     meanings assigned to them in accordance with GAAP and, unless expressly
     provided otherwise, all determinations and computations made pursuant to
     any provision hereof shall be made in accordance with GAAP; provided that
     references to any Person and its Restricted Subsidiaries on a consolidated
     basis, and any calculations of amounts with respect to any Person and its
     Restricted Subsidiaries on a consolidated basis, shall refer to such Person
     and all its Restricted Subsidiaries, whether or not such Restricted
     Subsidiaries would be accounted for as consolidated subsidiaries on such
     Person's financial statements prepared in accordance with GAAP;

          (d)  the words "herein," "hereof" and "hereunder" and other words of
     similar import refer to this Indenture as a whole and not to any particular
     Article, Section or other subdivision;

          (f)  the words "include," "included" and "including" as used herein

     Section 1.04.  Incorporation by Reference of TIA. Whenever this Indenture
refers to a provision of the TIA, the provision is incorporated by reference in
and made a part of this Indenture. This Indenture is subject to the mandatory
provisions of the TIA, which are incorporated by reference in and made a part of
this Indenture. Any terms incorporated by reference in this Indenture that are
defined by the TIA, defined by any TIA reference to another statute or defined
by SEC rule under the TIA, have the meanings so assigned to them therein. The
following TIA terms have the following meanings:

     "indenture securities" means the Notes.

     "indenture security holder" means a Holder or Noteholders.

     "indenture to be qualified" means this Indenture.

     "indenture trustee" or "institutional trustee" means the Trustee.

     "obligor" on the indenture securities means the Company, Equistar Funding

     Section 1.05.  Conflict with TIA. If any provision hereof limits, qualifies
or conflicts with a provision of the TIA that is required under the TIA to be a
part of and govern this

                                       29
<PAGE>

Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the TIA that may be so modified
or excluded, the latter provision shall be deemed (a) to apply to this Indenture
as so modified or (b) to be excluded, as the case may be.

     Section 1.06.  Compliance Certificates and Opinions. Upon any application
or request by an Issuer or by any other obligor upon the Notes to the Trustee to
take any action under any provision of this Indenture, such Issuer or other
obligor upon the Notes, as the case may be, shall furnish to the Trustee such
certificates and opinions as may be required under the TIA. Each such
certificate or opinion shall be given in the form of one or more Officers'
Certificates, if to be given by Officers, or an Opinion of Counsel, if to be
given by counsel, and shall comply with the requirements of the TIA and any
other requirements set forth in this Indenture. Notwithstanding the foregoing,
in the case of any such request or application as to which the furnishing of any
Officers' Certificate or Opinion of Counsel is specifically required by any
provision of this Indenture relating to such particular request or application,
no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (except for certificates provided for in
Section 4.05) shall include:
        ----

          (a)  a statement that the individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (b)  a brief statement as to the nature and scope of the examination
     or investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (c)  a statement that, in the opinion of such individual, he or she
     made such examination or investigation as is necessary to enable him or her
     to express an informed opinion as to whether or not such covenant or
     condition has been complied with; and

          (d)  a statement as to whether, in the opinion of such individual,
     such condition or covenant has been complied with.

     Section 1.07.  Form of Documents Delivered to Trustee. In any case where
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
information with respect to such

                                       30
<PAGE>

factual matters is in the possession of the Issuers, unless such counsel knows
that the certificate or opinion or representations with respect to such matters
are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
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 Issuers. 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 Issuers 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 Issuers 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 Issuers 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 Issuers 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

                                       31
<PAGE>

     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 Issuers 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 Issuers, at their 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 Issuers, shall cause notice of such
     record date, the proposed action by Holders and the applicable Expiration
     Date to be given to the Issuers 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
     Issuers 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.

                                       32
<PAGE>

          (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 Issuers. 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 Issuers 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 Issuers by the Trustee, or

     (b)  the Issuers 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 900 Louisiana, Houston, Texas
77002, Attention: Stephen Massad, Esq. (facsimile: (713) 229-1522), or at any
other address previously furnished in writing to the Trustee by the Issuers.

     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 each Issuer shall bind its respective successors and assigns,
whether so expressed or not.

                                       33
<PAGE>

     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, EACH ISSUER,
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,
Stockholders and Partners. No director, officer, employee, incorporator,
partner, member of the Partnership Governance Committee or holder of Capital
Stock of either Issuer or any Subsidiary Guarantor, as such, will have any
liability for any obligations of the Issuers and the Subsidiary Guarantors under
the Notes, the Subsidiary Guarantees, or the Indenture or for any claim based
on, in respect of, or by reason of, such obligations. Each holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes.

     Section 1.18.  Exhibits. All exhibits 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.

                                  Note Forms

     Section 2.01.  Forms Generally. The Notes and the Trustee's certificate of
authentication relating thereto shall be in substantially the forms set forth,
or referenced, in Exhibit A annexed hereto and in this Article 2. The Notes may
have such appropriate insertions, omissions, substitutions, notations, legends,
endorsements, identifications and other variations as are required or permitted
by law, stock exchange rule or depository rule or usage, the governing
instruments of either Issuer, agreements to which either Issuer is subject, if
any, or other customary usage, or as may consistently herewith be determined by
the Officers of the Issuers executing such Notes, as evidenced by such execution
(provided always that any such notation, legend, endorsement, identification or
variation is in a form acceptable to the Trustee and the Issuers). Each Note
shall be dated the date of its authentication.

     Initial Notes and any Additional Notes offered and sold in reliance on Rule
144A under the Securities Act shall be issued initially in the form of one or
more permanent global Notes in substantially the form set forth in Exhibit A and
shall contain the legends set forth in Section 2.03(a) and (b) (the "U.S. Global
Notes"), registered in the name of the nominee of the Depositary, deposited with
the Trustee, as custodian for the Depositary or its nominee, duly executed by
each Issuer and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount of the U.S. Global Notes may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for the Depositary or its nominee, as provided in Sections 3.13 and
3.14.

