ARTICLE 2
THE NOTES

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part hereof and the Company, the Guarantors and the Trustee, by their execution and delivery hereof, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions hereof, the provisions hereof shall govern and be controlling.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for the Company by manual, facsimile, PDF or other electronic transmission signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated hereunder.

The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate Notes for original issue that may be validly issued hereunder, including (i) on the Issue Date, the Initial Notes and (ii) after the Issue Date, any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference herein to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.03 Registrar and Paying Agent.

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent (at its offices indicated in the definition of Corporate Trust Office of the Trustee in Section 1.01 hereof) and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest, if any, on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Restricted Subsidiary) will have no further liability for the money. If the Company or a Restricted Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any

bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Company will furnish to the Trustee at least two Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if:

(1) The Depositary (A) notifies the Company that it is unwilling or unable to continue as Depositary or (B) has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary;

(2) the Company, at its option but subject to the Depositary’s requirements, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes; or

(3) there has occurred and is continuing an Event of Default, and the Depositary notifies the Trustee of its decision to exchange such Global Notes for Definitive Notes.

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Except as specified above, every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06, Section 2.07 or Section 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions hereof and the Applicable Procedures. Beneficial

If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

Every replacement Note is an additional obligation of the Company and will be entitled to all of the benefits hereof equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee or authenticating agent except for those canceled by the Trustee, those delivered to the Trustee 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 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

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

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee or authenticating agent, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee or authenticating agent will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits hereof.

Section 2.11 Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate

provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will send or cause to be sent (or when the Notes are represented by Global Notes, send or caused to be sent electronically pursuant to the Applicable Procedures of the Depositary) to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

ARTICLE 3
REDEMPTION AND PREPAYMENT

Section 3.01 Election to Redeem; Notices to Trustee.

If the Company elects to redeem Notes pursuant to the optional redemption provisions hereof, it must furnish to the Trustee, at least two Business Days (or such shorter period acceptable to the Trustee) before a redemption date, an Officer’s Certificate setting forth:

(1) the clause hereof pursuant to which the redemption shall occur;

(2) the redemption date;

(3) the principal amount of Notes to be redeemed; and

(4) the redemption price.

Other than an optional redemption made by an affirmative election of the Company pursuant to this Section 3.01 and Section 3.03, no payment, purchase, redemption, repurchase, defeasance, exchange or other acquisition, retirement for value or satisfaction of Notes (including any payment made or deemed made after acceleration of the Notes) shall constitute an optional redemption of the Notes for purposes of Section 3.07 hereof and paragraph 5 of the Notes.

Any redemption notice or offer to purchase may, at the Company’s discretion, be subject to the satisfaction or waiver of one or more conditions precedent, including the completion of an Equity Offering or other transaction (or series of related transactions). In addition, if such redemption or offer to purchase is subject to satisfaction or waiver of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied or waived, 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 redemption date, or by the redemption date so delayed.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, based on a method as the Depositary or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by law or applicable stock exchange or depositary requirements.

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions hereof that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

Subject to the provisions of Sections 3.08 and 3.11 hereof, at least 10 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed by first class mail (or when the Notes are represented by Global Notes, sent electronically pursuant to the Applicable Procedures of the Depositary), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed (or otherwise sent) more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge hereof pursuant to Articles 8 or 11 hereof.

The notice will identify the Notes to be redeemed and will state:

(1) the redemption date;

(2) the redemption price;

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note;

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

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

(6) that, unless the Company defaults in making such redemption payment or the conditions precedent to the redemption are not satisfied, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section hereof pursuant to which the Notes called for redemption are being redeemed;

(8) any condition to such redemption; and

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

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at their expense; provided, however, that the Officer’s Certificate delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee give such notice and sets forth the information to be stated in such notice as provided in the preceding paragraph. The notice of redemption with respect to a redemption pursuant to Section 3.07(c) need not set forth the Applicable Premium but only the manner of calculation thereof. The Company will notify the Trustee of the Applicable Premium with respect to any such redemption promptly after the calculation, and the Trustee shall not be responsible for such calculation.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price unless such redemption is conditioned on the happening of a future event and such condition as described in the notice of redemption is not satisfied. The notice, if sent in a manner provided herein, 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.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased.

If the Company complies with the provisions of the preceding paragraph and, if the redemption is conditional, the conditions precedent to the redemption are satisfied, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an

interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue, and, if the Note is a Definitive Note, upon receipt of an Authentication Order, the Trustee or authenticating agent will authenticate for the Holder at the expense of the Company, a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

(a) Except pursuant to Section 3.07(b), (c), or (d), Section 3.10 or Section 4.14(e) hereof, the Notes will not be redeemable at the Company’s option.

(b) At any time prior to June 1, 2023, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount of Notes issued hereunder at a redemption price equal to 106.375% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided that:

(1) at least 60% of the aggregate principal amount of the Notes (including Additional Notes, if any) originally issued hereunder (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

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

(c) At any time prior to June 1, 2023, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

(d) On or after June 1, 2023, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 10 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth

below, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, if redeemed during the twelve-month period beginning on June 1 of the years indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date:


Year			Percentage
2023			103.188%
2024			101.594%
2025 and thereafter			100.000%

(e) Unless the Company defaults in the payment of the redemption price, or the redemption is subject to satisfaction of one or more conditions precedent and such conditions precedent are not satisfied, the Notes will become due and payable and interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(f) Any redemption pursuant to this Section 3.07 or Section 4.14(e) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section 3.08 Special Mandatory Redemption.

