Amyris to Enter Partnership to Supply Renewable Jet Fuel to GOL Airlines

Leading Airline in Brazil Seeks to Use Amyris's Sugarcane-Derived Jet Fuel
Following Industry Validation and Regulatory Approvals

SAO PAULO, BRAZIL, Oct. 23, 2013 (GLOBE NEWSWIRE) -- Amyris, Inc.
(Nasdaq:AMRS), a leading renewable fuels and chemicals company, and GOL Linhas
Aéreas Inteligentes S.A. (BM&FBOVESPA:GOLL4) (NYSE:GOL), the largest low-cost
and low-fare airline in Latin America, announced the signing of a memorandum
of understanding that could pave the way for GOL commercial flights to use
Amyris renewable jet fuel in 2014. The anticipated partnership was announced
during the first commercial flight with a renewable jet fuel in Brazil by the
airline earlier today.

"GOL is committed to making commercial aviation more efficient and
sustainable. Our experimental flight with renewable jet fuel at the Rio+20 in
2012 was an important step to guide our work. Today, we advance one more
step," said Adalberto Bogsan, Vice President of GOL.

Under the memorandum of understanding, GOL and Amyris will work together to
establish a framework for bringing Amyris renewable jet fuel produced from
Brazilian sugarcane to GOL's commercial flights following regulatory approvals
and validation by standard-setting bodies, including ASTM International and
Brazil's Oil, Gas and Biofuels Agency (ANP).

The partnership, under of auspices of the Brazilian Biofuels Platform, an
industry and government-supported initiative to encourage the use of renewable
fuels in aviation, was announced at Brazilian Aviation Day celebration, which
included participation of Brazil's Secretary of Civil Aviation, Minister
Moreira Franco, and a number of industry stakeholders including Brazilian
Airlines Association (ABEAR), Brazilian Biodiesel and Biojet Association
(UBRABIO), GE, and Boeing among others.

"GOL supports all initiatives to help make Brazilian aviation more
sustainable," says Paulo Kakinoff, President of GOL. During this past year,
the airline's fuel saving initiatives have helped it to reduce greenhouse gas
emissions by over 30 thousand tons.

Lifecycle analysis indicates that the Amyris renewable jet fuel could reduce
greenhouse gas emissions by 80% or more when compared to convention
fossil-derived jet fuel. Amyris has applied for certification under the
Roundtable of Sustainable Biomaterials (RSB) and is a member of Bonsucro, the
world's leading sugarcane sustainability standard.

"We are committed to working with the aviation industry to bring cleaner
skies, starting in Brazil in 2014. Following two successful demonstration
flights and a series of successful tests with multiple industry stakeholders,
we look forward to receiving ASTM validation and ANP approval of our
breakthrough renewable jet fuel produced from Brazilian sugarcane," said John
Melo, Amyris's President & CEO.

Amyris operates a production facility, located adjacent to the Paraíso
sugarcane mill in Brotas, São Paulo in Brazil, to convert sugars into a
renewable hydrocarbon, farnesene, which can be processed into a drop-in
renewable jet fuel compliant with Jet A/A-1 specifications following
regulatory and industry approvals.

During 2013, GOL completed a number of projects and has established even more
solid partnerships. In September, GOL participated in the launch of the Céus
Verdes do Brasil Project ("Brazilian Green Skies" in Portuguese), which aims
to improve the efficiency of Brazilian airspace. And today, GOL makes history
by being the first airline to make a commercial flight with a renewable jet
fuel in Brazil.
