payment of principal, premium or Liquidated Damages, if any, or interest on such Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to
pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no
further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. 
 The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders
of each series of Notes and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date for the applicable series of
Notes and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes of such series and the Company shall otherwise
comply with TIA § 312(a).

 (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any
Note being redeemed in part; or 
 (C) to register the transfer of or to exchange a Note of any series between a record date
and the next succeeding interest payment date for the Note of such series. 
  

 28 








 (6) Prior to due presentment for the registration of a transfer of any Note, the Trustee,
any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of
the Trustee, any Agent or the Company shall be affected by notice to the contrary. 
 (7) The Trustee will authenticate Global
Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (8) All certifications,
certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 
 Section 2.07 Replacement Notes. 
 If any
mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will
authenticate a replacement Note of the same series if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the
Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder. 
 Section 2.08 Outstanding Notes. 
 The outstanding Notes of a series at any time are all the Notes of such series authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation, those reductions in the interest in a Global Note of such series effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set
forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds such Note. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date,
money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal
amount of Notes of the applicable series have concurred in any direction, waiver or consent, Notes of such series owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any Guarantor, will be considered as though not 
  

 29 








 outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such
direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes. 

Until certificates representing Notes of a series are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication
Order, will authenticate temporary Notes of such series. Temporary Notes of such series will be substantially in the form of certificated Notes of such series but may have variations that the Company considers appropriate for temporary Notes of such
series and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes of such series in exchange for temporary Notes of such series. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
 Section 2.11 Cancellation. 
 The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company
may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12 Defaulted
Interest. 
 If the Company defaults in a payment of interest on the Notes of any series, it will pay the defaulted interest in any lawful
manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will
notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note of the applicable series and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment
date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company,
the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 ARTICLE 3

 Section 3.01 Notices to Trustee. 
 If the Company elects to redeem Notes of any series pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 45 days but not more than 60 days before a redemption date, an
Officers’ Certificate setting forth: 
 (1) the clause of this Indenture pursuant to which the redemption shall occur;

  

 30 








 (2) the redemption date; 
 (3) the principal amount of Notes of such series to be redeemed; and 
 (4) the redemption price. 
 Section 3.02
Selection of Notes to Be Redeemed or Purchased. 
 If less than all of the Notes of any series are to be redeemed at any time, the
Trustee will select notes from such series for redemption on a pro rata basis unless otherwise required by law or applicable stock exchange requirements. 
 In the event of partial redemption or purchase by lot, the particular Notes of the applicable series to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the redemption or purchase date by the Trustee from the outstanding Notes of such series not previously called for redemption or purchase. 
 The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase as aforesaid and, in the case of any Note selected for partial redemption or purchase as aforesaid, the
principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding
amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to
portions of such Notes called for redemption or purchase. 
 Section 3.03 Notice of Redemption. 
 Subject to the provisions of Section 3.08 hereof, at least 30 days but not more than 60 days before a redemption date, the Company will mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in
connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof. 
 The
notice will identify the Notes to be redeemed and will state: 
 (1) the redemption date; 
 (2) the redemption price or, if such price cannot be determined at the time of the notice, the calculation method thereof; 
 (3) if any Note of any series is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the redemption date upon surrender of such Note, a new Note or Notes of such series in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
  

 31 








 (6) that, unless the Company defaults in making such redemption payment, interest on
Notes called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of the Notes and/or
Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (8) that no
representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes called for redemption. 
 At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days
prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

 Section 3.05 Deposit of Redemption or Purchase Price. 
 Except in connection with an Escrow Redemption as described in Section 3.08 hereof, one Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent
money sufficient to pay the redemption or purchase price of and accrued interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased on that date. Initially, unless the Trustee or the Paying Agent are directed otherwise in
writing by the Company, these funds will be deposited into the LaSalle Enhanced Liquidity Management (LELM) account until such funds are used for the redemption or purchase of the Notes or are returned to the Company. The Trustee or the Paying Agent
will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Liquidated Damages, if any, on, all
Notes to be redeemed or purchased. 
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption or
purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then
any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase
because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in such Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed or Purchased
in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication
Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 
  

