Immediately upon the giving of notice by the Trustee to Harvest Energy Trust, ExchangeCo and Harvest of the exercise of the Exchange Rights as provided in this Section 5.6, the closing of the transaction of purchase and sale contemplated by the Exchange Rights shall be deemed to have occurred and the holder of such Exchangeable Shares shall be deemed to have transferred to Harvest Energy Trust or ExchangeCo, as determined by Harvest Energy Trust at the time, all of such holder's right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than: (i) the right to receive his proportionate part of the total purchase price therefor, unless the requisite number of Harvest Trust Units is not delivered by Harvest Energy Trust or ExchangeCo, as applicable, to the Trustee within three Business Days of the date of the giving of such notice by the Trustee, in which case the rights of the Beneficiary shall remain unaffected until such Harvest Trust Units are so delivered, by Harvest Energy Trust or ExchangeCo, as applicable; and (ii) the right to receive declared but unpaid dividends in respect of such Exchangeable Shares. Upon delivery to the Trustee of such Harvest Trust Units, the Trustee shall deliver such Harvest Trust Units to such Beneficiary (or to such other persons, if any, properly designated by such Beneficiary). Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the Harvest Trust Units delivered to it pursuant to the Exchange Rights. 5.7 EXERCISE OF EXCHANGE RIGHTS SUBSEQUENT TO RETRACTION In the event that a Beneficiary has exercised its right under Article 4 of the Share Provisions to require Harvest to redeem any or all of the Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and is notified by Harvest pursuant to Section 4.6 of the Share Provisions that Harvest will not be permitted as a result of solvency requirements of applicable law to redeem all such Retracted Shares, and provided that neither Harvest Energy Trust nor ExchangeCo shall have exercised the Retraction Call Right with respect to the Retracted Shares and that the Beneficiary has not revoked the retraction request delivered by the Beneficiary to Harvest pursuant to Section 4.1 of the Share Provisions and provided further that the Trustee has received written notice of same from Harvest Energy Trust, ExchangeCo or Harvest, the retraction request will constitute and will be deemed to constitute notice from the Beneficiary to the Trustee instructing the Trustee to exercise the Exchange Rights with respect to those Retracted Shares that Harvest is unable to redeem. In any such event, Harvest hereby agrees with the Trustee and in favour of the Beneficiary promptly to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Beneficiary to Harvest or to the transfer agent of the Exchangeable Shares (including 11 without limitation, a copy of the retraction request delivered pursuant to Section 4.1 of the Share Provisions) in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise the Exchange Rights with respect to the Retracted Shares that Harvest is not permitted to redeem and will require Harvest Energy Trust or ExchangeCo to purchase such shares in accordance with the provisions of this Article 5. 5.8 STAMP OR OTHER TRANSFER TAXES Upon any sale of Exchangeable Shares to Harvest Energy Trust or ExchangeCo pursuant to the Exchange Rights or the Automatic Exchange Rights, the certificate or certificates representing Harvest Trust Units to be delivered in connection with the payment of the total purchase price therefor shall be issued in the name of the Beneficiary of the Exchangeable Shares so sold or in such names as such Beneficiary may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold; provided, however, that such Beneficiary: (a) shall pay (and none of Harvest Energy Trust, ExchangeCo, Harvest or the Trustee shall be required to pay) any documentary, stamp, transfer or other taxes that may be payable in respect of any transfer involved in the issuance or delivery of such shares to a person other than such Beneficiary, or (b) shall have evidenced to the satisfaction of the Trustee, Harvest Energy Trust, ExchangeCo and Harvest that such taxes, if any, have been paid. 5.9 NOTICE OF INSOLVENCY EVENT, CALL RIGHTS NOT EXERCISED As soon as practicable following the occurrence of either an Exchange Rights Trigger Event or any event that with the giving of notice or the passage of time would be an Exchange Rights Trigger Event, Harvest Energy Trust, ExchangeCo and Harvest shall give written notice thereof to the Trustee. As soon as practicable following the receipt of notice from Harvest Energy Trust, ExchangeCo and Harvest of the occurrence of an Exchange Rights Trigger Event, or upon the Trustee becoming aware of an Exchange Rights Trigger Event, the Trustee will mail to each Beneficiary, at the expense of Harvest Energy Trust, a notice of such Exchange Rights Trigger Event in the form provided by Harvest Energy Trust, which notice shall contain a brief statement of the rights of the Beneficiaries with respect to the Exchange Rights. 