Delaware corporation (as defined in Section 1.01 hereof, the "Company"), and
U.S. Bank Trust National Association, as trustee (as defined in Section 1.01
hereof, the "Trustee").

     The Company and the Trustee agree as follows for the benefit of each other
and for the equal and ratable benefit of the Holders (as defined) of the    %
Senior Notes due 2013 (the "Notes"):

                                   ARTICLE 1.
                          DEFINITIONS AND INCORPORATION
                                  BY REFERENCE

Section 1.01 Definitions.

     "Acquired Debt" means, with respect to any specified Person:

          (1) Indebtedness of any other Person existing at the time such other
     Person is merged with or into or became a Subsidiary of such specified
     Person, whether or not such Indebtedness is incurred in connection with, or
     in contemplation of, such other Person merging with or into, or becoming a
     Subsidiary of, such specified Person; and

          (2) Indebtedness secured by a Lien encumbering any asset acquired by
     such specified Person,

but excluding Indebtedness of such other Person that is extinguished, retired,
redeemed or repaid concurrently with such other Person becoming a Restricted
Subsidiary of, or at the time it is merged into or consolidates with, such
specified Person.

     "Additional Notes" means additional notes (other than the Initial Notes)
issued from time to time under this Indenture in accordance with Sections 2.02,
4.09 and 9.01 hereof, as part of the same series as the Initial Notes and
ranking equally with the Initial Notes in all respects (or in all respects other
than the payment of interest accruing prior to the issue date of such Additional
Notes).

     "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity of the

     "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control,"
as used with respect to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management or
policies of such Person, whether through the ownership of voting securities, by
agreement or otherwise; provided that beneficial ownership of 10% or more of the
Voting Stock of a Person shall be deemed to be control. For purposes of this
definition, the terms "controlling," "controlled by" and "under common control
with" have correlative meanings. Notwithstanding the foregoing, no Person (other
than the Company or any Subsidiary of the Company) in whom a Receivables
Subsidiary makes an Investment in connection with a Receivables Program shall be
deemed to be an Affiliate of the Company or any of its Subsidiaries solely by
reason of such Investment.

     "Agent" means any Registrar, co-registrar, Paying Agent or additional

     rights; provided that the sale, conveyance or other disposition of all or
     substantially all of the assets of the Company and its Restricted
     Subsidiaries taken as a whole shall be governed by the provisions of
     Section 5.01 hereof and, if applicable, the provisions of Section 4.14
     hereof and not by the provisions of Section 4.10 hereof; and

          (2) the issuance of Equity Interests by any of the Company's
     Restricted Subsidiaries to any Person other than to the Company or another
     Restricted Subsidiary.

          Notwithstanding the preceding, none of the following items shall be
     deemed to be an Asset Sale:

          (1) any single transaction or series of related transactions that
     involves Equity Interests or assets having a fair market value of less than
     $35 million;

          (2) a transfer of assets between or among the Company and one or more

     Restricted Subsidiary in connection with such transaction);

          (3) the sale or lease of inventory or accounts receivable in the
     ordinary course of business;

          (4) any sale or other disposition of Receivables and Related Assets
     pursuant to or in connection with a Receivables Program;

          (6) any sale or disposition deemed to occur in connection with (a)
     creating or granting any Permitted Lien or enforcing a Permitted Lien by

<PAGE>

rate of ____% per annum, from __________ or from the most recent Interest

The City of New York maintained for such purpose and at any other office or
agency maintained by the Company for such purpose; provided that at the option
of the Company payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Register.

     The Notes shall be redeemable as provided in Article 3 hereof.

Section 2.03  Execution, Authentication, Delivery and Dating.

     The Notes shall be executed on behalf of the Company by its Chairman of the
Board, its Vice Chairman of the Board, its President or one of its Vice
Presidents, attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signatures of individuals who were at
any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and
delivery of such Notes; and the Trustee in accordance with such Company Order
shall authenticate and deliver such Notes as in this Indenture provided and not
otherwise.

     Each Note shall be dated the date of its authentication.

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

     In case the Company, pursuant to Article 5, shall, in one or more related
transactions, be consolidated or merged with or into any other Person or shall
sell, assign, transfer, convey or otherwise dispose of all or substantially all
the properties or assets of the Company and its Restricted Subsidiaries taken as
a whole to any Person, and the successor Person resulting from such
consolidation or surviving such merger, or into which the Company shall have
been merged, or the successor Person which shall have participated in the sale,
assignment, transfer, conveyance or other disposition as aforesaid, shall have
assumed all of the obligations of the Company under the Notes and this Indenture
pursuant to agreements reasonably satisfactory to the Trustee pursuant to
Article 5, any of the Notes authenticated or delivered prior to such
consolidation, merger, sale, assignment, transfer, conveyance or other
disposition may, from time to time, at the request of the successor Person, be
exchanged for other Notes executed in the name of the successor Person with such
changes in phraseology and form as may be appropriate, but otherwise in
substance of like tenor as the Notes surrendered for such exchange and of like
principal amount; and the Trustee, upon the request of the successor Person,
shall authenticate and deliver Notes as specified in such

                                       24

<PAGE>

request for the purpose of such exchange. If Securities shall at any time be
authenticated and delivered in any new name of a successor Person pursuant to
this Section 2.03 in exchange or substitution for or upon registration of
transfer of any Notes, such successor Person, at the option of the Holders but
without expense to them, shall provide for the exchange of all Notes at the time
Outstanding for Notes authenticated and delivered in such new name.

Section 2.04  Temporary Notes.

     Pending the preparation of definitive Notes, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Notes
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Notes may determine, as evidenced by their execution of such
Notes.

     If temporary Notes are issued, the Company will cause definitive Notes to
be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at any office or agency of the Company
designated pursuant to Section 4.02 hereof, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Notes the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Notes of authorized denominations. Until so
exchanged the temporary Notes shall in all respects be entitled to the same
benefits under this Indenture as definitive Notes.

Section 2.05  Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 4.02 hereof being herein
sometimes collectively referred to as the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. The Trustee is hereby appointed
"Registrar" for the purpose of registering Notes and transfers of Notes as
herein provided.

     Upon surrender for registration of transfer of any Note at an office or
agency of the Company designated pursuant to Section 4.02 hereof for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Notes of any authorized denominations and of a like aggregate principal
amount. At the option of the Holder, Notes may be exchanged for other Notes of
any authorized denominations and of a like aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any
Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes which the Holder making the
exchange is entitled to receive.

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

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

                                       25

<PAGE>

     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 Notes, other than exchanges
pursuant to Section 2.04, 3.06, 3.08, 4.14 or 9.05 hereof 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 3.02 hereof 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.

     The provisions of clauses (a), (b), (c), (d), (e) and (f) below shall apply
only to Global Notes:

     (a) Each Global Note authenticated under this Indenture shall be registered
in the name of the Depositary or a nominee thereof and delivered to such
Depositary or a nominee thereof or custodian therefor, and each such Global Note
shall constitute a single Note for all purposes of this Indenture. Any Global
Note may be represented by more than one certificate. The aggregate amount of
each Global Note may be increased or decreased by adjustments made on the
records of the Trustee, as provided in this Indenture.

     (b) Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any Global Note held on
their behalf by the Depositary, or the Trustee as its custodian, or under such
Global Note, and the Depositary may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner of such Global
Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or shall impair, as between the
Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Note.

     (c) Notwithstanding any other provision in this Indenture, no Global Note
may be exchanged in whole or in part for a Note registered, and no transfer of a
Global Note in whole or in part may be registered, in the name of any Person
other than the Depositary for such Global Note or a nominee thereof unless (A)
such Depositary (i) has notified the Company that it is unwilling or unable to
continue as Depositary for such Global Note or (ii) has ceased to be a clearing
agency registered under the Exchange Act, (B) the Company, at its option,
executes and delivers to the Trustee a Company Order stating that it elects to
cause the issuance of the Notes registered in the names of the Holders thereof
and that all Global Notes shall be exchanged in whole for Notes that are not
Global Notes (in which case such exchange shall be effected by the Trustee), or
(C) there shall have occurred and be continuing a Default or an Event of
Default.

     (d) Subject to clause (b) above, any exchange of a Global Note for other
Notes may be made in whole or in part, and all Notes issued in exchange for a
Global Note or any portion thereof shall be registered in such names as the
Depositary shall direct.

     (e) Every Note authenticated and delivered upon registration of transfer
of, or in exchange for or in lieu of, a Global Note or any portion thereof,
whether pursuant to this Section 2.05 or Section 2.06, 3.06, 3.08, 4.14 or 9.05
hereof or otherwise, shall be authenticated and delivered in the form of, and
shall be, a Global Note, unless such Note is registered in the name of a Person
other than the Depositary for such Global Note or a nominee thereof.

                                       26

<PAGE>

     (f) Each Global Note will bear a Global Note Legend in substantially the
following form:

THIS SECURITY IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREINAFTER
REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF.
THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A NOTE REGISTERED,
AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE
NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN
THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

Section 2.06  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 protected purchaser, the
Company shall execute and 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 2.06, the Company may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected
therewith.

     Every new Note issued pursuant to this Section 2.06 in lieu of any
destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the 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 2.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Note.

Section 2.07  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 for such interest. 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

                                       27

<PAGE>

     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 (the "Special Payment
     Date"), and at the same time the Company shall deposit with the Trustee an
     amount of money equal to the aggregate amount proposed to be paid in
     respect of such Defaulted Interest or shall make arrangements satisfactory
     to the Trustee for such deposit prior to the Special Payment Date, 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 Special Payment Date 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 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 2.07, each Note delivered under this
     Indenture upon registration of transfer of or in exchange for or in lieu of
     any other Note shall carry the rights to interest accrued and unpaid, and
     to accrue, which were carried by such other Note.

     Notwithstanding anything to the contrary contained in this Indenture, the
Company may, to the extent required to do so by law, deduct or withhold income
or other similar taxes imposed by the United States of America from principal or
interest payments under this Indenture.

Section 2.08  Persons Deemed Owners.

     Prior to due presentment of a Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Note is registered as the owner of such Note for the
purpose of receiving payment of principal of (and premium, if any) and (subject
to Section 2.07 hereof) interest on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

Section 2.09  Cancellation.

     All Notes surrendered for payment, redemption, registration of transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled 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 cancelled by the
Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes
cancelled as provided in this Section 2.09, except as expressly permitted by
this Indenture. All cancelled Notes held by the Trustee shall be destroyed and
certification of their destruction delivered to the Company, unless by a Company
Order received by the

                                       28

<PAGE>

Trustee prior to such destruction, the Company shall direct that the cancelled
Notes be returned to it. The Trustee shall provide the Company a list of all
Notes that have been cancelled from time to time as requested by the Company.

Section 2.10  Computation of Interest.

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

Section 2.11  Paying Agent to Hold Money in Trust.

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

Section 2.12  CUSIP Numbers.

     The Company in issuing the Notes may use "CUSIP" numbers (if then generally
in use), and the Trustee, on behalf of the Company, shall use such CUSIP numbers
in notices of redemption or exchange as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of redemption or exchange and that reliance may be placed only on the
other identification numbers printed on the Notes; and provided further,
however, that failure to use CUSIP numbers in any notice of redemption or
exchange shall not affect the validity or sufficiency of such notice.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

Section 3.01  Notices to Trustee.

     If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30
days but not more than 60 days before a redemption date a certificate setting
forth:

          (1)  the clause of this Indenture pursuant to which the redemption
     shall occur;

          (2)  the redemption date;

          (3)  the principal amount of Notes to be redeemed; and

          (4)  the redemption price.

                                       29

<PAGE>

Section 3.02  Selection of Notes to Be Redeemed.

     If less than all of the Notes are to be redeemed, the Trustee will select
Notes for redemption as follows:

          (1)  if the Notes are listed on any national securities exchange, in
     compliance with the requirements of the principal national securities
     exchange on which the Notes are listed; or

          (2)  if the Notes are not listed on any national securities exchange,
     on a pro rata basis, by lot or by such method as the Trustee shall deem
     fair and reasonable.

     In the event of partial redemption by lot, the particular Notes to be
redeemed will be selected not less than 30 days nor more than 60 days prior to
the redemption date by the Trustee from the Outstanding Notes not previously
called for redemption.

     The Trustee will promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. No Notes of $1,000 or
less may be redeemed in part.

Section 3.03  Notice of Redemption.

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Notes are to be redeemed at its registered
address.

     The notice shall identify the Notes to be redeemed and shall state:

          (1)  the redemption date;

          (2)  the redemption price;

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

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

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

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

     At the Company's request (which may be revoked at any time prior to the
time at which the Trustee shall have given such notice to the Holders), the
Trustee will give the notice of redemption in the Company's name and at its
expense; provided that the Company shall have delivered to the Trustee, at least
45 days prior to the redemption date (unless the Trustee is satisfied with a
shorter period), a Company Order requesting that the Trustee give such notice
and setting forth the information to be stated in such notice as provided in the
preceding paragraph.

                                       30

<PAGE>

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

Section 3.04  Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Notes called for redemption become irrevocably due and payable on the redemption
date at the redemption price. A notice of redemption may not be conditional.
Such notice if mailed in the manner herein provided shall be conclusively
presumed to have been given, whether or not the Holder receives such notice.

Section 3.05  Deposit of Redemption Price.

     On or one Business Day prior to the redemption date, the Company shall
deposit with the Trustee or with the Paying Agent an amount of money sufficient
to pay the redemption price of and accrued interest, if any, on all Notes to be
redeemed on that date. All money, if any, earned on funds held in trust by the
Trustee or any Paying Agent shall be remitted to the Company. In addition, the
Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest, if any,
on, all Notes to be redeemed.

     If the Company complies with the provisions of the preceding paragraph, on
and after the redemption date, interest will cease to accrue on the Notes or the
portions of Notes called for redemption. If any Note called for redemption is
not so paid upon surrender for redemption because of the failure of the Company
to comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption date until such principal is paid, and to the
extent lawful on any interest not paid on such unpaid principal, in each case at
the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06  Notes Redeemed in Part.

     Upon surrender of a Note that is redeemed in part, the Company will issue
and the Trustee will authenticate for the Holder at the expense of the Company a
new Note or Notes in authorized denominations equal in principal amount to the
unredeemed portion of the Note surrendered.

Section 3.07  Optional Redemption.

     The Company may at any time at its option redeem all or part of the Notes
upon not less than 30 days' nor more than 60 days' prior notice at a redemption
price equal to the greater of (1) 100% of the principal amount of the Notes
being redeemed and (2) as determined by the Quotation Agent, the sum of the
present values of 100% of the principal amount of the Notes being redeemed, plus
all scheduled payments of interest on such Notes to and including July , 2013
(but not including accrued and unpaid interest to the redemption date), in each
case discounted to the redemption date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
plus 50 basis points, together in each case with accrued and unpaid interest to
the applicable redemption date.

Section 3.08  Offer to Purchase by Application of Excess Proceeds.

     In the event that the Company is required to commence an offer to all
Holders to purchase Notes pursuant to Section 4.10 hereof (an "Asset Sale
Offer"), it shall follow the procedures specified below.

                                       31

<PAGE>

     The Asset Sale Offer shall be made to all Holders of Notes, and at the
Company's option, to all holders of other Indebtedness that is pari passu with,
or subordinate in right of payment to, the Notes. The Asset Sale Offer shall
remain open for a period of at least 20 Business Days, and not more than 30
Business Days, following its commencement, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than three
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Company shall apply all Excess Proceeds (the "Offer Amount") to the purchase
of Notes and such other Indebtedness in the manner required by Section 4.10
hereof.

     Upon the commencement of an Asset Sale Offer, the Company will send, by
first class mail, a notice to each of the Holders, with a copy to the Trustee,
containing all instructions and materials necessary to enable such Holders to
tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the
terms of the Asset Sale Offer, will state:

          (1)  that the Asset Sale Offer is being made pursuant to this Section
     3.08 and Section 4.10 hereof and the length of time the Asset Sale Offer
     will remain open;

          (2)  the Offer Amount, the purchase price and the Purchase Date;

          (3)  that any Note not tendered or not accepted for payment will
     continue to accrue interest;

          (4)  that, unless the Company defaults in making such payment, any
     Note accepted for payment pursuant to the Asset Sale Offer will cease to
     accrue interest after the Purchase Date;

          (5)  that Holders electing to have a Note purchased pursuant to an
     Asset Sale Offer may elect to have Notes purchased in integral multiples of
     $1,000 only;

          (6)  that Holders electing to have a Note purchased pursuant to any
     Asset Sale Offer will be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" attached to the Note, in the
     form of Annex B thereto, completed, to the Company, a depositary, if
     appointed by the Company, or a Paying Agent at the address specified in the
     notice at least three Business Days before the Purchase Date;

          (7)  that Holders will be entitled to withdraw their election by
     delivery to the Company, the depositary or the Paying Agent, as the case
     may be, not later than the expiration of the Offer Period, a telegram,
     telex, facsimile transmission or letter setting forth the name of the
     Holder, the principal amount of the Note the Holder delivered for purchase
     and a statement that such Holder is withdrawing his election to have such
     Note purchased;

          (8)  that, if the aggregate principal amount of Notes and other
     Indebtedness (or accreted value, as applicable) surrendered by Holders
     exceeds the Offer Amount, the Excess Proceeds will be applied in the
     following way: (a) first, the Excess Proceeds will be applied to purchase
     the Notes and other pari passu Indebtedness tendered for purchase, on a pro
     rata basis (if the aggregate principal amount of such Notes and pari passu
     Indebtedness exceeds the amount of Excess Proceeds), and (b) second, if and
     to the extent any Excess Proceeds remain after the purchase of all of the
     Notes and other pari passu Indebtedness tendered for purchase, the
     remaining Excess Proceeds will be applied to purchase any subordinated
     Indebtedness tendered for purchase, on a pro rata basis (with such
     adjustments as may be deemed appropriate by the Company so that only Notes
     in denominations of $1,000, or integral multiples thereof, will be
     purchased); and

                                       32

<PAGE>

          (9) that Holders whose Notes were purchased only in part will be
     issued new Notes in authorized denominations equal in principal amount to
     the unpurchased portion of the Notes surrendered.

     On or before the Purchase Date, the Company shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes and other pari passu Indebtedness or portions thereof tendered
pursuant to the Asset Sale Offer, or if less than the Offer Amount of Notes and
other pari passu Indebtedness has been tendered, all Notes tendered, and shall
deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 3.08 and Section 4.10(c) hereof. The Company, the
depositary or the Paying Agent, as the case may be, shall promptly (but in any
case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by
such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Note or Notes in authorized denominations, and the Trustee,
upon written request from the Company will authenticate and mail or deliver such
new Note or Notes to such Holder, in a principal amount equal to any unpurchased
portion of the Note surrendered. The Trustee and the Paying Agent shall return
to the Company any cash that remains unclaimed, together with interest, if any,
thereon, held by them for the payment of the offer price. Any Note not so
accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company will publicly announce the results of the Asset Sale Offer
as soon as reasonably practicable on or after the Purchase Date.

Section 4.01  Payment of Notes.

     The Company shall pay or cause to be paid the principal of, and any premium
and interest on, the Notes on the dates and in the manner provided in the Notes.

immediately available funds and designated for and sufficient to pay all
principal, any premium and interest then due.

     The Company shall pay interest (including post-petition interest in any

presented for payment and surrendered for registration of transfer or for
exchange and where notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Company shall give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company fails to maintain any such required
office or agency or fails 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.

                                       33

     The Company may also from time to time designate one or more other offices
or agencies (in or outside of 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 that no such designation or rescission will
in any manner relieve the Company of its obligation to maintain an office or
agency in 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 4.03  Reports.

          (i)   no Default or Event of Default has occurred and is continuing;

          (ii)  the Company could incur at least $1.00 of additional
     Indebtedness pursuant Section 4.09(a) hereof; and

     all other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the date of this Indenture (excluding Restricted
     Payments permitted by clauses (2), (3), (6), (8) and (10) of Section
     4.07(b) hereof), is less than the sum, without duplication, of:

          Company's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of the amount of such deficit), plus

                (B) 100% of the aggregate net cash proceeds received by the

          common equity capital or from the issue or sale of Equity Interests of
          the Company (other than Disqualified Stock) or (ii) from the issue or
          sale of convertible or exchangeable Disqualified Stock or convertible
          or exchangeable debt securities of the Company upon conversion into or
          exchange for such Equity Interests (other than Equity Interests (or
          Disqualified Stock or debt securities) sold to a Subsidiary of the
          Company), plus

       incurred at the beginning of such four-quarter period.

       (c) For purposes of determining compliance with this Section 4.09:

             (1)  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 (16) of Section 4.09(b) hereof, or is entitled to
       be incurred pursuant to Section 4.09(a) hereof, the Company shall be
       permitted to classify all or a portion of such item of Indebtedness on
       the date of its incurrence, or, subject to Section 4.09(c)(2) below,
       later reclassify all or a portion of such item of Indebtedness, in any
       manner that complies with this Section 4.09;

             (2)  Indebtedness under Credit Facilities outstanding on the date
       of this Indenture shall be deemed to have been incurred on such date in
       reliance on the exception provided by Section 4.09(b)(1) hereof, and
       Indebtedness under a Receivables Program outstanding on the date of this
       Indenture shall be deemed to have been incurred on such date in reliance
       on the exception provided by Section 4.09(b)(12) hereof, and the Company
       shall not be permitted to reclassify any portion of such Indebtedness
       thereafter;

             (3)  the outstanding principal amount of any particular
       Indebtedness shall be counted only once and any obligations arising under
       any guarantee, Lien, letter of credit or similar instrument supporting
       such Indebtedness shall not be counted twice;

             (4)  the accrual of interest, the accretion or amortization of
       original issue discount, the payment of interest on any Indebtedness in
       the form of additional Indebtedness with the same terms, and the payment
       of dividends on Disqualified Stock in the form of additional shares of
       the same class of Disqualified Stock will not be deemed to be an
       incurrence of Indebtedness or an issuance of Disqualified Stock for
       purposes of this Section 4.09; provided, in each such case, that the
       amount thereof is included in Fixed Charges of the Company as accrued;

             (5)  the amount of Indebtedness issued at a price that is less than
       its principal amount will be equal to the amount of the liability in
       respect thereof determined in accordance with GAAP; and

             (6)  if Obligations in respect of letters of credit are incurred
       pursuant to any Credit Facility and are being treated as incurred
       pursuant to clause (1) of Section 4.09(b) hereof and the letters of
       credit relate to other Indebtedness, such other Indebtedness will be
       deemed not incurred to the extent of such Obligations.

       With respect to overdraft lines, the amount of any outstanding
Indebtedness shall be determined net of cash held for the benefit of the
relevant entity by the institution creating such overdraft.

                                       43

       (d)  After the occurrence of a Fall Away Event, the Company will not
permit any of its Restricted Subsidiaries (other than a Subsidiary Guarantor)
to, directly or indirectly, incur any Indebtedness (including Acquired Debt) or
to issue any shares of preferred stock other than Permitted Debt.

Section 4.10  Asset Sales.

       (a)  The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

              (1)  the Company (or the Restricted Subsidiary, as the case may
       be) receives consideration at the time of the Asset Sale at least equal
       to the fair market value, as determined in good faith by the Company's
       Board of Directors, of the assets or Equity Interests issued or sold or
       otherwise disposed of; and

              (2)  at least 75% of the consideration received in the Asset Sale
       by the Company or such Restricted Subsidiary is in the form of cash or
       Replacement Assets, or a combination of both. For purposes of this
       provision, each of the following will be deemed to be cash:

                   (A) any liabilities, as shown on the Company's most recent
              consolidated balance sheet, of the Company or any Restricted
              Subsidiary (other than contingent liabilities and liabilities that
              are by their terms subordinated to the Notes or Subsidiary
              Guarantees) that are assumed by the transferee of any such assets
              pursuant to an agreement that releases the Company or such
              Restricted Subsidiary from further liability;

                   (B) any securities, notes or other obligations received by
              the Company or any such Restricted Subsidiary from such transferee
              that are converted by the Company or such Restricted Subsidiary
              into cash, to the extent of the cash received in that conversion,
              within 180 days after receipt;

                   (C) Cash Equivalents; and

                   (D) any Designated Noncash Consideration received by the
              Company or any of its Restricted Subsidiaries in the Asset Sale.

       (b) Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company or any Restricted Subsidiary may apply such Net Proceeds:

              (1)  to repay Indebtedness and other Obligations under any Credit
       Facility that is not expressly subordinated in right of payment to the
       Notes or other senior Indebtedness;

              (2)  to repay (or repurchase) any secured Indebtedness;

              (3)  to repay (or repurchase) any Indebtedness of such Restricted
       Subsidiary other than a Subsidiary Guarantor (except to the extent that
       such Indebtedness is pari passu with the Notes or the Subsidiary
       Guarantee given by such Subsidiary Guarantor);

              (4)  to repay (or repurchase) any Indebtedness with a final Stated
       Maturity that is prior to the final Stated Maturity of the Notes;

              (5)  to acquire a majority of the Voting Stock of another Person
       or all or substantially all of the assets of one or more other Persons or
       units, divisions or other operating portions

                                       44

<PAGE>

       thereof (including by means of a merger, consolidation or other business
       combination permitted under this Indenture);

              (6)  to make one or more capital expenditures;

              (7)  to acquire other noncurrent assets that are useful in the
       business of the Company or any of its Restricted Subsidiaries; or

              (8)  to acquire Capital Stock consisting of a minority interest in
       any Person that at such time is a Restricted Subsidiary of the Company.

