Dear Ms. Emory:

         This letter will memorialize our mutual agreement to amend Schedule I
to the above-referenced Sub-Investment Management Agreement, relating to the
International Opportunities Portfolio, to adjust the current fee schedule
effective as of July 1, 2001. Attached is a revised copy of Schedule I which
caps the 50 basis point charge when amounts under management are $500 million
and introduces a 45 basis point charge for all amounts under management when Net
Assets are $500 million or more.

         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.
