EXHIBIT 10.7

 

SPRING BANK PHARMACEUTICALS, INC.

RETENTION AND BONUS AWARD AGREEMENT

This Retention and Bonus Award Agreement (this “Agreement”) is made and entered into on _________, 2020 (the “Effective Date”), between Spring Bank Pharmaceuticals, Inc. (the “Company”) and ______________ (“Employee”).

WHEREAS, Employee occupies a key position with the Company and in order to ensure the continued effective conduct of the Company’s business, the Company desires to assure itself of the continuous services of Employee;

WHEREAS, Employee is a party to an employment agreement with the Company dated ______ (as amended, the “Employment Agreement”); 

WHEREAS, on July 29, 2020, the Company entered into a Share Exchange Agreement with F-star Therapeutics Limited (“F-star”), pursuant to which the Company will acquire all of the issued and outstanding share capital of F-star, with F-star remaining as the surviving company (the “Transaction”); and

WHEREAS, the Company desires to offer Employee a retention bonus award in an amount equal to $15,000 upon the closing of the Transaction (the “Closing”).

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, the parties hereby agree as follows:

	
1.
	
Retention Award.  In the event that the Employee remains continuously employed by the Company between the Effective Date and the Closing, then Employee shall be eligible to receive a retention award in the amount of $15,000 (the “Retention Award”).  If the Closing does not occur by March 31, 2021, this Agreement shall terminate in full without any further liability to the Company.  The Retention Award shall be paid in a single lump sum on or within thirty (30) days following the Closing.

	
2.
	
Termination of Employment.  Employee shall no longer be eligible for any portion of the Retention Award if Employee’s employment is terminated for any reason prior to the Closing; provided, however, that if the Company terminates Employee’s employment without Cause (as defined in the Employment Agreement) or Employee resigns from employment with Good Reason (as defined in the Employment Agreement) prior to the Closing, the Company shall pay Employee the Retention Award in a single lump sum on or within thirty (30) days following Employee’s termination of employment. 

	
3.
	
Exclusion for Analogous Retention Benefits; No Effect on Severance and Other Benefits. An employee who is eligible for retention payments or benefits under any analogous retention plan, policy or agreement with the Company shall not be eligible for or entitled to receive this Agreement or any payment or benefit hereunder. This Agreement, however, shall not affect Employee’s eligibility or entitlement to receive any benefits payable (i) to Employee under another severance or change of control plan, policy or agreement with the Company or (ii) to Employee under that certain Retention Award Agreement between Employee and the Company dated March 5, 2020.

 

 

	
4.
	
Other Rights and Agreements.  This Agreement does not create any employment rights not specifically set forth herein with respect to Employee.  Employee’s employment remains at-will and can be terminated by the Company at any time and for any reason, with or without Cause.  This Agreement contains the entire understanding of the Company and Employee with respect to the subject matter hereof.

	
5.
	
Confidentiality. Employee agrees and covenants that, except as required by applicable law, Employee shall not disclose, reveal, publish, disseminate, or discuss, directly or indirectly, to or with any other person or entity the terms of this Agreement other than his or her immediate family, lawyer and tax advisor and that any such disclosure, revelation, publication, dissemination or discussion shall result in the immediate forfeiture of the entire Retention Award. 

	
6.
	
Taxation; Section 409A. All payments described herein shall be subject to any and all applicable federal, state, local, foreign and/or other withholding taxes and all other authorized payroll deduction. This Agreement is intended to either comply with or be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and final regulations, rulings and other applicable guidance issued thereunder (collectively, “Section 409A”), and shall be interpreted and administered accordingly.  For purposes of Section 409A, references to termination of employment shall, to the extent any payments hereunder are not exempt from Section 409A, be interpreted consistent with the definition of “separation from service” in Section 409A (after giving effect to the presumptions contained therein). If at the time of Employee’s termination, Employee is deemed to be a “specified employee” of the Company under Section 409A, then limited only to the extent necessary to comply with the requirements of Section 409A, any payments which are subject to Section 409A (and not otherwise exempt from its application) shall be withheld until the 1st business day of the 7th month following the termination of Employee’s employment, at which time Employee shall be paid an aggregate amount equal to the accumulated but unpaid payments otherwise due to Employee. It is intended that each installment of the payments provided in this Agreement shall be treated as a separate “payment” under Section 409A.  Neither the Company nor Employee shall have the right to accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A. Employee may not designate the taxable year of the Retention Award.  Employee acknowledges that the Company does not guarantee the tax treatment or tax consequences associated with any payment provided in this Agreement, including but not limited to under Section 409A.

	
7.
	
General.  This Agreement may be amended only by written agreement signed by the Company and Employee. This Agreement shall be binding on the Employee and Employee’s executor, administrator and heirs, but may not be assigned by Employee.  This Agreement may be transferred or assigned by the Company and shall be binding on the transferee or assignee.  This Agreement shall automatically be transferred or assigned to and be binding upon any successor in interest to the Company, whether by merger, consolidation, sale of stock, sale of assets or otherwise.  This Agreement shall be construed and enforced in accordance with the laws of Massachusetts, without giving effect to the principles of conflict of laws thereof.

by the holder of its Equity Interests at such time.

 -30- 

 (6) references to sections of or rules under the Securities
Act shall be deemed to include substitute, replacement of successor sections or rules adopted by the Commission from time to time; 

(7) When calculating the availability under any basket or ratio under this Indenture, in each case in
connection with a Limited Condition Transaction and other transactions in connection therewith (including any incurrence or issuance of Indebtedness, Disqualified Stock or Preferred Equity Interests and the use of proceeds thereof, the incurrence of
any Lien or the making of any Investment or any Restricted Payments), the date of determination of such basket or ratio and of any Default or Event of Default may, at the Issuer’s option, be the date the definitive agreement(s) for such Limited
Condition Transaction is entered into. Any such ratio or basket shall be calculated on a pro forma basis after giving effect to such Limited Condition Transaction and other transactions in connection therewith (including any incurrence or
issuance of Indebtedness, Disqualified Stock or Preferred Equity Interests and the use of proceeds thereof, the incurrence of any Lien or the making of any Investment or any Restricted Payments) as if they had been consummated at the beginning of
the applicable period for purposes of determining the ability to consummate any such Limited Condition Transaction; provided that if the Issuer elects to make such determination as of the date of such definitive agreement(s), then
(x) the Issuer shall be deemed to be in compliance with such ratios or baskets solely for purposes of determining whether the Limited Condition Transaction and other transactions in connection therewith (including any incurrence or issuance of
Indebtedness, Disqualified Stock or Preferred Equity Interests and the use of proceeds thereof, the incurrence of any Lien or the making of any Investment or any Restricted Payments), is permitted under the applicable covenants, and (y) such
ratios or baskets shall not be tested at the time of consummation of such Limited Condition Transaction or related transactions; provided, further, that if the Issuer elects to have such determinations occur at the time of entry into
such definitive agreement(s), any such transactions (including any incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and the use of proceeds thereof, the incurrence of any Lien or the making of any Investment or any
Restricted Payments) shall be deemed to have occurred on the date the definitive agreement(s) is entered into and shall be deemed outstanding thereafter for purposes of calculating any ratios or baskets under this Indenture after the date of such
definitive agreement(s) and before the consummation of such Limited Condition Transaction, unless such definitive agreement(s) is terminated or such Limited Condition Transaction or incurrence or issuance of Indebtedness, Disqualified Stock or
Preferred Equity Interests, Restricted Payment, Investment or incurrence of Liens or such other transaction to which pro forma effect is being given does not occur; 

(8) For purposes of calculating any ratio-based basket, with respect to any revolving Indebtedness incurred
under such ratio-based basket, the Issuer may elect (which election may not be changed with respect to such Indebtedness), at any time, to either (x) give pro forma effect to the incurrence of the entire committed amount of such
Indebtedness, in which case such committed amount may thereafter be borrowed or reborrowed, in whole or in part, from time to time, without further compliance with any ratio-based component of any provision of this Indenture, or (y) give pro
forma effect to the incurrence of the actual amount drawn under such revolving Indebtedness, in which case, the ability to incur the amounts committed to under such Indebtedness will be subject to such ratio-based basket (to the extent being
incurred pursuant to such ratio) at the time of each such Incurrence. To the extent clause (x) of the immediately preceding sentence is elected, such revolving Indebtedness shall be deemed to be incurred (and the fully committed amount of
Indebtedness as outstanding) at all times thereafter for purposes of testing any ratio-based baskets, regardless of whether such Indebtedness is outstanding, until such commitments have been permanently terminated in full; and 

(9) Notwithstanding anything herein the contrary, unless the Issuer elects otherwise, if, on any date, the
Issuer or any of its Restricted Subsidiaries in connection with any transaction or series of related transactions (A) utilizes a ratio-based basket under a covenant and (B) utilizes a non-ratio-based
basket under the same covenant, then the applicable ratio-based basket under such covenant will be calculated on such date with respect to any usage under the applicable ratio-based basket under such covenant without giving effect to the usage under
such non-ratio based basket under the same such covenant made in connection with such transaction or series of related transactions.

to Section 2.05 hereof) prior to such first solicitation or vote, as the case may be. With regard to any record date, only the Holders on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant
action.

SECTION 2.02 Form of Execution and Authentication. 

An Officer shall sign the Notes for the Issuer by manual, electronic or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time the Note is authenticated, the Note shall
nevertheless be valid. 
 A Note shall not be valid until authenticated by the manual signature of the Trustee. The
signature of the Trustee shall be conclusive evidence that the Note has been authenticated under this Indenture. All notes shall be dated the date of their authentication. 

The Trustee shall authenticate (i) Initial Notes for original issue on the Issue Date in an aggregate principal amount of
$400.0 million and (ii) subject to compliance with Section 4.09 hereof, one or more series of Notes for original issue after the Issue Date (such Notes to be substantially in the form of Exhibit A) in an
unlimited amount, in each case upon written order of the Issuer in the form of an Officers’ Certificate, which Officers’ Certificate shall, in the case of any issuance pursuant to clause (ii) above, certify that such issuance is in
compliance with Section 4.09 hereof. In addition, each such Officers’ Certificate shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated, whether the securities are to be Initial Notes or
Notes issued under clause (ii) of the preceding sentence and the aggregate principal amount of Notes outstanding on the date of authentication, and shall further specify the amount of such Notes to be issued as Global Notes or Definitive Notes.
Such Notes shall initially be in the form of one or more Global Notes, which (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Notes to be issued, (ii) shall be registered in the
name of the Depositary or its nominee and (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction. All Notes issued under this Indenture shall vote and consent together on all matters as one
class and no series of Notes will have the right to vote or consent as a separate class on any matter; provided, however, that no additional Notes will be issued with the same CUSIP or ISIN as the Initial Notes unless the Issuer intends to
treat such additional Notes and the Initial Notes as fungible for U.S. and Canadian federal income tax purposes. 
 In
authenticating Notes other than the Initial Notes, and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall receive, and, subject to Section 7.01, shall be fully protected in relying upon:

  

	 	(a)	 A copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and form
of the Notes were established, certified by the Secretary or an Assistant Secretary of the Issuer to have been duly adopted by the Board of Directors and to be in full force and effect as of the date of such certificate, and if the terms and form of
such Notes are established by an Officers’ Certificate pursuant to general authorization of the Board of Directors, such Officers’ Certificate; 

  

	 	(b)	 an executed supplemental indenture, if any; 

 

	 	(c)	 an Officers’ Certificate delivered in accordance with Section 12.04; and 

 

	 	(d)	 an Opinion of Counsel delivered in accordance with Section 12.04 and which shall state:

  
 -34- 

	 	(1)	 that the form of such Notes has been established by a supplemental indenture or by or pursuant to a
resolution of the Board of Directors in accordance with Sections 2.01 and 2.02 and in conformity with the provisions of this Indenture; 

  

	 	(2)	 that the terms of such Notes have been established in accordance with Section 2.01 and in conformity
with the other provisions of this Indenture; and 

  

	 	(3)	 that such Notes, when authenticated and delivered by the Trustee and issued by the Issuer in the manner and
subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Issuer, 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. 

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Notes 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
an Agent to deal with the Issuer or any Affiliate of the Issuer. 
 SECTION 2.03 Registrar and Paying
Agent. 
 The Issuer shall maintain (i) an office or agency where Notes may be presented for
registration of transfer or for exchange (including any co-registrar, the “Registrar”) and (ii) an office or agency where Notes may be presented for payment (“Paying
Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term
“Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent, Registrar or co-registrar without prior notice to any Holder of a Note. The Issuer shall notify the
Trustee in writing and the Trustee shall notify the Holders of the Notes of the name and address of any Agent not a party to this Indenture. The Issuer may act as Paying Agent, Registrar or co-registrar. The
Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions hereof that relate to such Agent. The Issuer shall notify the Trustee in writing of the name and
address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such, and shall be entitled to appropriate compensation in accordance with Section 7.07
hereof. 
 The Issuer initially appoints the Trustee as Registrar and Paying Agent in connection with the Notes. 

SECTION 2.04 Paying Agent To Hold Money in Trust. 

The Issuer 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 the Holders of the Notes or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, and interest on the Notes, and shall notify the Trustee in writing of any Default by the Issuer in making
any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by such Paying Agent to the Trustee. Upon
payment over to the Trustee, the Paying Agent (if other than the Issuer) shall have no further liability for the money delivered to the Trustee. If the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit
of the Holders of the Notes all money held by it as Paying Agent. Upon the occurrence of any event specified in Section 6.01(i) or Section 6.01(j), the Trustee shall automatically become the Paying Agent. 

SECTION 2.05 Lists of Holders of the Notes. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names
and addresses of Holders of the Notes. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing a list
in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of the Notes, including the aggregate principal amount of the Notes held by each thereof.

 SECTION 2.06 Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Global
Notes will be exchanged by the Issuer for Definitive Notes, subject to any applicable laws, if (i) the Issuer delivers to the Trustee notice from the Depositary that (A) the Depositary is unwilling or unable to continue to act as
Depositary for the Global Notes or (B) the Depositary is no longer a clearing agency registered under the Exchange Act and, in either case, the Issuer fails to appoint a successor Depositary within 90 days after the date of such notice from the
Depositary, (ii) the Issuer in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee or (iii) upon request of
the Trustee or Holders of a majority of the aggregate principal amount of outstanding Notes if there shall have occurred and be continuing a Default or Event of Default with respect to the Notes; provided that in no event shall any temporary
Note that is a Global Note issued pursuant to Regulation S be exchanged by the Issuer for Definitive Notes prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificate identified by the
Issuer and its counsel to be required pursuant to Rule 903 or Rule 904 under the Securities Act. In any such case, the Issuer will notify the Trustee in writing that, upon surrender by the Participants and Indirect Participants of their
interests in such Global Note, certificated Notes will be issued to each Person that such Participants, Indirect Participants and the Depositary jointly identify as being the beneficial owner of the related Notes. Global Notes also may be exchanged
or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or
2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06. However, beneficial interests in a Global Note may
be transferred and exchanged as provided in paragraph (b) or (c) below. 
 (b) Transfer and Exchange of Beneficial
Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions hereof and the Applicable Procedures. Beneficial interests in the
Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth in this Indenture to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also shall require compliance
with the applicable subparagraphs below. 
 (i) Transfer of Beneficial Interests in the Same Global
Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in
the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, no transfer of beneficial interests in a Regulation S Global Note may be made to a U.S. Person or for the account or benefit of a U.S.
Person (other than an Initial Purchaser) unless permitted by applicable law and made in compliance with subparagraphs (ii) and (iii) below. Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery
thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this subparagraph (i) unless specifically
stated above. 
 (ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In
connection with all transfers and exchanges of beneficial interests that are not subject to subparagraph (i) above, the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a written order from a Participant
or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to
be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or, (B) (1) if Definitive Notes are at such time
permitted to be issued pursuant to this Indenture, a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in
an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive

  
 -36- 

 
Note shall be registered to effect the transfer or exchange referred to in (1) above. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global
Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to paragraph (h) below. 

(iii) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any
Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of subparagraph (ii) above and the Registrar
receives the following: 
 (A) if the transferee will take delivery in the form of a beneficial interest in a
144A Global Note, then the transferor must deliver a certificate in the form of Exhibit C hereto, including the certifications in item (1) thereof; and 

(B) if the transferee will take delivery in the form of a beneficial interest in a Regulation S Global Note,
then the transferor must deliver a certificate in the form of Exhibit C hereto, including the certifications in item (2) thereof. 

(iv) Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in
an Unrestricted Global Note. A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of
a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of subparagraph (ii) above, and the Registrar receives the following: 

(A) if the holder of such beneficial interest in a Restricted Global Note proposes to exchange such beneficial
interest for a beneficial interest in an Unrestricted Global Note, a certificate from such holder in the form of Exhibit D hereto, including the certifications in item (1)(a) thereof, or 

(B) if the holder of such beneficial interest in a Restricted Global Note proposes to transfer such beneficial
interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note, a certificate from such holder in the form of Exhibit C hereto, including the applicable certifications in item
(4) thereof;

requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Issuer to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer
contained in this Indenture and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act. 

If any such transfer is effected pursuant to subparagraphs (A) and (B) above at a time when an Unrestricted Global Note
has not yet been issued, the Issuer shall issue and, upon receipt of an authentication order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to
the aggregate principal amount of beneficial interests transferred pursuant to subparagraphs (A) and (B) above. 

Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery
thereof in the form of, a beneficial interest in a Restricted Global Note. 
 (c) Transfer and Exchange of Beneficial
Interests for Definitive Notes.

the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to paragraph

Definitive Note issued in exchange for a beneficial interest in a Restricted Global Note pursuant to this subparagraph (i) shall bear the Private Placement Legend and the Canadian Private Placement Legend (if applicable) and shall be subject to
all restrictions on transfer contained therein. 
 Transfer and Exchange of Beneficial Interests in Restricted Global Notes for
Unrestricted Definitive Notes. A holder of a beneficial interest in a Restricted Global Note may exchange such beneficial interest for an Unrestricted Definitive Note or may transfer such beneficial interest to a Person who takes delivery
thereof in the form of an Unrestricted Definitive Note only if the Registrar receives the following: 
  

	 	A.	 if the holder of such beneficial interest in a Restricted Global Note proposes to exchange such beneficial
interest for a Definitive Note that does not bear the Private Placement Legend, a certificate from such holder in the form of Exhibit D hereto, including the certifications in item (1)(b) thereof; or 

 

	 	B.	 if the holder of such beneficial interest in a Restricted Global Note proposes to transfer such beneficial
interest to a Person who shall take delivery thereof in the form of a Definitive Note that does not bear the Private Placement Legend, a certificate from such holder in the form of Exhibit C hereto, including the applicable certifications in
item (4) thereof,

Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Issuer to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on
transfer contained in this Indenture and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

Indenture unless specifically stated otherwise in the applicable provisions hereof. 
 (i) Private
Placement Legend. 
 Except as permitted by subparagraph (B) below, each Global Note (other than an Unrestricted Global Note) and
each Definitive Note (and all Notes issued in exchange therefor or substitution thereof) shall bear the Private Placement Legend. 

Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraphs (b)(iv), (c)(ii), (c)(iii), (d)(ii),

Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or
for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or 

  
 -41- 

 
by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such
increase. 
 (i) General Provisions Relating to Transfers and Exchanges. 

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall
authenticate Global Notes and Definitive Notes upon the Issuer’s order or at the Registrar’s request. 

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a
Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or
similar governmental charge payable upon exchange or transfer pursuant to Sections 2.02, 2.10, 3.08 and 9.05 hereof). 

(iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for
redemption in whole or in part, except for the unredeemed portion of any Note being redeemed in part. 
 (iv)
All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits hereof, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (v) Neither
the Issuer nor the Registrar shall be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business on a Business Day 15 days before the day of any selection of Notes for
redemption under Section 3.02 hereof and ending at the close of business on the day of selection or (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part. 
 (vi) Prior to due presentment for the registration of a transfer of any
Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other
purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 

(vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of

Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof. 

  
 -42- 

 (x) By its acceptance of any Definitive Note or interest in
any Global Note bearing the Canadian Private Placement Legend, each Holder of the Note represented thereby acknowledges the restrictions on transfer of such Note set forth in the Canadian Private Placement Legend affixed to such Note and agrees that
in connection with any sale, transfer or trade of such Note or its interest in such Note to a Person, or a Person resident of, or a Person acquiring such Note or an interest herein for the benefit of another Person resident in, any province or
territory of Canada, it will so sell, transfer or trade such Note or interest therein only in compliance with Canadian Securities Laws. 

(xi) The Trustee shall only be required to affix the Canadian Private Placement Legend to any Definitive Note
and any Global Note until (but not after) the day specified in the Canadian Private Placement Legend initially affixed to such Note on the date of its original issue, and shall affix such legend only upon the written instructions of the Issuer. 

(xii) Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the
Depositary. 
 SECTION 2.07 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to their satisfaction of
the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed by two Officers of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements for replacements
of Notes are met. If required by the Trustee or the Issuer, the Holder must supply an indemnity bond sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent or any authenticating agent from any loss
which any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a Note. 

Every replacement Note is a joint and several obligation of the Issuer. 

SECTION 2.08 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation and those described in this Section 2.08 as not outstanding. 
 If a Note is replaced
pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 

If the principal amount of any Note is considered paid under Section 4.01 hereof, it shall cease to be outstanding and
interest on it shall cease to accrue. 
 Subject to Section 2.09 hereof, a Note does not cease to be outstanding
because the Issuer, a Subsidiary of the Issuer or an Affiliate of the Issuer holds the Note. 
 SECTION 2.09 Treasury
Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred
in any direction, waiver or consent, Notes owned by the Issuer, any Subsidiary of the Issuer or any Affiliate of the Issuer shall be considered as though not outstanding, except that for purposes of determining whether the Trustee shall be protected
in relying on any such direction, waiver or consent, only Notes which a Responsible Officer knows to be so owned shall be so considered. Notwithstanding the foregoing, Notes that are to be acquired by the Issuer, any Subsidiary of the Issuer or an
Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by the Issuer, a Subsidiary of the Issuer or an Affiliate of the Issuer until legal title to such Notes passes to the Issuer, such
Subsidiary or such Affiliate, as the case may be. 

  
 -43- 

 SECTION 2.10 Temporary Notes. 

Until Definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer and the Trustee consider appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee, upon
receipt of the written order of the Issuer signed by two Officers of the Issuer, shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges
as Definitive Notes. 
 SECTION 2.11 Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of all canceled
Notes in its customary manner (subject to the record retention requirements of the Exchange Act), unless the Issuer directs canceled Notes to be returned to it. The Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that
have been delivered to the Trustee for cancellation. All canceled Notes held by the Trustee shall be disposed of and certification of their disposal delivered to the Issuer upon its request therefor, unless by a written order, signed by two Officers
of the Issuer, the Issuer shall direct that canceled Notes be returned to it. 
 SECTION 2.12 Defaulted
Interest. 
 If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders of the Notes on a subsequent special record date, which date shall be at the earliest practicable date but in
all events at least five Business Days prior to the payment date, in each case at the rate provided in the Notes. The Issuer shall, with the consent of the Trustee, fix or cause to be fixed each such special record date and payment date. At least 15
days before the special record date, the Issuer (or the Trustee, in the name of and at the expense of the Issuer) shall send to Holders of the Notes a notice that states the special record date, the related payment date and the amount of such
interest to be paid. 
 SECTION 2.13 Interest Disclosure. 

(a) For the purposes of the Interest Act (Canada) and disclosure thereunder, whenever any interest or any fee to be paid
under any Notes Document is to be calculated on the basis of a 360-day or 365-day year, the yearly rate of interest to which the rate used in such calculation is
equivalent is the rate so used multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by 360 or 365, as applicable. The rates of interest under the Notes Documents are nominal rates, and not
effective rates or yields. The principle of deemed reinvestment of interest does not apply to any interest calculation under the Notes Documents. 

(b) If any provision of the Notes Documents would oblige any Person to make any payment of interest or other amount payable to
any other Person in an amount or calculated at a rate which would be prohibited by applicable law or would result in a receipt by that Person of “interest” at a “criminal rate” (as such terms are construed under the Criminal
Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by such
applicable law or so result in a receipt by that Person of “interest” at a “criminal rate.” 
 SECTION 2.14
CUSIP Number. 
 The Issuer in issuing the Notes may use a “CUSIP” number and, if it
does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice 

  
 -44- 

 
may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other
identification numbers printed on the Notes and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee in writing of any change in the CUSIP number. 

ARTICLE 3 
 REDEMPTION 

SECTION 3.01 Notices to Trustee. 

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall
furnish to the Trustee, at least 5, but no more than 10, Business Days (unless a shorter period is acceptable to the Trustee) before the notice of redemption is delivered to Holders, an Officers’ Certificate of the Issuer setting forth
(i) the redemption date, (ii) the principal amount of Notes to be redeemed and (iii) the redemption price. If the Issuer is required to make the redemption pursuant to Section 3.08 hereof, it shall furnish the Trustee, at least
five but not more than ten Business Days before the applicable purchase date, an Officers’ Certificate of the Issuer setting forth (i) the purchase date, (ii) the principal amount of Notes offered to be purchased and (iii) the
purchase price. 
 SECTION 3.02 Selection of Notes To Be Redeemed. 

(a) If less than all of the Notes are to be redeemed at any time in accordance with Section 3.07(b) hereof, the selection
of Notes for redemption shall be made on a pro rata basis, except that Global Notes shall be selected, subject to the applicable rules of the Depositary; provided that no Notes with a principal amount of $2,000 or less shall be redeemed in
part. If less than all the Notes are to be redeemed at any time in accordance with Section 3.07(a), (c) and (d) hereof, then the Notes shall be selected by lot, except that Global Notes shall be selected subject to the applicable rules of
the Depository. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 15 nor more than 60 days prior to the redemption date from the outstanding Notes not
previously called for redemption. 
 (b) The Trustee shall promptly notify the Issuer in writing of the Notes selected for
redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of them selected shall be in amounts of $2,000 or whole multiples of $1,000; except that if all of the Notes of
a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions hereof that apply to Notes called for redemption
also apply to portions of Notes called for redemption. 
 SECTION 3.03 Notice of Redemption. 

Subject to the provisions of Section 3.08 hereof, at least 10 days but not more than 60 days before a redemption date, the
Issuer shall transmit a notice of redemption to each Holder (with a copy to the Trustee) whose Notes are to be redeemed to such Holder’s registered address. 

The notice shall identify the Notes to be redeemed and shall state 

(i) the redemption date; 

(ii) the redemption price; 

(iii) if any Note is being redeemed in part only, the portion of the principal amount of such Note to be
redeemed; 
 (iv) the name and address of the Paying Agent; 

  
 -45- 

 (v) that Notes called for redemption must be surrendered to
the Paying Agent to collect the redemption price; 
 (vi) that, unless the Issuer defaults in making such
redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 

(vii) the paragraph of the Notes and/or section hereof pursuant to which the Notes called for redemption are
being redeemed; and 
 (viii) that no representation is made as to the correctness or accuracy of the CUSIP
number, if any, listed in such notice or printed on the Notes. 
 At the Issuer’s written request, the Trustee shall
give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided that the Issuer shall have delivered to the Trustee, at least 10 days (unless a shorter period is acceptable to the Trustee) prior to the date
the Issuer wishes to have the notice given, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

SECTION 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become due and
payable on the redemption date at the redemption price. 
 SECTION 3.05 Deposit of Redemption Price. 

On or prior to 1:00 p.m. Eastern Time on any redemption date, the Issuer shall deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the
Issuer in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 

On and after the redemption date, if the Issuer does not default in the payment of the redemption price, interest shall cease
to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes. 

SECTION 3.06 [Reserved]. 

SECTION 3.07 Optional Redemption. 

Except as provided in paragraphs (a) and (b) below and Section 4.15 hereof, the Notes shall not be redeemable at the
Issuer’s option prior to November 1, 2022. Thereafter, the Notes shall be subject to redemption at the option of the Issuer, in whole or in part, upon not less than 10 days’ or more than 60 days’ notice, at the redemption prices
(expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon to the applicable redemption date (subject to the rights of Holders of record of the Notes on the relevant record date to receive
payments of interest on the related interest payment date), if redeemed during the 12-month period beginning on November 1 of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2022
	  	 	103.500	% 
	 2023
	  	 	101.750	% 

  
 -46- 

					
	 2024 and thereafter
	  	 	100.000	% 

  
 (a) Notwithstanding the
foregoing, at any time and from time to time prior to November 1, 2022, the Issuer may redeem up to 40% of the original aggregate principal amount of the Notes outstanding at a redemption price equal to 107.000% of the principal amount thereof
on the repurchase date, together with accrued and unpaid interest to such redemption date (subject to the rights of Holders of record of the Notes on the relevant record date to receive payments of interest on the related interest payment date),
with an amount equal to the net cash proceeds of one or more public or private sales of Qualified Capital Stock (each, an “Equity Offering”), other than proceeds from a sale to the Issuer or any of its Subsidiaries or any employee
benefit plan in which the Issuer or any of its Subsidiaries participates; provided that (i) at least 60% in aggregate principal amount of the Notes originally issued remains outstanding immediately after the occurrence of such redemption
(including additional Notes but excluding Notes held by the Issuer or any of its Restricted Subsidiaries) unless all such Notes are redeemed substantially concurrently and (ii) such redemption occurs no later than the 120th day following
such sale of Qualified Capital Stock. 
 (b) In addition, at any time and from time to time prior to November 1, 2022,
the Issuer may redeem all or any portion of the Notes outstanding at a redemption price equal to (i) 100% of the aggregate principal amount of the Notes to be redeemed, together with accrued and unpaid interest to such redemption date (subject
to the rights of Holders of record of the Notes on the relevant record date to receive payments of interest on the related interest payment date), plus (ii) the Make Whole Amount. 

(c) In connection with any redemption of Notes described in clauses (a), (b) and (c) above, such redemption may, at the
Issuer’s discretion, be subject to one or more conditions precedent, including any related Equity Offering, issuance of Indebtedness or other transaction. If such redemption or notice is subject to satisfaction of one or more conditions
precedent, such notice shall state that, in the Issuer’s discretion, such redemption may not occur and such notice may be rescinded, or the redemption date may be delayed or extended, in the event that any or all such conditions shall not have
been satisfied by the redemption date. 
 (d) Notwithstanding the foregoing, in connection with any tender offer for the
Notes, including a Change of Control Offer, if holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer or Change of Control Offer and the Issuer, or any
third party making such tender offer or Change of Control Offer in lieu of the Issuer, purchases all of the Notes validly tendered and not withdrawn by such holders, the Issuer or such third party will have the right upon not less than 10 nor more
than 60 days’ prior notice, given not more than 30 days following such purchase date, to redeem all Notes that remain outstanding following such purchase at a redemption price equal to the price offered to each other holder (excluding any early
tender or incentive fee) in such tender offer or Change of Control Offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the date of such redemption. 

(e) Tax Redemption. If (a) the Issuer or any Guarantor becomes or will become obligated to pay Additional Amounts
with respect to any Notes or any Guarantee (as described under Section 4.19) as a result of (1) any change in, or amendment to, the laws, treaties (including protocols), regulations or rulings of a Relevant Tax Jurisdiction, which change
or amendment is first publicly announced and becomes effective after the Issue Date (or, if the Relevant Tax Jurisdiction did not become a Relevant Tax Jurisdiction until a later date, after such later date) or (2) any change in the official
interpretation or application of the laws, treaties (including protocols), regulations or rulings of a Relevant Tax Jurisdiction (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published
administrative practice), which change is first publicly announced and becomes effective after the Issue Date (or, if the Relevant Tax Jurisdiction did not become a Relevant Tax Jurisdiction until a later date, after such later date), and
(b) such obligation cannot be avoided by the Issuer’s taking reasonable measures available to the Issuer or any Guarantor (provided that changing the jurisdiction of the Issuer or any Guarantor is not a reasonable measure for this
purpose), the Issuer may at its option, having given not less than 30 days’ notice to the holders of such Notes (which notice shall be irrevocable), redeem all, but not a portion of, the Notes at any time a price equal to their principal amount
plus interest accrued to, but excluding, the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), provided that no such notice of redemption shall
be given earlier than 60 days prior to the earliest date on which the Issuer or any Guarantor would be obliged to pay such Additional Amounts were a payment in respect of the Notes then due); and provided further that in the case of a Guarantor, no
redemption shall be permitted under

this Section 3.07(e) if the Issuer or any other Guarantor can make payments on the Notes without the obligation to pay Additional Amounts. Prior to the publication or, where relevant,
mailing of any notice of redemption pursuant to this paragraph, the Issuer shall deliver to the Trustee (i) a certificate of an officer of the Issuer stating that the requirements described in clauses (a) and (b) of this
Section 3.07(e) are satisfied, and (ii) an opinion of an independent counsel of recognized standing to the effect that the Issuer or any Guarantor has or will become obliged to pay such Additional Amounts as a result of a change or
amendment described in clause (a) of this Section 3.07(e). The Trustee shall accept, and will be entitled to rely on, such certificate and opinion of counsel as sufficient evidence of the existence and satisfaction of the conditions
described in clauses (a) and (b) of this Section 3.07(e), and upon such acceptance by the Trustee the Issuer will be entitled to give notice of redemption hereunder and such notice of redemption will be conclusive and binding on the
holders of the Notes. 
 SECTION 3.08 Excess Proceeds Offer. 

(a) In the event that, pursuant to Section 4.10, the Issuer shall be required to commence an Excess Proceeds Offer, it
shall follow the procedures specified below. 
 (b) The Excess Proceeds Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the
“Purchase Date”), the Issuer shall purchase the maximum principal amount of Notes and First Lien Obligations that may be purchased with such Excess Proceeds (which maximum principal amount of Notes and First
Lien Obligations shall be the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes tendered in response to the Excess Proceeds Offer. 

(c) To the extent the Issuer or a Restricted Subsidiary is required under the terms of any First Lien Obligations, the Issuer
shall make an offer to the holders of such First Lien Obligations on a pro rata basis with the holders of the Notes, with such proceeds. If the aggregate principal amount of Notes and other First Lien Obligations surrendered by holders
thereof exceeds the amount of such Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis by lot, and, in the case of Global Notes, in accordance with the procedures of the Depositary. To the extent that the
principal amount of Notes tendered pursuant to an Excess Proceeds Offer is less than the amount of such Excess Proceeds and such other First Lien Obligations, the Issuer may use any remaining Excess Proceeds in any manner not prohibited by this
Indenture. 
 (d) If the Purchase Date is on or after an interest record date and on or before the related interest payment
date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Excess
Proceeds Offer. 
 (e) Upon the commencement of any Excess Proceeds Offer, the Issuer shall send, by first class mail or
electronically, a notice to each of the Holders of the Notes, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Excess Proceeds Offer. The notice,
which shall govern the terms of the Excess Proceeds Offer, shall state: 
 (i) that the Excess Proceeds Offer
is being made pursuant to this Section 3.08 and the length of time the Excess Proceeds Offer shall remain open; 

(ii) the Offer Amount, the purchase price and the Purchase Date; 

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

(iv) that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the
Excess Proceeds Offer shall cease to accrue interest after the Purchase Date; 
 (v) that Holders electing to
have a Note purchased pursuant to any Excess Proceeds Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the 

  
 -48- 

 
reverse of the Note completed, to the Issuer, a Depositary, if appointed by the Issuer, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase
Date; 
 (vi) that Holders shall be entitled to withdraw their election if the Issuer, Depositary or Paying
Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and
a statement that such Holder is unconditionally withdrawing his election to have the Note purchased; and 

(vii) that, if the aggregate principal amount of Notes surrendered by Holders and other First Lien Obligations
tendered by the holders thereof exceeds the Offer Amount, the Trustee shall select the Notes to be purchased on a pro rata basis, by lot, and, in the case of Global Notes, in accordance with the procedures of the Depositary (with such
adjustments as may be deemed appropriate by the Issuer so that only Notes in minimum denominations of $2,000, or integral multiples of $1,000 in excess thereof, shall be purchased). 

