AMENDMENT NO. 1 TO
EXECUTIVE EMPLOYMENT AGREEMENT
This Amendment No. 1 to Executive Employment Agreement (“Amendment”) is made as of October 11, 2022 between KVH Industries, Inc. a Delaware corporation (the “Company”), and Brent C. Bruun (the “Executive”).
WHEREAS, the Company and the Executive are parties to an Executive Employment Agreement (the “Agreement”) dated as of May 2, 2022; 
WHEREAS, on June 15, 2022, the Executive was appointed President and Chief Executive Officer of the Company; and
WHEREAS, in light of such promotion, the Company and the Executive wish to modify certain terms of the Agreement, including the Executive’s compensation and an extension of the period during which the Executive must continue to remain employed by the Company in order to earn the Retention Bonus (as defined in the Agreement) from December 31, 2022 to December 2023, subject to the terms and conditions of the Agreement,
NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:
1.Defined Terms.  Capitalized terms used but not defined in this Amendment shall have the respective meanings given to them in the Agreement.
2.Increase in Base Salary.  Section 2(a) of the Agreement is hereby amended to insert the following immediately after the first sentence thereof:  “Effective as of July 1, 2022, the Executive’s annual base salary is increased to the rate of $448,360 per year. The amount of the increase in salary for the period beginning July 1, 2022 to the date of this Amendment shall be paid promptly after the date of this Amendment but not before the Company’s next regularly scheduled payroll date.”
3.Increase in Target Bonus Percentage.  Section 2(b) of the Agreement is hereby amended to insert the following sentence immediately after the second sentence thereof: “Effective as of July 1, 2022, the Executive’s target annual incentive compensation shall be eighty percent (80%) of the Executive’s Base Salary.” For avoidance of doubt, the Executive’s target annual incentive compensation shall remain at sixty percent (60%) of the Executive’s Base Salary (as in effect on May 2, 2022) for the period from January 1, 2022 to June 30, 2022.
4.Extension of Retention Date for Retention Bonus.
(a)Section 2(f)(i) of the Agreement is hereby deleted and replaced with the following:
“(i)    If the Executive continues to serve as an employee of the Company from the date hereof through December 31, 2023 (the “Retention Date”), then the Company shall pay the Executive a cash retention bonus (the “Retention Bonus”) in an amount equal to seventy-five percent (75%) of the highest Base Salary in effect for Executive on or before the date Executive becomes entitled to receive the Retention Bonus or the Partial Retention Bonus, such Retention Bonus to be paid within thirty (30) days after the Retention Date in a manner that is consistent with the Company’s usual payroll practices for executive officers. If the Executive continues to serve as an employee of the Company from the date hereof through December 31, 2022, then notwithstanding anything to the 

contrary in any applicable option agreement or other stock-based award agreement, all stock option and other stock-based awards subject to vesting held by the Executive (collectively, the “Equity Awards”) that would otherwise vest in the twelve (12) months after December 31, 2022 (assuming that any performance-based conditions to vesting shall have been satisfied at the target level of performance) shall on December 31, 2022 accelerate and become exercisable or non-forfeitable.
(b)Sections 2(f)(ii) and (iii) of the Agreement are hereby amended to replace the date “December 31, 2022” with the date “December 31, 2023” in each of the four places that such date appears in such Sections.
5.No Other Changes. Except as set forth in this Amendment, the Agreement shall continue in full force and effect.
6.Entire Agreement. This Agreement, as amended by this Amendment, constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements between the parties concerning such subject matter, provided that the Equity Documents shall remain in full force and effect.
7.Counterparts. This Amendment may be executed in any number of counterparts, each of which when so executed and delivered shall be taken to be an original; but such counterparts shall together constitute one and the same document.
8.Sections Applicable to this Amendment.  The provisions of Section 10, Sections 12 through 22 and the first sentence of Section 23 shall apply to this Amendment to the same extent that they apply to the Agreement.

 ARTICLE 2 

THE SECURITIES 

SECTION 2.01 Form and Dating. Provisions relating to the Securities are set forth in the Private Resale Appendix attached hereto (the
“Appendix”), which is hereby incorporated in, and expressly made part of, this Indenture. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix,
which is hereby incorporated in, and expressly made a part of, this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided
that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit 1 are part of the terms
of this Indenture. 
 SECTION 2.02 Execution and Authentication. Two Officers shall sign the Securities for the Company by manual or
facsimile 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
signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 

On the Issue Date, the Trustee authenticated and delivered the Existing Securities, on the Amendment Date, the Trustee shall authenticate and
deliver US$112,000,000 of 12.00% Senior PIK Toggle Notes due 2024 in order to amend and restate, without novation, the Existing Securities and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Additional
Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers. Such 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, in the case of an issuance of Additional Securities pursuant to Section 2.13 hereof after the Amendment Date, shall certify that such issuance is in compliance with
Section 4.05 hereof. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the
Securities. Unless limited by the terms of such appointment, an 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.
An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 
 SECTION 2.03
Registrar and Paying Agent. The Company shall maintain an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co- registrar) where Securities may be
presented for registration of transfer or for exchange (the “Registrar”) and an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Securities may be presented
for payment (the “Paying 

  
 33 

 
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 “Paying Agent” includes any additional paying agent. 
 The Company shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and
address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07 hereof. The Company or any of the
Guarantors may act as Paying Agent, Registrar, co-registrar or transfer agent. 
 The Company initially appoints the Trustee as Registrar
and Paying Agent in connection with the Securities. The Company initially appoints DTC to act as Depositary with respect to the Global Securities. 

SECTION 2.04 Paying Agent to Hold Money in Trust. The Company shall deposit with the Paying Agent a sum sufficient to pay such
principal prior to 10:00 a.m. (New York time) on the date principal and premium, if any, becomes due. The Company shall deposit with the Paying Agent a sum sufficient to pay interest on the day prior to the date such interest becomes due. Principal,
premium, if any, and interest will be considered paid on the date due if the Paying Agent holds (as of 1:00 p.m., New York City time, on the due date) money deposited by the Company in immediately available funds and designated for and sufficient to
pay all principal and premium, if any, and interest, if any, then due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the
Trustee all money held by the Paying Agent for the payment of principal of or interest 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 of the Company 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 to pay all money held by it to the Trustee and to account for any funds disbursed by the
Paying Agent. Upon complying with this Section 2.04, the Paying Agent shall have no further liability for the money delivered to the Trustee. 

SECTION 2.05 Securityholder 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 Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five 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 Securityholders. 

SECTION 2.06 Transfer and Exchange. A holder may transfer or exchange Securities in accordance with the provisions of this Indenture.
The Registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Securities. Holders shall be required to pay all taxes due on transfer. The Company
shall not be required to transfer or exchange any Security selected for redemption. Also, the Company shall not be required to transfer or exchange any Security for a period of 15 days before the mailing of a notice of redemption of the Securities
to be redeemed or between a record date and the next succeeding Interest Payment Date. Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by DTC. 

  
 34 

 SECTION 2.07 Replacement Securities. If a mutilated Security is surrendered to the
Registrar or if the holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the holder satisfies any other reasonable requirements of the Trustee. Such holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the holder for their expenses in replacing a Security. 

Every replacement Security is an additional obligation of the Company. 

SECTION 2.08 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for
those canceled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. 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 2.07 hereof, it ceases to be outstanding unless the Trustee and the Company receive proof
satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code). 

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient
to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and
interest on them ceases to accrue. 
 SECTION 2.09 Temporary Securities. Until definitive Securities are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. 

SECTION 2.10 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities they have redeemed, paid or delivered to the Trustee
for cancellation. 
 SECTION 2.11 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company
shall pay defaulted interest (plus interest on such defaulted interest 

  
 35 

 
to the extent lawful) in any lawful manner at the rate provided in the Securities and Section 4.01 hereof. The Company may pay the defaulted interest at the rate provided in the Securities
and Section 4.01 hereof to the persons who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and, at
least 15 days before any such subsequent record date, shall promptly send to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 

SECTION 2.12 CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common
Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” 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 shall promptly advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or
“Common Code” numbers applicable to the Securities. 
 SECTION 2.13 Issuance of Additional Securities. After the
Amendment Date, the Company shall be entitled, subject to its compliance with Section 4.05 hereof, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Securities authenticated on the Amendment
Date, other than with respect to the date of issuance and the issue price. All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to
purchase. 
 With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an
Officer’s Certificate, a copy of each which shall be delivered to the Trustee, the following information: 
  

	 	(1)	 the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this
Indenture and the provision of Section 4.05 hereof that the Company is relying on to issue such Additional Securities; and 

  

	 	(2)	 the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however,
that if Additional Securities are issued with the same CUSIP number as any other Securities previously issued under this Indenture, then such Additional Securities shall be issued at a price that would not prevent such Additional Securities from
being treated as fungible with such previously-issued Securities for U.S. federal income tax purposes. 

 In connection
with the issuance of Additional Securities, the Trustee shall receive and shall be fully protected in relying on an Opinion of Counsel which shall state: 
  

	 	(1)	 that the form of such Securities has been established by or pursuant to a resolution of the Board of Directors
and in conformity with the provisions of this Indenture; 

  
 36 

	 	(2)	 that the terms of such Securities have been established in conformity with the provisions of this Indenture;
and 

  

	 	(3)	 that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner
and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles. 

SECTION 2.14 Additional Amounts. 

(a) All payments made by or on behalf of the Company under or with respect to the Securities, or by or on behalf of any Guarantor under or with
respect to any Note Guarantee, will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other
liabilities related thereto) (hereinafter referred to as “Taxes”) imposed or levied by or on behalf of: 
  

	 	(1)	 the government of Canada or any province or territory of Canada;

political subdivision or any authority or agency therein or thereof having power to tax (each, a “Relevant Taxing Jurisdiction”); 

unless such Person is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. 

(b) If the Company or any Guarantor (each such Person, a “Payor”) is so required to withhold or deduct any amount for or on
account of Taxes imposed by a Relevant Taxing Jurisdiction from any payment made under or with respect to a Security or any Note Guarantee, such Payor will be required to pay such additional amounts (“Additional Amounts”) as may be
necessary so that the net amount received by a holder or beneficial owner of Securities (including Additional Amounts) after such withholding or deduction will not be less than the amount such holder or beneficial owner of Securities would have
received if such Taxes (including Taxes on any Additional Amounts) had not been withheld or deducted; provided, however, that the foregoing obligations to pay Additional Amounts do not apply to: 

 

	 	(1)	 any Taxes imposed on a payment to any holder or beneficial owner of Securities with which the applicable Payor
does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of the payment; 

  
 37

beneficial holder being a “specified shareholder” of the Company (within the meaning of subsection 18(5) of the Income Tax Act (Canada)) at the time of payment or deemed payment, or by reason of such holder or beneficial holder not dealing
at arm’s length for the purposes of the Income Tax Act (Canada) with a “specified shareholder” of the applicable Payor at the time of payment or deemed payment; 

 

	 	(3)	 any Taxes imposed on a payment by virtue of all or any portion of such payment being deemed to be a dividend
paid pursuant to the Income Tax Act (Canada); 

  

	 	(4)	 any Taxes that would not have been so imposed but for the existence of any present or former connection between
the relevant holder or beneficial owner of Securities and the Relevant Taxing Jurisdiction including, for greater certainty and without limitation, being or having been a citizen, resident or national thereof, or being or having been present or
engaged in a trade or business therein or maintaining a permanent establishment or other physical presence in or otherwise having some connection with the Relevant Taxing Jurisdiction (other than a connection from the mere acquisition, ownership or
holding of such Security or a beneficial interest therein or the enforcement of rights thereunder or the receipt of any payment in respect thereof); 

  

	 	(5)	 any estate, inheritance or gift Tax; 

 

	 	(6)	 any sales, excise, transfer, personal property Tax or similar Tax, assessment or governmental charge, except to
the extent such Tax, assessment or governmental charge is levied or imposed in connection with the execution, delivery, enforcement or registration of the Securities; 

 

	 	(7)	 any deduction or withholding of Taxes on a payment if the payment could have been made without such deduction
or withholding if the beneficiary of the payment had presented the Securities for payment within 30 days after the date on which such payment or such Security became due and payable or the date on which payment thereof is duly provided for,
whichever is later (except to the extent that the holder or beneficial owner would have been entitled to Additional Amounts had the Security been presented on the last day of such 30–day period); 

 

	 	(8)	 any Taxes imposed by reason of the holder’s or beneficial owner’s failure to comply with any
certification, documentation, information or other reporting requirement concerning such holder’s or beneficial owner’s nationality, citizenship, residence, identity or other connection with the Relevant Taxing Jurisdiction if compliance
is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Taxes to which such holder or beneficial owner is entitled;

  
 38 

	 	(9)	 any tax, assessment or other governmental charge which would have been avoided by such holder by presenting the
relevant Security (if presentation is required) to another Paying Agent (if there is one); 

  

	 	(10)	 any Taxes imposed on a payment to a holder of Securities that is a fiduciary or partnership or any other Person
other than the sole beneficial owner of such payment or Securities, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner of such payment or Securities would not have been
entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the actual holder of such Securities; 

  

	 	(11)	 any Taxes imposed directly or indirectly under FATCA; or 

 

	 	(12)	 any combination of any of the above clauses (any such Tax in respect of which Additional Amounts are payable,
an “Indemnified Tax”). 

 (c) The applicable Payor will make any required withholding or deduction and
remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction in accordance with applicable law. The Company will provide the Trustee with official receipts or other documentation evidencing the payment of the Taxes with respect to
which Additional Amounts are paid. 
 (d) If a Payor is or will become obligated to pay Additional Amounts under or with respect to any
payment made on the Securities or a Note Guarantee, at least 30 days prior to the date of such payment (or, if the obligation to pay Additional Amounts arises after the 30th day prior to such date, promptly thereafter), such Payor will deliver to
the Trustee an Officer’s Certificate stating the fact that Additional Amounts will be payable and the amount so payable and such other information necessary to enable the Paying Agent to pay Additional Amounts to holders on the relevant payment
date.

Securities; (2) redemption prices or purchase prices in connection with a redemption or purchase of Securities; (3) interest; or (4) any other amount payable on or with respect to any of the Securities or any Guarantee, such reference
shall be deemed to include payment of Additional Amounts as described under this heading to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. 

(f) The Payor will indemnify and hold harmless a holder of the Securities for the amount of any Indemnified Taxes (including for greater
certainty taxes payable pursuant to Regulation 803 of the Income Tax Regulations (Canada)) levied or imposed and paid by such holder as a result of payments made under or with respect to the Securities or any Guarantee, and with respect to any

documentary taxes or any other excise, property or similar Taxes that arise in any Relevant Taxing Jurisdiction from the execution, delivery, enforcement or registration of the Securities, the Note Guarantees, this Indenture or any other document or
instrument in relation thereto, and each of the Company and the Guarantors will agree to indemnify the holders of Securities for any such amounts (including penalties, interest and other liabilities related thereto) paid by such holders. 

(h) The obligations described in this Section 2.14 will survive any termination, defeasance or discharge of this Indenture and will apply
mutatis mutandis to any jurisdiction in which any successor Person to the Company or any Guarantor is organized or any political subdivision or taxing authority or agency thereof or therein. 

(i) If (i) a Payor becomes, or will become, obligated to pay, on the next date on which any amount may be payable with respect to the
Securities, any Additional Amounts as a result of a change (or a change in legislation proposed by the Minister of Finance of Canada or any similar authority that, if enacted, will be effective prior to the enactment date) in or amendment to the
laws, regulations or rulings of any Relevant Taxing Jurisdiction, or any change in official position regarding the application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which

Amounts cannot (as certified in an Officer’s Certificate to the Trustee) be avoided by the use of reasonable measures available to the Company, then the Company may, at its option, redeem the Securities then outstanding, in whole but not in
part, upon not less than 10 nor more than 60 days’ notice (such notice to be provided not more than 90 days before the next date on which the Payor would be obligated to pay Additional Amounts), at a redemption price equal to 100% of the

will become obligated to pay Additional Amounts because of any change or amendment described in this paragraph.

Indenture. 
 SECTION 3.02 Selection of Securities to Be Redeemed. If less than all of the Securities are to be redeemed at any time,
Securities will be selected for redemption on a pro rata basis (or, in the case of Securities issued in global form, based on a method as DTC may require) unless otherwise required by law or applicable stock exchange or Depositary
requirements. No Securities of US$1.00 or less may be redeemed in part. 
 SECTION 3.03 Notice of Redemption. Notices of redemption
shall be given by the Company in the manner provided for in Section 12.02 hereof not less than 30 but not more than 60 days before the redemption date to each holder of Securities to be redeemed, except (i) in the case of the redemption

 At the Company’s request, upon written notice provided at least five Business Days
prior to the giving of notice of redemption, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this

 SECTION 3.04 Effect of Notice of
Redemption. Once notice of redemption is delivered, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to the last sentence of this Section 3.04. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on
the related Interest Payment Date), and such Securities shall be canceled by the Trustee. 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. Any redemption or notice of
redemption may, at the Company’s option, be subject to the following conditions precedent: (i) completion of a Change of Control, (ii) completion of an Equity Offering and (iii) the incurrence of Indebtedness referred to in
clause (15) of the definition of “Permitted Debt.” 
 SECTION 3.05 Deposit of Redemption Price. Prior to 10 a.m. (New

if any, and accrued interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation. 

SECTION 3.06 Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part only, the notice of redemption that
relates to that Security shall state the portion of the principal amount of that Security that is to be redeemed and a new Security in principal amount equal to the unredeemed portion of the original Security shall be issued in the name of the
holder of Securities upon cancellation of the original Security. Securities called for redemption become due on the date fixed for redemption, and no interest shall accrue on any Securities so redeemed on or after the redemption date.

interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal, premium, if any, and interest then due. 

SECTION 4.02 Reports. So long as any Securities remain outstanding: 

(a) the Company shall provide the Trustee and holders of Securities with annual consolidated financial statements audited by the
Company’s independent public accountants 

  
 42 

 within 120 days after the end of the Company’s fiscal year, and unaudited quarterly consolidated
financial statements (including a balance sheet, income statement and cash flow statement for the fiscal quarter or quarters then ended and the corresponding fiscal quarter or quarters from the prior year) within 90 days of the end of each of the
first three fiscal quarters of each fiscal year. Such annual and quarterly financial statements will be prepared in accordance with IFRS and be accompanied by a management’s discussion and analysis of the results of operations and liquidity and
capital resources (which, for the avoidance of doubt, shall include descriptions of the Company’s current dividend policy and hedging policy) of the Company and its consolidated Subsidiaries for the periods presented in a level of detail
consistent with the management’s discussion and analysis of the results of operations and liquidity and capital resources of the Company and its consolidated Subsidiaries that the Company would be required to file pursuant to the Applicable
Securities Laws if the Company were subject to public company reporting in Canada. The Company shall also provide the holders of the Securities with annual guidance (which shall include disclosure regarding production levels and commodity mix,
expected costs, realized pricing, a capital expenditures budget, expected pace of drilling and the general geographic location of drilling plans) within 120 days after the end of the Company’s fiscal year. The Company shall also provide the
holders of the Securities with a Summary Engineering Report in respect of the Company’s reserves within 90 days after the end of each fiscal year. Such financial statements and related discussion and Summary Engineering Reports shall be made
available to holders of Securities and prospective investors in the Securities by posting on a password-protected or otherwise secured website maintained by the Company which may require a confidentiality acknowledgment. The Trustee will have no
responsibility to determine whether the posting of such financial statements and reports has occurred; delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall
not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled
to rely on Officer’s Certificates); 
 (b) the Company will schedule a conference call to be held at least three but not more than 15
Business Days following the release of each report containing the financial information only (which for the avoidance of doubt shall not include any Summary Engineering Report) referred to in Section 4.02(a) hereof, at which the Company will
make available appropriate members of its senior management (determined in the good faith judgment of the Company) to discuss the information contained in such report on such conference call. The Company will notify holders of Securities about such
call and provide them and prospective investors in the Securities with call-in information concurrently with and in the same manner as each delivery of financial statements pursuant to Section 4.02(a) hereof; 

(c) the Company shall disclose to the Trustee and holders of Securities the occurrence of any event directly concerning the Company or its
Subsidiaries that the Company determines in its good faith judgment would require disclosure if the Company were subject to Applicable Securities Laws, in each case within 10 days following the occurrence thereof (it being understood that any such
disclosure shall not mean ipso facto that such event is material to holders); provided that the Company may refrain from disclosing certain information to the Trustee and holders of Securities if the Company is permitted to not disclose that
information pursuant to the Oil and Gas Conservation Regulations issued under the Oil and Gas Conservation Act (Alberta), until such time as the Energy Resources Conservation Board (or equivalent regulatory authority) would have

  
 43 

 
required such information to be made available to the public. Disclosure of any such events shall be made by posting on the website referred to in Section 4.02(a) hereof accompanied by a
notice of such posting released on Bloomberg or a similar news service reasonably accessible to investors in securities such as the Securities; and 

(d) the Company will make available, upon request, to any holder and any prospective purchaser of Securities the information required pursuant
to Rule 144A(d)(4) under the Securities Act so long as the Securities are not freely transferable under the Securities Act by Persons who are not “affiliates.” 

None of the information provided pursuant to the preceding paragraphs shall be required to comply with Regulation S-K as promulgated by the SEC. In the event
that the Company becomes a “reporting issuer” (or its equivalent) in Canada or elsewhere prior to the maturity of the Securities, the disclosure requirements contemplated in Section 4.02(a) and Section 4.02(c) hereof will be
deemed to have been satisfied once the corresponding documents have been filed on the System for Electronic Document Analysis and Retrieval (or its equivalent in the United States) in the form and within the time periods required by Applicable
Securities Laws, as interpreted and applied by the Alberta Securities Commission, and the Company will no longer be required to hold conference calls or maintain a secured website as described in the foregoing paragraphs. 

While the Company is in registration (or the Canadian equivalent thereof) with respect to a Qualified IPO, the Company will not be required to disclose any
information or take any actions that, in the view of the Company upon the advice of counsel, would violate Applicable Securities Laws or the SEC’s “gun jumping” rules. 

SECTION 4.03 Taxes. The Company will pay, and the Company will cause each of its Subsidiaries to pay, prior to delinquency, all
material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Securityholders. 

SECTION 4.04 Restricted Payments. 