 32 








 Section 3.07 Optional Redemption. 
 The Company may redeem all or a part of any series of Notes at a redemption price equal to the greater of (i) 100% of the principal amount of the
Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (excluding accrued and unpaid interest to the date of redemption) discounted to the date of
redemption on a semiannual basis (assuming 360-day years, each consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points for the 2016 Notes and 37.5 basis points for the 2036 Notes, in each case, together with accrued and unpaid
interest and Liquidated Damages, if any, thereon to the date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date. 
 Unless the Company defaults in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes or
portions thereof called for redemption. 
 Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof. 
 Section 3.08 Escrow Redemption. 
 If the proceeds from the sale of the Notes and the OCD Contribution have been paid into the Escrow Account (as defined in the Escrow Agreement) in
accordance with Section 3 of the Purchase Agreement and the Escrow Agent has, pursuant to Section 6(b) of the Escrow Agreement, released the Escrowed Property (including investment earnings) to the Trustee, the Trustee shall, on the
Business Day following the release of the Escrowed Property to the Trustee, redeem the Notes at a redemption price equal to 100% of the principal amount thereof, less the amount of any original issue discount, plus accrued and unpaid interest to,
but excluding, the date of redemption, plus, if the Notes are issued with original issue discount, the amount of the amortization of such original issue discount from the date of consummation of the first issuance of Notes under this Indenture to
the redemption date. 
 The Trustee shall pay to the Company any Escrowed Property remaining following the redemption of Notes pursuant to
this Section 3.08. Initially, unless the Trustee or the Paying Agent are directed otherwise in writing by the Company, Escrowed Property released to the Trustee will be deposited into the LaSalle Enhanced Liquidity Management (LELM) account
until such funds are used for the redemption or purchase of the Notes or are returned to the Company. 
 If the Company has provided the
Escrow Agent with a Plan Amendment Release Certificate (as defined in the Escrow Agreement) instructing the Escrow Agent to release the Escrow Property to the Trustee pursuant to Section 6(b) of the Escrow Agreement, the Company must
simultaneously provide a copy of such certificate to the Trustee, and the Trustee must promptly provide the Holders with a notice of redemption substantially in the form of the notice to be provided pursuant to Section 3.03 above.

 The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all

 If the Company or any of its Subsidiaries, directly or indirectly, creates, incurs, issues, assumes, guarantees or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to (collectively “incur”) any Indebtedness secured by a Lien (other than a Permitted Lien) upon any Principal Property or upon the Capital Stock of any
Subsidiary (in each case, now owned or hereafter acquired), the Company will secure the Notes on an equal and ratable basis with the Indebtedness so secured, unless the aggregate principal amount of all outstanding Indebtedness of the Company and
its Subsidiaries that is secured by Liens (other than Permitted Liens) on any Principal Property or upon the Capital Stock of any Subsidiary (in each case, now owned or hereafter acquired) plus the amount of all outstanding Attributable Debt
incurred pursuant to clause (1) of Section 4.09 would not exceed 10% of Consolidated Net Tangible Assets calculated as of the date of the creation or incurrence of the Lien.

accrued and unpaid interest and Liquidated Damages, if any, on the Notes of such series repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date

 (7)
that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or regulations conflict with
the provisions of Section 4.08 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.08 by virtue of such compliance.

 (c) Notwithstanding anything to the contrary in this Section 4.08, the
Company will not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set
forth in this Section 4.08 hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a

date of this Indenture, if that default: 
 (A) is caused by a failure to pay principal of, or interest or premium, if any,
on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 
 (B) results in the acceleration of such Indebtedness prior to its express maturity,

 Section 6.02 Acceleration. 
 In the case of an
Event of Default specified in clause (5) or (6) of Section 6.01 hereof, with respect to the Company, any Subsidiary of the Company that is a Significant Subsidiary or any group of Subsidiaries of the Company that, taken together,

