RE:  Fourteenth Amendment to Credit Suisse Family of Funds Line of Credit

Ladies and Gentlemen:

State Street Bank and Trust Company (the “Bank”) has made available to each of the investment companies registered under the Investment Company Act listed on Appendix I attached to the Loan Agreement referred to below (each, a “Borrower”), each acting on behalf of its respective Funds as specified from time to time on such Appendix I thereto (each such fund series, a “Fund”), a $250,000,000.00 committed, unsecured line of credit (the “Committed Line”) as described in a letter agreement dated June 10, 2009, by and among the Borrowers and the Bank (as amended, the “Loan Agreement”).  The obligations of the Borrowers arising under the Committed Line are evidenced by an amended and restated promissory note in the original principal amount of $250,000,000.00 dated March 11, 2016 (as amended, the “Note”).  Any capitalized term not otherwise defined herein shall have the same meanings as set forth in the Loan Agreement.

The Borrowers have requested, and the Bank has agreed, to extend the Committed Line for an additional 364-day period from the date hereof and to further amend the Loan Documents as set forth below.  Therefore, for good and valuable consideration, the receipt of which is hereby acknowledged, the Borrowers, on behalf of their respective Funds, and the Bank agree as follows:

I. Amendments to Loan Documents

1. Section I(1) of the Loan Agreement is hereby amended by deleting the first sentence in its entirety and substituting the following therefor:  “The Committed Line shall expire on March 8, 2019 (the “Expiration Date”), unless extended by mutual agreement of the Bank and the Borrowers or, with respect to any Fund, terminated by a Borrower on behalf of such Fund as provided herein.”

2. The Borrowers had previously informed the Bank that Credit Suisse Emerging Markets Equity Fund, a series of Credit Suisse Opportunity Funds, was

terminated as a “Fund” under the Loan Documents effective September 1, 2017, and was accordingly terminated as a “Fund” for all purposes under the Loan Documents.

3. The Appendix I to each of the Loan Agreement and Note is hereby deleted in its entirety and the Appendix I attached hereto is substituted in each instance thereof.

II. Upfront Fee

As a condition precedent to the effectiveness of this letter agreement, the Borrowers shall pay to the Bank on the date of this letter agreement a non-refundable fee equal to 0.05% of the Committed Line Amount, which fee shall be fully earned by the Bank upon the date of this letter agreement.

III. Miscellaneous

1. Other than as amended hereby, all terms and conditions of the Loan Agreement and all related Loan Documents are ratified and affirmed as of the date hereof and extended in order to give effect to the terms hereof.

2. Each of the Borrowers, for itself and on behalf of each of its respective Funds, represents and warrants to the Bank as follows:  (a) no Default or Event of Default has occurred and is continuing on the date hereof under the Loan Documents; (b) each of the representations and warranties of such Borrower contained in the Loan Agreement is true and correct in all material respects on and as of the date of this letter amendment; (c) the execution, delivery and performance of this letter amendment, the Note and the Loan Documents, as amended hereby (collectively, the “Amended Loan Documents”):  (i) are, and will be, within such Borrower’s or Fund’s power and authority, (ii) have been authorized by all necessary proceedings, (iii) do not, and will not, require any consents or approvals including from any governmental authority other than those which have been received, (iv) will not contravene any provision of, or exceed any limitation contained in, the declaration of trust certificate or articles of incorporation or by-laws or other organizational documents of such Borrower or such Fund or any law, rule or regulation applicable to such Borrower or such Fund, (v) do not constitute a default under any other agreement, order or undertaking binding on such Borrower or such Fund, and (vi) do not require the consent or approval of any other party other than for those consents and approvals which have been received; and (d) each of the Amended Loan Documents constitutes the legal, valid, binding and enforceable obligation of such Borrower and such Fund, except as the same may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting the enforcement of creditors’ rights generally and by general equitable principles.

3. Upon receipt of a fully executed copy of this letter amendment and such other documents or instruments as the Bank may reasonably request, this letter amendment

shall constitute an amendment to the Loan Documents to be governed by the laws of the Commonwealth of Massachusetts.
