Section 2.2 Execution and Authentication

An Officer shall sign the Securities for the Company by manual, facsimile or electronically transmitted signature. One Officer shall sign each notation of Subsidiary Guarantee for each Guarantor by manual, facsimile or electronically transmitted signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture.

The Trustee shall authenticate and deliver: (i) 2021 Securities for original issue in an aggregate principal amount of $400,000,000 on the Issue Date, (ii) 2024 Securities for original issue in an aggregate amount of $400,000,000 on the Issue Date, and (iii) if and when issued, Additional Securities (which may be issued in either a registered or a private offering under the Securities Act), in each case upon a Company Order. Such Company Order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and whether the Securities are to be in global or definitive form and whether they are to bear the Private Placement Legend. The Company may issue Additional Securities under this Indenture subsequent to the Issue Date, subject to Section 4.3 of this Indenture.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

Section 2.3 Registrar and Paying Agent

The Company shall at all times maintain in the continental United States an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”), and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have 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 such additional paying agent. The Company will give prompt written notice to the Trustee of any such co-registrar or additional paying agents and of any change in the name or address of any such Registrar or Paying Agent.

The Company or any of its Subsidiaries may act as Paying Agent, subject to the provisions of this Section 2.3 and Section 4.14. Any Paying Agent or Registrar may resign as such upon 30 days’ prior written notice to the Company and the Trustee; upon resignation of any Paying Agent or Registrar, the Company shall appoint a successor Paying Agent or Registrar, as the

Active 15472687    39

US 2583278v.8

case may be, complying with the requirements of this Section 2.3, no later than 30 days thereafter and shall provide notice to the Trustee of such successor Paying Agent or Registrar.

If at any time there shall be Securities outstanding that are not Global Securities and there shall be no Paying Agent with an office or agency in the City of New York, State of New York, where the Securities may be presented or surrendered for payment, the Company shall forthwith designate such a Paying Agent in order that such Securities shall at all times be payable in the City of New York, the State of New York.

The Company initially appoints Computershare Trust Company, N.A. as Registrar and Paying Agent for the Securities.

The immunities, protections and exculpations available to the Trustee under this Indenture shall also be available to each Agent, and the Company’s obligations under Section 7.7 to compensate and indemnify the Trustee shall extend likewise to each Agent.

Section 2.4 Paying Agent to Hold Money in Trust

By at least 11:00 a.m. (New York City time) on the date on which any principal, premium, if any, or interest on any Security is due and payable, the Company shall deposit with the Paying Agent in immediately available funds a sum sufficient to pay such principal, premium, if any, and interest when due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal, premium, if any, and interest (if any) on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee.

Section 2.5 Holder Lists

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least seven (7) 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 Holders.

(2)there has occurred and is continuing an Event of Default and the Depositary notifies the Company and the Trustee of its decision to exchange the Global Securities for Definitive Securities; provided that in no event shall the Regulation S Global Security be exchanged by the Company for Definitive Securities prior to the expiration of the Restricted Period.

Upon the occurrence of either of the preceding events in (1) or (2) above, Definitive Securities shall be issued in such names as the Depositary shall instruct the Company, the Trustee and the Registrar. Global Securities also may be exchanged or replaced, in whole or in part, as provided in Section 2.7 hereof. Every Security authenticated and delivered in exchange for, or in lieu of, a Global Security or any portion thereof, pursuant to this Section 2.6 or Section 2.7 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Security. A Global Security may not be exchanged for another Security other than as provided in this Section 2.6(a); however, beneficial interests in a Global Security may be transferred and exchanged as provided in Section 2.6(b), (c) or (f) hereof.

(b)Transfer and Exchange of Beneficial Interests in the Global Securities.

Beneficial interests in such Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in the preceding sentence of this Section 2.6(b)(1).

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Securities contained in this Indenture, the Securities or otherwise applicable under the Securities Act, the principal amount of the relevant Global Security(s) shall be adjusted pursuant to Section 2.6(h) hereof.

(3)Transfer of Beneficial Interests to Another Restricted Global Security. A beneficial interest in any Restricted Global Security may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Security if the transfer complies with the requirements of Section 2.6(b)(2) above and the Registrar receives the following:

(A)if the transferee will take delivery in the form of a beneficial interest in the 144A Global Security, then the transferor must deliver a certificate in the form of Exhibit C hereto, including the certifications in item (1) thereof; and

(B)if the transferee will take delivery in the form of a beneficial interest in the Regulation S Global Security, then the transferor must deliver a certificate in the form of Exhibit C hereto, including the certifications in item (2) thereof, and if such transfer occurs prior to the expiration of the Restricted Period, then the transferee must hold such beneficial interest through either Euroclear or Clearstream (as Indirect Participants in the Depositary).

If any such transfer is effected at a time when an Unrestricted Global Security has not yet been issued, the Company shall issue and, upon receipt of a Company Order in accordance with Section 2.2 hereof, the Trustee shall authenticate one or more Unrestricted Global Securities in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred.

The Trustee shall deliver such Definitive Securities to the Persons in whose names such Securities are so registered. Any Definitive Security issued in exchange for a beneficial interest in a Restricted Global Security pursuant to this Section 2.6(c)(1) shall bear the Private Placement Legend and shall be subject to all restrictions on transfer contained therein. Notwithstanding Sections 2.6(c)(1)(A) and (C) hereof, a beneficial interest in the Regulation S Global Security may not be exchanged for a Definitive Security or transferred to a Person who takes delivery thereof in the form of a Definitive Security prior to the expiration of the Restricted Period, except in the case of a transfer pursuant to an exemption from the registration requirements of the Securities Act other than Rule 903 or Rule 904.

