Exhibit (d)(8)

AGREEMENT made this 15th day of September, 2011, between Deutsche Investment Management Americas Inc. (the “Adviser”) and Deutsche Alternative Asset Management (Global) Limited (the “Sub-Adviser”).

WHEREAS, DWS Climate Change Fund (the “Fund”), is a series of DWS Securities Trust, a Massachusetts Business Trust (the “Trust”), which is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”); and

WHEREAS, the Adviser has entered into an Investment Management Agreement dated June 1, 2006 with the Trust and made effective with respect to the Fund on September 6, 2007 (such agreement and any successor agreement thereto, the “Advisory Agreement”), pursuant to which the Adviser acts as investment manager to the Fund and provides certain investment advisory and other services with respect to the Fund; and

WHEREAS, the Adviser, with the approval of the Trust’s Board of Trustees, including a majority of the Trustees who are not “interested persons,” as defined in the 1940 Act, desires to retain the Sub-Adviser to provide investment advisory services in connection with the management of the Fund, and the Sub-Adviser is willing to render such investment advisory services.

NOW, THEREFORE, the parties hereto agree as follows:

Duties of the Sub-Adviser. Subject to supervision and oversight by the Adviser and the Fund’s Board of Trustees, the Sub-Adviser shall manage all of the securities and other assets of the Fund entrusted to it by the Adviser hereunder (the “Assets”), including the purchase, retention and disposition of the Assets, in accordance with the Fund’s investment objective, policies and restrictions as stated in the Fund’s prospectus, statement of additional information, as currently in effect and as amended or supplemented from time to time (referred to collectively as the “Prospectus”), and subject to the following:

(a)

In the performance of its duties and obligations under this Agreement, the Sub-Adviser shall act in conformity with the Trust’s constituent documents and the Prospectus (the “Operating Documents” and attached hereto as Appendix B) which have been put into effect in conformity by and with the instructions and directions of the Adviser and of the Board of Trustees of the Trust and will conform to and comply with the requirements of the 1940 Act, the Internal Revenue Code of 1986, as amended (the “Code”), and all other applicable federal and state laws and regulations, as each is amended from time to time; provided however, that the Sub-Adviser shall be under no obligation to comply with any amendment and/or supplement to the Prospectus until such time as the Sub-Adviser has been notified of and has agreed to any and all such amendment and/or supplement and to the extent that such amendment and/or supplement relates to

the services provided by the Sub-Adviser under this Agreement. The Adviser shall inform the Sub-Adviser of any changes to the 1940 Act or other applicable federal and state laws having effect on the services provided by the Sub-Adviser under this Agreement.

(b)

The Sub-Adviser shall determine the Assets to be purchased or sold by the Fund and will place orders with or through only those brokers or dealers that appear on a list of brokers and dealers approved by the Adviser and made available to the Sub-Adviser from time to time. The Sub-Adviser will carry out the policy with respect to brokerage set forth in the Fund’s registration statement and the Prospectus or as the Board of Trustees or the Adviser may direct from time to time, in conformity with federal securities laws. In executing portfolio transactions and selecting brokers or dealers, the Sub-Adviser will use its best efforts to obtain on behalf of the Fund best execution. In evaluating best execution for any transaction, the Sub-Adviser shall consider all factors that it deems relevant, including 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 the commission, if any, both for the specific transaction and on a continuing basis. In evaluating best execution, and in selecting the broker-dealer to execute a particular transaction, subject to any instructions and directions of the Adviser or the Board of Trustees, the Sub-Adviser may also consider the brokerage and research services provided (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934). Provided the Sub-Adviser is acting in accordance with any such instructions and directions of the Adviser or the Board of Trustees, the Sub-Adviser is authorized to pay to a broker or dealer who provides such brokerage and research services a commission for executing a portfolio transaction for the Fund which is in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if, but only if, the Sub-Adviser determines in good faith that such commission was reasonable in relation to the value of the brokerage and research services provided by such broker or dealer -- viewed in terms of that particular transaction or in terms of the overall responsibilities of the Sub-Adviser to the Fund. In no instance, however, will the Fund’s Assets be purchased from or sold to the Adviser, the Sub-Adviser, any other sub-adviser of the Fund or other registered investment companies (or series or portions thereof) that may be deemed to be under common control, the Fund’s principal underwriter, or any affiliated person of either the Fund, the Adviser, the Sub-Adviser or any other sub-adviser of the Fund or other registered investment companies (or series or portions thereof) that may be deemed to be under common control, or the Fund’s principal underwriter, acting as principal in the transaction, except to the extent permitted by the Securities and Exchange Commission (“SEC”) and the 1940 Act and approved by (or pursuant to procedures of) the Adviser and the Board of Trustees. The Adviser or its affiliates may, from time to time, engage other sub-advisers to advise the Fund (or portions thereof), other series of the Trust (or portions thereof) or other registered investment companies (or series or portions thereof) that may be deemed to be under common control (each a “Sub-Advised Fund”). The Sub-Adviser agrees that it will not consult with any other sub-adviser engaged by the Adviser or its affiliates with respect to transactions in

