&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt; &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;4. Terrane Acquisition &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;On October&amp;nbsp;20, 2010, TCM acquired 100% of the issued and outstanding equity of Terrane Metals Corp. ("Terrane"), an exploration and development company in British Columbia, Canada. TCM acquired Terrane by way of a plan of arrangement (the "Arrangement") pursuant to a definitive agreement dated July&amp;nbsp;15, 2010, and amended on August&amp;nbsp;20, 2010 (the "Arrangement Agreement"). Upon consummation of the Arrangement, Terrane became a wholly-owned subsidiary of TCM. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Terrane currently has interests in four mineral properties in Canada: 100% in Mt. Milligan, 100% in the Berg Property, 43% in the Maze Lake Property, and 51% in the Howards Pass Property. Mt.&amp;nbsp;Milligan is primarily a copper-gold deposit in the construction and development stage, which has been designed to be a conventional truck-shovel open pit mine. The Berg, Maze Lake, and Howards Pass properties are in the exploration stage. In acquiring Terrane, TCM diversified its current asset base of primary molybdenum deposits to include contributions from copper and gold subsequent to the commencement of Mt. Milligan, and exploration opportunities in the additional properties acquired. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Upon closing of the Terrane acquisition, the holders of Terrane's outstanding common shares received C$0.90 in cash and 0.052 of a TCM common share per Terrane share. As a result, TCM paid cash consideration of $410.5&amp;nbsp;million (C$420.5&amp;nbsp;million using the Bank of Canada noon rate on the date of closing), and issued 24.3&amp;nbsp;million shares at a fair value of $268.7&amp;nbsp;million based on the closing price of TCM's stock on the date of closing. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In addition, pursuant to the Arrangement Agreement, 63.2&amp;nbsp;million of outstanding Terrane Warrants as of October&amp;nbsp;20, 2010 will remain outstanding, of which 45.4&amp;nbsp;million expire on April&amp;nbsp;16, 2011 (the "2011 Warrants") and 17.8&amp;nbsp;million expire on June&amp;nbsp;21, 2012 (the "2012 Warrants"). Each Terrane Warrant remains outstanding, and, on its existing terms, entitles the holder (until the expiration) to receive, upon its exercise, the same share and cash consideration that the warrant holder would have received had the Terrane Warrant been exercised immediately before the effective time of the Arrangement. TCM has entered into supplemental indentures for the Terrane Warrants (other than those originally issued to Goldcorp Canada&amp;nbsp;Ltd.), which provide for an offset of the exercise price against the cash consideration that would otherwise be payable to the holder upon exercise of a Terrane Warrant. Upon exercise, the holders follow the same procedures that would have been followed prior to the effective date of the Arrangement, except that: (i)&amp;nbsp;in the case of the 2011 Warrants, which have an exercise price of C$1.50 (the "2011 Exercise Price"), the payment of the 2011 Exercise Price will be partially satisfied by offsetting the cash consideration otherwise payable to an exercising holder; and (ii)&amp;nbsp;in the case of the 2012 Warrants, which have an exercise price of C$0.85 (the "2012 Exercise Price"), the payment of the 2012 Exercise Price will be satisfied by offsetting the cash consideration otherwise payable to such holder. Accordingly, upon valid exercise of (i)&amp;nbsp;the 2012 Warrants, holders will not be required to deliver cash in satisfaction of the 2012 Exercise Price and will be entitled to receive cash in the amount of C$0.05 and the 0.052 TCM common share consideration for each 2012 Warrant exercised, and (ii)&amp;nbsp;the 2011 Warrants, holders will be required to deliver C$0.60 cash in satisfaction of the 2011 Exercise Price and will be entitled to receive the 0.052 TCM common share consideration for each 2011 Warrant exercised. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The fair value of the outstanding Terrane Warrants at closing of the Arrangement was $14.2&amp;nbsp;million based upon the closing price of those warrants on the date of closing of the Arrangement and the related foreign exchange rate. TCM accounts for these warrants as a derivative and recorded a loss related to the change in the fair value of the Terrane Warrants of $6.7&amp;nbsp;million for the fourth quarter and year ended December&amp;nbsp;31, 2010, of which no tax benefit was realized. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Fair Value Determination and Allocation of Consideration Transferred &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;As noted above, TCM paid $410.5&amp;nbsp;million of cash, issued common shares at a fair value of $268.7&amp;nbsp;million (excluding share issuance costs of $0.2&amp;nbsp;million), and assumed the outstanding Terrane warrants with a value of $14.2&amp;nbsp;million, for a total purchase price of $693.4&amp;nbsp;million. The acquisition is being accounted for under the purchase method of accounting, and TCM has allocated the purchase price of Terrane based upon the fair value of the net assets acquired and liabilities assumed at the acquisition date. TCM estimated the fair values of the assets acquired and liabilities assumed at the acquisition date in accordance with the business combination standard issued by the FASB.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;As of December&amp;nbsp;31, 2010, the allocation of the purchase price has been recorded using preliminary estimates related to the fair value of the mineral properties acquired. Given the close proximity of the closing date of the acquisition and the fiscal year-end, TCM has not been able to finalize the working capital adjustments, file final tax returns, and finalize the mineral property valuations. As a result, the following is a summary of the preliminary estimates of the fair value of the assets acquired less assumed liabilities: &lt;/font&gt;&lt;/p&gt;
