                               KOMAG, INCORPORATED

                          SENIOR SECURED NOTES DUE 2007

               Capitalized terms used herein shall have the meanings assigned to
them in the Indenture referred to below unless otherwise indicated.

               1. Principal. The Company promises to pay principal on this Note
in an amount equal to ________________ ($_________), such amount payable
quarterly in an amount equal to $________ [1/17th OF THE ORIGINAL CASH PAY
PORTION OF THIS NOTE] (each, a "PRINCIPAL PAYMENT") on January 15, April 15,
July 15 and October 15 of each year, or if any such day is not a Business Day,
on the next succeeding Business Day (each, a "PRINCIPAL PAYMENT DATE"),
beginning on July 15, 2003; provided, however, that the entire unpaid principal
amount of this Note shall be due and payable on _____, 2007.

               2. Interest. The Company promises to pay interest on (i) the Cash
Pay Portion of this Note (as such amount may be adjusted from time to time
pursuant to the terms of this Note) at the greater of (x) 8% per annum and (y)
3% over the "prime rate" as published in The Wall Street Journal, Western
Edition ("CASH PAY INTEREST") (it being understood that the Company shall
determine the applicable Cash Pay Interest rate and provide such rate to the
Paying Agent) and (ii) the PIK Portion of this Note (as such amount may be
adjusted from time to time pursuant to the terms of this Note) at 12% per annum
("PIK INTEREST"), each from July 15, 2002 until maturity. The Company shall pay
interest monthly in arrears on the 15th day of each month, or if any such day is
not a Business Day, on the next succeeding Business Day (each, an "INTEREST
PAYMENT DATE"). Interest on this Note shall accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
original issuance on ____ __, 2002; provided, that if there is no existing
Default or Event of Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be July 15, 2002. Interest shall be computed on the basis of
a 360-day year of twelve 30-day months.

               3. Method of Payment.

               (a) The Company shall pay Cash Pay Interest on this Note (except
default interest) to the Person who is the registered Holder of this Note at the
close of business on the 1st day of the month that includes the Interest Payment
Date, even if this Note is canceled after such record date and on or before such
Interest Payment Date, except as provided in Section 2.12 of the Indenture with
respect to default interest.

(b) The Company shall make each Principal Payment on this Note to the Person who
is the registered Holder of this Note at the close of business on the 1st day of
the month that includes the Principal Payment Date, even if this Note is
canceled after such record date and on or before such Principal Payment Date.
Upon each Principal Payment, the outstanding principal

                                      A-5
<PAGE>

amount of this Note and the Cash Pay Portion of this Note shall be reduced by
the amount of such Principal Payment.

               (c) On each Interest Payment Date, the outstanding principal
amount of this Note and the PIK Portion of this Note shall be automatically
increased by the amount of PIK Interest to be paid on such Interest Payment Date
and the Company shall be deemed to have made such PIK Interest payment on such
Interest Payment Date. On or prior to the date of the issuance of this Note, the
Company shall have provided the Trustee with a schedule (the "PIK Interest
Schedule") setting forth the PIK Portion of this Note as of each Interest
Payment Date, in each case after taking account of the PIK Interest due on such
Interest Payment Date. If the payment of PIK Interest by addition to principal
in the manner provided above shall for any reason be prohibited by applicable
law on any Interest Payment Date, the Company shall be obligated, instead, to
deliver an additional Note, substantially in the form of Exhibit A to the
Indenture, to the Holder of this Note in an aggregate principal amount equal to
the PIK Interest due on this Note on such Interest Payment Date, and the
requirements set forth in the Indenture and this Note as to minimum
denominations of $100 shall not apply to any such additional Notes.

               (d) This Note shall be payable as to principal, premium, Cash Pay
Interest and default interest, if any, at the office or agency of the Company
maintained for such purpose in the Borough of Manhattan, the City of New York,
maintained for such purposes, or, at the option of the Company, payment of Cash
Pay Interest and default interest, if any, may be made by check mailed to the
Holder at its address set forth in the register of Holders, and provided that
payment by wire transfer of immediately available funds shall be required with
respect to principal of and Cash Pay Interest, default interest, if any, and
premium on, this Note if the Holder thereof shall have provided wire transfer
instructions to the Company and the Paying Agent 5 days prior to record date.
Such wire transfer instructions will remain in effect until receipt of written
direction changing or rescinding instructions. Such payment shall be in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.

               4. Paying Agent and Registrar. Initially, The Bank of New York,
the Trustee under the Indenture, shall act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity.

               5. Indenture and Collateral Documents. The Company issued this
Note under an Indenture dated as of _____, 2002 (the "INDENTURE") by and between
the Company and the Trustee. The terms of this Note include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S.C. Sections 77aaa-77bbbb). This Note
is subject to all such terms, and Holders are referred to the Indenture and such
Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are secured obligations of
the Company limited to $139,118,000 in aggregate principal amount (without
taking into account any increases in principal amount of the Notes as a result
of the payment of PIK interest). The Notes are secured by the Collateral as set
forth in the Collateral Documents. By its acceptance hereof, Holder acknowledges
and agrees that the Trustee has entered into the Liquidity Facility
Intercreditor

                                      A-6
<PAGE>

Agreement pursuant to which the liens granted to the Trustee to secure the
indebtedness evidenced hereby are subordinated to the liens securing the
indebtedness under the Liquidity Facility.

               6. Optional Redemption. The Company may redeem all or a part of
this Note upon not less than 30 nor more than 60 days' notice, at the principal
amount outstanding thereof, plus, in each case, accrued interest thereon, to the
applicable redemption date (subject to the right of Holders on the relevant
record date to receive interest due on the related interest payment date). If
less than all of the Notes are to be redeemed at any time of redemption, the
amount paid to redeem any Note shall (i) first, be applied to the Cash Pay
Portion of such Note (including accrued interest thereon) until the Cash Pay
Portion of such Note (including accrued interest thereon) shall have been paid
in full with such amounts to be applied to the Principal Payments in inverse
order of the date on which such Principal Payments are due, and (ii) second, be
applied to the PIK Portion of such Note (including accrued interest thereon)
with such amounts to be applied to the principal payments on the Notes in
inverse order of the date on which such principal payments are due.

               7. Mandatory Redemption. At any time the sum of (x) the aggregate
amount of all Remaining Capital Raising Proceeds and (y) the aggregate amount of
all Remaining Asset Sale Proceeds exceeds $5 million (each, a "MANDATORY
REDEMPTION TRIGGERING EVENT"), the Company shall, within 60 days of such
Mandatory Redemption Triggering Event, redeem the maximum principal amount of
the Notes that may be redeemed out of such Remaining Capital Raising Proceeds
and/or the Remaining Asset Sale Proceeds upon not less than 15 nor more than 60
days' notice, at the principal amount outstanding thereof plus accrued interest
thereon, to the applicable redemption date (subject to the right of Holders on
the relevant record date to receive interest due on the related interest payment
date). If less than all of the Notes are to be redeemed at any time of
redemption, the amount paid to redeem any Note shall (i) first, be applied to
the Cash Pay Portion of such Note (including accrued interest thereon) until the
Cash Pay Portion of such Note (including accrued interest thereon) shall have
been paid in full, with such amounts to be applied to the Principal Payments in
inverse order of the date on which such Principal Payments are due, and (ii)
second, be applied to the PIK Portion of such Note (including accrued interest
thereon) with such amounts to be applied to the principal payments in inverse
order of the date on which such principal payments are due. Pending the final
application of any Remaining Capital Raising Proceeds or Remaining Asset Sale
Proceeds, the Company or the applicable Subsidiary, as the case may be, may
invest such proceeds in Cash which shall be pledged to the Trustee as security
for the Holders of the Notes and, subject to the terms of the Senior Notes
Intercreditor Agreement, the Junior Notes. Upon any redemption payment, each of
the Cash Pay Portion and the PIK Portion of this Note shall be reduced by the
amount of such redemption payment to be applied to such Portion and the
outstanding principal amount of this Note shall be reduced by the aggregate
amount of such redemption payment.

               The Company shall not be required to make mandatory redemption
payments or sinking fund payments with respect to the Notes other than as set
forth in this paragraph 7.

               8. Notice of Redemption. Notice of redemption shall be mailed by
first class mail at least 15 days but not more than 60 days before the
redemption date to each Holder whose Notes are to be redeemed at its registered
address. No Notes in amounts of $100 or less shall be

                                      A-7
<PAGE>

redeemed in part. Notes selected shall be in amounts of $100 or whole multiples
of $100; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of the Notes held by such Holder, even if not a
multiple of $100, shall be redeemed. On and after the redemption date, interest
shall cease to accrue on this Note or portions thereof called for redemption.

               If the Company elects to redeem this Note or is required to
redeem this Note pursuant to the terms hereof and the Indenture, the Company
shall furnish to the Trustee, at least 45 days before the applicable redemption
date (unless the Trustee agrees to a shorter notice period), an Officers'
Certificate setting forth a revised PIK Interest Schedule setting forth the PIK
Portion of this Note as of each Interest Payment Date, in each case after taking
account of the PIK Interest due on such Interest Payment Date, taking into
account the principal amount of this Note to be so redeemed as well as any prior
redemptions or other prepayments of principal of this Note.

               9. Denominations, Transfer, Exchange. The Notes are in registered
form without coupons in denominations of $100 and integral multiples of $100.
The transfer of this Note may be registered and this Note may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require the Holder
of this Note, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require such Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of this Note or portion of this Note selected
for redemption, except for the unredeemed portion of this Note being redeemed in
part. Also, the Company need not exchange or register the transfer of this Note
for a period of 15 days before a selection of Notes to be redeemed.

               10. Persons Deemed Owners. The registered Holder of this Note may
be treated as its owner for all purposes.

               11. Amendment, Supplement and Waiver. Subject to certain
exceptions, the Indenture, the Notes, the Liquidity Facility Intercreditor
Agreement, the Senior Notes Intercreditor Agreement or the other Collateral
Documents may be amended or supplemented with the consent of the Holders of at
least a majority in outstanding principal amount of the then outstanding Notes
voting as a single class (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, the
Notes), and any existing default or compliance with any provision of the
Indenture, the Notes, the Liquidity Facility Intercreditor Agreement, the Senior
Notes Intercreditor Agreement or the other Collateral Documents may be waived
with the consent of the Holders of a majority in outstanding principal of the
then outstanding Notes voting as a single class (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, the Notes). Without the consent of any Holder of a Note, the
Indenture, the Notes, the Intercreditor Agreement or the other Collateral
Documents may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes to make any change that would provide any additional rights
or benefits to the Holders of the Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder, to enter into additional or
supplemental Intercreditor Agreements or Collateral

                                      A-8
<PAGE>

Documents or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.

               12. Defaults and Remedies. Events of Default include: (a) default
in the payment of (i) any installment of the principal of any Note when due or
(ii) any installment of interest on any Note or other amount payable with
respect to any Note for a period of 5 consecutive days from the date when due;
(b) failure by the Company or any of its Subsidiaries to perform or comply with
the provisions described under Sections 4.10 through 4.22, 4.23(b), 4.24 through
4.27, 4.29, 4.31 and 4.32 of the Indenture; (c) failure by the Company for 30
consecutive days to comply with any other term, covenant or agreement in any
material respect, or the Company's breach of any representation or warranty in
any material respect contained in, the Indenture, the Notes, the Liquidity
Facility Intercreditor Agreement, the Senior Notes Intercreditor Agreement or
the other Collateral Documents; (d) (i) default by the Company or any of its
Subsidiaries in the payment when due (giving effect to any applicable grace
period) of any amount owing under the Liquidity Facility or the Junior Notes or
any obligation or Indebtedness (other than those specifically arising under the
Indenture) in excess of $1.0 million in aggregate amount, or (ii) fail to
observe or perform any material term, covenant or agreement contained in any
agreement governing the Liquidity Facility or the Junior Notes Indenture or
entered into pursuant thereto or any agreement for such obligation or
Indebtedness by which it is bound, in each case for such period of time as would
permit (assuming the giving of appropriate notice if required) the holder or
holders thereof or of any obligations issued thereunder accelerate the maturity
thereof; provided, however, that any default under this subsection (d) with
respect to the Liquidity Facility shall be deemed cured if such default shall
have been cured by the Company or unconditionally waived by the lenders or the
holders of the Junior Notes thereunder, as applicable, pursuant to the terms
thereof; (e) the entering of one judgment or decree against the Company or any
of its Subsidiaries involving a liability (to the extent not paid or covered by
insurance or the third party indemnity of a solvent indemnitor) equal to or
greater than $5.0 million or the entering of one or more judgments or decrees
involving in the aggregate a liability (to the extent not paid or covered by
insurance or the third party indemnity of a solvent indemnitor) equal to or
greater than $10.0 million and, in all such cases, all such judgments or decrees
shall not have been vacated, discharged, or stayed or bonded pending appeal
within thirty (30) days from the entry thereof; (f) certain events relating to
the Company, its ERISA Affiliates and their respective Pension Plans as more
fully described in the Indenture; (g) the institution against the Company, or
any of its Subsidiaries, of any proceeding for which forfeiture (to the extent
not paid or covered by insurance or the third party indemnity of a solvent
indemnitor) of any property equal to or greater than $5.0 million is a potential
penalty and such proceeding shall not have been vacated or discharged within
thirty (30) days of its institution; and (h) certain events of bankruptcy or
insolvency with respect to the Company or any of its Subsidiaries (other than
any Non-Material Subsidiaries) as more fully described in the Indenture.

