Article VIII and Article X of the Base Indenture shall not apply to the Notes.  Instead, the discharge and defeasance provisions set forth in this Article V shall, with respect to the Notes, supersede in their entirety Article VIII and Article X of the Base Indenture.

Section 5.02                            Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights of registration of transfer or exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes issued hereunder (“Discharge”), when:

(a)                                 either:

(i)                                     all Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from their trust as provided in this Indenture) have been delivered to the Trustee for cancellation; or

(ii)                                  all the Notes that have not been delivered to the Trustee for cancellation will mature within one year and the Company 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, in the opinion of a nationally recognized investment bank or firm of independent public accountants delivered to the Trustee to pay the principal of, and interest on, the Outstanding Notes to the Maturity Date;

(b)                                 in respect of subclause (ii) of clause (a) of this Section 5.02, no Default or Event of Default has occurred and is continuing as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under any other instrument to which the Company is a party or by which the Company is bound;

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

(d)                                 the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of principal of, and interest on, the outstanding Notes to their maturity.

In addition, the Company must deliver an Officer’s Certificate and an Opinion of Counsel (subject to customary assumptions and exceptions) to the Trustee stating that all conditions precedent to satisfaction and discharge pursuant to this section have been satisfied.

Section 5.03                            Legal Defeasance.

The Company shall, subject to Section 5.09 and the satisfaction of the conditions set forth in Section 5.05, be deemed to have been discharged from its obligations with respect to the Notes on the date the conditions set forth in Section 5.05 are satisfied (“Legal Defeasance”).  For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Notes, which shall thereafter be deemed to be Outstanding only for the purposes of Section 5.06 hereof and the other Sections of this Supplemental Indenture referred to in Section 5.09 below, and to have satisfied all of its obligations under the Notes and the Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments delivered to it by the Company acknowledging the same). The Company may exercise Legal

11

Defeasance with respect to the Notes notwithstanding the prior exercise of Covenant Defeasance with respect to the Notes.

Section 5.04                            Covenant Defeasance.

The Company shall, subject to Section 5.09 and the satisfaction of the conditions set forth in Section 5.05, be released from its obligations under the covenants contained in Section 3.06 and in Article VII (other than Section 7.01(a)(y)) and, on and after the date that the conditions set forth in Section 5.05 are satisfied with respect to the Notes (“Covenant Defeasance”), the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in such covenants, whether directly or indirectly, by reason of any reference elsewhere herein to such covenants or by reason of any reference in such covenants to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.02, but, except as specified above, the remainder of the Indenture and the Notes shall be unaffected thereby.

Upon the Company’s exercise of Covenant Defeasance, subject to the satisfaction of the conditions set forth in Section 5.05 and the exceptions set forth in Section 5.09, clauses (c) through (d) of Section 6.02 shall not constitute Defaults or Events of Default hereunder.

Section 5.05                            Conditions to Legal or Covenant Defeasance.  In  order to exercise either Legal Defeasance or Covenant Defeasance:

(a)                                 The Company must irrevocably deposit, or cause to be deposited, with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank or firm of independent public accountants delivered to the Trustee, to pay principal of, and interest, on, the outstanding Notes to their maturity;

(b)                                 in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel by an independent U.S. tax counsel of recognized standing (subject to customary assumptions and exceptions) confirming that:

(i)                                     the Company has received from, or there has been published by, the Internal Revenue Service a ruling or

(ii)                                  since the Issue Date, there has been a change in the applicable federal income tax law,

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

(c)                                  in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel by an independent U.S. tax counsel of recognized standing (subject to customary assumptions and exceptions) confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d)                                 no Default or Event of Default shall have occurred and be continuing on the date of such deposit;

12

(e)                                  such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under this Indenture or any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(f)                                   the Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(g)                                  the Company must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel (subject to customary assumptions and exceptions), each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 5.06                            Application of Trust Money.

