Metabolix to Locate New Joint Venture Office in Lowell, MA

Metabolix will locate the sales and marketing headquarters for its joint venture with ADM, Telles™, at Wannalancit Mills in Lowell

(Lowell, MA) – June 2, 2007 – Metabolix, Inc. (NASDAQ: MBLX), a leader in the use of bioscience to provide sustainable, clean solutions for plastics, fuels and chemicals announced that it will locate  the sales and marketing headquarters of its joint venture with Archer Daniels Midland Company, Telles™, in Lowell, Massachusetts. Metabolix has a signed a five year lease for 14,000 square feet of office space at Wannalancit Mills located at 650 Suffolk Street in Lowell.

Telles will produce Mirel™ natural plastics, a family of high performance natural plastics that are biobased, sustainable and completely biodegradable. Metabolix chose Lowell for Telles’s sales and marketing headquarters because of Metabolix’s close relationship with UMass Lowell.

“UMass Lowell has played a major role in our decision to locate here,” says Robert Findlen, Vice President of Sales and Marketing for Metabolix. “We are currently using the UMass laboratories for research and product development and we couldn’t think of a better, more appropriate location for Telles sales and marketing headquarters. Lowell is also an excellent location for entertaining clients because of its sports venues and restaurants.”  Findlen along with three other product developers for Telles are graduates of UMass Lowell’s Plastics Engineering School.

“This is an exciting time for Lowell,” says Lowell City Manager, Bernie Lynch. “We are finding that UMass Lowell’s R&D facilities are an anchor for attracting companies who are exploring product development in the area of plastics and nano-technology. We look forward to attracting more innovative companies to our city.”

Telles plans on moving into the space on June 1, 2007. Initially the space will house fifteen employees, and will be growing to a staff of over forty.