     Initial Notes and any Initial Additional Notes offered and sold in offshore
transactions in reliance on Regulation S under the Securities Act shall be
issued initially in the form of a single temporary global Note in substantially
the form set forth in Exhibit A and containing each of the legends set forth in
Section 2.03 (the "Temporary Offshore Global Note"), registered in the name of
the nominee of the Depositary, deposited with the Trustee, as custodian for the
Depositary or its nominee, duly executed by each Issuer and authenticated by the
Trustee as hereinafter provided. At any time following termination of the
Restricted Period (the "Offshore Note Exchange Date"), upon receipt by the
Trustee and the Issuers of a certificate substantially in the form set forth in
Exhibit C hereto, a single permanent global Note substantially in the form of
Exhibit A hereto and containing the legend set forth in Section 2.03(b) (the
"Permanent Offshore Global Note," and together with the Temporary Offshore
Global Note, the "Offshore Global Note") duly executed by each Issuer and
authenticated by the Trustee as hereinafter provided shall be deposited with the
Trustee, as custodian for the Depositary, and the Registrar shall reflect on its
books and records the date and a decrease in the principal amount of the
Temporary Offshore Global Note in an amount equal to the principal amount of the
beneficial interest in the Temporary Offshore Global Note transferred. Prior to
the Offshore Note Exchange Date and receipt of the certificate referred to
above, beneficial interests in a Temporary Offshore Global Note may be held only
through Euroclear or Clearstream. The aggregate principal amount of the Offshore
Global Note may from time to time be increased or decreased by adjustments made
on the records of the Trustee, as custodian for the Depositary for the Offshore
Global Note as provided in Sections 3.13 and 3.14.

                                       35
<PAGE>

     Initial Notes and any Initial Additional Notes issued in exchange for or
upon transfer of beneficial interests in the U.S. Global Note or the Permanent
Offshore Global Note pursuant to Section 3.13 shall be in the form of permanent
certificated Notes in substantially the form set forth in Exhibit A containing
the Private Placement Legend as set forth in Section 2.03 (the "U.S. Physical
Notes"), or in the form of permanent certificated Notes substantially in the
form set forth in Exhibit A (the "Offshore Physical Notes"), respectively, as
hereinafter provided. No Offshore Physical Notes may be issued until expiration
of the applicable Restricted Period and receipt by the Issuers and the Trustee
from the (x) proposed transferor of a certificate substantially in the form set
forth in Exhibit D or (y) holder of a beneficial interest being exchanged, of
certification that such holder is a non-U.S. person (within the meaning of
Regulation S under the Securities Act) or a U.S. person who acquired such
interest in a transaction exempt from the registration requirements of the
Securities Act (in which case a U.S. Physical Note shall be issued).

     Initial Additional Notes offered and sold in reliance on any exemption
under the Securities Act other than Regulation S and Rule 144A thereunder shall
be issued in the form of U.S. Physical Notes and shall contain the Private
Placement Legend as set forth in Section 2.03.

     The Offshore Physical Notes and the U.S. Physical Notes, together with any
other certificated notes in registered form, are sometimes collectively herein
referred to as the "Physical Notes." The U.S. Global Note and the Offshore
Global Note, together with any other certificated notes in registered global
form, are sometimes collectively referred to as the "Global Notes."

     Exchange Notes shall be issued substantially in the form set forth in
Exhibit A and, subject to Section 3.13, shall be in the form of one or more
Global Notes.

     Additional Dividend Notes issued in respect of any Notes shall be issued
substantially in the form set forth in Exhibit A and shall be issued in the same
form as the Notes in respect of which they are issued. Additional Dividend Notes
shall bear the same legends, including the Private Placement Legend, as the
Notes in respect of which such Additional Dividend Notes are issued. The Issuers
shall take all required steps to ensure that any Additional Dividend Notes
issued in respect of Notes that are not Restricted Securities or required by
applicable law to bear the Private Placement Legend shall not, and shall not be
required by applicable law to, be Restricted Securities or bear the Private
Placement Legend (including without limitation through the maintenance of an
effective shelf registration statement, if required).

     Section 2.02.  Form of Trustee' Certificate of Authentication. The
Trustee's certificate of authentication shall be in substantially the following
form:

     This is one of the Notes referred to in the within-mentioned Indenture.

     If an appointment of an Authenticating Agent is made pursuant to Section
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

                                   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 $700,000,000 (plus any Additional Dividend Notes issued in
respect thereof pursuant to Section 4.08), but may be increased, subject to
compliance with the covenants contained in Article 4 below and the conditions
set forth in Section 3.03. The Initial Notes will be issued in an aggregate
principal amount of $700,000,000 plus the aggregate amount of any Additional
Dividend Notes issued in respect thereof. 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 Issuers
may issue Additional Notes hereunder and the Issuers may be required to issue
Additional Dividend Notes from time to time. Initial Additional Notes (including
any Exchange Notes issued in exchange therefor) and Additional Dividend 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.

                                       39
<PAGE>

     The Notes shall be known and designated as the "10 1/8% Senior Notes Due
2008" of the Issuers. The final Stated Maturity of the Notes shall be September
1, 2008. Interest on the Outstanding principal amount of Notes will accrue,
subject to Section 3.11, at the rate of 10 1/8% per annum and will be payable
semiannually in arrears on March 1 and September 1 in each year, commencing on
March 1, 2002, to Holders of record at the close of business on the immediately
preceding February 15, and August 15, respectively (each such February 15 and
August 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 August 24, 2001, and interest on any
Additional Notes and Additional Dividend 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, from August 24,
2001; 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 Issuers will pay interest on overdue
principal and, to the extent lawful, on overdue installments of interest
(including interest to be paid in the form of Additional Dividend Notes) and
overdue amounts of 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 such
other office or agency of the Issuers maintained for that purpose (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 each Issuer by two Officers of such Issuer. The
signature of such Officers 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 an Issuer shall bind such Issuer, 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 Issuers may deliver Notes executed by the Issuers to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes (other than Additional Dividend Notes) for original issue in the aggregate
principal amount not to exceed $700,000,000 and (ii) Additional Notes (other
than Additional Dividend Notes) from time to time for original issue in
aggregate principal amounts specified by the Issuers, (iii) Exchange Notes from
time to time for issue in exchange for a like principal amount of Initial Notes
or Initial Additional Notes (including Additional Dividend Notes), and (iv) to
the extent required by Section 4.08, Additional Dividend

                                       40
<PAGE>

Notes in respect thereof from time to time for original issue in an aggregate
principal amount specified by the Issuers, in each case specified in clauses (i)
through (iv) above, upon a written order of the Issuers in the form of an
Officers' Certificate executed by two Officers of each Issuer (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 Officers' 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,
Exchange Notes and/or Additional Dividend Notes, that, in the case of Additional
Notes, the issuance of such 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 Issuers 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 Issuers 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
Issuers consider appropriate for temporary Notes. If temporary Notes are issued,
the Issuers 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 Issuers in a Place of Payment, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Issuers 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 Issuers 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 Issuers 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
Issuers in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law,

                                       41
<PAGE>

the Issuers 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 Issuers 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 Officers' 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 Issuers, 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 Issuers or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Issuers 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 Issuers 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 Issuers and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b) there is delivered to the Issuers 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 Issuers or the Trustee that such Note has been acquired
by a bona fide purchaser, the Issuers 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 Issuers in their discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Issuers may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed

                                       42
<PAGE>

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 each Issuer, 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; provided that interest payable in the form of
Additional Dividend Notes 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
Notice Date for such interest specified in Section 4.08.