               In the case of an Event of Default arising from certain events of
bankruptcy or insolvency with respect to the Company or any of its Subsidiaries
(other than any Non-Material Subsidiaries) or upon the acceleration of any
outstanding principal amount owing under the Liquidity Facility, all outstanding
Notes will become due and payable without further action or notice. If any other
Event of Default occurs and is continuing, the Trustee or the Holders of at
least a majority in outstanding principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately. Holders may not
enforce the Indenture or the

                                      A-9
<PAGE>

Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in outstanding principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or Interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate outstanding principal amount of
the Notes then outstanding by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of Interest on, or the principal of, the Notes.

               The Company is required to deliver to the Trustee quarterly a
statement regarding compliance with the Indenture. Upon becoming aware of any
Default or Event of Default, the Company is required to deliver to the Trustee a
statement specifying such Default or Event of Default.

               13. Trustee Dealings with Company. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

               14. Authentication. This Note shall not be valid until
authenticated by the manual or facsimile signature of the Trustee or an
authenticating agent.

               15. 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).

               16. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

               The Company shall furnish to the Holder of this Note upon written
request and without charge a copy of the Indenture, the Liquidity Facility
Intercreditor Agreement, the Senior Notes Intercreditor Agreement and/or any
Collateral Documents. Requests may be made to:

               (a) General. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto. The Notes
may have notations, legends or endorsements required by law, stock exchange rule
or usage. Each Note shall be dated the date of its authentication. The Notes
shall be issued only in registered form without coupons. Notes issued on the
date of original issuance of Notes hereunder shall be issued only in minimum
denominations of $100 and larger integral multiples of $1.00. As to any Note
issued thereafter (including on any exchange or transfer or any issuance of
Notes in accordance with Section 4.1) there shall be no minimum denomination or
integral multiple requirements.

               The terms and provisions contained in the Notes shall constitute,
and are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to

                                       22
<PAGE>

However, to the extent any provision of any Note conflicts with the express
provisions of this Indenture, the provisions of this Indenture shall govern and
be controlling.

               (b) Global Note. The Note issued in global form shall be
substantially in the form of Exhibit A hereto (including the Global Note Legend
thereon and the "Schedule of Exchanges of Interests in the Global Note" attached
thereto). Definitive Notes shall be issued substantially in the form of Exhibit
A hereto (but without the Global Note Legend thereon and without the "Schedule
of Exchanges of Interests in the Global Note" attached thereto). The Global Note
shall represent such of the outstanding Notes as shall be specified therein and
shall provide that it shall represent the aggregate Stated Principal Amount
(without taking into account any increases due to deferred interest) of
outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount at maturity of outstanding Notes represented thereby shall be
increased through the addition of deferred interest, if any, as provided in the
Notes and may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Whenever as a result of any optional or
mandatory redemption or an exchange for Definitive Notes pursuant to Section 2.6
hereof, a Global Note is redeemed, repurchased or exchanged in part, an
endorsement will be made to the Global Note so that the Stated Principal Amount
of the Global Note shall be equal to the portion thereof not so redeemed,
repurchased or exchanged (without taking into account any increase due to
deferred interest). Any endorsement of the Global Note to reflect the amount of
any increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian in accordance
with the terms hereof and of the Global Note and otherwise in accordance with
instructions given by the Holder thereof as required by Section 2.6 hereof.

               Section 2.2 Execution and Authentication. One Officer of the
Company shall sign the Notes for the Company by manual or facsimile signature.
The Company seal shall be reproduced on the Notes and may be in facsimile form.

               If an Officer of the Company whose signature is on a Note no
longer holds that office at the time a Note is authenticated, the Note shall
nevertheless be valid.

               A Note shall not be valid until authenticated by the manual
signature of the Trustee. Such signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

               The Trustee shall, upon a written order of the Company signed by
one Officer of the Company (an "AUTHENTICATION ORDER"), authenticate the Notes
for original issue up to the initial aggregate principal amount stated in
paragraph 5 of the Notes. The aggregate principal amount of Notes outstanding at
any time (without taking into account any increases due to deferred interest)
may not exceed such amount except as provided in Section 2.7 hereof.

               The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

transfer or for exchange ("REGISTRAR") and an office or agency where Notes may
be presented for payment ("PAYING AGENT"). The Registrar shall keep a register
of the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term
"Registrar" includes any co-registrar and the term "Paying Agent" includes any
additional paying agent. The Company may change any Paying Agent or Registrar
without notice to any Holder. The Company shall notify the Trustee in writing of
the name and address of any Agent not a party to this Indenture. If the Company
fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such to the extent that it determines that it may do so.
The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

               The Company initially appoints The Depository Trust Company
("DTC") to act as Depositary with respect to the Global Note.

               The Company initially appoints the Trustee to act as the
Registrar and Paying Agent and to act as Custodian with respect to the Notes.

               Section 2.4 Paying Agent to Hold Money in Trust. The Company
shall require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of Holders of the Notes or
the Trustee all money held by the Paying Agent for the payment of principal,
premium or interest on the Notes, and will notify the Trustee in writing of any
default by the Company in making any such payment. While any such default
continues, the Trustee may require a Paying Agent to pay all money held by it to
the Trustee. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent
(if other than the Company or one of its Subsidiaries) shall have no further
liability for the money. If the Company or one of its Subsidiaries acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money held by it as Paying Agent with respect to the
Notes. Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee shall serve as Paying Agent for the Notes.

               Section 2.5 Holder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of all Holders of the Notes and shall otherwise
comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company
shall furnish to the Trustee at least seven Business Days before each interest
payment date, or in the event interest is deferred pursuant to the terms of the
Notes, three days after any Record Date, and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee
may reasonably require of the names and addresses of the Holders of the Notes
and the Company shall otherwise comply with TIA Section 312(a).

               Section 2.6 Transfer and Exchange.

               (a) Transfer and Exchange of the Global Note. The Global Note may
not be transferred as a whole except by the Depositary to a nominee of the

nominee of the Depositary, or by the Depositary

                                       24
<PAGE>

or any such nominee to a successor Depositary or a nominee of such successor
Depositary. The Global Note will be exchanged by the Company for Definitive
Notes if (i) the Company delivers to the Trustee written notice from the
Depositary that it is unwilling or unable to continue to act as Depositary or
that it is no longer a clearing agency registered under the Exchange Act and, in
either case, a successor Depositary is not appointed by the Company within 120
days after the date of such notice from the Depositary or (ii) the Company in
its sole discretion determines that the Global Note (in whole but not in part)
should be exchanged for Definitive Notes and delivers a written notice to such
effect to the Trustee. Upon the occurrence of either of the preceding events in
clause (i) or (ii) above, Definitive Notes shall be issued in such names as the
Depositary shall instruct the Trustee. The Global Note also may be exchanged or
replaced, in whole or in part, as provided in Sections 2.7 and 2.10 hereof.
Every Note authenticated and delivered in exchange for, or in lieu of, the
Global Note or any portion thereof, pursuant to this Section 2.6 or Section 2.7
or 2.10 hereof, that is not a Definitive Note shall be authenticated and
delivered in the form of, and shall be, the Global Note. The Global Note may not
be exchanged for another Note other than as provided in this Section 2.6(a);
however, beneficial interests in the Global Note may be transferred and
exchanged as provided in Section 2.6(b) or (c) hereof.

               (b) Transfer and Exchange of Beneficial Interests in the Global
Note. The transfer and exchange of beneficial interests in the Global Note shall
be effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Global Note
shall be subject to restrictions on transfer comparable to those set forth
herein to the extent required by the Securities Act. Transfers of beneficial
interests in the Global Note also shall require compliance with either clause
(i) or (ii) below, as applicable, as well as one or more of the other following
clauses, as applicable:

                      (i) Transfer of Beneficial Interests in the Global Note.
               Beneficial interests in the Global Note may be transferred to
               Persons who take delivery thereof in the form of a beneficial
               interest in the Global Note. No written orders or instructions
               shall be required to be delivered to the Registrar to effect the
               transfers described in this Section 2.6(b)(i).

                      (ii) All Other Transfers and Exchanges of Beneficial
               Interests in the Global Note. In connection with all transfers
               and exchanges of beneficial interests that are not subject to
               Section 2.6(b)(i) above, the transferor of such beneficial
               interest must deliver to the Registrar either (A) (1) a written
               order from a Participant or an Indirect Participant given to the
               Depositary in accordance with the Applicable Procedures causing
               to be credited a beneficial interest in the Global Note in an
               amount equal to the beneficial interest to be transferred or
               exchanged and (2) instructions given in accordance with the
               Applicable Procedures containing information regarding the
               Participant account to be credited with such increase or (B) (1)
               a written order from a Participant or an Indirect Participant
               given to the Depositary in accordance with the Applicable
               Procedures causing to be issued a Definitive Note in an amount
               equal to the beneficial interest to be transferred or exchanged
               and (2) instructions given by the participant to the Registrar
               containing information regarding the Person in whose name such
               Definitive Note shall be registered to effect the transfer or
               exchange referred to in clause (1) above. Upon satisfaction of
               all of the requirements for

                                       25
<PAGE>

               transfer or exchange of beneficial interests in the Global Note
               contained in this Indenture and the Notes or otherwise applicable
               under the Securities Act, the Trustee shall adjust the principal
               amount of the Global Note pursuant to Section 2.6(g) hereof.

               (c) Transfer or Exchange of Beneficial Interests for Definitive
Notes. If any holder of a beneficial interest in the Global Note proposes to
exchange such beneficial interest for a Definitive Note or to transfer such
beneficial interest to a Person who takes delivery thereof in the form of a
Definitive Note, then, upon satisfaction of the conditions set forth in Section
2.6(b)(ii) hereof, the Trustee shall cause the aggregate principal amount of the
Global Note to be reduced accordingly pursuant to Section 2.6(g) hereof, and the
Company shall execute and the Trustee shall authenticate and deliver to the
Person designated in the instructions a Definitive Note in the appropriate
principal amount. Any Definitive Note issued in exchange for a beneficial
interest pursuant to this Section 2.6(c) shall be registered in such name or
names and in such authorized denomination or denominations as the holder of such
beneficial interest shall instruct the Registrar through instructions from the
Depositary and the Participant or Indirect Participant. The Trustee shall
deliver such Definitive Notes to the Persons in whose names such Notes are so
registered.

               (d) Transfer and Exchange of Definitive Notes for Beneficial
Interests. A Holder of a Definitive Note may exchange such Note for a beneficial
interest in the Global Note or transfer such Definitive Notes to a Person who
takes delivery thereof in the form of a beneficial interest in the Global Note
at any time. Upon receipt of a request for such an exchange or transfer, the
Trustee shall cancel the applicable Definitive Note and increase or cause to be
increased the aggregate principal amount of the Global Note, pursuant to Section
2.6(g).

               (e) Transfer and Exchange of Definitive Notes for Definitive
Notes. Upon request by a Holder of Definitive Notes and such Holder's compliance
with the provisions of this Section 2.6(e), the Registrar shall register the
transfer or exchange of Definitive Notes. Prior to such registration of transfer
or exchange, the requesting Holder shall present or surrender to the Registrar
the Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or
by its attorney, duly authorized in writing. A Holder of Definitive Notes may
transfer such Notes to a Person who takes delivery thereof in the form of a
Definitive Note. Upon receipt of a request to register such a transfer, the
Registrar shall register the Definitive Notes pursuant to the instructions from
the Holder thereof.

               (f) Global Note Legend. The Global Note shall bear a legend in
substantially the following form:

               Unless this certificate is presented by an authorized
               representative of The Depository Trust Company, a New York
               corporation ("DTC"), to Issuer or its 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

                                       26
<PAGE>

               representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
               FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
               as the registered owner hereof, Cede & Co., has an interest
               herein.

               (g) Cancellation or Adjustment of the Global Note. At such time
as all beneficial interests in the Global Note have been exchanged for
Definitive Notes or the Global Note has been redeemed, repurchased or canceled
in whole and not in part, the Global Note shall be returned to or retained and
canceled by the Trustee in accordance with Section 2.11 hereof. At any time
prior to such cancellation, if any beneficial interest in the Global Note is
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in the Global Note or for Definitive Notes, the
aggregate Stated Principal Amount of Notes represented by the Global Note shall
be reduced accordingly (without taking into account any increases due to
deferred interest), in the case of an exchange for Definitive Notes, and an
endorsement shall be made on the Global Note by the Trustee or by the Depositary
in accordance with applicable procedures to reflect such exchange or reduction;
and if the beneficial interest is being exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in the
Global Note, the aggregate Stated Principal Amount of the Global Note (without
taking into account any increases due to deferred interest) shall be increased
accordingly and an endorsement shall be made on the Global Note by the Trustee
or by the Depositary in accordance with applicable procedures to reflect such
increase.

               (h) General Provisions Relating to Transfers and Exchanges.

                      (i) To permit registrations of transfers and exchanges,
               the Company shall execute and the Trustee shall authenticate the
               Global Note and Definitive Notes upon the Company's order or at
               the Registrar's request.

                      (ii) No service charge shall be made to a holder of a
               beneficial interest in the Global Note or to a Holder of a
               Definitive Note for any registration of transfer or exchange, but
               the Company may require payment of a sum sufficient to cover any
               transfer tax or similar governmental charge payable in connection
               therewith (other than any such transfer taxes or similar
               governmental charge payable upon exchange or transfer pursuant to
               Sections 2.10, 3.6, 3.8, 4.13, 4.14 and 9.5 hereof).

                      (iii) The Registrar shall not be required to register the
               transfer of or exchange any Note selected for redemption in whole
               or in part, except the unredeemed portion of any Note being
               redeemed in part.

                      (iv) The Global Note and all Definitive Notes issued upon
               any registration of transfer or exchange of the Global Note or
               Definitive Notes shall be the valid obligations of the Company,
               evidencing the same debt, and entitled to the same benefits under
               this Indenture, as the Global Note or Definitive Notes
               surrendered upon such registration of transfer or exchange.

                                       27
<PAGE>

                      (v) The Company shall not be required (A) to issue, to
               register the transfer of or to exchange any Notes during a period
               beginning at the opening of business 15 days before the day of
               any selection of Notes for redemption under Section 3.2 hereof
               and ending at the close of business on the day of selection, (B)
               to register the transfer of or to exchange any Note so selected
               for redemption in whole or in part, except the unredeemed portion
               of any Note being redeemed in part or (C) to register the
               transfer of or to exchange a Note between a Record Date and the
               next succeeding interest payment date.

                      (vi) Prior to due presentment for the registration of a
               transfer of any Note, the Trustee, any Agent and the Company may
               deem and treat the Person in whose name any Note is registered as
               the absolute owner of such Note for the purpose of receiving
               payment of principal of and interest on such Notes and for all
               other purposes, and none of the Trustee, any Agent or the Company
               shall be affected by notice to the contrary.

                      (vii) The Trustee shall authenticate the Global Note and
               Definitive Notes in accordance with the provisions of Section 2.2
               hereof.

                      (viii) All certifications, certificates and Opinions of
               Counsel required to be submitted to the Registrar pursuant to
               this Section 2.6 to effect a registration of transfer or exchange
               may be submitted by facsimile.

                      (ix) Each Holder of a Note agrees to indemnify the Company
               and the Trustee to their reasonable satisfaction against any
               liability that may result from the transfer, exchange or
               assignment of such Holder's Note in violation of any provision of
               this Indenture or applicable United States Federal or state
               securities law.

                      (x) The Trustee shall have no obligation or duty to
               monitor, determine or inquire as to compliance with any
               restrictions on transfer imposed under this Indenture or under
               applicable law with respect to any transfer of any interest in
               any Note (including any transfers between or among Depositary
               participants or beneficial owners of interest in the Global Note)
               other than to require delivery of such certificates and other
               documentation or evidence as are expressly required by, and to do
               so if and when expressly required by the terms of, this
               Indenture, and to examine the same to determine substantial
               compliance as to form with the express requirements hereof.

               Section 2.7 Replacement Notes. If any mutilated Note is
surrendered to the Trustee or the Company and the Trustee receives evidence to
its reasonable satisfaction of the destruction, loss or theft of any Note, the
Company shall issue and the Trustee, upon receipt of an Authentication Order,
shall authenticate a replacement Note if the Trustee's requirements are met. An
indemnity bond must be supplied by the Holder that is sufficient in the
reasonable judgment of the Trustee and the Company to protect the Company, the
Trustee, any Agent and any authenticating agent from any loss that any of them
may suffer if a Note is replaced. The Company may charge for its expenses in
replacing a Note.

                                       28
<PAGE>

               Every replacement Note is an additional obligation of the Company
and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

               Section 2.8 Outstanding Notes. The Notes outstanding at any time
are all the Notes authenticated by the Trustee except for those canceled by it,
those delivered to it for cancellation, those reductions in the interest in the
Global Note effected by the Trustee in accordance with the provisions hereof,
and those described in this Section 2.8 as not outstanding. Except as set forth
in Section 2.9 hereof, a Note does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Note.

               If a Note is replaced pursuant to Section 2.7 hereof, it ceases
to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

               If the aggregate principal amount of any Note (taking into
account any increases in principal due to deferred interest) is considered paid
under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

               If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any of the foregoing) holds, by no later than 12:00 noon Eastern
Time on a redemption date or maturity date, money sufficient to pay Notes
payable on that date, then on and after that date such Notes shall be deemed to
be no longer outstanding and shall cease to accrue interest.

               Section 2.9 Treasury Notes. In determining whether the Holders of
the required principal amount of Notes have concurred in any direction, waiver
or consent, Notes owned by the Company, or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company, shall be considered as though not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee actually knows are so owned shall be so disregarded.

               Section 2.10 Temporary Notes. Until certificates representing
Notes are ready for delivery, the Company may prepare and the Trustee, upon
receipt of an Authentication Order, shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of certificated Notes but may
have variations that the Company considers appropriate for temporary Notes and
as shall be reasonably acceptable to the Trustee. Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate Definitive Notes in
exchange for temporary Notes.

               Holders of temporary Notes shall be entitled to all of the
benefits of this Indenture.

               Section 2.11 Cancellation. The Company at any time may deliver
Notes to the Trustee for cancellation. The Registrar and Paying Agent shall
forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel all
Notes surrendered for registration of transfer, exchange, payment, replacement
or cancellation and shall dispose of canceled Notes in accordance with its

                                       29
<PAGE>

procedures for the disposition of canceled securities in effect as of the date
of such disposition (subject to the record retention requirement of the Exchange
Act). Certification of the disposition of all canceled Notes shall be delivered
to the Company. The Company may not issue new Notes to replace Notes that they
have paid or that have been delivered to the Trustee for cancellation.

               Section 2.12  Payment of Interest; Defaulted Interest.

               (a) Each of the Notes shall bear interest at 12% per annum
from July 1, 2002 or from the most recent date to which interest has been paid
or duly provided for in accordance with Section 4.1 hereof until the principal
amount thereof is paid. Interest shall be paid to the Person in whose name the
Note is registered as provided in the Notes.

               (b) If the Company defaults in a payment of interest on the Notes
when due, the Company shall pay the defaulted interest in any lawful manner
plus, to the extent lawful, interest payable on the defaulted interest, to the
Persons who are Holders on a subsequent special record date or, in the case of
the payment of non-cash defaulted interest, to the Persons who are Holders on
the date of such payment, in each case at the rate provided in the Notes and in
Section 4.1 hereof. 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. The Company shall fix or cause to be fixed each such
special record date and payment date; provided, that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such cash
interest to be paid.

               Section 2.13 CUSIP Numbers. The Company in issuing the Notes may
use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, that any such notice may state that no representation is made as to
the correctness of such numbers either as printed on the Notes or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company shall
promptly notify the Trustee of any change in the "CUSIP" numbers.

                      ARTICLE 3. REDEMPTION AND PREPAYMENT

               Section 3.1 Notices to Trustee. If the Company elects to redeem
the Notes pursuant to the optional redemption provisions of Section 3.7 hereof,
or is required to redeem the Notes pursuant to the mandatory redemption
provisions of Section 3.8, it shall furnish to the Trustee, at least 20 days but
not more than 60 days before a redemption date (unless the Trustee agrees to a
shorter notice period), an Officers' Certificate setting forth (i) the
redemption date, (ii) the principal amount of Notes to be redeemed, (iii) the
redemption price and (iv) a revised Schedule A as to (x) the aggregate amount of
deferred interest scheduled to be added to principal on all of the Notes on each
Interest Payment Date, and (y) the aggregate amount of interest scheduled to be
paid in cash together with the principal amount of the Notes at maturity, all

                                       30
<PAGE>

based on the same assumptions as those set forth in Schedule A but taking into
account the principal amount of the Notes to be so redeemed as well as any prior
redemptions or other prepayments of principal of the Notes.

               Section 3.2 Selection of Notes to Be Redeemed. If less than all
of the Notes are to be redeemed at any time, the Trustee shall select the Notes
to be redeemed among the Holders in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed in
the United States, or, if the Notes are not listed, on a pro rata basis, or, to
the extent that the Trustee shall have determined that selection on a pro rata
basis is not feasible, by lot or in accordance with any other method the Trustee
considers fair and appropriate. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 15 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

               The Trustee shall promptly notify the Company in writing of the
Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount outstanding to be redeemed. If fewer than all
Notes are to be redeemed at any time, Notes and portions of Notes selected shall
be in integral multiples of $1.00; except that if all of the Notes of a Holder
are to be redeemed, the entire outstanding amount of the Notes held by such
Holder, even if not a multiple of $1.00, shall be redeemed. Except as provided
in the preceding sentence, provisions of this Indenture that apply to Notes
called for redemption also apply to portions of Notes called for redemption.

               Section 3.3 Notice of Redemption. At least 15 days but not more
than 60 days before a redemption date, the Company shall mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address.

               The notice shall identify the Notes to be redeemed, contain a
copy of the revised Schedule A furnished under Section 3.1 in connection with
such redemption, and shall state:

               (a) the redemption date;

               (b) the redemption price;

               (c) if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption date
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original Note;

               (d) the name and address of the Paying Agent;

               (e) that Notes called for redemption must be surrendered to the
Paying Agent to collect the redemption price;

               (f) that, unless the Company defaults in making such redemption
payment, interest on the portion of such Notes called for redemption ceases to
accrue on and after the redemption date;

                                       31
<PAGE>

               (g) the paragraph of the Notes or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

               (h) that no representation is made as to the correctness or
accuracy of the CUSIP number, if any, listed in such notice or printed on the
Notes.

               At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

               Section 3.4 Effect of Notice of Redemption. Once notice of
redemption is mailed in accordance with Section 3.3 hereof, Notes called for
redemption become irrevocably due and payable on the redemption date at the
redemption price. A notice of redemption may not be conditional.

               Section 3.5 Deposit of Redemption Price. Prior to the redemption
date, the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay in cash the redemption price of and accrued interest in cash
on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall
promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest on, all Notes to be redeemed.

               If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after a Cash Record Date but on or prior to the related Interest Payment
Date, then any accrued and unpaid cash interest thereon shall be paid to the
Person in whose name such Note was registered at the close of business on such
Cash Record Date. If any Note called for redemption shall not be so paid upon
surrender for redemption because of the failure of the Company to comply with
the preceding paragraph, interest shall be paid on the unpaid principal, from
the redemption date until such principal is paid, and to the extent lawful on
any interest not paid on such unpaid principal, in each case at the rate
provided in the Notes and in Section 4.1 hereof.

               Section 3.6 Notes Redeemed in Part. Upon surrender of a Note that
is redeemed in part, the Company shall issue and the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in aggregate
Stated Principal Amount (without taking into account any increases due to
deferred interest) to the unredeemed portion of the Note surrendered. No Notes
of $1.00 or less shall be redeemed in part.

               Section 3.7 Optional Redemption. The Company may redeem all or a
part of the Notes upon not less than 30 nor more than 60 days' notice, at the
principal amount outstanding thereof plus accrued interest thereon that has not
been paid or duly provided for, to the applicable redemption date (subject, in
the case of a redemption on or after a Cash Record Date but on or prior to the
related Interest Payment Date, to the right of Holders of record on such Cash
Record Date to receive any cash interest due on the related Interest Payment
Date in

                                       32
<PAGE>

accordance with Section 3.5). If less than all of the Notes are to be redeemed
at any time of redemption, the provisions of this Indenture relating to the
redemption of the Notes shall relate to the portion of the aggregate principal
amount of the Notes which has been or is to be redeemed.

