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 1.7. 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

                                       31

<PAGE>

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 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 1.8. 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

                                       32

<PAGE>

with respect to, the giving or making of any notice, declaration, request or
direction referred to in Section 1.08(e)(ii). If any record date is set pursuant
to this paragraph, the Holders of Outstanding Notes on such record date (or
their duly designated proxies), and no other Holders, shall be entitled to take
the relevant action, whether or not such Persons remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite
principal amount of Outstanding Notes on such record date. Nothing in this
paragraph shall be construed to prevent the 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

                                       33

<PAGE>

record date as the Expiration Date with respect thereto, subject to its right to
change the Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Expiration Date shall be later than the 180th day after the
applicable record date.

          (iv) Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Note may do so with
regard to all or any part of the principal amount of such Note or by one or more
duly appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

          Section 1.9. 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 (facsimile: (212) 815-5131), 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 L.L.P. at 910 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.

          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.

                                   Note Forms

          Section 2.1. 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

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

                                       36

<PAGE>

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.

          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,

                                       37

<PAGE>

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 2.2. 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.

                                    The Notes

          Section 3.1. Title and Terms. The aggregate principal amount of Notes
that may be authenticated and delivered and Outstanding under this Indenture is
initially limited to $450,000,000 (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 $450,000,000 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.

          The Notes shall be known and designated as the "10_% Senior Notes Due
2011" of the Issuers. The final Stated Maturity of the Notes shall be May 1,
2011. Interest on the Outstanding principal amount of Notes will accrue, subject
to Section 3.11, at the rate of 10_% per annum and will be payable semiannually
in arrears on May 1 and November 1 in each year, commencing on November 1, 2003,
to Holders of record at the close of business on the immediately preceding April
15, and October 15, respectively (each such April 15 and October 15, a "Regular
Record Date"). Interest on the Original Notes will accrue from the most recent
date to which interest has been paid or duly provided for or, if no interest has
been paid, from April 22, 2003, 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 April 22, 2003; 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 3.2. 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 3.3. 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 $450,000,000 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 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 3.4. 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

                                       42

<PAGE>

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 3.5. 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, 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.

                                       43

<PAGE>

          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 3.6. 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 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 3.7. 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:

                                       44

<PAGE>

          (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 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 3.8. 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 3.9. 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

                                       45

<PAGE>

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 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

                                       46

<PAGE>

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
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 writing of any Person that is identified by the Depositary as the owner of a
beneficial interest in the

                                       47

<PAGE>

Global Note; provided that the fact and date of the execution of such instrument
or writing is proved in accordance with Section 1.08(b).

          (e) Any U.S. Physical Note delivered in exchange for an interest in
the U.S. Global Note pursuant to paragraph (b) of this Section shall, except as
otherwise provided in Section 3.14, bear the Private Placement Legend.

          Section 3.14. Transfer Provisions. Unless and until (i) an Initial
Note or any Initial Additional Note is sold pursuant to an effective
registration statement, whether pursuant to the Registration Rights Agreement or
otherwise, (ii) an Initial Note or any Initial Additional Note is exchanged for
an Exchange Note in the Exchange Offer pursuant to an effective Registration
Statement, or (iii) the Resale Restriction Termination Date has occurred with
respect to an Initial Note or any Initial Additional Note and such Note is not
then held by an Affiliate of either Issuer, the following provisions shall apply
with respect to such Initial Note or Initial Additional Note:

          (a) General. The provisions of this Section 3.14 shall apply to all
transfers involving any Physical Note and any beneficial interest in any Global
Note. A Note that is a Restricted Security may not be transferred other than as
provided in this Section 3.14. A beneficial interest in a Global Note that is a
Restricted Security may not be exchanged for a beneficial interest in another
Global Note other than through a transfer in compliance with this Section 3.14.

