F1 Each restricted stock unit gives the holder the right to receive one share of the Issuer's common stock upon vesting. The units vest after six months, as long as the holder continues to provide service through the vesting date. After the units vest, the holder may choose to delay receiving the shares until the earlier of a qualifying distribution event or the end of service, as allowed under the Issuer's equity incentive plan.
F2 These restricted stock units do not have an expiration date.
