Note: Past performance is not indicative of future results. Past performance as well as future results are dependent on a variety of factors, including prevailing market conditions and investment availability, which vary over time. For example, returns will appear substantially higher if the beginning of the performance calculation period begins on a day when the relevant markets were under severe distress.

(1) Net returns are reflected on a calendar year basis.

(2) Net total return based on Net Asset Value ("NAV") reflects the change in ending NAV per share plus distributions per share
paid during the period, assuming distributions were reinvested at the most recent calendar quarter NAV, excluding any discounts, divided
by the beginning NAV per share.

(3) 2011 return includes adjusted opening NAV of $18.40 per share, post IPO offering.

(4) Net total return based on NAV for Class A, I, and L Share investors reflects the change in ending NAV per share plus distributions
per share paid during the period assuming distributions were reinvested at the most recent monthly NAV, including any discounts, divided
by the beginning NAV per share.

(5) Net total return based on a day one full fee-paying investor.

(6) Net Internal Rate of Return ("IRR") is calculated on the fund as a whole, excluding the managing member and is presented
on an annualized basis, except where explicitly noted otherwise. IRRs for short periods of time are affected by significant cash-flows
over such periods, which did occur in some periods above. The actual dollars made, since inception of the fund, as a ratio of the dollars
distributed plus the most recent calendar quarter NAV divided by the dollars contributed (known as the multiple of invested capital or
"MOIC") are presented below for the private funds where net IRRs are presented above.

Private Fund #2: 1.48

Private Fund #3: 1.22

Private Fund #3a: 1.34

Private Fund #3b: 1.27

Private Fund #3c: 1.50

(7) Net IRRs are presented on a de-annualized basis as these periods represent less than one full calendar year.

(8) Cumulative Inception To Date ("ITD") represents the respective funds' net cumulative total returns, or cumulative IRR for
certain funds as noted above, where cumulative IRR compounds the annualized IRR by the number of years from fund inception through the
most recent calendar quarter end, to produce a hypothetical ITD net cumulative total return. The net IRRs in the table above and the MOIC
in footnote 6 represent the actual fund performance data for Private Funds #2 to #3c.