In the event that (a) the Acquisition is not consummated on or prior to September 27, 2021 (or such later date that is the “Outside Date” as defined in and under the Acquisition Agreement) or (b) at any time prior to September 27, 2021 (or such later date that is the “Outside Date” as defined in and under the Acquisition Agreement), the Acquisition Agreement is terminated without the Acquisition being consummated (any such event being a “Special Mandatory Redemption Event”), the Company will redeem all of the Notes (the “Special Mandatory Redemption”), at a price equal to 100% of the issue price of the Notes plus accrued and unpaid interest to, but excluding, the date of redemption date (the “Special Mandatory Redemption Price”). For purposes of the foregoing, the Acquisition will be deemed consummated if the closing under the Acquisition Agreement occurs, including after giving effect to any amendments to the Acquisition Agreement or waivers thereunder acceptable to the Company.

Notice of the occurrence of a Special Mandatory Redemption Event and that a Special Mandatory Redemption is to occur (the “Special Mandatory Redemption Notice”), shall be delivered to the Trustee and delivered to Holders of Notes according to the procedures of DTC within 10 Business Days after the Special Mandatory Redemption Event. At the Company’s written request, the Trustee shall give the Special Mandatory Redemption Notice in the Company’s name and at the Company’s expense. On the redemption date specified in the Special Mandatory Redemption Notice, which shall be no more than 10 Business Days (or such other minimum period as may be required by DTC) after mailing or sending the Special Mandatory Redemption Notice, the special mandatory redemption shall occur (the date of such redemption, the “Special Mandatory Redemption Date”).

If funds sufficient to pay the Special Mandatory Redemption Price of all of the Notes on the Special Mandatory Redemption Date are deposited with a Paying Agent or the Trustee on or before such Special Mandatory Redemption Date, then on and after such Special Mandatory Redemption Date, the Notes shall cease to bear interest and, other than the right to receive the Special Mandatory Redemption Price, all rights under such Notes shall terminate.

Upon the consummation of the Acquisition, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

Section 3.09 Use of Proceeds Prior to the Consummation of the Acquisition.

Prior to the earlier of (A) the date of the consummation of the Acquisition and (B) the date on which the Notes are redeemed by the Company pursuant to the special mandatory redemption provisions described in Section 3.08, the Company will not, and will not permit any of its Subsidiaries to, use the net proceeds from the issuance of the Notes for any other purpose other than making investments in Cash Equivalents or consummating the Acquisition.

Upon the consummation of the Acquisition, this covenant will automatically cease to be of any force or effect.

Section 3.10 Mandatory Redemption.

Except as required by Section 3.08, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company may at any time and from time to time purchase Notes in the open market or otherwise, in each case without any restriction hereunder.

Section 3.11 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an Asset Sale Offer, it will follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth herein 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 “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase, prepayment or redemption 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 (except that any Notes represented by a Global Note will be selected by such method as the Depositary or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law or applicable stock exchange or depositary requirements)) or, if less than the

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.

If the Purchase Date is on or after an interest 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.

Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail (or when the Notes are represented by Global Notes, send electronically pursuant to the Applicable Procedures of the Depositary), a notice to each of the Holders, with a copy to the Trustee. 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 3.11 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the 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 after the 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 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 and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased, prepaid or redeemed 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 or applicable stock exchange or depositary requirements) based on the principal amount of Notes and such other pari passu Indebtedness tendered or required to be prepaid or redeemed (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 Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.11. The Company, the Depositary 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 or promptly after the Purchase Date.

Other than as specifically provided in this Section 3.11, any purchase pursuant to this Section 3.11 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

ARTICLE 4

Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due.

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 fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served 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 Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain offices or agencies in the Borough of Manhattan, the City of New York 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 designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

Section 4.03 Reports.

(a) So long as any Notes are outstanding, the Company will furnish to the Holders of Notes or cause the Trustee to furnish to the Holders of Notes (or file or furnish, as applicable, with the SEC for public availability) within the time periods specified in the SEC’s rules and regulations applicable to the Company (or, in the event the Company is not so required, which would be applicable to the Company if it were required), after giving effect to all applicable extensions and cure periods:

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file reports with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, annual audited financial statements prepared in accordance with GAAP (with footnotes to such financial statements), including the audit report on such financial statements issued by the Company’s certified

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

To the extent the Company is not required to file any of the reports required by this covenant with the SEC, the Company, (i) as promptly as reasonably practicable after furnishing to the Trustee the reports and financial statements required by Section 4.03(a)(1), hold a conference call to discuss such reports and the results of operations for the relevant reporting period; provided that the Company may satisfy the requirements of this clause by holding the required conference call as part of any earnings call of the Company or any direct or indirect parent of the Company and (ii) shall issue a press release to an internationally recognized wire service no fewer than three Business Days prior to the date of the conference call required to be held in accordance with this paragraph, announcing the time and date of such conference call and either including all information necessary to access the call or directing noteholders, prospective investors, broker dealers and securities analysts to contact the appropriate person at the Company to obtain such information.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations of the SEC applicable to such reports.

