From the Tonaquint SPA PR...
" Additionally, the issuance of the Shares will not be registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Tonaquint's representations as expressed in the Stock Purchase Agreement (SPA).
Under the SPA, Tonaquint shares are characterized as "restricted securities" under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Tonaquint must hold the Shares indefinitely unless subsequently registered for resale with the Securities and Exchange Commission."
