  . production capacity;

  . major competitors; and

  . primary uses.

   Unless otherwise specified, in the table below, production capacity was
calculated by estimating the number of days in a typical year that a production
unit of a plant is expected to operate, after allowing for downtime for regular
maintenance, and multiplying that number by an amount equal to the unit's
optimal daily output based on the current design raw material mix. Because
production capacity of a production unit is an estimated amount, the actual
production volumes may be more or less than the production capacity listed.
Production capacity shown for Equistar is 100% of the production capacity of
Equistar, of which Lyondell owns a 41% interest. Production capacity shown for
LYONDELL-CITGO Refining is 100% of the production capacity of LYONDELL-CITGO
Refining, of which Lyondell owns a 58.75% interest.

   pounds in 1998. A 480 million pound HDPE resin expansion project at the
   Matagorda, Texas facility has a targeted start-up in the third quarter of
   1999. The idling of the Port Arthur, Texas facility effective March 31, 1999
   has resulted in a decrease in production capacity of 300 million pounds per
   year.

                       Description of Other Indebtedness

Credit Facility

   In July 1998, Lyondell acquired all the outstanding shares of common stock
of Lyondell Worldwide for $6.5 billion, which included $5.6 billion for the
purchase of common stock and the assumption or refinancing of approximately
$870 million in debt, net of cash. Funding for the acquisition, the repayment
of some Lyondell and Lyondell Worldwide debt and related fees and expenses was
provided through the credit facility. In May 1999, the credit facility was
amended, two of the original term loans were repaid and two new term loans were
borrowed. The amended credit facility consists of a 5-year revolving credit
facility of up to $500 million to be used for general corporate purposes and
four separate term loans. No amounts to date have been funded under the
revolving credit facility. As of May 31, 1999, the principal amounts
outstanding, interest rates and maturity dates of the term loans were as
follows:

</TABLE>

 Covenants

   The amended credit facility requires Lyondell to issue, in one or more
transactions, not less than $470 million of additional subordinated notes (or
more junior securities) by June 30, 2002. This requirement will be reduced by
$2 for every $1 of common stock issued in the future and will be eliminated if
Lyondell achieves either:

  . a total debt to adjusted EBITDA ratio, as defined in the credit facility,
    of 3.0 to 1.0; or

  . a rating for its senior unsecured debt of BB by Standard & Poor's and Ba2
    by Moody's.

   Under the covenant provisions of the credit facility, as amended, Lyondell
has agreed to, among other things:

  . maintain specified financial ratios and consolidated net worth;

  . not make some distributions with respect to Lyondell's capital stock;

  . not make some investments;

  . not allow its subsidiaries to incur some types and amounts of debt; and

  . use its best efforts to maintain specified ownership interests in some of
    its existing joint ventures and to ensure that some of its existing joint
    ventures maintain specified capital expenditure and debt levels and cash
    distribution policies.

Lyondell believes that it is in compliance with each of its financial covenants
as of May 31, 1999.

                                       70
<PAGE>

 Security

   The credit facility is secured by:

  . personal property of Lyondell and Lyondell Worldwide;

  . rights to distributions from some existing joint ventures;

  . a pledge of the stock of substantially all domestic subsidiaries directly
    owned by Lyondell and Lyondell Worldwide;

  . a pledge of 65% of the stock of foreign subsidiaries directly owned by
    Lyondell and Lyondell Worldwide; and

  . the property, plant and equipment for some of Lyondell's and Lyondell
    Worldwide's facilities located in Texas and Louisiana.

Lyondell Worldwide (ARCO Chemical) Debentures

   Lyondell Worldwide has the following outstanding debentures:

  . $200 million of 9.90% debentures due 2000;

  . $100 million of 9.375% debentures due 2005;

  . $100 million of 10.25% debentures due 2010; and

  . $224 million of 9.80% debentures due 2020.

The debentures are secured by liens on Lyondell Worldwide's manufacturing
plants located in Texas and Louisiana that are equal and ratable with the liens
on those assets under the Senior Secured Notes and the loans under the credit
facility. The indentures for these debentures contain customary covenant
provisions pertaining to, among other things, limitations on liens and sale and
leaseback transactions.

Joint Venture Debt

 Equistar Debt

   In February 1999, Equistar completed a $900 million private placement of 5-
and 10-year notes, the proceeds of which were used to refinance existing
Equistar debt. Proceeds were used to:

  . repay in its entirety Equistar's $205 million outstanding capital lease
    obligation relating to its Corpus Christi, Texas facility;

  . retire at maturity $150 million aggregate principal amount of 10.00%
    Notes due June 1, 1999, for which Lyondell was a co-obligor;

  . repay approximately $152 million remaining outstanding under Equistar's
    $500 million credit agreement, which was subsequently terminated; and

  . refinance outstanding borrowings under its $1.25 billion 5-year working
    capital facility.

   As of May 31, 1999, the principal amounts outstanding, interest rates and

(a) Following the repayment at maturity of Equistar's 10% Notes due June 1,
    1999, Lyondell currently remains liable on $563 million of debt assumed by
    Equistar in connection with its formation, though Equistar has agreed to be
    primarily liable for this debt.

 Equistar Covenants

   Under the covenant provisions of its 5-year revolving credit facility,
Equistar has agreed, among other things, to:

  . maintain specified financial ratios;

  . not create specified liens on its property or assets;

  . not enter into some sale and leaseback transactions;

  . not allow its subsidiaries to incur some types of debt or issue some
    types of preferred stock;

  . not use the proceeds of its credit facility for some purposes;

  . not change its or its subsidiaries' line of business; and

  . not enter into agreements restricting the ability of some of its
    subsidiaries to pay distributions or dividends.

   Equistar believes that it is in compliance with each of its financial
covenants as of May 31, 1999.

   The ability of Equistar to meet its debt service obligations and to comply
with the covenants and financial requirements in its credit facility will
largely depend on the future performance of Equistar and the availability of
additional financing to repay and refinance bank debt. These obligations are
affected by prevailing economic, market and competitive conditions and other
factors beyond Equistar's control. The breach by Equistar of any of the
covenants or financial requirements in its credit facility could result in a
default, which would permit the lenders to declare the loans immediately
payable and to terminate future lending commitments.

 LYONDELL-CITGO Refining Debt

   As of May 31, 1999, the principal amounts outstanding, interest rates and
maturity dates of the LYONDELL-CITGO Refining debt obligations were as follows:

   In late 1998, LYONDELL-CITGO Refining postponed a planned debt refinancing.
The postponement was due to unfavorable bond market conditions and political
change in Venezuela associated with the recent presidential elections. The
proceeds of the refinancing would have been used to repay third-party
construction loans and subordinated loans made to LYONDELL-CITGO Refining by
Lyondell and CITGO, with any remaining cash distributed to the partners.
LYONDELL-CITGO Refining intends to pursue the refinancing as soon as practical.

 LYONDELL-CITGO Refining Covenants

   Under the covenant provisions of its credit agreements, LYONDELL-CITGO
Refining has agreed, among other things, to:

  . maintain specified financial ratios;

  . not enter into some transactions with affiliates;

  . not make some investments;

  . not create some liens;

  . not make some distributions or repurchases on its capital stock;

  . not allow its subsidiaries to incur some types and amounts of debt;

  . not enter into some asset sales; and

  . not take some specified actions with respect to its crude supply
    agreement, products purchase agreement or some of LYONDELL-CITGO
    Refining's formation documents.

LYONDELL-CITGO Refining believes that it is in compliance with each of its
financial covenants as of May 31, 1999.

   The ability of LYONDELL-CITGO Refining to meet its debt service obligations
and to comply with the covenants and financial requirements in its credit
agreement will largely depend on the future performance of LYONDELL-CITGO
Refining and the availability of additional financing to repay and refinance
bank debt. These obligations are affected by prevailing economic, market and
competitive conditions and other factors beyond LYONDELL-CITGO Refining's
control. The breach by LYONDELL-CITGO Refining of any of the covenants or
financial requirements in its credit agreement could result in a default, which
would permit the lenders to declare the loans immediately payable and to
terminate future lending commitments.

                            Description of New Notes

   We have summarized below the material provisions of the new notes and the
indentures. This summary does not restate these documents in their entirety.
The indentures, and not this summary, govern your rights as holders of the new
notes. Copies of the indentures and the security documents are available as
described below under "--Where You Can Find More Information."

   As used only in this "Description of New Notes," the terms "Lyondell", "us",
or "we" refer to Lyondell Chemical Company and not to any of its subsidiaries.
For definitions of some of the capitalized terms used in the following summary,
see "--Definitions."

Brief Description of the New Notes

   The new notes will be issued under three separate indentures among Lyondell,
Lyondell Worldwide and Lyondell Nederland, as guarantors, and The Bank of New
York, as trustee. The same indentures also govern the outstanding notes. The
terms of the new notes include those stated in the indentures and those made
part of the indentures by reference to the Trust Indenture Act of 1939, as
amended. The new notes are subject to all

                                       73
<PAGE>

these terms, and holders of new notes are referred to the indentures and the
Trust Indenture Act for a statement of these terms.

 Senior Secured Notes.

  The new Senior Secured Notes:

  . are general secured obligations of Lyondell

  . rank equally in right of payment with the outstanding Senior Secured
    Notes

  . rank equally with all our existing and future unsecured senior debt and
    rank senior to this debt to the extent of the value of the collateral

  . effectively rank junior to all liabilities of our joint ventures and all
    liabilities of our subsidiaries that are not guarantors

  . are secured equally and ratably with debt under our credit facility and
    some debt of Lyondell Worldwide

  . are unconditionally guaranteed by our subsidiaries Lyondell Worldwide and
    Lyondell Nederland

  . are registered under the Securities Act and freely transferable

  . have substantially the same terms as the outstanding Senior Secured
    Notes, except that they do not have registration rights.

   At May 31, 1999:

  . approximately $5.8 billion in principal amount of outstanding
    unsubordinated Indebtedness of Lyondell, Lyondell Worldwide and Lyondell
    Nederland was secured, including the Senior Secured Notes and
    Indebtedness under the Existing Credit Facility;

  . approximately $725 million of outstanding Indebtedness of Lyondell,
    Lyondell Worldwide and Lyondell Nederland was pari passu with the Senior
    Secured Notes and unsecured and ranked effectively junior to the Senior
    Secured Notes to the extent of the value of the assets securing the
    Senior Secured Notes; of this Indebtedness, $713 million is Indebtedness
    of Equistar for which Lyondell remains contingently liable and the
    balance is primarily undrawn letters of credit;

  . the $500 million in principal amount of Senior Subordinated Notes, would
    have been, by their terms, subordinated to the Senior Secured Notes.

 Senior Subordinated Notes.

  The new Senior Subordinated Notes:

  . are general unsecured obligations of Lyondell

  . rank equally in right of payment with the outstanding Senior Subordinated
    Notes

  . rank junior to all our existing and future unsubordinated debt, including
    the Senior Secured Notes, debt under our credit facility and some debt of
    Lyondell Worldwide

  . effectively rank junior to all liabilities of our joint ventures and all
    liabilities of our subsidiaries that are not guarantors

  . are unconditionally guaranteed by our subsidiaries Lyondell Worldwide and
    Lyondell Nederland

  . are registered under the Securities Act and freely transferable

  . have substantially the same terms as the outstanding Senior Subordinated
    Notes, except that they do not have registration rights.

                                       74
<PAGE>

   At May 31, 1999, approximately $5.8 billion in principal amount of Senior
Indebtedness of Lyondell, Lyondell Worldwide and Lyondell Nederland was
outstanding (including Indebtedness under the Existing Credit Facility and the
Senior Secured Notes and excluding $713 million of Equistar debt for which
Lyondell is contingently liable).

   The Guarantees. The new notes are guaranteed by our subsidiaries Lyondell
Worldwide and Lyondell Nederland.

  The guarantees of the Senior Secured Notes:

  . are general obligations of each guarantor

  . rank equally with all existing and future unsubordinated debt of each
    guarantor

  The guarantees of the Senior Subordinated Notes:

  . are general obligations of each guarantor

  . rank junior to all existing and future unsubordinated debt of each
    guarantor, including the guarantees of the Senior Secured Notes

   Structural Subordination. Many of Lyondell's operations are conducted
through its Subsidiaries and Joint Ventures. For this reason, Lyondell is
dependent upon the cash flow of its Subsidiaries and Joint Ventures to meet its
obligations, including Lyondell's obligations under the new notes. The new
notes will be effectively subordinated to all outstanding Indebtedness and
other liabilities and commitments, including trade payables and operating lease
obligations, of Lyondell's Subsidiaries and Joint Ventures, except to the
extent they are Subsidiary Guarantors. At May 31, 1999, the new notes would
have been effectively subordinated to approximately $4.0 billion of outstanding
liabilities of Lyondell's Joint Ventures, including trade payables. See "Risk
Factors--Most of the covenants under the new notes do not apply to Lyondell's
joint ventures; our joint ventures could increase their debt leverage, default
on their debt obligations or take other action limiting their ability to pay
distributions to us for which you will have no recourse."

   Upon the liquidation, reorganization or insolvency of any of Lyondell's
Subsidiaries or Joint Ventures that are not Subsidiary Guarantors, Lyondell's
rights to receive assets of these companies and the rights of holders of the
new notes to participate in those assets will be effectively subordinated to
the claims of creditors and preferred stockholders of the Subsidiary or Joint
Venture. However, in the event that Lyondell itself is recognized as a creditor
of the Subsidiary or Joint Venture, then Lyondell's claims would not be
subordinate to third party creditors and preferred stockholders, but would
still be subordinate to any lien or security interest in the assets of the
Subsidiary or Joint Venture and any Indebtedness of the Subsidiary or Joint
Venture senior to that held by Lyondell.

   Under some circumstances, Lyondell will be able to designate current or
future Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries and
Joint Ventures, so long as they are not Subsidiaries of Lyondell (and, if they
are Subsidiaries, at any time that they are designated as Unrestricted
Subsidiaries), will not be subject to many of the restrictive covenants
specified in the indentures.

Principal, Maturity And Interest

   Senior Secured Notes. The Series A Senior Secured Notes will be secured,
senior obligations of Lyondell initially limited in aggregate principal amount
to $900 million and will mature on May 1, 2007. The Series B Senior Secured
Notes will be secured, senior obligations of Lyondell initially limited in
aggregate principal amount to $1 billion and will mature on May 1, 2007.
Interest on the Series A Senior Secured Notes is 9 5/8% per annum. Interest on
the Series B Senior Secured Notes is 9 7/8% per annum. Interest on both the
Series A Senior Secured Notes and Series B Senior Secured Notes is payable
semi-annually in arrears on May 1 and November 1 of each year, beginning on
November 1, 1999, to holders of record on the immediately preceding April 15
and October 15, respectively. Interest on the Senior Secured Notes will accrue
from the most recent date to which interest has been paid or, if no interest
has been paid, from the date of issuance.

                                       75
<PAGE>

   Senior Subordinated Notes. The Senior Subordinated Notes will be unsecured
obligations of Lyondell initially limited in aggregate principal amount to $500
million and will mature on May 1, 2009. Interest on the Senior Subordinated
Notes is 10 7/8% per annum. Interest is payable semi-annually in arrears on May
1 and November 1 of each year, beginning on November 1, 1999, to holders of
record on the immediately preceding April 15 and October 15, respectively.
Interest on the Senior Subordinated Notes will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from the date
of issuance.

   Interest on the new notes will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Principal of and premium, if any, and
interest and liquidated damages, if any, on the new notes will be payable at
the office or agency of Lyondell maintained for this purpose within The City
and The State of New York. Lyondell may opt to pay interest and liquidated
damages, if any, by check mailed to the holders of the new notes at their
respective addresses listed in the register of holders of the new notes. All
payments with respect to Global Notes, whose holders have given wire transfer
instructions on or before the relevant record date to the paying agent, will be
required to be made by wire transfer of immediately available funds to the
accounts specified by the holders. Until otherwise designated by Lyondell,
Lyondell's office or agency in New York will be the office of the relevant
Trustee maintained for this purpose. The new notes will initially be issued in
global form. In the event they are subsequently certificated, the new notes
will be issued in denominations of $1,000 and integral multiples of $1,000.

   Subject to the covenants described below under "--Restrictive Covenants,"
Lyondell may issue additional Series A Senior Secured Notes, additional Series
B Senior Secured Notes and additional Senior Subordinated Notes under the
respective indentures having substantially the same terms in all material
respects as the outstanding notes of each series, as the case may be. However,
the aggregate principal amount of Senior Secured Notes outstanding at any time
will not exceed $1.9 billion. Furthermore, before any issuance of additional
notes, Lyondell must deliver to the Trustee an opinion of counsel confirming
that the holders of the outstanding Series A Senior Secured Notes, Series B
Senior Secured Notes or Senior Subordinated Notes, as the case may be, will be
subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if the additional notes were not
issued. The outstanding Series A Senior Secured Notes, Series B Senior Secured
Notes and Senior Subordinated Notes and any additional Series A Senior Secured
Notes, Series B Senior Secured Notes or Senior Subordinated Notes, as the case
may be, would each be treated as a single class for all purposes under the
relevant indenture.

Security

   The Senior Secured Notes will be secured by a lien equally and ratably with
all Senior Indebtedness owing under the Existing Credit Facility (and, with
respect to some of Lyondell's manufacturing plants described below, equally and
ratably with Existing ARCO Chemical Debt as well) under the security agreements
and pledge agreements, as amended from time to time (collectively, the
"Security Documents"), between Lyondell or some of its Restricted Subsidiaries
and Morgan Guaranty Trust Company of New York, as collateral agent.

   The liens granted under the Security Documents constitute first-priority
liens, with some exceptions and permitted liens described in the documents, on
the following assets:

  . personal property of Lyondell and Lyondell Worldwide;

  . substantially all the stock of Lyondell's domestic subsidiaries directly
    owned by Lyondell or Lyondell Worldwide;

  . 65% of the stock of Lyondell's foreign subsidiaries directly owned by
    Lyondell or Lyondell Worldwide (other than the stock of some subsidiaries
    for which consent is required to permit a pledge to the extent this
    consent has not been obtained);

  . the rights of some of Lyondell's Joint Venture Subsidiaries to receive
    distributions from Joint Ventures in which they hold Equity Interests;
    and

                                       76
<PAGE>

  . mortgages on Lyondell Worldwide facilities located in Bayport, Texas,
    Channelview, Texas and Lake Charles, Louisiana (collectively and together
    with any other assets that may be pledged from time to time, the
    "Collateral").

   Holders of the Senior Secured Notes will be granted a lien equally and
ratably with any lien granted on additional assets to secure the holders of
Senior Indebtedness under the Existing Credit Facility subsequent to the
issuance of the new notes.

   Any or all liens for the benefit of the holders of the Senior Secured Notes
will be automatically released, without the consent of the holders, upon a
release of the lien or liens under the terms of the Security Documents and the
Existing Credit Facility or if the release is approved by the requisite lenders
under the Existing Credit Facility. The Security Documents generally provide
that liens will be automatically released if the assets subject to the liens
are transferred or otherwise disposed of in compliance with the provisions of
the Existing Credit Facility. The Existing Credit Facility specifically
provides that liens will be automatically released from assets that are the
subject of a Major Asset Sale and that are transferred to a Subject Asset
Transferee according to the terms of the Existing Credit Facility.

   In addition, the collateral agent and Lyondell may amend the provisions of
the Security Documents with the consent of the requisite lenders and without
the consent of the holders of the Senior Secured Notes. The lenders under the
Existing Credit Facility will have the sole ability to control remedies
(including upon sale or liquidation after acceleration of the new notes or the
debt under the Existing Credit Facility) with respect to the collateral. The
Senior Secured Note Indentures will provide that Lyondell and its Restricted
Subsidiaries which are party to any Security Documents will comply with all the
covenants and agreements contained in such Security Documents the failure to
comply with which would have a material and adverse effect on the Liens
purported to be created thereby, unless such failure to comply is waived by the
requisite lenders under the Existing Credit facility and, after that waiver,
Lyondell is in compliance with the covenant described under "--Security." See
"Risk Factors--Holders of the Senior Secured Notes may not be able to fully
realize the value of their liens; in such case, holders of the Senior Secured
Notes will have an unsecured claim against Lyondell to the extent that amounts
due on the Senior Secured Notes exceed the proceeds from the sale of the
secured assets."

   From and after the date when all liens granted in favor of the holders of
Senior Indebtedness under the Existing Credit Facility are released, the
provisions regarding security described above will no longer apply. The
provisions of the covenant described below under "--Restrictive Covenants--
Liens--Senior Secured Notes" will, however, continue to apply.

Subsidiary Guarantees

   As of the date of these exchange offers, Lyondell Worldwide and Lyondell
Nederland are the only subsidiary guarantors of the new notes. Any Restricted
Subsidiary that Guarantees or secures the payment of any other Indebtedness of
Lyondell or any of its Restricted Subsidiaries must also Guarantee the payment
of the new notes, with some exceptions described below under "Limitation on
Issuance of Guarantees of Indebtedness by Subsidiaries." Lyondell Worldwide and
Lyondell Nederland will unconditionally guarantee the due and punctual payment
of the principal of and premium, if any, and interest and liquidated damages,
if any, on the new notes, when and as the same will become due and payable,
whether at maturity, upon redemption, by declaration or otherwise (the
"Subsidiary Guarantees").

   The obligations of the Subsidiary Guarantors will be limited so as not to
constitute a fraudulent conveyance under applicable law. The Subsidiary
Guarantees of the Senior Secured Notes will be general senior obligations of
Lyondell Worldwide and Lyondell Nederland, secured to the extent described
under "--Security." The Subsidiary Guarantees of the Senior Subordinated Notes
will be general senior subordinated unsecured obligations of Lyondell Worldwide
and Lyondell Nederland. See "--Subordination of Senior Subordinated Notes."

                                       77
<PAGE>

   No Subsidiary Guarantor may consolidate with or merge with or into (whether
or not the Subsidiary Guarantor is the surviving Person), another corporation,
Person or entity whether or not affiliated with the Subsidiary Guarantor unless
all of the following are true:

  (1) subject to the provisions of the following paragraph, the Person formed
      by or surviving any consolidation or merger, if other than Lyondell or
      a Subsidiary Guarantor, assumes all the obligations of the Subsidiary
      Guarantor under the new notes issued under the applicable indenture;

  (2) immediately after giving effect to the transaction, no Default or Event
      of Default exists; and

  (3) Lyondell would, at the time of the transaction and after giving pro
      forma effect thereto as if the transaction had occurred at the
      beginning of the applicable four-quarter period, both:

    (a) have a Consolidated Net Worth immediately after the transaction
        equal to or greater than the Consolidated Net Worth of Lyondell
        immediately preceding the transaction; and

    (b) except with respect to a consolidation or merger with a Person that
        has no outstanding Indebtedness, be permitted to incur at least
        $1.00 of additional Indebtedness under the Fixed Charge Coverage
        Ratio test stated in the covenant described under the caption "--
        Restrictive Covenants--Incurrence of Indebtedness and Issuance of
        Preferred Stock."

The requirements of conditions (1) and (2) listed above will not apply in the
case of a consolidation with or the merger of a Subsidiary Guarantor with or
into Lyondell and the requirements of condition (3) listed above will not apply
in the case of a consolidation with or the merger of a Subsidiary Guarantor
with or into another Subsidiary Guarantor.

   In the event of a sale or other disposition, by way of merger, consolidation
or otherwise, of all the Capital Stock of any Subsidiary Guarantor to any
Person that is not an Affiliate of Lyondell, the Subsidiary Guarantor will be
released and relieved of any obligations under its Subsidiary Guarantee if the
Net Proceeds of the sale or other disposition are applied in accordance with
the applicable provisions of the applicable indenture. See "Repurchase at the
Option of Holders--Asset Sales."

   Upon the release or discharge of the Guarantee which resulted in the
creation of the Subsidiary Guarantee of the Subsidiary Guarantor or, in the
case of Lyondell Worldwide and Lyondell Nederland, the release or discharge of
its Guarantee of Indebtedness under the Existing Credit Facility, the
Subsidiary Guarantors will be released and relieved of any obligations under
its Subsidiary Guarantee. A Subsidiary Guarantor will not be released and
relieved of its obligations, however, in the event of a discharge or release by
or as a result of payment under the Subsidiary Guarantee.

   Upon the designation of any Subsidiary Guarantor as an Unrestricted
Subsidiary according to the terms of the indentures, the Subsidiary Guarantor
will be released and relieved of any obligations under its Subsidiary
Guarantee. See "Restrictive Covenants--Limitations on Issuances of Guarantees
of Indebtedness by Subsidiaries."

Subordination of Senior Subordinated Notes

   The payment of principal of and premium, if any, and interest on the Senior
Subordinated Notes will be subordinated in right of payment, as stated in the
Senior Subordinated Note Indenture, to the prior payment in full of all Senior
Indebtedness, whether outstanding on or incurred after May 17, 1999.

   If Lyondell fails to make any payment on the Senior Subordinated Notes when
due or within any applicable grace period, whether or not on account of the
payment blockage provision referred to below, the failure will constitute an
Event of Default under the Senior Subordinated Note Indenture and will enable
the holders to accelerate the maturity of the Senior Subordinated Notes. See
"--Events of Default and Remedies."

   The obligations of each Subsidiary Guarantor under its Senior Subordinated
Note Subsidiary Guarantee are unsecured senior subordinated obligations. As
such, the rights of holders of Senior Subordinated Notes to

                                       78
<PAGE>

receive payment by a Subsidiary Guarantor under its Subsidiary Guarantee will
be subordinated in right of payment to the rights of holders of Senior
Indebtedness of that Subsidiary Guarantor, including its Senior Secured Note
Subsidiary Guarantee and its Guarantee of the Existing Credit Facility. The
terms of the subordination provisions described below with respect to
Lyondell's obligations under the Senior Subordinated Notes apply equally to a
Subsidiary Guarantor and the obligations of that Subsidiary Guarantor under its
Senior Subordinated Note Subsidiary Guarantee.

   The terms of the subordination provisions described below will not apply to
payments from money or the proceeds of U.S. Government obligations deposited in
trust before the occurrence of an event prohibiting payment of or on the Senior
Subordinated Notes and held in trust by the Senior Subordinated Note Trustee
for the payment of principal of and interest on the Senior Subordinated Notes
under the provisions described under "--Defeasance."

   Upon any distribution to creditors of Lyondell in a liquidation or
dissolution of Lyondell or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to Lyondell or its property, an
assignment for the benefit of creditors or any marshaling of Lyondell's assets
and liabilities, the holders of Senior Indebtedness will be entitled to receive
payment in full in cash or cash equivalents of all Obligations due in respect
of the Senior Indebtedness before the Holders of Senior Subordinated Notes will
be entitled to receive any payment with respect to the Subordinated Note
Obligations. Until all Obligations with respect to Senior Indebtedness are paid
in full in cash or cash equivalents, any distribution to which the Holders of
Senior Subordinated Notes would be entitled will be made to the holders of
Senior Indebtedness, (except that Holders of Senior Subordinated Notes may
receive and retain Permitted Junior Securities and payments made from the trust
described under "--Defeasance." Payment in full on all obligations that were
due would include interest after the commencement of any proceeding at the rate
specified in the applicable Senior Indebtedness.

   Lyondell also may not make any payment upon or in respect of the
Subordinated Note Obligations, except in Permitted Junior Securities or from
the trust described under "--Defeasance," if:

  . a default in the payment of the principal of, or premium, if any, or
    interest on, or commitment fees relating to, Designated Senior
    Indebtedness occurs and is continuing beyond any applicable period of
    grace; or

  . any other default occurs and is continuing with respect to Designated
    Senior Indebtedness that permits holders of the Designated Senior
    Indebtedness as to which the default relates to accelerate its maturity
    and the Senior Subordinated Note Trustee receives a notice of the default
    (a "Payment Blockage Notice") from Lyondell or the holders of any
    Designated Senior Indebtedness. Payments on the Senior Subordinated Notes
    may and will be resumed including the payment of any amounts previously
    blocked by the Payment Blockage Notice:

    (1) in the case of a payment default, upon the date on which the default
        is cured or waived; and

    (2) in case of a nonpayment default, the earlier of the date on which
        the nonpayment default is cured or waived or 179 days after the date
        on which the applicable Payment Blockage Notice is received, unless
        the maturity of any Designated Senior Indebtedness has been
        accelerated.

   No new period of payment blockage may be commenced unless and until 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Senior Subordinated Note Trustee
will be, or be made, the basis for a subsequent Payment Blockage Notice unless
the default will have been waived or cured for a period of not less than 90
days.

   "Designated Senior Indebtedness" means:

  . the Indebtedness, other than Hedging Obligations, outstanding under the
    Existing Credit Facility; and

  . any other Senior Indebtedness permitted under the Senior Subordinated
    Note Indenture the principal amount of which is $25.0 million or more and
    that has been designated by Lyondell in writing to the Senior
    Subordinated Note Trustee as "Designated Senior Indebtedness."

                                       79
<PAGE>

   "Permitted Junior Securities" means Equity Interests in Lyondell or debt
securities of Lyondell that are subordinated to all Senior Indebtedness, and
any debt securities issued in exchange for Senior Indebtedness, to
substantially the same extent as, or to a greater extent than, the Senior
Subordinated Notes are subordinated to Senior Indebtedness.

   "Senior Indebtedness" means, with respect to any Person:

  . all Obligations of that Person outstanding under the Existing Credit
    Facility and all Hedging Obligations payable to a lender or an Affiliate
    of a lender or to a Person that was a lender or an Affiliate of a lender
    at the time the contract was entered into under the Existing Credit
    Facility, including, without limitation, interest accruing subsequent to
    the filing of, or which would have accrued but for the filing of, a
    petition for bankruptcy, whether or not the interest is an allowable
    claim in the bankruptcy proceeding;

  . any other Indebtedness, unless the instrument under which that
    Indebtedness is incurred expressly provides that it is subordinated in
    right of payment to any other Senior Indebtedness of that Person; and

  . all Obligations with respect to the foregoing.

Notwithstanding anything to the contrary in the foregoing, Senior Indebtedness
will not include:

  . any liability for federal, state, local or other taxes;

  . any Indebtedness of that Person to any of its Subsidiaries or other
    Affiliates;

  . any trade payables;

  . any debt securities and guarantees issued to any trust, partnership or
    other entity affiliated with Lyondell which is a financing vehicle of
    Lyondell in connection with the issuance of preferred securities by the
    financing entity; or

  . any Indebtedness that is incurred in violation of the Senior Subordinated
    Note Indenture.

   "Subordinated Note Obligations" means all Obligations with respect to the
Senior Subordinated Notes, including, without limitation, principal, premium
of, if any, and interest and liquidated damages, if any, payable under the
terms of the Senior Subordinated Notes (including upon the acceleration or
redemption thereof), together with and including any amounts received or
receivable upon the exercise of rights of recision or other rights of action
(including claims for damages) or otherwise.

   The Senior Subordinated Note Indenture will further require that Lyondell
promptly notify holders of Designated Senior Indebtedness if payment of the
Senior Subordinated Notes is accelerated because of an Event of Default. As a
result of the subordination provisions described above, in the event of a
liquidation or insolvency, holders of Senior Subordinated Notes may recover
less ratably than our creditors who are holders of Senior Indebtedness.

Mandatory Redemption

   Except as described below under "--Repurchase at the Option of Holders,"
Lyondell will not be required to make any mandatory redemption or sinking fund
payments with respect to the new notes.

Optional Redemption

 Series A Senior Secured Notes

   We can redeem the Series A Senior Secured Notes, in whole, at any time, or
in part, from time to time, at our option upon not less than 30 nor more than
60 days' notice at a redemption price equal to the make-whole price described
below.

                                       80
<PAGE>

   "Make-Whole Price" means an amount equal to the greater of:

  . 100% of the principal amount of the Series A Senior Secured Notes; and

  . as determined by an Independent Investment Banker (as defined below), the
    sum of the present values of the remaining scheduled payments of
    principal and interest thereon discounted to the date of redemption on a
    semiannual basis (assuming a 360-day year consisting of twelve 30-day
    months) at the Adjusted Treasury Rate (as defined below);

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

   "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for the redemption date, plus 0.5%.

   "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Series A Senior Secured Notes to be redeemed that
would be utilized, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of the Series A Senior Secured Notes.

   "Comparable Treasury Price" means, with respect to any redemption date:

  . the average of the bid and asked prices for the Comparable Treasury Issue
    on the third Business Day preceding the redemption date, as listed in the
    daily statistical release (or any successor release) published by the
    Federal Reserve Bank of New York and designated "Composite 3:30 p.m.
    Quotations for U.S. Government Securities"; or

  . if the release (or any successor release) is not published or does not
    contain the prices on the Business Day:

    (1) the average of the Reference Treasury Dealer Quotations for the
        redemption date after excluding the highest and lowest of the
        Reference Treasury Dealer Quotations; or

    (2) if the Series A Senior Secured Note Trustee obtains fewer than three
        Reference Treasury Dealer Quotations, the average of all the
        quotations.

   "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
Series A Senior Secured Note Trustee, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Series A Senior Secured Note Trustee
by the Treasury Reference Dealer at 5:00 p.m. on the third Business Day
preceding the redemption date.

   "Independent Investment Banker" means a Reference Treasury Dealer appointed
by Lyondell.

   "Reference Treasury Dealer" means a primary U.S. Government securities
dealer in New York City (a "Primary Treasury Dealer") selected by Lyondell.

 Series B Senior Secured Notes

   We cannot redeem the Series B Senior Secured Notes before May 1, 2004.
Thereafter, we may redeem the Series B Senior Secured Notes at our option, in
whole or from time to time in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) described below plus accrued and unpaid interest and liquidated
damages, if any, thereon to the applicable redemption date, if redeemed during
the twelve-month period beginning on May 1 of the following years:

 Senior Subordinated Notes

   Except as provided below, we cannot redeem the Senior Subordinated Notes
before May 1, 2004. Thereafter, we may redeem the Senior Subordinated Notes at
our option, in whole or from time to time in part, upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages
of principal amount) described below plus accrued and unpaid interest and
liquidated damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on May 1 of the following
years:

<TABLE>

      Year                                                            Percentage

      2006...........................................................  101.812%
      2007...........................................................  100.000%
</TABLE>

   Notwithstanding the foregoing, on or before May 1, 2002, we can redeem in
the aggregate up to 35% of the aggregate principal amount of the Senior
Subordinated Notes from time to time originally issued with the net cash
proceeds of one or more Public Equity Offerings, at a redemption price
(expressed as a percentage of principal amount on the redemption date) of
110.875% plus accrued and unpaid interest and liquidated damages, if any, to
the redemption date; provided that:

  . at least 65% of the aggregate principal amount of the Senior Subordinated
    Notes from time to time originally issued under the applicable indenture
    must remain outstanding and be held, directly or indirectly, by Persons
    other than Lyondell and its Affiliates, immediately after each
    redemption; and

  . the redemption occurs within 90 days of the closing of a Public Equity
    Offering.

Selection and Notice

   If less than all the new notes issued under an indenture are to be redeemed
at any time, selection of the applicable new notes for redemption will be made
by the applicable Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the new notes are listed. If the
new notes are not so listed, selection of the applicable new notes for
redemption will be on a pro rata basis, by lot or by a method that the
applicable Trustee deems fair and appropriate. However, no new notes of $1,000
or less will be redeemed in part.

   Notices of redemption will be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each holder of new notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any new note is to be redeemed in part only, the notice of
redemption that relates to the applicable note will state the portion of the
principal amount to be redeemed. A new note in principal amount equal to the
unredeemed portion will be issued in the name of the applicable holder upon
cancellation of the original note. New notes called for redemption become due
on the date fixed for redemption. On and after the redemption date, interest
ceases to accrue on new notes or portions of the new notes called for
redemption.

Repurchase at the Option of Holders

 Change of Control

   Upon the occurrence of a Change of Control, each holder of new notes will
have the right to require us to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of its new notes under the Change of Control
offer described below at an offer price in cash equal to 101% of the aggregate
principal amount plus accrued and unpaid interest and liquidated damages, if
any, to the date of purchase (the "Change of Control Payment") on a date that
is not more than 90 days after the occurrence of the Change of Control (the
"Change of Control Payment Date"). Within 30 days following any Change of
Control, Lyondell or the applicable

                                       82
<PAGE>

Trustee will mail a notice to each holder offering to repurchase the new notes
held by a holder under the procedures specified in the notice. We will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations to the extent those laws and regulations are
applicable in connection with the repurchase of the new notes as a result of a
Change of Control.

   On the Change of Control Payment Date, we will, to the extent lawful:

  . accept for payment all new notes or portions of the new notes properly
    tendered and not withdrawn under the Change of Control offer;

  . deposit with the applicable Paying Agent an amount equal to the Change of
    Control Payment in respect of all new notes or portions thereof so
    tendered; and

  . deliver or cause to be delivered to the applicable Trustee the new notes
    so accepted together with an Officers' Certificate stating the aggregate
    principal amount of new notes or portions of new notes being purchased by
    Lyondell.

   The Paying Agent will promptly mail to each holder of new notes so tendered
the Change of Control Payment for those new notes, and the applicable Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each holder a note equal in principal amount to any unpurchased portion of
the new notes surrendered, if any. However, each note will be in a principal
amount of $1,000 or an integral multiple thereof.

   Before complying with the provisions of this covenant, but in any event
within 90 days following a Change of Control, we must either repay all
outstanding Senior Indebtedness or obtain the requisite consents, if any, under
all agreements governing outstanding Senior Indebtedness, to the extent
necessary, to permit the repurchase of Senior Subordinated Notes required by
this covenant.

   A failure by Lyondell to comply with the provisions of the preceding
paragraphs will constitute an Event of Default under the applicable indenture.
Except as described above with respect to a Change of Control, the indentures
will not contain provisions that permit the holders of the new notes to require
us to purchase or redeem the new notes in the event of a takeover,
recapitalization or similar transaction. See "--Events of Default and
Remedies."

   There can be no assurance that Lyondell will have the financial resources to
purchase the new notes, particularly if a Change of Control triggers a similar
repurchase requirement for, or results in the acceleration of, other
Indebtedness. The Existing Credit Facility provides that some events
constituting a Change of Control will constitute a default under the Existing
Credit Facility and could result in the acceleration of the maturity of the
Existing Credit Facility. Future indebtedness might contain similar provisions.
If a Change of Control occurs, Lyondell could try to refinance the Existing
Credit Facility. If Lyondell does not refinance the Existing Credit Facility,
Lyondell might not be allowed to purchase the Senior Subordinated Notes. As a
result, Lyondell would be in default under the Senior Subordinated Note
Indenture, which would also be a default under the Senior Secured Note
Indenture and the Existing Credit Facility. If this occurs, the subordination
provisions of the Senior Subordinated Note Indenture would restrict payments to
the Senior Subordinated Noteholders. Accordingly, Lyondell might not be able to
fulfill its obligation to repurchase any new notes if a Change of Control
occurs. See "Risk Factors--Lyondell may not be able to repurchase your new
notes upon a change of control."

   Lyondell 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 at the
same or a higher purchase price, at the same times and otherwise in substantial
compliance with the requirements applicable to a Change of Control offer made
by Lyondell and purchases all new notes validly tendered and not withdrawn
under the Change of Control offer.

   "Change of Control" means the occurrence of any of the following:


                                       83
<PAGE>

  . the sale, transfer, conveyance or other disposition, in one or a series
    of related transactions, of all or substantially all the assets of
    Lyondell and its Subsidiaries taken as a whole to any Person or group (as
    the term is used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act)
    other than to a Person or group who, before the transaction, held a
    majority of the voting power of the voting stock of Lyondell;

  . the acquisition by any Person or group (as defined above) of a direct or
    indirect interest in more than 50% of the voting power of the voting
    stock of Lyondell, by way of merger or consolidation or otherwise; or

  . the first day on which a majority of the members of the board of
    directors of Lyondell are not Continuing Directors.

   The phrase "all or substantially all" the assets of Lyondell will likely be
interpreted under applicable state law and will be dependent upon particular
facts and circumstances. As a result, there may be a degree of uncertainty in
ascertaining whether a sale or transfer of "all or substantially all" the
assets of Lyondell has occurred, in which case a holder's ability to obtain
the benefit of a Change of Control offer may be impaired.

 Asset Sales

   We cannot, and cannot permit any of our Restricted Subsidiaries to,
consummate an Asset Sale unless:

  . Lyondell and/or the Restricted Subsidiary, as the case may be, receives
    consideration at the time of the Asset Sale at least equal to the fair
    market value (as conclusively evidenced by a resolution of the board of
    directors of Lyondell listed in an Officers' Certificate delivered to the
    Trustees) of the assets or Equity Interests issued or sold or otherwise
    disposed of; and

  . at least 80% of the consideration therefor received by Lyondell and/or
    the Restricted Subsidiary is in the form of:

    (1) cash or Cash Equivalents; or

    (2) a controlling interest or a joint venture interest (to the extent
        otherwise permitted by the indentures) in a business engaged in a
        Permitted Business or long-term property or assets that are used or
        useful in a Permitted Business.

However, the amount of (x) any liabilities as shown on Lyondell's or the
Restricted Subsidiary's most recent balance sheet of Lyondell or any
Restricted Subsidiary, other than contingent liabilities and liabilities that
are by their terms subordinated to the new notes or any guarantee of the new
notes, that are assumed by the transferee of any assets under a customary
novation agreement that releases Lyondell or the Restricted Subsidiary from
further liability and (y) any securities, notes or other obligations received
by Lyondell or any Restricted Subsidiary from the transferee that are promptly
converted by Lyondell or the Restricted Subsidiary into cash (to the extent of
the cash received) will be deemed to be cash for purposes of this provision.

   Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
Lyondell may apply the Net Proceeds, at its option either to:

  (1) permanently repay Senior Indebtedness and correspondingly reduce
      commitments with respect thereto in the case of revolving borrowings of
      Lyondell or a Subsidiary Guarantor or repay Indebtedness and
      correspondingly reduce commitments with respect thereto in the case of
      revolving borrowings of any Restricted Subsidiary that is not a
      Subsidiary Guarantor. However, the Senior Secured Notes Indenture will
      provide that, so long as the Senior Secured Notes are secured, only
      repayment of Senior Indebtedness incurred under the Existing Credit
      Facility, but not any refinancing of this debt other than a credit
      facility with commercial banks and other lenders, or the 9.9%
      Debentures due 2000 of ARCO Chemical will constitute a repayment of
      Indebtedness permitted under this clause (1); or


                                      84
<PAGE>

  (2) acquire a controlling interest or a joint venture interest to the
      extent otherwise permitted by the Indentures in another business or,
      the making of a capital expenditure or the acquisition of other long-
      term assets, in each case, in a Permitted Business or enter into a
      binding commitment for any expenditure or acquisition; provided that
      the binding commitment will be treated as a permitted application of
      Net Proceeds from the date of the commitment until and only until the
      earlier of (x) the date on which the expenditure or acquisition is
      consummated and (y) the 180th day following the expiration of the
      aforementioned 360 day period. If the expenditure or acquisition
      contemplated by the binding commitment is not consummated on or before
      the 180th day and Lyondell has not applied the Net Proceeds under
      clause (1) above on or before the 180th day, the commitment will be
      deemed not to have been a permitted application of Net Proceeds at any
      time.

However, the Senior Secured Note Indentures will provide that, so long as the
Senior Secured Notes are secured, Lyondell may not apply Net Proceeds of a
Significant Asset Sale under option (2) above to satisfy its obligations under
the first sentence of this paragraph except to the extent that the provisions
of the Existing Credit Facility (but not any refinancing thereof other than a
credit facility with commercial banks and other lenders) require a mandatory
prepayment from the proceeds but the requisite lenders have waived mandatory
prepayment. Pending the final application of any Net Proceeds, Lyondell may
temporarily reduce the revolving Indebtedness under the Existing Credit
Facility or otherwise invest the Net Proceeds in any manner that is not
prohibited by the indentures.

Any Net Proceeds from Asset Sales that are not applied or invested as provided
above will be deemed to constitute "Excess Proceeds." When the aggregate amount
of Excess Proceeds under an indenture exceeds $25 million, Lyondell will be
required to make an offer to all holders of new notes issued under the
applicable indenture (an "Asset Sale Offer") to purchase the maximum principal
amount of new notes and if Lyondell:

  . is required to do so under the terms of any other Indebtedness ranking
    pari passu with the new notes, to purchase the other Indebtedness; and

  . elects to do so, to purchase any Existing ARCO Chemical Debt, on a pro
    rata basis with the new notes, that may be purchased out of the Excess
    Proceeds, at an offer price in cash in an amount equal to 100% of the
    principal amount thereof plus accrued and unpaid interest and liquidated
    damages, if any, thereon to the date of purchase, in accordance with the
    procedures described in the applicable indenture.

The Senior Subordinated Note Indenture will provide that, before complying with
the provisions of this covenant, we must either repay all outstanding Senior
Indebtedness or obtain the requisite consents, if any, under all agreements
governing outstanding Senior Indebtedness, to the extent necessary, to permit
the repurchase of Senior Subordinated Notes required by this covenant. To the
extent that the aggregate amount of Senior Secured Notes and Senior
Subordinated Notes, and, in each case, any other pari passu Indebtedness
subject to the Asset Sale Offer, tendered under the Asset Sale Offer is less
than the Excess Proceeds, we may, subject to the other terms of the indentures,
use any remaining Excess Proceeds for general corporate purposes. If the
aggregate principal amount of new notes surrendered by holders thereof in
connection with any Asset Sale Offer exceeds the amount of Excess Proceeds, the
Trustee will select the new notes to be purchased on a pro rata basis. Upon
completion of the offer to purchase made under each indenture, the amount of
Excess Proceeds under the applicable indenture will be reset at zero.

  (3) make any principal payment on, or purchase, redeem, defease or
      otherwise acquire or retire for value any Indebtedness ("Subordinated
      Debt") of Lyondell or any Restricted Subsidiary that is subordinated by

      interest or principal at Stated Maturity; or

  (4) make any Restricted Investment (all the payments and other actions
      described in clauses (1) through (4) being collectively referred to as
      "Restricted Payments");

unless, at the time of and after giving effect to the Restricted Payment:

  (a) no Default or Event of Default will have occurred and be continuing
      after giving effect to the Restricted Payment;

  (b) Lyondell would, at the time of the Restricted Payment and after giving
      pro forma effect to the Restricted Payment as if the Restricted Payment
      had been made at the beginning of the most recently ended four full
      fiscal quarters for which financial statements have been filed with the
      SEC under the covenant described below under the caption "--Reports"
      immediately preceding the date of the Restricted Payment, have been
      permitted to incur at least $1.00 of additional Indebtedness under the
      Fixed Charge Coverage Ratio test described in the first paragraph of
      the covenant in the applicable indenture described below under the
      caption "--Incurrence of Indebtedness and Issuance of Preferred Stock";

      after May 17, 1999, excluding Restricted Payments permitted by clauses
      (b) to the extent paid to Lyondell or any of its Restricted
      Subsidiaries or to the extent the distributions are deducted as a
      minority interest in calculating Consolidated Net Income, (c), (d),
      (e), (g), (j), (n) and (p) of the next succeeding paragraph and 50% of
      any Restricted Payments permitted by clause (h) of the next succeeding
      paragraph, is less than the sum, without duplication, of:

    (1) 50% of the Consolidated Net Income of Lyondell for the period (taken
        as one accounting period) from the beginning of the first fiscal
        quarter commencing on April 1, 1999 to the end of Lyondell's most
        recently ended fiscal quarter for which financial statements have
        been filed with the SEC under the covenant described below under the
        caption "--Reports" at the time of the Restricted Payment or, if the
        Consolidated Net Income for the period is a deficit, less 100% of
        the deficit, plus

    (2) 100% of the aggregate net cash proceeds received by Lyondell or any
        of its Restricted Subsidiaries from the issue or sale, other than to
        a Subsidiary or Joint Venture of Lyondell, after May 17, 1999 of
        Qualified Equity Interests of Lyondell or of debt securities of
        Lyondell or any of its Restricted Subsidiaries that have been
        converted into or exchanged for Qualified Equity Interests of
        Lyondell, plus

    (3) to the extent that any Restricted Investment other than a Restricted
        Investment permitted to be made under clauses (g) or (h) below that
        was made after May 17, 1999 is sold for cash or otherwise
        liquidated, repaid or otherwise reduced, including by way of
        dividend, to the extent not included in calculating Consolidated Net
        Income, the lesser of (A) the cash return with respect to the
        Restricted Investment (less the cost of disposition, if any) and (B)
        the initial amount of the Restricted Investment, plus

                                      86
<PAGE>

    (4) an amount equal to the sum of:

      (A) the net reduction in Investments in Unrestricted Subsidiaries
          resulting from dividends, repayments of loans or other transfers
          of assets to the extent not included in calculating Consolidated
          Net Income, in each case to Lyondell or any Restricted
          Subsidiary from Unrestricted Subsidiaries; and

      (B) the portion proportionate to Lyondell's equity interest in the
          Subsidiary of the fair market value of the net assets of an
          Unrestricted Subsidiary at the time the Unrestricted Subsidiary
          is designated a Restricted Subsidiary;

    provided, however, that the foregoing sum will not exceed, in the case
    of any Unrestricted Subsidiary, the amount of Restricted Investments,
    other than Restricted Investments permitted to be made under clauses
    (g) or (h) below, previously made after May 17, 1999 by Lyondell or any
    Restricted Subsidiary in the Unrestricted Subsidiary.

   The amount of any Restricted Payment, if other than cash, will be the fair
market value (as conclusively evidenced by a resolution of the board of
directors) of the asset(s) proposed to be transferred by Lyondell or the
Restricted Subsidiary, as the case may be, under the Restricted Payment.

   If, other than with respect to payments made under clauses (a) and (n)
below, no Default or Event of Default will have occurred and be continuing
after giving effect to the Restricted Payment, the foregoing provisions will
not prohibit the following Restricted Payments:

  (a) the payment of any dividend within 60 days after the date of the
      dividend declaration, if at said date of declaration the payment would
      have complied with the provisions of the applicable indenture;

        to Lyondell; provided that at least 50% of the class of Capital
        Stock is held by Lyondell and/or one or more of its Restricted
        Subsidiaries; or

        Stock";

  (c) the payment of cash dividends on any series of Disqualified Stock

      Disqualified Stock;

  (d) the redemption, repurchase, retirement or other acquisition of any
      Equity Interests of Lyondell, any Restricted Subsidiary or any Joint
      Venture, or the acquisition of all the outstanding Equity Interests of

      other than the ownership of Equity Interests in a Joint Venture, in
      exchange for, or out of the net cash proceeds of the substantially
      concurrent sale (other than to a Subsidiary or Joint Venture of
      Lyondell) of, Qualified Equity Interests of Lyondell; provided that the
      amount of any net cash proceeds that are utilized for any redemption,

      Lyondell) of Qualified Equity Interests of Lyondell; provided that the
      amount of any net cash proceeds that are utilized for any redemption,
      repurchase, retirement or other acquisition will be excluded from
      clause (c)(2) of the preceding paragraph;

  (f) the repurchase, redemption or other acquisition or retirement for value
      of (i) any Equity Interests of Lyondell or any Subsidiary of Lyondell
      held by any member of Lyondell's or any of its

                                       87

     under employee or director benefit plans of Lyondell or any Subsidiary
     of Lyondell; provided that the aggregate price paid for all the
     repurchased, redeemed, acquired or retired Equity Interests will not
     exceed $5.0 million in any fiscal year of Lyondell;

  (g) Restricted Investments in any of the Specified Joint Ventures,
      including without limitation, the purchase of Equity Interests of a
      Specified Joint Venture directly from another Person or the purchase of
      all the outstanding Equity Interests of any Person that conducts no
      operations and has no assets or liabilities other than the ownership of
      Equity Interests of a Specified Joint Venture, to the extent that the
      proceeds of these investments are used to purchase or redeem an
      interest of another Person in the Specified Joint Venture other than
      Lyondell, a Restricted Subsidiary or an Affiliate of Lyondell, except a
      Person that is deemed to be an Affiliate solely by virtue of its
      ownership of Equity Interests of Lyondell acquired in exchange for
      Equity Interests in the Specified Joint Venture; provided that after
      giving pro forma effect thereto as if the Restricted Payment and any
      related incurrence of Indebtedness had been made at the beginning of
      the most recently ended four full fiscal quarter period for which
      financial statements have been filed with the SEC under the covenant
      described below under the caption "--Reports" immediately preceding the
      date of the Restricted Payment, Lyondell would have been permitted to
      incur at least $1.00 of additional Indebtedness under the Fixed Charge

       plus the number of shares issued in that offering; plus

         (y) if Lyondell issues shares of its common stock after May 17,
       1999, to the extent (1) the shares are issued in exchange for or (2)
       the net cash proceeds therefrom are used substantially concurrently
       to acquire Equity Interests of a Specified Joint Venture held by a
       Person other than Lyondell, a Restricted Subsidiary or an Affiliate
       of Lyondell, except a Person that is deemed to be an Affiliate solely
       by virtue of its ownership of Equity Interests of Lyondell acquired
       in exchange for Equity Interests in the Specified Joint Venture, that
       immediately before the issuance was or as a result of the exchange or

       or issuable during any fiscal year of Lyondell will not exceed
       1,000,000;

      Repurchase at the Option of the Holders--Change of Control" or (y) an
      Asset Sale under a provision no more favorable to the holders thereof
      than the provision of the applicable indenture described under "--
      Repurchase at the Option of the Holders--Asset Sales"; provided that,
      in each case, before the repurchase Lyondell has made a Change of
      Control offer or Asset Sale Offer, as applicable, and repurchased all
      new notes issued under the applicable indenture that were validly
      tendered for payment in connection with the Change of Control offer or
      Asset Sale Offer;

  (n) distributions by any Restricted Subsidiary or Joint Venture of
      chemicals to a holder of Capital Stock of the Restricted Subsidiary or
      Joint Venture if the distributions are made under a provision in a
      joint venture agreement or other arrangement entered into in connection
      with the establishment of the Joint Venture or Restricted Subsidiary
      that requires the holder to pay a price for the chemicals equal to that

      to any subsequent reduction in the amount of any Investments made under
      this clause (o) as a result of the repayment or other disposition
      thereof for cash as described in clause (3) of the first paragraph
      above, the amount of the reduction not to exceed the amount of the
      Investments previously made under this clause (o)); and

  (p) dividends or distributions by any Joint Venture other than a Specified
      Joint Venture to all holders of a class of Capital Stock of the Joint
      Venture permitted by clause (b)(1) above; provided that after giving
      effect to the dividends or distributions and any related transactions,
      the Joint Venture making the dividends or distributions to the holders
      is contractually entitled to receive, and receives within 180 days
      before or after the date of the dividends or distributions, directly or
      indirectly, an equivalent or larger cash payment from each holder,
      other than from a holder that is Lyondell or any Restricted

                                      89
<PAGE>

     Subsidiary, or from an Affiliate of the holder, which cash payment has
     not been previously applied under this clause (p) to offset any other
     dividend or distribution by the Joint Venture to the holder and (y) the
     dividends or distributions do not exceed the holders' pro rata share of
     the Joint Venture's cash flows from operating activities, minus any non-
     cash charge to the extent that it represents an accrual of or reserve
     for cash expenditures in any future period or amortization of a prepaid
     cash expense in any future period.

   The board of directors of Lyondell may designate any Restricted Subsidiary
to be an Unrestricted Subsidiary if this designation would not cause a
Default. For purposes of making this determination, all outstanding
Investments by Lyondell and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of the
designation and will reduce the amount available for Restricted Payments under
the first paragraph of this covenant, except to the extent the Investments
were repaid in cash, and, in the case of a Joint Venture and any Subsidiary of
a Joint Venture designated as an Unrestricted Subsidiary on the first day that
it is a Subsidiary of Lyondell, and except to the extent that either:

  . the Investments were made after May 17, 1999; or

  . in the case of a Specified Joint Venture, the Investments were made
    before May 17, 1999.

All outstanding Investments deemed to be Restricted Payments as described in
the preceding sentence will be deemed to constitute Investments in an amount
equal to the fair market value of the Investments at the time of the
designation (as conclusively determined by the board of directors). The
designation will only be permitted if any Restricted Payment would be
permitted at the time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. In the case of any designation by
Lyondell of a Person as an Unrestricted Subsidiary on the first day that the
Person is a Subsidiary of Lyondell in accordance with the provisions of the
indentures, the designation will be deemed to have occurred for all purposes
of the indentures simultaneously with, and automatically upon, the Person
becoming a Subsidiary.

   Not later than the date of making any Restricted Payment, other than those
permitted by clauses (b)(1), (f), (j) and (n) above, and not later than the
120th day after making any Restricted Payment permitted by clause (f) above,
Lyondell will deliver to the Trustee an Officers' Certificate stating that the
Restricted Payment is permitted and stating the basis upon which the
calculations required by the covenant described under the caption "--
Restricted Payments" were computed.

 Incurrence of Indebtedness and Issuance of Preferred Stock

   On or after May 17, 1999:

  . Lyondell will not, and will not permit any of its Restricted Subsidiaries
    to, directly or indirectly, create, incur, issue, assume, Guarantee or
    otherwise become directly or indirectly liable, contingently or
    otherwise, with respect to (collectively, "incur") any Indebtedness
    (including Acquired Debt);

  . Lyondell will not, and will not permit any of its Restricted Subsidiaries
    to, issue any Disqualified Stock, including Acquired Disqualified Stock;
    and

  . Lyondell will not permit any of its Restricted Subsidiaries that are not
    Subsidiary Guarantors to issue any shares of Preferred Stock, including
    Acquired Preferred Stock;

provided, however, that Lyondell and the Subsidiary Guarantors may incur
Indebtedness, including Acquired Debt, and may issue shares of Disqualified
Stock, including Acquired Disqualified Stock, if the Fixed Charge Coverage
Ratio for Lyondell's most recently ended four full fiscal quarters for which
financial statements have been filed with the SEC under the covenant described
below under the caption "--Reports" immediately preceding the date on which
the additional Indebtedness is incurred or the Disqualified Stock is issued
would have been at least 2.0 to 1, determined on a pro forma basis (including
a pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the Disqualified Stock had been issued, as
the case may be, at the beginning of the four-quarter period. Letters of
credit and bankers'

acceptances will be deemed to have an aggregate principal amount of
Indebtedness equal to the maximum amount available under these instruments.

   The foregoing provisions will not apply to:

  (a) the incurrence by Lyondell of Indebtedness under the Existing Credit
      Facility and by its Subsidiaries under Guarantees of the Existing
      Credit Facility thereof in an aggregate principal amount at any time
      outstanding not to exceed an amount equal to $3.87 billion less the
      aggregate amount of all mandatory repayments, other than mandatory
      prepayments triggered solely by the issuance of Indebtedness or
      Preferred Stock of a Finance Subsidiary to refinance the Existing
      Credit Facility, applied to:

    (1) repay loans outstanding, other than revolving credit loans; or

    (2) permanently reduce the revolving credit commitments;

  (b) the incurrence by Lyondell and the Subsidiary Guarantors of
      Indebtedness represented by the Senior Secured Notes, the Senior
      Subordinated Notes and the Subsidiary Guarantees;

  (c) the incurrence by Lyondell and its Restricted Subsidiaries of Existing
      Indebtedness other than Indebtedness of the type described in clauses
      (a), (b) or (e) through (l) of this covenant;

  (d) the incurrence by Lyondell or any of its Restricted Subsidiaries of any
      Permitted Refinancing in exchange for, or the net proceeds of which are
      used to extend, refinance, renew, replace, defease or refund,
      Indebtedness that was permitted to be incurred under the Fixed Charge
      Coverage Ratio test described above or clauses (b) or (c) above or (m)
      or (n) below or this clause (d);

  (e) the incurrence by Lyondell or any of its Restricted Subsidiaries of
      intercompany Indebtedness between or among Lyondell and any of its
      Restricted Subsidiaries; provided, however, that:

    (1) if Lyondell or any Subsidiary Guarantor is the obligor on the
        Indebtedness, the Indebtedness is expressly subordinated to the
        prior payment in full in cash of all Obligations with respect to
        the new notes or the Subsidiary Guarantee, as the case may be; and

    (2)A.  any subsequent issuance or transfer of Equity Interests that
           results in any Indebtedness being held by a Person other than
           Lyondell or a Restricted Subsidiary; and

      B. any sale or other transfer of any Indebtedness to a Person that
         is not either Lyondell or a Restricted Subsidiary;

    will be deemed, in each case, to constitute an incurrence of
    Indebtedness by Lyondell or the Restricted Subsidiary, as the case may
    be;

  (f) the incurrence by Lyondell or any Restricted Subsidiary of Hedging
      Obligations that are incurred for the purpose of:

    (1) fixing or hedging interest rate or currency risk with respect to
        any fixed or floating rate Indebtedness that is permitted by the
        applicable indenture to be outstanding or any receivable or
        liability the payment of which is determined by reference to a
        foreign currency; provided that the notional principal amount of
        any Hedging Obligation does not exceed the principal amount of the
        Indebtedness to which the Hedging Obligation relates; or

    (2) fixing or hedging risk with respect to fluctuations in the cost of
        raw materials; provided that the obligation is entered into for
        valid business purposes other than speculative purposes, as
        determined by Lyondell's or the Restricted Subsidiary's principal
        financial officer in the exercise of his or her good faith business
        judgment;

  (g) the issuance by any of Lyondell's Restricted Subsidiaries of shares of
      Preferred Stock to Lyondell or a Wholly Owned Restricted Subsidiary;
      provided that:

    (1) any subsequent issuance or transfer of Equity Interests that
        results in the Preferred Stock being held by a Person other than
        Lyondell or a Wholly Owned Restricted Subsidiary; or

                                       91
<PAGE>

    (2) the transfer or other disposition by Lyondell or a Wholly Owned
        Restricted Subsidiary of any shares to a Person other than Lyondell
        or a Wholly Owned Restricted Subsidiary will be deemed, in each
        case, to constitute an issuance of Preferred Stock by the
        Subsidiary on the date that is not permitted by this clause (g);

  (h) the incurrence by Lyondell or any of its Restricted Subsidiaries of
      Indebtedness represented by tender, bid, performance, government
      contract, surety or appeal bonds, standby letters of credit and
      warranty and contractual service obligations of like nature, trade
      letters of credit or documentary letters of credit, in each case to the
      extent incurred in the ordinary course of business of Lyondell or the
      Restricted Subsidiary and the incurrence by Lyondell of Indebtedness
      represented by letters of credit incurred in connection with the PBGC
      Settlement;

  (i) the incurrence by any Restricted Subsidiary of Lyondell of Indebtedness
      or the issuance by any Restricted Subsidiary of Preferred Stock, the
      aggregate principal amount or liquidation preference of which, together
      with all other Indebtedness and Preferred Stock of Lyondell's
      Restricted Subsidiaries at the time outstanding and incurred or issued
      in reliance upon this clause (i), does not exceed $50 million;

  (j) the issuance by any Finance Subsidiary of Preferred Stock with an
      aggregate liquidation preference not exceeding the amount of
      Indebtedness of Lyondell held by the Finance Subsidiary; provided that
      the Fixed Charge Coverage Ratio for Lyondell's most recently ended four
      full fiscal quarters for which financial statements have been filed
      with the SEC under the covenant described below under the caption "--
      Reports" immediately preceding the date on which the Preferred Stock is
      issued would have been at least 2.0 to 1.0, determined on a pro forma
      basis (including a pro forma application of the net proceeds therefrom)
      as if the Preferred Stock had been issued at the beginning of the four-
      quarter period;

  (k) the incurrence of Indebtedness by Foreign Subsidiaries in an aggregate
      principal amount (or accreted value, as applicable) at any time
      outstanding and incurred in reliance upon this clause (k) not to exceed
      $100 million;

  (l) the Guarantee by any Restricted Subsidiary of Indebtedness of Lyondell
      or a Restricted Subsidiary that was permitted to be incurred by another
      provision of this covenant;

  (m) Acquired Debt or Acquired Disqualified Stock; provided that the
      Indebtedness or Disqualified Stock was not incurred in connection with
      or in contemplation of the Person becoming a Restricted Subsidiary; and
      provided further that immediately after giving effect to the
      incurrence, the Fixed Charge Coverage Ratio for Lyondell's most
      recently ended four full fiscal quarters for which financial statements
      have been filed with the SEC under the covenant described below under
      the caption "--Reports" immediately preceding the date of the
      incurrence would have been at least 2.0 to 1.0, determined on a pro
      forma basis;

  (n) Indebtedness or Disqualified Stock of a Specified Joint Venture or a
      Subsidiary thereof existing at the time the Specified Joint Venture
      first becomes a Restricted Subsidiary; provided that the Indebtedness
      or Disqualified Stock was not incurred in connection with or in
      contemplation of the Specified Joint Venture becoming a Restricted
      Subsidiary; and provided further that immediately after giving effect
      to the Specified Joint Venture becoming a Restricted Subsidiary, the
      Fixed Charge Coverage Ratio for Lyondell's most recently ended four
      full fiscal quarters for which financial statements have been filed
      with the SEC under the covenant described below under the caption "--
      Reports" immediately preceding the date on which the Specified Joint
      Venture became a Restricted Subsidiary would have been, determined on a
      pro forma basis:

    (i) at least 2.0 to 1.0; or

    (ii) equal to or greater than it was immediately before the Specified
         Joint Venture becoming a Restricted Subsidiary;


                                       92
<PAGE>

  (o) with respect to any Specified Joint Venture that becomes a Restricted
      Subsidiary, the incurrence by that Specified Joint Venture of
      Indebtedness under any revolving credit facility in an aggregate
      principal amount at any time outstanding not to exceed the aggregate
      principal amount of committed financing under all revolving credit
      facilities of the Specified Joint Venture as in effect on May 17, 1999;
      and

  (p) the incurrence by Lyondell or any Subsidiary Guarantor of Indebtedness
      in an aggregate principal amount or accreted value, as applicable, at
      any time outstanding and incurred in reliance on this clause (p) not to
      exceed $25 million.

