ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT. On December 4, 2006, Sangamo BioSciences, Inc. ("Sangamo") entered into an Asset Purchase Agreement (the "Agreement") with Edwards Lifesciences LLC, a Delaware limited liability company ("Edwards"), pursuant to which Sangamo will acquire all of the assets in Edwards' angiogenesis program including regulatory filings, clinical data, and GMP product (the "Transaction"). Under the Agreement, as partial consideration for the sale of such assets, Sangamo will issue to Edwards one million shares of its Common Stock, par value $0.01 per share (the "Shares"). As additional consideration for the sale, Sangamo agrees to pay Edwards royalties generated by the sales of certain human therapeutic products, including products to treat ischemic cardiovascular and vascular disease and diabetic neuropathy, based upon zinc finger protein (ZFP) activation of the vascular endothelial growth factor (VEGF) gene, the first of which product is not expected to be available for sale before 2012. The amount of royalties payable to Edwards is equal to (i) five percent (5%) of the net sales of each such product sold by Sangamo and (ii) the greater of (a) five percent (5%) of the net sales of each such product sold by a sublicensee of Sangamo or (b) twenty-five percent (25%) of the royalty payment received by Sangamo from its sublicensee on account of such product sold by such sublicensee; provided that total royalties paid by Sangamo under the Agreement shall not exceed $20 million in any calendar year or $100 million in the aggregate.

                                                                    Exhibit 99.1

             EDWARDS' ANGIOGENESIS PROGRAM TO BE ACQUIRED BY SANGAMO

  Agreement Transfers Edwards' ZFP Therapeutics Program to Sangamo and Enables
              Coordinated Implementation of Future Clinical Trials

    IRVINE, Calif. and RICHMOND, Calif., Dec. 4 /PRNewswire-FirstCall/ --
Edwards Lifesciences Corporation (NYSE: EW) and Sangamo BioSciences, Inc.
(Nasdaq: SGMO) jointly announced today that the two companies have entered into
a definitive asset purchase agreement under which Sangamo will acquire Edwards'
angiogenesis program. The Edwards program was originally initiated in 2000 in
collaboration with and under license from Sangamo using their proprietary zinc
finger protein (ZFP) platform. Under the agreement announced today, Edwards will
transfer the assets of its program to Sangamo in exchange for 1 million shares
of Sangamo common stock. Edwards will also receive royalties on certain products
commercialized in the future based upon ZFP activation of the vascular
endothelial growth factor (VEGF) gene. The transaction is expected to be
completed by December 31, 2006.

    "This transaction with Sangamo provides for focused, combined development of
our respective ZFP therapeutics programs and resolves the ongoing issue between
the two parties regarding the scope of our respective rights," said Michael
Mussallem, Edwards' chairman and CEO. "We're proud that our program has
developed products with the potential to help patients dealing with ischemic
vascular and cardiovascular disease. Additionally, the transfer of these assets
allows these important programs to continue under Sangamo's stewardship and
frees up additional Edwards' resources to drive R&D priorities more central to
our strategy."

    "We are excited about the opportunity to add an additional clinical stage
ZFP therapeutic program to our portfolio," said Edward Lanphier, founder,
president and CEO of Sangamo BioSciences. "We initiated this program in 2000 and
are pleased with the significant investment and progress that Edwards has made
in the past six years. In addition to acquiring two clinical stage programs in
peripheral vascular disease (PAD) and a late stage pre-clinical program in
ischemic heart disease (IHD), this agreement will have a significant impact on
Sangamo's future corporate partnering opportunities involving VEGF-ZFP
therapeutic programs."

    In January of 2000 Edwards, then a division of Baxter International, entered
into an exclusive license and research funding agreement with Sangamo to develop
and commercialize VEGF-ZFP therapeutics for the treatment and prevention of
ischemic cardiovascular and peripheral vascular diseases. Edwards completed
pre-clinical efficacy and toxicology studies and initiated a Phase 1 clinical
trial in June of 2004 for EW-A-401, a drug based on the VEGF-ZFP transcription
factor and designed to treat critical limb ischemia (CLI) as well as
intermittent claudication, both painful and limiting conditions of vascular
disease. Edwards has stated that early results from the CLI trial have been
encouraging and has submitted for approval with the U.S. Food and Drug
Administration to begin a randomized, placebo controlled, repeat dosing Phase 2
clinical trial in patients with CLI.

    Independently, Sangamo has initiated clinical trials in diabetic neuropathy
with a VEGF-ZFP therapeutic known as SB-509. SB-509 and EW-A-401 are nearly
identical in design and function. Sangamo recently announced that it has
initiated a multi-center, double-blind, placebo controlled, repeat-dosing Phase
2 clinical trial in patients with diabetic neuropathy.

    Sangamo and Edwards will host a conference call at 9:00 a.m. EST, Monday,
December 4, 2006. The conference call dial-in numbers are 866-543-6411 for
domestic callers and 617-213-8900 for international callers. The passcode for
the call is 10338848. Participants may access the live webcast via a link on the
Sangamo BioSciences website
http://phx.corporate-ir.net/phoenix.zhtml?c=120938&p=irol-IRHome in the Investor
Relations section under "Company Overview." For those unable to listen in at the
designated time, a conference call replay will be available for one week
following the conference call, from approximately 11:00 a.m. on December 4, 2006
to December 11, 2006. The conference call replay numbers for domestic and
international callers are 888-286-8010 and 617-801-6888 respectively. The
conference ID number for the replay is 16084942. The webcast will be available
on the Sangamo website for two weeks after the call.

About Sangamo BioSciences Sangamo BioSciences, Inc. is focused on the research and development of novel DNA-binding proteins for therapeutic gene regulation and modification. The most advanced ZFP Therapeutic(TM) development program is currently in a Phase 2 clinical trial for evaluation of safety in patients with diabetic neuropathy. Phase 1 clinical trials are ongoing to evaluate a ZFP Therapeutic for peripheral artery disease. Other therapeutic development programs are focused on ischemic heart disease, neuropathic pain, cancer and infectious and monogenic diseases. Sangamo's core competencies enable the engineering of a class of DNA-binding proteins known as zinc finger DNA-binding proteins (ZFPs). By engineering ZFPs that recognize a specific DNA sequence Sangamo has created ZFP transcription factors (ZFP TF(TM)) that can control gene expression and, consequently, cell function. Sangamo is also developing sequence-specific ZFP Nucleases (ZFN(TM)) for therapeutic gene modification as a treatment for a variety of monogenic diseases, such as X-linked SCID and hemophilia, and for infectious diseases, such as HIV. Sangamo has established several Enabling Technology Agreements with companies to apply its ZFP Technology to enhance the production of protein pharmaceuticals.
