85% of the outstanding Capital Stock or other voting interests of any Subsidiary
that was a Joint Venture on the date of its designation as an Unrestricted
Subsidiary), or (ii) at any time the Company or any Restricted Subsidiary
Guarantees any Indebtedness of such Unrestricted Subsidiary or makes any other

the Company shall be in default of such covenant). The Board of Directors of the
Company may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that such designation shall be deemed to be an incurrence
of Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (i) such Indebtedness is permitted under Section 4.06 and (ii) no

be.

     Section 1.06.  Compliance Certificates and Opinions.  Upon any application
or request by the Company or by any other obligor upon the Notes to the Trustee
to take any action under any provision of this Indenture, the Company or such
other obligor upon the Notes, as the case may be, shall furnish to the Trustee

Certificates, if to be given by an Officer, or an Opinion of Counsel, if to be
given by counsel, and shall comply with the requirements of the TIA and any
other requirements set forth in this Indenture. Notwithstanding the foregoing,
in the case of any such request or application as to which the furnishing of any
Officer's Certificate or Opinion of Counsel is specifically required by any
provision of this Indenture relating to such particular request or application,
no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or

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;

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

     Section 1.07.  Form of Documents Delivered to Trustee.  In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion with respect to some matters and one or more other such Persons as to
other matters, and any such Person may certify or give an opinion as to such
matters in one or several documents.

     Any certificate or opinion of an Officer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such Officer knows that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such certificate or opinion of counsel may
be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an Officer or Officers to the effect that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows that the certificate or opinion or
representations with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Section 1.08.  Acts of Noteholders; Record Dates.   (a)  Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such Holders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee, and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 7.01)
conclusive in favor of the Trustee, the Company and any other obligor upon the
Notes, if made in the manner provided in this Section 1.08.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership or
other entity, on behalf of such corporation or partnership or other entity, such
certificate or affidavit shall also constitute sufficient proof of such Person's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the person executing the same, may also be proved in any
other manner that the Trustee deems sufficient.

                                       30


     (c)  The ownership of Notes shall be proved by the Register.

     (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Note shall bind the Holder of every Note
issued upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done or suffered to be done by the Trustee, the Company or
any other obligor on the Notes in reliance thereon, whether or not notation of
such action is made upon such Note.

     (e)  (i) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in Section
1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date (or their duly designated proxies), and
no other Holders, shall be entitled to take the relevant action, whether or not
such Persons remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Notes on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder in the manner set forth in Section 1.10.

          (ii)  The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to join in the giving or
making of (w) any Notice of Default, (x) any declaration of acceleration
referred to in Section 6.02, (y) any request to institute proceedings referred
to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each
case with respect to Notes. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Notes on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the expense of the Company, shall cause notice of such record date,
the proposed action by Holders and the applicable

                                       31


Expiration Date to be given to the Company in writing and to each Holder in the
manner set forth in Section 1.10.

          (iii)  With respect to any record date set pursuant to this Section
1.08, the party hereto that sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Company or the
Trustee, whichever such party is not setting a record date pursuant to this
Section 1.08(e) in writing, and to each Holder in the manner set forth in
Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

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

     Section 1.09.  Notices, Etc., to Trustee and Company.  Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

     (a)  the Trustee by any Holder or by the Company or any other obligor upon
the Notes shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at the Corporate Trust
Office (telephone: (212) 815-6286; facsimile: (212) 815-5915), or at any other
address furnished in writing to the Company by the Trustee, or

     (b)  the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder if in writing and delivered in person or mailed, first-
class postage prepaid, to the Company at One Houston Center, Suite 700, 1221
McKinney, Houston, Texas 77010, Attention: General Counsel (facsimile: (713)

77002, Attention: Steve Massad, Esq. (facsimile: (713) 229-1522), or at any
other address previously furnished in writing to the Trustee by the Company.

     Section 1.10.  Notices to Holders; Waivers.  Where this Indenture provides
for notice to Holders of any event, such notice shall be deemed to have been
given upon the mailing by first class mail, postage prepaid, of such notices to
Holders at their registered addresses as recorded in the Register, not later
than the latest date, and not earlier than the earliest date, prescribed herein
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail notice of any event as
required by any provision of this Indenture, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably
withheld) shall constitute a sufficient notification for every purpose
hereunder.

Section headings herein and the Table of Contents are for convenience only and

or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 1.14.  Benefits of Indenture.  Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 1.15.  Governing Law.  THIS INDENTURE, THE NOTES AND THE SUBSIDIARY
GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY.  TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY,
THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY
THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NONEXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH
OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF

     Section 1.16. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest and Liquidated Damages, if any, or principal and premium (if any)
need not be made on such date, but may be made on the next succeeding Business
Day with the same force and

                                       33


effect as if made on the Interest Payment Date or Redemption Date, or at the
Stated Maturity.

or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

     Section 1.18.  Exhibits and Schedules.  All exhibits and schedules attached
hereto are by this reference made a part hereof with the same effect as if
herein set forth in full.

together constitute but one and the same instrument.

on the face thereof:

                                       35


THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY
STATE OR OTHER JURISDICTION, AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS
ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

(1)  REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (As defined in
     Rule 144A under the Securities Act) (A "QIB")

(2)  AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A)
     TO THE COMPANY, (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
     QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB TO WHOM
     NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A IN
     A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (C) IN A TRANSACTION
     MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT (IF
     AVAILABLE), (D) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION
     REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL,
     CERTIFICATION AND/OR OTHER INFORMATION ACCEPTABLE TO THE COMPANY AND THE
     TRUSTEE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN
     EACH CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE
     OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND

(3)  AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST
     HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER
ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING.

     (b)  Each Global Note, whether or not an Initial Note or Additional Note,
shall also bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR
THEIR AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME
AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE
TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE

                                       36


HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE
LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN
SECTIONS 3.13 AND 3.14 OF THE INDENTURE.



                                   ARTICLE 3
                                   THE NOTES

     Section 3.01.  Title and Terms.  The aggregate principal amount of Notes
that may be authenticated and delivered and Outstanding under this Indenture is
initially limited to $500,000,000, but may be increased, without limit, subject
to compliance with the covenants contained in Article 4 below and the conditions
set forth in Section 3.03, and except as may be limited by applicable law. The
Initial Notes will be issued in an aggregate principal amount of $500,000,000.
All the Original Notes shall vote and consent together on all matters as one
class, and none of the Original Notes will have the right to vote or consent as
a class separate from one another on any matter. Subject to the covenants
contained in Article 4 below, the Company may issue Additional Notes hereunder.
Additional Notes (including any Exchange Notes issued in exchange therefor)
shall vote (or consent) as a class with the other Notes and otherwise be treated
as Notes for all purposes of this Indenture.

     The Notes shall be known and designated as the "10 7/8% Senior Subordinated
Notes Due 2009" of the Company. The final Stated Maturity of the Notes shall be
May 1, 2009. Interest on the Outstanding principal amount of Notes will accrue,
subject to Section 3.11, at the rate of 10 7/8% per annum and will be payable
semiannually in arrears on May 1 and November 1 in each year, commencing on
November 1, 1999, to Holders of record at the close of business on the
immediately preceding April 15 and October 15, respectively (each such April 15
and October 15, a "Regular Record Date"). Interest on the Original Notes will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid, from May 17, 1999, and interest
on any Additional Notes (and Exchange Notes issued in exchange therefor) will
accrue from the most recent date to which interest has been paid or duly
provided for or, if no interest has been paid on such Additional Notes, from the
date of issuance of such Additional Notes; provided that if any Note is
surrendered for exchange on or after a record date for an Interest Payment Date
that will occur on or after the date of such exchange, interest on the Note
received in exchange thereof will accrue from the date of such Interest Payment
Date.  The Company will pay interest on overdue principal and, to the extent
lawful, interest on overdue installments of interest and Liquidated Damages, if
any, at a rate of 1% per annum in excess of the interest rate referred to above.

                                       37


     The principal of, and premium, if any, and interest and Liquidated Damages,
if any, on the Notes shall be payable at the Corporate Trust Office or at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York (each, a "Place of Payment") in the manner
provided in Section 4.01(b); provided, however, that, under the circumstances
set forth in Section 4.01(b), payment of interest and Liquidated Damages on a
Note may be made by wire transfer of immediately available funds to the account
specified by the Holder of a Global Note or by check mailed to the address of
the Person entitled thereto as such address shall appear in the Register.

     Section 3.02.  Denominations.  The Notes shall be issuable only in
registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof.

     Section 3.03. Execution, Authentication and Delivery and Dating. The Notes
shall be executed on behalf of the Company by an Officer of such Company. The
signature of such Officer on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signature of an individual who was at
any time a proper Officer of the Company shall bind the Company, notwithstanding
that such individual has ceased to hold such office prior to the authentication
and delivery of such Notes or did not hold such office at the date of such
Notes.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes for original issue in the aggregate principal amount not to exceed
$500,000,000 and (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Company in the form of an Officer's
Certificate (an "Authentication Order"), and in the case of clause (ii), upon
receipt by the Trustee of an Opinion of Counsel confirming that the Holders of
the Outstanding Notes will be subject to federal income tax in the same amounts,
in the same manner and at the same times as would have been the case if such
Additional Notes were not issued. Such Officer's Certificates shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes, Additional Notes or
Exchange Notes, that the issuance of such Notes (in the case of Additional
Notes) does not contravene any provision of Article 4 of this Indenture, whether
the Notes are to be issued as one or more Global Notes or Physical Notes, the
name or names of the initial Holder or Holders, and such other information as
the Company may include or the Trustee may reasonably request.

     All Notes shall be dated the date of their authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Note a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

                                       38


     Section 3.04.  Temporary Notes.    Until definitive Notes are ready for
delivery, the Company may prepare and upon receipt of an Authentication Order
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company consider appropriate for temporary Notes. If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable
delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the
office or agency of the Company in a Place of Payment, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Company shall execute and upon receipt of an Authentication Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes of the same series and tenor.

     Section 3.05.  Registration, Registration of Transfer and Exchange.  The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Register") in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of Notes and
of transfers of Notes. The Trustee is hereby appointed "Registrar" for the
purpose of registering Notes and transfers of Notes as herein provided.

     Upon surrender for transfer of any Note at the office or agency of the
Company in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes, of any authorized denominations and of a
like aggregate principal amount.

     At the option of the Holder, Notes may be exchanged for other Notes, of any
authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive; provided that no exchange of Initial Notes or
Initial Additional Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the SEC and the
Trustee shall have received an Officer's Certificate confirming that the
Exchange Offer Registration Statement has been declared effective by the SEC and
an exchange offer thereunder has been consummated.  The Initial Notes or
Additional Notes to be exchanged for the Exchange Notes shall be canceled by the
Trustee.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

                                       39


     Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes under this
Section 3.05.

     Section 3.06.  Mutilated, Destroyed, Lost and Stolen Notes.  If (a) any
mutilated Note is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b)  there is delivered to the Company and the Trustee such security
or indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Company or the Trustee that such Note has been
acquired by a bona fide purchaser, the Company shall execute and upon receipt of
an Authentication Order the Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
Outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and ratably with
any and all other Notes duly issued hereunder.

     The provisions of this Section 3.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     Section 3.07.  Payment of Interest Rights Preserved.  Interest and
Liquidated Damages on any Note that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest and Liquidated Damages
specified in Section 3.01.

     Any interest and Liquidated Damages on any Note that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the

                                       40


relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest shall be paid by the Company, as provided in 3.07(a) or
3.07(b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Notes (or their respective Predecessor Notes) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as provided in this Section 3.07(a).  Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest,
the amount thereof and the Special Record Date and payment date therefor to be
mailed, first class postage prepaid, to each Holder at such Holder's address as
it appears in the Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered on such Special Record Date and shall no longer be payable
pursuant to the following 3.07(b).

     (b)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause (b), such payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest (including
any Liquidated Damages) accrued and unpaid, and to accrue, that were carried by
such other Note.

     Section 3.08.  Persons Deemed Owners.   Prior to due presentment of a Note
for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of (and premium, if any, on) and (subject to Section 3.07) interest
and Liquidated Damages, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Company, the
Subsidiary Guarantors, the Trustee or any agent of the Company,  the Subsidiary
Guarantors or the Trustee shall be affected by notice to the contrary.

