6

Territory relevant products and services with respect to Diesel Catalysts for the HDU field; provided, however, that TKK hereby acknowledges and agrees that its ability to exercise its rights with respect to the HDU Technology shall in all events be subject to the provisions of Article 8.3 of the Shareholders’ Agreement.
