                  MASSACHUSETTS FINANCIAL SERVICES COMPANY
                                 MFS FUNDS
                           STATEMENT OF POLICY ON
                      PERSONAL SECURITIES TRANSACTIONS
                              (CODE OF ETHICS)

                   AS ADOPTED BY THE MFS AUDIT COMMITTEE
            AND THE BOARDS OF TRUSTEES/MANAGERS OF THE MFS FUNDS
                     EFFECTIVE AS OF SEPTEMBER 1, 2000

      As an investment advisory organization with substantial responsibilities
to clients, Massachusetts Financial Services Company ("MFS") has an obligation
to implement and maintain a meaningful policy governing the securities
transactions of its Directors, officers and employees ("MFS
representatives").(1) In addition, each of the investment companies registered
under the Investment Company Act of 1940, as amended (the "1940 Act") with
respect to which MFS, or a subsidiary of MFS, acts as investment adviser
(collectively, the "MFS Funds") is required to adopt such a policy governing the
securities transactions of its Trustees and officers ("Fund representatives").
Accordingly, this policy has been adopted by the MFS Audit Committee and by each
of the MFS Funds. This policy is intended to minimize conflicts of interest, and
even the appearance of conflicts of interest, between members of the MFS
organization and its clients in the securities markets as well as to effect
compliance with the 1940 Act, the Investment Advisers Act of 1940, as amended,
and the Securities Exchange Act of 1934, as amended. This policy inevitably will
restrict MFS representatives and Fund representatives in their securities
transactions, but this is the necessary consequence of undertaking to furnish
investment advice to clients or serving as a Fund representative. In addition to
complying with the specific rules, all MFS representatives and Fund
representatives must be sensitive to the need to recognize any conflict, or the
appearance of conflict, of interest whether or not covered by the rules. When
such situations occur, the interests of the MFS Funds and MFS' other clients
must supersede the interest of MFS representatives and Fund representatives.

      1. GENERAL FIDUCIARY PRINCIPLES. All personal investment activities
conducted by MFS representatives and Fund representatives are subject to
compliance with the following principles: (i) the duty at all times to place the
interests of MFS' clients first; (ii) the requirement that all personal
securities transactions be conducted consistent with this Code of Ethics and in
such a manner as to avoid any actual or potential conflict of interest or any
abuse of an individual's position of trust and responsibility; and (iii) the
fundamental standard that MFS representatives and Fund representatives should
not take inappropriate advantage of their positions.



--------
      (1) Employees of MFS Institutional Advisors, Inc., MFS Fund Distributors,
Inc., MFS Retirement Services, Inc., MFS International Ltd., MFS International
(U.K.) Ltd., MFS Service Center, Inc., Vertex Investment Management Inc. and MFS
Heritage Trust Company also are covered by this Code of Ethics.
<PAGE>

      2. APPLICABILITY OF RESTRICTIONS AND PROCEDURES.

      CATEGORIES OF PERSONNEL. In recognition of the different circumstances
surrounding each MFS representative's and Fund representative's employment or
position, various categories of representatives are subject to different
restrictions under this Code of Ethics. For purposes of applying this Code of
Ethics, MFS representatives and Fund representatives are divided into the
general categories of Portfolio Managers, Investment Personnel, Access
Persons(2) and Non-Access Persons, as each such term is defined in Appendix A to
this Code of Ethics, as amended from time to time by the MFS Audit Committee and
the MFS Funds. Any Fund representative who is also an MFS representative shall
be subject to all requirements applicable to MFS representatives.

      NOTE: ANY NON-ACCESS PERSON WHO RECEIVES ANY INFORMATION ABOUT ANY
PARTICULAR INVESTMENT RECOMMENDATION OR EXECUTED OR PROPOSED TRANSACTION FOR ANY
MFS CLIENT IS REQUIRED TO COMPLY WITH ALL PRECLEARANCE AND OTHER REQUIREMENTS OF
THIS CODE OF ETHICS APPLICABLE TO ACCESS PERSONS.

      BENEFICIAL OWNERSHIP. The requirements of this Code of Ethics apply to any
account in which an MFS representative or Fund representative has (i) "direct or
indirect beneficial ownership" or (ii) any "direct or indirect influence or
control." Under applicable SEC interpretations, such "beneficial ownership"
includes accounts of a spouse, minor children and dependent relatives resident
in the MFS representative's or Fund representative's house, as well as any other
contract, relationship, understanding or other arrangement which results in an
opportunity for the MFS representative or Fund representative to profit or share
profits from a transaction in securities.(3)

      SECURITIES. As used in this Code of Ethics, the term "securities" includes
not only publicly traded equity securities, but also privately issued equity
securities, limited partnership interests, shares of closed-end funds, fixed
income securities (including municipal bonds and many types of U.S. Government
securities), futures, options, warrants, rights, swaps, commodities and other
similar instruments. Moreover, the restrictions of this Code of Ethics apply to
transactions by Access Persons involving securities and other instruments
related to, but not necessarily the same as, securities held or to be acquired
on behalf of an MFS client. (See Section 7 for certain exceptions)



--------
      (2) Note that all Portfolio Managers also are Investment Personnel and
Access Persons, and that all Investment Personnel also are Access Persons.

      (3) NOTE: The exception for accounts with respect to which an MFS
representative or Fund representative lacks "direct or indirect influence or
control" is extremely narrow, and should only be relied upon in cases which have
been pre-approved in writing by Stephen E. Cavan or Robert T. Burns of the Legal
Department. Certain "blind trust" arrangements approved by the Legal Department
may be excluded from the preclearance (but not the quarterly reporting)
requirements of this Code of Ethics. Requests for pre-approval of "blind trusts"
should be reviewed first with the Compliance Department.

      3.   RESTRICTIONS ON PERSONAL SECURITIES TRANSACTIONS.

      ALL ACCESS PERSONS. No Access Person shall trade in any security which is
subject to a pending "buy" or "sell" order, or is being considered for purchase
or sale,(4) for a client of MFS until the second business day after such order
is executed or withdrawn or such a transaction is no longer being considered. In
addition, no Access Person shall trade in any security until the third business
day after a research note with respect to such security has been issued or
revised.

      INVESTMENT PERSONNEL. No Investment Personnel shall trade in any security
after an MFS client trades in such security or such security has been considered
for purchase or sale on behalf of an MFS client until: (i) the second business
day following such trade or consideration (in the case of a proposed trade by an
Investment Personnel in the same direction as the MFS client); or (ii) the
eighth calendar day thereafter (in the case of a proposed trade by an Investment
Personnel in the opposite direction from the MFS client's trade).

      PORTFOLIO MANAGERS. No Portfolio Manager shall trade in any security
within at least seven calendar days before or after an MFS client whose account
he or she manages trades in such security or such security has been considered
for purchase or sale on behalf of such an MFS client. Portfolio Managers shall
not be permitted to sell for their own account securities that are held in an
MFS client account that he or she manages. Any Portfolio Manager who feels
inequitably burdened by this restriction may present a written request for an
exemption from the MFS Equity Management Committee.(5) The Committee may, in its
sole discretion, grant appropriate exceptions where warranted by special facts
and circumstances (e.g. selling securities to settle an estate or to acquire a
residence).

      DISGORGEMENT OF PROFITS; CONFIDENTIALITY. Any profits realized on trades
within these proscribed periods must be disgorged to the affected MFS client or,
in the event that the amount to be disgorged is relatively minor or difficult to
allocate, to charity. In addition, no MFS representative shall provide any
information about such transaction or recommendation to any person other than in
connection with the proper execution of such purchase or sale for an MFS
client's account.

      SHORT  SALES.  No  Access  Person  shall  effect  a short  sale in any
      security held in a portfolio managed by MFS.