     Section 3.09. Cancellation. All Notes surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the

                                       41


Trustee, be delivered to the Trustee and, if not already canceled, shall be
promptly canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder that the
Company may have acquired in any manner whatsoever, and all Notes so delivered
shall be promptly canceled by the Trustee. No Notes shall be authenticated in
lieu of or in exchange for any Notes canceled as provided in this Section 3.09,
except as expressly permitted by this Indenture. All canceled Notes held by the
Trustee shall be disposed of in accordance with the Trustee's customary
procedures.

     Section 3.10.  Computation of Interest.  Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

     Section 3.11.  Payment of Liquidated Damages.  (a)  Under certain
circumstances the Company will be obligated to pay certain Liquidated Damages to
the Holders of certain Initial Notes, as more particularly set forth in such
Initial Notes.

     (b)  Under certain circumstances the Company may be obligated to pay
certain Liquidated Damages to the Holders of certain Initial Additional Notes,
as may be more particularly set forth in such Initial Additional Notes.

     Section 3.12.  CUSIP Numbers.  The Company in issuing the Notes may use
"CUSIP" or "CINS" numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such "CUSIP" or "CINS" numbers in
addition to serial numbers in notices of redemption, repurchase or other notices
to Holders as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such "CUSIP" or "CINS"
numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Notes, and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the "CUSIP" or

     Section 3.13.  Book-entry Provisions for Global Notes.

     (a)  Each Global Note initially shall (i) be registered in the name of the
Depositary for such Global Notes or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) to the
extent relevant thereto, bear legends as set forth in Section 2.03.  None of the
Company or the Subsidiary Guarantors, nor any of their agents shall have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of beneficial ownership interests of, a Global Note, or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note, and the
Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Subsidiary
Guarantors, the Trustee or any agent of the

                                       42


Company, the Subsidiary Guarantors or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a beneficial owner
of any Note. The registered Holder of a Global Note may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

     (b)  Interests of beneficial owners in a Global Note may be transferred in
accordance with the applicable rules and procedures of the Depositary and the
provisions of Section 3.14.  Transfers of a Global Note shall be limited to
transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees, except (i) upon request of an Agent
Member (for itself or on behalf of a beneficial holder) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary
procedures of the Depositary and (ii) Physical Notes shall be transferred to
beneficial owners in exchange for their beneficial interests in the Global Notes
in the event that (A) the Depositary (1) notifies the Company that it is
unwilling or unable to continue as Depositary for the applicable Global Note and
a successor depositary is not appointed by the Company within 90 days or (2)
the Depositary ceases to be a "Clearing Agency" registered under the Exchange
Act , (B) the Company, at its option, notifies the Trustee in writing that it
elects to cause the issuance of Physical Notes under this Indenture or (C) there
shall have occurred and be continuing a Default or Event of Default.  In
connection with any transfer or exchange of a portion of the beneficial interest
in any Global Note to beneficial owners for Physical Notes pursuant to paragraph
(b) of this Section 3.13, the Registrar shall record on its books and records
(and make a notation on the Global Note of) the date and a decrease in the
principal amount of such Global Note in an amount equal to the beneficial
interest in the Global Note being transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Notes of
like tenor and principal amount of authorized denominations. In connection with
a transfer of an entire Global Note to beneficial owners pursuant to clause (ii)
of this paragraph (b), the applicable Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
the Trustee shall authenticate and deliver, to each beneficial owner identified
by the Depositary in exchange for its beneficial interest in the applicable
Global Note, an equal aggregate principal amount at maturity of Physical Notes
of authorized denominations.

     (c)  Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

     (d)  The Company, the Subsidiary Guarantors, any other obligor upon the
Notes or the Trustee, in the discretion of any of them, may treat as the Act of
a Holder any instrument or writing of any Person that is identified by the
Depositary as the owner of a beneficial interest in the Global Note, provided
that the fact and date of the execution of such instrument or writing is proved
in accordance with Section 1.08(b).

                                       43


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

     Section 3.14. Transfer Provisions.  Unless and until (i) an Initial Note or
any Initial Additional Note is sold pursuant to an effective registration
statement, whether pursuant to the Registration Rights Agreement or otherwise,
or (ii) an Initial Note or any Initial Additional Note is exchanged for an
Exchange Note in the Exchange Offer pursuant to an effective Registration
Statement pursuant to the Registration Rights Agreement, the following

        has otherwise certified to the Company and the Registrar in writing,
        that the sale has been made in compliance with the provisions of Rule
        144A to a transferee who has signed the certification provided for on
        the form of such Note stating, or has otherwise certified to the Company
        and the Registrar in writing, that it is purchasing such Note for its
        own account or an account with respect to which it exercises sole
        investment discretion and that it and any such account is a QIB within
        the meaning of Rule 144A, and is aware that the sale to it is being made
        in reliance on Rule 144A and acknowledges that it has received such
        information regarding the Company as it has requested pursuant to Rule
        144A or has determined not to request such information and that it is
        aware that the transferor is relying upon its foregoing representations
        in order to claim the exemption from registration provided by Rule 144A;
        and

                (ii) if the proposed transferee is or is acting through an Agent
        Member, and the Note to be transferred consists of (A) a Physical Note
        that after transfer is to be evidenced by an interest in a Global Note
        or (B) a beneficial interest in a Global Note that after the transfer is
        to be evidenced by a Physical Note, upon receipt by the Registrar of
        written instructions given in accordance with the Depositary's and the
        Registrar's procedures,

(I) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and an increase in the
principal amount of the transferee Global Note or (y) deliver Physical Notes, in
each case in an amount equal to the principal amount of the Physical Note or
such beneficial interest in such transferor Global Note to be transferred, and
(II) the Trustee shall (x) cancel the Physical Note so transferred or (y)
reflect on its books and records (and make a notation on the relevant Global
Note of) the date and a decrease in the principal amount of such transferor
Global Note, as the case may be.

                                       44


     (c)  Transfers pursuant to Rule 144 and transfer to Lyondell.  With respect
to the registration of any proposed transfer of a Note that is a Restricted

Act provided by Rule 144 thereunder or (ii) to the Company, the Register shall
register such transfer if it complies with all other requirements of this
Indenture (including Section 3.05 and Section 3.13) and,

                (A) if such transfer is being made by a proposed transferor who
        has checked the box provided for on the form of such Note stating, or
        has otherwise certified to the Company and the Registrar in writing,
        that the sale has been made in compliance with the provisions of Rule
        144 or that such sale has been made to the Company; and

                (B) if the proposed transferee is not the Company and is or is

        relevant Global Note of) the date and an increase in the principal
        amount of the transferee Global Note or (y) deliver Physical Notes, in
        each case in an amount equal to the principal amount of the Physical
        Note or such beneficial interest in such transferor Global Note to be
        transferred, and (II) the Trustee shall (x) cancel the Physical Note so
        transferred or (y) reflect on its books and records (and make a notation
        on the relevant Global Note of) the date and a decrease in the principal
        amount of such transferor Global Note, as the case may be; and

                (C) if the proposed transferee is the Company, (I) the Registrar

        certifications or other information to confirm that any proposed
        transfer is being made pursuant to Rule 144 under the Securities Act.

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

requested transfer is after the relevant Resale Restriction Termination Date
with respect to such Notes, (ii) upon written request of the Company after there
is delivered to the Registrar an opinion of counsel (which opinion and counsel
are satisfactory to the Company and the Trustee) to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act, or (iii) such
Notes are sold or exchanged pursuant to an effective registration statement
under the Securities Act.

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

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.13 or this Section 3.14 (including

shall have the right to require the Registrar to deliver to the Company, at the
Company' expense, copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

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

     (i)  Certain Additional Terms Applicable to Physical Notes. Any transferee
entitled to receive a Physical Note may request that the principal amount
thereof be

                                       46


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.

     Section 4.01.  Payment of Principal, Premium and Interest.  (a) The Company
will duly and punctually pay the principal of (and premium, if any) and interest

interest and Liquidated Damages shall be considered paid on the date it is due
if the Trustee or Paying Agent or Paying Agents hold on that date money
designated for and sufficient to pay the installment.

     (b)  Payments (including principal, premium, if any, interest and
Liquidated Damages, if any) in respect of the Notes represented by the Global
Notes, the Holder of which has given wire transfer instructions on or prior to
the relevant record date, shall be made by wire transfer of immediately

respect to Physical Notes, the Company will make all payments of principal,
premium, if any, interest and Liquidated Damages, if any, at the office or

any change in the location, of such office or agency. If at any time the Company
shall fail to maintain such office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee. The
Company hereby designates the Corporate Trust Office as an initial Place of
Payment and as such office of the Company in the Borough of Manhattan, The City
of New York, and appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands so long as such Corporate Trust
Office remains a Place of Payment.

     Section 4.03. Money for Payments to Be Held in Trust. If the Company shall
at any time act as its own Paying Agent, it will, on or before each due date of
the principal of (and premium, if any) or interest and Liquidated Damages, if
any, on, any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest and Liquidated Damages, if any, so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, it will, prior to
each due date of the principal of (and premium, if any) or interest and
Liquidated Damages, if any,

                                       47


on, any Notes, deposit with a Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest and Liquidated Damages, if any, so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium or interest and Liquidated Damages, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

     If the Company is not acting as its own Paying Agent, the Company will
cause any Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 4.03, that such Paying Agent will:

     (a)  hold all sums held by it for the payment of principal of (and premium,
if any) or interest and Liquidated Damages, if any, on Notes in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

     (b)  give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any such payment of principal (and
premium, if any) or interest and Liquidated Damages, if any;

                                       48


     (c)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d)  acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture and TIA relating to the duties, rights and
liabilities of such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest and Liquidated Damages, if any, on any Note and remaining unclaimed
for two years after such principal (and premium, if any) or interest and
Liquidated Damages, if any, has become due and payable shall be paid in the
appropriate proportion to the Company upon a Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease.

     Section 4.04.  SEC Reports. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes issued hereunder are outstanding,

under the Securities Act.

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

and (c) hereof to the Holders at their addresses appearing in the Register
maintained by the Registrar.

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

     Section 4.05.  Certificates to Trustee. (a) The Company will deliver to the
Trustee within 120 days after the end of each fiscal year of the Company a
certificate from the principal executive, financial or accounting officer of the
Company stating that such officer has conducted or supervised a review of the
activities of the Company and its Restricted Subsidiaries and the Company's and
its Restricted Subsidiaries' performance under this Indenture and that, based
upon such review, to the best of such officer's knowledge, the Company has
fulfilled all obligations thereunder or, if there has been a default in the
fulfillment of any such obligation (determined without regard to any period of
grace or requirement of notice provided in this Indenture), specifying each such
default and the nature and status thereof.

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

     (c)  The Company will deliver to the Trustee within 120 days after the end
of each fiscal year of the Company a written statement by the Company's
independent public accountants stating (i) that their audit examination has

accounting matters, and (ii whether, in connection with their audit examination,

attention, specifying the nature and period of the existence thereof.

