MFS(R) LIMITED MATURITY FUND*

Supplement dated August 1, 2002 to the Current Prospectus

This Supplement describes the fund's class 529A, 529B and 529C shares, and it supplements certain information in the fund's Prospectus dated September 1, 2001. The caption headings used in this Supplement correspond with the caption headings used in the Prospectus.

Class 529A, 529B and 529C shares are only offered in conjunction with qualified tuition programs (tuition programs) established in accordance with Section 529 of the Internal Revenue Code (Code). Contributions to these tuition programs may be invested in the fund's class 529A, 529B or 529C shares and certain other MFS funds offering these share classes. Earnings on investments in the fund made through such tuition programs may receive favorable tax treatment under the Code, as described further under the caption "Tax Considerations" below. For information on policies, services and restrictions which apply to your account with the tuition program through which your investment in the fund is made, please refer to the description of the tuition program available from your financial representative (the program description).

1. RISK RETURN SUMMARY

Performance Table. The "Performance Table" is intended to indicate some of the risks of investing in the fund by showing changes in the fund's performance over time. Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not yet have a performance record to report.

2. EXPENSE SUMMARY

Expense Table. This table describes the fees and expenses that you may pay when you buy, redeem and hold shares of the fund.

Shareholder Fees (fees paid directly from your investment):

                                                Class 529A        Class 529B         Class 529C
Maximum Sales Charge (Load) Imposed
    on Purchases (as a percentage of
    offering price)........................          2.50%              0.00%             0.00%


Maximum Deferred Sales Charge (Load) (as a percentage of original purchase
    price or redemption proceeds, whichever
    is less)...............................          0.00%              4.00%             1.00%

Annual Fund Operating Expenses (expenses that are deducted from fund assets):

Management Fees............................          0.40%              0.40%             0.40%

Other Expenses(2)..........................          0.56%              0.56%             0.56%
                                                     -----              -----             -----
Total Annual Fund Operating Expenses(2)....          1.31%              1.96%             1.96%
    Fee Waiver(3)..........................         (0.15)%            (0.05)%           (0.05)%
                                                    -------            -------           -------
    Net Expenses(2)........................          1.16%              1.91%             1.91%


(1) The fund adopted a distribution plan under Rule 12b-1 that permits it to pay marketing and other fees to support the sale and distribution of class 529A, 529B and 529C shares and the services provided to you by your


financial adviser (referred to as distribution and service fees). The maximum distribution and service fees under the plan are 0.50% annually for class 529A shares and 1.00% annually for class 529B and 529C shares. The fund's distributor, MFS Fund Distributors, Inc., has contractually agreed to waive 0.10% annually of the fund's class 529A service fee (see footnote
(3) below). The remaining 0.15% class 529A distribution fee may be imposed only with the approval of the board of trustees which oversees the fund.

(2) "Other Expenses" are estimated for the fund's current fiscal year, and include the program management fee described below under "Management of the Fund." The fund has an expense offset arrangement which reduces the fund's custodian fee based upon the amount of cash maintained by the fund with its custodian and dividend disbursing agent. The fund may also enter into other such arrangements and directed brokerage arrangements (which would also have the effect of reducing the fund's expenses). Any such fee reductions are not reflected in the table. Had these expense reductions been taken into account, "Net Expenses" would be 1.13%, 1.88%, and 1.88% for class 529A, 529B and 529C shares, respectively. The only fees and charges a 529 participant will incur are an annual maintenance fee, sales charges and expenses of the fund, and miscellaneous other fees which may be charged in connection with the administration of the participant's account. See the program description and materials available from your financial representative for details.

(3) MFS has contractually agreed to waive its right to receive 0.05% of the management fee annually. In addition, as noted above, the fund's distributor, MFS Fund Distributors, Inc., has contractually agreed to waive 0.10% of the class 529A service fee. These contractual fee arrangements will remain in effect until at least September 1, 2002, absent an earlier modification approved by the board of trustees which oversees the fund.

Example of Expenses

These examples are intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The examples assume that:

o You invest $10,000 in the fund for the time periods indicated and you redeem your shares at the end of the time periods;

o Your investment has a 5% return each year and dividends and other distributions are reinvested; and

o The fund's operating expenses remain the same, except that the fund's total operating expenses are assumed to be the fund's "Net Expenses" through September 1, 2002, and the fund's "Total Annual Operating Expenses" for subsequent years (see "Expense Table").

Although your actual costs may be higher or lower, under these assumptions your costs would be:

     Share Class                                     Year 1         Year 3
     Class 529A shares                                $365           $640
     Class 529B shares
         Assuming redemption at end of period         $594           $910
         Assuming no redemption                       $194           $610

     Class 529C shares

         Assuming redemption at end of period         $294           $610
         Assuming no redemption                       $194           $610


3.   MANAGEMENT OF THE FUND

Program Manager(s)

The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFS Fund Distributors, Inc. ("MFD") pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to a tuition program to which MFD provides administrative services ("529 assets"). The current fee has been established at 0.25% annually of the average net assets of the fund's 529 share classes. The fee may only be increased with the approval of the board of trustees that oversees the fund.


The services provided by MFD include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Code and other regulatory requirements.

4. DESCRIPTION OF SHARE CLASSES

The description of the fund's class A, B and C shares in the Prospectus applies equally to the corresponding class 529A, 529B and 529C shares. For example, the description of sales charges and the calculation of the CDSC is identical for the fund's class A, B and C shares and the corresponding class 529A, 529B and 529C shares.

Waivers of Sales Charges

Sales charge waivers that apply to the fund's class A, B and C shares apply equally to the corresponding class 529A, 529B and 529C shares, and are described in the fund's Statement of Additional Information (SAI), which is available upon request (see back page of the Prospectus for information on how to obtain a copy of the SAI). In addition:

o any CDSC with respect to the 529 share classes will be waived where the redemption proceeds are used to pay for qualified higher education expenses, which may include tuition, fees, books, supplies, equipment and room and board (see the program description for further information on qualified higher education expenses); however, the CDSC will not be waived for redemptions where the proceeds are transferred or rolled over to another tuition program; and

o all sales charges will be waived with respect to shares purchased through an employer sponsored plan, pursuant to guidelines created by MFD from time to time.

Distribution and Service Fees

The fund has adopted a plan under Rule 12b-1 that permits it to pay marketing and other fees to support the sale and distribution of class 529A, 529B and 529C shares, and the services provided to you by your financial adviser. These annual distribution and service fees may equal up to 0.50% (0.25% distribution fee and 0.25% service fee) for class 529A shares and 1.00% (0.75% distribution fee and 0.25% service fee) for each of class 529B and 529C shares, and are paid out of the assets of these classes. Over time, these fees will increase the cost of your shares and may cost you more than paying other types of sale charges. A portion of the class 529A distribution fee equal to 0.15% is not currently in effect and may be imposed only with the approval of the board of trustees which oversees the fund. In addition, a portion of the class 529A service fee equal to 0.10% is being waived by the fund's distributor, MFS Fund Distributors, Inc. Except in the case of the 0.25% per annum class 529B service fee paid by the fund upon the sale of class 529B shares in the first year, the class 529B service fee is currently set at 0.15% per annum and may be increased to 0.25% per annum on such date as the trustees of the fund may determine.

5. HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES

The description of how to purchase, exchange and redeem class A, B and C shares, together with the description of other related considerations, in the Prospectus applies equally to the corresponding class 529A, 529B and 529C shares, with a few exceptions noted below.

How to Purchase Shares

The Code and tuition programs impose a maximum total contribution limitation for designated beneficiaries on behalf of whom assets under tuition programs are held, which may result in a limitation on your ability to purchase the fund's 529 share classes. Please see the program description for details concerning the maximum contribution limitation and its application.

An account owner of a newly established account under a tuition program in which the designated beneficiary is age 12 or older will not be entitled to purchase class 529B shares.


Additional restrictions may apply and are described in the program description.

How to Exchange Shares

Your ability to exchange your class 529A, 529B or 529C shares of the fund for corresponding class 529A, 529B and 529C shares of other MFS funds may be limited under Section 529 of the Code and the tuition program through which your investment in the MFS funds is made. Please see the program description for details.

How to Redeem Shares

If you redeem your class 529A, 529B or 529C shares and use the proceeds for non-qualified higher education expenses or other non-qualified purposes, taxes and penalties may apply. Please see the program description and the discussion below under the caption "Tax Considerations" for details.

6. INVESTOR SERVICES AND PROGRAMS

The description of investor services and programs in the Prospectus applies to class 529A, 529B and 529C shares, and references to class A, B and C shares in that discussion apply as well to the corresponding class 529A, 529B and 529C shares, with the exception noted below.

Distribution Options

Distributions on the 529 share classes will automatically be reinvested in additional shares. Account owners do not have the option of receiving distributions in cash.

7. OTHER INFORMATION

The description under "Other Information" in the Prospectus applies equally to class 529A, 529B and 529C shares. In addition, because the account owner may invest in the fund's class 529A, 529B and 529C shares indirectly through a tuition program, the account owner may not technically be a shareholder of the fund (rather, a trust or other vehicle established by the state or eligible educational institution through which the investment is made would be the fund's shareholder of record). Therefore, with respect to investments through certain tuition programs, the account owner may not have voting rights in the fund's shares or may only be entitled to vote if the tuition program through which the fund shares are held passes through the voting rights to the account owner. Please see the program description for details.

Tax Considerations

In addition to the tax considerations discussed in the fund's Prospectus and SAI, please note the following tax considerations that apply specifically to the ownership of the fund's 529 share classes.

The fund is an investment option under one or more tuition programs designed to qualify under Section 529 of the Code so that earnings on investments are not subject to federal income tax (to either a contributor to the tuition program or a designated beneficiary) until the earnings are withdrawn. Withdrawals of earnings that are used to pay "qualified higher education expenses" are tax-free for federal income tax purposes for tax years beginning on or before December 31, 2010. State and local taxes may still apply.

Withdrawals of earnings that are not used for the designated beneficiary's qualified higher education expenses generally are subject not only to federal income tax but also to a 10% penalty tax (unless such amounts are transferred within sixty (60) days to another tuition program for the same designated beneficiary or another designated beneficiary who is a member of the family of the designated beneficiary with respect to which the distribution was made and certain other conditions are satisfied). The 10% penalty tax will not apply to withdrawals made under certain circumstances, including certain withdrawals made after the designated beneficiary dies or becomes disabled. Withdrawals


attributable to contributions to the tuition program (including the portion of any rollover from another tuition program that is attributable to contributions to that program) are not subject to tax.

The foregoing is only a brief summary of some of the important federal income tax considerations relating to investments in the fund under the tuition programs; you will find more information in the program description. You are urged to consult your own tax adviser for information about the federal estate and gift and the state and local tax consequences of, and impact of your personal financial situation on, an investment in the fund's 529 share classes.

8. FINANCIAL HIGHLIGHTS

Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not have financial highlights to report.

Class 529A, 529B and 529C shares are only offered in conjunction with qualified tuition programs (tuition programs) established in accordance with Section 529 of the Internal Revenue Code (Code). Contributions to these tuition programs may be invested in the fund's class 529A, 529B or 529C shares and certain other MFS funds offering these share classes. Earnings on investments in the fund made through such tuition programs may receive favorable tax treatment under the Code, as described further under the caption "Tax Considerations" below. For information on policies, services and restrictions which apply to your account with the tuition program through which your investment in the fund is made, please refer to the description of the tuition program available from your financial representative (the program description).

1. RISK RETURN SUMMARY

Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not yet have a performance record to report.

Total Annual Fund Operating Expenses(2)....          1.23%              1.88%             1.88%


(1) The fund adopted a distribution plan under Rule 12b-1 that permits it to pay marketing and other fees to support the sale and distribution of class 529A, 529B and 529C shares and the services provided to you by your financial adviser (referred to as distribution and service fees). The maximum distribution and service fees under the plan are 0.50% annually for class 529A shares and 1.00% annually for class 529B and 529C shares.