(f) On or before the Purchase Date, the Issuer shall, to the extent lawful, accept for payment, on a pro rata basis to
the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Excess Proceeds Offer, or if less than the Offer Amount has been tendered, all Notes or portion thereof tendered, and deliver to the Trustee an
Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.08. The Issuer, Depositary or Paying Agent, as the case may be, shall promptly (but in
any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Note tendered by such Holder and accepted by the Issuer for purchase, and the Issuer shall promptly
issue a new Note, and the Trustee shall authenticate and mail or deliver such new Note, to such Holder equal in principal amount to any unpurchased portion of the Note surrendered. In addition, the Issuer shall take any and all other actions
required by the agreements governing any other First Lien Obligations. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Excess Proceeds Offer on
the Purchase Date. 
 (g) The Issuer shall comply with the requirements of Rule 14e-1
under the Exchange Act (or any successor rules) and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes pursuant to an Excess Proceeds Offer. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer’s compliance with such laws and regulations shall not in and of itself be deemed to have caused a breach of its
obligations under this Indenture. 
 (h) Other than as specifically provided in this Section 3.08 or Section 4.10,
any purchase pursuant to this Section 3.08 shall be made pursuant to the provisions of Sections 3.02 and 3.05 hereof.

(g) Delivery of such reports, information and documents pursuant to this Section 4.03 to the Trustee is for informational
purposes only and the Trustee’s receipt of such reports, information or documents shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the
Issuer’s compliance with any of their covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). Neither the Trustee nor the Notes Collateral Agent shall be obligated
to monitor or confirm, on a continuing basis or otherwise, the Issuer’s compliance with the covenants in this Indenture with respect to the furnishing or posting of such reports, information and documents

manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance hereof; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and

(7) payments or distributions by the Issuer or any of its Restricted Subsidiaries to dissenting stockholders

actually received by the Issuer from any such sale of Designated Preferred Stock (other than Disqualified Stock) issued after the Issue Date; 

(10) any Restricted Payment if after giving effect to such Restricted Payment, the Consolidated Leverage Ratio
of the Issuer on a pro forma basis is equal to or less than 3.75 to 1.00; 
 (11) to the extent constituting
Restricted Payments, payments to counterparties under Hedging Obligations or other hedge, swap or option agreements entered into in connection with the issuance of convertible debt or upon the exercise thereof; and

 (c)
Restricted Payments made pursuant to Section 4.07(a) and clause (1) of Section 4.07(b) and, to the extent made with the proceeds of the issuance of Qualified Capital Stock, Investments made pursuant to clause (j) of the
definition of “Permitted Investments,” shall be included as Restricted Payments in any computation made pursuant to clause (3) of Section 4.07(a). Restricted Payments made pursuant to clauses (2) through (10) and
(12) of Section 4.07(b) shall not be included as Restricted Payments in any computation made pursuant to clause (3) of Section 4.07(a). 

If the Issuer or any Restricted Subsidiary makes a Restricted Investment and the Person in which such Investment was made
subsequently becomes a Restricted Subsidiary, to the extent such Investment resulted in a reduction in the amounts calculated under clause (3) of Section 4.07(a) or under any other provision of this Section 4.07, (which was not
subsequently reversed), then such amount shall be increased by the amount of such reduction. 
 For purposes of determining
compliance with this Section 4.07, in the event that a Restricted Payment (or portion thereof) meets the criteria of more than one of the categories described in the clauses above, or is permitted pursuant to Section 4.07(a), the Issuer
shall be entitled to divide or classify (or later divide, classify or reclassify in 

  
 -55- 

 
whole or in part in its sole discretion) such Restricted Payment (or portion thereof) in any manner that complies with this Section 4.07. 

The amount of all Restricted Payments (other than cash) shall be fair market value on the date of such Restricted Payment of
the asset(s) or securities proposed to be paid, transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The fair market value of any cash Restricted Payment shall be its face
amount, and the fair market value of any non-cash Restricted Payment, property or assets other than cash shall be determined conclusively by the Issuer acting in good faith. 

If the Issuer or a Restricted Subsidiary makes a Restricted Payment which at the time of the making of such Restricted Payment
would in the good faith determination of the Issuer be permitted under the provisions of this Indenture, such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustments made in
good faith to the Issuer’s financial statements affecting Consolidated Net Income or Consolidated EBITDA of the Issuer for any period. 

SECTION 4.08 Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. 

The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or

regulation; 
 (iii) any instrument governing Acquired Debt and any other agreement or instrument of an
acquired Person or any of its Subsidiaries as in effect at the time of acquisition (except to the extent such Indebtedness or other agreement or instrument 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 or any of its Subsidiaries; 

(iv) by reason of customary nonassignment provisions in leases entered into in the ordinary course of business;

(vi) this Indenture, the Notes and the Collateral Documents or the Issuer’s other Indebtedness ranking
pari passu with the Notes; provided that except as set forth in clause (vii) below such restrictions are no more restrictive taken as a whole than those imposed by this Indenture, the Notes and the Collateral Documents; 

(vii) any Indebtedness; provided that the restrictions therein (i) are not materially more
restrictive than the agreements governing such Indebtedness as in effect on the Issue Date or (ii) will not affect

the Issuer’s ability to make principal or interest payments on the Notes (as determined by the Issuer in good faith); 

(viii) customary non-assignment provisions in contracts, leases, sub-leases and licenses entered into in the ordinary course of business; 

(ix) any agreement for the sale or other disposition of a Restricted Subsidiary or any of its assets in
compliance with the terms of this Indenture that restricts distributions by that Restricted Subsidiary pending such sale or other disposition;

Subsidiary (or sale of such Subsidiary’s Equity Interests) pending its sale; provided that during the entire period in which such encumbrance or restriction is effective, such sale (together with any other sales pending) would be
permitted under the terms of this Indenture; 
 (xiii) secured Indebtedness otherwise permitted to be
incurred by this Indenture that limits the right of the debtor to dispose of the assets securing such Indebtedness; 

(xiv) Purchase Money Indebtedness that imposes restrictions of the type described in clause (c) above on
the property so acquired; 
 (xv) any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (i) through (xiv) above; provided that such amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings are, in the Issuer’s good faith judgment, not materially more restrictive as a whole with respect to such encumbrances and restrictions than those prior to such amendment, modification,
restatement, renewal, increase, supplement, refunding, replacement or refinancing; 
 (xvi) Indebtedness or
other agreements, including, without limitation, agreements described in clause (x) of this paragraph, of any non-Guarantor Subsidiary which imposes restrictions solely on such non-Guarantor Subsidiary and its Subsidiaries; or

clause (10) or in clause (11), (14), (15) or (20) below (“Refinancing Indebtedness”); provided, however, that: 

(A) the principal amount of such Refinancing Indebtedness shall not exceed the principal amount and accrued
interest of the Indebtedness so exchanged, extended, refinanced, renewed, replaced, substituted or refunded and any premiums payable and reasonable fees, expenses, commissions and costs in connection therewith; 

(B) the Refinancing Indebtedness shall have a final maturity equal to or later than, and a Weighted Average

 (D) if the Indebtedness to be exchanged, refinanced, renewed,

(26) (a) Indebtedness of the Issuer or any Restricted Subsidiary to any Professional Services Affiliate

Restricted Subsidiary in respect of letters of credit, banker’s acceptances or other similar instruments or obligations issued for the benefit of, or relating to liabilities or obligations incurred on behalf of, a Professional Services
Affiliate, incurred in the ordinary course of business pursuant to or in connection with Management Services Agreement. 

(c) For purposes of determining compliance with this Section 4.09, (1) the outstanding principal amount of any item
of Indebtedness shall be counted only once, and any obligation arising under any guarantee, Lien, letter of credit or similar instrument supporting such Indebtedness incurred in compliance with this Section 4.09 shall be disregarded, and
(2) if an item of Indebtedness meets the criteria of more than one of the categories described in clauses (b)(1) through (26) above or is permitted to be incurred pursuant to Section 4.09(a) and also meets the criteria of one or
more of the categories described in clauses (1) through (26) of Section 4.09(b), the Issuer shall, in its sole discretion, classify such item of Indebtedness in any manner that complies with this Section 4.09 and may from time to
time reclassify such item of Indebtedness in any manner in which such item could be incurred at the time of such reclassification; provided that Indebtedness outstanding under the Credit Agreement on the Issue Date (and any Indebtedness
secured by a Lien that refinances such Indebtedness) shall be deemed to be outstanding under clause (b)(2) above and may not be reclassified. 

(d) Accrual of interest or dividends on Preferred Equity Interests, the accretion of original issue discount and the payment of
interest or dividends on Preferred Equity Interests in the form of additional Indebtedness or Preferred Equity Interests of the same class shall not be deemed to be an incurrence of Indebtedness for purposes of determining compliance with this
Section 4.09. Any increase in the amount of Indebtedness solely by reason of currency fluctuations shall not be deemed to be an incurrence of Indebtedness for purposes of determining compliance with this Section 4.09. A change in IFRS that
results in an obligation existing at the time of such change, not previously classified as Indebtedness, becoming Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of determining compliance with this
Section 4.09. 

  
 -61- 

 (e) The amount of indebtedness outstanding as of any date shall be
(1) the accreted value thereof, in the case of any Indebtedness issued with original issue discount, (2) the principal amount thereof, in the case of any other Indebtedness, (3) in the case of the guarantee by the specified Person of
any Indebtedness of any other Person, the maximum liability to which the specified Person may be subject upon the occurrence of the contingency giving rise to the obligation and (4) in the case of Indebtedness of others guaranteed by means of a
Lien on any asset of the specified Person, the lesser of (A) the Fair Market Value of such asset on the date on which Indebtedness is required to be determined pursuant to this Indenture and (B) the amount of the Indebtedness so secured.

 (f) For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated by the Issuer based on the relevant currency
exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other
Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect
on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal
amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Issuer may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as
a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, (1) if incurred in a different currency from the Indebtedness being refinanced, shall be calculated
by the Issuer based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing and (2) shall be deemed to be outstanding only when the
proceeds thereof are not applied to effect such refinancing (and to pay any fees, expenses, commissions and costs in connection therewith) substantially concurrently. 

(g) Notwithstanding anything to the contrary in this Section 4.09, in the case of any Indebtedness incurred to refinance
Indebtedness initially incurred in reliance on one or more of clauses (1) through (26) of Section 4.07(b) measured by reference to a percentage of Consolidated EBITDA at the time of incurrence, if such refinancing would cause the
percentage of Consolidated EBITDA restriction to be exceeded if calculated based on the percentage of Consolidated EBITDA on the date of such refinancing, such percentage of Consolidated EBITDA restriction shall not be deemed to be exceeded so long
as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced, plus accrued and unpaid interest, dividends, premiums (including tender premiums), defeasance costs, underwriting
discounts, fees, costs and expenses (including original issue discount, upfront fees or similar fees) in connection with such refinancing. 

(h) For the avoidance of doubt, unsecured Indebtedness shall not be treated as subordinated or junior to Secured Indebtedness
merely because it is unsecured. 
 SECTION 4.10 Limitation on Asset Sales. 

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale
unless: 
 (1) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset Sale
at least equal to the Fair Market Value (determined as of the time of contractually agreeing to such Asset Sale) of the assets included in such Asset Sale); and 

(2) other than with respect to Permitted Asset Swaps, at least 75% of the total consideration in such Asset
Sale consists of cash or Cash Equivalents or Marketable Securities. 
 For purposes of clause (2), the following shall
be deemed to be cash: 
 (a) the amount (without duplication) of any Indebtedness (other than Subordinated
Indebtedness) of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee in such Asset 

  
 -62- 

 
Sale and with respect to which the Issuer or such Restricted Subsidiary, as the case may be, is unconditionally released by the holder of such Indebtedness, 

(b) the amount of any obligations or securities received from such transferee that are within 180 days
converted by the Issuer or such Restricted Subsidiary to cash (to the extent of the cash actually so received), 

(c) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such
Asset Sale, to the extent that the Issuer and each other Restricted Subsidiary are released from any Guarantee of payment of such Indebtedness in connection with such Asset Sale; and 

(d) any Designated Non-cash Consideration received by the Issuer or
such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (c), not to exceed the
greater of $7.5 million and 10.0% of Consolidated EBITDA for the most recently ended Measurement Period (calculated on a pro forma basis), with the Fair Market Value of each item of Designated
Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value. 

(b) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall apply
all or any of the Net Proceeds therefrom to: 
 (1) at the Issuer’s election, either (x) repay
First Lien Obligations (and in the case of any such repayment under any revolving credit facility, effect a permanent reduction in the availability under such revolving credit facility) or (y) repay, redeem or purchase the Notes;
provided that if the Issuer or such Restricted Subsidiary repays First Lien Obligations (other than the Notes) pursuant to clause (b)(i)(x) of this Section 4.10, the Issuer shall apply a pro rata amount to (i) equally and ratably
reduce the Notes Obligations in accordance with the procedures set forth under Section 3.07 and/or (ii) make an Excess Proceeds Offer; or 

(2) (A) invest all or any part of the Net Proceeds thereof in capital expenditures or the purchase of assets to
be used by the Issuer or any Restricted Subsidiary in a Permitted Business, (B) acquire Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged primarily in a Permitted Business that shall become a Restricted
Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B). 
 (c)
Notwithstanding any other provisions of this Section 4.10, (i) to the extent that any of or all the Net Proceeds of any Asset Sale received or deemed to be received by a Foreign Subsidiary (a “Foreign Disposition”) is
(x) prohibited or delayed by applicable local law or (y) restricted by applicable organizational documents in each case, from being repatriated to Canada if the Issuer is organized under the laws of Canada or a political subdivision
thereof or the United States, if the Issuer is organized under the laws of the United States or any State thereof or the District of Columbia, an amount equal to the portion of such Net Proceeds so affected will not be required to be applied in
compliance with this Section 4.10 so long, but only so long, as the applicable local law or organizational documents will not permit repatriation to the United States or Canada, as applicable, (the Issuer hereby agreeing to use reasonable
efforts (as determined in the Issuer’s reasonable business judgment) to otherwise cause the applicable Foreign Subsidiary to within one year following the date on which the respective payment would otherwise have been required, promptly take
all actions reasonably required by the applicable local law or applicable organizational impediments to permit such repatriation), and if within one year following the date on which the respective payment would otherwise have been required, such
repatriation of any of such affected Net Proceeds is permitted under the applicable local law or applicable organizational impediment, an amount equal to such Net Proceeds will be promptly (and in any event not later than five Business Days after
such repatriation could be made) applied (net of additional Taxes payable or reserved against as a result thereof) (whether or not repatriation actually occurs) in compliance with this Section 4.10 and (ii) to the extent that the Issuer
has determined in good faith that repatriation of any of or all the Net Proceeds of any Foreign Disposition would have an material adverse Tax consequence (which for the avoidance of doubt, includes, but is not limited to, any prepayment out of such
Net Proceeds whereby doing so the Issuer, any of its Subsidiaries or any of their respective affiliates and/or equity owners would incur a Tax liability, including a Tax dividend, deemed dividend pursuant to Code Section 956 or a withholding
Tax), an 

  
 -63- 

 
amount equal to the Net Proceeds so affected will not be required to be applied in compliance with this Section 4.10. The non-application of any
prepayment amounts as a consequence of the foregoing provisions will not, for the avoidance of doubt, constitute a Default or an Event of Default. 

(d) Any Net Proceeds from any Asset Sale that are not applied or invested (or committed pursuant to a written agreement to be
applied) as provided in the preceding paragraph within 365 days after the receipt thereof and, in the case of any amount committed to a reinvestment, which are not actually so applied within 180 days following such 365 day period
shall constitute “Excess Proceeds” and shall be applied pursuant to Section 4.10(d) hereof. Pending the final application of any such Net Proceeds, the Issuer or such Restricted Subsidiary may temporarily reduce revolving
indebtedness under a Credit Facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture. 

