Letter of Gratitude from IHI Infrastructure Systems Co., Ltd.

June 20^th, 2012

In 2012, our client IHI Infrastructure Systems Co., Ltd. was put in charge of the construction of a large-scale water gate in Tsubame City of Niigata Prefecture, called the "Ohkozu Moveable Dam" project, by the Hokuriku Regional Development Bureau of the Japanese Ministry of Land, Infrastructure, Transportation and Tourism. We received a formal thank you letter from IHI Infrastructure Systems in recognition of our company's contributions to this project.

We continually strive to be helpful to our customers, and we are proud to add this project to our list of accomplishments.