Subject to Section 5.07, the Trustee will hold in trust the money or Government Securities deposited with it pursuant to Section 5.02 or pursuant to Legal Defeasance or Covenant Defeasance, and apply the deposited money and the proceeds from deposited Government Securities to the payment of principal of and interest on the Notes (in the form of Installment Payments) in accordance with the Notes and the Indenture. Such money and Government Securities need not be segregated from other funds except to the extent required by law.

Section 5.07                            Repayment to Company.

Upon the satisfaction and discharge of the Indenture, all monies, if any, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies.

Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the Installment Payments with respect to the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the Installment Payments with respect to such Notes, shall have become due and payable, shall be repaid to the Company by the Trustee or the Paying Agent on demand, and all liability of the Trustee shall thereupon cease with respect to such monies; and the Holders shall thereafter look only to the Company for any payment that such Holder may be entitled to collect unless an applicable abandoned property law designates another person; provided, however, that before the Trustee or such Paying Agent are required to make any such repayment, the Company shall cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 5.08                            Reinstatement.

If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 5.06 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Sections 5.02 or 5.05, as the case may be, until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 5.06; provided, however, that if the Company makes any payment of interest on, principal of or payment in respect of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money, if any, held by the Trustee or Paying Agent.

Section 5.09                            Provisions to Survive Defeasance and Discharge.

Notwithstanding the foregoing and Sections 5.02, 5.03 and 5.04, no Discharge, Legal Defeasance or Covenant Defeasance pursuant to this Article V shall affect the following obligations to, or rights of, the Holders of the Notes:

13

(a)                                 the rights of registration of transfer and exchange of the Notes;

(b)                                 the Company’s obligations with respect to the Notes concerning mutilated, defaced, destroyed, lost or stolen Notes;

(c)                                  the rights of Holders of Notes to receive payments in respect of the principal thereof and interest thereon (in the form of Installment Payments), upon the original due dates therefor, but not upon acceleration;

(d)                                 the rights, indemnities and immunities of the Trustee, and the Company’s obligations in connection therewith;

(e)                                  the rights of Holders of Notes that are beneficiaries with respect to property so deposited with the Trustee payable to all or any of them;

(f)                                   the maintenance of an office or agency for payment and money for payments held in trust in respect of the Notes;

(g)                                  the rights and obligations under Article IX hereof; and

(h)                                 the provisions under Section 5.03 hereof.

ARTICLE VI
 DEFAULTS AND REMEDIES

Section 6.01                            Article VI of the Base Indenture.

Article VI of the Base Indenture shall not apply to the Notes.  Instead, this Article VI supersedes Article VI of the Base Indenture in its entirety, and references in the Base Indenture to provisions of Article VI thereof shall be deemed to be references to the corresponding provisions of this Article VI.

Section 6.02                            Events of Default.  Each of the following events shall be an “Event of Default” wherever used with respect to the Notes:

(a)                                 (i) failure by the Company to pay any Installment Payment on any Note when such is due which failure to pay is not cured within 30 days or (ii) failure by the Company to pay the Repurchase Price of any Note when due;

(b)                                 failure by the Company to give notice of a Fundamental Change when any such notice is due pursuant to the terms of the Purchase Contract Agreement;

(c)                                  failure by the Company to comply with any of its agreements or covenants in, or provisions of, the Notes or the Indenture, and such failure continues for 60 days after receipt by the Company of a Notice of Default;

(d)                                 default by the Company or any Material Subsidiary under any document evidencing any indebtedness for borrowed money by the Company or any Material Subsidiary, whether such indebtedness exists on the date of the Indenture or is created thereafter, if that default:

(i)                                     is caused by a failure to pay principal when due at final (and not any interim) maturity on or prior to the expiration of any grace period provided in such indebtedness (a “Payment Default”); or

(ii)                                  results in the acceleration of such indebtedness prior to its express maturity (without acceleration having been rescinded, annulled or otherwise cured),