     Section 4.06. Limitation on Indebtedness. (a) On or after the Issue Date:

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

                (ii) the Company will not, and will not permit any of its
        Restricted Subsidiaries to, issue any Disqualified Stock (including
        Acquired Disqualified Stock);

                (iii) and the Company will not permit any of its Restricted
        Subsidiaries that are not Subsidiary Guarantors to issue any shares of
        Preferred Stock (including Acquired Preferred Stock);

                                       50


provided, however, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired
Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
Letters of credit and bankers' acceptances shall be deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

     (b)  The foregoing provisions will not apply to:

                (i) the incurrence by the Company of Indebtedness pursuant to
        the Existing Credit Facility (and by its Subsidiaries of Guarantees
        thereof) in an aggregate principal amount at any time outstanding not to
        exceed an amount equal to $3.87 billion less the aggregate amount of all
        mandatory repayments (other than mandatory prepayments triggered solely
        by the issuance of Indebtedness or Preferred Stock of a Finance
        Subsidiary to refinance the Existing Credit Facility) applied to (x)
        repay loans (other than revolving credit loans) outstanding thereunder
        or (y) permanently reduce the revolving credit commitments thereunder;

                (ii) the incurrence by the Company and the Subsidiary Guarantors
        of Indebtedness represented by the Senior Secured Notes issued on the
        Issue Date, the Original Notes (but not any Additional Notes) and the
        Subsidiary Guarantees thereof;

                (iii) the incurrence by the Company and its Restricted
        Subsidiaries of Existing Indebtedness (other than Indebtedness of the
        type described in clauses (i), (ii) or (v) through (xii) of this
        covenant);

                (iv) the incurrence by the Company or any of its Restricted
        Subsidiaries of any Permitted Refinancing in exchange for, or the net
        proceeds of which are used to extend, refinance, renew, replace, defease
        or refund, Indebtedness that was permitted to be incurred under the
        Fixed Charge Coverage Ratio test set forth above or clauses (ii) or
        (iii) above or (xiii) or (xiv) below or this clause (iv);

                (v) the incurrence by the Company or any of its Restricted
        Subsidiaries of intercompany Indebtedness between or among the Company
        and any of its Restricted Subsidiaries; provided, however, that (i) if
        the Company or any Subsidiary Guarantor is the obligor on such
        Indebtedness, such Indebtedness is expressly subordinated to the prior

        (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

                of the Company's most recently ended fiscal quarter for which
                financial statements have been filed with the SEC pursuant to
                Section 4.04 at the time of such Restricted Payment (or, if such
                Consolidated Net Income for such period is a deficit, less 100%
                of such deficit), plus

                (ii) 100% of the aggregate net cash proceeds received by the
                Company or any of its Restricted Subsidiaries from the issue or

                Company) after the Issue Date of Qualified Equity Interests of
                the Company or of debt securities of the Company or any of its
                Restricted Subsidiaries that have been converted into or
                exchanged for such Qualified Equity Interests of the Company,
                plus

                (iii) to the extent that any Restricted Investment (other than a
                Restricted Investment permitted to be made pursuant to Section

                the Issue Date is sold for cash or otherwise liquidated, repaid
                or otherwise reduced, including by way of dividend (to the
                extent not included in calculating Consolidated Net Income), for
                cash, the lesser of (A) the cash return with respect to such
                Restricted Investment (less the cost of disposition, if any) and
                (B) the initial amount of such Restricted Investment plus

                (iv) an amount equal to the sum of (A) the net reduction in

                in each case to the Company or any Restricted Subsidiary from
                Unrestricted Subsidiaries and (B) the portion (proportionate to
                the Company's equity interest in such Subsidiary) of the fair
                market value of the net assets of an Unrestricted Subsidiary at
                the time such Unrestricted Subsidiary is designated a Restricted
                Subsidiary; provided, however, that the foregoing sum shall not
                exceed, in the case of any Unrestricted Subsidiary, the amount
                of Restricted Investments (other

                                       55

                made after the Issue Date by the Company or any Restricted
                Subsidiary in such Unrestricted Subsidiary.

     (b)  If, other than with respect to payments made under 4.07(b)(i) and
4.07(b)(xiv) below, no Default or Event of Default shall have occurred and be
continuing after giving effect to such Restricted Payment, the foregoing
provisions will not prohibit the following Restricted Payments:

        not exceed $100.0 million and (B) the pledge of the Capital Stock of
        such Joint Venture or Unrestricted Subsidiary or of a Joint Venture
        Subsidiary that has no assets and conducts no operations other than the

        to secure Non-Recourse Debt of such Joint Venture or Unrestricted
        Subsidiary;

                (xii) (A) (x) the transfer of the TDI Assets to a newly formed
        Joint Venture or Unrestricted Subsidiary or (y) the designation of any
        Restricted Subsidiary that has no assets or liabilities other than all

        case, in connection with the incurrence of Indebtedness by such Joint
        Venture or Unrestricted Subsidiary or

                                       58

        Plant and (B) the pledge of the Capital Stock of such Joint Venture or
        Unrestricted Subsidiary or of a Joint Venture Subsidiary that has no
        assets and conducts no operations other than the holding directly or

        Sale pursuant to a provision no more favorable to the holders thereof
        than the provisions of Section 4.09; provided that, in each case, prior

        validly tendered for payment in connection with such Change of Control
        Offer or Asset Sale Offer;

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

        Restricted Payments made pursuant to this Section 4.07(b)(xv) on or
        after the date of the Indenture, does not exceed $25 million (after
        giving effect to any subsequent reduction in the amount of any
        Investments made pursuant to this Section 4.07(b)(xv) as a result of the
        repayment or other disposition thereof for cash as set forth in clause
        (iii) of the first paragraph above, the amount of such reduction not to
        exceed the amount of such Investments previously made pursuant to this
        Section 4.07(b)(xv)); and

                (xvi) dividends or distributions by any Joint Venture (other
        than a Specified Joint Venture) to all holders of a class of Capital
        Stock of such Joint Venture permitted by Section 4.07(b)(ii)(x) above;
        provided that after giving effect to such dividends or distributions and
        any related transactions, the Joint Venture making such dividends or
        distributions to such holders is contractually entitled to receive, and
        receives within 180 days before or after the date of such dividends or
        distributions, directly or indirectly, an equivalent or larger cash
        payment from each such holder (other than from a holder that is the
        Company or any Restricted Subsidiary) or from an Affiliate of such
        holder, which cash payment has not been previously applied pursuant to
        this Section 4.07(b)(xvi) to offset any other dividend or distribution
        by such Joint Venture to such holder and (y) such dividends or
        distributions do not exceed such holders' pro rata share of the Joint
        Venture's cash flows from operating activities, minus any non-cash
        charge to the extent that it represents an accrual of or reserve for
        cash

                                       59


        expenditures in any future period or amortization of a prepaid cash
        expense in any future period.

     (c)  The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments Section
4.07(a) (except to the extent such Investments were repaid in cash, and, in the
case of a Joint Venture (and any Subsidiary of a Joint Venture) designated as an
Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company,
except to the extent that (1) such Investments were made after the Issue Date or
(2) in the case of a Specified Joint Venture, such Investments were made prior
to the Issue Date). All such outstanding Investments (except as provided in the
parenthetical included in the preceding sentence) will be deemed to constitute
Investments in an amount equal to the fair market value of such Investments at
the time of such designation (as conclusively determined by the Board of
Directors). Such designation will only be permitted if any such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. In the case of any
designation by the Company of a Person as an Unrestricted Subsidiary on the
first day that such Person is a Subsidiary of the Company in accordance with the
provisions of the Indenture, such designation shall be deemed to have occurred
for all purposes of the Indenture simultaneously with, and automatically upon,
such Person becoming a Subsidiary.

     (d)  Not later than the date of making any Restricted Payment, other than
those permitted by Sections 4.07(b)(ii)(x), 4.07(b)(vi), 4.07(b)(x) and
4.07(b)(xiv) above, and not later than the 120th day after making any Restricted
Payment permitted by Section 4.07(b)(vi) above, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

     Section 4.08.  Limitation on Dividend and other Payment Restrictions
affecting Restricted Subsidiaries and Joint Ventures.  (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
restriction on the ability of any Restricted Subsidiary to:

                (i) (A) pay dividends or make any other distributions to the
        Company or any of its Restricted Subsidiaries (1) on its Capital Stock
        or (2) with respect to any other interest or participation in, or
        measured by, its profits or (B) pay any Indebtedness owed to the Company
        or any of its Restricted Subsidiaries;

                (ii) make loans or advances to the Company or any of its
        Restricted Subsidiaries; or

                (iii) transfer any of its properties or assets to the Company or
        any of its Restricted Subsidiaries;

                                       60


     except for such restrictions existing under or by reason of:

     (a) existing agreements as in effect on the Issue Date;

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

     (c) the Indenture and the Senior Secured Notes Indentures;

     (d) applicable law;

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

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

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

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

     (i) a Permitted Refinancing, provided that the restrictions contained in
the agreements governing such Permitted Refinancing are not materially more
restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced (as conclusively evidenced by a Board
Resolution);

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

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

     (l) in the case of any Restricted Subsidiary that is a Joint Venture,
customary restrictions on such Restricted Subsidiary contained in its joint
venture agreement, which

                                       61


restrictions are consistent with the past practice of the Company and its
Restricted Subsidiaries (as conclusively evidenced by a Board Resolution);

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

     (n) the Existing Credit Facility and related documentation as the same is
in effect on the Issue Date and as amended, modified, extended, renewed,
refunded, refinanced, restated or replaced from time to time; provided that the
Existing Credit Facility and related documentation as so amended, modified,
extended, reviewed, refunded, refinanced, restated or replaced is not materially
more restrictive, taken as a whole, as to the matters enumerated above than the
Existing Credit Facility and related documentation as in effect on the Issue
Date (as conclusively evidenced by a Board Resolution).

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

     (b)  The Company will use best efforts (consistent with its contractual
obligations and fiduciary duties to any Joint Venture, in each case, as in
effect on the Issue Date) not to permit any of its Joint Ventures that are not
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any restriction on the ability of such Joint
Venture to:

                (i) (A) pay dividends or make any other distributions to the
        Company or any of its Restricted Subsidiaries (1) on its Capital Stock
        or (2) with respect to any other interest or participation in, or
        measured by, its profits or (B) pay any Indebtedness owed to the Company
        or any of its Restricted Subsidiaries;

                (ii) make loans or advances to the Company or any of its
        Restricted Subsidiaries; or

                (iii) transfer any of its properties or assets to the Company or
        any of its Restricted Subsidiaries;

     except for such restrictions existing under or by reason of:

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

                                       62


     (b) in the case of any Joint Venture existing on the Issue Date, its
existing agreements as in effect on the date of the Indenture and as amended,
modified, extended, restated or replaced from time to time; provided that no
such amendment, modification, extension, restatement or replacement results in
agreements that are materially more restrictive, taken as a whole, as to the
matters enumerated above than the existing agreements as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution);

     (c) in the case of LCR, any instrument governing its Indebtedness; and

     (d) the restrictions described in clauses (d), (e), (f), (g), (h), (j), (k)
and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k) to a
Restricted Subsidiary were references to a Joint Venture).

     Section 4.09.  Limitation on Sales of Assets.   (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, consummate an Asset
Sale unless:

                (i) the Company and/or the Restricted Subsidiary, as the case
        may be, receives consideration at the time of such Asset Sale at least
        equal to the fair market value (as conclusively evidenced by a Board
        Resolution set forth in an Officers' Certificate delivered to the
        Trustees) of the assets or Equity Interests issued or sold or otherwise
        disposed of; and

                (ii) at least 80% of the consideration therefor received by the
        Company and/or such Restricted Subsidiary is in the form of

                        (A) cash or Cash Equivalents or

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

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

     (b)  Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

                (i) to permanently repay Senior Indebtedness (and to
        correspondingly reduce commitments with respect thereto in the case of
        revolving borrowings) of

                                       63


        the Company or a Subsidiary Guarantor or Indebtedness (and to
        correspondingly reduce commitments with respect thereto in the case of
        revolving borrowings) of any Restricted Subsidiary that is not a
        Subsidiary Guarantor; or

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

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce the revolving Indebtedness under the Existing Credit Facility
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the first sentence of this Section 4.09(b) will be
deemed to constitute "Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $25 million, the
Company will be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and, if the
Company is required to do so under the terms of any other Indebtedness ranking
pari passu with such Notes, such other Indebtedness, on a pro rata basis with
the Notes, that may be purchased out of the Excess Proceeds, at an offer price
in cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
purchase, in accordance with the procedures set forth herein

     Prior to complying with the provisions of this Section 4.09, the Company
will either repay all outstanding Senior Indebtedness or obtain the requisite
consents, if any, under all agreements governing outstanding Senior
Indebtedness, to the extent necessary, to permit the repurchase of Notes
required by this covenant.

     To the extent that the aggregate amount of Notes (and any other pari passu
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offer is less than the Excess Proceeds, the Company may, subject to the
other terms of the Indenture, use any remaining Excess Proceeds for general
corporate purposes.

     If the aggregate principal amount of Notes surrendered by Holders thereof
in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased on a pro rata basis.

     Upon completion of the offer to purchase made under the Indenture, the
amount of Excess Proceeds shall be reset at zero.

                                       64


        (d) The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with any Asset
Sale Offer.

     Section 4.10.  Limitation on Affiliate Transactions.  (a)  The Company will
not, and will not permit any of its Restricted Subsidiaries to, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on an arms-length basis and (ii) the Company delivers
to the Trustee (a) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $10 million, a Board Resolution set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess
of $25 million, an opinion as to the fairness to the Company or such Restricted
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an investment banking firm of national standing; provided that:

     (i) transactions or payments pursuant to any employment arrangements or
employee, officer or director benefit plans or arrangements entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business;

     (ii) transactions between or among the Company and/or its Restricted
Subsidiaries;

     (iii) any Restricted Payment permitted by Section 4.07 of the type
described in clause (i) or (ii) of the first paragraph thereof;

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

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

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

     (vii) transactions pursuant to any contract or agreement in effect on the
date of the Indenture as the same may be amended, modified or replaced from time
to time so long as any such contract or agreement as so amended, modified or
replaced is, taken as a whole, no less favorable to the Company and its
Restricted Subsidiaries than the contract or agreement as in effect on the date
of the Indenture (as conclusively evidenced by a Board

                                       65


Resolution); in each case, shall not be deemed to be Affiliate Transactions and
therefore not subject to the requirements of clauses (i) and (ii) of the initial
sentence above.

