     Funds,  a fee equal to 75 basis  points  (0.75%)  per annum of the  average

c.   APPLICABILITY  TO NEW FUNDS. If the Issuer desires to add additional  funds
     to the Plan,  whether  currently-existing  or created in the future (a "New
     Fund"),  and the Issuer's  Board of Trustees (the "Board") has approved the
     Plan for such New Fund in the  manner  set forth in SECTION 5 of this Plan,
     as well as by the then-sole  shareholder  of the C Class shares of such New
     Fund (if required by the Investment Company Act of 1940 (the "1940 Act") or
     rules  promulgated under the 1940 Act), this Plan may be amended to provide
     that  such New  Fund  will  become  subject  to this  Plan and will pay the
     Distribution  Fee and the  Shareholder  Services  Fee set forth in SECTIONS
     1(A) AND 1(B)  above,  unless  the  Board  specifies  otherwise.  After the

     to include such New Fund.

d.   CALCULATION AND ASSESSMENT.  Distribution  Fees and Individual  Shareholder

     the definition of "service fees" hereunder, or if the NASD adopts a related
     definition intended to define the same concept,  the definition of "service
     fees" in this  Section  shall be  automatically  amended,  without  further
     action of the  parties,  to conform to such NASD  definition.  Overhead and
     other expenses of Distributor related to its service activities,  including
