                                      -41-


                  Upon any application or request by the Company to the Trustee
to take any action under any provision of this Indenture, the Company shall
furnish to the Trustee such certificates and opinions as it may reasonably
request or as may be required under the Trust Indenture Act. Each such
certificate or opinion shall be given in the form of an Officers' Certificate,
if to be given by an officer of the Company, or an Opinion of Counsel, if to be
given by counsel, and shall comply with the requirements of the Trust Indenture
Act and any other requirement set forth in this Indenture.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

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

         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

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

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

                                      -42-


SECTION 103.      FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

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

                                      -43-


SECTION 104.      ACTS OF HOLDERS; RECORD DATE.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Note shall bind every future
Holder of the same Note and the Holder of every Note issued upon the
registration of 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 reli-

                                      -44-


ance thereon, whether or not notation of such action is made upon such Note.

                  (e) The Company may set any day as a record day for the
purpose of determining the Holders of Outstanding Notes entitled to give, make
or take any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders, PROVIDED THAT the Company may not set a record date for, and
the provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Notes on such record date, and no other Holders, shall be entitled
to take the relevant action, whether or not such Holders remain Holders after
such record date; PROVIDED THAT no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Notes on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder in the manner set forth in Section 106.

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Notes entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding Notes
on such record date, and no other Holders, shall be entitled to join in such
notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; PROVIDED THAT no such action shall be effective
hereunder

                                      -45-


unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Notes on such record date. Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding Notes
on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Company's expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Company in writing and to each Holder in the manner set
forth in Section 106.

                  With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; PROVIDED THAT no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder in the manner set forth in Section 106, on or prior
to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which
set such record date shall be deemed to have initially designated the 180th day
after such record date as the Expiration Date with respect thereto, subject to
its right to change the Expiration Date as provided in this paragraph.

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

                  (g) Notwithstanding any provision herein to the contrary, all
Notes issued under this Indenture shall vote and consent together on all matters
(as to which the Holders may vote or consent) as one class and no series of
Notes

                                      -46-


will have the right to vote or consent as a separate class on any matter.

SECTION 105.      NOTICES, ETC., TO TRUSTEE AND COMPANY.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office
         at United States Trust Company of New York, 114 West 47th Street, New
         York, New York 10036-1532, Attention: Corporate Trust Administration,
         or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to the Trustee by the
         Company.

                  Notice to the Trustee shall not be effective until it is
actually received.

                                      -47-


SECTION 106.      NOTICE TO HOLDERS; WAIVER.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Note
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107.      CONFLICT WITH TRUST INDENTURE ACT.

                  If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be part
of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

                                      -48-


SECTION 108.      EFFECT OF HEADINGS AND TABLE OF CONTENTS.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

SECTION 109.      SUCCESSORS AND ASSIGNS.

                  All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

SECTION 110.      SEPARABILITY CLAUSE.

                  In case any provision in this Indenture or in the Notes shall
be invalid, illegal or unenforceable, the validity, legality and enforceability

accordance with the standing instructions and procedures existing between the
Depositary and the Notes Custodian, the aggregate principal amount of the Global
Note to be reduced accordingly and, following such reduction, the Company shall
execute and, upon receipt of a Company Order, the Trustee shall authenticate and
deliver to the transferee a Definitive Note with the appropriate legend, if
necessary, in the appropriate principal amount.

                  (e) EXCHANGES BETWEEN REGULATION S NOTES AND RULE 144A NOTES.
Prior to the expiration of the restricted period, beneficial interests in the
Regulation S Temporary Global Note may not be transferred to a Person who takes
delivery in the form of an interest in a Rule 144A Global Note. After the
expiration of the restricted period, beneficial interests in Regulation S
Permanent Global Notes may be transferred to a Person who takes delivery in the
form of an interest in a Rule 144A Global Note. Upon receipt by the Trustee of
written instructions or such other form of instructions as is customary for the
Depositary, from the Depositary or its nominee on behalf of any Person having a
beneficial interest in the Regulation S Permanent Global Note, then the Trustee
shall cause, or direct the Notes Custodian to cause, in accordance with the
standing instructions and procedures existing between the Depositary and the
Notes Custodian, the aggregate principal amount of the Regulation S Permanent
Global Note to be decreased and the aggregate principal amount of the Rule 144A
Global Note to be increased by the principal amount of the beneficial interest
in the Regulation S Permanent Global Note to be exchanged, to credit, or cause
to be credited, to the account of the transferor a beneficial interest in the
Rule 144A Global Note equal to the reduction in the aggregate principal amount
of the Regulation S Permanent Global Note, and to debit, or cause to be debited,
from the account of the transferor the beneficial interest in the Regulation S
Permanent Global Note that is being exchanged or transferred.

                  Prior to the expiration of the restricted period, beneficial
interests in the Rule 144A Global Note may not be transferred to any Person that
takes delivery thereof in the form of an interest in the Regulation S Temporary
Global

                                      -61-


Note. After the expiration of the restricted period, beneficial interests in the
Rule 144A Global Note may be transferred to a Person who takes delivery in the
form of an interest in the Regulation S Permanent Global Note only upon receipt
by the Trustee of a written certification from the transferor to the effect that
such transfer is being made in accordance with Rule 904. Upon receipt by the
Trustee of written instructions or such other form of instructions as is
customary for the Depositary, from the Depositary or its nominee on behalf of
any Person having a beneficial interest in the Rule 144A Global Note, then the
Trustee shall cause, or direct the Notes Custodian to cause, in accordance with
the standing instructions and procedures existing between the Depositary and the
Notes Custodian, the aggregate principal amount of the Rule 144A Global Note to
be decreased and the aggregate principal amount of the Regulation S Permanent
Global Note to be increased by the principal amount of the beneficial interest
in the Rule 144A Global Note to be exchanged, to credit, or cause to be
credited, to the account of the transferor a beneficial interest in the
Regulation S Permanent Global Note equal to the reduction in the aggregate
principal amount of the Rule 144A Global Note, and to debit, or cause to be
debited, from the account of the transferor the beneficial interest in the Rule
144A Global Note that is being exchanged or transferred.

                  (f) RESTRICTIONS ON TRANSFER AND EXCHANGE OF REGULATION S
TEMPORARY GLOBAL NOTES. A holder of a beneficial interest in a Regulation S
Temporary Global Note must provide Euroclear or CEDEL, as the case may be, with
a certificate in the form set forth in Exhibit B certifying that the beneficial
owner of the interest in the Regulation S Temporary Global Note is either not a
U.S. Person (as defined in Regulation S) or has purchased such interest in a
transaction that is exempt from the registration requirements under the
Securities Act (the "Regulation S Certificate"), and Euroclear or CEDEL, as the
case may be, must provide to the Trustee (or to the Paying Agent if other than
the Trustee) a certificate in the form set forth in Exhibit B prior to (i) the
payment of interest or principal with respect to such holder of beneficial
interests in the Regulation S Temporary Global Note and (ii) any exchange of
such beneficial interest for a beneficial interest in a Regulation S Permanent
Global Note.

                           AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND
                           "UNITED STATES" HAVE THE MEANINGS GIVEN TO THEM BY

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

                           (ii) Except as permitted by the following paragraphs
         (iii), (iv) and (v), each Regulation S Temporary Global Note (and all

         legend in substantially the form set forth in the form of Note attached
         to this Indenture.

         Restricted Note (including any Transfer Restricted Note represented by
         a Global Note) pursuant to Rule 144 or an effective registration
         statement under the Securities Act:

                                    (A) in the case of any Transfer Restricted
                  Note, the Note Registrar shall permit the Holder thereof to

                                    (B) any such Transfer Restricted Note
                  represented by a Global Note shall not be subject to the
                  provisions set forth in (i), (ii) or (iii) above (such sales
                  or transfers being subject only to the provisions of Section
                  305(c) hereof); PROVIDED, HOWEVER, that with respect to any
                  request for an exchange of a Transfer Restricted Note that is
                  represented by a Global Note for a Definitive Note that does
                  not bear a legend, which request is made in reliance upon Rule
                  144, the Holder thereof shall certify in writing to the Note
                  Registrar that such request is being made pursuant to Rule 144

Exchange Offer shall not bear the legend set forth in (i), (ii) or (iii) above
and the Trustee shall rescind any restriction on the transfer of such Exchange
Notes.

                  (h) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTE. At such
time as all beneficial interests in a Global Note have either been exchanged for
Definitive Notes or beneficial interests in other Global Notes, redeemed,
repurchased or canceled, such Global Note shall be returned to or retained and
canceled by the Trustee. At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for Definitive Notes or a
beneficial interest in another Global Note, redeemed, repurchased or canceled,
the principal amount of Notes represented by such Global Note shall be reduced
and an endorsement shall be made on such Global Note, by the Trustee or the
Notes Custodian, at the direction of the Trustee, to reflect such reduction.

                  (i) OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
DEFINITIVE NOTES. To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Definitive Notes and
Global Notes at the Note Registrar's request.

                  (j) GENERAL. No service charge shall be made for any
registration of transfer or exchange of Notes, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of

                                      -65-


Notes, other than exchanges pursuant to Section 304, 906 or 1108 or in
accordance with any Asset Sale Offer or Change of Control Offer pursuant to
Section 1015 or 1014, respectively, not involving any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Notes selected for redemption under Section 1104 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

SECTION 306.      MUTILATED, DESTROYED, LOST AND STOLEN NOTES.

                  If any mutilated Note is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Note and
(ii) such security or indemnity as may be required by them to save each of them
and any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Note has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a
new Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

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

                  Upon the issuance of any new Note under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other

                                      -66-


expenses (including the fees and expenses of the Trustee) connected therewith.

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

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

SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                  Interest on any Note which is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Note (or one or more Predecessor Notes) is registered at the
close of business on the Regular Record Date immediately preceding such Interest
Payment Date.

                  Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         Predecessor Notes) are registered at the close of business on a Special
         Record Date for the payment of such Defaulted Interest, which shall be
         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         Note and the date of the proposed payment, and at the same time the
         Company shall deposit with the Trustee an amount of

                                      -67-


         money equal to the aggregate amount proposed to be paid in respect of
         such Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder at his address as it appears in the Note
         Register, not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Notes (or
         their respective Predecessor Notes) are registered at the close of
         business on such Special Record Date and shall no longer be payable
         pursuant to the following clause (2).

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

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

                                      -68-


SECTION 308.      PERSONS DEEMED OWNERS.

                  Prior to due presentment of a Note for registration of

than the Trustee, be delivered to the Trustee and shall be promptly canceled by
it. The Company may at any time deliver to the Trustee for cancellation any
Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and all Notes so delivered shall be
promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or
in exchange for any Notes canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Notes held by the Trustee
shall be disposed of as directed by a Company Order.

SECTION 310.      COMPUTATION OF INTEREST.

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

                  The Company in issuing Notes may use "CUSIP" and "ISIN"
numbers (if then generally in use) in addition to serial numbers; if so, the
Trustee shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers
in notices

                                      -69-


of redemption and repurchase as a convenience to Holders; PROVIDED THAT any such
notice may state that no representation is made as to the correctness of such
CUSIP and ISIN numbers either as printed on the Notes or as contained in any
notice of a redemption or repurchase and that reliance may be placed only on the
serial or other identification numbers printed on the Notes, and any such
redemption or repurchase shall not be affected by any defect in or omission of
such CUSIP and ISIN numbers.

expressly provided for), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

                           created after the Issue Date, if that default:

                           (a)      is caused by a failure to pay principal of
                                    or premium, if any, on such Indebtedness
                                    prior to the expiration of the grace period

                           (b)      results in the acceleration of such
                                    Indebtedness prior to its express maturity,

                                      -74-


                           any substantial part of the property of the Company
                           or any of its Restricted Subsidiaries that are

                           making by the Company or any of its Restricted
                           Subsidiaries that are Significant Subsidiaries of the
                           Company of an assignment for the benefit of

                           of corporate action by the Company or any such
                           Significant Subsidiary in furtherance of any such
                           action.

                  In the event of a declaration of acceleration of the Notes
because an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (5) of this Section 501,
the declaration of acceleration of the Notes shall be automatically annulled if
the Holders of any Indebtedness described in clause (5) of this Section 501 have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if:

                  (a)      the annulment of the acceleration of Notes would not
                           conflict with any judgment or decree of a court of
                           competent jurisdiction; and

                  (b)      all existing Events of Default, except nonpayment of
                           principal or interest on the Notes that became due
                           solely because of the acceleration of the Notes, have
                           been cured or waived.

SECTION 502.      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

                  If any Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Outstanding Notes may
declare the principal of the Notes to be due and payable immediately; provided,
that so long as any Indebtedness permitted to be incurred pursuant to the Senior
Credit Facilities shall be outstanding, such acceleration shall not be effective
until the earlier of:

                                      -75-


                  (1)      an acceleration of any such Indebtedness under the
                           Senior Credit Facilities, or

                  (2)      five business days after receipt by the Company and
                           the Chase Manhattan Bank as Administrative Agent to
                           the Senior Credit Facilities at The Chase Manhattan
                           Bank, 270 Park Avenue, New York, New York 10017,
                           Attention: Stephen Rochford (or to such other
                           Administrative Agent as the Trustee may hereafter be
                           notified in writing) of written notice of such
                           acceleration (PROVIDED THAT the notification of the
                           replacement Administrative Agent and its address
                           shall be received by the Trustee prior to the
                           issuance of such notice of acceleration).

                  Notwithstanding the preceding paragraph, in the case of an
Event of Default described in clause (8) or (9) of Section 501, with respect to
the Company or any of its Subsidiaries, the principal and any accrued but unpaid
interest on all Outstanding Notes shall become due and payable immediately
without further action or notice.

                  In the case of any Event of Default occurs on or after August
15, 2004 by reason of any willful action or inaction taken or not taken by or on
behalf of the Company with the intention of avoiding payment of the premium that
the Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to Section 1101 hereof, an equivalent premium shall also become
and be immediately due and payable to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to August 15,
2004 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, an additional premium shall
also become immediately due and payable to the extent permitted by law upon
acceleration of the Notes in an amount, for each of the years beginning on
August 15 of the years set forth below, as set forth below (such total amount
due is expressed as a percentage of the principal amount of the Notes on the
date of payment that would otherwise be due but for the provisions of this
sentence):

                                      -76-


           YEAR                                                       PERCENTAGE

           1999..................................................     113.000%

           2000..................................................     111.700%

           2001..................................................     110.400%

           2002..................................................     109.100%

           2003..................................................     107.800%

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in aggregate principal amount of the Outstanding Notes or the holders
of a supermajority in aggregate principal amount of the Notes with respect to a
default in respect of any provision requiring a supermajority for an amendment
to such provision, as the case may be, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if (1) the
Company has paid or deposited with the Trustee a sum sufficient to pay (A) all
overdue interest on the Notes,(B) the principal of (and premium, if any, on) any
Notes which have become due otherwise than by such declaration of acceleration
(including any Notes required to have been purchased on the Purchase Date
pursuant to an Offer to Purchase made by the Company) and interest thereon at
the rate provided therefor in the Notes,(C) interest upon overdue interest at
the rate provided therefor in the Notes, and(D) all sums paid or advanced by the
Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and (2) all existing Events of
Default, other than the non-payment of the principal of, premium, if any, and
interest (and Liquidated Damages, if any) on the Notes which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

                  No such rescission shall affect any subsequent Default or
impair any right consequent thereon.

                                      -77-


SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                  TRUSTEE.

                  The Company covenants that if

                  (1) default is made in the payment of any interest (and
         Liquidated Damages, if any) on any Note when such interest (and
         Liquidated Damages, if any) becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Note at the Maturity thereof or, with respect
         to any Note required to have been purchased pursuant to an Asset Sale
         Offer or Change of Control Offer made by the Company, at the Purchase
         Date thereof,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the whole amount then due and payable on such Notes for
principal (and premium, if any) and interest (and Liquidated Damages, if any),
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest and Liquidated Damages, at the rate provided by the Notes, and, in
addition thereto, 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.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon the Notes,
wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such judicial proceedings as the Trustee shall deem
appropriate,

                                      -78-


whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

SECTION 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

                  In case of any judicial proceeding relative to the Company (or
any other obligor upon the Notes), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized and directed by each Holder to make such
payments to the Trustee and, in the event that the Trustee requests the making

Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding,

                                      -79-


brought in its own name as trustee of an express trust, and any recovery of

appointment of a receiver or trustee, or for any other remedy hereunder, unless

                  (1) such Holder has previously given written notice to the
Trustee of a continuing Event of Default;

                                      -80-

         the Outstanding Notes shall have made written request to the Trustee to
         institute proceedings in respect of such Event of Default in its own
         name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity reasonably satisfactory to the Trustee against the costs,
         expenses and liabilities to be incurred in compliance with such
         request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,

Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest (and Liquidated Damages, if any) on such Note on the
respective Stated Maturities expressed in such Note (or, in the case of

Change of Control Offer made by the Company and required to be accepted as to
such Note, on the Purchase Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture 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, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510.      RIGHTS AND REMEDIES CUMULATIVE.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph

Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511.      DELAY OR OMISSION NOT WAIVER.

                  No delay or omission of the Trustee or of any Holder of any
Note to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Holders, as
the case may be.

                                      -82-


SECTION 512.      CONTROL BY HOLDERS.

                  The Holders of a majority in aggregate principal amount of the
Outstanding Notes shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, PROVIDED THAT

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or involve the Trustee in personal
         liability, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

SECTION 513.      WAIVER OF PAST DEFAULTS.

                  The Holders of not less than a majority in aggregate principal
amount of the Outstanding Notes may on behalf of the Holders of all the Notes
waive any existing Default hereunder and its consequences, except a default with
respect to any provision requiring a supermajority to amend, which default may
only be waived by such a supermajority, except a Default

                  (1) in the payment of the principal of (or premium, if any) or
         interest (or Liquidated Damages, if any) on any Note (including any
         Note which is required to have been purchased pursuant to an Asset Sale
         Offer or Change of Control Offer which has been made by the Company),
         or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Note affected.

                  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.

                                      -83-


SECTION 514.      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,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs, including reasonable attorney's fees and expenses, against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
PROVIDED, that neither this Section nor the Trust Indenture Act shall be deemed
to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Trustee or the Company.

SECTION 515.      WAIVER OF USURY, STAY OR EXTENSION LAWS.