14

and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated (without such acceleration having been rescinded, annulled or otherwise cured), aggregates $100.0 million or more; provided that this Section 6.02(d) shall not apply to (A) secured indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such indebtedness and (B) any indebtedness that is required to be converted into Qualifying Equity Interests upon the occurrence of certain designated events so long as no payments in cash or otherwise are required to be made in accordance with such conversion; or

(e)                                  a court of competent jurisdiction (i) enters an order or decree under any Bankruptcy Law that is for relief against the Company or any Material Subsidiary in an involuntary case; (ii) appoints a custodian for all or substantially all of the property of the Company or any Material Subsidiary; or (iii) orders the liquidation of the Company or any Material Subsidiary and, in each of clauses (i), (ii) or (iii), the order, appointment or decree remains unstayed and in effect for at least 60 consecutive days; or (b) the Company or any Material Subsidiary, pursuant to or within the meaning of Bankruptcy Law (i) commences a voluntary case; (ii) consents to the entry of an order for relief against it in an involuntary case; (iii) consents to the appointment of a custodian of it or for all or substantially all of its property; or (iv) makes a general assignment for the benefit of its creditors.

A Default as described in Section 6.02(c) above shall not be deemed an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the Notes then Outstanding notify the Company and the Trustee in writing, of the Default and the Company does not cure the Default within 60 calendar days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default” (such notice, a “Notice of Default”).

Section 6.03                            Acceleration; Rescission and Annulment.

(a)                                 Subject to Section 6.04(a), if one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be 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), then, and in each and every such case, unless the principal of all of the Notes shall have already become due and payable, the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then Outstanding, by notice in writing to the Company (and to the Trustee if given by the Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything in the Indenture or in the Notes contained to the contrary notwithstanding; provided, however, that if an Event of Default specified in Section 6.02(e) with respect to the Company (and not solely with respect to one or more Material Subsidiaries) occurs and is continuing, the Installment Payments on any Notes shall be immediately due and payable.

(b)                                 The Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Trustee, may waive all Defaults with respect to the Notes (other than a Default or an Event of Default resulting from a failure to pay the Installment Payments) and rescind and annul such declaration of acceleration resulting from such Defaults (other than a Default or an Event of Default resulting from a failure to pay the Installment Payments) and their consequences if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the Installment Payments that have become due solely by such declaration of acceleration, have been cured or waived then such Default (other than a Default or an Event of Default resulting from a failure to pay the Installment Payments) shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; provided, that no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

Section 6.04                            Additional Interest.

(a)                                 Notwithstanding any provisions of the Indenture to the contrary, during the first 180 days after the occurrence of an Event of Default relating to the Company’s failure to comply with Section 3.06 (a

15

“Reporting Event of Default”), the Company by notifying the Trustee, the Paying Agent and all of the Holders, in writing, on or before the Close of Business on the fifth Business Day immediately following the date on which such Event of Default otherwise would occur, may elect that the sole remedy of the Holders for such a Reporting Event of Default will consist exclusively of the right to receive additional interest on the Notes (“Additional Interest”) at a rate per year equal to (i) 0.25% of the Outstanding principal amount of the Notes for the first 90 days after the occurrence of such Reporting Event of Default and (ii) 0.50 % of the Outstanding principal amount of the Notes for the 90 days immediately following such 90-day period, payable in arrears on each Installment Payment Date following the date on which such Reporting Event of Default first occurs and in the same manner as regular interest on the Notes (which Additional Interest will, for the avoidance of doubt, result in an increase in the amount of any such Installment Payment). The Notes may not be accelerated during such five Business Day period following a Reporting Event of Default.

(b)                                 (x) On the 181st day after such Reporting Event of Default (if such violation is not cured or waived prior to such 181st day) or (y) if the Company does not elect to pay Additional Interest upon a Reporting Event of Default in accordance with Section 6.04(a) or fails to timely provide the notice of the Company’s election to pay Additional Interests pursuant to Section 6.04(a), the Notes will be subject to acceleration as described in Section 6.03.

