[1] Such shares were withheld to cover the exercise price of stock options, if applicable, and required tax withholdings.

[2] In certain situations, U.S. Cellular withholds shares that are issuable upon the exercise of stock options or the vesting of restricted shares to cover, and with a value equivalent to, the exercise price and/or the amount of taxes required to be withheld from the stock award holder at the time of the exercise or vesting.  U.S. Cellular then pays the amount of the required tax withholdings to the taxing authorities in cash.