   For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness or Preferred Stock meets the criteria of more than one
of the categories of permitted Indebtedness described in clauses (a) through
(p) above or is entitled to be incurred under the first paragraph of this
covenant, Lyondell will, in its sole discretion, classify the item of
Indebtedness or Preferred Stock in any matter that complies with this covenant
and the Indebtedness or Preferred Stock will be treated as having been incurred
under the clauses or the first paragraph hereof, as the case may be, designated
by Lyondell. The amount of Indebtedness issued at a price which is less than
the principal amount of the Indebtedness will be equal to the amount of the
liability in respect of the Indebtedness determined in accordance with GAAP.

 Liens

   Senior Secured Notes

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, assume or suffer to exist any Lien,
except Permitted Liens, on any asset now owned or hereafter acquired, or any
income or profits therefrom, unless all payments due under the Senior Secured
Note Indentures and the Senior Secured Notes or the Senior Secured Note
Guarantees are secured on an equal and ratable basis with the obligations so
secured or, if the obligations are subordinated by their terms to the Senior
Secured Notes or the Senior Secured Note Guarantees, before the obligations so
secured, until such time as the obligations are no longer so secured.

   Senior Subordinated Notes

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, assume or suffer to exist any Lien,
except Permitted Liens, to secure Indebtedness or other obligations that are
pari passu with or subordinated by their terms in right of payment to the
Senior Subordinated Notes or the Senior Subordinated Note Guarantees on any
asset now owned or hereafter acquired, or any income or profits therefrom,
unless all payments due under the Senior Subordinated Note Indenture and the
Senior Subordinated Notes or the Senior Subordinated Note Guarantees are
secured on an equal and ratable basis with the obligations so secured or, if
the obligations are subordinated by their terms to the Senior Subordinated
Notes or the Senior Subordinated Note Guarantees, before the obligations so
secured, until such time as the obligations are no longer so secured.

 Dividend and Other Payment Restrictions Affecting Subsidiaries and Joint
 Ventures

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any restriction on the ability of any Restricted Subsidiary
to:

  (a)(1) pay dividends or make any other distributions to Lyondell or any of
         its Restricted Subsidiaries on its Capital Stock, or with respect to
         any other interest or participation in, or measured by, its profits;
         or

    (2) pay any Indebtedness owed to Lyondell or any of its Restricted
        Subsidiaries;


                                       93
<PAGE>

         Subsidiaries; or

  (c)transfer any of its properties or assets to Lyondell or any of its
         Restricted Subsidiaries;

except for those restrictions existing under or by reason of:

    (1) existing agreements as in effect on May 17, 1999;

    (2) Indebtedness permitted by the indentures to be incurred containing
        restrictions on the ability of Restricted Subsidiaries to
        consummate transactions of the types described in clauses (a), (b)
        or (c) above not materially more restrictive than those contained
        in the indentures;

    (3) the indentures;

    (4) applicable law;

    (5) existing restrictions with respect to a Person acquired by Lyondell
        or any of its Restricted Subsidiaries, except to the extent the
        restrictions were put in place in connection with or in
        contemplation of the acquisition, which restrictions are not
        applicable to any Person, or the properties or assets of any
        Person, other than the Person, or the property or assets of the
        Person, so acquired;

    (6) customary non-assignment provisions in leases and other agreements
        entered into in the ordinary course of business;

    (7) construction loans and purchase money obligations (including
        Capital Lease Obligations) for property acquired in the ordinary
        course of business that impose restrictions of the nature described
        in clause (c) above on the property so constructed or acquired;

    (8) in the case of clause (c) above, restrictions contained in security
        agreements or mortgages securing Indebtedness of a Restricted
        Subsidiary to the extent the restrictions restrict the transfer of
        the property subject to the security agreements or mortgages;

    (9) a Permitted Refinancing, provided that the restrictions contained
        in the agreements governing the Permitted Refinancing are not
        materially more restrictive, taken as a whole, than those contained
        in the agreements governing the Indebtedness being refinanced (as
        conclusively evidenced by a resolution of the board of directors);

    (10) customary restrictions on a Finance Subsidiary imposed in the
         Finance Subsidiary's organizational documents or by the terms of
         its Preferred Stock;

    (11) any restriction with respect to shares of Capital Stock of a
         Restricted Subsidiary imposed under an agreement entered into for
         the sale or disposition of the shares of Capital Stock or any
         restriction with respect to the assets of a Restricted Subsidiary
         imposed under an agreement entered into for the sale or
         disposition of the assets or all or substantially all the Capital
         Stock of the Restricted Subsidiary pending the closing of the sale
         or disposition;

    (12) in the case of any Restricted Subsidiary that is a Joint Venture,
         customary restrictions on the Restricted Subsidiary contained in
         its joint venture agreement, which restrictions are consistent
         with the past practice of Lyondell and its Restricted Subsidiaries
         (as conclusively evidenced by a resolution of the board of
         directors);

    (13) existing restrictions with respect to a Specified Joint Venture or
         the property or assets of the Specified Joint Venture or a
         Subsidiary of a Specified Joint Venture or the property or assets
         of the Subsidiary, in each case, at the time the Specified Joint
         Venture first becomes a Restricted Subsidiary, except to the
         extent the restrictions were put in place in connection with or in
         contemplation of the Specified Joint Venture becoming a Restricted
         Subsidiary, which restrictions are not applicable to any Person,
         or the properties or assets of any Person, other than

                                       94
<PAGE>

       the Specified Joint Venture or the property or assets of the
       Specified Joint Venture or a Subsidiary of the Specified Joint
       Venture or the property or assets of the Subsidiary; and

    (14) the Existing Credit Facility and related documentation as the same
         is in effect on May 17, 1999 and as amended, modified, extended,
         renewed, refunded, refinanced, restated or replaced from time to
         time; provided that the Existing Credit Facility and related
         documentation as so amended, modified, extended, reviewed,
         refunded, refinanced, restated or replaced is not materially more
         restrictive, taken as a whole, as to the matters enumerated above
         than the Existing Credit Facility and related documentation as in
         effect on May 17, 1999 (as conclusively evidenced by a resolution
         of the board of directors).

   For purposes of determining compliance with this covenant, in the event that
a restriction meets the criteria of more than one of the categories of
permitted restrictions described in clauses (1) through (14) above, Lyondell
will, in its sole discretion, classify the restriction in any matter that
complies with this covenant and the restriction will be treated as existing
under the clauses designated by Lyondell.

   In addition, Lyondell will use its best efforts consistent with its
contractual obligations and fiduciary duties to any Joint Venture, in each
case, as in effect on May 17, 1999 not to permit any of its Joint Ventures that
are not Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any restriction on the ability of
the Joint Venture to:

  (a)(1) pay dividends or make any other distributions to Lyondell or any of
         its Restricted Subsidiaries on its Capital Stock or with respect to
         any other interest or participation in, or measured by, its profits;
         or

    (2) pay any Indebtedness owed to Lyondell or any of its Restricted
        Subsidiaries;

  (b) make loans or advances to Lyondell or any of its Restricted
      Subsidiaries; or

   (c) transfer any of its properties or assets to Lyondell or any of its
Restricted Subsidiaries;

except for those restrictions existing under or by reason of:

  (a) the Joint Venture's joint venture agreement or its credit facility
      (provided that in each case the restrictions are consistent with the
      past practice of Lyondell);

  (b) in the case of any Joint Venture existing on May 17, 1999, its existing
      agreements as in effect on the date of the applicable indenture and as
      amended, modified, extended, restated or replaced from time to time;
      provided that no amendment, modification, extension, restatement or
      replacement results in agreements that are materially more restrictive,
      taken as a whole, as to the matters enumerated above than the existing
      agreements as in effect on the date of the applicable indenture (as
      conclusively evidenced by a resolution of the board of directors);

  (c) in the case of LYONDELL-CITGO Refining, any instrument governing its
      Indebtedness; and

  (d) the restrictions described in clauses (4), (5), (6), (7), (8), (10),
      (11) and (14) of the first sentence of this covenant (assuming that
      references in clauses (8) and (11) to Restricted Subsidiary were
      references to a Joint Venture).

 Sale and Leaseback Transactions

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, enter into any Sale and Leaseback Transaction; provided that Lyondell or
any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

  (a) Lyondell or the Restricted Subsidiary, as the case may be, could have:

    (1) incurred Indebtedness in an amount equal to the Attributable Debt
        relating to the Sale and Leaseback Transaction under the Fixed
        Charge Coverage Ratio test described in the first

                                       95
<PAGE>

       paragraph of the covenant described under the caption "--Incurrence
       of Indebtedness and Issuance of Preferred Stock" (whether or not the
       covenant has ceased to be otherwise in effect as described below
       under "Limitation on Applicability of Covenants in Notes Rated
       Investment Grade"); and

    (2) incurred a Lien to secure such Indebtedness under the covenant
        described under the caption "--Liens" without securing the new
        notes; and

  (b) the gross cash proceeds of the Sale and Leaseback Transaction are at
      least equal to the fair market value (as conclusively determined by the
      board of directors) of the property that is the subject of the Sale and
      Leaseback Transaction.

 Line of Business

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, engage in any business other than Permitted Businesses, except to the
extent as would not be material to Lyondell and its Subsidiaries taken as a
whole.

 Merger, Consolidation or Sale of Assets

   Lyondell may not consolidate or merge with or into, whether or not Lyondell
is the surviving corporation, or sell, assign, transfer, convey or otherwise
dispose of all or substantially all its assets in one or more related
transactions, to another corporation, Person or entity unless:

  (1) Lyondell is the surviving corporation or the entity or the Person
      formed by or surviving any consolidation or merger (if other than
      Lyondell) or to which the sale, assignment, transfer, conveyance or
      other disposition will have been made is a corporation organized or
      existing under the laws of the United States, any state thereof or the
      District of Columbia;

  (2) the corporation formed by or surviving any consolidation or merger (if
      other than Lyondell) or the corporation to which the sale, assignment,
      transfer, lease, conveyance or other disposition will have been made
      assumes all the obligations of Lyondell under the new notes issued
      under the applicable indenture and the applicable indenture under a
      supplemental indenture in form reasonably satisfactory to the Trustee
      under that indenture;

  (3) immediately after the transaction no Default or Event of Default
      exists; and

  (4) Lyondell or the entity or Person formed by or surviving any
      consolidation or merger (if other than Lyondell), or to which the sale,
      assignment, transfer, lease, conveyance or other disposition will have
      been made:

    (a) will have a Consolidated Net Worth immediately after the
        transaction equal to or greater than the Consolidated Net Worth of
        Lyondell immediately preceding the transaction; and

    (b) except with respect to a consolidation or merger of Lyondell with
        or into a Person that has no outstanding Indebtedness, will, at the
        time of the transaction and after giving pro forma effect thereto
        as if the transaction had occurred at the beginning of the
        applicable four-quarter period, be permitted to incur at least
        $1.00 of additional Indebtedness under the Fixed Charge Coverage
        Ratio test described in the first paragraph of the covenant in the
        applicable indenture described above under the caption "--
        Incurrence of Indebtedness and Issuance of Preferred Stock."

The foregoing restrictions will not prohibit the merger or consolidation of a
Wholly Owned Restricted Subsidiary with Lyondell; provided that, in connection
with the merger or consolidation, no consideration other than common stock in
the surviving Person or Lyondell will be issued or distributed to the
stockholders of Lyondell.


                                       96
<PAGE>

   The sale, assignment, transfer, lease, conveyance or other disposition by
Lyondell of all or substantially all its property or assets taken as a whole to
one or more of Lyondell's Subsidiaries will not relieve Lyondell from its
obligations under the indentures and the new notes. In addition, Lyondell may
not lease all or substantially all its assets to another Person.

 Transactions with Affiliates

   Lyondell will not, and will not permit any of its Restricted Subsidiaries
to, sell, lease, transfer or otherwise dispose of any of its properties or
assets to, or purchase any property or assets from, or enter into or make any
contract, agreement, understanding, loan, advance or Guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless:

  (1) the Affiliate Transaction is on an arms-length basis; and

  (2) Lyondell delivers to the Trustee:

    (a) with respect to any Affiliate Transaction involving aggregate
        consideration in excess of $10 million, a resolution of the board
        of directors described in an Officers' Certificate certifying that
        the Affiliate Transaction complies with clause (1) above and that
        the Affiliate Transaction has been approved by a majority of the
        disinterested members of the board of directors; and

    (b) with respect to any Affiliate Transaction involving aggregate
        consideration in excess of $25 million, an opinion as to the
        fairness to Lyondell or the Restricted Subsidiary of the Affiliate
        Transaction from a financial point of view issued by an investment
        banking firm of national standing;

provided that:

  (1) transactions or payments under any employment arrangements or employee,
      officer or director benefit plans or arrangements entered into by
      Lyondell or any of its Restricted Subsidiaries in the ordinary course
      of business;

  (2) transactions between or among Lyondell and/or its Restricted
      Subsidiaries;

  (3) any Restricted Payment permitted by the provisions of the applicable
      indenture described under the caption "--Restricted Payments," of the
      type described in clause (1) or (2) of the first paragraph under this
      caption;

  (4) customary loans, advances, fees and compensation paid to, and indemnity
      provided on behalf of, officers, directors, employees or consultants of
      Lyondell or any of its Restricted Subsidiaries;

  (5) transactions entered into on an arms-length basis in the ordinary
      course of business between Lyondell or any of its Restricted
      Subsidiaries and any Joint Venture;

  (6) sales, including a sale in exchange for a promissory note of or Equity
      Interest in an Accounts Receivable Subsidiary, of accounts receivable
      and the provision of billing, collection and other services in
      connection therewith, in each case, to an Accounts Receivable
      Subsidiary in connection with any Receivables Facility; and

  (7) transactions under any contract or agreement in effect on the date of
      the applicable indenture as the same may be amended, modified or
      replaced from time to time so long as any contract or agreement as so
      amended, modified or replaced is, taken as a whole, no less favorable
      to Lyondell and its Restricted Subsidiaries than the contract or
      agreement as in effect on the date of the applicable indenture (as
      conclusively evidenced by a resolution of the board of directors);


                                       97

in each case, will not be deemed to be Affiliate Transactions and therefore not
subject to the requirements of clauses (1) and (2) of the initial paragraph
above.

 Limitations on Issuances of Guarantees of Indebtedness by Subsidiaries

   Lyondell will not permit any Restricted Subsidiary that is not a Subsidiary
Guarantor, directly or indirectly, to Guarantee or secure the payment of any
other Indebtedness of Lyondell or any of its Restricted Subsidiaries, except
Indebtedness of the Restricted Subsidiary or a Restricted Subsidiary of the
Restricted Subsidiary, unless the Restricted Subsidiary:

  (1) simultaneously executes and delivers a supplemental indenture to the
      applicable indenture providing for the Guarantee of the payment of the
      notes issued under the applicable indenture by the Restricted
      Subsidiary; and

  (2) waives and agrees not in any manner whatsoever to claim or take the
      benefit or advantage of, either:

    (a) any right to receive payment by way of subrogation against Lyondell
        or against any direct or indirect security for the obligation, or
        any right to be reimbursed, indemnified or exonerated by or for the
        account of Lyondell in respect thereof; or

    (b) any right to receive payment, in the nature of contribution or for
        any other reason, from any other Subsidiary Guarantor with respect
        to the payment, in each case so long as any amount payable by
        Lyondell under the applicable indenture or under the new notes
        remains unpaid;

provided that this paragraph will not be applicable to (x) any Guarantee of any
Restricted Subsidiary that existed at the time the Person became a Restricted
Subsidiary and was not incurred in connection with, or in contemplation of, the
Person becoming a Restricted Subsidiary, (y) Guarantees of Indebtedness of a
Restricted Subsidiary that is a Foreign Subsidiary by a Restricted Subsidiary
that is a Foreign Subsidiary or (z) the granting of Liens by a Joint Venture
Subsidiary to secure Indebtedness under the Existing Credit Facility and the
Senior Secured Notes.

   In the case of the Senior Subordinated Notes, if the new notes are
subordinated by their terms to the Guaranteed Indebtedness, then the Subsidiary
Guarantee will be subordinated to the guarantee of the Guaranteed Indebtedness.
If the new notes are pari passu with the Guaranteed Indebtedness, then the
Subsidiary Guarantee will be pari passu with, or senior to, the guarantee of
the Guaranteed Indebtedness. If the new notes are senior to the Guaranteed
Indebtedness, then the Subsidiary Guarantee will be senior to the guarantee of
the Guaranteed Indebtedness at least to the extent that the new notes are
senior to the Guaranteed Indebtedness.

Notwithstanding the foregoing, each Subsidiary Guarantee by a Restricted
Subsidiary will provide by its terms that it will be automatically and
unconditionally released and discharged upon:

  (1) any sale, exchange or transfer, to any Person not an Affiliate of
      Lyondell, of all Lyondell's and each Restricted Subsidiary's Capital
      Stock in the Restricted Subsidiary, which sale, exchange or transfer is
      not prohibited by the indentures;

  (2) the release or discharge of the Guarantee which resulted in the
      creation of the Subsidiary Guarantee or, in the case of the Subsidiary
      Guarantee of Lyondell Nederland issued on May 17, 1999, the release or
      discharge of its Guarantee of Indebtedness under the Existing Credit
      Facility, except a discharge or release by or as a result of payment
      under the Guarantee; and

  (3) the designation of the Restricted Subsidiary as an Unrestricted
      Subsidiary in accordance with the terms of the indentures.


                                       98
<PAGE>

 Accounts Receivable Facilities

   Lyondell may, and any of its Restricted Subsidiaries may, sell at any time
and from time to time, accounts receivable to any Accounts Receivable
Subsidiary. However, the aggregate consideration received in each sale must be
at least equal to the aggregate fair market value of the receivables sold. The
term "sell" includes a sale in exchange for a promissory note of or Equity
Interest in the Accounts Receivable Subsidiary.

 No Amendment to Subordination Provisions

   Under the Senior Secured Note Indentures, Lyondell may not amend, modify or
alter the Senior Subordinated Note Indenture in any way that would:

  (1) increase the principal of, advance the final maturity date of or
      shorten the Weighted Average Life to Maturity of any Senior
      Subordinated Notes such that the final maturity date of the Senior
      Subordinated Notes is earlier than the 91st day following the final
      maturity date of the Senior Secured Notes; or

  (2) amend the subordination provisions of the Senior Subordinated Note
      Indenture or any of the defined terms used in the Senior Subordinated
      Note Indenture in a manner that would be adverse to the holders of the
      Senior Secured Notes.

 No Senior Subordinated Debt

   Under the Senior Subordinated Note Indenture, Lyondell and the Subsidiary
Guarantors each may not incur any Indebtedness that under its terms is
subordinate or junior in right of payment to any Senior Indebtedness and senior
in any respect in right of payment to the Senior Subordinated Notes or the
Senior Subordinated Note Guarantees. However, this limitation will not apply to
distinctions between categories of Senior Indebtedness of Lyondell or a
Subsidiary Guarantor that exist by reason of any Liens or Guarantees arising or
created in respect of some but not all the Senior Indebtedness.

Limitation of Applicability of Covenants if New Notes Rated Investment Grade

   Notwithstanding the covenants summarized above, Lyondell's and its
Restricted Subsidiaries' obligations to comply with the covenants described
under the captions "Restrictive Covenants--Restricted Payments," "--Incurrence
of Indebtedness and Issuance of Preferred Stock," "--Dividend and other Payment
Restrictions Affecting Subsidiaries," "--Line of Business," "--Limitation on
Issuance of Guarantees of Indebtedness by Subsidiaries," "--Transactions with
Affiliates," "--Accounts Receivable Facilities" and "Repurchase at the Option
of the Holders--Asset Sales" will terminate and cease to have any further
effect from and after the first date when the new notes issued under the
applicable indenture are rated Investment Grade.

Reports

   Whether or not required by the rules and regulations of the SEC, so long as
any new notes issued thereunder are outstanding, Lyondell will furnish to each
Trustee and the holders of the new notes:

  . all quarterly and annual financial information that would be required to
    be contained in a filing with the SEC on Forms 10-Q and 10-K if Lyondell
    were required to file those forms, including a "Management's Discussion
    and Analysis of Financial Condition and Results of Operations" and, with
    respect to the annual information only, a report thereon by Lyondell's
    certified independent accountants; and

  . all current reports that would be required to be filed with the SEC on
    Form 8-K if Lyondell were required to file those reports.

   In addition, whether or not required by the rules and regulations of the
SEC, Lyondell will file a copy of all information and reports with the SEC for
public availability and make this information available to

                                       99
<PAGE>

securities analysts and prospective investors upon request. In addition,
Lyondell has agreed that, for so long as any new notes remain outstanding, it
will furnish to the holders, securities analysts and prospective investors,
upon their request, the information required to be delivered under Rule
144A(d)(4) under the Securities Act.

Events of Default and Remedies

   Each of the following constitutes an Event of Default with respect to the
new notes:

  (1) default for 30 days in the payment when due of interest or liquidated
      damages, whether or not prohibited by the subordination provisions of
      the Senior Subordinated Note Indenture;

  (2) default in payment when due of the principal of or premium, if any, on
      the new notes, at maturity or otherwise, whether or not prohibited by
      the subordination provisions of the Senior Subordinated Note Indenture;

  (3) failure by Lyondell to comply with the provisions described under the
      captions "--Repurchase at the Option of Holders--Change of Control,"
      "--Asset Sales" or "--Restrictive Covenants--Merger, Consolidation or
      Sale of Assets";

  (4) failure by Lyondell for 60 days after notice by the Trustee or holders
      of at least 25% in principal amount of the new notes then outstanding
      and issued to comply with any of its other agreements in the applicable
      indenture or the new notes;

  (5) any default occurs under any mortgage, indenture or instrument under
      which there may be issued or by which there may be secured or evidenced
      any Indebtedness for money borrowed by Lyondell or any of its
      Significant Subsidiaries or any Indebtedness for money borrowed
      Guaranteed by Lyondell or any of its Significant Subsidiaries if
      Lyondell or a Significant Subsidiary does not perform its payment
      obligations under the Guarantee within any grace period provided for in
      the documentation governing the Guarantee and, whether the Indebtedness
      or Guarantee exists on the date of the applicable indenture or is
      thereafter created, which default:

    (a) constitutes a Payment Default; or

    (b) results in the acceleration of the Indebtedness before its Stated
        Maturity;

    and in each case, the principal amount of any Indebtedness, together
    with the principal amount of any other Indebtedness under which there
    has been a Payment Default or that has been so accelerated, aggregates
    $50 million or more;

  (6) failure by Lyondell or any of its Significant Subsidiaries to pay a
      final judgment or final judgments aggregating in excess of $50 million,
      which judgment or judgments are not paid, discharged or stayed for a
      period of 60 days;

  (7) specified events of bankruptcy or insolvency with respect to Lyondell
      or any of its Significant Subsidiaries;

  (8) except as permitted by the applicable indenture:

    (a) any Subsidiary Guarantee will be held in any judicial proceeding to
        be unenforceable or invalid or will cease for any reason to be in
        full force and effect or any Subsidiary Guarantor; or

    (b) any Person acting on behalf of any Subsidiary Guarantor, will deny
        or disaffirm its obligations under the Subsidiary Guarantees; and

  (9) in the case of the Senior Secured Notes:

    (a) any of the Security Documents ceases to be in full force and
        effect;

    (b) any of the Security Documents ceases to give the holders of the
        Senior Secured Notes any of the Liens purported to be created
        thereby;

                                      100
<PAGE>

    (c) any of the Security Documents is declared null and void; or

    (d) Lyondell or any Restricted Subsidiary denies in writing that it has
        any further liability under any Security Document or gives written
        notice to that effect;

    However, it will not be an Event of Default if the event described in
    clause (9) above occurs in accordance with the terms of the applicable
    indenture or the terms of the Existing Credit Facility or the Security
    Documents, including the cessation of effectiveness of any Security
    Document in connection with the release of all collateral covered
    thereby according to the terms of the applicable indenture, the
    Existing Credit Facility and the Security Document, or if an event
    occurs that is waived by the requisite lenders under the Existing
    Credit Facility and, after that waiver, Lyondell is in compliance with
    the covenant described under "--Security." However, if a failure of the
    sort described in this clause (9) is susceptible of cure, no Event of
    Default will arise under this clause (9) with respect thereto until 30
    days after notice of the failure will have been given to Lyondell by
    the applicable Senior Secured Note Trustee or holders of at least 25%
    in principal amount of the then outstanding notes issued under the
    applicable indenture.

   If an Event of Default other than an Event of Default specified in clause
(7) above that occurs with respect to Lyondell or any Subsidiary Guarantor
occurs and is continuing under any indenture, the Trustee or the holders of at
least 25% in aggregate principal amount of the Series A Senior Secured Notes,
or Senior Subordinated Notes, as the case may be, then outstanding, by written
notice to Lyondell and to the applicable Trustee if the notice is given by the
holders (the "Acceleration Notice"), may, and the applicable Trustee at the
request of the holders will, declare the principal of and premium, if any, and
accrued interest and liquidated damages, if any, on the new notes to be
immediately due and payable. Upon a declaration of acceleration, the principal,
premium, if any, and accrued interest and liquidated damages, if any, will be
immediately due and payable. If an Event of Default specified in clause (7)
above occurs with respect to Lyondell or any Subsidiary Guarantor, the
principal of and premium, if any, and accrued interest and liquidated damages,
if any, on the new notes then outstanding will ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any holder.

   The holders of at least a majority in principal amount of the then
outstanding Series A Senior Secured Notes, Series B Senior Secured Notes or
Senior Subordinated Notes, as the case may be, by written notice to Lyondell
and to the applicable Trustee, may waive all past defaults and rescind and
annul a declaration of acceleration and its consequences under the Series A
Senior Secured Notes, Series B Senior Secured Notes or Senior Subordinated
Notes, as the case may be, if:

  (1) all existing Events of Default, other than the nonpayment of the
      principal of and premium, if any, and interest and liquidated damages,
      if any, on the new notes that have become due solely by the declaration
      of acceleration, have been cured or waived; and

  (2) the rescission would not conflict with any judgment or decree of a
      court of competent jurisdiction.

   For information as to the waiver of defaults, see "--Modification and
Waiver."

   The holders of at least a majority in aggregate principal amount of the then
outstanding Series A Senior Secured Notes, Series B Senior Secured Notes or
Senior Subordinated Notes, as the case may be, may direct the time, method and
place of conducting any proceeding for any remedy available to the applicable
Trustee or exercising any trust or power conferred on the applicable Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law
or the applicable indenture, that may involve the Trustee in personal
liability, or that the Trustee determines in good faith may be unduly
prejudicial to the rights of holders of the Series A Senior Secured Notes,
Series B Senior Secured Notes or Senior Subordinated Notes, as the case may be,
not joining in the giving of the direction and may take any other action it
deems proper that is not inconsistent with any direction received from holders
of the Series A Senior Secured Notes, Series B Senior Secured Notes or Senior
Subordinated Notes, as the case may be.


                                      101
<PAGE>

   A holder may not pursue any remedy with respect to the applicable indenture
or the Series A Senior Secured Notes, Series B Senior Secured Notes or Senior
Subordinated Notes, as the case may be, unless:

  (1) the holder gives the Trustee written notice of a continuing Event of
      Default;

  (2) the holders of at least 25% in aggregate principal amount of
      outstanding Series A Senior Secured Notes, Series B Senior Secured
      Notes or Senior Subordinated Notes, as the case may be, make a written
      request to the Trustee to pursue the remedy;

  (3) the holder or holders offer the applicable Trustee indemnity
      satisfactory to the Trustee against any costs, liability or expense;

  (4) the Trustee does not comply with the request within 60 days after
      receipt of the request and the offer of indemnity; and

  (5) during the 60-day period, the holders of at least a majority in
      aggregate principal amount of the outstanding Series A Senior Secured
      Notes, Series B Senior Secured Notes or Senior Subordinated Notes, as
      the case may be, do not give the Trustee a direction that is
      inconsistent with the request.

However, these limitations do not apply to the right of any holder of a Series
A Senior Secured Note, Series B Senior Secured Note or Senior Subordinated
Note, as the case may be, to receive payment of the principal of or premium, if
any, interest or liquidated damages, if any, on the new notes or to bring suit
for the enforcement of the payment, on or after the due date expressed in the
new notes, which right will not be impaired or affected without the consent of
the holder.

   Specified officers of Lyondell must certify, on or before a date not more
than 120 days after the end of each fiscal year, that they have conducted or
supervised a review of the activities of Lyondell and its Restricted
Subsidiaries and Lyondell's and its Restricted Subsidiaries' performance under
the applicable indenture and that, to the best of the officer's knowledge,
based upon this review, Lyondell has fulfilled all obligations under the
indenture. If there has been a default in the fulfillment of any obligation
under the applicable indenture, the certifying officers must specify each
default and the nature and status of any default. Lyondell will also be
obligated to notify the applicable Trustee promptly of any default or defaults
in the performance of any covenants or agreements under any indenture.

Modification and Waiver

   Modifications and amendments of the indentures may be made by Lyondell, the
Subsidiary Guarantors and the Trustee with the consent of the holders of not
less than a majority in aggregate principal amount of the then outstanding
Series A Senior Secured Notes, Series B Senior Secured Notes or Senior
Subordinated Notes, as the case may be. However, without the consent of each
holder affected thereby, no modification or amendment may:

  (1) change the Stated Maturity of the principal of, or any installment of
      interest on, any new note;

  (2) reduce the principal amount of or premium, if any, or interest or
      liquidated damages, if any, on any new note;

  (3) reduce any amount payable on redemption of the new notes or upon the
      occurrence of an Event of Default or reduce the Change of Control
      Payment or the amount to be paid in connection with an Asset Sale
      Offer;

  (4) change the place or currency of payment of principal of or premium, if
      any, or interest or liquidated damages, if any, on any new note;

  (5) impair the right to institute suit for the enforcement of any payment
      on or after the Stated Maturity or, in the case of a redemption, on or
      after the Redemption Date, of any new note;


                                      102
<PAGE>

  (6) reduce the above-stated percentage of the then outstanding notes the
      consent of whose holders is necessary to modify or amend an indenture;

  (7) waive a default in the payment of principal of or premium, if any, or
      interest or liquidated damages, if any, on the new notes, except as
      stated in the penultimate sentence of the second paragraph under the
      caption "--Events of Default and Remedies";

  (8) reduce the percentage or aggregate principal amount of the then
      outstanding notes the consent of whose holders is necessary for waiver
      of compliance with provisions of an indenture or for waiver of
      defaults;

  (9) modify or change any provision of an indenture affecting the ranking of
      the new notes or the Subsidiary Guarantees in a manner adverse to the
      holders of the new notes;

  (10) release any Subsidiary Guarantor from any of its obligations under its
       Subsidiary Guarantee or an indenture other than in accordance with the
       provisions of the indenture, or amend or modify any provision relating
       to the release; or

  (11) in the case of the Senior Secured Notes Indentures, directly or
       indirectly release the Liens created by the Security Documents on all
       or substantially all the Collateral, other than in accordance with the
       terms of the Existing Credit Facility or the Security Documents or
       with the consent of the requisite lenders under the Existing Credit
       Facility if, after the consent, Lyondell is in compliance with the
       covenant described under "--Security".

   Neither Lyondell nor any of its Subsidiaries or Affiliates will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any new notes for or as an
inducement to any consent, waiver or amendment of any of the terms or
provisions of any indenture or the new notes issued thereunder unless the
consideration is offered to be paid or agreed to be paid to all holders of the
new notes that consent, waive or agree to amend the term or provision in the
time frame stated in the solicitation documents relating to the consent, waiver
or agreement.

Defeasance

   Defeasance and Discharge. Lyondell will be deemed to have paid and will be
discharged from any and all obligations in respect of the new notes issued
under any indenture, and any Subsidiary Guarantor will be discharged from any
and all obligations in respect of its Subsidiary Guarantee on the 123rd day
after the deposit referred to below. Thereafter the provisions of the
applicable indenture will no longer be in effect with respect to the new notes
and the Subsidiary Guarantees except for, among other matters, obligations to
register the transfer or exchange of the new notes, to replace stolen, lost or
mutilated notes, to maintain paying agencies and to hold monies for payment in
trust, if, among other things:

  (1) Lyondell has deposited with the Trustee, in trust, money and/or U.S.
      Government obligations that through the payment of interest and
      principal in respect of which obligations in accordance with their
      terms will provide money in an amount sufficient to pay the principal
      of and premium, if any, and accrued interest and liquidated damages, if
      any, on the new notes on the Stated Maturity of the payments in
      accordance with the terms of the applicable indenture and the new notes
      to redemption or maturity, as the case may be;

  (2) Lyondell has delivered to the Trustee:

    (a) either (x) 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 Lyondell's exercise of its option under this
        "Defeasance" provision and will be subject to federal income tax on
        the same amount and in the same manner and at the same times as
        would have been the case if the deposit, defeasance and discharge
        had not occurred, which opinion of counsel must be based upon and
        accompanied by a copy of a ruling of the Internal Revenue Service
        to the same effect unless there has been a

                                      103
<PAGE>

       change in applicable federal income tax law after May 17, 1999 such
       that a ruling is no longer required or (y) a ruling directed to the
       Trustee or Lyondell received from the Internal Revenue Service to the
       same effect as the aforementioned opinion of counsel; and

    (b) an opinion of counsel to the effect that the creation of the
        defeasance trust does not violate the Investment Company Act of 1940
        and after the passage of 123 days following the deposit, the trust
        fund will not be subject to the effect of Section 547 of the United
        States Bankruptcy Code or Section 15 of the New York Debtor and
        Creditor Law, or any comparable provision or applicable law;

  (3) immediately after giving effect to the deposit on a pro forma basis, no
      Event of Default, or event that after the giving of notice or lapse of
      time or both would become an Event of Default, will have occurred and
      be continuing on the date of the deposit or during the period ending on
      the 123rd day after the date of the deposit, and the deposit will not
      result in a breach or violation of, or constitute a default under, any
      other agreement or instrument to which Lyondell is a party or by which
      Lyondell is bound; and

  (4) if at such time the new notes are listed on a national securities
      exchange, Lyondell has delivered to the Trustee an opinion of counsel
      to the effect that the new notes will not be delisted as a result of
      the deposit, defeasance and discharge.

   Defeasance of Covenants and Events of Default. The provisions of an
indenture will no longer be in effect with respect to the provision described
under "--Security," clause (4) under "--Merger, Consolidation and Sale of
Assets" and all the covenants described under "--Restrictive Covenants," and
clauses (3) and (4) under "--Events of Default" with respect to the covenants
and clause (4) under "--Merger, Consolidation and Sale of Assets," and clauses
(5), (6) and (9) under "--Events of Default" will be deemed not to be Events
of Default, upon, among other things, the deposit with the applicable Trustee,
in trust, of money and/or U.S. Government obligations that through the payment
of interest and principal in respect of which obligations in accordance with
their terms will provide money in an amount sufficient to pay the principal of
and premium, if any, and accrued interest and liquidated damages, if any, on
the new notes on the Stated Maturity of the payments in accordance with the
terms of the applicable indenture and the new notes, the satisfaction of the
provisions described in clauses (2)(b), (3) and (4) of the preceding paragraph
and the delivery by Lyondell to the Trustee of an opinion of counsel to the
effect that, among other things, the holders will not recognize income, gain
or loss for federal income tax purposes as a result of the deposit and
defeasance of some covenants and Events of Default and will be subject to
federal income tax on the same amount and in the same manner and at the same
times as would have been the case if the deposit and defeasance had not
occurred.

   Defeasance and Other Events of Default. In the event Lyondell exercises its
option to omit compliance with some covenants and provisions of any indenture
with respect to the new notes issued thereunder as described in the
immediately preceding paragraph and the new notes are declared due and payable
because of the occurrence of an Event of Default that remains applicable, the
amount of money and/or U.S. Government obligations on deposit with the
applicable Trustee will be sufficient to pay amounts due on the new notes at
the time of their Stated Maturity but may not be sufficient to pay amounts due
on the new notes at the time of the acceleration resulting from the Event of
Default. However, Lyondell will remain liable for these payments.

No Personal Liability of Directors, Officers, Employees and Stockholders

   No director, officer, employee, incorporator, stockholder or other holder
of Equity Interests of Lyondell or the Subsidiary Guarantors, as such, will
have any liability for any obligations of Lyondell or the Subsidiary
Guarantors under the new notes, the Subsidiary Guarantees, the indentures or
for any claim based on, in respect of, or by reason of, the obligations or
their creation. Each holder of new notes by accepting a new note waives and
releases all liability with respect to these persons. The waiver and release
are part of the consideration for the issuance of the new notes. The waiver
may not be effective to waive liabilities under the federal securities laws
and it is the view of the SEC that this waiver is against public policy.

                                      104
<PAGE>

Transfer and Exchange

   A holder may transfer or exchange new notes in accordance with the
indentures. The Registrar and the Trustees may require a holder, among other
things, to furnish appropriate endorsements and transfer documents and Lyondell
may require a holder to pay any taxes and fees required by law or permitted by
the indentures.

   The registered holder of a new note will be treated as the owner of the new
note for all purposes.

Concerning the Trustee

   Each indenture contains limitations on the rights of the applicable Trustee,
should it become a creditor of Lyondell, to obtain payment of claims in some
cases, or to realize on some property received in respect of any claim as
security or otherwise. Each Trustee will be permitted to engage in other
transactions. However, if a Trustee acquires any conflicting interest it must
eliminate the conflict within 90 days, apply to the SEC for permission to
continue or resign.

   The holders of a majority in principal amount of the then outstanding notes
issued under an indenture will have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
applicable Trustee, subject to some exceptions. In case an Event of Default
occurs (which will not be cured), the Trustee will be required, in the exercise
of its power, to use the degree of care of a prudent man in the conduct of his
own affairs. Subject to these provisions, the Trustees will not be under any
obligation to exercise any rights or powers under the indentures at the request

Subsidiary of Lyondell, Lyondell will be deemed to have made an Investment on

      a sale of a partial interest in an asset, as might be achieved, for

      Affiliate of the Acquiring Person contemplated by the terms of the

  (b) either (i) the Subsidiary to be so designated has total assets of
      $1,000 or less or (ii) if the Subsidiary has assets greater than
      $1,000, the designation would be permitted under the covenant described
      above under the caption "--Restrictive Covenants--Restricted Payments";

  (c) if applicable, the Investment and the incurrence of Indebtedness
      referred to in clause (a) of this proviso would be permitted under the
      covenants described above under the captions "--Restricted Payments"
      and "--Incurrence of Indebtedness and Issuance of Preferred Stock"; and

  (d) in the case of any Subsidiary that is a Joint Venture as of the date of
      its designation as an Unrestricted Subsidiary, the Subsidiary has an
      aggregate of 15% or more of its outstanding Capital Stock or other
      voting interests other than directors' qualifying shares held by
      another Person other than Lyondell or any Restricted Subsidiary or any
      Affiliate of Lyondell.

   Any designation by the board of directors of Lyondell under clause (1) above
will be evidenced to the Trustee by filing with the Trustee a certified copy of
the Board Resolution giving effect to the designation and an Officers'
Certificate certifying that the designation complied with the foregoing
conditions and was permitted by the covenants described above under the
captions "--Restrictive Covenants--Restricted Payments" and "--Incurrence of
Indebtedness and Issuance of Preferred Stock."

   If:

  (1) at any time, any Unrestricted Subsidiary would fail to meet the
      foregoing requirements of clause (d) because Lyondell has acquired more
      than 85% of the outstanding Capital Stock or other voting interests of
      any Subsidiary that was a Joint Venture on the date of its designation
      as an Unrestricted Subsidiary; or

  (2) at any time Lyondell or any Restricted Subsidiary Guarantees any
      Indebtedness of the Unrestricted Subsidiary or makes any other
      Investment in the Unrestricted Subsidiary and the incurrence of
      Indebtedness or Investment would not be permitted under the covenants
      described above under the caption "--Restrictive Covenants--Incurrence
      of Indebtedness and Issuance of Preferred Stock" or "--Restrictive
      Covenants--Restricted Payments";

it will thereafter cease to be an Unrestricted Subsidiary for purposes of the
applicable indenture and any Indebtedness of the Subsidiary will be deemed to
be incurred by a Restricted Subsidiary of Lyondell as of the date and, if the
Indebtedness is not permitted to be incurred as of the date under the covenant
described above under the caption "--Restrictive Covenants--Incurrence of
Indebtedness and Issuance of Preferred Stock," Lyondell will be in default of
the covenant. The board of directors of Lyondell may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary; provided that the
designation will be deemed to be an incurrence of Indebtedness by a Restricted
Subsidiary of Lyondell of any outstanding Indebtedness of the Unrestricted
Subsidiary and the designation will only be permitted if:

  (1) the Indebtedness is permitted under the covenant described above under
      the caption "--Incurrence of Indebtedness and Issuance of Preferred
      Stock"; and

  (2) no Default or Event of Default would be in existence following the
      designation.

   "Weighted Average Life to Maturity" means, when applied to any Indebtedness
at any date, the number of years obtained by dividing:

  (1) the sum of the products obtained by multiplying:

    (a) the amount of each then remaining installment, sinking fund, serial
        maturity or other required payments of principal, including payment
        at final maturity, in respect thereof; by

    (b) the number of years calculated to the nearest one-twelfth that will
        elapse between the date and the making of the payment;

     by:

  (2) the then outstanding principal amount of the Indebtedness.

                United States Federal Income Tax Considerations

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

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

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

                         Registration Rights Agreement

   The description of the registration rights agreement set forth below is a
summary of the material provisions of the registration rights agreement. The
registration rights agreement is filed as an exhibit to the registration
statement of which this prospectus is a part.

Exchange Offer Registration Statement

   In connection with the issuance of the outstanding notes, we entered into a
registration rights agreement with the initial purchasers of the outstanding
notes. Under the registration rights agreement, we agreed to:

  . file a registration statement with the SEC on or before 90 days after
    issuance of the outstanding notes;

  . use our best efforts to cause the registration statement to be declared
    effective at the earliest possible date but no later than 210 days after
    the date of issuance of the outstanding notes;

  . use our best efforts to consummate the exchange offers no later than 30
    business days after the registration statement is declared effective;

  . keep the exchange offers open for acceptance of tenders for a period of
    not less than 20 business days after the date notice of the exchange
    offers is mailed to holders of the outstanding notes; and

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

   To participate in an exchange offer, each holder must represent that it:

  . is not one of our affiliates;

  . is not a broker-dealer tendering outstanding notes acquired directly from
    us for its own account;


                                      121
<PAGE>

  . has no arrangement or understanding with any person to participate in a
    distribution of the new notes; and

  . is acquiring the new notes in the ordinary course of business.

   If the holder is a broker-dealer that will receive new notes for its own
account in exchange for outstanding notes that were acquired by it as a result
of market-making activities or other trading activities, it will be required to
acknowledge that it will deliver a prospectus in connection with the resale of
any new notes so acquired.

   As soon as practicable after the exchange offer registration statement
becomes effective, but not more than 30 business days later, we will offer the
holders of outstanding notes who are not prohibited by any law or policy of the
SEC from participating in these exchange offers the opportunity to exchange
their outstanding notes for new notes registered under the Securities Act that
are substantially identical to the outstanding notes, except that the new notes
will not contain terms with respect to transfer restrictions, registration
rights and liquidated damages.

   The registration rights agreement also provides that we will:

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

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

Shelf Registration Statement

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

  . if the exchange offers as contemplated by the registration rights
    agreement are not permitted by applicable law; or

  . any holder of outstanding notes notifies us before the 20th business day
    following the consummation of the applicable exchange offer that it:

    (1) is prohibited by law or SEC policy from participating in the
        exchange offers;

    (2) may not resell the new notes to the public without delivering a
        prospectus, and the prospectus contained in the exchange offer
        registration statement is not appropriate or available for resales
        by the holder; or

    (3) is a broker-dealer and holds outstanding notes acquired directly
        from Lyondell or any of Lyondell's affiliates.

   A holder who sells outstanding notes under the shelf registration statement
generally will be:

  . required to be named as a selling security holder in the related
    prospectus and to deliver a prospectus to purchasers;

  . subject to some of the civil liability provisions under the Securities
    Act in connection with resales of the outstanding notes; and

  . bound by the applicable provisions of the registration rights agreement,
    including some of the indemnification obligations.

                                      122
<PAGE>

   If filed, we will use our reasonable best efforts to keep the shelf
registration statement effective for a period of two years after May 17, 1999.

Liquidated Damages

   If a registration default under the registration rights agreement occurs, we
will be obligated to pay liquidated damages to each holder of outstanding notes
at an amount equal to $0.05 per week per $1000 in principal amount of
outstanding notes affected. If a registration default is not cured within 90
days, the amount of liquidated damages will increase by an additional $0.05 per
week per $1000 in principal amount of outstanding notes affected with respect
to each subsequent 90-day period during which a registration default continues,
up to a maximum amount of liquidated damages of $0.50 per week per $1000 of
principal amount of outstanding notes.

   A registration default occurs if:

  . a registration statement is not timely filed with the SEC;

  . a registration statement is not declared effective on or before the
    applicable deadline;

  . one or more of the exchange offers are not consummated within 30 business
    days after the exchange offer registration statement is declared
    effective; or

  . a registration statement is filed and declared effective but ceases to be
    effective or usable.

Following the cure of all registration defaults, the accrual of liquidated
damages will cease. We are not required to pay liquidated damages for more than
one registration default at a given time. We are not required to pay liquidated
damages to a holder who has not furnished to Lyondell the information specified
in the registration rights agreement.

   We will pay all accrued but unpaid liquidated damages to the entitled
holders in the manner provided for payment of interest under the applicable
indenture.

                         Book-entry; Delivery and Form

Description of DTC

   The description of the operations and procedures of DTC, Euroclear and Cedel
set forth below is provided solely as a matter of convenience. These operations
and procedures are solely within the control of the respective settlement
systems and are subject to change by them from time to time. We do not take any
responsibility for these operations or procedures, and investors are urged to
contact the relevant system or its participants directly to discuss these
matters.

   DTC has advised us that it is a:

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

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

  . member of the Federal Reserve System;

  . ""clearing corporation" within the meaning of the Uniform Commercial
    Code; and

  . ""clearing agency" registered under Section 17A of the Securities
    Exchange Act of 1934.

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

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

The Global Notes

   We expect that under procedures established by DTC:

  . upon deposit of the global notes with DTC or its custodian, DTC will
    credit on its internal system the portion of the global notes
    corresponding to the respective amounts of the global notes registered to
    the respective accounts of persons who have accounts with the depository;

  . ownership of the new notes will be shown on records maintained by DTC or
    its nominee; and

  . transfers of ownership of the new notes will be effected only through
    records maintained by DTC or its nominee.

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

  . be entitled to have new notes represented by global notes registered in
    their names;

                                      124
<PAGE>

  . receive or be entitled to receive physical delivery of certificated new
    notes; and

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

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

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

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

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

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

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

                                      125
<PAGE>

Certificated Notes

   Interests in the global notes may be exchanged for certificated securities
if:

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

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

  . other events occur as provided in the applicable indenture.

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

   Neither Lyondell, Lyondell Worldwide, Lyondell Nederland, nor the trustee
will be liable for any delay by DTC or any participant or indirect participant
in identifying the beneficial owners of the related notes. Each person is
protected in conclusively relying on instructions from DTC for all purposes,
including with respect to the registration and delivery of the new notes, and
the respective principal amounts of the new notes.

                                      126

                              Plan of Distribution

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

  . you acquire the new notes in the ordinary course of your business; and

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

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

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

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

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

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

   The staff of the SEC has taken the position that participating broker-
dealers may fulfill their prospectus delivery requirements with respect to
transactions involving an exchange of securities such as these exchange offers,
other than a resale of an unsold allotment from the original sale of the
outstanding notes, by delivering the prospectus contained in the exchange offer
registration statement. Broker-dealers who acquired the outstanding notes from
Lyondell may not rely on SEC staff interpretations. They must comply with the
registration and prospectus delivery requirements of the Securities Act,
including being named as selling noteholders, in order to resell the
outstanding notes or the new notes. In the registration rights agreement, we
agreed to permit participating broker-dealers to use this prospectus in
connection with the resale of the new notes. We have agreed that we will make
this prospectus, and any amendment or supplement to this prospectus, available
for a period up to 180 days after the expiration of each exchange offer to any
broker-dealer that requests these documents in the applicable letter of
transmittal. In addition, until     , 1999, all dealers effecting transactions
in the new notes may be required to deliver this prospectus.

   If you wish to exchange your outstanding notes for new notes in an exchange
offer, you will be required to make representations to us as described in "The
Exchange Offers--Purpose and Effect of the Exchange Offer" and "--Procedures
for Tendering--Your Representations to Us" of this prospectus and in the
applicable letter of transmittal. In addition, if you are a broker-dealer who
receives the new notes for your own account in exchange for outstanding notes
that were acquired by you as a result of market-making activities or other
trading activities, you will be required to acknowledge that you will deliver a
prospectus in connection with any resale by you of the new notes.

   We will not receive any proceeds from any sale of the new notes by broker-
dealers. Broker-dealers who receive the new notes for their own account in the
exchange offers may sell them from time to time in one or more transactions
either:

  . in the over-the-counter market;

  . in negotiated transactions;

                                      127
<PAGE>

  . through the writing of options on the new notes or a combination of
    methods of resale;

  . at market prices prevailing at the time of resale; or

  . at prices related to prevailing market prices or negotiated prices.

   Any resale of the new notes may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of
commissions or concessions from any broker-dealer or the purchasers of any new
notes. Any broker-dealer that resells the new notes it received for its own
account in an exchange offer and any broker or dealer that participates in a
distribution of the new notes may be deemed to be an "underwriter" within the
meaning of the Securities Act. Any profit on any resale of the new notes and
any commissions or concessions received by any persons may be deemed to be
underwriting compensation under the Securities Act. Each broker-dealer that
receives the new notes for its own account using a registered exchange offer
must acknowledge that it will deliver a prospectus in connection with any
resale of the new notes. Each letter of transmittal states that by
acknowledging and delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

   We have agreed to pay all expenses incidental to each exchange offer other
than commissions and concessions of any brokers or dealers. We will indemnify
holders of the outstanding notes, including any broker-dealers, against some
liabilities, including liabilities under the Securities Act, as provided in the
registration rights agreement.

ITEM 20. Indemnification of Directors and Officers

 By-Law Provisions

Lyondell

   Lyondell's By-Laws provide that Lyondell will indemnify each of its officers
and directors to the fullest extent authorized by Section 145 of the General
Corporation Law of the State of Delaware. Article V of the By-Laws reads as
follows:

     (a) Indemnification of Officers and Directors. Lyondell will indemnify
  the officers and directors of Lyondell with respect to all matters to which
  Section 145 of the General Corporation Law of the State of Delaware may in
  any way relate, to the fullest extent permitted or allowed by the laws of
  the State of Delaware, whether or not specifically required, permitted or
  allowed by said Section 145. Any repeal or modification of this Section
  will not in any way diminish any rights to indemnification of such person
  or the obligations of Lyondell that may have previously arisen hereunder.

     (b) Non-Exclusivity of Rights. The right to indemnification and the
  payment of expenses incurred in defending a proceeding in advance of its
  final disposition conferred in this Section will not be exclusive of any
  other right which any person may have or hereafter acquire under any
  statute, Lyondell's Certificate of Incorporation, any By-Law, any
  agreement, a vote of Company stockholders or of disinterested Company
  directors or otherwise, both as to action in that person's official
  capacity and as to action in any other capacity by holding such office, and
  will continue after the person ceases to serve Lyondell as a director or
  officer or to serve another entity at the request of Lyondell.

     (c) Insurance. Lyondell may maintain insurance, at its expense, to
  protect itself and any director or officer of Lyondell or another
  corporation, partnership, joint venture, trust or other enterprise against
  any expense, liability or loss, whether or not Lyondell would have the
  power to indemnify such person against such expense, liability or loss
  under the General Corporation Law of Delaware.

     (d) Indemnity Agreements. Lyondell may from time to time enter into
  indemnity agreements with the persons who are members of its board of
  directors, its elected officers and with such other persons as the board of
  directors may designate, the form of such indemnity agreements to be
  approved by a majority of the Board then in office.

     (e) Indemnification of Employees and Agents of Lyondell. Lyondell may,
  under procedures authorized from time to time by the board of directors,
  grant rights to indemnification, and to payment by Lyondell of the expenses
  incurred in defending any proceeding in advance of its final disposition to
  any employee or agent of Lyondell to the fullest extent of the provisions
  of this Article V.

 Delaware General Corporation Law Provisions

   Section 145 of the General Corporation Law of the State of Delaware
provides:

     (a) A corporation will have power to indemnify any person who was or is
  a party or is threatened to be made a party to any threatened, pending or
  completed action, suit or proceeding, whether civil, criminal,
  administrative or investigative (other than an action by or in the right of
  the corporation) by reason of the fact that the 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, partnership, joint venture, trust or other
  enterprise, against expenses (including attorneys' fees), judgments, fines
  and amounts paid in settlement actually and reasonably incurred by the
  person in connection with such action, suit or proceeding if the person
  acted in good faith and in a manner the person reasonably believed to be in
  or not opposed to the best interests of the corporation, and, with

                                      II-1
<PAGE>

  respect to any criminal action or proceeding, had no reasonable cause to
  believe the person's conduct was unlawful. The termination of any action,
  suit or proceeding by judgment, order, settlement, conviction, or upon a
  plea of nolo contendere or its equivalent, will not, of itself, create a
  presumption that the person did not act in good faith and in a manner which
  the person reasonably believed to be in or not opposed to the best
  interests of the corporation, and, with respect to any criminal action or
  proceeding, had reasonable cause to believe that the person's conduct was
  unlawful.

     (b) A corporation will have power to indemnify any person who was or is
  a party or is threatened to be made a party to any threatened, pending or
  completed action or suit by or in the right of the corporation to procure a
  judgment in its favor by reason of the fact that the 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, partnership, joint venture, trust or other
  enterprise against expenses (including attorneys' fees) actually and
  reasonably incurred by the person in connection with the defense or
  settlement of such action or suit if the person acted in good faith and in
  a manner the person reasonably believed to be in or not opposed to the best
  interests of the corporation and except that no indemnification will be
  made in respect of any claim, issue or matter as to which such person will
  have been adjudged to be liable to the corporation unless and only to the
  extent that the Court of Chancery or the court in which such action or suit
  was brought will determine upon application that, despite the adjudication
  of liability but in view of all the circumstances of the case, such person
  is fairly and reasonably entitled to indemnity for such expenses which the
  Court of Chancery or such other court will deem proper.

     (c) To the extent that a present or former director or officer of a
  corporation has been successful on the merits or otherwise in defense of
  any action, suit or proceeding referred to in subsections (a) and (b) of
  this section or in defense of any claim, issue or matter therein, such
  person will be indemnified against expenses (including attorneys' fees)
  actually and reasonably incurred by such person in connection therewith.

     (d) Any indemnification under subsections (a) and (b) of this section
  (unless ordered by a court) will be made by the corporation only as
  authorized in the specific case upon a determination that indemnification
  of the present or former director, officer, employee or agent is proper in
  the circumstances because the person has met the applicable standard of
  conduct set forth in subsections (a) and (b) of this section. Such
  determination will be made, with respect to a person who is a director or
  officer at the time of such determination, (1) by a majority vote of the
  directors who are not parties to such action, suit or proceeding, even
  though less than a quorum, or (2) by a committee of such directors
  designated by majority vote of such directors, even though less than a
  quorum, or (3) if there are no such directors, or if such directors so
  direct, by independent legal counsel in a written opinion, or (4) by the
  stockholders.

     (e) Expenses (including attorneys' fees) incurred by an officer or
  director in defending any civil, criminal, administrative, or investigative
  action, suit or proceeding may be paid by the corporation in advance of the
  final disposition of such action, suit or proceeding upon receipt of an
  undertaking by or on behalf of such director or officer to repay such
  amount if it will ultimately be determined that such person is not entitled
  to be indemnified by the corporation as authorized in this section. Such
  expenses (including attorneys' fees) incurred by former directors and
  officers and other employees and agents may be so paid upon such terms and
  conditions, if any, as the corporation deems appropriate.

     (f) The indemnification and advancement of expenses provided by, or
  granted pursuant to, the other subsections of this section will not be
  deemed exclusive of any other rights to which those seeking indemnification
  or advancement of expenses may be entitled under any bylaw, agreement, vote
  of stockholders or disinterested directors or otherwise, both as to action
  in such person's official capacity and as to action in another capacity
  while holding such office.

     (g) A corporation will have power to purchase and maintain insurance on
  behalf of any person who 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,
  partnership, joint venture, trust

                                      II-2
<PAGE>

  or other enterprise against any liability asserted against such person and
  incurred by such person in any such capacity, or arising out of such
  person's status as such, whether or not the corporation would have the
  power to indemnify such person against such liability under this section.

     (h) For purposes of this section, references to "the corporation" will
  include, in addition to the resulting corporation, any constituent
  corporation (including any constituent of a constituent) absorbed in a
  consolidation or merger which, if its separate existence had continued,
  would have had power and authority to indemnify its directors, officers,
  and employees or agents, so that any person who is or was a director,
  officer, employee or agent of such constituent corporation, or is or was
  serving at the request of such constituent corporation as director,
  officer, employee or agent of another corporation, partnership, joint
  venture, trust or other enterprise, will stand in the same position under
  this section with respect to the resulting or surviving corporation as such
  person would have with respect to such constituent corporation if its
  separate existence had continued.

     (i) For purposes of this section, references to "other enterprises" will
  include employee benefit plans; references to "fines" will include any
  excise taxes assessed on a person with respect to an employee benefit plan;
  and references to "serving at the request of the corporation" will include
  any service as a director, officer, employee or agent of the corporation
  which imposes duties on, or involves services by, such director, officer,
  employee or agent with respect to an employee benefit plan, its
  participants or beneficiaries; and a person who acted in good faith and in
  a manner such person reasonably believed to be in the interest of the
  participants and beneficiaries of an employee benefit plan will be deemed
  to have acted in a manner "not opposed to the best interests of the
  corporation" as referred to in this section.

     (j) The indemnification and advancement of expenses provided by, or
  granted pursuant to, this section will, unless otherwise provided when
  authorized or ratified, continue as to a person who has ceased to be a
  director, officer, employee or agent and will inure to the benefit of the
  heirs, executors and administrators of such a person.

     (k) The Court of Chancery is hereby vested with exclusive jurisdiction
  to hear and determine all actions for advancement of expenses or
  indemnification brought under this section or under any bylaw, agreement,
  vote of stockholders or disinterested directors, or otherwise. The Court of
  Chancery may summarily determine a corporation's obligation to advance
  expenses (including attorneys' fees).

 Certificate of Incorporation Provisions

Lyondell

   Lyondell's Certificate of Incorporation limits the personal liability of
directors to Lyondell and its stockholders for monetary damages resulting from
some breaches of the directors' fiduciary duties. Article VII of the
Certificate of Incorporation provides as follows:

   To the fullest extent permitted by the General Corporation Law of Delaware
as the same exists or may hereafter be amended, a director of Lyondell will not
be liable to Lyondell or its stockholders for monetary damages for breach of
fiduciary duty as a director. If the General Corporation Law of Delaware is
amended to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of Lyondell
will be eliminated or limited to the fullest extent permitted by the General
Corporation Law of Delaware, as so amended. Any repeal or modification of this
Article VII by the stockholders of Lyondell will not adversely affect any right
or protection of a director of Lyondell existing at the time of such repeal or
modification or with respect to events occurring prior to such time.
Notwithstanding anything contained in Lyondell's Certificate of Incorporation
to the contrary, the affirmative vote of the holders of not less than 66 2/3
percent of all votes entitled to be cast by the holders of stock of Lyondell
will be required to amend or repeal this Article VII or to adopt any provision
inconsistent herewith.

                                      II-3
<PAGE>

   Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a corporation's Certificate of Incorporation may contain the
following:

   (7) A provision eliminating or limiting the personal liability of a director
to the corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, provided that such provision will not eliminate
or limit the liability of a director:

     .for any breach of the director's duty of loyalty to the corporation or
  its stockholders;

    . for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

     .under section 174 of this title; or

     .for any transaction from which the director derived an improper
  personal benefit.

No such provision will eliminate or limit the liability of a director for any
act or omission occurring prior to the date when such provision becomes
effective. All references in this paragraph to a director will also be deemed
to refer (x) to a member of the governing body of a corporation which is not
authorized to issue capital stock, and (y) to such other person or persons, if
any, who, pursuant to a provision of the certificate of incorporation in
accordance with section 141(a) of this title, exercise or perform any of the
powers or duties otherwise conferred or imposed upon the board of directors by
this title.

Lyondell Worldwide

   Lyondell Worldwide's Certificate of Incorporation limits the personal
liability of directors for monetary damages resulting from some breaches of
directors' fiduciary duties. Article IX of the Certificate of Incorporation
provides as follows:

     To the fullest extent permitted by the General Corporation Law of
  Delaware as the same exists or may hereafter be amended, a director of the
  Company will not be liable to the Company or its stockholders for monetary
  damages for breach of fiduciary duty as a director. If the General
  Corporation Law of Delaware is amended after approval by the stockholders
  of this provision to authorize corporate action further eliminating or
  limiting the personal liability of directors, then the liability of a
  director of the Company will be eliminated or limited to the fullest extent
  permitted by the General Corporation Law of Delaware, as so amended. Any
  repeal or modification of this Article IX by the stockholders of the
  Company will not adversely affect any right or protection of a director of
  the Company existing at the time of such repeal or modification or with
  respect to events occurring prior to such time. Notwithstanding anything
  contained in this Certificate to the contrary, the affirmative vote of the
  holders of not less than 66 2/3 percent of all votes entitled to be cast by
  the holders of stock of the Company will be required to amend or repeal
  this Article IX or to adopt any provision inconsistent herewith.

ITEM 22. Undertakings

  1. The undersigned co-registrants hereby undertake:

    . to file, during any period in which offers or sales are being made, a
      post-effective amendment to this registration statement to

      --include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933

      --include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement
       or any material change to information in the registration statement

      --reflect in the prospectus any facts or events arising after the
       effective date of the registration statement or its most recent
       post-effective amendment which, individually or in the aggregate,
       represent a fundamental change in the information shown in the
       registration statement.

       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 the SEC under Rule 424(b) of the Securities
       Act if, in the aggregate, the changes in volume and price represent
       no more than a 20% change in the maximum aggregate offering price
       stated in the "Calculation of Registration Fee" table in the
       effective registration statement

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

    . 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

  2. The undersigned co-registrants hereby undertake that, for purposes of
     determining any liability under the Securities Act of 1933, each filing
     of the registrants' annual report under section 13(a) or section 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 Securities Exchange Act of 1934) that is incorporated by
     reference in the registration statement will be deemed to be a new
     registration statement relating to the securities offered therein, and
     the offering of such securities at that time will be deemed to be the
     initial bona fide offering.

  3. Insofar as indemnification for liabilities arising under the Securities
     Act of 1933 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
     Securities and Exchange SEC such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other
     than the payment by the registrant of expenses incurred or paid by a
     director, officer or controlling person of the registrant 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 its counsel the matter has been settled by controlling precedent,
     submit to a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act
     and will be governed by the final adjudication of such issue.

stated and any notice so required shall be deemed to be sufficient if given by
depositing the same in a post office box in a sealed post-paid wrapper,
addressed to the person entitled thereto at his last known post office address,
and such notice shall be deemed to have been given on the day of such mailing.
Stockholders not entitled to vote shall not be entitled to receive notice of any
meetings except as otherwise provided by the DGCL.

     Section 2.  Holders.

     A Person is deemed to be a holder of Transfer Restricted Securities (each,

     Section 3.  Registered Exchange Offers.

