FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT

This First Amendment to Amended and Restated Credit Agreement (the “Amendment”) is made effective as of July 10, 2014, by and among TORTOISE ENERGY INFRASTRUCTURE CORPORATION, a Maryland corporation (the “Borrower”); U.S. BANK NATIONAL ASSOCIATION, a national banking association, BANK OF AMERICA, N.A., and THE BANK OF NOVA SCOTIA (each a “Bank” and, collectively, the “Banks”); and U.S. BANK NATIONAL ASSOCIATION, a national banking association, as the lender for Swingline Loans (in such capacity, the “Swingline Lender”), as agent for the Banks hereunder (in such capacity, the “Agent”), and as lead arranger hereunder (in such capacity, the “Lead Arranger”). Capitalized terms used and not defined in this Amendment have the meanings given to them in the Credit Agreement referred to below.

Preliminary Statements

(a) The Banks and the Borrower are parties to an Amended and Restated Credit Agreement dated as of June 23, 2014 (as the same may be amended, renewed, restated, replaced, consolidated or otherwise modified from time to time, the “Credit Agreement”).

(b) The Borrower has requested certain modifications to the Credit Agreement and the Banks are willing to make such modifications, subject, however, to the terms, conditions and agreements set forth below.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Modification to Definition of “Permitted Liens”. The following phrase is added to the end of the definition of “Permitted Liens” as set forth in Section 1.1 of the Credit Agreement:

“, and (6) Liens arising in connection with customary fees and expenses and other payments due to the Borrower’s custodian in the ordinary course of business.”

2. Deletion of Defined Term “Encumbered Property”. The defined term “Encumbered Property” as set forth in Section 1.1 of the Credit Agreement is hereby deleted in its entirety.

3. Modification to Section 6.2(a) (Covenant Regarding Liens). Section 6.2(a) of the Credit Agreement is deleted in its entirety and is replaced with the following:

(a) Liens. The Borrower shall not create or suffer to exist any Lien on or with respect to any of its properties, whether the Borrower owns or has an interest in such property on the Closing Date or at any time thereafter, except for Permitted Liens.

4. Modification to Section 7.4 (Ranking of Loans; Compliance with Investment Company Act of 1940). Section 7.4 of the Credit Agreement is hereby deleted in its entirety and is replaced with the following:

7.4 Ranking of Loans; Compliance with Investment Company Act of 1940. Notwithstanding anything herein or in the other Credit Documents to the contrary, the Loans and all other obligations of the Borrower hereunder or under the other Credit Documents shall rank pari passu in all respects with the other senior securities representing indebtedness of the Borrower. It is the intention of the Agent, the Banks and the Borrower to comply with the provisions of the 1940 Act. If any term, condition or other provision in this Agreement or any of the other Credit Documents is deemed by the Securities and Exchange Commission or any court to render any Loan or other obligation incurred under any of the Credit Documents a separate "class of senior securities representing indebtedness," for purposes of Section 18(c) of the 1940 Act, and to have preferential rights over any other senior securities representing indebtedness of the Borrower in violation of Section 18(c) of the 1940 Act, the Agent, the Banks and the Borrower agree to diligently and in good faith negotiate an amendment to the applicable Credit Documents so as to comply with Section 18(c) of the 1940 Act provided that such amendment does not impair the Agent’s and/or the Banks’ fundamental economic rights under the Credit Documents.

5. Reaffirmation of Credit Documents. The Borrower reaffirms its obligations under the Credit Agreement, as amended hereby, and the other Credit Documents to which it is a party or by which it is bound, and represents, warrants and covenants to the Agent and the Banks, as a material inducement to the Agent and each Bank to enter into this Amendment, that (a) the Borrower has no and in any event waives any, defense, claim or right of setoff with respect to its obligations under, or in any other way relating to, the Credit Agreement, as amended hereby, or any of the other Credit Documents to which it is a party, or the Agent’s or any Bank’s actions or inactions in respect of any of the foregoing, and (b) all representations and warranties made by or on behalf of the Borrower in the Credit Agreement and the other Credit Documents are true and complete in all material respects on the date hereof as if made on the date hereof (except to the extent such representations and warranties specifically relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects on and as of such earlier date).

6. Conditions Precedent to Amendment. Except to the extent waived in a writing signed by the Agent and delivered to the Borrower, the Agent and the Banks shall have no duties under this Amendment until the Agent shall have received fully executed originals of each of the following, each in form and substance satisfactory to the Agent:
