 Exhibit 10.10 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is made and entered into as of [____________, 202_], by and between Adit
EdTech Acquisition Corp., a Delaware corporation (the “Company”), and [____________] (“Indemnitee”). 

WHEREAS, the adoption of the Sarbanes-Oxley Act of 2002 and other laws, rules and regulations being promulgated have increased the
potential for liability of officers and directors; 
 WHEREAS, the Board of Directors of the Company (the “Board”)
has determined that the ability to attract and retain such persons is in the best interests of the Company’s stockholders; 

WHEREAS, it is reasonable, prudent and necessary for the Company to obligate itself contractually to indemnify such persons to the
fullest extent permitted by applicable law so that such persons will serve or continue to serve the Company free from undue concern that they will not be adequately indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of Article VII of the bylaws of the Company (the
“Bylaws”), and Article VIII of the Certificate of Incorporation of the Company and any resolutions adopted pursuant thereto and shall neither be deemed to be a substitute therefor nor to diminish or abrogate any rights of Indemnitee
thereunder; and 
 WHEREAS, Indemnitee is willing to serve on behalf of the Company on the condition that Indemnitee be indemnified
according to the terms of this Agreement. 
 NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the
Company and Indemnitee do hereby covenant and agree as follows: 
 1. Definitions. For purposes of this Agreement: 

1.1 “Change in Control” means a change in control of the Company occurring after the date hereof of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended (the “Act”),
whether or not the Company is then subject to such reporting requirement; provided, however, that, without limitation, such a Change in Control shall be deemed to have occurred if after the date hereof (i) any “person”
(as such term is used in Sections 13(d) and 14(d) of the Act), other than a person who is an officer or director of the Company on the date hereof (and any of such person’s affiliates), is or becomes “beneficial owner” (as defined in
Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing 50% or more of the combined voting power of the then outstanding securities of the Company without the prior
approval of at least two-thirds of the members of the Board in office immediately prior to such person attaining such percentage interest, (ii) the Company is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which (A) members of the Board in office immediately prior to such transaction or event constitute less than a majority of the Board thereafter or (B) the voting
securities of the Company outstanding immediately prior to such transaction do not continue to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 50% of the combined voting
power of the voting securities of the surviving entity outstanding immediately after such transaction with the power to elect at least a majority of the board of directors or other governing body of such surviving entity, or (iii) during any
period of two (2) consecutive years, individuals who at the beginning of such period constituted the Board (including for this purpose any new director whose election or nomination for election by the Company’s stockholders was approved by
a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any
reason to constitute at least a majority of the Board. 

 1.2 “Corporate Status” means the status of a person who is or was a
director, officer, employee, agent or fiduciary of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at the request of the Company. In addition,
service at the actual request of the Company, for purposes of this Agreement, Indemnitee shall be deemed to be serving or to have served at the request of the Company as a director, officer, employee, agent or fiduciary of any other enterprise if
Indemnitee is or was serving as a director, officer, employee, agent or fiduciary of such enterprise and (i) such enterprise is or at the time of such service was an affiliate of the Company, (ii) such enterprise is or at the time of such
service was an employee benefit plan (or related trust) sponsored or maintained by the Company or an affiliate of the Company, or (iii) the Company or an affiliate of the Company directly or indirectly caused Indemnitee to be nominated,
elected, appointed, designated, employed, engaged or selected to serve in such capacity. 
 1.3 “Disinterested Director”
means a director of the Company who is not and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee. 

1.4 “Expenses” means all reasonable attorneys’ fees, retainers, court costs (including trial and appeals), transcript
costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, federal, state, local, or foreign taxes imposed as a result of the actual or deemed receipt of
any payments under this Agreement, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, appealing, preparing to appeal, investigating, or being or
preparing to be a witness in a Proceeding. 
 1.5 “Independent Counsel” means a law firm, or a member of a law firm, that is
experienced in matters of corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any other matter material to either such party or (ii) any other
party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” does not include any person who, under the applicable standards of professional conduct then
prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. Except as provided in the first sentence of Section 9.3
hereof, Independent Counsel shall be selected by (i) the Disinterested Directors, (ii) a committee of the Board consisting of two (2) or more Disinterested Directors, or if (i) and (ii) above are not possible, then by a majority
of the full Board. 
 1.6 “Proceeding” means any action, suit, arbitration, alternate dispute resolution mechanism,
investigation, administrative hearing or any other proceeding, whether conducted by or on behalf of the Company or any other party, whether civil, criminal, administrative or investigative, except one initiated by an Indemnitee pursuant to
Section 11 of this Agreement to enforce Indemnitee’s rights under this Agreement. 
 2. Services by Indemnitee.
Indemnitee agrees to serve as a director, officer or employee of the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law). 

3. Indemnification—General. The Company shall indemnify, and, subject to Section 26 hereof, advance Expenses to,
Indemnitee as provided in this Agreement to the fullest extent permitted by applicable law in effect on the date hereof and to such greater extent as any amendment to or interpretation of applicable law may thereafter from time to time permit. The
rights of Indemnitee provided under the preceding sentence shall include, but shall not be limited to, the rights set forth in the other Sections of this Agreement. 

  
 2 

 4. Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled
to the rights of indemnification provided in this Agreement if, by reason of Indemnitee’s Corporate Status, Indemnitee is, was or is threatened to be made, a party to any threatened, pending or completed Proceeding, other than a Proceeding by
or in the right of the Company. Pursuant to this Agreement, subject to Section 26 hereof, Indemnitee shall be indemnified against Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably
incurred by Indemnitee or on behalf of Indemnitee in connection with any such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal Proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. 
 5.
Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Agreement if, by reason of Indemnitee’s Corporate Status, Indemnitee was or is threatened to be made, a party
to any threatened, pending or completed Proceeding brought by or in the right of the Company to procure a judgment in its favor. Pursuant to this Agreement, subject to Section 26 hereof, Indemnitee shall be indemnified
against amounts paid in settlement and Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with the defense or settlement of any such Proceeding if Indemnitee acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Notwithstanding the foregoing, no indemnification under this Section shall be made in respect of (i) a threatened or pending Proceeding which is
settled or otherwise disposed of or (ii) any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company, unless and only to the extent that the court in which such Proceeding shall have been brought, was
brought or is pending, shall determine, upon application, that Indemnitee is fairly and reasonably entitled to indemnity for such portion of the settlement amount and Expenses as the court deems proper. 

6. Indemnification for Expenses of Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement except for
Section 26 hereof, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be indemnified against all
Expenses (and, when eligible hereunder, amounts paid in settlement) actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on
the merits or otherwise, as to one (1) or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses (and, when eligible hereunder, amount paid in settlement) actually and
reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with each successfully resolved claim, issue or matter. For purposes of this Agreement, the term “successful, on the merits or otherwise,” includes, but is not
limited to, (i) any termination, withdrawal, or dismissal (with or without prejudice) of any Proceeding against Indemnitee without any express finding of liability or guilt against Indemnitee and (ii) the expiration of ninety
(90) days after the making of any claim or threat of a Proceeding without the institution of the same and without any promise or payment made to induce a settlement. 

7. Indemnification for Expenses as a Witness. Notwithstanding any other provision of this Agreement except for Section 26
hereof, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in
connection therewith.

 8. Advancement of Expenses and Other Amounts. Subject to Section 26 hereof,
the Company shall advance all Expenses, judgments, penalties, fines and, when eligible hereunder, amounts paid in settlement, incurred by or on behalf of Indemnitee in connection with any Proceeding within thirty (30) days after the receipt by
the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses,
judgments, penalties, fines and amounts paid in settlement, incurred by Indemnitee and shall include or be preceded or accompanied by an agreement by or on behalf of Indemnitee to repay any Expenses, judgments, penalties, fines and amounts paid in
settlement advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses, judgments, penalties, fines and, when eligible hereunder, amounts paid in settlement. In connection with any request
for advancement of Expenses, judgments, penalties, fines and amounts paid in settlement, Indemnitee shall not be required to provide any documentation or information to the extent that the provision thereof would undermine or otherwise jeopardize
attorney-client privilege. The Company’s obligation in respect of the advancement of Expenses, judgments, penalties, fines and amounts paid in settlement in connection with a criminal Proceeding in which Indemnitee is a defendant shall
terminate at such time as Indemnitee pleads guilty or is convicted after trial and such conviction becomes final and no longer subject to appeal. Advances shall be unsecured and interest free. Advances shall be made without regard to
Indemnitee’s ability to repay such amounts and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. 

9. Procedure for Determination of Entitlement to Indemnification. 

9.1 To obtain indemnification under this Agreement in connection with any Proceeding, and for the duration thereof, Indemnitee shall submit to
the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification.
The Secretary of the Company shall, promptly upon receipt of any such request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 

9.2 Upon written request by Indemnitee for indemnification pursuant to Section 9.1 hereof, a determination, if
required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in such case: (i) if a Change in Control shall have occurred, by Independent Counsel (unless Indemnitee shall request that such determination be
made by the Board or the stockholders, in which case in the manner provided for in clauses (ii) or (iii) of this Section 9.2) in a written opinion to the Board, a copy of which shall be delivered to Indemnitee,
(ii) if a Change in Control shall not have occurred, at the election of the Company, (A) by the Board by a majority vote of a quorum consisting of Disinterested Directors, (B) if a quorum of the Board consisting of Disinterested
Directors is not obtainable, by a majority of a committee of the Board consisting of two (2) or more Disinterested Directors, (C) by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee,
or (D) by the stockholders of the Company, by a majority vote of a quorum consisting of stockholders who are not parties to the proceeding, or if no such quorum is obtainable, by a majority vote of stockholders who are not parties to such
proceeding, or (iii) as provided in Section 10.2 of this Agreement. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such
determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance
request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’
fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification)
and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

 9.3 If a Change in Control shall have occurred, Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the Board), and Indemnitee (or the Board, as the case may be) shall give written notice to the other party advising it of the identity of Independent Counsel so selected. In
either event, Indemnitee or the Company, as the case may be, may, within seven (7) days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such
selection. Such objection may be asserted only on the ground that Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 1 of this Agreement, and the
objection shall set forth with particularity the factual basis of such assertion. If such written objection is made, Independent Counsel so selected may not serve as Independent Counsel unless and until a court has determined that such objection is
without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to Section 9.1 hereof, no Independent Counsel shall have been selected and not objected to,
either the Company or Indemnitee may petition a court of competent jurisdiction, for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment
as Independent Counsel of a person selected by such court or by such other person as such court shall designate, and the person with respect to whom an objection is so resolved or the person so appointed shall act as Independent Counsel under
Section 9.2 hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with its actions pursuant to this Agreement, and the Company shall
pay all reasonable fees and expenses incident to the procedures of this Section 9.3, regardless of the manner in which such Independent Counsel was selected or appointed. Upon the due commencement date of any judicial
proceeding pursuant to Section 11.1(iii) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct
then prevailing). 
 10. Presumptions and Effects of Certain Proceedings. 

10.1 In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 9.1 of this Agreement, and the Company
shall have the burden of proof to overcome that presumption by clear and convincing evidence in connection with the making by any person, persons or entity of any determination contrary to that presumption. 

10.2 If the person, persons or entity empowered or selected under Section 9 of this Agreement to determine whether
Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have
been made and Indemnitee shall be entitled to such indemnification, absent (i)a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection
with the request for indemnification or (ii) prohibition of such indemnification under applicable law; provided, however, that such sixty (60) day period may be extended for a reasonable time, not to exceed an additional
thirty (30) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in good faith require(s) such additional time for the obtaining or evaluating of documentation and/or information
relating thereto; and provided, further, however, that the foregoing provisions of this Section 10.2 shall not apply (x) if the determination of entitlement to indemnification is to be made by the
stockholders pursuant to Section 9.2 of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board has resolved to submit such determination to
the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat or (B) a special meeting of stockholders is called within fifteen
(15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and 

  
 5 

 
such determination is made thereat or (y) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 9.2 of
this Agreement. In connection with each meeting at which a stockholder determination will be made, the Company shall solicit proxies that expressly include a proposal to indemnify or reimburse Indemnitee. The Company shall afford Indemnitee ample
opportunity to present evidence of the facts upon which Indemnitee relies for indemnification in any Company proxy statement relating to such stockholder determination. Subject to the fiduciary duties of its members under applicable law, the Board
will not recommend against indemnification or reimbursement in any proxy statement relating to the proposal to indemnify or reimburse Indemnitee. 

10.3 The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea
of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in
a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 

10.4 Reliance as Safe Harbor. For purposes of this Agreement, Indemnitee shall be deemed to have acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal Proceeding, to have had no reasonable cause to believe Indemnitee’s conduct was unlawful, if Indemnitee’s action
is based on (i) the records or books of account of the Company, or another enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Company or another enterprise in the course of their
duties, (iii) the advice of legal counsel for the Company or another enterprise, (iv) or of an independent certified public accountant or an appraiser or other expert selected with reasonable care by the Company or another enterprise. The
term “another enterprise” as used in this Section shall mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the
Company as a director, officer, partner, trustee, employee or agent. The provisions of this Section shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable
standard of conduct set forth herein. Whether or not the foregoing provisions of this Section 10.4 are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal Proceeding, to have had no reasonable cause to believe Indemnitee’s conduct was unlawful. Anyone seeking to overcome
this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 11. Remedies of Indemnitee. 

11.1 In the event that (i) a determination is made pursuant to Section 9 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 of this Agreement, (iii) the determination of indemnification is to be made by
Independent Counsel pursuant to Section 9.2 of this Agreement and such determination shall not have been made and delivered in a written opinion within sixty (60) days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to Section 7 of this Agreement within thirty (30) days after receipt by the Company of a written request therefor, or (v) payment of
indemnification is not made within thirty (30) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 9 or
Section 10 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of New York, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such
indemnification or advancement of Expenses, judgments, penalties, fines or, when eligible hereunder, amounts paid in settlement. The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

  
 6 

 11.2 In the event that a determination shall have been made pursuant to
Section 9 of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section shall be conducted in all respects as a de novo trial on the merits and Indemnitee
shall not be prejudiced by reason of that adverse determination. 
 11.3 If a determination shall have been made or deemed to have been made
pursuant to Section 9 or Section 10 of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant
to this Section, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification or
(ii) prohibition of such indemnification under applicable law. 
 11.4 The Company shall be precluded from asserting in any judicial
proceeding commenced pursuant to this Section that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. 

11.5 In the event that Indemnitee, pursuant to this Section, seeks a judicial adjudication of Indemnitee’s rights under, or to recover
damages for breach of, this Agreement or any other agreement, including any other indemnification, contribution or advancement agreement, or any provision of the certificate of incorporation or the Bylaws now or hereafter in effect, or for recovery
under directors’ and officers’ liability insurance policies maintained by the Company, Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all expenses (of the kinds described
in the definition of Expenses) actually and reasonably incurred by Indemnitee in such judicial adjudication, but only if Indemnitee prevails therein. If it shall be determined in such judicial adjudication that Indemnitee is entitled to receive less
than all of the indemnification or advancement of expenses sought, the expenses incurred by Indemnitee in connection with such judicial adjudication shall be appropriately prorated. In addition, the Company shall, if so requested by Indemnitee,
advance the foregoing expenses to Indemnitee, subject to and in accordance with Section 8. 
 12. Procedure Regarding
Indemnification. With respect to any Proceedings, Indemnitee, prior to taking any action with respect to such Proceeding, shall consult with the Company as to the procedure to be followed in defending, settling, or compromising the Proceeding
and may not consent to any settlement or compromise of the Proceeding without the written consent of the Company (which consent may not be unreasonably withheld or delayed). The Company shall be entitled to participate in defending, settling or
compromising any Proceeding and to assume the defense of such Proceeding with counsel of its choice and shall assume such defense if requested by Indemnitee. Notwithstanding the election by, or obligation of, the Company to assume the defense of a
Proceeding, Indemnitee shall have the right to participate in the defense of such Proceeding and to employ counsel of Indemnitee’s choice, but the fees and expenses of such counsel shall be at the expense of Indemnitee unless (i) the
employment of such counsel has been authorized in writing by the Company or (ii) Indemnitee has reasonably concluded that there may be defenses available to Indemnitee which are different from or additional to those available to the Company (in
which latter case the Company shall not have the right to direct the defense of such Proceeding on behalf of Indemnitee), in either of which events the fees and expenses of not more than one (1) additional firm of attorneys selected by
Indemnitee shall be borne by the Company. If the Company assumes the defense of a Proceeding, then counsel for the Company and Indemnitee shall keep Indemnitee reasonably informed of the status of the Proceeding and promptly send to Indemnitee
copies of all documents filed or produced in the Proceeding, and the Company shall not compromise or settle any such Proceeding without the written consent of Indemnitee (which consent may not be unreasonably withheld or delayed) if the relief
provided shall be other than monetary damages and shall promptly notify Indemnitee of any settlement and the amount thereof. 

  
 7 

 13. Non-Exclusivity; Survival of Rights; Insurance; Subrogation;
Contribution. 
 13.1 The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be
deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the certificate of incorporation or the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No
amendment, alteration or repeal of this Agreement or any provision hereof shall be effective as to any Indemnitee with respect to any action taken or omitted by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment,
alteration or repeal. 
 13.2 To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, officers, employees, agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of the Company, Indemnitee shall
be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee, agent or fiduciary under such policy or policies. 

13.3 In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are reasonably necessary to enable the Company to bring suit to enforce such rights. 

13.4 The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent
that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 
 13.5 If a
determination is made that Indemnitee is not entitled to indemnification, after Indemnitee submits a written request therefor, under this Agreement, then in respect of any threatened, pending or completed Proceeding in which the Company is jointly
liability with Indemnitee (or would be if joined in such Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement by Indemnitee in such proportion as is appropriate to reflect (i) the
relative benefits received by the Company on the one hand and Indemnitee on the other hand from the transaction from which Proceeding arose and (ii) the relative fault of the Company on the one hand and of Indemnitee on the other hand in
connection with the events that resulted in such Expenses, judgments, fines or amounts paid in settlement, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of Indemnitee on the other hand
shall be determined by reference to, among other things, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent the circumstances resulting in such Expenses, judgments, fines or amounts paid in
settlement. The Company agrees that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation or any other method of allocation that does not take into account the foregoing equitable
considerations. The determination as to the amount of the contribution, if any, shall be made by: (x) a court of competent jurisdiction upon the application of both Indemnitee and the Company (if the Proceeding had been brought in, and final
determination had been rendered by such court), (y) the Board by a majority vote of a quorum consisting of Disinterested Directors, or (z) Independent Counsel, if a quorum is not obtainable for purpose of (y) above, or, even if
obtainable, a quorum of Disinterested Directors so directs. 