                  The Company covenants (to the extent that it may lawfully do
so) that it shall not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it shall not hinder, delay or
impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had
been enacted.

     own funds or otherwise incur any financial liability in the performance of
     any of its duties hereunder, or in the exercise of any of its rights or
     powers, if it shall have reasonable grounds for believing that repayment of
     such funds or adequate indemnity against such risk or liability is not
     reasonably assured to it. Whether or not therein expressly so provided,
     every provision of this Indenture relating to the conduct or affecting the
     liability of or affording protection to the Trustee shall be subject to the
     provisions of this Section.

         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

                  (c) The Trustee shall have no liability except for its own
     negligent action, its own negligent failure to act, or its own willful
     misconduct, except that:

                  (2) 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.

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith

                                      -85-

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, premium, if any, or
interest on any Note, the Trustee may withhold the notice if and so long as the
board of directors, the executive committee or a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of the Holders.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

         incurred by it in compliance with such request or direction;

         inquiry or investigation, it shall be entitled, upon reasonable prior

         personally or by agent or attorney, at such reasonable times as
         reasonably requested; and

                  The recitals contained herein and in the Notes, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee

                                      -87-


assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the

Company of the Notes or the proceeds thereof.

SECTION 605.      MAY HOLD NOTES.

                  The Trustee, any Paying Agent, any Note Registrar or any other
agent of the Company, in its individual or any other capacity, may become the
owner or pledgee of Notes and, subject to Sections 608 and 613, may otherwise
deal with the Company with the same rights it would have if it were not Trustee,
Paying Agent, Note Registrar or such other agent.

         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to

         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                                      -88-

         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the

collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal of or interest on particular Notes.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 501(8) or (9) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

within the meaning of the Trust Indenture Act, the Trustee shall eliminate such

requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus

                                      -89-


of such Person shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 611.

                  (b) The Trustee may resign at any time by giving written
notice thereof to the Company. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the

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

competent jurisdiction for the appointment of a successor Trustee.

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Note for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its

                                      -90-


         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Note for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 106. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

                  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument

surrendered for payment, where Notes may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company 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, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

                  The Company may also from time to time designate one or more
other offices or agencies (in or outside the Borough of Manhattan, The City of
New York) 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.

SECTION 1003.     MONEY FOR NOTE PAYMENTS TO BE HELD IN TRUST.

it shall, on or before each due date of the principal of (and premium, if any)
or interest (and Liquidated Damages, if any) on any of the Notes, segregate and
hold in trust for the benefit of the Persons entitled thereto a sum sufficient
to pay the principal (and premium, if any) or interest (and Liquidated Damages,
if any) so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and shall promptly notify the Trustee
of its action or failure so to act.

                                     -102-



                  Whenever the Company shall have one or more Paying Agents, it

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

                  The Company shall cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent shall:

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

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

                  (3) at any time during the continuance of any such Default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

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

                                      -103-


                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest (and Liquidated Damages, if any) on any Note and
remaining unclaimed for two years after such principal (and premium, if any) or
interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Note shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; 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 a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, 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 publication, any unclaimed balance of
such money then remaining shall be repaid to the Company.

SECTION 1004.     EXISTENCE.

                  Subject to Article Eight and Section 1015, the Company and its
Restricted Subsidiaries shall do or cause to be done all things necessary to
preserve and keep in full force and effect their existence, rights (charter and
statutory) and franchises; PROVIDED, HOWEVER, that the Company and Restricted
its Subsidiaries shall not be required to preserve any such right or franchise
if the Board of Directors of the Company in good faith shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company or its Restricted Subsidiaries and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1005.     MAINTENANCE OF PROPERTIES.

                                      -104-

conduct of its business or the business of any Restricted Subsidiary of the
Company to be maintained and kept in good condition, repair and working order

necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent the
Company from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, as determined by the Board of Directors of
the Company in good faith, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

SECTION 1006.     PAYMENT OF TAXES AND OTHER CLAIMS.

                  The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges levied or imposed upon the Company or any of its
Restricted Subsidiaries or upon the income, profits or property of the Company
or any of its Restricted Subsidiaries, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any of its Restricted Subsidiaries; PROVIDED,
HOWEVER, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders.

SECTION 1007.     MAINTENANCE OF INSURANCE.

                  The Company shall, and shall cause its Restricted Subsidiaries
to, keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible or in the case of insurance coverage, to self insure in each case to
the extent, in the judgment of the Company, to do so comports with good business
practice.

Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,

(including Acquired Debt) and issue Disqualified Stock or preferred stock if the
Fixed Charge Coverage Ratio for the Company's most recently ended four full

immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Stock or preferred stock is issued (i) for such dates from
the Issue Date up to but not including September 30, 2000, would have been at
least 2 to 1; (ii) for such dates from September 30, 2000 up to but not
including March 31, 2001, would have been at least 2.25 to 1; and (iii)

basis (including a PRO FORMA application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred, or the Disqualified Stock or
preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period.

                  As long as no Default shall have occurred and be continuing or
would be caused thereby, the first paragraph of this Section 1008 shall not
prohibit the incurrence of any of the following items of Indebtedness

                           including all Permitted Refinancing Indebtedness
                           incurred to refund, refinance or replace any other
                           Indebtedness incurred pursuant to this clause (14),
                           not to exceed $25 million.

                  For purposes of determining compliance with this Section 1008,
in the event that an item of proposed Indebtedness meets the criteria of more
than one of the categories of Permitted Debt described in clauses (1) through
(14) above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Company shall be permitted to classify such item of Indebtedness
in any manner that complies with this covenant. In addition, the Company may, at
any time, change the classification of an item of Indebtedness (or any portion
thereof) to any other clause or to the first paragraph hereof PROVIDED THAT the
Company would be permitted to incur such item of Indebtedness (or the portion
thereof) pursuant to such other clause or the first paragraph hereof, as the
case may be, at such time of reclassification. Accrual of interest, accretion or
amortization of original issue discount and the accretion of accreted value
shall not be deemed to be an incurrence of Indebtedness for purposes of this
covenant.

be the fair market value on the date of the Restricted Payment of the asset(s)
or securities proposed to be transferred or issued by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined in good
faith by the Board of Directors of the Company whose resolution with respect
thereto shall be delivered to the Trustee. The Board of Directors' determination
must be based upon an opinion or appraisal issued by an accounting, appraisal or
investment banking firm of national standing if such fair market value exceeds
$20 million. Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the

provisions restricting subletting or assignment of any lease entered into in the
ordinary course of business, consistent with industry practice, nor (b) Liens
permitted under the terms of this Indenture shall in and of themselves be
considered a restriction on the ability of the applicable Restricted Subsidiary
to transfer such agreement or assets, as the case may be.

SECTION 1011.     LIMITATION ON LIENS SECURING INDEBTEDNESS.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind securing trade payables,
Attributable Debt or Indebtedness that does not constitute Senior Indebtedness
(other than Permitted Liens) upon any of their property or assets, now owned or
hereafter acquired unless:

                  (1)      in the case of Liens securing Indebtedness that is
                           expressly subordinated or junior in right of payment
                           to the Notes, the Notes are secured on a senior basis
                           to the obligations so secured until such time as such
                           obligations are no longer secured by a Lien; and

                  (2)      in all other cases, the Notes are secured on an equal
                           and ratable basis with the obligations so secured
                           until such time as such obligations are no longer
                           secured by a Lien.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets

                                     -119-

understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate or any affiliated professional associations or professional
corporations which employ physicians and other professionals who provide
healthcare services for the Company's occupational and health services centers
(each, an "Affiliate Transaction"), unless:

                  (1)      such Affiliate Transaction is on terms that are no
                           less favorable to the Company or the relevant
                           Restricted Subsidiary than those that would have been
                           obtained in a comparable transaction by the Company
                           or such Restricted Subsidiary made on an arm's-length
                           basis with an unrelated Person; and

                  (2)      the Company delivers to the Trustee:

                                    series of related Affiliate Transactions
                                    involving aggregate consideration in excess

                                    Directors set forth in an Officers'

                                    Transaction complies with clause (1) above
                                    and that such Affiliate Transaction has been
                                    approved by a majority of the disinterested
                                    members of the Board of Directors of the
                                    Company; and

                                    of $15 million, an opinion as to the
                                    fairness to the holders of such Affiliate
                                    Transaction from a financial point of view
                                    issued by an accounting, appraisal or

                           the Board of Directors' determination must be based

                                    Subsidiary Guarantee), that are assumed by
                                    the transferee of any such assets pursuant
                                    to a customary novation agreement that
                                    releases the Company or such Restricted
                                    Subsidiary from further liability; and

                           (b)      any securities, notes or other obligations
                                    received by the Company or any such
                                    Restricted Subsidiary from such transferee
                                    that are contemporaneously (subject to
                                    ordinary settlement periods) converted by
                                    the Company or such Restricted Subsidiary

                                    conversion).

                  The 75% limitation referred to above shall not apply to any
Asset Sale in which the cash or Cash Equivalents portion of the consideration
received therefrom, determined in accordance with the preceding sentence, is
equal to or greater than what the after-tax proceeds would have been had such
Asset Sale complied with the 75% limitation.

Asset Sale, the Company or any such Restricted Subsidiary may apply such Net
Proceeds, at its option:

                           Business;

                  (4)      to acquire other assets (other than securities) that
                           are used or useful in a Permitted Business; or

                  (5)      to make an Asset Sale Offer, treating the Net
                           Proceeds as Excess Proceeds for all purposes.

