AMENDMENT NO. 33

TO THE DECLARATION OF TRUST OF

NORTHERN INSTITUTIONAL FUNDS

(a Delaware statutory trust)

This Amendment No. 33 (the “Amendment”) to the Agreement and Declaration of Trust of Northern Institutional Funds (the “Trust”) amends, effective May 18, 2023, the Agreement and Declaration of Trust of the Trust dated as of July 1, 1997, as amended (the “Declaration of Trust”).

WHEREAS, on May 18, 2023, the Board of Trustees of the Trust unanimously voted to amend the Declaration of Trust to remove Article VIII, Section 2 of the Declaration of Trust in order to eliminate the possibility that the Section could be construed as permitting an additional payment by, or assessment on, shareholders of the Trust solely by reason of their ownership of Trust shares;

NOW, THEREFORE, the Declaration of Trust is hereby amended as follows:
