deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of
outstanding Notes have authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall

Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no

the Company to protect the Company and the Trustee from any loss they may suffer if a Note is
replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in

     (b) A Note does not cease to be outstanding because the Company or one of its Affiliates holds
the Note, provided that in determining whether the Holders of the requisite principal amount of the
outstanding Notes have given or taken any request, demand, authorization, direction, notice,
consent, waiver or other action hereunder, Notes owned by the Company or any Affiliate of the
Company will be disregarded and deemed not to be outstanding, (it being understood that in
determining whether the Trustee is protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other action, only Notes which the Trustee
knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any
Affiliate of the Company.

     Section 2.06 . Temporary Notes. Until definitive Notes are ready for delivery, the Company

other variations determined to be appropriate by the Officer executing the temporary Notes, as
evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company
will cause definitive Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of
the temporary Notes at the office or agency of the Company designated for the purpose pursuant to
Section 4.02, without charge to the Holder. Upon surrender for cancellation of any temporary Notes
the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like
principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will be entitled to the same benefits under the
Indenture as definitive Notes.

     Section 2.07 . Cancellation. The Company at any time may deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes
previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the
Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or
payment. The Trustee will cancel all Notes surrendered for transfer, exchange, payment or
cancellation and dispose of them in accordance with its normal procedures or the written
instructions of the Company. The Company may not issue new Notes to replace Notes it has paid in
full or delivered to the Trustee for cancellation.

     Section 2.08 . CUSIP and CINS Numbers. The Company in issuing the Notes may use “CUSIP” and
“CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or
exchange or in Offers to Purchase as a convenience to Holders, the notice to 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 or Offer to Purchase. The Company will promptly
notify the Trustee of any change in the CUSIP or CINS numbers.

     Section 2.09 . Registration, Transfer and Exchange. (a) The Notes will be issued in
registered form only, without coupons, and the Company shall cause the Trustee to maintain a
register (the “Register”) of the Notes, for registering the record ownership of the Notes by the
Holders and transfers and exchanges of the Notes. Each Holder of a Note agrees to indemnify the
Company and the Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable
United States Federal or state securities law. The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any

36

 

restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest in any Note
(including any transfers between or among depositary participants or beneficial owners of interests
in any Global Note) other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly required by, the terms
of, this Indenture, and to examine the same to determine substantial compliance as to form with the
express requirements hereof.

     (b) (i) Each Global Note will be registered in the name of the Depositary or its nominee and,
so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

     (ii) Each Global Note will be delivered to the Trustee as custodian for the
Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be
limited to transfers thereof in whole, but not in part, to the Depositary, its successors
or their respective nominees, except (1) as set forth in Section 2.09(b)(iv) and (2)
transfers of portions thereof in the form of Certificated Notes may be made upon request
of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary procedures
of the Depositary and in compliance with this Section and Section 2.10.

     (iii) Agent Members will have no rights under the Indenture with respect to any Global
Note held on their behalf by the Depositary, and the Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing,
the Depositary or its nominee may grant proxies and otherwise authorize any Person
(including any Agent Member and any Person that holds a beneficial interest in a Global
Note through an Agent Member) to take any action which a Holder is entitled to take under
the Indenture or the Notes, and nothing herein will 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 security.

     (iv) If (x) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for a Global Note and a successor depositary is not appointed by
the Company within 90 days of the notice or (y) an Event of Default has occurred and is
continuing and the Trustee has received a request from the Depositary, the Trustee will
promptly exchange each beneficial interest in the Global Note for one or more Certificated
Notes in authorized denominations having an equal aggregate principal amount registered in
the name of the owner of such

37

 

beneficial interest, as identified to the Trustee by the
Depositary, and thereupon the Global Note will be deemed canceled. If such Note was an
Offshore Global Note, then the Certificated Notes issued in exchange therefor will not
bear the Restricted Legend.

     (c) Each Certificated Note will be registered in the name of the holder thereof or its
nominee.

     (d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or
exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized
denomination by presenting to the Trustee a written request therefor stating the name of the
proposed transferee or requesting such an exchange, accompanied by any certification, opinion or
other document required by Section 2.10. The Trustee will promptly register any transfer or
exchange that meets the requirements of this Section by noting the same in the register
maintained by the Trustee for the purpose; provided that

     (x) no transfer or exchange will be effective until it is registered in such register
and

     (y) the Trustee will not be required (i) to issue, register the transfer of or
exchange any Note for a period of 15 days before a selection of Notes to be redeemed or
purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange
any Note so selected for redemption or purchase in whole or in part, except, in the case
of a partial redemption or purchase, that portion of any Note not being redeemed or
purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to
occur after a Regular Record Date but on or before the corresponding Interest Payment
Date, to register the transfer of or exchange any Note on or after the Regular Record Date
and before the date of redemption or purchase. Prior to the registration of any transfer,
the Company, the Trustee and their agents will treat the Person in whose name the Note is
registered as the owner and Holder thereof for all purposes (whether or not the Note is
overdue), and will not be affected by notice to the contrary.

     From time to time the Company will execute and the Trustee will authenticate additional Notes
as necessary in order to permit the registration of a transfer or exchange in accordance with this
Section.

     No service charge will be imposed in connection with any transfer or exchange of any Note, but
the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection

38

 

therewith (other than a transfer tax or other similar
governmental charge payable upon exchange pursuant to subsection (b)(iv)).

     (e) (i) Global Note to Global Note. If a beneficial interest in a Global Note is transferred
or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a
decrease in the principal amount of the Global Note being transferred or exchanged equal to the
principal amount of such transfer or exchange and (y) record a like increase in the principal
amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to
a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an
interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such
Global Note and become an interest in the other Global Note and, accordingly, will thereafter be
subject to all transfer and exchange restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an interest.

     (ii) Global Note to Certificated Note. If a beneficial interest in a Global Note is
transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease
in the principal amount of such Global Note equal to the principal amount of such transfer
or exchange and (y) deliver one or more new Certificated Notes in authorized denominations
having an equal aggregate principal amount to the transferee (in the case of a transfer)
or the owner of such beneficial interest (in the case of an exchange), registered in the
name of such transferee or owner, as applicable.

     (iii) Certificated Note to Global Note. If a Certificated Note is transferred or
exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such
Certificated Note, (y) record an increase in the principal amount of such Global Note
equal to the principal amount of such transfer or exchange and (z) in the event that such
transfer or exchange involves less than the entire principal amount of the canceled
Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in
authorized denominations having an aggregate principal amount equal to the untransferred
or unexchanged portion of the canceled Certificated Note, registered in the name of the
Holder thereof.

     (iv) Certificated Note to Certificated Note. If a Certificated Note is transferred
or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated
Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in
authorized denominations having an aggregate principal amount equal to the principal
amount of such transfer or exchange to the transferee (in the case of a transfer) or the
Holder of the canceled Certificated Note (in the case of an exchange),

39

 

registered in the
name of such transferee or Holder, as applicable, and (z) if such transfer or exchange
involves less than the entire principal amount of the canceled Certificated Note, deliver
to the Holder thereof one or more Certificated Notes in authorized denominations having an
aggregate principal amount equal to the untransferred or unexchanged portion of the
canceled Certificated Note, registered in the name of the Holder thereof.

     Section 2.10 . Restrictions on Transfer and Exchange. (a) The transfer or exchange of any
Note (or a beneficial interest therein) may only be made in accordance with this Section and
Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable
rules and procedures of the Depositary. The Trustee shall refuse to register any requested
transfer or exchange that does not comply with the preceding sentence.

     (b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest
therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of
the type set forth opposite in column B below may
only be made in compliance with the certification requirements (if any) described in the
clause of this paragraph set forth opposite in column C below.

     (ii) The Person requesting the transfer or exchange must deliver or cause to be
delivered to the Trustee a duly completed Regulation S Certificate; provided that if the
requested transfer or exchange is made by the Holder of a Certificated Note that does not
bear the Restricted Legend, then no certification is required.

     (iii) The Person requesting the transfer or exchange must deliver or cause to be
delivered to the Trustee (x) a duly completed Rule 144A Certificate, (y) a duly completed
Regulation S Certificate or (z) a duly completed Institutional Accredited Investor
Certificate, and/or an Opinion of Counsel and such other certifications and evidence as
the

40

 

Company may reasonably require in order to determine that the proposed transfer or
exchange is being made in compliance with the Securities Act and any applicable securities
laws of any state of the United States; provided that if the requested transfer or
exchange is made by the Holder of a Certificated Note that does not bear the Restricted
Legend, then no certification is required. In the event that (i) the requested transfer
or exchange takes place after the Restricted Period and a duly completed Regulation S
Certificate is delivered to the Trustee or (ii) a Certificated Note that does not bear the
Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the
Trustee will deliver a Certificated Note that does not bear the Restricted Legend.

     (iv) The Person requesting the transfer or exchange must deliver or cause to be
delivered to the Trustee a duly completed Rule 144A Certificate.

     (v) If the requested transfer or exchange takes place during the Restricted Period,
the person requesting the transfer or exchange must deliver or cause to be delivered to
the Trustee (x) a duly completed Rule
144A Certificate or (y) a duly completed Institutional Accredited Investor
Certificate and/or an Opinion of Counsel and such other certifications and evidence as the
Company may reasonably require in order to determine that the proposed transfer or
exchange is being made in compliance with the Securities Act and any applicable securities
laws of any state of the United States. If the requested transfer or exchange takes place
after the Restricted Period, no certification is required and the Trustee will deliver a
Certificated Note that does not bear the Restricted Legend.

     (c) No certification is required in connection with any transfer or exchange of any Note (or a
beneficial interest therein)

     (i) after such Note is eligible for resale pursuant to Rule 144(k) under the
Securities Act (or a successor provision); provided that the Company has provided the
Trustee with an Officer’s Certificate to that effect, and the Company may require from any
Person requesting a transfer or exchange in reliance upon this clause (i) an opinion of
counsel and any other reasonable certifications and evidence in order to support such
certificate; or

     (ii) (x) sold pursuant to an effective registration statement, pursuant to the
Registration Rights Agreement or otherwise or (y) which is validly tendered for exchange
into an Exchange Note pursuant to an Exchange Offer.

41

 

     Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted
Legend.

     (d) The Trustee will retain copies of all certificates, opinions and other documents received
in connection with the transfer or exchange of a Note (or a beneficial interest therein), and the
Company will have the right to inspect and make copies thereof at any reasonable time upon written
notice to the Trustee.

     Section 3.01 . Optional Redemption. At any time and from time to time on or after January 1,
2012, the Company may redeem the Notes, in whole or in part, at a redemption price equal to the
percentage of principal amount set forth below plus accrued and unpaid interest and Additional
Interest thereon, if any, to the applicable redemption date, if redeemed during the twelve-month
period beginning on January 1 of the years indicated below.

	 	 	 	 	 
	Year	 	Percentage	 
	2012
	 	 	104.750	%
	2013
	 	 	103.167	%
	2014
	 	 	101.583	%
	2015 and thereafter
	 	 	100	%

     Section 3.02 . Redemption with Proceeds of Public Equity Offering. At any time and from time
to time prior to January 1, 2010, the Company may redeem the Notes with the net cash proceeds
received by the Company from any Public Equity Offering at a redemption price equal to 109.50% of
the principal amount plus accrued and unpaid interest to the redemption date, in an aggregate
principal amount for all such redemptions not to exceed 35% of the original aggregate principal
amount of the Notes issued (including Additional Notes), provided that

     (i) in each case the redemption takes place not later than 60 days after the closing
of the related Public Equity Offering, and

     (ii) not less than 65% of the aggregate principal amount of the Notes issued
(including Additional Notes) remains outstanding immediately thereafter.

     Section 3.03 . Method and Effect of Redemption. (a) If the Company elects to redeem Notes,
it must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed
by delivering an Officers’ Certificate at

42

 

least 60 days before the redemption date (unless a
shorter period is satisfactory to the Trustee). If fewer than all of the Notes are being redeemed,
the Officers’ Certificate must also specify a record date not less than 15 days after the date of
the notice of redemption is given to the Trustee, and the Trustee will select the Notes to be
redeemed pro rata, by lot or by any other method the Trustee in its sole discretion deems fair and
appropriate, in denominations of $1,000 in principal amount and any multiple of $1,000 in excess
thereof. The Trustee will notify the Company promptly of the Notes or portions of Notes to be
called for redemption. Notice of redemption must be sent by the Company or at the Company’s
request, by the Trustee in the name and at the expense of the Company, to Holders whose Notes are
to be redeemed at least 30 days but not more than 60 days before the redemption date.

     (b) The notice of redemption will identify the Notes to be redeemed and will include or state
the following:

     (i) the redemption date;

     (ii) the redemption price, including the portion thereof representing any accrued
interest;

     (iii) the place or places where Notes are to be surrendered for redemption;

     (iv) Notes called for redemption must be so surrendered in order to collect the
redemption price;

     (v) on the redemption date the redemption price will become due and payable on Notes
called for redemption, and interest on Notes called for redemption will cease to accrue on
and after the redemption date;

     (vi) if any Note is redeemed in part, on and after the redemption date, upon
surrender of such Note, new Notes equal in principal amount to the unredeemed portion will
be issued; and

     (vii) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the notice of redemption and that the Holder should rely only on the other
identification numbers printed on the Notes.

     (c) Once notice of redemption is sent to the Holders, Notes called for redemption become due
and payable at the redemption price on the redemption date, and upon surrender of the Notes called
for redemption, the Company shall

43

 

redeem such Notes at the redemption price. Commencing on the
redemption date, Notes redeemed will cease to accrue interest. Upon surrender of any Note redeemed
in part, the Holder will receive a new Note equal in principal amount to the unredeemed portion of
the surrendered Note.

     Section 3.04 . Offer to Purchase. (a) An “Offer to Purchase” means an offer by the Company
to purchase Notes as required by the Indenture. An Offer to Purchase must be made by written offer
(the “offer”) sent to the Holders. The Company will notify the Trustee at least 15 days (or such
shorter period as is acceptable to the Trustee) prior to sending the offer to Holders of its
obligation to make an Offer to Purchase, and the offer will be sent by the Company or, at the
Company’s request, by the Trustee in the name and at the expense of the Company.

     (b) The offer must include or state the following as to the terms of the Offer to Purchase:

     (i) the provision of the Indenture pursuant to which the Offer to Purchase is being
made;

     (ii) the aggregate principal amount of the outstanding Notes offered to be purchased
by the Company pursuant to the Offer to Purchase
(including, if less than 100%, the manner by which such amount has been determined
pursuant to the Indenture) (the “purchase amount”);

     (iii) the purchase price, including the portion thereof representing accrued
interest;

     (iv) an expiration date (the “expiration date”) not less than 30 days or more than 60
days after the date of the offer, and a settlement date for purchase (the “purchase date”)
not more than five Business Days after the expiration date;

     (v) information concerning the business of the Company and its Subsidiaries which the
Company in good faith believes will enable the Holders to make an informed decision with
respect to the Offer to Purchase, at a minimum to include

     (A) the most recent annual and quarterly financial statements and
“Management’s Discussion and Analysis of Financial Condition and Results of
Operations” for the Company,

     (B) a description of material developments in the Company’s business
subsequent to the date of the latest of the

44

 

financial statements (including a
description of the events requiring the Company to make the Offer to Purchase),
and

     (C) if applicable, appropriate pro forma financial information concerning
the Offer to Purchase and the events requiring the Company to make the Offer to
Purchase;

     (vi) a Holder may tender all or any portion of its Notes, subject to the requirement
that any portion of a Note tendered must be in a minimum denomination of $1,000 and any
multiple of $1,000 in excess thereof.

     (vii) the place or places where Notes are to be surrendered for tender pursuant to
the Offer to Purchase;

     (viii) each Holder electing to tender a Note pursuant to the offer will be required
to surrender such Note at the place or places specified in the offer prior to the close of
business on the expiration date (such Note being, if the Company or the Trustee so
requires, duly endorsed or accompanied by a duly executed written instrument of transfer);

     (ix) interest on any Note not tendered, or tendered but not purchased by the Company
pursuant to the Offer to Purchase, will continue to accrue;

     (x) on the purchase date the purchase price will become due and payable on each Note
accepted for purchase, and interest on Notes purchased will cease to accrue on and after
the purchase date;

     (xi) Holders are entitled to withdraw Notes tendered by giving notice, which must be
received by the Company or the Trustee not later than the close of business on the
expiration date, setting forth the name of the Holder, the principal amount of the
tendered Notes, the certificate number of the tendered Notes and a statement that the
Holder is withdrawing all or a portion of the tender;

     (xii) (A) if Notes in an aggregate principal amount less than or equal to the
purchase amount are duly tendered and not withdrawn pursuant to the Offer to Purchase, the
Company will purchase all such Notes, and (B) if the Offer to Purchase is for less than
all of the outstanding Notes and Notes in an aggregate principal amount in excess of the
purchase amount are tendered and not withdrawn pursuant to the offer, the Company will
purchase Notes having an aggregate principal amount equal to the purchase amount on a pro
rata basis, with adjustments so that

45

 

only Notes in denominations of $1,000 in principal
amount and any multiple of $1,000 in excess thereof will be purchased;

     (xiii) if any Note is purchased in part, new Notes equal in principal amount to the
unpurchased portion of the Note will be issued; and

     (xiv) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the offer and that the Holder should rely only on the other identification
numbers printed on the Notes.

     (c) On or prior to the purchase date, the Company will accept tendered Notes for purchase as
required by the Offer to Purchase and deliver to the Trustee all Notes so accepted together with an
Officers’ Certificate specifying which Notes have been accepted for purchase. On the purchase date
the purchase price will become due and payable on each Note accepted for purchase, and interest on
Notes purchased will cease to accrue on and after the purchase date. The Trustee will promptly
return to Holders any Notes not accepted for purchase and send to Holders new Notes equal in
principal amount to any unpurchased portion of any Notes accepted for purchase in part.

     (d) The Company will comply with Rule 14e-1 under the Exchange Act and all other applicable
laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary
to permit such compliance.

ARTICLE 4

Covenants

     Section 4.01 . Payment of Notes. (a) The Company agrees to pay the principal of and
interest on the Notes on the dates and in the manner provided in the Notes and the Indenture. Not
later than 10:00 A.M. (New York City time) on the due date of any principal of or interest on any
Notes, or any redemption or purchase price of the Notes, the Company will deposit with the Trustee
(or Paying Agent) money in immediately available funds sufficient to pay such amounts, provided
that if the Company or any Affiliate of the Company is acting as Paying Agent, it will, on or
before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a
sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as
provided in the Indenture. In each case the Company will promptly notify the Trustee of its
compliance with this paragraph.

46

 

     (b) An installment of principal or interest will be considered paid on the date due if the
Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds on that
date money designated for and sufficient to pay the installment. If the Company or any Affiliate
of the Company acts as Paying Agent, an installment of principal or interest will be considered
paid on the due date only if paid to the Holders.

     (c) The Company agrees to pay interest on overdue principal, and, to the extent lawful,
overdue installments of interest at the rate per annum specified in the Notes.

     (d) Payments in respect of the Notes represented by the Global Notes are to be made by wire
transfer of immediately available funds to the accounts specified by the Holders of the Global
Notes. With respect to Certificated Notes, the Company will make all payments by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or, if no such account
is specified, by mailing a check to each Holder’s registered address.

     Section 4.02 . Maintenance of Office or Agency. The Company will maintain in the United
States of America, an office or agency where Notes may be surrendered for registration of transfer
or exchange or for presentation for payment and where notices and demands to or upon the Company in
respect of the Notes and the Indenture may be served. The Company hereby initially designates the
Corporate Trust Office of the Trustee as such office of the Company. The Company will 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 to the Trustee.

