MENA region and in particular, the Kingdom of Saudi Arabia which represents a very lucrative
and sustainable market for CORRE’s services. Also, our other strategic partnerships and
alliances have enabled us to expand our service platform to contain drill cuttings treatments,
automated oil storage tank cleaning, innovative soil remediation techniques and oil recovery
technology, as well as gain a foothold in the MENA region.”

Mr. Alex Gress, CFO and Senior Vice-President of CORRE, added “CORRE’s status through our
SAR-CORRE MENA partnership as a select pre-qualified company for the Kuwait Oil Company’s
soil remediation contracts we are currently bidding for, as well as the upcoming Oil Lakes
contracts, demonstrates the growing understanding of the value of our oil-remediation technology
and services. This infusion of working capital will continue to help us build on the positive
momentum we have already gained.”
