(1) In no event will the aggregate initial offering price of all securities
issued from time to time pursuant to this Registration Statement exceed
$1,000,000,000 or the equivalent thereof in one or more foreign currencies,
foreign currency units, or composite currencies. If Debt Securities are issued
at original issue discount, State Street Corporation may issue such higher
principal amount as may be sold for an initial public offering price of up to
$1,000,000,000 (less the dollar amount of any securities previously issued
hereunder), or the equivalent thereof in one or more foreign currencies, foreign
currency units, or composite currencies. Pursuant to Rule 429 under the
Securities Act of 1933, $200,000,000 of debt securities and preferred stock are
being carried forward from Registration Statement No. 333-49143 for inclusion in
the Prospectus filed herewith. The aggregate amount of the Common Stock issued
hereunder is further limited to that which is permissible under Rule 415(a)(4)
under the Securities Act of 1933. The securities registered hereunder may be
sold separately or as units with other securities registered hereunder.
(2) The proposed maximum offering price per unit will be determined from time to
time by the Registrant in connection with the issuance by the Registrant of the
securities registered hereunder.
(3) The proposed maximum aggregate offering price has been estimated solely for
the purpose of calculating the registration fee pursuant to Rule 457(o) under
the Securities Act of 1933. A registration fee of $68,966 has been previously
paid with respect to the debt securities and preferred stock being carried
forward from Registration Statement No. 333-49143.
(4) Subject to note (1) above, there is being registered hereunder an
indeterminate principal amount of Debt Securities as may be sold, from time to
time at indeterminate prices, by the Registrant.
(5) Subject to note (1) above, there is being registered hereunder an
indeterminate number of shares of Preferred Stock as may be sold, from time to
time at indeterminate prices, by the Registrant.
(6) Subject to note (1) above, there is being registered hereunder an
indeterminate number of Depositary Shares to be evidenced by Depositary Receipts
issued pursuant to a Deposit Agreement. In the event the Registrant elects to
offer to the public fractional interest in shares of Preferred Stock registered
hereunder, Depositary Receipts will be distributed to those persons purchasing
such fractional interests and the shares of Preferred Stock will be issued to
the Depositary under the Deposit Agreement.
(7) Subject to note (1) above, there is being registered hereunder an
indeterminate number of shares of Common Stock as may be sold, from time to time
at indeterminate prices, by the Registrant.
(8) Subject to note (1) above, there is being registered hereunder an
indeterminate amount and number of Warrants, representing rights to purchase
Debt Securities, Preferred Stock or Common Stock registered hereunder.
(9) Subject to note (1) above, there is being registered hereunder an
indeterminate number of Capital Securities of State Street Capital Trust II,
State Street Capital Trust III and State Street Capital Trust IV and an
indeterminate principal amount of Junior Subordinated Deferrable Interest
Debentures. Junior Subordinated Deferrable Interest Debentures may be issued and
sold to State Street Capital Trust II, State Street Capital Trust III or State
Street Capital Trust IV. Such Junior Subordinated Deferrable Interest Debentures
may later be distributed to the holders of Capital Securities upon termination
of State Street Capital Trust II, State Street Capital Trust III or State Street
Capital Trust IV and the distribution of assets thereof.
(10) Includes the obligations of State Street Corporation under (i) the Amended
Trust Agreement of each of State Street Capital Trust II and State Street
Capital Trust III and The Trust Agreement of State Street Capital Trust IV, (ii)
the Guarantees issued with respect to the Capital Securities issued by such
Trusts, (iii) the Junior Subordinated Deferrable Interest Debentures purchased
by such Trust and the related Indenture, including the agreement of State Street
Corporation (contained in each Amended and Restated Trust Agreement contained in
the Supplemental Indenture) to pay all trust obligations other than the Capital
Securities and the Common Securities, all as described in the Base Prospectus
and the Prospectus Supplement included in this Registration Statement. No
separate consideration will be received for these obligations or for the
Guarantees.
(11) Not applicable pursuant to General Instruction II.D. of Form S-3.

                             ----------------------

This Registration Statement, which is a new Registration Statement, also
constitutes Post-Effective Amendment No. 1 to Registration Statement No.
333-49143 of State Street Corporation which was declared effective on April 15,
1998. Such Post-Effective Amendment shall hereafter become effective
concurrently with the effectiveness of this Registration Statement and in
accordance with Section 8(c) of the Securities Act of 1933. Pursuant to Rule 429
under the Securities Act of 1933, the Prospectus filed as part of this
Registration Statement also constitutes a Prospectus for Registration Statement
No. 333-49143; the $200,000,000 aggregate amount of debt securities and
preferred


stock remaining unsold from Registration Statement No. 333-49143 will be
combined with the Capital Securities, Common Stock, Debt Securities, Preferred
Stock and Guarantees to be registered pursuant to this Registration Statement to
enable State Street Corporation to offer an aggregate amount of $1,000,000,000
of any combination of its Common Stock, Debt Securities and Preferred Stock and
to enable State Street Capital Trust II, State Street Capital Trust III and
State Street Capital Trust IV to offer an aggregate amount of $1,000,000,000 of
Capital Securities pursuant to this combined Prospectus.

The Registrant hereby amends this Registration Statement on such date or dates
as may be necessary to delay its effective date until the Registrant shall file
a further amendment which specifically states that this Registration Statement
shall thereafter become effective in accordance with Section 8(a) of the
Securities Act of 1933 or until this Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to said Section 8(a), may determine.

process. Under this shelf process, we may from time to time sell any combination
of the debt securities or warrants described in this prospectus in one or more
offerings up to a total dollar amount of $1,000,000,000. We may also sell other

provides you with a general description of the debt securities or warrants we
may offer. Each time we sell debt securities or warrants, we will provide a
prospectus supplement that will contain specific information about the terms of
that offering. The prospectus supplement may also add, update or change
information contained in this prospectus. You should read both this prospectus

under the heading "Where You Can Find More Information."

      Unless otherwise indicated or unless the context requires otherwise, all
references in this prospectus to "STATE STREET," "WE," "US," "OUR" or similar

      These forward-looking statements involve risks and uncertainties. Actual
results may differ materially from those contemplated by the forward-looking

o     global and regional economic factors and changes or potential changes in
      laws and regulations affecting our business, including volatile currencies
      and changes in monetary policy, and social and political instability,
      could affect results of operations;

o     market interest rate levels, the shape of the yield curve and the
      direction of interest rate changes affect net interest revenue and
      fiduciary compensation from securities lending;

o     the degree of volatility in foreign exchange rates may affect the amount
      of foreign exchange trading revenue;

o     the pace of pension reform and resulting programs including public and
      private pension schemes may affect the pace of revenue growth;

o     future prices that we are able to obtain for our products may increase or
      decrease from current levels depending upon demand, our competitors'
      activities and the introduction of new products into the marketplace;

o     the pace at which existing and new customers use additional services and
      assign additional assets to us for management or custody will affect
      future results;

o     changes in business mix, including the mix of U.S. and non-U.S. business,
      may affect future results;

o     technological change may be more difficult or expensive then anticipated;

                            STATE STREET CORPORATION

      We are a bank holding company organized under the laws of the Commonwealth
of Massachusetts and a leading provider of services to institutional investors
and investment managers worldwide. We were organized in 1970 and conduct our
business principally through our subsidiary, State Street Bank and Trust
Company, "STATE STREET BANK," which traces its beginnings to the founding of
Union Bank in 1792. The charter under which State Street Bank now operates was
authorized by a special act of the Massachusetts Legislature in 1891, and its
present name was adopted in 1960. Our executive offices are located at 225
Franklin Street, Boston, Massachusetts 02110 (telephone (617) 786-3000).

                CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES

      Our consolidated ratios of earnings to fixed charges were as follows for
the five most recent fiscal years:

                                               Year Ended December 31,

                                 USE OF PROCEEDS

      We intend to use the net proceeds from the sale of the securities for
general corporate purposes unless otherwise indicated in the prospectus
supplement or term sheet relating to a specific issue of securities. Our general
corporate purposes may include extending credit to, or funding investments in,
our subsidiaries. The precise amounts and the timing of our use of the net
proceeds will depend upon our subsidiaries' funding requirements and the
availability of other funds. Until we use the net proceeds from the sale of any
of our securities for general corporate purposes, we will use the net proceeds
to reduce our short-term indebtedness or for temporary investments. We expect
that we will, on a recurrent basis, engage in additional financings as the need
arises to finance our growth, through acquisitions or otherwise, or to fund our
subsidiaries. We and State Street Bank regularly investigate possible
acquisitions.

                         DESCRIPTION OF DEBT SECURITIES

      The senior debt securities will be issued under an indenture dated as of
August 2, 1993, the "SENIOR INDENTURE," between us and U.S. Bank Trust National
Association, as successor senior trustee. The subordinated debt securities
(other than the junior subordinated debentures) will be issued under an
indenture that is expected to be entered into between us and U.S. Bank Trust
National Association, as subordinated trustee, the "SUBORDINATED INDENTURE." A
copy of each indenture is an exhibit to the registration statement that contains
this prospectus.

      The following summaries of all material terms of the indentures are not
complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the respective indentures, including the definitions
of terms. The following summaries describe the general terms and provisions of
the debt securities to be offered by any prospectus supplement. The particular
terms of the debt securities offered by any prospectus supplement and the
extent, if any, to which these general provisions may apply to the debt
securities so offered, will be described in the prospectus supplement relating
to such offered securities.

      The senior debt securities will be unsecured and will rank equally with
all other unsecured and unsubordinated indebtedness of State Street. The
subordinated debt securities will be unsecured and will be subordinated to all
existing and future senior indebtedness and other financial obligations of State
Street as described under


                                       -7-


"Subordinated Debt Securities -- Subordination" beginning on page 13. Because
we are a holding company, our rights and the rights of our creditors, including
the holders of the debt securities we are offering under this prospectus, to
participate in the assets of any of our subsidiaries upon the subsidiary's
liquidation or reorganization will be subject to the prior claims of the
subsidiary's creditors except to the extent that we may ourselves be a creditor
with recognized claims against the subsidiary. In addition, dividends, loans and
advances from certain of our banking subsidiaries to us and our non-banking
subsidiaries are restricted by federal and state statutes and regulations.

General

      We may issue the debt securities from time to time, without limitation as
to aggregate principal amount and in one or more series. We expect from time to
time to incur additional indebtedness that may be senior to the debt securities.
Neither the indentures nor the debt securities will limit or otherwise restrict
the amount of other indebtedness which may be incurred or other securities which
may be issued by us or our subsidiaries, including indebtedness which may rank
senior to the debt securities. The debt securities will not be secured.

      We may issue debt securities upon the satisfaction of conditions contained
in the indentures. The applicable prospectus supplement will include the terms
of that issue of debt securities, including:

o     the title and series designation;

o     the aggregate principal amount and the limit, if any, on the aggregate
      principal amount or initial public offering price of the debt securities
      which may be issued under the applicable indenture;

o     any fixed or variable interest rate or rates per annum;

o     the date from which any interest shall accrue;

o     any interest payment dates;

o     whether the debt securities are senior or subordinated;

o     the stated maturity date;

o     whether the debt securities are to be issued in global form;

o     any sinking fund requirements;

o     any provisions for redemption, the redemption price and any remarketing
      arrangements;

o     the minimum denominations;

o     whether the debt securities are denominated or payable in United States
      dollars or a foreign currency or units of two or more foreign currencies;

o     the place or places where payments or deliveries on the debt securities
      shall be made and the debt securities may be presented for registration of
      transfer or exchange;

o     whether any of the debt securities will be subject to defeasance in
      advance of the date for redemption or the stated maturity date;

o     if other than the principal amount, the portion of the principal amount of
      the debt securities payable upon acceleration of the maturity of the debt
      securities;


                                       -8-


o     any index used to determine the amount of payment of principal of, and any
      premium and interest on, the debt securities;

o     the person to whom any interest on the debt securities of the series shall
      be payable if other than the registered holder thereof;

o     the manner in which the amount that shall be deemed to be the principal
      amount of the debt securities on or prior to the maturity date shall be
      determined;

o     any additional or different events of default that apply to any debt
      securities of the series and any change in the right of the trustee or the
      required holders of those debt securities to declare the principal thereof
      due and payable;

o     any additional or different covenants that apply to any debt securities of
      the series; and

o     any other terms of the debt securities that are not inconsistent with the
      provisions of the applicable indenture.

      Please see the accompanying prospectus supplement or the terms sheet you
have received or will receive for the terms of the specific debt securities we
are offering. We may deliver this prospectus before or concurrently with the
delivery of a terms sheet. We may issue debt securities under the indentures
upon the exercise of warrants to purchase debt securities. Please see
"Description of Warrants." Nothing in the indentures or in the terms of the debt
securities will prohibit the issuance of securities representing subordinated
indebtedness that is senior or junior to the subordinated debt securities.

      Prospective purchasers of debt securities should be aware that special
federal income tax, accounting and other considerations may be applicable to
instruments such as the debt securities. The prospectus supplement relating to
an issue of debt securities will describe these considerations, if they apply.

      Debt securities may be issued as "ORIGINAL ISSUE DISCOUNT SECURITIES"
which bear no interest or interest at a rate which at the time of issuance is
below market rates and which will be sold at a substantial discount below their
principal amount. In the event that the maturity of any original issue discount
security is accelerated, the amount payable to the holder of the original issue
discount security upon acceleration will be determined in accordance with the
applicable prospectus supplement, the terms of such security and the relevant
indenture, but will be an amount less than the amount payable at the maturity of
the principal of such original issue discount security. Special federal income
tax and other considerations relating to original issue discount securities will
be described in the applicable prospectus supplement.

      The indentures provide that without the consent of any holders, we and the
trustee may enter into one or more supplemental indentures for certain purposes,
including:

o     to add to our covenants for the benefit of the holders of all or any
      series of debt securities or to surrender any right or power conferred
      upon us in the indentures; and

o     to add any additional events of default, in the case of the senior
      indenture, and events of default or defaults, in the case of the
      subordinated indenture.

      In the event any sinking fund is established for the retirement of debt
securities of any series, we may satisfy all or any part of the sinking fund
payments with debt securities of such series under certain circumstances and to
the extent provided for by the terms of such debt securities.


                                       -9-


      Unless otherwise indicated in the applicable prospectus supplement, the
covenants contained in the indentures and the debt securities will not protect
holders in the event of a sudden decline in our creditworthiness that might
result from a recapitalization, restructuring, or other highly leveraged
transaction.

Registration and Transfer

      Unless otherwise indicated in the applicable prospectus supplement, we
will issue each series of debt securities in registered form only, without
coupons and in denominations of $1,000 or integral multiples thereof. Holders
may present debt securities in registered form for transfer or exchange for
other debt securities of the same series at the office or agency of State Street
maintained for such purpose.

      No service charge will be made for any transfer or exchange of the debt
securities but we may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection with any transfer or exchange.

Payment and Place of Payment

      Unless otherwise indicated in the applicable prospectus supplement, we
will pay principal of and any premium and interest on the debt securities at the
office or agency of State Street maintained for such purpose. However, at our
option, we may pay any interest by check mailed to the holders of registered
debt securities at their registered addresses.

Events of Default

      The following are "events of default" under the senior indenture and
"defaults" under the subordinated indenture with respect to any series of debt
securities:

o     default in the payment of any principal or premium when due;

o     default in the payment of any interest when due, which continues for 30
      days;

o     default in the deposit of any sinking fund payment when due;

o     default in the performance of any other obligation contained in the senior
      indenture for the benefit of debt securities of that series, which
      continues for 60 days after written notice;

o     acceleration of other indebtedness exceeding $20,000,000 of us or of State
      Street Bank, which is not annulled within 30 days after written notice;

o     specified events in bankruptcy, insolvency or reorganization; and

o     any other default or event of default provided with respect to debt
      securities of that series.

      If an event of default under the senior indenture occurs and is continuing
for any series of debt securities, the senior trustee or the holders of at least
25% in aggregate principal amount or issue price of the outstanding securities
of that series may declare the principal amount of all the securities of that
series, or any lesser amount provided for in the debt securities of that series,
to be due and payable or deliverable immediately. At any time after the senior
trustee or the holders have accelerated any series of debt securities, but
before the senior trustee has obtained a judgment or decree for payment of money
due or delivery of the maturity consideration, the holders of a majority in
aggregate principal amount or issue price of outstanding debt securities of that
series may, under certain circumstances, rescind and annul such acceleration.


                                      -10-


      Under the subordinated indenture, an "event of default" is limited to
certain events involving the bankruptcy, insolvency or reorganization of State
Street. The subordinated debt securities will automatically be accelerated upon
the occurrence of an "event of default" resulting from bankruptcy, insolvency or
reorganization. There is no right of acceleration in the case of a default in
the performance of any covenant with respect to the subordinated debt
securities, including the payment of interest and principal or the delivery of
the maturity consideration.

      The holders of a majority in principal amount or aggregate issue price of
the outstanding debt securities of any series may waive an event of default with
respect to that series, except a default:

o     in the payment of any amounts due and payable or deliverable under the
      debt securities of that series; or

o     in an obligation contained in, or a provision of, an indenture which
      cannot be modified under the terms of that indenture without the consent
      of each holder of each series of debt securities affected.

      The holders of a majority in principal amount or issue price of the
outstanding debt securities of a series may direct the time, method and place of
conducting any proceeding for any remedy available to the applicable trustee or
exercising any trust or power conferred on the trustee with respect to debt
securities of that series, provided that any direction is not in conflict with
any rule of law or the indenture. Subject to the provisions of the indenture
relating to the duties of the trustee, before proceeding to exercise any right
or power under the indenture at the direction of the holders, the trustee is
entitled to receive from those holders reasonable security or indemnity against
the costs, expenses and liabilities which might be incurred by it in complying
with any direction.

      A holder of any debt security of any series will have the right to
institute a proceeding with respect to the indenture or for any remedy
thereunder, if:

o     that holder previously gives to the trustee written notice of a continuing
      event of default with respect to debt securities of that series;

o     the holders of not less than 25% in aggregate principal amount or issue
      price of the outstanding debt securities of that series also shall have
      offered the trustee reasonable indemnity and made written request to the
      trustee to institute such proceeding as trustee;

o     the trustee shall not have received from the holders of a majority in
      principal amount or issue price of the outstanding debt securities of that
      series a direction inconsistent with such request; and

o     the trustee shall have failed to institute such proceeding within 60 days.

      However, any holder of a debt security has the absolute right to institute
suit for any defaulted payment after the due dates for payment under that debt
security.

      We are required to furnish to the trustees annually a statement as to the
performance of our obligations under the indentures and as to any default in
such performance.

Modification and Waiver

      Each indenture may be modified and amended by us and the applicable
trustee with the consent of holders of at least 66 2/3% in principal amount or
issue price of each series of debt securities affected. However, without the
consent of each holder of any debt security affected, we may not amend or modify
any indenture to:

o     change the stated maturity date of the principal or any installment of
      principal or interest on, any debt security;


                                      -11-


o     reduce the principal amount or the rate of interest on, or any premium
      payable upon the redemption of, any debt security;

o     reduce the amount of principal of an original issue discount security
      payable upon acceleration of its maturity;

o     change the place or currency of payment of principal of, or any premium or
      interest on, any debt security;

o     impair the right to institute suit for the enforcement of any payment or
      delivery on or with respect to any debt security;

o     in the case of the subordinated indenture, modify the subordination
      provisions in a manner adverse to the holders of the subordinated debt
      securities;

o     reduce the percentage in principal amount of debt securities of any
      series, the consent of whose holders is required to modify or amend the
      indenture or to waive compliance with certain provisions of the indenture;
      or

o     reduce the percentage in principal amount of debt securities of any
      series, the consent of whose holders is required to waive any past
      default.

      The holders of at least a majority in principal amount of the outstanding
debt securities of any series may, with respect to that series, waive past
defaults under the applicable indenture, except as described under "-- Events of
Default" beginning on page 10.

Consolidation, Merger and Sale of Assets

      Unless otherwise indicated in the applicable prospectus supplement, we may
consolidate or merge with or into any other corporation, and we may sell, lease
or convey all or substantially all of our assets to any corporation, provided
that:

o     the resulting corporation, if other than us, is a corporation organized
      and existing under the laws of the United States of America or any U.S.
      state and assumes all of our obligations on the debt securities under the
      indentures;

o     we are not, or any successor corporation, as the case may be, is not,
      immediately after any consolidation or merger, in default under the
      indentures; and

o     certain other conditions are met.

Regarding the Trustee

      U.S. Bank Trust National Association is the trustee under both the senior
indenture and the subordinated indenture. We and certain of our subsidiaries,
including State Street Bank, maintain banking relations with the trustee in the
ordinary course of business.

