Leaving share incentive scheme - capital gains tax exposure

I have changing employer so am obliged to close out my share incentive plan with my current employer within 30 days of leaving the company, and either sell all shares, or transfer to a ordinary brokerage account. I have reviewed some very old documentation from HMRC that references tax years several years out of date, so am looking for specific and clear clarification on the two points below. Please clarify: 1) If I sell total balance of the shares from the share incentive plan before it closes (within 30 days of leaving the company), these will not be subject to capital gains tax - correct? So do not need to be declared as a capital gain in a self-assessment - correct? 2) If I transfer the shares out of the share incentive plan into an ordinary brokerage account, and sell at a later date, the capital gains will be calculated from the final market price at which the shares are sold, against the market price at the point at which the shares were transferred from the share incentive plan to the ordinary brokerage account - correct?
