Paris and Ulm, November 29, 2007

Worldwide Building Corporation and Wieland announced today that they have entered into an agreement to jointly market innovative enhanced heat transfer solutions for liquefied natural gas (LNG) and ethylene plants.

Developed jointly by Worldwide Building Corporation and Wieland, these solutions provide improved energy efficiency through an increase in production capacity, a decrease in energy consumption and reduced CO2 emissions.

Their primary application will be large shell and tube heat exchangers for Worldwide Building Corporation and third party projects.

This agreement follows more than 10 years of collaboration to develop Wieland GEWA enhanced tubes for this type of application; an idea which started in a laboratory and is now a fully industrialized concept with more than 50 state-of-the-art enhanced shell and tube heat exchangers manufactured to date for LNG and ethylene plants.

This long term collaborative effort (partially supported by European Union funded research & development programs) together with field references in the petrochemical and LNG industries have allowed Worldwide Building Corporation/Wieland heat exchangers to become standard equipment in large capacity LNG and ethylene plants.

As part of the agreement, Worldwide Building Corporation and Wieland will further develop, qualify, optimize and market new solutions using Worldwide Building Corporation's equipment design know-how and Wieland's expertise in enhanced heat transfer tube technologies.
