Thompson Creek is offering to exchange 5.8458 shares of Common Stock for each validly tendered and accepted TMEDS unit pursuant to the Exchange Offer (the "Exchange Ratio"). The number of shares of Common Stock to be exchanged for each unit of TMEDS was fixed after 5:00 p.m., New York City time, on June 20, 2014 (the "Pricing Date") on the basis of the pricing formula set forth in the Offer to Exchange described below. The Exchange Ratio is equal to the sum of (i) 5.3879 shares of Common Stock plus (ii) a number of shares of Common Stock equal to $1.25 divided by $2.73, which is the five day arithmetic daily volume-weighted average price of the Common Stock over the trading period beginning on June 16, 2014 and ending on the Pricing Date. Fractional shares will not be issued in the Exchange Offer and holders will receive the cash value of any fractional shares due to them, which cash value shall be the product of the fractional shares to be received and $2.73. The settlement date for the Exchange Offer is expected to be June 25, 2014.

In addition to the Exchange Ratio, holders who participate in the exchange offer will receive the accrued portion of the $0.406250 quarterly cash installment payment that has accrued from May 15, 2014 to the settlement date of the Exchange Offer and that is payable in respect of the amortizing note component of each TMEDS unit. Such cash installment payment reflects both accrued interest and the partial repayment of principal in respect of the amortizing notes component of each TMEDS unit.

The Exchange Offer will expire at 11:59 p.m., New York City time, on June 24, 2014, unless extended or earlier terminated by the Company. Holders may withdraw units of TMEDS that they tender at any time before the Exchange Offer expires. In addition, holders may withdraw tendered units of TMEDS if the Company has not accepted them for payment within 40 business days from the commencement of the Exchange Offer. The tender and withdrawal of shares of TMEDS pursuant to the Exchange Offer held in "street" name are subject to compliance with the appropriate procedures of the automated tender offer program, or ATOP, of The Depository Trust Company.