  
 8 

 14. Duration of Agreement. This Agreement shall continue until and terminate upon the later of:
(i) ten (10) years after the date that Indemnitee shall have ceased to serve as a director and/or officer of the Company or (ii) the final termination of all pending Proceedings in respect of which Indemnitee is granted rights of
indemnification or advancement of Expenses, judgments, penalties, fines or amounts paid in settlement hereunder and or any proceeding commenced by Indemnitee pursuant to Section 11 of this Agreement. This Agreement shall be
binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s spouse, heirs, executors, personal representatives and administrators. The Company shall require and cause any successor
(whether direct or indirect by purchase, merger, consolidation, or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee,
expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

15. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (ii) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of
any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable. 
 16. Entire Agreement. This Agreement constitutes the entire agreement between the Company and Indemnitee with

For purposes of determining compliance with
this definition, (A) a Lien need not be incurred solely by reference to one category of Permitted Liens described in this definition
but is permitted to be incurred in part under any combination thereof and of any other available exemption, (B) in the event that
a Lien (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens, the Issuer will, in its
sole discretion, be entitled to divide, classify or reclassify, in whole or in part, any such Lien (or any portion thereof) among
one or more such categories or clauses in any manner that complies with this definition and (C) in the event that a portion of
Indebtedness secured by a Lien could be classified as secured in part pursuant to clause (1)(ii) above (giving pro forma
effect only to the incurrence of such portion of such Indebtedness), the Issuer, in its sole discretion, may classify such portion
of such Indebtedness (and any obligations in respect thereof) as having been secured pursuant to clause (1)(ii) above and thereafter
the remainder of the Indebtedness as having been secured pursuant to one or more of the other clauses of this definition.

 

In addition, (i) the outstanding principal
amount of any particular Indebtedness shall be counted only once, and any obligations arising under any guarantee, Lien, letter
of credit or similar instrument supporting such Indebtedness shall not be double counted; (ii) for purposes of determining compliance
with any Canadian dollar or other currency denominated restriction on the incurrence of Indebtedness, the Canadian dollar or other
currency-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant
currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed
or first incurred (whichever yields the lower Canadian dollar or other currency-equivalent), in the case of revolving credit borrowings.
However, if the Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and the refinancing
would cause the applicable Canadian dollar or other currency denominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such Canadian dollar or other currency denominated restriction
shall be deemed not to have been exceeded so long as the principal amount of the refinancing Indebtedness does not exceed the principal
amount of the Indebtedness being refinanced (except to the extent necessary to pay all fees, defeasance costs, expenses and premiums
(including tender premiums) incurred in connection therewith); and (iii) notwithstanding any other provision of this definition,
the maximum amount of Indebtedness that the Issuer and its Restricted Subsidiaries may secure pursuant to this definition shall
not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange
rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different
currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies
in which the respective Indebtedness is denominated that is in effect on the date of such refinancing.

 

In the event that the Issuer or a Restricted
Subsidiary enters into or increases commitments under a revolving credit facility secured under clause (1) of this definition,
the Secured Net Leverage Ratio for borrowings and reborrowings thereunder (and including letters of guarantee, tender checks and
letters of credit thereunder) may be determined, at the election of the Issuer, on the date of such revolving credit facility or
on the date of such increase in commitments (assuming that the full amount thereof has been borrowed as of such date), and, if
the Secured Net Leverage Ratio test is satisfied with respect thereto at such time, any borrowing or reborrowing thereunder (and
including letters of guarantee, tender checks and letters of credit thereunder) will be permitted to be secured irrespective of
the Secured Net Leverage Ratio at the time of any borrowing or reborrowing (or and including letters of guarantee, tender checks
or letters of credit thereunder) (the committed amount permitted to be borrowed or reborrowed (and the issuance and creation of
letters of credit and bankers’ acceptances) on a date pursuant to the operation of this paragraph shall be the “Reserved
Indebtedness Amount” as of such date for purposes of the Secured Net Leverage Ratio).

Issuer or a Guarantor, that is customary in the relevant local market); provided that with respect to Permitted Receivables
Financings incurred in the form of a factoring program under this clause (ii), the outstanding amount of such Permitted Receivables

most recently completed four consecutive fiscal quarters of the Issuer for which internal financial statements are available),

with the terms of such Permitted Receivables Financing (but excluding any such collections used to make payments of commissions,

discharged or refunded;

replaced, defeased, discharged or refunded (including any after-acquired property to the extent it would have been subject to the
original Lien, plus improvements and accessions to, such property or proceeds or distributions thereof); and

		(1)	in the event that the Issuer or any of its Restricted Subsidiaries incurs, assumes, guarantees, repays, repurchases, redeems,
defeases or otherwise discharges any Indebtedness (other than ordinary working capital borrowings and borrowings pursuant to the
First Lien Revolving Credit Agreement) or issues, repurchases or redeems Disqualified Stock or preferred stock subsequent to the
commencement of the period for which the Secured Net Leverage Ratio is being calculated and on or prior to the date on which the
event for which the calculation of the Secured Net Leverage Ratio is made (the “Calculation Date”), then the
Secured Net Leverage Ratio will be calculated giving pro forma effect to such incurrence, assumption, guarantee, repayment,
repurchase, redemption, defeasance or other discharge of Indebtedness, or such issuance, repurchase or redemption of Disqualified
Stock or preferred stock, and the use of the proceeds therefrom, as if the same had occurred at the beginning of the applicable
four-quarter reference period;

 

		(2)	(A) acquisitions and Investments that have been made, customer contracts that have been entered into, by the Issuer or any
of its Restricted Subsidiaries, including through mergers or consolidations, or any Person or any of its Restricted Subsidiaries
acquired by the Issuer or any of its Restricted Subsidiaries, and including any related financing transactions and including increases
in ownership of Restricted Subsidiaries, during the four-quarter reference period or subsequent to such reference period and on
or prior to the Calculation Date, will be given pro forma effect as if they had occurred on the first day of the four-quarter
reference period, and (B) Consolidated EBITDA for such reference period shall be calculated on a pro forma basis giving
effect to (i) any expense and cost reductions and other synergies related to such transaction referred to in clause (2)(A) above
and (ii) any other expense reductions and cost savings related to operational efficiencies, strategic initiatives or purchasing
improvements and other synergies (whether or not related to such transactions referred to in clause (2)(A) above), in each case
that have occurred prior to the Calculation Date or are reasonably expected to occur within 24 months of the Calculation Date,
in the reasonable judgment of the chief financial or accounting officer of the Issuer in good faith (regardless of whether those
cost savings or operating improvements could then be reflected in pro forma financial statements in accordance with Regulation
S-X promulgated under the 1933 Act or any other regulation or policy of the Commission related thereto); provided that such
net cost savings, initiatives, improvements and synergies are reasonably identifiable and quantifiable;

 

    51

     

    

 

		(3)	the Consolidated EBITDA attributable to discontinued operations, as determined in accordance with GAAP, and operations or businesses
(and ownership interests therein) disposed of prior to the Calculation Date, will be excluded;

 

		(4)	the Fixed Charges attributable to discontinued operations, as determined in accordance with GAAP, and operations or businesses
(and ownership interests therein) disposed of prior to the Calculation Date, will be excluded, but only to the extent that the
obligations giving rise to such Fixed Charges will not be obligations of the specified Person or any of its Restricted Subsidiaries
following the Calculation Date;

 

		(5)	any Person that is a Restricted Subsidiary on the Calculation Date will be deemed to have been a Restricted Subsidiary at all
times during such four-quarter reference period;

 

		(6)	any Person that is not a Restricted Subsidiary on the Calculation Date will be deemed not to have been a Restricted Subsidiary
at any time during such four-quarter period;

 

		(7)	if the Issuer so elects, pro forma effect shall be given to any entity, division, plant, unit or line of business or
New Project that commenced and completed at least one full fiscal quarter of operations during such reference period as if such
entity, division, plant, unit, line of business or New Project had commenced commercial operations on the first day of such reference
period and such pro forma calculation shall be based on the annualized results of commercial operations of such entity,
plant, unit, division or line of business since the date it so commenced commercial operations;

 

    52

     

    

 

		(8)	if any Indebtedness bears a floating rate of interest, the interest expense on such Indebtedness will be calculated as if the
weighted average interest rate during such period had been the rate of interest in effect on the Calculation Date and had been
the applicable rate for the entire period (taking into account any Hedging Obligation applicable to such Indebtedness if such Hedging
Obligation has a remaining term as at the Calculation Date in excess of 12 months or ends on the maturity date of such Indebtedness);
and

 

		(9)	when calculating the availability under any basket or ratio under this Indenture, in each case in connection with a Limited
Condition Acquisition or Investment, the Calculation Date of such basket or ratio and determination as to whether any Default or
Event of Default shall have occurred and be continuing may, at the option of the Issuer (which election may be made on the date
of such acquisition), be the date the definitive agreements for such Limited Condition Acquisition or Investment are entered into
and, if the Issuer so elects, such baskets or ratios shall be calculated on a pro forma basis after giving effect to such
Limited Condition Acquisition or Investment and the other transactions to be entered into in connection therewith (including any
incurrence of Indebtedness and the use of proceeds thereof) as if they occurred at the beginning of the applicable reference period
for purposes of determining the ability to consummate any such Limited Condition Acquisition or Investment, and, for the avoidance
of doubt, (x) if any of such baskets or ratios are exceeded as a result of fluctuations in such basket or ratio (including due
to fluctuations in Consolidated EBITDA or Total Assets of the Issuer or the target company) subsequent to such Calculation Date
at or prior to the consummation of the relevant Limited Condition Acquisition or Investment, such baskets or ratios will not be
deemed to have been exceeded as a result of such fluctuations and (y) such baskets or ratios need not be tested at the time of
consummation of such Limited Condition Acquisition or Investment or related transactions; provided, however, that
(a) if any ratios improve or baskets increase as a result of such fluctuations, such improved ratios or baskets may be utilized
and (b) if the Issuer elects to have such Calculation Date and determination occur at the time of entry into such definitive agreement,
any such transactions (including any incurrence of Indebtedness and the use of proceeds thereof) shall be deemed to have occurred
on the date the definitive agreements are entered into and outstanding thereafter for purposes of calculating any baskets or ratios
under this Indenture after the date of such agreement and before the consummation of such Limited Condition Acquisition or Investment
and unless and until such Limited Condition Acquisition has been abandoned, as determined by the Issuer, prior to the consummation
thereof. For the avoidance of doubt, if the Issuer has exercised its option pursuant to the foregoing and any Default or Event
of Default occurs following the date on which the definitive acquisition agreements for the applicable Limited Condition Acquisition
were entered into and prior to or on the date of the consummation of such Limited Condition Acquisition, any such Default or Event
of Default shall be deemed to not have occurred or be continuing for purposes of determining whether any action being taken in
connection with such Limited Condition Acquisition is permitted under this Indenture.

(including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached
thereto). The Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without
the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto).
Each Global Note shall represent the amount of outstanding Notes specified therein, and each Global Note shall provide that it
shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect
exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate
principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Notes Custodian of the Issuer, at
the direction of the Trustee, in accordance with the instructions given by the Holder thereof as required by Section 2.6 hereof.

 

(c)                    
Regulation S Global Notes. Any Notes offered and sold in reliance on Regulation S shall be issued initially in the
form of a Regulation S Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with
the Notes Custodian, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated
agents holding on behalf of Euroclear or Clearstream, duly executed by the Issuer and authenticated by the Trustee as hereinafter
provided. Prior to the expiration of the Restricted Period, any resale or transfer of beneficial interests in a Regulation S Global
Note to U.S. Persons shall not be permitted unless such resale or transfer is made pursuant to Rule 144A or Regulation S.

 

(d)                    
144A Global Notes. Any Notes offered and sold in reliance on Rule 144A shall be issued initially in the form of
a 144A Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Notes Custodian,
and registered in the name of the Depositary or the nominee of the Depositary, duly executed by the Issuer and authenticated by
the Trustee as hereinafter provided.

 

(e)                    
Definitive Notes. Notwithstanding any other provision of this Section 2.1, any issuance of Definitive Notes shall
be at the Issuer’s discretion, except in the circumstances set forth in Section 2.6(a) hereof.

 

Section 2.2.      Execution and Authentication.

 

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

 

    61

     

    

 

 

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

 

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

 

The Trustee shall authenticate and deliver:
(i) Initial Notes for original issue in an aggregate principal amount of US$750,000,000 on the Issue Date, and (ii) if and when
issued, Additional Notes (which may be issued in either a registered or a private offering under the 1933 Act), in each case upon
an Issuer Order. Such Issuer Order shall specify the amount of the Notes to be authenticated and the date on which the original
issue of Notes is to be authenticated and whether the Notes are to be in global or definitive form and whether they are to bear
the Private Placement Legend or the Canadian Legend. The Issuer may issue Additional Notes under this Indenture subsequent to the
Issue Date. For the avoidance of any doubt, any Additional Notes that are issued hereunder, and in connection therewith the Issuer
delivered to the Trustee an Officer’s Certificate and Opinion of Counsel each stating that such issuance of Additional Notes
is authorized and permitted under this Indenture, shall be valid for all purposes and constitute Additional Notes hereunder, even
if subsequently it is determined that such issuance was not in compliance with the covenants of this Indenture.

 

The Trustee may appoint an agent (the “Authenticating
Agent”) reasonably acceptable to the Issuer to authenticate the Notes. Unless limited by the terms of such appointment,
any such 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.

 

Section 2.3.         
Registrar and Paying Agent.

 

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

 

The Issuer or any of its Subsidiaries may
act as Paying Agent, subject to the provisions of this Section 2.3 and Section 4.10. Any Paying Agent or Registrar may resign as
such upon 30 days’ prior written notice to the Issuer and the Trustee; upon resignation of any Paying Agent or Registrar,
the Issuer shall appoint a successor Paying Agent or Registrar, as the case may be, complying with the requirements of this Section
2.3, no later than 30 days thereafter and shall provide notice to the Trustee of such successor Paying Agent or Registrar.

 

If at any time there shall be Notes outstanding
that are not Global Notes and there shall be no Paying Agent with an office or agency in the City of New York, State of New York
(or as such office may be moved from time to time to any other location within the contiguous U.S.), where the Notes may be presented
or surrendered for payment, the Issuer shall forthwith designate such a Paying Agent in order that such Notes shall at all times
be payable in the City of New York, the State of New York (or as such office may be moved from time to time to any other location
within the contiguous U.S.).

 

    62 

     

    

 

The Issuer initially appoints Computershare
Trust Company, N.A., as Registrar and Paying Agent for the Notes. The immunities, protections and exculpations available to the
Trustee under this Indenture shall also be available to each Agent, and the Issuer’s obligations under Section 7.6 to compensate
and indemnify the Trustee shall extend likewise to each Agent.

 

Section 2.4.         
Paying Agent to Hold Money in Trust.

 

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

 

Section 2.5.         
Holder Lists.

 

The Trustee shall preserve in as current
a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee
is not the Registrar, the Issuer shall furnish to the Trustee, in writing at least seven (7) Business Days before each Interest
Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee
may reasonably require of the names and addresses of Holders.

 

Section 2.6.         
Transfer and Exchange.

 

(a)                    
Transfer and Exchange of Global Notes. Except as set forth herein, 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.
Owners of beneficial interests in Global Notes shall not be entitled to receive Definitive Notes unless:

 

(1)           
the Depositary (A) notifies the Issuer that it is unwilling or unable to continue to act as Depositary or (B) that it is
no longer a clearing agency registered under the 1934 Act and, in either case, a successor Depositary is not appointed by the Issuer
within 90 days after the date of such notice from the Depositary;

 

    63 

     

    

 

(2)           
the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of the certificated Notes
and any Participant requests a certificated Note; provided that in no event shall the Regulation S Global Note be exchanged
by the Issuer for Definitive Notes prior to (a) the expiration of the Restricted Period and (b) the receipt of any certificates
required under the provisions of Regulation S;

 

(3)           
there has occurred and is continuing a Default or Event of Default with respect to the Notes and the Depositary notifies
the Issuer and the Trustee of its decision to exchange the Global Notes for Definitive Notes; or

 

(4)           
written notice is given to the Trustee by or on behalf of the Depositary in accordance with this Indenture.

 

Upon the occurrence of the preceding events
in clauses (1), (2), (3) or (4) above, Definitive Notes shall be issued in such names and in any approved denominations as the
Depositary shall instruct the Issuer, the Trustee and the Registrar. Global Notes also may be exchanged or replaced, in whole or
in part, as provided in Section 2.7 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note
or any portion thereof, pursuant to this Section 2.6 or Section 2.7 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 2.6(a);
however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.6(b) or (c).

 

(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 of this Indenture and the Applicable
Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those
set forth herein, including those set forth in the Private Placement Legend and the Canadian Legend (if applicable), to the extent
required by the 1933 Act and applicable Canadian Securities Legislation, and the U.S. transfers of beneficial interests in the
Global Notes also shall require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of
the other following provisions of this Section 2.6, as applicable:

 

(1)           
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, (A) transfers of beneficial interests in the Regulation S Global Note may not be to
a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser) and (B) such beneficial interests
may be held only through Euroclear or Clearstream (as Indirect Participants in the Depositary). Beneficial interests in such 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
the preceding sentence of this Section 2.6(b)(1).

 

    64 

     

    

 

(2)           
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 Section 2.6(b)(1) above, the transferor of such beneficial interest must deliver
to the Registrar either:

 

(A)            
(i)             
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

 

(ii)           
instructions given in accordance with the Applicable Procedures containing information regarding the Participant account
to be credited with such increase; or

 

(B)            
(i)             
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

 

(ii)           
instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive
Note shall be registered to effect the transfer or exchange referred to in Section 2.6(b) above; provided that in no event
shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Global Note prior to
(a) the expiration of the Restricted Period and (b) the receipt of any certificates required under the provisions of Regulation
S.

 

Upon satisfaction of all of the requirements
for transfer or exchange of beneficial interests in Global Notes contained in this Indenture, the Notes or otherwise applicable
under the 1933 Act, the principal amount of the relevant Global Note(s) shall be adjusted pursuant to Section 2.6(g) hereof.

 

(3)           
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 Section 2.6(b)(2) above and the Registrar receives the following:

 

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

 

    65 

     

    

 

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

 

(4)           
Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in the 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 Section 2.6(b)(2) above and the Registrar receives the
following:

 

(i)           
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 C hereto, including
the certifications in item (1)(a) thereof; or

 

(ii)           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 B hereto, including the certifications in item (4) thereof;

 

and, in each such case, if the Registrar or the Issuer so requests
or if the Applicable Procedures so require, an Opinion of Counsel to the effect that such exchange or transfer is in compliance
with the 1933 Act and state “blue sky” laws and that the restrictions on transfer contained herein and in the Private
Placement Legend are no longer required in order to maintain compliance with the 1933 Act.

 

If any such transfer is effected at a time
when an Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Issuer Order in accordance
with Section 2.2 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.

