Subject to Section 2.1(b) and 2.1(c), during the Registration Period, to the extent permitted under Securities Laws, the Issuer shall use commercially reasonable efforts to maintain a Base Prospectus filed with the Canadian Securities Commissions and maintain the effectiveness of a Registration Statement filed with the SEC that qualifies the distribution of Registrable Securities by Holders in any or all of the provinces of Canada (in the case of the Base Prospectus) and in the United States (in the case of the Registration Statement) under applicable

Within 15 days of the date on which a Suspension Registration Period begins, the Issuer shall use commercially reasonable efforts to file a Base Prospectus and a Registration Statement. Following such filing, the Issuer shall use commercially reasonable efforts to have such Base Prospectus and Registration Statement, as applicable, become valid and effective. For certainty, provided that the Issuer is in compliance with this Section 2.2(b), the Issuer shall not be considered to be in default of Section 2.1(a) and the Base Prospectus and Registration Statement shall not be considered to be not valid and effective under Section 2.1(d).

Each Holder who is a party to this Agreement (including any assignee under Section 2.6) shall promptly provide all such information as the Issuer reasonably requires to include such Holder as a selling securityholder under the Base Prospectus and Registration Statement maintained by the Issuer pursuant to Section 2.1(a). Within 10 days of the Issuer receiving all such information as the Issuer requires to include a Holder as a selling securityholder under the Base Prospectus and Registration Statement maintained by the Issuer pursuant to 2.1(a), the Issuer shall use commercially reasonable efforts to file an amendment to the Base Prospectus and Registration Statement to include such Holder as a selling securityholder and following such filing, the Issuer shall use commercially reasonable efforts to have such amended Base Prospectus and Registration Statement, as applicable, become valid and effective; provided that the Issuer shall not be obligated to file an amendment to the Base Prospectus or Registration Statement pursuant to this Section 2.1(c) more than three times during any 12-month period. No Holder shall be entitled to be included as a selling securityholder under the Base Prospectus or Registration Statement (and the Issuer shall not be considered to be in default of Section 2.1(a) or Section 2.1(b) and the Base Prospectus and Registration Statement shall not be considered to be not valid and effective under Section 2.1(d)) until such time as the Issuer has received from the Holder all such information as the Issuer reasonably requires to include such Holder as a selling securityholder under the Base Prospectus or Registration Statement and the above 10-day period has expired.

Subject to Section 2.1(b) and 2.1(c), if a Base Prospectus or a Registration Statement that satisfies the requirement in Section 2.1(a) is not valid or effective, as the case may be, at any time during the Registration Period, in either case, for a period of 45 consecutive days, then, from but not including that 45^th day until the day on which there is a Base Prospectus or Registration Statement, as applicable, that is valid or effective, as applicable, satisfying the requirement in Section 2.1(a), the rights and obligations contained herein shall apply to a Non-Base Prospectus and all references in this Agreement to Prospectus Supplement shall apply mutatis mutandis to a Non-Base Prospectus; provided, however, that the Issuer shall in any event be entitled to satisfy its obligations hereunder with a Base Prospectus or Registration Statement.

Required Registration

Subject to the limitations and other provisions hereof and Securities Laws, at any time and from time to time during the Registration Period, one or more Holders may request (each, a “Demand Offering Request”) the Issuer to file a Prospectus Supplement with the Canadian Securities Commissions and/or the SEC pursuant to an effective Registration Statement for the offering of all or (subject to Section 2.2(c)) any part of the Registrable Securities (such offering being hereinafter referred to as a “Demand Offering” and any Registration of such Demand Offering being hereinafter referred to as a “Demand Registration”). Each Demand Offering Request shall be in writing and shall specify the number of Registrable Securities to be sold by the Holders (the “Demand Registrable Securities”), the method of disposition of such Demand Registrable Securities and the jurisdictions (which may only include one or more of the provinces of Canada and/or the United States) in which the Holders request that the Demand Offering be effected for such Demand Registrable Securities. The Prospectus Supplement for any such Demand Offering shall be filed promptly with, in the case of a Canadian Offering, the applicable Canadian Securities Commissions or, in the case of a U.S. Offering, the SEC, as applicable, after a Demand Offering Request is received by the Issuer; provided, however, if the Demand Offering Request is only in respect of a U.S. Offering, the Issuer shall also file such Prospectus Supplement (or a corresponding Canadian version of such Prospectus Supplement, as applicable) in any applicable province of Canada if and solely to the extent required for the purposes of such U.S. Offering under the requirements of MJDS or applicable Canadian Securities Laws. The Issuer shall not be obligated to effect more than three Demand Offerings in total during the Registration Period. For the purposes of this subsection 2.2(a), a Demand Offering will not be considered as having been effected until (i) a Prospectus Supplement pursuant to which the Demand Registrable Securities are to be sold has been filed with the applicable Canadian Securities Commissions and/or the SEC, as applicable, (ii) the Holders have withdrawn its request for the Demand Offering in writing or (iii) the applicable Holders have failed to fulfill their respective obligations under this Agreement with respect to such Demand Offering. In the event that the Issuer proposes to offer and sell its securities as part of any Demand Offering requested by the Holders under this Agreement, and if the managing underwriter or underwriters (selected as provided for in Section 2.3) advise the Issuer in good faith that the inclusion of the securities requested by the Issuer to be included in such offering will likely, in their opinion, have an adverse effect on the distribution or sales price of the Demand Registrable Securities in such offering, then the number of securities to be offered by the Issuer for its own account in such offering shall be reduced as necessary to avoid such adverse effect.

The Issuer shall be entitled to postpone the filing of a Prospectus Supplement otherwise required to be prepared and filed by it pursuant hereto (or withdraw any Prospectus Supplement that has been filed by it pursuant hereto) if, at the time it receives a Demand Offering Request or before a Demand Offering has been completed, the Chief Executive Officer or Chief Financial Officer of the Issuer, in his or her good faith judgment, determines that the Demand Offering should not be initiated or completed because (i) it would materially interfere with any material financing, acquisition, corporate reorganization or merger or other

The Issuer shall not be required to effect a Demand Offering in connection with an underwritten offering of Registrable Securities unless the Demand Registrable Securities have an aggregate market price of at least $50 million. Market price for the purposes of the foregoing shall be calculated on the basis of the average of the volume weighted average trading prices of the Common Shares on the TSX on each of the 15 trading days immediately preceding the delivery by the Holders to the Issuer of the request for the Demand Offering.

Subject to Section 2.2(e), if during the Registration Period the Issuer proposes to file a Prospectus Supplement in Canada and/or the United States in order to offer its Common Shares pursuant to an underwritten offering (excluding, for greater certainty, any offering in connection with a merger, acquisition or other business combination or an offering solely to then existing securityholders of the Issuer) for its own account (a “Treasury Offering”), in a form and manner that, with appropriate changes to the documentation to reflect the addition of a secondary offering, would permit the offering of Registrable Securities under such Prospectus Supplement, the Issuer shall give notice in accordance with Section 6.2 of its intention to do so to the Holders not less than 5 Business Days in advance of the anticipated filing date of the Prospectus Supplement and, within 3 Business Days of the Issuer sending such notice to the Holders (or such shorter period as is provided therefor in Section 2.2(e), the “Piggy Back Notice Period”), the Holders have the right to request in writing to the Issuer (such request hereinafter referred to as “Piggy Back Offering Request”) to include (and upon such request being received by the Issuer within the Piggy Back Notice Period, the Issuer shall use commercially reasonable efforts to include) in the Treasury Offering such number of Registrable Securities (the “Piggy Back Registrable Securities”, and together with the Demand Registrable Securities, the “Designated Registrable Securities”) as the Holders shall request (any Registration of Piggy Back Registrable Securities to be offered pursuant to such request hereinafter referred to as a “Piggy Back Registration”, and together with a Demand Registration, a “Secondary Registration”) upon the same terms (including the method of distribution) as such Treasury Offering; provided that (i) the Issuer shall not be required to include all such Piggy Back Registrable Securities in any such Treasury Offering if the Issuer is advised in good faith by its managing underwriter or underwriters that the inclusion of any such Piggy Back Registrable Securities will likely, in their opinion, have an adverse effect on the distribution or sales price of the securities being offered by the Issuer, in which case the number of Piggy Back Registrable Securities shall be reduced as

Notwithstanding the foregoing, in the event that the Issuer proposes to effect a Treasury Offering by way of a “bought deal”, or another public offering which is not expected to include a road show, (i) the notice periods set forth in Section 2.2(d) shall not be applicable, (ii) the Issuer shall give the Holders such notice of the Treasury Offering as is practicable under the circumstances (given the speed and urgency with which bought deals or such other public offerings are then carried out in common market practice) of its rights to participate thereunder and (iii) in lieu of the 5-Business Day Piggy Back Notice Period provided for in in Section 2.2(d), the Holders shall instead have only such time to make a Piggy Back Offering Request as is practicable under the circumstances, and sufficiently in advance of the execution of the bought deal letter (in the case of a “bought deal” offering) or announcement of such public offering, as applicable, to notify the Issuer that one or more Holders wish to participate in such Treasury Offering, failing which, the Issuer shall be free to pursue the bought deal or such other public offering without the participation of the Holders.

For greater certainty, notwithstanding any participation by the Holders in a Treasury Offering pursuant to subsection 2.2(d), the terms and manner of sale for any Treasury Offering, including the jurisdictions in which it is effected, shall be within the sole discretion of the Issuer.

For clarity, a Holder may not assign any of its rights under this Agreement to a Person other than an Affiliate of Brookfield and in the case of an assignment of the rights hereunder in respect of less than all of such Holder’s Registrable Securities, no such assignment will limit or otherwise impair the assignor’s rights or obligations under this Agreement. The Holder shall provide the Issuer with written notice prior to such assignment (and such assignment shall not be effective if such notice has not been provided) stating the name and address of the assignee, identifying the Registrable Securities beneficially owned by such assignee.

The rights of the Investor under this Agreement may only be assigned, in whole but not in part, to an Affiliate of Brookfield who at the time of such assignment agrees with the Issuer in writing to be subject to and bound by all the terms and conditions of this Agreement.
