SANGAMO BIOSCIENCES REPORTS THIRD QUARTER 2008

FINANCIAL RESULTS

Richmond, California - October 29, 2008 - Sangamo BioSciences, Inc. (Nasdaq: SGMO) today reported third quarter 2008 financial results and accomplishments.

For the third quarter ended September 30, 2008, Sangamo reported a consolidated net loss of $6.3 million, or $0.15 per share, compared to a net loss of $4.3 million, or $0.11 per share, for the same period in 2007. As of September 30, 2008, the company had cash, cash equivalents and investments of $59.5 million. Subsequent to the end of the quarter, the company received $8.5 million in scheduled payments from collaborators.

Revenues for the third quarter of 2008 were $3.7 million, compared to $2.3 million for the third quarter of 2007. Third quarter 2008 revenues were primarily comprised of revenue recognition from the company’s collaboration agreements with Dow AgroSciences (DAS) and Sigma-Aldrich, enabling technology agreements in protein production and research grants. The revenue recognized for the third quarter of 2008 consisted of $3.2 million from collaboration agreements and $549,000 from research grants.

Research and development expenses were $7.6 million for the third quarter of 2008, compared to $5.9 million for the same period in 2007. The increase in research and development expenses for the third quarter of 2008 was primarily due to advancing the company’s clinical development programs in diabetic neuropathy and pre-IND programs to develop ZFP Therapeutics for the treatment of HIV/AIDS and glioblastoma, as well as increased research and development personnel costs. Non-cash stock-based compensation included in research and development expenses totaled $580,000 and $364,000 in the third quarter of 2008 and 2007, respectively.

General and administrative expenses were $2.6 million for the third quarter of 2008, compared to $1.7 million for the same period in 2007. The increase in general and administrative expenses was primarily due to increased personnel costs, including non-cash stock-based compensation which totaled $709,000 in the third quarter of 2008 compared to $202,000 in the same period in 2007.

Total operating expenses for the third quarter of 2008 were $10.1 million, compared to $7.6 million for the same period in 2007.

Net interest and other income was $42,000 for the third quarter of 2008, compared to $1.1 million for the same period in 2007. The decrease is due to lower average investment balances and lower interest rates as well as a foreign currency translation loss during the quarter.

Nine Month Results

For the nine months ended September 30, 2008, the consolidated net loss was $21.7 million, or $0.53 per share, compared to a net loss of $14.8 million, or $0.41 per share, for the nine-month period ended September 30, 2007. Revenues were $9.4 million for the first nine months of 2008, compared to $6.3 million in the same period in 2007. Total operating expenses were $32.5 million for the first nine months of 2008 and $23.5 million for the same period of 2007. The increase in operating expenses for 2008 was primarily associated with Sangamo’s clinical development programs in diabetic neuropathy and pre-IND programs to develop ZFP Therapeutics for the treatment of HIV/AIDS and glioblastoma, as well as increased research and development personnel costs and lab supply expenses.

Recent Highlights

Initiation of a Phase 2 clinical trial (SB-509-801) to evaluate SB-509 in subjects with Amyotrophic Lateral Sclerosis (ALS). ALS is a progressive, degenerative motor-neuron disease for which there are limited treatment options and no cure. The Phase 2 trial is a randomized repeat-dosing, open-label, multi-center study designed to evaluate the effect of intramuscular administration of SB-509 on the progression of the disease in subjects with ALS. In addition to gathering data on safety and tolerability of SB-509, the study will also evaluate stem cell mobilization in subjects with ALS receiving SB-509.

Presentation of additional data from Phase 1b study of SB-509 (SB-509-401) and interim data from Phase 2 study (SB-509-701) in subjects with diabetic neuropathy (DN). Additional data from the Phase 1b clinical trial (SB-509-401) were presented at the 44th Annual Meeting of the European Association for the Study of Diabetes (EASD), demonstrating a statistically significant (p=0.0016) positive correlation of 2 or more response endpoints in the SB-509 treated group compared with placebo treated subjects at day 180 post-treatment. Response endpoints were defined as greater than a 14% improvement in quantitative sensory testing (QST), greater than 0.8 meters/second (m/sec) improvement in NCV and greater than a 3 point improvement as judged by the Neuropathy Impairment Scale - Lower Limbs (NIS-LL). The trial was conducted in subjects with mild to moderate diabetic neuropathy over a six month period after a single administration of SB-509. Positive interim clinical data were also presented at the International Society for Cellular Therapy (ISCT) Europe Regional Meeting in Antwerp, Belgium from the Phase 2 trial of SB-509 (SB-509-701) conducted in subjects with moderate to severe DN who entered the trial with at least one “blocked nerve”. The data demonstrate recovery of sensory nerve conduction velocity (NCV) in 75% of SB-509 treated subjects compared to 25% of placebo treated subjects. SB-509 is an injectable formulation of plasmid DNA that encodes a ZFP transcription factor (ZFP TF^TM), designed to upregulate the vascular endothelial growth factor-A (VEGF-A) gene.

Official launch of Sigma-Aldrich CompoZr^TM platform of zinc finger nuclease (ZFN) reagents for gene-editing. In September, Sangamo’s partner, Sigma-Aldrich Corporation (Nasdaq: SIAL), the exclusive distributor of ZFP products for research applications, launched sales of CompoZr ZFN reagents. The CompoZr ZFN platform of reagents is expected to provide researchers with the ability to target and precisely manipulate the genome of living cells, resulting in cell lines or whole organisms with defined gene deletions, insertions, or corrections. Initially offered as a customized service for developing ZFNs for specific gene targets, the CompoZr ZFN platform will eventually include ZFN-based kits for targeted transgene insertion and a catalog of off-the-shelf reagents for commonly studied gene targets, gene families, and pathways.