      OPTIONS AND FUTURES TRANSACTIONS. Access Persons may purchase (to open)
      and sell (to close) call and put options and futures contracts on
      securities, subject to the preclearance and other requirements of this
      Code of Ethics; however, an Access Person may neither buy a put option nor
      write (sell to open) options and futures contracts, in each case on any
      security held in a portfolio managed by MFS. In the case of purchased put
      and call options, the preclearance of the exercise of such options as well
      as their purchase and sale, is required. Preclearance of the exercise of
      purchased put and call options shall be requested on the day before the
      proposed exercise or, if notice to the writer of such options is required
      before the proposed exercise date, the date before notice is proposed to
      be given, setting forth the proposed exercise date as well as the proposed



--------
      (4) A security is deemed to have been "considered for purchase or sale"
when a recommendation to purchase or sell such security has been made and
communicated to a portfolio manager and, with respect to the person making the
recommendation, when such person seriously considers making such a
recommendation.

      (5) Any request for an exemption should be reviewed first with the
Compliance or Legal Department.

<PAGE>

      notice date.(6) Purchases and sales of options or futures contracts to
      "close out" existing options or futures contracts must be precleared.(7)
      INITIAL PUBLIC OFFERINGS. The purchase by Access Persons of securities
      (other than securities of registered open-end investment companies)
      offered at fixed public offering price by underwriters or a selling group
      is prohibited.8 Rights (including rights purchased to acquire an
      additional full share) issued in respect of securities any Access Persons
      owns may be exercised, subject to preclearance; the decision whether or
      not to grant preclearance shall take into account, among other factors,
      whether the investment opportunity should be reserved for an MFS client
      and whether the investment opportunity is being or was offered to the
      individual by virtue of his or her position with MFS.

      PRIVATE PLACEMENTS. Any acquisition by Access Persons of securities issued
      in a private placement is subject to prior approval with the Compliance
      Department in consultation with the Legal Department and other appropriate
      parties. The decision whether or not to grant approval shall take into
      account, among other factors, whether the investment opportunity should be
      reserved for an MFS client and whether the investment opportunity is being
      offered to the individual by virtue of his or her position with MFS.
      Investment Personnel who have been approved to acquire securities in a
      private placement are required to disclose that investment when they play
      a part in any subsequent consideration of an investment in the issuer for
      an MFS client. In such circumstances, the decision to purchase securities
      of the issuer for the MFS client shall be subject to an independent review
      by Investment Personnel with no personal interest in the issuer.

      NOTE: Acquisitions of securities in private placements by country clubs,
      yacht clubs, restaurants and other similar entities need not be
      pre-approved, but are subject to the reporting, disclosure and independent
      review requirements.

      PROHIBITION ON SHORT-TERM TRADING PROFITS. All Investment Personnel are
      prohibited from profiting in the purchase and sale, or sale and purchase,
      of the same (or equivalent) securities within 60 calendar days. Any
      profits realized on such short-term trades must be disgorged to the
      affected MFS client (if any) or, in the event that the amount to be
      disgorged is relatively minor or difficult to allocate, to charity. This
      restriction on short-term trading profits shall not apply to transactions
      exempt from preclearance requirements, as described in Section 7 below.



--------
      (6) Access Persons should note that this requirement may result in their
not being allowed to exercise an option purchased by them on the exercise date
they desire, and in the case of a "European" option on the only date on which
exercise is permitted by the terms of the option.

      (7) Access Persons should note that as a result of this requirement, they
may not be able to obtain preclearance consent to close out an option or futures
contract before the settlement date. If such an option or futures contract is
automatically closed out, the gain, if any, on such transaction will be
disgorged in the manner described above.