The remaining 0.15% class 529A distribution fee may be imposed only with the approval of the board of trustees which oversees the fund.

(2) "Other Expenses" are estimated for the fund's current fiscal year, and include the program management fee described below under "Management of the Fund." The fund has an expense offset arrangement which reduces the fund's custodian fee based upon the amount of cash maintained by the fund with its custodian and dividend disbursing agent. The fund may also enter into other such arrangements and directed brokerage arrangements (which would also have the effect of reducing the fund's expenses). Any such fee reductions are not reflected in the table. Had these expense reductions been taken into account, "Total Annual Fund Operating Expenses" would be 1.21%, 1.86%, and 1.86% for class 529A, 529B and 529C shares, respectively. The only fees and charges a 529 participant will incur are an annual maintenance fee, sales charges and expenses of the fund, and miscellaneous other fees which may be charged in connection with the administration of the participant's account. See the program description and materials available from your financial representative for details.

Example of Expenses

These examples are intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The examples assume that:

o You invest $10,000 in the fund for the time periods indicated and you redeem your shares at the end of the time periods;

o Your investment has a 5% return each year and dividends and other distributions are reinvested; and

o The fund's operating expenses remain the same.

Although your actual costs may be higher or lower, under these assumptions your costs would be:

     Share Class                                 Year 1         Year 3
     Class 529A shares                            $594           $847
     Class 529B shares
         Assuming redemption at end of period     $591           $891

3.   MANAGEMENT OF THE FUND

Program Manager(s)

The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFS Fund Distributors, Inc. ("MFD") pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to a tuition program to which MFD provides administrative services ("529 assets").

4. DESCRIPTION OF SHARE CLASSES

Over time, these fees will increase the cost of your shares and may cost you more than paying other types of sale charges.

5. HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES

The description of how to purchase, exchange and redeem class A, B and C shares, together with the description of other related considerations, in the Prospectus applies equally to the corresponding class 529A, 529B and 529C shares, with a few exceptions noted below.

How to Purchase Shares

The Code and tuition programs impose a maximum total contribution limitation for designated beneficiaries on behalf of whom assets under tuition programs are held, which may result in a limitation on your ability to purchase the fund's 529 share classes. Please see the program description for details concerning the maximum contribution limitation and its application.

An account owner of a newly established account under a tuition program in which the designated beneficiary is age 12 or older will not be entitled to purchase class 529B shares. Additional restrictions may apply and are described in the program description.

Your ability to exchange your class 529A, 529B or 529C shares of the fund for corresponding class 529A, 529B and 529C shares of other MFS funds may be limited under Section 529 of the Code and the tuition program through which your investment in the MFS funds is made. Please see the program description for details.

How to Redeem Shares

If you redeem your class 529A, 529B or 529C shares and use the proceeds for non-qualified higher education expenses or other non-qualified purposes, taxes and penalties may apply. Please see the program description and the discussion below under the caption "Tax Considerations" for details.

Distributions on the 529 share classes will automatically be reinvested in additional shares. Account owners do not have the option of receiving distributions in cash.

7. OTHER INFORMATION

The description under "Other Information" in the Prospectus applies equally to class 529A, 529B and 529C shares. In addition, because the account owner may invest in the fund's class 529A, 529B and 529C shares indirectly through a tuition program, the account owner may not technically be a shareholder of the fund (rather, a trust or other vehicle established by the state or eligible educational institution through which the investment is made would be the fund's shareholder of record). Therefore, with respect to investments through certain tuition programs, the account owner may not have voting rights in the fund's shares or may only be entitled to vote if the tuition program through which the fund shares are held passes through the voting rights to the account owner. Please see the program description for details.

Tax Considerations

In addition to the tax considerations discussed in the fund's Prospectus and SAI, please note the following tax considerations that apply specifically to the ownership of the fund's 529 share classes.

The fund is an investment option under one or more tuition programs designed to qualify under Section 529 of the Code so that earnings on investments are not subject to federal income tax (to either a contributor to the tuition program or a designated beneficiary) until the earnings are withdrawn. Withdrawals of earnings that are used to pay "qualified higher education expenses" are tax-free for federal income tax purposes for tax years beginning on or before December 31, 2010. State and local taxes may still apply.

Withdrawals of earnings that are not used for the designated beneficiary's qualified higher education expenses generally are subject not only to federal income tax but also to a 10% penalty tax (unless such amounts are transferred within sixty (60) days to another tuition program for the same designated beneficiary or another designated beneficiary who is a member of the family of the designated beneficiary with respect to which the distribution was made and certain other conditions are satisfied). . The 10% penalty tax will not apply to withdrawals made under certain circumstances, including certain withdrawals made after the designated beneficiary dies or becomes disabled. Withdrawals attributable to contributions to the tuition program (including the portion of any rollover from another tuition program that is attributable to contributions to that program) are not subject to tax.

The foregoing is only a brief summary of some of the important federal income tax considerations relating to investments in the fund under the tuition programs; you will find more information in the program description. You are urged to consult your own tax adviser for information about the federal estate and gift and the state and local tax consequences of, and impact of your personal financial situation on, an investment in the fund's 529 share classes.

8. FINANCIAL HIGHLIGHTS

Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not have financial highlights to report.

MFS(R) RESEARCH BOND FUND

Supplement dated August 1, 2002 to the Current Prospectus

This Supplement describes the fund's class 529A, 529B and 529C shares, and it supplements certain information in the fund's Prospectus dated September 1, 2001. The caption headings used in this Supplement correspond with the caption headings used in the Prospectus.

Class 529A, 529B and 529C shares are only offered in conjunction with qualified tuition programs (tuition programs) established in accordance with Section 529 of the Internal Revenue Code (Code). Contributions to these tuition programs may be invested in the fund's class 529A, 529B or 529C shares and certain other MFS funds offering these share classes. Earnings on investments in the fund made through such tuition programs may receive favorable tax treatment under the Code, as described further under the caption "Tax Considerations" below. For information on policies, services and restrictions which apply to your account with the tuition program through which your investment in the fund is made, please refer to the description of the tuition program available from your financial representative (the program description).

1. RISK RETURN SUMMARY

Performance Table. The "Performance Table" is intended to indicate some of the risks of investing in the fund by showing changes in the fund's performance over time. Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not yet have a performance record to report.

2. EXPENSE SUMMARY

    Fee Waiver(3)..........................         (4.56)%            (4.46)%           (4.46)%
                                                    -------            -------           -------
    Net Expenses(2)........................          1.07%              1.82%             1.82%


(1) The fund adopted a distribution plan under Rule 12b-1 that permits it to pay marketing and other fees to support the sale and distribution of class 529A, 529B and 529C shares and the services provided to you by your


financial adviser (referred to as distribution and service fees). The maximum distribution and service fees under the plan are 0.50% annually for class 529A shares and 1.00% annually for class 529B and 529C shares. The fund's distributor, MFS Fund Distributors, Inc., has contractually agreed to waive 0.10% annually of the fund's class 529A service fee (see footnote
(3) below). The remaining 0.15% class 529A distribution fee may be imposed only with the approval of the board of trustees which oversees the fund.

(2) "Other Expenses" are estimated for the fund's current fiscal year, and include the program management fee described below under "Management of the Fund." The fund has an expense offset arrangement which reduces the fund's custodian fee based upon the amount of cash maintained by the fund with its custodian and dividend disbursing agent. The fund may also enter into other such arrangements and directed brokerage arrangements (which would also have the effect of reducing the fund's expenses). Any such fee reductions are not reflected in the table. Had these expense reductions been taken into account, "Total Annual Fund Operating Expenses" would be 1.05%, 1.80%, and 1.80% for class 529A, 529B and 529C shares, respectively. The only fees and charges a 529 participant will incur are an annual maintenance fee, sales charges and expenses of the fund, and miscellaneous other fees which may be charged in connection with the administration of the participant's account. See the program description and materials available from your financial representative for details.

(3) MFS has contractually agreed to waive its right to receive 0.15% of the management fee annually and to bear the fund's expenses such that "Other Expenses" (after taking into account the expense offset arrangement described above) do not exceed 0.45% annually for class 529A, 529B and 529C shares. In addition, as noted above, the fund's distributor, MFS Fund Distributors, Inc., has contractually agreed to waive 0.10% of the class 529A service fee. These contractual arrangements will continue until at least September 1, 2002, absent an earlier modification approved by the board of trustees which oversees the fund.

Example of Expenses

These examples are intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The examples assume that:

o You invest $10,000 in the fund for the time periods indicated and you redeem your shares at the end of the time periods;

o Your investment has a 5% return each year and dividends and other distributions are reinvested; and

o The fund's operating expenses remain the same, except that the fund's total operating expenses are assumed to be the fund's "Net Expenses" through September 1, 2002, and the fund's "Total Annual Operating Expenses" for subsequent years (see "Expense Table").

Although your actual costs may be higher or lower, under these assumptions your costs would be:

     Share Class                                Year 1         Year 3
     Class 529A shares                           $579          $1,687
     Class 529B shares
         Assuming redemption at end of period    $585          $1,764
         Assuming no redemption                  $185          $1,464

     Class 529C shares

         Assuming redemption at end of period    $285          $1,464
         Assuming no redemption                  $185          $1,464


3.   MANAGEMENT OF THE FUND

Program Manager(s)

The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFS Fund Distributors, Inc. ("MFD") pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to a tuition program to which MFD provides administrative services ("529 assets"). The current fee has been established at 0.25% annually of the average net assets of the fund's 529 share classes. The fee may only be increased with the approval of the board of trustees that oversees the fund.


The services provided by MFD include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Code and other regulatory requirements.

4. DESCRIPTION OF SHARE CLASSES

The description of the fund's class A, B and C shares in the Prospectus applies equally to the corresponding class 529A, 529B and 529C shares. For example, the description of sales charges and the calculation of the CDSC is identical for the fund's class A, B and C shares and the corresponding class 529A, 529B and 529C shares.

Waivers of Sales Charges

Sales charge waivers that apply to the fund's class A, B and C shares apply equally to the corresponding class 529A, 529B and 529C shares, and are described in the fund's Statement of Additional Information (SAI), which is available upon request (see back page of the Prospectus for information on how to obtain a copy of the SAI). In addition:

o any CDSC with respect to the 529 share classes will be waived where the redemption proceeds are used to pay for qualified higher education expenses, which may include tuition, fees, books, supplies, equipment and room and board (see the program description for further information on qualified higher education expenses); however, the CDSC will not be waived for redemptions where the proceeds are transferred or rolled over to another tuition program; and

o all sales charges will be waived with respect to shares purchased through an employer sponsored plan, pursuant to guidelines created by MFD from time to time.

Distribution and Service Fees

The fund has adopted a plan under Rule 12b-1 that permits it to pay marketing and other fees to support the sale and distribution of class 529A, 529B and 529C shares, and the services provided to you by your financial adviser. These annual distribution and service fees may equal up to 0.50% (0.25% distribution fee and 0.25% service fee) for class 529A shares and 1.00% (0.75% distribution fee and 0.25% service fee) for each of class 529B and 529C shares, and are paid out of the assets of these classes. Over time, these fees will increase the cost of your shares and may cost you more than paying other types of sale charges. A portion of the class 529A distribution fee equal to 0.15% is not currently in effect and may be imposed only with the approval of the board of trustees which oversees the fund. In addition, a portion of the class 529A service fee equal to 0.10% is being waived by MFS Fund Distributors, Inc.

5. HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES

The description of how to purchase, exchange and redeem class A, B and C shares, together with the description of other related considerations, in the Prospectus applies equally to the corresponding class 529A, 529B and 529C shares, with a few exceptions noted below.

How to Purchase Shares

The Code and tuition programs impose a maximum total contribution limitation for designated beneficiaries on behalf of whom assets under tuition programs are held, which may result in a limitation on your ability to purchase the fund's 529 share classes. Please see the program description for details concerning the maximum contribution limitation and its application.