 

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.

 

    66 

     

    

 

(c)                    
Transfer or Exchange of Beneficial Interests for Definitive Notes.

 

(1)           
Beneficial Interests in Restricted Global Notes to Restricted Definitive Notes. If, in accordance with Section 2.6(a),
any holder of a beneficial interest in a Restricted Global Note proposes to exchange such beneficial interest for a Restricted
Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Restricted Definitive

(C)           
if such beneficial interest is being transferred to a non-U.S. Person in an offshore transaction in accordance with Rule
903 or Rule 904, a certificate to the effect set forth in Exhibit B hereto, including the certifications in item (2) thereof,

 

the Registrar shall cause the aggregate principal amount of
the applicable Global Note to be reduced accordingly pursuant to Section 2.6(g) hereof, and the Issuer shall execute and the Trustee,
upon receipt of an Issuer Order, shall authenticate and deliver to the Person designated in the instructions a Definitive Note
in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest in a Restricted Global Note
pursuant to this Section 2.6(c) shall be registered in such name or names and in such authorized denomination or denominations
as the holder of such beneficial interest shall instruct the Registrar through instructions from the Depositary and the Participant
or Indirect Participant. The Trustee shall deliver such Definitive Notes to the Persons in whose names such Notes are so registered.
Any Definitive Note issued in exchange for a beneficial interest in a Restricted Global Note pursuant to this Section 2.6(c)(1)
shall bear the Private Placement Legend and shall be subject to all restrictions on transfer contained therein. Notwithstanding
Sections 2.6(c)(1)(A) and (C) hereof, a beneficial interest in the Regulation S Global Note may not be exchanged for a Definitive
Note or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (a) the expiration of the
Restricted Period and (b) the receipt of any certificates required under the provisions of Regulation S, except in the case of
a transfer pursuant to an exemption from the registration requirements of the 1933 Act other than Rule 903 or Rule 904.

 

(2)           
Beneficial Interests in Restricted Global Notes to 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, in each case only pursuant to Section
2.6(a) and only if the Registrar receives the following:

 

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

 

    67

Person who shall take delivery thereof in the form of an Unrestricted Definitive Note, a certificate from such holder in the form
of Exhibit B hereto, including the certifications in item (4) thereof;

 

and, in each such case, if the Registrar or the Issuer so requests
or if the Applicable Procedures so require, an Opinion of Counsel to the effect that such exchange or transfer is in compliance
with the 1933 Act and state “blue sky” laws and that the restrictions on transfer contained herein and in the Private
Placement Legend are no longer required in order to maintain compliance with the 1933 Act.

 

(3)           
Beneficial Interests in Unrestricted Global Notes to Unrestricted Definitive Notes. If any holder of a beneficial
interest in an Unrestricted Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such
beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions
set forth in Section 2.6(b)(2) hereof, the Registrar shall cause the aggregate principal amount of the applicable Global Note to
be reduced accordingly pursuant to Section 2.6(g) hereof, and the Issuer shall execute and the Trustee, upon receipt of an Issuer
Order, shall authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal
amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.6(c)(3) shall be registered
in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest shall instruct
the Registrar through instructions from the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such
Definitive Notes to the Persons in whose names such Notes are so registered. Any Definitive Note issued in exchange for a beneficial
interest pursuant to this Section 2.6(c)(3) shall not bear the Private Placement Legend.

 

(d)                    
Transfer and Exchange of Definitive Notes for Beneficial Interests.

 

(1)           
Restricted Definitive Notes to Beneficial Interests in Restricted Global Notes. If any Holder of a Restricted Definitive
Note proposes to exchange such Note for a beneficial interest in a Restricted Global Note or to transfer such Restricted Definitive
Note to a Person who takes delivery thereof in the form of a beneficial interest in a Restricted Global Note, then, upon receipt
by the Registrar of the following documentation:

appropriate Restricted Global Note, in the case of clause (d)(1)(B) above, the 144A Global Note, and in the case of clause (d)(1)(C)
above, the Regulation S Global Note. Notwithstanding the foregoing, if there are no Global Notes outstanding prior to any such
transfer, Definitive Notes may be transferred for beneficial interests in a Global Note only if the Issuer so agrees and delivers
an Issuer Order to the Trustee.

 

(2)           
Restricted Definitive Notes to Beneficial Interests in Unrestricted Global Notes. A Holder of a Restricted Definitive
Note may exchange such Note for a beneficial interest in an Unrestricted Global Note or transfer such Restricted Definitive Note
to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note only if the Registrar

(i)           
if the Holder of such Definitive Notes proposes to exchange such Notes for a beneficial interest in the Unrestricted Global
Note, a certificate from such Holder in the form of Exhibit C hereto, including the certifications in item (1)(c) thereof;
or

 

(ii)          
if the Holder of such Definitive Notes proposes to transfer such Notes to a Person who shall take delivery thereof in the
form of a beneficial interest in the Unrestricted Global Note, a certificate from such Holder in the form of Exhibit B hereto,
including the certifications in item (4) thereof;

 

and, in each such case, if the Registrar or the Issuer so requests

Placement Legend are no longer required in order to maintain compliance with the 1933 Act.

 

Upon satisfaction of the conditions of any
of the subparagraphs in this Section 2.6(d)(2), the Trustee shall cancel the Definitive Notes and the Registrar shall increase
or cause to be increased the aggregate principal amount of the Unrestricted Global Note. Notwithstanding the foregoing, if there
are no Global Notes outstanding prior to any such transfer, Definitive Notes may be transferred for beneficial interests in a Global
Note only if the Issuer so agrees and delivers an Issuer Order to the Trustee.

 

(3)           
Unrestricted Definitive Notes to Beneficial Interests in Unrestricted Global Notes. A Holder of an Unrestricted Definitive
Note may exchange such Note for a beneficial interest in an Unrestricted Global Note or transfer such Definitive Note to a Person
who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note at any time. Upon receipt of a request
for such an exchange or transfer, the Trustee shall cancel the applicable Unrestricted Definitive Note and the Registrar shall
increase or cause to be increased the aggregate principal amount of one of the Unrestricted Global Notes.

 

    69 

     

    

 

If any such exchange or transfer from a
Definitive Note to a beneficial interest is effected pursuant to subparagraph (2)(ii) or (3) above at a time when an Unrestricted
Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Issuer Order in accordance with Section 2.2
hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal
amount of Definitive Notes so transferred.

 

(e)                    
Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and
such Holder’s compliance with the provisions of this Section 2.6(e), the Registrar shall register the transfer or exchange
of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the
Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar
duly executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder shall provide any
additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section
2.6(e).

 

(1)           
Restricted Definitive Notes to Restricted Definitive Notes. Any Restricted Definitive Note may be transferred to
and registered in the name of Persons who take delivery thereof in the form of a Restricted Definitive Note if the Registrar receives
the following:

if the Holder of such Restricted Definitive Note proposes to transfer such Notes to a Person who shall take delivery thereof
in the form of an Unrestricted Definitive Note, a certificate from such Holder in the form of Exhibit B hereto, including
the certifications in item (4) thereof;

 

and, in each such case, if the Registrar or the Issuer so requests,
an Opinion of Counsel to the effect that such exchange or transfer is in compliance with the 1933 Act and state “blue
sky” laws and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required
in order to maintain compliance with the 1933 Act.

 

(3)           
Unrestricted Definitive Notes to Unrestricted Definitive Notes. A Holder of Unrestricted Definitive Notes may transfer
such Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request to

Canadian Legend. Each Global Note and each Definitive Note (and all Notes issued in exchange therefor or substitution

(A)           
Each Note (whether a Global Note or a Definitive Note), and all Notes issued in exchange therefor or substitution thereof,
shall also bear a legend (the “Canadian Legend”) in substantially the following form until such time as (i)
a trade of such Note in any province or territory Canada would not be a “distribution” or a “primary distribution
to the public” (each within the meaning of applicable Canadian Securities Legislation) and (ii) such Note is not otherwise
required to carry the Canadian Legend under applicable Canadian Securities Legislation:

 

“EXCEPT IN THE PROVINCE
OF MANITOBA, UNLESS PERMITTED UNDER CANADIAN SECURITIES LEGISLATION, THE HOLDER OF THE SECURITY EVIDENCED HEREBY MUST NOT TRADE
THE SECURITY BEFORE THE DATE THAT IS FOUR MONTHS AND A DAY AFTER [INSERT DISTRIBUTION DATE].

DAY AFTER THE DATE THE PURCHASER ACQUIRED THE SECURITY.”

 

    75

     

    

 

(B)           
The distribution date to be inserted into the Canadian Legend pursuant to subparagraph (A) above shall be, in the case of
the Initial Notes, the Issue Date or, in the case of any Additional Notes, the “distribution date” (within the meaning
of National Instrument 45-102 Resale of Securities) for such Additional Notes.

 

(g)                    
Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note
have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not
in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.10 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 by the Notes Custodian 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 Notes Custodian at the direction of the Trustee to reflect such increase.

 

(h)                    
General Provisions Relating to Transfers and Exchanges.

 

(1)           
To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes
and Definitive Notes upon receipt of an Issuer Order.

 

(2)           
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 tax or similar
charge or other fee required by law and payable in connection therewith (other than any taxes or similar charge payable upon exchange
or transfer pursuant to Sections 2.9, 3.6, 3.7, 4.5 and 4.7 hereof).

 

(3)           
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 under this Indenture,
as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

 

(4)           
None of the Issuer, the Trustee or the Registrar shall be required (A) to issue, to register the transfer of or to exchange
any Notes during a period of 15 days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending
at the close of business on the day of selection, (B) to register the transfer of or to exchange any Notes so selected for redemption
in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to
exchange a Note between a record date and the next succeeding Interest Payment Date.

 

    76

     

    

 

(5)           
Prior to the due presentation for registration of transfer of any Note, the Issuer, each Guarantor, the Trustee, the Paying
Agent or the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for
the purpose of receiving payment of principal, interest and premium (if any) on such Note and for all other purposes whatsoever,
whether or not such Note is overdue, and none of the Issuer, the Trustee, the Paying Agent or the Registrar shall be affected by
notice to the contrary.

 

(6)           
The Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Issuer Order and in accordance with
the other provisions of Section 2.2 hereof.

 

(7)           
All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section
2.6 to effect a registration of transfer or exchange may be submitted by facsimile.

 

(8)           
None of the Trustee or any Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest
in any Note (including any transfers between or among Depositary participants, members or beneficial owners in any Global 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.

 

(9)           
None of the Trustee or any Agent shall have any responsibility or obligation to any beneficial owner of a Global Note, a
member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or
its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the
delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any
notice of optional redemption) or the payment of any amount, under or with respect to such Notes.

 

Section 2.7.         
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 receipt of an Issuer Order conforming to Section 2.2 hereof, will authenticate
a replacement Note of like tenor and principal amount if the Trustee’s and the Issuer’s reasonable requirements are
met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee and the Issuer to protect the Issuer, the Trustee, any other Agent and any Authenticating Agent from any loss that
any of them may suffer if a Note is replaced. The Issuer may charge for its expenses (including any tax or charge that may be imposed
in connection therewith and the fees and expenses of the Trustee) in replacing a Note.

 

    77

     

    

 

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

 

Notwithstanding any other provision of this
Section 2.7, rather than authenticating and delivering a replacement Note for a mutilated, destroyed, loss or stolen Note which
has been redeemed or the principal of which has matured, the Issuer or the Paying Agent may make payment of the amount due on such
security to the Holder upon receipt of the above-described indemnity bond.

 

Section 2.8.         
Outstanding 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, those reductions
in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 12.5 hereof, a Note does not cease to be outstanding because the Issuer,
a Guarantor or an Affiliate of the Issuer or a Guarantor holds the Note.

 

If a Note is replaced pursuant to Section
2.7 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 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

 

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

 

Section 2.9.         
Temporary Notes.

 

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

  

    78

     

    

 

Section 2.10.     
Cancellation.

 

The Issuer at any time may deliver Notes
to the Trustee or any Registrar for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. The Trustee or the Registrar (and no one else) shall cancel and destroy
(subject to the Trustee’s procedures and the record retention requirements of the 1934 Act) all Notes surrendered for registration
of transfer, exchange, payment, replacement or cancellation and deliver a certificate of such destruction to the Issuer (provided
that the Trustee or such Registrar shall deliver a copy of such cancelled Note to the Issuer upon request prior to destruction).
The Issuer may not issue new Notes to replace Notes it has redeemed, paid or delivered to the Trustee or the Registrar for cancellation.

 

Section 2.11.     
Defaulted Interest.

 

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

 

Section 2.12.     
CUSIP Numbers.

 

The Issuer in issuing the Notes may use
 “CUSIP,” “ISIN” or similar numbers (if then generally in use) and, if so, the Trustee shall use such numbers
in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation
is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption 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 will promptly notify the Trustee in writing of any change in
the “CUSIP”, “ISIN” or similar numbers.

 

Section 2.13.     
Calculations.

 

The Issuer will be responsible for making
all calculations called for under this Indenture or the Notes. The Issuer will make all such calculations in good faith and, absent
manifest error, its calculations will be final and binding on Holders. The Issuer will provide a schedule of its calculations to
the Trustee when reasonably requested by the Trustee, and the Trustee is entitled to rely conclusively upon the accuracy of such
calculations without independent verification. The Trustee will deliver a copy of any such schedule to any Holder upon the written
request of such Holder.

 

    79

     

    

 

Article
III

REDEMPTION

 

Section 3.1.         
Notices to Trustee.

 

If the Issuer elects to redeem Notes pursuant
to Section 3.7 or Section 3.8 hereof, it shall notify the Trustee in writing of the Redemption Date and the principal amount of
Notes to be redeemed.

 

The Issuer shall give each notice to the
Trustee and the Registrar provided for in this Section 3.1 at least five (5) Business Days before the date of giving notice of
the redemption pursuant to Section 3.3, unless the Trustee consents to a shorter period. Such notice shall be accompanied by an
Officer’s Certificate stating that such redemption will comply with the conditions therein.

 

Section 3.2.         
Selection of Notes to Be Redeemed.

 

In the case of any partial redemption of
the Notes selection of the Notes for redemption will be made by the Trustee (i) if the Issuer gives written notice to the Trustee
that the Notes are listed in a national securities exchange, in compliance with the requirements of such exchange or (ii) if the
Issuer does not give written notice to the Trustee that the Notes are so listed, then on a pro rata basis (or, in the case of Notes
in global form, the Notes represented thereby will be selected in accordance with the Depositary’s prescribed method). The
Trustee will make the selection from outstanding Notes not previously called for redemption. The Trustee may select for redemption
portions of the principal of Notes that have denominations larger than US$1,000. Notes and portions of them the Trustee selects
will be in minimum amounts of US$2,000 or a whole multiple of US$1,000 in excess thereof. The Issuer shall notify the Trustee and
any Holder promptly of a change to the minimum denomination of any Notes. Provisions of this Indenture that apply to Notes called
for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Issuer promptly of the Notes
or portions of Notes to be redeemed. The Trustee may rely upon information provided by the Registrar for purposes of this Section
3.2. The Trustee shall not be liable for the selection made in accordance with this Section 3.2.

 

Section 3.3.         
Notice of Redemption.

 

At least 10 days but not more than 60 days
before a date for redemption of Notes, the Issuer shall mail a notice of redemption by first-class mail (or, in the case of Notes
in global form, delivered electronically in accordance with the Depositary’s procedures) to each Holder of Notes to be redeemed
at such Holder’s registered address or, with respect to Global Notes, otherwise give such notice in accordance with the Applicable
Procedures of the Depositary; provided, however, notices of redemption may be sent more than 60 days prior to a Redemption
Date if the notice is issued in connection with the Issuer’s exercise of its legal defeasance or its covenant defeasance
option in accordance with Section 8.1(b) or the satisfaction and discharge of this Indenture in accordance with Section 8.1(a).

 

    80

     

    

 

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

 

(1)           
the Redemption Date;

 

(2)           
the Redemption Price (if then determined and otherwise the basis for its determination);

 

(3)           
the name and address of the Paying Agent where Notes are to be surrendered;

 

(4)           
that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

 

(5)           
if fewer than all the outstanding Notes are to be redeemed, the identification and principal amounts of the particular Notes
to be redeemed;

 

(6)           
that, unless the Issuer defaults in making such redemption payment, interest on Notes (or portion thereof) called for redemption
ceases to accrue on and after the Redemption Date;

 

(7)           
the CUSIP, ISIN or similar number, if any, printed on the Notes being redeemed;

 

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

 

(9)           
any conditions precedent to such redemption.

 

At the Issuer’s request, the Trustee
will give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however,
that the Issuer shall have delivered to the Trustee, at least five (5) Business Days prior to the giving of notice of redemption
(or such shorter period as is acceptable to the Trustee), an Officer’s Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in the notice as provided in the preceding paragraph.

 

Section 3.4.         
Effect of Notice of Redemption.

 

Once notice of redemption is sent to Holders,
Notes (or portions thereof) called for redemption become irrevocably due and payable on the Redemption Date and at the Redemption
Price, subject to the satisfaction of any condition permitted below. A notice of redemption (including in connection with a transaction
(or series of related transactions) or an event that constitutes a Change of Control Triggering Event) may, at the Issuer’s
discretion, be given prior to the completion or the occurrence thereof and any such redemption or purchase may, at the Issuer’s
discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related
transaction or event, as the case may be. In addition, if such redemption or purchase is subject to the satisfaction of one or
more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s
discretion, the redemption or purchase may be delayed until such time (including more than 60 days after the date the notice of
redemption or offer to purchase was mailed or delivered, including by electronic transmission) as any or all such conditions shall
be satisfied or waived, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or
all such conditions shall not have been satisfied or waived by the redemption or purchase date, or by the redemption or purchase
date so delayed, or such notice or offer may be rescinded at any time in the Issuer’s discretion if in the good faith judgment
of the Issuer any or all of such conditions will not be satisfied or waived. In addition, the Issuer may provide in such notice
or offer that payment of the redemption or purchase price and performance of the Issuer’s obligations with respect to such
redemption or offer to purchase may be performed by another Person. In no event shall the Trustee be responsible for monitoring,
or charged with knowledge of, the maximum aggregate amount of the Notes eligible under this Indenture to be redeemed or the actual
amount of the Notes to be redeemed without notice thereof from the Issuer. Upon surrender to the Paying Agent, such Notes shall
be paid at the Redemption Price stated in the notice, plus accrued and unpaid interest to, but not including, the Redemption Date;
provided that if the Redemption Date is after the taking of a record of the Holders on a record date and on or prior to
the related Interest Payment Date, the accrued and unpaid interest shall be payable to the Person in whose name the redeemed Notes
are registered on such record date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

to be redeemed on that date. If the Issuer complies with the provisions of this Section 3.5, then on and after the Redemption Date,
interest will cease to accrue on the Notes or the portions of Notes called for redemption.

