If any claim contemplated by Subsection 10(a) shall be asserted against any of the persons or corporations in respect of which indemnification is or might reasonably be considered to be provided for in such paragraphs, such person or corporation (the "Indemnified Person") shall notify the Trust, POT and the Administrator (collectively the "Indemnifying Parties") (provided that failure to so notify the Indemnifying Parties of the nature of such claim in a timely fashion shall relieve the Indemnifying Parties of liability hereunder only if and to the extent that such failure materially prejudices the Indemnifying Parties' ability to defend such claim) as soon as possible of the nature of such claim and the Indemnifying Parties shall be entitled (but not required) to assume the defence of any suit brought to enforce such claim, provided however, that the defence shall be through legal counsel selected by the Indemnifying Parties and acceptable to the Indemnified Person acting reasonably and that no settlement or admission of liability may be made by the Indemnifying Parties or the Indemnified Person without the prior written consent of the other, such consent not to be unreasonably withheld. The Indemnified Person shall have the right to retain its own counsel in any proceeding relating to a claim contemplated by Subsection 10(a) if:

the Indemnified Person has been advised by counsel that there may be a reasonable legal defense available to the Indemnified Person which is different from or additional to a defense available to an Indemnifying Party and that representation of the Indemnified Person and any one or more of the Indemnifying Parties by the same counsel would be inappropriate due to the actual or potential differing interests between them (in which case the Indemnifying Parties shall not have the right to assume the defense of such proceedings on the Indemnified Person's behalf);

the Indemnifying Parties shall not have taken the defense of such proceedings and employed counsel within ten (10) days after notice has been given to the Indemnifying Parties of commencement of such proceedings; or

the employment of such counsel has been authorized by the Indemnifying Parties in connection with the defense of such proceedings;

and, in any such event, the reasonable fees and expenses of such Indemnified Person's counsel (on a solicitor and his client basis) shall be paid by the Indemnifying Parties, provided that the Indemnifying Parties 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 Persons.

Each of the Indemnifying Parties hereby waives its rights to recover contribution from the Underwriters with respect to any liability of the Indemnifying Party by reason of or arising out of any misrepresentation in the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record provided, however, that such waiver shall not apply in respect of liability caused or incurred by reason of any misrepresentation which is based upon information relating solely to the Underwriters contained in such document and furnished to the Trust by the Underwriters expressly for inclusion in the Preliminary Prospectus, the Prospectus or any Supplementary Material.

If any legal proceedings shall be instituted against an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, or if any regulatory authority or stock exchange shall carry out an investigation of an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, and, in either case, any Indemnified Person is required to testify, or respond to procedures designed to discover information, in connection with or by reason of the services performed by the Underwriters hereunder, the Indemnified Persons may employ their own legal counsel and the Indemnifying Parties shall pay and reimburse the Indemnified Persons for the reasonable fees, charges and disbursements (on a full indemnity basis) of such legal counsel, the other expenses reasonably incurred by the Indemnified Persons in connection with such proceedings or investigation and a fee at the normal per diem rate for any director, officer or employee of the Underwriters involved in the preparation for or attendance at such proceedings or investigation.

The rights and remedies of the Indemnified Persons set forth in Sections 10, 11 and 12 hereof are to the fullest extent possible in law cumulative and not alternative and the election by any Underwriter or other Indemnified Person to exercise any such right or remedy shall not be, and shall not be deemed to be, a waiver of any other rights and remedies.

The Indemnifying Parties hereby acknowledge that the Underwriters are acting as agents for the Underwriters' respective agents, directors, officers, shareholders and employees under this Section 10 and under Section 11 with respect to all such agents, directors, officers, shareholders and employees.

The Indemnifying Parties waive any right they may have of first requiring an Indemnified Person to proceed against or enforce any other right, power, remedy or security or claim or to claim payment from any other person before claiming under this indemnity. It is not necessary for an Indemnified Person to incur expense or make payment before enforcing such indemnity.

