SECTION 16
POWER OF ATTORNEY

I, Thomas Bostick, do hereby constitute
and appoint Donald P. Lehr and Rick L.
Sterling, my true and lawful attorneys-in-fact,
either of whom acting singly is hereby authorized,
for me and in my name and on my behalf as a
director, officer and/or shareholder of INTREXON
CORPORATION to (i) prepare, execute in my name
and on my behalf, and submit to the U.S. Securities
and Exchange Commission (the SEC) a Form ID,
including any necessary amendments thereto, and
any other documents necessary or appropriate to
obtain codes and passwords enabling me to make
electronic filings with the SEC of reports required
by Section 16(a) of the Securities Exchange Act of
1934 or any rule or regulation of the SEC in respect
thereof; and (ii) prepare, execute and file any and
all forms, instruments or documents, including any
necessary amendments thereto, as such attorneys or
attorney deems necessary or advisable to enable me to
comply with Section 16 of the Securities Exchange Act of
1934 or any rule or regulation of the SEC in respect thereof
(collectively, Section 16).

I do hereby ratify and confirm all acts my said attorney
shall do or cause to be done by virtue hereof.  I acknowledge
that the foregoing attorneys-in-fact, serving in such capacity
at my request, are not assuming, nor is INTREXON CORPORATION
assuming, any of my responsibilities to comply with Section 16.

This power of attorney shall remain in full force and effect
until it is revoked by the undersigned in a signed writing
delivered to each such attorney-in-fact or the undersigned
is no longer required to comply with Section 16, whichever
occurs first.

WITNESS the execution hereof this 30th day of November, 2017.
