Re:    Management Fee for the Quarter Ended December 31, 2017
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 such
agreement has been, 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, effective
as of December 31, 2017, to clarify the application of the Management Fee
provisions set forth in Section 8(a) of the Management Agreement to the
Company’s December 29, 2017 acquisition of the remaining 18.95% interest in
Pinedale Corridor, LP, previously held by the Prudential Insurance Company of
America. This letter documents that the Manager has proposed, and the Company
has agreed, that solely for the purpose of calculating the quarterly Management
Fee due as of December 31, 2017, the definition of “Managed Assets” set forth in
Section 8(a) of the Management Agreement shall be applied in a manner that
continues to reduce Managed Assets by the initial invested value of the
non-controlling interest in Pinedale Corridor, LP. This letter in no way
supersedes our May 9, 2016 letter agreement (effective March 31, 2016)
concerning the Management Fee calculation.

The purpose of this clarification is to ensure the application of Section 8(a)
of the Management Agreement to the acquisition of the remaining 18.95% interest
in Pinedale Corridor, LP, in the manner that is most fair and equitable to the
Company’s stockholders. 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.

 
 
Very truly yours,
