                              THE SECOND DEBENTURES

2.1      FORM AND TERMS OF SECOND DEBENTURES

(a)      The Second Debentures authorized for issue immediately are limited to
         an aggregate principal amount of $100,000,000 and shall be designated
         as "Series 2, 8.00% Convertible Unsecured Subordinated Debentures".

(b)      The Second Debentures shall be dated as of August 10, 2004, shall
         mature on September 30, 2009 (the "MATURITY DATE") and shall bear
         interest from the date of issue at the rate of 8.00% per annum, payable
         in arrears in equal (with the exception of the first interest payment
         which will include interest from August 10, 2004 as set forth below)
         semi-annual payments of $40.00 per $1,000 of principal amount of the
         Second Debentures on March 31 and September 30 in each year, the first
         such payment to fall due on March 31, 2005 and the last such payment
         (representing interest payable from the last Interest Payment Date to,
         but excluding, the Maturity Date of the Second Debentures) to fall due
         on September 30, 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 first interest payment
         will include interest accrued from and including August 10, 2004 to,
         but excluding March 31, 2005, which will be equal to $51.06849 per
         $1,000 principal amount of the Second Debentures.

(c)      If the Closing does not take place by the Termination Time, the
         Corporation shall provide immediate notice in writing to the Debenture
         Trustee and shall cause an immediate public announcement, in accordance
         with Applicable Securities Legislation, to be made. The Debenture
         Trustee, forthwith upon receipt of such notice, shall cause notice to
         be given in accordance with the Indenture to each holder of Second
         Debentures of the occurrence of the Termination Time and that the
         Debentureholder has a right of redemption as provided for by this
         Section 2.1. A holder of the Second Debentures shall be entitled to
         require the Trust to redeem (the "HOLDERS' EARLY REDEMPTION") any or
         all of the Second Debentures registered in the name of such holder at a
         redemption price (the "HOLDERS' EARLY REDEMPTION PRICE") of $1,000 per
         $1,000 principal amount of Second Debentures and, in addition thereto,
         at the time of such redemption, the Trust shall pay to the holder
         accrued and unpaid interest to, but excluding, the Holders' Early
         Redemption Date (as defined below). Holders wishing to exercise the
         Holders' Early Redemption must provide a notice of redemption (a
         "HOLDER EARLY REDEMPTION NOTICE") of the Second Debentures, in the form
         of SCHEDULE "D" to this Supplemental Indenture, to the Trust in
         accordance with Section 14.1 of the Indenture not less than 10 Business
         Days from (but excluding) the Termination Date (the "HOLDERS' EARLY
         REDEMPTION DATE"). The provisions of Sections 4.4, 4.5, 4.7 and 4.8 of
         the Indenture shall apply, MUTATIS MUTANDIS, to the Holders' Early
         Redemption, with those Second Debentures in respect of which a Holders'
         Early Redemption Notice has been provided to be treated as "Debentures
         called for redemption", the Holders' Early Redemption Date to be
         considered for those purposes the "REDEMPTION DATE" and the Holders'
         Early Redemption Price to be treated as the "REDEMPTION PRICE". The
         provisions of Section 4.6 of the Indenture shall not be applicable to
         the Holders' Early Redemption.

(d)      If the Closing does not take place by the Termination Time and provided
         that following the redemption referred to in this Section 2.1(d) (the
         "TRUST EARLY REDEMPTION") not more than $40,000,000 in principal amount
         of Second Debentures are outstanding, Second Debentures may


