        <footnote id="F1">Each phantom stock unit is the economic equivalent of one share of Fluor common stock.</footnote>
        <footnote id="F2">These phantom units were acquired under the Fluor Corporation 409A Director Deferred Compensation Program (the &quot;Program&quot;) through the crediting of dividends and are to be settled in cash.  Distributions will be made, at the election of the reporting person, either (i) in the distribution year specified by the reporting person or (ii) upon the reporting person's termination of service as a director, death or disability, in a single lump sum payment or annual installment payments over a period of two to ten years.  The reporting person may transfer the phantom units into an alternative investment at any time.  However, unvested units granted as matching contributions under the Program shall be forfeited by the reporting person to the extent attributable to the transferred units.</footnote>
