Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Merger of Quellis and the Issuer

On January 28, 2021, the Issuer acquired Quellis pursuant to an Agreement and Plan of Merger, dated January 28, 2021 (the “Merger Agreement”), by and among the Issuer, Cabo Merger Sub I, Inc., a Delaware corporation and wholly owned subsidiary of the Issuer (“First Merger Sub”), Cabo Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Issuer (“Second Merger Sub”), and Quellis. Pursuant to the Merger Agreement, First Merger Sub merged with and into Quellis, pursuant to which Quellis was the surviving entity and became a wholly owned subsidiary of the Issuer (the “First Merger”). Immediately following the First Merger, Quellis merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity (the “Second Merger,” together with the First Merger, the “Merger”). Under the terms of the Merger Agreement, the Issuer issued to the stockholders of Quellis (including Perceptive Xontogeny and Xontogeny) an aggregate of 3,332,669 shares of Common Stock and 50,504 shares of Series X Convertible Preferred Stock.


Series X Convertible Preferred Stock

The terms of the Series X Convertible Preferred Stock are set forth in the Certificate of Designation filed by the Issuer with the Secretary of State of the State of Delaware (the “Certificate of Designation”) on January 28, 2021. Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Convertible Preferred Stock equal, on an as-if-converted-to-Common-Stock- basis, and in the same form as dividends actually paid on shares of Common Stock. Subject to approval by the Issuer’s stockholders, the Series X Convertible Preferred Stock is convertible into Common Stock at rate of 1,000 shares of Common Stock for every one share of Series X Convertible Preferred Stock that is converted. Except as otherwise required by law, the Series X Convertible Preferred Stock does not have voting rights. However, as long as any shares of Series X Convertible Preferred Stock are outstanding, the Issuer is obligated not to, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series X Convertible Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series X Convertible Preferred Stock or alter or amend the Certificate of Designation, amend or repeal any provision of, or add any provision to, the Certificate of Incorporation or bylaws of the Issuer, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of preferred stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series X Convertible Preferred Stock, (ii) issue further shares of Series X Convertible Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of Series X Convertible Preferred Stock, or (iii) enter into any agreement with respect to any of the foregoing. Additionally, the approval of the holders of a majority of the Series X Convertible Preferred Stock is required for certain change of control transactions, provided that this approval right will terminate upon approval by the Issuer’s stockholders of the conversion of the Series X Convertible Preferred Stock.

Following stockholder approval of the conversion, (i) effective as of 5:00 p.m. (New York City time) on the fourth business day after the date on which such stockholder approval is received, each share of Series X Convertible Preferred Stock then outstanding automatically converts into 1,000 shares of Common Stock, and (ii) at any time thereafter at the option of the holder thereof, into 1,000 shares of Common Stock, in the case of each of (i) and (ii) subject to certain beneficial ownership limitations, including that a holder of Series X Convertible Preferred Stock is prohibited from converting shares of Series X Preferred Stock into shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage (to be initially set at 9.99% and thereafter adjusted by the holder between to a number between 4.99% and 19.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion.

Private Placement

In connection with the Merger, on January 28, 2021, the Master Fund and Perceptive Xontogeny and certain other investors entered into a Stock Purchase Agreement (the “Purchase Agreement”) with the Issuer. Pursuant to the Purchase Agreement, the Master Fund and Perceptive Xontogeny acquired the shares of Series X Convertible Preferred Stock set forth in Item 5(c) in a private placement (the “Private Placement”). The Private Placement closed on February 1, 2021.

Registration Rights Agreement

In connection with the Private Placement, the Master Fund and Perceptive Xontogeny entered into a registration rights agreement with the Issuer (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Issuer will prepare and file a resale registration statement with the SEC within 90 days following the closing of the Private Placement.

The foregoing summaries of the Merger Agreement, the Series X Convertible Preferred Stock, the Purchase Agreement, and the Registration Rights Agreement do not purport to be complete and are qualified in their entirety by reference to the Merger Agreement, the Certificate of Designation, the Purchase Agreement, and the Registration Rights Agreement, each of which is filed as an exhibit hereto and incorporated by reference herein.
