3. Amendments to Article 4

(a) Section 4.1.2 is hereby deleted in its entirety and replaced with the following:

The Income for Canadian Tax Purposes for a given fiscal year of the Partnership will be allocated to each Partner in an amount calculated by multiplying the 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 and the denominator of which is the aggregate amount of the distributions made by the Partnership to Partners 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 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 been 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 so allocated to a Partner 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. 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 for Canadian Tax Purposes or the Loss for Canadian Tax Purposes, as the case may be, 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 held by them on each such date, such amount of the Income for Canadian Tax Purposes or the Loss for Canadian Tax Purposes, as the case may be, as the General Partner determines is reasonable in the circumstances having regard to such factors as the General Partner considers to be relevant, including, without limitation, the relative amount of capital contributed to the Partnership on the issuance of 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 of the Loss for Canadian Tax Purposes, as the case may be, pro rata to their respective Percentage Interests on 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 Units 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 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. In furtherance of the foregoing, the General Partner may adjust allocations of items that would otherwise be made pursuant to the terms of this Agreement to the extent necessary to avoid an adverse effect on the Limited Partners, subject to the approval of an Independent Committee.

(b) Section 4.3 is hereby deleted in its entirety and replaced with the following:

The General Partner may in its sole discretion make distributions at any time or from time to time to the Preferred Unitholders in accordance with this Agreement. Subject to the terms of any Preferred Units then Outstanding, the General Partner may in its sole discretion make distributions at any time or from time to time to the Partners in accordance with their Percentage Interests, provided that all such distributions to the Limited Partners shall be paid by the Partnership directly or through the Transfer Agent or through any other Person or agent only to the Record

Holders pro rata according to their respective Percentage Interests as of the Record Date set for such distribution. The payment of any distributions in accordance with this Agreement shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise. The amount of Taxes withheld or paid by the Partnership or another member of the BIP Group in respect of a Partnership Interest held by a Partner shall be treated either as a distribution to such Partner or as a general expense of the Partnership, as determined by the General Partner in its sole discretion, and the General Partner shall report to the Partners on an annual basis the amount of such Taxes withheld or paid.

4. Amendments to Article 5

Section 5.2 is hereby deleted in its entirety and replaced with the following:

Except as provided in Article 13 and Article 15, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the Assets, taken as a whole, in a single transaction or a series of related transactions without the prior approval of the holders of a majority of the voting power of Outstanding Equity Units; provided however that this provision shall not preclude or limit the General Partner’s ability, in its sole discretion, to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the Assets (including for the benefit of Persons other than members of the BIP Group, including Affiliates of the General Partner) and shall not apply to any forced sale of any or all of the Assets pursuant to the foreclosure of, or other realization upon, any such encumbrance. The General Partner shall not, on behalf of the Partnership, except as permitted under Section 10.6 and Section 12.1, elect or cause the Partnership to elect a successor general partner of the Partnership.

5. Amendments to Article 12

(a) Section 12.1.4 is hereby deleted in its entirety and replaced with the following:

If the General Partner gives a notice of withdrawal pursuant to Sections 12.1.1.1 or 12.1.2, holders of at least a majority of the voting power of the Outstanding Equity Units may, prior to the effective date of such withdrawal, elect a successor General Partner. If, prior to the effective date of the General Partner’s withdrawal, a successor is not selected by the holders of Equity Units as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 13.2. Any such successor General Partner shall be subject to the provisions of Section 11.2.

(b) Section 12.2.2 is hereby deleted in its entirety and replaced with the following:

For purposes of this Section 12.2.2, the fair market value of the Departing General Partner Unit shall be determined by agreement between the Departing General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s departure, by an independent investment banking firm or other independent expert selected by the Departing General Partner and its successor, which, in turn, may rely on other experts and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such departure, then the Departing General Partner shall designate an independent investment banking firm or other independent expert, the Departing General Partner’s successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which shall determine the fair market value of the General Partner Unit. In making its determination, such independent investment banking firm or other independent expert shall consider the then current trading price of Equity Units on any Securities Exchange on which Equity Units are then listed, the value of the Assets, the rights and obligations of the General Partner and other factors it may deem relevant.

If the General Partner Unit is not acquired in the manner set forth in Section 12.2.1, the Departing General Partner shall become a Limited Partner and the General Partner Unit shall be converted into an Equity Unit pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 12.2.1, without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor).

