Global Bioenergies, Audi to develop biofuel

January 21, 2014, Evry, France – Global Bioenergies
announces the signature of a collaboration with the German car-manufacturer
Audi on the development of isobutene-derived isooctane, a high performance
biofuel for gasoline engines.

Global Bioenergies, a NYSE Alternext Paris listed company
(ALGBE), is a pioneer in the development of processes for the direct and
cost-efficient transformation of renewable resources into light olefins, the
key building blocks of the petrochemical industry. Its most advanced program
consists in the production of bio-isobutene, a molecule with multiple
applications, one of which allows its transformation into isooctane, the gold
standard for gasoline engines (octane number 100). As a 100% drop-in fuel, it
can be used in any blending ratio with all standard fuels for gasoline motors.
It does not present the drawbacks associated with alcohol-based biofuels such
as ethanol or isobutanol which lead to limited blending ratios and lower
mileage per liter.

Audi is a frontrunner at implementing sustainable solutions
for all aspects directly linked to its products. Three parameters are key to
Audi in pushing forward the development of new biofuels: the quality of the
fuel to ensure optimal compatibility with its engines, the environmental
footprint in particular regarding CO(2) emissions and the requirement to use
feedstock not in competition with eatable resources.

Thomas Buhl, Head of Business Development at Global
Bioenergies comments: "We had recently announced the start of our
pre-commercial pilot phase at the Fraunhofer CBP in Leuna allowing obtaining
high-purity isobutene which can be used for different applications. One crucial
point of our collaboration with Audi will consist in supplying them with
isooctane derived from our isobutene to be produced at that pilot. Furthermore,
the collaboration with Audi will enable us to emphasize even more the usage of
sustainable feedstock."

During the two-year collaboration, this agreement also
foresees the possibility for Audi to acquire shares of Global Bioenergies
corresponding to less than 2% of its capital.
