CAUTIONARY NOTE REGARDING FORWARD-LOOKING INFORMATION

Aduro cautions readers regarding forward-looking statements found in this document and in any other statement made by, or on the behalf of the Company. Statements contained in this AIF that are not historical facts are "forward-looking information" or "forward-looking statements" (collectively, "Forward-Looking Information") within the meaning of applicable Canadian securities laws.

Forward-Looking Information includes, but is not limited to, disclosure regarding possible events, conditions or financial performance that is based on estimates and assumptions about future economic conditions and courses of action. The words "believes", "expects", "intends", "projects" and "anticipates", and other similar expressions, commonly identify such Forward-Looking Information.

Forward-Looking Information involves 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, performance or achievements expressed or implied by the Forward-Looking Information. In this AIF, Forward-Looking Information includes, but is not limited to, the Company's limited operating history upon which an evaluation of the Company and its prospects can be based; the Company's ability to generate profits; the Company's ability to manage growth; the adverse effect of competitors on the Company's operation, strategies and profitability; the Company's ability to successfully develop, protect and commercialize its technology; the environmental impact of the Company's technology and its ability to reduce waste; the HCT's higher performance with lower energy consumption, resulting in a greener approach compared to conventional methods and technology; the Company's belief that the HCT process is expected to have a lower environmental footprint, produce higher yields at higher quality, and generate fewer harmful by-products; the HCT's ability to be applied to various feedstocks, allowing for efficient processing of different materials and minimizing environmental impact; the ability of the Company's technology to reduce the environmental impact associated with petroleum production and processing, landfilling, waste incineration, and gasification; the expectation that HCT will reduce the production of new plastics from petroleum by increasing the recycling rate of waste plastics into oils; the operational risks against which the Company may not be insured against or for which insurance is not available; the impact of negative cash flows on the Company's operations and how, if the Company is unable to obtain further financing, the Company's business operations may fail; the impact of strong market fluctuation that can negatively affect the pricing of commodities such as biofuels or crude oils; the impact of government regulations that can negatively affect economic justifications and or models; other risks described in this AIF and described from time to time in the Company's documents filed with Canadian securities regulatory authorities; and the impact of COVID-19 or any other potential future pandemics or disease outbreaks on the Company's ability to raise capital, successfully develop, and commercialize its technology.

Accordingly, readers should not place undue reliance on Forward-Looking Information. Except as required by law, the Company does not assume any obligation to release publicly any revisions to Forward-Looking Information contained in this AIF to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. The Forward-Looking Information in this AIF is based on management's beliefs, estimates and opinions and is given only as of the date of this AIF, and is subject to a variety of risks, uncertainties and other factors that could cause actual events or results to differ materially from those anticipated in the Forward-Looking Information. Persons reading this AIF are cautioned that statements containing Forward-Looking Information are only predictions, and that the Company's actual future results or performance are subject to certain risks and uncertainties. Material risks related to the Company's HCT that could cause actual events or results to differ materially from those anticipated in the Forward-Looking Information include, but are not limited to, the following: the actual performance and energy efficiency of the HCT process may not meet expectations, leading to higher operational costs and lower environmental benefits; the adoption of HCT technology by industry stakeholders may be slower than anticipated, affecting the Company's ability to achieve projected environmental benefits; changes in environmental regulations could impact the feasibility and cost-effectiveness of the HCT process; potential issues in scaling up the technology for commercial use, including technical failures and supply chain disruptions; the emergence of new technologies or improvements in existing methods could reduce the competitive advantage of HCT; and fluctuations in market conditions, such as the price of raw materials and energy, could affect the cost savings and environmental impact of the HCT process. See additional risk factors that may cause actual events or results to differ materially from those anticipated in the Forward-Looking Information under the heading "Risk Factors" in this AIF.

The material factors and assumptions used by the Company's management to develop the Forward-Looking Information include, but are not limited to, the following: the Company's ability to obtain any necessary financing on acceptable terms; the timing and amount of capital expenditures; the retention of skilled personnel; the extensive research by the Company on HCT through numerous controlled technology evaluation sessions and the data and reports obtained from such technology evaluation sessions; the timely receipt of any required regulatory approvals; the continuation of current tax and regulatory regime; the current exchange rate and interest rates; and general economic and financial market conditions. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

The Forward-Looking Information contained in this AIF is expressly qualified by this cautionary statement. Readers are cautioned not to place undue reliance on Forward-Looking Information.
