(f) the Indenture Trustee, on behalf of Holders of Trust Notes — Series 2019-A, hereby agrees, without any further action being required by the Holders of Trust Notes — Series 2019-A, the Trust or TCPL, that the right of the Holders of Trust Notes — Series 2019-A to receive interest thereon in respect of such Deferral Date shall automatically be set off against the obligation of the Holders of Trust Notes — Series 2019-A to pay the cash subscription price for the Deferral Preferred Shares to the Trust corresponding to the applicable Deferral Event Subscription Proceeds, and the Holders of Trust Notes — Series 2019-A shall not be required to pay such subscription prices in cash; and

(h) TCPL shall promptly create, issue and (subject to Section 4.3) distribute such number of TCPL Deferral Preferred Shares (including fractional shares, if applicable), with a stated issue price of $1,000 per share, as are issuable pursuant to the Deferral Event Subscription;

(i) TCPL shall transfer and deliver to each Holder of Trust Notes — Series 2019-A who has not been identified by the Trust as an Ineligible Person pursuant to paragraph (c), from among the TCPL Deferral Preferred Shares issued in accordance with paragraph (h), a number of TCPL Deferral Preferred Shares (including fractional shares, if applicable) calculated in respect of the Holder by dividing (x) the interest amount payable in respect of such Holder’s Trust Notes — Series 2019-A on the applicable Deferral Date, by (y) the stated issue amount of the Deferral Preferred Share issued by TCPL; and

(j) TCPL shall transfer and deliver to the Indenture Trustee, in respect of each Holder of Trust Notes — Series 2019-A who has been identified by the Trust as an Ineligible Person pursuant to paragraph (c), from among the TCPL Deferral Preferred Shares issued in accordance with clause (h), a number of TCPL Deferral Preferred Shares (including

Any exercise of such discretionary rights, powers and authorities by the Indenture Trustee shall be final, conclusive and binding upon all Persons. For greater certainty, with respect to the Trust Notes — Series 2019-A and the TCPL Deferral Preferred Shares, the Indenture Trustee shall have only those duties as are set out specifically in this Agreement. The Indenture Trustee, in exercising its rights, powers, duties and authorities hereunder, shall act honestly and in good faith with a view to the best interests of the Holders and shall exercise the care, diligence and skill that a reasonably prudent trustee, nominee and agent would exercise in comparable circumstances. The Indenture Trustee shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof; nor shall the Indenture Trustee be required to take any notice of, or to do or to take any act, action or proceeding as a result of any default or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notice shall specify the default or breach desired to be brought to the attention of the Indenture Trustee and in the absence of such notice the Indenture Trustee may for all purposes of this Agreement conclusively assume that no default or breach has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained in this Agreement.

5.2 No Conflict of Interest

The Indenture Trustee represents to the Trust and TCPL that, at the date of execution and delivery of this Agreement, there exists no material conflict of interest in the role of the Indenture Trustee as a fiduciary hereunder. The Indenture Trustee shall, within 90 days after it becomes aware that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Article 8. If, notwithstanding the foregoing provisions of this Section 5.2, the Indenture Trustee has such a material conflict of interest, the validity and enforceability of this Agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Indenture Trustee contravenes the foregoing provisions of this Section 5.2, any interested party may apply to the Superior Court of Justice (Ontario) for an order that the Indenture Trustee be replaced as bare trustee and nominee under this Agreement.

5.3 Dealings with Transfer Agents, Registrars and the Clearing Agency

In addition to and without limiting the Trust Indenture, the Trust and TCPL severally and irrevocably authorize the Indenture Trustee, from time to time, to:

(b) if applicable, consult, communicate and otherwise deal with the Clearing Agency; and

(c) requisition, from time to time, from such registrar or transfer agent or the Clearing Agency any information readily available from the records maintained by any such entity which the Indenture Trustee may reasonably require for the discharge of its duties and

responsibilities under the Trust Notes — Series 2019-A Provisions, the TCPL Deferral Preferred Share Provisions and this Agreement.

