are in satisfaction of accrued distributions on the Preferred Units that were not paid in a previous fiscal year of the Partnership where the 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.

Number and Designation of and Rights, Privileges, Restrictions and Conditions

Attaching to the Cumulative Class A Preferred Limited Partnership Units, Series 1

The first series of Class A Preferred Limited Partnership Units of the Partnership shall consist of 5,000,000 preferred limited partnership interests designated as Cumulative Class A Preferred Limited Partnership Units, Series 1 (the “Series 1 Preferred Limited Partnership Units”) and, in addition to the rights, privileges, restrictions and conditions attaching to the Class A Preferred Limited Partnership Units as a class, shall have attached thereto the following rights, privileges, restrictions and conditions (the “Series 1 Preferred Limited Partnership Unit Provisions”):

1. Consideration for Issue

The consideration for the issue of each Series 1 Preferred Limited Partnership Unit shall be C$25.00 or its equivalent in property or past services.

2. Distributions

2.1 Cumulative Preferential Distributions

The holders of the then Outstanding Series 1 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 properly applicable to the payment of distributions and without regard to the income of the Partnership, cumulative preferential cash distributions (the “Series 1 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 1 Distributions will be payable quarterly on or before 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 1 Distribution will be payable on or before June 30, 2015 and will be an amount in cash equal to C$0.3390 per Series 1 Preferred Limited

Partnership Unit less any tax required to be deducted and withheld. On each Distribution Payment Date during the Initial Fixed Rate Period, (other than June 30, 2015) the Series 1 Distribution will be equal to C$0.28125 per unit.

(b) During each Subsequent Fixed Rate Period, Series 1 Distributions payable on the Series 1 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, on the Fixed Rate Calculation Date, 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 1 Preferred Limited Partnership Units.

(d) If on any Distribution Payment Date, the Series 1 Distributions accrued to such date are not paid in full on all of the Series 1 Preferred Limited Partnership Units then Outstanding, such Series 1 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 properly applicable to the payment of such Series 1 Distributions.

(e) The Holders shall not be entitled to any distributions other than or in excess of the Series 1 Distributions.

(f) The Record Date for the payment of Series 1 Distributions will be the last Business Day of the calendar month prior to the calendar month during which a Distribution Payment Date falls, or such other record date if any, as may be fixed by the Managing General Partner.

Series 1 Distributions shall (except in case of redemption or reclassification in which case payment of Series 1 Distributions shall be made on surrender of the certificate representing the Series 1 Preferred Limited Partnership Units to be redeemed or reclassified) be paid by (i) posting in a postage paid envelope addressed to each Holder 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, a cheque for such Series 1 Distributions (less any tax required to be deducted and withheld) payable to the order of such Holder or, in the case of joint Holders, to the order of all such Holders failing written instructions from them to the contrary or (ii) by any other reasonable means the Partnership deems desirable. 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 1 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 Distributions to the extent of the sum represented thereby (plus the amount of any tax required to be deducted and withheld as aforesaid) 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

Subject to the Section 2.1, for any period that is less than a full Distribution Period, with respect to any Series 1 Preferred Limited Partnership Unit (i) that is issued, redeemed, reclassified or purchased during such Distribution Period or (ii) in respect of which assets of the Partnership are distributed to the Holders thereof pursuant to Section 3, the Holders shall be entitled to receive, and the Partnership shall pay thereon, if, as and when declared by the Managing General Partner, out of moneys of the Partnership properly applicable to the payment of distributions and without regard to the income of the Partnership, Series 1 Distributions as follows:

(a) in respect of the period beginning on and including the date of initial issue of the Series 1 Preferred Limited Partnership Units up to and including June 30, 2015 (the “Initial Distribution Period”), a distribution in an amount per Series 1 Preferred Limited Partnership Units equal to the amount obtained (rounded to four decimal places) where C$1.125 is multiplied by a fraction, the numerator of which is the number of calendar days from but excluding the date of issue of the Series 1 Preferred Limited Partnership Units up to and including June 30, 2015 and the denominator of which is 365, less any tax required to be deducted and withheld. The Series 1 Distribution payable for the Initial Distribution Period, payable as of June 30, 2015, as calculated by this method shall be C$0.3390 per Series 1 Preferred Limited Partnership Units;

(b) in respect of any period other than the Initial Distribution Period that is less than a full Distribution Period, a distribution in an amount per Series 1 Preferred Limited Partnership Unit equal to the amount obtained (rounded to four decimal places) when the product of the Annual Fixed Distribution Rate and C$25.00 is multiplied by a fraction, the numerator of which is the number of calendar days elapsed in the relevant period and the denominator of which is 365, less any tax required to be deducted and withheld.