      (8) The reason for this rule is that it precludes any possibility that
Access Persons might use MFS' clients' market stature as a means of obtaining
for themselves "hot" issues which otherwise might not be offered to them. In
addition, this rule eliminates the possibility that underwriters and selling
group members might seek by this means to gain favor with individuals in order
to obtain preferences from MFS.
<PAGE>

      It is expected that all MFS representatives will follow these restrictions
in good faith and conduct their personal trading in keeping with the intended
purpose of this Code of Ethics. Any individual should feel free to take up with
the MFS Audit Committee any case in which he or she feels inequitably burdened
by these policies.(9) The MFS Audit Committee may, in its sole discretion, grant
appropriate exceptions from the requirements of this Code of Ethics where
warranted by applicable facts and circumstances.

      4. PRECLEARANCE REQUIREMENTS. In order to facilitate compliance with this
Code of Ethics, preclearance requests must be made and approved before any
transaction may be made by an Access Person or for any other account
beneficially owned by an Access Person. A preclearance request in the form set
forth in MFS' automated Code of Ethics system, as amended from time to time,
should be completed and submitted electronically for any order for an Access
Person's own account or one described in Section 2 above, or, in the case of an
Access Person who wishes to preclear while outside of the Boston area, should
either: (i) be completed in the form attached hereto, as amended from time to
time, signed and submitted by facsimile machine, to the Compliance Department;
or (ii) be submitted by telephone call to the Compliance Department. Any
preclearance request received before 3:00 p.m. on a business day will be
responded to as soon as available on the following business day. Preclearance
requests will be reviewed by Equity and Fixed Income Department personnel who
will be kept apprised of recommendations and orders to purchase and sell
securities on behalf of MFS clients, the completion or cancellation of such
orders and the securities currently held in portfolios managed by MFS. Their
advice will be forwarded to the Compliance Department.

      MAXIMUM NUMBER OF PRECLEARANCE REQUESTS. The preclearance process imposes
significant burdens on the investment and administrative departments within MFS.
Accordingly, no Access Person may submit more than twenty (20) preclearance
requests in any calendar quarter. In special circumstances the MFS Audit
Committee may, in its sole discretion, grant temporary exceptions from this
restriction where warranted by applicable facts and circumstances.(10)

      An Access Person who obtains electronic or written notice from the
Compliance Department indicating consent to an order which the Access Person
proposes to enter for his or her own account or one described in Section 2 above
may execute that order ONLY ON THE DAY WHEN SUCH NOTICE IS RECEIVED unless
otherwise stated on the notice. Such notices will always be electronic or in
writing; however, in the case of an Access Person who wishes to preclear a
transaction while outside the Boston area, the Compliance Department will also
provide oral confirmation of the content of the written notice.

      Preclearance requests may be denied for any number of appropriate reasons,
most of which are confidential. For example, a preclearance request for a
security that is being considered for purchase or sale on behalf of an MFS
client may be denied for an extended period. Accordingly, an Access Person is
not entitled to receive any explanation or reason if his or her preclearance
request is denied, and repetitive requests for an explanation by an Access
Person will be deemed a violation of this Code of Ethics.



--------
      (9) Any request for an exemption should be reviewed first with the
Compliance or Legal Department.

      (10) Any request for an exception should be reviewed first with the
Compliance or Legal Department.
<PAGE>

      SECURITIES SUBJECT TO AUTOMATIC PURCHASES AND SALES FOR MFS CLIENTS.
      Certain MFS funds and institutional accounts are managed such that the
      securities held in such portfolios are regularly purchased or sold on an
      equal proportionate basis so as to preserve specified percentage
      weightings of such securities across such portfolios. Requests to preclear
      purchases of securities held in such portfolios will be denied. Requests
      to sell such securities may be granted, subject to the standard
      preclearance requirements.

      GIFTS AND TRANSFERS. A gift or transfer shall be excluded from the
      preclearance requirements provided that the recipient represents in
      writing that he, she, they or it has no present intention of selling the
      donated security.

