Explanation of Responses:

( 1 )Received pursuant to the Agreement and Plan of Merger, dated as of October 5, 2020, as amended by Amendment No. 1 to Agreement and Plan of Merger dated as of November 18, 2020 (as amended, the "Merger Agreement"), by and among Romeo Power, Inc. (f/k/a RMG Acquisition Corp.) (the "Issuer"), RMG Merger Sub, Inc., a wholly owned subsidiary of the Issuer ("Merger Sub"), and Romeo Systems, Inc. ("Legacy Romeo"), pursuant to which Merger Sub merged with and into Legacy Romeo, with Legacy Romeo surviving the merger (the "Merger"). As a result, Legacy Romeo became a wholly-owned subsidiary of the Issuer, with the stockholders of Legacy Romeo becoming stockholders of the Issuer. ( 2 )The number of shares of Common Stock subject to this option that will vest will be an amount corresponding to the average of the closing price per share of Common Stock on the New York Stock Exchange on each of the five trading days (the "Liquid Share Price") immediately following the 180th day following December 29, 2020 (such 180th day, the "Liquidity Date"), which is the date on which the Merger was consummated. If the Liquid Share Price is $6.6869-$8.9452, then the cumulative number of shares that will vest is 926,795. If the Liquid Share Price is $8.9453-$11.9272, then the cumulative number of shares that will vest is 1,853,591. (continue with footnote (3)) ( 3 )If the Liquid Share Price is $11.9273-$14.9092, then the cumulative number of shares that will vest is 3,243,781. If the liquid share price is equal to or greater than $14.9093, then the cumulative number of shares that will vest is 4,633,978. Any shares subject to the option granted to Mr. Patterson that do not vest based on the Liquid Share Price targets aforementioned will be forfeited. In addition, if Mr. Patterson's employment is terminated for cause, due to his resignation without good reason or due to his death or disability, all of the shares subject to this option, including any vested shares subject to the option, will be forfeited. ( 4 )The expiration date is the earlier of (i) August 12, 2023 or (ii) five (5) business days following the Liquidity Date.

Remarks: This report is being filed to amend the reporting person's Form 4 filed December 31, 2020 to correct inadvertent errors with respect to (i) the number of shares reported in Table II, Columns 5, 7 and 9 and (ii) the disclosure in footnote 2 describing the respective stock option's vesting schedule.