          (b) Transfers to Non-QIB Institutional Accredited Investors. With
respect to the registration of any proposed transfer of a Note that is a
Restricted Security to any Institutional Accredited Investor that is not a QIB,

          (I) the Registrar shall register such transfer

                    (i) if it complies with all other applicable requirements of
          this Indenture (including Section 3.05 and Section 3.13); and

                    (ii) the proposed transferee has delivered to the Registrar
          a certificate substantially in the form of Exhibit E, and such
          transfer is in respect of an aggregate principal amount of Notes of
          not less than $100,000; and

                    (iii) if the proposed transferor is or is acting through an
          Agent Member holding a beneficial interest in a Global Note, upon
          receipt by the Registrar of written instructions given in accordance
          with the Depositary's and the Registrar's procedures; and

          (II) the Registrar shall (x) reflect on its books and records (and
make a notation on the relevant Global Note of) the date and a decrease in the
principal amount of the relevant Global Note in an amount equal to the principal
amount of the beneficial interest in the relevant Global Note to be transferred
or (y) cancel the Physical Note so transferred, and the Registrar shall deliver
to the transferee one or more Physical Notes of like tenor and amount.

                                       48

<PAGE>

          Each of the Issuers and the Trustee may require additional opinions,
certifications or other evidence as may be reasonably required to confirm that
any such proposed transfer is being made in compliance with the Securities Act
and applicable state securities laws.

          (c) Transfers to QIBs. With respect to the registration of any
proposed transfer of a Note that is a Restricted Security to a QIB,

          (I) the Registrar shall register such transfer:

                    (i) if it complies with all other applicable requirements of
          this Indenture (including Section 3.05 and Section 3.13); and

                    (ii) the proposed transferor has checked the box provided
          for on the form of such Note stating, or has otherwise certified to
          the Issuers and the Registrar in writing, that the sale has been made
          in compliance with the provisions of Rule 144A to a transferee who has
          signed the certification provided for on the form of such Note
          stating, or has otherwise certified to the Issuers and the Registrar
          in writing, that it is purchasing such Note for its own account or an
          account with respect to which it exercises sole investment discretion

          in the form of Exhibit D hereto from the proposed transferor; and

                    (iii) if the proposed transfer is to be made after the end

          Indenture (including Section 3.05 and Section 3.13); and

                    (B) if such transfer is being made by a proposed transferor

          or has otherwise certified to the Issuers and the Registrar in
          writing, that the sale has been made in compliance with the provisions
          of Rule 144; and

                    (C) if the proposed transferor or transferee is or is acting

          (g) Transfers to the Company. With respect to the registration of any
proposed transfer of a Note to the Company,

          (I) the Registrar shall register such transfer

                    (A) if it complies with all other requirements of this
          Indenture (including Section 3.05 and Section 3.13); and

                    (B) if such transfer is being made by a proposed transferor

                                       51

<PAGE>

                    (C) if the proposed transferor is or is acting through an
          Agent Member, upon receipt by the Registrar of written instructions
          given in accordance with the Depositary's and the Registrar's
          procedures; and

          (h) Interests in the Offshore Global Note prior to the Offshore Note
Exchange Date. Notwithstanding anything to the contrary contained in this
Indenture, until the Offshore Note Exchange Date occurs and appropriate
certification substantially in the form of Exhibit C is made as provided in
Section 2.01, beneficial interests in the Offshore Global Note may be held only
in or through accounts maintained at the Depositary by Euroclear or Clearstream,
and no person shall be entitled to effect any transfer or exchange that would
result in any such interest being held otherwise than in or through such an
account, and no Physical Notes may be issued in exchange therefor.

          (i) Other Transfers. The Registrar shall effect and register, upon
receipt of a written request from the Issuers to do so, a transfer not otherwise
permitted by this Section 3.14, such registration to be done in accordance with
the otherwise applicable provisions of this Section 3.14, upon the furnishing by
the proposed transferor or transferee of a written opinion of counsel (which
opinion and counsel are satisfactory to the Issuers and the Trustee) to the
effect that, and such other certifications or evidence as the Issuers may
require to confirm that, the proposed transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act and otherwise in compliance with applicable
state securities laws.

