 Forward-Looking Statements

  

 This Current Report on the Form 8-K includes
“forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private
Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,”
“plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,”
“believe,” “seek,” “target” or other similar expressions that predict or indicate future events or
trends or that are not statements of historical matters. These forward-looking statements also include, but are not limited to, statements
regarding estimation of the listing. These statements are based on various assumptions, whether or not identified in this press release,
and on the current expectations of MLAC’s management and are not predictions of actual performance. These statements involve risks,
uncertainties and other factors that may cause the actual results, levels of activity, performance, or achievements to be materially
different from those expressed or implied by these forward-looking statements. Although MLAC believes that it has a reasonable basis
for each forward-looking statement contained in this press release, MLAC cautions you that these statements are based on a combination
of facts and factors currently known and projections of the future, which are inherently uncertain. The forward-looking statements in
this press release represent the views of MLAC as of the date of this press release. Subsequent events and developments may cause those
views to change. Except as may be required by law, MLAC does not undertake any duty to update these forward-looking statements.