(2)Beneficial Interests in Restricted Global Securities to Unrestricted Definitive Securities. A holder of a beneficial interest in a Restricted Global Security may exchange such beneficial interest for an Unrestricted Definitive Security or may transfer such beneficial interest to a Person who takes delivery thereof in the form of an Unrestricted Definitive Security, in each case only pursuant to Section 2.6(a) and only if the Registrar receives the following:

(3)    Beneficial Interests in Unrestricted Global Securities to Unrestricted Definitive Securities. If any holder of a beneficial interest in an Unrestricted Global Security proposes to exchange such beneficial interest for a Definitive Security or to transfer such beneficial interest

Active 15472687    44

(9)None of the Trustee or any Agent shall have any responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of optional redemption) or the payment of any amount, under or with respect to such Securities. None of the Trustee or any Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.7 Replacement Securities

If any mutilated Security is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, the Company will issue and the Trustee, upon receipt of a Company Order conforming to Section 2.2 hereof, will authenticate a replacement Security of like tenor and principal amount if the Trustee’s and the Company’s reasonable requirements are met. 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 other Agent and any Authenticating

Active 15472687    51

US 2583278v.8

Agent from any loss that any of them may suffer if a Security is replaced. The Company may charge for its expenses (including any tax or charge that may be imposed in connection therewith and the fees and expenses of the Trustee) in replacing a Security.

Every replacement Security is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Securities duly issued hereunder, provided it is held by a protected purchaser within the meaning of the Uniform Commercial Code.

Notwithstanding any other provision of this Section, rather than authenticating and delivering a replacement Security for a mutilated, destroyed, loss or stolen Security which has been redeemed or the principal of which has matured, the Company or the Paying Agent may make payment of the amount due on such security to the Holder upon receipt of the above-described indemnity bond.

Section 2.8 Outstanding Securities

The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 11.6 hereof, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

If the principal amount of any Security is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

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

Section 2.9 Temporary Securities

Until Definitive Securities are ready for delivery, the Company may prepare and the Trustee shall, upon receipt of a Company Order, authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate Definitive Securities in exchange for temporary Securities. Holders of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a holder of Definitive Securities.

Section 2.10 Cancellation

The Company at any time may deliver Securities to the Trustee or any Registrar for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee or the Registrar (and no one else) shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment, replacement or cancellation and deliver a certificate of such destruction to the Company (provided that the Trustee or such Registrar shall deliver a copy of such cancelled Security to the Company upon request prior to destruction). The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee or the Registrar for cancellation.

Section 2.11 Defaulted Interest

If the Company defaults in a payment of interest (“Defaulted Interest”) on the Securities, the Company shall pay Defaulted Interest (as provided in Section 4.1) in any lawful manner. The Company may pay the Defaulted Interest to the Persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date, which special record date shall not be less than 10 days prior to the payment date for such Defaulted Interest and the Company, or at the Company’s request, the Trustee, shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of Defaulted Interest to be paid. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Section 2.11.

Section 2.12 CUSIP Numbers

The Company in issuing the Securities may use “CUSIP,” “ISIN” or similar numbers (if then generally in use) and, if so, the Trustee shall use such numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 3.2 Selection of Securities to Be Redeemed

The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than U.S.$2,000. Securities and portions of them the Trustee selects shall be in minimum amounts of U.S.$2,000 or a whole multiple of U.S.$1,000 in excess thereof.

Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

Section 3.5 Deposit of Redemption Price

(c)For purposes of determining compliance with this Section 4.3:

(1)in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (17) of Section 4.3(b), or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its incurrence and, subject to clause (2) below, may later reclassify (based on circumstances existing on the date of such reclassification) such items of Indebtedness (or any portion thereof), in any manner that complies with this covenant, and only be required to include the amount and type of such Indebtedness in one of such clauses or may include the amount and type of such Indebtedness partially in one such clause and partially in one or more other such clauses;

(2)all Indebtedness outstanding on the Effective Date under the Credit Facilities shall be deemed initially incurred under clause (1) of Section 4.3(b) and not Section 4.3(a) or clause (2) of Section 4.3(b), and the Company shall not be entitled to reclassify such Indebtedness;

(3)Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(4)if obligations in respect of letters of credit are incurred pursuant to the Credit Facility and are being treated as incurred pursuant to clause (1) of the second paragraph above and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(5)the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP;

(6)Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary shall be deemed to have been incurred by the Company and the Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary;

(7)for the avoidance of doubt, any Permitted Refinancing Indebtedness incurred to refund, refinance, replace, defease, discharge, or otherwise retire for value Indebtedness incurred pursuant to any provision in the definition of Permitted Indebtedness that is limited by a percentage of ACNTA of the Company may be incurred pursuant to such provision, even if such refunding, refinancing, replacing, defeasing, discharging, or retiring Indebtedness could not be itself incurred pursuant to such provision at such time; and

(8)the accrual of interest or dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred equity as Indebtedness due to a change in accounting principles, the payment of dividends on Disqualified Stock or preferred equity in the form of additional shares of the same class of Disqualified Stock or preferred equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred equity for purposes of this covenant; provided, in each such case (other than preferred

Active 15472687    63

US 2583278v.8

stock that is not Disqualified Stock), that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued.

(d)For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a non-U.S. currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any of its Restricted Subsidiaries may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities other than cash that are required to be valued by this covenant will be determined, in the case of amounts in excess of U.S.$20.0 million, by an Officer of the Company and, in the case of amounts in excess of U.S.$50.0 million, by the Board of Directors of the Company whose Board Resolution with respect thereto will be delivered to the Trustee; provided that the Fair Market Value of any publicly

Active 15472687    68

US 2583278v.8

traded securities required to be valued by this covenant will be determined by the Company in good faith based on the trading price of such securities and no resolution related to such determination shall be required.

