                 and regulations, the Company intends to purchase Administrative
                 Class shares in the Portfolios listed in Schedule A hereto, as
                 it may be amended from time to time by mutual written agreement
                 (the "Designated Portfolios") on behalf of the Account to fund
                 the aforesaid Contracts, and the Underwriter is authorized to
                 sell such shares to the Account at net asset value;"

This Amendment No. 1 may be executed simultaneously in two or more counterparts,
each of which taken together shall constitute one and the same instrument.
