1. Each restricted stock unit represents a contingent right to receive one share of Mirant Corporation common stock.
2. The restricted stock units vest 100% on 5/12/10. Delivery of the vested shares will be deferred until termination.
3. In previous Section 16 filings, 1,015 shares of restricted stock that are not derivative securities were included in the total number of restricted stock units. These shares have been reported correctly in Table I as non-derivative securities in a previous Section 16 filing and should not be included in the total and accordingly, have been removed in this filing.