          (j) Limitation on Issuance of Physical Notes. No Physical Note shall
be exchanged for a beneficial interest in any Global Note, except in accordance
with Section 3.13 and this Section 3.14.

          (k) Execution, Authentication and Delivery of Physical Notes. In any
case in which the Registrar is required to deliver a Physical Note to a
transferee or transferor, the Issuers shall execute, and the Trustee shall
authenticate and make available for delivery, such Physical Note.

          (l) Private Placement Legend. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar
shall deliver Notes that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend,
unless (i) the requested transfer is after the relevant Resale Restriction
Termination Date with respect to such Notes, (ii) upon written request of the
Issuers after there is delivered to the Registrar an opinion of counsel (which
opinion and counsel are satisfactory to the Issuers and the Trustee) to the
effect that neither such legend nor the related restrictions on transfer are
required in order to maintain compliance

                                       52

<PAGE>

with the provisions of the Securities Act, (iii) with respect to an Offshore
Global Note, with the agreement of the Issuers on or after the Offshore Note
Exchange Date with respect to such Note, (iv) such Notes are sold or exchanged
pursuant to an effective registration statement under the Securities Act or (v)
such Notes are sold pursuant to Section 3.14(f).

          (m) General. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

          The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 3.13 or this Section 3.14
(including all Notes received for transfer pursuant to this Section 3.14). Each
Issuer shall have the right to require the Registrar to deliver to such Issuer,
at such Issuer's expense, copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

          In connection with any transfer of any Note, the Trustee, the
Registrar and the Issuers shall be entitled to receive, shall be under no duty
to inquire into, may conclusively presume the correctness of, and shall be fully
protected in relying upon the certificates, opinions and other information
referred to herein (or in the forms provided herein, attached hereto or to the
Notes, or otherwise) received from any Holder and any transferee of any Note
regarding the validity, legality and due authorization of any such transfer, the
eligibility of the transferee to receive such Note and any other facts and
circumstances related to such transfer.

          (n) Certain Additional Terms Applicable to Physical Notes. Any
transferee entitled to receive a Physical Note may request that the principal
amount thereof be evidenced by one or more Physical Notes in any authorized
denomination or denominations and the Registrar shall comply with such request
if all other transfer restrictions are satisfied.

                                    ARTICLE 4

                                    Covenants

          Section 4.1. Payment of Principal, Premium and Interest. (a) The
Issuers 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.

                                       53

<PAGE>

          (b) Other than payments in the form of Additional Dividend Notes,
payments (including principal, premium, if any, interest and Liquidated Damages,
if any) in respect of the Notes represented by the Global Notes, the Holder of
which has given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Issuers will make all payments of principal, premium, if any, interest and
Liquidated Damages, if any, at the office or agency maintained by the Issuers
referred to in Section 4.02 or, at the option of the Issuers, by mailing a check
to each such Holder's registered address. Additional Dividend Notes shall be
issued and delivered to each Holder at the Issuers' expense.

          Section 4.2. Maintenance of Office or Agency. The Issuers will
maintain 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 4.3. 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, 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

                                       54

<PAGE>

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.

          Section 4.4. SEC Reports. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes issued hereunder are outstanding,
the Company will furnish to each Trustee and the Holders of Notes (i) all
quarterly and annual financial information that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were
required to file such Forms, including a "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and, with respect to the
annual information only, a report thereon by the Company's certified independent
accountants and (ii) all current reports that would be required to be filed with
the SEC on Form 8-K if the Company were required to file such reports. In
addition, whether or not required by the rules and regulations of the SEC, the
Company will file a copy of all such information and reports with the SEC for
public availability and make such information available to securities analysts
and prospective investors upon request.

                                       55

<PAGE>

          (b) For so long as any Notes remain outstanding, the Issuers will
furnish to the Holders and to securities analysts and prospective investors,
upon their request, the information, if any, required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

          (c) All obligors on the Notes will comply with Section 314(a) of the
TIA.

          (d) Each Issuer shall promptly mail copies of all such annual reports,
information, documents and other reports provided to the Trustee pursuant to
clauses (a) and (c) hereof to the Holders at their addresses appearing in the
Register maintained by the Registrar.

          (e) Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Issuers'
compliance with any of the covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

          Section 4.5. Certificates to Trustee. (a) Each Issuer will deliver to
the Trustee within 120 days after the end of each fiscal year of the Company a
certificate from the principal executive, financial or accounting officer of
such Issuer stating that such officer has conducted or supervised a review of
the activities of the Company and its Restricted Subsidiaries and the Company's
and its Restricted Subsidiaries' performance under this Indenture and that,
based upon such review, to the best of such officers' knowledge, the Issuers
have fulfilled all obligations thereunder or, if there has been a default in the
fulfillment of any such obligation (determined without regard to any period of
grace or requirement of notice provided in this Indenture), specifying each such
default and the nature and status thereof.

          (b) Each Issuer will deliver to the Trustee, as soon as possible and
in any event within 30 days after such Issuer becomes aware of an Event of
Default or a Default, an Officers' Certificate setting forth the details of such
Event of Default or Default, and the action which such Issuer proposes to take
or has taken with respect thereto.

          (c) Each Issuer will deliver to the Trustee within 120 days after the
end of each fiscal year of the Company a written statement by such Issuer's
independent public accountants stating (i) that their audit examination has
included a review of the terms of this Indenture and the Notes as they relate to
accounting matters, and (ii) whether, in connection with their audit
examination, any Default has come to their attention and, if such a Default has
come to their attention, specifying the nature and period of the existence
thereof.

          Section 4.6. Limitation on Indebtedness. (a) On and after the Issue
Date, (x) the Company will not, and will not permit any of its Restricted
Subsidiaries to incur any Indebtedness (including Acquired Debt); (y) the
Company will not, and will not permit any of its Restricted Subsidiaries to,
issue any Disqualified Stock (including Acquired Disqualified Stock); and (z)
the Company will not permit any of its Restricted Subsidiaries

                                       56

<PAGE>

that are not Subsidiary Guarantors to issue any shares of Preferred Stock
(including Acquired Preferred Stock); provided, however, that the Company and
the Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) and
the Company and the Subsidiary Guarantors may issue shares of Disqualified Stock
(including Acquired Disqualified Stock) if the Fixed Charge Coverage Ratio for
the Company's most recently ended four full fiscal quarters for which financial
statements have been filed with the SEC pursuant to Section 4.04 immediately
preceding the date on which such additional Indebtedness is incurred or such
Disqualified Stock is issued would have been at least 2.0 to 1, determined on a
pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred or the
Disqualified Stock 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 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 after August 24, 2001 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,

          statements have been filed with the SEC pursuant to Section 4.04

          (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 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

               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

                                       60

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 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 August 24, 2001
          (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

               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

               Company or if the proceeds are used to make a Permitted
               Investment of the type described in clause (e) of the definition
               thereof) after August 24, 2001 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 August 24, 2001
               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

               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

Payments set forth below:

          of the Company payable (x) to all holders of a class of Capital Stock
          of such Restricted Subsidiary on a pro rata basis or on a basis that
          is more favorable to the Company; provided that at least 50% of such
          class of Capital Stock is held by the Company and/or one or more of

          any reductions in the aggregate amount of such Investments made
          pursuant to this clause (i) as a result of the disposition thereof,

          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.

          For the purposes of this Section 4.07, any payment made on or after
August 24, 2001 but prior to the Issue Date, shall be deemed to be a "Restricted
Payment" to the extent such payment would have been a Restricted Payment had the
Indenture been in effect at the time of such payment (and, to the extent that
any such Restricted Payment was permitted by clauses 4.07(a) through (j) above,
such Restricted Payment may be deemed by the Company to have been made pursuant
to such clause.

          Section 4.8. 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.

                                       64

<PAGE>

          (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 4.9. 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

                    (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

                                       65

<PAGE>

     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;

               (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

                                       66

<PAGE>

               (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.

