(e) Neither the Company nor the Registrar shall be required (1) to issue, to register the transfer of or to exchange any Note during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection, (2) to register the transfer of or to exchange any Note so selected for redemption, or tendered for repurchase (and not withdrawn) in connection with a Change of Control Offer or an Asset Sale Offer, in whole or in part, except the unredeemed or unpurchased portion of any Note being redeemed or repurchased in part or (3) to register the transfer of or to exchange any Note between a Record Date and the next succeeding Interest Payment Date.

Section 2.07     Replacement Notes .

If a mutilated Note is surrendered to the Trustee or if a Holder claims that its Note has been lost, destroyed or wrongfully taken and the Trustee receives evidence to its satisfaction of the ownership and loss, destruction or theft of such Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are otherwise met. If required by the Trustee or the Company, an indemnity bond must be provided by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Note. Every replacement Note is a contractual obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. Notwithstanding the foregoing provisions of this Section 2.07, in case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Section 2.08     Outstanding Notes .

(a) The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; provided that Notes held by the Company or a Subsidiary of the Company will not be deemed to be outstanding for purposes of Section 3.07(b).

(b) If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser, as such term is defined in Article 8-303 of the Uniform Commercial Code in effect in the State of New York.

(c) If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue from and after the date of such payment.

(d) If a Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on the maturity date, any redemption date or any date of purchase pursuant to an Offer to Purchase, money sufficient to pay Notes payable or to be redeemed or purchased on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.09     Treasury Notes .

In determining whether the Holders of the requisite principal amount of Notes have concurred in any direction, waiver or consent, Notes beneficially owned by the Company, or by any Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Company or any obligor upon the Notes or any Affiliate of the Company or of such other obligor.

Section 2.10     Temporary Notes .

Until definitive Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes.

Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Indenture.

Section 2.11     Cancellation .

Certification of the destruction of all cancelled Notes shall, upon the written request of the Company, be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12     Defaulted Interest .

(a) If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12.

The Trustee shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest.

(b) Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue interest, which were carried by such other Note.

The Company in issuing the Notes may use CUSIP or ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP or ISIN numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or in Offers to Purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange or Offer to Purchase shall not be affected by any defect in or omission of such numbers.

(a) Subject to Section 3.09, the Company shall mail by first-class mail (or deliver electronically if DTC is the recipient in accordance with the applicable procedures of the Depositary), or cause to be mailed (or delivered by electronic transmission in accordance with the applicable procedures of the Depositary) notices of redemption of Notes not less than 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed pursuant to this Article at such Holder’s registered address or otherwise in accordance with the applicable procedures of the Depositary, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with Article 8 or Article 11.

(b) The notice shall identify the Notes to be redeemed (including CUSIP and ISIN number, if applicable) and shall state:

(1) the redemption date;

(2) the redemption price, including the portion thereof representing any accrued and unpaid interest; provided that in connection with a redemption under Section 3.07(a), the notice need not set forth the redemption price but only the manner of calculation thereof;

(3) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed;

(4) the name and address of the Paying Agent;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph or subparagraph of the Notes or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(8) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on the Notes; and

(9) if applicable, any condition to such redemption.

(c) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided that the Company shall have delivered to the Trustee, at least two Business Days before notice of redemption is required to be sent or caused to be sent to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), 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 3.03(b).

Section 3.04     Effect of Notice of Redemption .

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price (except as provided for in Section 3.07(f)). The notice, if mailed or delivered by electronic transmission in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

Section 3.05     Deposit of Redemption or Purchase Price .

(a) No later than 11:00 a.m. (New York City time) on the redemption or purchase date (or such later time as such date to which the Trustee may reasonably agree), the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date.

The Paying Agent shall promptly mail to each Holder whose Notes are to be redeemed or repurchased the applicable redemption or

purchase price thereof and accrued and unpaid interest thereon. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased.

(b) If the Company complies with the provisions of Section 3.05(a), on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the redemption or purchase date in respect of such Note will be paid on such redemption or purchase date to the Person in whose name such Note is registered at the close of business on such Record Date. If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and, to the extent lawful, on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Section 3.06     Notes Redeemed or Purchased in Part .

Promptly after the determination thereof, the Company shall give the Trustee notice of the redemption price provided for in this Section 3.07(a), and the Trustee shall not be responsible for such calculation.

(b) Prior to January 15, 2021, the Company may on any one or more occasions redeem up to 35% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes) with the net cash proceeds of one or more Equity Offerings, upon notice pursuant to Section 3.03, at a redemption price equal to 105.375% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the applicable redemption date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date; provided that (1) at least 65% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes but excluding any Notes held by the Company and its Subsidiaries) remains outstanding immediately after the

(e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06.

(f) Any redemption notice in connection with this Section 3.07 may, at the Company’s discretion, be subject to one or more conditions precedent, including completion of any related Equity Offering. If such redemption is subject to the satisfaction of one or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the date of redemption may be delayed until such time as any or all such conditions shall be satisfied or waived ( provided that in no event shall such date of redemption be delayed to a date later than 60 days after the date on which such notice was sent), 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 or waived by the date of redemption, or by the date of redemption as so delayed.

In the event that, pursuant to Section 4.16 hereof, the Company is required to commence an Asset Sale Offer to all Holders to purchase Notes, the Company will follow the procedures specified below.

(a) The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that ranks pari passu in right of payment with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “ Asset Sale Offer Period ”). No later than three Business Days after the termination of the Asset Sale Offer Period (the “ Asset Sale Purchase Date ”), the Company will apply all Excess Proceeds (the “ Asset Sale Offer Amount ”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered, if applicable) or, if less than the Asset Sale Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

(b) If the Asset Sale Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest, if any will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

(c) Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, or send electronically if DTC is the recipient, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.16 and the length of time the Asset Sale Offer will remain open;

(2) the Asset Sale Offer Amount, the purchase price and the Asset Sale Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest on and after the Asset Sale Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;

(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Asset Sale Purchase Date;

(7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, electronic image scan, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Asset Sale Offer Amount allocated to the purchase of Notes in the Asset Sale Offer, the Trustee will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented by a Global Note shall be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law) based on the principal amount of Notes surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer) .

On or before the Asset Sale Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 3.09 and Section 4.16 hereof, or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Asset Sale Purchase Date.

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(ii)    any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any Preferred Stock; provided, however , that:

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business and not for speculative purposes;

(d) For purposes of determining compliance with Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Section 4.09(b)(1) through (15), or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that complies with Section 4.09. Indebtedness under the Credit Agreement outstanding on the Issue Date will be deemed to have been initially incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest or Preferred Stock or Disqualified Stock dividends or distributions, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness not secured by a Lien in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends or distributions on Preferred Stock or Disqualified Stock in the form of additional shares or units of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.09; provided , in each such case, that the

amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term.

(e) The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(i) the Fair Market Value of such assets at the date of determination; and

(ii) the amount of the Indebtedness of the other Person.

Section 4.10     Limitation on Liens .

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume any Lien (an “ Initial Lien ”) of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets now owned or hereafter acquired, unless the Notes or any Note Guarantee of such Restricted Subsidiary, as applicable, are secured on an equal and ratable basis with the Indebtedness so secured until such time as such Indebtedness is no longer secured by the Initial Lien.

(b) Any Lien created for the benefit of Holders pursuant to this

(c) Section 4.10 shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

Section 4.12     Limitation on Restrictions on Distribution From Restricted Subsidiaries .

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that the priority that any series of Preferred Stock of a Restricted Subsidiary has in receiving dividends, distributions or liquidating distributions before dividends, distributions or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this covenant;

(2) make loans or advances to the Company or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any of its Restricted Subsidiaries to other Indebtedness incurred by the Company or any of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(b) Section 4.12(a) will not apply to encumbrances or restrictions existing under or by reason of:

(2) this Indenture, the Notes and the Note Guarantees;

(3) agreements governing other Indebtedness permitted to be incurred under Section 4.09 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions contained therein are, in the reasonable good faith judgment of an officer of the Company, either (a) not materially more restrictive, taken as a whole, than those contained in this Indenture, the Notes and the Note Guarantees or the Credit Agreement as in effect on the Issue Date or (b) not reasonably likely to have a material adverse effect on the ability of the Company to make required payments on the notes;

(4) applicable law, rule, regulation or order;

(5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided , that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of an officer of the Company, no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided further , that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the reasonable good faith judgment of an officer of the Company, not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(10) Liens permitted to be incurred under the provisions of Section 4.10 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements;

(14) customary encumbrances and restrictions contained in agreements of the types described in the definition of “Permitted Business Investments.”

Section 4.13     Designation of Restricted and Unrestricted Subsidiaries .

(a) The Board of Directors of the Company may designate any Restricted Subsidiary of the Company to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary of the Company is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be either:

(1) an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under Section 4.08 hereof; or

(2) a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

(b) Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.08 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date. If such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant.

(c) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of

the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if:

(1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and

(2) no Default or Event of Default would be in existence following such designation.

Section 4.14     Transactions with Affiliates .

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company involving aggregate consideration in excess of $5.0 million (each, an “ Affiliate Transaction ”), unless :

(1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(2) the Company delivers to the Trustee:

(i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.14; and

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.14 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any.

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.14(a) hereof:

(1) any employment or consulting agreement, employee benefit plan, officer or director indemnification, compensation or severance agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto;

(2) transactions between or among the Company or its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) payment of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries;

(6) Restricted Payments that do not violate the provisions of Section 4.08 hereof and any Permitted Investment;

(7) payments to an Affiliate in respect of the Notes or any other Indebtedness of the Company or any of its Restricted Subsidiaries on the same basis as concurrent payments are made or offered to be made in respect thereof to non-Affiliates;

(8) loans or advances to or reimbursements of expenses incurred by employees for moving, entertainment and travel expenses and similar expenditures in the ordinary course of business;

(9) transactions between the Company or any of its Restricted Subsidiaries and any other Person, a director of which is also on the Board of Directors of the Company or any direct or indirect Parent Entity, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Company or any of its Restricted Subsidiaries; provided, however , that such director abstains from voting as a member of the Board of Directors of the Company or any direct or indirect Parent Entity, as the case may be, on any transaction with such other Person;

(10) in the case of contracts for exploring for, producing, marketing, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts entered into in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to the Company and its Restricted Subsidiaries or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party, in either case in the reasonable determination of the Board of Directors of the Company or the senior management thereof;

(11) transactions with customers, clients, suppliers, contractors, joint venture partners or purchasers or sellers of goods or services (other than an Unrestricted Subsidiary), or transactions otherwise relating to the purchase or sale of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into

account all the costs and benefits associated with such transactions), not materially less favorable to the Company or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person, as determined in good faith by the Company, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; and

(12) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.14(a)(1) hereof.

(a) Upon the occurrence of a Change of Control, except as provided in this Section 4.15, the Company will make an offer (a “ Change of Control Offer ”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash (the “ Change of Control Payment ”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “ Change of Control Purchase Date ”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Company will send a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the expiration date of the Change of Control Offer, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent;

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, electronic image scan, facsimile transmission or letter setting forth the name of the Holder, the principal

amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

(2) deliver or cause to be delivered to the Trustee the Notes accepted for payment, together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company will announce publicly the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change of Control if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (ii) notice of redemption of all outstanding Notes has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price, or (iii) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “ Alternate Offer ”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer.

(d) Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned

upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made. The closing date of any Change of Control Offer or Alternate Offer made in advance of a Change of Control may be changed to conform to the actual closing date of the Change of Control; provided that such closing date is not earlier than 30 days nor later than 60 days from the date the Change of Control Offer notice is sent pursuant to Section 4.15(a) hereof.

(e) In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or a third party making the Change of Control Offer or Alternate Offer in lieu of the Company as described in paragraph (c) above) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment, plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain outstanding to, but excluding, the date of redemption (subject to the rights of Holders on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date).

Section 4.16     Asset Sales .

The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale, unless :

(a) the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(b) at least 75% of the aggregate consideration received in the Asset Sale by the Company or such Restricted Subsidiary and all other Asset Sales since the Issue Date is in the form of cash or Cash Equivalents.

For the purposes of this Section 4.16(b) and for no other purpose, the following will be deemed to be cash:

(1) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed or otherwise forgiven by the transferee of any such assets pursuant to a novation, indemnity or other agreement that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against further liability;

(2) with respect to any Asset Sale of oil and natural gas properties by the Company or any of its Restricted Subsidiaries where the Company or such Restricted Subsidiary retains an interest in such property, the aggregate costs and expenses of the Company or such Restricted Subsidiary related to the exploration,

development, completion or production of such properties and activities related thereto that the transferee (or an Affiliate therefor) agrees to pay;

(3) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days of the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(4) any Capital Stock or assets of the kind referred to in Section 4.16(c)(2) or (4) hereof; and

(5) any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.16(b)(5), not to exceed an amount equal to 3.0% of the Company’s Adjusted Consolidated Net Tangible Assets (determined at the time of 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.

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or one or more of its Restricted Subsidiaries may apply an amount equal to the amount of such Net Proceeds at its option to any combination of the following:

(1) to repay, repurchase or redeem any senior Indebtedness of the Company or any Subsidiary Guarantor, in each case owing to a Person other than the Company, any Restricted Subsidiary or any Parent Entity;

(2) to acquire all or substantially all of the assets, or any Capital Stock, of one or more other Persons primarily engaged in the Oil and Gas Business, if, after giving effect to any such acquisition of Capital Stock, such Person becomes a Restricted Subsidiary of the Company;

(3) to make capital expenditures in respect of the Company’s or any of its Restricted Subsidiaries’ Oil and Gas Business; or

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business.

(d) The requirements of Section 4.16(c)(2) or (4) hereof shall be deemed to be satisfied if a bona fide binding commitment to make the acquisition referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such commitment within 180 days following the date such commitment is entered into.

(e) Pending the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(f) Net Proceeds from Asset Sales that are not applied or invested as provided in paragraphs (c) and (d) of this Section 4.16 will constitute “ Excess Proceeds. ” When the aggregate amount of Excess Proceeds exceeds $20.0 million, within five days thereof, the Company will make an offer (an “ Asset Sale Offer ”) to all Holders of Notes and all Holders of other Indebtedness that ranks pari passu in right of payment with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem such Indebtedness with the proceeds of sales of assets, to purchase, prepay or redeem, on a pro rata basis, the maximum principal amount of Notes and such other pari passu Indebtedness ( plus all accrued interest on the Notes and other Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by   this Indenture. If the aggregate principal amount of Notes tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds allocated to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(g) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to a Change of Control Offer, Alternate Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with Section 3.09, Section 4.15 or this Section 4.16, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09, Section 4.15 or this Section 4.16 by virtue of such compliance.

Section 4.17     Effectiveness of Covenants .

(a) If on any date following the Issue Date: (i) the Notes are rated Baa3 or better by Moody’s or BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Company as a replacement agency); and (ii) no Default or Event of Default shall have occurred and is continuing under this Indenture, then, beginning on that date, and, subject to the provisions of this Section 4.17, the following provisions of this Indenture shall be suspended:

(c) Notwithstanding the foregoing, if the ratings assigned to the Notes by both such ratings agencies should subsequently decline to below Baa3 or BBB- from Moody’s or S&P, respectively, the foregoing covenants will be reinstituted as of and from the date both such ratings were below investment grade. Calculations under the reinstated Section 4.08 hereof will be made as if Section 4.08 hereof had been in effect since the Issue Date except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while that covenant was suspended. Furthermore, all Indebtedness incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be deemed to have been incurred or issued pursuant to Section 4.09(b)(2). In addition, for purposes of Section 4.14 hereof, all agreements and arrangements entered into by the Company or any Restricted Subsidiary with an Affiliate of the Company during the Suspension Period will be deemed to have been entered into prior to the Issue Date and permitted by Section 4.14(b)(7) hereof, and for purposes of Section 4.12 hereof, all contracts entered into during the Suspension Period that contain any of the restrictions contemplated by such covenant will be deemed to have been existing on the Issue Date.

Section 6.05     Control by Majority .

The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.

Section 6.09     Restoration of Rights and Remedies .

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy are, to the extent permitted by law, cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.11     Delay or Omission Not Waiver .

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

Section 6.12     Trustee May File Proofs of Claim .