     Section 4.11.  Limitation on Liens.  The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien (except Permitted Liens) to secure
Indebtedness or other obligations that are pari passu with or subordinated by
their terms in right of payment to the Notes or the Subsidiary Guarantees on any
asset now owned or hereafter acquired, or any income or profits therefrom,
unless all payments due under the  Indenture and the  Notes or the Subsidiary
Guarantees are secured on an equal and ratable basis with the obligations so
secured (or, if such obligations are subordinated by their terms to the Notes or
the  Subsidiary Guarantees, prior to the obligations so secured) until such time
as such obligations are no longer so secured.

     Section 4.12.  Limitation on Senior Subordinated Indebtedness.  The Company
and the Subsidiary Guarantors will not incur any Indebtedness that pursuant to
its terms is subordinate or junior in right of payment to any Senior
Indebtedness and senior in any respect in right of payment to the Notes or the
Subsidiary Guarantees; provided that the foregoing limitation shall not apply to
distinctions between categories of Senior Indebtedness of the Company or a
Subsidiary Guarantor that exist by reason of any Liens or Guarantees arising or
created in respect of some but not all such Senior Indebtedness.

     Section 4.13. Repurchase of Notes upon a Change in Control.  (a)   Upon the
occurrence of a Change of Control, each Holder will have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to the offer described below
(the "Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control (the "Change of Control Payment Date"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's
request the Trustee will mail, a notice to each Holder offering to repurchase
the Notes held by such Holder pursuant to the procedures specified in such
notice.

     (b)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
applicable Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered, and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officer's
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company.

                                       66


     The Paying Agent will promptly mail to each Holder of Notes so tendered the
Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such Note will be in a principal amount
of $1,000 or an integral multiple thereof.

     (d)  Prior to complying with the provisions of this covenant, but in any
event within 90 days following a Change of Control, the Company will either
repay all outstanding Senior Indebtedness or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Indebtedness, to the
extent necessary, to permit the repurchase of Notes required by this Section
4.13.

     (e)  The Company will not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer at
the same or a higher purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     Section 4.14.  Limitation on Sale and Leaseback Transactions.  The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any Sale and Leaseback Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Leaseback Transaction if: (a) the Company
or such Restricted Subsidiary, as the case may be, could have (i) incurred
Indebtedness in an amount equal to the Attributable Debt relating to such Sale
and Leaseback Transaction pursuant to the Fixed Charge Coverage Ratio test set
forth in Section 4.06(a) (whether or not such covenant has ceased to be
otherwise in effect pursuant to Section 4.17) and (ii) incurred a Lien to secure
such Indebtedness pursuant to Section 4.11 without securing the Notes; and (b)
the gross cash proceeds of such Sale and Leaseback Transaction are at least
equal to the fair market value (as conclusively determined by the Board of

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

     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

Accounts Receivable Subsidiary; provided that the aggregate consideration
received in each such sale is at least equal to the aggregate fair market value
of the receivables sold.

     Section 4.17.  Limited Applicability of Covenants when Notes are rated
Investment-Grade. Notwithstanding the foregoing, the Company's and its
Restricted Subsidiaries' obligations to comply with the provisions of Sections
4.06, 4.07, 4.08, 4.09, 4.10, 4.15, 4.16 and 4.21 will terminate and cease to

     Section 4.18.  Existence.  Subject to Articles 4 and 5 of this Indenture,
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with the respective organizational
documents of the Company and each such Subsidiary and the rights (whether
pursuant to charter, partnership certificate, agreement, statute or otherwise),
material licenses and franchises of the Company and each such Subsidiary;
provided that the Company shall not be required by this Section 4.18 to preserve
any such right, license or franchise, or the existence of any Restricted
Subsidiary, if the Company shall determine that the maintenance or preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries taken as a whole.

     Section 4.19.  Payment of Taxes and Other Claims.  The Company will pay or
discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (a) all material taxes, assessments and governmental charges levied
or imposed upon (i) the Company or any such Subsidiary, (ii) the income or
profits of any such Subsidiary which is a corporation or (iii) the property of
the Company or any such Subsidiary and (b) all material lawful claims for labor
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established in accordance with GAAP.

     Section 4.20.  Maintenance of Properties and Insurance.  The Company will
cause all material assets necessary in the conduct of its business or the
business of any of its Restricted Subsidiaries, to be maintained and kept in
good condition, repair and working order (ordinary wear and tear excepted) and
will cause to be made all necessary repairs, renewals, and replacements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided that nothing in this Section 4.20 shall prevent the Company or any such
Subsidiary from discontinuing the use, operation or maintenance of any of such
assets or disposing or abandoning of any of them, if such discontinuance,
disposal or abandonment is, in the judgment of the Company, desirable in the
conduct of the business of the Company or such Subsidiary.

     The Company will maintain, and will cause each of its Restricted
Subsidiaries to maintain (either in the Company's name or in such Subsidiary's
own name) insurance on all their respective properties consistent with the
insurance maintained on the Issue Date or otherwise in at least such amounts
(with no materially greater risk retention) and against at least such risks as
are usually maintained, retained or insured against in the same general area by
companies of established repute owning similar properties in such area and
engaged in the same or a similar business, in either case, to the extent
available to the Company and its Restricted Subsidiaries on commercially
reasonable terms.

     Section 4.21.  Limitation on Issuance of Guarantees by Restricted
Subsidiaries. (a) The Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee or secure the
payment of any other

                                       68


Indebtedness of the Company or any of its Restricted Subsidiaries (except
Indebtedness of such Restricted Subsidiary or a Restricted Subsidiary of such
Restricted Subsidiary) unless (i) such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture in the form of Exhibit B hereto
providing for the Guarantee of the payment of the Notes by such Restricted
Subsidiary and shall deliver an Opinion of Counsel to the Trustee pursuant to
paragraph (c) below; provided that this paragraph shall not be applicable to (x)
any Guarantee of any Restricted Subsidiary that existed at the time such Person
became a Restricted Subsidiary and was not incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary, (y) Guarantees
of Indebtedness of a Restricted Subsidiary that is a Foreign Subsidiary by a
Restricted Subsidiary that is a Foreign Subsidiary or (z) the granting of Liens
by a Joint Venture Subsidiary to secure Indebtedness under the Existing Credit
Facility and the Senior Secured Notes. If the Notes are (A) subordinated by
their terms to the Guaranteed Indebtedness, then the Subsidiary Guarantee shall
be subordinated to the guarantee of such Guaranteed Indebtedness, (B) pari passu
with the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be pari
passu with, or senior to, the guarantee of such Guaranteed Indebtedness or (C)
senior to the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be
senior to the guarantee of such Guaranteed Indebtedness at least to the extent
that the Notes are senior to such Guaranteed Indebtedness.

     (b)  Notwithstanding the foregoing, each Subsidiary Guarantee by a
Restricted Subsidiary shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all the Company's and each Restricted Subsidiary's
Capital Stock in such Restricted Subsidiary (which sale, exchange or transfer is
not prohibited by the Indenture) as provided in Section 5.03(b), (ii) the
release or discharge of the Guarantee which resulted in the creation of such
Subsidiary Guarantee (or, in the case of the Subsidiary Guarantees of Lyondell
Chemical Worldwide, Inc. and Lyondell Chemical Nederland, Ltd. issued on the
Issue Date, the release or discharge of its Guarantee of Indebtedness under the
Existing Credit Facility), except a discharge or release by or as a result of
payment under such Guarantee, and (iii) the designation of such Restricted
Subsidiary as an Unrestricted Subsidiary in accordance with the terms of the
Indenture.

        (c) The Opinion of Counsel described above shall be to the effect that
such supplemental indenture has been duly authorized, executed and delivered by
such Subsidiary and constitutes a valid and binding obligation of such
Subsidiary, enforceable against such Subsidiary in accordance with its terms
(subject to customary exceptions).

     Section 4.22.  Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes that consent, waive or agree to amend such term or provision in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

        applicable four-quarter period, be permitted to incur at least $1.00 of
        additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
        set forth in Section 4.06(a). The foregoing shall not prohibit the
        merger or consolidation of a Wholly Owned Restricted Subsidiary with the
        Company; provided that, in connection with any such merger or
        consolidation, no consideration (other than common stock in the

consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, conveyance or other disposition is made shall succeed to,
and be substituted for (so that from and after the date of such consolidation,
merger, sale, assignment, transfer, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation), and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein, and the predecessor Company shall be
released from all its obligations hereunder and under the Notes.

     (b)  The sale, assignment, transfer, lease, conveyance or other disposition
by the Company of all or substantially all its property or assets taken as a
whole to one or more of the Company's Subsidiaries shall not relieve the Company
from its obligations under the Indenture and the Notes.

     Section 5.03. Consolidation, Merger or Sale of Assets by a Subsidiary
Guarantor.  (a) No Subsidiary Guarantor may consolidate with or merge with or
into (whether or not such Subsidiary Guarantor is the surviving Person), another
corporation, Person or entity whether or not affiliated with such Subsidiary
Guarantor unless:

                (i) subject to the provisions of Section 5.03(b) below, the

        indenture in form and substance reasonably satisfactory to the Trustee,
        under the Notes;

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

                (iii) the Company would, at the time of such transaction and
        after giving pro forma effect thereto as if such transaction had
        occurred at the beginning of the applicable four-quarter period, (A)
        have a Consolidated Net Worth immediately after the transaction equal to
        or greater than the Consolidated Net Worth of the Company immediately
        preceding the transaction and (B) except with respect to a consolidation
        or merger with a Person that has no outstanding Indebtedness, be
        permitted to incur at least $1.00 of additional Indebtedness pursuant to
        the Fixed Charge Coverage Ratio test set forth in 4.06(a).

not apply in the case of a consolidation with or merger with or into the Company
and the requirements of clause (iii) of Section 5.03(a) will not apply in the

consolidation or otherwise, of all the Capital Stock of any Subsidiary Guarantor
to any Person that is not an Affiliate of the Company permitted by the
applicable provisions of the Indenture, such Subsidiary Guarantor will be
released and relieved of any obligations under its Subsidiary Guarantee;

transfer, lease, exchange or other disposition referred to in Section 5.01 or
5.03 complies with the applicable provisions of this Indenture.



                                   ARTICLE 6
                                   REMEDIES

of 25% or more in aggregate principal amount of the Notes;

     (e)  any default occurs under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Significant
Subsidiaries (or any Indebtedness for money borrowed Guaranteed by the Company
or any of its Significant Subsidiaries if the Company or a Significant
Subsidiary does not perform its payment obligations under such Guarantee within
any grace period provided for in the documentation governing such Guarantee)
and, whether such Indebtedness or Guarantee exists on the date of the indenture
or is thereafter created, which default (a) constitutes a Payment Default or (b)
results in the acceleration of such Indebtedness prior to its Stated Maturity,
and in each case, the principal amount of any such Indebtedness, together with

                                       72


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;

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

     (h)  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,

Significant Subsidiary or (ii effects any general assignment for the benefit of
creditors; or

     (i)  except as permitted by the Indenture, any Subsidiary Guarantee issued
hereunder shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall deny or disaffirm its obligations under the Subsidiary
Guarantees issued thereunder.

     Section 6.02.  Acceleration.  (a) If an Event of Default (other than an
Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Subsidiary Guarantor) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then Outstanding, by written notice to the Company
(and to the Trustee if such notice is given by the Holders (the "Acceleration
Notice")), may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued but unpaid interest and
Liquidated Damages, if any, on all the Notes to be due and payable.  Upon a
declaration of acceleration, such principal, premium, if any, and accrued
interest and Liquidated Damages, if any, shall be immediately due and payable.
If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs
with respect to the Company or any Subsidiary Guarantor, the principal of,
premium, if any, accrued interest and Liquidated Damages, if any, on the Notes
then Outstanding shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

                                       73


     (b)  If payment of the Notes is accelerated because of an Event of Default,
the Company or the Trustee shall promptly notify the holders of Designated
Senior Indebtedness or the Representative of such holders of the acceleration.

     Section 6.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest and Liquidated Damages on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  All remedies are cumulative
to the extent permitted by law.