     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 Issuers, as
provided in 3.07(a) or 3.07(b) below:

          (a)  The Issuers 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 Issuers 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 Issuers 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 Issuers of such
     Special Record Date and, in the name and at the expense of the Issuers,
     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

                                       43
<PAGE>

     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 Issuers 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 Issuers
     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 Issuers, the Trustee and any agent of any
Issuer 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 Issuers, the Trustee or any agent of
any of them 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 Issuers may at any time deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder that the Issuers 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 Issuers 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 Issuers 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 Issuers 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

                                       44
<PAGE>

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 Issuers 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. Neither
Issuer 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 Issuers, the Trustee and any agent of the
Issuers or the Trustee as the absolute owner of such Global Note for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Issuers, the Trustee or any agent of the Issuers 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) as required in connection
with transfers of interests therein pursuant to Section 3.14(b) or 3.14(g) or as
may be required by the Issuers or the Trustee in connection with transfers
pursuant to Section 3.14(i), and (ii) that U.S. Physical Notes or, subject to
Section 3.14(h), Offshore Physical Notes shall be transferred to all beneficial
owners in exchange for their beneficial interests in the U.S. Global Note or the
Offshore Global Note, respectively, in the event that (A) the Depositary
notifies the Issuers that it is unwilling or unable to continue as Depositary
for the applicable Global Note and a successor depositary is not appointed by
the Issuers within 90 days or (B) an Event of Default has occurred and is
continuing and the Registrar has received a request from the Depositary. In
addition, beneficial interests in a Global Note may be exchanged for Physical
Notes upon request but only upon at least 20 days' prior written notice given to
the Trustee by or on behalf of the Depository in accordance with customary
procedures. 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 this Section 3.13(b), the Registrar shall record on its books and

                                       45
<PAGE>

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 Issuers 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 this
paragraph (b), the applicable Global Note shall be deemed to be surrendered to
the Trustee for cancellation, and the Issuers 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 U.S. Physical Notes (in
the case of the U.S. Global Note) or Offshore Physical Notes (in the case of the
Offshore Global Note), as the case may be, 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)  Each Issuer, any other obligor upon the Notes and the Trustee, in the
discretion of any of them, may treat as the Act of a Holder any instrument or

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 (or,
with respect to interest required to be paid pursuant to Section 4.08,
Additional Dividend Notes in the requisite principal amount, duly issued,
authenticated and delivered in accordance with this Indenture) designated for
and sufficient to pay the installment.

     (b)  Other than payments in the form of Additional Dividend Notes, payments

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 Issuers
will make all payments of principal, premium, if any, interest and Liquidated

an office or agency in the United States 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 Issuers in respect of the Notes and
this Indenture may be served. The Issuers 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 Issuers 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 Issuers hereby designates the
Corporate Trust Office as an initial Place of Payment and as such office of the
Issuers, 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 either Issuer
shall at any time act as the Paying Agent, the Issuers 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 their action or failure
so to act.

     If neither Issuer is acting as the Paying Agent, the Issuers 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,

                                       52
<PAGE>

and (unless such Paying Agent is the Trustee) the Issuers will promptly notify
the Trustee of their action or failure so to act.

     If neither Issuer is acting as the Paying Agent, the Issuers 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 Issuers (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 Issuers may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Issuer
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
an Issuer 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 such Issuer or 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
either Issuer, 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 Issuers upon an Issuer Request, or (if then held
by an Issuer) shall be discharged from such trust; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Issuers for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Issuers as trustee
thereof, shall thereupon cease.

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 or Preferred Stock had been issued, as the case may be, at
the beginning of such four-quarter period, with any letters of credit and
bankers' acceptances being deemed to have an aggregate principal amount of
Indebtedness equal to the maximum amount available thereunder.

     The foregoing provisions will not apply to:

          (i)   the incurrence by the Company of Indebtedness pursuant to the
     Credit Facility in an aggregate principal amount at any time outstanding
     not to exceed an amount equal to $800.0 million less the aggregate
     principal 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 Credit Facility) applied to
     (a) repay loans (other than revolving credit loans) outstanding thereunder
     or (b) permanently reduce the revolving credit commitments thereunder (and
     the incurrence by its Subsidiaries of Guarantees thereof); provided that,
     if the aggregate principal amount of Indebtedness pursuant to the Credit
     Facility permitted to be incurred hereby is reduced as a result of any
     mandatory repayment made in connection with the Company's entry into a
     Receivables Facility, then such aggregate principal amount permitted to be
     incurred shall be increased by the amount of such previous reduction if and
     when such Receivables Facility is terminated;

          (ii)  the incurrence by the Company and the Subsidiary Guarantors of
     Indebtedness represented by the Notes (including any Additional Dividend
     Notes but not any Additional Notes), and 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), (v) through (xii) or (xiv) 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) 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 (1) if the
     Company or any Subsidiary Guarantor is

                                       55

     the obligor on such Indebtedness, such Indebtedness is expressly
     subordinated by its terms 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 (2)(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;

          (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 or any receivable or liability to
     which such Hedging Obligation relates or (B) managing fluctuations in the
     price or cost of raw materials, manufactured products or related
     commodities; provided that such obligations are entered into in the
     ordinary course of business to hedge or mitigate risks to which the Company
     or any Restricted Subsidiary is exposed in the conduct of its business or
     the management of its liabilities (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;

          (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 accreted value, as applicable) 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 $25 million;

                                       56

          (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 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 the
     aggregate principal amount (or accreted value, as applicable) of which,
     together with all other Indebtedness at the time outstanding and incurred
     in reliance upon this clause (xi), does not exceed $10 million;

          (xii)  the Guarantee by the Company or 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 (including giving pro forma effect to the applicable transaction
     related thereto);

          (xiv)  the incurrence by Equistar Funding of Indebtedness as a co-
     issuer of Indebtedness of the Company that was permitted to be incurred by
     another provision of this covenant;

          (xv)   the incurrence of Indebtedness represented by industrial

     Stock at the time outstanding and incurred in reliance on this clause
     (xvi), does not exceed $100 million.