The rights of indemnity contained in this Section 10 shall not apply if the Indemnifying Parties have complied with the provisions of Sections 4 and 5 (or the Underwriters have otherwise agreed

to waive compliance therewith) and the person asserting any claim contemplated by this Section 10 was not provided with a copy of the Prospectus or any amendment to the Prospectus or other document which corrects any misrepresentation or alleged misrepresentation which is the basis of such claim and which was required, under Applicable Securities Laws, to be delivered to such person by the Underwriters.

If the Indemnifying Parties have assumed the defense of any suit brought to enforce a claim hereunder, the Indemnified Person shall provide the Indemnifying Parties copies of all documents and information in its possession pertaining to the claim, take all reasonable actions necessary to preserve its rights to object to or defend against the claim, consult and reasonably cooperate with the Indemnifying Parties in determining whether the claim and any legal proceeding resulting therefrom should be resisted, compromised or settled and reasonably cooperate and assist in any negotiations to compromise or settle, or in any defense of, a claim undertaken by the Indemnifying Parties.

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this agreement is due in accordance with its terms but is, for any reason, held by a court to be unavailable from one or more of the Indemnifying Parties on grounds of policy or otherwise, the Indemnifying Parties and the party or parties seeking indemnification shall contribute to the aggregate liabilities, claims, demands, losses (other than losses of profit in connection with the distribution of the Offered Securities), costs (including, without limitation, reasonable legal fees and disbursements on a full indemnity basis), damages and expenses to which they may be subject or which they may suffer or incur:

in such proportion as is appropriate to reflect the relative benefit received by the Indemnifying Parties on the one hand, and by the Underwriters on the other hand, from the offering of the Offered Securities; or

if the allocation provided by Subsection 11(a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Subsection 11(a) above but also to reflect the relative fault of the Underwriters on the one hand, and the Indemnifying Parties, on the other hand, in connection with the statements, commissions or omissions or other matters which resulted in such liabilities, claims, demands, losses, costs, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Indemnifying Parties, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion that the total proceeds of the offering received by the Indemnifying Parties (net of fees but before deducting expenses) bear to the fees received by the Underwriters. In the case of liability arising out of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, the relative fault of the Indemnifying Parties, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference, among other things, to whether the misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 10 relates to information supplied or which ought to have been supplied by, or steps or actions taken or done on behalf of or which ought to have been taken or done on behalf of, one or more of the Indemnifying Parties or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 10.

The amount paid or payable by an Indemnified Person as a result of liabilities, claims, demands, losses (other than losses of profit in connection with the distribution of the Offered Securities), costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) referred to above shall, without limitation, include any legal or other expenses reasonably incurred by the Indemnified Person in connection with investigating

or defending such liabilities, claims, demands, losses, costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) whether or not resulting in any action, suit, proceeding or claim.

Each of the Indemnifying Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this agreement were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraphs. The rights to contribution provided in this Section 11 shall be in addition to, and without prejudice to, any other right to contribution which the Underwriters or other Indemnified Persons may have.

Any liability of the Underwriters under this Section 11 shall be limited to the amount actually received by the Underwriters under Section 2.

Whether or not the transactions contemplated herein shall be completed, all costs and expenses (including applicable goods and services tax) of or incidental to the transactions contemplated hereby including, without limitation, those relating to the distribution of the Offered Receipts and the Offered Debentures shall be borne by the Trust including, without limitation, all costs and expenses of or incidental to the preparation, filing, reproduction (including the commercial copies thereof) and translation of the Preliminary Prospectus, the Prospectus, the Subscription Receipt Agreement, the Indenture, any Supplementary Material and the "greensheet", if any, and the delivery thereof to the Underwriters, the fees and expenses of the Trust's counsel, the fees and expenses of agent counsel retained by the Trust or the Trust's counsel, the fees and expenses of the Trust's transfer agent, auditors, engineers and other outside consultants, all stock exchange listing fees, the reasonable fees and expenses of the Underwriters' counsel (unless the transactions contemplated herein are completed, in which case the reasonable fees and expenses of the Underwriters' counsel shall be borne by the Underwriters), all reasonable expenses incurred by the Underwriters, the cost of preparing record books for all of the parties to this agreement and their respective counsel and all other costs and expenses relating to this transaction.