       Pending the final application of any such Net Proceeds, the Company and
any Restricted Subsidiary may temporarily reduce revolving credit borrowings or
otherwise invest the Net Proceeds in any manner that is not prohibited by this
Indenture.

       (c) Any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.10(b) hereof shall constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $100 million, the Company shall,
within 30 days, make an Asset Sale Offer to all Holders of Notes; and, at the
Company's option, to all holders of other Indebtedness that is pari passu with,
or subordinate in right of payment to, the Notes, in each case in accordance
with Section 3.08 hereof, to purchase the maximum principal amount of Notes and
such other Indebtedness that may be purchased out of the Excess Proceeds. The
offer price in any Asset Sale Offer will be equal to 100% of the principal
amount of the Notes or any other Indebtedness being repurchased plus accrued and
unpaid interest, if any, to the date of purchase (or 100% of the accreted value
thereof, in the case of other Indebtedness that was initially offered and sold
at a discount), and will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use those Excess Proceeds
for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and other Indebtedness (or accreted value, as
applicable) tendered into such Asset Sale offer exceeds the amount of Excess
Proceeds, the Excess Proceeds will be applied in the following way: (a) first,
the Excess Proceeds will be applied to purchase the Notes and other pari passu
Indebtedness tendered for purchase, on a pro rata basis (if the aggregate
principal amount of such Notes and pari passu Indebtedness exceeds the amount of
Excess Proceeds), and (b) second, if and to the extent any Excess Proceeds
remain after the purchase of all of the Notes and other pari passu Indebtedness
tendered for purchase, the remaining Excess Proceeds will be applied to purchase
any subordinated Indebtedness tendered for purchase, on a pro rata basis. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.

       The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other federal or state securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of Section 3.08 hereof or this Section 4.10, the Company shall comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under those provisions of this Indenture by virtue
of such conflict.

Section 4.11  Transactions with Affiliates.

       (a) 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 from, or enter into or make or amend any transaction, contract,
agreement,

                                       45

<PAGE>

understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (each, an "Affiliate Transaction"), unless:

             (1)  the Affiliate Transaction is on terms, when taken as a whole,
       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 with an
       unrelated Person; and

             (2)  the Company delivers to the Trustee with respect to any
       Affiliate Transaction or series of related Affiliate Transactions
       involving aggregate consideration (a) not in excess of $10 million, an
       officers' certificate certifying that such Affiliate Transaction complies
       with this Section 4.11(a) or (b) in excess of $10 million, either (i) an
       Officers' Certificate certifying that such Affiliate Transaction has been
       approved by a majority of the disinterested members of the Board of
       Directors of the Company or (ii) an opinion as to the fairness to the
       Company of such Affiliate Transaction from a financial point of view
       issued by an accounting, appraisal or investment banking firm of national
       standing.

       (b) The following items will not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

             (1)  any employment, compensation, benefit or indemnification
       agreement or arrangement (and any payments or other transactions pursuant
       thereto) entered into by the Company or any of its Restricted
       Subsidiaries in the ordinary course of business with an officer, employee
       or director and any transactions pursuant to stock option plans, stock
       ownership plans and employee benefit plans or arrangements;

             (2)  transactions between or among the Company and/or its
       Restricted Subsidiaries (including any Person that becomes a Restricted
       Subsidiary of the Company as a result of any such transaction);

             (3)  transactions with a Person that is an Affiliate of the Company
       solely because the Company owns an Equity Interest in, or controls, such
       Person;

             (4)  payment of reasonable fees to directors who are not otherwise
       employees of the Company;

             (5)  sales of Equity Interests (other than Disqualified Stock) to
       Affiliates of the Company;

             (6)  Restricted Payments that are permitted by Section 4.07 hereof;

             (7)  loans or advances to employees or consultants in the ordinary
       course of business of the Company or its Restricted Subsidiaries;

             (8)  transactions between a Receivables Subsidiary and any Person
       in which the Receivables Subsidiary has an Investment or any other
       transactions in connection with a Receivables Program of the Company or a
       Restricted Subsidiary of the Company;

             (9)  transactions pursuant to or contemplated by any agreement of
       the Company or any Restricted Subsidiary of the Company entered into on
       or prior to the date of this Indenture or any amendment thereto or any
       replacement agreement so long as any such amendment or

                                       46

<PAGE>

       replacement agreement, taken as a whole, is not materially more
       disadvantageous to the Holders than the original agreement as in effect
       on the date of this Indenture; and

              (10) the entering into of any agreement with an Affiliate filed as
       an exhibit to the Company's registration statement on Form S-1 (No.
       333-86404), the subsequent amendment from time to time of any such
       agreement in a manner not materially less favorable, taken as a whole, to
       the Company and its Restricted Subsidiaries or the performance by the
       Company or any of its Restricted Subsidiaries of any such agreement in
       accordance with its terms, as initially entered into or as so amended.

Section 4.12  Liens.

       (a) Prior to a Fall Away Event, the Company shall not, and shall not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or permit to exist any Lien securing Indebtedness, Attributable
Debt or trade payables (other than Permitted Liens) on any asset now owned or
hereafter acquired, unless all payments due under this Indenture and the Notes
are secured on an equal and ratable basis with (or prior to) the Obligations so
secured until such time as such obligations are no longer secured by a Lien.

       (b) After a Fall Away Event, the Company shall not, and shall not permit
any Restricted Subsidiary to, create, incur, assume or permit to exist any Lien
(other than Fall Away Permitted Liens) upon (1) any Principal Property of the
Company or any Restricted Subsidiary, (2) any Equity Interest of a Restricted
Subsidiary or (3) any Indebtedness of a Restricted Subsidiary owed to the
Company or another Restricted Subsidiary, unless, in each case (1), (2) and (3),
the Outstanding Notes shall be secured equally and ratably with (or prior to)
all Indebtedness secured by such Lien.

       (c) Notwithstanding anything to the contrary in this Section 4.12, after
a Fall Away Event, the Company and its Restricted Subsidiaries shall be
permitted to create or assume Liens without complying with Section 4.12(b)
above, provided that the aggregate amount of all Indebtedness of the Company and
its Restricted Subsidiaries that is secured by these Liens (other than (1)
Indebtedness secured solely by Fall Away Permitted Liens, (2) Indebtedness that
is secured equally and ratably with (or on a basis subordinated to) the Notes
and (3) the Notes) plus the aggregate amount of all Attributable Debt of the
Company and its Restricted Subsidiaries with respect to all Sale and Leaseback
Transactions outstanding at such time (other than Sale and Leaseback
Transactions permitted by Section 4.15(b) hereof), would not exceed 10% of the
Consolidated Net Tangible Assets of the Company.

Section 4.13  Corporate Existence.

       Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect:

              (1)  its corporate existence, and the corporate, partnership or
       other existence of each of its Restricted Subsidiaries, in accordance
       with the respective organizational documents (as the same may be amended
       from time to time) of the Company or any such Restricted Subsidiary; and

              (2)  the rights (charter and statutory), licenses and franchises
       of the Company and its Restricted Subsidiaries; provided that the Company
       shall not be required to preserve any such right, license or franchise,
       or the corporate, partnership or other existence of any of its Restricted
       Subsidiaries, if the Board of Directors shall determine that the
       preservation thereof is no longer desirable in the conduct of the
       business of the Company and its Restricted Subsidiaries, taken as a
       whole, and that the loss thereof is not adverse in any material respect
       to the Holders of the Notes.

Section 4.14   Offer to Repurchase Upon Change of Control.

       (a) Upon the occurrence of a Change of Control Event, unless the Company
has exercised its right to redeem the Notes as provided in Section 3.07 hereof,
the Company will make an offer (a "Change of Control Offer") to each Holder to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of
each Holder's Notes at a repurchase price in cash equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest, if any, on the Notes
repurchased to the date of purchase (the "Change of Control Payment"). Within 30
days following any Change of Control Event or, at the Company's option, prior to
any Change of Control but after the public announcement thereof, the Company
shall mail a notice to each Holder describing the transaction or transactions
that constitute or may constitute the Change of Control Event and stating:

               (1)   if mailed prior to the date of consummation of the Change
       of Control, that the offer to purchase is conditioned on the Change of
       Control Event occurring on or prior to the payment date specified in the
       notice;

               (2)   that the Change of Control Offer is being made pursuant to
       this Section 4.14 and that all Notes tendered will be accepted for
       payment;

               (3)   the purchase price and the purchase date, which shall be no
       earlier than 30 days and no later than 60 days from the date such notice
       is mailed (the "Change of Control Payment Date");

               (4)   that any Note not tendered will continue to accrue
       interest;

               (5)   that, unless the Company defaults in the payment of the
       Change of Control Payment, all Notes accepted for payment pursuant to the
       Change of Control Offer will cease to accrue interest after the Change of
       Control Payment Date;

               (6)   that Holders electing to have any Notes purchased pursuant
       to a Change of Control Offer will be required to surrender the Notes,
       with the form entitled "Option of Holder to Elect Purchase" attached to
       the Notes completed, to the Paying Agent at the address specified in the
       notice prior to the close of business on the third Business Day preceding
       the Change of Control Payment Date;

               (7)   that Holders will be entitled to withdraw their election if
       they deliver to the Paying Agent, not later than the close of business on
       the second Business Day preceding the Change of Control Payment Date, a
       telegram, telex, facsimile transmission or letter setting forth the name
       of the Holder, the principal amount of Notes delivered for purchase, and
       a statement that such Holder is withdrawing his election to have the
       Notes purchased; and

               (8)   that Holders whose Notes are being purchased only in part
       will be issued new Notes equal in aggregate principal amount to the
       unpurchased portion of the Notes surrendered, which unpurchased portion
       must be equal to $1,000 in principal amount or an integral multiple
       thereof.

       The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other federal and state securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change in Control Event. To
the extent that the provisions of any securities laws or regulations conflict
with the provisions of this Section 4.14, the Company shall comply with the
applicable securities laws and regulations and will not

                                       48

<PAGE>

be deemed to have breached its obligations under this Section 4.14 and all other
provisions of this Indenture applicable to a Change of Control Offer made by the
Company by virtue of such conflict.

     (b) On the Change of Control Payment Date, the Company shall, to the extent
lawful:

          (1)  accept for payment all Notes or portions thereof properly
     tendered pursuant to the Change of Control Offer;

          (2)  deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Notes or portions of Notes properly
     tendered; and

          (3)  deliver or cause to be delivered to the Trustee the Notes
     properly accepted together with an Officers' Certificate stating the
     aggregate principal amount of Notes or portions of Notes being purchased by
     the Company.

     The Paying Agent shall promptly deliver to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and deliver to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided
that each new Note will be in a principal amount of $1,000 or an integral
multiple thereof. The Company shall publicly announce the results of the Change
of Control Offer on or as soon as practicable after the Change of Control Event
Payment Date.

     (c) Prior to a Fall Away Event, the provisions described above in this
Section 4.14 that require the Company to make a Change of Control Offer
following a Change of Control Event will be applicable whether or not any other
provisions of this Indenture are applicable.

     (d) Notwithstanding anything to the contrary in this Section 4.14, the
Company will not be required to make a Change of Control Offer upon a Change of
Control Event if a third party makes the Change of Control Offer in the manner,
at the times and otherwise in compliance with the requirements set forth in this
Section 4.14 and all other provisions of this Indenture applicable to a Change
of Control Offer made by the Company and such third party purchases all Notes
validly tendered and not withdrawn under the Change of Control Offer.

Section 4.15  Limitation on Sale and Leaseback Transactions.

     (a) Prior to a Fall Away Event, 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 that Restricted Subsidiary, as applicable, could
     have (a) incurred Indebtedness in an amount equal to the Attributable Debt
     relating to such Sale and Leaseback Transaction under Section 4.09(a)
     hereof and (b) incurred a Lien to secure such Indebtedness pursuant to
     Section 4.12(a) hereof;

          (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 or, if the such fair market value is
     less than or equal to $10 million, the chief executive, chief financial or
     chief accounting officer, the controller or the treasurer of the Company,
     and set forth in an Officers' Certificate delivered to the Trustee, of the
     property that is the subject of that Sale and Leaseback Transaction; and

                                       49

<PAGE>

          (3) the transfer of assets in that Sale and Leaseback Transaction is
     permitted by, and the Company or such Restricted Subsidiary applies the
     proceeds of such transaction in compliance with, Section 4.10 hereof.