               Section 3.8 Mandatory Redemption. At any time the sum (the
"AGGREGATE PROCEEDS") of (x) the aggregate amount of all Remaining Capital
Raising Proceeds and (y) the aggregate amount of all Remaining Asset Sale
Proceeds exceeds $5 million (a "MANDATORY REDEMPTION TRIGGERING EVENT"), the
Company shall make a mandatory redemption of Senior Notes to the extent required
under the Senior Notes Indenture; provided, however, that if any such Aggregate
Proceeds remain after application to any such redemption of Senior Notes, the
Company shall, within 60 days of such Mandatory Redemption Triggering Event,
redeem the maximum principal amount of the Notes that may be redeemed out of any
such remaining Aggregate Proceeds. Such redemption of the Notes shall be made
upon not less than 15 nor more than 60 days' notice, at the principal amount
outstanding thereof plus accrued interest thereon that has not been paid or duly
provided for, to the applicable redemption date (subject, in the case of a
redemption on or after a Cash Record Date but on or prior to the related
Interest Payment Date, to the right of Holders of record on such Cash Record
Date to receive any cash interest due on the related Interest Payment Date in
accordance with Section 3.5). Pending the final application of any Remaining
Capital Raising Proceeds or Remaining Asset Sale Proceeds, the Company or the
applicable Subsidiary, as the case may be, may invest such proceeds in Cash
which shall be pledged to the Senior Notes Trustee to the extent required by the
Senior Indenture and, to the extent not so required, shall be pledged to the
Trustee as security for the Holders of the Notes.

               The Company shall not be required to make mandatory redemption
payments or sinking fund payments with respect to the Notes other than as set
forth in this Section 3.8.

                              ARTICLE 4. COVENANTS

               Section 4.1 Payment of Notes The Company shall pay or cause to be
paid the principal of, premium, if any, and interest on the Notes on the dates
and in the manner provided herein and in the Notes. Unless the Company has
elected, in its sole discretion, to pay interest in cash in accordance with the
following sentence, on each Interest Payment Date the outstanding principal
amount of each Note shall be automatically increased by the amount of interest
to be paid on such Interest Payment Date in respect of such Note, and upon any
such automatic increase the Company shall be deemed to have paid and duly
provided for such interest payment on such Interest Payment Date; provided,
however, that if the payment of interest by addition to principal in the manner
provided in this sentence shall for any reason be prohibited by applicable law
on any Interest Payment Date, the Company shall be obligated, instead, to
deliver an additional Note, substantially in the form of Exhibit A hereto, to
each Holder in an aggregate principal amount equal to the interest due on such
Holder's Notes on such Interest Payment Date, and as provided in Section 2.1 no
requirements as to minimum denominations shall apply to any such additional
Notes. The Company may elect to pay interest due on any Interest Payment Date in
cash rather than in kind, provided that the Company has so elected and notified
the Trustee and the Paying Agent at least five (5) Business Days prior to the
Cash Record Date that such payment shall be made in cash, such notice to be
accompanied by a revised Schedule A as to (x) the aggregate amount of deferred
interest scheduled to be added to principal on all of the Notes

                                       33
<PAGE>

on each Interest Payment Date subsequent to the Interest Payment Date on which
the Company has elected to pay interest in cash, and (y) the aggregate amount of
interest scheduled to be paid in cash together with the principal amount of the
Notes at maturity, all based on the same assumptions as those set forth in
Schedule A but taking into account such cash payment of interest on such
Interest Payment as well as all prior deferrals of interest, if any. A copy of
such Schedule shall be delivered to any Holder by the Company or the Trustee
promptly upon such Holder's request to such Person. Except as provided in the
second sentence of this Section 4.1, principal, premium, if any, and interest
shall be considered paid on the date due if the Paying Agent, if other than the
Company or one of its Subsidiaries, holds as of 12:00 noon Eastern Time on the
due date money deposited by the Company in immediately available funds and
designated for and sufficient to pay in cash all principal, premium, if any, and
interest then due.

               The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium (if
any) at the rate equal to 14% per annum to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

               Section 4.2 Maintenance of Office or Agency. The Company shall
maintain in the Borough of Manhattan, the City of New York, an office or agency
(which may be an office of the Trustee or an agent of the Trustee, Registrar or
co-registrar) where Notes may be surrendered for registration of transfer or for
exchange and where notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Company shall give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required 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 may also from time to time designate one or more
other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

               The Company hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section
2.3 of this Indenture.

required, shall be held in an account

               Section 4.14 Asset Sales. The Company shall not, and shall not

(i) consideration at the time of the Asset Sale at least equal to the fair
market value of the assets issued, sold or otherwise disposed of or (ii) in the
case of a lease of assets that constitute an Asset Sale, a lease providing for
rents or other consideration which are no less favorable to the Company or the
Subsidiary, as the case may be, than the prevailing market conditions;

               (b) Company's Management Committee adopts a resolution evidencing
its determination that such consideration constitutes such fair market value, or
such lease payments are at prevailing market conditions, as the case may be, as
certified in an Officers' Certificate delivered to the Trustee; and

               (c) at least 75% or, with the approval of the Management
Committee of the Company, 50%, of the consideration therefor received by the
Company or the Subsidiary is in the form of Cash; provided, that:

                      (i) any liabilities (as shown on the Company's or the
               Subsidiary's most recent balance sheet) of the Company or the
               Subsidiary (other than contingent liabilities and liabilities
               that are by their terms subordinated to the Notes) that are
               assumed by the transferee of any of those assets under a
               customary novation agreement that unconditionally releases the
               Company or the Subsidiary, as the case may be, from further
               liability will be deemed to be Cash for purposes of this
               provision; and

                      (ii) any securities, notes or other obligations received
               by the Company or the Subsidiary from the transferee that are
               promptly, but in any event within 30 days of receipt, converted
               by the Company or the Subsidiary into Cash (to the extent of the
               Cash received in that conversion) will be deemed to be Cash for
               purposes of this provision.

               No later than the Business Day following the date of receipt of
any Net Proceeds from an Asset Sale, the Company shall apply 100% of such Net
Proceeds to (i) repay Indebtedness with respect to Permitted Priority Liens
incurred or permitted pursuant to the terms of this Indenture in connection
with, and secured by, the asset so sold and pay down the outstanding balance, if
any, under the Liquidity Facility (or such lesser amount of the outstanding
balance of the Liquidity Facility as approved by at least a majority in
outstanding principal amount of the then outstanding Notes) and to permanently
reduce the loan commitments thereunder by the amount so prepaid. The Company
shall use 50% of any remaining Net Proceeds from any Asset Sale after
application pursuant to the prior sentence (or such lesser amount of Net
Proceeds as is approved by at least a majority in outstanding principal amount
of the then outstanding Notes) as follows: (x) up to $20 million of such amount
may be deposited into the Senior Notes Escrow Account to the extent required by
the Senior Notes

                                       43
<PAGE>

Indenture and, to the extent not so required, into the Escrow Account; and (y)
to the extent not deposited into the Senior Notes Escrow Account or the Escrow
Account, the Company shall use such amount (the "REMAINING ASSET SALE PROCEEDS")
to the extent required by the Senior Notes Indenture to redeem the maximum
principal amount of the Senior Notes that may be redeemed out of the Remaining
Asset Sale Proceeds in accordance with the Senior Notes Indenture and, if any of
such Remaining Asset Sale Proceeds remain after application to any such
redemption of Senior Notes, the Company shall use such remaining amount to
redeem the maximum principal amount of the Notes that may be redeemed out of
such moneys in accordance with Section 3.8.

               Pending the final applications of any Net Proceeds from Asset
Sales governed by the preceding paragraph, the Company or the applicable
Subsidiary may invest such Net Proceeds in Cash which (to the extent required by
the Senior Notes Indenture) shall be held in an account in which the Senior
Notes Trustee shall have a first priority perfected security interest, subject
to Permitted Priority Liens, for the benefit of the Holders of Senior Notes and,
subject to the terms of the Senior Notes Intercreditor Agreement, the Notes and,
to the extent not so required, shall be held in an account in which the Trustee
shall have a first priority perfected security interest, subject to Permitted
Priority Liens, for the benefit of the Holders of Notes.

               law) resulting from or otherwise associated with the events
               listed in subclauses (A) through (C) of this paragraph;

                      (vi) as used in this Section 6.1(f), the term "accumulated
               funding deficiency" has the meaning specified in Section 412 of
               the Internal Revenue Code, and the terms "actuarial present
               value" and "benefit liabilities" have the meanings specified in
               Section 4001 of ERISA; or

               (g) there shall be instituted against the Company, or any of its
Subsidiaries, any proceeding for which forfeiture (to the extent not paid or
covered by insurance or the third party indemnity of a solvent indemnitor) of
any property equal to or greater than $5.0 million is a potential penalty and
such proceeding shall not have been vacated or discharged within thirty (30)
days of its institution.

               Section 6.2 Acceleration. Upon (i) the occurrence of any Event of
Default described in clause (d) above or upon any acceleration of the
outstanding principal amount of any Senior Note or of any outstanding principal
amount owing under the Liquidity Facility, the Notes, and each of them, with
accrued interest thereon, and all other amounts owing under this Indenture and
the Notes shall automatically become due and payable in cash, and (ii) upon the
occurrence and continuance of any other Event of Default, the Trustee, or the
Holders of at least a majority in outstanding principal amount of the then
outstanding Notes may, by notice to the Company, declare the Notes, with accrued
interest thereon, and all other amounts owing under this Indenture and the Notes
to be due and payable forthwith, whereupon the same shall immediately become due
and payable in cash. Except as expressly provided above in this Section 6.2,
presentment, demand, protest and all other notices of any kind are hereby
expressly

                                       53
<PAGE>

waived. The Holders of a majority in outstanding principal amount of the then
outstanding Notes, by written notice to the Trustee, may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal or interest on the Notes that has become due
solely because of the acceleration) have been cured or waived. The foregoing
notwithstanding, if an automatic acceleration of payment of the Notes occurs due
solely to any acceleration of the outstanding principal amount owing under the
Liquidity Facility or any Senior Note and the principal amount owing under the
Liquidity Facility or the Senior Note, as the case may be, Indenture is
subsequently de-accelerated, payment of the Notes shall thereupon also be
automatically de-accelerated (without need for any action on the part of any of
the Holders) unless, prior to any such de-acceleration of principal under the
Liquidity Facility or such Senior Note, as the case may be, the Notes, and all
other amounts owing under this Indenture and the Notes, shall otherwise have
become or been declared due and payable. Any payments in cash received by any
Holder in accordance with the Liquidity Facility Intercreditor Agreement or the
Senior Notes Intercreditor Agreement prior to the date such de-acceleration
occurs may be retained by such Holder.

               Section 6.3 Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal, premium, if any, and interest with respect to, the Notes or to
enforce the performance of any provision of the Notes or this Indenture. The
Trustee may also pursue any remedy available to the Holders of the Notes or the
Trustee, whether hereunder or under the Notes, any of the other Collateral
Documents, the Liquidity Facility Intercreditor Agreement or the Senior Notes
Intercreditor Agreement, or otherwise available to any Holders or the Trustee at
law or equity.

               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 of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

               Section 6.4 Waiver of Past Defaults. Holders of not less than a
majority in outstanding principal amount of then outstanding Notes, by notice to
the Trustee, may on behalf of the Holders of all of the Notes waive an existing
Default or Event of Default and its consequences hereunder, except a continuing
Default or Event of Default in the payment of the principal of, or interest on,
the Notes (including in connection with an offer to purchase) (provided,
however, that the Holders of a majority in outstanding principal amount of then
outstanding Notes may rescind an acceleration and its consequences, including
any related payment default that resulted from such acceleration). Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

               Section 6.5 Control by Majority. Holders of a majority in
outstanding principal amount of then outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it.
However, the Trustee may refuse to follow any direction that conflicts

                                       54
<PAGE>

with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes or that may involve the Trustee in
personal liability. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest.

               Section 6.6 Limitation on Suits. Subject to the restrictions
contained in the Liquidity Facility Intercreditor Agreement and the Senior Notes
Intercreditor Agreement, a Holder of a Note may pursue a remedy with respect to
an Event of Default under this Indenture or any Note only if:

               (a) the Holder of a Note gives to a Responsible Officer of the
Trustee written notice of a continuing Event of Default;

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

               (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

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

               (e) during such 60-day period the Holders of a majority in
outstanding principal amount of then outstanding Notes do not give the Trustee a
direction inconsistent with the request.

               A Holder of a Note may not use this Indenture to prejudice the
rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note other than as expressly provided in this Indenture.

               Section 6.7 Rights of Holders of Notes to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
of a Note to receive payment of principal, premium, if any, or interest with
respect to, the Note, on or after the respective due dates expressed in the Note
(including in connection with an offer to purchase), 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 such Holder.