5.10 QUALIFICATION OF HARVEST TRUST UNITS Harvest Energy Trust and ExchangeCo covenant that if any Harvest Trust Units to be issued and delivered pursuant to the Exchange Rights or the Automatic Exchange Rights require registration or qualification with or approval of or the filing of any document, including any prospectus or similar document, or the taking of any proceeding with or the obtaining of any order, ruling or consent from any governmental or regulatory authority under any Canadian, federal or provincial law or regulation or pursuant to the rules and regulations of any regulatory authority or the fulfillment of any other Canadian federal or provincial legal requirement before such securities may be issued and delivered by or on behalf of Harvest Energy Trust or ExchangeCo to the initial holder thereof or in order that such securities may be freely traded thereafter (other than any restrictions of general application on transfer by reason of a holder being a "control person" of Harvest Energy Trust for purposes of Canadian provincial securities law), Harvest Energy Trust and ExchangeCo will in good faith expeditiously take all such actions and do all such things as are necessary or desirable to cause such Harvest Trust Units to be and remain duly registered, qualified or approved. Harvest Energy Trust and ExchangeCo will in good faith expeditiously take all such actions and do all such things as are reasonably necessary or desirable to cause all Harvest Trust Units to be delivered pursuant to the Exchange Rights or the Automatic Exchange Rights to be listed, quoted or posted for trading on the Toronto Stock Exchange or such other stock exchanges or quotation systems on which outstanding Harvest Trust Units are then principally listed, quoted or posted for trading at such time. 5.11 HARVEST TRUST UNITS Harvest Energy Trust and ExchangeCo hereby represent, warrant and covenant that the Harvest Trust Units issuable as described herein will be duly authorized and validly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance. 12 5.12 AUTOMATIC EXCHANGE ON LIQUIDATION OF HARVEST ENERGY TRUST (a) Harvest Energy Trust will give the Trustee written notice of each of the following events at the time set forth below: (i) in the event of any determination by the board of directors of Harvest to institute voluntary liquidation, dissolution or winding-up proceedings with respect to Harvest Energy Trust or to effect any other distribution of assets of Harvest Energy Trust among its unitholders for the purpose of winding up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and (ii) as soon as practicable following the earlier of: (A) receipt by Harvest Energy Trust or Harvest of notice of; and (B) Harvest Energy Trust or Harvest otherwise becoming aware of, any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Harvest Energy Trust or to effect any other distribution of assets of Harvest Energy Trust among its unitholders for the purpose of winding up its affairs, in each case where Harvest Energy Trust has failed to contest in good faith any such proceeding commenced in respect of Harvest Energy Trust within 30 days of becoming aware thereof. (b) As soon as practicable following receipt by the Trustee from Harvest Energy Trust of notice of any event (a "Harvest Liquidation Event") contemplated by Section 5.12(a)(i) or 5.12(a)(ii) above, the Trustee will give notice thereof, in the form provided by Harvest Energy Trust, to the Beneficiaries. Such notice shall include a brief description of the Automatic Exchange Rights. (c) In order that the Beneficiaries will be able to participate on a pro rata basis with the holders of Harvest Trust Units in the distribution of assets of Harvest Energy Trust in connection with a Harvest Liquidation Event, on the fifth Business Day prior to the effective date (the "Harvest Liquidation Event Effective Date") of a Harvest Liquidation Event all of the then outstanding Exchangeable Shares shall be automatically exchanged for Harvest Trust Units (the benefit in favour of Beneficiaries of the obligation of Harvest Energy Trust and ExchangeCo to effect the automatic exchange of Exchangeable Shares for Harvest Trust Units as aforesaid is defined as the "Automatic Exchange Rights"). To effect such automatic exchange, Harvest Energy Trust or ExchangeCo shall purchase on the fifth Business Day prior to the Harvest Liquidation Event Effective Date each Exchangeable Share then outstanding and held by Beneficiaries, and each Beneficiary shall sell the Exchangeable Shares held by it at such time, for a purchase price per share determined by multiplying the Current Market Price of a Harvest Trust Unit on the sixth Business Day prior to the Harvest Liquidation Event Effective Date and the Exchange Ratio as at the sixth Business Day prior to the Harvest Liquidation Event Effective Date. Harvest Energy Trust or ExchangeCo shall provide the Trustee with an Officer's Certificate in connection with each automatic exchange setting forth the calculation of the purchase price for each Exchangeable Share. The purchase price for each such Exchangeable Share so purchased may be satisfied only by Harvest