In the event of a Dilutive Event at any time from the Effective Time through the six (6) month anniversary of the Effective Time, any such adjustment shall occur immediately after the completion of such period. As of March 30, 2021, the New Debentures have an aggregate outstanding principal balance of $200 as a result of conversions of the New Debentures (see note 15 below).