An account owner of a newly established account under a tuition program in which the designated beneficiary is age 12 or older will not be entitled to purchase class 529B shares. Additional restrictions may apply and are described in the program description.


How to Exchange Shares

Your ability to exchange your class 529A, 529B or 529C shares of the fund for corresponding class 529A, 529B and 529C shares of other MFS funds may be limited under Section 529 of the Code and the tuition program through which your investment in the MFS funds is made. Please see the program description for details.

How to Redeem Shares

If you redeem your class 529A, 529B or 529C shares and use the proceeds for non-qualified higher education expenses or other non-qualified purposes, taxes and penalties may apply. Please see the program description and the discussion below under the caption "Tax Considerations" for details.

6. INVESTOR SERVICES AND PROGRAMS

The description of investor services and programs in the Prospectus applies to class 529A, 529B and 529C shares, and references to class A, B and C shares in that discussion apply as well to the corresponding class 529A, 529B and 529C shares, with the exception noted below.

Distribution Options

Distributions on the 529 share classes will automatically be reinvested in additional shares. Account owners do not have the option of receiving distributions in cash.

7. OTHER INFORMATION

The description under "Other Information" in the Prospectus applies equally to class 529A, 529B and 529C shares. In addition, because the account owner may invest in the fund's class 529A, 529B and 529C shares indirectly through a tuition program, the account owner may not technically be a shareholder of the fund (rather, a trust or other vehicle established by the state or eligible educational institution through which the investment is made would be the fund's shareholder of record). Therefore, with respect to investments through certain tuition programs, the account owner may not have voting rights in the fund's shares or may only be entitled to vote if the tuition program through which the fund shares are held passes through the voting rights to the account owner. Please see the program description for details.

Tax Considerations

In addition to the tax considerations discussed in the fund's Prospectus and SAI, please note the following tax considerations that apply specifically to the ownership of the fund's 529 share classes.

The fund is an investment option under one or more tuition programs designed to qualify under Section 529 of the Code so that earnings on investments are not subject to federal income tax (to either a contributor to the tuition program or a designated beneficiary) until the earnings are withdrawn. Withdrawals of earnings that are used to pay "qualified higher education expenses" are tax-free for federal income tax purposes for tax years beginning on or before December 31, 2010. State and local taxes may still apply.

Withdrawals of earnings that are not used for the designated beneficiary's qualified higher education expenses generally are subject not only to federal income tax but also to a 10% penalty tax (unless such amounts are transferred within sixty (60) days to another tuition program for the same designated beneficiary or another designated beneficiary who is a member of the family of the designated beneficiary with respect to which the distribution was made and certain other conditions are satisfied). The 10% penalty tax will not apply to withdrawals made under certain circumstances, including certain withdrawals made after the designated beneficiary dies or becomes disabled. Withdrawals attributable to contributions to the tuition program (including the portion of any rollover from another tuition program that is attributable to contributions to that program) are not subject to tax.


The foregoing is only a brief summary of some of the important federal income tax considerations relating to investments in the fund under the tuition programs; you will find more information in the program description. You are urged to consult your own tax adviser for information about the federal estate and gift and the state and local tax consequences of, and impact of your personal financial situation on, an investment in the fund's 529 share classes.

8. FINANCIAL HIGHLIGHTS

Because class 529A, 529B and 529C shares are being initially offered for sale on August 1, 2002, these share classes do not have financial highlights to report.

TRUSTEES

Section 2.1. Number of Trustees. The number of Trustees shall be such number as shall be fixed from time to time by a majority of the Trustees, provided, however, that the number of Trustees shall in no event be less than three nor more than 15.

Section 2.2. Term of Office of Trustees. A Trustee may be elected either by the Shareholders of the Trust or, as provided in the Declaration and subject to the limitations of the 1940 Act, by the Trustees. Subject to all applicable provisions of the 1940 Act, a Trustee shall hold office during the lifetime of this Trust and until its termination as hereinafter provided or, if sooner, until his or her death or the election and qualification of his or her successor; except that:

(a) any Trustee may resign his or her trust (without need for prior or subsequent accounting) by an instrument in writing signed by that Trustee and delivered to the Trust, which shall take effect upon such delivery or upon such later date as is specified therein;


4

(b) any Trustee may be removed at any time, with or without cause, by written instrument signed by at least three-quarters of the Trustees, specifying the date when such removal shall become effective;

(c) any Trustee who has attained a mandatory retirement age established pursuant to any written policy adopted from time to time by at least two-thirds of the Trustees shall, automatically and without action of such Trustee or the remaining Trustees, be deemed to have retired in accordance with the terms of such policy, effective as of the date determined in accordance with such policy;

(d) any Trustee who has served to the end of his or her term of office established pursuant to any written policy adopted from time to time by at least two-thirds of the Trustees shall, automatically and without action of such Trustee or the remaining Trustees, be deemed to have retired in accordance with the terms of such policy, effective as of the date determined in accordance with such policy; and

(e) a Trustee may be removed at any meeting of Shareholders by a vote of Shares representing two-thirds of the voting power of the outstanding Shares of the Trust.

Upon the resignation, retirement or removal of a Trustee, or his or her otherwise ceasing to be a Trustee, that individual shall execute and deliver such documents as the remaining Trustees shall require for the purpose of conveying to the Trust or the remaining Trustees any Trust Property held in the name of the resigning, retiring or removed Trustee. Upon the incapacity or death of any Trustee, that Trustee's legal representative shall execute and deliver on his or her behalf such documents as the remaining Trustees shall require as provided in the preceding sentence.

Except to the extent expressly provided in a written agreement to which the Trust is a party or in a written policy adopted by the Trustees, no resigning or removed Trustee shall have any right to any compensation for any period following his or her resignation or removal, or any right to damages on account of such removal.

Section 2.3. Resignation and Appointment of Trustees. In case of the declination, death, resignation, retirement or removal of any of the Trustees, or in case a vacancy shall, by reason of an increase in number of Trustees, or for any other reason, exist, a majority of the remaining Trustees may fill such vacancy by appointing such other individual as they in their discretion shall see fit. Any such appointment shall not become effective, however, until the person appointed shall have accepted in writing such appointment and agreed in writing to be bound by the terms of the Declaration. An appointment of a Trustee may be made by the Trustees then in office in anticipation of a


5

vacancy to occur by reason of retirement, resignation, removal or increase in number of Trustees effective at a later date, provided that said appointment shall become effective only at or after the effective date of said retirement, resignation, removal or increase in number of Trustees. The power of appointment is subject to all applicable provisions of the 1940 Act.

Section 2.4. Vacancies. The death, declination, resignation, retirement, removal or incapacity of the Trustees, or any of them, shall not operate to annul the Trust or to revoke any existing agency created pursuant to the terms of the Declaration. Whenever a vacancy in the number of Trustees shall occur, until such vacancy is filled as provided in Section 2.3, or while any Trustee is incapacitated, the other Trustees in office, regardless of their number, shall have all the powers granted to the Trustees and shall discharge all the duties imposed upon the Trustees by the Declaration, and only such other Trustees shall be counted for the purposes of the existence of a quorum or the taking of any action to be taken by the Trustees. A written instrument certifying the existence of such vacancy or incapacity signed by a majority of the Trustees shall be conclusive evidence of the existence thereof.

Section 2.5. Delegation of Power to Other Trustees. Subject to requirements imposed by the 1940 Act and other applicable law, any Trustee may, by power of attorney, delegate his power for a period not exceeding six months at any one time to any other Trustee or Trustees; provided that in no case shall fewer than two Trustees personally exercise the powers granted to the Trustees under the Declaration except as otherwise expressly provided herein.

ARTICLE III

POWERS OF TRUSTEES

Section 3.1. General. Subject to the provisions of the Declaration, the Trustees shall have exclusive and absolute control over the Trust Property and over the business of the Trust to the same extent as if the Trustees were the sole owners of the Trust Property and business in their own right, but with such powers of delegation as may be permitted by the Declaration. The Trustees shall have power to conduct the business of the Trust and carry on its operations in any and all of its branches and maintain offices both within and without The Commonwealth of Massachusetts, in any and all states of the United States of America, in the District of Columbia, and in any and all commonwealths, territories, dependencies, colonies, possessions, agencies or instrumentalities of the United States of America and of foreign governments, and to do all such other things and execute all such instruments as the Trustees deem necessary, proper or desirable in order to promote the interests of the Trust although such things are not herein specifically mentioned. Any determination as to what is in the interests of the Trust made by the Trustees


6

in good faith shall be conclusive. In construing the provisions of the Declaration, the presumption shall be in favor of a grant of power to the Trustees.

The enumeration of any specific power herein shall not be construed as limiting the aforesaid power or any other power of the Trustees hereunder. Such powers of the Trustees may be exercised without order of or resort to any court.

Section 3.2. Investments. (a) The Trustees shall have the power:

(i) to conduct, operate and carry on the business of an investment company;

(ii) to subscribe for, invest in, reinvest in, purchase or otherwise acquire, own, hold, pledge, sell, assign, transfer, exchange, distribute, lend or otherwise deal in or dispose of securities of every nature and kind, U.S. and foreign currencies, any form of gold or other precious metal, commodity contracts, any form of option contract, contracts for the future acquisition or delivery of fixed income or other securities, derivative instruments of every kind, "when-issued" or standby contracts, and all types of obligations or financial instruments, including, without limitation, all types of bonds, debentures, stocks, negotiable or non-negotiable instruments, obligations, evidences of indebtedness, certificates of deposit or indebtedness, commercial paper, repurchase agreements, bankers' acceptances, and other securities of any kind, issued, created, guaranteed or sponsored by any and all Persons, including, without limitation,

(A) states, territories and possessions of the United States and the District of Columbia and any political subdivision, agency or instrumentality of any such Person,

(B) the U.S. Government, any foreign government, or any political subdivision or any agency or instrumentality of the U.S. Government or any foreign government,

(C) any international instrumentality,

(D) any bank or savings institution, or

(E) any corporation or organization organized under the laws of the United States or of any state, territory or possession thereof, or under any foreign law;

to retain Trust assets in cash and from time to time to change the investments in which the assets of the Trust are invested; and to exercise any and all rights,


7

powers and privileges of ownership or interest in respect of any and all such investments of every kind and description, including, without limitation, the right to consent and otherwise act with respect thereto, with power to designate one or more Persons to exercise any of said rights, powers and privileges in respect of any of said investments; and

(iii) to carry on any other business in connection with or incidental to any of the foregoing powers, to do everything necessary, proper or desirable for the accomplishment of any purpose or the attainment of any object or the furtherance of any power hereinbefore set forth, and to do every other act or thing incidental or appurtenant to or connected with the aforesaid purposes, objects or powers.

(b) The Trustees shall not be limited to investing in securities or obligations maturing before the possible termination of the Trust, nor shall the Trustees be limited by any law limiting the investments which may be made by fiduciaries.

(c) Notwithstanding any other provision of the Declaration to the contrary, the Trustees shall have the power in their discretion without any requirement of approval by Shareholders to either invest all or a portion of the Trust Property of the Trust and each series of the Trust, or sell all or a portion of such Trust Property and invest the proceeds of such sales, in one or more other investment companies to the extent not prohibited by the 1940 Act.

Section 3.3. Legal Title. Legal title to all Trust Property shall be vested in the Trustees as joint tenants except that the Trustees shall have power to cause legal title to any Trust Property to be held by or in the name of one or more of the Trustees, or in the name of the Trust, or in the name of any other Person or nominee, on such terms as the Trustees may determine. The right, title and interest of the Trustees in the Trust Property shall vest automatically in each person who may hereafter become a Trustee. Upon the resignation, retirement, removal or death of a Trustee, such Trustee shall automatically cease to have any right, title or interest in any of the Trust Property, and the right, title and interest of such Trustee in the Trust Property shall vest automatically in the remaining Trustees. Such vesting and cessation of title shall be effective whether or not conveyancing documents have been executed and delivered.

