ESI Increases Private Placement to $650,000 and Announces Discussions on the Flo·Point(TM) Development Program

E. S. I. Environmental Sensors Inc. ("ESI" or the "Company") (TSX VENTURE:ESV)
is pleased to announce that, in addition to the previous announcement of a
private placement for gross proceeds of up to $350,000, the Company is now
increasing the total available under the private placement up to $650,000. It is
likely that the placement will close in tranches. The total non-brokered private
placement will now be up to 13,000,000 units ("Units") at $0.05 per Unit to
raise gross proceeds of up to CAD$650,000. Each Unit will consist of one common
share and one common share purchase warrant (a "Warrant"). Each Warrant will be
exercisable into an additional common share for a period of three years from the
closing date. The Warrants will be exercisable at a price of $0.10 for the first
year following the closing of the transaction, $0.15 for the second year
following closing, and $0.20 for the third year following closing. As mentioned
above, it is anticipated that there will be more than one closing date. 


The Private Placement is subject to TSX Venture Exchange ("Exchange")
acceptance. The proceeds from this financing will be used for general working
capital purposes. Subject to Exchange approval, the Company will pay finders'
fees in connection with the private placement. 


The Company's Flo.Point(TM) instrument was designed for the oil industry to
measure the volumetric presence of water pumped during crude oil extraction for
characterization and optimization of the production process. This technology was
deployed by ESI for approximately seven years, most recently in 2009, however,
since that time the Company has not produced any new units. Over the past months
the Company has been in discussions on the re-launch of the Flo.Point(TM)
program with a partner in the Canadian oil industry. Those discussions have now
reached a point where an agreement on a joint development program for a next
generation Flo.Point(TM) tool, known in the oil industry as a water cut sensor,
is anticipated in the coming weeks. The development program will involve
expertise based at ESI in conjunction with that of a partner in the Canadian oil
industry specializing in enhanced oil recovery, and will also include the full
co-operation of a significant lead customer in Canadian oil production. Efforts
are also under way to involve a recognized governmental research institution. In
order to succeed in launching this development program, once an agreement is in
place, the Company will need to announce a future financing.
