The undersigned, constituting at least a majority of the Trustees of AMG Funds II (the “Trust”), a business trust organized under the laws of The Commonwealth of Massachusetts, do hereby amend the Amended and Restated Declaration of Trust of the Trust dated March 19, 1992, as amended from time to time (the “Declaration of Trust”), as follows:

The foregoing amendment may be signed in counterparts with the same effect as if all signatories had signed the same document. All such counterparts shall be deemed an original, shall be construed together and shall constitute one and the same instrument.
