Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On February 5, 2007, in conjunction with the Issuer's initial public offering (the "IPO"), Enterprise Products Operating L.P. ("EPOLP"), a wholly owned subsidiary of Enterprise Products Partners L.P., contributed certain assets to the Issuer in exchange for 7,301,571 common units representing limited partnership interests of the Issuer. In conjunction with the issuance of these common units, EPOLP gave the issuer an option to buy up to 1,950,000 common units at a price per unit equal to the net proceeds per unit of the issuer, after discounts and commissions, in the IPO, if the underwriters exercised their option to purchase additional common units. On February 5, 2007, in conjunction with the IPO, the net proceeds from the exercise of the underwriters' option to purchase additional common units were used to redeem 1,950,000 comon units at a price of $19.74 per common unit.
(2) The reporting person does not benefically own any securities of the Issuer whether directly or indirectly.