3. Rights on Liquidation

In the event of the liquidation, dissolution or winding-up of the Partnership, whether voluntary or involuntary, or any other distribution of assets of the Partnership among its unitholders for the purpose of winding-up its affairs, unless the Partnership is continued under the election to reconstitute and continue the Partnership pursuant to Section 16.2 of the Agreement, the Holders shall be entitled to receive C$25.00 per Series 1 Preferred Limited Partnership Unit held by them, together with all accrued (whether or not declared) and unpaid Series 1 Distributions up to but excluding the date of payment or distribution (less any tax required to be deducted and withheld by the Partnership), before any amounts shall be paid or any assets of the Partnership distributed to the holders of any Junior Securities. Upon payment of such amounts, the Holders shall not be entitled to share in any further distribution of the assets of the Partnership.

4. Redemption at the Option of the Partnership

The Partnership may not redeem any of the Series 1 Preferred Limited Partnership Units prior to June 30, 2020. On June 30, 2020 and on June 30 every five years thereafter (each, a “Series 1 Reclassification Date”), the Partnership may, subject to applicable law and to the provisions described under Section 6 below, upon giving notice as hereinafter provided, at its option, without the consent of the Holders redeem all, or any part, of the then Outstanding Series 1 Preferred Limited Partnership Units by the payment of an amount in cash for each Series 1 Preferred Limited Partnership Unit so redeemed equal to C$25.00 per Series 1 Preferred Limited Partnership Unit, together with all accrued and unpaid Series 1 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 1 Preferred Limited Partnership Units are at any time to be redeemed, then the particular Series 1 Preferred Limited Partnership Units to be redeemed shall be selected on a pro rata basis disregarding fractions or, if the Series 1 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.

The Partnership shall give notice in writing not less than 25 days nor more than 60 days prior to the applicable Series 1 Reclassification Date of its intention to redeem such Series 1 Preferred Limited Partnership Units to each person who at the date of giving such notice is the Holder of Series 1 Preferred Limited Partnership Units to be redeemed. 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 1 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 1 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 1 Preferred Limited Partnership Units so called for redemption. Such payment 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 1 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 1 Preferred Limited Partnership Units called for redemption shall cease to be entitled to Series 1 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 1 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. 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 1 Preferred Limited Partnership Units

5.1 Reclassification into Series 2 Preferred Limited Partnership Units at the Option of the Holder

(a) Holders of Series 1 Preferred Limited Partnership Units will have the right, at their option, on each Series 1 Reclassification Date, to reclassify, subject to the applicable law and the terms and provisions hereof, all or any part of the then Outstanding Series 1 Preferred Limited Partnership Units registered in the name of the Holder into Series 2 Preferred Limited Partnership Units on the basis of one (1) Series 2 Preferred Limited Partnership Unit for each Series 1 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 1 Reclassification Date to the Holders of the reclassification privilege provided for herein (the “Reclassification Privilege”). Such notice shall (i) set out the Series 1 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. On the 30th day prior to the first day of a Subsequent Fixed Rate Period, the Partnership will provide to the Holders written notice of the Floating Quarterly Distribution Rate applicable to the Series 2 Preferred Limited Partnership Units for the next succeeding Quarterly Floating Rate Period and the Annual Fixed Distribution Rate applicable to the Series 1 Preferred Limited Partnership Units for the next succeeding Subsequent Fixed Rate Period, in each case as determined by the Partnership.

(b) If the Partnership gives notice as provided in Section 4 to the Holders of the redemption of all the Series 1 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 1 Preferred Limited Partnership Units to reclassify such Series 1 Preferred Limited Partnership Units as herein provided will cease and terminate in that event.

