Re: Fee Waiver/Expense Reimbursement
    --------------------------------

Ladies and Gentlemen:

     CDC IXIS Asset Management Advisers, L.P. ("CDC IXIS Advisers") notifies you
that it will waive its management fee (and, to the extent necessary, bear other
expenses of the Funds listed below) through the date listed below to the extent
that expenses of each class of a Fund, exclusive of brokerage, interest, taxes
and deferred organizational and extraordinary expenses, would exceed the
following annual rates:

            Name of Fund                                 Expense Cap
----------------------------------------    ------------------------------------
June 1, 2003 through April 30, 2004:

     CDC Nvest Strategic Income Fund        1.25% for Class A shares
                                            2.00% for Class B shares
                                            2.00% for Class C shares
                                            1.00% for Class Y shares


     CDC Nvest Growth and Income Fund       1.30% for Class A shares
                                            2.05% for Class B shares
                                            2.05% for Class C shares
                                            1.05% for Class Y shares

     With respect to each Fund, CDC IXIS Advisers shall be permitted to recover
expenses it has borne subsequent to the effective date of this agreement
(whether through reduction of its management fee or otherwise) in later periods
to the extent that a Fund's expenses fall below the annual rates set forth
above. Provided, however, that a Fund is not obligated to pay any such deferred
fees more than one year after the end of the fiscal year in which the fee was
deferred.

     During the periods covered by this letter agreement, the expense cap
arrangement set forth above for each of the Funds may only be modified by mutual
agreement between CDC IXIS Advisers and the Trust after approval by a majority
vote of the "non-interested" Trustees of the Trusts affected.



     For purposes of determining any such waiver or expense reimbursement,
expenses of the class of the Funds shall not reflect the application of balance
credits made available by the Funds' custodian or arrangements under which
broker-dealers that execute portfolio transactions for the Funds' agree to bear
some portion of Fund expenses.

     We understand and intend that you will rely on this undertaking in
preparing and filing the Registration Statements on Form N-1A for the above
referenced Funds with the Securities and Exchange Commission, in accruing each
Fund's expenses for purposes of calculating its net asset value per share and
for other purposes permitted under Form N-1A and/or the Investment Company Act
of 1940, as amended, and expressly permit you to do so.


                                        CDC IXIS Asset Management Advisers, L.P.