     (a)  Unless an Exchange Offer shall not be permitted by applicable federal
law (after the procedures set forth in Section 6(a)(i) below have been complied
with), the Company and the Guarantors shall (i) cause the Exchange Offer
Registration Statement with respect to each series of Initial Notes to be filed
with the Commission as soon as practicable after the Closing Date, but in no
event later than 90 days after the Closing Date (such 90th day being the "Filing
Deadline"), (ii) use their best efforts to cause such Exchange Offer
Registration Statement to become effective at the earliest possible time, but in
no event later than 210 days after the Closing Date (such 210th day being the
"Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the Exchange Notes to be
made under the Blue Sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer, and (iv) upon the effectiveness of such
Exchange Offer Registration Statement and within the time period contemplated by
Section 3(b) hereof, commence and Consummate the Exchange Offer with respect to
each series of Initial Notes. Each Exchange Offer shall be on the appropriate
form permitting (i) registration of the Exchange Notes to be offered in exchange
for the Initial Notes that are Transfer Restricted Securities and (ii) resales
of Exchange Notes by Broker-Dealers that tendered into the Exchange Offer
Initial Notes that such Broker-Dealer acquired for its own account as a result
of market making activities or other trading activities (other than Initial
Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

     (b)  The Company and the Guarantors shall use their respective best efforts
to cause the Exchange Offer Registration Statement to be effective continuously,
and shall keep the Exchange Offer with respect to each series of Initial Notes
open for a period of not less than the minimum period required under

                                       5
<PAGE>

applicable federal and state securities laws to Consummate such Exchange Offer;
provided, however, that in no event shall such period be less than 20 Business
Days. The Company and the Guarantors shall cause the Exchange Offers to comply
with all applicable federal and state securities laws. No securities other than
the Exchange Notes shall be included in the Exchange Offer Registration
Statement. The Company and the Guarantors shall use their respective best
efforts to cause the Exchange Offer with respect to each series of Initial Notes
to be Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30
business days thereafter (such 30th day being the "Consummation Deadline").

     (c)  The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Initial Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer.  Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement.  See the Shearman & Sterling no-action letter (available
July 2, 1993).

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Exchange
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement.  To the extent necessary to ensure that the Prospectus
contained in the Exchange Offer Registration Statement is available for sales of
Exchange Notes by Broker-Dealers, the Company and the Guarantors agree to use
their respective best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Sections 6(a) and 6(c) hereof and in conformity
with the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
180 days from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto or are no longer outstanding.  The Company and
the Guarantors shall provide sufficient copies of the latest version of such
Prospectus

                                       6
<PAGE>

to such Broker-Dealers, promptly upon request, and in no event later than one
day after such request, at any time during such period.

     Section 4.  Shelf Registration.

     (a)  Shelf Registration.  If (i) an Exchange Offer is not permitted by
applicable law (after the Company and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the Consummation Deadline that (A) such Holder was prohibited by law or
Commission policy from participating in the applicable Exchange Offer or (B)
such Holder may not resell the Exchange Notes acquired by it in the applicable
Exchange Offer to the public without delivering a prospectus and the Prospectus
contained in the Exchange Offer Registration Statement is not appropriate or
available for such resales by such Holder or (C) such Holder is a Broker-Dealer
and holds Initial Notes acquired directly from the Company or any of its
Affiliates, then the Company and the Guarantors shall:

     (x)  cause to be filed, on or prior to 30 days after the earlier of (i) the
date on which the Company determines that the Exchange Offer Registration
Statement cannot be filed as a result of clause 4(a)(i) above and (ii) the date
on which the Company receives the notice specified in clause 4(a)(ii) above,
(such earlier date, the "Filing Deadline"), a shelf registration statement
pursuant to Rule 415 under the Act (which may be an amendment to the Exchange
Offer Registration Statement (the "Shelf Registration Statement")), relating to
(1) all Transfer Restricted Securities of each series of Initial Notes with
respect to which an Exchange Offer is not permitted in the case of clause
4(a)(i) above or (2) the Transfer Restricted Securities specified in any notice
in the case of clause 4(a)(ii), and

     (y)  shall use their respective best efforts to cause such Shelf
Registration Statement to become effective on or prior to 60 days after the
Filing Deadline for the Shelf Registration Statement (such 60th day the
"Effectiveness Deadline").

     If, after the Company has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Company is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e., clause
4(a)(i) above), then the filing of the Exchange Offer Registration Statement
shall be deemed to satisfy the requirements of clause (x) above; provided that,
in such event, the Company shall remain obligated to meet the Effectiveness
Deadline set forth in clause (y).

                                       7
<PAGE>

     To the extent necessary to ensure that the Shelf Registration Statement is
available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Company and
the Guarantors shall use their respective best efforts to keep any Shelf
Registration Statement required by this Section 4(a) continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Sections 6(b) and 6(c) hereof and in conformity with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years (as extended
pursuant to Section 6(d)) following the Closing Date, or such shorter period as
will terminate on the earlier of the date when all Transfer Restricted
Securities covered by such Shelf Registration Statement have been sold pursuant
thereto, no longer constitute Transfer Restricted Securities or are no longer
outstanding.

     (b)  Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement.  No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  No Holder of Transfer
Restricted Securities shall be entitled to Liquidated Damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information which is required by rules of the Commission to be included in the
Shelf Registration Statement prior to the time it is declared effective.  Each
selling Holder agrees to promptly furnish additional information required to be
disclosed in order to make the information previously furnished to the Company
by such Holder not materially misleading.

     (c)  Suspension.  The Company and the Guarantors will have the ability to
suspend the Shelf Registration Statement (a "Suspension Period"), if the Company
and the Guarantors determine, in their reasonable best judgment, upon written
advice of counsel, that the continued effectiveness and use of the Shelf
Registration Statement would require the disclosure of confidential information
or interfere with any financing, acquisition, reorganization or other material
transaction involving the Company.  A Suspension Period shall commence on and
include the date that the Company and the Guarantors give notice that the Shelf
Registration Statement is no longer effective or the Prospectus included therein
is no longer usable for offers and sales of Transfer Restricted Securities
covered by such Registration Statement and continue until holders of such
Transfer Restricted Securities either receive the copies of the supplemented or
amended prospectus contemplated by Section 6(c) hereof or are advised in writing
by the Company

                                       8
<PAGE>

and the Guarantors that use of the Prospectus may be resumed. Any such
suspensions may not exceed (i) 60 days in the aggregate in the first twelve
month period after the Closing Date, (ii) 60 days in the aggregate in the twelve
month period immediately thereafter and (iii) 90 days in the aggregate during
any subsequent twelve month period.

     Section 5.  Liquidated Damages.

     If (a) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (b) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (c) the Exchange Offer with
respect to any series of Initial Notes has not been Consummated on or prior to
the Consummation Deadline or (d) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable (provided that the unavailability of a
Registration Statement for the use of a Holder as a result of such Holder's
failure to provide information pursuant to Section 4(b) or make representations
required by Section 6(a)(ii) shall not be deemed to make the Registration
Statement fail to be usable) for its intended purpose (except as provided in,
and during the time periods specified in, Section 4(c)) without being succeeded
within five days by a post-effective amendment to such Registration Statement
that cures such failure and that is itself declared effective within 10 days of
the filing of such post-effective amendment (each such event referred to in
clauses  (a) through (d), a "Registration Default"), then the Company and each
of the Guarantors hereby jointly and severally agree to pay to each Holder of
Transfer Restricted Securities affected thereby liquidated damages in an amount
equal to $.05 per week per $1,000 in principal amount of Transfer Restricted
Securities held by such Holder for each week or portion thereof that the
Registration Default continues for the first 90-day period immediately following
the occurrence of such Registration Default.  The amount of the liquidated
damages shall increase by an additional $.05 per week per $1,000 in principal
amount of Transfer Restricted Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum amount
of liquidated damages of $.50 per week per $1,000 in principal amount of
Transfer Restricted Securities; provided that the Company and the Guarantors
shall in no event be required to pay liquidated damages with respect to a series
of Notes for more than one Registration Default at any given time.
Notwithstanding anything to the contrary set forth herein, (i) upon filing of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of clause (a) above, (ii) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of clause (b) above,
(iii) upon Consummation of the Exchange Offer, in the case of clause (c) above,
or (iv) upon the filing of a post-effective amendment to the Registration
Statement or an additional

                                       9
<PAGE>

Registration Statement that causes the Exchange Offer Registration Statement
(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of clause (d) above, in each case with
respect to the applicable series of Notes, the liquidated damages payable with
respect to the Transfer Restricted Securities of such series of Notes as a
result of such clause (a), (b), (c) or (d), as applicable, shall cease to
accrue.

     All accrued liquidated damages shall be paid to the record Holders entitled
thereto, in the manner provided for the payment of interest in the applicable
Indenture, on each Interest Payment Date, as more fully set forth in the
applicable Indenture and the Notes.  Notwithstanding the fact that any
securities for which liquidated damages are due cease to be Transfer Restricted
Securities, all obligations of the Company and the Guarantors to pay liquidated
damages with respect to securities shall survive until such time as such
obligations with respect to such securities shall have been satisfied in full.

     Section 6.  Registration Procedures.

     (a)  Exchange Offer Registration Statement.  In connection with the
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Exchange Notes by
Broker-Dealers that tendered in the Exchange Offer Initial Notes that such
Broker-Dealer acquired for its own account as a result of its market making
activities or other trading activities (other than Initial Notes acquired
directly from the Company or any of its Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply with
all of the following provisions:

     (i)  If, following the date hereof there has been announced a change in
Commission policy with respect to exchange offers such as the Exchange Offer,
that in the reasonable opinion of counsel to the Company raises a substantial
question as to whether the Exchange Offer is permitted by applicable federal
law, the Company and the Guarantors hereby agree to seek a no-action letter or
other favorable decision from the Commission allowing the Company and the
Guarantors to Consummate an Exchange Offer for such Transfer Restricted
Securities.  The Company and the Guarantors hereby agree to pursue the issuance
of such a decision to the Commission staff level but shall not be required to
take commercially unreasonable action to effect a change of Commission policy.
In connection with the foregoing, the Company and the Guarantors hereby agree to
take all such other actions (other than such actions as may be commercially
unreasonable) as may be requested by the Commission or otherwise required in
connection with the issuance of such decision,

                                      10
<PAGE>

including without limitation (A) participating in telephonic conferences with
the Commission, (B) delivering to the Commission staff an analysis prepared by
counsel to the Company setting forth the legal bases, if any, upon which such
counsel has concluded that such an Exchange Offer should be permitted and (C)
diligently pursuing a resolution (which need not be favorable) by the Commission
staff.

     (ii) As a condition to its participation in the Exchange Offer, each Holder
of Transfer Restricted Securities (including, without limitation, any Holder who
is a Broker Dealer) shall furnish, upon the request of the Company, prior to the
Consummation of the Exchange Offer, a written representation to the Company and
the Guarantors (which may be contained in the letter of transmittal contemplated
by the Exchange Offer Registration Statement) to the effect that (A) that such
Holder is not an Affiliate of the Company or a Broker-Dealer tendering Initial
Notes acquired directly from the Company for its own account, (B) such Holder
will have no arrangement or understanding with any person to participate in the
distribution of the Initial Notes or the Exchange Notes within the meaning of
the Act, (C)  if the Holder is not a Broker-Dealer or is a Broker-Dealer but
will not receive Exchange Notes for its own account in exchange for Initial
Notes, neither the Holder nor any such other Person is engaged in or intends to
participate in a distribution of the Exchange Notes, and (D) any Exchange Notes
received by such Holder will be acquired in the ordinary course of its business.
If the Holder is a Broker-Dealer that will receive Exchange Notes for its own
account in exchange for Initial Notes, it will represent that the Initial Notes
to be exchanged for the Exchange Notes were acquired by it as a result of
market-making activities or other trading activities, and will acknowledge that
it will deliver a prospectus meeting the requirements of the Act in connection
with any resale of such Exchange Notes.  It is understood that, by acknowledging
that it will deliver, and by delivering, a prospectus meeting the requirements
of the Act in connection with any resale of such Exchange Notes, the Holder is
not admitting that it is an "underwriter" within the meaning of the Act.

     (iii)  Prior to effectiveness of the Exchange Offer Registration Statement,
the Company and the Guarantors shall provide a supplemental letter to the
Commission (A) stating that the Company and the Guarantors are registering the
Exchange Offer in reliance on the position of the Commission enunciated in Exxon
Capital Holdings Corporation (available May 13, 1988), Morgan Stanley and Co.,
Inc. (available June 5, 1991) as interpreted in the Commission's letter to
Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action letter
obtained pursuant to Section 6(a)(i) above, (B) including a representation that

                                      11
<PAGE>

neither the Company nor any of the Guarantors has entered into any arrangement
or understanding with any Person to distribute the Exchange Notes to be received
in the Exchange Offer and that, to the best of the Company's and each
Guarantor's information and belief, each Holder participating in the Exchange
Offer is acquiring the Exchange Notes in its ordinary course of business and has
no arrangement or understanding with any Person to participate in the
distribution of the Exchange Notes received in the Exchange Offer and (C) any
other undertaking or representation required by the Commission as set forth in
any no-action letter obtained pursuant to Section 6(a)(i) above, if applicable.

     (b)  Shelf Registration Statement.  In connection with the Shelf
Registration Statement, the Company and the Guarantors shall

     (i)  comply with all the provisions of Section 6(c) below and use their
respective reasonable best efforts to effect such registration to permit the
sale of the Transfer Restricted Securities being sold in accordance with the
intended method or methods of distribution thereof (as indicated in the
information furnished to the Company pursuant to Section 4(b) hereof), and
pursuant thereto the Company and the Guarantors will prepare and file with the
Commission a Registration Statement relating to the registration on any
appropriate form under the Act, which form shall be available for the sale of
the Transfer Restricted Securities in accordance with the intended method or
methods of distribution thereof within the time periods and otherwise in
accordance with the provisions hereof, and

     (ii) issue, upon the request of any Holder or purchaser of Initial Notes
covered by any Shelf Registration Statement contemplated by this Agreement,
Exchange Notes having an aggregate principal amount equal to the aggregate
principal amount of Initial Notes sold pursuant to the Shelf Registration
Statement and surrendered to the Company for cancellation; the Company shall
register Exchange Notes on the Shelf Registration Statement for this purpose and
issue the Exchange Notes to the purchaser(s) of securities subject to the Shelf
Registration Statement in the names as such purchaser(s) shall designate.

     (c)  General Provisions.  In connection with any Registration Statement and
any related Prospectus required by this Agreement, the Company and the
Guarantors shall:

     (i)  use their respective best efforts to keep such Registration Statement
continuously effective and provide all requisite financial statements for the
period specified in Section 3 or 4 of this Agreement, as applicable.  Upon the
occurrence of any event that would cause any such

                                      12
<PAGE>

Registration Statement or the Prospectus contained therein (A) to contain an
untrue statement of material fact or omit to state any material fact necessary
to make the statements therein not misleading or (B) not to be effective and
usable for resale of Transfer Restricted Securities during the period required
by this Agreement, the Company and the Guarantors shall file promptly an
appropriate amendment to such Registration Statement curing such defect, and, if
Commission review is required, use their respective reasonable best efforts to
cause such amendment to be declared effective as soon as practicable.

     (ii)  prepare and file with the Commission such amendments and post-
effective amendments to the applicable Registration Statement as may be
necessary to keep such Registration Statement effective for the applicable
period set forth in Section 3 or 4 hereof, as the case may be; cause the
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the Act, and to comply fully
with Rules 424, 430A and 462, as applicable, under the Act in a timely manner;
and comply with the provisions of the Act with respect to the disposition of all
securities covered by such Registration Statement during the applicable period
in accordance with the intended method or methods of distribution by the sellers
thereof set forth in such Registration Statement or supplement to the
Prospectus;

     (iii) advise the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, promptly and,
if requested by such Holder, confirm such advice in writing, (A) when the
Prospectus or any Prospectus supplement or post-effective amendment has been
filed, and, with respect to any applicable Registration Statement or any post-
effective amendment thereto, when the same has become effective, (B) of any
request by the Commission for amendments to the Registration Statement or
amendments or supplements to the Prospectus or for additional information
relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement under the Act or of
the suspension by any state securities commission of the qualification of the
Transfer Restricted Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, and (D) of the
existence of any fact or the happening of any event that makes any statement of
a material fact made in the Registration Statement, the Prospectus, any
amendment or supplement thereto or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the Registration Statement in order to make the statements therein not
misleading, or that requires the making of any additions to or changes in the
Prospectus in order to make the statements

                                      13
<PAGE>

therein, in the light of the circumstances under which they were made, not
misleading. If at any time the Commission shall issue any stop order suspending
the effectiveness of the Registration Statement, or any state securities
commission or other regulatory authority shall issue an order suspending the
qualification or exemption from qualification of the Transfer Restricted
Securities under state securities or Blue Sky laws, the Company and the
Guarantors shall use their respective best efforts to obtain the withdrawal or
lifting of such order at the earliest possible time;

     (iv)  subject to Section 6(c)(i), if any fact or event contemplated by
Section 6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or
post-effective amendment to the Registration Statement or related Prospectus or
any document incorporated therein by reference or file any other required
document so that, as thereafter delivered to the purchasers of Transfer
Restricted Securities, the Prospectus will not contain an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading;

     (v)  furnish to the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, if any, before filing with the Commission, copies of
any Registration Statement or any Prospectus included therein or any amendments
or supplements to any such Registration Statement or Prospectus (including all
documents incorporated by reference after the initial filing of such
Registration Statement), which documents will be subject to the review and
comment of such Holders in connection with such sale, if any, for a period of at
least five Business Days, and the Company will not file any such Registration
Statement or Prospectus or any amendment or supplement to any such Registration
Statement or Prospectus (including all such documents incorporated by reference)
to which such Holders shall reasonably object within five Business Days after
the receipt thereof.  A Holder  shall be deemed to have reasonably objected to
such filing if such Registration Statement, amendment, Prospectus or supplement,
as applicable, as proposed to be filed, contains an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading or fails to comply with the applicable
requirements of the Act;

     (vi)  promptly prior to the filing of any document that is to be
incorporated by reference into a Registration Statement or Prospectus, provide
copies of such document to the Initial Purchasers and in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, if any, make the

                                      14
<PAGE>

Company's and each Guarantor's representatives available for discussion of such
document and other customary due diligence matters, and include such information
in such document prior to the filing thereof as the Initial Purchasers or such
Holders may reasonably request;

     (vii)  make available, at reasonable times, for inspection by the Initial
Purchasers and, in the case of a Shelf Registration Statement, each Holder of
securities covered thereby, and the designated counsel or any accountant
retained by such Holders, all financial and other records, pertinent corporate
documents of the Company and each Guarantor and cause the Company's and each
Guarantor's officers, directors and employees to supply all information
reasonably requested by any such Initial Purchaser, Holder, attorney or
accountant in connection with such Registration Statement or any post-effective
amendment thereto subsequent to the filing thereof and prior to its
effectiveness; provided, however, that such persons shall first agree in writing
with the Company and the Guarantors that any information that is reasonably and
in good faith designated by the Company and the Guarantors in writing as
confidential at the time of delivery of such information shall be kept
confidential by such persons, unless (i) disclosure of such information is
required by court or administrative order or is necessary to respond to
inquiries of regulatory authorities, (ii) disclosure of such information is
required by law (including any disclosure requirements pursuant to federal
securities laws in connection with the filing of such Registration Statement or
the use of any Prospectus), (iii) such information becomes generally available
to the public other than as a result of a disclosure or failure to safeguard
such information by such person or (iv) such information becomes available to
such person from a source other than the Company and its subsidiaries and such
source is not known, after due inquiry, by such person to be bound by a
confidentiality agreement; provided further, that the foregoing investigation
shall be coordinated on behalf of such persons by one representative designated
by and on behalf of such persons and any such confidential information shall be
available from such representative to such persons so long as any person agrees
to be bound by such confidentiality agreement;

     (viii)  if requested by the Initial Purchasers and, in the case of a Shelf
Registration Statement, any Holders of securities covered thereby, in connection
with such exchange or sale, promptly include in any Registration Statement or
Prospectus, pursuant to a supplement or post-effective amendment if necessary,
such information as such Persons may reasonably request to have included
therein, including, without limitation, information relating to the "Plan of
Distribution" of the Transfer Restricted Securities; and make all required
filings of such Prospectus

                                      15
<PAGE>

supplement or post-effective amendment as soon as practicable after the Company
is notified of the matters to be included in such Prospectus supplement or post-
effective amendment;

     (ix)  furnish to the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, without charge, at least one copy of the
Registration Statement, as first filed with the Commission, and of each
amendment thereto, including all documents incorporated by reference therein and
all exhibits (including exhibits incorporated therein by reference);

     (x)  deliver to each Holder without charge, as many copies of the
Prospectus (including each preliminary prospectus) and any amendment or
supplement thereto as such Persons reasonably may request; the Company and the
Guarantors hereby consent to the use (in accordance with law) of the Prospectus
and any amendment or supplement thereto by each selling Holder in connection
with the offering and the sale of the Transfer Restricted Securities covered by
the Prospectus or any amendment or supplement thereto;

     (xi)  in the case of a Shelf Registration Statement, enter into such
agreements (including underwriting agreements) and, the case of any Registration
Statement contemplated by this Agreement, make such representations and
warranties and take all such other actions in connection therewith in order to
expedite or facilitate the disposition of the Transfer Restricted Securities
pursuant to any applicable Registration Statement contemplated by this Agreement
as may be reasonably requested by any Initial Purchaser or, in the case of a
Shelf Registration Statement, the Holders of a majority in aggregate principal
amount of the Transfer Restricted Securities covered thereby (the "Majority
Holders") in connection with any sale or resale pursuant to any applicable
Registration Statement.  In such connection, the Company shall:

     (A)  upon request of the Majority Holders (in the case of a Shelf
Registration Statement) or any Initial Purchaser (in the case of an Exchange
Offer), furnish (or in the case of Sections 6(c)(xi)(A)(2) and 6(c)(xi)(A)(3),
use its best efforts to cause to be furnished) to each Holder upon Consummation
of the Exchange Offer or upon the effectiveness of the Shelf Registration
Statement, as the case may be:

     (1)  a certificate, dated such date, signed on behalf of the Company and
each Guarantor by (x) the President or

                                      16
<PAGE>

any Vice President and (y) a principal financial or accounting officer of the
Company and the Guarantor, confirming, as of the date thereof, the matters set
forth in Sections 6(d), 9(a) and 9(b) of the Purchase Agreement and such other
similar matters as may be reasonably requested;

     (2)  an opinion, dated the date of Consummation of the Exchange Offer or
the date of effectiveness of the Shelf Registration Statement, as the case may
be, of counsel for the Company and the Guarantors covering matters similar to
those set forth in paragraphs (e), (f) and (g) of Section 9 of the Purchase
Agreement and such other matter as may be reasonably requested, and in any event
including a statement to the effect that such counsel has participated in
conferences with officers and other representatives of the Company and the
Guarantors, representatives of the independent public accountants for the
Company and the Guarantors and have considered the matters required to be stated
therein and the statements contained therein, although such counsel has not
independently verified the accuracy, completeness or fairness of such
statements; and that such counsel advises that, on the basis of the foregoing
(relying as to materiality to the extent such counsel deems appropriate upon the
statements of officers and other representatives of the Company and the
Guarantors and without independent check or verification), no facts came to such
counsel's attention that caused such counsel to believe that the applicable
Registration Statement, at the time such Registration Statement or any post-
effective amendment thereto became effective and, in the case of the Exchange
Offer Registration Statement, as of the date of Consummation of the Exchange
Offer, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or that the Prospectus contained in such Registration
Statement as of its date and, in the case of the opinion dated the date of
Consummation of the Exchange Offer, as of the date of Consummation, contained an
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  Without limiting the
foregoing, such counsel may state further that such

                                      17
<PAGE>

counsel assumes no responsibility for, and has not independently verified, the
accuracy, completeness or fairness of the financial statements, notes and
schedules and other financial data included in any Registration Statement
contemplated by this Agreement or the related Prospectus; and

     (3)  a customary comfort letter, dated the date of Consummation of the
Exchange Offer, or as of the date of effectiveness of the Shelf Registration
Statement, as the case may be, from the Company's independent accountants, in
the customary form and covering matters of the type customarily covered in
comfort letters to underwriters in connection with underwritten offerings, and
affirming the matters set forth in the comfort letters delivered pursuant to
Section 9(j) of the Purchase Agreement; and

     (B)  deliver such other documents and certificates as may be reasonably
requested by any of the Initial Purchasers or, in the case of any Shelf
Registration Statement, the Majority Holders,  to evidence compliance with the
matters covered in Section 6(c)(xi)(A) above and with any customary conditions
contained in any agreement entered into by the Company and the Guarantors
pursuant to this Section 6(c)(xi);

     (xii)  prior to any public offering of Transfer Restricted Securities,
cooperate with the Holders named in the applicable Registration Statement (or
any prospectus supplement thereto) and their counsel in connection with the
registration and qualification of the Transfer Restricted Securities under the
securities or Blue Sky laws of such jurisdictions as any such Holders may
request and do any and all other acts or things necessary or advisable to enable
the disposition in such jurisdictions of the Transfer Restricted Securities
covered by the applicable Registration Statement; provided, however, that
neither the Company nor any Guarantor shall be required to register or qualify
as a foreign corporation where it is not now so qualified or to take any action
that would subject it to the service of process in suits or to taxation, other
than as to matters and transactions relating to the Registration Statement, in
any jurisdiction where it is not now so subject;

     (xiii)  in connection with any sale of Transfer Restricted Securities that
will result in such securities no longer being Transfer Restricted Securities,
cooperate with the Holders to facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to

                                      18
<PAGE>

be sold and not bearing any restrictive legends; and, subject to the provisions
of the Indenture regarding global securities, to register such Transfer
Restricted Securities in such denominations and such names as the selling
Holders may request at least two Business Days prior to such sale of Transfer
Restricted Securities;

     (xiv)  use their respective best efforts to cause the disposition of the
Transfer Restricted Securities covered by the Registration Statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to enable the seller or sellers thereof to consummate the
disposition of such Transfer Restricted Securities, subject to the proviso
contained in Section 6(c)(xii) above;

     (xv)  provide a CUSIP number for all Transfer Restricted Securities not
later than the effective date of a Registration Statement covering such Transfer
Restricted Securities and provide the Trustee under the applicable Indenture
with printed certificates for the Transfer Restricted Securities which are in a
form eligible for deposit with the Depository Trust Company;

     (xvi)  otherwise use their respective best efforts to comply with all
applicable rules and regulations of the Commission, and make generally available
to its security holders with regard to any applicable Registration Statement, as
soon as practicable, a consolidated earnings statement meeting the requirements
of Rule 158 (which need not be audited) covering a twelve-month period beginning
after the effective date of the Registration Statement (as such term is defined
in paragraph (c) of Rule 158 under the Act);

     (xvii) cause the Indentures to be qualified under the TIA not later than
the effective date of the first Registration Statement required by this
Agreement and, in connection therewith, cooperate with the Trustee and the
Holders to effect such changes to the Indentures as may be required for such
Indentures to be so qualified in accordance with the terms of the TIA; and
execute and use its best efforts to cause the Trustee to execute, all documents
that may be required to effect such changes and all other forms and documents
required to be filed with the Commission to enable such Indentures to be so
qualified in a timely manner; and

     (xviii)  provide promptly to each Holder, upon request, each document filed
with the Commission pursuant to the requirements of Section 13 or Section 15(d)
of the Exchange Act.

                                      19
<PAGE>

     (d)  Restrictions on Holders.  Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 4(c) or Section 6(c)(iii)(C) or any notice from the Company of the
existence of any fact of the kind described in Section 6(c)(iii)(D) hereof (in
each case, a "Suspension Notice"), such Holder will forthwith discontinue
disposition of Transfer Restricted Securities pursuant to the applicable
Registration Statement until (i) such Holder has received copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof, or
(ii) such Holder is advised in writing by the Company that the use of the
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus (in
each case, the "Recommencement Date").  Each Holder receiving a Suspension
Notice hereby agrees that it will either (i) destroy any Prospectuses, other
than permanent file copies, then in such Holder's possession which have been
replaced by the Company with more recently dated Prospectuses or (ii) deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies, then in such Holder's  possession of the Prospectus covering such
Transfer Restricted Securities that was current at the time of receipt of the
Suspension Notice.  The time period regarding the effectiveness of such
Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall
be extended by a number of days equal to the number of days in the period from
and including the date of delivery of the Suspension Notice to the date of
delivery of the Recommencement Date.

     No holder may participate in any underwritten registration under the
Agreement unless such Holder (a) agrees to sell such Holder's Transfer
Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled under this Agreement to approve such
arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorneys, indemnities, underwriting agreements, lock-up letters and
other documents required under the terms of such underwriting arrangements.

     Section 7.  Registration Expenses.

     (a) All expenses incident to the Company's and the Guarantors' performance
of or compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including without

officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company or any Guarantor.

     (b)  In connection with any Registration Statement required by this

Statement and the Shelf Registration Statement), the Company and the Guarantors
will reimburse the Initial Purchasers and the Holders of Transfer Restricted
Securities who are tendering Initial Notes in the Exchange Offer and/or selling
or reselling Initial Notes or Exchange Notes pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be Davis Polk & Wardwell,
unless another firm shall be chosen by the Holders of a majority in principal
amount of the Transfer Restricted Securities for whose benefit such Registration
Statement is being prepared.

     Section 8.  Indemnification.

     (a)  The Company and each of the Guarantors agree, jointly and severally,
to indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all losses,
claims, damages, liabilities, judgments, (including without limitation, any
legal or other expenses incurred in connection with investigating or defending
any matter, including any action that could give rise to any such losses,
claims, damages, liabilities or judgments) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, preliminary prospectus or Prospectus (or any amendment or supplement
thereto) provided by the Company to any Holder or any prospective purchaser of
Exchange Notes or registered Initial Notes, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing to the Company
by any of the Holders provided, however, that the foregoing indemnity agreement
with respect

                                      21
<PAGE>

to the preliminary prospectus shall not inure to the benefit of any Holder who
failed to deliver the Prospectus, as then amended or supplemented (so long as
the Prospectus and any such amendment or supplement was provided by the Company
to the Holders in the requisite quantity and on a timely basis to permit proper
delivery) to the person asserting any losses, claims, damages, liabilities or
judgments caused by any untrue statement or alleged untrue statement of a
material fact contained in the preliminary prospectus, or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, if such
material misstatement or omission or alleged material misstatement or omission
was cured in the Prospectus, as so amended or supplemented.

     (b)  Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company and the Guarantors, and
their respective directors and officers, and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
the Company or the Guarantors to the same extent as the foregoing indemnity from
the Company and the Guarantors set forth in Section 8(a) above, but only with
reference to information relating to such Holder furnished in writing to the
Company by such Holder expressly for use in any Registration Statement,
preliminary prospectus or Prospectus (or any amendment or supplement thereto).
In no event shall any Holder, its directors, officers or any Person who controls
such Holder be liable or responsible for any amount in excess of the total
amount received by such Holder with respect to its sale of Transfer Restricted
Securities pursuant to a Registration Statement exceeds the amount of any
damages that such Holder, its directors, officers or any Person who controls
such Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

     (c)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment

                                      22
<PAGE>

of such counsel shall have been specifically authorized in writing by the
indemnifying party, (ii) the indemnifying party shall have failed to assume the
defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 8(a), and by
the Company and the Guarantors, in the case of parties indemnified pursuant to
Section 8(b). The indemnifying party shall indemnify and hold harmless the
indemnified party from and against any and all losses, claims, damages,
liabilities and judgments by reason of any settlement of any action (i) effected
with its written consent or (ii) effected without its written consent if the
settlement is entered into more than sixty days after the indemnifying party
shall have received a request from the indemnified party for reimbursement for
the fees and expenses of counsel (in any case where such fees and expenses are
at the expense of the indemnifying party) and more than twenty days after the
indemnifying party shall have received notice of the proposed settlement and,
prior to the date of such settlement, the indemnifying party shall have failed
to comply with such reimbursement request. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement or
compromise of, or consent to the entry of judgment with respect to, any pending
or threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

     (d)  To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments (i) in such proportion as is
appropriate to reflect the

                                      23
<PAGE>

relative benefits received by the Company and the Guarantors, on the one hand,
and the Holders, on the other hand, from their sale of Transfer Restricted
Securities or (ii) if the allocation provided by clause 8(d)(i) is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 8(d)(i) above but also the relative
fault of the Company and the Guarantors, on the one hand, and of the Holder, on
the other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative fault of the Company and the
Guarantors, on the one hand, and of the Holder, on the other hand, shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or the
Guarantors, on the one hand, or by the Holder, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company, the Guarantors and each Holder agree that it would not be just
and equitable if contribution pursuant to this Section 8(d) were determined by
pro rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments.  Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any Person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds the amount of
any damages which such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Holders' obligations to
contribute pursuant to this Section 8(d) are several in proportion to the
respective principal amount of Transfer Restricted Securities held by each
Holder hereunder and not joint.

     Section 9.  Rule 144A and Rule 144.

                                      24
<PAGE>

     The Company and each Guarantor agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding and during any period in which
the Company or any Guarantor (i) is not subject to Section 13 or 15(d) of the
Exchange Act, to make available, upon request of any Holder, to such Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

     Section 10.  Miscellaneous.

     (a)  Remedies.  The Company and the Guarantors  acknowledge and agree that
any failure by the Company and/or any Guarantor to comply with their respective
obligations under Sections 3 and 4 hereof may result in material irreparable
injury to the Initial Purchasers or the Holders for which there is no adequate
remedy at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, the Initial Purchasers or
any Holder  may obtain such relief as may be required to specifically enforce
the Company's and the Guarantors' obligations under Sections 3 and 4 hereof. The
Company and the Guarantors further agree to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     (b)  No Inconsistent Agreements.  Neither the Company nor any Guarantor
will, on or after the date of this Agreement, enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any Guarantor has previously entered into any agreement
which remains in effect granting any registration rights with respect to its
securities to any Person. The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's and the Guarantors' securities under any agreement in
effect on the date hereof.

     (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this clause 10(c)(i), the Company has obtained the written consent of
Holders of all outstanding Transfer Restricted Securities and (ii) in the case
of all other provisions hereof, the Company has obtained the written consent of
Holders of a majority of the outstanding principal amount of Transfer Restricted
Securities (excluding Transfer Restricted Securities held by the

                                      25
<PAGE>

Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

     (d)  Third Party Beneficiary.  The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders hereunder.

     (e)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

     (i)  if to a Holder, at the address set forth on the records of the
Registrar under the applicable  Indenture, with a copy to the Registrar under
such Indenture; and

     (ii)  if to the Company or the Guarantors:

               One Houston Center, Suite 700
               1221 McKinney Street
               Houston, Texas 77010

               Houston, Texas 77002
               Telecopier No.: 713-229-1522
               Attention: Steve Massad, Esq.

     All such notices and communications shall be deemed to have been duly
given:  at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when receipt

                                      26
<PAGE>

acknowledged, if telecopied; and on the next business day, if timely delivered
to an air courier guaranteeing overnight delivery.

     Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the applicable Trustee
at the address specified in the relevant Indenture.

     (f)  Successors and Assigns.  This Agreement shall inure to the benefit of
and be binding upon the successors and assigns of each of the parties, including
without limitation and without the need for an express assignment, subsequent
Holders; provided, that nothing herein shall be deemed to permit any assignment,
transfer or other disposition of Transfer Restricted Securities in violation of
the terms hereof or of the Purchase Agreement or the applicable Indenture.  If
any transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

     (g)  Counterparts.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

     (h)  Headings.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

     (i)  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
CONFLICT OF LAW RULES THEREOF.

     (j)  Severability.  In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

     (k)  Entire Agreement.  This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of

                                      27
<PAGE>

the subject matter contained herein.  There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted with respect to the Transfer
Restricted Securities.  This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

                                      28
<PAGE>

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.

in person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee, and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 7.01)
conclusive in favor of the Trustee, the Company and any other obligor upon the
Notes, if made in the manner provided in this Section 1.08.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership or
other entity, on behalf of such corporation or partnership or other entity, such
certificate or affidavit shall also constitute sufficient proof of such Person's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the person executing the same, may also be proved in any
other manner that the Trustee deems sufficient.

     (c)  The ownership of Notes shall be proved by the Register.

     (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Note shall bind the Holder of every Note
issued upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done or suffered to be done by the Trustee, the Company or
any other obligor on the Notes in reliance thereon, whether or not notation of
such action is made upon such Note.

     (e)  (i) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in Section
1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date (or their duly designated proxies), and
no other Holders, shall be entitled to take the relevant action, whether or not
such Persons remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date. Nothing in this

                                       32
<PAGE>

paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder in the manner set forth in Section 1.10.

     (ii)  The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to join in the giving or
making of (w) any Notice of Default, (x) any declaration of acceleration
referred to in Section 6.02, (y) any request to institute proceedings referred
to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each
case with respect to Notes. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Notes on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the expense of the Company, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be given to
the Company in writing and to each Holder in the manner set forth in Section
1.10.

     (iii) With respect to any record date set pursuant to this Section 1.08,
the party hereto that sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Company or the
Trustee, whichever such party is not setting a record date pursuant to this
Section 1.08(e) in writing, and to each Holder in the manner set forth in
Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     (iv)  Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Note may do so with regard to
all or any part of the principal amount of such Note or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     Section 1.09.  Notices, Etc., to Trustee and Company.  Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

     (a)  the Trustee by any Holder or by the Company or any other obligor upon
the Notes shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at the Corporate Trust
Office (telephone: (212) 815-6286; facsimile: (212) 815-5915), or at any other
address furnished in writing to the Company by the Trustee, or

     (b)  the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder if in writing and delivered in person or mailed, first-
class postage prepaid, to the Company at One Houston Center, Suite 700, 1221
McKinney, Houston, Texas 77010, Attention: General Counsel (facsimile: (713)
309-2143), with copies to Baker & Botts LLP at 910 Louisiana, Houston, Texas
77002, Attention: Steve Massad, Esq. (facsimile: (713) 229-1522), or at any
other address previously furnished in writing to the Trustee by the Company.

     Section 1.10.  Notices to Holders; Waivers.  Where this Indenture provides
for notice to Holders of any event, such notice shall be deemed to have been
given upon the mailing by first class mail, postage prepaid, of such notices to
Holders at their registered addresses as recorded in the Register, not later
than the latest date, and not earlier than the earliest date, prescribed herein
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail notice of any event as
required by any provision of this Indenture, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably
withheld) shall constitute a sufficient notification for every purpose
hereunder.

     Section 1.11.  Effect of Headings and Table of Contents.  The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 1.12. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its respective successors and assigns,
whether so expressed or not.

                                       34

     Section 1.13. Separability Clause. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 1.14.  Benefits of Indenture.  Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 1.15.  Governing Law.  THIS INDENTURE, THE NOTES AND THE SUBSIDIARY
GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY.  TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY,
THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY
THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THIS INDENTURE OR THE NOTES.

     Section 1.16. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest and Liquidated Damages, if any, or principal and premium (if any)
need not be made on such date, but may be made on the next succeeding Business
Day with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

     Section 1.17.  No Personal Liability of Directors, Officers, Employees,
Incorporators and Stockholders.  No director, officer, employee, incorporator,
shareholder or other holder of Equity Interests of the Company or the Subsidiary
Guarantors, as such, shall have any liability for any obligations of the Company
or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

     Section 1.18.  Exhibits and Schedules.  All exhibits and schedules attached
hereto are by this reference made a part hereof with the same effect as if
herein set forth in full.

     Section 1.19.  Counterparts.  This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

     Section 2.03.  Restrictive Legends.  (a) Except as set forth in Section
3.14(g), unless and until (i) an Initial Note or any Additional Note is sold
pursuant to an effective registration statement, whether pursuant to the

Additional Note is exchanged for an Exchange Note in an Exchange Offer pursuant
to an effective Exchange Offer Registration Statement pursuant to the
Registration Rights Agreement, each U.S. Global Note and U.S. Physical Note
shall bear the following legend set forth below (the "Private Placement Legend")
on the face thereof:

THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY
STATE OR OTHER JURISDICTION, AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS
ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

(1)  REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (As defined in
     Rule 144A under the Securities Act) (A "QIB")

(2)  AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A)
     TO THE COMPANY, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
     QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB TO WHOM

     OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND

(3)  AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST

     (b) Each Global Note, whether or not an Initial Note or Additional Note,
shall also bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR
THEIR AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY

AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE
TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR

HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH

                                   ARTICLE 3
                                   The Notes

     Section 3.01. Title and Terms. The aggregate principal amount of Notes that
may be authenticated and delivered and Outstanding under this Indenture is
initially limited to $900,000,000, but may be increased, subject to compliance
with the covenants contained in Article 4 below and the conditions set forth in
Section 3.03, and except as may be limited by applicable law; provided that the
aggregate principal amount of Senior Secured Notes outstanding at any time shall
not exceed $1.9 billion. The Initial Notes will

                                       38
<PAGE>

be issued in an aggregate principal amount of $900,000,000. All the Original
Notes shall vote and consent together on all matters as one class, and none of
the Original Notes will have the right to vote or consent as a class separate
from one another on any matter. Subject to the covenants contained in Article 4
below, the Company may issue Additional Notes hereunder. Additional Notes
(including any Exchange Notes issued in exchange therefor) shall vote (or
consent) as a class with the other Notes and otherwise be treated as Notes for
all purposes of this Indenture.

     The Notes shall be known and designated as the "9 5/8% Senior Secured
Notes, Series A, Due 2007" of the Company. The final Stated Maturity of the
Notes shall be May 1, 2007. Interest on the Outstanding principal amount of
Notes will accrue, subject to Section 3.11, at the rate of 9 5/8% per annum and
will be payable semiannually in arrears on May 1 and November 1 in each year,
commencing on November 1, 1999, to Holders of record at the close of business on
the immediately preceding April 15, and October 15, respectively (each such
April 15 and October 15 a "Regular Record Date"). Interest on the Original Notes
will accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid, from May 17, 1999, and interest
on any Additional Notes (and Exchange Notes issued in exchange therefor) will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid on such Additional Notes, from the
date of issuance of such Additional Notes; provided that if any Note is
surrendered for exchange on or after a record date for an Interest Payment Date
that will occur on or after the date of such exchange, interest on the Note
received in exchange thereof will accrue from the date of such Interest Payment
Date. The Company will pay interest on overdue principal and, to the extent
lawful, on overdue installments of interest and Liquidated Damages, if any, at a
rate of 1% per annum in excess of the interest rate referred to above.

     The principal of, and premium, if any, and interest and Liquidated Damages,
if any, on the Notes shall be payable at the Corporate Trust Office or at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York (each, a "Place of Payment") in the manner
provided in Section 4.01(b); provided, however, that, under the circumstances
set forth in Section 4.01(b), payment of interest and Liquidated Damages on a
Note may be made by wire transfer of immediately available funds to the account
specified by the Holder of a Global Note or by check mailed to the address of
the Person entitled thereto as such address shall appear in the Register.

     Section 3.02.  Denominations.  The Notes shall be issuable only in
registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof.

     Section 3.03. Execution, Authentication and Delivery and Dating. The Notes
shall be executed on behalf of the Company by an Officer of such Company. The
signature of such Officer on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signature of an individual who was at
any time a proper Officer of the Company shall bind the Company, notwithstanding
that such individual has ceased to hold such office prior to the authentication
and delivery of such Notes or did not hold such office at the date of such
Notes.

                                       39
<PAGE>

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes for original issue in the aggregate principal amount not to exceed
$900,000,000 and (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Company in the form of an Officer's
Certificate (an "Authentication Order"), and in the case of clause (ii), upon
receipt by the Trustee of an Opinion of Counsel confirming that the Holders of
the Outstanding Notes will be subject to federal income tax in the same amounts,
in the same manner and at the same times as would have been the case if such
Additional Notes were not issued. Such Officer's Certificates shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes, Additional Notes or
Exchange Notes, that, in the case of Additional Notes, (x) the issuance of such
Notes does not contravene any provision of Article 4 of this Indenture and (y)
after giving effect to such Issuance of Additional Notes, the aggregate
principal amount of Senior Secured Notes outstanding does not exceed $1.9
billion, whether the Notes are to be issued as one or more Global Notes or
Physical Notes, the name or names of the Initial Holder or Holders and such
other information as the Company may include or the Trustee may reasonably
request.

     All Notes shall be dated the date of their authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Note a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

     Section 3.04.  Temporary Notes.    Until definitive Notes are ready for
delivery, the Company may prepare and upon receipt of an Authentication Order
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company consider appropriate for temporary Notes. If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable
delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the
office or agency of the Company in a Place of Payment, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Company shall execute and upon receipt of an Authentication Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes of the same series and tenor.

     Section 3.05.  Registration, Registration of Transfer and Exchange.  The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Register") in

                                       40
<PAGE>

which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Notes and of transfers of Notes. The
Trustee is hereby appointed "Registrar" for the purpose of registering Notes and
transfers of Notes as herein provided.

     Upon surrender for transfer of any Note at the office or agency of the
Company in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes, of any authorized denominations and of a
like aggregate principal amount.

     At the option of the Holder, Notes may be exchanged for other Notes, of any
authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive; provided that no exchange of Initial Notes or
Initial Additional Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the SEC and the
Trustee shall have received an Officer's Certificate confirming that the
Exchange Offer Registration Statement has been declared effective by the SEC and
an exchange offer thereunder has been consummated.  The Initial Notes or
Additional Notes to be exchanged for the Exchange Notes shall be canceled by the
Trustee.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes under this
Section 3.05.

     Section 3.06.  Mutilated, Destroyed, Lost and Stolen Notes.  If (a) any
mutilated Note is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b)  there is delivered to the Company and the Trustee such security
or indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Company or the Trustee that such Note has been
acquired by a bona fide purchaser, the Company shall execute and upon receipt of
an Authentication Order the Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
Outstanding.

                                       41
<PAGE>

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and ratably with
any and all other Notes duly issued hereunder.

     The provisions of this Section 3.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     Section 3.07.  Payment of Interest Rights Preserved.  Interest and
Liquidated Damages on any Note that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest and Liquidated Damages
specified in Section 3.01.

     Any interest and Liquidated Damages on any Note that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder; and such Defaulted Interest shall be paid by the Company, as
provided in 3.07(a) or 3.07(b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Notes (or their respective Predecessor Notes) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as provided in this Section 3.07(a).  Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest,
the amount thereof and the Special Record Date and payment date therefor to be
mailed, first class postage prepaid, to each Holder at such Holder's address as
it appears in the

                                       42
<PAGE>

Register, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Notes (or their respective Predecessor Notes) are registered on
such Special Record Date and shall no longer be payable pursuant to the
following 3.07(b).

     (b)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause (b), such payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest (including
any Liquidated Damages) accrued and unpaid, and to accrue, that were carried by
such other Note.

     Section 3.08.  Persons Deemed Owners.   Prior to due presentment of a Note
for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of (and premium, if any, on) and (subject to Section 3.07) interest
and Liquidated Damages, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Company, the
Subsidiary Guarantors, the Trustee or any agent of the Company,  the Subsidiary
Guarantors or the Trustee shall be affected by notice to the contrary.

     Section 3.09. Cancellation. All Notes surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and, if not already canceled,
shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder that the Company may have acquired in any manner whatsoever, and all
Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes canceled as provided in
this Section 3.09, except as expressly permitted by this Indenture. All canceled
Notes held by the Trustee shall be disposed of in accordance with the Trustee's
customary procedures.

     Section 3.10.  Computation of Interest.  Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

     Section 3.11.  Payment of Liquidated Damages.  (a)  Under certain
circumstances the Company will be obligated to pay certain Liquidated Damages to
the Holders of certain Initial Notes, as more particularly set forth in such
Initial Notes.

     Section 3.12.  CUSIP Numbers.  The Company in issuing the Notes may use
"CUSIP" or "CINS" numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such "CUSIP" or "CINS" numbers in
addition to serial numbers in notices of redemption, repurchase or other notices
to Holders as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such "CUSIP" or "CINS"
numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Notes, and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the "CUSIP" or
"CINS" numbers.

     Section 3.13.  Book-entry Provisions for Global Notes.

     (a)  Each Global Note initially shall (i) be registered in the name of the
Depositary for such Global Notes or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) to the
extent relevant thereto, bear legends as set forth in Section 2.03.  None of the
Company or the Subsidiary Guarantors, nor any of their agents shall have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of beneficial ownership interests of, a Global Note, or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note, and the
Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Subsidiary
Guarantors, the Trustee or any agent of the Company, the Subsidiary Guarantors
or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a beneficial owner of any Note.  The registered Holder
of a Global Note may grant proxies and otherwise authorize any person, including
Agent Members and persons that may hold interests through Agent Members, to take
any action which a Holder is entitled to take under this Indenture or the Notes.

     (b)  Interests of beneficial owners in a Global Note may be transferred in
accordance with the applicable rules and procedures of the Depositary and the
provisions of Section 3.14.  Transfers of a Global Note shall be limited to
transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees, except (i) upon request of an Agent
Member (for itself or on behalf of a beneficial holder) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary
procedures of the Depositary and (ii) Physical Notes shall be transferred to
beneficial owners in exchange for their beneficial interests in the Global Notes
in the event that (A) the Depositary (1) notifies the Company that it is
unwilling or unable to continue as Depositary for the applicable Global Note and
a successor depositary is not appointed by the Company within 90 days or (2)
the Depositary ceases to be a "Clearing Agency" registered under the Exchange
Act , (B) the Company, at its option,

                                       44
<PAGE>

notifies the Trustee in writing that it elects to cause the issuance of Physical
Notes under this Indenture or (C) there shall have occurred and be continuing a
Default or Event of Default. In connection with any transfer or exchange of a
portion of the beneficial interest in any Global Note to beneficial owners for
Physical Notes pursuant to paragraph (b) of this Section 3.13, the Registrar
shall record on its books and records (and make a notation on the Global Note
of) the date and a decrease in the principal amount of such Global Note in an
amount equal to the beneficial interest in the Global Note being transferred,
and the Company shall execute, and the Trustee shall authenticate and deliver,
one or more Physical Notes of like tenor and principal amount of authorized
denominations. In connection with a transfer of an entire Global Note to
beneficial owners pursuant to clause (ii) of this paragraph (b), the applicable
Global Note shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall authenticate and deliver,
to each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the applicable Global Note, an equal aggregate principal
amount at maturity of Physical Notes of authorized denominations.

     (c) Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

     (d) The Company, the Subsidiary Guarantors, any other obligor upon the
Notes or the Trustee, in the discretion of any of them, may treat as the Act of
a Holder any instrument or writing of any Person that is identified by the
Depositary as the owner of a beneficial interest in the Global Note, provided
that the fact and date of the execution of such instrument or writing is proved
in accordance with Section 1.08(b).

     (e) Any U.S. Physical Note delivered in exchange for an interest in the
U.S. Global Note pursuant to paragraph (b) of this Section shall, except as
otherwise provided in Section 3.14, bear the Private Placement Legend.

144 under the Securities Act.

     (d)  Other Transfers. The Registrar shall effect and register, upon receipt

will duly and punctually pay the principal of (and premium, if any) and interest
and Liquidated Damages, if any, on the Notes in accordance with the terms of the

Liquidated Damages, if any) in respect of the Notes represented by the Global
Notes, the Holder of which has given wire transfer instructions on or prior to
the relevant record date, shall be made by wire transfer of immediately
available funds to the accounts specified by the Global Note Holder. With
respect to Physical Notes, the Company will make all payments of principal,
premium, if any, interest and Liquidated Damages, if any, at the office or

in the Borough of Manhattan, The City of New York an office or agency where
Notes may be presented or surrendered for payment, where Notes may be
surrendered for transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and of
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain such office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee. The
Company hereby designates the Corporate Trust Office as an initial Place of
Payment and as such office of the Company in the Borough of Manhattan, The City
of New York, and appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands so long as such Corporate Trust
Office remains a Place of Payment.

     Section 4.03. Money for Payments to Be Held in Trust. If the Company shall
at any time act as its own Paying Agent, it will, on or before each due date of
the principal of (and premium, if any) or interest and Liquidated Damages, if
any, on, any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest and Liquidated Damages, if any, so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, it will, prior to
each due date of the principal of (and premium, if any) or interest and
Liquidated Damages, if any, on, any Notes, deposit with a Paying Agent a sum
sufficient to pay the principal (and premium, if any) or interest and Liquidated
Damages, if any, so becoming due, such sum to be held in trust for the benefit
of the Persons entitled to such principal, premium or interest and Liquidated
Damages, and (unless such Paying Agent is the Trustee) the Company will promptly

Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 4.03, that such Paying Agent will:

     (a)  hold all sums held by it for the payment of principal of (and premium,
if any) or interest and Liquidated Damages, if any, on Notes in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

                                       49
<PAGE>

     (b)  give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any such payment of principal (and
premium, if any) or interest and Liquidated Damages, if any;

     (c)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d)  acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture and TIA relating to the duties, rights and
liabilities of such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest and Liquidated Damages, if any, on any Note and remaining unclaimed
for two years after such principal (and premium, if any) or interest and
Liquidated Damages, if any, has become due and payable shall be paid in the
appropriate proportion to the Company upon a Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease.

     Section 4.04.  SEC Reports. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes issued hereunder are outstanding,

<PAGE>

     (iii)  and the Company will not permit any of its Restricted Subsidiaries
that are not Subsidiary Guarantors to issue any shares of Preferred Stock
(including Acquired Preferred Stock);

provided, however, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired

recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
Letters of credit and bankers' acceptances shall be deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

     (b)  The foregoing provisions will not apply to:

     (i)  the incurrence by the Company of Indebtedness pursuant to the Existing

forth above or clauses (ii) or (iii) above or (xiii) or (xiv) below or this
clause (iv);

     (v)  the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Restricted
Subsidiaries; provided, however, that (i) if the Company or any Subsidiary
Guarantor is the obligor on such Indebtedness, such Indebtedness is expressly
subordinated to the prior payment in full in cash of all Obligations with

                                       52

any such Indebtedness being held by a Person other than the Company or a
Restricted Subsidiary and (B) any sale or other transfer of any such
Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary shall be deemed, in each case, to constitute an incurrence of such
Indebtedness by the Company or such Restricted Subsidiary, as the case may be;

     (vi)  the incurrence by the Company or any Restricted Subsidiary of Hedging
Obligations that are incurred for the purpose of (A) fixing or hedging interest

liability the payment of which is determined by reference to a foreign currency;
provided that the notional principal amount of any such Hedging Obligation does
not exceed the principal amount of the Indebtedness to which such Hedging
Obligation relates or (B) fixing or hedging risk with respect to fluctuations in
the cost of raw materials; provided that such obligation is entered into for
valid business purposes other than speculative purposes (as determined by the
Company's or such Restricted Subsidiary's principal financial officer in the
exercise of his or her good faith business judgment);

     (vii)    the issuance by any of the Company's Restricted Subsidiaries of
shares of Preferred Stock to the Company or a Wholly Owned Restricted
Subsidiary; provided that (A) any subsequent issuance or transfer of Equity
Interests that results in such Preferred Stock being held by a Person other than
the Company or a Wholly Owned Restricted Subsidiary or (B) the transfer or other
disposition by the Company or a Wholly Owned Restricted Subsidiary of any such
shares to a Person other than the Company or a Wholly Owned Restricted
Subsidiary shall be deemed, in each case, to constitute an issuance of such
Preferred Stock by such Subsidiary on such date that is not permitted by this
clause (vii);

     (viii) the incurrence by the Company or any of its Restricted Subsidiaries
of Indebtedness represented by tender, bid, performance, government contract,

     (x)  the issuance by any Finance Subsidiary of Preferred Stock with an
aggregate liquidation preference not exceeding the amount of Indebtedness of the
Company held by such Finance Subsidiary; provided that the Fixed Charge Coverage
Ratio for the Company's most recently ended four full fiscal quarters for which
financial statements have been filed with the SEC pursuant to the covenant
described below under Section 4.04 immediately preceding the date on which such
Preferred Stock is issued would have been at least 2.0 to 1, determined on a pro
forma basis (including a pro forma application of the net proceeds therefrom) as
if such Preferred Stock had been issued at the beginning of such four-quarter
period;

     (xi) the incurrence of Indebtedness by Foreign Subsidiaries in an aggregate
principal amount (or accreted value, as applicable) at any time outstanding and
incurred in reliance upon this clause (xi) not to exceed $100.0 million;

     (xii)  the Guarantee by any Restricted Subsidiary of Indebtedness of the
Company or a Restricted Subsidiary that was permitted to be incurred by another
provision of this covenant;

     (xiii)  Acquired Debt or Acquired Disqualified Stock; provided that such
Indebtedness or Disqualified Stock was not incurred in connection with or in
contemplation of such Person becoming a Restricted Subsidiary; and provided
further that immediately after giving effect to such incurrence, the Fixed
Charge Coverage Ratio for the Company's most recently ended four full fiscal
quarters for which financial statements have been filed with the SEC pursuant to
Section 4.04 immediately preceding the date of such incurrence would have been
at least 2.0 to 1, determined on a pro forma basis;

     (xiv)  Indebtedness or Disqualified Stock of a Specified Joint Venture or a
Subsidiary thereof existing at the time such Specified Joint Venture first
becomes a Restricted Subsidiary; provided that such Indebtedness or Disqualified
Stock was not incurred in connection with or in contemplation of such Specified
Joint Venture becoming a Restricted Subsidiary; and provided further that
immediately after giving effect to such Specified Joint Venture becoming a
Restricted Subsidiary, the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such Specified Joint Venture became a Restricted Subsidiary would have
been, determined on a pro forma basis, (x) at least 2.0 to 1 or (y) equal to or
greater than it was immediately prior to such Specified Joint Venture becoming a
Restricted Subsidiary;

     (xv)  with respect to any Specified Joint Venture that becomes a Restricted
Subsidiary, the incurrence by such Specified Joint Venture of Indebtedness under
any revolving credit facility in an aggregate principal amount at any time
outstanding not to exceed the aggregate principal amount of committed financing
under all revolving credit facilities of such Specified Joint Venture as in
effect on the Issue Date; and

                                       54
<PAGE>

     (xvi)  the incurrence by the Company or any Subsidiary Guarantor of
Indebtedness in an aggregate principal amount (or accreted value, as applicable)
at any time outstanding and incurred in reliance on this clause (xvi) not to

event that an item of Indebtedness or Preferred Stock meets the criteria of more
than one of the categories of permitted Indebtedness described in clauses (i)
through (xvi) above or is entitled to be incurred pursuant to Section 4.06(a),
the Company shall, in its sole discretion, classify such item of Indebtedness or
Preferred Stock in any matter that complies with this covenant and such
Indebtedness or Preferred Stock will be treated as having been incurred pursuant
to the clauses or Section 4.06(a), as the case may be, designated by the
Company.  The amount of Indebtedness issued at a price which is less than the
principal amount thereof shall be equal to the amount of the liability in
respect thereof determined in accordance with GAAP.

     Section 4.07.  Limitation on Restricted Payments. (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly:

Indebtedness owed to the Company or any Restricted Subsidiary), except, in each
case, payment of interest or principal at Stated Maturity; or

     (iv)  make any Restricted Investment (all such payments and other actions

<PAGE>

     (A)  no Default or Event of Default shall have occurred and be continuing
after giving effect thereto; and

offset any other dividend or distribution by such Joint Venture to such holder
and (y) such dividends or distributions do not exceed such holders' pro rata
share of the Joint Venture's cash flows from operating activities, minus any
non-cash charge to the extent that it represents an accrual of or reserve for
cash expenditures in any future period or amortization of a prepaid cash expense
in any future period.

     (c)  The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments Section
4.07(a) (except to the extent such Investments were repaid in cash, and, in the
case of a Joint Venture (and any Subsidiary of a Joint Venture) designated as an
Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company,
except to the extent that (1) such Investments were made after the Issue Date or
(2) in the case of a Specified Joint Venture, such Investments were made prior
to the Issue Date). All such outstanding Investments (except as provided in the
parenthetical included in the preceding sentence) will be deemed to constitute
Investments in an amount equal to the fair market value of such Investments at
the time of such designation (as conclusively determined by the Board of
Directors). Such designation will only be permitted if any such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. In the case of any
designation by the Company of a Person as an Unrestricted Subsidiary on the
first day that such Person is a Subsidiary of the Company in accordance with the
provisions of the Indenture, such designation shall be deemed to have occurred
for all purposes of the Indenture simultaneously with, and automatically upon,
such Person becoming a Subsidiary.

     (d)  Not later than the date of making any Restricted Payment, other than
those permitted by Sections 4.07(b)(ii)(x), 4.07(b)(vi), 4.07(b)(x) and
4.07(b)(xiv) above, and not later than the 120th day after making any Restricted
Payment permitted by Section 4.07(b)(vi) above, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

     Section 4.08.  Limitation on Dividend and other Payment Restrictions
affecting Restricted Subsidiaries and Joint Ventures.  (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
restriction on the ability of any Restricted Subsidiary to:

     (i)  (A) pay dividends or make any other distributions to the Company or
any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect
to

                                       61
<PAGE>

any other interest or participation in, or measured by, its profits or (B) pay
any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

        (ii)  make loans or advances to the Company or any of its Restricted
     Subsidiaries; or

        (iii) transfer any of its properties or assets to the Company or any
     of its Restricted Subsidiaries;

except for such restrictions existing under or by reason of:

     (a) existing agreements as in effect on the Issue Date;

     (b) Indebtedness permitted by the Indenture to be incurred containing
restrictions on the ability of Restricted Subsidiaries to consummate
transactions of the types described in clauses (i), (ii) or (iii) above not
materially more restrictive than those contained in the Indenture;

     (c) the Senior Secured Notes Indentures and the Senior Subordinated Notes
Indenture;

     (d) applicable law;

     (e) existing restrictions with respect to a Person acquired by the Company
or any of its Restricted Subsidiaries (except to the extent such restrictions
were put in place in connection with or in contemplation of such acquisition),
which restrictions are not applicable to any Person, or the properties or assets
of any Person, other than the Person, or the property or assets of the Person,
so acquired;

     (f) customary non-assignment provisions in leases and other agreements
entered into in the ordinary course of business;

     (g) construction loans and purchase money obligations (including Capital
Lease Obligations) for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (iii) above on the
property so constructed or acquired;

     (h) in the case of clause (iii) above, restrictions contained in security
agreements or mortgages securing Indebtedness of a Restricted Subsidiary to the
extent such restrictions restrict the transfer of the property subject to such
security agreements or mortgages;

     (i) a Permitted Refinancing, provided that the restrictions contained in
the agreements governing such Permitted Refinancing are not materially more
restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced (as conclusively evidenced by a Board
Resolution);

     (j) customary restrictions on a Finance Subsidiary imposed in such Finance
Subsidiary's organizational documents or by the terms of its Preferred Stock;

                                       62
<PAGE>

     (k) any restriction with respect to shares of Capital Stock of a Restricted
Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of such shares of Capital Stock or any restriction with respect to
the assets of a Restricted Subsidiary imposed pursuant to an agreement entered
into for the sale or disposition of such assets or all or substantially all the
Capital Stock of such Restricted Subsidiary pending the closing of such sale or
disposition;

     (l) in the case of any Restricted Subsidiary that is a Joint Venture,
customary restrictions on such Restricted Subsidiary contained in its joint
venture agreement, which restrictions are consistent with the past practice of
the Company and its Restricted Subsidiaries (as conclusively evidenced by a
Board Resolution);

     (m) existing restrictions with respect to a Specified Joint Venture or the
property or assets thereof or a Subsidiary of a Specified Joint Venture or the
property or assets thereof, in each case, at the time such Specified Joint
Venture first becomes a Restricted Subsidiary (except to the extent such
restrictions were put in place in connection with or in contemplation of such
Specified Joint Venture becoming a Restricted Subsidiary), which restrictions
are not applicable to any Person, or the properties or assets of any Person,
other than such Specified Joint Venture or the property or assets thereof or a
Subsidiary of such Specified Joint Venture or the property or assets thereof;
and

     (n) the Existing Credit Facility and related documentation as the same is
in effect on the Issue Date and as amended, modified, extended, renewed,
refunded, refinanced, restated or replaced from time to time; provided that the
Existing Credit Facility and related documentation as so amended, modified,
extended, reviewed, refunded, refinanced, restated or replaced is not materially
more restrictive, taken as a whole, as to the matters enumerated above than the
Existing Credit Facility and related documentation as in effect on the Issue
Date (as conclusively evidenced by a Board Resolution).

     For purposes of determining compliance with this covenant, in the event
that a restriction meets the criteria of more than one of the categories of
permitted restrictions described in clauses (a) through (n) above, the Company
shall, in its sole discretion, classify such restriction in any matter that
complies with this covenant and such restriction will be treated as existing
pursuant to the clauses designated by the Company.

