Inc. (“Regen”) as of December 16, 2019. For purposes of this Agreement Regen and KCL may be also referred to singularly
or collectively as “Licensor”. For purposes of this Agreement Regen, KCL and Zander may be collectively referred to

WHEREAS:


On
June 23, 2015 Zander and Regen have entered into an agreement, as amended(“License Agreement”) whereby Regen granted
to Zander an exclusive worldwide right and license for the development and commercialization of certain intellectual property
controlled by Regen for non-human veterinary therapeutic use for a term of fifteen years.


On
December 17, 2018 Regen, KCL and Zander entered into a License Assignment And Consent agreement whereby Regen transferred and
assigned to KCL all rights, duties, and obligations of Regen under the License Agreement and KCL agreed to assume such duties
and obligations thereunder and be bound to the terms of the License Agreement with respect thereto. KCL is a wholly owned subsidiary
of Regen and Regen acknowledges that Regen will benefit from any payments made to KCL.


Pursuant
to the License Agreement, Zander is obligated to pay Licensor an annual non-refundable payment of one hundred thousand US dollars
($100,000) on each anniversary of the effective date of the License Agreement and Zander is obligated to pay Licensor minimum
annual royalties of ten thousand US dollars ($10,000) payable per year on each anniversary of the effective date of the License
Agreement. Collectively, minimum annual payments due by Zander to the Licensor pursuant to the License Agreement equal $110,000
USD per annum (“License Agreement Payments”).


As
of the date of this Agreement, Zander has failed to pay $42,000 USD of the License Agreement Payments due and payable by June
2019.


On
September 30, 2018 Regen issued a convertible promissory note in the principal amount of $350,000 USD (“Convertible Note”)
to Zander for cash payments paid by Zander to Regen equaling $350,000 USD. A onetime interest charge of 10% of the principal amount
shall be applied to the principal amount of the Convertible Note (“Convertible Note One Time Charge”). On June 27,
2019 Zander converted $340,000 of the principal amount of the Convertible Note into 194,285,714 shares of the Series A Preferred
stock of Regen (“Conversion Shares”).


As
of the date of this Agreement, exclusive of amounts due to Zander pursuant to the Convertible Note, Zander is owed by Regen the
principal amount of $75,900 USD resulting from Notes Payable issued by Regen to Zander (“Regen Notes”) and Zander
is owed $4,328 USD resulting from interest accrued but unpaid on the Regen Notes (“Accrued Interest”).





THEREFORE,
IT IS AGREED AS FOLLOWS:


		1.	On
                                         or before December 20, 2019 Zander shall return the Conversion Shares to Regen for cancellation
                                         (“Rescission”) and upon Rescission the parties agree that the original principal
                                         balance of the Convertible Note of $350,000 USD shall become a liability of Regen to
                                         Zander. Rescission shall be deemed to have occurred upon the date of submission to Regen
                                         by Zander of the Conversion Shares along with written instructions by Zander directing
                                         Regen and/or Regen’s Transfer Agent to cancel the Conversion Shares (“Return
                                         Date”). Subsequent to the Rescission the principal Balance of $350,000 USD shall
                                         no longer be convertible into equity securities of Regen and shall be applied to Annual
                                         License Agreement Payments in accordance with Section 3 of this Agreement.






		2.	As
                                         of a result of the Rescission, as of the Return Date Regen shall owe Zander the aggregate
