Forward-Looking Statements

This press release contains "forward-looking information" and "forward-looking statements" (collectively, "forward-looking information") within the meaning of applicable securities laws. Such forward-looking information or statements ("FLS") are provided for the purpose of providing information about management's current expectations and plans relating to the future. Readers are cautioned that reliance on such information may not be appropriate for other purposes. Any such FLS may be identified by words such as "proposed", "expects", "intends", "may", "will", and similar expressions. FLS contained or referred to in this press release includes, but is not limited to, statements regarding the proposed timing and various steps contemplated in respect of the Transaction or the Acquisition, the combination of the Cook ART and Hamilton Thorne operations, and the likelihood that the Transaction and the Acquisition will be consummated.

FLS is based on a number of factors and assumptions which have been used to develop such statements and information, but which may prove to be incorrect. Although the Company believes that the expectations reflected in such FLS are reasonable, undue reliance should not be placed on FLS because the Company can give no assurance that such expectations will prove to be correct. Factors that could cause actual results to differ materially from those described in such FLS include, without limitation, the following factors, many of which are beyond the Company's control and the effects of which can be difficult to predict: (a) the possibility that the Transaction will not be completed on the terms and conditions, or on the timing, currently contemplated, and that it may not be completed at all, due to a failure to obtain or satisfy, in a timely manner or otherwise, required shareholder, court and the Required Regulatory Approvals and other conditions of closing necessary to complete the Transaction or for other reasons; (b) the possibility of adverse reactions or changes in business relationships resulting from the announcement or completion of the Transaction or the Acquisition; (c) risks relating to the abilities of the parties to satisfy conditions precedent to the Transaction and the Acquisition; (d) credit, market, currency, operational, liquidity and funding risks generally and relating specifically to the Transaction and the Acquisition, including changes in economic conditions, interest rates or tax rates; (e) risks related to the Company resulting from the combination of the Company and the Cook ART operations in retaining existing customers and attracting new customers, retaining key personnel, executing on growth strategies, advancing its product line and protecting its intellectual property rights and proprietary information; (f) changes and trends in the Company's industry and the global economy; and (g) the identified risk factors included in the Company's public disclosure, including the annual information form dated March 27, 2024, which is available on SEDAR+ at www.sedarplus.ca. If any of these risks or uncertainties materialize, or if the assumptions underlying the FLS prove incorrect, actual results or future events might vary materially from those anticipated in the FLS. Although the Company has attempted to identify important risk factors that could cause actual results to differ materially from those contained in FLS, there may be other risk factors not presently known to the Company or that the Company presently believes are not material that could also cause actual results or future events to differ materially from those expressed in such FLS. The FLS in this press release reflect the current expectations, assumptions, judgements and/or beliefs of the Company based on information currently available to the Company and are subject to change without notice.

Any FLS speaks only as of the date on which it is made and, except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any FLS, whether as a result of new information, future events or results or otherwise, except as required under applicable securities laws. The FLS contained in this press release are expressly qualified by this cautionary statement.
