SECTION 2.09 Transfer and Exchange. The Securities shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and any reasonable regulations prescribed by the Company or the Registrar are met. When Securities (other than Global Securities) are presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.

To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate at the Registrar’s request one or more new Securities of any authorized denominations and of a like aggregate principal amount and tenor.

No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange not involving any transfer pursuant to Section 3.07).

The Registrar shall not be required to register the transfer of or exchange of any Security for a period beginning 15 Business Days before the mailing of a notice of redemption or of an offer to repurchase Securities and ending at the close of business on the date of such mailing, or for a period beginning 15 Business Days before an interest payment date and ending on the close of business on such interest payment date, or of any Security selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee and any Agent may deem and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of, and any premium and interest on, such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee or any Agent shall be affected by notice to the contrary.

All Securities issued upon any registration of transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

The 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 Security (including any transfers between or among Agent Members or beneficial owners of interests in any Global Security) 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.

SECTION 2.10 Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the Holder satisfies the reasonable requirements of the Company and the Trustee. If required by the Company or the Trustee, such Holder shall furnish an indemnity bond or other security sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

SECTION 2.11 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Except to the extent provided in the last paragraph of this Section 2.11, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.10, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser.

If the Paying Agent holds on a redemption date or the Maturity Date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

Securities with respect to which the Company has effected legal defeasance or covenant defeasance as provided in Article Eight cease to be outstanding except to the extent provided in Sections 8.03 and 8.04.

In determining whether the Holders of the requisite principal amount of the outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which a Responsible Officer actually knows to be so owned shall be so disregarded. Securities so owned as described in the immediately preceding sentence which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor.

SECTION 2.12 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

(a) For all Securities that are to be issued in whole or in part in the form of one or more Global Securities, any such Global Security shall represent such of the outstanding Securities as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, transfers or redemptions. Any endorsement of a Global Security to reflect the amount, or any increase or decrease in the amount, of outstanding Securities represented thereby shall be made by the Trustee (i) in such manner and upon instructions given by such Person or Persons as shall be specified in such Security or in a Company Order to be delivered to the Trustee pursuant to Section 2.05 or (ii) otherwise in accordance with written instructions from the Depositary or its nominee on behalf of any Person having a beneficial interest in such Global Security. Any such Global Security shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, shall be delivered by the Trustee or its agent to the Depositary or pursuant to the Depositary’s instruction and shall bear a legend substantially to the following effect (or to such effect as may be required by the Depositary):

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO., OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC) ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

(b) Members of, or participants, including Clearstream and Euroclear as indirect participants, in, the Depositary (“Agent Members”), and any owner of a beneficial interest in a Global Security, shall have no rights under this Indenture with respect to or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depositary or its nominee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

(c) Notwithstanding any other provision in this Indenture, no Global Security may be transferred to, or registered or exchanged for Securities registered in the name of, any Person other than the Depositary for such Global Security or any nominee thereof, and no such transfer may be registered, except as provided in this Section 2.13(c). Every Security authenticated and delivered upon registration or transfer of, or in exchange for or in lieu of, a Global Security shall be a Global Security, except as provided in this Section 2.13(c). If (1) (A) the Depositary for a Global Security notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or ceases to be a clearing agency registered under the Exchange Act, and (B) a successor Depositary is not appointed by the Company within 90 days, (2) an Event of Default has occurred and is continuing with respect to the Securities and the Registrar has received a request from the Depositary to issue certificated securities (“Certificated Securities”) in lieu of all or a portion of the Global Securities (in which case the Company shall deliver Certificated Securities within 30 days of such request) or (3) the Company determines in its sole discretion and notifies the Trustee that Securities issued in global form shall no longer be represented by a Global Security, then such Global Security may be exchanged by such Depositary for Certificated Securities of any authorized denomination and of a like aggregate principal amount and tenor, registered in the names of, and the transfer of such Global Security or portion thereof may be registered to, such Persons as such Depositary shall direct, in each case, in accordance with the procedures set forth in the Appendix.

(d) Neither the Company nor the Trustee shall have any responsibility or obligation to any beneficial owner of a Global Security, or interest therein, Agent Member or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Agent Member, with respect to any ownership interest in Global Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Holder of the Global Security or the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery and the respective principal amounts, of the Securities to be issued).

(e) Neither the Company, the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

SECTION 2.14 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation in its customary manner and upon written request shall deliver a certificate of such cancellation to the Company. Any Securities purchased by the Company may, to the extent permitted by law, be reissued or resold or may, at its option, be surrendered to the Trustee for cancellation. The Company may not issue new Securities to replace Securities it has delivered to the Trustee for cancellation, except as expressly permitted by the terms of the Securities.

SECTION 2.15 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) at the rate borne by the Securities in any lawful manner. In the event that the Company is required to pay defaulted interest to Holders, the Company will provide written notice to the Trustee of its obligation to pay such defaulted interest no later than five days prior to the proposed payment date for the defaulted interest, and such notice shall set forth the amount of defaulted interest to be paid by the Company on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine the defaulted interest, or with respect to the nature, extent, or calculation of the amount of defaulted interest owed, or with respect to the method employed in such calculation of the defaulted interest. The Company may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.16 CUSIP Numbers and ISINs. The Company in issuing the Securities may use “CUSIP” numbers and/or “ISINs” (if then generally in use) and, if so, the Trustee shall use CUSIP numbers and/or ISINs in notices of redemption or repurchase 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 Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers and/or ISINs.

(a) Except as set forth in this Section 3.01(a), the Company shall not be entitled to optionally redeem the Securities prior to December 15, 2018.

(1) At any time prior to December 15, 2018, the Company will be entitled at its option to redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus the Make-Whole Premium as of, and accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), in accordance with paragraph 4 of the Securities.

(2) At any time prior to December 15, 2018, the Company will be entitled at its option on any one or more occasions to redeem up to 35% of the aggregate principal amount of Securities issued under this Indenture at a redemption price equal to 108.0% of the principal amount of the Securities redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings by the Company; provided that, with respect to each such redemption:

(A) at least 65% of the aggregate principal amount of Securities issued under the Indenture (excluding any Securities held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(B) such redemption occurs within 180 days of the date of the closing of such Equity Offering.

(b) At any time on or after December 15, 2018, the Company may redeem the Securities, in whole or in part, at its option, at the redemption prices set forth in paragraph 5(a) of the Securities, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), in accordance with paragraph 5 of the Securities.

(c) The Trustee shall have no responsibility or obligation whatsoever to calculate the Adjusted Treasury Rate or the Make-Whole Premium in connection with any redemption. The Company will calculate the Adjusted Treasury Rate and the Make-Whole Premium and, prior to the redemption date, deliver an Officers’ Certificate to the Trustee setting forth the Adjusted Treasury Rate and the Make-Whole Premium and showing the calculation of each in reasonable detail.

SECTION 3.02 Notice to Trustee. If the Company elects to redeem all or any part of the Securities pursuant to the applicable provisions of this Article 3 and the Securities, it shall furnish to the Trustee and the Registrar, at least 30 days but not more than 60 days before the redemption date (unless the Trustee consents to a shorter period), an Officers’ Certificate setting forth the redemption date, the principal amount of Securities to be redeemed and the redemption price (or the manner of calculation thereof) for Securities to be redeemed.

SECTION 3.03 Selection of Securities to Be Redeemed. If less than all of the Securities are to be redeemed at any time, the Trustee shall select the particular Securities to be redeemed on a pro rata basis, in accordance with the procedures of the Depositary, or, if the Securities are listed on any securities exchange, by any other method that complies with the requirements of such exchange; provided, however, that no Securities with a principal amount of $2,000 or less will be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption not less than 30 nor more than 60 days prior to the redemption date. Securities and portions of them it selects shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof, except that if all of the Securities of a Holder are

to be redeemed, the entire outstanding amount of such Securities held by such Holder, even if not a multiple of $1,000, shall be redeemed. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities selected for redemption.

(a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address or send such notice in accordance with the Depositary’s applicable procedures. The notice shall state:

(2) the redemption price or, if the redemption price is not then determinable, the manner in which it is to be determined;

(5) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the redemption price, together with any accrued and unpaid interest thereon;

(6) that, unless the Company defaults in the payment of the redemption price, accrued interest on Securities called for redemption ceases to accrue on and after the redemption date and the only remaining right of the Holders is to receive payment of the redemption price in respect of the Securities upon surrender to the Paying Agent of the Securities;

(7) if fewer than all of the outstanding Securities are to be redeemed, the identification of the particular Securities to be redeemed, and if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date, upon surrender of such Security, in the case of a Certificated Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the Security or Securities being redeemed;

(10) the paragraph of the Security and/or Section of this Indenture pursuant to which the Securities called for redemption are being redeemed.

(b) At the Company’s written request, the Trustee shall give the notice of redemption required in Section 3.04(a) in the Company’s name and at the Company’s expense; provided, however, that the Company shall deliver to the Trustee, at least 15 days prior to the date on which the Company requests that the Trustee give such notice (unless the Trustee consents to a shorter notice period), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.04(a).

(c) Notice of any redemption, including, without limitation, upon an Equity Offering, may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

SECTION 3.05 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.04, Securities called for redemption become due and payable on the redemption date at the redemption price, subject to the satisfaction of any conditions precedent specified in the notice. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price, plus accrued and unpaid interest to, but not including, the redemption date; provided, however, that installments of interest that are due and payable on or prior to the redemption date shall be payable to the Holders of such Securities, registered as such, at the close of business on the relevant record date for the payment of such installment of interest. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.06 Deposit of Redemption Price. Prior to 10:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) funds available on the redemption date sufficient to pay the redemption price of, and accrued and unpaid interest to, but not including, the redemption date on, the Securities to be redeemed on that date. The Paying Agent shall promptly return to the Company any money so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven.

Unless the Company defaults in making such payment, interest on the Securities to be redeemed will cease to accrue on the applicable redemption date, whether or not such Securities are presented for payment. If any Security called for redemption shall not be so paid upon redemption because of the failure of the Company to comply with the preceding paragraph, interest will continue to be payable on the unpaid principal and any premium including from the redemption date until such principal and any premium is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 4.01 hereof.

SECTION 3.07 Securities Redeemed in Part. Upon surrender of a Security that is to be redeemed in part, in the case of a Certificated Security, the Company shall issue and the Trustee upon receipt of a Company Order shall authenticate for the Holder, at the expense of the Company, a new Security equal in aggregate amount to the unredeemed portion of the Security surrendered.

(a) Except as set forth in Section 3.08(b), the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities, nor (except pursuant to Section 4.10 and Section 4.11) shall the Company be required to repurchase the Securities at the option of the Holders.

(b) If the Securities would otherwise constitute “applicable high yield discount obligations” (“AHYDOs”) within the meaning of Section 163(i)(1) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), at the end of all accrual periods ending after the fifth anniversary of the Issue Date (each, an “AHYDO Payment Date”), but not including the final accrual period, the Company will make pro-rata cash payments to all Holders of the Securities then outstanding in an amount equal to the Mandatory Principal Payment Amount (each such payment, a “Mandatory Principal Payment”). The “Mandatory Principal Payment Amount” means the portion of the Securities’ principal required to be paid as of each AHYDO Payment Date to prevent the Securities from being treated as an AHYDO within the meaning of Section 163(i)(1) of the Code. No partial payments, redemptions or repurchases of the Securities prior to an AHYDO Payment Date pursuant to any other provision of this Indenture or the Securities will alter the Company’s obligation to make the Mandatory Principal Payment with respect to the Securities that remain outstanding on an AHYDO Payment Date. Solely for U.S. federal income tax purposes, any Mandatory Principal Payment shall be treated as a payment of accrued original issue discount that constitutes interest for purposes of Section 163(i)(2) of the Code. Any Mandatory Principal Payment paid with respect to Global Securities will be processed as a “partial redemption” through the Depositary, in accordance with its rules and procedures as a “Pro Rata Pass-Through Distribution of Principal.” Any Mandatory Principal Payment shall otherwise be made pursuant to the provisions of Sections 3.02 through 3.07.

