NXG Cushing Midstream Energy Fund

The Funds have retained Georgeson LLC to assist in the solicitation of proxies at an estimated cost of $70,000 for SRV and $60,000 for NXG, plus any out-of-pocket expenses.

The costs and expenses of preparing the proxy statement and soliciting proxies in connection with Proposal 1 will be borne by the Funds. Each Fund pays a pro rata portion (based on respective net assets) of such costs and expenses.

The Adviser will bear the costs and expenses of preparing the proxy statement and soliciting proxies in connection with Proposal 2 and any other costs of the Funds associated with the Transaction. The allocation of costs and expenses attributable to Proposal 1 and Proposal 2 will be approved by the Board. Costs and expenses incurred by the Adviser are not subject to recoupment from the Funds.

The Funds’ officers and employees of the Adviser (none of whom will receive additional compensation therefor) may solicit proxies by telephone, mail, e-mail and personal interviews. Brokerage houses, banks and other fiduciaries may be requested to forward proxy solicitation material to their principals to obtain authorization for the execution of proxies, and will be reimbursed by the Funds for such out-of-pocket expenses.
