“An Update on Range Fuels’ Soperton Plant Project”

11

Range Fuels’ Focus

Commercial production of cellulosic biofuels, including cellulosic ethanol, and clean renewable power from renewable biomass that cannot be used for food, and is sustainable, low cost and in excess supply.

22

Range Fuels History

Formed in June 2006 by Khosla Ventures to commercialize cellulosic biofuels

Access to $82MM in federal and state funds and $80MM loan guarantee

Broke ground in Soperton, GA in November 2007 for first U.S. commercial cellulosic biofuels plant utilizing woody biomass

On April 1, 2008 announced the completion of an oversubscribed Series B round of private financing greater than $100 million

Range Fuels History

In January 2009 the U.S. Department of Agriculture awarded the company a conditional commitment for an $80 million loan guarantee. AgSouth Farm Credit, a leader in agricultural and rural loans and part of Farm Credit Services, will be the lead lending agency on the loan

In 2009 Range Fuels personnel are moving to Georgia and operating personnel will be hired

Cellulosic biofuels production from the Soperton Plant scheduled to commence Q2 2010

Limitations of Current Technology

Current production technologies use corn or sugarcane― Limited max. capacity (U.S. corn 15 BGY); tight margins― Import tax of $0.54/gallon for Brazilian ethanol

Food versus fuel― Low land efficiency for fuel production ― Sharp increase in feedstock prices ― Depleting water tables― Wide price fluctuations due to weather― Resistance from grocery and livestock industriesLower fossil energy ratio― Corn at 1:1.4― Sugarcane at 1:8― Cellulosic ethanol at 1:10

66

2005 Energy Policy Act Title XVII― Established aggressive support for renewables through RFS1

2007 Energy and Independence Security Act― RFS2 with emphasis on growth in cellulosic biofuels ― 36 BGY “renewable fuels” mandated by 2022

Includes 21 BGY “advanced biofuels,” with 16 BGY from “cellulosic biofuels

2008 U.S. Farm Bill― Programs targeted to all facets along the biofuels supply chain

Technology Development

4 generations of biomass conversion testing Pilot-scale― K2A Optimization Plant

~ 5,500 hours on wood feedstock> 2,200 hours alcohol production

Catalyst systems― CC10s (2)― CC100― ~ 30,400 test hours

K2A Optimization Plant CC1000 Catalyst Reactor

― CC400― CC1000

Technology vs. Competition

Dependent on supplier enzyme costs; High energy costs LowExternal Dependency

Locked in to initial feedstockAbility to utilize lowest-cost feedstock

Feedstock Cost

Limited by enzymesMultiple syngas derivativesProduct Options

Dilute solutions for fermentation increase total water usage

Competitive with advanced corn ethanol plants

Water Usage

Challenged by ability to process only a portion of biomass

Ability to process entirety of biomassYield (gallons/ton)

Enzymes feedstock-tailored; non-trivial to switch feedstock

Can vary by type, size, mix, moisture content; polyculture compatible

Benefits of Technology Extend to Flexibility in Feedstock Use

• Fiber structure is unimportant

• Focus on delivered energy cost ($/mmBtu)

Today – existing forestry resources― Pulpwood― Fuel chips ― Mill residuals

Additional phases and future plants― Getting more out of what’s there

o In forest residue and un-merchantable timbero Pre-commercial thinnings

― New sources of renewable biomasso Purpose grown trees o Herbaceous energy crops

― Other non-food biomass feedstocks― Maintain focus