     (b)  The Company will use best efforts (consistent with its contractual
obligations and fiduciary duties to any Joint Venture, in each case, as in
effect on the Issue Date) not to permit any of its Joint Ventures that are not
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any restriction on the ability of such Joint
Venture to:

        (i) (A) pay dividends or make any other distributions to the Company or
     any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with
     respect to any other interest or participation in, or measured by, its
     profits or (B) pay any Indebtedness owed to the Company or any of its
     Restricted Subsidiaries;

        (ii) make loans or advances to the Company or any of its Restricted
     Subsidiaries; or

                                       63
<PAGE>

        (iii) transfer any of its properties or assets to the Company or any of
     its Restricted Subsidiaries;

 except for such restrictions existing under or by reason of:

     (a) such Joint Venture's joint venture agreement or its credit facility
(provided that in each case such restrictions are consistent with the past
practice of the Company);

     (b) in the case of any Joint Venture existing on the Issue Date, its
existing agreements as in effect on the date of the Indenture and as amended,
modified, extended, restated or replaced from time to time; provided that no
such amendment, modification, extension, restatement or replacement results in
agreements that are materially more restrictive, taken as a whole, as to the
matters enumerated above than the existing agreements as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution);

     (c) in the case of LCR, any instrument governing its Indebtedness; and

     (d) the restrictions described in clauses (d), (e), (f), (g), (h), (j), (k)
and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k) to a
Restricted Subsidiary were references to a Joint Venture).

     Section 4.09. Limitation on Sales of Assets. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless:

        (i) the Company and/or the Restricted Subsidiary, as the case may be,
     receives consideration at the time of such Asset Sale at least equal to the
     fair market value (as conclusively evidenced by a Board Resolution set
     forth in an Officers' Certificate delivered to the Trustees) of the assets
     or Equity Interests issued or sold or otherwise disposed of; and

        (ii) at least 80% of the consideration therefor received by the Company
     and/or such Restricted Subsidiary is in the form of

          (A) cash or Cash Equivalents or

          (B) a controlling interest or a joint venture interest (to the extent
       otherwise permitted by the Indenture) in a business engaged in a
       Permitted Business or long-term property or assets that are used or
       useful in a Permitted Business;

provided that the amount of (x) any liabilities (as shown on the Company's or
such Restricted Subsidiary's most recent balance sheet) of the Company or any
Restricted Subsidiary (other than contingent liabilities and liabilities that
are by their terms subordinated to the Notes or any guarantee thereof) that are
assumed by the transferee of any such assets pursuant to a customary novation
agreement that releases the Company or such Restricted Subsidiary from further
liability and (y) any securities, notes or other obligations received by the
Company or any such Restricted Subsidiary from such transferee that are promptly
converted by the

                                       64
<PAGE>

Company or such Restricted Subsidiary into cash (to the extent of the cash
received), shall be deemed to be cash for purposes of this provision.

     (b)  Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

        (i) to permanently repay Senior Indebtedness (and to correspondingly
     reduce commitments with respect thereto in the case of revolving
     borrowings) of the Company or a Subsidiary Guarantor or Indebtedness (and
     to correspondingly reduce commitments with respect thereto in the case of
     revolving borrowings) of any Restricted Subsidiary that is not a Subsidiary
     Guarantor; provided that, so long as the provisions of Section 4.12 are in
     effect, only repayment of Senior Indebtedness incurred under the Existing
     Credit Facility (but not any refinancing thereof other than a credit
     facility with commercial banks and other lenders) or consisting of the 9.9%
     Debentures due 2000 of ARCO Chemical shall constitute a repayment of
     Indebtedness permitted pursuant to this clause (i); or

        (ii) to acquire a controlling interest or a joint venture interest (to
     the extent otherwise permitted by the Indentures) in another business or,
     the making of a capital expenditure or the acquisition of other long-term
     assets, in each case, in a Permitted Business (or enter into a binding
     commitment for any such expenditure or acquisition); provided that such
     binding commitment shall be treated as a permitted application of Net
     Proceeds from the date of such commitment until and only until the earlier
     of (x) the date on which such expenditure or acquisition is consummated and
     (y) the 180th day following the expiration of the aforementioned 360 day
     period. If the expenditure or acquisition contemplated by such binding
     commitment is not consummated on or before such 180th day and the Company
     shall not have applied such Net Proceeds pursuant to clause (i) above on or
     before such 180th day, such commitment shall be deemed not to have been a
     permitted application of Net Proceeds at any time;

provided that, so long as the provisions of Section 4.12 are in effect, the
Company may not apply Net Proceeds of a Significant Asset Sale pursuant to
clause (ii) above to satisfy its obligations to apply such proceeds pursuant to
this paragraph except to the extent that the provisions of the Existing Credit
Facility (but not any refinancing thereof other than a credit facility with
commercial banks and other lenders) require a mandatory prepayment from such
proceeds but the requisite lenders thereunder have waived such mandatory
prepayment.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce the revolving Indebtedness under the Existing Credit Facility
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the first sentence of this Section 4.09(b) will be
deemed to constitute "Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $25 million, the
Company will be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and, (x) if the
Company is required to do so under the terms of any other Indebtedness ranking
pari passu with such

                                       65
<PAGE>

Notes, such other Indebtedness, and (y) if the Company elects to do so, any
Existing ARCO Chemical Debt, on a pro rata basis with the Notes, that may be
purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase, in accordance
with the procedures set forth herein.

     To the extent that the aggregate amount of Notes (and any other pari passu
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offer is less than the Excess Proceeds, the Company may, subject to the
other terms of the Indenture, use any remaining Excess Proceeds for general
corporate purposes.

     If the aggregate principal amount of Notes surrendered by Holders thereof
in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased on a pro rata basis.

     Upon completion of the offer to purchase made under the Indenture, the
amount of Excess Proceeds shall be reset at zero.

     (d)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with any Asset
Sale Offer.

     Section 4.10.  Limitation on Affiliate Transactions.  (a)  The Company will
not, and will not permit any of its Restricted Subsidiaries to, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on an arms-length basis and (ii) the Company delivers
to the Trustee (a) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $10 million, a Board Resolution set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause  (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess
of $25 million, an opinion as to the fairness to the Company or such Restricted
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an investment banking firm of national standing; provided that:

     (i) transactions or payments pursuant to any employment arrangements or
employee, officer or director benefit plans or arrangements entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business;

     (ii) transactions between or among the Company and/or its Restricted
Subsidiaries;

     (iii) any Restricted Payment permitted by Section 4.07 of the type
described in clause (i) or (ii) of the first paragraph thereof;

                                       66
<PAGE>

     (iv) customary loans, advances, fees and compensation paid to, and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any of its Restricted Subsidiaries;

     (v) transactions entered into on an arms-length basis in the ordinary
course of business between the Company or any of its Restricted Subsidiaries and
any Joint Venture;

     (vi) sales (including a sale in exchange for a promissory note of or Equity
Interest in such Accounts Receivable Subsidiary) of accounts receivable and the
provision of billing, collection and other services in connection therewith, in
each case, to an Accounts Receivable Subsidiary in connection with any
Receivables Facility; and

     (vii) transactions pursuant to any contract or agreement in effect on the
date of the Indenture as the same may be amended, modified or replaced from time
to time so long as any such contract or agreement as so amended, modified or
replaced is, taken as a whole, no less favorable to the Company and its
Restricted Subsidiaries than the contract or agreement as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution); in each
case, shall not be deemed to be Affiliate Transactions and therefore not subject
to the requirements of clauses (i) and (ii) of the initial sentence above.

     Section 4.11.  Limitation on Liens.  (a) The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien (except Permitted Liens) on any asset
now owned or hereafter acquired, or any income or profits therefrom, unless all
payments due under the Indenture and the  Notes or the Subsidiary Guarantees are
secured on an equal and ratable basis with the obligations so secured (or, if
such obligations are subordinated by their terms to the  Notes or the
Subsidiary Guarantees, prior to the obligations so secured) until such time as
such obligations are no longer so secured.

     (b)  The Company and its Subsidiaries shall also comply with the provisions
of Section 4.12(a) until such provisions cease to be in effect pursuant to
Section 4.12(b).

     Section 4.12.  Equal and Ratable Liens.  (a) To the extent the Company or
any Subsidiary of the Company grants a Lien upon any of its property or assets
to secure the Existing Credit Facility Obligations, the Company or such
Subsidiary, as the case may be, shall, contemporaneously with the granting of
such Lien, secure the Indenture Obligations equally and ratably with the
Existing Credit Facility Obligations secured by such Lien.

     (b)  Notwithstanding the foregoing, from and after the date when all Liens
granted in favor of the holders of Existing Credit Facility Obligations are
released (and are not concurrently replaced with any new Liens on any asset of
the Company or any of its Restricted Subsidiaries securing Existing Credit
Facility Obligations), the provisions of this Section 4.12 will no longer apply.
The provisions of Section 4.11 will, however, continue to apply.

     Section 4.13.  No Amendment to Subordination Provisions.  The Company will
not amend, modify or alter the Senior Subordinated Notes Indenture in any way
that would (i) increase the principal of, advance the final maturity date of or
shorten the

                                       67
<PAGE>

Weighted Average Life to Maturity of any Senior Subordinated Notes such that the
final maturity date of the Senior Subordinated Notes is earlier than the 91st
day following the final maturity date of the Notes or (ii) amend the
subordination provisions of the Senior Subordinated Notes Indenture or any of
the defined terms used therein in a manner that would be adverse to the holders
of the Notes.

     Section 4.14. Repurchase of Notes upon a Change in Control. (a) Upon the
occurrence of a Change of Control, each Holder will have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to the offer described below
(the "Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control (the "Change of Control Payment Date"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's
request the Trustee will mail, a notice to each Holder offering to repurchase
the Notes held by such Holder pursuant to the procedures specified in such
notice.

     (b)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
applicable Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered, and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officer's
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company.

     The Paying Agent will promptly mail to each Holder of Notes so tendered the
Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such Note will be in a principal amount
of $1,000 or an integral multiple thereof.

     (d)  The Company 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 at
the same or a higher purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     Section 4.15.  Limitation on Sale and Leaseback Transactions.  The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any Sale and Leaseback Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Leaseback Transaction if: (a) the Company
or such Restricted

                                       68
<PAGE>

Subsidiary, as the case may be, could have (i) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such Sale and Leaseback
Transaction pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.06(a) (whether or not such covenant has ceased to be otherwise in
effect pursuant to Section 4.18) and (ii) incurred a Lien to secure such
Indebtedness pursuant to Section 4.11 without securing the Notes; and (b) the
gross cash proceeds of such Sale and Leaseback Transaction are at least equal to
the fair market value (as conclusively determined by the Board of Directors) of
the property that is the subject of such Sale and Leaseback Transaction.

     Section 4.16.  Limitation on Line of Business.  The Company will not, and
will not permit any of its Restricted Subsidiaries to, engage in any business
other than Permitted Businesses, except to such extent as would not be material
to the Company and its Subsidiaries taken as a whole.

     Section 4.17.  Limitation on Accounts Receivable Facilities.  The Company
may, and any of its Restricted Subsidiaries may, sell (including a sale in
exchange for a promissory note of or Equity Interest in such Accounts Receivable
Subsidiary) at any time and from time to time, accounts receivable to any
Accounts Receivable Subsidiary; provided that the aggregate consideration
received in each such sale is at least equal to the aggregate fair market value
of the receivables sold.

     Section 4.18.  Limited Applicability of Covenants when Notes are rated
Investment-Grade. Notwithstanding the foregoing, the Company's and its
Restricted Subsidiaries' obligations to comply with the provisions of Sections
4.06, 4.07, 4.08, 4.09, 4.10, 4.16, 4.17 and 4.22 will terminate and cease to
have any further effect from and after the first date when the Notes are rated
Investment Grade.

     Section 4.19.  Existence.  Subject to Articles 4 and 5 of this Indenture,
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with the respective organizational
documents of the Company and each such Subsidiary and the rights (whether
pursuant to charter, partnership certificate, agreement, statute or otherwise),
material licenses and franchises of the Company and each such Subsidiary;
provided that the Company shall not be required by this Section 4.19 to preserve
any such right, license or franchise, or the existence of any Restricted
Subsidiary, if the Company shall determine that the maintenance or preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries taken as a whole.

     Section 4.20.  Payment of Taxes and Other Claims.  The Company will pay or
discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (a) all material taxes, assessments and governmental charges levied
or imposed upon (i) the Company or any such Subsidiary, (ii the income or
profits of any such Subsidiary which is a corporation or (ii the property of the
Company or any such Subsidiary and (b) all material lawful claims for labor
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good

                                       69
<PAGE>

faith by appropriate proceedings and for which adequate reserves have been
established in accordance with GAAP.

     Section 4.21.  Maintenance of Properties and Insurance.  The Company will
cause all material assets necessary in the conduct of its business or the
business of any of its Restricted Subsidiaries, to be maintained and kept in
good condition, repair and working order (ordinary wear and tear excepted) and
will cause to be made all necessary repairs, renewals and replacements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided that nothing in this Section 4.21 shall prevent the Company or any such
Subsidiary from discontinuing the use, operation or maintenance of any of such
assets or disposing or abandoning of any of them, if such discontinuance,
disposal or abandonment is, in the judgment of the Company, desirable in the
conduct of the business of the Company or such Subsidiary.

     The Company will maintain, and will cause each of its Restricted
Subsidiaries to maintain (either in the Company's name or in such Subsidiary's
own name) insurance on all their respective properties consistent with the
insurance maintained on the Issue Date or otherwise in at least such amounts
(with no materially greater risk retention) and against at least such risks as
are usually maintained, retained or insured against in the same general area by
companies of established repute owning similar properties in such area and
engaged in the same or a similar business, in either case, to the extent
available to the Company and its Restricted Subsidiaries on commercially
reasonable terms.

     Section 4.22.  Limitation on Issuance of Guarantees by Restricted
Subsidiaries. (a) The Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee or secure the
payment of any other Indebtedness of  the Company or any of its Restricted
Subsidiaries (except Indebtedness of such Restricted Subsidiary or a Restricted
Subsidiary of such Restricted Subsidiary) unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture in the form of
Exhibit B hereto providing for the Guarantee of the payment of the Notes by such
Restricted Subsidiary and shall deliver an Opinion of Counsel to the Trustee
pursuant to paragraph (c) below; provided that this paragraph shall not be
applicable to (x) any Guarantee of any Restricted Subsidiary that existed at the
time such Person became a Restricted Subsidiary and was not incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary, (y) Guarantees of Indebtedness of a Restricted Subsidiary that is a
Foreign Subsidiary by a Restricted Subsidiary that is a Foreign Subsidiary or
(z) the granting of Liens by a Joint Venture Subsidiary to secure Indebtedness
under the Existing Credit Facility and the Senior Secured Notes. If the Notes
are (A) pari passu with the Guaranteed Indebtedness, then the Subsidiary
Guarantee shall be pari passu with, or senior to, the guarantee of such
Guaranteed Indebtedness or (B) senior to the Guaranteed Indebtedness, then the
Subsidiary Guarantee shall be senior to the guarantee of such Guaranteed
Indebtedness at least to the extent that the Notes are senior to such Guaranteed
Indebtedness.

     (b)  Notwithstanding the foregoing, each Subsidiary Guarantee by a
Restricted Subsidiary shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all the Company's and each Restricted Subsidiary's
Capital Stock in such Restricted Subsidiary

provided in Section 5.03(b), (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee (or, in the case of
the Subsidiary Guarantees of Lyondell Chemical Worldwide, Inc. and Lyondell
Chemical Nederland, Ltd. issued on the Issue Date, the release or discharge of
its Guarantee of Indebtedness under the Existing Credit Facility), except a
discharge or release by or as a result of payment under such Guarantee, and
(iii) the designation of such Restricted Subsidiary as an Unrestricted
Subsidiary in accordance with the terms of the Indenture.

     (c) The Opinion of Counsel described above shall be to the effect that such
supplemental indenture has been duly authorized, executed and delivered by such
Subsidiary and constitutes a valid and binding obligation of such Subsidiary,
enforceable against such Subsidiary in accordance with its terms (subject to
customary exceptions).

     Section 4.23.  Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes that consent, waive or agree to amend such term or provision in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

     at the beginning of the applicable four-quarter period, be permitted to
     incur at least $1.00 of additional Indebtedness pursuant to the Fixed
     Charge Coverage Ratio test set forth in Section 4.06(a). The foregoing

     merger or consolidation, no consideration (other than common stock in the
     surviving Person or the Company) shall be issued or distributed to the

     (b)  The Company will not lease all or substantially all its assets to
another Person.

merged or to which such sale, assignment, transfer, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition, the provisions of this Indenture referring to
the "Company" shall refer instead to the successor corporation), and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein,
and the predecessor Company shall be released from all its obligations hereunder
and under the Notes.

     (b)  The sale, assignment, transfer, lease, conveyance or other disposition
by the Company of all or substantially all its property or assets taken as a
whole to one or more of the Company's Subsidiaries shall not relieve the Company
from its obligations under the Indenture and the Notes.

     formed by or surviving any such consolidation or merger (if other than the
     Company or such Subsidiary Guarantor) assumes all the obligations of such
     Subsidiary Guarantor, pursuant to a supplemental indenture in form and
     substance reasonably satisfactory to the Trustee, under the Notes;

                                       72
<PAGE>

        (ii) immediately after giving effect to such transaction, no Default or
     Event of Default exists; and

        (iii) the Company would, at the time of such transaction and after
     giving pro forma effect thereto as if such transaction had occurred at the
     beginning of the applicable four-quarter period, (A) have a Consolidated
     Net Worth immediately after the transaction equal to or greater than the
     Consolidated Net Worth of the Company immediately preceding the transaction
     and (B) except with respect to a consolidation or merger with a Person that

     All the Subsidiary Guarantees issued pursuant to clause (i) above shall in
all respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all such Subsidiary Guarantees had been issued

consolidation or otherwise, of all the Capital Stock of any Subsidiary Guarantor
to any Person that is not an Affiliate of the Company permitted by the
applicable provisions of the Indenture, such Subsidiary Guarantor will be
released and relieved of any obligations under its Subsidiary Guarantee;
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of the Indenture.

     Section 5.04.  Opinion of Counsel to Trustee.  The Trustee, subject to the

of 25% or more in aggregate principal amount of the Notes;

     (e)  any default occurs under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Significant
Subsidiaries (or any Indebtedness for money borrowed Guaranteed by the Company
or any of its Significant Subsidiaries if the Company or a Significant
Subsidiary does not perform its payment obligations under such Guarantee within
any grace period provided for in the documentation governing such Guarantee)
and, whether such Indebtedness or Guarantee exists on the date of the indenture
or is thereafter created, which default (a) constitutes a Payment Default or (b)
results in the acceleration of such Indebtedness prior to its Stated Maturity,
and in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a
Payment Default or that has been so accelerated, aggregates $50 million or more;

     (f)  failure by the Company or any of its Significant Subsidiaries to pay a
final judgment or final judgments aggregating in excess of $50 million, which
judgment or judgments are not paid, discharged or stayed for a period of 60

     (g)  a court having jurisdiction in the premises enters a decree or order

involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, (ii) appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Company or
any Significant Subsidiary or for all or substantially all the property and

                                       74
<PAGE>

     (i)  except as permitted by the Indenture, any Subsidiary Guarantee issued
hereunder shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall deny or disaffirm its obligations under the Subsidiary
Guarantees issued thereunder; or

writing that it has any further liability under any Security Document or gives
written notice to such effect (in each case other than in accordance with the
terms of this Indenture (including Section 14.01(b)) or the terms of the
Existing Credit Facility or the Security Documents (including the cessation of
effectiveness of any Security Document in connection with a release of all
collateral covered thereby in accordance with the terms of this Indenture, the
Existing Credit Facility and such Security Document) or unless waived by the
requisite lenders under the Existing Credit Facility if, after the waiver, the
Company is in compliance with Section 4.12; provided that if a failure of the
sort described in this clause (j) is susceptible of cure, no Event of Default
shall arise under this clause (j) with respect thereto until 30 days after
notice of such failure shall have been given to the Company by the Trustee or
Holders of at least 25% in principal amount of the then outstanding Notes issued
under the Indenture.

     Section 6.02.  Acceleration.   If an Event of Default (other than an Event
of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Subsidiary Guarantor) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then Outstanding, by written notice to the Company
(and to the Trustee if such notice is given by the Holders (the "Acceleration
Notice")), may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued but unpaid interest and
Liquidated Damages, if any, on all the Notes to be due and payable.  Upon a
declaration of acceleration, such principal, premium, if any, and accrued
interest and Liquidated Damages, if any, shall be immediately due and payable.
If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs
with respect to the Company or any Subsidiary Guarantor, the principal of,
premium, if any, accrued interest and Liquidated Damages, if any, on the Notes
then Outstanding shall ipso facto become and be immediately due and payable

     Section 6.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest and Liquidated Damages on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  All remedies are cumulative
to the extent permitted by law.

                                       75
<PAGE>

     Section 6.04.  Waiver of Past Defaults.  The Holders of at least a majority
in principal amount of the outstanding Notes, by written notice to the Company
and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences under the Notes, if (i) all
existing Events of Default, other than the nonpayment of the principal of and
premium, if any, and interest and Liquidated Damages, if any, on such Notes that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     Section 6.05.  Control by Majority.  The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from the
Holders.

     Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with
respect to this Indenture or the Notes unless:

     (a)  the Holder gives the Trustee written notice of a continuing Event of
Default;

     (b)  the Holders of at least 25% in aggregate principal amount of
Outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c)  such Holder or Holders offer the Trustee security or indemnity
satisfactory to it against any loss, liability or expense;

     (d)  the Trustee does not comply with the request within 60 days after
receipt thereof and the offer of security or indemnity; and

     (e)  during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes do not give the Trustee a
direction inconsistent with the request.

     Section 6.07.  Rights of Holders to Receive Payment.  Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, interest and Liquidated Damages, if any, on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

                                       76
<PAGE>

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest and Liquidated Damages, if any,
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and Liquidated Damages, if any, and such further amount
as shall be sufficient to cover amounts due the Trustee under Section 7.08,
including the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     Section 6.09.  Trustee May File Proofs of Claim.  The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section  7.08.  To the
extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section  7.08 out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties which the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

     Section 6.10.  Priorities.  If the Trustee collects any money pursuant to
this Article or receives any money from the Collateral Agent as the distribution
of proceeds received upon realization of any Collateral, it shall pay out the
money in the following order:

     First:  to the Trustee, its agents and attorneys for amounts due under
Section  7.08, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

     Second:  to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, interest and Liquidated Damages, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Notes for principal, premium, if any, interest and Liquidated Damages,
respectively; and

                                       77
<PAGE>

     Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section  6.10 upon five Business Days prior notice to
the Company.

     Section 6.11.  Undertaking for Costs.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section  6.06, or a suit by
Holders of more than 10% in aggregate principal amount of the then Outstanding
Notes.

     Section 6.12.  Restoration of Rights and Remedies.  If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture or any Note and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case the Company, any other obligor upon the Notes, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

     Section 6.13.  Rights and Remedies Cumulative.  No right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 6.14.  Waiver of Stay, Extension or Usury Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time hereafter in force, that would prohibit
or forgive the Company from paying all or any portion of the principal of (or
premium, if any), interest or Liquidated Damages, if any, on the Notes
contemplated herein or in the Notes or that may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenant that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  The Trustee

     Section 7.01.  Certain Duties and Responsibilities.  (a)  Except during the
continuance of an Event of Default,

        (i) the Trustee need perform only those duties that are specifically set
     forth in this Indenture and no others, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

        (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     in the case of any such certificates or opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of mathematical calculations or other
     facts stated therein).

     (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

     (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph does not
limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts; and
(iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it
pursuant to Section 6.06.

     (d)  The Trustee may refuse to perform any duty or exercise any right or
power or expend or risk its own funds or otherwise incur any financial liability
unless it receives indemnity satisfactory to it against any loss, liability or
expense.

     (e)  Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of Sections 7.01
and 7.03.

     Section 7.02.  Notice of Defaults.  (a) Within 90 days after the occurrence
of any Default, the Trustee shall transmit by mail to all Holders, as their
names and addresses appear in the Register, notice of such Default hereunder
actually known to the Trustee unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium (if any) or interest and Liquidated Damages, if
any, on, any Note, the Trustee may withhold such notice if and so long as the

notice is not opposed to the interests of the Holders.

     (b) The Trustee shall not be required to take notice or be deemed to have
notice or knowledge of any event or of any Default (except default in the
payment of monies to the Trustee which are required to be paid to the Trustee on
or before a specified date or within a specified time after receipt by the
Trustee of a notice or a certificate which was in fact received), unless the
Trustee shall receive from the Company or a Holder a notice stating that the
same has occurred and is continuing, and specifying the same, and in the absence
of such notice the Trustee may conclusively assume that the same does not exist,
except as aforesaid.

     Section 7.03.  Certain Rights of Trustees.   Subject to the provisions of
Section 7.01:

        (i) the Trustee may conclusively rely and shall be protected in acting

     bond, note, other evidence of indebtedness or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties;

        (ii) any request or direction of the Company mentioned herein shall be

        (iii) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,

     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon the Officer's Certificates of the Company;

        (iv) the Trustee may consult with counsel of its selection and the
     written advice of such counsel or any Opinion of Counsel shall be full and
     complete authorization and protection in respect of any action taken,

        (v) in case an Event of Default occurs and is continuing, the Trustee
     shall be under no obligation to exercise any of the rights or powers vested
     in it by this Indenture at the request or direction of any of the Holders
     pursuant to this Indenture, unless such Holders shall have offered to the
     Trustee security or indemnity satisfactory to it against any loss,
     liability or expense which might be incurred by it in compliance with such
     request or direction;

        (vi) the Trustee shall not be bound to make any investigation into the

     bond, note, other evidence of indebtedness or other paper or document;

                                       80
<PAGE>

        (vii) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and

        (viii) the rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and to each agent, custodian and other
     Person employed to act hereunder.

     Section 7.04.  Not Responsible for Recitals or Issuance of Notes.   The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder and that the
statements made by it in a Statement of Eligibility and Qualification on Form T-
1 supplied to the Company in connection with the registration of any Notes
issued hereunder will be true and accurate subject to the qualifications set
forth therein. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of the Notes or the
proceeds thereof.

     Section 7.05. Trustee's Disclaimer. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company' use of the proceeds from the Notes, it shall not be
responsible for any statement in the offering memorandum for the Notes or in the
Indenture or the Notes (other than its certificate of authentication), the acts
of a prior Trustee hereunder, or the determination as to which beneficial owners
are entitled to receive any notices hereunder.

     Section 7.06. May Hold Notes. The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Notes and, subject to
Section 7.09 and Section 7.14, may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

     Section 7.07. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.

     Section 7.08.  Compensation and Reimbursement. The Company agrees:

     (a) to pay to the Trustee from time to time such compensation as the
Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

                                       81
<PAGE>

     (b)  to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses, advances and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad
faith; and

     (c)  to indemnify the Trustee and any predecessor Trustee for, and to hold
it harmless against, any loss, damage, claims, liability or expense (including
taxes, other than taxes based on the income of the Trustee) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this trust, including the reasonable costs and
expenses of defending itself against any claim (whether asserted by the Company,
a Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

     The Company' payment obligations pursuant to this Section 7.08 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(g) or 6.01(h), the
expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the TIA, within 90 days the Trustee
shall either eliminate such conflicting interest, apply to the SEC for
permission to continue as Trustee with such conflicting interest, or resign, to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. To the extent permitted by such Act, the Trustee shall
not be deemed to have a conflicting interest by virtue of being a trustee under
this Indenture with respect to Original Notes and Additional Notes, or a trustee
under any other indenture between the Company and the Trustee.

     Section 7.10. Corporate Trustee Required; Eligibility. (a) There shall at
all times be one (and only one) Trustee hereunder. The Trustee shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $100,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 7.10
and to the extent permitted by the TIA, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
7.10, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

     Section 7.11.  Resignation and Removal; Appointment of Successor.  (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 7.12.

     (b)  The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 7.12 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                                       82
<PAGE>

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 7.12 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the Trustee being removed may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If at any time:

        (i) the Trustee shall fail to comply with Section 7.09 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder for at least six months, or

        (ii) the Trustee shall cease to be eligible under Section 7.10 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

        (iii) the Trustee shall become incapable of acting or shall be adjudged
     bankrupt or insolvent or a receiver of the Trustee or of its property shall
     be appointed or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B) subject
to Section 6.11, any Holder who has been a bona fide Holder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee or Trustees.

     (d)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor Trustee and shall comply with the applicable
requirements of Section 7.12. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 7.12,
become the successor Trustee and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner required by
Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide
Holder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     (e)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.10. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

                                       83

     Section 7.12.  Acceptance of Appointment by Successor.  (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

     (b)  Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to above.

     (c)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

     Section 7.13. Merger, Conversion, Consolidation or Succession to Business.
(a) Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

     Section 7.14. Preferential Collection of Claims Against the Company.  (a)
If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Notes), the Trustee shall be subject to the provisions of
the TIA regarding the collection of claims against the Company (or any such
other obligor).

     Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Company to authenticate the Notes. Any
such appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer, a copy of which instrument shall be promptly furnished to
the Company. Unless limited by the terms of such appointment, an Authenticating
Agent may authenticate Notes whenever the Trustee may do so. Each reference in
this Indenture to authentication (or execution of a certificate of
authentication) by the Trustee includes authentication (or execution of a
certificate of authentication) by such Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

accuracy of such list. The Trustee may destroy any list furnished to it as
provided in Section 8.01 upon receipt of a new list so furnished.

<PAGE>

     (c) It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

     (d)  After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by the
Company and that such amendment, supplement or waiver is a valid and binding
agreement of the Company, enforceable against it in accordance with its terms
(subject to customary exceptions).

     Section 9.04. Revocation and Effect of Consents. (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of that Note or any
Note that evidences all or any part of the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. Subject to the
following paragraph of this Section 9.04, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note by notice to the Trustee or the
Company received by the Trustee or the Company, as the case may be, before the
date on which the Trustee receives an Officer's Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver as set forth in Section 1.08.

     (b) After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (i)
through (viii) of Section 9.02(b). In that case, the amendment, supplement or
waiver shall bind each Holder of a Note who has consented to it and every
subsequent Holder of such Note or any Note that evidences all or any part of the
same debt as the consenting Holder's Note.

     Section 9.05. Conformity with TIA.  (a) Every amendment or supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the TIA as then in effect.

     Section 9.06. Notation on or Exchange of Notes.  (a)  If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Company and in accordance with the specific direction of the Company)
request the

                                       88
<PAGE>

Holder to deliver its Note to the Trustee. The Trustee shall (if required by the
Company and in accordance with the specific written direction of the Company)
place an appropriate notation on the Note about the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
amendment, supplement or waiver.

Trustee of such Redemption Date and of the principal amount of Notes to be
redeemed.

     Section 10.04. Selection by Trustee of Notes to Be Redeemed. In the case of
any partial redemption, selection of the Notes for redemption will be made not
more than 60 days prior to the Redemption Date by the Trustee in compliance with
the requirements of the principal national securities exchange, if any, on which
the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the applicable Trustee shall deem fair and appropriate;
provided that no Notes of $1,000 or less shall be redeemed in part.

     (a) The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the portion of the principal amount thereof to be redeemed. On and
after the Redemption Date, interest and Liquidated Damages will cease to accrue
on Notes or portions thereof called for redemption.

     (b) For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Notes shall relate, in
the case of any Note redeemed or to be redeemed only in part, to the portion of
the principal of such Note that has been or is to be redeemed.

     Section 10.05. Notice of Redemption. (a) Notice of redemption or purchase
as provided in Section 10.01 shall be deemed to have been given upon the mailing

         (iii)   if less than all Outstanding Notes are to be redeemed, the
     identification (and, in the case of partial redemption, the respective
     principal amounts) of the particular Notes to be redeemed,

         (iv)    that on the Redemption Date the Redemption Price will become
     due and payable upon each such Note to be redeemed, and that, unless the
     Company default in making such redemption payment or any Paying Agent is
     prohibited from making such payment pursuant to the terms of this
     Indenture, interest and Liquidated Damages thereon shall cease to accrue
     from and after said date,

         (v)     the place or places where such Notes are to be surrendered for
     payment of the Redemption Price and the name and address of the Paying
     Agent or Paying Agents,

and at the expense of the Company; provided that such notice to the Trustee may
be revoked by the Company by written notice delivered to the Trustee prior to
the date proposed for the mailing of the notice of such redemption to the
Holders.

     (c) The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note.

     Section 10.06. Deposit of Redemption Price. (a) On or prior to 10:00 a.m.,
New York City time on any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, the Company

                                       90
<PAGE>

shall segregate and hold in trust as provided in Section 4.03) an amount of
money sufficient to pay the Redemption Price of, and any accrued and unpaid
interest and Liquidated Damages, if any, on, all the Notes or portions thereof
which are to be redeemed on that date.

     Section 10.07. Notes Payable on Redemption Date. (a) Notice of redemption
having been given as provided in this Article 10, the Notes so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
herein specified and from and after such date (unless Company shall default in
the payment of the Redemption Price or any Paying Agent is prohibited from
paying the Redemption Price pursuant to the terms of this Indenture) such Notes
shall cease to bear interest and Liquidated Damages. Upon surrender of such
Notes for redemption in accordance with such notice, such Notes shall be paid by
the Company at the Redemption Price. Installments of interest and Liquidated
Damages, if any, whose Interest Payment Date is on or prior to the Redemption
Date shall be payable to the Holders of such Notes registered as such on the
relevant Regular Record Dates according to their terms and the provisions of
Section 3.07.

     (b) On and after any Redemption Date, if money sufficient to pay the
Redemption Price of and any accrued and unpaid interest and Liquidated Damages
on Notes called for redemption shall have been made available in accordance with
Section 10.06, the Notes (or the portions thereof) called for redemption will
cease to accrue interest and Liquidated Damages and the only right of the
Holders of such Notes (or portions thereof) will be to receive payment of the
Redemption Price of, and subject to the last sentence of Section 10.07(a), any
accrued and unpaid interest and Liquidated Damages, if any, on such Notes (or
portions thereof) to the Redemption Date. If any Note (or portion thereof)
called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest
and Liquidated Damages from the Redemption Date at the rate borne by the Note
(or portion thereof).

     Section 10.08. Notes Redeemed in Part. Any Note that is to be redeemed only
in part shall be surrendered at a Place of Payment (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Note without service charge, a new Note or Notes, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Note so
surrendered.

of and at the expense of the

         than (y) Notes that have been destroyed, lost or stolen and that have
         been replaced or paid as provided in Section 3.06, and (z) Notes for
         whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Company and thereafter repaid to
         the Company or discharged from such trust, as provided in Section 4.03)

                 arrangements reasonably satisfactory to the Trustee for the
                 giving of notice of redemption by the Trustee in the name, and
                 at the expense, of the Company,

         (ii)    the Company has irrevocably deposited or caused to be deposited
     with the Trustee an amount in United States dollars, U.S. Government

     Notes that have become due and payable), or to the Stated Maturity or
     Redemption Date, as the case may be;

         (iii)   the Company has paid or caused to be paid all other sums then

     provided that any such counsel may rely on any Officer's Certificate as to
     matters of fact (including as to compliance with the foregoing clauses (i),
     (ii) and (iii)).

     (b) Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.08 and, if money shall
have been deposited with the Trustee pursuant to clause (ii) of Section
11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

     Section 11.02. Application of Trust Money. Subject to the provisions of the
last paragraph of Section 4.03, all money deposited with the Trustee pursuant to
Section 11.01 shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal
(and premium, if any) and interest and Liquidated Damages on the Notes; but such
money need not be segregated from other funds except to the extent required by
law.

                      Defeasance and Covenant Defeasance

     Section 12.01. Option of the Company to Effect Defeasance or Covenant
Defeasance. The Company may at its option by a Board Resolution, at any time,
elect to have either Section 12.02 or Section 12.03 applied to the Outstanding
Notes upon compliance with the conditions set forth below in this Article 12.

     Section 12.02. Legal Defeasance and Discharge.  Upon the exercise by the
Company under Section 12.01 of the option applicable to this Section 12.02, the
Company shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this
Section 12.02, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages on such Notes when such payments are
due, (ii) the obligations of the Company with respect to such Notes under
Sections 1.06, 2.03, 3.03, 3.04, 3.05, 3.06, 3.13, 3.14, 4.01, 4.02, 4.03 and
12.05 hereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Company in connection therewith
and with this Article 12.  Subject to compliance with this Article 12, the
Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 hereof with respect to the
Notes.

     Section 12.03. Covenant Defeasance.  Upon the exercise by the Company under
Section 12.01 of the option applicable to this Section 12.03, the Company shall
be released from its obligations under the covenants contained in Sections 4.06
through

                                       93
<PAGE>

Section 4.18, Section 4.22, Article 14 and clause (iv) of Section 5.01(a) hereof
with respect to the Outstanding Notes and no Default under Section 6.01(e), (f)
and (j) shall thereafter constitute a Default or Event of Default on the date
which is the 123rd day after the deposit referred to in Section 12.04(a);
provided that all of the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"), and the Notes shall thereafter be deemed not Outstanding
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants,
but shall continue to be deemed Outstanding for all other purposes hereunder.
For this purpose, such Covenant Defeasance means that, with respect to the
Outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section
6.01(c) or (d), but, except as specified above, the remainder of this Indenture
and such Notes shall be unaffected thereby.

     Section 12.04. Conditions to Legal or Covenant Defeasance. The following
shall be the conditions to application of either Section 12.02 or Section 12.03
to the Outstanding Notes:

     (a) the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay (i) the principal of, premium, if any, and accrued interest and
Liquidated Damages, if any, on the Notes when such payments are due in
accordance with the terms of this Indenture and the Notes or (ii) in the case of
Legal Defeasance, accrued interest and Liquidated Damages, if any, on the Notes
through a scheduled redemption date and the principal of, and premium on the
Notes on such redemption date; provided that, at the time of deposit, the
Company irrevocably authorize the Trustee to issue a timely notice of redemption
and to take such other steps reasonably requested by the Trustee to ensure that
such redemption will be effectuated;

     (b) in the case of an election under Section 12.02, the Company has
delivered to the Trustee (i) either (x) 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 the exercise by the Company of its option under this Article 12
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of this Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that, as a result of the creation of
the defeasance trust, the Company will not be required to register under the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund will not be subject to the effect of Section

                                       94
<PAGE>

547 of the United States Bankruptcy Code or Section 15 of the New York Debtor
and Creditor Law or any comparable provision of applicable law;

     (c) in the case of an election under Section 12.03, the delivery by the
Company to the Trustee of (i) an Opinion of Counsel to the effect that, among
other things, the 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 amount 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 (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, the Company will not be required to
register under the Investment Company Act of 1940 and after the passage of 123
days following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or any comparable provision of applicable law;

     (d) immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound;

     (e) if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to the
effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge;

     (f) the Company shall have delivered to the Trustee Officer's Certificates
stating that the deposit made by the Company pursuant to its election under
Sections 12.02 or 12.03 was not made by the Company with the intent of
preferring the Holders over the other creditors of the Company with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others; and

     (g) the Company shall have delivered to the Trustee Officer's Certificates
and an Opinion of Counsel, each stating that all conditions precedent provided
for relating to either the Legal Defeasance under Section 12.02 or the Covenant
Defeasance under Section 12.03 (as the case may be) have been complied with as
contemplated by this Section 12.04.

     Section 12.05. Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions.  Subject to Section  12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section  12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

                                       95
<PAGE>

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section  12.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

     Anything in this Article 12 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or U.S. Government Obligations held by it as provided in
Section  12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
12.04(a) hereof), are in excess of the amount thereof which would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

     Section 12.06. Repayment to Company. Any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest and Liquidated Damages on any
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest and Liquidated Damages has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause
to be published once, in The New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 12.07. Reinstatement. If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section 12.02
or 12.03, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 12.02 or 12.03 until such time as the Trustee or Paying Agent is
permitted to apply all such amounts in accordance with Section 12.02 or 12.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest and Liquidated Damages on
any Note following the reinstatement of its Obligations, the Company shall be
subrogated to the rights of the Holder of such Note to receive such payment from
the amounts held by the Trustee or Paying Agent.

                             Subsidiary Guarantees

     Section 13.01. The Guarantees. (a) Subject to the provisions of this
Article 13, each Subsidiary Guarantor hereby irrevocably and unconditionally
guarantees, jointly and severally, the full and punctual payment (whether at
Stated Maturity, upon acceleration, optional redemption, upon repurchase
following a Change of Control Offer or an Asset Sale Offer or otherwise) of the
principal of and premium, if any, and interest and Liquidated Damages, if any,
on, and all other amounts payable under, each Note provided for under this
Indenture, and the full and punctual payment of all other amounts payable by the
Company under this Indenture. Upon failure by the Company to pay punctually any
such amount, each Subsidiary Guarantor shall forthwith on demand pay the amount
not so paid at the place and in the manner specified in this Indenture.

     Section 13.02. Guarantee Unconditional. The obligations of the Subsidiary
Guarantors hereunder shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall, to the fullest extent permitted by law,
not be released, discharged or otherwise affected by:

     (a) any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Company under this Indenture or any Note, by
operation of law or otherwise;

     (b) any modification or amendment of or supplement to this Indenture or
any Note; provided that any such modification which increases the obligations of
each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary
Guarantor without its consent;

     (c) any release, impairment, non-perfection or invalidity of any direct or
indirect security for any obligation of the Company or any Subsidiary Guarantor
hereunder;

     (d) any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Company or its assets or any resulting release or
discharge of any obligation of the Company contained in this Indenture or any
Note;

     (e) the existence of any claim, set-off or other rights which the
Subsidiary Guarantors may have at any time against the Company, the Trustee or
any other Person, whether in connection with this Indenture or any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

     (f) any invalidity or unenforceability relating to or against the Company
for any reason of this Indenture or any Note, or any provision of applicable law
or regulation purporting to prohibit the payment by the Company of the principal
of or interest and Liquidated Damages on any Note or any other amount payable by
the Company under this Indenture; or

                                       97
<PAGE>

     (g) any other act or omission to act or delay of any kind by the Company,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Subsidiary Guarantor's obligations hereunder.

     Section 13.03. Discharge; Reinstatement.  The Subsidiary Guarantors'
obligations hereunder shall remain in full force and effect until the principal
of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
and all other amounts payable by the Company under this Indenture shall have
been paid in full.  If at any time any payment of the principal of, premium, if
any, or interest and Liquidated Damages, if any, on any Note or any other amount
payable by the Company under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, the Subsidiary Guarantors' obligations hereunder with
respect to such payment shall be reinstated as though such payment had been due
but not made at such time.

     Section 13.04. Waiver by the Subsidiary Guarantors. The Subsidiary
Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and
any notice not provided for herein, as well as any requirement that at any time
any action be taken by any Person against the Company or any other Person.

     Section 13.05. Subrogation and Contribution. Upon making any payment with
respect to any obligation of the Company under this Article 13, the Subsidiary
Guarantor making such payment shall be subrogated to the rights of the payee
against the Company with respect to such obligation; provided that such
Subsidiary Guarantor shall not enforce either (i) any right to receive payment
by way of subrogation against the Company or against any direct or indirect
security for such obligation, or any other right to be reimbursed, indemnified
or exonerated by or for the account of the Company in respect thereof or (ii)
any right to receive payment, in the nature of contribution or for any other
reason, from any other Subsidiary Guarantor with respect to such payment, in
each case so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

     Section 13.06. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Company under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of this Indenture
shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on
demand by the Trustee or the Holders.

     Section 13.07. Limits of Guarantees. Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law. To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the maximum
amount that would not render such Subsidiary Guarantor's obligations subject

                                       98
<PAGE>

to avoidance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law.

     Section 13.08. Execution and Delivery of Note Guarantee.  To evidence its
Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
hereby agrees that this Indenture (or a supplemental indenture in the form of
Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by
one of its Officers.

     The signature of an Officer of a Subsidiary Guarantor on the Indenture
shall bind such Subsidiary Guarantor, notwithstanding that such individual has
ceased to hold such office prior to the authentication and delivery of any Note
or did not hold such office at the date of such Note.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Indenture on behalf of the Subsidiary Guarantors.

                                  ARTICLE 14

                             Security Arrangements

     Section 14.01. Security. (a) In order to secure the Indenture Obligations
equally and ratably with the Existing Credit Facility Obligations and, with
respect to certain of the Collateral, the Existing ARCO Chemical Debt, the
Company will, and will cause each of its Restricted Subsidiaries named in any
Existing Security Document as a party thereto, to execute and deliver to the
Collateral Agent prior to the Issue Date each Existing Security Document to
which it is a party. The Company and its Restricted Subsidiaries shall comply
with all covenants and agreements contained in the Security Documents the
failure to comply with which would have a material and adverse effect on the
Liens purported to be created thereby, unless such failure to comply is waived
by the requisite lenders under the Existing Credit Facility if, after that
waiver, the Company is in compliance with Section 4.12.

     (b) The Trustee and each holder of each Note by its acceptance of that
Note acknowledges and agrees that:

         (i)     this Indenture, as originally executed and delivered by the
     parties hereto, does not create any Lien on any property or securities
     which secures the Indenture Obligations or this Indenture;

         (ii)    the Existing Security Documents, when executed and delivered by
     the parties thereto, will comply with the provisions of Section 4.12;

         (iii)   the Existing Security Documents provide, and any Security
     Document that becomes effective after the Issue Date, may provide, that the
     Liens created thereby or thereunder automatically will be released and
     extinguished with respect to any property or security that is transferred
     or otherwise disposed of in accordance with the terms of the Existing
     Credit Facility, including any property

                                       99
<PAGE>

     or security that is the subject of a Major Asset Sale and is transferred to
     a Subject Asset Transferee;

         (iv)    without the necessity of any consent of or notice to the
     Trustee or any holder of Indenture Obligations, the Company and the
     Collateral Agent may amend, modify, supplement or terminate any Security
     Document as long as the Company remains in compliance with Section 4.12;

         (v)     as among the Trustee and the holders of Indenture Obligations
     and the lenders under the Existing Credit Facility and the Collateral
     Agent, those lenders and the Collateral Agent will have the sole ability to
     control and obtain remedies with respect to all Collateral (including on
     sale or liquidation of any Collateral after acceleration of the Notes, the
     Existing Credit Facility Obligations or the Existing ARCO Chemical Debt)
     without the necessity of any consent of or notice to the Trustee or any
     such holder;

         (vi)    any or all Liens granted under the Security Documents for the
     benefit of the Holders will be automatically released, without the
     necessity of any consent of the Trustee or any Holders, upon a release of
     such Lien or Liens pursuant to the terms of the Security Documents and the
     Existing Credit Facility or if such release is approved by the requisite
     lenders under the Existing Credit Facility.

         (vii)   the relative rights of the holders of Indenture Obligations and
     the holders of Indebtedness or other obligations secured by Liens on the
     Collateral are governed by, and are subject to the terms and conditions of,
     the Security Documents and not this Indenture; and

         (viii)  without the necessity of any consent of or notice to the
     Trustee or any holder of Indenture Obligations, the Company may, on behalf
     of itself or any of its Restricted Subsidiaries, request and instruct the
     Collateral Agent to, on behalf of each secured party under the Security
     Documents, (A) execute and deliver to the Company, for the benefit of any
     Person, such release documents as the Company may reasonably request, of
     all liens and security interests held by the Collateral Agent in such
     assets, and such Person shall be entitled to rely conclusively on such
     release document, and (B) deliver any such assets in the possession of the
     Collateral Agent to the Company.

     Section 14.02. Notice of Payment, Discharge or Defeasance. The Trustee and
each Holder, by its acceptance of a Note, agree that upon the payment in full or
discharge pursuant to Article 11 of the Indenture Obligations, the Trustee shall
without notice to or consent of any Holder, upon the written request of the
Company, certify to the Collateral Agent, in writing, that the Indenture
Obligations have been paid in full, or that this Indenture has been discharged
in accordance with Article 11.

duly executed, all as of the date first written above.

                            [REVERSE SIDE OF NOTE]

                           LYONDELL CHEMICAL COMPANY

                9 5/8% Senior Secured Note, Series A, due 2007


     (1) Principal and Interest. The Company agrees to pay the principal of this
Note on May 1, 2007.

     The Company agrees to pay interest on the principal amount of this Note on
each Interest Payment Date, as set forth below, at the rate of 9 5/8% per annum.

     Interest will be payable semi-annually (to the Holders of record of the
Notes (or any predecessor Notes) at the close of business on the Regular Record
Date immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing November 1, 1999.

     [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated May 17, 1999, among the Company, the Subsidiary
Guarantors party thereto and the Initial Purchasers named therein (the
"Registration Rights Agreement"). In the event that (i) the Company or the
Subsidiary Guarantors fail to file an Exchange Offer Registration Statement with
the SEC on or prior to the 90th day after the Issue Date, (ii) if the Exchange
Offer Registration Statement is not declared effective by the SEC on or prior to
the 210th day after the Issue Date, (iii) if the Exchange Offer is not
consummated on or before the 30th business day after the Exchange Offer
Registration Statement is declared effective, (iv) the Company and the
Subsidiary Guarantors are obligated to file the Shelf Registration Statement and
fail to file the Shelf Registration Statement with the SEC on or prior to the
30th day after such filing obligation arises, (v) the Company and the Subsidiary
Guarantors are obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 60th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Notes during the periods specified
in the Registration Rights Agreement, for such time of non-effectiveness or non-
usability (each, a "Registration Default"), the Company and the Subsidiary
Guarantors agree to pay to the Holder of this Note, if affected thereby,
liquidated damages ("Liquidated Damages") in an amount equal to $0.05 per week
per $1,000 in principal amount of this Note for each week or portion thereof
that the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Notes with respect to each subsequent 90 day period until
all Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.50 per week per $1,000 in principal amount of Notes. The Company
and the Subsidiary Guarantors shall not be required to pay Liquidated Damages
for more than one


                                      A-4
<PAGE>

Registration Default at any given time. Following the cure of all Registration
Defaults, the accrual of Liquidated Damages will cease.]./2/

     Interest on this Note will accrue from the most recent date to which
interest has been paid [on this Note or the Note surrendered in exchange
herefor]/1/ or, if no interest has been paid, from May 17, 1999; provided that,
if there is no existing default in the payment of interest and if this Note is
authenticated between a Regular Record Date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest and Liquidated Damages, to the
extent lawful, at a rate per annum equal to 1% per annum in excess of the rate
of interest applicable to the Notes.

     (2) Method of Payment. The Company will pay interest (except defaulted
interest) on the principal amount of the Notes on each May 1 and November 1 to
the Persons who are Holders (as reflected in the Register at the close of
business on the April 15 and October 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is canceled on registration of
transfer or registration of exchange after such Regular Record Date; provided
that, with respect to the payment of principal, the Company will make payment to
the Holder that surrenders this Note to any Paying Agent on or after May 1,
2007.

     The Company will pay principal, premium, if any, and interest and
Liquidated Damages, if any, in money of the United States that at the time of
payment is legal tender for payment of public and private debts.  Payments
(including principal, premium, if any, and interest and Liquidated Damages, if
any) in respect of the Notes represented by the Global Notes, the Holders of
which have given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Company will make all payments of principal, premium, if any, and interest
and Liquidated Damages, if any, at the office or agency maintained by the
Company for such purposes in The City of New York or, at the Company's option,
by mailing a check to each such Holder's registered address. If a payment date
is a date other than a Business Day, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

     (3) Paying Agent and Registrar. Initially, the Trustee will act as Paying
Agent and Registrar. The Company may change any Paying Agent or Registrar upon
written notice thereto. The Company, any Subsidiary or any Affiliate of any of
them may act as Paying Agent, Registrar or co-registrar.

     (4) Indenture; Limitations. The Company issued the Notes under an Indenture
dated as of May 17, 1999 (the "Indenture"), among the Company, the Subsidiary

- ----------------
/2/ Include only for Initial Note.

                                      A-5
<PAGE>

Guarantors and The Bank of New York, as trustee (the "Trustee"). Capitalized
terms herein are used as defined in the Indenture unless otherwise indicated.
The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 (the "TIA").
The Notes are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of all such terms. To the extent permitted
by applicable law, in the event of any inconsistency between the terms of this
Note and the terms of the Indenture, the terms of the Indenture shall control.

     The Notes are secured senior obligations of the Company. The Indenture
limits the initial aggregate principal amount of the Notes to $900,000,000 but
permits the issuance of Additional Notes subject to compliance with the
covenants contained in the Indenture and except as may be limited by applicable
law; provided that the aggregate principal amount of Senior Secured Notes
outstanding at any time shall not exceed $1.9 billion.

     (5) Optional Redemption. The Series A Senior Secured Notes will be
redeemable, in whole, at any time, or in part, from time to time, at the option
of the Company upon not less than 30 nor more than 60 days' notice at a
redemption price equal to the Make-Whole Price (as defined in the Indenture).

     If less than all the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot
or by such method as the Trustee shall deem fair and appropriate; provided that
no Notes of $1,000 or less shall be redeemed in part.

     Notices of redemption shall be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each Holder of Notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed.  A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if any, cease to accrue on Notes or portions of them called
for redemption.

     (6) Repurchase upon a Change in Control and Sale of Assets. Upon the
occurrence of (a) a Change in Control, each Holder shall have the right to
require that the Company repurchase such Holder's Notes at a purchase price in
cash equal to 101% of the principal amount thereof on the date of purchase, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase and (b) an Asset Sale, the Company may be obligated to make an offer to
purchase on a pro rata basis from the Holders the Notes with the Excess Proceeds
of such Asset Sales at a purchase price equal to 100% of the principal amount of
such Notes plus accrued interest and Liquidated Damages, if any, to the date of
purchase.

     (7) Denominations; Transfer; Exchange. The Notes are in fully registered
form without coupons, in denominations of $1,000 and any integral multiples of
$1,000.

                                      A-6
<PAGE>

A Holder may register the transfer or exchange of Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture.

     (8)  Persons Deemed Owners. A Holder may be treated as the owner of a Note
for all purposes.

     (9)  Unclaimed Money. If money for the payment of principal, premium, if
any, or interest and Liquidated Damages, if any, remains unclaimed for two
years, the Trustee and the Paying Agent will pay the money back to the Company
at its written request. After that, Holders entitled to the money must look to
the Company for payment, unless an abandoned property law designates another
Person, and all liability of the Trustee and such Paying Agent with respect to
such money shall cease.

     (10) Discharge Prior to Redemption or Maturity. If the Company irrevocably
deposits, or causes to be deposited, with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of and premium, if
any, and accrued interest and Liquidated Damages on the Notes (a) to redemption
or maturity, the Company will be discharged from the Indenture and the Notes,
except in certain circumstances for certain sections thereof, and (b) to
redemption or maturity, the Company will be discharged from certain covenants
set forth in the Indenture.

     (11) Amendment; Supplement; Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
Outstanding, and any existing Default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding. Without notice to or the consent of any
Holder, the parties thereto may amend the Indenture or the Notes to the extent
set forth in the Indenture.

     (12) Restrictive Covenants. The Indenture contains certain covenants,
including, without limitation, covenants with respect to the following matters:
(i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted
Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with
Affiliates; (vi) Liens; (vii) No Amendments to Subordination Provisions; (viii)
repurchase of Notes upon a Change in Control; (ix) Sale and Leaseback
Transactions; (x) Subsidiary Guarantees; and (xi) consolidation, merger and sale
of assets. Within 120 days after the end of each fiscal year, the Company must
report to the Trustee on compliance with such limitations.

     (13) Successor Persons. When a successor person or other entity (other than
a Subsidiary of the Company) assumes all the obligations of its predecessor
under the Notes and the Indenture, the predecessor person will be released from
those obligations.

     (14) Remedies for Events of Default. If an Event of Default (other than an
Event of Default specified in Section 6.01(g) or (h) of the Indenture that
occurs with respect to the Company or a Subsidiary Guarantor) occurs and is
continuing under this Indenture, then in every such case the Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding Notes,
by written notice to the Company (and to the Trustee if


                                      A-7
<PAGE>

such notice is given by the Holders), may, and the Trustee at the written
request of such Holders shall, declare the principal of, premium, if any, and
accrued interest and Liquidated Damages, if any, on all of the Outstanding Notes
to be immediately due and payable. Upon a declaration of acceleration, such
principal of, premium, if any, and accrued interest and Liquidated Damages, if
any, shall be immediately due and payable. If an Event of Default specified in
Section 6.01(g) or (h) of the Indenture occurs with respect to the Company or a
Subsidiary Guarantor, the principal of, premium, if any, and accrued interest
and Liquidated Damages, if any, on the Outstanding Notes shall ipso facto become
and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holder. The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes by written notice to the
Company and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences if (1) all existing Events of
Default, other than the nonpayment of the principal of, premium, if any, and
interest and Liquidated Damages, if any, on the Notes that have become due
solely by such declaration of acceleration, have been cured or waived and (2)
the recission would not conflict with any judgment or decree of a court of
competent jurisdiction.

     Holders may not enforce the Indenture, the Notes or the Subsidiary
Guarantees except as provided in the Indenture. The Trustee may require security
or indemnity satisfactory to it before it enforces the Indenture, the Notes or
the Subsidiary Guarantees. The Holders of at least a majority in aggregate
principal amount of the Notes then Outstanding may direct the Trustee in the
exercise of any trust or power in accordance with the terms of the Indenture.

     (15) Security. In order to secure the Indenture Obligations, the Company
and certain of its Restricted Subsidiaries have entered into the Security
Documents. The Indenture Obligations shall be secured by Liens on the Collateral
in accordance with the terms and provisions of the Security Documents. The
Indenture requires that Holders of the Notes be granted a lien equally and
ratably with any lien granted on additional assets to secure the holders of
Existing Credit Facility Obligations subsequent to the Issue Date. Each Holder
of this Note, by accepting the same, agrees that (i) the Existing Security
Documents provide, and any Security Document that becomes effective after the
Issue Date, may provide, that the Liens created thereby or thereunder
automatically will be released and extinguished with respect to any property or
security that is transferred or otherwise disposed of in accordance with the
terms of the Existing Credit Facility, including any property or security that
is the subject of a Major Asset Sale and is transferred to a Subject Asset
Transferee; (ii) without the necessity of any consent of or notice to the
Trustee or any holder of Indenture Obligations, the Company and the Collateral
Agent may amend, modify, supplement or terminate any Security Document as long
as the Company remains in compliance with the Indenture; (iii) as among the
Trustee and the holders of Indenture Obligations and the lenders under the
Existing Credit Facility and the Collateral Agent, those lenders and the
Collateral Agent will have the sole ability to control and obtain remedies with
respect to all Collateral (including on sale or liquidation of any Collateral
after acceleration of the Notes, the Existing Credit Facility Obligations or the
Existing ARCO Chemical Debt) without the necessity of any consent of or notice
to the Trustee or any such holder; (iv) any or all Liens granted under the
Security Documents for the benefit of the Holders will be automatically
released, without the necessity of any consent of the Trustee or the Holders,
upon a release of such Lien or

                                      A-8
<PAGE>

Liens pursuant to the terms of the Security Documents and the Existing Credit
Facility or if such release is approved by the requisite lenders under the
Existing Credit Facility; (v) the relative rights of the holders of Indenture
Obligations and the holders of Indebtedness or other obligations secured by
Liens on the Collateral are governed by, and are subject to the terms and
conditions of, the Security Documents and not this Indenture; and (vi) without
the necessity of any consent of or notice to the Trustee or any holder of
Indenture Obligations, the Company may, on behalf of itself or any of its
Restricted Subsidiaries, request and instruct the Collateral Agent to, on behalf
of each secured party under the Security Documents, (A) execute and deliver to
the Company, for the benefit of any Person, such release documents as the
Company may reasonably request, of all liens and security interests held by the
Collateral Agent in such assets, and such Person shall be entitled to rely
conclusively on such release document, and (B) deliver any such assets in the
possession of the Collateral Agent to the Company. From and after the date when
all liens granted in favor of the holders of Existing Credit Facility
Obligations are released, the provisions regarding security described above will
no longer apply.

     (16) Subsidiary Guarantees. Each Subsidiary Guarantor irrevocably and
unconditionally guarantees, jointly and severally, on a senior basis, the full
and punctual payment (whether at Stated Maturity, upon acceleration, optional
redemption, upon repurchase following a Change of Control Offer or an Asset Sale
Offer or otherwise) of the principal of, premium, if any, and interest and
Liquidated Damages, if any, on, and all other amounts payable under, this Note
provided for under this Indenture, and the full and punctual payment of all
other amounts payable by the Company under the Indenture; provided that,
notwithstanding anything to the contrary herein, the aggregate amount of the
Obligations guaranteed under the Indenture by any Subsidiary Guarantor shall be
limited in amount to the maximum amount that would not render such Subsidiary
Guarantor's obligations subject to avoidance under the applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable
provision of any applicable state law.

     (17) Additional Subsidiary Guarantees. If any of the Company's Restricted
Subsidiaries shall Guarantee or secure the payment of any other Indebtedness of
the Company or any of its Restricted Subsidiaries, then, subject to certain
exceptions specified in the Indenture, such Restricted Subsidiary shall become a
Subsidiary Guarantor by executing a supplemental indenture.

     (18) Trustee Dealings with Company. The Trustee under the Indenture, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may make loans to, accept deposits from, perform services for, and otherwise
deal with, the Company and its Affiliates as if it were not the Trustee.

     (19) Authentication. This Note shall not be valid until the Trustee signs
the certificate of authentication on this Note.

     (20) Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts

several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion with respect to some matters and one or more other such Persons as to
other matters, and any such Person may certify or give an opinion as to such
matters in one or several documents.

     Any certificate or opinion of an Officer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such Officer knows that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such certificate or opinion of counsel may
be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an Officer or Officers to the effect that the

Company, unless such counsel knows that the certificate or opinion or
representations with respect to such matters are erroneous.

this Indenture

                                       30
<PAGE>

to be given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee, and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 7.01) conclusive in favor of
the Trustee, the Company and any other obligor upon the Notes, if made in the
manner provided in this Section 1.08.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership or
other entity, on behalf of such corporation or partnership or other entity, such
certificate or affidavit shall also constitute sufficient proof of such Person's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the person executing the same, may also be proved in any
other manner that the Trustee deems sufficient.

     (c)  The ownership of Notes shall be proved by the Register.

     (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Note shall bind the Holder of every Note
issued upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done or suffered to be done by the Trustee, the Company or
any other obligor on the Notes in reliance thereon, whether or not notation of
such action is made upon such Note.

     (e)  (i) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in Section
1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date (or their duly designated proxies), and
no other Holders, shall be entitled to take the relevant action, whether or not
such Persons remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph  (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Notes on the date such action is taken. Promptly after any
record date is set

                                       31
<PAGE>

pursuant to this paragraph, the Company, at its own expense, shall cause notice
of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder in the
manner set forth in Section 1.10.

     (ii) The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to join in the giving or
making of (w) any Notice of Default, (x) any declaration of acceleration
referred to in Section 6.02, (y) any request to institute proceedings referred
to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each
case with respect to Notes. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Notes on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the expense of the Company, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be given to
the Company in writing and to each Holder in the manner set forth in Section
1.10.

     (iii) With respect to any record date set pursuant to this Section 1.08,
the party hereto that sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Company or the
Trustee, whichever such party is not setting a record date pursuant to this
Section 1.08(e) in writing, and to each Holder in the manner set forth in
Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     (iv) Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Note may do so with regard to
all or any part of the principal amount of such Note or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     Section 1.09.  Notices, Etc., to Trustee and Company.  Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or

     Section 1.10.  Notices to Holders; Waivers.  Where this Indenture provides
for notice to Holders of any event, such notice shall be deemed to have been
given upon the mailing by first class mail, postage prepaid, of such notices to
Holders at their registered addresses as recorded in the Register, not later
than the latest date, and not earlier than the earliest date, prescribed herein
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail notice of any event as
required by any provision of this Indenture, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably
withheld) shall constitute a sufficient notification for every purpose
hereunder.

     Section 1.11.  Effect of Headings and Table of Contents.  The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 1.12. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its respective successors and assigns,
whether so expressed or not.

     Section 1.13. Separability Clause. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 1.14.  Benefits of Indenture.  Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their

successors hereunder, any Paying Agent and the Holders, any benefit or any legal
or equitable right, remedy or claim under this Indenture.

     Section 1.15.  Governing Law.  THIS INDENTURE, THE NOTES AND THE SUBSIDIARY
GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY.  TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY,
THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY
THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THIS INDENTURE OR THE NOTES.