Notes Redeemed in Part.

 

Upon cancellation of a Note that is redeemed
in part, the Issuer shall issue and the Trustee shall, upon receipt of an Issuer Order, authenticate for the Holder (at the Issuer’s
expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered. The Trustee shall notify the Registrar
of the issuance of such new Note.

redeem all or a part of the Notes at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Notes redeemed
and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any
portion of such payments of interest accrued as of the Redemption Date) that would be due if the Notes matured on the Par Call
Date, discounted to the Redemption Date for the Notes on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Rate, plus 50 basis points, plus accrued and unpaid interest thereon to, but excluding, the Redemption

Redemption Date.

The Notes will not be redeemable at the option of the Issuer except as set forth in this Section 3.7, Section 3.8 and Section
4.7(i). The Issuer is not, however, prohibited from acquiring the Notes by means other than a redemption, whether pursuant to a
tender offer, open market transactions, by private purchase or otherwise, so long as the acquisition does not otherwise violate
the terms of this Indenture.

Jurisdiction which is announced and becomes effective on or after the Issue Date (or, where a jurisdiction in question does not
become a Relevant Taxing Jurisdiction until a later date, such later date); or

 

		(2)	any amendment to, or change in, the existing official position or the introduction of an official position regarding the application,
interpretation, administration or assessing practices of any such laws, regulations or rulings of any Relevant Taxing Jurisdiction,

making payment through a paying agent located in another jurisdiction), then the Issuer may, at its option, redeem all but not
less than all of the Notes, upon not more than 60 days’ notice prior to the earliest date on which the Issuer or a Guarantor,
as applicable, would be required to pay such Additional Amounts or indemnification payments, at a Redemption Price of 100% of their
principal amount, plus accrued and unpaid interest, if any, to the Redemption Date. Prior to the giving of any notice of redemption
described in this Section 3.8, the Issuer will deliver to the Trustee a written opinion of independent legal counsel to the Issuer

in this Section 3.8.

or prospects of the Issuer and its Restricted Subsidiaries, taken as a whole, or if the Issuer determines in its good faith judgment
that such disclosure would otherwise cause competitive harm to the business, assets, operations, financial position or prospects
of the Issuer and its Restricted Subsidiaries, taken as a whole (in which event such nondisclosure shall be limited only to specific
provisions that would cause material harm and not the occurrence of the event itself) and (b) in no event will any financial statements

(b)                    
The Issuer will, within 15 Business Days after providing to the Trustee any Financial Report, hold a conference call to
discuss such Financial Report and the results of operations for the applicable reporting period. If the Issuer does not file reports
with the SEC, then the Issuer will also maintain a website to which Holders, prospective investors and securities analysts are

to Section 4.2(a), the Issuer (i) makes available such Financial Reports and (ii) provides details about how to access on a toll-free
basis the quarterly conference calls described above.

 

    85

     

    

 

(c)                    
Notwithstanding the foregoing, (1) all Financial Reports will be deemed to have been provided to the Trustee and to the
Holders to the extent filed (i) on the System for Electronic Document Analysis and Retrieval (“SEDAR”) or any
successor system thereto or (ii) with the Commission via the Electronic Data Gathering, Analysis and Retrieval (“EDGAR”)
filing system or any successor system thereto, (2) the requirements of this Section 4.2 will be deemed satisfied by the posting
of reports that would be required to be provided to the Holders on the Issuer’s website (or that of any of the Issuer’s
parent companies), and (3) if the Issuer holds a quarterly conference call for its equity holders within 15 Business Days of filing
a Financial Report on SEDAR or any successor system thereto, the Issuer will no longer be required to hold a separate conference
call in respect of such Financial Report for the Holders as provided above. The Trustee will not be responsible for monitoring
compliance with filings on SEDAR or EDGAR.

 

(d)                    
In addition, for so long as any Notes remain outstanding during any period when the Issuer is not subject to Section 13
or 15(d) of the 1934 Act, or otherwise permitted to furnish the Commission with certain information pursuant to Rule 12g3-2(b)
of the 1934 Act, the Issuer will furnish to Holders of Notes and to prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the 1933 Act.

 

(e)                    
Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its
obligations hereunder for purposes of Section 6.1(3) until 120 days after the date any report under this Section 4.2 is due.

 

Delivery of reports, information and documents
to the Trustee hereunder is for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute
constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s
compliance with any of their covenants hereunder (as to which Trustee is entitled to rely exclusively on Officer’s Certificates).

 

Section 4.3.         
Limitation on Liens.

 

(a)                    
The Issuer will not, and will not permit any of the Guarantors to, directly or indirectly, create, incur or assume any Lien
(except Permitted Liens) on the Collateral or any property that secures Indebtedness, unless the Notes are equally and ratably
secured with (or, at the Issuer’s option on a senior basis to) the Indebtedness so secured.

 

(b)                    
Any Lien created for the benefit of the Holders pursuant to Section 4.3(a) shall provide by its terms that such Lien shall
be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to the obligation
to secure the Notes.

 

    86

     

    

 

 

Section 4.4.         
Limitation on Sale and Lease-Back Transactions.

 

The Issuer will not, and will not permit
any Guarantor to, enter into any Sale and Lease-Back Transaction with respect to any property unless (a) the Issuer or such Guarantor
would be entitled to incur Indebtedness secured by a Lien on the property involved in such transaction at least equal in amount
to the Attributable Debt with respect to such Sale and Lease-Back Transaction without equally and ratably securing the Notes pursuant
to Section 4.3(a) or (b) the Issuer shall apply an amount equal to the net proceeds of the Attributable Debt with respect to such
Sale and Lease-Back Transaction within 365 days after such Sale and Lease-Back Transaction to the defeasance or retirement of the
Notes or other indebtedness of the Issuer or a Guarantor or to the purchase, construction or development of other assets or property.

 

Section 4.5.         
Asset Sales of Collateral.

 

(a)                    
The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale of Collateral in
any single transaction or series of related transactions unless:

 

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

 

(2)           
at least 75% of the consideration received for such Asset Sale (measured at the time of contractually agreeing to such Asset
Sale), together with all Asset Sales since February 1, 2016 (on a cumulative basis), received by the Issuer and its Restricted
Subsidiaries in the manner referred to in Section 4.5(a)(1) above is in the form of cash, Cash Equivalents, or Permitted Assets.
For purposes of this provision, each of the following will be deemed to be cash:

 

(A)           
any liabilities of the Issuer or any Restricted Subsidiary (other than contingent liabilities or liabilities that are by
their terms subordinated to the Notes or any Note Guarantee), as shown on the Issuer’s most recent internally available annual
or quarterly balance sheet, that are (i) assumed by the transferee of any such assets pursuant to a customary novation agreement
or similar agreement that releases the Issuer or such Restricted Subsidiary from further liability or (ii) otherwise canceled;

 

(B)           
any securities, notes or other obligations (including earn-outs and similar obligations) received by the Issuer or any such
Restricted Subsidiary from such transferee that are, within 180 days of the applicable Asset Sale, converted by the Issuer or such
Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents received in that conversion;

 

(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 its other Restricted Subsidiaries are released from any guarantee of payment of such Indebtedness in
connection with the Asset Sale; and

 

    87

     

    

 

(D)           
any Designated Non-cash Consideration received by the Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate
Fair Market Value (with the Fair Market Value of such item of Designated Non-cash Consideration being measured at the time of contractually
agreeing to the related Asset Sale), taken together with all other Designated Non-cash Consideration received pursuant to this
clause (D) that is at that time outstanding, not to exceed the greater of (i) $90.0 million and (ii) 3.0% of Total Assets measured
at the time of contractually agreeing to such Asset Sale.

 

(b)                    
Within 455 days after the receipt of any Net Proceeds from an Asset Sale covered by this Section 4.5 (or, at the Issuer’s
option, any earlier date), the Issuer or any Restricted Subsidiary may apply those Net Proceeds for any combination of the following
purposes:

 

(1)           
to Repay (a) Obligations under the Notes or (b) First Lien Obligations (other than the Notes), and in the case of revolving
obligations (other than obligations in respect of any asset-backed credit facility), to correspondingly reduce commitments with
respect thereto; provided that in the case of any repayment pursuant to this clause (b), the Issuer or such Restricted Subsidiary
will either (1) reduce obligations under the Notes on an equal or ratable basis with any First Lien Obligations repaid pursuant
to this clause (b) by, at its option (A) redeeming Notes as described under “Optional Redemption” or (B) purchasing
Notes through open-market purchases or in arm’s length privately negotiated transactions or (2) make an offer (in accordance
with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase their Notes for no less than 100% of the
principal amount thereof, plus the amount of accrued but unpaid interest, if any, thereon, to, but excluding, the date of purchase;

 

(2)           
to acquire all or substantially all of the assets of, or to acquire Capital Stock of, a Person that is engaged in a Permitted
Business and that, in the case of an acquisition of Capital Stock, is or becomes a Restricted Subsidiary of the Issuer;

 

(3)           
to make a capital expenditure; or

 

(4)           
to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted
Business or that replace, in whole or in part, the properties or assets that are subject to the Asset Sale.

 

Notwithstanding the foregoing, in the event
the Issuer or any of its Restricted Subsidiaries enters into a binding agreement committing to make an acquisition, expenditure
or investment in compliance with clauses (2), (3) or (4) above within 455 days after the receipt of any Net Proceeds from an Asset
Sale (an “Acceptable Commitment”), such commitment will be treated as a permitted application of the Net Proceeds
from the date of the execution of such agreement until the earlier of (i) the date on which such acquisition or investment is consummated
or such expenditure made or such agreement is terminated, and (ii) the 180th day after the expiration of the aforementioned 455-day
period; provided that if any Acceptable Commitment is later canceled or terminated for any reason before such Net Proceeds
are applied, then such Net Proceeds shall constitute Excess Proceeds from and after the date of such cancelation or termination;
unless the Issuer or such Restricted Subsidiary enters into another Acceptable Commitment within 180 days of such cancellation
or termination (a “Second Commitment”) in which case such commitment will be treated as a permitted application
of the Net Proceeds from the date of the execution of such agreement until the earlier of (i) the date on which such acquisition
or investment is consummated or such expenditure made or such agreement is terminated, and (ii) the 180th day after the date of
the Second Commitment.

 

    88

     

    

 

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

 

(c)                    
Any Net Proceeds from Asset Sales covered by this Section 4.5 that are not applied or invested as provided in Section 4.5(b)
(it being understood that any portion of such Net Proceeds used to make an offer to purchase Notes, as described in Section 4.5(b),
will be deemed to have been so applied whether or not such offer is accepted) will constitute “Excess Proceeds.”

 

(d)                    
If the aggregate amount of Excess Proceeds from an Asset Sale of Collateral covered by this Section 4.5 (“Collateral
Excess Proceeds”) exceeds $60.0 million, the Issuer will make a pro rata offer to all Holders of Notes (and, if required
or permitted by the terms of other First Lien Obligations or obligations secured by a Lien permitted under this Indenture on the
assets disposed of, which Lien is not subordinate to the Lien of the Notes with respect to the Collateral), to the holders of such
other First Lien Obligations or such other obligations (an “Asset Sale Offer”), to purchase the maximum aggregate
principal amount (or accreted value, as applicable) of Notes and such other First Lien Obligations or such other obligations, as
the case may be, that may be purchased out of the Excess Proceeds. The offer price, with respect to the Notes only, in any Asset
Sale Offer will be equal to 100% of the principal amount (or accreted value in the case of any such First Lien Obligations or such
other obligations, as the case may be, issued with a significant original issue discount) plus accrued and unpaid interest, if
any, to, but excluding, the date of purchase, and will be payable in cash. If the aggregate principal amount of Notes and other
First Lien Obligations or such other obligations, as the case may be, tendered into such Asset Sale Offer exceeds the amount of
Excess Proceeds, the Trustee will select the Notes and such other First Lien Obligations or such other obligations, as the case
may be, to be purchased on a pro rata basis (subject to the procedures of the relevant depositary), on the basis of the aggregate
principal amounts (or accreted values) tendered in round denominations (which, in the case of the Notes, will be minimum denominations
of US$2,000 principal amount and multiples of US$1,000 in excess thereof).

 

(e)                    
If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will
be reset at zero. The Issuer may satisfy the foregoing obligations with respect to such Net Proceeds from an Asset Sale by making
an Asset Sale Offer with respect to such Net Cash Proceeds at any time prior to the expiration of the application period or by
electing to make an Asset Sale Offer with respect to such Net Proceeds before the aggregate amount of Excess Proceeds exceeds $60.0
million.

 

    89

     

    

 

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

 

(g)                    
On the Asset Sale Payment Date, the Issuer will, to the extent lawful:

 

(1)           
accept for payment all Notes or portions thereof properly tendered pursuant to the Asset Sale Offer, subject to proration
based on the amount of Excess Proceeds pursuant to Section 4.5(c);

 

(2)           
deposit with the Paying Agent an amount equal to the amount of Excess Proceeds that, after giving effect to proration with
holders of Pari Passu Indebtedness pursuant to Section 4.5(c), is allocable to the Notes or portions thereof so tendered (or, if
less, the aggregate payment for all Notes validly tendered and not withdrawn); and

 

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

 

(h)                    
The Paying Agent will promptly mail (or cause to be transferred through the facilities of the Depositary) to each Holder
of Notes accepted for payment in accordance with this Section 4.5, the payment for such tendered Notes, and the Trustee will, upon
receipt of an Issuer Order, promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any, by such Holder; provided that each
such new Note will be in a principal amount of US$1,000 or an integral multiple thereof.

 

(i)                    
To the extent that the aggregate amount of Notes and such other First Lien Obligations or Notes Obligations secured by a
Lien permitted under this Indenture (which Lien is not subordinate to the Lien of the Notes with respect to the Collateral) tendered
or otherwise surrendered in connection with an Asset Sale Offer made with Excess Proceeds is less than the amount offered in an
Asset Sale Offer, the Issuer may use any remaining Excess Proceeds for any purpose not otherwise prohibited by this Indenture.

 

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

 

(k)                    
The Issuer will comply with all applicable securities legislation of Canada and the United States, including, without limitation,
the requirements of Rule 14e-1 under the 1934 Act and any other applicable securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent
that the provisions of any applicable securities laws and regulations conflict with this Indenture, the Issuer will comply with
such laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance.

 

    90

     

    

 

(l)                    
The Issuer’s obligation to make an Asset Sale Offer may be waived or modified before or after the occurrence of an
Asset Sale with the written consent of Holders of at least a majority in principal amount of the Notes then outstanding. Notwithstanding
the foregoing, any sale, assignment, transfer, conveyance, lease or other disposition of all or substantially all of the properties
or assets of the Issuer and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person,
will be governed by Section 5.1 and will not be subject to the provisions described above in this Section 4.5.

 

Section 4.6.         
Issuance of Note Guarantees.

 

(a)                    
The Issuer will cause each Material Restricted Subsidiary that is not a Guarantor and that guarantees the obligations under
the First Lien Term Loan Credit Agreement or the Existing Secured Notes to become a Guarantor, execute and deliver a supplemental
indenture in the form of Exhibit D and joinders to the Collateral Documents or new Collateral Documents together with any
other filings and other agreements required by the Collateral Documents to create or perfect the security interests for the benefit
of the Notes Secured Parties in the Collateral of such Subsidiary, and deliver an Officer’s Certificate and Opinion of Counsel
reasonably satisfactory to the Trustee, in each case within 30 days of the date on which such Material Restricted Subsidiary was

Section 4.7.         
Change of Control Triggering Event.

 

(a)                    
If a Change of Control Triggering Event occurs, unless, prior to, or concurrently with, the time the Issuer is required
to make a Change of Control Offer (as defined below), the Issuer has previously or concurrently mailed or delivered, or otherwise
sent through electronic transmission, a redemption notice with respect to all the outstanding Notes as described under Section
3.7 or Article VIII, the Issuer will make an offer to purchase all of the Notes pursuant to the offer described below (the “Change
of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate
principal amount thereof (or such higher amount as the Issuer may determine) plus accrued and unpaid interest, if any, to, but
excluding, the date of purchase, subject to the right of Holders of record on the relevant Record Date to receive interest due
on the relevant Interest Payment Date falling on or prior to the Change of Control Payment Date (as defined below). Within 30 days
following any Change of Control Triggering Event, the Issuer will send notice of such Change of Control Offer electronically or
by first-class mail, with a copy to the Trustee sent in the same manner, to each Holder to the address of such Holder appearing
in the security register or otherwise in accordance with the procedures of DTC, with the following information:

 

(1)           
that a Change of Control Offer is being made pursuant to this Section 4.7 and that all Notes properly tendered pursuant
to such Change of Control Offer will be accepted for payment by the Issuer;

 

(2)           
the purchase price and the purchase date, which will be no earlier than 10 days nor later than 60 days from the date such
notice is sent (the “Change of Control Payment Date”); provided that the Change of Control Payment Date
may be delayed, in the Issuer’s discretion, until such time (including more than 60 days after the date such notice. is sent)
as any or all such conditions referred to in Section 4.7(a)(8) shall be satisfied or waived;

 

(3)           
that any Note not properly tendered will remain outstanding and continue to accrue interest;

 

(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 will cease to accrue interest on the Change of Control Payment Date;

 

(5)           
that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed or otherwise
in accordance with the procedures of DTC, to the paying agent specified in the notice at the address specified in the notice prior
to the close of business on the third Business Day preceding the Change of Control Payment Date;

 

(6)           
that Holders will be entitled to withdraw their tendered Notes and their election to require the Issuer to purchase such
Notes; provided that the paying agent receives, not later than the close of business on the second Business Day prior to
the expiration time of the Change of Control Offer, an electronic transmission (in PDF), a facsimile transmission or letter setting
forth the name of the Holder or otherwise in accordance with the procedures of DTC, the principal amount of the Notes tendered
for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

 

(7)           
that if less than all of such Holder’s Notes are tendered for purchase, such Holder will be issued new Notes and such
new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered; provided that the unpurchased
portion of the Notes must be equal to at least US$2,000 or an integral multiple of US$1,000 in excess of US$2,000;

 

(8)           
if such notice is sent prior to the occurrence of a Change of Control Triggering Event, stating that the Change of Control
Offer is conditional on the occurrence of such Change of Control Triggering Event and describing each such condition, and, if applicable,
stating that, in the Issuer’s discretion, the Change of Control Payment Date may be delayed until such time as any or all
such conditions shall be satisfied or waived, or that such purchase may not occur and such notice may be rescinded in the event
that the Issuer shall determine that any or all such conditions (including the occurrence of the Change of Control Triggering Event)
shall not have been satisfied or waived by the Change of Control Payment Date, or by the Change of Control Payment Date as so delayed;
and

 

    92

     

    

 

(9)           
such other instructions, as determined by the Issuer, consistent with this covenant, that a Holder must follow.