     The Company may also from time to time designate one or more other offices or agencies where
the Notes may be surrendered or presented for any of such purposes and may from time to time
rescind such designations. The Company will 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 . Existence. The Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with their respective organizational documents, and the
material rights, licenses and franchises of the Company and each Restricted Subsidiary, provided
that the Company is not required to preserve any such right, license or franchise, or the existence
of any Restricted Subsidiary, if the maintenance or preservation thereof is no longer desirable in
the conduct of the business of the Company and its Restricted

47

 

Subsidiaries taken as a whole; and
provided further that this Section does not prohibit any transaction otherwise permitted by Section
4.13 or Article 5.

     Section 4.04 . Payment of Taxes and other Claims. The Company will pay or discharge, and
cause each of its Subsidiaries to pay or discharge before the same become delinquent (i) all
material taxes, assessments and governmental charges levied or imposed upon the Company or any
Subsidiary or its income or profits or property, and (ii) all material lawful claims for labor,
materials and supplies that, if unpaid, might by law become a Lien upon the property of the Company
or any Subsidiary, other than any such tax, assessment, charge or claim the amount, applicability
or validity of which is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established.

     Section 4.05 . Maintenance of Properties and Insurance. (a) The Company will cause all
properties used or useful in the conduct of its business or the business of any of its Restricted
Subsidiaries to be maintained and kept in good condition, repair and working order as in the
judgment of the Company may be necessary so that the business of the Company and its Restricted
Subsidiaries may be properly and advantageously conducted at all times; provided that nothing in
this Section prevents the Company or any Restricted Subsidiary from discontinuing the use,
operation or maintenance of any of such properties or disposing of any of them, if such
discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of the
business of the Company and its Restricted Subsidiaries taken as a whole.

     (b) The Company will provide or cause to be provided, for itself and its Restricted
Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds
customarily insured against by corporations similarly situated and owning like properties,
including, but not limited to, products liability insurance and public liability insurance, with
reputable insurers, in such amounts, with such deductibles and by such methods as are customary for
corporations similarly situated in the industry in which the Company and its Restricted
Subsidiaries are then conducting business.

     Section 4.06 . Limitation on Debt and Disqualified or Preferred Stock. (a) The Company

     (i) will not, and will not permit any of its Restricted Subsidiaries to, Incur any
Debt; and

     (ii) will not, and will not permit any Restricted Subsidiary to, Incur any
Disqualified Stock, and will not permit any of its Restricted Subsidiaries to Incur any
Preferred Stock (other than Disqualified or

48

 

Preferred Stock of Restricted Subsidiaries
held by the Company or a Wholly Owned Restricted Subsidiary, so long as it is so held);

provided that the Company or any Guarantor may Incur Debt or Disqualified Stock if, on the date of
the Incurrence, after giving effect to the Incurrence and the receipt and application of the
proceeds therefrom, the Fixed Charge Coverage Ratio is not less than 2.00 to 1.00.

     (b) Notwithstanding the foregoing, the Company and, to the extent provided below, any
Restricted Subsidiary may Incur the following (“Permitted Debt”):

     (i) Debt (“Permitted Bank Debt”) of the Company pursuant to the Credit Agreement;
provided that the aggregate principal amount of such Debt at any time outstanding does not
exceed the greater of (x) $110 million, and (y) the Borrowing Base Amount, and Guarantees
of such Debt by any Restricted Subsidiary;

     (ii) Debt of the Company or any Restricted Subsidiary to the Company or any
Restricted Subsidiary so long as such Debt continues to be owed to the Company or a
Restricted Subsidiary and which, if the obligor is the Company or a Guarantor, is
subordinated in right of payment to the Notes;

     (iii) Debt of the Company pursuant to the Notes (other than Additional Notes) and the
New Senior Subordinated Notes due 2013 and Debt of any Guarantor pursuant to a Note
Guaranty of the Notes (including Additional Notes) and any guarantee of the New Senior
Subordinated Notes due 2013;

     (iv) Debt (“Permitted Refinancing Debt”) constituting an extension or renewal of,
replacement of, or substitution for, or issued in exchange for, or the net proceeds of
which are used to repay, redeem, repurchase, refinance or refund, including by way of
defeasance (all of the
above, for purposes of this clause, “refinance”) then outstanding Debt in an amount
not to exceed the principal amount of the Debt so refinanced, plus premiums, fees and
expenses; provided that

     (A) in case the Debt to be refinanced is subordinated in right of payment
to the Notes, the new Debt, by its terms or by the terms of any agreement or
instrument pursuant to which it is outstanding, is expressly made subordinate in
right of payment to the Notes at least to the extent that the Debt to be
refinanced is subordinated to the Notes,

     (viii) Debt of the Company or any Restricted Subsidiary outstanding on the Issue Date
(and, for purposes of clause (iv)(D), not otherwise constituting Permitted Debt);

meets the criteria of more than one of the categories of Permitted Debt described in clauses (i)
through (xiii) above or is entitled to be Incurred pursuant to paragraph (a) of this Section 4.06,

substantially identical terms.

     Section 4.07 . Limitation on Restricted Payments. (a) The Company will not, and will not
permit any Restricted Subsidiary to, directly or indirectly (the payments and other actions
described in the following clauses being collectively “Restricted Payments”):

     (i) declare or pay any dividend or make any distribution on its Equity Interests

previously deferred pursuant to clause (a)) or principal at Stated Maturity; or

     (iv) make any Investment other than a Permitted Investment;

     (1) no Default has occurred and is continuing,

     (2) the Company could Incur at least $1.00 of Debt under the Fixed Charge Coverage
Ratio test set forth in Section 4.06(a), and

     (3) the aggregate amount expended for all Restricted Payments made on or after the
Issue Date would not, subject to paragraph (c), exceed the sum of

     (A) 50% of the aggregate amount of the Consolidated Net Income (or, if the
Consolidated Net Income is a loss, minus 100% of the amount of the loss) accrued
on a cumulative basis during the period, taken as one accounting period,
beginning on the first day of the first fiscal quarter of the Company for which
a quarterly or annual report is provided pursuant to Section 4.17 after the

fiscal quarter for which internal financial statements are available, plus

     (B) subject to paragraph (c), the aggregate net cash proceeds received by
the Company (other than from a Subsidiary) after the Issue Date from

     (1) the issuance and sale of its Qualified Equity Interests,
including by way of issuance of its

52

 

Disqualified Equity Interests or
Debt to the extent since converted into Qualified Equity Interests of
the Company, or

     (2) as a contribution to its common equity, plus

     (C) an amount equal to the sum, for all Unrestricted Subsidiaries, of the
following:

   (x) the cash return, after the Issue Date, on Investments in an
Unrestricted Subsidiary made after the Issue Date pursuant to this
paragraph (a) as a result of any sale for cash, repayment, redemption,
liquidating distribution or other cash realization (not included in
Consolidated Net Income), plus

   (y) the portion (proportionate to the Company’s equity interest in
such Subsidiary) of the fair market value of the assets less liabilities
of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary
is designated a Restricted Subsidiary,

not to exceed, in the case of any Unrestricted Subsidiary, the amount of
Investments made after the Issue Date by the Company and its Restricted
Subsidiaries in such Unrestricted Subsidiary pursuant to this paragraph (a), plus

     (D) the cash return, after the Issue Date, on any other Investment made
after the Issue Date pursuant to this paragraph (a), as a result of any sale for
cash, repayment, redemption, liquidating distribution or other cash realization
(not included in Consolidated Net Income), not to exceed the amount of such
Investment so made.

     The amount expended in any Restricted Payment, if other than in cash, will be deemed to be the
fair market value of the relevant non-cash assets, as determined in good faith by the Board of
Directors, whose determination will be conclusive and evidenced by a Board Resolution.

     (b) The foregoing will not prohibit:

     (i) the payment of any dividend within 60 days after the date of declaration thereof
if, at the date of declaration, such payment would comply with paragraph (a);

53

 

     (ii) dividends or distributions by a Restricted Subsidiary payable, on a pro rata
basis or on a basis more favorable to the Company, to all holders of any class of Capital
Stock of such Restricted Subsidiary a majority of which is held, directly or indirectly
through Restricted Subsidiaries, by the Company;

     (iii) the repayment, redemption, repurchase, defeasance or other acquisition or
retirement for value of all or any portion of the Company’s 13% Senior Subordinated Notes

     (iv) the repayment, redemption, repurchase, defeasance or other acquisition or
retirement for value of Subordinated Debt with the proceeds of, or in exchange for,
Permitted Refinancing Debt, or, in the case of the New Senior Subordinated Notes due 2013,
proceeds of, or in exchange for, Permitted Refinancing Debt (or Debt that would be
Permitted Refinancing Debt except that it is senior unsecured Debt and therefore would not
comply with clause (A) of the definition thereof);

     (v) the purchase, redemption or other acquisition or retirement for value of Equity
Interests of the Company or any Restricted Subsidiary in exchange for, or out of the
proceeds of a substantially concurrent offering of, Qualified Equity Interests of the
Company or of a cash contribution to the common equity of the Company;

     (vi) the repayment, redemption, repurchase, defeasance or other acquisition or
retirement of Subordinated Debt of the Company in exchange for, or out of the proceeds of,
a substantially concurrent offering of, Qualified Equity Interests of the Company or of a

former officers, directors or employees
(or their estates or beneficiaries under their estates), upon death, disability,
retirement, severance or termination of employment or pursuant to any agreement under
which the Equity Interests were issued; provided that the aggregate cash consideration
paid therefor after the Issue Date does not

54

 

exceed an aggregate amount of $1,000,000 in
any fiscal year (with unused amounts in any fiscal year being permitted to be carried over
for the two succeeding fiscal years);

     (ix) the payment of cash dividends on any Disqualified Stock of the Company or a
Restricted Subsidiary or Preferred Stock of a Restricted Subsidiary Incurred after the
Issue Date in compliance with Section 4.06;

     (x) the repurchase of any Subordinated Debt at a purchase price not greater than 101%
of the principal amount thereof in the event of (x) a change of control pursuant to a
provision no more favorable to the holders thereof than Section 4.12 or (y) an Asset Sale
pursuant to a provision no more favorable to the holders thereof than Section 4.13,
provided that, in each case, prior to the repurchase the Company has made an Offer to
Purchase and repurchased all Notes issued under the Indenture that were validly tendered
for payment in connection with the Offer to Purchase;

     (xi) the payment of a dividend or distribution by the Company and its Subsidiaries,
directly or indirectly, to ACP Holding in an amount sufficient to permit ACP Holding to
pay its consolidated, combined or unitary United States federal, state and local tax
liabilities relating to the business of the Company and its Subsidiaries, provided that
ACP Holding applies the amount of such dividend or distribution for such purpose at
approximately such time;

     (xii) payments by the Company to NFC Castings or ACP Holding not to exceed an amount
necessary to permit NFC Castings or ACP Holding to (A) make payments in respect to its
indemnification obligations owing to directors, officers, or other Persons under NFC
Castings’ or ACP Holding’s charter or by-laws or pursuant to written agreements with any
such Person, (B) make payments in respect of its other operational expenses (other than
taxes) incurred in the ordinary course of business to the extent related to acting as a
holding company for the Company, or (C) make payments in respect of indemnification
obligations and costs and expenses incurred by ACP Holding in connection with any offering
of common stock of ACP Holding; and

     (xiii) any other Restricted Payment, which together with all other Restricted
Payments made pursuant to this clause (xiii) on or after the Issue Date, does not exceed
$10.0 million; provided, however, that no Restricted Payments may be made pursuant to this
clause (xiii) in order to
repay, redeem, repurchase, defease or otherwise acquire or retire for value,

55

 

or make
any payment on or with respect to, the New Senior Subordinated Notes due 2013; and

provided that, in the case of clauses (vii), (viii), (ix), (xii) or (xiii), no Default has occurred
and is continuing or would occur as a result thereof.

     (c) Proceeds of the issuance of Qualified Equity Interests will be included under clause (iii)
of paragraph (a) only to the extent they are not applied as described in clause (v), (vi) or (vii)
of paragraph (b). Restricted Payments permitted pursuant to clause (iv), (v), (vi), (vii) or (xi)
of paragraph (b) will not be included in making the calculations under clause (iii) of paragraph
(a).

     (d) Not later than the date of making any Restricted Payment, the Company will deliver to the
Trustee an Officers’ Certificate stating that the Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant were calculated, which calculations
may be based on the Company’s latest available financial statements, delivered, or required to be
delivered, pursuant to Section 4.17.

     Section 4.08 . Limitation on Liens. The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, incur or permit to exist any Lien of any nature whatsoever
on any of its properties or assets, whether owned at the Issue Date or thereafter acquired, other
than Permitted Liens.

     Section 4.09 . Limitation on Sale and Leaseback Transactions. The Company will not, and will

     (a) the Company or the Restricted Subsidiary would be entitled to

     (i) Incur Debt in an amount equal to the Attributable Debt with respect to such Sale
and Leaseback Transaction pursuant to Section 4.06, and

     (ii) create a Lien on such property or asset securing such Attributable Debt pursuant
to Section 4.08,

in which case, the corresponding Debt and Lien will be deemed incurred pursuant to those
provisions, and

     (b) the Company complies with Section 4.13 in respect of such transaction.

     Section 4.10 . Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. (a) Except as provided in paragraph (b), the

56

 

Company will not, and will not permit
any Restricted Subsidiary to, create or
otherwise cause or permit to exist or become effective any consensual encumbrance or
restriction of any kind on the ability of any Restricted Subsidiary to

     (i) pay dividends or make any other distributions on any Equity Interests of the
Restricted Subsidiary owned by the Company or any other Restricted Subsidiary,

     (ii) pay any Debt or other obligation owed to the Company or any other Restricted
Subsidiary,

     (b) The provisions of paragraph (a) do not apply to any encumbrances or restrictions

     (i) existing on the Issue Date in the Credit Agreement, the Indenture, the Security
Documents or any other agreements in effect on the Issue Date, and any extensions,
renewals, replacements or refinancings of any of the foregoing; provided that the
encumbrances and restrictions in the extension, renewal, replacement or refinancing are,
taken as a whole, no less favorable in any material respect to the Noteholders than the
encumbrances or restrictions being extended, renewed, replaced or refinanced;

     (ii) existing under or by reason of applicable law;

     (iii) existing

     (A) with respect to any Person, or to the property or assets of any Person,
at the time the Person is acquired by the Company or any Restricted Subsidiary,
or

     (B) with respect to any Unrestricted Subsidiary at the time it is
designated or is deemed to become a Restricted Subsidiary,

which encumbrances or restrictions (1) are not applicable to any other Person or the
property or assets of any other Person and (2) were not put in place in anticipation of
such event and any extensions, renewals,

57

 

replacements or refinancings of any of the
foregoing, provided the encumbrances and restrictions in the extension, renewal,
replacement or refinancing are, taken as a whole, no less favorable in any material
respect
to the Noteholders than the encumbrances or restrictions being extended, renewed, replaced
or refinanced;

     (iv) of the type described in clause (a)(iv) arising or agreed to in the ordinary
course of business (A) that restrict in a customary manner the subletting, assignment or
transfer of any property or asset that is subject to a lease or license or (B) by virtue
of any Lien on, or agreement to transfer, option or similar right with respect to any
property or assets of, the Company or any Restricted Subsidiary;

     (v) with respect to a Restricted Subsidiary and imposed pursuant to an agreement that

Capital Stock of, or property and assets of, the Restricted Subsidiary that is permitted
by Section 4.13;

     (vi) contained in the terms governing any Permitted Refinancing Debt, which terms
are, taken as a whole, no less favorable in any material respect to the Noteholders than
those contained in the agreements governing the Debt being refinanced, or

     (vii) required pursuant to the Indenture.

     Section 4.11 . Guaranties by Restricted Subsidiaries. If the Company or any of its
Restricted Subsidiaries acquires or creates a Wholly Owned Domestic Restricted Subsidiary after the
date of the Indenture or acquires or creates any other Restricted Subsidiary and such Restricted
Subsidiary guarantees any other Debt of the Company, the new Restricted Subsidiary must provide a
Note Guaranty and become a party to the Security Documents (and pledge its assets to the extent
they would constitute Collateral pursuant to Section 11.01(b)).

     A Restricted Subsidiary required to provide a Note Guaranty shall execute a supplemental
indenture substantially in the form of Exhibit B, and deliver an Opinion of Counsel to the Trustee
to the effect that the supplemental indenture has been duly authorized, executed and delivered by
the Restricted Subsidiary and constitutes a valid and binding obligation of the Restricted
Subsidiary, enforceable against the Restricted Subsidiary in accordance with its terms (subject to
customary exceptions).

     Section 4.12 . Repurchase of Notes Upon a Change of Control. Not later than 30 days
following a Change of Control, the Company will make an Offer to

58

 

Purchase all outstanding Notes at
a purchase price equal to 101% of the principal amount plus accrued interest to the date of
purchase.

     Section 4.13 . Limitation on Asset Sales. The Company will not, and will not permit any
Restricted Subsidiary to, make any Asset Sale unless the following conditions are met:

     (a) The Asset Sale is for fair market value, as determined in good faith by the Board of
Directors.

     (b) At least 75% of the consideration received by the Company or such Restricted Subsidiary
consists of cash received at closing (except in the case of a Permitted Asset Swap); provided
however, to the extent that any disposition in such Asset Sale (including in the case of a
Permitted Asset Swap) was of Primary Collateral, the non-cash consideration received is pledged as
Primary Collateral under the Security Documents substantially simultaneously with such sale, in
accordance with the requirements set forth in Section 11.01(b).

For purposes of this clause (b): the assumption by the purchaser of Debt or other obligations
(other than Subordinated Debt) of the Company or a Restricted Subsidiary pursuant to a customary
novation agreement (unless and to the extent that the assets disposed of in such Asset Sale are
Primary Collateral), and instruments or securities received from the purchaser that are promptly,
but in any event within 60 days of the closing, converted by the Company to cash, to the extent of
the cash actually so received, shall be considered cash received at closing.

     (c) Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Net
Cash Proceeds may be used

     (i) unless the disposition was of Primary Collateral, to repay Debt under the Credit
Agreement in each case owing to a Person other than the Company or any Restricted
Subsidiary, or

     (ii) to acquire all or substantially all of the assets of a Permitted Business, or a
majority of the Voting Stock of another Person that thereupon becomes a Restricted
Subsidiary engaged in a Permitted Business, or to make capital expenditures or otherwise
acquire long-term assets that are to be used in a Permitted Business; provided that the
assets (including Voting Stock) acquired with the Net Cash Proceeds of a disposition of
Primary Collateral are pledged as Primary Collateral under the Security Documents
substantially simultaneously with such acquisition in accordance with the requirements of
the Indenture and provided further, that, in the case of this clause (ii), a binding
commitment shall be treated

59

 

as a permitted application of the Net Cash Proceeds from the
date of such commitment if (x) such acquisition or capital expenditure is consummated
within 545 days after receipt by the Company or any Restricted Subsidiary of the Net Cash
Proceeds of any Asset Sale and (y) if such acquisition or capital expenditure is not
consummated within the period set forth in subclause (x), the Net Cash Proceeds not so
applied will be deemed to be Excess Proceeds (as defined below);

     (d) The Net Cash Proceeds of an Asset Sale not applied pursuant to clause (c) within the time
periods specified therein constitute “Excess Proceeds”. Excess Proceeds of less than $10.0 million
will be carried forward and accumulated. When accumulated Excess Proceeds equals or exceeds $10.0
million, the Company must, within 30 days, make an Offer to Purchase Notes having a principal
amount equal to

     (i) accumulated Excess Proceeds, multiplied by

     (ii) a fraction (x) the numerator of which is equal to the outstanding principal
amount of the Notes and (y) the denominator of which is equal to the outstanding principal
amount of the Notes and all pari passu Debt that is also secured by Collateral on the same
basis as the Notes and similarly required to be repaid, redeemed or tendered for in
connection with the Asset Sale,

rounded down to the nearest $1,000. The purchase price for the Notes will be 100% of the principal
amount plus accrued interest to the date of purchase. Upon completion of the Offer to Purchase,
Excess Proceeds will be reset at zero, and any Excess Proceeds remaining after consummation of the
Offer to Purchase may be used for any purpose not otherwise prohibited by the Indenture.

