ITEM 1.  TO APPROVE OR DISAPPROVE A NEW INVESTMENT ADVISORY AGREEMENT BETWEEN
         MASSACHUSETTS FINANCIAL SERVICES COMPANY AND THE FUND
GENERAL
The Board of Trustees is proposing that shareholders approve a new Investment
Advisory Agreement (the "New Agreement") with Massachusetts Financial Services
Company, a Delaware corporation ("MFS" or the "Adviser"), the effect of which
would be to increase the rate of compensation payable by the Fund to MFS for
its services as the Fund's investment adviser. The management fee payable by
the Fund has not changed since 1976. If approved by the shareholders, the
management fee payable under the New Agreement will still remain well below
the average advisory fee among a group of comparable growth funds. The
Trustees believe that the rate of compensation under the New Agreement is
reasonable in light of comparative fee information, the Fund's investment
performance, MFS' expenses and profitability in managing the Fund and the
nature, quality and scope of services provided by MFS to the Fund.

BACKGROUND
The Fund has retained MFS to provide it with investment management services
pursuant to an Investment Advisory Agreement dated July 19, 1985 (the "Current
Agreement"). MFS or its predecessors have been the Fund's investment adviser
since 1932. The Current Agreement was most recently approved by the Board of
Trustees, including a majority of the Trustees who are not "interested
persons," as defined in the Investment Company Act of 1940, as amended (the
"1940 Act") (collectively, the "Independent Trustees"), on June 17, 1998 and
by shareholders on May 20, 1982. The New Agreement was approved by the Board
of Trustees, including a majority of the Independent Trustees, on July 15,
1998, subject to shareholder approval. Proxies were last solicited from
shareholders on July 29, 1993 for the purpose of approving the Fund's
conversion to a multiple share class structure.

Pursuant to the Current Agreement, MFS provides the Fund with overall
investment management services, as well as general office facilities. Subject
to such policies as the Board of Trustees may determine, MFS makes investment
decisions for the Fund. For its services and facilities, MFS currently
receives a management fee, computed and paid monthly, in an amount equal to
0.5% of the first $200 million of the Fund's average daily net assets, 0.4% of
the next $300 million of the Fund's average daily net assets and 0.2% of its
average daily net assets in excess of $500 million, in each case on an
annualized basis for the Fund's current fiscal year. For the fiscal year ended
November 30, 1997, MFS received management fees under the Current Agreement of
$4,290,313, equivalent on an annualized basis to 0.28% of the Fund's average
daily net assets (the "Current Effective Fee").

Shareholders of the Fund are being asked to approve the New Agreement,
pursuant to which the investment management fee paid by the Fund to MFS would
be increased from the Current Effective Fee of 0.28% to 0.33% of the Fund's
average daily net assets on an annualized basis (the "Proposed Fee"). This fee
increase is the only material difference between the Current Agreement and the
New Agreement. If approved by shareholders at the Special Meeting, the New
Agreement will become effective on November 1, 1998. If the amendments are not
approved by shareholders, the Current Agreement will continue in effect in its
present form, subject to the continuation and termination provisions contained
therein and described below. A description of the New Agreement and the
services provided by MFS thereunder is set forth below. See "Description of
the New Agreement" below.

In approving the New Agreement and recommending its approval by shareholders,
the Trustees considered the best interests of the shareholders of the Fund,
and took into account all such factors as they deemed relevant. See "Review
Process of the Board of Trustees" below.

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS OF THE FUND
APPROVE THE NEW AGREEMENT.

RATIONALE FOR THE PROPOSAL
At the request of MFS, the Board of Trustees discussed approval of the New
Agreement at meetings held on April 7, 1998, May 20, 1998, June 17, 1998 and
July 15, 1998. In addition, the Independent Trustees also discussed approval
of the New Agreement with their independent counsel at a meeting held on April
23, 1998. In evaluating the New Agreement, the Board of Trustees requested and
received substantial information from MFS to assist in their deliberations.
The Trustees utilized reports sourced by Lipper Analytical Services, Inc.
("Lipper"), a nationally recognized, independent service that monitors mutual
fund expenses and performance, and significant amounts of information
furnished by MFS. The Trustees reviewed these materials and considered various
matters, discussed below, in determining the reasonableness and fairness of
the proposed increase in the management fee payable by the Fund and reached
the following conclusions:

  o The Trustees considered the management fees paid by comparable funds
    available to investors. The Trustees concluded that the current fee rate is
    substantially below average for comparable funds in the Lipper Growth
    category and the Trustees unanimously recommend that it be raised,
    recognizing that the Proposed Fee will remain well below the average for
    comparable funds. The Trustees believe the Proposed Fee is in the best
    interests of the shareholders of the Fund and is reasonable in light of the
    comparative fee information, the Fund's performance, MFS' expenses and
    profitability in managing the Fund and the nature, quality and scope of
    services provided by MFS to the Fund.

  o In today's highly complex investment world, the Trustees and MFS both
    believe an increased fee will help MFS remain competitive in attracting,
    retaining and motivating the top quality investment personnel and other key
    personnel necessary to manage the Fund and provide new and innovative
    services to an expanded shareholder base.

  o The Trustees considered today's ever- expanding securities markets, which
    operate continuously around the globe. The Trustees believe that additional
    resources will help the Adviser maintain state-of-the-art computer systems,
    access information and analyze strategies using the most sophisticated tools
    and methodologies. The Trustees also believe that additional resources are
    needed to administer the Fund by virtue of its size and the growing
    complexities of portfolio transactions domestically and internationally.

The Trustees reached these conclusions after careful discussion and analysis
and believe that they have carefully and thoroughly examined the questions and
alternatives. In recommending that the shareholders of the Fund approve the
New Agreement, the Independent Trustees have considered what they believe to
be the best interests of the shareholders of the Fund. In so doing the
Independent Trustees were advised by independent counsel, retained by the
Independent Trustees and paid by the Fund, as to the nature of the matters to
be considered and the standards to be used in reaching their decision.

REVIEW PROCESS OF THE BOARD OF TRUSTEES
In reaching its decision, the Board of Trustees examined and weighed many
factors, including: (1) the nature, quality and extent of the services
rendered and the results achieved by MFS in the areas of investment management
(including investment performance comparisons with other mutual funds and
certain indices) and administrative services; (2) changes in the mutual fund
industry that have affected the Fund; (3) the payments received by MFS and its
affiliates from all sources involving both the Fund and the other investment
companies advised by MFS; (4) extensive financial, personnel and structural
information as to MFS' organization, including the costs borne by, and
profitability of, MFS and its affiliates in providing service of all types to
the Fund and to the other investment companies advised by MFS; (5) the
organizational capabilities, financial condition and future capital
requirements of MFS; (6) an analysis of the proposed fee rate changes; (7)
information concerning the Fund's expense ratio on both an existing and pro
forma basis; (8) information as to the management fees paid by the other funds
advised by MFS; (9) competitive industry fee structures and expense ratios
including, specifically, the relationship of the proposed management fee rates
to those typically paid by funds with similar investment objectives; (10) a
comparison of the overall profitability of MFS to the profitability of certain
other investment advisers, including MFS' profitability with respect to the
Fund; and (11) other factors the Board of Trustees deemed relevant. Certain of
these factors are discussed in more detail below.