          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 any 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

                                       67

<PAGE>

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 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

                                       68

<PAGE>

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 (A) 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 (B) 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 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;

                                       69

<PAGE>

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 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

                                       70

<PAGE>

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.

                                       71

          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 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

                                       72

<PAGE>

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.

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).

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.

                                    Remedies

          Section 6.1. Events of Default. Each of the following constitutes an
"Event of Default":

                    (1) default for 30 days in the payment when due of interest
          (including the issuance of Additional Dividend Notes) or Liquidated
          Damages on the Notes;

                    (2) default in payment when due of the principal of or
          premium, if any, on the Notes at maturity or otherwise;

                    (3) failure by the Issuers to comply with Section 4.10, 4.13
          or Article 5;

                    (4) failure by the Issuers for 60 days after notice by the
          Trustee or Holders of at least 25% in principal amount of the then
          outstanding Notes issued thereunder to comply with any of the other
          agreements in the Indenture or the Notes;

                    (5) any default occurs under any mortgage, indenture or
          instrument under which there may be issued or by which there may be
          secured or evidenced any Indebtedness for money borrowed by the
          Company or any of its Significant Subsidiaries (or any Indebtedness
          for money borrowed Guaranteed by the Company or any of its Significant
          Subsidiaries if the Company or a Significant Subsidiary does not
          perform its payment obligations under such Guarantee within any grace
          period provided for in the documentation governing such Guarantee),
          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

                                       76

<PAGE>

          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 voluntary case under any applicable bankruptcy, insolvency or other
          similar law now or hereafter in effect, or consents to the entry of an
          order for relief in an involuntary case under any such law, (ii)
          consents to the appointment of or taking possession by 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) effects any general assignment for the
          benefit of creditors; and

                    (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 6.2. 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 6.3. 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 6.4. 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

                                       77

<PAGE>

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 6.5. Control by Majority. The Holders of at least a majority
in aggregate principal amount of the Outstanding Notes may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee. However, the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture, that may involve the Trustee in personal liability, or that the
Trustee determines in good faith may be unduly prejudicial to the rights of
Holders not joining in the giving of such direction and may take any other
action it deems proper that is not inconsistent with any such direction received
from the Holders.

          Section 6.6. 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 6.7. 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 6.8. 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

                                       78

<PAGE>

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 6.9. 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
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.

                                       79

          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 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 7.1. Certain Duties and Responsibilities. (a) Except during
the continuance of an Event of Default,

                                       80

<PAGE>

                    (i) the Trustee need perform only those duties that are
          specifically set forth in this Indenture and no others, and no implied
          covenants or obligations shall be read into this Indenture against the
          Trustee; and

                    (ii) in the absence of bad faith on its part, the Trustee
          may conclusively rely, as to the truth of the statements and the
          correctness of the opinions expressed therein, upon certificates or
          opinions furnished to the Trustee and conforming to the requirements
          of this Indenture. However, in the case of any such certificates or
          opinions which by any provision hereof are specifically required to be
          furnished to the Trustee, the Trustee shall examine the certificates
          and opinions to determine whether or not they conform to the
          requirements of this Indenture (but need not confirm or investigate
          the accuracy of mathematical calculations or other facts stated
          therein).

          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph does not
limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts; and
(iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it
pursuant to Section 6.06.

          (d) The Trustee may refuse to perform any duty or exercise any right
or power or expend or risk its own funds or otherwise incur any financial
liability unless it receives indemnity satisfactory to it against any loss,
liability or expense.

          (e) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of
Sections 7.01 and 7.03.

          Section 7.2. 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

                                       81

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 7.01:

                    (i) the Trustee may conclusively rely and shall be protected

          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

          to it against any loss, liability or expense which might be incurred
          by it in compliance with such request or direction;

                    (vi) the Trustee shall not be bound to make any
          investigation into the facts or matters stated in any resolution,
          certificate, statement, instrument, opinion, report, notice, request,
          direction, consent, order, 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

                                       82

<PAGE>

          shall incur no liability or additional liability of any kind by reason

          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 7.4. 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 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 will
be true and accurate subject to the qualifications set forth therein. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Issuers of the Notes or the proceeds thereof.