                                       4


         be redeemed for cash on a pro rata basis at the option of the Trust in
         whole or in part at a redemption price (the "TRUST'S EARLY REDEMPTION
         PRICE") of $1,000 per $1,000 principal amount of Second Debentures and,
         in addition thereto, at the time of such redemption, the Trust shall
         pay to the holder accrued and unpaid interest to (but excluding) the
         Trust's Early Redemption Date (as defined below). In order to exercise
         such right of Trust's Early Redemption, the Trust must provide a
         redemption notice (the "TRUST'S EARLY REDEMPTION NOTICE") for the
         Second Debentures so to be redeemed substantially in the form of
         SCHEDULE "B" hereof given by the Trust to the holders of such Second
         Debentures in accordance with Section 14.2 of the Indenture not less
         than 10 Business Days from (but excluding) the Holders' Early
         Redemption Date (the "TRUST'S EARLY REDEMPTION DATE"). The provisions
         of Sections 4.2, 4.3 (excluding the time limitations set out therein in
         respect of the delivery of the Trust's Early Redemption Notice), 4.4,
         4.5, 4.7 and 4.8 of the Indenture shall apply, MUTATIS MUTANDIS, to the
         Trust Early Redemption, with those Second Debentures in respect of
         which a Trust's Early Redemption Notice has been provided to be treated
         as "Debentures called for redemption", the Trust's Early Redemption
         Date to be considered for those purposes the "Redemption Date" and the
         Trust's Early Redemption Price to be treated as the "Redemption Price".
         The provisions of Section 4.6 of the Indenture shall not be applicable
         for the Holder's Early Redemption.

(e)      The Second Debentures will be redeemable in accordance with the terms
         of Article 4 of the Indenture, provided that, subject to the Holders'
         Early Redemption and the Trust Early Redemption, the Second Debentures
         will not be redeemable on or before September 30, 2007, except in the
         event of the satisfaction of certain conditions after a Change of
         Control has occurred as outlined herein. Subsequent to September 30,
         2007 and on or prior to September 30, 2008, the Second 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 Section 4.3 of the Indenture at a
         Redemption Price of $1,050 per $1,000 principal amount of Second
         Debentures and, in addition thereto, at the time of redemption, the
         Trust shall pay to the holder accrued and unpaid interest. After
         September 30, 2008 and prior to maturity, the Second 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 Section 4.3 of the Indenture at a
         Redemption Price of $1,025 per $1,000 principal amount of Debentures
         and, in addition thereto, at the time of redemption, the Trust shall
         pay to the holder accrued and unpaid interest. The Redemption Notice
         for the Second Debentures shall be in the form of SCHEDULE "B" hereof.
         In connection with the redemption of the Second Debentures, the Trust
         may, at its option and subject to the provisions of Section 4.6 and
         subject to regulatory approval, elect to satisfy its obligation to pay
         all or a portion of the aggregate Redemption Price of the Second
         Debentures to be redeemed by issuing and delivering to the holders of
         such Second Debentures, such number of Freely Tradeable Trust Units as
         is obtained by dividing the Redemption Price by 95% of the Current
         Market Price in effect on the Redemption Date. Interest accrued and
         unpaid on the Second Debentures on the Redemption Date will be paid to
         holders of Second Debentures, in cash, in the manner contemplated in
         Section 4.5 of the Indenture. If the Trust elects to exercise such
         option, it shall so specify and provide details in the Redemption
         Notice.

(f)      The Second Debentures will be subordinated to the Senior Indebtedness
         of the Trust in accordance with the provisions of Article 5 of the
         Indenture.

(g)      Upon and subject to the provisions and conditions of Article 6 of the
         Indenture, the holder of each Second Debenture shall have the right at
         such holder's option, at any time when the register of the Debenture
         Trustee is open, prior to the close of business on the earlier of
         September 30, 2009 and the last Business Day immediately preceding the
         date specified by the Trust for redemption of the Second Debentures by
         notice to the holders of Second Debentures in accordance with Sections
         2.4(c) and 4.3 of the Indenture (the earlier of which will be the "TIME
         OF EXPIRY" for the


                                       5


         purposes of Article 6 of the Indenture in respect of the Second
         Debentures), to convert any part, which is $1,000 or an integral
         multiple thereof, of the principal amount of such Second Debenture into
         Trust Units at the Conversion Price in effect on the Date of
         Conversion. The Conversion Price in effect on the date hereof for each
         Trust Unit to be issued upon the conversion of Second Debentures shall
         be equal to $16.25 such that approximately 61.538462 Trust Units shall
         be issued for each $1,000 principal amount of Second Debentures so
         converted. No adjustment in the number of Trust Units to be issued upon
         conversion will be made for distributions on Trust Units issuable upon
         conversion or for interest accrued on the Second Debentures which are
         surrendered for conversion; however, holders converting their Second
         Debentures will receive all interest which has accrued to but excluding
         the Date of Conversion which has not been paid. The Conversion Price
         applicable to and the Trust Units, securities or other property
         receivable on the conversion of the Second Debentures is subject to
         adjustment pursuant to the provisions of Section 6.5 of the Indenture.

