( 1 )On August 29, 2019, Issuer completed a merger transaction (the "Merger") pursuant to an Agreement and Plan of Merger, dated May 29, 2019, by and among Issuer, DT Merger Sub, Inc., and DermTech Operations, Inc., formerly known as DermTech, Inc. ("DermTech Operations"), as filed with the Securities and Exchange Commission on Form 8-K on May 29, 2019 (the "Merger Agreement"). Pursuant to the Merger Agreement, all issued and outstanding common stock of DermTech Operations converted into and beecame common stock of Issuer, and all issued and outstanding restricted stock units of DermTech Operations converted into and became restricted stock units with the right to receive Issuer common stock. ( 2 )(Continued from Footnote 1) On August 29, 2019, following the completion of the Merger, Issuer effected a reverse stock split at a ratio of one share for every two shares of Issuer common stock outstanding (the "Reverse Stock Split"). ( 3 )These shares of Issuer common stock were received in connection with the Merger in exchange for shares of DermTech Operations common stock. Each share of DermTech Operations common stock was cancelled and exchanged for the right to receive 1.16150415935026 shares of common stock of Issuer. The shares of common stock of Issuer reported reflect any necessary adjustments to account for the Reverse Stock Split. ( 4 )The shares of Issuer common stock underlying these restricted stock units have fully vested and will be released to the reporting person on the earliest to occur of (i) December 31, 2019, (ii) a change of control of Issuer, or (iii) the death of reporting person. ( 5 )These restricted stock units of Issuer were received in connection with the Merger in exchange for restricted stock units of DermTech Operations. Each restricted stock unit to receive one share of DermTech Operations was cancelled and exchanged for a restricted stock unit to receive 1.16150415935026 shares of Issuer common stock, on the same terms and conditions applicable to the original award. The shares of Issuer common stock underlying the restricted units reported reflect any necessary adjustments to account for the Reverse Stock Split. ( 6 )Each restricted stock unit represents a contingent right to receive one share of Issuer common stock.
