      CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS
       
      This Specialized Disclosure Report on Form SD and the Conflict Minerals Report filed as an exhibit hereto may contain so-called “forward-looking statements,” all of which are based on management’s
        current expectations and are subject to risks and uncertainties which may cause results to differ materially from those set forth in the statements. One can identify these forward-looking statements by their use of words such as “anticipates,”
        “expects,” “plans,” “will,” “estimates,” “forecasts,” “projects” and other words of similar meaning. One can also identify them by the fact that they do not relate strictly to historical or current facts. Forward-looking statements include, for
        example, statements about our expectations, intentions and plans to improve our due diligence and risk mitigation strategies related to any Conflict Minerals used in our manufacture or contract to manufacture activities. One must carefully consider
        any such statement and should understand that many factors could cause actual results to differ materially from the Company’s forward-looking statements. These factors include inaccurate assumptions and a broad variety of other risks and
        uncertainties, including some that are known and some that are not. No forward-looking statement can be guaranteed and actual future results may vary materially.
       
      
      
      The Company does not assume the obligation to update any forward-looking statement. One should carefully evaluate such statements in light of factors, including risk factors, described in the
        Company’s filings with the Securities and Exchange Commission, especially on Forms 10-K, 10-Q and 8-K. In Item 1A, “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed on February 24, 2023, the
        Company discusses in more detail various important risk factors that could cause actual results to differ from expected or historic results. The Company notes these factors for investors as permitted by the Private Securities Litigation Reform Act
        of 1995. One should understand that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete statement of all potential risks or uncertainties.
