DREYFUS INSTITUTIONAL RESERVES FUNDS

Rule 18f-3 Plan

Rule 18f-3 under the Investment Company Act of 1940, as amended (the "1940 Act"), requires that the Board of an investment company desiring to offer multiple classes pursuant to said Rule adopt a plan setting forth the separate arrangement and expense allocation of each class, and any related conversion features or exchange privileges.

Dreyfus Institutional Reserves Funds (the "Trust"), on behalf of its series listed on Schedule A attached hereto, as such Schedule may be revised from time to time (each, a "Fund"), desires to offer multiple classes in accordance with Rule 18f-3, and the Trust's Board, including a majority of the Board members who are not "interested persons" (as defined in the 1940 Act), has determined that the following plan is in the best interests of each class individually and the Fund as a whole:

1.   Class Designation:  Fund shares shall be divided into Institutional shares, Hamilton shares and Premier shares.

2.   Differences in Services:  The services offered to shareholders of each Class, as described in the Funds' prospectuses or statement of additional information, shall be substantially the same, except for the level of certain services provided to holders of Hamilton shares and Premier shares pursuant to a Shareholder Services Plan and to holders of Premier shares pursuant to an Administrative Services Plan.

Hamilton shares and Premier shares shall be subject to an annual service fee at the rate set forth on Schedule B attached hereto in respect of the provision of personal services to shareholders of such Classes and/or the maintenance of shareholder accounts, pursuant to a Shareholder Services Plan.

Premier shares shall be subject to an annual administrative services fee at the rate set forth on Schedule C attached hereto in respect of the provision of recordkeeping and other related services, pursuant to an Administrative Services Plan.

3.   Distribution Arrangements:  Each Class of shares shall be offered at net asset value as described in the Funds' prospectuses.  No Class shall be subject to any front-end or contingent deferred sales charges.

4.   Expense Allocation:  The following expenses shall be allocated, to the extent practicable, on a Class-by-Class basis:  (a) fees under the Shareholder Services Plan and Administrative Services Plan; (b) printing and postage expenses related to preparing and distributing materials, such as shareholder reports, prospectuses and proxies, to current shareholders of a specific Class; (c) the expense of administrative personnel and services as required to support the shareholders of a specific Class; (d) litigation or other legal expenses relating solely to a specific Class; (e) transfer agent fees identified by the Fund's transfer agent as being attributable to a specific Class; and (f) Board members' fees incurred as a result of issues relating to a specific Class.

5.Conversion Features:  No Class shall be subject to any automatic conversion feature.  Shares of one Class of a Fund may be converted into shares of another Class of the Fund, provided that, if the conversion is requested by a shareholder, the shareholder requesting the conversion meets the eligibility requirements for the purchase of the new Class of shares of the Fund. 

6.   Exchange Privileges:  Shares of a Class shall be exchangeable only for (a) any class of shares of any other Fund, (b) any class of shares of the investment companies listed on Schedule D attached hereto and (c) shares of certain other investment companies specified from time to time.
