On July 31, 2020, Zosano Pharma Corporation (the “Company”) entered into an amendment (the “Amendment”) to that certain Business Understanding Agreement, dated September 13, 2018, with CSP Technologies, Inc. (“CSP”) (the “Original Agreement,” and together with the Amendment, the “Amended Agreement”), which became a material agreement to the Company upon the execution of the Amendment.

Pursuant to the Amended Agreement, CSP agreed to provide services related to the manufacture and assembly of a component (the “Product”) of Qtrypta^™ (M207) (“Qtrypta”). Under the Amended Agreement, the parties expressed their mutual intent to enter into a commercial supply agreement (“Supply Agreement”) addressing certain of the terms set forth in the Amended Agreement. The Amended Agreement provides that if the Company ceases to purchase the Product from CSP and a Supply Agreement is not entered into, then the Company may be required to pay CSP up to $2.5 million; however, no such payment will be required in the event of CSP’s material breach. The Company may be required to pay CSP an additional payment of up to $4.6 million if the Company ceases to purchase the Product from CSP and a Supply Agreement is not entered into, except that no such payment will be required in the event of CSP’s material breach or if the U.S. Food and Drug Administration does not approve Qtrypta.

The foregoing description of the Amended Agreement is not complete and is qualified in its entirety by reference to the text of the Original Agreement and the Amendment, copies of which are filed herewith as Exhibits 10.1 and 10.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