Section 6.05                            Control by Majority.

At any time, the Holders of a majority of the aggregate principal amount of the Notes then Outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or, subject to the Trustee’s duties under Article VII of the Base Indenture and the TIA, that the Trustee determines to be unduly prejudicial to the rights of a Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the Trustee is offered indemnity or security satisfactory to it, in its sole discretion, against any loss, liability or expense to the Trustee that may result from the Trustee’s instituting such proceeding as the Trustee.  Prior to taking any action hereunder, the Trustee will be entitled to indemnification satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.06                            Limitation on Suits.  Subject to Section 6.07 hereof, no Holder may pursue a remedy with respect to the Indenture or the Notes unless:

(a)                                 such Holder has previously delivered to the Trustee written notice that an Event of Default has occurred and is continuing;

(b)                                 the Holders of at least 25% of the aggregate principal amount of the Notes then Outstanding have delivered to the Trustee a written request that the Trustee pursue a remedy with respect to such Event of Default;

(c)                                  such Holder or Holders have offered and, if requested, provided to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or other expense in compliance with such written request;

(d)                                 the Trustee has not complied with such written request within 60 days after receipt of such written request and offer of security or indemnity; and

(e)                                  during such 60-day period, the Holders of a majority of the aggregate principal amount of the Notes then Outstanding did not deliver to the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such written request.

A Holder may not use the Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of the Indenture by a Holder is unduly prejudicial to such other Holders.

16

Section 6.07                            Rights of Holders to Receive Installment Payments.

Notwithstanding anything to the contrary elsewhere in the Indenture, the right of any Holder to receive Installment Payments on its Notes, on or after the respective due date, or to bring suit for the enforcement of any such payment, will not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.06 hereof.

Section 6.08                            Collection of Indebtedness; Suit for Enforcement by Trustee.

If an Event of Default specified in Section 6.02(a) 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 Installment Payments on the Notes or Repurchase Price, as applicable, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 7.07 of the Base Indenture.

Section 6.09                            Trustee May Enforce Claims Without Possession of Notes.

All rights of action and claims under the Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

Section 6.10                            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 to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 of the Base Indenture.  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 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is 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 will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.11                            Restoration of Rights and Remedies.

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

17

Section 6.12                            Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.09 of the Base Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.13                            Delay or Omission Not a Waiver.

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

Section 6.14                            Priorities.

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

FIRST:  to the Trustee, its agents and attorneys for amounts due under Section 7.07 of the Base Indenture, 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 the Holders, for any amounts due and unpaid on the principal of and accrued and unpaid interest on any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes for principal and interest; and

THIRD:  the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.14.  If the Trustee so fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

Section 6.15                            Undertaking for Costs.

All parties to the Indenture agree, and each Holder, by such Holder’s acceptance of a Note, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 6.15 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder pursuant to Section 6.07, or to any suit by a group of Holders pursuant to Section 6.07, holding in the aggregate more than 10% in aggregate principal amount of the Notes then Outstanding.

Section 6.16                            Waiver of Stay, Extension and Usury Laws.

The Company covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or

18

advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted.

Section 6.17                            Notices from the Trustee.

Notwithstanding anything to the contrary in the Base Indenture, including Section 7.05, whenever a Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee must mail notice of such Default to the Holders within 90 days after the date on which such Default first occurred or if not known until after the 90th day, as soon as is reasonably practicable.  Except in the case of a Default in the payment of an Installment Payment on any Note, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interests of the Holders.

ARTICLE VII
CONSOLIDATION, MERGER, SALE OR CONVEYANCE

Section 7.01                            Covenant Not to Consolidate or Merge, Convey, Transfer or Lease Property Except Under Certain Conditions.  Article V of the Base Indenture shall not apply with respect to the Notes, and this Article VII supersedes the entirety thereof, with respect to the Notes.  With respect to the Notes, references in the Base Indenture to Article V of the Base Indenture are deemed replaced with references to this Article VII.