PORTFOLIO PERFORMANCE. The Board of Trustees determined that MFS has provided
high quality services with respect to the Fund. In particular, the Trustees
reviewed the performance for Class A shares of the Fund (as representative of
the Fund as a whole) against their Lipper peer group and noted that the Fund
was ranked by Lipper 8th out of 812 comparable funds, 22nd out of 495
comparable funds and 50th out of 301 comparable funds for the one, three and
five year periods, respectively, ending December 31, 1997. The Trustees also
noted that for the ten-year period ended December 31, 1997, the Fund was
ranked 41st by Lipper out of 177 comparable mutual funds ranked by Lipper.
During this same period, the Fund had an aggregate total return of 427.77% as
compared to a return of 358.00% for the Lipper Growth Fund Average.

The Board of Trustees also determined that the Fund's absolute performance and
performance relative to comparable mutual funds and indices would not have
been materially affected if the proposed increased advisory fees had been in
effect throughout 1995, 1996 and 1997.

The Fund's average annual total return performance in comparison with the
annualized total return performances of the Lipper Growth Fund Average and the
S&P 500 Index is set forth below:

- ----------
(1) Class B share performance includes the performance of the Fund's Class A
    shares for periods prior to the inception date of Class B shares on
    September 7, 1993. Sales charges, expenses and expense ratios, and
    therefore performance, for Class A and Class B shares differ. Class B
    share performance has been adjusted to take into account differences in
    sales charges but has not been adjusted to reflect differences in
    operating expenses (e.g., Rule 12b-1 fees), which generally are lower for
    Class A shares.
(2) Class C share performance includes the performance of the Fund's Class A
    shares for periods prior to the inception of offering of Class C shares on
    November 3, 1997. Sales charges, expenses and expense ratios, and
    therefore performance, for Class A and Class B shares differ. Class C
    share performance has been adjusted to take into account differences in
    sales charges but has not been adjusted to reflect differences in
    operating expenses (e.g., Rule 12b-1 fees), which generally are lower for
    Class A shares.
(3) Class I share performance includes the performance of the Fund's Class A
    shares for the periods prior to the inception of Class I shares on January
    2, 1997. Sales charges, expenses and expense ratios, and therefore
    performance for Class I and A shares differ. Class I share performance has
    been adjusted to take into account differences in sales charges but has
    not been adjusted to reflect differences in operating expenses (e.g., Rule
    12b-1 fees), which generally are lower for Class I shares.

The S&P 500 Index is unmanaged, assumes reinvestment of estimated dividends
and does not reflect fees and expenses. Investors may not invest directly in
an index. The Lipper Growth Fund Average and the Fund's performance assume
reinvestment of capital gains and dividends and do not reflect the deduction
of sale charges.

The Trustees also considered the nature, quality and extent of the investment
advisory services rendered by MFS to the Fund as well as the background of the
portfolio managers and other executive personnel of MFS. MFS provided insights
on the competition it faces in attracting top quality personnel and the
Trustees reviewed MFS' recent additions of portfolio managers, analysts and
others involved in research and quantitative analysis.

The Trustees reviewed the 66-year performance history of the Fund under MFS
and the fact that MFS and its predecessors have been the sole investment
adviser to the Fund since 1932. The Trustees gave substantial weight to that
history and the historical importance of continuity through the many market
cycles during this period.

CHANGES IN THE MUTUAL FUND INDUSTRY. The Board of Trustees considered the
effect of changes in the mutual fund industry since the Fund's last management
fee increase in 1976. Among these changes, the Trustees considered the
increasing globalization of the economy and its impact on the management of
the Fund. The Trustees also considered the increased competitiveness in the
mutual fund industry that has resulted from the growth in the total assets
under management and in the number of funds offered. They evaluated the impact
of multiple classes of shares and a need for enhanced marketing efforts by
MFS, the increased expense incurred by MFS and its affiliates (primarily the
Fund's distributor, MFD) in connection with such enhanced marketing efforts,
and their effectiveness. The Trustees reviewed these factors in assessing the
current competitive environment in the mutual fund industry. However, in
evaluating the fee increase proposal, the Trustees specifically excluded from
consideration MFS' marketing expenditures and their effect on MFS'
profitability.

ACTUAL AND PRO FORMA MANAGEMENT FEES AND EXPENSES. The Board of Trustees
considered the effect of the proposed management fee increase on the Fund's
fee rates and annual expense ratios (which include the management fee and all
other operating expenses incurred by the Fund). The table set forth below
under "Effect of an Increase in the Management Fee" provides comparative data
for the fiscal year ended November 30, 1997, assuming that the proposed fee
increase had been in effect throughout the year.

COSTS OF PROVIDING SERVICE AND PROFITABILITY. The Board of Trustees reviewed
information concerning profitability of MFS' investment advisory and other
activities and its financial condition based on results from 1995 through
1997. The information considered by the Trustees included operating profit
margin information for MFS' investment company business alone (i.e., excluding
results of its affiliates) and on a consolidated basis both before and after
MFS' net expenditures for marketing. The Trustees also reviewed profitability
data for 1995, 1996 and 1997 for MFS on a fund-by-fund basis. In addition,
such data were reviewed on a pro forma basis assuming that the proposed
management fee increase had been in effect throughout 1995, 1996 and 1997. In
assessing this information, the Trustees considered the fact that the size of
the Fund results in certain economies of scale to MFS. The Trustees recognized
that the growth of assets under management by the Adviser would have positive
effects on the Adviser's profitability even without the proposed fee increase;
however, the Trustees also considered the fact that the proposed fee increase
would enhance the Adviser's ability to attract and retain highly qualified
investment and administrative professionals in a competitive investment
management environment, and thus address the expectations of the Trustees
regarding the performance of the Fund that only such professionals can
satisfy.

Certain assumptions and methods of allocation utilized by the Adviser in
preparing fund-by-fund data were reviewed by the Trustees. While the Adviser
believes that the methods of allocation used were reasonable, there are
limitations inherent in allocating costs to multiple individual advisory
products served by an organization such as the Adviser's where each
of the advisory products draws on, and benefits from, the pooled research of
the organization.

COMPARISONS WITH OTHER FUNDS. The Board of Trustees considered the management
fees paid by other funds with similar investment objectives. In addition to
comparing the proposed management fee, the Board of Trustees also considered
the comparability of operating expense ratios with ratios of these other
investment companies. Notwithstanding that under the proposal the Fund's
management fee and, accordingly, its operating expense ratios, would increase,
the Trustees believe that the management fee and expense ratios would remain
well below industry averages. Based upon the data reported in Lipper
Directors' Analytical Data -- First Edition 1998, the Fund's Current Effective
Fee of 0.28% in 1997 was well below the 0.74% average management fee of the
706 investment companies with a similar investment objective, and on a pro
forma basis giving effect to the Proposed Fee, its ratio of management fee to
average net assets of 0.33% would also have been well below average. The
Fund's ratios of operating expenses to average net assets for Class A, Class
B, Class C and Class I shares were 0.84%, 1.49%, 1.49% and 0.49% respectively,
for the fiscal year ended November 30, 1997 (except with respect to Class A
shares which have been adjusted to reflect the increased distribution fee, see
"Expense Summary" below). After giving effect to the Proposed Fee, the ratios
of operating expenses to average daily net assets for Class A, Class B, Class
C and Class I shares would have been 0.89%, 1.54%, 1.54% and 0.54%,
respectively.

