(1) This transaction was made by a fund that is not, itself, a 10% owner of the issuer's securities. The reporting person is reporting this transaction because he is the managing member of the fund's general partner and thus may be deemed an indirect beneficial owner of the fund's holdings. When these holdings are aggregated with the reporting person's other indirect holdings of this issuer's securities, he may be deemed an indirect beneficial owner of 10% or more of the issuer's securities.
(2) This transaction was made by a fund that is not, itself, a 10% owner of the issuer's securities.

When these holdings are aggregated with the reporting person's other indirect holdings of this issuer's securities, he may be deemed an indirect beneficial owner of 10% or more of the issuer's securities.
