                  continue in effect until March 31, 2008 and thereafter for
                  successive twelve-month periods (computed from each April

                  respect to each Portfolio, this Agreement may be terminated at
                  any time, without the payment of any penalty, (i) by vote of a
                  majority of the outstanding voting securities of each
                  respective Portfolio voting separately, as defined in the 1940
                  Act, or (ii) by a vote of a majority of our entire Board of
                  Trustees, on sixty days' written notice to you, or by you on
                  sixty days' written notice to us."
