Explanation of Responses:

1. The securities reported on this filing are held in the accounts of certain unregistered investment companies over which the Reporting Person has investment discretion by virtue of the Reporting Person's position in the general partners of these unregistered investment companies. The Reporting Person in turn has a pecuniary interest in the securities held by said unregistered investment companies equal to his portion of the incentive allocation potentially made to the general partners of said entities each year in unaffiliated capital accounts in said entities, plus his capital accounts in said entities.

Remarks:

++ The Reporting Person, the unregistered investment companies and the general partners affirmatively disclaim being a "group" for purposes of Section 16 of the Securities Exchange Act of 1934, as amended.
