Each agreement of the Underwriters establishing a banking, selling or other group in respect of the distribution shall contain a similar covenant by each Selling Firm (as hereinafter defined). Any such reduction in the offering price shall not affect the Purchase Price to be paid to the Corporation.

Concurrently with the execution of this Agreement, the Corporation entered into a subscription agreement with an institutional investor providing for the sale by the Corporation to certain investment funds managed by the institutional investor of 20,470,000 Common Shares (the "Concurrent Offering Shares") at a price of C$17.10 per Common Share, for total gross proceeds of C$350,037,000 (the "Concurrent Offering").

- 29 -

(a) any order to cease or suspend trading in any securities of the Corporation or any of its subsidiaries, or prohibiting or restricting the distribution of the Purchased Securities, is made, or stop order preventing or suspending the use of any prospectus relating to the Purchased Securities has been issued, or proceedings are announced or commenced or, to the Corporation's knowledge, threatened for the making of any such order, by any Securities Commission, or by any other competent authority, unless such order has been rescinded, revoked or withdrawn or such proceedings have been discontinued or will not be proceeded with;

(b) any inquiry, investigation (whether formal or informal) or other proceeding in relation to the Corporation or any of its subsidiaries is announced or commenced or any order is issued by any Securities Commission or by any other competent authority, or there is any change of law or the interpretation or administration thereof by any such authority, if, in the opinion of the Underwriters (or any one of them) acting reasonably, the announcement, commencement or issuance thereof, or change, as the case may be, adversely affects the trading or distribution of the Purchased Securities;

(c) the Corporation shall be in breach of, default under or non-compliance with any material representation, warranty, covenant, term or condition of this Agreement;

The Underwriters shall notify the Corporation immediately of their knowledge of the existence of any of the circumstances set forth in this Section 12.1 (any such notice, a "Termination Condition Existence Notice").

- 30 -

Morgan Securities Canada Inc. and Wells Fargo Securities Canada, Ltd. (hereinafter referred to as the "Underwriters") and each of their respective directors, officers, employees, affiliates and agents and each person, if any, who controls any Underwriter within the meaning of section 15 of the 1933 Act, as amended, or section 20 of the 1934 Act and the successors and assigns of the foregoing persons (collectively, the "Indemnified Parties" or individually, the "Indemnified Party") from and against all liabilities, claims, losses (other than loss of profits), reasonable costs, damages and reasonable expenses (including, without limitation any legal fees or other expenses reasonably incurred by the Underwriters in connection with defending or investigating any such action or claim and securityholder or derivative actions, arbitration, proceedings or otherwise) (a "Claim") in any way caused by, or arising directly or indirectly from, or in consequence of:

(i) any information or statement (except any statement relating solely to such Underwriter or Underwriters which has been provided in writing to the Corporation by or on behalf of such Underwriter or Underwriters through the Lead Underwriters specifically for inclusion therein) contained in the Agreement, the Prospectuses, any Supplementary Material, including the documents incorporated by reference, the Issuer Free Writing Prospectus or any Prospectus Amendments (as such terms are defined in the Agreement) thereto, supplements or in any certificate of the Corporation delivered pursuant to the Agreement which, at the time and in the light of the circumstances under which it was made, contains or is alleged to contain a misrepresentation or untrue statement of a material fact;

(ii) any omission or alleged omission to state in the Prospectuses, any Supplementary Material, including the documents incorporated by reference, or any Prospectus Amendments thereto, supplements or in any certificate of the Corporation delivered pursuant to the Agreement, any material fact (except any fact relating solely to such Underwriter or Underwriters which has been provided in writing to the Corporation by or on behalf of such Underwriter or Underwriters through the Lead Underwriters specifically for inclusion therein) regarding the Corporation and its operations and affairs that is necessary to make any statement therein not misleading in light of the circumstances in which it was made;

A-2

(iii) any order made or enquiry, investigation or proceedings commenced or threatened by any securities commission or other competent authority based upon any untrue statement or omission or alleged untrue statement or alleged omission or any misrepresentation or alleged misrepresentation (except a statement or omission or alleged statement or omission regarding facts relating solely to any such Underwriter or Underwriters through the Lead Underwriters which has been provided in writing to the Corporation specifically for inclusion therein) in the Prospectuses, any Supplementary Material including any documents incorporated by reference, the Issuer Free Writing Prospectus or any Prospectus Amendments or supplements thereto or based upon any failure to comply with the Applicable Securities Laws (as such term is defined in the Agreement) (other than any failure or alleged failure to comply by any such Underwriter or Underwriters), preventing or restricting the trading in or the sale or distribution of the Purchased Securities;

(iv) the non-compliance or alleged noncompliance by the Corporation with any of the Applicable Securities Laws, including, in the case of the Corporation, the Corporation's non-compliance with any statutory requirement to make any document available for inspection; or

(v) any breach by the Corporation of its material representations, warranties, covenants or obligations to be complied with under the Agreement.