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly: 

 

	 	(1)	 declare or pay any dividend or make any other payment or distribution on account of the Company’s or any
Restricted Subsidiary’s Equity Interests (including, without limitation, any payment in connection with any consolidation, amalgamation, plan of arrangement or merger involving the Company or any Restricted Subsidiary) or to the direct or
indirect holders of the Company’s or any Restricted Subsidiary’s Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of such Person and other than

plan of arrangement or merger involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Restricted
Subsidiary; 

  

	 	(3)	 make any payment (whether on account of principal, interest, fees, premiums or other obligations) on or with

Company and any Restricted Subsidiary, (b) on or with respect to Capital Lease Obligations permitted under Section 4.05 and (c) any payment on or with respect to, repurchase, redemption, defeasance, discharge or other acquisition for
value of the Securities, and any amounts under any Credit Facility; or 

  

	 	(4)	 make any Restricted Investment; 

(all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted
Payments”), unless, at the time of and after giving effect to such Restricted Payment: 
  

	 	(a)	 no Default or Event of Default has occurred and is continuing or would occur as a consequence of such

Company and all Restricted Subsidiaries since the date of this Indenture (including all Restricted Payments permitted by Section 4.04(b) hereof but excluding Restricted Payments permitted by clauses (4), (5), (7), (9) and (10) of Sections
4.04(b) hereof), is less than or equal to the sum, without duplication, of:

end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit);
plus 

  

	 	(ii)	 [reserved]; 

  

	 	(iii)	 to the extent not already included in Consolidated Net Income for such period, if any Restricted Investment

such Restricted Investment resulting from such sale, liquidation or repayment (less any out-of-pocket costs incurred in connection with any such sale); plus

on the Company’s consolidated balance sheet upon the conversion or exchange (other than by the Company or any Restricted Subsidiary) subsequent to the date of this Indenture (excluding any reduction in the principal amount of the Securities
resulting from the amendment and restatement of the Existing Securities on the Amendment Date, or any redemption pursuant to paragraph 5(a) of the Securities) of any such Indebtedness or Disqualified Stock of the Company or the Restricted
Subsidiaries convertible into or exchangeable for Equity Interests (other than Disqualified Stock) of the Company (less the amount of any cash, or the Fair Market Value of any other property (other than such Equity Interests), distributed by the
Company upon such conversion or exchange and excluding the net cash proceeds from the conversion or exchange financed, directly or indirectly, using funds borrowed from the Company or any Subsidiary), together with the net proceeds, if any, received
by the Company or any Restricted Subsidiaries upon such conversion or exchange; plus 

  

	 	(v)	 to the extent that any Unrestricted Subsidiary designated as such created or acquired after the date of this

	 	(1)	 the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of
declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of this Indenture;

	 	(6)	 [reserved];

be, that was not permitted at the time of such sale or transfer by this Section 4.05 (b)(6); 
  

	 	(7)	 the issuance by any Restricted Subsidiary to the Company or to any Restricted Subsidiary of any Preferred

	 	(12)	 to the extent constituting Indebtedness, the incurrence by the Company or any Restricted Subsidiary of in-kind
obligations relating to net oil or natural gas balancing positions arising in the ordinary course of business; 

  

	 	(13)	 to the extent constituting Indebtedness, any obligation arising from agreements of the Company or any
Restricted Subsidiary providing for indemnification, adjustment of purchase price, earn outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Capital Stock of a
Restricted Subsidiary in a transaction permitted by this Indenture; 

  

	 	(14)	 Indebtedness representing deferred compensation to employees of the Company and the Restricted Subsidiaries;

  

	 	(15)	 the incurrence by the Company or any Restricted Subsidiary of Indebtedness, the issuance by the Company of
Disqualified Stock or the issuance by any Restricted Subsidiary of Preferred Stock to the extent that the net proceeds thereof are promptly deposited to defease or to satisfy and discharge the Securities, in each case, in accordance with and
pursuant to the applicable provisions of the this Indenture; and 

  

	 	(16)	 the incurrence of Indebtedness or the issuance of Disqualified Stock or Preferred Stock by (x) the Company
or any Restricted Subsidiary if incurred or issued to finance an acquisition or (y) by Persons that are acquired by the Company or any Restricted Subsidiary or merged, consolidated or amalgamated with or into the Company or any Restricted
Subsidiary in accordance with the terms of this Indenture; provided that after giving effect to such acquisition or merger, consolidation or amalgamation, 

 

	 	(a)	 with respect to the incurrence of Indebtedness the Ratio Test would not exceed 3.0 to 1.0; and

  
 51 

	 	(b)	 with respect to the issuance of Disqualified Stock and Preferred Stock, either (x) the Fixed Charge
Coverage Ratio would be at least 2.25 to 1.0 or (y) the Fixed Charge Coverage Ratio would be equal to or greater than the Fixed Charge Coverage Ratio immediately prior to such acquisition, or merger, consolidation or amalgamation.

 (c) The Company will not, and will not permit any Guarantor to incur any Indebtedness (including Permitted Debt) that
is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Securities or the applicable Note Guarantee on
substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company or any Guarantor solely by virtue of being unsecured or by
virtue of being secured on a junior priority basis. 
 (d) For purposes of determining compliance with this Section 4.05, in the event
that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) of Section 4.05(b), or is entitled
to be incurred pursuant to Section 4.05(a) hereof, the Company, in its sole discretion, will be permitted to divide, classify and reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) on the date
of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof), in any manner that complies with Section 4.05 hereof; provided that in the
event that the Company shall classify Indebtedness incurred on the date of determination as incurred in part pursuant to Section 4.05(a) hereof and in part pursuant to one or more clauses of the definition of “Permitted Debt”
(other than in respect of clause (16) of such definition), any calculation of Total Gross Debt in connection with the incurrence of Indebtedness pursuant to Section 4.05(a) hereof (but not in respect of any future calculation following
such date) shall not include any such Indebtedness (and shall not give effect to any repayment, repurchase, redemption, defeasance or other acquisition, retirement or discharge of Indebtedness from the proceeds thereof) to the extent incurred
pursuant to any such other clause of such definition. Indebtedness under Credit Facilities outstanding on the date on which Securities are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such
date in reliance on the exception provided by clause (1) of the definition of “Permitted Debt” and the Company shall not be permitted to reclassify all or any portion of such Indebtedness. The accrual of interest or Preferred
Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness not secured by a Lien in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as
Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional securities of the same class of Preferred Stock or Disqualified Stock will be deemed not to be an
incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.05; provided that the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the
definition of such term. 
 The amount of any Indebtedness outstanding as of any date will be: 

 

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

  
 52 

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

 

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

  

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

 

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

For purposes of determining compliance with any Canadian dollar-denominated restriction on the incurrence of any Indebtedness or incurrence of
Disqualified Stock or Preferred Stock, the Canadian dollar-equivalent principal amount of Indebtedness, Disqualified Stock or Preferred Stock denominated in a foreign currency, including U.S. dollars, shall be
calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred; provided that if such Indebtedness is incurred or Disqualified Stock or Preferred Stock is issued to refinance other Indebtedness,
Disqualified Stock or Preferred Stock denominated in a foreign currency, and such refinancing would cause the applicable Canadian dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the
date of such refinancing, such Canadian dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness, Disqualified Stock or Preferred Stock in the foreign currency so
denominated does not exceed the principal amount of such Indebtedness, Disqualified Stock or Preferred Stock in the foreign currency so denominated being refinanced. Notwithstanding any other provision of this Section 4.05, the maximum amount
of Indebtedness that may be incurred or Disqualified Stock or Preferred Stock issued pursuant to this Section 4.05 will be deemed not to have been exceeded with respect to any outstanding Indebtedness, Disqualified Stock or Preferred Stock due
solely to the result of fluctuations in the exchange rates of currencies. 
 SECTION 4.06 Restrictions on Distributions and Other
Payments by Restricted Subsidiaries. 
 (a) The Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
  

	 	(1)	 pay dividends or make any other distributions on its Capital Stock to the Company or any Restricted Subsidiary,
or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any Restricted Subsidiary; provided that the priority that any series of Preferred Stock of a Restricted
Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or
distributions on Capital Stock for purposes of this Section 4.06; 

  

	 	(2)	 make loans or advances to the Company or any Restricted Subsidiary; or 

  
 53 

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

 (b) Section 4.06(a) hereof shall not apply to encumbrances or restrictions existing under or by reason of: 

 

	 	(1)	 agreements governing Existing Indebtedness or Credit Facilities as in effect on the date of this Indenture and
any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or
refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture; 

 

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

 

	 	(3)	 agreements governing other Indebtedness permitted to be incurred under Section 4.05 hereof and any
amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the restrictions therein are not materially more restrictive, taken as a whole, than those contained
in this Indenture, the Securities and the Note Guarantees as in effect on the date of this Indenture; 

  

	 	(4)	 applicable law, rule, regulation, order, approval, governmental license, permit or similar restriction;

  

	 	(5)	 any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any Restricted
Subsidiary as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be
incurred; 

  

	 	(6)	 customary non-assignment provisions in purchase and sale or exchange agreements or in other contracts,
licenses, easements or leases, in each case, entered into in the ordinary course of business; 

  

	 	(7)	 purchase money obligations for property acquired in the ordinary course of business and Capital Lease
Obligations that impose restrictions on the property purchased or leased of the nature described in Section 4.06(a)(3) hereof; 

  
 54 

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

  

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

 

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

  

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

 

	 	(12)	 encumbrances or restrictions on cash or other deposits or net worth imposed by customers under contracts
entered into in the ordinary course of business; and 

  

	 	(13)	 an agreement or other instrument of an Unrestricted Subsidiary that is designated a Restricted Subsidiary and
that was in existence at the time of such designation; provided that such agreement or instrument was not created in contemplation of or in connection with such designation 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 designated. 

SECTION 4.07 Asset Sales. 

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

 

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

 

	 	(2)	 at least 75% of the aggregate consideration received in the Asset Sale by the Company or a Restricted
Subsidiary is in the form of cash or Cash 

  
 55 

	 	
Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 

  

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

  

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

 

	 	(C)	 any Capital Stock or assets of the kind referred to in Section 4.07(b)(3) or Section 4.07(b)(5)
hereof; 

  

	 	(D)	 with respect to any Asset Sale of any Oil and Gas Properties in the ordinary course of business where the
Company or a Restricted Subsidiary retains an interest in such property, the costs and expenses related to the exploration, development, completion or production of such Oil and Gas Properties and activities related thereto agreed to be assumed by
the transferee (or an Affiliate thereof) pursuant to a customary agreement; and 

  

	 	(E)	 any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such
Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (E) that is at that time outstanding, not to exceed C$5.0 million, with the Fair Market
Value of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value. 

(b) Within 180 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or any Restricted Subsidiary) may apply such Net
Proceeds: 
  

	 	(1)	 to repay and permanently reduce the commitments in respect of Indebtedness and other Obligations under any
Credit Facility that is secured by a Lien; 

  

	 	(2)	 to offer to equally and ratably reduce obligations under the Securities by making an offer (in accordance with
the procedures set forth in Section 4.07(c) hereof for an Asset Sale Offer) to all holders of Securities 

  
 56 

	 	
to purchase a pro rata principal amount of Securities at a price equal to 100% of the principal amount of Securities tendered to such offer, plus accrued and unpaid interest, if any, to,
but not including, the date of purchase; 

  

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

  

	 	(4)	 any combination of the foregoing. 

Pending the final application of any Net Proceeds, the Company or any Restricted Subsidiary may reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture. 
 (c) Any Net Proceeds from Asset Sales that are not applied or invested
as provided in Section 4.07(b) hereof shall constitute “Excess Proceeds”; provided that any amount of proceeds offered to holders pursuant to Section 4.07(b)(2)(b) hereof or pursuant to an Asset Sale Offer made at
any time after the Asset Sale shall be deemed to have been applied as required and shall not be deemed to be Excess Proceeds without regard to the extent to which such offer is accepted by the holders. When the aggregate amount of Excess Proceeds
exceeds C$10.0 million, within ten Business Days thereof, the Company will make an offer (an “Asset Sale Offer”) to all holders of Securities and, if required by the terms of any Indebtedness that is pari passu with the
Securities, to all holders of such other Indebtedness, to purchase, prepay or redeem, on a pro rata basis, the maximum principal amount of Securities and such other pari passu Indebtedness (plus all accrued and unpaid interest on the
Securities and such other Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The Company may elect to commence such Asset
Sale Offer prior to the completion of the 180-day period specified above and/or prior to the aggregate amount of Excess Proceeds exceeding C$10.0 million. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of
the Securities and such other Indebtedness, plus accrued and unpaid interest, if any, to, but not including, the date of purchase, prepayment or redemption, subject to the rights of holders of Securities and such other Indebtedness on the relevant
record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds
for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities and such other Indebtedness (plus all accrued and unpaid interest on the Securities and such other Indebtedness and the amount of all fees
and expenses, including premiums, incurred in connection therewith) tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds allocated to the purchase of Securities and such other Indebtedness, the Trustee will select the Securities
and such other Indebtedness to be purchased on a pro rata basis (except that any Securities represented by a Security in global form will be selected by such method as DTC may require), based on the amounts tendered (with such adjustments as
may be deemed appropriate by the Company so that only Securities in denominations of US$1.00, or an integral multiple of US$1.00 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be
reset at zero. 

  
 57 

 (d) Notwithstanding clauses (a) through (c) of this Section 4.07, the sale,
conveyance or other disposition of all or substantially all of the properties and assets of the Company and the Restricted Subsidiaries, taken as a whole, will be governed by Section 4.09 and/or Article 5 hereof and not by this
Section 4.07. 
 (e) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws
and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Securities pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict
with this Section 4.07 or compliance with this Section 4.07 would constitute a violation of any such laws or regulations, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached
its obligations under this Section 4.07 by virtue of such compliance. 
 SECTION 4.08 Transactions with Affiliates. 

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

	 	(1)	 the Affiliate Transaction is on terms that are not less favorable (taken as a whole) to the Company or the
relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company; and 

 

	 	(2)	 the Company delivers to the Trustee: 

 

	 	(A)	 with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of C$3.0 million, an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.08; and 

 

	 	(B)	 with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of C$7.5 million, a resolution of the Board of Directors of the Company set forth in an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this
Section 4.08 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any. 

  
 58 

 (b) The following items will be deemed not to be Affiliate Transactions and, therefore, will
not be subject to Section 4.08(a) hereof: 
  

	 	(1)	 any employment or consulting agreement, employee benefit plan, stock ownership or stock option plan, officer or
director indemnification, compensation or severance agreement or any similar arrangement entered into by the Company or any Restricted Subsidiary in the ordinary course of business and payments, awards, grants or issuances pursuant thereto;

  

	 	(2)	 loans or advances to employees of the Company or any Restricted Subsidiary on or after the Amendment Date made
in the ordinary course of business in an aggregate principal amount not to exceed C$1.0 million; 

  

	 	(3)	 transactions between or among the Company and/or any Guarantors; 

 

	 	(4)	 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 Restricted Subsidiary, an Equity Interest in, or controls, such Person; 

  

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

  

	 	(6)	 any sale or issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the
Company; 

  

	 	(7)	 Permitted Investments (other than pursuant to clauses (3), (9), (11), (13) and (14) of the definition
thereof) or Restricted Payments that do not violate Section 4.04 hereof; 

  

	 	(8)	 transactions effected, and payments made, in accordance with the terms of the agreements as such agreements are
in effect on the date of this Indenture, and any amendment or replacement of any of such agreements so long as such amendment or replacement agreement is no less advantageous to the Company or the applicable Restricted Subsidiary in any material
respect than the agreement so amended or replaced; and 

  

	 	(9)	 any agreement as in effect as of the date hereof or any amendment thereto or replacement or similar transaction
(so long as any such agreement together with all amendments thereto or replacements or similar transactions, taken as a whole, are not more disadvantageous to the Company and its Restricted Subsidiaries than the original agreement as in effect on
the date hereof) or any transaction contemplated thereby. 

 Notwithstanding the foregoing, without prejudice to the
provisions of Section 4.20 hereof, the Company or any Restricted Subsidiary shall not form, invest in or otherwise enter into any 

  
 59 

 
Financial Drilling Joint Venture or enter into or permit to exist any farm-out agreements or arrangements with any Affiliates of the Company unless (x) such transaction is on terms that are
not less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company,
(y) the Company shall deliver to the Trustee a resolution of the Board of Directors of the Company set forth in an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with
this covenant and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company, and (z) with respect to any such Financial
Drilling Joint Ventures or farm-out agreements or arrangements that involve total assets with a fair market value in excess of C$10.0 million, the Company shall deliver to the Trustee an opinion as to the fairness to the Company or such
Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing; provided that the Company shall
not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any farm-out agreements or arrangements with any Affiliates of the Company that involve total assets with a fair market value, together with the fair market value
of the total assets of all other farm-out agreements or arrangements with Affiliates of the Company pursuant to this paragraph, in excess of C$25.0 million in the aggregate at any time outstanding. 

SECTION 4.09 Change of Control. 

(a) If a Change of Control occurs, unless the Company has exercised its right to redeem all of the Securities as described in Article 3 hereof,
each holder of Securities will have the right to require the Company to repurchase all or any part (equal to US$1.00 or an integral multiple of US$1.00 in excess thereof) of that holder’s Securities pursuant to an offer (a “Change of
Control Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer a payment (a “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of
Securities repurchased, plus accrued and unpaid interest, if any, on the Securities repurchased, to, but not including, the date of purchase (the “Change of Control Purchase Date”), subject to the rights of holders of Securities on
the relevant record date to receive interest due on the relevant Interest Payment Date. 
 (b) Prior to or within 30 days following any
Change of Control, the Company shall send a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Securities validly tendered prior to the expiration date specified in the
notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required by this Indenture and described in such notice. The Company shall comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed not to have breached its
obligations under the Change of Control provisions of this Indenture by virtue of such conflict. 

  
 60 

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

 

	 	(1)	 deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Securities or
portions of Securities validly tendered; and 

  

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

(d) The Paying Agent shall promptly mail or wire transfer to each holder of Securities validly tendered the Change of Control Payment for such
Securities (or, if all the Securities are then in global form, make such payment through the facilities of DTC), and the Trustee shall, upon direction by the Company, 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; provided that each new Security will be in a principal amount of US$1.00 or an integral multiple of US$1.00 in excess thereof.
The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date. 

(e) On the Change of Control Purchase Date, all Securities purchased by the Company under this Section 4.09 shall be delivered by the
Company to the Trustee for cancellation, and the Company shall pay the Change of Control Payment to the holders entitled thereto. 
 (f) The
Company shall not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not validly withdrawn under the Change of Control Offer, (2) a notice of redemption has been given pursuant to this
Indenture and pursuant to paragraph 5 of the Securities unless and until there is a default in payment of the applicable redemption price or (3) in connection with or in contemplation of any Change of Control, it or a third party has made an
offer to purchase (an “Alternate Offer”) any and all Securities validly tendered at a cash price equal to or higher than the Change of Control Payment in the manner, at the time and otherwise in compliance with the requirements set
forth in this Indenture applicable to a Change of Control Offer made by the Company and has purchased all Securities validly tendered in accordance with the terms of such Alternate Offer. Notwithstanding anything to the contrary contained herein, a
Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 

(g) Securities repurchased by the Company pursuant to a Change of Control Offer will have the status of Securities issued but not outstanding
or will be retired and cancelled, at the option of the Company. Securities purchased by a third party pursuant to Section 4.09(f)(1) hereof will have the status of Securities issued and outstanding. 

  
 61 

 (h) In the event that holders of not less than 90% in aggregate principal amount of the
outstanding Securities accept a Change of Control Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company pursuant to Section 4.09(f)(1) hereof) purchases all of the Securities held by such holders,
the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Securities that remain outstanding
following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Securities, that remain outstanding, to, but not
including, the date of redemption (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 redemption date). 

SECTION 4.10 Liens. The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or otherwise cause or
suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness (including Attributable Debt) upon any of their property or assets, now owned or hereafter acquired. 

SECTION 4.11 Limitation on Sale and Leaseback Transactions. The Company will not, and will not permit any Restricted Subsidiary to,
enter into any sale and leaseback transaction; provided that the Company or any Guarantor may enter into a sale and leaseback transaction if: 

(a) (i) the Ratio Test for the Company’s most recently ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date on which such Attributable Debt is incurred would not exceed 3.0 to 1.0, determined on a pro forma basis after giving effect to the incurrence of the Attributable Debt relating to such sale and
leaseback as if the Attributable Debt relating to such sale and leaseback had been incurred at the beginning of such four-quarter period, and (ii) the Company or that Guarantor, as applicable, could have incurred a Lien to secure such
Indebtedness pursuant to Section 4.10 hereof; 
 (b) the gross cash proceeds of that sale and leaseback transaction are at least equal
to the Fair Market Value of the property that is the subject of that sale and leaseback transaction; and 
 (c) the transfer of assets in
that sale and leaseback transaction is permitted by, and the application of the proceeds of such transaction by the lessee does not violate, Section 4.07 hereof. 

SECTION 4.12 Guarantees. If the Company or any Restricted Subsidiary acquires or creates a Restricted Subsidiary after the date hereof
that becomes a borrower, or guarantees the obligations of the Company, under the Credit Agreement or that incurs or guarantees any other Indebtedness, which other Indebtedness exceeds C$5.0 million principal amount, then that Subsidiary will
become a Guarantor by executing a supplemental indenture in the form attached hereto as Exhibit B, which is hereby incorporated in, and expressly made part of, this Indenture, and delivering an Opinion of Counsel satisfactory to the Trustee
within 20 Business Days after the date that such Subsidiary guaranteed or incurred such other Indebtedness. 

  
 62 

 SECTION 4.13 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 to the Company and the Restricted Subsidiaries taken as a whole. 

SECTION 4.14 Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would
not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company or the Restricted Subsidiaries in the Subsidiary designated as an
Unrestricted Subsidiary will be deemed to be either an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under Section 4.04 hereof or represent a Permitted Investment under one or
more clauses of the definition of “Permitted Investments,” as determined by the Company. Such designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an “Unrestricted Subsidiary.” 
 (b) Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the
preceding conditions and was permitted by Section 4.04 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary
for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the covenant described
under Section 4.05 hereof, the Company will be in default of such covenant. 
 (c) The Board of Directors of the Company may at any
time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted
Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.05 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable
reference period; and (2) no Default or Event of Default would be in existence following such designation. 
 SECTION 4.15
Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officer’s Certificate signed by one of the principal executive officer, the principal financial officer
or the principal accounting officer of the Company (in addition to another signatory) regarding compliance with this Indenture to the best of the knowledge of the signatories thereto. Within 30 days of any officer of the Company becoming aware of
any Default or Event of Default, the Company shall deliver to the Trustee a written statement specifying such Default or Event of Default. 

  
 63 

 SECTION 4.16 Suspension of Certain Covenants when Securities Are Rated Investment
Grade. 
 (a) If on any date following the date of this Indenture: 

 

	 	(1)	 the Securities are rated by both of the Rating Agencies as having an Investment Grade Rating; and

  

	 	(2)	 no Default or Event of Default shall have occurred and be continuing, 

then, upon the Company’s delivery of notice of such events to the Trustee, the covenants described in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.11(a)(i),
4.11(c), 4.14 and 5.01(a)(4) hereof are suspended. 
 (b) During any period that the covenants described in Sections 4.04, 4.05, 4.06, 4.07,
4.08, 4.11(a)(i), 4.11(c), 4.14 and 5.01(a)(4) hereof have been suspended, the Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the covenant described in Section 4.14 hereof.

 (c) Notwithstanding the foregoing, if the rating assigned by either such Rating Agency should subsequently decline to below Investment
Grade Rating, the covenants described in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.11(a)(i), 4.11(c), 4.14 and 5.01(a)(4) hereof will be reinstituted as of and from the date of such rating decline (the “Reversion Date”). In the event
of any such reinstatement, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the suspended covenants during a suspension period (or on the Reversion Date or after the suspension period based
solely on events that occurred during the suspension period). On each Reversion Date, all Indebtedness incurred, and Disqualified Stock and Preferred Stock issued, during the suspension period prior to such Reversion Date will be deemed to be
Permitted Indebtedness that falls within the scope of the definition of Existing Indebtedness and is permitted under Section 4.05(b)(2) hereof. Calculations under the reinstated covenant described in Section 4.04 hereof will be made as if
the Restricted Payments had been in effect since the date of this Indenture, except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while the covenant described in Section 4.04 hereof was suspended.
In addition, for the purposes of Sections 4.06 and 4.08 hereof, all agreements and arrangements entered into during the period in which such covenants are suspended shall be deemed to have been entered into and existing prior to the date of this
Indenture and any Indebtedness incurred during such period shall be deemed to be Permitted Debt under Section 4.05(b)(2) hereof. The Company will notify the Trustee if the Reversion Date has occurred, promptly after becoming aware of same. 

SECTION 4.17 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

  
 64 

 SECTION 4.18 Payments for Consent. The Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration in any form and whether paid pursuant to one transaction or a series of transactions to or for the benefit of any holder of Securities for or as an inducement to
any consent, waiver, supplement or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid to all holders (with ten Business Days to consider such offer) and is paid to all
holders of the Securities that consent, waive or agree to supplement or amend in the time frame set forth in the solicitation documents relating to such consent, waiver, supplement or agreement. 

