2. Forward Looking Statements
This presentation contains forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of words such as
“plans”, “expects” or “does not expect”, “is expected”, “estimates”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such
words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved. Forward-
looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements
of IWS to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.
Examples of such statements include discussions with respect to the future prospects of IWS’s business and the intention to grow the business and
operations of IWS. Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-
looking statements contained in this presentation and IWS’s preliminary short form prospectus. Such forward-looking statements are based on a number
of assumptions which may prove to be incorrect, the ability of IWS to obtain necessary financing, general economic conditions, consumer interest in the
services and products of IWS, competition, and anticipated and unanticipated costs. Such statements could also be materially affected by the impact of
general imprecision of taxation policies, competition, the lack of available and qualified personnel or management, stock market volatility and the ability
to access sufficient capital from internal or external sources. Actual results, performance or achievement could differ materially from those expressed
herein. While IWS anticipates that subsequent events and developments may cause its views to change, IWS, except as required by law, specifically
disclaims any obligation to update these forward-looking statements. These forward-looking statements should not be relied upon as representing IWS’s
views as of any date subsequent to the date of this presentation. Although IWS has attempted to identify important factors that could cause actual
actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events
or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as
actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance
on forward-looking statements. The factors identified above are not intended to represent a complete list of the factors that could affect IWS.

5. How it Works - SHARC
1. Wastewater which is typically ~21˚C (70˚F),
(heated from showers, dishwashers, washing
machines etc.) is captured before leaving a
facility in an on site tank. Or directly pulled
from a city sewer main.
2. Solids are separated from the waste stream
with IWS patented technology and the warm
water is passed through a heat exchanger,
which transfers thermal energy from the
contaminated water to a process loop.
3. Used in combination with water sourced heat
pumps IWS systems can heat incoming water,
and provide space heating and cooling at
high efficiencies (400-500%).
4. Solids and contaminated water are released
to the sewer system.

Scottish Water - £20 M Initial Pipeline
Strategic Alliance with Scottish Water to develop SHARC Systems
across Scotland
 Scottish Water Horizons has estimated that up to 750 SHARC systems would need to be
installed by 2020 to enable Scotland to achieve its carbon savings targets.
 The result of 2 years of informal collaboration between SHARC Energy Systems and Scottish
Water Horizons, which has created a £20 million (CAN$32.4 million) pipeline of potential
installations across Scotland when deployed would generate 170 GWHs per year of heating
and cooling to displace the fossil fuel currently used.

Partnership with Metro Vancouver
Background:
 Metro Vancouver (MV) - partnership of 21 municipalities, one Electoral Area and one Treaty First
Nation that collaboratively plans for and delivers regional-scale services across the lower mainland
of BC.
 MV core services are drinking water, wastewater treatment and solid waste management.
 Completed an inaugural project at The South East False Creek Neighborhood Energy Utility, a large
wastewater heat recovery project supplying a District Heating Network. The NEU provides space
heating and hot water for 4,300,000 square feet (395,000 m2) of residential, commercial, and
institutional space
 Marks the first installation of the newest and largest SHARC wastewater heat recovery system, the model
880.
 The SHARC 880 handles a flow rate capacity increase of three-times when compared to existing SHARC
models
 Expansion plans in place to serve new developments in the neighborhood including the Great
Northern Way campus lands, a university campus jointly owned by the University of British
Columbia, Simon Fraser University, British Columbia Institute of Technology and Emily Carr
University.

21. Background:
 Upcoming projects with The British Columbia Housing Management Commission (BC Housing) a crown
corporation in the province of British Columbia.
 BC Housing works in partnership with approximately 800 housing providers - mostly non-profit and
housing co-operatives - over 98,000 households in 200 communities across the province. Following a