                  Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph shall constitute "Excess
Proceeds". When the aggregate amount of Excess Proceeds exceeds $15 million, the
Company shall be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
shall be equal to 100% of the principal amount plus accrued and unpaid interest,
if any, to the Purchase Date, and shall be payable in cash. If any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Company may use
such Excess Proceeds for general corporate purposes. If the aggregate principal
amount of Notes tendered into such Asset

                                     -127-


Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale
Offer, the amount of Excess Proceeds shall be reset at zero.

                  To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture relating to such
Asset Sale Offer, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

SECTION 1016.     INVESTMENT COMPANY.

                  The Company shall not, and shall not permit any of its
Subsidiaries to, be required to register as an "Investment Company" (as that
term is defined in the Investment Company Act of 1940, as amended), or otherwise
become subject to registration under the Investment Company Act.

SECTION 1017.     LIMITATIONS ON ISSUANCES OF GUARANTEES OF INDEBTEDNESS.

                  The Company shall not permit any Restricted Subsidiary,
directly or indirectly, to incur Indebtedness or Guarantee or pledge any assets
to secure the payment of any Indebtedness of the Company or any Restricted
Subsidiary unless either such Restricted Subsidiary (1) is a Guarantor or (2)
simultaneously executes and delivers a supplemental indenture to this Indenture
and becomes a Guarantor, which Guarantee shall (a) with respect to any Guarantee
of Senior Indebtedness, be subordinated in right of payment on the same terms as
the Notes are subordinated to such Senior Indebtedness and (b) with respect to
any Guarantee of any other Indebtedness, be senior to or PARI PASSU with such
Restricted Subsidiary's other Indebtedness or Guarantee of or pledge to secure
such other Indebtedness.

                  Notwithstanding the preceding paragraph, any Subsidiary
Guarantee of the Notes shall provide by its terms that it shall be automatically
and unconditionally released and discharged:

                  (1)      in connection with any sale or other disposition of
                           all or substantially all of

                           the assets of that Guarantor (including by way of
                           merger or consolidation) if the Company applies the
                           Net Proceeds of that sale or other disposition in
                           accordance with the applicable provisions of this
                           Indenture; or

                  (2)      in connection with the sale of all of the Capital
                           Stock of a Guarantor if the Company applies the Net
                           Proceeds of that sale in accordance with the
                           applicable provisions of this Indenture; or

                  (3)      if the Company designates such Restricted Subsidiary
                           that is a Guarantor as an Unrestricted Subsidiary.

SECTION 1018.     ADDITIONAL GUARANTEES.

                  If the Company shall acquire or create a Restricted Subsidiary
after the Issue Date, or if any Subsidiary of the Company becomes a Restricted
Subsidiary, then such newly acquired or created Restricted Subsidiary (other
than a Permitted Joint Venture) shall become a Guarantor and execute a
supplemental indenture that subjects such Person to the provisions of this
Indenture as a Guarantor and the Company shall deliver an Opinion of Counsel to
the Trustee, in accordance with the terms of this Indenture, stating that such
supplemental indenture and such Person's obligations under its Subsidiary
Guarantee and this Indenture constitute valid, legal, binding and enforceable
obligations of such Person (subject to customary exceptions concerning
creditors' rights and to equitable principles as may be acceptable to the
Trustee).

SECTION 1019.     LIMITATION ON LINES OF BUSINESS.

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any business other than a Permitted Business.

SECTION 1020.     ANTI-LAYERING.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, incur, create, issue,

                                     -129-

                  (2)      senior in any respect in right of payment to the
                           Notes.

                  No Guarantor shall incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is both:

                  (1)      subordinate or junior in right of payment to any
                           Senior Indebtedness of such Guarantor; and

                  (2)      senior in any respect in right of payment to the
                           Subsidiary Guarantees.

SECTION 1021.     SALE AND LEASEBACK TRANSACTIONS.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, enter into any sale and leaseback transaction;
PROVIDED THAT the Company or any Restricted Subsidiary may enter into a sale and
leaseback transaction if:

                  (1)      the Company or such Restricted Subsidiary could have
                           (a) incurred Indebtedness in an amount equal to the
                           Attributable Debt relating to such sale and leaseback
                           transaction under the Fixed Charge Coverage Ratio
                           test in the first paragraph of Section 1008 and (b)
                           incurred a Lien to secure such Indebtedness pursuant
                           to Section 1011;

                  (2)      the gross cash proceeds of that sale and leaseback
                           transaction are at least equal to the fair market
                           value, as determined in good faith by the Board of
                           Directors of the Company and set forth in an
                           Officers' Certificate delivered to the Trustee, of
                           the property that is the subject of such sale and
                           leaseback transaction; and

                                     -130-


                  (3)      the transfer of assets in such sale and leaseback
                           transaction is permitted by, and the Company applies
                           the proceeds of such transaction in compliance with

SECTION 1022.     [NOT USED]

SECTION 1023.     DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

                  The Board of Directors of the Company may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would
not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, all outstanding Investments owned by the Company and its Restricted
Subsidiaries (except to the extent repaid in cash) in the Subsidiary so
designated shall be deemed to be Restricted Payments at the time of such
designation (to the extent not designated a Permitted Investment) and shall
reduce the amount available for Restricted Payments under the first paragraph of
Section 1009. All such outstanding Investments shall be valued at their fair
market value at the time of such designation, as determined in good faith by the
Board of Directors of the Company. That designation shall only be permitted if
such Restricted Payment would be permitted at that time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The
Board of Directors of the Company may redesignate any Unrestricted Subsidiary to
be a Restricted Subsidiary if the redesignation would not cause a Default.

SECTION 1024.     ADVANCES OF SUBSIDIARIES.

                  All advances to Restricted Subsidiaries made by the Company
after the Issue Date shall be evidenced by intercompany notes in favor of the
Company in the form of Exhibit D. Each intercompany note shall be payable upon
demand and shall bear interest at the same rate as the Notes.

                                     -131-


SECTION 1025.     PAYMENTS FOR CONSENTS.

                  The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes unless such consideration is offered to be paid and is paid to all
Holders that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

SECTION 1026.     STATEMENT BY OFFICERS AS TO
                  DEFAULT; COMPLIANCE CERTIFICATES.

                  (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year an Officers' Certificate, stating whether or
not to the best knowledge of the signers thereof the Company is in default in
the performance and observance of any of the terms, provisions and conditions of
Section 801 or Sections 1004 to 1025, inclusive, and if the Company shall be in
default, specifying all such Defaults and the nature and status thereof of which
they may have knowledge.

                  (b) The Company shall deliver to the Trustee, as soon as
possible and in any event within 10 days after the Company becomes aware or
should reasonably become aware of the occurrence of a Default or an Event of
Default, an Officers' Certificate setting forth the details of such Default or
Event of Default, and the action which the Company proposes to take with respect
thereto.

                  (c) So long as not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
Company shall deliver to the Trustee within 90 days after the end of each fiscal
year a written statement by the Company's independent public accountants stating
(A) that their audit examination has included a review of the terms of this
Indenture and the Notes as they relate to accounting matters, and (B) whether,
in connection with their audit examination, any Default has come to their
attention and, if such a Default has come to their attention, specifying the
nature and period of the existence thereof.

                                     -132-


SECTION 1027.     WAIVER OF COVENANTS.

                  The Company may omit in any particular instance to comply with
any covenant or condition set forth in Section 801 and Sections 1004 to 1025, if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Notes shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect; PROVIDED, HOWEVER, with respect to any provision requiring a
supermajority approval to waive, such provision may only be waived by such a
supermajority, and with respect to a covenant or provision which cannot be
modified or amended without the consent of the Holder of each outstanding Note
affected, such provision may only be waived by the consent of each and every
Holder of outstanding Note affected.

at the election of the Company of less than all the Notes, the Company shall, at
least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such

of any redemption of Notes prior to the expiration of any restriction on such
redemption provided in the terms of such Notes or elsewhere in this Indenture,
the Company shall furnish the Trustee with an Officers' Certificate evidencing

                  (2)      if the Notes are not so listed, on a PRO RATA basis,
                           by lot or by such method as the Trustee shall deem
                           fair and appropriate.

                  The Trustee shall promptly notify the Company and each Note
Registrar in writing of the Notes selected for redemption and, in the case of
any Notes selected for partial redemption, the principal amount thereof to be
redeemed.

                  Notes and portions of Notes selected shall be in amounts of
$1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder
are to be redeemed, the entire outstanding amount of Notes held by such Holder,
even if not a multiple of $1,000, shall be redeemed.

                                     -135-


                  For all purposes of this Indenture, unless the context

         case of partial redemption, a statement to the effect that upon
         surrender of such Notes, a new Note in a principal amount equal to the

         original note;

                  (4) that on the Redemption Date the Redemption Price shall

                                     -136-


SECTION 1106.     DEPOSIT OF REDEMPTION PRICE.

                  Prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) any applicable accrued
interest and Liquidated Damages on, all the Notes which are to be redeemed on
that date. The Trustee or the Paying Agent shall no later than 30 days after the
expiration of the Redemption Date 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 any applicable accrued interest
and Liquidated Damages on, all Notes to be redeemed.

SECTION 1107.     NOTES PAYABLE ON REDEMPTION DATE.

                  Notice of redemption having been given as aforesaid, the Notes
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and any applicable
accrued interest) such Notes or portions of them called for redemption shall not
bear interest. Upon surrender of any such Note for redemption in accordance with
said notice, such Note shall be paid by the Company at the Redemption Price,
together with any applicable accrued interest and Liquidated Damages to the
Redemption Date; provided, however, that installments of interest whose Interest
Payment Date is on or prior to the Redemption Date shall be payable to the

surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate provided by the
Note.