This indemnity shall cease to be available to an Indemnified Party if: (i) a court of competent jurisdiction in a final judgment in which such Indemnified Party is named as a party determines that the Claim in respect of which indemnification is sought is a result of or arises out of the gross negligence or willful misconduct of such Underwriter or Underwriters (provided that, for greater certainty, the Corporation and any such Underwriter or Underwriters agree that they do not intend that any failure by such Underwriter or Underwriters to conduct such reasonable investigation as necessary to provide any Underwriters or Underwriters with reasonable grounds for believing the Prospectuses, any Supplementary Material, including any documents incorporated by reference, the Issuer Free Writing Prospectus or any Prospectus Amendments or supplements thereto, contained no misrepresentation shall constitute "gross negligence" or "willful misconduct" for purposes of this Section 1 or otherwise disentitle the Underwriters from indemnification hereunder); or (ii) a copy of the Prospectuses (as then amended or supplemented, if the Corporation shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of the Underwriters to a person asserting any such losses, claims, damages or liabilities, but only (x) if required by law so to have been delivered by the Underwriters to such person, at or prior to the written confirmation of the sale of the Purchased Securities to such person, and (y) if the Prospectuses (as so amended or supplemented) delivered by the Underwriters a reasonable amount of time in advance of such confirmation would have cured the defect giving rise to such losses, claims, damages or liabilities. In such event, such Underwriter or Underwriters shall reimburse any funds advanced by the Corporation to such Underwriter or Underwriters pursuant to the indemnification contained in this Schedule A in respect of such Claim and thereafter this indemnity shall cease to apply to such Underwriter or Underwriters in respect of such Claim.

A-3

(b) Notification of Claims

If any Claim is asserted against any Indemnified Party, such Indemnified Party will notify the Corporation as soon as possible of the nature of such Claim (but the omission so to notify the Corporation of any potential Claim shall not relieve the Corporation from any liability which it may have to any Indemnified Party and any omission so to notify the Corporation of any actual Claim shall affect the Corporation's liability only to the extent that it is prejudiced as a proximate result of that failure). Subject to subsection 1(d), the Corporation shall be entitled to participate in and, to the extent that it shall wish, to assume the defense of any suit brought to enforce such Claim; provided, however, that the defense shall be conducted through legal counsel acceptable to such Indemnified Party, acting reasonably, that no settlement of any such Claim or admission of liability may be made by the Corporation or such Indemnified Party without the prior written consent of the other parties, acting reasonably, and the Corporation shall not be liable for any settlement of any such Claim unless it has consented in writing to such settlement. The Corporation shall not settle any Claim, or compromise a consent to any judgment unless such settlement, compromise or judgment (i) includes an unconditional release of such Indemnified Party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of such Indemnified Party.

(c) Right of Indemnity in Favour of Others

With respect to any Indemnified Party who is not a party to the Agreement, the Indemnified Parties who are party to the Agreement shall obtain and hold the rights and benefits of this Section in trust for and on behalf of such Indemnified Party.

(d) Retaining Counsel

In any Claim, the Indemnified Party shall have the right to retain other counsel to act on its behalf, provided that the reasonable fees and disbursements of such counsel shall be paid by such Indemnified Party unless (i) the Corporation fails to assume the defense of such suit on behalf of such Indemnified Party within 10 days of receiving written notice of such suit; (ii) the Corporation and such Indemnified Party shall have mutually agreed to the retention of the other counsel; or (iii) the named parties to any such Claim (including any added third or impleaded party) include such Indemnified Party and the Corporation and such Indemnified Party shall have been advised by counsel that the representation of all parties by the same counsel would be inappropriate due to the actual or potential differing interests between them, including the potential availability of one or more legal defenses to such Indemnified Party which are different from or in addition to those available to the other parties or the potential for a conflict to exist between the Corporation and such Indemnified Party. In no event shall the Corporation be liable to pay the fees and disbursements of more than one firm of separate counsel for all Indemnified Parties and, in addition, one firm of local counsel in each applicable jurisdiction.