(c) Any and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner a report or information required by this Section 4.03 shall be deemed cured (and the Company shall be deemed to be in compliance with this Section 4.03) upon furnishing or filing such report or information as contemplated by this Section 4.03 (but without regard to the date on which such report or information is so furnished or filed); provided that such cure shall not otherwise affect the rights of the Holders under Section 6.01 if the principal, interest and premium, if any, have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(d) In addition, the Company and the Guarantors will agree that, for so long as any Notes remain outstanding, to the extent not satisfied by Section 4.03(a), they will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the

information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

(e) This Section 4.03 will not impose any duty on the Company under the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the related SEC rules that would not otherwise be applicable. Any reports, information or documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval (▇▇▇▇▇) (or any successor) system shall be deemed furnished to the Holders of the Notes as required pursuant to this covenant. The Trustee does not have a duty or obligation to monitor whether the Company has so filed such reports, information or documents with the SEC or has otherwise made such reports, information and documents publicly available on its website.

(f) 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 their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Section 4.04 Compliance Certificate.

(a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officer’s Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled their respective obligations hereunder, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained herein 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 has occurred and is continuing, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or propose to take with respect thereto).

(b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.03 shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

(c) So long as any of the Notes are outstanding, the Company will deliver to the Trustee, within 30 days after any Officer becomes aware of any Event of Default, an Officer’s Certificate specifying such Event of Default and what action the Company is taking or propose to

take with respect thereto, unless such Event of Default has been cured before the end of such 30-day period.

(d) Delivery of such reports, information and documents under Section 4.03 and this Section 4.04 to the Trustee shall be for informational purposes only, and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including compliance with any of the covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Section 4.05 Taxes.

The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

The Company and each of the Guarantors covenants (to the extent that it 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 wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance hereof; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that (i) 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 and (ii) the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall be deemed not to be a restriction on the ability to make payments with respect to such loans or advances;

(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 Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall be deemed not to be a restriction on the ability to make loans or advances); or

(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; provided that, in the case of Indebtedness, such Indebtedness was not prohibited by the terms hereof to be incurred;

(6) customary non-assignment provisions in purchase and sale or exchange agreements for Hydrocarbons, agreements of the types described in Permitted Liens clause (17) or similar operational agreements, or in licenses, easements, leases or other contracts commonly used in a Permitted Business, including Farm-In Agreements and Farm-Out Agreements;

(8) any agreement for the sale or other disposition of a Restricted Subsidiary or any assets thereof that restricts distributions by that Restricted Subsidiary pending such sale or other disposition;

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

(10) Liens permitted to be incurred under the provisions of Section 4.12 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, shareholders’ agreements, partnership agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into in the ordinary course of business, which limitation is applicable only to the assets or properties that are the subject of such agreements;

(12) encumbrances or restrictions applicable only to a Restricted Subsidiary that is not a Domestic Subsidiary;

(13) any agreement with respect to any property or asset acquired after the Issue Date (including by merger or consolidation) as in effect at the time of such acquisition (except to the extent such agreement was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any property or assets other than the property or assets so acquired;

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

(a) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, if such Indebtedness is not unsecured and expressly subordinated in right of payment to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Guarantor, then the incurrence of such Indebtedness; and

(8) [reserved];

(9) the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to the Notes or a Note Guarantee, then the Guarantee must be subordinated to the same extent as the Indebtedness guaranteed (or, at the Company’s election, to a greater extent);

(16) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance by the Company of any Disqualified Stock in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred or Disqualified Stock issued pursuant to this clause (16), not to exceed the greater of (a) $100.0 million and (b) 5.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance and after giving effect to the use of proceeds thereof; and

(17) the incurrence of additional Indebtedness by Restricted Subsidiaries that are not Guarantors and Indebtedness incurred by the Company or any Restricted Subsidiary on behalf of, or representing guarantees of Indebtedness of, Joint Ventures of the Company and any Restricted Subsidiary in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (17), not to exceed the greater of (a) $50.0 million and (b) 3.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance and after giving effect to the use of proceeds thereof.

The Company will not incur, and the Company will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms (or, at the Company’s election, to a greater extent); provided, however, that no Indebtedness will be considered contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured, secured with different

collateral or to a greater or lesser extent or priority or by virtue of structural subordination, maturity date or being guaranteed by less than all guarantors of such other Indebtedness.

For purposes of determining compliance with this 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 (17) above, or is entitled to be incurred pursuant to Section 4.09(a), 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 this covenant. Indebtedness under Debt Facilities outstanding on the date on which Notes are first issued and authenticated hereunder will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt and may not later be reclassified. The accrual of interest or dividends, the accretion of principal, accreted value or liquidation preference, the amortization of original issue discount or debt discount, the payment of interest on Indebtedness in the form of additional Indebtedness, the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional securities of the same class of Preferred Stock or Disqualified Stock, the obligation to pay a premium in respect of Indebtedness or Preferred Stock or Disqualified Stock arising in connection with the issuance of a notice of redemption or the making of a mandatory change of control offer or asset sale offer for such Indebtedness or Preferred Stock or Disqualified Stock, increases in the amount of Indebtedness outstanding solely as a result of fluctuations in exchange rates or currency values, unrealized losses or charges in respect of Hedging Obligations, and the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, in each case will be deemed not to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this covenant; provided that the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term.

Section 4.10 Asset Sales.