For purposes of determining compliance with this Section 4.4, if a Restricted Payment (or portion thereof) meets the criteria of more than one of the types of Restricted Payments described in clauses (1)-(12) above or one or more clauses of the definition of Permitted Investments (or portions of any of the foregoing) or pursuant to clause (a) or (b) of this Section 4.4, the Company, in its sole discretion, may order and classify, and subsequently reorder and reclassify (based on circumstances existing at the time of such reorder or reclassification), such Restricted Payment (or portion thereof) in any manner in compliance with this covenant.

Section 4.5 Liens

The Company will not, and will not permit any of its Restricted Subsidiaries to create, incur, assume or suffer to exist any Lien (each, an “Initial Lien”) on any property or asset now owned or hereafter acquired, except Permitted Liens, to secure: (a) any Indebtedness of the Company unless prior to, or contemporaneously therewith, the Securities are equally and ratably secured for so long as such other Indebtedness is so secured; or (b) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantee of such Guarantor is equally and ratably secured for so long as such other Indebtedness is so secured; provided, however, that if such Indebtedness is expressly subordinated to the Securities or a Subsidiary Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Securities or such Subsidiary Guarantee, as the case may be, with the same relative priority as such Indebtedness has with respect to the Securities or such Subsidiary Guarantee.

Any Lien created for the benefit of the Holders of the Securities pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount (as described in the following sentence) of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest or dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the payment of dividends on Disqualified Stock or preferred stock in the form of additional shares of the same class of Disqualified Stock or preferred stock, and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rates or currency values or increases in the value of property securing Indebtedness described in the definition of “Indebtedness”.

Section 4.6 Dividend and Other Payment Restrictions Affecting Subsidiaries

US 2583278v.8

(1)pay dividends or make any other distributions on its Capital Stock to the Company or any of the Company’s Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of the Company’s Restricted Subsidiaries (it being understood that the priority of any preferred stock in receiving dividends, distributions or liquidating distributions prior to dividends, distributions or liquidating distributions being paid on Capital Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

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

(3)transfer any of its properties or assets to the Company or any of the Company’s Restricted Subsidiaries.

(b)However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(2)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 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 permitted by the terms of this Indenture to be incurred;

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

(5)cash or other deposits, or net worth requirements or similar requirements, imposed by suppliers, landlords or customers or required by insurance, security or bonding companies, or restrictions on cash or other deposits by parties under agreements entered into in the ordinary course of the Oil and Gas Business of the types described in the definition of Permitted Business Investments;

(6)any applicable law, rule, regulation, order, approval, license, permit or similar restriction;

(8)any encumbrance or restriction contained in the terms of any Indebtedness or Capital Stock permitted to be incurred under this Indenture or any agreement pursuant to which such Indebtedness was incurred if either (x) in the case of Indebtedness, the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (y) the Company determines that any such encumbrance or restriction either (i) will not materially affect the Company’s ability to make principal or interest payments on the Securities and such restrictions are not materially less favorable to Holders of Securities than is customary in comparable financings or (ii) are not materially more restrictive, taken as a whole, with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date or those contained in this Indenture or the Credit Agreement, in each case as determined in good faith by the Board of Directors or an Officer of the Company;

(9)encumbrances or restrictions with respect to an Unrestricted Subsidiary entered into before it became a Restricted Subsidiary and not in contemplation of it becoming a Restricted Subsidiary;

Section 4.7 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 the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Equity Interests or other assets issued or sold or otherwise disposed of (which may be determined at the time of entering into any agreement with respect to such Asset Sale); and

(2)(A) at least 75% of the aggregate consideration therefor received by the Company or such Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash, Cash Equivalents or assets of the type referred to in clauses (2), (3) or (4) of Section 4.7(b) below, or any combination of the foregoing (together, “Permitted Consideration”) or (B) the Fair Market Value of all forms of consideration other than Permitted Consideration does not exceed in the aggregate 10% of the ACNTA of the Company at the time when such determination is made. For purposes of this provision, each of the following shall be deemed to be cash:

(A)any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or any Subsidiary Guarantee) that are (i) assumed by the transferee of any such assets pursuant to a novation agreement or similar agreement that releases the Company or such Restricted Subsidiary from further liability or (ii) retired, canceled, or otherwise terminated in connection with such Asset Sale;

(B)with respect to any Asset Sale of properties used or useful in the Oil and Gas Business by the Company or any of its Restricted Subsidiaries where the Company or such Restricted Subsidiary retains an interest in such property, the amount of the costs and expenses of the Company or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto which the transferee (or an Affiliate thereof) agrees to pay;

(C)Indebtedness (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or a Subsidiary Guarantee) of

Active 15472687    72

US 2583278v.8

any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale; provided that the Company and each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale; and

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

(b)Within eighteen months after the date of receipt of any Net Proceeds from an Asset Sale, the Company or a Restricted Subsidiary may apply such Net Proceeds at its option, in any one or more of the following:

(1)to repay, prepay, redeem or repurchase any Indebtedness of the Company or any Restricted Subsidiary (other than Subordinated Indebtedness);

(2)to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, a Company principally engaged in the Oil and Gas Business that will, upon such acquisition, become a Restricted Subsidiary or acquire any minority interest in a Restricted Subsidiary;

(3)to acquire Capital Stock of any Restricted Subsidiary; provided that all the Capital Stock of such Restricted Subsidiary held by the Company or any of its Restricted Subsidiaries shall entitle the Company or such Restricted Subsidiary to not less than a pro rata portion of all dividends or other distributions made by such Restricted Subsidiary upon any of such Capital Stock; or

(4)to make capital expenditures or to acquire properties or assets, in each case that are used or useful in the Oil and Gas Business.

