The Company will execute and deliver to Viscaria and its representatives all documents and instruments required to transfer and vest good and valid title in and to the Converted Shares to Viscaria in accordance with the terms of this Agreement, including by recording the conversion of the Contributed Shares and the issuance of the Converted Shares, in each case, on the books and records of the Company.

The consummation of the transactions contemplated by this Agreement, and the performance by the Parties of their respective agreements, covenants and obligations hereunder (collectively, the “Closing”) will take place remotely via the electronic exchange of counterpart signature pages on the date hereof or in such other manner or on such other date or time as the Parties mutually agree. Except as otherwise provided in this Agreement, all actions to be taken and all documents to be executed and delivered at the Closing shall be deemed to have been taken, delivered and executed simultaneously, and no action shall be deemed taken nor any documents deemed executed or delivered until all have been taken, delivered and executed.

Consideration and Cash Consideration (together, the “Recapitalization”) shall be treated collectively as a “recapitalization” (within the meaning of Section 368(a)(1)(E) of the Code and the U.S. Treasury Regulations thereunder) that is governed by Sections 354 and 356 of the Code, (ii) the Cash Consideration (but not the Stock Consideration) shall be treated as “boot” for purposes of Section 356(a) of the Code and the Treasury Regulations thereunder, and (iii) Viscaria’s “ratable share” of the Company’s earnings and profits for purposes of determining the portion of the Cash Consideration that may be treated as a dividend under Section 356(a)(2) of the Code shall be calculated as set forth in Exhibit B. Unless otherwise required by a “determination” within the meaning of Section 1313 of the Code (or similar provision of other tax law), the Parties agree that they will take no position that is inconsistent with the foregoing or Exhibit B on any tax return (including on any IRS Form 1042-S), before any taxing authority, or in any proceeding with respect to Taxes.
