(1) NATURE OF OPERATIONS AND BUSINESS RISKS

The accompanying consolidated financial statements reflect the results of operations of Raptor Pharmaceutical Corp. (the "Company" or "Raptor") and have been prepared in accordance with the accounting principles generally accepted in the United States of America ("GAAP"). The Company's fiscal year end is August 31.

On July 28, 2009, the Company and ECP Acquisition, Inc., a Delaware corporation, the Company's then wholly-owned subsidiary, entered into an Agreement and Plan of Merger and Reorganization (the "2009 Merger Agreement"), with Raptor Pharmaceuticals Corp., a Delaware corporation ("RPC"). On September 29, 2009, on the terms and subject to the conditions set forth in the 2009 Merger Agreement, pursuant to a stock-for-stock reverse triangular merger (the "2009 Merger"), ECP Acquisition, Inc. was merged with and into RPC and RPC survived the 2009 Merger as a wholly-owned subsidiary of the Company. Immediately prior to the 2009 Merger and in connection therewith, the Company effected a 1-for-17 reverse stock split of its common stock and changed its corporate name from "TorreyPines Therapeutics, Inc." to "Raptor Pharmaceutical Corp."

As a result of the 2009 Merger and in accordance with the 2009 Merger Agreement, each share of RPC's common stock outstanding immediately prior to the effective time of the 2009 Merger was converted into the right to receive 0.2331234 shares of the Company's common stock, on a post 1-for-17 reverse-split basis. Each option and warrant to purchase RPC's common stock outstanding immediately prior to the effective time of the 2009 Merger was assumed by the Company at the effective time of the 2009 Merger, with each share of such common stock underlying such options and warrants being converted into the right to receive 0.2331234 shares of the Company's common stock, on a post 1-for-17 reverse split basis, rounded down to the nearest whole share of the Company's common stock. Following the 2009 Merger, each such option or warrant has an exercise price per share of the Company's common stock equal to the quotient obtained by dividing the per share exercise price of such common stock subject to such option or warrant by 0.2331234, rounded up to the nearest whole cent.

Immediately following the effective time of the 2009 Merger, RPC's stockholders (as of immediately prior to the 2009 Merger) owned approximately 95% of the Company's outstanding common stock and the Company's stockholders (as of immediately prior to the 2009 Merger) owned approximately 5% of the Company's outstanding common stock.

RPC, the Company's wholly-owned subsidiary, was the "accounting acquirer," and for accounting purposes, the Company was deemed as having been "acquired" in the 2009 Merger. The board of directors and officers that managed and operated RPC immediately prior to the effective time of the 2009 Merger became the Company's board of directors and officers. Additionally, following the effective time of the 2009 Merger, the business conducted by RPC immediately prior to the effective time of the 2009 Merger became primarily the business conducted by the Company. In December 2011, RPC merged into Raptor Pharmaceutical Corp.

Raptor, a publicly-traded biotechnology company, seeks to research, manufacture, and commercialize medicines that improve life for patients with severe, rare disorders. Raptor currently has product candidates in pre-commercial and clinical development designed to potentially treat nephropathic cystinosis, Non-alcoholic Steatohepatitis ("NASH"), Huntington's Disease ("HD") and aldehyde dehydrogenase deficiency ("ALDH2"). Raptor's preclinical programs are based upon bioengineered novel drug candidates and drug-targeting platforms derived from the human receptor-associated protein and related proteins that are designed to target cancer and infectious diseases.

The Company is subject to a number of risks, including: the need to raise capital through equity and/or debt financings; the uncertainty whether the Company's research and development efforts will result in successful commercial products; competition from larger organizations; reliance on licensing the proprietary technology of others; dependence on key personnel; uncertain patent protection; and dependence on corporate partners and collaborators.
