Each of the undersigned further understands that in connection with the IPO certain existing shareholders (the “Existing Investors”) and the Canada Pension Plan Investment Board (“CPPIB” and, together with the Existing Investors, the “Investors”) shall enter into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Company, to be dated as of the closing of the IPO (the “IPO Closing Date”), pursuant to which the Investors shall agree to certain transfer restrictions on their Common Shares.

5. Restrictions on Transfers by the Undersigned.
