AMENDED AND RESTATED

RULE 18f-3 MULTI-CLASS PLAN

COLUMBIA FUNDS SERIES TRUST

I. Introduction.

Pursuant to Rule 18f-3 under the Investment Company Act of 1940, as amended (the “1940 Act”), this Rule 18f-3 Multi-Class Plan (“Plan”) sets forth the methods for allocating fees and expenses among the classes of shares (“Shares”) in the investment portfolios (the “Funds”) of the Columbia Funds Series Trust (the “Trust”) listed in Schedule A. Among other things, this Plan identifies expenses that may be allocated to a particular class of Shares to the extent that they are actually incurred in a different amount by the class or relate to a different kind or degree of services provided to the class. In addition, this Plan sets forth the maximum initial sales charges (or “loads”), contingent deferred sales charges, maximum distribution fees, maximum shareholder servicing fees, maximum shareholder administration fees, conversion features, exchange privileges, other shareholder policies and services and transfer agency fees, if any, applicable or allocated to each class of Shares of the Trust.

The Trust is an open-end series investment company registered under the 1940 Act, the Shares of which are registered on Form N-1A under the Securities Act of 1933. The Trust offers multiple classes of Shares in its Funds pursuant to the provisions of Rule 18f-3 and this Plan.

Each Fund and the classes of Shares representing interests in the Fund it issues are set forth in Schedule A hereto. Schedule A shall be updated by officers of the Trust from time to time as necessary to reflect the current classes and Funds offered by the Trust.

II. Allocation of Expenses.

1. Except as otherwise set forth herein or as may from time to time be specifically approved by the board of trustees of the Trust (the Trustees), all expenses of each Fund shall be allocated proportionately among the classes of such Fund pro rata based on the relative net assets of each class. Pursuant to Rule 18f-3, the Trust shall allocate to each class of Shares in a Fund any fees and expenses incurred by the Trust in connection with the distribution and/or the provision of shareholder services to holders of such class of Shares under any distribution plan, shareholder servicing plan and/or plan administration agreement (a “Distribution/Shareholder Servicing Plan”).

2. In addition, pursuant to Rule 18f-3, the Trust may allocate to a particular class of Shares the following fees and expenses, if any, but only to the extent they relate to (as defined below) the particular class of Shares:

(i) transfer agency fees and expenses identified by the Registrant’s transfer agent or officers as being fees and expenses that relate to such class of Shares (see paragraph 7 below);

(ii) printing and postage expenses of preparing and distributing materials such as shareholder reports, prospectuses, reports and proxies to current shareholders of such class of Shares or to regulatory agencies that relate to such class of Shares;

(iii) blue sky registration or qualification fees that relate to such class of Shares;

(iv) Securities and Exchange Commission registration fees that relate to such class of Shares;

(v) expenses of administrative personnel and services (including, but not limited to, those of a portfolio accountant, custodian or dividend paying agent charged with calculating net asset values and determining or paying distributions) as required to support the shareholders of such class of Shares;

(vi) litigation or other legal expenses that relate to such class of Shares;

(vii) fees of the Trustees of the Trust incurred as a result of issues that relate to such class of Shares;

(viii) independent accountants’ fees that relate to such class of Shares; and

(ix) any other fees and expenses that relate to such class of Shares.

Notwithstanding the foregoing, the Trust may not allocate advisory or custodial fees or other expenses related to the management of a Fund’s assets to a particular class, except that the Trust may cause a class to pay a different advisory fee to the extent that any difference in amount paid is the result of the application of the same performance fee provisions, if any, in the advisory contract of the Fund to the different investment performance of each class.

3. For all purposes under this Plan, fees and expenses “that relate to” a class of Shares are those fees and expenses that are actually incurred in a different amount by the class or that relate to a different kind or degree of services provided to the class. The officers of the Trust shall have the authority to determine, to the extent permitted by applicable law or regulation and/or U.S. Securities and Exchange Commission guidance, whether any or all of the fees and expenses described in paragraph 2 above should be allocated to a particular class of Shares. The Treasurer, any Deputy or Assistant Treasurer or another appropriate officer of the Trust shall periodically or as frequently as requested by the independent Trustees report to the Board of Trustees regarding any such allocations.

4. For all purposes under this Plan, “Daily Dividend Fund” means any Fund that has a policy of declaring distributions of net investment income daily, including any money market fund that determines net asset value using the amortized cost method permitted by Rule 2a-7 under the 1940 Act.

5. Income and any expenses of Daily Dividend Funds that are not allocated to a particular class of any such Fund pursuant to this Plan shall be allocated to each class of the Fund on the basis of the net assets of that class in relation to the net assets of the Fund, excluding the value of subscriptions receivable (the “Settled Shares Method”).

Realized and unrealized capital gains and losses of Daily Dividend Funds that are not allocated to a particular class of any such Fund pursuant to this Plan shall be allocated to each class of the Fund on the basis of the net assets of that class in relation to the net assets of the Fund (the “Relative Net Assets Method”).

6. Income, realized and unrealized capital gains and losses, and any expenses of Funds that are not Daily Dividend Funds that are not allocated to a particular class of any such Fund pursuant to this Plan shall be allocated to each class of the Fund on the basis of the Relative Net Assets Method.

7. Transfer agency costs vary among classes, and are calculated separately for each of (a) Institutional 3 Class Shares (formerly Class Y Shares), (b) Institutional 2 Class Shares (formerly Class R5 Shares), and (c) all other classes of Shares. Shares of each Class pay an annual fee set forth in the transfer agency agreement in effect from time to time and an allocable share of reimbursable out-of-pocket expenses, with the allocation among the classes based on the number of open accounts. Shares of each Class (other than Institutional 3 Class Shares) pay sub-transfer agency fees as set forth in the transfer agency agreement in effect from time to time.

8. In certain cases, a Fund service provider may waive or reimburse all or a portion of the expenses of a specific class of Shares of the Fund. The applicable service provider shall report to the Board of Trustees regarding any such waivers or reimbursements, including why they are consistent with the fair and equitable treatment of shareholders of all classes.