Energy Trust or ExchangeCo, as applicable, delivering or causing to be delivered to the Trustee, on behalf of the relevant Beneficiary, that number of Harvest Trust Units equal to the Exchange Ratio as at the sixth Business Day prior to the Harvest Liquidation Event Effective Date, such purchase price to be paid in accordance with Section 5.12(d) (but less any amounts withheld pursuant to Section 5.13). (d) On the fifth Business Day prior to the Harvest Liquidation Event Effective Date: (i) the closing of the transaction of purchase and sale contemplated by the automatic exchange of Exchangeable Shares for Harvest Trust Units shall be deemed to have occurred; (ii) each Beneficiary shall be deemed to have transferred to Harvest Energy Trust or ExchangeCo, as determined by Harvest Energy Trust at that time, all of the Beneficiary's right, title and interest in and to such Beneficiary's Exchangeable Shares and the related interest in the Trust Estate; 13 (iii) any right of each such Beneficiary to receive declared and unpaid dividends from Harvest shall be deemed to be satisfied and discharged; (iv) each such Beneficiary shall cease to be a holder of such Exchangeable Shares; and (v) Harvest Energy Trust or ExchangeCo, as applicable, shall deliver or cause to be delivered to the Trustee on behalf of such Beneficiary the Harvest Trust Units issuable upon the automatic exchange of Exchangeable Shares for Harvest Trust Units. (e) Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the Harvest Trust Units issued pursuant to the automatic exchange of Exchangeable Shares for Harvest Trust Units and the certificates held by the Beneficiary previously representing the Exchangeable Shares exchanged by the Beneficiary with Harvest Energy Trust or ExchangeCo, as applicable, pursuant to such automatic exchange shall thereafter be deemed to represent Harvest Trust Units issued to the Beneficiary pursuant to such automatic exchange. Upon the request of a Beneficiary and the surrender by the Beneficiary of Exchangeable Share certificates deemed to represent Harvest Trust Units, duly endorsed in blank and accompanied by such instruments of transfer as Harvest Energy Trust and ExchangeCo may reasonably require, Harvest Energy Trust or ExchangeCo, as applicable, shall deliver or cause to be delivered to the Beneficiary certificates representing Harvest Trust Units of which the Beneficiary is the holder. 5.13 WITHHOLDING RIGHTS Harvest Energy Trust, ExchangeCo and the Trustee shall be entitled to deduct and withhold from any consideration otherwise payable under this Agreement to any holder of Exchangeable Shares or Harvest Trust Units such amounts as Harvest Energy Trust, ExchangeCo or the Trustee is required to deduct and withhold with respect to such payment under the INCOME TAX ACT (Canada) or any provision of provincial, local or foreign tax law, in each case as amended or succeeded. The Trustee may act on the advice of counsel with respect to such matters. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the holder of the shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, Harvest Energy Trust, ExchangeCo and the Trustee are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Harvest Energy Trust, ExchangeCo or the Trustee, as the case may be, to enable it to comply with such deduction or withholding requirement and Harvest Energy Trust, ExchangeCo or the Trustee shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. 5.14 NON-RESIDENT HOLDERS Notwithstanding anything contained in this Agreement, the obligation of Harvest Energy Trust or ExchangeCo to pay the purchase price for the Exchangeable Shares pursuant to the Exchange Rights or the Automatic Exchange Rights in respect of Exchangeable Shares held by a person whom the transfer agent of the Exchangeable Shares believes is a U.S. Person (as defined in the Share Provisions) or a resident of any foreign country, shall be satisfied by delivering the Harvest Trust Units which would have been received by the Trustee, on behalf of affected holder to the transfer agent and registrar for the Exchangeable Shares who shall sell such Harvest Trust Units on the stock exchange on which the Harvest Trust Units are then listed and, upon such sale, the rights of the affected holder shall be limited to receiving the net proceeds of sale (net of applicable taxes). 5.15 NO FRACTIONAL ENTITLEMENTS Notwithstanding anything contained in this Agreement, including without limitation Article 5, no Beneficiary (or the Trustee as trustee for and on behalf of, and for the use and benefit of a Beneficiary) shall be entitled to and Harvest Energy Trust and ExchangeCo will not deliver fractions of Harvest Trust Units. Where the application of the provisions of this Agreement, including, without limitation, Article 5, would otherwise result in a 14 Beneficiary (or the Trustee, on behalf of the Beneficiary) receiving a fraction of a Harvest Unit, the Beneficiary (or the Trustee on behalf of the Beneficiary) shall be entitled to receive the nearest whole number of Harvest Trust Units. ARTICLE 6 CONCERNING THE TRUSTEE 6.1 POWERS AND DUTIES OF THE