SECTION 4.01 Payment of Securities. The Company, for the benefit of the Holders of Securities, shall pay the principal of, and any premium and interest on, the Securities on the dates and in the manner provided in the terms of the Securities and this Indenture. Principal or redemption price, and any premium and interest with respect to the Securities, shall be considered paid on the date due if the Trustee or Paying Agent holds by 10:00 a.m., New York City time, on that date money deposited by the Company designated for and sufficient to pay such principal, redemption price, premium and interest as is then due.

The Company, for the benefit of the Holders of Securities, shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, and any premium, at the rate borne by the Securities to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

SECTION 4.02 SEC Reports. Notwithstanding that the Company may not be required to remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company, within 15 days after it files the same with the SEC, shall deliver to the Trustee copies of the annual reports and the information, documents and other reports (or copies of any such portions of any of the foregoing as the SEC may by rules and regulations prescribe) specified in Section 13 or 15(d) of the Exchange Act; provided that any such annual reports, information, documents or other reports filed with or furnished to the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or “EDGAR”) system shall be deemed to be delivered to the Trustee as of the time such information, documents or reports are filed or furnished via EDGAR; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the EDGAR system (or its successor). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

(a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, an Officers’ Certificate, stating that a review of the activities of the Company and the Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each of the Company and the Subsidiary Guarantors has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that, to the best of such Officers’ knowledge, each of the Company and the Subsidiary Guarantors has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officers may have knowledge and what action the Company is taking or proposes to take with respect thereto).

(b) The Company will, so long as any of the Securities are outstanding, deliver to the Trustee within 30 days after any Officer becoming aware of any Default or Event of Default or default in the performance of any covenant, agreement or condition contained in this Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company proposes to take with respect thereto.

SECTION 4.04 Maintenance of Office or Agency. The Company will maintain in each Place of Payment an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment, and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company

will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 13.02 or at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby initially designates as the Place of Payment for the Securities The City of New York, and initially appoints the Trustee as Paying Agent at its Corporate Trust Office as the Company’s office or agency for each such purpose in such city.

SECTION 4.05 Continued Existence. Except as permitted by Article Five and Section 10.03 hereof, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Restricted Subsidiary and all rights (charter and statutory) and franchises of the Company and the Restricted Subsidiaries; provided, that the Company shall not be required to preserve the corporate, partnership or other existence of any Restricted Subsidiary, or any such right or franchise, if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 4.06 Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants (to the extent that each may lawfully do so) that 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 or other law which would prohibit or forgive the Company or any Subsidiary Guarantor from paying all or any portion of the principal of, and any premium and interest on, the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 4.07 Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Restricted Subsidiary or upon the income, profits or property of the Company or any Restricted Subsidiary and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Company or any Restricted Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge whose amount, applicability or validity is being contested in good faith by appropriate proceedings or where the failure to effect such payment is not disadvantageous in any material respect to the Holders.

(a) The Company shall cause all properties used or held for use in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order (ordinary wear and tear excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 4.08 shall prevent the Company from discontinuing the operation or maintenance of any such property, or disposing of it, if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders.

(b) The Company shall provide or cause to be provided, for itself and each of its Restricted Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the reasonable, good faith opinion of the Company, are adequate and appropriate for the conduct of the business of the Company and such Restricted Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Company, for corporations similarly situated in the industry.

(a) The Company (i) will not, and will not permit any Restricted Subsidiary to, create, incur or assume any Funded Debt secured by any Liens (other than Permitted Liens) upon any of the properties of the Company or any Restricted Subsidiary and (ii) will not, and will not permit any Subsidiary to, create, incur or assume any Funded Debt secured by any Liens (other than Permitted Liens) upon the Capital Stock of any Restricted Subsidiary or the Capital Stock of any Subsidiary that owns, directly or indirectly through ownership in another Subsidiary, the Capital Stock of any Restricted Subsidiary.

(b) Notwithstanding the provisions of Section 4.09(a), the Company or any Subsidiary may create, incur or assume Funded Debt secured by Liens (including the Securities) which would otherwise be subject to the restrictions of such section, if the aggregate principal amount of such Funded Debt and all other Funded Debt of the Company and any Subsidiary theretofore created, incurred or assumed pursuant to the exception in this Section 4.09(b) and outstanding at such time does not exceed 15% of the Adjusted Consolidated Net Tangible Assets of the Company, less, without duplication, the outstanding principal amount of the Securities outstanding at such time.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Subsidiary) unless (i) the Company or such Restricted Subsidiary, as the case may be, would be entitled to incur Funded Debt secured by Liens in a principal amount equal to the Attributable Indebtedness (treated as if such Attributable Indebtedness were Funded Debt) with respect to such Sale/Leaseback Transaction in accordance with Section 4.09 or (ii) the Company or such Restricted Subsidiary receives proceeds from such Sale/Leaseback Transaction at least equal to the Fair Market Value thereof and such proceeds are applied in accordance with paragraphs (b) to (c) hereof (or, in the case of a Sale/Leaseback Transaction that constitutes a Collateral Sale, such proceeds are applied in accordance with Section 4.11); provided, however, that Attributable Indebtedness in respect of any Sale/Leaseback Transaction entered into pursuant to clause (i) shall not count against the amount of Funded Debt permitted under Section 4.09(b) for any other purpose, including when determining the amount available thereunder for future Sale/Leaseback Transactions or any Funded Debt transactions.

(b) The Company may apply Net Available Proceeds from such Sale/Leaseback Transaction, within 365 days after receipt of Net Available Proceeds from the Sale/Leaseback Transaction, to: (i) the repayment of Indebtedness of the Company or a Restricted Subsidiary under Credit Facilities or other Senior Indebtedness, including any mandatory redemption or repurchase or make-whole redemption of the Existing Unsecured Notes or the Securities; (ii) make an Investment in assets used in the Oil and Gas Business; or (iii) develop by drilling the Company’s oil and gas reserves.

(c) If, upon completion of the 365-day period referred to in Section 4.10(b), any portion of the Net Available Proceeds (other than Net Cash Proceeds of a Sale/Leaseback Transaction that constitutes a Collateral Sale) shall not have been applied by the Company as described in clauses (i), (ii) or (iii) of Section 4.10(b) and such remaining Net Available Proceeds, together with any remaining net cash proceeds from any prior Sale/Leaseback Transaction (such aggregate constituting “Excess Proceeds”), exceed $60,000,000, then the Company will be obligated to make an offer (the “Net Proceeds Offer”) to purchase the Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer having an aggregate principal amount equal to the Excess Proceeds (such purchase to be made on a pro rata basis if the amount available for such repurchase is less than the principal amount of the Securities and other Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest on the Securities and other Senior Indebtedness so repurchased to the date of repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess Proceeds will be reset to zero.

(d) Within 15 days after the Company becomes obligated to make a Net Proceeds Offer (a “Net Proceeds Offer Triggering Event”), the Company (with notice to the Trustee and the Paying Agent), or the Trustee at the Company’s request and expense, will mail or cause to be mailed (or otherwise communicate in accordance with the applicable procedures of the Depositary) to all Holders on the date of the Net Proceeds Offer Triggering Event a notice prepared by the Company (the “Offer Notice”) of the occurrence of such Net Proceeds Offer Triggering Event and of the Holders’ rights arising as a result thereof. The Offer Notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The Offer Notice, which shall govern the terms of the Net Proceeds Offer, shall state: (1) that the Net Proceeds Offer is being made pursuant to this Section 4.10; (2) the purchase

price and the Net Proceeds Payment Date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest on the Net Proceeds Payment Date; (5) that Holders will be entitled to withdraw their election if the Company, Depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Net Proceeds Offer, or such longer period as may be required by law, a notice to such effect in the form specified in the Offer Notice; and (6) that Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered. The Net Proceeds Offer shall be deemed to have commenced upon mailing (or other communication in accordance with the applicable procedures of the Depositary) of the Offer Notice and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law.

(e) Promptly after the termination of the Net Proceeds Offer (the “Net Proceeds Payment Date”), the Company shall, to the extent permitted by applicable law, (i) accept for payment Securities or portions thereof tendered pursuant to the Net Proceeds Offer, (ii) deposit with the Depositary or Paying Agent money sufficient to pay the purchase price of all Securities or portions thereof so tendered and (iii) deliver to the Trustee Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. The Depositary, the Company or the Paying Agent, as the case may be, shall promptly mail or deliver to the Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.10(e)), and the Trustee shall promptly authenticate and mail or deliver to each such Holder a new Security equal in principal amount to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. For purposes of this Section 4.10, the Trustee shall act as the Paying Agent.

(f) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the Net Proceeds Offer procedures included in this Indenture, the Company shall comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the Net Proceeds Offer provisions of this Indenture by virtue of such compliance.

(a) The Company will not, and will not permit any of the other Mortgagors to, consummate a Collateral Sale, unless:

(1) the Mortgagor receives consideration at the time of such Collateral Sale at least equal to the Fair Market Value of the Collateral sold or otherwise disposed of (whether directly or indirectly through the sale or disposition of a Mortgagor); and

(2) at least 75% of the consideration received by the Company and the Mortgagors (determined on the date of contractually agreeing to such Collateral Sale) and all other Collateral Sales since the Issue Date, on a cumulative basis, is in the form of cash or Cash Equivalents; provided that the following shall be deemed to be Cash Equivalents for purposes of this clause (2) and for no other purpose:

(A) any liabilities (as shown on the Company’s most recent consolidated balance sheet or in the footnotes thereto or if incurred or accrued subsequent to the date of such balance sheet, such liabilities as would have been reflected in the Company’s consolidated balance sheet or the footnotes thereto if such incurrence or accrual had been put in place on or prior to the date of such balance sheet, as determined in good faith by the Company), other than contingent liabilities or liabilities that are by their terms subordinated to the Securities or the Guarantee, which (i) are assumed by the transferee of any such assets and from which the Company or other Mortgagor shall have been validly released by all applicable creditors in writing or (ii) that are otherwise cancelled or terminated in connection with the transaction with such transferee (other than intercompany debt owed to the Company or the Subsidiaries);

(B) any securities, notes or other obligations or assets received by the Company or any other Mortgagor from such transferee that are converted by the Company or such other Mortgagor into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received) within 180 days following the closing of such Collateral Sale;

(C) with respect to any Collateral Sale of Oil and Gas Properties by any Mortgagor in which such Mortgagor retains an interest in such property (whether directly or indirectly through retentions of any Equity Interests in any Person owning such property), the costs and expenses related to the exploration, development, completion or production of such Oil and Gas Properties and activities related thereto agreed to be assumed by the transferee (or an Affiliate thereof);

(D) Indebtedness of any Mortgagor that ceases to be a Mortgagor as a result of such asset disposition (other than intercompany debt owed to the Company or the Subsidiaries), to the extent that the Company and each other Subsidiary Guarantor are released from any guarantee of payment of the principal amount of such Indebtedness in connection with such Collateral Sale; and

(E) any Designated Non-Cash Consideration received by the Company or any other Mortgagor in respect of the applicable Collateral Sale having an aggregate Fair Market Value, taken together with all other Designated Non-Cash Consideration received pursuant to this clause (E) at any time outstanding, not to exceed the greater of (x) $500,000,000 and

(y) 10% of ACNTA determined as of the time of the receipt of such Designated Non-Cash Consideration, with the Fair Market Value of each item of Designated Non-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

(b) Within 365 days after the receipt of any Net Cash Proceeds, the Company or any of the other Mortgagors may apply such Net Cash Proceeds at its option:

(1) to permanently prepay, repay, redeem, defease or repurchase Priority Lien Debt and other outstanding Priority Lien Obligations;

(2) to permanently prepay, repay, redeem, defease or repurchase Parity Lien Debt and other outstanding Parity Lien Obligations other than Indebtedness owed to the Company or another Subsidiary; provided that if the Company shall so prepay, repay, redeem, defease or repurchase any such Parity Lien Debt, the Company shall equally and ratably repay (or offer to repay) the Securities as provided either, at the Company’s option, under Section 3.01, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth in this Section 4.11 for a Collateral Sale Offer) to all Holders to purchase their Securities at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Securities that would otherwise be prepaid;

(3) to acquire all or substantially all of the assets of, or a division or line of business of, any Person engaged in an Oil and Gas Business, or any Capital Stock of any Person engaged in an Oil and Gas Business, if, after giving effect to any such acquisition of Capital Stock, such Person is or becomes a Subsidiary Guarantor;

(4) to make capital expenditures or to make other expenditures for leasehold or seismic purposes, or for maintenance, repair or improvement of existing properties and assets;

(5) to acquire other assets that are used or useful in an Oil and Gas Business, including Oil and Gas Properties; or

provided that in the case of clauses (3), (4) and (5) above (or combination thereof), a binding commitment to make such acquisitions or expenditures is entered into within 365 days of the consummation of the Collateral Sale that generated the Net Cash Proceeds shall be treated as a permitted application of the Net Cash Proceeds from the date of such commitment so long as such Mortgagor enters into such commitment with the good faith expectation that such Net Cash Proceeds will be applied to satisfy such commitment within 545 days after the consummation of the Collateral Sale that generated such Net Cash Proceeds and, in the event such commitment is later cancelled or terminated for any reason before the Net Cash Proceeds are applied in connection therewith, then such Net Cash Proceeds shall constitute Excess Collateral Proceeds as described herein as of the date of such cancellation or termination.

(c) Any Net Cash Proceeds from Collateral Sales that are not applied or invested as provided in Section 4.11(b) will constitute “Excess Collateral Proceeds.” When the aggregate amount of Excess Collateral Proceeds exceeds $60,000,000, the Company will, within 45 days, make an offer to all Holders, and, if required by the terms of other Parity Lien Debt containing provisions similar to those set forth in this Section 4.11 with respect to offers to purchase or redeem with the proceeds of sales of assets, to all holders of such other similar Parity Lien Debt (a “Collateral Sale Offer”) to purchase the maximum principal amount of Securities and/or such Parity Lien Debt that may be purchased out of the Excess Collateral Proceeds. The offer price in any Collateral Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, to, but excluding, the date of purchase, and will be payable in cash.

(d) The Company shall commence a Collateral Sale Offer by mailing (with notice to the Trustee and the Paying Agent), or the Trustee at the Company’s request and expense, mailing or causing to be mailed (or otherwise communicating in accordance with the applicable procedures of the Depositary) to all Holders, a notice prepared by the Company of the Collateral Sale Offer and of the Holders’ rights arising as a result thereof. The notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The notice, which shall govern the terms of the Collateral Sale Offer, shall state: (1) that the Collateral Sale Offer is being made pursuant to this Section 4.11; (2) the purchase price and the payment date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Collateral Sale Offer shall cease to accrue interest on the payment date; (5) that Holders will be entitled to withdraw their election if the Company, Depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Collateral Sale Offer, or such longer period as may be required by law, a notice to such effect in the form specified in the Collateral Sale Offer; and (6) that Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered. The Collateral Sale Offer shall be deemed to have commenced upon mailing (or other communication in accordance with the applicable procedures of the Depositary) of the notice and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law. If the aggregate principal amount of Securities and other Parity Lien Debt tendered into such Collateral Sale Offer exceeds the amount of Excess Collateral Proceeds, the Excess Collateral Proceeds will be allocated between the Securities and such other Parity Lien Debt based on the principal amount (or accreted value, if applicable) of the Securities and such other Parity Lien Debt tendered and the Trustee will select the Securities to be purchased in the manner described in Section 4.11(g). Upon completion of each Collateral Sale Offer, the amount of Excess Collateral Proceeds will be reset at zero.

(e) Pending the final application of any Net Cash Proceeds pursuant to this Section 4.11, the holder of such Net Cash Proceeds may apply such Net Cash Proceeds temporarily to reduce obligations under a revolving credit facility or otherwise invest such Net Cash Proceeds in any manner not prohibited by the Indenture. If any Excess Collateral Proceeds remain after consummation of the Collateral Sale Offer, the Company may use those funds for any purpose not otherwise prohibited by the Indenture and they will no longer constitute Excess Collateral Proceeds.

(f) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Collateral Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Collateral Sale Offer procedures included in the Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the Collateral Sale provisions of the Indenture by virtue of such compliance.

(g) If the aggregate principal amount of Securities and Parity Lien Debt validly tendered and not properly withdrawn pursuant to a Collateral Sale Offer exceeds the amount of Excess Collateral Proceeds, the Trustee shall select the Securities and the Company shall select such Parity Lien Debt to be purchased on a pro rata basis on the basis of the aggregate accreted value or principal amount of tendered Securities and Parity Lien Debt (provided that the selection of such Parity Lien Debt shall be made pursuant to the terms of such Parity Lien Debt) and in such manner as complies with applicable legal requirements and applicable procedures of the Depositary.

(h) The provisions under this Section 4.11 relative to the Company’s obligation to make an offer to repurchase the Securities as a result of a Collateral Sale may be waived or modified at any time with the written consent of the Holders of a majority in principal amount of the Securities.

SECTION 4.12 Collateral and Collateral Sale Covenant Termination. If on any date (a) either (1) both (x) the rating of the Index Debt is (i) BB+ or higher from S&P and Ba2 or higher from Moody’s or (ii) Ba1 or higher from Moody’s and BB or higher S&P and (y) the Leverage Ratio (as such term and all component definitions thereof are defined in the Priority Lien Credit Agreement as in effect on the Issue Date) of the Company (as of the date of its most recent annual or quarterly financial statements filed with the SEC) is less than or equal to 3.00:1.00 or (2) the rating of the Index Debt is (i) BBB- or higher from S&P and Ba1 or higher from Moody’s or (ii) Baa3 or higher from Moody’s and BB+ or higher from S&P (this clause (a), the “Collateral Termination Test”) or (b) upon consummation of a contemplated transaction, immediately after giving effect to such transaction and pro forma for such transaction, any Indebtedness incurred in connection therewith and the use of proceeds therefrom, the Company would be able to satisfy the Collateral Termination Test (including as evidenced by indicative ratings from S&P and Moody’s), on and after such date, in the case of clause (a), or on consummation of such transaction, in the case of clause (b), the Company and its Restricted Subsidiaries will not be subject to the provisions of Section 4.11 and the Liens on the Collateral will be released.

SECTION 5.01 When Company May Merge, etc. The Company shall not consolidate with or merge with or into any Person or sell, convey, lease, transfer or otherwise dispose of all or substantially all of its assets to any Person, unless:

(1) (a) the Company survives such consolidation or merger or (b) the Person formed by such consolidation or into which the Company is merged or that acquires by sale, conveyance, transfer or other disposition, or which leases, all or substantially all of the assets of the Company (a “Successor”) is a corporation, limited liability company, general partnership or limited partnership organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, or Canada or any province thereof, and expressly assumes, by supplemental indenture in a form reasonably satisfactory to the Trustee (and similar documents with respect to the other Note Documents, in each case in a form reasonably satisfactory to the Trustee and Collateral Trustee, as applicable), the due and punctual payment of the principal of, and any premium and interest on, all the Securities and the performance of every other covenant and obligation of the Company under this Indenture and the other Note Documents (including taking such action (or agreeing to take such action) as may be reasonably necessary to cause any property or assets that constitute Collateral owned by or transferred to such Successor to continue to constitute Collateral and to be subject to the Parity Liens in the manner and to the extent required under the Note Documents); provided, that unless the Successor is a corporation, a corporate co-issuer of the Securities shall be added hereto by the execution and delivery of a supplemental indenture by such co-issuer; and

(2) immediately after giving effect to such transaction no Default or Event of Default exists.

In connection with any consolidation, merger, sale, conveyance, lease, transfer or other disposition contemplated by this Section 5.01, the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture, if any, comply with this Indenture.

SECTION 5.02 Successor Substituted. Upon any consolidation, merger, lease, conveyance or transfer in accordance with Section 5.01, the Trustee shall be notified by the Company or the Successor, and the Successor formed by such consolidation or into which the Company is merged or to which such lease, conveyance or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such Successor had been named as the Company herein and thereafter (except in the case of a lease) the predecessor will be relieved of all further obligations and covenants under this Indenture, the Securities and the other Note Documents. The Successor and the Trustee shall enter into a supplemental indenture to evidence the succession and substitution of such Successor and such discharge and release of such predecessor.

SECTION 6.01 Events of Default. An “Event of Default” occurs in respect of the Securities upon:

(1) default by the Company or any Subsidiary Guarantor in the payment of principal of, or any premium on, the Securities when due and payable at maturity;

(2) default by the Company or any Subsidiary Guarantor in the payment of any installment of interest on the Securities when due and payable and continuance of such default for 30 days;

(3) default on any other Indebtedness of the Company or any Subsidiary Guarantor if either (A) such default results in the acceleration of the maturity of any such Indebtedness having a principal amount of $75,000,000 or more individually or, taken together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, in the aggregate, or (B) such default results from the failure to pay when due principal of any such Indebtedness, after giving effect to any applicable grace period (a “Payment Default”), having a principal amount of $75,000,000 or more individually or, taken together with the principal amount of any other Indebtedness under which there has been a Payment Default, in the aggregate; provided that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such default beyond any applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequent acceleration of the Securities shall be rescinded, so long as any such rescission does not conflict with any judgment or decree or applicable provision of law;

(4) default in the performance, or breach of, any covenant or agreement of the Company or any Subsidiary Guarantor in this Indenture and, in each such case, failure to remedy such default within a period of 60 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of the Securities; provided, however, that the Company shall have 90 days after the receipt of such written notice to remedy, or receive a waiver for, any failure to comply with its obligations under this Indenture so long as the Company is attempting to cure such failure as promptly as reasonably practicable;

(5) a Guarantee by a Subsidiary Guarantor shall cease to be in full force and effect (other than a release of a Guarantee in accordance with Section 10.05) or any Subsidiary Guarantor shall deny or disaffirm its obligations with respect thereto;

(6) the Company or any Subsidiary Guarantor pursuant to or within the meaning of any Bankruptcy Law:

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

(E) admits in writing that it generally is unable to pay its debts as the same become due;

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

(A) is for relief (with respect to the petition commencing such case) against the Company or any Subsidiary Guarantor in an involuntary case or proceeding,

(B) appoints a Custodian of the Company or any Subsidiary Guarantor or for all or substantially all of its property,

(C) orders the liquidation of the Company or any Subsidiary Guarantor, and the order or decree remains unstayed and in effect for 60 days; or

(A) except as permitted by the Note Documents, any Note Document establishing the Parity Liens ceases for any reason to be enforceable; provided that it will not be an Event of Default under this clause 8(A) if the sole result of the failure of one or more Note Documents to be fully enforceable is that any Parity Lien purported to be granted under such Note Documents on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $50,000,000, ceases to be an enforceable and perfected Parity Lien; provided further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 90 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period;

(B) except as permitted by the Note Documents, any Parity Lien purported to be granted under any Note Document on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $50,000,000, ceases to be an enforceable and perfected second-priority Lien, subject to the Intercreditor Agreement and Permitted Liens; provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 90 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; or

(C) any Mortgagor, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any obligations of any Mortgagor set forth in or arising under any Note Document establishing Parity Liens.

The term “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.

SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in clauses (6) or (7)) under Section 6.01 occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% of the principal amount of the outstanding Securities may declare the unpaid principal of, and any premium and accrued and unpaid interest on, all the Securities then outstanding to be due and payable, by a notice in writing to the Company (and to the Trustee, if given by Holders), and upon any such declaration such principal, and any premium and accrued and unpaid interest shall become immediately due and payable. If an Event of Default specified in clauses (6) or (7) of Section 6.01 above occurs, all unpaid principal of, and any premium and accrued and unpaid interest on, all Securities then outstanding will become due and payable, without any declaration or other act on the part of the Trustee or any Holder.

The Holders of a majority of the principal amount of the outstanding Securities, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul such declaration of acceleration and its consequences if (1) the Company or any Subsidiary Guarantor has paid or deposited with such Trustee a sum sufficient to pay (A) all overdue installments of interest on all the Securities, (B) the principal of, and any premium and interest on, any Securities that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in the Securities, (C) to the extent that payment of such interest is lawful, interest on the defaulted interest at the rate or rates prescribed therefor in the Securities, and (D) all money paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (2) all Events of Default, other than the non-payment of the principal of, and any premium and interest on, the Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture; and (3) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission will affect any subsequent Event of Default or impair any right consequent thereon.

SECTION 6.03 Other Remedies. Subject to the Intercreditor Agreement, if an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an Event of Default specified under clauses (6) or (7) of Section 6.01 occurs with respect to the Company at a time when the Company is the Paying Agent, the Trustee shall assume the duties of Paying Agent.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the 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. All available remedies are cumulative.

SECTION 6.04 Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of at least a majority of the principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except an Event of Default under clauses (1) and (2) of Section 6.01.

SECTION 6.05 Control by Majority. The Holders of a majority in principal amount of the outstanding Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities, provided that (1) such direction is not in conflict with any rule of law or with this Indenture and (2) the Trustee may take any other action deemed proper by such Trustee that is not inconsistent with such direction.

SECTION 6.06 Limitation on Remedies. No Holder of any of the Securities will have any right to institute any proceeding, judicial or otherwise, to appoint a receiver or trustee or to pursue any remedy under this Indenture, unless:

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

(2) the Holders of not less than 25% of the principal amount of the outstanding Securities have made written request to such Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Indenture,

(3) such Holder or Holders have offered to such Trustee indemnity or security satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request,

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

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority of the principal amount of the outstanding Securities.

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

SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the Holder of any Securities will have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Securities on the due date and to institute suit for the enforcement of any such payment, and such right may not be impaired without the consent of such Holder.

SECTION 6.08 Collection Suit by Trustee. Subject to the Intercreditor Agreement, if an Event of Default in payment of principal or any premium or interest specified in paragraphs (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any Subsidiary Guarantor for the whole amount of principal and any premium and interest then due and remaining unpaid with respect to the Securities, and interest on overdue principal and any premium, and, to the extent lawful, interest on overdue interest, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel.

(a) The 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 Trustee and the Holders allowed in any judicial proceedings relative to the Company, the Subsidiary Guarantors, their creditors or their property and may collect and receive any money or securities or other property payable or deliverable on any such claims and to distribute the same.

(b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10 Priorities. Subject to the Intercreditor Agreement and the Collateral Trust Agreement, if the Trustee collects any money pursuant to this Article Six with respect to the Securities, it shall pay out the money in the following order:

First: to the Trustee, the Collateral Trustee and their agents for amounts due under Section 7.07;

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

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

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

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

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in such exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(1) The Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others and no implied covenants or obligations shall be read into this Indenture against the Trustee.

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be furnished to it, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) This paragraph (c) does not limit the effect of paragraph (b) of this Section 7.01.

(2) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts.

(3) The Trustee shall not be liable to Holders of Securities with respect to action it takes or omits to take in good faith (A) in accordance with a direction received by it from Holders pursuant to Section 6.05, and the Trustee shall be entitled from time to time to request such a direction or (B) in connection with the exercise by the Trustee of any trust or power conferred upon the Trustee under this Indenture.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

(e) The Trustee shall be under no obligation and may refuse to perform any duty or exercise any right, duty or power hereunder unless it receives indemnity or security reasonably satisfactory to it against any loss, liability, claim, damage or expense. No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur liability, financial or otherwise, in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(a) The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper person. The 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, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

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

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

(d) The 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 under this Indenture.

(f) In no event shall the 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 Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

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

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

(i) The Trustee may request that the Company 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.

(j) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution.

(k) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity (including in its capacity as the Collateral Trustee) may become the owner or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04 Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any prospectus, offering or solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication.

SECTION 7.05 Notice of Defaults. If a Default occurs and is continuing and if it is actually known to a Responsible Officer, the Trustee shall mail to each Holder of Securities pursuant to Section 13.02 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice and shall be protected in so withholding if and so long as it determines in good faith that withholding the notice is in the interests of Holders of Securities.

SECTION 7.06 TIA and Listings. The Trustee shall comply with TIA Section 313(b)(2) as if such provision were applicable to this Indenture. The Company shall notify the Trustee in writing when the Securities become listed on any national securities exchange or of any delisting thereof.

SECTION 7.07 Compensation and Indemnity. Each of the Company and the Subsidiary Guarantors, jointly and severally, agrees to pay the Trustee from time to time compensation for its services as shall be agreed upon from time to time in writing between the Company and the Trustee (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company agrees to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and expenses of the Trustee’s agents and counsel.

The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all expenses, disbursements and advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability (including fees and expenses incurred by the Trustee pursuant to the penultimate paragraph of Section 7.08) determined not to have been caused by its own negligence or willful misconduct. Each of the Company and the Subsidiary Guarantors agrees to indemnify the Trustee against any loss, liability, claim, damage or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties hereunder as Trustee, Registrar and/or Paying Agent, if any, including the costs and expenses of enforcing this Indenture against the Company (including with respect to this Section 7.07) and of defending itself against any claim (whether asserted by the Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company of any claim of which a Responsible Officer has received written notice for which it may seek indemnity; however, the failure of the Trustee to promptly notify the Company shall not limit its right to indemnification. The Company shall defend each such claim and the Trustee shall cooperate in the defense. The Trustee may retain separate counsel and the Company shall reimburse the Trustee for the reasonable fees and expenses of such counsel. Neither the Company nor any Subsidiary Guarantor shall pay for any settlement made without its consent (which consent shall not be unreasonably withheld).

Neither the Company nor any Subsidiary Guarantor shall be obligated to reimburse any expense or indemnify against any loss, liability, claim or damage incurred by the Trustee determined to have been caused by the Trustee’s own negligence or willful misconduct. To secure the payment obligations of the Company in this Section, the Trustee shall have a claim

prior to that of the Holders of the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on, or the redemption price of, particular Securities. The Trustee’s right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or Indebtedness of the Company or any Subsidiary Guarantor.

When the Trustee incurs expenses or renders services after the occurrence of any Event of Default specified in clauses (6) or (7) of Section 6.01, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

The benefits of this section shall survive termination of this Indenture and resignation or removal of the Trustee.

SECTION 7.08 Replacement of Trustee. The Trustee may resign by so notifying the Company and the Subsidiary Guarantors. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Subsidiary Guarantors. Immediately after that and upon payment of its charges hereunder, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder of Securities.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of Securities may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Holder of Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Any successor Trustee shall comply with TIA Section 310(a)(5) as if such provision were applicable to this Indenture.

SECTION 7.09 Successor Trustee by Merger, etc. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another corporation or national association, the successor corporation or national association without any further act shall be the successor Trustee; provided that such corporation or national association shall be otherwise eligible and qualified under this Article and shall notify the Company of its successor hereunder.

SECTION 7.10 Eligibility; Disqualification. This Indenture shall always have a Trustee that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Notes shall serve as a Trustee.

SECTION 7.11 Preferential Collection of Claims Against Company . The Trustee shall comply with TIA Section 311(a) as if such provision were applicable to this Indenture, excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein as if such provision were applicable to this Indenture.

SECTION 8.02 Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to exercise its rights pursuant to either Section 8.03 or 8.04 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight.

SECTION 8.03 Legal Defeasance and Discharge. Upon the Company’s exercise under Section 8.02 of the option applicable to this Section 8.03, the Company and each Subsidiary Guarantor shall be deemed to have been discharged from its obligations with respect to all outstanding Securities on the date all conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company and any Subsidiary Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities and any Guarantees thereof, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.06 and the other Sections of this Indenture referred to in clauses (a) and (b) of this Section 8.03, and to have satisfied all their other obligations under such Securities and this Indenture and the other Note Documents (insofar as related to the Securities and this Indenture) (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the

following which shall survive such satisfaction and discharge until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities to receive solely from the trust fund described in Section 8.06, and as more fully set forth in such Section, payments in respect of the principal of, and any premium and interest on, such Securities when such payments are due, (b) the Company’s obligations with respect to such Securities under Sections 2.06, 2.09, 2.10, 2.12 and 4.04, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith (including, but not limited to, Section 7.07) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.03 notwithstanding the prior exercise of its option under Section 8.04.

If the Company exercises its Legal Defeasance option, the Collateral will be released.

SECTION 8.04 Covenant Defeasance. Upon the Company’s exercise under Section 8.02 of the option applicable to this Section 8.04, the Company shall be released from its obligations under the covenants contained in Sections 4.02, 4.03, 4.07, 4.08, 4.09, 4.10 and 4.11, and Article Five and any covenants contained in the Security Documents (insofar as related to the Securities and this Indenture) with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.02 of the option applicable to this Section 8.04, clauses (3) through (8) of Section 6.01 shall not constitute Events of Default with regard to such Securities.

If the Company exercises its Covenant Defeasance option, the Collateral will be released.

SECTION 8.05 Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 8.03 or Section 8.04:

(a) The Company shall irrevocably have deposited or cause to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.10 who shall agree to comply with the provisions of this Article Eight applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of Securities, (a) cash in U.S. Legal Tender in an amount, or (b) U.S. Government Securities which through the scheduled payment of principal and interest in

respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, cash in U.S. Legal Tender in an amount, or (c) a combination thereof, in such amounts, as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (or other qualifying trustee) to pay the principal of, and any premium and interest on, the outstanding Securities on each date on which such principal or any premium or interest is due and payable or on any redemption date established pursuant to the last paragraph of Section 8.06; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government Securities to said payments with respect to the Securities;

(b) In the case of an election under Section 8.03, the Company shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities 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 an election under Section 8.04, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee to the effect that the Holders of the outstanding Securities 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 or, insofar as clauses (6) or (7) of Section 6.01 is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period);

(e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement other than this Indenture (this Indenture being the subject of clause (d) above), or instrument to which the Company is a party or by which the Company is bound;

(f) In the case of any election under Section 8.03 or 8.04, the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit made by the Company pursuant to its election under Section 8.03 or 8.04 was not made by the Company with the intent of preferring the Holders over other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(g) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 8.03 or the Covenant Defeasance under Section 8.04 (as the case may be) have been complied with as contemplated by this Section 8.05.

SECTION 8.06 Deposited Money and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.07, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.06, the “Trustee”) pursuant to Section 8.05 shall be held in trust and applied by the Trustee, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or a Subsidiary Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the Holders of the Securities of all sums due and to become due thereon in respect of principal and any premium and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 8.05 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities.

Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s written request any money or U.S. Government Securities held by it as provided in Section 8.05 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.05(b)), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Before or after the deposit pursuant to Section 8.05(a), the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date pursuant to Article Three.

SECTION 8.07 Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, whether pursuant to this Article Eight or otherwise, in trust for the payment of the principal of, and any premium and interest on, or redemption price on, any Security which has remained unclaimed for two years after such principal and any premium or interest has become due and payable shall be paid to the Company on its written request (unless an abandoned property law designates another Person) or (if then held by the Company) shall be discharged from such trust; and the Holder of such Securities shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

SECTION 8.08 Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Securities in accordance with Section 8.03 or 8.04, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining, or otherwise prohibiting such application, then the Company’s obligations under this Indenture, the Securities and the other Note Documents (insofar as related to this Indenture and the Securities) shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.03 or 8.04 until such time as the Trustee or Paying Agent is permitted to

apply all such money in accordance with this Article Eight; provided, however, that, if the Company makes any payment of principal of, or any premium or interest on, or redemption price on the Securities following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of the Securities to receive such payment from the money held by the Trustee or Paying Agent. In the event the Company’s obligations under this Indenture and the Securities are revived and reinstated pursuant to this Section 8.08, then the obligations of each Subsidiary Guarantor under its Guarantee, if any, and this Indenture that were released pursuant to Section 10.05 as a result of the Company’s exercise of its rights under this Article Eight shall be revived and reinstated as though such release had not occurred.

SECTION 9.01 Without Consent of Holders. The Company, the Subsidiary Guarantors, the Trustee and the Collateral Trustee, if applicable, may amend or supplement this Indenture, the Securities or the other Note Documents without notice to or consent of any Holder:

(a) to cure any ambiguity, omission, defect or inconsistency; provided that such modification shall not adversely affect the Holders in any material respect;

(d) to reflect the addition or release of any Subsidiary Guarantor from its Guarantee, as provided for by this Indenture, or to reflect the addition of any Collateral or the release of Liens on the Collateral, in the manner provided for in this Indenture or the other Note Documents;

(f) to provide for the issuance of Additional Securities in accordance with the limitations set forth in this Indenture;

(h) to make any change that would provide any additional benefit or rights to the Holders or that does not adversely affect the rights of any Holder in any material respect;

(i) to evidence or provide for the acceptance of an appointment by a successor Trustee or Collateral Trustee;

(j) to conform the text of the Note Documents (i) to any provision under the heading “Description of Second Lien Notes” in the Offering Memorandum, to the extent that the Trustee (and Collateral Trustee, if applicable) has received an Officers’ Certificate stating that such text constitutes an unintended conflict with, or is inconsistent with, the description of the

corresponding provision in such “Description of Second Lien Notes” or (b) as may be necessary or advisable to preserve and confirm the relative priorities of the Secured Debt Documents as such priorities are contemplated by and set forth in the Intercreditor Agreement, as set forth in an Officers’ Certificate delivered to the Trustee (and Collateral Trustee, if applicable);

(k) to make, complete or confirm any grant of Collateral permitted or required by the Note Documents;

(l) to release or subordinate Liens on Collateral in accordance with the Note Documents or to confirm and evidence such release or subordination, or the termination or discharge of any Lien with respect to or securing the Securities or the Guarantee, in accordance with the Note Documents; or

(m) with respect to the Note Documents, as provided in the Intercreditor Agreement and the Collateral Trust Agreement.

In addition, the Intercreditor Agreement and the Collateral Trust Agreement may be amended in accordance with their terms and without the consent of any Holder or the Trustee with the consent of the parties thereto or otherwise in accordance with their terms, including to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any authorized agent thereof or trustee therefor) holding such Indebtedness thereto and to establish that the Liens on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding, in each case to the extent permitted by the Secured Debt Documents.

Upon the written request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and of each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee and the Collateral Trustee, if applicable, shall join with the Company and the Subsidiary Guarantors in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained.

SECTION 9.02 With Consent of Holders. Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors, the Trustee and the Collateral Trustee, if applicable, may amend or supplement this Indenture or the Securities with the consent (including consents obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities) of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding.

For purposes of this Indenture, the consent of the Holder of a Global Security shall be deemed to include any consent delivered by any member of, or participant in, the Depositary or such other depositary institution hereinafter appointed by the Company by electronic means in accordance with the Automated Tender Offer Procedures system or other customary procedures of, and pursuant to authorization by, such entity.

Upon the written request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee and the Collateral Trustee, if applicable, of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel and Officers’ Certificate described in Section 9.06, the Trustee and the Collateral Trustee, if applicable, shall join with the Company and the Subsidiary Guarantors in the execution of such supplemental indenture.

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

The Holders of a majority in aggregate principal amount of the outstanding Securities may waive compliance in a particular instance by the Company or the Subsidiary Guarantors with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities). However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section may not:

(1) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities;

(2) reduce the rate or change the time for payment of interest, including default interest, if any, on the Securities;

(3) reduce the principal amount of any Security or change the Maturity Date of the Securities;

(8) impair the right of Holders of Securities to receive payment of the principal of and interest on Securities on the respective due dates therefor and to institute suit for the enforcement of any such payment; or

(9) make any change in Sections 6.04 or 6.07 or in this sentence of this Section 9.02.

In addition, the consent of Holders representing at least 66.67% of the outstanding Securities (including consents obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities) will be required to release the Liens for the benefit of the Holders on all or substantially all of the Collateral, other than in accordance with the Note Documents.

SECTION 9.04 Revocation and Effect of Consents. A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives written notice of revocation before a date and time therefor identified by the Company in a notice furnished to such Holder in accordance with the terms of this Indenture or, if no such date and time shall be identified, the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If the Company elects to fix a record date for such purpose, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.08, or (ii) such other date as the Company shall designate. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consent from the Holders of the principal amount of Securities required hereunder for such amendment, supplement or waiver to be effective also shall have been given and not revoked within such 90-day period.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any of clauses (1) through (9) of Section 9.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

SECTION 9.05 Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make appropriate notation or issue a new Security shall not affect the validity of any such amendment, supplement or waiver.

SECTION 9.06 Trustee Protected. The Trustee and the Collateral Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article Nine if the amendment, supplement or waiver does not adversely affect the rights of the Trustee or the Collateral Trustee, as applicable. If it does adversely affect the rights of the Trustee or the Collateral Trustee, the Trustee or the Collateral Trustee, as applicable, may but need not sign it. In signing such amendment, supplement or waiver the Trustee and the Collateral Trustee shall be provided with, and (subject to Article Seven) shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate of the Company complying with the requirements of Section 13.05 and stating that such amendment, supplement or waiver is authorized or permitted by and complies with this Indenture.

SECTION 10.02 Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees, as principal obligor and not only as surety (such guarantee to be referred to herein, individually and collectively, as the “Guarantee”), to each Holder the due and punctual payment of the principal of, and any premium and interest on, the Securities and all other amounts due and payable under this Indenture and the Securities by the Company whether at Maturity Date or otherwise, including, without limitation, interest on the overdue principal of, and any premium and interest on, the Securities, to the extent lawful, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.06.

Failing payment when due of any amount so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and in this Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Subsidiary Guarantor, any amount paid by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor agrees it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between each

Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Guarantee.

(a) Subject to paragraph (b) of this Section 10.03, no Subsidiary Guarantor (other than a Subsidiary Guarantor whose Guarantee is to be released in accordance with this Indenture) may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person unless (i) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) ( a “Successor Guarantor”) assumes all the obligations of such Subsidiary Guarantor under this Indenture and the other Note Documents (and takes such action (or agrees to take such action) as may be reasonably necessary to cause any property or assets that constitute Collateral owned by or transferred to such Successor Guarantor to continue to constitute Collateral and to be subject to the Parity Liens in the manner and to the extent required under the Note Documents) pursuant to a supplemental indenture (and similar documents with respect to the other Note Documents), in each case, in a form reasonably satisfactory to the Trustee and Collateral Trustee and (ii) immediately after such transaction, no Default or Event of Default exists. In connection with any consolidation or merger contemplated by this Section 10.03, the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture, if any, comply with this Indenture. This Section 10.03(a) is not applicable to a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor.

(b) In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, in any case by way of merger, consolidation or otherwise, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Subsidiary Guarantor) or the Person acquiring the assets (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be automatically released and relieved of any obligations under its Guarantee and, if such Subsidiary Guarantor is a Mortgagor, the Lien on such Mortgagor’s Collateral securing the Parity Lien Obligations (including such Mortgagor’s Guarantee) will be released.

(a) The Company shall cause each Person that becomes a domestic Subsidiary after the Issue Date and that guarantees any other Indebtedness of the Company or a Subsidiary Guarantor in excess of a De Minimis Guaranteed Amount to execute and deliver a supplemental indenture pursuant to which such Subsidiary shall guarantee the payment of such Securities pursuant to the terms hereof within 60 days after the later of (i) the date that such Person

becomes a domestic Subsidiary and (ii) the date that such Person guarantees such other Indebtedness; provided that no guarantee shall be required if the Subsidiary merges into the Company or merges into an existing Subsidiary Guarantor and the surviving entity remains a Subsidiary Guarantor.

(b) Any Person that was not a Subsidiary Guarantor on the date of this Indenture may become a Subsidiary Guarantor by executing and delivering to the Trustee (i) a supplemental indenture in form and substance satisfactory to the Trustee, which subjects such Person to the provisions of this Indenture as a Subsidiary Guarantor and (ii) an Opinion of Counsel and Officers’ Certificate to the effect that such supplemental indenture has been duly authorized and executed by such Person and constitutes the legal, valid and binding obligation of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion and provided that no opinion need be rendered concerning the enforceability of the Guarantee) and complying with the requirements of Section 13.05.

SECTION 10.05 Release of a Subsidiary Guarantor. Upon (i) the sale or disposition of all the Capital Stock of a Subsidiary Guarantor (or all or substantially all of its assets), in any case whether by way of merger, consolidation or otherwise or (ii) subject, in the case of a Mortgagor, to satisfaction of the requirements set forth in Section 4.01(a)(i) of the Intercreditor Agreement, the cessation by a Subsidiary Guarantor to guarantee any other Indebtedness of the Company or any other Subsidiary Guarantor other than a De Minimis Guaranteed Amount, in each case which is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 10.03, such Subsidiary Guarantor shall be automatically released from all of its Guarantee and related obligations in this Indenture without any further action by the Trustee, the Company or such Subsidiary Guarantor and, if such Subsidiary Guarantor is a Mortgagor, the Lien on such Mortgagor’s Collateral securing the Parity Lien Obligations (including such Mortgagor’s Guarantee) shall be released. Subject to Section 8.08, upon the Company’s election, in compliance with the conditions set forth in Article Eight hereof, to exercise its rights pursuant to either Section 8.03 or 8.04 with respect to all outstanding Securities, each Subsidiary Guarantor shall be automatically released from all of its Guarantee and related obligations in this Indenture without any further action by the Trustee, the Collateral Trustee, the Company or any Subsidiary Guarantor. The Trustee and the Collateral Trustee, as applicable, shall deliver an appropriate instrument evidencing any such release upon receipt of a written request by the Company accompanied by an Officers’ Certificate. Any Subsidiary Guarantor not so released remains liable for the full amount of principal of and interest on the Securities as provided in this Article Ten.

SECTION 10.06 Limitation of Subsidiary Guarantor’s Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal, state or foreign law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of

such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.07, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, state or foreign law. This Section 10.06 is for the benefit of the creditors of each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor pursuant to Credit Facilities shall be deemed to have been incurred prior to the incurrence by such Subsidiary Guarantor of its liability under the Guarantee.

SECTION 10.07 Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company’s obligations with respect to the Securities or any other Subsidiary Guarantor’s obligations with respect to the Guarantee.

SECTION 10.08 Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

(a) The due and punctual payment of the Obligations on the Securities and the Obligations of the Subsidiary Guarantors under the Guarantees, when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest (to the extent permitted by law), on the Securities, the Guarantees and performance and payment of all other obligations of the Company and the Subsidiary Guarantors to the Holders or the Trustee and/or the Collateral Trustee under the Note Documents, according to the terms hereunder or thereunder (collectively, the “Notes Obligations”), are secured as provided in the Security Documents. The Company and each of the Subsidiary Guarantors consent and agree to be bound by the terms of the Security Documents to which they are parties, as the same may be in effect from time to time, and agree to perform their obligations thereunder in accordance therewith. The Company and the Subsidiary Guarantors hereby agree that the Collateral Trustee shall hold the Collateral on behalf of and for the benefit of all of the Holders and the other holders of Parity Lien Obligations.

(b) Each Holder of Securities, by its acceptance thereof and of the Guarantees, consents and agrees to the terms of the Intercreditor Agreement, the Collateral Trust Agreement and the Security Documents (including, without limitation, the provisions providing for

foreclosure and release of Collateral and amendments to the Security Documents) as the same may be in effect or may be amended from time to time in accordance with their terms, and authorizes and appoints Deutsche Bank Trust Company Americas as the Trustee and as the Collateral Trustee. The Trustee hereby authorizes and appoints Deutsche Bank Trust Company Americas as Collateral Trustee, and each Holder of Securities and the Trustee direct the Collateral Trustee to enter into the Security Documents (including any amendments thereto contemplated by Section 7.1 of the Collateral Trust Agreement and any security documents to secure additional Parity Lien Debt in accordance with Section 5.3 of the Collateral Trust Agreement, all as more particularly described in the Collateral Trust Agreement) and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof, including, the limitations on duties of the Collateral Trustee provided in Section 5.12 of the Collateral Trust Agreement. The Trustee, the Collateral Trustee and each Holder of Securities, by accepting the Securities and the Guarantees of the Subsidiary Guarantors, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be held, subject to the Intercreditor Agreement, for the benefit of all the holders of Parity Lien Obligations, the Collateral Trustee and the Trustee, and the Lien of this Indenture and the Security Documents is subject to and qualified and limited in all respects by the Intercreditor Agreement, the Collateral Trust Agreement, the Security Documents and actions that may be taken thereunder.

(a) Within 60 days of the Issue Date, the Company shall, or shall cause the applicable Subsidiary Guarantor to, (i) execute and deliver to the Collateral Trustee, as mortgagee or beneficiary, as applicable, such Mortgages, together with satisfactory evidence of the completion (or satisfactory arrangements for the completion) of all recordings and filings of such Mortgages in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith) as may be necessary to create a valid, perfected second-priority Lien (subject to the Intercreditor Agreement), against the Oil and Gas Properties and related assets of the Company and the Subsidiary Guarantors that are subject to Liens securing the Priority Lien Obligations on the Issue Date and (ii) on the date that each such Mortgage is so filed or recorded, cause its counsel for the jurisdiction in which the relevant Oil and Gas Properties and related assets are located to execute and deliver to the Collateral Trustee a favorable Opinion of Counsel with respect thereto in form and substance reasonably satisfactory to the Collateral Trustee.

(b) Any Security Documents entered into after the Issue Date shall be substantially in the form of the corresponding security document securing the Priority Liens Obligations, or to the extent there is no such corresponding security document, the corresponding security documents securing the Priority Lien Obligations in place on the Issue Date, in each case, with such changes as are reasonably necessary to reflect the terms of the Intercreditor Agreement and with such deletions or modifications of representations, warranties and covenants as are customary with respect to security documents establishing Liens securing publicly traded debt securities, all as certified to the Collateral Trustee pursuant to an Officers’ Certificate of the Company.

(a) The Company and each of the Subsidiary Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of Parity Lien Obligations, duly created Liens upon the Collateral (including any property or assets constituting Collateral that are acquired or otherwise become, or are required by any Parity Lien Document to become, Collateral after the Issue Date), in each case, as contemplated by, and, to the extent required to be perfected, perfected, and enforceable Liens, with the Lien priority required under, the Parity Lien Documents, and in connection with any merger or consolidation of any Mortgagor, the property and assets of the Person which is consolidated or merged with or into any Mortgagor, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property and the Company or such other Mortgagor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Parity Liens, in the manner and to the extent required under the Parity Lien Documents.

(b) Upon the reasonable request of the Collateral Trustee or any Parity Lien Representative at any time and from time to time, each of the Company and the other Mortgagors shall promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Parity Lien Documents for the benefit of the holders of Parity Lien Obligations; provided, that no such Security Document, instrument or other document shall contain provisions that are materially more burdensome upon the Mortgagors than the Parity Lien Documents executed and delivered (or required to be executed and delivered promptly after the Issue Date, including pursuant to Section 11.02) by the Mortgagors in connection with the issuance of the Securities on the Issue Date. Notwithstanding anything to the contrary in this Indenture or the Security Documents, and subject to the Intercreditor Agreement, the Company and the Subsidiary Guarantors shall not be required to take any action to perfect a security interest in any Collateral other than (i) to file financing or continuation statements under the Uniform Commercial Code (or similar laws) in effect in any jurisdiction with respect to the security interests created under the Security Documents and (ii) recordings and filings of Mortgages, as described in Section 11.02(a).

(c) In addition, from and after the Issue Date, if the Company or any Subsidiary Guarantor acquires any property or asset that constitutes collateral for the Priority Lien Debt or Junior Lien Debt, and any Priority Lien Document or Junior Lien Document, as applicable, requires any supplemental security document for such collateral or other actions to achieve a perfected Lien on such collateral, the Company shall, or shall cause the applicable Subsidiary Guarantor to, promptly (but in any event no later than the date that is 60 days after which such supplemental security documents are executed and delivered (or other action taken) under such Priority Lien Documents or Junior Lien Documents, as applicable), to the extent permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security Documents (or amendments thereto) in such form as shall be necessary in the Collateral Trustee’s reasonable discretion to grant the Collateral Trustee a perfected second-priority Lien

on such Collateral or take such other actions in favor of the Collateral Trustee as shall be reasonably necessary to grant a valid and enforceable perfected second-priority Lien on such Collateral to the Collateral Trustee, for the benefit of the Holders and holders of any other Parity Lien Obligations, subject to the terms of this Indenture, the Intercreditor Agreement and the other Note Documents. Additionally, subject to this Indenture, the Intercreditor Agreement and the other Note Documents, if the Company or any Subsidiary Guarantor creates any additional Lien upon any assets or property that is required to become Collateral, or takes any additional actions to perfect any existing Lien on Collateral, in each case for the benefit of the holders of the Priority Lien Debt or the holders of Junior Lien Debt, after the Issue Date, the Company or such Subsidiary Guarantor, as applicable, shall, to the extent permitted by applicable law, within 60 days after such Lien is granted or other action taken, grant a valid and enforceable perfected second-priority Lien upon such property or asset, or take such additional perfection actions, as applicable, for the benefit of the Holders and obtain all related deliverables as those delivered to the Priority Lien Representative or Junior Lien Agent, as applicable, in each case as security for the Notes Obligations. Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Agent, or of agents or bailees of the Priority Lien Agent, the perfection actions and related deliverables described in this Section 11.03(c) shall not be required.

From and after the Issue Date, if the Company or any Subsidiary Guarantor grants a Lien (an “Additional Collateral Lien”) on any property or assets, other than Excluded Property, to secure Indebtedness under a Credit Facility that does not constitute Priority Lien Debt, then the Company shall, or shall cause the applicable Subsidiary Guarantor to, promptly (but in any event no later than the date that is 60 days thereafter), to the extent permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security Documents in such form as shall be necessary in the Collateral Trustee’s reasonable discretion to grant the Collateral Trustee a valid and enforceable Lien on such property or assets perfected on a second lien basis to such Additional Collateral Lien to secure the Parity Lien Obligations, subject to the terms of an intercreditor arrangement substantially in the form of the Intercreditor Agreement, as it relates to the Priority Lien Debt and the Parity Lien Debt, including with respect to releases of such Liens. Notwithstanding anything to the contrary contained herein, any such property or assets that become subject to a Lien to secure the Parity Lien Obligations as provided in this Section 11.03(c) will not constitute “Collateral” for purposes of the Intercreditor Agreement. No Credit Facility shall be permitted to be secured as described in this second paragraph of this Section 11.03(c) unless the Priority Lien Agent shall have consented to such property and assets not constituting “Collateral” for purposes of the Intercreditor Agreement.

(d) The Company will deliver to the Trustee copies of all documents delivered to the Collateral Trustee pursuant to the Security Documents.

(e) Each applicable Mortgagor will cause to be delivered to the Collateral Trustee an Opinion of Counsel to the effect that the Collateral Trustee has a valid and perfected Lien with respect to each real property subject to a Mortgage only in the circumstances required by the Collateral Trust Agreement.

(f) In acting hereunder and under the other Note Documents, the Holders, the Company and the Subsidiary Guarantors agree that the Collateral Trustee shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits provided to the Trustee hereunder as if such were provided to the Collateral Trustee.

SECTION 11.04 Intercreditor Agreement. This Article 11 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. The Company and each Subsidiary Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each Holder of Securities, by its acceptance of the Securities (a) consents to the subordination of Liens provided for in the Intercreditor Agreement, (b) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes and instructs the Collateral Trustee on behalf of each Holder to enter into the Intercreditor Agreement as Original Second Lien Collateral Trustee (as defined in the Intercreditor Agreement) on behalf of such Holders as Second Lien Secured Parties (as defined in the Intercreditor Agreement). In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding, in each case, where the incurrence of such secured Indebtedness is permitted by this Indenture. The foregoing provisions are intended as an inducement to the lenders under the Priority Lien Credit Agreement to extend credit to the Company and certain of the Subsidiaries, and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

SECTION 11.05 Collateral Trust Agreement. This Article 11 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Collateral Trust Agreement. The Company and each Subsidiary Guarantor consents to, and agrees to be bound by, the terms of the Collateral Trust Agreement and to perform its obligations thereunder in accordance with the terms therewith. Each Holder of Securities, by its acceptance of the Securities (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Trust Agreement and (b) authorizes and instructs the Collateral Trustee on behalf of the Holders and each other holder of Parity Lien Obligations to enter into the Collateral Trust Agreement as Collateral Trustee on behalf of the Holders and the other holders of Parity Lien Obligations.

SECTION 11.06 Release of Liens in Respect of Securities. The Collateral Trustee’s Parity Liens upon the Collateral will no longer secure the Securities outstanding under this Indenture or any other Notes Obligations, and the right of the Holders to the benefits and proceeds of the Collateral Trustee’s Parity Liens on the Collateral will terminate and be discharged:

(a) upon satisfaction and discharge of this Indenture in accordance with Article 12 hereof;

(b) upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof;

(c) upon payment in full in cash and discharge of all Securities outstanding under this Indenture and all other Notes Obligations that are outstanding, due and payable under this Indenture and the other Note Documents at the time the Securities are paid in full in cash and discharged (other than contingent indemnity obligations for which no claim has been made);

(d) as to any Collateral of a Mortgagor that is sold, transferred or otherwise disposed of by a Mortgagor to a Person that is not (either before or after such sale, transfer or disposition) the Company or a Subsidiary of the Company in a transaction or other circumstance that does not violate Section 4.11 (other than the obligation to apply proceeds of such Collateral Sale as provided in such section) and is permitted by all of the other Note Documents (including, for the avoidance of doubt, Section 4.01(a)(i) of the Intercreditor Agreement), at the time of such sale, transfer or other disposition or to the extent of the interest sold, transferred or otherwise disposed of; provided that the Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 5.01;

(e) in whole or in part, with the consent of the Holders of the requisite percentage of aggregate principal amount of Securities in accordance with Section 9.02 hereof;

(f) with respect to the assets of any Subsidiary Guarantor that is a Mortgagor, at the time that such Subsidiary Guarantor is released from its Guarantee in accordance with Section 10.05, subject to satisfaction of the requirements set forth in Section 4.01(a)(i) of the Intercreditor Agreement;

(h) if and to the extent required by Section 4.1(a) of the Collateral Trust Agreement or Section 4.01(a) of the Intercreditor Agreement.

Upon receipt of an Officers’ Certificate and Opinion of Counsel, the Collateral Trustee shall execute, deliver or acknowledge any necessary or proper instruments of termination, satisfaction or release prepared by the Company of any Collateral permitted to be released pursuant to this Section 11.06.

(a) The Collateral Trustee will hold (directly or through co-trustees or agents) and, subject to the terms of the Intercreditor Agreement, will be entitled to enforce all Liens on the Collateral created by the Security Documents.

(b) Except as provided in the Collateral Trust Agreement or as directed by an Act of Parity Lien Debtholders in accordance with the Collateral Trust Agreement, the Collateral Trustee will not be obligated:

(3) to take any other action whatsoever with regard to any or all of the Security Documents, the Liens created thereby or the Collateral.

(c) By accepting a Security, each Holder is deemed to authorize the Collateral Trustee to release or subordinate any Collateral that is permitted to be sold, reclassified or released or be subject to a Priority Lien pursuant to the terms of this Indenture and the Security Documents. By accepting a Security, each Holder is deemed to authorize the Collateral Trustee to execute and deliver to the Company, at the Company’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Company in connection with any sale, reclassification or other disposition of Collateral to the extent such sale, reclassification or other disposition, and such release of Liens, is permitted by the terms of this Indenture and the Security Documents.

(d) Neither the Trustee nor the Collateral Trustee shall be responsible for (i) perfecting, maintaining, monitoring, preserving or protecting the security interest or Lien granted under the Security Documents or any agreement or instrument contemplated hereby or thereby, (ii) the filing, re-filing, recording, re-recording or continuing of any document, financing statement, Mortgage, assignment, notice, instrument of further assurance or other instrument in any public office at any time or times or (iii) providing, maintaining, monitoring or preserving insurance on or the payment of taxes with respect to the Collateral. The actions described in clauses (i) through (iii) shall be the sole responsibility of the Company and the Subsidiary Guarantors.

SECTION 12.01 Satisfaction and Discharge of Indenture. This Indenture and the other Note Documents (insofar as related to the Indenture and the Securities) shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and the other Note Documents (insofar as related to the Indenture and the Securities), when:

(1) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.10, and (ii) Securities for whose payment money has theretofore been, as provided in Section 2.07, deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 8.07) have been delivered to the Trustee for cancellation; or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company in the case of (A), (B) or (C) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for this purpose an amount of money in U.S. Legal Tender sufficient to pay and discharge the entire indebtedness on Securities not theretofore delivered to the Trustee for cancellation, for principal of, and any premium and interest thereon, to the Maturity Date or applicable redemption date, as the case may be in accordance with the terms of this Indenture and the Securities;

Notwithstanding the satisfaction and discharge of this Indenture with respect to Securities, (i) the obligations of the Company to the Trustee under Section 7.07 and the right of the Trustee to resign under Section 7.08 shall survive, (ii) the obligations of the Company in Sections 2.06, 2.07, 2.08, 2.09, 2.10 and 2.11 and in Article 8 and this Article 12 shall survive until the Securities have been repaid in full, and (iii) if money shall have been deposited with the Trustee pursuant to clause (2) of subsection (a) of this Section, the obligations of the Company and/or the Trustee under Sections 2.08, 4.04, 7.01(f), 8.07 and 12.02 shall survive such satisfaction and discharge.

SECTION 12.02 Application of Trust Money. Subject to the provisions of Section 8.07, all money deposited with the Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee.

SECTION 13.02 Notices. Any notice or communication to the Company, any Subsidiary Guarantor, the Trustee, the Collateral Trustee or any Agent shall be sufficiently given if in writing in English and delivered in person or mailed by certified or registered mail (return receipt requested), e-mail in PDF format, facsimile, telecopier or overnight courier guaranteeing next day delivery, addressed as follows:

The Company, any Subsidiary Guarantor, the Trustee, the Collateral Trustee or any Agent by notice to the other may designate additional or different addresses for subsequent notices or communications.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail in PDF format, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee e-mail in PDF format or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its reasonable discretion elects to act upon such instructions, the Trustee’s reasonable understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reasonable reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction.

For the purposes of this Appendix the following terms shall have the meanings indicated below:

“Transfer Restricted Securities” means Securities that bear or are required to bear the legend set forth in Section 2.3(d)(i) hereof.

“Unrestricted Securities” means any Securities that are not Transfer Restricted Securities.

(a) Form and Dating. Securities offered and sold to QIBs (“Rule 144A Global Securities”) shall be issued initially in the form of one or more permanent Global Securities in definitive, fully registered form, and Securities offered and sold in reliance on Regulation S under the Securities Act (“Regulation S”), shall be issued initially in the form of one or more temporary Global Securities in fully registered form (“Temporary Regulation S Global Securities”), in each case, without interest coupons and with the Global Securities legend, Restricted Securities legend and the OID Legend set forth in Section 2.3 (each security, unless and until becoming an Unrestricted Security in accordance with Section 2.3(d)(ii) below, a “Restricted Global Security”), which shall be deposited on behalf of the holders of the Securities represented thereby with the Trustee, as custodian for the Depositary (or with such other custodian as the Depositary may direct), and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the Depositary.

The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary and (b) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the Trustee as custodian for the Depositary. If such Global Securities are Restricted Global Securities, then separate Global Securities shall be issued to represent Rule 144A Global Securities and Regulation S Global Securities so long as required by law or the Depositary.

Except as set forth in this Section 2.1(b), beneficial interests in the Temporary Regulation S Global Security will not be exchangeable for interests in the Rule 144A Global Security, a permanent global security (the “Permanent Regulation S Global Security” and, together with the Temporary Regulation S Global Security, the “Regulation S Global Security”) or any other Security prior to the expiration of the period through and including the 40th day after the later of the commencement of the offering of any Securities and the closing of such offering (such period, the “Restricted Period”) and then, after the expiration of the Restricted Period, may be exchanged for interests in a Rule 144A Global Security or the Permanent Regulation S Global Security only upon certification in form reasonably satisfactory to the Company and the Trustee that beneficial ownership interests in such Temporary Regulation S Global Security are owned either by non-U.S. persons or U.S. persons who purchased such interests in a transaction that did not require registration under the Securities Act.

Prior to the expiration of the Restricted Period, beneficial interests in the Temporary Regulation S Global Security may be exchanged for beneficial interests in the Rule 144A Global Security only if (i) such exchange occurs in connection with a transfer of the Securities pursuant to Rule 144A under the Securities Act (“Rule 144A”), (ii) the transferor first delivers to the Trustee a written certificate (in the form provided in Exhibit 1 hereto) to the effect that the beneficial interest in the Temporary Regulation S Global Security is being transferred to a Person who the transferor reasonably believes to be a QIB and is purchasing for its own account or the account of a QIB, in each case in a transaction meeting the requirements of Rule 144A, and (iii) the transfer is in accordance with all applicable securities laws of the states of the United States and other jurisdictions. After the expiration of the Restricted Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Security representing Regulation S Global Securities.

Beneficial interests in a Rule 144A Global Security may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Global Security, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in Exhibit 1 hereto) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available).

The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as provided herein and in the Indenture.

(c) Certificated Securities. Except as provided in Section 2.13(c) of the Indenture, owners of beneficial interests in Restricted Global Securities shall not be entitled to receive Certificated Securities. Certificated Securities shall be exchangeable for beneficial interests in Global Securities only as provided in Section 2.13(c) of the Indenture and Section 2.3.

(a) Transfer and Exchange of Global Securities. The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Security shall deliver to the Registrar a written order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the Global Security. The Registrar shall, in accordance with such instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer the beneficial interest in the Global Security being transferred.

(i) Notwithstanding any other provisions of this Appendix, a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(ii) In the event that a Restricted Global Security is exchanged for Certificated Securities pursuant to Section 2.4(a) hereof, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Securities intended to ensure that such transfers comply with Rule 144A or Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(b) Transfer and Exchange of Certificated Securities. When Certificated Securities are presented to the Registrar with a request (x) to register the transfer of such Certificated Securities or (y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Securities surrendered for transfer or exchange:

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and

(ii) if such Certificated Securities are required to bear a Restricted Securities legend, they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(c) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Certificated Securities are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or

(B) if such Certificated Securities are being transferred to the Company, a Subsidiary Guarantor or any Subsidiary thereof a certification to that effect; or

(C) if such Certificated Securities are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (I) a certification to that effect (in the form set forth on the reverse of the Security) and (II) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.3(d).

(c) Restrictions on Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated Security may not be exchanged for a beneficial interest in a Rule 144A Global Security or a Permanent Regulation S Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

(i) certification, in the form set forth on the reverse of the Security, that such Certificated Security is either (A) being transferred to a QIB in accordance with Rule 144A, or (B) being transferred after expiration of the Restricted Period by a Person who initially purchased such Security in reliance on Regulation S to a buyer who elects to hold its interest in such Security in the form of a beneficial interest in the Permanent Regulation S Global Security; and

(ii) written instructions directing the Trustee to make, or to direct the Securities custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (c)(i)(A)) or Permanent Regulation S Global Security (in the case of a transfer pursuant to clause (c)(i)(B)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global Security or Permanent Regulation S Global Security, as applicable, such instructions to contain information regarding the Depositary account to be credited with such increase,

then the Trustee shall cancel such Certificated Security and cause, or direct the Securities custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Securities custodian, the aggregate principal amount of Securities represented by the Rule 144A Global Security or Permanent Regulation S Global Security, as

applicable, to be increased by the aggregate principal amount of the Certificated Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security or Permanent Regulation S Global Security, as applicable, equal to the principal amount of the Certificated Security so canceled. If no Rule 144A Global Securities or Permanent Regulation S Global Securities, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate of the Company, a new Rule 144A Global Security or Permanent Regulation S Global Security, as applicable, in the appropriate principal amount.

(i) Except as permitted by the following paragraph (ii) and (iii), each Security certificate evidencing the Restricted Global Securities (and all Securities issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form:

THIS SECURITY HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION.

Each Temporary Regulation S Global Security shall also bear the following legend:

THE RIGHTS ATTACHING TO THIS TEMPORARY REGULATION S GLOBAL SECURITY, AND THE CONDITIONS AND PROCEDURES GOVERNING (I) THE EXCHANGE OF BENEFICIAL INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL SECURITY FOR INTERESTS IN THE PERMANENT REGULATION S GLOBAL SECURITY OR RULE 144A GLOBAL SECURITY AND (II) THE TRANSFER OF INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL SECURITY, ARE AS SPECIFIED IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

(ii) The Company, acting in its discretion, may remove the Restricted Securities legend set forth in paragraph (i) above from any Transfer Restricted Security at any time on or after the Resale Restriction Termination Date applicable to such Transfer Restricted Security. Without limiting the generality of the preceding sentence, the Company may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Security, an Unrestricted Security without such legend, registered to the same Holder and in an equal principal amount, and upon receipt by the Trustee of a Company Order stating that the Resale Restriction Termination Date applicable to such Transfer Restricted Security has occurred and requesting the authentication and delivery of an Unrestricted Security in exchange therefor given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Security to the Depositary or pursuant to such Depositary’s instructions or hold such Security as custodian for the Depositary and shall request the Depositary to, or, if the Trustee is custodian of such Transfer Restricted Security, shall itself, surrender such Transfer Restricted Security in exchange for such Unrestricted Security without such legend and thereupon cancel such Transfer Restricted Security so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date has occurred with respect to any Securities evidenced by a Transfer Restricted Security or delivering any order pursuant to this Section 2.3(d)(ii) with respect to such Securities, (i) only those Securities which a Principal Officer of the Company actually knows (after reasonable inquiry) to be or to have been owned by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the treasurer or the principal accounting officer of the Company.

For purposes of this Section 2.3(d)(ii), all provisions relating to the removal of the legend set forth in paragraph (i) above shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Securities evidenced by a Transfer Restricted Security, to such portion of the Securities so evidenced as to which the Resale Restriction Termination Date has occurred.

Each holder of any Securities evidenced by any Restricted Global Security, by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s behalf, as the Depositary or the Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depositary or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the legend set forth in Section 2.3(d)(i) (including by means of the exchange of all or the portion of such Restricted Global Security evidencing such Security for a certificate evidencing such Security that does not bear such legend) at any time after the Resale Restriction Termination Date.

(iii) Upon any sale or transfer of a Transfer Restricted Security that is a Certificated Security pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a Certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that, and if the Company or the Trustee so request, delivers an opinion of counsel to the effect that, such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security).

(iv) Each Security certificate evidencing the Restricted Global Securities (and all Securities issued in exchange therefor or in substitution thereof), unless not required in the Company’s reasonable determination, shall bear a legend in substantially the following form (the “OID Legend”).

UPON REQUEST, THE COMPANY WILL PROMPTLY MAKE AVAILABLE TO A HOLDER OF THIS SECURITY THE FOLLOWING INFORMATION: (1) THE ISSUE PRICE AND ISSUE DATE OF THIS SECURITY, (2) THE AMOUNT OF OID, (3) THE YIELD TO MATURITY OF THIS SECURITY, AND (4) ANY OTHER INFORMATION REQUIRED TO BE MADE AVAILABLE BY U.S. TREASURY REGULATIONS. HOLDERS SHOULD CONTACT THE CHIEF FINANCIAL OFFICER AT 6100 NORTH WESTERN AVENUE, OKLAHOMA CITY, OKLAHOMA 73118.

(e) Restrictions on Transfer of Temporary Regulation S Global Securities. During the Restricted Period, beneficial ownership interests in Temporary Regulation S Global Securities may only be sold, pledged or transferred in accordance with the applicable procedures of the Depositary and only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange for an interest in a Permanent Regulation S Global Security) or (iii) pursuant to an effective registration statement under the Securities Act, in each case, in accordance with any applicable securities laws of any state of the United States.

(f) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been exchanged for Certificated Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Company for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the custodian for such Global Security) with respect to such Global Security, by the Trustee or the custodian, to reflect such reduction.

(g) No Obligation of the Trustee. The 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 Security (including any transfers between or among Depositary participants, members or beneficial owners in any Global Security) 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.