         Notwithstanding any other provisions of the Indenture or this
         Supplemental Indenture, if a Second Debenture is surrendered for
         conversion on an Interest Payment Date or during the five preceding
         Business Days, the person or persons entitled to receive Trust Units in
         respect of the Second Debenture so surrendered for conversion shall not
         become the holder or holders of record of such Trust Units until the
         Business Day following such Interest Payment Date.

(h)      On maturity of the Second Debentures, the Trust may, at its option and
         subject to the provisions of Section 4.10 of the Indenture, Section 2.1
         of this Supplemental Indenture and subject to regulatory approval,
         elect to satisfy its obligation to pay all or a portion of the
         aggregate principal amount of the Second Debentures due on maturity by
         issuing and delivering to such holders of Second Debentures, Freely
         Tradeable Trust Units pursuant to the provisions of Section 4.10 of the
         Indenture. If the Trust elects to exercise such option, it shall
         deliver a maturity notice (the "MATURITY NOTICE") to the holders of the
         Second Debentures in the form of SCHEDULE "C" of this Supplemental
         Indenture and provide the necessary details.

(i)      The Second Debentures shall be issued as Fully Registered Debentures in
         denominations of $1,000 and integral multiples of $1,000. Each Second
         Debenture and the certificate of the Debenture Trustee endorsed thereon
         shall be issued in substantially the form set out in SCHEDULE "A" of
         this Supplemental Indenture, with such insertions, omissions,
         substitutions or other variations as shall be required or permitted by
         this Indenture, and may have imprinted or otherwise reproduced thereon
         such legend or legends or endorsements, not inconsistent with the
         provisions of the Indenture or this Supplemental Indenture, as may be
         required to comply with any law or with any rules or regulations
         pursuant thereto or with any rules or regulations of any securities
         exchange or securities regulatory authority or to conform with general
         usage, all as may be determined by the directors of HOC (on behalf of
         the Trust) executing such Second Debenture in accordance with Section
         2.7 of the Indenture, as conclusively evidenced by their execution of a
         Second Debenture. Each Second Debenture shall additionally bear such
         distinguishing letters and numbers as the Debenture Trustee shall
         approve. Notwithstanding the foregoing, a Second Debenture may be in
         such other form or forms as may, from time to time, be approved by a
         resolution of the directors of HOC, on behalf of the Trust or as
         specified in an Officer's Certificate. The Second Debentures may be
         engraved, lithographed, printed, mimeographed or typewritten or partly
         in one form and partly in another.

         The Second Debentures shall be issued as Global Debentures and the
         Depositary for the Second Debentures shall be The Canadian Depositary
         for Securities Limited, the Global Debentures shall be registered in
         the name of The Canadian Depositary for Securities Limited (or any
         nominee of


                                       6


         the Depositary). No beneficial holder will receive definitive
         certificates representing their interest in Debentures except as
         provided in Section 3.2 of the Indenture. A Global Debenture may be
         exchanged for Second Debentures in registered form that are not Global
         Debentures, or transferred to and registered in the name of a person
         other than the Depository for such Global Debentures or a nominee
         thereof as provided in Section 3.2 of the Indenture.

(j)      Upon and subject to the provisions and conditions of Article 10 of the
         Indenture, the Trust may elect, from time to time, to satisfy its
         Interest Obligation on the Second Debentures (except in respect of
         interest payable as a result of a Holders' Early Redemption or Trust
         Early Redemption) on any Interest Payment Date by delivering Trust
         Units to the Debenture Trustee.

(k)      Within 30 days following the occurrence of a Change of Control, and
         subject to the provisions and conditions of this Section 2.1(k), the
         Trust shall be obligated to offer in writing to each holder of Second
         Debentures (the "OFFER") to purchase the Second Debentures. The terms
         and conditions of such obligation are set forth below:

                  the Second 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 the
                  Offer to purchase all then outstanding Second 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,
                  if any, on such Second Debentures up to, but excluding, the

                  Securities Legislation, be open for acceptance thereof for a
                  period of not less than 35 days and not more than 60 days and
                  shall provide for payment to all Debenture holders who accept
                  the Offer not later than the 60th day after the making of the

                  Second Debentures have been tendered for purchase pursuant to

                  outstanding on the expiration of the Offer at the aggregate
                  Offer Price for such Second Debentures remaining outstanding
                  (the "90% REDEMPTION RIGHT").