International Offering

      If specified in the applicable prospectus supplement, we may issue debt
securities outside the United States. Such debt securities may be issued in
bearer form and will be described in the applicable prospectus supplement. In
connection with any offering outside the United States, we will designate paying
agents, registrars or other agents with respect to the debt securities, as
specified in the applicable prospectus supplement.


                                      -12-


      Debt securities issued outside the United States may be subject to certain
selling restrictions which will be described in the applicable prospectus
supplement. These debt securities may be listed on one or more foreign stock
exchanges as described in the applicable prospectus supplement. Special United
States tax and other considerations, if any, applicable to an offering outside
the United States will be described in the applicable prospectus supplement.

Limitation Upon Disposition of Voting Stock or Assets of State Street Bank

      The senior indenture prohibits us and State Street Bank, so long as any of
the senior debt securities are outstanding, from selling or otherwise disposing
of, or granting a security interest in or permitting the issuance of, any voting
stock or any security convertible or exercisable into voting stock of State
Street Bank or any of our subsidiaries that owns voting stock or any security
convertible or exercisable into voting stock of State Street Bank.

      This restriction does not apply to dispositions made by us or any
subsidiary:

o     if such disposition or issuance is for fair market value as determined by
      our Board of Directors; and

o     if after giving effect to such disposition or issuance and any potential
      dilution, we and our wholly-owned subsidiaries will own directly not less
      than 80% of the voting stock of such principal constituent bank or any
      subsidiary which owns a principal constituent bank.

      The subordinated indenture does not contain a similar restriction on our
ability to engage in or permit such transactions to occur.

Defeasance

      We may terminate or "defease" our obligations under the indentures of any
series of debt securities by taking certain steps, including:

o     depositing irrevocably with the trustee as trust funds in trust in each
      case in an amount, in U.S. dollars or U.S. government obligations, which
      through the payment of interest, principal or premium, if any, in respect
      thereof in accordance with their terms will provide an amount sufficient
      to pay the entire amount of the debt securities;

o     delivering an opinion of independent counsel that the holders of the debt
      securities of such series will have no federal income tax consequences as
      a result of such deposit and termination;

o     no event of default under the senior indenture or default under the
      subordinated indenture may exist or be caused by the defeasance; and

o     the defeasance shall not cause an event of default under any of our other
      agreements or instruments.

Subordinated Debt Securities

      The subordinated debt securities will be our direct, unsecured
obligations. Unless otherwise specified in the applicable prospectus supplement,
the subordinated debt securities will rank equally with all of our outstanding
subordinated indebtedness that is not specifically stated to be junior to the
subordinated debt securities.

      Subordination

      The subordinated debt securities will be subordinated in right of payment
to all "senior indebtedness," as defined below. In certain events of insolvency,
payments on the subordinated debt securities will also be effectively
subordinated in right of payment to all "other financial obligations," as
defined on the next page. In certain circumstances relating to our liquidation,
dissolution, winding up, reorganization, insolvency or similar proceedings,


                                      -13-


the holders of all senior indebtedness will first be entitled to receive payment
in full before the holders of the subordinated debt securities will be entitled
to receive any payment on the subordinated debt securities. If, after all
payments have been made to the holders of senior indebtedness, (A) there are
amounts available for payment on the subordinated debt securities and (B) any
person entitled to payment according to the terms of our other financial
obligations, as defined beginning on page 14, has not received full payment,
then amounts available for payments on the subordinated debt securities will
first be used to pay in full such other financial obligations before any payment
may be made on the subordinated debt securities.

      In the event of the acceleration of the maturity of any debt securities,
all senior indebtedness and other financial obligations will have to be repaid
before any payment can be made on the subordinated debt securities.

      In addition, no payment may be made on the subordinated debt securities in
the event:

o     there is a default in any payment or delivery with respect to any senior
      indebtedness; or

o     there is an event of default with respect to any senior indebtedness which
      permits the holders of such senior indebtedness to accelerate the maturity
      of the senior indebtedness.

      By reason of this subordination in favor of the holders of senior
indebtedness, in the event of an insolvency, our creditors who are not holders
of senior indebtedness or the subordinated debt securities may recover less,
proportionately, than holders of senior indebtedness and may recover more,
proportionately, than holders of the subordinated debt securities. By reason of
the obligation of the holders of subordinated debt securities to pay over any
amount remaining after payment of senior indebtedness to persons in respect of
our other financial obligations, in the event of insolvency, holders of our
existing subordinated indebtedness may recover more, ratably, than the holders
of subordinated debt securities.

      Unless otherwise specified in the prospectus supplement relating to the
particular series of subordinated debt securities, "SENIOR INDEBTEDNESS" is
defined in the subordinated indenture as the principal of, premium, if any, and
interest on:

o     all of our "indebtedness" as defined below, except (A) subordinated debt
      securities issued under the subordinated indenture, (B) such indebtedness
      that is expressly stated to be junior in right of payment to the
      subordinated debt securities and (C) indebtedness that is expressly stated
      to rank equal with the subordinated debt securities; and

o     any deferrals, renewals or extensions of any senior indebtedness.

      The term "INDEBTEDNESS" means indebtedness, whether secured or unsecured,
for which we or any corporation that succeeds to our business as permitted under
the subordinated indenture, is liable directly or indirectly by guarantee,
letter of credit, obligation to purchase or otherwise:

o     for borrowed money; or

o     incurred in connection with the acquisition by us of assets other than in
      the ordinary course of business.

      Unless otherwise specified in the prospectus supplement relating to the
particular series of subordinated debt securities offered thereby, "OTHER
FINANCIAL OBLIGATIONS" means:

o     our obligations under direct credit substitutes;

o     our obligations, or any obligation directly or indirectly guaranteed by
      us, for purchased money or funds;


                                      -14-


o     any of our deferred obligations, or any such obligations directly or
      indirectly guaranteed by us, incurred in connection with the acquisition
      by us of assets; and

o     all of our obligations to make payment pursuant to the terms of financial
      instruments, such as: (A) securities contracts and foreign currency
      exchange contracts; (B) derivative instruments, such as swap agreements,
      including interest rate and foreign exchange rate swap agreements, cap
      agreements, floor agreements, collar agreements, interest rate agreements,
      foreign exchange rate agreements, options, commodity futures contracts,
      commodity option contracts; and (C) similar financial instruments, other
      than obligations on account of senior indebtedness and obligations on
      account of indebtedness for money borrowed ranking equal with or
      subordinate to the subordinated debt securities, including our existing
      subordinated indebtedness.

      As of December 31, 1999, we had approximately $2 million in subordinated
debt outstanding and approximately $250 million of senior indebtedness and other
financial obligations outstanding.

      The subordinated indenture does not limit or prohibit the incurrence by us
or any of our subsidiaries, including State Street Bank, of additional senior
indebtedness or other financial obligations, which may include indebtedness that
is senior to the subordinated debt securities, but subordinate to our other
obligations. Any prospectus supplement relating to a particular series of
subordinated debt securities will set forth the aggregate amount of our
indebtedness senior to the subordinated debt securities as of a recent date.

      The subordinated debt securities shall rank equal in right of payment with
each other and with our 7.75% Convertible Subordinated Debentures, "EXISTING
SUBORDINATED INDEBTEDNESS," subject to the obligations of the holders of
subordinated debt securities to pay over amounts remaining after payment of
senior indebtedness to persons in respect of other financial obligations.

      The prospectus supplement may further describe the provisions, if any,
which may apply to the subordination of the subordinated debt securities of a
particular series.

      Restrictive Covenants

      The subordinated indenture does not contain any significant restrictive
covenants. The prospectus supplement relating to a series of subordinated debt
securities may describe certain restrictive covenants, if any, to which we may
be bound under the subordinated indenture.

Governing Law

      Both indentures are, and the senior debt securities and subordinated debt
securities will be, governed by and construed in accordance with the laws of the
state of New York.

                             DESCRIPTION OF WARRANTS

Offered Warrants

      We may issue warrants that are debt warrants or universal warrants. We may
offer warrants separately or together with one or more additional warrants or
debt securities or any combination of those securities in the form of units, as
described in the applicable prospectus supplement. If we issue warrants as part
of a unit, the accompanying prospectus supplement will specify whether those
warrants may be separated from the other securities in the unit prior to the
warrants' expiration date. Universal warrants issued in the United States may
not be so separated prior to the 91st day after the issuance of the unit, unless
otherwise specified in the applicable prospectus supplement.

      Debt Warrants. We may issue, together with debt securities or separately,
warrants for the purchase of debt securities on terms to be determined at the
time of sale. We refer to this type of warrant as a "DEBT WARRANT."


                                      -15-


      Universal Warrants. We may also issue warrants to purchase or sell, on
terms to be determined at the time of sale:

o     securities of an entity not affiliated with us, a basket of those
      securities, an index or indices of those securities or any combination of
      the above;

o     currencies; or

o     commodities.

      We refer to the property in the above clauses as "WARRANT PROPERTY." We
refer to this type of warrant as a "UNIVERSAL WARRANT." We may satisfy our
obligations, if any, with respect to any universal warrants by delivering the
warrant property or, in the case of warrants to purchase or sell securities or
commodities, the cash value of the securities or commodities, as described in
the applicable prospectus supplement.

Significant Provisions of the Warrant Agreements

      We will issue the warrants under one or more warrant agreements to be
entered into between us and a bank or trust company, as warrant agent, in one or
more series, which will be described in the prospectus supplement for the
warrants. The forms of warrant agreements are filed as exhibits to the
registration statement. The following summaries of significant provisions of the
warrant agreements and the warrants are not intended to be comprehensive and
holders of warrants should review the detailed provisions of the relevant
warrant agreement for a full description and for other information regarding the
warrants.

      Modifications Without Consent of Warrantholders

      We and the warrant agent may amend the terms of the warrants and the
warrant certificates without the consent of the holders to:


                                      -17-


o     cure any ambiguity;

o     cure, correct or supplement any defective or inconsistent provision; or

o     amend the terms in any other manner which we may deem necessary or
      desirable and which will not adversely affect the interests of the
      affected holders in any material respect.

      Enforceability of Rights of Warrantholders

      The warrant agents will act solely as our agents in connection with the
warrant certificates and will not assume any obligation or relationship of
agency or trust for or with any holders of warrant certificates or beneficial
owners of warrants. Any holder of warrant certificates and any beneficial owner
of warrants may, without the consent of any other person, enforce by appropriate
legal action, on its own behalf, its right to exercise the warrants evidenced by
the warrant certificates in the manner provided for in that series of warrants
or pursuant to the applicable warrant agreement. No holder of any warrant
certificate or beneficial owner of any warrants will be entitled to any of the
rights of a holder of the debt securities or any other warrant property, if any,
purchasable upon exercise of the warrants, including, without limitation, the
right to receive the payments on those debt securities or other warrant property
or to enforce any of the covenants or rights in the relevant indenture or any
other similar agreement.

      Registration and Transfer of Warrants

      Subject to the terms of the applicable warrant agreement, warrants in
registered, definitive form may be presented for exchange and for registration
of transfer, at the corporate trust office of the warrant agent for that series
of warrants, or at any other office indicated in the prospectus supplement
relating to that series of warrants, without service charge. However, the holder
will be required to pay any taxes and other governmental charges as described in
the warrant agreement. The transfer or exchange will be effected only if the
warrant agent for the series of warrants is satisfied with the documents of
title and identity of the person making the request.

      Governing Law

      The warrants and each warrant agreement will be governed by, and construed
in accordance with, the laws of the State of New York.

                                GLOBAL SECURITIES

General

      The debt securities may be issued in whole or in part in the form of one
or more fully registered global securities, each a "GLOBAL SECURITY," that will
be deposited with, or on behalf of, a depository which, unless otherwise
indicated in the applicable prospectus supplement for such series, will be DTC.
Unless and until it is exchanged in whole or in part for offered securities in
definitive form, a global security may not be transferred except as a whole in
the following manner: (1) by the depository for such global security to a
nominee of such depository or (2) by a nominee of such depository to such
depository or another nominee of such depository or (3) by such depository or
any such nominee to a successor of such depository or a nominee of such
successor or (4) in the manner provided in the final paragraph under this
heading.

      The specific terms of the depository arrangement with respect to any debt
securities will be described in the applicable prospectus supplement. We
anticipate that the following provisions will apply to all depository
arrangements.

      Upon the issuance of a global security with or on behalf of the
depository, the depository for such global security will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the debt


                                      -18-


securities represented by such global security to the accounts of persons that
have accounts with such depository, each such person, a "PARTICIPANT," which may
include Euroclear and Cedel. The accounts to be credited shall be designated by
the dealers, underwriters or agents participating in the distribution of such
debt securities or by us if we have offered and sold such debt securities
directly. Ownership of beneficial interests in a global security will be limited
to participants or persons that may hold interests through participants.

      Ownership of a beneficial interest in such global security will be shown
on, and the transfer of that ownership will be effected only through, records
maintained by the depository for such global security (with respect to interests
of participants) or by participants or persons that hold through participants
(with respect to interests of persons other than participants). The laws of some
states require that certain purchasers of securities take physical delivery of
such securities in definitive form. Such limits and such laws may impair the
ability to own, transfer or pledge beneficial interests in a global security.

      So long as the depository for a global security, or its nominee, is the
holder of such global security, such depository or such nominee, as the case may
be, will be considered the sole owner or holder of the debt securities
represented by such global security for all purposes under the applicable
indenture. Except as set forth below, owners of beneficial interests in a global
security will not be entitled to have debt securities of the series represented
by such global security registered in their names, will not receive or be
entitled to receive physical delivery of offered securities of such series in
definitive form and will not be considered the owners or holders thereof under
the applicable indenture. Accordingly, each person owning a beneficial interest
in a global security must rely on the procedures of the depository for such
global security and, if such person is not a participant, on the procedures of
the participant through which such person owns its interest, to exercise any
rights of a holder under the applicable indenture. We understand that under
existing industry practices, if we request any action of holders or if an owner
of a beneficial interest in a global security desires to give or take any action
which a holder is entitled to give or take under the applicable indenture, the
depository for such global security would authorize the participants holding the
relevant beneficial interest to give or take such action, and such participants
would authorize beneficial owners owning through such participants to give or
take such action or would otherwise act upon the instructions of beneficial
owners holding through them.

      Payments of principal of or premium, if any, and interest, if any, on debt
securities represented by a global security registered in the name of a
depository or its nominee will be made to such depository or its nominee, as the
case may be, as the registered owner or the holder of the global security
representing such debt securities. None of State Street, the trustee for such
offered securities, any paying agent for such offered securities or the
securities registrar, as applicable, will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in a global security for such offered securities
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

      We expect that the depository for any debt securities represented by a
global debt security, upon receipt of any payment of principal, premium or
interest, will credit immediately participants' accounts with payments in
amounts proportionate to their respective beneficial interests in the principal
amount of such global debt security as shown on the records of such depository.
We also expect that payments by participants to owners of beneficial interests
in such global debt security held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such participants.

      No global debt security may be exchanged in whole or in part for debt
securities registered, and no transfer of a global debt security in whole or in
part may be registered, in the name of any person other than the depository for
such global debt security or a nominee thereof unless:

      (a)   such depository has notified us that it is unwilling or unable to
            continue as depository for such global debt security or has ceased
            to be a clearing agency registered under the Exchange Act;


                                      -19-


      (b)   there shall have occurred and be continuing an event of default or a
            default, as the case may be, with respect to such global debt
            security; or

      (c)   there shall exist such circumstances, if any, in addition to or in
            lieu of the foregoing as have been specified for this purpose as
            contemplated by the indentures.

Book-Entry Issuance

      We expect DTC to act as securities depository for all of the debt
securities. The debt securities will be issued only as fully-registered
securities registered in the name of Cede & Co. (DTC's nominee). DTC will thus
be the only registered holder of the debt securities and will be considered the
sole owner of the debt securities for purposes of the declaration. One or more
fully-registered global certificates will be issued for the debt securities,
representing in the aggregate the aggregate principal balance of debt
securities.

      In this prospectus and the accompanying prospectus supplement, for
book-entry debt securities, references to actions taken by debt security holders
will mean actions taken by DTC upon instructions from its participants, and
reference to payments and notices of redemptions to debt security holders will
mean payments and notices of redemption to DTC as the registered holder of the
debt securities for distribution to the participants in accordance with DTC's
procedures.

      DTC is a limited purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants deposit with DTC. DTC also facilitates
the settlement among participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. "DIRECT PARTICIPANTS" include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. DTC is owned by a number of its direct participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain custodial relationships with direct
participants, either directly or indirectly. The rules applicable to DTC and its
participants are on file with the SEC.

      Purchases of debt securities within the DTC system must be made by or
through direct participants, which will receive a credit for the debt securities
on DTC's records. The ownership interest of each actual purchaser of each debt
security, each, a "BENEFICIAL OWNER," is in turn to be recorded on the direct
and indirect participants' records, including Euroclear and Cedel. DTC will
maintain accounts showing the debt security holdings of its participants, and
these participants will in turn maintain accounts showing the debt security
holdings of their customers. Some of these customers may themselves be
securities intermediaries holding debt securities for their customers. Thus,
each beneficial owner of a book-entry debt security will hold that debt security
indirectly through a hierarchy of intermediaries, with DTC at the "top" and the
beneficial owner's own securities intermediary at the "bottom." Beneficial
owners will not receive written confirmation from DTC of their purchases, but
beneficial owners are expected to receive written confirmations providing
details of the transactions, as well as periodic statements of their holdings,
from the direct or indirect participants through which the beneficial owners
purchased debt securities. Transfers of ownership interests in the debt
securities are to be accomplished by entries made on the books of participants
acting on behalf of beneficial owners. Beneficial owners will not receive
certificates representing their ownership interests in debt securities, except
in the event that use of the book-entry system for the debt securities is
discontinued.


                                      -20-


      Transfers between participants will be effected in accordance with DTC's
procedures and will be settled in same-day funds. Transfers between participants
in Euroclear and Cedel will be effected in the ordinary way in accordance with
their respective rules and operating procedures.

      Cross-market transfers between participants, on the one hand, and
Euroclear participants or Cedel participants, on the other hand, will be
effected by DTC in accordance with DTC's rules on behalf of Euroclear or Cedel,
as the case may be, by its respective depository; however, such cross-market
transaction will require delivery of instructions to Euroclear or Cedel, as the
case may be, by the counterparty in such system in accordance with the rules and
procedures and within the established deadlines (Brussels time) of such system.
Euroclear or Cedel, as the case may be, will, if the transaction meets its
settlement requirements, deliver instructions to its respective depository to
take action to effect final settlement on its behalf by delivering or receiving
interests in the debt securities in DTC, and making or receiving payment in
accordance with normal procedures and Cedel participants may not deliver
instructions directly to the depositaries for Euroclear or Cedel.

      Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in a debt security from a participant
in DTC will be credited, and any such crediting will be reported to the relevant
Euroclear participant or Cedel participant, during the securities settlement
processing day (which must be a business day for Euroclear and Cedel, as the
case may be) immediately following the DTC settlement date. Cash received in
Euroclear or Cedel as a result of sales of interests in a debt security by or
through a Euroclear or Cedel Participant to a Participant in DTC will be
received with value on the DTC settlement date but will be available in the
relevant Euroclear or Cedel cash account only as of the business day for
Euroclear or Cedel following the DTC settlement date.

      DTC has no knowledge of the actual beneficial owners of the debt
securities; DTC's records reflect only the identity of the direct participants
to whose accounts such debt securities are credited, which may or may not be the
beneficial owners. The participants will remain responsible for keeping account
of their holdings on behalf of their customers.

      Conveyance of notices and other communications by DTC to direct
participants, by direct participants to indirect participants, and by direct
participants and indirect participants to beneficial owners and the voting
rights of direct participants, indirect participants and beneficial owners will
be governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

      Redemption notices will be sent to Cede & Co. as the registered holder of
the debt securities. If less than all of the debt securities are being redeemed,
DTC's current practice is to determine by lot the amount of the interest of each
direct participant to be redeemed.

      Although voting with respect to the debt securities is limited to the
holders of record of the debt securities, in those instances in which a vote is
required, neither DTC nor Cede & Co. will itself consent or vote with respect to
the debt securities. Under its usual procedures, DTC would mail an omnibus proxy
to the relevant trustee as soon as possible after the record date. Such omnibus
proxy assigns Cede & Co.'s consenting or voting rights to those direct
participants to whose accounts such or debt securities are credited on the
record date (identified in a listing attached to the omnibus proxy).

      Distribution payments on the debt securities will be made by the relevant
trustee to DTC. DTC's practice is to credit direct participants' accounts on the
relevant payment date in accordance with their respective holdings shown on
DTC's records unless DTC has reason to believe that it will not receive payments
on such payment date. Payments by participants to beneficial owners will be
governed by standing instructions and customary practices and will be the
responsibility of such participant and not of DTC, the relevant trustee or State
Street, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of distributions to DTC is the responsibility of the
relevant trustee, and disbursements of such payments to the beneficial owners is
the responsibility of direct and indirect participants.