     (b) After a Fall Away Event, the Company shall not, and shall not permit
any of its Restricted Subsidiaries to, enter into any Sale and Leaseback
Transaction involving any Principal Property, except for any Sale and Leaseback
Transaction involving a lease not exceeding three years, unless:

          (1)  the Company or that Restricted Subsidiary, as applicable, would
     be entitled to incur Indebtedness secured by a Lien on that Principal
     Property without equally and ratably securing the Notes;

          (2)  an amount equal to the Attributable Debt of the Sale and
     Leaseback Transaction is applied within 180 days to:

               (A)  the voluntary retirement of any of Indebtedness of the
          Company or any Restricted Subsidiary maturing more than one year after
          the date incurred, and which is senior to or pari passu in right of
          payment with the Notes; or

               (B)  the purchase of other property that will constitute
          Principal Property having a value at least equal to the net proceeds
          of the sale; or

          (3)  the Company or that Restricted Subsidiary, as applicable,
     delivers to the Trustee for cancellation Notes in an aggregate principal
     amount at least equal to the net proceeds of the sale.

     (c) Notwithstanding anything to the contrary in this Section 4.15, after a
Fall Away Event, the Company may enter into Sale and Leaseback Transactions that
would not otherwise be permitted under the limitations described in Section
4.15(b) above, provided that the sum of the aggregate amount of all Indebtedness
of the Company and its Restricted Subsidiaries that is secured by Liens on any
properties or assets of the Company and any Restricted Subsidiaries (other than
(1) Indebtedness secured solely by Fall Away Permitted Liens, (2) Indebtedness
that is secured equally and ratably with (or on a basis subordinated to) the
Notes and (3) the Notes) and the aggregate amount of all Attributable Debt of
the Company and its Restricted Subsidiaries with respect to all Sale and
Leaseback Transactions outstanding at such time (other than Sale and Leaseback
Transactions permitted by Section 4.15(b) above) would not exceed 10% of the
Consolidated Net Tangible Assets of the Company.

Section 4.16  Payments for Consent.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder of Notes 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 of the Notes 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 4.17  Designation of Restricted and Unrestricted Subsidiaries.

     The Board of Directors of the Company may designate any Restricted
Subsidiary of the Company as an Unrestricted Subsidiary if no Default has
occurred and is continuing at the time of such designation and if that
designation would not cause a Default. If a Restricted Subsidiary of the Company
is designated

                                       50

<PAGE>

as an Unrestricted Subsidiary, the aggregate fair market value of all
outstanding Investments owned by the Company and its Restricted Subsidiaries in
the Subsidiary properly designated will be deemed to be an Investment made as of
the time of the designation and will reduce the amount available for Restricted
Payments under Section 4.07(a) hereof or Permitted Investments, as determined by
the Company. That designation will only be permitted if the Investment would be
permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. In addition, no such designation may
be made unless the proposed Unrestricted Subsidiary does not beneficially own
any Equity Interests in any Restricted Subsidiary that is not simultaneously
subject to designation as 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 4.18  Changes in Covenants if Notes Rated Investment Grade.

     If on any date following the date of this Indenture the Notes have an
Investment Grade Rating from both of the Rating Agencies and no Default or Event
of Default has occurred and is continuing (a "Fall Away Event"), then, beginning
on that day and continuing at all times thereafter regardless of any subsequent
changes in the rating of the Notes, Sections 3.08, 4.07, 4.08, 4.09(a) through
(c), 4.10, 4.11, 4.12(a), 4.14, 4.15(a), 4.16 and 5.01(a)(4) hereof shall no
longer be applicable to the Notes.

Section 4.19  Subsidiary Guarantees.

     The Company may cause any of its Restricted Subsidiaries to guarantee the
Notes and thereby to become a Subsidiary Guarantor by entering into a
supplemental indenture substantially in the form of Exhibit C hereto. If the
Company causes any of its Restricted Subsidiaries to become a Subsidiary
Guarantor, it shall cause the Subsidiary Guarantee of such Subsidiary Guarantor
to remain in full force and effect until released in accordance with Section
10.05 hereof and the supplemental indenture pursuant to which such Restricted
Subsidiary became a Subsidiary Guarantor.

Section 5.01  Merger, Consolidation, or Sale of Assets.

     (a) The Company shall not, directly or indirectly: (i) consolidate or merge
with or into another Person (whether or not the Company is the surviving
corporation); or (ii) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of the properties or assets of the Company and its
Restricted Subsidiaries taken as a whole, in one or more related transactions,
to another Person; unless:

          (1)  either:

               (A) the Company is the surviving corporation; or

               (B) the Person formed by or surviving any such consolidation or
          merger (if other than the Company) or to which such sale, assignment,
          transfer, conveyance or other disposition has been made is a Person
          organized or existing under the laws of the United States, any state
          of the United States or the District of Columbia;

          (2)  the Person formed by or surviving any such consolidation or
     merger (if other than the Company) or the Person to which such sale,

<PAGE>

     disposition shall have been made assumes all the obligations of the Company
     under the Notes and this Indenture pursuant to agreements reasonably
     satisfactory to the Trustee;

          (3)  immediately after such transaction, no Default or Event of
     Default exists; and

          (4)  the Company or the Person formed by or surviving any such
     consolidation or merger (if other than the Company), or to which such sale,
     assignment, transfer, conveyance or other disposition has been made would,
     on the date of such transaction after giving pro forma effect thereto and
     any related financing transactions as if the same had occurred at the
     beginning of the applicable four-quarter period, be permitted to incur at
     least $1.00 of additional Indebtedness pursuant to Section 4.09(a) hereof.

     (b) Notwithstanding Section 5.01(a)(4) hereof, if (1) any Restricted
Subsidiary consolidates with, merges into or transfers all or part of its
properties and assets to the Company or to any other Restricted Subsidiary of
the Company, (2) the Company merges with a Wholly Owned Subsidiary of the
Company with no liabilities other than de minimis liabilities or (3) the Company
merges with an Affiliate incorporated in the United States primarily for the
purpose of reincorporating the Company in another jurisdiction, then no
violation of this Section 5.01 shall be deemed to have occurred, as long as the
requirements of clauses (1), (2) and (3) of Section 5.01(a) are satisfied.

     (c) The Company shall not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related

or any Subsidiary Guarantor that is a Wholly Owned Subsidiary of the Company by
any of the Company's Restricted Subsidiaries.

Section 5.02  Successor Corporation Substituted.

     Upon any consolidation or merger, or any sale, assignment, transfer, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company in a transaction that is subject to, and that complies with the
provisions of, Section 5.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided that the
predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale of all of
the Company's assets in a transaction that is subject to, and that complies with
the provisions of, Section 5.01 hereof.

Section 6.01  Events of Default.

     (a) Each of the following is an "Event of Default":

     with the provisions of Section 4.14 or 5.01 hereof;

          (4)  the Company or any of its Restricted Subsidiaries fails to

     Notes then Outstanding;

          (5)  a default occurs under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any Indebtedness for money borrowed by the Company or any of its
     Significant Subsidiaries (or the payment of which is Guaranteed by the
     Company or any of its Significant Subsidiaries), whether such Indebtedness
     or Guarantee now exists, or is created after the date of this Indenture, if
     that default:

               (A) is caused by a failure to pay principal of, or any premium or
          interest on, such Indebtedness after the expiration of the grace
          period provided in such Indebtedness on the date of such default (a
          "Payment Default"); or

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

     and, in each case, the principal amount of any such Indebtedness, together
     with the principal amount of any other such Indebtedness under which there
     has been a Payment Default or the maturity of which has been so
     accelerated, aggregates $50 million or more and has not been discharged in
     full or such acceleration rescinded or annulled within 20 days of such
     Payment Default or acceleration;

          (6)  failure by the Company or any of its Significant Subsidiaries to
     pay final, non-appealable judgments aggregating in excess of $50 million,
     which judgments are not paid, discharged or stayed for a period of 60 days;

          (7)  the Company or any of its Significant Subsidiaries or Restricted
     Subsidiaries that, if taken together, would constitute a Significant
     Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

               (A) commences a voluntary case,

               (B) consents to the entry of an order for relief against it in an
          involuntary case,

               (C) consents to the appointment of a custodian of it or for all
          or substantially all of its property,

               (D) makes a general assignment for the benefit of its creditors,
          or

                                       53

<PAGE>

          (8)  a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (A) is for relief in an involuntary case against the Company or
          any of its Significant Subsidiaries or Restricted Subsidiaries that,
          if taken together, would constitute a Significant Subsidiary;

               (B) appoints a custodian of the Company or any of its Significant
          Subsidiaries or Restricted Subsidiaries that, if taken together, would
          constitute a Significant Subsidiary; or

               (C) orders the liquidation of the Company or any of its
          Significant Subsidiaries or Restricted Subsidiaries that, if taken
          together, would constitute a Significant Subsidiary;

     and the order or decree remains unstayed and in effect for 60 consecutive
     days.

     (b) Upon becoming aware of any Default or Event of Default, the Company
shall deliver to the Trustee a statement specifying such Default or Event of
Default.

Section 6.02  Acceleration.

     In the case of an Event of Default specified in clause (7) or (8) of
Section 6.01(a) hereof, all Outstanding Notes will become due and payable
immediately without further action or notice. If any other Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then Outstanding Notes may declare all the Notes to be
due and payable immediately. In the event of a declaration of acceleration of
the Notes because an Event of Default described in clause (5) of Section 6.01(a)
hereof has occurred and is continuing, the declaration of the acceleration of
the Notes shall be automatically annulled if prior to such declaration of
acceleration the event of default or payment default triggering such Event of
Default pursuant to clause (5) shall be remedied or cured by the Company or a
Restricted Subsidiary of the Company or waived by the holders of the relevant
indebtedness and no other Event of Default shall have occurred and be
continuing.

     The Holders of a majority in aggregate principal amount of the then
Outstanding Notes by written notice to the Trustee may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

     In the case of any Event of Default occurring 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 had then elected to redeem the notes pursuant to Section 3.07
hereof, an equivalent premium will also become and be immediately due and
payable to the extent permitted by law upon acceleration of the Notes.

Section 6.03  Other Remedies.

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

                                       54

<PAGE>

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

Section 6.04  Waiver of Past Defaults.

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

Section 6.05  Control by Majority.

     Holders of a majority in principal amount of the then Outstanding Notes may
direct the time, method and place of conducting any proceeding for exercising
any remedy available to the Trustee or exercising any trust or power conferred
on it. Subject to Sections 7.01 and 7.03, however, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture or that may
involve the Trustee in personal liability; provided, however, that subject to
the provisions of Section 315 of the TIA, the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction.

Section 6.06  Limitation on Suits.

     A Holder of a Note may pursue a remedy with respect to this Indenture or
the Notes only if:

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

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

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

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

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

     A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07  Rights of Holders of Notes to Receive Payment.

     Notwithstanding any other provision in this Indenture, the 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 interest on such Note on
the respective dates expressed in such Note for the payment thereof (or, in the
case of redemption, on the redemption 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 6.08  Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(a)(1) or (2) hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company, upon demand of the
Trustee, for the whole amount of principal of, and any premium and interest
remaining unpaid on, the Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09  Trustee May File Proofs of Claim.

     The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable and to take any and all actions
authorized under the TIA in order to have the claims of the Holders of the Notes
and the Trustee allowed in any judicial proceedings relative to the Company (or
any other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims, and any custodian in any
such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

Section 6.10  Priorities.

     If the Trustee collects any money pursuant to this Article 6, it shall pay
out the money in the following order:

          First:  to the Trustee for amounts due under Section 7.07 hereof;

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

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

     The Trustee, upon prior written notice to the Company, may fix a record
date and payment date for any payment to Holders of Notes pursuant to this
Section 6.10.

                                       56

Section 6.11  Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then Outstanding Notes.

Section 7.01  Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the
TIA. Notwithstanding the foregoing, no provision of this Indenture shall require
the Trustee to expend or risk its 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 7.01.

Section 7.02  Notice of Defaults.

specifically prescribed) may, in the absence of bad faith on its part, rely upon
an Officers' Certificate;

                                       57

liabilities which might be incurred by it in compliance with such request or
direction;

     (f) the Trustee shall not be bound to make any investigation into the facts

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

Section 7.09 Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $50,000,000. If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section 7.09,
the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.09, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article 7.