     (b)  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 (i)
through (xvi) above or is entitled to be incurred pursuant to the first
paragraph of this covenant, 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 the first paragraph hereof, as the case
may be, designated by the Company. The

                                       57
<PAGE>

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.

     (c) The amount of Indebtedness outstanding under the Credit Facility for
purposes of clause (i) of the second paragraph of Section 4.06(a) shall exclude
                                                          -------
any amounts paid as interest-in-kind in connection with a Permitted Dividend.

     Section 4.07. Limitation on Restricted Payments. The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly:

     (1) declare or pay any dividend or make any distribution on account of the
         Company's or any of its Restricted Subsidiaries' Equity Interests,
         other than :

          (x) dividends or distributions payable in Qualified Equity Interests
     of the Company,

          (y) dividends or distributions payable to the Company or any
     Restricted Subsidiary of the Company, and

          (z) Permitted Dividends;

     (2) purchase, redeem or otherwise acquire or retire for value any Equity
         Interests of the Company or any Affiliate of the Company that controls
         the Company, other than any such Equity Interests owned by the Company
         or any of its Restricted Subsidiaries;

     (3) make any principal payment on, or purchase, redeem, defease or
         otherwise acquire or retire for value any Indebtedness ("Subordinated
         Debt") of the Company or any Restricted Subsidiary that is subordinated
         by its terms to the Notes or the Subsidiary Guarantees, as applicable,
         other than Indebtedness owed to the Company or any Restricted
         Subsidiary or to Lyondell, except, in each case, payment of interest or
         principal at Stated Maturity; or

     (4) make any Restricted Investment;

(all such payments and other actions set forth in clauses (1) through (4) above
being collectively referred to as "Restricted Payments"), unless, at the time of
and after giving effect to such Restricted Payment (the amount of any such
Restricted Payment, if other than cash, shall be the fair market value (as
conclusively evidenced by a resolution of the Partnership Governance Committee)
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 statements have been filed with the SEC
     pursuant to Section 4.04 immediately preceding the date of such Restricted
     Payment, have been permitted to incur at least $1.00 of additional

                                       58
<PAGE>

     Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
     the first paragraph of Section 4.06(a) and

          (c) such Restricted Payment, together with the aggregate of all other
     Restricted Payments and Permitted Dividends made by the Company and its
     Restricted Subsidiaries on or after the Issue Date (excluding Restricted
     Payments permitted by clauses (b) (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),
     (c), (d), (e), (g) and (h) of the next succeeding paragraph) and 50% of any
     Restricted Payments permitted by clause (f) of the next succeeding
     paragraph, 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 October 1, 2001, 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 or if the
          proceeds are used to make a Permitted Investment of the type described
          in clause (e) of the definition thereof) 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 clause (f) or
          (i) below, that was made after the Issue Date is sold for cash or
          otherwise liquidated, repaid or otherwise reduced, including by way of
          dividend or distribution (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 than a
          Restricted Investment permitted to be made pursuant to

                                       59
<PAGE>

          clause (f) or (i) below, previously made after the Issue Date by the
          Company or any Restricted Subsidiary in such Unrestricted Subsidiary.

   The foregoing provisions will not prohibit the following Restricted Payments
set forth below:

          (a)   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;

          (b)   dividends or distributions by any Restricted Subsidiary of the
     Company payable (x) to all holders of a class of Capital Stock of such

     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;

          (c)   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;

          (d)   the redemption, repurchase, retirement or other acquisition of
     any Equity Interests of the Company, any Affiliate of the Company, or any
     Joint Venture (or the acquisition of any outstanding Equity Interests of
     any Person the majority of whose assets are Equity Interests in the Company
     or 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 the preceding paragraph;

          (e)   the defeasance, redemption or repurchase of Subordinated Debt
     with the net cash proceeds from an incurrence of Permitted Refinancing or
     in exchange for or out of the net cash proceeds from the substantially

     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 the preceding paragraph;

          (f)   Restricted Investments in any Joint Venture made during any
     fiscal year of the Company or within 45 days after the end of such fiscal
     year in amounts that, together with all other Restricted Investments made
     in such Joint Venture in respect of such fiscal year in reliance on this
     clause (f) during such fiscal year or within 45 days after the end of such
     fiscal year, do not exceed the amount of dividends or distributions
     previously paid in respect of such fiscal year to the Company or any
     Restricted Subsidiary by such Joint Venture; provided that no Default or
     Event of Default shall have occurred and be continuing after giving effect
     to such Restricted Payment;

                                       60

          (g)   distributions or payments of Receivables Fees;

          (h)   distributions by any Restricted Subsidiary or Joint Venture of
     chemicals to a holder of Capital Stock of such Restricted Subsidiary or
     Joint Venture if such distributions are made pursuant to a provision in a
     joint venture agreement or other arrangement entered into a connection with
     the establishment of such Joint Venture or Restricted Subsidiary that
     requires such holder to pay a price for such chemicals equal to that which
     would be paid in a comparable transaction negotiated on an arms-length
     basis (or pursuant to a provision that imposes a substantially equivalent
     requirement);

          (i)   any other Restricted Payment which, together with all other
     Restricted Payments made pursuant to this clause (i) on or after the Issue
     Date, does not exceed $25 million (after giving effect to any reductions in
     the aggregate amount of such Investments made pursuant to this clause (i)
     as a result of the disposition thereof, including through liquidation,
     repayment or other reduction, including by way of dividend or distribution,
     for cash, as set forth in clause (c)(iii) above, the aggregate amount of
     such reductions not to exceed the aggregate amount of such Investments
     outstanding and previously made pursuant to this clause (i)), provided that
     no Default or Event of Default shall have occurred and be continuing after
     giving effect to such Restricted Payment; and

          (j)   the repurchase of any Subordinated Debt at a purchase price not
     greater than 101% of the principal amount thereof in the event of (x) a
     change of control pursuant to a provision no more favorable to the holders
     thereof than Section 4.13 or (y) an Asset Sale (pursuant to a provision no
                          ----
     more favorable to the holders thereof than Section 4.10); provided that,
                                                        ----
     (1) in each case, prior to such repurchase the Company has made a Change of
     Control Offer or Asset Sale Offer, as applicable, and repurchased all Notes
     that were validly tendered for payment in connection with such Change of
     Control Offer or Asset Sale Offer and (2) no Default or Event of Default
     shall have occurred and be continuing after giving effect to such
     Restricted Payment.