SECTION 4.19 Production Payments. The Company will not, and will not permit any Restricted Subsidiary to, engage in any Production
Payments. 
 SECTION 4.20 Financial Drilling Joint Ventures. The Company will not, and will not permit any Restricted Subsidiary to,
make any Investment in Financial Drilling Joint Ventures that involve total assets with a fair market value, together with the fair market value of the total assets of all other Financial Drilling Joint Ventures invested pursuant to this
Section 4.20, in excess of C$50.0 million in the aggregate at any time outstanding. 
 SECTION 4.21 Required Oil and Gas
Hedging Contracts. The Company shall maintain one or more Oil and Gas Hedging Contracts, the notional volumes for which are at least 50% of the Expected Production, as reasonably anticipated as of the Issue Date as set forth in the Summary
Engineering Report, for each month during the period during which any such Oil and Gas Hedging Contracts is in effect for crude oil and/or natural gas, each calculated separately for the period commencing on the Issue Date (or earlier, if
applicable) until the 24-month anniversary of the Issue Date (if applicable), and at all times thereafter shall maintain hedges for the same percentage of notional volumes on a rolling 24-month basis; provided that the Company shall have 90 days following the earlier of the receipt of the Summary Engineering Report and when the Summary Engineering Report is due pursuant to Section 4.02
hereof to ensure that it is compliance with the hedging requirement set forth herein. 
 ARTICLE 5

(whether or not the Company is the survivor), or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless: 

 

	 	(1)	 either: (A) the Company is the surviving or, in the case of amalgamation, continuing Person; or
(B) the Person formed by or surviving any such consolidation, amalgamation, combination or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or

of Columbia; 

  

	 	(2)	 the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to

agreements reasonably satisfactory to the Trustee; 

  

	 	(3)	 immediately after such transaction, no Default or Event of Default exists; 

 

	 	(4)	 immediately after giving effect to such transaction and any related financing transaction on a pro forma
basis as if the same had occurred at the beginning of the applicable four-quarter period, either the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment,
transfer, conveyance, lease or other disposition has been made, would be permitted to incur at least C$1.00 of additional Indebtedness pursuant to the proviso set forth in Section 4.05(a) hereof or the Ratio Test of the Company or the Person
formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance, lease or other disposition has been made, is not greater than the Ratio Test of the Company immediately
prior to such transaction; and 

  

	 	(5)	 the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating

consolidation, amalgamation, combination or merger between or among any of the Company and the Restricted Subsidiaries. Sections 5.01(a)(3) and 5.01(a)(4) hereof shall not apply to any consolidation, amalgamation, combination or merger of the
Company with or into an Affiliate solely for the purpose of reorganizing the Company in another jurisdiction. 
 SECTION 5.02 The
Guarantors May Consolidate, Etc. Only on Certain Terms. Each Guarantor may not, directly or indirectly: (1) consolidate, amalgamate or combine with or merge with or into another Person (whether or not such Guarantor is the surviving
Person), or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless: 

 

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

  
 66 

	 	(2)	 either: 

  

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

  

	 	(B)	 such transaction or series of transactions does not violate Section 4.07 hereof. 

Notwithstanding the foregoing, this Section 5.02 shall not apply to any sale, assignment, transfer, conveyance, lease or other
disposition of assets or consolidation, amalgamation, combination or merger between or among the Company and any Guarantors. 
 ARTICLE 6

 DEFAULTS AND REMEDIES 

SECTION 6.01 Events of Default. Each of the following is an “Event of Default”: 

 

	 	(1)	 default for 30 days in the payment when due of interest, if any, on the Securities; 

 

	 	(2)	 default in the payment when due (at Stated Maturity, upon redemption or otherwise) of the principal of, or
premium, if any, on, the Securities; 

  

	 	(3)	 failure by the Company to comply with Section 4.07, Section 4.09, Section 4.18 and Article 5
hereof; 

  

	 	(4)	 failure by the Company or any Restricted Subsidiary for 60 days after notice to the Company by the Trustee or
the holders of at least 25% in aggregate principal amount of the Securities then outstanding to comply with any of the other agreements in this Indenture; 

  

	 	(5)	 default under any mortgage, indenture or instrument under which there may be issued or by which there may be
secured or evidenced any Indebtedness for money borrowed by the Company or any Restricted Subsidiary (or the payment of which is guaranteed by the Company or any Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is
created after the date of this Indenture, if that default: 

  

	 	(A)	 is caused by a failure to pay principal of, premium on, if any, or interest, if any, on, such Indebtedness when
due after giving effect to any grace period provided in such Indebtedness (a “Payment Default”); or 

  
 67 

	 	(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 C$5.0 million or more; provided
that if any such Payment Default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within 10 Business Days from the continuation of such Default beyond the applicable grace period or the occurrence of such
acceleration, as the case may be, such Event of Default and any acceleration of the Securities caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree
or applicable law; 

  

	 	(6)	 failure by the Company or any Restricted Subsidiary to pay final judgments entered by a court or courts of
competent jurisdiction aggregating in excess of C$5.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or
stayed, for a period of 60 days; 

  

	 	(7)	 except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be
unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; 

 

	 	(8)	 the Company, or any Restricted Subsidiary that is a Significant Subsidiary or group of Restricted Subsidiaries
that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

  

	 	(A)	 commences a voluntary case under any Bankruptcy Law; 

 

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

 

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

or takes any comparable action under any foreign laws relating to insolvency, bankruptcy, reorganization, arrangement or compromise, including
any provisions of corporate statutes of like effect; and 
  

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

  

	 	(A)	 is for relief against the Company, any Guarantor, any Significant Subsidiary or group of Restricted
Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary in an involuntary case; 

  
 68 

	 	(B)	 appoints a Securities Custodian of the Company, any Guarantor, any Significant Subsidiary or group of
Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, or for any substantial part of its or their
property; or 

  

	 	(C)	 orders the winding-up or liquidation of the Company, any Guarantor, any
Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary;

 or any similar relief is granted under any foreign laws (including pursuant to any corporate statutes providing for a
stay of proceedings or similar relief) and the order or decree remains unstayed and in effect for 60 days. 
 The foregoing shall constitute
Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body. 
 However, a default under clause (4) of this Section 6.01 will not constitute an Event of
Default until the Trustee or the holders of 25% in principal amount of the outstanding Securities notify the Company of the default and the Company or any Restricted Subsidiaries do not cure such default within the time specified after receipt of
such notice. Such notice must be in writing, specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” 

SECTION 6.02 Acceleration. In the case of an Event of Default specified in Section 6.01(8) or 6.01(9) hereof, with respect to the
Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Securities will become due and payable immediately without
further action or notice. 
 In case of an Event of Default arising from non-compliance with
Section 4.18 hereof, the Trustee or any affected holder may declare all the Securities to be due and payable immediately by notice in writing to the Company specifying the Event of Default. 

If any other Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the
then-outstanding Securities may declare all the Securities to be due and payable immediately by notice in writing to the Company specifying the Event of Default. 

The holders of a majority in principal amount of the then-outstanding Securities by written notice to the Trustee may rescind any such
acceleration with respect to the Securities and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived, except nonpayment of principal of, premium on, if any,
or interest, if any, on the Securities or arising from non-compliance with Section 4.18 hereof. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

  
 69 

 SECTION 6.03 Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 

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 Securityholder 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 6.04 Waiver of Past Defaults.
The holders of a majority in principal amount of the then-outstanding Securities by written notice to the Trustee may, on behalf of the holders of all of the Securities, rescind an acceleration or waive any existing Default or Event of Default and
its consequences under this Indenture, if the rescission would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Securities or
arising from non-compliance with respect to Section 4.18 hereof. 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
impair any consequent right. 
 SECTION 6.05 Control by Majority. The holders of a majority in principal amount of the
then-outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee shall refuse to follow any
direction that conflicts with any affected holder relating to any such proceeding relating to the enforcement of the right to receive payment of principal, premium, if any, or interest, when due, or to enforce Section 4.18 hereof, and may
refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01 hereof, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal
liability; provided, however, that the Trustee may withhold from holders of the Securities notice of any continuing Default or Event of Default if the Trustee determines that withholding notice is not opposed to the interest of the
holders of the Securities, except a Default or Event of Default relating to the payment of principal of, premium on, if any, and interest, on the Securities. 

SECTION 6.06 Limitation on Suits. Subject to Article 7 hereof, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any holders of Securities unless such holders have offered to the Trustee indemnity or security satisfactory to it against any loss,
liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest, when due, or to enforce Section 4.18 hereof, no holder of a Security may pursue any remedy with respect to this Indenture or the
Securities unless: 
  

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

  

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

  
 70 

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

  

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

  

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

 A
Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. In the event that the Definitive Securities are not issued to any beneficial owner
promptly after the Registrar has received a request from the holder of a Global Security to issue such Definitive Securities to such beneficial owner of its nominee, the Company expressly agrees and acknowledges, with respect to the right of any
holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial holder’s Securities as if such
Definitive Securities had been issued. 
 SECTION 6.07 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 6.08
Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as Trustee of an express trust against the Company for the
whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07. 

SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on
behalf of the holders in any election of a Trustee in bankruptcy or other Person performing similar functions, and any Securities Custodian in any such judicial proceeding is hereby authorized by each holder to make payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly to the holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its
counsel, and any other amounts due such Trustee under Section 7.07 hereof. 
 SECTION 6.10 Priorities. If the Trustee collects
any money or property pursuant to this Article 6, it shall pay out the money or property in the following order: 
 FIRST: to the Trustee
for amounts due under Section 7.07 hereof; 

  
 71 

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

THIRD: to the Company or to such party as a court of competent jurisdiction shall direct, including a Guarantor, if applicable. 

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days
before such record date, the Company shall send to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid. 

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

SECTION 6.12 Waiver of Stay or Extension Laws. Each of the Company and the Guarantors (to the extent it may lawfully do so) shall not
at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this
Indenture; and each of the Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE 7 

TRUSTEE 
 SECTION
7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee, once it becomes aware of any such
Event of Default, shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s
own affairs. 
 (b) Except during the continuance of an Event of Default: 

 

	 	(1)	 the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

  
 72 

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

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

	 	(1)	 this Section 7.01(c) does not limit the effect of Section 7.01(b) hereof; 

 

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

  

	 	(3)	 the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 6.04 and 6.05 hereof; and 

  

	 	(4)	 no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such
risk or liability is not reasonably assured to it. 

 (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01. 
 (e) The Trustee shall not be liable for interest on any

segregated from other funds except to the extent required by law. 
 (g) The permissive authorizations, entitlements, powers and rights
(including the right to request that the Company take an action or deliver a document and the exercise of remedies following an Event of Default) granted to the Trustee herein shall not be construed as duties. 

SECTION 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper Person.
The Trustee need not investigate any fact or matter stated in the document.

Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in conclusive reliance on the Officer’s Certificate or Opinion of Counsel. 

(c) The Trustee may act through agents or attorneys and shall not be responsible for the misconduct or negligence of any agent or attorney
appointed with due care. 
 (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to
be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or gross negligence. 

(e) The Trustee may consult with counsel of its selection, and the advice or Opinion of Counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. 

(f) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

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

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

(i) The Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order or
direction of any of the holders of Securities pursuant to the provisions of this Indenture, unless such holders of Securities shall have offered to the Trustee, security or indemnity satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred therein or thereby. 
 (j) The Trustee may at any time request, and the Company shall deliver an
Officer’s Certificate setting forth the specimen signatures and the names of individuals and/or titles of Officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by
any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(k) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or 

  
 74 

 
document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further
inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason
of such inquiry or investigation. 
 SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity
may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11 hereof. 

SECTION 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Securities; it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication. 
 SECTION 7.05
Notice of Defaults. If a Default occurs, is continuing and is actually known to the Trustee, the Trustee shall mail to each Securityholder notice of the Default within 90 days after it occurs unless such Default shall have been cured or
waived. Except in the case of a Default in the payment of principal of, premium, if any, or interest on any Security, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is not opposed to the
interests of the Securityholders. 
 SECTION 7.06 Reports by Trustee to Holders. As promptly as practicable, upon the Company’s
request, the Trustee shall deliver to each Securityholder any report received by the Trustee from the Company pursuant to Section 4.02 hereof. 