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

(1) the Company (or a Restricted Subsidiary, 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 Equity Interests issued or the assets sold or otherwise disposed of; and

(2) at least 75% of the aggregate consideration received in the Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, by the Company or a Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (2) only, each of the following will be deemed to be cash:

(a) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (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 or released by the transferee of any such assets (or an Affiliate thereof);

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

(d) 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 clause (d) that is at that time outstanding, not to exceed the greater of (i) $85.0 million and (ii) 4.0% of the Adjusted Consolidated Net Tangible Assets at 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; and

(e) with respect to any Asset Sale of Oil and Gas Properties disposed of by the Company or any Restricted Subsidiary in which the Company or any Restricted Subsidiary retains an interest, 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).

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or any Restricted Subsidiary) may apply such Net Proceeds at its option to any combination of the following:

(1) to repay, purchase, repurchase, redeem, defease or otherwise acquire, retire or terminate: (a) Indebtedness and all other Obligations related thereto that are secured by a Lien; or (b) Obligations with respect to Indebtedness of a Restricted Subsidiary that is not a Guarantor (other than Indebtedness owed to the Company or another Restricted Subsidiary);

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

(3) to make capital expenditures in respect of the Company’s or any Restricted Subsidiary’s Permitted Business;

(4) to acquire assets (other than Capital Stock) that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or

(5) to make Investments in a Joint Venture not prohibited by Section 4.07, the proceeds of which will be applied by such Person to any combination of (i) repaying, purchasing, repurchasing, redeeming, defeasing or otherwise acquiring, retiring or terminating Indebtedness of such Person or a Subsidiary of such Person and other Obligations related thereto, (ii) acquiring all or substantially all of the assets of, or any Capital Stock of, one or more other Persons primarily engaged in a Permitted Business, (iii) making capital expenditures in respect of such Person’s Permitted Business, or (iv) acquiring assets (other than Capital Stock) that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.

(c) The requirement of clauses (2) through (4) and (5)(ii)-(iv) of Section 4.10(b) shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Company or any Restricted Subsidiary, as the case may be (or in the case of clause (5)(ii)-(iv), such Joint Venture), 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 contract within 180 days following the date such agreement is entered into.

(d) Pending the final application of any Net Proceeds, the Company (or any Restricted Subsidiary) may expend or invest the Net Proceeds in any manner that is not prohibited hereby, including temporarily reducing revolving credit borrowings.

(e) Any Net Proceeds from Asset Sales that are not applied as provided in Section 4.10(b) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $50.0 million, within 30 days thereafter, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes, and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth herein with respect to offers to purchase, prepay or redeem 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 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 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 Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited hereby. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased, prepaid or redeemed 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 or applicable stock exchange or depositary requirements), based on

the amounts tendered or required to be prepaid or redeemed (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. The Company may satisfy the foregoing obligation with respect to any Excess Proceeds by making an Asset Sale Offer prior to the expiration of the relevant 365-day period or with respect to Excess Proceeds of $50.0 million or less.

(f) 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 an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, the Company will comply with the applicable securities laws and regulations and will be deemed not to have breached its obligations under this Section 4.10 by virtue of such compliance.

(g) The provisions hereof relative to the Company’s obligation to make an offer to repurchase the Notes as a result of an Asset Sale may be amended, waived, modified or terminated with the consent of the Holders of a majority in principal amount of the outstanding Notes (including Additional Notes, if any).

(h) All references herein to “Net Proceeds” and “Excess Proceeds” shall be deemed to mean cash in an amount equal to the amount of Net Proceeds or Excess Proceeds but not necessarily the actual cash received from the relevant Asset Sale. The Company and its Subsidiaries shall have no obligation to segregate, trace or otherwise identify Net Proceeds or Excess Proceeds (other than the amount thereof), it being agreed that cash is fungible and that the Company’s obligations under this Section 4.10 may be satisfied by the application of funds from other sources.

Section 4.11 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 (which term, for purposes of this covenant, shall include “for the benefit of” where appropriate in the context) any Affiliate of the Company involving aggregate consideration in excess of $10.0 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 could 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 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:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant as determined in good faith by an Officer of the Company disinterested with respect to such Affiliate Transaction; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members (or, if there are no disinterested members, a majority of the members) of the Board of Directors of the Company.

(b) The following items will be deemed not to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

(1) any employment or consulting agreement or arrangement, equity award, equity option or equity appreciation agreement or plan, 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, awards, grants or issuances of securities pursuant thereto;

(2) transactions between or among the Company and/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 other benefits 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;

(5) any issuance of Equity Interests of the Company to or receipt of capital contributions from Affiliates of the Company and the granting of registration and other customary rights in connection therewith;

(6) Permitted Investments or Restricted Payments (and any other payments excluded from such definitions or their component definitions) that do not violate the provisions of Section 4.07 hereof;

(7) entry into, and transactions effected in accordance with the terms of, the agreements described in the Offering Memorandum or that are described in filings with the SEC that are incorporated by reference in the Offering Memorandum, in each case as such agreements are in effect on the Issue Date, and any amendment, renewal, extension or replacement of any of such agreements if any such amendment, renewal, extension or replacement agreement is not materially less advantageous to the Company, taken as a whole, than the agreement so amended, renewed, extended or replaced;

(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 permitted under clause (8) of the definition of Permitted Investments;

(9) 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, advisory 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 stating that the terms are not materially less favorable to the Company or such Restricted Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unaffiliated Person;