TRUSTEE The rights, powers, duties and authorities of the Trustee under this Agreement, in its capacity as Trustee of the Trust, shall include: (a) receipt and deposit of the Special Voting Unit as Trustee for and on behalf of the Beneficiaries in accordance with the provisions of this Agreement; (b) delivery of proxies and distributing materials to Beneficiaries as provided in this Agreement; (c) voting the Beneficiary Votes in accordance with the provisions of this Agreement; (d) receiving the grant of the Exchange Rights and the Automatic Exchange Rights from Harvest Energy Trust and ExchangeCo as Trustee for and on behalf of the Beneficiaries in accordance with the provisions of this Agreement; (e) exercising the Exchange Rights and enforcing the benefit of the Automatic Exchange Rights, in each case in accordance with the provisions of this Agreement, and in connection therewith receiving from Beneficiaries Exchangeable Shares and other requisite documents and distributing to such Beneficiaries Harvest Trust Units and cheques, if any, to which such Beneficiaries are entitled upon the exercise of the Exchange Rights or pursuant to the Automatic Exchange Rights, as the case may be; (f) holding title to the Trust Estate; (g) investing any moneys forming, from time to time, a part of the Trust Estate as provided in this Agreement; (h) taking action on its own initiative or at the direction of a Beneficiary or Beneficiaries to enforce the obligations of Harvest Energy Trust, ExchangeCo and Harvest under this Agreement; and (i) taking such other actions and doing such other things as are specifically provided in this Agreement. In the exercise of such rights, powers, duties and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers, duties and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers, duties and authorities by the Trustee shall be final, conclusive and binding upon all persons. The Trustee in exercising its rights, powers, duties and authorities hereunder shall act honestly and in good faith and with a view to the best interests of the Beneficiaries and shall exercise the care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances. The Trustee shall not be bound to give notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof; nor shall the Trustee be required to take any notice of, or to do, or to take any act, action or proceeding as a result of any default or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notices shall distinctly specify the default or breach desired to be brought to the attention of the Trustee, and in the absence of such notice the Trustee may for all purposes of this Agreement conclusively assume that no default or breach has 15 been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein. 6.2 NO CONFLICT OF INTEREST The Trustee represents to Harvest Energy Trust, ExchangeCo and Harvest that at the date of execution and delivery of this Agreement there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder and the role of the Trustee in any other capacity. The Trustee shall, within 90 days after it becomes aware that such material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Article 9. If, notwithstanding the foregoing provisions of this Section 6.2, the Trustee has such a material conflict of interest, the validity and enforceability of this Agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Trustee contravenes the foregoing provisions of this Section 6.2, any interested party may apply to the Court of Queen's Bench of Alberta for an order that the Trustee be replaced as Trustee hereunder. 6.3 DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC. Harvest Energy Trust, ExchangeCo and Harvest irrevocably authorize the Trustee, from time to time, to: (a) consult, communicate and otherwise deal with the respective registrars and transfer agents, and with any such subsequent registrar or transfer agent, of the Exchangeable Shares and Harvest Trust Units; and (b) requisition, from time to time: (i) from any such registrar or transfer agent any information readily available from the records maintained by it which the Trustee may reasonably require for the discharge of its duties and responsibilities under this Agreement; and (ii) from the transfer agent of Harvest Trust Units, and any subsequent transfer agent of such Harvest Trust Units, the Harvest Trust Unit certificates issuable upon the exercise from time to time of the Exchange Rights and pursuant to the Automatic Exchange Rights. Harvest Energy Trust and Harvest irrevocably authorize their respective registrars and transfer agents to comply with all such requests. Harvest Energy Trust covenants that it will supply its transfer agent with duly executed trust unit certificates for the purpose of completing the exercise from time to time of the Exchange Rights and the Automatic Exchange Rights. 