         (iii)    Upon receipt of notice that the Trust is acquiring the
                  remaining Second Debentures pursuant to the 90% Redemption
                  Right, 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 Second Debentures
                           effective on the expiry of the Offer at the aggregate
                           Offer Price for such remaining Second Debentures, and
                           shall include a calculation of the amount payable to
                           such holder as payment of the Total Offer Price;


                                       7


                  (B)      each such holder must transfer its Second Debentures
                           to the Debenture Trustee on the same terms as those
                           holders that accepted the Offer and must send its
                           Second 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
                           Second Debentures, the Indenture and this
                           Supplemental 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 redemption pursuant to the 90% Redemption Right,
                           paid the aggregate Offer Price for such Second
                           Debentures to, or to the order of, the Debenture
                           Trustee and thereafter such Second Debentures shall
                           not be considered to be outstanding and the holder
                           shall not have any right except to receive such
                           holder's Offer Price upon surrender and delivery of
                           such holder's Second 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 for each Second
                  Debenture 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 this Section 2.1(k)(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 Second Debentures, the Total Offer Price for each such
                  Second Debenture to which they are entitled on the Trust's
                  purchase or redemption.

         (v)      Second Debentures for which holders have accepted the Offer
                  and Second Debentures which the Trust is redeeming in
                  accordance with this Section 2.1(k) shall become due and
                  payable at the Offer Price for each such Second Debenture 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 Second 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 Second Debentures shall have been deposited as
                  provided in this Section 2.1(k) 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 Second 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.

         (vi)     In case the holder of any Second Debenture to be purchased or
                  redeemed in accordance with this Section 2.1(k) shall fail on
                  or before the date of expiry of the Offer so to surrender such
                  holder's Second Debenture or shall not within such time accept
                  payment of the monies payable, or give such receipt therefor,
                  if any, as the Debenture Trustee may require, such monies 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 monies so


                                       8


                  paid and deposited, upon surrender and delivery up of such
                  holder's Second 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 Second Debentures
                  issued hereunder shall remain so deposited for a period of six
                  years from the date of expiry of the Offer, then such monies,
                  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
                  uncontested 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.

         (vii)    Subject to the provisions above related to Second Debentures
                  purchased in part, all Second Debentures redeemed and paid
                  under this Section 2.1(k) shall forthwith be delivered to the
                  Debenture Trustee and cancelled and no Second Debentures shall
                  be issued in substitution therefor.

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

                             DUE SEPTEMBER 30, 2009

         HARVEST ENERGY TRUST (the "TRUST") for value received hereby
acknowledges itself indebted and, subject to the provisions of the trust
indenture (the "INITIAL INDENTURE") dated as of January 29, 2004 amended and
supplemented by the First Supplemental Indenture dated as of August ___,
2004 (the "FIRST SUPPLEMENTAL INDENTURE" and together with the Initial
Indenture, the "INDENTURE") among the Trust, Harvest Operations Corp. and
Valiant Trust Company (the "DEBENTURE TRUSTEE"), promises to pay to the
registered holder hereof on September 30, 2009 (the "MATURITY DATE") or on such
earlier date as the principal amount hereof may become due in accordance with
the provisions of the Indenture the principal sum of One Hundred Million Dollars
($100,000,000) in lawful money of Canada on presentation and surrender of this
Debenture at the main branch of the Debenture Trustee in Calgary, Alberta or
Toronto, Ontario in accordance with the terms of the Indenture and, subject as
hereinafter provided, to pay interest on the principal amount hereof from the
date hereof, or from the last Interest Payment Date to which interest shall have
been paid or made available for payment hereon, whichever is later, at the rate
of 8.00% per annum, in like money, in arrears in equal (with the exception of
the first interest payment which will include interest from August 10, 2004 to
but excluding March 31, 2005 as set forth below) semi-annual instalments (less
any tax required by law to be deducted) of $40.00 per $1,000 of principal amount
of the Second Debentures on March 31 and September 30 in each year commencing on
March 31, 2005 and the last payment (representing interest payable from the last
Interest Payment Date to, but excluding, the Maturity Date) to fall due on the
Maturity Date and, should the Trust at any time make default in the payment of
any principal or interest, to pay interest on the amount in default at the same
rate, in like money and on the same dates. The first interest payment will
include interest accrued from and including August 10, 2004 to, but excluding
March 31, 2005, which will be equal to $51.06849 for each $1,000 principal
amount of the Second Debentures.