(a) A Global Security deposited with the Depository or with the Trustee as custodian for the Depository pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only in the circumstances described in Section 2.13(c) of this Indenture and only if such transfer complies with Section 2.3 hereof.

Any portion of a Global Security transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered only in denominations equal to $2,000 or an integral multiple of $1,000 in excess thereof, and registered in such names as the Depository shall direct. Any Certificated Security delivered in exchange for an interest in a Global Security shall, except as otherwise provided by Section 2.3, bear the Restricted Securities legend, Certificated Securities legend and, if applicable, the OID Legend set forth in Exhibit 1 hereto.

Chesapeake Energy Corporation, an Oklahoma corporation, promises to pay to , or registered assigns, the principal sum of Dollars [(as may be increased or decreased as set forth on the Schedule of Increases or Decreases in Global Security attached hereto)]² on December 15, 2022.

Additional provisions of this Security are set forth on the other side of this Security.

Chesapeake Energy Corporation, an Oklahoma corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the fixed rate per annum shown above. The Company shall pay interest semiannually on June 15 and December 15 of each year. The first interest payment date shall be June 15, 2016. Interest on the Security shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 23, 2015. Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the June 1 or December 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Depositary. The Company shall make all payments in respect of a certificated Security (including principal, premium and interest), at the Company’s option, at the corporate trust office of the Trustee or by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security shall be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

If any scheduled payment date falls on a day that is not a Business Day, the applicable payment to be made on such payment date will be made on the next Business Day with the same force and effect as if made on the relevant payment date. No interest will accrue on such payment for the period from and after the applicable payment date.

The Company issued the Securities under an Indenture dated as of December 23, 2015, among the Company, the Subsidiary Guarantors, the Trustee and the Collateral Trustee (“Indenture”). The terms of the Securities include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture for a statement of those terms. The Securities are entitled to the benefits of the Security Documents, subject to the terms of the Intercreditor Agreement, all as more fully set forth in the Indenture.

The Company shall be entitled to issue Additional Securities pursuant to Section 2.03 of the Indenture. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single series for all purposes under the Indenture.

Except as set forth below in this paragraph 4 or paragraph 5, or in the Indenture, the Company shall not be entitled to optionally redeem the Securities prior to December 15, 2018.

At any time prior to December 15, 2018, the Company shall be entitled at its option to redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus the Make-Whole Premium as of, and accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). Any redemption pursuant to this paragraph 4 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.07 of the Indenture.

The Trustee shall have no responsibility or obligation whatsoever to calculate the Adjusted Treasury Rate or the Make-Whole Premium in connection with any redemption hereunder. Such responsibility shall be solely that of the Company.

For the purposes of this paragraph 4, the following terms shall have the meaning indicated:

“Adjusted Treasury Rate” means, with respect to any redemption date, the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Federal Reserve Statistical Release H.15 (519) or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System (or, if such release (or any successor release) is not published, any publicly available source of similar market data) and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after December 15, 2018, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), calculated on the third Business Day immediately preceding the redemption date, plus 50 basis points.

“Comparable Treasury Issue” means the United States Treasury security selected by the Company as having a maturity comparable to the remaining term of the Securities from the redemption date to December 15, 2018 that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity most nearly equal to December 15, 2018.

“Make-Whole Premium” means with respect to a Security at any applicable redemption date, the excess of (i) the present value at such redemption date of (A) the redemption price of such Security on December 15, 2018 (such redemption price being described in paragraph 5 below) exclusive of any accrued interest plus (B) all required remaining scheduled interest

payments due on such Security through December 15, 2018 (but excluding accrued and unpaid interest to the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate, over (ii) the principal amount of such Security on such redemption date.

(a) At any time on or after December 15, 2018, the Company may redeem the Securities, in whole or in part, at its option, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period (or, in the case of the period commencing December 15, 2020, such 12-month period and thereafter) commencing on December 15 of the years set forth below:

(b) At any time prior to December 15, 2018, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Securities issued under the Indenture at a redemption price equal to 108.00% of the principal amount of the Securities redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings by the Company; provided that, with respect to each such redemption, (i) at least 65% of the aggregate principal amount of Securities issued under the Indenture (excluding any Securities held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and (ii) such redemption occurs within 180 days of the date of the closing of such Equity Offering.

(c) Any redemption pursuant to this paragraph 5 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.07 of the Indenture.

If this Security would otherwise constitute “applicable high yield discount obligations” (“AHYDOs”) within the meaning of Section 163(i)(1) of the Code, at the end of all accrual periods ending after December 23, 2020 (each, an “AHYDO Payment Date”), but not including the final accrual period, the Company will make pro-rata cash payments to all Holders of this Security then outstanding in an amount equal to the Mandatory Principal Payment Amount (each such payment, a “Mandatory Principal Payment”). The “Mandatory Principal Payment Amount” means the portion of this Security’s principal required to be paid as of each AHYDO Payment Date to prevent this Security from being treated as an AHYDO within the meaning of Section 163(i)(1) of the Code. No partial payments, redemptions or repurchases of this Security

prior to an AHYDO Payment Date pursuant to any other provision of the Indenture or this Security will alter the Company’s obligation to make the Mandatory Principal Payment with respect to the amount of this Security that remain outstanding on an AHYDO Payment Date. Solely for U.S. federal income tax purposes, any Mandatory Principal Payment shall be treated as a payment of accrued OID that constitutes interest for purposes of Section 163(i)(2) of the Code.

Any Mandatory Principal Payment paid with respect to Global Securities will be processed as a “partial redemption” through the Depositary, in accordance with its rules and procedures as a “Pro Rata Pass-Through Distribution of Principal.”

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first class mail (or otherwise give such notice in accordance with the Indenture) to each Holder of Securities to be redeemed at such Holder’s registered address. If less than all of the Securities are redeemed at any time, the Trustee shall select the Securities to be redeemed on a pro rata basis in accordance with the procedures of the Depositary, or, if the Securities are listed on any securities exchange, by any other method that complies with the requirements of such exchange; provided, however, that no Securities with a principal amount of $2,000 or less shall be redeemed in part. Unless the Company defaults in payment of the applicable redemption price, interest on the Securities to be redeemed shall cease to accrue on the applicable redemption date, whether or not such Securities are presented for payment.

(a) In the event of certain Sale/Leaseback Transactions, the Company may be required to make a Net Proceeds Offer to purchase on a pro rata basis all or any portion of each Holder’s Securities and any other Senior Indebtedness in respect of which such an offer to purchase is also required to be made, at 100% of the principal amount thereof, plus accrued and unpaid interest to the Net Proceeds Payment Date.

(b) In the event of certain Collateral Sales, the Company may be required to make a Collateral Sale Offer to purchase on a pro rata basis all or a portion of each Holder’s Securities and any other Parity Lien Debt containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, at 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of purchase.

The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with, or transfer all or substantially all of its assets to, any other Person, sell and lease back certain of its properties or assets, the ability of the Company or any Restricted Subsidiary to incur encumbrances securing funded debt against certain property and the ability of the Company or any Restricted Subsidiary to sell certain Collateral, all subject to certain exceptions and limitations described in the Indenture.

The Securities are general senior obligations of the Company, secured on a second lien basis by the Collateral pledged by the Company. The Company’s obligation to pay principal, premium, if any, and interest with respect to the Securities is unconditionally guaranteed on a senior basis, jointly and severally, by the Subsidiary Guarantors pursuant to Article Ten of the Indenture, secured on a second-priority basis by the Collateral pledged by the Subsidiary Guarantors. Certain limitations to the obligations of the Subsidiary Guarantors are set forth in further detail in the Indenture.

The Securities are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an interest payment date.

Each Holder, by accepting a Security, shall be deemed to have agreed to and accepted the terms and conditions of the Security Documents and the Intercreditor Agreements and the performance by the Trustee and the Collateral Trustee of their respective obligations and the exercise of their respective rights thereunder and in connection therewith.

The registered Holder of this Security may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture and to the release of liens on the Collateral if the Company deposits with the Trustee money or U.S. Government Securities for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

The amendment, supplement and waiver provisions are set forth in the Indenture. Subject to certain exceptions, the Indenture, the Securities or the other Note Documents may be amended or supplemented with the consent of the Holders of at least a majority of the outstanding principal amount of the Securities, and any past default or noncompliance with any provision may be waived with the consent of the Holders of a majority in principal amount of the Securities. Without the consent of any Holder, the Company may amend or supplement the Indenture, the Securities or the other Note Documents to, among other things, cure any ambiguity, defect or inconsistency or to make any change that does not adversely affect the rights of any Holder in any material respect.

When a successor obligor assumes all the obligations of its predecessor under the Securities, the Indenture and the other Note Documents, the predecessor obligor shall be released from those obligations.

The defaults, events of default and remedies provisions are set forth in the Indenture. An Event of Default generally is: (i) default by the Company or any Subsidiary Guarantor in payment of principal of, or premium, if any, on the Securities; (ii) default by the Company or any Subsidiary Guarantor for 30 days in payment of interest on the Securities; (iii) defaults resulting in acceleration prior to maturity of certain other Indebtedness or resulting from payment defaults under certain other Indebtedness; (iv) failure by the Company or any Subsidiary Guarantor for 60 days after notice to comply with any of its other agreements in the Indenture; (v) a failure of any Guarantee of a Subsidiary Guarantor to be in full force and effect or denial by any Subsidiary Guarantor of its obligations with respect thereto; (vi) certain events of bankruptcy, insolvency or reorganization; and (vii) except as permitted by the Note Documents, certain Note Documents or Parity Liens cease for any reason to be enforceable or, in certain cases, perfected, or denial by a Mortgagor of its obligations with respect thereto. Subject to certain limitations in the Indenture, if an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization, all outstanding Securities shall become due and payable immediately without further action or notice. Holders may not enforce the Note Documents except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it before it enforces the Note Documents. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Company must furnish an annual compliance certificate to the Trustee.

Each of the Trustee and the Collateral Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, the Subsidiary Guarantors or their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee or Collateral Trustee, as applicable.

A director, officer, employee or stockholder, as such, of the Company, any Subsidiary Guarantor, the Trustee or the Collateral Trustee shall not have any liability for any obligations of the Company, any Subsidiary Guarantor, the Trustee or the Collateral Trustee or of any Affiliate of any of the foregoing entities under the Note Documents or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of this Security.

This Security shall not be valid until the Trustee or an authenticating agent signs the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=Custodian), and U/G/M/A (=Uniform Gifts to Minors Act).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company shall cause CUSIP numbers and corresponding ISIN numbers to be printed on the Securities as a convenience to Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

The Company shall furnish to any Holder upon written request and without charge to the Holder a copy of the Indenture. Requests may be made to:

Signatures must be guaranteed by an “eligible guarantor institution” meeting the requirements of the Registrar, which requirements include membership or participation in the Security Transfer Agent Medallion Program (“STAMP”) or such other “signature guarantee program” as may be determined by the Registrar in addition to, or in substitution for, STAMP, all in accordance with the Securities Exchange Act of 1934, as amended.

[Include the following only if the Restricted Securities Legend is included hereon]

In connection with any transfer of any of the Securities evidenced by this certificate occurring prior to one year (or such shorter period as is prescribed by Rule 144 under the Securities Act as then in effect or any successor rule without any volume or manner of sale restrictions or compliance by the Company with any current public information requirements thereunder) after the later of the date of original issuance of such Securities and the last date, if any, on which such Securities were owned by the Company or any Affiliate of the Company (or, in the case of Regulation S Securities, prior to the expiration of the Restricted Period), the undersigned confirms that such Securities are being transferred in accordance with their terms:

Unless one of the boxes is checked, the Trustee will refuse to register any of the Securities evidenced by this certificate in the name of any person other than the registered holder thereof; provided, however, that if box (4) or (5) is checked, the Company and the Trustee shall be entitled to require, prior to registering any such transfer of the Securities, such legal opinions, certifications and other information as each of the Company and the Trustee has reasonably requested to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act of 1933.

The undersigned represents and warrants that it is purchasing this Security for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act of 1933, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company and any Subsidiary Guarantors as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon the undersigned’s foregoing representations in order to claim the exemption from registration provided by Rule 144A.