NON-ADVISORY SERVICES PROVIDED TO THE FUND. The Board of Trustees reviewed the
general nature of the non-investment advisory services performed by MFS, such
as administrative, transfer agency and distribution services and the fees
received by MFS for performing such services. In addition to reviewing such
services, the Trustees also considered the organizational structure employed
by MFS to provide those services.

EFFECT OF AN INCREASE IN THE MANAGEMENT FEE
The effect of the proposed increase in the Fund's management fee from the
Current Effective Fee of 0.28% to 0.33% per annum is illustrated below. For
the fiscal year ended November 30, 1997, this information illustrates the
amount the Fund paid to MFS under the Current Effective Fee, and the amount
the Fund would have paid to MFS had the Proposed Fee been in effect for the
entire period.

                     FISCAL YEAR ENDED NOVEMBER 30, 1997

                             % OF AVERAGE
MANAGEMENT FEE             DAILY NET ASSETS       AMOUNT OF FEE         % CHANGE
- --------------             ----------------       -------------         --------
Current Effective Fee           0.28%               $4,290,313
Proposed Fee                    0.33%               $5,079,371
Difference                      0.05%               $  789,058           18.4%

In addition to its provision of investment management services to the Fund,
MFS also acts as the Fund's administrator and provides administrative services
to the Fund for which it received an administrative services fee from the Fund
of $170,904 (equivalent on an annualized basis to 0.01% of the Fund's average
daily net assets) for the period March 1, 1997 (commencement of Administration
Agreement) to November 30, 1997. For fiscal year 1998, the Fund will pay MFS a
fee calculated as a percentage of the average daily net assets of the Fund at
maximum annual rate of 0.015% for these services. MFS Service Center, Inc.
("MFSC"), a wholly owned subsidiary of MFS, provides shareholder agency
services to the Fund for which it received a fee from the Fund of $2,002,304
(equivalent on an annualized basis to 0.13% of the Fund's average daily net
assets) for the fiscal year ended November 30, 1997. For fiscal year 1998, the
Fund will pay MFSC a fee calculated as a percentage of the average daily net
assets of the Fund at an effective annual rate of 0.1125% for these services.

Shown below is a chart of the expenses and fees the Fund incurred during its
fiscal year ended November 30, 1997 (except with respect to Class A shares
which have been adjusted to reflect an increase in the distribution fee, see
footnote (2) to the "Expense Summary" below), together with pro forma fees the
Fund would have paid had the proposed management fee of 0.33% per annum been
in effect the entire period.

(1) Purchases of $1 million or more and certain purchases by retirement plans are not subject to an initial sales charge;
    however, a contingent deferred sales charge ("CDSC") of 1% will be imposed on such purchases in the event of certain
    redemption transactions within 12 months following such purchases.
(2) The Fund has adopted a distribution plan for its shares in accordance with Rule 12b-1 under the 1940 Act (the "Distribution
    Plan"), which provides that it will pay distribution/service fees aggregating up to (but not necessarily all of) 0.35% per
    annum of the average daily net assets attributable to Class A shares. Assets attributable to Class A shares sold prior to
    March 1, 1991 are subject to a service fee of 0.15% per annum. The fee has been adjusted to include the 0.10% per annum
    distribution fee which, prior to April 1, 1998 had not been imposed. Distribution expenses paid under this plan, together
    with the initial sales charge, may cause long-term shareholders to pay more than the maximum sales charge that would have
    been permissible if imposed entirely as an initial sales charge.
(3) The Fund's Distribution Plan provides that it will pay distribution/ service fees aggregating up to 1.00% per annum of the
    average daily net assets attributable to Class B shares and Class C shares, respectively. Distribution expenses paid under
    the Distribution Plan with respect to Class B or Class C shares, together with any CDSC, may cause long-term shareholders to
    pay more than the maximum sales charge that would have been permissible if imposed entirely as an initial sales charge.
(4) 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."

FEES OF SIMILAR MFS FUNDS
MFS also acts as the investment adviser to several registered investment
companies having similar investment objectives to that of the Fund. MFS
sponsored the formation of a "clone" fund of the Fund earlier this year which
has a management fee of 0.75% of its average daily net assets. This "clone"
fund is not supervised by your Board of Trustees.

The table in Appendix A sets forth the name of each investment company managed
by MFS having similar investment objectives to the Fund that primarily invest
in equity securities, the annual rate of compensation (i.e., the fee MFS is
paid for its services as investment adviser to such funds) and the net assets
of such funds as of June 30, 1998.

FEES OF SIMILAR COMPETITIVE FUNDS
The Proposed Fee of 0.33% is significantly lower than the Lipper Growth Fund
Average of 0.74%. Moreover, the proforma total expense ratio for Class A would
have been in the fourth quartile of growth funds as tracked by Lipper, or more
than 75% of funds with similar investment objectives will still have total
expense ratios in their most recent fiscal year higher than that of the
Fund's.

INVESTMENT ADVISER
MFS is America's oldest mutual fund organization. MFS and its predecessor
organizations have a history of money management dating from 1924 and the
founding of the first mutual fund in the United States, Massachusetts
Investors Trust. Net assets under the management of the MFS organization were
approximately $87.7 billion on behalf of over 3.3 million investor accounts as
of June 30, 1998. MFS is a subsidiary of Sun Life Assurance Company of Canada
(U.S.) Financial Services Holdings, Inc. ("Sun Life of Canada (U.S.)") which
in turn is an indirect wholly owned subsidiary of Sun Life Assurance Company
of Canada ("Sun Life"). The Directors of MFS are Jeffrey L. Shames, John W.
Ballen, Arnold D. Scott, Kevin R. Parke, Thomas J. Cashman, Joseph Dello
Russo, William W. Scott, Jr., John D. McNeil and Donald A. Stewart. Mr. Shames
is the Chairman and Chief Executive Officer of MFS, Mr. Ballen is the
President and the Chief Investment Officer of MFS, Mr. Arnold Scott is the
Secretary and a Senior Executive Vice President of MFS, Mr. Parke is the Chief
Equity Officer, Director of Equity Research and an Executive Vice President of
MFS, Mr. Cashman is the President of MFS Institutional Advisors, Inc., MFS'
institutional investment management subsidiary, Mr. Dello Russo is the Chief
Financial Officer and an Executive Vice President of MFS and Mr. William Scott
is the President of MFS Fund Distributors Inc., MFS' mutual fund sales company
subsidiary. Messrs. McNeil and Stewart are the Chairman and the President,
respectively, of Sun Life. The address of Messrs. Shames, Ballen, Arnold
Scott, Parke, Cashman, Dello Russo and William Scott is 500 Boylston Street,
Boston, Massachusetts 02116. The address of Messrs. McNeil and Stewart is 150
King Street West, Toronto, Canada M5H 1J9. Sun Life, a mutual life insurance
company, is one of the largest international life insurance companies and has
been operating in the United States since 1895, establishing a headquarters
office here in 1973. The executive officers of MFS report to the Chairman of
Sun Life.

