NOTE 4 — LICENSE AGREEMENTS

Xoma License Agreement

On December 6, 2017, the Company entered into a license agreement (“License Agreement”) with XOMA Corporation (“Xoma”), through its wholly-owned subsidiary, XOMA (US) LLC, pursuant to which Xoma granted an exclusive global license to the Company to develop and commercialize Xoma 358 (formerly X358, now RZ358) for all indications. On January 7, 2019, the License Agreement was amended whereby the Company was required to make five cash payments to Xoma totaling $8.5 million on or before specified staggered future dates (the “Future Cash Payments”).  The Future Cash Payments are due for $1.5 million by September 30, 2019, $1.0 million by December 31, 2019, $2.0 million by September 30, 2020, $2.0 million by June 30, 2020, and $2.0 million by September 30, 2020. As a result of this amendment to the License Agreement, the Company recognized a liability in January 2019 for the entire $8.5 million of Future Cash Payments.

The amended License Agreement provides that if future qualified financings occur before the Future Cash Payments are fully paid, the Company is required to pay Xoma 15% of the net proceeds from such financings (“Early Payments”) to be credited against the remaining unpaid Future Cash Payments in the reverse order of their future payment date.  Obligations to make the Future Cash Payments following a qualified financing and the obligations to make Early Payments shall end when the Future Cash Payments are fully paid for the total of $8.5 million.  As discussed in Note 5, the Company completed equity financings for net proceeds of approximately $22.6 million in July and August 2019, which resulted in the obligation to make Early Payments of approximately $3.4 million. Presented below is a summary of the amounts payable under the amended License Agreement along with cash payments made for the three months ended September 30, 2019 (in thousands):

The amendment to the License Agreement also revised the amount the Company is required to expend on development of RZ358 and related licensed products and revised provisions with respect to the Company’s diligence efforts in conducting clinical studies. Additionally, upon the future commercialization of RZ358, the Company would be required to pay royalties to Xoma based on the net sales of the related products.

As of September 30, 2019, Xoma owns approximately 8.1 million shares of the Company’s Common Stock. The License Agreement provides Xoma with the right and option to require the Company to use its best efforts to facilitate orderly sales of the shares to a third party or purchase the shares (the “Put Option”). Under the amended License Agreement, the Put Option becomes effective if the Company fails to list its shares of Common Stock on the Nasdaq Stock Market or a similar national exchange prior to December 31, 2019. Xoma may exercise the Put option for up to a total of 2.5 million shares of Common Stock for the fiscal year ending December 31, 2020, and up to an additional 2.5 million shares thereafter. If the Put Option becomes exercisable, the Company may be required to pay a price per share equal to the average of the closing bid and asked prices of the Common Stock on the date the Put Option is exercised.

ActiveSite License Agreement

On August 4, 2017, the Company entered into a Development and License Agreement with ActiveSite Pharmaceuticals, Inc.  (“ActiveSite”) pursuant to which the Company acquired the rights to ActiveSite’s Plasma Kallikrein Inhibitor program (“PKI Program”).  The Company desires to use the PKI Program to develop, file, manufacture, market and sell products for diabetic macular edema and other human therapeutic indications. The ActiveSite License Agreement requires various milestone payments ranging from $1.0 million to $10.0 million when milestone events occur, up to $36.0 million of aggregate milestone payments. The first milestone payment for $1.0 million is due after completion of the preclinical work and submission of an IND application to the FDA. The Company is also required to pay royalties equal to 2.0% of any sales of products that use the PKI Program, up to a maximum of $10.0 million in total royalty payments. Through September 30, 2019, no milestone payments and royalties have been incurred.