     Section 1.16. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest and Liquidated Damages, if any, or principal and premium (if any)
need not be made on such date, but may be made on the next succeeding Business
Day with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

     Section 1.17.  No Personal Liability of Directors, Officers, Employees,
Incorporators and Stockholders.  No director, officer, employee, incorporator,
shareholder or other holder of Equity Interests of the Company or the Subsidiary
Guarantors, as such, shall have any liability for any obligations of the Company
or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

     Section 1.18.  Exhibits and Schedules.  All exhibits and schedules attached
hereto are by this reference made a part hereof with the same effect as if
herein set forth in full.

     Section 1.19.  Counterparts.  This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

3.14(g), unless and until (i) an Initial Note or any Additional Note is sold

to an effective Exchange Offer Registration Statement pursuant to the
Registration Rights Agreement, each U.S. Global Note and U.S. Physical Note
shall bear the following legend set forth below (the "Private Placement Legend")
on the face thereof:

THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY
STATE OR OTHER JURISDICTION, AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS
ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

(1)  REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (As defined in
     Rule 144A under the Securities Act) (A "QIB")

(2)  AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A)
     TO THE COMPANY, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
     QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB TO WHOM

     OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND

(3)  AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST
     HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER

     (b)  Each Global Note, whether or not an Initial Note or Additional Note,
shall also bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR
THEIR AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME
AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE
TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE

                                   ARTICLE 3

                                   The Notes

     Section 3.01.  Title and Terms.  The aggregate principal amount of Notes
that may be authenticated and delivered and Outstanding under this Indenture is
initially limited to $1,000,000,000, but may be increased, subject to compliance
with the covenants contained in Article 4 below and the conditions set forth in
Section 3.03, and except as may be limited by applicable law; provided that the
aggregate principal amount of Senior Secured Notes outstanding at any time shall
not exceed $1.9 billion. The Initial Notes will

                                       37
<PAGE>

be issued in an aggregate principal amount of $1,000,000,000. All the Original
Notes shall vote and consent together on all matters as one class, and none of
the Original Notes will have the right to vote or consent as a class separate
from one another on any matter. Subject to the covenants contained in Article 4
below, the Company may issue Additional Notes hereunder. Additional Notes
(including any Exchange Notes issued in exchange therefor) shall vote (or
consent) as a class with the other Notes and otherwise be treated as Notes for
all purposes of this Indenture.

     The Notes shall be known and designated as the "9 7/8% Senior Secured
Notes, Series B, Due 2007" of the Company. The final Stated Maturity of the
Notes shall be May 1, 2007. Interest on the Outstanding principal amount of
Notes will accrue, subject to Section 3.11, at the rate of 9 7/8% per annum and
will be payable semiannually in arrears on May 1 and November 1 in each year,
commencing on November 1, 1999, to Holders of record at the close of business on
the immediately preceding April 15, and October 15, respectively (each such
April 15 and October 15 a "Regular Record Date"). Interest on the Original Notes
will accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid, from May 17, 1999, and interest
on any Additional Notes (and Exchange Notes issued in exchange therefor) will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid on such Additional Notes, from the
date of issuance of such Additional Notes; provided that if any Note is
surrendered for exchange on or after a record date for an Interest Payment Date
that will occur on or after the date of such exchange, interest on the Note
received in exchange thereof will accrue from the date of such Interest Payment
Date. The Company will pay interest on overdue principal and, to the extent
lawful, on overdue installments of interest and Liquidated Damages, if any, at a
rate of 1% per annum in excess of the interest rate referred to above.

     The principal of, and premium, if any, and interest and Liquidated Damages,
if any, on the Notes shall be payable at the Corporate Trust Office or at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York (each, a "Place of Payment") in the manner
provided in Section 4.01(b); provided, however, that, under the circumstances
set forth in Section 4.01(b), payment of interest and Liquidated Damages on a
Note may be made by wire transfer of immediately available funds to the account
specified by the Holder of a Global Note or by check mailed to the address of
the Person entitled thereto as such address shall appear in the Register.

     Section 3.02.  Denominations.  The Notes shall be issuable only in
registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof.

     Section 3.03. Execution, Authentication and Delivery and Dating. The Notes
shall be executed on behalf of the Company by an Officer of such Company. The
signature of such Officer on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signature of an individual who was at
any time a proper Officer of the Company shall bind the Company, notwithstanding
that such individual has ceased to hold such office prior to the authentication
and delivery of such Notes or did not hold such office at the date of such
Notes.

                                       38
<PAGE>

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes for original issue in the aggregate principal amount not to exceed
$1,000,000,000 and (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Company in the form of an Officer's
Certificate (an "Authentication Order"), and in the case of clause (ii), upon
receipt by the Trustee of an Opinion of Counsel confirming that the Holders of
the Outstanding Notes will be subject to federal income tax in the same amounts,
in the same manner and at the same times as would have been the case if such
Additional Notes were not issued. Such Officer's Certificates shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes, Additional Notes or
Exchange Notes, that, in the case of Additional Notes, (x) the issuance of such
Notes does not contravene any provision of Article 4 of this Indenture and (y)
after giving effect to such Issuance of Additional Notes, the aggregate
principal amount of Senior Secured Notes outstanding does not exceed $1.9
billion, whether the Notes are to be issued as one or more Global Notes or
Physical Notes, the name or names of the Initial Holder or Holders and such
other information as the Company may include or the Trustee may reasonably
request.

     All Notes shall be dated the date of their authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Note a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

     Section 3.04.  Temporary Notes.    Until definitive Notes are ready for
delivery, the Company may prepare and upon receipt of an Authentication Order
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company consider appropriate for temporary Notes. If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable
delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the
office or agency of the Company in a Place of Payment, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Company shall execute and upon receipt of an Authentication Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes of the same series and tenor.

     Section 3.05.  Registration, Registration of Transfer and Exchange.  The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Register") in

                                       39
<PAGE>

which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Notes and of transfers of Notes. The
Trustee is hereby appointed "Registrar" for the purpose of registering Notes and
transfers of Notes as herein provided.

     Upon surrender for transfer of any Note at the office or agency of the
Company in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes, of any authorized denominations and of a
like aggregate principal amount.

     At the option of the Holder, Notes may be exchanged for other Notes, of any
authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive; provided that no exchange of Initial Notes or
Initial Additional Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the SEC and the
Trustee shall have received an Officer's Certificate confirming that the
Exchange Offer Registration Statement has been declared effective by the SEC and
an exchange offer thereunder has been consummated.  The Initial Notes or
Additional Notes to be exchanged for the Exchange Notes shall be canceled by the
Trustee.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes under this
Section 3.05.

     Section 3.06.  Mutilated, Destroyed, Lost and Stolen Notes.  If (a) any
mutilated Note is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b)  there is delivered to the Company and the Trustee such security
or indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Company or the Trustee that such Note has been
acquired by a bona fide purchaser, the Company shall execute and upon receipt of
an Authentication Order the Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
Outstanding.

                                       40
<PAGE>

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and ratably with
any and all other Notes duly issued hereunder.

     The provisions of this Section 3.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     Section 3.07.  Payment of Interest Rights Preserved.  Interest and
Liquidated Damages on any Note that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest and Liquidated Damages
specified in Section 3.01.

     Any interest and Liquidated Damages on any Note that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder; and such Defaulted Interest shall be paid by the Company, as
provided in 3.07(a) or 3.07(b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Notes (or their respective Predecessor Notes) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as provided in this Section 3.07(a).  Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest,
the amount thereof and the Special Record Date and payment date therefor to be
mailed, first class postage prepaid, to each Holder at such Holder's address as
it appears in the

                                       41
<PAGE>

Register, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Notes (or their respective Predecessor Notes) are registered on
such Special Record Date and shall no longer be payable pursuant to the
following 3.07(b).

     (b)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause (b), such payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest (including
any Liquidated Damages) accrued and unpaid, and to accrue, that were carried by
such other Note.

     Section 3.08.  Persons Deemed Owners.   Prior to due presentment of a Note
for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of (and premium, if any, on) and (subject to Section 3.07) interest
and Liquidated Damages, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Company, the
Subsidiary Guarantors, the Trustee or any agent of the Company,  the Subsidiary
Guarantors or the Trustee shall be affected by notice to the contrary.

     Section 3.09. Cancellation. All Notes surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and, if not already canceled,
shall be promptly canceled by it. The Company may at any time deliver to the

     Section 3.12.  CUSIP Numbers.  The Company in issuing the Notes may use
"CUSIP" or "CINS" numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such "CUSIP" or "CINS" numbers in
addition to serial numbers in notices of redemption, repurchase or other notices
to Holders as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such "CUSIP" or "CINS"
numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Notes, and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the "CUSIP" or
"CINS" numbers.

     Section 3.13.  Book-entry Provisions for Global Notes.

     (a)  Each Global Note initially shall (i) be registered in the name of the
Depositary for such Global Notes or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) to the
extent relevant thereto, bear legends as set forth in Section 2.03.  None of the
Company or the Subsidiary Guarantors, nor any of their agents shall have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of beneficial ownership interests of, a Global Note, or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note, and the
Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Subsidiary
Guarantors, the Trustee or any agent of the Company, the Subsidiary Guarantors
or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a beneficial owner of any Note.  The registered Holder
of a Global Note may grant proxies and otherwise authorize any person, including
Agent Members and persons that may hold interests through Agent Members, to take
any action which a Holder is entitled to take under this Indenture or the Notes.

     (b)  Interests of beneficial owners in a Global Note may be transferred in
accordance with the applicable rules and procedures of the Depositary and the
provisions of Section 3.14.  Transfers of a Global Note shall be limited to
transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees, except (i) upon request of an Agent
Member (for itself or on behalf of a beneficial holder) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary
procedures of the Depositary and (ii) Physical Notes shall be transferred to
beneficial owners in exchange for their beneficial interests in the Global Notes
in the event that (A) the Depositary (1) notifies the Company that it is
unwilling or unable to continue as Depositary for the applicable Global Note and
a successor depositary is not appointed by the Company within 90 days or (2)
the Depositary ceases to be a "Clearing Agency" registered under the Exchange
Act , (B) the Company, at its option,

                                       43
<PAGE>

notifies the Trustee in writing that it elects to cause the issuance of Physical
Notes under this Indenture or (C) there shall have occurred and be continuing a
Default or Event of Default. In connection with any transfer or exchange of a
portion of the beneficial interest in any Global Note to beneficial owners for
Physical Notes pursuant to paragraph (b) of this Section 3.13, the Registrar
shall record on its books and records (and make a notation on the Global Note
of) the date and a decrease in the principal amount of such Global Note in an
amount equal to the beneficial interest in the Global Note being transferred,
and the Company shall execute, and the Trustee shall authenticate and deliver,
one or more Physical Notes of like tenor and principal amount of authorized
denominations. In connection with a transfer of an entire Global Note to
beneficial owners pursuant to clause (ii) of this paragraph (b), the applicable
Global Note shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall authenticate and deliver,
to each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the applicable Global Note, an equal aggregate principal
amount at maturity of Physical Notes of authorized denominations.

     (c)  Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

     (d)  The Company, the Subsidiary Guarantors, any other obligor upon the
Notes or the Trustee, in the discretion of any of them, may treat as the Act of
a Holder any instrument or writing of any Person that is identified by the
Depositary as the owner of a beneficial interest in the Global Note, provided
that the fact and date of the execution of such instrument or writing is proved
in accordance with Section 1.08(b).

     (e)  Any U.S. Physical Note delivered in exchange for an interest in the
U.S. Global Note pursuant to paragraph (b) of this Section shall, except as
otherwise provided in Section 3.14, bear the Private Placement Legend.

     Section 3.14. Transfer Provisions. Unless and until (i) an Initial Note or
any Initial Additional Note is sold pursuant to an effective registration
statement, whether pursuant to the Registration Rights Agreement or otherwise,
or (ii) an Initial Note or any Initial Additional Note is exchanged for an
Exchange Note in the Exchange Offer pursuant to an effective Registration
Statement pursuant to the Registration Rights Agreement, the following
provisions shall apply:

     (a)  General. The provisions of this Section 3.14 shall apply to all
transfers involving any Physical Note and any beneficial interest in any Global

this Indenture (including Section 3.05 and Section 3.13) and,

                                       44

     (i)  if such transfer is being made by a proposed transferor who has
checked the box provided for on the form of such Note stating, or has otherwise
certified to the Company and the Registrar in writing, that the sale has been
made in compliance with the provisions of Rule 144A to a transferee who has
signed the certification provided for on the form of such Note stating, or has
otherwise certified to the Company and the Registrar in writing, that it is
purchasing such Note for its own account or an account with respect to which it
exercises sole investment discretion and that it and any such account is a QIB
within the meaning of Rule 144A, and is aware that the sale to it is being made
in reliance on Rule 144A and acknowledges that it has received such information
regarding the Company as it has requested pursuant to Rule 144A or has
determined not to request such information and that it is aware that the
transferor is relying upon its foregoing representations in order to claim the
exemption from registration provided by Rule 144A; and

     (ii)  if the proposed transferee is or is acting through an Agent Member,
and the Note to be transferred consists of (A) a Physical Note that after
transfer is to be evidenced by an interest in a Global Note or (B) a beneficial
interest in a Global Note that after the transfer is to be evidenced by a
Physical Note, upon receipt by the Registrar of written instructions given in
accordance with the Depositary's and the Registrar's procedures,

     (I) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and an increase in the
principal amount of the transferee Global Note or (y) deliver Physical Notes, in
each case in an amount equal to the principal amount of the Physical Note or
such beneficial interest in such transferor Global Note to be transferred, and
(II) the Trustee shall (x) cancel the Physical Note so transferred or (y)
reflect on its books and records (and make a notation on the relevant Global
Note of) the date and a decrease in the principal amount of such transferor
Global Note, as the case may be.

     (c)  Transfers pursuant to Rule 144 and transfer to Lyondell.  With respect
to the registration of any proposed transfer of a Note that is a Restricted
Security (i) pursuant to the exemption from registration under the Securities
Act provided by Rule 144 thereunder or (ii) to the Company, the Register shall
register such transfer if it complies with all other requirements of this
Indenture (including Section 3.05 and Section 3.13) and,

     (A)  if such transfer is being made by a proposed transferor who has
checked the box provided for on the form of such Note stating, or has otherwise
certified to the Company and the Registrar in writing, that the sale has been
made in compliance with the provisions of Rule 144 or that such sale has been
made to the Company; and

     (B)  if the proposed transferee is not the Company and is or is acting
through an Agent Member, and the Note to be transferred consists of (1) a
Physical Note that after transfer is to be evidenced by an interest in a Global
Note or (2) a beneficial interest in a Global Note that after the transfer is to
be

                                       45
<PAGE>

evidenced by a Physical Note, upon receipt by the Registrar of written
instructions given in accordance with the Depositary's and the Registrar's
procedures,

(I) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and an increase in the
principal amount of the transferee Global Note or (y) deliver Physical Notes, in
each case in an amount equal to the principal amount of the Physical Note or
such beneficial interest in such transferor Global Note to be transferred, and
(II) the Trustee shall (x) cancel the Physical Note so transferred or (y)
reflect on its books and records (and make a notation on the relevant Global

the Physical Note so transferred or (y) reflect on its books and records (and
make a notation on the relevant Global Note of) the date and a decrease in the
principal amount of such transferor Global Note, as the case may be.

     The Company and the Trustee may require additional certifications or other
information to confirm that any proposed transfer is being made pursuant to Rule
144 under the Securities Act.

     (d)  Other Transfers. The Registrar shall effect and register, upon receipt
of a written request from the Company to do so, a transfer not otherwise
permitted by this Section 3.14, such registration to be done in accordance with
the otherwise applicable provisions of this Section 3.14, upon the furnishing by
the proposed transferor or transferee of a written opinion of counsel (which
opinion and counsel are satisfactory to the Company and the Trustee) to the
effect that, and such other certifications or information as the Company may
require to confirm that, the proposed transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act.

     A Note that is a Restricted Security may not be transferred other than as
provided in this Section 3.14.  A beneficial interest in a Global Note that is a
Restricted Security may not be exchanged for a beneficial interest in another
Global Note other than through a transfer in compliance with this Section 3.14.

     (e)  Limitation on Issuance of Physical Notes. No Physical Note shall be
exchanged for a beneficial interest in any Global Note, except in accordance
with Section 3.13 and this Section 3.14.

of Notes not bearing the Private Placement Legend, the Registrar shall deliver
Notes that do not bear the Private Placement Legend. Upon the transfer, exchange
or replacement of Notes bearing the Private Placement Legend, the Registrar
shall deliver only Notes that bear the Private Placement Legend, unless (i) the
requested transfer is after the relevant Resale Restriction Termination Date
with respect to such Notes, (ii) upon written request of the Company after there
is delivered to the Registrar an opinion of counsel (which opinion and counsel
are satisfactory to the Company and the Trustee) to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act, or (iii) such
Notes are sold or exchanged pursuant to an effective registration statement
under the Securities Act.

     (h)  General. By its acceptance of any Note bearing the Private Placement
Legend, each Holder of such a Note acknowledges the restrictions on transfer of
such Note set forth in this Indenture and in the Private Placement Legend and
agrees that it will transfer such Note only as provided in this Indenture.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.13 or this Section 3.14 (including
all Notes received for transfer pursuant to this Section 3.14). The Company
shall have the right to require the Registrar to deliver to the Company, at the
Company' expense, copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

     In connection with any transfer of any Note, the Trustee, the Registrar,
the Company and the Subsidiary Guarantors shall be entitled to receive, shall be
under no duty to inquire into, may conclusively presume the correctness of, and
shall be fully protected in relying upon the certificates, opinions and other
information referred to herein (or in the forms provided herein, attached hereto
or to the Notes, or otherwise) received from any Holder and any transferee of
any Note regarding the validity, legality and due authorization of any such
transfer, the eligibility of the transferee to receive such Note and any other
facts and circumstances related to such transfer.

     (i)  Certain Additional Terms Applicable to Physical Notes. Any transferee
entitled to receive a Physical Note may request that the principal amount
thereof be evidenced by one or more Physical Notes in any authorized
denomination or denominations and the Registrar shall comply with such request
if all other transfer restrictions are satisfied.

                                   ARTICLE 4

                                   Covenants

     Section 4.01.  Payment of Principal, Premium and Interest.  (a) The Company
will duly and punctually pay the principal of (and premium, if any) and interest
and Liquidated Damages, if any, on the Notes in accordance with the terms of the
Notes and this Indenture. An installment of principal (and premium, if any) or
interest and Liquidated Damages shall be considered paid on the date it is due
if the Trustee or Paying Agent or Paying Agents hold on that date money
designated for and sufficient to pay the installment.

                                       47
<PAGE>

     (b)  Payments (including principal, premium, if any, interest and
Liquidated Damages, if any) in respect of the Notes represented by the Global
Notes, the Holder of which has given wire transfer instructions on or prior to
the relevant record date, shall be made by wire transfer of immediately
available funds to the accounts specified by the Global Note Holder. With
respect to Physical Notes, the Company will make all payments of principal,
premium, if any, interest and Liquidated Damages, if any, at the office or
agency maintained by the Company in The City of New York referred to in Section
4.02 or, at the option of the Company, by mailing a check to each such Holder's
registered address.

     Section 4.02.  Maintenance of Office or Agency.  The Company will maintain
in the Borough of Manhattan, The City of New York an office or agency where
Notes may be presented or surrendered for payment, where Notes may be
surrendered for transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and of
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain such office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee. The
Company hereby designates the Corporate Trust Office as an initial Place of
Payment and as such office of the Company in the Borough of Manhattan, The City
of New York, and appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands so long as such Corporate Trust
Office remains a Place of Payment.

     Section 4.03. Money for Payments to Be Held in Trust. If the Company shall
at any time act as its own Paying Agent, it will, on or before each due date of
the principal of (and premium, if any) or interest and Liquidated Damages, if
any, on, any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest and Liquidated Damages, if any, so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, it will, prior to
each due date of the principal of (and premium, if any) or interest and
Liquidated Damages, if any, on, any Notes, deposit with a Paying Agent a sum
sufficient to pay the principal (and premium, if any) or interest and Liquidated
Damages, if any, so becoming due, such sum to be held in trust for the benefit
of the Persons entitled to such principal, premium or interest and Liquidated
Damages, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, the Company will
cause any Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 4.03, that such Paying Agent will:

     (a)  hold all sums held by it for the payment of principal of (and premium,
if any) or interest and Liquidated Damages, if any, on Notes in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

                                       48
<PAGE>

     (b)  give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any such payment of principal (and
premium, if any) or interest and Liquidated Damages, if any;

     (c)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d)  acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture and TIA relating to the duties, rights and
liabilities of such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest and Liquidated Damages, if any, on any Note and remaining unclaimed
for two years after such principal (and premium, if any) or interest and
Liquidated Damages, if any, has become due and payable shall be paid in the
appropriate proportion to the Company upon a Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease.

     Section 4.04.  SEC Reports. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes issued hereunder are outstanding,
the Company will furnish to each Trustee and the Holders of Notes (i) all
quarterly and annual financial information that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were
required to file such Forms, including a "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and, with respect to the
annual information only, a report thereon by the Company's certified independent
accountants and (ii) all current reports that would be required to be filed with
the SEC on Form 8-K if the Company were required to file such reports. In
addition, whether or not required by the rules and regulations of the SEC, the
Company will file a copy of all such information and reports with the SEC for
public availability and make such information available to securities analysts
and prospective investors upon request.

     (b)  For so long as any Notes remain outstanding, the Company will furnish
to the Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

                                       49
<PAGE>

     (c)  All obligors on the Notes will comply with Section 314(a) of the TIA.

     (d)  The Company shall promptly mail copies of all such annual reports,
information, documents and other reports provided to the Trustee pursuant to
clauses  (a) and (c) hereof to the Holders at their addresses appearing in the
Register maintained by the Registrar.

     (e)  Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

     Section 4.05.  Certificates to Trustee. (a) The Company will deliver to the
Trustee within 120 days after the end of each fiscal year of the Company a
certificate from the principal executive, financial or accounting officer of the
Company stating that such officer has conducted or supervised a review of the
activities of the Company and its Restricted Subsidiaries and the Company's and
its Restricted Subsidiaries' performance under this Indenture and that, based
upon such review, to the best of such officer's knowledge, the Company has
fulfilled all obligations thereunder or, if there has been a default in the
fulfillment of any such obligation (determined without regard to any period of
grace or requirement of notice provided in this Indenture), specifying each such
default and the nature and status thereof.

     (b)  The Company will deliver to the Trustee, as soon as possible and in
any event within 30 days after the Company becomes aware of an Event of Default
or a Default, an Officer's Certificate setting forth the details of such Event
of Default or Default, and the action which the Company proposes to take or has
taken with respect thereto.

     (c)  The Company will deliver to the Trustee within 120 days after the end
of each fiscal year of the Company a written statement by the Company's
independent public accountants stating (i) that their audit examination has
included a review of the terms of this Indenture and the Notes as they relate to
accounting matters, and (ii) whether, in connection with their audit
examination, any Default has come to their attention and, if such a Default has
come to their attention, specifying the nature and period of the existence
thereof.

     Section 4.06.  Limitation on Indebtedness. (a) On or after the Issue Date:

     (i)  the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt);

     (ii) the Company will not, and will not permit any of its Restricted
Subsidiaries to, issue any Disqualified Stock (including Acquired Disqualified
Stock);

                                       50
<PAGE>

     (iii)  and the Company will not permit any of its Restricted Subsidiaries
that are not Subsidiary Guarantors to issue any shares of Preferred Stock
(including Acquired Preferred Stock);

provided, however, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired
Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
Letters of credit and bankers' acceptances shall be deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

     (b)  The foregoing provisions will not apply to:

     (i)  the incurrence by the Company of Indebtedness pursuant to the Existing
Credit Facility (and by its Subsidiaries of Guarantees thereof) in an aggregate
principal amount at any time outstanding not to exceed an amount equal to $3.87
billion less the aggregate amount of all mandatory repayments (other than
mandatory prepayments triggered solely by the issuance of Indebtedness or
Preferred Stock of a Finance Subsidiary to refinance the Existing Credit
Facility) applied to (x) repay loans (other than revolving credit loans)
outstanding thereunder or (y) permanently reduce the revolving credit
commitments thereunder;

     (ii)  the incurrence by the Company and the Subsidiary Guarantors of
Indebtedness represented by the Senior Secured Notes and Senior Subordinated
Notes issued on the Issue Date and the Subsidiary Guarantees thereof;

     (iii)  the incurrence by the Company and its Restricted Subsidiaries of
Existing Indebtedness (other than Indebtedness of the type described in clauses
(i), (ii) or (v) through (xii) of this covenant);

     (iv) the incurrence by the Company or any of its Restricted Subsidiaries
of any Permitted Refinancing in exchange for, or the net proceeds of which are
used to extend, refinance, renew, replace, defease or refund, Indebtedness that
was permitted to be incurred under the Fixed Charge Coverage Ratio test set
forth above or clauses (ii) or (iii) above or (xiii) or (xiv) below or this
clause (iv);

     (v)  the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Restricted
Subsidiaries; provided, however, that (i) if the Company or any Subsidiary
Guarantor is the obligor on such Indebtedness, such Indebtedness is expressly
subordinated to the prior payment in full in cash of all Obligations with

                                       51
<PAGE>

respect to the Notes or the Subsidiary Guarantee, as the case may be, and
(ii)(A) any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a Person other than the Company or a
Restricted Subsidiary and (B) any sale or other transfer of any such
Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary shall be deemed, in each case, to constitute an incurrence of such
Indebtedness by the Company or such Restricted Subsidiary, as the case may be;

Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company,

parenthetical included in the preceding sentence) will be deemed to constitute
Investments in an amount equal to the fair market value of such Investments at
the time of such designation (as conclusively determined by the Board of
Directors). Such designation will only be permitted if any such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. In the case of any
designation by the Company of a Person as an Unrestricted Subsidiary on the
first day that such Person is a Subsidiary of the Company in accordance with the
provisions of the Indenture, such designation shall be deemed to have occurred
for all purposes of the Indenture simultaneously with, and automatically upon,
such Person becoming a Subsidiary.

     (d)  Not later than the date of making any Restricted Payment, other than
those permitted by Sections 4.07(b)(ii)(x), 4.07(b)(vi), 4.07(b)(x) and

Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

affecting Restricted Subsidiaries and Joint Ventures.  (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
restriction on the ability of any Restricted Subsidiary to:

     (i)  (A) pay dividends or make any other distributions to the Company or
any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect

of any Person, other than the Person, or the property or assets of the Person,
so acquired;

     (f) customary non-assignment provisions in leases and other agreements
entered into in the ordinary course of business;

     (g) construction loans and purchase money obligations (including Capital
Lease Obligations) for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (iii) above on the
property so constructed or acquired;

     (h) in the case of clause (iii) above, restrictions contained in security
agreements or mortgages securing Indebtedness of a Restricted Subsidiary to the
extent such restrictions restrict the transfer of the property subject to such
security agreements or mortgages;

     (i) a Permitted Refinancing, provided that the restrictions contained in
the agreements governing such Permitted Refinancing are not materially more
restrictive, taken as a whole, than those contained in the agreements governing

Resolution);

     (j) customary restrictions on a Finance Subsidiary imposed in such Finance
Subsidiary's organizational documents or by the terms of its Preferred Stock;

Board Resolution);

     (m) existing restrictions with respect to a Specified Joint Venture or the
property or assets thereof or a Subsidiary of a Specified Joint Venture or the
property or assets thereof, in each case, at the time such Specified Joint
Venture first becomes a Restricted Subsidiary (except to the extent such
restrictions were put in place in connection with or in contemplation of such
Specified Joint Venture becoming a Restricted Subsidiary), which restrictions
are not applicable to any Person, or the properties or assets of any Person,
other than such Specified Joint Venture or the property or assets thereof or a
Subsidiary of such Specified Joint Venture or the property or assets thereof;
and

     (n) the Existing Credit Facility and related documentation as the same is
in effect on the Issue Date and as amended, modified, extended, renewed,
refunded, refinanced, restated or replaced from time to time; provided that the
Existing Credit Facility and related documentation as so amended, modified,
extended, reviewed, refunded, refinanced, restated or replaced is not materially
more restrictive, taken as a whole, as to the matters enumerated above than the
Existing Credit Facility and related documentation as in effect on the Issue
Date (as conclusively evidenced by a Board Resolution).

     For purposes of determining compliance with this covenant, in the event
that a restriction meets the criteria of more than one of the categories of
permitted restrictions described in clauses (a) through (n) above, the Company
shall, in its sole discretion, classify such restriction in any matter that
complies with this covenant and such restriction will be treated as existing
pursuant to the clauses designated by the Company.

     (b)  The Company will use best efforts (consistent with its contractual
obligations and fiduciary duties to any Joint Venture, in each case, as in
effect on the Issue Date) not to permit any of its Joint Ventures that are not
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any restriction on the ability of such Joint
Venture to:

     (i)  (A) pay dividends or make any other distributions to the Company or
any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect
to any other interest or participation in, or measured by, its profits or (B)
pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

     (ii)  make loans or advances to the Company or any of its Restricted
Subsidiaries; or

                                       62
<PAGE>

     (iii) transfer any of its properties or assets to the Company or any of its
Restricted Subsidiaries;

except for such restrictions existing under or by reason of:

     (a) such Joint Venture's joint venture agreement or its credit facility
(provided that in each case such restrictions are consistent with the past
practice of the Company);

     (b) in the case of any Joint Venture existing on the Issue Date, its
existing agreements as in effect on the date of the Indenture and as amended,
modified, extended, restated or replaced from time to time; provided that no
such amendment, modification, extension, restatement or replacement results in
agreements that are materially more restrictive, taken as a whole, as to the
matters enumerated above than the existing agreements as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution);

     (c) in the case of LCR, any instrument governing its Indebtedness; and

     (d) the restrictions described in clauses (d), (e), (f), (g), (h), (j), (k)
and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k) to a
Restricted Subsidiary were references to a Joint Venture).

     Section 4.09. Limitation on Sales of Assets. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless:

     (i)  the Company and/or the Restricted Subsidiary, as the case may be,
receives consideration at the time of such Asset Sale at least equal to the fair
market value (as conclusively evidenced by a Board Resolution set forth in an
Officers' Certificate delivered to the Trustees) of the assets or Equity
Interests issued or sold or otherwise disposed of; and

     (ii)   at least 80% of the consideration therefor received by the Company
and/or such Restricted Subsidiary is in the form of

          (A) cash or Cash Equivalents or

          (B) a controlling interest or a joint venture interest (to the extent
     otherwise permitted by the Indenture) in a business engaged in a Permitted
     Business or long-term property or assets that are used or useful in a
     Permitted Business;

provided that the amount of (x) any liabilities (as shown on the Company's or
such Restricted Subsidiary's most recent balance sheet) of the Company or any
Restricted Subsidiary (other than contingent liabilities and liabilities that
are by their terms subordinated to the Notes or any guarantee thereof) that are
assumed by the transferee of any such assets pursuant to a customary novation
agreement that releases the Company or such Restricted Subsidiary from further
liability and (y) any securities, notes or other obligations received by the
Company or any such Restricted Subsidiary from such transferee that are promptly
converted by the

                                       63
<PAGE>

Company or such Restricted Subsidiary into cash (to the extent of the cash
received), shall be deemed to be cash for purposes of this provision.

     (b)  Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

     (i)  to permanently repay Senior Indebtedness (and to correspondingly
reduce commitments with respect thereto in the case of revolving borrowings) of
the Company or a Subsidiary Guarantor or Indebtedness (and to correspondingly
reduce commitments with respect thereto in the case of revolving borrowings) of
any Restricted Subsidiary that is not a Subsidiary Guarantor; provided that, so
long as the provisions of Section 4.12 are in effect, only repayment of Senior
Indebtedness incurred under the Existing Credit Facility (but not any
refinancing thereof other than a credit facility with commercial banks and other
lenders) or consisting of the 9.9% Debentures due 2000 of ARCO Chemical shall
constitute a repayment of Indebtedness permitted pursuant to this clause (i); or

     (ii)   to acquire a controlling interest or a joint venture interest (to
the extent otherwise permitted by the Indentures) in another business or, the
making of a capital expenditure or the acquisition of other long-term assets, in
each case, in a Permitted Business (or enter into a binding commitment for any
such expenditure or acquisition); provided that such binding commitment shall be
treated as a permitted application of Net Proceeds from the date of such
commitment until and only until the earlier of (x) the date on which such
expenditure or acquisition is consummated and (y) the 180th day following the
expiration of the aforementioned 360 day period. If the expenditure or
acquisition contemplated by such binding commitment is not consummated on or
before such 180th day and the Company shall not have applied such Net Proceeds
pursuant to clause (i) above on or before such 180th day, such commitment shall
be deemed not to have been a permitted application of Net Proceeds at any time;

provided that, so long as the provisions of Section 4.12 are in effect, the
Company may not apply Net Proceeds of a Significant Asset Sale pursuant to
clause (ii) above to satisfy its obligations to apply such proceeds pursuant to
this paragraph except to the extent that the provisions of the Existing Credit
Facility (but not any refinancing thereof other than a credit facility with
commercial banks and other lenders) require a mandatory prepayment from such
proceeds but the requisite lenders thereunder have waived such mandatory
prepayment.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce the revolving Indebtedness under the Existing Credit Facility
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the first sentence of this Section 4.09(b) will be
deemed to constitute "Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $25 million, the
Company will be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and, (x) if the
Company is required to do so under the terms of any other Indebtedness ranking
pari passu with such

                                       64
<PAGE>

Notes, such other Indebtedness, and (y) if the Company elects to do so, any
Existing ARCO Chemical Debt, on a pro rata basis with the Notes, that may be
purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase, in accordance
with the procedures set forth herein.

     To the extent that the aggregate amount of Notes (and any other pari passu
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offer is less than the Excess Proceeds, the Company may, subject to the
other terms of the Indenture, use any remaining Excess Proceeds for general
corporate purposes.

     If the aggregate principal amount of Notes surrendered by Holders thereof
in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased on a pro rata basis.

     Upon completion of the offer to purchase made under the Indenture, the
amount of Excess Proceeds shall be reset at zero.

     (d)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with any Asset
Sale Offer.

     Section 4.10. Limitation on Affiliate Transactions.  (a)  The Company will
not, and will not permit any of its Restricted Subsidiaries to, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on an arms-length basis and (ii) the Company delivers
to the Trustee (a) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $10 million, a Board Resolution set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause  (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess
of $25 million, an opinion as to the fairness to the Company or such Restricted
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an investment banking firm of national standing; provided that:

     (i) transactions or payments pursuant to any employment arrangements or
employee, officer or director benefit plans or arrangements entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business;

     (ii) transactions between or among the Company and/or its Restricted
Subsidiaries;

     (iii) any Restricted Payment permitted by Section 4.07 of the type
described in clause (i) or (ii) of the first paragraph thereof;

                                       65
<PAGE>

     (iv) customary loans, advances, fees and compensation paid to, and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any of its Restricted Subsidiaries;

     (v) transactions entered into on an arms-length basis in the ordinary
course of business between the Company or any of its Restricted Subsidiaries and
any Joint Venture;

     (vi) sales (including a sale in exchange for a promissory note of or Equity
Interest in such Accounts Receivable Subsidiary) of accounts receivable and the
provision of billing, collection and other services in connection therewith, in
each case, to an Accounts Receivable Subsidiary in connection with any
Receivables Facility; and

     (vii) transactions pursuant to any contract or agreement in effect on the
date of the Indenture as the same may be amended, modified or replaced from time
to time so long as any such contract or agreement as so amended, modified or
replaced is, taken as a whole, no less favorable to the Company and its
Restricted Subsidiaries than the contract or agreement as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution); in each
case, shall not be deemed to be Affiliate Transactions and therefore not subject
to the requirements of clauses (i) and (ii) of the initial sentence above.

     Section 4.11.  Limitation on Liens.  (a) The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien (except Permitted Liens) on any asset
now owned or hereafter acquired, or any income or profits therefrom, unless all
payments due under the Indenture and the  Notes or the Subsidiary Guarantees are
secured on an equal and ratable basis with the obligations so secured (or, if
such obligations are subordinated by their terms to the  Notes or the
Subsidiary Guarantees, prior to the obligations so secured) until such time as
such obligations are no longer so secured.

     (b)  The Company and its Subsidiaries shall also comply with the provisions
of Section 4.12(a) until such provisions cease to be in effect pursuant to
Section 4.12(b).

     Section 4.12.  Equal and Ratable Liens.  (a) To the extent the Company or
any Subsidiary of the Company grants a Lien upon any of its property or assets
to secure the Existing Credit Facility Obligations, the Company or such
Subsidiary, as the case may be, shall, contemporaneously with the granting of
such Lien, secure the Indenture Obligations equally and ratably with the
Existing Credit Facility Obligations secured by such Lien.

     (b)  Notwithstanding the foregoing, from and after the date when all Liens
granted in favor of the holders of Existing Credit Facility Obligations are
released (and are not concurrently replaced with any new Liens on any asset of
the Company or any of its Restricted Subsidiaries securing Existing Credit
Facility Obligations), the provisions of this Section 4.12 will no longer apply.
The provisions of Section 4.11 will, however, continue to apply.

     Section 4.13.  No Amendment to Subordination Provisions.  The Company will
not amend, modify or alter the Senior Subordinated Notes Indenture in any way
that would (i) increase the principal of, advance the final maturity date of or
shorten the

                                       66
<PAGE>

Weighted Average Life to Maturity of any Senior Subordinated Notes such that the
final maturity date of the Senior Subordinated Notes is earlier than the 91st
day following the final maturity date of the Notes or (ii) amend the
subordination provisions of the Senior Subordinated Notes Indenture or any of
the defined terms used therein in a manner that would be adverse to the holders
of the Notes.

     Section 4.14. Repurchase of Notes upon a Change in Control. (a) Upon the
occurrence of a Change of Control, each Holder will have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to the offer described below
(the "Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control (the "Change of Control Payment Date"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's
request the Trustee will mail, a notice to each Holder offering to repurchase
the Notes held by such Holder pursuant to the procedures specified in such
notice.

     (b)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
applicable Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered, and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officer's
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company.

     The Paying Agent will promptly mail to each Holder of Notes so tendered the
Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such Note will be in a principal amount
of $1,000 or an integral multiple thereof.

     (d)  The Company 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 at
the same or a higher purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     Section 4.15.  Limitation on Sale and Leaseback Transactions.  The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any Sale and Leaseback Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Leaseback Transaction if: (a) the Company
or such Restricted

                                       67
<PAGE>

Subsidiary, as the case may be, could have (i) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such Sale and Leaseback
Transaction pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.06(a) (whether or not such covenant has ceased to be otherwise in
effect pursuant to Section 4.18) and (ii) incurred a Lien to secure such
Indebtedness pursuant to Section 4.11 without securing the Notes; and (b) the
gross cash proceeds of such Sale and Leaseback Transaction are at least equal to
the fair market value (as conclusively determined by the Board of Directors) of
the property that is the subject of such Sale and Leaseback Transaction.

     Section 4.16.  Limitation on Line of Business.  The Company will not, and
will not permit any of its Restricted Subsidiaries to, engage in any business
other than Permitted Businesses, except to such extent as would not be material
to the Company and its Subsidiaries taken as a whole.

     Section 4.17.  Limitation on Accounts Receivable Facilities.  The Company
may, and any of its Restricted Subsidiaries may, sell (including a sale in
exchange for a promissory note of or Equity Interest in such Accounts Receivable
Subsidiary) at any time and from time to time, accounts receivable to any
Accounts Receivable Subsidiary; provided that the aggregate consideration
received in each such sale is at least equal to the aggregate fair market value
of the receivables sold.

     Section 4.18.  Limited Applicability of Covenants when Notes are rated
Investment-Grade. Notwithstanding the foregoing, the Company's and its
Restricted Subsidiaries' obligations to comply with the provisions of Sections
4.06, 4.07, 4.08, 4.09, 4.10, 4.16, 4.17 and 4.22 will terminate and cease to
have any further effect from and after the first date when the Notes are rated
Investment Grade.

     Section 4.19.  Existence.  Subject to Articles 4 and 5 of this Indenture,
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with the respective organizational
documents of the Company and each such Subsidiary and the rights (whether
pursuant to charter, partnership certificate, agreement, statute or otherwise),
material licenses and franchises of the Company and each such Subsidiary;
provided that the Company shall not be required by this Section 4.19 to preserve
any such right, license or franchise, or the existence of any Restricted
Subsidiary, if the Company shall determine that the maintenance or preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries taken as a whole.

     Section 4.20.  Payment of Taxes and Other Claims.  The Company will pay or
discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (a) all material taxes, assessments and governmental charges levied
or imposed upon (i) the Company or any such Subsidiary, (ii) the income or
profits of any such Subsidiary which is a corporation or (iii) the property of
the Company or any such Subsidiary and (b) all material lawful claims for labor
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good
                                       68
<PAGE>

faith by appropriate proceedings and for which adequate reserves have been
established in accordance with GAAP.

     Section 4.21.  Maintenance of Properties and Insurance.  The Company will
cause all material assets necessary in the conduct of its business or the
business of any of its Restricted Subsidiaries, to be maintained and kept in
good condition, repair and working order (ordinary wear and tear excepted) and
will cause to be made all necessary repairs, renewals and replacements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided that nothing in this Section 4.21 shall prevent the Company or any such
Subsidiary from discontinuing the use, operation or maintenance of any of such
assets or disposing or abandoning of any of them, if such discontinuance,
disposal or abandonment is, in the judgment of the Company, desirable in the
conduct of the business of the Company or such Subsidiary.

     The Company will maintain, and will cause each of its Restricted
Subsidiaries to maintain (either in the Company's name or in such Subsidiary's
own name) insurance on all their respective properties consistent with the
insurance maintained on the Issue Date or otherwise in at least such amounts
(with no materially greater risk retention) and against at least such risks as
are usually maintained, retained or insured against in the same general area by
companies of established repute owning similar properties in such area and
engaged in the same or a similar business, in either case, to the extent
available to the Company and its Restricted Subsidiaries on commercially
reasonable terms.

     Section 4.22.  Limitation on Issuance of Guarantees by Restricted
Subsidiaries. (a) The Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee or secure the
payment of any other Indebtedness of  the Company or any of its Restricted
Subsidiaries (except Indebtedness of such Restricted Subsidiary or a Restricted
Subsidiary of such Restricted Subsidiary) unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture in the form of
Exhibit B hereto providing for the Guarantee of the payment of the Notes by such
Restricted Subsidiary and shall deliver an Opinion of Counsel to the Trustee
pursuant to paragraph (c) below; provided that this paragraph shall not be
applicable to (x) any Guarantee of any Restricted Subsidiary that existed at the
time such Person became a Restricted Subsidiary and was not incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary, (y) Guarantees of Indebtedness of a Restricted Subsidiary that is a
Foreign Subsidiary by a Restricted Subsidiary that is a Foreign Subsidiary or
(z) the granting of Liens by a Joint Venture Subsidiary to secure Indebtedness
under the Existing Credit Facility and the Senior Secured Notes. If the Notes
are (A) pari passu with the Guaranteed Indebtedness, then the Subsidiary
Guarantee shall be pari passu with, or senior to, the guarantee of such
Guaranteed Indebtedness or (B) senior to the Guaranteed Indebtedness, then the
Subsidiary Guarantee shall be senior to the guarantee of such Guaranteed
Indebtedness at least to the extent that the Notes are senior to such Guaranteed
Indebtedness.

     (b)  Notwithstanding the foregoing, each Subsidiary Guarantee by a
Restricted Subsidiary shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all the Company's and each Restricted Subsidiary's
Capital Stock in such Restricted Subsidiary

                                       69
<PAGE>

(which sale, exchange or transfer is not prohibited by the Indenture) as
provided in Section 5.03(b), (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee (or, in the case of
the Subsidiary Guarantees of Lyondell Chemical Worldwide, Inc. and Lyondell
Chemical Nederland, Ltd. issued on the Issue Date, the release or discharge of
its Guarantee of Indebtedness under the Existing Credit Facility), except a
discharge or release by or as a result of payment under such Guarantee, and
(iii) the designation of such Restricted Subsidiary as an Unrestricted
Subsidiary in accordance with the terms of the Indenture.

     (c) The Opinion of Counsel described above shall be to the effect that such
supplemental indenture has been duly authorized, executed and delivered by such
Subsidiary and constitutes a valid and binding obligation of such Subsidiary,
enforceable against such Subsidiary in accordance with its terms (subject to
customary exceptions).

     Section 4.23.  Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes that consent, waive or agree to amend such term or provision in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

disposition shall have been made is a corporation organized or existing under
the laws of the United States, any state thereof or the District of Columbia;

     (ii) the corporation formed by or surviving any such consolidation or
merger (if other than the Company) or the corporation to which such sale,

equal to or greater than the Consolidated Net Worth of the Company immediately
preceding the transaction and (B) except with respect to a consolidation or
merger of the Company with or into a Person that has no outstanding
Indebtedness, will, at the time of such transaction and after giving pro forma
effect thereto as if such transaction had occurred at the beginning of the
applicable four-quarter period, be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set
forth in Section 4.06(a).  The foregoing shall not prohibit the merger or
consolidation of a Wholly Owned Restricted Subsidiary with the Company; provided

another Person.

Section 5.02(b), upon any consolidation or merger, or any sale, assignment,
transfer, conveyance or other disposition of all or substantially all the assets
of the Company in accordance with Section  5.01 hereof, the successor
corporation formed by such consolidation or into or with which the Company is
merged or to which such sale, assignment, transfer, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition, the provisions of this Indenture referring to
the "Company" shall refer instead to the successor corporation), and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein,
and the predecessor Company shall be released from all its obligations hereunder
and under the Notes.

     (b)  The sale, assignment, transfer, lease, conveyance or other disposition
by the Company of all or substantially all its property or assets taken as a
whole to one or more of the Company's Subsidiaries shall not relieve the Company
from its obligations under the Indenture and the Notes.

     Section 5.03. Consolidation, Merger or Sale of Assets by a Subsidiary
Guarantor.  (a) No Subsidiary Guarantor may consolidate with or merge with or
into (whether or not such Subsidiary Guarantor is the surviving Person), another
corporation, Person or entity whether or not affiliated with such Subsidiary
Guarantor unless:

     (i)  subject to the provisions of Section 5.03(b) below, the Person formed
by or surviving any such consolidation or merger (if other than the Company or
such Subsidiary Guarantor) assumes all the obligations of such Subsidiary
Guarantor, pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Trustee, under the Notes;

                                       71
<PAGE>

pro forma effect thereto as if such transaction had occurred at the beginning of
the applicable four-quarter period, (A) have a Consolidated Net Worth
immediately after the transaction equal to or greater than the Consolidated Net

<PAGE>

     (i)  except as permitted by the Indenture, any Subsidiary Guarantee issued
hereunder shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall deny or disaffirm its obligations under the Subsidiary
Guarantees issued thereunder; or

the Liens purported to be created thereby, or any of the Security Documents is

writing that it has any further liability under any Security Document or gives
written notice to such effect (in each case other than in accordance with the
terms of this Indenture (including Section 14.01(b)) or the terms of the
Existing Credit Facility or the Security Documents (including the cessation of
effectiveness of any Security Document in connection with a release of all
collateral covered thereby in accordance with the terms of this Indenture, the
Existing Credit Facility and such Security Document) or unless waived by the
requisite lenders under the Existing Credit Facility if, after the waiver, the
Company is in compliance with Section 4.12; provided that if a failure of the
sort described in this clause (j) is susceptible of cure, no Event of Default
shall arise under this clause (j) with respect thereto until 30 days after
notice of such failure shall have been given to the Company by the Trustee or
Holders of at least 25% in principal amount of the then outstanding Notes issued
under the Indenture.

     Section 6.02.  Acceleration.   If an Event of Default (other than an Event
of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Subsidiary Guarantor) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then Outstanding, by written notice to the Company
(and to the Trustee if such notice is given by the Holders (the "Acceleration
Notice")), may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued but unpaid interest and
Liquidated Damages, if any, on all the Notes to be due and payable.  Upon a
declaration of acceleration, such principal, premium, if any, and accrued
interest and Liquidated Damages, if any, shall be immediately due and payable.
If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs
with respect to the Company or any Subsidiary Guarantor, the principal of,
premium, if any, accrued interest and Liquidated Damages, if any, on the Notes
then Outstanding shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

     Section 6.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest and Liquidated Damages on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  All remedies are cumulative
to the extent permitted by law.

                                       74
<PAGE>

     Section 6.04.  Waiver of Past Defaults.  The Holders of at least a majority
in principal amount of the outstanding Notes, by written notice to the Company
and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences under the Notes, if (i) all
existing Events of Default, other than the nonpayment of the principal of and
premium, if any, and interest and Liquidated Damages, if any, on such Notes that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     Section 6.05.  Control by Majority.  The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from the
Holders.

     Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with
respect to this Indenture or the Notes unless:

     (a)  the Holder gives the Trustee written notice of a continuing Event of
Default;

     (b)  the Holders of at least 25% in aggregate principal amount of
Outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c)  such Holder or Holders offer the Trustee security or indemnity
satisfactory to it against any loss, liability or expense;

     (d)  the Trustee does not comply with the request within 60 days after
receipt thereof and the offer of security or indemnity; and

     (e)  during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes do not give the Trustee a
direction inconsistent with the request.

     Section 6.07.  Rights of Holders to Receive Payment.  Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, interest and Liquidated Damages, if any, on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

                                       75
<PAGE>

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest and Liquidated Damages, if any,
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and Liquidated Damages, if any, and such further amount
as shall be sufficient to cover amounts due the Trustee under Section 7.08,
including the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     Section 6.09.  Trustee May File Proofs of Claim.  The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section  7.08.  To the
extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section  7.08 out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties which the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

     Section 6.10.  Priorities.  If the Trustee collects any money pursuant to
this Article or receives any money from the Collateral Agent as the distribution
of proceeds received upon realization of any Collateral, it shall pay out the
money in the following order:

     First:  to the Trustee, its agents and attorneys for amounts due under
Section  7.08, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

     Second:  to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, interest and Liquidated Damages, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Notes for principal, premium, if any, interest and Liquidated Damages,
respectively; and

                                       76
<PAGE>

     Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section  6.10 upon five Business Days prior notice to
the Company.

     Section 6.11.  Undertaking for Costs.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section  6.06, or a suit by
Holders of more than 10% in aggregate principal amount of the then Outstanding
Notes.

     Section 6.12.  Restoration of Rights and Remedies.  If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture or any Note and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case the Company, any other obligor upon the Notes, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

     Section 6.13.  Rights and Remedies Cumulative.  No right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 6.14.  Waiver of Stay, Extension or Usury Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time hereafter in force, that would prohibit
or forgive the Company from paying all or any portion of the principal of (or
premium, if any), interest or Liquidated Damages, if any, on the Notes
contemplated herein or in the Notes or that may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenant that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy
of mathematical calculations or other facts stated therein).

     (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

     (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph does not
limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is

Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of Sections 7.01
and 7.03.

any, on, any Note, the Trustee may withhold such notice if and so long as the

Trustee of a notice or a certificate which was in fact received), unless the
Trustee shall receive from the Company or a Holder a notice stating that the
same has occurred and is continuing, and specifying the same, and in the absence
of such notice the Trustee may conclusively assume that the same does not exist,
except as aforesaid.

rely upon the Officer's Certificates of the Company;

     (iv)  the Trustee may consult with counsel of its selection and the written

hereunder.

     Section 7.04.  Not Responsible for Recitals or Issuance of Notes.   The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder and that the
statements made by it in a Statement of Eligibility and Qualification on
Form T-1 supplied to the Company in connection with the registration of any

     Section 7.06.  May Hold Notes.   The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Notes and, subject to

Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

     Section 7.07.  Money Held in Trust.  Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money

services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the TIA, within 90 days the Trustee
shall either eliminate such conflicting interest, apply to the SEC for

under any other indenture between the Company and the Trustee.

all times be one (and only one) Trustee hereunder. The Trustee shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $100,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 7.10
and to the extent permitted by the TIA, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
7.10, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

     Section 7.11.  Resignation and Removal; Appointment of Successor.  (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 7.12.

     (b)  The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by

the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                                       81

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 7.12 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the Trustee being removed may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If at any time:

     (i)  the Trustee shall fail to comply with Section 7.09 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
for at least six months, or

     (ii)  the Trustee shall cease to be eligible under Section 7.10 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

     (iii)  the Trustee shall become incapable of acting or shall be adjudged
bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B)
subject to Section 6.11, any Holder who has been a bona fide Holder for at least
six months may, on behalf of itself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee or Trustees.

     (d)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor Trustee and shall comply with the applicable
requirements of Section 7.12. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 7.12,
become the successor Trustee and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner required by
Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide
Holder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     (e)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.10. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

     Section 7.12.  Acceptance of Appointment by Successor.  (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

     (b)  Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to above.

     (c)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

     Section 7.13.  Merger, Conversion, Consolidation or Succession to Business.
(a) Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

     Section 7.14.  Preferential Collection of Claims Against the Company.  (a)
If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Notes), the Trustee shall be subject to the provisions of
the TIA regarding the collection of claims against the Company (or any such
other obligor).

     Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Company to authenticate the Notes. Any
such appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer, a copy of which instrument shall be promptly furnished to
the Company. Unless limited by the terms of such appointment, an Authenticating
Agent may authenticate Notes whenever the Trustee may do so. Each reference in
this Indenture to authentication (or execution of a certificate of
authentication) by the Trustee includes authentication (or execution of a
certificate of authentication) by such Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

<PAGE>

     (b)  Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not (with respect to any Notes held by a non-
consenting Holder):

     (i)  change the Stated Maturity of the principal of, or any installment of
interest on, any Note,

     (ii)  reduce the principal amount of or premium, if any, or interest or

     (iv) change the place or currency of payment of principal of or premium, if

whose Holders is necessary to modify or amend the Indenture,

     (x)  release any Subsidiary Guarantor from any of its obligations under its

provisions of the Indenture, or amend or modify any provision relating to such
release, or

     (xi)  directly or indirectly release the Liens created by the Security

                                       86
<PAGE>

     (c)  It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

     (d)  After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by the
Company and that such amendment, supplement or waiver is a valid and binding
agreement of the Company, enforceable against it in accordance with its terms
(subject to customary exceptions).

     Section 9.04.  Revocation and Effect of Consents.  (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of that Note or any
Note that evidences all or any part of the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. Subject to the
following paragraph of this Section 9.04, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note by notice to the Trustee or the
Company received by the Trustee or the Company, as the case may be, before the
date on which the Trustee receives an Officer's Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver as set forth in Section 1.08.

     (b)  After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (i)
through (viii) of Section 9.02(b). In that case, the amendment, supplement or
waiver shall bind each Holder of a Note who has consented to it and every
subsequent Holder of such Note or any Note that evidences all or any part of the
same debt as the consenting Holder's Note.

     Section 9.05.  Conformity with TIA.  (a) Every amendment or supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the TIA as then in effect.

     Section 9.06.  Notation on or Exchange of Notes.  (a)  If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Company and in accordance with the specific direction of the Company)
request the

                                       87
<PAGE>

Holder to deliver its Note to the Trustee. The Trustee shall (if required by the
Company and in accordance with the specific written direction of the Company)
place an appropriate notation on the Note about the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
amendment, supplement or waiver.

for in this Section 11.01 relating to the satisfaction and discharge of this
Indenture have been complied with; provided that any such counsel may rely on
any Officer's Certificate as to matters of fact (including as to compliance with
the foregoing clauses (i), (ii) and (iii)).

     (b)  Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.08 and, if money shall
have been deposited with the Trustee pursuant to clause (ii) of Section
11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

     Section 11.02. Application of Trust Money. Subject to the provisions of the
last paragraph of Section 4.03, all money deposited with the Trustee pursuant to
Section 11.01 shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal
(and premium, if any) and interest and Liquidated Damages on the Notes; but such
money need not be segregated from other funds except to the extent required by
law.



                                  ARTICLE 12

                      Defeasance and Covenant Defeasance

     Section 12.01.  Option of the Company to Effect Defeasance or Covenant
Defeasance.  The Company may at its option by a Board Resolution, at any time,
elect to have either Section 12.02 or Section 12.03 applied to the Outstanding
Notes upon compliance with the conditions set forth below in this Article 12.

     Section 12.02.  Legal Defeasance and Discharge.  Upon the exercise by the
Company under Section 12.01 of the option applicable to this Section 12.02, the
Company shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this
Section 12.02, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of,

                                       92
<PAGE>

premium, if any, and interest and Liquidated Damages on such Notes when such
payments are due, (ii) the obligations of the Company with respect to such Notes
under Sections 1.06, 2.03, 3.03, 3.04, 3.05, 3.06, 3.13, 3.14, 4.01, 4.02, 4.03
and 12.05 hereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Company in connection therewith
and with this Article 12. Subject to compliance with this Article 12, the
Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 hereof with respect to the
Notes.

     Section 12.03. Covenant Defeasance. Upon the exercise by the Company under
Section 12.01 of the option applicable to this Section 12.03, the Company shall
be released from its obligations under the covenants contained in Sections 4.06
through Section 4.18, Section 4.22, Article 14 and clause (iv) of Section
5.01(a) hereof with respect to the Outstanding Notes and no Default under
Section 6.01(e), (f) and (j) shall thereafter constitute a Default or Event of
Default on the date which is the 123rd day after the deposit referred to in
Section 12.04(a); provided that all of the conditions set forth below are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter
be deemed not Outstanding for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed Outstanding for
all other purposes hereunder. For this purpose, such Covenant Defeasance means
that, with respect to the Outstanding Notes, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 6.01(c) or (d), but, except as specified above, the remainder of
this Indenture and such Notes shall be unaffected thereby.

     Section 12.04.  Conditions to Legal or Covenant Defeasance.  The following
shall be the conditions to application of either Section  12.02 or Section
12.03 to the Outstanding Notes:

     (a)  the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay (i) the principal of, premium, if any, and accrued interest and
Liquidated Damages, if any, on the Notes when such payments are due in
accordance with the terms of this Indenture and the Notes or (ii) in the case of
Legal Defeasance, accrued interest and Liquidated Damages, if any, on the Notes
through a scheduled redemption date and the principal of, and premium on the
Notes on such redemption date; provided that, at the time of deposit, the
Company irrevocably authorize the Trustee to issue a timely notice of redemption
and to take such other steps reasonably requested by the Trustee to ensure that
such redemption will be effectuated;

                                       93
<PAGE>

     (b)  in the case of an election under Section 12.02, the Company has
delivered to the Trustee (i) either (x) 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 the exercise by the Company of its option under this Article 12
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of this Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that, as a result of the creation of
the defeasance trust, the Company will not be required to register under the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund will not be subject to the effect of Section 547 of the
United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor
Law or any comparable provision of applicable law;

     (c)  in the case of an election under Section 12.03, the delivery by the
Company to the Trustee of (i) an Opinion of Counsel to the effect that, among
other things, the 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 amount 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 (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, the Company will not be required to
register under the Investment Company Act of 1940 and after the passage of 123
days following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or any comparable provision of applicable law;

     (d)  immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound;

     (e)  if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to the
effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge;

     (f)  the Company shall have delivered to the Trustee Officer's Certificates
stating that the deposit made by the Company pursuant to its election under
Sections 12.02 or 12.03 was not made by the Company with the intent of
preferring the Holders over the other creditors of the Company with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others; and

     (g)  the Company shall have delivered to the Trustee Officer's Certificates
and an Opinion of Counsel, each stating that all conditions precedent provided
for relating to

                                       94
<PAGE>

either the Legal Defeasance under Section 12.02 or the Covenant Defeasance under
Section 12.03 (as the case may be) have been complied with as contemplated by
this Section 12.04.

     Section 12.05.  Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions.  Subject to Section  12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section  12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section  12.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

     Anything in this Article 12 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or U.S. Government Obligations held by it as provided in
Section  12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
12.04(a) hereof), are in excess of the amount thereof which would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

     Section 12.06.  Repayment to Company.  Any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest and Liquidated Damages on any
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest and Liquidated Damages has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause
to be published once, in The New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 12.07.  Reinstatement.  If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section  12.02
or 12.03, as the case may be, by reason of any order or judgment of any court or
governmental

                                       95
<PAGE>

authority enjoining, restraining or otherwise prohibiting such application, then
the obligations of the Company under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
12.02 or 12.03 until such time as the Trustee or Paying Agent is permitted to
apply all such amounts in accordance with Section 12.02 or 12.03 hereof, as the
case may be; provided, however, that, if the Company makes any payment of
principal of, premium, if any, or interest and Liquidated Damages on any Note
following the reinstatement of its Obligations, the Company shall be subrogated
to the rights of the Holder of such Note to receive such payment from the
amounts held by the Trustee or Paying Agent.


                                  ARTICLE 13

                             Subsidiary Guarantees

     Section 13.01.  The Guarantees.  (a) Subject to the provisions of this
Article 13, each Subsidiary Guarantor hereby irrevocably and unconditionally
guarantees, jointly and severally, the full and punctual payment (whether at
Stated Maturity, upon acceleration, optional redemption, upon repurchase
following a Change of Control Offer or an Asset Sale Offer or otherwise) of the
principal of and premium, if any, and interest and Liquidated Damages, if any,
on, and all other amounts payable under, each Note provided for under this
Indenture, and the full and punctual payment of all other amounts payable by the
Company under this Indenture.  Upon failure by the Company to pay punctually any
such amount, each Subsidiary Guarantor shall forthwith on demand pay the amount
not so paid at the place and in the manner specified in this Indenture.

     Section 13.02.  Guarantee Unconditional.  The obligations of the Subsidiary
Guarantors hereunder shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall, to the fullest extent permitted by law,
not be released, discharged or otherwise affected by:

     (a)  any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Company under this Indenture or any Note, by
operation of law or otherwise;

     (b)  any modification or amendment of or supplement to this Indenture or
any Note; provided that any such modification which increases the obligations of
each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary
Guarantor without its consent;

     (c)  any release, impairment, non-perfection or invalidity of any direct or
indirect security for any obligation of the Company or any Subsidiary Guarantor
hereunder;

     (d)  any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Company or its assets or any resulting release or
discharge of any obligation of the Company contained in this Indenture or any
Note;

                                       96
<PAGE>

     (e)  the existence of any claim, set-off or other rights which the
Subsidiary Guarantors may have at any time against the Company, the Trustee or
any other Person, whether in connection with this Indenture or any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

     (f)  any invalidity or unenforceability relating to or against the Company
for any reason of this Indenture or any Note, or any provision of applicable law
or regulation purporting to prohibit the payment by the Company of the principal
of or interest and Liquidated Damages on any Note or any other amount payable by
the Company under this Indenture; or

     (g)  any other act or omission to act or delay of any kind by the Company,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Subsidiary Guarantor's obligations hereunder.

     Section 13.03.  Discharge; Reinstatement.  The Subsidiary Guarantors'
obligations hereunder shall remain in full force and effect until the principal
of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
and all other amounts payable by the Company under this Indenture shall have
been paid in full.  If at any time any payment of the principal of, premium, if
any, or interest and Liquidated Damages, if any, on any Note or any other amount
payable by the Company under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, the Subsidiary Guarantors' obligations hereunder with
respect to such payment shall be reinstated as though such payment had been due
but not made at such time.

     Section 13.04.  Waiver by the Subsidiary Guarantors.  The Subsidiary
Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and
any notice not provided for herein, as well as any requirement that at any time
any action be taken by any Person against the Company or any other Person.

     Section 13.05.  Subrogation and Contribution.  Upon making any payment with
respect to any obligation of the Company under this Article 13, the Subsidiary
Guarantor making such payment shall be subrogated to the rights of the payee
against the Company with respect to such obligation; provided that such
Subsidiary Guarantor shall not enforce either (i) any right to receive payment
by way of subrogation against the Company or against any direct or indirect
security for such obligation, or any other right to be reimbursed, indemnified
or exonerated by or for the account of the Company in respect thereof or (ii)
any right to receive payment, in the nature of contribution or for any other
reason, from any other Subsidiary Guarantor with respect to such payment, in
each case so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

     Section 13.06.  Stay of Acceleration.  If acceleration of the time for
payment of any amount payable by the Company under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise

                                       97
<PAGE>

subject to acceleration under the terms of this Indenture shall nonetheless be
payable by the Subsidiary Guarantors hereunder forthwith on demand by the
Trustee or the Holders.

     Section 13.07.  Limits of Guarantees.  Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law.  To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the maximum
amount that would not render such Subsidiary Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law.

     Section 13.08.  Execution and Delivery of Note Guarantee.  To evidence its
Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
hereby agrees that this Indenture (or a supplemental indenture in the form of
Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by
one of its Officers.

     The signature of an Officer of a Subsidiary Guarantor on the Indenture
shall bind such Subsidiary Guarantor, notwithstanding that such individual has
ceased to hold such office prior to the authentication and delivery of any Note
or did not hold such office at the date of such Note.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Indenture on behalf of the Subsidiary Guarantors.


