| (1) | Prior to December 4, 2008, 8,841,193 common units of the Issuer ("Common Units") were owned directly by MGG Midstream Holdings, L.P. ("MGG MH"), which was a member of a "group" (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) that included, among other entities, Madison Dearborn Capital Partners IV, L.P. ("MDCP IV"), Madison Dearborn Partners IV, L.P. ("MDP IV") and Madison Dearborn Partners, LLC ("MDP LLC"). Members of this group filed joint Form 4s with the Securities and Exchange Commission. On December 4, 2008, as described in a Form 4 filed by MGG MH with the Securities and Exchange Commission, MGG MH distributed all of the Common Units owned by it to its general partner and limited partners on a pro rata basis, and its general partner in turn distributed the Common Units received in such distribution to its members on a pro rata basis. (Continue to footnote 2) |
| (2) | As a result of these distributions, MDCP IV became the direct owner of 4,168,133 Common Units. On March 20, 2009, MDCP IV distributed all of the Common Units owned by it to its general partner and limited partners on a pro rata basis. As a result of this distribution, MDCP IV no longer owns any Common Units (nor does it have any pecuniary interest in any Common Units reported on this Form 4). MDCP IV and MDP IV are jointly filing this Form 4. The reporting persons disclaim beneficial ownership of the reported securities except to the extent of their pecuniary interest therein, and this report shall not be deemed an admission that the reporting persons are beneficial owners of the reported securities for purposes of Section 16 or for any other purpose. Patrick C. Eilers, a limited partner of MDP IV, is a director of the Issuer. |
| (3) | On March 20, 2009, MDP IV (the general partner of MDCP IV) became the direct owner of 941,148 Common Units as a result of the distribution described in Footnote (2) above. Following such distribution, MDP IV further distributed 101,739 Common Units to its general partner and limited partners on a pro rata basis and MDP IV retained 839,409 Common Units. A limited partner committee of MDP IV composed of John A. Canning, Paul J. Finnegan and Samuel M. Mencoff has the power, acting by majority vote, to vote or dispose of the Common Units directly held by MDP IV. Messrs. Canning, Finnegan and Mencoff each hereby disclaims any beneficial ownership of any Common Units over which MDP IV has voting and dispositive power. Due to this limited partner committee of MDP IV, MDP LLC no longer reports beneficial ownership of Common Units which may be deemed to be beneficially owned by it. |
