Mr. Wedell-Wedellsborg disclaims beneficial ownership over the shares held by WG Biotech ApS for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Act”), and this Schedule 13G shall not be deemed an admission that Mr. Wedell-Wedellsborg is the beneficial owner of such shares for Section 13(d) of the Act or any other purpose.