The Company shall not (1) consolidate or merge with or into another Person or (2) sell, assign, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Company and its Subsidiaries taken as a whole to another Person unless:

(a)                                 the successor entity (the “Successor Company”), if not the Company, is (and, if the Company remains a party to the Notes and the Indenture after giving effect to such transaction and the requirements in respect thereof under the Indenture) a corporation organized and existing under the laws of the United States, any state of the United States or the District of Columbia, and the Successor Company, if not the Company, expressly assumes all of the obligations of the Company under the Notes and the Indenture pursuant to agreements reasonably satisfactory to the Trustee;

(b)                                 the obligor under the Indenture will not, immediately after the relevant transaction, be in default in the performance of its covenants and conditions under the Units or the Notes; and

(c)                                  the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, subject to customary qualifications and assumptions, each stating that such transaction and such modifications to the Indenture, if any, comply with the requirements therefor under this Article VII.

(b)                                 If the Trustee holds money on the Repurchase Date sufficient to pay the Repurchase Price with respect to those Notes for which the Repurchase Right has been exercised, then (i) such Notes shall cease to be outstanding and interest shall cease to accrue thereon (whether or not book-entry transfer of the Notes or Units, as applicable, is made or whether or not the Notes or Units, as applicable, are delivered as required herein), and (ii) all other rights of the Holder shall terminate (other than the right to receive the Repurchase Price and, if the Repurchase Date falls between a Regular Record Date and the corresponding Installment Payment Date, the related Installment Payment); provided, however, that if the Repurchase Date falls after a Regular Record Date and on or prior to the immediately succeeding installment Payment Date, then the Installment Payment payable on such Installment Payment Date will be paid on such Installment Payment Date to the Holder as of the Close of Business on such Regular Record Date and shall be deducted from the Repurchase Price per note.

(c)                                  The Company shall, in connection with any repurchase offer pursuant to this Article IX, if required by applicable provisions of the Exchange Act or SEC regulations thereunder, (i) comply with the provisions of the tender offer rules under the Exchange Act that may then be applicable, and (ii) file a Schedule TO or any other required schedule under the Exchange Act.

(d)                                 Notwithstanding anything to the contrary herein, no Notes may be repurchased at the option of Holders if the principal amount thereof has been accelerated, and such acceleration has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Repurchase Price with respect to such Notes).

CUSIP No.: 26817R306

ISIN No.: US26817R3066

Dynegy Inc., a Delaware corporation (the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the initial principal sum of $18.94911 for each of the number of Notes set forth [above][in Schedule A hereto], in quarterly installments of $1.7500 per Note (except for the October 1, 2016 installment, which shall be $1.94444 per Note) (each such payment, an “Installment Payment,” constituting a payment of interest at the rate per year of 7.00% and a partial repayment of principal) payable on each January 1, April 1, July 1 and October 1, commencing on October 1, 2016 (each such date, an “Installment Payment Date” and the period from, and including, June 21, 2016 to, but excluding, the first Installment Payment Date and each subsequent full quarterly period from and including an Installment Payment Date to, but excluding, the immediately succeeding Installment Payment Date, an “Installment Payment Period”), all as set forth on the reverse hereof.  Notwithstanding the foregoing, the amount of any Installment Payment for any Installment Payment Period shall be increased by the amount of additional interest, if any, payable for such Installment Payment Period as provided in the Indenture hereinafter referred to.

The Installment Payment on any Installment Payment Date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. If an installment is payable for any period shorter or longer than a full Installment Payment Period, such installment shall be computed on the basis of the actual number of days elapsed per 30-day month. In the event that any date on which an installment is payable is not a Business Day, then payment of the installment on such date will be made on the next succeeding day that is a Business Day, and without any interest or other payment in respect of any such delay. However, if such Business Day is in the next succeeding calendar year, then such Installment Payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date when such Installment Payment was originally due.