                                     -137-


SECTION 1108.     NOTES REDEEMED IN PART.

                  Any Note which is to be redeemed only in part shall be
surrendered at an office or agency of the Company designated for that purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Note without service
charge, a new Note or Notes, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the

                                     -138-


the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except as to (i) rights of Holders to receive payments
in respect of the principal of, premium, if any, and interest (and Liquidated
Damages, if any) on such Notes when such payments are due from the trust funds;
(ii) the Company's obligations with respect to such Notes concerning Sections
304, 305, 306, 1002 and 1003; (iii) the rights, powers, trust, duties, and
immunities of the Trustee, and the Company's obligations in connection
therewith; and (iv) the Legal Defeasance provisions of this Article Twelve, all
of which shall survive until otherwise terminated or discharged hereunder.
Subject to compliance with this Article Twelve, the Company may exercise its
option under this Section 1202 notwithstanding the prior exercise of its option
under Section 1203.

SECTION 1203.     COVENANT DEFEASANCE.

                  Upon the Company's exercise of the option provided in Section
1201 applicable to this Section, the Company may, at its option and at any time,
elect to have the obligations of the Company and the Guarantors released with
respect to its (i) obligations under Sections 1005 through 1025, inclusive, and
clause (4) of Section 801 and (ii) the occurrence of an event specified in
Sections 501(4), (with respect to any of Sections 1005 through 1025, inclusive),
501(5) and 501(6) shall not be deemed to be a Default, an Event of Default on
and after the date the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"). For this purpose, such Covenant Defeasance means that
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 Section or clause,
whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or clause or by reason of any reference in any such Section or
clause to any other provision herein or in any other document, but the remainder
of this Indenture and such Notes shall be unaffected thereby.

SECTION 1204.     CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

                                     -139-


                  The following shall be the conditions to application of either
Section 1202 or Section 1203 to the then Outstanding Notes:

                  (1) the Company shall irrevocably have deposited or caused to
         be deposited with the Trustee as trust funds in trust for the purpose
         of making the following payments, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of such Notes, in
         U.S. dollars, non-callable Government Securities, or a combination
         thereof, in such amounts as shall be sufficient, in the opinion of a
         nationally recognized firm of independent public accountants, to pay
         the principal of, premium, if any, and interest, Liquidated Damages, if
         any, on the Outstanding Notes on the Stated Maturity of the Notes 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;

                  (2) in the case of an election of Legal Defeasance under
         Section 1202, the Company shall have delivered to the Trustee an
         Opinion of Counsel in the United States 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 Issue Date, 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, subject to customary
         assumptions and exclusions, the Holders of the Outstanding Notes shall
         not recognize income, gain or loss for federal income tax purposes as a
         result of such Legal Defeasance and shall 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;

                  (3) in the case of an election of Covenant Defeasance under
         Section 1203, the Company shall have delivered to the Trustee an
         Opinion of Counsel in the United States reasonably acceptable to the
         Trustee confirming that, subject to customary assumptions and
         exclusions, the Holders of the Outstanding Notes shall not recognize
         income, gain or loss for federal income tax purposes as a result of
         such Covenant Defeasance and shall be subject to federal income tax on
         the same

                                     -140-


         amounts, in the same manner and at the same times as would have been
         the case if such Covenant Defeasance had not occurred;

                  (4) no Default or Event of Default shall have occurred and be
         continuing 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);

                  (5) 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 (other than this Indenture) to which
         the Company or any of its Subsidiaries is a party or by which the
         Company or any of its Subsidiaries is bound;

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

                  (7) no event which is, or after notice or lapse of time or
         both would become, an Event of Default with respect to such Notes or
         any other Notes shall have occurred and be continuing at the time of
         such deposit or, with regard to any such event specified in paragraphs
         (8) or (9) of Section 501, at any time on or prior to the 90th day
         after the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until after such 90th day); and

                  (8) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, which opinion may be
         subject to customary assumptions and exclusions, each stating that all
         conditions precedent provided for relating to either the Legal
         Defeasance under Section 1202 or the Covenant Defeasance under Section
         1203 (as the case may be) have been complied with.

                                     -141-


SECTION 1205.     DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
                  IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee pursuant to Section 1204 in respect of the 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 its own 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 (and premium, if any) and interest
(and Liquidated Damages, if any), but such money need not be segregated from
other funds except to the extent required by law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1204 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the Outstanding Notes.

                  Anything in this Article Twelve to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1204 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 1206.     REINSTATEMENT.

                                     -142-


                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with Section 1202 or 1203 by reason of any order or judgment
of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, or if a Default from a bankruptcy or insolvency
event occurs at any time during the period ending on the 91st day after the date
of a deposit by the Company hereunder, then the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to this Article Twelve until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1202 or 1203; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of (and premium, if any) or interest (and Liquidated Damages, if any)
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 the Paying Agent.


                                ARTICLE THIRTEEN

                                  Subordination

SECTION 1301.     AGREEMENT TO SUBORDINATE.

                  The Company agrees, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Notes and all Obligations in
respect of the Notes (including but not limited to Liquidated Damages) are
subordinated in right of payment, to the extent and in the manner provided in
this Article Thirteen, to the prior payment in full in cash of all Senior
Indebtedness (whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed), and that the subordination is for the benefit
of the holders of Senior Indebtedness.

SECTION 1302.     LIQUIDATION; DISSOLUTION; BANKRUPTCY.

                  Upon any distribution of assets of the Company upon any
Insolvency or Liquidation Proceeding:

                  (1) the holders of all Senior Indebtedness of the Company
         shall be entitled to receive payment in full in cash or Cash
         Equivalents before the Holders shall be

                                     -143-


         entitled to receive any payment on account of the principal of,
         premium, if any, and interest on the Notes or any Obligation in respect
         to the Notes (except that Holders may receive (i) Reorganization
         Securities and (ii) payments made from any defeasance trust created
         pursuant to Section 1201 hereof); and

                  (2) any payment or distribution of assets of the Company of
         any kind or character from any source, whether in cash, property or
         securities (other than (i) Reorganization Securities and (ii) payments
         made from any defeasance trust created pursuant to Section 1201
         hereof), to which the Holders or the Trustee on behalf of the Holders
         would be entitled (by set-off or otherwise), except for this Article,
         shall be paid by the Company or by any receiver, trustee in bankruptcy,
         liquidating trustee, agent or other person making such payment or
         distribution, or by the Holders or by the Trustee if received by them,
         directly to the holders of Senior Indebtedness (PRO RATA to such
         holders on the basis of the amounts of Senior Indebtedness held by such
         holders) or their Representative or Representatives, as their interests
         may appear, for application to the payment of the Senior Indebtedness
         remaining unpaid until all such Senior Indebtedness has been paid in
         full in cash, after giving effect to any concurrent payment,
         distribution or provision therefor to or for the holders of Senior
         Indebtedness.

                                     -144-


SECTION 1303.     DEFAULT ON SENIOR INDEBTEDNESS.

                  (a) In the event of and during the continuation of any default
in the payment of principal of, interest or premium, if any, on any Senior
Indebtedness, or any Obligation owing from time to time under or in respect of
Senior Indebtedness, or in the event that any event of default (other than a
payment default) with respect to any Senior Indebtedness shall have occurred and
be continuing and shall have resulted in such Senior Indebtedness becoming or
being declared due and payable prior to the date on which it would otherwise
have become due and payable, then no payment shall be made by or on behalf of
the Company on account of principal of, premium, if any, and interest (and
Liquidated Damages, if any) on the Notes (other than payments in the form of
Reorganization Securities), unless and until such default shall have been cured
or waived in writing in accordance with the instruments governing such Senior
Indebtedness or such acceleration shall have been rescinded or annulled;

                  (b) If any event of default other than as described in clause
(a) above with respect to any Designated Senior Indebtedness shall have occurred
and be continuing permitting the holders of such Designated Senior Indebtedness
(or their Representative or Representatives) to declare such Designated Senior
Indebtedness due and payable prior to the date on which it would otherwise have
become due and payable, then no payment shall be made by or on behalf of the
Company on account of the principal of, premium, if any, and interest (and
Liquidated Damages, if any) on the Notes (other than payments in the form of
Reorganization Securities) during the period (a "Payment Blockage Period")
commencing on the date the Company or the Trustee receives written notice (a
"Payment Notice") of such event of default (which notice shall be binding on the
Trustee and the Holders as to the occurrence of such a payment default or
nonpayment event of default) from the Credit Agent (or other holders of
Designated Senior Indebtedness or their Representative or Representatives) and
ending on the earliest of:

                           (A)      179 days after such date;

                           (B)      the date, if any, on which such Designated
                                    Senior Indebtedness to which such default
                                    relates is paid in full in cash or

                                     -145-


                                    such default is cured or waived in writing
                                    in accordance with the instruments governing
                                    such Designated Senior Indebtedness by the
                                    holders of such Designated Senior
                                    Indebtedness; and

                           (C)      the date on which the Trustee receives
                                    written notice from the Credit Agent (or
                                    other holders of Designated Senior
                                    Indebtedness or their Representative or
                                    Representatives), as the case may be,
                                    terminating the Payment Blockage Period.