     (e) To the extent that any Net Cash Proceeds are from a disposition of Primary Collateral the
fair market value of which exceeds $2.5 million in the aggregate, such Net Cash Proceeds will be
deposited with the Collateral Agent or the Trustee, as the case may be, and held as Collateral in
the Cash Collateral Account pending application pursuant to clause (c) or (d) above, and, in the
case of clause (d), released to the Company or the relevant Guarantor if remaining after
consummation of the Offer to Purchase.

     Section 4.14 . Limitation on Transactions with Affiliates. (a) The Company will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, enter into, renew or extend
any transaction or arrangement including the purchase, sale, lease or exchange of property or
assets, or the rendering of any service with any Affiliate of the Company or any Restricted
Subsidiary (a “Related Party Transaction”), except upon fair and reasonable terms no less

60

 

favorable
to the Company or the Restricted Subsidiary than could be obtained in a comparable arm’s-length
transaction with a Person that is not an Affiliate of the Company.

     (b) Any Related Party Transaction or series of Related Party Transactions with an aggregate
value in excess of $5.0 million must first be approved by a majority of the Board of Directors who
are disinterested in the subject matter of the transaction pursuant to a Board Resolution delivered
to the Trustee. Prior to entering into any Related Party Transaction or series of Related Party
Transactions with an aggregate value in excess of $15.0 million, the
Company must in addition obtain and deliver to the Trustee a favorable written opinion from a
nationally recognized investment banking firm as to the fairness of the transaction to the Company
and its Restricted Subsidiaries from a financial point of view.

     (c) The foregoing paragraphs do not apply to

     (i) any transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries of the Company and any merger of the Company and any
direct or indirect parent of the Company; provided, however, that such parent shall have
no material liabilities and no material assets other than cash, Cash Equivalents and the
Capital Stock of the Company or intermediate parent companies (which themselves have no
other material assets or liabilities) and such merger is otherwise in compliance with the
terms of the Indenture and effected for a bona fide business purpose;

     (ii) any reasonable fees, advances and compensation (including incentive
compensation) provided to, and indemnity provided on behalf of, officers, directors and
employees of NFC Castings, ACP Holding, the Company and its Restricted Subsidiaries as
determined in good faith by the Board of Directors of the Company;

     (iii) any Restricted Payments of a type described in paragraphs (a)(i) and (a)(ii)
under Section 4.07 if permitted by that covenant;

     (iv) transactions or payments pursuant to any employee, officer or director
compensation or benefit plans or arrangements entered into in the ordinary course of
business;

     (v) transactions pursuant to any contract or agreement in effect on the date of the
Indenture, as amended, modified or replaced from time to time so long as the amended,
modified or new agreements, taken as a

61

 

whole, are no less favorable to the Company and its
Restricted Subsidiaries than those in effect on the date of the Indenture;

     (vi) payment of principal of, and interest on, the Notes held by Affiliates;

     (vii) Debt permitted pursuant to paragraph (b)(ii) under Section 4.06;

     (viii) non-exclusive licenses of intellectual property among the Company and the
Restricted Subsidiaries or among the Restricted Subsidiaries;

     (ix) repurchases of the Company’s outstanding 13% Senior Subordinated Notes due 2013
and 11% Senior Secured Notes due 2010 owned by any Permitted Holders on the same terms and
conditions as repurchases from other holders thereof, including payment of all related
premiums and consent fees;

     (x) any redemption of the New Senior Subordinated Notes due 2013 at a price not
greater than 100% of the principal amount thereof, provided that any such redemption is
permitted under Section 4.07; or

     (xi) any transaction or series of related transactions with any customer or supplier
in the ordinary course of business that are on terms no less favorable than could be
obtained in a comparable arms-length transaction with a Person that is not an Affiliate of
the Company, which transaction or series of transactions, if their aggregate value exceeds
$5.0 million, are approved by a majority of the Board of Directors who are disinterested
in the subject matter thereof.

     Section 4.15 . Line of Business. The Company will not, and will not permit any of its
Restricted Subsidiaries, to engage in any business other than a Permitted Business, except to an
extent that so doing would not be material to the Company and its Restricted Subsidiaries, taken as
a whole.

     Section 4.16 . Designation of Restricted and Unrestricted Subsidiaries. (a) The Board of
Directors may designate any Subsidiary (including a newly acquired or created Subsidiary), other
than any entity that owns or operates the facilities that are owned or operated on the Issue Date
by the Neenah Foundry Company (but only with respect to the manufacturing facilities located in
Neenah, Wisconsin), the Dalton Corporation or Deeter Foundry, Inc., to be an Unrestricted
Subsidiary if it meets the following qualifications and the designation would not cause a Default.

62

 

     (i) Such Subsidiary does not own any Capital Stock of the Company or any Restricted
Subsidiary or hold any Debt of, or any Lien on any property of, the Company or any
Restricted Subsidiary.

     (ii) At the time of designation, the designation would be permitted under Section
4.07.

     (iii) To the extent the Debt of the Subsidiary is not Non-Recourse Debt, any
Guarantee or other credit support thereof by the Company or any Restricted Subsidiary is
permitted under Sections 4.06 and 4.07.

     (iv) The Subsidiary is not party to any transaction or arrangement with the Company
or any Restricted Subsidiary that would not be permitted under Section 4.14.

     (v) Neither the Company nor any Restricted Subsidiary has any obligation to subscribe
for additional Equity Interests of the Subsidiary or to maintain or preserve its financial
condition or cause it to achieve specified levels of operating results, except to the
extent permitted by Sections 4.06 and 4.07.

Once so designated the Subsidiary will remain an Unrestricted Subsidiary, subject to paragraph (b).

     (b) (i) A Subsidiary previously designated an Unrestricted Subsidiary which fails to meet the
qualifications set forth in paragraph (a) will be deemed to become at that time a Restricted
Subsidiary, subject to the consequences set forth in paragraph (d).

     (ii) The Board of Directors may designate an Unrestricted Subsidiary to be a
Restricted Subsidiary if the designation would not cause a Default.

     (c) Upon a Restricted Subsidiary becoming an Unrestricted Subsidiary,

     (i) all existing Investments of the Company and the Restricted Subsidiaries therein
(valued at the Company’s proportional share of the fair market value of its assets less
liabilities) will be deemed made at that time;

     (ii) all existing Capital Stock or Debt of the Company or a Restricted Subsidiary
held by it will be deemed Incurred at that time, and all Liens on property of the Company
or a Restricted Subsidiary held by it will be deemed incurred at that time;

63

 

     (iii) all existing transactions between it and the Company or any Restricted
Subsidiary will be deemed entered into at that time;

     (iv) it is released at that time from its Note Guaranty, if any, and any Liens
granted by such Restricted Subsidiary will also be released; and

     (v) it will cease to be subject to the provisions of the Indenture as a Restricted
Subsidiary.

     (d) Upon an Unrestricted Subsidiary becoming, or being deemed to become, a Restricted
Subsidiary,

the continued perfection of the liens of the Security Documents on the Collateral, to the extent
required by Section 314(b)(2) of the Trust Indenture Act.

     Section 4.19 . Impairment Of Security Interest; Further Assurances; Collateral Inspections
and Reports; Costs and Indemnification.

     (a) Neither the Company nor any of its Restricted Subsidiaries will take any action, or
knowingly or negligently omit to take any action, which action or omission might or would have the

Subsidiaries having an outstanding principal amount of $15.0 million or more in the aggregate for
all such Debt of all such Persons (i) an event of default that results in such Debt being due and
payable prior to its scheduled maturity or (ii) failure to make a principal payment when due and
such defaulted payment is not made, waived or extended within the applicable grace period;

     (f) one or more final judgments or orders for the payment of money are rendered against the
Company or any of its Significant Restricted Subsidiaries and are not paid or discharged, and there
is a period of 60 consecutive days following entry of the final judgment or order that causes the
aggregate amount for all such final judgments or orders outstanding and not paid or discharged
against all such Persons to exceed $15.0 million (in excess of amounts which the Company’s
insurance carriers have agreed to pay under applicable policies) during which a stay of
enforcement, by reason of a pending appeal or otherwise, is not in effect;

     (g) an involuntary case or other proceeding is commenced against the Company or any
Significant Restricted Subsidiary with respect to it or its debts under any bankruptcy, insolvency

with respect to the Company, occurs and is continuing under the Indenture, the Trustee or the
Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written
notice to the Company (and to the Trustee if the notice is given by the Holders), may, and the
Trustee at the request of such Holders shall, declare the principal of and accrued interest on the
Notes to be immediately due and payable. Upon a declaration of acceleration, such principal and
interest will become immediately due and payable. If a bankruptcy default occurs with respect to
the Company, the principal of and accrued interest on the Notes then outstanding will become
immediately due and payable without any declaration or other act on the part of the Trustee or any
Holder.

     (b) The Holders of a majority in principal amount of the outstanding Notes by written notice
to the Company and to the Trustee may waive all past defaults and rescind and annul a declaration
of acceleration and its consequences if

71

premium, if any, and interest on the Notes that have become due solely by the declaration
of acceleration, have been cured or waived, and

may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding
at law or in equity to collect the payment of principal of and interest on the Notes or to enforce
the performance of any provision of the Notes or the Indenture. The Trustee may maintain a
proceeding even if it does not possess any of the Notes or does not produce any of them in the
proceeding.

     Section 6.04 . Waiver of Past Defaults. Except as otherwise provided in Sections 6.02, 6.07
and 9.02, the Holders of a majority in principal amount of the outstanding Notes may, by notice to
the Trustee, waive an existing Default and its consequences. Upon such waiver, the Default will
cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but
no such waiver will extend to any subsequent or other Default or impair any right consequent
thereon.

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

     Section 6.06 . Limitation on Suits. A Holder may not institute any proceeding, judicial or
otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under the Indenture or the Notes, unless:

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

     (b) Holders of at least 25% in aggregate principal amount of outstanding Notes have made
written request to the Trustee to institute

72

 

proceedings in respect of the Event of Default in its
own name as Trustee under the Indenture;

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

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

     (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the
outstanding Notes have not given the Trustee a direction that is inconsistent with such written
request.

     Section 6.07 . Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive payment of principal of or interest on its
Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such
payment on or after such respective dates, may not be impaired or affected without the consent of
that Holder.

     Section 6.08 . Collection Suit by Trustee. If an Event of Default in payment of principal or
interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust for the whole amount of
principal and accrued interest remaining unpaid, together with interest on overdue principal and,
to the extent lawful, overdue installments of interest, in each case at the rate specified in the
Notes, and such further amount as is sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel and any other amounts due the Trustee hereunder.

     Section 6.09 . Trustee May File Proofs of Claim. The Trustee may file proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders
allowed in any judicial proceedings relating to the Company or any Guarantor or their respective
creditors or property, and is entitled and empowered to collect, receive and distribute any money,
securities or other property payable or deliverable upon conversion or exchange of the Notes or
upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder to make
such payments to the Trustee and, if the Trustee consents to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it

73

 

for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts
due the Trustee hereunder. Nothing in the Indenture will be deemed to empower the Trustee to
authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or
to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

     Section 6.10 . Priorities. If the Trustee collects any money pursuant to this Article or
receives any money from the Collateral Agent upon foreclosure and sale of any Collateral, it shall
pay out the money in the following order:

     First: to the Trustee for all amounts due hereunder;

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

     Third: to the Company or as a court of competent jurisdiction may direct.

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

     Section 6.11 . Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, any Guarantors,
the Trustee and the Holders will be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Company, any
Guarantors, the Trustee and the Holders will continue as though no such proceeding had been
instituted.

     Section 6.12 . Undertaking for Costs. In any suit for the enforcement of any right or remedy
under the Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an
undertaking to pay the costs of the suit, and the court may assess reasonable costs, including
reasonable attorneys fees and expenses, against any party litigant (other than the Trustee) in the
suit having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by a Holder to enforce payment of

74

 

principal of or
interest on any Note on the respective due dates, or a suit by Holders of more than 10% in
principal amount of the outstanding Notes.

     Section 6.13 . Rights and Remedies Cumulative. No right or remedy conferred or reserved to
the Trustee or to the Holders under this Indenture is intended to be exclusive of any other right
or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in
addition to every other right and remedy hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not
prevent the concurrent assertion or exercise of any other right or remedy.

     Section 6.14 . Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder to exercise any right or remedy accruing upon any Event of Default will impair any such
right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

     Section 6.15 . Waiver of Stay, Extension or Usury Laws. The Company and each Guarantor
covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension
law or any usury law or other law that would prohibit or forgive the Company or the Guarantor from
paying all or any portion of the principal of, or interest on the Notes as contemplated herein,
wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the
performance of the Indenture. The Company and each Guarantor hereby expressly waives, to the
extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

The Trustee

     Section 7.01 . General. (a) The duties and responsibilities of the Trustee are as provided
by the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every
provision of the Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee is subject to this Article.

75

 

     (b) Except during the continuance of an Event of Default, the Trustee need perform only those
duties that are specifically set forth in the Indenture and no others, and no implied covenants or
obligations will be read into the Indenture against the Trustee. In case an Event of Default has
occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the
Indenture, and use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     (c) No provision of the Indenture shall be construed to relieve the Trustee from liability for
its own negligent action, its own negligent failure to act or its own willful misconduct.

     Section 7.02 . Certain Rights of Trustee. Subject to Trust Indenture Act Sections 315(a)
through (d):

     (a) The Trustee may conclusively rely, and will be fully protected in acting or refraining
from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the document, but, in the
case of any document which is specifically required to be furnished to the Trustee pursuant to any
provision hereof, the Trustee shall examine the document to determine whether it conforms to the
requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein). The Trustee, in its discretion, may make further
inquiry or investigation into such facts or matters as it sees fit.

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel conforming to Section 12.05 and the Trustee will not be liable for any
action it takes or omits to take in good faith in reliance on the certificate or opinion.

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

     (d) The Trustee will be under no obligation to exercise any of the rights or powers vested in
it by the Indenture at the request or direction of any of the Holders, unless such Holders have
offered to the Trustee security or indemnity reasonably satisfactory to it against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or direction.

76

 

     (e) The Trustee will not be liable for any action it takes or omits to take in good faith that
it believes to be authorized or within its rights or powers or for any action it takes or omits to
take in accordance with the direction of the Holders in accordance with Section 6.05 relating to
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under the Indenture.

     (f) The Trustee may consult with counsel, and the advice of such counsel or any Opinion of
Counsel will be full and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.

     (g) No provision of the Indenture will require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of its duties hereunder, or in the
exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss,
liability or expense.

     (h) In no event shall the Trustee be responsible or liable for special, indirect or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     (i) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any
event which is in fact such a default is received by the Trustee at the Corporate Trust Office of
the Trustee, and such notice references the Securities and this Indenture.

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

     Section 7.03 . Individual Rights of Trustee. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the
same with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and

the receivables or proceeds arising from the sale of the goods, wares or merchandise previously
constituting the security, provided the security is received by the Trustee simultaneously with the
creation of the creditor relationship arising from the making, drawing, negotiating or incurring of
the draft, bill of exchange, acceptance or obligation.

     Section 7.04 . Trustee’s Disclaimer. The Trustee (a) makes no representation as to the
validity or adequacy of the Indenture, the Security Documents or the Notes, (b) is not accountable

     Section 7.05 . Notice of Default. If any Default occurs and is continuing and is known to
the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it
occurs, unless the Default has been cured; provided that, except in the case of a default in the
payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so
long as a trust committee of directors of the Trustee in good faith determines that withholding the
notice is in the interest of the Holders. Notice to Holders under this Section will be given in
the manner and to the extent provided in Trust Indenture Act Section 313(c).

     Section 7.06 . Reports by Trustee to Holders. Within 60 days after each May 15, beginning

and file such reports with each stock exchange upon which its Notes are listed and with the
Commission as required by Trust Indenture Act Section 313(d).

     Section 7.07 . Compensation And Indemnity. (a) The Company will pay the Trustee
compensation as agreed upon in writing for its services. The compensation of the Trustee is not

incurred or made by the Trustee, including the reasonable compensation and expenses of the
Trustee’s agents and counsel.

     (b) Each of the Company and the Guarantors, jointly and severally, will indemnify the Trustee
for, and hold it harmless against, any loss, claim, damage

78

 

or liability or expense incurred by it
without negligence or bad faith on its part arising out of or in connection with the acceptance or
administration of the Indenture and its duties under the Indenture and the Notes, including the
costs and expenses of defending itself against any claim or liability and of complying with any
process served upon it or any of its officers in connection with the exercise or performance of any
of its powers or duties under the Indenture and the Notes.

     (c) To secure the Company’s payment obligations in this Section, the Trustee will have a lien
prior to the Notes on all money or property held or collected by the Trustee, in its capacity as
Trustee, except money or property held in trust to pay principal of, and interest on, particular
Notes. The benefits of this Section shall survive the termination of this Indenture.

notice to the Company.

     (ii) The Holders of a majority in principal amount of the outstanding Notes may remove
the Trustee by written notice to the Trustee and the Company.

     (iii) If the Trustee is no longer eligible under Section 7.10 or in the circumstances
described in Trust Indenture Act Section 310(b), any Holder that satisfies the
requirements of Trust Indenture Act Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     (iv) The Company may remove the Trustee if: (A) the Trustee is no longer eligible
under Section 7.10; (B) the Trustee is adjudged a bankrupt or an insolvent; (C) a receiver
or other public officer takes charge of the Trustee or its property; or (D) the Trustee
becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     (b) If the Trustee has been removed by the Holders, Holders of a majority in principal amount
of the Notes may appoint a successor Trustee with the consent of the Company. Otherwise, if the
Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the
Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its
written acceptance within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of a majority in principal amount

79

 

of the outstanding Notes may petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor Trustee.

     (c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the
retiring Trustee and to the Company, (i) the retiring Trustee will transfer, upon payment of its
fees and expenses hereunder, all property held by it as Trustee to the successor Trustee, subject
to the lien provided for in Section 7.07, (ii) the resignation or removal of the retiring Trustee
will become effective, and (iii) the successor Trustee will have all the rights, powers and duties
of the Trustee under the Indenture. Upon request of any successor Trustee, the Company will
execute any and all instruments for fully and vesting in and confirming to the successor Trustee
all such rights, powers and trusts. The Company will give notice of any resignation and any
removal of the Trustee and each appointment of a successor Trustee to all Holders, and include in
the notice the name of the successor Trustee and the address of its Corporate Trust Office.

     (d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

     (e) The Trustee agrees to give the notices provided for in, and otherwise comply with, Trust
Indenture Act Section 310(b).

     Section 7.09 . Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust business to, another
corporation or national banking association, the resulting, surviving or transferee corporation or
national banking association without any further act will be the successor Trustee with the same
effect as if the successor Trustee had been named as the Trustee in the Indenture.

