The Fund was notified by Santander Global Advisors, Inc. ("Santander"),

Santander effective no later than January 24, 2000. The Board also
voted, subject to approval by the shareholders of the Portfolio at a

same. All references to the "Santander International Stock Portfolio"
in the Prospectus should be changed to "Putnam International Stock
Portfolio." The Fund has been informed that the Insurance Companies (as

communications with Contract owners and prospective Contract owners
until they are able to revise such documents.
The paragraph entitled "Principal investment strategies:" under the
heading "About the Santander International Stock Portfolio" on page 4
of the prospectus is changed to read as follows:
"The Portfolio normally invests mostly in the common stocks of
companies outside the United States. The portfolio manager selects
countries and industries it believes are attractive. The portfolio
manager then seeks stocks offering opportunity for gain. These may
include both growth and value stocks. The Portfolio invests mainly in
mid-sized and large companies, although the Portfolio can invest in
companies of any size. The Portfolio will usually be invested in
issuers located in at least three countries, not including the U.S.
Under normal conditions, the Portfolio will not invest more than 15% of
its net assets in the
