        <footnote id="F1">Each director is granted $50,000 of common stock of Kraton Performance Polymers, Inc. for their services on the Board. The price of the stock is based upon the average of the high and low prices of the common stock of Kraton Performance Polymers, Inc. (?KPP Shares?) as reported on the New York Stock Exchange on January 28, 2010. Pursuant to contractual undertakings by the Reporting Person, the Reporting Person is holding these shares for the benefit of J.P. Morgan Partners (BHCA), L.P.</footnote>
        <footnote id="F2">The amounts shown represent the beneficial ownership of the Issuer's securities by (i) JPMP BHCA, (ii) J.P. Morgan Partners Global Investors, L.P. (&quot;J.P. Morgan Global&quot;), (iii) JPMP Global Funds/Kraton A, L.P. (&quot;JPMP Kraton A&quot;), (iv) J.P. Morgan Partners Global Investors (Cayman) L.P. (&quot;JPMP Cayman&quot;), (v) J.P. Morgan Partners Global Investors (Cayman) II, L.P. (&quot;JPMP Cayman II&quot;), (vi) JPMP Global Fund/Kraton, L.P. (&quot;JPMP Kraton&quot;), (vii) J.P.

Morgan Partners Global Investors (Selldown) II, L.P. (&quot;JPMP Selldown II?) and (x) JPMP Global Fund/Kraton/Selldown II L.P (&quot;JPMP Kraton Selldown II&quot;), and together with J.P. Morgan Global, JPMP Kraton A, JPMP Cayman, JPMP Cayman II, JPMP Kraton, JPMP Selldown, JPMP Kraton Selldown, JPMP Selldown II, JPMP Kraton S
elldown II, the &quot;Global Funds&quot;). (Continue to Footnote 3)</footnote>
        <footnote id="F3">3.	The Reporting Person is a limited partner of JPMP Master Fund Manager, L.P. (&quot;JPMP MFM&quot;). JPMP MFM is the general partner of JPMP BHCA and a limited partner of JPMP Global Investors, L.P. (&quot;JPMP Global Investors&quot;), the general partner of the Global Funds. The actual pro rata portion of beneficial ownership of any KPP Shares that may be deemed attributable to the Reporting Person is not readily determinable because it is subject to several variables, including the internal rate of return and vesting of interests within JPMP BHCA, JPMP MFM, JPMP Global Investors and the Global Funds. Mr. O'Brien disclaims beneficial ownership of the securities to the extent it exceeds his pecuniary interest therein.</footnote>
