Important Notice Regarding Forward-Looking Statements

This Current Report on Form 8-K contains certain “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 with respect to the proposed Business Combination. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result” and similar expressions, but the absence of these words does not mean that a statement is not forward-looking. Such statements include, but are not limited to, statements regarding the proposed Business Combination, including the anticipated initial enterprise value, the benefits of the proposed Business Combination, integration plans, anticipated future financial and operating performance and results, including estimates for growth, and the expected timing of the Business Combination. The words “expect,” “believe,” “estimate,” “intend,” “plan” and similar expressions indicate forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to various risks and uncertainties, assumptions (including assumptions about general economic, market, industry and operational factors), known or unknown, which could cause the actual results to vary materially from those indicated or anticipated. Consequently, you should not rely on these forward-looking statements as predictions of future events.

Many factors could cause actual future events to differ materially from the forward-looking statements in this Current Report, including but are not limited to: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of YHN’s securities; (ii) the failure to satisfy the conditions to the consummation of the Business Combination, including the approval of the Business Combination Agreement by the shareholders of YHN; (iii) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement; (iv) the outcome of any legal proceedings that may be instituted against any of the parties to the Business Combination Agreement following the announcement of the entry into the Business Combination Agreement and proposed Business Combination; (v) the ability of the parties to recognize the benefits of the Business Combination Agreement and the proposed Business Combination; (vi) the lack of useful financial information for an accurate estimate of future capital expenditures and future revenue; (vii) statements regarding Mingde’s industry and market size; (viii) financial condition and performance of Mingde, including the anticipated benefits, the implied enterprise value, the expected financial impacts of the Business Combination, potential level of redemptions of YHN’s public shareholders, the financial condition, liquidity, results of operations, the products, the expected future performance and market opportunities of Mingde; (ix) the impact from future regulatory, judicial, and legislative changes in Mingde’s industry; (x) competition from larger companies that have greater resources, technology, relationships and/or expertise; and (xi) those factors discussed in YHN’s filings with the SEC and that will be contained in the definitive proxy statement/prospectus relating to the Business Combination. You should carefully consider the foregoing factors and the other risks and uncertainties that will be described in the “Risk Factors” section of the definitive proxy statement/prospectus and other documents to be filed by YHN from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and while Mingde and YHN may elect to update these forward-looking statements at some point in the future, they assume no obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, subject to applicable law. Neither Mingde nor YHN gives any assurance that Mingde, or YHN, or the combined company, will achieve its expectations.