  The Partnership Governance Committee 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 under
the first paragraph of this covenant (except to the extent such Investments were
repaid in cash). All such outstanding Investments 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 Partnership
Governance Committee. 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.

     Section 4.08. Additional Interest upon Payment of Permitted Dividends. (a)
The Company shall provide public notice of its intent to pay a Permitted
Dividend which would require the issuance of Additional Dividend Notes by means
of a press release on a date that is not more than twenty-one days or less than
fourteen days prior to the date of any scheduled payment of any such Permitted
Dividend (a "Notice Date"). Such notice shall provide the date of the Permitted
Dividend and the amount of additional interest that will be paid on such date
pursuant to clause (b) below.

     (b)   If the Company makes a Permitted Dividend and the Company's Fixed
Charge Coverage Ratio calculated (on a pro forma basis as described in the
following sentence) on the Dividend Payment Date would have been less than 1.75
to 1, then the Issuers shall, on the date when the Company makes such Permitted
Dividend (the "Dividend Payment Date"), pay each Holder of record on the Notice
Date immediately prior to the date of such payment, as additional interest, an
amount equal to the Additional Interest Amount. For this purpose, the
calculation shall give pro forma effect to any Indebtedness, Disqualified Stock
or Preferred Stock incurred or contemplated to be incurred or any asset sold or
contemplated to be sold, in each case to finance such Permitted Dividend as if
such incurrence or sale 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 pursuant to Section 4.04 immediately preceding the Dividend Payment
Date.

     (c)   Notwithstanding the foregoing, the Issuers shall not be required to
make any additional interest payment with respect to a Permitted Dividend made
on any Dividend Payment Date (the "current date") if the Company has made an
additional interest payment with respect to another Permitted Dividend on a
Dividend Payment Date that occurred within 90 days prior to the current date.

     (d)   Any such interest payable pursuant to this Section shall be paid by
the Issuers in the form of additional Notes ("Additional Dividend Notes") that
are identical in all respects to the Notes with respect to which such Additional
Dividend Notes are issued. Interest on such Additional Dividend Notes shall
accrue from the most recent interest payment date prior to the Dividend Payment
Date or, if no interest has been paid on the Notes, from the Issue Date. The
Additional Dividend Notes shall be issued in an aggregate principal amount that,
together with accrued interest thereon through the Dividend Payment Date, as
determined pursuant to the foregoing sentence, will be equal to the Additional
Interest Amount required to be paid on the applicable Dividend Payment Date as
set out in clause (b) above; provided that the Issuers shall, to the extent
necessary, round up the principal amount of any Additional Dividend Note so that
the principal amount of each such Note is $1,000 or a higher $1,000 increment
thereof.

     Section 4.09. Limitation on Dividend and other Payment Restrictions
affecting Restricted Subsidiaries. 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

                                       62
<PAGE>

           (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)   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;

     (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
  resolution of the Partnership Governance Committee);

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

                                       63
<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
  resolution of the Partnership Governance Committee); and

     (m)   the 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 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 Credit Facility and related documentation as in effect on the
  Issue Date (as conclusively evidenced by a resolution of the Partnership
  Governance Committee).

  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 (m) 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.

     Section 4.10. Limitation on Sales of Assets. 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 resolution of the Partnership
Governance Committee of the Company set forth in an Officers' Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of; and (ii) at least 75% of the consideration therefor
received by the Company and/or such Restricted Subsidiary is in the form of cash
or Cash Equivalents, or 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 to the extent they are promptly converted or monetized 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.

                                       64
<PAGE>

  Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the
Company may apply such Net Proceeds, at its option, (a) to permanently repay
Indebtedness outstanding on the Issue Date (other than Indebtedness subordinated
by its terms to the Notes) with a Stated Maturity prior to the maturity of the
Notes (and to correspondingly reduce commitments with respect thereto in the
case of revolving borrowings) of the Company or any Restricted Subsidiary that
is 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 (b) to the
acquisition of Additional Assets (to the extent otherwise permitted by the
Indenture) or the making of a capital expenditure, in each case, in a Permitted
Business (or enter into a binding commitment for any such acquisition or
expenditure); 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 acquisition or expenditure 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 (a) 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 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 paragraph will be deemed to constitute
"Excess Proceeds." When the aggregate amount of Excess Proceeds under the
Indenture exceeds $25 million, the Issuers will be required to make an offer to
all holders of Notes issued under the Indenture (an "Asset Sale Offer") to
purchase the maximum principal amount of Notes and, if the Issuers are 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 a purchase 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 out in the Indenture. 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 Offers is less than the Excess
Proceeds, the Issuers 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 any
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 under the
Indenture shall be reset at zero.

     Section 4.11. Limitation on Affiliate Transactions. 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, any Partner or any Affiliate of any Partner (each of the foregoing,
an "Affiliate Transaction"), unless (1) the terms of such Affiliate Transaction
are no less favorable to the Company or such Restricted Subsidiary, as the case
may be, than those that could be obtained in

                                       65
<PAGE>

a comparable arm's-length transaction with a Person that is not an Affiliate of
the Company and (2) the Company delivers to the Trustee (a) with respect to any
Affiliate Transaction involving aggregate consideration in excess of $10
million, a resolution of the Partnership Governance Committee set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (1) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Partnership Governance Committee
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) 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;

          (iv)  transactions in the ordinary course of business between the
     Company or any of its Restricted Subsidiaries and any Partner or Affiliate
     of any Partner, provided that, with respect to any such Affiliate
     Transaction involving aggregate consideration in excess of $25 million,
     such Affiliate Transaction complies with clause (1) above and has been
     approved by the Partnership Governance Committee, including a majority of
     the disinterested members (if any);

          (v)   sales (including a sale in exchange for a promissory Note of or
     equity interest in such Accounts Receivable Subsidiary) of accounts
     receivable, related assets 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;

          (vi)  transactions pursuant to any contract or agreement in effect on
     the Issue Date, 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 in any material respect than the contract or
     agreement as in effect on the Issue Date (as conclusively evidenced by a
     resolution of the Partnership Governance Committee);

