For each holder of Publicly Offered Preferred Units, the Income allocated to such holder will be an amount calculated by multiplying the aggregate Income allocated to all holders of Publicly Offered Preferred Units pursuant to this Section 4.8.1.1 by a fraction, the numerator of which is the sum of the distributions on Publicly Offered Preferred Units received by such holder with respect to such fiscal year and the denominator of which is the aggregate amount of the distributions made by the Partnership to all holders of Publicly Offered Preferred Units with respect to such fiscal year; and

- 3 -

4.8.1.2     Second, any Income for Canadian Tax Purposes remaining after the allocation pursuant to Section 4.8.1.1 will be allocated to each Partner in an amount calculated by multiplying such remaining Income for Canadian Tax Purposes by a fraction, the numerator of which is the sum of the distributions received by such Partner with respect to such fiscal year (other than distributions received by such Partner on Publicly Offered Preferred Units) and the denominator of which is the aggregate amount of the distributions (other than distributions on Publicly Offered Preferred Units) made by the Partnership with respect to such fiscal year, provided that the numerator and denominator will not include any distributions on the Preferred Units that are in satisfaction of accrued distributions on the Preferred Units that were not paid in a previous fiscal year of the Partnership (excluding for this purpose distributions or accrued distributions on Publicly Offered Preferred Units) where the Managing General Partner determines that the inclusion of such distributions would result in a Preferred Unitholder being allocated more income than it would have if the distributions were paid in the fiscal year of the Partnership in which they were accrued.

Generally, the source and character of items of income allocated to a Partner for Canadian Tax Purposes with respect to a fiscal year of the Partnership will be the same source and character as the distributions received by such Partner with respect to such fiscal year.

4. Section 4.8.2 of the Agreement is hereby deleted in its entirety and replaced with the following:

4.8.2        If, with respect to a given fiscal year, no distribution is made by the Partnership or the Partnership has a Loss for Canadian Tax Purposes, one quarter of the income, or loss, as the case may be, for purposes of the Income Tax Act of the Partnership for such fiscal year, will be allocated to the Partners of record at the end of each Quarter ending in such fiscal year as follows: (i) to the Preferred Unitholders in respect of Preferred Units (excluding for this purpose Publicly Offered Preferred Units) held by them on each such date, such amount of the Income for Canadian Tax Purposes or Loss for Canadian Tax Purposes, as the case may be, as the Managing General Partner determines is reasonable in the circumstances having regard to such factors as the Managing General Partner considers to be relevant, including, the relative Capital Amount of the Preferred Units as compared to all other Units and the relative fair market value of the Preferred Units as compared to all other Units, and (ii) to the Partners other than in respect of Preferred Units the remaining amount of the Income for Canadian Tax Purposes or Loss for Canadian Tax Purposes, as the case may be, pro rata to their respective Percentage Interests at each such date. To such end, any Person who was a Partner at any time during such fiscal year but who has disposed of all of such Person’s Partnership Interests before the last day of that fiscal year may be deemed to be a Partner on the last day of such fiscal year for the purposes of subsection 96(1) of the Income Tax Act. Generally, the source and character of such income or losses so allocated to a Partner for Canadian Tax Purposes at the end of each Quarter will be the same source and character as the income or loss earned or incurred by the Partnership in such Quarter. For greater certainty, where this Section 4.8.2 applies in respect of a given fiscal year, holders of Publicly Offered Preferred Units shall not be allocated an Income or Loss for Canadian Tax Purposes for such fiscal year.

5. Section 13.1 of the Agreement is hereby deleted in its entirety and shall be of no further force or effect.

6. Section 13.7 of the Agreement is hereby deleted in its entirety and replaced with the following:

2. Distributions

2.1           Cumulative Preferential Distributions

The holders of the then Outstanding Series 19 Preferred Limited Partnership Units (the “Holders”) shall be entitled to receive, and the Partnership shall pay thereon, as and when declared by the Managing General Partner, out of moneys of the Partnership legally available for distributions under Bermuda law and without regard to the income of the Partnership, cumulative preferential cash distributions (the “Series 19 Distributions”) payable quarterly at the rates and times herein provided by cheque at par in lawful money of Canada at any branch in Canada of the Partnership’s bankers for the time being or by any other reasonable means the Partnership deems desirable.

