in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                         INVESTMENT ADVISORY AGREEMENT


THIS AGREEMENT,  made this 19th day of July,  1985 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determination  has been revoked.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
<PAGE>
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 for
the  facilities to be furnished as provided in Articles 1 and 2 above,  the Fund
shall pay to the  Adviser a fee  computed  and paid  monthly at the annual  rate
equivalent  to 1/2 of 1% of the first $200  million of average  daily net assets
for the  Fund's  current  fiscal  year,  4/10 of 1% of the next $300  million of
average  daily net assets for the Fund's  current  fiscal year and 2/10 of 1% of
the  average  daily net assets for the Fund's  current  fiscal year in excess of
$500 million,  provided that such  computation  shall  commence on the effective
date of this Agreement and shall be based on the average daily net assets of the
Fund, on and after such date.
<PAGE>
The  annual  fee shall be  reduced  by 24%* of the fair value of the use for one
year of the office furniture,  furnishings and equipment  beneficially  owned by
the Fund and Massachusetts Investors Trust (the "Trust") and used by the Adviser
in the conduct of its affairs.  Such reduction shall be computed  monthly on the
basis  of 1/12 of 24% of such  fair  value  and be  deducted  from  the  monthly
payments of the fee provided for in the proceeding paragraph.

The fair value of one  year's  use of said  office  furniture,  furnishings  and
equipment has been  appraised as of May 9, 1969 at $39,208 by Dunton  Corp.,  an
independent supplier of office equipment on the basis of independent  appraisals
by others of its fair market  value,  depreciated,  in the case of  depreciating
property according to Internal Revenue Service guidelines and including a factor
for current  return on invested  capital.  The Adviser  shall  purchase  any new
equipment needed,  and the Fund shall receive 24% of the proceeds of any turn-in
or salvage  value of the obsolete or unneeded  furniture or  equipment.  The use
values so determined  shall be adjusted  annually and reviewed and approved by a
majority  of the  Trustees  of the Fund not  affiliated  with the  Adviser.  The
Adviser shall maintain and insure the property.

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 grated, 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
________________________________
* This percentage represents the aveerage of the annual percentages of office
  expenses shares with Massachusetts Investors Trust over the ten years ended
  December 31, 1968 and borne by the Fund.
* 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.
<PAGE>
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.

(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
<PAGE>
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, 1986 on which date it will  terminate  unless  its  continuance
after August 1, 1986 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.
<PAGE>

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.

                               CUSTODIAN CONTRACT

         This Contract  between  Massachusetts  Investors  Growth Stock Fund, a
business  trust  organized and existing  under the laws of the  Commonwealth  of
Massachusetts,  having its principal  place of business at 200 Berkeley  Street,
Boston, Massachusetts, hereinafter called the "Trust", and State Street Bank and
Trust Company,  a  Massachusetts  trust company,  having its principal  place of
business at 225  Franklin  Street,  Boston,  Massachusetts,  02110,  hereinafter
called the "Custodian".

         WITNESSETH,   that  in   consideration  of  the  mutual  covenants  and
agreements hereinafter contained, the parties hereto agree as follows:

1.       Employment of Custodian and Property to be Held by It. The Trust hereby
employs the Custodian as the custodian of its assets  pursuant to the provisions
of the Declaration of Trust.  The Trust,  agrees to deliver to the Custodian all
securities  and cash  owned by it,  and all  payments  of  income,  payments  of
principal or capital distributions received by it with respect to all securities
owned by the Trust from time to time, and the cash consideration  received by it
for such new or treasury shares of beneficial  interest  ("Shares") of the Trust
as may be  issued  or sold  from  time  to  time.  The  Custodian  shall  not be
responsible  for any property of the Trust held or received by the Trust and not
delivered to the Custodian.

         Upon  receipt of "Proper  Instructions"  (within the meaning of Section
2.17), the Custodian shall from time to time employ one or more  sub-custodians,
but only in accordance  with an applicable  vote by the Board of Trustees of the
Trust, and provided that the Custodian shall have no more or less responsibility
or  liability  to the  Trust on  account  of any  actions  or  omissions  of any
subcustodian so employed than any such subcustodian has to the Custodian.

2.       Duties of the Custodian with Respect to Property of the Trust Held By
the Custodian.

2.1.     Holding Securities. The Custodian shall hold and physically segregate
for the account of the Trust all non-cash  property,  including  all  securities
owned by the Trust,  other than  securities  which are  maintained  pursuant  to
Section 2.12 in a clearing agency which acts

Department  of the  Treasury,  collectively  referred to herein as a "Securities
System".

2.2.     Delivery of Securities. The Custodian shall release and deliver
securities  owned by the Trust held by the  Custodian or in a Securities  System
account of the Custodian only upon receipt of Proper Instructions,  which may be

following cases:

         1)  Upon sale of such securities for the account of the Trust and
receipt of payment therefor;

         2)  Upon the receipt of payment in connection with any repurchase

         5)  To the issuer thereof or its agent when such securities are called,

the cash or other consideration is to be delivered to the Custodian;

         6)  To the issuer thereof, or its agent, for transfer into the name of
the Trust or into the name of any nominee or nominees of the  Custodian  or into
the name or nominee name of any agent appointed pursuant to Section 2.11 or into
the name or nominee name of any subcustodian appointed pursuant to Article l; or
for exchange for a different  number of bonds,  certificates  or other  evidence
representing  the same aggregate face amount or number of units;  provided that,
in any such case, the new securities are to be delivered to the Custodian;

         7)  Upon the sale of such securities for the account of the Trust, to
the  broker  or its  clearing  agent,  against a  receipt,  for  examination  in
accordance with "street  delivery"  custom;  provided that in any such case, the
Custodian shall have no
<PAGE>
responsibility  or  liability  for any loss  arising  from the  delivery of such
securities  prior to receiving  payment for such securities  except as may arise
from the Custodian's own negligence or willful misconduct;

         8)  For exchange or conversion pursuant to any plan of merger, 
consolidation,   recapitalization,   reorganization   or   readjustment  of  the
securities  of the issuer of such  securities,  or  pursuant to  provisions  for
conversion  contained in such securities,  or pursuant to any deposit agreement;

