All Notes shall be dated the date of their authentication. Upon initial issuance, the Notes shall be authenticated by the Indenture Trustee pursuant to, and upon the Indenture Trustee’s receipt of, an Issuer Order.

(b) The Indenture Trustee may appoint one or more agents (each an “Authenticating Agent”) with power to act on its behalf and subject to its direction in the authentication of Notes in connection with transfers and exchanges under Sections 2.04 and 2.05, as fully to all intents and purposes as though each such Authenticating Agent had been expressly authorized by those Sections to authenticate the Notes.

(c) The First Issuance Notes shall be issued on the Issue Date, and the Second Issuance Notes shall be issued on the Second Issue Date.

Any corporation, bank, trust company or association into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation, bank, trust company or association resulting from any merger, consolidation or conversion to which any Authenticating Agent shall be a party, or any corporation, bank, trust company or association succeeding to all or substantially all of the corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, without the execution or filing of any further act on the part of the parties hereto or such Authenticating Agent or such successor corporation, bank, trust company or association.

25

(b) No transfer, sale, pledge or other disposition of any Note or interest therein shall be made unless that transfer, sale, pledge or other disposition is exempt from the registration and/or qualification requirements of the Securities Act, regulations promulgated thereunder and any applicable state securities laws, or is otherwise made in accordance with the Securities Act, regulations promulgated thereunder and such state securities laws. None of the Issuer, the Indenture Trustee or the Note Registrar is obligated to register or qualify any Notes under the Securities Act, regulations promulgated thereunder or any other securities law or to take any action not otherwise required under this Indenture to permit the transfer of any Note or interest therein without registration or qualification. Any Holder desiring to effect a transfer of Notes or interests therein shall, and is hereby deemed to have agreed to, indemnify and hold harmless the Issuer, the Indenture Trustee and the Note Registrar against costs, damages, or any other liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

(c) The Note Registrar shall refuse to register any requested transfer unless it receives (and upon receipt, may conclusively rely upon) a certification from the transferring Holder in substantially the form of Exhibit B-1 hereto, and a representation letter from the transferee, in substantially the form of Exhibit B-2 hereto, and shall have no duty to determine whether such transfer is so exempt or complies with such federal and state laws. The Note Registrar may conclusively rely on the same; provided, however , that the Note Registrar or the Indenture Trustee, as the case may be, shall be under a duty to require delivery and to examine to determine whether it substantially appears on its face to conform with such exhibit as attached to this Indenture, the certificate in substantially the form of Exhibit B-1 or the representation letter in substantially the form of Exhibit B-2 specifically required by the express terms of this Section 2.04 to be delivered to the Note Registrar or the Indenture Trustee as a requirement of the registration of a transfer of a Note.

(d) Any purported transfer of a Note to a Person that does not comply with the requirements set forth above will be null and void ab initio and the transferor (or the last preceding Holder of such Note (or interest therein)) that was not so disqualified shall be restored to all rights as a Holder thereof retroactively to the date of transfer of such Note by such disqualified transferee. None of the Indenture Trustee, the Note Registrar or any other Person shall be obligated to register or otherwise recognize such purported transfer of a Note. Nothing herein shall impose an affirmative duty on the Note Registrar or Indenture Trustee to investigate or make other inquiries as to whether a purported transferee has complied with the requirements set forth above.

(e) If a Person is acquiring any Note or interest therein as a fiduciary or agent for one or more accounts, such Person shall be required to deliver to the Note Registrar a certification to the effect that it has (i) sole investment discretion with respect to each such account and (ii) full power to make the foregoing acknowledgments, representations, warranties, certifications and agreements with respect to each such account as set forth in this Section 2.04 (and upon receipt, the Note Registrar may conclusively rely upon such certification) and shall have no duty to determine whether the Person acquiring such Note or interest therein is such a fiduciary or agent, or has such discretion or power, as the case may be.

26

(f) Subject to the preceding provisions of this Section 2.04, upon surrender for registration of transfer of any Note at the offices of the Note Registrar maintained for such purpose, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver, in the name of the designated transferee or transferees (and, to the extent that only a portion of the transferring Holder’s Note Balance is being transferred, to the transferring Holder), one or more new Notes, of a like Note Balance.

