Unless sooner terminated as provided herein, this Agreement shall continue for an initial one year term and thereafter shall be renewed for successive one-year terms, provided such continuance is specifically approved at least annually by (i) the Funds' board of trustees/directors or (ii) by a vote of a majority (as defined in the Investment Company Act of 1940 Act, as amended ("1940 Act") and Rule 18f-2 thereunder) of the outstanding voting securities of the Funds, provided that in either event the continuance is also approved by a majority of the trustees/directors who are not parties to this Agreement and who are not interested persons (as defined in the 1940 Act) of any party to this Agreement, by vote cast in person at a meeting called for the purpose of voting on such approval. This Agreement is terminable without penalty, on at least sixty (60) days' written notice, by the Funds' board of trustees/directors, by vote of a majority (as defined in the 1940 Act and Rule 18f-2 thereunder) of the outstanding voting securities of the Funds, or by Distributor. This Agreement may be terminated with respect to one or more Funds, or with respect to the entire Fund Company. This Agreement will also terminate automatically in the event of its assignment (as defined in the 1940 Act and the rules thereunder).