 40 








 outstanding Notes of any series will become due and payable immediately without further action or notice. If any other
Event of Default with respect to outstanding Notes of any series occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes of such series may declare all the Notes of such series
to be due and payable immediately. 
 Upon any such declaration, the Notes shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes of a particular series by written notice to the Trustee may, on
behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Liquidated
Damages, if any, that has become due solely because of the acceleration) have been cured or waived. 
 Section 6.03 Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and
Liquidated Damages, if any, and interest on the Notes of any series affected thereby or to enforce the performance of any provision of such Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 
 Holders
of not less than a majority in aggregate principal amount of the then outstanding Notes of any series by notice to the Trustee may on behalf of the Holders of all such Notes waive an existing Default or Event of Default and its consequences
hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Liquidated Damages, if any, or interest on, the Notes of such series (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes of such series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon. 
 Section 6.05 Control by Majority. 
 Holders of a majority in aggregate principal amount of the then outstanding Notes of any series may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or
exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that
may involve the Trustee in personal liability. 
  

 41 








 Section 6.06 Limitation on Suits. 
 Except to enforce the right to receive payment of principal, premium, if any, or interest or Liquidated Damages, if any, when due, no Holder of a Note of
a particular series may pursue any remedy with respect to the Indenture or such series of Notes unless: 
 (1) such Holder
gives to the Trustee written notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate
principal amount of the then outstanding Notes of such series make a written request to the Trustee to pursue the remedy; 
 (3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes of such series do not give the Trustee a direction inconsistent with such request. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Liquidated Damages,
if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. 
 If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Liquidated Damages, if any, and interest remaining unpaid on, the Notes of any series and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 Section 6.09 Trustee May File Proofs of Claim. 
 The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to
collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in 
  

 42 








 any such judicial proceeding is hereby authorized by each Holder of a series of Notes to make such payments to the
Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities
and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of Notes of any series any plan of reorganization, arrangement, adjustment or composition affecting the Notes of such series or the rights of any Holder, or to authorize the Trustee
to vote in respect of the claim of any such Holder in any such proceeding. 
 Section 6.10 Priorities. 
 If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all
compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes of the applicable series for amounts due and unpaid on such Notes for principal, premium and Liquidated Damages, if any, and interest, ratably, without preference or priority of any kind, according to the
amounts due and payable on the Notes of such series for principal, premium and Liquidated Damages, if any and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 
 The
Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11 Undertaking
for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes of any series.

 ARTICLE 7 
 TRUSTEE 
 Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and

 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and

 (2) in the absence of bad
faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this

 (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may
require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may

 (f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture with respect to any series of Notes at the request or direction of any of the Holders of such series Notes unless such
Holders have offered to the Trustee reasonable indemnity or security against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction. 
 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 any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that
the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like
rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
 Section 7.04 Trustee’s Disclaimer. 
 The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be

 Section 7.05 Notice of Defaults. 
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium or Liquidated Damages, if any, or interest on, any Note, the Trustee may withhold the notice if and
so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
 Section 7.06 Reports by Trustee to Holders of the Notes. 
 (a) Within 60 days after each May 15 beginning with the
May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no
event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all
reports as required by TIA § 313(c). 
 (b) A copy of each report at the time of its mailing to the Holders of Notes will be
mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any
stock exchange. 
 Section 7.07 Compensation and Indemnity.

connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will
cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will
not be unreasonably withheld. 
 (c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the
satisfaction and discharge of this Indenture. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this
Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and
discharge of this Indenture. 
  

 46 








 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(7) or (8) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

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

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

  

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

 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes
of any series may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (e) If the Trustee, after
written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the
Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its
succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all 
  

 47 








 sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 
 Section 7.09 Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.

 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01
Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may at any time, at the option of its Board of Directors
evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes of any series upon compliance with the conditions set forth below in this Article 8.

 Section 8.02 Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes of any series (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter,
“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by such outstanding Notes (including the Note
Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their
other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will
survive until otherwise terminated or discharged hereunder: 
  