(g) At the option of any Holder, its Notes may be exchanged for other Notes of a like Note Balance upon surrender of the Notes to be exchanged at the offices of the Note Registrar maintained for such purpose. Whenever any Notes are so surrendered for exchange, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver the Notes which the Holder making the exchange is entitled to receive.

(h) Every Note presented or surrendered for transfer or exchange shall (if so required by the Note Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Note Registrar duly executed by, the Holder thereof or its attorney duly authorized in writing. The Note Registrar may require any Holder, among other things, to furnish any appropriate endorsements and transfer documents, and to have signatures guaranteed by an “eligible guarantor institution” that is a member or participant in a recognized “signature guarantee program” (e.g., the securities Transfer Agents Medallion Program, the Stock Exchange Medallion Program or the New York Stock Exchange, Inc. Medallion signature Program).

(i) No service charge shall be imposed for any transfer or exchange of Notes, but the Indenture Trustee or the Note Registrar may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Notes.

(j) All Notes surrendered for transfer and exchange shall be physically canceled by the Note Registrar, and the Note Registrar shall dispose of such canceled Notes in accordance with its standard procedures.

(k) The Note Registrar shall provide to the Issuer or the Indenture Trustee, upon reasonable prior written request, and at the expense of the Issuer, an updated copy of the Note Register. The Issuer and the Indenture Trustee shall have the right to obtain a copy thereof within a reasonable amount of time after receipt of notice by the Note Registrar, and to rely conclusively upon a certificate of the Note Registrar as to the information set forth in the Note Register.

(l) Neither the Note Registrar nor the Indenture Trustee shall be under any duty to monitor or determine compliance with any federal, state or other securities or tax laws that may be applicable.

27

(m) The Note Registrar shall be entitled to all of the protections, privileges, limitations on liability, rights of reimbursement and indemnities that the Indenture Trustee is entitled to hereunder as fully as if it were the Indenture Trustee.

(n) The Indenture Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any 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.

(o) Each Note issued hereunder shall, upon issuance, bear the legend set forth in this clause (o), and such legend shall not be removed except as provided in clause (b) above. Each Note that bears or is required to bear the legend shall be subject to the restrictions on transfer set forth in the legend, and the Holder of each such Note, by such Holder’s acceptance thereof, shall be deemed to have agreed to be bound by all such restrictions on transfer. Any certificate evidencing such Note shall bear a legend in substantially the following form:

SECTION 2.05. Mutilated, Destroyed, Lost or Stolen Notes .

If any mutilated Note is surrendered to the Note Registrar, the Issuer shall execute and the Indenture Trustee, upon receipt of an Issuer Order, shall authenticate and deliver, in exchange therefor, a new Note of the same tenor and denomination, registered in the same manner, dated the date of its authentication and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Issuer, the Indenture Trustee and the Note Registrar (i) evidence to their satisfaction of the destruction (including mutilation tantamount to destruction), loss or theft of any Note and the ownership thereof and (ii) such security or indemnity as may be required by them to hold each of them, and any agent of any of them harmless, then, in the absence of written notice received by the Issuer or a Trust Officer that such Note has been acquired by a Protected Purchaser, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of the same tenor and denomination registered in the same manner, dated the date of its authentication and bearing a number not contemporaneously outstanding.

29

Upon the issuance of any new Note under this Section 2.05, the Indenture Trustee and the Note Registrar may require the payment by the Holder of an amount sufficient to pay or discharge any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses, but no service charge.

Every new Note issued pursuant to this Section 2.05 in lieu of any destroyed, mutilated, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer, whether or not the destroyed, mutilated, lost or stolen Note shall be at any time enforceable by any Person, and such new Note shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 2.05 are exclusive and shall preclude (to the extent permitted by applicable law) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.06. Holder Lists .

The Note Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders, which list, upon request, will be made available to the Indenture Trustee insofar as the Indenture Trustee is no longer the Note Registrar. Upon written request of any Holder made for purposes of communicating with other Holders with respect to their rights under this Indenture (which purpose the Note Registrar shall have no duty to determine or inquire about), the Note Registrar shall within five (5) Business Days after its receipt of such written request furnish such Holder with a list of the other Holders of record identified in the Note Register at the time of the request. Every Holder, by receiving such access, agrees with the Note Registrar that the Note Registrar will not have any liability or be held accountable in any way by reason of the disclosure of any information as to the names and addresses of any Holder regardless of the source from which such information was derived.

SECTION 2.07. Persons Deemed Owners .