          Section 7.5. Trustee's Disclaimer. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Issuers' use of the proceeds from the Notes, it shall not be
responsible for any statement in the offering memorandum for the Notes or in the
Indenture or the Notes (other than its certificate of authentication), the acts
of a prior Trustee hereunder, or the determination as to which beneficial owners
are entitled to receive any notices hereunder.

          Section 7.6. 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 Section 7.09 and Section 7.14, may otherwise deal with the Issuers
and their Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

          Section 7.7. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee

                                       83

<PAGE>

shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Issuers.

          Section 7.8. Compensation and Reimbursement. Each Issuer, jointly and
severally, agrees:

          (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 (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 7.9. 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,

                                       84

<PAGE>

pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section 7.10 and to the extent
permitted by the TIA, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 7.10, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

          Section 7.11. Resignation and Removal; Appointment of Successor. (a)
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 7.12.

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

          (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the 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 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

                                       85

<PAGE>

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, 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.

                                       86

<PAGE>

          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.

          request, a list of similar form and content as of a date not more than
          15 days prior to the time such list is furnished;

          (b) The Issuers will promptly notify the Trustee when any Notes are

practicable, the names and addresses of Holders contained in the most recent
list, if any, furnished to the Trustee as provided in Section 8.01 and the names
and addresses of Holders received by the Trustee in its capacity as Registrar;
provided, however, that if and so long as the Trustee shall be the Registrar,
the Register shall satisfy the requirements relating to such list. None of the
Issuers, the Trustee or any other Person shall be under any responsibility with
regard to the

                                       87

          Section 8.3. Reports by Trustee. The Trustee shall transmit to Holders
such reports concerning the Trustee and its actions under this Indenture as may

thereto. If required by Section 313(a) of the TIA, the Trustee shall, within 60
days after each May 15, following the date of this Indenture deliver to Holders

<PAGE>

                    (v) to add to the covenants of the Issuers for the benefit
          of the Holders or to surrender any right or power conferred upon the

Issuers and the Trustee may amend or supplement this Indenture or the Notes with

          premium, if any, or interest or Liquidated Damages, if any, on the
          Notes (except as set forth in Section 6.04),

<PAGE>

                    (viii) reduce the percentage or aggregate principal amount
          of outstanding Notes the consent of whose Holders is necessary for
          waiver of compliance with provisions of the Indenture or for waiver of
          Defaults,

                    (ix) modify or change any provision of the Indenture
          affecting the ranking of the Notes or the Subsidiary Guarantees in a
          manner adverse to the Holders of the Notes, or

                    (x) release any Subsidiary Guarantor from any of its
          obligations under its Subsidiary Guarantee or the Indenture other than
          in accordance with the provisions of the Indenture, or amend or modify
          any provision relating to such release.

          (c) It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          (d) After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Issuers shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,
supplement or waiver. Any failure of the Issuers to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

          Section 9.3. Execution of Amendments, Supplements or Waivers. The
Trustee shall sign any amendment, supplement or waiver authorized pursuant to
this Article 9 if the amendment, supplement or waiver does not adversely affect
the rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by each
Issuer and that such amendment, supplement or waiver is a valid and binding
agreement of each Issuer, enforceable against it in accordance with its terms
(subject to customary exceptions).

          Section 9.4. 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.

                                       90

<PAGE>

          (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 9.5. 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 9.6. 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.

          (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

          (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 10.5. Notice of Redemption. (a) Notice of redemption or

          become due and payable upon each such Note to be redeemed, and that,

          terms of this Indenture, interest and Liquidated Damages thereon shall
          cease to accrue from and after said date,

or purchased at the election of the Issuers shall be given by the Issuers or, at
the written request of the Issuers delivered at least five Business Days prior
to the date proposed for the mailing of such notice, by the Trustee in the name
and at the expense of the Issuers; provided that such notice to the Trustee may
be revoked by the Issuers by written notice delivered to the Trustee prior to
the date proposed for the mailing of the notice of such redemption to the
Holders.