               Section 6.8 Collection Suit by Trustee. If an Event of Default
specified in Section 6.1(a) 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 for the whole amount of principal remaining unpaid of, interest
remaining unpaid on the Notes and interest on overdue principal and premium, if
any, and, to the extent lawful, interest, and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

               Section 6.9 Trustee May File Proofs of Claim. The Trustee is
authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in

                                       55
<PAGE>

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 of the Notes 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 7.7 hereof. 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 7.7
hereof 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 that
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, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

               Section 6.10 Priorities. If the Trustee collects any money
pursuant to this Article 6, after application to any amounts contemplated by
clauses (b) and (c) of the second paragraph of Section 10.15, the Trustee shall
pay out such money in the following order:

               First: to the Trustee, its agents and attorneys for amounts due
        under Section 7.7 hereof, 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 of Notes for amounts due and unpaid on the
        Notes for principal, premium, if any, and interest ratably, without
        preference or priority of any kind, according to the amounts due and
        payable on the Notes for principal, premium, if any, and interest,
        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 of
Notes pursuant to this Section 6.10.

               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, 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 6.11 does not apply
to a suit by the Trustee, a suit by a Holder of a Note

                                       56
<PAGE>

pursuant to Section 6.7 hereof, or a suit by Holders of more than ten percent in
aggregate amount of the then outstanding Notes.

               Section 6.12 Restoration of Rights and Remedies. If the Trustee
or any Holder has instituted a proceeding to enforce any right or remedy under
this Indenture, any of the Notes, the Liquidity Facility Intercreditor
Agreement, the Senior Notes Intercreditor Agreement or any other Collateral
Document 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, 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 has been
instituted.

                               ARTICLE 7. TRUSTEE

               Section 7.1 Duties of Trustee.

               (a) If 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 the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement and the other Collateral Documents, and use the same
degree of care and skill in its exercise, as a prudent person would exercise or
use under the circumstances in the conduct of such person's own affairs.

               (b) Except during the continuance of an Event of Default:

                      (i) the duties of the Trustee shall be determined solely
               by the express provisions of this Indenture, the Liquidity
               Facility Intercreditor Agreement, the Senior Notes Intercreditor
               Agreement and the other Collateral Documents and the Trustee need
               perform only those duties that are specifically set forth in this
               Indenture, the Liquidity Facility Intercreditor Agreement, the
               Senior Notes Intercreditor Agreement, the other Collateral
               Documents 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, the Liquidity Facility
               Intercreditor Agreement, the Senior Notes Intercreditor Agreement
               and the other Collateral Documents. However, the Trustee shall
               examine the certificates and opinions to determine whether or not
               they conform to the requirements of this Indenture, the Liquidity
               Facility Intercreditor Agreement, the Senior Notes Intercreditor
               Agreement and the other Collateral Documents.

               (c) Notwithstanding any contrary provision of any document or
instrument, the Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                                       57
<PAGE>

                      (i) this paragraph does not limit the effect of clause (b)
               of this Section 7.1;

                      (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 6.5 hereof.

               (d) Whether or not therein expressly so provided, every provision
of this Indenture, the Liquidity Facility Intercreditor Agreement, the Senior
Notes Intercreditor Agreement and the other Collateral Documents that in any way
relates to the Trustee is subject to clauses (a), (b) and (c) of this Section
7.1.

               (e) No provision of this Indenture, the Liquidity Facility
Intercreditor Agreement, the Senior Notes Intercreditor Agreement or any other
Collateral Document shall require the Trustee to expend or risk its own funds or
incur any liability.

               (f) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

               Section 7.2 Certain Rights of Trustee.

               (a) The Trustee may conclusively rely upon any document believed
by it to be genuine and to have been signed or presented by the proper Person.
The Trustee need not investigate any fact or matter stated in the document.

               (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may
consult with counsel and the advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

               (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent appointed
with due care.

               (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith, without negligence or willful misconduct, that it
believes to be authorized or within the rights or powers conferred upon it by
this Indenture, the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement or any other Collateral Document.

               (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

                                       58
<PAGE>

               (f) 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 unless such Holders shall have offered to the Trustee
security or indemnity reasonably satisfactory to it against the costs, expenses
and liabilities that might be incurred by it in compliance with such request or
direction.

               (g) 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,
debenture, note, other evidence of Indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit and shall incur no liability or
additional liability of any kind by reason of such inquiry or investigation.

               (h) The Trustee shall not be deemed to have notice of any Default
or Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of such event is sent to the Trustee
in accordance with Section 13.2 hereof, and such notice references the Notes;
and

               (i) 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 co-trustee
employed to act hereunder.

               Section 7.3 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may become a creditor of, or otherwise deal with, the Company, or any Affiliate
of the Company with the same rights it would have if it were not Trustee.
However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

               Section 7.4 Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement, the other Collateral Documents or the Notes, it shall
not be accountable for the Company's use of the proceeds from the Notes or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture, the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement or the other Collateral Documents, it shall not be
responsible for the use or application of any money received by any Paying Agent
other than the Trustee, and it shall not be responsible for any statement or
recital herein or any statement in the Notes or any other document in connection
with the sale of the Notes or pursuant to this Indenture other than its
certificate of authentication.

               Section 7.5 Notice of Defaults. If a Default or Event of Default
occurs and is continuing and if it is actually known to the Trustee, the Trustee
shall mail to Holders of Notes a notice of the Default or Event of Default
within 90 days after it occurs. Except in the case of a Default or Event of
Default in payment of principal of, or interest on, any Note, the Trustee may

                                       59
<PAGE>

withhold the notice if and so long as a Responsible Officer in good faith
determines that withholding the notice is in the interests of the Holders of the
Notes.

               Section 7.6 Reports by Trustee to Holders of the Notes; Stock
Exchange Listing. Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA Section 313(a) (but if no
event described in TIA Section 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail
all reports as required by TIA Section 313(c).

               A copy of each report at the time of its mailing to the Holders
of Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA Section 313(d).
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange or any delisting thereof.

               Section 7.7 Compensation and Indemnity. The Company shall pay to
the Trustee from time to time such compensation for its acceptance of this
Indenture and services hereunder in accordance with a written schedule provided
by the Trustee to the Company. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

               The Company shall indemnify the Trustee against any and all
losses, liabilities or expenses (including fees of legal counsel to the Trustee)
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture or any Note, the Liquidity Facility
Intercreditor Agreement, the Senior Notes Intercreditor Agreement or any other
Collateral Document against the Company or any other party thereto (including
this Section 7.7) and defending itself against any claim (whether asserted by
the Company or any Holder or any other Person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or willful misconduct. The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder.
The Company shall defend the claim and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel and the Company shall pay the
reasonable and duly documented fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

               The obligations of the Company under this Section 7.7 shall
survive the satisfaction and discharge of this Indenture.

               To secure the Company's payment obligations in this Section 7.7,
the Trustee shall have a Lien prior to the Notes on all money or property held
or collected by the Trustee,

                                       60
<PAGE>

except that held in trust to pay principal and interest on particular Notes.
Such Lien shall survive the satisfaction and discharge of this Indenture.

               When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.1(d) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

               The Trustee shall comply with the provisions of TIA Section
313(b)(2) to the extent applicable.

               Section 7.8 Replacement of Trustee. A resignation or removal of
the Trustee and appointment of a successor Trustee shall become effective only
upon the successor Trustee's acceptance of appointment as provided in this
Section 7.8.

               The Trustee may resign in writing at any time and be discharged
from the trust hereby created by so notifying the Company. The Holders of a
majority in outstanding principal amount of then outstanding Notes may remove
the Trustee by so notifying the Trustee and the Company in writing. The Company
may remove the Trustee if:

               (a) the Trustee fails to comply with Section 7.10 hereof;

               (b) the Trustee is adjudged a bankrupt or an insolvent or an
order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

               (c) a custodian or public officer takes charge of the Trustee or
its property; or

               (d) the Trustee becomes incapable of acting.

               If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee; provided, however, that if a Default or Event of Default has
occurred and is continuing, or if any Holder shall have given notice to the
Trustee under Section 6.6, the Holders of a majority in outstanding principal
amount of then outstanding Notes may appoint a successor Trustee or appoint a
successor Trustee to replace any successor Trustee appointed by the Company.
Within one year after the successor Trustee takes office, the Holders of a
majority in outstanding principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

               If a successor Trustee does not take office within 30 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Company,
or the Holders of at least ten percent (10%) in outstanding principal amount of
then outstanding Notes may petition any court of competent jurisdiction at the
expense of the Company for the appointment of a successor Trustee.

               If the Trustee, after written request by any Holder who has been

Trustee hereunder, under the Liquidity Facility Intercreditor Agreement, the
Senior Notes Intercreditor Agreement, or under the other Collateral Documents)
against any of the assets of the Company held by the Trustee; provided, however,
that if the Trustee is or becomes a lender of any other Indebtedness permitted
hereunder to be pari passu with the Notes, then such waiver shall not apply to
the extent of such Indebtedness.

Anything herein contained to the contrary notwithstanding, (a) the Company shall
remain liable under each of the Collateral Documents to which it is a party to
the extent set forth therein to perform all of its duties and obligations

obligations under each of the Collateral Documents to which it is a party and
(c) neither the Holders nor the Trustee shall have any obligation or liability

thereon or as to preservation of rights against prior parties or any other
rights pertaining thereto and the Trustee shall not be responsible for filing
any financing or continuation statements or recording any documents or
instruments in any public office at any time or times or otherwise perfecting or
maintaining the perfection of any security interest in the Collateral. The
Trustee shall be deemed to have exercised reasonable care in the custody of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which it accords its own property and shall not be
liable or responsible for any loss or diminution in the value of any of the
Collateral, by reason of the act or omission of any carrier, forwarding agency
or other agent or bailee selected by the Trustee in good faith.

               (b) Subject to Section 7.1, the Trustee shall not be responsible
for the existence, genuineness or value of any of the Collateral or for the
validity, perfection, priority or enforceability of the Liens in any of the
Collateral, whether impaired by operation of law or by reason of any action or
omission to act on its part hereunder, except to the extent such action or
omission constitutes negligence, or willful misconduct on the part of the
Trustee, for the validity or sufficiency of the Collateral or any agreement or
assignment contained therein, for the validity of the title of the Company to
the Collateral, for insuring the Collateral or for the payment of taxes,
charges, assessments or Liens upon the Collateral or otherwise as to the
maintenance of the Collateral.

               Section 7.15 Appointment of Co-Trustee. It is the purpose of this
Indenture that there shall be no violation of any law of any jurisdiction
denying or restricting the right of banking corporations or associations to
transact business as Trustee in such jurisdiction. It is recognized that in case
of litigation under this Indenture, and in particular in case of the enforcement
thereof on default, or in the case the Trustee deems that by reason of any
present or future law of any jurisdiction it may not exercise any of the powers,
rights or remedies granted to the Trustee herein or in the Liquidity Facility
Intercreditor Agreement, the Senior Notes

Intercreditor Agreement or any of the other Collateral Documents or hold title
to the properties, in trust, as herein granted or take any action which may be
desirable or necessary in connection therewith, it may be necessary that the
Trustee appoint an individual or institution as a separate or co-trustee. The
following provisions of this Section are adopted to these ends.

               In the event that the Trustee appoints an additional individual
or institution as a separate or co-trustee, each and every remedy, power, right,
claim, demand, cause of action, immunity, estate, title, interest and lien
expressed or intended by this Indenture or the Liquidity Facility Intercreditor
Agreement or the Senior Notes Intercreditor Agreement or any of the other
Collateral Documents to be exercised by or vested in or conveyed to the Trustee
with respect thereto shall be exercisable by and vest in such separate or
co-trustee but only to the extent necessary to enable such separate or
co-trustee to exercise such powers. rights and remedies, and only to the extent
that the Trustee by the laws of any jurisdiction (including particularly the
State of New York) is incapable of exercising such powers, rights and remedies
and every covenant and obligation necessary to the exercise thereof by such
separate or co-trustee shall run to and be enforceable by either of them.

               Should any instrument in writing from the Company be required by
the separate or co-trustee so appointed by the Trustee for more fully and
certainly vesting in and confirming to him or it such properties, rights,
powers, trusts, duties and obligations, any and all such instruments in writing
shall, on request, be executed, acknowledged and delivered by the Company;
provided, that if a Default or an Event of Default shall have occurred and be
continuing, if the Company does not execute any such instrument within fifteen
(15) days after request therefor, the Trustee shall be empowered as an
attorney-in-fact for the Company to execute any such instrument in the Company's
name and stead. In case any separate or co-trustee or a successor to either
shall die, become incapable of acting, resign or be removed, all the estates,
properties, rights, powers, trusts, duties and obligations of such separate or
co-trustee, so far as permitted by law, shall vest in and be exercised by the
Trustee until the appointment of a new trustee or successor to such separate or
co-trustee.

               Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                      (i) all rights and powers, conferred or imposed upon the
               Trustee shall be conferred or imposed upon and may be exercised
               or performed by such separate trustee or co-trustee; and

                      (ii) No trustee hereunder shall be personally liable by
               reason of any act or omission of any other trustee hereunder.