Pending the final application of any such Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(c)Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.7(b) will constitute “Excess Proceeds”. When the aggregate amount of Excess Proceeds exceeds U.S. $25.0 million, within 30 days thereafter the Company will make an offer (the “Asset Sale Offer”) to all Holders of Securities and, to the extent required by the terms thereof, all holders of other Indebtedness that is pari passu in right of payment with the Securities containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Securities and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price with respect to the Securities in any Asset Sale Offer will be equal to 100% of principal amount (or accreted value in the case of any such other pari passu Indebtedness issued with a significant original issue discount) plus accrued and unpaid interest, if any, to, but not including, the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of purchase), and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise

Active 15472687    73

US 2583278v.8

prohibited by this Indenture. If the aggregate principal amount of Securities and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company shall select the Securities and such other pari passu Indebtedness to be purchased on a pro rata basis, on the basis of the aggregate principal amounts (or accreted values) tendered in round denominations (which in the case of the Securities will be minimum denominations of U.S. $2,000 principal amount or multiples of U.S. $1,000 in excess thereof). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. If the Company makes an Asset Sale Offer prior to the deadline referred to in the first sentence of this paragraph with respect to any Net Proceeds, the Company’s obligations with respect to such Net Proceeds under this covenant shall be deemed satisfied after completion of such Asset Sale Offer.

(d)Within 30 days following the date when the Company becomes obligated to make an Asset Sale Offer, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Asset Sale and offering to repurchase Securities on the date (the “Asset Sale Payment Date”) specified in such notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.

(e)On the Asset Sale Payment Date, the Company will, to the extent lawful:

(1)accept for payment all Securities or portions thereof properly tendered pursuant to the Asset Sale Offer, subject to proration based on the amount of Excess Proceeds pursuant to clause (c) above of this Section 4.7;

(2)deposit with the Paying Agent an amount equal to the amount of Excess Proceeds that, after giving effect to proration with holders of pari passu Indebtedness pursuant to clause (c) above of this Section 4.7, is allocable to the Securities or portions thereof so tendered (or, if less, the aggregate Asset Sale Payment for all Securities validly tendered and not withdrawn); and

(3)deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company.

(f)The Paying Agent will promptly mail (or cause to be transferred through the facilities of the Depositary) to each Holder of Securities so tendered and not withdrawn and accepted for payment in accordance with this Section 4.7, the Asset Sale Payment for such tendered Securities, and the Trustee will, upon receipt of a Company Order, promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any, by such Holder; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof.

(g)If the Asset Sale Offer Purchase Date is after the taking of a record of the Holders on a record date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a purchased Security is registered on such record date, and no other interest will be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

Active 15472687    74

US 2583278v.8

(h)The Company will comply with Applicable Securities Legislation and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.7, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

(i)The Company will publicly announce the results of the Asset Sale Offer, on or as soon as practicable, after the date such Asset Sale Offer is completed.

Section 4.8 Transactions With Affiliates

(a)The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an ‘‘Affiliate Transaction”) involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of U.S. $15.0 million, unless:

(1)such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained at the time of such transaction in arm’s-length dealings by the Company or such Restricted Subsidiary with a Person that is not an Affiliate 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 such Restricted Subsidiary from a financial point of view; and

(2)(a) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of U.S. $15.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with the requirements of clause (1) above, and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of U.S. $30.0 million, a majority of the Disinterested Members of the Board of Directors (or, if there is only one Disinterested Member, such Disinterested Member) have determined that the criteria set forth in clause (1) are satisfied with respect to such Affiliate Transaction(s) and have approved such Affiliate Transaction(s), as evidenced by a Board Resolution delivered to the Trustee and certified by an Officers’ Certificate as having been adopted by the Board of Directors.

(b)The following items shall not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.8(a) hereof:

(1)any employment or severance agreement or other employee, consulting service, termination or director-compensation agreement, arrangement or plan, (or any amendment thereto with respect thereto), or indemnification agreements, entered into by the Company or any Restricted Subsidiary with directors, officers and employees of the Company or any Restricted Subsidiary thereof and the payment of compensation (including but not limited

Active 15472687    75

US 2583278v.8

to awards, grants or issuances of securities) to directors, officers and employees of the Company or any Restricted Subsidiary thereof (including amounts paid pursuant to employee benefit plans, employee stock option or similar plans), so long as such agreement or payment is in the ordinary course of business or has been approved by a majority of the Disinterested Members of the Board of Directors (or, if there is only one Disinterested Member, such Disinterested Member);

(2)transactions between or among the Company and/or its Restricted Subsidiaries, and the issuance of Guarantees for the benefit of the Company or any of its Restricted Subsidiaries not otherwise prohibited by this Indenture;

(5)advances to or reimbursement of expenses incurred by officers and employees for moving, entertainment and travel expenses and similar expenditures in the ordinary course of business of the Company;

(6)any transactions undertaken pursuant to any contracts in existence on the Issue Date (as in effect on the Issue Date) and any renewals, replacements or modifications of such contracts (pursuant to new transactions or otherwise) on terms no less favorable to the Holders of the Securities than those in effect on the Issue Date;

(7)(a) guarantees of performance by the Company or any Subsidiary of the Company in the ordinary course of business, except for guarantees of Indebtedness and (b) pledges of Equity Interests of Unrestricted Subsidiaries for the benefit of lenders of Unrestricted Subsidiaries;

(8)in the case of (i) contracts for (A) drilling or other oil-field services or supplies, (B) the sale, storage, gathering or transport of hydrocarbons or (C) the lease or rental of office or storage space or (ii) other operation-type contracts, any such contracts that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and third parties or, if neither the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, that the terms are on the whole not materially less favorable than those that would be reasonably expected to be available from third parties on an arm’s-length basis, as determined in good faith by the Company;

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

(10)any sale or other issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of a capital contribution from, an Affiliate (or a Person that becomes an Affiliate) of the Company;

Active 15472687    76

US 2583278v.8

(13)any transaction between the Company or any Restricted Subsidiary on the one hand and any Person deemed to be an Affiliate solely because a director of such Person is also a director of the company or a Restricted Subsidiary, on the other hand; provided that such director abstains from voting as a director of the Company or the Restricted Subsidiary, as applicable, in connection with the approval of the transaction; and

(14)transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of the business of the Company and its Restricted Subsidiaries and otherwise in compliance with this Indenture; provided that such transactions are on terms substantially similar to those obtained by the Company or any Restricted Subsidiary in similar transactions with third parties or, if neither the Company nor any Restricted Subsidiary has entered into a similar transaction with a third party, that are on the whole not materially less favorable than those that would be reasonably expected to be available from third parties on an arm’s-length basis, as determined in good faith by the Company.

