Supplement to the April 1, 1998 Prospectus and Statement of Additional
Information (as revised November 13, 1998)
The following information should be read in conjunction with the Fund's
Prospectus and Statement of Additional Information ("SAI"), dated April 1, 1998,
and contains a description of Class I shares.
Class I shares are available for purchase only by certain investors as
described under the caption "Eligible Purchasers" below. As of November 1, 1998
the Expense Summary table is revised as follows:

(1) The Fund has an expense offset arrangement which reduces the Fund's
custodian fee based upon the amount of cash maintained by the Fund with its
custodian and dividend disbursing agent, and may enter into other such
arrangements and directed brokerage arrangements (which would also have the
effect of reducing the Fund's expenses). Any such fee reductions are not
reflected under "Other Expenses."
Example of Expenses
An investor would pay the following dollar amounts of expenses on a $1,000
investment in Class I shares of the Fund, assuming (a) a 5% annual return and
(b) redemption at the end of each of the time periods indicated:
Period Class I

The purpose of the expense table above is to assist investors in
understanding the various costs and expenses that a shareholder of the Fund will
bear directly or indirectly. A more complete description of the Fund's
management fee is set forth under the caption "Management of the Fund" in the
Prospectus.

ELIGIBLE PURCHASERS
Class I shares are available for purchase only by the following purchasers
("Eligible Purchasers"):
(i) certain retirement plans established for the benefit of employees of
Massachusetts Financial Services Company ("MFS"), the Fund's investment
adviser, and employees of MFS' affiliates;
(ii) any fund distributed by MFS Fund Distributors, Inc. ("MFD"), the Fund's
distributor, if the fund seeks to achieve its investment objective by
investing primarily in shares of the Fund and other funds distributed by
MFD;
(iii)any retirement plan, endowment or foundation which (a) purchases shares
directly through MFD (rather than through a third party broker or dealer or
other financial intermediary); (b) has, at the time of purchase of Class I
shares, aggregate assets of at least $100 million; and (c) invests at least
$10 million in Class I shares of the Fund either alone or in combination
with investments in Class I shares of other MFS funds distributed by MFD
(additional investments may be made in any amount); provided that MFD may
accept purchases from smaller plans, endowments or foundations or in
smaller amounts if it believes, in its sole discretion, that such entity's
aggregate assets will equal or exceed $100 million, or that such entity
will make additional investments which will cause its total investment to
equal or exceed $10 million, within a reasonable period of time;
(iv) bank trust departments or law firms acting as trustee or manager for trust
accounts which initially invest, on behalf of their trust clients, at least
$100,000 in Class I shares of the Fund (additional investments may be made
in any amount); provided that MFD may accept smaller initial purchases if
it believes, in its sole discretion, that the bank trust department or law
firm will make additional investments, on behalf of its trust clients,
which will cause its total investment to equal or exceed $100,000 within a
reasonable period of time; and
(v) certain retirement plans offered, administered or sponsored by insurance
companies, provided that these plans and insurance companies meet certain
criteria established by MFD from time to time.
In no event will the Fund, MFS, MFD or any of their affiliates pay any sales
commissions or compensation to any third party in connection with the sale of
Class I shares; the payment of any such sales commission or compensation would,
under the Fund's policies, disqualify the purchaser as an eligible investor of
Class I shares.
SHARE CLASSES OFFERED BY THE FUND
Four classes of shares of the Fund currently are offered for sale, Class A
shares, Class B shares, Class C shares and Class I shares. Class I shares are
available for purchase only by Eligible Purchasers, as defined above, and are
described in this Supplement. Class A shares, Class B shares and Class C shares
are described in the Fund's Prospectus and are available for purchase by the
general public.
Class A shares are offered at net asset value plus an initial sales charge
up to a maximum of 5.75% of the offering price (or a contingent deferred sales
charge (a "CDSC") of 1.00% upon redemption during the first year in the case of
purchases of $1 million or more and certain purchases by retirement plans), and
are subject to an annual distribution fee and service fee up to a maximum of
0.35% per annum. Class B shares are offered at net asset value without an
initial sales charge but are subject to a CDSC upon redemption (declining from
4.00% during the first year to 0% after six years) and an annual distribution
fee and service fee up to a maximum of 1.00% per annum; Class B shares convert
to Class A shares approximately eight years after purchase. Class C shares are
offered at net asset value without an initial sales charge but are subject to a
CDSC of 1.00% upon redemption during the first year and an annual distribution
fee and service fee up to a maximum of 1.00% per annum. Class I shares are
offered at net asset value without an initial sales charge or CDSC and are not
subject to a distribution or service fee. Class C and Class I shares do not
convert to any other class of shares of the Fund.
OTHER INFORMATION
Eligible Purchasers, as defined above, may exchange Class I shares of the
Fund for Class I shares of any other Fund available for purchase by such
Eligible Purchasers at their net asset value (if available for sale), and may
exchange Class I shares of the Fund for shares of the MFS Money Market Fund (if
available for sale), and may redeem Class I shares of the Fund at net asset
value. Distributions paid by the Fund with respect to Class I shares generally
will be greater than those paid with respect to Class A shares, Class B shares
and Class C shares because expenses attributable to Class A shares, Class B
shares and Class C shares generally will be higher.
The date of this Supplement is July 16, 1998 (as revised November 13, 1998).
