RESEARCH TRIANGLE PARK, North Carolina – Precision BioSciences, Inc., today announced that it has been awarded over $3 million across four government grants.

These grants were each awarded to Precision during the 4th Quarter of 2010 and came from the National Institute of Standards and Technology, the Treasury Department, the National Institute of Health, and the State of North Carolina. Together, the grant funding will allow Precision to accelerate development of its proprietary genome engineering technology called the Directed Nuclease Editor (DNE).

“Precision is poised to utilize DNE technology to address major challenges facing the biomanufacturing industry,” said Michael Nicholson, Director of Cell Biology at Precision BioSciences. “These grants will enable us to further refine applications of the technology, particularly as it pertains to cell line engineering.”

“We are thrilled to see that so many government funding agencies are recognizing the potential

of our DNE technology,” stated Derek Jantz, VP of Scientific Development at Precision, “we are grateful to all of those involved in making these awards to Precision.”

About Precision BioSciences

Precision’s mission is to utilize its engineered endonuclease technology to become the world

leader in the field of genomic molecular biology. Precision’s proprietary Directed Nuclease

EditorTM (DNE) technology enables the production of custom genome editing enzymes that can

insert, remove, modify, and regulate essentially any gene in mammalian or plant cells.

Precision BioSciences has already produced hundreds of custom endonucleases for partners and

internal development that can precisely alter naturally occurring sequences within genomes.

Precision has successfully partnered its DNE technology with several of the world’s largest

agbiotech firms and is internally developing applications in biological production and human

therapeutics. For additional information, please visit www.precisionbiosciences.com.
