(b) The Debentures shall be dated June 15, 2004, and shall bear interest from such date at the rate of 8.0% per annum, payable in semi-annual payments on February 28 and August 31 in each year, the first such payment to fall due, subject as hereinafter provided, on February 28, 2005 and the last such payment (representing interest payable from the last Interest Payment Date to, but excluding, the Maturity Date of the Initial Debentures), subject as hereinafter provided, to fall due on August 31, 2009, payable after as well as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded semi-annually.

The Debentures will mature on August 31, 2009, provided that if the closing of the Chevron Acquisition does not take place by 5:00 p.m.

(c) The Debentures will be redeemable in accordance with the terms of Article 4, provided that the Debentures will not be redeemable on or before August 31, 2007, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein.

(i) Upon and subject to the terms and conditions of Article 10, the Trust may elect, from time to time, to satisfy its Interest Obligation on the Debentures on any Interest Payment Date (or on redemption or maturity) by delivering Trust Units to the Debenture Trustee.

(j) Within 30 days following the occurrence of a Change of Control, and subject to the provisions and conditions of Section 2.4(i), the Trust shall be obligated to offer to purchase the Debentures. The terms and conditions of such obligation are set forth below:

(i) Within 30 days following the occurrence of a Change of Control, the Trust shall deliver to the Debenture Trustee, and the Debenture Trustee shall promptly deliver to the holders of the Debentures, a notice stating that there has been a Change of Control and specifying the circumstances surrounding such event (a "Change of Control Notice") together with an offer in writing (the "Offer") to purchase all then outstanding Debentures made in accordance with the requirements of Applicable Securities Legislation at a price equal to 101% of the principal amount thereof (the "Offer Price") plus accrued and unpaid interest on such Debentures up to, but excluding, the date of acquisition by the Trust or a related party of such Debentures (collectively, the "Total Offer Price").

5

(ii) If 90% or more in aggregate principal amount of Debentures outstanding on the date the Trust provides the Change of Control Notice and the Offer to holders of the Debentures have been tendered for purchase pursuant to the Offer on the expiration thereof, the Trust has the right and obligation upon written notice provided to the Debenture Trustee within 10 days following the expiration of the Offer, to redeem and shall redeem all the Debentures remaining outstanding on the expiration of the Offer at the Total Offer Price (the "90% Redemption Right").

(iii) Upon receipt of notice that the Trust has exercised or is exercising the 90% Redemption Right and is acquiring the remaining Debentures, the Debenture Trustee shall promptly provide written notice to each Debentureholder that did not previously accept the Offer that:

(A) the Trust has exercised the 90% Redemption Right and is purchasing all outstanding Debentures effective on the expiry of the Offer at the Total Offer Price, and shall include a calculation of the amount payable to such holder as payment of the Total Offer Price;

(B) each such holder must transfer their Debentures to the Debenture Trustee on the same terms as those holders that accepted the Offer and must send their respective Debentures, duly endorsed for transfer, to the Debenture Trustee within 10 days after the sending of such notice; and

(C) the rights of such holder under the terms of the Debentures and the Indenture cease effective as of the date of expiry of the Offer provided the Trust has, on or before the time of notifying the Debenture Trustee of the exercise of the 90% Redemption Right, paid the Total Offer Price to, or to the order of, the Debenture Trustee and thereafter the Debentures shall not be considered to be outstanding and the holder shall not have any right except to receive such holder's Total Offer Price upon surrender and delivery of such holder's Debentures in accordance with the Indenture.

(iv) The Trust shall, on or before 11:00 a.m. (Calgary Time), on the Business Day immediately prior to the expiry of the Offer, deposit with the Debenture Trustee or any paying agent to the order of the Debenture Trustee, such sums of money as may be sufficient to pay the Total Offer Price of the Debentures to be purchased or redeemed by the Trust on the expiry of the Offer, provided the Trust may elect to satisfy this requirement by providing the Debenture Trustee with a cheque for such amounts required under Section 2.4(i)(iv) post-dated to the date of expiry of the Offer. The Trust shall also deposit with the Debenture Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Debenture Trustee in connection with such purchase and/or redemption, as the case may be. Every such deposit shall be irrevocable. From the sums so deposited, the Debenture Trustee shall pay or cause to be paid to the holders of such Debentures, the Offer Price, and all accrued and unpaid interest, if any, to which they are entitled on the Trust's purchase or redemption.

(v) In the event that one or more of such Debentures being purchased in accordance with Section 2.4(i) becomes subject to purchase in part only, upon surrender of such Debentures for payment of the Total Offer Price, the Trust shall execute and the Debenture Trustee shall certify and deliver without charge to the holder thereof or upon

6

the holder's order, one or more new Debentures for the portion of the principal amount of the Debentures not purchased.