6.4 BOOKS AND RECORDS The Trustee shall keep available for inspection by Harvest Energy Trust, ExchangeCo and Harvest at the Trustee's principal office in Calgary correct and complete books and records of account relating to the Trust created by this Agreement, including without limitation, all relevant data relating to mailings and instructions to and from Beneficiaries and all transactions pursuant to the Special Voting Unit, the Exchange Rights and the Automatic Exchange Rights. On or before January 15, 2004, and on or before January 15th in every year thereafter, so long as this Agreement has not been terminated, the Trustee shall transmit to Harvest Energy Trust, ExchangeCo and Harvest a brief report, dated as of the preceding December 31st , with respect to: (a) the property and funds comprising the Trust Estate as of that date; (b) the number of exercises of the Exchange Rights, if any, and the aggregate number of Exchangeable Shares received by the Trustee on behalf of Beneficiaries in consideration of the issuance of Harvest Trust Units in connection with the Exchange Rights, during the calendar year ended on such December 31st; and (c) any action taken by the Trustee in the performance of its duties under this Agreement which it had not previously reported and which, in the Trustee's opinion, materially affects the Trust Estate. 16 6.5 INCOME TAX RETURNS AND REPORTS The Trustee shall, to the extent necessary, prepare and file on behalf of the Trust appropriate Canadian income tax returns and any other returns or reports as may be required by applicable law or pursuant to the rules and regulations of any securities exchange or other trading system through which the Exchangeable Shares are traded. In connection therewith, the Trustee may obtain the advice and assistance of such experts or advisors as the Trustee considers necessary or advisable (who may be experts or advisors to Harvest Energy Trust, ExchangeCo and Harvest). If requested by the Trustee, Harvest Energy Trust, ExchangeCo and Harvest shall retain qualified experts or advisors for the purpose of providing such tax advice or assistance. 6.6 INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE The Trustee shall exercise any or all of the rights, duties, powers or authorities vested in it by this Agreement at the request, order or direction of any Beneficiary upon such Beneficiary furnishing to the Trustee reasonable funding, security or indemnity against the costs, expenses and liabilities which may be incurred by the Trustee therein or thereby, provided that no Beneficiary shall be obligated to furnish to the Trustee any such security or indemnity in connection with the exercise by the Trustee of any of its rights, duties, powers and authorities with respect to the Voting Rights pursuant to Article 4, subject to Section 6.15, and with respect to the Exchange Rights pursuant to Article 5, subject to Section 6.15, and with respect to the Automatic Exchange Rights pursuant to Article 5. None of the provisions contained in this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the exercise of any of its rights, powers, duties, or authorities unless funded, given security and indemnified as aforesaid. 6.7 ACTION OF BENEFICIARIES No Beneficiary shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this Agreement for the purpose of enforcing any of its rights or for the execution of any trust or power hereunder unless the Beneficiary has requested the Trustee to take or institute such action, suit or proceeding and furnished the Trustee with the funding, security or indemnity referred to in Section 6.6 and the Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Beneficiary shall be entitled to take proceedings in any court of competent jurisdiction such as the Trustee might have taken; it being understood and intended that no one or more Beneficiaries shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by any such action, or to enforce any right hereunder or the Voting Rights, the Exchange Rights or the Automatic Exchange Rights except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be exercised and all proceedings at law shall be instituted, had and maintained by the Trustee, except only as herein provided, and in any event for the equal benefit of all Beneficiaries. 6.8 RELIANCE UPON DECLARATIONS The Trustee shall not be considered to be in contravention of any of its rights, powers, duties and authorities hereunder if, when required, it acts and relies in good faith upon statutory declarations, certificates, opinions or reports furnished pursuant to the provisions hereof or required by the Trustee to be furnished to it in the exercise of its rights, powers, duties and authorities hereunder if such statutory declarations, certificates, opinions or reports comply with the provisions of Section 6.9, if applicable, and with any other applicable provisions of this Agreement. 