James R. Bordewick, Jr., Stephen E. Cavan, W. Thomas London, James O. Yost,
Ellen M. Moynihan and Mark E. Bradley, all of whom are officers of MFS, are
also officers of the Trust. [As of             , 1998, no officer or Trustee
of the Fund owned beneficially greater than 1% of the outstanding shares of
the Fund. As of such date, the officers and Trustees of the Fund in the
aggregate owned beneficially less than 1% of the outstanding shares of the
Fund.]

MFS also serves as investment adviser to over 150 other funds, including the
MFS Family of Funds (the "MFS Funds"), MFS Municipal Income Trust, MFS
Multimarket Income Trust, MFS Government Markets Income Trust, MFS
Intermediate Income Trust, MFS Charter Income Trust, MFS Special Value Trust,
MFS Institutional Trust, MFS Variable Insurance Trust, MFS/Sun Life Series
Trust, and seven variable accounts, each of which is a registered investment
company established by Sun Life of Canada (U.S.) in connection with the sales
of various fixed/variable annuity contracts. MFS and its wholly owned
subsidiary, MFS Institutional Advisors, Inc., also provide investment advice
to a large number of private clients.

In certain instances there may be securities which are suitable for the Fund's
portfolio as well as for portfolios of other clients of MFS. Some simultaneous
transactions are inevitable when several clients receive investment advice
from MFS, particularly when the same security is suitable for more than one
client. While in some cases this arrangement could have a detrimental effect
on the price or availability of the security as far as the Fund is concerned,
in other cases, however, it may produce increased investment opportunities for
the Fund.

Broker-dealers may be willing to furnish statistical, research and other
factual information or services to MFS for no consideration other than
brokerage or underwriting commissions. Securities may be bought or sold from
time to time through such broker-dealers on behalf of the Fund.

For the current fiscal year, the Board of Trustees (together with the Boards
of Trustees of the other MFS Funds) have directed MFS to allocate a total of
$54,160 of commission business from the Fund and the MFS Funds to the Pershing
Division of Donaldson, Lufkin and Jenrette as consideration for the annual
renewal of certain publications provided by Lipper (which provides information
useful to the Board of Trustees in reviewing the relationship between the Fund
and MFS).

The address of MFS and MFS Fund Distributors, Inc. ("MFD"), the Fund's
principal underwriter, is 500 Boylston Street, Boston, Massachusetts 02116.

DESCRIPTION OF THE NEW AGREEMENT
As noted above, the Current Agreement and the New Agreement are identical
except that the New Agreement provides for the payment by the Fund to MFS of a
higher management fee of 0.33% per annum, rather than the Current Effective
Fee of 0.28% per annum (the New Agreement also has a new commencement date and
termination date). Under the New Agreement, MFS provides portfolio management
services for the Fund, including investment research, advice and supervision
of the Fund's assets.

The Fund pays its expenses (other than those assumed by MFS or MFD),
including: investment advisory and administrative services; governmental fees;
interest charges; taxes; membership dues in the Investment Company Institute
allocable to the Fund; fees and expenses of independent auditors, of legal
counsel, and of any transfer agent, registrar or dividend disbursing agent of
the Fund; expenses of repurchasing and redeeming shares; expenses of
preparing, printing and mailing share certificates, shareholder reports,
notices, proxy statements and reports to governmental officers and
commissions; brokerage and other expenses connected with the execution,
recording and settlement of portfolio security transactions; insurance
premiums; fees and expenses of the Fund's custodian and transfer agent, for
all services to the Fund, including safekeeping of funds and securities and
maintaining required books and accounts; expenses of calculating the net asset
value of shares of the Fund; and expenses of shareholder meetings. Expenses
relating to the issuance, registration and qualification of shares of the Fund
and the preparation, printing and mailing of prospectuses for such purposes
are borne by the Fund except that its Distribution Agreement with MFD, the
Fund's principal underwriter, requires MFD to pay for prospectuses that are to
be used for sales purposes.

MFS pays the compensation of the Trust's officers who are affiliated with MFS
and any Trustee who is an officer of MFS. The Adviser also furnishes at its
own expense all necessary portfolio management services, including office
space, equipment, clerical personnel, investment advisory facilities, and all
executive and supervisory personnel necessary for managing the Fund's
investments and effecting transactions in its portfolio securities.

The New Agreement provides that in the absence of willful misfeasance, bad
faith or gross negligence, MFS shall not be liable for any act or omission in
the course of, or in connection with, the rendering of its services
thereunder.

The New Agreement, if approved, will remain in effect pursuant to its terms
until August 1, 2000 (for the Current Agreement, this date is August 1, 1999),
and thereafter for successive one-year periods if and so long as such
continuation is specifically approved at least annually by (a) the Board of
Trustees or (b) the affirmative vote of a majority of the outstanding voting
securities of the Fund, provided that in either event the continuation also is
approved by a majority of the Independent Trustees by a vote cast in person at
a meeting called for the purpose of voting on such approval. Under the 1940
Act, a "vote of a majority of the outstanding voting securities" of the Fund
means the affirmative vote of the lesser of (1) more than 50% of the
outstanding shares of the Fund or (2) 67% or more of the shares present at a
shareholders' meeting if more than 50% of the outstanding shares are
represented at the meeting in person or by proxy (a "1940 Act Majority Vote").
The New Agreement is terminable, without penalty, by the Board of Trustees, by
a 1940 Act Majority Vote of the Fund's shareholders or by MFS, in each case on
not more than sixty nor less than thirty days' written notice to the other
party and to the Fund. The New Agreement terminates automatically in the event
of its assignment (as defined in the 1940 Act).

The description of the New Agreement is qualified in its entirety by reference
to the New Agreement which is attached as Appendix B to this proxy statement.

REQUIRED VOTE
Approval of the New Agreement requires a 1940 Act Majority Vote of the Fund's
shareholders (as defined above).

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR
APPROVAL OF THE NEW AGREEMENT.

ITEM 2.  TO APPROVE OR DISAPPROVE THE ELIMINATION OF CERTAIN FUNDAMENTAL
         INVESTMENT POLICIES
As described in the following proposals, the Trustees are recommending that
shareholders approve the elimination of certain investment restrictions
currently observed by the Fund. The purpose of these proposed changes is to
increase the Fund's investment flexibility and reduce administrative and
compliance burdens by eliminating certain restrictive policies which were
required at one time by various state securities authorities but which are no
longer required under current regulations.

BACKGROUND
The 1940 Act requires a registered investment company like the Fund to have
certain specific investment policies which can be changed only by a
shareholder vote. Investment companies may also elect to designate other
policies which may be changed only by a shareholder vote. Both types of
policies are often referred to as "fundamental" policies. (In this Proxy
Statement, the word "restriction" is sometimes used to describe a policy.)
Some fundamental policies have been adopted in the past by the Fund to reflect
certain regulatory, business or industry conditions which are no longer in
effect. In particular, the National Securities Markets Improvement Act of 1996
permits investment companies to eliminate investment restrictions formerly
imposed by state securities ("Blue Sky") regulations. Accordingly, MFS
undertook a review of the Fund's fundamental policies to determine whether any
policies which are not required by the 1940 Act could be eliminated.