                                  ARTICLE 14

                             Security Arrangements

     Section 14.01.  Security.  (a) In order to secure the Indenture Obligations
equally and ratably with the Existing Credit Facility Obligations and, with
respect to certain of the Collateral, the Existing ARCO Chemical Debt, the
Company will, and will cause each of its Restricted Subsidiaries named in any
Existing Security Document as a party thereto, to execute and deliver to the
Collateral Agent prior to the Issue Date each Existing Security Document to
which it is a party.  The Company and its Restricted Subsidiaries shall comply
with all covenants and agreements contained in the Security Documents the
failure to comply with which would have a material and adverse effect on the
Liens purported to be created thereby, unless such failure to comply is waived
by the requisite lenders under the Existing Credit Facility if, after that
waiver, the Company is in compliance with Section 4.12.

     (b)  The Trustee and each holder of each Note by its acceptance of that
Note acknowledges and agrees that:

                                       98
<PAGE>

     (i)  this Indenture, as originally executed and delivered by the parties
hereto, does not create any Lien on any property or securities which secures the
Indenture Obligations or this Indenture;

     (ii)  the Existing Security Documents, when executed and delivered by the
parties thereto, will comply with the provisions of Section 4.12;

     (iii)  the Existing Security Documents provide, and any Security Document
that becomes effective after the Issue Date, may provide, that the Liens created
thereby or thereunder automatically will be released and extinguished with
respect to any property or security that is transferred or otherwise disposed of
in accordance with the terms of the Existing Credit Facility, including any
property or security that is the subject of a Major Asset Sale and is
transferred to a Subject Asset Transferee;

     (iv) without the necessity of any consent of or notice to the Trustee or
any holder of Indenture Obligations, the Company and the Collateral Agent may
amend, modify, supplement or terminate any Security Document as long as the
Company remains in compliance with Section 4.12;

     (v)  as among the Trustee and the holders of Indenture Obligations and the
lenders under the Existing Credit Facility and the Collateral Agent, those
lenders and the Collateral Agent will have the sole ability to control and
obtain remedies with respect to all Collateral (including on sale or liquidation
of any Collateral after acceleration of the Notes, the Existing Credit Facility
Obligations or the Existing ARCO Chemical Debt) without the necessity of any
consent of or notice to the Trustee or any such holder;

     (vi) any or all Liens granted under the Security Documents for the benefit
of the Holders will be automatically released, without the necessity of any
consent of the Trustee or any Holders, upon a release of such Lien or Liens
pursuant to the terms of the Security Documents and the Existing Credit Facility
or if such release is approved by the requisite lenders under the Existing
Credit Facility.

     (vii)  the relative rights of the holders of Indenture Obligations and the
holders of Indebtedness or other obligations secured by Liens on the Collateral
are governed by, and are subject to the terms and conditions of, the Security
Documents and not this Indenture; and

     (viii) without the necessity of any consent of or notice to the Trustee or
any holder of Indenture Obligations, the Company may, on behalf of itself or any
of its Restricted Subsidiaries, request and instruct the Collateral Agent to, on
behalf of each secured party under the Security Documents, (A) execute and
deliver to the Company, for the benefit of any Person, such release documents as
the Company may reasonably request, of all liens and security interests held by
the Collateral Agent in such assets, and such Person shall be entitled to rely
conclusively on such release document, and (B) deliver any such assets in the
possession of the Collateral Agent to the Company.

                                       99
<PAGE>

     Section 14.02. Notice of Payment, Discharge or Defeasance. The Trustee and
each Holder, by its acceptance of a Note, agree that upon the payment in full or
discharge pursuant to Article 11 of the Indenture Obligations, the Trustee shall
without notice to or consent of any Holder, upon the written request of the
Company, certify to the Collateral Agent, in writing, that the Indenture
Obligations have been paid in full, or that this Indenture has been discharged
in accordance with Article 11.

        IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, all as of the date first written above.

                           LYONDELL CHEMICAL COMPANY

                9 7/8% Senior Secured Note, Series B, due 2007


     (1) Principal and Interest. The Company agrees to pay the principal of this
Note on May 1, 2007.

     The Company agrees to pay interest on the principal amount of this Note on
each Interest Payment Date, as set forth below, at the rate of 9 7/8% per annum.

     Interest will be payable semi-annually (to the Holders of record of the
Notes (or any predecessor Notes) at the close of business on the Regular Record
Date immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing November 1, 1999.

     [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated May 17, 1999, among the Company, the Subsidiary
Guarantors party thereto and the Initial Purchasers named therein (the
"Registration Rights Agreement"). In the event that (i) the Company or the
Subsidiary Guarantors fail to file an Exchange Offer Registration Statement with
the SEC on or prior to the 90th day after the Issue Date, (ii) if the Exchange
Offer Registration Statement is not declared effective by the SEC on or prior to
the 210th day after the Issue Date, (iii) if the Exchange Offer is not
consummated on or before the 30th business day after the Exchange Offer
Registration Statement is declared effective, (iv) the Company and the
Subsidiary Guarantors are obligated to file the Shelf Registration Statement and
fail to file the Shelf Registration Statement with the SEC on or prior to the
30th day after such filing obligation arises, (v) the Company and the Subsidiary
Guarantors are obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 60th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Notes during the periods specified
in the Registration Rights Agreement, for such time of non-effectiveness or non-
usability (each, a "Registration Default"), the Company and the Subsidiary
Guarantors agree to pay to the Holder of this Note, if affected thereby,
liquidated damages ("Liquidated Damages") in an amount equal to $0.05 per week
per $1,000 in principal amount of this Note for each week or portion thereof
that the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Notes with respect to each subsequent 90 day period until
all Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.50 per week per $1,000 in principal amount of Notes. The Company
and the Subsidiary Guarantors shall not be required to pay Liquidated Damages
for more than one

                                      A-4
<PAGE>

Registration Default at any given time. Following the cure of all Registration
Defaults, the accrual of Liquidated Damages will cease.]./2/

     Interest on this Note will accrue from the most recent date to which
interest has been paid [on this Note or the Note surrendered in exchange
herefor]/1/ or, if no interest has been paid, from May 17, 1999; provided that,
if there is no existing default in the payment of interest and if this Note is
authenticated between a Regular Record Date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest and Liquidated Damages, to the
extent lawful, at a rate per annum equal to 1% per annum in excess of the rate
of interest applicable to the Notes.

     (2) Method of Payment. The Company will pay interest (except defaulted
interest) on the principal amount of the Notes on each May 1 and November 1 to
the Persons who are Holders (as reflected in the Register at the close of
business on the April 15 and October 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is canceled on registration of
transfer or registration of exchange after such Regular Record Date; provided
that, with respect to the payment of principal, the Company will make payment to
the Holder that surrenders this Note to any Paying Agent on or after May 1,
2007.

     The Company will pay principal, premium, if any, and interest and
Liquidated Damages, if any, in money of the United States that at the time of
payment is legal tender for payment of public and private debts.  Payments
(including principal, premium, if any, and interest and Liquidated Damages, if
any) in respect of the Notes represented by the Global Notes, the Holders of
which have given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Company will make all payments of principal, premium, if any, and interest
and Liquidated Damages, if any, at the office or agency maintained by the
Company for such purposes in The City of New York or, at the Company's option,
by mailing a check to each such Holder's registered address. If a payment date
is a date other than a Business Day, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

     (3)  Paying Agent and Registrar.  Initially, the Trustee will act as Paying
Agent and Registrar.  The Company may change any Paying Agent or Registrar upon
written notice thereto.  The Company, any Subsidiary or any Affiliate of any of
them may act as Paying Agent, Registrar or co-registrar.

     (4)  Indenture; Limitations.  The Company issued the Notes under an
Indenture dated as of May 17, 1999 (the "Indenture"), among the Company, the
Subsidiary


- -------------
/2/  Include only for Initial Note.

                                      A-5
<PAGE>

Guarantors and The Bank of New York, as trustee (the "Trustee"). Capitalized
terms herein are used as defined in the Indenture unless otherwise indicated.
The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 (the "TIA").
The Notes are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of all such terms. To the extent permitted
by applicable law, in the event of any inconsistency between the terms of this
Note and the terms of the Indenture, the terms of the Indenture shall control.

     The Notes are secured senior obligations of the Company. The Indenture
limits the initial aggregate principal amount of the Notes to $1,000,000,000 but
permits the issuance of Additional Notes subject to compliance with the
covenants contained in the Indenture and except as may be limited by applicable
law; provided that the aggregate principal amount of Senior Secured Notes
outstanding at any time shall not exceed $1.9 billion.

     (5) Optional Redemption. The Notes may be redeemed at the option of the
Company, in whole or in part, at any time and from time to time, on or after May
1, 2004, at the following Redemption Prices (expressed in percentages of
principal amount on the relevant Redemption Date), plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date, if redeemed
during the 12-month period commencing of each of the years set forth below:

         YEAR            REDEMPTION PRICE
         ----            -----------------
2004                              104.938%
2005                              102.469%
2006 and thereafter               100.000%


  If less than all the Notes are to be redeemed at any time, selection of Notes
for redemption will be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a pro rata basis, by lot or by
such method as the Trustee shall deem fair and appropriate; provided that no
Notes of $1,000 or less shall be redeemed in part.

  Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder of Notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed.  A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if any, cease to accrue on Notes or portions of them called
for redemption.

  (6)  Repurchase upon a Change in Control and Sale of Assets.  Upon the
occurrence of (a) a Change in Control, each Holder shall have the right to
require that the Company repurchase such Holder's Notes at a purchase price in
cash equal to 101% of the

                                      A-6
<PAGE>

principal amount thereof on the date of purchase, plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase and (b) an
Asset Sale, the Company may be obligated to make an offer to purchase on a pro
rata basis from the Holders the Notes with the Excess Proceeds of such Asset
Sales at a purchase price equal to 100% of the principal amount of such Notes
plus accrued interest and Liquidated Damages, if any, to the date of purchase.

  (7)  Denominations; Transfer; Exchange.  The Notes are in fully registered
form without coupons, in denominations of $1,000 and any integral multiples of
$1,000. A Holder may register the transfer or exchange of Notes in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture.

  (8)  Persons Deemed Owners.  A Holder may be treated as the owner of a Note
for all purposes.

  (9)  Unclaimed Money.  If money for the payment of principal, premium, if any,
or interest and Liquidated Damages, if any, remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the Company at its
written request.  After that, Holders entitled to the money must look to the
Company for payment, unless an abandoned property law designates another Person,
and all liability of the Trustee and such Paying Agent with respect to such
money shall cease.

  (10) Discharge Prior to Redemption or Maturity.  If the Company irrevocably
deposits, or causes to be deposited, with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of and  premium, if
any, and accrued interest and Liquidated Damages on the Notes (a) to redemption
or maturity, the Company will be discharged from the Indenture and the Notes,
except in certain circumstances for certain sections thereof, and (b) to
redemption or maturity, the Company will be discharged from certain covenants
set forth in the Indenture.

  (11) Amendment; Supplement; Waiver.  Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
Outstanding, and any existing Default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding.  Without notice to or the consent of any
Holder, the parties thereto may amend the Indenture or the Notes to the extent
set forth in the Indenture.

  (12) Restrictive Covenants.  The Indenture contains certain covenants,
including, without limitation, covenants with respect to the following matters:
(i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted
Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with
Affiliates; (vi) Liens; (vii) No Amendments to Subordination Provisions; (viii)
repurchase of Notes upon a Change in Control; (ix) Sale and Leaseback
Transactions; (x) Subsidiary Guarantees; and (xi) consolidation, merger and sale
of assets.  Within 120 days after the end of each fiscal year, the Company must
report to the Trustee on compliance with such limitations.

                                      A-7
<PAGE>

  (13) Successor Persons.  When a successor person or other entity (other than a
Subsidiary of the Company) assumes all the obligations of its predecessor under
the Notes and the Indenture, the predecessor person will be released from those
obligations.

  (14) Remedies for Events of Default.  If an Event of Default (other than an
Event of Default specified in Section 6.01(g) or (h) of the Indenture that
occurs with respect to the Company or a Subsidiary Guarantor) occurs and is
continuing under this Indenture, then in every such case the Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding Notes,
by written notice to the Company (and to the Trustee if such notice is given by
the Holders), may, and the Trustee at the written request of such Holders shall,
declare the principal of, premium, if any, and accrued interest and Liquidated
Damages, if any, on all of the Outstanding Notes to be immediately due and
payable.  Upon a declaration of acceleration, such principal of, premium, if
any, and accrued interest and Liquidated Damages, if any, shall be immediately
due and payable. If an Event of Default specified in  Section 6.01(g) or (h) of
the Indenture occurs with respect to the Company or a Subsidiary Guarantor, the
principal of, premium, if any, and accrued interest and Liquidated Damages, if
any, on the Outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.  The Holders of at least a majority in aggregate principal amount of the
Outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if (1) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes that have become due solely by such declaration of acceleration,
have been cured or waived and (2) the recission would not conflict with any
judgment or decree of a court of competent jurisdiction.

  Holders may not enforce the Indenture, the Notes or the Subsidiary Guarantees
except as provided in the Indenture.  The Trustee may require security or
indemnity satisfactory to it before it enforces the Indenture, the Notes or the
Subsidiary Guarantees. The Holders of at least a majority in aggregate principal
amount of the Notes then Outstanding may direct the Trustee in the exercise of
any trust or power in accordance with the terms of the Indenture.

  (15) Security.  In order to secure the Indenture Obligations, the Company and
certain of its Restricted Subsidiaries have entered into the Security Documents.
The Indenture Obligations shall be secured by Liens on the Collateral in
accordance with the terms and provisions of the Security Documents.  The
Indenture requires that Holders of the Notes be granted a lien equally and
ratably with any lien granted on additional assets to secure the holders of
Existing Credit Facility Obligations subsequent to the Issue Date. Each Holder
of this Note, by accepting the same, agrees that (i) the Existing Security
Documents provide, and any Security Document that becomes effective after the
Issue Date, may provide, that the Liens created thereby or thereunder
automatically will be released and extinguished with respect to any property or
security that is transferred or otherwise disposed of in accordance with the
terms of the Existing Credit Facility, including any property or security that
is the subject of a Major Asset Sale and is transferred to a Subject Asset
Transferee; (ii) without the necessity of any consent of or notice to the
Trustee or any holder of Indenture Obligations, the Company and the Collateral
Agent may amend, modify, supplement or terminate any Security Document as

                                      A-8
<PAGE>

long as the Company remains in compliance with the Indenture; (iii) as among the
Trustee and the holders of Indenture Obligations and the lenders under the
Existing Credit Facility and the Collateral Agent, those lenders and the
Collateral Agent will have the sole ability to control and obtain remedies with
respect to all Collateral (including on sale or liquidation of any Collateral
after acceleration of the Notes, the Existing Credit Facility Obligations or the
Existing ARCO Chemical Debt) without the necessity of any consent of or notice
to the Trustee or any such holder; (iv) any or all Liens granted under the
Security Documents for the benefit of the Holders will be automatically
released, without the necessity of any consent of the Trustee or the Holders,
upon a release of such Lien or Liens pursuant to the terms of the Security
Documents and the Existing Credit Facility or if such release is approved by the
requisite lenders under the Existing Credit Facility; (v) the relative rights of
the holders of Indenture Obligations and the holders of Indebtedness or other
obligations secured by Liens on the Collateral are governed by, and are subject
to the terms and conditions of, the Security Documents and not this Indenture;
and (vi) without the necessity of any consent of or notice to the Trustee or any
holder of Indenture Obligations, the Company may, on behalf of itself or any of
its Restricted Subsidiaries, request and instruct the Collateral Agent to, on
behalf of each secured party under the Security Documents, (A) execute and
deliver to the Company, for the benefit of any Person, such release documents as
the Company may reasonably request, of all liens and security interests held by
the Collateral Agent in such assets, and such Person shall be entitled to rely
conclusively on such release document, and (B) deliver any such assets in the
possession of the Collateral Agent to the Company. From and after the date when
all liens granted in favor of the holders of Existing Credit Facility
Obligations are released, the provisions regarding security described above will
no longer apply.

  (16) Subsidiary Guarantees.  Each Subsidiary Guarantor irrevocably and
unconditionally guarantees, jointly and severally, on a senior basis, the full
and punctual payment (whether at Stated Maturity, upon acceleration, optional
redemption, upon repurchase following a Change of Control Offer or an Asset Sale
Offer or otherwise) of the principal of, premium, if any, and interest and
Liquidated Damages, if any, on, and all other amounts payable under, this Note
provided for under this Indenture, and the full and punctual payment of all
other amounts payable by the Company under the Indenture; provided that,
notwithstanding anything to the contrary herein, the aggregate amount of the
Obligations guaranteed under the Indenture by any Subsidiary Guarantor shall be
limited in amount to the maximum amount that would not render such Subsidiary
Guarantor's obligations subject to avoidance under the applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable
provision of any applicable state law.

  (17) Additional Subsidiary Guarantees.  If  any of the Company's Restricted
Subsidiaries shall Guarantee or secure the payment of any other Indebtedness of
the Company or any of its Restricted Subsidiaries, then, subject to certain
exceptions specified in the Indenture, such Restricted Subsidiary shall become a
Subsidiary Guarantor by executing a supplemental indenture.

  (18) Trustee Dealings with Company.  The Trustee under the Indenture, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may make loans to, accept deposits from, perform services for, and otherwise
deal with, the Company and its Affiliates as if it were not the Trustee.

  (21) Governing Law. This Note shall be governed by and construed in accordance
with the internal laws of the State of New York, without giving effect to any
principles of conflict of laws to the extent that the application of the law of
another jurisdiction is required thereby.

          The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture. Requests may be made to the Company, One

instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Section 1.08.  Acts of Noteholders; Record Dates.   (a)  Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such Holders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee, and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 7.01)
conclusive in favor of the Trustee, the Company and any other obligor upon the
Notes, if made in the manner provided in this Section 1.08.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership or
other entity, on behalf of such corporation or partnership or other entity, such
certificate or affidavit shall also constitute sufficient proof of such Person's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the person executing the same, may also be proved in any
other manner that the Trustee deems sufficient.

                                       30

     (c)  The ownership of Notes shall be proved by the Register.

     (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Note shall bind the Holder of every Note
issued upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done or suffered to be done by the Trustee, the Company or
any other obligor on the Notes in reliance thereon, whether or not notation of
such action is made upon such Note.

     (e)  (i) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in Section
1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date (or their duly designated proxies), and
no other Holders, shall be entitled to take the relevant action, whether or not
such Persons remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Notes on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder in the manner set forth in Section 1.10.

          (ii)  The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to join in the giving or
making of (w) any Notice of Default, (x) any declaration of acceleration
referred to in Section 6.02, (y) any request to institute proceedings referred
to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each
case with respect to Notes. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Notes on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the expense of the Company, shall cause notice of such record date,
the proposed action by Holders and the applicable

                                       31
<PAGE>

Expiration Date to be given to the Company in writing and to each Holder in the
manner set forth in Section 1.10.

          (iii)  With respect to any record date set pursuant to this Section
1.08, the party hereto that sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Company or the
Trustee, whichever such party is not setting a record date pursuant to this
Section 1.08(e) in writing, and to each Holder in the manner set forth in
Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

          (iv)  Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Note may do so with
regard to all or any part of the principal amount of such Note or by one or more
duly appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     Section 1.09.  Notices, Etc., to Trustee and Company.  Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

     (a)  the Trustee by any Holder or by the Company or any other obligor upon
the Notes shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at the Corporate Trust
Office (telephone: (212) 815-6286; facsimile: (212) 815-5915), or at any other
address furnished in writing to the Company by the Trustee, or

     (b)  the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder if in writing and delivered in person or mailed, first-
class postage prepaid, to the Company at One Houston Center, Suite 700, 1221
McKinney, Houston, Texas 77010, Attention: General Counsel (facsimile: (713)
309-2143), with copies to Baker & Botts LLP at 910 Louisiana, Houston, Texas
77002, Attention: Steve Massad, Esq. (facsimile: (713) 229-1522), or at any
other address previously furnished in writing to the Trustee by the Company.

     Section 1.10.  Notices to Holders; Waivers.  Where this Indenture provides
for notice to Holders of any event, such notice shall be deemed to have been
given upon the mailing by first class mail, postage prepaid, of such notices to
Holders at their registered addresses as recorded in the Register, not later
than the latest date, and not earlier than the earliest date, prescribed herein
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.

                                       32
<PAGE>

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail notice of any event as
required by any provision of this Indenture, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably
withheld) shall constitute a sufficient notification for every purpose
hereunder.

     Section 1.11.  Effect of Headings and Table of Contents.  The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 1.12. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its respective successors and assigns,
whether so expressed or not.

     Section 1.13. Separability Clause. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 1.14.  Benefits of Indenture.  Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 1.15.  Governing Law.  THIS INDENTURE, THE NOTES AND THE SUBSIDIARY
GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY.  TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY,
THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY
THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NONEXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THIS INDENTURE OR THE NOTES.

     Section 1.16. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest and Liquidated Damages, if any, or principal and premium (if any)
need not be made on such date, but may be made on the next succeeding Business
Day with the same force and

                                       33
<PAGE>

effect as if made on the Interest Payment Date or Redemption Date, or at the
Stated Maturity.

     Section 1.17.  No Personal Liability of Directors, Officers, Employees,
Incorporators and Stockholders.  No director, officer, employee, incorporator,
shareholder or other holder of Equity Interests of the Company or the Subsidiary
Guarantors, as such, shall have any liability for any obligations of the Company
or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

     Section 1.18.  Exhibits and Schedules.  All exhibits and schedules attached
hereto are by this reference made a part hereof with the same effect as if
herein set forth in full.

     Section 1.19.  Counterparts.  This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

7.15, the Notes may have endorsed thereon, in lieu of the Trustee's certificate
of authentication, an alternative certificate of authentication in the following
form:

     This is one of the Notes referred to in the within-mentioned Indenture.

Registration Rights Agreement or otherwise or (ii) an Initial Note or any
Additional Note is exchanged for an Exchange Note in an Exchange Offer pursuant
to an effective Exchange Offer Registration Statement pursuant to the

shall bear the following legend set forth below (the "Private Placement Legend")
on the face thereof:

<PAGE>

THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY
STATE OR OTHER JURISDICTION, AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS
ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

(1)  REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (As defined in
     Rule 144A under the Securities Act) (A "QIB")

(2)  AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A)
     TO THE COMPANY, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
     QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB TO WHOM
     NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A IN
     A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (C) IN A TRANSACTION
     MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT (IF
     AVAILABLE), (D) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION
     REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL,
     CERTIFICATION AND/OR OTHER INFORMATION ACCEPTABLE TO THE COMPANY AND THE
     TRUSTEE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN
     EACH CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE
     OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND

(3)  AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST
     HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER
ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING.

     (b)  Each Global Note, whether or not an Initial Note or Additional Note,
shall also bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR
THEIR AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME
AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE
TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE

                                       36
<PAGE>

HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE

SECTIONS 3.13 AND 3.14 OF THE INDENTURE.



                                   ARTICLE 3
                                   THE NOTES

     Section 3.01.  Title and Terms.  The aggregate principal amount of Notes
that may be authenticated and delivered and Outstanding under this Indenture is
initially limited to $500,000,000, but may be increased, without limit, subject
to compliance with the covenants contained in Article 4 below and the conditions
set forth in Section 3.03, and except as may be limited by applicable law. The
Initial Notes will be issued in an aggregate principal amount of $500,000,000.
All the Original Notes shall vote and consent together on all matters as one
class, and none of the Original Notes will have the right to vote or consent as
a class separate from one another on any matter. Subject to the covenants
contained in Article 4 below, the Company may issue Additional Notes hereunder.
Additional Notes (including any Exchange Notes issued in exchange therefor)
shall vote (or consent) as a class with the other Notes and otherwise be treated
as Notes for all purposes of this Indenture.

     The Notes shall be known and designated as the "10 7/8% Senior Subordinated
Notes Due 2009" of the Company. The final Stated Maturity of the Notes shall be
May 1, 2009. Interest on the Outstanding principal amount of Notes will accrue,
subject to Section 3.11, at the rate of 10 7/8% per annum and will be payable
semiannually in arrears on May 1 and November 1 in each year, commencing on
November 1, 1999, to Holders of record at the close of business on the
immediately preceding April 15 and October 15, respectively (each such April 15
and October 15, a "Regular Record Date"). Interest on the Original Notes will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid, from May 17, 1999, and interest
on any Additional Notes (and Exchange Notes issued in exchange therefor) will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid on such Additional Notes, from the
date of issuance of such Additional Notes; provided that if any Note is
surrendered for exchange on or after a record date for an Interest Payment Date
that will occur on or after the date of such exchange, interest on the Note
received in exchange thereof will accrue from the date of such Interest Payment
Date.  The Company will pay interest on overdue principal and, to the extent
lawful, interest on overdue installments of interest and Liquidated Damages, if
any, at a rate of 1% per annum in excess of the interest rate referred to above.

                                       37
<PAGE>

     The principal of, and premium, if any, and interest and Liquidated Damages,
if any, on the Notes shall be payable at the Corporate Trust Office or at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York (each, a "Place of Payment") in the manner
provided in Section 4.01(b); provided, however, that, under the circumstances
set forth in Section 4.01(b), payment of interest and Liquidated Damages on a
Note may be made by wire transfer of immediately available funds to the account
specified by the Holder of a Global Note or by check mailed to the address of
the Person entitled thereto as such address shall appear in the Register.

     Section 3.02.  Denominations.  The Notes shall be issuable only in
registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof.

     Section 3.03. Execution, Authentication and Delivery and Dating. The Notes
shall be executed on behalf of the Company by an Officer of such Company. The
signature of such Officer on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signature of an individual who was at
any time a proper Officer of the Company shall bind the Company, notwithstanding
that such individual has ceased to hold such office prior to the authentication
and delivery of such Notes or did not hold such office at the date of such
Notes.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes for original issue in the aggregate principal amount not to exceed
$500,000,000 and (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Company in the form of an Officer's
Certificate (an "Authentication Order"), and in the case of clause (ii), upon
receipt by the Trustee of an Opinion of Counsel confirming that the Holders of
the Outstanding Notes will be subject to federal income tax in the same amounts,
in the same manner and at the same times as would have been the case if such
Additional Notes were not issued. Such Officer's Certificates shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes, Additional Notes or
Exchange Notes, that the issuance of such Notes (in the case of Additional
Notes) does not contravene any provision of Article 4 of this Indenture, whether
the Notes are to be issued as one or more Global Notes or Physical Notes, the
name or names of the initial Holder or Holders, and such other information as
the Company may include or the Trustee may reasonably request.

     All Notes shall be dated the date of their authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Note a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

                                       38

     Section 3.04.  Temporary Notes.    Until definitive Notes are ready for
delivery, the Company may prepare and upon receipt of an Authentication Order
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company consider appropriate for temporary Notes. If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable
delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the
office or agency of the Company in a Place of Payment, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Company shall execute and upon receipt of an Authentication Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes of the same series and tenor.

     Section 3.05.  Registration, Registration of Transfer and Exchange.  The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Register") in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of Notes and
of transfers of Notes. The Trustee is hereby appointed "Registrar" for the
purpose of registering Notes and transfers of Notes as herein provided.

     Upon surrender for transfer of any Note at the office or agency of the
Company in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes, of any authorized denominations and of a
like aggregate principal amount.

     At the option of the Holder, Notes may be exchanged for other Notes, of any
authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive; provided that no exchange of Initial Notes or
Initial Additional Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the SEC and the
Trustee shall have received an Officer's Certificate confirming that the
Exchange Offer Registration Statement has been declared effective by the SEC and
an exchange offer thereunder has been consummated.  The Initial Notes or
Additional Notes to be exchanged for the Exchange Notes shall be canceled by the
Trustee.

entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes under this
Section 3.05.

     Section 3.06.  Mutilated, Destroyed, Lost and Stolen Notes.  If (a) any
mutilated Note is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b)  there is delivered to the Company and the Trustee such security
or indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Company or the Trustee that such Note has been
acquired by a bona fide purchaser, the Company shall execute and upon receipt of
an Authentication Order the Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
Outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and ratably with
any and all other Notes duly issued hereunder.

     The provisions of this Section 3.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     Section 3.07.  Payment of Interest Rights Preserved.  Interest and
Liquidated Damages on any Note that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest and Liquidated Damages
specified in Section 3.01.

     Any interest and Liquidated Damages on any Note that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the

                                       40
<PAGE>

relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest shall be paid by the Company, as provided in 3.07(a) or
3.07(b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Notes (or their respective Predecessor Notes) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as provided in this Section 3.07(a).  Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest,
the amount thereof and the Special Record Date and payment date therefor to be
mailed, first class postage prepaid, to each Holder at such Holder's address as
it appears in the Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered on such Special Record Date and shall no longer be payable
pursuant to the following 3.07(b).

     (b)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause (b), such payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest (including
any Liquidated Damages) accrued and unpaid, and to accrue, that were carried by
such other Note.

     Section 3.08.  Persons Deemed Owners.   Prior to due presentment of a Note
for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of (and premium, if any, on) and (subject to Section 3.07) interest
and Liquidated Damages, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Company, the
Subsidiary Guarantors, the Trustee or any agent of the Company,  the Subsidiary
Guarantors or the Trustee shall be affected by notice to the contrary.

     Section 3.09. Cancellation. All Notes surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the

                                       41
<PAGE>

Trustee, be delivered to the Trustee and, if not already canceled, shall be
promptly canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder that the
Company may have acquired in any manner whatsoever, and all Notes so delivered
shall be promptly canceled by the Trustee. No Notes shall be authenticated in
lieu of or in exchange for any Notes canceled as provided in this Section 3.09,
except as expressly permitted by this Indenture. All canceled Notes held by the
Trustee shall be disposed of in accordance with the Trustee's customary
procedures.

     Section 3.10.  Computation of Interest.  Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

     Section 3.11.  Payment of Liquidated Damages.  (a)  Under certain
circumstances the Company will be obligated to pay certain Liquidated Damages to
the Holders of certain Initial Notes, as more particularly set forth in such
Initial Notes.

     (b)  Under certain circumstances the Company may be obligated to pay
certain Liquidated Damages to the Holders of certain Initial Additional Notes,
as may be more particularly set forth in such Initial Additional Notes.

     Section 3.12.  CUSIP Numbers.  The Company in issuing the Notes may use
"CUSIP" or "CINS" numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such "CUSIP" or "CINS" numbers in
addition to serial numbers in notices of redemption, repurchase or other notices
to Holders as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such "CUSIP" or "CINS"
numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Notes, and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the "CUSIP" or
"CINS" numbers.

     Section 3.13.  Book-entry Provisions for Global Notes.

     (a)  Each Global Note initially shall (i) be registered in the name of the
Depositary for such Global Notes or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) to the
extent relevant thereto, bear legends as set forth in Section 2.03.  None of the
Company or the Subsidiary Guarantors, nor any of their agents shall have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of beneficial ownership interests of, a Global Note, or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note, and the
Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Subsidiary
Guarantors, the Trustee or any agent of the

                                       42
<PAGE>

Company, the Subsidiary Guarantors or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a beneficial owner
of any Note. The registered Holder of a Global Note may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

     (b)  Interests of beneficial owners in a Global Note may be transferred in
accordance with the applicable rules and procedures of the Depositary and the
provisions of Section 3.14.  Transfers of a Global Note shall be limited to
transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees, except (i) upon request of an Agent
Member (for itself or on behalf of a beneficial holder) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary
procedures of the Depositary and (ii) Physical Notes shall be transferred to
beneficial owners in exchange for their beneficial interests in the Global Notes
in the event that (A) the Depositary (1) notifies the Company that it is
unwilling or unable to continue as Depositary for the applicable Global Note and
a successor depositary is not appointed by the Company within 90 days or (2)
the Depositary ceases to be a "Clearing Agency" registered under the Exchange
Act , (B) the Company, at its option, notifies the Trustee in writing that it
elects to cause the issuance of Physical Notes under this Indenture or (C) there
shall have occurred and be continuing a Default or Event of Default.  In
connection with any transfer or exchange of a portion of the beneficial interest
in any Global Note to beneficial owners for Physical Notes pursuant to paragraph
(b) of this Section 3.13, the Registrar shall record on its books and records
(and make a notation on the Global Note of) the date and a decrease in the
principal amount of such Global Note in an amount equal to the beneficial
interest in the Global Note being transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Notes of
like tenor and principal amount of authorized denominations. In connection with
a transfer of an entire Global Note to beneficial owners pursuant to clause (ii)
of this paragraph (b), the applicable Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
the Trustee shall authenticate and deliver, to each beneficial owner identified
by the Depositary in exchange for its beneficial interest in the applicable
Global Note, an equal aggregate principal amount at maturity of Physical Notes
of authorized denominations.

     (c)  Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

     (d)  The Company, the Subsidiary Guarantors, any other obligor upon the
Notes or the Trustee, in the discretion of any of them, may treat as the Act of
a Holder any instrument or writing of any Person that is identified by the
Depositary as the owner of a beneficial interest in the Global Note, provided
that the fact and date of the execution of such instrument or writing is proved
in accordance with Section 1.08(b).

                                       43

     (e)  Any U.S. Physical Note delivered in exchange for an interest in the
U.S. Global Note pursuant to paragraph (b) of this Section shall, except as
otherwise provided in Section 3.14, bear the Private Placement Legend.

Exchange Note in the Exchange Offer pursuant to an effective Registration

                (i) if such transfer is being made by a proposed transferor who
        has checked the box provided for on the form of such Note stating, or
        has otherwise certified to the Company and the Registrar in writing,
        that the sale has been made in compliance with the provisions of Rule
        144A to a transferee who has signed the certification provided for on
        the form of such Note stating, or has otherwise certified to the Company
        and the Registrar in writing, that it is purchasing such Note for its
        own account or an account with respect to which it exercises sole
        investment discretion and that it and any such account is a QIB within
        the meaning of Rule 144A, and is aware that the sale to it is being made
        in reliance on Rule 144A and acknowledges that it has received such
        information regarding the Company as it has requested pursuant to Rule
        144A or has determined not to request such information and that it is
        aware that the transferor is relying upon its foregoing representations
        in order to claim the exemption from registration provided by Rule 144A;
        and

                (ii) if the proposed transferee is or is acting through an Agent
        Member, and the Note to be transferred consists of (A) a Physical Note
        that after transfer is to be evidenced by an interest in a Global Note
        or (B) a beneficial interest in a Global Note that after the transfer is
        to be evidenced by a Physical Note, upon receipt by the Registrar of
        written instructions given in accordance with the Depositary's and the
        Registrar's procedures,

(I) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and an increase in the
principal amount of the transferee Global Note or (y) deliver Physical Notes, in
each case in an amount equal to the principal amount of the Physical Note or
such beneficial interest in such transferor Global Note to be transferred, and
(II) the Trustee shall (x) cancel the Physical Note so transferred or (y)
reflect on its books and records (and make a notation on the relevant Global
Note of) the date and a decrease in the principal amount of such transferor
Global Note, as the case may be.

Act provided by Rule 144 thereunder or (ii) to the Company, the Register shall
register such transfer if it complies with all other requirements of this
Indenture (including Section 3.05 and Section 3.13) and,

                (A) if such transfer is being made by a proposed transferor who
        has checked the box provided for on the form of such Note stating, or
        has otherwise certified to the Company and the Registrar in writing,
        that the sale has been made in compliance with the provisions of Rule
        144 or that such sale has been made to the Company; and

        relevant Global Note of) the date and an increase in the principal
        amount of the transferee Global Note or (y) deliver Physical Notes, in
        each case in an amount equal to the principal amount of the Physical
        Note or such beneficial interest in such transferor Global Note to be
        transferred, and (II) the Trustee shall (x) cancel the Physical Note so
        transferred or (y) reflect on its books and records (and make a notation
        on the relevant Global Note of) the date and a decrease in the principal
        amount of such transferor Global Note, as the case may be; and

require to confirm that, the proposed transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration

Notes are sold or exchanged pursuant to an effective registration statement
under the Securities Act.

     (h)  General. By its acceptance of any Note bearing the Private Placement
Legend, each Holder of such a Note acknowledges the restrictions on transfer of

communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

     In connection with any transfer of any Note, the Trustee, the Registrar,
the Company and the Subsidiary Guarantors shall be entitled to receive, shall be
under no duty to inquire into, may conclusively presume the correctness of, and
shall be fully protected in relying upon the certificates, opinions and other
information referred to herein (or in the forms provided herein, attached hereto
or to the Notes, or otherwise) received from any Holder and any transferee of
any Note regarding the validity, legality and due authorization of any such
transfer, the eligibility of the transferee to receive such Note and any other

entitled to receive a Physical Note may request that the principal amount
thereof be

                                       46

denominations and the Registrar shall comply with such request if all other
transfer restrictions are satisfied.

                                   COVENANTS

     Section 4.01.  Payment of Principal, Premium and Interest.  (a) The Company
will duly and punctually pay the principal of (and premium, if any) and interest
and Liquidated Damages, if any, on the Notes in accordance with the terms of the
Notes and this Indenture. An installment of principal (and premium, if any) or
interest and Liquidated Damages shall be considered paid on the date it is due
if the Trustee or Paying Agent or Paying Agents hold on that date money
designated for and sufficient to pay the installment.

     (b)  Payments (including principal, premium, if any, interest and
Liquidated Damages, if any) in respect of the Notes represented by the Global
Notes, the Holder of which has given wire transfer instructions on or prior to
the relevant record date, shall be made by wire transfer of immediately
available funds to the accounts specified by the Global Note Holder. With
respect to Physical Notes, the Company will make all payments of principal,
premium, if any, interest and Liquidated Damages, if any, at the office or
agency maintained by the Company in The City of New York referred to in Section
4.02 or, at the option of the Company, by mailing a check to each such Holder's
registered address.

     Section 4.02.  Maintenance of Office or Agency.  The Company will maintain
in the Borough of Manhattan, The City of New York an office or agency where
Notes may be presented or surrendered for payment, where Notes may be
surrendered for transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and of
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain such office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee. The
Company hereby designates the Corporate Trust Office as an initial Place of
Payment and as such office of the Company in the Borough of Manhattan, The City
of New York, and appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands so long as such Corporate Trust
Office remains a Place of Payment.

     Section 4.03. Money for Payments to Be Held in Trust. If the Company shall
at any time act as its own Paying Agent, it will, on or before each due date of
the principal of (and premium, if any) or interest and Liquidated Damages, if
any, on, any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest and Liquidated Damages, if any, so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, it will, prior to
each due date of the principal of (and premium, if any) or interest and
Liquidated Damages, if any,

                                       47

on, any Notes, deposit with a Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest and Liquidated Damages, if any, so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium or interest and Liquidated Damages, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

     If the Company is not acting as its own Paying Agent, the Company will
cause any Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 4.03, that such Paying Agent will:

     (a)  hold all sums held by it for the payment of principal of (and premium,
if any) or interest and Liquidated Damages, if any, on Notes in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

     (b)  give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any such payment of principal (and
premium, if any) or interest and Liquidated Damages, if any;

                                       48
<PAGE>

     (c)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d)  acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture and TIA relating to the duties, rights and
liabilities of such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such

                (i) the Company will not, and will not permit any of its
        Restricted Subsidiaries to, directly or indirectly, create, incur,
        issue, assume, Guarantee or otherwise become directly or indirectly
        liable, contingently or otherwise, with respect to (collectively,
        "incur") any Indebtedness (including Acquired Debt);

                (ii) the Company will not, and will not permit any of its
        Restricted Subsidiaries to, issue any Disqualified Stock (including
        Acquired Disqualified Stock);

                (iii) and the Company will not permit any of its Restricted
        Subsidiaries that are not Subsidiary Guarantors to issue any shares of
        Preferred Stock (including Acquired Preferred Stock);

                                       50
<PAGE>

provided, however, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired
Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
Letters of credit and bankers' acceptances shall be deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

     (b)  The foregoing provisions will not apply to:

                (i) the incurrence by the Company of Indebtedness pursuant to
        the Existing Credit Facility (and by its Subsidiaries of Guarantees
        thereof) in an aggregate principal amount at any time outstanding not to
        exceed an amount equal to $3.87 billion less the aggregate amount of all
        mandatory repayments (other than mandatory prepayments triggered solely
        by the issuance of Indebtedness or Preferred Stock of a Finance
        Subsidiary to refinance the Existing Credit Facility) applied to (x)
        repay loans (other than revolving credit loans) outstanding thereunder
        or (y) permanently reduce the revolving credit commitments thereunder;

                (ii) the incurrence by the Company and the Subsidiary Guarantors
        of Indebtedness represented by the Senior Secured Notes issued on the
        Issue Date, the Original Notes (but not any Additional Notes) and the
        Subsidiary Guarantees thereof;

                (iii) the incurrence by the Company and its Restricted
        Subsidiaries of Existing Indebtedness (other than Indebtedness of the
        type described in clauses (i), (ii) or (v) through (xii) of this

                (iv) the incurrence by the Company or any of its Restricted
        Subsidiaries of any Permitted Refinancing in exchange for, or the net
        proceeds of which are used to extend, refinance, renew, replace, defease
        or refund, Indebtedness that was permitted to be incurred under the
        Fixed Charge Coverage Ratio test set forth above or clauses (ii) or
        (iii) above or (xiii) or (xiv) below or this clause (iv);

                (v) the incurrence by the Company or any of its Restricted
        Subsidiaries of intercompany Indebtedness between or among the Company
        and any of its Restricted Subsidiaries; provided, however, that (i) if
        the Company or any Subsidiary Guarantor is the obligor on such
        Indebtedness, such Indebtedness is expressly subordinated to the prior
        payment in full in cash of all Obligations with respect to the Notes or
        the Subsidiary Guarantee, as the case may be, and (ii)(A) any subsequent
        issuance or transfer of Equity Interests that results in any such
        Indebtedness being held by a Person other than the Company or a
        Restricted Subsidiary and (B) any sale or other transfer of any such
        Indebtedness to a Person

                                       51
<PAGE>

        that is not either the Company or a Restricted Subsidiary shall be
        deemed, in each case, to constitute an incurrence of such Indebtedness
        by the Company or such Restricted Subsidiary, as the case may be;

                (vi) the incurrence by the Company or any Restricted Subsidiary
        of Hedging Obligations that are incurred for the purpose of (A) fixing
        or hedging interest rate or currency risk with respect to any fixed or
        floating rate Indebtedness that is permitted by the Indenture to be
        outstanding or any receivable or liability the payment of which is
        determined by reference to a foreign currency; provided that the
        notional principal amount of any such Hedging Obligation does not exceed
        the principal amount of the Indebtedness to which such Hedging
        Obligation relates or (B) fixing or hedging risk with respect to
        fluctuations in the cost of raw materials; provided that such obligation
        is entered into for valid business purposes other than speculative
        purposes (as determined by the Company's or such Restricted Subsidiary's
        principal financial officer in the exercise of his or her good faith
        business judgment);

                (vii) the issuance by any of the Company's Restricted
        Subsidiaries of shares of Preferred Stock to the Company or a Wholly
        Owned Restricted Subsidiary; provided that (A) any subsequent issuance
        or transfer of Equity Interests that results in such Preferred Stock
        being held by a Person other than the Company or a Wholly Owned
        Restricted Subsidiary or (B) the transfer or other disposition by the
        Company or a Wholly Owned Restricted Subsidiary of any such shares to a
        Person other than the Company or a Wholly Owned Restricted Subsidiary
        shall be deemed, in each case, to constitute an issuance of such
        Preferred Stock by such Subsidiary on such date that is not permitted by
        this clause (vii);

                (viii) the incurrence by the Company or any of its Restricted
        Subsidiaries of Indebtedness represented by tender, bid, performance,
        government contract, surety or appeal bonds, standby letters of credit
        and warranty and contractual service obligations of like nature, trade
        letters of credit or documentary letters of credit, in each case to the
        extent incurred in the ordinary course of business of the Company or
        such Restricted Subsidiary and the incurrence by the Company of
        Indebtedness represented by letters of credit incurred in connection
        with the PBGC Settlement;

                (ix) the incurrence by any Restricted Subsidiary of the Company
        of Indebtedness or the issuance by any Restricted Subsidiary of
        Preferred Stock, the aggregate principal amount or liquidation
        preference of which, together with all other Indebtedness and Preferred
        Stock of the Company's Restricted Subsidiaries at the time outstanding
        and incurred or issued in reliance upon this clause (ix), does not
        exceed $50.0 million;

                (x) the issuance by any Finance Subsidiary of Preferred Stock
        with an aggregate liquidation preference not exceeding the amount of
        Indebtedness of the Company held by such Finance Subsidiary; provided
        that the Fixed Charge Coverage Ratio for the Company's most recently
        ended four full fiscal quarters for which financial statements have been
        filed with the SEC pursuant to the

                                       52
<PAGE>

        covenant described below under Section 4.04 immediately preceding the
        date on which such Preferred Stock is issued would have been at least
        2.0 to 1, determined on a pro forma basis (including a pro forma
        application of the net proceeds therefrom) as if such Preferred Stock
        had been issued at the beginning of such four-quarter period;

                (xi) the incurrence of Indebtedness by Foreign Subsidiaries in
        an aggregate principal amount (or accreted value, as applicable) at any
        time outstanding and incurred in reliance upon this clause (xi) not to

                (xii) the Guarantee by any Restricted Subsidiary of Indebtedness
        of the Company or a Restricted Subsidiary that was permitted to be
        incurred by another provision of this covenant;

                (xiii) Acquired Debt or Acquired Disqualified Stock; provided
        that such Indebtedness or Disqualified Stock was not incurred in
        connection with or in contemplation of such Person becoming a Restricted

        such incurrence, the Fixed Charge Coverage Ratio for the Company's most
        recently ended four full fiscal quarters for which financial statements
        have been filed with the SEC pursuant to Section 4.04 immediately
        preceding the date of such incurrence would have been at least 2.0 to 1,
        determined on a pro forma basis;

                (xiv) Indebtedness or Disqualified Stock of a Specified Joint
        Venture or a Subsidiary thereof existing at the time such Specified
        Joint Venture first becomes a Restricted Subsidiary; provided that such
        Indebtedness or Disqualified Stock was not incurred in connection with
        or in contemplation of such Specified Joint Venture becoming a
        Restricted Subsidiary; and provided further that immediately after
        giving effect to such Specified Joint Venture becoming a Restricted

event that an item of Indebtedness or Preferred Stock meets the criteria of more
than one of the categories of permitted Indebtedness described in clauses (i)
through (xvi) above or is entitled to be incurred pursuant to Section 4.06(a),
the Company shall, in its sole discretion, classify such item of Indebtedness or
Preferred Stock in any matter that complies with this covenant and such
Indebtedness or Preferred Stock will be treated as having been incurred pursuant
to the clauses or Section 4.06(a), as the case may be, designated by the
Company.  The amount of Indebtedness issued at a price which is less than the
principal amount thereof shall be equal to the amount of the liability in
respect thereof determined in accordance with GAAP.

not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly:

                (i) declare or pay any dividend or make any distribution on

        Company);

                (ii) purchase, redeem or otherwise acquire or retire for value

        is subordinated by its terms to the Notes or the Subsidiary Guarantees
        issued under the Indenture (other than Indebtedness owed to the Company
        or any Restricted Subsidiary), except, in each case, payment of interest
        or principal at Stated Maturity; or

                (iv) make any Restricted Investment (all such payments and other
        actions set forth in clauses (i) through (iv) above being collectively
        referred to as "Restricted Payments");

amount of any such Restricted Payment, if other than cash, shall be the fair
market value (as conclusively evidenced by a Board Resolution) of the asset(s)
proposed to be transferred by the Company or such Restricted Subsidiary, as the
case may be, pursuant to such Restricted Payment):

        (A) no Default or Event of Default shall have occurred and be continuing
after giving effect thereto; and

        (B) the Company would, at the time of such Restricted Payment and after
giving pro forma effect thereto as if such Restricted Payment had been made at
the beginning of the most recently ended four full fiscal quarters for which
financial

                                       54

preceding the date of such Restricted Payment, have been permitted to incur at
least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage
Ratio test set forth in Section 4.06(a) and

        (C) such Restricted Payment, together with the aggregate of all other
Restricted Payments made by the Company and its Restricted Subsidiaries after
the Issue Date (excluding Restricted Payments permitted by Section 4.07(b)(ii)
(to the extent paid to the Company or any of its Restricted Subsidiaries or to
the extent such distributions are deducted as a minority interest in calculating
Consolidated Net Income), Section 4.07(b)(iii), Section 4.07(b)(iv), Section
4.07(b)(v), Section 4.07(b)(vii), Section 4.07(b)(x), Section 4.07(b)(xiv) and
Section 4.07(b)(xvi) and 50% of any Restricted Payments permitted by Section
4.07(b)(viii)), is less than the sum, without duplication, of:

                (i) 50% of the Consolidated Net Income of the Company for the
                period (taken as one accounting period) from the beginning of
                the first fiscal quarter commencing on April 1, 1999, to the end
                of the Company's most recently ended fiscal quarter for which
                financial statements have been filed with the SEC pursuant to
                Section 4.04 at the time of such Restricted Payment (or, if such
                Consolidated Net Income for such period is a deficit, less 100%
                of such deficit), plus

                (ii) 100% of the aggregate net cash proceeds received by the
                Company or any of its Restricted Subsidiaries from the issue or
                sale (other than to a Subsidiary or Joint Venture of the
                Company) after the Issue Date of Qualified Equity Interests of
                the Company or of debt securities of the Company or any of its
                Restricted Subsidiaries that have been converted into or
                exchanged for such Qualified Equity Interests of the Company,
                plus

                (iii) to the extent that any Restricted Investment (other than a
                Restricted Investment permitted to be made pursuant to Section
                4.07(b)(vii) or Section 4.07(b)(viii) below) that was made after
                the Issue Date is sold for cash or otherwise liquidated, repaid
                or otherwise reduced, including by way of dividend (to the
                extent not included in calculating Consolidated Net Income), for
                cash, the lesser of (A) the cash return with respect to such
                Restricted Investment (less the cost of disposition, if any) and
                (B) the initial amount of such Restricted Investment plus

                (iv) an amount equal to the sum of (A) the net reduction in
                Investments in Unrestricted Subsidiaries resulting from
                dividends, repayments of loans or other transfers of assets (to
                the extent not included in calculating Consolidated Net Income),
                in each case to the Company or any Restricted Subsidiary from
                Unrestricted Subsidiaries and (B) the portion (proportionate to
                the Company's equity interest in such Subsidiary) of the fair
                market value of the net assets of an Unrestricted Subsidiary at
                the time such Unrestricted Subsidiary is designated a Restricted
                Subsidiary; provided, however, that the foregoing sum shall not
                exceed, in the case of any Unrestricted Subsidiary, the amount
                of Restricted Investments (other

                                       55

                Section 4.07(b)(vii) or Section 4.07(b)(viii) below) previously
                made after the Issue Date by the Company or any Restricted
                Subsidiary in such Unrestricted Subsidiary.

     (b)  If, other than with respect to payments made under 4.07(b)(i) and
4.07(b)(xiv) below, no Default or Event of Default shall have occurred and be
continuing after giving effect to such Restricted Payment, the foregoing
provisions will not prohibit the following Restricted Payments:

                (i) the payment of any dividend within 60 days after the date of
        declaration thereof, if at said date of declaration such payment would
        have complied with the provisions of the Indenture;

                (ii) dividends or distributions by any Restricted Subsidiary of
        the Company payable (x) to all holders of a class of Capital Stock of
        such Restricted Subsidiary on a pro rata basis or on a basis that is
        more favorable to the Company; provided that at least 50% of such class
        of Capital Stock is held by the Company and/or one or more of its
        Restricted Subsidiaries or (y) to all holders of a class of Preferred
        Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor
        issued after the Issue Date in compliance with Section 4.06;

                (iii) the payment of cash dividends on any series of
        Disqualified Stock issued after the Issue Date in an aggregate amount
        not to exceed the cash received by the Company since the Issue Date upon
        issuance of such Disqualified Stock;

                (iv) the redemption, repurchase, retirement or other acquisition
        of any Equity Interests of the Company, any Restricted Subsidiary or any
        Joint Venture (or the acquisition of all the outstanding Equity
        Interests of any Person that conducts no operations and has no assets or
        liabilities other than the ownership of Equity Interests in a Joint
        Venture) in exchange for, or out of the net cash proceeds of the
        substantially concurrent sale (other than to a Subsidiary or Joint
        Venture of the Company) of, Qualified Equity Interests of the Company;
        provided that the amount of any such net cash proceeds that are utilized
        for any such redemption, repurchase, retirement or other acquisition
        shall be excluded from clause (C)(ii) of Section 4.07(a);

        Venture of the Company) of Qualified Equity Interests of the Company;
        provided that the amount of any such net cash proceeds that are utilized
        for any such redemption, repurchase, retirement or other acquisition

        in connection with the establishment of such Joint Venture or Restricted

        (iii) of the first paragraph above, the amount of such reduction not to
        exceed the amount of such Investments previously made pursuant to this
        Section 4.07(b)(xv)); and

                (xvi) dividends or distributions by any Joint Venture (other
        than a Specified Joint Venture) to all holders of a class of Capital
        Stock of such Joint Venture permitted by Section 4.07(b)(ii)(x) above;
        provided that after giving effect to such dividends or distributions and
        any related transactions, the Joint Venture making such dividends or
        distributions to such holders is contractually entitled to receive, and
        receives within 180 days before or after the date of such dividends or
        distributions, directly or indirectly, an equivalent or larger cash
        payment from each such holder (other than from a holder that is the

<PAGE>

        expenditures in any future period or amortization of a prepaid cash
        expense in any future period.

     (c)  The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments Section
4.07(a) (except to the extent such Investments were repaid in cash, and, in the
case of a Joint Venture (and any Subsidiary of a Joint Venture) designated as an
Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company,
except to the extent that (1) such Investments were made after the Issue Date or
(2) in the case of a Specified Joint Venture, such Investments were made prior
to the Issue Date). All such outstanding Investments (except as provided in the
parenthetical included in the preceding sentence) will be deemed to constitute
Investments in an amount equal to the fair market value of such Investments at
the time of such designation (as conclusively determined by the Board of
Directors). Such designation will only be permitted if any such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. In the case of any
designation by the Company of a Person as an Unrestricted Subsidiary on the
first day that such Person is a Subsidiary of the Company in accordance with the
provisions of the Indenture, such designation shall be deemed to have occurred
for all purposes of the Indenture simultaneously with, and automatically upon,
such Person becoming a Subsidiary.

     (d)  Not later than the date of making any Restricted Payment, other than
those permitted by Sections 4.07(b)(ii)(x), 4.07(b)(vi), 4.07(b)(x) and
4.07(b)(xiv) above, and not later than the 120th day after making any Restricted
Payment permitted by Section 4.07(b)(vi) above, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

     Section 4.08.  Limitation on Dividend and other Payment Restrictions
affecting Restricted Subsidiaries and Joint Ventures.  (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
restriction on the ability of any Restricted Subsidiary to:

                (i) (A) pay dividends or make any other distributions to the
        Company or any of its Restricted Subsidiaries (1) on its Capital Stock
        or (2) with respect to any other interest or participation in, or
        measured by, its profits or (B) pay any Indebtedness owed to the Company
        or any of its Restricted Subsidiaries;

                (ii) make loans or advances to the Company or any of its
        Restricted Subsidiaries; or

                (iii) transfer any of its properties or assets to the Company or
        any of its Restricted Subsidiaries;

                                       60
<PAGE>

     except for such restrictions existing under or by reason of:

     (a) existing agreements as in effect on the Issue Date;

     (b) Indebtedness permitted by the Indenture to be incurred containing
restrictions on the ability of Restricted Subsidiaries to consummate
transactions of the types described in clauses (i), (ii) or (iii) above not
materially more restrictive than those contained in the Indenture;

     (c) the Indenture and the Senior Secured Notes Indentures;

     (d) applicable law;

     (e) existing restrictions with respect to a Person acquired by the Company
or any of its Restricted Subsidiaries (except to the extent such restrictions
were put in place in connection with or in contemplation of such acquisition),
which restrictions are not applicable to any Person, or the properties or assets
of any Person, other than the Person, or the property or assets of the Person,
so acquired;

     (f) customary non-assignment provisions in leases and other agreements
entered into in the ordinary course of business;

     (g) construction loans and purchase money obligations (including Capital
Lease Obligations) for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (iii) above on the
property so constructed or acquired;

     (h) in the case of clause (iii) above, restrictions contained in security
agreements or mortgages securing Indebtedness of a Restricted Subsidiary to the
extent such restrictions restrict the transfer of the property subject to such
security agreements or mortgages;

     (i) a Permitted Refinancing, provided that the restrictions contained in
the agreements governing such Permitted Refinancing are not materially more
restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced (as conclusively evidenced by a Board
Resolution);

     (j) customary restrictions on a Finance Subsidiary imposed in such Finance
Subsidiary's organizational documents or by the terms of its Preferred Stock;

     (k) any restriction with respect to shares of Capital Stock of a Restricted
Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of such shares of Capital Stock or any restriction with respect to
the assets of a Restricted Subsidiary imposed pursuant to an agreement entered
into for the sale or disposition of such assets or all or substantially all the
Capital Stock of such Restricted Subsidiary pending the closing of such sale or
disposition;

     (l) in the case of any Restricted Subsidiary that is a Joint Venture,
customary restrictions on such Restricted Subsidiary contained in its joint
venture agreement, which

                                       61
<PAGE>

restrictions are consistent with the past practice of the Company and its
Restricted Subsidiaries (as conclusively evidenced by a Board Resolution);

     (m) existing restrictions with respect to a Specified Joint Venture or the
property or assets thereof or a Subsidiary of a Specified Joint Venture or the
property or assets thereof, in each case, at the time such Specified Joint
Venture first becomes a Restricted Subsidiary (except to the extent such
restrictions were put in place in connection with or in contemplation of such
Specified Joint Venture becoming a Restricted Subsidiary), which restrictions
are not applicable to any Person, or the properties or assets of any Person,
other than such Specified Joint Venture or the property or assets thereof or a
Subsidiary of such Specified Joint Venture or the property or assets thereof;
and

     (n) the Existing Credit Facility and related documentation as the same is
in effect on the Issue Date and as amended, modified, extended, renewed,
refunded, refinanced, restated or replaced from time to time; provided that the
Existing Credit Facility and related documentation as so amended, modified,
extended, reviewed, refunded, refinanced, restated or replaced is not materially
more restrictive, taken as a whole, as to the matters enumerated above than the
Existing Credit Facility and related documentation as in effect on the Issue
Date (as conclusively evidenced by a Board Resolution).

     For purposes of determining compliance with this covenant, in the event
that a restriction meets the criteria of more than one of the categories of
permitted restrictions described in clauses (a) through (n) above, the Company
shall, in its sole discretion, classify such restriction in any matter that
complies with this covenant and such restriction will be treated as existing
pursuant to the clauses designated by the Company.

     (b)  The Company will use best efforts (consistent with its contractual
obligations and fiduciary duties to any Joint Venture, in each case, as in
effect on the Issue Date) not to permit any of its Joint Ventures that are not
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any restriction on the ability of such Joint
Venture to:

                (i) (A) pay dividends or make any other distributions to the
        Company or any of its Restricted Subsidiaries (1) on its Capital Stock
        or (2) with respect to any other interest or participation in, or
        measured by, its profits or (B) pay any Indebtedness owed to the Company
        or any of its Restricted Subsidiaries;

                (ii) make loans or advances to the Company or any of its
        Restricted Subsidiaries; or

                (iii) transfer any of its properties or assets to the Company or
        any of its Restricted Subsidiaries;

     except for such restrictions existing under or by reason of:

     (a) such Joint Venture's joint venture agreement or its credit facility
(provided that in each case such restrictions are consistent with the past
practice of the Company);

                                       62
<PAGE>

     (b) in the case of any Joint Venture existing on the Issue Date, its
existing agreements as in effect on the date of the Indenture and as amended,
modified, extended, restated or replaced from time to time; provided that no
such amendment, modification, extension, restatement or replacement results in
agreements that are materially more restrictive, taken as a whole, as to the
matters enumerated above than the existing agreements as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution);

     (c) in the case of LCR, any instrument governing its Indebtedness; and

     (d) the restrictions described in clauses (d), (e), (f), (g), (h), (j), (k)
and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k) to a
Restricted Subsidiary were references to a Joint Venture).

     Section 4.09.  Limitation on Sales of Assets.   (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, consummate an Asset
Sale unless:

                (i) the Company and/or the Restricted Subsidiary, as the case
        may be, receives consideration at the time of such Asset Sale at least
        equal to the fair market value (as conclusively evidenced by a Board
        Resolution set forth in an Officers' Certificate delivered to the
        Trustees) of the assets or Equity Interests issued or sold or otherwise
        disposed of; and

                (ii) at least 80% of the consideration therefor received by the
        Company and/or such Restricted Subsidiary is in the form of

                        (A) cash or Cash Equivalents or

                        (B) a controlling interest or a joint venture interest
                (to the extent otherwise permitted by the Indenture) in a
                business engaged in a Permitted Business or long-term property
                or assets that are used or useful in a Permitted Business;

     provided that the amount of (x) any liabilities (as shown on the Company's
     or such Restricted Subsidiary's most recent balance sheet) of the Company
     or any Restricted Subsidiary (other than contingent liabilities and
     liabilities that are by their terms subordinated to the Notes or any
     guarantee thereof) that are assumed by the transferee of any such assets
     pursuant to a customary novation agreement that releases the Company or
     such Restricted Subsidiary from further liability and (y) any securities,
     notes or other obligations received by the Company or any such Restricted
     Subsidiary from such transferee that are promptly converted by the Company
     or such Restricted Subsidiary into cash (to the extent of the cash
     received), shall be deemed to be cash for purposes of this provision.

     (b)  Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

                (i) to permanently repay Senior Indebtedness (and to
        correspondingly reduce commitments with respect thereto in the case of
        revolving borrowings) of

                                       63
<PAGE>

        the Company or a Subsidiary Guarantor or Indebtedness (and to
        correspondingly reduce commitments with respect thereto in the case of
        revolving borrowings) of any Restricted Subsidiary that is not a
        Subsidiary Guarantor; or

                (ii) to acquire a controlling interest or a joint venture
        interest (to the extent otherwise permitted by the Indentures) in
        another business or, the making of a capital expenditure or the
        acquisition of other long-term assets, in each case, in a Permitted
        Business (or enter into a binding commitment for any such expenditure or
        acquisition); provided that such binding commitment shall be treated as
        a permitted application of Net Proceeds from the date of such commitment
        until and only until the earlier of (x) the date on which such
        expenditure or acquisition is consummated and (y) the 180th day
        following the expiration of the aforementioned 360 day period. If the
        expenditure or acquisition contemplated by such binding commitment is
        not consummated on or before such 180th day and the Company shall not
        have applied such Net Proceeds pursuant to clause (i) above on or before
        such 180th day, such commitment shall be deemed not to have been a
        permitted application of Net Proceeds at any time.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce the revolving Indebtedness under the Existing Credit Facility
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the first sentence of this Section 4.09(b) will be
deemed to constitute "Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $25 million, the
Company will be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and, if the
Company is required to do so under the terms of any other Indebtedness ranking
pari passu with such Notes, such other Indebtedness, on a pro rata basis with
the Notes, that may be purchased out of the Excess Proceeds, at an offer price
in cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
purchase, in accordance with the procedures set forth herein

     Prior to complying with the provisions of this Section 4.09, the Company
will either repay all outstanding Senior Indebtedness or obtain the requisite
consents, if any, under all agreements governing outstanding Senior
Indebtedness, to the extent necessary, to permit the repurchase of Notes
required by this covenant.

     To the extent that the aggregate amount of Notes (and any other pari passu
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offer is less than the Excess Proceeds, the Company may, subject to the
other terms of the Indenture, use any remaining Excess Proceeds for general
corporate purposes.

     If the aggregate principal amount of Notes surrendered by Holders thereof
in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased on a pro rata basis.

     Upon completion of the offer to purchase made under the Indenture, the
amount of Excess Proceeds shall be reset at zero.

                                       64

        (d) The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with any Asset
Sale Offer.

