        <footnote id="F1">The shares subject to this option were determined based on the Black-Scholes value of the vested PDL options that Mr. Cross forfeited as a result of the spin-off of Facet Biotech in December 2008.  These options were immediately vested at the time of grant. The Company's intent to grant these options, the expected terms of these grants and the method by which the number of shares was to be calculated were disclosed in the Re-Engagement Grants section of the Information Statement attached to the Registration Statement on Form 10 the Company originally filed with the Securities and Exchange Commission on August 13, 2008 in conjunction with the spin-off.</footnote>
