Dear Shareholder:

I am writing to ask for your vote on important matters affecting your fund.

A shareholders' meeting is scheduled for Wednesday, March 23, 2005. At the
meeting, all shareholders are being asked to vote on the election of trustees.
In addition, shareholders of Massachusetts Investors Growth Stock Fund and
MFS(R) Municipal Limited Maturity Fund are being asked to vote on proposals
regarding those funds' investment policies.

While you are, of course, welcome to join us at the shareholders' meeting on
March 23, 2005, most shareholders vote by telephone, over the Internet, or by
filling out, signing, and returning the enclosed proxy card.

Your vote makes a difference. No matter what the size of your investment, your
vote is important. The trustees of your fund recommend that you vote for the
proposals, but however you decide to vote, it is important that you take the
time to do so. By voting early, you can help save your fund the expense of
additional mailings to solicit shareholder votes.

Information regarding the proposals is available in the proxy statement. There
are three convenient ways to vote: by telephone, over the Internet, or by
filling out, signing and returning the enclosed proxy card. Voting instructions
are provided on the proxy card.

If you have any questions, please contact your investment professional. For
questions regarding the election of trustees only, call 1-877-383-7949 any
business day from 8 a.m. to 8 p.m. Eastern time. For questions regarding the
investment policy proposals only, call Georgeson Shareholder Communications at
1-877-288-6189. Thank you for your prompt vote.

    Sincerely,

/s/ Robert J. Manning

    President
    MFS Family of Funds(R)