6.9 EVIDENCE AND AUTHORITY TO TRUSTEE Harvest Energy Trust, ExchangeCo and/or Harvest shall furnish to the Trustee evidence of compliance with the conditions provided for in this Agreement relating to any action or step required or permitted to be taken by Harvest Energy Trust, ExchangeCo and/or Harvest or the Trustee under this Agreement or as a result of any obligation imposed under this Agreement, including, without limitation, in respect of the Voting Rights, the 17 Exchange Rights or the Automatic Exchange Rights and the taking of any other action to be taken by the Trustee at the request of or on the application of Harvest Energy Trust, ExchangeCo and/or Harvest promptly if and when: (a) such evidence is required by any other Section of this Agreement to be furnished to the Trustee in accordance with the terms of this Section 6.9; or (b) the Trustee, in the exercise of its rights, powers, duties and authorities under this Agreement, gives Harvest Energy Trust, ExchangeCo and/or Harvest written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice. Such evidence shall consist of an Officer's Certificate of ExchangeCo and/or Harvest or a statutory declaration or a certificate made by persons entitled to sign an Officer's Certificate stating that any such condition has been complied with in accordance with the terms of this Agreement. Whenever such evidence relates to a matter other than the Voting Rights, the Exchange Rights or the Automatic Exchange Rights or the taking of any other action to be taken by the Trustee at the request or on the application of Harvest Energy Trust, ExchangeCo and/or Harvest, and except as otherwise specifically provided herein, such evidence may consist of a report or opinion of any solicitor, attorney, auditor, accountant, appraiser, valuer, engineer or other expert or any other person whose qualifications give authority to a statement made by him, provided that if such report or opinion is furnished by a director, officer or employee of ExchangeCo and/or Harvest it shall be in the form of an Officer's Certificate or a statutory declaration. Each statutory declaration, Officer's Certificate, opinion or report furnished to the Trustee as evidence of compliance with a condition provided for in this Agreement shall include a statement by the person giving the evidence: (c) declaring that he or she has read and understands the provisions of this Agreement relating to the condition in question; (d) describing the nature and scope of the examination or investigation upon which he or she based the statutory declaration, certificate, statement or opinion; and (e) declaring that he or she has made such examination or investigation as he or she believes is necessary to enable him or her to make the statements or give the opinions contained or expressed therein. 6.10 EXPERTS, ADVISERS AND AGENTS The Trustee may: (a) in relation to these presents act and rely on the opinion or advice of or information obtained from any solicitor, attorney, auditor, accountant, appraiser, valuer, engineer or other expert, whether retained by the Trustee or by Harvest Energy Trust, ExchangeCo and/or Harvest or otherwise, and may retain or employ such assistants as may be necessary to the proper discharge of its powers and duties and determination of its rights hereunder and may pay proper and reasonable compensation for all such legal and other advice or assistance as aforesaid; and (b) employ such agents and other assistants as it may reasonably require for the proper determination and discharge of its powers and duties hereunder, and may pay reasonable remuneration for all services performed for it (and shall be entitled to receive reasonable remuneration for all services performed by it) in the discharge of the trusts hereof and compensation for all disbursements, costs and expenses made or incurred by it in the discharge of its duties hereunder and in the management of the Trust. 6.11 INVESTMENT OF MONEYS HELD BY TRUSTEE Unless otherwise provided in this Agreement, any moneys held by or on behalf of the Trustee which under the terms of this Agreement may or ought to be invested or which may be on deposit with the Trustee 18 or which may be in the hands of the Trustee may be invested and reinvested in the name or under the control of the Trustee, in trust for Harvest, in securities in which, under the laws of the Province of Alberta, trustees are authorized to invest trust moneys, provided that such securities are stated to mature within two years after their purchase by the Trustee, and the Trustee shall so invest such moneys on the written direction of Harvest. Pending the investment of any moneys as hereinbefore provided, such moneys may be deposited in the name of the Trustee in any chartered bank in Canada (including an affiliate of the Trustee) or, with the consent of Harvest, in the deposit department of the Trustee or any other loan or trust company authorized to accept deposits under the laws of Canada or any province thereof at the rate of interest then current on similar deposits, and the Trustee shall be entitled to receive a fee from such bank, loan or trust company for so depositing such moneys. 6.12 TRUSTEE NOT REQUIRED TO GIVE SECURITY The Trustee shall not be required to give any bond or security in respect of the execution of the trusts, rights, duties, powers and authorities of this Agreement or otherwise in respect of the premises. 