     Section 7.10 . Eligibility. The Indenture must always have a Trustee that satisfies the
requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at
least $25,000,000 as set forth in its most recent published annual report of condition.

     Section 7.11 . Money Held in Trust. The Trustee will not be liable for interest on any money
received by it except as it may agree with the Company. Money held in trust by the Trustee need
not be segregated from other funds except to the extent required by law and except for money held
in trust under Article 8.

     Section 7.12 . Collateral Agent. (a) The Trustee is hereby appointed to act as the
Collateral Agent under the Security Documents, with such powers, rights and obligations as are
expressly delegated to the Collateral Agent by the

80

 

terms of this Indenture and by the Security
Documents. The Trustee may, from time to time, appoint another financial institution to act as
Collateral Agent so
long as such institution meets the requirements of Section 7.10. The Collateral Agent, acting
in its capacity as such, shall have only such duties with respect to the Collateral as are set
forth in the Security Documents.

     (b) Subject to the appointment and acceptance of a successor Collateral Agent as provided in
this subsection, the Collateral Agent (if other than the Trustee) may resign at any time by
notifying the Trustee and the Company. Upon any such resignation, the Trustee shall have the right
to appoint a successor Collateral Agent. If no successor shall have been so appointed by the
Trustee and shall have accepted such appointment within 30 days after the retiring Collateral Agent
gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Holders
and the Trustee, appoint a successor Collateral Agent which shall meet the eligibility requirements
of Section 7.10 and shall accept and comply in all material respects with the Security Documents,
including without limitation the maintenance of an office and the Cash Collateral Account in the
State of New York. Upon a successor’s acceptance of its appointment as Collateral Agent hereunder,
such successor shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Collateral Agent hereunder and under the Security Documents, and the
retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under
the Security Documents. If the Trustee shall be acting at any time as the Collateral Agent, then
it will be deemed to have resigned as Collateral Agent upon its replacement as Trustee pursuant to
Section 7.08, and the successor Trustee shall select (or may act as) the replacement Collateral
Agent.

     (c) At all times when the Trustee is not itself the Collateral Agent, the Company will deliver
to the Trustee copies of all Security Documents delivered to the Collateral Agent and copies of all
documents delivered to the Collateral Agent pursuant to the Security Documents.

will be discharged. Thereafter, the Trustee upon request will acknowledge in writing the discharge
of the Company’s obligations under the Notes and the Indenture except for the surviving obligations
specified above.

     Section 8.03 . Covenant Defeasance. After the 123rd day following the deposit referred to in

except to the extent required by law.

     Section 8.05 . Repayment to Company. Subject to Sections 7.07, 8.01, 8.02 and 8.03, the
Trustee will promptly pay to the Company upon request any excess money held by the Trustee at any
time and thereupon be relieved from all liability with respect to such money. The Trustee will pay
to the Company upon request any money held for payment with respect to the Notes that remains
unclaimed for two years, provided that before making such payment the Trustee

84

the Company publish once in a newspaper of general circulation in New York City, or send to each
Holder entitled to such money, notice that the money remains unclaimed and that after a date
specified in the notice (at least 30 days after the date of the publication or notice) any
remaining unclaimed balance of money will be repaid to the Company. After payment to the Company,
Holders entitled to such money must look solely to the Company for
payment, unless applicable law designates another Person, and all liability of the Trustee
with respect to such money will cease.

     Section 8.06 . Reinstatement. If and for so long as the Trustee is unable to apply any money

enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under
the Indenture and the Notes will be reinstated as though no such deposit in trust had been made.
If the Company makes any payment of principal of or interest on any Notes because of the
reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes
to receive such payment from the money or U.S. Government Obligations held in trust.

ARTICLE 9

Amendments, Supplements and Waivers

     Section 9.01 . Amendments Without Consent of Holders. The Company and the Trustee (and in

the Security Documents and/or the Notes without notice to or the consent of any Noteholder

     (a) to cure any ambiguity, defect or inconsistency or conform any provision to the
“Description of Notes” set forth in the Offering Circular;

163(f)(2)(B) of the Code;

85

     In addition, the Company may amend the Security Documents to secure additional Debt to be
Incurred by the Company or a Guarantor by Liens on the Collateral pursuant to the Security
Documents if such Debt is permitted to be Incurred and secured by such Liens under the Indenture.

     Section 9.02 . Amendments With Consent of Holders. (a) Except as otherwise provided in
Sections 6.02, 6.04 and 6.07 or paragraph (b), the Company and the Trustee (and, in the case of any
Security Document, the Collateral Agent) may amend or supplement the Indenture, the Security
Documents and/or the Notes with the written consent of the Holders of a majority in principal
amount of the outstanding Notes and the Holders of a majority in principal amount of the
outstanding Notes may waive future compliance by the Company with any provision of the Indenture,
the Security Documents or the Notes.

     (b) Notwithstanding
the provisions of paragraph (a), without the consent of each
Holder affected, an amendment or waiver may not

     (i) reduce the principal amount of or change the Stated Maturity of any installment
of principal of any Note,

     (ii) reduce the rate of or change the Stated Maturity of any interest payment on any
Note,

     (iii) reduce the amount payable upon the redemption of any Note or change the time of
any mandatory redemption or, in respect of an optional redemption, the times at which any
Note may be redeemed or, once notice of redemption has been given, the time at which it
must thereupon be redeemed,

     (iv) after the time an Offer to Purchase is required to have been made, reduce the
purchase amount or purchase price, or extend the latest expiration date or purchase date
thereunder,

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

86

interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or to
institute suit for the enforcement of any such payment,

     (viii) modify or change any provision of the Indenture affecting the ranking of the
Notes or any Note Guaranty in a manner adverse to the Holders of the Notes,

     (ix) make any change in any Note Guaranty that would adversely affect the
Noteholders, or effect a release of all or substantially all of the Collateral, or

     (x) make any change in the provisions of the Security Documents dealing with the
application of the proceeds of Collateral from the Lien under the Indenture and the
Security Documents with respect to the Notes that would adversely affect the Noteholders;

provided that the provisions of Section 4.12 and Section 4.13 may, except as provided above, be
amended or waived with the consent of Holders holding not less than 66 2/3% in aggregate principal
amount of the Notes.

     (c) It is not necessary for Noteholders to approve the particular form of any proposed
amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

     (d) An amendment, supplement or waiver under this Section will become effective on receipt by
the Trustee of written consents from the Holders of the requisite percentage in principal amount of
the outstanding Notes. After an amendment, supplement or waiver under this Section becomes
effective, the Company will send to the Holders affected thereby a notice briefly describing the
amendment, supplement or waiver. The Company will send supplemental indentures to Holders upon
request. Any failure of the Company to send such notice, or any defect therein, will not, however,
in any way impair or affect the validity of any such supplemental indenture or waiver.

     Section 9.03 . Effect of Consent. (a) After an amendment, supplement or waiver becomes
effective, it will bind every Holder unless it is of the type requiring the consent of each Holder
affected. If the amendment, supplement or waiver is of the type requiring the consent of each
Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it

87

 

and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting
Holder.

     (b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require
the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of
the changed terms on the Note and return it to the Holder, or exchange it for a new Note that
reflects the changed terms. The Trustee may also place an appropriate notation on any Note
thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not
affected by any failure to annotate or exchange Notes in this fashion.

     Section 9.04 . Trustee’s Rights and Obligations. The Trustee shall be provided with, and
will be fully protected in relying upon, an Opinion of Counsel stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by
the Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the
amendment, supplement or waiver so long as the same does not adversely affect the rights of the
Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver
that affects the Trustee’s own rights, duties or immunities under the Indenture.

     Section 9.05 . Conformity With Trust Indenture Act. Every supplemental indenture executed
pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

     Section 9.06 . Payments for Consents. Neither the Company nor any of its Subsidiaries or
Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by way
of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the Indenture, the Notes or any Security Document
unless such consideration is offered to be paid or agreed to be paid to all Holders of the Notes
that consent, waive or agree to amend such term or provision within the time period set forth in
the solicitation documents relating to the consent, waiver or amendment.

ARTICLE 10

Guaranties

     Section 10.01 . The Guaranties. Subject to the provisions of this Article, each Guarantor
hereby irrevocably and unconditionally guarantees, jointly and severally, on a secured basis, to
the Holders and to the Trustee the full and punctual payment (whether at Stated Maturity, upon
redemption, purchase pursuant to an Offer to Purchase or acceleration, or otherwise) of the
principal of,

88

 

premium, if any, and interest on, and all other amounts payable under, each Note, and
the full and punctual payment of all other amounts payable by the Company under the Indenture.
Upon failure by the Company to pay punctually any such amount, each Guarantor shall forthwith on
demand pay the amount not so paid at the place and in the manner specified in the Indenture.

     Section 10.02 . Guaranty Unconditional. The obligations of each Guarantor hereunder are
unconditional and absolute and, without limiting the generality of the foregoing, will not be
released, discharged or otherwise affected by:

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

     (2) any modification or amendment of or supplement to the Indenture, any Security Document or
any Note;

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

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

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

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

     Section 10.03 . Discharge; Reinstatement. Each Guarantor’s obligations hereunder will remain
in full force and effect until the principal of, premium, if any, and interest on the Notes and all
other amounts payable by the Company

89

 

under the Indenture have been paid in full. If at any time
any payment of the principal of, premium, if any, or interest on any Note or any other amount
payable by the Company under the Indenture is rescinded or must be otherwise restored or returned
upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guarantor’s
obligations hereunder with respect to such payment will be reinstated as though such payment had
been due but not made at such time.

     Section 10.04 . Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as well as any
requirement that at any time any action be taken by any Person against the Company or any other
Person.

     Section 10.05 . Subrogation and Contribution. Upon making any payment with respect to any
obligation of the Company under this Article, the Guarantor making such payment will be subrogated
to the rights of the payee against the Company with respect to such obligation, provided that the
Guarantor may not enforce either any right of subrogation, or any right to receive payment in the
nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so
long as any amount payable by the Company hereunder or under the Notes remains unpaid.

     Section 10.06 . Stay of Acceleration. If acceleration of the time for payment of any amount
payable by the Company under the Indenture or the Notes is stayed upon the insolvency, bankruptcy
or reorganization of the Company, all such amounts otherwise subject to acceleration under the
terms of the Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by
the Trustee or the Holders.

     Section 10.07 . Limitation on Amount of Guaranty. Notwithstanding anything to the contrary
in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that
it is the intention of all such parties that the Note Guaranty of such Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the
Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each
Guarantor under its Note Guaranty are limited to the maximum amount that would not render the
Guarantor’s obligations subject to avoidance under applicable fraudulent transfer provisions of the
United States Bankruptcy Code or any comparable provision of state law.

     Section 10.08 . Execution and Delivery of Guaranty. The execution by each Guarantor of the
Indenture (or a supplemental indenture substantially in the form of Exhibit B) evidences the Note
Guaranty of such Guarantor, whether or

90

 

not the person signing as an officer of the Guarantor still
holds that office at the time of authentication of any Note. The delivery of any Note by the
Trustee after authentication constitutes due delivery of the Note Guaranty set forth in the
Indenture on behalf of each Guarantor.

     Section 10.09 . Release of Guaranty. The Note Guaranty of a Guarantor will terminate upon

     (a) a sale or other disposition (including by way of consolidation or merger) of the Guarantor
or the sale or disposition of all or substantially all the assets of the Guarantor (in each case
other than to the Company or a Restricted Subsidiary) otherwise permitted by the Indenture,

     (b) the designation in accordance with the Indenture of the Guarantor as an Unrestricted
Subsidiary, or

     (c) defeasance or discharge of the Notes, as provided in Article 8.

     Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of
Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in
order to evidence the release of the Guarantor from its obligations under its Note Guaranty.

ARTICLE 11

Security Arrangements

     Section 11.01 . Security. (a) In order to secure the Obligations of the Company under this
Indenture and the Notes, the Company will execute and deliver to the Trustee on or prior to the
Issue Date each Security Document to which it is or is to be a party that is intended to be
effective upon the Issue Date and create the Liens intended to be created thereunder, with the
priority set forth therein and in the Intercreditor Agreement, on the Collateral. In order to
secure the Obligations of each Guarantor under its Note Guaranty, this Indenture and the Notes,
each Guarantor will execute and deliver to the Trustee prior to the Issue Date each Security
Document to which it is or is to be a party that is intended to be effective upon the Issue Date
and create the Liens intended to be created thereunder, with the priority set forth therein and in
the Intercreditor Agreement, on the Collateral.

     (b) Within 30 days after (i) any Restricted Subsidiary becomes a Guarantor in accordance with
Section 4.11 or (ii) the Company or any Guarantor acquires any material property that is not
automatically subject to a perfected security interest under the Security Documents, the Company or
Guarantor shall

91

 

notify the Collateral Agent thereof and, in each case at the sole cost and expense
of the Company or Guarantor, execute and deliver to the Collateral Agent such mortgages, security
agreement supplements and other documentation (in form and scope, and covering such Collateral on
such terms, in each case consistent with the mortgages, security agreements and other security
documents in effect on the Issue Date), and take such additional actions (including any of the
actions described in Section 4.19(b)), as the Collateral Agent may deem reasonably appropriate or
advisable to create and fully perfect in favor of the secured parties under the Security Documents
a valid and enforceable security interest in (and in the case of real property, mortgage lien on)
such Collateral, which shall be free of any other Liens except for Permitted Liens (including, in
the case of the Secondary Collateral, the first-priority Lien of the holders of Bank Obligations).
Any security interest provided pursuant to this Section 11.01(b) shall be accompanied with such
Opinions of Counsel to the Company as customarily given by Company’s counsel in the relevant
jurisdiction, in form and substance customary for such jurisdiction and substantially consistent
with that provided to the lenders under the Credit Agreement. In addition, the Company shall
deliver an Officers’ Certificate to the Collateral Agent certifying that the necessary measures have
been taken to perfect the security interest in such property.

     (c) The Company and the Guarantors shall comply with all covenants and agreements contained in
the Security Documents.

     (d) Each Holder, by accepting a Note, agrees to all of the terms and provisions of the
Security Documents, as the same may be amended from time to time pursuant to the provisions of the
Indenture and the Security Documents.

     (e) As among the Holders, the Collateral as now or hereafter constituted shall be held for the
equal and ratable benefit of the Holders without preference, priority or distinction of any thereof
over any other by reason of differences in time of issuance, sale or otherwise, as security for the
Obligations under this Indenture and the Notes.

     (f) To the extent applicable, the Company will comply with Section 313(b) of the Trust
Indenture Act, relating to reports, and Section 314(d) of the Trust Indenture Act, relating to the
release of property and to the substitution therefor of any property to be pledged as Collateral
for the Notes. Any certificate or opinion required by Section 314(d) of the Trust Indenture Act
may be made by an Officer of the Company except in cases where Section 314(d) requires that such
certificate or opinion be made by an independent engineer, appraiser or other expert, who shall be
reasonably satisfactory to the Trustee. Notwithstanding anything to the contrary herein, the
Company and its Subsidiaries will not be required to comply with all or any portion of Section
314(d) of the Trust Indenture Act if they determine, in good faith based on advice of outside
counsel,

92

 

that under the terms of that section and/or any interpretation or guidance as to the
meaning thereof of the Commission and its staff, including “no action” letters or exemptive orders,
all or any portion of Section 314(d) of the Trust Indenture Act is inapplicable to the released
Collateral.

     Section 11.02 . Cash Collateral Account. (a) The Company and the Guarantors shall deposit in
the Cash Collateral Account the Net Cash Proceeds from any sale, lease, transfer or other
disposition (or series of related sales, leases, transfers or other dispositions) of Primary
Collateral having an aggregate fair market value of more than $2.5 million.

     (b) All Casualty Proceeds received by the Collateral Agent, the Company or any Guarantor in
respect of Primary Collateral shall be applied as follows:

     (i) if the amount of such Casualty Proceeds is less than $2,500,000, such Casualty
Proceeds shall be retained by the Company or the relevant Guarantor, as the case may be,
and used to restore, repair, replace (including with an asset of like kind) or rebuild the
asset in respect
of which such Casualty Proceeds were received (to the extent required by the
applicable Security Document) or otherwise such Proceeds may be used in accordance with
Section 4.13(c) or Section 4.13(d); and

     (ii) if the amount of such Casualty Proceeds is equal to or greater than $2,500,000,
such Casualty Proceeds shall be deposited and held in the Cash Collateral Account and be
released from that account as provided in Section 11.02(c) below.

     (c) Amounts held in the Cash Collateral Account may only be released to the Company or the
applicable Guarantor for use as permitted by Section 4.13(c) or Section 4.13(d) and, in the case of
Section 4.13(d), will be released to the Company or the applicable Guarantor if remaining after the
consummation of the Offer to Purchase.

     (d) Notwithstanding the foregoing, the Company will not be required to deposit any Casualty
Proceeds to the extent that it furnishes the Collateral Agent and the Trustee with an Officers’
Certificate certifying that it has invested an amount in compliance with Section 4.13(c) or Section
4.13(d) equal to, or in excess of, the amount of such proceeds in anticipation of receipt of such
funds.

     (e) The Company and Guarantors will be required to comply with the requirements of Section
11.05 before any Collateral held in the Cash Collateral Account may be released from the Lien of
the Security Documents.

93

 

     Section 11.03 . Authorization of Actions to be Taken.

     (a) The Trustee is authorized and empowered to enter into the Security Documents, whether as
Trustee or Collateral Agent, and to receive for the benefit of the Holders of Notes any funds
collected or distributed under the Security Documents to which the Trustee is a party and to make
further distributions of such funds to the Holders of Notes according to the provisions of this
Indenture.

     (b) Subject to the provisions of Article 7 and the Intercreditor Agreement, the Trustee, in
its sole discretion and without the consent of the Holders of Notes, may, or at the direction of
the Holders of a majority in principal amount of the Notes then outstanding, the Trustee shall,
direct on behalf of the Holders of Notes, the Collateral Agent to take all actions it deems
necessary or appropriate in order to:

     (1) foreclose upon and take possession of all Collateral pursuant to, or take any
other action to enforce, the provisions of the Security Documents;

     (2) enforce any of the terms of the Intercreditor Agreement and the Security
Documents to which the Trustee or the Collateral Agent is a party; or

     (3) collect and receive payment of all obligations in respect of the Notes, the Note
Guaranties and this Indenture.

Subject to the Intercreditor Agreement and Article 7, the Trustee is authorized and empowered to
institute and maintain such suits and proceedings as it may deem expedient to protect or enforce
the Liens on the Collateral or the other rights under the Security Documents to which the Trustee
or the Collateral Agent is a party or to prevent any impairment of Collateral by any acts that may
be unlawful or in violation of such Security Documents or this Indenture, and such suits and
proceedings as the Trustee or the Collateral Agent may deem expedient to preserve or protect its
interests and the interests of the Holders in the Collateral, including power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or
other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if
the enforcement of, or compliance with, such enactment, rule or order would impair the Liens or
other rights under such Security Documents or hereunder or be prejudicial to the interests of
Holders or the Trustee.

