Dear Sir/Madam:

The Asia Bond Fund of Credit Suisse Institutional Fund, Inc. (the “Fund”), a corporation organized and existing under the laws of the State of Maryland, and Credit Suisse Asset Management, LLC, as investment adviser to the Fund (“Credit Suisse”), herewith confirm their agreement with Credit Suisse Asset Management (Australia) Limited (the “Sub-Adviser”), a company registered under the laws of the State of Victoria, Australia, as follows:

1.             Investment Description; Appointment

The Fund desires to employ the capital of the Fund by investing and reinvesting in securities of the kind and in accordance with the limitations specified in the Fund’s Articles of Incorporation, as may be amended from time to time (the “Articles of Incorporation”), and in the Fund’s Prospectus(es) and Statement(s) of Additional Information, as from time to time in effect (the “Prospectus” and “SAI,” respectively), and in such manner and to such extent as may from time to time be approved by the Board of Directors of the Fund. Copies of the Prospectus, SAI and Articles of Incorporation have been or will be submitted to the Sub-Adviser. The Fund agrees to promptly provide the Sub-Adviser copies of all amendments to the Prospectus and SAI on an on-going basis. The Fund employs Credit Suisse as its investment adviser. Credit Suisse desires to employ and hereby appoints the Sub-Adviser to act as its sub-investment adviser upon the terms set forth in this Agreement. The Sub-Adviser accepts the appointment and agrees to furnish the services set forth below for compensation.

2.             Services as Sub-Investment Adviser

(a)           Subject to the supervision and direction of Credit Suisse, the Sub-Adviser will provide investment advisory and portfolio management advice to all or that portion of the Fund’s assets designated by Credit Suisse from time to time (the “Assets”) in accordance with (a) the Articles of Incorporation, (b) the Investment Company Act of 1940, as amended (the “1940 Act”), and the Investment Advisers Act of 1940, as amended (the “Advisers Act”), and all applicable Rules and Regulations of the Securities and Exchange Commission (the “SEC”) and all other applicable laws and

regulations, and (c) the Fund’s investment objective and policies as stated in the Prospectus and SAI and investment parameters provided by Credit Suisse from time to time. In connection therewith, the Sub-Adviser will:

(i)            manage the Assets or furnish recommendations to manage the Assets in accordance with the Fund’s investment objective and policies;

(ii)           make investment decisions or recommendations with respect to the Assets;

(iii)          if requested by Credit Suisse will place purchase and sale orders for securities on behalf of the Fund with respect to the Assets;

(iv)          exercise voting rights with respect to the Assets if requested by Credit Suisse; and

(v)           furnish Credit Suisse and the Fund’s Board of Directors with such periodic and special reports as the Fund or Credit Suisse may reasonably request.

In providing those services, the Sub-Adviser will, if requested by Credit Suisse, provide investment research and supervision of the Assets and conduct a continued program of investment, evaluation and, if appropriate, sale and reinvestment of the Assets.

(b)           In connection with the performance of the services of the Sub-Adviser provided for herein, the Sub-Adviser may contract at its own expense with third parties for the acquisition of research, clerical services and other administrative services that would not require such parties to be required to register as an investment adviser under the Advisers Act; provided that the Sub-Adviser shall remain liable for the performance of its duties hereunder.

3.             Execution of Transactions

(a)           In executing transactions for the Assets, selecting brokers or dealers and negotiating any brokerage commission rates, the Sub-Adviser will use its best efforts to seek best execution. In assessing best execution available for any portfolio transaction, the Sub-Adviser will consider all factors it deems relevant including, but not limited to, the breadth of the market in the security, the price of the security, the financial condition and execution capability of the broker or dealer and the reasonableness of any commission for the specific transaction and for transactions executed through the broker or dealer in the aggregate. In selecting brokers or dealers to execute a particular transaction and in evaluating the best overall terms available, to the extent that the execution and price offered by more than one broker or dealer are comparable the Sub-Adviser may consider any brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934) provided to the Sub-Adviser or to Credit Suisse for use on behalf of the Fund or other clients of the Sub-Adviser or Credit Suisse.

2

(b)           It is understood that the services of the Sub-Adviser are not exclusive, and nothing in this Agreement shall prevent the Sub-Adviser from providing similar services to other investment companies or from engaging in other activities, provided that those activities do not adversely affect the ability of the Sub-Adviser to perform its services under this Agreement. The Fund and Credit Suisse further understand and acknowledge that the persons employed by the Sub-Adviser to assist in the performance of its duties under this Agreement will not devote their full time to that service. Nothing contained in this Agreement will be deemed to limit or restrict the right of the Sub-Adviser or any affiliate of the Sub-Adviser to engage in and devote time and attention to other businesses or to render services of whatever kind or nature, provided that doing so does not adversely affect the ability of the Sub-Adviser to perform its services under this Agreement.

(c)           On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund as well as of other investment advisory clients of the Sub-Adviser, the Sub-Adviser may, to the extent permitted by applicable laws and regulations, but shall not be obligated to, aggregate the securities to be so sold or purchased with those of its other clients. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in a manner that is fair and equitable, in the judgment of the Sub-Adviser, in the exercise of its fiduciary obligations to the Fund and to such other clients. The Fund recognizes that the effect of the aggregation may operate on some occasions to the Fund’s advantage or disadvantage. The Sub-Adviser shall provide to Credit Suisse and the Fund all information reasonably requested by Credit Suisse and the Fund relating to the decisions made by the Sub-Adviser regarding allocation of securities purchased or sold, as well as the expenses incurred in a transaction, among the Fund and the Sub-Adviser’s other investment advisory clients.

(d)           In connection with the purchase and sale of securities for the Fund, the Sub-Adviser will provide such information as may be reasonably necessary to enable the custodian and co-administrators to perform their administrative and recordkeeping responsibilities with respect to the Fund.