                                      -21-


      DTC may discontinue providing its services as securities depository with
respect to any of the debt securities at any time by giving reasonable notice to
the relevant trustee and to us. Under such circumstances, in the event that a
successor securities depository is not obtained, definitive certificates
representing such debt securities are required to be printed and delivered.
Additionally, we, at our option, may decide to discontinue use of the system of
book-entry transfers through DTC (or a successor depository). After an event of
default, the holders of a majority in aggregate principal amount of debt
securities may determine to discontinue the system of book-entry transfers
through DTC. In any event, definitive certificates for such debt securities will
be printed and delivered.

      The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we believe to be accurate, but we assume no
responsibility for the accuracy thereof. We have no responsibility for the
performance by DTC or its participants of their respective obligations as
described herein or under the rules and procedures governing their respective
operations.

                              PLAN OF DISTRIBUTION

      We may sell securities:

o     to the public through a group of underwriters managed or co-managed by,
      one or more underwriters, which may be affiliates;

o     through one or more agents, which may be affiliates; or

o     directly to purchasers.

      The distribution of the securities may be effected from time to time in
one or more transactions:

o     at a fixed price, or prices, which may be changed from time to time;

o     at market prices prevailing at the time of sale;

o     at prices related to such prevailing market prices; or

o     at negotiated prices.

      Each prospectus supplement will describe the method of distribution of the
securities and any applicable restrictions.

      The prospectus supplement with respect to the securities of a particular
series will describe the terms of the offering of the securities, including the
following:

o     the name of the agent or the name or names of any underwriters;

o     the public offering or purchase price;

o     any discounts and commissions to be allowed or paid to the agent or
      underwriters;

o     all other items constituting underwriting compensation;

o     any discounts and commissions to be allowed or paid to dealers; and

o     any exchanges on which the securities will be listed.


                                      -22-


      Only the agents or underwriters named in the prospectus supplement are
agents or underwriters in connection with the securities being offered.

      We may agree to enter into an agreement to indemnify the agents and the
several underwriters against certain civil liabilities, including liabilities
under the Securities Act or to contribute to payments the agents or the
underwriters may be required to make.

      If so indicated in the applicable prospectus supplement, we will authorize
underwriters or other persons acting as our agents to solicit offers by certain
institutions to purchase debt securities or warrants from us pursuant to delayed
delivery contracts providing for payment and delivery on the date stated in the
prospectus supplement. Each contract will be for an amount not less than, and
the aggregate amount of securities sold pursuant to such contracts shall not be
less nor more than, the respective amounts stated in the prospectus supplement.
Institutions with whom the contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and other institutions, but
shall in all cases be subject to our approval. Delayed delivery contracts will
not be subject to any conditions except that:

o     the purchase by an institution of the debt securities or warrants covered
      under that contract shall not at the time of delivery be prohibited under
      the laws of the jurisdiction to which that institution is subject; and

o     if the debt securities or warrants are also being sold to underwriters
      acting as principals for their own account, the underwriters shall have
      purchased such debt securities or warrants not sold for delayed delivery.
      The underwriters and other persons acting as our agents will not have any
      responsibility in respect of the validity or performance of delayed
      delivery contracts.

      Certain of the underwriters and their associates and affiliates may be
customers of, have borrowing relationships with, engage in other transactions
with, and/or perform services, including investment banking services, for, us or
one or more of our affiliates in the ordinary course of business.

      Certain of the underwriters may use this prospectus and the accompanying
prospectus supplement for offers and sales related to market-making transactions
in the securities. These underwriters may act as principal or agent in these
transactions, and the sales will be made at prices related to prevailing market
prices at the time of sale.

      The securities will be new issues of securities and will have no
established trading market. The securities may or may not be listed on a
national securities exchange or the Nasdaq National Market. We can make no
assurance as to the liquidity of or the existence of trading markets for any of
the securities.

                             VALIDITY OF SECURITIES

      Unless the applicable prospectus supplement indicates otherwise, certain
legal matters will be passed upon by Ropes & Gray for State Street and for the
underwriters by Cravath, Swaine & Moore. Ropes & Gray will rely as to all
matters of New York law on the opinion of Cravath, Swaine & Moore. Truman S.
Casner, a partner of Ropes & Gray, is a director of State Street. Mr. Casner
owns beneficially a total of 17,204 shares of common stock of State Street.
Ropes & Gray performs services for State Street from time to time.

31, 1999, June 30, 1999, and September 30 1999, and incorporated herein by
reference, states that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on their
report on such information should be restricted considering the limited nature
of the review procedures applied. The independent auditors are not subject to
the liability provisions of Section 11 of the Securities Act of 1933 (the "Act")
for their report on the unaudited interim financial information because that
report is not a "report" or a "part" of the Registration Statement prepared or
certified by the auditors within the meaning of Sections 7 and 11 of the Act.

                              ABOUT THIS PROSPECTUS

      This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission, the "SEC," utilizing a "shelf" registration
process. Under this shelf process, we may from time to time sell any combination
of the common stock, preferred stock or warrants described in this prospectus in
one or more offerings up to a total dollar amount of $1,000,000,000. We may also
sell other securities under the registration statement that will reduce the
total dollar amount of securities that we may sell under this prospectus. This
prospectus provides you with a general description of the common stock,
preferred stock or warrants we may offer. Each time we sell common stock,
preferred stock or warrants, we will provide a prospectus supplement that will
contain specific information about the terms of that offering. The prospectus
supplement may also add, update or change information contained in this
prospectus. You should read both this prospectus and any prospectus supplement
together with the additional information described under the heading "Where You
Can Find More Information."

      Unless otherwise indicated or unless the context requires otherwise, all
references in this prospectus to "STATE STREET," "WE," "US," "OUR" or similar
references mean State Street Corporation.

                           FORWARD-LOOKING STATEMENTS

This prospectus, including information included or incorporated by reference,
contains certain forward-looking statements with respect to our financial
condition, results of operations, plans, objectives, future performance and
business, including, without limitation, statements preceded by, followed by or
that include the words "believes," "expects," "anticipates," "estimates" or
similar expressions.

      These forward-looking statements involve risks and uncertainties. Actual
results may differ materially from those contemplated by the forward-looking
statements due to many factors, including:

o     future revenue may increase or decrease depending upon the extent of
      increases or decreases in cross-border investments made by customers or
      future customers;

o     changes in the savings rate of individuals that are invested in mutual
      funds or in defined contribution plans affect our revenues;

o     fluctuations in worldwide securities market valuations may affect our
      revenues;

o     changes in markets served, including the growth rate of U.S. mutual funds,
      the pace of debt issuance, outsourcing decisions, and mergers,
      acquisitions and consolidations among customers and competitors may affect
      our revenues;

o     global and regional economic factors and changes or potential changes in
      laws and regulations affecting our business, including volatile currencies
      and changes in monetary policy, and social and political instability,
      could affect results of operations;

o     market interest rate levels, the shape of the yield curve and the
      direction of interest rate changes affect net interest revenue and
      fiduciary compensation from securities lending;

o     the degree of volatility in foreign exchange rates may affect the amount
      of foreign exchange trading revenue;

o     the pace of pension reform and resulting programs including public and
      private pension schemes may affect the pace of revenue growth;

o     future prices that we are able to obtain for our products may increase or
      decrease from current levels depending upon demand, our competitors'
      activities and the introduction of new products into the marketplace;

o     the pace at which existing and new customers use additional services and
      assign additional assets to us for management or custody will affect
      future results;

o     changes in business mix, including the mix of U.S. and non-U.S. business,
      may affect future results;

o     technological change may be more difficult or expensive then anticipated;
      and

o     changes may occur in securities markets.


                            STATE STREET CORPORATION

      We are a bank holding company organized under the laws of the Commonwealth
of Massachusetts and a leading provider of services to institutional investors
and investment managers worldwide. We were organized in 1970 and conduct our
business principally through our subsidiary, State Street Bank and Trust
Company, "STATE STREET BANK," which traces its beginnings to the founding of
Union Bank in 1792. The charter under which State Street Bank now operates was
authorized by a special act of the Massachusetts Legislature in 1891, and its
present name was adopted in 1960. Our executive offices are located at 225
Franklin Street, Boston, Massachusetts 02110 (telephone (617) 786-3000).

    CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND PREFERRED DIVIDENDS

      Our consolidated ratios of earnings to fixed charges were as follows for
the five most recent fiscal years:

                                 USE OF PROCEEDS

      We intend to use the net proceeds from the sale of the securities for
general corporate purposes unless otherwise indicated in the prospectus
supplement or term sheet relating to a specific issue of securities. Our general
corporate purposes may include extending credit to, or funding investments in,
our subsidiaries. The precise amounts and the timing of our use of the net
proceeds will depend upon our subsidiaries' funding requirements and the
availability of other funds. Until we use the net proceeds from the sale of any
of our securities for general corporate purposes, we will use the net proceeds
to reduce our short-term indebtedness or for temporary investments. We expect
that we will, on a recurrent basis, engage in additional financings as the need
arises to finance our growth, through acquisitions or otherwise, or to fund our
subsidiaries. We and State Street Bank regularly investigate possible
acquisitions.

DESCRIPTION OF PREFERRED STOCK

      The following summary contains a description of the general terms of the
preferred stock, the "PREFERRED STOCK," that we may issue. Other terms of any
series of preferred stock will be described in the prospectus supplement
relating to that series of preferred stock. The terms of any series of preferred
stock may differ from the terms described below. Certain provisions of the
preferred stock described below and in any prospectus supplement are not
complete. You should refer to our Restated Articles of Incorporation, as
amended, "ARTICLES OF INCORPORATION," and the certificate of designation which
will be filed with the SEC in connection with the offering of the series of
preferred stock.

General

      Our articles of incorporation permit our board of directors to authorize
the issuance of up to 3,500,000 shares of preferred stock, without par value, in
one or more series, without shareholder action. The board of directors can
determine the rights, preferences and limitations of each series. Therefore,
without shareholder approval, our board of directors can authorize the issuance
of preferred stock with voting, conversion and other rights that could dilute
the voting power and other rights of our common stockholders. None of our
preferred stock is currently outstanding.


                                       -7-


      The preferred stock has the terms described below unless otherwise
provided in the prospectus supplement relating to a particular series of the
preferred stock. You should read the prospectus supplement relating to the
particular series of the preferred stock being offered for specific terms,
including:

o     the designation and stated value per share of the preferred stock and the
      number of shares offered;

o     the amount of liquidation preference per share;

o     the price at which the preferred stock will be issued;

o     the dividend rate, or method of calculation, the dates on which dividends
      will be payable, whether dividends will be cumulative or noncumulative
      and, if cumulative, the dates from which dividends will commence to
      accumulate;

o     any redemption or sinking fund provisions;

o     any conversion provisions;

o     whether we have elected to offer depositary shares as described under
      "Description of Depositary Shares;" and

o     any other rights, preferences, privileges, limitations and restrictions on
      the preferred stock.

      The preferred stock will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the prospectus supplement, each series of the
preferred stock will rank equally as to dividends and liquidation rights in all
respects with each other series of preferred stock. The rights of holders of
shares of each series of preferred stock will be subordinate to those of our
general creditors.

      As described under "Description of Depositary Shares," we may, at our
option, with respect to any series of the preferred stock, elect to offer
fractional interests in shares of preferred stock, and provide for the issuance
of depositary receipts representing depositary shares, each of which will
represent a fractional interest in a share of the series of the preferred stock.
The fractional interest will be specified in the prospectus supplement relating
to a particular series of the preferred stock.

Rank

      Any series of the preferred stock will, with respect to the priority of
the payment of dividends and the priority of payments upon liquidation, winding
up and dissolution, rank:

o     senior to all classes of common stock and all equity securities issued by
      us the terms of which specifically provide that the equity securities will
      rank junior to the preferred stock, the "JUNIOR SECURITIES;"

o     equally with all equity securities issued by us the terms of which
      specifically provide that the equity securities will rank equally with the
      preferred stock, the "PARITY SECURITIES;" and

o     junior to all equity securities issued by us the terms of which
      specifically provide that the equity securities will rank senior to the
      preferred stock.

Dividends

      Holders of the preferred stock of each series will be entitled to receive,
when, as and if declared by our board of directors, cash dividends at such rates
and on such dates described in the prospectus supplement. Different series of
preferred stock may be entitled to dividends at different rates or based on
different methods of calculation. The


                                       -8-


dividend rate may be fixed or variable or both. Dividends will be payable to the
holders of record as they appear on our stock books on record dates fixed by our
board of directors, as specified in the applicable prospectus supplement.

      Dividends on any series of the preferred stock may be cumulative or
noncumulative, as described in the applicable prospectus supplement. If our
board of directors does not declare a dividend payable on a dividend payment
date on any series of noncumulative preferred stock, then the holders of that
noncumulative preferred stock will have no right to receive a dividend for that
dividend payment date, and we will have no obligation to pay the dividend
accrued for that period, whether or not dividends on that series are declared
payable on any future dividend payment dates. Dividends on any series of
cumulative preferred stock will accrue from the date we initially issue shares
of such series or such other date specified in the applicable prospectus
supplement.

      No full dividends may be declared or paid or funds set apart for the
payment of any dividends on any parity securities unless dividends have been
paid or set apart for payment on the preferred stock. If full dividends are not
paid, the preferred stock will share dividends pro rata with the parity
securities. No dividends may be declared or paid or funds set apart for the
payment of dividends on any junior securities unless full cumulative dividends
for all dividend periods terminating on or prior to the date of the declaration
or payment will have been paid or declared and a sum sufficient for the payment
set apart for payment on the preferred stock.

      Our ability to pay dividends on our preferred stock is subject to policies
established by the Federal Reserve Board.

Rights Upon Liquidation

      If we dissolve, liquidate or wind up our affairs, either voluntarily or
involuntarily, the holders of each series of preferred stock will be entitled to
receive, before any payment or distribution of assets is made to holders of
junior securities, liquidating distributions in the amount described in the
prospectus supplement relating to that series of the preferred stock, plus an
amount equal to accrued and unpaid dividends and, if the series of the preferred
stock is cumulative, for all dividend periods prior to that point in time. If
the amounts payable with respect to the preferred stock of any series and any
other parity securities are not paid in full, the holders of the preferred stock
of that series and of the parity securities will share proportionately in the
distribution of our assets in proportion to the full liquidation preferences to
which they are entitled. After the holders of preferred stock and the parity
securities are paid in full, they will have no right or claim to any of our
remaining assets.

      Because we are a bank holding company, our rights, the rights of our
creditors and of our stockholders, including the holders of the preferred stock
offered by this prospectus, to participate in the assets of any subsidiary upon
the subsidiary's liquidation or recapitalization may be subject to the prior
claims of the subsidiary's creditors except to the extent that we may ourselves
be a creditor with recognized claims against the subsidiary.

Redemption

      A series of the preferred stock may be redeemable, in whole or in part, at
our option with prior Federal Reserve Board approval. In addition, a series of
preferred stock may be subject to mandatory redemption pursuant to a sinking
fund or otherwise. The redemption provisions that may apply to a series of
preferred stock, including the redemption dates and the redemption prices for
that series, will be described in the prospectus supplement.

      In the event of partial redemptions of preferred stock, whether by
mandatory or optional redemption, our board of directors will determine the
method for selecting the shares to be redeemed, which may be by lot or pro rata
or by any other method determined to be equitable.

      On or after a redemption date, unless we default in the payment of the
redemption price, dividends will cease to accrue on shares of preferred stock
called for redemption. In addition, all rights of holders of the shares will
terminate except for the right to receive the redemption price.


                                       -9-


      Unless otherwise specified in the applicable prospectus supplement for any
series of preferred stock, if any dividends on any other series of preferred
stock ranking equally as to payment of dividends and liquidation rights with
such series of preferred stock are in arrears, no shares of any such series of
preferred stock may be redeemed, whether by mandatory or optional redemption,
unless all shares of preferred stock are redeemed, and we will not purchase any
shares of such series of preferred stock. This requirement, however, will not
prevent us from acquiring such shares pursuant to a purchase or exchange offer
made on the same terms to holders of all such shares outstanding.

      Under current regulations, bank holding companies may exercise an option
to redeem shares of preferred stock included as Tier 1 capital, or exchange the
preferred stock for debt securities, without the prior approval of the Federal
Reserve Board, if the bank holding company will remain well capitalized,
received a composite rating of 1 or 2 on its most recent BOPEC inspection and is
not the subject of any unresolved supervisory issues.

Voting Rights

      Unless otherwise described in the applicable prospectus supplement,
holders of the preferred stock will have no voting rights except as set forth
below or as otherwise required by law or in our articles of organization.

      Under regulations adopted by the Federal Reserve Board, if the holders of
any series of the preferred stock are or become entitled to vote for the
election of directors because dividends on such series are in arrears, such
series may then be deemed a "class of voting securities" and a holder of 25% or
more of such series, or a holder of 5% or more if it otherwise exercises a
"controlling influence" over us, may then be subject to regulation as a bank
holding company in accordance with the Bank Holding Company Act. In addition, at
such time as such series is deemed a class of voting securities, (a) any other
bank holding company may be required to obtain the approval of the Federal
Reserve Board to acquire or retain 5% or more of that series and (b) any person
other than a bank holding company may be required to obtain the approval of the
Federal Reserve Board to acquire or retain 10% or more of that series.

Conversion Rights

      Shares of preferred stock of any series may not be exchanged for or
converted, mandatorily or otherwise, into shares of common stock, but may be
exchanged for or converted, mandatorily or otherwise, into shares of another
series of preferred stock.

Exchangeability

      The holders of shares of preferred stock of any series may be required at
any time or at maturity to exchange those shares for our debt securities. The
applicable prospectus supplement will specify the terms of any such exchange.

Transfer Agent and Registrar

      Unless otherwise indicated in the applicable prospectus supplement,
Equiserve Limited Partnership, an affiliate of State Street, will be the
transfer agent, dividend and redemption price disbursement agent and registrar
for shares of each series of the preferred stock.

                        DESCRIPTION OF DEPOSITARY SHARES

General

      We may, at our option, elect to offer fractional shares of preferred
stock, "DEPOSITARY SHARES," rather than full shares of preferred stock. If we
do, we will issue to the public receipts, called "DEPOSITARY


                                      -10-


RECEIPTS," for depositary shares, each of which will represent a fraction, to be
described in the prospectus supplement, of a share of a particular series of
preferred stock.

      The shares of any series of preferred stock represented by depositary
shares will be deposited under a deposit agreement, the "DEPOSIT AGREEMENT,"
between us and the depositary named in the prospectus supplement, the
"DEPOSITARY." Subject to the terms of the deposit agreement, each owner of a
depositary share will be entitled, in proportion to the applicable fractional
interest in a share of preferred stock represented by the depositary share, to
all the rights and preferences of the preferred stock represented by the
depositary share. Those rights include dividend, voting, redemption, conversion
and liquidation rights.

      The following summary of certain provisions of the deposit agreement is
not complete and is subject to, and is qualified in its entirety by reference
to, all the provisions of the deposit agreement. Whenever particular sections of
the deposit agreement are referred to, it is intended that the sections shall be
incorporated by reference in this prospectus. You should read copies of the
forms of deposit agreement and depositary receipt filed as exhibits to the
registration statement which contains this prospectus.

Dividends and Other Distributions

      The depositary will distribute all cash dividends or other cash
distributions received in respect of the preferred stock to the record holders
of depositary shares in proportion to the numbers of depositary shares owned by
those holders.

      If there is a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary shares,
unless the depositary determines that it is not feasible to make the
distribution. If this occurs, the depositary may, with our approval, sell the
property and distribute the net proceeds from the sale to the holders.

Withdrawal of Stock

      Unless the related depositary shares have been previously called for
redemption, upon surrender of the depositary receipts at the office of the
depositary, the holder of the depositary shares will be entitled to delivery, at
the office of the depositary to or upon his or her order, of the number of whole
shares of the preferred stock and any money or other property represented by the
depositary shares. If the depositary receipts delivered by the holder evidence a
number of depositary shares in excess of the number of depositary shares
representing the number of whole shares of preferred stock to be withdrawn, the
depositary will deliver to the holder at the same time a new depositary receipt
evidencing the excess number of depositary shares. In no event will the
depositary deliver fractional shares of preferred stock upon surrender of
depositary receipts.

