(b) Notification of Claims. If any matter or thing contemplated by this paragraph (any such matter or thing being referred to as a "Claim") is asserted against any person or Corporation in respect of which indemnification is or might reasonably be considered to be provided, such person or Corporation (the "Indemnified Party") will notify the Corporation or the Corporation, as the case may be (as applicable, the "Indemnifying Party") as soon as possible of the nature of such Claim and the Indemnifying Party 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 conducted through legal counsel acceptable to the Indemnified Party, acting reasonably, and that no settlement of any such Claim may be made by the Indemnifying Party or the Indemnified Party without the prior written consent of the other parties, such consent not to be unreasonably withheld. (c) Right of Indemnity in Favour of Others. With respect to any Indemnified Party who is not a party to this Agreement, the Underwriter or the Corporation, as applicable, shall obtain and hold the rights and benefits of this paragraph and paragraph 14 in trust for and on behalf of such Indemnified Party. (d) Retaining Counsel. In any such Claim, the Indemnified Party shall have the right to retain other counsel to act on his, her or its behalf and to participate in the defence thereof, provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless: (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of the other counsel, (ii) the Indemnifying Party fails to assume the defence of such Claim on behalf of the Indemnified Party within ten days of receiving notice of such Claim, or (iii) the named parties to any such Claim (including any added third or impleaded party) include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have been advised by counsel that representation of the Indemnified Party by counsel for the Indemnifying Party is inappropriate as a result of potential or actual differing interests of those represented; in each of which cases such Indemnifier shall not have the right to assume the defence of such Claim on behalf of the Indemnified Party but the Indemnifying Party shall be liable to pay the reasonable fees and disbursements of counsel to the Indemnified Party; provided that the Indemnifying Party shall not be obligated to pay fees and expenses of more than one separate legal firm for all Indemnified Parties, as a group. 14. (a) Contribution. In order to provide for a just and equitable contribution in circumstances in which the indemnity provided in paragraph 13 would otherwise be available in accordance with its terms but is, for any reason, held to be unavailable to or unenforceable by the Underwriter or enforceable otherwise than in accordance with its terms, the Corporation, the Corporation and the Underwriter shall severally contribute to the aggregate of all claims, expenses, costs and liabilities and all losses (other than loss of profits) of a nature contemplated in paragraph 13 in such proportions so that the Underwriter is responsible for the portion represented by the percentage that the aggregate fee payable by the Corporation to the Underwriter bears to the aggregate offering price of the Units and the Indemnifying Party is responsible for the balance. The Underwriter shall not in any event be liable to contribute, in the aggregate, any amounts in excess of such aggregate fee or any portion of such fee actually received. However, no party who has engaged in any fraud, fraudulent misrepresentation or gross negligence shall be entitled to claim contribution from any person who has not engaged in such fraud, fraudulent misrepresentation or gross negligence. (b) Right of Contribution in Addition to Other Rights. The rights to contribution provided in this paragraph shall be in addition to and not in derogation of any other right to contribution which the Underwriter may have by statute or otherwise at law. (c) Calculation of Contribution. In the event that an Indemnifying Party may be held to be entitled to contribution from the Underwriter under the provisions of any statute or at law, the Indemnifying Party shall be limited to contribution in an amount not exceeding the lesser of: (i) the portion of the full amount of the loss or liability giving rise to such contribution for which the Underwriter is responsible, as determined in subparagraph 14(a) above; and (ii) the amount of the aggregate fee actually received by the Underwriter from the Corporation under this Agreement. (d) Notice. If the Underwriter has reason to believe that a claim for contribution may arise, they shall give the Indemnifying Party notice of such claim in writing, as soon as reasonably possible, but failure to notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation which it may have to the Underwriter under this paragraph. 15. Right of First Refusal. Subject to completion of the Offering, the Underwriter is hereby granted the right of first refusal to act as lead underwriter of any further offering of securities of the Corporation in Canada and, to the extent qualified in the United States, to participate as a managing underwriter in an amount equal to not less than 20%, in any offering of securities by the Corporation, either wholly or partially in the United States, including a follow-on issue of Common Shares, in each case, for a period of eighteen months from the Closing Date. 16.