(a) During the Initial Fixed Rate Period, the Series 19 Distributions will be payable quarterly on the last day of March, June, September and December of each year (each, a “Distribution Payment Date”) at the Initial Fixed Distribution Rate. The initial Series 19 Distribution will be payable on September 30, 2026 and will be an amount in cash equal to C$0.1339 per Series 19 Preferred Limited Partnership Unit, less any tax required to be deducted and withheld.

(b) During each Subsequent Fixed Rate Period, Series 19 Distributions payable on the Series 19 Preferred Limited Partnership Units will be in an annual amount per unit determined by multiplying the Annual Fixed Distribution Rate applicable to such Subsequent Fixed Rate Period by C$25.00, less any tax required to be deducted and withheld, and shall be payable quarterly on each Distribution Payment Date during such Subsequent Fixed Rate Period.

(c) In respect of each Subsequent Fixed Rate Period, the Partnership will, during such Subsequent Fixed Rate Period calculate on each Fixed Rate Calculation Date the Annual Fixed Distribution Rate for such Subsequent Fixed Rate Period and will give written notice thereof to the Holders. Each such determination by the Partnership of the Annual Fixed Distribution Rate will, in the absence of manifest error, be final and binding upon the Partnership and upon all Holders of Series 19 Preferred Limited Partnership Units.

(d) If on any Distribution Payment Date, the Series 19 Distributions accrued to such date are not paid in full on all of the Series 19 Preferred Limited Partnership Units then Outstanding, such Series 19 Distributions, or the unpaid part thereof, shall be paid on a subsequent date or dates determined by the Managing General Partner on which the Partnership shall have sufficient monies legally available for such Series 19 Distributions under Bermuda law.

Notwithstanding the foregoing, any distribution cheque may be delivered by the Partnership to a Holder at his/her address as aforesaid. The posting or delivery of such cheque or the payment of the Series 19 Distributions by any other reasonable means on or before the date on which such distribution is to be paid to a Holder shall be deemed to be payment and shall satisfy and discharge all liabilities for the payment of such Series 19 Distributions to the extent of the sum represented thereby (plus the amount of any tax required to be deducted and withheld as aforesaid and remitted to the proper tax authority) unless, if applicable, such cheque is not paid on due presentation. Subject to applicable law, distributions which are represented by a cheque which has not been presented to the Partnership’s bankers for payment or that otherwise remain unclaimed for a period of two years from the date on which they were declared to be payable shall be forfeited to the Partnership.

2.2           Distribution for Other than a Full Distribution Period

3. Rights on Liquidation

4. Redemption at the Option of the Partnership

The Partnership may not redeem any of the Series 19 Preferred Limited Partnership Units prior to September 30, 2031. On September 30, 2031 and on September 30 every five years thereafter (each, a “Series 19 Reclassification Date”), the Partnership may, subject to applicable law, the solvency requirements under Bermuda law and to the provisions described under Section 6 below, upon giving notice as hereinafter provided (which notice shall be irrevocable but may be conditional in the Managing General Partner’s discretion on one or more conditions precedent, which will be set forth in the notice of redemption, and the redemption date specified in such notice may be delayed until such time as any or all of such conditions have been satisfied or revoked by the Managing General Partner if it determines that such conditions will not be satisfied), at its option, without the consent of Holders redeem all, or any part, of the then Outstanding Series 19 Preferred Limited Partnership Units by the payment of an amount in cash for each Series 19 Preferred Limited Partnership Unit so redeemed equal to C$25.00 per Series 19 Preferred Limited Partnership Unit, together with all accrued and unpaid Series 19 Distributions up to but excluding the date of payment or distribution (less any tax required to be deducted and withheld by the Partnership) (the “Redemption Price”).

