** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Shares beneficially owned are 30,155 shares more than the previously filed Form 4s due to an error reporting the shares owned on December 15, 2020. An amendment to the original Form 4 has been filed to correct the error.
(2) The reported shares were withheld to cover the Reporting Person's tax withholding liability in connection with a portion of a time-based restricted stock award that vested on December 1, 2021.
(3) Each restricted stock unit represents a contingent right to receive one share of Inogen common stock.
(4) Subject to the reporting person's continued service, 25% of the restricted stock units shall vest on March 1, 2021, and 1/16th of the restricted stock units shall vest every three months thereafter on the 1st day of the month, subject to the reporting person continuing to be a service provider through each such vesting date.
