        <footnote id="F1">Thomas J. Quinlan has been awarded restricted stock with a value of $4,705,000 by LSC Communications, Inc. (&quot;LSC&quot;).  The number of restricted shares awarded will be based on a twenty trading day value weighted average price of LSC common stock following the date of grant.</footnote>
        <footnote id="F2">Reflects ownership of LSC common stock obtained in connection with the spinoff of LSC by R. R. Donnelley &amp; Sons Company (&quot;RRD&quot;) and the distribution of one (1) share of LSC common stock for every eight (8) shares of RRD common stock held prior to the spinoff, which was effective on October 1, 2016 (the &quot;Spinoff&quot;).  Does not include restricted stock units, which are reflected as beneficially-owned and reported as shares of common stock. The number of restricted stock units over LSC common stock has not yet been determined, as restricted stock units and performance share units over RRD common stock outstanding prior to October 1, 2016 will be converted into restricted stock units over the LSC common stock to give effect to the Spinoff.</footnote>
        <footnote id="F3">(Continued from footnote 2) The number of restricted stock units over the DFS common stock will be determined after the date hereof pursuant to an equitable adjustment in the Separation and Distribution Agreement, dated as of September 14, 2016, by and among RRD, LSC and Donnelley Financial Solutions, Inc. (&quot;DFS&quot;).  Does not reflect ownership of options over LSC common stock, which would be reported in Table II, which were received by virtue of ownership of stock options over RRD common stock. These exercisable stock options to purchase shares of RRD common stock will convert into options to purchase LSC common stock. The number of stock options over RRD common stock, LSC common stock and DFS common stock will be determined after the date hereof pursuant to an equitable adjustment in the Separation and Distribution Agreement.  The Reporting Person will amend this Form 4 when such information is available.</footnote>