         10) For delivery in  connection  with any loans of  securities
made by the Trust,  but only against  receipt of adequate  collateral  as agreed
upon from time to time by the Custodian and the Trust,  which may be in the form
of cash or obligations issued by the United States  government,  its agencies or
instrumentalities, except that in connection with any loans for which collateral
is to be credited to the Custodian's account in the book-entry system authorized
by the U.S. Department of the Treasury, the Custodian will not be held liable or
responsible  for the  delivery  of  securities  owned by the Trust  prior to the

escrow or other arrangements in connection with transactions by the Trust;

         13) For delivery in accordance with the provisions of any agreement

to time the Trust's currently  effective  prospectus and statement of additional
information ("prospectus"), in satisfaction of requests by holders of Shares for
repurchase or redemption; and

         15) For any other proper corporate purpose, but only upon receipt of,
in addition to Proper  Instructions,  a certified  copy of a  resolution  of the
Board of  Trustees  or of the  Executive  Committee  signed by an officer of the
Trust and  certified by the Secretary or an Assistant  Secretary,  setting forth
the purpose for which such delivery is to be made,  declaring such purpose to be
a proper corporate purpose, and naming the person or persons to whom delivery of
such securities shall be made.

2.3.     Registration of Securities. Securities held by the Custodian (other
than bearer  securities)  shall be registered in the name of the Trust or in the
name of any  nominee of the Trust or in the name of any  nominee of the Trust or
of any nominee of the Custodian  which
<PAGE>
nominee  shall be  assigned  exclusively  to the  Trust,  unless  the  Trust has
authorized  in writing  the  appointment  of a nominee to be used in common with
other registered  investment companies having the same investment adviser as the
Trust, or in the name or nominee name of any agent appointed pursuant to Section
2.11 or in the name or nominee name of any  subcustodian  appointed  pursuant to
Article 1. All securities accepted by the Custodian on behalf of the Trust under
the terms of this  Contract  shall be in "street  name" or other  good  delivery
form.

2.4.     Bank Accounts. The Custodian shall open and maintain a separate bank
account or  accounts  (the  "Trust's  Account or  Accounts")  in the name of the
Trust,  subject only to draft or order by the Custodian  acting  pursuant to the
terms of this Contract,  and shall hold in such Account or Accounts,  subject to
the  provisions  hereof,  all cash received by it from or for the account of the
Trust, other than cash maintained by the Trust in a bank Account established and
used in  accordance  with Rule 17f-3 under the  Investment  Company Act of 1940.
Funds held by the  Custodian  for the Trust may be deposited by it to its credit
as Custodian in the Banking  Department  of the Custodian or in such other banks
or trust  companies as it may in its  discretion  deem  necessary or  desirable;
provided,  however,  that every such bank or trust company shall be qualified to
act as a custodian  under the Investment  Company Act of 1940 and that each such
bank or trust company and the funds to be deposited with each such bank or trust
company  shall be approved by vote of a majority of the Board of Trustees of the
Trust.  Such funds  shall be  deposited  by the  Custodian  in its  capacity  as
Custodian and shall be withdrawable by the Custodian only in that capacity.

2.5.     Payments for Shares. The Custodian shall receive from the distributor

<PAGE>

between the Trust and the Custodian, the Custodian shall, upon the receipt of

         1)  invest in such instruments as may be set forth in such instruments
as may be set forth in such instructions on the same day as received all federal
funds received after a time agreed upon between the Custodian and the Trust; and

         2)  make federal funds available to the Trust as of specified times
agreed  upon from time to time by the Trust and the  Custodian  in the amount of

income and other payments with respect to registered  securities  held hereunder
to which the Trust shall be entitled  either by law or pursuant to custom in the
securities  business,  and shall  collect on a timely basis all income and other
payments  with  respect to bearer  securities  if, on the date of payment by the
issuer,  such  securities  are held by the  Custodian or agent thereof and shall
credit such income,  as collected,  to the Trust's  custodian  account.  Without
limiting the generality of the foregoing, the Custodian shall detach and present
for payment all coupons and other income  items  requiring  presentation  as and
when they become due and shall  collect  interest  when due on  securities  held
hereunder.  Income due the Trust on securities loaned pursuant to the provisions
of Section 2.2 (10) shall be the responsibility of the Trust. The Custodian will
have no duty or  responsibility in connection  therewith,  other than to provide
the Trust with such  information or data as may be necessary to assist the Trust
in arranging for the timely delivery to the Custodian of the income to which the
Trust is properly entitled.

2.8.     Payment of Trust Monies.  Upon receipt of Proper Instructions, which

<PAGE>
of the Trust in the following cases only:

         1)  Upon the purchase of securities, for the account of the Trust but
only (a) against the delivery of such  securities to the Custodian (or any bank,
banking  firm or trust  company  doing  business in the United  States or abroad
which is qualified under the Investment Company Act of 1940, as amended,  to act
as a custodian  and has been  designated  by the Custodian as its agent for this
purpose)  registered in the name of the Trust or in the name of a nominee of the
Custodian referred to in Section 2.3 hereof or in proper form for transfer;  (b)
in the case of a purchase  effected through a Securities  System,  in accordance
with the  conditions  set forth in Section  2.12  hereof;  or (c) in the case of
repurchase  agreements  entered  into  between the Trust and the  Custodian,  or
another bank, or a broker-dealer which is a member of NASD, (i) against delivery
of the securities  either in certificate  form or through an entry crediting the
Custodian's  account at the Federal  Reserve Bank with such  securities  or (ii)
against delivery of the receipt  evidencing  purchase by the Trust of securities
owned by the  Custodian  along with  written  evidence of the  agreement  by the
Custodian to repurchase such securities from the Trust;

         2)  In connection with conversion, exchange or surrender of securities
owned by the Trust as set forth in Section 2.2 hereof;

         3)  For the redemption or repurchase of Shares issued by the Trust as
set forth in Section 2.10 hereof;

         4)  For the payment of any expense or liability incurred by the Trust,
including  but not  limited to the  following  payments  for the  account of the
Trust: interest, taxes, management,  accounting,  transfer agent and legal fees,
and  operating  expenses of the Trust  whether or not such expenses are to be in
whole or part capitalized or treated as deferred expenses;
<PAGE>

         5)  For the payment of any dividends on Shares of the Trust declared
pursuant to the governing documents of the Trust;

         6)  For payment of the amount of dividends received in respect of
securities sold short;

         7)  For any other proper purpose,  but only upon receipt of, in
addition to Proper  Instructions,  a certified copy of a resolution of the Board
of Trustees or of the  Executive  Committee of the Trust signed by an officer of
the Trust and  certified by its  Secretary or an  Assistant  Secretary,  setting
forth the purpose for which such payment is to be made,  declaring  such purpose
to be a proper purpose, and naming the person or persons to whom such payment is
to be made.

2.9.     Liability for Payment in Advance of Receipt of Securities Purchased. In
any and every case where payment for purchase of  securities  for the account of
the Trust is made by the  Custodian  in advance  of  receipt  of the  securities
purchased in the absence of specific written  instructions  from the Trust to so
pay in advance,  the Custodian shall be absolutely  liable to the Trust for such
securities  to the same  extent as if the  securities  had been  received by the
Custodian,  except that in the case of repurchase agreements entered into by the
Trust with a bank which is a member of the Federal Reserve System, the Custodian
may  transfer  funds to the account of such bank prior to the receipt of written
evidence that the securities  subject to such  repurchase  agreements  have been
transferred  by  book-entry  into a  segregated  non-proprietary  account of the
Custodian  maintained  with  the  Federal  Reserve  Bank  of  Boston  or of  the
safekeeping  receipt,  provided  that  such  securities  have  in  fact  been so
transferred by book-entry.

2.10.    Payments for Repurchases or Redemptions of Shares of the Trust. From
such funds as may be available for the purpose but subject to the limitations of
the  Declaration of Trust and any  applicable  votes of the Board of Trustees of
the Trust pursuant  thereto,  the Custodian shall,  upon receipt of instructions
from the Transfer  Agent,  make funds
<PAGE>
available  for payment to holders of Shares who have  delivered  to the Transfer
Agent a request for redemption or repurchase of their Shares. In connection with
the redemption or repurchase of Shares of the Trust, the Custodian is authorized
upon receipt of instructions from the Transfer Agent to wire funds to or through
a commercial bank designated by the redeeming  shareholders.  In connection with
the redemption or repurchase of Shares of the Trust,  the Custodian  shall honor
checks  drawn on the  Custodian  by a holder of Shares,  which  checks have been
furnished by the Trust to the holder of Shares,  when presented to the Custodian
in accordance with such procedures and controls as are mutually agreed upon from
time to time between the Trust and the Custodian.

2.11.    Appointment of Agents. The Custodian  may at any time or times in its

<PAGE>

         5)  The Custodian shall have received the initial or annual
certificate, as the case may be, required by Article 9 hereof;

transmit promptly to the Trust all written information received by the Custodian
from issuers of the  securities  whose tender or exchange is sought and from the
party (or his agents) making the tender or exchange  offer. If the Trust desires
to take action with  respect to any tender  offer,  exchange  offer or any other
similar  transaction,
<PAGE>
the Trust shall notify the  Custodian at least three  business days prior to the
date on which the Custodian is to take such action.

2.17.    Proper Instructions. Proper Instructions as used throughout this
Article 2 means a writing  signed or  initialed by one or more person or persons
as the Board of  Trustees  shall  have from time to time  authorized.  Each such
writing  shall  set  forth  the  specific  transaction  or type  of  transaction
involved, including a specific statement of the purpose for which such action is
requested.  Oral  instructions  will be considered  Proper  Instructions  if the
Custodian  reasonably believes them to have been given by a person authorized to
give such instructions with respect to the transaction involved. The Trust shall
cause all oral  instructions  to be  confirmed  in  writing.  Upon  receipt of a
certificate of the Secretary or an Assistant  Secretary as to the  authorization
by the Board of Trustees of the Trust  accompanied by a detailed  description of
procedures  approved by the Board of Trustees,  Proper  Instructions may include
communications  effected  directly  between   electro-mechanical  or  electronic

such procedures afford adequate safeguards for the Trust's assets.

2.18.    Actions Permitted without Express Authority.  The Custodian may in its
discretion, without express authority from the Trust:

         1)  make payments to itself or others for minor expenses of handling
securities or other similar  items  relating to its duties under this  Contract,
provided that all such payments shall be accounted for to the Trust;

         2)  surrender securities in temporary form for securities in definitive

with the  securities  and property of the Trust except as otherwise  directed by
the Board of Trustees of the Trust.
<PAGE>

2.19.    Evidence of Authority. The Custodian shall be protected in acting upon
any instructions,  notice, request, consent,  certificate or other instrument or
paper  believed by it to be genuine and to have been properly  executed by or on
behalf of the Trust.  The Custodian may receive and accept a certified copy of a
vote of the Board of Trustees  of the Trust as  conclusive  evidence  (a) of the
authority  of any  person  to act in  accordance  with  such  vote or (b) of any
determination  or of any  action  by  the  Board  of  Trustees  pursuant  to the
Declaration  of Trust as described in such vote, and such vote may be considered
as in full force and effect until receipt by the Custodian of written  notice to
the contrary.

Calculation of Net Asset Value and Net Income.

         The Custodian shall cooperate with and supply necessary  information to
the entity or entities  appointed  by the Board of Trustees of the Trust to keep
the books of account of the Trust  and/or  compute the net asset value per share
of the  outstanding  shares of the Trust or, if  directed in writing to do so by
the Trust, shall itself keep such books of account and/or compute such net asset
value per share.  If so directed,  the Custodian  shall also calculate daily the
net  income  of the  Trust  as  described  in the  Trust's  currently  effective
prospectus  shall  advise the Trust and the  Transfer  Agent  daily of the total
amounts of such net income  and, if  instructed  in writing by an officer of the
Trust to do so, shall advise the Transfer Agent  periodically of the division of
such net income among its various components.  The calculations of the net asset
value per share and the daily  income of the Trust  shall be made at the time or
times described from time to time in the Trust's currently effective prospectus.

