         RE:      CO-ADMINISTRATION SERVICE FEES

                  Ladies and Gentlemen:

This letter constitutes our agreement with respect to compensation to be paid to
PFPC Inc. ("PFPC") under the terms of a Co-Administration Agreement dated June
20, 1995 between you (the "Fund") and PFPC. Pursuant to Paragraph 11 of that
Agreement, and in consideration of the services to be provided to you, on behalf
of the Select Equity Portfolio, Capital Appreciation Portfolio and Small Cap
Value Portfolio (each a "Portfolio" and together the "Portfolios") you will pay
PFPC an annual co-administration fee, to be calculated daily and paid monthly.
You will also reimburse PFPC for its out-of-pocket expenses incurred on behalf
of the Portfolios, including, but not limited to: postage and handling,
telephone, telex, FedEx and outside pricing service charges.

The annual administration and accounting fee with respect to the Select Equity
Portfolio, Capital Appreciation Portfolio and Small Cap Value Portfolio shall be
0.075% of each Portfolio's first $150 million in average daily net assets, 0.06%
of the next $150 million in average daily net assets and 0.05% of average daily
net assets over $300 million.

The fee for the period from the day of the year this agreement is entered into
until the end of that year shall be pro-rated according to the proportion which
such period bears to the full annual period.

If the foregoing accurately sets forth our agreement, and you intend to be
legally bound thereby, please execute a copy of this letter and return it to us.

                                        Very truly yours,

                                        PFPC INC.