Section 4.9 Additional Subsidiary Guarantees

If, on or after the Effective Date, any Restricted Subsidiary of the Company that is not already a Guarantor guarantees any Indebtedness of the Company or any Guarantor under a Credit Facility, then that Subsidiary will become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit F hereto and delivering it to the Trustee within 30 days of the date on which it guaranteed such Indebtedness together with an Officers’ Certificate and an Opinion of Counsel, each stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The preceding sentence shall not apply to a Restricted Subsidiary of the Company that, when taken together with each other Restricted Subsidiary of the Company that is not a Guarantor solely as a result of this sentence, accounts for less than 1.0% of the Company’s ACNTA as of the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available and less than 1.0% of the consolidated revenue of the Company for the Company’s most recently ended four fiscal quarters for which internal financial statements are available. Any such Restricted Subsidiary that fails to meet the foregoing requirement as of the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available will become a Guarantor by executing a supplemental indenture and delivering it to the Trustee within 30 days of such failure.

Any such Subsidiary Guarantee shall be subject to release pursuant to Section 10.9(b).

Section 4.10 Business Activities

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material in the opinion of the Board of Directors (which opinion shall be reasonable and made in good faith) to the Company and its Restricted Subsidiaries taken as a whole.

Section 4.11 Change of Control

(a)If a Change of Control occurs, each Holder of Securities will have the right to require the Company to repurchase all or any part (equal to U.S.$2,000 or an integral multiple of U.S.$1,000 in excess thereof) of that Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will offer a payment (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Securities to be repurchased plus accrued and unpaid interest thereon, if any, to, but not including, the date of purchase. Except as provided in Section 4.11(g) below, within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Securities on the date specified in such notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.

To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 4.11, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

(b)On the Change of Control Payment Date, the Company will, to the extent lawful:

If the Company or a Guarantor or other applicable withholding agent is obligated to withhold or deduct any amount on account of Taxes from any payment made under or with respect to the Securities, the Company or such Guarantor or applicable withholding agent, as applicable, will:

(1)make such withholding or deduction;

(4)furnish to the Trustee for the benefit of the Holders of the Securities, within 60 days after the date of the payment or remittance of any Taxes is due pursuant to applicable law, certified copies of an official receipt of the relevant government authorities for all amounts deducted or withheld pursuant to applicable law, or if such receipts are not reasonably obtainable, other documentation evidencing the payment by the Company or such Guarantor, as applicable, of those Taxes; and

(5)at least 15 days prior to each date on which any Additional Amounts are payable, deliver to the Trustee an Officers’ Certificate setting forth the calculation of the Additional Amounts to be paid and such other information as the Trustee may request to enable the Trustee to pay such Additional Amounts to Holders of the Securities on the payment date.

(b)Notwithstanding the foregoing, no Additional Amounts will be paid with respect to or in respect of a payment made to or in respect of any Holder in respect of the beneficial owner thereof (an “Excluded Holder”):

(1)with which the Company or such Guarantor does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of making such payment;

(2)that is a “specified shareholder” of the Company for the purposes of subsection 18(5) of the Income Tax Act (Canada) or a person that does not deal at arm’s length with any such specified shareholder;

(3)which is subject to such Taxes by reason of the Holder or the beneficial owner thereof (or a fiduciary, settlor, beneficiary, partner of, member or shareholder of, or possessor of a power over, the relevant Holder, if the relevant Holder is an estate, trust, nominee, partnership, limited liability company or corporation) being a resident, domicile or national of, incorporated in, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some present or former connection with Canada or any province or territory thereof otherwise than by the mere acquisition, holding or disposition of the Securities or the receipt of payments thereunder;

(4)for or on account of any Taxes imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner of the Securities, to the extent it is legally entitled to do so, to complete, execute and deliver to the Company or a Guarantor, as the case may be, any form or document to the extent applicable to such holder or beneficial owner that may be required by law (including any applicable tax treaty) or by reason of the interpretation or administration of such law and which can be completed by such Holder or beneficial owner using commercially reasonable efforts and is reasonably requested in writing to be delivered to the Company or such Guarantor in order to enable the Company or such Guarantor to make

(5)for or on account of any estate, inheritance, gift, sales, transfer, capital gains, excise, personal property or similar tax, assessment or other governmental charge;

(6)for or on account of any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding from payments under or with respect to the Securities (other than taxes payable pursuant to Regulation 803 of the Income Tax Act (Canada), or any similar successor provision);

(7)if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment to the extent that such payment would be required to be included in income under the laws of the relevant taxing jurisdiction for tax purposes, of a beneficiary or settler with respect to the fiduciary, a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settler, partner or beneficial owner been the holder thereof; or

(8)for or on account of any tax, duty, assessment or other charge imposed pursuant to Sections 1471 through 1474 of the United States Internal Revenue Code of 1986, as amended (the “Code”), as of the date of this Indenture (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof, any similar law or regulation adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States with respect to the foregoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code.

(c)Any reference in this Indenture to the payment of principal, premium, if any, interest, purchase price, redemption price or any other amount payable under or with respect to any Security, will be deemed to include the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Company’s and the Guarantors’ obligation to make payments of Additional Amounts will survive any termination of this Indenture or the defeasance of any rights thereunder.

