Dear Contract/Policy Owner:

         We are pleased to enclose an Information Statement regarding
Massachusetts Financial Services Company ("MFS") and Jennison Associates LLC
("Jennison"), the new Sub-Advisers of the Select Aggressive Growth Fund (the
"Fund") of Allmerica Investment Trust (the "Trust"), and the new investment
strategies for the Fund. MFS and Jennison were hired effective June 1, 2001 to
replace Nicholas-Applegate Capital Management, L.P. ("Nicholas-Applegate"), the
Fund's previous Sub-Adviser. MFS, with $133 billion in assets under management
as of March 31, 2001, has been managing money since 1924. Jennison had $81
billion in assets under management as of March 31, 2001, and has been managing
money since 1969. Initially each new Sub-Adviser will manage approximately
one-half of the Fund's assets. The investment advisory fees charged by the
Trust's investment manager, Allmerica Financial Investment Management Services,
Inc. ("AFIMS"), to the Fund remain the same. The sub-advisory fees which AFIMS
will pay to MFS and Jennison are less than the sub-advisory fees paid by AFIMS
to Nicholas-Applegate.

         Please take a few minutes to read the Information Statement. It
contains additional information about MFS and Jennison, the terms of the new
Sub-Adviser Agreements, the factors that were considered by management and the
Board of Trustees in making the decision to change Sub-Advisers and a
description of the Fund's new investment strategies.

         This action will not require you to send a proxy and we are not asking
you for a proxy. As always, please feel free to contact your financial
representative or us with any questions or comments you may have.


                                             Sincerely,

                                             /s/ Richard M. Reilly

                                             Richard M. Reilly
                                             President
