				change" (as defined in the Preliminary Prospectus Supplement) that occurs prior to
				the 30 th	scheduled trading day preceding the Purchase Contract Settlement Date,
				each holder of a purchase contract, subject to certain conditions described in the
				Preliminary Prospectus Supplement, will have the right to accelerate and settle the
				purchase contract early on the fundamental change early settlement date (as defined
				in the Preliminary Prospectus Supplement) at the settlement rate determined as if the
				applicable market value were determined, for such purpose, based on the market
				value averaging period starting on the 23 rd scheduled trading day prior to the
				fundamental change early settlement date and ending on the third scheduled trading
				day immediately preceding the fundamental change early settlement date, plus an
				additional make-whole amount of shares (such additional make-whole amount of
				shares being hereafter referred to as the "make-whole shares"). This right is referred
				to as the "fundamental change early settlement right."

				change early settlement will be determined by reference to the table below, based on
				the date on which the fundamental change occurs or becomes effective (the
				"effective date") and the "stock price" (as defined in the Preliminary Prospectus
