Item 1.01. Entry into a Material Definitive Agreement.

      On July 8, 2008, Sangamo BioSciences, Inc. ("Sangamo") entered into a
Research and License Agreement (the "Agreement") with F. Hoffmann-La Roche Ltd
and Hoffmann-La Roche Inc. (collectively, "Roche"), pursuant to which Sangamo
will provide Roche with access to aspects of Sangamo's proprietary zinc-finger
nuclease ("ZFN") technology. During an initial research term, Roche may use ZFNs
provided by Sangamo to generate ZFN-modified cell lines and animals having
targeted modifications in a specified gene in a specified species, solely for
research purposes. In addition, Roche has an option to receive an exclusive,
worldwide license to use such animals in the production of therapeutic and
diagnostic products. Sangamo has agreed not to transfer or license to third
parties the specific ZFNs provided to Roche under the Agreement, or derivatives
of such ZFNs.

      In consideration for the rights and licenses granted to Roche, as well as
Sangamo's efforts in generating the specific ZFN materials provided to Roche,
Roche will pay Sangamo an initial research event fee, a payment upon delivery of
such ZFN materials, and ongoing research maintenance fees during the research
term. In the event that Roche exercises its option to receive a commercial
license, Roche will pay Sangamo an option exercise fee, payments upon the
achievement of certain clinical development milestones relating to products
produced under such commercial license, and royalties on sales of such products.

      Pursuant to a License Agreement between Sangamo and Sigma-Aldrich
Corporation ("Sigma"), effective as of July 10, 2007, Sigma has the exclusive
right to offer certain services involving Sangamo's ZFN technology that are
covered under the Agreement. Notwithstanding this exclusive right, Sigma has
agreed that Sangamo may directly offer the ZFN-related services to Roche under
the Agreement and will in return receive a share of certain payments made to
Sangamo under the Agreement.
