THIS AMENDMENT, dated as of October 12, 2006 between DWS RREEF Global Real Estate Securities Fund (the “Fund”), a registered investment company duly registered with the Securities and Exchange Commission under the 1940 Act, and XXXXX BROTHERS XXXXXXXX & CO., a limited partnership formed under the laws of the State of New York (“BBH&Co.” or the “Custodian”), amends the Custodian Agreement between the parties dated October 12, 2006 (the “Custodian Agreement”).

W I T N E S S E T H:

WHEREAS, the Fund has employed BBH&Co. to act as custodian for the Fund and to provide related services, all as provided in the Custodian Agreement;

WHEREAS, the Securities and Exchange Commission has promulgated Rules 17f-5 and 17f-7 under the Investment Company Act of 1940 which establish rules regarding the Fund’s investments held outside the United States by subcustodians or through Securities Depositories; and

WHEREAS, BBH&Co. is willing to provide services in connection with such Rules in accordance with the terms of this Amendment to the Custodian Agreement;

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, the Fund and BBH&Co. hereby agree, as follows:

1.	That Article II - Powers and Duties of Custodian shall be amended by the inclusion of the following subsection:

2.26 Deposit of Fund Assets in Foreign Securities Depositories. Unless instructed otherwise by the Fund, the Custodian may deposit and/or maintain non-U.S. investments of the Fund in any non-U.S. Securities Depository provided such Securities Depository either meets the requirements of an "eligible securities depository" under Rule 17f-7 promulgated under the 1940 Act, or any successor rule or regulation ("Rule 17f-7") or by order of the Securities and Exchange Commission is exempted therefrom. Prior to the time that securities are placed with such depository the Custodian shall have prepared an analysis of the custody risks associated with maintaining assets with the Securities Depository and shall have established a system to monitor such risks on a continuing basis in accordance with Sub-section 2.26.1 of this Section. An instruction to open an account in a given country shall comprise authorization for the Custodian to hold assets in such country in accordance with the terms of this Agreement. The Custodian shall not be required to make independent inquiry as to the authorization of the Fund to invest in such country.

2.26.1 Monitoring and Risk Assessment of Securities Depositories. Prior to the placement of any assets of the Fund with a Securities Depository, the Custodian: (a) shall provide to the Fund, its investment adviser or its authorized representative an assessment of the custody risks associated with maintaining assets within such Securities Depository in accordance with Rule 17f-7(a)(1)(i)(A), and (b) shall have established a system to monitor the custody risks associated with maintaining assets with such Securities Depository on a continuing basis and to promptly notify the Fund or its investment adviser of any material changes in such risk in accordance with Rule 17f-7(a)(1) (i)(B). In performing its duties under this subsection, the Custodian shall use reasonable care, prudence and diligence and may rely on such reasonable sources of information as may be available including but not limited to: (i) published ratings; (ii) information supplied by a Subcustodian that is a participant in such Securities Depository; (iii) industry surveys or publications; (iv) information supplied by the depository itself, by its auditors (internal or external) or by the relevant Foreign Financial Regulatory Authority. It is acknowledged that information procured through some or all of these sources may not be independently verifiable by the Custodian and that direct access to Securities Depositories is limited under most circumstances. Accordingly, the Custodian shall not be responsible for errors or omissions in its duties hereunder provided that it has performed its monitoring and assessment duties in accordance with the standard of care set forth above in this sub-section 2.26.1. The risk assessment shall be

provided to the Fund or its Investment Adviser or its authorized representative by such means as the Custodian shall reasonably establish. The form and substance of the risk assessment shall be agreed upon by the parties. Advice of material change in such assessment may be provided by the Custodian in the manner established as customary between the Fund and the Custodian for transmission of material market information.

2. That Article IV - Subcustodians shall be amended by the inclusion of the following at the end of Sub-section 4.2.(a) Foreign Subcustodians and Interim Subcustodians.:

(a)(1) Delegation of Directors/Trustees Review of Subcustodians. From time to time, the Custodian may agree to perform certain reviews of Subcustodians and of Subcustodian Contracts as delegate of the Fund's Directors/Trustees. In such event, the Custodian's duties and obligations with respect to this delegated review will be performed in accordance with the terms of the attached 17f-5 Delegation Schedule to this Agreement.

3. In addition, that the definitions under the Custodian Agreement shall be amended with the addition modification of the following:

Foreign Financial Regulatory Authority shall have the meaning given by Section 2(a)(50) of the 1940 Act.

Securities Depository shall mean a central or book entry system or agency established under Applicable Law for purposes of recording the ownership and/or entitlement to investment securities for a given market that, if a foreign Securities Depository, meets the definitional requirements of Rule 17f-7 under the 1940 Act.

All defined terms used herein shall have the meaning given to such terms in the Custodian Agreement as amended by this Amendment.

IN WITNESS WHEREOF, each of the parties hereto has caused this Amendment to be duly executed as of the date first above written.

(iii) That beneficial ownership of the Fund's Foreign Assets will be freely transferable without the payment of money or value other than for safe custody or administration;
