The Note does not bear interest, matures on the date of consummation the Business Combination and is subject to customary events of default. The Restated Note will be repaid only to the extent that the Company has funds available to it outside of its trust account established in connection with its initial public offering.

The foregoing description of the Restated Note is qualified in its entirety by reference to the full text of the Restated Note, a copy of which is filed herewith as Exhibit 10.1 hereto and incorporated by reference herein.
