***Forward-Looking Statements***

Certain statements included in this Current Report on Form 8-K ("***Current Report***") and exhibit hereto that are not historical facts are forward-looking statements. Forward-looking statements generally are accompanied by words such as "expect", "expected" and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding expectations relating to the business combination, including the proceeds of the business combination and the financing and the timing of the closing of the business combination. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of BBOT's and Helix's management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by an investor as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions. Many actual events and circumstances are beyond the control of BBOT and Helix. Some important factors that could cause actual results to differ materially from those in any forward-looking statements could include: changes in domestic and foreign business, market, financial, political and legal conditions; the ability of the parties to successfully consummate the business combination; the ability to satisfy the conditions to the consummation of the Business Combination, including the satisfaction of the minimum cash condition; the ability of the combined company to meet Nasdaq's initial listing standards and list the combined company's stock on Nasdaq; and the risks set forth in the definitive proxy statement/prospectus filed by Helix with the Securities and Exchange Commission on July 10, 2025 (File No. 333-288222), as supplemented on July 21, 2025, including the "Risk Factors" section therein, and Helix's other filings with the Securities and Exchange Commission. If any of these risks materialize or Helix's or BBOT's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Helix or BBOT presently know or that Helix and BBOT currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Helix's and BBOT's expectations, plans, or forecasts of future events and views as of the date of this Current Report and are qualified in their entirety by reference to the cautionary statements herein. Helix and BBOT anticipate that subsequent events and developments will cause Helix's and BBOT's assessments to change. These forward-looking statements should not be relied upon as representing Helix's and BBOT's assessments as of any date subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither Helix, BBOT, nor any of their respective affiliates undertake any obligation to update these forward-looking statements, except as required by law.