         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 shall, to
the extent of the sum represented thereby (plus the amount of any tax withheld),

                                      A-2


         This Debenture is one of the Series 2, 8.00% Convertible Unsecured
Subordinated Debentures (referred to herein as the "SECOND DEBENTURE") of the
Trust issued or issuable in one or more series under the provisions of the
Indenture. The Second Debentures authorized for issue immediately are limited to
an aggregate principal amount of $100,000,000 in lawful money of Canada.
Reference is hereby expressly made to the Indenture for a description of the
terms and conditions upon which the Second Debentures are or are to be issued
and held and the rights and remedies of the holders of the Second Debentures and
of the Trust and of the Debenture Trustee, all to the same effect as if the
provisions of the Indenture were herein set forth to all of which provisions the
holder of this Second Debenture by acceptance hereof assents. This Second
Debenture is issued subject to the terms of the Indenture, is a summary of, not
intended to be nor constitutes a comprehensive description of, the terms of the
Indenture and in the event of any conflict or inconsistency between the
provisions hereof and the Indenture, the provisions of the Indenture shall
govern.

         The Second Debentures are issuable only in denominations of $1,000 and
integral multiples thereof. Upon compliance with the provisions of the
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 Second Debenture is a denomination in excess of
$1,000, any part which is $1,000 or an integral multiple thereof, of the
principal of this Second Debenture is convertible, at the option of the holder
hereof, upon surrender of this Second 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 Maturity Date or, if this Second Debenture is
called for redemption on or prior to such date, then up to but not after the
close of business on the last Business Day immediately preceding the date
specified for redemption of this Second Debenture, 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 $16.25 (the
"CONVERSION PRICE") per Trust Unit, being a rate of approximately 61.538462
Trust Units for each $1,000 principal amount of Second Debentures, all subject
to the terms and conditions and in the manner set forth in the Indenture. No
Debentures may be converted during the five Business Days preceding and
including March 31 and September 30 in each year, commencing March 31, 2005, as
the registrars of the Debenture Trustee will be closed during such periods. The
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 Indenture. Holders converting their Second
Debentures will receive accrued and unpaid interest thereon. If a Second
Debenture is surrendered for conversion on an Interest Payment Date or during
the five preceding Business Days, the person or persons entitled to receive
Trust Units in respect of the Second Debenture so surrendered for conversion
shall not become the holder or holders of record of such Trust Units until the
Business Day following such Interest Payment Date.

         If the closing of the Acquisition does not take place by the
Termination Time, the Second Debentures may be redeemed at the option of the
holders (the "HOLDERS' EARLY REDEMPTION") in whole (and not in part) for a
period of 10 Business Days from (but excluding) the Termination Date at a
redemption price (the "HOLDERS' EARLY REDEMPTION PRICE") of $1,000 per $1,000
principal amount of Second Debentures and, in addition thereto, at the time of
such redemption, the Trust shall pay to the holder accrued and unpaid interest.
Notice of redemption (the "HOLDERS' EARLY REDEMPTION NOTICE") of the Second
Debentures shall be in the form provided in the First Supplemental Indenture and
must be given to the Trust not less than 10 Business Days from (but excluding)
Termination Date (the "HOLDERS' EARLY REDEMPTION DATE") in the manner provided
for in the Indenture. If the Closing does not take place by the Termination
Time, the provisions of Article 4 of the Indenture (excluding Section 4.6
thereof) apply, MUTATIS MUTANDIS, to the Holders' Early Redemption.