Notwithstanding any other provision of this Agreement, and in addition to and without limiting the Trust Indenture, the Indenture Trustee shall only be required to exercise any or all of the rights, duties, powers or authorities vested in it by this Agreement at the written request, order or direction of any Holder upon such Holder furnishing to the Indenture Trustee reasonable funds, security and indemnity satisfactory to the Indenture Trustee, acting reasonably, against the costs, expenses and liabilities that may be incurred by the Indenture Trustee therein or thereby, provided that no Holder will be obligated to furnish to the Indenture Trustee any such funding, security or indemnity in connection with the exercise, but not the enforcement, by the Indenture Trustee of any of its rights, duties, powers and authorities vested in it by this Agreement. None of the provisions contained in this Agreement shall require the Indenture Trustee to expend or risk its own funds or otherwise incur financial liability in the exercise of any of its rights, powers, duties or authorities under this Agreement nor limits the Indenture Trustee, acting reasonably, from requesting an indemnity, before any exercise or enforcement of rights. In addition, the Indenture Trustee shall disburse funds only to the extent that funds have been deposited with it.

5.6 Actions by Holders

No Holder shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this Agreement for the purpose of enforcing any of its rights or for the execution of any trust, power or obligation hereunder unless the Holder has requested in writing the Indenture Trustee to take or institute such action, suit or proceeding and, subject to Section 5.5, furnished the Indenture Trustee with the funding, security and indemnity referred to in Section 5.5, and the Indenture Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Holder shall be entitled to take proceedings in any court of competent jurisdiction, it being understood and intended that no one or more Holders shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by any such action, or to enforce any right hereunder, except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be exercised and all proceedings at law shall be instituted, had and maintained by the Indenture Trustee, except only as herein provided, and in any event for the benefit of all Holders.

the exercise of its rights, powers, duties and authorities hereunder and such notices, statutory declarations, certificates, opinions, reports or other papers or documents comply with this Agreement, nor shall the Indenture Trustee be responsible for relying on the accuracy of the information contained in any such document provided it honestly and in good faith believes such information to be correct. The Indenture Trustee shall not be responsible or liable in any manner for the sufficiency, genuineness, correctness or validity of any security deposited with it.

The Indenture Trustee shall retain the right not to act and shall not be held liable for refusing to act unless it receives documentation which complies with the terms of this Agreement.

The parties acknowledge that federal, provincial and/or state legislation in Canada or the United States that address the protection of individuals’ personal information (collectively, “Privacy Laws”) may apply to obligations and activities under this Agreement. Despite any other provision of this Agreement, no party shall take or direct any action that would contravene, or cause any other party to contravene, applicable Privacy Laws. The Indenture Trustee shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Indenture Trustee agrees: (a) to have a designated chief privacy officer; (b) to maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry; (c) to use personal information solely for the purposes of providing its services under or ancillary to this Agreement and not to use it for any other purpose except with the consent of or direction from the Trust and TCPL or the individual involved; (d) not to sell or otherwise improperly disclose personal information to any third party; and (e) to employ administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification.

5.20 Compliance with Anti-Money Laundering Legislation

The Indenture Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Indenture Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. The Trust hereby agrees that if any account to be opened, or interest to be held, by the Indenture Trustee in connection with this Agreement, for or to the credit of the Trust, is intended to be used by or on behalf of a third party, the Trust will complete and execute forthwith a declaration in the Indenture Trustee’s prescribed form as to the particulars of such third party.