     Section 11.04 . Determinations Relating to Collateral. In the event (i) the Trustee shall
receive any written request from the Company, a Guarantor or the Collateral Agent under any
Security Document for consent or approval with

94

 

respect to any matter or thing relating to any
Collateral or the Company’s or such Guarantor’s obligations with respect thereto, (ii) there shall
be due to or from the Trustee or the Collateral Agent under the provisions of any Security Document
any material performance or the delivery of any material instrument or (iii) the Trustee shall
become aware of any nonperformance by the Company or a Guarantor of any covenant or any breach of
any representation or warranty of the Company or such Guarantor set forth in any Security Document,
then, in each such event, the Trustee shall be entitled to hire experts, consultants, agents and
attorneys to advise the Trustee on the manner in which the Trustee should respond, or direct the
Collateral Agent to respond, to such request or render any requested performance or respond, or
direct the Collateral Agent to respond, to such nonperformance or breach; provided that the
Trustee’s right to direct the Collateral Agent to respond shall be subject to the terms of the
Security Documents. The Trustee shall be fully protected in the taking of any action recommended
or approved by any such expert, consultant, agent or attorney or agreed to by the Holders of a
majority in principal amount of the outstanding Notes.

     Section 11.05. Release of Liens. (a) The Liens on the Collateral securing the Notes will
be released:

     (i) upon payment in full of principal, interest and all other Obligations on the
Notes issued under the Indenture or discharge or defeasance thereof (in accordance with
Article 8);

     (ii) upon release of a Note Guaranty (with respect to the Liens securing such Note
Guaranty granted by such Guarantor); and

     (iii) in connection with any disposition of Collateral to any Person other than the
Company or any of its Restricted Subsidiaries (but excluding any transaction subject to
Section 5.01) that is permitted by the Indenture (with respect to the Lien on such
Collateral).

     (b) Upon delivery to the Trustee of an Officers’ Certificate requesting execution of an
instrument confirming the release of the Liens pursuant to
Section 11.05(a), accompanied by:

     (1)
an Opinion of Counsel confirming that such release is permitted by
Section 11.05(a);

     (2) all instruments requested by the Company to effectuate or confirm such release;
and

95

 

     (3) such other certificates and documents as the Trustee may reasonably request to
confirm the matters set forth in Section 11.05(a),

the Trustee will, if such instruments and confirmation are reasonably satisfactory to the Trustee,
promptly execute and deliver, such instruments.

     (c) All instruments effectuating or confirming any release of any Liens will have the effect
solely of releasing such Liens as to the Collateral described therein, on customary terms and
without any recourse, representation, warranty or liability whatsoever.

     (d) The Company will bear and pay all costs and expenses associated with any release of Liens
pursuant to this Section 11.05, including all reasonable fees and disbursements of any attorneys or
representatives acting for the Trustee or for the Collateral Agent.

     (e) Any release of Collateral in accordance with the provisions of this Indenture, the
Security Documents and the Trust Indenture Act will not be deemed to impair the security under this
Indenture, and any engineer or appraiser may rely on this Section 11.05(e) in delivering a
certificate requesting release so long as all other provisions of this Indenture and the Trust
Indenture Act with respect to such release have been complied with.

     Section 11.06 . Agreement for the Benefit of Holders of First Priority Liens. The Trustee
and each Holder of Notes by accepting a Note agrees, that:

     (a) The Second Priority Liens are, to the extent and in the manner provided in the
Intercreditor Agreement, subject to and subordinate in ranking to all present and future First
Priority Liens; and the Intercreditor Agreement will be enforceable by the holders of First
Priority Liens, for the benefit of the holders of Obligations secured thereby, until the
satisfaction pursuant to the terms thereof of all such Obligations outstanding at the time of such
release.

     (b) Without the necessity of any consent of the Trustee or any Holder of the Notes, the
holders of the Bank Obligations may change, waive, modify or vary any Security Document relating to
Secondary Collateral with respect to which such holders have a First Priority Lien, subject to the
limitations set forth in the Intercreditor Agreement; provided, that the Trustee shall be given
notice of any such change, waiver, modification or variance.

     (c) As among the agent under the Credit Agreement, the Trustee and the Holders of the Notes
and the holders of the Bank Obligations, the holders of the Bank Obligations and the agent under
the Credit Agreement will have the sole ability to control and obtain remedies with respect to all
Secondary Collateral

96

 

without the necessity of any consent or of any notice to the Trustee, or any
such Holder, subject to the limitations set forth in the Intercreditor Agreement.

     (d) Any or all Liens as set forth in, and granted under the Security Documents relating to the
Secondary Collateral for the benefit of the Holders will be automatically (to the extent permitted
by law) and simultaneously released, without the necessity of any consent of the Trustee or any
Holders, upon a release of the First Priority Liens on such Collateral, subject to the exceptions
set forth in the Intercreditor Agreement.

     Section 11.07 . Notes And Note Guaranties Not Subordinated. The provisions of Sections 11.06
and 11.07 are intended solely to set forth the relative ranking, as Liens, of the Second Priority
Liens as against the First Priority Liens. The Notes and the Note Guaranties are senior
unsubordinated obligations of the Company and the Guarantors. Neither the Notes and the Note
Guaranties nor the exercise or enforcement of any right or remedy for the payment or collection
thereof (other than the exercise of rights and remedies in respect of the Collateral, which are
subject to the Intercreditor Agreement) are intended to be, or will ever be by reason of the
provisions of Sections 11.06 and 11.07, in any respect subordinated, deferred, postponed,
restricted or prejudiced.

ARTICLE 12

     Section 12.02 . Noteholder Communications; Noteholder Actions. (a) The rights of Holders to
communicate with other Holders with respect to the Indenture or the Notes are as provided by the
Trust Indenture Act, and the Company and the Trustee shall comply with the requirements of Trust
Indenture Act Sections 312(a) and 312(b). Neither the Company nor the Trustee will be held
accountable by reason of any disclosure of information as to names and addresses of Holders made
pursuant to the Trust Indenture Act.

     (b) (i) Any request, demand, authorization, direction, notice, consent to amendment,
supplement or waiver or other action provided by this Indenture to be given or taken by a Holder
(an “act”) may be evidenced by an instrument signed by the Holder delivered to the Trustee. The
fact and date of the execution of the instrument, or the authority of the person executing it, may
be proved in any manner that the Trustee deems sufficient.

97

 

     (ii) The Trustee may make reasonable rules for action by or at a meeting of Holders,
which will be binding on all the Holders.

     (c) Any act by the Holder of any Note binds that Holder and every subsequent Holder of a Note
that evidences the same debt as the Note of the acting Holder, even if no notation thereof appears
on the Note. Subject to paragraph (d), a Holder may revoke an act as to its Notes, but only if the
Trustee receives the notice of revocation before the date the amendment or waiver or other
consequence of the act becomes effective.

     (d) The Company may, but is not obligated to, fix a record date (which need not be within the
time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the purpose of
determining the Holders entitled to act with respect to any amendment or waiver or in any other
regard, except that during the continuance of an Event of Default, only the Trustee may set a
record date as to notices of default, any declaration or acceleration or any other remedies or
other consequences of the Event of Default. If a record date is fixed, those Persons that were

sufficiency with respect to other Holders.

entitled to receive such notice, either before or after the event, and the waiver will be the
equivalent of the notice. Waivers of notice by Holders must be filed with the Trustee, but such
filing is not a condition precedent to the validity of any action taken in reliance upon such
waivers.

application by the Company to the Trustee to take any action under the Indenture, the Company will

examination or investigation as is necessary to enable the person to express an informed opinion as

     (d) a statement as to whether or not, in the opinion of each such person, such condition or
covenant has been complied with, provided that an Opinion of Counsel may rely on an Officers’
Certificate or certificates of public officials with respect to matters of fact.

payment of any principal of, premium, if any, or interest on any Note (including any payment to be
made on any date fixed for redemption or purchase of any Note) is due on a day which is not a
Business Day, then the payment need not be made on such date, but may be made on the next Business
Day with the same force and effect as if made on such date, and no interest will accrue for the
intervening period.

and the Notes will bind its successors. All agreements of the Trustee in the Indenture will bind
its successor.

     Section 12.10 . Duplicate Originals. The parties may sign any number of copies of the
Indenture. Each signed copy shall be an original, but all of them together represent the same
agreement.

     Section 12.11 . Separability. In case any provision in the Indenture or in the Notes is
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions will not in any way be affected or impaired thereby.

     Section 12.12 . Table of Contents and Headings. The Table of Contents, Cross-Reference Table
and headings of the Articles and Sections of the Indenture have been inserted for convenience of
reference only, are not to be considered a

100

 

part of the Indenture and in no way modify or restrict
any of the terms and provisions of the Indenture.

Stockholders. No director, officer, employee, incorporator, member or stockholder of the Company
or any Guarantor, as such, will have any liability for any obligations of the Company or such
Guarantor under the Notes, any Note Guaranty, the Indenture or any Security Document or for any
claim based on, in respect of, or by reason of, such obligations. Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO

directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

2. Indentures; Note Guaranty.

     This is one of the Notes issued under an Indenture dated as of December 29, 2006 (as amended
from time to time, the “Indenture”), among the Company, the Guarantors party thereto and The Bank
of New York Trust Company, N.A., as Trustee. Capitalized terms used herein are used as defined in
the Indenture unless otherwise indicated. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes
are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture
Act for a statement of all such terms. To the extent permitted by applicable law, in the event of
any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the
Indenture will control.

     The Notes are general obligations of the Company, secured by Liens on the Collateral pursuant
to the Security Documents. The Indenture limits the original aggregate principal amount of the
Notes to $225,000,000, but Additional Notes may be issued pursuant to the Indenture, and the
originally issued Notes and all such Additional Notes vote together for all purposes as a single
class. This Note is guaranteed as set forth in the Indenture.

3. Redemption and Repurchase; Discharge Prior to Redemption or Maturity.

     This Note is subject to optional redemption, and may be the subject of an Offer to Purchase,
as further described in the Indenture. There is no sinking fund or mandatory redemption applicable
to this Note.

     If the Company deposits with the Trustee money or U.S. Government Obligations sufficient to
pay the then outstanding principal of, premium, if any, and accrued interest on the Notes to
redemption or maturity, the Company may in certain circumstances be discharged from the Indenture,
the Notes and the Security Documents or may be discharged from certain of its obligations under
certain provisions of the Indenture.

4. Registered Form; Denominations; Transfer; Exchange.

     The Notes are in registered form without coupons in denominations of $1,000 in principal
amount and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange
of Notes in accordance with the Indenture. The Trustee may require a Holder to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted
by the Indenture. Pursuant to the Indenture, there are certain periods during which the
Trustee will not be required to issue, register the transfer of or exchange any Note or certain
portions of a Note.

5. Defaults and Remedies.

     If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due
and payable. If a bankruptcy or insolvency default with respect to the Company occurs and is
continuing, the Notes automatically become due and payable. Holders may not enforce the Indenture
or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory
to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a
majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise
of remedies.

6. Amendment and Waiver.

     Subject to certain exceptions, the Indenture, the Notes and the Security Documents may be
amended, or default may be waived, with the consent of the Holders of a majority in principal
amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company and
the Trustee (and in the case of the Security Documents, the Collateral Agent) may amend or
supplement the Indenture, the Notes or the Security Documents to, among other things, cure any
ambiguity, defect or inconsistency if such amendment or supplement does not adversely affect the
interests of the Holders in any material respect.

for the rights under Section 11.08(a)) of the Indenture shall be granted to and may be exercised by
the Holders of a majority in principal amount of the Outstanding Notes. Notwithstanding anything

payment date, as set forth on the face of this Note, at the rate of
12 1⁄2 % per
annum (subject to adjustment as provided below).

     Interest will be payable semiannually (to the holders of record of the Notes at the close of
business on the June 15 or December 15 immediately preceding the interest payment date) on each
interest payment date, commencing July 1, 2007.

     Notwithstanding the foregoing, on or before any interest payment date, the Company may defer
the payment of a portion of the interest due on such interest payment date at a rate of up to 7.5%
per annum (the “Deferred Interest Payment”). If the Company elects to defer the payment of the
Deferred Interest Payment as aforesaid, interest at a rate of 12.5% per annum will accrue on the
principal amount of the Note and on the accrued but unpaid Deferred Interest Payments. The Company

authenticated between a regular record date and the next interest payment date, from such interest
payment date) or, if no interest has been paid, from the Issue Date. Interest will be computed on
the basis of a 360-day year of twelve 30-day months.

Company for the payment of such interest, whether or not such day is a Business Day. At least 15
days before a special record date, the Company will send to each Holder and to the Trustee a notice
that sets forth the special record date, the payment date and the amount of interest to be paid.

     (a) In the event an indenture in required to be qualified under the TIA, with respect to the
Notes, or at any time upon the request of Holders of in excess of 25% in aggregate principal amount
of the outstanding Notes, the Company shall appoint a trustee (the “Trustee”) who satisfies the
eligibility requirements set forth in Section 7.10 of the Indenture and, in any such event, the
Company shall take whatever actions are necessary to cause an Indenture substantially in the form
of Exhibit A attached hereto to be executed and delivered by the Company and the Trustee and to be
qualified under the TIA. In such event, (i) this Note shall be deemed to be one of an issue of
Notes of the Company issued under the Indenture; (ii) the terms of the Notes shall be deemed to
include those stated in the Indenture and those made part of the Indenture by reference to the TIA,
as amended from time to time; and (iii) the Notes shall be subject to all such terms. Holders of
Notes are referred to the Indenture and the TIA for a statement of all such terms. In such event,
the Company may require holders of the Notes, and each Holder by his or her acceptance hereof
agrees upon the Company’s request, to surrender to the Trustee all Notes in the form hereof in
exchange for replacement Notes substantially in the form of Exhibit A to the Indenture.

     (b) The Notes are general unsecured obligations of the Company. The Indenture limits the
original aggregate principal amount of the Notes to $75,000,000, but Additional Notes may be issued
pursuant to the Indenture, and the originally issued Notes and all such Additional Notes vote
together for all

7

 

purposes as a single class. This Note is subordinated as set forth in the Indenture to all
Obligations in respect of Senior Debt (including all interest accrued or accruing on Senior Debt
after the commencement of any bankruptcy, insolvency or reorganization or similar case or
proceeding at the contract rate (including, without limitation, any contract rate applicable upon

guarantied, on a senior subordinated basis, as set forth in the Indenture.

4. Redemption and Repurchase; Discharge Prior to Redemption or Maturity.

     This Note is subject to optional redemption, and may be the subject of an Offer to Purchase,

to this Note.

     If the Company deposits with the Trustee money or U.S. Government Obligations sufficient to
pay the then outstanding principal of, premium, if any, and accrued interest on the Notes to
redemption or maturity, the Company may in certain circumstances be discharged from the Indenture,
the Notes and the Security Documents or may be discharged from certain of its obligations under
certain provisions of the Indenture.

5. Registered Form; Denominations; Transfer; Exchange.

     The Notes are in registered form without coupons in denominations of $1,000 in principal
amount and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange
of Notes in accordance with the Indenture. The Trustee may require a Holder to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. Pursuant to the Indenture, there are certain periods during which the Company will
not be required to issue, register the transfer of or exchange any Note or certain portions of a
Note.

6. Defaults and Remedies.

     If an Event of Default, as defined in the Indenture, occurs and is continuing, Holders of at
least 25% in principal amount of the Notes may declare all the Notes to be due and payable. If a
bankruptcy or insolvency default with respect to the Company occurs and is continuing, the Notes
automatically become due and payable. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the Notes then outstanding may direct the Trustee in its exercise of remedies.

     7. Amendment and Waiver.

inconsistency if such amendment or supplement does not adversely affect the interests of the
Holders in any material respect.

3(b) hereof and Article 11 set out in the Indenture, with the right and ability to enforce such

provisions of (i) Section 1 incorporating the terms and conditions of the Indenture (with respect
to Article 11 thereof), (ii) Section 3(b) or (iii) Exhibit A hereof (with respect to amendments
that affect the rights of any holder of Senior Debt under Article 11 of Exhibit A), in each case

and evidence as the Company may reasonably require) that a Note is eligible for resale pursuant to

     (x) sold pursuant to an effective registration statement under the

the Company may instruct the Trustee to cancel the Note and issue to the Holder thereof (or to its

instruction.

     (e) By its acceptance of any Note bearing the Restricted Legend (or any beneficial interest in

     Section 2.02 . Execution and Authentication; Exchange Notes; Additional Notes. (a) An

signature is on a Note no longer holds that office at the time the Note is authenticated, the

authentication on the Note, with the signature conclusive evidence that the Note has been
authenticated under the Indenture.

     (c) At any time and from time to time after the execution and delivery of the Indenture, the

     (2) whether the Notes are to be Initial Notes, Additional Notes

     (3) in the case of Initial Additional Notes, that the issuance of

     (4) whether the Notes are to be issued as one or more Global

the Trustee may appoint an Authenticating Agent, in which case each reference in the Indenture to
the Trustee in respect of the obligations of the Trustee to be performed by that Agent will be
deemed to be references to the Agent. The Company may act as Registrar or (except for purposes of
Article 8) Paying Agent. In each case the Company and the Trustee will enter into an appropriate
agreement with the Agent implementing the provisions of the Indenture relating to the obligations
of the Trustee to be performed by the Agent and the related rights. The Company initially appoints
the Trustee as Registrar and Paying Agent.

     (b) 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 the Holders or the Trustee all money held by
the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify
the Trustee of any default by the Company in making any such payment. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and account for any funds
disbursed, and the Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require the Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no
further liability for the money so paid over to the Trustee.

     Section 2.04 . Replacement Notes. If a mutilated Note is surrendered to the Trustee or if a
Holder claims that its Note has been lost, destroyed or wrongfully taken, the Company will issue
and the Trustee will authenticate a replacement Note of like tenor and principal amount and bearing
a number not contemporaneously outstanding. Every replacement Note is an additional obligation of
the Company and entitled to the benefits of the Indenture. If required by the Trustee or the
Company, an indemnity must be furnished that is sufficient in the judgment of both the Trustee and
the Company to protect the Company and the Trustee from any loss they may suffer if a Note is
replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in
replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken Note has become or is
about to become due and payable, the Company in its discretion may pay the Note instead of issuing
a replacement Note.

30

 

     Section 2.05 . Outstanding Notes. (a) Notes outstanding at any time are all Notes that have
been authenticated by the Trustee except for

     (i) Notes cancelled by the Trustee or delivered to it for cancellation;

     (ii) any Note which has been replaced pursuant to Section 2.04 unless and until the
Trustee and the Company receive proof satisfactory to them that the replaced Note is held
by a bona fide purchaser; and

     (iii) on or after the maturity date or any redemption date or date for purchase of
the Notes pursuant to an Offer to Purchase, those Notes payable or to be redeemed or
purchased on that date for which the Trustee (or Paying Agent, other than the Company or
an Affiliate of the Company) holds money sufficient to pay all amounts then due.

     (b) A Note does not cease to be outstanding because the Company or one of its Affiliates holds
the Note, provided that in determining whether the Holders of the requisite principal amount of the
outstanding Notes have given or taken any request, demand, authorization, direction, notice,
consent, waiver or other action hereunder, Notes owned by the Company or any Affiliate of the
Company will be disregarded and deemed not to be outstanding, (it being understood that in
determining whether the Trustee is protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other action, only Notes which the Trustee
knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any
Affiliate of the Company.

     Section 2.06 . Temporary Notes. Until definitive Notes are ready for delivery, the Company
may prepare and the Trustee will authenticate temporary Notes. Temporary Notes will be
substantially in the form of definitive Notes but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the Officer executing the temporary Notes, as
evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company
will cause definitive Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of
the temporary Notes at the office or agency of the Company designated for the purpose pursuant to
Section 4.02, without charge to the Holder. Upon surrender for cancellation of any temporary Notes
the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like
principal amount of definitive Notes of authorized denominations.

31

 

Until so exchanged, the
temporary Notes will be entitled to the same benefits under the Indenture as definitive Notes.

