NOTE 13 – ASSET PURCHASE AGREEMENT WITH HEALION 

On February 2, 2023, the Company entered into an asset purchase agreement (the “Healion Asset Purchase Agreement”) with Healion Bio Inc., (“Healion”) pursuant to which the Company acquired all the pre-clinical infectious disease assets of Healion, including its portfolio of next-generation antiviral technology assets. Healion’s drug portfolio includes a class of broad-spectrum small molecule oral antiviral drug candidates with a novel host-directed mechanism of action, including TNX-3900, formerly known as HB-121. As consideration for entering into the Healion Asset Purchase Agreement, the Company paid $1.2 million to Healion. Because the Healion intellectual property was acquired prior to U.S. Food and Drug Administration (FDA) approval, the cash consideration totaling $1.2 million, was expensed as research and development costs since there is no alternative future use and the acquired intellectual property does not constitute a business.
