        <footnote id="F1">Each deferred stock unit (&quot;DSU&quot;) represents a right to receive one share of Louisiana-Pacific Corporation (&quot;LP&quot;)</footnote>
        <footnote id="F2">Pursuant to the LP Non-Employee Directors Compensation Plan, non-employee directors who earn quarterly cash retainer fees for their services on LP's Board of Directors may elect to exchange their quarterly cash fees for an award of DSUs.  The number of DSUs so acquired is calculated by dividing the deferred cash retainer amount by the closing price for LP's common stock on the date the cash retainer is payable.</footnote>
        <footnote id="F3">DSUs are to be settled in shares of common stock after the reporting person's termination of services as a director or a change in control.</footnote>