SECTION 7.07 Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as
agreed by the Company and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a Trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable expenses incurred or
made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and
experts. The Company and the Guarantors jointly and severally, shall indemnify the Trustee and its officers, directors, employees and agents against any and all loss, liability, damage, claim or expense (including attorneys’ fees and expenses)
including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any holder or any other
Person) incurred by it in connection with the administration of this Indenture and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not
reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee determined to have been caused by the Trustee’s own willful misconduct or gross negligence. 

  
 75 

 To secure the Company’s payment obligations in this Section 7.07, the Trustee
shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities. 

The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture and the resignation or
removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or 6.01(8) hereof with respect to the Company, the expenses are intended to constitute expenses of administration under the
Bankruptcy Law. 
 SECTION 7.08 Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The holders
of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and the Company not less than 30 days prior the effective date of such removal and may appoint a successor Trustee. The Company may remove the
Trustee if: 
  

	 	(1)	 the Trustee fails to comply with Section 7.10 hereof; 

 

	 	(2)	 the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee
under any Bankruptcy Law; 

  

	 	(3)	 a receiver or other public officer takes charge of the Trustee or its property; or 

 

	 	(4)	 the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed by the Company or by the holders of a majority in principal amount of the Securities and such holders do
not reasonably and promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon
the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07 hereof. 

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, at the
expense of the Company, or the holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

  
 76 

 If the Trustee fails to comply with Section 7.10 hereof, any Securityholder may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding
the replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 

SECTION 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by
this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and in case
at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases
such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee
(together with its parent) shall have a combined capital and surplus of at least US$50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however,
that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for
such exclusion set forth in TIA § 310(b)(1) are met. 
 SECTION 7.11 Preferential Collection of Claims Against the Company. The
Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated. 

ARTICLE 8 

DEFEASANCE 

SECTION 8.01 Discharge of Liability on Securities; Defeasance. 

(a) The Company may at any time, at its option, elect to have all of its obligations discharged with respect to the outstanding Securities and
all obligations of the Guarantors discharged with respect to their Note Guarantees (“Legal Defeasance”) except for: 
  

	 	(1)	 the rights of holders of outstanding Securities to receive payments in respect of the principal of, premium on,
if any, or interest, if any, on, such Securities when such payments are due from the trust pursuant to Section 8.01(a)(2) hereof; 

  
 77 

	 	(2)	 the Company’s obligations with respect to the Securities concerning issuing temporary Securities,
registration of Securities, mutilated, destroyed, lost or stolen Securities and the maintenance of an office or agency for payment and money for security payments held in trust; 

 

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

  

	 	(4)	 the provisions of this Article 8 with respect to Legal Defeasance. 

(b) The Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors released with respect
to Sections 4.02, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.19, 4.20, 4.21 and 5.01(a)(4) hereof (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute
a Default or Event of Default with respect to the Securities. In the event Covenant Defeasance occurs, all Events of Default described under Section 6.01 hereof (except Sections 6.01(1), (2), (8) and (9)) will no longer constitute an Event of
Default with respect to the Securities. 
 SECTION 8.02 Conditions to Defeasance. In order to exercise either Legal Defeasance or
Covenant Defeasance: 
  

	 	(1)	 the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the holders of the
Securities, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or
firm of independent public accountants, to pay the principal of, premium on, if any, and interest, if any, to, but not including, the stated date for payment of the Securities or the applicable redemption date (as applicable), on, the outstanding
Securities on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Securities are being defeased to such stated date for payment or to a particular redemption date;

  

	 	(2)	 in the case of Legal Defeasance, the Company must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Indenture, there has been a change in the applicable U.S.
federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the holders of the outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

  
 78 

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

  

	 	(4)	 no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default
or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings); 

 

	 	(5)	 such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a
default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries is bound; 

  

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

 

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

SECTION 8.03 Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it
pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent (including the Company or a Guarantor acting as Paying Agent) as the Trustee may determine, to the payment of
principal of and interest on the Securities in accordance with this Indenture. 
 SECTION 8.04 Repayment to the Company. The Trustee
and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time. 

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors. 

SECTION 8.05 Indemnity for Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations other than such tax, fee or other charge which by law is for the account of the holders of the
outstanding Securities. 

  
 79 

 SECTION 8.06 Reinstatement. If the Trustee or Paying Agent is unable to apply any
money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court of competent jurisdiction or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company’s and each Guarantor’s obligations under this Indenture with respect to the Securities and each Guarantee shall be revived and reinstated as though no deposit had occurred pursuant to this Article
8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on,
premium, if any, or principal of any Securities because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the holders of such Securities to receive such payment from the money or U.S. Government Obligations
held by the Trustee or Paying Agent. 
 ARTICLE 9 

AMENDMENTS 

SECTION 9.01 Without Consent of Holders. Without the consent of any holder of Securities, the Company, the Guarantors and the Trustee

 80 

	 	(9)	 comply with the rules of any applicable Depositary; 

 

	 	(10)	 add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case

 After an amendment under this Section 9.01 becomes effective, the Company shall mail to holders of the Securities
a notice briefly describing such amendment. The failure to give such notice to all holders of the Securities, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01. 

SECTION 9.02 With Consent of Holders. Except as otherwise provided in this Indenture, the Securities or the Note Guarantees, this
Indenture, the Securities or the Note Guarantees may be amended or supplemented with the consent of the holders of a majority in aggregate principal amount of the then-outstanding Securities (including, without limitation, additional Securities, if
any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Securities), and any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium on, if any, or interest, if any, on, the Securities, except a Payment Default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the
Securities or the Note Guarantees may be waived with the consent of the holders of a majority in aggregate principal amount of the then-outstanding Securities (including, without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Securities). However, without the consent of each holder of Securities affected, an amendment, supplement or waiver may not (with respect to any Securities held by a
non-consenting holder): 
  

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

  

	 	(2)	 reduce the principal of or change the fixed maturity of any Security or alter or waive any of the provisions
with respect to the redemption or repurchase of the Securities (except Sections 4.07 and 4.09 hereof); 

  

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

  

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

  
 81 

	 	(5)	 make any Security payable in money other than that stated in the Securities; 

 

	 	(6)	 make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of
holders of Securities to receive payments of principal of, premium on, if any, or interest, if any, on, the Securities (other than as permitted by Section 9.02(7) hereof); 

 

	 	(7)	 waive a redemption or repurchase payment with respect to any Security (other than a payment required by
Section 4.07 or 4.09 hereof); 

  

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

  

	 	(9)	 make any change, supplement or waiver to Section 4.18 hereof; or 

 

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

It shall not be necessary for the consent of the holders under this Section 9.02 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment under this Section 9.02
becomes effective, the Company shall send to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under
this Section 9.02. 
 SECTION 9.03 Reserved. 

SECTION 9.04 Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a holder of a Security shall bind
the holder and every subsequent holder of that Security or portion of the Security that evidences the same debt as the consenting holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such holder
or subsequent holder may revoke the consent or waiver as to such holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective in accordance with its terms. 
 The
Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture.
If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to
revoke any consent previously given or to take any such action, whether or not such Persons continue to be holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 

  
 82 

 SECTION 9.05 Notation on or Exchange of Securities. If an amendment changes the terms
of a Security, the Company may require the holder of the Security to deliver it to the Trustee. The Trustee shall, in that case, place an appropriate notation on the Security regarding the changed terms and return it to the holder. Alternatively, if
the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect
the validity of such amendment. 
 SECTION 9.06 Trustee to Sign Amendments. In executing, or accepting the additional trusts created
by, any amendment or supplemental indenture permitted by this Article 9 or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, an Opinion of Counsel and an Officer’s Certificate stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent to the execution
have been complied with. The Trustee may, but shall not be obligated to, enter into any amendment or supplemental indentures which affect the Trustee’s own rights, duties, immunities, or indemnities under this Indenture, the Securities or
otherwise. The Trustee will sign any amendment or supplemental indenture authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. 

ARTICLE 10 

GUARANTEES 

SECTION 10.01 Guarantees. 

(a) Each Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally on an unsecured basis, to each holder and to the
Trustee and its successors and assigns (1) the full and punctual payment of principal of, premium on, and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations
of the Company under this Indenture and the Securities and (2) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing being
hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and
that such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation. 
 (b)
To the fullest extent allowed by applicable law, each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and will also waive notice of protest for nonpayment. To the fullest
extent allowed by applicable law, each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor shall not be affected by: (1) 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 (including any Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof;
(3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the 

  
 83 

 
Securities or any other agreement; (4) the release of any security held by any holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any holder or the
Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06 hereof, any change in the ownership of such Guarantor. 

Each Guarantor further agrees that its Note Guarantee constitutes a guarantee of payment, performance and compliance when due (and not a
guarantee of collection) and (to the extent it may lawfully do so) will waive any right to require that any resort be had by any holder or the Trustee to any security held for payment of the Guaranteed Obligations. 

(c) To the fullest extent allowed by applicable law, except as expressly set forth in Sections 8.01(b), 10.02 and 10.06 hereof, the
obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense
of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, to the fullest extent allowed
by applicable law, the obligations of each Guarantor shall not be discharged or impaired or otherwise affected by the failure of any holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or
any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by 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 such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity. 

(d) Each Guarantor further agrees that its Note Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of, premium on, or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 

(e) 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
any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of, premium on, or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or
to perform or comply with any other Guaranteed Obligation, each Guarantor promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the holders or the Trustee an amount equal to the sum of
(A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to
the holders and the Trustee. 
 (f) Each Guarantor further agrees that, as between it, on the one hand, and the holders and the Trustee, on
the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 hereof for the purposes of such Guarantor’s Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6 hereof, such Guaranteed Obligations (whether or not
due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 10.01. 

  
 84 

 (g) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable
attorneys’ fees and expenses) incurred by the Trustee or any holder in enforcing any rights under this Section 10.01. 
 SECTION
10.02 Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that
can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

SECTION 10.03 Successors and Assigns. This Article 10 shall be binding upon each Guarantor and its 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 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. 

SECTION 10.04 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 10 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 10 at law, in equity, by statute or otherwise. 

SECTION 10.05 Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure
by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No
notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

SECTION 10.06 Release of Guarantor. A Guarantor shall be released from its obligations under this Article 10 (other than any obligation
that may have arisen under Section 10.07 hereof) without the consent of any holders: 
 (a) in connection with any sale or other disposition
of all or substantially all of the properties or assets of that Guarantor, by way of consolidation, amalgamation, plan of arrangement, merger or otherwise, to a Person that is not (either before or after giving effect to such transaction) the
Company or any Restricted Subsidiary, if the sale or other disposition does not violate Section 4.07 hereof; 
 (b) in connection
with any sale or other disposition of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or any Restricted Subsidiary, if the sale or other disposition does not violate
Section 4.07 hereof and the Guarantor ceases to be a Restricted Subsidiary as a result of the sale or other disposition; 

  
 85 

 (c) if the Company designates that Guarantor to be an Unrestricted Subsidiary in
accordance with the applicable provisions of this Indenture; or 
 (d) upon legal defeasance, covenant defeasance or satisfaction and
discharge of this Indenture as provided under Article 8 hereof. 
 At the request of the Company, and the delivery to the Trustee of an
Officer’s Certificate stating that all conditions precedent to such release have been satisfied, the Trustee shall execute and deliver an appropriate instrument evidencing such release. 

SECTION 10.07 Contribution. Each Guarantor that makes a payment under its Note Guarantee shall be entitled upon payment in full of all
Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of
such payment determined in accordance with IFRS. 
 ARTICLE 11 

SATISFACTION AND DISCHARGE 

SECTION 11.01 Satisfaction and Discharge. 

