(the “Issuer”). Initially capitalized terms used in this Amendment No. 14 that are not otherwise defined herein shall have the same meanings attributed to them in the Schedule 13D. Except as expressly provided herein, all Items of the Schedule 13D remain unchanged. This is the final amendment to the Schedule 13D and constitutes an “exiting filing” for the Reporting Persons.

ITEM 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and supplemented as follows:

(a) See rows (11) and (13) of the cover pages to this Schedule 13D for the aggregate number of shares of Common Stock and percentages of the shares of Common Stock beneficially owned by each of the Reporting Persons.

(b) See rows (7) through (10) of the cover pages to this Schedule 13D for the number of shares of Common Stock as to which each Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.

(c) On June 21, 2022, the Reporting Persons disposed of (i) 139,289,200 shares of Common Stock and (ii) a warrant to purchase 40,464,855 shares of Common Stock pursuant to that certain Warrant No. 1 dated February 16, 2016 (the “R1 Warrant”) upon the effectiveness of the merger of R1 Merger Sub with and into the Issuer, pursuant to the Transaction Agreement. At the effective time of the Transactions, each outstanding share of Common Stock was converted into one share of NewR1 Common Stock and the R1 Warrant was converted into a warrant to purchase shares of NewR1 Common Stock with substantially the same terms and conditions as the R1 Warrant. The Reporting Persons did not enter into any transactions in the shares of Common Stock during the past sixty days.

(d) No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, such shares of Common Stock.

(e) June 21, 2022.