Section 7.10 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 7 shall become effective until the
acceptance of appointment by the successor Trustee under Section 7.11 hereof.

     (b) The Trustee may resign at any time by giving written notice thereof to
the Company no later than 20 business days prior to the proposed date of
resignation. If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

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

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 7.08 hereof 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 7.09 hereof
     and shall fail to resign after written request therefor by the Company or
     by any such Holder, or

                                       59

<PAGE>

          (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 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 6.11 hereof, 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 12.02 hereof. Each notice shall include the name of
the successor Trustee and the address of its Corporate Trust Office.

Section 7.11 Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder. Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts.

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

Section 7.12 Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such

                                       60

<PAGE>

authenticating Trustee may adopt such authentication and deliver the Notes so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Notes.

Section 7.13 Preferential Collection of Claims against Company.

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

Section 7.14 Reports by Trustee.

     (a) The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
TIA at the times and in the manner provided pursuant thereto.

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which the Notes
are listed, with the SEC and with the Company. The Company will notify the
Trustee when the Notes are listed on any stock exchange.

Section 7.15 Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents which shall be
authorized to act on behalf of the Trustee to authenticate Notes issued upon
original issue and upon exchange, registration of transfer or partial redemption
or repurchase or pursuant to Section 2.06 hereof, and Notes so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery
of Notes by the Trustee or the Trustee's certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section 7.15,
the combined capital and surplus of such Authenticating Agent 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 an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 7.15, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section 7.15.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 7.15, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a

                                       61

<PAGE>

notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 7.15, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders as their names and addresses appear in the Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section 7.15.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section 7.15, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 7.07 hereof.

     If an appointment is made pursuant to this Section 7.15, the Notes may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

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

                                                _______________________________,
                                                           As Trustee

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at the option of its Board of Directors evidenced by a
Board Resolution, at any time, elect to have either Section 8.02 or 8.03 hereof
be applied to all Outstanding Notes and the Subsidiary Guarantees, if any, upon
compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company and the Subsidiary Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all
Outstanding Notes (including the Subsidiary Guarantees) on the date the
conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For
this purpose, Legal Defeasance means that the Company and the Subsidiary
Guarantors will be deemed to have paid and discharged the entire Indebtedness
represented by the Outstanding Notes (including the Subsidiary Guarantees),
which will thereafter be deemed to be "Outstanding" only for the purposes of
Section 8.05 hereof and the other Sections of this Indenture referred to in
clauses (1) and (2) below, and to have satisfied all their other obligations
under such Notes, the Subsidiary Guarantees, if any, and this Indenture (and the
Trustee, on

                                       62

<PAGE>

demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which will survive
until otherwise terminated or discharged hereunder:

          (1) the rights of Holders of Outstanding Notes to receive payments in
     respect of the principal of, or interest or any premium on, such Notes when
     such payments are due from the trust referred to in Section 8.04 hereof;

          (2) the Company's obligations with respect to the Notes concerning
     issuing temporary Notes, registration of Notes, mutilated, destroyed, lost
     or stolen Notes and the maintenance of an office or agency for payment and
     money for security payments held in trust;

          (3) the rights, powers, trusts, duties and immunities of the Trustee
     hereunder and the Company's and the Subsidiary Guarantors' obligations in
     connection therewith; and

          (4) this Section 8.02.

     Subject to compliance with this Article 8, the Company may exercise its
option under this Section 8.02 notwithstanding the prior exercise of its option
under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and the Subsidiary Guarantors, if
any, will, subject to the satisfaction of the conditions set forth in Section
8.04 hereof, be released from each of their obligations under the covenants
contained in Sections 3.08, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14 and 4.15
hereof and clause (4) of Section 5.01(a) hereof with respect to the Outstanding
Notes on and after the date the conditions set forth in Section 8.04 hereof are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes will thereafter be
deemed not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but will continue to be deemed "Outstanding" for
all other purposes hereunder (it being understood that such Notes will not be
deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the Outstanding Notes and Subsidiary
Guarantees, if any, the Company and the Subsidiary Guarantors, if any, may omit
to comply with and will have no liability in respect of any term, condition or
limitation set forth in any such Section, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document, and such omission to comply will not constitute a Default or an Event
of Default under Section 6.01 hereof, but, except as specified above, the
remainder of this Indenture and such Notes and Subsidiary Guarantees, if any,
will be unaffected thereby. In addition, upon the Company's exercise under
Section 8.01 hereof of the option applicable to this Section 8.03, subject to
the satisfaction of the conditions set forth in Section 8.04 hereof, Section
6.01(a)(3) (with respect to a failure to comply with the provisions of Section
4.14 hereof or clause (4) of Section 5.01(a) hereof) and Sections 6.01(a)(4)
through 6.01(a)(6) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.02 or 8.03 hereof:

          (1) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders, cash in United States dollars, non-callable
     Government Securities, or a

                                       63

<PAGE>

     combination thereof, in such amounts as will be sufficient, in the opinion
     of a nationally recognized firm of independent public accountants, to pay
     the principal of, and any interest on, the Outstanding Notes on the stated
     date for payment thereof;

          (2) in the case of an election under Section 8.02 hereof, the Company
     has 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 (a copy of which shall
          accompany the Opinion of Counsel); or

              (B) since the date of this Indenture, there has been a change in
          the applicable federal income tax law,

     in either case to the effect that, and based thereon such Opinion of
     Counsel shall confirm that, the Holders of the Outstanding Notes will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such Legal Defeasance and will be subject to federal income tax on the
     same amounts, in the same manner and at the same times as would have been
     the case if such Legal Defeasance had not occurred;

          (3) in the case of an election under Section 8.03 hereof, the Company
     must deliver to the Trustee an Opinion of Counsel in the United States
     reasonably acceptable to the Trustee confirming that the Holders of the
     Outstanding Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Covenant Defeasance
     had not occurred;

          (4) no Default or Event of Default shall have occurred and be
     continuing on the date of 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 Restricted Subsidiaries is a party or by which the Company or
     any of its Restricted Subsidiaries is bound;

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

          (7) such Legal Defeasance or Covenant Defeasance shall not cause the
     Trustee to have a conflicting interest within the meaning of the TIA
     (assuming all Notes are in default within the meaning of such Act);

          (8) such Legal Defeasance or Covenant Defeasance shall not result in
     the trust arising from such deposit constituting an investment company
     within the meaning of the Investment Company Act of 1940, as amended,
     unless such trust shall be registered under such Act or exempt from
     registration thereunder; and

                                       64

<PAGE>

          (9) the Company must deliver to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     provided for or relating to the Legal Defeasance or the Covenant Defeasance
     have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust;
             Other Miscellaneous Provisions.

     Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the Outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent), as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, any premium and interest, but such
money need not be segregated from other funds except to the extent required by
law.

     The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

     Notwithstanding anything in this Article 8 to the contrary, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

Section 8.06 Repayment to Company.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, or any premium or
interest on, any Note and remaining unclaimed for two years after such principal
or any premium or interest has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged from
such trust; and the Holder of such Note will thereafter be permitted to 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, will thereupon cease.

Section 8.07 Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Subsidiary Guarantors', if any,
obligations under this Indenture and the Notes and the Subsidiary Guarantees, if
any, will be revived and reinstated as though no deposit had occurred pursuant
to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided that, if the Company makes any payment of
principal of, or any premium or interest on, any Note following the
reinstatement of its obligations, the Company will be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

          (5) to add to the covenants of the Company or any Subsidiary Guarantor
     or to the covenants applicable to any Restricted Subsidiary, in each case,

     legal rights under this Indenture of any such Holder;

     benefits to the Holders of the Notes or that does not adversely affect the

the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee will not be

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

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

          (6) make any change in the provisions of this Indenture relating to
     waivers of past Defaults or the rights of Holders of Notes to receive
     payments of principal of, or interest or any premium on, the Notes or
     impair the right to institute suit for the enforcement of any such payment
     on or after the date it is due;

          (7) waive a redemption payment with respect to any Note (other than a
     payment required under Section 3.08, 4.10 or 4.14 hereof);

          (8) release any Subsidiary Guarantor from any of its obligations under
     its Subsidiary Guarantee or this Indenture, except in accordance with the

          (9) make any change in Sections 6.04 or 6.07 hereof or in the
     foregoing amendment and waiver provisions in this Section 9.02.

     Upon the request of the Company accompanied by a Board Resolution
authorizing the execution of any such amended or supplemental Indenture, and
upon the filing with the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders of Notes as aforesaid, the Trustee will join with the
Company in the execution of such amended or supplemental Indenture unless such
amended or supplemental Indenture directly affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but will not be obligated to, enter into such
amended or supplemental Indenture.

<PAGE>

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

     After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company will mail to the Holders of Notes a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to
mail such notice, or any defect therein, will not, however, in any way impair or
affect the validity of any such amended or supplemental Indenture or waiver.
Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate
principal amount of the Notes then Outstanding may waive compliance in a
particular instance by the Company with any provision of this Indenture or the
Notes.

Section 9.03 Compliance with Trust Indenture Act.

     Every amendment or supplement to this Indenture or the Notes will be set
forth in a amended or supplemental Indenture that complies with the TIA as then
in effect.

Section 9.04 Effect of Consents.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Note is a continuing consent by the Holder of a Note and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. An amendment, supplement or waiver becomes effective in accordance with
its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

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

Section 9.06 Trustee to Sign Amendments, etc.

     The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental Indenture until its Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be provided with and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section
12.04 hereof, an Officers' Certificate and an Opinion of Counsel stating that
the execution of such amended or supplemental Indenture is authorized or
permitted by this Indenture.

Section 9.07 Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article 9, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Notes theretofore or thereafter authenticated and delivered hereunder shall
be bound thereby.

                              SUBSIDIARY GUARANTEES

Section 10.01  Subsidiary Guarantees.

     (a) Subject to this Article 10, each Restricted Subsidiary of the Company
designated by the Company from time to time as a Subsidiary Guarantor, upon
execution and delivery of a supplemental indenture substantially in the form of
Exhibit C hereto, shall jointly and severally unconditionally guarantee to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, irrespective of the validity and enforceability
of this Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that:

          (1) the principal of, and any premium and interest on, the Notes will
     be promptly paid in full when due, whether at maturity, by acceleration,
     redemption or otherwise, and interest on the overdue principal of and
     interest on the Notes, if any, if lawful, and all other obligations of the
     Company to the Holders or the Trustee hereunder or thereunder will be
     promptly paid in full or performed, all in accordance with the terms hereof
     and thereof; and

          (2) in case of any extension of time of payment or renewal of any
     Notes or any of such other obligations, that same will be promptly paid in
     full when due or performed in accordance with the terms of the extension or
     renewal, whether at the date scheduled to be paid, by acceleration or
     otherwise.

     In addition to the foregoing, by executing and delivering such supplemental
indenture, each Subsidiary Guarantor shall also agree, unconditionally and
jointly and severally with each other Subsidiary Guarantor, to pay any and all
expenses (including, without limitation, counsel fees and expenses) incurred by
the Trustee under this Indenture in enforcing any rights under a Subsidiary
Guarantee with respect to a Subsidiary Guarantor. Failing payment when due of
any amount so guaranteed or any performance so guaranteed for whatever reason,
the Subsidiary Guarantors shall be jointly and severally obligated to pay the
same immediately. Each Subsidiary Guarantor, by executing and delivering such
supplemental indenture, shall agree that this is a guarantee of payment and not
a guarantee of collection.

     (b) Each Subsidiary Guarantor, by executing and delivering such
supplemental indenture, shall agree 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 of the Notes with respect to any provisions
hereof or thereof, the recovery 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 Subsidiary
Guarantor, by executing and delivering such supplemental indenture, shall waive
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that its Subsidiary Guarantee will not be discharged except by
complete performance of the obligations contained in the Notes and this
Indenture or release in accordance with Section 10.05 hereof.

     (c) If any Holder or the Trustee is required by any court or otherwise to
return to the Company, a Subsidiary Guarantor or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or
the Subsidiary Guarantors, any amount paid by either to the Trustee or such
Holder, each Subsidiary Guarantee, to the extent theretofore discharged, will be
reinstated and be in full force and effect.

