Amendment to Participation Agreement

Allmerica Financial Life Insurance and Annuity Company, Variable Insurance
Products Fund and Fidelity Distributors Corporation, hereby amend their
Participation Agreement, dated May 1, 1991 and as subsequently amended, by
replacing section 2.5 in its entirety with the following:

                2.5. (a) With respect to Initial Class shares, the Fund
         currently does not intend to make any payments to finance distribution
         expenses pursuant to Rule 12b-1 under the 1940 Act or otherwise,
         although it may make such payments in the future. The Fund has adopted
         a "no fee" or "defensive" Rule 12b-1 Plan under which it makes no
         payments for distribution expenses. To the extent that it decides to
         finance distribution expenses pursuant to Rule 12b-1, the Fund
         undertakes to have a board of trustees, a majority of whom are not
         interested persons of the Fund, formulate and approve any plan under
         Rule 12b-1 to finance distribution expenses.

                           (b) With respect to Service Class shares and Service
         Class 2 shares, the Fund has adopted Rule 12b-1 Plans under which it
         makes payments to finance distribution expenses. The Fund represents
         and warrants that it has a board of trustees, a majority of whom are
         not interested persons of the Fund, which has formulated and approved
         each of its Rule 12b-1 Plans to finance distribution expenses of the
         Fund and that any changes to the Fund's Rule 12b-1 Plans will be
         approved by a similarly constituted board of trustees.

IN WITNESS WHEREOF, each party has caused this Amendment to be executed in its
name and on its behalf by its duly authorized representative as of March 29,
2000.
