Raptor Pharmaceutical Enters Into $70 Million Financing Transaction and Amended Loan Agreement With HealthCare Royalty Partners

Financing Includes $60 Million 8% Notes Convertible at $17.50 Per Share, and $10 Million Additional Funding Pursuant to a Revised Synthetic Royalty(R) Loan Agreement

NOVATO, Calif., July 1, 2014 — Raptor Pharmaceutical Corp. (NASDAQ:RPTP) today announced that it has entered into agreements for $70 million in funding from HealthCare Royalty Partners (HC Royalty) and its affiliates in a private placement. The funding includes $60 million in new convertible senior notes and an additional $10 million of funding pursuant to an amended and restated loan agreement, originally signed on December 20, 2012. The new capital will be used for expansion of the company’s manufacturing capacity, expansion of commercial operations in Europe, advancement of the company’s development programs and general corporate purposes, including working capital. Closing is expected to occur by the end of July 2014 and is subject to customary closing conditions under both the convertible note financing agreement and the amended and restated loan agreement.

Under the terms of the financing agreement, the convertible notes to be issued to HC Royalty and its affiliates will pay interest quarterly at a rate of 8.0% per year. The notes mature on August 1, 2019 unless earlier converted, redeemed or repurchased in accordance with their terms prior to such date. Prior to August 1, 2019 the notes are convertible into shares of Raptor common stock at an initial conversion rate of 57.14 shares per $1,000 principal amount of notes, subject to adjustment, which is equivalent to a conversion price of $17.50 per share, representing a 49.6% premium over the closing price of Raptor’s common stock of $11.70 per share on July 1, 2014. In addition, the notes are subject to automatic conversion into shares of Raptor common stock or redemption, at Raptor’s election subject to certain conditions, if Raptor’s share price is at or above 175% of the conversion price over a 30 consecutive day period. Any payment of the principal amount of the notes will be subject to a 10% payment premium.

The terms of the loan agreement signed December 20, 2012 have been revised to provide for an additional $10 million in funding. The base interest rate has been revised to an annual fixed rate of 8.0% compared to the original 10.75%. The Synthetic Royalty variable rate has been consolidated and revised to 8.0% on the first $50 million of revenue, from the original two-tier rate of 12.25% on the first $25 million and 6.0% on the second $25 million of net revenue. The second tier of 2.0% on net sales above $50 million remains unchanged. The scheduled maturity date of the term loans under the loan agreement is March 31, 2020. Starting on June 30, 2015, the term loans are scheduled to be repaid in equal quarterly principal payments of $3 million, with the remaining principal paid on the scheduled maturity date. All amounts owed under the loan agreement will continue to be secured by substantially all assets of the company.

“This financing with HC Royalty demonstrates their belief in Raptor’s future prospects, provides balance sheet strength, and reduces the cost of capital of our debt facility," stated Christopher M. Starr, Ph.D., Raptor’s chief executive officer. “At closing and based on our cash balance at the end of the first quarter, Raptor will have over $120 million in cash on our balance sheet, which will be used to advance our development pipeline and continue the build out of our commercial platform."

“Raptor’s franchise, including PROCYSBI, is an asset of significant value that has performed above our expectations. We believe nephropathic cystinosis continues to present a significant global market opportunity for the company," stated Clarke B. Futch, Founding Managing Director at HC Royalty. “The cost to develop and commercialize a new drug continues to escalate. Growing biopharmaceutical companies like Raptor need flexible financing options to move their efforts forward and we were able to accomplish that with this transaction."

Leerink Partners LLC served as financial advisor to Raptor in connection with the financing.