Redemption of Depositary Shares

      Whenever we redeem shares of preferred stock held by the depositary, the
depositary will redeem as of the same redemption date the number of depositary
shares representing shares of the preferred stock so redeemed, so long as we
have paid in full to the depositary the redemption price of the preferred stock
to be redeemed plus an amount equal to any accumulated and unpaid dividends on
the preferred stock to the date fixed for redemption. The redemption price per
depositary share will be equal to the redemption price and any other amounts per
share payable on the preferred stock multiplied by the fraction of a share of
preferred stock represented by one depositary share. If less than all the
depositary shares are to be redeemed, the depositary shares to be redeemed will
be selected by lot or pro rata as may be determined by the depositary.

      After the date fixed for redemption, depositary shares called for
redemption will no longer be deemed to be outstanding and all rights of the
holders of depositary shares will cease, except the right to receive the moneys


                                      -11-


payable upon redemption and any money or other property to which the holders of
the depositary shares were entitled upon redemption upon surrender to the
depositary of the depositary receipts evidencing the depositary shares.

Voting the Preferred Stock

      Upon receipt of notice of any meeting at which the holders of the
preferred stock are entitled to vote, the depositary will mail the information
contained in the notice of meeting to the record holders of the depositary
receipts relating to that preferred stock. The record date for the depositary
receipts relating to the preferred stock will be the same date as the record
date for the preferred stock. Each record holder of the depositary shares on the
record date will be entitled to instruct the depositary as to the exercise of
the voting rights pertaining to the number of shares of preferred stock
represented by that holder's depositary shares. The depositary will endeavor,
insofar as practicable, to vote the number of shares of preferred stock
represented by the depositary shares in accordance with those instructions, and
we will agree to take all action which may be deemed necessary by the depositary
in order to enable the depositary to do so. The depositary will not vote any
shares of preferred stock except to the extent it receives specific instructions
from the holders of depositary shares representing that number of shares of
preferred stock.

Amendment and Termination of the Deposit Agreement

      The form of depositary receipt evidencing the depositary shares and any
provision of the deposit agreement may at any time be amended by agreement
between us and the depositary. However, any amendment that materially and
adversely alters the rights of the existing holders of depositary receipts will
not be effective unless it has been approved by the holders of at least a
majority of the depositary shares then outstanding.

      We or the depositary may terminate the deposit agreement only if:

o     all outstanding depositary shares have been redeemed; or

o     there has been a final distribution in respect of the preferred stock in
      connection with our liquidation, dissolution or winding up and the
      distribution has been distributed to the holders of depositary receipts.

Charges of Depositary

      We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the depositary arrangements. We will pay charges of
the depositary in connection with the initial deposit of the preferred stock and
any redemption of the preferred stock. Holders of depositary receipts will pay
other transfer and other taxes and governmental charges and such other charges
as are expressly provided in the deposit agreement to be for their accounts.

Resignation and Removal of Depositary

      The depositary may resign at any time by delivering to us notice of its
election to do so, and we may remove the depositary at any time. Any resignation
or removal of the depositary will take effect upon our appointment of a
successor depositary and its acceptance of such appointment. The successor
depositary must be appointed within 60 days after delivery of the notice of
resignation or removal and must be a bank or trust company having its principal
office in the United States and having a combined capital and surplus of at
least $50,000,000.

Notices

      The depositary will forward to holders of depositary receipts all notices,
reports and other communications, including proxy solicitation materials
received from us, which are delivered to the depositary and which we are
required to furnish to the holders of the preferred stock.


                                      -12-


Limitation of Liability

      Neither we nor the depositary will be liable if either of us is prevented
or delayed by law or any circumstance beyond our control in performing our
obligations under the deposit agreement. Our obligations and those of the
depositary under the deposit agreement will be limited to performance in good
faith of our and their duties thereunder. We and the depositary will not be
obligated to prosecute or defend any legal proceeding in respect of any
depositary shares or preferred stock unless satisfactory indemnity is furnished.
We and the depositary may rely upon written advice of counsel or accountants, on
information provided by persons presenting preferred stock for deposit, holders
of depositary receipts or other persons believed to be competent and on
documents believed to be genuine.

Inspection of Books

      Any record holder of depositary shares who has been a holder for at least
six months or who holds at least five percent of our outstanding shares of
capital stock will be entitled to inspect the transfer books relating to the
depositary shares and the list of record holders of depositary shares upon
certification to the depositary that the holder is acting in good faith and that
the inspection is for a proper purpose.

                           DESCRIPTION OF COMMON STOCK

General

      We have 250,000,000 shares of common stock, $1.00 par value per share,
authorized, of which 159,590,000 shares were outstanding as of December 31,
1999.

      Holders of our common stock are entitled to receive dividends when, as and
if declared by our board of directors out of any funds legally available for
dividends. Holders of our common stock are also entitled, upon our liquidation,
and after claims of creditors and preferences of preferred stock, and any other
class or series of preferred stock outstanding at the time of liquidation, to
receive pro rata our net assets. We pay dividends on our common stock only if we
have paid or provided for all dividends on our outstanding series of preferred
stock, for the then current period and, in the case of any cumulative preferred
stock, all prior periods.

      Our preferred stock has, or upon issuance will have, preference over our
common stock with respect to the payment of dividends and the distribution of
assets in the event of our liquidation or dissolution. Our preferred stock also
has such other preferences as may be fixed by our board of directors.

      Holders of our common stock are entitled to one vote for each share that
they hold and are vested with all of the voting power except as our board of
directors has provided, or may provide in the future, with respect to preferred
stock or any other class or series of preferred stock that the board of
directors may hereafter authorize. See "Description of Preferred Stock" and
"Description of Existing Preferred Stock." Shares of our common stock are not
redeemable, and have no subscription, conversion or preemptive rights.

      The affirmative vote of not less than 80% of our outstanding voting stock,
voting separately as a class, is required for certain business combinations
between us and/or our subsidiaries and persons owning 10% or more of our voting
stock. See "Selected Provisions in our Articles of Incorporation--Business
Combinations With Related Persons."

      Our common stock is listed on the New York Stock Exchange. Outstanding
shares of our common stock are validly issued, fully paid and non-assessable.
Holders of our common stock are not, and will not be, subject to any liability
as stockholders.

Shareholders' Rights Plan


                                      -13-


      In 1988, State Street declared a dividend of one preferred share purchase
right for each outstanding share of common stock pursuant to a shareholders'
Rights Agreement. On June 18, 1998, State Street adopted an amendment to the
Rights Agreement and has restated the Rights Agreement. Under the Amended and
Restated Rights Agreement, a right may be exercised, under certain conditions,
to purchase one four-hundredths share of a series of participating preferred
stock at an exercise price of $265, subject to adjustment. The rights become
exercisable if a party acquires or obtains the right to acquire 10% or more of
State Street's common stock or after commencement or public announcement of an
offer for 10% or more of State Street's common stock. When exercisable, under
certain conditions, each right also entitles the holder thereof to purchase
shares of common stock, of either State Street or of the acquiror, having a
market value of two times the then current exercise price of that right.

      The rights expire in September 2008, and may be redeemed at a price of
$.0025 per right at any time prior to expiration or the acquisition of 10% of
State Street's common stock. Under certain circumstances, the rights may be
redeemed after they become exercisable and may be subject to automatic
redemption.

Transfer Agent and Registrar

      The transfer agent and registrar for our common stock is Equiserve Limited
Partnership, an affiliate of State Street.

Restrictions on Ownership

      The Bank Holding Company Act requires any "bank holding company," as
defined in the Bank Holding Company Act, to obtain the approval of the Federal
Reserve Board prior to the acquisition of 5% or more of our common stock. Any
person, other than a bank holding company, is required to obtain prior approval
of the Federal Reserve Board to acquire 10% or more of our common stock under
the Change in Bank Control Act. Any holder of 25% or more of our common stock,
or a holder of 5% or more if such holder otherwise exercises a "controlling
influence" over us, is subject to regulation as a bank holding company under the
Bank Holding Company Act.

                             DESCRIPTION OF WARRANTS

      We may issue warrants to purchase preferred stock or common stock.
Warrants may be issued independently or together with preferred stock or common
stock and may be attached to or separate from any preferred stock or common
stock. Each series of warrants will be issued under a separate warrant agreement
to be entered into between us and a warrant agent. The warrant agent will act
solely as our agent in connection with the warrants and will not assume any
obligation or relationship of agency or trust for or with any holders or
beneficial owners of warrants. Below is a description of certain general terms
and provisions of the warrants that we may offer. Further terms of the warrants
and the applicable warrant agreement will be described in the prospectus
supplement.

      The prospectus supplement relating to a particular issue of warrants will
describe the terms of the warrants, which may include the following:

o     the title of the warrants;

      purchasable upon exercise of the warrants;

o     if applicable, the designation and terms of the preferred stock or common
      stock with which the warrants are issued and the number of warrants issued
      with each security;


                                      -14-


o     if applicable, the date from and after which the warrants and the related
      preferred stock or common stock will be separately transferable;

o     the number of shares of preferred stock or common stock purchasable upon
      exercise of a warrant and the price at which those shares may be
      purchased;

o     the date on which the right to exercise the warrants shall begin and the
      date on which such right shall expire;

o     if applicable, the minimum or maximum amount of the warrants that may be
      exercised at any one time;

o     information with respect to book-entry procedures, if any;

o     the currency or currency units in which the offering price, if any, and
      the exercise price are payable;

o     if applicable, a discussion of material United States Federal income tax
      considerations;

o     the antidilution provisions of the warrants, if any;

o     any redemption or call provisions; and

o     any additional terms of the warrants, including terms, procedures, and
      limitations relating to the exchange and exercise of the warrants.

                              PLAN OF DISTRIBUTION

      We may sell securities:

o     to the public through a group of underwriters managed or co-managed by,
      one or more underwriters, which may be affiliates;

o     through one or more agents, which may be affiliates; or

o     directly to purchasers.

      The distribution of the securities may be effected from time to time in
one or more transactions:

o     at a fixed price, or prices, which may be changed from time to time;

o     at market prices prevailing at the time of sale;

o     at prices related to such prevailing market prices; or

o     at negotiated prices.

      Each prospectus supplement will describe the method of distribution of the
securities and any applicable restrictions.

      The prospectus supplement with respect to the securities of a particular
series will describe the terms of the offering of the securities, including the
following:

o     the name of the agent or the name or names of any underwriters;


                                      -15-


o     the public offering or purchase price;

o     any discounts and commissions to be allowed or paid to the agent or
      underwriters;

o     all other items constituting underwriting compensation;

o     any discounts and commissions to be allowed or paid to dealers; and

o     any exchanges on which the securities will be listed.

      Only the agents or underwriters named in the prospectus supplement are
agents or underwriters in connection with the securities being offered.

      We may agree to enter into an agreement to indemnify the agents and the
several underwriters against certain civil liabilities, including liabilities
under the Securities Act or to contribute to payments the agents or the
underwriters may be required to make.

      If so indicated in the applicable prospectus supplement, we will authorize
underwriters or other persons acting as our agents to solicit offers by certain
institutions to purchase securities from us pursuant to delayed delivery
contracts providing for payment and delivery on the date stated in the
prospectus supplement. Each contract will be for an amount not less than, and
the aggregate amount of securities sold pursuant to such contracts shall not be
less nor more than, the respective amounts stated in the prospectus supplement.
Institutions with whom the contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and other institutions, but
shall in all cases be subject to our approval. Delayed delivery contracts will
not be subject to any conditions except that:

o     the purchase by an institution of the securities covered under that
      contract shall not at the time of delivery be prohibited under the laws of
      the jurisdiction to which that institution is subject; and

o     if the securities are also being sold to underwriters acting as principals
      for their own account, the underwriters shall have purchased such
      securities not sold for delayed delivery. The underwriters and other
      persons acting as our agents will not have any responsibility in respect
      of the validity or performance of delayed delivery contracts.

      Certain of the underwriters and their associates and affiliates may be
customers of, have borrowing relationships with, engage in other transactions
with, and/or perform services, including investment banking services, for, us or
one or more of our affiliates in the ordinary course of business.

      Certain of the underwriters may use this prospectus and the accompanying
prospectus supplement for offers and sales related to market-making transactions
in the securities. These underwriters may act as principal or agent in these
transactions, and the sales will be made at prices related to prevailing market
prices at the time of sale.

      The securities will be new issues of securities and will have no
established trading market. The securities may or may not be listed on a
national securities exchange or the Nasdaq National Market. We can make no
assurance as to the liquidity of or the existence of trading markets for any of
the securities.

                             VALIDITY OF SECURITIES

      Unless the applicable prospectus supplement indicates otherwise, certain
legal matters will be passed upon by Ropes & Gray for State Street and for the
underwriters by Cravath, Swaine & Moore. Ropes & Gray will rely as to all
matters of New York law on the opinion of Cravath, Swaine & Moore. Truman S.
Casner, a partner of Ropes & Gray, is a director of State Street. Mr. Casner
owns beneficially a total of 17,204 shares of common stock of State Street.
Ropes & Gray performs services for State Street from time to time.

                                     EXPERTS

      The consolidated financial statements of State Street Corporation
incorporated by reference in State Street Corporation's Annual Report (Form
10-K) for the year ended December 31, 1999, have been audited by Ernst & Young
LLP, independent auditors, as set forth in their report thereon incorporated by
reference therein and incorporated herein by reference. Such consolidated
financial statements are incorporated herein by reference in reliance upon such
report given on the authority of such firm as experts in accounting and
auditing.

      With respect to the unaudited condensed consolidated interim financial
information for the three-month periods ended March 31, 1999 and March 31, 1998,
the six-month periods ended June 30, 1999 and June 30, 1998, and the nine-month
periods ended September 30, 1999 and September 30, 1998, incorporated by
reference in this Prospectus, Ernst & Young LLP have reported that they have
applied limited procedures in accordance with professional standards for a
review of such information. However, their separate report, included in State
Street Corporation's Quarterly Reports on Form 10-Q for the quarters ended March
31, 1999, June 30, 1999, and September 30 1999, and incorporated herein by
reference, states that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on their
report on such information should be restricted considering the limited nature
of the review procedures applied. The independent auditors are not subject to
the liability provisions of Section 11 of the Securities Act of 1933 (the "Act")
for their report on the unaudited interim financial information because that
report is not a "report" or a "part" of the Registration Statement prepared or
certified by the auditors within the meaning of Sections 7 and 11 of the Act.

                                   THE TRUSTS:

      The trusts are Delaware business trusts. Each trust may from time to time:

o     sell capital securities representing undivided beneficial interests in the
      trust to the public;

o     sell common securities representing undivided beneficial interests in the
      trust to State Street Corporation;

      junior subordinated debentures of State Street Corporation; and

o     distribute the cash payments it receives on the junior subordinated
      debentures it owns to the holders of the capital and common securities.

                                 DISTRIBUTIONS:

o     For each capital security that you own, you will receive cumulative cash
      distributions at a rate set forth in the accompanying prospectus
      supplement on the liquidation amount of the preferred security. The
      liquidation amount per capital security will be set forth in the
      accompanying prospectus supplement.

                            STATE STREET CORPORATION:

      State Street Corporation will fully and unconditionally guarantee the
payment by the trust of the capital securities based on obligations discussed in
this prospectus. This is called the capital securities guarantee.

                              --------------------

                              ABOUT THIS PROSPECTUS

    This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission, the "SEC," utilizing a "shelf" registration
process. Under this shelf process, we may from time to time sell any combination
of the debt securities or warrants described in this prospectus in one or more
offerings up to a total dollar amount of $1,000,000,000. We may also sell other
securities under the registration statement that will reduce the total dollar
amount of securities that we may sell under this prospectus. This prospectus
provides you with a general description of the debt securities or warrants we
may offer. Each time we sell debt securities or warrants, we will provide a
prospectus supplement that will contain specific information about the terms of
that offering. The prospectus supplement may also add, update or change
information contained in this prospectus. You should read both this prospectus
and any prospectus supplement together with the additional information described
under the heading "Where You Can Find More Information."

    Unless otherwise indicated or unless the context requires otherwise, all
references in this prospectus to "STATE STREET," "WE," "US," "OUR" or similar

    laws and regulations affecting our business, including volatile currencies
    and changes in monetary policy, and social and political instability, could
    affect results of operations;

    of interest rate changes affect net interest revenue and fiduciary
    compensation from securities lending;

    decrease from current levels depending upon demand, our competitors'
    activities and the introduction of new products into the marketplace;

o   the pace at which existing and new customers use additional services and
    assign additional assets to us for management or custody will affect future
    results;

                            STATE STREET CORPORATION

    We are a bank holding company organized under the laws of the Commonwealth
of Massachusetts and a leading provider of services to institutional investors
and investment managers worldwide. We were organized in 1970 and conduct our
business principally through our subsidiary, State Street Bank and Trust
Company, "STATE STREET BANK," which traces its beginnings to the founding of
Union Bank in 1792. The charter under which State Street Bank now operates was
authorized by a special act of the Massachusetts Legislature in 1891, and its
present name was adopted in 1960. Our executive offices are located at 225
Franklin Street, Boston, Massachusetts 02110 (telephone (617) 786-3000).

                                   THE TRUSTS

    Each of the trusts is a statutory business trust formed under Delaware law
pursuant to a trust agreement, signed by State Street, as depositor of each
trust, and the property trustee, the Delaware trustee and the administrative
trustees (each as defined below), and the filing of a certificate of trust with
the Delaware Secretary of State. The trust agreement of each trust will be
amended and restated in its entirety, each as so amended and restated, a "TRUST
AGREEMENT," prior to the issuance of capital securities by the trust,
substantially in the form filed as an exhibit to the registration statement of
which this prospectus forms a part. Each trust agreement will be qualified as an
indenture under the Trust Indenture act of 1939, as amended, the "TRUST
INDENTURE ACT."

    Each trust exists for the exclusive purposes of:

o   issuing the capital securities and common securities representing undivided
    beneficial interests in the assets of the trust;

o   investing the gross proceeds of the capital securities and the common
    securities, together the "TRUST SECURITIES," in junior subordinated
    debentures; and

o   engaging in only those activities necessary or incidental thereto.

    All of the common securities will be directly or indirectly owned by us. The
common securities of each trust will rank equally, and payments will be made pro
rata with the capital securities of that trust, except that upon an event of
default under the trust agreement, the rights of the holders of the common
securities to payment in respect of distributions and payments upon liquidation,
redemption and otherwise will be subordinated to the rights of the holders of
the capital securities. We will acquire common securities of each trust in an
aggregate liquidation amount equal to at least three percent of the total
capital of each trust.

    Each trust's business and affairs will be conducted by its trustees, each
appointed by State Street as holder of the common securities. The trustees of
each trust will be Bank One Trust Company, N.A. (as successor in interest to The
First National Bank of Chicago), as the property trustee, the "PROPERTY
TRUSTEE," Bank One Delaware, Inc., as the Delaware trustee, the "DELAWARE
TRUSTEE," and two individual trustees, the "ADMINISTRATIVE TRUSTEES," who are
employees or officers of or affiliated with State Street. Bank One Trust
Company, N.A., as property trustee, will act as sole trustee under each trust
agreement for purposes of compliance with the Trust Indenture Act. Bank One
Trust Company, N.A. will also act as trustee under the guarantees and the junior
subordinated indenture. See "Description of Guarantees" and "Description of
Junior Subordinated Debentures."

    The holder of the common securities of each trust, or the holders of a
majority in liquidation amount of the trust's capital securities if an event of
default under the trust agreement has occurred and is continuing, will be
entitled to appoint, remove or replace the property trustee and/or the Delaware
trustee for such trust. The right to vote to appoint, remove or replace the
administrative trustees is vested exclusively in the holders of the common
securities, and in no event will the holders of capital securities have such
right.


                                       -9-


    Unless otherwise specified in the applicable prospectus supplement, each
trust has a term of approximately 55 years, but may terminated earlier as
provided in the applicable trust agreement.

    State Street will pay all fees and expenses related to the trusts and the
offering of trust securities.

    The principal executive office of each trust is c/o State Street Bank and
Trust Company, N.A., 61 Broadway, 15th Floor, New York, New York 10006,
telephone number (212) 612-3000.

                CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES

    Our consolidated ratios of earnings to fixed charges were as follows for the
five most recent fiscal years:

                                                  Year Ended December 31,

                             REASON FOR TRANSACTION

    On October 21, 1996, the Federal Reserve Board issued a press release
announcing that it had approved the use of certain cumulative preferred stock
instruments, such as the capital securities, as "Tier 1 capital" for purposes of
the Federal Reserve Board's capital guidelines for bank holding companies.
Because State Street intends to treat the capital securities as Tier 1 capital
and, under current United States federal tax law, will receive a tax deduction
for interest in respect of the junior subordinated debentures, the issuance of
the capital securities is a cost-effective method of raising capital on an
after-tax basis.

