Ion Torrent Extends Ion Personal Genome Machine Sequencer Grant Program in Europe

GUILFORD, Connecticut, September 15, 2010 - Ion Torrent today announced that the deadline for the Ion Personal Genome
Machine (PGM(TM)) Sequencer Grant Program in Europe has been extended to Nov.
22 to give more scientists the opportunity to win a DNA sequencer for their
own labs.

To apply, researchers need only write a few hundred words describing
their proposed experiment. The two scientists whose proposals best take
advantage of the Ion PGM sequencer's speed, throughput and low cost will each
be awarded a sequencer in the first quarter of 2011. To apply, go to
www.iontorrent.com/grant-program/

As part of their grants, the winning scientists will also receive a
perpetual license to the DNASTAR(R) SeqMan NGen assembly software and the CLC
bio Genomics Workbench bioinformatics software.

The Ion PGM Sequencer Grant Program is designed to foster the development
of new applications for DNA sequencing that leverage the instrument's
unprecedented speed, scalability and low cost. The Ion PGM sequencer can do a
run in an hour or two, and costs one-tenth the price of other sequencers to
buy and to run. Priority is given to projects that result in an ongoing
application that takes advantage of the Ion PGM sequencer's speed, ease of
use, small footprint and low cost per run. The applicants' goal should be to
address a problem that was intractable using previous technologies.

"Ion Torrent has developed the world's first semiconductor-based DNA
sequencing technology, directly translating chemical information into digital
data," said Dr. Jonathan Rothberg, founder, chairman and CEO of Ion Torrent.
"DNA sequencing is performed with all natural nucleotides on Ion's
proprietary semiconductor chips, leveraging a billion years of evolution and
a trillion dollars of investment to allow unprecedented scalability, speed,
and costs according to Moore's Law. I encourage every scientist in Europe who
has a research project that they've always dreamed of doing, but haven't had
the means to pursue, to send us a proposal."

Two grants will be awarded to European scientists under the program. The
Dr. James Watson Healthcare Grant will be awarded to the outstanding proposal
that addresses human health, in recognition of Dr. Watson's interest in
healthcare issues. The Dr. Gordon Moore Environment Grant will be awarded to
the outstanding proposal that addresses environmental, ecological or
evolutionary issues, areas of study that the Gordon and Betty Moore
Foundation have long supported.

The grant submissions will be judged on the merit of their ideas. The
judges for the competition are Dr. Rothberg, Dr. Mathias Uhlen, Dr. George
Church and the Dr. Svante Paabo laboratory.

About Ion Torrent

Ion Torrent has developed a DNA sequencing system that directly
translates chemical signals (A, C, G, T) into digital information (0, 1) on a
semiconductor chip. The result is a sequencing system that is simpler,
faster, more cost effective and scalable than any other technology available.
Because Ion Torrent produces its proprietary semiconductor chips in standard
CMOS factories, it can leverage the US$1 trillion investment that has been
made in the semiconductor industry over the past 40 years. As a result, Ion
Torrent directly benefits from four decades of exponential improvement in
semiconductor technology, also known as Moore's Law.

Ion Torrent was founded in August 2007 by Dr. Jonathan Rothberg, a
pioneer of high-speed, massively parallel DNA sequencing. Ion Torrent is
based in Guilford, Conn., with offices in San Francisco. Ion Torrent will
launch the Ion Personal Genome Machine sequencer in 2010. For more
