Dear Ms. Garcia:

         This letter will memorialize our mutual agreement to amend Schedule I
to the above-referenced Sub-Investment Management Agreement relating to the
Large Cap Value CORE Portfolio, to adjust the current fee schedule, effective as
of July 1, 2001. Attached is a revised copy of Schedule I which maintains a 40
basis point charge for the first $50 million of Net Assets, maintains a 30 basis
point charge for the next $150 million, introduces a 25 basis point charge for
the next $800 million and introduces a 20 basis point charge for amounts over $1
billion. Please substitute copies of the attached Schedule I for the old copies
of Schedule I in your files.

         Kindly acknowledge receipt of this letter and the attachment, and
indicate your agreement to the amendment of Schedule I, by signing and returning
the duplicate of this letter. Thank you.
