Industry and Market Data · In this presentation, the Company relies on and refers to information and statistics regarding market participants in the sectors in which the Company competes and other industry data. The Company obtained this information and statistics from third - party sources, including reports by market research firms and company filings, but have not independently verified such information. Trademarks · This presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SM © or ® symbols, but the Company will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. Financial Information · Unless otherwise specified, the financial information and data contained in this presentation is unaudited, is based on draft statutory accounts, does not conform to Regulation S - X, and is subject to PCAOB audit, with respect to yearly data, and subject to auditor review, with respect to quarterly data. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in any registration statement that may be filed with the SEC with respect to the Transaction and the proxy statement/prospectus contained therein and / or may differ materially from the Company’s actual results contained in any such registration statement. You should review the Company's audited financial statements, which will be included in any registration statement that may be filed with the SEC with respect to the Transaction and the proxy statement/prospectus contained therein. In addition, all of the Company's historical financial information included herein is preliminary and subject to change. Use of Non - GAAP Financial Measures · This presentation includes non - GAAP financial measures, including EBITDA. EBITDA is defined as net income (loss), adjusted to exclude: (i) finance costs, (ii) income tax expense, (iii) impairment losses, (iii) depreciation and amortization, and (iv) net foreign exchange gains/losses. · The Company believes that these non - GAAP measures are useful to investors for two principal reasons: 1) these measures may assist investors in comparing performance over various reporting periods on a consistent basis by removing from operating results the impact of items that do not reflect core operating performance; and 2) these measures are used by the Company’s management and board of directors to assess its performance and may (subject to the limitations described below) enable investors to compare the performance of the Company to its competition. The Company believes that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. These non - GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. Other companies may calculate these non - GAAP measures differently, and therefore such measures may not be directly comparable to similarly titled measures of other companies. / Disclaimer 3

/ CCT ® for Lithium CCT ® for Lithium - Ion Battery Platform 18 Overview - CCT ® has been determined to benefit the performance of lithium - ion batteries. - Initial optimization work focuses on LFP lithium - ion batteries. - CCT ® and the patents describe a method on how to increase cycle life and reduce capacity loss of batteries that in essence works for any battery chemistry . When certain important parameters of the battery chemistry in question are known, WaveTech can in theory adapt the CCT ® - method(s) accordingly . - WaveTech have so far been successful with lead acid batteries and is targeting lithium - ion batteries next . Expected results are increased charge acceptance, increased constant capacity level during cycling, increased cycle life and shortened charge time . Test and Feasibility Study - The feasibility study has been concluded, confirming WaveTech’s expectation in that similar, or comparable, results to those of CCT ® applied on lead acid batteries, can be achieved on lithium - ion batteries. - The first CCT ® prototype for lithium batteries is in place (first model). - WaveTech expects to install the equipment needed to build its own lithium - ion cells/batteries to facilitate the entire process to market. The Technology - WaveTech conduct its lithium - ion research and development (“R&D”) in two ways: improving the batteries “from the outside” and improving it “from the inside.” - Validation testing of CCT ® for lithium batteries has followed the same methodology as with lead acid batteries, initially by mounting a CCT ® unit on the outside of 12V lithium batteries (retro - fit). - WaveTech also wants to apply CCT ® to lithium batteries from within the interior of the cells, to optimize the materials there. Allowing WaveTech to optimize existing chemistries or design new lithium - ion cells, producing even better results.