      MFS CLOSED-END FUNDS. All transactions effected by any MFS representative
      in shares of any closed-end fund for which MFS or one of its affiliates
      acts as investment adviser shall be subject to preclearance and reporting
      in accordance with this Code of Ethics. Non-Access Persons are exempt from
      the preclearance and reporting requirements set forth in this Code of
      Ethics with respect to transactions in any other type of securities, so
      long as they have not received any information about any particular
      investment recommendation or executed or proposed transaction for any MFS
      client with respect to such security.

      5. DUPLICATE CONFIRMATION STATEMENT REQUIREMENT. In order to implement and
enforce the above policies, every Access Person shall arrange for his or her
broker to send MFS duplicate copies of all confirmation statements issued with
respect to the Access Person's transactions and all periodic statements for such
Access Person's securities accounts (or other accounts beneficially owned by
such Access Person). The Compliance Department will coordinate with brokerage
firms in order to assist Access Persons in complying with this requirement.

      6. REPORTING REQUIREMENT. Each Access Person shall report on or before the
tenth day of each calendar quarter any securities transactions during the prior
quarter in accounts covered by Section 2 above. EMPLOYEES WHO FAIL TO COMPLETE
AND FILE SUCH QUARTERLY REPORTS ON A TIMELY BASIS WILL BE REPORTED TO THE MFS
AUDIT COMMITTEE AND WILL BE SUBJECT TO SANCTIONS. Reports shall be reviewed by
the Compliance Department.

      Any reports filed by a "Disinterested Trustee" (as such term is defined in
Section 12 below) shall be reviewed by the Secretary of the Fund. If the
Secretary of the Fund determines that a violation of this Code of Ethics may
have occurred, he shall submit the pertinent information to counsel for the
Disinterested Trustees. Such counsel shall determine whether a material
violation of this Code of Ethics may have occurred, after considering all
available exemptions and providing the Disinterested Trustee involved with an
opportunity to supply additional information regarding the transaction in
question. If such counsel determines that a material violation of this Code of
Ethics has occurred, they shall so advise the Chairman or President of the Fund
and an ad hoc committee consisting of the Disinterested Trustees of the Fund,
other than the involved Disinterested Trustee, and shall provide the committee
with a report of the matter, including any additional information supplied by
the involved Disinterested Trustee. The committee may impose such sanction as it
deems appropriate.

      In filing the reports for accounts within these rules, please note:

      (i)   Each Access Person must file a report for every calendar quarter
            even if he or she had no reportable transactions in that quarter;
            all such reports shall be completed and submitted in the form set
            forth in MFS' automated Code of Ethics system.

      (ii)  Reports must show any sales, purchases or other acquisitions or
            dispositions, including gifts, exercises of conversion rights and
            exercises or sales of subscription rights. See Section 7 below for
            certain exceptions to this requirement.

      (iii) Reports will be treated confidentially unless a review of particular
            reports with the representative is required by the MFS Audit
            Committee or for legal or compliance purposes.

      (iv)  Reports are made available for review by the Boards of
            Trustees/Managers of the MFS Funds upon their request.

      NOTE: Any Access Person who maintains all of his or her personal
      securities accounts with one or more broker-dealer firms that send
      confirmation and periodic account statements in an electronic format
      approved by the Compliance Department, and who arranges for such firms to
      send such statements (no less frequently than quarterly) required by
      Section 5 above, shall not be required to prepare and file the quarterly
      reports required by this Section 6. However, each such Access Person shall
      be required to verify the accuracy and completeness of all such statements
      on at least an annual basis.

      7.    CERTAIN EXCEPTIONS.

      MUTUAL  FUNDS.  Transactions  in  shares  of any  open-end  investment
companies,  including  funds for which the MFS  organization  is  investment
adviser, need not be precleared or reported.

      CLOSED-END FUNDS. Automatic reinvestments of distributions of closed-end
funds advised by MFS pursuant to dividend reinvestment plans of such funds need
only be reported. All other closed-end fund transactions must be precleared and
reported.