(a) This Indenture will be discharged and will cease to be of further effect as to all Securities issued thereunder (except as to surviving
rights of registration of transfer or exchange of the Securities and as otherwise specified in this Indenture), when: 
  

	 	(1)	 either: 

  

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

 

	 	(B)	 all Securities that have not been delivered to the Trustee for cancellation have become due and payable by
reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the
benefit of the holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient in the opinion of a nationally recognized investment bank,
appraisal firm or firm of independent public accountants, without consideration of any reinvestment of interest, to pay and discharge the entire 

  
 86 

	 	
Indebtedness on the Securities not delivered to the Trustee for cancellation for principal of, premium on, if any, or interest, if any, on, the Securities to the date of stated maturity or
redemption; 

  

	 	(2)	 the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to
which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and
any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings); 

  

	 	(3)	 the Company or any Guarantor has paid or caused to be paid all sums then due and payable by the Company under
this Indenture; and 

  

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

 (b) In connection with any
discharge under this Article 11, the Company must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Depositary.

fact); and 

  

	 	(4)	 a statement as to whether or not, in the opinion of such individual, such covenant or condition has been
complied with. 

 SECTION 12.06 When Securities are Disregarded. In determining whether the holders of the required
principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall
be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in conclusively relying on any such direction, waiver or consent, only Securities which a Trust Officer actually
knows are so owned shall be so disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination. 

SECTION 12.07 Consent to Jurisdiction and Service of Process. The Company and each Guarantor hereby appoints CT Corporation Systems
which, on the date hereof, is located at 111 Eight Avenue, New York, NY 10011, as the authorized agent thereof (the “Authorized Agent”) upon whom process may be served in any action, suit or proceeding arising out of or based on
this Indenture or the Securities which may be instituted in the Supreme Court of the State of 

  
 89 

 
New York or the United States District Court for the Southern District of New York, in either case in The Borough of Manhattan, The City of New York, by the holder of any Security, and to the
fullest extent permitted by applicable law, the Company and each Guarantor hereby waives any objection which it may now or hereafter have to the laying of venue of any such proceeding and expressly and irrevocably accepts and submits, for the
benefit of the holders from time to time of the Securities, to the nonexclusive jurisdiction of any such court in respect of any such action, suit or proceeding, for itself and with respect to its properties, revenues and assets. Such appointment
shall be irrevocable unless and until the appointment of a successor authorized agent for such purpose, and such successor’s acceptance of such appointment, shall have occurred. The Company and each Guarantor agrees to take any and all actions,
including the filing of any and all documents and instruments that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent with respect to any such action shall be deemed, in
every respect, effective service of process upon the Company or the applicable Guarantor, as the case may be. Notwithstanding the foregoing, any action against the Company or any Guarantor arising out of or based on any Security may also be
instituted by the holder of such Security in any court in the jurisdiction of organization of the Company and each Guarantor, and the Company and each Guarantor expressly accepts the jurisdiction of any such court in any such action. The Company and
each Guarantor shall require the Authorized Agent to agree in writing to accept the foregoing appointment as agent for service of process. 

SECTION 12.08 Waiver of Immunity. To the extent that the Company, any Guarantor or any of their respective properties, assets or
revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any thereof, from set off
or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the
giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this
Indenture or the Securities, the Company and each Guarantor, to the maximum extent permitted by law, hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement. 

SECTION 12.09 Rules by Trustee, Paying Agent and Registrar. The Trustee may make reasonable rules for action by or a meeting of
Securityholders. The Registrar and the Paying Agent may make reasonable rules and set reasonable requirements for their functions. 

SECTION 12.10 Days Other than Business Days. If a payment date is not a Business Day, payment shall be made on the next succeeding day
that is a Business Day, and no interest shall accrue for the intervening period. If a regular record date is not a Business Day, the record date shall not be affected. 

SECTION 12.11 Governing Law. This Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the
State of New York without regard to conflicts of laws principles thereof. 

  
 90 

 SECTION 12.12 No Recourse Against Others. No director, officer, employee,
incorporator or stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Securities, this Indenture or the Note Guarantees or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each holder of Securities by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities. The waiver may not be
effective to waive liabilities under U.S. federal or Canadian securities laws. 
 SECTION 12.13 Successors. All agreements of the
Company and each Guarantor in this Indenture and the Securities shall bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. 

SECTION 12.14 Severability. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 12.15
Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Indenture. The exchange of
copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes.
Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 

SECTION 12.16 Table of Contents; Headings. The table of contents and headings of the Articles and Sections of this Indenture have been
inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof. 

SECTION 12.17 WAIVER OF JURY TRIAL. THE COMPANY, THE GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

SECTION 12.18 USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the
Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship or
opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act. 

SECTION 12.19 Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its
obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation strikes, work 

  
 91 

 
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under
the circumstances. 
 SECTION 12.20 Tax Matters. Each of the Company and the Trustee agrees to cooperate and to provide the other
with such information as each may have in its possession to enable the determination of whether any payments pursuant to this Indenture are subject to the withholding requirements described in Section 1471(b) of the Code or otherwise imposed
pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof. 

SECTION 12.21 Conversion of Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under
this Indenture to the holder from U.S. dollars to another currency, the Company and each Guarantor has agreed, and each holder by holding such Security will be deemed to have agreed, to the fullest extent that the Company, each Guarantor and they
may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the
day on which final judgment is given. 
 The Company’s and Guarantors’ obligations to any holder will notwithstanding any judgment
in currency (the “Judgment Currency”) other than U.S. dollars be discharged only to the extent that on the Business Day following receipt by such holder or the Trustee as the case may be, of any amount in such Judgment Currency,
such holder may in accordance with normal banking procedures purchase U.S. dollars with the judgment currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid to such holder or the Trustee in the Judgment
Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Company and the Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the
holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such holder or the Trustee, as the case may be, such holder or the Trustee, as the
case may be, will pay the Company and the Guarantors, such excess; provided that such holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as any Default under the Securities or this
Indenture has occurred and is continuing or if the Company or the Guarantors shall have failed to pay any holder or the Trustee any amounts then due and payable under such Security or this Indenture in which case such excess may be applied by such
holder or the Trustee to such Obligations.

 PRIVATE RESALE APPENDIX 

PROVISIONS RELATING TO SECURITIES 

1. The Securities. 
 1.1
(a) Form and Dating. The Securities authenticated on the Amendment Date will be held by IAIs. The Securities may be transferred only to (i) QIBs in reliance on Rule 144A under the Securities Act (“Rule 144A”); (ii)
non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act (“Regulation S”); and (iii) IAIs in reliance on other exemptions from registration under the Securities Act, in each case, subject
to the restrictions on transfer set forth herein and all other applicable securities laws, including Applicable Securities Laws. (i) The Securities shall be issued initially in the form of one or more permanent global Securities in definitive,
fully registered form (collectively, the “IAI Global Security”); (ii) any Securities resold pursuant to Rule 144A shall be represented by a global security in fully registered form (the “Rule 144A Global Security”);
and (iii) any Securities resold pursuant to Regulation S shall be represented by a global security in fully registered form (the “Regulation S Global Security” and, together with the IAI Global Security and the 144A
Global Security, the “Global Securities”), in each case without interest coupons and with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto, which shall be deposited on
behalf of the purchasers of the Securities represented thereby with the Securities Custodian and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in
the Indenture. 
 Beneficial interests in a Global Security may be exchanged for interests in another Global Security if the transferor of
the beneficial interest in the Global Security first delivers to the Trustee a written certificate (in the form set forth on the reverse of the Security) to the effect that such transfer is being made pursuant to the relevant exemption from
registration under the Securities Act. 
 The aggregate principal amount of the Global Securities may from time to time be increased or
decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided, including to reflect PIK Payments and to reflect any increase pursuant to paragraph 2 of the Security. 

(b)    Book-Entry Provisions. This Section 1.1(b) shall apply only to a Global Security deposited with or on
behalf of the Depositary. 
 The Company shall execute and the Trustee shall, in accordance with this Section 1.1(b) and
Section 1.2 hereof, authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary and
(b) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the Trustee as custodian for the Depositary. 

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any
Global Security held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the
Depositary 

  
 A-1 

 
as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the
exercise of the rights of a holder of a beneficial interest in any Global Security. 
 (c) Definitive Securities. Except as provided
in Section 1.3 or 1.4 hereof, owners of beneficial interests in Global Securities shall not be entitled to receive physical delivery of Definitive Securities. 

(d) PIK Payments. For the Interest Period starting from the Amendment Date and ending on July 15, 2020 (the “Initial Interest
Period”) and if the Company exercises the PIK Option with respect to any other Interest Period, the Company shall pay the applicable amount of PIK Interest for such Interest Period in respect of each outstanding Security on the Interest
Payment Date in respect of such Interest Period by increasing the principal amount of each such outstanding Security at the end of such Interest Period by an amount equal to the PIK Interest applicable to each such outstanding Security (rounded up
to the nearest whole U.S. dollar), and an adjustment shall be made by the Trustee to reflect such increase, with respect to Global Securities, in the “Schedule of Increases or Decreases in Global Security” and, with respect to
Definitive Securities, on the books and records of the Trustee (a “PIK Payment”). Following any increase in the principal amount of the outstanding Securities as a result of a PIK Payment, the Securities will bear interest on such
increased principal amount from and after the date of such PIK Payment. Unless the context otherwise requires, for all purposes under this Indenture (including for purposes of calculating any redemption price or redemption amount), references to the
“principal” and the “principal amount” of any Securities includes any increase in the principal amount thereof due to the addition of PIK Interest thereto as a result of any PIK Payment. If the Company desires to exercise the PIK
Option with respect to an Interest Period, the Company must deliver a notice to the Trustee no later than the day that is five (5) Business Days prior to the Interest Payment Date for such Interest Period, which notice indicates (x) that
the PIK Option is being exercised for such Interest Period and (y) the amount of PIK Interest that will be paid in respect of such Interest Period on such Interest Payment Date (such notice, a “PIK Notice”). For the avoidance
of doubt, no PIK Notice is required to be delivered to the Trustee with respect to the Initial Interest Period. 
 1.2
Authentication. The Trustee (1) authenticated and delivered on the Issue Date, an aggregate principal amount of US$160,000,000 of 9.00% Senior Notes due 2022 (the “Existing Securities”), (2) shall authenticate and
deliver on the Amendment Date, an aggregate principal amount of US$112,000,000 of 12.00% Senior PIK Toggle Notes due 2024 which shall amend and restate in their entirety and without novation the Existing Securities, and (3) shall execute and
deliver any Additional Securities for an original issue in an aggregate principal amount specified in the written order of the Company pursuant to Section 2.02 of the Indenture. Such 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, in the case of any issuance of Additional Securities pursuant to Section 2.13 of the Indenture, shall certify that such issuance is in compliance with
Section 4.05 of the Indenture. 

  
 A-2 

 1.3 Transfer and Exchange. 

(a) Transfer and Exchange of Definitive Securities. When Definitive Securities are presented to the Registrar with a request: 

 

	 	(x)	 to register the transfer of such Definitive Securities; or 

 

	 	(y)	 to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other
authorized denominations, 

 the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements
for such transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange: 
  

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

  

	 	(ii)	 if such Definitive Securities are required to bear a restricted securities legend, they are being transferred
or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 1.3(b) hereof or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and
documents, as applicable: 

  

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

interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred. 

 

	 	(iii)	 Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 1.4

a successor Depositary or a nominee of such successor Depositary. 

  

	 	(iv)	 In the event that a beneficial interest in a Global Security is exchanged for Definitive Securities pursuant to
Section 1.4 hereof, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 1.3 (including the certification requirements set forth on the reverse of the
Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by

 [FORM OF REVERSE SIDE OF SECURITY] 

12.00% Senior PIK Toggle Notes due 2024 
 1.
Interest 
 Hammerhead Resources Inc. (f/k/a Canadian International Oil Corp.), a corporation incorporated under the Business
Corporations Act (Alberta) (the “Company”) and its successors and assigns under the Indenture hereinafter referred to, promises to pay with respect to each Interest Period (other than for the Interest Period ending on but excluding
July 15, 2020 (the “Initial Interest Period”)) interest on the principal amount of this Security in cash or, with respect to any Interest Period with respect to which the Company exercises the PIK Option, in PIK Interest, at a
rate per annum equal to 12.00%. 
 For the Initial Interest Period, the Company promises to pay an aggregate of US$970,667.00 in PIK
Interest on the principal amount of this Security on July 15, 2020. 
 Following the Initial Interest Period, for any other Interest
Period, the Company, in its sole discretion, may elect to pay 100% of the interest with respect to such Interest Period in kind (the “PIK Option”). In the event that the Company exercises the PIK Option with respect to any Interest
Period, the Company promises to pay with respect to such Interest Period interest in kind on the principal amount of this Security at a rate per annum equal to 12.00%. 