          (vii) any transaction or series of transactions between the Company or
     any Restricted Subsidiary and any of their Joint Ventures, provided that
     (i) such transaction or series of transactions is in the ordinary course of
     business between the Company or such Restricted Subsidiary and such Joint
     Venture, and (ii) with respect to any such Affiliate Transaction involving
     aggregate consideration in excess of $25 million, such Affiliate
     Transaction complies with clause (1) above and such Affiliate Transaction
     has been

                                       66
<PAGE>

     approved by the Partnership Governance Committee, including a majority of
     the disinterested members (if any); and

          (viii) any Restricted Payment of the type described in clause (1) or
          (2) of the first paragraph of Section 4.07 and any Permitted Dividend;

in each case, shall not be deemed to be Affiliate Transactions and therefore
(except as otherwise specified in such clauses) not subject to the requirements
of clauses (1) and (2) of the initial paragraph above.

     Section 4.12. 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, on any asset
now owned or hereafter acquired, or any income or profits therefrom, unless all
payments due under the Indenture and the Notes 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
secured by a Lien.

     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 Issuers 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 Issuers will mail, or at the Issuers'
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 Issuers 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 Issuers 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
Officers' Certificate stating the aggregate principal amount of Notes or
portions thereof being purchased by the Issuers.

   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

                                       67
<PAGE>

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 Issuers 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 otherwise required to be made by the Issuers 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 Lease-Back Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Lease-Back 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 Lease-Back Transaction
          pursuant to Section 4.06 (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 4.12 without securing the Notes; and

          (b)    the gross cash proceeds of such Sale and Lease-Back Transaction
     are at least equal to the fair market value (as conclusively determined by
     the Partnership Governance Committee) of the property that is the subject
     of such Sale and Lease-Back 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 and related
assets 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. Limitation on Business Activities by Equistar Funding.
Equistar Funding may not hold any assets, become liable for any obligations or
engage in any business activities; provided that it may be a co-obligor with
respect to the Notes or any other Indebtedness issued by the Company, and may
engage in any activities directly related thereto or necessary in connection
therewith. Equistar Funding shall be a Wholly Owned Restricted Subsidiary of the
Company at all times.

     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, 4.11, 4.15, 4.16 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 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 (other than Equistar Funding), 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 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

                                       69
<PAGE>

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 ("Guaranteed 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 (b) 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) Equistar Funding. If the Guaranteed Indebtedness is
subordinated in right of payment to the Notes or any Subsidiary Guarantee, as
applicable, pursuant to a written agreement to that effect, the Guarantee of
such Guaranteed Indebtedness must be subordinated in right of payment to the
Subsidiary Guarantee to at least the extent that the Guaranteed Indebtedness is
subordinated to the Notes.

     (b)   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.

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 Person), and may exercise every right and power
of, the Company under this Indenture with the same effect as if such successor

                                       71

Person had been named as the Company herein, and the predecessor Company shall

     Subsidiary of Equistar organized and validly existing under the laws of the
     United States of America or any jurisdiction thereof (which may be the
     continuing Person as a result of such transaction) shall expressly assume,
     by a supplemental Indenture, executed and delivered to the Trustee and in
     form and substance satisfactory to the Trustee, all of the obligations of
     an Issuer under the Notes, the Indenture and the Registration Rights
     Agreement; or

          (ii)   after giving effect thereto, at least one obligor on the Notes
     shall be a corporation organized and validly existing under the laws of the
     United States of America or any jurisdiction thereof; and

          (iii)  immediately after such transaction, no Default or Event of
     Default will have occurred and be continuing.

     (b)  Upon any assumption of the obligations of Equistar Funding by any
successors as set forth above, the successor shall succeed to, and be
substituted for (so that from and after the date of such assumption, the
provisions of this Indenture referring to "Equistar Funding" shall refer instead
to the successor corporation), and may exercise every right and power of,
Equistar Funding under this Indenture with the same effect as if such successor
Person had been named as Equistar Funding herein, and the predecessor Equistar
Funding shall be released from all its obligations hereunder and under the
Notes. If, as a result of any such transaction, the Company becomes the
successor to Equistar Funding pursuant to Section 5.03(a)(ii), Section 4.17
shall cease to be in effect with respect to the Company, but Section 5.03(a)
shall continue to remain in effect with respect to the Company.

     Section 5.04. Opinion of Counsel to Trustee. The Trustee, subject to the
provisions of Sections 7.01 and 7.03, may receive an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, conveyance, sale,
transfer, lease, exchange or other disposition referred to in Section 5.01 or
5.03 complies with the applicable provisions of this Indenture.

          (5)  any default occurs under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or

     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), whether such Indebtedness or Guarantee exists on
     the Issue Date 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;

          (6)  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 days;

          (7)  a court having jurisdiction in the premises enters a decree or
     order for relief (i) in respect of the Company or any Significant
     Subsidiary in an 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 assets of the
     Company or any Significant Subsidiary or (iii) the winding up or
     liquidation of the affairs of the Company or any Significant Subsidiary
     and, in each case, such decree or order shall remain unstayed and in effect
     for a period of 60 consecutive days;

          (8)  the Company or any Significant Subsidiary (i) commences a

                                       73
<PAGE>

          (9)  except as permitted by the Indenture, any Subsidiary Guarantee
     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.

     Section 6.02. Acceleration. If an Event of Default (other than an Event of
Default specified in clause (7) or (8) of Section 6.01 that occurs with respect
                                                  ----
to any Issuer or 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 Issuers (and to
the Trustee if such notice is given by the Holders) 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 (7) or
(8) of Section 6.01 occurs with respect to any Issuer 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.

     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 Issuers
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

                                       74
<PAGE>

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.

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(1) or (2) 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 Issuers 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 Issuers (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

                                       75
<PAGE>

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, 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 Issuers 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 Issuers.

     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 each Issuer, 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

                                       76
<PAGE>

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. Each Issuer
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 such Issuer 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 such Issuer (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.

