Cobalt Biofuels

Letter from the CEO

March 24, 2008

The world population is growing and our local, national and global community is impacted by this growth. One of our major challenges as a society is to balance our energy infrastructure needs with the environmental impact on several different levels. We require energy to feed our population, we require fuel for transportation, and industries of developed and developing nations require low cost energy in order to grow.

The challenges of meeting those energy needs are many. Globally these challenges include; the availability of land and water for biomass, the pollution of air and water, changing rural and urban economies, greenhouse gases that can change our climate thus the water distribution on the planet, and finally limited resources for research and development of cost effective technologies for alternative energy sources such as biofuels, solar and wind.

Cobalt Biofuels is contributing to solving these challenges by making commercial scale biobutanol from biomass a sustainable reality. Our patented and proprietary technologies create favorable economics for the biorefinery business model by increasing productivity and reducing energy required in the production process. Our three major initiatives are to:

Cobalt Biofuels and the Next Generation Biofuel Industry

As an industry we need to create multiple sustainable sources of energy through the development of robust technology and sustainable business models to produce and distribute the energy we make. Cobalt's goal for biofuels as a sustainable industry begins with the production of biobutanol as a platform biofuel through a process that has been proven at large scale and with diverse feedstocks.

Cobalt technology can be applied to the utilization of local feedstock or large feedstock sources because our technology is feedstock type independent. This allows communities not able to grow corn due to water, land, and nitrogen issues to still produce biofuels locally.

In addition, butanol has been tested and will continue to be tested in the transportation fuel field. Biobutanol has been produced in large scale and because of its chemical properties, 4 carbons vs 2 carbons (ethanol) it can be integrated into the current petroleum refinery, pipeline, and engine infrastructure.

We are ready now to begin pilot production of biobutanol via Cobalt technology. Stay tuned for site and feedstock selection announcements.

Please use our website to learn more about our company and investors, the strategy for Cobalt's growth within the biofuels industry, and our technological approach to address the industry-wide challenges for next generation biofuels. We look forward to building a sustainable biofuels for the future of our world.

Warm Regards,