6. Amendments to Article 13

(a) Section 13.3.3 is hereby deleted in its entirety and replaced with the following:

all property and all cash in excess of that required to discharge liabilities of the Partnership pursuant to Section 13.3.2 shall be distributed to the Preferred Unitholders in priority to the other Partners, up to the amount of the liquidation entitlement of the Preferred Units as set out in Schedule A, and any remaining amount available for distribution will be distributed to the Partners in accordance with their Percentage Interests, in each case as

of the date chosen by the Liquidator. In the event that the property and cash to be distributed to the Preferred Unitholders on the liquidiation of the Partnership is not sufficient to pay the full amount of the liquidation entitlement of the Preferred Units as set out in Schedule Afor each Preferred Unit then Outstanding, the amount available for distribution shall be paid to the Preferred Unitholders pro rata in proportion to their respective relative percentage of Preferred Units held (determined by reference to the aggregate value of the issue price of the Preferred Units held by each Preferred Unitholder relative to the aggregate value of the issue price of all Preferred Units then Outstanding). Such distributions shall be made by the end of the taxable year in which the liquidation of the Partnership occurs (or, if later, within 90 days after the date of such liquidation).

7. Amendments to Article 14

(a) Section 14.1.6 is hereby deleted in its entirety and replaced with the following:

(b) Section 14.2.2 is hereby deleted in its entirety and replaced with the following:

subject to the terms of any Preferred Units then Outstanding, a proposed amendment shall be effective upon its approval by the General Partner and, where required under this Agreement or by the Limited Partnership Act, on the consent, vote or approval of the amendment by the holders of a majority of the voting power of the Outstanding Equity Units.

Except as otherwise provided, and without limitation of the General Partner’s authority to adopt amendments to this Agreement as contemplated in Section 14.1, the General Partner may amend the Partnership Agreement without the approval of holders of Outstanding Equity Units, except that any amendment that would have a material adverse effect on the rights or preferences of any class of Outstanding Partnership Interests in relation to other classes of Partnership Interests must be consented to or approved by the holders of at least a majority of the Outstanding Partnership Interests of the class affected.

(d) Section 14.3.4 is hereby deleted in its entirety and replaced with the following:

Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 14.1, no amendments shall become effective without the approval of at least 90% of the voting power of the Outstanding Equity Units unless the Partnership obtains an Opinion of Counsel to the effect that (a) such amendment will not cause the Partnership to be treated as an association taxable as a corporation or otherwise taxable as an entity for tax purposes (provided that for U.S. tax purposes the General Partner has not made the election contemplated by Section 9.6) and (b) such amendment will not affect the limited liability of any Limited Partner or any limited partner of the Infrastructure Partnership under applicable law.

(e) Section 14.3.5 is hereby deleted in its entirety and replaced with the following:

At any meeting of the Limited Partners, or any class or series thereof, duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent a majority of the Outstanding Units entitled to vote and be present in person or by proxy at such meeting shall be deemed to constitute the act of all Limited Partners or any class or series thereof, unless a greater or different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Units that in the aggregate represent at least such greater or different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of the voting power of Outstanding Units specified in this Agreement (including Outstanding Units deemed owned by the General Partner).

The General Partner may specify that any written ballot from Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partner, the Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted.

(h) Section 14.11.1 is hereby deleted in its entirety and replaced with the following:

Only those holders of Units of the class or series for which a meeting has been called who are Record Holders on the Record Date set pursuant to Section 14.6 (and also subject to the limitations contained in the definition of “Outstanding”) shall be entitled to notice of, and to vote at, a meeting of Partners or to act with respect to matters as to which the holders of the Outstanding Units have the right to vote or to act.

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 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 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 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 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 General Partner.

Series 1 Distributions shall (except in case of redemption or reclassification in which case payment of Series 1 Distributions shall, subject to the provisions of Section 17, 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.

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 13.2.2 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 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, subject to the provisions of Section 17. 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, 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.

The Partnership will give written notice thereof to all affected Holders of Series 1 Preferred Limited Partnership Units at least seven (7) days prior to the applicable Series 1 Reclassification Date and, subject to the provisions of Section 17, 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 seven (7) days prior to the Series 1 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 earlier than the 30th day prior to a Series 1 Reclassification Date but not later than 5:00 p.m. (Toronto time) on the 15th day preceding the applicable Series 1 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 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) Subject to the provisions of Section 17, 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 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 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) Subject to the provisions of Section 17, 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) Subject to the provisions of Section 17, 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.