(c) Holders of Series 1 Preferred Limited Partnership Units shall not be entitled to reclassify their units into Series 2 Preferred Limited Partnership Units on a Series 1 Reclassification Date if the Partnership determines that there would remain Outstanding on the Series 1 Reclassification Date less than 1,000,000 Series 2 Preferred Limited Partnership Units after taking into account all Series 1 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 2 Preferred Limited Partnership Units has been provided and all Series 2 Preferred Limited Partnership Units in respect of which a notice for reclassification into Series 1 Preferred Limited Partnership Units has been provided. The Partnership will give written notice thereof to all affected Holders of Series 1 Preferred Limited Partnership Units at least five (5) days prior to the applicable Series 1 Reclassification Date and will issue and deliver, or cause to be delivered, prior to such Series 1 Reclassification Date, at the expense of the Partnership, to such Holders of Series 1 Preferred Limited Partnership Units, who have surrendered for reclassification any endorsed certificate or certificates representing Series 1 Preferred Limited Partnership Units, new certificates representing the Series 1 Preferred Limited Partnership Units represented by any certificate or certificates surrendered as aforesaid.

5.2 Automatic Reclassification

If the Partnership determines that there would remain Outstanding on a Series 1 Reclassification Date less than 1,000,000 Series 1 Preferred Limited Partnership Units after taking into account all Series 1 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 2 Preferred Limited Partnership Units has been provided and all Series 2 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 1 Preferred

Limited Partnership Units has been provided, then, all, but not part, of the remaining Outstanding Series 1 Preferred Limited Partnership Units will automatically be reclassified into Series 2 Preferred Limited Partnership Units on the basis of one (1) Series 2 Preferred Limited Partnership Unit for each Series 1 Preferred Limited Partnership Unit on the applicable Series 1 Reclassification Date. The Partnership shall give notice in writing thereof to the Holders of such remaining Series 1 Preferred Limited Partnership Units at least five (5) days prior to the Series 1 Reclassification Date.

5.3 Manner of Reclassification

(a) The Reclassification Privilege may be exercised by notice in writing (an “Election Notice”) given not earlier than the 30th day prior to a Series 1 Reclassification Date but not later than 5:00 p.m. (Toronto time) on the 13th day preceding the applicable Series 1 Reclassification Date during usual business hours at any principal 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 1 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 1 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 1 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.

(b) If the Partnership does not receive an Election Notice from a Holder of Series 1 Preferred Limited Partnership Units during the notice period therefor, then the

Series 1 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) In the event the Partnership is required to reclassify all remaining Outstanding Series 1 Preferred Limited Partnership Units into Series 2 Preferred Limited Partnership Units on the applicable Series 1 Reclassification Date as provided for in Section 5.2, the Series 1 Preferred Limited Partnership Units in respect of which the Holders have not previously elected to reclassify will be reclassified on the Series 1 Reclassification Date into Series 2 Preferred Limited Partnership Units and the Holders thereof will be deemed to be Holders of Series 2 Preferred Limited Partnership Units at 5:00 p.m. (Toronto time) on the Series 1 Reclassification Date and will be entitled, upon surrender during usual business hours at any principal 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 1 Preferred Limited Partnership Units not previously provided for reclassification, to receive a certificate or certificates representing the same number of Series 2 Preferred Limited Partnership Units in the manner and subject to the terms and provisions as provided in this Section 5.3.

(d) As promptly as practicable after the Series 1 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 1 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 2 Preferred Limited Partnership Units and the number of remaining Series 1 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 1 Reclassification Date, so that the rights of the Holder of such Series 1 Preferred Limited Partnership Units as the Holder thereof will cease at such time and the person or persons entitled to receive the Series 2 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 2 Preferred Limited Partnership Units at such time.

(e) The Holder of any Series 1 Preferred Limited Partnership Unit on the record date for any Series 1 Distributions declared payable on such unit will be entitled to such distributions notwithstanding that such unit is reclassified into a Series 2 Preferred Limited Partnership Unit after such record date and on or before the date of the payment of such distribution.