          (c) The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note.

a.m., New York City time on any Redemption Date, the Issuers shall deposit with
the Trustee or with a Paying Agent (or, if an Issuer is acting as the Paying

4.03) an amount of money sufficient to pay the Redemption Price of, and any

notice, such Notes shall be paid by the Issuers at the Redemption Price.
Installments of interest and Liquidated Damages, if any, whose Interest Payment
Date is on or prior to the Redemption Date shall be payable to the Holders of
such Notes registered as such on the relevant Regular Record Dates according to
their terms and the provisions of Section 3.07.

          (b) On and after any Redemption Date, if money sufficient to pay the
Redemption Price of and any accrued and unpaid interest and Liquidated Damages
on Notes called for redemption shall have been made available in accordance with
Section 10.06, the Notes (or the portions thereof) called for redemption will

demand of and at the expense of the Issuers, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture, and each Subsidiary

the obligations of the Issuers to the Trustee under Section 7.08 and, if money
shall have been deposited with the Trustee pursuant to clause (ii) of Section
11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal (and premium, if any) and interest and Liquidated Damages on the
Notes; but such money need not be segregated from other funds except to the
extent required by law.

          Section 12.2. Legal Defeasance and Discharge. Upon the exercise by the
Issuers under Section 12.01 of the option applicable to this Section 12.02, the
Issuers shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means
that the Issuers shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this

the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully

Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Issuers in connection therewith
and with this Article 12. Subject to compliance with this Article 12, the
Issuers may exercise their option under this Section 12.02 notwithstanding the
prior exercise of their option under Section 12.03 hereof with respect to the
Notes.

          Section 12.3. Covenant Defeasance. Upon the exercise by the Issuers

shall be released from their obligations under the covenants contained in
Sections 4.06 through Section 4.17, Section 4.22 and Section 5.01(a)(iii) hereof
with respect to the Outstanding Notes, no Default under Section 6.01(5), (6) and
(9) shall thereafter constitute a Default or Event of Default and each
Subsidiary Guarantor's obligations under its Subsidiary Guarantee will terminate
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied

not Outstanding for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the

<PAGE>

consequences of any thereof) in connection with such covenants, but shall
continue to be deemed Outstanding for all other purposes hereunder. For this
purpose, such Covenant Defeasance means that, with respect to the Outstanding
Notes, the Issuers may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.01(3) or
(4), but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby.

          Section 12.4. Conditions to Legal or Covenant Defeasance. The

that Holders will not recognize income, gain or loss for Federal income tax
purposes as a result of the exercise by the Issuers of its option under this
Article 12 and will be subject to Federal income tax on the same amount and in
the same manner and at the same times as would have been the case if such
deposit, defeasance and discharge had not occurred, which Opinion of Counsel
must be based upon (and accompanied by a copy of) a ruling of the Internal
Revenue Service to the same effect unless there has been a change in applicable
Federal income tax law after the date of this Indenture such that a ruling is no
longer required or (y) a ruling directed to the Trustee received from the
Internal Revenue Service to the same effect as the aforementioned Opinion of
Counsel and (ii) an Opinion of Counsel to the effect that, as a result of the

each Issuer to the Trustee of (i) an Opinion of Counsel to the effect that,
among other things, the Holders will not recognize income, gain or loss for

at the same times as would have been the case if such deposit and defeasance had
not occurred and (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, such Issuer will not be required to

time or both would become an Event of Default, shall have occurred and be
continuing on the date of such deposit or during the period ending on the 123rd
day after the date of such deposit, and such deposit shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which either Issuer is a party or by which either Issuer is bound;

          (e) if at such time the Notes are listed on a national securities
exchange, the Issuers have delivered to the Trustee an Opinion of Counsel to the

          (f) each Issuer shall have delivered to the Trustee an Officers'
Certificate stating that the deposit made by the Issuers pursuant to their
election under Sections 12.02 or 12.03 was not made by the Issuers with the
intent of preferring the Holders over the other creditors of either Issuer with
the intent of defeating, hindering, delaying or defrauding creditors of either
Issuer or others; and

          (g) each Issuer shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Legal Defeasance under Section
12.02 or the Covenant Defeasance under Section 12.03 (as the case may be) have
been complied with as contemplated by this Section 12.04.