6.13 TRUSTEE NOT BOUND TO ACT ON REQUEST Except as in this Agreement otherwise specifically provided, the Trustee shall not be bound to act in accordance with any direction or request of Harvest Energy Trust, ExchangeCo and/or Harvest or of the directors thereof until a duly authenticated copy of the instrument or resolution containing such direction or request shall have been delivered to the Trustee, and the Trustee shall be empowered to act upon any such copy purporting to be authenticated and believed by the Trustee to be genuine. 6.14 AUTHORITY TO CARRY ON BUSINESS The Trustee represents to Harvest Energy Trust, ExchangeCo and/or Harvest that at the date of execution and delivery by it of this Agreement it is authorized to carry on the business of a trust company in each of the Provinces of Canada but if, notwithstanding the provisions of this Section 6.14, it ceases to be so authorized to carry on business, the validity and enforceability of this Agreement and the Voting Rights, the Exchange Rights and the Automatic Exchange Rights shall not be affected in any manner whatsoever by reason only of such event but the Trustee shall, within 90 days after ceasing to be authorized to carry on the business of a trust company in any Province of Canada, either become so authorized or resign in the manner and with the effect specified in Article 9. 6.15 CONFLICTING CLAIMS If conflicting claims or demands are made or asserted with respect to any interest of any Beneficiary in any Exchangeable Shares, including any disagreement between the heirs, representatives, successors or assigns succeeding to all or any part of the interest of any Beneficiary in any Exchangeable Shares, resulting in conflicting claims or demands being made in connection with such interest, then the Trustee shall be entitled, at its sole discretion, to refuse to recognize or to comply with any such claims or demands. In so refusing, the Trustee may elect not to exercise any portion of the Voting Rights, Exchange Rights or Automatic Exchange Rights subject to such conflicting claims or demands and, in so doing, the Trustee shall not be or become liable to any person on account of such election or its failure or refusal to comply with any such conflicting claims or demands. The Trustee shall be entitled to continue to refrain from acting and to refuse to act until: (a) the rights of all adverse claimants with respect to the Voting Rights, Exchange Rights or Automatic Exchange Rights subject to such conflicting claims or demands have been adjudicated by a final judgment of a court of competent jurisdiction; or (b) all differences with respect to the Voting Rights, Exchange Rights or Automatic Exchange Rights subject to such conflicting claims or demands have been conclusively settled by a valid written agreement binding on all such adverse claimants, and the Trustee shall have been furnished with an executed copy of such agreement certified to be in full force and effect. 19 If the Trustee elects to recognize any claim or comply with any demand made by any such adverse claimant, it may in its discretion require such claimant to furnish such surety bond or other security satisfactory to the Trustee as it shall deem appropriate to fully indemnify it as between all conflicting claims or demands. 6.16 ACCEPTANCE OF TRUST The Trustee hereby accepts the Trust created and provided for by and in this Agreement and agrees to perform the same upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various persons who shall from time to time be Beneficiaries, subject to all the terms and conditions herein set forth. ARTICLE 7 COMPENSATION 7.1 FEES AND EXPENSES OF THE TRUSTEE Harvest Energy Trust, ExchangeCo and Harvest jointly and severally agree to pay the Trustee reasonable compensation for all of the services rendered by it under this Agreement and will reimburse the Trustee for all reasonable expenses (including, but not limited to, taxes other than taxes based on the net income of the Trustee, fees paid to legal counsel and other experts and advisors (provided however that the payment of fees to legal counsel and other experts and advisors shall be required to be pre-approved by Harvest) and travel expenses) and disbursements, including the cost and expense of any suit or litigation of any character and any proceedings before any governmental agency reasonably incurred by the Trustee in connection with its duties under this Agreement; provided that Harvest Energy Trust, ExchangeCo and Harvest shall have no obligation to reimburse the Trustee for any expenses or disbursements paid, incurred or suffered by the Trustee in any suit or litigation in which the Trustee is determined to have acted in bad faith or with gross negligence, recklessness or willful misconduct. ARTICLE 8 INDEMNIFICATION AND LIMITATION OF LIABILITY 8.1 INDEMNIFICATION OF THE TRUSTEE Harvest Energy Trust, ExchangeCo and Harvest jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees, shareholders and agents appointed and acting in accordance with this Agreement (collectively, the "Indemnified Parties") against all claims, losses, damages, reasonable costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel) which, without fraud, gross negligence, recklessness, willful misconduct