ARTICLE 7
INDEMNIFICATION AND LIMITATION OF LIABILITY

7.1 Indemnification of Indenture Trustee

In addition to and without limiting the Trust Indenture, the Trust and TCPL jointly and severally agree to indemnify and hold harmless the Indenture Trustee and each of its directors, officers, employees, representatives and agents appointed and acting in accordance with this Agreement (collectively,

the “Indemnified Parties”) against all claims, losses, damages, costs, penalties, fines, taxes, assessments of additional taxes, interest or penalties or other governmental charges, including the withholding or deduction or the failure to withhold or deduct same, any liability for failure to obtain proper certifications or to properly report to government authorities, and reasonable expenses (including reasonable expenses of the Indenture Trustee’s legal counsel) which, without fraud, negligence or wilful misconduct on the part of such Indemnified Party, are paid, incurred or suffered by the Indemnified Party by reason of or as a result of the Indenture Trustee’s acceptance or administration of the trust, its compliance with its duties set forth in this Agreement, or with any written or oral instructions delivered to the Indenture Trustee by the Trust or TCPL pursuant hereto (collectively, “Claims” and individually, a “Claim”). In no case will the Trust or TCPL be liable under this indemnity for any Claim if such Claim is incurred or suffered by reason of or as a result of the fraud, negligence or wilful misconduct of an Indemnified Party and unless the Trust and TCPL shall be notified by the Indenture Trustee of the written assertion of a Claim promptly after any of the Indemnified Parties shall have received any such written assertion of a Claim or shall have been served with a summons or other first legal process giving information as to the nature and basis of the Claim, provided that a failure or delay to so notify the Trust and TCPL shall not diminish the liability of the Trust and TCPL hereunder except to the extent that the Trust and TCPL are materially prejudiced by such failure or delay. Subject to (ii) below, the Trust and TCPL shall be entitled to participate at their own expense in the defence and, if the Trust or TCPL so elect at any time after receipt of such notice, any of them may assume the defence of any suit brought to enforce any such Claim. The Indenture Trustee shall have the right to employ separate counsel in any such suit and participate in the defence thereof but the fees and expenses of such counsel shall be at the expense of the Indenture Trustee unless: (i) the employment of such counsel has been authorized by the Trust or TCPL, such authorization not to be unreasonably withheld; or (ii) the named parties to any such suit include both the Indenture Trustee and the Trust or TCPL and the Indenture Trustee shall have been advised by counsel acceptable to the Trust and TCPL that there may be one or more legal defences available to the Indenture Trustee that are different from or in addition to those available to the Trust or TCPL and that an actual or potential conflict of interest exists (in which case the Trust and TCPL shall not have the right to assume the defence of such suit on behalf of the Indenture Trustee but shall be liable to pay the reasonable fees and expenses of counsel for the Indenture Trustee). This provision shall survive the resignation or removal of the Indenture Trustee or the termination of this Agreement.

7.2 Limitation of Liability

Without limiting the Trust Indenture, the Indenture Trustee shall not be held liable for any loss which may occur by reason of insolvency or termination of TCPL, the Trust or any Holder, as the case may be, or early termination of any investment under Section 5.10 or depreciation of the value of any part of the Series 2019-A Trust Estate or any loss incurred on any investment of funds pursuant to this Agreement, except to the extent that such loss is attributable to fraud, negligence or wilful misconduct on the part of the Indenture Trustee.

8.2 Removal of Indenture Trustee

The Indenture Trustee, or any Indenture Trustee hereafter appointed, may be removed in accordance with the Trust Indenture: (i) with cause or if the Indenture Trustee at any time ceases to be a resident of Canada for the purposes of the Tax Act by written instrument executed by the Trust and TCPL; or (ii) with or without cause by the Holders of Trust Notes — Series 2019-A pursuant to an Extraordinary Resolution and, if any TCPL Deferral Preferred Shares are outstanding, by the affirmative vote of Holders of the TCPL Deferral Preferred Shares passed in accordance with the TCPL Deferral Preferred Share Provisions (as though the removal were an amendment to the TCPL Deferral Preferred Share Provisions), in all cases, at any time on 60 days’ prior written notice, which notice shall be delivered to the Indenture Trustee so removed and to the successor Indenture Trustee in accordance with the Trust Indenture.