In addition and without prejudice to any other remedies which may be available to the Underwriters, or any of them, the Underwriters may, without liability, terminate their obligations hereunder, by written notice to the Trust, in the event that after the date hereof and at or prior to the Closing Time:

any order to cease or suspend trading in any securities of the Trust or prohibiting or restricting the distribution of any of the Offered Securities or the Trust Units issuable pursuant to the Offered Receipts is made, or proceedings are announced, commenced or threatened for the making of any such order, by any securities commission or similar regulatory authority, the TSX or any other competent authority, and has not been rescinded, revoked or withdrawn;

there should occur or commence, or be announced or threatened, any inquiry, action, suit, investigation or other proceeding (whether formal or informal); or any order is issued by any governmental authority or exchange; or any law or regulation is promulgated, changed or announced; or any announcement of any change or proposed change in the income tax laws of Canada or the interpretation or administration thereof; which in the opinion of the Underwriters or any one of them, acting reasonably, is expected to prevent or materially restrict the trading in or the distribution of the Offered Securities, the Trust Units issuable pursuant to the Offered Receipts or any other securities of the Trust or would reasonably be expected to have a material adverse effect on the market price or value of the Trust Units or other securities of the Trust;

there shall have occurred any material change (actual, anticipated, contemplated or threatened, financial or otherwise), as determined by the Underwriters or any one of them in their sole discretion, acting reasonably, in the senior management of the Administrator, or in the business, affairs, operations, assets, liabilities (contingent or otherwise), capital or condition (financial or otherwise), business or business prospects of the Trust, on a consolidated basis, or the respective properties, assets, liabilities or obligations (absolute, accrued, contingent or otherwise) of the Trust, on a consolidated basis, or any change in a material fact, or the Underwriters become aware of any undisclosed material information, in any case which in the Underwriters' opinion, could reasonably be expected to have a significant adverse effect on the market price or value of the Offered Receipts, the Offered Debentures, the Trust Units issuable pursuant to the Offered Receipts or any other securities of the Trust or the investment quality or marketability of the Offered Receipts, the Offered Debentures, the Trust Units issuable pursuant to the Offered Receipts or any other securities of the Trust;

there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence, any law or regulation or any other occurrence of any nature whatsoever which, in the sole opinion of the Underwriters or any one of them, seriously adversely affects, or involves, or will seriously adversely affect, or involve, the financial markets or the business, operations or affairs of the Trust, on a consolidated basis;

the Underwriters shall become aware of any adverse material change with respect to the Trust, on a consolidated basis, which had not been publicly disclosed or disclosed in writing to the Underwriters at or prior to the date hereof;

the final MRRS decision document referred to in Section 4(b)(iii)(C) has not been issued effective April 8, 2005 (or such other time and/or later date as the Administrator and the Underwriters may agree);

the Trust, POT or the Administrator shall be in breach or default under or non-compliance with any representation, warranty, term or condition of this agreement, in any material respect; or

The Underwriters, or any of them, may exercise any or all of the rights provided for in Subsection 13(a) or Sections 14 or 18 notwithstanding any material change, change, event or state of facts and (except where the Underwriter purporting to exercise any of such rights is in breach of its obligations under this agreement) notwithstanding any act or thing taken or done by the Underwriters or any inaction by the Underwriters, whether before or after the occurrence of any material change, change, event or state of facts including, without limitation, any act of the Underwriters related to the offering or continued offering of the Offered Securities for sale and any act taken by the Underwriters in connection with any amendment to the Prospectus (including the execution of any amendment or any other Supplementary Material) and the Underwriters shall only be considered to have waived or be estopped from exercising or relying upon any of their rights under or pursuant to Subsection 13(a) or Sections 14 or 18 if such waiver or estoppel is in writing and specifically waives or estops such exercise or reliance.

