( 3 )Pursuant to the Merger Agreement, 50% of the RSUs and PSUs reported hereby (each, a "Deemed Vested RSU" or a "Deemed Vested PSU," respectively) were, at the effective time of the Issuer Merger (the "Effective Time"), automatically canceled and converted into the right to receive an amount in cash (without interest and subject to applicable withholding taxes) equal to the product of (i) the total number of shares of the Issuer's Class A common stock, par value $0.0001 per share ("Class A Common Stock"), subject to such Deemed Vested RSU or such Deemed Vested PSU (with such Deemed Vested PSU being deemed achieved at maximum performance), respectively, as of immediately prior to the Effective Time, and (ii) $26.00. ( 4 )Pursuant to the Merger Agreement, each RSU reported hereby that was outstanding immediately prior to the Effective Time and not a Deemed Vested RSU (an "Unvested RSU") and each PSU reported hereby that was outstanding immediately prior to the Effective Time and not a Deemed Vested PSU (an "Unvested PSU") was, at the Effective Time, automatically canceled and converted into an award representing the right to receive an amount in cash (without interest and subject to applicable withholding taxes) equal to the product of (i) the total number of shares of Class A Common Stock subject to such Unvested RSU or such Unvested PSU (with such Unvested PSU being deemed achieved at maximum performance), respectively, as of immediately prior to the Effective Time (a "Deferred Cash RSU Award" or "Deferred Cash PSU Award," respectively), and (ii) $26.00. ( 5 )Each Deferred Cash RSU Award or Deferred Cash PSU Award will, subject to the holder's continued service with Parent or its affiliates through the applicable vesting dates, vest and be payable on the earlier of (i) the same time as the Unvested RSU or Unvested PSU for which the Deferred Cash RSU Award or Deferred Cash PSU Award, respectively, was exchanged would have vested and been payable pursuant to its service-based vesting schedule and (ii) December 28, 2023, in each case, subject to full accelerated vesting upon a termination of employment with Parent or its affiliates without "cause" or a resignation for "good reason."