 48 








 (1) the rights of Holders of outstanding Notes to receive payments in respect of the
principal of, or interest or premium and Liquidated Damages, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 
 (2) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations
in connection therewith; and 
 (4) this Article 8. 
 Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors
will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.06, 4.08, 4.10, 4.11 hereof and clause (4) of Section 5.01 hereof with
respect to the outstanding Notes of any series on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and such Notes will thereafter be deemed not
“outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other
purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes of any series and Note Guarantees of such
series, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except
as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) and 6.01(4) hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant
Defeasance under either Section 8.02 or 8.03 hereof with respect to any series of Notes: 
 (1) the Company must
irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes of such series will occur, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the
opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, premium and Liquidated Damages, if any, and interest on, such outstanding Notes on the stated date for payment
thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes of such series are being defeased to such stated date for payment or to a particular redemption date;

from, or there has been published by, the Internal Revenue Service a ruling; or 
 (B) since the date of this Indenture, there
has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders of such outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had not occurred; 
 (3) in the case of an election
under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of such outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by
which the Company or any Guarantor is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach
or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of the Notes of such series over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited Money and Government
Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of
any Notes to be defeased will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent)
as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Liquidated Damages, if any, and interest, but such money need not be segregated from other funds except to the
extent required by law. 
  

 50 








 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of
the Holders of such Notes. 
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from
time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance
or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium or Liquidated Damages, if any, or interest on, any Note and remaining
unclaimed for two years after such principal, premium or Liquidated Damages, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the
Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will
thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be
repaid to the Company. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture with respect to such Notes and the Note Guarantees affected
thereby will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium or Liquidated Damages, if any, or interest on, any Note following the reinstatement of its obligations, the Company will be
subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 
 Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes of any
series or the Note Guarantees with respect to such series without the consent of any Holder of any Note of such series: 
 (1)
to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of
certificated Notes; 
 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the
Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor pursuant to Article 5 or Article 10 hereof; 
 (4) to make any change that would provide any additional rights or benefits to the Holders of the Notes of a particular series or that does not adversely affect the legal rights hereunder of any such Holder; 
 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

(6) to conform the text of this Indenture, the Escrow Agreement or the Notes to any provision of the “Description of Notes”
section of the Company’s Offering Memorandum dated October 31, 2006, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a
provision of this Indenture, the Note Guarantees or the Notes; 
 (7) to provide for the issuance of Additional Notes in
accordance with the limitations set forth in this Indenture as of the date hereof; or 
 (8) to allow any Guarantor to execute
a supplemental indenture and/or a Note Guarantee with respect to the Notes of a particular series. 
 Upon the request of the Company
accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the
Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the
Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders of Notes. 
 Except as provided below in this
Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Section 4.08 hereof) and the Notes and the Note Guarantees of each series affected thereby with the consent of the Holders of
at least a majority in aggregate principal amount of the then outstanding Notes of each such series (including, without 
  

 52 








 limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, such Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of,
premium or Liquidated Damages, if any, or interest on, the Notes of a series, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees of
a series may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes of such series (including, without limitation, Additional Notes, if any) voting as a single class (including, without
limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, such Notes). Section 2.08 hereof shall determine which Notes are to be considered “outstanding” for purposes of this
Section 9.02. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any
such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes of the applicable series as aforesaid, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights,
duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture. 
 It is not necessary for the consent of the Holders of Notes of the applicable series under this Section 9.02 to approve the particular form of any
proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 After an amendment,
supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes of each series affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail
such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal
amount of the Notes of each series then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or such Notes or Note Guarantees with respect to such series. However,
without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes of any series whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the
redemption of the Notes (except as provided above with respect to Section 4.08 hereof); 
 (3) reduce the rate of or
change the time for payment of interest, including default interest, on any Note; 
 (4) waive a Default or Event of Default
in the payment of principal of, or premium or Liquidated Damages, if any, or interest on, the Notes of any series (except a rescission of acceleration of the Notes of such series by the Holders of at least a majority in aggregate principal amount of
the then outstanding Notes of such series and a waiver of the payment default that resulted from such acceleration); 
  

 53 








 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, or interest or premium or Liquidated Damages, if any, on, the Notes; 
 (7) waive a redemption
payment with respect to any Note (other than a payment required by Section 4.08 hereof); 
 (8) release any Guarantor
from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 
 (9) make any change in the preceding amendment and waiver provisions. 
 Section 9.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes will be set forth in a amended or supplemental indenture that complies with the TIA as
then in effect. 
 Section 9.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective with respect to any Note of any series, a consent to it by a Holder of a Note of that series is a continuing consent by the Holder of a Note and every
subsequent Holder of such Note or portion of such Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any such Note. However, any such Holder of a Note or subsequent Holder of a Note
may revoke the consent as to such Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for
the affected Note may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate a new Note of that same series that reflects the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 

Section 9.06 Trustee to Sign Amendments, etc. 
 The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not
sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully
protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by
this Indenture.