The Issuer, the Indenture Trustee, the Note Registrar and any agents of any of them, may treat the Person in whose name a Note is registered as the owner of such Note on the applicable Record Date for the purpose of receiving payments of principal, interest and other amounts in respect of such Note and on any other date for all other purposes whatsoever, whether or not such Note shall be overdue, and none of the Issuer, the Indenture Trustee, the Note Registrar or any agents of any of them, shall be affected by notice to the contrary.

SECTION 2.08. Payments on the Notes .

(a) With respect to each Payment Date, any interest, principal and other amounts payable on the Notes shall be paid to the Person that is the registered Holder thereof at the close of business on the related Record Date. Payments of interest, principal and other amounts on the Notes shall be made by wire transfer to such account as such Holder shall designate, by written instruction received by the Indenture Trustee not later than five Business Days prior to the Record Date related to the applicable Payment Date. Notwithstanding the foregoing, interest shall be considered paid on the date due upon the increase of the Note Balance in an amount equal to the applicable PIK Payment in accordance with Section 2.03(b).

30

(b) If a Note is issued in exchange for any other Note during the period commencing at the close of business at the office of the Note Registrar where such exchange occurs on any Record Date and ending before the opening of business at such office of the Note Registrar on the related Payment Date, no interest, principal or other amounts will be payable on such Payment Date in respect of such new Note, but will be payable on such Payment Date only in respect of the prior Note to the Person that is the registered Holder thereof at the close of business on the related Record Date.

(c) The Issuer shall pay to the Indenture Trustee sufficient funds in an amount to pay in full all amounts of interest, principal, and if any, premium due on any Payment Date, redemption date, the Final Maturity Date, or otherwise prior to 11:00 a.m. Eastern time on such date.

SECTION 2.09. Compliance with Withholding and Other Requirements .

The Indenture Trustee shall comply with all backup withholding tax and information reporting requirements that it is required to comply with under applicable law (including the Code and the Treasury regulations issued thereunder) in respect of any payment on, or in respect of, the Notes.

By acceptance of any Note issued hereunder, each Holder is deemed to agree to provide to the Issuer or Indenture Trustee any certification that may be required under applicable law and to update or replace such form or certification in accordance with its terms or its subsequent amendments to the extent necessary. Failure of a Holder to provide the Indenture Trustee and the Issuer with required tax certificates may result in amounts of tax being withheld from the payment to such Holder.

In order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering and Section 326 of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (collectively, “Applicable Regulations”), the Indenture Trustee, like all financial institutions, is required to obtain, verify and record certain information relating to individuals and legal entities which maintain a business relationship or opens an account with the Indenture Trustee. Accordingly, each of the parties hereto and each Holder agrees to provide the Indenture Trustee, upon its request from time to time, such identifying information and documentation as may be necessary in order to enable the Indenture Trustee to comply with such Applicable Regulations. It is expressly agreed that the Indenture

31

Trustee shall have no duty to perform any services hereunder for, on behalf of or for the benefit of, any Person not having furnished such information as the Indenture, in its sole discretion, determines to be necessary to comply with the Applicable Regulations.

SECTION 2.10. Cancellation .

All such Notes and all Notes surrendered for transfer and exchange in accordance with the terms hereof shall be canceled and disposed of by the Note Registrar in accordance with its customary procedures.

SECTION 2.11. Lien of the Indenture .

This Indenture shall evidence a continuing Lien on and security interest in the Trust Estate in favor of the Indenture Trustee for the benefit of the Holders to secure the full payment of the principal, interest and other amounts on all the Notes, which shall in all respects be equally and ratably secured hereby without preference, priority or distinction on account of the actual time or times of the authentication and delivery of the Notes.

SECTION 2.12. Uniform Commercial Code Matters .

(a) The Issuer shall take all actions, including the authorization and filing of all financing statements and amendments thereto, as are necessary to perfect and maintain the perfection and priority under the laws of all relevant jurisdictions of the security interest Granted by the Issuer to the Indenture Trustee hereunder. The Issuer hereby irrevocably authorizes the filing of financing statements (and amendments of financing statements and continuation statements) that name the Issuer as debtor and the Indenture Trustee as secured party and that cover all personal property of the Issuer. The Issuer also hereby ratifies its authorization of the filing of any such financing statements (or amendments of financing statements or continuation statements) that were filed prior to the execution hereof. The Indenture Trustee shall have no obligation to file or monitor any financing statements (or amendments of financing statements or continuation statements) or be responsible for maintaining the security interests purported to be created as described herein (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder) and such responsibility shall be solely that of the Issuer.