(10) in the case of contracts for exploiting, exploring for, drilling, acquiring, developing, producing, operating, processing, gathering, marketing, distributing, transporting, treating, selling, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, contracts of the types described in clause (17) of Permitted Liens, or other contracts commonly used in a Permitted Business, any such contracts entered into in the ordinary course of business and otherwise in compliance with the terms hereof (i) that are fair to the Company and its Restricted Subsidiaries, in the good faith judgment of the Board of Directors of the Company or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated Person and (ii) with respect to which the Company has complied with Section 4.11(a)(2)(A) if such clause would otherwise be applicable;

(11) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business that, in the good faith judgment of the Board of Directors or senior management of the Company, 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 Person;

(12) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that a director or manager of such Person is also a director or manager of the Company or a Restricted Subsidiary if such director or manager abstains from voting as a director or manager of the Company or such Restricted Subsidiary, as applicable, on such transaction;

(13) pledges by the Company or any Restricted Subsidiary of (and Guarantees by the Company or any Restricted Subsidiary limited in recourse solely to) Equity Interests in Unrestricted Subsidiaries and Joint Ventures to secure Non-Recourse Debt, and incurrences of liabilities with respect to Customary Recourse Exceptions; and

(14) any Affiliate Transaction with a Person in its capacity as a holder of Indebtedness or Equity Interests of the Company or any Restricted Subsidiary if such Person is treated no more favorably than the other similarly situated holders of Indebtedness or Equity Interests of the Company or such Restricted Subsidiary.

Section 4.12 Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur or assume or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless all payments due to the Holders under this Indenture and the Notes are secured on an equal and ratable basis with (or at the Company’s election, prior to) the Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien.

Section 4.13 Corporate Existence.

Except as otherwise permitted under Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its corporate existence, and the corporate, partnership, limited liability company or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership, limited liability company or other existence of any of its Subsidiaries, if the Board of Directors or senior management of the Company, or of a general partner of the Company if the Company is a partnership, shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.14 Offer to Repurchase Upon Change of Control Triggering Event.

principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to 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 Triggering Event, the Company will deliver a notice to each Holder describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes properly tendered prior to the expiration date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required hereby and setting forth the following:

(1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

(2) the amount of the Change of Control Payment and the Change of Control Purchase Date, which shall be no earlier than 10 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 Purchase 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 Purchase 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 Purchase Date, a telegram, telex, facsimile, electronic 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 his 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 Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company will comply with the applicable securities

laws and regulations and will be deemed not to have breached their obligations under this Section 4.14 by virtue of such compliance.

(b) Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company will, on the Change of Control Purchase Date:

(1) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

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

The Paying Agent will promptly deliver 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, make such payment through the facilities of the Depositary), and the Trustee will promptly deliver (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 publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

(c) The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control Triggering Event, 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, on and after the relevant purchase date, has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer.

(d) Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditioned upon the consummation of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event at the time the Change of Control Offer is made.

(e) In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer or an Alternate Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company as described above) purchases all of the Notes held by such holders, the Company will have the right, upon not less than 10 nor more than 60 days prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer, 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 the date of redemption (or, in the case of an Alternate Offer, at the purchase price paid in accordance with the terms of such Alternate Offer, plus, to the extent not included in the terms of such Alternate Offer, accrued and unpaid interest, if any, on the Notes that remain outstanding, to the date of redemption), in each case subject to the right of holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

(f) The provisions hereunder relative to the Company’s obligation to make an offer to repurchase the Notes as a result of a Change of Control Triggering Event may be amended, waived, modified or terminated with the consent of the Holders of a majority in principal amount of the Notes (including, without limitation, Additional Notes, if any) then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) prior to the occurrence of such Change of Control Triggering Event.

Section 4.15 Additional Note Guarantees.

If, after the Issue Date, any Restricted Subsidiary of the Company (including any Subsidiary acquired or created after the Issue Date) that is a Domestic Subsidiary and is not already a Guarantor (1) is a Wholly-Owned Subsidiary that guarantees any Capital Markets Indebtedness of the Company or any Guarantor or (2) is an obligor with respect to any Indebtedness of the Company under any Debt Facility permitted to be incurred pursuant to Section 4.09(b)(1), in each case, having an aggregate principal amount outstanding in excess of $12.5 million or, in the aggregate, in excess of $25.0 million, then, in either case, that Restricted Subsidiary will become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering an Officer’s Certificate and an Opinion of Counsel satisfactory to the Trustee, in each case within 30 Business Days after the date that Subsidiary guaranteed or became obligated with respect to such Indebtedness.

Section 4.16 Designation of Restricted and Unrestricted Subsidiaries.

Except during any period that certain covenants have been suspended pursuant to Section 4.17 hereof, the Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if (a) no Default or Event of Default shall have occurred and be continuing immediately prior to such designation or would occur as a result thereof and (b) such Subsidiary (i) does not own any Equity Interests or Indebtedness of the Company or any Restricted Subsidiary (other than Indebtedness to be repaid or Guarantees to be released concurrently with such designation) and (ii) is not liable (as a guarantor or otherwise) with respect to any Indebtedness in connection with which the holder of such Indebtedness has recourse to any of the assets of the Company or any Restricted Subsidiary, other than (A) Indebtedness to be repaid or Guarantees to be released concurrently with such designation, (B) liability arising out of pledges of Equity Interests in such Unrestricted Subsidiary and (C) Customary Recourse Exceptions. If a Restricted Subsidiary 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 an Investment made as of the time of the designation that must either reduce the amount available for Restricted Payments under Section 4.07 hereof or represent an Investment permitted under one or more clauses of such covenant or 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 the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

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 of the Company authorizing such designation and an Officer’s Certificate certifying that such designation complies with the preceding conditions and is permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the requirements set forth in clause (b) of the preceding paragraph or in clauses (1)-(3) of the definition of the term “Unrestricted Subsidiary,” it will thereafter cease to be an Unrestricted Subsidiary for purposes hereof and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, 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.

