Explanation of Responses:
1. The filing of this Form 4 shall not be construed as an admission that Swank Capital, L.L.C. ("Swank Capital"), Swank Energy Income Advisors, L.P. ("Income Advisors"), The Cushing MLP Opportunity Fund I, LP ("Opportunity Fund") or Jerry V. Swank ("Mr. Swank") is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, the beneficial owner of any of the common units of Rio Vista Energy Partners LP ("Common Units") held by Opportunity Fund, in the total return equity swap agreement entered into by The Cushing Fund (Offshore), Ltd. ("Cushing Offshore") or in a personal account of Mr. Swank. Pursuant to Rule 16a-1, Swank Capital, Income Advisors, Opportunity Fund and Mr. Swank disclaim such beneficial ownership.
2. Swank Capital holds indirectly 405,486 Common Units through Income Advisors, of which Swank Capital is the general partner, which in turn holds Common Units through the account of Opportunity Fund.

3. Cushing Offshore was a party to a total return equity swap agreement with respect to shares of Common Units. Income Advisors is the investment manager of Cushing Offshore and receives an allocation of net profits and an asset based fee from Cushing Offshore. Swank Capital is the general partner of Income Advisors and Mr. Swank owns a limited partner interest in Income Advisors. Mr. Swank is the manager of Swank Capital, and, in addition, owns shares of Cushing Offshore. As a result of the sale of shares of Common Units on January 16, 2008, Cushing Offshore no longer holds any shares of Common Units.
4. Mr. Swank holds 674 Common Units in a personal account.
5. For clarification purposes, the sale of 6,568 Common Units by Swank MLP Convergence Fund, LP on July 16, 2007, as reported in a Form 4 filed by the Reporting Persons on July 17, 2007, reduced the amount of Commun Units held by Swank MLP Convergence Fund, LP to 0.
