(a) any information or statement (except any information or statement relating solely to the Underwriters, or any of them, provided by the Underwriters to the Company in writing expressly for inclusion in the Offering Documents) contained in any of the Offering Documents being or being alleged to be a misrepresentation or untrue or any omission or

(c) any breach by the Company of, or default under, any covenant or agreement of the Company in this Agreement which has not been waived by the Underwriters under this Agreement or any inaccuracy of any representation or warranty in this Agreement or any other document to be delivered pursuant hereto or the failure of the Company to comply with any of its obligations hereunder or thereunder;

(d) the Company not complying prior to the completion of the distribution of the Purchased Shares or the Additional Common Shares with any requirement of any Applicable Securities Laws relating to the Offering;

(e) any order made or any inquiry, investigation or proceeding instituted, threatened or announced by any court, securities regulatory authority or stock exchange (including the Exchanges) or by any other competent authority, based upon any untrue statement, omission or misrepresentation or alleged untrue statement, omission or misrepresentation (except a statement, omission or misrepresentation relating to the Underwriters, or any of them, provided by the Underwriters to the Company in writing expressly for inclusion in the Offering Documents) contained in the Offering Documents which operates to prevent or restrict the trading in or the sale or distribution of the Purchased Shares or the Additional Common Shares;

and shall reimburse the Indemnified Parties for all reasonable costs, charges and expenses, as incurred, which any of them may pay or incur in connection with investigating or disputing any Claim or action related thereto including the fees and expenses of legal counsel on a solicitor and own client basis and including reimbursement paid to the Underwriters for the time spent by the Indemnified Parties in connection with any Claim payable at the normal per diem rates of such Indemnified Parties.

This indemnity shall be in addition to any liability that the Company may otherwise have.

12.2 If any Claim contemplated by this section 12 is asserted against any of the Indemnified Parties, or if any potential Claim contemplated by this section 12 comes to the knowledge of any of the Indemnified Parties, the Indemnified Party concerned shall notify in writing the Company as soon as reasonably practicable, of the nature of the Claim (provided that any failure to so notify in respect of any potential Claim shall not affect the liability of the Company under this section 12, except to the extent that such delay prejudices the Company’s ability to contest such Claim). The Company shall, subject to the following, be entitled (but not required) to assume the defence on behalf of the Indemnified Party of any suit brought to enforce the Claim; provided that the defence shall be through legal counsel selected by the Company and acceptable to the Indemnified Party, acting reasonably, and no admission of liability or settlement of the Claim shall be made by the Company without the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld. An Indemnified Party shall have

the right to employ separate counsel in any such suit and participate in its defence but the fees and expenses of that counsel shall be at the expense of the Indemnified Parties unless:

(a) the Company fails to assume the defence of the suit on behalf of the Indemnified Party within ten days of receiving notice of the suit;

(b) the employment of that counsel has been authorized in writing by the Company; or

(c) the named parties to the suit (including any added or third parties) including the Company and the Indemnified Party have been advised in writing by outside counsel that representation of the Indemnified Party by counsel for the Company is inappropriate as a result of the potential or actual conflicting interests of those represented.

In each of the cases set out in subsections 12.2(a), (b) or (c), the Company shall not have the right to assume the defence of the suit on behalf of the Indemnified Party, but the Company shall be liable to pay the reasonable fees and expenses of separate counsel for all Indemnified Parties and, in addition, of local counsel in each applicable jurisdiction on a solicitor and own client basis. Notwithstanding the foregoing, no settlement may be made by an Indemnified Party without the prior written consent of the Company, which consent shall not be unreasonably withheld.

12.3 The Company hereby acknowledges and agrees that, with respect to this section 12, the Underwriters are contracting on their own behalf and as agents for their affiliates, directors, officers, employees and agents and their respective affiliates, directors, officers, employees, partners, shareholders, advisers and agents (collectively, the “Beneficiaries”). In this regard, each of the Underwriters shall act as trustee for the Beneficiaries of the covenants of the Company under this section 12 with respect to the Beneficiaries and accepts these trusts and will hold and enforce those covenants on behalf of the Beneficiaries.

12.4 In order to provide for just and equitable contribution in circumstances in which the indemnity provided in this section 12 would otherwise be available in accordance with its terms but is, for any reason not attributable to any one or more of the Indemnified Parties, held to be unavailable to or unenforceable by an Indemnified Party or is insufficient to hold the Indemnified Party harmless, the Company shall contribute to the amount paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by such Indemnified Party as a result of such liabilities, claims, demands, losses, costs, damages and expenses:

(a) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Purchased Shares and the Additional Common Shares, if any; or

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

provided that the Underwriters shall not in any event be liable to contribute, in the aggregate, any amount in excess of the Underwriting Fee or any portion thereof actually received.

The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same ratio as the total proceeds from the offering of the Purchased Shares and the Additional Common Shares, if any, (net of the Underwriting Fee payable to the Underwriters but before deducting expenses) received by the Company is to the Underwriting Fee received by the Underwriters.

The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the matters or things referred to in this section 12 which resulted in such liabilities, claims, demands, losses, costs, damages and expenses relate to information supplied by or steps or actions taken or done or not taken or done by or on behalf of the Company or to information supplied by or steps or actions taken or done or not taken or done by or on behalf of the Underwriters and the relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission or misrepresentation, or other matter or thing referred to this section 12. The amount paid or payable by an Indemnified Party as a result of the liabilities, claims, demands, losses, costs, damages and expenses referred to above shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such liabilities, claims, demands, losses, costs, damages and expenses, whether or not resulting in an action, suit, proceeding or claim.

The parties agree that it would not be just and equitable if contribution pursuant to this section were determined by any method of allocation which does not take into account the equitable considerations referred to in this section.

13. TERMINATION OF AGREEMENT

13.1 Except as otherwise provided herein, all terms and conditions set out herein shall be construed as conditions and any breach or failure by the Company to comply with any conditions in favour of the Underwriters shall entitle any Underwriter to terminate in accordance with section 13.2(d) its obligation to purchase the Purchased Shares and any Additional Common Shares by written notice to that effect given to the Company prior to the Closing Time on the Closing Date or Option Closing (as applicable). The Company shall use its best efforts to cause all conditions in this Agreement to be satisfied.