4.       Records.

         The  Custodian  shall create and  maintain all records  relating to its
activities and  obligations  under this Contract in such manner as will meet the
obligations  of the  Trust  under  the  Investment  Company  Act of  1940,  with
particular attention to Section 31 thereof and Rules 31a-1 and 31a-2 thereunder,
applicable federal and state tax laws and any other law or administrative  rules
or procedures  which may be  applicable to the Trust.  All such records shall be
the  property
<PAGE>
of the Trust and shall at all times  during the  regular  business  hours of the
Custodian  be open for  inspection  by duly  authorized  officers,  employees or
agents of the Trust and  employees  and agents of the  Securities  and  Exchange
Commission. The Custodian shall, at the Trust's request, supply the Trust with a
tabulation of securities owned by the Trust and held by the Custodian and shall,
when  requested  to do so by the  Trust  and for such  compensation  as shall be
agreed upon between the Trust and the Custodian,  include certificate numbers in
such tabulations.

5.       Opinion of Trust's Independent Accountant.

         The Custodian shall take all reasonable  action,  as the Trust may from
time to time request,  to obtain from year to year  favorable  opinions from the
Trust's  independent  accountants  with respect to its  activities  hereunder in
connection  with the  preparation  of the Trust's  Form N-lA,  and Form N-SAR or
other annual reports to the Securities and Exchange  Commission and with respect
to any other requirements of such Commission.

6.       Reports to Trust by Independent Public Accountants.

         The  Custodian  shall  provide the Trust at such times as the Trust may
reasonably  require,  with  reports by  independent  public  accountants  on the
accounting system,  internal  accounting control and procedures for safeguarding
securities,  futures  contracts  and  options  on futures  contracts,  including
securities  deposited and/or maintained in a Securities System,  relating to the
services  provided by the Custodian  under this  Contract;  such reports,  which
shall be of sufficient  scope and in  sufficient  detail,  as may  reasonably be
required  by the  Trust  to  provide  reasonable  assurance  that  any  material
inadequacies  would be disclosed by such examination,  and, if there are no such
inadequacies, shall so state.

7.       Compensation of Custodian.

         The  Custodian  shall be entitled to  reasonable  compensation  for its
services and expenses as Custodian, as agreed upon from time to time between the
Trust and the Custodian.

8.       Responsibility of Custodian.

         So long as and to the extent that it is in the  exercise of  reasonable
care,  the  Custodian  shall  not be  responsible  for the  title, validity or
genuineness of any property or evidence of title
<PAGE>
thereto received by it or delivered by it pursuant to this Contract and shall be
held harmless in acting upon any notice, request, consent,  certificate or other
instrument  reasonably  believed  by it to be  genuine  and to be  signed by the
proper  party  or  parties.  The  Custodian  shall  be held to the  exercise  of
reasonable  care in carrying out the  provisions  of this  Contract but shall be
kept indemnified by the Trust  transaction  taken or omitted by it in the proper
execution of  instructions  from the Trust.  It shall be entitled to rely on and
may act upon advice of counsel for the Trust on all matters and shall be without
liability for any action  reasonably  taken or omitted  pursuant to such advice.
Notwithstanding the foregoing,  the responsibility of the Custodian with respect
to  redemptions  effected  by  check  shall  be in  accordance  with a  separate
Agreement entered into between the Custodian and the Trust.

         The Trust agrees to indemnify  and hold  harmless the Custodian and its
nominee from and against all taxes, charges, expenses,  assessments,  claims and
liabilities  (including  counsel  fees)  incurred or assessed  against it or its
nominee in connection with the performance of this Contract,  except such as may
arise from it or its nominee's own negligent action, negligent failure to act or
willful  misconduct.  The  Custodian is  authorized to charge any account of the
applicable  Trust for such  items and its fees.  To secure  any such  authorized
charges and any advances of cash or  securities  made by the Custodian to or for
the benefit of the Trust for any purpose which results in the Trust incurring an
overdraft  at the end of any  business  day or for  extraordinary  or  emergency
purposes  during any business  day, the Trust hereby  grants to the  Custodian a
security interest in and pledges to the Custodian  securities held for it by the
Custodian,  in an amount not to exceed five percent of the Trust's gross assets,
the specific  securities  to be  designated  in writing from time to time by the
Trust or its  investment  adviser (the "Pledged  Securities").  Should the Trust
fail to repay promptly any advances of cash or securities,  the Custodian  shall
be entitled to use available cash and to dispose of the Pledged Securities as is
necessary to repay any such advances.
<PAGE>

9.       Effective Period, Termination and Amendment.

         This  Contract  shall  become  effective  as of  its  execution,  shall
continue in full force and effect until terminated as hereinafter provided,  may
be  amended at any time by mutual  agreement  of the  parties  hereto and may be
terminated  by either  party by an  instrument  in writing  delivered or mailed,
postage prepaid to the other party,  such  termination to take effect not sooner
than  thirty (30) days after the date of such  delivery  or  mailing;  provided,
however  that the  Custodian  shall not act  under  Section  2.12  hereof in the
absence of receipt of an initial  certificate  of the  Secretary or an Assistant
Secretary  that the Board of Trustees of the Trust have approved the initial use
of a particular  Securities  System and the receipt of an annual  certificate of
the Secretary or an Assistant  Secretary that the Board of Trustees has reviewed
the use by the Trust of such Securities System, as required in each case by Rule
17f-4 under the Investment  Company Act of 1940, as amended;  provided  further,
however,  that  the  Trust  shall  not  amend  or  terminate  this  Contract  in
contravention of any applicable federal or state  regulations,  or any provision
of the Declaration of Trust, and (b) that the Trust may at any time by action of
its Board of  Trustees  (i)  substitute  another  bank or trust  company for the
Custodian  by  giving  notice  as  described  above  to the  Custodian  or  (ii)
immediately  terminate  this  Contract  in the  event  of the  appointment  of a
conservator  or receiver for the Custodian or upon the happening of a like event
at the  direction  of an  appropriate  regulatory  agency or court of  competent
jurisdiction.

         Upon termination of the Contract,  the Trust shall pay to the Custodian
such  compensation  as may be due as of the date of such  termination  and shall
likewise reimburse the Custodian for its costs, expenses and disbursements.

