(a)

any information or statement (except any information or statement relating solely to the Underwriters) in the Preliminary Prospectus, the Prospectus, any Prospectus Amendment, any Subsequent Disclosure Document or in any other document or material filed or delivered pursuant hereto being or being alleged to be a misrepresentation or untrue, or any omission or alleged omission to state therein any fact or information (except facts or information relating solely to the Underwriters) required to be stated therein or necessary to make any of the statements therein not misleading in light of the circumstances in which they were made;

- 21 -

(b)	any order made or any, investigation or proceeding commenced or threatened by any securities regulatory or other authority based upon any untrue statement, omission or misrepresentation or alleged untrue statement, omission or misrepresentation (except a statement, omission or misrepresentation relating solely to the Underwriters) in the Preliminary Prospectus, the Prospectus or in any Prospectus Amendment or in any other document or material filed or delivered pursuant hereto, preventing or restricting the trading in or the distribution of the Offered Units in any of the Provinces;

(c)	the breach of any representations, warranties or covenants of the Trust or Harvest Operations contained herein or delivered pursuant hereto; or

(d)	the Trust not complying with any requirement of applicable Securities Laws or the by-laws, rules or policies of the Toronto Stock Exchange in connection with the transaction contemplated herein;

provided the Indemnitors shall cease to be liable to an Indemnified Party in any such case if and to the extent that a court of competent jurisdiction determines, in a final judgment in a proceeding to which such Indemnified Party was a party, that any such liabilities, claims, demands, losses, costs, damages and expenses were caused by or resulted from the negligence, fraud or willful misconduct of such Indemnified Party or the breach by any such Indemnified Party of any of its covenants herein provided for or of applicable Securities Laws or other laws in connection with the transaction contemplated herein.

12.2 In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in section 12.1 is due in accordance with its terms but is held by a court to be unavailable, in whole or in part, for any reason to an Indemnified Party in respect of any liabilities, claims, demands, losses, costs, damages and expenses referred to therein, the Indemnitors shall contribute to the amount paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by such Indemnified Party as a result of such liabilities, claims, demands, losses, costs, damages and expenses:

(b)	in such proportion as is appropriate to reflect the relative benefits received by the Indemnitors on the one hand and the Underwriters on the other from the distribution of the Offered Units; or

(c)	if the allocation provided by clause (a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (a) above but also the relative fault of the Indemnitors on the one hand and the Underwriters on the other in connection with the matters or things referred to in section 12.1 which resulted in such liabilities, claims, demands, losses, costs, damages or expenses, as well as any other relevant equitable considerations;

provided that the Underwriters shall not in any event be liable to contribute, in the aggregate, any amount in excess of the Underwriting Fee or any portion thereof actually received. The relative benefits received by the Indemnitors on the one hand and the Underwriters on the other shall be deemed to be in the same ratio as the total proceeds from the distribution of the Offered Units (net of the Underwriting Fee payable to the Underwriters but before deducting expenses) received by the Trust is to the Underwriting Fee received by the Underwriters. The relative fault of the Indemnitors on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the matters or things referred to in section 12.1 which resulted in such liabilities, claims, demands, losses, costs, damages and expenses relate to information supplied by or steps or actions taken or done or not taken or done by or on behalf of the Indemnitors or to information supplied by or steps or actions taken or done or not taken or done by or on behalf of the Underwriters and the relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission or misrepresentation, or other matter or thing referred to in section 12.1. The parties agree that it would not be just and equitable if contribution pursuant to this section 12.2 were determined by any method of allocation which does not take into account the equitable considerations referred to above in this section 12.2.

- 22 -

12.3 If any matter or thing contemplated by this section 12 shall be asserted against any Indemnified Party, the Indemnified Party concerned shall promptly notify the Indemnitors and the Underwriters of the nature of such claim (provided that any failure to so notify promptly shall relieve the Indemnitors of liability under this section 12 only to the extent that such failure prejudices the ability of the Indemnitors to defend such claim), and the Indemnitors shall, subject as hereinafter provided, be entitled (but not required) to assume the defence of any suit or proceeding (including any governmental or regulatory investigation or proceeding) brought to enforce such claim. Any such defence shall be through legal counsel acceptable to the Indemnified Party (whose acceptance shall not be unreasonably withheld) and no admission of liability or settlement shall be made by the Indemnitors or any Indemnified Party in respect of any Indemnified Party without, in each case, the prior written consent of the other party, such consent not to be unreasonably withheld. An Indemnified Party shall have the right to employ separate counsel in any such suit and participate in the defence thereof but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless: (i) the Indemnitors fail to assume the defence of such suit on behalf of the Indemnified Party within a reasonable period of time; or (ii) the employment of such counsel has been authorized in writing by the Indemnitors; or (iii) the named parties to any such suit or proceeding include both the Indemnified Party on the one hand and any of the Indemnitors on the other and the Indemnified Party shall have received a written opinion from counsel acceptable to the Indemnitors, acting reasonably, that representation of both parties by the same counsel would be inappropriate due to the actual or potential differing interests between them (in which case, if such Indemnified Party notifies the Indemnitors in writing that it elects to employ separate counsel at the expense of the Indemnitors, the Indemnitors shall not have the right to assume the defence of such suit or proceeding on behalf of the Indemnified Party and shall be liable to pay the reasonable fees and expenses of counsel for the Indemnified Party, it being understood, however, that the Indemnitors shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate law firm (in addition to any local counsel) for all such Indemnified Parties). None of the Indemnitors shall be liable for any settlement of any action or suit effected without its written consent. It is the intention of the Indemnitors to constitute each of the Underwriters as trustees for the Underwriters' respective directors, officers, employees, shareholders and agents of the covenants of the Indemnitors under section 12.1 with respect to the Underwriters' directors, officers, employees, shareholders and agents, and the Underwriters agree to accept such trust and to hold and enforce such covenants on behalf of such persons.