                  (c) During any consecutive 360-day period, the aggregate of
all Payment Blockage Periods shall not exceed 179 days and there shall be a
period of at least 181 consecutive days in each consecutive 360-day period when
no Payment Blockage Period is in effect. No event of default which existed or
was continuing with respect to the Senior Indebtedness for which notice
commencing a Payment Blockage Period was given on the date such Payment Blockage
Period commenced shall be or be made the basis for the commencement of any
subsequent Payment Blockage Period unless such event of default is cured or
waived for a period of not less than 90 consecutive days.

SECTION 1304.     ACCELERATION OF NOTES.

                  If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.

                                     -146-


SECTION 1305.     WHEN DISTRIBUTION MUST BE PAID OVER.

                  In the event that, notwithstanding the other provisions of
this Article Thirteen, the Trustee receives any payment or distribution in
respect of the Notes or of any Obligations with respect to the Notes at a time
when the Trustee has received notice in accordance with Section 1310 that such
payment or distribution is prohibited by Section 1303 hereof, such payment or
distribution shall be held by the Trustee in trust for the benefit of, and shall
be paid forthwith over and delivered, upon written request, to, the holders of
Senior Indebtedness remaining unpaid or unprovided for or their representative
or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments representing any of such Senior Indebtedness may have
been issued, ratably according to aggregate principal amounts remaining unpaid
on account of such Senior Indebtedness held or represented by each, for
application to the payment of all obligations with respect to Senior
Indebtedness remaining unpaid, to the extent necessary to pay or to provide for
the payment of all such obligations in full in cash or Cash Equivalents in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

                  In the event that, notwithstanding the other provisions of
this Article Thirteen, a Holder receives any payment or distribution of any
Obligations with respect to the Notes at a time when such payment or
distribution is prohibited by Section 1303 hereof, such payment or distribution
shall be paid forthwith over and delivered, upon written request, to, the
holders of Senior Indebtedness remaining unpaid or unprovided for or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments representing any of such Senior
Indebtedness may have been issued, ratably according to aggregate principal
amounts remaining unpaid on account of such Senior Indebtedness held or
represented by such, for application to the payment of all obligations with
respect to Senior Indebtedness remaining unpaid, to the extent necessary to pay
or to provide for the payment of all such obligations in full in cash or Cash
Equivalents in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

                                     -147-


                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article Thirteen, and no implied covenants
or obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders or the Company or any other Person money or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
Thirteen, except if such payment is made as a result of the willful misconduct
or gross negligence of the Trustee.

SECTION 1306.     NOTICE BY COMPANY.

                  The Company shall promptly notify the Trustee and the Paying
Agent of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes to violate this Article Thirteen, but
failure to give such notice shall not affect the subordination of the Notes to
the Senior Indebtedness as provided in this Article Thirteen.

SECTION 1307.     SUBROGATION.

                  After all Senior Indebtedness is paid in full in cash or Cash
Equivalents and until the Notes are paid in full, Holders shall be subrogated
(equally and ratably with all other Indebtedness PARI PASSU with the Notes) to
the rights of holders of Senior Indebtedness to receive distributions applicable
to Senior Indebtedness to the extent that distributions otherwise payable to the
Holders have been applied to the payment of Senior Indebtedness. A distribution
made under this Article Thirteen to holders of Senior Indebtedness that
otherwise would have been made to Holders is not, as between the Company and
Holders, a payment by the Company on the Notes. No holder of Senior Indebtedness
shall be obligated to create, warrant, preserve or protect any such subrogation
right or shall suffer any loss or diminution of its rights hereunder if for any
reason such right of subrogation is not available to any Holder.

                                     -148-


SECTION 1308.     RELATIVE RIGHTS.

                  This Article defines the relative rights of Holders and
holders of Senior Indebtedness. Nothing in this Indenture shall:

                  (1) impair, as between the Company and Holders, the obligation
         of the Company, which is absolute and unconditional, to pay principal
         of (and premium, if any) and interest (and Liquidated Damages, if any)
         on the Notes in accordance with their terms;

                  (2) affect the relative rights of Holders and creditors of the
         Company other than their rights in relation to holders of Senior
         Indebtedness; or

                  (3) prevent the Trustee or any Holder from exercising its
         available remedies upon a Default or Event of Default, subject to the
         rights of holders of Senior Indebtedness to receive distributions and
         payments otherwise payable to Holders.

                  If the Company fails because of this Article to pay principal
of (or premium, if any) or interest (or Liquidated Damages, if any) on a Note on
the due date, the failure is still a Default or Event of Default.

SECTION 1309.     SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

                  No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any holder of Senior Indebtedness to comply with this Indenture.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of the Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article Thirteen or the obligations hereunder of
the Holders to the holders of Senior Indebtedness, do any one or more of the
following: (a) change the manner, place or terms of payment

                                     -149-


or extend the time or payment of, or renew or alter, Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; PROVIDED, HOWEVER, that any such alteration shall not (i)
increase the amount of Senior Indebtedness outstanding in a manner prohibited by
this Indenture or (ii) otherwise violate Section 1008 hereof; (b) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (c) release any Person in any manner for
the collection of Senior Indebtedness; and (d) exercise or refrain from
exercising any rights against the Company or any other Person; PROVIDED,
HOWEVER, that in no event shall any such actions limit the right of the Holders
to take any action to accelerate the maturity of the Notes in accordance with
the provisions set forth in Section 502 or to pursue any rights or remedies
against the parties to this Indenture under this Indenture or under applicable
laws if the taking of such action does not otherwise violate the terms of this
Article Thirteen.

SECTION 1310.     RIGHTS OF TRUSTEE AND PAYING AGENT.

                  Notwithstanding the provisions of this Article Thirteen or any
other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment or distribution by the Trustee, and the Trustee and the Paying Agent may
continue to make payments on the Notes, unless the Trustee shall have received
at its Corporate Trust Office at least five Business Days prior to the date of
such payment written notice of facts that would cause the payment of any
Obligations with respect to the Notes to violate this Article Thirteen. Only the
Company or the Representative may give the notice. Nothing in this Article
Thirteen shall impair the claims of, or payments to, the Trustee under or
pursuant to Section 607 hereof.

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness with the same rights it would have if it were not Trustee.

SECTION 1311.     AUTHORIZATION TO EFFECT SUBORDINATION.

                  Each Holder of a Note by the Holder's acceptance thereof
authorizes and directs the Trustee on the Holder's behalf to take such action as
may be necessary or appropriate to effectuate the subordination as provided in
this Article Thirteen, and appoints the Trustee to act as the Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of Indebtedness in the form required in any
proceeding referred to in Section 504 hereof at least 30 days before the
expiration of the time to file such claim, the Representative is hereby
authorized to file an appropriate claim for and on behalf of the Holders.

SECTION 1312.     AMENDMENTS.

                  The provisions of this Article Thirteen or any related
definitions shall not be amended or modified in a manner adverse to the holders
of Senior Indebtedness without the written consent of the holders of all Senior
Indebtedness.


                                ARTICLE FOURTEEN

                              Subsidiary Guarantees

SECTION 1401.     SUBSIDIARY GUARANTEES.


                                     -151-


                  Subject to the provisions of this Article Fourteen, each
Guarantor, jointly and severally, hereby irrevocably and unconditionally fully
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns (the "Subsidiary Guarantee"),
that: (a) the principal of, and premium, if any, and interest (and Liquidated
Damages, if any) on the Notes shall be duly and punctually paid in full when
due, whether at maturity, by acceleration or otherwise, and interest on overdue
principal, and premium, if any, and (to the extent permitted by law) interest on
any interest and Liquidated Damages, if any, on the Notes and all other
obligations of the Company to the Holders or the Trustee hereunder or under the
Notes (including fees, expenses or other) shall be promptly paid in full or
performed, all in accordance with the terms hereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
obligations, the same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed or failing performance of any other obligation of the Company to
the Holders, for whatever reason, each Guarantor shall be obligated to pay, or
to perform or to cause the performance of, the same immediately. An Event of
Default under this Indenture or the Notes shall constitute an event of default
under the Subsidiary Guarantees, and shall entitle the Trustee or the Holders to
accelerate the obligations of each Guarantor hereunder in the same manner and to
the same extent as the obligations of the Company. Each Guarantor hereby agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
with respect to any thereof, the entry of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. Each
Guarantor hereby waives and relinquishes: (a) any right to require the Trustee,
the Holders or the Company (each, a "Benefitted Party") to proceed against the
Company, the Subsidiaries or any other Person or to proceed against or exhaust
any security held by a Benefitted Party at any time or to pursue any other
remedy in any secured party's power before proceeding against the Subsidiaries;
(b) any defense that may arise by reason of the incapacity, lack of

                                     -152-


authority, death or disability of any other Person or Persons or the failure of
a Benefitted Party to file or enforce a claim against the estate (in
administration, bankruptcy or any other proceeding) of any other Person or
Persons; (c) demand, protest and notice of any kind (except as expressly
required by this Indenture), including but not limited to notice of the
existence, creation or incurring of any new or additional Indebtedness or
obligation or of any action or non-action on the part of the Guarantors, the
Company, the Subsidiaries, any Benefitted Party, any creditor of the Guarantors,
the Company or the Subsidiaries or on the part of any other Person whomsoever in
connection with any obligations the performance of which are hereby guaranteed;
(d) any defense based upon an election of remedies by a Benefitted Party,
including but not limited to an election to proceed against the Guarantors for
reimbursement; (e) any defense based upon any statute or rule of law which
provides that the obligation of a surety must be neither larger in amount nor in
other respects more burdensome than that of the principal; (f) any defense
arising because of a Benefitted Party's election, in any proceeding instituted
under the Bankruptcy Law, of the application of Section 1111(b)(2) of the
Bankruptcy Code; and (g) any defense based on any borrowing or grant of a
security interest under Section 364 of the Bankruptcy Code. The Guarantors
hereby covenant that the Subsidiary Guarantees shall not be discharged except by
payment in full of all principal, premium, if any, and interest on the Notes and
all other costs provided for under this Indenture, or except as provided in
Sections 1202 and 1404.