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: (a) 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 (b) no Default or Event of Default would be in existence following such designation.

Section 4.17 Covenant Suspension.

(a) If on any date following the Issue Date (i) the Notes are assigned an Investment Grade rating from two of three Rating Agencies; and (ii) no Default or Event of Default shall have occurred and be continuing, then, upon the Company’s delivery of notice of such events to the Trustee (the “Suspension Date”), Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.15 (but only with respect to any Person that is required to become a Guarantor after the date of the commencement of the applicable Suspension Date), 4.16 and 5.01(a)(4) of this Indenture will be suspended and no Default or Event of Default shall result from any failure to comply with any of the provisions of such Sections.

(b) After the Suspension Date, the Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries.

(c) Notwithstanding the foregoing, if the rating assigned by at least two of the Rating Agencies should subsequently decline to below Baa3 or BBB-, respectively, the foregoing covenants will be reinstituted as of and from the date of such rating decline. Calculations under the reinstated Section 4.07 hereof will be made as if Section 4.07 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.

(d) The Trustee shall not have any liability or responsibility with respect to, or obligation or duty to monitor, determine or inquire (i) as to whether or not the rating of the Notes has been adjusted, or (ii) as to whether or not an event has occurred or is continuing resulting in the suspension or reinstatement of the covenants pursuant to this Section 4.17. The Trustee will have no obligation to notify the Holders of Notes of the occurrence of such suspension or reinstitution.

(2) the entity so formed by or resulting from such reorganization is an entity organized or existing under the laws of the United States, any state thereof or the District of Columbia;

(3) the entity so formed by or resulting from such reorganization assumes all the obligations of the Company under the Notes and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee;

(4) immediately after such reorganization no Default or Event of Default exists; and

(5) such reorganization is not adverse to the Holders or Beneficial Owners of the Notes (for purposes of this clause (5) it is stipulated that such reorganization shall not be considered adverse to the Holders or Beneficial Owners of the Notes solely because the successor or survivor of such reorganization (a) is subject to federal or state income taxation as an entity or (b) is considered to be an “includible corporation” of an affiliated group of corporations within the meaning of Section 1504(b) of the Code or any similar state or local law).

after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions hereof referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company hereunder with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of, premium on, if any, and interest, if any, on, the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

(B) results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more; provided, however, if, prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid in full, any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(7) failure by the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary of the Company, or any group of the Company’s Restricted Subsidiaries that taken as a whole would constitute a Significant Subsidiary of the Company, to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed, for a period of 60 consecutive days;

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders of all the Notes, rescind an acceleration (other than an acceleration under the first sentence of this Section 6.02) and its consequences hereunder, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, or interest, if any, on the Notes that has become due solely because of the acceleration) have been cured or waived.

Section 6.03 Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium on, if any, or interest, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture, if the rescission would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Notes (including in connection with an offer to purchase); provided, however, that, subject to Section 6.02, the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose hereof; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

Section 6.06 Limitation on Suits.

No Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

(1) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and

(5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision hereof, the right of any Holder of a Note to receive payment of the principal and interest on such Note, on or after the respective due dates expressed in the Note, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium on, if any, and interest, if any, remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, 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 of Notes pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

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

Except in the case of an Event of Default in payment of principal of, premium on, if any, or interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Compensation and Indemnity.

(a) The Company will pay to the Trustee from time to time reasonable compensation for its acceptance hereof and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust.

The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

Such Lien will survive the satisfaction and discharge hereof.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

ARTICLE 8
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time, at the option of the Board of Directors of the Company evidenced by a resolution set forth in an Officer’s Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

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

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

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

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and

(4) this Article 8.

Subject to compliance with this Article 8, the Company may exercise their option under this Section 8.02 notwithstanding the prior exercise of their option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof and clause (a)(4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5), (6), (7) and (10) hereof will not constitute Events of Default.

(3) in the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants or other Person that rendered the opinion delivered under Section 8.04(1) hereof expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium on, if any, or interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as Trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which

102

will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations hereunder and under the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium on, if any, or interest, if any, on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

(a) Notwithstanding Section 9.02 hereof, without the consent of any Holder of Notes, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees:

(1) to cure any ambiguity, omission, mistake, defect or inconsistency;

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Company’s or a Guarantor’s obligations to holders of Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of such Company’s or such Guarantor’s assets, as applicable;

(4) to make any change that would provide any additional rights or benefits to the holders of Notes or that does not adversely affect the legal rights hereunder of any Holder;

(5) to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of notes” in the Offering Memorandum to the extent that such provision in the “Description of notes” was intended to set forth, verbatim or in substance, a provision of this Indenture, the Notes or the Note Guarantees (which intent will be certified to the Trustee in an Officer’s Certificate);

103

(6) to provide for the issuance of Additional Notes in accordance with the limitations set forth herein;

(7) to secure the Notes or the Note Guarantees pursuant to the requirements of Section 4.12;

(8) to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided herein;

(9) to evidence or provide for the acceptance of appointment hereunder of a successor Trustee; or

(10) to provide for the consummation of any transaction permitted by Section 5.01 hereof.

