(Nasdaq:AMRS), a leading renewable chemicals company, and Firmenich SA, a
leading global flavors and fragrances company, have announced a significant
expansion of their collaboration to develop and commercialize renewable

"We are very pleased with the progress of our ongoing collaboration with
Amyris, grounded in our vision to be the leaders in renewable ingredients for
the flavor and fragrance market," said Patrick Firmenich, Chief Executive
Officer. "This partnership leverages Firmenich's world class biotechnology
platform within the F&F industry, enabled by our leading team of molecular
biologists and unique intellectual property, as well as, our deep client
intimacy and market understanding. Innovation and sustainability are critical
pillars of our business model. Thanks to this expanded partnership, we look
forward to consistently providing our clients with high-quality, sustainable,
and cost-competitive ingredients," emphasized Firmenich.

"We are excited to expand our productive collaboration with Firmenich," said
John Melo, Amyris President & Chief Executive Officer. "The rapid pace of our
targeted ingredient development so far confirms our ability to deliver a host
of disruptive, competitive ingredients to our partners and underscores the
strategic value of collaborations for Amyris."

Under a previous agreement established in November 2010, Firmenich funded
Amyris's research and development to produce up to three F&F ingredients, with
an initial fragrance oil targeted for commercialization in early 2014. Under
the new agreement, Amyris and Firmenich will jointly select additional target
F&F ingredients that Amyris will develop and manufacture. Firmenich will
market and distribute any ingredients resulting from the collaboration
exclusively in the F&F market. Both parties will share in the economic value
derived from the sale of these ingredients.