                  If any Holder or the Trustee is required by any court or
otherwise to return to either the Company or the Guarantors, or any trustee or
similar official acting in relation to either the Company or the Guarantors, any
amount paid by the Company or the Guarantors to the Trustee or such Holder, the
Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated
in full force and effect. Each of the Guarantors agrees that it shall not be
entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Each Guarantor agrees that, as between it, on the one hand,
and the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five
hereof for the purposes hereof, notwithstanding any stay, injunction or

                                     -153-


other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article Five hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by such Guarantor for the
purpose of its Subsidiary Guarantee.

SECTION 1402.     EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEES.

                  To evidence the Subsidiary Guarantees set forth in Section
1401 hereof, each of the Guarantors agrees that a Subsidiary Guarantee
substantially in the form of Exhibit C hereto shall be endorsed on each Note
authenticated and delivered by the Trustee and that this Indenture shall be
executed on behalf of such Guarantor by its Chairman of the Board, its President
or one of its Vice Presidents, and attested to by its Secretary or one of its
Assistant Secretaries.

                  Each of the Guarantors agrees that the Subsidiary Guarantees
set forth in this Article Fourteen shall remain in full force and effect and
apply to all the Notes notwithstanding any failure to endorse on each Note a
notation of the Subsidiary Guarantees.

                  If an individual whose manual or facsimile signature is on a
Note shall have ceased to hold such office prior to the authentication and
delivery of the Note on which the Subsidiary Guarantees are endorsed, the
Subsidiary Guarantees shall be valid nevertheless.

                  The delivery of any Note by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the
Subsidiary Guarantees endorsed thereon and set forth in this Indenture and shall
bind each Guarantor notwithstanding the fact that a Subsidiary Guarantee does
not bear the signature of such Guarantor. Each of the Guarantors hereby jointly
and severally agrees that its Subsidiary Guarantee set forth in Section 1401 and
in the form of Subsidiary Guarantee established pursuant to Exhibit C shall
remain in full force and effect notwithstanding any failure to endorse a
Subsidiary Guarantee on any Note.

SECTION 1403.     GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.


                                     -154-


                  (a) Nothing contained in this Indenture or in the Notes shall
         prevent any consolidation or merger of a Guarantor with or into the
         Company or another Guarantor, or shall prevent the transfer of all or
         substantially all of the assets of a Guarantor to the Company or
         another Guarantor. Upon any such consolidation, merger, transfer or
         sale, the Subsidiary Guarantee of such Guarantor shall no longer have
         any force or effect.

                  (b) Except as provided in Section 1403(a), or a transaction
         referred to in Section 1404, no Guarantor shall consolidate with or
         merge with or into (whether or not such Guarantor is the surviving
         corporation) another Person other than the Company or another
         Guarantor, whether in a single transaction or a series of related
         transactions, unless (i) subject to the provisions of Section 1404
         hereof, the Person formed by or surviving any such consolidation or
         merger (if other than such Guarantor) assumes all the obligations of
         such Guarantor in connection with the Subsidiary Guarantees and this
         Indenture pursuant to a supplemental indenture in a form reasonably
         satisfactory to the Trustee, pursuant to which such Person shall
         unconditionally guarantee on a senior subordinated basis all of such
         Guarantor's obligations under such Guarantor's Subsidiary Guarantee and
         this Indenture on the terms set forth in this Indenture; (ii)
         immediately before and immediately after giving effect to such
         transaction on a PRO FORMA basis, no Default or Event of Default shall
         have occurred and be continuing; and (iii) such Guarantor shall have
         delivered to the Trustee an Officers' Certificate and an Opinion of
         Counsel addressed to the Trustee, each stating that such consolidation
         or merger and such supplemental indenture, if any, comply with this
         Indenture and that such supplemental indenture is enforceable. In case
         of any such consolidation or merger and upon the assumption by the
         successor corporation, by supplemental indenture, executed and
         delivered to the Trustee and satisfactory in form to the Trustee, of
         the Subsidiary Guarantees endorsed upon the Notes and the due and
         punctual performance of all of the covenants and conditions of this
         Indenture to be performed by such Guarantor, such successor corporation
         shall succeed to and be substituted for such Guarantor

                                     -155-


         with the same effect as if it had been named herein as a Guarantor.
         Such successor corporation thereupon may cause to be signed any or all
         of the Subsidiary Guarantees to be endorsed upon all of the Notes
         issuable hereunder which theretofore shall have been signed by the
         Company and delivered to the Trustee. All the Subsidiary Guarantees so
         issued shall in all respects have the same legal rank and benefit under
         this Indenture as the Subsidiary Guarantees theretofore and thereafter
         issued in accordance with the terms of this Indenture as though all of
         such Subsidiary Guarantees had been issued at the date of the execution
         hereof.

                  (c) The Trustee, subject to the provisions of Section 1404
         hereof, shall be entitled to receive an Officers' Certificate and an
         Opinion of Counsel as conclusive evidence that any such consolidation,
         merger, sale or conveyance, and any such assumption of obligations,
         comply with the provisions of this Section 1403.

SECTION 1404.     RELEASES FOLLOWING SALE OF ASSETS.

                  Upon the sale or disposition (whether by merger, stock
purchase, asset sale or otherwise) of a Guarantor (or all or substantially all
of the assets of any such Guarantor or 50% or more of the Equity Interests of
any such Guarantor) to an entity which is not a Guarantor or the designation of
a Subsidiary to become an Unrestricted Subsidiary, which transaction is
otherwise in compliance with this Indenture, including without limitation
Section 1015 hereof, such Guarantor shall be deemed released from its
obligations under its Subsidiary Guarantee. Upon delivery by the Company to the
Trustee of an Officer's Certificate and Opinion of Counsel, to the effect that
such sale or other disposition was made by the Company in accordance with the
provisions of this Indenture, including without limitation Section 1015 hereof,
the Trustee shall execute any documents reasonably required in order to evidence
the release of any such Guarantor from its obligations under its Subsidiary
Guarantee. Any Guarantor not released from its obligations under its Subsidiary
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other

                                     -156-


obligations of any Guarantor under this Indenture as provided in this Article
Fourteen.

SECTION 1405.     LIMITATION OF GUARANTOR'S LIABILITY.

                  Each Guarantor, and by its acceptance hereof each Holder,
hereby confirms that it is the intention of all such parties that the guarantee
by such Guarantor pursuant to its Subsidiary Guarantee not constitute a
fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law. To effectuate the foregoing intention, the Holders
and such Guarantor hereby irrevocably agree that the obligations of such
Guarantor under this Article Fourteen shall be limited to the maximum amount as
shall, after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article Fourteen, result in the obligations of such
Guarantor under the Subsidiary Guarantee of such Guarantor not constituting a
fraudulent transfer or conveyance.

SECTION 1406.     APPLICATION OF CERTAIN TERMS AND PROVISIONS TO THE GUARANTORS.

                  (a) For purposes of any provision of this Indenture which
         provides for the delivery by any Guarantor of an Officers' Certificate
         and/or an Opinion of Counsel, the definitions of such terms in Section
         101 shall apply to such Guarantor as if references therein to the
         Company were references to such Guarantor.

                  (b) Any request, demand, authorization, direction, notice,
         consent, waiver or other document which by any provision of this
         Indenture is to be made by any Guarantor, shall be sufficient if
         evidenced as described in Section 105 as if references therein to the
         Company were references to such Guarantor.

                  (c) Any request, demand, authorization, direction, notice,
         consent, waiver or Act of Holders or other document which by any
         provision of this Indenture

                                     -157-


         is required or permitted to be given or served by the Trustee or by any
         Holder may be given or served as described in Section 105 as if
         references therein to the Company were references to such Guarantor.

                  (d) Upon any application or request by any Guarantor to the
         Trustee to take any action under any provision of this Indenture, such
         Guarantor shall furnish to the Trustee such certificates and opinions
         as are required in Section 102 hereof as if all references therein to
         the Company were references to such Guarantor.

SECTION 1407.     RELEASE OF SUBSIDIARY GUARANTEES.

                  Concurrently with the defeasance of the Notes under Section
1202 hereof, the Guarantors shall be released from all of their obligations
under the Subsidiary Guarantees and this Article Fourteen.

SECTION 1408.     SUBORDINATION OF SUBSIDIARY GUARANTEES.