                                      A-3


         If the closing of the Acquisition does not take place by the
Termination Time and provided that following the redemption referred to in this
paragraph (the "TRUST EARLY REDEMPTION") not more than $40,000,000 in principal
amount of Second Debentures are outstanding, the Second Debentures may be
redeemed for cash on a pro rata basis at the option of the Trust in whole or in
part from time to time for a period of 10 Business Days from (but excluding) the
Holders' Early Redemption Date at a redemption price of $1,000 per $1,000
principal amount of Second Debentures and, in addition thereto, at the time of
such redemption, the Trust shall pay to the holder accrued and unpaid interest.
The Redemption Notice for the Second Debentures so to be redeemed shall be in
the form provided in the Indenture Supplement and must be given to holders of
Second Debentures not less than 10 Business Days from (but excluding) the
Holders' Early Redemption Date in the manner provided for in the Indenture. The
provisions of the Indenture shall apply, (excluding Section 4.6 thereof) MUTATIS
MUTANDIS, to the Trust Early Redemption.

         This Second Debenture may also be redeemed at the option of the Trust
on the terms and conditions set out in the Indenture at the redemption price
therein and herein set out provided that, subject to the Holders' Early
Redemption and the Trust Early Redemption, this Second Debenture is not
redeemable on or before September 30, 2007, except in the event of the
satisfaction of certain conditions after a Change of Control has occurred. After
September 30, 2007 and on or prior to September 30, 2008, the Second Debentures
are redeemable at the option of the Trust at a price equal to $1,050 per $1,000
principal amount of Debentures and, in addition thereto, at the time of
redemption, the Trust shall pay to the holder accrued and unpaid interest and
otherwise on the terms and conditions described in the Indenture. After
September 30, 2008 and prior to maturity, the Second Debentures are redeemable
at the option of the Trust at a price equal to $1,025 per $1,000 principal
amount of Debentures and, in addition thereto, at the time of redemption, the
Trust shall pay to the holder accrued and unpaid interest and otherwise on the
terms and conditions described in the Indenture. The Trust may, on notice as
provided in the 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 Second Debentures at a price
equal to 101% of the principal amount of such Second Debentures plus accrued and
unpaid interest (if any) up to, but excluding, the date the Second 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 shall to redeem all the remaining outstanding Second Debentures
on the same date and at the same price.

         If a takeover bid for Second Debentures, within the meaning of the
Applicable Securities Legislation, is made and 90% or more of the principal
amount of all the Second Debentures (other than Second 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 Second 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 Second Debentures.

         The Trust may, on notice as provided in the 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 Second
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 Second
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


                                      A-4


ending on the fifth trading day preceding the Maturity Date.

         The indebtedness evidenced by this Second Debenture, and by all other
Second 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 (including any indebtedness to trade
creditors), whether outstanding at the date of the Indenture or thereafter
created, incurred, assumed or guaranteed.

         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 Second Debenture
or the Indenture.

         The Indenture contains provisions disclaiming any personal liability on
the part of holders of Trust Units, officers and directors of Harvest Operations
Corp. or the trustee, manager and other agents of the Trust in respect of any
obligation or claim arising out of the Indenture or this Debenture.

         This Second Debenture may only be transferred, upon compliance with the
conditions prescribed in the Indenture, in one of the registers to be kept at
the principal office of the Debenture Trustee in Calgary, Alberta or Toronto,
Ontario and in such other place or places and/or by such other registrars (if
any) as the Trust with the approval of the Debenture Trustee may designate. No
transfer of this Second Debenture shall be valid unless made on the register by
the registered holder hereof or his executors or administrators or other legal
representatives, or his or their attorney duly appointed by an instrument in
form and substance satisfactory to the Debenture Trustee or other registrar, and
upon compliance with such reasonable requirements as the Debenture Trustee
and/or other registrar may prescribe and upon surrender of this Second Debenture
for cancellation. Thereupon a new Second Debenture or Second Debentures in the
same aggregate principal amount shall be issued to the transferee in exchange
hereof.

         This Second Debenture shall not become obligatory for any purpose until
it shall have been certified by the Debenture Trustee under the Indenture.

         Capitalized words or expressions used in this Second Debenture shall,
unless otherwise defined herein, have the meaning ascribed thereto in the
Indenture.

         IN WITNESS WHEREOF HARVEST ENERGY TRUST has caused this Debenture to be
signed by its authorized representatives as of the 10th day of August, 2004.