If less than all of the then Outstanding Series 19 Preferred Limited Partnership Units are at any time to be redeemed, then the particular Series 19 Preferred Limited Partnership Units to be redeemed shall be selected on a pro rata basis disregarding fractions or, if the Series 19 Preferred Limited Partnership Units are at such time listed on such exchange, with the consent of the Toronto Stock Exchange, in such manner as the Managing General Partner in its sole discretion may, by resolution determine.

A-6

The Partnership shall give notice in writing not less than 25 days nor more than 60 days prior to the applicable Series 19 Reclassification Date of its intention to redeem such Series 19 Preferred Limited Partnership Units to each person who at the date of giving such notice is the Holder of Series 19 Preferred Limited Partnership Units to be redeemed. If such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if applicable, will state that, in the Managing General Partner’s discretion, the redemption date specified in such notice may be delayed until such time as any or all such conditions will be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions will not have been satisfied by the redemption date, or by the redemption date as so delayed. Any such notice shall be validly and effectively given on the date on which it is sent and such notice shall be given and sent by posting the same in a postage paid envelope addressed to each Holder of Series 19 Preferred Limited Partnership Units to be redeemed at the last address of such Holder as it appears on the securities register of the Partnership, or in the case of joint Holders, to the address of that one whose name appears first in the securities register of the Partnership as one of such joint Holders or, in the event of the address of any Holder not so appearing, then to the address of such Holder last known to the Partnership, provided that the accidental failure or omission to give any such notices as aforesaid to one or more of such Holders shall not affect the validity of the redemption as to the other Holders to be redeemed. Such notice shall set out the number of such Series 19 Preferred Limited Partnership Units held by the person to whom it is addressed which are to be redeemed and the Redemption Price and shall also set out the date on which the redemption is to take place. On and after the date so specified for redemption, the Partnership shall pay or cause to be paid to the Holders to be redeemed the Redemption Price on presentation and surrender, at any place within Canada designated by such notice, of the certificate or certificates for such Series 19 Preferred Limited Partnership Units so called for redemption, subject to the provisions of Section 17. Such payment (less any tax required to be deducted and withheld by the Partnership) shall be made by cheque payable at par at any branch in Canada of the Partnership’s bankers for the time being or by any other reasonable means the Partnership deems desirable and shall be a full and complete discharge of the Partnership’s obligation to pay the Redemption Price owed to the Holders of Series 19 Preferred Limited Partnership Units so called for redemption unless the cheque is not honoured when presented for payment. From and after the date specified in any such notice, the Series 19 Preferred Limited Partnership Units called for redemption shall cease to be entitled to Series 19 Distributions and the Holders thereof shall not be entitled to exercise any of the rights of unitholders in respect thereof, except to receive the Redemption Price therefor, provided that if payment of the Redemption Price shall not be duly made by the Partnership on or before the redemption date, the Partnership shall forthwith thereafter return the Holder’s deposited unit certificate or certificates to the Holder. At any time after notice of redemption is given as aforesaid, the Partnership shall have the right to deposit the Redemption Price of any or all Series 19 Preferred Limited Partnership Units called for redemption (less any tax required to be deducted and withheld by the Partnership), or such part thereof as at the time of deposit has not been claimed by the Holders entitled thereto, with any chartered bank or banks or with any trust company or trust companies in Canada named in the notice of redemption to the credit of a special account or accounts in trust for the respective Holders of such units, to be paid to them respectively upon surrender to such bank or banks or trust company or trust companies of the certificate or certificates representing the same, subject to the provisions of Section 17. Upon such deposit or deposits being made, such units shall be deemed to be redeemed on the redemption date specified in the notice of redemption. After the Partnership has made a deposit as aforesaid with respect to any units, the Holders thereof shall not, from and after the redemption date, be entitled to exercise any of the rights of unitholders in respect thereof and the rights of the Holders thereof shall be limited to receiving a proportion of the amounts so deposited applicable to such units, without interest. Any interest allowed on such deposit shall belong to the Partnership. Subject to applicable law, redemption monies that are represented by a cheque which has not been presented to the Partnership’s bankers for payment or that otherwise remain unclaimed (including monies held in deposit as provided for above) for a period of two years from the date specified for redemption shall be forfeited to the Partnership.

