Amendment to Convertible Debentures issued on June 19, 2020, July 17, 2020, August 14, 2020 and November 13, 2020

As previously disclosed in the Reports of Foreign Private Issuer on Form 6-K filed with the SEC, pursuant to a securities purchase agreement dated June 19, 2020 with certain investor (the “Debenture Holder”), China Xiangtai Food Co., Ltd. (the “Company”) issued a convertible debenture in the amount of $700,000 on June 19, 2020, as amended (the “Fourth Convertible Debenture”), a convertible debenture in the amount of  $700,000 of principal on July 17, 2020, as amended (the “Fifth Convertible Debenture”), a convertible debenture in the amount of $300,000 on August 14, 2020, as amended (the “Sixth Convertible Debenture”), and a convertible debenture in the amount of  $300,000 on November 13, 2020, as amended (the “Seventh Convertible Debenture”, and together with the Fourth, Fifth and Sixth Convertible Debentures, the “2020 Convertible Debentures”). As of the date of this report, there are a total of $2,000,000 of principal, plus accrued and unpaid interest thereon, remain outstanding on the 2020 Convertible Debentures.

On April 14, 2021, the Company entered in an amendment agreement (the “Amendment Agreement”) with the Debenture Holder to amend the “Floor Price” of the Fourth Convertible Debenture to $0.80 per share.

Additionally, pursuant to the 2020 Convertible Debentures, the Company shall make monthly payments if the daily VMAP is less than the floor price for a period of ten (10) consecutive trading days (each such occurrence, a “Triggering Event”), beginning on the 30th day after the date of the Triggering Event, for so long as such conditions exist after a Triggering Event. Pursuant the Amendment Agreement, such monthly payment of the Fourth Convertible Debenture shall no longer apply and all amount of principal and accrued interest that remain outstanding shall be due and payable on the maturity date of the Fourth Convertible Debenture, which is June 19, 2021. Such monthly payment of the remaining 2020 Convertible Debentures is deferred until June 30, 2021.

The Amendment Agreement is filed as Exhibits 10.1 to this Report of Foreign Private Issuer on Form 6-K and such document is incorporated herein by reference. The foregoing is only a brief description of the material terms of the Amendment Agreement and does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to such exhibit.