Upon the request of the Company authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, subject to Section 9.05, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms hereof and to make any further appropriate agreements and stipulations that may be therein contained.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Sections 3.11, 4.10 and 4.14 hereof) and the Notes and the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, on, or interest, if any, on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Sections 2.08 and 2.09 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, subject to Section 9.05, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture.

104

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail (or when the Notes are represented by Global Notes, send electronically pursuant to the Applicable Procedures of the Depositary) to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to give such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption or repurchase of the Notes (except those provisions relating to Section 3.11, Section 4.10 or Section 4.14, or the minimum notice provisions under Section 3.03);

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(4) waive a Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in money other than that stated in the Notes;

(6) make any change in the provisions hereof relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, if any, on, or interest, if any, on, the Notes (other than as permitted by clause (2) above or clause (7) below);

(7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Section 4.10 or Section 4.14);

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms hereof; or

105

(9) make any change in the preceding amendment, supplement and waiver provisions.

Section 9.03 Revocation and Effect of Consents.

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. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.04 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9, but the Trustee will not be obligated to enter into any such amendment or supplement that affects the rights, duties, liabilities or immunities of the Trustee hereunder or otherwise. The Company may not sign an amended or supplemental indenture under Section 9.02 hereof until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted hereby.

ARTICLE 10
NOTE GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

106

(1) the principal of, premium on, if any, and interest, if any, on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest, if any, on, the Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will jointly and severally be obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance that 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, notice of acceleration, notice of intent to accelerate and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Notes, the Guarantors will have the right to seek

107

contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and, by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor (if applicable) in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee.

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

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

If an Officer whose signature is on this Indenture or on a notation of Note Guarantee no longer holds that office at the time the Trustee or authenticating agent authenticates the Note on which a notation of Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth herein on behalf of the Guarantors.

In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Subsidiary after the Issue Date, if required by Section 4.15 hereof, the Company will cause such Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 10, to the extent applicable.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Unless such sale or other disposition or consolidation or merger or a contemporaneous event or circumstance, or a series of contemporaneous events or circumstances, results in the release of the Note Guarantee of such Guarantor pursuant to and in compliance with the terms of this Indenture, a Guarantor may not sell or otherwise dispose of, in one or more related

108

transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

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

(2) either:

(a) such Guarantor is the surviving entity; or

(b) subject to Section 10.05 hereof, the Person acquiring the properties or assets in any such sale 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 substantially in the form of Exhibit E hereto.

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 and the due and punctual performance of all of the covenants and conditions hereof to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit hereunder as the Note Guarantees theretofore and thereafter issued in accordance with the terms hereof as though all of such Note Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (2)(a) and (b) above, nothing contained herein or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05 Releases.

(a) The Note Guarantee of a Guarantor will be automatically released:

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor, including 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 4.10 hereof;

109

(2) in connection with any sale or other disposition of the Capital Stock of that Guarantor or of a parent entity of that Guarantor (if such parent entity is a Restricted Subsidiary of the Company), including 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 4.10 hereof and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;

(3) if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions hereof;

(4) upon Legal Defeasance, Covenant Defeasance or satisfaction and discharge hereof as provided in Article 8 and Article 11 hereof;

(5) at such time as such Guarantor ceases both (a) to Guarantee any other Capital Markets Indebtedness of the Company or any other Guarantor (except as a result of payment under any such other Guarantee) and (b) to be an obligor with respect to any Indebtedness under any Debt Facility, in each case, that resulted in the creation of such Guarantee;

(6) upon the liquidation or dissolution of such Guarantor, if no Default or Event of Default has occurred that is continuing; or

(7) upon such Guarantor consolidating with, merging into or transferring all of its properties or assets to the Company or another Guarantor, and as a result of, or in connection with, such transaction under this clause (7), such Guarantor dissolving or otherwise ceasing to exist.

(b) Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium on, if any, and interest, if any, on, the Notes and for the other obligations of any Guarantor hereunder as provided in this Article 10.

(c) Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that any of the conditions in Section 10.05(a) hereof has occurred, the Trustee shall execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Note Guarantee and this Indenture.

110

ARTICLE 11
SATISFACTION AND DISCHARGE.

Section 11.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified herein), when:

(1) either:

(a) 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

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the sending 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 (in the case of Government Securities or a combination of cash in U.S. dollars and Government Securities, (x) in the opinion of a nationally recognized firm of independent public accountants or a nationally recognized investment banking firm or (y) if no such opinion in the immediately preceding clause (x) can be reasonably obtained, in the opinion of the chief financial officer of the Company), 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, if any, on, the Notes to the date of Stated Maturity or redemption;

(2) in respect of clause (1)(b), no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or 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 material agreement or 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);

(3) the Company has paid or caused to be paid all other sums payable by it hereunder; and

111

(4) the Company has delivered irrevocable instructions to the Trustee hereunder to apply the deposited money toward the payment of the Notes at Stated Maturity or on the redemption date, as the case may be.

In addition, the Company must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge hereof, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.06 hereof, that, by their terms, survive the satisfaction and discharge hereof.

Section 11.02 Application of Trust Money.

