Intrexon to Acquire 48% Stake in AquaBounty Technologies

Utilizing Biotechnology to Improve Productivity in Aquaculture

BLACKSBURG, Va., Oct. 31, 2012 (GLOBE NEWSWIRE) -- Intrexon Corporation, a
synthetic biology company that utilizes its proprietary technologies to
provide control over cellular function, today announced that it has entered
into a definitive purchase agreement to acquire an approximately 48% interest
in AquaBounty Technologies, Inc. (LSE:ABTX), a biotechnology company focused
on enhancing the productivity in aquaculture, from existing shareholders.
Pursuant to the purchase agreement, Intrexon will purchase 48,631,444 shares
from Linnaeus Capital Partners B.V. and its affiliate, Tethys Ocean B.V., for
$6 million (US) in cash, or approximately $0.123 per share in cash, which is
equivalent to approximately £0.0764 per share[1]. This represents a premium of
approximately 49% to the mid-market closing price of AquaBounty's common stock
on the date immediately preceding this announcement. Upon the closing of the
sale, the founder of Linnaeus Capital, Kakha Bendukidze and three other
directors nominated by Linnaeus Capital will resign their seats on
AquaBounty's board of directors.

In accordance with provisions of AquaBounty's charter, following the close of
the transaction Intrexon is required to commence a tender offer for any and
all of the other outstanding shares of AquaBounty. Intrexon's tender only will
be conditional on receiving acceptances in respect of shares which, together
with the shares acquired from Tethys Ocean and Linnaeus, will result in
Intrexon Corporation holding shares representing more than 50% of the
remaining outstanding shares in AquaBounty. The offer price per share in the
tender will be equal to the per share price paid by Intrexon in its
acquisition of shares from Linnaeus Capital and Tethys Ocean. Further details
on the tender will be provided following the close of the acquisition of
shares pursuant to the purchase agreement.

Thomas Kasser, President of Intrexon's Animal Science Division, stated, "This
transaction will accelerate our efforts to play a leading role in solving the
world's emerging food shortages through biotechnology. AquaBounty's pioneering
work in genetically modified fish is an initial step toward creating a
large-scale, efficient and environmentally safe and sustainable global
aquaculture market. We look forward to working with the AquaBounty team to
improve aquaculture productivity and expand the reach of their molecular
modification technology."

As a condition to executing the definitive agreement with Linnaeus Capital,
Intrexon and AquaBounty executed an agreement restricting AquaBounty's ability
to issue additional securities prior to, and during, the tender offer, and
certain other provisions. Intrexon and AquaBounty expect to negotiate and
execute, prior to the closing of the stock acquisition, a relationship
agreement containing provisions consistent with the rights of a significant
holder of an AIM listed company.