                                 USE OF PROCEEDS

    Each trust will use the proceeds of the sale of its capital securities to
acquire junior subordinated debentures from State Street. State Street intends
to use the net proceeds from the sale of the securities for general corporate
purposes unless otherwise indicated in the prospectus supplement or term sheet
relating to a specific issue of securities. State Street's general corporate
purposes may include extending credit to, or funding investments in, our
subsidiaries. The precise amounts and the timing of State Street's use of the
net proceeds will depend upon our subsidiaries' funding requirements and the
availability of other funds. Until State Street uses the net proceeds from the
sale of any of our securities for general corporate purposes, State Street will
use the net proceeds to reduce short-term indebtedness or for temporary
investments. State Street expects that it will, on a recurrent basis, engage in
additional financings as the need arises to finance its growth, through
acquisitions or otherwise, or to fund its subsidiaries. State Street and State
Street Bank regularly investigate possible acquisitions.

                DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES

    We may issue junior subordinated debentures from time to time in one or more
series under a junior subordinated indenture, dated as of December 15, 1996, as
supplemented from time to time, the "JUNIOR SUBORDINATED INDENTURE," between us
and Bank One Trust Company, N.A. (as successor in interest to The First National
Bank of Chicago), as trustee, the "DEBENTURE TRUSTEE." The junior subordinated
indenture is qualified under the Trust Indenture Act, and terms of the junior
subordinated debentures will include those stated in the junior subordinated
indenture and those made part of the junior subordinated indenture by reference
to the Trust Indenture Act.


                                      -10-


    Set forth below is a description of the general terms of the junior
subordinated debentures in which the trusts will invest the proceeds from the
issuance and sale of the trust securities. The particular terms of the junior
subordinated debentures will be described in the prospectus supplement relating
to the particular capital securities being offered. The following description is
not intended to be complete and is qualified by the indenture, the form of which
is filed as an exhibit to the registration statement which contains this
prospectus, and the Trust Indenture Act.

General

    We will issue the junior subordinated debentures as unsecured debt. The
junior subordinated debentures will be fully subordinated as set forth in the
junior subordinated indenture. See "Subordination" below. Each series of junior
subordinated debentures will rank equally with all other series of junior
subordinated indentures. The junior subordinated indenture does not limit the
aggregate principal amount of junior subordinated debentures which may be issued
and provides that the junior subordinated debentures may be issued from time to
time in one or more series. Because we are a holding company, our rights and the
rights of our creditors, including the holders of the junior subordinated
debentures, to participate in the assets of any of our subsidiaries upon the
subsidiary's liquidation or reorganization will be subject to the prior claims
of the subsidiary's creditors except to the extent that we may ourselves be a
creditor with recognized claims against the subsidiary. Except as otherwise
provided in the applicable prospectus supplement, the junior subordinated
indenture does not limit the incurrence or issuance by us of other secured or
unsecured debt.

    The prospectus supplement relating to the particular junior subordinated
debentures being offered will describe the terms of those securities, which may
include:

o   the title of the junior subordinated debentures;

o   any limit upon the aggregate principal amount of junior subordinated
    debentures;

o   the date or dates on which the principal of the junior subordinated
    debentures is payable or the method of determination thereof;

o   any fixed or variable interest rate or rates per annum;

o   the place where the principal of and premium, if any, and interest on the
    junior subordinated debentures will be payable and where the junior
    subordinated debentures may be presented for registration of transfer or
    exchange;

o   any provisions for redemption, the redemption price and any remarketing
    arrangements;

o   the minimum denominations;

o   whether the debt securities are denominated or payable in United States
    dollars or a foreign currency or units of two or more foreign currencies;

o   if other than the principal amount, the portion of the principal amount of
    the debt securities payable upon acceleration of the maturity of the debt
    securities;

o   any index used to determine the amount of payment of principal of, and any
    premium and interest on, the debt securities;

o   any additional or different events of default that apply to any debt
    securities of the series and any change in the right of the trustee or the
    required holders of those debt securities to declare the principal thereof
    due and payable;


                                      -11-


o   any additional or different covenants that apply to any debt securities of
    the series;

o   any additions or changes to the junior subordinated indenture with respect
    to such junior subordinated debentures necessary to permit the issuance of
    the junior subordinated debentures in bearer form, registrable or not
    registrable as to principal, and with or without interest coupons;

o   the terms and conditions relating to the issuance of a temporary global
    security representing all of the junior subordinated debentures and the
    exchange of such temporary global security for definitive junior
    subordinated debentures;

o   whether the junior subordinated debentures will be issued in whole or in
    part in the form of one or more global securities and the depositary for any
    such global securities;

o   the appointment of any paying agent or agents;

o   the terms and conditions of any obligation or right of State Street or a
    holder to convert or exchange the junior subordinated debentures into
    capital securities; and

o   any other terms of the debt securities that are not inconsistent with the
    provisions of the applicable indenture.

    Junior subordinated debentures may be sold at a substantial discount below
their stated principal amount, bearing no interest or interest at a rate which
at the time of issuance is below market rates. Certain United States federal
income tax consequences and special considerations applicable to any such junior
subordinated debentures will be described in the applicable prospectus
supplement.

    If a prospectus supplement specifies that the junior subordinated debentures
will be denominated in a currency or currency unit other than United States
dollars, the prospectus supplement shall also specify the denomination in which
the junior subordinated debentures will be issued and the coin or currency in
which the principal, premium, if any, and interest, if any, on the junior
subordinated debentures will be payable, which may be United States dollars
based upon the exchange rate for such other currency or currency unit existing
on or about the time a payment is due.

    If any index is used to determine the amount of payments of principal of,
premium, if any, or interest on any series of junior subordinated debentures,
special United States federal income tax, accounting and other considerations
will be described in the applicable prospectus supplement.

Additional Interest

    If, at any time a trust is required to pay any taxes, duties, assessments or
governmental charges of whatever nature, other than withholding taxes, imposed
by the United States, or any other taxing authority, then we will be required to
pay additional interest on the junior subordinated debentures. The amount of any
additional interest will be an amount sufficient so that the net amounts
received and retained by the trust after paying any such taxes, duties,
assessments or other governmental charges will be not less than the amounts that
the trust would have received had no such taxes, duties, assessments or other
governmental charges been imposed. This means that the trust will be in the same
position it would have been in if it did not have to pay such taxes, duties,
assessments or other charges.

Denominations, Registration and Transfer

    Unless otherwise indicated in the applicable prospectus supplement, we will
issue the junior subordinated debentures in registered form only, without
coupons. Junior subordinated debentures of any series will be exchangeable for
other junior subordinated debentures of the same issue and series, of any
authorized denominations, of a like principal amount, of the same original issue
date and stated maturity and bearing the same interest rate.


                                      -12-


    Junior subordinated debentures may be presented for exchange as provided
above, and may be presented for registration of transfer at the office of the
appropriate securities registrar or at the office of any transfer agent
designated by us for such purposes. No service charge will be made for any
transfer or exchange of the junior subordinated debentures. However, we or the
debenture trustee may require a holder to pay an amount sufficient to cover any
tax or other governmental charge payable in connection with a transfer or
exchange. We will appoint the debenture trustee as securities registrar under
the junior subordinated indenture. If the applicable prospectus supplement
refers to any transfer agents, in addition to the securities registrar,
initially designated by us with respect to any series of junior subordinated
debentures, we may at any time rescind the designation of any such transfer
agent or approve a change in the location through which any such transfer agent
acts, provided that we maintain a transfer agent in each place of payment of
such series. We may at any time designate additional transfer agents with
respect to any series of junior subordinated debentures.

    In the event of any redemption, neither we nor the debenture trustee will be
required to:

o   issue, register the transfer of, or exchange, junior subordinated debentures
    of any series during a period beginning at the opening of business 15 days
    before the day of selection for redemption and ending at the close of
    business on the day of mailing of notice of redemption; or

o   transfer or exchange any junior subordinated debentures so selected for
    redemption, except, in the case of any junior subordinated debentures being
    redeemed in part, any portion thereof not to be redeemed.

Payment and Paying Agents

    Unless otherwise indicated in the applicable prospectus supplement, we will
pay principal and any premium and interest on junior subordinated debentures
(other than those in global form) at the office of the debenture trustee in the
city of New York or at the office of any paying agent that we may designate from
time to time. However, at our option, it may pay any interest by check mailed to
the holders of registered junior subordinated debentures at their registered
addresses or by transfer to an account maintained by a holder of registered
junior subordinated debentures, as specified in the securities register. Unless
otherwise indicated in the applicable prospectus supplement, payment of any
interest on junior subordinated debentures will be made to the person in whose
name the junior subordinated debentures are registered on the applicable record
date, except in the case of defaulted interest. We may at any time designate
additional paying agents or rescind the designation of any paying agent,
provided that we at all times maintain a paying agent in each place of payment
for each series of junior subordinated debentures.

    Any amounts deposited with the debenture trustee or any paying agent, or
then held by us in trust, for the payment of the principal of any premium, if
any, or interest on any junior subordinated debentures and remaining unclaimed
for two years after such amounts have become due and payable shall, at our
request, be repaid to us, and the holder of the junior subordinated debenture
will be able to look only to us for payment, as a general unsecured creditor.

Option to Defer Interest Payments

    If provided in the applicable prospectus supplement, we will have the right
from time to time during the term of any series of junior subordinated
debentures to defer payment of interest for up to such number of consecutive
interest payment periods as may be specified in the applicable prospectus
supplement, subject to the terms, conditions and covenants, if any, specified in
such prospectus supplement. Such deferral, however, may not extend beyond the
stated maturity of such series of junior subordinated debentures. Certain United
States federal income tax consequences and special considerations applicable to
any such junior subordinated debentures will be described in the applicable
prospectus supplement.


                                      -13-


Redemption

    Unless otherwise indicated in the applicable prospectus supplement, the
junior subordinated debentures will not be subject to any sinking fund.

    Unless otherwise indicated in the applicable prospectus supplement, we may,
at our option and subject to receipt of prior approval by the Federal Reserve
(if required), redeem the junior subordinated debentures of any series in whole
at any time or in part from time to time. If the junior subordinated debentures
of any series are so redeemable only on or after a specified date or upon the
satisfaction of additional conditions, the applicable prospectus supplement will
specify such date or describe such conditions. Except as otherwise specified in
the applicable prospectus supplement, the redemption price for any junior
subordinated debenture so redeemed will equal any accrued and unpaid interest
thereon to the redemption date, plus 100% of the principal amount thereof.

    Except as otherwise specified in the applicable prospectus supplement, if a
tax event (as defined below) in respect of a series of junior subordinated
debentures or an investment company event or capital treatment event (each as
defined below) shall occur and be continuing, we may, at our option and subject
to receipt of prior approval by the Federal Reserve (if required), redeem such
series of junior subordinated debentures in whole, but not in part, at any time
within 90 days following of the occurrence of such tax event, investment company
event or capital treatment event, at a redemption price equal to 100% of the
principal amount of such junior subordinated debentures then outstanding plus
accrued and unpaid interest to the date fixed for redemption, except as
otherwise specified in the applicable prospectus supplement.

    "TAX EVENT" means the receipt by the trust of an opinion of counsel
experienced in such matters to the effect that, as a result of any amendment to,
or change (including any announced proposed change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein, or as a result of any official
administrative pronouncement or judicial decision interpreting or applying such
laws or regulations, which amendment or change is effective or which proposed
change, pronouncement or decision is announced on or after the date of issuance
of such capital securities, there is more than an insubstantial risk that (i)
the trust is, or will be within 90 days of the date of such opinion, subject to
United States federal income tax with respect to income received or accrued on
the corresponding series of corresponding junior subordinated debentures, (ii)
interest payable by State Street on such series of corresponding junior
subordinated debentures is not, or within 90 days of the date of such opinion,
will not be, deductible by State Street, in whole or in part, for United States
federal income tax purposes, or (iii) such trust is, or will be within 90 days
of the date of such opinion, subject to more than a de minimis amount of other
taxes, duties or other governmental charges.

    "INVESTMENT COMPANY EVENT" means the receipt by the trust of an opinion of
counsel experienced in such matters to the effect that, as a result of the
occurrence of a change in law or regulation or a written change (including any
announced prospective change) in interpretation or application of law or
regulation by any legislative body, court, governmental agency or regulatory
authority, there is more than an insubstantial risk that the trust is or will be
considered an "investment company" that is required to be registered under the
Investment Company Act of 1940, which change or prospective change becomes
effective or would become effective, as the case may be, on or after the date of
the issuance of the capital securities.

    "CAPITAL TREATMENT EVENT" means our reasonable determination that, as a
result of any amendment to, or change (including any proposed change) in, the
laws (or any regulations thereunder) of the United States or any political
subdivision thereof or therein, or as a result of any official or administrative
pronouncement or action or judicial decision interpreting or applying such laws
or regulations, which amendment or change is effective or which proposed change,
pronouncement, action or decision is announced on or after the date of issuance
of the applicable capital securities under the applicable trust agreement, there
is more than an insubstantial risk that we will not be entitled to treat an
amount equal to the liquidation amount of the applicable capital securities as
"Tier I Capital" (or the then equivalent thereof) for purposes of the capital
adequacy guidelines of the Federal Reserve, as then in effect and applicable to
us.


                                      -14-


    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of junior subordinated
debentures to be redeemed at its registered address. Unless we default in
payment of the redemption price, on and after the redemption date, interest will
cease to accrue on such junior subordinated debentures or portions thereof
called for redemption.

Restrictions on Certain Payments

    If junior subordinated debentures are issued to a trust or a trustee of a
trust in connection with the issuance of trust securities by a trust and:

o   there shall have occurred and be continuing an event of default with respect
    to the junior subordinated debentures of which we have actual knowledge and
    which we have not taken reasonable steps to cure;

o   we shall be in default relating to our payment of any obligations under the
    guarantee; or

o   we shall have given notice of our election to defer payments of interest on
    the junior subordinated debentures by extending the interest payment period
    and such period, or any extension of such period, shall be continuing;

then:

o   we shall not declare or pay any dividend on, make any distributions relating
    to, or redeem, purchase, acquire or make a liquidation payment relating to,
    any of its capital stock or make any guarantee payment with respect thereto
    other than:

    (1)  repurchases, redemptions or other acquisitions of shares of our capital
         stock in connection with any employee benefit plans or any other
         contractual obligation, other than a contractual obligation ranking
         equally with or junior to the junior subordinated debentures;

    (2)  as a result of an exchange or conversion of any class or series of our
         capital stock for any other class or series of our capital stock;

    (3)  the purchase of fractional interests in shares of our capital stock
         pursuant to the conversion or exchange provisions of such capital stock
         or the security being converted or exchanged;

    (4)  any declaration of a dividend in connection with any rights plan, or
         the issuance of rights, stock or other property under any rights plan,
         or the redemption or repurchase of rights pursuant thereto; or

    (5)  any dividend in the form of stock, warrants, options or other rights
         where the dividend stock or stock issuable upon exercise of such
         warrants, options or other rights is the same stock as that on which
         the dividend is being paid or ranks equally with or junior to such
         stock; and

o   we shall not make any payment of interest, principal or premium, if any, on
    or repay, repurchase or redeem any debt securities issued by us that rank
    equally with or junior to the junior subordinated debentures.

Limitation on Mergers and Sales of Assets

    The junior subordinated indenture provides that we may not consolidate with,
or merge into, any other corporation or convey or transfer its properties and
assets substantially as an entirety unless:

o   the successor entity is a corporation, partnership or trust organized in the
    United States and expressly assumes our obligations under the junior
    subordinated indenture;


                                      -15-


o   after giving effect thereto, no event of default and no event which, after
    notice or lapse of time, or both, would become an event of default, shall
    have occurred and be continuing under the junior subordinated indenture;

o   such transaction is permitted under the related trust agreement and
    guarantee; and

o   certain other conditions as prescribed by the junior subordinated indenture
    are met.

    The covenants contained in the indenture would not necessarily protect
holders of the junior subordinated debentures in the event of a decline in
credit quality resulting from takeovers, recapitalizations or similar
restructurings.

Events of Default, Waiver and Notice

    The junior subordinated indenture provides that the following are events of
default relating to the junior subordinated debentures:

o   default in the payment of the principal of, or premium, if any, on, any
    junior subordinated debentures at maturity;

o   default for 30 days in the payment of any installment of interest on any
    junior subordinated debentures;

o   default for 90 days after written notice in the performance of any other
    covenant in respect of the junior subordinated debentures; and

o   specified events of bankruptcy, insolvency or reorganization of State
    Street.

    If an event of default under the junior subordinated indenture shall occur
and be continuing, either the debenture trustee or the holders of not less than
25 percent in aggregate principal amount of the junior subordinated debentures
of that series then outstanding may declare the principal of all junior
subordinated debentures of that series to be due and payable immediately. If the
holders of junior subordinated debentures fail to make such declaration, the
holders of at least 25 percent in aggregate liquidation amount of the related
capital securities shall have such right.

    The holders of a majority in aggregate outstanding principal amount of that
series of junior subordinated debentures may annul the declaration and waive the
default. If the holders of junior subordinated debentures fail to annul such
declaration and waive such default, the holders of at least 25 percent in
aggregate liquidation amount of the related capital securities shall have such
right.

    The holders of a majority in aggregate outstanding principal amount of that
series of junior subordinated debentures may waive any default, except a default
in payment of principal or interest, unless such default has been cured and a
sum sufficient to pay all matured installments of interest and principal due
other than by acceleration has been deposited with the debenture trustee, or a
default in respect of a covenant or provision that under the junior subordinated
indenture cannot be modified or amended without the consent of the holder of
each outstanding junior subordinated debenture. If the holders of junior
subordinated debentures fail to waive such default, the holders of a majority in
aggregate liquidation amount of the related capital securities shall have such
right.

    The holders of a majority in principal amount of the junior subordinated
debentures of any series affected shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
debenture trustee under the junior subordinated indenture.

    We are required to furnish to the debenture trustee annually a statement as
to the performance of our obligations under the junior subordinated indenture
and as to any default in such performance.


                                      -16-


    If a debenture event of default shall have occurred and be continuing, the
property trustee will have the right to declare the principal of and the
interest on the corresponding junior subordinated debentures, and any other
amounts payable under the junior subordinated indenture, to be due and payable
and to enforce its other rights as a creditor with respect to the corresponding
junior subordinated debentures.

Distribution of the Junior Subordinated Debentures

    Under circumstances discussed more fully in the prospectus supplement
involving the dissolution of a trust, provided that any required regulatory
approval is obtained, junior subordinated debentures will be distributed to the
holders of the trust securities in liquidation of that trust. See "Description
of the Capital Securities--Liquidation Distribution upon Dissolution."

    If the junior subordinated debentures are distributed to the holders of the
capital securities, we will use our best efforts to have the junior subordinated
debentures listed on the New York Stock Exchange or on such other national
securities exchange or similar organization on which the capital securities are
then listed or quoted.

Modification of Junior Subordinated Indenture

    From time to time we and the debenture trustee may, without the consent of
the holders of the junior subordinated debentures, waive or supplement the
junior subordinated indenture for specified purposes, including, among other
things:

o   evidencing the succession of another person to State Street;

o   conveying, transferring, assigning, mortgaging or pledging any property to
    or with the debenture trustee or surrendering any right or power conferred
    upon us in the junior subordinated indenture;

o   adding to the covenants of State Street for the benefit of other holders of
    all or any series of securities;

o   adding any additional events of default for the benefit of other holders of
    all or any series of securities;

o   changing or eliminating any of the provisions of the junior subordinated
    indenture, provided that any such change or elimination shall not apply to
    any outstanding securities, or shall become effective only when there is no
    security outstanding of any series created prior to the execution of the
    supplemental indenture that is entitled to the benefit of such provision;

o   curing ambiguities, defects or inconsistencies without materially and
    adversely affecting the holders of the junior subordinated debentures or the
    related capital securities;

o   evidencing and providing for the acceptance of appointment under the junior
    subordinated indenture by a successor trustee with respect to the securities
    of one or more series and adding to or changing any of the provisions of the
    indenture as shall be necessary to provide for or facilitate the
    administration of the trusts under the indenture by more than one trustee;
    and

o   qualifying the junior subordinated indenture under the Trust Indenture Act.

We and the debenture trustee may make modifications and amendments to the
indenture with the consent of the holders of a majority in principal amount of
the junior subordinated debentures at the time outstanding. However, no


                                      -17-


such modification or amendment may, without the consent of the holder of each
junior subordinated debenture affected thereby:

o   modify the payment terms of the junior subordinated debentures; or

o   reduce the percentage of holders of junior subordinated debentures necessary
    to modify or amend the indenture or waive compliance by us with any covenant
    or past default.

