        <footnote id="F1">Each phantom stock unit under the company's non-qualified deferred compensation plan as reported is generally the economic equivalent of one share of Caterpillar Inc. common stock.</footnote>
        <footnote id="F2">This total includes 6 shares that were credited to the reporting person's account under the Supplemental Deferred Compensation Plan (&quot;the Plan&quot;) at a price per share of $306.45 and 6 shares that were contributed to the reporting person's account pursuant to the terms of the Plan for no consideration.</footnote>
        <footnote id="F3">The phantom stock units are to be settled for 100% in cash upon the reporting person's retirement or separation from service.</footnote>
        <footnote id="F4">Includes dividends accrued. Moreover, phantom stock units represent interests in an unfunded unitized company stock fund comprised of stock and cash, and therefore the number of phantom stock units the reporting person is deemed to own may change between any given dates due to differences in the percentages of cash and stock in the unitized fund on those dates.</footnote>