8.3 Successor Indenture Trustee

Any successor Indenture Trustee appointed in accordance with the Trust Indenture shall execute, acknowledge and deliver to the Trust and TCPL and to its predecessor Indenture Trustee an instrument accepting such appointment hereunder and under the Trust Indenture. Subject to the Trust Indenture, thereupon, the resignation or removal of the predecessor Indenture Trustee shall become effective and such successor Indenture Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as Indenture Trustee in accordance with the Trust Indenture. However, on the written request of the Trust and TCPL or of the successor Indenture Trustee, the Indenture Trustee ceasing to act shall, upon payment of any amounts then due to it pursuant to the provisions of this Agreement, execute and deliver an instrument transferring to such successor Indenture Trustee all the rights and powers of the Indenture Trustee so ceasing to act. In addition to and without limiting the Trust Indenture, upon the request of any such successor Indenture Trustee, the Trust and TCPL, such predecessor Indenture Trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor Indenture Trustee all such rights and powers. Without limiting the Trust Indenture, any company into which the Indenture Trustee may be merged or with which it may be consolidated or amalgamated, or any company resulting or continuing from any merger, consolidation or amalgamation to which the Indenture Trustee is a party or any company to which the Indenture Trustee may transfer all or substantially all of its corporate trust business, shall be a successor Indenture Trustee under this Agreement, without the execution or filing of any paper or further act on the part of any of the parties hereto.

8.4 Notice of Successor Indenture Trustee

Upon acceptance of appointment by a successor Indenture Trustee as provided in this Agreement, the Trust and TCPL shall cause to be mailed notice of the succession of such Indenture Trustee under this Agreement to each registered Holder.

SCHEDULE A

TCPL DEFERRAL PREFERRED SHARE PROVISIONS

FIRST PREFERRED SHARES, SERIES-[·] DEFERRAL

There is hereby authorized and created a series of First Preferred Shares designated as the “First Preferred Shares, Series-[·] Deferral” (hereinafter referred to as the “Deferral Preferred Shares, Series-[·]”) consisting of up to [·] Deferral Preferred Shares. The Deferral Preferred Shares, Series-[·] may be issued in whole or in fractional shares, as provided below, and shall, in addition to the rights, privileges, restrictions and conditions attaching to the First Preferred Shares as a class (collectively and respectively, the “First Preferred Shares Class Provisions” and the “First Preferred Shares”), carry and be subject to the following rights, privileges, restrictions and conditions (collectively, the “Deferral Preferred Shares, Series-[·] Provisions”):

Dividends

1. The holders of the Deferral Preferred Shares, Series-[·] shall be entitled to receive and the Corporation shall pay thereon, as and when declared by the board of directors out of the monies of the Corporation properly applicable to the payment of dividends, on each Dividend Payment Date, fixed cumulative preferential cash dividends equal to the quotient obtained by dividing: (x) the product obtained by multiplying $1,000 by a rate per annum equal to the rate of interest payable by the Trust on the Trust Notes as of the Issue Date, by (y) four; provided that if an event (including a redemption) shall occur that results in accrued and unpaid dividends for a partial Dividend Period becoming payable, the dividend payable for any partial Dividend Periods shall be equal to the product obtained by multiplying the amount in (x) above by a fraction, the numerator of which is the actual number of days attributable to the partial Dividend Period and the denominator of which is 365, subject in each case to any applicable withholding tax. If on any Dividend Payment Date the dividend payable on such date is not paid in full on all of the Deferral Preferred Shares, Series-[·] then issued and outstanding, such dividend or the unpaid part thereof shall be paid on a subsequent date or dates to be determined by the board of directors on which the Corporation shall have sufficient monies properly applicable, under the provisions of any applicable law and under the provisions of any trust indenture securing bonds, debentures or other securities of the Corporation, to the payment of the same. The holders of the Deferral Preferred Shares, Series-[·] shall not be entitled to any dividends other than or in excess of the cumulative preferential cash dividends hereinbefore provided. Payment shall be made by electronic funds transfer or by cheque of or on behalf of the Corporation payable in lawful money of the United States (less any tax required to be deducted) and payment thereof shall satisfy such dividends.

