diversify investments in your individual accounts, obtain a loan from the plan,
or obtain a distribution from the plan. This period, during which you will be
unable to exercise these rights otherwise available under the plan, is called a
blackout period. Whether or not you are planning retirement in the near
future, we encourage you to carefully consider how this blackout period may
affect your retirement planning, as well as your overall financial plan.

3. The blackout period for the plan is expected to begin and end as follows:

|* |  | Please note that if you need to complete paperwork for any
distribution or loan requests (including spousal consents as
applicable), we recommend that you request the appropriate paperwork
package by December 8, 2003 in order to ensure you have enough time to
receive the package in the mail, complete the paperwork, and return it
to CitiStreet (the current recordkeeper) on or before the start date of
the applicable blackout period listed above.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|** |  | Please note that hardship requests and associated paperwork must be
provided to the Sun Life Financial Human Resources department in a
timely manner to ensure that your distribution will process on or
before the December 19 start date.
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

4. During the blackout period you will be unable to direct or diversify the
assets held in your plan account. For this reason, it is very important that
you review and consider the appropriateness of your current investments in
light of your inability to direct or diversify those investments during the
blackout period. For your long-term retirement security, you should give
careful consideration to the importance of a well-balanced and diversified
investment portfolio, taking into account all your assets, income and
investments. In connection with the Sun Life Financial Stock Fund, you should
be aware that there is a risk to holding substantial portions of your assets in
the securities of any one company, as individual securities tend to have wider
price swings, up and down, in short periods of time, than investments in
diversified funds. Stocks that have wide price swings might have a large loss
during the blackout period, and you would not be able to direct the sale of
such stocks from your account during the blackout period.

5. If you have any questions concerning this notice, you should contact Mike
Gentile, Sr. Human Resources Manager, Sun Life Assurance Company of Canada
(U.S.), SC3040, One Sun Life Executive Park, Wellesley Hills, MA 02481, phone
800-432-1102, extension 1065.