 

(b)                    
While the Notes are in global form and the Issuer makes an offer to purchase all of the Notes pursuant to the Change of
Control Offer, a Holder may exercise its option to elect for the purchase of Notes through the facilities of DTC, subject to its
rules and regulations.

 

(c)                    
The Issuer will comply with all applicable securities legislation in Canada and the United States including, without limitation,
the requirements of Rule 14e-1 under the 1934 Act and any other securities laws and regulations thereunder to the extent those
laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering
Event. To the extent that the provisions of any applicable securities laws and regulations conflict with the provisions of this
Section 4.7, the Issuer will comply with such laws and regulations and will not be deemed to have breached its obligations under
this Section 4.7 by virtue of such compliance.

 

(d)                    
On the Change of Control Payment Date, the Issuer or its designated agent will, to the extent lawful:

 

(1)           
accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

 

(2)           
deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes
properly tendered; and

 

(3)           
deliver or cause to be delivered to the Trustee the Notes accepted together with an Officer’s Certificate stating
the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

 

(e)                    
On the Change of Control Payment Date, the paying agent will promptly transmit to each Holder of Notes properly tendered
and not withdrawn the Change of Control Payment for such tendered Notes, and the Trustee, upon an order of the Issuer, will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount that is US$2,000 or
an integral multiple of US$1,000 in excess thereof. The Issuer will publicly announce the results of the Change of Control Offer
on or as soon as practicable after the Change of Control Payment Date.

 

(f)                    
If the Change of Control Payment Date is on or after a Record Date and on or before the related Interest Payment Date, any
accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such Record
Date, and no other interest will be payable to Holders who tender pursuant to the Change of Control Offer.

 

(g)                    
The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control Triggering
Event will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect
to a Change of Control Triggering Event, this Indenture does not contain provisions that permit the Holders to require that the
Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

 

    93

     

    

 

(h)                    
Notwithstanding the preceding paragraphs of this Section 4.7, the Issuer will not be required to make a Change of Control
Offer upon a Change of Control Triggering Event if a third party makes an offer to purchase the Notes in the manner, at the times
and otherwise in substantial compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer
made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, or a notice of
redemption has been given pursuant to Section 3.7, unless and until there is a default in payment of the applicable Redemption
Price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by the Issuer or a third party may
be made in advance of a Change of Control Triggering Event, conditioned upon the consummation of such Change of Control Triggering
Event, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

 

(i)                    
In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes validly tender
and do not withdraw such Notes in a Change of Control Offer and the Issuer (or any third party making a Change of Control Offer
in lieu of the Issuer as described above) purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer
or such third party, as applicable, will have the right, upon not less than 10 nor more than 60 days’ prior notice, given
not more than 30 days following the purchase pursuant the Change of Control Offer described above, to redeem (in the case of the
Issuer) or purchase (in the case of a third party offeror) all of the Notes that remain outstanding following such purchase on
a date (the “Second Change of Control Payment Date”) at a Redemption Price or purchase price, as the case may
be, in cash equal to the Change of Control Payment (excluding any early tender premium or similar premium and any accrued and unpaid
interest to any Holder in such Change of Control Payment) in respect of the Second Change of Control Payment Date, including, to
the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain outstanding,
to, but excluding, the Second Change of Control Payment Date (subject to the right of Holders of record on the relevant Record
Date to receive interest due on an Interest Payment Date that is on or prior to the Second Change of Control Payment Date).

 

The Issuer’s obligation to make a
Change of Control Offer following a Change of Control Triggering Event may be waived or modified before or after the occurrence
of such Change of Control with the written consent of Holders of at least a majority in aggregate principal amount of the Notes
then outstanding.

 

Section 4.8.         
Maintenance of Office or Agency for Registration of Transfer, Exchange and Payment of Notes.

 

So long as any of the Notes shall remain
outstanding, the Issuer will, in accordance with Section 2.2 hereof, maintain an office or agency (which may be an office of the
Trustee or an affiliate of the Trustee, or the Registrar) in the continental U.S. where the Notes may be surrendered for exchange
or registration of transfer and where the Notes may be presented or surrendered for payment. If the Issuer shall fail to maintain
any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, such surrenders
or presentations may be made at the designated Corporate Trust Office, and the Issuer hereby appoints the Trustee its agent to
receive at the aforesaid office all such surrenders or presentations. The Issuer may also from time to time designate one or more
other offices or agencies in the continental U.S. where Notes may be presented or surrendered for any and all such purposes and
may from time to time rescind such designations. The Issuer will give to Trustee prompt written notice of the location of any such
office or agency and of any change of location thereof.

 

    94

     

    

 

Section 4.9.         
Appointment to Fill a Vacancy in the Office of Trustee.

 

The Issuer, whenever necessary to avoid
or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.7, a Trustee, so that there shall
at all times be a Trustee hereunder.

 

Section 4.10.     
Provision as to Paying Agent.

 

(a)                    
If the Issuer will appoint a Paying Agent other than the Trustee, in accordance with the terms of this Indenture, it will
cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Agent shall undertake, subject to the
provisions of this Section 4.10:

 

(1)           
that it will hold all sums held by it as such agent for the payment of the principal of, premium, if any, or interest on

of the Holders of the Notes and will notify the Trustee of the receipt of sums to be so held;

 

(2)

of the principal of, premium, if any, or interest on the Notes when the same shall be due and payable;

 

(3)           
that it will at any time during the continuance of any Event of Default specified in Section 6.1, upon the written request
of the Trustee, deliver to the Trustee all sums so held in trust by it; and

 

(4)           
that it will acknowledge, accept and agree to comply in all aspects with the provisions of this Indenture relating to the
duties, rights and liabilities of such Paying Agent.

 

(b)                    
If the Issuer shall not act as its own Paying Agent, it will, by 11:00 a.m. (New York City time) on the due date of the
principal of or premium, if any, or interest on any Notes, deposit with such Paying Agent a sum in same day funds sufficient to
pay the principal of, premium, if any, or interest so becoming due, such sum to be held in trust for the benefit of the Trustee
and the Holders of Notes entitled to such principal of or premium, if any, or interest, and (unless such Paying Agent is the Trustee)
the Issuer will promptly notify the Trustee of its failure so to act.

 

(c)                    
If the Issuer shall act as its own Paying Agent, it will, by 11:00 a.m., (New York City time) on each due date of the principal
of or premium, if any, or interest on the Notes, set aside, segregate and hold in trust for the benefit of the Persons entitled
thereto, a sum sufficient to pay such principal or premium or interest so becoming due and will notify the Trustee of any failure
to take such action.

 

    95

     

    

 

(d)                    
Anything in this Section 4.10 to the contrary notwithstanding, the Issuer may, at any time, for the purpose of obtaining
a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Paying Agent for delivery
to the Trustee all sums held in trust by it, as required by this Section 4.10, such sums to be delivered by the Paying Agent to
the Trustee to be held by the Trustee upon the trusts herein contained.

 

(e)                    
Anything in this Section 4.10 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section
4.10 is subject to the provisions of Section 8.4 and Section 8.6.

 

(f)                    
Upon an Event of Default under Section 6.1(7), the Trustee shall be the Paying Agent.

 

Section 4.11.     
Maintenance of Corporate Existence.

 

So long as any of the Notes shall remain
outstanding, the Issuer will at all times (except as otherwise provided or permitted in Article V of this Indenture) do or cause
to be done all things necessary to preserve and keep in full force and effect its corporate existence.

 

Section 4.12.     
Compliance Certificate.

 

(a)                    
The Issuer and the Guarantors will deliver to the Trustee within 90 days after the end of each fiscal year of the Issuer,
beginning with the fiscal year ended December 31, 2021, a statement (which need not be an Officer’s Certificate) signed by
the principal executive officer, the principal accounting officer or the principal financial officer of each of the Issuer and
the Guarantors, stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has
been made under the supervision of the signing Officers with a view to determining whether each of the Issuer and the Guarantors
has performed its obligations under this Indenture, and further stating whether or not, to the knowledge of the signers, the Issuer
is in default in the performance and observance of any of the terms, provisions and conditions hereof (without regard to any period
of grace or requirement of notice provided hereunder) and if any Default or Event of Default occurred during such period. In the
event of any such default, the certificate will describe such default, its status and what action the Issuer is taking or proposes
to take with respect thereto.

 

(b)                    
So long as any of the Notes are outstanding, the Issuer will deliver to the Trustee, promptly upon any Officer becoming
aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action
the Issuer is taking or proposes to take with respect thereto.

 

Section 4.13.     
Taxes.

 

The Issuer will pay, and will cause each
of its Restricted Subsidiaries to pay, prior to delinquency, all material taxes, assessments and governmental levies except such

adverse effect on the financial condition of the Issuer and its Restricted Subsidiaries, taken as a whole.

 

    96

     

    

 

Section 4.14.     
Stay, Extension and Usury Laws.

 

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

 

Section 4.15.     
Additional Amounts.

 

(a)                    
All payments made by or on behalf of the Issuer or any Guarantor (each a “Payor”) under or with respect
to the Notes or any Note Guarantee will be made free and clear of and without withholding or deduction for or on account of any
present or future Taxes, unless such Payor is required to withhold or deduct Taxes by law or by the interpretation or administration
thereof. If a Payor is so required to withhold or deduct any amount for or on account of Taxes imposed or levied by or on behalf
of any jurisdiction in which such Payor is organized, resident or carrying on business for tax purposes or from or through which
such Payor makes any payment on the Notes or any Note Guarantee or any department or political subdivision thereof (each, a “Relevant
Taxing Jurisdiction”) from any payment made under or with respect to the Notes or any Note Guarantee, such Payor, subject
to the exceptions stated below, will pay such additional amounts (“Additional Amounts”) as may be necessary
such that the net amount received in respect of such payment by each Holder or Beneficial Holder after such withholding or deduction
(including withholding or deduction attributable to Additional Amounts payable hereunder but excluding Taxes on net income) will
not be less than the amount the Holder or Beneficial Holder, as the case may be, would have received if such Taxes had not been
required to be so withheld or deducted.

 

(b)                    
A Payor will not, however, pay Additional Amounts to a Holder or Beneficial Holder with respect to:

 

(1)           
Canadian withholding Taxes imposed on a payment to a Holder or Beneficial Holder with which the Payor does not deal at arm’s
length for the purposes of the Tax Act at the time of making such payment (other than where the non-arm’s length relationship
arises as a result of the exercise or enforcement of rights under any Notes or any Note Guarantee);

 

(2)           
a debt or other obligation to pay an amount to a person with whom the applicable Payor is not dealing at arm’s length
within the meaning of the Tax Act (other than where the non-arm’s length relationship arises as a result of the exercise
or enforcement of rights under any Notes or any Note Guarantee);

 

    97

     

    

 

(3)           
any Canadian withholding Taxes imposed on a payment or deemed payment to a Holder or Beneficial Holder by reason of such
Holder or Beneficial Holder being a “specified shareholder” of the Issuer (within the meaning of subsection 18(5) of
the Tax Act) at the time of payment or deemed payment, or by reason of such Holder or Beneficial Holder not dealing at arm’s
length for the purposes of the Tax Act with a “specified shareholder” of the Issuer at the time of payment or deemed
payment (other than where the Holder or Beneficial Holder is a “specified shareholder,” or does not deal at arm’s
length with a “specified shareholder,” as a result of the exercise or enforcement of rights under any Notes or any
Note Guarantee);

 

(4)           
Taxes giving rise to such Additional Amounts that would not have been imposed but for the existence of any present or former
connection between such Holder (or the Beneficial Holder of, or person ultimately entitled to obtain an interest in, such Notes,
including a fiduciary, settler, beneficiary, member, partner, shareholder or other equity interest owner of, or possessor of power
over, such Holder or Beneficial Holder, if such Holder or Beneficial Holder is an estate, trust, partnership, limited liability
company, corporation or other entity) and the Relevant Taxing Jurisdiction (including being a citizen or resident or national of,
or carrying on a business or maintaining a permanent establishment in, the Relevant Taxing Jurisdiction but not including any connection
resulting solely from the acquisition, ownership, or disposition of Notes, the receipt of payments thereunder and/or the exercise
or enforcement of rights under any Notes or any Note Guarantee);

 

(5)           
Taxes giving rise to such Additional Amounts that would not have been imposed but for the failure of such Holder or Beneficial
Holder, to the extent such Holder or Beneficial Holder is legally eligible to do so, to timely satisfy any certification, identification,
information, documentation or other reporting requirements concerning such Holder’s or Beneficial Holder’s nationality,
residence, identity or connection with the Relevant Taxing Jurisdiction or arm’s length relationship with the Payor or otherwise
establish the right to the benefit of an exemption from, or reduction in the rate of, withholding or deduction, if such compliance
is required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction as a precondition to exemption
from, or reduction in the rate of deduction or withholding of, such Taxes imposed by the Relevant Taxing Jurisdiction (including,
without limitation, a certification that the Holder or Beneficial Holder is not resident in the Relevant Taxing Jurisdiction);

 

(6)           
any estate, inheritance, gift, sales, transfer, personal property, excise or any similar Taxes or assessment;

 

(7)           
any Taxes that were imposed with respect to any payment on a Note to any Holder who is a fiduciary or partnership or person
other than the sole beneficial owner of such payment and to the extent the Taxes giving rise to such Additional Amounts would not
have been imposed on such payment had the Holder been the beneficiary, partner or sole beneficial owner, as the case may be, of
such Note;

 

(8)           
Taxes imposed on, or deducted or withheld from, payments in respect of the Notes if such payments could have been made without
such imposition, deduction or withholding of such Taxes had such Notes been presented for payment (where presentation is required)
within 30 days after the date on which such payments or such Notes became due and payable or the date on which payment thereof
is duly provided for, whichever is later (except to the extent such Holder or Beneficial Holder would have been entitled to such
Additional Amounts had such Notes been presented on the last day of such 30 day period);

 

    98

     

    

 

(9)           
any Tax which is payable otherwise than by deduction or withholding from payments made under or with respect to the Notes
or any Note Guarantee;

 

(10)           
any Taxes that are imposed or withheld as a result of the presentation of any Note for payment by or on behalf of a Holder
or Beneficial Holder who would have been able to avoid such withholding or deduction by presenting the relevant Note to another
paying agent;

 

(11)           
any Taxes imposed under FATCA; or

 

(12)           
any combination of the foregoing subclauses (1) through (11).

 

(c)                    
At least 30 calendar days prior to each date on which any payment under or with respect to the Notes or any Note 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 30th 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 an Officer’s Certificate 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 to
pay such Additional Amounts to Holders and/or Beneficial Holders on the payment date.

 

(d)                    
The Issuer will indemnify and hold harmless the Holders and Beneficial Holders of the Notes for the amount of any Taxes
under Regulation 803 of the Tax Act, or any similar or successor provision (other than Taxes described in subclauses (1) through
(12) above (but including, notwithstanding subclause (9), any Taxes payable pursuant to Regulation 803 of the Tax Act) or Taxes
arising by reason of a transfer of the Note to a person resident in Canada with whom the transferor does not deal at arm’s
length for the purposes of the Tax Act except where such non-arm’s length relationship arises as a result of the exercise
or enforcement of rights under any Notes or any Note Guarantee) levied or imposed on and paid by such a Holder or Beneficial Holder
as a result of payments made under or with respect to the Notes or any Note Guarantee.

 

(e)                    
In addition, the Payor will pay any stamp, issue, registration, court, documentation, excise or other similar taxes, charges
and duties, including any interest, penalties and any similar liabilities with respect thereto, imposed by any Relevant Taxing
Jurisdiction at any time in respect of the execution, issuance, registration, delivery or enforcement of the Notes (other than
on or in connection with a transfer of the Notes other than the initial sale by an Initial Purchaser), any Note Guarantee or any
other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction
on any payments made pursuant to the Notes or any Note Guarantee and/or any other such document or instrument (limited, solely
in the case of taxes, charges or duties attributable to any payments with respect thereto, to any such taxes, charges or duties
imposed in a Relevant Taxing Jurisdiction that are not excluded under Sections 4.15(b)(5) through (8) and (10) and (11)).

 

    99

     

    

 

(f)                    
The obligations under this Section 4.15 will survive any termination, defeasance or discharge of this Indenture 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. Whenever this Indenture refers to, in any context, the payment of principal, premium, if any, interest
or any other amount payable under or with respect to any Note, such reference shall include the payment of Additional Amounts or
indemnification payments as described hereunder, if applicable.

 

Section 4.16.     
After-Acquired Property.

 

From and after the Issue Date, and subject
to the applicable limitations and exceptions set forth in the Collateral Documents and this Indenture (including with respect to
Excluded Assets), if the Issuer or any Guarantor acquires any property or rights which are of a type constituting Collateral under
any Collateral Document (excluding, for the avoidance of doubt, any Excluded Assets or assets not required to be Collateral pursuant
to the Collateral Documents), it will be required to execute and deliver such security instruments, financing statements and such
Officer’s Certificates and Opinions of Counsel as are required under this Indenture or any Collateral Document and to otherwise
comply with the requirements of the Collateral Requirement to provide to the Notes Collateral Agent for the benefit of the Notes
Secured Parties a perfected security interest (subject to Permitted Liens) in such after-acquired collateral and to take such actions
to add such after-acquired collateral to the Collateral, and thereupon all provisions of the this Indenture and the Collateral
Documents relating to the Collateral shall be deemed to relate to such after-acquired collateral to the same extent and with the
same force and effect, including, without limitation:

 

(a)

Issuer or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee existed on the Issue Date, or is created after
the Issue Date, if that default:

 

(A)

Subsidiary remains a Significant Subsidiary on such 60th day; or

 

(9)           
other than by reason of the satisfaction in full of all obligations under this Indenture and discharge of this Indenture
with respect to the Notes or the release of such Collateral with respect to the Notes in accordance with the terms of this Indenture
and the Collateral Documents,

 

(A)

individually or in the aggregate, such security interest under the Collateral Documents shall, at any time, cease to be a valid
and perfected security interest or shall be declared invalid or unenforceable and any such default continues for 30 days after
notice of such default shall have been given to the Issuer by the Trustee or the Holders of at least 30% of the principal amount
of the then outstanding Notes issued under this Indenture, except to the extent that any such default (A) results from the failure
of the Notes Collateral Agent to maintain possession of certificates, promissory notes or other instruments actually delivered

Documents) other than (i)(A) in accordance with the terms of the relevant Collateral Document and this Indenture, (B) the satisfaction
in full of all obligations under this Indenture or (C) any loss of perfection that results from the failure of the Notes Collateral
Agent to maintain possession of certificates delivered to it representing securities pledged under the Collateral Documents and
(ii) such default continues for 30 days after notice of such default shall have been given to the Issuer by the Trustee or the
Holders of at least 30% of the principal amount of the then outstanding Notes issued under this Indenture.

