Dear Shareholder:

In April you received proxy voting materials regarding a proposal to change the
Declarations of Trust for the IXIS Advisor Funds and Loomis Sayles Funds. The
Special Meeting of Shareholders was held on June 2, 2005 and was adjourned to
allow for the solicitation of additional necessary votes. The meeting has been
rescheduled for June 22, 2005.

To date, we have not received your vote. Please take a few minutes to review the
information provided in this letter and vote your shares. We cannot emphasize
enough the importance of your vote, regardless of how many shares you own.
Voting promptly also is important as the rescheduled meeting date is June 22. If
we do not receive enough votes by that date, we may have to resolicit
shareholders. Please help your fund avoid the expense of additional solicitation
by voting today.

The Agreement and Declarations of Trust for each Trust governs the basic
operations of the Trusts. Shareholder approval is required for certain changes.
The changes described in the proxy statement you received in April are intended
to modernize the Declarations of Trust to accommodate changes in law or practice
since the Declarations of Trust were last approved by shareholders, as well as
to make the Declarations of Trust uniform across the Trusts. We anticipate that
the overall effect of these changes will reduce costs and expenses in the
administration of the Funds and provide more flexibility for the operations of
the Funds, within limits of applicable law.

Vote by toll-free telephone, Internet or mail
Voting by toll-free telephone or via the Internet is the quickest way to
register your vote before the meeting. Of course, you also may vote by returning
the enclosed proxy card. A self-addressed, postage-paid envelope has been
enclosed for your convenience. Please see the enclosed proxy card for more
information and voting instructions. If you do vote via the Internet or by
telephone, you do not need to mail your proxy card. If you want to change your
vote, you may do so using any of these methods. A proxy solicitation firm, Alamo
Direct, may call to remind you to return your proxy.

Thank you for your cooperation in voting on this important proposal. If you have
questions, please call your financial representative.
Sincerely,


John T. Hailer                                  Robert Blanding
