(i): any information or statement contained in the Preliminary Prospectus, the Prospectus, any Supplementary Material or in any other document or material filed or delivered pursuant hereto (other than any information or statement relating solely to the Underwriters and furnished to the Trust by the Underwriters expressly for inclusion in the Preliminary Prospectus or Prospectus) which is or is alleged to be untrue or any

omission or alleged omission to provide any information or state any fact (other than any information or fact relating solely to the Underwriters) the omission of which makes or is alleged to make any such information or statement untrue or misleading in light of the circumstances in which it was made;

(ii): any misrepresentation or alleged misrepresentation (except a misrepresentation which is based upon information relating solely to the Underwriters and furnished to the Trust by the Underwriters expressly for inclusion in the Preliminary Prospectus or Prospectus) contained in the Preliminary Prospectus, the Prospectus, any Supplementary Materials or in any other document or any other part of the Public Record filed by or on behalf of the Trust;
(iii): any prohibition or restriction of trading in the securities of the Trust or any prohibition or restriction affecting the distribution of Subscription Receipts or the the Trust Units issuable pursuant to the Subscription Receipts imposed by any competent authority if such prohibition or restriction is based on any misrepresentation or alleged misrepresentation of a kind referred to in subparagraph 8(a)(ii);
(iv): any order made or any inquiry, investigation (whether formal or informal) or other proceeding commenced or threatened by any one or more competent authorities (not based upon the activities or the alleged activities of the Underwriters or their banking or Selling Dealer Group members, if any) prohibiting, restricting, relating to or materially affecting the trading or distribution of the Subscription Receipts or the Trust Units issuable pursuant to the Subscription Receipts; or
(v): any breach of, default under or non-compliance by the Trust or PC with any requirements of the Applicable Securities Laws, the by-laws, rules or regulations of the Exchanges or any representation, warranty, term or condition of this agreement or in any certificate or other document delivered by or on behalf of the Trust or PC hereunder or pursuant hereto;

provided, however, no party who has engaged in any fraud, wilful misconduct, fraudulent misrepresentation or negligence shall be entitled, to the extent that the liabilities, claims, losses, costs, damages or expenses were caused by such activity, to claim indemnification from any person who has not engaged in such fraud, wilful misconduct, fraudulent misrepresentation or negligence (provided that for greater certainty, the foregoing shall not disentitle an Underwriter from claiming indemnification hereunder to the extent that the negligence, if any, relates to the Underwriter's failure to conduct adequate "due diligence").

(b)

If any claim contemplated by paragraph 8(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 and PC (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 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 paragraph 8(a) if:

(i): 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);
(ii): 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
(iii): 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.

(c): 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 or the Prospectus.
(d): 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 the Subscription Receipts or the Trust Units issuable pursuant to the Subscription Receipts 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 or the Subscription Receipts or the Trust Units issuable pursuant to the Subscription Receipts 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.
(e): The rights and remedies of the Indemnified Persons set forth in paragraphs 8, 9 and 10 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.
(f): The Indemnifying Parties hereby acknowledge that the Underwriters are acting as agents for the Underwriters' respective agents, directors, officers, shareholders and employees under this paragraph 8 and under paragraph 9 with respect to all such agents, directors, officers, shareholders and employees.
(g): 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.

(h): The rights of indemnity contained in this paragraph 8 shall not apply if the Indemnifying Parties have complied with the provisions of paragraphs 3, 4 and 5 and the person asserting any claim contemplated by this paragraph 8 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.
(i): 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.

9. Contribution

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 Subscription Receipts), costs (including, without limitation, 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:

(a): 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 Subscription Receipts; or
(b): if the allocation provided by paragraph 9(a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in paragraph 9(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 paragraph 8 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 paragraph 8.

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 Subscription Receipts), 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 paragraph 9 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 paragraph 9 shall be limited to the amount actually received by the Underwriters under paragraph 2.

10. Expenses

(a): Whether or not the transactions contemplated herein shall be completed, subject to paragraph 10(c), 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 Subscription Receipts 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, any Supplementary Material 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 expenses related to audio-visual and teleconference presentations, including the costs associated with audio-visual personnel, hotel, food and travel expenses incurred in connection with marketing meetings, and reasonable hotel and travel expenses for the Underwriters incurred in connection with the marketing meetings, the fees and expenses related to any newspaper

(b): If the public offering of the Subscription Receipts is not completed due to any reason whatsoever, 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 reasonable 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 (collectively, the "Underwriters' Expenses"); provided, however, that if the purchase and sale of the Trust Units is not completed in accordance with the terms hereof by reason of a breach by or default of the Underwriters, the Underwriters shall be responsible for all such fees, disbursements and expenses;
(c): If the public offering of the Subscription Receipts is completed, the Underwriters shall be responsible for the Underwriters' Expenses; and
(d): 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 such expenses of the Underwriter's Expenses to the Trust as soon as practicable following the termination of the public offering and the Trust shall reimburse the Underwriters within 30 days of receipt of reasonable evidence of the Underwriters' Expenses.

