        <footnote id="F5">This transaction relates to the grant of Performance Stock Units (&quot;PSUs&quot;), which are performance-based equity awards.  The number of underlying shares of common stock of Redwood Trust, Inc. (&quot;Common Stock&quot;) that vest and that the recipient becomes entitled to receive at the time of vesting will generally range from 0% to 200% of a target number of PSUs granted, contingent on the achievement of a pre-established performance metric (with the target number of PSUs granted being adjusted to reflect the value of any dividends on Common Stock paid during the vesting period). Vesting of these PSUs will generally occur at the end of three years (on November 30, 2013) based on three-year total stockholder return.  Please refer to Item 5.02(e) of the Current Report on Form 8-K filed on December 2, 2010 by Redwood Trust, Inc. for a description of the terms of these PSUs, which Item 5.02(e) qualifies, in its entirety, the description set forth in this footnote (5) and footnote (7) below.</footnote>