    If the junior subordinated debentures are held by a trust or a trustee of a
trust, no modification may be made that adversely affects the holders of the
related capital securities, and no termination of the junior subordinated
indenture may occur, and no waiver of any event of default or compliance with
any covenant will be effective without the prior consent of a majority in
liquidation preference of trust securities of that trust. If the consent of the
holder of each outstanding junior subordinated debenture is required, no
modification shall be effective without the prior consent of each holder of
related capital securities.

    In addition, we and the debenture trustee may execute, without the consent
of any holder of junior subordinated debentures, any supplemental junior
subordinated indenture for the purpose of creating any new series of junior
subordinated indentures.

Enforcement of Certain Rights by Holders of Capital Securities

    If a debenture event of default with respect to a series of corresponding
junior subordinated debentures has occurred and is continuing and such event of
default is the result of our failure to pay interest or principal on the
corresponding junior subordinated debentures when due, a holder of related
capital securities may institute a legal proceeding directly against us for
enforcement of payment to such holder of the principal of or interest on such
corresponding junior subordinated debentures having a principal amount equal to
the aggregate liquidation amount of the related capital securities. We may not
amend the junior subordinated indenture to remove this right without the prior
written consent of the holders of all of the capital securities outstanding. If
such right is removed, the applicable trust may become subject to reporting
obligations under the Exchange Act. We will have the right under the junior
subordinated indenture to set off any payment made by us to such holder of
capital securities in connection with any such direct action.

    The holders of the capital securities will not be able to exercise directly
any remedies other than those set forth in the preceding paragraph unless there
shall have been an event of default under the applicable trust agreement. Please
see "Description of Capital Securities--Events of Default; Notice."

Defeasance and Discharge

    The junior subordinated indenture provides that when:

    (1)  all junior subordinated debentures not previously delivered to the
         debenture trustee for cancellation have become due and payable or will
         become due and payable at their stated maturity within one year,

    (2)  we deposit with the debenture trustee, in trust, funds sufficient to
         pay all the principal of, and interest and premium, if any, on the
         junior subordinated debentures when such payments are due,

    (3)  we have paid all other sums payable under the indenture by us, and

    (4)  we have delivered to the debenture trustee an officers' certificate and
         an opinion of counsel each stating that all conditions precedent in the
         indenture relating to the satisfaction and discharge of the indenture
         have been complied with


                                      -18-


then the junior subordinated indenture will cease to be of further effect
(except as to our obligations to pay all other sums due under the junior
subordinated indenture and to provide the officers' certificates and opinions of
counsel described therein), and we will be deemed to have satisfied and
discharged the junior subordinated indenture.

Conversion or Exchange

    The junior subordinated debentures may be convertible or exchangeable into
junior subordinated debentures of another series or into capital securities of
another series, on the terms provided in the applicable prospectus supplement.
Such terms may include provisions for conversion or exchange, either mandatory,
at the option of the holder, or at our option, in which case the number of
shares of capital securities or other securities to be received by the holders
of junior subordinated debentures would be calculated as of a time and in the
manner stated in the applicable prospectus supplement.

Subordination

    The junior subordinated indenture contains a covenant by us that any junior
subordinated debentures issued thereunder will be subordinate and junior in
right of payment to all senior debt (as defined below) to the extent provided
therein. If we make any payment or distribution of our assets upon any
liquidation, dissolution, winding up, reorganization, assignment for the benefit
of creditors, marshaling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding, the holders of senior debt will first be entitled to
receive payment in full of principal of and premium and interest, if any, on
such senior debt before the holders of junior subordinated debentures will be
entitled to receive or retain any payment in respect of the principal of and
premium and interest, if any, on the junior subordinated debentures. However,
holders of senior debt will not be entitled to receive payment of any such
amounts if the subordination provisions of such senior debt would require
holders to pay such amounts over to the obligees on trade accounts payable or
other liabilities arising in the ordinary course of our business.

    In the event of the acceleration of the maturity of any junior subordinated
debentures, the holders of all senior debt outstanding at the time of such
acceleration will first be entitled to receive payment in full of all amounts
due thereon, including any amounts due upon acceleration, before the holders of
the junior subordinated debentures will be entitled to receive or retain any
payment in respect of the principal of or premium or interest, if any, on the
junior subordinated debentures. However, the holders of senior debt will not be
entitled to receive payment of any such amounts if the subordination provisions
of such senior debt would require holders to pay such amounts over to the
obligees on trade accounts payable or other liabilities arising in the ordinary
course of State Street's business.

    No payments on accounts of principal or premium, if any, or interest in
respect of the junior subordinated debentures may be made if there shall have
occurred and be continuing a default in any payment with respect to senior debt
or an event of default with respect to any senior debt resulting in the
acceleration of the maturity thereof, or if any judicial proceeding are pending
with respect to any such default.

    "DEBT" means, with respect to any person, whether recourse is to all or a
portion of the assets of such person and whether or not contingent:

o   every obligation of such person for money borrowed;

o   every obligation of such person evidenced by bonds, debentures, notes or
    other similar instruments, including obligations incurred in connection with
    the acquisition of property, assets or businesses;

o   every reimbursement obligation of such person with respect to letters of
    credit, bankers' acceptances or similar facilities issued for the account of
    such person;


                                      -19-


o   every obligation of such person issued or assumed as the deferred purchase
    price of property or services other than trade accounts payable or accrued
    liabilities arising in the ordinary course of business;

o   every capital lease obligation of such person;

o   every obligation of such person for claims in respect of derivative products
    such as interest and foreign exchange rate contracts, commodity contracts
    and similar arrangements; and

o   every obligation of the type referred to above of another person and all
    dividends of another person the payment of which, in either case, such
    person has guaranteed or is responsible or liable for, directly or
    indirectly, as obligor or otherwise.

    "SENIOR DEBT" means the principal of and premium and interest, if any,
including interest accruing on or after the filing of any petition in bankruptcy
or for reorganization relating to us whether or not such claim for post-petition
interest is allowed in such proceeding, on debt, whether incurred on or prior to
the date of the junior subordinated indenture or thereafter incurred, unless, in
the instrument creating or evidencing the same or pursuant to which the same is
outstanding, it is provided that such obligations are not superior in right of
payment to the junior subordinated debentures or to other debt that is equal or
subordinated to the junior subordinated debentures, other than:

o   any debt of State Street which when incurred and without respect to any
    election under Section 1111(b) of the United States Bankruptcy Code of 1978,
    as amended, was without recourse to State Street;

o   any debt of State Street to any of its subsidiaries;

o   any debt to any of our employees;

o   any debt which by its terms is subordinated to trade accounts payable or
    accrued liabilities arising in the ordinary course of business to the extent
    that payments made to the holders of such debt by the holders of the junior
    subordinated debentures as a result of the subordination provisions of the
    junior subordinated indenture would be greater than such payments otherwise
    would have been as a result of any obligation of such holders of such debt
    to pay amounts over to the obligees on such trade accounts payable or
    accrued liabilities arising in the ordinary course of business as a result
    of subordination provisions to which such debt is subject; and

o   any other debt securities issued pursuant to the junior subordinated
    indenture.

    The junior subordinated indenture places no limitation on the amount of
senior debt that we may incur. We expect from time to time to incur additional
indebtedness and other obligations constituting senior debt.

    The junior subordinated indenture provides that any of the subordination
provisions described above that relate to any particular issue of junior
subordinated debentures may be changed prior to such issuance. Any such change
would be described in the applicable prospectus supplement.

Governing Law

    The junior subordinated indenture and the junior subordinated debentures
will be governed by, and construed in accordance with, the internal laws of the
State of New York.

The Debenture Trustee

    The debenture trustee will have all of the duties and responsibilities
specified under the Trust Indenture Act. Subject to those provisions, the
debenture trustee is under no obligation to exercise any of the powers vested in
it by the junior subordinated indenture at the request of any holder of junior
subordinated debentures unless offered


                                      -20-


reasonable indemnity by such holder against the costs, expenses and liabilities
that might be incurred thereby. The debenture trustee is not required to expend
or risk its own funds or otherwise incur personal financial liability in the
performance of its duties if the debenture trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured it.

Corresponding Junior Subordinated Debentures

    State Street may issue one or more series of junior subordinated debentures
under the junior subordinated indenture with terms corresponding to the terms of
a series of related capital securities, the "CORRESPONDING JUNIOR SUBORDINATED
DEBENTURES." In each such instance, concurrently with the issuance of each
trust's capital securities, the trust will invest the proceeds thereof and the
consideration paid by us for the common securities in the series of
corresponding junior subordinated debentures issued by us to such trust. Each
series of corresponding junior subordinated debentures will be in the principal
amount equal to the aggregate stated liquidation amount of the related capital
securities and the common securities of the trust and will rank equally with all
other series of junior subordinated debentures. Holders of the related capital
securities for a series of corresponding junior subordinated debentures will
have the rights, in connection with modifications to the junior subordinated
indenture or upon occurrence of debenture events of default as described under
"--Modification of Junior Subordinated Indenture," "-- Debenture Events of
Default" and "Enforcement of Certain Rights by Holders of Capital Securities."

    Unless otherwise specified in the applicable prospectus supplement, if a tax
event relating to a trust shall occur and be continuing, we may, at our option
and subject to prior approval of the Federal Reserve (if required), redeem the
corresponding junior subordinated debentures at any time within 90 days of the
occurrence of such tax event, in whole but not in part, subject to the
provisions of the junior subordinated indenture and whether or not such
corresponding junior subordinated debentures are then redeemable at our option.
The redemption price for any corresponding junior subordinated debentures shall
be equal to 100% of the principal amount of such corresponding junior
subordinated debentures then outstanding plus accrued and unpaid interest to the
date fixed for redemption. For so long as the applicable trust is the holder of
all the outstanding corresponding junior subordinated debentures of such series,
the proceeds of any such redemption will be used by the trust to redeem the
corresponding trust securities in accordance with their terms. We may not redeem
a series of corresponding junior subordinated debentures in part unless all
accrued and unpaid interest has been paid in full on all outstanding
corresponding junior subordinated debentures of such series for all interest
proceeds terminating on or prior to the date of redemption.

    We will covenant, as to each series of corresponding junior subordinated
debentures:

o   to directly or indirectly maintain 100% ownership of the common securities
    of the trust unless a permitted successor succeeds to ownership of the
    common securities

o   not to voluntarily terminate, wind up or liquidate any trust, except, if so
    specified in the applicable prospectus supplement and upon prior approval of
    the Federal Reserve (if required):

        o in connection with a distribution of corresponding junior subordinated
    debentures to the holders of the capital securities in exchange therefor
    upon liquidation of the trust, or

        o in connection with certain mergers, consolidations or amalgamations
    permitted by the related trust agreement, in either such case, if so
    specified in the Applicable Prospectus Supplement upon prior approval of the
    Federal Reserve if then so required under applicable capital guidelines or
    policies; and

o   to use its reasonable efforts, consistent with the terms and provisions of
    the related trust agreement, to cause such trust to remain classified as a
    grantor trust and not as an association taxable as a corporation for United
    States federal income tax purposes.


                                      -21-


                      DESCRIPTION OF THE CAPITAL SECURITIES

     The capital securities will be issued pursuant to the terms of an amended
and restated trust agreement. The trust agreement will be qualified as an
indenture under the Trust Indenture Act. The property trustee, Bank One Trust
Company, N.A., will act as trustee for the capital securities under the trust
agreement for purposes of compliance with the provisions of the Trust Indenture
Act. The terms of the capital securities will include those stated in the trust
agreement and those made part of the trust agreement by the Trust Indenture Act.

    Set forth below is a summary of the material terms and provisions of the
capital securities. This summary, which describes the material provisions of the
capital securities, is not intended to be complete and is qualified by the trust
agreement, the form of which is filed as an exhibit to the registration
statement which contains this prospectus supplement, the Delaware Business Trust
Act and the Trust Indenture Act.

General

     The declaration authorizes the trustees to issue the trust securities on
behalf of the trust. The trust securities represent undivided beneficial
interests in the assets of the trust. We will own, directly or indirectly, all
of the common securities. The common securities rank equally, and payments will
be made on a pro rata basis, with the capital securities. However, if an event
of default under a trusts's trust agreement occurs and is continuing, the rights
of the holders of the common securities to receive payments will be subordinated
to the rights of the holders of the capital securities.

    The trust agreement does not permit the trust to issue any securities other
than the trust securities or to incur any indebtedness. Under the trust
agreement, the property trustee will own the junior subordinated debentures
purchased by the trust for the benefit of the holders of the trust securities.
Each guarantee agreement executed by us for the benefit of the holders of a
trust's trust securities, each a "GUARANTEE," will be a guarantee on a
subordinated basis with respect to the related trust securities but will not
guarantee payment of distributions or amounts payable on redemption or
liquidation of such trust securities when the related trust does not have funds
on hand available to make such payments. Please see "Descriptions of
Guarantees."

Distributions

    Distributions on the capital securities:

o   will be cumulative;

o   will accumulate from the date of original issuance; and

o   will be payable on such dates as specified in the applicable prospectus
    supplement.

    In the event that any date on which distributions are payable on the capital
securities is not a business day, then payment of the distribution will be made
on the next succeeding business day, and without any interest or other payment
in respect to any such delay, except that, if such business day is in the next
calendar year, payment of the distribution will be made on the immediately
preceding business day. Each date on which distributions are payable in
accordance with the foregoing is referred to as a "DISTRIBUTION DATE." The term
"DISTRIBUTION" includes any interest payable on unpaid distributions unless
otherwise stated.

    The amount of distributions payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. The amount of distributions
payable for any period shorter than a full quarterly period will be computed on
the basis of the actual number of days elapsed per 30-day month. Distributions
to which holders of


                                      -22-


capital securities are entitled will accumulate additional distributions at the
rate per annum if and as specified in the applicable prospectus supplement.

    If provided in the applicable prospectus supplement, we have the right under
the junior subordinated indenture, pursuant to which we will issue the
corresponding junior subordinated debentures, to defer the payment of interest
on any series of the corresponding junior subordinated debentures for up to a
number of consecutive interest payment periods that will be specified in the
prospectus supplement relating to such series, an "EXTENSION PERIOD," provided,
that no extension period may extend beyond the stated maturity of the
corresponding junior subordinated debentures.

    As a consequence of any such deferral, distributions on the related capital
securities would be deferred, but would continue to accumulate additional
distributions at the rate per annum set forth in the prospectus supplement for
such capital securities, by the trust during any extension period. If we
exercise our deferral right, then during any extension period, we may not:

o   make any payment of principal of or interest or premium, if any, on or
    repay, repurchase or redeem any debt securities that rank equally in all
    respects with or junior in interest to the junior subordinated debentures of
    such series; or

o   declare or pay any dividends or distributions on, or redeem, purchase,
    acquire or make a liquidation payment with respect to, any shares of our
    capital stock, other than:

        o repurchases, redemptions or other acquisitions of shares of our
    capital stock in connection with any employment contract, benefit plan or
    other similar arrangement with or for the benefit of any one or more
    employees, officers, directors or consultants, in connection with a dividend
    reinvestment or stockholder stock purchase plan or in connection with the
    issuance of our capital stock, or securities convertible into or exercisable
    for such capital stock, as consideration in an acquisition transaction
    entered into prior to the applicable extension period,

        o as a result of an exchange or conversion of any class or series of our
    capital stock or any capital stock of our subsidiaries, for any class or
    series of our capital stock, or of any class or series of our indebtedness
    for any class or series of our capital stock,

        o the purchase of fractional interests in shares of our capital stock
    pursuant to the conversion or exchange provisions of such capital stock or
    the securities being converted or exchanged,

        o any declaration of a dividend in connection with any rights plan, or
    the issuance of rights, stock or other property under any rights plan, or
    the redemption or repurchase of rights pursuant thereto, or

        o any dividend in the form of stock, warrants, options or other rights
    where the dividend stock or the stock issuable upon exercise of such
    warrants, options or other rights is the same stock as that on which the
    dividend is being paid or ranks equally with or junior to such stock.

    The revenue of each trust available for distribution to holders of its
capital securities will be limited to payments under the corresponding junior
subordinated debentures in which the trust will invest the proceeds from the
issuance and sale of its trust securities. Please see "Description of Junior
Subordinated Debentures--Corresponding Junior Subordinated Debentures." If we do
not make interest payments on such corresponding junior subordinated debentures,
the property trustee will not have funds available to pay distributions on the
related capital securities. The payment of distributions, if and to the extent
the trust has funds legally available for the payment of such distributions and
cash sufficient to make such payments, is guaranteed by us on the basis set
forth under "Description of Guarantees."


                                      -23-


    Distributions on the capital securities will be payable to the holders
thereof as they appear on the register of such trust on the relevant record
dates, which, as long as the capital securities remain in book-entry form, will
be one business day prior to the relevant date of distribution. Subject to any
applicable laws and regulations and the provisions of the applicable trust
agreement, each such payment will be made as described under "Book-Entry
Issuance." In the event any capital securities are not in book-entry form, the
relevant record date for such capital securities shall be the date at least 15
days prior to the relevant date of distribution, as specified in the applicable
prospectus supplement.

Redemption or Exchange

    Mandatory Redemption

    Upon the repayment or redemption, in whole or in part, of any corresponding
junior subordinated debentures, whether at maturity or upon earlier redemption
as provided in the junior subordinated indenture, the property trustee shall
apply the proceeds from such repayment or redemption to redeem a like amount (as
defined below) of the trust securities, upon not less than 30 nor more than 60
days' notice, at a redemption price, the "REDEMPTION PRICE," equal to the
aggregate liquidation amount of such trust securities plus accumulated but
unpaid distributions to the date of redemption, the "REDEMPTION DATE," and the
related amount of the premium, if any, paid by us upon the concurrent redemption
of such corresponding junior subordinated debentures. Please see "Description of
Junior Subordinated Debentures--Redemption." If less than all of any series of
corresponding junior subordinated debentures are to be repaid or redeemed on a
redemption date, then the proceeds from such repayment or redemption will be
allocated pro rata to the redemption of the related capital securities and the
common securities. The amount of premium, if any, paid by us upon the redemption
of all or any part of any series of any corresponding junior subordinated
debentures to be repaid or redeemed on a redemption date shall be allocated pro
rata to the redemption of the related capital securities and the common
securities.

    We will have the right to redeem any series of corresponding junior
subordinated debentures:

o   on or after such date as may be specified in the applicable prospectus
    supplement, in whole at any time or in part from time to time; or

o   at any time, in whole, but not in part, upon the occurrence of a tax event,
    investment company event or capital treatment event, in any case subject to
    receipt of prior approval by the Federal Reserve (if required). Please see
    "Description of Junior Subordinated Debentures--Redemption."

    Within 90 days of the occurrence of any tax event, investment company event
or capital treatment event in respect of a series of capital securities and
common securities shall occur and be continuing, we will have the right to
redeem the corresponding junior subordinated debentures in whole, but not in
part, and thereby cause a mandatory redemption of such capital securities and
common securities in whole, but not in part, at the redemption price. In the
event a tax event, investment company event or capital treatment event in
respect of a series of capital securities and common securities has occurred and
is continuing and we do not elect to redeem the corresponding junior
subordinated debentures and thereby cause a mandatory redemption of such capital
securities and common securities or to dissolve the related trust and cause the
corresponding junior subordinated debentures to be distributed to holders of
such capital securities and common securities in exchange therefor upon
liquidation of the trust as described below, such capital securities will remain
outstanding.

    "LIKE AMOUNT" means:

o   with respect to a redemption of any series of trust securities, trust
    securities of such series having a liquidation amount (as defined below)
    equal to that portion of the principal amount of corresponding junior
    subordinated debentures to be contemporaneously redeemed in accordance with
    the junior subordinated indenture, the proceeds of which will be used to pay
    the redemption price of such trust securities; and


                                      -24-


o   with respect to a distribution of corresponding junior subordinated
    debentures to holders of any series of trust securities in exchange therefor
    in connection with a dissolution or liquidation of the related trust,
    corresponding junior subordinated debentures having a principal amount equal
    to the liquidation amount of the trust securities of the holder to whom such
    corresponding junior subordinated debentures would be distributed.

    "LIQUIDATION AMOUNT" means the stated amount per trust security as set forth
in the applicable prospectus supplement.

    Distribution of Corresponding Junior Subordinated Debentures

    We will have the right at any time to liquidate any trust and cause the
junior subordinated debentures to be distributed to the holders of the trust
securities. This may require the prior approval of the Federal Reserve Board. If
the corresponding junior subordinated debentures are distributed to the holders
of the capital securities, we have the right at any time to dissolve any trust
and, after satisfaction of the liabilities of creditors of such trust as
provided by applicable law, cause such corresponding junior subordinated
debentures in respect of the related capital securities and common securities
issued by such trust to be distributed to the holders of such related capital
securities and common securities in exchange therefor upon liquidation of such
trust.