Liquidation, Dissolution or Winding-Up

2. In the event of the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or any other distribution of assets of the Corporation among its shareholders for the purpose of winding-up its affairs, the holders of the Deferral Preferred Shares, Series-[·] in accordance with the First Preferred Shares Class Provisions, shall be entitled to receive the amount of $1,000 (less any amount that may have been returned to the holders of Deferral Preferred Shares, Series-[·] as a return of capital), together with an amount equal to all accrued and unpaid dividends thereon, which amount for such purposes shall be calculated as if such dividends were accruing for the period from the expiration of the last Dividend Period for which dividends thereon have been paid up to the date of such event, subject to any applicable withholding tax, the whole before any amount shall be paid or any property or assets of the Corporation

shall be distributed to the holders of the common shares or to the holders of any other shares ranking junior to the Deferral Preferred Shares, Series-[·]. After payment to the holders of the Deferral Preferred Shares, Series-[·] of the amount so payable to them they shall not be entitled to share in any other distribution of the property or assets of the Corporation.

Voting Rights

3. The holders of the Deferral Preferred Shares, Series-[·] shall not be entitled to receive notice of or attend any meeting of the shareholders of the Corporation or to vote at any such meeting unless and until the Corporation from time to time shall fail to pay in the aggregate six quarterly dividends on the Deferral Preferred Shares, Series-[·] on the dates on which the same should be paid according to the terms thereof, whether or not consecutive and whether or not dividends have been declared and whether or not there are any moneys of the Corporation properly applicable to the payment of dividends. Thereafter each holder of Deferral Preferred Shares, Series-[·] shall be entitled to receive notice of all meetings of shareholders and attend thereat and shall be entitled, at any and all such meetings, to one vote for each Deferral Preferred Share, Series-[·] held and shall continue to be entitled to notice and so to attend and vote until such time as all arrears of dividends on any outstanding Deferral Preferred Shares, Series-[·] shall have been paid, whereupon the rights of holders of Deferral Preferred Shares, Series-[·] to receive notice of meetings and to attend thereat and vote in respect of such Deferral Preferred Shares, Series-[·] shall cease unless and until six quarterly dividends on the Deferral Preferred Shares, Series-[·] shall again be in arrears and unpaid, whereupon the holders of the Deferral Preferred Shares, Series-[·] shall again have the right to receive notice and to attend and vote as above provided and so on from time to time.

Purchase for Cancellation

4. The Corporation may, at any time and from time to time, subject to the provisions of the Canada Business Corporations Act, and the provisions below under “Redemption” and “Restrictions on Payment of Dividends and Reduction of Junior Capital”, purchase for cancellation (if obtainable), in the manner provided in the First Preferred Shares Class Provisions, the whole or any part of the Deferral Preferred Shares, Series-[·] outstanding from time to time at any price, subject to any applicable withholding tax.

Redemption

5. Subject to the provisions of the Canada Business Corporations Act and the provisions below under “Restrictions on Payment of Dividends and Reduction of Junior Capital” the Corporation may redeem all, or from time to time any part, of the outstanding Deferral Preferred Shares, Series-[·], without the consent of the holders of the Deferral Preferred Shares, Series-[·], on not more than 60 days and not less than 30 days prior notice, at any time by the payment of an amount in cash for each such share so redeemed of $1,000 per share (such price being hereinafter referred to as the “Redemption Price”) together with an amount equal to all accrued and unpaid dividends thereon, subject to any applicable withholding tax, which amount for such purpose shall be calculated as if such dividends were accruing for the period from the expiration of the last Dividend Period for which dividends thereon have been paid up to the date of such redemption.