(f) The issuance of certificates for the Series 2 Preferred Limited Partnership Units upon the reclassification of Series 1 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 2 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 2 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 2 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.

5.4 Status of Reclassified Series 1 Preferred Limited Partnership Units

The reclassification of Series 1 Preferred Limited Partnership Units into Series 2 Preferred Limited Partnership Units shall not give rise to a redemption or cancellation of such Preferred Units.

5.5 Right Not to Deliver Series 1 Preferred Limited Partnership Units

On the exercise of the Reclassification Privilege by a Holder, the Partnership reserves the right not to reclassify the Series 1 Preferred Limited Partnership Units held by any Ineligible Person.

6. Restrictions on Distributions and Retirement and Issue of Units

(a) declare, pay or set apart for payment any distributions (other than distributions payable in Junior Securities) in respect of any Junior Securities;

(b) except out of the net cash proceeds of a substantially concurrent issue of Junior Securities, redeem or call for redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any Junior Securities;

(c) redeem or call for redemption, purchase, or otherwise pay off or retire for value or make any return of capital in respect of less than all of the Series 1 Preferred Limited Partnership Units then Outstanding; or

(d) except pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provisions attaching thereto, redeem or call for redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any Parity Securities;

unless, in each such case, all accrued and unpaid Series 1 Distributions up to and including the Series 1 Distribution payable for the last completed Distribution Period, and all accrued and unpaid distributions up to and including the distribution payable for the last completed period for which distributions were payable on all Parity Securities and Senior Securities, have been declared and paid or set apart for payment.

7. Purchase for Cancellation

Subject to applicable law and to the provisions described in Section 6, the Partnership may at any time purchase for cancellation the whole or any part of the Series 1 Preferred Limited Partnership Units Outstanding from time to time, in the open market through or from an investment dealer or any firm holding membership on a recognized stock exchange, or by private agreement or otherwise, at the lowest price or prices at which, in the opinion of the Managing General Partner, such units are obtainable.

8. Voting Rights

The Holders shall not have any right or authority to act for or bind the Partnership or to take part or in any way to interfere in the conduct or management of the Partnership or (except as otherwise provided by law and except for meetings of the holders of Class A Preferred Limited Partnership Units as a class and meetings of the Holders as a series) be entitled to receive notice of, attend, or vote at any meeting of unitholders of the Partnership.

9. Modifications

The provisions attaching to the Series 1 Preferred Limited Partnership Units as a series may be repealed, altered, modified or amended from time to time with such approval as may then be required by applicable law, subject to a minimum requirement that such approval be passed by of the requisite affirmative vote of the votes cast at a meeting of the Holders of the Series 1 Preferred Limited Partnership Units duly called and held for that purpose, or given by resolution signed by the requisite percentage of Holders of Series 1 Preferred Limited Partnership Units, in each case, in accordance with Section 10, hereof.

10. Approval of Holders of Series 1 Preferred Limited Partnership Units

10.1 Approval

At such adjourned meeting, the Holders of Series 1 Preferred Limited Partnership Units represented in person or by proxy may transact the business for which the meeting was originally called and the Holders of Series 1 Preferred Limited Partnership Units then represented in person or by proxy shall form the necessary quorum.

11. Tax Matters

The Series 1 Distribution, whether paid or accrued, shall be treated as a guaranteed payment within the meaning of Section 707(c) of the Code, including for the purpose of determining Net Income and Net Loss and otherwise maintaining Capital Accounts, unless there is a change in Tax law or administrative practice that requires treatment other than as a guaranteed payment for U.S. federal income tax purposes, as determined in the sole discretion of the Managing General Partner. For U.S. federal income tax purposes, the deduction attributable to any amount treated as a guaranteed payment under this Section 11 shall be specially allocated to the Partners in a manner determined by the Managing General Partner in its sole discretion that is not inconsistent with the applicable provisions of the Code and Treasury Regulations.

Accidental failure to give Notice, including invitation for tenders or other communication to one or more Holders shall not affect the validity of the Notices properly given or any action taken pursuant to such Notice but, upon such failure being discovered, such Notice shall be given forthwith to such Holder or Holders.

Attaching to the Cumulative Class A Preferred Limited Partnership Units, Series 2

1. Consideration for Issue

The consideration for the issue of each Series 2 Preferred Limited Partnership Unit shall be C$25.00 or its equivalent in property or past services.

2. Distributions

2.1 Cumulative Preferential Distributions

The holders of the then Outstanding Series 2 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 properly applicable to the payment of distributions and without regard to the income of the Partnership, cumulative preferential cash distributions (the “Series 2 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 each Quarterly Floating Rate Period, Series 2 Distributions payable on the Series 2 Preferred Limited Partnership Units will be in an amount per Series 2 Preferred Limited Partnership Unit determined by multiplying the Floating Quarterly Distribution Rate applicable to such Quarterly Floating 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 Quarterly Floating Rate Period.

(b) In respect of each Quarterly Floating Rate Period, the Partnership will, during such Quarterly Floating Rate Period, calculate on each Floating Rate Calculation Date the Floating Quarterly Distribution Rate for such Quarterly Floating Rate Period and will, on the Floating Rate Calculation Date, give written notice thereof to the Holders. Each such determination by the Partnership of the Quarterly Floating Distribution Rate will, in the absence of manifest error, be final and binding upon the Partnership and upon all Holders of Series 2 Preferred Limited Partnership Units.

(c) If on any Distribution Payment Date, the Series 2 Distributions accrued to such date are not paid in full on all of the Series 2 Preferred Limited Partnership Units then Outstanding, such Series 2 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 properly applicable to the payment of such Series 2 Distributions.

(d) The Holders shall not be entitled to any distributions other than or in excess of the Series 2 Distributions.

(e) The Record Date for the payment of Series 2 Distributions will be the last Business Day of the calendar month prior to the calendar month during which a Distribution Payment Date falls, or such other record date if any, as may be fixed by the Managing General Partner.

Series 2 Distributions shall (except in case of redemption or reclassification in which case payment of Series 2 Distributions shall be made on surrender of the certificate representing the Series 2 Preferred Limited Partnership Units to be redeemed or reclassified) be paid by (i) posting in a postage paid envelope addressed to each Holder 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, a cheque for such Series 2 Distributions (less any tax required to be deducted and withheld) payable to the order of such Holder or, in the case of joint Holders, to the order of all such Holders failing written instructions from them to the contrary or (ii) by any other reasonable means the Partnership deems desirable. 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 2 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 Distributions to the extent of the sum represented thereby (plus the amount of any tax required to be deducted and withheld as aforesaid) 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 Quarterly Floating Rate Period

Subject to the Section 2.1, for any period that is less than a full Quarterly Floating Rate Period, with respect to any Series 2 Preferred Limited Partnership Unit (i) that is issued, redeemed, reclassified or purchased during such Quarterly Floating Rate Period or (ii) in respect of which assets of the Partnership are distributed to the Holders thereof pursuant to Section 3, the Holders shall be entitled to receive, and the Partnership shall pay thereon, if, as and when declared by the Managing General Partner, out of moneys of the Partnership properly applicable to the payment of distributions and without regard to the income of the Partnership, Series 2 Distributions as follows. In respect of any period that is less than a full Quarterly Floating Rate Period, a distribution in an amount per Series 2 Preferred Limited Partnership Unit equal to the amount obtained (rounded to four decimal places) when the product of the Floating Quarterly Distribution Rate and C$25.00 is multiplied by a fraction, the numerator of which is the number of calendar days elapsed in the relevant period and the denominator of which is the number of calendar days in the Quarterly Floating Rate Period in which such period falls.

3. Rights on Liquidation

In the event of the liquidation, dissolution or winding-up of the Partnership, whether voluntary or involuntary, or any other distribution of assets of the Partnership among its unitholders for the purpose of winding-up its affairs, unless the Partnership is continued under the election to reconstitute and continue the Partnership pursuant to Section 16.2 of the Agreement, the Holders shall be entitled to receive C$25.00 per Series 2 Preferred Limited Partnership Unit held by them, together with all accrued (whether or not declared) and unpaid Series 2 Distributions up to but excluding the date of payment or distribution (less any tax required to be deducted and withheld by the Partnership), before any amounts shall be paid or any assets of the Partnership distributed to the holders of any Junior Securities. Upon payment of such amounts, the Holders shall not be entitled to share in any further distribution of the assets of the Partnership.