          Section 12.5. Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including either Issuer acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

                                       98

<PAGE>

          The Issuers shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section 12.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

          Anything in this Article 12 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuers from time to time upon the request
of the Issuers any money or U.S. Government Obligations held by it as provided
in Section 12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
12.04(a) hereof), are in excess of the amount thereof which would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

          Section 12.6. Repayment to Issuers. 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, premium, if any, or interest and Liquidated Damages
on any Note and remaining unclaimed for two years after such principal, premium,
if any, or interest and Liquidated Damages has become due and payable shall be
paid to the Issuers on its written request or (if then held by either 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 either Issuer as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense of the Issuers cause to be published once, in The New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Issuers.

          Section 12.7. Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with Section
12.02 or 12.03, as the case may be, by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the obligations of the Issuers under this Indenture and
the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.02 or 12.03 until such time as the Trustee or Paying
Agent is permitted to apply all such amounts in accordance with Section 12.02 or
12.03 hereof, as the case may be; provided, however, that, if either Issuer
makes any payment of principal of, premium, if any, or interest and Liquidated
Damages on any Note following the reinstatement of its Obligations, such Issuer
shall be subrogated to the rights of the Holder of such Note to receive such
payment from the amounts held by the Trustee or Paying Agent.

                              Subsidiary Guarantees

          Section 13.1. 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 13.2. 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;

          (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

                                      100

<PAGE>

          (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 13.3. 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 13.4. 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 13.5. 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 13.6. 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 13.7. Limits of Guarantees. Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law. To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the

                                      101

<PAGE>

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 13.8. 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 13.9. 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

                    (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

                                      102

<PAGE>

                    (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.

120th day after the deadline to file a Shelf Registration Statement pursuant to
clause (iv) above, 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, jointly and severally, 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

                                      A-4

<PAGE>

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

     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 April 22, 2003; 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 May 1 and November 1 to
the Persons who are Holders (as reflected in the Register at the close of
business on the April 15 and October 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is canceled on registration of
transfer or registration of exchange after such Regular Record Date; provided
that, with respect to the payment of principal, the Issuers will make payment to
the Holder that surrenders this Note to any Paying Agent on or after May, 2011.

     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

----------
     /2/  Include only for Initial Note(and Additional Dividend Notes issued in
          respect thereof).

                                      A-5

<PAGE>

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 April 22, 2003 (the "Indenture"), among the Issuers and The Bank of
New York, as trustee (the "Trustee"). Capitalized terms herein are used as
defined in the Indenture unless otherwise indicated. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (the "TIA"). The Notes are subject
to all such terms, and Holders are referred to the Indenture and the TIA for a
statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Note and the terms of the
Indenture, the terms of the Indenture shall control.

     The Notes are senior unsecured obligations of the Issuers. The Indenture
limits the initial aggregate principal amount of the Notes to $450,000,000 but
permits the issuance of Additional Notes and Additional Dividend Notes subject
to compliance with the covenants contained in the Indenture.

     (5) Optional Redemption. Prior to May 1, 2007, 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).

     On or after May 1, 2007, 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 the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the redemption date, if
redeemed during the twelve-month period beginning on May 1, of the following
years:

Year                  Percentage
-------------------   ----------

2007                   105.313%
2008                   102.656%
2009 and thereafter    100.000%

     If less than all the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the

                                      A-6

<PAGE>

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 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

                                      A-7

<PAGE>

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 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.