     Section 4.10.  Limitation on Affiliate Transactions.  (a)  The Company will
not, and will not permit any of its Restricted Subsidiaries to, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on an arms-length basis and (ii) the Company delivers
to the Trustee (a) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $10 million, a Board Resolution set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess
of $25 million, an opinion as to the fairness to the Company or such Restricted
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an investment banking firm of national standing; provided that:

     (i) transactions or payments pursuant to any employment arrangements or
employee, officer or director benefit plans or arrangements entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business;

     (ii) transactions between or among the Company and/or its Restricted
Subsidiaries;

     (iii) any Restricted Payment permitted by Section 4.07 of the type
described in clause (i) or (ii) of the first paragraph thereof;

     (iv) customary loans, advances, fees and compensation paid to, and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any of its Restricted Subsidiaries;

     (v) transactions entered into on an arms-length basis in the ordinary
course of business between the Company or any of its Restricted Subsidiaries and
any Joint Venture;

     (vi) sales (including a sale in exchange for a promissory note of or Equity
Interest in such Accounts Receivable Subsidiary) of accounts receivable and the
provision of billing, collection and other services in connection therewith, in
each case, to an Accounts Receivable Subsidiary in connection with any
Receivables Facility; and

     (vii) transactions pursuant to any contract or agreement in effect on the
date of the Indenture as the same may be amended, modified or replaced from time
to time so long as any such contract or agreement as so amended, modified or
replaced is, taken as a whole, no less favorable to the Company and its
Restricted Subsidiaries than the contract or agreement as in effect on the date
of the Indenture (as conclusively evidenced by a Board

                                       65
<PAGE>

Resolution); in each case, shall not be deemed to be Affiliate Transactions and
therefore not subject to the requirements of clauses (i) and (ii) of the initial
sentence above.

     Section 4.11.  Limitation on Liens.  The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien (except Permitted Liens) to secure
Indebtedness or other obligations that are pari passu with or subordinated by
their terms in right of payment to the Notes or the Subsidiary Guarantees on any
asset now owned or hereafter acquired, or any income or profits therefrom,
unless all payments due under the  Indenture and the  Notes or the Subsidiary
Guarantees are secured on an equal and ratable basis with the obligations so
secured (or, if such obligations are subordinated by their terms to the Notes or
the  Subsidiary Guarantees, prior to the obligations so secured) until such time
as such obligations are no longer so secured.

     Section 4.12.  Limitation on Senior Subordinated Indebtedness.  The Company
and the Subsidiary Guarantors will not incur any Indebtedness that pursuant to
its terms is subordinate or junior in right of payment to any Senior
Indebtedness and senior in any respect in right of payment to the Notes or the
Subsidiary Guarantees; provided that the foregoing limitation shall not apply to
distinctions between categories of Senior Indebtedness of the Company or a
Subsidiary Guarantor that exist by reason of any Liens or Guarantees arising or
created in respect of some but not all such Senior Indebtedness.

     Section 4.13. Repurchase of Notes upon a Change in Control.  (a)   Upon the
occurrence of a Change of Control, each Holder will have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to the offer described below
(the "Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control (the "Change of Control Payment Date"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's
request the Trustee will mail, a notice to each Holder offering to repurchase
the Notes held by such Holder pursuant to the procedures specified in such
notice.

     (b)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
applicable Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered, and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officer's
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company.

                                       66
<PAGE>

     The Paying Agent will promptly mail to each Holder of Notes so tendered the
Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such Note will be in a principal amount
of $1,000 or an integral multiple thereof.

     (d)  Prior to complying with the provisions of this covenant, but in any
event within 90 days following a Change of Control, the Company will either
repay all outstanding Senior Indebtedness or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Indebtedness, to the
extent necessary, to permit the repurchase of Notes required by this Section
4.13.

     (e)  The Company 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 at
the same or a higher purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     Section 4.14.  Limitation on Sale and Leaseback Transactions.  The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any Sale and Leaseback Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Leaseback Transaction if: (a) the Company
or such Restricted Subsidiary, as the case may be, could have (i) incurred
Indebtedness in an amount equal to the Attributable Debt relating to such Sale
and Leaseback Transaction pursuant to the Fixed Charge Coverage Ratio test set
forth in Section 4.06(a) (whether or not such covenant has ceased to be
otherwise in effect pursuant to Section 4.17) and (ii) incurred a Lien to secure
such Indebtedness pursuant to Section 4.11 without securing the Notes; and (b)
the gross cash proceeds of such Sale and Leaseback Transaction are at least
equal to the fair market value (as conclusively determined by the Board of
Directors) of the property that is the subject of such Sale and Leaseback
Transaction.

     Section 4.15.  Limitation on Line of Business.  The Company will not, and
will not permit any of its Restricted Subsidiaries to, engage in any business
other than Permitted Businesses, except to such extent as would not be material
to the Company and its Subsidiaries taken as a whole.

     Section 4.16.  Limitation on Accounts Receivable Facilities.  The Company
may, and any of its Restricted Subsidiaries may, sell (including a sale in
exchange for a promissory note of or Equity Interest in such Accounts Receivable
Subsidiary) at any time and from time to time, accounts receivable to any
Accounts Receivable Subsidiary; provided that the aggregate consideration
received in each such sale is at least equal to the aggregate fair market value
of the receivables sold.

     Section 4.17.  Limited Applicability of Covenants when Notes are rated
Investment-Grade. Notwithstanding the foregoing, the Company's and its
Restricted Subsidiaries' obligations to comply with the provisions of Sections
4.06, 4.07, 4.08, 4.09, 4.10, 4.15, 4.16 and 4.21 will terminate and cease to
have any further effect from and after the first date when the Notes are rated
Investment Grade.

     Section 4.18.  Existence.  Subject to Articles 4 and 5 of this Indenture,
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with the respective organizational
documents of the Company and each such Subsidiary and the rights (whether
pursuant to charter, partnership certificate, agreement, statute or otherwise),
material licenses and franchises of the Company and each such Subsidiary;
provided that the Company shall not be required by this Section 4.18 to preserve
any such right, license or franchise, or the existence of any Restricted
Subsidiary, if the Company shall determine that the maintenance or preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries taken as a whole.

     Section 4.19.  Payment of Taxes and Other Claims.  The Company will pay or
discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (a) all material taxes, assessments and governmental charges levied
or imposed upon (i) the Company or any such Subsidiary, (ii) the income or
profits of any such Subsidiary which is a corporation or (iii) the property of
the Company or any such Subsidiary and (b) all material lawful claims for labor
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established in accordance with GAAP.

     Section 4.20.  Maintenance of Properties and Insurance.  The Company will
cause all material assets necessary in the conduct of its business or the
business of any of its Restricted Subsidiaries, to be maintained and kept in
good condition, repair and working order (ordinary wear and tear excepted) and
will cause to be made all necessary repairs, renewals, and replacements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided that nothing in this Section 4.20 shall prevent the Company or any such
Subsidiary from discontinuing the use, operation or maintenance of any of such
assets or disposing or abandoning of any of them, if such discontinuance,
disposal or abandonment is, in the judgment of the Company, desirable in the
conduct of the business of the Company or such Subsidiary.

     The Company will maintain, and will cause each of its Restricted
Subsidiaries to maintain (either in the Company's name or in such Subsidiary's
own name) insurance on all their respective properties consistent with the
insurance maintained on the Issue Date or otherwise in at least such amounts
(with no materially greater risk retention) and against at least such risks as
are usually maintained, retained or insured against in the same general area by
companies of established repute owning similar properties in such area and
engaged in the same or a similar business, in either case, to the extent
available to the Company and its Restricted Subsidiaries on commercially
reasonable terms.

     Section 4.21.  Limitation on Issuance of Guarantees by Restricted
Subsidiaries. (a) The Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee or secure the
payment of any other

                                       68
<PAGE>

Indebtedness of the Company or any of its Restricted Subsidiaries (except
Indebtedness of such Restricted Subsidiary or a Restricted Subsidiary of such
Restricted Subsidiary) unless (i) such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture in the form of Exhibit B hereto
providing for the Guarantee of the payment of the Notes by such Restricted
Subsidiary and shall deliver an Opinion of Counsel to the Trustee pursuant to
paragraph (c) below; provided that this paragraph shall not be applicable to (x)
any Guarantee of any Restricted Subsidiary that existed at the time such Person
became a Restricted Subsidiary and was not incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary, (y) Guarantees
of Indebtedness of a Restricted Subsidiary that is a Foreign Subsidiary by a
Restricted Subsidiary that is a Foreign Subsidiary or (z) the granting of Liens
by a Joint Venture Subsidiary to secure Indebtedness under the Existing Credit
Facility and the Senior Secured Notes. If the Notes are (A) subordinated by
their terms to the Guaranteed Indebtedness, then the Subsidiary Guarantee shall
be subordinated to the guarantee of such Guaranteed Indebtedness, (B) pari passu
with the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be pari
passu with, or senior to, the guarantee of such Guaranteed Indebtedness or (C)
senior to the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be
senior to the guarantee of such Guaranteed Indebtedness at least to the extent
that the Notes are senior to such Guaranteed Indebtedness.

     (b)  Notwithstanding the foregoing, each Subsidiary Guarantee by a
Restricted Subsidiary shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all the Company's and each Restricted Subsidiary's
Capital Stock in such Restricted Subsidiary (which sale, exchange or transfer is
not prohibited by the Indenture) as provided in Section 5.03(b), (ii) the
release or discharge of the Guarantee which resulted in the creation of such
Subsidiary Guarantee (or, in the case of the Subsidiary Guarantees of Lyondell
Chemical Worldwide, Inc. and Lyondell Chemical Nederland, Ltd. issued on the
Issue Date, the release or discharge of its Guarantee of Indebtedness under the
Existing Credit Facility), except a discharge or release by or as a result of
payment under such Guarantee, and (iii) the designation of such Restricted
Subsidiary as an Unrestricted Subsidiary in accordance with the terms of the
Indenture.

        (c) The Opinion of Counsel described above shall be to the effect that
such supplemental indenture has been duly authorized, executed and delivered by
such Subsidiary and constitutes a valid and binding obligation of such
Subsidiary, enforceable against such Subsidiary in accordance with its terms
(subject to customary exceptions).

     Section 4.22.  Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes that consent, waive or agree to amend such term or provision in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

        applicable four-quarter period, be permitted to incur at least $1.00 of
        additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
        set forth in Section 4.06(a). The foregoing shall not prohibit the
        merger or consolidation of a Wholly Owned Restricted Subsidiary with the
        Company; provided that, in connection with any such merger or

        stockholders of the Company.

        (b)  The Company will not lease all or substantially all its assets to

consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, conveyance or other disposition is made shall succeed to,
and be substituted for (so that from and after the date of such consolidation,
merger, sale, assignment, transfer, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation), and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein, and the predecessor Company shall be
released from all its obligations hereunder and under the Notes.

     (b)  The sale, assignment, transfer, lease, conveyance or other disposition
by the Company of all or substantially all its property or assets taken as a
whole to one or more of the Company's Subsidiaries shall not relieve the Company
from its obligations under the Indenture and the Notes.

     Section 5.03. Consolidation, Merger or Sale of Assets by a Subsidiary
Guarantor.  (a) No Subsidiary Guarantor may consolidate with or merge with or
into (whether or not such Subsidiary Guarantor is the surviving Person), another
corporation, Person or entity whether or not affiliated with such Subsidiary
Guarantor unless:

                (i) subject to the provisions of Section 5.03(b) below, the

        indenture in form and substance reasonably satisfactory to the Trustee,
        under the Notes;

                (ii) immediately after giving effect to such transaction, no
        Default or Event of Default exists; and

                (iii) the Company would, at the time of such transaction and
        after giving pro forma effect thereto as if such transaction had
        occurred at the beginning of the applicable four-quarter period, (A)
        have a Consolidated Net Worth immediately after the transaction equal to
        or greater than the Consolidated Net Worth of the Company immediately
        preceding the transaction and (B) except with respect to a consolidation
        or merger with a Person that has no outstanding Indebtedness, be
        permitted to incur at least $1.00 of additional Indebtedness pursuant to

     All the Subsidiary Guarantees issued pursuant to clause (i) above shall in
all respects have the same legal rank and benefit under this Indenture as the

Subsidiary does not perform its payment obligations under such Guarantee within
any grace period provided for in the documentation governing such Guarantee)
and, whether such Indebtedness or Guarantee exists on the date of the indenture
or is thereafter created, which default (a) constitutes a Payment Default or (b)
results in the acceleration of such Indebtedness prior to its Stated Maturity,
and in each case, the principal amount of any such Indebtedness, together with

Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall deny or disaffirm its obligations under the Subsidiary
Guarantees issued thereunder.

     Section 6.02.  Acceleration.  (a) If an Event of Default (other than an
Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Subsidiary Guarantor) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then Outstanding, by written notice to the Company
(and to the Trustee if such notice is given by the Holders (the "Acceleration
Notice")), may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued but unpaid interest and
Liquidated Damages, if any, on all the Notes to be due and payable.  Upon a
declaration of acceleration, such principal, premium, if any, and accrued
interest and Liquidated Damages, if any, shall be immediately due and payable.
If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs
with respect to the Company or any Subsidiary Guarantor, the principal of,
premium, if any, accrued interest and Liquidated Damages, if any, on the Notes
then Outstanding shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

                                       73
<PAGE>

     (b)  If payment of the Notes is accelerated because of an Event of Default,
the Company or the Trustee shall promptly notify the holders of Designated
Senior Indebtedness or the Representative of such holders of the acceleration.

     Section 6.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest and Liquidated Damages on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  All remedies are cumulative
to the extent permitted by law.

     Section 6.04.  Waiver of Past Defaults.  The Holders of at least a majority
in principal amount of the outstanding Notes, by written notice to the Company
and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences under the Notes, if (i) all
existing Events of Default, other than the nonpayment of the principal of and
premium, if any, and interest and Liquidated Damages, if any, on such Notes that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     Section 6.05.  Control by Majority.  The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from the
Holders.

     Section 6.06. Limitation on Suits.  A Holder may not pursue any remedy with
respect to this Indenture or the Notes unless:

     (a)  the Holder gives the Trustee written notice of a continuing Event of
Default;

     (b)  the Holders of at least 25% in aggregate principal amount of
Outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c)  such Holder or Holders offer the Trustee security or indemnity
satisfactory to it against any loss, liability or expense;

                                       74
<PAGE>

     (d)  the Trustee does not comply with the request within 60 days after
receipt thereof and the offer of security or indemnity; and

     (e)  during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes do not give the Trustee a
direction inconsistent with the request.

     Section 6.07.  Rights of Holders to Receive Payment.  Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, interest and Liquidated Damages, if any, on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

     Section 6.08. Collection Suit by Trustee.  If an Event of Default specified
in Section  6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest and Liquidated Damages, if any,
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and Liquidated Damages, if any, and such further amount
as shall be sufficient to cover amounts due the Trustee under Section  7.08,
including the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     Section 6.09.  Trustee May File Proofs of Claim.  The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section  7.08.  To the
extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section  7.08 out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties which the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

                                       75

     Section 6.10.  Priorities.  If the Trustee collects any money pursuant to
this Article, it shall pay out the money in the following order:

     First:  to the Trustee, its agents and attorneys for amounts due under
Section  7.08, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

     Second:  to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, interest and Liquidated Damages, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Notes for principal, premium, if any, interest and Liquidated Damages,
respectively; and

     Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section  6.10 upon five Business Days prior notice to
the Company.

     Section 6.11.  Undertaking for Costs.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section  6.06, or a suit by
Holders of more than 10% in aggregate principal amount of the then Outstanding
Notes.

     Section 6.12.  Restoration of Rights and Remedies.  If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture or any Note and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case the Company, any other obligor upon the Notes, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

     Section 6.13.  Rights and Remedies Cumulative.  No right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 6.14.  Waiver of Stay, Extension or Usury Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time

                                       76
<PAGE>

hereafter in force, that would prohibit or forgive the Company from paying all
or any portion of the principal of (or premium, if any), interest or Liquidated
Damages, if any, on the Notes contemplated herein or in the Notes or that may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenant that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture. However, in the case of any
such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy
of mathematical calculations or other facts stated therein).

     (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

     (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph does not
limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts; and

omits to take in good faith in accordance with a direction received by it
pursuant to Section 6.06.

     (d)  The Trustee may refuse to perform any duty or exercise any right or
power or expend or risk its own funds or otherwise incur any financial liability
unless it receives indemnity satisfactory to it against any loss, liability or
expense.

                                       77
<PAGE>

     (e)  Whether or not therein expressly so provided, every provision of this

protection to the Trustee shall be subject to the provisions of Sections 7.01
and 7.03.

of any Default, the Trustee shall transmit by mail to all Holders, as their
names and addresses appear in the Register, notice of such Default hereunder

waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium (if any) or interest and Liquidated Damages, if
any, on, any Note, the Trustee may withhold such notice if and so long as the
board of directors, the executive committee or a trust committee of Responsible
Officers of the Trustee determines that the withholding of such notice is not
opposed to the interests of the Holders.

     (b) The Trustee shall not be required to take notice or be deemed to have
notice or knowledge of any event or of any Default (except default in the
payment of monies to the Trustee which are required to be paid to the Trustee on
or before a specified date or within a specified time after receipt by the
Trustee of a notice or a certificate which was in fact received), unless the
Trustee shall receive from the Company or a Holder a notice stating that the
same has occurred and is continuing, and specifying the same, and in the absence
of such notice the Trustee may conclusively assume that the same does not exist,
except as aforesaid.

     Section 7.03.  Certain Rights of Trustees.  Subject to the provisions of
Section 7.01:

     (i)  the Trustee may conclusively rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,

evidence of indebtedness or other paper or document believed by it to be genuine

certificate;

     (iii)  whenever in the administration of this Indenture the Trustee shall

be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon the Officer's Certificates of the Company;

     (iv)  the Trustee may consult with counsel of its selection and the written
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

<PAGE>

     (v)  in case an Event of Default occurs and is continuing, the Trustee
shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Holders pursuant
to this Indenture, unless such Holders shall have offered to the Trustee
security or indemnity satisfactory to it against any loss, liability or expense
which might be incurred by it in compliance with such request or direction;

     (vi)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,

attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

     (viii) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act
hereunder.

     Section 7.04.  Not Responsible for Recitals or Issuance of Notes.  The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder and that the
statements made by it in a Statement of Eligibility and Qualification on Form T-
1 supplied to the Company in connection with the registration of any Notes
issued hereunder will be true and accurate subject to the qualifications set
forth therein. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of the Notes or the
proceeds thereof.

     Section 7.05. Trustee's Disclaimer. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company' use of the proceeds from the Notes, it shall not be
responsible for any statement in the offering memorandum for the Notes or in the
Indenture or the Notes (other than its certificate of authentication), the acts
of a prior Trustee hereunder, or the determination as to which beneficial owners
are entitled to receive any notices hereunder.

     Section 7.06.  May Hold Notes.  The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Notes and, subject to

Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

                                       79

     Section 7.07.  Money Held in Trust.  Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.

     Section 7.08.  Compensation and Reimbursement. The Company agrees:

     (a) to pay to the Trustee from time to time such compensation as the
Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

     (b)  to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses, advances and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad
faith; and

     (c)  to indemnify the Trustee and any predecessor Trustee for, and to hold
it harmless against, any loss, damage, claims, liability or expense (including
taxes, other than taxes based on the income of the Trustee) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this trust, including the reasonable costs and
expenses of defending itself against any claim (whether asserted by the Company,
a Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

     The Company' payment obligations pursuant to this Section 7.08 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(g) or 6.01(h), the
expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the TIA, within 90 days the Trustee
shall either eliminate such conflicting interest, apply to the SEC for
permission to continue as Trustee with such conflicting interest, or resign, to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. To the extent permitted by such Act, the Trustee shall
not be deemed to have a conflicting interest by virtue of being a trustee under
this Indenture with respect to Original Notes and Additional Notes, or a trustee
under any other indenture between the Company and the Trustee.

     Section 7.10. Corporate Trustee Required; Eligibility. (a) There shall at
all times be one (and only one) Trustee hereunder. The Trustee shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $100,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 7.10
and to the extent permitted by the TIA, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee

                                       80
<PAGE>

shall cease to be eligible in accordance with the provisions of this Section
7.10, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

     Section 7.11.  Resignation and Removal; Appointment of Successor.  (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 7.12.

     (b)  The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 7.12 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 7.12 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the Trustee being removed may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If at any time:

     (i)  the Trustee shall fail to comply with Section 7.09 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
for at least six months, or

     (ii)  the Trustee shall cease to be eligible under Section 7.10 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

     (iii)  the Trustee shall become incapable of acting or shall be adjudged
bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B) subject
to Section 6.11, any Holder who has been a bona fide Holder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee or Trustees.

     (d)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor Trustee and shall comply with the applicable
requirements of Section 7.12. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of

                                       81
<PAGE>

such appointment in accordance with the applicable requirements of Section 7.12,
become the successor Trustee and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner required by
Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide
Holder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     (e)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.10. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

     Section 7.12.  Acceptance of Appointment by Successor.  (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

     (b)  Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to above.

     (c)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

     Section 7.13.  Merger, Conversion, Consolidation or Succession to Business.
(a) Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

     Section 7.14.  Preferential Collection of Claims Against the Company.  (a)
If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Notes), the Trustee shall be subject to the provisions of
the TIA regarding the collection of claims against the Company (or any such
other obligor).

                                       82
<PAGE>

     Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Company to authenticate the Notes. Any
such appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer, a copy of which instrument shall be promptly furnished to
the Company. Unless limited by the terms of such appointment, an Authenticating
Agent may authenticate Notes whenever the Trustee may do so. Each reference in
this Indenture to authentication (or execution of a certificate of
authentication) by the Trustee includes authentication (or execution of a
certificate of authentication) by such Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of

     (iv)  to add Subsidiary Guarantees with respect to the Notes, to grant a

     (v)  to add to the covenants of the Company for the benefit of the Holders

<PAGE>

     (vii)  to make any change that does not adversely affect the rights of any
Holder under the Notes or this Indenture, or

     (viii)  to comply with any requirement of the SEC in connection with the
qualification of this Indenture under the TIA or otherwise.

     Section 9.02.  With Consent of Holders.  (a)  Subject to Section 6.07, the
Company, the Trustee and (if applicable) any Subsidiary Guarantor may amend or
supplement this Indenture or the Notes with the written consent of the Holders
of not less than a majority in aggregate principal amount of the Outstanding
Notes, and any past Default or compliance with any provisions may also be waived
with the written consent of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Notes.

     (b)  Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not (with respect to any Notes held by a non-
consenting Holder):

     (i)  change the Stated Maturity of the principal of, or any installment of
interest on, any Note,

     (ii)  reduce the principal amount of or premium, if any, or interest or
Liquidated Damages, if any, on any Note,

     (iii)  reduce any amount payable on redemption of the Notes or upon the
occurrence of an Event of Default or reduce the Change of Control Payment or the

     (vi) reduce the above-stated percentage of outstanding Notes the consent of
whose Holders is necessary to modify or amend the Indenture,

interest or Liquidated Damages, if any, on the Notes (except as set forth in
Section 6.04),

     (viii)  reduce the percentage or aggregate principal amount of outstanding

<PAGE>

     (x)  release any Subsidiary Guarantor from any of its obligations under its
Subsidiary Guarantee or the Indenture other than in accordance with the
provisions of the Indenture, or amend or modify any provision relating to such
release;

provided that no modification or change may be made to any provision of this
Indenture adversely affecting the rights of any holder of Senior Indebtedness
then outstanding unless the holders of such Senior Indebtedness (or their
Representative) consent to such modification or change.

     (c)  It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

     (d)  After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by the
Company and that such amendment, supplement or waiver is a valid and binding
agreement of the Company, enforceable against it in accordance with its terms
(subject to customary conditions).

     Section 9.04.  Revocation and Effect of Consents.  (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of that Note or any
Note that evidences all or any part of the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. Subject to the
following paragraph of this Section 9.04, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note by notice to the Trustee or the
Company received by the Trustee or the Company, as the case may be, before the
date on which the Trustee receives an Officer's Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver as set forth in Section 1.08.

     (b)  After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (i)
through (viii) of

                                       86
<PAGE>

Section 9.02(b). In that case, the amendment, supplement or waiver shall bind
each Holder of a Note who has consented to it and every subsequent Holder of
such Note or any Note that evidences all or any part of the same debt as the
consenting Holder's Note.

     Section 9.05.  Conformity with TIA.  (a) Every amendment or supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the TIA as then in effect.

     Section 9.06.  Notation on or Exchange of Notes.  (a)  If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Company and in accordance with the specific written direction of the
Company) request the Holder to deliver its Note to the Trustee. The Trustee
shall (if required by the Company and in accordance with the specific written
direction of the Company) place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Company or the
Trustee so determines, the Company in exchange for the Note shall issue and the
Trustee shall authenticate a new Note that reflects the changed terms. Failure
to make the appropriate notation or issue a new Note shall not affect the
validity and effect of such amendment, supplement or waiver.

Trustee of such Redemption Date and of the principal amount of Notes to be

the requirements of the principal national securities exchange, if any, on which
the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by

redemption, the portion of the principal amount thereof to be redeemed. On and
after the Redemption Date, interest and Liquidated Damages will cease to accrue
on Notes or portions thereof called for redemption.

     (b)  For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Notes shall relate, in
the case of any Note redeemed or to be redeemed only in part, to the portion of
the principal of such Note that has been or is to be redeemed.

     (iv)  that on the Redemption Date the Redemption Price will become due and
payable upon each such Note to be redeemed, and that, unless the Company default

the date proposed for the mailing of the notice of such redemption to the
Holders.

     (c)  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note.

     Section 10.06. Deposit of Redemption Price. (a) On or prior to 10:00 a.m.,
New York City time on any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying

4.03) an amount of money sufficient to pay the Redemption Price of, and any
accrued and unpaid interest and Liquidated Damages, if any, on, all the Notes or
portions thereof which are to be redeemed on that date.

     Section 10.07. Notes Payable on Redemption Date. (a) Notice of redemption

pursuant to the terms of this Indenture) such Notes shall cease to bear interest
and Liquidated Damages. Upon surrender of such Notes for redemption in
accordance with such notice, such Notes shall be paid by the Company at the
Redemption Price. Installments of interest and Liquidated Damages, if any, whose
Interest Payment Date is on or prior to the Redemption Date shall be payable to
the Holders of such Notes registered as such on the relevant Regular Record
Dates according to their terms and the provisions of Section 3.07.

Section 10.06, the Notes (or the portions thereof) called for redemption will
cease to accrue interest and Liquidated Damages and the only right of the
Holders of such Notes (or portions thereof) will be to receive payment of the
Redemption Price of, and subject to the last sentence of Section 10.07(a), any
accrued and unpaid interest and Liquidated Damages, if any, on such Notes (or
portions thereof) to the Redemption Date. If any Note (or portion thereof)
called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest
and Liquidated Damages from the Redemption Date at the rate borne by the Note
(or portion thereof).

thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Note without service charge, a new Note or Notes, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Note so
surrendered.

of and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture, when

     (i)  either

obligations of the Company to the Trustee under Section 7.08 and, if money shall
have been deposited with the Trustee pursuant to clause (ii) of Section
11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

                       DEFEASANCE AND COVENANT DEFEASANCE

     Section 12.01.  Option of the Company to Effect Defeasance or Covenant
Defeasance.  The Company may at its option by a Board Resolution, at any time,
elect to have either Section 12.02 or Section 12.03 applied to the Outstanding
Notes upon compliance with the conditions set forth below in this Article 12.

     Section 12.02.  Legal Defeasance and Discharge.  Upon the exercise by the
Company under Section 12.01 of the option applicable to this Section 12.02, the
Company shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this
Section 12.02, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages on such Notes when such payments are
due, (ii) the obligations of the Company with respect to such Notes under
Sections 1.06, 2.03, 3.03, 3.04, 3.05, 3.06, 3.13, 3.14, 4.01, 4.02, 4.03 and
12.05 hereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Company in connection therewith
and with this Article 12.  Subject to compliance with this Article 12, the
Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 hereof with respect to the
Notes.

     Section 12.03. Covenant Defeasance. Upon the exercise by the Company under
Section 12.01 of the option applicable to this Section 12.03, the Company shall
be released from its obligations under the covenants contained in Sections 4.06
through Section 4.17, Section 4.21 and clause (iv) of Section 5.01(a) hereof
with respect to the Outstanding Notes and no Default under Section 6.01(e) and
(f) shall thereafter constitute a Default or Event of Default on the date which
is the 123rd day after the deposit referred to in Section 12.04(a); provided
that all of the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not Outstanding for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed Outstanding for all other purposes hereunder. For this
purpose, such Covenant Defeasance means that, with respect to the Outstanding
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by

                                       92
<PAGE>

reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.01(c) or (d), but, except as specified above, the
remainder of this Indenture and such Notes shall be unaffected thereby.

     Section 12.04.  Conditions to Legal or Covenant Defeasance.  The following
shall be the conditions to application of either Section  12.02 or Section
12.03 to the Outstanding Notes:

     (a)  the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay (i) the principal of, premium, if any, and accrued interest and
Liquidated Damages, if any, on the Notes when such payments are due in
accordance with the terms of this Indenture and the Notes or (ii) in the case of
Legal Defeasance, accrued interest and Liquidated Damages, if any, on the Notes
through a scheduled redemption date and the principal of, and premium on the
Notes on such redemption date; provided that, at the time of deposit, the
Company irrevocably authorize the Trustee to issue a timely notice of redemption
and to take such other steps reasonably requested by the Trustee to ensure that
such redemption will be effectuated;

     (b)  in the case of an election under Section 12.02, the Company has
delivered to the Trustee (i) either (x) 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 the exercise by the Company of its option under this Article 12
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of this Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that, as a result of the creation of
the defeasance trust, the Company will not be required to register under the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund will not be subject to the effect of Section 547 of the
United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor
Law or any comparable provision of applicable law;

     (c)  in the case of an election under Section 12.03, the delivery by the
Company to the Trustee of (i) an Opinion of Counsel to the effect that, among
other things, the 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 amount 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 (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, the Company will not be required to
register under the Investment Company Act of 1940 and after the passage of 123
days

                                       93
<PAGE>

following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or any comparable provision of applicable law;

     (d)  immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound;

     (e)  if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to the
effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge;

     (f)  the Company shall have delivered to the Trustee Officer's Certificates
stating that the deposit made by the Company pursuant to its election under
Sections 12.02 or 12.03 was not made by the Company with the intent of
preferring the Holders over the other creditors of the Company with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others; and

     (g)  the Company shall have delivered to the Trustee Officer's Certificates
and an Opinion of Counsel, each stating that all conditions precedent provided
for relating to either the Legal Defeasance under Section 12.02 or the Covenant
Defeasance under Section 12.03 (as the case may be) have been complied with as
contemplated by this Section 12.04.

     Section 12.05.  Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions.  Subject to Section  12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section  12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section  12.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

     Anything in this Article 12 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or U.S. Government Obligations held by it as provided in
Section  12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants

                                       94
<PAGE>

expressed in a written certification thereof delivered to the Trustee (which may
be the opinion delivered under Section 12.04(a) hereof), are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

     Section 12.06.  Repayment to Company.  Any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest and Liquidated Damages on any
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest and Liquidated Damages has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause
to be published once, in The New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 12.07.  Reinstatement.  If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section  12.02
or 12.03, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section  12.02 or 12.03 until such time as the Trustee or Paying Agent is
permitted to apply all such amounts in accordance with Section  12.02 or 12.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest and Liquidated Damages on
any Note following the reinstatement of its Obligations, the Company shall be
subrogated to the rights of the Holder of such Note to receive such payment from
the amounts held by the Trustee or Paying Agent.



                                  ARTICLE 13
                             SUBSIDIARY GUARANTEES

     Section 13.01.  The Guarantees.  (a) Subject to the provisions of this
Article 13, each Subsidiary Guarantor hereby irrevocably and unconditionally
guarantees, jointly and severally, on an unsecured senior subordinated basis,
the full and punctual payment (whether at Stated Maturity, upon acceleration,
optional redemption, upon repurchase following a Change of Control Offer or an
Asset Sale Offer or otherwise) of the principal of and premium, if any, and
interest and Liquidated Damages, if any, on, and all other amounts payable
under, each Note provided for under this Indenture, and the full and punctual
payment of all other amounts payable by the Company under this Indenture.  Upon
failure by the Company to pay punctually any such amount, each Subsidiary

                                       95
<PAGE>

Guarantor shall forthwith on demand pay the amount not so paid at the place and
in the manner specified in this Indenture.

     Section 13.02.  Guarantee Unconditional.  The obligations of the Subsidiary
Guarantors hereunder shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall, to the fullest extent permitted by law,
not be released, discharged or otherwise affected by:

     (a)  any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Company under this Indenture or any Note, by
operation of law or otherwise;

     (b)  any modification or amendment of or supplement to this Indenture or
any Note; provided that any such modification which increases the obligations of
each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary
Guarantor without its consent;

     (c)  any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Company or its assets or any resulting release or
discharge of any obligation of the Company contained in this Indenture or any
Note;

     (d)  the existence of any claim, set-off or other rights which the
Subsidiary Guarantors may have at any time against the Company, the Trustee or
any other Person, whether in connection with this Indenture or any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

     (e)  any invalidity or unenforceability relating to or against the Company
for any reason of this Indenture or any Note, or any provision of applicable law
or regulation purporting to prohibit the payment by the Company of the principal
of or interest and Liquidated Damages on any Note or any other amount payable by
the Company under this Indenture; or

     (f)  any other act or omission to act or delay of any kind by the Company,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Subsidiary Guarantor's obligations hereunder.

     Section 13.03.  Discharge; Reinstatement.  The Subsidiary Guarantors'
obligations hereunder shall remain in full force and effect until the principal
of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
and all other amounts payable by the Company under this Indenture shall have
been paid in full.  If at any time any payment of the principal of, premium, if
any, or interest and Liquidated Damages, if any, on any Note or any other amount
payable by the Company under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, the Subsidiary Guarantors' obligations hereunder with
respect to such payment shall be reinstated as though such payment had been due
but not made at such time.

                                       96
<PAGE>

     Section 13.04.  Waiver by the Subsidiary Guarantors.  The Subsidiary
Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and
any notice not provided for herein, as well as any requirement that at any time
any action be taken by any Person against the Company or any other Person.

     Section 13.05.  Subrogation and Contribution.  Upon making any payment with
respect to any obligation of the Company under this Article 13, the Subsidiary
Guarantor making such payment shall be subrogated to the rights of the payee
against the Company with respect to such obligation; provided that such
Subsidiary Guarantor shall not enforce either (i) any right to receive payment
by way of subrogation against the Company or against any direct or indirect
security for such obligation, or any other right to be reimbursed, indemnified
or exonerated by or for the account of the Company in respect thereof or (ii)
any right to receive payment, in the nature of contribution or for any other
reason, from any other Subsidiary Guarantor with respect to such payment, in
each case so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

     Section 13.06.  Stay of Acceleration.  If acceleration of the time for
payment of any amount payable by the Company under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of this Indenture
shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on
demand by the Trustee or the Holders.

     Section 13.07. Subordination. Each Subsidiary Guarantor's Obligations under
its Subsidiary Guarantee shall be junior and subordinated in right of payment to
any Senior Indebtedness of such Subsidiary Guarantor in the same manner and to
the same extent as the Notes are subordinated to Senior Indebtedness of the
Company pursuant to Article 14.

     Section 13.08.  Limits of Guarantees.  Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law.  To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the maximum
amount that would not render such Subsidiary Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law.

     Section 13.09.  Execution and Delivery of Note Guarantee.  To evidence its
Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
hereby agrees that this Indenture (or a supplemental indenture in the form of
Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by
one of its Officers.

     The signature of an Officer of a Subsidiary Guarantor on the Indenture
shall bind such Subsidiary Guarantor, notwithstanding that such individual has
ceased to hold such

                                       97
<PAGE>

office prior to the authentication and delivery of any Note or did not hold such
office at the date of such Note.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Indenture on behalf of the Subsidiary Guarantors.



                                  ARTICLE 14
                                 SUBORDINATION

     Section 14.01.  Agreement to Subordinate.  The Company and the Subsidiary
Guarantors agree, and each Holder by accepting a Note agrees, any provision of
this Indenture or the Note to the contrary notwithstanding, that all obligations
owed under and in respect of the Notes and the Subsidiary Guarantees are
subordinated in right of payment, to the extent and in the manner provided in
this Article 14, to the prior payment in full of all Senior Indebtedness of the
Company and the Subsidiary Guarantors, and that the subordination of the Notes
and the Subsidiary Guarantees pursuant to this Article 14 is for the benefit of
all holders of all Senior Indebtedness of the Company and Subsidiary Guarantors
whether outstanding on the Issue Date or incurred thereafter.

     Section 14.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution
to creditors of the Company or any Subsidiary Guarantor in a liquidation or
dissolution of the Company or such Subsidiary Guarantor or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or any Subsidiary Gurantor or its property, an assignment for the
benefit of creditors or any marshalling of the Company's or a Subsidiary
Guarantor's assets and liabilities, the holders of Senior Indebtedness will be
entitled to receive payment in full in cash or cash equivalents of all
Obligations due in respect of such Senior Indebtedness (including interest after
the commencement of any such proceeding at the rate specified in the applicable
Senior Indebtedness) before the Holders of the Notes will be entitled to receive
any payment with respect to the Subordinated Note Obligations, and until all
Obligations with respect to Senior Indebtedness are paid in full in cash or cash
equivalents, any distribution to which the Holders of the Notes would be
entitled shall be made to the holders of Senior Indebtedness (except that
Holders of Senior Subordinated Notes may receive and retain Permitted Junior
Securities and payments made from the trust described in Section 12.04(a)).

     Section 14.03.  Default on Designated Senior Indebtedness.  (a) The
Companyand the Subsidiary Guarantors also may not make any payment upon or in
respect of the Subordinated Note Obligations (except in Permitted Junior
Securities or from the trust described in Section 12.04(a)) if (i) a default in
the payment of the principal of, or premium, if any, or interest on, or
commitment fees relating to, Designated Senior Indebtedness occurs and is
continuing beyond any applicable period of grace or (ii) any other default
occurs and is continuing with respect to Designated Senior Indebtedness that
permits holders of the Designated Senior Indebtedness as to which such default
relates to accelerate its maturity and the Trustee receives a notice of such
default (a "Payment Blockage Notice") from the Company or the holders of any

                                       98
<PAGE>

Designated Senior Indebtedness. Payments on the Notes may and shall be resumed
(including the payment of any amounts previously blocked by such Payment
Blockage Notice) (x) in the case of a payment default, upon the date on which
such default is cured or waived and (y) in case of a nonpayment default, the
earlier of the date on which such nonpayment default is cured or waived or 179
days after the date on which the applicable Payment Blockage Notice is received,
unless the maturity of any Designated Senior Indebtedness has been accelerated.
No new period of payment blockage may be commenced unless and until 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been waived or cured for a period of not less than 90 days.

     To the extent any payment of Senior Indebtedness (whether by or on behalf
of the Company or the Subsidiary Guarantors, as proceeds of security or
enforcement of any right of setoff or otherwise) is declared to be fraudulent or
preferential, set aside or required to be paid to any receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then
if such payment is recovered by, or paid over to, such receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person, the Senior
Indebtedness or part thereof originally intended to be satisfied shall be deemed
to be reinstated and outstanding as if such payment had not occurred.  To the
extent the obligation to repay any Senior Indebtedness is declared to be
fraudulent, invalid, or otherwise set aside under any bankruptcy, insolvency,
receivership, fraudulent conveyance or similar law, then the obligation so
declared fraudulent, invalid or otherwise set aside (and all other amounts that
would come due with respect thereto had such obligation not been so affected)
shall be deemed to be reinstated and outstanding as Senior Indebtedness for all
purposes hereof as if such declaration, invalidity or setting aside had not
occurred.

     (b)  Notwithstanding anything to the contrary in Section 14.02 or this
Section 14.03, Holders may continue to receive payments from any trust
established pursuant to Section 12.04 prior to occurrence of an event
prohibiting payment of or on the Notes.

     Section 14.04. When Distributions Must Be Paid Over. If the Company or any
Subsidiary Guarantor shall make any payment to the Trustee on account of the
principal of, or premium, if any, or interest and Liquidated Damages, if any,
on, the Notes, or the Holders shall receive from any source any payment on
account of the principal of, premium, if any, or interest and Liquidated
Damages, if any, on, the Notes or any obligation in respect of the Notes, at a
time when such payment is prohibited by this Article 14, the Trustee or such
Holders shall hold such payment in trust for the benefit of, and shall pay over
and deliver to, the holders of the Senior Indebtedness of the Company or such
Subsidiary Guarantor (pro rata as to each of such holders on the basis of the
respective amounts of such Senior Indebtedness held by them) or their
Representative, as their respective interests may appear, for application to the
payment of all outstanding Senior Indebtedness of such Company or Subsidiary
Guarantor until all such Senior Indebtedness has been paid in full, after giving
effect to all other payments or distributions to, or provisions made for, the
holders of Senior Indebtedness of such Company or Subsidiary Guarantor.

                                       99
<PAGE>

     With respect to the holders of Senior Indebtedness of the Company and
Subsidiary Guarantors, the Trustee undertakes to perform only such obligations
on its part as are specifically set forth in this Article 14, and no implied
covenants or obligations with respect to any holders of the Senior Indebtedness
of the Company and the Subsidiary Guarantors shall be read into this Indenture
against the Trustee.  The Trustee shall not be deemed to owe any fiduciary duty
to the holders of the Senior Indebtedness of the Company and the Subsidiary
Guarantors, and shall not be liable to any holders of such Senior Indebtedness
if the Trustee shall pay over or distribute to, or on behalf of, Holders, the
Company, Subsidiary Guarantors or any other Person, money or assets to which any
holders of such Senior Indebtedness are entitled pursuant to this Article 14,
except if such payment is made at a time when a Responsible Officer has actual
knowledge that the terms of this Article 14 prohibit such payment.

     Section 14.05.  Notice.  Neither the Trustee nor the Paying Agent shall at
any time be charged with the knowledge of the existence of any facts that would
prohibit the making of any payment to or by the Trustee or Paying Agent under
this Article 14 unless and until the Trustee or Paying Agent shall have received
written notice thereof from the Company, a Subsidiary Guarantor or one or more
holders of the Senior Indebtedness of the Company or Subsidiary Guarantor or a
representative of any holders of such Senior Indebtedness; and, prior to the
receipt of any such written notice, the Trustee or Paying Agent shall be
entitled to assume conclusively that no such facts exist; provided that if a
Responsible Officer of the Trustee shall not have received the notice provided
for in this Section 14.05 at least one Business Day prior to the date such
payment is due pursuant to the terms hereof, then, notwithstanding anything
herein to the contrary, the Trustee shall have full power and authority to make
such payment and shall not be affected by any notice to the contrary which may
be received by it within one Business Day prior to such date (it being
understood that nothing contained in this Section 14.05 shall limit the rights
of the holders of the Senior Indebtedness of the Company and the Subsidiary
Guarantors to recover any payment pursuant to Section 14.04). The Trustee shall
be entitled to rely on the delivery to it of written notice by a Person
representing itself to be a holder of the Senior Indebtedness of the Company or
a Subsidiary Guarantor (or a Representative thereof) to establish that such
notice has been given.  In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any person as a
holder of Senior Indebtedness of the Company or any Subsidiary Guarantor to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of such Senior Indebtedness held by such person,
the extent to which such person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such person under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment which it may be required to make for the benefit of such person pursuant
to the terms of this Indenture pending judicial determination as to the rights
of such person to receive such payment.

     The Company and the Subsidiary Guarantors shall promptly notify the Trustee
and the Paying Agent in writing of any facts they know that would cause a
payment of principal of, premium, if any, or interest and Liquidated Damages, if
any, on, the Notes or any other obligation in respect of the Notes to violate
this Article 14, but failure to give such notice shall not affect the
subordination of the Notes to the Senior Indebtedness of

                                      100
<PAGE>

the Company and the Subsidiary Guarantors provided in this Article 14 or the
rights of holders of such Senior Indebtedness under this Article 14.

     Section 14.06.  Subrogation.  After all Senior Indebtedness of the Company
and the Subsidiary Guarantors has been paid in full and until the Notes are paid
in full, Holders shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of such Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness to
the extent that distributions otherwise payable to the Holders have been applied
to the payment of such Senior Indebtedness.  A distribution made under this
Article 14 to holders of the Senior Indebtedness of the Company and the
Subsidiary Guarantors that otherwise would have been made to Holders is not, as
between the Company or the relevant Subsidiary Guarantor and the Holders, a
payment by the Company or such relevant Subsidiary Guarantor on its Senior
Indebtedness.

     Section 14.07. Relative Rights. This Article 14 defines the relative rights
of Holders and holders of the Senior Indebtedness of the Company and the
Subsidiary Guarantors. Nothing in this Indenture shall: (1) impair, as between
the Company and the Subsidiary Guarantors and Holders, the obligations of the
Company and the Subsidiary Guarantors, which are absolute and unconditional, to
pay principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes in accordance with their terms; (2) affect the relative rights of
Holders and the creditors of the relevant Company or Subsidiary Guarantor other
than their rights in relation to holders of the Senior Indebtedness of the
relevant Company or Subsidiary Guarantor; or (3) prevent the Trustee or any
Holder from exercising its available remedies upon a Default or Event of
Default, subject to the rights of holders of the Senior Indebtedness to receive
distributions and payments otherwise payable to Holders.

     The failure to make a payment on account of principal of or interest and
Liquidated Damages, if any, on the Notes by reason of any provision of this
Article 14 shall not be construed as preventing the occurrence of an Event of
Default under Section 6.01.

     Section 14.08. The Company, Subsidiary Guarantors and Holders May Not
Impair Subordination. (a) No right of any holder of the Senior Indebtedness of
the Company or any Subsidiary Guarantor to enforce the subordination as provided
in this Article 14 shall at any time or in any way be prejudiced or impaired by
any act or failure to act by the Company or the relevant Subsidiary Guarantor or
by any noncompliance by the Company or the relevant Subsidiary Guarantor with
the terms, provisions and covenants of this Indenture or the Notes or any other
agreement regardless of any knowledge thereof with which any such holder may
have or be otherwise charged.

     (b)  Without in any way limiting Section 14.08(a), the holders of any
Senior Indebtedness of the Company or a Subsidiary Guarantor may, at any time
and from time to time to the extent not otherwise prohibited by this Indenture,
without the consent of or notice to any Holders, without incurring any
liabilities to any Holder and without impairing or releasing the subordination
and other benefits provided in this Indenture or the Holders' obligations to the
holders of such Senior Indebtedness, even if any Holder's right of reimbursement
or subrogation or other right or remedy is affected, impaired or

                                      101
<PAGE>

extinguished thereby, do any one or more of the following: (i) amend, renew,
exchange, extend, modify, increase or supplement in any manner such Senior
Indebtedness or any instrument evidencing or guaranteeing or securing such

outstanding (including, but not limited to, changing the manner, place or terms
of payment or changing or extending the time of payment of, or renewing,
exchanging, amending, increasing or altering, (A) the terms of such Senior
Indebtedness, (B) any security for, or any Guarantee of, such Senior
Indebtedness, (C) any liability of any obligor on such Senior Indebtedness
(including any guarantor) or any liability incurred in respect of such Senior
Indebtedness); (ii) sell, exchange, release, surrender, realize upon, enforce or
otherwise deal with in any manner and in any order any property pledged,
mortgaged or otherwise securing such Senior Indebtedness or any liability of any
obligor thereon, to such holder, or any liability incurred in respect thereof;
(ii) settle or compromise any such Senior Indebtedness or any other liability of
any obligor of such Senior Indebtedness to such holder or any security therefor
or any liability incurred in respect thereof and apply any sums by whomsoever
paid and however realized to any liability (including, without limitation,
payment of any of the Senior Indebtedness of the Company and Subsidiary
Guarantors) in any manner or order; and (iv) fail to take or to record or
otherwise perfect, for any reason or for no reason, any lien or security
interest securing such Senior Indebtedness by whomsoever granted, exercise or
delay in or refrain from exercising any right or remedy against any obligor or
any guarantor or any other Person, elect any remedy and otherwise deal freely
with any obligor and any security for such Senior Indebtedness or any liability
of any obligor to the holders of such Senior Indebtedness or any liability
incurred in respect of such Senior Indebtedness.

     (c)  Each Holder by accepting a Note agrees not to compromise, release,
forgive or otherwise discharge the obligations with respect to such Holder's
Note unless holders of a majority of the outstanding amount of each class of
Senior Indebtedness of the Company and Subsidiary Guarantors consent to such
compromise, release, forgiveness or discharge.

     Section 14.09.  Distribution or Notice to Representative.  Whenever a
distribution is to be made, or a notice given, to holders of Senior Indebtedness
of the Company or a Subsidiary Guarantor, the distribution may be made and the
notice given to their Representative, if any.  If any payment or distribution of
the assets of the Company or a Subsidiary Guarantor is required to be made to
holders of any of the Senior Indebtedness of the Company or such Subsidiary
Guarantor pursuant to this Article 14, the Trustee and the Holders shall be
entitled to rely upon any order or decree of any court of competent
jurisdiction, or upon any certificate of a representative of such Senior
Indebtedness or a custodian, in ascertaining the holders of such Senior
Indebtedness entitled to participate in any such payment or distribution, the
amount to be paid or distributed to holders of such Senior Indebtedness and all
other facts pertinent to such payment or distribution or to this Article 14.

     Section 14.10.  Rights of Trustee and Paying Agent.  The Trustee or Paying
Agent may continue to make payments on the Notes unless prior to any payment
date it has received written notice of facts that would cause a payment of
principal of, or premium, if any, or interest and Liquidated Damages, if any,
on, the Notes to violate this Article  14.  Only the Company, Subsidiary
Guarantors, a Representative of Senior

                                      102
<PAGE>

Indebtedness of the Company or a Subsidiary Guarantor, or a holder of Senior
Indebtedness of the Company or a Subsidiary Guarantor that has no Representative
may give such notice.

     To the extent permitted by the TIA, the Trustee in its individual or any
other capacity may hold Indebtedness of the Company and Subsidiary Guarantors
(including Senior Indebtedness) with the same rights it would have if it were
not Trustee.  Any agent of the Trustee may do the same with like rights.

     Nothing in this Article 14 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.08.

     Section 14.11.  Authorization to Effect Subordination.  Each Holder by its
acceptance thereof authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination as
provided in this Article 14, and appoints the Trustee as such Holder's attorney-
in-fact for any and all such purposes (including, without limitation, the timely
filing of a claim for the unpaid balance of the Note that such Holder holds in
the form required in any insolvency or liquidation proceeding and causing such
claim to be approved).

     If a proper claim or proof of debt in the form required in such proceeding
is not filed by or on behalf of all Holders prior to 30 days before the
expiration of the time to file such claims or proofs, then the holders or a
Representative of any Senior Indebtedness of the Company or any Subsidiary
Guarantor is hereby authorized, and shall have the right (without any duty), to
file an appropriate claim for and on behalf of the Holders.

     Section 14.12. Payment. A payment on account of or with respect to any Note
shall include, without limitation, principal, premium, interest or Liquidated
Damages with respect to or in connection with any optional redemption or
purchase provisions, any direct or indirect payment payable by reason of any
other Indebtedness or obligation being subordinated to the Notes, and any direct
or indirect payment or recovery on any claim as a Holder relating to or arising
out of this Indenture or any Note, or the issuance of any Note, or the
transactions contemplated by this Indenture or referred to herein.

                             [REVERSE SIDE OF NOTE]

                           LYONDELL CHEMICAL COMPANY

                   10 7/8 Senior Subordinated Note due 2009


     (1)  Principal and Interest; Subordination.  The Company agrees to pay the
principal of this Note on May 1, 2009.

     The Company agrees to pay interest on the principal amount of this Note on
each Interest Payment Date, as set forth below, at the rate of 10 7/8% per
annum.

     Interest will be payable semi-annually (to the Holders of record of the
Notes (or any predecessor Notes) at the close of business on the Regular Record
Date immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing November 1, 1999.

     [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated May 17, 1999, among the Company, the Subsidiary
Guarantors party thereto and the Initial Purchasers named therein (the
"Registration Rights Agreement"). In the event that (i) the Company or the
Subsidiary Guarantors fail to file an Exchange Offer Registration Statement with
the SEC on or prior to the 90th day after the Issue Date, (ii) if the Exchange
Offer Registration Statement is not declared effective by the SEC on or prior to
the 210th day after the Issue Date, (iii) if the Exchange Offer is not
consummated on or before the 30th business day after the Exchange Offer
Registration Statement is declared effective, (iv) the Company and the
Subsidiary Guarantors are obligated to file the Shelf Registration Statement and
fail to file the Shelf Registration Statement with the SEC on or prior to the
30th day after such filing obligation arises, (v) the Company and the Subsidiary
Guarantors are obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 60th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Notes during the periods specified
in the Registration Rights Agreement, for such time of non-effectiveness or non-
usability (each, a "Registration Default"), the Company and the Subsidiary
Guarantors agree to pay to the Holder of this Note, if affected thereby,
liquidated damages ("Liquidated Damages") in an amount equal to $0.05 per week
per $1,000 in principal amount of this Note for each week or portion thereof
that the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Notes with respect to each subsequent 90 day period until
all Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.50 per week per $1,000 in principal amount of Notes. The Company
and the Subsidiary Guarantors shall not be required to pay Liquidated Damages
for more than one


                                      A-4
<PAGE>

Registration Default at any given time. Following the cure of all Registration
Defaults, the accrual of Liquidated Damages will cease.]./2/

     Interest on this Note will accrue from the most recent date to which
interest has been paid [on this Note or the Note surrendered in exchange
herefor]/1/ or, if no interest has been paid, from May 17, 1999; provided that,
if there is no existing default in the payment of interest and if this Note is
authenticated between a Regular Record Date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest and Liquidated Damages, to the
extent lawful, at a rate per annum equal to 1% per annum in excess of the rate
of interest applicable to the Notes.

     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Note is issued
subject to such provisions.  Each Holder of this Note, by accepting the same,
(a) agrees to and shall be bound by such provisions, (b) authorizes and directs
the Trustee on its behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in the Indenture and (c) appoints
the Trustee its attorney-in-fact for such purpose.

     (2)  Method of Payment.  The Company will pay interest (except defaulted
interest) on the principal amount of the Notes on each May 1 and November 1 to
the Persons who are Holders (as reflected in the Register at the close of
business on the April 15 and October 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is canceled on registration of
transfer or registration of exchange after such Regular Record Date; provided
that, with respect to the payment of principal, the Company will make payment to
the Holder that surrenders this Note to any Paying Agent on or after May 1,
2009.

     The Company will pay principal, premium, if any, and interest and
Liquidated Damages, if any, in money of the United States that at the time of
payment is legal tender for payment of public and private debts.  Payments
(including principal, premium, if any, and interest and Liquidated Damages, if
any) in respect of the Notes represented by the Global Notes, the Holders of
which have given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Company will make all payments of principal, premium, if any, and interest
and Liquidated Damages, if any, at the office or agency maintained by the
Company for such purposes in The City of New York or, at the Company's option,
by mailing a check to each such Holder's registered address. If a payment date
is a date other than a Business Day, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

/2/  Include only for Initial Note.

                                      A-5
<PAGE>

     (3)  Paying Agent and Registrar.  Initially, the Trustee will act as Paying
Agent and Registrar.  The Company may change any Paying Agent or Registrar upon
written notice thereto.  The Company, any Subsidiary or any Affiliate of any of
them may act as Paying Agent, Registrar or co-registrar.

     (4)  Indenture; Limitations.  The Company issued the Notes under an
Indenture dated as of May 17, 1999 (the "Indenture"), among the Company, the
Subsidiary Guarantors and The Bank of New York, as trustee (the "Trustee").
Capitalized terms herein are used as defined in the Indenture unless otherwise
indicated.  The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "TIA").  The Notes are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of all such terms.  To the extent
permitted by applicable law, in the event of any inconsistency between the terms
of this Note and the terms of the Indenture, the terms of the Indenture shall
control.

     The Notes are unsecured senior subordinated obligations of the Company. The
Indenture limits the initial aggregate principal amount of the Notes to
$500,000,000 but permits the issuance of Additional Notes in an unlimited amount
subject to compliance with the covenants contained in the Indenture and except
as may be limited by applicable law.

     (5)  Optional Redemption. The Notes may be redeemed at the option of the
Company, in whole or in part, at any time and from time to time, on or after May
1, 2004, at the following Redemption Prices (expressed in percentages of
principal amount on the relevant Redemption Date), plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date, if redeemed
during the 12-month period commencing May 1 of each of the years set forth
below:

 YEAR                         REDEMPTION PRICE

2004.........................     105.438%
2005.........................     103.625%
2006.........................     101.812%
2007 and thereafter..........    100.0000%

  Notwithstanding the foregoing, at any time prior to May 1, 2002, the Company
may redeem up to 35% of the original principal amount of the Notes, with the
proceeds of one or more Public Equity Offerings, at the redemption price
(expressed in percentages of principal amount on the relevant Redemption Date)
of 110.875% plus accrued and unpaid interest and Liquidated Damages, if any, to
the Redemption Date; provided, however, that (i) at least 65% of the aggregate
principal amount of the Notes from time to time originally issued under the
Indenture remains Outstanding and is held, directly or indirectly, by Persons
other than the Company and its Affiliates and (ii) such redemption shall occur
within 90 days of the applicable Public Equity Offering.

                                      A-6
<PAGE>

  If less than all the Notes are to be redeemed at any time, selection of Notes
for redemption will be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a pro rata basis, by lot or by
such method as the Trustee shall deem fair and appropriate; provided that no
Notes of $1,000 or less shall be redeemed in part.

  Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder of Notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed.  A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if any, cease to accrue on Notes or portions of them called
for redemption.

  (6)  Repurchase upon a Change in Control and Sale of Assets.  Upon the
occurrence of (a) a Change in Control, each Holder shall have the right to
require that the Company repurchase such Holder's Notes at a purchase price in
cash equal to 101% of the principal amount thereof on the date of purchase, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase and (b) an Asset Sale, the Company may be obligated to make an offer to
purchase on a pro rata basis from the Holders the Notes with the Excess Proceeds
of such Asset Sales at a purchase price equal to 100% of the principal amount of
such Notes plus accrued interest and Liquidated Damages, if any, to the date of
purchase.

  (7)  Denominations; Transfer; Exchange.  The Notes are in fully registered
form without coupons, in denominations of $1,000 and any integral multiples of
$1,000. A Holder may register the transfer or exchange of Notes in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture.

  (8)  Persons Deemed Owners.  A Holder may be treated as the owner of a Note
for all purposes.

  (9)  Unclaimed Money.  If money for the payment of principal, premium, if any,
or interest and Liquidated Damages, if any, remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the Company at its
written request.  After that, Holders entitled to the money must look to the
Company for payment, unless an abandoned property law designates another Person,
and all liability of the Trustee and such Paying Agent with respect to such
money shall cease.

  (10) Discharge Prior to Redemption or Maturity.  If the Company irrevocably
deposits, or causes to be deposited, with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of and  premium, if
any, and accrued interest and Liquidated Damages on the Notes (a) to redemption
or maturity, the Company will be discharged from the Indenture and the Notes,
except in certain

                                      A-7
<PAGE>

circumstances for certain sections thereof, and (b) to redemption or maturity,
the Company will be discharged from certain covenants set forth in the
Indenture.

  (11) Amendment; Supplement; Waiver.  Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
Outstanding, and any existing Default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding.  Without notice to or the consent of any
Holder, the parties thereto may amend the Indenture or the Notes to the extent
set forth in the Indenture.

  (12) Restrictive Covenants.  The Indenture contains certain covenants,
including, without limitation, covenants with respect to the following matters:
(i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted
Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with
Affiliates; (vi) Liens; (vii) Senior Subordinated Indebtedness; (viii)
repurchase of Notes upon a Change in Control; (ix) Sale and Leaseback
Transactions; (x) Subsidiary Guarantees; and (xi) consolidation, merger and sale
of assets.  Within 120 days after the end of each fiscal year, the Company must
report to the Trustee on compliance with such limitations.

  (13) Successor Persons.  When a successor person or other entity (other than a
Subsidiary of the Company) assumes all the obligations of its predecessor under
the Notes and the Indenture, the predecessor person will be released from those
obligations.

  (14) Remedies for Events of Default.  If an Event of Default (other than an
Event of Default specified in Section 6.01(g) or (h) of the Indenture that
occurs with respect to the Company or a Subsidiary Guarantor) occurs and is
continuing under this Indenture, then in every such case the Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding Notes,
by written notice to the Company (and to the Trustee if such notice is given by
the Holders), may, and the Trustee at the written request of such Holders shall,
declare the principal of, premium, if any, and accrued interest and Liquidated
Damages, if any, on all of the Outstanding Notes to be immediately due and
payable.  Upon a declaration of acceleration, such principal of, premium, if
any, and accrued interest and Liquidated Damages, if any, shall be immediately
due and payable. If an Event of Default specified in  Section 6.01(g) or (h) of
the Indenture occurs with respect to the Company or a Subsidiary Guarantor, the
principal of, premium, if any, and accrued interest and Liquidated Damages, if
any, on the Outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.  The Holders of at least a majority in aggregate principal amount of the
Outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if (1) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes that have become due solely by such declaration of acceleration,
have been cured or waived and (2) the recission would not conflict with any
judgment or decree of a court of competent jurisdiction.

  Holders may not enforce the Indenture, the Notes or the Subsidiary Guarantees
except as provided in the Indenture.  The Trustee may require security or
indemnity

                                      A-8
<PAGE>

satisfactory to it before it enforces the Indenture, the Notes or the Subsidiary
Guarantees. The Holders of at least a majority in aggregate principal amount of
the Notes then Outstanding may direct the Trustee in the exercise of any trust
or power in accordance with the terms of the Indenture.

  (15) Subsidiary Guarantees.  Each Subsidiary Guarantor irrevocably and
unconditionally guarantees jointly and severally, on an unsecured senior
subordinated basis, the full and punctual payment (whether at Stated Maturity,
upon acceleration, optional redemption, upon repurchase following a Change of
Control Offer or an Asset Sale Offer or otherwise) of the principal of, premium,
if any, and interest and Liquidated Damages, if any, on, and all other amounts
payable under, this Note provided for under this Indenture, and the full and
punctual payment of all other amounts payable by the Company under the
Indenture; provided that, notwithstanding anything to the contrary herein, the
aggregate amount of the Obligations guaranteed under the Indenture by any
Subsidiary Guarantor shall be limited in amount to the maximum amount that would
not render such Subsidiary Guarantor's obligations subject to avoidance under
the applicable fraudulent conveyance provisions of the United States Bankruptcy
Code or any comparable provision of any applicable state law.

  Each Subsidiary Guarantor's obligations under its Subsidiary Guarantee shall
be subordinated in right of payment to all Senior Indebtedness of such
Subsidiary Guarantor to the extent and in the manner provided in the Indenture.
Each Holder of this Note, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on its behalf
to take such action as may be necessary or appropriate to effectuate the
subordination as provided in the Indenture and (c) appoints the Trustee its
attorney-in-fact for such purpose.

Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"), relating to the registration under the Act of $900 million
aggregate principal amount of 9 5/8% Senior Secured Notes, Series A, Due 2007,
$1 billion aggregate principal amount of 9 7/8% Senior Secured Notes, Series B,

2007, 9 7/8% Senior Secured Notes, Series B, Due 2007 and 10 7/8% Senior
Subordinated Notes Due 2009 (collectively, the "Outstanding Notes") and the
issuance of the related guarantees of the New Notes by LCW and LCNL (the
"Guarantees"), we are passing upon certain legal matters in connection with the
New Notes and the Guarantees for Lyondell, LCW and LCNL. The New Notes are to be
issued under indentures dated as of May 17, 1999 (the "Indentures") among
Lyondell, the Subsidiary Guarantors party thereto and The Bank of New York, as
trustee. At your request, this opinion is being furnished to you for filing as
Exhibit 5.1 to the Registration Statement.

          In our capacity as counsel to Lyondell, LCW and LCNL in connection
with the matters referred to above, we have examined the Certificate of
Incorporation and Bylaws of Lyondell, LCW and LCNL, each as amended to date, and

Lyondell, LCW and LCNL, including minute books of Lyondell, LCW and LCNL as
furnished to us by Lyondell, LCW and LCNL, certificates of public officials and

opinions, we have relied upon certificates of officers of Lyondell, LCW and LCNL
with respect to the accuracy of the material

factual matters contained in such certificates. We have assumed that all
signatures on documents examined by us are genuine, all documents submitted to
us are authentic and all documents submitted as certified or photostatic copies

     The undersigned hereby acknowledges receipt and review of the prospectus
dated ____________, 1999 (the "Prospectus") of Lyondell Chemical Company (the
"Issuer"), Lyondell Chemical Worldwide, Inc. and Lyondell Chemical Nederland,
Ltd. (each a "Subsidiary Guarantor") and this Letter of Transmittal which
together constitute the Issuer's offer to exchange (the "Exchange Offer")
9 5/8% Senior Secured Notes, Series A, Due 2007 (the "New Notes"), the issuance
of which has been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of issued and outstanding
unregistered 9 5/8% Senior Secured Notes, Series A, Due 2007 (the "Outstanding
Notes"). Capitalized terms used but not defined herein have the respective
meanings given to them in the Prospectus.

