[1] Settlement in cash on the respective expiration dates would result in us receiving an amount ranging from zero, if the market price per share of our common stock is at or below the low strike price, to the maximum amount if the market price per share of our common stock is at or above the high cap price. If share settlement were elected, the number of shares received would be determined by the value of the capped calls at the time of settlement divided by the share price on the settlement date. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration.
