        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of issuer's common stock and/or the cash value thereof.  The restricted stock units vested pursuant to the Amended and Restated Agreement and Plan of Merger by and between The Ryland Group, Inc. and Standard Pacific Corp. dated as of June 14, 2015 (the &quot;merger agreement&quot;).  Pursuant to the merger agreement, The Ryland Group, Inc. merged with and into Standard Pacific Corp., with Standard Pacific Corp. continuing as the surviving corporation under the name CalAtlantic Group, Inc.  Immediately prior to the effective time of the merger, each restricted stock unit was settled in a share of Ryland common stock, less any applicable tax withholding.</footnote>
        <footnote id="F2">Reflects settlement of long-term incentive plan (&quot;LTIP&quot;) awards.  The LTIP awards vested (at the target level) pursuant to the merger agreement.  Immediately prior to the effective time of the merger, LTIP awards were settled in shares of Ryland common stock, less any applicable tax withholding.</footnote>
        <footnote id="F3">Disposed of pursuant to the merger agreement.  At the effective time of the merger, each share of Ryland common stock issued and outstanding immediately prior to the effective time of the merger was converted into and became exchangeable for 1.0191 validly issued, fully paid and non-assessable shares of common stock of CalAtlantic Group, Inc.</footnote>
        <footnote id="F4">Pursuant to the merger agreement, each option to purchase shares of Ryland common stock was converted into an option to acquire shares of CalAtlantic Group, Inc. common stock on the same terms and conditions as were applicable under such option as of immediately prior to the merger.  The number of shares of CalAtlantic Group, Inc. common stock underlying each converted Ryland option was determined by multiplying the number of shares of Ryland common stock subject to such option immediately prior to the completion of the merger by the exchange ratio of 1.0191, and rounding down to the nearest whole share.</footnote>
