Explanation of Responses:
(1) This transaction was executed in multiple trades at prices ranging from $15.51 per unit to $16.00 per unit. The price reported above reflects the weighted average purchase price. Note that due to field restrictions in Table 1, Column 4, the last decimal place does not appear. The total weighted average purchase price is actually $15.81409. Upon request from the Securities and Exchange commission, the issuer or a unitholder of the issuer, full information regarding the number of units purchased at each separate price will be made available.
(2) The total amount of securities reported as beneficially owned reflects the transfer, since Mr. Greehey's last Form 4, of 30,000 Common Units from direct ownership to indirect ownership through a family limited partnership, which transfer was exempt from Section 16 of the Exchange Act pursuant to Rule 16a-13 thereunder.
