These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by the Company and its management, and OpSec and its management, as the case may be, are inherently uncertain. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties.

generally; (9) risks relating to the growth of OpSec’s business and its ability to realize expected results; (10) risks relating to OpSec’s plans for targeted acquisitions and upscaling organically; (11) risks relating to the growth and expansion of OpSec’s portfolio of solutions; (12) risks relating to the viability of OpSec’s growth strategy, including related capabilities; (13) risks relating to trends and developments in the IP/brand optimization, monetization and protection industry; (14) the risk that the combined company may be adversely affect by other economic, business, and/or competitive factors, or adverse macroeconomic conditions, including inflation, supply chain delays and increasing interest rates; (15) variances between the historical financial information OpSec presents and its PCAOB audited financial statements for 2022 which may be significant when they become available; and (16) other risks and uncertainties, including those identified in any proxy statement/prospectus in a Registration Statement on Form F-4 relating to the Transactions (which is expected to be filed by Pubco with the SEC), the “Risk Factors” section of the Company’s registration statement on Form S-1, other documents filed by the Company from time to time with the SEC and any risk factors made available to you in connection with Pubco, the Company, OpSec and the Transactions.

The foregoing list of factors is not exclusive.

All subsequent written and oral forward-looking statements concerning the Company, OpSec or Pubco, the Transactions described herein or other matters attributable to the Company, OpSec, Pubco or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Each of the Company, OpSec and Pubco expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in their expectations with respect thereto or any change in events, conditions or circumstances on which any statement is based.