     Section 2.07 . Cancellation. The Company at any time may deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes
previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the
Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or
payment. The Trustee will cancel all Notes surrendered for transfer, exchange, payment or
cancellation and dispose of them in accordance with its normal procedures or the written
instructions of the Company. The Company may not issue new Notes to replace Notes it has paid in
full or delivered to the Trustee for cancellation.

     Section 2.08 . CUSIP and CINS Numbers. The Company in issuing the Notes may use “CUSIP” and
“CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or
exchange or in Offers to Purchase as a convenience to Holders, the notice to 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 or Offer to Purchase. The Company will promptly
notify the Trustee of any change in the CUSIP or CINS numbers.

     Section 2.09 . Registration, Transfer and Exchange. (a) The Notes will be issued in
registered form only, without coupons, and the Company shall cause the Trustee to maintain a
register (the “Register”) of the Notes, for registering the record ownership of the Notes by the
Holders and transfers and exchanges of the Notes.

     (b) (i) Each Global Note will be registered in the name of the Depositary or its nominee and,
so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

     (ii) Each Global Note will be delivered to the Trustee as custodian for the
Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be
limited to transfers thereof in whole, but not in part, to the Depositary, its successors
or their respective nominees, except (1) as set forth in Section 2.09(b)(iv) and (2)
transfers of portions thereof in the form of Certificated Notes may be made upon request
of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given
to the Trustee by or on behalf of the Depositary in accordance with customary procedures
of the Depositary and in compliance with this Section and Section 2.10.

32

 

     (iii) Agent Members will have no rights under the Indenture with respect to any Global
Note held on their behalf by the Depositary, and the Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of
such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the
Depositary or its nominee may grant proxies and otherwise authorize any Person (including
any Agent Member and any Person that holds a beneficial interest in a Global Note through
an Agent Member) to take any action which a Holder is entitled to take under the Indenture
or the Notes, and nothing herein will 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 security.

     (iv) If (x) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for a Global Note and a successor depositary is not appointed by
the Company within 90 days of the notice or (y) an Event of Default has occurred and is
continuing and the Trustee has received a request from the Depositary, the Trustee will
promptly exchange each beneficial interest in the Global Note for one or more Certificated
Notes in authorized denominations having an equal aggregate principal amount registered in
the name of the owner of such beneficial interest, as identified to the Trustee by the
Depositary, and thereupon the Global Note will be deemed canceled. If such Note was an
Offshore Global Note, then the Certificated Notes issued in exchange therefor will not
bear the Restricted Legend.

     (c) Each Certificated Note will be registered in the name of the holder thereof or its
nominee.

     (d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or
exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized
denomination by presenting to the Trustee a written request therefor stating the name of the
proposed transferee or requesting such an exchange, accompanied by any certification, opinion or
other document required by Section 2.10. The Trustee will promptly register any transfer or
exchange that meets the requirements of this Section by noting the same in the register maintained
by the Trustee for the purpose; provided that

     (x) no transfer or exchange will be effective until it is registered in such register
and

     (y) the Trustee will not be required (i) to issue, register the transfer of or
exchange any Note for a period of 15 days before a selection of Notes to be redeemed or
purchased pursuant to an Offer to Purchase,

33

 

(ii) to register the transfer of or exchange
any Note so selected for redemption or purchase in whole or in part, except, in the case
of a partial redemption or purchase, that portion of any Note not being redeemed or
purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to
occur after a Regular Record Date but on or before the corresponding Interest Payment
Date, to register the transfer of or
exchange any Note on or after the Regular Record Date and before the date of
redemption or purchase. Prior to the registration of any transfer, the Company, the
Trustee and their agents will treat the Person in whose name the Note is registered as the
owner and Holder thereof for all purposes (whether or not the Note is overdue), and will
not be affected by notice to the contrary.

     From time to time the Company will execute and the Trustee will authenticate additional Notes
as necessary in order to permit the registration of a transfer or exchange in accordance with this
Section.

     No service charge will be imposed in connection with any transfer or exchange of any Note, but
the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than a transfer tax or other similar
governmental charge payable upon exchange pursuant to subsection (b)(iv)).

     (e) (i) Global Note to Global Note. If a beneficial interest in a Global Note is transferred
or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a
decrease in the principal amount of the Global Note being transferred or exchanged equal to the
principal amount of such transfer or exchange and (y) record a like increase in the principal
amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to
a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an
interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such
Global Note and become an interest in the other Global Note and, accordingly, will thereafter be
subject to all transfer and exchange restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an interest.

     (ii) Global Note to Certificated Note. If a beneficial interest in a Global Note is
transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease
in the principal amount of such Global Note equal to the principal amount of such transfer
or exchange and (y) deliver one or more new Certificated Notes in authorized denominations
having an equal aggregate principal amount to the transferee (in the case of a transfer)
or the owner of such beneficial interest (in the case of an

34

 

exchange), registered in the
name of such transferee or owner, as applicable.

     (iii) Certificated Note to Global Note. If a Certificated Note is transferred or
exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such
Certificated Note, (y) record an increase in the principal amount of such Global Note
equal to the principal amount of such transfer or exchange and (z) in the event that such
transfer or exchange involves less than the entire principal amount of the canceled
Certificated Note, deliver to the Holder thereof one or more new Certificated Notes
in authorized denominations having an aggregate principal amount equal to the
untransferred or unexchanged portion of the canceled Certificated Note, registered in the
name of the Holder thereof.

     (iv) Certificated Note to Certificated Note. If a Certificated Note is transferred
or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated
Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in
authorized denominations having an aggregate principal amount equal to the principal
amount of such transfer or exchange to the transferee (in the case of a transfer) or the
Holder of the canceled Certificated Note (in the case of an exchange), registered in the
name of such transferee or Holder, as applicable, and (z) if such transfer or exchange
involves less than the entire principal amount of the canceled Certificated Note, deliver
to the Holder thereof one or more Certificated Notes in authorized denominations having an
aggregate principal amount equal to the untransferred or unexchanged portion of the
canceled Certificated Note, registered in the name of the Holder thereof.

     Section 2.10 . Restrictions on Transfer and Exchange. (a) The transfer or exchange of any
Note (or a beneficial interest therein) may only be made in accordance with this Section and
Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable
rules and procedures of the Depositary. The Trustee shall refuse to register any requested
transfer or exchange that does not comply with the preceding sentence.

     (b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest
therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of
the type set forth opposite in column B below may only be made in compliance with the certification

     Section 3.01 . Optional Redemption. At any time and from time to time, the Company may
redeem the Notes, in whole or in part, at a redemption price equal to 100% of principal amount plus
accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption
date.

     Section 3.02 . [Reserved]

     Section 3.03 . Method and Effect of Redemption. (a) If the Company elects to redeem Notes,
it must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed
by delivering an Officers’ Certificate at

37

 

least 45 days before the redemption date (unless a
shorter period is satisfactory to the Trustee). If fewer than all of the Notes are being redeemed,
the Officers’ Certificate must also specify a record date not less than 15 days after the date of
the notice of redemption is given to the Trustee, and the Trustee will select the Notes to be
redeemed pro rata, by lot or by any other method the Trustee in its sole discretion deems fair and
appropriate, in denominations of $1,000 in principal amount and any multiple of $1,000 in excess
thereof. The Trustee will notify the Company promptly of the Notes or portions of Notes to be
called for redemption. Notice of redemption must be sent by the Company or at the Company’s
request, by the Trustee in the name and at the expense of the Company, to Holders whose Notes are
to be redeemed at least 30 days but not more than 60 days before the redemption date.

     (b) The notice of redemption will identify the Notes to be redeemed and will include or state
the following:

interest;

     (iii) the place or places where Notes are to be surrendered for redemption;

     (iv) Notes called for redemption must be so surrendered in order to collect the

     (v) on the redemption date the redemption price will become due and payable on Notes
called for redemption, and interest on Notes called for redemption will cease to accrue on
and after the redemption date;

     (vi) if any Note is redeemed in part, on and after the redemption date, upon
surrender of such Note, new Notes equal in principal amount to the unredeemed portion will
be issued; and

     (vii) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the notice of redemption and that the Holder should rely only on the other
identification numbers printed on the Notes.

     (c) Once notice of redemption is sent to the Holders, Notes called for redemption become due
and payable at the redemption price on the redemption date, and upon surrender of the Notes called
for redemption, the Company shall

38

 

redeem such Notes at the redemption price. Commencing on the
redemption date, Notes redeemed will cease to accrue interest. Upon surrender of any Note redeemed
in part, the Holder will receive a new Note equal in principal amount to the unredeemed portion of
the surrendered Note.

     Section 3.04 . Offer to Purchase. (a) An “Offer to Purchase” means an offer by the Company
to purchase Notes as required by the Indenture. An Offer to Purchase must be made by written offer
(the “offer”) sent to the Holders. The Company will notify the Trustee at least 15 days (or such
shorter period as is acceptable to the Trustee) prior to sending the offer to Holders of its
obligation to make an Offer to Purchase, and the offer will be sent by the Company or, at the
Company’s request, by the Trustee in the name and at the expense of the Company.

by which such amount has been determined pursuant to the Indenture) (the “purchase
amount”);

     (iii) the purchase price, including the portion thereof representing accrued
interest;

     (iv) an expiration date (the “expiration date”) not less than 30 days or more than 60
days after the date of the offer, and a settlement date for purchase (the “purchase date”)
not more than five Business Days after the expiration date;

     (v) information concerning the business of the Company and its Subsidiaries which the
Company in good faith believes will enable the Holders to make an informed decision with
respect to the Offer to Purchase, at a minimum to include

     (A) the most recent annual and quarterly financial statements and
“Management’s Discussion and Analysis of Financial Condition and Results of
Operations” for the Company,

     (viii) each Holder electing to tender a Note pursuant to the offer will be required
to surrender such Note at the place or places specified in the offer prior to the close of
business on the expiration date (such Note being, if the Company or the Trustee so
requires, duly endorsed or accompanied by a duly executed written instrument of transfer);

     (ix) interest on any Note not tendered, or tendered but not purchased by the Company
pursuant to the Offer to Purchase, will continue to accrue;

     (x) on the purchase date the purchase price will become due and payable on each Note
accepted for purchase, and interest on Notes purchased will cease to accrue on and after
the purchase date;

     (xi) Holders are entitled to withdraw Notes tendered by giving notice, which must be
received by the Company or the Trustee not later than the close of business on the
expiration date, setting forth the name of the Holder, the principal amount of the
tendered Notes, the certificate number of the tendered Notes and a statement that the
Holder is withdrawing all or a portion of the tender;

     (xii) (A) if Notes in an aggregate principal amount less than or equal to the
purchase amount are duly tendered and not withdrawn pursuant to the Offer to Purchase, the
Company will purchase all such Notes, and (B) if the Offer to Purchase is for less than
all of the outstanding Notes and Notes in an aggregate principal amount in excess of the
purchase amount are tendered and not withdrawn pursuant to the offer, the Company will
purchase Notes having an aggregate principal amount equal to the purchase amount on a pro
rata basis, with adjustments so that

40

 

     only Notes in denominations of $1,000 in principal
amount and any multiple of $1,000 in excess thereof will be purchased;

     (xiii) if any Note is purchased in part, new Notes equal in principal amount to the
unpurchased portion of the Note will be issued; and

     (xiv) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the offer and that the Holder should rely only on the other identification
numbers printed on the Notes.

     (c) On or prior to the purchase date, the Company will accept tendered Notes for purchase as
required by the Offer to Purchase and deliver to the Trustee all Notes so accepted together with an
Officers’ Certificate specifying which Notes have been accepted for purchase. On the purchase date
the purchase price will become due and payable on each Note accepted for purchase, and interest on
Notes purchased will cease to accrue on and after the purchase date. The Trustee will promptly
return to Holders any Notes not accepted for purchase and send to Holders new Notes equal in
principal amount to any unpurchased portion of any Notes accepted for purchase in part.

     (d) The Company will comply with Rule 14e-1 under the Exchange Act and all other applicable
laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary
to permit such compliance.

Notes, or any redemption or purchase price of the Notes, the Company will deposit with the Trustee
(or Paying Agent) money in immediately available funds sufficient to pay such amounts, provided
that if the Company or any Affiliate of the Company is acting as Paying Agent, it will, on or
before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a
sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as
provided in the Indenture. In each case the Company will promptly notify the Trustee of its
compliance with this paragraph.

41

 

     (b) An installment of principal or interest will be considered paid on the date due if the
Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds on that
date money designated for and sufficient to pay the installment. If the Company or any Affiliate
of the Company acts as Paying Agent, an installment of principal or interest will be considered
paid on the due date only if paid to the Holders.

     (c) The Company agrees to pay interest on overdue principal, and, to the extent lawful,
overdue installments of interest at the rate per annum specified in the Notes.

is specified, by mailing a check to each Holder’s registered address.

     Section 4.02 . Maintenance of Office or Agency. The Company will maintain in the United
States of America, an office or agency where Notes may be surrendered for registration of transfer
or exchange or for presentation for payment and where notices and demands to or upon the Company in
respect of the Notes and the Indenture may be served. The Company hereby initially designates the
Corporate Trust Office of the Trustee as such office of the Company. The Company will 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 to
the Trustee.

     The Company may also from time to time designate one or more other offices or agencies where
the Notes may be surrendered or presented for any of such purposes and may from time to time
rescind such designations. The Company will 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 . Existence. The Company will do or cause to be done all things necessary to

Restricted Subsidiaries in accordance with their respective organizational documents, and the
material rights, licenses and franchises of the Company and each Restricted Subsidiary, provided
that the Company is not required to preserve any such right, license or franchise, or the existence
of any Restricted Subsidiary, if the maintenance or preservation thereof is no longer desirable in
the conduct of the business of the Company and its Restricted

42

 

Subsidiaries taken as a whole; and
provided further that this Section does not prohibit any transaction otherwise permitted by Section
4.13 or Article 5.

     Section 4.04 . Payment of Taxes and other Claims. The Company will pay or discharge, and
cause each of its Subsidiaries to pay or discharge before the same become delinquent (i) all
material taxes, assessments and governmental charges levied or imposed upon the Company or any
Subsidiary or its income or profits or property, and (ii) all material lawful claims for labor,
materials and supplies that, if unpaid, might by law become a Lien upon the property of the Company
or any Subsidiary, other than any such tax, assessment, charge or claim the amount, applicability
or validity of which is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established.

     Section 4.05 . Maintenance of Properties and Insurance. (a) The Company will cause all
properties used or useful in the conduct of its business or the business of any of its Restricted
Subsidiaries to be maintained and kept in good condition, repair and working order as in the
judgment of the Company may be necessary so that the business of the Company and its Restricted
Subsidiaries may be properly and advantageously conducted at all times; provided that nothing in
this Section prevents the Company or any Restricted Subsidiary from discontinuing the use,
operation or maintenance of any of such properties or disposing of any of them, if such
discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of the
business of the Company and its Restricted Subsidiaries taken as a whole.

right of payment to the Notes at least to the extent that the Debt to be
refinanced is subordinated to the Notes,

44

 

     (B) the Average Life of the new Debt is at least equal to the remaining

For purposes of this clause (b): (i) the assumption by the purchaser of Debt or other obligations
(other than Subordinated Debt) of the Company or a Restricted Subsidiary pursuant to a customary
novation agreement, and (ii) instruments or securities received from the purchaser that are
promptly, but in any event within

53

 

60 days of the closing, converted by the Company to cash, to the
extent of the cash actually so received, shall be considered cash received at closing.

     (c) Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Net
Cash Proceeds may be used

     (i) to repay Senior Debt in each case owing to a Person other than the Company or any
Restricted Subsidiary, or

     (ii) to acquire all or substantially all of the assets of a Permitted Business, or a
majority of the Voting Stock of another Person that thereupon becomes a Restricted
Subsidiary engaged in a Permitted Business, or to make capital expenditures or otherwise
acquire long-term assets that are to be used in a Permitted Business; provided further,
that, in the case of this clause (ii), a binding commitment shall be treated as a
permitted application of the Net Cash Proceeds from the date of such commitment if (x)
such acquisition or capital expenditure is consummated within 545 days after receipt by
the Company or any Restricted Subsidiary of the Net Cash Proceeds of any Asset Sale and
(y) if such acquisition or capital expenditure is not consummated within the period set
forth in subclause (x), the Net Cash Proceeds not so applied will be deemed to be Excess
Proceeds (as defined below);

     (d) The Net Cash Proceeds of an Asset Sale not applied pursuant to clause (c) within the time
periods specified therein constitute “Excess Proceeds”. Excess Proceeds of less than $10.0 million
will be carried forward and accumulated. When accumulated Excess Proceeds equals or exceeds $10.0
million, the Company must, within 30 days (or, if the Company is required to make an offer to
purchase any Senior Debt with such proceeds, within 30 days following the completion of such
offer), make an Offer to Purchase Notes having a principal amount equal to

     (i) accumulated Excess Proceeds, multiplied by

     (ii) a fraction (x) the numerator of which is equal to the outstanding principal
amount of the Notes and (y) the denominator of which is equal to the outstanding principal
amount of the Notes and all pari passu Debt that is similarly required to be repaid,
redeemed or tendered for in connection with the Asset Sale,

rounded down to the nearest $1,000. The purchase price for the Notes will be 100% of the principal
amount plus accrued interest to the date of purchase. Upon
completion of the Offer to Purchase, Excess Proceeds will be reset at zero, and any

54

 

Excess Proceeds
remaining after consummation of the Offer to Purchase may be used for any purpose not otherwise
prohibited by the Indenture.

assets, or the rendering of any service with any Affiliate of the Company or any Restricted
Subsidiary (a “Related Party Transaction”), except upon fair and reasonable terms no less favorable
to the Company or the Restricted Subsidiary than could be obtained in a comparable arm’s-length
transaction with a Person that is not an Affiliate of the Company.

     (b) Any Related Party Transaction or series of Related Party Transactions with an aggregate
value in excess of $5.0 million must first be approved by a majority of the Board of Directors who
are disinterested in the subject matter of the transaction pursuant to a Board Resolution delivered
to the Trustee. Prior to entering into any Related Party Transaction or series of Related Party
Transactions with an aggregate value in excess of $15.0 million, the Company must in addition
obtain and deliver to the Trustee a favorable written opinion from a nationally recognized
investment banking firm as to the fairness of the transaction to the Company and its Restricted
Subsidiaries from a financial point of view.

direct or indirect parent of the Company; provided, however, that such parent shall have
no material liabilities and no material assets other than cash, Cash Equivalents and the
Capital Stock of the Company or intermediate parent companies (which themselves have no
other material assets or liabilities) and such merger is otherwise in compliance with the
terms of the Indenture and effected for a bona fide business purpose;

     (ii) any reasonable fees, advances and compensation (including incentive
compensation) provided to, and indemnity provided on behalf of, officers, directors and
employees of NFC Castings, ACP Holding, the Company and its Restricted Subsidiaries as

compensation or benefit plans or arrangements entered into in the ordinary course of
business;

     (v) transactions pursuant to any contract or agreement in effect on the date of the
Indenture, as amended, modified or replaced from time to time so long as the amended,
modified or new agreements, taken as a whole, are no less favorable to the Company and its
Restricted Subsidiaries than those in effect on the date of the Indenture;

     (vi) payment of principal of, and interest (including Deferred Interest Payments) on,
the Notes held by Affiliates;

     (vii) Debt permitted pursuant to paragraph (b)(ii) under Section 4.06;

and 11% Senior Secured Notes due 2010 owned by any Permitted Holders on the same terms and
conditions as repurchases from other holders thereof, including payment of all related
premiums and consent fees;

     (x) any redemption of the Notes at a price not greater than 100% of the principal
amount thereof; or

     (xi) any transaction or series of related transactions with any customer or supplier
in the ordinary course of business that are on terms no less favorable than could be
obtained in a comparable arms-length transaction with a Person that is not an Affiliate of
the Company, which transaction or series of transactions, if their aggregate value exceeds
$5.0 million, are approved by a majority of the Board of Directors who are disinterested
in the subject matter thereof.

     Section 4.15 . Line of Business. The Company will not, and will not permit any of its
Restricted Subsidiaries, to engage in any business other than a Permitted Business, except to an
extent that so doing would not be material to the Company and its Restricted Subsidiaries, taken as
a whole.

56

 

     Section 4.16 . Designation of Restricted and Unrestricted Subsidiaries. (a) The Board of
Directors may designate any Subsidiary (including a newly

Restricted Subsidiary.

     (ii) At the time of designation, the designation would be permitted under Section

Once so designated the Subsidiary will remain an Unrestricted Subsidiary, subject to paragraph (b).

     (b) (i) A Subsidiary previously designated an Unrestricted Subsidiary which fails to meet the
qualifications set forth in paragraph (a) will be deemed to become at that time a Restricted

Restricted Subsidiary if the designation would not cause a Default.

held by it will be deemed Incurred at that time, and all Liens on property of the Company

will accept the filing, file a copy of all of the information and reports referred to in clauses
(i) and (ii) with the Commission for public availability within the time periods specified in the
Commission’s rules and regulations for a non-accelerated filer. In addition, the Company will make

examination, any Default has come to their attention and, if such a Default has come to their
attention, specifying the nature and period of the existence thereof; provided, however, that if
the Company’s independent public accountants are unable to provide such written statement due to

to the Company and to the Trustee may waive all past defaults and rescind and annul a declaration
of acceleration and its consequences if

     (i) all existing Events of Default, other than the nonpayment of the principal of,
premium, if any, and interest on the Notes that have

64

 

become due solely by the declaration
of acceleration, have been cured or waived, and

     (ii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

     Section 6.03 . Other Remedies. If an Event of Default occurs and is continuing, the Trustee
may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding
at law or in equity to collect the payment of principal of and interest on the Notes or to enforce
the performance of any provision of the Notes or the Indenture. The Trustee may maintain a
proceeding even if it does not possess any of the Notes or does not produce any of them in the
proceeding.

     Section 6.04 . Waiver of Past Defaults. Except as otherwise provided in Sections 6.02, 6.07
and 9.02, the Holders of a majority in principal amount of the outstanding Notes may, by notice to
the Trustee, waive an existing Default and its
consequences. Upon such waiver, the Default will cease to exist, and any Event of Default
arising therefrom will be deemed to have been cured, but no such waiver will extend to any
subsequent or other Default or impair any right consequent thereon.

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

     Section 6.06 . Limitation on Suits. A Holder may not institute any proceeding, judicial or
otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under the Indenture or the Notes, unless:

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

     (b) Holders of at least 25% in aggregate principal amount of outstanding Notes have made
written request to the Trustee to institute proceedings in respect of the Event of Default in its
own name as Trustee under the Indenture;

65

 

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

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

     (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the
outstanding Notes have not given the Trustee a direction that is inconsistent with such written
request.

     Section 6.07 . Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive payment of principal of or interest on its
Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such
payment on or after such respective dates, may not be impaired or affected without the consent of
that Holder.

     Section 6.08 . Collection Suit by Trustee. If an Event of Default in payment of principal or
interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust for the whole amount of
principal and accrued interest remaining unpaid, together with interest on overdue principal and,
to the extent lawful, overdue installments of interest, in each case at the rate specified in the
Notes, and such further amount as is sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel and any other amounts due the Trustee hereunder.

     Section 6.09 . Trustee May File Proofs of Claim. The Trustee may file proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders
allowed in any judicial proceedings relating to the Company or any Guarantor or their respective
creditors or property, and is entitled and empowered to collect, receive and distribute any money,
securities or other property payable or deliverable upon conversion or exchange of the Notes or
upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder to make
such payments to the Trustee and, if the Trustee consents 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 agent and counsel, and any other amounts
due the Trustee hereunder. Nothing in the Indenture will be deemed to empower the Trustee to
authorize or

66

 

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

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

     First: to the Trustee for all amounts due hereunder;

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

     Third: to the Company or as a court of competent jurisdiction may direct.

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

     Section 6.11 . Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, any Guarantors,
the Trustee and the Holders will be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Company, any Guarantors, the Trustee and
the Holders will continue as though no such proceeding had been instituted.

     Section 6.12 . Undertaking for Costs. In any suit for the enforcement of any right or remedy
under the Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an
undertaking to pay the costs of the suit, and the court may assess reasonable costs, including
reasonable attorneys fees and expenses, against any party litigant (other than the Trustee) in the
suit having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or
interest on any Note on the respective due dates, or a suit by Holders of more than 10% in
principal amount of the outstanding Notes.

     Section 6.13 . Rights and Remedies Cumulative. No right or remedy conferred or reserved to
the Trustee or to the Holders under this Indenture is

67

 

intended to be exclusive of any other right
or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in
addition to every other right and remedy hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not
prevent the concurrent assertion or exercise of any other right or remedy.

     Section 6.14 . Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder to exercise any right or remedy accruing upon any Event of Default will impair any such
right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

     Section 6.15 . Waiver of Stay, Extension or Usury Laws. The Company and each Guarantor
covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension
law or any usury law or other law that would prohibit or forgive the Company or the Guarantor from
paying all
or any portion of the principal of, or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or that may affect the covenants or the performance
of the Indenture. The Company and each Guarantor hereby expressly waives, to the extent that it
may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

The Trustee

     Section 7.01 . General. (a) The duties and responsibilities of the Trustee are as provided
by the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every
provision of the Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee is subject to this Article.

     (b) Except during the continuance of an Event of Default, the Trustee need perform only those
duties that are specifically set forth in the Indenture and no others, and no implied covenants or
obligations will be read into the Indenture against the Trustee. In case an Event of Default has
occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the
Indenture,

68

 

and use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     (c) No provision of the Indenture shall be construed to relieve the Trustee from liability for
its own negligent action, its own negligent failure to act or its own willful misconduct.

     Section 7.02 . Certain Rights of Trustee. Subject to Trust Indenture Act Sections 315(a)
through (d):

     (a) The Trustee may conclusively rely, and will be fully protected in acting or refraining
from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the document, but, in the
case of any document which is specifically required to be furnished to the Trustee pursuant to any
provision hereof, the Trustee shall examine the document to determine whether it conforms to the
requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein). The Trustee, in its discretion, may make further
inquiry or investigation into such facts or matters as it sees fit.

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel conforming to Section 12.05 and the Trustee will not be liable for any
action it takes or omits to take in good faith in reliance on the certificate or opinion.

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

     (d) The Trustee will be under no obligation to exercise any of the rights or powers vested in
it by the Indenture at the request or direction of any of the Holders, unless such Holders have
offered to the Trustee security or indemnity reasonably satisfactory to it against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or direction.

     (e) The Trustee will not be liable for any action it takes or omits to take in good faith that
it believes to be authorized or within its rights or powers or for any action it takes or omits to
take in accordance with the direction of the Holders in accordance with Section 6.05 relating to
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under the Indenture.

69

 

     (f) The Trustee may consult with counsel, and the advice of such counsel or any Opinion of
Counsel will be full and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.

     (g) No provision of the Indenture will require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of its duties hereunder, or in the
exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss,
liability or expense.

     (h) In no event shall the Trustee be responsible or liable for special, indirect or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     (i) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any
event which is in fact such a default is received by the Trustee at the Corporate Trust Office of
the Trustee, and such notice references the Securities and this Indenture.

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

     Section 7.03 . Individual Rights of Trustee. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the
same with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and
311. For purposes of Trust Indenture Act Section 311(b)(4) and (6):

     (a) “cash transaction” means any transaction in which full payment for goods or securities
sold is made within seven days after delivery of the goods or securities in currency or in checks
or other orders drawn upon banks or bankers and payable upon demand; and

     (b) “self-liquidating paper” means any draft, bill of exchange, acceptance or obligation which
is made, drawn, negotiated or incurred for the purpose of financing the purchase, processing,
manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by
documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or
the receivables or proceeds arising from the sale of the goods, wares or

70

 

merchandise previously
constituting the security, provided the security is received by the Trustee simultaneously with the
creation of the creditor relationship arising from the making, drawing, negotiating or incurring of
the draft, bill of exchange, acceptance or obligation.

     Section 7.04 . Trustee’s Disclaimer. The Trustee (a) makes no representation as to the
validity or adequacy of the Indenture or the Notes, (b) is not accountable for the Company’s use or
application of the proceeds from the Notes and (c) is not responsible for any statement in the
Notes other than its certificate of authentication.

     Section 7.05 . Notice of Default. If any Default occurs and is continuing and is known to
the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it
occurs, unless the Default has been cured; provided that, except in the case of a default in the
payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so
long as a trust committee of directors of the Trustee in good faith determines that withholding the
notice is in the interest of the Holders. Notice to Holders under this Section will be given in
the manner and to the extent provided in Trust Indenture Act Section 313(c).

     Section 7.06 . Reports by Trustee to Holders. Within 60 days after each May 15, beginning
with May 15, 2007, the Trustee will mail to each Holder, as provided in Trust Indenture Act Section
313(c), a brief report dated as of such May 15, if required by Trust Indenture Act Section 313(a),
and file such reports
with each stock exchange upon which its Notes are listed and with the Commission as required
by Trust Indenture Act Section 313(d).

     Section 7.07 . Compensation And Indemnity. (a) The Company will pay the Trustee
compensation as agreed upon in writing for its services. The compensation of the Trustee is not
limited by any law on compensation of a Trustee of an express trust. The Company will reimburse
the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances
incurred or made by the Trustee, including the reasonable compensation and expenses of the
Trustee’s agents and counsel.

     (b) Each of the Company and the Guarantors, jointly and severally, will indemnify the Trustee
for, and hold it harmless against, any loss, claim, damage or liability or expense incurred by it
without negligence or bad faith on its part arising out of or in connection with the acceptance or
administration of the Indenture and its duties under the Indenture and the Notes, including the
costs and expenses of defending itself against any claim or liability and of complying with any
process served upon it or any of its officers in connection with the exercise or performance of any
of its powers or duties under the Indenture and the Notes.

71

 

     (c) To secure the Company’s payment obligations in this Section, the Trustee will have a lien
prior to the Notes on all money or property held or collected by the Trustee, in its capacity as
Trustee, except money or property held in trust to pay principal of, and interest on, particular
Notes. The benefits of this Section shall survive the termination of this Indenture.

     Section 7.08 . Replacement of Trustee. (a)(i) The Trustee may resign at any time by written
notice to the Company.

     (ii) The Holders of a majority in principal amount of the outstanding Notes may remove
the Trustee by written notice to the Trustee and the Company.

     (iii) If the Trustee is no longer eligible under Section 7.10 or in the circumstances
described in Trust Indenture Act Section 310(b), any Holder that satisfies the
requirements of Trust Indenture Act Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     (iv) The Company may remove the Trustee if: (A) the Trustee is no longer eligible
under Section 7.10; (B) the Trustee is adjudged a bankrupt or an insolvent; (C) a receiver
or other public officer takes charge of the Trustee or its property; or (D) the Trustee
becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     (b) If the Trustee has been removed by the Holders, Holders of a majority in principal amount
of the Notes may appoint a successor Trustee with the consent of the Company. Otherwise, if the
Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the
Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its
written acceptance within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of a majority in principal amount of the outstanding Notes may
petition at the expense of the Company any court of competent jurisdiction for the appointment of a
successor Trustee.

     (c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the
retiring Trustee and to the Company, (i) the retiring Trustee will transfer, upon payment of its
fees and expenses hereunder, all property held by it as Trustee to the successor Trustee, subject
to the lien provided for in Section 7.07, (ii) the resignation or removal of the retiring Trustee
will become

72

 

effective, and (iii) the successor Trustee will have all the rights, powers and duties
of the Trustee under the Indenture. Upon request of any successor Trustee, the Company will
execute any and all instruments for fully and vesting in and confirming to the successor Trustee
all such rights, powers and trusts. The Company will give notice of any resignation and any
removal of the Trustee and each appointment of a successor Trustee to all Holders, and include in
the notice the name of the successor Trustee and the address of its Corporate Trust Office.

     (d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

     (e) The Trustee agrees to give the notices provided for in, and otherwise comply with, Trust
Indenture Act Section 310(b).

     Section 7.09 . Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust business to, another
corporation or national banking association, the resulting, surviving or transferee corporation or
national banking association without any further act will be the successor Trustee with the same
effect as if the successor Trustee had been named as the Trustee in the Indenture.

     Section 7.10 . Eligibility. The Indenture must always have a Trustee that satisfies the
requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at
least $25,000,000 as set forth in its most recent published annual report of condition.

     Section 7.11 . Money Held in Trust. The Trustee will not be liable for interest on any money
received by it except as it may agree with the Company. Money held in trust by the Trustee need
not be segregated from other funds except to the extent required by law and except for money held
in trust under Article 8.

ARTICLE 8

will be discharged. Thereafter, the Trustee upon request will acknowledge in writing the discharge
of the Company’s obligations under the Notes and the Indenture except for the surviving obligations
specified above.

     Section 8.03 . Covenant Defeasance. After the 123rd day following the deposit referred to in
clause (a) of Section 8.02, the Company’s obligations in Sections 4.06 through 4.17, inclusive and

     Except as specifically stated above, none of the Company’s obligations under the Indenture
will be discharged.

     Section 8.04 . Application of Trust Money. Subject to Section 8.05, the Trustee will hold in

except to the extent required by law.

     Section 8.05 . Repayment to Company. Subject to Sections 7.07, 8.01, 8.02 and 8.03, the
Trustee will promptly pay to the Company upon request any excess money held by the Trustee at any
time and thereupon be relieved from all liability with respect to such money. The Trustee will pay
to the Company upon request any money held for payment with respect to the Notes that remains
unclaimed for two years, provided that before making such payment the Trustee may at the expense of
the Company publish once in a newspaper of general circulation in New York City, or send to each
Holder entitled to such money, notice that the money remains unclaimed and that after a date
specified in the notice (at least 30 days after the date of the publication or notice) any
remaining unclaimed balance of money will be repaid to the Company. After payment to the

76

 

Company,
Holders entitled to such money must look solely to the Company for payment, unless applicable law
designates another Person, and all liability of the Trustee with respect to such money will cease.

     Section 8.06 . Reinstatement. If and for so long as the Trustee is unable to apply any money
or U.S. Government Obligations held in trust pursuant to Section 8.01, 8.02 or 8.03 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 obligations under
the Indenture and the Notes will be reinstated as though no such deposit in trust had been made.
If the Company makes any payment of principal of or interest on any Notes because of the
reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes
to receive such payment from the money or U.S. Government Obligations held in trust.

ARTICLE 9

Amendments, Supplements and Waivers

     Section 9.01 . Amendments Without Consent of Holders. The Company and the Trustee may amend
or supplement the Indenture and/or the Notes without notice to or the consent of any Noteholder

     (a) to cure any ambiguity, defect or inconsistency;

     (b) to comply with Article 5;

     (c) to comply with any requirements of the Commission in connection with the qualification of
the Indenture under the Trust Indenture Act;

     (d) to evidence and provide for the acceptance of an appointment hereunder by a successor
Trustee;

     (e) to provide for uncertificated Notes in addition to or in place of certificated Notes,
provided that the uncertificated Notes are issued in registered
form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated
Notes are described in Section 163(f)(2)(B) of the Code;

     (f) to provide for any Guarantee of the Notes, to secure the Notes or to confirm and evidence
the release, termination or discharge of any Guarantee of or Lien securing the Notes when such
release, termination or discharge is permitted by the Indenture;

     (g) to provide for or confirm the issuance of Additional Notes; or

77

 

     (h) to make any other change that does not materially and adversely affect the rights of any
Holder.

     Section 9.02 . Amendments With Consent of Holders. (a) Except as otherwise provided in
Sections 6.02, 6.04 and 6.07 or paragraph (b), the Company and the Trustee may amend or supplement
the Indenture, and/or the Notes with the written consent of the Holders of a majority in principal
amount of the outstanding Notes and the Holders of a majority in principal amount of the
outstanding Notes may waive future compliance by the Company with any provision of the Indenture or
the Notes. Notwithstanding the foregoing or anything to the contrary in the Indenture, so long as
Tontine holds at least 25% in aggregate principal amount of the Notes, Tontine’s consent shall be
required for any amendment or modification to, or waiver of, (i) the provisions in Paragraph 1 of
the Notes providing for the inclusion of Notes owned by any Affiliate of the Company for purposes
of determining whether the Holders of the requisite principal amount of the outstanding Notes have
given or taken any request, demand, authorization, direction, notice, consent, waiver or other
action hereunder or under the Notes, and (ii) the last sentence of Paragraph 1 of the Notes
requiring the consent of Tontine to all requests, demands, authorizations, directions, notices,
consents, waivers and other actions hereunder and under the Notes.

     (b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder
affected, an amendment or waiver may not

     (i) reduce the principal amount of or change the Stated Maturity of any installment
of principal of any Note,

     (ii) reduce the rate of or change the Stated Maturity of any interest payment on any
Note,

     (iii) reduce the amount payable upon the redemption of any Note or change the time of
any mandatory redemption or, in respect of an optional redemption, the times at which any
Note may be redeemed or, once notice of redemption has been given, the time at which it
must thereupon be redeemed,

     (iv) after the time an Offer to Purchase is required to have been made, reduce the
purchase amount or purchase price, or extend the latest expiration date or purchase date
thereunder,

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

78

 

     (vi) impair the right of any Holder of Notes to receive any principal payment or
interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or to
institute suit for the enforcement of any such payment,

     (vii) make any change in the percentage of the principal amount of the Notes required
for amendments or waivers,

     (viii) modify or change any provision of the Indenture affecting the ranking of the
Notes or any Note Guaranty in a manner adverse to the Holders of the Notes,

     (ix) make any change in any Note Guaranty that would adversely affect the
Noteholders, or

     (x) [Reserved]

provided that the provisions of Section 4.12 and Section 4.13 may, except as provided above, be
amended or waived with the consent of Holders holding not less than 66 2/3% in aggregate principal
amount of the Notes.

     (c) It is not necessary for Noteholders to approve the particular form of any proposed
amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

     (d) An amendment, supplement or waiver under this Section will become effective on receipt by
the Trustee of written consents from the Holders of the requisite percentage in principal amount of
the outstanding Notes. After an amendment, supplement or waiver under this Section becomes
effective, the Company will send to the Holders affected thereby a notice briefly describing the
amendment, supplement or waiver. The Company will send supplemental indentures to Holders upon
request. Any failure of the Company to send such notice, or any defect therein, will not, however,
in any way impair or affect the validity of any such supplemental indenture or waiver.

     (e) An amendment may not effect any change that adversely affects the rights of any holder of
Senior Debt under Article 11 then outstanding unless such holder of Senior Debt, or a
representative for such holder, consents to such change.

     Section 9.03 . Effect of Consent. (a) After an amendment, supplement or waiver becomes
effective, it will bind every Holder unless it is of the type requiring the consent of each Holder
affected. If the amendment, supplement or waiver is of the type requiring the consent of each
Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it

79

 

and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting
Holder.

     (b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require
the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of
the changed terms on the Note and return it to the Holder, or exchange it for a new Note that
reflects the changed terms. The Trustee may also place an appropriate notation on any Note
thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not
affected by any failure to annotate or exchange Notes in this fashion.

     Section 9.04 . Trustee’s Rights and Obligations. The Trustee shall be provided with, and
will be fully protected in relying upon, an Opinion of Counsel stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by
the Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the
amendment, supplement or waiver so long as the same does not adversely affect the rights of the
Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver
that affects the Trustee’s own rights, duties or immunities under the Indenture.

     Section 9.05 . Conformity With Trust Indenture Act. Every supplemental indenture executed
pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

     Section 9.06 . Payments for Consents. Neither the Company nor any of its Subsidiaries or
Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by way
of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration
is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree
to amend such term or provision within the time period set forth in the solicitation documents
relating to the consent, waiver or amendment.

ARTICLE 10

Guaranties

     Section 10.01 . The Guaranties. Subject to the provisions of this Article, each Guarantor
hereby irrevocably and unconditionally guarantees, jointly and severally, to the Holders and to the
Trustee the full and punctual payment
(whether at Stated Maturity, upon redemption, purchase pursuant to an Offer to Purchase or
acceleration, or otherwise) of the principal of, premium, if any, and interest on, and all other
amounts payable under, each Note, and the full and

80

 

punctual payment of all other amounts payable by
the Company under the Indenture. Upon failure by the Company to pay punctually any such amount,
each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner
specified in the Indenture. The obligations of each Guarantor under its Note Guaranty are junior
and subordinated in right of payment to the Senior Debt of such Guarantor in the same manner and to
the same extent as the Notes are subordinated to Senior Debt of the Company.

     Section 10.02 . Guaranty Unconditional. The obligations of each Guarantor hereunder are
unconditional and absolute and, without limiting the generality of the foregoing, will not be
released, discharged or otherwise affected by:

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

     (2) any modification or amendment of or supplement to the Indenture, or any Note;

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

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

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

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

81

 

     Section 10.03 . Discharge; Reinstatement. Each Guarantor’s obligations hereunder will remain
in full force and effect until the principal of, premium, if any, and interest on the Notes and all
other amounts payable by the Company under the Indenture have been paid in full. If at any time
any payment of the principal of, premium, if any, or interest on any Note or any other amount
payable by the Company under the Indenture is rescinded or must be otherwise restored or returned
upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guarantor’s
obligations hereunder with respect to such payment will be reinstated as though such payment had
been due but not made at such time.

     Section 10.04 . Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as well as any
requirement that at any time any action be taken by any Person against the Company or any other
Person.

     Section 10.05 . Subrogation and Contribution. Upon making any payment with respect to any
obligation of the Company under this Article, the Guarantor making such payment will be subrogated
to the rights of the payee against the Company with respect to such obligation, provided that the
Guarantor may not enforce either any right of subrogation, or any right to receive payment in the
nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so
long as any amount payable by the Company hereunder or under the Notes remains unpaid.

     Section 10.06 . Stay of Acceleration. If acceleration of the time for payment of any amount
payable by the Company under the Indenture or the Notes is stayed upon the insolvency, bankruptcy
or reorganization of the Company, all such amounts otherwise subject to acceleration under the
terms of the Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by
the Trustee or the Holders.

     Section 10.07 . Limitation on Amount of Guaranty. Notwithstanding anything to the contrary
in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that
it is the intention of all such parties that the Note Guaranty of such Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the
Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each
Guarantor under its Note Guaranty are limited to the maximum amount that would not render the
Guarantor’s obligations subject to avoidance under applicable fraudulent transfer provisions of the
United States Bankruptcy Code or any comparable provision of state law.

82

 

     Section 10.08 . Execution and Delivery of Guaranty. The execution by each Guarantor of the
Indenture (or a supplemental indenture substantially in the
form of Exhibit B) evidences the Note Guaranty of such Guarantor, whether or not the person
signing as an officer of the Guarantor still holds that office at the time of authentication of any
Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the
Note Guaranty set forth in the Indenture on behalf of each Guarantor.

     Section 10.09 . Release of Guaranty. The Note Guaranty of a Guarantor will terminate upon

     (a) a sale or other disposition (including by way of consolidation or merger) of the Guarantor
or the sale or disposition of all or substantially all the assets of the Guarantor (in each case
other than to the Company or a Restricted Subsidiary) otherwise permitted by the Indenture,

     (b) the designation in accordance with the Indenture of the Guarantor as an Unrestricted
Subsidiary, or

     (c) defeasance or discharge of the Notes, as provided in Article 8.

     Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of
Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in
order to evidence the release of the Guarantor from its obligations under its Note Guaranty.

ARTICLE 11

Subordination

     The provisions of Sections 11.01 through 11.14, as written, define the subordination of the
Notes, as obligations of the Company, with respect to Senior Debt of the Company and Permitted
Junior Securities, as defined for the Company, only. All such provisions shall also be deemed to
apply in the same way (mutatis mutandis) to each Guarantor, if any, and its Note Guaranty, with
appropriate corresponding references to the Senior Debt of, and Permitted Junior Securities with
respect to, such Guarantor.

     Section 11.01 . Agreement to Subordinate. The Debt evidenced by the Notes is subordinated in
right of payment, to the extent and in the manner provided in the Indenture, to the prior payment
in full of all Senior Debt. The subordination provisions are for the benefit of and enforceable by
the holders of Senior Debt and their representatives.

83

 

     Section 11.02 . Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of
the assets of the Company to creditors upon a total or partial liquidation or a total or partial
dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership, assignment
for the benefit of creditors or
similar proceeding relating to the Company or its property, in each case whether voluntary or
involuntary, domestic or foreign:

     (1) holders of Senior Debt are entitled to receive payment in full in cash of all
Obligations in respect of Senior Debt, including all interest accrued or accruing on
Senior Debt after the commencement of any bankruptcy, insolvency or reorganization or
similar case or proceeding at the contract rate (including, without limitation, any
contract rate applicable upon default) specified in the relevant documentation, whether or
not the claim for the interest is allowed as a claim in the case or proceeding with
respect to the Senior Debt (only such payment constituting “payment in full”) before
Holders will be entitled to receive any payment on the Notes; and

     (2) until the Senior Debt is paid in full, any distribution to which Noteholders
would be entitled but for these subordination provisions shall instead be made to holders
of Senior Debt as their interests may appear.

     In order to enable the holders of Senior Debt to enforce their rights hereunder in any of the
aforesaid actions or proceedings, such holders, or their representatives, are hereby irrevocably
authorized in their discretion, to the extent that the Trustee does not do so at least 30 days
before the expiration of the time to do so, to file and vote such proofs of claim in respect of the
Debt evidenced by the Notes as they deems appropriate, and to collect any and all dividends or
other payments or disbursements made thereon in whatever form the same may be paid or issued for
application ratably among the holders of Senior Debt. The holders of Senior Debt and their
representatives are hereby authorized to demand, sue for, collect and receive each of the aforesaid
payments and distributions and give acquittance therefore, and to take such other actions as they
deem necessary or advisable to enforce said rights.

     The Trustee and each Holder agrees not to initiate, prosecute or participate in any claim,
action, or other proceeding challenging the enforceability, validity, perfection or priority of the
Senior Debt or any liens or security interests securing the Senior Debt.

     The Trustee and each Holder further agrees that during any such action or proceeding (a) this
Article 11 shall be applicable and shall govern the relative rights and priorities of the holders
of Senior Debt and the Trustee and the Holders of the Debt evidenced by the Notes even if all or
part of the Senior Debt or any

84

 

liens or security interests securing the Senior Debt are
subordinated, set aside, avoided, invalidated or disallowed in connection with any such action or
proceeding, and Article 11 shall be reinstated if at any time any payment of the Senior Debt is
rescinded or must otherwise be returned by any holder of Senior Debt, (b) the holders of Senior
Debt may consent to the use of cash collateral by the Company or any Restricted Subsidiary or
provide financing to the Company
or any Restricted Subsidiary on such terms and conditions and in such amounts as they
determine, (c) they shall not object to, or oppose, a sale or other disposition of property
securing the Senior Debt and (d) any holder of Senior Debt may elect to apply Section 1111(b)(2) of
the United States Bankruptcy Code to all or any part of the Senior Debt.

     Section 11.03 . Default on Designated Senior Debt. (a) Notwithstanding anything to the
contrary contained in this Indenture or the Notes, neither the Company nor any Restricted
Subsidiary may make, and neither the Trustee or any Holder may accept, any payment with respect to
the Debt evidenced by the Notes other than (i) regularly scheduled payments of interest in respect
of the Notes on a non-accelerated basis, (ii) regularly scheduled payments of principal in respect
of the Notes on a non-accelerated basis, (iii) payments of indemnities, costs and expenses
reimbursable by the Company and the Restricted Subsidiaries pursuant to the terms of the Notes and
Indenture, (iv) payments set forth in Section 11.10 and (v) other payments, including payments of
Deferred Interest Payments, that would not violate the provisions of any Designated Senior Debt.

     (b) The Company shall not pay any amount with respect to the Notes or make any deposit
pursuant to Article 8 and shall not repurchase, redeem or otherwise retire any Notes (collectively,
“pay the Notes”) if at the time any Designated Senior Debt has not been paid when due, whether at
maturity, upon redemption or mandatory repurchase, acceleration, or otherwise, and such payment
default has not been cured or waived.

     (c) During the continuance of any other default with respect to any Designated Senior Debt
pursuant to which the maturity thereof may be accelerated, the Company may not pay the Notes for a
period (a “Payment Blockage Period”)

     (1) commencing upon the receipt by the Company and the Trustee of written notice of
default from the holders of any Designated Senior Debt specifying an election to effect a
Payment Blockage Period (a “Blockage Notice”) and

     (2) ending 179 days thereafter (or earlier if the Payment Blockage Period is
terminated (i) by written notice to the Trustee and the Company from the Person that gave
the Blockage Notice, (ii) by

85

 

repayment in full of such Senior Debt or (iii) because the
default giving rise to the Blockage Notice is no longer continuing).

Subject to the preceding paragraph, unless the holders of such Senior Debt have accelerated the
maturity of such Senior Debt, the Company may resume payments on the Notes after the Payment
Blockage Period.

     (d) Not more than an aggregate of 179 days of Payment Blockage Periods may exist in any
consecutive 360-day period, irrespective of the number of defaults with respect to Senior Debt
during such period. No default which existed or was continuing on the date of the commencement of
any Payment Blockage Period with respect to the Senior Debt whose holders initiated the Payment
Blockage Period may be made the basis of the commencement of a subsequent Payment Blockage Period
by the holders of such Senior Debt, whether or not within a period of 360 consecutive days, unless
the default has been cured or waived for a period of not less than 60 consecutive days.

     Section 11.04 . When Distribution Must Be Paid Over. If a payment or other distribution is
made to Noteholders that because of these subordination provisions should not have been made to
them, the Noteholders that receive the distribution shall hold it in trust for holders of Senior
Debt and pay it over to them as their interests may appear.

     Section 11.05 . Subrogation. A distribution made under these subordination provisions to
holders of Senior Debt which otherwise would have been made to Noteholders is not, as between the
Company and Noteholders, a payment by the Company on Senior Debt. After all Senior Debt is paid in
full and until the Notes are paid in full, Noteholders will be subrogated to the rights of holders
of Senior Debt to receive payments in respect of Senior Debt. Payments to holders of Senior Debt
as a result of those provisions do not constitute, as between the Company and the Noteholders,
payments by the Company on the Notes.

     Section 11.06 . Relative Rights; Subordination Not to Prevent Events of Default or Limit
Right to Accelerate. These subordination provisions define the relative rights of Noteholders and
holders of Senior Debt and do not impair, as between the Company and Noteholders, the obligation of
the Company, which is absolute and unconditional, to pay principal of and interest on the Notes in
accordance with their terms. The failure to make a payment pursuant to the Notes by reason of
these subordination provisions does not prevent the occurrence of a Default, nor do these
subordination provisions have any effect on the right of the Noteholders or the Trustee to
accelerate the maturity of the Notes upon an Event of Default or prevent the Trustee or any
Noteholder from exercising its available

86

 

remedies upon a Default, subject to the rights of holders
of Senior Debt to receive distributions otherwise payable to Noteholders.

     Section 11.07 . Subordination May Not Be Impaired By Company. No right of any holder of
Senior Debt to enforce the subordination of the Notes will be impaired by any act or failure to act
by the Company, any Subsidiary, Trustee or Holder or by any of their failure to comply with the
Indenture.

     Section 11.08 . Rights of Trustee. (a) The Trustee may continue to make payments on the
Notes and will not be charged with knowledge of the existence
of facts that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, the Trustee receives notice satisfactory to it
from the Company or a holder of Senior Debt that payments may not be made under this Article.

     (b) The Trustee in its individual or any other capacity may hold Senior Debt with the same
rights, including rights under this Article, it would have if it were not Trustee. Nothing in this
Article applies to claims of, or payments to, the Trustee under or pursuant to Section 7.07.

     Section 11.09 . Distributions and Notices to, and Notices and Consents by, Representatives of
Holders of Senior Debt. Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their representative (if any).
If there is a representative acting for the holders of any Senior Debt pursuant to the agreements
governing such Senior Debt, notices or consents under the Indenture from holders of such Senior
Debt may be given only by their representative. If payment of the Notes is accelerated because of
an Event of Default, the Company shall, as more fully set out in Section 6.02, promptly notify the
holders of Senior Debt of such acceleration. The Company shall promptly notify the holders of the
Senior Debt of any facts known to the Company that would cause a payment with respect to the Notes
to violate this Article 11.

     Section 11.10 . Trust Moneys Not Subordinated; Payments in Permitted Junior Securities.
Notwithstanding anything to the contrary,

     (i) payments from money or U.S. Government Obligations held by the Trustee in trust
under Article 8 (after passage of the 123-day period referred to therein, if relevant) and

     (ii) distributions to Noteholders in the form of Permitted Junior Securities of the
Company

87

 

are not subordinated to the prior payment of any Senior Debt or otherwise subject to these
subordination provisions, and none of the Noteholders will be obligated to pay over any such
payments or distributions to any holder of Senior Debt.

     Section 11.11 . Trustee Entitled to Rely. For the purpose of ascertaining the outstanding
amount of Senior Debt, the holders thereof, and all other information relevant to making any
payment or distribution to holders of Senior Debt pursuant to this Article, the Trustee and the
Noteholders are entitled to rely upon an order or decree of a court of competent jurisdiction in
which any proceedings of the nature referred to in Section 11.02 are pending, a certificate of the
liquidating trustee or other Person making a payment or distribution to the Trustee or to the
Noteholders, or information provided by the holders of Senior Debt. The Trustee may defer any
payment or distribution pending receipt of
evidence or instructions satisfactory to it or a judicial determination regarding the rights
of parties to receive the payment or distribution.

     Section 11.12 . Trustee to Effectuate Subordination. Each Noteholder by accepting a Note
authorizes and directs the Trustee on behalf of the Noteholder to take such action as may be
necessary or appropriate to acknowledge or effectuate the subordination between the Noteholders and
the holders of Senior Debt as provided in this Article and appoints the Trustee as attorney-in-fact
for any and all such purposes, including for the purpose of filing a claim in any proceedings of
the nature referred to in Section 11.02.

     Section 11.13 . Trustee Not Fiduciary for Holders of Senior Debt. The Trustee will not be
deemed to owe any fiduciary duty to the holders of Senior Debt and will not be liable to any such
holders if it mistakenly pays over or distributes to Noteholders, or to the Company or any other
Person, any money or assets to which holders of Senior Debt are entitled by virtue of this Article
unless due to the Trustee’s gross negligence or wilfull misconduct.

     Section 11.14 . Reliance by Holder of Senior Debt on Subordination Provisions; No Waiver.
(a) Each Noteholder by accepting a Note acknowledges and agrees that these subordination provisions
are, and are intended to be, an inducement and a consideration to each holder of Senior Debt,
whether created or acquired before or after the issuance of the Notes, to acquire or to hold such
Senior Debt, and each holder of Senior Debt will be deemed conclusively to have relied on these
subordination provisions in acquiring and holding such Senior Debt.

     (b) The holders of Senior Debt may, at any time and from time to time, without the consent of
or notice to the Trustee or the Holders of the Notes, without incurring any liability or
responsibility to the Holders of the Notes, and

88

 

without impairing the rights of holders of Senior
Debt under these subordination provisions, do any of the following:

     (1) change the manner, place or terms of payment or extend the time of payment of, or
renew or alter, Senior Debt or any instrument evidencing the same or any agreement under
which Senior Debt is outstanding or secured;

     (2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt;

     (3) release any Person liable in any manner for the payment of Senior Debt; or

     (4) exercise or refrain from exercising any rights against the Company and any other
Person.

     Section 11.15 . Third Party Beneficiaries. The holders of Senior Debt shall be third party
beneficiaries of the provisions of this Article 11, with the right and ability to enforce such
provisions for their own benefit.

     Section 11.16 . Liens. At no time will the obligations under the Notes be secured by a lien
or security interest in any property or assets. If, notwithstanding the foregoing, any such lien
or security interest at any time exists, such lien or security interest shall be subordinated to
the liens of the holders of Senior Debt, if any, in such property or assets and the holders of the
Senior Debt shall have the right, and is hereby authorized to, take such action as is required to
terminate and release such lien or security interest.

ARTICLE 12

Miscellaneous

     Section 12.01 . Trust Indenture Act of 1939. The Indenture shall incorporate and be governed
by the provisions of the Trust Indenture Act that are required to be part of and to govern
indentures qualified under the Trust Indenture Act.

     Section 12.02 . Noteholder Communications; Noteholder Actions. (a) The rights of Holders to
communicate with other Holders with respect to the Indenture or the Notes are as provided by the
Trust Indenture Act, and the Company and the Trustee shall comply with the requirements of Trust
Indenture Act Sections 312(a) and 312(b). Neither the Company nor the Trustee will be held
accountable

89

 

by reason of any disclosure of information as to names and addresses of Holders made
pursuant to the Trust Indenture Act.

     (b) (i) Any request, demand, authorization, direction, notice, consent to amendment,
supplement or waiver or other action provided by this Indenture to be given or taken by a Holder
(an “act”) may be evidenced by an instrument signed by the Holder delivered to the Trustee. The
fact and date of the execution of the instrument, or the authority of the person executing it, may
be proved in any manner that the Trustee deems sufficient.

     (ii) The Trustee may make reasonable rules for action by or at a meeting of Holders,
which will be binding on all the Holders.

     (c) Any act by the Holder of any Note binds that Holder and every subsequent Holder of a Note
that evidences the same debt as the Note of the acting Holder, even if no notation thereof appears
on the Note. Subject to paragraph (d), a Holder may revoke an act as to its Notes, but only if the
Trustee receives the notice of revocation before the date the amendment or waiver or other
consequence of the act becomes effective.

     (d) The Company may, but is not obligated to, fix a record date (which need not be within the
time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the purpose of
determining the Holders entitled to act with respect to any amendment or waiver or in any other
regard, except that during the continuance of an Event of Default, only the Trustee may set a
record date as to notices of default, any declaration or acceleration or any other remedies or
other consequences of the Event of Default. If a record date is fixed, those Persons that were
Holders at such record date and only those Persons will be entitled to act, or to revoke any
previous act, whether or not those Persons continue to be Holders after the record date. No act
will be valid or effective for more than 90 days after the record date.

     Section 12.03 . Notices. (a) Any notice or communication to the Company will be deemed given
if in writing (i) when delivered in person or (ii) five days after mailing when mailed by first
class mail, or (iii) when sent by facsimile transmission, with transmission confirmed. Notices or