In the event of such non payment, and for only so long as any such dividends remain in arrears, the Holders will be entitled to receive notice of and to attend each meeting of unitholders of the Partnership (other than any meetings at which only holders of another specified class or series are entitled to vote) and such Holders shall have the right, at any such meeting, to one vote for each Series 1 Preferred Limited Partnership Unit held. No other voting rights shall attach to the Series 1 Preferred Limited Partnership Units in any circumstances.

Series 1 Preferred Limited Partnership Units not issued or that have been issued and redeemed, reclassified or otherwise purchased or acquired by the Partnership shall be restored to the status of authorized but unissued Class A Preferred Limited Partnership Units without designation as to series, until such units are once more designated as part of a particular series by the General Partner.

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.

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 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 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 General Partner.

Series 2 Distributions shall (except in case of redemption or reclassification in which case payment of Series 2 Distributions shall, subject to the provisions of Section 17, 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 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 13.2.2 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 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, subject to the provisions of Section 17. 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, 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 2 Preferred Limited Partnership Units

5.1 Reclassification into Series 1 Preferred Limited Partnership Units at the Option of the Holder

(a) Holders of Series 2 Preferred Limited Partnership Units will have the right, at their option, on each Series 2 Reclassification Date, to reclassify, subject to the applicable law and the terms and provisions hereof, all or any part of the then Outstanding Series 2 Preferred Limited Partnership Units registered in the name of the Holder 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. 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. On the 30th day prior to the first day of 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 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. The Partnership will give written notice thereof to all affected

Holders of Series 2 Preferred Limited Partnership Units at least seven (7) days prior to the applicable Series 2 Reclassification Date and, subject to the provisions of Section 17, will issue and deliver, or cause to be delivered, prior to such Series 2 Reclassification Date, at the expense of the Partnership, to such Holders of Series 2 Preferred Limited Partnership Units, who have surrendered for reclassification any endorsed certificate or certificates representing Series 2 Preferred Limited Partnership Units, new certificates representing the Series 2 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 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 seven (7) days prior to the Series 2 Reclassification Date.

5.3 Manner of Reclassification

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) Subject to the provisions of Section 17, 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 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 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) Subject to the provisions of Section 17, 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) Subject to the provisions of Section 17, 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.

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 2 Preferred Limited Partnership Units held by any Ineligible Person.

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

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 2 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 General Partner, such units are obtainable.

8. Voting Rights

such non payment, and for only so long as any such dividends remain in arrears, the Holders will be entitled to receive notice of and to attend each meeting of unitholders of the Partnership (other than any meetings at which only holders of another specified class or series are entitled to vote) and such Holders shall have the right, at any such meeting, to one vote for each Series 2 Preferred Limited Partnership Unit held. No other voting rights shall attach to the Series 2 Preferred Limited Partnership Units in any circumstances. Upon payment of the entire amount of all Series 2 Distributions in arrears, the voting rights of the Holders shall forthwith cease (unless and until the same default shall again arise under the provisions of this Section 8).

9. Modifications

The provisions attaching to the Series 2 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 2 Preferred Limited Partnership Units duly called and held for that purpose, or given by resolution signed by the requisite percentage of Holders of Series 2 Preferred Limited Partnership Units, in each case, in accordance with Section 10, hereof.

10. Approval of Holders of Series 2 Preferred Limited Partnership Units

10.1 Approval

Series 2 Preferred Limited Partnership Units are present or represented by proxy. If at any such meeting the Holders of at least 25% of the then Outstanding Series 2 Preferred Limited Partnership Units are not present or represented by proxy within one half hour after the time appointed for such meeting, then the meeting shall be adjourned to such date not less than 5 days thereafter and to such time and place as may be designated by the chairman of such meeting, and no notice need be given of such adjourned meeting. At such adjourned meeting, the Holders(s) of Series 2 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 2 Preferred Limited Partnership Units then represented in person or by proxy shall form the necessary quorum.

Each Series 2 Preferred Limited Partnership Unit shall entitle the Holder thereof to one vote for the purposes of any approval at a meeting of the Holders of the Series 2 Preferred Limited Partnership Units or by written consent.

10.2 Formalities, etc.

11. Tax Matters

The Series 2 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 income, gain, loss, and expense of the Partnership and 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 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 General Partner in its sole discretion that is not inconsistent with the applicable provisions of the Code and Treasury Regulations.

12. Unissued or Reacquired Units

Series 2 Preferred Limited Partnership Units not issued or that have been issued and redeemed, reclassified or otherwise purchased or acquired by the Partnership shall be restored to the status of authorized but unissued Class A Preferred Limited Partnership Units without designation as to series, until such units are once more designated as part of a particular series by the General Partner.

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.