(e) When the cumulative amount of Excess Proceeds that have not been applied in accordance with this Section 4.10 exceeds
$20.0 million, the Issuer shall make an offer to all Holders of the Notes (an “Excess Proceeds Offer”) to purchase the maximum principal amount of Notes that may be purchased out of such Excess Proceeds at an offer price in
cash in an amount equal to 100% of the principal amount thereof, together with accrued and unpaid interest to the date fixed for the closing of such offer in accordance with the procedures set forth in Section 3.08 hereof. Upon completion of an
Excess Proceeds Offer, the amount of Excess Proceeds shall be reset at zero. 
 SECTION 4.11 Limitation on Transactions with
Affiliates. 
 The Issuer shall not and shall not permit any Restricted Subsidiary to, directly or
indirectly, sell, lease, transfer or otherwise dispose of any of the Issuer’s or any Restricted Subsidiary’s properties or assets to, or purchase any property or assets from, or enter into any contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate (including any Unrestricted Subsidiary and Minority Investment) in any one or a series of transactions involving aggregate payments in excess of $5.0 million (or in the case of a
Minority Investment, in excess of $2.5 million) (each of the foregoing, an “Affiliate Transaction”), unless: 

(a) the terms of such Affiliate Transaction taken as a whole are not materially less favorable to the Issuer or such Restricted
Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction or the execution of the agreement providing for such transaction in arm’s length dealings with a Person who is not
such an Affiliate; and 
 (b) in the event such Affiliate Transaction involves an aggregate value in excess of the greater of
$7.5 million and 10% of Consolidated EBITDA for the most recently ended measurement period calculated on a pro forma basis), the terms of such transaction have been approved by a majority of the disinterested members of the Board of
Directors of the Issuer; 
 Any Affiliate Transaction shall be deemed to have satisfied the requirements set forth in clause (b) above
if such Affiliate Transaction is approved by a majority of the disinterested directors of the Issuer, if any. 
 provided,
however, that the following shall, in each case, not be deemed Affiliate Transactions: 
 (i) the
entry into employment agreements and the adoption of compensation or benefit plans for the benefit of, or the payment of compensation to, directors and management of the Issuer and its Subsidiaries (including, without limitation, salaries, fees,
bonuses, equity and incentive arrangements and payments); 
 (ii) indemnification or similar arrangements for
officers, directors, employees or agents of the Issuer or any of the Restricted Subsidiaries pursuant to charter, bylaw, statutory or contractual provisions; 

(iii) transactions between or among the Issuer and the Restricted Subsidiaries; 

  
 -64- 

 (iv) Restricted Payments not prohibited by Section 4.07
and Permitted Investments; 
 (v) any transactions between the Issuer or any of the Restricted Subsidiaries

other hand; 
 (vi) the payment of compensation, fees, costs and expenses to, and indemnities (including
under insurance policies) and reimbursements, employment and severance arrangements, and employee benefit and pension expenses provided on behalf of, or for the benefit of, future, current or former employees, directors, officers, managers,
contractors, consultants, distributors or advisors of the Issuer or any Restricted Subsidiary (whether directly or indirectly); 

(vii) any agreements or arrangements in effect on the Issue Date and described in the Offering Memorandum and
any modifications, extensions or renewals thereof that are not disadvantageous to the holders of Notes in the Issuer’s reasonable determination in any material respect; 

(viii) so long as they comply with clause (a) above, transactions with customers, clients, lessors,
landlords, suppliers, contractors or purchasers or sellers of goods or services that are Affiliates, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture; 

(ix) [reserved]; 

(x) transactions with Persons who are Affiliates of the Issuer solely as a result of the Issuer’s or a
Restricted Subsidiary’s Investment in such Person; 
 (xi) sales of Equity Interests to Affiliates of
the Issuer or its Restricted Subsidiaries not otherwise prohibited by this Indenture and the granting of registration and other customary rights in connection therewith; 

(xii) transactions with an Affiliate where the only consideration paid is Equity Interests of the Issuer other
than Disqualified Stock; 
 (xiii) transactions in which the Issuer or any of its Restricted Subsidiaries, as
the case may be, deliver to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view or meets the requirements of this covenant; 

(xiv) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of
business; 
 (xv) transactions between the Issuer or any of its Restricted Subsidiaries and any Person, a
director of which is also a director of the Issuer; provided, however, that such director abstains from voting as a director on any matter involving such other Person; 

(xvi) any transition services arrangement, supply arrangement or similar arrangement entered into in connection
with or in contemplation of the disposition of assets or Capital Stock in any Restricted Subsidiary permitted under Section 4.10 or entered into with any Business Successor, in each case, that the Issuer determines in good faith is either fair
to the Issuer or otherwise on customary terms for such type of arrangements in connection with similar transactions; 

(xvii) transactions entered into by an Unrestricted Subsidiary with an Affiliate prior to the day such
Unrestricted Subsidiary is redesignated as a Restricted Subsidiary (and not entered into in contemplation of such redesignation) as described in the definition of “Unrestricted Subsidiaries” and pledges of Capital Stock of Unrestricted
Subsidiaries; 

  
 -65- 

 (xviii) (i) any lease entered into between the Issuer
or any Restricted Subsidiary, as lessee, and any Affiliate of the Issuer, as lessor and (ii) any operational services arrangement entered into between the Issuer or any Restricted Subsidiary and any Affiliate of the Issuer, in each case, which

 SECTION 4.12 Limitation on Liens. 

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur or assume
any Lien (each, an “Initial Lien”) on any asset now owned or hereafter acquired, or on any income or profits therefrom or assign or convey any right to receive income therefrom, other than (i) Permitted Liens and (ii) with
respect to Liens on assets not constituting Collateral, any such Lien securing Indebtedness if the Notes are secured equally and ratably thereby (or, if such Indebtedness secured by Liens on assets not constituting Collateral is subordinated to the
Notes, the Notes are secured on a priority basis with respect to such Indebtedness). 
 (b) Any Lien created for the benefit
of the Holders pursuant to clause (ii) of Section 4.12(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 

(c) With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the incurrence
of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with
any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion of original issue discount or liquidation preference
and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness. 

SECTION 4.13 Additional Subsidiary Guarantees. 

If any of the Issuer’s Restricted Subsidiaries (including, for the avoidance of doubt, Professional Services Affiliates)
that is not a Guarantor guarantees or becomes otherwise obligated under a Credit Facility incurred under Section 4.09(b)(2) or any Capital Markets Indebtedness in an aggregate principal amount greater than $30.0 million incurred pursuant
to Section 4.09, then in each case such Restricted Subsidiary shall (i) execute and deliver to the Trustee and Collateral Agent a supplemental indenture in form reasonably satisfactory to the Trustee and the Collateral Agent pursuant to
which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and this Indenture on the terms set forth in this Indenture, (ii) execute and deliver to the Trustee and Collateral Agent
joinders or supplements, as applicable, to the Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement), together with any other filings and agreements (subject to customary
extension periods) required by the Collateral Documents to create or perfect the security interests of the Collateral Agent for its benefit and for the benefit of the Trustee and the holders of the Notes in the Collateral of such Restricted
Subsidiary and (iii) deliver to the Trustee and the Collateral Agent an Officers’ Certificate and an Opinion of Counsel that such supplemental indenture and joinders or supplements to the Collateral Documents and First Lien Intercreditor
Agreement (and, if applicable, any Junior Lien Intercreditor Agreement) have been duly authorized, executed and delivered by such Restricted Subsidiary and constitute legal, valid, binding and enforceable obligations of such Restricted Subsidiary.
Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture, the Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement). 

SECTION 4.14 Organizational Existence. 

Subject to Article 5 hereof and the proviso to this Section 4.14, the Issuer shall do or cause to be done all things
necessary to preserve and keep in full force and effect (i) its existence as a corporation and, subject to Section 4.10 hereof, the corporate, limited liability company, partnership or other existence of any Significant Subsidiary, in

  
 -66- 

 
accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any Significant Subsidiary and (ii) subject to Section 4.10
hereof, the rights (charter and statutory), licenses and franchises of the Issuer and its Significant Subsidiaries; provided, however, that the Issuer shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any Significant Subsidiary if the Board of Directors of the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 
 SECTION 4.15
Change of Control. 
 Upon the occurrence of a Change of Control, the Issuer shall make an offer
(a “Change of Control Offer”) to each Holder of Notes to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount
thereof, together with accrued and unpaid interest thereon to the date of repurchase (subject to the rights of Holders of record of the Notes on the relevant record date to receive payments of interest on the related interest payment date) (in
either case, the “Change of Control Payment”). Within 30 days following any Change of Control, the Issuer shall send or otherwise deliver a notice to each Holder electronically in accordance with the procedures of the depository or
by first-class mail with a copy to the Trustee stating: 
 (1) that the Change of Control Offer is being made
pursuant to this Section 4.15; 
 (2) the purchase price and the purchase date, which shall be no
earlier than 30 days and not later than 60 days after the date such notice is sent (the “Change of Control Payment Date”); 

(3) that any Notes not tendered shall continue to accrue interest in accordance with the terms of this
Indenture; 
 (4) that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes
accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date; 

(5) that Holders shall be entitled to withdraw their election if the paying agent receives, not later than the
close of business on the second Business Day preceding the Change of Control Payment Date, a notice sent electronically in accordance with the procedures of the depository or by first-class mail setting forth the name of the Holder, the principal
amount of Notes delivered for purchase, and a statement that such Holder is unconditionally withdrawing its election to have such Notes purchased; 

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

(7) any other information material to such Holder’s decision to tender Notes. 

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and
any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes required in the event of a Change of Control. The Issuer shall not be required to make a
Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to Change of Control Offer made
by the Issuer. The Issuer’s obligations in respect of a Change of Control Offer can be modified with the consent of Holders of a majority of the aggregate principal amount of Notes then outstanding at any time prior to the occurrence of a
Change of Control. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at
the time of making of the Change of Control Offer.

 SECTION 4.16 Suspension of Covenants. 

(a) During any period of time after the Issue Date that (i) the Notes are rated Investment Grade by both Rating Agencies
and (ii) no Default or Event of Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension
Event”), the Issuer and its Restricted Subsidiaries shall not be subject to the following Sections of this Indenture (the “Suspended Covenants”): 

(1) Section 4.07; 

(2) Section 4.09; 

(3) Section 4.10; 

(4) clause (d) of the first paragraph of Section 5.01; 

(5) Section 4.11; 

(6) Section 4.08; and 

(7) Section 4.13. 

(b) At such time as Sections 4.07, 4.08, 4.09, 4.10, 4.11 and clause (d) of the first paragraph of Section 5.01 are
suspended (a “Suspension Period”), the Issuer shall no longer be permitted to designate any Restricted Subsidiary as an Unrestricted Subsidiary. 

(c) In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of
time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade rating or downgrade the rating assigned to the Notes below Investment Grade,
then the Issuer and its Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events. 

(d) On each Reversion Date, all Indebtedness incurred during the Suspension Period prior to such Reversion Date shall be deemed
to be Existing Indebtedness. For purposes of calculating the amount available to be made as Restricted Payments under clause (3) of Section 4.07(a), calculations under such section shall be made as though such section had been in effect
during the entire period of time after the Issue Date (including the Suspension Period). Restricted Payments made during the Suspension Period not otherwise permitted pursuant to any of clauses (2) through (12) under Section 4.07(b) shall
reduce the amount available to be made as Restricted Payments under clause (3) of such Section 4.07(a); provided that the amount available to be made as Restricted Payments on the Reversion Date shall not be reduced to below zero
solely as a result of such Restricted Payments. For purposes of Section 4.10(d), on the Reversion Date, the unutilized amount of Net Proceeds shall be reset to zero. Notwithstanding the foregoing, neither (a) the continued existence, after
the Reversion Date, of facts and circumstances or obligations that were incurred or otherwise came into existence during a Suspension Period nor (b) the performance of any such obligations, shall constitute a breach of any covenant set forth
herein or cause a Default or Event of Default thereunder; provided that (1) the Issuer and its Restricted Subsidiaries did not incur or otherwise cause such facts and circumstances or obligations to exist in anticipation of a withdrawal
or downgrade by the applicable Rating Agency below an Investment Grade rating and (2) the Issuer reasonably believed that such incurrence or actions would not result in such withdrawal or downgrade. On each Reversion Date, the Issuer shall be
required to comply with the provisions under Section 4.13 as if such provisions were in effect at all times during the Suspension Period. 

The Issuer shall provide an Officers’ Certificate to the Trustee indicating the occurrence of any Covenant Suspension
Event, Suspension Period or Reversion Date. The Trustee shall have no obligation to monitor the ratings of the Notes, independently determine or verify if such events have occurred or notify the holders of Notes of any Covenant Suspension Event,
Suspension Period or Reversion Date. The Trustee may provide a copy of such Officers’ Certificate to any Holder of Notes upon request. 

  
 -68- 

 SECTION 4.17 After-acquired Collateral. 

From and after the Issue Date, if the Issuer or any Guarantor creates any additional security interest upon any Property that
would constitute Collateral to secure any First Lien Obligations, the Issuer and each of the Guarantors shall grant a first-priority perfected security interest (subject to Permitted Liens) upon any such Collateral, as security for the Notes
Obligations, subject to the limitations and exceptions set forth in the Collateral Documents. 
 SECTION 4.18
Further Assurances. 
 As set forth in the Collateral Documents and this Indenture,
the Issuer and the Guarantors shall, at their expense, duly execute and deliver, or cause to be duly executed and delivered, such further agreements, documents, instruments, financing and continuation statements (or equivalent statements) and
amendments thereto and do or cause to be done such further acts as may be necessary or proper or reasonably requested by the Collateral Agent to evidence, perfect, maintain and enforce the security interests and the priority thereof in the
Collateral in favor of the Collateral Agent for the benefit of the Notes Secured Parties, and to otherwise effectuate the provisions or purposes of this Indenture and the Collateral Documents. 

SECTION 4.19 Additional Amounts. 

All payments in respect of the Notes or any Guarantee by or on behalf of the Issuer, any Guarantor, or any successor thereto
(each, a “Payor”) shall be made free and clear of, and without withholding or deduction for, or on account of, any present or future taxes, levies, duties, imposts, assessments or other governmental charges, including any interest,
additions to tax and penalties related thereto (collectively, “Taxes”), unless such withholding or deduction is required by applicable law. If any Payor, or any other applicable withholding agent, is required to withhold or deduct
any amount in respect of any payment made in respect of the Notes or any Guarantee with respect to any Tax imposed by or on behalf of any jurisdiction in which any Payor is, at any time, organized, resident or doing business for tax purposes, or any
jurisdiction from or through which any Payor or any paying agent (on behalf of any Payor) makes any payments on the Notes or any Guarantee, or, in each case, any governmental authority or political subdivision thereof or therein having the power to
tax (each, a “Relevant Tax Jurisdiction”), the Payor will, subject to the exceptions and limitations set forth below, pay such additional amounts (“Additional Amounts”) as are necessary so that the net payment
received by a beneficial owner of the Notes (including any Additional Amounts), after withholding or deduction for any Taxes of any Relevant Tax Jurisdiction (including in respect of any Additional Amounts) will equal the amount such beneficial
owner would have received in respect of such payment had no such withholding or deduction been required. A Payor’s obligation to pay Additional Amounts shall not apply: 

(a) to any Taxes that are imposed by reason of the holder (or the beneficial owner for whose benefit such holder holds such
Note), or a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership or corporation, or a person holding a power over an estate or trust administered by a fiduciary holder, being considered
as: 
  

	 	i.	 being or having been engaged in a trade or business in the Relevant Tax Jurisdiction or having or having had
a permanent establishment in the Relevant Tax Jurisdiction; or 

  

	 	ii.	 having any other current or former connection with the Relevant Tax Jurisdiction (other than a connection
arising solely as a result of the acquisition, ownership or disposition of the Notes or a beneficial interest therein, the receipt of any payment in respect of a Note or any Guarantee or the enforcement of any rights hereunder or thereunder),
including being or having been a citizen or resident of the Relevant Tax Jurisdiction; 

 (b) to any Taxes
that are imposed or withheld because the holder or beneficial owner failed to accurately comply with a request from a Payor to meet certification, identification or information or other reporting requirements concerning the nationality, residence or
identity of the holder or beneficial owner of the Notes or otherwise establish any available exemption from or reduction in the rate of deduction or withholding of, such Taxes (if such holder or beneficial owner is legally eligible to satisfy such
requirements, exemptions or reductions), in each 

  
 -69- 

 
case, if compliance with such action is required as a precondition to exemption from, or reduction in, such Tax by a Relevant Tax Jurisdiction; 

(c) to any Taxes that are imposed other than by withholding or deduction by a Payor or other applicable withholding agent in
respect of a payment with respect to the Notes or any Guarantee; 
 (d) to any estate, inheritance, gift, sales, transfer,
wealth or similar Taxes; 
 (e) to any Taxes that are imposed as a result of the presentation of a Note for payment (where
presentation is required) more than 30 days after the relevant amount is first made available for payment to the holder (except to the extent that the holder would have been entitled to Additional Amounts had the Note been presented on the last day
of such 30-day period); 
 (f) to any Canadian withholding Taxes that are imposed on
payment on the Notes or Guarantees under the Income Tax Act (Canada) as a result of (i) the holder or beneficial owner not dealing at arm’s length (for the purposes of the Income Tax Act (Canada)) with the Issuer at the time such payment
is made, or (ii) the holder or beneficial owner being a “specified non-resident shareholder” (as defined in subsection 18(5) of the Income Tax Act (Canada)) of the Issuer at the time of payment
or not dealing at arm’s length (for the purposes of the Income Tax Act (Canada)) with a “specified shareholder” (as defined in subsection 18(5) of the Income Tax Act (Canada)) of the Issuer at the time of payment, as applicable; 

(g) to any Tax imposed pursuant to current Sections 1471 through 1474 of the Code (or any amended or successor version that is
substantively comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to current Section 1471(b) of the Code (or any amended or
successor version described above), or any intergovernmental agreements, treaties, conventions or similar agreements (and any related laws, regulations or administrative guidance) implementing the foregoing; 

(h) to any Taxes that are imposed on or with respect to any payment by or on behalf of the Issuer or any Guarantor to the
holder if such holder is a fiduciary, partnership, limited liability company or person other than the sole beneficial owner of such payment to the extent that, had the sole beneficial owner of such Note been the holder and had such Taxes been
imposed on the sole beneficial owner, no Additional Amounts in respect of such Taxes would have been payable as a result of clauses (a)-(g) or (i) of this Section 4.19; or 

(i) to any combination of the above items (the foregoing Taxes described in clauses (a)-(i), “Excluded
Taxes”). 
 For purposes of this Section 4.19, including clause (c) above, any Tax imposed pursuant to Regulation 803 of
the Income Tax Act (Canada) shall be treated as a Tax withheld by an applicable withholding agent even though such tax is payable directly by the holder or beneficial owner. 

At least 30 calendar days prior to each date on which any payment under or with respect to the Notes or any Guarantee is due and payable, if a
Payor will be obligated to pay Additional Amounts with respect to such payment (unless such obligation to pay Additional Amounts arises after the 35th day prior to the date on which such payment is due and payable, in which case it will be promptly
thereafter), the Payor will deliver to the Trustee a certificate of an officer of the Issuer stating that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Trustee
(or the applicable paying agent) to pay such Additional Amounts to holders on the payment date. 
 The applicable Payor, if it is the
applicable withholding agent, will make any required withholding or deduction and remit the full amount deducted or withheld to the Relevant Tax Jurisdiction in accordance with applicable law. The Issuer will provide the Trustees (and, upon request,
any holders or beneficial owners of the Notes) with official receipts or other documentation evidencing the payment of the Taxes with respect to which Additional Amounts are paid. 

