2. Allocation of Charges and Expenses.  Touchstone shall pay the entire salaries
and wages of all of the Trust's Trustees, officers and agents who devote part or

and salaries of such persons shall not be deemed to be expenses  incurred by the
Trust.
3. Operating Expense Waivers or  Reimbursement.  Touchstone shall waive all or a
portion of its fee pursuant to this  and/or reimburse a portion
of the operating expenses (including  amortization of organization  expense, but
excluding interest, taxes, brokerage commissions and other portfolio transaction
expenses,  capital expenditures and extraordinary  expenses) ("Expenses") of the
Fund such that after such  reimbursement the aggregate Expenses of each class of
the Fund  shall be equal on an annual  basis to 0.90% of the  average  daily net
assets of Class A shares  and 1.65% of the  average  daily net assets of Class C
shares for the Fund's then-current fiscal year.
         Touchstone's  obligations  in this  Section 3 may be  terminated,  with

4.        Compensation of Touchstone.  For the services to be rendered, the
facilities to be provided and the expenses to be assumed by Touchstone
hereunder, the Fund shall pay to Touchstone a sponsor fee equal on an annual
basis to 0.20% of the Fund's average daily net assets for its then-current

If Touchstone serves under this Agreement for less than the whole of any month,
the compensation to Touchstone hereunder shall be prorated.  For  purposes  of
computing the fees payable to Touchstone  hereunder,  the net asset value of the
Fund shall be  computed  in the  manner  specified  in the  Fund's  then-current

the Fund until December 31, 2000.
         5.  Limitation  of Liability  of  Touchstone.  Touchstone  shall not be

         it is terminating this Agreement as to the Fund or (ii) at such time as
         Touchstone ceases to be the investment advisor to the Fund.  In the
         event of a termination pursuant to clause (i) of the preceding
         sentence, each party's obligations hereunder shall terminate as to the
         Fund as of the end of the calendar quarter in which the notice of
         termination is given; in the event of a termination pursuant to
         clause (ii) of the preceding sentence, Touchstone's obligations
         hereunder shall terminate as to the Fund as of the effective date of
         its termination as investment advisor.
                  (b) by  the  Board,  or by  the  vote  of a  "majority  of the
         outstanding  voting  securities" (as such phrase is defined in the ▇▇▇▇

         the Trust,  on behalf of the Fund,  has given at least 30 days' advance
         written notice to Touchstone that it is terminating this Agreement.
          8.        Subcontracting by Touchstone.  Touchstone may subcontract
for the performance of Touchstone's obligations hereunder with any one or more
persons; provided, however, that Touchstone shall be as fully responsible to the
Trust for the acts and omissions of any subcontractor as it would be for its own
acts or omissions.
          9.      Severability.  If any provision of this Agreement shall become
or shall be found to be invalidby a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.
