(“WestRiver” and together with SVB, the “Lenders”), as a lender. Pursuant to the First Amendment, the Lenders consented to the Company’s entry into the Co-Development Agreement, dated as of January 9, 2020 (the “Co-Development Agreement”), between the Company and SFJ Pharmaceuticals X, Ltd., an SFJ Pharmaceuticals Group company (“SFJ”), pursuant to which SFJ will provide funding to the Company to support the global development of PB2452 and which required that the Company obtain the consent of SVB to grant SFJ a security interest in all of the Company’s assets, including intellectual property owned or controlled by the Company that is necessary for the manufacture, use or sale of PB2452. The First Amendment also provides that in the event that the Co-Development Agreement were terminated or the Company breached or was in default of the Co-Development Agreement (after giving effect to applicable grace periods), the Company will grant to the Lenders a security interest in an amount of unrestricted cash equal to at least the aggregate outstanding balance of all of the obligations under the Loan Agreement as security for the prompt payment of such obligations.
In connection with the First Amendment, the Company and the Lenders concurrently entered into an Intellectual Property Security Agreement, dated March 19, 2020 (the “IP Security Agreement”), granting the Lenders a security interest in all of the Company’s intellectual property.