or bad faith on the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason or as a result of the Trustee's acceptance or administration of the Trust, its compliance with its duties set forth in this Agreement, or any written or oral instruction delivered to the Trustee by Harvest Energy Trust, ExchangeCo or Harvest pursuant hereto. Harvest Energy Trust, ExchangeCo and Harvest shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal process giving information as to the nature and basis of the claim, provided that the omission to so notify Harvest Energy Trust, ExchangeCo and Harvest shall not relieve Harvest Energy Trust, ExchangeCo and Harvest of any liability which any of them may have to any Indemnified Party except and only to the extent that any such delay in or failure to give notice as herein required prejudices the defence of such claim or action or results in any increase in the liability which Harvest Energy Trust, ExchangeCo and Harvest have under this indemnity. Subject to (ii) below, Harvest Energy Trust, ExchangeCo and Harvest shall be entitled to participate at their own expense in the defense and, if Harvest Energy Trust, ExchangeCo and Harvest so elect at any time after receipt of such notice, any of them may assume the defense of any suit brought to enforce any such claim in which case, the Trustee shall have the right to employ separate counsel in any such suit and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Trustee unless: (i) the employment 20 of such counsel has been authorized by Harvest Energy Trust, ExchangeCo and Harvest; or (ii) the named parties to any such suit include both the Trustee and Harvest Energy Trust, ExchangeCo or Harvest and the Trustee shall have been advised by counsel acceptable to Harvest Energy Trust, ExchangeCo or Harvest that there may be one or more legal defenses available to the Trustee that are different from or in addition to those available to Harvest Energy Trust, ExchangeCo or Harvest and that, in the judgment of such counsel, would present a conflict of interest were a joint representation to be undertaken (in which case Harvest Energy Trust, ExchangeCo and Harvest shall not have the right to assume the defense of such suit on behalf of the Trustee but shall be liable to pay the reasonable fees and expenses of counsel for the Trustee). This indemnity shall survive the termination of this Agreement and the resignation or removal of the Trustee. 8.2 LIMITATION OF LIABILITY The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on any investment of funds pursuant to this Agreement, except to the extent that such loss is principally and directly attributable to the gross fraud, negligence, recklessness, willful misconduct or bad faith on the part of the Trustee. ARTICLE 9 CHANGE OF TRUSTEE 9.1 RESIGNATION The Trustee, or any trustee hereafter appointed, may at any time resign by giving written notice of such resignation to Harvest Energy Trust, ExchangeCo and Harvest specifying the date on which it desires to resign, provided that such notice shall not be given less than thirty (30) days before such desired resignation date unless Harvest Energy Trust, ExchangeCo and Harvest otherwise agree and provided further that such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by the successor trustee. Upon receiving such notice of resignation, Harvest Energy Trust, ExchangeCo and Harvest shall promptly appoint a successor trustee, which shall be a corporation organized and existing under the laws of Canada and authorized to carry on the business of a trust company in all provinces of Canada, by written instrument in duplicate, one copy of which shall be delivered to the resigning trustee and one copy to the successor trustee. Failing the appointment and acceptance of a successor trustee, a successor trustee may be appointed by order of a court of competent jurisdiction upon application of one or more of the parties to this Agreement. If the retiring trustee is the party initiating an application for the appointment of a successor trustee by order of a court of competent jurisdiction, Harvest Energy Trust, ExchangeCo and Harvest shall be jointly and severally liable to reimburse the retiring trustee for its legal costs and expenses in connection with same. 9.2 REMOVAL The Trustee, or any trustee hereafter appointed, may (provided a successor trustee is appointed) be removed at any time on not less than 30 days' prior notice by written instrument executed by Harvest Energy Trust, ExchangeCo and Harvest, in duplicate, one copy of which shall be delivered to the trustee so removed and one copy to the successor trustee. 9.3 SUCCESSOR TRUSTEE (a) Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to Harvest Energy Trust, ExchangeCo and Harvest and to its predecessor trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with the like effect as if originally named as trustee in this Agreement. However, on the written request of Harvest Energy Trust, ExchangeCo and Harvest or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of this Agreement, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act.
