Hambrecht & Quist Capital Management LLC ("HQCM") disclaims any beneficial interest in the shares reported in this Schedule 13G. Moreover, HQCM is of the view that the client accounts that it manages are not acting as a "group" for purposes of Section 13(d) under the Securities and Exchange Act of 1934 (the "1934 Act") and that it and such clients are not otherwise required to attribute to each other the "beneficial ownership" of securities "beneficially owned" under Rule 13d-3 promulgated under the 1934 Act. Therefore, HQCM is of the view that the shares held in such accounts should not be aggregated for purposes of Section 13(d). However, HQCM is making this filing on a voluntary basis as if all the shares are beneficially owned by HQCM on a joint basis. 1,048,202 shares of Common stock beneficially owned 10.66% of Common 1,048,202 sole voting power (i) and sole dispositive power (iii) ITEM 5.