 

    106

     

    

 

Section 6.2.         
Acceleration of Maturity; Rescission and Annulment.

 

In the case of an Event of Default specified
in Section 6.1(7) or Section 6.1(8), all outstanding Notes will become due and payable immediately without further action or notice.
If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the then
outstanding Notes may declare to be immediately due and payable, by notice in writing to the Issuer and (if given by the Holders)
to the Trustee, the principal amount of all the Notes then outstanding, plus accrued but unpaid interest to the date of acceleration;
provided, however, that after any such declaration of acceleration, the Holders of a majority in aggregate principal
amount of the Notes then outstanding may rescind and annul such declaration if: (a) all existing Events of Default, other than
the non-payment of the principal of, interest and premium (if any) on the Notes that have become due solely by the declaration
of acceleration, have been cured or waived; and (b) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

 

The Trustee may withhold from Holders notice
of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or
Event of Default relating to the payment of principal or interest.

 

Section 6.3.         
Other Remedies.

 

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

 

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

 

Section 6.4.         
Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Notes then outstanding by
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 this Indenture and the Collateral Documents except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes or a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended
without the consent of each Holder affected.

 

Section 6.5.         
Control by Majority.

 

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

 

    107

     

    

 

Section 6.6.         
Limitation on Suits.

 

Except to enforce payment of the principal
of, and premium (if any) or interest on any Note on or after the Stated Maturity of such Note (after giving effect to the grace
periods specified in Section 6.1(1) and Section 6.1(2)), a Holder will not have any right to institute any proceeding with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any remedy thereunder, unless the Trustee:

 

(1)           
shall have failed to act for a period of 60 days after previously receiving written notice of a continuing Event of Default
from such Holder and a request to act from Holders of at least 30% in aggregate principal amount of the Notes then outstanding;

 

(2)           
has been offered indemnity and funding thereof, if requested, satisfactory to the Trustee in its reasonable judgment; and

 

(3)           
during such 60 day period, has not received from the Holders of a majority in aggregate principal amount of the Notes then
outstanding a direction inconsistent with such request.

 

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

 

Section 6.7.         
Rights of Holders to Receive Payment.

 

Notwithstanding any other provision of this
Indenture, the contractual right of any Holder to receive payment of principal of, premium, if any, and interest on the Notes held
by such Holder, on or after the respective due dates expressed in the Notes, or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the consent of such Holder. For the avoidance of doubt,
no amendment to, or deletion or waiver of, Article IV (other than Section 4.1), or any action taken by the Issuer or any Guarantor
that is not prohibited under this Indenture, shall be deemed to impair or affect any rights of any Holder of Notes to receive payment
of principal of, or premium, if any, or interest on, the Notes.

 

Section 6.8.         
Collection Suit by Trustee.

 

If an Event of Default specified in Section
6.1(1) or Section 6.1(2) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an
express trust against the Issuer or any Guarantor for the whole amount then due and owing (together with interest on any unpaid
interest to the extent lawful) and the amounts provided for in Section 7.6 hereof to cover the costs and expenses of collection,
including the reasonable compensation, disbursement and advances of the Trustee, its agents and counsel.

 

    108

     

    

 

 

Section 6.9.         
Trustee May File Proofs of Claim.

 

The Trustee may file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed
in any judicial proceedings relative to the Issuer or any Guarantor or their respective creditors or properties, and any Custodian
in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section
7.6 hereof. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any
Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

 

Section 6.10.     
Priorities.

 

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

 

First: to the payment of all amounts
due to the Trustee under Section 7.6 hereof and all amounts due to the Notes Collateral Agent;

 

Second: to Holders for amounts
due and unpaid on the Notes for principal and interest and premium, if any, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for principal and interest and premium, if any, respectively; and

 

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

 

The Trustee may fix a record date and payment
date for any payment to Holders pursuant to this Section 6.10.

 

Section 6.11.     
Undertaking for Costs.

 

In any suit for the enforcement of any right
or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in
its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof or a suit by Holders of more than 10%
in outstanding principal amount of the Notes.

(a)                    
If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by
this Indenture and use the same degree of care and skill in their exercise as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

the requirements of this Indenture; but in the case of any such certificates and opinions which by any provision hereof or thereof
are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether
or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations
or other facts stated therein).

the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.5 hereof.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability

(f)                    
Except for a default under Section 6.1(1) or Section 6.1(2) hereof (provided that the Trustee is the Paying Agent),
the Trustee shall not be deemed to have notice of any default or event of default unless written notice is received by a Trust
Officer of the Trustee at the Corporate Trust Office, and such notice references the Notes and this Indenture and states that it

(g)                    
In no event shall the Trustee be responsible or liable for special, incidental, indirect, punitive or consequential loss

The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request

Section 7.3.         
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 its Affiliates with the same rights
it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the
TIA) after a Default has occurred and is continuing, it must (i) eliminate such conflict within 90 days, (ii) apply to the Commission
for permission to continue or (iii) resign. The Trustee is also subject to Sections 7.9 and 7.10 hereof.

The Trustee does not assume any responsibility
for any failure or delay in performance or any breach by the Issuer or any other Grantor under this Indenture, the First Intercreditor
Agreement and the Collateral Documents. The Trustee shall not be responsible to the Holders or any other Person for any recitals,
statements, information, representations or warranties contained in this Indenture, the Collateral Documents, the First Lien Intercreditor
Agreement or in any certificate, report, statement, or other document referred to or provided for in, or received by the Trustee
under or in connection with, this Indenture, the First Lien Intercreditor Agreement or any Collateral Document; the execution,
validity, genuineness, effectiveness or enforceability of the First Lien Intercreditor Agreement and any Collateral Document of
any other party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral,
or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; the validity,
enforceability or collectability of any Notes Obligations; the assets, liabilities, financial condition, results of operations,
business, creditworthiness or legal status of any obligor; or for any failure of any obligor to perform its Notes Obligations under

    112

     

    

 

Section 7.5.         
Notice of Defaults.

 

If a Default or Event of Default occurs
and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail (or in the case of Global Notes,
deliver electronically in accordance with the Applicable Procedures of the Depositary) to each Holder 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 relating to payment of principal
of, premium, if any, or interest on, any Note (including payments pursuant to the redemption or required repurchase provisions
of such Note), the Trustee may withhold the notice if and so long as its board of directors, the executive committee of its board
of directors or a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders.

 

Section 7.6.         
Compensation and Indemnity.

 

(a)                    
The Issuer shall pay to the Trustee from time to time compensation for its services as the Issuer and the Trustee shall
from time to time agree upon in writing. 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 upon request for all reasonable out-of-pocket expenses, disbursements
and advances incurred or made by it, including but not limited to the costs of collection, costs of preparing and reviewing reports,
certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel (in the
case of Canadian counsel, on a solicitor-client, full-indemnity basis) retained by the Trustee in connection with the delivery
of an Opinion of Counsel or otherwise, in addition to the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee’s agents and counsel (and in the case of Canadian counsel,
on a solicitor-client, full-indemnity basis). The Issuer shall indemnify and hold harmless the Trustee (in its individual and trustee
capacities) and its officers, directors, employees, shareholders and agents against any and all loss, liability, claims, action,
suit, cost or expense (including reasonable attorneys’ fees (and in the case of Canadian attorneys, on a solicitor-client,
full-indemnity basis)) of any kind and nature whatsoever incurred by it in connection with the acceptance or administration of
this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including
this Section 7.6) and of defending itself against any claims or liability in connection with the exercise or performance of any
of its powers or duties hereunder or thereunder (whether asserted by any Holder, the Issuer or otherwise). The Trustee shall notify
the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve
the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee may have separate counsel and the Issuer
shall pay the fees and expenses of such counsel (and in the case of Canadian counsel, on a solicitor-client, full-indemnity basis).
The Issuer is not required to reimburse any expense or indemnify against any loss, liability claim, suit, cost or expense incurred
by the Trustee through the Trustee’s own willful misconduct or gross negligence.

 

(b)                    
To secure the Issuer’s payment obligations in this Section 7.6, the Trustee shall have a lien prior to the Notes on
all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, premium
(if any) and interest on particular Notes.

 

(c)                    
The Issuer’s payment obligations pursuant to this Section 7.6 shall survive the discharge of this Indenture and the
resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section
6.1(7) hereof with respect to the Issuer, the expenses are intended to constitute expenses of administration under any Bankruptcy
Law.

 

    113

     

    

 

Section 7.7.         
Replacement of Trustee.

 

(a)                    
A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.7.

 

(b)                    
The Trustee may resign at any time by so notifying the Issuer. The Holders of a majority in outstanding principal amount
of the Notes may remove the Trustee by so notifying the Trustee and the Issuer and may appoint a successor Trustee. The Issuer
may remove the Trustee if: (i) the Trustee fails to comply with Section 7.9 hereof; (ii) the Trustee is adjudged bankrupt or insolvent;
(iii) a Custodian or other public officer takes charge of the Trustee or its property; or (iv) the Trustee otherwise becomes incapable
of acting.

 

(c)                    
If the Trustee resigns or is removed by the Issuer or by the Holders of a majority in outstanding principal amount of the
Notes and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee
for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuer shall promptly appoint
a successor Trustee.

 

(d)                    
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 or deliver electronically a notice of its
succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee,
subject to the lien provided for in Section 7.6 hereof.

 

(e)                    
If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee or the Holders of 10% in outstanding principal amount of the Notes may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

 

(f)                    
If the Trustee fails to comply with Section 7.9 hereof after written notice thereto, the Holders of at least 10% in principal
amount of the then outstanding Notes may petition any court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor Trustee.

 

(g)                    
Notwithstanding the replacement of the Trustee pursuant to this Section 7.7, the Issuer’s obligations under Section
7.6 hereof shall continue for the benefit of the retiring Trustee.

 

Section 7.8.         
Successor Trustee by Merger.

 

(a)                    
If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business
or assets to, another Person, the resulting, surviving or transferee Person without any further act shall be the successor Trustee.

 

    114

     

    

 

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

 

Section 7.9.         
Eligibility; Disqualification.

 

The Trustee shall at all times satisfy the
requirements of Trust Indenture Act Section 310(a) with the same effect as if this Indenture were qualified under the Trust Indenture
Act. There shall at all times be a Trustee hereunder that is a Person organized and doing business under the laws of the U.S. or
of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or
examination by federal or state authorities and that has a combined capital and surplus (together with its Affiliates) of at least
$15 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture
Act Section 310(b) with the same effect as if this Indenture were qualified under the Trust Indenture Act.

 

Section 7.10.     
Preferential Collection of Claims Against Company.

 

The Trustee shall comply with Trust Indenture
Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned
or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated.

 

Section 7.11.     
Collateral Documents; First Lien Intercreditor Agreement.

 

By their acceptance of the Notes, the Holders
hereby authorize and direct the Trustee and Notes Collateral Agent, as the case may be, to execute and deliver the Joinder Agreement
and any other Collateral Documents in which the Trustee or the Notes Collateral Agent, as applicable, is named as a party, including
any Collateral Documents executed on or after the Issue Date. It is hereby expressly acknowledged and agreed that, in doing so,
the Trustee and the Notes Collateral Agent are 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 or any other Collateral Documents,
the Trustee and the Notes Collateral Agent each shall have all of the rights, privileges, benefits, immunities, indemnities and
other protections granted to it under this Indenture (in addition to those that may be granted to it under the terms of such other
agreement or agreements).

Article
VIII

DISCHARGE OF INDENTURE; DEFEASANCE

 

Section 8.1.         
Discharge of Liability on Notes; Defeasance.

 

(a)                    
Subject to Section 8.1(c) hereof, this Indenture, the Note Guarantees and the Collateral Documents will cease to be of further
effect as to all Notes issued hereunder when (i) either (x) all Notes that have been authenticated, except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the
Issuer, have been delivered to the Trustee for cancellation or (y) all Notes that have not been delivered to the Trustee for cancellation
have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable within
one year and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for
the benefit of the Holders, cash in U.S. dollars, Government Securities, or a combination of cash in U.S. dollars and Government
Securities, in amounts as will be sufficient to pay and discharge the principal, premium, if any, and accrued interest to the date
of final maturity or redemption; provided that upon any redemption that occurs prior to the Par Call Date, the amount deposited
shall be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the Redemption
Price calculated as of the date of the notice of redemption, with any deficit as of the Redemption Date (any such amount, the “Redemption
Price Deficit”) only required to be deposited with the Trustee on or prior to the Redemption Date; provided, further,
that any Redemption Price Deficit shall be set forth in an Officer’s Certificate delivered to the Trustee simultaneously
with the deposit of such Redemption Price Deficit that confirms that such Redemption Price Deficit shall be applied toward such
redemption; (ii) no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result
of the deposit other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and
the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which
the Issuer or any Restricted Subsidiary is a party or by which the Issuer or any Restricted Subsidiary is bound, (iii) the Issuer
has paid or caused to be paid all sums then payable by it under this Indenture, and (iv) the Issuer has delivered irrevocable instructions
to the Trustee to apply the deposited money toward the payment of such Notes at Stated Maturity or the Redemption Date, as the
case may be.

 

(b)                    
Subject to Section 8.2 hereof, the Issuer at its option at any time may terminate (i) all its obligations, except as specified
in Section 8.1(c) hereof, under the Notes and this Indenture, the Collateral Documents and all obligations of the Guarantors with
respect to their Note Guarantees (“legal defeasance option”), and after giving effect to such legal defeasance,
any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under
Section 4.2, Section 4.3, Section 4.4, Section 4.5, Section 4.6, Section 4.7 and Section 4.16 hereof, and 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 Section, whether
directly or indirectly, by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such
Section to any other provision herein or in any other document and the operation of Section 6.1(3), Section 6.1(4), Section 6.1(5),
Section 6.1(6), Section 6.1(9) and the events specified in such Sections shall no longer constitute an Event of Default (this clause
(ii) being referred to as the “covenant defeasance option”), but otherwise the remainder of this Indenture and
the Notes shall be unaffected thereby. The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of
its covenant defeasance option. If the Issuer exercises its legal defeasance option or its covenant defeasance option, each Guarantor
shall be released from its obligations with respect to its Note Guarantee as provided in Section 10.10 hereof.

 

    116

     

    

 

If the Issuer exercises its legal defeasance
option, payment of the Notes may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance
option, payment of the Notes may not be accelerated because of an Event of Default specified in Section 6.1(3), Section 6.1(4)
and Section 6.1(5) hereof.

 

Upon satisfaction of the conditions set
forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the
Issuer terminates, on demand of the Issuer (accompanied by an Officer’s Certificate and an Opinion of Counsel, each stating
that all conditions precedent provided in this Indenture relating to the legal defeasance or covenant defeasance, as the case may
be, have been complied with) and at the cost and expense of the Issuer.

 

(c)                    
Notwithstanding the provisions of Section 8.1(a) and Section 8.1(b) hereof, the obligations of the Issuer in Section 2.3,
Section 2.4, Section 2.5, Section 2.6, Section 2.7, Section 2.9, Section 7.6, Section 7.7 hereof, and in this Article VIII shall
survive until the Notes have been paid in full. Thereafter, the following provisions shall survive until otherwise terminated or
discharged hereunder:

 

(1)           
the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on such Notes when
such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.2;

 

(2)           
the Issuer’s obligations concerning issuing temporary Notes, mutilated, destroyed, lost, or stolen Notes and the maintenance
of a register in respect of the Notes;

(1)           
the Issuer shall have deposited or caused to be deposited with the Trustee as trust funds or property in trust for the purpose
of making payment on such Notes an amount of cash or Government Securities as will, together with the income to accrue thereon
and reinvestment thereof, be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of
independent public accountants, to pay, satisfy and discharge the entire principal, interest, if any, premium, if any and any other
sums due to the Stated Maturity or an optional redemption date of the Notes;

 

(2)           
no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens to secure such borrowing);

 

    117

     

    

 

(3)           
the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the
Issuer with the intent of preferring the Holders over its other creditors or with the intent of defeating, hindering, delaying,
or defrauding any of its other creditors or others;

 

(4)           
the Issuer shall have delivered to the Trustee, (a) an Opinion of Counsel acceptable to the Trustee in its reasonable judgment
or an advance tax ruling from the Canada Revenue Agency (or successor agency) to the effect that the Holders of outstanding Notes
will not recognize income, gain or loss for Canadian income tax purposes as a result of such legal defeasance or covenant defeasance,
as the case may be, and will be subject to Canadian federal income tax on the same amounts, in the same manner, and at the same
times as would have been the case if such legal defeasance or covenant defeasance, as the case may be, had not occurred; (b) in
the case of legal defeasance, an Opinion of Counsel acceptable to the Trustee in its reasonable judgment to the effect that (i)
the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the Issue Date,
there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such
Opinion of Counsel will confirm that, the Holders of outstanding 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 on the same amounts, in
the same manner and at the same times as would have been the case if such legal defeasance had not occurred; and (c) in the case
of covenant defeasance, an Opinion of Counsel acceptable to the Trustee in its reasonable judgment to the effect that the Holders
of outstanding 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 in the case if such covenant defeasance had not occurred;

 

(5)           
the Issuer shall have satisfied the Trustee and the Notes Collateral Agent that it has paid, caused to be paid or made provisions
for the payment of all applicable expenses of the Trustee and the Notes Collateral Agent;

 

(6)           
such legal defeasance option or covenant defeasance option will not result in a breach or violation of, or constitute a

is a party or by which the Issuer or any of its Subsidiaries is bound; and

 

(7)           
the Issuer shall have delivered to the Trustee and the Notes Collateral Agent an Officer’s Certificate stating that
all conditions precedent relating to the legal defeasance option or the covenant defeasance option, as the case may be, have been

of which such deposit is made, (b) irrevocable, subject to certain exceptions, and (c) made under the terms of an escrow and/or

Repayment to Company.

 

The Trustee and each Paying Agent shall
promptly turn over to the Issuer upon receipt of an Issuer Order any excess money or securities held by them upon payment of all
the obligations under this Indenture.

 

Subject to any applicable abandoned property
law, the Trustee and each Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal
of, or premium, if any, or interest on the Notes that remains unclaimed for two years (or any such money then held by the Issuer
or any Subsidiary shall be discharged from any trust hereunder), and, thereafter, Holders entitled to the money must look to the
Issuer for payment as unsecured general creditors; provided, however, that, if any Definitive Notes are then outstanding,
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 will not be less than 30 days from the date of such notification or publication,

court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and the Guarantors’
obligations under this Indenture and the affected Notes shall be revived and reinstated as though no money had been deposited pursuant
to this Article VIII until such time as the Trustee or such Paying Agent is permitted to apply all such money or Government
Securities in accordance with this Article VIII; provided that if the Issuer has made any payment in respect of principal
of, premium, if any, or interest on Notes or, as applicable, other amounts because of the reinstatement of its obligations, the

held by the Trustee.