Section 3.4. Issuance and Repurchase of Securities. The Trustees shall have the power to issue, sell, repurchase, redeem, retire, cancel, acquire, hold, resell, reissue, dispose of, transfer, and otherwise deal in Shares and, subject to the provisions set forth in Articles VII, VIII and IX and Section 6.9 hereof, to apply to any such repurchase, redemption, retirement, cancellation or acquisition of Shares any funds of the Trust or other Trust Property, whether capital or surplus or otherwise.


8

Section 3.5. Borrowing Money; Lending Trust Property. The Trustees shall have power to borrow money or otherwise obtain credit and to secure the same by mortgaging, pledging or otherwise subjecting as security the Trust Property, to endorse, guarantee, or undertake the performance of any obligation, contract or engagement of any other Person and to lend Trust Property.

Section 3.6. Delegation. The Trustees shall have power to delegate from time to time to such of their number or to officers, employees, any Investment Adviser, Distributor, custodian, agent or independent contractor of the Trust the doing of such things and the execution of such instruments either in the name of the Trust or the names of the Trustees or otherwise as the Trustees may deem appropriate or expedient.

Section 3.7. Collection and Payment. Subject to Section 6.9 hereof, the Trustees shall have power to collect all property due to the Trust; to pay all claims, including taxes, against the Trust Property; to prosecute, defend, compromise or abandon any claims relating to the Trust Property; to foreclose any security interest securing any obligations, by virtue of which any property is owed to the Trust; and to enter into releases, agreements and other instruments.

Section 3.8. Expenses. Subject to Section 6.9 hereof, the Trustees shall have the power to incur and pay any expenses which in the opinion of the Trustees are necessary or incidental to carry out any of the purposes of the Declaration, and to pay reasonable compensation from the funds of the Trust to themselves as Trustees. The Trustees shall fix the compensation of all officers, employees, Trustees and Trustees Emeritus.

Section 3.9. Manner of Acting; By-Laws. Except as otherwise provided herein, in the 1940 Act or in the By-Laws, any action to be taken by the Trustees may be taken by a majority of the Trustees present at a meeting of Trustees at which a quorum is present, including any meeting held by means of a conference telephone circuit or similar communications equipment by means of which all persons participating in the meeting can hear each other, or by written consents of two-thirds of the Trustees. The Trustees may adopt By-Laws not inconsistent with the Declaration to provide for the conduct of the business of the Trust and may amend or repeal such By-Laws to the extent permitted therein at any time.

Section 3.10. Miscellaneous Powers. Without limiting the foregoing, the Trustees shall have the power to:

9

(b) enter into joint ventures, partnerships and any other combinations or associations;

(e) establish pension, profit-sharing, Share purchase, deferred compensation, and other retirement, incentive and benefit plans for any Trustees, officers, employees or agents of the Trust;

ARTICLE V

LIMITATIONS OF LIABILITY OF SHAREHOLDERS,
TRUSTEES AND OTHERS

Section 5.1. No Personal Liability of Shareholders. No Shareholder or former Shareholder shall be subject to any personal liability whatsoever to any Person in connection with Trust Property or the acts, obligations or affairs of the Trust solely by reason of being or having been a Shareholder. The Trust shall indemnify and hold each Shareholder and former Shareholder harmless from and against all claims and liabilities to which such Shareholder may become subject solely by reason of his or her being or having been a Shareholder (other than taxes payable by virtue of owning Shares), and shall reimburse such Shareholder for all legal and other expenses reasonably incurred by him in connection with any such claim or liability. The rights accruing to a Shareholder or former Shareholder under this Section 5.1 shall not exclude any other right to which such Shareholder may be lawfully entitled, nor shall anything herein contained restrict the right of the Trust to indemnify or reimburse a Shareholder or former Shareholder in any appropriate situation even though not specifically provided herein. The Trust shall, upon request by a Shareholder or former Shareholder, assume the defense of any claim made against such Shareholder for any act or obligation of the Trust and satisfy any judgment thereon from the assets of the Trust. Notwithstanding


12

any other provision of the Declaration to the contrary, no Trust Property shall be used to indemnify or reimburse any Shareholder or former Shareholder of any Shares of any series other than Trust Property allocated or belonging to such series.

Section 5.2. Limitation of Liability of Trustees and Others. (a) No Trustee, Trustee Emeritus, officer, employee or agent of the Trust shall be subject to any liability whatsoever to any Person in connection with Trust Property or the affairs of the Trust, and no Trustee or Trustee Emeritus shall be responsible or liable in any event for any neglect or wrongdoing of any officer, employee or agent of the Trust or for the act of omission of any other Trustee or Trustee Emeritus. Notwithstanding anything to the contrary in this
Section 5.2(a) or otherwise, nothing in the Declaration shall protect any Trustee, Trustee Emeritus, officer, employee or agent of the Trust against any liability to the Trust or its Shareholders to which he, she or it would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his, her or its office or position with or on behalf of the Trust.

(b) All persons extending credit to, contracting with or having claim against the Trust or any series or class shall look solely to the assets of the Trust or to the assets of that series or class for payment under such credit, contract or claim; and neither any Trustee or Trustee Emeritus, nor any of the Trust's officers, employees or agents, whether past, present or future, shall be personally liable therefor.

Section 5.3. Mandatory Indemnification. (a) Subject to the exceptions and limitations contained in paragraph (b) below:

(i) every person who is or has been a Trustee, Trustee Emeritus or officer of the Trust (hereinafter referred to as a "Covered Person") shall be indemnified by the Trust against all liability and against all expenses reasonably incurred or paid by him or her in connection with any claim, action, suit or proceeding in which that individual becomes involved as a party or otherwise by virtue of being or having been a Trustee, Trustee Emeritus or officer and against amounts paid or incurred by that individual in the settlement thereof;

(ii) the words "claim," "action," "suit" or "proceeding" shall apply to all claims, actions, suits or proceedings (civil, criminal, administrative or other, including appeals), actual or threatened; and the words "liability" and "expenses" shall include, without limitation, attorneys' fees, costs, judgments, amounts paid in settlement or compromise, fines, penalties and other liabilities.


13

(b) No indemnification shall be provided hereunder to a Covered Person:

(i) against any liability to the Trust or the Shareholders by reason of a final adjudication by the court or other body before which the proceeding was brought that the Covered Person engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of that individual's office;

(ii) with respect to any matter as to which the Covered Person shall have been finally adjudicated not to have acted in good faith in the reasonable belief that that individual's action was in the best interest of the Trust; or

(iii) in the event of a settlement involving a payment by a Trustee, Trustee Emeritus or officer or other disposition not involving a final adjudication as provided in paragraph (b)(i) or (b)(ii) above resulting in a payment by a Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of that individual's office by the court or other body approving the settlement or other disposition or by a reasonable determination, based upon a review of readily available facts (as opposed to a full trial-type inquiry) that that individual did not engage in such conduct:

(A) by vote of a majority of the Disinterested Trustees (as defined below) acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter); or

(B) by written opinion of (i) the then-current legal counsel to the Trustees who are not Interested Persons of the Trust or (ii) other legal counsel chosen by a majority of the Disinterested Trustees (or if there are no Disinterested Trustees with respect to the matter in question, by a majority of the Trustees who are not Interested Persons of the Trust) and determined by them in their reasonable judgment to be independent.

(c) The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such person. Nothing contained herein shall limit the Trust from entering into other insurance arrangements or affect any rights to indemnification to which Trust personnel, including Covered Persons, may be entitled by contract or otherwise under law.


14

(d) Expenses of preparation and presentation of a defense to any claim, action, suit, or proceeding of the character described in paragraph (a) of this
Section 5.3 shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the Covered Person to repay such amount if it is ultimately determined that the Covered Person is not entitled to indemnification under this Section 5.3, provided that either:

(i) such undertaking is secured by a surety bond or some other appropriate security or the Trust shall be insured against losses arising out of any such advances; or

(ii) a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or legal counsel meeting the requirement in Section 5.3(b)(iii)(B) above in a written opinion, shall determine, based upon a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the Covered Person ultimately will be found entitled to indemnification.

As used in this Section 5.3 a "Disinterested Trustee" is one (i) who is not an "Interested Person" of the Trust (including anyone who has been exempted from being an "Interested Person" by any rule, regulation or order of the Commission), and (ii) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or had been pending.

(e) With respect to any such determination or opinion referred to in clause
(b)(iii) above or clause (d)(ii) above, a rebuttable presumption shall be afforded that the Covered Person has not engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office in accordance with pronouncements of the Commission.

Section 5.4. No Bond Required. No Trustee, Trustee Emeritus or officer shall be obligated to give any bond or other security for the performance of any of his or her duties hereunder.

Section 5.5. No Duty of Investigation; Notice in Trust Instruments. No purchaser, lender, shareholder servicing agent, Transfer Agent or other Person dealing with the Trustees or any officer, employee or agent of the Trust shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, instrument, certificate, Share, other security of the Trust or undertaking, and every other act or thing whatsoever executed in


15

connection with the Trust shall be conclusively presumed to have been executed or done by the executors thereof only in their capacity as Trustees under the Declaration or in their capacity as officers, employees or agents of the Trust. Every written obligation, contract, instrument, certificate, Share, other security of the Trust or undertaking made or issued by the Trustees or officers shall recite that the same is executed or made by them not individually, but as or on behalf of Trustees under the Declaration, and that the obligations of any such instrument are not binding upon any of the Trustees, officers or Shareholders individually, but bind only the Trust estate, and may contain any further recital deemed appropriate, but the omission of such recital shall not operate to bind any of the Trustees, officers or Shareholders individually. The Trustees may maintain insurance for the protection of the Trust Property, Shareholders, Trustees, Trustees Emeritus, officers, employees and agents in such amount as the Trustees shall deem adequate to cover possible tort liability, and such other insurance as the Trustees in their sole judgment shall deem advisable.

Section 5.6. Good Faith Action; Reliance on Experts. The exercise by the Trustees or the officers of the Trust of their powers and discretions hereunder in good faith and with reasonable care under the circumstances then prevailing shall be binding upon everyone interested. The Trustees or the officers of the Trust shall not be liable for errors of judgment or mistakes of fact or law. Each Trustee and officer or employee of the Trust shall, in the performance of his or her duties, be under no liability and fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Trust, upon advice of counsel, or upon reports made to the Trust by any of its officers or employees or by the Investment Adviser, the Distributor, Transfer Agent, custodian, any shareholder servicing agent, selected dealers, accountants, appraisers or other experts or consultants selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or expert may also be a Trustee.

Section 5.7. Derivative Actions. No Shareholder shall have the right to bring or maintain any court action, proceeding or claim on behalf of the Trust or any series or class thereof without first making demand on the Trustees requesting the Trustees to bring or maintain such action, proceeding or claim. Such demand shall be excused only when the plaintiff makes a specific showing that irreparable injury to the Trust or any series or class thereof would otherwise result, or if a majority of the Board of Trustees, or a majority of any committee established to consider the merits of such action, has a material personal financial interest in the action at issue. A Trustee shall not be deemed to have a personal financial interest in an action or otherwise be disqualified from ruling on a Shareholder demand by virtue of the fact that such Trustee receives remuneration from his or her service on the Board of Trustees of the Trust or on the boards of one or more investment companies


16

with the same or an affiliated investment adviser or underwriter, or the amount of such remuneration.

Such demand shall be mailed to the Secretary or Clerk of the Trust at the Trust's principal office and shall set forth in reasonable detail the nature of the proposed court action, proceeding or claim and the essential facts relied upon by the Shareholder to support the allegations made in the demand. The Trustees shall consider such demand within 45 days of its receipt by the Trust. In their sole discretion, the Trustees may submit the matter to a vote of Shareholders of the Trust or any series or class thereof, as appropriate. Any decision by the Trustees to bring, maintain or settle (or not to bring, maintain or settle) such court action, proceeding or claim, or to submit the matter to a vote of Shareholders, shall be made by the Trustees in their business judgment and shall be binding upon the Shareholders. Any decision by the Trustees to bring or maintain a court action, proceeding or suit on behalf of the Trust or any series or class thereof shall be subject to the right of the Shareholders under Section 6.8 of the Declaration to vote on whether or not such court action, proceeding or suit should or should not be brought or maintained.

ARTICLE VI

SHARES OF BENEFICIAL INTEREST

Section 6.1. Beneficial Interest. The interest of the beneficiaries hereunder may be divided into transferable Shares of Beneficial Interest (without par value), which may be divided into one or more series and classes as provided in Sections 6.9 and 6.10 hereof. The number of Shares authorized hereunder is unlimited. All Shares issued hereunder including, without limitation, Shares issued in connection with a dividend in Shares or a split of Shares, shall be fully paid and non-assessable.

Section 6.2. Rights of Shareholders. The ownership of the Trust Property of every description and the right to conduct any business hereinbefore described are vested exclusively in the Trustees, and the Shareholders shall have no interest therein other than the beneficial interest conferred by their Shares, and they shall have no right to call for any partition or division of any property, profits, rights or interests of the Trust nor can they be called upon to assume any losses of the Trust or suffer an assessment of any kind by virtue of their ownership of Shares. The Shares shall be personal property giving only the rights specifically set forth in the Declaration. The Shares shall not entitle the holder to preference, preemptive, appraisal, conversion or exchange rights, except as the Trustees may determine with respect to any series or class of Shares. By becoming a Shareholder each Shareholder shall be held expressly to have assented to and agreed to be bound by the provisions of the Declaration.


17

Section 6.3. Trust Only. It is the intention of the Trustees to create only the relationship of Trustee and beneficiary between the Trustees and each Shareholder from time to time. It is not the intention of the Trustees to create a general partnership, limited partnership, joint stock association, corporation, bailment or any form of legal relationship other than a trust. Nothing in the Declaration shall be construed to make the Shareholders, either by themselves or with the Trustees, partners or members of a joint stock association.

Section 6.4. Issuance of Shares. The Trustees, in their discretion may, from time to time without vote of the Shareholders, issue Shares, in addition to the then issued and outstanding Shares and Shares held in the treasury, to such party or parties and for such amount and type of consideration, including cash or property, at such time or times, and on such terms as the Trustees may deem best, and may in such manner acquire other assets (including the acquisition of assets subject to, and in connection with, the assumption of liabilities) and businesses. In connection with any issuance of Shares, the Trustees may issue fractional Shares. The Trustees may from time to time divide or combine the Shares of any series or class into a greater or lesser number without thereby changing their proportionate beneficial interests in Trust Property allocated or belonging to such series or class. Contributions to the Trust may be accepted for, and Shares shall be redeemed as, whole Shares and/or 1/1,000ths of a Share or integral multiples thereof.

Section 6.5. Register of Shares. A register or registers shall be kept at the principal office of the Trust or at an office of the Transfer Agent which shall contain the names and addresses (which may be addresses for electronic delivery) of the Shareholders and the number of Shares held by them respectively and a record of all transfers thereof. Such register shall be conclusive as to who are the holders of the Shares and who shall be entitled to receive dividends or distributions or otherwise to exercise or enjoy the rights of Shareholders. No Shareholder shall be entitled to receive payment of any dividend or distribution, nor to have notice given to that Shareholder as provided herein or in the By-Laws, until the Shareholder has given his or her address to the Transfer Agent or such other officer or agent of the Trustees as shall keep the said register for entry thereon. It is not contemplated that certificates will be issued for the Shares; however, the Trustees, in their discretion, may authorize the issuance of Share certificates and promulgate appropriate rules and regulations as to their use.

Section 6.6. Transfer of Shares. Shares shall be transferable on the records of the Trust only by the record holder thereof or by the record holder's agent thereunto authorized in writing, upon delivery to the Trustees or, if there is a Transfer Agent with respect to such Shares, the Transfer Agent of a duly executed instrument of transfer together with any certificate or certificates (if issued) for such Shares and such evidence of the genuineness of each such execution and authorization and of other matters as may reasonably


18

be required. Upon such delivery the transfer shall be recorded on the register of the Trust. Until such record is made, the Shareholder of record shall be deemed to be the holder of such Shares for all purposes hereunder and neither the Trustees nor any Transfer Agent or registrar nor any officer, employee or agent of the Trust shall be affected by any notice of the proposed transfer.

Any Person becoming entitled to any Shares in consequence of the death, bankruptcy, or incompetence of any Shareholder, or otherwise by operation of law, shall be recorded on the register of Shares as the holder of such Shares upon production of the proper evidence thereof to the Trustees or the Transfer Agent; but until such record is made, the Shareholder of record shall be deemed to be the holder of such Shares for all purposes hereunder and neither the Trustees nor any Transfer Agent or registrar nor any officer or agent of the Trust shall be affected by any notice of such death, bankruptcy or incompetence, or other operation of law.

Section 6.7. Notices. Any and all notices to which any Shareholder may be entitled and any and all communications shall be deemed duly served or given (i) if mailed, postage prepaid, addressed to any Shareholder of record at the Shareholder's last known address as recorded on the register of the Trust, (ii) if sent by electronic transmission to the Shareholder of record at the Shareholder's last known address for electronic delivery as recorded on the register of the Trust, (iii) if mailed or sent by electronic delivery to one or more members of the Shareholder's household in accordance with applicable law or regulation, or (iv) if otherwise sent in accordance with applicable law or regulation.

Section 6.8. Voting Powers. The Shareholders shall have power to vote only
(i) for the election of Trustees when that issue is submitted to Shareholders, and for the removal of Trustees as provided in Section 2.2 hereof, (ii) with respect to any investment advisory or management contract on which a shareholder vote is required by the 1940 Act, (iii) with respect to termination of the Trust or any series or class to the extent and as provided in Section 9.2 hereof, (iv) with respect to any amendment of the Declaration to the extent and as provided in Section 9.3 hereof, (v) with respect to any merger, consolidation or sale of assets to the extent and as provided in Section 9.4 hereof, (vi) to the same extent as the stockholders of a Massachusetts business corporation as to whether or not a court action, proceeding or claim should or should not be brought or maintained derivatively or as a class action on behalf of the Trust or the Shareholders, and (vii) with respect to such additional matters relating to the Trust as may be required by the Declaration, the By-Laws or any registration of the Trust with the Commission (or any successor agency) or any other regulator having jurisdiction over the Trust, or as the Trustees may consider necessary or desirable.


19

A Shareholder of each series or class shall be entitled to one vote for each dollar of net asset value (number of Shares owned times net asset value per Share) of such series or class, on each matter on which such Shareholder is entitled to vote and each fractional dollar amount shall be entitled to a proportionate fractional vote, except that the Trustees may, in conjunction with the establishment of any series or class of Shares (but subject to applicable law), establish conditions under which the several series or classes shall have separate or no voting rights. Shares held in the treasury of the Trust shall not be voted.

Except when a larger vote is required by applicable law or by any provision of the Declaration or the By-Laws, if any, Shares representing a majority of the voting power of the Shares voted in person or by proxy shall decide any questions and a plurality shall elect a Trustee, provided that where any provision of law or of the Declaration requires that the holders of any series or class shall vote as a series or class, then Shares representing a majority of the voting power of the Shares of that series or class voted on the matter shall decide that matter insofar as that series or class is concerned, and provided further that abstentions and broker non-votes shall not be counted as votes cast but shall be counted as being present for purposes of determining the existence of a quorum.

Shares of all series shall be voted in the aggregate on any matter submitted to a vote of the Shareholders of the Trust except as provided in
Section 6.9(g) hereof. There shall be no cumulative voting in the election of Trustees. Until Shares are issued and during any period when no Shares are outstanding, the Trustees may exercise all rights of Shareholders and may take any action required by law, the Declaration or the By-Laws to be taken by Shareholders. The By-Laws may include further provisions for Shareholder votes and meetings and related matters.

Section 6.9. Series of Shares. Shares of the Trust may be divided into series, the number and relative rights, privileges and preferences of which shall be established and designated by the Trustees, in their discretion, in accordance with the terms of this Section 6.9. The Trustees may from time to time exercise their power to authorize the division of Shares into one or more series by establishing and designating one or more series of Shares upon and subject to the following provisions:

(a) All Shares shall be identical (subject to such variations between classes of Shares as may be permitted in accordance with the terms of Section 6.10 hereof) except that there may be such variations between different series as are approved by the Trustees and as are consistent with applicable law.

(b) The number of authorized Shares and the number of Shares of each series that may be issued shall be unlimited. The Trustees may classify or


20

reclassify any Shares of any series, including outstanding Shares, unissued Shares and Shares previously issued and reacquired, into one or more series that may be established and designated from time to time. The Trustees may hold as treasury shares (of the same or some other series), reissue for such consideration and on such terms as they may determine, or cancel any Shares of any series reacquired by the Trust at their discretion from time to time.

(c) All consideration received by the Trust for the issue or sale of Shares of a particular series, together with all assets in which such consideration is invested or reinvested, all income, earnings, profits, and proceeds thereof, including any proceeds derived from the sale, exchange or liquidation of such assets, and any funds or payments derived from any reinvestment of such proceeds in whatever form the same may be, shall irrevocably belong to that series for all purposes, subject only to the rights of creditors of such series, and shall be so recorded upon the books of account of the Trust. In the event that there are any assets, income, earnings, profits and proceeds thereof, funds, or payments which are not readily identifiable as belonging to any particular series, the Trustees shall allocate them among any one or more of the series established and designated from time to time in such manner and on such basis as they, in their sole discretion, deem fair and equitable. Each such allocation by the Trustees shall be conclusive and binding upon the Shareholders of all series for all purposes. No holder of Shares of any particular series shall have any claim on or right to any assets allocated or belonging to any other series of Shares. No holder of Shares of any particular series shall be entitled to participate in a derivative or class action on behalf of any other series or the Shareholders of any other series.

(d) The assets belonging to each particular series shall be charged with the liabilities of the Trust in respect of that series and all expenses, costs, charges and reserves attributable to that series, and any general liabilities, expenses, costs, charges or reserves of the Trust which are not readily identifiable as belonging to any particular series shall be allocated and charged by the Trustees to and among any one or more of the series established and designated from time to time in such manner and on such basis as the Trustees, in their sole discretion, deem fair and equitable. Each allocation of liabilities, expenses, costs, charges and reserves by the Trustees shall be conclusive and binding upon the holders of all series for all purposes. The Trustees shall have full discretion, to the extent not inconsistent with the 1940 Act, to determine which items shall be treated as income and which items as capital; and each such determination and allocation shall be conclusive and binding upon the Shareholders. Under no circumstances shall the assets allocated or belonging to any particular series be charged with liabilities attributable to any other series. All Persons who have extended credit which has been allocated to a particular series, or who have a claim or contract which has been allocated to any particular series, shall look only to the assets of that particular series for payment of such credit, claim or contract.


21

(e) The power of the Trustees to invest and reinvest the Trust Property allocated or belonging to any particular series shall be governed by Section 3.2 hereof unless otherwise provided in the instrument of the Trustees establishing such series.

