On May 1, 2019, Celgene terminated its rights to elect an option to terminate the Celgene License Agreement upon the occurrence of a First Trigger Event, Second Trigger Event or Early Exercise. As a result, the Company is free to negotiate and enter into any agreement with respect to an acquisition of all or substantially all of the business or assets of the Company whether by merger, sale of equity or assets, or otherwise and to consummate the same as it sees fit. On November 15, 2019, Celgene and the Company entered into an amendment to the Celgene License Agreement (the “Amended Celgene License Agreement”) to terminate certain of Celgene’s ABI-009 product supply obligations and to transfer control over certain regulatory filings under the original Celgene License Agreement from Celgene to the Company. The Amended Celgene License Agreement also waived the obligations related to certain development milestone payments and waived the liability related to 2016 and 2017 licensed drug manufacturing costs of $1.2 million and $2.7 million, respectively. On August 30, 2021, the Company and Celgene entered into Amendment No. 1 (the “Amendment”) to the Amended Celgene License Agreement related to certain intellectual property rights of Celgene pertaining to the compound known as ABI-009. Under the terms of the Amendment, the Company paid Celgene $5.8 million representing 50% of the previously outstanding payment obligation under the terms of the Amended Celgene License Agreement, following the Effective Time of the PIPE Financing. Pursuant to the terms of the Amendment, the remaining previously outstanding payment obligation of $5.8 million, is due on the third anniversary of the Effective Time plus any accrued and unpaid interest due thereon (“Balloon Payment”). The Balloon Payment shall accrue interest, beginning as of the Effective Time until paid in full, at a rate equal to 4.0% per annum based on the weighted average amount outstanding during the applicable calendar quarter, and interest shall be payable quarterly in arrears. In addition, the parties agreed to amend the royalty rates payable to Celgene based on net sales of products subject to the Amended Celgene License Agreement. On December 8, 2020, the Company entered into a license agreement (“EOC License Agreement”) with EOC Pharma (Hong Kong) Limited (“EOC”) under which the Company received $14.0 million in January 2021 in non-refundable upfront consideration as partial payment for the rights and licenses granted to EOC by the Company for the further development and commercialization of ABI-009 in the People’s Republic of China, Hong Kong Special Administration Region, Macao Special Administrative Region and Taiwan (the “Licensed Territory”).
