Explanation of Responses:

( 1 )Such partnership units are held by a nominee for a Guernsey unit trust in which Lord Rothschild and certain of his family interests hold, directly or indirectly, units. ( 2 )Pursuant to Rule 16a-1(a)(2) under the Securities Exchange Act of 1934, as amended (the "Act"), Lord Rothschild may be deemed to be the beneficial owner of certain of these partnership units. This Statement, however, shall not be deemed an admission that he is, for purposes of Section 16 of the Act or otherwise, the beneficial owner of any of such partnership units and, even if deemed the beneficial owner for purposes of Section 16 of the Act, he disclaims such beneficial ownership except to the extent of his pecuniary interest in the securities. ( 3 )This amendment is being filed to reflect the final number of partnership units that the nominee was able to purchase on behalf of the unit trust in connection with the initial public offering of the partnership units.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
