Joel Velasco Leaves UNICA After Three Years as Chief Representative for North America

SAO PAULO, January 7, 2011 - The Brazilian Sugarcane Industry Association (UNICA) announced today that
Joel Velasco, the organization's Washington, DC-based Chief Representative
for North America, is leaving the position he has held since 2007, to join
Amyris, Inc., as Senior Vice-President, External Relations.

"Joel has provided UNICA with wise counsel, effective strategy and solid
results. We wish him well at Amyris and will continue cooperating in the
future, as we pursue what will often be common objectives," said UNICA CEO
Marcos Jank. Velasco will remain an informal advisor to UNICA on matters
related to U.S. biofuels policy.

"I have been honored to represent such a transformative industry at a
particularly pivotal period. I am confident that our international successes
over these last three years will yield dividends not only to UNICA member
companies but to the communities they serve for years to come. As I embark on
a new challenge with Amyris, I look forward to supporting UNICA's
trailblazing work to promote an even more vibrant sugarcane industry in
Brazil and beyond," added Velasco.

During his tenure with UNICA, Velasco led the organization's effort to
expand the North American biofuel and sugar markets. Thanks largely to his
work, the Environmental Protection Agency (EPA) recognized sugarcane ethanol
as an "advanced renewable fuel" for its ability to cut 60% of greenhouse gas
emissions compared to gasoline, and the California Air Resources Board (CARB)
determined that sugarcane ethanol meets the state's Low Carbon Fuel Standard.
Moreover, his efforts contributed significantly to make UNICA a forceful
voice for reducing trade barriers and market distortions for biofuels.

With Velasco's departure, UNICA's activities in Washington will be
carried out by Leticia Phillips and Ana Carolina Lessa. The organization's
international activities will continue to be overseen by UNICA's Senior
Advisor to the President for International Affairs, Geraldine Kutas, based in
Brussels.

ABOUT UNICA

producers of sugar and ethanol in the country's South-Central region,
especially the state of Sao Paulo, which accounts for about 50% of the
country's sugarcane harvest and 60% of total ethanol production. UNICA
develops position papers, statistics and specific research in support of
Brazil's sugar, ethanol and bioelectricity sectors. In 2008, Brazil produced