(b) The Indenture Trustee acknowledges and agrees that it holds each item of Collateral within its possession or control on behalf of and for the benefit of the Secured Parties. Notwithstanding any other provision of this Indenture, the Indenture Trustee shall not hold any item of Collateral through an agent or nominee except as expressly permitted by the Transaction Documents to which it is a party.

32

(c) The Indenture Trustee shall not be responsible for and makes no representation as to the existence, genuineness, value or protection of any Collateral, or for the creation, perfection, priority, sufficiency or protection of any liens securing the Notes.

SECTION 2.13. CUSIP Numbers .

The Issuer in issuing the Notes shall use CUSIP numbers, and may, and at the reasonable request of a Holder shall, use ISINs and “Common Code” numbers (if then generally in use) and the Indenture Trustee shall use CUSIP numbers, and, if applicable, ISINs and “Common Code” numbers in notices (including notices of redemption) as a convenience to Holders; provided, however , that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Notes or as contained in any notice that reliance may be placed only on the other identification numbers printed on the Notes and that any such notice shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Indenture Trustee in writing of any change in the CUSIP numbers, ISINs and “Common Code” numbers, on which notice the Indenture Trustee may conclusively rely without investigation.

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

The term “Bankruptcy Law” means Title 11, United States Code, or any similar U.S. federal or state law for the relief of debtors (or their foreign equivalents). The term “custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

SECTION 5.02. Acceleration . If an Event of Default (other than an Event of Default specified in Section 5.01(f) or (g) with respect to the Issuer) occurs and is continuing, the Indenture Trustee or the Required Holders by notice to the Issuer may, and if such notice is given by the Required Holders such notice shall be given to the Issuer and the Indenture Trustee, declare that the principal of, and the premium, if any, and accrued but unpaid interest on, all Notes is due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 5.01(f) or (g) with respect to the Issuer occurs, the principal of, and the premium, if any, and accrued but unpaid interest on, all the Notes shall ipso facto become and be immediately due and payable, without any declaration or other act on the part of the Indenture Trustee or any Holders. The Required Holders by written notice to the Indenture Trustee may rescind an acceleration and its consequences if such Required Holders determine that the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.

52

SECTION 5.03. Other Remedies . If an Event of Default occurs and is continuing, the Indenture Trustee, after notice to the Holders and receipt of specific written direction from the Required Holders as to how to proceed, may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Indenture 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 Indenture Trustee or any Holder 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. No remedy is exclusive of any other remedy. To the extent required by law, all available remedies are cumulative.

Following an Event of Default, the Required Holders may instruct the Indenture Trustee to deliver the “Notice of Exclusive Control” (or similar defined term) under and as defined in any Account Control Agreement.

SECTION 5.04. Waiver of Past Defaults . Provided the Notes are not then due and payable by reason of a declaration of acceleration, the Required Holders by written notice to the Indenture Trustee may waive an existing Default or an Event of Default and its consequences except (a) a Default or an Event of Default in the payment of the principal of or interest on a Note, (b) a Default or an Event of Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a Default or an Event of Default in respect of a provision that under Section 8.02 cannot be amended without the consent of each Holder affected. When a Default or an Event of Default is waived, it is deemed cured and the Issuer, the Indenture Trustee and the Holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or an Event of Default or impair any consequent right. Any past Default or an Event of Default or compliance with any provisions may be waived with the consent of the Required Holders.

SECTION 5.05. Control by Majority . The Required Holders may direct the time, method and place of conducting any proceeding for any remedy available to the Indenture Trustee or of exercising any trust or power conferred on the Indenture Trustee. However, the Indenture Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Indenture Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Indenture Trustee in personal liability. Prior to taking any action under this Indenture, the Indenture Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. The Holders understand and agree that in fulfilling its role as Indenture Trustee under an Account Control Agreement, if any, the Indenture Trustee shall act solely in accordance with the written direction of the Required Holders.