10.      Successor Custodian.

         If a successor custodian shall be appointed by the Board of Trustees of
the Trust,  the Custodian  shall,  upon  termination,  deliver to such successor
custodian  at the office of the  Custodian,  duly  endorsed  and in the form for
transfer,  all  securities  then held by it hereunder  and shall  transfer to an
account of the  successor  custodian  all of the  Trust's  securities  held in a
Securities System.
<PAGE>

         If no such successor custodian shall be appointed, the Custodian shall,
in like  manner,  upon  receipt  of a  certified  copy of a vote of the Board of
Trustees of the Trust,  deliver at the office of the Custodian and transfer such
securities, funds and other properties in accordance with such vote.

         In the event that no written order designating a successor custodian or
certified  copy of a vote of the Board of Trustees  shall have been delivered to
the  Custodian  on or  before  the  date  when  such  termination  shall  become
effective, then the Custodian shall have the right to deliver to a bank or trust
company,  which is a "bank" as defined in the Investment Company Act of 1940, of
its own selection,  having an aggregate capital, surplus, and undivided profits,
as  shown by its last  published  report,  of not  less  than  $25,000,000,  all
securities,  funds and other  properties held by the Custodian on behalf of each
applicable  Portfolio and all instruments held by the Custodian relative thereto
and all other  property  held by it under this  Contract  and to  transfer to an
account of such successor  custodian all of the Trust's  securities  held in any
Securities System. Thereafter, such bank or trust company shall be the successor
of the Custodian under this Contract.

         In the event that securities,  funds and other properties remain in the
possession  of the  Custodian  after  the date of  termination  hereof  owing to
failure of the Trust to procure the certified copy of the vote referred to or of
the Board of Trustees to appoint a successor  custodian,  the Custodian shall be
entitled  to fair  compensation  for its  services  during  such  period  as the
Custodian retains possession of such securities,  funds and other properties and
the  provisions of this Contract  relating to the duties and  obligations of the
Custodian shall remain in full force and effect.

11.      Interpretive and Additional Provisions.

         In connection  with the operation of this  Contract,  the Custodian and
the Trust may from time to time agree on such  provisions  interpretive of or in
addition to the  provisions  of this  Contract as may in their joint  opinion be
consistent  with the general tenor of this Contract.  Any such  interpretive  or
additional  provisions shall be in a writing signed by both parties and shall be
<PAGE>
annexed  hereto,  provided that no such  interpretive  or additional  provisions
shall contravene any applicable federal or state regulations or any provision of
the Declaration of Trust of the Trust. No interpretive or additional  provisions
made as provided in the preceding sentence shall be deemed to be an amendment of
this Contract.

12.      Massachusetts Law to Apply.

         This Contract shall be construed and the provisions thereof interpreted
under and in accordance with laws of The Commonwealth of Massachusetts.

13.      Prior Contracts.

         This Contract  supersedes and  terminates,  as of the date hereof,  the
existing custodian  contract between the Trust and the Custodian.  Any reference
to the  custodian  contract  between the Trust and the  Custodian  in  documents
executed prior to the date hereof shall be deemed to refer to this Contract.

         IN WITNESS  WHEREOF,  each of the parties has caused this instrument to
be executed in its name and behalf by its duly authorized representative and its
seal to be hereunder affixed as of the 24th day of May, 1988.

                        AMENDMENT TO CUSTODIAN CONTRACT


         Amendment to Custodian Contract between Massachusetts  Investors Growth
Stock  Fund,  a  business  trust  organized  and  existing  under  the  laws  of
Massachusetts,  having a principal  place of business  at 200  Berkeley  Street,
Boston,  Massachusetts 02116 (hereinafter  called the "Fund"),  and State Street
Bank and Trust Company,  a  Massachusetts  trust  company,  having its principal
place  of  business  at  225  Franklin  Street,   Boston,   Massachusetts  02110
(hereinafter called the "Custodian").

         WHEREAS:  The Fund and the Custodian are parties to a Custodian
Contract dated May 24, l988 (the "Custodian Contract");

         WHEREAS:  The Fund desires that the Custodian  issue a letter of credit
(the  "Letter of  Credit")  on behalf of the Fund for the  benefit of ICI Mutual
Insurance  Company (the "Company") in accordance  with the Continuing  Letter of
Credit and Security  Agreement and that the Fund's  obligations to the Custodian
with respect to the Letter of Credit shall be fully  collateralized at all times
while the Letter of Credit is  outstanding  by, among other  things,  segregated
assets of the Fund equal to 125% of the face  amount to the amount of the Letter
of Credit;

         WHEREAS:  The Custodian Contract provides for the establishment of
segregated accounts for proper Fund purposes upon Proper Instructions (as
defined in the Custodian Contract); and
<PAGE>

         WHEREAS:  The Fund and the Custodian desire to establish a segregated
account to hold the collateral for the Fund's obligations to the Custodian
with respect to the Letter of Credit and to amend the Custodian Contract to
provide for the establishment and maintenance thereof;

         WITNESSETH:  That in consideration of the mutual covenants and
agreements hereinafter contained, the parties hereto hereby amend the
Custodian Contract as follows:

         1.  Capitalized terms used herein without definition shall have the
meanings ascribed to them in the Custodian Contract.

         2.  The Fund hereby instructs the Custodian to establish and maintain a
segregated account (the "Letter of Credit Custody Account") for and in behalf of
the Fund as contemplated by Section 2.13(iv) for the purpose of  collateralizing
the Fund's obligations under this Amendment to the Custodian Contract.

         3.  The Fund shall deposit with the Custodian and the Custodian shall
hold in the Letter of Credit Custody  Account cash, U.S.  government  securities
and  other  high-grade  debt  securities  owned  by the Fund  acceptable  to the
Custodian  (collectively  "Collateral  Securities")  equal  to 125% of the  face
amount to the amount which the Company may draw under the Letter of Credit. Upon
receipt of such Collateral  Securities in the Letter of Credit Custody  Account,
the Custodian shall issue the Letter of Credit to the Company.

         4.  The fund hereby grants to the Custodian a security interest in the
Collateral  Securities from time to time in the Letter of Credit Custody Account
(the  "Collateral")  to secure the performance of the Fund's  obligations to the
Custodian with respect to the Letter of Credit,  including,  without limitation,
under Section  5-114(3) of the Uniform  Commercial Code. The Fund shall register
the pledge of Collateral  and execute and deliver to the  Custodian  such powers
and  instruments  of
<PAGE>
assignment  as may be  requested  by the  Custodian  to evidence and perfect the
limited interest in the Collateral granted hereby.