      MFS AND SUN LIFE COMMON STOCK. Transactions in shares of stock of MFS need
not be precleared or reported. Note, however, that transactions in shares of
stock of Sun Life Financial Services of Canada Inc. are subject to preclearance
with the Compliance Department.

      LARGE CAPITALIZATION STOCKS. Transactions in securities issued by
companies with market capitalizations of at least $5 billion generally will be
eligible for automatic preclearance (subject to certain exceptions), but must be
reported and are subject to post-trade monitoring. The Compliance Department
will maintain a list of issuers that meet this market capitalization
requirement. A preclearance request for a large capitalization company will be
denied whenever deemed appropriate.

      U.S. GOVERNMENT SECURITIES. Transactions in U.S. Treasury securities and
other U.S. Government obligations (including options and futures contracts and
other derivatives with respect to such securities and obligations) need not be
precleared or reported.

      DIVIDEND REINVESTMENT PLANS. Automatic reinvestments of dividends in
shares of common stock of public companies often are eligible for an exemption
from preclearance. Any requests for exemptions should be directed to the
Compliance Department.

      OTHER EXCEPTIONS. Transactions in money market instruments and in options
on broad-based indices need not be precleared, although such transactions must
be reported. The types of instruments and indices that are eligible for this
exception are constantly developing; the Compliance Department maintains the
definitive list of eligible instruments and indices. In addition, the following
types of transactions need not be precleared or reported: (i) stock dividends
and stock splits; (ii) foreign currency transactions; and (iii) transactions in
real estate limited partnership interests. For other exceptions from
preclearance or reporting, an MFS representative may contact the Compliance
Department.

      8. DISCLOSURE OF PERSONAL SECURITIES HOLDINGS. All Access Persons are
required to disclose all personal securities holdings within 10 days after
becoming an Access Person (i.e. upon commencement of employment with MFS or
transfer within MFS to an Access Person position) and thereafter on an annual
basis. Reports shall be reviewed by the Compliance Department.

      9. GIFTS, ENTERTAINMENT AND FAVORS. MFS representatives must not make
business decisions that are influenced or appear to be influenced by giving or
accepting gifts, entertainment or favors. Investment Personnel are prohibited
from receiving any gift or other thing of more than de minimis value from any
person or entity that does business with or on behalf of MFS or its clients.
Invitations to an occasional meal, sporting event or other similar activity will
not be deemed to violate this restriction unless the occurrence of such events
is so frequent or lavish as to suggest an impropriety.

      10. SERVICE AS A DIRECTOR. All MFS representatives are prohibited from
serving on the boards of directors of commercial business enterprises, absent
prior authorization by the Management Group based upon a determination that the
board service would be consistent with the interests of MFS' clients. In the
relatively small number of instances in which board service is authorized, MFS
representatives serving as directors may be isolated from other MFS
representatives through "Chinese Wall" or other appropriate procedures.

      11. CERTIFICATION OF COMPLIANCE WITH CODE OF ETHICS. All MFS
representatives and Fund representatives (including Non-Access Persons) shall be
required to certify annually that (i) they have read and understand this Code of
Ethics and recognize that they are subject to its requirements applicable to
them and (ii) they have complied with all requirements of this Code of Ethics
applicable to them, and (in the case of Access Persons) have reported all
personal securities transactions (whether pursuant to quarterly reports from the
Access Person or duplicate confirmation statements and periodic reports from the
Access Person's broker-dealer) required to be reported pursuant to this Code of
Ethics. This certification shall apply to all accounts beneficially owned by an
MFS representative or Fund representative.