5. Reclassification of Series 19 Preferred Limited Partnership Units

5.1           Reclassification into Series 20 Preferred Limited Partnership Units at the Option of the Holder

(a) Holders of Series 19 Preferred Limited Partnership Units will have the right, at their option, on each Series 19 Reclassification Date, to reclassify, subject to the applicable law and the terms and provisions hereof, all or any part of the then Outstanding Series 19 Preferred Limited Partnership Units registered in the name of the Holder into Series 20 Preferred Limited Partnership Units on the basis of one (1) Series 20 Preferred Limited Partnership Unit for each Series 19 Preferred Limited Partnership Unit. The Partnership will provide written notice not less than 25 and not more than 60 days prior to the applicable Series 19 Reclassification Date to the Holders of the reclassification privilege provided for herein (the “Reclassification Privilege”). Such notice shall (i) set out the Series 19 Reclassification Date, and (ii) include instructions to such Holders as to the method by which such Reclassification Privilege may be exercised, as described in Section 5.3. At least 25 days prior to each Series 19 Reclassification Date, the Partnership will provide to the Holders written notice of the Floating Quarterly Distribution Rate applicable to the Series 20 Preferred Limited Partnership Units for the next succeeding Quarterly Floating Rate Period and the Annual Fixed Distribution Rate applicable to the Series 19 Preferred Limited Partnership Units for the next succeeding Subsequent Fixed Rate Period, in each case as determined by the Partnership.

A-8

(b) If the Partnership gives notice as provided in Section 4 to the Holders of the redemption of all the Series 19 Preferred Limited Partnership Units, the Partnership will not be required to give notice as provided in this Section 5.1 to the Holders of the Floating Quarterly Distribution Rate, Annual Fixed Distribution Rate or Reclassification Privilege and the right of any Holder of Series 19 Preferred Limited Partnership Units to reclassify such Series 19 Preferred Limited Partnership Units as herein provided will cease and terminate in that event.

(c) Holders of Series 19 Preferred Limited Partnership Units shall not be entitled to reclassify their units into Series 20 Preferred Limited Partnership Units on a Series 19 Reclassification Date if the Partnership determines that there would remain Outstanding on the Series 19 Reclassification Date less than 1,000,000 Series 20 Preferred Limited Partnership Units after taking into account all Series 19 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 20 Preferred Limited Partnership Units has been provided and all Series 20 Preferred Limited Partnership Units in respect of which a notice for reclassification into Series 19 Preferred Limited Partnership Units has been provided. The Partnership will give written notice thereof to all affected Holders of Series 19 Preferred Limited Partnership Units at least seven (7) days prior to the applicable Series 19 Reclassification Date and, subject to the provisions of Section 17, will issue and deliver, or cause to be delivered, prior to such Series 19 Reclassification Date, at the expense of the Partnership, to such Holders of Series 19 Preferred Limited Partnership Units, who have surrendered for reclassification any endorsed certificate or certificates representing Series 19 Preferred Limited Partnership Units, new certificates representing the Series 19 Preferred Limited Partnership Units represented by any certificate or certificates surrendered as aforesaid.

A-9

5.2           Automatic Reclassification

If the Partnership determines that there would remain Outstanding on a Series 19 Reclassification Date less than 1,000,000 Series 19 Preferred Limited Partnership Units after taking into account all Series 19 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 20 Preferred Limited Partnership Units has been provided and all Series 20 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 19 Preferred Limited Partnership Units has been provided, then, all, but not part, of the remaining Outstanding Series 19 Preferred Limited Partnership Units will automatically be reclassified into Series 20 Preferred Limited Partnership Units on the basis of one (1) Series 20 Preferred Limited Partnership Unit for each Series 19 Preferred Limited Partnership Unit on the applicable Series 19 Reclassification Date. The Partnership shall give notice in writing thereof to the Holders of such remaining Series 19 Preferred Limited Partnership Units at least seven (7) days prior to the Series 19 Reclassification Date.

