Long Time Ethanol Industry Advocate Brings Leadership Experience to Mascoma

CAMBRIDGE, Mass. -- Mascoma Corporation, a leader in cellulosic biomass-to-biofuels development and production, today announced former United States Senator Tom Daschle has joined the company's Board of Directors. Senator Daschle represented South Dakota, and is the one of the longest serving Senate Leaders in history, holding the position from 1994 to 2005. He is a longtime ethanol advocate who has sponsored legislation and led Congressional measures to advance the renewable fuels industry.

"Senator Daschle brings substantial leadership, ethanol industry and public policy experience to Mascoma. He will help us think strategically about our business and bring relationships needed to develop production facilities," said Mascoma CEO Bruce Jamerson. "I have known Tom for several years and am excited to be working together with him. He is an excellent addition to our Board of Directors."

"Mascoma has a first class team of executives, scientists and researchers, and investors, complemented by leading technology for the operation of commercial cellulosic ethanol plants," said Daschle. "As a U.S. Senator, I supported numerous public and private efforts to advance the corn ethanol industry in the Midwest, to the point that this is now a multi-billion dollar, domestic renewable fuels industry. I look forward to working with Mascoma, its investors, and its public and private partners to create a complementary cellulosic ethanol industry that spans the entire country, and other locations throughout the world."

"Senator Daschle provides Mascoma with significant government and industry expertise for the emerging market in cellulosic ethanol. Tom shares in our vision that cellulosic ethanol is key to reducing our nation's dependence on foreign oil and our own greenhouse gas emissions," said Vinod Khosla of Khosla Ventures, a founding Mascoma investor. "With this additional expertise in public policy, along with our existing executive, scientific and investor support, we are well positioned to play a significant role in this industry."

Tom Daschle is Special Policy Advisor in the Washington, D.C. office of Alston & Bird, a legal firm with a commitment to innovation and technology in a global economic environment. He is also a Distinguished Fellow at the Center for American Progress. Senator Daschle recently joined former Senate Majority Leaders Howard Baker, Bob Dole, and George Mitchell to form the Bipartisan Policy Center, where he and Senator Dole led the 21st Century Agriculture Policy Project. Previously, he served more than 25 years in the U.S. House of Representatives and Senate where he acted as both Senate Minority and Majority Leader for 10 years. He played an instrumental role in the development of U.S. legislative and regulatory policies.