     Section 6.04.  Waiver of Past Defaults.  The Holders of at least a majority
in principal amount of the outstanding Notes, by written notice to the Company
and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences under the Notes, if (i) all
existing Events of Default, other than the nonpayment of the principal of and
premium, if any, and interest and Liquidated Damages, if any, on such Notes that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     Section 6.05.  Control by Majority.  The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from the
Holders.

     Section 6.06. Limitation on Suits.  A Holder may not pursue any remedy with
respect to this Indenture or the Notes unless:

     (a)  the Holder gives the Trustee written notice of a continuing Event of
Default;

     (b)  the Holders of at least 25% in aggregate principal amount of
Outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c)  such Holder or Holders offer the Trustee security or indemnity
satisfactory to it against any loss, liability or expense;

                                       74


     (d)  the Trustee does not comply with the request within 60 days after
receipt thereof and the offer of security or indemnity; and

     (e)  during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes do not give the Trustee a
direction inconsistent with the request.

     Section 6.07.  Rights of Holders to Receive Payment.  Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, interest and Liquidated Damages, if any, on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

     Section 6.08. Collection Suit by Trustee.  If an Event of Default specified
in Section  6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest and Liquidated Damages, if any,
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and Liquidated Damages, if any, and such further amount
as shall be sufficient to cover amounts due the Trustee under Section  7.08,
including the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     Section 6.09.  Trustee May File Proofs of Claim.  The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section  7.08.  To the
extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section  7.08 out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties which the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

                                       75


     Section 6.10.  Priorities.  If the Trustee collects any money pursuant to
this Article, it shall pay out the money in the following order:

     First:  to the Trustee, its agents and attorneys for amounts due under
Section  7.08, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

     Second:  to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, interest and Liquidated Damages, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Notes for principal, premium, if any, interest and Liquidated Damages,
respectively; and

     Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section  6.10 upon five Business Days prior notice to
the Company.

     Section 6.11.  Undertaking for Costs.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section  6.06, or a suit by
Holders of more than 10% in aggregate principal amount of the then Outstanding
Notes.

     Section 6.12.  Restoration of Rights and Remedies.  If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture or any Note and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case the Company, any other obligor upon the Notes, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

     Section 6.13.  Rights and Remedies Cumulative.  No right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 6.14.  Waiver of Stay, Extension or Usury Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time

                                       76


hereafter in force, that would prohibit or forgive the Company from paying all
or any portion of the principal of (or premium, if any), interest or Liquidated
Damages, if any, on the Notes contemplated herein or in the Notes or that may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenant that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.


                                   ARTICLE 7
                                  THE TRUSTEE

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.

                                       77


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

     Section 7.02.  Notice of Defaults.  (a) Within 90 days after the occurrence
of any Default, the Trustee shall transmit by mail to all Holders, as their
names and addresses appear in the Register, notice of such Default hereunder
actually known to the Trustee unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium (if any) or interest and Liquidated Damages, if
any, on, any Note, the Trustee may withhold such notice if and so long as the
board of directors, the executive committee or a trust committee of Responsible
Officers of the Trustee determines that the withholding of such notice is not
opposed to the interests of the Holders.

     (b) The Trustee shall not be required to take notice or be deemed to have
notice or knowledge of any event or of any Default (except default in the
payment of monies to the Trustee which are required to be paid to the Trustee on
or before a specified date or within a specified time after receipt by the
Trustee of a notice or a certificate which was in fact received), unless the
Trustee shall receive from the Company or a Holder a notice stating that the
same has occurred and is continuing, and specifying the same, and in the absence
of such notice the Trustee may conclusively assume that the same does not exist,
except as aforesaid.

     Section 7.03.  Certain Rights of Trustees.  Subject to the provisions of
Section 7.01:

     (i)  the Trustee may conclusively rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

     (ii)  any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or a Company Order thereof, and any
resolution of any Person's board of directors (or any committee thereof) shall
be sufficiently evidenced if certified by an Officer of such Person as having
been duly adopted and being in full force and effect on the date of such
certificate;

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

     (iv)  the Trustee may consult with counsel of its selection and the written
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

                                       78


     (v)  in case an Event of Default occurs and is continuing, the Trustee
shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Holders pursuant
to this Indenture, unless such Holders shall have offered to the Trustee
security or indemnity satisfactory to it against any loss, liability or expense
which might be incurred by it in compliance with such request or direction;

     (vi)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, note, other
evidence of indebtedness or other paper or document;

perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

     (viii) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act
hereunder.

     Section 7.04.  Not Responsible for Recitals or Issuance of Notes.  The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder and that the
statements made by it in a Statement of Eligibility and Qualification on Form T-
1 supplied to the Company in connection with the registration of any Notes
issued hereunder will be true and accurate subject to the qualifications set
forth therein. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of the Notes or the
proceeds thereof.

     Section 7.05. Trustee's Disclaimer. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company' use of the proceeds from the Notes, it shall not be
responsible for any statement in the offering memorandum for the Notes or in the
Indenture or the Notes (other than its certificate of authentication), the acts
of a prior Trustee hereunder, or the determination as to which beneficial owners
are entitled to receive any notices hereunder.

     Section 7.06.  May Hold Notes.  The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Notes and, subject to
Section 7.09 and Section 7.14, may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

                                       79


     Section 7.07.  Money Held in Trust.  Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.

     Section 7.08.  Compensation and Reimbursement. The Company agrees:

     (a) to pay to the Trustee from time to time such compensation as the
Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

     (b)  to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses, advances and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad
faith; and

     (c)  to indemnify the Trustee and any predecessor Trustee for, and to hold
it harmless against, any loss, damage, claims, liability or expense (including
taxes, other than taxes based on the income of the Trustee) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this trust, including the reasonable costs and
expenses of defending itself against any claim (whether asserted by the Company,
a Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

     The Company' payment obligations pursuant to this Section 7.08 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(g) or 6.01(h), the
expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the TIA, within 90 days the Trustee
shall either eliminate such conflicting interest, apply to the SEC for
permission to continue as Trustee with such conflicting interest, or resign, to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. To the extent permitted by such Act, the Trustee shall
not be deemed to have a conflicting interest by virtue of being a trustee under
this Indenture with respect to Original Notes and Additional Notes, or a trustee
under any other indenture between the Company and the Trustee.

     Section 7.10. Corporate Trustee Required; Eligibility. (a) There shall at
all times be one (and only one) Trustee hereunder. The Trustee shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $100,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 7.10
and to the extent permitted by the TIA, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee

                                       80


shall cease to be eligible in accordance with the provisions of this Section
7.10, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

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

     (b)  The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 7.12 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 7.12 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the Trustee being removed may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If at any time:

     (i)  the Trustee shall fail to comply with Section 7.09 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
for at least six months, or

     (ii)  the Trustee shall cease to be eligible under Section 7.10 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

     (iii)  the Trustee shall become incapable of acting or shall be adjudged
bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B) subject
to Section 6.11, any Holder who has been a bona fide Holder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee or Trustees.

     (d)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor Trustee and shall comply with the applicable
requirements of Section 7.12. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of

                                       81


such appointment in accordance with the applicable requirements of Section 7.12,
become the successor Trustee and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner required by
Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide
Holder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     (e)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.10. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

     Section 7.12.  Acceptance of Appointment by Successor.  (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

     (b)  Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to above.

     (c)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

     Section 7.13.  Merger, Conversion, Consolidation or Succession to Business.
(a) Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

     Section 7.14.  Preferential Collection of Claims Against the Company.  (a)
If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Notes), the Trustee shall be subject to the provisions of
the TIA regarding the collection of claims against the Company (or any such
other obligor).

                                       82


     Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Company to authenticate the Notes. Any
such appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer, a copy of which instrument shall be promptly furnished to
the Company. Unless limited by the terms of such appointment, an Authenticating
Agent may authenticate Notes whenever the Trustee may do so. Each reference in
this Indenture to authentication (or execution of a certificate of
authentication) by the Trustee includes authentication (or execution of a
certificate of authentication) by such Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders as of such Regular Record Date, and

     (ii)  at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company of any such 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;

provided, however, that if and so long as the Trustee shall be the Registrar, no
such list need be furnished pursuant to this Section 8.01.

     (b)  The Company will promptly notify the Trustee when any Notes are listed
on any stock exchange and of any delisting thereof.

     Section 8.02.  Preservation of Information; Communications to Holders.  (a)
The Trustee shall preserve, in as current a form as is reasonably 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 Company, the
Trustee or any other Person shall be under any responsibility with regard to the
accuracy of such list. The Trustee may destroy any list furnished to it as
provided in Section 8.01 upon receipt of a new list so furnished.

     (b)  The rights of Holders to communicate with other Holders with respect
to their rights under this Indenture or under the Notes, and the corresponding
rights and privileges of the Trustee, shall be as provided by the TIA.

                                       83


     (c)  Every Holder, by receiving and holding the same, agrees with the

of either of them shall be held accountable by reason of any disclosure of
information as to names and addresses of Holders made pursuant to the TIA.

     Section 8.03.  Reports by Trustee.  (a)  The Trustee shall transmit to
Holders such reports concerning the Trustee and its actions under this Indenture

within 60 days after each May 15, following the date of this Indenture deliver
to Holders a brief report, dated as of such May 15, which complies with the
provisions of such Section 313(a).  A copy of each such report shall, at the
time of such transmission to Holders, be filed by the Trustee with each stock
exchange, if any, upon which any Notes are listed, with the SEC and with the
Company.



                                   ARTICLE 9

any Holder, the Company and the Trustee may enter into one or more indentures
supplemental hereto, for any of the following purposes:

     (i)  to cure any ambiguity, omission, defect or inconsistency,

     (ii) to provide for the assumption by a successor of the obligations of the
Company under this Indenture,

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

     (vii)  to make any change that does not adversely affect the rights of any

with the written consent of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Notes.

     (b)  Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not (with respect to any Notes held by a non-
consenting Holder):

     (i)  change the Stated Maturity of the principal of, or any installment of
interest on, any Note,

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

provided that no modification or change may be made to any provision of this
Indenture adversely affecting the rights of any holder of Senior Indebtedness
then outstanding unless the holders of such Senior Indebtedness (or their
Representative) consent to such modification or change.

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

     (d)  After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,

defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by the
Company and that such amendment, supplement or waiver is a valid and binding
agreement of the Company, enforceable against it in accordance with its terms
(subject to customary conditions).

     Section 9.04.  Revocation and Effect of Consents.  (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of that Note or any
Note that evidences all or any part of the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. Subject to the
following paragraph of this Section 9.04, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note by notice to the Trustee or the
Company received by the Trustee or the Company, as the case may be, before the
date on which the Trustee receives an Officer's Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver as set forth in Section 1.08.

     (b)  After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (i)
through (viii) of

                                       86


Section 9.02(b). In that case, the amendment, supplement or waiver shall bind
each Holder of a Note who has consented to it and every subsequent Holder of
such Note or any Note that evidences all or any part of the same debt as the
consenting Holder's Note.

     Section 9.05.  Conformity with TIA.  (a) Every amendment or supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the TIA as then in effect.

     Section 9.06.  Notation on or Exchange of Notes.  (a)  If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Company and in accordance with the specific written direction of the
Company) request the Holder to deliver its Note to the Trustee. The Trustee
shall (if required by the Company and in accordance with the specific written
direction of the Company) place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Company or the
Trustee so determines, the Company in exchange for the Note shall issue and the
Trustee shall authenticate a new Note that reflects the changed terms. Failure
to make the appropriate notation or issue a new Note shall not affect the
validity and effect of such amendment, supplement or waiver.

any partial redemption, selection of the Notes for redemption will be made not
more than 60 days prior to the Redemption Date by the Trustee in compliance with
the requirements of the principal national securities exchange, if any, on which

redemption, the portion of the principal amount thereof to be redeemed. On and
after the Redemption Date, interest and Liquidated Damages will cease to accrue
on Notes or portions thereof called for redemption.

     (b)  For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Notes shall relate, in

conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note.

     Section 10.06. Deposit of Redemption Price. (a) On or prior to 10:00 a.m.,
New York City time on any Redemption Date, the Company shall deposit with the

4.03) an amount of money sufficient to pay the Redemption Price of, and any
accrued and unpaid interest and Liquidated Damages, if any, on, all the Notes or
portions thereof which are to be redeemed on that date.