         5.  The Collateral Securities in the Letter of Credit  Custody  Account
may be  substituted or exchanged  (including  substitutions  or exchanges  which
increase or decrease the  aggregate  value of the  Collateral)  only pursuant to
Proper  Instructions  from the Fund after the Fund notifies the Custodian of the
contemplated  substitution  or  exchange  and the  Custodian  agrees  that  such
substitution or exchange is acceptable to the Custodian.

         6.  Upon any  payment  made  pursuant  to the  Letter  of Credit by the
Custodian  to the  Company,  after  notice to the  company,  the  Custodian  may
withdraw from the Letter of Credit Custody Account  Collateral  Securities in an
amount equal in value to the amount  actually so paid. The Custodian  shall have

                          Shareholder Servicing Agent Agreement

Dear Sirs:

         Massachusetts  Investors  Growth Stock Fund (the "Fund") is an open-end
registered  investment  company.  The  Fund  has  selected  you  to  act  as the
Shareholder  Servicing  Agent  and you  hereby  agree to act as such  Agent  and
perform  the duties and  functions  thereof in the manner and on the  conditions
hereinafter set forth. Accordingly, the Fund hereby agrees with you as follows:

         1.  The Facility.  You represent  that you have the necessary  computer
equipment,  software and other office equipment ("Facility") adequate to perform
the services contemplated hereby as well as for other investment companies (such
investment  companies,  together with the Fund, are herein collectively referred
to as the "MFS  Funds")  for  which  Massachusetts  Financial  Services  Company
("MFS") acts as investment adviser. The Facility is presently located at 50 Milk
Street, Boston, Massachusetts,  and is to be dedicated solely to the performance
of services  for the MFS Funds,  provided  that the  Facility may be utilized to
perform services for others with the prior written permission of the MFS Funds.

         2.  Name. Unless otherwise directed in writing by MFS, you shall
perform the services contemplated hereby under the name "Massachusetts Financial
Service  Center,  Inc.",  which name,  any similar  names and any logos of which
shall remain the property and under the control of MFS. Upon termination of this
Agreement,  you  shall  cease  to use such  name or any  similar  name  within a
reasonable period of time.

         3.  Services to be Performed. As Shareholder Servicing Agent ("Agent"),
you shall be responsible for administering and performing  transfer and dividend
and  distribution  disbursing  and plan agent  functions in connection  with the
issuance,   transfer  and  redemption  of  the  shares  of  beneficial  interest
("Shares"). The details of the operating standards and procedures to be followed
by you shall be  determined  from time to time by agreement  between you and the
Fund.

         4.  Standard  of Service.  As Agent for the Fund,  you agree to provide
service  equal to or better  than  that  provided  by you or  others  furnishing
shareholder  services to other open-end investment  companies  ("Standard") at a
fee  comparable  to the fee paid you for your services  hereunder.  The Standard
shall include at least the following:

             (a) Prompt reconciliation of any differences as to the number of
outstanding  shares between various Facility records or between Facility records
and records of an MFS Fund's Custodian;

             (b) Prompt processing of shareholder correspondence and of other
matters requiring action by you;
<PAGE>

             (c) Prompt clearance of any daily volume backlog;

             (d) Providing innovative services and technological improvements;

             (e) Meeting the requirements of any governmental authority having
jurisdiction over you or the Fund; and

             (f) Prompt reconciliation of all bank accounts under your control
belonging to the Fund or MFS.

         If any MFS Fund  serviced  by you is  reasonably  of the view  that the
service  provided by you does not meet the  Standard,  it shall give you written
notice specifying the particulars,  and you then shall have 120 days in which to
restore the service so that it meets the Standard, except that such period shall
be 180 days with respect to meeting that portion of the Standard described above
in item (d) of this  paragraph  4. If at the end of such period the Fund remains
reasonably  of the view that the service  provided  by you,  in the  particulars
specified,  does  not  meet the  Standard,  then the MFS Fund or Funds  having a
majority of the accounts for which you are then Agent may, by appropriate action
(including the  concurrence  of a majority of the Trustees or Directors,  as the
case may be, of such MFS Fund or Funds who are not  interested  persons of MFS),
elect to terminate  this  Agreement  for cause as to all such Funds upon 90 days
notice to you. Upon termination hereof, the Fund shall pay you such compensation
as may be due to you as of the  date of such  termination,  and  shall  likewise
reimburse you for any costs, expenses, and disbursements  reasonably incurred by
you to such date in the performance of your duties hereunder.

         5.  Purchase of Facility.  In the event that notice of  termination  of
this Agreement has been given pursuant to the provisions of paragraph 14 hereof,
for cause as defined in  paragraph 4 hereof,  the MFS Funds have the right,  but
shall not be required  (a) to purchase  the  Facility  and assume the  unexpired
portion of any leases of equipment or real estate  relating to the Facility from
you at a price equal to your unrecovered  acquisition value (as supported by the
schedules and records used in  determining  monthly  billings) of the machinery,
equipment,  software, furniture, fixtures and leasehold improvements included in
the  Facility,  and (b) to negotiate  with  persons then  employed by you in the
operation  of the  Facility  and to  hire  all of them in  connection  with  the
purchase of the  Facility  from you by the MFS Funds.  You agree to release each
such employee from any contractual  obligations such person may have to you that
may interfere  with such person's  being hired at such time by the MFS Funds and
agree not to interfere  with the  negotiation  and hiring of any such persons at
such time. In the event that the MFS Funds have given notice of  termination  of
this  Agreement  pursuant to the  provisions  of paragraph 14 hereof for reasons
other than cause as defined in paragraph 4 hereof,  the MFS Funds shall purchase
the Facility under the terms and conditions set forth in subsections (a) and (b)
of this paragraph 5.

         You  shall  effect  the  transfer  of the  Facility  pursuant  to  this
paragraph 5 upon the termination date specified in the notice,  or at such other
time as shall be agreed upon by the parties hereto.

