Curtis WR, Growing cells in a
reservoir formed of a flexible sterile plastic liner,
U.S. Patent #6,709,862, March 23, 2004.
Potential increase in NG value per Billion cu. Ft.
$3,000 (Transport Fuels: 167%)
$60,000 (High Value Lubricants: 1,300%)
$200,000+ (Cosmetics: 4,400%)
How big is the opportunity?
• Market Characteristics
• Oil/gas Shale Boom
• Volatile market and record-low
natural gas prices
• Expansive shale reserves
• 100-200 Tcf recoverable
• Estimated 7 billion cubic feet of
natural gas flared in US (2011)
• Current wells out of production
• Many wells are not bringing gas
to market due to economics
• Decentralized and Remote well sites
• Topography and vast area of PA
prevents new gas distribution
infrastructure
Remote gas reserves

Why are we doing it?
• Leveraging technology developed under ARPA-E Electrofuels
program fixing biofuels from H2 and CO2
• High-efficiency conversion of gas phase to high quality biofuels
• High-throughput chemical screening of genetically tailored organisms
• Current syngas to liquids is based on 100 year old technology
• Fischer-Tropsch liquefaction requires large-scale, high cost equipment
• Current syngas bioreactor systems produce alcohols
• Difficult product separation, lower value product line
• Our group has experience with fatty acid wax esters
• Wax esters are currently being marketed for high-value lubricants and
cosmetics
• Rapidly developing oil-shale with un-utilized “producer gas”
• Flared gas in the U.S. is exponentially increasing (increased by $315
Million in potential revenue from 2010 to 2011)
Technology Overview
• A low-cost trickle-bed bioreactor is poised
to be the only leading technology capable
of upgrading natural gas to liquids at such
a small scale
• Genetic modifcation of Clostridium
ljungdahlii with Jojoba wax ester pathway
• 97+% biological conversion of gas
• 87+% Conversion to product
• 13% used for biological functions
97%+ Syngas Yield Requires
1 ) Zero outputs except BioFuel
“Dead End Fermentation”
2) Ultra-Low Dilution Rate
“Growth Disassociated Fuel
Production”
3) Secreted Hydrophobic Product
Plastic-Lined Lab-scale Trickle Bed Fermenter

Our Competitive Advantage
• Centralized, large-scale processing still requires natural gas
distribution infrastructure
• On-site liquefaction requires minimal gas handling
• Production of alcohol requires distillation
• Our continuous process phase separates our product through decantation
• Trickle-bed fermenters have ultra efficient gas-to-liquid mass transfer
with minimal operational cost
• Trickle-beds are much larger (90%) than conventional stirred tank fermenters
• Our patent allows us to have maximum efficiency with minimal capital cost

Strategic Partner Possibilities
• Unique strategic partner for syngas production from methane
• Steam reforming of Methane to syngas has been cost prohibitive at small to
medium scale
• Reduction is CapEx for small scale autothermal methane reforming is necessary for
economics
• The high specificity of transgenic bacteria allow our group to tailor
products to our partners and customers
• We have modified our current product lines (fuels) to include higher value
lubricants.
• We will seek to partner with synthetic lubricant manufacturer (such as
Mobil-1)
• Enable wax-ester product lines during scale-up
• Further test product lines for higher value applications such as cosmetics