Price or any Paying Agent is prohibited from paying the Redemption Price
pursuant to the terms of this Indenture) such Notes shall cease to bear interest
and Liquidated Damages. Upon surrender of such Notes for redemption in
accordance with such notice, such Notes shall be paid by the Company at the
Redemption Price. Installments of interest and Liquidated Damages, if any, whose
Interest Payment Date is on or prior to the Redemption Date shall be payable to
the Holders of such Notes registered as such on the relevant Regular Record
Dates according to their terms and the provisions of Section 3.07.

on Notes called for redemption shall have been made available in accordance with
Section 10.06, the Notes (or the portions thereof) called for redemption will
cease to accrue interest and Liquidated Damages and the only right of the
Holders of such Notes (or portions thereof) will be to receive payment of the
Redemption Price of, and subject to the last sentence of Section 10.07(a), any
accrued and unpaid interest and Liquidated Damages, if any, on such Notes (or
portions thereof) to the Redemption Date. If any Note (or portion thereof)
called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest
and Liquidated Damages from the Redemption Date at the rate borne by the Note
(or portion thereof).

     Section 10.08. Notes Redeemed in Part. Any Note that is to be redeemed only
in part shall be surrendered at a Place of Payment (with, if the Company or the

thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Note without service charge, a new Note or Notes, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Note so
surrendered.

of and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture, when

     (i)  either

     (b)  Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.08 and, if money shall
have been deposited with the Trustee pursuant to clause (ii) of Section
11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

money need not be segregated from other funds except to the extent required by
law.

                       DEFEASANCE AND COVENANT DEFEASANCE

     Section 12.01.  Option of the Company to Effect Defeasance or Covenant
Defeasance.  The Company may at its option by a Board Resolution, at any time,
elect to have either Section 12.02 or Section 12.03 applied to the Outstanding
Notes upon compliance with the conditions set forth below in this Article 12.

     Section 12.02.  Legal Defeasance and Discharge.  Upon the exercise by the
Company under Section 12.01 of the option applicable to this Section 12.02, the
Company shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this
Section 12.02, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages on such Notes when such payments are
due, (ii) the obligations of the Company with respect to such Notes under
Sections 1.06, 2.03, 3.03, 3.04, 3.05, 3.06, 3.13, 3.14, 4.01, 4.02, 4.03 and
12.05 hereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Company in connection therewith
and with this Article 12.  Subject to compliance with this Article 12, the
Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 hereof with respect to the
Notes.

     Section 12.03. Covenant Defeasance. Upon the exercise by the Company under
Section 12.01 of the option applicable to this Section 12.03, the Company shall
be released from its obligations under the covenants contained in Sections 4.06
through Section 4.17, Section 4.21 and clause (iv) of Section 5.01(a) hereof
with respect to the Outstanding Notes and no Default under Section 6.01(e) and
(f) shall thereafter constitute a Default or Event of Default on the date which
is the 123rd day after the deposit referred to in Section 12.04(a); provided
that all of the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not Outstanding for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed Outstanding for all other purposes hereunder. For this
purpose, such Covenant Defeasance means that, with respect to the Outstanding
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by

                                       92


reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.01(c) or (d), but, except as specified above, the
remainder of this Indenture and such Notes shall be unaffected thereby.

     Section 12.04.  Conditions to Legal or Covenant Defeasance.  The following
shall be the conditions to application of either Section  12.02 or Section
12.03 to the Outstanding Notes:

     (a)  the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay (i) the principal of, premium, if any, and accrued interest and
Liquidated Damages, if any, on the Notes when such payments are due in
accordance with the terms of this Indenture and the Notes or (ii) in the case of
Legal Defeasance, accrued interest and Liquidated Damages, if any, on the Notes
through a scheduled redemption date and the principal of, and premium on the

such redemption will be effectuated;

     (b)  in the case of an election under Section 12.02, the Company has
delivered to the Trustee (i) either (x) an Opinion of Counsel to the effect that
Holders will not recognize income, gain or loss for Federal income tax purposes
as a result of the exercise by the Company of its option under this Article 12
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of this Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that, as a result of the creation of
the defeasance trust, the Company will not be required to register under the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund will not be subject to the effect of Section 547 of the
United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor
Law or any comparable provision of applicable law;

     (c)  in the case of an election under Section 12.03, the delivery by the
Company to the Trustee of (i) an Opinion of Counsel to the effect that, among
other things, the Holders will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit and defeasance and will be
subject to Federal income tax on the same amount and in the same manner and at
the same times as would have been the case if such deposit and defeasance had
not occurred and (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, the Company will not be required to
register under the Investment Company Act of 1940 and after the passage of 123
days

                                       93


following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or any comparable provision of applicable law;

     (d)  immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound;

     (e)  if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to the
effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge;

     (f)  the Company shall have delivered to the Trustee Officer's Certificates
stating that the deposit made by the Company pursuant to its election under
Sections 12.02 or 12.03 was not made by the Company with the intent of
preferring the Holders over the other creditors of the Company with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others; and

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

     Section 12.05.  Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions.  Subject to Section  12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section  12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

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

     Anything in this Article 12 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or U.S. Government Obligations held by it as provided in
Section  12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants

                                       94


expressed in a written certification thereof delivered to the Trustee (which may
be the opinion delivered under Section 12.04(a) hereof), are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

     Section 12.06.  Repayment to Company.  Any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest and Liquidated Damages on any
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest and Liquidated Damages has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause
to be published once, in The New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 12.07.  Reinstatement.  If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section  12.02
or 12.03, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section  12.02 or 12.03 until such time as the Trustee or Paying Agent is
permitted to apply all such amounts in accordance with Section  12.02 or 12.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest and Liquidated Damages on
any Note following the reinstatement of its Obligations, the Company shall be
subrogated to the rights of the Holder of such Note to receive such payment from
the amounts held by the Trustee or Paying Agent.

                             SUBSIDIARY GUARANTEES

optional redemption, upon repurchase following a Change of Control Offer or an
Asset Sale Offer or otherwise) of the principal of and premium, if any, and
interest and Liquidated Damages, if any, on, and all other amounts payable
under, each Note provided for under this Indenture, and the full and punctual
payment of all other amounts payable by the Company under this Indenture.  Upon
failure by the Company to pay punctually any such amount, each Subsidiary

                                       95


Guarantor shall forthwith on demand pay the amount not so paid at the place and
in the manner specified in this Indenture.

     Section 13.02.  Guarantee Unconditional.  The obligations of the Subsidiary
Guarantors hereunder shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall, to the fullest extent permitted by law,
not be released, discharged or otherwise affected by:

     (a)  any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Company under this Indenture or any Note, by
operation of law or otherwise;

     (b)  any modification or amendment of or supplement to this Indenture or
any Note; provided that any such modification which increases the obligations of
each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary
Guarantor without its consent;

     (c)  any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Company or its assets or any resulting release or
discharge of any obligation of the Company contained in this Indenture or any
Note;

     (d)  the existence of any claim, set-off or other rights which the
Subsidiary Guarantors may have at any time against the Company, the Trustee or
any other Person, whether in connection with this Indenture or any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

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

     (f)  any other act or omission to act or delay of any kind by the Company,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Subsidiary Guarantor's obligations hereunder.

     Section 13.03.  Discharge; Reinstatement.  The Subsidiary Guarantors'
obligations hereunder shall remain in full force and effect until the principal
of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
and all other amounts payable by the Company under this Indenture shall have
been paid in full.  If at any time any payment of the principal of, premium, if
any, or interest and Liquidated Damages, if any, on any Note or any other amount
payable by the Company under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, the Subsidiary Guarantors' obligations hereunder with
respect to such payment shall be reinstated as though such payment had been due
but not made at such time.

                                       96


     Section 13.04.  Waiver by the Subsidiary Guarantors.  The Subsidiary
Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and
any notice not provided for herein, as well as any requirement that at any time
any action be taken by any Person against the Company or any other Person.

     Section 13.05.  Subrogation and Contribution.  Upon making any payment with
respect to any obligation of the Company under this Article 13, the Subsidiary
Guarantor making such payment shall be subrogated to the rights of the payee
against the Company with respect to such obligation; provided that such
Subsidiary Guarantor shall not enforce either (i) any right to receive payment
by way of subrogation against the Company or against any direct or indirect
security for such obligation, or any other right to be reimbursed, indemnified
or exonerated by or for the account of the Company in respect thereof or (ii)
any right to receive payment, in the nature of contribution or for any other
reason, from any other Subsidiary Guarantor with respect to such payment, in
each case so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

     Section 13.06.  Stay of Acceleration.  If acceleration of the time for
payment of any amount payable by the Company under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of this Indenture
shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on
demand by the Trustee or the Holders.

     Section 13.07. Subordination. Each Subsidiary Guarantor's Obligations under
its Subsidiary Guarantee shall be junior and subordinated in right of payment to
any Senior Indebtedness of such Subsidiary Guarantor in the same manner and to
the same extent as the Notes are subordinated to Senior Indebtedness of the
Company pursuant to Article 14.

     Section 13.08.  Limits of Guarantees.  Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law.  To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the maximum
amount that would not render such Subsidiary Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law.

     Section 13.09.  Execution and Delivery of Note Guarantee.  To evidence its
Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
hereby agrees that this Indenture (or a supplemental indenture in the form of
Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by
one of its Officers.

     The signature of an Officer of a Subsidiary Guarantor on the Indenture
shall bind such Subsidiary Guarantor, notwithstanding that such individual has
ceased to hold such

                                       97


office prior to the authentication and delivery of any Note or did not hold such
office at the date of such Note.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Indenture on behalf of the Subsidiary Guarantors.



                                  ARTICLE 14
                                 SUBORDINATION

     Section 14.01.  Agreement to Subordinate.  The Company and the Subsidiary
Guarantors agree, and each Holder by accepting a Note agrees, any provision of
this Indenture or the Note to the contrary notwithstanding, that all obligations
owed under and in respect of the Notes and the Subsidiary Guarantees are
subordinated in right of payment, to the extent and in the manner provided in
this Article 14, to the prior payment in full of all Senior Indebtedness of the
Company and the Subsidiary Guarantors, and that the subordination of the Notes
and the Subsidiary Guarantees pursuant to this Article 14 is for the benefit of
all holders of all Senior Indebtedness of the Company and Subsidiary Guarantors
whether outstanding on the Issue Date or incurred thereafter.

     Section 14.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution
to creditors of the Company or any Subsidiary Guarantor in a liquidation or
dissolution of the Company or such Subsidiary Guarantor or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or any Subsidiary Gurantor or its property, an assignment for the
benefit of creditors or any marshalling of the Company's or a Subsidiary
Guarantor's assets and liabilities, the holders of Senior Indebtedness will be
entitled to receive payment in full in cash or cash equivalents of all
Obligations due in respect of such Senior Indebtedness (including interest after
the commencement of any such proceeding at the rate specified in the applicable
Senior Indebtedness) before the Holders of the Notes will be entitled to receive
any payment with respect to the Subordinated Note Obligations, and until all
Obligations with respect to Senior Indebtedness are paid in full in cash or cash
equivalents, any distribution to which the Holders of the Notes would be
entitled shall be made to the holders of Senior Indebtedness (except that
Holders of Senior Subordinated Notes may receive and retain Permitted Junior
Securities and payments made from the trust described in Section 12.04(a)).

     Section 14.03.  Default on Designated Senior Indebtedness.  (a) The
Companyand the Subsidiary Guarantors also may not make any payment upon or in
respect of the Subordinated Note Obligations (except in Permitted Junior
Securities or from the trust described in Section 12.04(a)) if (i) a default in
the payment of the principal of, or premium, if any, or interest on, or
commitment fees relating to, Designated Senior Indebtedness occurs and is
continuing beyond any applicable period of grace or (ii) any other default
occurs and is continuing with respect to Designated Senior Indebtedness that
permits holders of the Designated Senior Indebtedness as to which such default
relates to accelerate its maturity and the Trustee receives a notice of such
default (a "Payment Blockage Notice") from the Company or the holders of any

                                       98


Designated Senior Indebtedness. Payments on the Notes may and shall be resumed
(including the payment of any amounts previously blocked by such Payment
Blockage Notice) (x) in the case of a payment default, upon the date on which
such default is cured or waived and (y) in case of a nonpayment default, the
earlier of the date on which such nonpayment default is cured or waived or 179
days after the date on which the applicable Payment Blockage Notice is received,
unless the maturity of any Designated Senior Indebtedness has been accelerated.
No new period of payment blockage may be commenced unless and until 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been waived or cured for a period of not less than 90 days.

     To the extent any payment of Senior Indebtedness (whether by or on behalf
of the Company or the Subsidiary Guarantors, as proceeds of security or
enforcement of any right of setoff or otherwise) is declared to be fraudulent or
preferential, set aside or required to be paid to any receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then
if such payment is recovered by, or paid over to, such receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person, the Senior
Indebtedness or part thereof originally intended to be satisfied shall be deemed
to be reinstated and outstanding as if such payment had not occurred.  To the
extent the obligation to repay any Senior Indebtedness is declared to be
fraudulent, invalid, or otherwise set aside under any bankruptcy, insolvency,
receivership, fraudulent conveyance or similar law, then the obligation so
declared fraudulent, invalid or otherwise set aside (and all other amounts that
would come due with respect thereto had such obligation not been so affected)
shall be deemed to be reinstated and outstanding as Senior Indebtedness for all
purposes hereof as if such declaration, invalidity or setting aside had not
occurred.

     (b)  Notwithstanding anything to the contrary in Section 14.02 or this
Section 14.03, Holders may continue to receive payments from any trust
established pursuant to Section 12.04 prior to occurrence of an event
prohibiting payment of or on the Notes.

     Section 14.04. When Distributions Must Be Paid Over. If the Company or any
Subsidiary Guarantor shall make any payment to the Trustee on account of the
principal of, or premium, if any, or interest and Liquidated Damages, if any,
on, the Notes, or the Holders shall receive from any source any payment on
account of the principal of, premium, if any, or interest and Liquidated
Damages, if any, on, the Notes or any obligation in respect of the Notes, at a
time when such payment is prohibited by this Article 14, the Trustee or such
Holders shall hold such payment in trust for the benefit of, and shall pay over
and deliver to, the holders of the Senior Indebtedness of the Company or such
Subsidiary Guarantor (pro rata as to each of such holders on the basis of the
respective amounts of such Senior Indebtedness held by them) or their
Representative, as their respective interests may appear, for application to the
payment of all outstanding Senior Indebtedness of such Company or Subsidiary
Guarantor until all such Senior Indebtedness has been paid in full, after giving
effect to all other payments or distributions to, or provisions made for, the
holders of Senior Indebtedness of such Company or Subsidiary Guarantor.

                                       99


     With respect to the holders of Senior Indebtedness of the Company and
Subsidiary Guarantors, the Trustee undertakes to perform only such obligations
on its part as are specifically set forth in this Article 14, and no implied
covenants or obligations with respect to any holders of the Senior Indebtedness
of the Company and the Subsidiary Guarantors shall be read into this Indenture
against the Trustee.  The Trustee shall not be deemed to owe any fiduciary duty
to the holders of the Senior Indebtedness of the Company and the Subsidiary
Guarantors, and shall not be liable to any holders of such Senior Indebtedness
if the Trustee shall pay over or distribute to, or on behalf of, Holders, the
Company, Subsidiary Guarantors or any other Person, money or assets to which any
holders of such Senior Indebtedness are entitled pursuant to this Article 14,
except if such payment is made at a time when a Responsible Officer has actual
knowledge that the terms of this Article 14 prohibit such payment.

     Section 14.05.  Notice.  Neither the Trustee nor the Paying Agent shall at
any time be charged with the knowledge of the existence of any facts that would
prohibit the making of any payment to or by the Trustee or Paying Agent under
this Article 14 unless and until the Trustee or Paying Agent shall have received
written notice thereof from the Company, a Subsidiary Guarantor or one or more
holders of the Senior Indebtedness of the Company or Subsidiary Guarantor or a
representative of any holders of such Senior Indebtedness; and, prior to the
receipt of any such written notice, the Trustee or Paying Agent shall be
entitled to assume conclusively that no such facts exist; provided that if a
Responsible Officer of the Trustee shall not have received the notice provided
for in this Section 14.05 at least one Business Day prior to the date such
payment is due pursuant to the terms hereof, then, notwithstanding anything
herein to the contrary, the Trustee shall have full power and authority to make
such payment and shall not be affected by any notice to the contrary which may
be received by it within one Business Day prior to such date (it being
understood that nothing contained in this Section 14.05 shall limit the rights
of the holders of the Senior Indebtedness of the Company and the Subsidiary
Guarantors to recover any payment pursuant to Section 14.04). The Trustee shall
be entitled to rely on the delivery to it of written notice by a Person
representing itself to be a holder of the Senior Indebtedness of the Company or
a Subsidiary Guarantor (or a Representative thereof) to establish that such
notice has been given.  In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any person as a
holder of Senior Indebtedness of the Company or any Subsidiary Guarantor to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of such Senior Indebtedness held by such person,
the extent to which such person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such person under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment which it may be required to make for the benefit of such person pursuant
to the terms of this Indenture pending judicial determination as to the rights
of such person to receive such payment.

     The Company and the Subsidiary Guarantors shall promptly notify the Trustee
and the Paying Agent in writing of any facts they know that would cause a
payment of principal of, premium, if any, or interest and Liquidated Damages, if
any, on, the Notes or any other obligation in respect of the Notes to violate
this Article 14, but failure to give such notice shall not affect the
subordination of the Notes to the Senior Indebtedness of

                                      100


the Company and the Subsidiary Guarantors provided in this Article 14 or the
rights of holders of such Senior Indebtedness under this Article 14.

     Section 14.06.  Subrogation.  After all Senior Indebtedness of the Company
and the Subsidiary Guarantors has been paid in full and until the Notes are paid
in full, Holders shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of such Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness to
the extent that distributions otherwise payable to the Holders have been applied
to the payment of such Senior Indebtedness.  A distribution made under this
Article 14 to holders of the Senior Indebtedness of the Company and the
Subsidiary Guarantors that otherwise would have been made to Holders is not, as
between the Company or the relevant Subsidiary Guarantor and the Holders, a
payment by the Company or such relevant Subsidiary Guarantor on its Senior
Indebtedness.

     Section 14.07. Relative Rights. This Article 14 defines the relative rights
of Holders and holders of the Senior Indebtedness of the Company and the
Subsidiary Guarantors. Nothing in this Indenture shall: (1) impair, as between
the Company and the Subsidiary Guarantors and Holders, the obligations of the
Company and the Subsidiary Guarantors, which are absolute and unconditional, to
pay principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes in accordance with their terms; (2) affect the relative rights of
Holders and the creditors of the relevant Company or Subsidiary Guarantor other
than their rights in relation to holders of the Senior Indebtedness of the
relevant Company or Subsidiary Guarantor; or (3) prevent the Trustee or any
Holder from exercising its available remedies upon a Default or Event of
Default, subject to the rights of holders of the Senior Indebtedness to receive
distributions and payments otherwise payable to Holders.

     The failure to make a payment on account of principal of or interest and
Liquidated Damages, if any, on the Notes by reason of any provision of this
Article 14 shall not be construed as preventing the occurrence of an Event of
Default under Section 6.01.

     Section 14.08. The Company, Subsidiary Guarantors and Holders May Not
Impair Subordination. (a) No right of any holder of the Senior Indebtedness of
the Company or any Subsidiary Guarantor to enforce the subordination as provided
in this Article 14 shall at any time or in any way be prejudiced or impaired by
any act or failure to act by the Company or the relevant Subsidiary Guarantor or
by any noncompliance by the Company or the relevant Subsidiary Guarantor with
the terms, provisions and covenants of this Indenture or the Notes or any other
agreement regardless of any knowledge thereof with which any such holder may
have or be otherwise charged.

     (b)  Without in any way limiting Section 14.08(a), the holders of any
Senior Indebtedness of the Company or a Subsidiary Guarantor may, at any time
and from time to time to the extent not otherwise prohibited by this Indenture,
without the consent of or notice to any Holders, without incurring any
liabilities to any Holder and without impairing or releasing the subordination
and other benefits provided in this Indenture or the Holders' obligations to the
holders of such Senior Indebtedness, even if any Holder's right of reimbursement
or subrogation or other right or remedy is affected, impaired or

                                      101


extinguished thereby, do any one or more of the following: (i) amend, renew,
exchange, extend, modify, increase or supplement in any manner such Senior
Indebtedness or any instrument evidencing or guaranteeing or securing such
Senior Indebtedness or any agreement under which such Senior Indebtedness is
outstanding (including, but not limited to, changing the manner, place or terms
of payment or changing or extending the time of payment of, or renewing,
exchanging, amending, increasing or altering, (A) the terms of such Senior
Indebtedness, (B) any security for, or any Guarantee of, such Senior
Indebtedness, (C) any liability of any obligor on such Senior Indebtedness
(including any guarantor) or any liability incurred in respect of such Senior
Indebtedness); (ii) sell, exchange, release, surrender, realize upon, enforce or
otherwise deal with in any manner and in any order any property pledged,
mortgaged or otherwise securing such Senior Indebtedness or any liability of any
obligor thereon, to such holder, or any liability incurred in respect thereof;
(ii) settle or compromise any such Senior Indebtedness or any other liability of
any obligor of such Senior Indebtedness to such holder or any security therefor
or any liability incurred in respect thereof and apply any sums by whomsoever
paid and however realized to any liability (including, without limitation,
payment of any of the Senior Indebtedness of the Company and Subsidiary
Guarantors) in any manner or order; and (iv) fail to take or to record or
otherwise perfect, for any reason or for no reason, any lien or security
interest securing such Senior Indebtedness by whomsoever granted, exercise or
delay in or refrain from exercising any right or remedy against any obligor or
any guarantor or any other Person, elect any remedy and otherwise deal freely
with any obligor and any security for such Senior Indebtedness or any liability
of any obligor to the holders of such Senior Indebtedness or any liability
incurred in respect of such Senior Indebtedness.

     (c)  Each Holder by accepting a Note agrees not to compromise, release,
forgive or otherwise discharge the obligations with respect to such Holder's
Note unless holders of a majority of the outstanding amount of each class of
Senior Indebtedness of the Company and Subsidiary Guarantors consent to such
compromise, release, forgiveness or discharge.

     Section 14.09.  Distribution or Notice to Representative.  Whenever a
distribution is to be made, or a notice given, to holders of Senior Indebtedness
of the Company or a Subsidiary Guarantor, the distribution may be made and the
notice given to their Representative, if any.  If any payment or distribution of
the assets of the Company or a Subsidiary Guarantor is required to be made to
holders of any of the Senior Indebtedness of the Company or such Subsidiary
Guarantor pursuant to this Article 14, the Trustee and the Holders shall be
entitled to rely upon any order or decree of any court of competent
jurisdiction, or upon any certificate of a representative of such Senior
Indebtedness or a custodian, in ascertaining the holders of such Senior
Indebtedness entitled to participate in any such payment or distribution, the
amount to be paid or distributed to holders of such Senior Indebtedness and all
other facts pertinent to such payment or distribution or to this Article 14.

     Section 14.10.  Rights of Trustee and Paying Agent.  The Trustee or Paying
Agent may continue to make payments on the Notes unless prior to any payment
date it has received written notice of facts that would cause a payment of
principal of, or premium, if any, or interest and Liquidated Damages, if any,
on, the Notes to violate this Article  14.  Only the Company, Subsidiary
Guarantors, a Representative of Senior

                                      102


Indebtedness of the Company or a Subsidiary Guarantor, or a holder of Senior
Indebtedness of the Company or a Subsidiary Guarantor that has no Representative
may give such notice.

     To the extent permitted by the TIA, the Trustee in its individual or any
other capacity may hold Indebtedness of the Company and Subsidiary Guarantors
(including Senior Indebtedness) with the same rights it would have if it were
not Trustee.  Any agent of the Trustee may do the same with like rights.

     Nothing in this Article 14 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.08.

     Section 14.11.  Authorization to Effect Subordination.  Each Holder by its
acceptance thereof authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination as
provided in this Article 14, and appoints the Trustee as such Holder's attorney-
in-fact for any and all such purposes (including, without limitation, the timely
filing of a claim for the unpaid balance of the Note that such Holder holds in
the form required in any insolvency or liquidation proceeding and causing such
claim to be approved).

     If a proper claim or proof of debt in the form required in such proceeding
is not filed by or on behalf of all Holders prior to 30 days before the
expiration of the time to file such claims or proofs, then the holders or a
Representative of any Senior Indebtedness of the Company or any Subsidiary
Guarantor is hereby authorized, and shall have the right (without any duty), to
file an appropriate claim for and on behalf of the Holders.

     Section 14.12. Payment. A payment on account of or with respect to any Note
shall include, without limitation, principal, premium, interest or Liquidated
Damages with respect to or in connection with any optional redemption or
purchase provisions, any direct or indirect payment payable by reason of any
other Indebtedness or obligation being subordinated to the Notes, and any direct
or indirect payment or recovery on any claim as a Holder relating to or arising
out of this Indenture or any Note, or the issuance of any Note, or the
transactions contemplated by this Indenture or referred to herein.

                                      103


     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be

                           LYONDELL CHEMICAL COMPANY

                   10 7/8 Senior Subordinated Note due 2009


     (1)  Principal and Interest; Subordination.  The Company agrees to pay the
principal of this Note on May 1, 2009.

     The Company agrees to pay interest on the principal amount of this Note on
each Interest Payment Date, as set forth below, at the rate of 10 7/8% per
annum.

     Interest will be payable semi-annually (to the Holders of record of the
Notes (or any predecessor Notes) at the close of business on the Regular Record
Date immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing November 1, 1999.

     [The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated May 17, 1999, among the Company, the Subsidiary
Guarantors party thereto and the Initial Purchasers named therein (the
"Registration Rights Agreement"). In the event that (i) the Company or the
Subsidiary Guarantors fail to file an Exchange Offer Registration Statement with
the SEC on or prior to the 90th day after the Issue Date, (ii) if the Exchange
Offer Registration Statement is not declared effective by the SEC on or prior to
the 210th day after the Issue Date, (iii) if the Exchange Offer is not
consummated on or before the 30th business day after the Exchange Offer
Registration Statement is declared effective, (iv) the Company and the
Subsidiary Guarantors are obligated to file the Shelf Registration Statement and
fail to file the Shelf Registration Statement with the SEC on or prior to the
30th day after such filing obligation arises, (v) the Company and the Subsidiary
Guarantors are obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 60th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Notes during the periods specified
in the Registration Rights Agreement, for such time of non-effectiveness or non-
usability (each, a "Registration Default"), the Company and the Subsidiary
Guarantors agree to pay to the Holder of this Note, if affected thereby,
liquidated damages ("Liquidated Damages") in an amount equal to $0.05 per week
per $1,000 in principal amount of this Note for each week or portion thereof
that the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Notes with respect to each subsequent 90 day period until
all Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.50 per week per $1,000 in principal amount of Notes. The Company
and the Subsidiary Guarantors shall not be required to pay Liquidated Damages
for more than one


                                      A-4


Registration Default at any given time. Following the cure of all Registration
Defaults, the accrual of Liquidated Damages will cease.]./2/

     Interest on this Note will accrue from the most recent date to which
interest has been paid [on this Note or the Note surrendered in exchange
herefor]/1/ or, if no interest has been paid, from May 17, 1999; provided that,
if there is no existing default in the payment of interest and if this Note is
authenticated between a Regular Record Date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such
Interest Payment Date.  Interest will be computed on the basis of a 360-day year
of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest and Liquidated Damages, to the
extent lawful, at a rate per annum equal to 1% per annum in excess of the rate
of interest applicable to the Notes.

     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Note is issued
subject to such provisions.  Each Holder of this Note, by accepting the same,
(a) agrees to and shall be bound by such provisions, (b) authorizes and directs
the Trustee on its behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in the Indenture and (c) appoints
the Trustee its attorney-in-fact for such purpose.

     (2)  Method of Payment.  The Company will pay interest (except defaulted
interest) on the principal amount of the Notes on each May 1 and November 1 to
the Persons who are Holders (as reflected in the Register at the close of
business on the April 15 and October 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is canceled on registration of
transfer or registration of exchange after such Regular Record Date; provided
that, with respect to the payment of principal, the Company will make payment to
the Holder that surrenders this Note to any Paying Agent on or after May 1,
2009.

     The Company will pay principal, premium, if any, and interest and
Liquidated Damages, if any, in money of the United States that at the time of
payment is legal tender for payment of public and private debts.  Payments
(including principal, premium, if any, and interest and Liquidated Damages, if
any) in respect of the Notes represented by the Global Notes, the Holders of
which have given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Company will make all payments of principal, premium, if any, and interest
and Liquidated Damages, if any, at the office or agency maintained by the
Company for such purposes in The City of New York or, at the Company's option,
by mailing a check to each such Holder's registered address. If a payment date
is a date other than a Business Day, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

                                      A-5


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

     (4)  Indenture; Limitations.  The Company issued the Notes under an
Indenture dated as of May 17, 1999 (the "Indenture"), among the Company, the
Subsidiary Guarantors and The Bank of New York, as trustee (the "Trustee").
Capitalized terms herein are used as defined in the Indenture unless otherwise
indicated.  The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "TIA").  The Notes are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of all such terms.  To the extent
permitted by applicable law, in the event of any inconsistency between the terms
of this Note and the terms of the Indenture, the terms of the Indenture shall
control.

     The Notes are unsecured senior subordinated obligations of the Company. The
Indenture limits the initial aggregate principal amount of the Notes to
$500,000,000 but permits the issuance of Additional Notes in an unlimited amount
subject to compliance with the covenants contained in the Indenture and except
as may be limited by applicable law.

     (5)  Optional Redemption. The Notes may be redeemed at the option of the
Company, in whole or in part, at any time and from time to time, on or after May
1, 2004, at the following Redemption Prices (expressed in percentages of
principal amount on the relevant Redemption Date), plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date, if redeemed
during the 12-month period commencing May 1 of each of the years set forth
below:

 YEAR                         REDEMPTION PRICE

2004.........................     105.438%
2005.........................     103.625%
2006.........................     101.812%
2007 and thereafter..........    100.0000%

  Notwithstanding the foregoing, at any time prior to May 1, 2002, the Company
may redeem up to 35% of the original principal amount of the Notes, with the
proceeds of one or more Public Equity Offerings, at the redemption price
(expressed in percentages of principal amount on the relevant Redemption Date)
of 110.875% plus accrued and unpaid interest and Liquidated Damages, if any, to
the Redemption Date; provided, however, that (i) at least 65% of the aggregate
principal amount of the Notes from time to time originally issued under the
Indenture remains Outstanding and is held, directly or indirectly, by Persons
other than the Company and its Affiliates and (ii) such redemption shall occur
within 90 days of the applicable Public Equity Offering.

                                      A-6


  If less than all the Notes are to be redeemed at any time, selection of Notes
for redemption will be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a pro rata basis, by lot or by
such method as the Trustee shall deem fair and appropriate; provided that no
Notes of $1,000 or less shall be redeemed in part.

  Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder of Notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed.  A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if any, cease to accrue on Notes or portions of them called
for redemption.

  (6)  Repurchase upon a Change in Control and Sale of Assets.  Upon the
occurrence of (a) a Change in Control, each Holder shall have the right to
require that the Company repurchase such Holder's Notes at a purchase price in
cash equal to 101% of the principal amount thereof on the date of purchase, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase and (b) an Asset Sale, the Company may be obligated to make an offer to
purchase on a pro rata basis from the Holders the Notes with the Excess Proceeds
of such Asset Sales at a purchase price equal to 100% of the principal amount of
such Notes plus accrued interest and Liquidated Damages, if any, to the date of
purchase.

  (7)  Denominations; Transfer; Exchange.  The Notes are in fully registered
form without coupons, in denominations of $1,000 and any integral multiples of
$1,000. A Holder may register the transfer or exchange of Notes in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture.

  (8)  Persons Deemed Owners.  A Holder may be treated as the owner of a Note
for all purposes.

  (9)  Unclaimed Money.  If money for the payment of principal, premium, if any,
or interest and Liquidated Damages, if any, remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the Company at its
written request.  After that, Holders entitled to the money must look to the
Company for payment, unless an abandoned property law designates another Person,
and all liability of the Trustee and such Paying Agent with respect to such
money shall cease.

  (10) Discharge Prior to Redemption or Maturity.  If the Company irrevocably
deposits, or causes to be deposited, with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of and  premium, if
any, and accrued interest and Liquidated Damages on the Notes (a) to redemption
or maturity, the Company will be discharged from the Indenture and the Notes,
except in certain

                                      A-7


circumstances for certain sections thereof, and (b) to redemption or maturity,
the Company will be discharged from certain covenants set forth in the
Indenture.

  (11) Amendment; Supplement; Waiver.  Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
Outstanding, and any existing Default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding.  Without notice to or the consent of any
Holder, the parties thereto may amend the Indenture or the Notes to the extent
set forth in the Indenture.

  (12) Restrictive Covenants.  The Indenture contains certain covenants,
including, without limitation, covenants with respect to the following matters:
(i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted
Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with
Affiliates; (vi) Liens; (vii) Senior Subordinated Indebtedness; (viii)
repurchase of Notes upon a Change in Control; (ix) Sale and Leaseback
Transactions; (x) Subsidiary Guarantees; and (xi) consolidation, merger and sale
of assets.  Within 120 days after the end of each fiscal year, the Company must
report to the Trustee on compliance with such limitations.

  (13) Successor Persons.  When a successor person or other entity (other than a
Subsidiary of the Company) assumes all the obligations of its predecessor under
the Notes and the Indenture, the predecessor person will be released from those
obligations.

  (14) Remedies for Events of Default.  If an Event of Default (other than an
Event of Default specified in Section 6.01(g) or (h) of the Indenture that
occurs with respect to the Company or a Subsidiary Guarantor) occurs and is
continuing under this Indenture, then in every such case the Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding Notes,
by written notice to the Company (and to the Trustee if such notice is given by
the Holders), may, and the Trustee at the written request of such Holders shall,
declare the principal of, premium, if any, and accrued interest and Liquidated
Damages, if any, on all of the Outstanding Notes to be immediately due and
payable.  Upon a declaration of acceleration, such principal of, premium, if
any, and accrued interest and Liquidated Damages, if any, shall be immediately
due and payable. If an Event of Default specified in  Section 6.01(g) or (h) of
the Indenture occurs with respect to the Company or a Subsidiary Guarantor, the
principal of, premium, if any, and accrued interest and Liquidated Damages, if
any, on the Outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.  The Holders of at least a majority in aggregate principal amount of the
Outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if (1) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes that have become due solely by such declaration of acceleration,
have been cured or waived and (2) the recission would not conflict with any
judgment or decree of a court of competent jurisdiction.

  Holders may not enforce the Indenture, the Notes or the Subsidiary Guarantees
except as provided in the Indenture.  The Trustee may require security or
indemnity

                                      A-8


satisfactory to it before it enforces the Indenture, the Notes or the Subsidiary
Guarantees. The Holders of at least a majority in aggregate principal amount of
the Notes then Outstanding may direct the Trustee in the exercise of any trust
or power in accordance with the terms of the Indenture.

  (15) Subsidiary Guarantees.  Each Subsidiary Guarantor irrevocably and
unconditionally guarantees jointly and severally, on an unsecured senior
subordinated basis, the full and punctual payment (whether at Stated Maturity,
upon acceleration, optional redemption, upon repurchase following a Change of
Control Offer or an Asset Sale Offer or otherwise) of the principal of, premium,
if any, and interest and Liquidated Damages, if any, on, and all other amounts
payable under, this Note provided for under this Indenture, and the full and
punctual payment of all other amounts payable by the Company under the
Indenture; provided that, notwithstanding anything to the contrary herein, the
aggregate amount of the Obligations guaranteed under the Indenture by any
Subsidiary Guarantor shall be limited in amount to the maximum amount that would
not render such Subsidiary Guarantor's obligations subject to avoidance under
the applicable fraudulent conveyance provisions of the United States Bankruptcy
Code or any comparable provision of any applicable state law.

  Each Subsidiary Guarantor's obligations under its Subsidiary Guarantee shall
be subordinated in right of payment to all Senior Indebtedness of such
Subsidiary Guarantor to the extent and in the manner provided in the Indenture.
Each Holder of this Note, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on its behalf
to take such action as may be necessary or appropriate to effectuate the
subordination as provided in the Indenture and (c) appoints the Trustee its
attorney-in-fact for such purpose.

  (16) 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.

  (17) Trustee Dealings with Company.  The Trustee under the Indenture, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may make loans to, accept deposits from, perform services for, and otherwise
deal with, the Company and its Affiliates as if it were not the Trustee.

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

  (19) Abbreviations.  Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A
(= Uniform Gifts to Minors Act).

  (20) Governing Law. This Note shall be governed by and construed in accordance
with the laws of the State of New York, without giving effect to any principles

                                      A-9


of conflict of laws to the extent that the application of the law of another
jurisdiction is required thereby.

          The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture. Requests may be made to the Company, One
