LEGAL NOTICE REGARDING FORWARD-LOOKING STATEMENTS

This report contains "forward-looking statements" within the meaning of applicable securities laws that reflect the Company's current expectations, forecasts and assumptions. Generally, forward looking statements can be identified by the use of forward-looking terminology such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words or phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved".

Such forward looking statements involve a number of known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results expressed or implied by such forward looking statements.

These include but are not limited to the economic condition of the railroad industry, which is affected by numerous factors beyond the Company's control including slow sales cycles, creation and adoption of new technologies, the existence of present and possible government regulation and competition. Although Kelso Technologies Inc. ("Kelso" or the "Company") believes the Company's anticipated future results, performance or achievements expressed or implied by the forward-looking statements are based upon reasonable assumptions and expectations, they can give no assurance that such expectations will prove to be correct. The reader should not place undue reliance on forward-looking statements as such statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Kelso to differ materially from anticipated future results, performance or achievement expressed or implied by such forward-looking statements.

Such risks and uncertainties include, without limitation; the risk that the Company's products may not work as well as expected; the Company may not be able to break in to new markets because such markets are served by strong and embedded competitors or because of long-term supply contracts; the Company may not be able to grow and sustain anticipated revenue streams; the Company may have underestimated the cost of product development and the time it takes to bring products to market; the Company may not be able to finance the Company's intended product development; that Management may not be able to continue to initiate new product strategies to secure a more reliable growth of financial performance in the future; the Company's products may not sell as well as expected, and competitors may offer better or cheaper alternatives to the Company's products; the Company's technologies may not be patentable, and if patents are granted, the Company may not be able to protect the Company's investment in intellectual property if the Company's patents are challenged; the Company's intended technologies may infringe on the intellectual property of other parties; the Company may not have any parties interested in licensing the Company's technology as expected and certain other risks detailed from time-to-time in Kelso's public disclosure documents.

Although the Company has attempted to identify important risk factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that could cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements.

Accordingly, readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statements were made. Readers are advised to consider such forward-looking statements the risks set forth in the Risks and Uncertainties section of the MD&A in the current Annual Report. The Company does not undertake to update any forward-looking statements that are incorporated by reference herein, except in accordance with applicable securities laws.
