VIL acknowledges that: (1) it shall not be entitled to collect on or make a claim for waived fees at any time in the future; and (2) it shall not be entitled to collect on or make a claim for reimbursed expenses at any time in the future.

The operating expense limits set out above apply only at the Fund level and do not limit the fees payable by the underlying investment companies in which the Index Solution Portfolios invest. Therefore, VPI acknowledges and agrees that the Class Z shares of the Index Solution Portfolios will indirectly bear Acquired Fund Fee and Expenses.