(f) Each Share of a series shall represent a beneficial interest in the net assets allocated or belonging to such series only, and such interest shall not extend to the assets of the Trust generally. Dividends and distributions on Shares of a particular series may be paid with such frequency as the Trustees may determine, which may be monthly or otherwise, pursuant to a standing resolution or resolutions adopted only once or with such frequency as the Trustees may determine, to the holders of Shares of that series only, from such of the income and capital gains, accrued or realized, from the assets belonging to that series, as the Trustees may determine, after providing for actual and accrued liabilities belonging to that series. Subject to differences among classes, all dividends and distributions on Shares of a particular series shall be distributed pro rata to the holders of that series in proportion to the number and value of Shares of that series held by such holders at the date and time of record established for the payment of such dividends or distributions. Shares of any particular series of the Trust may be redeemed solely out of Trust Property allocated or belonging to that series. Upon liquidation or termination of a series of the Trust, Shareholders of such series shall be entitled to receive a pro rata share of the net assets of such series only.

(g) Notwithstanding any provision hereof to the contrary, on any matter submitted to a vote of the Shareholders of the Trust, all Shares of all series then entitled to vote shall be voted in the aggregate, except that (i) when required by the 1940 Act to be voted by individual series or class, Shares shall not be voted in the aggregate, and (ii) when the Trustees have determined that a matter affects only the interests of Shareholders of particular series or classes of Shares, only Shareholders of such series or classes of Shares, as applicable, shall be entitled to vote thereon.

Section 6.10. Classes of Shares. The Trustees may, in their discretion, authorize the division of Shares of the Trust (or any series of the Trust) into one or more classes, the number and relative rights, privileges and preferences of which shall be established and designated by the Trustees, in their discretion, in accordance with the terms of the 1940 Act. The number of Shares of each class that may be issued is unlimited, and the Trustees may classify or reclassify any shares of any class, including outstanding Shares, into one or more classes that may be established and designated from time to time. All Shares of a class shall be identical with each other and with the Shares of each other class of the Trust or the same series of the Trust (as applicable), except for such variations between classes as may be approved by the Board of Trustees and not prohibited by the 1940 Act.


22

Section 6.11 Series and Class Designations. The establishment and designation of any series or class of Shares shall be effective (a) upon the execution by a majority of the then Trustees of an instrument setting forth such establishment and designation and the relative rights and preferences of such series or class, (b) upon the vote of a majority of the Trustees as set forth in an instrument executed by an officer of the Trust, or (c) at such other time as the instrument referred to in the foregoing clause (a) or the vote referred to in the foregoing clause (b) may provide. Subject to Section 9.2 hereof, the Trustees may at any time by an instrument executed by a majority of their number abolish any series or class and the establishment and designation thereof. Each instrument referred to in this paragraph shall be an amendment to the Declaration.

The series of Shares existing as of the date hereof are set forth in Appendix A hereto.

The classes of Shares of each series existing as of the date hereof are set forth in Appendix B hereto.

ARTICLE VII

REDEMPTIONS

Section 7.1. Redemptions. All Shares shall be redeemable based on a redemption price determined in accordance with this Section 7.1 and Article VIII of the Declaration. Redeemed Shares may be resold by the Trust. The Trust shall redeem the Shares at the price determined as hereinafter set forth, upon acceptance of the appropriately verified application of the record holder thereof (or upon such other form of request as the Trustees may determine) at such office or agency as may be designated from time to time for that purpose in the Trust's then effective registration statement under the Securities Act of 1933 and the 1940 Act. The Trustees may from time to time specify additional conditions, not inconsistent with the 1940 Act, in the Trust's registration statement regarding the redemption of Shares. Shares shall be redeemed at the net asset value thereof next determined after acceptance of such request, less any applicable redemption fee or sales charge as permitted under applicable law.

Subject to Section 7.2 hereof, payment for said Shares shall be made to the Shareholder in cash or in property at such time and in such manner not inconsistent with the 1940 Act or other applicable law. Except as expressly determined by the Trustees, Shareholders shall not have the right to have Shares redeemed in-kind.


23

Section 7.2. Suspension of Right of Redemption. The Trust may declare a suspension of the right of redemption or postpone the date of payment of the redemption proceeds of any series or class as permitted under the 1940 Act. Such suspension shall take effect at such time as the Trust shall specify, and thereafter there shall be no right of redemption or payment of the redemption proceeds until the Trust shall declare the suspension at an end. In the case of a suspension of the right of redemption, a Shareholder may either withdraw the Shareholder's request for redemption or receive payment based on the net asset value existing after the termination of the suspension.

Section 7.3. Redemption of Shares; Disclosure of Holding. The Trustees may, in their discretion, require the Trust to redeem Shares held by any Shareholder for any reason under terms set by the Trustees, including, but not limited to,
(i) the determination of the Trustees that direct or indirect ownership of Shares of any series has or may become concentrated in such Shareholder to an extent that would disqualify that series as a regulated investment company under the Internal Revenue Code of 1986, as amended (or any successor statute thereto), (ii) the failure of a Shareholder to supply a tax identification number if required to do so, (iii) the failure of a Shareholder to pay when due for the purchase of Shares issued to that Shareholder, (iv) the value of a Shareholder's Shares being less than a minimum amount established from time to time by the Trustees, (v) failure of a Shareholder to meet or maintain the qualifications for ownership of a particular class of Shares, or (vi) the determination by the Trustees or pursuant to policies adopted by the Trustees that ownership of Shares by a particular Shareholder is not in the best interests of the remaining Shareholders of the Trust or applicable series or class. The redemption shall be effected at the redemption price and in the manner provided in Section 7.1 hereof.

The holders of Shares or other securities of the Trust shall upon demand disclose to the Trustees in writing such information with respect to direct and indirect ownership of Shares or other securities of the Trust as the Trustees deem necessary to comply with the provisions of the Internal Revenue Code of 1986, as amended (or any successor statute), or to comply with the requirements of any other law or regulation, and such ownership of Shares may be disclosed by the Trustees if so requested by such law or regulation.

ARTICLE VIII

DETERMINATION OF NET ASSET VALUE,
NET INCOME AND DISTRIBUTIONS; REDUCTION IN SHARES

The Trustees, in their absolute discretion, may prescribe and shall set forth in the By-Laws or in a duly adopted vote of the Trustees such bases and times for determining the per Share net asset value of the Shares or net income, or the declaration and payment of dividends and distributions, as they


24

may deem necessary or desirable. With respect to any series that holds itself out as a money market or stable value fund, the Trustees shall have the power to reduce the number of outstanding Shares of the series by reducing the number of Shares in the account of each Shareholder on a pro rata basis, so as to maintain the net asset value per Share of such series at a constant dollar amount.

ARTICLE IX

DURATION; TERMINATION OF TRUST;
AMENDMENT; MERGERS, ETC.

Section 9.1. Duration. The Trust shall continue without limitation of time but subject to the provisions of this Article IX.

Section 9.2. Termination of Trust. (a) The Trust may be terminated at any time (i) by a Majority Shareholder Vote of the holders of its Shares, or (ii) by the Trustees by written notice to the Shareholders. Any series of the Trust, or any class of any series, may be terminated at any time (i) by a Majority Shareholder Vote of the holders of Shares of that series or class, or (ii) by the Trustees by written notice to the Shareholders of that series or class. Upon the termination of the Trust or any series of the Trust:

(i) The Trust or series of the Trust shall carry on no business except for the purpose of winding up its affairs;

(ii) The Trustees shall proceed to wind up the affairs of the Trust or series of the Trust and all the powers of the Trustees under the Declaration shall continue until the affairs of the Trust or series of the Trust shall have been wound up, including the power to fulfill or discharge the contracts of the Trust or series of the Trust, collect its assets, sell, convey, assign, exchange, transfer or otherwise dispose of all or any part of the remaining Trust Property or Trust Property of the series to one or more Persons at public or private sale for consideration which may consist in whole or in part of cash, securities or other property of any kind, discharge or pay its liabilities, and to do all other acts appropriate to liquidate its business; and

(iii) After paying or adequately providing for the payment of all liabilities, and upon receipt of such releases, indemnities and refunding agreements as they deem necessary for their protection, the Trustees may distribute the remaining Trust Property or Trust Property of the series, in cash or in kind or partly in cash and partly in kind, among the Shareholders of the Trust or the series according to their respective rights.

The foregoing provisions shall also apply, with appropriate modifications as determined by the Trustees, to the termination of any class.


25

(b) After termination of the Trust or series or class and distribution to the Shareholders of the Trust or series or class as herein provided, a majority of the Trustees shall execute and lodge among the records of the Trust an instrument in writing setting forth the fact of such termination, and the Trustees shall thereupon be discharged from all further liabilities and duties hereunder with respect to the Trust or series or class, and the rights and interests of all Shareholders of the Trust or series or class shall thereupon cease.

Section 9.3. Amendment Procedure. (a) Except as specifically provided herein, the Trustees may, without any Shareholder vote, amend or otherwise supplement the Declaration by making an amendment, a Declaration of Trust supplemental hereto or an amended and restated Declaration. Without limiting the foregoing power reserved to the Trustees, the Trustees may, without any Shareholder vote, amend the Declaration to designate or redesignate series or classes, to change the name or principal office of the Trust, to supply any omission, to cure, correct or supplement any ambiguous, defective or inconsistent provision hereof, or if they deem it necessary or advisable, to conform the Declaration to the requirements of applicable law, including the 1940 Act and the Internal Revenue Code of 1986, as amended, but the Trustees shall not be liable for failing to do so. Shareholders shall have the right to vote on (i) any amendment that would affect their right to vote granted in
Section 6.8; (ii) any amendment to Section 9.3(a) or (b); (iii) any amendment as may be required by law, or by the Trust's registration statement, to be approved by Shareholders; and (iv) any amendment submitted to them by the Trustees. Any amendment on which Shareholders have the right to vote shall require a Majority Shareholder Vote of the Shareholders of the Trust, or the written consent, without a meeting, of the holders of Shares representing not less than a majority of the voting power of the Shares of the Trust. Notwithstanding the foregoing, if the Trustees shall determine that any amendment required or permitted to be submitted to Shareholders would affect only the interest of Shareholders of particular series or classes of Shares, then only Shareholders of such series or classes, as applicable, shall be entitled to vote thereon, and no vote of Shareholders of any other series or classes shall be required.

(b) Nothing contained in the Declaration shall permit the amendment of the Declaration to impair the exemption from personal liability of the Shareholders, former Shareholders, Trustees, Trustees Emeritus, officers, employees and agents of the Trust or to permit assessments upon Shareholders or former Shareholders. Notwithstanding anything else herein, any amendment to Section 5.3 shall not limit the rights to indemnification or insurance provided therein with respect to actions or omissions of persons entitled to indemnification under such
Section prior to such amendment.


26

(c) A certificate signed by a majority of the Trustees setting forth an amendment and reciting that it was duly adopted by the Shareholders (if applicable) or by the Trustees as aforesaid or a copy of the Declaration, as amended, and executed by a majority of the Trustees, shall be conclusive evidence of such amendment when lodged among the records of the Trust.

(d) Notwithstanding any other provision hereof, until such time as Shares of a particular series or class are first issued the Declaration may be terminated or amended in any respect as to that series or class, and as to any series or class in which Shares are not outstanding, by the affirmative vote of a majority of the Trustees or by an instrument signed by a majority of the Trustees.

Section 9.4. Merger, Consolidation and Sale of Assets. Subject to applicable law and except as otherwise provided in Section 9.5 hereof, the Trust or any series or class thereof may merge or consolidate with any other corporation, association, trust or other organization or may sell, lease or exchange all or substantially all of the Trust Property (or all or substantially all of the Trust Property allocated or belonging to a particular series or class of the Trust) including its good will, upon such terms and conditions and for such consideration when and as authorized (a) at any meeting of Shareholders called for such purpose by a Majority Shareholder Vote of all series of the Trust voting as a single class if the entire Trust is merging, consolidating or disposing of assets, by a Majority Shareholder Vote of the particular series if the entire series is merging, consolidating or disposing of assets, or by a Majority Shareholder Vote of a class if only that class is merging, consolidating or disposing of assets, or (b) by the written consent, without a meeting, of the holders of Shares representing a majority of the voting power of the outstanding Shares of all series of the Trust voting as a single class, or of the particular series or class as described above. Any such merger, consolidation, sale, lease or exchange shall be deemed for all purposes to have been accomplished under and pursuant to the statutes of The Commonwealth of Massachusetts. Such transactions may be effected through share-for-share exchanges, transfers or sales of assets, in-kind redemptions and purchases, exchange offers, or any other method approved by the Trustees. Nothing contained herein shall be construed as requiring approval of Shareholders for any recapitalization or reclassification of any series or class, for any sale of assets in the ordinary course of the business of the Trust, or for any transaction, whether deemed a merger, consolidation, reorganization or exchange of shares or otherwise, whereby the Trust issues shares of one or more series or classes in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity.