Section 9.2.         
With Consent of Holders.

 

(a)                    
Except as provided in this Section 9.2, the Issuer, the Guarantors and the Trustee with the affirmative votes of the Holders
of at least a majority in principal amount of the Notes represented and voting at a meeting of Holders, or by a resolution in writing
of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or offer to purchase, or exchange offer for, Notes):

 

(1)           
this Indenture, the Notes, the Note Guarantees and the Collateral Documents may each be amended or supplemented; and

 

(2)           
any existing Default or Event of Default or lack of compliance with any provision of this Indenture, the Notes, the Note
Guarantees or the Collateral Documents may be waived.

 

(b)                    
Without the consent of, or a resolution passed by the affirmative votes of or signed by, each Holder affected, an amendment,
supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

 

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

 

(2)           
reduce the principal of any Note or change the time for payment thereof;

 

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

 

(4)           
make any Note payable in a currency other than that stated in the Notes;

 

(5)           
waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, 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 Notes and
a waiver of the payment default that resulted from such acceleration);

 

(6)           
amend the contractual right expressly set forth in this Indenture and the Notes of any Holder to institute suit for the
enforcement of any payment of principal, premium, if any, and interest on such Holders’ Notes on or after the due dates therefor;

 

(7)           
modify or change any provision of this Indenture or the related definitions affecting the ranking of the Notes or any Note
Guarantee in any manner adverse to the Holders;

 

    121

     

    

 

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

 

(9)           
modify these amending provisions.

 

Notwithstanding the foregoing, without the
consent of the Holders of at least 662⁄3% in aggregate principal amount of the Notes then outstanding, no amendment or waiver
may (A) make any change in any Collateral Document or the provisions in this Indenture dealing with Collateral or application of
trust proceeds of the Collateral with the effect of releasing the Liens on all or substantially all of the Collateral which secure
the obligations in respect of the Notes or (B) change or alter the priority of the Liens securing the Notes Obligations in respect
of the Notes in any material portion of the Collateral in any way adverse to the Holders in any material respect, other than, in
each case, as provided under the terms of the Collateral Documents or the First Lien Intercreditor Agreement.

 

Any item of business referred to in this
Indenture requiring the written approval or consent of the Holders may be obtained by means of the affirmative vote of the requisite
Holders represented at a duly constituted meeting of Holders or a resolution in writing of the requisite Holders of Notes then
outstanding.

 

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

 

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

 

Section 9.3.         
Revocation and Effect of Consents.

 

Until an amendment, supplement or waiver
becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note
if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An
amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

 

The Issuers may, but shall not be obligated
to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If
a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their
duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke
any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall
be valid or effective for more than 120 days after such record date unless the consent of the requisite number of Holders has been
obtained.

 

    122

     

    

 

Section 9.4.         
Notation on or Exchange of Notes.

 

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

 

Section 9.5.         
Trustee to Sign Amendments.

 

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

 

Article
X

NOTE GUARANTEES

 

Section 10.1.     
Note Guarantees.

 

Subject to this Article X, each of the Guarantors
hereby, jointly and severally, unconditionally guarantees to each Holder and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, the full
and punctual payment of principal of, premium (if any) and interest on the Notes when due, whether at Stated Maturity, or upon
redemption, required repurchase pursuant to Section 4.5 or Section 4.7 hereof, acceleration or otherwise, and all other monetary
obligations owing by the Issuer under this Indenture (including obligations owing to the Trustee) and the Notes (all the foregoing
being hereinafter collectively called the “Obligations”). The Guarantors further agree that the Obligations
may be extended or renewed, in whole or in part, without notice or further assent from the Guarantors, and that the Guarantors
will remain bound under this Article X notwithstanding any extension or renewal of any Obligation. Failing payment when due of
any amount so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to promptly pay the same.
Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. All payments under each Note Guarantee
will be made in U.S. dollars.

 

    123

     

    

 

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

 

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

 

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

 

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

 

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

 

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

 

    124

     

    

 

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

 

The Note Guarantee issued by any Guarantor
shall be a general senior secured obligation of such Guarantor and shall be pari passu in right of payment with all existing and
future senior Indebtedness of such Guarantor, if any.

 

Section 10.2.     
Limitation on Liability.

 

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

 

Section 10.3.     
Execution and Delivery of Note Guarantee.

 

To evidence its Note Guarantee set forth
in Section 10.1, each Guarantor hereby agrees that this Indenture (or a supplemental indenture substantially in form of Exhibit
D hereof) will be executed on behalf of such Guarantor by one of its Officers.

 

Each Guarantor hereby agrees that its Note
Guarantee set forth in Section 10.1 will remain in full force and effect notwithstanding any absence of a notation of such Note
Guarantee on any Note.

 

If an officer whose signature is on this
Indenture (or a supplemental indenture substantially in form of Exhibit D hereof) no longer holds that office at the time
the Trustee authenticates a Note, the Note Guarantee of such Guarantor shall be valid nevertheless.

 

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

 

In the event that the Issuer or any of its
Restricted Subsidiaries acquires or creates another Restricted Subsidiary after the Issue Date, the Issuer shall comply with the
provisions of Section 4.6 hereof and this Article X, to the extent applicable.

 

    125

     

    

 

Section 10.4.     
Successors and Assigns.

 

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

 

Section 10.5.     
No Waiver.

 

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

 

Section 10.6.     
Right of Contribution.

 

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

 

Section 10.7.     
No Subrogation.

 

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

 

    126

     

    

 

Section 10.8.     
Benefits Acknowledged.

 

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

 

Section 10.9.     
Modification.

 

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

 

Section 10.10. 
Release of Note Guarantees.

 

(a)                    
A Guarantor will be released from its obligations under its Note Guarantee upon the occurrence of any of the following:

 

(1)           
in the event of (i) a sale or other disposition of all or substantially all of the assets of such Guarantor, by way of consolidation,
merger, amalgamation, dividend, distribution or otherwise, to a Person that is not (either before or after giving effect to such
transaction) the Issuer or a Restricted Subsidiary, provided that upon the completion of such sale or other disposition,
such Guarantor ceases to exist, or (ii) a sale or other disposition of the Capital Stock of such Guarantor such that it ceases
to be a Restricted Subsidiary, in the case of each of the foregoing clauses (i) and (ii) to the extent that such sale or other
disposition is permitted under this Indenture;

 

(2)           
the release or discharge of the guarantee by, or direct obligation of, such Guarantor with respect to its obligations under
the First Lien Term Loan Credit Agreement (including as a result of such Guarantor being designated as an “Unrestricted Subsidiary”
under the First Lien Term Loan Credit Agreement), except a discharge or release by or a result of payment under such guarantee
or direct obligation;

 

(3)           
if such Guarantor is designated as an Unrestricted Subsidiary in accordance with the applicable provisions of the 2026 Secured
Notes Indenture, upon the effectiveness of such designation;

upon payment in full in cash of the principal of, accrued and unpaid interest and premium (if any) on, the Notes; or

upon the Issuer exercising its legal defeasance or covenant defeasance option in accordance with Section 8.1(b) hereof or
the Issuer’s obligations under this Indenture otherwise being discharged in accordance with the terms of this Indenture.

 

(b)                    
Upon delivery by the Issuer to the Trustee of an Officer’s Certificate stating that any of the conditions described
in Sections 10.10(a)(1) through (a)(5) has occurred, the Trustee shall execute any supplemental indenture or other documents reasonably
requested by the Issuer in order to evidence the release of any Guarantor from its obligations under its Note Guarantee and this
Indenture.

Agent under this Indenture, the Notes, the Note Guarantees, the First Lien Intercreditor Agreement and the Collateral Documents,
according to the terms hereunder or thereunder, shall be secured as provided in the Collateral Documents, which provide for the

the Issuer and the Guarantors hereby acknowledge and agree that the Notes Collateral Agent holds the Collateral in trust for the
benefit of the Notes Secured Parties and pursuant to the terms of the Collateral Documents and the First Lien Intercreditor Agreement.
Each Holder, by accepting a Note, consents and agrees to the terms of the Collateral Documents (including the provisions providing
for the possession, use, release and foreclosure of Collateral) and the First Lien Intercreditor Agreement as the same may be in
effect or may be amended from time to time in accordance with their terms and this Indenture, and authorizes and directs the Notes
Collateral Agent to enter into the Collateral Documents and the First Lien Intercreditor Agreement on and after the Issue Date
and to perform its obligations and exercise its rights thereunder in accordance therewith. The Issuer shall deliver to the Notes
Collateral Agent copies of all documents required to be filed pursuant to the Collateral Documents, and will do or cause to be

or First Lien Term Loan Obligations, no actions shall be required to be taken with respect to the perfection of the security interests
in the Collateral to the extent such actions are not required to be taken with respect to the First Lien Revolving Credit Obligations
or First Lien Term Loan Obligations, as applicable. Such security interests and Liens will be created under the Collateral Documents
and other security agreements, mortgages, deeds of trust and other instruments and documents. With respect to Collateral constituting
Material Real Property, the Issuer shall cause the Collateral Requirement to be satisfied within 90 days after the Issue Date.

(at the Issuer’s expense) such instruments or releases to evidence the release of any Collateral permitted to be released
pursuant to this Indenture or the Collateral Documents or the First Lien Intercreditor Agreement and shall do or cause to be done
(at the Issuer’s expense) all acts reasonably requested of them to release such Lien as soon as is reasonably practicable.
Neither the Trustee nor the Notes Collateral Agent shall be liable for any such release undertaken in reliance upon any such Officer’s
Certificate or Opinion of Counsel, and notwithstanding any term hereof or in any Collateral Document or in the First Lien Intercreditor
Agreement to the contrary, the Trustee and the Notes Collateral Agent shall not be under any obligation to release any such Lien
and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and until it
receives such Officer’s Certificate and Opinion of Counsel, upon which it shall be entitled to conclusively rely.

Section 11.3.     
Suits to Protect the Collateral.

 

Subject to the provisions of VII and the
Collateral Documents and the First Lien Intercreditor Agreement, the Trustee may or may direct the Notes Collateral Agent to take
all actions it determines in order to:

 

(a)                    
enforce any of the terms of the Collateral Documents; and

 

(b)                    
collect and receive any and all amounts payable in respect of the Notes Obligations hereunder.

 

Subject to the provisions of the Collateral
Documents and the First Lien Intercreditor Agreement, the Trustee and the Notes Collateral Agent, at the Issuer’s sole cost
and expense, shall have power to institute and to maintain such suits and proceedings as the Trustee may determine to prevent any
impairment of the Collateral by any acts which may be unlawful or in violation of any of the Collateral Documents or this Indenture,
and such suits and proceedings as the Trustee may determine to preserve or protect its interests and the interests of the Holders
in the Collateral. Nothing in this Section 11.3 shall be considered to impose any such duty or obligation to act on the part of
the Trustee or the Notes Collateral Agent.

 

Section 11.4.     
Authorization of Receipt of Funds by the Trustee Under the Collateral Documents.

 

Subject to the provisions of the First
Lien Intercreditor Agreement, the Trustee is authorized to receive any funds for the benefit of the Holders distributed under the
Collateral Documents, and to make further distributions of such funds to the Holders according to the provisions of this Indenture.

 

Section 11.5.     
Purchaser Protected.

 

In no event shall any purchaser in good
faith of any property purported to be released hereunder be bound to ascertain the authority of the Notes Collateral Agent or the
Trustee to execute the applicable release or to inquire as to the satisfaction of any conditions required by the provisions hereof
for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee;
nor shall any purchaser or other transferee of any property or rights permitted by this Article XI to be sold be under any obligation
to ascertain or inquire into the authority of the Issuer or the applicable Guarantor to make any such sale or other transfer.

 

    130

     

    

 

Section 11.6.     
Powers Exercisable by Receiver or Trustee.

 

In case the Collateral shall be in the
possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article XI upon the Issuer or a Guarantor
with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument
signed by such 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 XI; and if the Trustee or Notes Collateral Agent shall
be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee
or the Notes Collateral Agent.

 

Section 11.7.     
[Reserved]

 

Section 11.8.     
Notes Collateral Agent.

 

(a)                    
The Issuer and each of the Holders by acceptance of the Notes hereby designates and appoints the Notes Collateral Agent
as its agent under this Indenture, the Collateral Documents and the First Lien Intercreditor Agreement, and the Issuer and each
of the Holders by acceptance of the Notes hereby irrevocably authorizes the Notes Collateral Agent to take such action on its behalf
under the provisions of this Indenture, the Collateral Documents and the First Lien Intercreditor Agreement and to exercise such
powers and perform such duties as are expressly delegated to the Notes Collateral Agent by the terms of this Indenture, the Collateral
Documents and the First Lien Intercreditor Agreement, and consents and agrees to the terms of the First Lien Intercreditor Agreement
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 Notes Collateral Agent agrees to act as such on the express conditions
contained in this Section 11.8. Each Holder agrees that any action taken by the Notes Collateral Agent in accordance with the provision
of this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents, and the exercise by the Notes 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 and the First Lien Intercreditor
Agreement, the duties of the Notes Collateral Agent shall be ministerial and administrative in nature, and the Notes Collateral
Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Collateral Documents and
the First Lien Intercreditor Agreement to which the Notes Collateral Agent is a party, nor shall the Notes Collateral Agent have
or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder or any Grantor, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture, the Collateral Documents and
the First Lien Intercreditor Agreement or otherwise exist against the Notes Collateral Agent. Without limiting the generality of
the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Notes 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.

 

    131

     

    

 

(b)                    
The Notes Collateral Agent may perform any of its duties under this Indenture, the Collateral Documents or the First Lien
Intercreditor Agreement by or through receivers, agents, employees, attorneys-in-fact or with respect to any specified Person,
such Person’s Affiliates, and the respective officers, directors, employees, agents, advisors and attorneys-in-fact of such
Person and its Affiliates (a “Related Person”), and shall be entitled to advice of counsel 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 legal counsel. The Notes Collateral Agent shall not be responsible for the negligence or misconduct
of any receiver, agent, employee, attorney-in-fact or Related Person that it selects as long as such selection was made in good
faith and with due care.

 

(c)                    
None of the Notes Collateral Agent or any of its respective Related Persons shall (i) be liable for any action taken or
omitted to be taken by any of them under or in connection 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 or the First Lien Intercreditor
Agreement 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 Grantor or Affiliate of any Grantor, or any Officer or Related Person thereof, contained in this Indenture,
the Collateral Documents or the First Lien Intercreditor Agreement, or in any certificate, report, statement or other document
referred to or provided for in, or received by the Notes Collateral Agent under or in connection with, this Indenture, the Collateral
Documents or the First Lien Intercreditor Agreement, or the validity, effectiveness, genuineness, enforceability or sufficiency
of this Indenture, the Collateral Documents or the First Lien Intercreditor Agreement, or for any failure of any Grantor or any
other party to this Indenture, the Collateral Documents or the First Lien Intercreditor Agreement to perform its obligations hereunder
or thereunder. None of the Notes Collateral Agent or any of its respective Related Persons shall 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 or the First Lien Intercreditor Agreement or to inspect the properties,
books, or records of any Grantor or any Grantor’s Affiliates.

 

(d)                    
The Notes 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 other Grantor), independent accountants and other experts and advisors selected by the Notes Collateral
Agent. The Notes Collateral Agent shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper
or document. The Notes Collateral Agent shall be fully justified in failing or refusing to take any action under this Indenture,
the Collateral Documents or the First Lien Intercreditor Agreement unless it shall first receive such advice or concurrence of
the Trustee or the Holders of a majority in aggregate principal amount of the Notes as it determines 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 Notes Collateral Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Indenture, the Collateral Documents or the First Lien Intercreditor Agreement
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.

 

    132

     

    

 

(e)                    
The Notes 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 Notes Collateral Agent shall have received written notice from the Trustee or the
Issuer referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice
of default.” The Notes Collateral Agent shall take such action with respect to such Default or Event of Default as may be
requested by the Trustee in accordance with Article VI or the Holders of a majority in aggregate principal amount of the Notes
(subject to this Section 11.8).

 

(f)                    
The Notes Collateral Agent may resign at any time by 30 days’ written notice to the Trustee and the Issuer, such resignation
to be effective upon the acceptance of a successor agent to its appointment as Notes Collateral Agent. If the Notes 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 Notes Collateral Agent (as stated in the notice of resignation),
the Trustee, at the direction of the Holders of a majority of the aggregate principal amount of the Notes then outstanding, may
appoint 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 Notes 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 Notes Collateral Agent, and the term “Notes Collateral
Agent” shall mean such successor collateral agent, and the retiring Notes Collateral Agent’s appointment, powers and
duties as the Notes Collateral Agent shall be terminated. After the retiring Notes Collateral Agent’s resignation hereunder,
the provisions of this Section 11.8 (and Section 7.6) shall continue to inure to its benefit and the retiring Notes 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 Notes Collateral Agent under this Indenture.

 

(g)                    
Computershare Trust Company, N.A. shall initially act as Notes Collateral Agent and shall be authorized to appoint co-Notes
Collateral Agents as necessary in its sole discretion. Except as otherwise explicitly provided herein or in the Collateral Documents
or the First Lien Intercreditor Agreement, neither the Notes Collateral Agent nor any of its respective officers, directors, employees
or agents or other Related Persons shall be liable for failure to demand, collect or 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 Notes Collateral Agent shall
be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Notes 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.

 

    133

     

    

 

(h)                    
The Notes Collateral Agent is authorized and directed to (i) enter into the Collateral Documents to which it is party, whether
executed on or after the Issue Date, (ii) enter into the Joinder Agreement, (iii) make the representations of the Holders set forth
in the Collateral Documents and First Lien Intercreditor Agreement, (iv) bind the Holders on the terms as set forth in the Collateral
Documents and the First Lien Intercreditor Agreement and (v) perform and observe its obligations under the Collateral Documents
and the First Lien Intercreditor Agreement.

 

(i)                    
If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral
or any payments with respect to the Notes Obligations arising under, or relating to, this Indenture, except for any such proceeds
or payments received by the Trustee from the Notes Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from
the Notes Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article VII, the Trustee shall
promptly turn the same over to the Notes Collateral Agent, in kind, and with such endorsements as may be required to negotiate
the same to the Notes Collateral Agent such proceeds to be applied by the Notes Collateral Agent pursuant to the terms of this
Indenture, the Collateral Documents and the First Lien Intercreditor Agreement.

 

(j)                    
The Notes 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 Uniform Commercial Code or the PPSA, as applicable, 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 Notes Collateral Agent thereof and promptly shall deliver such Collateral to the Notes Collateral Agent or otherwise deal with
such Collateral in accordance with the Notes Collateral Agent’s instructions.