                                       69

<PAGE>

     (d) Each Subsidiary Guarantor, by executing and delivering such
supplemental indenture, shall agree that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
thereby until payment in full of all obligations guaranteed thereby. Each
Subsidiary Guarantor, by executing and delivering such supplemental indenture,
shall further agree that, as between the Subsidiary Guarantors, on the one hand,
and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed by the Subsidiary Guarantees may be accelerated as
provided in Article 6 hereof for the purposes of any Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed thereby, and (2) in the
event of any declaration of acceleration of such obligations as provided in
Article 6 hereof, such obligations (whether or not due and payable) will
forthwith become due and payable by the Subsidiary Guarantors for the purpose of
the Subsidiary Guarantees.

     (e) Except as provided herein, the provisions of this Article 10 cover all
agreements between the parties hereto relative to each Subsidiary Guarantee and
none of the parties shall be bound by any representation, warranty or promise
made by any Person relative thereto which is not embodied herein.

Section 10.02  Limitation on Subsidiary Guarantor Liability.

     Each Subsidiary Guarantor, by executing and delivering such supplemental
indenture, shall confirm, and by its acceptance of Notes, each Holder hereby
confirms, that it is the intention of all such parties that the Subsidiary
Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or
conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to
the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee and the Holders hereby irrevocably agree and each
Subsidiary Guarantor, by executing and delivering such supplemental indenture,
shall irrevocably agree that the obligations of such Subsidiary Guarantor will
be limited to the maximum amount that will, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Subsidiary
Guarantor that are relevant under such laws, result in the obligations of such
Subsidiary Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

Section 10.03  Execution and Delivery of Subsidiary Guarantee.

     To evidence each Subsidiary Guarantee, the Company shall cause a Subsidiary
Guarantee substantially in the form attached as Exhibit B hereto to be endorsed
by an Officer of each Subsidiary Guarantor and shall cause an indenture
supplemental to this Indenture substantially in the form of Exhibit C hereto to
be executed on behalf of such Guarantor by one of its Officers. The signature of
any such Officers on the Subsidiary Guarantee may be manual or facsimile.

     Each Subsidiary Guarantor, by executing and delivering such supplemental
indenture, shall agree that its Subsidiary Guarantee will remain in full force
and effect notwithstanding any failure to endorse such Subsidiary Guarantee.

     If an Officer whose signature is on this Indenture or on a Subsidiary
Guarantee no longer holds that office at the time a Subsidiary Guarantee is
endorsed, such Subsidiary Guarantee will be valid nevertheless.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in
any indenture supplemental to this Indenture on behalf of the Subsidiary
Guarantors and each of them.

Section 10.04  Subsidiary Guarantors May Consolidate, etc., on Certain Terms.

     (a) Except as otherwise provided in Section 10.05 hereof, no Subsidiary
Guarantor may sell or otherwise dispose of all or substantially all of its
assets to, or consolidate with or merge with or into, any Person that is (either
before or after giving effect to such transaction) an Affiliate of the Company,
unless that Affiliate unconditionally assumes all of the obligations of such
Subsidiary Guarantor, pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee, under the Notes, this Indenture and the
Subsidiary Guarantee, on the terms set forth herein or therein.

     (b) Except as otherwise provided in Section 10.05 hereof, no Subsidiary
Guarantor may sell or otherwise dispose of all or substantially all of its
assets to, or consolidate with or merge with or into, any Person that is not an
Affiliate of the Company (whether or not such Subsidiary Guarantor is the
surviving Person) unless:

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

          (2) the Net Proceeds of such sale or other disposition are applied in
     accordance with the applicable provisions of this Indenture, including
     without limitation, Section 4.10 hereof.

     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the
Subsidiary Guarantee endorsed upon the Notes and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Guarantor, such successor Person shall succeed to and be
substituted for the Subsidiary Guarantor with the same effect as if it had been
named herein as a Subsidiary Guarantor. Such successor Person 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 not 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.

     Except as set forth in Articles 4 and 5 hereof, and notwithstanding Section
10.04(b)(2), nothing contained in this Indenture or in any of the Notes will
prevent any consolidation or merger of a Subsidiary Guarantor with or into the
Company, or will prevent any sale or conveyance of the property of the Guarantor
as an entirety or substantially as an entirety to the Company.

     (c) For purposes of this Section 10.04, beneficial ownership of 35% or more
of the Voting Stock of a Person will be deemed to be control.

Section 10.05 Releases.

     (a) Notwithstanding the provisions of Section 10.04 hereof, a Subsidiary
Guarantor will be released automatically and relieved of any obligations under
its Subsidiary Guarantee:

          (1) upon the sale or other disposition of all or substantially all of
     the assets of such Subsidiary Guarantor (including by way of merger or
     consolidation) to a Person that is not (either before or after giving
     effect to such transaction) the Company or an Affiliate of the Company, if
     the sale or other disposition complies with Sections 3.08 and 4.10 hereof
     and the Subsidiary Guarantor either no longer has any Indebtedness (other
     than its Subsidiary Guarantee) after

                                       71

<PAGE>

     compliance with such Sections or it would be permitted at the time of such
     release to incur all of its then outstanding Indebtedness in compliance
     with Section 4.09 hereof;

          (2) upon the sale of all of the Capital Stock of such Subsidiary
     Guarantor to a Person that is not (either before or after giving effect to
     such transaction) an Affiliate of the Company, if the sale complies with
     Sections 3.08 and 4.10 hereof;

          (3) upon the legal defeasance of the Notes as described in Article 8
     hereof; or

          (4) upon (i) the merger of such Subsidiary Guarantor into the Company
     or another Subsidiary Guarantor; (ii) the dissolution of the Subsidiary
     Guarantor into the Company or another Subsidiary Guarantor; or (iii) the
     transfer of all or substantially all of the assets of such Subsidiary
     Guarantor to the Company or another Subsidiary Guarantor; or

          (5) at the option of the Company, if at any time the Subsidiary
     Guarantor has no Indebtedness outstanding other than its Subsidiary
     Guarantee or, assuming it ceased to be a Subsidiary Guarantor but continued
     to be a Restricted Subsidiary of the Company following such release, it
     would be permitted at the time of such release to incur all of its then
     outstanding Indebtedness in compliance with Section 4.09 hereof.

     (b) Upon delivery by the Company to the Trustee of an Officers' Certificate
and, if requested by the Trustee, an Opinion of Counsel to the effect that one
of the events described in Section 10.05(a) hereof has occurred in accordance
with the provisions of this Indenture with respect to any Subsidiary Guarantor,
the Trustee will execute any documents reasonably required in order to evidence
the release of such Subsidiary Guarantor from its obligations under its
Subsidiary Guarantee.

                                  ARTICLE 11.
                           SATISFACTION AND DISCHARGE

Section 11.01  Satisfaction and Discharge.

     This Indenture will be discharged and will cease to be of further effect as
to all Notes issued hereunder, when:

          (1) either:

              (a) all Notes that have been authenticated (except lost, stolen
          or destroyed Notes that have been replaced or paid and Notes for whose
          payment money has theretofore been deposited in trust and thereafter
          repaid to the Company) have been delivered to the Trustee for
          cancellation; or

              (b) all Notes that have not been delivered to the Trustee for
          cancellation have become due and payable by reason of the giving of a
          notice of redemption or otherwise or will become due and payable
          within one year and the Company or any Subsidiary Guarantor has
          irrevocably deposited or caused to be deposited with the Trustee as
          trust funds in trust solely for the benefit of the Holders, cash in
          U.S. dollars, non-callable Government Securities, or a combination
          thereof, in such amounts as will be sufficient without consideration
          of any reinvestment of interest, to pay and discharge the

                                       72

<PAGE>

          entire indebtedness on the Notes not delivered to the Trustee for
          cancellation for principal, any premium and accrued interest to the
          date of maturity or redemption;

          (2) no Default or Event of Default has occurred and is continuing on
     the date of such deposit or will occur as a result of such deposit and such
     deposit will not result in a breach or violation of, or constitute a
     default under, any other instrument to which the Company or any Subsidiary
     Guarantor is a party or by which the Company or any Subsidiary Guarantor is
     bound;

          (3) the Company or any Subsidiary Guarantor has paid or caused to be
     paid all sums payable by it under this Indenture; and

          (4) the Company has delivered irrevocable instructions to the Trustee
     under this Indenture to apply the deposited money toward the payment of the
     Notes at maturity or the redemption date, as the case may be.

     In addition, the Company must deliver an Officers' Certificate and an
Opinion of Counsel to the Trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied.

     Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 11.01, the provisions of Section 11.02 and Section 8.06 hereof will
survive.

Section 11.02  Application of Trust Money.

     Subject to the provisions of Section 8.06 hereof, all money deposited with
the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied
by it, in accordance with the provisions of the 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 Persons
entitled thereto, of the principal (and any premium) and interest for whose
payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law.

     If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with Section 11.01 hereof by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's and any Subsidiary Guarantor's obligations under this Indenture and
the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 11.01 hereof; provided that (a) if the Company has made any
payment of principal of, or any premium or interest on, any Notes because of 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 or
Government Securities held by the Trustee or Paying Agent and (b) the Trustee or
Paying Agent shall return all such money and Government Securities to the
Company promptly after receiving a request therefor at any time, if such
reinstatement of the Company's obligations has occurred and continues to be in
effect.

[Insert the Global Note Legend, if applicable pursuant to the provisions of the
Indenture]

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

          (1) Interest. Medco Health Solutions, Inc., a Delaware corporation
     (the "Company"), promises to pay interest on the principal amount of this
     Note at     % per annum from July     , 2003 until maturity. The Company
     will pay interest, if any, semi-annually in arrears on       and      of
     each year, or if any such day is not a Business Day, on the next succeeding
     Business Day (each, an "Interest Payment Date"). Interest on the Notes will
     accrue from the most recent date to which interest has been paid or, if no
     interest has been paid, from the date of issuance; provided that if there
     is no existing Default in the payment of interest, and if this Note is
     authenticated between a Regular Record Date referred to on the face hereof
     and the next succeeding Interest Payment Date, interest shall accrue from
     such next succeeding Interest Payment Date; provided, further, that the
     first Interest Payment Date shall be       , 2004. Interest will be
     computed on the basis of a 360-day year of twelve 30-day months. The rate
     of interest payable on overdue principal and interest, including
     post-petition interest, shall be increased, to the extent lawful, by 1% per
     annum unless a Fall Away Event shall have occurred. The Company may, to the
     extent required to do so by law, deduct or withhold income or other similar
     taxes imposed by the United States of America from principal or interest
     payments on the Notes.

          (2) Method of Payment. The Company will pay interest on the Notes
     (except Defaulted Interest) to the Persons who are registered Holders of
     Notes at the close of business on the      or      next preceding the
     Interest Payment Date (each, a "Regular Record Date"), even if such Notes
     are canceled after such Regular Record date and on or before such Interest
     Payment Date, except as provided in Section 2.07 of the Indenture with
     respect to Defaulted Interest. If this Note is a Global Note, the Company
     will pay all principal of, and interest and any premium on, this Note to
     the Depositary or its nominee as the registered holder of this Note in
     immediately available funds. All other payments on the Notes will be made
     at the office or agency of the Company maintained for such purpose within
     the City and State of New York, or, at the option of the Company, payment
     of interest may be made by check mailed to the Holders at their addresses
     set forth in the Register. All payments on the Notes will be in such coin
     or currency of the United States of America as at the time of payment is
     legal tender for payment of public and private debts.

          (3) Paying Agent and Registrar. Initially, U.S. Bank Trust National
     Association, the Trustee under the Indenture, will act as Paying Agent and
     Registrar. The Company or any of its Subsidiaries may act in any such
     capacity. The Company shall notify each Holder on any change in any Paying
     Agent or Registrar.

          (4) Indenture. The Company issued the Notes under an Indenture dated
     as of July    , 2003 (the "Indenture") between the Company and the Trustee.
     The terms of the Notes include those stated in the Indenture and those made
     part of the Indenture by reference to the Trust Indenture Act of 1939, as
     amended (15 U.S. Code (SS) 77aaa-77bbbb). The Notes are subject to all such
     terms, and Holders are referred to the Indenture and such Act for a
     statement of such terms. To the extent any provision of this Note conflicts
     with the express provisions of

                                       A-2

<PAGE>

     the Indenture, the provisions of the Indenture shall govern and be
     controlling. The Notes are unsecured obligations of the Company.

          (5) Optional Redemption. The Company may at any time at its option
     redeem all or part of the Notes upon not less than 30 days' nor more than
     60 days' prior notice at a redemption price equal to the greater of (1)
     100% of the principal amount of the Notes being redeemed and (2) as
     determined by the Quotation Agent, the sum of the present values of 100% of
     the principal amount of the Notes being redeemed, plus all scheduled
     payments of interest on such Notes to and including July    , 2013 (but not
     including accrued and unpaid interest to the redemption date), in each case
     discounted to the redemption date on a semi-annual basis (assuming a
     360-day year consisting of twelve 30-day months) at the Adjusted Treasury
     Rate plus 50 basis points, together in each case (unless the Notes are
     redeemed or purchased on or after a Regular Record Date but on or prior to
     the related Interest Payment Date) with any accrued and unpaid interest to
     the applicable redemption date.

