Explanatory Note

 

This Amendment No. 4 (this “Amendment”) amends and supplements the Schedule 13D filed on behalf of the Reporting Persons with the Securities and Exchange Commission on February 10, 2020, Amendment No. 1 thereto filed with the Securities and Exchange Commission on November 5, 2021, Amendment No. 2 thereto filed with the Securities and Exchange Commission on February 10, 2022 and Amendment No. 3 thereto filed with the Securities and Exchange Commission on March 21, 2022 (together, the “Schedule 13D”). Except as specifically provided herein, this Amendment does not modify or amend any of the information previously reported in the Schedule 13D. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

 

Item 4.

Purpose of Transaction

 

Item 4 of the Schedule 13D is supplemented to add the following:

 

Pursuant to that certain Agreement and Plan of Merger, dated April 12, 2022 (the “Merger Agreement”), by and among the Issuer, GlaxoSmithKline plc (“GSK”) and Orikum Acquisition Inc. (“Acquisition Sub”), Acquisition Sub merged with and into the Issuer with the Issuer surviving as a wholly owned subsidiary of GSK (the “Merger”). Upon the closing of the Merger on July 1, 2022: (i) each share of Common Stock was automatically cancelled and converted into the right to receive an amount in cash equal to $55.00, without interest and less any applicable withholding taxes; (ii) each Series A Warrants was automatically cancelled and converted into the right to receive amount in cash equal to $45.98 per share of the Common Stock underlying the Series A Warrants; and (iii) all options that were outstanding and unexercised as of immediately prior to the closing of the Merger accelerated vesting in full and were automatically cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (a) the excess, if any, of $55.00 less the exercise price per share of such option, and (b) the number of shares of Common Stock issuable upon exercise in full of such option.

 

Item 5.

Interest in Securities of the Issuer

 

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

 

As the result of the Merger, the Reporting Persons no longer beneficially own any shares of Common Stock. As such, the Reporting Persons no longer have any voting or dispositive power over any shares of Common Stock.

 

Except as described herein, during the past sixty (60) days, there were no other purchases or sales of shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, by the Reporting Persons or any person or entity for which the Reporting Persons possess voting or dispositive control over the securities thereof.

 

As a result of the Merger, the Reporting Persons ceased to be the beneficial owners of more than five percent (5%) of the Common Stock on July 1, 2022.

 

Item 6.

Contracts, Arrangements, Understandings, or Relationships With Respect to Securities of the Issuer
