Explanation of Responses:

1. On December 26, 2019, Boyalife (Hong Kong) Ltd. ("Boyalife HK") sold to Boyalife Asset Holding II, Inc. ("Boyalife AH") an aggregate of 683,824 shares of the Issuer's common stock for an aggregate purchase price of $2,227,134 (or $3.33 per share) and warrants to purchase 352,942 shares of issuer common stock for an aggregate purchase price of $10.00. Boyalife AH is 100% owned by Boyalife Group, Inc., which is 100% owned by Mr. Xiaochun Xu, and Boyalife HK is owned 100% by Ms. Yishu Li, the spouse of Mr. Xiaochun Xu. Accordingly, the transaction resulted in a change in the form of beneficial ownership of the shares and did not result in a change in Mr. Xu's and Ms. Li's pecuniary interest in the shares.

2. On December 20, 2019, Boyalife AH sold to a third party in a private transaction a participation interest in the Second Amended and Restated Convertible Promissory Note, dated April 16, 2018, issued by the Issuer and held by Boyalife AH (the "Convertible Note"). Boyalife AH sold to the third party a participation interest in the Convertible Note equal to $1,080,000 in face value of the Convertible Note plus interest accruing thereon after December 20, 2019. The Convertible Note and interest thereon is convertible into shares of Issuer common stock at a conversion price of $1.80 (subject to adjustment), with the participation interest representing a right to receive 600,000 conversion shares as of December 20, 2019, plus an additional share for each $1.80 of interest accrued thereafter, subject to a conversion blocker of 4.99%.

3. Represents the amount of principal and interest remaining under the Convertible Note as of the date of this Form 4 that is not subject to the participation interest described in preceding Note 2.

Remarks:

This amendment to Form 4 is being filed to revise certain transaction codes in the originally filed Form 4 and to revise footnote 2 therein to provide additional detail. All share numbers, warrant numbers, exercise prices, and conversion prices on this Form 4 reflect the Issuer's one-for-ten reserve stock split of its common stock that occurred on June 4, 2019.