Section 9.5. Incorporation, Reorganization. The Trustees may, without the vote or consent of Shareholders, cause to be organized or assist in


27

organizing a corporation or corporations under the laws of any jurisdiction, or any other trust (or series or class of a trust), unit investment trust, partnership, limited liability company, association or other organization to acquire all or a portion of the Trust Property (or all or a portion of the Trust Property allocated or belonging to a particular series or class) or to carry on any business in which the Trust shall directly or indirectly have any interest, and to sell, convey and transfer such Trust Property to any such corporation, trust (or series or class of a trust), partnership, limited liability company, association or organization in exchange for the shares or securities thereof or otherwise, and to lend money to, subscribe for the shares or securities of, and enter into any contracts with any such corporation, trust, partnership, association or organization in which the Trust holds or is about to acquire shares or any other interest. The Trustees may also, without the vote or consent of Shareholders, cause a merger or consolidation between the Trust or any successor thereto and any such corporation, trust (or series or class of a trust), partnership, association or other organization if and to the extent permitted by law. The Trustees shall provide written notice to affected Shareholders of each transaction pursuant to this Section 9.5. Such transactions may be effected through share-for-share exchanges, transfers or sales of assets, in-kind redemptions and purchases, exchange offers, or any other method approved by the Trustees.

ARTICLE X

MISCELLANEOUS

Section 10.1. Filing. The Declaration and any subsequent amendment hereto shall be filed in the office of the Secretary of The Commonwealth of Massachusetts and in such other place or places as may be required under the laws of The Commonwealth of Massachusetts and may also be filed or recorded in such other places as the Trustees deem appropriate, provided that the failure to so file shall not invalidate this instrument or any properly authorized amendment hereto. Each amendment so filed shall be accompanied by a certificate signed and acknowledged by an officer or Trustee stating that such action was duly taken in a manner provided herein, and unless such amendment or such certificate sets forth some other time for the effectiveness of such amendment, such amendment shall be effective upon its filing. A restated Declaration, integrating into a single instrument all of the provisions of the Declaration which are then in effect and operative, may be executed from time to time by a majority of the Trustees and shall, upon filing with the Secretary of The Commonwealth of Massachusetts, be conclusive evidence of all amendments contained therein and may thereafter be referred to in lieu of the original Declaration and the various amendments thereto.

Section 10.2. Governing Law. The Declaration is executed by the Trustees and delivered in The Commonwealth of Massachusetts and with reference to the


28

laws thereof, and the rights of all parties and the validity and construction of every provision hereof shall be subject to and construed according to the laws of said Commonwealth. The Trust shall be of the type commonly called a Massachusetts business trust, and without limiting the provisions hereof, the Trust may exercise all powers which are ordinarily exercised by such a trust, and the absence of a specific reference herein to any such power, privilege, or action shall not imply that the Trust may not exercise such power or privilege or take such action.

Section 10.3. Principal Office. The principal office of the Trust is 500 Boylston Street, Boston, Massachusetts. The Trustees, without a vote of Shareholders, may change the principal office of the Trust.

Section 10.4. Counterparts. The Declaration may be simultaneously executed in several counterparts, each of which shall be deemed to be an original, and such counterparts, together, shall constitute one and the same instrument, which shall be sufficiently evidenced by any such original counterpart.

Section 10.5. Reliance by Third Parties. Any certificate executed by an individual who, according to the records of the Trust, appears to be an officer or Trustee hereunder, certifying to: (i) the number or identity of Trustees or Shareholders, (ii) the due authorization of the execution of any instrument or writing, (iii) the form of any vote passed at a meeting of Trustees or Shareholders, (iv) the fact that the number of Trustees or Shareholders present at any meeting or executing any written instrument satisfies the requirements of the Declaration, (v) the form of any By-Laws adopted by or the identity of any officers elected by the Trustees, or (vi) the existence of any fact or facts which in any manner relates to the affairs of the Trust, shall be conclusive evidence as to the matters so certified in favor of any Person dealing with the Trustees and their successors.

Section 10.6. Provisions in Conflict with Law or Regulations.

(a) The provisions of the Declaration are severable, and if the Trustees shall determine, with the advice of counsel, that any of such provisions is in conflict with the 1940 Act, the regulated investment company or other provisions of the Internal Revenue Code of 1986, as amended, or with other applicable laws and regulations, the conflicting provision shall be deemed never to have constituted a part of the Declaration; provided, however, that such determination shall not affect any of the remaining provisions of the Declaration or render invalid or improper any action taken or omitted prior to such determination.

(b) If any provision of the Declaration shall be held invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall attach only to such provision in such jurisdiction and shall not in any manner affect such provision in any other jurisdiction or any other provision of the Declaration in any jurisdiction.

Establishment and Designation of Series of Shares of Beneficial Interest (without par value)

The Trustees of the Trust, acting pursuant to the Trust's Declaration, have previously established and designated the series (each, a "Fund") of Shares of Beneficial Interest listed below.

1. The Funds are as follows:

MFS Bond Fund;
MFS Emerging Opportunities Fund; MFS High Quality Bond Fund;
MFS Intermediate Investment Grade Bond Fund; MFS Large Cap Value Fund;
MFS Limited Maturity Fund;
MFS Municipal Limited Maturity Fund; and MFS Research Bond Fund.

2. Each Fund shall be authorized to hold cash, invest in securities, instruments and other property and use investment techniques as from time to time described in the Trust's then currently effective registration statement under the Securities Act of 1933 to the extent pertaining to the offering of Shares of the Fund. Each Share of each Fund shall be redeemable as provided in the Declaration. Subject to differences among classes, each Share of each Fund shall be entitled to vote on matters on which Shares of the Fund shall be entitled to vote as provided in Section 6.8 of the Trust's Declaration of Trust, shall represent a pro rata beneficial interest in the assets allocated or belonging to the Fund, and shall be entitled to receive its pro rata share of the net assets of the Fund upon liquidation of the Fund, all as provided in
Section 6.9 of the Declaration of Trust. The proceeds of sales of Shares of each Fund, together with any income and gain thereon, less any diminution or expenses thereof, shall irrevocably belong to the Fund, unless otherwise required by law.

3. Shareholders of each Fund shall vote separately as a class on any matter to the extent required by, and any matter shall have been deemed effectively acted upon with respect to the Fund as provided in, Rule 18f-2, as from time to time in effect, under the 1940 Act or any successor rule, and the Declaration.

4. The assets and liabilities of the Trust shall be allocated among each Fund and any series of the Trust designated in the future as set forth in
Section 6.9 of the Declaration.


2

5. Subject to the provisions of Section 6.9 and Article IX of the Declaration, the Trustees (including any successor Trustees) shall have the right at any time and from time to time to reallocate assets and expenses or to change the designation of each Fund, or to otherwise change the special and relative rights of each Fund.

6. Any Fund may be terminated by the Trustees at any time by written notice to the Shareholders of the Fund in accordance with Article IX of the Declaration.


Appendix B

Establishment and Designation
of Classes

Pursuant to Section 6.10 of the Declaration, the Trustees have divided the Shares of each series of the Trust to create the classes of Shares, within the meaning of Section 6.10, listed below.

1. The classes of Shares of MFS Municipal Limited Maturity Fund are designated "Class A Shares," "Class B Shares" and "Class C Shares."

The classes of Shares of MFS Bond Fund, MFS Emerging Opportunities Fund, MFS High Quality Bond Fund, MFS Intermediate Investment Grade Bond Fund, MFS Large Cap Value Fund, MFS Limited Maturity Fund and MFS Research Bond Fund are designated "Class A Shares," "Class B Shares," "Class C Shares" and "Class I Shares."

2. Shares of each class are entitled to all the rights and preferences accorded to Shares under the Declaration. The designation of classes hereby shall not impair the power of the Trustees from time to time to designate additional classes of shares.

3. For Shares of each class, the purchase price, the method of determination of the net asset value, the price, the terms and manner of redemption, any conversion feature, the relative dividend rights of holders thereof, and any other rights, privileges, features or qualifications, shall be established by the Trustees of the Trust in accordance with the Declaration and shall be set forth in the current prospectus and statement of additional information of the Trust or any series thereof relating to the applicable series, as amended from time to time, contained in the Trust's registration statement under the Securities Act of 1933, as amended.

4. Subject to the applicable provisions of the 1940 Act and the Declaration, the Trustees may from time to time modify the preferences, voting powers, rights and privileges of any of the classes designated hereby without any action or consent of Shareholders.

5. A class of Shares of any series of the Trust may be terminated by the Trustees at any time by written notice to the Shareholders of the class in accordance with Article IX of the Declaration.

2. Class 529A Shares, Class 529B Shares and Class 529C Shares shall be entitled to all the rights and preferences accorded to shares under the Declaration;

4. Class 529A Shares, Class 529B Shares and Class 529C Shares shall vote together as a single class except that shares of a class may vote separately on matters affecting only that class and shares of a class not affected by a matter will not vote on that matter; and

5. A class of shares of any series of the Trust may be terminated by the Trustees by written notice to the Shareholders of the class.


IN WITNESS WHEREOF, a majority of the Trustees of the Trust have executed this amendment, in one or more counterparts, all constituting a single instrument, as an instrument under seal in The Commonwealth of Massachusetts, as of this 18th day of April, 2002 and further certify, as provided by the provisions of Section 9.3(c) of the Declaration, that this amendment was duly adopted by the undersigned in accordance with Section 9.3(a) of the Declaration.

INVESTMENT ADVISORY AGREEMENT

INVESTMENT ADVISORY AGREEMENT, dated this 1st day of January, 2002, by and between MFS SERIES TRUST IX, a Massachusetts business trust (the "Trust"), on behalf of its series of shares (each a "Fund") listed on Appendix A attached hereto, and MASSACHUSETTS FINANCIAL SERVICES COMPANY, a Delaware corporation (the "Adviser").

WITNESSETH:

WHEREAS, the Trust is engaged in business as an investment company registered under the Investment Company Act of 1940; and

WHEREAS, the Adviser is willing to provide services to each 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. (a) The Adviser shall provide each Fund with such investment advice and supervision as the latter may from time to time consider necessary for the proper supervision of its assets. The Adviser shall act as investment adviser to each Fund and as such shall furnish continuously an investment program and shall determine from time to time what securities or other instruments shall be purchased, sold or exchanged and what portion of the assets of each Fund shall be held uninvested, subject always to the restrictions of the Trust's Amended and Restated Declaration of Trust, dated January 1, 2002, and By-Laws, each as amended from time to time (respectively, the "Declaration" and the "By-Laws"), to the provisions of the Investment Company Act of 1940 and the Rules, Regulations and orders thereunder and to a Fund's then-current Prospectus and Statement of Additional Information. The Adviser also shall exercise voting rights, rights to consent to corporate actions and any other rights pertaining to a Fund's portfolio securities in accordance with the Adviser's policies and procedures as presented to the Trustees of the Trust from time to time. 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 shall be revoked.


