On December 27, 2013, Halozyme Therapeutics, Inc. (the Company) and its subsidiary, Halozyme, Inc. entered into an Amended and Restated Loan and Security Agreement (the Loan Agreement) with Oxford Finance LLC and Silicon Valley Bank, amending and restating in its entirety the Loan and Security Agreement dated as of December 28, 2012 (Original Loan Agreement). The Original Loan Agreement provided for a $30 million secured single-draw term loan facility with a maturity date of January 1, 2017. The original term loan was fully drawn at close.

The Loan Agreement extends the original $30 million term loans and provides for an additional $20 million in new term loans, bringing the total term loan balance to $50 million. Upon closing of the Loan Agreement, the company received approximately $19 million, net of accrued interest. The proceeds are to be used for working capital and general business requirements.

The amended and restated term loan facility matures on January 1, 2018. The amended and restated term loan facility is secured by substantially all of the assets of the company and Halozyme, Inc., except that the collateral does not include any equity interests in Halozyme, Inc., any intellectual property (including all licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The amended and restated term loan repayment schedule provides for interest only payments for the first year, followed by consecutive equal monthly payments of principal and interest in arrears starting in February 2015 and continuing through the maturity date.

The Loan Agreement provides for a 7.55% interest rate on the term loans and a final payment equal to 8.5% of the initial principal amount of the term loans, which is due when the term loans become due or upon the prepayment of the facility. The Loan Agreement contains customary representations, warranties and covenants by the company, as well as customary events of default and indemnification obligations of the company.