adviser engaged by the Adviser or its affiliates with respect to transactions in securities or other assets concerning the Fund or another Sub-Advised Fund, except to the extent permitted by the certain exemptive rules under the 1940 Act that permit certain transactions with a sub-adviser or its affiliates.

On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interests of the Fund as well as other clients of the Sub-Adviser, the Sub-Adviser, to the extent permitted by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities to be sold or purchased in order to obtain the most favorable price or lower brokerage commissions and efficient execution. In such event, allocation of securities so sold or purchased, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in the manner the Sub-Adviser considers to be the most equitable and consistent with its fiduciary obligations to the Fund and to such other clients.

The Sub-Adviser may, but shall be under no obligation to, buy securities for the Fund at the same time it is selling such securities for another client account and may sell securities for the Fund at the time it is buying such securities for another client account. In such cases, subject to applicable legal and regulatory requirements, and in compliance with such procedures of the Fund as may be in effect from time to time, the Sub-Adviser may effectuate cross transactions between the Fund and such other account if it deems this to be advantageous to both of the accounts involved.

Notwithstanding the foregoing, the Sub-Adviser agrees that the Adviser shall have the right by written notice to identify securities that may not be purchased on behalf of the Fund.

(c)

The Sub-Adviser shall keep the Adviser informed of developments materially affecting the Fund. The Sub-Adviser shall provide to the Adviser or the Board of Trustees such information as provided for in Appendix A to this Agreement.

The Sub-Adviser shall keep and maintain the books and records relating to the Assets required to be kept and maintained by the Sub-Adviser under this Agreement. The Adviser shall inform the Sub-Adviser in a timely manner about such information relating to the Sub-Adviser’s services under this Agreement needed by the Adviser or the Fund under law applicable to the Adviser or the Fund. The Sub-Adviser shall also furnish to the Adviser, upon written request by the Adviser, any other reasonable information relating to the Assets that is required to be filed by the Adviser or the Fund with the SEC or sent to shareholders under the 1933 Act or 1940 Act (including the rules adopted thereunder) or any exemptive or other relief that the Adviser or the Fund obtains from the SEC. The Sub-Adviser agrees that it will provide copies of such records it maintains pursuant to this Agreement upon the Fund’s request; provided, however, that the Sub-Adviser may also retain a copy of such records. The Sub-Adviser agrees to permit the Adviser, the Fund’s officers and the Fund’s independent registered public accounting firm to inspect and audit such records pertaining to the Fund at reasonable times during regular business hours upon due written notice. In addition, for the duration of this Agreement, the Sub-Adviser shall preserve for the periods prescribed by Rule 31a-2 under the 1940 Act, and

Rule 204-2 under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), any such records as are required to be maintained by it pursuant to this Agreement, and shall transfer said records to any successor sub-adviser and to the Adviser upon the termination of this Agreement at the Fund’s request provided, however, that the Sub-Adviser may also retain a copy of such records. The Sub-Adviser shall maintain and enforce adequate security procedures with respect to all materials, records, documents and data relating to any of its responsibilities under this Agreement including all means for the effecting of securities transactions.