    After the liquidation date fixed for any distribution of corresponding
junior subordinated debentures for any series of capital securities:

o   such series of capital securities will no longer be deemed to be
    outstanding;

o   the depositary or its nominee, as the record holder of such series of
    capital securities, will receive a registered global certificate or
    certificates representing the corresponding junior subordinated debentures
    to be delivered upon such distribution; and

o   any certificates representing such series of capital securities not held by
    The Depository Trust Company ("DTC") or its nominee will be deemed to
    represent the corresponding junior subordinated debentures having a
    principal amount equal to the stated liquidation amount of such series of
    capital securities, and bearing accrued and unpaid interest in an amount
    equal to the accrued and unpaid distributions on such series of capital
    securities until such certificates are presented to the administrative
    trustees or their agent for transfer or reissuance.

    We cannot assure you as to the market prices for the capital securities or
the corresponding junior subordinated debentures that may be distributed in
exchange for capital securities if a dissolution and liquidation of a trust
were to occur. Accordingly, the capital securities that an investor may
purchase, or the corresponding junior subordinated debentures that the investor
may receive on dissolution and liquidation of a trust, may trade at a discount
to the price that the investor paid to purchase the capital securities.

Redemption Procedures

    Capital securities redeemed on each redemption date will be redeemed at the
redemption price with the applicable proceeds from the contemporaneous
redemption of the corresponding junior subordinated debentures. Redemptions of
the capital securities shall be made and the redemption price shall be payable
on each redemption date only to the extent that the related trust has funds on
hand available for the payment of such redemption price. See also "--
Subordination of Common Securities."

    If a trust gives a notice of redemption of its capital securities, then, by
12:00 noon, New York City time, on the redemption date, to the extent funds are
available, the property trustee will deposit irrevocably with DTC funds
sufficient to pay the applicable redemption price and will give DTC irrevocable
instructions and authority to pay the redemption price to the holders of such
capital securities. Please see "Book-Entry Issuance." If such capital


                                      -25-


securities are no longer in book-entry form, the property trustee, to the extent
funds are available, will irrevocably deposit with the paying agent for such
capital securities funds sufficient to pay the applicable redemption price and
will give such paying agent irrevocable instructions and authority to pay the
redemption price to the holders thereof upon surrender of their certificates
evidencing such capital securities.

    Notwithstanding the foregoing, distributions payable on or prior to the
redemption date for any capital securities called for redemption will be payable
to the holders of such capital securities on the relevant record dates for the
related distribution dates. If notice of redemption shall have been given and
funds deposited as required, then upon the date of such deposit:

o   all rights of the holders of such capital securities will cease, except the
    right of the holders of such capital securities to receive the redemption
    price, but without interest on such redemption price; and

o   such capital securities will cease to be outstanding.

    In the event that any date fixed for redemption of capital securities is not
a business day, then payment of the redemption price will be made on the next
succeeding business day, and without any interest or any other payment in
respect of any such delay, except that, if such business day falls in the next
calendar year, such payment will be made on the immediately preceding business
day. In the event that payment of the redemption price in respect of capital
securities called for redemption is improperly withheld or refused and not paid
either by the trust or by us pursuant to the relevant guarantee as described
under "Description of Guarantees," distributions on such capital securities will
continue to accrue at the then applicable rate, from the redemption date
originally established by the trust for such capital securities to the date such
redemption price is actually paid, in which case the actual payment date will be
the date fixed for redemption for purposes of calculating the redemption price.

    Subject to applicable law (including, without limitation, United States
federal securities law), we or our subsidiaries may at any time and from time to
time purchase outstanding capital securities by tender, in the open market or by
private agreement.

    Payment of the redemption price on the capital securities and any
distribution of corresponding junior subordinated debentures to holders of
capital securities will be made to the applicable recordholders as they appear
on the register for such capital securities on the relevant record date, which
shall be one business day prior to the relevant redemption date or liquidation
date, as applicable. However, if any capital securities are not in book-entry
form, the relevant record date for such capital securities will be a date at
least 15 days prior to the redemption date or liquidation date, as applicable,
as specified in the applicable prospectus supplement.

    If less than all of the capital securities and common securities issued by a
trust are to be redeemed on a redemption date, then the aggregate liquidation
amount of such capital securities and common securities to be redeemed shall be
allocated pro rata to the capital securities and the common securities based
upon the relative liquidation amounts of such classes. The property trustee will
select the particular capital securities to be redeemed on a pro rata basis not
more than 60 days prior to the redemption date from the outstanding capital
securities not previously called for redemption, using any method that the
property trustee deems fair and appropriate, including the selection for
redemption of portions of the liquidation amount of capital securities in the
minimum amounts that are specified in the applicable prospectus supplement. The
property trustee shall promptly notify the trust registrar in writing of the
capital securities selected for redemption and the liquidation amount to be
redeemed. For all purposes of each trust agreement, unless the context otherwise
requires, all provisions relating to the redemption of capital securities shall
relate, in the case of any capital securities redeemed or to be redeemed only in
part, to the portion of the aggregate liquidation amount of capital securities
which has been or is to be redeemed.

    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to the registered address of each holder of
trust securities to be redeemed.


                                      -26-


Subordination of Common Securities

    Payment of distributions on, and the redemption price of, each trust's
capital securities and common securities, as applicable, shall be made pro rata
based on the liquidation amount of such capital securities and common
securities. If, however, on any distribution date or redemption date a debenture
event of default shall have occurred and be continuing, no payment of any
distribution on, or redemption price of, any of the trust's common securities,
and no other payment on account of the redemption, liquidation or other
acquisition of such common securities, shall be made unless payment in full in
cash of all accumulated and unpaid distributions on all of the trust's
outstanding capital securities for all distribution periods terminating on or
prior thereto, or in the case of payment of the redemption price the full amount
of such redemption price on all of the trust's outstanding capital securities
then called for redemption, shall have been made or provided for, and all funds
available to the property trustee shall first be applied to the payment in full
in cash of all distributions on, or redemption price of, the trust's capital
securities then due and payable.

    In the case of any event of default under the applicable trust agreement
resulting from a debenture event of default, we as holder of such trust's common
securities, will be deemed to have waived any right to act with respect to any
such event of default under the applicable trust agreement until the effect of
all such events of default with respect to such capital securities have been
cured, waived or otherwise eliminated. Until all events of default under the
applicable trust agreement with respect to the capital securities have been so
cured, waived or otherwise eliminated, the property trustee shall act solely on
behalf of the holders of such capital securities and not on our behalf, and only
the holders of such capital securities will have the right to direct the
property trustee to act on their behalf.

Liquidation Distribution Upon Dissolution

    Pursuant to each trust agreement, each trust shall automatically dissolve
upon expiration of its term and shall dissolve on the first to occur of:

o   certain events of bankruptcy, dissolution or liquidation of State Street;

o   the distribution of a like amount of the corresponding junior subordinated
    debentures to the holders of its trust securities, if we, as depositor, have
    given written direction to the property trustee to dissolve such trust,
    subject to our having received prior approval of the Federal Reserve, if
    required;

o   redemption of all of the trust's capital securities as described under
    "--Redemption or Exchange-- Mandatory Redemption;" and

o   the entry of an order for the dissolution of the trust by a court of
    competent jurisdiction.

    If an early dissolution occurs as described above, the trustees will
liquidate the trust as expeditiously as possible by distributing, after
satisfaction of liabilities to creditors of such trust as provided by applicable
law, to the holders of such trust securities a like amount of the corresponding
junior subordinated debentures. If the property trustee determines that such
distribution is not practical, then the holders will be entitled to receive out
of the assets of the trust available for distribution to holders, after
satisfaction of liabilities to creditors of such trust as provided by applicable
law, an amount equal to, in the case of holders of capital securities, the
aggregate liquidation amount plus accrued and unpaid distributions to the date
of payment, the "LIQUIDATION DISTRIBUTION." If the trust has insufficient assets
available to pay in full the aggregate liquidation distribution, then the
amounts payable directly by such trust on its capital securities shall be paid
on a pro rata basis. The holder(s) of such trust's common securities will be
entitled to receive distributions upon any such liquidation pro rata with the
holders of its capital securities, except that if a debenture event of default
has occurred and is continuing, the capital securities shall have a priority
over the common securities.


                                      -27-


Events of Default; Notice

    Any one of the following events constitutes an event of default under the
trust agreement of a trust, a "TRUST EVENT OF DEFAULT," regardless of the reason
for such event of default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body:

o   the occurrence of a debenture event of default with respect to the
    corresponding junior subordinated debentures held by such trust, a
    "DEBENTURE EVENT OF DEFAULT" (please see "Description of Junior Subordinated
    Debentures--Debenture Events of Default"); or

o   the default by the property trustee in the payment of any distribution on
    any trust security of such trust when such becomes due and payable, and
    continuation of such default for a period of 30 days; or

o   the default by the property trustee in the payment of any redemption price
    of any trust security of such trust when such becomes due and payable; or

o   the default in the performance, or breach, in any material respect, of any
    covenant or warranty of the trustees in such trust agreement, other than a
    covenant or warranty of default in the performance of which or the breach of
    which is dealt with above, and continuation of such default or breach for a
    period of 90 days after there has been given, by registered or certified
    mail, to the defaulting trustee or trustees by the holders of at least 25%
    in aggregate liquidation amount of the outstanding capital securities of the
    applicable trust, a written notice specifying such default or breach and
    requiring it to be remedied and stating that such notice is a "Notice of
    Default" under such trust agreement; or

o   the occurrence of certain events of bankruptcy or insolvency with respect to
    the property trustee and our failure to appoint a successor property trustee
    within 90 days.

    Within the 90 days after the occurrence of any event of default actually
known to the property trustee, the property trustee will transmit notice of such
event of default to the holders of such trust's capital securities, the
administrative trustees and to us, as depositor, unless such event of default
shall have been cured or waived. We, as depositor, and the administrative
trustees are required to file annually with the property trustee a certificate
as to whether or not we or they are in compliance with all the conditions and
covenants applicable to us and to them under each trust agreement.

    If a debenture event of default with respect to the corresponding junior
subordinated debentures held by a trust has occurred and is continuing, the
capital securities of such trust shall have a preference over such trust's
common securities as described above. See "--Subordination of Common Securities"
and "--Liquidation Distribution Upon Termination." The existence of an event of
default does not entitle the holders of capital securities to accelerate the
maturity.

Removal of Trustees

    Unless a debenture event of default shall have occurred and be continuing,
any trustee may be removed at any time by the holder of the common securities.
If a debenture event of default has occurred and is continuing, the property
trustee and the Delaware trustee may be removed by the holders of a majority in
liquidation amount of the outstanding capital securities. In no event will the
holders of the capital securities have the right to vote to appoint, remove or
replace the administrative trustees, which voting rights are vested exclusively
in us, as the holder of the common securities. No resignation or removal of a
trustee and no appointment of a successor trustee shall be effective until the
acceptance of appointment by the successor trustee in accordance with the
provisions of the applicable trust agreement.


                                      -28-


Co-Trustees and Separate Property Trustee

    Unless an event of default shall have occurred and be continuing, at any
time or from time to time, for the purpose of meeting the legal requirements of
the Trust Indenture Act or of any jurisdiction in which any part of the trust
property may at the time be located, we, as the holder of the common securities,
and the administrative trustees shall have the power to appoint one or more
persons either to act as a co-trustee, jointly with the property trustee, of all
or any part of such trust property, or to act as separate trustee of any such
property, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such person or persons in such capacity any
property, title, right or power deemed necessary or desirable, subject to the
provisions of the applicable trust agreement. If a debenture event of default
has occurred and is continuing, the property trustee alone shall have power to
make such appointment.

Merger or Consolidation of Trustees

    Any person into which the property trustee, the Delaware trustee or any
administrative trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any person resulting from any merger,
conversion or consolidation to which such trustee shall be a party, or any
person succeeding to all or substantially all the corporate trust business of
such trustee, shall be the successor of such trustee under each trust agreement,
provided such person shall be otherwise qualified and eligible.

Mergers, Consolidations, Amalgamations or Replacements of the Trusts

    A trust may not merge with or into, consolidate, amalgamate, or be replaced
by, or convey, transfer or lease its properties and assets substantially as an
entirety to us or any other person, except as described below or as otherwise
described in the trust agreement. A trust may, at our request, with the consent
of the administrative trustees and without the consent of the holders of the
capital securities, the property trustee or the Delaware trustee, merge with or
into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease
its properties and assets substantially as an entirety to, a trust organized as
such under the laws of any state if:

o   such successor entity either:

    (1)  expressly assumes all of the obligations of such trust with respect to
         the capital securities, or

    (2)  substitutes for the capital securities other securities having
         substantially the same terms as the capital securities, the "SUCCESSOR
         SECURITIES," so long as the successor securities rank the same as the
         capital securities in priority with respect to distributions and
         payments upon liquidation, redemption and otherwise;

o   we expressly appoint a trustee of such successor entity possessing the same
    powers and duties as the property trustee as the holder of the corresponding
    junior subordinated debentures;

o   the successor securities are listed, or any successor securities will be
    listed upon notification of issuance, on any national securities exchange or
    other organization on which the capital securities are then listed, if any;

o   such merger, consolidation, amalgamation, replacement, conveyance, transfer
    or lease does not cause the capital securities to be downgraded by any
    nationally recognized statistical rating organization;

o   such merger, consolidation, amalgamation, replacement, conveyance, transfer
    or lease does not adversely affect the rights, preferences and privileges of
    the holders of the capital securities (including any successor securities)
    in any material respect;

o   such successor entity has a purpose substantially identical to that of the
    trust;


                                      -29-


o   prior to such merger, consolidation, amalgamation, replacement, conveyance,
    transfer or lease, we have received an opinion from independent counsel to
    the trust experienced in such matters to the effect that:

    (1)  such merger, consolidation, amalgamation, replacement, conveyance,
         transfer or lease does not adversely affect the rights, preferences and
         privileges of the holders of the capital securities (including any
         successor securities) in any material respect, and

    (2)  following such merger, consolidation, amalgamation, replacement,
         conveyance, transfer or lease, neither the trust nor such successor
         entity will be required to register as an investment company under the
         Investment Company Act of 1940, as amended, the "INVESTMENT COMPANY
         ACT"; and

o   we or any permitted successor or assignee owns all of the common securities
    of such successor entity and guarantees the obligations of such successor
    entity under the successor securities at least to the extent provided by the
    guarantee.

    Notwithstanding the foregoing, a trust may not, except with the consent of
holders of 100% in liquidation amount of the capital securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to any other entity or
permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger, replacement, conveyance,
transfer or lease would cause the trust or the successor entity to be classified
as other than a grantor trust for United States federal income tax purposes.

Voting Rights; Amendment of Each Trust Agreement

    Except as provided below and under "Description of Guarantees--Amendments
and Assignment" and as otherwise required by law and the applicable trust
agreement, the holders of the capital securities will have no voting rights.

    We and the administrative trustees may amend each trust agreement without
the consent of the holders of the capital securities, unless such amendment will
materially and adversely affect the interests of any holder of capital
securities:

o   to cure any ambiguity, correct or supplement any provisions in such trust
    agreement that may be inconsistent with any other provision, or to make any
    other provisions with respect to matters or questions arising under such
    trust agreement, which may not be inconsistent with the other provisions of
    such trust agreement; or

o   to modify, eliminate or add to any provisions of such trust agreement to
    such extent as shall be necessary to ensure that the trust will be
    classified for United States federal income tax purposes as a grantor trust
    at all times that any trust securities are outstanding or to ensure that the
    Trust will not be required to register as an "investment company" under the
    Investment Company Act.

Any such amendments will become effective when notice thereof is given to the
holders of trust securities.

    We, the administrative trustees and the property trustee may amend each
trust agreement with:

o   the consent of holders representing not less than a majority (based upon
    liquidation amounts) of the outstanding trust securities; and

o   receipt by the trustees of an opinion of counsel to the effect that such
    amendment or the exercise of any power granted to the trustees in accordance
    with such amendment will not affect the trust's status as a grantor trust
    for United States federal income tax purposes or the trust's exemption from
    status as an "investment company" under the Investment Company Act.


                                      -30-


    Without the consent of each holder of trust securities, the trust agreement
may not be amended to:

o   change the amount or timing of any distribution required to be made in
    respect of the trust securities as of a specified dates; or

o   restrict the right of a holder of trust securities to institute suit for the
    enforcement of any such payment on or after such date.

    So long as the property trustee holds any corresponding junior subordinated
debentures, the trustees may not, without obtaining the prior approval of the
holders of a majority in aggregate liquidation amount of all outstanding capital
securities:

o   direct the time, method and place of conducting any proceeding for any
    remedy available to the debenture trustee, or executing any trust or power
    conferred on the property trustee with respect to such corresponding junior
    subordinated debentures;

o   waive any past default that is waivable under the junior subordinated
    indenture;

o   exercise any right to rescind or annul a declaration that the principal of
    all the corresponding junior subordinated debentures is due and payable; or

o   consent to any amendment, modification or termination of the junior
    subordinated indenture or such corresponding junior subordinated debentures,
    where such consent shall be required.

    If a consent under the junior subordinated indenture would require the
consent of each holder of corresponding junior subordinated debentures affected
thereby, no such consent may be given by the property trustee without the prior
consent of each holder of the corresponding capital securities. The trustees may
not revoke any action previously authorized or approved by a vote of the holders
of the capital securities except by subsequent vote of the holders of the
capital securities. The property trustee will notify each holder of the capital
securities of any notice of default with respect to the corresponding junior
subordinated debentures. In addition to obtaining the foregoing approvals of the
holders of the capital securities, prior to taking any of the foregoing actions,
the trustees will obtain an opinion of counsel experienced in such matters to
the effect that such action would not cause the trust to be classified as other
than a grantor trust for United States federal income tax purposes.

    Any required approval of holders of capital securities may be given at a
meeting of holders of capital securities convened for such purpose or pursuant
to written consent. The property trustee will cause a notice of any meeting at
which holders of capital securities are entitled to vote, or of any matter upon
which action by written consent of such holders is to be taken, to be given to
each holder of record of capital securities in the manner set forth in each
trust agreement.

    No vote or consent of the holders of capital securities will be required for
a trust to redeem and cancel its capital securities in accordance with the
applicable trust agreement.

    Notwithstanding that holders of capital securities are entitled to vote or
consent under any of the circumstances described above, any of the capital
securities that are owned by us or our affiliates or the trustees or any of
their affiliates, shall, for purposes of such vote or consent, be treated as if
they were not outstanding.

Payment and Paying Agency

    Payments on the capital securities shall be made to the depositary, which
shall credit the relevant accounts at the depositary on the applicable
distribution dates. If any trust's capital securities are not held by the
depositary, such payments shall be made by check mailed to the address of the
holder as such address shall appear on the register.


                                      -31-


    Unless otherwise specified in the applicable prospectus supplement, the
paying agent shall initially be the property trustee and any co-paying agent
chosen by the property trustee and acceptable to us and to the administrative
trustees. The paying agent shall be permitted to resign as paying agent upon 30
days' written notice to us and to the property trustee. In the event that the
property trustee shall no longer be the paying agent, the administrative
trustees will appoint a successor, which will be a bank or trust company
acceptable to the administrative trustees and to us, to act as paying agent.

Registrar and Transfer Agent

    Unless otherwise specified in the applicable prospectus supplement, the
property trustee will act as registrar and transfer agent for the capital
securities.

    Registration of transfers of capital securities will be effected without
charge by or on behalf of each trust, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The trusts will not be required to register or cause to be registered
the transfer of their capital securities after such capital securities have been
called for redemption.

Information Concerning the Property Trustee

    The property trustee, other than during the occurrence and continuance of an
event of default, undertakes to perform only the duties that are specifically
set forth in each trust agreement. After an event of default, the property
trustee must exercise the same degree of care and skill as a prudent individual
would exercise or use in the conduct of his or her own affairs. Subject to this
provision, the property trustee is under no obligation to exercise any of the
powers vested in it by the applicable trust agreement at the request of any
holder of capital securities unless offered indemnity satisfactory to it by such
holder against the costs, expenses and liabilities that might be incurred. If no
event of default has occurred and is continuing and the property trustee is
required to decide between alternative causes of action, construe ambiguous
provisions in the applicable trust agreement or is unsure of the application of
any provision of the applicable trust agreement, and the matter is not one on
which holders of capital securities are entitled under such trust agreement to
vote, then the property trustee will take any action that we direct. If we do
not provide direction, the property trustee may take any action that it deems
advisable and in the best interests of the holders of the trust securities and
will have no liability except for its own bad faith, negligence or wilful
misconduct.