         6.  Rights in Data and  Confidentiality.  You agree  that all  records,
data, files, input materials,  reports, forms and other data received,  computed
or stored in the performance of this Agreement are the exclusive property of the
Fund and that all  such  records  and  other  data  shall be  furnished  without
additional  charge,  except for actual  processing costs, to the Fund in machine
readable as well as printed form  immediately upon termination of this Agreement
or at the Fund's request.  You shall safeguard and maintain the  confidentiality
of the Fund's data and information supplied to you by the Fund and you shall not
transfer or disclose the Fund's data to any third party without the Fund's prior
written  consent  unless  compelled  to do so by order of a court or  regulatory
authority.

         7.  Fees. The fee per Fund  shareholder  account  for your  shareholder
services  hereunder  shall not be in excess of such amount as shall be agreed in
writing  between  us.  Such fee shall be
<PAGE>
payable in monthly installments of one-twelfth of the annual fee. Such fee shall
be subject to review at least  annually  and fixed by the  parties in good faith
negotiation on the basis of a statement of the expenses of the Facility prepared
by you,  which  either you or the Fund may  require to be  certified  by a major
accounting firm acceptable to the parties.  The party or parties requesting such
certification shall bear all expenses thereof. In addition to the foregoing fee,
you  will be  reimbursed  by the  Fund  for  out-of-pocket  expenses  reasonably
incurred by you on behalf of the Fund, including but not limited to expenses for
stationery  (including  business  forms  and  checks),  postage,  telephone  and
telegraph  line  and  toll  charges,  and  premiums  for  negotiable  instrument
insurance and similar items.

         8.  Record Keeping.  You will maintain  records in a form acceptable to
the Fund and in compliance  with the rules and  regulation of the Securities and
Exchange  Commission,  including,  but not  limited to,  records  required to be
maintained by Section 31(a) of the Investment  Company Act of 1940 and the rules
thereunder,  which at all  times  will be the  property  of the Fund and will be
available for inspection and use by the Fund.

         9.  Duty of Care and Indemnification. You will at all times act in good
faith in performing your duties hereunder. You will not be liable or responsible
for delays or errors by reason of circumstances  beyond your control,  including
acts of civil or military authority,  national emergencies,  labor difficulties,
fire,  mechanical breakdown beyond your control,  flood or catastrophe,  acts of
God, insurrection,  war, riots or failure beyond your control of transportation,
communication or power supply.  The Fund will indemnify you against and hold you
harmless  from any and all  losses,  claims,  damages,  liabilities  or expenses
(including  reasonable  counsel  fees and  expenses)  resulting  from any claim,
demand,  action or suit not  resulting  from your bad faith or  negligence,  and
arising  out of,  or in  connection  with,  your  duties  on  behalf of the Fund
hereunder.  In  addition,  the Fund  will  indemnify  you  against  and hold you
harmless  from any and all  losses,  claims,  damages,  liabilities  or expenses
(including  reasonable  counsel  fees and  expenses)  resulting  from any claim,
demand,  action  or suit as a  result  of your  acting  in  accordance  with any
instructions  reasonably  believed  by you  to  have  been  executed  or  orally
communicated  by any  person  duly  authorized  by  the  Fund  or its  Principal
Underwriter,  or as a result of acting in accordance with written or oral advice
reasonably  believed by you to have been given by counsel for the Fund,  or as a
result  of  acting  in  accordance  with any  instrument  or  share  certificate
reasonably  believed by you to have been  genuine and signed,  countersigned  or
executed by any person or persons authorized to sign, countersign or execute the
same (unless  contributed to by your gross negligence or bad faith). In any case
in which the Fund may be asked to indemnify you or hold you  harmless,  the Fund
shall be advised of all pertinent facts concerning the situation in question and
you will use reasonable care to identify and notify the Fund promptly concerning
any  situation  which  presents  or  appears  likely  to  present  a  claim  for
indemnification  against the Fund.  The Fund shall have the option to defend you
against any claim which may be the subject of this  indemnification,  and in the
event that the Fund so elects such defense shall be conducted by counsel  chosen
by the Fund and satisfactory to you and it will so notify you, and thereupon the
Fund shall  take over  complete  defense  of the claim and you shall  sustain no
further  legal  or  other   expenses  in  such  situation  for  which  you  seek
indemnification  under  this  paragraph,  except the  expense of any  additional
counsel  retained  by you.  You will in no case  confess  any  claim or make any
compromise  in any case in which the Fund will be asked to indemnify  you except
with the Fund's prior written  consent.  The  obligations  of the parties hereto
under this paragraph shall survive the termination of this Agreement.

         If any officer of the Fund shall no longer be vested with  authority to
sign for the Fund, written notice thereof shall forthwith be given to you by the
Fund and until receipt of such notice by it, you shall be fully  indemnified and
held harmless by the Fund in recognizing  and acting upon  certificates or other
instruments bearing the signatures or facsimile signatures of such officer.

         10. Insurance.  You will notify the Fund should any of your insurance
coverage,  as set forth on Exhibit A hereto,  be changed  for any  reason,  such
notification to include the date of change and reason or reasons therefor.
<PAGE>

         11. Notices.  All notices or other communications hereunder shall be in
writing  and  shall be  deemed  sufficient  if  mailed  to  either  party at the
addresses set forth in this Agreement, or at such other addresses as the parties
hereto may designate by notice to each other.

         12. Further Assurances.  Each party agrees to perform such further acts
and execute such further  documents as are necessary to effectuate  the purposes
hereof.

         13. Use of a Sub- or  Co-Transfer  Agent.  Notwithstanding  any  other
provision of this Agreement,  it is expressly understood and agreed that you are
authorized in the performance of your duties  hereunder to employ,  from time to
time, one or more Sub-Transfer Agents and/or Co-Transfer Agents.

         14. Termination. Neither this Agreement nor any provision hereof may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing, which, except in the case of termination,  shall be signed by the party
against which  enforcement of such change waiver or discharge is sought.  Except
as  otherwise  provided in paragraph 4 hereof,  this  Agreement  shall  continue
indefinitely  until  terminated by 90 days' written  notice given by the Fund to
you or by you to the Fund,  provided that the Fund may terminate  this Agreement
upon 15 days'  written  notice  of  termination  and  election  of the  right to
purchase the Facility  pursuant to the  provisions  of paragraph 5 hereof.  Upon
termination  hereof,  the Fund shall pay you such  compensation as may be due to
you as of the date of such termination, and shall likewise reimburse you for any
costs,  expenses,  and disbursements  reasonably incurred by you to such date in
the performance of your duties  hereunder.  You agree to cooperate with the Fund
and provide all necessary  assistance in effectuating an orderly transition upon
termination of this Agreement.