4. Redemption at the Option of the Partnership

The Partnership may not redeem any of the Series 2 Preferred Limited Partnership Units prior to June 30, 2020. Thereafter, the Partnership may, subject to applicable law and to the provisions described under Section 6 below, upon giving notice as hereinafter provided, at its option, at any time, without the consent of the Holders redeem all, or from time to time any part, of the then Outstanding Series 2 Preferred Limited Partnership Units by the payment of an amount in cash for each Series 2 Preferred Limited Partnership Unit so redeemed equal to (i) in the case of redemptions on June 30, 2025 and on June 30 every five years thereafter (each a “Series 2 Reclassification Date”), C$25.00, or (ii) C$25.50 in the case of redemptions on any date which is not a Series 2 Reclassification Date on or after June 30, 2020, in each case including all accrued and unpaid Series 2 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 2 Preferred Limited Partnership Units are at any time to be redeemed, then the particular Series 2 Preferred Limited Partnership Units to be redeemed shall be selected on a pro rata basis disregarding fractions or, if the Series 2 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.

The Partnership shall give notice in writing not less than 25 days nor more than 60 days prior to the applicable Series 2 Reclassification Date or such other date on which the Series 2 Preferred Limited Partnership Units are to be redeemed of its intention to redeem such Series 2 Preferred Limited Partnership Units to each person who at the date of giving such notice is the Holder of Series 2 Preferred Limited Partnership Units to be redeemed. 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 2 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 2 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 2 Preferred Limited Partnership Units so called for redemption. Such payment 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 2 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 2 Preferred Limited Partnership Units called for redemption shall cease to be entitled to Series 2 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 2 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. 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 2 Preferred Limited Partnership Units

The Partnership will provide written notice not less than 25 and not more than 60 days prior to the applicable Series 2 Reclassification Date to the Holders of the reclassification privilege provided for herein (the “Reclassification Privilege”). Such notice shall (i) set out the Series 2 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.

(b) If the Partnership gives notice as provided in Section 4 to the Holders of the redemption of all the Series 2 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 2 Preferred Limited Partnership Units to reclassify such Series 2 Preferred Limited Partnership Units as herein provided will cease and terminate in that event.

(c) Holders of Series 2 Preferred Limited Partnership Units shall not be entitled to reclassify their units into Series 1 Preferred Limited Partnership Units on a Series 2 Reclassification Date if the Partnership determines that there would remain Outstanding on the Series 2 Reclassification Date less than 1,000,000 Series 1 Preferred Limited Partnership Units after taking into account all Series 2 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 1 Preferred Limited Partnership Units has been provided and all Series 1 Preferred Limited Partnership Units in respect of which a notice for reclassification into Series 2 Preferred Limited Partnership Units has been provided.

5.2 Automatic Reclassification

If the Partnership determines that there would remain Outstanding on a Series 2 Reclassification Date less than 1,000,000 Series 2 Preferred Limited Partnership Units after taking into account all Series 2 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 1 Preferred Limited Partnership Units has been provided and all Series 1 Preferred Limited Partnership Units in respect of which a notice of reclassification into Series 2 Preferred Limited Partnership Units has been provided, then, all, but not part, of the remaining Outstanding Series 2 Preferred Limited Partnership Units will automatically be reclassified into Series 1 Preferred Limited Partnership Units on the basis of one (1) Series 1 Preferred Limited Partnership Unit for each Series 2 Preferred Limited Partnership Unit on the applicable Series 2 Reclassification Date. The Partnership shall give notice in writing thereof to the Holders of such remaining Series 2 Preferred Limited Partnership Units at least five (5) days prior to the Series 2 Reclassification Date.

5.3 Manner of Reclassification

(a) The Reclassification Privilege may be exercised by notice in writing (an “Election Notice”) given not earlier than the 30th day prior to a Series 2 Reclassification Date but not later than 5:00 p.m. (Toronto time) on the 13th day preceding the applicable Series 2 Reclassification Date during usual business hours at any principal 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 2 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 2 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 2 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.

