Id	Content
F1	Represents a grant of restricted stock units ("RSUs") under the Enanta Pharmaceuticals, Inc. ("Enanta") 2019 Equity Incentive Plan. Each RSU represents the contingent right to receive, upon vesting of the unit, one share of Enanta common stock. The RSUs vest in equal annual installments over four years from the date of grant (November 19, 2021). The restricted stock unit shares that vest will be issued on the first December 1 after the applicable vesting date, subject to withholding of a portion of the vested shares to satisfy tax withholding requirements.
F2	Such option will become exercisable (subject to the optionholder's continued employment) quarterly in substantially equal installments (any fractional shares to be cumulated and to become exercisable at the end of the earliest succeeding quarterly period in which a whole share equivalent is accumulated) over four years from the date of grant (November 19, 2021).