12.4 The rights provided in this section 12 shall be in addition to and not in derogation of any other right which the Underwriters may have by statute or otherwise at law.

13. OBLIGATIONS OF THE UNDERWRITERS

13.1 The obligations of the Underwriters to purchase the Offered Units at the Closing Time or the Additional Closing Time, as applicable, shall be several and not joint in that each Underwriter shall be obligated to purchase only the percentage of the Offered Units respectively set out opposite its name below:

In the event that such right is not exercised, the Underwriter or Underwriters which are able and willing to purchase shall be relieved of all obligations to the Trust.

13.2 Nothing in this section 13 shall obligate the Trust to sell to one or any of the Underwriters less than all of the Firm Units or Over-Allotment Units, as applicable, or shall relieve any Underwriter in default from liability to the Trust or Harvest Operations or to any non-defaulting Underwriter in respect of its default hereunder. In the event of a termination by the Trust or Harvest Operations of their obligations under this agreement, there shall be no further liability on the part of the Trust or Harvest Operations to the Underwriters except in respect of any liability which may have arisen or may thereafter arise under sections 12 and 14.

14.2 If the public offering of the Offered Units is not completed due to any reason whatsoever (unless such failure to complete is a result of a breach or default of the Underwriters), including, without limitation, the inability or unwillingness of the Trust or due to any of the Underwriters exercising the termination rights set forth herein, the Trust shall be responsible for the fees and expenses of counsel to the Underwriters (on a solicitor and his own client basis) and the out-of-pocket expenses incurred by the Underwriters, including their expenses related to due diligence investigations (including the fees and expenses of any experts retained by the Underwriters in connection therewith), information meetings and travel (the "Underwriters' Expenses").

14.3 If the public offering of the Offered Units is completed, the Underwriters shall be responsible for the Underwriters' Expenses.

- 24 -

14.4 If the Underwriters are entitled to reimbursement for Underwriters' Expenses hereunder, the Trust shall reimburse the Underwriters upon presentation of reasonable evidence of such expenses. The Underwriters shall present reasonable evidence of the Underwriters' Expenses to the Trust as soon as is practicable following the termination of the public offering and the Trust shall reimburse the Lead Underwriter, on behalf of the Underwriters, therefor, in accordance with paragraph 14.2, within 30 days of receipt of reasonable evidence of the Underwriters' Expenses.

6.	All purchasers of the Offered Units in the United States shall be informed by an Underwriter or its U.S. registered broker-dealer affiliate that the Offered Units have not been and will not be registered under the U.S. Securities Act and are being offered and sold to such purchasers in reliance on an exemption from the registration requirements of the U.S. Securities Act.

The U.S. Memorandum shall set forth the following:

IF THESE SECURITIES ARE BEING SOLD IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT AT A TIME WHEN HARVEST ENERGY TRUST IS A "FOREIGN ISSUER" AS DEFINED IN REGULATION S, A NEW CERTIFICATE BEARING NO LEGEND MAY BE OBTAINED FROM VALIANT TRUST COMPANY UPON DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED DECLARATION, IN A FORM SATISFACTORY TO VALIANT TRUST COMPANY AND HARVEST ENERGY TRUST, TO THE EFFECT THAT THE SALE OF THE SECURITIES REPRESENTED HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT. If the Trust Units are being sold in compliance with the requirements of Rule 904 of Regulation S at a time when the Trust is a "foreign issuer" as defined in Regulation S, the legend may be removed by providing a declaration to Valiant Trust Company substantially in the form of Exhibit II hereto, or as the Trust may prescribe from time to time.

- 5 -

			If the Trust Units are being sold under Rule 144 of the U.S. Securities Act, the legend may be removed by delivery to Valiant Trust Company of an opinion of counsel of recognized standing and reasonably satisfactory to the Trust, to the effect that such legend is no longer required under the U.S. Securities Act or state securities laws;

(d)	we agree that if we decide to offer, sell or otherwise transfer or pledge all or any part of the Trust Units, we will not offer, sell or otherwise transfer or pledge any of such securities (other than pursuant to an effective registration statement under the Securities Act), directly or indirectly unless:

		and in the case of subparagraph (iv) or (v), we have furnished to the Trust an opinion of counsel, of recognized standing reasonably satisfactory to the Trust, to that effect;

	(e)	we understand and acknowledge that the Trust Units are "restricted securities" as defined in Rule 144 under the Securities Act, and upon the original issuance thereof, and until such time as the same is no longer required under applicable requirements of the Securities Act or state securities laws, the certificates representing the Trust Units, and all certificates issued in exchange therefor or in substitution thereof, shall bear on the face of such certificates the following legend: THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR STATE SECURITIES LAWS.