                                       77
<PAGE>

          (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
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 either Issuer 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

     statement, instrument, opinion, report, notice, request, direction,

     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 either Issuer mentioned herein
     shall be sufficiently evidenced by an Issuer Request or an Issuer Order

     Officer of such Person as having been duly adopted and being in full force
     and effect on the date of such certificate;

                                       78
<PAGE>

          (iii)     whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon the Officers' Certificates of the Issuers;

          (iv)      the Trustee may consult with counsel of its selection and
     the 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;

          (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,

     bond, note, other evidence of indebtedness or other paper or document, but
     the Trustee, in its discretion, may make such further inquiry or
     investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of each
     Issuer, personally or by agent or attorney at the sole cost of such Issuer
     and shall incur no liability or additional liability of any kind by reason
     of such inquiry or investigation;

          (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;

          (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; and

          (ix)      the Trustee may request that each Issuer deliver an
     Officers' Certificate setting forth the names of the individuals and/or
     titles of officers authorized at such time to take specified actions
     pursuant to this Indenture, which Officers' Certificate may be signed by
     any person authorized to sign an Officers' Certificate, including any
     person as so authorized in any such certificate previously delivered and
     not superseded.

     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 Issuers, and neither the
Trustee nor any Authenticating Agent assumes any

                                       79
<PAGE>

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 on Form T-1 supplied to
the Issuers in connection with the registration of any Notes issued hereunder

     Section 7.06.  May Hold Notes. The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Issuers, 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.

          (a)       to pay to the Trustee from time to time such compensation as
     the Issuers 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

                                       80

     (whether asserted by either Issuer, a Holder or any other person) or
     liability in connection with the exercise or performance of any of its
     powers or duties hereunder.

     The Issuers' 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(7) or 6.01(8), the
                                                 ----       ----
expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     The Trustee shall have a lien prior to the Notes as to all property and
funds held by it hereunder for any amount owing it or any predecessor Trustee
pursuant to this Section 7.08, except with respect to funds held in trust for
the benefit of the Holders of particular Notes.

     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 any Issuer 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 $50,000,000. 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.
                        ----

          (a)       The Trustee may resign at any time by giving written notice
     thereof to the Issuers. 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.

          (b)       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 Issuers. 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

                                       81

     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 Issuers 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 Issuers 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 Issuers 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 Issuers
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 Issuers 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 Issuers. If no successor Trustee shall have been so appointed
by the Issuers 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 Issuers 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 Issuers 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 Issuers or the successor Trustee, such retiring
Trustee shall, upon payment of its charges,

                                       82
<PAGE>

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 Issuers 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 Issuers. (a)
If and when the Trustee shall be or become a creditor of either Issuer (or any
other obligor upon the Notes), the Trustee shall be subject to the provisions of
the TIA regarding the collection of claims against such Issuer (or any such
other obligor).

     Section 7.15.  Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Issuers 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 Issuers. 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.

any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03.  Execution of Amendments, Supplements or Waivers. The Trustee

     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
Issuers received by the Trustee or the Issuers, as the case may be, before the
date on which the Trustee receives an Officers' 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
Issuers 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 (x) 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. 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. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Issuers and in accordance with the specific direction of the Issuers)
request the Holder to deliver its Note to the Trustee. The Trustee shall (if
required by the Issuers and in accordance with the specific written direction of
the Issuers) place an appropriate notation on the Note about the changed terms
and return it to the Holder. Alternatively, if the Issuers or the Trustee so
determine, the Issuers 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.

                              Redemption of Notes

     Section 10.01. Right of Redemption. The Notes will be redeemable, in whole,

<PAGE>

     Section 10.03. Election to Redeem; Notice to Trustee. In case of any
redemption at the election of the Issuers of the Notes, the Issuers shall, at
least 45 days prior to the Redemption Date initially fixed by the Issuers
(unless a shorter notice shall be satisfactory to the Trustee), notify the
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 Issuers 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
by first class mail, postage prepaid, of such notice to each Holder of Notes to
be redeemed, at its registered address as recorded in the Register, not later
than 30 nor more than 60 days prior to the Redemption Date.

of such Note to receive such payment from the amounts held by the Trustee or
Paying Agent.

                             Subsidiary Guarantees

     Section 13.01. The Guarantees. Subject to the provisions of this Article
13, each Subsidiary Guarantor by execution of a supplemental indenture in the
form of Exhibit B hereto 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 Issuers under
this Indenture. Upon failure by the Issuers 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 Issuers 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;

          (c)       any release, impairment, non-perfection or invalidity of any
     direct or indirect security for any obligation of any Issuer or any
     Subsidiary Guarantor hereunder;

          (d)       any change in the corporate existence, structure or
     ownership of either Issuers, or any insolvency, bankruptcy, reorganization
     or other similar proceeding affecting either Issuer or its assets or any
     resulting release or discharge of any obligation of either Issuer 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 either Issuer, 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;

                                       95
<PAGE>

          (f)       any invalidity or unenforceability relating to or against
     either Issuer for any reason of this Indenture or any Note, or any
     provision of applicable law or regulation purporting to prohibit the
     payment by either Issuer of the principal of or interest and Liquidated
     Damages on any Note or any other amount payable by either Issuer under this
     Indenture; or

          (g)       any other act or omission to act or delay of any kind by
     either Issuer, 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 Issuers 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 Issuers under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of either
Issuer 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 either Issuer or any other Person.

     Section 13.05. Subrogation and Contribution. Upon making any payment with
respect to any obligation of the Issuers under this Article 13, the Subsidiary
                                                            --
Guarantor making such payment shall be subrogated to the rights of the payee
against the Issuers 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 Issuers 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 Issuers 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 Issuers 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 either Issuer under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of such Issuer, all
such amounts otherwise subject to acceleration under the terms of this Indenture
shall nonetheless be payable by the other Issuer and 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

                                       96
<PAGE>

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 Subsidiary Guarantee. To evidence
its Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
                                              -----
hereby agrees that 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 such supplemental
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.

     Section 13.09. Release of Guarantee. The Subsidiary Guarantee of a
Subsidiary Guarantor will terminate upon

          (1)       a sale or other disposition (including by way of
     consolidation or merger) of the Subsidiary Guarantor or the sale or
     disposition of all or substantially all the assets of the Subsidiary
     Guarantor (in each case other than to the Company or a Restricted
     Subsidiary) otherwise permitted by the Indenture,

          (2)       the cessation of the circumstances requiring the Subsidiary
     Guarantee,

          (3)       the designation in accordance with the Indenture of the
     Subsidiary Guarantor as an Unrestricted Subsidiary, or

          (4)       defeasance or discharge of the Notes, as provided in Article
     11 or Article 12.
     --            --

     Upon delivery by the Issuers to the Trustee of an Officers' Certificate and
an Opinion of Counsel to the foregoing effect, the Trustee will execute any
documents reasonably required in order to evidence the release of the Subsidiary
Guarantor from its obligations under its Subsidiary Guarantee.