5.3           Manner of Reclassification

(a) Subject to the provisions of Section 17, the Reclassification Privilege may be exercised by notice in writing (an “Election Notice”) given not later than 5:00 p.m. (Toronto time) on the 15^th day preceding the applicable Series 19 Reclassification Date during usual business hours at any principal transfer office of the Transfer Agent, or such other place or places in Canada as the Partnership may agree, accompanied by (1) payment or evidence of payment of the tax (if any) payable as provided in this Section 5.3; and (2) the certificate or certificates representing the Series 19 Preferred Limited Partnership Units in respect of which the Holder thereof desires to exercise the Reclassification Privilege with the notice of reclassification on the back thereof or other appropriate notice of reclassification duly endorsed by the Holder, or his or her attorney duly authorized in writing, in which Election Notice such Holder may also elect to reclassify part only of the Series 19 Preferred Limited Partnership Units represented by such certificate or certificates not theretofore called for redemption in which event the Partnership will issue and deliver or cause to be delivered to such Holder, at the expense of the Partnership, a new certificate representing the Series 19 Preferred Limited Partnership Units represented by such certificate or certificates that have not been reclassified. Each Election Notice will be irrevocable once received by the Partnership.

A-10

(b) If the Partnership does not receive an Election Notice from a Holder of Series 19 Preferred Limited Partnership Units during the notice period therefor, then the Series 19 Preferred Limited Partnership Units shall be deemed not to have been reclassified (except in the case of an automatic reclassification pursuant to Section 5.2).

(c) Subject to the provisions of Section 17, in the event the Partnership is required to reclassify all remaining Outstanding Series 19 Preferred Limited Partnership Units into Series 20 Preferred Limited Partnership Units on the applicable Series 19 Reclassification Date as provided for in Section 5.2, the Series 19 Preferred Limited Partnership Units in respect of which the Holders have not previously elected to reclassify will be reclassified on the Series 19 Reclassification Date into Series 20 Preferred Limited Partnership Units and the Holders thereof will be deemed to be Holders of Series 20 Preferred Limited Partnership Units at 5:00 p.m. (Toronto time) on the Series 19 Reclassification Date and will be entitled, upon surrender during usual business hours at any principal transfer office of the Transfer Agent, or such other place or places in Canada as the Partnership may agree, of the certificate or certificates representing Series 19 Preferred Limited Partnership Units not previously provided for reclassification, to receive a certificate or certificates representing the same number of Series 20 Preferred Limited Partnership Units in the manner and subject to the terms and provisions as provided in this Section 5.3.

A-11

(d) Subject to the provisions of Section 17, as promptly as practicable after the Series 19 Reclassification Date, the Partnership will issue and deliver, or cause to be delivered to or upon the written order of the Holder of the Series 19 Preferred Limited Partnership Units so reclassified in accordance with this Section 5, a certificate or certificates, issued in the name of, or in such name or names as may be directed by, such Holder representing the number of fully-paid and non-assessable Series 20 Preferred Limited Partnership Units and the number of remaining Series 19 Preferred Limited Partnership Units, if any, to which such Holder is entitled. Such reclassification will be deemed to have been made at 5:00 p.m. (Toronto time) on the Series 19 Reclassification Date, so that the rights of the Holder of such Series 19 Preferred Limited Partnership Units as the Holder thereof will cease at such time and the person or persons entitled to receive the Series 20 Preferred Limited Partnership Units upon such reclassification will be treated for all purposes as having become the Holder or Holders of record of such Series 20 Preferred Limited Partnership Units at such time.

