        <footnote id="F1">These securities are held directly by Orphan Fund, L.P. (&quot;Orphan Fund&quot;), Nanocap Qualified Fund, L.P. (&quot;Nanocap Qualified&quot;) and Nanocap Fund, L.P. (&quot;Nanocap Fund&quot;), U.S. investment limited partnerships (collectively, the &quot;Partnerships&quot;), none of which, for Section 16 purposes, is itself the beneficial owner of more than 10% of the issuer's common stock.  307,710 shares of common stock reported on this Form 3 are beneficially held by Orphan Fund, 106,077 shares are beneficially held by Nanocap Qualified and 73,870 shares are beneficially held by Nanocap Fund.  (see footnote 2).</footnote>
        <footnote id="F2">(continued from footnote 1).  Stephens Investment Management, LLC (&quot;SIM&quot;) is the general partner and investment manager of each of the Partnerships.  Paul H. Stephens, P. Bartlett Stephens and W. Bradford Stephens are each managing members and minority owners of SIM and each also holds limited partnership interests in Nanocap Fund.  Paul H. Stephens also holds a limited partnership interest in Orphan Fund.   Each of SIM, Paul H. Stephens, P. Bartlett Stephens, W. Bradford Stephens and each Partnership expressly disclaims beneficial ownership in these securities, except to the extent of their respective pecuniary interests therein.</footnote>
        <footnote id="F3">Although none of the Partnerships is itself the beneficial owner of more than 10% of the issuer's common stock, SIM and the other reporting persons may be deemed to beneficially own the securities owned by the Partnerships insofar as they may be deemed to have the power to direct the voting or disposition of such securities.  The reporting persons have elected therefore to file this Form 3 to report the Partnerships' holdings on an aggregate basis.  The filing of this Form 3 should not, however, be deemed an admission by any of the reporting persons that the reporting persons and/or the Partnerships form a group within the meaning of Rule 13d-5(b)(1) and Rule 16a-1(a)(1).</footnote>
