International and Citi may, from time to time, enter into certain cash-settled
total return swaps (the "Swaps") with respect to the Common
Stock.&#160;&#160;Among other things, the Swap Agreement provides that all
transactions thereunder will not reference more than 9.9% of the outstanding
Common Stock.&#160;&#160;In connection with establishing and maintaining any

to a final valuation period preceding the termination of the Swap, and (ii) Citi
will be obligated to pay to Glencore International an amount in cash equal to
any dividends that would have been paid by the Company on the Common Stock
referenced by each Swap and make a cash payment to Glencore with respect to any
appreciation in the volume weighted average price of the Common Stock from the
initial averaging period for a Swap to the final valuation period preceding the
termination of the Swap.&#160;&#160;The overall effect of the Swap parties' cash
payments based on the price of the Common Stock referenced in the Swaps is to
provide Glencore International with economic exposure to price movements in the
number of shares of Common Stock referenced in the Swaps during the relevant