Any termination pursuant to the terms of this agreement shall be effected by notice in writing delivered to the Trust, provided that no termination shall discharge or otherwise affect any obligation of the Trust, POT or the Administrator under Sections 10, 11 or 12.

If an Underwriter elects to terminate its obligations to purchase the Offered Securities as aforesaid, whether the reason for such termination is within or beyond the control of the Trust, POT or the Administrator, the liability of the Trust, POT or the Administrator hereunder shall be limited to the indemnity referred to in Section 10, the contribution rights referred to in Section 11 and the payment of the expenses referred to in Section 12.

The obligations of the Underwriters hereunder to purchase the Purchased Securities at the Closing Time shall be conditional upon: the Trust, POT and the Administrator having performed in all material respects, at the Closing Time, all of their obligations hereunder theretofore to be performed; there not having occurred any event or circumstance which, with the passage of time or notice or both, would entitle the Underwriters to terminate this agreement pursuant to Section 13(a); and the Underwriters receiving at the Closing Time:

All terms, covenants and conditions of this agreement to be performed by the Trust, POT and the Administrator shall be construed as conditions, and any breach or failure to comply with any material terms and conditions which are for the benefit of the Underwriters shall entitle the Underwriters to terminate their obligations to purchase the Purchased Securities, by written notice to that effect given to the Trust prior to the Closing Time.

All representations, warranties, terms and conditions herein (including, without limitation, those contained in Section 9) or contained in certificates or documents submitted pursuant to or in connection with the transactions contemplated herein shall survive the payment by the Underwriters for the Purchased Securities, the termination of this agreement and the distribution of the Purchased Securities pursuant to the Prospectus and shall continue in full force and effect for the benefit of the Underwriters for a period of three years from the Closing Date regardless of any investigation by or on behalf of the Underwriters with respect thereto.

The Underwriters' rights and obligations under this agreement are several and not joint and several including, without limitation, that:

each of the Underwriters shall be obligated to purchase only the percentage of the total number of Purchased Securities set forth opposite their names set forth in this Section 20; and

if one of the Underwriters does not purchase its applicable percentage of the total number of Purchased Securities, the other Underwriters who shall be willing and able to purchase their own applicable percentage of the total number of Purchased Securities shall be relieved of their obligations hereunder on submission to the Trust of reasonable evidence of their ability and willingness to fulfil their obligations hereunder at the Closing Time, provided that, notwithstanding the provisions of paragraph (b) of this Section 20, the Underwriters who shall be willing and able to purchase their applicable percentage of the total number of Purchased Securities shall have the right, but not the obligation, to purchase the total number of Purchased Securities.

In the event of a termination by the Trust, POT or the Administrator of their obligations under this agreement, there shall be no further liability on the part of the Trust, POT or the Administrator to the Underwriters except in respect of any liability which may have arisen or may thereafter arise under Sections 10, 11 or 12.

The Trust, POT and the Administrator shall be entitled to and shall act on any notice, waiver, extension or communication given by or on behalf of the Underwriters by BMO Nesbitt Burns Inc. and CIBC World Markets Inc., which shall represent the Underwriters and which shall have the authority to bind the Underwriters in respect of all matters hereunder, except in respect of any settlement under Section 10 or 11, any matter referred to in Section 13 or any agreement under Section 20.

For the purposes of this Section 22, the Underwriters shall be entitled to assume that the Offered Securities may be lawfully offered for sale and sold in the Qualifying Provinces by duly qualified investment dealers and brokers under Applicable Securities Laws in the Qualifying Provinces, if the final MRRS decision document has been issued evidencing that a receipt for the Prospectus has been issued by the Securities Commissions, provided the Underwriters do not have actual knowledge, and have not been notified in writing by the Trust or the Administrator, of any circumstances that would legally prohibit such distribution.

The Underwriters shall be entitled to offer the Offered Securities to certain purchasers in the United States in accordance with the terms set out in Schedule "A" attached hereto, which terms, and the representations, warranties and covenants set out in such Schedule shall be deemed to be incorporated by reference into this agreement.