 

(k)                    
The Notes 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 any Grantor or is cared for, protected, or insured or has been encumbered, or that the Notes 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 of the Grantor’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 Notes Collateral Agent pursuant to this Indenture, any Collateral Document or the First Lien Intercreditor
Agreement 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 Notes Collateral Agent shall have any
duty or obligation to monitor the condition, financial or otherwise, of any Grantor.

 

(l)                    
If the Issuer or any Guarantor (i) incurs any First Lien Obligations at any time when no applicable intercreditor agreement
is in effect or at any time when Indebtedness constituting First Lien Obligations entitled to the benefit of an existing intercreditor
agreement is concurrently retired, and (ii) delivers to the Notes Collateral Agent an Officer’s Certificate so stating and
requesting the Notes Collateral Agent to enter into an intercreditor agreement (on substantially the same terms as the First Lien
Intercreditor Agreement) in favor of a designated agent or representative for the holders of the First Lien Obligations so incurred,
together with an Opinion of Counsel, the Holders acknowledge and agree that the Notes 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 legal fees and
expenses of the Notes Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations
thereunder; provided that neither an Officer’s Certificate nor an Opinion of Counsel shall be required in connection
with the Joinder Agreement to be entered into by the Notes Collateral Agent on the Issue Date.

 

    134

     

    

 

(m)                    
No provision of this Indenture, the First Lien Intercreditor Agreement or any Collateral Document shall require the Notes
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 (or the Trustee in the case of the Notes Collateral Agent) unless it shall have received indemnity
satisfactory to the Notes Collateral Agent and the Trustee against potential costs and liabilities incurred by the Notes Collateral
Agent relating thereto. Notwithstanding anything to the contrary contained in this Indenture, the First Lien Intercreditor Agreement
or the Collateral Documents, in the event the Notes 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 Notes 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 Notes Collateral Agent has determined that the Notes 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. The Notes
Collateral Agent shall at any time be entitled to cease taking any action described in this clause if it no longer reasonably deems
any indemnity, security or undertaking from the Issuer or the Holders to be sufficient.

 

(n)                    
The Notes 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 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 Notes Collateral Agent may agree in writing with the Issuer (and money held in trust by the Notes 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 as to matters of law 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 Notes Collateral Agent shall not be construed to impose duties to act.

 

(o)                    
Neither the Notes Collateral Agent nor the Trustee shall be liable for delays or failures in performance resulting from
acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics,
governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes
or other disasters. Neither the Notes Collateral Agent nor the Trustee shall be liable for any indirect, special, punitive, incidental
or consequential damages (included but not limited to lost profits) whatsoever, even if it has been informed of the likelihood
thereof and regardless of the form of action.

 

    135

     

    

 

(p)                    
The Notes Collateral Agent does not assume any responsibility for any failure or delay in performance or any breach by the
Issuer or any other Grantor under this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents. The Notes
Collateral Agent shall not be responsible to the Holders or any other Person for any recitals, statements, information, representations
or warranties contained in this Indenture, the Collateral Documents, the First Lien Intercreditor Agreement, any Notes or in any
certificate, report, statement, or other document referred to or provided for in, or received by the Notes Collateral Agent under
or in connection with, this Indenture, the First Lien Intercreditor Agreement or any Collateral Document; the execution, validity,
genuineness, effectiveness or enforceability of this Indenture, the First Lien Intercreditor Agreement and any Collateral Documents
of any other party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral,
or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; the validity,
enforceability or collectability of any Notes Obligations; the assets, liabilities, financial condition, results of operations,
business, creditworthiness or legal status of any obligor; or for any failure of any obligor to perform its Notes Obligations under
this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents. The Notes Collateral Agent shall have no obligation
to any Holder or any other Person to ascertain or inquire into the existence of any Default or Event of Default, the observance
or performance by any obligor of any terms of this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents,
or the satisfaction of any conditions precedent contained in this Indenture, the First Lien Intercreditor Agreement and any Collateral
Documents. The Notes Collateral Agent shall not be required to initiate or conduct any litigation or collection or other proceeding
under this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents unless expressly set forth hereunder
or thereunder. The Notes Collateral Agent shall have the right at any time to seek instructions from the Holders with respect to
the administration of this Indenture, the Collateral Documents and the First Lien Intercreditor Agreement.

 

(q)                    
The parties hereto and the Holders hereby agree and acknowledge that neither the Notes Collateral Agent nor the Trustee
shall assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations,
requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs
(including but not limited to, any remediation, corrective action, response, removal or remedial action, or investigation, operations
and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant
to any environmental law as a result of this Indenture, the First Lien Intercreditor Agreement, the Collateral Documents or any
actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the
exercise of its rights under this Indenture, the First Lien Intercreditor Agreement and the Collateral Documents, the Notes Collateral
Agent may hold or obtain indicia of ownership primarily to protect the security interest of the Notes Collateral Agent in the Collateral
and that any such actions taken by the Notes Collateral Agent shall not be construed as or otherwise constitute any participation
in the management of such Collateral. In the event that the Notes Collateral Agent or the Trustee is required to acquire title
to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or
trust obligation for the benefit of another, which in the Notes Collateral Agent or the Trustee’s sole discretion may cause
the Notes Collateral Agent or the Trustee to be considered an “owner or operator” under the provisions of the Comprehensive
Environmental Response, Compensation and Liability Act (“CERCLA”), 42 U.S.C. §9601, et seq., or otherwise
cause the Notes Collateral Agent or the Trustee to incur liability under CERCLA or any other federal, state, provincial or local
law, the Notes Collateral Agent and the Trustee each reserves the right, instead of taking such action, to either resign as the
Notes Collateral Agent or the Trustee or arrange for the transfer of the title or control of the asset to a court-appointed receiver.
Neither the Notes Collateral Agent nor the Trustee shall be liable to the Issuer, the Guarantors or any other Person for any environmental
claims or contribution actions under any federal, state, provincial or local law, rule or regulation by reason of the Notes Collateral
Agent or the Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to the discharge,
release or threatened release of hazardous materials into the environment. If at any time it is necessary or advisable for property
to be possessed, owned, operated or managed by any Person (including the Notes Collateral Agent or the Trustee) other than the
Issuer or the Guarantors, Holders of a majority in aggregate principal amount of the then outstanding Notes shall direct the Notes
Collateral Agent or the Trustee to appoint an appropriately qualified Person (excluding the Notes Collateral Agent or the Trustee)
who they shall designate to possess, own, operate or manage, as the case may be, the property.

 

    136

     

    

 

(r)                    
Upon the receipt by the Notes Collateral Agent of a written request of the Issuer signed by an Officer (a “Collateral
Document Order”), the Notes Collateral Agent is hereby authorized to execute and enter into, and shall execute and enter
into, without the further consent of any Holder or the Trustee, any Collateral Document or amendment or supplement thereto to be
executed after the Issue Date. Such Collateral Document Order shall (i) state that it is being delivered to the Notes Collateral
Agent pursuant to, and is a Collateral Document Order referred to in, this Section 11.8(r), and (ii) instruct the Notes Collateral
Agent to execute and enter into such Collateral Document. Any such execution of a Collateral Document shall be at the direction
and expense of the Issuer, upon delivery to the Notes Collateral Agent of an Officer’s Certificate and Opinion of Counsel
stating that all conditions precedent to the execution and delivery of the Collateral Document have been satisfied. The Holders,
by their acceptance of the Notes, hereby authorize and direct the Notes Collateral Agent to execute such Collateral Documents.

 

(s)                    
Subject to the provisions of the applicable Collateral Documents and the First Lien Intercreditor Agreement, each Holder,
by acceptance of the Notes, agrees that the Notes Collateral Agent shall execute and deliver the First Lien Intercreditor Agreement
and the Collateral Documents to which it is a party and all agreements, documents and instruments incidental thereto, and act in
accordance with the terms thereof. For the avoidance of doubt, the Notes Collateral Agent shall have no discretion under this Indenture,
the First Lien Intercreditor Agreement or the Collateral Documents and shall not be required to make or give any determination,
consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount
of the then outstanding Notes or the Trustee, as applicable.

 

    137

     

    

 

(t)                    
After the occurrence and during the continuance of an Event of Default, the Trustee, acting at the direction of the Holders
of a majority of the aggregate principal amount of the Notes then outstanding, may direct the Notes Collateral Agent in connection
with any action required or permitted by this Indenture, the Collateral Documents or the First Lien Intercreditor Agreement.

 

(u)                    
The Notes Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed
under the Collateral Documents or the First Lien Intercreditor Agreement and to the extent not prohibited under the First Lien
Intercreditor Agreement, for turnover to the Trustee to make further distributions of such funds to itself, the Trustee and the
Holders in accordance with the provisions of Section 6.10 and the other provisions of this Indenture.

 

(v)                    
In each case that the Notes Collateral Agent may or is required hereunder or under any Collateral Document or the First
Lien Intercreditor Agreement to take any action (an “Action”), including without limitation to make any determination,
to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under
any Collateral Document or the First Lien Intercreditor Agreement, the Notes Collateral Agent may seek direction from the Holders
of a majority in aggregate principal amount of the then outstanding Notes. The Notes 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 Notes 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 Notes Collateral Agent shall be entitled
to refrain from such Action unless and until the Notes Collateral Agent shall have received direction from the Holders of a majority
in aggregate principal amount of the then outstanding Notes, and the Notes Collateral Agent shall not incur liability to any Person
by reason of so refraining.

 

(w)                    
Notwithstanding anything to the contrary in this Indenture or in any Collateral Document or the First Lien Intercreditor
Agreement, in no event shall the Notes 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 or the First Lien Intercreditor Agreement (including without limitation
the filing or continuation of any UCC or PPSA financing or continuation statements or similar documents or instruments), nor shall
the Notes Collateral Agent or the Trustee be responsible for, and neither the Notes Collateral Agent nor the Trustee makes any
representation regarding, the validity, effectiveness or priority of any of the Collateral Documents or the First Lien Intercreditor
Agreement or the security interests or Liens intended to be created thereby.

 

(x)                    
Before the Notes Collateral Agent acts or refrains from acting in each case at the request or direction of the Issuer or
the Guarantors, it may require an Officer’s Certificate and an Opinion of Counsel, which shall conform to the provisions
of Section 12.4. The Notes 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.

 

    138

     

    

 

 

(y)     Notwithstanding anything to the contrary contained herein, the Notes Collateral Agent shall act pursuant to the instructions
of the Holders and the Trustee solely with respect to the Collateral Documents and the Collateral.

    140 

     

    

 

Section 12.5.     
When Notes Disregarded.

 

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 or by any Person
directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer shall be disregarded
and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying
on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be
so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

 

Section 12.6.     
Legal Holidays.

 

A “Legal Holiday” is
a day that is not a Business Day. Notwithstanding any other provisions of this Indenture, the Notes, the Collateral Documents or
the Note Guarantees, if a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal
Holiday, and no interest shall accrue for the intervening period. If a record date is a Legal Holiday, the record date shall not
be affected.

 

Section 12.7.     
Governing Law; Submission to Jurisdiction.

 

(a)     THIS
INDENTURE, THE NOTES AND THE NOTE GUARANTEES ARE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

 

(b)     The
Issuer, each of the Guarantors and the Trustee agree that any suit, action or proceeding arising out of or based upon this Indenture,
the Notes or the Note Guarantees may be instituted in any State or U.S. federal court located in The City of New York and County
of New York, and waives any objection that such party may now or hereafter have to the laying of venue of any such proceeding,
and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. Nothing in this Indenture,
the Notes or the Collateral Documents shall affect any right that the Trustee, the Notes Collateral Agent or any Holder may otherwise
have to bring any suit, action or proceeding relating to this Indenture, the Notes, any Collateral Document, the Guarantees or
the transactions contemplated hereby against the Issuer or any Guarantor or its properties in the courts of any jurisdiction.

 

    141 

     

    

 

(c)     The
Issuer has appointed Corporation Services Company, located at 1180 Avenue of the Americas, Suite 210, New York, New York 10036-8401,
United States, and each Guarantor incorporated, formed or otherwise organized outside of the United States (the “Foreign
Guarantors”) has appointed GFL Environmental USA Inc., located at 26999 Central Park Blvd., Suite 200, Southfield, Michigan
48076, as their respective authorized agents (each, an “Authorized Agent”) upon whom process may be served
in any such action arising out of or based on this Indenture, the Notes, the Collateral Documents, the Note Guarantees or the
transactions contemplated hereby or thereby that may be instituted in any federal or state court in the Borough of Manhattan in
the City of New York, New York, expressly consents to the jurisdiction of any such court in respect of any such action, and waives
any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable.
The Issuer represents and warrants that its Authorized Agent has agreed to act as such agent for service of process and agrees
to take any and all action, including the filing of any and all documents and instruments, which may be necessary to continue
such appointment in full force and effect as stated above. Service of process upon the Issuer’s Authorized Agent and written
notice of such service to the Issuer shall be deemed, in every respect, effective service of process upon the Issuer. Service
of process upon a Foreign Guarantor’s Authorized Agent and written notice of such service to such Foreign Guarantor shall
be deemed, in every respect, effective service of process upon such Foreign Guarantor.

 

Section 12.8.     
Waiver of Jury Trial.

 

EACH OF THE ISSUER, THE GUARANTORS, THE
TRUSTEE AND THE NOTES COLLATERAL AGENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

 

Section 12.9.     
Force Majeure.

 

In no event shall the Trustee or the Notes
Collateral Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out
of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents,
acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss
or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee
shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon
as practicable under the circumstances.

 

Section 12.10. 
No Personal Liability of Directors, Officers, Employees and Shareholders.

 

No past, present or future director, officer,
employee, incorporator, member, partner, trustee, beneficiary or shareholder of the Issuer, any Guarantor or any of their Affiliates,
as such, will have any liability for any obligations of the Issuer or any Guarantor under the Notes, this Indenture, or the Note
Guarantees, the Collateral Documents, or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes.

 

    142 

     

    

 

Section 12.11. 
Successors.

 

All agreements of the Issuer and (except
as otherwise provided in Section 10.9 hereof) the Guarantors in this Indenture, the Notes, the Collateral Documents and the Note
Guarantees shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successors.

 

Section 12.12. 
Multiple Originals; Counterparts.

 

The parties may sign any number of copies
of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy
is enough to prove this Indenture. This Indenture may be executed in multiple counterparts which, when taken together, shall constitute
one instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute
effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for
all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures
for all purposes. The words “execution,” “signed,” “signature,” “delivery,” and
words of like import in or relating to this Indenture or any document to be signed in connection with this Indenture shall be deemed
to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal
effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping
system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

 

Section 12.13. 
Severability.

 

In case any provision in this Indenture
or in the Notes or the Collateral Documents or the Note Guarantees is invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions will not in any way be affected or impaired thereby.

 

Section 12.14. 
Table of Contents; Headings.

 

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

 

Section 12.15. 
No Adverse Interpretation of Other Agreements.

 

This Indenture may not be used to interpret
any other indenture, loan or debt agreement of the Issuer or its Subsidiaries or of any other Person. Any such indenture, loan
or debt agreement may not be used to interpret this Indenture.

 

Section 12.16. 
Acts of Holders.

 

(a)     Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed
by such Holders in person or by agents duly appointed in writing, and may be given or obtained in connection with a purchase of,
or tender offer or exchange offer for, outstanding Notes; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to
the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred
to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument
or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Issuer if made in the manner provided in this Section 12.6.

 

    143 

     

    

 

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

 

(c)     Notwithstanding anything to the contrary contained in this Section 12.6, the principal amount and serial numbers of Notes
held by any Holder, and the date of holding the same, shall be proved by the register of the Notes maintained by the Registrar
as provided in Section 2.3.

 

(d)     If
the Issuer shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act,
the Issuer may, at its option, by or pursuant to a resolution of its Board of Directors, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Issuer shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection
therewith or the date of the most recent list of Holders forwarded to the Trustee prior to such solicitation pursuant to Section
2.5 and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record
at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of
the requisite proportion of the then outstanding Notes have authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the then outstanding Notes shall be computed as of such
record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the
record date.

 

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

 

    144 

     

    

 

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

 

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

 

Section 12.17. 
Indemnification for Non-U.S. Dollar Currency Judgments.

 

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

 

(b)    The provisions of this Section 12.17 shall apply irrespective of any indulgence granted to the Issuer or any Guarantor from
time to time and shall continue in full force and effect notwithstanding any payment by or on behalf of the Issuer or any Guarantor,
and any amount due from the Issuer under this Section 12.17 will be due as a separate payment and shall not be affected by any
judgment obtained or claims made for any other sums due under or in respect of this Indenture.

 

Section 12.18. 
Interest Act (Canada).

 

Solely for purposes of disclosure under
the Interest Act (Canada), the yearly rate of interest to which interest is calculated under a Note for any period in any calendar
year (the “Calculation Period”) is equivalent to the rate payable under a Note in respect of the Calculation
Period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator of
which is the actual number of days in the Calculation Period.

[BACK OF NOTE]

GFL ENVIRONMENTAL INC.

3.500% SENIOR SECURED NOTES DUE 2028

 

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

 

1.          Interest.
GFL Environmental Inc., a corporation organized under the laws of the Province of Ontario (such Person, and its respective successors
and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay
interest on the outstanding principal amount of this Note at the rate of 3.500% per annum from December 21, 20201
until maturity. The Issuer will pay interest semi-annually in arrears on March 1 and September 1 of each year, or if any such day
is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”); provided,
that the first Interest Payment Date will be September 1, 2021. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing
Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and
the next succeeding Interest Payment Date, interest will accrue from such next succeeding Interest Payment Date. The Issuer will
pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal
and premium, if any, at the rate then in effect; it will pay, to the extent lawful, interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods)
from time to time on demand at the same rate as on overdue principal. Interest will be computed on the basis of a 360-day year
of twelve 30-day months. Solely for purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which
interest is calculated under a Note for any period in any calendar year (the “Calculation Period”) is equivalent
to the rate payable under a Note in respect of the Calculation Period multiplied by a fraction the numerator of which is the actual
number of days in such calendar year and the denominator of which is the actual number of days in the Calculation Period.

 

2.         Method
of Payment. The Issuer will pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders
of Notes at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes
are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.11 of the Indenture
with respect to Defaulted Interest. The Notes will be payable as to principal, premium, if any, and interest by, in the case of
Notes represented by the Global Notes, wire transfer of immediately available funds to the accounts specified by The Depository
Trust Company or its nominee and, in the case of Definitive Notes, wire transfer of immediately available funds to the accounts
specified by the Holders of the Notes or, if no such account is specified, by mailing a check to each such Holder at its address
set forth in the register of Holders. Such payment will be in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts. Holders must surrender their Notes to the Paying Agent to collect
payments of principal and premium, if any.

(2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion
of such payments of interest accrued as of the Redemption Date) that would be due if the Notes matured on the Par Call Date, discounted