     The Issuer reserves the right, at any time or from time to time, to extend
the period of time during which the Exchange Offer for the Outstanding Notes is
open, at its discretion, in which event the term "Expiration Date" shall mean
the latest date to which such Exchange Offer is extended.  The Issuer reserves
the right to extend such period independently of any other Exchange Offer.   The
Issuer shall notify The Bank of New York (the "Exchange Agent") of any extension
by oral or written notice and shall make a public announcement thereof no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date.

     Registered Holders of Exchange Notes on the relevant record date for the
first interest payment date following the consummation of an Exchange Offer will
receive interest accruing from the most recent date to which interest has been
paid on the Outstanding Notes or, if no interest has been paid, from ________,
1999. Outstanding Notes accepted for exchange will cease to accrue interest from
and after the date of consummation of an Exchange Offer. Holders whose
Outstanding Notes are accepted for exchange will not receive any payment in
respect of accrued interest on such Outstanding Notes otherwise payable on any
interest payment date the record date for which occurs on or after consummation
of an Exchange Offer.

     This Letter of Transmittal is to be used by a holder of Outstanding Notes
(i) if certificates of Outstanding Notes are to be forwarded herewith or (ii) if
delivery of Outstanding Notes is to be made by book-entry transfer to the
account maintained by the Exchange Agent at The Depository Trust Company (the
"DTC") pursuant to the procedures set forth in the Prospectus under the caption
"The Exchange Offers--Book-entry Transfer" and an "agent's message" is not
delivered as described in the Prospectus under the caption "The Exchange
Offers--Procedures for Tendering--Tendering Through DTC's Automated Tender Offer
Program." Tenders by book-entry transfer may also be made by delivering an
agent's message in lieu of this Letter of Transmittal. Holders of Outstanding
Notes whose Outstanding Notes are not immediately available, or who are unable
to deliver their Outstanding Notes, this Letter of Transmittal and all other
documents required hereby to the Exchange Agent on or prior to the Expiration
Date for the Exchange Offer, or who are unable to complete the procedure for
book-entry transfer on a timely basis, must tender their Outstanding Notes
according to the guaranteed delivery procedures set forth in the prospectus
under the caption "The Exchange Offers--Guaranteed Delivery Procedures." See
Instruction 2 of this Letter of Transmittal. DELIVERY OF DOCUMENTS TO THE BOOK-
ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     The term "holder" with respect to an Exchange Offer for Outstanding Notes
means any person in whose name such Outstanding Notes are registered on the
books of Lyondell Chemical Company, any person who holds such Outstanding Notes
and has obtained a properly completed bond power from the registered holder or
any participant in the DTC system whose name appears on a security position
listing as the holder of such Outstanding Notes and who desires to deliver the
Outstanding Notes by book-entry transfer at DTC.  The undersigned has completed,
executed and delivered this Letter of Transmittal to indicate the action the
undersigned desires to take with respect to such Exchange Offer.  Holders who
wish to tender their Outstanding Notes must complete this Letter of Transmittal
in its entirety (unless such Outstanding Notes are to be tendered by book-entry
transfer and an agent's message is delivered in lieu hereof).

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

     Subject to the terms and conditions of the applicable Exchange Offer, the
undersigned hereby tenders to the Issuer for exchange the principal amount of
Outstanding Notes indicated above.  Subject to and effective upon the acceptance
for exchange of the principal amount of Outstanding Notes tendered in accordance
with this Letter of Transmittal, the undersigned hereby exchanges, assigns and
transfers to, or upon the order of, the Issuer all right, title and interest in
and to the Outstanding Notes tendered for exchange hereby, including all rights
to accrued and unpaid interest thereon as of the Expiration Date.  The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent the
true and lawful agent and attorney-in-fact for the undersigned (with full
knowledge that said Exchange Agent also acts as the agent for the Issuer in
connection with the Exchange Offer) with respect to the tendered Outstanding
Notes with full power of substitution to (i) deliver such Outstanding Notes, or
transfer ownership of such Outstanding Notes on the account books maintained by
the DTC, to the Issuer and deliver all accompanying evidences of transfer and
authenticity, and (ii) present such Outstanding Notes for transfer on the books
of the Issuer and receive all benefits and otherwise exercise all rights of
beneficial ownership of such Outstanding Notes, all in accordance with the terms
of the Exchange Offer.  The power of attorney granted in this paragraph shall be
deemed to be irrevocable and coupled with an interest.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the
Outstanding Notes tendered hereby and to acquire the New Notes issuable upon the
exchange of such tendered Outstanding Notes, and that the Issuer will acquire
good and unencumbered title thereto, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim, when the same are
accepted for exchange by the Issuer as contemplated herein.

     The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretations set forth in no-action letters issued to third
parties by the staff of the Securities and Exchange Commission (the "SEC"),
including Exxon Capital Holdings Corporation (available April 13, 1988), Morgan
Stanley & Co. Incorporated (available June 5, 1991), Shearman & Sterling
(available July 2, 1993) and similar no-action letters (the "Prior No-Action
Letters"), that the New Notes issued in exchange for Outstanding Notes pursuant
to the Exchange Offer may be offered for resale or resold and otherwise
transferred by holders thereof (other than any such holder that is an
"affiliate" of the Issuer or any Subsidiary Guarantor within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holders' business and that
such holders are not engaging in, do not intend to participate in and have no
arrangement or understanding with any person to participate in a distribution of
such New Notes.  The SEC has not, however, considered an Exchange Offer in the
context of a no-action letter and there can be no assurance that the staff of
the SEC would make a similar determination with respect to an Exchange Offer as
in other circumstances.

     The undersigned hereby further represents to the Issuer that (i) the New
Notes to be received are being acquired in the ordinary course of business of
the person receiving such New Notes, whether or not the undersigned, (ii)
neither the undersigned nor any such other person has an arrangement or
understanding with any person to participate in the distribution of the
Outstanding Notes or the New Notes within the meaning of the Securities Act and
(iii) neither the holder nor any such other person is an "affiliate," as defined
in Rule 405 under the Securities Act, of the Issuer or any Subsidiary Guarantor
or, if it is an affiliate, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.   If the
undersigned is not a broker-dealer, the undersigned represents that it is not
engaged in, and does not intend to participate in, a distribution of New Notes.
If the undersigned is a broker-dealer that will receive New Notes for its own
account in exchange for Outstanding Notes, it represents that the New Notes are
being acquired by it as a result of market-making activities or other trading
activities and it acknowledges that it will deliver a Prospectus in connection
with any resale of such New Notes.  By so acknowledging and by delivering a
Prospectus, however, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     The undersigned acknowledges that if the undersigned is tendering
Outstanding Notes in the Exchange Offer with the intention of participating in
any manner in a distribution of the New Notes (i) the undersigned cannot rely on
the position of the staff of the SEC set forth in the Prior No-Action Letters
and, in the absence of an exemption therefrom, must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
the resale transaction of the New Notes, in which case the registration
statement must contain the selling security holder information required by Item
507 or Item 508, as applicable, of Regulation S-K of the SEC, and (ii)  failure
to comply with such requirements in such instance could result in the
undersigned incurring liability for which the undersigned is not indemnified by
the Issuer.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Issuer to be necessary or
desirable to complete the exchange, assignment and transfer of the Outstanding
Notes tendered hereby, including the transfer of such Outstanding Notes on the
account books maintained by the DTC.

     For purposes of the Exchange Offer, the Issuer shall be deemed to have
accepted for exchange validly tendered Outstanding Notes when, as and if the
Issuer gives oral or written notice thereof to the Exchange Agent.  Any tendered
Outstanding Notes that are not accepted for exchange pursuant to the Exchange
Offer for any reason will be returned, without expense, to the undersigned at
the address shown below or at a different address as may be indicated herein
under "Special Delivery Instructions" as promptly as practicable after the
Expiration Date for such Exchange Offer.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and legal representatives. This tender
may be withdrawn only in accordance with the procedures set forth in the section
of the Prospectus entitled "The Exchange Offers--Withdrawal of Tenders."

     The undersigned acknowledges that the Issuer's acceptance of properly
tendered Outstanding Notes pursuant to the procedures described under the
caption "The Exchange Offers--Procedures for Tendering" in the Prospectus and in
the instructions hereto will constitute a binding agreement between the
undersigned and the Issuer upon the terms and subject to the conditions of the
Exchange Offer.  The undersigned further agrees that acceptance of any tendered
Outstanding Notes by the Issuer and the issuance of New Notes in exchange
therefor shall constitute performance in full by the Issuer of their obligations
under the registration rights agreement and that the Issuer shall have no
further obligations or liabilities thereunder for the registration of the
Outstanding Notes or the New Notes.

     The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offers-- Conditions to the Exchange
Offers."  The undersigned recognizes that as a result of these conditions (which
may be waived, in whole or in part, by the Issuer), the Issuer may not be
required to exchange any of the Outstanding Notes tendered hereby.   In such
event, the Outstanding Notes not exchanged will be returned to the undersigned
at the address shown below the signature of the undersigned.

     Unless otherwise indicated under "Special Issuance Instructions," please
issue the New Notes issued in exchange for the Outstanding Notes accepted for
exchange and return any Outstanding Notes not tendered or not exchanged, in the
name(s) of the undersigned (or, in the case of a book-entry delivery of
Outstanding Notes, please credit the account indicated above maintained at the
DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please mail or deliver the New Notes issued in exchange for the
Outstanding Notes accepted for exchange and any Outstanding Notes not tendered
or not exchanged (and accompanying documents, as appropriate) to the undersigned
at the address shown below the undersigned's signature(s). In the event that
both "Special Issuance Instructions" and "Special Delivery Instructions" are
completed, please issue the New Notes issued in exchange for the Outstanding
Notes accepted for exchange in the name(s) of, and return any Outstanding Notes
not tendered or not exchanged to, the person(s) so indicated. The undersigned
recognizes that the Issuer has no obligation pursuant to the "Special Issuance
Instructions" and "Special Delivery Instructions" to transfer any Outstanding
Notes from the name of the registered holder(s) thereof if the Issuer does not
accept for exchange any of the Outstanding Notes so tendered for exchange.

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL
         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES OR
AGENT'S MESSAGE AND BOOK-ENTRY CONFIRMATIONS.   All physically delivered
Outstanding Notes or any confirmation of a book-entry transfer to the Exchange
Agent's account at the DTC of Outstanding Notes tendered by book-entry transfer
(a "Book-entry Confirmation"), as well as a properly completed and duly executed
copy of this Letter of Transmittal or facsimile hereof (or an agent's message in
lieu hereof), and any other documents required by this Letter of Transmittal
must be received by the Exchange Agent at its address set forth herein on or
prior to 5:00 p.m., New York City time, on the Expiration Date for the Exchange
Offer, or the tendering holder must comply with the guaranteed delivery
procedures set forth below.  Outstanding Notes tendered hereby must be in
denominations of principal amount of $1,000 and any integral multiple thereof.
THE METHOD OF DELIVERY OF THE TENDERED OUTSTANDING NOTES, THIS LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE
EXCHANGE AGENT.  INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE HOLDER
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ENSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE ISSUER.

     All questions as to the validity, form, eligibility (including time of
receipt) or acceptance of tendered Outstanding Notes and withdrawal of tendered
Outstanding Notes will be determined by the Issuer in its sole discretion, which
determination will be final and binding.  The Issuer reserves the absolute right
to reject any and all Outstanding Notes not properly tendered or any Outstanding
Notes the Issuer's acceptance of which would, in the opinion of counsel for the
Issuer, be unlawful.  The Issuer also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Outstanding Notes.  The
Issuer's interpretation of the terms and conditions of an Exchange Offer
(including the instructions in this Letter of Transmittal) shall be final and
binding on all parties.  Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within such time as
the Issuer shall determine.  Neither the Issuer, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Outstanding Notes, nor shall any of
them incur any liability for failure to give such notification.  Tenders of
Outstanding Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.  Any Outstanding Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders of Outstanding Notes, unless otherwise provided
in this Letter of Transmittal, as soon as practicable following the Expiration
Date.  See "The Exchange Offers" section of the Prospectus.

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their
Outstanding Notes and (a) whose Outstanding Notes are not immediately available,
or (b) who cannot deliver their Outstanding Notes, this Letter of Transmittal or
any other documents required hereby to the Exchange Agent prior to the
applicable Expiration Date or (c) who are unable to comply with the applicable
procedures under the DTC's Automated Tender Offer Program on a timely basis,
must tender their Outstanding Notes according to the guaranteed delivery
procedures set forth in the Prospectus.  Pursuant to such procedures: (i) such
tender must be made by or through a financial institution (including most banks,
savings and loan associations and brokerage houses) that is a participant in the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Program or the Stock Exchanges Medallion Program approved by the
Securities Transfer Association Inc. (an "Eligible Institution"); (ii) prior to
the applicable Expiration Date, the Exchange Agent must have received from the
Eligible Institution a properly completed and duly executed Notice of Guaranteed
Delivery (by facsimile transmission, mail or hand delivery) or a properly
transmitted agent's message and Notice of Guaranteed Delivery setting forth the
name and address of the holder of the Outstanding Notes, the registration
number(s) of such Outstanding Notes and the total principal amount of
Outstanding Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five New York Stock Exchange trading days after such
Expiration Date, this Letter of Transmittal (or facsimile hereof or an agent's
message in lieu hereof) together with the Outstanding Notes in proper form for
transfer (or a Book-entry Confirmation) and any other documents required by this
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent; and (iii) this Letter of Transmittal (or a facsimile hereof or
an agent's message in lieu hereof) together with the certificates for all
physically tendered Outstanding Notes in proper form for transfer (or Book-entry
Confirmation, as the case may be) and all other

                                      10
<PAGE>

documents required hereby are received by the Exchange Agent within five New
York Stock Exchange trading days after such Expiration Date.

     Any holder of Outstanding Notes who wishes to tender Outstanding Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery prior to 5:00
p.m., New York City time, on the applicable Expiration Date.  Upon request of
the Exchange Agent, a Notice of Guaranteed Delivery will be sent to holders who
wish to tender their Outstanding Notes according to the guaranteed delivery
procedures set forth above.  See "The Exchange Offers--Guaranteed Delivery
Procedures" section of the prospectus.

     3.   TENDER BY HOLDER.  Only a registered holder of Outstanding Notes may
tender such Outstanding Notes in the Exchange Offer.  Any beneficial holder of
Outstanding Notes who is not the registered holder and who wishes to tender
should arrange with the registered holder to execute and deliver this Letter of
Transmittal on his behalf or must, prior to completing and executing this Letter
of Transmittal and delivering his Outstanding Notes, either make appropriate
arrangements to register ownership of the Outstanding Notes in such holder's
name or obtain a properly completed bond power from the registered holder.

     4.   PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  Tenders of Outstanding Notes will be accepted only in integral
multiples of $1,000.  If less than the entire principal amount of any
Outstanding Notes is tendered, the tendering holder should fill in the principal
amount tendered in the third column of the box entitled "Description of
Outstanding Notes Tendered" above.  The entire principal amount of Outstanding
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.  If the entire principal amount of all Outstanding
Notes is not tendered, then Outstanding Notes for the principal amount of
Outstanding Notes not tendered and New Notes issued in exchange for any
Outstanding Notes accepted will be returned to the holder as promptly as
practicable after the Outstanding Notes are accepted for exchange.

     5.   SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND
ENDORSEMENTS; MEDALLION GUARANTEE OF SIGNATURES.  If this Letter of Transmittal
(or facsimile hereof) is signed by the record holder(s) of the Outstanding Notes
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the Outstanding Notes without alteration, enlargement or
any change whatsoever.  If this Letter of Transmittal (or facsimile hereof) is
signed by a participant in the DTC, the signature must correspond with the name
as it appears on the security position listing as the holder of the Outstanding
Notes.

     If any tendered Outstanding Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered holder(s) of Outstanding Notes listed and tendered hereby and the New
Notes issued in exchange therefor are to be issued (or any untendered principal
amount of Outstanding Notes is to be reissued) to the registered holder(s), then
said holder(s) need not and should not endorse any tendered Outstanding Notes,
nor provide a separate bond power.  In any other case, such holder(s) must
either properly endorse the Outstanding Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal, with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

     If this Letter of Transmittal (or facsimile hereof) or any Outstanding
Notes or bond powers are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and, unless waived by the Issuer, evidence satisfactory to the Issuer
of their authority to act must be submitted with this Letter of Transmittal.

     NO SIGNATURE GUARANTEE IS REQUIRED IF (i) THIS LETTER OF TRANSMITTAL (OR
FACSIMILE HEREOF) IS SIGNED BY THE REGISTERED HOLDER(S) OF THE OUTSTANDING NOTES
TENDERED HEREIN (OR BY A PARTICIPANT IN THE DTC WHOSE NAME APPEARS ON A SECURITY
POSITION LISTING AS THE OWNER OF THE TENDERED OUTSTANDING NOTES) AND THE NEW
NOTES ARE TO BE ISSUED DIRECTLY TO SUCH REGISTERED HOLDER(S) (OR, IF SIGNED BY A
PARTICIPANT IN THE DTC, DEPOSITED TO SUCH PARTICIPANT'S ACCOUNT AT THE DTC) AND
NEITHER THE BOX ENTITLED "SPECIAL DELIVERY INSTRUCTIONS" NOR THE BOX

                                      11
<PAGE>

ENTITLED "SPECIAL REGISTRATION INSTRUCTIONS" HAS BEEN COMPLETED, OR (ii) SUCH
OUTSTANDING NOTES ARE TENDERED FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION. IN
ALL OTHER CASES, ALL SIGNATURES ON THIS LETTER OF TRANSMITTAL (OR FACSIMILE
HEREOF) MUST BE GUARANTEED BY AN ELIGIBLE INSTITUTION.

     6.   SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders should
indicate, in the applicable box or boxes, the name and address to which New
Notes or substitute Outstanding Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal.  In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.  Holders tendering
Outstanding Notes by book-entry transfer may request that Outstanding Notes not
exchanged be credited to such account maintained at the DTC as such noteholder
may designate hereon.  If no such instructions are given, such Outstanding Notes
not exchanged will be returned to the name and address (or account number) of
the person signing this Letter of Transmittal.

     7.   TRANSFER TAXES.  The Issuer will pay all transfer taxes, if any,
applicable to the exchange of Outstanding Notes pursuant to an Exchange Offer.
If, however, New Notes or Outstanding Notes for principal amounts not tendered
or accepted for exchange are to be delivered to, or are to be registered or
issued in the name of, any person other than the registered holder of the
Outstanding Notes tendered hereby, or if tendered Outstanding Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Outstanding Notes pursuant to an Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder.  If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with this Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder and the Exchange Agent will retain possession of an amount
of Exchange Notes with a face amount at least equal to the amount of such
transfer taxes due by such tendering holder pending receipt by the Exchange
Agent of the amount of such taxes.

     8.   TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder of any Outstanding Notes or New Notes must provide the Issuer (as payor)
with its correct taxpayer identification number ("TIN"), which, in the case of a
holder who is an individual is his or her social security number.  If the Issuer
is not provided with the correct TIN, the holder or payee may be subject to a
$50 penalty imposed by Internal Revenue Service and backup withholding of 31% on
interest payments on the New Notes.

     To prevent backup withholding, each tendering holder and each prospective
holder must provide such holder's correct TIN by completing the Substitute Form
W-9 set forth herein, certifying that the TIN provided is correct (or that such
holder is awaiting a TIN), and that (i) the holder has not been notified by the
Internal Revenue Service that such holder is subject to backup withholding as a
result of failure to report all interest or dividends or (ii) the Internal
Revenue Service has notified the holder that such holder is no longer subject to
backup withholding.  If the New Notes will be registered in more than one name
or will not be in the name of the actual owner, consult the instructions on
Internal Revenue Service Form W-9, which may be obtained from the Exchange
Agent, for information on which TIN to report.

     Certain foreign individuals and entities will not be subject to backup
withholding or information reporting if they submit a Form W-8, signed under
penalties of perjury, attesting to their foreign status.  A Form W-8 can be
obtained from the Exchange Agent.

     If such holder does not have a TIN, such holder should consult the
instructions on Form W-9 concerning applying for a TIN, check the box in Part 3
of the Substitute Form W-9, write "applied for" in lieu of its TIN and sign and
date the form and the Certificate of Awaiting Taxpayer Identification Number.
Checking this box, writing "applied for" on the form and signing such
certificate means that such holder has already applied for a TIN or that such
holder intends to apply for one in the near future.  If such holder does not
provide its TIN to the Issuer within 60 days, backup withholding will begin and
continue until such holder furnishes its TIN to the Issuer.

     The Issuer reserves the right in its sole discretion to take whatever steps
are necessary to comply with the Issuer's obligations regarding backup
withholding.

     The undersigned hereby acknowledges receipt and review of the prospectus
dated  _________  , 1999 (the "Prospectus") of Lyondell Chemical Company (the
"Issuer"), Lyondell Chemical Worldwide, Inc. and Lyondell Chemical Nederland,
Ltd. (each a "Subsidiary Guarantor") and this Letter of Transmittal which
together constitute the Issuer's offer to exchange (the "Exchange Offer") 9 7/8%
Senior Secured Notes, Series B, Due 2007 (the "New Notes"), the issuance of
which has been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of issued and outstanding
unregistered 9 7/8% Senior Secured Notes, Series B, Due 2007 (the "Outstanding
Notes"). Capitalized terms used but not defined herein have the respective
meanings given to them in the Prospectus.

     The Issuer reserves the right, at any time or from time to time, to extend
the period of time during which the Exchange Offer for the Outstanding Notes is
open, at its discretion, in which event the term "Expiration Date" shall mean
the latest date to which such Exchange Offer is extended.  The Issuer reserves
the right to extend such period independently of any other Exchange Offer.   The
Issuer shall notify The Bank of New York (the "Exchange Agent") of any extension
by oral or written notice and shall make a public announcement thereof no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date.

     Registered Holders of Exchange Notes on the relevant record date for the
first interest payment date following the consummation of an Exchange Offer will
receive interest accruing from the most recent date to which interest has been
paid on the Outstanding Notes or, if no interest has been paid, from ______,
1999. Outstanding Notes accepted for exchange will cease to accrue interest from
and after the date of consummation of an Exchange Offer. Holders whose
Outstanding Notes are accepted for exchange will not receive any payment in
respect of accrued interest on such Outstanding Notes otherwise payable on any
interest payment date the record date for which occurs on or after consummation
of an Exchange Offer.

     This Letter of Transmittal is to be used by a holder of Outstanding Notes
(i) if certificates of Outstanding Notes are to be forwarded herewith or (ii) if
delivery of Outstanding Notes is to be made by book-entry transfer to the
account maintained by the Exchange Agent at The Depository Trust Company (the
"DTC") pursuant to the procedures set forth in the Prospectus under the caption
"The Exchange Offers--Book-entry Transfer" and an "agent's message" is not
delivered as described in the Prospectus under the caption "The Exchange
Offers--Procedures for Tendering--Tendering Through DTC's Automated Tender Offer
Program." Tenders by book-entry transfer may also be made by delivering an
agent's message in lieu of this Letter of Transmittal. Holders of Outstanding
Notes whose Outstanding Notes are not immediately available, or who are unable
to deliver their Outstanding Notes, this Letter of Transmittal and all other
documents required hereby to the Exchange Agent on or prior to the Expiration
Date for the Exchange Offer, or who are unable to complete the procedure for
book-entry transfer on a timely basis, must tender their Outstanding Notes
according to the guaranteed delivery procedures set forth in the prospectus
under the caption "The Exchange Offers--Guaranteed Delivery Procedures." See
Instruction 2 of this Letter of Transmittal. DELIVERY OF DOCUMENTS TO THE BOOK-
ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     The term "holder" with respect to an Exchange Offer for Outstanding Notes
means any person in whose name such Outstanding Notes are registered on the
books of Lyondell Chemical Company, any person who holds such Outstanding Notes
and has obtained a properly completed bond power from the registered holder or
any participant in the DTC system whose name appears on a security position
listing as the holder of such Outstanding Notes and who desires to deliver the
Outstanding Notes by book-entry transfer at DTC.  The undersigned has completed,
executed and delivered this Letter of Transmittal to indicate the action the
undersigned desires to take with respect to such Exchange Offer.  Holders who
wish to tender their Outstanding Notes must complete this Letter of Transmittal
in its entirety (unless such Outstanding Notes are to be tendered by book-entry
transfer and an agent's message is delivered in lieu hereof).

for exchange of the principal amount of Outstanding Notes tendered in accordance
with this Letter of Transmittal, the undersigned hereby exchanges, assigns and
transfers to, or upon the order of, the Issuer all right, title and interest in
and to the Outstanding Notes tendered for exchange hereby, including all rights
to accrued and unpaid interest thereon as of the Expiration Date.  The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent the
true and lawful agent and attorney-in-fact for the undersigned (with full
knowledge that said Exchange Agent also acts as the agent for the Issuer in
connection with the Exchange Offer) with respect to the tendered Outstanding
Notes with full power of substitution to (i) deliver such Outstanding Notes, or
transfer ownership of such Outstanding Notes on the account books maintained by
the DTC, to the Issuer and deliver all accompanying evidences of transfer and

of the Issuer and receive all benefits and otherwise exercise all rights of
beneficial ownership of such Outstanding Notes, all in accordance with the terms
of the Exchange Offer.  The power of attorney granted in this paragraph shall be
deemed to be irrevocable and coupled with an interest.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the
Outstanding Notes tendered hereby and to acquire the New Notes issuable upon the

good and unencumbered title thereto, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim, when the same are
accepted for exchange by the Issuer as contemplated herein.

     The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretations set forth in no-action letters issued to third
parties by the staff of the Securities and Exchange Commission (the "SEC"),
including Exxon Capital Holdings Corporation (available April 13, 1988), Morgan
Stanley & Co. Incorporated (available June 5, 1991), Shearman & Sterling
(available July 2, 1993) and similar no-action letters (the "Prior No-Action
Letters"), that the New Notes issued in exchange for Outstanding Notes pursuant
to the Exchange Offer may be offered for resale or resold and otherwise
transferred by holders thereof (other than any such holder that is an
"affiliate" of the Issuer or any Subsidiary Guarantor within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holders' business and that
such holders are not engaging in, do not intend to participate in and have no
arrangement or understanding with any person to participate in a distribution of
such New Notes.  The SEC has not, however, considered an Exchange Offer in the
context of a no-action letter and there can be no assurance that the staff of
the SEC would make a similar determination with respect to an Exchange Offer as
in other circumstances.

     The undersigned hereby further represents to the Issuer that (i) the New
Notes to be received are being acquired in the ordinary course of business of
the person receiving such New Notes, whether or not the undersigned, (ii)
neither the undersigned nor any such other person has an arrangement or
understanding with any person to participate in the distribution of the
Outstanding Notes or the New Notes within the meaning of the Securities Act and
(iii) neither the holder nor any such other person is an "affiliate," as defined
in Rule 405 under the Securities Act, of the Issuer or any Subsidiary Guarantor
or, if it is an affiliate, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.   If the
undersigned is not a broker-dealer, the undersigned represents that it is not
engaged in, and does not intend to participate in, a distribution of New Notes.
If the undersigned is a broker-dealer that will receive New Notes for its own
account in exchange for Outstanding Notes, it represents that the New Notes are
being acquired by it as a result of market-making activities or other trading
activities and it acknowledges that it will deliver a Prospectus in connection
with any resale of such New Notes.  By so acknowledging and by delivering a
Prospectus, however, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

                                       5

     The undersigned acknowledges that if the undersigned is tendering
Outstanding Notes in the Exchange Offer with the intention of participating in
any manner in a distribution of the New Notes (i) the undersigned cannot rely on
the position of the staff of the SEC set forth in the Prior No-Action Letters
and, in the absence of an exemption therefrom, must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
the resale transaction of the New Notes, in which case the registration
statement must contain the selling security holder information required by Item
507 or Item 508, as applicable, of Regulation S-K of the SEC, and (ii)  failure
to comply with such requirements in such instance could result in the
undersigned incurring liability for which the undersigned is not indemnified by
the Issuer.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Issuer to be necessary or
desirable to complete the exchange, assignment and transfer of the Outstanding
Notes tendered hereby, including the transfer of such Outstanding Notes on the
account books maintained by the DTC.

     For purposes of the Exchange Offer, the Issuer shall be deemed to have
accepted for exchange validly tendered Outstanding Notes when, as and if the
Issuer gives oral or written notice thereof to the Exchange Agent.  Any tendered
Outstanding Notes that are not accepted for exchange pursuant to the Exchange
Offer for any reason will be returned, without expense, to the undersigned at
the address shown below or at a different address as may be indicated herein
under "Special Delivery Instructions" as promptly as practicable after the
Expiration Date for such Exchange Offer.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and legal representatives. This tender
may be withdrawn only in accordance with the procedures set forth in the section
of the Prospectus entitled "The Exchange Offers--Withdrawal of Tenders."

     The undersigned acknowledges that the Issuer's acceptance of properly
tendered Outstanding Notes pursuant to the procedures described under the
caption "The Exchange Offers--Procedures for Tendering" in the Prospectus and in
the instructions hereto will constitute a binding agreement between the
undersigned and the Issuer upon the terms and subject to the conditions of the
Exchange Offer.  The undersigned further agrees that acceptance of any tendered
Outstanding Notes by the Issuer and the issuance of New Notes in exchange
therefor shall constitute performance in full by the Issuer of their obligations
under the registration rights agreement and that the Issuer shall have no
further obligations or liabilities thereunder for the registration of the
Outstanding Notes or the New Notes.

     The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offers--Conditions to the Exchange
Offers."  The undersigned recognizes that as a result of these conditions (which
may be waived, in whole or in part, by the Issuer), the Issuer may not be
required to exchange any of the Outstanding Notes tendered hereby.   In such
event, the Outstanding Notes not exchanged will be returned to the undersigned
at the address shown below the signature of the undersigned.

          Unless otherwise indicated under "Special Issuance Instructions,"
please issue the New Notes issued in exchange for the Outstanding Notes accepted
for exchange and return any Outstanding Notes not tendered or not exchanged, in
the name(s) of the undersigned (or, in the case of a book-entry delivery of
Outstanding Notes, please credit the account indicated above maintained at the
DTC).  Similarly, unless otherwise indicated under "Special Delivery
Instructions," please mail or deliver the New Notes issued in exchange for the
Outstanding Notes accepted for exchange and any Outstanding Notes not tendered
or not exchanged (and accompanying documents, as appropriate) to the undersigned
at the address shown below the undersigned's signature(s).  In the event that
both "Special Issuance Instructions" and "Special Delivery Instructions" are
completed, please issue the New Notes issued in exchange for the Outstanding
Notes accepted for exchange in the name(s) of, and return any Outstanding Notes
not tendered or not exchanged to, the person(s) so indicated.  The undersigned
recognizes that the Issuer has no obligation pursuant to the "Special Issuance
Instructions" and "Special Delivery Instructions" to transfer any Outstanding
Notes from the name of the registered holder(s) thereof if the Issuer does not
accept for exchange any of the Outstanding Notes so tendered for exchange.

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL
        FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES OR
AGENT'S MESSAGE AND BOOK-ENTRY CONFIRMATIONS.   All physically delivered
Outstanding Notes or any confirmation of a book-entry transfer to the Exchange
Agent's account at the DTC of Outstanding Notes tendered by book-entry transfer
(a "Book-entry Confirmation"), as well as a properly completed and duly executed
copy of this Letter of Transmittal or facsimile hereof (or an agent's message in
lieu hereof), and any other documents required by this Letter of Transmittal
must be received by the Exchange Agent at its address set forth herein on or
prior to 5:00 p.m., New York City time, on the Expiration Date for the Exchange
Offer, or the tendering holder must comply with the guaranteed delivery
procedures set forth below.  Outstanding Notes tendered hereby must be in
denominations of principal amount of $1,000 and any integral multiple thereof.
THE METHOD OF DELIVERY OF THE TENDERED OUTSTANDING NOTES, THIS LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE
EXCHANGE AGENT.  INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE HOLDER
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ENSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE ISSUER.

     All questions as to the validity, form, eligibility (including time of
receipt) or acceptance of tendered Outstanding Notes and withdrawal of tendered
Outstanding Notes will be determined by the Issuer in its sole discretion, which
determination will be final and binding.  The Issuer reserves the absolute right
to reject any and all Outstanding Notes not properly tendered or any Outstanding
Notes the Issuer's acceptance of which would, in the opinion of counsel for the
Issuer, be unlawful.  The Issuer also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Outstanding Notes.  The
Issuer's interpretation of the terms and conditions of an Exchange Offer
(including the instructions in this Letter of Transmittal) shall be final and
binding on all parties.  Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within such time as
the Issuer shall determine.  Neither the Issuer, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Outstanding Notes, nor shall any of
them incur any liability for failure to give such notification.  Tenders of
Outstanding Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.  Any Outstanding Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders of Outstanding Notes, unless otherwise provided
in this Letter of Transmittal, as soon as practicable following the Expiration
Date.  See "The Exchange Offers" section of the Prospectus.

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their
Outstanding Notes and (a) whose Outstanding Notes are not immediately available,
or (b) who cannot deliver their Outstanding Notes, this Letter of Transmittal or
any other documents required hereby to the Exchange Agent prior to the
applicable Expiration Date or (c) who are unable to comply with the applicable
procedures under the DTC's Automated Tender Offer Program on a timely basis,
must tender their Outstanding Notes according to the guaranteed delivery
procedures set forth in the Prospectus.  Pursuant to such procedures: (i) such
tender must be made by or through a financial institution (including most banks,
savings and loan associations and brokerage houses) that is a participant in the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Program or the Stock Exchanges Medallion Program approved by the
Securities Transfer Association Inc. (an "Eligible Institution"); (ii) prior to
the applicable Expiration Date, the Exchange Agent must have received from the
Eligible Institution a properly completed and duly executed Notice of Guaranteed
Delivery (by facsimile transmission, mail or hand delivery) or a properly
transmitted agent's message and Notice of Guaranteed Delivery setting forth the
name and address of the holder of the Outstanding Notes, the registration
number(s) of such Outstanding Notes and the total principal amount of
Outstanding Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five New York Stock Exchange trading days after such
Expiration Date, this Letter of Transmittal (or facsimile hereof or an agent's
message in lieu hereof) together with the Outstanding Notes in proper form for
transfer (or a Book-entry Confirmation) and any other documents required by this
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent; and (iii) this Letter of Transmittal (or a facsimile hereof or
an agent's message in lieu hereof) together with the certificates for all
physically tendered Outstanding Notes in proper form for transfer (or Book-entry
Confirmation, as the case may be) and all other

                                       10
<PAGE>

documents required hereby are received by the Exchange Agent within five New
York Stock Exchange trading days after such Expiration Date.

     Any holder of Outstanding Notes who wishes to tender Outstanding Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery prior to 5:00
p.m., New York City time, on the applicable Expiration Date.  Upon request of
the Exchange Agent, a Notice of Guaranteed Delivery will be sent to holders who
wish to tender their Outstanding Notes according to the guaranteed delivery
procedures set forth above.  See "The Exchange Offers--Guaranteed Delivery
Procedures" section of the prospectus.

     3.   TENDER BY HOLDER.  Only a registered holder of Outstanding Notes may
tender such Outstanding Notes in the Exchange Offer.  Any beneficial holder of
Outstanding Notes who is not the registered holder and who wishes to tender
should arrange with the registered holder to execute and deliver this Letter of
Transmittal on his behalf or must, prior to completing and executing this Letter
of Transmittal and delivering his Outstanding Notes, either make appropriate
arrangements to register ownership of the Outstanding Notes in such holder's
name or obtain a properly completed bond power from the registered holder.

     4.   PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  Tenders of Outstanding Notes will be accepted only in integral
multiples of $1,000.  If less than the entire principal amount of any
Outstanding Notes is tendered, the tendering holder should fill in the principal
amount tendered in the third column of the box entitled "Description of
Outstanding Notes Tendered" above.  The entire principal amount of Outstanding
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.  If the entire principal amount of all Outstanding
Notes is not tendered, then Outstanding Notes for the principal amount of
Outstanding Notes not tendered and New Notes issued in exchange for any
Outstanding Notes accepted will be returned to the holder as promptly as
practicable after the Outstanding Notes are accepted for exchange.

     5.   SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND
ENDORSEMENTS; MEDALLION GUARANTEE OF SIGNATURES.  If this Letter of Transmittal
(or facsimile hereof) is signed by the record holder(s) of the Outstanding Notes
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the Outstanding Notes without alteration, enlargement or
any change whatsoever.  If this Letter of Transmittal (or facsimile hereof) is
signed by a participant in the DTC, the signature must correspond with the name
as it appears on the security position listing as the holder of the Outstanding
Notes.

     If any tendered Outstanding Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered holder(s) of Outstanding Notes listed and tendered hereby and the New
Notes issued in exchange therefor are to be issued (or any untendered principal
amount of Outstanding Notes is to be reissued) to the registered holder(s), then
said holder(s) need not and should not endorse any tendered Outstanding Notes,
nor provide a separate bond power.  In any other case, such holder(s) must
either properly endorse the Outstanding Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal, with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

     If this Letter of Transmittal (or facsimile hereof) or any Outstanding
Notes or bond powers are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and, unless waived by the Issuer, evidence satisfactory to the Issuer
of their authority to act must be submitted with this Letter of Transmittal.

     NO SIGNATURE GUARANTEE IS REQUIRED IF (i) THIS LETTER OF TRANSMITTAL (OR
FACSIMILE HEREOF) IS SIGNED BY THE REGISTERED HOLDER(S) OF THE OUTSTANDING NOTES
TENDERED HEREIN (OR BY A PARTICIPANT IN THE DTC WHOSE NAME APPEARS ON A SECURITY
POSITION LISTING AS THE OWNER OF THE TENDERED OUTSTANDING NOTES) AND THE NEW
NOTES ARE TO BE ISSUED DIRECTLY TO SUCH REGISTERED HOLDER(S) (OR, IF SIGNED BY A
PARTICIPANT IN THE DTC, DEPOSITED TO SUCH PARTICIPANT'S ACCOUNT AT THE DTC) AND
NEITHER THE BOX ENTITLED "SPECIAL DELIVERY INSTRUCTIONS" NOR THE BOX

                                       11
<PAGE>

ENTITLED "SPECIAL REGISTRATION INSTRUCTIONS" HAS BEEN COMPLETED, OR (ii) SUCH
OUTSTANDING NOTES ARE TENDERED FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION. IN
ALL OTHER CASES, ALL SIGNATURES ON THIS LETTER OF TRANSMITTAL (OR FACSIMILE
HEREOF) MUST BE GUARANTEED BY AN ELIGIBLE INSTITUTION.

     6.   SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders should
indicate, in the applicable box or boxes, the name and address to which New
Notes or substitute Outstanding Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal.  In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.  Holders tendering
Outstanding Notes by book-entry transfer may request that Outstanding Notes not
exchanged be credited to such account maintained at the DTC as such noteholder
may designate hereon.  If no such instructions are given, such Outstanding Notes
not exchanged will be returned to the name and address (or account number) of
the person signing this Letter of Transmittal.

     7.   TRANSFER TAXES.  The Issuer will pay all transfer taxes, if any,
applicable to the exchange of Outstanding Notes pursuant to an Exchange Offer.
If, however, New Notes or Outstanding Notes for principal amounts not tendered
or accepted for exchange are to be delivered to, or are to be registered or
issued in the name of, any person other than the registered holder of the
Outstanding Notes tendered hereby, or if tendered Outstanding Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Outstanding Notes pursuant to an Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder.  If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with this Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder and the Exchange Agent will retain possession of an amount
of Exchange Notes with a face amount at least equal to the amount of such
transfer taxes due by such tendering holder pending receipt by the Exchange
Agent of the amount of such taxes.

     8.   TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder of any Outstanding Notes or New Notes must provide the Issuer (as payor)
with its correct taxpayer identification number ("TIN"), which, in the case of a
holder who is an individual is his or her social security number.  If the Issuer
is not provided with the correct TIN, the holder or payee may be subject to a
$50 penalty imposed by Internal Revenue Service and backup withholding of 31% on
interest payments on the New Notes.

     To prevent backup withholding, each tendering holder and each prospective
holder must provide such holder's correct TIN by completing the Substitute Form
W-9 set forth herein, certifying that the TIN provided is correct (or that such
holder is awaiting a TIN), and that (i) the holder has not been notified by the
Internal Revenue Service that such holder is subject to backup withholding as a
result of failure to report all interest or dividends or (ii) the Internal
Revenue Service has notified the holder that such holder is no longer subject to
backup withholding.  If the New Notes will be registered in more than one name
or will not be in the name of the actual owner, consult the instructions on
Internal Revenue Service Form W-9, which may be obtained from the Exchange
Agent, for information on which TIN to report.

     Certain foreign individuals and entities will not be subject to backup
withholding or information reporting if they submit a Form W-8, signed under
penalties of perjury, attesting to their foreign status.  A Form W-8 can be
obtained from the Exchange Agent.

     If such holder does not have a TIN, such holder should consult the
instructions on Form W-9 concerning applying for a TIN, check the box in Part 3
of the Substitute Form W-9, write "applied for" in lieu of its TIN and sign and
date the form and the Certificate of Awaiting Taxpayer Identification Number.
Checking this box, writing "applied for" on the form and signing such
certificate means that such holder has already applied for a TIN or that such
holder intends to apply for one in the near future.  If such holder does not
provide its TIN to the Issuer within 60 days, backup withholding will begin and
continue until such holder furnishes its TIN to the Issuer.

     The Issuer reserves the right in its sole discretion to take whatever steps
are necessary to comply with the Issuer's obligations regarding backup
withholding.

                                       12

     9.   VALIDITY OF TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt), acceptance and withdrawal of tendered
Outstanding Notes will be determined by the Issuer in its sole discretion, which
determination will be final and binding.  The Issuer reserves the absolute right
to reject any and all Outstanding Notes not properly tendered or any Outstanding
Notes the Issuer's acceptance of which might, in the opinion of the Issuer or
its counsel, be unlawful.  The Issuer also reserves the absolute right to waive
any conditions of an Exchange Offer or defects or irregularities of tenders as
to particular Outstanding Notes.  The Issuer's interpretation of the terms and
conditions of an Exchange Offer (including this Letter of Transmittal and the
instructions hereto) shall be final and binding on all parties.  Unless waived,
any defects or irregularities in connection with tenders of Outstanding Notes
must be cured within such time as the Issuer shall determine.  Neither the
Issuer, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Outstanding
Notes nor shall any of them incur any liability for failure to give such
notification.

     10.  WAIVER OF CONDITIONS.  The Issuer reserves the absolute right to
waive, in whole or part, any of the conditions to an Exchange Offer set forth in
the Prospectus.

     11.  NO CONDITIONAL TENDER.  No alternative, conditional, irregular or
contingent tender of Outstanding Notes will be accepted.

     12.  MUTILATED, LOST, STOLEN OR DESTROYED OUTSTANDING NOTES.  Any holder
whose Outstanding Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated above for further
instructions.  This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, stolen or destroyed
Outstanding Notes have been followed.

     13.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
or for additional copies of the Prospectus or this Letter of Transmittal may be
directed to the Exchange Agent at the address or telephone number set forth on
the cover page of this Letter of Transmittal.  Holders may also contact their
broker, dealer, commercial bank, trust company or other nominee for assistance
concerning an Exchange Offer.

     14.  WITHDRAWAL.  Tenders may be withdrawn only pursuant to the limited
withdrawal rights set forth in the Prospectus under the caption "The Exchange

     The undersigned hereby acknowledges receipt and review of the prospectus
dated  _________  , 1999 (the "Prospectus") of Lyondell Chemical Company (the
"Issuer"), Lyondell Chemical Worldwide, Inc. and Lyondell Chemical Nederland,
Ltd. (each a "Subsidiary Guarantor") and this Letter of Transmittal which
together constitute the Issuer's offer to exchange (the "Exchange Offer")
10 7/8% Senior Subordinated Notes Due 2009 (the "New Notes"), the issuance of
which has been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of issued and outstanding
unregistered 10 7/8% Senior Subordinated Notes Due 2009 (the "Outstanding
Notes"). Capitalized terms used but not defined herein have the respective
meanings given to them in the Prospectus.

     The Issuer reserves the right, at any time or from time to time, to extend
the period of time during which the Exchange Offer for the Outstanding Notes is
open, at its discretion, in which event the term "Expiration Date" shall mean
the latest date to which such Exchange Offer is extended.  The Issuer reserves
the right to extend such period independently of any other Exchange Offer.   The
Issuer shall notify The Bank of New York (the "Exchange Agent") of any extension
by oral or written notice and shall make a public announcement thereof no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date.

     Registered Holders of Exchange Notes on the relevant record date for the
first interest payment date following the consummation of an Exchange Offer will
receive interest accruing from the most recent date to which interest has been
paid on the Outstanding Notes or, if no interest has been paid, from ________,
1999. Outstanding Notes accepted for exchange will cease to accrue interest from
and after the date of consummation of an Exchange Offer. Holders whose
Outstanding Notes are accepted for exchange will not receive any payment in
respect of accrued interest on such Outstanding Notes otherwise payable on any
interest payment date the record date for which occurs on or after consummation
of an Exchange Offer.

     This Letter of Transmittal is to be used by a holder of Outstanding Notes
(i) if certificates of Outstanding Notes are to be forwarded herewith or (ii) if
delivery of Outstanding Notes is to be made by book-entry transfer to the
account maintained by the Exchange Agent at The Depository Trust Company (the
"DTC") pursuant to the procedures set forth in the Prospectus under the caption
"The Exchange Offers--Book-entry Transfer" and an "agent's message" is not
delivered as described in the Prospectus under the caption "The Exchange
Offers--Procedures for Tendering--Tendering Through DTC's Automated Tender Offer
Program." Tenders by book-entry transfer may also be made by delivering an
agent's message in lieu of this Letter of Transmittal. Holders of Outstanding
Notes whose Outstanding Notes are not immediately available, or who are unable
to deliver their Outstanding Notes, this Letter of Transmittal and all other
documents required hereby to the Exchange Agent on or prior to the Expiration
Date for the Exchange Offer, or who are unable to complete the procedure for
book-entry transfer on a timely basis, must tender their Outstanding Notes
according to the guaranteed delivery procedures set forth in the prospectus
under the caption "The Exchange Offers--Guaranteed Delivery Procedures." See
Instruction 2 of this Letter of Transmittal. DELIVERY OF DOCUMENTS TO THE BOOK-
ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     The term "holder" with respect to an Exchange Offer for Outstanding Notes
means any person in whose name such Outstanding Notes are registered on the
books of Lyondell Chemical Company, any person who holds such Outstanding Notes
and has obtained a properly completed bond power from the registered holder or
any participant in the DTC system whose name appears on a security position
listing as the holder of such Outstanding Notes and who desires to deliver the
Outstanding Notes by book-entry transfer at DTC.  The undersigned has completed,
executed and delivered this Letter of Transmittal to indicate the action the
undersigned desires to take with respect to such Exchange Offer.  Holders who
wish to tender their Outstanding Notes must complete this Letter of Transmittal
in its entirety (unless such Outstanding Notes are to be tendered by book-entry
transfer and an agent's message is delivered in lieu hereof).

     PLEASE READ THE ENTIRE LETTER OF TRANSMITTAL AND THE PROSPECTUS CAREFULLY
BEFORE CHECKING ANY BOX BELOW. THE INSTRUCTIONS INCLUDED WITH THIS LETTER OF
TRANSMITTAL MUST BE FOLLOWED.  QUESTIONS AND REQUESTS FOR ASSISTANCE OR FOR

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

     Subject to the terms and conditions of the applicable Exchange Offer, the
undersigned hereby tenders to the Issuer for exchange the principal amount of
Outstanding Notes indicated above.  Subject to and effective upon the acceptance
for exchange of the principal amount of Outstanding Notes tendered in accordance
with this Letter of Transmittal, the undersigned hereby exchanges, assigns and
transfers to, or upon the order of, the Issuer all right, title and interest in
and to the Outstanding Notes tendered for exchange hereby, including all rights
to accrued and unpaid interest thereon as of the Expiration Date.  The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent the
true and lawful agent and attorney-in-fact for the undersigned (with full
knowledge that said Exchange Agent also acts as the agent for the Issuer in
connection with the Exchange Offer) with respect to the tendered Outstanding
Notes with full power of substitution to (i) deliver such Outstanding Notes, or
transfer ownership of such Outstanding Notes on the account books maintained by
the DTC, to the Issuer and deliver all accompanying evidences of transfer and
authenticity, and (ii) present such Outstanding Notes for transfer on the books
of the Issuer and receive all benefits and otherwise exercise all rights of
beneficial ownership of such Outstanding Notes, all in accordance with the terms
of the Exchange Offer.  The power of attorney granted in this paragraph shall be
deemed to be irrevocable and coupled with an interest.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the
Outstanding Notes tendered hereby and to acquire the New Notes issuable upon the
exchange of such tendered Outstanding Notes, and that the Issuer will acquire
good and unencumbered title thereto, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim, when the same are
accepted for exchange by the Issuer as contemplated herein.

     The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretations set forth in no-action letters issued to third
parties by the staff of the Securities and Exchange Commission (the "SEC"),
including Exxon Capital Holdings Corporation (available April 13, 1988), Morgan
Stanley & Co. Incorporated (available June 5, 1991), Shearman & Sterling
(available July 2, 1993) and similar no-action letters (the "Prior No-Action
Letters"), that the New Notes issued in exchange for Outstanding Notes pursuant
to the Exchange Offer may be offered for resale or resold and otherwise
transferred by holders thereof (other than any such holder that is an
"affiliate" of the Issuer or any Subsidiary Guarantor within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holders' business and that
such holders are not engaging in, do not intend to participate in and have no
arrangement or understanding with any person to participate in a distribution of
such New Notes.  The SEC has not, however, considered an Exchange Offer in the
context of a no-action letter and there can be no assurance that the staff of
the SEC would make a similar determination with respect to an Exchange Offer as
in other circumstances.

     The undersigned hereby further represents to the Issuer that (i) the New
Notes to be received are being acquired in the ordinary course of business of
the person receiving such New Notes, whether or not the undersigned, (ii)
neither the undersigned nor any such other person has an arrangement or
understanding with any person to participate in the distribution of the
Outstanding Notes or the New Notes within the meaning of the Securities Act and
(iii) neither the holder nor any such other person is an "affiliate," as defined
in Rule 405 under the Securities Act, of the Issuer or any Subsidiary Guarantor
or, if it is an affiliate, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.   If the
undersigned is not a broker-dealer, the undersigned represents that it is not
engaged in, and does not intend to participate in, a distribution of New Notes.
If the undersigned is a broker-dealer that will receive New Notes for its own
account in exchange for Outstanding Notes, it represents that the New Notes are
being acquired by it as a result of market-making activities or other trading
activities and it acknowledges that it will deliver a Prospectus in connection
with any resale of such New Notes.  By so acknowledging and by delivering a
Prospectus, however, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

                                       5
<PAGE>

     The undersigned acknowledges that if the undersigned is tendering
Outstanding Notes in the Exchange Offer with the intention of participating in
any manner in a distribution of the New Notes (i) the undersigned cannot rely on
the position of the staff of the SEC set forth in the Prior No-Action Letters
and, in the absence of an exemption therefrom, must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
the resale transaction of the New Notes, in which case the registration
statement must contain the selling security holder information required by Item
507 or Item 508, as applicable, of Regulation S-K of the SEC, and (ii)  failure
to comply with such requirements in such instance could result in the
undersigned incurring liability for which the undersigned is not indemnified by
the Issuer.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Issuer to be necessary or
desirable to complete the exchange, assignment and transfer of the Outstanding
Notes tendered hereby, including the transfer of such Outstanding Notes on the
account books maintained by the DTC.

     For purposes of the Exchange Offer, the Issuer shall be deemed to have
accepted for exchange validly tendered Outstanding Notes when, as and if the
Issuer gives oral or written notice thereof to the Exchange Agent.  Any tendered
Outstanding Notes that are not accepted for exchange pursuant to the Exchange
Offer for any reason will be returned, without expense, to the undersigned at
the address shown below or at a different address as may be indicated herein

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL
         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES OR
AGENT'S MESSAGE AND BOOK-ENTRY CONFIRMATIONS.   All physically delivered
Outstanding Notes or any confirmation of a book-entry transfer to the Exchange
Agent's account at the DTC of Outstanding Notes tendered by book-entry transfer
(a "Book-entry Confirmation"), as well as a properly completed and duly executed
copy of this Letter of Transmittal or facsimile hereof (or an agent's message in
lieu hereof), and any other documents required by this Letter of Transmittal
must be received by the Exchange Agent at its address set forth herein on or
prior to 5:00 p.m., New York City time, on the Expiration Date for the Exchange
Offer, or the tendering holder must comply with the guaranteed delivery
procedures set forth below.  Outstanding Notes tendered hereby must be in
denominations of principal amount of $1,000 and any integral multiple thereof.
THE METHOD OF DELIVERY OF THE TENDERED OUTSTANDING NOTES, THIS LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE
EXCHANGE AGENT.  INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE HOLDER
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ENSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE ISSUER.

     All questions as to the validity, form, eligibility (including time of
receipt) or acceptance of tendered Outstanding Notes and withdrawal of tendered
Outstanding Notes will be determined by the Issuer in its sole discretion, which
determination will be final and binding.  The Issuer reserves the absolute right
to reject any and all Outstanding Notes not properly tendered or any Outstanding
Notes the Issuer's acceptance of which would, in the opinion of counsel for the
Issuer, be unlawful.  The Issuer also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Outstanding Notes.  The
Issuer's interpretation of the terms and conditions of an Exchange Offer
(including the instructions in this Letter of Transmittal) shall be final and
binding on all parties.  Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within such time as
the Issuer shall determine.  Neither the Issuer, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Outstanding Notes, nor shall any of
them incur any liability for failure to give such notification.  Tenders of
Outstanding Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.  Any Outstanding Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders of Outstanding Notes, unless otherwise provided
in this Letter of Transmittal, as soon as practicable following the Expiration
Date.  See "The Exchange Offers" section of the Prospectus.

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their
Outstanding Notes and (a) whose Outstanding Notes are not immediately available,
or (b) who cannot deliver their Outstanding Notes, this Letter of Transmittal or
any other documents required hereby to the Exchange Agent prior to the
applicable Expiration Date or (c) who are unable to comply with the applicable
procedures under the DTC's Automated Tender Offer Program on a timely basis,
must tender their Outstanding Notes according to the guaranteed delivery
procedures set forth in the Prospectus.  Pursuant to such procedures: (i) such
tender must be made by or through a financial institution (including most banks,
savings and loan associations and brokerage houses) that is a participant in the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Program or the Stock Exchanges Medallion Program approved by the
Securities Transfer Association Inc. (an "Eligible Institution"); (ii) prior to
the applicable Expiration Date, the Exchange Agent must have received from the
Eligible Institution a properly completed and duly executed Notice of Guaranteed
Delivery (by facsimile transmission, mail or hand delivery) or a properly
transmitted agent's message and Notice of Guaranteed Delivery setting forth the
name and address of the holder of the Outstanding Notes, the registration
number(s) of such Outstanding Notes and the total principal amount of
Outstanding Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five New York Stock Exchange trading days after such
Expiration Date, this Letter of Transmittal (or facsimile hereof or an agent's
message in lieu hereof) together with the Outstanding Notes in proper form for
transfer (or a Book-entry Confirmation) and any other documents required by this
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent; and (iii) this Letter of Transmittal (or a facsimile hereof or
an agent's message in lieu hereof) together with the certificates for all
physically tendered Outstanding Notes in proper form for transfer (or Book-entry
Confirmation, as the case may be) and all other

                                      10
<PAGE>

documents required hereby are received by the Exchange Agent within five New
York Stock Exchange trading days after such Expiration Date.

     Any holder of Outstanding Notes who wishes to tender Outstanding Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery prior to 5:00
p.m., New York City time, on the applicable Expiration Date.  Upon request of
the Exchange Agent, a Notice of Guaranteed Delivery will be sent to holders who
wish to tender their Outstanding Notes according to the guaranteed delivery
procedures set forth above.  See "The Exchange Offers--Guaranteed Delivery
Procedures" section of the prospectus.

     3.   TENDER BY HOLDER.  Only a registered holder of Outstanding Notes may
tender such Outstanding Notes in the Exchange Offer.  Any beneficial holder of
Outstanding Notes who is not the registered holder and who wishes to tender
should arrange with the registered holder to execute and deliver this Letter of
Transmittal on his behalf or must, prior to completing and executing this Letter
of Transmittal and delivering his Outstanding Notes, either make appropriate
arrangements to register ownership of the Outstanding Notes in such holder's
name or obtain a properly completed bond power from the registered holder.

     4.   PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  Tenders of Outstanding Notes will be accepted only in integral
multiples of $1,000.  If less than the entire principal amount of any
Outstanding Notes is tendered, the tendering holder should fill in the principal
amount tendered in the third column of the box entitled "Description of
Outstanding Notes Tendered" above.  The entire principal amount of Outstanding
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.  If the entire principal amount of all Outstanding
Notes is not tendered, then Outstanding Notes for the principal amount of
Outstanding Notes not tendered and New Notes issued in exchange for any
Outstanding Notes accepted will be returned to the holder as promptly as
practicable after the Outstanding Notes are accepted for exchange.

     5.   SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND
ENDORSEMENTS; MEDALLION GUARANTEE OF SIGNATURES.  If this Letter of Transmittal
(or facsimile hereof) is signed by the record holder(s) of the Outstanding Notes
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the Outstanding Notes without alteration, enlargement or
any change whatsoever.  If this Letter of Transmittal (or facsimile hereof) is
signed by a participant in the DTC, the signature must correspond with the name
as it appears on the security position listing as the holder of the Outstanding
Notes.

     If any tendered Outstanding Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered holder(s) of Outstanding Notes listed and tendered hereby and the New
Notes issued in exchange therefor are to be issued (or any untendered principal
amount of Outstanding Notes is to be reissued) to the registered holder(s), then
said holder(s) need not and should not endorse any tendered Outstanding Notes,
nor provide a separate bond power.  In any other case, such holder(s) must
either properly endorse the Outstanding Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal, with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

     If this Letter of Transmittal (or facsimile hereof) or any Outstanding
Notes or bond powers are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and, unless waived by the Issuer, evidence satisfactory to the Issuer
of their authority to act must be submitted with this Letter of Transmittal.

     NO SIGNATURE GUARANTEE IS REQUIRED IF (i) THIS LETTER OF TRANSMITTAL (OR
FACSIMILE HEREOF) IS SIGNED BY THE REGISTERED HOLDER(S) OF THE OUTSTANDING NOTES
TENDERED HEREIN (OR BY A PARTICIPANT IN THE DTC WHOSE NAME APPEARS ON A SECURITY
POSITION LISTING AS THE OWNER OF THE TENDERED OUTSTANDING NOTES) AND THE NEW
NOTES ARE TO BE ISSUED DIRECTLY TO SUCH REGISTERED HOLDER(S) (OR, IF SIGNED BY A
PARTICIPANT IN THE DTC, DEPOSITED TO SUCH PARTICIPANT'S ACCOUNT AT THE DTC) AND
NEITHER THE BOX ENTITLED "SPECIAL DELIVERY INSTRUCTIONS" NOR THE BOX

                                      11
<PAGE>

ENTITLED "SPECIAL REGISTRATION INSTRUCTIONS" HAS BEEN COMPLETED, OR (ii) SUCH
OUTSTANDING NOTES ARE TENDERED FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION. IN
ALL OTHER CASES, ALL SIGNATURES ON THIS LETTER OF TRANSMITTAL (OR FACSIMILE
HEREOF) MUST BE GUARANTEED BY AN ELIGIBLE INSTITUTION.

     6.   SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders should
indicate, in the applicable box or boxes, the name and address to which New
Notes or substitute Outstanding Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal.  In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.  Holders tendering
Outstanding Notes by book-entry transfer may request that Outstanding Notes not
exchanged be credited to such account maintained at the DTC as such noteholder
may designate hereon.  If no such instructions are given, such Outstanding Notes
not exchanged will be returned to the name and address (or account number) of
the person signing this Letter of Transmittal.

     7.   TRANSFER TAXES.  The Issuer will pay all transfer taxes, if any,
applicable to the exchange of Outstanding Notes pursuant to an Exchange Offer.
If, however, New Notes or Outstanding Notes for principal amounts not tendered
or accepted for exchange are to be delivered to, or are to be registered or
issued in the name of, any person other than the registered holder of the
Outstanding Notes tendered hereby, or if tendered Outstanding Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Outstanding Notes pursuant to an Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder.  If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with this Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder and the Exchange Agent will retain possession of an amount
of Exchange Notes with a face amount at least equal to the amount of such
transfer taxes due by such tendering holder pending receipt by the Exchange
Agent of the amount of such taxes.

     8.   TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder of any Outstanding Notes or New Notes must provide the Issuer (as payor)
with its correct taxpayer identification number ("TIN"), which, in the case of a
holder who is an individual is his or her social security number.  If the Issuer
is not provided with the correct TIN, the holder or payee may be subject to a
$50 penalty imposed by Internal Revenue Service and backup withholding of 31% on
interest payments on the New Notes.

     To prevent backup withholding, each tendering holder and each prospective
holder must provide such holder's correct TIN by completing the Substitute Form
W-9 set forth herein, certifying that the TIN provided is correct (or that such
holder is awaiting a TIN), and that (i) the holder has not been notified by the
Internal Revenue Service that such holder is subject to backup withholding as a
result of failure to report all interest or dividends or (ii) the Internal
Revenue Service has notified the holder that such holder is no longer subject to
backup withholding.  If the New Notes will be registered in more than one name
or will not be in the name of the actual owner, consult the instructions on
Internal Revenue Service Form W-9, which may be obtained from the Exchange
Agent, for information on which TIN to report.

     Certain foreign individuals and entities will not be subject to backup
withholding or information reporting if they submit a Form W-8, signed under
penalties of perjury, attesting to their foreign status.  A Form W-8 can be
obtained from the Exchange Agent.

     If such holder does not have a TIN, such holder should consult the
instructions on Form W-9 concerning applying for a TIN, check the box in Part 3
of the Substitute Form W-9, write "applied for" in lieu of its TIN and sign and
date the form and the Certificate of Awaiting Taxpayer Identification Number.
Checking this box, writing "applied for" on the form and signing such
certificate means that such holder has already applied for a TIN or that such
holder intends to apply for one in the near future.  If such holder does not
provide its TIN to the Issuer within 60 days, backup withholding will begin and
continue until such holder furnishes its TIN to the Issuer.

     The Issuer reserves the right in its sole discretion to take whatever steps
are necessary to comply with the Issuer's obligations regarding backup
withholding.

                                      12

     9.   VALIDITY OF TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt), acceptance and withdrawal of tendered
Outstanding Notes will be determined by the Issuer in its sole discretion, which
determination will be final and binding.  The Issuer reserves the absolute right
to reject any and all Outstanding Notes not properly tendered or any Outstanding
Notes the Issuer's acceptance of which might, in the opinion of the Issuer or
its counsel, be unlawful.  The Issuer also reserves the absolute right to waive
any conditions of an Exchange Offer or defects or irregularities of tenders as
to particular Outstanding Notes.  The Issuer's interpretation of the terms and
conditions of an Exchange Offer (including this Letter of Transmittal and the
instructions hereto) shall be final and binding on all parties.  Unless waived,
any defects or irregularities in connection with tenders of Outstanding Notes
must be cured within such time as the Issuer shall determine.  Neither the
Issuer, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Outstanding
Notes nor shall any of them incur any liability for failure to give such
notification.

     10.  WAIVER OF CONDITIONS.  The Issuer reserves the absolute right to
waive, in whole or part, any of the conditions to an Exchange Offer set forth in
the Prospectus.

     11.  NO CONDITIONAL TENDER.  No alternative, conditional, irregular or
contingent tender of Outstanding Notes will be accepted.

     12.  MUTILATED, LOST, STOLEN OR DESTROYED OUTSTANDING NOTES.  Any holder
whose Outstanding Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated above for further
instructions.  This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, stolen or destroyed
Outstanding Notes have been followed.

     13.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
or for additional copies of the Prospectus or this Letter of Transmittal may be
directed to the Exchange Agent at the address or telephone number set forth on
the cover page of this Letter of Transmittal.  Holders may also contact their
broker, dealer, commercial bank, trust company or other nominee for assistance
concerning an Exchange Offer.

     14.  WITHDRAWAL.  Tenders may be withdrawn only pursuant to the limited
withdrawal rights set forth in the Prospectus under the caption "The Exchange
Offers--Withdrawal of Tenders."

IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE HEREOF OR
AN AGENT'S MESSAGE IN LIEU THEREOF (TOGETHER WITH THE OUTSTANDING NOTES
DELIVERED BY BOOK-ENTRY TRANSFER OR IN ORIGINAL HARD COPY FORM) MUST BE RECEIVED
BY THE EXCHANGE AGENT, OR THE NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY
THE EXCHANGE AGENT, PRIOR TO THE EXPIRATION DATE.
