the prospectus dated September <FONT STYLE="font-family: Times New Roman, Times, Serif">24</FONT>, 2024 (the &ldquo;Prospectus&rdquo;),
which forms a part of our registration statement on Form F-1 (No. 333-278685). This prospectus supplement is being filed to update and
supplement the information in the Prospectus with information contained in our Current Report on Form 6-K filed with the Securities and
Exchange Commission on <FONT STYLE="font-family: Times New Roman, Times, Serif">January 2, 2025</FONT> (the &ldquo;Current Report&rdquo;).
Accordingly, we have attached the Current Report to this prospectus supplement.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">This Prospectus and prospectus supplement relate
to the resale, from time to time, by the selling shareholders named in the Prospectus (the &ldquo;Selling Shareholders&rdquo;) of an aggregate
of up to 40,000,000 of our Ordinary Shares, US$0.01 par value per Ordinary Share (the &ldquo;Ordinary Shares&rdquo;), reserved for issuance
(i) upon the conversion of currently outstanding 2.5% discount convertible promissory notes (the &ldquo;Notes&rdquo;) held by the Selling
Shareholders (the &ldquo;Conversion Shares&rdquo;), (ii) upon exercise of currently outstanding warrants (the &ldquo;Third Tranche Warrants&rdquo;)
held by the Selling Shareholders (the &ldquo;Third Tranche Warrant Shares&rdquo;), and (iii) the outstanding warrants that were issued
on January 9, 2024 (the &ldquo;Second Tranche Warrants&rdquo;, and together with the Third Tranche Warrants, the &ldquo;Warrants&rdquo;)
and held by the Selling Shareholders (the &ldquo;Second Tranche Warrant Shares&rdquo;, and together with the Third Tranche Warrant Shares,
the &ldquo;Warrant Shares&rdquo;). The Notes and Third Tranche Warrants were issued to the Selling Shareholders on March 1, 2024 (the
&ldquo;Closing Date&rdquo;). All of the Notes have been previously converted by the Selling Shareholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We registered the resale of up to an aggregate
of 40,000,000 Conversion Shares and Warrant Shares as required by the Registration Rights Agreement, dated as of July 11, 2023, as amended
(the &ldquo;Registration Rights Agreement&rdquo;), by and among us and the Selling Shareholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">To the extent that Conversion Shares and/or Warrant
Shares are issued by the Company under the terms of the Notes and Warrants, substantial amounts of Ordinary Shares could be issued and
resold, which would cause dilution and may impact the Company&rsquo;s share price. See &ldquo;Risk Factors&rdquo; and &ldquo;Convertible
Note Financing&rdquo; for additional information.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We are not selling any securities under this prospectus
and will not receive any of the proceeds from the sale of our Conversion Shares or Warrant Shares by the Selling Shareholders. However,
we may receive proceeds from the exercise of the (i) Second Tranche Warrants, which, if exercised in full for an aggregate of 3,033,159
Ordinary Shares and for cash at the current $1.65 exercise price per Ordinary Share (as repriced on December 30, 2024), would result in
gross proceeds to us of approximately $5,004,712 and (ii)Third Tranche Warrants, which, if exercised in full for an aggregate of 2,821,498
Ordinary Shares and for cash at the current $1.65 exercise price per Ordinary Share (as repriced on December 30, 2024), would result in
gross proceeds to us of approximately $4,655,471. There is no assurance that the Selling Shareholders will elect to exercise all of the
outstanding Warrants for cash and, accordingly, no assurance that we will receive the full proceeds from the exercise of the Warrants.</P>