      12. BOARDS OF TRUSTEES/MANAGERS OF MFS FUNDS. Any material amendment to
this Code of Ethics shall be subject to the approval by each of the Boards of
Trustees/Managers(including a majority of the Disinterested Trustees/Managers on
each such Board) of each of the MFS Funds. In addition, on at least an annual
basis, MFS shall provide each such Board with a written report that: (i)
describes issues that arose during the preceding year under this Code of Ethics,
including without limitation information about any material violations of this
Code of Ethics and any sanctions imposed with respect to such violations; and
(ii) certifies to each such Board that MFS has adopted procedures reasonably
necessary to prevent Access Persons from violating this Code of Ethics.

      Notwithstanding any provision to the contrary in this Code of Ethics, any
Trustee/Manager of an MFS Fund who is not an "interested person" of such Fund
within the meaning of Section 2(a)(19) of the Investment Company Act (each a
"Disinterested Trustee") shall not be subject to any of the requirements set
forth in Sections 3, 4, 5, 8, 9, 10 or 11 of this Code of Ethics. In addition,
any Disinterested Trustee shall not be subject to the reporting requirements set
forth in Section 6 of this Code of Ethics, except with respect to securities
transactions with respect to which such Disinterested Trustee knew or, in the
ordinary course of fulfilling his or her official duties as a Trustee, should
have known that during the 15-day period immediately before or after the
Trustee's transaction in such security, such security was purchased or sold, or
considered for purchase or sale, for an MFS Fund.

      13. SANCTIONS. Any trading for an MFS representative's or Fund
representative's account which does not evidence a good faith effort to comply
with these rules will be subject to review by the MFS Audit Committee or, in the
case of Disinterested Trustees, by an ad hoc committee in the manner described
in Section 6 above. If the Audit Committee or such ad hoc committee, as
applicable, determines that a violation of this Code of Ethics or its intent has
occurred, it may impose such sanctions as it deems appropriate including
forfeiture of any profit from a transaction and/or termination of employment.
Any violations resulting in sanctions will be reported to the Boards of
Trustees/Managers of the MFS Funds and will be reflected in MFS' compliance
files.

                                 APPENDIX A

                           CERTAIN DEFINED TERMS


      As used in this Code of Ethics, the following shall terms shall have the
meanings set forth below, subject to revision from time to time by the MFS Audit
Committee and the MFS Funds:

      PORTFOLIO MANAGERS -- employees who are authorized to make investment
      decisions for a mutual fund or client portfolio. Note: research analysts
      are deemed to be Portfolio Managers with respect to the entire portfolio
      of any fund managed collectively by a committee of research analysts (e.g.
      MFS Research Fund) except that, for purposes of the restriction on sales
      of securities held in a managed client account set forth in Section 3,
      analysts are deemed to be Portfolio Managers only with respect to
      portfolio securities within the industry they cover.

      INVESTMENT PERSONNEL -- all Portfolio Managers as well as research
      analysts, traders, other members of the Equity Trading, Fixed Income and
      Equity Research Departments, and other MFS representatives who have access
      to confidential portfolio information.

      ACCESS PERSONS -- all Fund representatives (see Section 12 for certain
      exceptions), Portfolio Managers, Investment Personnel and other members of
      the following departments or groups: Institutional Advisors; Compliance;
      Internal Audit; Fund Treasury; Investment Operations; Investment
      Communications; and Technology Services & Solutions ("TS&S") (excluding,
      however, TS&S employees who are employed at Lafayette Corporate Center and
      certain TS&S employees who may be specifically excluded by the Compliance
      or Legal Departments); also included are members of the MFS Management
      Group, the MFS Administrative Committee and the MFS Operations Committee.
      In certain instances, other MFS employees, non-employee consultants and
      other independent contractors may be deemed Access Persons and therefore
      be subject to some or all of the requirements set forth in this Code of

All transactions must be precleared, regardless of their size, except those in
certain specific categories of securities that are exempted under the MFS Code
of Ethics. If necessary, continue on the reverse side. Please note that special
rules apply to the preclearance of option and futures transactions. If the

on the reverse side. Describe the nature of each account in which the
transaction is to take place, i.e., personal, spouse, children, charitable