         15. Successor.  In the event that in  connection  with  termination  a
successor to any of your duties or  responsibilities  hereunder is designated by
the Fund by written notice to you, you will,  promptly upon such termination and
at the expense of the Fund,  transfer to such  successor a certified list of the
shareholders of the Fund (with name,  address and tax  identification  or Social
Security number) an historical record of the account of each shareholder and the
status thereof, and all other relevant books, records, correspondence, and other
data  established or maintained by you under this  Agreement in form  reasonably
acceptable  to the Fund (if such  form  differs  from the form in which you have
maintained  the  same,  the  Fund  shall  pay  any  expenses   associated   with
transferring  the same to such form), and will cooperate in the transfer of such
duties  and  responsibilities,  including  provision  for  assistance  from your
cognizant  personnel in the  establishment  of books,  records and other data by
such successor.

         16. Miscellaneous.  This Agreement  shall be construed and enforced in
accordance with and governed by the laws of the  Commonwealth of  Massachusetts.
The captions in this  Agreement are included for  convenience  of reference only
and in no way define or delimit any of the provisions hereof or otherwise affect
their construction or effect.  This Agreement may be executed  simultaneously in
two or more  counterparts,  each of which shall be deemed an original but all of
which  taken  together  shall  constitute  one and  the  same  instrument.  This
Agreement  has
<PAGE>
been executed on behalf of the Fund by the undersigned not individually,  but in
the capacity  indicated,  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.

                                       Very truly yours,

         PLAN OF DISTRIBUTION with respect to the shares of beneficial interest
to be designated "Class C" of [NAME OF FUND] (the "Fund"),  a series of [NAME OF
TRUST]    (the    "Trust")    a    Massachusetts     business    trust,    dated
_____________________________, 1993.

                                  WITNESSETH:


         WHEREAS,  the Trust is engaged in business  as an  open-end  management
investment  company and is registered under the Investment  Company Act of 1940,
as amended (collectively with the rules and regulations  promulgated thereunder,
the "1940 Act"); and

         WHEREAS,  the Trust  intends to  distribute  the  shares of  beneficial
interest  (without  par  value)  of the  Fund  designated  Class C  Shares  (the
"Shares") in accordance with Rule 12b-1 under the 1940 Act ("Rule  12b-1"),  and
desires to adopt this  Distribution  Plan (the "Plan") as a plan of distribution
pursuant to such Rule; and

         WHEREAS, the Trust desires for MFS Fund Distributors,  Inc., a Delaware
corporation ("FSI"), to provide certain distribution  services for the Fund (the
"Distributor"); and

         WHEREAS,  the Trust has  entered  into a  distribution  agreement  (the
"Distribution  Agreement")  (in a form  approved by the Board of Trustees of the
Trust in a manner  specified in such Rule 12b-1) with the  Distributor,  whereby
the Distributor will provide facilities and personnel and render services to the
Fund in  connection  with the  offering  and  distribution  of the  Shares  (the
"Distribution Agreement"); and

         WHEREAS,  the Trust  recognizes and agrees that (a) the Distributor may
retain the services of firms or individuals to act as dealers (the "Dealers") of
the Shares in connection  with the offering of Shares,  and (b) the  Distributor
may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust recognizes and agrees that the Distributor may (but
is not required to) impose certain deferred sales charges in connection with the
repurchase  of Shares by the Fund,  and the  Distributor  may retain (or receive
from the Fund, as the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class C
shareholders;
<PAGE>

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1.  As specified in the Distribution  Agreement, the Distributor shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
commissions payable to Dealers (including any ongoing maintenance  commissions),
all expenses of printing (excluding  typesetting) and distributing  prospectuses
to prospective  shareholders  and providing  such other related  services as are
reasonably necessary in connection therewith.

         2.  The Distributor shall bear all distribution-related expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3.  It is understood that the  Distributor may (but is not required to)
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund and the  Distributor may retain (or receive from the Fund, as
the case may be) all such deferred  sales charges.  As additional  consideration
for all services  performed  and  expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.75% per annum of the
Fund's average daily net assets attributable to the Shares.

         4.  As partial consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different  dealer  qualification  standards that may be established from time to
time by the Distributor.  The Distributor  shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor  will then pay these fees to dealers on behalf of the Fund or retain
them in accordance with this paragraph.

         5.  The Fund understands that agreements between the Distributor and
the Dealers may provide for payment of commissions to Dealers in connection with
the  sales  of  Shares  and  may  provide  for a  portion  (which  may be all or
substantially  all) of the fees payable by the Fund to the Distributor under the
Distribution  Agreement  to be  paid  by  the  Distributor  to  the  Dealers  in
consideration  of the  Dealer's  services as a dealer of the  Shares.  Except as
described  in  paragraph 4, nothing in this Plan shall be construed as requiring
the Fund to make any  payment  to any Dealer or to have any  obligations  to any
Dealer in connection  with services as a dealer of the Shares.  The  Distributor
shall  agree  and  undertake  that  any  agreement   entered  into  between  the
Distributor  and any Dealer shall provide that,  except as provided in paragraph
4, such Dealer shall look solely to the  Distributor  for  compensation  for its
services thereunder and that in no event shall such Dealer seek any payment from
the Fund.

         6.  The Fund shall pay all fees and expenses of any independent
auditor,  legal counsel,  investment  adviser,  administrator,  transfer  agent,
custodian,  shareholder servicing agent,  registrar or dividend disbursing agent
of the Fund;  expenses  of  distributing  and  redeeming  Shares  and  servicing
shareholder accounts; expenses of preparing,  printing and mailing prospectuses,

Distributor  shall  be  responsible  for the  distribution-related  expenses  as
provided in paragraphs 1 and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8.  This Plan shall become effective  upon (a) approval by a vote of at
least a "majority  of the  outstanding  voting  securities"  of Class C, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9.  This Plan shall continue in effect indefinitely; provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10. This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the outstanding  voting securities" of Class C and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class C.

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12. While this Plan is in effect, the selection and nomination of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be construed in accordance with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

be affected thereby.