  
 -70- 

 The Issuer and the Guarantors will pay and indemnify each holder of Notes for any present or
future stamp, court, issue, registration or documentary Taxes or any other excise, property or similar Taxes that are levied by any Relevant Tax Jurisdiction from the execution, delivery, enforcement or registration of the Notes (other than in
respect of a transfer of a Note, to someone other than the Issuer or its Affiliates, that occurs after the sale of such Note to an investor pursuant to the offering of the Notes), the Guarantees, this Indenture or any other document or instrument in
relation thereof, or the receipt of any payments with respect to the Notes or any Guarantee (limited, solely in the case of Taxes attributable to the receipt of any payments with respect thereto, to any such Taxes levied by a Relevant Tax
Jurisdiction that are not excluded under clauses (a), (b) and (d) through (h) or any combination thereof). Whenever in this Indenture there is mentioned in any context: the payment of principal, redemption prices or purchase prices in
connection with a redemption or purchase of Notes, interest, or any other amount payable with respect to any of the Notes or any Guarantee, such reference shall be deemed to include payment of Additional Amounts as described under this
Section 4.19 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. 
 The
obligations described under this Section 4.19 will survive any termination, defeasance or discharge of this Indenture, and any transfer by a holder or beneficial owner of its Notes and will apply mutatis mutandis to any successor
Person, to any Payor and to any jurisdiction in which such successor is organized or is otherwise resident or doing business for tax purposes or any jurisdiction from or through which payment is made by such successor or its respective agents. 

SECTION 4.20 Post-Closing Covenant. 

No later than thirty (30) days after the Issue Date (or such later date as the Credit Agreement Collateral Agent, in its reasonable
discretion, shall agree to under a corresponding provision of the Credit Agreement), the Issuer shall deliver, or cause to be delivered, to the Notes Collateral Agent endorsements to each of the Issuer’s property and liability insurance
policies naming the Notes Collateral Agent as loss payee and additional insured in form and substance reasonably acceptable to the Credit Agreement Collateral Agent under a corresponding provision of the Credit Agreement.

 SUCCESSORS 

SECTION 5.01 Merger, Consolidation or Sale of Assets. 

The Issuer shall not consolidate, amalgamate, participate in an arrangement with or merge with or into (whether or not the
Issuer is the surviving entity), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, another Person unless: 

(a) the Issuer is the surviving Person or the Person formed by or surviving any such consolidation, amalgamation, arrangement
or merger (if other than the Issuer ) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, limited partnership or limited liability company organized or existing under the laws of
the United States or any state thereof or Canada or any political subdivision thereof; provided, however, that if the surviving Person is a limited liability company or limited partnership, such entity shall also form a co-issuer that is a corporation; 
 (b) the Person formed by or surviving any such
consolidation, amalgamation, arrangement or merger (if other than the Issuer) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the Issuer’s obligations under the
Notes, this Indenture, the Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement) pursuant to a supplemental indenture and joinders or supplements, as applicable, to the
Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement), in each case, in form reasonably acceptable to the Trustee and Collateral Agent; 

(c) immediately after such transaction, no Event of Default exists; and 

  
 -71- 

 (d) the Issuer or the Person formed by or surviving any such consolidation,
amalgamation, arrangement or merger (if other than the Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made (i) will have a Consolidated Fixed Charge Coverage Ratio immediately after
the transaction (but prior to any purchase accounting adjustments or accrual of deferred tax liabilities resulting from the transaction) not less than the Issuer’s Consolidated Fixed Charge Coverage Ratio immediately preceding the transaction

any Restricted Subsidiary may consolidate, amalgamate with, participate in an arrangement with or merge into or transfer all or part of its properties and assets to the Issuer or another Restricted Subsidiary. 

Notwithstanding the foregoing clauses (c) and (d), this Article 5 shall not apply to a merger or amalgamation of the
Issuer with a Restricted Subsidiary solely for the purpose of reorganizing the Issuer in another jurisdiction of the United States or any State thereof or the District of Columbia or Canada or any political subdivision thereof so long as the amount
of Indebtedness of the Issuer and the Restricted Subsidiary is not increased thereby. 
 SECTION 5.02 Successor Corporation
Substituted. 
 Upon any consolidation, amalgamation, arrangement or merger, or any sale, lease,
conveyance or other disposition of all or substantially all of the assets of the Issuer in accordance with Section 5.01 hereof, the successor Person formed by such consolidation, merger, amalgamation or arrangement into or with which the Issuer
is consolidated, amalgamated, arranged or merged, to which such sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, amalgamation, arrangement, merger,
sale, lease, conveyance or other disposition, the provisions hereof referring to the Issuer shall refer instead to the successor corporation and not to the Issuer), and may exercise every right and power of, the Issuer under this Indenture with the
same effect as if such successor Person has been named as the Issuer herein. When a successor Person assumes all the obligations of the Issuer under the Notes and this Indenture pursuant to this Article 5, the applicable predecessor shall be
released from the obligations so assumed. 
 ARTICLE 6

by a failure to pay the principal of such Indebtedness at the final stated maturity thereof within the grace period provided in such Indebtedness (a “Payment Default”), and the principal amount of any such Indebtedness (including
the principal amount of commitments in respect of such Indebtedness), together with the principal amount of any other such Indebtedness (including the principal amount of commitments in respect of such Indebtedness) under which there has been a
Payment Default, aggregates $25.0 million or more; 
 (f) 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 (or commitments in respect of Indebtedness for borrowed money) by the Issuer and any of the Restricted Subsidiaries (or the payment of which
is guaranteed by the Issuer or any of the Restricted Subsidiaries), which default results in the acceleration of such Indebtedness (or termination of related commitments) prior to its express maturity not rescinded or cured within 30 days after
such acceleration (or termination of related commitments), and the principal amount of any such Indebtedness (including the principal amount of commitments in respect of such Indebtedness), together with the principal amount of any other such
Indebtedness (including the principal amount of commitments in respect of such Indebtedness) under which there has been a Payment Default or the maturity of which has been so accelerated (or commitments terminated) and remains undischarged after
such 30 day period, aggregates $25.0 million or more; 
 (g) failure by the Issuer and any of the Restricted
Subsidiaries to pay final judgments (other than any judgment as to which a reputable insurance company has accepted full liability) aggregating $25.0 million or more, which judgments are not stayed within 60 days after their entry; 

(h) any Guarantee of a Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last
Measurement Period, would constitute a Significant Subsidiary) shall be held in a judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any Guarantor that qualifies as a Significant
Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary), or any Person acting on behalf of any Guarantor that qualifies as a Significant Subsidiary (or a
group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary), shall deny or disaffirm its obligations under its Guarantee; 

(i) the Issuer or any Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last
Measurement Period, would constitute a Significant Subsidiary) of the Issuer pursuant to or within the meaning of Bankruptcy Law (i) commences a voluntary case or proceeding under Bankruptcy Law; (ii) consents to the entry of an order for
relief against it in an involuntary case or proceeding under Bankruptcy Law; (iii) consents to the appointment of a custodian, trustee, receiver, receiver and manager, monitor or interim receiver of it or for all or substantially all of its
property; or (iv) makes a general assignment for the benefit of its creditors; 
 (j) a court of competent jurisdiction
enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Issuer or any Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a
Significant Subsidiary) of the Issuer in an involuntary case or proceeding; (ii) appoints a custodian, trustee, receiver, receiver and manager, monitor or interim receiver of the Issuer or any Significant Subsidiary (or a group of Restricted

Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary) of the Issuer; or (iii) orders the liquidation of the Issuer or any Significant Subsidiary of the Issuer, and the order or decree
remains unstayed and in effect for 60 consecutive days; and 
 (k) any Collateral Document after delivery thereof shall for
any reason cease (or shall be asserted in writing by the Issuer or any Guarantor to cease) to create a valid and perfected first-priority Lien to the extent required by the Collateral Documents (subject to no other Liens other than Permitted Liens)
on Collateral that is (i) purported to be covered thereby and (ii) comprises Property which, when taken together with all Property as to which such a Lien has so ceased to be effective, has a fair market value in excess of
$25.0 million (other than (x) in accordance with the terms of this Indenture or the terms of the First Lien Intercreditor Agreement or the Collateral 

  
 -73- 

 
Documents or (y) except to the extent that any such cessation of the Liens results from the failure of the administrative agent under the Credit Facilities or the Applicable Authorized
Representative, as the case may be, in each case, as bailee for the Collateral Agent pursuant to the terms of the First Lien Intercreditor Agreement, to maintain possession of certificates actually delivered to it representing securities pledged
under the Collateral Documents). 
 However, a Default under Section 6.01(c), Section 6.01(d) or
Section 6.01(g) will not constitute an Event of Default until the Trustee or the holders of at least 25% in principal amount of the outstanding Notes notify the Issuer of the Default and, with respect to Section 6.01(c) or
Section 6.01(g), the Issuer does not cure such Default within the time specified in Section 6.01(c) or Section 6.01(g) after the occurrence of such Default; provided that a notice of Default may not be given with respect to any action
taken, and reported publicly or to holders, more than two years prior to such notice of Default. 
 Any failure to perform,
or breach of, any covenant or agreement pursuant to Section 4.03 shall not be a Default or an Event of Default until the 121st day after the Issuer has received the notice referred to in clause (d) of Section 6.01 (at which point,
unless cured or waived, such failure to perform or breach shall constitute an Event of Default). A failure to perform, or breach of any covenant or agreement pursuant to Section 4.03, shall automatically cease to be outstanding and shall be
deemed to be cured at such time as the Issuer furnishes or files the applicable information or report. 
 SECTION 6.02
Acceleration. 
 If any Event of Default occurs and is continuing, the Trustee, by notice to the
Issuer, or the Holders of at least 25% of the aggregate principal amount then outstanding of the Notes, by written notice to the Issuer and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in
the case of an Event of Default specified in paragraph (i) or (j) of Section 6.01 hereof with respect to the Issuer, all outstanding Notes shall become and shall be immediately due and payable without further action or notice. Holders of
the Notes may not enforce this Indenture or the Notes except as provided in this Indenture. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the
payment of principal or interest) if it determines that withholding notice is in such Holders’ interest. 
 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, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes and this Indenture and, subject to the First Lien Intercreditor Agreement, the Collateral
Agent may pursue any available remedy under the Collateral Documents. 
 The Trustee may maintain a proceeding even if it
does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee, the Collateral Agent or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 

SECTION 6.04 Waiver of Past Defaults. 

Holders of not less than a majority in aggregate principal amount of Notes then outstanding, by written notice to the Trustee,
may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences under this Indenture, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or
interest on, the Notes. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose hereof; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon. 
 SECTION 6.05 Control by Majority. 

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or the Collateral Agent or 

  
 -74- 

 
exercising any trust or power conferred on it. However, either the Trustee or the Collateral Agent may refuse to follow any direction that conflicts with the law or this Indenture that the
Trustee or the Collateral Agent, as applicable, determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee or the Collateral Agent in personal liability. 

SECTION 6.06 Limitation on Suits. 

A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 

(a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 

(b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to
pursue the remedy; 
 (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense; 
 (d) the Trustee does not comply with the request
within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 
 (e) during
such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or
priority over another Holder of a Note. 
 SECTION 6.07 Rights of Holders of Notes To Receive Payment. 

Notwithstanding any other provision hereof, the right of any Holder of a Note to receive payment of principal, premium, if any,
and interest on the Note, on or after the respective due dates expressed in the Note, 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 the Holder of
the Note. 
 SECTION 6.08 Collection Suit by Trustee. 

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

SECTION 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the
Issuer (or any other obligor upon the Notes), the Issuer’s creditors or the Issuer’s property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and
any custodian in any such judicial proceeding is hereby authorized by each Holder of a Note to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders of the Notes, to
pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee 

  
 -75- 

 
under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties which the Holders of the Notes may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Note any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder of
a Note thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Note in any such proceeding. 

SECTION 6.10 Priorities. 

Subject to the First Lien Intercreditor Agreement, if the Trustee or the Collateral Agent 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 and the Collateral Agent, their respective agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Collateral
Agent and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on
the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 

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

The Trustee may fix a record date and payment date for any payment to Holders of Notes. 

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 a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees 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 of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes pursuant to this Article 6. 

ARTICLE 7 
 TRUSTEE 

SECTION 7.01 Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of 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 his or her own affairs. 

(b) Except during the continuance of an Event of Default,

provision hereof to be furnished to it, the Trustee shall examine the certificates 

  
 -76- 

 
and opinions to determine whether or not they conform on their face to the requirements hereof but need not confirm or investigate the accuracy of mathematical calculations or other facts stated
therein.

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

(e) No provision hereof shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be
under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holders of Notes, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to the Trustee against any loss,
liability or expense. 
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee
may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

SECTION 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any document (whether in
original or facsimile form) 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; 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or
both (in each case, in accordance with Section 12.04). The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with

reliance thereon; 
 (c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct
or negligence of any agent appointed with due care; 
 (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or powers conferred upon it by this Indenture; 

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be
sufficient if signed by an Officer of the Issuer; 
 (f) The Trustee shall be under no obligation to exercise any of the

be incurred by it in compliance with such request or direction; 

  
 -77- 

 (g) The Trustee shall not be deemed to have notice of any Default or Event
of Default unless written notice of any event which is in fact such a default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes 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 may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Indenture; and 
 (j) 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. 
 (k) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate (including any Officers’ Certificate), statement, instrument, opinion (including any Opinion of Counsel), notice, request, direction, consent, order, bond, debenture, or other paper or
document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. 

SECTION 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the
Issuer or any Affiliate of the Issuer with the same rights it would have if it were not the Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for
permission to continue as Trustee (if any of the Notes are registered pursuant to the Securities Act), or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

SECTION 7.04 Trustee’s Disclaimer. 

(a) The Trustee shall not be responsible for and makes no representation as to the validity or adequacy hereof or the Notes, it
shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision hereof, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other

stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the
sole cost of the Issuer. 
 SECTION 7.05 Notice of Defaults.

accordance with Section 7.02(g), the Trustee shall mail or otherwise deliver to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the
Notes. 

  
 -78- 

 SECTION 7.06 Limitation on Duty in Respect of Collateral.

 Beyond the exercise of reasonable care in the custody thereof, neither the Collateral Agent nor the Trustee shall have any
duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or as to preservation of rights against prior parties or any other rights pertaining thereto. Neither the Collateral Agent nor the Trustee
shall be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the
Collateral. Each of the Trustee and the Collateral Agent shall be deemed to have exercised reasonable care with respect to the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Trustee or the
Collateral Agent, as applicable, accords its own property and neither the Trustee nor the Collateral Agent shall be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any
carrier, forwarding agency or other agent or bailee selected by the Trustee or the Collateral Agent in accordance with Section 7.02(c) or Section 11.07(b), as applicable. 

The Trustee and the Collateral Agent shall not be responsible (i) for the existence, genuineness or value of any of the
Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action
or omission constitutes gross negligence or willful misconduct on the part of the Trustee and the Collateral Agent, (ii) for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, (iii) for the
validity of the title of the Issuer to the Collateral, or (iv) for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral, in each case, except
with respect to stock certificates, stock powers or other possessory collateral delivered to the Collateral Agent to the extent required under the Collateral Documents. The Trustee and the Collateral Agent shall have no duty to ascertain or inquire
as to the performance or observance of any of the terms of this Indenture, the First Lien Intercreditor Agreement, the Junior Lien Intercreditor Agreement (if any) or the Collateral Documents by the Issuer, any Guarantor, or the Credit Agreement
Collateral Agent. 
 SECTION 7.07 Compensation and Indemnity. 

The Issuer shall pay to the Trustee and Collateral Agent from time to time reasonable compensation for its acceptance hereof
and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee and Collateral Agent promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s and Collateral Agent’s
agents and counsel. 
 The Issuer shall indemnify each of the Trustee and Collateral Agent and their respective agents,
employees, officers, stockholders and directors for, and hold them harmless against any and all losses, liabilities, claims, damages or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under
this Indenture (including any other Note Document) including enforcement of this Section 7.07, except any such loss, liability, claim, damage or expense as shall be determined to have been caused by the negligence or willful misconduct of the
Trustee or the Collateral Agent. Each of the Trustee and Collateral Agent shall notify the Issuer promptly of any claim of which a Responsible Officer has received written notice for which it may seek indemnity. Failure by the Trustee and Collateral
Agent to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee and Collateral Agent shall cooperate in the defense. The Trustee and Collateral Agent may have separate
counsel and the Issuer shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer shall not be required to pay such fees and expenses if the Issuer assumes such defense unless there is a conflict of
interest between the Issuer and the Trustee in connection with such defense as determined by Trustee in consultation with counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

 The obligations of the Issuer under this Section 7.07 shall survive the satisfaction and discharge hereof or the
earlier resignation or removal of the Trustee. 

  
 -79- 

 To secure the Issuer’s payment obligations in this Section 7.07,
the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge hereof.

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

SECTION 7.08 Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.08. 
 The Trustee may resign in writing at any
time upon 30 days written notice and be discharged from the trust hereby created by so notifying the Issuer. The Holders of at least a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and
the Issuer with 30 days prior notice. The Issuer may remove the Trustee if upon 30 days written notice: 
 (a) the Trustee
fails to comply with Section 7.10 hereof; 
 (b) the Trustee is adjudged a bankrupt or an insolvent person, within the
meaning of Bankruptcy Law, or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 
 (c) a
custodian or public officer takes charge of the Trustee or its property; or 
 (d) the Trustee becomes incapable of acting.

 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall
promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by
the Issuer. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed,
the retiring Trustee, the Issuer or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition at the expense of the Issuer any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee after written request by any Holder of a Note who has been a Holder of a Note for at least six months fails to
comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer.
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 mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for
in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 

If a Trustee resigns or is removed all fees and expenses of the Trustee incurred in the administration of the trust or in the
performance of the duties hereunder shall be paid to the Trustee. 

  
 -80- 

 SECTION 7.09 Successor Trustee by Merger, Etc. 

