EXPLANATORY NOTE

This Amendment No. 3 to Schedule 13G (this “Amendment”) is being filed to amend and supplement Amendment No. 2 to the Schedule 13G filed with the Securities and Exchange Commission on February 16, 2016 (the “Prior Schedule 13G”). This Amendment clarifies who the reporting persons are in connection with the Prior Schedule 13G, as the sole reporting person is Credit Suisse Trust Limited in its capacity as the trustee of The Mandalay Trust, as more fully described below. The Prior Schedule 13G incorrectly identified the other members of the potential group, as described below, as filing a joint filing with Credit Suisse Trust Limited. The Prior Schedule 13G has been revised solely to reflect Credit Suisse Trust Limited as the sole reporting person and has not been updated to reflect any information or holdings as of a more current date, and shall remain in full force and effect.

Meadowsweet Assets Limited (the “Record Holder”) beneficially owns 4,364,286 shares of common stock of Raptor Pharmaceutical Corporation (the “Issuer”). Record Holder is wholly owned by The Mandalay Trust (the “Trust”), of which Credit Suisse Trust Limited (the “Trustee”) acts as the trustee. Bidzina Ivanishvili is the settlor of the Trust. George Bachiashvili is an investment manager of the Trust. Bidzina Ivanishvili, George Bachiashvili, the Record Holder, the Trust and the Trustee in its capacity as trustee for the Trust may be deemed to be a group for the shares of common stock of the Issuer as defined in Rule 13d-5(b) under the Securities Exchange Act of 1934, as amended, and each member of such group may be deemed to beneficially own the ordinary shares beneficially owned by other members constituting such group. The Trustee disclaims beneficial ownership of the ordinary shares. The filing of this Schedule 13G should not be deemed an admission that the Trustee is the beneficial owner of such ordinary shares for any purpose.
