 One-third of the units comprising the award vest on the fifth anniversary of the date of grant and the remaining two-thirds
 of the units vest in equal increments on each of the first, second, third, fourth and fifth anniversaries of the date of
 grant (each, a vesting date) and are subject to payment within 75 days following each such vesting date.  Each unit
 represents a right to receive one share of Common Stock or an amount equal to the market value of the Common Stock
 underlying the vested award on the applicable vesting date.  Payment may be made in cash, shares of Common Stock or a
 combination thereof.  On February 4, 2008, the second vesting of this restricted stock award was paid in shares.  Shares
 were withheld to satisfy applicable tax withholding obligations.</footnote>
