Dear DG Shareholder:

The Board of Trustees of the DG Investor Series has called a special
shareholders meeting concerning matters that are important to you.

As you may be aware, Deposit Guaranty Corp. completed a merger with and into
First American Corporation on May 1, 1998. As a result, the new organization has
since taken steps to consolidate the mutual fund investment advisory activities
of both banks under one umbrella. We believe that these actions will result in
positive benefits for DG shareholders.

As the next step in the consolidation process, you are asked to vote on the
approval of the reorganization of the DG Investor Series into the AmeriStar
Portfolios of The Infinity Mutual Funds, Inc. As part of the reorganization, the
newly combined funds will be renamed the ISG FUNDS. Upon completion of the
proposed reorganization, the ISG Funds will consist of 19 funds with over $2.6
billion in assets.

WHAT DO THESE CHANGES MEAN TO YOU?

o        The aggregate value of the shares you held before the reorganization
         will not change and will be the same immediately after the
         reorganization.
o        The reorganization will be tax-free and will not involve
         any sales loads, commissions or  transaction charges.
o        The investment objectives and policies of your fund will be
         substantially similar to your fund's current objectives and policies
         except as stated in the enclosures.

         KEY BENEFITS OF THE REORGANIZATION:

o        Substantial increase in the number of fund choices available to you.
o        Enhanced investment management expertise and improved research 
         capabilities.
o        Improved shareholder servicing and the elimination of redundant 
         administration costs to the funds.
o        Greater efficiencies in the operational management of the funds.

As a result, the DG Investor Series' Board of Trustees has voted in favor of the
proposed reorganization and strongly encourages that you vote "For" the proposal
as well. The reorganization and other related matters are discussed in detail in
the enclosed materials, which you should read carefully.

FUND COMBINATIONS AND NEW FUND NAMES:

In connection with the reorganization of the DG Investor Series, each DG Fund
listed below will transfer all of its assets and liabilities to the indicated
ISG Fund in exchange for Shares of such ISG Fund, assuming that the
reorganization is approved by shareholders. This transaction is described in
detail in the enclosed materials, which you should read carefully.