               Any notice, request or other writing given to the Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Indenture and
the conditions of this Section 7.15.

               Any separate trustee or co-trustee may at any time appoint the
Trustee as its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Indenture, the Notes, the Liquidity Facility Intercreditor Agreement,

                                       64

the Senior Notes Intercreditor Agreement or any of the other Collateral
Documents, on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.

               Section 7.16 No Liability for Clean-up of Hazardous Materials. In
the event that the Trustee is required to acquire title to an asset for any
reason, or take any managerial action of any kind in regard thereto, in order to
carry out any fiduciary or trust obligation for the benefit of another, which in
the Trustee's sole discretion may cause the Trustee to be considered an "owner
or operator" under the provisions of the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA), 42 U.S.C. Section 9601, et seq., or
otherwise cause the Trustee to incur liability under CERCLA or any other
federal, state or local law, the Trustee reserves the right, instead of taking
such action, either to resign as Trustee or to arrange for the transfer of the
title or control of the asset to a court appointed receiver.

               The Trustee shall not be liable to the Company or Holders or any
other person for any environmental claims or contribution actions under any
federal, state or local law, rule or regulation by reason of the Trustee's
actions and conduct as authorized, empowered and directed hereunder or relating
to the discharge, release or threatened release of hazardous materials into the
environment.

                  ARTICLE 8. DEFEASANCE AND COVENANT DEFEASANCE

               Section 8.1 Option to Effect Legal Defeasance or Covenant
Defeasance. The Company may, at the option of the Management Committee of the
Company evidenced by a resolution set forth in an Officers' Certificate, at any
time, elect to have either Section 8.2 or 8.3 hereof be applied to all
outstanding Notes upon compliance with the conditions set forth below in this
Article 8.

               Section 8.2 Legal Defeasance and Discharge. Upon the Company's
exercise under Section 8.1 hereof of the option applicable to this Section 8.2,
the Company shall, subject to the satisfaction of the conditions set forth in
Section 8.4 hereof, be deemed to have been discharged from its obligations with
respect to all outstanding Notes on the date the conditions set forth below are
satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, 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 8.5 hereof and the
other Sections of this Indenture referred to in clauses (a) and (b) below, and
to have satisfied all its other obligations under the 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: (a) the
rights of Holders of outstanding Notes to receive solely from the trust fund
described in Section 8.4 hereof, and as more fully set forth in such Section,
payments in respect of the principal of, or interest or premium on such Notes
when such payments are due, (b) the Company's obligations with respect to such
Notes under Article 2 and Section 4.2 hereof, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Company's obligations in
connection therewith and (d) this Article 8. Subject to compliance with this
Article 8, the Company may exercise its

                                       65
<PAGE>

option to apply this Section 8.2 notwithstanding the prior exercise of its
option to apply Section 8.3 hereof.

               Section 8.3 Covenant Defeasance. Upon the Company's exercise
under Section 8.1 hereof of the option applicable to this Section 8.3, the
Company shall, subject to the satisfaction of the conditions set forth in
Section 8.4 hereof, be released from its obligations under the covenants
contained in Sections 4.10 through 4.20, and 4.22 through 4.24 hereof with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.4 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 (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.1 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Company's exercise under Section
8.1 hereof of the option applicable to this Section 8.3, subject to the
satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(b),
(c), (e) and (g) shall not constitute Events of Default.

               Section 8.4 Conditions to Legal or Covenant Defeasance. The
following shall be the conditions to the application of either Section 8.2 or
8.3 hereof to the outstanding Notes:

               (a) the Company must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders, cash in United States dollars,
noncallable Government Securities, or a combination thereof, in such amounts as
will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay in cash the principal of, premium (if
any) and interest on the outstanding Notes on the stated maturity or on the
applicable redemption date, as the case may be, and the Company must specify
whether the Notes are being defeased to maturity or to a particular redemption
date;

               (b) in the case of an election under Section 8.2 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that (a) the Company has received from, or
there has been published by, the Internal Revenue Service a ruling or (b) since
the date of this Indenture, there has been a change in the applicable Federal
income tax law, in either case to the effect that, and based thereon such
Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will
not recognize income, gain or loss for Federal income tax purposes as a result
of such Legal Defeasance and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred;

               (c) in the case of an election under Section 8.3 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee

                                       66
<PAGE>

confirming that the Holders of the outstanding Notes will not recognize income,
gain or loss for Federal income tax purposes as a result of such Covenant
Defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred;

               (d) no Default or Event of Default shall have occurred and be
continuing either (a) on the date of such deposit (other than a Default or Event
of Default resulting from the borrowing of funds to be applied to such deposit)
or (b) insofar as Section 6.1(d) hereof is concerned, at any time in the period
ending on the 91st day after the date of deposit;

               (e) such Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute a default under, any material
agreement or instrument (except with respect to the borrowing of funds described
in clause (d) above) to which the Company or any of its Subsidiaries is a party
or by which the Company or any of its Subsidiaries are bound;

               (f) the Company shall deliver to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company or the Officers
signatory thereto with the intent of preferring the Holders of Notes over other
creditors of the Company or with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others;

               (g) the Company shall deliver to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been
complied with; and

               (h) the Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that:

                      (i) the trust funds will not be subject to any rights of
               holders of Indebtedness of the Company other than the Notes, and

                      (ii) assuming no intervening bankruptcy by the Company
               between the date of deposit and the 91st day following the
               deposit and assuming that no Holder is an "insider" of the
               Company under applicable Bankruptcy law, after the 91st day
               following the deposit, the trust funds will not be subject to the
               effect of any applicable bankruptcy, insolvency, reorganization
               or similar laws affecting creditors' rights generally.

               Section 8.5 Deposited Money and Government Securities to Be Held
in Trust; Other Miscellaneous Provisions. Subject to Section 8.6 hereof, all
money and non-callable Government Securities (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 8.5, the "Trustee") pursuant to Section 8.4 hereof 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, premium
(if any) and interest, but such money need not be segregated from other funds
except to the extent required by law.

                                       67
<PAGE>

               The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.4 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.

               Section 8.6 Repayment to the 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 on any Note and
remaining unclaimed for two years after such principal, and premium, if any, or
interest has become due and payable shall be paid to the Company on its request
or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Note shall thereafter 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, may 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 8.7 Reinstatement. If the Trustee or Paying Agent is
unable to apply any United States dollars or non-callable Government Securities
in accordance with Section 8.2 or 8.3 hereof, 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 Company's
obligations under this Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.2 or 8.3 hereof, as the case may be; provided,
however, that, if the Company makes any cash payment of principal of, or
interest on, any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money held by the Trustee or Paying Agent.

                   ARTICLE 9. AMENDMENT, SUPPLEMENT AND WAIVER

               Section 9.1 Without Consent of Holders of Notes. Notwithstanding

               (b) to provide for uncertificated Notes in addition to or in
place of certificated Notes;

               (c) to make any change that would provide any additional rights
or benefits to the Holders of the Notes or that does not adversely affect the
legal rights hereunder of any Holder of a Note;

<PAGE>

               (d) to enter into additional or supplemental Collateral
Documents pursuant to Section 10.16 hereof or additional intercreditor or
subordination agreements pursuant to Section 4.12(i); and

               (e) to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA;

provided, however, that in the case of a change pursuant to clause (a) or (e)
above, the Company shall deliver to the Trustee an Opinion of Counsel stating
that the change does not adversely affect the right of any Holder.

               Upon the request of the Company accompanied by a resolution of
the Company's Management Committee authorizing the execution of any such amended
or supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.2(b) hereof, the Trustee shall join with the Company in
the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

               Section 9.2 With Consent of Holders of Notes. Except as provided
below in this Section 9.2, the Company and the Trustee may amend or supplement
this Indenture, the Notes, the Liquidity Facility Intercreditor Agreement, the
Senior Notes Intercreditor Agreement, or the other Collateral Documents with the
consent of the Holders of at least a majority in outstanding principal amount of
the then outstanding Notes voting as a single class (including, without
limitation, consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes), and, subject to Sections 6.4 and 6.7
hereof, any existing Default or Event of Default or compliance with any
provision of this Indenture, the Notes, the Liquidity Facility Intercreditor
Agreement, the Senior Notes Intercreditor Agreement, or the other Collateral
Documents may be waived with the consent of the Holders of a majority in
outstanding principal amount of the then outstanding Notes voting as a single

               The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Persons entitled to consent to any indenture
supplemental hereto. If a record date is fixed, the Holders on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided that unless such consent shall have
become effective by virtue of the requisite percentage having been obtained
prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be
cancelled and of no further effect.

               Upon the request of the Company accompanied by a resolution of
its Management Committee authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consents of the Holders of Notes as

amended or supplemental Indenture unless such amended or supplemental Indenture
directly affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

               It shall not be necessary for the consent of the Holders of Notes
under this Section 9.2 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

               After an amendment, supplement or waiver under this Section 9.2
becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amendment or
supplemental Indenture or waiver. Subject to Sections 6.4 and 6.7 hereof, the
Holders of a majority in aggregate outstanding principal amount of the then
outstanding Notes voting as a single class may waive compliance in a particular
instance by the Company with any provision of this Indenture, the other
Collateral Documents, the Liquidity Facility Intercreditor Agreement, the Senior
Notes Intercreditor Agreement, or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.2 may not
(with respect to any Notes held by a non-consenting Holder):

                      (i) reduce the principal amount of Notes whose Holders
               must consent to an amendment, supplement or waiver;

                      (ii) reduce the principal of or change the fixed maturity
               of any Note or alter the provisions with respect to the
               redemption of the Notes (other than provisions relating to
               Sections 4.13 and 4.14 hereof);

                      (iii) reduce the rate of or change the time for payment of
               interest on any Note;

                      (iv) waive a Default or Event of Default in the payment of
               principal of, or interest, on the Notes (except a rescission of
               acceleration of the Notes by the Holders of at least a majority
               in aggregate outstanding principal amount of the Notes and a
               waiver of the payment default that resulted from such
               acceleration);

                      (v) make any Note payable in money other than that stated
               in the Notes;

                      (vi) make any change in the provisions of this Indenture
               relating to waivers of past Defaults or Events of Default or the
               rights of holders of Notes to receive payments of principal of,
               or interest or premium on the Notes;

                      (vii) waive a redemption payment with respect to any Note
               or modify the obligations of the Company to make offers to
               purchase Notes from the proceeds of one or more Asset Sales or
               Capital Raising Events;

                                       70
<PAGE>

                      (viii) release all or substantially all of the Collateral
               from the Lien of this Indenture or the other Collateral Documents
               (except in accordance with the provisions thereof); or

                      (ix) make any change in the preceding amendment and waiver
               provisions.

               Any amendment to, or waiver of, the provisions of any of the
Collateral Documents (other than the Indenture), Section 4.15 hereof or the
security provisions of this Indenture will require the consent of the holders of
not less than a majority in outstanding principal amount of Notes then
outstanding.

               Section 9.3 Compliance with Trust Indenture Act. Every amendment
or supplement to this Indenture, the other Collateral Documents or the Notes
shall be set forth in an amended or supplemental Indenture that complies with
the TIA as then in effect.

               Section 9.4 Revocation and Effect of Consents. Until an
amendment, supplement or waiver becomes effective, a consent to it by a Holder
of a Note is a continuing consent by the Holder of a Note and every subsequent
Holder of a Note or portion of a Note that evidences the same Indebtedness as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of
revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

               Section 9.5 Notation on or Exchange of Notes. The Trustee may
place an appropriate notation about an amendment, supplement or waiver on any
Note thereafter authenticated. The Company in exchange for any Note may issue
and the Trustee shall, upon receipt of an Authentication Order, authenticate a
new Note that reflects the amendment, supplement or waiver.

               Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

               Section 9.6 Trustee to Sign Amendments, Etc. The Trustee may sign
any amended or supplemental indenture, Collateral Document, Liquidity Facility
Intercreditor Agreement, the Senior Notes Intercreditor Agreement, or Note
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplement to the Indenture, the
Liquidity Facility Intercreditor Agreement, the Senior Notes Intercreditor
Agreement, any other Collateral Document or any Note until its Management
Committee approves it. In executing any amendment or supplement to this
Indenture, any other Collateral Document, the Liquidity Facility Intercreditor
Agreement, the Senior Notes Intercreditor Agreement or any Note, the Trustee
shall be entitled to receive and (subject to Section 7.1 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section 13.4
hereof, an Officers' Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted
by this Indenture.

