Restricted Stock Unit Awards
The Compensation Committee will determine the material terms of restricted stock unit awards, including the vesting schedule, the price (if any) to be paid by the recipient in connection with the award and any transferability restrictions or other conditions applicable to the award.
A restricted stock unit award is similar in nature to a restricted stock award except that in the case of a restricted stock unit, no shares of Common Stock are actually transferred to a holder until a later date, as specified in the applicable award agreement. Accordingly, a holder of a restricted stock unit will not have the rights of a stockholder of EOG. Each restricted stock unit will have a value equal to the fair market value of a share of our Common Stock. All dividends and distributions (whether in cash, stock or otherwise) on unvested restricted stock units will not be paid but will be credited for the future benefit of the recipient. At such time as vested restricted stock units are paid, all accumulated dividends and distributions attributable to the vested restricted stock unit (without interest) will be paid in cash, shares of our Common Stock or such other form as we determine. Any dividends and distributions on non-vested restricted stock units will be forfeited in the same manner and at the same time as the respective restricted stock units to which they are attributable are forfeited.
Payment under a restricted stock unit award will be made in shares of our Common Stock and will be made either (i) by a date that is no later than two and one-half months after the end of the fiscal year in which the restricted stock unit is no longer subject to a substantial risk of forfeiture (as that term is defined in the 2008 Plan) or (ii) at a time that is permissible under Section 409A of the Code.