 ARTICLE 10 
 NOTE GUARANTEES 
  

	Section	10.01 Guarantee. 

 (a) Subject to this Article 10,
each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability
of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 
 (1) the principal of, premium
and Liquidated Damages, if any, and interest on, the Notes of any series will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes of
such series, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of
payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery
of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be
discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder or the Trustee
is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or
such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor
agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such
obligations (whether or not due and payable) will 
  

 55 








 forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 
 Section 10.02 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer
Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be
limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to
receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a
fraudulent transfer or conveyance. 
 Section 10.03 Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially
in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

 Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
 If an Officer whose signature is on this Indenture
or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this
Indenture on behalf of the Guarantors. 
 In the event that the Company or any of its Subsidiaries creates or acquires any Domestic
Subsidiary after the date of this Indenture, if required by Section 4.10 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.10 hereof and this Article 10, to the extent applicable.

 Section 10.04 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless immediately after giving effect to such transaction, no Default or Event of Default
exists. 
 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual 
  


 56 








 performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor
Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the
Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note
Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 
 Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the
Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or
another Guarantor. 
 Section 10.05 Releases. 
 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of
any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger,
consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and
relieved of any obligations under its Note Guarantee; provided that the net proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture. Upon delivery by the Company to the Trustee of
an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, the Trustee will execute any documents reasonably required in
order to evidence the release of any Guarantor from its obligations under its Note Guarantee. 
 (b) Each Guarantor will be released and
relieved of any obligations under its Note Guarantee: 
 (1) upon the release, discharge or termination of the
Subsidiary’s Guarantee of the Credit Agreement, except a discharge, release or termination by or as a result of payment under such Guarantee; or 
 (2) upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof. 
 Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of
principal of and interest and premium and Liquidated Damages, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10. 
  

 57 








 ARTICLE 11 
 SATISFACTION AND DISCHARGE 
 Section 11.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect with respect to the 2016 Notes or the 2036 Notes, as the case may be, issued
hereunder, when: 
 (1) either: 
 (a) all Notes of the applicable series that have been authenticated, except lost, stolen or destroyed Notes of such series that have been replaced or paid and Notes of such series for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 
 (b) all Notes of the applicable series that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year
and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof,
in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes of such series not delivered to the Trustee for cancellation for principal, premium and
Liquidated Damages, if any, and accrued interest to the date of maturity or redemption; 
 (2) no Default or Event of Default
has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a
default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture with respect to the applicable series of Notes; and 
 (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment
of the Notes of the applicable series at maturity or on the redemption date, as the case may be. 
 In addition, the Company must deliver an Officers’
Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof
will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 Section 11.02 Application of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the 
  

 58 








 Notes of the applicable series and this Indenture, to the payment, either directly or through any Paying Agent (including
the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Liquidated Damages, if any) and interest for whose payment such money has been deposited with the Trustee;
but such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to
apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes of the applicable series shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided
that if the Company has made any payment of principal of, premium or Liquidated Damages, if any, or interest on, any such Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such
Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Owens Corning, a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at             % per annum from             ,
20     until maturity and shall pay the Liquidated Damages, if any, payable pursuant to Section 8 of the Notes Registration Rights Agreement referred to below. The Company will pay interest and Liquidated Damages, if
any, semiannually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be June 1, 2007. The
Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect to
the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if any, (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) and Liquidated Damages, if any, to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and Liquidated Damages, if any, and interest at the office or agency of the Company maintained for such purpose within or
without the City and State of New York, or, at the option of the Company, payment of interest and Liquidated Damages, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that
payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Liquidated Damages, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire
transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND REGISTRAR. Initially, LaSalle Bank
National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

  

