WHEREAS, the Sub-Adviser is also registered with the Commission as an investment adviser under the Advisers Act;

WHEREAS, the Adviser and the Trust have entered into an investment advisory agreement (the “Investment Advisory Agreement”), pursuant to which the Adviser manages the investment operations of each Fund and may delegate certain duties of the Adviser to one or more investment sub-adviser(s);

WHEREAS, the Adviser, with the approval of the Board of Trustees of the Trust (the “Board”), including a majority of the Trustees who are not “interested persons” (defined herein) of any party to this Agreement, desires to delegate to the Sub-Adviser the duty to manage the portfolio investments of the Funds; and

WHEREAS, this Agreement supersedes a prior investment sub-advisory agreement among the parties, dated September 30, 2006, that has been terminated as a result of its assignment in connection with a change of control of the Sub-Adviser;

NOW, THEREFORE, in consideration of the promises and mutual covenants herein contained, it is agreed among the parties hereto as follows:

1. Appointment of Sub-Adviser. The Adviser hereby appoints the Sub-Adviser and the Sub-Adviser hereby agrees to manage the portfolio investments of each Fund subject to the terms of this Agreement and subject to the supervision of the Adviser and the Board.

2. Services of Sub-Adviser. The Sub-Adviser shall perform all services necessary for the management of the portfolio investments of each Fund, including but not limited to:

(a)

Managing the investment and reinvestment of all assets, now or hereafter acquired by each Fund, including determining what securities and other investments are to be purchased or sold for each Fund and executing transactions accordingly;

(b)

Transmitting trades to each Fund’s custodian for settlement in accordance with each Fund’s procedures and as may be directed by the Trust;

(c)

Assisting in the preparation of all shareholder communications, including shareholder reports, and participating in shareholder relations;

(d)

Making recommendations, or making determinations under authority delegated by the Adviser or the Trust, as to the manner in which voting rights, rights to consent to Fund action and any other rights pertaining to each Fund’s portfolio securities shall be exercised; provided, however, that the Sub-Adviser shall be given reasonable prior notice should the Adviser or the Trust determine to direct the Sub-Adviser in its exercise of such rights;

(e)

Making recommendations to the Adviser and the Board with respect to Fund investment policies and procedures, and carrying out such investment policies and procedures as are approved by the Board or by the Adviser under authority delegated by the Board to the Adviser;

(f)

Supplying reports, evaluations, analyses, statistical data and information within its possession or control to the Adviser, the Board or to the Funds’ officers and other service providers as the Adviser or the Board may reasonably request from time to time or as may be necessary or appropriate for the operation of the Trust as an open-end investment company or as necessary to comply with Section 3(a) of this Agreement;

(g)

Maintaining all required books and records with respect to the investment decisions and securities transactions for each Fund;

(h)

Furnishing any and all other services, subject to review by the Board, that the Adviser from time to time reasonably determines to be necessary to perform its obligations under the Investment Advisory Agreement or as the Board may reasonably request from time-to-time.

3. Responsibilities of Sub-Adviser. In carrying out its obligations under this Agreement, the Sub-Adviser agrees that it will:

(a)

Comply with all applicable law, including but not limited to the 1940 Act and the Advisers Act, the rules and regulations of the Commission thereunder and the conditions of any order affecting the Trust or a Fund issued thereunder;

(b)

Use the same skill and care in providing such services as it uses in providing services to other fiduciary accounts for which it has investment responsibilities;

(c)

The Sub-Adviser acknowledges that the Funds may engage in transactions with certain investment sub-advisers in the Columbia Funds Family (and their affiliated persons) in reliance on exemptions under Rule 10f-3, Rule 12d3-1, Rule 17a-10 and Rule 17e-1 under the 1940 Act. Accordingly, the Sub-Adviser hereby agrees that it will not consult with any other investment sub-adviser of a Columbia Fund in the Columbia Funds Family concerning transactions for a Fund in securities or other investments, other than for purposes of complying with the conditions of Rule 12d3-1(a) and (b). With respect to a Fund with one or more investment sub-advisers in addition to the Sub-Adviser, the Sub-Adviser shall be limited to providing investment advice only with respect to the portion of the Fund’s assets as the Adviser may determine from time to time, and shall not consult with any other investment sub-adviser to the Fund that is a principal underwriter or an affiliated person of a principal underwriter concerning transactions for the Fund in securities or other investments.

(d)

Not make loans to any person for the purpose of purchasing or carrying Fund interests;

(e)

Place, or arrange for the placement of, all orders pursuant to its investment determinations for the Funds either directly with the issuer or with any broker or dealer (including any affiliated broker or dealer). In executing portfolio transactions and selecting brokers or dealers, the Sub-Adviser will use its best efforts to seek on behalf of each Fund the best overall terms available. In assessing the best overall terms available 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 the best overall terms available, and in selecting the broker or dealer to execute a particular transaction, the Sub-Adviser may also consider whether such broker or dealer furnishes research and other information or services to the Sub-Adviser; and

(f)

Adhere to the investment objective, strategies, policies and procedures of the Trust adopted on behalf of each Fund.

4. Confidentiality of Information. Each party agrees that it will treat confidentially all information provided by another party regarding such other party’s business and operations, including without limitation the investment activities or holdings of a Fund. All confidential information provided by a party hereto shall not be disclosed to any unaffiliated third party without the prior consent of the providing party. The foregoing shall not apply to any

information that is public when provided or thereafter becomes public or which is required to be disclosed by any regulatory authority in the lawful and appropriate exercise of its jurisdiction over a party, by any auditor of the parties hereto, by judicial or administrative process or otherwise by applicable law or regulation.

5. Services Not Exclusive. The services furnished by the Sub-Adviser hereunder are deemed not to be exclusive, and the Sub-Adviser shall be free to furnish similar services to others so long as its provision of services under this Agreement is not impaired thereby. To the extent that the purchase or sale of securities or other investments of the same issuer may be deemed by the Sub-Adviser to be suitable for two or more accounts managed by the Sub-Adviser, the available securities or investments may be allocated in a manner believed by the Sub-Adviser to be equitable to each account. It is recognized that in some cases this procedure may adversely affect the price paid or received by a Fund or the size of the position obtainable for or disposed of by a Fund.

any and all applicable policies and procedures approved by the Board.

The Trust will promptly furnish the Sub-Adviser with copies of any and all amendments of or additions or supplements to the foregoing.

For the purposes of this paragraph, the definitions contained in Section 2(a) of the 1940 Act and the applicable rules under the 1940 Act shall apply.
