Item 4 — Purpose of Transaction
Item 4 of the original Schedule 13D is hereby supplemented as follows: The Purchaser Reporting Persons disposed of an aggregate 8,600,000 Common Shares in a block trade pursuant to Regulation S under the U.S. Securities Act of 1933, as amended, for aggregate cash proceeds of approximately C$168,990,000 (excluding brokerage commission), at a price of C$19.65 per Common Share. The disposition of the Common Shares reported in this Amendment No. 6 more closely aligns the Reporting Persons' aggregate share ownership with certain thresholds under the Investment Agreement. Although the Reporting Persons have no current specific plan or proposal for further dispositions of the Common Shares, the Reporting Persons also may, at any time and from time to time, subject to compliance at all relevant times with the Investment Agreement, A&R Margin Loan Agreement and regulatory requirements and applicable securities laws, terminate in whole or in part, dispose of or distribute some or all of their Common Shares or such other securities they own or may subsequently acquire, depending on various factors, including the price of the Common Shares, terms and conditions applicable to any potential transaction, liquidity and diversification objectives of the Reporting Persons and such other factors that the Reporting Persons deem relevant at any time or from time to time.