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to,
another corporation, the successor corporation without any further act shall be the successor Trustee. 
 SECTION 7.10
Eligibility; Disqualification. 
 There shall at all times be a Trustee hereunder which shall be
a corporation organized and doing business under the laws of the United States of America or of any state thereof authorized under such laws to exercise corporate trustee power, shall be subject to supervision or examination by federal or state
authority and shall have a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. 

SECTION 7.11 Collateral Documents; Intercreditor Agreements. 

By their acceptance of the Notes, the Holders hereby authorize and direct the Trustee and the Collateral Agent, as the case may
be, to execute and deliver the First Lien Intercreditor Agreement, any Junior Lien Intercreditor Agreement in respect of permitted Junior Lien Obligations and any other Collateral Documents in which the Trustee or the Collateral Agent, as
applicable, is named as a party, including any Collateral Documents executed after the Issue Date. It is hereby expressly acknowledged and agreed that, in doing so, the Trustee and the Collateral Agent are (a) expressly authorized to make the
representations attributed to Holders in any such agreements and (b) not responsible for the terms or contents of such agreements, or for the validity or enforceability thereof, or the sufficiency thereof for any purpose. Whether or not so
expressly stated therein, in entering into, or taking (or forbearing from) any action under, the First Lien Intercreditor Agreement, any Junior Lien Intercreditor Agreement or any other Collateral Documents, the Trustee and the Collateral Agent each
shall have all of the rights, immunities, indemnities, privileges and other protections granted to it under this Indenture and the Collateral Documents (in addition to those that may be granted to it under the terms of such other agreement or
agreements). 
 ARTICLE 8 

DISCHARGE OF INDENTURE; DEFEASANCE 

SECTION 8.01 Termination of the Issuer’s Obligations. 

(a) The Issuer may terminate its Obligations as to all outstanding Notes and the Liens on Collateral securing the Notes shall
be released, except those obligations referred to in paragraph (b) of this Section 8.01, when 

(1) either: 

(a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have
been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for
cancellation; or 
 (b) all Notes not theretofore delivered to the Trustee for cancellation have become due
and payable or, within one year will become due and payable or subject to redemption as set forth in Section 3.07 and the Issuer has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and
discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Issuer
directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; 

(2) the Issuer has paid all other sums payable under this Indenture by the Issuer; and 

  
 -81- 

 (3) the Issuer has delivered to the Trustee and the
Collateral Agent an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge hereof have been complied with; provided, however, that such
counsel may rely, as to matters of fact, on a certificate or certificates of Officers of the Issuer. 
 (b) Notwithstanding
paragraph (a) of this Section 8.01, the Issuer’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 7.07, 7.08, 8.07 and 8.08 hereof, and the rights, powers, trust, duties and immunities of the Trustee and the Collateral Agent, and
the Issuer’s obligations in connection therewith, shall survive until the Notes are no longer outstanding pursuant to Section 2.08 hereof. After the Notes are no longer outstanding, the Issuer’s obligations in Sections 7.07,
7.08, 8.07 and 8.08 hereof shall survive such satisfaction and discharge. 
 SECTION 8.02 Option To Effect Legal Defeasance or
Covenant Defeasance. 
 The Issuer may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers’ Certificate, at any time, with respect to the Notes, elect to have either Section 8.03 or 8.04 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article
8. 
 SECTION 8.03 Legal Defeasance and Covenant Discharge. 

Upon the Issuer’s exercise under Section 8.02 hereof of the option applicable to this Section 8.03, the Issuer
shall be deemed to have been discharged from their obligations with respect to all outstanding Notes, each Guarantor’s obligation shall be discharged with respect to its Guarantee and the Liens on the Collateral securing the outstanding Notes
shall be automatically terminated and released on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Issuer shall be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.06 hereof and the other Sections hereof referred to in clauses
(a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the
following, which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments
are due, or on the redemption date, as the case may be; (b) the Issuer’s obligations with respect to such Notes under Sections 2.05, 2.07, 2.08, 2.10, 2.11 and 4.02 hereof; (c) the rights, powers, trust, duties and immunities of the
Trustee and the Collateral Agent hereunder, and the Issuer’s obligations in connection therewith; and (d) this Section 8.03. Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.03
notwithstanding the prior exercise of its option under Section 8.04 hereof with respect to the Notes. 
 SECTION 8.04
Covenant Defeasance. 
 Upon the Issuer’s exercise under Section 8.02 hereof of the
option applicable to this Section 8.04, the Issuer shall be released from its obligations under the covenants contained in Sections 3.08, 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 (other than existence of the Issuer
(subject to Section 5.01), 4.15, 4.17, 4.18, 5.01 (except clauses (a) and (b)) and 10.03 hereof with respect to the outstanding Notes and the Liens on Collateral securing the outstanding Notes shall be automatically terminated and released
on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed
outstanding for IFRS). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall
not constitute a Default or an Event of Default under Section 6.01(c) hereof, but, except as specified above, the remainder hereof and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.02
hereof of the option applicable to this Section 8.04, Sections 6.01(c) through 6.01(g) shall not constitute Events of Default. 

  
 -82- 

 SECTION 8.05 Conditions to Legal or Covenant Defeasance.

 The following shall be the conditions to the application of either Section 8.03 or Section 8.04 hereof to the
outstanding Notes: 
 (a) the Issuer shall have irrevocably deposited with the Trustee, in trust, for the benefit of the
Holders of the Notes, cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding Notes on the stated maturity or on the applicable optional redemption date, as the case may be; 

(b) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States
confirming that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in each case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the beneficial owners of the Notes 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 in the same amount, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(c) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel confirming that
the beneficial owners of the Notes 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; 
 (d) in the case of Legal Defeasance
or Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel or an advance tax ruling from the Canada Revenue Agency (or successor agency), in each case to the effect that the holders and beneficial owners of the
Notes will not recognize income, gain, or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of such Legal Defeasance or Covenant Defeasance, as the case may be, and will be subject to Canadian federal,
provincial or territorial income or other tax on the same amounts, in the same manner, and at the same times as would have been the case if such Legal Defeasance or Covenant Defeasance, as the case may be, had not occurred; 

(e) no Default or Event of Default shall have occurred and be continuing on the date of such deposit; 

(f) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under,
this Indenture or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound; 

(g) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit made by the Issuer
pursuant to its election under Section 8.03 and 8.04 hereof was not made by the Issuer with the intent of preferring the Holders of the Notes over any of its other creditors or with the intent of defeating, hindering, delaying or defrauding any
of its other creditors or others; and 
 (h) the Issuer shall have delivered to the Trustee an Officers’ Certificate and
Opinion of Counsel stating that all conditions precedent provided for or relating to the Legal Defeasance under Section 8.03 hereof or the Covenant Defeasance under Section 8.04 hereof (as the case may be) have been complied with as
contemplated by this Section 8.05. 
 SECTION 8.06 Deposited Money and Government Securities To Be Held in Trust; Other
Miscellaneous Provisions. 
 Subject to Section 8.07 hereof, all money and Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.06, the “Trustee”) pursuant to Section 8.05 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, 

  
 -83- 

 
in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

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

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time
upon the request of the Issuer any money or Government Securities held by it as provided in Section 8.05 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.05(a) hereof), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

SECTION 8.07 Repayment to Issuer. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal
of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Issuer on their request or (if then held by the Issuer) shall
be discharged from such trust; and the Holder of such Note shall thereafter, as a general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Issuer as trustees thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published
once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication,
any unclaimed balance of such money then remaining will be repaid to the Issuer. 
 SECTION 8.08
Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any United States Dollars or
Government Securities in accordance with Section 8.03 or 8.04 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the
Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.03 or 8.04 hereof until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.03 or 8.04 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its
obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9

Notwithstanding Section 9.02 hereof, the Issuer, the Guarantors and the Trustee and the Collateral Agent (as applicable)

Code);

 (m) with respect to the Collateral Documents and the First Lien Intercreditor Agreement,
as provided in the relevant Collateral Document or First Lien Intercreditor Agreement. 
 Upon the request of the Issuer
accompanied by a resolution of the Board of Directors of the Issuer and a resolution of the Board of Directors of each Guarantor and upon receipt by the Trustee and Collateral Agent of the documents described in Sections 7.02, 9.06 and 11.04 hereof,
the Trustee and Collateral Agent shall join with the Issuer and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and shall make any further appropriate agreements and
stipulations which may be therein contained, but neither the Trustee nor the Collateral Agent shall be obligated to enter into such amended or supplemental indenture or any amendment or supplement to the Notes, the Guarantees, any Collateral
Document, the First Lien Intercreditor Agreement or any Junior Lien Intercreditor Agreement which affects its own rights, duties or immunities under this Indenture or otherwise. 

SECTION 9.02 With Consent of Holders of Notes. 

The Issuer, the Guarantors and the Trustee and/or Collateral Agent (as applicable) may amend or supplement this Indenture, the
Notes, the Guarantees, the Collateral Documents, the First Lien Intercreditor Agreement and 

  
 -85- 

 
any Junior Lien Intercreditor Agreement or any amended or supplemental indenture or any amendment or supplement to the Notes, the Guarantees, any Collateral Document, the First Lien Intercreditor
Agreement or any Junior Lien Intercreditor Agreement with the written consent of the Holders of at least a majority of the aggregate principal amount of Notes then outstanding (including consents obtained in connection with an exchange offer or
tender offer for the Notes), and any existing Default and its consequences or compliance with any provision of this Indenture, the Notes, any Collateral Document, the First Lien Intercreditor Agreement or any Junior Lien Intercreditor Agreement may
be waived with the consent of the Holders of a majority of the aggregate principal amount of Notes then outstanding (including consents obtained in connection with an exchange offer or tender offer for the Notes). Notwithstanding the foregoing,
without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder): 

(a) reduce the aggregate principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

(b) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of
the Notes (other than as provided in clause (h) below); 
 (c) reduce the rate of or change the time for payment of
interest on any Note; 
 (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or
interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(f) make any change in the provisions hereof relating to waivers of past Defaults or the rights of Holders of Notes to receive

(i) release all or substantially all of the Guarantees of the Guarantors other than in accordance with Article 10; 

(j) make any change in the foregoing amendment and waiver provisions; 

(k) impair the right to institute suit for the enforcement of any payment on or with respect to the Notes or the Guarantees; or

 (l) subordinate the payment of the Notes or Guarantees to any other obligation of the Issuers or the Guarantors. 

Upon the request of the Issuer accompanied by a resolution of the Board of Directors of the Issuer and a resolution of the
Board of Directors of each Guarantor, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Sections 7.02, 9.06
and 11.04 hereof, the Trustee shall join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture or amended or supplemental indenture or any amendment or supplement to the Notes, the Guarantees, any Collateral
Document, the First Lien Intercreditor Agreement or any Junior Lien Intercreditor Agreement unless such amended or supplemental indenture or amendment or supplement to the Notes, the Guarantees, any Collateral Document, the First Lien Intercreditor
Agreement or any Junior Lien Intercreditor Agreement affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in 

  
 -86- 

 
which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture or such amendment or supplement to the Notes, the Guarantees, any
Collateral Document, the First Lien Intercreditor Agreement or any Junior Lien Intercreditor Agreement. 
 It shall not be
necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders
of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Issuer with any provision of this Indenture or
of the Notes. 
 Notwithstanding the foregoing, without the consent of holders of at least 66 2/3% in aggregate principal
amount of the Notes then outstanding, no amendment or waiver may (i) release all or substantially all of the Collateral from the Liens securing the Notes Obligations created by the Collateral Documents or (ii) change or alter the priority
of the Liens securing the Notes Obligations created by the Collateral Documents in any manner adverse to the holders of the Notes or (iii) make any change in the First Lien Intercreditor Agreement, Junior Lien Intercreditor Agreement or in the
provisions of this Indenture or any Collateral Document dealing with the application of proceeds of the Collateral that would materially adversely affect the Holders or alter the priority of the security interests in the Collateral. 

SECTION 9.03 [Reserved]. 

SECTION 9.04 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by
the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or
subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in
accordance with its terms and thereafter binds every Holder of a Note. 
 The Issuer may fix a record date for determining
which Holders of the Notes must consent to such amendment, supplement or waiver. If the Issuer fixes a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the
most recent list of Holders of Notes furnished to the Trustee prior to such solicitation pursuant to Section 2.05 hereof or (ii) such other date as the Issuer shall designate. 

SECTION 9.05 Notation on or Exchange of Notes. 

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

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver. 
 SECTION 9.06 Trustee, Collateral Agent To Sign Amendments, Etc. 

In executing, or accepting the additional trusts created by, any amendment, supplement or waiver permitted by this Article or
the modification thereby of the trusts created by this Indenture, each of the Trustee and Collateral 

  
 -87- 

 
Agent, as applicable, shall receive, and shall by fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that the execution of such amendment, supplement
or waiver is authorized or permitted by this Indenture. The Trustee and Collateral Agent may, but shall not be obligated to, enter into any such amendment, supplement or waiver which affects, as the case may be, the Trustee’s or Collateral
Agent’s own rights, duties or immunities under this Indenture, the Collateral Documents or the First Lien Intercreditor Agreement or otherwise. 

ARTICLE 10 
 GUARANTEES 

SECTION 10.01 Guarantee. 

Subject to this Article 10, each of the Guarantors, jointly and severally, hereby unconditionally guarantees to each Holder of
a Note authenticated and delivered by the Trustee and to the Trustee and the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Issuer
hereunder or thereunder, that: 
 (a) the principal of, premium, if any, and interest on the Notes will be promptly paid in
full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other Obligations of the Issuer to the Holders or the Trustee hereunder or
thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (b) in
case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, each of the Guarantors, jointly and severally, will be obligated to pay the same immediately. 

Each of the Guarantors, jointly and severally, hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of a Note with respect to any provisions hereof or thereof, the recovery of
any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

Each of the Guarantors, jointly and severally, hereby waives diligence, presentment, demand of payment, filing of claims with
a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete
performance of the Obligations guaranteed hereby. If any Holder or the Trustee is required by any court or otherwise, or any custodian, Trustee, liquidator or other similar official acting in relation to either the Issuer or any Guarantor, to return
to the Issuer or any Guarantor any amount paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 

Each of the Guarantors, jointly and severally, agrees that it shall not be entitled to any right of subrogation in relation to
the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each of the Guarantors, jointly and severally, further agrees that, as between such Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article 6, such Obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of this Guarantee unless subsequently rescinded as set forth therein. Notwithstanding the foregoing, in the event that any Guarantee would constitute or result in a violation of any applicable fraudulent
conveyance or similar law of any relevant jurisdiction, the liability of the applicable Guarantor under its Guarantee shall be reduced to the maximum amount permissible under such fraudulent conveyance or similar law. 

  
 -88- 

 The Guarantors hereby agree as among themselves that each Guarantor that
makes a payment or distribution under a 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 hereunder based on the respective net worth of all the Guarantors at the time of such payment determined in accordance with IFRS. The preceding sentence shall in no way affect the rights of the Holders of Notes, the Trustee
or the Collateral Agent to the benefits hereof, the Notes, the Guarantees or the Collateral Documents. 
 Nothing contained
in this Section 10.01 or elsewhere in this Indenture, the Notes or the Guarantees shall impair, as between any Guarantor and the Holder of any Note, the obligation of such Guarantor, which is unconditional and absolute, to pay to the Holder
thereof the principal of, premium, if any, and interest on such Notes in accordance with their terms and the terms of the Guarantee and this Indenture, nor shall anything herein or therein prevent the Trustee, the Collateral Agent or the Holder of
any Note from exercising all remedies otherwise permitted by applicable law or hereunder or thereunder upon the occurrence of an Event of Default. 

SECTION 10.02 Execution and Delivery of Guarantees. 

To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be
executed on behalf of such Guarantor by any of its Officers (or, with respect to any Guarantor that provides a Guarantee after the Issue Date, as set forth in Section 4.13). The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors. 

SECTION 10.03 Merger, Consolidation or Sale of Assets of Guarantors. 

Subject to Section 10.05 hereof, a Guarantor may not, and the Issuer shall not cause or permit any Guarantor to,
consolidate, amalgamate, participate in an arrangement with or merge with or into (whether or not such Guarantor is the surviving entity), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or
assets in one or more related transactions to, another Person other than the Issuer or another Guarantor (in each case other than in accordance with Section 4.10) unless: 

(a) such Guarantor is the surviving Person or the Person formed by or surviving any such consolidation, amalgamation,
arrangement or merger (if other than the Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, limited partnership or limited liability company organized or existing
under the laws of the United States, any state thereof or the District of Columbia; 
 (b) the Person formed by or surviving
any such consolidation, amalgamation or merger (if other than the Guarantor) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Guarantor under this
Indenture, the Notes, the Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement) pursuant to a supplemental indenture and joinders or supplements, as applicable, to the
Collateral Documents and the First Lien Intercreditor Agreement (and, if applicable, any Junior Lien Intercreditor Agreement), in each case, in form reasonably satisfactory to the Trustee and the Collateral Agent; and 

(c) immediately after such transaction, no Event of Default exists. 

Nothing contained in this Indenture shall prevent any consolidation or merger of a Guarantor with or into the Issuer or
another Guarantor that is a wholly owned Restricted Subsidiary of the Issuer or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor that is a wholly
owned Restricted Subsidiary of the Issuer. Except as set forth in Articles 4 and 5 hereof, nothing contained in this Indenture shall prevent any consolidation or merger of a Guarantor with or into the Issuer or another Guarantor that is a Restricted
Subsidiary of the Issuer or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor that is a Restricted Subsidiary of the Issuer. 

  
 -89- 

 SECTION 10.04 Successor Corporation Substituted. 

Upon any consolidation, amalgamation, arrangement, merger, sale or conveyance described in paragraphs (a) through (c) of
Section 10.03 hereof, and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of any Guarantee previously signed by the Guarantor and the due and
punctual performance of all of the covenants and conditions hereof to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such
successor Person thereupon may cause to be signed any or all of the Guarantees to be issuable hereunder by such Guarantor and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under
this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution of such Guarantee by such Guarantor. When a successor
Person assumes all the obligations of the Issuer under the Notes and this Indenture pursuant to Article 5 hereof, the applicable predecessor shall be released from the obligations so assumed. 