For purposes of this Security and the Indenture, (x) the interest that is payable in kind in respect of the Initial Interest Period and
any other Interest Period in which the Company exercises the PIK Option is referred to as “PIK Interest” and (y) “Interest Period” means the period commencing on and including an Interest Payment Date and ending on
but excluding the next succeeding Interest Payment Date, it being understood that the Initial Interest Period commenced on and includes the Amendment Date, and ends on and excludes July 15, 2020. 

In the event that the Company elects to exercise the PIK Option with respect to any Interest Period, it shall deliver a PIK Notice to the
Trustee no later than the day that is five (5) Business Days prior to the Interest Payment Date for such Interest Period, which PIK Notice indicates (x) that the PIK Option is being exercised for such Interest Period and (y) the
amount of PIK Interest that will be paid on such Interest Payment Date. The Company shall be deemed to have exercised the PIK Option with respect to any Interest Period if it delivers a PIK Notice for such Interest Period in accordance with the
immediately preceding sentence and will be deemed to not have exercised a PIK Option for any Interest Period if it does not deliver a PIK Notice with respect to such Interest Period in accordance with the immediately preceding sentence. For the
avoidance of doubt, no PIK Notice is required to be delivered to the Trustee with respect to the Initial Interest Period. 
 The Company
shall pay the applicable amount of any PIK Interest for any applicable Interest Period in respect of this Security on the Interest Payment Date in respect of such Interest Period by increasing the principal amount of this Security at the end of such
Interest Period by the amount of such PIK Interest (rounded up to the nearest whole U.S. dollar) and the Company shall otherwise follow the procedures relating to the payment of PIK Interest described in the Indenture and the Private Resale Appendix
Following any increase in the principal amount of this Security 

  
 A1-5 

 
as a result of a PIK Payment, this Security will bear interest on such increased principal amount from and after the date of such PIK Payment. Unless the context otherwise requires, for all
purposes under this Indenture (including for purposes of calculating any redemption price or redemption amount), references to the “principal” and the “principal amount” of any Securities includes any increase in the principal
amount thereof due to the addition of PIK Interest thereto as a result of any PIK Payment. 
 The Company shall pay interest semiannually on
July 15 and January 15 of each year or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). The Interest Payment Date with respect to Initial Interest Period shall
be July 15, 2020. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance. Interest will be computed on the basis of a 360-day year of twelve 30-day months. For purposes of disclosure pursuant to the Interest Act (Canada), the annual rate of interest to which the rate of interest
provided on this Security is equivalent is the rate so determined multiplied by the actual number of days in the applicable calendar year and divided by 360. 

Notwithstanding anything to the contrary and for the avoidance of doubt, (a) the payment of any accrued and unpaid interest in connection
with any redemption or repurchase of Securities pursuant to Article 3 of the Indenture, paragraph 5(b) of the Securities, Section 4.07 of the Indenture or Section 4.09 of the Indenture, as applicable, (b) the payment of any accrued
and unpaid interest in connection with any defeasance or satisfaction and discharge of the Indenture, (c) the payment of any accrued and unpaid interest on the maturity date of the Securities and (d) the payment of any accrued and unpaid
interest upon any acceleration of the Securities shall, in each case of clauses (a), (b), (c) and (d), be made solely in cash. 
 2. Method of
Payment 
 Except as provided in paragraph 1 above, the Company shall pay interest on the Securities (except defaulted interest) to the
Persons who are registered holders of Securities at the close of business on the July 1 or January 1 next preceding the Interest Payment Date even if Securities are canceled after the record date and on or before the Interest Payment Date.
Holders must surrender Securities to a Paying Agent to collect principal payments. Except as provided in paragraph 1 above with respect to PIK Interest, the Company shall pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts. Except as provided in paragraph 1 above with respect to PIK Interest, payments in respect of the Securities represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Except as provided in paragraph 1 above with respect to PIK Interest, the Company shall make all payments in respect of a certificated Security
(including principal, premium and interest) by mailing a check to the registered address of each holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding
the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 

  
 A1-6 

 3. Paying Agent and Registrar 

Initially, Computershare Trust Company, N.A. (the “Trustee”) will act as Paying Agent and Registrar and transfer agent. The
Company may appoint and change any Paying Agent, Registrar, co-registrar or transfer agent without notice. The Company or any of the Guarantors may act as Paying Agent, Registrar or co-registrar. 
 4. Indenture 

The Company issued the Securities under an indenture, dated as of July 10, 2017 (as amended and restated on June 19, 2020 and as
further amended or supplemented from time to time, the “Indenture”), among the Company, the Guarantors from time to time party thereto and the Trustee. Terms defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of those terms. 

The Securities are unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.05 of
the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Securities issued on the Amendment Date and any Additional Securities will be treated as a single class for all purposes under the Indenture. The
Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; issue or sell capital stock of
subsidiaries; engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of subsidiaries; and consolidate, merge or transfer all or substantially all of their
assets and the assets of their subsidiaries. These covenants are subject to important exceptions and qualifications. 
 5. Optional Redemption 

(a) If the Required Equity Investments are made on or before September 30, 2020, the Company may redeem up to US$24.0 million in
aggregate principal amount of Securities (upon not less than ten days’ notice following the making of such Required Equity Investments) at an aggregate redemption price of US$1.00, plus accrued and unpaid interest, if any, on the Securities
redeemed, to, but not including, the applicable date of redemption. For the avoidance of doubt, any such accrued and unpaid interest payable on the Securities redeemed pursuant to this paragraph 5(a) shall be payable in PIK Interest. 

(b) On or after the Amendment Date, the Company may on any one or more occasions redeem all but not less than all of the Securities then
outstanding, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest, if any, on the Securities redeemed, to, but not
including, the applicable date of redemption. 
 (c) Unless the Company defaults in the payment of the redemption price, interest will cease
to accrue on the Securities or portions thereof called for redemption on the applicable redemption date. Any redemption may, at the Company’s discretion, be subject to any one or more of the following conditions precedent, (i) completion
of a Change of Control, (ii) completion of an Equity Offering and (iii) the incurrence of Indebtedness referred to in Section 4.05(b)(15) of the Indenture. 

  
 A1-7 

 (d) If the Securities are accelerated or otherwise become due prior to their maturity date,
in each case, as a result of an Event of Default on or after the Amendment Date, the amount of principal of, accrued and unpaid interest and premium on the Securities that becomes due and payable shall equal the redemption price applicable with
respect to an optional redemption of the Securities, in effect on the date of such acceleration as if such acceleration were an optional redemption of the Securities accelerated. 

(e) If the optional redemption date is on or after an interest record date and on or before the related Interest Payment Date, the accrued and
unpaid interest on the Securities, if any, will be paid to the Person in whose name the Security is registered at the close of business on such record date, and no additional interest will be payable to holders whose Securities will be subject to
redemption by the Company. 
 (f) The Company shall cause notice of such redemption to be sent to each holder of Securities to be redeemed
not less than 30 nor more than 60 days prior to the redemption date, except (i) in the case of the redemption set out in paragraph 5(a) above and (ii) that redemption notices issued in connection with a defeasance of the Securities or a
satisfaction or discharge of the Indenture may be sent more than 60 days prior to the redemption date. 
 6. Notice of Redemption 

Notice of redemption will be sent to holders of Securities as set forth in paragraph 5 of the Securities to each holder of Securities to be
redeemed at his registered address. Securities in denominations larger than US$1.00 principal amount may be redeemed in part but only in whole multiples of US$1.00. If money sufficient to pay the redemption price of and accrued interest on all

Securities (or such portions thereof) called for redemption. 
 7. Mandatory Redemption 

The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities. However, under certain
circumstances, the Company may be required to offer to purchase the Securities in accordance with Section 4.09 of the Indenture. The Company may acquire Securities by means other than a redemption, whether by tender offer, open market
purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture. 

8. Put Provisions 
 Upon a Change of
Control, any holder of Securities will have the right to require the Company to repurchase all or any part of the Securities of such holder at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued
interest to the date of repurchase (subject to the right of holders of record on the relevant record date to receive 

  
 A1-8 

 
interest due on the related Interest Payment Date) as provided in, and subject to the terms of, the Indenture. In addition, in the event of certain Asset Dispositions, the Company may be required
to use the proceeds thereof to make an offer to the holders to purchase Securities at a purchase price of 101% of their principal amount, plus accrued but unpaid interest, in accordance with the procedures set forth in the Indenture. 

9. Guarantee 
 The payment by the Company
of the principal of, and premium and interest on, the Securities and other obligations under the Indenture is fully and unconditionally guaranteed on a joint and several senior basis by each of the Guarantors to the extent set forth in the
Indenture. 
 10. Denominations; Transfer; Exchange 

The Securities are in registered form without coupons in denominations of US$1.00 principal amount and integral multiples of US$1.00 in excess
thereof. A holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
 11. Persons Deemed Owners 

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

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

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and
the Indenture if the Company deposits with the Trustee sufficient money or U.S. Government Obligations (as certified by an independent firm of certified public accountants) for the payment of principal and interest on the Securities to redemption or
maturity, as the case may be. 
 14. Amendment; Waiver 

Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of
the holders of a majority in principal amount of the then-outstanding Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the holders of a majority in principal amount of the
then-

  
 A1-9 

 
outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any holder of Securities, the Company, the Guarantors and the Trustee shall be entitled to
amend the Indenture and the Securities to cure any ambiguity, defect or inconsistency, or to comply with Article 5 of the Indenture, or to make a change that would provide additional rights or benefits to holders or that does not adversely affect
the legal rights under the Indenture of any holder, or to provide for the issuance of additional Securities in accordance with the limitations set forth in the Indenture as of the date of the Indenture, or to secure the Securities or the Note
Guarantees pursuant to Section 4.10 of the Indenture, or to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, or to evidence or provide for the acceptance of appointment under the Indenture of a
successor trustee. 
 15. Defaults and Remedies 

Under the Indenture, Events of Default include: (a) default for 30 days in payment of interest on the Securities; (b) default in
payment of principal on the Securities at maturity, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company
or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (d) failure by the Company or any Restricted Subsidiary for 60 days after receiving notice from the
Trustee or 25% in aggregate principal amount of the Securities to comply with the agreements in the Indenture; (e) certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the
Company, any Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds C$5.0 million; (f) certain judgments or decrees for the payment of money in excess of C$5.0 million; (g) certain defaults with
respect to the Guarantees; and (h) certain events of bankruptcy or insolvency with respect to the Company, the Guarantors and the Significant Subsidiaries. In case of an Event of Default arising from
non-compliance with Section 4.18 of the Indenture, the Trustee or any affected holder may declare all the Securities to be due and payable immediately by notice in writing to the Company specifying the
Event of Default. If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default. 

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, the holders of a majority in principal amount of the then-outstanding Securities may direct the Trustee in its exercise of any
trust or power. Subject to certain exceptions set forth in this Indenture, the Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice
is not opposed to the interest of the holders. 
 16. Trustee Dealings with the Company 

Subject to certain limitations imposed by the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

  
 A1-10 

 17. No Recourse Against Others 

A director, officer, employee, incorporator or equityholder, as such, of the Company or any Guarantor shall not have any liability for any
obligations of the Company under the Securities or the Indenture or of any Guarantor under its Note Guarantee or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. By accepting a Security,
each Securityholder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Securities. 

18. Authentication 
 This Security shall
not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security. 

19. Abbreviations

 20. CUSIP and ISIN Numbers

numbers to be printed on the Securities and have directed the Trustee to use CUSIP and ISIN numbers in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the
Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least US$250,000 principal amount of the Securities (or, if less than
US$250,000, we are furnishing herewith an Opinion of Counsel that such purchase is in compliance with the Securities Act), and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation
of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities

that the Company and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clause (iii) or (iv) above to require the delivery of an opinion of
counsel, certifications or other information satisfactory to the Company and the Trustee.