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 Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) through (4) below, and to have satisfied all of their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, on, or interest on the Notes when such payments are due from the trust referred to in Section 8.04;

(2) the Company’s obligations with respect to the Notes under Article 2 and Section 4.02 hereof;

For this purpose, Covenant Defeasance means that, with respect to this Indenture, the outstanding Notes and Note Guarantees, the Company and the Subsidiary Guarantors 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, such Notes and Note Guarantees shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, Section 6.01(a)(3), (4), (5) (with respect to defaults under Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.17), (6), (7), (8), (9) (only with respect to Significant Subsidiaries or any group of Restricted Subsidiaries that taken together (as of the date of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary) and (10) (only with respect to Significant Subsidiaries or any group of Restricted Subsidiaries that taken together (as of the date of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary) hereof will not constitute Events of Default.

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

(c) It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver. It shall be sufficient if such consent approves the substance of such proposed amendment, supplement or waiver.

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will give to the Holders a notice briefly describing such amendment, supplement or waiver.

(f) A consent to any amendment, supplement or waiver of this Indenture, the Notes or the Note Guarantee by any Holder given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender.

Section 9.03     [Reserved] .

Section 9.04     Revocation and Effect of Consents .

(a) Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note.

ARTICLE 10

GUARANTEES

Section 10.01     Guarantee .

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, irrevocably and unconditionally guarantees, on a senior unsecured basis, to each Holder and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (1) the principal, premium, if any, and interest (including post-petition interest in any proceeding under any Bankruptcy Law) on the Notes shall be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal and interest on the Notes, if any, if lawful, and all other Obligations of the Company to the Holders or the Trustee hereunder or under the Notes shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise collectively, the “ Guaranteed Obligations ”. Failing payment by the Company when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the

Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture, or pursuant to Section 10.07.

(c) Each of the Guarantors also agrees, jointly and severally, to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(e) Each Guarantor agrees that 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 Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantees.

(f) Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or the Note Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(g) In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

(h) Each payment to be made by a Guarantor in respect of its Note Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Section 10.02     Limitation on Guarantor Liability .

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance or a fraudulent transfer for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Note Guarantee will be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment, determined in accordance with GAAP.

Section 10.03     Execution and Delivery .

(a) To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer or person holding an equivalent title.

(b) Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

(c) If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantees shall be valid nevertheless.

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.

(e) If required by Section 4.11, the Company shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.11 and this Article 10, to the extent applicable.

Section 10.04     Subrogation .

Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 10.01; provided that, if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Notes shall have been paid in full.

Section 10.05     Benefits Acknowledged .

Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Note Guarantee are knowingly made in contemplation of such benefits.

Section 10.06     Guarantors May Consolidate, etc., on Certain Terms .

A Guarantor may not: (1) consolidate or merge with or into another Person (whether or not such Guarantor is the surviving Person), or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of such Guarantor in one or more related transactions, to another Person, other than the Company or a Subsidiary Guarantor, unless:

(a) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default exists; and

(b) either:

(1) the Person acquiring the properties or assets in any such sale, assignment, transfer, conveyance or other disposition or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) unconditionally assumes all the obligations of that Guarantor under its Note Guarantee and this Indenture pursuant to a supplemental indenture, in form reasonably satisfactory to the Trustee; or

(2) the Net Proceeds of such transaction or series of transactions are applied in a manner that does not violate Section 4.16 hereof.

In case of any such consolidation, merger, sale or other disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee of the Guarantor and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Section 10.07     Release of Note Guarantees .

The Note Guarantee of a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Company or the Trustee shall be required for the release of such Guarantor’s Note Guarantee, upon:

(a) in the case of a Subsidiary Guarantor, in connection with any sale or other disposition of all or substantially all of the properties or assets of that Subsidiary Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.16 hereof;

(b) in the case of a Subsidiary Guarantor, in connection with any sale or other disposition of Capital Stock of that Subsidiary Guarantor by way of merger, consolidation or otherwise to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.16 hereof and such Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;

(c) if the Company designates such Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or

(a) Either:

(1) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

(2) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the giving of a notice of

redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, premium, if any, on, or interest on, the Notes to, but excluding, the date of Stated Maturity or redemption;

(b) in respect of Section 11.01(a)(2), no Event of Default has occurred and is continuing on the date of the deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings);

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

Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to Section 11.01(a)(2), the provisions of Section 11.02 and Section 8.06 shall survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02     Application of Trust Money .

(a) Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes 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, premium, if any, and interest for whose payment such money has been deposited with the Trustee, but such money need not be segregated from other funds except to the extent required by law.

(b) If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining,

restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture, the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Company has made any payment of principal, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent, as the case may be.