SECTION 10.05 Releases from Guarantees. 

A Guarantor shall be released and relieved of its obligations under its Guarantee upon: 

(1) in connection with any direct or indirect sale, conveyance or other disposition of all the Capital Stock of such Guarantor
(including any such sale, conveyance or other disposition after which such Guarantor is no long a Restricted Subsidiary and excluding any sale, conveyance or other disposition of the Capital Stock of a Professional Services Affiliate to another
Person if such Professional Services Affiliate remains a Restricted Subsidiary) or of all or substantially all of the assets and property of such Guarantor, if such sale or disposition is made in compliance with Section 4.10; 

(2) such Guarantor is liquidated in accordance with the provisions hereof; 

(3) the Issuer designates any such Guarantor as an Unrestricted Subsidiary in compliance with the terms of this Indenture;

 (4) with respect to any Guarantor that initially provided its guarantee of the Notes pursuant to Section 4.13 (which,
for the avoidance of doubt, does not include any Guarantor as of the Issue Date), upon the release or discharge (other than a release or discharge by or as a result of payment under such guarantee or payment in full of such Indebtedness) of the
guarantee by such Guarantor of the Indebtedness that resulted in the requirement for such Guarantor to provide its guarantee of the Notes; or 

(5) upon the satisfaction and discharge of this Indenture in accordance with Section 8.01 or upon any Legal Defeasance or
Covenant Defeasance. 
 For the avoidance of doubt, no Guarantee of a Guarantor shall be released as a result of the
issuance or sale of Preferred Equity Interests in a Restricted Subsidiary to a Strategic Partner. 
 Upon delivery by the
Issuer to the Trustee and the Collateral Agent of an Officers’ Certificate and an Opinion of Counsel to the effect that all the conditions precedent to such sale or other disposition have been complied with or that such Guarantor has been
released from its obligations under its Guarantee in accordance with any other provision of this Section 10.05, the Trustee and the Collateral Agent shall execute any documents pursuant to written direction of the Issuer in order to evidence
the release of any such Guarantor from its obligations under its Guarantee. Any such Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other

trustee, and an instrument signed by such receiver, interim receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or a Guarantor or of any Officer or Officers thereof required by the provisions of this Article

SECTION 11.07 Collateral Agent. 

(a) Each of the Holders by acceptance of the Notes hereby designates and appoints the Collateral Agent as its agent under this
Indenture, the Collateral Documents, the First Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement, if any, and each of the Holders by acceptance of the Notes and the Trustee hereby irrevocably authorizes the Collateral Agent to
take such action on their behalf under the provisions of this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement, if any, and to exercise such powers and perform such duties as are
expressly delegated to the Collateral Agent by the terms of this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement, if any, and consents and agrees to the terms of the First Lien
Intercreditor Agreement, the Junior Lien Intercreditor Agreement, if any, and each Collateral Document, as the same may be in effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with their
respective terms. The Collateral Agent accepts such appointment and agrees to act as such on the express conditions contained in this Section 11.07. Each Holder agrees that any action taken by the Collateral Agent in accordance with the
provisions of this Indenture, the First Lien Intercreditor Agreement, the Junior Lien Intercreditor Agreement, if any, and the Collateral Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein
shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement, if
any, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other Notes Documents to which the
Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, the Issuer or any Guarantor, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement, if any, or otherwise exist, against the Collateral Agent. Without limiting
the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine
of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

 (b) The Collateral Agent may perform any of its duties under this Indenture,
the Collateral Documents, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, by or through receivers, agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel of its selection concerning all matters pertaining to such duties, and shall be entitled to act upon, and
shall be fully protected in taking action in reliance upon any advice or opinion given by such counsel. The Collateral Agent shall not be responsible for the negligence or misconduct of any receiver, agent, employee or
attorney-in-fact that it selects as long as such selection was made in good faith and with due care.

with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful misconduct) or under or in connection with any Collateral Document, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor
Agreement, if any, or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Trustee or any Holder for any recital, statement, representation,
warranty, covenant or agreement made by the Issuer or any other Guarantor or Affiliate of any Guarantor, or any Officer thereof, contained in this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement, or the Junior Lien
Intercreditor Agreement, if any, or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture, the Collateral Documents, the First Lien
Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement or the Junior
Lien Intercreditor Agreement, if any, or for any failure of the Issuer, any Guarantor or any other party to this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, to
perform its obligations hereunder or thereunder. The Collateral Agent shall not be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions
of, this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, or to inspect the properties, books, or records of the Issuer, any Guarantor or any of their Affiliates. 

(d) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution,
notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication, document or conversation (including those by telephone or e-mail)
believed by it to be genuine and correct and to have been signed, sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the Issuer or any Guarantor), independent

notice, request, direction, consent, order, bond, debenture, or other paper or document. The Collateral Agent shall be fully justified in failing or refusing to take any action under this Indenture, the Collateral Documents, the First Lien
Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, unless it shall first receive such written direction or consent of the Holders of a majority in aggregate principal amount of the Notes and, if it so requests, it shall
first be indemnified to its satisfaction by the Holders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, in accordance with a request, direction, instruction or consent of the
Trustee or the Holders of a majority in aggregate principal amount of the then outstanding Notes and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders. 

(e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any default or Event of Default,
unless a Responsible Officer of the Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such Event of Default and stating that such notice is a “notice of default.” The
Collateral Agent shall take such action with respect to such Event of Default as may be requested in accordance with, and subject to the provisions of, Article 6 by the Trustee or the Holders of a majority in aggregate principal amount of the Notes
(subject to this Section 11.07 and the terms of the First Lien Intercreditor Agreement and any Junior Lien Intercreditor Agreement).

 (f) The Collateral Agent may resign at any time upon 30 days’ advance
written notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Issuer shall appoint a
successor collateral agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, at the direction of
the Holders of a majority of the aggregate principal amount of the Notes then outstanding, a successor collateral agent, subject to the consent of the Issuer (which consent shall not be unreasonably withheld and which shall not be required during a
continuing Event of Default). If no successor collateral agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty (30) days after the intended effective date of resignation (as stated in the notice of
resignation) the Collateral Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor collateral agent hereunder, such successor collateral agent shall succeed
to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral
Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder, the provisions of this Section 11.07 (and Section 7.07 hereof) shall continue to inure to its benefit and the retiring Collateral Agent shall not
by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Indenture, the First Lien Intercreditor Agreement or any Junior Lien
Intercreditor Agreement.

realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral
or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be
responsible for any act or failure to act hereunder, except for its own gross negligence or willful misconduct.

Lien Intercreditor Agreement on the Issue Date, (iii) enter into the Junior Lien Intercreditor Agreement, if any, after the Issue Date, (iv) make the representations of the Holders set forth in the Collateral Documents, the First Lien

Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent such proceeds to be applied by the Collateral Agent pursuant to the terms of this Indenture, the Collateral Documents, the First
Lien Intercreditor Agreement and the Junior Lien Intercreditor Agreement (if any). 
 (j) The Collateral Agent is each
Holder’s agent for the purpose of perfecting the Holders’ security interest in assets which, in accordance with Article 9 of the UCC or the comparable section of the PPSA, can be perfected only by possession. Should the Trustee obtain
possession of any such Collateral, upon request from the Issuer, the Trustee shall notify the Collateral Agent thereof and promptly shall deliver such Collateral to the Collateral Agent or otherwise deal with such Collateral in accordance with the
Collateral Agent’s instructions. 

  
 -95- 

 (k) The Collateral Agent shall have no obligation whatsoever to the Trustee
or any of the Holders to assure that the Collateral exists or is owned by the Issuer, any Guarantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or
lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all or the Issuer’s or any Guarantor’s property constituting Collateral intended to be subject to the Lien
and security interest of the Collateral Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any
particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture, any Collateral Document, the First
Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, other than pursuant to the instructions of the Trustee or the Holders of a majority in aggregate principal amount of the Notes or as otherwise provided in the
Collateral Documents. Neither the Trustee nor the Collateral Agent shall have a duty or obligation to monitor the condition, financial or otherwise, of the Issuer or any Guarantor. 

(l) If the Issuer or any Guarantor (i) incurs any obligations in respect of First Lien Obligations or Junior Lien
Obligations at any time when no applicable intercreditor agreement is in effect or at any time when Indebtedness constituting First Lien Obligations or Junior Lien Obligations entitled to the benefit of an existing First Lien Intercreditor Agreement
or Junior Lien Intercreditor Agreement is concurrently retired, and (ii) delivers to the Collateral Agent an Officer’s Certificate so stating and requesting the Collateral Agent to enter into an intercreditor agreement (on substantially
the same terms as the First Lien Intercreditor Agreement or, in the case of the Junior Lien Intercreditor Agreement, in customary market form (as reasonably determined by the Issuer as set forth in an Officer’s Certificate delivered to the
Trustee and the Collateral Agent)) in favor of a designated agent or representative for the holders of the First Lien Obligations or Junior Lien Obligations so incurred, the Collateral Agent shall (and is hereby authorized and directed to) enter
into such intercreditor agreement (at the sole expense and cost of the Issuer, including reasonable legal fees and expenses of the Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder.

 (m) No provision of this Indenture, the First Lien Intercreditor Agreement, the Junior Lien Intercreditor Agreement, if
any, or any Collateral Document shall require the Collateral Agent or 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 thereunder or to take or omit to take
any action hereunder or thereunder or take any action at the request or direction of Holders unless it shall have received indemnity satisfactory to the Collateral Agent against potential costs and liabilities incurred by the Collateral Agent
relating thereto. 
 Notwithstanding anything to the contrary contained in this Indenture, the First Lien Intercreditor
Agreement, the Junior Lien Intercreditor Agreement, if any, or the Collateral Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession
of the Collateral, the Collateral Agent shall not be required to commence any such action or exercise any remedy or to inspect or conduct any studies of any property under the mortgages or take any such other action if the Collateral Agent has
determined that the Collateral Agent may incur personal liability as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances in an amount and in a form all satisfactory to the Collateral Agent
in its sole discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease taking any action described in this clause (m) if it no longer reasonably deems any indemnity, security
or undertaking from the Issuer or the Holders to be sufficient. 
 (n) The Collateral Agent (i) shall not be liable for
any action taken or omitted to be taken by it in connection with this Indenture, the First Lien Intercreditor Agreement, the Junior Lien Intercreditor Agreement, if any, and the Collateral Documents or instrument referred to herein or therein,
except to the extent that any of the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct,
(ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent
required by law) and (iii) may consult with counsel of its selection and the advice or opinion of such counsel shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it in
good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

otherwise constitute any participation in the management of such Collateral, as those terms are defined in Section 101(20)(E) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. §§ 9601 et seq., as
amended.

give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any Collateral Document, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, the
Collateral Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with
the direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. If the Collateral Agent shall request direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes with
respect to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes,
and the Collateral Agent shall not incur liability to any Person by reason of so refraining. 
 (v) Notwithstanding anything
to the contrary in this Indenture, in any Collateral Document, the First Lien Intercreditor Agreement or the Junior Lien Intercreditor Agreement, if any, in no event shall the Collateral Agent or the Trustee be responsible for, or have any duty or
obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement or
the Junior Lien Intercreditor Agreement, if any (including, without limitation, the filing or continuation of any UCC and PPSA financing, financing change or continuation statements or similar documents or instruments), nor shall the Collateral
Agent or the Trustee be responsible for, and neither the Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Collateral Documents or the security interests or Liens intended to
be created thereby. 
 (w) Before the Collateral Agent acts or refrains from acting in each case at the request or direction
of the Issuer or the Guarantors, or in connection with any Collateral Document, the First Lien Intercreditor Agreement or any Junior Lien Intercreditor Agreement, it may require an Officer’s Certificate and an Opinion of Counsel, which shall
conform to the provisions of this Section 11.07 and Section 12.04 hereof. The Collateral Agent shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion.

Collateral Agent as the person acting as hypothecary representative holding the aforesaid hypothecs as aforesaid and to have ratified as of the date it becomes a holder, all actions taken by the Collateral Agent in such capacity. The substitution of
the Collateral Agent pursuant to the provisions hereof shall also constitute the substitution of the Collateral Agent as hypothecary representative as aforesaid without any further act or formality being required to appoint such successor Collateral
Agent as the successor hypothecary representative for the purposes of any then-existing deeds of hypothec.

 (Back of Note) 

Capitalized terms used herein have the meanings assigned to them in the Indenture (as defined below) unless otherwise
indicated. 
 (1) Interest. Akumin Inc., an Ontario corporation (the “Issuer”) promises to pay
interest on the principal amount of this Note at the rate and in the manner specified below. Interest will accrue at 7.000% per annum and will be payable semi-annually in cash on each May 1 and November 1, commencing May 1, 2021, or
if any such day is not a Business Day on the next succeeding Business Day (each, an “Interest Payment Date”) to Holders of record of the Notes at the close of business on the immediately preceding April 15 and October 15,
whether or not a Business Day. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. Interest shall accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the date of original issuance. To the extent lawful, the Issuer shall pay interest on overdue principal at the rate of the then applicable interest rate on the Notes; it
shall pay interest on overdue installments of interest (without regard to any applicable grace periods) at the same rate to the extent lawful. 

(2) Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are
registered Holders of Notes at the close of business on the record date next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date. The Issuer will 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. The Notes will be payable both as to principal and interest at the office or agency of the Issuer maintained for such purpose
or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders of Notes at their respective addresses set forth in the register of Holders of Notes. Unless otherwise designated by the Issuer, the Issuer’s office
or agency will be the office of the Trustee maintained for such purpose. 
 (3) Paying Agent and Registrar. Initially,
the Trustee will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar or co-registrar without prior notice to any Holder of a Note. The Issuer may act in any such capacity. 

(4) Indenture. The Issuer issued the Notes under an Indenture, dated as of November 2, 2020 (the
“Indenture”), among the Issuer, the Guarantors, and UMB Bank, National Association, as trustee (in such capacity, the “Trustee”) and as notes collateral agent (in such capacity, the “Collateral
Agent”). This is one of an issue of Notes of the Issuer issued, or to be issued, under the Indenture. The Issuer shall be entitled to issue additional Notes pursuant to Section 2.02 of the Indenture. All Notes issued under the
Indenture shall be treated as a single class of Notes under the Indenture. The terms of the Indenture shall govern any inconsistencies between the Indenture and the Notes. The Notes are senior secured obligations of the Issuer and the Guarantors,
secured by a first-priority security interest in the Collateral. 
 (5) Optional Redemption. 

(a) Except as provided in paragraphs (b) and (c) below and clause (6) below, the Notes will not be redeemable at the
Issuer’s option prior to November 1, 2022. Thereafter, the Notes will be subject to redemption at the option of the Issuer, in whole or in part, upon not less than 10 days’ or more than 60 days’ notice, at the redemption prices
(expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon to the applicable redemption date (subject to the rights of Holders of record of the Notes on the relevant record date to receive
payments of interest on the related interest payment date), if redeemed during the 12-month period beginning on November 1 of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2022
	  	 	103.500	% 
	 2023
	  	 	101.750	% 
	 2024 and thereafter
	  	 	100.000	% 

 (b) Notwithstanding the foregoing, at any time and from time to time prior
to November 1, 2022, the Issuer may redeem up to 40% of the original aggregate principal amount of the Notes outstanding at a redemption price equal to 107.000% of the principal amount thereof on the repurchase date, together with accrued and
unpaid interest to such redemption date (subject to the rights of Holders of record of the Notes on the relevant record date to receive payments of interest on the related interest payment date), with an amount equal to the net cash proceeds of one
or more public or private sales of Qualified Capital Stock (each, an “Equity Offering”), other than proceeds from a sale to the Issuer or any of its Subsidiaries or any employee benefit plan in which the Issuer or any of its
Subsidiaries participates; provided that (i) at least 60% in aggregate principal amount of the Notes originally issued remains outstanding immediately after the occurrence of such redemption (including additional Notes but excluding
Notes held by the Issuer or any of its Restricted Subsidiaries) unless all such Notes are redeemed substantially concurrently and (ii) such redemption occurs no later than the 120th day following such sale of Qualified Capital Stock. 

(c) In addition, at any time and from time to time prior to November 1, 2022, the Issuer may redeem all or any portion of
the Notes outstanding at a redemption price equal to (i) 100% of the aggregate principal amount of the Notes to be redeemed, together with accrued and unpaid interest to such redemption date (subject to the rights of Holders of record of the
Notes on the relevant record date to receive payments of interest on the related interest payment date), plus (ii) the Make Whole Amount. 

