Pursuant to, and subject to the terms and conditions of, a management agreement between GI GP and GIP Management, GIP Management has sole voting and investment power over the securities held by the GIP Partnerships. Each of GIP Investors, GIP Management and GI GP may be deemed to indirectly beneficially own these securities held by the GIP Partnerships, but disclaim beneficial ownership except to the extent of their pecuniary interest therein.
( 3)	Pursuant to a Contribution, Conveyance and Assumption Agreement, which the GIP Partnerships, the Issuer and the other parties thereto entered into prior to the time the Securities and Exchange Commission declared the Issuer's Registration Statement on Form S-1 (Registration No. 333-164905) (the "Registration Statement") effective, the GIP Partnerships will exchange their existing ownership interests in an affiliate of the Issuer for approximately 20,725,561 Common Units and 34,538,061 Subordinated Units upon the closing of the Issuer's initial public offering, and up to an additional 3,187,500 Common Units in the event the underwriter's over-allotment option is not exercised, and the Issuer will redeem for nominal consideration the current 50% limited partnership interest in the Issuer held by the GIP Partnerships. (Continued in footnote 4).
( 4)	If the Issuer increases or decreases the number of common units to be sold to the public through the underwriters, the Issuer will correspondingly decrease or increase the number of common units to be issued to the GIP Partnerships, respectively.
( 5)	The Subordinated Units will convert into Common Units on a one-for-one basis at the end of the subordination period described in the Registration Statement.