The proposed elimination of certain of the Fund's fundamental policies are
discussed in detail below. Please refer to Appendix C for a full description
of these policies. By eliminating policies which are no longer required the
Trustees believe that MFS' ability to manage the Fund's portfolio in a
changing regulatory or investment environment will be enhanced and the process
of monitoring the compliance with investment restrictions will be simplified.
Accordingly, investment management opportunities will be increased. The
references to the Fund's investment restrictions correspond to the paragraphs
in Appendix C.

ELIMINATION OF CERTAIN RESTRICTIONS
The Trustees propose to delete Restrictions (9), (10), (11), (12), (13) and
(14) (see "Investment Objective, Policies and Restrictions" in the Fund's
Statement of Additional Information), which were formerly required by various
state Blue Sky laws, because such restrictions are not required to be
fundamental policies under the 1940 Act and/or the practices referred to
therein are otherwise governed by the 1940 Act.

A. RESTRICTION CONCERNING INVESTMENT IN OTHER INVESTMENT COMPANIES.
Restriction (9) concerns investment in other investment companies and
prohibits the Fund from investing in securities of other investment companies.
This restriction was formerly required by certain states' Blue Sky laws.
Investment in other investment companies is otherwise regulated by the 1940
Act, therefore the Trustees believe this restriction is no longer necessary.

B. RESTRICTION CONCERNING TRANSACTIONS WITH AFFILIATES.
Restriction (10) prohibits the Fund from investing in securities of issuers in
which management of the Fund or MFS owns a certain percentage of securities.
This restriction was formerly required by certain states' Blue Sky laws. MFS
recommended the elimination of this restriction in order to provide the Fund
with the maximum amount of flexibility.

If this restriction is eliminated the Fund would be able to invest in the
securities of any issuer without regard to ownership in such issuer by
management of the Fund or MFS, except to the extent prohibited by the Fund's
investment objective and policies and the 1940 Act. Such transactions are
circumscribed by the 1940 Act's provisions on affiliated transactions and MFS
maintains a code of ethics to monitor transactions affecting the Fund;
therefore, the Trustees believe this restriction is no longer necessary.

C. RESTRICTION CONCERNING PURCHASING SECURITIES ON MARGIN.
Restriction (11) concerns purchasing securities on margin and was required in
the past by certain states' Blue Sky laws. MFS recommended elimination of this
restriction to provide the Fund with maximum flexibility. The Fund's potential
use of margin transactions beyond transactions in futures and options and for
the clearance of purchases and sales of securities, including the use of
margin in ordinary securities transactions, is generally limited by the
current position taken by the staff of the Securities and Exchange Commission
(the "SEC"), that margin transactions with respect to securities are
prohibited under the 1940 Act because they create senior securities. "Margin
transactions" involve the purchase of securities with money borrowed from a
broker, with cash or eligible securities being used as collateral against the
loan. The Fund's ability to engage in margin transactions is also limited by
its borrowing policies, which permit the Fund to borrow money in limited
circumstances and only from banks. The Trustees believe that there are
adequate safeguards in place and that the Fund will benefit from the increased
flexibility provided by the elimination of this restriction.

D. RESTRICTION CONCERNING SHORT SALES.
Restriction (12) concerns short sales and prohibits the Fund from engaging in
such transactions unless they are "against the box." This restriction was
formerly required by certain states' Blue Sky laws. MFS recommended the
elimination of this restriction in order to provide the Fund with the maximum
amount of flexibility.

In a typical short sale the Fund borrows securities from a broker that it
anticipates will decline in value in order to sell to a third party. The Fund
becomes obligated to return securities of the same issue and quantity at some
future date, and it realizes a profit or loss depending upon whether the
market price of the security decreases or increases between the date of the
short sale and the date on which the Fund must replace the borrowed security.
Since the value of a particular security can increase without limit, the Fund
could potentially realize losses with respect to short sales that are not
"against the box" (short sales where the Fund owns or has the right to acquire
at no added cost securities identical to those sold short), that could be
significantly greater than the value of the securities at the time they are
sold short.

E. RESTRICTION CONCERNING CERTAIN TYPES OF OPTIONS.
Restriction (13) concerns purchasing certain types of options. Such
restrictions were only formerly required by certain states' Blue Sky laws. MFS
recommended the elimination of this restriction in order to provide the Fund
with the maximum amount of flexibility.

If the proposal is approved, the Fund would no longer be prohibited from
engaging in a variety of options transactions for hedging purposes and to
increase investment return. MFS believes that this enhanced flexibility could
assist the Fund in achieving its investment objective under certain market
conditions. A call option gives the holder the right to purchase, and
obligates the writer to sell, an asset, such as a security, a currency or a
unit of an index, at the exercise price prior to or on the expiration date. A
put option gives the holder the right to sell, and obligates the writer to
buy, an asset at the exercise price prior to or on the expiration date. In
order for a put option purchased by the Fund to be profitable, the market
price of the underlying asset must decline sufficiently below the exercise
price to cover the premium and transaction costs paid by the Fund. In order
for a call option purchased by the Fund to be profitable, the market price of
the underlying asset must rise sufficiently above the exercise price to cover
the premium and transaction costs paid by the Fund. If an option expires
unexercised, the Fund will receive nothing for its premium payment.

When the Fund writes a call option, it gives up the opportunity to profit from
any increase in the price of an asset above the exercise price of the option;
when it writes a put option, the Fund takes the risk that it will be required
to purchase an asset from the option holder at a price above the current
market price of that asset. The Fund receives a premium for writing a call or
a put option (representing the cost of the option), which increases the return
if the option expires unexercised or is closed out at a net profit.

The successful use of options depends on the ability of MFS to forecast
correctly interest rate and market movements. The effective use of options
also depends on the Fund's ability to terminate option positions at times when
MFS deems it desirable to do so. There is no assurance that the Fund will be
able to effect closing transactions at any particular time or at an acceptable
price. Disruptions such as trading interruptions or restrictions on option
exercise in the markets for securities and other assets underlying options
purchased or sold by the Fund could result in losses on an option, including
the entire investment by the Fund in the option.

F. RESTRICTION CONCERNING INVESTMENTS IN UNSEASONED ISSUERS.
Restriction (14) concerns investments of more than 5% of the Fund's assets in
"unseasoned issuers" (e.g., companies which have been in operation for less
than three years). This restriction was formerly required by certain states'
Blue Sky laws. The Adviser recommended the elimination of this restriction in
order to provide the Fund with the maximum amount of flexibility.