          (6) Repurchase at option of holder.

              (a) Upon the occurrence of a Change of Control Event, unless the
     Company has exercised its right to redeem the Notes as provided in Section
     3.07 of the Indenture, the Company will be required to make an offer to
     repurchase all or any part (equal to $1,000 or an integral multiple
     thereof) of each Holder's Notes at a repurchase price in cash equal to 101%
     of the aggregate principal amount thereof plus accrued and unpaid interest
     thereon, if any, to the date of purchase in accordance with the procedures
     set forth in the Indenture.

              (b) If the Company or any Restricted Subsidiary consummates any
     Asset Sales, within 30 days of each date on which the aggregate amount of
     Excess Proceeds exceeds $100 million, the Company will commence an offer to
     all Holders of Notes, and at the Company's option, to all holders of other
     Indebtedness that is pari passu with, or subordinate in right of payment
     to, the Notes pursuant to Section 3.08 of the Indenture to purchase the
     maximum principal amount of Notes and other Indebtedness that may be
     purchased out of the Excess Proceeds at an offer price in cash in an amount
     equal to 100% of the principal amount thereof (or 100% of the accreted
     value thereof, in the case of other Indebtedness that was initially offered
     and sold at a discount) plus accrued and unpaid interest, if any, to the
     date fixed for the closing of such offer in accordance with the procedures
     set forth in the Indenture.

          (7) Notice of Redemption. Notice of redemption will be mailed at least
     30 days but not more than 60 days before the redemption date to each Holder
     whose Notes are to be redeemed at its registered address. No Notes of
     $1,000 or less may be redeemed in part. On and after the redemption date,
     interest will cease to accrue on Notes or portions thereof called for
     redemption if the Company shall have complied with the applicable
     provisions of the Indenture.

          (8) Denominations, Transfer, Exchange. The Notes are in fully
     registered form without coupons in denominations of $1,000 and integral
     multiples thereof. The transfer of Notes may be registered and Notes may be
     exchanged as provided in the Indenture. The Company and the Registrar may
     require a Holder, among other things, to furnish appropriate endorsements
     and transfer documents and the Company may require payment of a sum
     sufficient to cover any tax or other governmental charge that may be
     imposed in connection with any registration of transfer or exchange of
     Notes. 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 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

                                      A-3

<PAGE>

     selected for redemption in whole or in part, except the unredeemed portion
     of any Note being redeemed in part.

          (9)  Persons Deemed Owners. Prior to due presentment of a Note for
     registration of transfer, the Company, the Trustee and any agent of the
     Company or the Trustee may treat the Person in whose name such Note is
     registered as the owner of such Note for the purpose of receiving payment
     of principal of (and premium, if any) and interest on such Note and for all
     other purposes whatsoever, whether or not such Note be overdue, and neither
     the Company, the Trustee nor any agent of the Company or the Trustee shall
     be affected by notice to the contrary.

          (10) Amendment, Supplement and Waiver. Subject to certain exceptions,
     the Indenture or the Notes may be amended or supplemented with the consent
     of the Holders of at least a majority in principal amount of the Notes
     (including without limitation any Additional Notes) then Outstanding, and
     any existing default or compliance with any provision of the Indenture or
     the Notes may be waived with the consent of the Holders of a majority in
     principal amount of the then Outstanding Notes, including Additional Notes,
     if any). Without the consent of any Holder of a Note, the Indenture, the
     Subsidiary Guarantees or the Notes may be amended or supplemented, among
     other things, to cure any ambiguity, defect, omission or inconsistency, to
     provide for uncertificated Notes in addition to or in place of certificated
     Notes, to provide for the assumption of the Company's obligations to
     Holders of the Notes in case of a merger or consolidation or sale of all or
     substantially all of the Company's assets, to add guarantees with respect
     to the Notes, to add covenants, to make any change that would provide any
     additional rights or benefits to the Holders of the Notes or that does not
     adversely affect the rights under the Indenture of any such Holder, to
     comply with the requirements of the SEC in order to effect or maintain the
     qualification of the Indenture under the Trust Indenture Act, to provide
     for the issuance of Additional Notes in accordance with the limitations set
     forth in the Indenture or to evidence and provide for the acceptance and
     appointment of a successor Trustee.

          (11) Defaults and Remedies. If any Event of Default occurs and is
     continuing, the Trustee or the Holders of at least 25% in principal amount
     of the then Outstanding Notes may declare all the Notes to be due and
     payable. Notwithstanding the foregoing, in the case of an Event of Default
     arising from certain events of bankruptcy or insolvency, all Outstanding
     Notes will become due and payable without further action or notice. Holders
     may not enforce the Indenture or the Notes except as provided in the
     Indenture. Subject to certain limitations, Holders of a majority in
     principal amount of the then Outstanding Notes may direct the Trustee in
     its exercise of any trust or power. The Holders of a majority in aggregate
     principal amount of the Notes then Outstanding by notice to the Trustee may
     on behalf of the Holders of all of the Notes waive any existing Default or
     Event of Default and its consequences under the Indenture except a
     continuing Default or Event of Default in the payment of interest or
     premium on, or the principal of, the Notes.

          (12) No Recourse Against Others. No director, officer, employee,
     incorporator or stockholder of the Company or any Subsidiary Guarantor, as
     such, will have any liability for any obligations of the Company or any
     Subsidiary Guarantor under the Notes, any Subsidiary Guarantee or the
     Indenture or for any claim based on, in respect of, or by reason of, such
     obligations or their creation. Each Holder by accepting a Note waives and
     releases all such liability. The waiver and release are part of the
     consideration for the issuance of the Notes.

          (13) Authentication. This Note will not be valid until authenticated
     by the manual signature of the Trustee or an Authenticating Agent.

subsidiary of Medco Health Solutions, Inc. (or its permitted successor), a
Delaware corporation (the "Company"), and U.S. Bank Trust National Association,
as trustee under the indenture referred to below (the "Trustee").

                               W I T N E S S E T H

     WHEREAS, the Company has heretofore executed and delivered to the Trustee
an indenture (the "Indenture"), dated as of July    , 2003 providing for the
issuance of an aggregate principal amount of up to $500 million of     % Senior

as permitted under the Indenture;

     WHEREAS, the Indenture provides that the Company may cause any of its
direct or indirect Restricted Subsidiaries to become a Subsidiary Guarantor by
executing and delivering to the Trustee a supplemental indenture pursuant to
which the Subsidiary Guarantor shall unconditionally guarantee all of the
Company's Obligations under the Notes and the Indenture on the terms and
conditions set forth herein (the "Subsidiary Guarantee"); and

     WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Subsidiary Guarantor and the Trustee mutually covenant and agree for the equal
and ratable benefit of the Holders of the Notes as follows:

     1.   Capitalized Terms. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

     2.   Agreement to Guarantee. The Subsidiary Guarantor hereby agrees as
follows:

               (a) To guarantee, jointly and severally with each other
          Subsidiary Guarantor heretofore or hereafter designated as such by the
          Company, to each Holder of a Note authenticated and delivered by the
          Trustee and to the Trustee and its successors and assigns,
          irrespective of the validity and enforceability of the Indenture, the
          Notes or the obligations of the Company hereunder or thereunder, that:

                   (i)  the principal of, and any premium and interest on, the
               Notes will be promptly paid in full when due, whether at
               maturity, by acceleration, redemption or otherwise, and interest
               on the overdue principal of and interest on the Notes, if any, if
               lawful, and all other obligations of the Company to the Holders
               or the Trustee hereunder or thereunder will be promptly paid in
               full or performed, all in accordance with the terms hereof and
               under the Indenture; and

                   (ii) in case of any extension of time of payment or renewal
               of any Notes or any of such other obligations, that same will be
               promptly paid in full

<PAGE>

               when due or performed in accordance with the terms of the
               extension or renewal, whether at the date scheduled to be paid,
               by acceleration or otherwise.

          Failing payment when due of any amount so guaranteed or any
          performance so guaranteed for whatever reason, the Subsidiary
          Guarantor shall be obligated to pay the same immediately. The
          Subsidiary Guarantor hereby agrees that this is a guarantee of payment
          and not a guarantee of collection.

               (b) The obligations hereunder shall be unconditional,
          irrespective of the validity, regularity or enforceability of the
          Notes or the Indenture, the absence of any action to enforce the same,
          any waiver or consent by any Holder of the Notes with respect to any
          provisions hereof or thereof, the recovery 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 the Subsidiary Guarantor.

               (c) The Subsidiary Guarantor hereby waives diligence,
          presentment, demand of payment, filing of claims with a court in the
          event of insolvency or bankruptcy of the Company, any right to require
          a proceeding first against the Company, protest, notice and all
          demands whatsoever.

               (d) This Subsidiary Guarantee shall not be discharged except by
          complete performance of the obligations contained in the Notes and the
          Indenture or release in accordance with the Indenture, and the
          Subsidiary Guarantor accepts all obligations of a Subsidiary Guarantor
          under the Indenture.

               (e) If any Holder or the Trustee is required by any court or
          otherwise to return to the Company, any Subsidiary Guarantor, or any
          custodian, trustee, liquidator or other similar official acting in
          relation to either the Company or the Subsidiary Guarantor, any amount
          paid by either to the Trustee or such Holder, this Subsidiary
          Guarantee, to the extent theretofore discharged, shall be reinstated
          in full force and effect.

               (f) The Subsidiary Guarantor 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.

               (g) As between the Subsidiary Guarantors, 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 6 of the Indenture for the purposes of this Subsidiary
          Guarantee, notwithstanding any stay, injunction or other prohibition
          preventing such acceleration in respect of the obligations guaranteed
          hereby, and (y) in the event of any declaration of acceleration of
          such obligations as provided in Article 6 of the Indenture, such
          obligations (whether or not due and payable) shall forthwith become
          due and payable by the Subsidiary Guarantors for the purpose of this
          Subsidiary Guarantee.

               (h) Pursuant to Section 10.02 of the Indenture, after giving
          effect to any maximum amount and all other contingent and fixed
          liabilities that are relevant under any applicable Bankruptcy or
          fraudulent conveyance laws, this Subsidiary Guarantee shall be limited
          to the maximum amount permissible such that the obligations of the
          Subsidiary

                                      C-2

<PAGE>

          Guarantor under this Subsidiary Guarantee will not constitute a
          fraudulent transfer or conveyance.

     3.   Execution and Delivery. The Subsidiary Guarantor agrees that the
Subsidiary Guarantee shall remain in full force and effect notwithstanding any
failure to endorse such Subsidiary Guarantee.

     4.   Subsidiary Guarantor May Consolidate, Etc. on Certain Terms.

               (a)  Except as otherwise provided in Section 5 hereof, the
          Subsidiary Guarantor shall not sell or otherwise dispose of all or
          substantially all of its assets to, or consolidate with or merge with
          or into, any Person that is (either before or after giving effect to
          such transaction) an Affiliate of the Company, unless that Affiliate
          unconditionally assumes all of the obligations of the Subsidiary
          Guarantor pursuant to a supplemental indenture in form and substance
          reasonably satisfactory to the Trustee, under the Notes, the Indenture
          and the Subsidiary Guarantee on the terms set forth therein.

               (b)  Except as otherwise provided in Section 5 hereof, the
          Subsidiary Guarantor shall not sell or otherwise dispose of all or
          substantially all of its assets to, or consolidate with or merge with
          or into, any Person that is not an Affiliate of the Company (whether
          or not the Subsidiary Guarantor is the surviving Person) other than
          the Company unless:

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

                    (ii) the Net Proceeds of such sale or other disposition are
               applied in accordance with the applicable provisions of the
               Indenture, including without limitation, Section 4.10 of the
               Indenture.

               In case of any such consolidation, merger, sale or conveyance and
          upon the assumption by the successor Affiliate, by supplemental
          indenture, executed and delivered to the Trustee and satisfactory in
          form to the Trustee, of the Subsidiary Guarantee and the due and
          punctual performance of all of the covenants and conditions of the
          Indenture to be performed by the Subsidiary Guarantor, such successor
          Affiliate will succeed to and be substituted for the Subsidiary
          Guarantor with the same effect as if it had been named therein as the
          Subsidiary Guarantor. Such successor Affiliate thereupon may cause to
          be signed the Subsidiary Guarantee of the Notes issuable hereunder
          which theretofore shall not have been signed by the Company and
          delivered to the Trustee. The Subsidiary Guarantee so issued will in
          all respects have the same legal rank and benefit under the Indenture
          as the Subsidiary Guarantees theretofore and thereafter issued in
          accordance with the terms of the Indenture as though the Subsidiary
          Guarantee had been issued at the date of the execution of the
          Indenture.