(vi) Debentures for which holders have accepted the Offer and Debentures which the Trust has elected to redeem in accordance with Section 2.4(i) shall become due and payable at the Total Offer Price on the date of expiry of the Offer, in the same manner and with the same effect as if it were the date of maturity specified in such Debentures, anything therein or herein to the contrary notwithstanding, and from and after such date of expiry of the Offer, if the money necessary to purchase or redeem the Debentures shall have been deposited as provided in Section 2.4(i) and affidavits or other proofs satisfactory to the Debenture Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest on the Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Debenture Trustee whose decision shall be final and binding upon all parties in interest.

(vii) In case the holder of any Debenture to be purchased or redeemed in accordance with Section 2.4(i) shall fail on or before the date of expiry of the Offer so to surrender such holder's Debenture or shall not within such time accept payment of the moneys payable, or give such receipt therefor, if any, as the Debenture Trustee may require, such moneys may be set aside in trust, either in the deposit department of the Debenture Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and the Debentureholder shall have no other right except to receive payment of the moneys so paid and deposited, upon surrender and delivery up of such holder's Debenture. In the event that any money required to be deposited hereunder with the Debenture Trustee or any depository or paying agent on account of principal, premium, if any, or interest, if any, on Debentures issued hereunder shall remain so deposited for a period of six years from the date of expiry of the Offer, then such moneys, together with any accumulated interest thereon, shall at the end of such period be paid over or delivered over by the Debenture Trustee or such depository or paying agent to the Trust and the Debenture Trustee shall not be responsible to Debentureholders for any amounts owing to them. Notwithstanding the foregoing, the Debenture Trustee will pay any remaining funds deposited hereunder prior to the expiry of six years after the date of expiry of the Offer to the Trust upon receipt from the Trust, or one of its Subsidiaries, of an unconditional letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Trust prior to the expiry of six years after the date of expiry of the Offer, the Trust shall reimburse the Debenture Trustee for any amounts required to be paid by the Debenture Trustee to a holder of a Debenture pursuant to the Offer after the date of such payment of the remaining funds to the Trust but prior to six years after the date of expiry of the Offer.

(viii) Subject to the provisions above related to Debentures purchased in part, all Debentures redeemed and paid under Section 2.4(i) shall forthwith be delivered to the Debenture Trustee and cancelled and no Debentures shall be issued in substitution therefor.

(k) The Debenture Trustee shall be provided with the documents and instruments referred to in Sections 2.5(b), (c) and (d) with respect to the Debentures prior to the issuance of the Debentures.

Underwriters or announced to the public that it does not intend to proceed with the Chevron Acquisition, the Debentures will mature on August 31, 2004.  If the Chevron Acquisition takes place prior to 5:00 p.m. (Calgary time) on August 31, 2004, the Maturity Date of the Debentures will be automatically extended from August 31, 2004 to August 31, 2009 without any further act or formality on the part of the Trust or the Debenture Trustee.

Interest hereon shall be payable by cheque mailed by prepaid ordinary mail or by electronic transfer of funds to the registered holder hereof and, subject to the provisions of the Indenture, the mailing of such cheque or the electronic transfer of such funds shall, to the extent of the sum represented thereby (plus the amount of any tax withheld), satisfy and discharge all liability for interest on this Debenture.

This Debenture is one of the 8.0% Convertible Unsecured Subordinated Debentures, due on the Maturity Date (referred to herein as the "Debenture") of the Trust issued or issuable under the provisions of the Indenture.  The Debentures authorized for issue are limited to an aggregate principal amount of $75,000,000 in lawful money of Canada.  Reference is hereby expressly made to the Supplemental Indenture for a description of the terms and conditions upon which the Debentures are or are to be issued and held and the rights and remedies of the holders of the Debentures and of the Trust and of the Debenture Trustee, all to the same effect as if the provisions of the Supplemental Indenture were herein set forth to all of which provisions the holder of this Debenture by acceptance hereof assents.

The Debentures are issuable only in denominations of $1,000 and integral multiples thereof. Upon compliance with the provisions of the Supplemental Indenture, Debentures of any denomination may be exchanged for an equal aggregate principal amount of Debentures in any other authorized denomination or denominations.