Unseasoned issuers may have relatively small equity capitalizations (e.g.,
under $1 billion). Although these companies may provide greater opportunities
for increased investment return, they also involve greater risk. These
companies often have limited product lines, markets or financial resources.
The securities of these companies may trade less frequently and in limited
volume, and only in the over-the-counter market or on a regional securities
exchange. As a result, these securities may fluctuate in value more than those
of larger, more established companies. The Trustees believe that elimination
of the policy will increase the flexibility of MFS in managing the Fund's
assets by permitting investments by the Fund in unseasoned issuers that
otherwise meet the investment objective and policies of the Fund. While
securities of these issuers may be subject to greater risk, the Trustees
believe that the increasing prevalence of unseasoned issuers, the investment
opportunities offered by such issuers, and the fact that any such investments
will be made in accordance with the investment objective and policies of the
Fund, warrants the elimination of the current restriction.

REQUIRED VOTE
Approval of each of these proposals requires a 1940 Act Majority Vote of the
Fund's shareholders (as defined above).

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
APPROVAL OF PROPOSALS 2A-F.

The adoption of any of these proposals is not contingent on the adoption of
any other proposal. If the proposals are adopted by the shareholders of the
Fund, they will take effect immediately. If any proposal is not approved by
the shareholders, the Fund's present investment restriction relating to that
proposal will remain in effect.

ITEM 3.  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 the Independent Trustees of the
Fund, of Deloitte & Touche LLP pursuant to Section 32(a) of the 1940 Act as
independent public accountants to certify every financial statement of the
Fund required by any law or regulation to be certified by independent public
accountants and filed with the SEC in respect of all or any part of the fiscal
year ending November 30, 1998. Deloitte & Touche LLP has no direct or material
indirect interest in the Fund. A representative of Deloitte & Touche LLP is
expected to be present at the Meeting and will have an opportunity to make a
statement if he desires to do so. Such representative is also expected to be
available to respond to appropriate questions.

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
APPROVAL OF THIS ITEM.

MANNER OF VOTING PROXIES
If an enclosed proxy is properly executed and returned in time to be voted at
the Special Meeting, (either by returning the paper proxy card or by
submitting your proxy electronically via the Internet or by telephone) the
shares represented thereby will be voted in accordance with the instructions
marked thereon. Unless instructions to the contrary are marked thereon, a
proxy will be voted "for" the matters listed in the accompanying Notice of
Special Meeting of Shareholders and "for" any other matters deemed
appropriate. If a proxy is properly executed and returned accompanied by
instructions to withhold authority to vote (sometimes called a broker "non-
vote" (that is, a proxy from a broker or nominee indicating that this person
has not received instructions from the beneficial owner or other person
entitled to vote shares on a particular matter with respect to which the
broker or nominee does not have discretionary power)), or is marked with an
abstention (collectively, "abstentions"), the shares represented thereby will
be considered to be present at the Special Meeting for purposes of determining
the existence of a quorum for the transaction of business. Abstentions will
not constitute a vote "for" or "against" a matter and will be disregarded in
determining the "votes cast" on an issue. Therefore, abstentions will have the
same effect as a vote "against" proposal 1 and proposals 2A-F, and will have
no effect on proposal 3.

Proxy solicitations will be made primarily by mail, but proxy solicitations
also may be made by telephone, telegraph, electronic means or personal
interviews conducted by officers of the Fund, MFS, MFD, and/or MFSC, the
transfer agent for the Fund. In addition, Shareholder Communications
Corporation has been retained to assist in the solicitation of proxies, at an
estimated cost of $[      ] (depending on the extent of services provided). The
costs of the proxy solicitation and expenses incurred in connection with the
preparation, printing and mailing of this proxy statement and its enclosures
will be borne by MFS and not by the Fund. MFS will reimburse banks, brokers
and other persons holding the Fund's shares registered in their names or in
the names of their nominees, for their expenses incurred in sending proxy
material to and obtaining proxies from the beneficial owners of such shares.

The management knows of no other matters to be brought before the Special
Meeting. If, however, any other matters properly come before the Special
Meeting and any adjournments thereof, it is the management'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.

INTERNET AND TELEPHONE VOTING -- For shares that are registered in your name,
as well as for shares that you beneficially own and hold in "street name"
through a broker, you have the opportunity to vote via the Internet or by
telephone by utilizing a program provided through ADP Investor Communication
Services ("ADP"). The giving of such a proxy will not affect your right to
vote in person should you decide to attend the Special Meeting.

To vote via the Internet or telephone you will need the 12-digit "control"
number that appears on your proxy card. To vote via the Internet, please
access MFS or ADP on the World Wide Web at www.mfs.com or www.proxyvote.com,
respectively. To vote by telephone, please call the toll-free phone number
listed on your proxy card.

The Internet voting procedures are designed to authenticate shareholder
identities, to allow shareholders to give their voting instructions and to
confirm that shareholders' instructions have been recorded properly.
Shareholders voting via the Internet should understand that there may be costs
associated with electronic access, such as usage charges from Internet access
providers and telephone companies, that must be borne by the shareholders.

SUBMISSION OF CERTAIN PROPOSALS
The Fund is a Massachusetts business trust, and as such is not required to
hold annual meetings of shareholders. However, meetings of shareholders may be
held from time to time to consider such matters as the approval of investment
advisory agreements or changes in certain investment restrictions. Proposals
of shareholders which are intended to be presented at future shareholder's
meetings must be received by the Fund a reasonable time prior to the Fund's
solicitation of proxies relating to such future meeting.

ADDITIONAL INFORMATION
[As of the Record Date, Merrill Lynch Pierce Fenner & Smith, Inc., 4800 Deer
Lake Drive, Jacksonville, Florida, for the sole benefit of its customers, held
[      ] shares of the Fund ([    ]% of the outstanding shares) as holder of
record, but not beneficially and the MFS Defined Contribution Plan, 500
Boylston Street, Boston, MA, owned [      ] shares of the Fund ([   ]% of the
outstanding shares).]

The information contained in this proxy statement relating to MFS has been
furnished by MFS.

In the event that sufficient votes in favor of the proposals set forth in the
Notice of Special Meeting are not received by October 15, 1998, the persons
named as appointed proxies on the enclosed proxy card may propose one or more
adjournments of the Special Meeting to permit further solicitation of proxies.
Any such adjournment will require the affirmative vote of the holders of a
majority of the shares present in person or by proxy at the session of the
meeting to be adjourned. The persons named as appointed proxies on the
enclosed proxy card will vote in favor of any such adjournment those proxies
required to be voted in favor of the proposal for which further solicitation
of proxies is to be made. They will vote against any such adjournment those
proxies required to be voted against such proposal. The costs of any such
additional solicitation and of any adjourned session will by borne by MFS.

              IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY

                        INVESTMENT ADVISORY AGREEMENT

THIS AGREEMENT, made this 1st day of November, 1998 by and between
MASSACHUSETTS INVESTORS GROWTH STOCK FUND, a Massachusetts business trust (the
"Fund") and MASSACHUSETTS FINANCIAL SERVICES COMPANY, a Delaware corporation
(the "Adviser").