Installment Payments shall be paid to the person in whose name the Note is registered, with limited exceptions, at the Close of Business on the March 15, June 15, September 15 or December 15, as applicable, immediately preceding the relevant Installment Payment Date.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to or be valid or obligatory for any purpose until the Certificate of Authentication shall have been signed by or on behalf of the Trustee.

[REVERSE OF NOTE]

DYNEGY INC.

This Amortizing Note is one of a duly authorized series of Securities of the Company designated as its 7.00% Senior Amortized Notes due 2019 (herein sometimes referred to as the “Notes”), issued under the indenture, dated as of June 21, 2016, between the Company and Wilmington Trust, National Association, as trustee (the “Trustee,” which term includes any successor trustee under the Indenture) (the “Base Indenture”) as supplemented by the First Supplemental Indenture, dated as of June 21, 2016, between the Company and the Trustee (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that securities of a single series may be issued at various times, with different maturity dates and may bear interest at different rates. This series of Securities is limited in aggregate principal amount as specified in the Supplemental Indenture.

Each Installment Payment shall constitute a payment of interest (at a rate of 7.00% per annum) and a partial repayment of principal on the Note, allocated as set forth in the schedule below:

Notwithstanding the foregoing, the amount of any Installment Payment for any Installment Payment Period shall be increased by the amount of additional interest, if any, payable for such Installment Payment Period as provided in the Indenture.

The Notes shall not be subject to redemption at the option of the Company, and no sinking fund is provided for the Notes.  However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note, and on the Repurchase Date, upon the occurrence of certain events, and subject to the conditions set forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund. The Indenture contains provisions for legal defeasance and covenant defeasance at any time of the Indenture and this Note upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, then (unless no declaration of acceleration or notice is required for such Event of Default) either the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding may declare all future, scheduled Installment Payments to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

A-5

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the holders of a majority in principal amount of the Notes at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

Obligations Unconditional. No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay Installment Payments, if applicable, on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

Additional Terms. The Notes are originally being issued as part of the Company’s 7.00% Tangible Equity Units (the “Units”) issued pursuant to that certain Purchase Contract Agreement, dated as of June 21, 2016, between the Company, and Wilmington Trust, National Association, as Purchase Contract Agent and as Trustee of the Indenture (the “Purchase Contract Agreement”).  Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances described in the Purchase Contract Agreement. Following separation of any Unit into its constituent Separate Purchase Contract and Separate Note, the Separate Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase Contract Agreement for a more complete description of the terms thereof applicable to the Units and Notes.

Transfer and Exchange. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note shall be registered on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in the continental United States, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or by his or her attorney duly authorized in writing, and thereupon the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Note or Notes in authorized denominations and for a like aggregate principal amount.

The Notes are initially issued in registered, global form without coupons in denominations initially equal to $18.94911 and integral multiples in excess thereof.

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

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Issuer or the Trustee may treat the Holder in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Note and the Indenture, and any claim, controversy or dispute arising under or related to the Indenture or this Note, shall be governed by, and construed in accordance with, the laws of the State of New York.

All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

No recourse shall be had for the payment of any Installment Payment on this Note, or for any claim based hereon, or upon any obligation, covenant or agreement of the Company in the Indenture, against any incorporator, stockholder, officer or director, past, present or future of the Company or of any predecessor or successor corporation, either directly or through the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released and waived as a condition of, and as part of the consideration for, the issuance of this Note.

A-6

The Company, each Holder and each Beneficial Owner (for U.S. federal income tax purposes) by its acquisition of a beneficial interest in the Notes agrees, for U.S. federal income tax purposes, to treat the Notes as indebtedness of the Company.

A copy of the Indenture is available for inspection at the office of the Trustee.
