Codexis, Inc. (Nasdaq:CDXS), a developer of cost-advantaged processes for the production of biofuels, bio-based chemicals and pharmaceuticals, today announced that the company has signed an Exclusive Negotiation Agreement with Shell. Under this agreement, Shell has agreed to negotiate exclusively with Codexis through September 1, 2012 the terms of a new agreement under which Shell would grant to the company certain rights and licenses in the biofuels field to develop and sell cellulase enzymes to third parties on a worldwide basis, except Brazil. Codexis has exclusive rights to commercialize its cellulase enzyme technology in all other fields. “Currently, Codexis’ cellulase enzyme technology can only be commercialized in the advanced biofuels field through Shell and its affiliates. If we finalize a new agreement with Shell as we currently anticipate, the rest of the world’s second generation biofuels producers will now also be available as target customers for our cost effective cellulase enzyme technology,” said John Nicols, Codexis’ President and Chief Executive Officer. Codexis and Shell also agreed under the Exclusive Negotiation Agreement that, beginning on August 31, 2012, Shell can elect to reduce between 13 and 48 full-time employee equivalents (FTEs) under the Codexis – Shell Collaborative Research Agreement on one day notice. Previously, the required notice period for this type of FTE reduction was 90 days. If Shell were to provide Codexis with an FTE reduction notice on or after August 31, 2012, Codexis expects that it would take appropriate cost reduction measures to reduce its operating expenses.