(d)The Company will indemnify and hold harmless each Holder of the Securities (other than an Excluded Holder) and upon written request reimburse each such Holder for the amount of (x) any Taxes so levied or imposed and paid by such Holder as a result of payments made under or with respect to the Securities, and (y) any Taxes levied or imposed and paid by such Holder with respect to any reimbursement under (x) above, but excluding any such Taxes on or computed by reference to such Holder’s net income, revenue, profits, or capital.

(e)The Company will pay any present or future stamp, court, issue, registration, value added, court or documentary taxes or any other excise or property taxes, charges or similar levies that arise in any Specified Tax Jurisdiction from the execution, delivery, enforcement or registration of the Securities, this Indenture or any other document or instrument in relation thereof, or the receipt of any payments with respect to the Securities (each such tax, a “Security Issuance Tax”) and the Company will indemnify each Holder of Securities (other than an Excluded Holder) for any such Security Issuance Taxes paid by such Holder.

(3)failure by the Company to comply with Section 5.1 hereof;

(A)is caused by a failure to pay when due any principal of such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (a “Payment Default”); or

Active 15472687    86

US 2583278v.8

(B)results in the acceleration of such Indebtedness prior to its Stated 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 U.S. $50.0 million or more (the “cross-acceleration provision”); provided, however, that if any such Payment Default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such Payment Default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Securities shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(7)failure by the Company or any of its Restricted Subsidiaries that is also a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary to pay final non-appealable judgments aggregating in excess of U.S. $50.0 million (net of any amounts covered by insurance or a binding indemnity agreement), which judgments are not paid, discharged or stayed for a period of 60 days (the “Judgment Provision”);

(8)any Subsidiary Guarantee of a Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or, except as permitted by this Indenture, shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee (the “Guarantee Default Provision”), in each case with respect to any Guarantor that is also a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary;

(9)(A) the Company or a Significant Subsidiary or a group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(i)commences a voluntary case or proceeding;

(ii)consents to the entry of an order for relief against it in an involuntary case or proceeding in which it is a debtor;

(iii)consents to the appointment of a Custodian of it or for any substantial part of its property;

(iv)makes a general assignment for the benefit of its creditors; or

(v)consents to the institution of a bankruptcy or an insolvency proceeding against it; or takes any comparable action under any foreign laws relating to insolvency; or

(10)failure to redeem the Securities in accordance with Section 3.9.

However, a Default under clauses (4) and (5) of this Section 6.1 will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default (with a copy to the Trustee) and the Company does not cure such Default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

Section 6.2 Acceleration of Maturity; Rescission and Annulment

If an Event of Default (other than an Event of Default described in clause (9) of Section 6.1) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may declare the principal of, and accrued and unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal and accrued and unpaid interest will be due and payable immediately. If an Event of Default described in clause (9) of Section 6.1 above occurs and is continuing, the principal of, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any further action or notice on the part of the Trustee or any Holders. The Holders of a majority in outstanding principal amount of the Securities by notice to the Trustee may on behalf of the Holders of all the Securities rescind any such acceleration with respect to the Securities and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, and interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived.

Section 6.3 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 (if any) or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

Active 15472687    88

US 2583278v.8

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.4 Waiver of Past Defaults

The Holders of a majority in outstanding principal amount of the Securities, by notice to the Trustee may on behalf of the Holders of all the Securities waive an existing Default or Event of Default and its consequences hereunder except a Default or Event of Default in respect of a provision that under Section 9.2 hereof cannot be amended without the consent of each Holder affected. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 6.5 Control by Majority

The Holders of a majority in outstanding principal amount of the Securities (voting as a single class or series) have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.1 hereof, that is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Subject to Section 7.1, prior to taking any action hereunder, the Trustee shall receive indemnification satisfactory to it against all loss, liability and expense caused by taking or not taking such action.

Section 6.6 Limitation on Suits

Except to enforce the right to receive payment of principal, premium (if any) or interest when due, a Holder may not pursue any remedy with respect to this Indenture, the Securities or the Subsidiary Guarantees unless:

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

(2)Holders of at least 25% in outstanding principal amount of the Securities have made a written request to the Trustee to pursue the remedy;

(3)such Holder or Holders have furnished the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(4)the Trustee has not complied with the Holders’ request within 60 days after receipt of the request and the furnishing of security or indemnity; and

Active 15472687    89

US 2583278v.8

(5)the Holders of a majority in outstanding principal amount of the Securities have not given the Trustee a direction that is inconsistent with the request during such 60-day period.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder prejudices the rights of any other Holders or obtains preference or priority over such other Holders).

Section 6.7 Rights of Holders to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.8 Collection Suit by Trustee

The consent of the Holders is not necessary under this Section 9.2 to approve the particular form of any proposed amendment or waiver. It is sufficient if the consent approves the substance of the proposed amendment or waiver.

After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company shall mail to each Holder of Securities affected thereby a notice briefly describing such amendment. The failure to give such notice to any or all Holders, or any defect therein, shall not impair or affect the validity of any amendment, supplement or waiver under this Section 9.2.

Section 9.4 Notation on or Exchange of Securities

If an amendment or supplement changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee, upon receipt of a Company Order, shall authenticate a new Security that reflects the changed terms, but the failure to make the appropriate notation or to issue a new Security shall not affect the validity and effect of such amendment or supplement.

Section 9.5 Trustee to Sign Amendments

The Trustee shall sign any amendment or supplement authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, powers, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment or supplement the Trustee shall receive, and (subject to Section 7.1 hereof) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel, each stating that the execution of such amendment or supplement is authorized or permitted by this Indenture.

