TESTIMONIAL - PROFESSOR CORRE OF UNIVERSITY OF PHILIPPINES

July 18, 2002

To Whom it May Concern;

I have had the opportunity to do research with and observe the performance of two of your company's products, BZT® Aquaculture and BZT® Waste Digester, in large commercial aquaculture operations. Both of these products performed exceptionally well in a recent 3-year study sponsored by the United Nations Development Project and the Department of Science and Technology (UNDP-DOST Gainex Project), in which I was a principal investigator, to address viable solutions to improve the sustainability of high density shrimp farming operations. In this study, BZT® Aquaculture and BZT® Waste Digester provided numerous benefits to the shrimp ponds, including reduced bottom solids, phytoplankton stability, and increase in growth, survival, and total production of shrimp.

My current research with these products has shown that they consistently perform well when used as directed, and may even be utilized to control Vibrio and other luminous bacteria.

Sincerely,

Valeriano L. Corre, Jr.