                                 WITNESSETH:

WHEREAS, the Fund is engaged in business as an open-end investment company
registered under the Investment Company Act of 1940;

WHEREAS, the Adviser is willing to provide business management services to the
Fund on the terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of the mutual covenants and agreements of the
parties hereto as herein set forth, the parties covenant and agree as follows:

ARTICLE 1:  Duties of the Adviser.  The Adviser shall provide the Fund with
such investment advice and supervision as the latter may from time to time
consider necessary for the proper management of its funds. The Adviser shall
act as Adviser to the Fund and as such shall furnish continuously an
investment program and shall determine from time to time what securities shall
be purchased, sold or exchanged and what portion of the assets of the Fund
shall be held uninvested, subject always to the restrictions of the
Declaration of Trust, dated March 4, 1985, and By-Laws, each as amended from
time to time (respectively, the "Declaration" and the "By-Laws"), and to the
provisions of the Investment Company Act of 1940. The Adviser shall also make
recommendations as to the manner in which voting rights, rights to consent to
corporate action and any other rights pertaining to the Funds' portfolio
securities shall be exercised. Should the Trustees at any time, however, make
any definite determination as to the investment policy and notify the Adviser
thereof in writing, the Adviser shall be bound by such determination for the
period, if any, specified in such notice or until similarly notified that such
determination has been revoked. The Adviser shall take, on behalf of the Fund,
all actions which it deems necessary to implement the investment policies
determined as provided above, and in particular to place all orders for the
purchase or sale of portfolio securities for the Funds' account with brokers
or dealers selected by it, and to that end the Adviser is authorized as the
agent of the Fund to give instructions to the Custodian of the Fund as to
deliveries of securities and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of
such orders, the Adviser is directed to seek for the Fund execution at the
most favorable price by responsible brokerage firms at reasonably competitive
commission rates. In fulfilling this requirement the Adviser shall not be
deemed to have acted unlawfully or to have breached any duty, created by this
Agreement or otherwise, solely by reason of its having caused the Fund to pay
a broker or dealer an amount of commission for effecting a securities
transaction in excess of the amount of commission another broker or dealer
would have charged for effecting that transaction, if the Adviser determined
in good faith that such amount of commission was reasonable in relation to the
value of the brokerage and research services provided by such broker or
dealer, viewed in terms of either that particular transaction or the Adviser's
overall responsibilities with respect to the Fund and to other clients of the
Adviser as to which the Adviser exercises investment discretion.

ARTICLE 2:  Allocation of Charges and Expenses.  The Adviser shall furnish at
its own expense all necessary administrative services, office space, equipment
and clerical personnel, and investment advisory facilities and executive and
supervisory personnel for managing the investments, effecting the portfolio
transactions and in general administering the affairs of the Fund. The Adviser
shall arrange, if desired by the Fund, for officers and employees of the
Adviser to serve as Trustees, officers or agents of the Fund if duly elected
or appointed to such positions and subject to their individual consent and to
any limitations imposed by law. It is understood that the Fund will pay all of
its own expenses including, without limitation, compensation of Trustees not
affiliated with the Adviser, governmental fees, interest charges, taxes,
membership dues in the Investment Company Institute allocable to the Fund,
fees and expenses of independent auditors, of legal counsel and of any
transfer agent, registrar or dividend disbursing agent of the Fund, expenses
of repurchasing and redeeming shares, expenses of preparing, printing and
mailing share certificates, prospectuses, shareholders' reports, notices,
proxy statements and reports to governmental officers and commissions,
brokerage and other expenses connected with the execution of portfolio
security transactions, insurance premiums, fees and expenses of the custodian
for all services to the Fund, including safekeeping of funds and securities,
keeping of books and accounts and calculation of the net asset value of shares
of the Fund, expenses of shareholders' meetings, and expenses relating to the
issuance, registration and qualification of shares of the Fund.

ARTICLE 3:  Compensation of the Adviser.  For the services to be rendered and
the facilities to be furnished as provided in Articles 1 and 2 above, the Fund
shall pay to the Adviser an investment advisory fee computed and paid monthly
at a rate equal to 0.33% of the Fund's average daily net assets on an
annualized basis. If the Adviser shall serve for less than the whole of any
period specified in this Article 3, the compensation to the Adviser shall be
prorated.

ARTICLE 4:  Brokerage Offset Account.  The Adviser hereby assumes
responsibility of Massachusetts Financial Services, Inc. ("MFS") for carrying
out the terms of Article 4 of the Investment Advisory Agreement dated December
10, 1971, between Massachusetts Investors Growth Stock Fund, Inc. (the
"Predecessor Fund") and MFS to the extent set forth below. Pursuant thereto,
MFS agreed that prior to or promptly following December 10, 1971, it would
apply, through a subsidiary or affiliate (the "affiliate"), for membership on
the Philadelphia Stock Exchange and/or for the status of approved non-member
on the Pacific Coast Stock Exchange. Said agreement shall continue in full
force and effect with respect to the Adviser and the Fund, as successor to the
Predecessor Fund.

    (a) In the event that any such application is granted, the Adviser, to the
        extent permitted by the rules of such exchange or exchanges, shall
        credit against the management fees of the Fund a portion of the "net
        profits" of the affiliate computed in the manner described below. Such
        "net profits" of the affiliate shall be offset in the appropriate
        amount against the management fee owed to the Adviser by the Fund at
        any time or from time to time in the three months immediately
        succeeding the end of the affiliate's fiscal year.

    (b) During each fiscal year of the affiliate, gross revenues of the
        affiliate from brokerage transactions** for the portfolios of the
        Trust and the Fund, or attributable thereto, will be credited to an
        Offset Account for the Trust and the Fund. The Offset Account will be
        charged with all of the direct expenses of each such transaction,
        including applicable clearing fees, transfer taxes, exchange fees, or
        other fees and a share of the expenses of the affiliate's operations
        prorated on the basis of the affiliate's gross brokerage revenues from
        brokerage transactions for the portfolios of the Trust and the Fund,
        compared to the affiliate's gross revenues from all sources. The
        expenses to be so prorated will include rent, depreciation of
        depreciable capital assets over their useful lives, interest
        attributable to the affiliate's operations, salaries for personnel to
        the extent they are engaged in the operations of the affiliate
        including its recordkeeping and accounting and other direct expenses
        and costs incurred in connection with the affiliate's operations. In
        addition, in lieu of the affiliate's indirect expenses, such as
        general overhead, executive supervision and general administration,
        there will be charged to the Offset Account an amount equal to twenty
        per cent of the gross revenues credited to the Offset Account. Other
        adjustments customary to a brokerage operation may be made to the
        Offset Account. After deducting expenses as set forth above from the
        gross commissions attributed to the Offset Account, there shall be
        deducted an amount attributed to State and Federal income taxes, the
        sum to be deducted for this purpose to be computed as if the Offset
        Account were a Massachusetts business corporation required to file
        separate Massachusetts and Federal income tax returns. The balance in
        the account after the above deductions will be considered "net
        profits" of the Offset Account.

- ----------
**As used in this Article, the term "brokerage transaction" shall mean any
  purchase or sale of securities in connection with which a commission is paid
  to a broker-dealer acting as broker or agent and the terms "brokerage
  commissions" and "brokerage revenues" shall mean those commissions and
  revenues which are attributable to brokerage transactions.

    (c) The net profits of the Offset Account shall be divided between the
        Trust and the Fund in proportion to the total dollar amount of all
        portfolio transactions, other than transactions in government
        securities and short-term corporate notes, of the Trust and the Fund
        during the period for which the net profits are computed.