                       ARTICLE 10. COLLATERAL AND SECURITY

               Section 10.1 Security. The due and punctual payment of the
principal of, premium and interest on the Notes when and as the same shall be
due and payable, whether on an interest payment date, at maturity, by
acceleration, repurchase, redemption or otherwise, and interest on the overdue
principal of, premium and interest on the Notes and performance of all other
obligations of the Company to the Holders of Notes or the Trustee under this
Indenture or the Notes, according to the terms hereunder or thereunder, shall be
secured by the Collateral as provided in the Collateral Documents. Each Holder
of Notes, by its acceptance hereof and thereof, consents and agrees to the terms
of the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement and the Collateral Documents (including, without
limitation, the provision providing for foreclosure and release of Collateral as
well as any additional intercreditor arrangements entered into by the Trustee
pursuant to Section 7.12 hereof) as the same may be in effect or may be amended
from time to time in accordance with its terms, and authorizes and directs the
Trustee to enter into the Liquidity Facility Intercreditor Agreement, the Senior
Notes Intercreditor Agreement and the Collateral Documents and to perform its
obligations and exercise its rights thereunder in accordance therewith. The
Company shall deliver to the Trustee copies of all documents executed pursuant
to this Indenture, the Liquidity Facility Intercreditor Agreement, the Senior
Notes Intercreditor Agreement and the other Collateral Documents and shall do or
cause to be done all such acts and things as may be necessary or proper, or as
may be required by the provisions of this Indenture or the other Collateral
Documents to assure and confirm to the Trustee the security interest in the
Collateral contemplated hereby, by the other Collateral Documents, or any part
thereof, as from time to time constituted, so as to render the same available
for the security and benefit of this Indenture and of the Notes secured thereby,
according to the intent and purposes herein and therein expressed. The Company
shall take, any and all actions reasonably required to cause this Indenture and
the other Collateral Documents to create and maintain, as security for the
obligations of the Company hereunder, a valid and enforceable perfected Lien on
the Collateral, subject only to Permitted Priority Liens.

               Section 10.2 Grant of a Security Interest. The Company hereby
grants to the Trustee, for the benefit of the Holders, continuing Liens on all
right, title, and interest of the Company in and to all currently existing and
hereafter acquired or arising Collateral (other than Real Property Collateral)
in order to secure prompt repayment of any and all Obligations and in order to
secure prompt performance by the Company of its covenants and duties under this
Indenture (the "TRUSTEE'S LIENS"). The Trustee's Liens in and to the Collateral
(other than Real Property Collateral) shall attach to all Collateral (other than
Real Property Collateral) without further act on the part of Holders or the
Company. Anything contained in this Indenture or any other Collateral Document
to the contrary notwithstanding, except as permitted by Section 4.14, the
Company shall not have authority, express or implied, to dispose of any item or
portion of the Collateral. The secured claims of the Holders with respect to the
Obligations secured by the Collateral shall be of equal priority, and ratable
according to the respective Obligations due each Holder.

               Section 10.3 Collateral Matters. Subject to Sections 10.11 and
10.12, the Holders hereby irrevocably direct and authorize the Trustee, subject
to the Liquidity Facility Intercreditor Agreement and the Senior Notes
Intercreditor Agreement, to release any Lien on

                                       72
<PAGE>

any Collateral (i) upon payment and satisfaction in full by or on behalf of the
Company of all Obligations in accordance with Article 11; and upon such
termination, Trustee shall deliver to the Company, at the Company's sole cost
and expense, all documents reasonably requested by the Company to terminate this
Indenture and the other Collateral Documents and release the Liens with respect
to the Collateral; (ii) constituting property being sold or disposed of if a
release is required or desirable in connection therewith and if the Company
certifies to the Trustee that the sale or disposition is permitted under Section
4.14 of this Indenture (and, subject to Section 7.1, the Trustee may rely
conclusively on any such certificate, without further inquiry); (iii)
constituting property in which the Company owned no interest at the time the
Lien was granted or at any time thereafter, provided, that such property shall
not have been transferred by the Company other than in accordance with the terms
and provisions of this Indenture and the other Collateral Documents; or (iv)
constituting property leased to the Company under a lease that has expired or is
terminated in a transaction permitted under this Indenture or the other
Collateral Documents. Except as provided above, the Trustee will not execute and
deliver a release of any Lien on any Collateral without the prior written
authorization of (y) if the release is of all or any substantial portion of the
Collateral, all of the Holders, or (z) otherwise, the majority in principal
amount of the then outstanding Notes; provided, however, that (1) the Trustee
shall not be required to execute any document necessary to evidence such release
on terms that, in the Trustee's opinion, would expose the Trustee to liability
or create any obligation on the part of the Trustee or the Holders or entail any
consequence adverse to the Trustee or the Holders other than the release of such
Lien without recourse, representation, or warranty, and (2) such release shall
not in any manner discharge, affect, or impair the Obligations or any Liens
(other than those expressly being released) upon (or obligations of the Company
in respect of) all interests retained by the Company, including, the proceeds of
any sale, all of which shall continue to constitute part of the Collateral. The
Company shall furnish to the Trustee, prior to each proposed release of
Collateral pursuant to the Collateral Documents, all documents required by TIA
Section 314(d).

               Section 10.4 Negotiable Collateral. Subject to the provisions of
the Liquidity Facility Intercreditor Agreement and the Senior Notes
Intercreditor Agreement, in the event that any Collateral, including proceeds,
is evidenced by or consists of Negotiable Collateral, the Company promptly shall
endorse and deliver physical possession of such Negotiable Collateral to the
Senior Notes Trustee to be held for the benefit of the holders of the Senior
Notes and, subject to the terms of the Senior Notes Intercreditor Agreement, the
Holders of the Notes.

               Section 10.5 Collection of Accounts, General Intangibles, and
Negotiable Collateral. Subject to the provisions of the Liquidity Facility
Intercreditor Agreement and the Senior Notes Intercreditor Agreement, at any
time after the occurrence and during the continuance of an Event of Default, the
Trustee or the Trustee's designee may (a) notify customers or Account Debtors of
the Company that the Accounts, General Intangibles, or Negotiable Collateral
have been assigned to the Trustee or that the Trustee for the benefit of the
Holders has a security interest therein and (b) collect the Accounts, General
Intangibles, and Negotiable Collateral directly and charge the collection costs
and expenses to the Company.

               Section 10.6 Power of Attorney. Subject to the provisions of the
Liquidity Facility Intercreditor Agreement and the Senior Notes Intercreditor
Agreement, the Company hereby irrevocably makes, constitutes, and appoints the
Trustee (and any of the Trustee's

                                       73
<PAGE>

officers, employees, or agents designated by the Trustee) as the Company's true
and lawful attorney, with power to (a) if the Company refuses to, or fails
timely to execute and deliver any of the documents described in Section 10.9,
sign the name of the Company on, and file, any of the documents described in
Section 10.9, (b) at any time that an Event of Default has occurred and is
continuing, sign the Company's name on any invoice or bill of lading relating to
any Account, drafts against Account Debtors, schedules and assignments of
Accounts, verifications of Accounts, and notices to Account Debtors, (c) send
requests for verification of Accounts, (d) endorse the Company's name on any
checks, notes, instruments, and other items of payment that may come into the
Trustee's or the Holders' possession, (e) at any time that an Event of Default
has occurred and is continuing, notify the post office authorities to change the
address for delivery of the Company's mail to an address designated by the
Trustee, to receive and open all mail addressed to the Company, and to retain
all mail relating to the Collateral and forward all other mail to the Company,
(f) at any time that an Event of Default has occurred and is continuing, make,
settle, and adjust all claims under the Company's policies of insurance and make
all determinations and decisions with respect to such policies of insurance, and
(g) at any time that an Event of Default has occurred and is continuing, settle
and adjust disputes and claims respecting the Accounts directly with Account
Debtors, for amounts and upon terms that Trustee determines to be reasonable,
and the Trustee may cause to be executed and delivered any documents and
releases that Trustee determines to be necessary. The appointment of the Trustee
as the Company's attorney, and each and every one of the Trustee's rights and
powers, being coupled with an interest, is irrevocable until all of the
Obligations have been fully and finally repaid and performed and this Indenture
has been discharged in accordance with Article 11.

               Section 10.7 Grants, Rights and Remedies. The Liens and security
interests granted by the Company to the Trustee (for its benefit and for the
benefit of the Holders) by and pursuant to Section 10.2 hereof may be
independently granted by the Collateral Documents and by other collateral
documents hereafter entered into. This Indenture and such other Collateral
Documents supplement each other, and the grants, priorities, rights and remedies
of the Trustee and the Holders hereunder and thereunder are cumulative.

               Section 10.8 Survival. To the fullest extent provided under
applicable law, the Liens and security interests granted to the Trustee (for its
benefit and for the benefit of the Holders), the priority of such Liens and
security interests, and other rights and remedies granted to the Trustee and the
Holders pursuant to this Indenture and the other Collateral Documents
(specifically including but not limited to the existence, perfection and
priority of the Liens and security interests provided herein and therein) shall
not be modified, altered or impaired in any manner by any other financing or
extension of credit or incurrence of Indebtedness by the Company, or by any
other act or omission whatsoever. To the fullest extent provided by applicable
law, notwithstanding any such order, financing, extension, incurrence,
dismissal, conversion, act or omission:

               (a) subject to the provisions of the Liquidity Facility
Intercreditor Agreement and the Senior Notes Intercreditor Agreement, the Liens
and security interests granted by the Company to the Trustee (for its benefit
and for the benefit of the Holders) by and pursuant to Section 10.2 hereof shall
constitute valid, binding, continuing, enforceable and fully-perfected first
priority Liens, subject only to Permitted Priority Liens, to which such Liens
and security

                                       74
<PAGE>

interests shall be subordinate and junior, and shall be prior to all other Liens
and interests, now existing or hereafter arising, in favor of any other creditor
or any other Person whatsoever; and

               (b) the Liens and security interests granted by the Company to
the Trustee (for its benefit and for the benefit of the Holders) by and pursuant
to Section 10.2 hereof shall continue to be valid, binding, continuing,
enforceable and fully-perfected without the necessity for the Trustee to file
any financing statements or to otherwise perfect such Liens and security
interests under applicable non-bankruptcy law.

               Section 10.9 Recording and Opinions. The Company will cause this
Indenture, the applicable Collateral Documents and any financing statements, and
all amendments or supplements to each of the foregoing and any other similar
security documents as necessary, to be registered, recorded and filed or
re-recorded, re-filed and renewed in such manner and in such place or places, if
any, as may be required by law or reasonably requested by the Trustee in order
fully to preserve and protect the Liens securing the obligations under the Notes
pursuant to this Indenture and the other Collateral Documents, except as
otherwise provided herein and therein. For the avoidance of doubt and without
limiting the rights of the Trustee under Section 9-509(b) of the UCC, the
Company hereby authorizes the Trustee to file financing statements and
amendments thereto with respect to the Collateral (including after-acquired
Collateral).

               The Company shall furnish to the Trustee:

               (a) promptly after the execution and delivery of this Indenture,
and promptly after the execution and delivery of any other instrument of further
assurance or amendment, an Opinion of Counsel in Bermuda either (i) stating
that, subject to customary assumptions and exclusions, in the opinion of such
counsel, this Indenture, the applicable Collateral Documents and all other
instruments of further assurance or amendment have been properly recorded,
registered and filed to the extent necessary to make effective the Liens
intended to be created by the Collateral Documents with respect to the Equity
Interests of any Foreign Subsidiary of the Company existing under the laws of
Bermuda and reciting the details of such action or referring to prior Opinions
of Counsel in which such details are given or (ii) stating that, subject to
customary assumptions and exclusions, in the opinion of such counsel, no such
action is necessary to make such Lien effective as intended by such Collateral
Documents;

               (b) within 30 days after January 1, in each year beginning with
the year 2003, an Opinion of Counsel, dated as of such date, either (i) stating
that, subject to customary assumptions and exclusions, in the opinion of such
counsel, such action has been taken with respect to the recording, registering,
filing, re-recording, re-registering and re-filing of this Indenture and all
supplemental indentures, financing statements, continuation statements or other
instruments of further assurance as is necessary to maintain the Liens of this
Indenture and the other Collateral Documents with respect to the Equity
Interests of any Foreign Subsidiary of the Company existing under the laws of
Bermuda until the next Opinion of Counsel is required to be rendered pursuant to
this paragraph and reciting the details of such action or referring to prior
Opinions of Counsel in which such details are given or (ii) stating that,
subject to customary assumptions and exclusions, in the opinion of such counsel,
no such action is necessary to maintain such Lien, until the next Opinion of
Counsel is required to be rendered pursuant to this paragraph; and

                                       75
<PAGE>

               (c) the certificates or opinions, as the case may be, required by
TIA Section 314(d). Such certificates or opinions will be subject to the terms
of TIA Section 314(e).