(e) The Holder of any Series 19 Preferred Limited Partnership Unit on the record date for any Series 19 Distributions declared payable on such unit will be entitled to such distributions notwithstanding that such unit is reclassified into a Series 20 Preferred Limited Partnership Unit after such record date and on or before the date of the payment of such distribution.

(f) Subject to the provisions of Section 17, the issuance of certificates for the Series 20 Preferred Limited Partnership Units upon the reclassification of Series 19 Preferred Limited Partnership Units will be made without charge to the reclassifying Holders for any fee in respect of the issuance of such certificates or the Series 20 Preferred Limited Partnership Units represented thereby; provided, however, that the Partnership will not be required to pay any tax that may be imposed upon such Holder as a result of the reclassification or the issuance of such certificate representing such Series 20 Preferred Limited Partnership Units or any security transfer taxes, and the Partnership will not be required to issue or deliver a certificate or certificates in a name or names other than that of the Holder of the Series 20 Preferred Limited Partnership Units reclassified unless the person or persons requesting the issuance thereof has paid to the Partnership the amount of any such security transfer tax or has established to the satisfaction of the Partnership that such tax has been paid.

A-12

5.4           Status of Reclassified Series 19 Preferred Limited Partnership Units

The reclassification of Series 19 Preferred Limited Partnership Units into Series 20 Preferred Limited Partnership Units shall not give rise to a redemption or cancellation of such Preferred Units.

5.5           Right Not to Deliver Series 19 Preferred Limited Partnership Units

On the exercise of the Reclassification Privilege by a Holder, the Partnership reserves the right not to reclassify the Series 19 Preferred Limited Partnership Units held by any Ineligible Person.

Any such notice shall be validly and effectively given on the date on which it is sent and such notice shall be given and sent by posting the same in a postage paid envelope addressed to each Holder of Series 20 Preferred Limited Partnership Units to be redeemed at the last address of such Holder as it appears on the securities register of the Partnership, or in the case of joint Holders, to the address of that one whose name appears first in the securities register of the Partnership as one of such joint Holders or, in the event of the address of any Holder not so appearing, then to the address of such Holder last known to the Partnership, provided that the accidental failure or omission to give any such notices as aforesaid to one or more of such Holders shall not affect the validity of the redemption as to the other Holders to be redeemed. Such notice shall set out the number of such Series 20 Preferred Limited Partnership Units held by the person to whom it is addressed which are to be redeemed and the Redemption Price and shall also set out the date on which the redemption is to take place. On and after the date so specified for redemption, the Partnership shall pay or cause to be paid to the Holders to be redeemed the Redemption Price on presentation and surrender, at any place within Canada designated by such notice, of the certificate or certificates for such Series 20 Preferred Limited Partnership Units so called for redemption, subject to the provisions of Section 17. Such payment (less any tax required to be deducted and withheld by the Partnership) shall be made by cheque payable at par at any branch in Canada of the Partnership’s bankers for the time being or by any other reasonable means the Partnership deems desirable and shall be a full and complete discharge of the Partnership’s obligation to pay the Redemption Price owed to the Holders of Series 20 Preferred Limited Partnership Units so called for redemption unless the cheque is not honoured when presented for payment. From and after the date specified in any such notice, the Series 20 Preferred Limited Partnership Units called for redemption shall cease to be entitled to Series 20 Distributions and the Holders thereof shall not be entitled to exercise any of the rights of unitholders in respect thereof, except to receive the Redemption Price therefor, provided that if payment of the Redemption Price shall not be duly made by the Partnership on or before the redemption date, the Partnership shall forthwith thereafter return the Holder’s deposited unit certificate or certificates to the Holder.

Upon such deposit or deposits being made, such units shall be deemed to be redeemed on the redemption date specified in the notice of redemption. After the Partnership has made a deposit as aforesaid with respect to any units, the Holders thereof shall not, from and after the redemption date, be entitled to exercise any of the rights of unitholders in respect thereof and the rights of the Holders thereof shall be limited to receiving a proportion of the amounts so deposited applicable to such units, without interest.
