Explanation of Responses:

( 1 )Shares of the Issuer's Class B Common Stock are automatically convertible into shares of the Issuer's Class A Common Stock at the time of the Issuer's initial business combination or earlier at the option of the holders thereof, in either case on a one-for-one basis, subject to certain adjustments. The Class B Common Stock has no expiration date. ( 2 )Includes up to 900,000 shares of Class B Common Stock that may be forfeited if the underwriters in the Issuer's initial public offering do not exercise the overallotment option in full. ( 3 )Securities are held by Rotor Sponsor LLC ("Sponsor") and indirectly by its managing member, Brian Finn, who is also the Issuer's Chief Executive Officer and a member of the Issuer's Board of Directors. Mr. Finn disclaims beneficial ownership of the securities held by Sponsor except to the extent of any pecuniary interest therein.

Remarks: This Form 3/A is being filed to amend and restate the original Form 3 filed by the reporting persons on January 14, 2021 in connection with the initial public offering of Rotor Acquisition Corp. (the "Issuer") to correct an error in reporting the beneficial ownership of warrants to purchase Class A Common Stock. The warrants reported in the original Form 3 were not issued and outstanding as of the date of the event requiring the filing of the original Form 3 and should not have been included therein as securities beneficially owned by the reporting persons. On September 24, 2021, the Issuer completed its initial business combination and, in connection therewith, changed its name to Sarcos Technology and Robotics Corporation.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