(viii): the Termination Time has occurred.

(b): The Underwriters, or any of them, may exercise any or all of the rights provided for in paragraph 11(a) or paragraph 12 or 16 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 Subscription Receipts 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 paragraph 11(a) or paragraph 12 or 16 if such waiver or estoppel is in writing and specifically waives or estops such exercise or reliance;

All representations, warranties, terms and conditions herein (including, without limitation, those contained in paragraph 7) 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 Subscription Receipts, the termination of this agreement and the distribution of the Subscription Receipts pursuant to the Prospectus and shall continue in full force and effect for the benefit of the Underwriters regardless of any investigation by or on behalf of the Underwriters with respect thereto.

18. Several Liability of Underwriters

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

(a): each of the Underwriters shall be obligated to purchase only the percentage of the total number of Subscription Receipts (which for greater certainty for the purposes of this paragraph 18 shall include the Optioned Receipts in respect of which the Underwriters' Option is exercised) set forth opposite their names set forth in this paragraph 18; and
(b): if at the Closing Time any one or more of the Underwriters shall fail or refuse to purchase its respective percentage set forth below of the aggregate number of the Subscription Receipts (other than in accordance with section 11) and the number of such Subscription Receipts which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than 7% of the aggregate number of Subscription Receipts to be purchased on such date, the non-defaulting Underwriters shall be obligated severally, in the proportions that the respective percentage set forth below opposite the names of all such non-defaulting Underwriters, to purchase the Subscription Receipts which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase at such time; and
(c): if any one or more of the Underwriters shall not purchase its applicable percentage of the Subscription Receipts at the Closing Time and the number of such securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is more than 7% of the aggregate number of Subscription Receipts to be purchased at such time, then the other Underwriters shall have the right, but shall not be obligated, to purchase all of the percentage of the Subscription Receipts which would otherwise have been purchased by such one or more of the Underwriters; the Underwriters exercising such right shall

purchase such Subscription Receipts pro rata to their respective percentages aforesaid or in such other proportions as they may otherwise agree. In the event such right is not exercised, the Underwriters which are not in default shall be entitled by written notice to the Trust to terminate this agreement without liability.

In the event of a termination by the Trust or PC of their obligations under this agreement there shall be no further liability on the part of the Trust or PC to the Underwriters except in respect of any liability which may have arisen or may thereafter arise under paragraphs 8, 9 and 10.

(c): use all reasonable efforts to complete the distribution of Subscription Receipts as soon as possible;
(d): not solicit subscriptions for the Subscription Receipts, trade in Subscription Receipts or otherwise do any act in furtherance of a trade of Subscription Receipts in any jurisdictions outside of the Qualifying Provinces, provided further, that neither it, nor its affiliates nor any person acting on its behalf, shall make any offers or sales of the Subscription Receipts (or the Trust Units issuable pursuant to the Subscription Receipts) within the United States, or to, or for the benefit or account of, U.S. persons; and it, its affiliates and any person acting on its behalf shall conduct all offers and sales in accordance with Regulation S under the United States Securities Act of 1933, as amended; and

No Underwriter will be liable to the Trust under this paragraph 20 with respect to a default by any of the other Underwriters but will be liable to the Trust only for its own default.

21. Severance

If one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this agreement, but this agreement shall be construed as if such invalid, illegal or unenforceable provision or provisions had never been contained herein.

22. Relationship Between the Trust, PC and the Underwriters

The Trust and PC: (i) acknowledge and agree that the Underwriters have certain statutory obligations as registrants under the Applicable Securities Laws and have fiduciary relationships with their clients; (ii) acknowledge and agree that the Underwriters are neither the agents of the Trust or PC nor otherwise fiduciaries of the Trust or PC; and (iii) consent to the Underwriters acting hereunder while continuing to act for their clients. To the extent that the Underwriters' statutory obligations as registrants under the Applicable Securities Laws or fiduciary relationships with their clients conflicts with their obligations hereunder the Underwriters shall be entitled to fulfil their statutory obligations as registrants under the Applicable Securities Laws and their duties to their clients. Nothing in this agreement shall be interpreted to prevent the

Underwriters from fulfilling their statutory obligations as registrants under the Applicable Securities Laws or to act as a fiduciary of their clients.

23. Stabilization

In connection with the distribution of the Subscription Receipts, the Underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Subscription Receipts and Trust Units at levels other than those which might otherwise prevail in the open market, but in each case only as permitted by applicable law. Such stabilizing transactions, if any, may be discontinued at any time.