53

SECTION 5.06. Limitation on Suits . (a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

(i) the Holder gives the Indenture Trustee written notice stating that an Event of Default is continuing;

(ii) the Required Holders make a written request to the Indenture Trustee to pursue the remedy;

(iii) such Holder or Holders offer to the Indenture Trustee security or indemnity satisfactory to it against any loss, liability or expense; and

(iv) the Indenture Trustee does not comply with the request within 30 days after receipt of the request and the offer of security or indemnity.

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

SECTION 5.07. Rights of the Holders to Receive Payment . Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Notes held by such Holder, on or after the respective due dates expressed or provided for in this Indenture or in the Notes, 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 5.08. Collection Suit by Indenture Trustee . If an Event of Default specified in Section 5.01(a) occurs and is continuing, the Indenture Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 6.05.

SECTION 5.09. Indenture Trustee May File Proofs of Claim . The Indenture Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Indenture Trustee (including counsel, accountants, experts or such other professionals as the Indenture Trustee deems necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Issuer, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions and be a member of a creditors’ or other similar committee, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Indenture Trustee and, in the event that the Indenture Trustee shall consent to the making of such payments directly to the Holders, to pay to the Indenture Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee, its agents and its counsel, and any other amounts due the Indenture Trustee under Section 6.05.

54

SECTION 5.10. Priorities . If the Indenture Trustee collects any money or property pursuant to this Article 5, it shall pay out such money or property in the following order:

FIRST: to the Indenture Trustee for amounts due under Section 6.05;

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

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

FOURTH: to the Issuer.

The Indenture Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 5.10. At least 15 days before such record date, the Indenture Trustee shall mail to each Holder and the Issuer a notice that states the record date, the payment date and amount to be paid.

SECTION 5.11. Waiver of Stay or Extension Laws . The Issuer shall 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 wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

56

SECTION 6.02. Rights of Indenture Trustee . (a) The Indenture Trustee may conclusively rely and shall be protected in acting or refraining from acting on any document believed by it to be genuine and to have been signed or presented by the proper person. The Indenture Trustee need not investigate any fact or matter stated in the document. Without limiting the generality of the foregoing, the following provisions of this Section 6.02 shall apply notwithstanding any provision of this Agreement or any other Transaction Document to the contrary.

(b) Before the Indenture Trustee acts or refrains from acting, it may require, at the expense of the Issuer, an Officer’s Certificate or an Opinion of Counsel or both and may conclusively rely on the same. The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on any Officer’s Certificate or Opinion of Counsel.

(d) The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however , that the Indenture Trustee’s conduct does not constitute willful misconduct or gross negligence.

(e) The Indenture Trustee may, at the expense of Issuer, consult with counsel of its own selection and the advice or opinion of counsel with respect to legal matters relating to this Indenture, the Notes, or any other Transaction Documents or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel or Opinion of Counsel.

(f) The Indenture Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document, but the Indenture Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Indenture Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney, at the expense of the Issuer and shall incur no liability of any kind by reason of such inquiry or investigation.

(g) The Indenture Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or any other Transaction Document at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Indenture Trustee security or indemnity satisfactory to the Indenture Trustee in its sole discretion against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

The failure of such language to be so included shall excuse the Indenture Trustee from being required to join in the execution of such documents, without regard to any consequences that may result therefrom.

(m) Any request or direction of the Issuer mentioned herein shall be sufficiently evidenced by an Issuer Order.

(n) As a condition to the taking or omitting of any action by it hereunder, the Indenture Trustee may at the expense of the Issuer consult with counsel and the advice of such counsel or any opinion of counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in reliance thereon.

(o) Whenever this Indenture or any other Transaction Document provides that an action may be taken or not taken at the option, election or in the discretion of the Indenture Trustee, the Indenture Trustee shall have no obligation or duty to exercise such option, make such election, or exercise such discretion except upon the reasonable written instructions of the Issuer or the Required Holders. The Indenture Trustee shall have no liability to any party for carrying out any such direction.

(p) The permissive rights of the Indenture Trustee to take or refrain from taking any action enumerated in this Indenture or any other Transaction Document shall not be treated as a duty.

59

to the provisions of this Indenture or any other Transaction Document, unless such Holders shall have offered to the Indenture Trustee reasonable security or indemnity against the costs, expenses and liabilities that may be incurred therein or thereby.

