TOTAL

Total (CAC: TOTF.PA) (Paris:FP) (LSE:TTA) (NYSE:TOT) and SunPower Corp. (NASDAQ: SPWRA, SPWRB) today confirmed their intention to close Total’s all-cash tender offer, to purchase up to 60 percent of the outstanding shares of Class A common stock and 60 percent of the outstanding shares of Class B common stock of SunPower for $23.25 per share respectively, as scheduled on June 14, 2011.

In line with this intention, the two companies have waived the condition related to receipt of European Union competition law approval, as permitted by applicable European Union regulations. With the grant of this waiver by the two companies, all regulatory conditions to the completion of the tender offer are currently satisfied. All other terms and conditions of the tender offer remain unchanged.

Total and SunPower have amended the terms of the previously announced tender offer agreement and related agreements to reflect the waiver and certain other related matters.

The offer period will thus expire at 12:00 midnight, New York City time, on June 14, 2011 unless the offer is further extended.
