Elevance Renewable Sciences Announces Joint Venture With Wilmar International to Build World Scale Biochemical Refinery

BOLINGBROOK, Illinois, June 28, 2010 - Elevance Renewable Sciences, Inc. (Elevance) announced today that it has
entered into an agreement to form a joint venture with Wilmar International
Limited (Wilmar), one of the largest global agribusiness groups, to construct
a world scale biorefinery. The joint venture will use Elevance's proprietary
biorefinery technology to produce high-value performance chemicals, advanced
biofuels and oleochemicals. Large existing and rapidly emerging new demand
exists for these products in surfactants, antimicrobials, lubricants,
renewable biodiesel and green jet fuels.

This commercial-scale manufacturing facility will begin with a capacity
of 180kMT (approximately 400 million pounds) with the ability to expand up to
360kMT (approximately 800 million pounds) of products. The facility will be
located within Wilmar's new integrated manufacturing complex now under
construction in Surabaya, Indonesia.

The new plant is expected to come online in 2011, and like all facilities
based on Elevance's biorefinery technology, it will be capable of operating
using multiple renewable oil feedstocks, such as palm, mustard, soybean,
jatropha or waste oils.

Once operational, the biorefinery will produce green olefins, including a
unique distribution of alpha and internal olefins for chemicals and advanced
fuels; novel multifunctional esters and acids, including 9-decenoic acid, as
well as a premium mixture of oleochemicals and advanced biofuels.

"Elevance's unique technology fits our current business and asset
footprint very well and provides an exciting growth opportunity. It is a very
capital-efficient way to enhance the value of the renewable resource
feedstocks we produce," said Rahul Kale, Head of Biofuels and Oleochemicals
at Wilmar. "We look forward to working together to develop and deploy the
technology at our facility."

"As a leader in producing, refining, and marketing renewable feedstocks,
Wilmar represents an ideal partner for the first commercial-scale biorefinery
that Elevance will be investing in," said K'Lynne Johnson, CEO of Elevance.
"Wilmar's extensive capabilities and existing operations in Asia will allow
us to quickly build and begin operating an integrated facility, accelerating
the delivery of cost-effective, high-performing, renewable-based specialty
chemicals to the market. This joint venture represents the next step in
growing Elevance internationally."

The joint venture is subject to certain conditions such as relevant
government approvals.