The whole, or if this Debenture is in a denomination in excess of $1,000, any part which is $1,000 or an integral multiple thereof, of the principal of this Debenture is convertible, at the option of the holder hereof, upon surrender of this Debenture at the principal office of the Debenture Trustee in Calgary, Alberta or Toronto, Ontario, at any time prior to the close of business on the earlier of August 31, 2004 or August 31, 2009, as applicable, and the last Business Day immediately preceding the date specified by the Trust for redemption of the Debentures, into Trust Units (without adjustment for interest accrued hereon or for dividends or distributions on Trust Units issuable upon conversion) at a conversion price of $13.50 (the "Conversion Price") per Trust Unit, being a rate of approximately 74.071 Trust Units for each $1,000 principal amount of Debentures, all subject to the terms and conditions and in the manner set forth in the Supplemental Indenture.  The Supplemental Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Trust Units will be issued on any conversion but in lieu thereof, the Trust will satisfy such fractional interest by a cash payment equal to the market price of such fractional interest determined in accordance with the Supplemental Indenture.  No adjustment in the number of Trust Units to be issued upon conversion will be made for distributions or dividends on Trust Units issuable upon conversion or for interest accrued on Debentures surrendered for conversion.

This Debenture will be redeemed at the option of the Trust on the terms and conditions set out in the Supplemental Indenture at the redemption price therein and herein set out provided that this Debenture is not redeemable on or before August 31, 2007, except in the event of the satisfaction of certain conditions after a Change of Control has occurred.  After August 31, 2007 and on or prior to August 31, 2008, the Debentures may be redeemed at the option of the Trust in whole or in part from time to time on notice as provided for in the Indenture at a price equal to $1,050 per $1,000 principal amount of Debenture plus accrued and unpaid interest.  After August 31, 2008, the Debentures will be redeemable prior to maturity in whole or in part from time to time at the option of the Trust on notice as provided for

in the Indenture at a price equal to $1,025 per $1,000 principal amount of Debenture plus accrued and unpaid interest. The Trust may, on notice as provided in the Supplemental Indenture, at its option and subject to any applicable regulatory approval, elect to satisfy its obligation to pay all or any portion of the applicable Redemption Price by the issue of that number of Trust Units obtained by dividing the applicable Redemption Price by 95% of the weighted average trading price of the Trust Units on the Toronto Stock Exchange for the 20 consecutive trading days ending on the fifth trading day preceding the Redemption Date.

Upon the occurrence of a Change of Control of the Trust, the Trust is required to make an offer to purchase all of the Debentures at a price equal to 101% of the principal amount of such Debentures plus accrued and unpaid interest up to, but excluding, the date the Debentures are so repurchased (the "Offer").  If 90% or more of the principal amount of all Debentures outstanding on the date the Trust provides notice of a Change of Control to the Debenture Trustee have been tendered for purchase pursuant to the Offer, the Trust has the right to redeem and shall redeem all the remaining outstanding Debentures on the same date and at the same price.

If a takeover bid for Debentures, within the meaning of the Securities Act (Alberta), is made and 90% or more of the principal amount of all the Debentures (other than Debentures held at the date of the takeover bid by or on behalf of the Offeror, Associates or Affiliates of the Offeror or anyone acting jointly or in concert with the Offeror) are taken up and paid for by the Offeror, the Offeror will be entitled to acquire the Debentures of those holders who did not accept the offer on the same terms as the Offeror acquired the first 90% of the principal amount of the Debentures.

The Trust may, on notice as provided in the Supplemental Indenture, at its option and subject to any applicable regulatory approval, elect to satisfy the obligation to repay all or any portion of the principal amount of this Debenture due on the Maturity Date by the issue of that number of Freely Tradeable Trust Units obtained by dividing the principal amount of this Debenture to be paid for in Trust Units pursuant to the exercise by the Trust of the Unit Repayment Right by 95% of the weighted average trading price of the Trust Units on the Toronto Stock Exchange for the 20 consecutive trading days ending on the fifth trading day preceding the Maturity Date.

The indebtedness evidenced by this Debenture, and by all other Debentures now or hereafter certified and delivered under the Indenture, is a direct unsecured obligation of the Trust, and is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment of all Senior Indebtedness, whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed, provided that the Debentures will rank pari passu with the Debentures.

The principal hereof may become or be declared due and payable before the stated maturity in the events, in the manner, with the effect and at the times provided in the Indenture.

The Indenture contains provisions making binding upon all holders of Debentures outstanding thereunder (or in certain circumstances specific series of Debentures) resolutions passed at meetings of such holders held in accordance with such provisions and instruments signed by the holders of a specified majority of Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Debenture or the Indenture.

The Indenture contains provisions disclaiming any personal liability on the part of holders of Trust Units, or the trustees, officers or agents of the Trust in respect of any obligation or claim arising out of the Indenture or this Debenture.
