Dear Sirs:

This will confirm the agreement between the undersigned (the “Trust”) and you (the “Distributor”) as follows:

1. The Trust is an open-end investment company organized as a Massachusetts business trust and consisting of such separate investment portfolios as have been or may be established by the Trustees of the Trust from time to time. A separate series of shares of beneficial interest in the Trust is offered to investors with respect to each investment portfolio. The PIMCO Global Multi-Asset Fund and PIMCO EM Fundamental IndexPLUS TR Strategy Fund (the “Funds”) and PIMCO Long Duration Corporate Bond Portfolio (the “Portfolio”) are each a separate investment portfolio of the Trust.

2. The Trust and the Distributor have entered into an Amended and Restated Distribution Contract (the “Contract”) dated February 26, 2008, pursuant to which the Distributor has agreed to be the distributor of shares of the Trust.

3. As provided in paragraph 1 of the Contract, the Distributor hereby adopts the Contract with respect to the Funds and the Portfolio and the Distributor hereby acknowledges that the Contract shall pertain to the Funds and the Portfolio, the terms and conditions of such Contract being hereby incorporated herein by reference.

4. This Supplement and the Contract shall become effective with respect to the Funds, the Portfolio and each class thereof on August 12, 2008 and shall continue in effect for a period not to exceed one year from the effective date of this Supplement and shall continue thereafter on an annual basis with respect to the Funds, the Portfolio and each class thereof only so long as such continuance is specifically approved at least annually by (a) the Trust’s Board of Trustees or, with respect to the Funds, the Portfolio and each class thereof, by the vote of a majority of the outstanding voting securities of the Funds or the Portfolio, as applicable (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)), and each class thereof and (b) by the vote, cast in person at a meeting called for the purpose, of a majority of the Trust’s Trustees who are not parties to this Contract or “interested persons” (as defined in the 1940 Act) of any such party. This Contract shall terminate automatically in the event of its assignment (as defined in the 1940 Act). This Contract may, in any event, be terminated at any time without the payment of any penalty, by the Funds, the Portfolio or class thereof or the Distributor upon not more than 60 days’ and not less than 30 days’ written notice to the other party.

5. The Trust and the Distributor hereby agree to amend the Contract as of the date hereof to add the Funds and the Portfolio to Schedule A and to make other changes to Schedule A. Accordingly, the current Schedule A is replaced with the new Schedule A attached hereto.

6. The Declaration of Trust establishing the Trust, as amended and restated effective March 31, 2000, a copy of which, together with all amendments thereto (the “Declaration”), is on file in the Office of the Secretary of the Commonwealth of Massachusetts, provides that the name “PIMCO Funds” refers to the trustees under the Declaration collectively as trustees and not as individuals or personally, and that no shareholder, trustee, officer, employee or agent of the Trust shall be subject to claims against or obligations of the Trust to any extent whatsoever, but that the Trust estate only shall be liable.

If the foregoing correctly sets forth the agreement between the Trust and the Distributor, please so indicate by signing and returning to the Trust the enclosed copy hereof.

Very truly yours,
PIMCO FUNDS
