 SANGAMO BIOSCIENCES REPORTS 2006 FOURTH QUARTER AND YEAR-END FINANCIAL RESULTS

    RICHMOND, Calif., Feb. 8 /PRNewswire-FirstCall/ -- Sangamo BioSciences,
Inc. (Nasdaq: SGMO) today reported financial results for the fourth quarter
ended December 31, 2006. Revenues for the fourth quarter of 2006 were $2.2
million as compared to fourth quarter 2005 revenues of $1.4 million. The
principal components of fourth quarter 2006 revenues were from Sangamo's
research agreement with Dow AgroSciences (DAS), research grants and
partnerships in enabling technologies and human therapeutics.

    The consolidated net loss was $8.9 million, or $0.26 per share, as
compared to a net loss of $2.7 million, or $0.10 per share, in the same period
in 2005. As of December 31, 2006, the company had cash, cash equivalents, and
investments of $54.0 million.

    Total fourth quarter 2006 operating expenses were $12.0 million as
compared to $4.3 million in the prior year period. Research and development
expenses were $10.1 million for the three months ended December 31, 2006 and
$2.7 million for the same period in 2005. Research and development expenses in
the fourth quarter of 2006 were higher than in the same period of 2005 due to
Sangamo's acquisition of the Edwards Lifesciences (Edwards) ZFP Therapeutic
angiogenesis programs, increased expenses relating to our clinical trials
and employee stock-based compensation. In December 2006, Sangamo purchased
Edwards' ZFP Therapeutics programs in exchange for one million shares of
Sangamo common stock and certain royalties, a transaction valued at $5.8
million. General and administrative expenses were $1.9 million for the fourth
quarter of 2006 as compared to $1.6 for the same period in 2005. Total
expenses also included a non-cash charge of $493,000 during the fourth quarter
ended December 31, 2006 for employee stock-based compensation.

    Net interest income for the fourth quarter of 2006 was $698,000 as
compared to $293,000 in the comparable period of 2005.

    Twelve Month Results

    For the year ended December 31, 2006 revenues were $7.9 million as
compared to $2.5 million in 2005. The net loss for the year ending December
31, 2006 was $17.9 million, or $0.55 per share, compared to $13.3 million, or
$0.51 per share, for the year ended December 31, 2005.  Total operating
expenses for the years ended December 31, 2006 and 2005 were $28.6 million and
$16.2 million, respectively.  Total expenses for the year ended 2006 included
the $5.8 million expense associated with the acquisition of the Edwards ZFP
Therapeutic programs as well as a non-cash charge of $2.0 million for employee
stock-based compensation.  As of January 1, 2006 the Company adopted Statement
of Financial Accounting Standards No. 123R and is reporting employee stock-
based compensation expense in its GAAP results.



    As of December 31, 2006, the company had cash, cash equivalents, and
investments of $54.0 million, compared with $47.2 million at December 31,
2005.  Total shares outstanding at December 31, 2006 were 35.0 million as
compared to 30.6 million at December 31, 2005.

    Recent Highlights

    -- Initiation of Phase 2 clinical trial of SB-509 for diabetic neuropathy.
       In November 2006, Sangamo announced that it had initiated a
       multi-center, double-blind, placebo-controlled, Phase 2 clinical trial
       of SB-509 for diabetic neuropathy (DN) designed to evaluate the
       clinical safety and clinical effects of repeat administration of SB-509
       in diabetics with mild to moderate diabetic peripheral sensory motor
       neuropathy in the legs.  The Juvenile Diabetes Research Foundation
       (JDRF) is providing up to $3 million of financial support for the study
       payable on achievement of certain milestones.  SB-509 is an injectable
       formulation of plasmid DNA that encodes a zinc finger DNA-binding
       protein transcription factor (ZFP TF(TM)), designed to upregulate the
       vascular endothelial growth factor A (VEGF-A) gene.

    -- Acquisition of Edwards' ZFP Therapeutic angiogenesis program.  In early
       December, Edwards and Sangamo announced Sangamo's acquisition of the
       Edwards ZFP Therapeutic angiogenesis program that was completed on
       December 22, 2006.   Edwards transferred the assets of these programs
       to Sangamo in exchange for 1 million shares of Sangamo common stock and
       royalties on certain Sangamo products commercialized in the
       future based upon ZFP activation of the VEGF gene.  In addition to
       acquiring two clinical stage programs in peripheral artery disease
       (PAD), a pre-clinical program in ischemic heart disease (IHD) and ten
       grams of clinical grade drug, the agreement enables coordinated
       implementation of Sangamo's future clinical trials and corporate
       partnering opportunities.  Future clinical development plans for these
       assets will be discussed on today's conference call.

    -- Achievement of first milestones in agreement with Dow AgroSciences
       (DAS). In November 2006, DAS and Sangamo announced the successful
       completion of multiple research milestones as part of their Research
       and Commercial License Agreement initiated October 2005.

    -- Michael J. Fox Foundation for Parkinson's Research (MJFF) awards
       Sangamo funds to develop novel ZFP Therapeutic for the treatment of
       Parkinson's disease (PD). The $950,000 grant, which will be paid over a
       period of two years will be used to develop ZFP TFs to activate the
       expression of glial cell line-derived neurotrophic factor (GDNF), a
       potent neurotrophic factor that has shown promise in preclinical
       testing to slow or stop the progression of Parkinson's disease. Use of
       a ZFP TF to activate the GDNF gene in the brain -- as compared to
       addition of a GDNF cDNA or the recombinant protein -- may allow the
       delivery of a more physiologically relevant dose of the growth factor.
       This may be of particular significance when targeting potent natural
       growth factors such as GDNF, where sufficient but not super-
       physiological levels of the therapeutic protein may be required to
       achieve potency with safety.

    -- Sangamo and City of Hope (COH) announce license agreement and research
       collaboration to develop a treatment for brain cancer.  Sangamo entered
       into an exclusive, worldwide license agreement with COH for
       intellectual property related to a chimeric immunoreceptor useful in
       treating human cancers. Sangamo and COH also entered into a research
       collaboration to develop a novel cell therapy combining the licensed
       technology with Sangamo's proprietary zinc finger DNA-binding protein
       nuclease (ZFN(TM)) technology for treatment of glioblastoma multiforme
       (GM), a progressive and usually fatal brain cancer. Sangamo expects to
       file an IND for this program with the U.S. FDA in the second half of
       2007.
