        <footnote id="F1">Settlement of performance stock unit, vested on 2/23/15, was previously reported, but the settlement of the restricted stock unit was inadvertantly left off of the Form 4.  This amendment reflects the vesting of the restricted stock unit, the award of which was orginally reported on Table II of a Form 5 filed on 2/12/13.</footnote>
        <footnote id="F2">Each restricted stock unit converted to one share of WNC common stock as of date of vesting on 2/23/2015.</footnote>