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

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations hereunder and under the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium on, if any, or interest, if any, on, any Notes because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST. Oasis Petroleum Inc., a Delaware corporation (the “Company”) promises to pay or cause to be paid interest on the principal amount of this Note at 6.375% per annum. The Company will pay interest, if any, semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be [ ], 20[ ]. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; and it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the Company, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest, if any, on all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(3) PAYING AGENT AND REGISTRAR. Initially, Regions Bank, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change the

Paying Agent or Registrar without prior notice to the Holders of the Notes. The Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

(4) INDENTURE. The Company issued the Notes under an Indenture dated as of June 9, 2021 (as such may be amended or supplemented from time to time, the “Indenture”) among the Company, the Guarantor and the Trustee. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) OPTIONAL REDEMPTION.

(a) Except pursuant to the following paragraphs and as set forth in Section 4.14(e) of the Indenture, the Notes will not be redeemable at the Company’s option.

(b) At any time prior to June 1, 2023, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount of Notes issued under the Indenture at a redemption price equal to 106.375% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided that:

(i) at least 60% of the aggregate principal amount of the Notes (including Additional Notes, if any) originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

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

(c) At any time prior to June 1, 2023, the Company may on any one or more occasions redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date.

(d) On or after June 1, 2023, the Company may on any one or more occasions redeem all or a part of the Notes at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, if redeemed during the twelve-month period beginning on June 1 of the years indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date:


Year			Percentage
2023			103.188%
2024			101.594%
2025 and thereafter			100.000%

Unless the Company defaults in the payment of the redemption price, or the redemption is subject to satisfaction of one or more conditions precedent and such conditions precedent are not satisfied, the Notes will become due and payable and interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(6) SPECIAL MANDATORY REDEMPTION. In the event that (a) the Acquisition is not consummated on or prior to September 27, 2021 (or such later date that is the “Outside Date” as defined in and under the Acquisition Agreement) or (b) at any time prior to September 27, 2021 (or such later date that is the “Outside Date” as defined in and under the Acquisition Agreement), the Acquisition Agreement is terminated without the Acquisition being consummated (any such event being a “Special Mandatory Redemption Event”), the Company will redeem all of the Notes (the “Special Mandatory Redemption”), at a price equal to 100% of the issue price of the Notes plus accrued and unpaid interest to, but excluding, the date of redemption date (the “Special Mandatory Redemption Price”). For purposes of the foregoing, the Acquisition will be deemed consummated if the closing under the Acquisition Agreement occurs, including after giving effect to any amendments to the Acquisition Agreement or waivers thereunder acceptable to the Company.

Upon the consummation of the Acquisition, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

(7) MANDATORY REDEMPTION. Except as required by Section 6 hereof, the Company will not be required to make any mandatory redemption or sinking fund payments with respect to the Notes. The Company may at any time and from time to time purchase Notes in the open market or otherwise, in each case without any restriction hereunder.

(8) REPURCHASE AT THE OPTION OF HOLDER.

(a) If a Change of Control Triggering Event occurs, each Holder of Notes will have the right to require the Company 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 pursuant to a Change of Control Offer on the terms set forth in the Indenture. In the Change of Control Offer, the Company will offer a payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase, 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 Triggering Event, the Company will deliver a notice to each Holder describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes properly tendered prior to the expiration date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required by the Indenture and described in such notice. The Company will not be required to make a Change of Control Offer if notice of redemption has been given pursuant to Section 3.03 of the Indenture.

(b) If the Company fails to apply the Net Proceeds from Asset Sales in the manner specified in the Indenture within 365 days after the receipt of such Net Proceeds, any Net Proceeds not so applied will constitute Excess Proceeds. Within 30 days of the aggregate amount of Excess Proceeds exceeding $50.0 million, the Company will make an Asset Sale Offer to all Holders of Notes and all Holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase, prepay or redeem 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 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 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 the aggregate principal amount of Notes and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased, prepaid or redeemed on a pro rata basis (except that any Notes represented by a Global Note shall be selected by such method as the Depositary 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 or applicable stock exchange or depositary requirements), based on the principal

amount of Notes and such other pari passu Indebtedness amounts tendered or required to be prepaid or redeemed (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. The Company may satisfy the foregoing obligation with respect to any Excess Proceeds by making an Asset Sale Offer prior to the expiration of the relevant 365-day period or with respect to Excess Proceeds of $50.0 million or less. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

(9) NOTICE OF REDEMPTION. At least 10 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail (or when the Notes are represented by Global Notes, sent electronically pursuant to the Applicable Procedures of the Depositary), a notice of redemption to each Holder whose Notes are to be redeemed, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Articles 8 or 11 thereof. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased.

(10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any transfer taxes or similar governmental charge payable in connection therewith. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 10 days before a selection of Notes to be redeemed or during the period between a record date and the next succeeding Interest Payment Date.

(11) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as the owner of it for all purposes. Only registered Holders have rights under the Indenture.

(12) AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Guarantees or the Notes may be amended or supplemented as provided in the Indenture.

(13) DEFAULTS AND REMEDIES. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. Upon the occurrence of an Event of Default, the rights and obligations of the Company, the Guarantors, the Trustee and the Holders shall be as set forth in the applicable provisions of the Indenture.

(14) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

(15) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or unitholder or other owner of any Capital Stock of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

(16) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(17) ABBREVIATIONS. 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).

(18) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

(19) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE GUARANTEES 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 will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