(b) If the Partnership does not receive an Election Notice from a Holder of Series 2 Preferred Limited Partnership Units during the notice period therefor, then the Series 2 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) In the event the Partnership is required to reclassify all remaining Outstanding Series 2 Preferred Limited Partnership Units into Series 1 Preferred Limited Partnership Units on the applicable Series 2 Reclassification Date as provided for in Section 5.2, the Series 2 Preferred Limited Partnership Units in respect of which the Holders have not previously elected to reclassify will be reclassified on the Series 2 Reclassification Date into Series 1 Preferred Limited Partnership Units and the Holders thereof will be deemed to be Holders of Series 1 Preferred Limited Partnership Units at 5:00 p.m. (Toronto time) on the Series 2 Reclassification Date and will be entitled, upon surrender during usual business hours at any principal 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 2 Preferred Limited Partnership Units not previously provided for reclassification, to receive a certificate or certificates representing the same

number of Series 1 Preferred Limited Partnership Units in the manner and subject to the terms and provisions as provided in this Section 5.3.

(d) As promptly as practicable after the Series 2 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 2 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 1 Preferred Limited Partnership Units and the number of remaining Series 2 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 2 Reclassification Date, so that the rights of the Holder of such Series 2 Preferred Limited Partnership Units as the Holder thereof will cease at such time and the person or persons entitled to receive the Series 1 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 1 Preferred Limited Partnership Units at such time.

(e) The Holder of any Series 2 Preferred Limited Partnership Unit on the record date for any Series 2 Distributions declared payable on such unit will be entitled to such distributions notwithstanding that such unit is reclassified into a Series 1 Preferred Limited Partnership Unit after such record date and on or before the date of the payment of such distribution.

(f) The issuance of certificates for the Series 1 Preferred Limited Partnership Units upon the reclassification of Series 2 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 1 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 1

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 1 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.

5.4 Status of Reclassified Series 2 Preferred Limited Partnership Units

The reclassification of Series 2 Preferred Limited Partnership Units into Series 1 Preferred Limited Partnership Units shall not give rise to a redemption or cancellation of such Preferred Units.

(c) redeem or call for redemption, purchase, or otherwise pay off or retire for value or make any return of capital in respect of less than all of the Series 2 Preferred Limited Partnership Units then Outstanding; or

unless, in each such case, all accrued and unpaid Series 2 Distributions up to and including the Series 2 Distribution payable for the last completed Quarterly Floating Rate Period, and all accrued and unpaid distributions up to and including the distribution payable for the last completed period for which distributions were payable on all Parity Securities and Senior Securities, have been declared and paid or set apart for payment.

(a) “accrued and unpaid distributions” means the aggregate of (i) all unpaid Series 2 Distributions for any completed Quarterly Floating Rate Period; and (ii) a cash amount calculated as though Series 2 Distributions had been accruing on a day to day basis from but excluding the date on which the last quarterly distribution was payable up to and including the date to which the computation of accrued distributions is to be made; provided in the case of each of (i) and (ii), no amount shall be included in the accrued and unpaid Series 2 Distributions that would result in the duplication in payment by the Partnership of the amount of any distribution on the Series 2 Preferred Limited Partnership Units;

(b) in the event that any date on which any Series 2 Distribution is payable by the Partnership, or any date on or by which any other action is required to be taken by

the Partnership or the Holders hereunder, is not a Business Day, then such distribution shall be payable, or such other action shall be required to be taken, on or by the next succeeding day that is a Business Day;

(c) in the event of the non-receipt of a cheque by a Holder of Series 2 Preferred Limited Partnership Units entitled to the cheque, or the loss or destruction of the cheque, the Partnership, on being furnished with reasonable evidence of non-receipt, loss or destruction, and an indemnity reasonably satisfactory to the Partnership, will issue to the Holder a replacement cheque for the amount of the original cheque; and

(d) the Partnership will be entitled to deduct or withhold from any amount payable to a Holder of Series 2 Preferred Limited Partnership Units under these Series 2 Preferred Limited Partnership Units Provisions any amount required by law to be deducted and withheld from that payment.
