Genius Sports and the other parties signatory hereto have agreed to modify the Investor Rights Agreement as set forth in this letter agreement. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Investor Rights Agreement.

The parties hereto acknowledge and agree that, notwithstanding anything to the contrary set forth in the Investor Rights Agreement and by way of amendment thereto, (i) conditioned on and following the public commencement of the first Underwritten Shelf Takedown following the date of this letter agreement, the Holder shall be permitted to Transfer by way of pledge or other security interest up to 60% of the Registrable Securities held by the Holder and (ii) conditioned on and following the closing of the first Underwritten Shelf Takedown following the date of this letter agreement, the Holder shall be permitted to Transfer by way of pledge or other security interest up to 100% of the Registrable Securities held by the Holder, meaning that, in the case of this clause (ii), all and any restrictions on the Holder in the Investor Rights Agreement in respect of Transfer by way of pledge or other security interest (but not by sale) are hereby removed. The Holder hereby agrees to forgo exercising his right to participate in the first Underwritten Shelf Takedown following the date of this letter agreement.

Except as set forth above, the Investor Rights Agreement shall continue in full force and effect with respect to all parties signatory thereto. Except as expressly set forth herein, nothing in this letter agreement shall be construed to amend, modify or waive any other provisions of the Investor Rights Agreement nor shall this letter agreement limit, restrict, modify, alter, amend or otherwise change in any manner the other rights and obligations of the parties under the Investor Rights Agreement.
