SCHEDULE I

Advisor Share Issuance Based on Equity Raised

In exchange for services rendered in connection with the proposed Business Combination, Roth shall be issued up to 300,000 Advisor Shares, equal to the Fixed Compensation Shares plus a number of Variable Compensation Shares equal to the product of (x) the quotient of Equity Raised divided by $50.0 million, multiplied by (y) 200,000. For example, if Equity Raised equals $31.5 million then total compensation would be the Fixed Compensation Shares plus 126,000 Variable Compensation Shares (calculated as $31.5 million divided by $50 million, multiplied by 200,000) for total Advisor Shares equal to 226,000. For the avoidance of doubt, Roth shall receive 100,000 Fixed Compensation Shares regardless of the amount of Equity Raised, if any.

For purposes of Schedule I:

the term “Equity Raised” means the gross proceeds available to the post-Business Combination Company immediately after the closing of the Business Combination, consisting of: (a) the gross proceeds received from a capital raising transaction involving the equity securities or equity-linked instruments of Tigo, provided, however that the $50.0 million of proceeds from the sale of convertible promissory notes by Tigo to L1 Energy Capital Management S.à.r.l. shall be excluded from the calculation of Equity Raised; (b) the gross proceeds received from a capital raising transaction involving the equity securities of the Company; and (c) the amount remaining in the Company’s trust account after giving effect to any redemptions.

the term “Fixed Compensation Shares” means the 100,000 Advisory Shares issued to Roth in exchange for M&A advisory fees, regardless of the amount of Equity Raised.

the term “Variable Compensation Shares” means up to 200,000 shares issued to Roth based on the amount of Equity Raised.
