REGISTRATION STATEMENT

Explanatory Note (page 1)

1.     Please add the bulleted disclosure below, if applicable, in bold and if
the Company makes
additional offerings of its Shares in the future, an investor may be required
to make additional
purchases of the Company   s Shares on one or more dates to be determined by
the Company.

   x   The Company intends to invest primarily in privately held companies for
which little
       public information exists and which are more vulnerable to economic
downturns and
       substantial variations in operating results.

   x   The privately held companies, below investment grade securities (   junk
   bonds) and real
       estate in which the Company invests are difficult to value and will
generally be illiquid.

   x   Our distributions may be funded from unlimited amounts of offering
proceeds or
       borrowings, which may constitute a return of capital and reduce the
amount of capital
       available to us for investment. Any capital returned to you through
distributions will be
       distributed after payment of fees and expenses.

   x   If the Company makes additional offerings of its Shares in the future,
an investor may be
       required to make additional purchases of the Company   s Shares on one
or more dates to
       be determined by the Company.

2.      Given the length of the Risk Factors section, please include in the

that is no more than
two pages summarizing the principal risk factors. See Item 105(b) of Regulation
S-K.
