The Registration Rights Agreement also provides the Selling Shareholders with the right (the "Piggyback Registration Right") to require the Company to include Registrable Securities in any future public distribution of Class A Shares in Canada or the United States undertaken by the Company (a "Distribution"). The Company shall include in a Distribution all of the Registrable Securities the Selling Shareholders request to be included therein pursuant to the Piggyback Registration Right; provided, however, that if the Distribution occurs by way of an underwritten offering and the managing underwriter(s) advises the Company that, in their opinion, the total number of Class A Shares to be included in such Distribution should be limited for certain prescribed reasons, the Class A Shares to be included in the Distribution shall first be registered for the account of the Company.

In connection with an underwritten offering, the Company will agree to refrain from issuing any equity securities of the Company for a period of up to 60 days, subject to customary exceptions. The Company will generally be responsible for all reasonable expenses under the Registration Rights Agreement, excluding any underwriting discounts or commissions on any Registrable Securities sold by a Selling Shareholder.
