|  | You may receive materials from Saba Capital Management, L.P. ("Saba Capital") asking you to vote on a gold card or voting instruction form. Saba Capital is a dissident hedge fund with a history of running self-interested campaigns that derail a fund's ability to enhance value for long-term stockholders like you. |
| ![LOGO](g490680snap15.jpg) | **We urge you NOT to return any gold proxy card that you receive, as that vote will not count as a vote in support of the Fund's Board. If you vote your shares more than once, only your latest-dated proxy card counts.** |
|  | Your Board has extensive experience overseeing energy MLP closed-end funds and a track record of delivering value to you. On the other hand, Saba Capital's nominee is an employee of Saba Capital with little to no experience overseeing energy MLPs. Further, Saba Capital has indicated that, if elected, its nominee would propose a liquidity event that could derail the Fund's ability to execute its proven strategy and lead to negative tax implications. |
|  | **Protect the Value of Your Investment.**<br> **Vote on the Enclosed WHITE Proxy Card Today** |
|  | Whether or not you plan to attend the Annual Meeting, you have an opportunity to protect the value of your investment by voting on the WHITE Proxy Card "FOR" the Fund's nominee. |
