Re:    Management Fee Under Management Agreement for CorEnergy Infrastructure
Trust, Inc.

Ladies and Gentlemen:

Reference is made to that certain Management Agreement, dated as of May 8, 2015
and effective as of May 1, 2015, by and between CorEnergy Infrastructure Trust,
Inc., a Maryland corporation (the “Company”), and Corridor InfraTrust
Management, LLC, a Delaware limited liability company (the “Manager”) (as may be
further amended, restated, supplemented or otherwise modified from time to time,
the “Management Agreement”). Capitalized terms used and not defined herein are
used as defined in the Management Agreement. The Company and the Manager have
entered into this Letter Agreement to modify the application of the Management
Fee provisions set forth in Section 8(a) of the Management Agreement to the
value of the Black Bison Loans and the Black Bison Warrant (each as defined
below), effective as of the Company’s September 30, 2015 balance sheet date.

On March 13, 2014 the Company’s wholly-owned subsidiary, Corridor Bison, LLC
(“Corridor Bison”) entered into a Loan Agreement with Black Bison WS, pursuant
to which Corridor Bison agreed to loan Black Bison WS up to $11.5 million (the
“Black Bison WS Loan”). On July 24, 2014, Corridor Bison entered into an
amendment increasing the maximum size of the Black Bison WS Loan to $12 million
and the Company’s subsidiary, CorEnergy BBWS, Inc. entered into a TRS Loan
Agreement, pursuant to which CorEnergy BBWS agreed to loan Black Bison WS up to
$3.3 million (together with the Black Bison WS Loan, the “Black Bison Loans”).
CorEnergy BBWS also holds an Amended and Restated Warrant to purchase a number
of equity units representing approximately 18.72 percent of the outstanding
equity of Black Bison Intermediate Holdings, LLC (the “Black Bison Warrant”).

Due to reduced drilling activity in Black Bison WS’s area of operations, the
Company determined during the preparation of its financial statements for the
period ended September 30, 2015 that it is necessary to record a provision for
loan loss to write the Black Bison Loans down to a current value of $7,690,000,
and to write off the entire book value of the Black Bison Warrant.

This letter documents that the Manager has recommended, and the Company has
agreed, that solely for the purpose of calculating the quarterly Management Fee
on and after the Company’s September 30, 2015 balance sheet date, that portion
of the Management Fee attributable to the Company’s investment in the Black
Bison Loans and the Black Bison Warrant shall be based on the estimated net
realizable value of (which shall not exceed the amount invested in) such
investments as of the end of the quarter for which the Management Fee is to be
calculated.

The Company and the Manager mutually acknowledge and agree that this
modification to the calculation of the Management Fee due as of September 30,
2015 represents a discretionary action on the part of the Manager that is not
required under the terms of the Management Agreement and that, except as
specifically set forth herein, all other provisions of the Management Agreement
shall remain in full force and effect and shall not be affected by this Letter
Agreement. Please acknowledge your agreement to the foregoing by signing this
Letter Agreement as indicated below.
