SunAmerica Series Trust
Supplement to the Prospectus dated March 30, 1999
The following replaces the first paragraph under the "ACCOUNT
INFORMATION" section on page 29 of the Prospectus:
Shares of the Portfolios are not offered directly to the public.
Instead, shares are currently issued and redeemed only in
connection with investments in and payments under variable
annuity contracts and variable life insurance policies (Variable
Contracts) of Anchor National Life Insurance Company, First
SunAmerica Life Insurance Company, AIG Life Insurance Company and
American International Life Assurance Company of New York (Life
Companies), each of which is affiliated with the Trusts investment
adviser and manager, SunAmerica Asset Management Corp. (SAAMCo). All
shares of the Trust are owned by "Separate Accounts" of the Life
Companies. So if you would like to invest in a Portfolio, you must
purchase a Variable Contract from one of the Life Companies. You
should be aware that the contracts involve fees and expenses that are
not described in this Prospectus, and that the contracts also may
involve certain restrictions and limitations. Certain Portfolios may
not be available in connection with a particular contract. You will
find information about purchasing a Variable Contract and the
Portfolios available to you in the prospectus that offers the
contracts, which accompanies this Prospectus.