ARTICLE XSUBSIDIARY GUARANTEES

Section 10.1 Subsidiary Guarantees

Each Guarantor which is a party hereto or becomes a party hereto by executing and delivering a supplement to this Indenture pursuant to Section 4.9 hereof, jointly and severally, unconditionally Guarantees to each Holder and to the Trustee and its successors and assigns the full and punctual payment of principal of, premium (if any) and interest on the Securities when due, whether at Stated Maturity, or upon redemption, required repurchase pursuant to Section 4.7 or Section 4.11 hereof, acceleration or otherwise, and all other monetary obligations owing by the Company under this Indenture (including obligations owing to the Trustee) and the Securities (all the foregoing being hereinafter collectively called the “Obligations”). The Guarantors further agree that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from the Guarantors, and that the Guarantors will remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

US 2583278v.8

The Guarantors waive presentation to, demand of payment from and protest to the Company of any of the Obligations and also waive notice of protest for nonpayment. The Guarantors waive notice of any Default under the Securities or the Obligations. The obligations of the Guarantors hereunder shall not be affected by: (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension or renewal of any Obligation; (iii) any rescission, waiver, amendment, modification or supplement of any of the terms or provisions of this Indenture (other than this Article X), the Securities or any other agreement; (iv) the release of security, if any, held by any Holder or the Trustee for the Obligations or any of them; (v) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; (vi) any change in the ownership of the Company; or (vii) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Guarantors or would otherwise operate as a discharge of the Guarantors as a matter of law or equity, except for payment of the Securities in full.

The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees herein constitute a guarantee of payment when due (and not a guarantee of collection) and waive any right to require that any resort be had by any Holder or the Trustee to security, if any, held for payment of the Obligations.

The obligations of the Guarantors hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (except to the extent provided in Section 10.2 hereof), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense, setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise.

The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against the Guarantors by virtue hereof, upon the failure of the Company to pay any Obligation when and as the same shall become due, whether at Stated Maturity, upon redemption, required repurchase, acceleration or otherwise, the Guarantors hereby promise to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Obligations, (ii) accrued and unpaid interest on such Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Obligations of the Company to the Holders and the Trustee.

The Guarantors, jointly and severally, agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations may be accelerated as provided in Article VI for the purposes of the Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article VI, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purposes of this Section 10.1.

Active 15472687    103

US 2583278v.8

The Guarantors, jointly and severally, also agree to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.1.

Section 10.2 Limitation on Liability

Each Guarantor, and by its acceptance of Securities, each Holder, hereby confirm that it is the intention of all such parties that the Subsidiary 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 Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each 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 in respect of the obligations of such other Guarantor under this Article X, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

The obligations of a Guarantor incorporated in Luxembourg (each, a “Luxembourg Guarantor”) under this Article X shall at all times be limited to an aggregate amount not exceeding the greater of:

(a)(i) the aggregate of all principal amounts (if any) received by that Luxembourg Guarantor from one or more other members of the group that have been received directly or indirectly from proceeds of the issue of the Securities, plus (ii) 99% of the Luxembourg Guarantor’s own funds (capitaux propres, as referred to in article 34 of the Luxembourg law dated 19 December, 2002 concerning the trade and companies register and the accounting and annual accounts of undertakings, as amended) but adding any debt owed by such Luxembourg Guarantor to any of its direct or indirect shareholders (without any double counting of the amounts referred to under clause (a)(i) above) as reflected in its last annual accounts duly approved and available on the date of guarantee payment under the Guarantee of the Securities.

(b)(i) the aggregate of all principal amounts (if any) received by that Luxembourg Guarantor from one or more other members of the group that have been received directly or indirectly from proceeds of the issue of the Securities; plus (ii) 99% of the Luxembourg Guarantor’s own funds (capitaux propres, as referred to in article 34 of the Luxembourg law dated 19 December, 2002 concerning the trade and companies register and the accounting and annual accounts of undertakings, as amended) but adding any debt owed by such Luxembourg Guarantor to any of its direct or indirect shareholders (without any double counting of the amounts referred to under clause (b)(ii) above) as reflected in its last annual accounts duly approved and available as at the date of the Guarantee of the Securities.

Section 10.3 Execution and Delivery of Subsidiary Guarantee

To evidence its Subsidiary Guarantee set forth in Section 10.1, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by manual, facsimile or electronically transmitted signature by an Officer of such Guarantor on each Security authenticated and delivered by the Trustee and that

Active 15472687    104

US 2583278v.8

this Indenture (or a supplemental indenture substantially in form of Exhibit F hereof) will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.1 will remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Subsidiary Guarantee. If an Officer whose signature is on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Security on which the Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

The delivery of any Security by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

In the event that the Company or any of its Restricted Subsidiaries acquires or creates another Restricted Subsidiary after the Issue Date, the Company will comply with the provisions of Section 4.9 hereof.

Section 10.4 Successors and Assigns

Except as otherwise provided in Section 10.9 hereof, this Article X shall be binding upon the Guarantors and their successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights in accordance with the terms of this Indenture by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture, the Securities and the Subsidiary Guarantees.

Section 10.5 No Waiver

Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article X shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article X at law, in equity, by statute or otherwise.

Section 10.6 Right of Contribution

Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of this Article X. The provisions of this Section 10.6 shall in no respect limit the obligations and liabilities of any Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.

Active 15472687    105

US 2583278v.8

Section 10.7 No Subrogation

Notwithstanding any payment or payments made by any of the Guarantors hereunder, no Guarantor shall be entitled to exercise any rights of subrogation it may have to any of the rights of the Trustee or any Holder against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Obligations.

Section 10.8 Modification

No modification, amendment or waiver of any provision of this Article X, nor the consent to any departure by the Guarantors therefrom, shall in any event be effective unless the same shall be made in accordance with Article IX hereof. No notice to or demand on the Guarantors in any case shall entitle the Guarantors to any other or further notice or demand in the same, similar or other circumstances.