(d)

The Sub-Adviser will make its officers and employees available to meet with the officers of the Adviser and the Trust’s officers and Trustees on due notice to review the investments and investment program of the Fund in the light of current and prospective economic and market conditions. In addition, the Sub-Adviser shall, as reasonably requested by the Adviser, for itself and on behalf of the Fund, furnish to the Adviser from time to time whatever information the Adviser reasonably believes appropriate for this purpose. From time to time as the Adviser for itself and on behalf of the Fund may reasonably request, the Sub-Adviser will furnish to the Adviser, at the Sub-Adviser’s expense, reports on portfolio transactions and reports on issuers of securities held by the Fund, all in such detail as the Fund or the Adviser may reasonably request. In addition, the Sub-Adviser shall provide advice and assistance to the Adviser as to the determination of the value of securities held or to be acquired by the Fund for valuation purposes in accordance with the process described in the Fund’s Prospectus and valuation procedures. The Sub-Adviser will make its officers and employees available to meet with the officers of the Adviser and the Trust’s officers and Trustees and provide such information as the Board of Trustees and the Adviser reasonably believe appropriate for purposes of the Board’s consideration of this Agreement and any continuations thereof, including information about the profitability to the Sub-Adviser of providing advisory services hereunder.

(e)

The Sub-Adviser shall provide the Fund’s custodian and the Fund’s Accountant with each business day’s information relating to all matched transactions concerning the Fund’s Assets, including the name of the issuer, the description and amount or number of shares of the security purchased or sold, the market price, commission and gross or net price, trade date, settlement date and identity of the effecting broker or dealer, and such other information as may be reasonably required. The Sub-Adviser shall additionally provide the Fund’s Accountant with a trade log with the above information of all matched and unmatched transactions. The Sub-Adviser shall also provide the Adviser with such information upon written request of the Adviser. The Adviser is required to notify and inform the compliance department of the Sub-Adviser in advance of any reports and documents which are necessary to comply with the legal requirements of the Fund. The Sub-Adviser shall provide such sub-certifications as officers of the Adviser or the Trust may reasonably request in connection with the filings of Form N-CSR or Form N-Q (or any similar form) by the Fund.

The parties to this Agreement agree that the Fund has made arrangements for the safekeeping of any of the Fund’s assets (and the Fund’s documents of title) with such custodian as chosen by the Adviser from time to time with notice to the Sub-Adviser of the same. The Sub-Adviser shall not hold any asset of the Fund (or the Fund’s documents of title, if any) on behalf of the Fund or the Adviser.

(f)

In the performance of its duties hereunder, the Sub-Adviser is and shall be an independent contractor and, except as expressly provided for herein or otherwise expressly provided or authorized in writing by the Adviser, shall have no authority to act for or represent the Fund or the Trust in any way or otherwise be deemed to be an agent of the Fund, the Trust or the Adviser. If any occasion should arise in which the Sub-Adviser gives any advice to its clients concerning the shares of the Fund, the Sub-Adviser will act solely as investment counsel for such clients and not in any way on behalf of the Fund. The Sub-Adviser’s services to the Fund pursuant to this Agreement are not to be deemed to be exclusive, and it is understood that the Sub-Adviser may render investment advice, management and other services to other investment companies and clients. The Sub-Adviser may provide advice and take certain actions with respect to clients other than the Fund or for the Sub-Adviser’s own accounts that may differ from the advice or the timing or nature of actions taken with respect to the Fund. Furthermore, the Sub-Adviser shall have no obligation to recommend the purchase or sale of any asset on behalf of the Fund that the Sub-Adviser or an affiliate may purchase or sell for its own account or for the account of any clients of the Sub-Adviser.

(g)

Subject to the following, the Sub-Adviser shall take corporate action elections with respect to securities held by the Fund in accordance with such guidelines established by the Adviser and approved by the Board of Trustees that the Adviser has provided to the Sub-Adviser in writing.

For the avoidance of doubt, the Sub-Adviser shall not be responsible for exercising any voting rights relating to any of the Assets of the Fund. The Sub-Adviser shall not provide any advice or act on behalf of the Fund or the Adviser in any class action proceedings involving assets held by the Fund or Assets of issuers of securities held by the Fund.

Duties of the Adviser. The Adviser shall continue to have responsibility for all services to be provided to the Fund pursuant to the Advisory Agreement and shall supervise and oversee the Sub-Adviser’s performance of its duties under this Agreement; provided, however, that in connection with its management of the Assets, nothing herein shall be construed to relieve the Sub-Adviser of responsibility for compliance with the Operating Documents, the instruction and directions of the Board of Trustees of the Trust, the requirements of the 1940 Act, the Code, and all other applicable federal and state laws and regulations, as each is amended from time to time.
