Amendment Description	As previously disclosed by Raptor Pharmaceutical Corp., or the “Company,” in its current report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “Commission”) on January 22, 2014, the Company has engaged Grant Thornton LLP (“Grant Thornton”) to replace Burr Pilger Mayer, Inc. (“BPM”) to serve as the Company’s independent registered public accounting firm. The Company is filing this Amendment No. 2 (the “Form 10-KT/A”) to its Transition Report on Form 10-KT for the four-month transition period ended December 31, 2012, filed with the Commission on March 14, 2013 (the “Form 10-KT”), as previously amended by Amendment No. 1 to Form 10-KT filed with the Commission on June 19, 2013, to include the audit report of Grant Thornton. In addition to the changes to the consolidated financial statements and notes thereto included in this Form 10-KT/A, which are to conform to the presentation of the 2013 financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (filed with the Commission on March 17, 2014), the Company has amended (i) Part I, Item 7 to delete its previous disclosure relating to an explanatory paragraph regarding the Company’s ability to continue as a going concern because this explanatory paragraph was removed from BPM’s reissued reports for such periods due to changes in the Company’s circumstances, (ii) Part II, Item 9A to include a reference to the attestation report of Grant Thornton and make other changes included therein, (iii) Part III, Item 14 to include the fees of Grant Thornton for re-audit of the Company’s four-month transition period ended December 31, 2012, and (iv) Part IV, Item 15 to include Grant Thornton’s consent and its reports with respect to the Company’s consolidated financial statements and internal control over financial reporting included in the Form 10-KT/A. Except as specifically noted above, this Form 10-KT/A does not modify or update disclosures in the Form 10-KT, and there have been no other material changes to the disclosures made in the Form 10-KT as of the filing of the Form 10-KT. Accordingly, except as specifically noted above, this Form 10-KT/A does not reflect events occurring after the filing of the Form 10-KT or modify or update any related or other disclosures.