                  The obligations of each Guarantor under its Subsidiary
Guarantee pursuant to this Article Fourteen is subordinated in right of payment
to the prior payment in full in cash of all Senior Indebtedness of such
Guarantor on the same basis as the Notes are subordinated to Senior Indebtedness
of the Company. For the purposes of the foregoing sentence, the Trustee and the
Holders shall have the right to receive and/or retain payments by any of the
Guarantors only at such times as they may receive and/or retain payments in
respect of Notes pursuant to this Indenture, including Article Thirteen hereof.
In the event that the Trustee receives any Guarantor payment at a time when the
Trustee has received notice in accordance with Section 1310, such Guarantor
payment shall be held by the Trustee in trust for the benefit of, and shall be
paid forthwith over and delivered, upon written request, to, the holders of the
Senior Indebtedness of such Guarantor remaining unpaid or unprovided for, for
application to the payment of all obligations with respect to Senior
Indebtedness of such Guarantor remaining unpaid, to the extent necessary to pay
such Senior Indebtedness of such Guarantor in full in accordance with their
terms, after giving effect to any concurrent payment or distribution to

                                     -158-


or for the holders of Senior Indebtedness. In the event that a Holder receives
any Guarantor payment at a time when such payment is prohibited by the second
preceding sentence, such Guarantor payment shall be forthwith paid over and
delivered to the holders of the Senior Indebtedness of such Guarantor remaining
unpaid or unprovided for, for application to the payment of all obligations with
respect to Senior Indebtedness of such Guarantor remaining unpaid, to the extent
necessary to pay such Senior Indebtedness in full in accordance with their
terms, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Indebtedness of such Guarantor.

                  Each Holder of a Note by its acceptance thereof (a) agrees to
and shall be bound by the provisions of this Section 1408, (b) authorizes and
directs the Trustee on the Holder's behalf to take such action as may be
necessary and appropriate to effectuate the subordination so provided, and (c)
appoints the Trustee as the Holder's attorney-in-fact for any and all such
purposes.

SECTION 1409.     WAIVER OF SUBROGATION.


                                     -159-


                  Until this Indenture is discharged and all of the Notes are
discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire
against the Company that arise from the existence, payment, performance or
enforcement of the Company's obligations under the Notes or this Indenture and
each Guarantor's obligations under this Subsidiary Guarantee and this Indenture,
in any such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to
participate in any claim or remedy of the Holders and the Trustees against the
Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Company, directly or indirectly, in cash or other
property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to a Guarantor in
violation of the preceding sentence and any amounts owing to the Trustee or the
Holders under the Notes, this Indenture, or any other document or instrument
delivered under or in connection with such agreements or instruments, shall not
have been paid in full, such amount shall have been deemed to have been paid to
such Guarantor for the benefit of, and held in trust for the benefit of, the
Holders and the Trustee and shall forthwith be paid to the Trustee for the
benefit of such Holders to be credited and applied to the obligations in favor
of the Holders, whether matured or unmatured, in accordance with the terms of
this Indenture. Each Guarantor acknowledges that it has received consideration
for providing the Subsidiary Guarantee and that it shall receive direct and
indirect benefits from the financing arrangements contemplated by this Indenture
and that the waiver set forth in this Section 1409 is knowingly made in
contemplation of such benefits.

SECTION 1410.     IMMEDIATE PAYMENT.

                  Each Guarantor agrees to make immediate payment to the Trustee
on behalf of the Holders of all obligations under the Notes and this Indenture
owing or payable to the Holders upon receipt of a demand for payment therefor by
the Trustee to such Guarantor in writing.

                                     -160-


SECTION 1411.     NO SET-OFF.

                  Each payment to be made by any Guarantor hereunder in respect
of the Notes, the Subsidiary Guarantees or this Indenture shall be payable in
U.S. Dollars and shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature.

SECTION 1412.     OBLIGATIONS ABSOLUTE.

                  The obligations of each Guarantor hereunder are and shall be
absolute and unconditional and any monies or amounts expressed to be owing or
payable by a Guarantor hereunder which may not be recoverable from such
Guarantor on the basis of a guarantee shall be recoverable from such Guarantor
as a primary obligor and principal debtor in respect thereof.

SECTION 1413.     OBLIGATIONS CONTINUING.

                  Subject to Section 1404, the obligations of each Guarantor
hereunder shall be continuing and shall remain in full force and effect until
all the obligations of the Company under the Notes and this Indenture shall have
been paid and satisfied in full.

SECTION 1414.     OBLIGATIONS NOT REDUCED.

                  The obligations of each Guarantor hereunder shall not be
satisfied, reduced or discharged by any intermediate payment or satisfaction of
the whole or any part of the principal, interest, fees and other monies or
amounts which may at any time be or become owing or payable under or by virtue
of or otherwise in connection with the Notes or this Indenture.

SECTION 1415.     OBLIGATIONS REINSTATED.

                  The obligations of each Guarantor hereunder shall continue to
be effective or shall be reinstated, as the case may be, if at any time any
payment which would otherwise have reduced the obligations of a Guarantor
hereunder (whether such payment shall have been made by or on behalf

                                     -161-


of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from
the Holders upon the insolvency, bankruptcy, liquidation or reorganization of
the Company or any Guarantor or otherwise, all as though such payment had not
been made. If demand for, or acceleration of the time for, payment by the
Company is stayed upon the insolvency, bankruptcy, liquidation or reorganization
of the Company, all such indebtedness otherwise subject to demand for payment or
acceleration shall nonetheless be payable by each Guarantor as provided herein.

SECTION 1416.     OBLIGATIONS NOT AFFECTED.

                  The obligations of each Guarantor hereunder shall not be
affected, impaired or diminished in any way by any act, omission, matter or
thing whatsoever, occurring before, upon or after any demand for payment
hereunder (and whether or not known or consented to by a Guarantor or the
Holders) which, but for this provision, might constitute a whole or partial
defense to a claim against a Guarantor hereunder or might operate to release or
otherwise exonerate any Guarantor from any of its obligations hereunder or
otherwise affect such obligations, whether occasioned by default of any of the
Holders or otherwise, including, without limitation:

                  (1) any limitation of status or power, disability, incapacity
         or other circumstance relating to the Company or any other person,
         including any insolvency, bankruptcy, liquidation, reorganization,
         readjustment, composition, dissolution, winding-up or other proceeding
         involving or affecting the Company or any other person;

         in respect of any indebtedness or other obligation of the Company or
         any other person under this Indenture, the Notes or any other document
         or instrument;

                  (3) any failure of the Company, whether or not without fault
         on its part, to perform or comply with any of the provisions of this
         Indenture or the Notes, or to give notice thereof to a Guarantor;

                                     -162-


                  (4) the taking or enforcing or exercising or the refusal or

         against the Company or any other person or their respective assets or
         the release or discharge of any such right or remedy;

                  (5) the granting of time, renewals, extensions, compromises,
         concessions, waivers, releases, discharges and other indulgences to the
         Company or any other person;

                  (6) any change in the time, manner or place of payment of, or
         in any other term of, any of the Notes, or any other amendment,
         variation, supplement, replacement or waiver of, or any consent to
         departure from, any of the Notes or this Indenture, including, without
         limitation, any increase or decrease in the principal amount of or
         premium, if any, or interest on any of the Notes;

                  (7) subject to Section 1404, any change in the ownership,
         control, name, objects, businesses, assets, capital structure or
         constitution of the Company or any Guarantor;

                  (8) subject to Section 1404, any merger or amalgamation of the
         Company or a Guarantor with any person or persons;

                  (9) the occurrence of any change in the laws, rules,
         regulations or ordinances of any jurisdiction by any present or future
         action of any governmental authority or court amending, varying,
         reducing or otherwise affecting, or purporting to amend, vary, reduce
         or otherwise affect, the Notes, this Indenture or the obligations of a
         Guarantor under its Subsidiary Guarantee; and

                  (10) any other circumstance (other than by complete,
         irrevocable payment) that might otherwise constitute a legal or
         equitable discharge or defense of the Company under this Indenture or
         the Notes or of a Guarantor in respect of its Subsidiary Guarantee

which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee, the holders of Senior
Indebtedness and the Holders of the Notes and of the terms upon which the Notes
are, and are to be, authenticated and delivered.

                  The Notes are subject to redemption upon not less than 30 nor
more than 60 days' notice by mail, at any time on or after August 15, 2004, as a
whole or in part, at the election of the Company, at a Redemption Price which,
if during the twelve month period beginning August 15, 2004 is equal to 106.500%
of the principal amount of this Note; if during the twelve month period
beginning August 15, 2005 is equal to 104.875% of the principal amount of this

Notes, or one or more Predecessor Notes, of record at the close of business on
the relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

                  At any time prior to August 15, 2002, the Company may on one

Redemption Price of 113% of the principal amount thereof, plus accrued and
unpaid interest to the Redemption Date, with the Net Cash Proceeds of one or
more Equity Offerings; PROVIDED THAT:

         (a)      at least 75% of the aggregate principal amount of Notes

Sale Offer or Change of Control Offer of this Note in part only, a new Note or
Notes for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

Holder of this Note shall be conclusive and binding upon such Holder and upon
all future Holders of this Note and of any Note issued upon the registration of

Indenture and subject to certain limitations therein set forth, Notes are
exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

                  No service charge will be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

principal hereof or

                                      A-12

such liability, acknowledges and consents to the transactions described under

set forth in Article Fourteen of the Indenture and reference is hereby made to
such Indenture for the precise terms of this Subsidiary Guarantee and other

as such, past, present or future of each Guarantor shall have any liability by
reason of his or its status as such stockholder, officer, director, employee or
incorporator for any obligations of any Guarantor under the Notes, the Indenture
or its Subsidiary Guarantee or for any claim based on, in respect of, or by
reason of, such obligations or their creation.