“Make Whole Amount” means, with respect to any Note at any redemption date, as determined by the Issuer, the
greater of (i) 1.0% of the principal amount of such Note and (ii) the excess, if any, of (A) an amount equal to the present value of (1) the redemption price of such Note at November 1, 2022 plus (2) the
remaining scheduled interest payments on the Notes to be redeemed (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date) to November 1, 2022 (other than interest accrued to
the redemption date), computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of the Notes to be redeemed. The Trustee shall have no obligation to calculate or verify the
calculation of the Make Whole Amount. 
 “Treasury Rate” means, at the time of computation, the weekly
average for each business day during the most recent week that has ended at least two business days prior to the redemption date of the yield to maturity of United States Treasury securities with a constant maturity (as compiled and published in the
most recent Federal Reserve Statistical Release H.15 (or, if such statistical release is not so published or available or the relevant information no longer available thereon, any publicly available source of similar market data selected by the
Issuer in good faith) most nearly equal to the period from the redemption date to November 1, 2022; provided, however, that if the period from the redemption date to November 1, 2022 is not equal to the constant maturity of a United States
Treasury security for which a yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the yields of United States Treasury securities
for which such yields are given, except that if the period from the redemption date to November 1, 2022 is less than one year, the weekly average yield on actively traded United States Treasury securities adjusted to a constant maturity of one
year shall be used. 
 (d) In connection with any redemption of Notes described in clauses (a), (b) and (c) above, such
redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, including any related Equity Offering, issuance of Indebtedness or other transaction. If such redemption or notice is subject to satisfaction of one or
more conditions precedent, such notice shall state that, in the Issuer’s discretion, such redemption may not occur and such notice may be rescinded, or the redemption date may be delayed or extended, in the event that any or all such conditions
shall not have been satisfied by the redemption date. 
 (e) Notwithstanding the foregoing, in connection with any tender
offer for the Notes, including a Change of Control Offer, if holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer or Change of Control Offer and the
Issuer, or any third party making such tender offer or Change of Control Offer in lieu of the Issuer, purchases all of the Notes validly tendered and not withdrawn by such holders, the Issuer or such third party will have the right upon not less
than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase date, to redeem all Notes that remain outstanding following such purchase at a redemption price equal to the price offered to each other

 
holder (excluding any early tender or incentive fee) in such tender offer or Change of Control Offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if
any, thereon, to, but excluding, the date of such redemption. 
 (f) Tax Redemption. If (a) the Issuer or any
Guarantor becomes or will become obligated to pay Additional Amounts with respect to any Notes or any Guarantee (as described in Section 4.19 of the Indenture) as a result of (1) any change in, or amendment to, the laws, treaties
(including protocols), regulations or rulings of a Relevant Tax Jurisdiction, which change or amendment is first publicly announced and becomes effective after the Issue Date (or, if the Relevant Tax Jurisdiction did not become a Relevant Tax
Jurisdiction until a later date, after such later date) or (2) any change in the official interpretation or application of the laws, treaties (including protocols), regulations or rulings of a Relevant Tax Jurisdiction (including by virtue of a
holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which change is first publicly announced and becomes effective after the Issue Date (or, if the Relevant Tax Jurisdiction did not
become a Relevant Tax Jurisdiction until a later date, after such later date), and (b) such obligation cannot be avoided by the Issuer’s taking reasonable measures available to the Issuer or any Guarantor (provided that changing the
jurisdiction of the Issuer or any Guarantor is not a reasonable measure for this purpose), the Issuer may at its option, having given not less than 30 days’ notice to the holders of such Notes (which notice shall be irrevocable), redeem all,
but not a portion of, the Notes at any time a price equal to their principal amount plus interest accrued to, but excluding, the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the
relevant interest payment date), provided that no such notice of redemption shall be given earlier than 60 days prior to the earliest date on which the Issuer or any Guarantor would be obliged to pay such Additional Amounts were a payment in respect
of the Notes then due); and provided further that in the case of a Guarantor, no redemption shall be permitted under this section if the Issuer or any other Guarantor can make payments on the Notes without the obligation to pay Additional Amounts.
Prior to the publication or, where relevant, mailing of any notice of redemption pursuant to this paragraph, the Issuer shall deliver to the Trustee (i) a certificate of an officer of the Issuer stating that the requirements described in
clauses (a) and (b) above are satisfied, and (ii) an opinion of an independent counsel of recognized standing to the effect that the Issuer or any Guarantor has or will become obliged to pay such Additional Amounts as a result of a change
or amendment described in clause (a) above. The Trustee shall accept, and will be entitled to rely on, such certificate and opinion of counsel as sufficient evidence of the existence and satisfaction of the conditions described in clauses
(a) and (b) above, and upon such acceptance by the Trustee the Issuer will be entitled to give notice of redemption hereunder and such notice of redemption will be conclusive and binding on the holders of the Notes. 

(6) Repurchase at Option of Holder. Upon the occurrence of a Change of Control, the Issuer shall make an offer to each
Holder of Notes to repurchase on the Change of Control Payment Date all or any part of such Holder’s Notes (equal to $1,000 or an integral multiple thereof) at a purchase price equal to 101% of the aggregate principal amount thereof, together
with accrued and unpaid interest thereon to the date of repurchase (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). Holders of Notes that are subject to an offer to purchase
will receive a Change of Control Offer from the Issuer prior to any related Change of Control Payment Date and may elect to have such Notes purchased by completing the form entitled “Option of Holder To Elect Purchase” appearing below.

 When the cumulative amount of Excess Proceeds that have not been applied in accordance with Section 4.10 of the
Indenture exceeds $20.0 million, the Issuer shall make an offer to all Holders of the Notes (an “Excess Proceeds Offer”) to purchase the maximum principal amount of Notes that may be purchased out of such Excess
Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, together with accrued and unpaid interest to the date fixed for the closing of such offer in accordance with the procedures set forth in the Indenture. To
the extent the Issuer or a Restricted Subsidiary is required under the terms of other First Lien Obligations of the Issuer or such Restricted Subsidiary (other than Subordinated Indebtedness), the Issuer shall also make a pro rata offer to
the holders of such First Lien Obligations (including the Notes) with such proceeds. If the aggregate principal amount of Notes and other First Lien Obligations surrendered by holders thereof exceeds the amount of such Excess Proceeds, the Trustee
shall select the Notes to be purchased on a pro rata basis by lot, and, in the case of global notes, in accordance with the procedures of the Depositary. To the extent that the principal amount of Notes tendered pursuant to an Excess Proceeds
Offer is less than the amount of such Excess Proceeds, the Issuer may use any remaining Excess Proceeds in any manner not prohibited by the Indenture. Upon completion of an Excess Proceeds Offer, the amount of Excess Proceeds shall be reset at zero.
Holders of Notes that are subject to an 

 
offer to purchase will receive an Excess Proceeds Offer from the Issuer prior to any related Purchase Date and may elect to have such Notes purchased by completing the form entitled “Option
of Holder To Elect Purchase” appearing below. 
 (7) Notice of Redemption. Notice of redemption shall be
transmitted at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee). Notes may be redeemed in part but only in amounts of $2,000 or
whole multiples of $1,000 that are equal to or in excess of $2,000, unless all of the Notes held by a Holder of Notes are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption
unless the Issuer fails to redeem such Notes or such portions thereof. 
 (8) Suspension of Covenants. During any
period of time after the Issue Date that (i) the Notes are rated Investment Grade by both Rating Agencies and (ii) no Default or Event of Default has occurred and is continuing under the Indenture, the Issuer and its Restricted
Subsidiaries will not be subject to Sections 4.07 (Limitation on Restricted Payments), 4.09 (Limitation on Incurrence of Indebtedness), 4.10 (Limitation on Asset Sales), clause (d) of the first paragraph of Section 5.01 (Merger,
Consolidation or Sale of Assets), 4.11 (Limitation on Transactions with Affiliates), 4.08 (Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries) and 4.13 (Additional Subsidiary Guarantors). 

(9) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of
$2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder of a Note, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Neither the Issuer nor the Registrar is required to exchange or register the transfer of any Note or portion of a Note selected for
redemption. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 

(10) Persons Deemed Owners. Prior to due presentment to the Trustee for registration of the transfer of this Note, the
Trustee, any Agent and the Issuer may deem and treat the Person in whose name this Note is registered as its absolute owner for the purpose of receiving payment of principal of, premium, if any, and interest on this Note and for all other purposes
whatsoever, whether or not this Note is overdue, and neither the Trustee, any Agent nor the Issuer shall be affected by notice to the contrary. The registered Holder of a Note shall be treated as its owner for all purposes. 

(11) Amendments, Supplement and Waivers. Subject to certain exceptions, the Indenture, the Notes, the Collateral
Documents, the First Lien Intercreditor Agreement, any Junior Lien Intercreditor Agreement and the Guarantees or any amended or supplemental indenture may be amended or supplemented with the written consent of the Holders of at least a majority of
the aggregate principal amount of Notes then outstanding (including consents obtained in connection with an exchange offer or tender offer for the Notes), and any existing Default and its consequences or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a majority of the aggregate principal amount of Notes then outstanding (including consents obtained in connection with an exchange offer or tender offer for the Notes).
Notwithstanding the foregoing, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder of Notes) (a) reduce the principal
amount of Notes whose Holders must consent to an amendment, supplement or waiver; (b) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than as provided
in clause (h) below); (c) reduce the rate of or change the time for payment of interest on any Note; (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission
of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); (e) make any Note payable in money other than
that stated in the Notes; (f) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or interest on the Notes; (g) waive a redemption
payment or mandatory redemption with respect to any Note (other than as provided in clause (h) below); (h) amend, change or modify in any material respect the obligation of the Issuer to make and consummate a Change of Control Offer in the
event of a Change of Control after such Change of Control has occurred; (i) release all or substantially all of the Guarantees of the Guarantors other than in accordance with Article 10 of the Indenture; (j) make any change in the
foregoing amendment 

 
and waiver provisions; (k) impair the right to institute suit for the enforcement of any payment on or with respect to the Notes or the Guarantees; or (l) subordinate the payment of the
Notes or Guarantees to any other obligation of the Issuers or the Guarantors. Notwithstanding the foregoing, without the consent of any Holder of a Note, the Indenture, the Notes, the Guarantees, the Collateral Documents or any amended or
supplemental indenture may be amended or supplemented: to cure any ambiguity, defect or inconsistency (as determined by the Issuer in good faith); to provide for uncertificated Notes or Guarantees in addition to or in place of certificated Notes or
Guarantees; to provide for the assumption of the obligations of the Issuer or any Guarantor to the Holders of the Notes in the case of a merger, amalgamation, arrangement or consolidation pursuant to Article 5 or Article 10 of the Indenture; to make
any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the rights under the Indenture of any Holder of the Notes in any material respect; to provide for the issuance of
additional Notes in accordance with the provisions set forth in the Indenture; to evidence and provide for the acceptance of an appointment of a successor Trustee; to comply with the rules of any applicable securities depository; to add Guarantees

having substantially similar terms with respect to the holders of the Notes as those set forth in the First Lien Intercreditor Agreement, or any joinder thereto, or to enter into any Junior Lien Intercreditor Agreement in connection with the
incurrence of any Future First Lien Obligations or Junior Lien Obligations not otherwise prohibited by the Indenture; or with respect to the Collateral Documents and the First Lien Intercreditor Agreement, as provided in the relevant Collateral
Document or First Lien Intercreditor Agreement. 
 Notwithstanding the foregoing, without the consent of holders of at least
66 2/3% in aggregate principal amount of the Notes then outstanding, no amendment or waiver may (i) release all or substantially all of the Collateral from the Liens securing the Notes Obligations created by the Collateral Documents,
(ii) change or alter the priority of the Liens securing the Notes Obligations created by the Collateral Documents in any manner adverse to the holders of the Notes, or (iii) make any change in the First Lien Intercreditor Agreement, Junior
Lien Intercreditor Agreement or in the provisions of the Indenture or any Collateral Document dealing with the application of proceeds of the Collateral that would materially adversely affect the Holders or alter the priority of the security
interests in the Collateral..

 (a) default for 30 days in the payment when due of interest or additional interest, if any, on the
Notes; 
 (b) default in payment when due of principal of or premium, if any, on the Notes at maturity, upon

Indenture; 
 (d) subject to Section 6.04 of the Indenture, default under any other provision of the

be secured or evidenced any Indebtedness for money borrowed (or commitments in respect of Indebtedness for borrowed money) by the Issuer and any of the Restricted Subsidiaries (or the payment of which is guaranteed by the Issuer and any of the
Restricted Subsidiaries), which default is caused by a failure to pay the principal of such Indebtedness at the final stated maturity thereof within the grace period provided in such Indebtedness (a “Payment Default”), and the
principal amount of any such Indebtedness (including the principal amount of commitments in respect of such Indebtedness), together 

 
with the principal amount of any other such Indebtedness (including the principal amount of commitments in respect of such Indebtedness) under which there has been a Payment Default, aggregates
$25.0 million or more; 
 (f) 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 (or commitments in respect of Indebtedness for borrowed money) by the Issuer and any of the Restricted Subsidiaries (or the payment of which is guaranteed by
the Issuer or any of its Restricted Subsidiaries), which default results in the acceleration of such Indebtedness (or termination of related commitments) prior to its express maturity not rescinded or cured within 30 days after such
acceleration (or termination of related commitments), and the principal amount of any such Indebtedness (including the principal amount of commitments in respect of such Indebtedness), together with the principal amount of any other such
Indebtedness (including the principal amount of commitments in respect of such Indebtedness) under which there has been a Payment Default or the maturity of which has been so accelerated (or commitments terminated) and remains undischarged after
such 30 day period, aggregates $25.0 million or more; 
 (g) failure by the Issuer and any of the
Restricted Subsidiaries to pay final judgments (other than any judgment as to which a reputable insurance company has accepted full liability) aggregating $25.0 million or more, which judgments are not stayed within 60 days after their
entry; 
 (h) any Guarantee of a Significant Subsidiary (or a group of Restricted Subsidiaries that, taken
together, as of the last Measurement Period, would constitute a Significant Subsidiary) shall be held in a judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any Guarantor that
qualifies as a Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary), or any person acting on behalf of any Guarantor that qualifies as a
Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary), shall deny or disaffirm its obligations under its Guarantee; 

(i) the Issuer or any Significant Subsidiary of the Issuer (or a group of Restricted Subsidiaries that, taken
together, as of the last Measurement Period, would constitute a Significant Subsidiary) pursuant to or within the meaning of Bankruptcy Law (i) commences a voluntary case or proceeding under Bankruptcy Law; (ii) consents to the entry of an
order for relief against it in an involuntary case or proceeding under Bankruptcy Law; (iii) consents to the appointment of a custodian, trustee, receiver, receiver and manager, monitor or interim receiver of it or for all or substantially all
of its property; or (iv) makes a general assignment for the benefit of its creditors; and 
 (j) a court
of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Issuer or any Significant Subsidiary (or a group of Restricted Subsidiaries that, taken together, as of the last Measurement
Period, would constitute a Significant Subsidiary) of the Issuer in an involuntary case or proceeding; (ii) appoints a custodian, trustee, receiver, receiver and manager, monitor or interim receiver of the Issuer or any Significant Subsidiary
(or a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary) of the Issuer or for all or substantially all of the property of the Issuer or any Significant Subsidiary (or
a group of Restricted Subsidiaries that, taken together, as of the last Measurement Period, would constitute a Significant Subsidiary) of the Issuer; or (iii) orders the liquidation of the Issuer or any Significant Subsidiary of the Issuer, and
the order or decree remains unstayed and in effect for 60 consecutive days. 
 (k) any Collateral Document
after delivery thereof shall for any reason cease (or shall be asserted in writing by the Issuer or any Guarantor to cease) to create a valid and perfected first-priority Lien to the extent required by the Collateral Documents (subject to no other
Liens other than Permitted Liens) on Collateral that is (i) purported to be covered thereby and (ii) comprises Property which, when taken together with all Property as to which such a Lien has so ceased to be effective, has a fair market
value in excess of $25.0 million (other than (x) in accordance with the terms of the Indenture or the terms of the First Lien Intercreditor Agreement or the Collateral Documents or (y) except to the extent that any such
cessa-

 
tion of the Liens results from the failure of the administrative agent under the Credit Facilities or the Applicable Authorized Representative, as the case may be, in each case, as bailee for the
Collateral Agent pursuant to the terms of the First Lien Intercreditor Agreement, to maintain possession of certificates actually delivered to it representing securities pledged under the Collateral Documents). 

If any Event of Default occurs and is continuing, the Trustee, by notice to the Issuer, or the Holders of at least 25% of the
aggregate principal amount then outstanding of the Notes, by written notice to the Issuer and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default specified in
paragraph (i) or (j) of Section 6.01 of the Indenture, all outstanding Notes shall become and shall be immediately due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that
withholding notice is in such Holders’ interest. 
 However, a Default under Section 6.01(c), Section 6.01(d)
or Section 6.01(g) of the Indenture will not constitute an Event of Default until the Trustee or the holders of at least 25% in principal amount of the outstanding Notes notify the Issuer of the Default and, with respect to Section 6.01(c)
or Section 6.01(g) of the Indenture, the Issuer does not cure such Default within the time specified in Section 6.01(c) or Section 6.01(g) of the Indenture after the occurrence of such Default; provided that a notice of Default
may not be given with respect to any action taken, and reported publicly or to holders, more than two years prior to such notice of Default. 

Any failure to perform under, or breach of, Section 4.03 of the Indenture shall not be a Default or an Event of Default
until the 121st day after the Issuer has received the notice referred to in clause (d) of Section 6.01 of the Indenture (at which point, unless cured or waived, such failure to perform or breach shall constitute an Event of Default).
Any failure to perform, or breach of any covenant or agreement pursuant to Section 4.03 of the Indenture, shall automatically cease to be outstanding and shall be deemed to be cured at such time as the Issuer furnishes or files the applicable
information or report. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written
notice to the Trustee may on behalf of all the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or
premium that has become due solely because of the acceleration) have been cured or waived. The Holders of a majority in aggregate principal amount of the then outstanding Notes, by written notice to the Trustee, may on behalf of the Holders of all
of the Notes waive any existing Default or Event of Default and its consequences under the Indenture, except a continuing Default or Event of Default in the payment of interest or premium on, or principal of, the Notes. 

The Issuer is required to deliver to the Trustee annually a statement regarding compliance with the Indenture. 

(13) Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledges of the Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights if would have had if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the Commission for permission to continue as Trustee (if any of the Notes are registered pursuant to the Securities Act), or resign. 

(14) No Personal Liability of Directors, Owners, Employees, Incorporators and Stockholders. No director, owner, officer,
employee, incorporator or stockholder of the Issuer, the Guarantors or any of their Affiliates, as such, shall have any liability for any obligations of the Issuer, the Guarantors or any of their Affiliates under this Note, the Guarantees or the
Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. 
 (15) Guarantees. Payment of principal and interest (including interest on overdue principal
and overdue interest, if lawful) is unconditionally guaranteed, jointly and severally, by each of the Guarantors. 

 (16) Authentication. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent. 
 (17) Abbreviations. Customary abbreviations may
be used in the name of a Holder of a Note or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act). 
 (18) CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on
Uniform Note Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders of Notes. No representation is made as to
the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed herein. 

The Issuer will furnish to any Holder of a Note upon written request and without charge a copy of the Indenture. Requests may
