Sionix' Interim Chairman James W.

During the last several weeks Sionix has made significant progress executing on its goals. The $1,025,000 financing we have secured, as well as the going-forward financing commitments, now provide Sionix the resources to more aggressively pursue our proactive business development strategies. These investors have shown confidence in the Sionix plan as well as our personnel.

The above shareholder letter stated, We have been pursuing opportunities in a variety of markets. They each have different needs and economics and require a highly tailored approach. We will continue on this path.

I believe our recently signed lease agreement with Crown Maple Syrup, Inc. is good evidence of Sionix' ability to evaluate and resolve a variety of fluids challenges. Finally, we are moving ahead with our business development plans in the Williston Basin region of North Dakota. This capital facilitates our strategy in this booming area."

About Sionix Technology

The Sionix Mobile Water Treatment System for fluids management and water treatment addresses a broad spectrum of contaminant conditions in totality. Using a customized technology configuration, each system tailors its technology suite to address each customer's specific treatment needs. The dynamic nature of influent contamination dictates treatment parameters which may continually be in flux. The modularity of the technology suite within the Sionix MWTS allows for the ease of adaptation to these fluctuating contaminant conditions. A unique component highlighted within the Sionix systems is the Sionix patented and proprietary Dissolved Air Flotation technology, which generates micro bubbles between the size of 1 and 2 microns, compared to historical sizes of 50 microns or larger. The actions of these micro bubbles facilitate the removal of 99.95% of organic contaminants and a majority of inorganic contaminants. The evolution of this technology is exclusive to the Sionix Water Treatment Systems.
