(1)	As described in the registration statement on Form S-1 (File No. 333-229853) of Trine Acquisition Corp. (the "Issuer") under the heading "Description of Securities-Founder Shares," the shares of Class B common stock of the Issuer (the "Class B Shares") will automatically convert into shares of Class A common stock of the Issuer (the "Class A Shares") at the time of the issuer's initial business combination or earlier at the option of the holder, in each case, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and certain anti-dilution rights.
(2)	On December 9, 2020, the Issuer consummated its initial business combination (the "Business Combination") with Desktop Metal, Inc., a Delaware corporation ("Desktop Metal"). In connection with the Business Combination, each Class B Share converted to one Class A Share.
Remarks: As a result of the Business Combination, the reporting person has ceased to be a director of the Issuer.