               Section 10.10 Protection of the Trust Estate. Subject to the
terms of this Indenture, the other Collateral Documents, the Liquidity Facility
Intercreditor Agreement and the Senior Notes Intercreditor Agreement, upon prior
written notice to the Company, the Trustee shall have the power (i) to institute
and maintain such suits and proceedings as it may deem expedient, to prevent any
impairment of the Collateral under this Indenture or any of the other Collateral
Documents and in the profits, rents, revenues and other income arising
therefrom, including the power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or order
would impair any Collateral or be prejudicial to the interests of the Holders of
Notes or the Trustee, to the extent permitted thereunder; and (ii) to enforce
the obligations of the Company or any Subsidiary under this Indenture or the
other Collateral Documents. Upon receipt of notice that the Company is not in
compliance with any of the requirements of any Deed of Trust, the Trustee may,
but shall have no obligation to purchase, at the Company's expense, such
insurance coverage necessary to comply with the appropriate section of the Deed
of Trust.

               Section 10.11 Certificates of the Company. The Company shall
furnish to the Trustee, prior to each proposed release of Collateral pursuant to
this Indenture or the other Collateral Documents, (i) all documents required by
TIA Section 314(d) and (ii) an Opinion of Counsel in the United States, which
may be rendered by internal counsel to the Company, to the effect that, subject
to customary assumptions and exclusions, such accompanying documents constitute
all documents required by TIA Section 314(d). The Trustee may, to the extent
permitted by Sections 7.1 and 7.2 hereof, accept as conclusive evidence of
compliance with the foregoing provisions the appropriate statements contained in
such documents and such Opinion of Counsel.

               Section 10.12 Certificates of the Trustee. In the event that the
Company wishes to release Collateral in accordance with this Indenture or the
other Collateral Documents and has delivered the certificates and documents
required by this Indenture or the other Collateral Documents and Sections 10.3
and 10.10 hereof, the Trustee shall determine whether it has received all
documentation required by TIA Section 314(d) in connection with such release.

               Section 10.13 Authorization of Actions to Be Taken by the Trustee
Under the Collateral Documents, the Liquidity Facility Intercreditor Agreement
and the Senior Notes Intercreditor Agreement. Subject to the provisions of
Sections 7.1, 7.2, 7.3 and 9.2 hereof, the Trustee may and without the consent
of the Holders of Notes, on behalf of the Holders of Notes, take all actions it
deems necessary or appropriate in order to (a) enforce any of the terms of this
Indenture, the Liquidity Facility Intercreditor Agreement, the Senior Notes
Intercreditor Agreement or the other Collateral Documents and (b) collect and
receive any and all amounts payable in respect of the Obligations of the Company
hereunder, including, but not limited to, the appointment and approval of
Collateral Agents and the appointment and approval of an insurance trustee. The
Trustee shall have power to institute and maintain such suits and proceedings as
it may deem expedient to prevent any impairment of the Collateral by any acts
that may be unlawful or in violation hereof or of the other Collateral
Documents, the Liquidity

                                       76
<PAGE>

Facility Intercreditor Agreement or the Senior Notes Intercreditor Agreement,
and such suits and proceedings as the Trustee may deem expedient to preserve or
protect its interests and the interests of the Holders of Notes in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or order
would impair the security interest hereunder or under any of the other
Collateral Documents or be prejudicial to the interests of the Holders of Notes
or of the Trustee).

               Section 10.14 Trustee's Duties. The powers and duties conferred
upon the Trustee by this Article 10 are solely to protect the Collateral and,
subject to Section 7.1, shall not impose any duty upon the Trustee to exercise
any such powers and duties except as expressly provided in this Indenture.
Neither the Trustee nor any Holder shall be under any duty to the Company
whatsoever to make or give any presentment, demand for performance, notice or
nonperformance, protest, notice of protest, notice of dishonor, or other notice
or demand in connection with any Collateral or to take any steps necessary to
preserve this Indenture. Neither the Trustee nor any Holder shall be liable to
the Company for failure to collect or realize upon any or all of the Collateral,
or for any delay in doing so, nor shall the Trustee or any Holder be under any
duty to the Company to take any action whatsoever with regard thereto. Neither
the Trustee nor any Holder shall have any duty to the Company to comply with any
recording, filing or other legal requirements necessary to establish or maintain
the validity, priority or enforceability of the Liens in, or the Trustee's
rights in or to, any of the Collateral or to perform on behalf of the Company
under this Indenture or any other Collateral Documents or otherwise.

               Section 10.15 Authorization of Receipt of Funds by the Trustee
Under the Collateral Documents. Subject to the provisions of the Liquidity
Facility Intercreditor Agreement and the Senior Notes Intercreditor Agreement,
upon an Event of Default and so long as such Event of Default continues, the
Trustee may exercise in respect of the Collateral, in addition to the other
rights and remedies provided for in this Indenture, in the Collateral Documents
or otherwise available to it, all of the rights and remedies of a secured party
under the UCC or other applicable law, and the Trustee may also upon obtaining
possession of the Collateral as set forth herein, without notice to the Company,
except as specified below, sell the Collateral or any part thereof in one or
more parcels at public or private sale, at any exchange, broker's board or at
any of the Trustee's offices or elsewhere, for cash, on credit or for future
delivery, and upon such other terms as are commercially reasonable. The Company
acknowledges and agrees that any such private sale may result in prices and
other terms less favorable to the seller than if such a sale were a public sale.
The Company agrees that, to the extent notice of sale shall be required by law,
at least ten (10) days' notice to the Company of the time and place of any
public sale or the time after which any private sale is to be made shall
constitute reasonable notification. The Trustee shall not be obligated to make
any sale regardless of notice of sale having been given. The Trustee may adjourn
any public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at the
time and place to which it was so adjourned.

               Any cash that is Collateral held by the Trustee and all cash
proceeds received by the Trustee in respect of any sale of, collection from, or
other realization upon all or any part of the Collateral shall be applied
(unless otherwise provided for in the Liquidity Facility

                                       77
<PAGE>

Intercreditor Agreement, the Senior Notes Intercreditor Agreement or Collateral
Documents and after payment of any and all amounts payable to the Trustee
pursuant to this Indenture), as the Trustee shall determine or as the Holders of
the Notes shall direct pursuant to Section 6.5 hereof, (a) against the
obligations for the ratable benefit of the Holders of the Notes, (b) to
maintain, repair or otherwise protect the Collateral or (c) to take such other
action to protect the other rights of the Holders of the Notes or to take any
other appropriate action or remedy for the benefit of the Holders of the Notes.
Any surplus of such cash or cash proceeds held by the Trustee and remaining
after payment in full of all the Obligations in accordance with Section 6.10
shall be applied in accordance with Section 6.10.

               Section 10.16 Cooperation of Trustee. In the event the Company or
any Subsidiary pledges or grants a security interest in additional Collateral,
the Trustee shall cooperate with the Company or such Subsidiary in reasonably
and promptly agreeing to the form of, and executing as required, any instruments
or documents necessary to make effective the security interest in the Collateral
to be so substituted or pledged. To the extent practicable, the terms of any
security agreement or other instrument or document necessitated by any such
substitution or pledge shall be comparable to the provisions of this Indenture
and the existing Collateral Documents. Subject to, and in accordance with, the
requirements of this Article 10 and the terms of the Collateral Documents, in
the event that the Company engages in any transaction pursuant to Section 10.3
hereof, the Trustee shall cooperate with the Company in order to facilitate such
transaction in accordance with any reasonable time schedule proposed by the
Company, including by delivering and releasing the Collateral in a prompt and

instrumentality, domestic or foreign (including, without limitation, those

respect of the outstanding Notes shall be held in trust and applied by the

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, may at the expense of

               Section 12.1 Notes Subordinate to Senior Indebtedness Only. The
Company covenants and agrees, and each Holder of a Note, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
set forth in the Intercreditor Agreements and in this Article 12 (in each case
subject to the provisions of Article 8 and Article 11), the payment of the
principal of (and premium, if any) and interest (other than increases (if any)
in principal from the addition of deferred interest in accordance with the Notes
and this Indenture), on the Notes are subordinate in right of payment only to
the prior payment in full of all Senior Indebtedness, but not to any other
Indebtedness or other liabilities or obligations of the Company or any other
Person.

               Section 12.2 Trustee to Effectuate Subordination. Each Holder of
a Note by his acceptance thereof authorizes and directs the Trustee on such
Holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article and appoints the Trustee
his attorney-in-fact for any and all such purposes, including, in the event of
any dissolution, winding up, liquidation or reorganization of the Company
(whether in bankruptcy, insolvency, receivership, reorganization or similar
proceedings or upon an assignment for the benefit of creditors or otherwise),
the filing of a claim for the unpaid balance of such Holder's Notes in the form
required in those proceedings and the causing of such claim to be approved.

               Section 12.3 Notice to Trustee. The Company shall give prompt
written notice to the Trustee and any Paying Agent of any default or event of
default under any Senior Indebtedness or under any agreement pursuant to which
any Senior Indebtedness may have been issued or as to any other fact known to
the Company which would prohibit the making of any payment to or by the Trustee
in respect of the Notes. Notwithstanding the provisions of this Article 12 or
any other provision of this Indenture, the Intercreditor Agreements or any other
Collateral Documents, the Trustee shall not be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee in respect of the Notes, pursuant to the provisions in this Article
or the Intercreditor Agreements, unless and until the Trustee shall have
received written notice thereof from the Company or any holder or holders of
Senior Indebtedness or from any trustee therefor or representative thereof; and
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 7.1 hereof, shall be entitled in all respects conclusively
to assume that no such facts exist.

               Section 12.4 Rights of Trustee.

               Nothing in this Article or the Intercreditor Agreements shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
7.7.

                                       82
<PAGE>

               The provisions of this Article shall not be applicable to any
cash, properties or securities received by any Holder that are received as a
holder of any Senior Indebtedness and nothing in this Indenture shall deprive
such Holder of any of its rights as such holder.

               Section 12.5 Defeasance of this Article Twelve. The subordination
of the Notes provided by this Article 12 is expressly made subject to the
provisions for Legal Defeasance or Covenant Defeasance in Article 8 hereof and,
anything herein to the contrary notwithstanding but subject in all respects to
the Intercreditor Agreements, upon the effectiveness of any such Legal
Defeasance or Covenant Defeasance and provided that either a legal defeasance or
covenant defeasance of the Senior Notes in accordance with the Senior Notes
Indenture has become effective, the Notes then outstanding shall thereupon cease
to be subordinated pursuant to this Article Twelve and the Intercreditor
Agreements.

               Section 12.6 This Article Not To Prevent Events of Default. The
failure to make a payment on account of the principal of or interest on the
Notes by reason of any provision of this Article Twelve or the Intercreditor
Agreements will not be construed as preventing the occurrence of an Event of
Default under Section 6.1.

                            ARTICLE 13. MISCELLANEOUS

               Section 13.1 Trust Indenture Act Controls. If any provision of

receives it.

               If the Company mails a notice or communication to Holders, it

obligations of the Company under the Notes, this Indenture, the Liquidity
Facility Intercreditor Agreement, the Senior Notes Intercreditor Agreement, the
other Collateral Documents or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting

               Section 13.11 Severability. In case any provision in this
Indenture or the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be

number of copies of this Indenture. Each signed copy shall be an original, but

consent, waiver or other action provided by this Indenture to be given or taken
by the Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents 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 conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section 13.13.

               (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 a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to such witness, notary or officer the
execution thereof. Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of 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 which the Trustee deems sufficient.

               (c) Notwithstanding anything to the contrary contained in this
Section 13.13, the principal amount and serial numbers of Notes held by any
Holder, and the date of holding the same, shall be proved by the register of the
Notes maintained by the Registrar as provided in Section 2.3 hereof.

               (d) If the Company shall solicit from the Holders of the Notes
any request, demand, authorization, direction, notice, consent, waiver or other
Act, the Company may, at its option, by or pursuant to a resolution of its
Management Committee fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), if the Company at its option elects to so
fix a record date, such record date shall be the record date specified in or
pursuant to such resolution, which shall be a date not earlier than the date 30
days prior to the first solicitation of Holders generally in connection
therewith or the date of the most recent list of Holders forwarded to the
Trustee prior to such solicitation pursuant to Section 2.5 hereof and not later
than the date such solicitation is

                                       86

direction, notice, consent, waiver or other Act may be given before or after

such record date shall be deemed to be Holders for the purposes of determining
whether Holders of the requisite proportion of the then outstanding Notes have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the then
outstanding Notes shall be computed as of such record date; provided, that no
such demand, authorization, direction, notice, consent, waiver or other Act by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after such record date.

consent, waiver or other Act of the Holder of any Note shall bind every
subsequent Holder of the same Note and the Holder of every Note issued upon the
registration or transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Note.

               (f) Without limiting the foregoing, a Holder entitled hereunder
to take any action hereunder with regard to any particular Note may do so itself
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.

in the Notes, express or implied, shall give to any Person, other than the
parties hereto, any Paying Agent, any Registrar and their successors hereunder,
and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.
