     All Trustees serve as Trustees of 43 funds within the MFS fund complex
advised by Massachusetts Financial Services Company ("MFS" or the "Adviser"),
investment adviser to the Trust, except for Messrs. Bailey and Scott, who each
serve as Trustees of 74 funds within the MFS fund complex, and Mr. Shames, who
serves as a Trustee of 132 funds within the MFS fund complex. Messrs. Scott and
Shames are "interested persons" (as defined under the 1940 Act) of the Trust
because they are each an officer and director of MFS; Messrs. Scott and Shames
each own shares of common stock of MFS. Mr. Bailey is considered an "interested
person" of the Trust because he is a director of Sun Life Assurance Company of
Canada (U.S.), an affiliate of MFS.


     The Trust pays each Trustee who is not an officer of MFS a fee of $8,275
per year, plus $500 per meeting and $500 per committee meeting attended,
together with such Trustee's actual out-of-pocket expenses relating to
attendance at meetings. In addition, each Trustee who is not an officer of the
Adviser will be entitled to receive certain benefits pursuant to the Trust's
retirement plan. Under this plan, each such Trustee (or his or her
beneficiaries) will be entitled to receive an annual retirement or death benefit
in an amount of up to 50% of such Trustee's average annual compensation,
depending on the Trustee's length of service. Set forth below is certain
information concerning the cash compensation paid to these Trustees and benefits
accrued, and estimated benefits payable, under the retirement plan.

(4) Other funds in the MFS fund complex provide similar retirement benefits to
    the Trustees.

     The Board of Trustees of the Trust met 6 times during its last fiscal year.
The Board has a standing Audit Committee, composed of Messrs. Cohan, Robb,
Sherratt and Smith to review the internal and external accounting and auditing
procedures of the Trust and, among other things, to consider the selection of
independent public accountants for the Trust, to approve all significant
services proposed to be performed by its independent public accountants and to
consider the possible effect of such services on their independence. The Audit
Committee met 4 times during the Trust's last fiscal year. The Board has created
a Nominating Committee, composed of Ms. O'Neill and Messrs. Cohan, Cohn,
Gibbons, Robb, Sherratt and Smith, that is responsible for recommending
qualified candidates to the Board in the event that a position is vacated or
created. The Nominating Committee consists only of Trustees who are not
"interested persons" of the Trust as defined in the 1940 Act. The Nominating
Committee would consider recommendations by shareholders if a vacancy were to
exist. The Board currently expects to reduce the size of the Board upon the
retirements disclosed above in order to eliminate the vacancies created thereby.
Shareholders wishing to recommend Trustee candidates for consideration by the
Nominating Committee may do so by writing the Secretary of the Trust. Nominees
must be persons who are not "interested persons" of the Trust as defined in the
1940 Act. Members of the Nominating Committee confer periodically and hold
meetings as required. The Nominating Committee did not meet during the Trust's
last fiscal year.


Required Vote. Approval of this matter as to any nominee will require the
affirmative vote of a plurality of the Trust's outstanding shares voting at the
Meeting in person or by proxy.

ITEM 2--RATIFICATION OF SELECTION OF ACCOUNTANTS

     It is intended that proxies not limited to the contrary will be voted in
favor of ratifying the selection, by a majority of Trustees who are not
"interested persons" (as defined in the 1940 Act) of the Trust, of Ernst & Young
LLP under Section 32(a) of the 1940 Act as independent public accountants to
certify every financial statement of the Trust required by any law or regulation
to be certified by independent public accountants and filed with the SEC and to
provide certain other tax-related services (such as tax return preparation and
assistance and consultation with respect to the preparation of filings with the
SEC) in respect of all or any part of the fiscal year ending November 30, 1999
Ernst & Young LLP has no direct or material indirect interest in the Trust.

     Representatives of Ernst & Young LLP are expected to be present at the
Meeting and will have an opportunity to make a statement if they desire to do
so. Such representatives are also expected to be available to respond to
appropriate questions.


                                       4


Required Vote. Ratification of this matter will require the affirmative vote of
a majority of the Trust's outstanding shares voting at the Meeting on this
matter in person or by proxy.

INVESTMENT ADVISER AND ADMINISTRATOR

     The Trust engages as its investment adviser and administrator MFS, a
Delaware corporation, with offices at 500 Boylston Street, Boston, MA 02116. MFS
is a subsidiary of Sun Life of Canada (U.S.) Financial Services Holdings, Inc.,
One Sun Life Executive Park, Wellesley Hills, Massachusetts 02481, which is in
turn an indirect wholly owned subsidiary of Sun Life Assurance Company of
Canada, 150 King Street West, Toronto, Canada M5H1J9.


MANNER OF VOTING PROXIES

     All proxies received by the management will be voted on all matters
presented at the Meeting, and if not limited to the contrary, will be voted FOR
the election of Messrs. Bailey, Shames and Sherratt as Trustees of the Trust (if
still available for election), and ratification of the selection of Ernst &
Young LLP as independent public accountants.

     All proxies voted, including proxies that reflect abstentions or the
withholding of authority to vote for a nominee for election as Trustee, will be
counted toward establishing a quorum. A majority of the Trust's outstanding
shares entitled to be cast on a particular matter, present in person or
represented by proxy, constitutes a quorum as to such matter. Passage of any
proposal being considered at the Meeting will occur only if a sufficient number
of votes are cast FOR the proposal. With respect to the election of Trustees and
the ratification of public accountants, neither withholding authority to vote
nor abstentions have any effect on the outcome of the voting on either item.


     The Trust knows of no other matters to be brought before the Meeting. If,
however, because of any unexpected occurrence, any nominee is not available for
election or if any other matter properly comes before the Meeting, it is the
Trust's intention that proxies not limited to the contrary will be voted in
accordance with the judgment of the persons named in the enclosed form of proxy.

SUBMISSION OF CERTAIN PROPOSALS

     Proposals of shareholders which are intended to be presented at the 2000
Annual Meeting of Shareholders must be received by the Trust on or prior to May
6, 2000.


SECTION 16(a)-BENEFICIAL OWNERSHIP REPORTING REQUIREMENTS Section 16(a) of the
     Securities Exchange Act of 1934 requires Trustees,
directors and certain officers of the Trust and MFS, and persons who own more
than ten percent of the Trust's shares, to file reports of ownership and changes
in ownership with the SEC and the New York Stock Exchange. Such persons are
required by SEC regulation to furnish the Trust with copies of all Section 16(a)
forms they file.


     Based solely on review of the copies of Forms 3, 4 and 5 and amendments
thereto furnished to the Trust with respect to its most recent fiscal year, or
written representations that no Forms 5 were required, the Trust believes that,
during the year ended November 30, 1998, all Section 16(a) filing requirements
applicable to Trustees, directors and certain officers of the Trust and the
Adviser and greater than ten percent beneficial owners were complied with.



                                       5


ADDITIONAL INFORMATION

     To obtain the necessary representation at the Meeting, solicitations may be
made by mail, telephone or interview by Corporate Investor Communications, Inc.
("CIC") or its agents, as well as by officers of the Trust, employees of the
Adviser and securities dealers by whom shares of the Trust have been sold. It is
anticipated that the total cost of any such solicitations, if made by CIC or its
agents, would be approximately $9,500 plus out-of-pocket expenses, and if made
by any other party, would be nominal.

     The expense of solicitations as well as the preparation, printing and
mailing of the enclosed form of proxy, and this Notice and Proxy Statement, will
be borne by the Trust.

                IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY
