ANSAC Lifts Force Majeure Status

August 10, 2011

We are pleased to confirm that the circumstances giving rise to our force majeure declaration have passed and we are now able to lift that declaration.

We are resuming normal deliveries of all volumes remaining under our agreements with customers, less the amounts that we had to cancel because of those circumstances. We regret any inconveniences this may have caused and appreciate the understanding and cooperation of our valued customers.