               Except as set forth in Articles 4 and 5 of the Indenture, and
          notwithstanding Section 4(b)(ii) hereof, nothing contained in the
          Indenture or in any of the Notes will prevent any consolidation or
          merger of the Subsidiary Guarantor with or into the Company, or will
          prevent any sale or conveyance of the property of the Subsidiary
          Guarantor as an entirety or substantially as an entirety to the
          Company.

                                       C-3

<PAGE>

               (c)  For purposes of this Section 4, beneficial ownership of 35%
          or more of the Voting Stock of a Person will be deemed to be control.

     5.   Releases.

               (a)  Notwithstanding the provisions of Section 4 hereof, the
          Subsidiary Guarantor will be released automatically and relieved of
          any obligations under its Subsidiary Guarantee:

                    (i)    upon the sale or other disposition of all or
               substantially all of the assets of such Subsidiary Guarantor
               (including by way of merger or consolidation) to a Person that is
               not (either before or after giving effect to such transaction)
               the Company or an Affiliate of the Company, if the sale or other
               disposition complies with Sections 3.08 and 4.10 of the Indenture
               and the Subsidiary Guarantor either no longer has an Indebtedness
               (other than the Subsidiary Guarantee) after compliance with such
               Sections or it would be permitted at the time of such release to
               incur all of its then outstanding Indebtedness in compliance with
               Section 4.09 of the Indenture,

                    (ii)   upon the sale of all of the Capital Stock of the
               Subsidiary Guarantor to a Person that is not (either before or
               after giving effect to such transaction) an Affiliate of the
               Company, if the sale complies with Sections 3.08 and 4.10 of the
               Indenture;

                    (iii)  upon the legal defeasance of the Notes as described
               in Article 8 of the Indenture;

                    (iv)   upon (a) the merger of the Subsidiary Guarantor into
               the Company or another Subsidiary Guarantor; (b) the dissolution
               of the Subsidiary Guarantor into the Company or another
               Subsidiary Guarantor; or (c) the transfer of all or substantially
               all of the assets of the Subsidiary Guarantor to the Company or
               another Subsidiary Guarantor; or

                    (v)    at the option of the Company, if at any time the
               Subsidiary Guarantor has no Indebtedness outstanding other than
               the Subsidiary Guarantee or, assuming it ceased to be a
               Subsidiary Guarantor but continued to be a Restricted Subsidiary
               of the Company following such release, it would be permitted at
               the time of such release to incur all of its then outstanding
               Indebtedness in compliance with Section 4.09 of the Indenture.

               Upon delivery by the Company to the Trustee of an Officers'
          Certificate and an Opinion of Counsel to the effect that one of the
          events described in this Section 5 has occurred in accordance with the
          provisions of the Indenture, the Trustee will execute any documents
          reasonably required in order to evidence the release of the Subsidiary
          Guarantor from its obligations under its Subsidiary Guarantee.

     6.   No Recourse Against Others. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Subsidiary
Guarantor, as such, shall have any liability for any obligations of the Company
or the Guarantor under the Notes, the Subsidiary Guarantee, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or

                                       C-4

their creation. Each Holder of the Notes by accepting a Note waives and releases
all such liability. The waiver and release are part of the consideration for
issuance of the Notes.

     7.   Successors and Assigns. All covenants agreements of any Subsidiary
Guarantor in this Indenture supplemental will bind its successors and assigned,
whether so expressed or not, except as otherwise provided in Section 5 hereof.

     8.   Separability. In case any provision in this Supplemental Indenture or
in the Subsidiary Guarantee is invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions will not in any way be
affected or impaired thereby.

     8.   Governing Law. This Supplemental Indenture and the Subsidiary
Guarantee shall be governed by and construed in accordance with the laws of the
State of New York.

     9.   Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

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

          (1) Interest. Medco Health Solutions, Inc., a Delaware corporation
     (the "Company"), promises to pay interest on the principal amount of this
     Note at    % per annum from July     , 2003 until maturity. The Company
     will pay interest, if any, semi-annually in arrears on     and     of each
     year, or if any such day is not a Business Day, on the next succeeding
     Business Day (each, an "Interest Payment Date"). Interest on the Notes will
     accrue from the most recent date to which interest has been paid or, if no
     interest has been paid, from the date of issuance; provided that if there
     is no existing Default in the payment of interest, and if this Note is
     authenticated between a Regular Record Date referred to on the face hereof
     and the next succeeding Interest Payment Date, interest shall accrue from
     such next succeeding Interest Payment Date; provided, further, that the
     first Interest Payment Date shall be    , 2004. Interest will be computed
     on the basis of a 360-day year of twelve 30-day months. The rate of
     interest payable on overdue principal and interest, including post-petition
     interest, shall be increased, to the extent lawful, by 1% per annum unless
     a Fall Away Event shall have occurred. The Company may, to the extent
     required to do so by law, deduct or withhold income or other similar taxes
     imposed by the United States of America from principal or interest payments
     on the Notes.

          (2) Method of Payment. The Company will pay interest on the Notes
     (except Defaulted Interest) to the Persons who are registered Holders of
     Notes at the close of business on the     or    next preceding the Interest
     Payment Date (each, a "Regular Record Date"), even if such Notes are
     canceled after such Regular Record date and on or before such Interest
     Payment Date, except as provided in Section 2.07 of the Indenture with
     respect to Defaulted Interest. If this Note is a Global Note, the Company
     will pay all principal of, and interest and any premium on, this Note to
     the Depositary or its nominee as the registered holder of this Note in
     immediately available funds. All other payments on the Notes will be made
     at the office or agency of the Company maintained for such purpose within
     the City and State of New York, or, at the option of the Company, payment
     of interest may be made by check mailed to the Holders at their addresses
     set forth in the Register. All payments on the Notes will be in such coin
     or currency of the United States of America as at the time of payment is
     legal tender for payment of public and private debts.

          (3) Paying Agent and Registrar. Initially, U.S. Bank Trust National
     Association, the Trustee under the Indenture, will act as Paying Agent and
     Registrar. The Company or any of its Subsidiaries may act in any such
     capacity. The Company shall notify each Holder on any change in any Paying
     Agent or Registrar.

          (4) Indenture. The Company issued the Notes under an Indenture dated
     as of July    , 2003 (the "Indenture") between the Company and the Trustee.

     redeem all or part of the Notes upon not less than 30 days' nor more than

     100% of the principal amount of the Notes being redeemed and (2) as

     the principal amount of the Notes being redeemed, plus all scheduled
     payments of interest on such Notes to and including July   , 2013 (but not
     including accrued and unpaid interest to the redemption date), in each case
     discounted to the redemption date on a semi-annual basis (assuming a
     360-day year consisting of twelve 30-day months) at the Adjusted Treasury
     Rate plus 50 basis points, together in each case (unless the Notes are
     redeemed or purchased on or after a Regular Record Date but on or prior to
     the related Interest Payment Date) with any accrued and unpaid interest to
     the applicable redemption date.

          (6) Repurchase at Option of Holder.

              (a) Upon the occurrence of a Change of Control Event, unless the
     Company has exercised its right to redeem the Notes as provided in Section
     3.07 of the Indenture, the Company will be required to make an offer to
     repurchase all or any part (equal to $1,000 or an integral multiple
     thereof) of each Holder's Notes at a repurchase price in cash equal to 101%
     of the aggregate principal amount thereof plus accrued and unpaid interest
     thereon, if any, to the date of purchase in accordance with the procedures
     set forth in the Indenture.

              (b) If the Company or any Restricted Subsidiary consummates any
     Asset Sales, within 30 days of each date on which the aggregate amount of
     Excess Proceeds exceeds $100 million, the Company will commence an offer to
     all Holders of Notes, and at the Company's option, to all holders of other
     Indebtedness that is pari passu with, or subordinate in right of payment
     to, the Notes pursuant to Section 3.08 of the Indenture to purchase the
     maximum principal amount of Notes and other Indebtedness that may be
     purchased out of the Excess Proceeds at an offer price in cash in an amount
     equal to 100% of the principal amount thereof (or 100% of the accreted
     value thereof, in the case of other Indebtedness that was initially offered
     and sold at a discount) plus accrued and unpaid interest, if any, to the
     date fixed for the closing of such offer in accordance with the procedures
     set forth in the Indenture.

          (7) Notice of Redemption. Notice of redemption will be mailed at least
     30 days but not more than 60 days before the redemption date to each Holder
     whose Notes are to be redeemed at its registered address. No Notes of
     $1,000 or less may be redeemed in part. On and after the redemption date,

     provisions of the Indenture.

     registered form without coupons in denominations of $1,000 and integral
     multiples thereof. The transfer of Notes may be registered and Notes may be

     require a Holder, among other things, to furnish appropriate endorsements
     and transfer documents and the Company may require payment of a sum
     sufficient to cover any tax or other governmental charge that may be
     imposed in connection with any registration of transfer or exchange of
     Notes. 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 and ending at the close of business on the

     selected for redemption in whole or in part, except the unredeemed portion
     of any Note being redeemed in part.

          (9)  Persons Deemed Owners. Prior to due presentment of a Note for
     registration of transfer, the Company, the Trustee and any agent of the
     Company or the Trustee may treat the Person in whose name such Note is

     of principal of (and premium, if any) and interest on such Note and for all
     other purposes whatsoever, whether or not such Note be overdue, and neither
     the Company, the Trustee nor any agent of the Company or the Trustee shall
     be affected by notice to the contrary.

          (10) Amendment, Supplement and Waiver. Subject to certain exceptions,
     the Indenture or the Notes may be amended or supplemented with the consent
     of the Holders of at least a majority in principal amount of the Notes
     (including without limitation any Additional Notes) then Outstanding, and
     any existing default or compliance with any provision of the Indenture or
     the Notes may be waived with the consent of the Holders of a majority in
     principal amount of the then Outstanding Notes, including Additional Notes,
     if any). Without the consent of any Holder of a Note, the Indenture, the
     Subsidiary Guarantees or the Notes may be amended or supplemented, among
     other things, to cure any ambiguity, defect, omission or inconsistency, to
     provide for uncertificated Notes in addition to or in place of certificated
     Notes, to provide for the assumption of the Company's obligations to
     Holders of the Notes in case of a merger or consolidation or sale of all or
     substantially all of the Company's assets, to add guarantees with respect
     to the Notes, to add covenants, to make any change that would provide any
     additional rights or benefits to the Holders of the Notes or that does not
     adversely affect the rights under the Indenture of any such Holder, to
     comply with the requirements of the SEC in order to effect or maintain the
     qualification of the Indenture under the Trust Indenture Act, to provide
     for the issuance of Additional Notes in accordance with the limitations set
     forth in the Indenture or to evidence and provide for the acceptance and
     appointment of a successor Trustee.

          (11) Defaults and Remedies. If any Event of Default occurs and is
     continuing, the Trustee or the Holders of at least 25% in principal amount
     of the then Outstanding Notes may declare all the Notes to be due and
     payable. Notwithstanding the foregoing, in the case of an Event of Default
     arising from certain events of bankruptcy or insolvency, all Outstanding
     Notes will become due and payable without further action or notice. Holders
     may not enforce the Indenture or the Notes except as provided in the
     Indenture. Subject to certain limitations, Holders of a majority in
     principal amount of the then Outstanding Notes may direct the Trustee in
     its exercise of any trust or power. The Holders of a majority in aggregate
     principal amount of the Notes then Outstanding by notice to the Trustee may
     on behalf of the Holders of all of the Notes waive any existing Default or
     Event of Default and its consequences under the Indenture except a
     continuing Default or Event of Default in the payment of interest or
     premium on, or the principal of, the Notes.

          (12) No Recourse Against Others. No director, officer, employee,
     incorporator or stockholder of the Company or any Subsidiary Guarantor, as
     such, will have any liability for any obligations of the Company or any
     Subsidiary Guarantor under the Notes, any Subsidiary Guarantee or the
     Indenture or for any claim based on, in respect of, or by reason of, such
     obligations or their creation. Each Holder by accepting a Note waives and
     releases all such liability. The waiver and release are part of the
     consideration for the issuance of the Notes.

          (13) Authentication. This Note will not be valid until authenticated
     by the manual signature of the Trustee or an Authenticating Agent.