     Section 13.10. Consolidation, Merger or Sale of Assets by a Subsidiary
Guarantor. No Subsidiary Guarantor may

          (i)       consolidate with or merge with or into any Person, or

                                       97
<PAGE>

          (ii)      sell, convey, transfer or dispose of, all or substantially
     all its assets as an entirety or substantially as an entirety, in one
     transaction or a series of related transactions, to any Person, or

          (iii)     permit any Person to merge with or into the Subsidiary
     Guarantor unless

                         (A)  the other Person is the Company or any Wholly
                    Owned Restricted Subsidiary of the Company that is a
                    Subsidiary Guarantor or becomes a Subsidiary Guarantor
                    concurrently with the transaction; or

                         (B)  (1) either (x) the Subsidiary Guarantor is the
                    continuing Person or (y) the resulting, surviving or
                    transferee Person expressly assumes by supplemental
                    indenture all of the obligations of the Subsidiary Guarantor
                    under its Subsidiary Guarantee; and

                         (2)  immediately after giving effect to the
                    transaction, no Default has occurred and is continuing; or

                         (C)  the transaction constitutes a sale or other
                    disposition (including by way of consolidation or merger) of
                    the Subsidiary Guarantor or the sale or disposition of all
                    or substantially all the assets of the Subsidiary Guarantor
                    (in each case other than to the Company or a Restricted
                    Subsidiary) otherwise permitted by the Indenture.

                            EQUISTAR CHEMICALS, LP

                         EQUISTAR FUNDING CORPORATION

                         10 1/8% Senior Note due 2008

     (1)  Principal and Interest. The Issuers, jointly and severally, agree to
pay the principal of this Note on September 1, 2008.

     The Issuers jointly and severally agree to pay interest on the principal
amount of this Note on each Interest Payment Date, as set forth below, at the
rate of 10 1/8% 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 March 1, 2002.

     [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated August 24, 2001, among the Issuers and the Initial
Purchasers named therein (the "Registration Rights Agreement"). In the event
that (i) the Issuers 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 Issuers 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 Issuers 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 Issuers
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 $0.25 per week per $1,000 in principal amount of Notes. The Issuers
shall not be required to pay Liquidated Damages for more than one Registration
Default at any given time. Following the cure of all Registration Defaults, the
accrual of Liquidated Damages will cease. All Liquidated Damages shall be paid
in the same manner and at the same time as the payment of interest thereon]./2/

respect thereof).

                                      A-4
<PAGE>

     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] or, if no interest has been paid, from August 24, 2001; 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.

     Under certain circumstances set forth in the Indenture, if the Company
makes any Permitted Dividend, the Issuers will be required to pay additional
interest on this Note to the holder of record on the applicable Notice Date.
Such interest shall be payable on the date of such Permitted Dividend and in an
amount equal to the Additional Interest Amount, and shall be payable in the form
of an additional note (an "Additional Dividend Note") that is identical in all
respects to this Note.

     The Issuers shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest (including interest paid in the
form of Additional Dividend Notes) 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 Issuers will pay interest (except defaulted
interest) on the principal amount of the Notes on each March 1 and September 1
to the Persons who are Holders (as reflected in the Register at the close of
business on the February 15 and August 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 Issuers will make payment to
the Holder that surrenders this Note to any Paying Agent on or after September
1, 2008.

     The Issuers 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 (other than
interest payable in the form of Additional Dividend Notes). 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 Issuers
will make all payments of principal, premium, if any, and interest and
Liquidated Damages, if any, at the office or agency maintained by the Issuers
for such purposes in The City of New York or, at the Issuers'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 on such
accrued interest for the intervening period.

     (3)  Paying Agent and Registrar. Initially, the Trustee will act as Paying
Agent and Registrar. The Issuers may change any Paying Agent or Registrar upon
written notice thereto. The Company, Equistar Funding or any Affiliate of any of
them may act as Paying Agent, Registrar or co-registrar.

     (4)  Indenture; Limitations. The Issuers issued the Notes under an
Indenture dated as of August 24, 2001 (the "Indenture"), among the Issuers and
The Bank of New York, as trustee

                                      A-5
<PAGE>

(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 senior unsecured obligations of the Issuers. The Indenture
limits the initial aggregate principal amount of the Notes to $700,000,000 but
permits the issuance of Additional Notes and Additional Dividend Notes subject
to compliance with the covenants contained in the Indenture.

     (5)  Optional Redemption. The Notes will be redeemable, in whole, at any
time, or in part, from time to time, at the option of the Issuers upon not less
than 30 nor more than 60 days' notice at a redemption price equal to the sum of
100% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the redemption date and the Make-Whole
Amount (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 (unless the Issuers fail to redeem such Notes).

     (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 Issuers 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 Issuers 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

                                      A-6
<PAGE>

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 Issuers
at their written request. After that, Holders entitled to the money must look to
the Issuers 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 either Issuer
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 Issuers will be discharged from the Indenture and
the Notes, except in certain circumstances for certain sections thereof, or (b)
to redemption or maturity, the Issuers 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 restrictive
covenants. Within 120 days after the end of each fiscal year, the Issuers must
report to the Trustee on compliance with such limitations.

     (13) Events of Default. If an Event of Default, as defined in the
Indenture, occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the Notes may declare all the Notes to be due and
payable. If a bankruptcy or insolvency default with respect to either Issuer or
any Significant Subsidiary that is a Subsidiary Guarantor occurs and is
continuing, the Notes automatically become due and payable. Holders may not
enforce the Indenture or the Notes except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes. Subject to certain limitations, Holders of a majority in
principal amount of the Notes then outstanding may direct the Trustee in its
exercise of remedies.

     (14) 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

                                      A-7
<PAGE>

indenture. Each Subsidiary Guarantor will irrevocably and unconditionally
guarantee, 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 Issuers 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.

     (15) Trustee Dealings with Issuer. 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, each Issuer and its Affiliates as if it were not the Trustee.

     (16) Authentication. This Note shall not be valid until the Trustee signs
the certificate of authentication on this Note.

     (17) Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=

to Minors Act).

     (18) 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.

charge a copy of the Indenture. Requests may be made to the Issuers, One Houston