2. Contribution

(a) Contribution by the Corporation

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 1 of this Schedule A is unavailable, in whole or in part, for any reason to an Indemnified Party in respect of any Claim, the Corporation (the "Indemnifier") and the applicable Underwriter or Underwriters shall contribute to the amount paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by the Corporation as a result of such Claim in such proportion as is appropriate to reflect the relative benefits received by the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand from the offering of the Purchased Securities; or if this allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand in connection with the information, statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule A which resulted in such Claim, as well as any other relevant equitable considerations.

A-4

The relative benefits received by the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand shall be deemed to be in the same proportion as the total proceeds (net of the fee payable to the applicable Underwriter or Underwriters but before deducting any expenses (to the extent that such expenses are payable by the Corporation pursuant to Section 3 of this Schedule A)) received by the Corporation from the issue and sale of the Purchased Securities bears to the fee received by the applicable Underwriter or Underwriters, in each case, as set out in the table on the face page of the Prospectuses. The relative fault of the Corporation on the one hand and of the applicable Underwriter or Underwriters on the other shall be determined by reference to, among other things, whether the information, statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule A which resulted in such Claim relates to information supplied by or steps or actions taken or done by or on behalf of the Corporation or to information supplied by or steps or actions taken or done by or on behalf of the applicable Underwriter or Underwriters and the relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule A. The amount paid or payable by an Indemnified Party as a result of the Claim referred to above shall include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such Claim, whether or not resulting in any such action, suit, proceeding or claim. The Corporation and the applicable Underwriter or Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 2 were determined by any method of allocation which does not take into account the equitable considerations referred to immediately above.

A person who is engaged in any fraud, fraudulent misrepresentation or gross negligence shall not, to the extent that a court of competent jurisdiction in a final judgment determines that the Claim was caused by that activity, be entitled to claim contribution therefor from any person who has not also been determined by a court of competent jurisdiction in a final judgment to have engaged in that fraud, fraudulent misrepresentation or gross negligence.

(b) Right of Contribution in Addition to Other Rights

The rights to contribution provided in this Section 2 shall be in addition to and not in derogation of any other right to contribution which the applicable Underwriter or Underwriters may have by statute or otherwise at law.

(c) Calculation of Contribution

In the event that a court of competent jurisdiction in a final judgment determines that an Indemnifier is entitled to contribution from the applicable Underwriter or Underwriters under the provisions of any statute or at law, the Indemnifier shall be limited to contribution in an amount not exceeding the lesser of:

A-5

(i) the portion of the full amount of the loss or liability giving rise to such contribution for which the applicable Underwriter or Underwriters are responsible, as determined in subsection 2(a) of this Schedule A, and

(ii) the amount of the fee actually received by the applicable Underwriter or Underwriters from the Corporation under the Agreement, provided that no Underwriter shall be required to contribute any amount in excess of the fee received by such Underwriter in connection with the Purchased Securities sold by it.

(d) Notice of Claim for Contribution

Notification to the Corporation of a Claim pursuant to subsection 1(b) of this Schedule A shall be deemed to also constitute notice to the Corporation that a claim for contribution by the applicable Underwriter or Underwriters may arise and omission to so notify shall have similar effect.

(e) Right of Contribution in Favour of Others

The Corporation hereby acknowledges and agrees that, with respect to paragraphs 1 and 2 of this Schedule A, each of the Underwriters are contracting on their own behalf and as agents for their affiliates, subsidiaries, directors, officers, employees, agents and control persons (collectively, the "Beneficiaries"). In this regard the applicable Underwriter or Underwriters shall act as trustees for the Beneficiaries of the Corporation's covenants under paragraphs 1 and 2 of this Schedule A with respect to the Beneficiaries and accept these trusts and shall hold and enforce the covenants on behalf of the Beneficiaries.

3. Severability

If any provision of Section 1 or 2 of this Schedule A is determined to be void or unenforceable in whole or in part, it shall be deemed not to affect or impair the validity of any other provision of the Agreement and such void or unenforceable provision shall be severable from the Agreement.
