</TABLE>
EXPLANATION OF EXPENSE TABLE AND EXAMPLES
1. The purpose of the Expense Table is to show the various expenses you will
incur directly and indirectly by investing in the contract. The Expense
Table reflects expenses of the Separate Account as well as the portfolios.
2. There are situations where all or some of the owner transaction expenses do
not apply. See "Deductions Under the Contracts" for a complete discussion.
3. The examples do not reflect premium taxes that may apply depending on the
state where you live.
4. The examples should not be considered a representation of past or future
expenses. Actual expenses may be greater or less than those shown.
YEAR 2000
Like other insurance, mutual fund, financial and business organizations, and
individuals around the world, SAFECO Life and the Separate Account could be
adversely affected if the computer systems used by SAFECO Life, its principal
underwriter, underlying mutual fund managers and investment advisers, or other
companies that provide services to the Separate Account do not properly process
and calculate date related information from and after January 1, 2000. This is
commonly called the "Year 2000 problem." SAFECO Life is taking steps it believes
are reasonably designed to address the Year 2000 problem with respect to the
computer systems that each of them uses and to obtain satisfactory assurances
that comparable steps are being taken by each of SAFECO Life's other, major
service providers. It is not anticipated that the Separate Account will incur
any charges or that there will be any difficulties in accurate and timely
reporting resulting from the change in year from 1999 to 2000. However, with
approximately 90% of its systems year 2000 ready, SAFECO Life is currently
developing business continuity plans for year 2000 contingencies.
