(1) These expenses are annualized. The Fund began operations on June 17, 1999.
(2) The Fund's Class 2 distribution plan or "Rule 12b-1 Plan" is described in
the Fund's prospectus. While the maximum amount payable under the Fund's
Class 2 Rule 12b-1 Plan is 0.35% per year of the Fund's average daily net
assets, the Board of Trustees of Franklin Templeton Variable Insurance
Products Trust has set the current rate at 0.25% per year through at least
April 30, 2001.
(3) The fund administration fee is paid indirectly through the management fee.
(4) On 2/8/00, a merger and reorganization was approved that combined the
Franklin Small Cap Fund with a similar fund of the Templeton Variable
Products Series Fund, effective 5/1/00. On 2/8/00, fund shareholders
approved new management fees, which apply to the combined fund effective
5/1/00. The table shows restated total expenses based on the new fees and
assets of the fund as of 12/31/99, and not the assets of the combined fund.
However, if the table reflected both the new fees and the combined assets,
<PAGE>
the fund's expenses after 5/1/00 would be estimated as: Management Fees
0.55%, Distribution and Service Fees 0.25%, Other Expenses 0.27%, and Total
Fund Operating Expenses 1.07%.
(5) The management fees shown are based on the fund's maximum contractual
amount. Other expenses are estimated. The manager and administrator have
agreed in advance to waive or limit their respective fees and to assume as
their own expense certain expenses otherwise payable by the fund so that
Total Fund Operating Expenses do not exceed 0.75% of average net assets for
the current fiscal year. After December 31, 2001, the manager and
administrator may end this arrangement at any time. Without this reduction
Total Fund Operating Expenses were:

(6) The management fees shown are based on the fund's maximum contractual
amount. Other expenses are estimated. The manager and administrator have
agreed in advance to waive or limit their respective fees and to assume as
their own expense certain expenses otherwise payable by the fund so that
Total Fund Operating Expenses do not exceed 1.30% of average net assets,
including Class 2's 12b-1 plan fee, for the current fiscal year. After
December 31, 2001, the manager and administrator may end this arrangement at
any time.
(7) Each Series has an expense offset arrangement which reduces the series'
custodian fee based upon the amount of cash maintained by the series with
its custodian and dividend disbursing agent. Each series may enter into
other such arrangements and directed brokerage arrangements, which would
also have the effect of reducing the series' expenses. After these
reductions, the Total Fund Operating Expenses would be:

(8) MFS has contractually agreed, subject to reimbursement, to bear expenses for
these series such that each such series' "Other Expenses" (after taking into
account the expense offset arrangement described above), do not exceed 0.15%
of the average daily net assets of the series during the current fiscal
year. These contractual fee arrangements will continue until at least May 1,
2001, unless changed with the consent of the board of trustees which
oversees the series. Without this waiver, "Total Fund Operating Expenses"
would have been:
