RECITALS

I. Each term that is defined in the Credit Agreement and not herein defined has the meaning ascribed thereto by the Credit Agreement when used herein.

II. The Borrower desires an amendment to the Credit Agreement upon the terms and conditions herein contained, and all Lenders have agreed thereto upon the terms and conditions herein contained.

AGREEMENTS

Accordingly, in consideration of the Recitals and the covenants, conditions and agreements hereinafter set forth, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

1. Section 6.16 of the Credit Agreement and Exhibit D to the Credit Agreement are each hereby amended by replacing each reference to “1940 Act” contained therein with “Investment Company Act”

2. Section 7.01 of the Credit Agreement is hereby amended by (i) deleting the unnumbered final paragraph thereof, (ii) deleting the word “and” at the end of paragraph (e) thereof, (iii) replacing the period at the end of paragraph (f) thereof with “; and”, and (iv) inserting the following new paragraph (g).

(g) Liens arising in connection with customary fees and expenses and for advances and other payments due to the Borrower’s custodian in the ordinary course of business.

3. The Credit Agreement is hereby amended by adding the following new Section 10.21:

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