    (d) With respect to each fiscal year of the affiliate, all net profits of
        the Offset Account shall be offset against the management fees of the
        Trust and the Fund to the extent earned.

    (e) Following the end of the affiliate's fiscal year, the Adviser and the
        affiliate shall furnish to the Fund a financial statement for the
        Offset Account and an opinion with respect thereto by an independent
        public accountant.

    (f) The Adviser is hereby expressly authorized, subject to the primary
        requirement of obtaining for the Fund the most favorable execution and
        price, to direct to itself or its affiliate such brokerage
        transactions of the Fund as it shall in its sole discretion determine
        appropriate, except that in no event shall the Adviser or its
        affiliate execute portfolio transactions with the Fund on a principal
        basis, except as permitted by the Investment Company Act of 1940 and
        the Rules, Regulations or orders thereunder.

ARTICLE 5:  Shareholder Approval.  The Adviser agrees that, while this
Agreement is in effect, it will not permit (i) attribution of any value to
this Agreement in computing the value of the Adviser's stock, or (ii) sales of
stock by the Adviser or its shareholders at prices in excess of value
(excluding attribution of any value to the Agreement), without, in either
case, first obtaining the favorable vote of a majority of the outstanding
voting securities of the Fund.

The Fund agrees that upon notification by the Adviser that it intends to
engage in attribution of value or sales as described above, which would
require approval by shareholders of the Fund under this Agreement, it will
submit the question of approval or disapproval of such action to its
shareholders as promptly as practicable after receipt of such notice.

ARTICLE 6:  Covenants of the Adviser.  The Adviser agrees that it will not
deal with itself, or with the Trustees of the Fund or the Underwriter as
principals in making purchases or sales of securities or other property for
the account of the Fund, except as permitted by the Investment Company Act of
1940 and the Rules, Regulations or orders thereunder, will not take a long or
short position in the shares of the Fund except as provided by the
Declaration, and will comply with all other provisions of the Declaration and
By-Laws relative to the Adviser and its officers and directors.

ARTICLE 7:  Limitation of Liability of the Adviser.  The Adviser shall not be
liable for any error of judgment or mistake of law or for any loss arising out
of any investment or for any act or omission in the execution and management
of the Fund, except for willful misfeasance, bad faith or gross negligence in
the performance of its duties, or by reason of reckless disregard of its
obligations and duties hereunder. As used in this Article 7, the term
"Adviser" shall include directors, officers and employees of the Adviser as
well as the corporation itself.

ARTICLE 8:  Activities of the Adviser.  The services of the Adviser to the
Fund are not to be deemed to be exclusive, the Adviser being free to render
services to others. It is understood that Trustees, officers, and shareholders
of the Fund may be or become interested in the Adviser, as directors,
officers, employees, or otherwise and that directors, officers and employees
of the Adviser may be or become similarly interested in the Fund, and that the
Adviser may be or become interested in the Fund as shareholder or otherwise.

ARTICLE 9:  Duration, Termination and Amendment of this Agreement.  This
Agreement shall become effective on the date of its execution and shall govern
the relationship between the parties hereto thereafter, and shall remain in
force until August 1, 2000 on which date it will terminate unless its
continuance after August 1, 2000 is specifically approved at least annually
(i) by the vote of a majority of the Trustees of the Fund who are not
interested persons of the Fund or of the Adviser at a meeting specifically
called for the purpose of voting on such approval, and (ii) by the Trustees of
the Fund, or by vote of a majority of the outstanding voting securities of the
Fund. The aforesaid requirement that continuance of this Agreement be
"specifically approved at least annually" shall be construed in a manner
consistent with the Investment Company Act of 1940 and the Rules and
Regulations thereunder.

This Agreement may be terminated at any time without the payment of any
penalty by the Trustees or by vote of a majority of the outstanding voting
securities of the Fund, or by the Adviser, on not more than sixty days' nor
less than thirty days' written notice to the other party. This Agreement shall
automatically terminate in the event of its assignment.

This Agreement may be amended only if such amendment is approved by vote of a
majority of the outstanding voting securities of the Fund.

The terms "vote of a majority of the outstanding voting securities",
"assignment", "affiliated person", and "interested person", when used in this
Agreement, shall have the respective meanings specified in the Investment
Company Act of 1940 and the Rules and Regulations thereunder, subject,
however, to such exemptions as may be granted by the Securities and Exchange
Commission under said Act, and the term "brokerage and research services"
shall have the meaning given in the Securities Exchange Act of 1934 and the
Rules and Regulations thereunder.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed and delivered in their names and on their behalf by the undersigned
officers thereunto duly authorized, and their respective seals to be hereto
affixed, all as of the day and year first above written. The undersigned
Trustee of the Fund has executed this Agreement not individually, but as
Trustee under the Declaration and the obligations of this Agreement are not
binding upon any of the Trustees or shareholders of the Fund, individually,
but bind only the trust estate.

        FUNDAMENTAL INVESTMENT RESTRICTIONS PROPOSED TO BE ELIMINATED

As set forth in the Fund's current Statement of Additional Information, the
Fund may not:

 (9) Purchase securities issued by any other registered investment company
     except by purchase in the open market where no commission or profit to a
     sponsor or dealer results from such purchase other than the customary
     broker's commission, or except when such purchase, though not made in the
     open market, is part of a plan of merger or consolidation; provided,
     however, that the Fund shall not purchase the securities of any
     registered investment company if such purchase at the time thereof would
     cause more than 10% of the Fund's total assets, taken at market value, to
     be invested in the securities of such issuer; and provided, further, that
     the Fund shall not purchase securities issued by any open-end investment
     company.

(10) Purchase or retain any securities of an issuer any of whose officers,
     directors, trustees or security holders is an officer or Trustee of the
     Fund, or is a member, officer or Director of the Adviser, if after the
     purchase of the securities of such issuer by the Fund one or more of such
     persons owns beneficially more than  1/2 of 1% of the shares or
     securities, or both, all taken at market value, of such issuer, and such
     persons owning more than  1/2 of 1% of such shares or securities together
     own beneficially more than 5% of such shares or securities, or both, all
     taken at market value.

(11) Purchase any securities or evidences of interest therein on margin,
     except that the Fund may obtain such short-term credit as may be
     necessary for the clearance of purchases and sales of securities and
     except that the Fund may make margin deposits in connection with options,
     Futures Contracts, Options on Futures Contracts and Forward Contracts.

(12) Sell any security which the Fund does not own unless by virtue of its
     ownership of other securities the Fund has at the time of sale a right to
     obtain securities without payment of further consideration equivalent in
     kind and amount to the securities sold and provided that if such right is
     conditional the sale is made upon the same conditions.

(13) Purchase or sell any put or call option or any combination thereof;
     provided, that this shall not prevent the purchase, ownership, holding or
     sale of warrants where the grantor of the warrants is the issuer of the
     underlying securities or the writing, purchasing and selling of puts,
     calls or combinations thereof with respect to securities, indexes of
     securities, foreign currencies and Futures Contracts.

(14) Invest more than 5% of its assets in companies which, including
     predecessors, have a record of less than three years" continuous
     operation.