 A1-2 








 (4) INDENTURE. The Company issued the Notes under an
Indenture dated as of October 31, 2006 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 
 (5) OPTIONAL REDEMPTION. 
 (a) The Company may redeem all or a part of any series of Notes at a redemption price equal to the greater of (i) 100% of the
principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (excluding accrued and unpaid interest to the date of redemption)
discounted to the date of redemption on a semiannual basis (assuming 360-day years, each consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points for the 2016 Notes and 37.5 basis points for the 2036 Notes, in each case,
together with accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

 (b) Unless the Company defaults in payment of the redemption price, on and after the date of redemption, interest will
cease to accrue on the Notes or portions thereof called for redemption. 
 (c) Any redemption pursuant to Section 3.07 of
the Indenture shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture 
 (6)
ESCROW REDEMPTION.  
 If the proceeds from the sale of the Notes and the OCD
Contribution have been paid into the Escrow Account (as defined in the Escrow Agreement) in accordance with Section 3 of the Purchase Agreement and the Escrow Agent has, pursuant to Section 6(b) of the Escrow Agreement, released the
Escrowed Property (including investment earnings) to the Trustee, the Trustee shall, on the Business Day following the release of the Escrowed Property to the Trustee, redeem the Notes at a redemption price equal to 100% of the principal amount
thereof, less the amount of any original issue discount, plus accrued and unpaid interest to, but excluding, the date of redemption, plus, if the Notes are issued with original issue discount, the amount of the amortization of such original issue
discount from the date of consummation of the first issuance of Notes under this Indenture to the redemption date. 
 The
Trustee shall pay to the Company any Escrowed Property remaining following the redemption of Notes pursuant to Section 3.08 of the Indenture. Initially, unless the Trustee or the Paying Agent are directed otherwise in writing by the Company,
Escrowed Property released to the Trustee will be deposited into the LaSalle Enhanced Liquidity Management (LELM) account until such funds are is used for the redemption or purchase of the Notes or are returned to the Company. 
  

 A1-3 








 If the Company has provided the Escrow Agent with a Plan Amendment Release Certificate

and the Trustee must promptly provide the Holders with a notice of redemption substantially in the form of the notice to be provided pursuant to Section 3.03 of the Indenture. 
 (7) REPURCHASE AT THE OPTION OF HOLDER.

 (a) If there is a Change of Control Repurchase Event, the Company will be required to make an offer (a “Change of
Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control
Payment”). Within 10 days following any Change of Control Repurchase Event, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. 
 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The
Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a

transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

 A1-4 








 provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes

extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Note Guarantees, the Escrow Agreement or the Notes; to provide for the issuance of Additional Notes in
accordance with the limitations set forth in the Indenture or to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Note Guarantee with respect to the Notes.

for 30 days in the payment when due of interest on, or Liquidated Damages, if any, with respect to the Notes; (ii) default in the payment when due of the principal of, or premium, if any, on, the Notes when the same becomes due and payable at

aggregate principal amount of the Notes including Additional Notes, if any, then outstanding voting as a single class to comply with any of the other agreements in the Indenture or the Notes; (iv) default under certain other agreements relating
to Indebtedness of the Company which default results in the acceleration of such Indebtedness prior to its express maturity; (v) certain events of bankruptcy or insolvency with respect to the Company or any of its Subsidiaries that is a
Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary; and (vi) except as permitted by the Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or
invalid or ceases for any reason to be in full force and effect or any Guarantor or any Person acting on its behalf denies or disaffirms its obligations under such Guarantor’s Note Guarantee. If any Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of principal or interest or premium or Liquidated Damages, if any) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest or premium or Liquidated Damages, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

 EXHIBIT E 
 [FORM OF SUPPLEMENTAL INDENTURE 
 TO BE DELIVERED BY SUBSEQUENT GUARANTORS] 
 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
                    , 200  , among
                            (the “Guaranteeing Subsidiary”), a subsidiary of Owens
Corning (or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and LaSalle Bank National Association, as trustee under the Indenture
referred to below (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of October 31,
2006 providing for the issuance of 6.50% Senior Notes due 2016 and the 7.00% Senior Notes due 2036 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all
of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for
the equal and ratable benefit of the Holders of the Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized
terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 2. AGREEMENT
TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to
Article 10 thereof. 
 4. NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture
or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.