Section 10.9 Merger, Amalgamation, Consolidation or Sale of Assets of a Guarantor; Release of a Guarantor

(a)Except in a transaction resulting in the release of a Subsidiary Guarantee of a Guarantor, the Company shall not permit a Guarantor to sell or otherwise dispose of all or substantially all of its assets, or consolidate or amalgamate with or merge with or into (whether or not such Guarantor is the resulting, transferee or surviving Person), another Person (other than the Company or another Guarantor), unless:

(1)immediately after giving effect to that transaction, no Default or Event of Default shall have occurred and be continuing; and

(2)either (a) the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation, amalgamation or merger (if other than the Guarantor) assumes all the obligations of that Guarantor under its Subsidiary Guarantee pursuant to a supplemental indenture or (b) such transaction complies with Section 4.7.

(b)The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released:

(1)in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger, amalgamation or consolidation), other than to the Company or a Subsidiary, if such transaction as of the time of such disposition complies with Section 4.7 hereof;

US 2583278v.8

(2)in connection with any sale or other disposition of the Capital Stock of a Guarantor (including by way of merger, amalgamation or consolidation) other than to the Company or a Subsidiary, if such transaction as of the time of such disposition complies with Section 4.7 hereof and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of such transaction;

(3)if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the provisions of this Indenture;

(4)if the Company exercises either its legal defeasance option or its covenant defeasance option in accordance with Section 8.1(b) hereof or if it satisfies and discharges this Indenture in accordance with Section 8.1(a) hereof;

(5)unless a Default or Event of Default has occurred and is continuing, at such time as such Guarantor ceases to guarantee any other Indebtedness of the Company or any other Guarantor under a Credit Facility; or

(6)upon the liquidation or dissolution of such Guarantor into the Company or another Guarantor, provided no Default or Event of Default occurs as a result thereof or has occurred or is continuing.

(c)Upon delivery by the Company to the Trustee of an Officers’ Certificate stating that any of the conditions described in clauses (1)-(6) of Section 10.9(b) 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 Subsidiary Guarantee and this Indenture.

(a)Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing, and may be given or obtained in connection with a purchase of, or tender offer or exchange offer for, outstanding Securities; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company if made in the manner provided in this Section 11.16.

(b)The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such witness, notary or officer the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c)Notwithstanding anything to the contrary contained in this Section 11.16, the principal amount and serial numbers of Securities held by any Holder, and the date of holding the same, shall be proved by the register of the Securities maintained by the Registrar as provided in Section 2.3.

(d)If the Company shall solicit from the Holders of the Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at their option, by or pursuant to a resolution of its Board of Directors, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith or the date of the most recent list of Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.5 and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the then outstanding

Active 15472687    111

Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the then outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

(e)Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

(f)Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so itself with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

(g)For purposes of this Indenture, any action by the Holders which may be taken in writing may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

Section 11.17Indemnification for Non-U.S. Dollar Currency Judgments.

(a)The obligations of the Company or any Guarantor to any Holder of Securities or the Trustee shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than United States dollars (the “Agreement Currency”), be discharged only to the extent that on the first Business Day following receipt by such Holder of Securities or the Trustee, as the case may be, of any amount in the Judgment Currency, such Holder of Securities or the Trustee may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency in New York, New York. If the amount of the Agreement Currency that could be so purchased is less than the amount originally to be paid to such Holder of Securities or the Trustee, as the case may be, in the Agreement Currency, the Company and each Guarantor agrees, as a separate obligation and notwithstanding such judgment, to pay to such Holder of Securities or the Trustee, as the case may be, the difference, and if the amount of the Agreement Currency that could be so purchased exceeds the amount originally to be paid to such Holder of Securities or the Trustee, as the case may be, such Holder of Securities or the Trustee, as the case may be, agrees to pay to or for the account of the Company such excess, provided that such Holder of Securities or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a default by the Company or any Guarantor in its obligations in respect of its obligations to pay when due any principal of, or interest, premium, if any, liquidated damages, if any, or Additional Amounts, if any, on the Securities, or any other amounts due under this Indenture or the Guarantees has occurred and is continuing, in which case such excess may be applied by such Holder of Securities or the Trustee, as the case may be, to such payment obligations.

(b)The provisions of this Section 11.17 shall apply irrespective of any indulgence granted to the Company or any Guarantor from time to time and shall continue in full force and effect notwithstanding any payment by or on behalf of the Company or any Guarantor, and any

[BACK OF 2021 SECURITY]BAYTEX ENERGY CORP.5.125% SENIOR NOTE DUE 2021

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

1.    Interest. Baytex Energy Corp., an Alberta Canada corporation (the “Company”), promises to pay interest on the outstanding principal amount of this 2021 Security at the rate of 5.125% per annum. The Company will pay interest 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”), provided, that the first Interest Payment Date shall be December 1, 2014. Interest on the 2021 Securities 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 there is no existing Default in the payment of interest, and if this 2021 Security 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. The Company will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, at the rate then in effect; it will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue instalments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate as on overdue principal. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Solely for the purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which the rate used in such computation is equivalent during any particular period is the rate so used multiplied by a fraction of which: (a) the numerator is the product of: (i) the actual number of days in the calendar year in which such period ends, and (ii) the sum of (A) the product of (x) 30 and (y) the number of complete months elapsed in the relevant period and (B) the number of days elapsed in any incomplete month in the relevant period, and (b) the denominator is the product of (i) 360 and (ii) the actual number of days in the relevant period.

2.    Method of Payment. The Company will pay interest on the 2021 Securities (except Defaulted Interest) to the Persons who are registered Holders of 2021 Securities at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such 2021 Securities are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.11 of the Indenture with respect to Defaulted Interest. The 2021 Securities will be payable as to principal, premium, if any, and interest at the office or agency of the Paying Agent maintained for such purpose, or, at the option of the Company, payment of interest may be made by check mailed by such Paying Agent 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 and interest, and premium, if any, on all Global Securities and all other 2021 Securities, the Holders of which hold at least $5,000,000 aggregate principal amount of the 2021 Securities and have provided wire transfer instructions to the Company and 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. Holders must surrender their 2021 Securities to the Paying Agent to collect payments of principal and premium, if any.