(w) If the Indenture Trustee believes inconsistent alternative courses of action are permitted or required by the terms of this Indenture or any of the Transaction Documents, to which the Indenture Trustee is a party, believes that the terms of the Indenture or any of the Transaction Documents, to which the Indenture Trustee is a party are ambiguous, or is unsure as to the application, intent, interpretation or meaning of any provision of this Indenture or any other Transaction Document to which it is a party, the Indenture Trustee after reasonable diligence and consultation with counsel, shall take such action which, in its view, is in the best interest of the Holders and consistent with this Indenture unless it otherwise receives written direction from the Required Holders prior to such action, and notwithstanding any provision of this Indenture or any Transaction Document, or otherwise, the Indenture Trustee shall have no liability to any Person for any such action or following such direction.

(x) The receipt by the Indenture Trustee of any reports, information or other documents that are provided to the Indenture Trustee for purposes of enabling the sending party to comply with its document delivery requirements hereunder shall not constitute constructive or actual notice of any information contained therein or determinable from any information contained therein, including any other Person’s compliance with any of its covenants, representations or warranties hereunder, unless otherwise specifically set forth in this Indenture.

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

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

(aa) The Indenture Trustee may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

SECTION 6.03. Individual Rights of Indenture Trustee . The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Indenture Trustee. The Indenture Trustee and its affiliates have engaged, currently are engaged and may in the future engage in financial or other transactions with the Issuer and its affiliates in the ordinary course of their respective businesses. Any Note Registrar may do the same with like rights. However, the Indenture Trustee must comply with Section 6.09.

60

SECTION 6.04. Indenture Trustee’s Disclaimer . The Indenture Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes, any Security Documents or any other Transaction Documents, it shall not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Indenture Trustee’s certificate of authentication.

SECTION 6.05. Compensation and Indemnity . The Issuer shall pay to the Indenture Trustee from time to time compensation for its services as set forth in a separate instrument. The Indenture Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Indenture Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Indenture Trustee’s agents, counsel, accountants and experts. The Issuer shall indemnify, protect, defend and hold harmless the Indenture Trustee, and each of its officers, directors, shareholders, employees and agents (collectively, the “Indemnified Persons”) against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by such Person or in connection with the acceptance or administration of this trust and the performance of its duties hereunder and under any other Transaction Document, including the costs and expenses of enforcing this Indenture or any other Transaction Document against the Issuer (including this Section 6.05) and defending itself against or investigating any claim (whether asserted by the Issuer, any Holder or any other Person). The obligation to pay such amounts shall survive the payment in full or defeasance of the Notes or the removal or resignation of the Indenture Trustee. The Indenture Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof (such notice, the “Claim Notice”); provided , however , that any failure so to notify the Issuer shall not relieve the Issuer of its indemnity obligations hereunder. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, gross negligence or bad faith.

To secure the Issuer’s payment obligations in this Section 6.05, the Indenture Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Indenture Trustee other than money or property held in trust to pay principal of and interest on particular Notes.

The Issuer’s payment obligations pursuant to this Section 6.05 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Indenture Trustee. Without prejudice to any other rights available to the Indenture Trustee under applicable law, when the Indenture Trustee incurs expenses after the occurrence of a Default specified in Section 5.01(f) or Section 5.01(g) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

No provision of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction.

61

SECTION 6.06. Replacement of Indenture Trustee . (a) The Indenture Trustee may resign at any time by so notifying the Issuer. The Required Holders may remove the Indenture Trustee by so notifying the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuer shall remove the Indenture Trustee if:

(i) the Indenture Trustee fails to comply with Section 6.08;

In the event the Indenture Trustee is required to disclose any such information received hereunder in order to comply with any Requirements of Law, it may disclose such information only to the extent necessary for such compliance; provided, however, that it shall give the Issuer or any Holder (or any holder of a beneficial interest in the Notes), as applicable, reasonable advance written notice of any court proceeding in which such disclosure may be required pursuant to a court order so as to afford the Issuer or any Holder (or any holder of a beneficial interest in the Notes), as applicable, full and fair opportunity to oppose the issuance of such order and to appeal therefrom and shall cooperate reasonably with the Issuer or any Holder (or any holder of a beneficial interest in the Notes), as applicable, in opposing such court order and in securing confidential treatment of any such information to be disclosed and/or obtaining a protective order narrowing the scope of such disclosure.

63

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 9 upon the Issuer with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or of any officer or officers thereof required by the provisions of this Article 9; and if the Indenture Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Indenture Trustee.

SECTION 9.08. Release Upon Termination of the Issuer’s Obligations .