(b) The Adviser shall take, on behalf of each 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 or other instruments for each Fund's account with brokers or dealers selected by it, and to that end, the Adviser is authorized as the agent of each Fund to give instructions to the Custodian of each Fund as to the deliveries of securities or other instruments and payments of cash for the account of each Fund. In connection with the selection of such brokers or dealers and the placing of such orders, the Adviser is directed to seek for each Fund the best overall price and execution available from responsible brokerage firms, taking account of all factors it deems relevant, including by way of illustration: price; the size of the transaction; the nature of the market for the security; the amount of the commission; the timing and impact of the transaction taking into account market prices and trends; the reputation, experience and financial stability of the broker or dealer involved; and the quality of services rendered by the broker or dealer in other transactions. In fulfilling this requirement, the Adviser shall not be deemed to have acted unlawfully or to have breached any duty, created by this Agreement or otherwise, solely by reason of its having caused a 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. Subject to seeking the best price and execution as described above, and in accordance with applicable rules and regulations, the Adviser also is authorized to consider sales of shares of each Fund or of other funds or accounts of the Adviser as a factor in the selection of brokers and dealers.

(c) The Adviser may from time to time enter into sub-investment advisory agreements with respect to a Fund with one or more investment advisers with such terms and conditions as the Adviser may determine, provided that such sub-investment advisory agreements have been approved in accordance with applicable provisions of the Investment Company Act of 1940 and any rules, regulations or orders of the Securities and Exchange Commission thereunder. Subject to the provisions of Article 6, the Adviser shall not be liable for any error of judgment or mistake of law by any sub-adviser or for any loss arising out of any investment made by any sub-adviser or for any act or omission in the execution and management of a Fund by any sub-adviser.

Article 2. Allocation of Charges and Expenses. (a) The Adviser shall furnish at its own expense investment advisory and administrative services, office space, equipment and clerical personnel necessary for servicing the investments of each

2

Fund and maintaining its organization, and investment advisory facilities and executive and supervisory personnel for managing the investments and effecting the portfolio transactions of each Fund. The Adviser shall arrange, if desired by the Trust, for directors, officers and employees of the Adviser to serve as Trustees, officers or agents of the Trust if duly elected or appointed to such positions and subject to their individual consent and to any limitations imposed by law.

(b) It is understood that the Trust and each Fund will pay all of their own expenses incurred in their operations and the offering of a Fund's shares, unless specifically provided otherwise in this Agreement or except to the extent that the Adviser agrees in a written instrument executed by the Adviser (specifically referring to this Article 2(b)) to assume or otherwise pay for specified expenses of the Trust or a Fund, 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 a Fund; fees and expenses of independent auditors, of legal counsel, and of any transfer agent, registrar or dividend disbursing agent of a Fund; expenses of repurchasing and redeeming shares and servicing shareholder accounts; expenses of preparing, printing and mailing stock certificates, shareholder reports, notices, proxy statements and reports to governmental officers and commissions; brokerage and other expenses connected with the execution, recording and settlement of portfolio security transactions; insurance premiums; fees and expenses of the custodian for all services to a Fund, including safekeeping of funds and securities and maintaining required books and accounts; expenses of calculating the net asset value of shares of a Fund; organizational and start up costs; such non-recurring or extraordinary expenses as may arise, including those relating to actions, suits or proceedings to which a Fund is a party or otherwise may have an exposure, and the legal obligation which a Fund may have to indemnify the Trust's Trustees and officers with respect thereto; and expenses relating to the issuance, registration and qualification of shares of a Fund and the preparation, printing and mailing of prospectuses for such purposes (except to the extent that any Distribution Agreement to which the Trust is a party provides that another party is to pay some or all of such expenses).

(c) The payment or assumption by the Adviser of any expenses of the Trust or a Fund that the Adviser is not obligated by this Agreement or otherwise to pay or assume shall not obligate the Adviser to pay or assume the same or any similar expenses of the Trust or a Fund on any subsequent occasion.

Article 3. Compensation of the Adviser. For the services to be rendered and the facilities provided, each Fund shall pay to the Adviser an investment advisory fee computed and paid monthly as set forth in Appendix B attached hereto. If the Adviser shall serve for less than the whole of any period specified in this Article 3, the compensation paid to the Adviser will be prorated.

3

Article 4. Additional Services. Should the Trust have occasion to request the Adviser or its affiliates to perform administrative or other additional services not herein contemplated or to request the Adviser or its affiliates to arrange for the services of others, the Adviser or its affiliates will act for the Trust on behalf of a Fund upon request to the best of its ability, with compensation for the services to be agreed upon with respect to each such occasion as it arises. No such agreement for additional services shall expand, reduce or otherwise alter the obligations of the Adviser, or the compensation that the Adviser is due, under this Agreement.

Article 5. Covenants of the Adviser. The Adviser agrees that it will not deal with itself, or with the Trustees of the Trust or the Trust's distributor, if any, as principals in making purchases or sales of securities or other property for the account of a Fund, except as permitted by the Investment Company Act of 1940 and any rules, regulations or orders of the Securities and Exchange Commission thereunder, will not take a long or short position in the shares of a Fund except as permitted by the applicable law, and will comply with all other provisions of the Declaration and the By-Laws and the then-current Prospectus and Statement of Additional Information of a Fund relative to the Adviser and its directors and officers.

Article 6. 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 a Fund, except for willful misfeasance, bad faith, gross negligence or reckless disregard of its duties and obligations hereunder. As used in this Article 6, the term "Adviser" shall include directors, officers and employees of the Adviser as well as that corporation itself.

Article 7. Activities of the Adviser. (a) The Trust acknowledges that the services of the Adviser to a Fund are not exclusive, the Adviser being free to render investment advisory and/or other services to others. The Trust further acknowledges that it is possible that, based on their investment objectives and policies, certain funds or accounts managed by the Adviser or its affiliates may at times take investment positions or engage in investment techniques which are contrary to positions taken or techniques engaged in on behalf of a Fund. Notwithstanding the foregoing, the Adviser will at all times endeavor to treat all of its clients in a fair and equitable manner.

(b) The Trust acknowledges that whenever a Fund and one or more other funds or accounts advised by the Adviser have available monies for investment, investments suitable and appropriate for each shall be allocated in a manner believed by the Adviser to be fair and equitable to each entity. Similarly, opportunities to sell securities or other investments shall be allocated in a manner believed by the Adviser

4

to be fair and equitable to each entity. The Trust acknowledges that in some instances this may adversely affect the size of the position that may be acquired or disposed of for a Fund.

(c) It is understood that the Trustees, officers and shareholders of the Trust are or may be or become interested in the Adviser, as directors, officers, employees, or otherwise and that directors, officers and employees of the Adviser are or may become similarly interested in the Trust, and that the Adviser may be or become interested in a Fund as a shareholder or otherwise.

Article 8. MFS Name. The Trust acknowledges that the names "Massachusetts Financial Services," "MFS" or any derivatives thereof or logos associated with those names (collectively, the "MFS Marks") are the valuable property of the Adviser and its affiliates. The Adviser grants the Trust and each Fund a non-exclusive and non-transferable right and sub-license to use the MFS Marks only so long as the Adviser serves as investment adviser to the Trust and each Fund. The Trust agrees that if the Adviser for any reason no longer serves as investment adviser to a Fund, and the Adviser so requests, that Fund promptly shall cease to use the MFS Marks and promptly shall amend its registration statement to delete any references to the MFS Marks. Likewise, the Trust agrees that if the Adviser for any reason no longer serves as investment adviser to any Fund of the Trust, and the Adviser so requests, the Trust promptly shall cease to use the MFS Marks and promptly shall amend its Declaration of Trust to delete any references to the MFS Marks. The Trust acknowledges that the Adviser may permit other clients to use the MFS Marks in their names or other material. For purposes of this Article, the Trust shall be deemed to have taken the required action "promptly" if such action is taken within 90 days of the Adviser no longer serving as the investment adviser to a Fund of the Trust, or from the date of the Adviser's request, as the case may be.

Article 9. Duration, Termination and Amendment of this Agreement. (a) This Agreement shall become effective with respect to the Trust on the date first written above, and shall become effective with respect to a Fund, if approved by the shareholders of such Fund, on the Effective Date for such Fund, as set forth in Appendix A attached hereto. Thereafter, this Agreement will remain in effect with respect to a Fund for a period of two years from that Fund's Effective Date as set forth in Appendix A, on which date it will terminate for that Fund unless its continuance is "specifically approved at least annually" (i) by the vote of a majority of the Trustees of the Trust who are not "interested persons" of the Trust or of the Adviser at a meeting specifically called for the purpose of voting on such approval, and (ii) by the Board of Trustees of the Trust, or by "vote of a majority of the outstanding voting securities" of the applicable Fund.

5

(b) This Agreement may be terminated as to the Trust or as to any Fund 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 applicable Fund, or by the Adviser, in each case 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".

(c) This Agreement may be amended with respect to a Fund only if such amendment is in writing signed by or on behalf of the Trust and the Adviser and is approved by "vote of a majority of the outstanding voting securities" of the applicable Fund (if such shareholder approval is required by the Investment Company Act of 1940).

(d) Any approval, renewal or amendment of this Agreement with respect to a Fund by "vote of a majority of the outstanding voting securities" of that Fund, by the Trustees of the Trust, or by a majority of the Trustees of the Trust who are not "interested persons" of the Trust or the Adviser, shall be effective to approve, renew or amend the Agreement with respect to that Fund notwithstanding
(i) that the approval, renewal or amendment has not been so approved as to any other Fund, or (ii) that the approval, renewal or amendment has not been approved by the vote of a majority of the outstanding voting securities of the Trust as a whole.

Article 10. Scope of Trust's Obligations. A copy of the Trust's Declaration of Trust is on file with the Secretary of State of The Commonwealth of Massachusetts. The Adviser acknowledges that the obligations of or arising out of this Agreement are not binding upon any of the Trust's Trustees, officers, employees, agents or shareholders individually, but are binding solely upon the assets and property of the Trust. If this Agreement is executed by the Trust on behalf of one or more Funds, the Adviser further acknowledges that the assets and liabilities of each Fund are separate and distinct and that the obligations of or arising out of this Agreement concerning a Fund are binding solely upon the assets or property of such Fund and not upon the assets or property of any other Fund.

Article 11. Definitions and Interpretations. The terms "specifically approved at least annually," "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, and shall be construed in a manner consistent with, the Investment Company Act of 1940 and the rules and regulations promulgated thereunder. Any question of interpretation of any term or provision of this Agreement having a counterpart in or otherwise derived from a term or provision of the Investment Company Act of 1940, the Investment Advisers Act of 1940, the Securities Act of 1933, or the Securities Exchange Act of 1934 (collectively, the "Federal Securities Acts") shall be resolved by reference to such term or provision of the Federal Securities Acts and to interpretations thereof, if any, by United States

6

federal courts or, in the absence of any controlling decisions of any such court, by rules or regulations of the Securities and Exchange Commission. Where the effect of a requirement of the Federal Securities Acts reflected in any provision of this Agreement is revised by rule or regulation of the Securities and Exchange Commission, such provisions shall be deemed to incorporate the effect of such rule or regulation.

Article 12. Record Keeping. The Adviser will maintain records in a form acceptable to the Trust and in compliance with the rules and regulations 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 Trust and will be available for inspection and use by the Trust.

Article 13. Miscellaneous. (a) This Agreement contains the entire understanding and agreement of the parties with respect to the subject matter hereof.

(b) Headings in this Agreement are for ease of reference only and shall not constitute a part of the Agreement.

(c) Should any portion of this Agreement for any reason be held void in law or equity, the remainder of the Agreement shall be construed to the extent possible as if such voided portion had never been contained herein.

(d) This Agreement shall be governed by the laws of the Commonwealth of Massachusetts, without giving effect to the choice of laws provisions thereof, except that questions of interpretation shall be resolved in accordance with the provisions of Article 11 above.

7

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, all as of the day and year first above written. The undersigned officer of the Trust has executed this Agreement not individually, but as an officer under the Declaration and the obligations of this Agreement are not binding upon any of the Trustees, officers or shareholders of a Fund, individually, but bind only the trust estate.
