System to Treat 75,000 BPD Offshore

MONTREAL, QUEBEC – May 17, 2010 - ProSep Inc. (TSX: PRP), dedicated to providing process solutions
to the oil and gas industry, today announced that it was awarded a contract to supply a 75,000 barrel per day
(BPD) produced water treatment package for installation on an offshore facility in the South China Sea.
Delivery is expected to occur during the first quarter of 2011. For commercial reasons, no further details have
been provided.

“South East Asia has become a key growth region for ProSep,” said Jacques L. Drouin, President and CEO.
“We will continue to expand our produced water offering in this region and elsewhere, as we believe that our
water treatment expertise will be a significant driver for the Company.”

The produced water treatment package is designed using ProSep’s induced gas flotation (IGF) process, a
highly-efficient, motion-insensitive vessel ideal for space limited applications. It efficiently removes small
particles of oil contaminants from produced water, allowing oil and gas producers to meet specifications for
reinjection or regulatory requirements for overboard discharge.