Trust Expenses

    Pursuant to the trust agreement of each trust, we, as depositor, agree to
pay:

o   all debts and other obligations of each trust (other than with respect to
    the capital securities);

o   all costs and expenses of each trust (including costs and expenses relating
    to the organization of each trust, the fees and expenses of the trustees and
    the cost and expenses relating to the operation of each trust); and

o   any and all taxes and costs and expenses with respect thereto (other than
    United States withholding taxes) to which each trust might become subject.

Governing Law

    Each trust agreement will be governed by and construed in accordance with
the laws of Delaware.


                                      -32-


Miscellaneous

    The administrative trustees are authorized and directed to conduct the
affairs of and to operate the trusts in such a way that no trust will be
required to register as an "investment company" under the Investment Company Act
or characterized as other than a grantor trust for United States federal income
tax purposes. The administrative trustees are authorized and directed to conduct
their affairs so that the corresponding junior subordinated debentures will be
treated as indebtedness of State Street for United States federal income tax
purposes. In this connection, we and the administrative trustees are authorized
to take any action, not inconsistent with applicable law, the certificate of
trust of each trust or each trust agreement, that we and the administrative
trustees determine to be necessary or desirable to achieve such end, as long as
such action does not materially and adversely affect the interests of the
holders of the related capital securities.

    Holders of the capital securities have no preemptive or similar rights.

    No trust may borrow money or issue debt or mortgage or pledge any of its
assets.

COMMON SECURITIES

    In connection with the issuance of capital securities, each trust will issue
one series of common securities having the terms, including distributions,
redemption, voting and liquidation rights, set forth in the applicable
prospectus supplement. Except for voting rights, the terms of the common
securities will be substantially identical to the terms of the capital
securities. The common securities will rank equally, and payments will be made
on the common securities pro rata, with the capital securities, except that,
upon an event of default, the rights of the holders of the common securities to
payment in respect of distributions and payments upon liquidation, redemption
and otherwise will be subordinated to the rights of the holders of the capital
securities. Except in limited circumstances, the common securities of a trust
carry the right to vote to appoint, remove or replace any of the trustees of
that trust. We will own, directly or indirectly, all of the common securities of
each trust.

DESCRIPTION OF THE CAPITAL SECURITIES GUARANTEES

    Set forth below is a summary of information concerning the capital
securities guarantees that we will execute and deliver for the benefit of the
holders of capital securities. Each capital securities guarantee will be
qualified as an indenture under the Trust Indenture Act. Bank One Trust Company,
N.A. will act as the guarantee trustee for purposes of the Trust Indenture Act.
The terms of each capital securities guarantee will be those set forth in the
capital securities guarantee and those made part of the capital securities
guarantee by the Trust Indenture Act. The summary of the material terms of the
capital securities guarantees is not intended to be complete and is qualified in
all respects by the provisions of the form of capital securities guarantee which
is filed as an exhibit to the registration statement which contains this
prospectus, and the Trust Indenture Act. The guarantee trustee will hold each
capital securities guarantee for the benefit of the holders of the capital
securities of the applicable trust.

General

    Pursuant to and to the extent set forth in the capital securities guarantee,
we will irrevocably and unconditionally agree to pay in full to the holders of
the trust securities, except to the extent paid by the trust, as and when due,
regardless of any defense, right of set-off or counterclaim which the trust may
have or assert, the following payments, which are referred to as "GUARANTEE
PAYMENTS," without duplication:

o   any accrued and unpaid distributions that are required to be paid on the
    capital securities, to the extent the trust has funds available for
    distributions;

o   the redemption price, plus all accrued and unpaid distributions, to the
    extent the trust has funds available for redemptions, relating to any
    capital securities called for redemption by the trust; and


                                      -33-


o   upon a voluntary or involuntary dissolution, winding-up or termination of
    the trust, other than in connection with the distribution of junior
    subordinated debentures to the holders of capital securities or the
    redemption of all of the capital securities, the lesser of:

    (1)  the aggregate of the liquidation amount and all accrued and unpaid
         distributions on the capital securities to the date of payment; and

    (2)  the amount of assets of the trust remaining for distribution to holders
         of the capital securities in liquidation of the trust.

    The redemption price and liquidation amount will be fixed at the time the
capital securities are issued.

    Our obligation to make a guarantee payment may be satisfied by direct
payment of the required amounts to the holders of capital securities or by
causing the trust to pay such amounts to such holders.

    The capital securities guarantees will not apply to any payment of
distributions except to the extent a trust shall have funds available for such
payments. If we do not make interest payments on the junior subordinated
debentures purchased by a trust, the trust will not pay distributions on the
capital securities and will not have funds available for such payments. Please
see "--Status of the Guarantees." Because we are a holding company, our rights
to participate in the assets of any of our subsidiaries upon the subsidiary's
liquidation or reorganization will be subject to the prior claims of the
subsidiary's creditors except to the extent that we may ourselves be a creditor
with recognized claims against the subsidiary. Except as otherwise provided in
the applicable prospectus supplement, the capital securities guarantees do not
limit the incurrence or issuance by us of other secured or unsecured debt.

    The capital securities guarantees, when taken together with our obligations
under the junior subordinated debentures, the indentures and the trust
agreements, including our obligations to pay costs, expenses, debts and
liabilities of the trusts, other than those relating to trust securities, will
provide a full and unconditional guarantee on a subordinated basis of payments
due on the capital securities.

    We have also agreed separately to irrevocably and unconditionally guarantee
the obligations of the trusts with respect to the common securities to the same
extent as the capital securities guarantees, except that upon an event of
default under the indenture, holders of capital securities shall have priority
over holders of common securities with respect to distributions and payments on
liquidation, redemption or otherwise.

Status of the Guarantees

    Each capital security guarantee will be unsecured and will rank:

o   subordinate and junior in right of payment to all our other liabilities in
    the same manner as the junior subordinated indentures; and

o   equally with all other capital security guarantees that we issue.

    Each capital securities guarantee will constitute a guarantee of payment and
not of collection. This means that the guaranteed party may sue the guarantor to
enforce its rights under the guarantee without suing any other person or entity.
Each guarantee will be held for the benefit of the holders of the related trust
securities. Each capital trust guarantee will be discharged only by payment of
the guarantee payments in full to the extent not paid by the trust or upon the
junior subordinated debentures.

Amendments and Assignment


                                      -34-


    The capital securities guarantee may be amended only with the prior approval
of the holders of not less than a majority in aggregate liquidation amount of
the outstanding capital securities. No vote will be required, however, for any
changes that do not adversely affect the rights of holders of capital
securities. All guarantees and agreements contained in the capital securities
guarantee will bind our successors, assignees, receivers, trustees and
representatives and will be for the benefit of the holders of the capital
securities then outstanding.

Termination of the Guarantees

    Each capital securities guarantee will terminate upon full payment of the
redemption price of all capital securities, upon distribution of the junior
subordinated debentures to the holders of the trust securities or upon full
payment of the amounts payable in accordance with the trust agreement upon
liquidation of such trust. Each capital securities guarantee will continue to be
effective or will be reinstated, as the case may be, if at any time any holder
of capital securities must restore payment of any sums paid under the capital
securities or the capital securities guarantee.

Events of Default

    An event of default under a capital securities guarantee will occur if we
fail to perform any payment or other obligations under the capital securities
guarantee.

    The holders of a majority in liquidation amount of the capital securities
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the guarantee trustee in respect of the capital
securities guarantee or to direct the exercise of any trust or power conferred
upon the guarantee trustee under the capital securities guarantee. Any holder of
capital securities may institute a legal proceeding directly against us to
enforce the guarantee trustee's rights and our obligations under the capital
securities guarantee, without first instituting a legal proceeding against the
relevant trust, the guarantee trustee or any other person or entity.

    As guarantor, we are required to file annually with the guarantee trustee a
certificate as to whether or not we are in compliance with all applicable
conditions and covenants applicable under the capital securities guarantee.

Information Concerning the Guarantee Trustee

    Prior to the occurrence of a default relating to a capital securities
guarantee, the guarantee trustee is required to perform only the duties that are
specifically set forth in the capital securities guarantee. Following the
occurrence of a default, the guarantee trustee will exercise the same degree of
care as a prudent individual would exercise in the conduct of his or her own
affairs. Provided that the foregoing requirements have been met, the guarantee
trustee is under no obligation to exercise any of the powers vested in it by a
capital securities guarantee at the request of any holder of capital securities,
unless offered indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred thereby.

    We and our affiliates maintain certain accounts and other banking
relationships with the guarantee trustee and its affiliates in the ordinary
course of business.

Governing Law

     The capital securities guarantees will be governed by and construed in
accordance with the internal laws of the state of New York.

RELATIONSHIP AMONG THE CAPITAL SECURITIES, THE CORRESPONDING JUNIOR
SUBORDINATED DEBENTURES AND THE CAPITAL SECURITIES GUARANTEES


                                      -35-


    As set forth in the trust agreements, the sole purpose of the trusts is to
issue the trust securities and to invest the proceeds in the junior subordinated
debentures.

    As long as payments of interest and other payments are made when due on the
junior subordinated debentures, those payments will be sufficient to cover the
distributions and payments due on the trust securities. This is due to the
following factors:

o   the aggregate principal amount of junior subordinated debentures will be
    equal to the sum of the aggregate stated liquidation amount of the trust
    securities;

o   the interest rate and the interest and other payment dates on the junior
    subordinated debentures will match the distribution rate and distribution
    and other payment dates for the trust securities;

o   under the junior subordinated indenture, we will pay, and the trusts will
    not be obligated to pay, directly or indirectly, all costs, expenses, debts
    and obligations of the trusts, other than those relating to the trust
    securities; and

o   the trust agreements further provide that the trustees may not cause or
    permit the trusts to engage in any activity that is not consistent with the
    purposes of the trusts.

    To the extent that funds are available, we guarantee payments of
distributions and other payments due on the capital securities to the extent
described in this prospectus. If we do not make interest payments on the junior
subordinated debentures, the trust will not have sufficient funds to pay
distributions on the capital securities. Each capital securities guarantee is a
subordinated guarantee in relation to the capital securities. The capital
securities guarantee does not apply to any payment of distributions unless and
until the trust has sufficient funds for the payment of such distributions.
Please see "Description of the Capital Securities Guarantees."

    We have the right to set off any payment that we are otherwise required to
make under the junior subordinated indenture with any payment that we have
previously made or are concurrently on the date of such payment making under a
related guarantee.

    The capital securities guarantees cover the payment of distributions and
other payments on the capital securities only if and to the extent that we have
made a payment of interest or principal or other payments on the junior
subordinated debentures. The capital securities guarantees, when taken together
with our obligations under the junior subordinated debentures and the indenture
and our obligations under the trust agreement, will provide a full and
unconditional guarantee of distributions, redemption payments and liquidation
payments on the capital securities.

    If we fail to make interest or other payments on the junior subordinated
debentures when due, taking account of any extension period, the trust
agreements allow the holders of the capital securities to direct the property
trustee to enforce its rights under the junior subordinated debentures. If the
property trustee fails to enforce these rights, any holder of capital securities
may directly sue us to enforce such rights without first suing the property
trustee or any other person or entity. Please see "Description of the Capital
Securities--Book Entry Issuance" and "--Voting Rights."

    A holder of capital securities may institute a direct action if a trust
agreement event of default has occurred and is continuing and such event is
attributable to our failure to pay interest or principal on the junior
subordinated debentures when due. A direct action may be brought without first
(1) directing the property trustee to enforce the terms of the junior
subordinated debentures or (2) suing us to enforce the property trustee's rights
under the junior subordinated debentures. In connection with such direct action,
we will be subrogated to the rights of such holder of capital securities under
the trust agreement to the extent of any payment made by us to such holder of
capital securities. Consequently, we will be entitled to payment of amounts that
a holder of capital securities receives in


                                      -36-


respect of an unpaid distribution to the extent that such holder receives or has
already received full payment relating to such unpaid distribution from a trust.

    We acknowledge that the guarantee trustee will enforce the capital
securities guarantees on behalf of the holders of the capital securities. If we
fail to make payments under the capital securities guarantees, the holders of
the capital securities may direct the guarantee trustee to enforce its rights
thereunder. If the guarantee trustee fails to enforce the capital securities
guarantees, any holder of capital securities may directly sue us to enforce the
guarantee trustee's rights under the capital securities guarantees. Such holder
need not first sue the trust, the guarantee trustee, or any other person or
entity. A holder of capital securities may also directly sue us to enforce such
holder's right to receive payment under the capital securities guarantees. Such
holder need not first (1) direct the guarantee trustee to enforce the terms of
the capital securities guarantee or (2) sue the trust or any other person or
entity.

    A default or event of default under any of our senior debt would not
constitute a default or event of default under the junior subordinated
indenture. However, in the event of payment defaults under, or acceleration of,
our senior debt, the subordination provisions of the junior subordinated
indenture provide that no payments may be made in respect of the corresponding
junior subordinated debentures until such senior debt has been paid in full or
any payment default thereunder has been cured or waived. Failure to make
required payments on any series of corresponding junior subordinated debentures
would constitute an event of default under the junior subordinated indenture.

    We and the trusts believe that the above mechanisms and obligations, taken
together, are equivalent to a full and unconditional guarantee by us of payments
due on the capital securities. Please see "Description of the Capital Securities
Guarantees--General."

Limited Purpose of Trusts

    Each trust's capital securities evidence a beneficial interest in such
trust, and each trust exists for the sole purpose of issuing its capital
securities and common securities and investing the proceeds in corresponding
junior subordinated debentures. A principal difference between the rights of a
holder of a capital security and a holder of a corresponding junior subordinated
debenture is that a holder of a corresponding junior subordinated debenture is
entitled to receive from us the principal amount of and interest accrued on
corresponding junior subordinated debentures held, while a holder of capital
securities is entitled to receive distributions from such trust (or from us
under the applicable guarantee) if and to the extent such trust has funds
available for the payment of such distributions.

Rights Upon Dissolution

    Upon any voluntary or involuntary dissolution, winding up or liquidation of
any trust involving the liquidation of the corresponding junior subordinated
debentures, after satisfaction of liabilities to creditors of the trust, the
holders of the related capital securities will be entitled to receive, out of
the assets held by such trust, the liquidation distribution in cash. Please see
"Description of Capital Securities--Liquidation Distribution Upon Termination."
Upon any voluntary or involuntary liquidation or bankruptcy of State Street, the
property trustee, as holder of the corresponding junior subordinated debentures,
would be a subordinated creditor of State Street, subordinated in right of
payment to all senior debt as set forth in the junior subordinated indenture,
but entitled to receive payment in full of principal and interest before any of
our stockholders receive distributions. Since we are the guarantor under each
guarantee and have agreed to pay for all costs, expenses and liabilities of each
trust, other than the trusts' obligations to the holders of its capital
securities, the positions of a holder of such capital securities and a holder of
such corresponding junior subordinated debentures relative to other creditors
and to our stockholders in the event of liquidation or bankruptcy are expected
to be substantially the same.


                                      -37-


GLOBAL SECURITIES

General

    The capital securities may be issued in whole or in part in the form of one
or more fully registered global offered securities, each a "GLOBAL SECURITY,"
that will be deposited with, or on behalf of, a depository which unless
otherwise indicated in the applicable prospectus supplement for such series will
be DTC. Global capital securities may be issued in either temporary or permanent
form. Unless and until it is exchanged in whole or in part for offered
securities in definitive form, a global security may not be transferred except
as a whole by the depository for such global security to a nominee of such
depository or by a nominee of such depository to such depository or another
nominee of such depository or by such depository or any such nominee to a
successor of such depository or a nominee of such successor or in the manner
provided in the final paragraph under this heading.

    The specific terms of the depository arrangement with respect to any capital
securities will be described in the applicable prospectus supplement. We
anticipate that the following provisions will apply to all depository
arrangements.

    Upon the issuance of a global security and the deposit of such global
capital security with or on behalf of the depository, the depository for such
global security will credit, on its book-entry registration and transfer system,
the respective aggregate liquidation amounts, of the capital securities
represented by such global security to the accounts of persons that have
accounts with such depository, each such person a "PARTICIPANT," which may
include Euroclear and Cedel. The accounts to be credited shall be designated by
the dealers, underwriters or agents participating in the distribution of such
capital securities or by us if we have offered and sold such capital securities
directly. Ownership of beneficial interests in a global security will be limited
to participants or persons that may hold interest through participants.

    Ownership of a beneficial interest in such global security will be shown on,
and the transfer of that ownership will be effected only through, records
maintained by the depository for such global security (with respect to interests
of participants) or by participants or persons that hold through participants
(with respect to interests of persons other than participants). The laws of some
states require that certain purchasers of securities take physical delivery of
such securities in definitive form. Such limits and such laws may impair the
ability to own, transfer or pledge beneficial interests in a global security.

    So long as the depository for a global security, or its nominee, is the
holder of such global security, such depository or such nominee, as the case may
be, will be considered the sole owner or holder of the capital securities
represented by such global security for all purposes under the applicable trust
agreement. Except as set forth below, owners of beneficial interests in a global
security will not be entitled to have capital securities of the series
represented by such global security registered in their names, will not receive
or be entitled to receive physical delivery of offered securities of such series
in definitive form and will not be considered the owners or holders thereof
under the applicable trust agreement. Accordingly, each person owning a
beneficial interest in a global security must rely on the procedures of the
depository for such global security and, if such person is not a participant, on
the procedures of the participant through which such person owns its interest,
to exercise any rights of a holder under the applicable indenture. We understand
that under existing industry practices, if we request any action of holders or
if an owner of a beneficial interest in a global security desires to give or
take any action which a holder is entitled to give or take under the applicable
indenture, the depository for such global security would authorize the
participants holding the relevant beneficial interest to give or take such
action, and such participants would authorize beneficial owners owning through
such participants to give or take such action or would otherwise act upon the
instructions of beneficial owners holding through them.

    Payments of principal of or premium, if any, and interest, if any, on
capital securities represented by a global security registered in the name of a
depository or its nominee will be made to such depository or its nominee, as the
case may be, as the registered owner or the holder of the global security
representing such capital securities. None of


                                      -38-


State Street, the trustee for such offered securities, any paying agent for such
offered securities, the property trustee or the securities registrar, as
applicable, will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a global security for such offered securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

    We expect that the depository for a series of capital securities or its
nominee, upon receipt of any payment of liquidation amount, redemption price,
premium or distributions in respect of a permanent global capital security
representing any of such capital securities, immediately will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interest in the aggregate liquidation amount of such
global capital security for such capital securities as shown on the records of
such depositary or its nominee. We also expect that payments by participants to
owners of beneficial interests in such global security held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name," and will be the responsibility of such
participants.

    Unless otherwise specified in the applicable prospectus supplement, if a
depository for a series of capital securities is at any time unwilling, unable
or ineligible to continue as depository and a successor depository is not
appointed by the trust within 90 days, the trust will issue individual capital
securities of such series in exchange for the global capital security
representing such series of capital securities. In addition, the trust may at
any time and in its sole discretion, subject to any limitations described in the
prospectus supplement relating to such capital securities, determine not to have
any capital securities of such series represented by one or more global capital
securities and, in such event, will issue individual capital securities of such
series in exchange for the global capital security or securities representing
such series of capital securities. Further, if the trust so specifies with
respect to the capital securities of a series, an owner of a beneficial interest
in a global capital security representing capital securities of such series may,
on terms acceptable to the trust, the property trustee and the depository for
such global capital security, receive individual capital securities of such
series in exchange for such beneficial interests, subject to any limitations
described in the prospectus supplement relating to such capital securities. In
any such instance, an owner of a beneficial interest in a global capital
security will be entitled to a physical delivery of individual capital
securities of the series represented by such global capital security equal in
principal amount to such beneficial interest and to have such capital securities
registered in its name.

Book-Entry Issuance

    DTC will act as securities depository for all of the capital securities,
including the junior subordinated debentures, unless otherwise referred to in
the prospectus supplement. The capital securities will be issued only as
fully-registered securities registered in the name of Cede & Co. (DTC's
nominee). One or more fully-registered global certificates will be issued for
the capital securities of each trust, representing in the aggregate the total
number of such trust's capital securities and will be deposited with the
property trustee as custodian for DTC.

    DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants deposit with DTC. DTC also facilitates
the settlement among participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in participants' accounts, thereby eliminating the need for physical
movement of securities certificates. "DIRECT PARTICIPANTS" include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. DTC is owned by a number of its direct participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain custodial relationships with direct
participants, either directly or indirectly. The rules applicable to DTC and its
participants are on file with the Commission.


                                      -39-


    Purchases of capital securities within the DTC system must be made by or
through direct participants, which will receive a credit for the capital
securities on DTC's records. The ownership interest of each actual purchaser of
each capital security, each a "BENEFICIAL OWNER," is in turn to be recorded on
the direct and indirect participants' records, including Euroclear and Cedel.
Beneficial owners will not receive written confirmation from DTC of their
purchases, but beneficial owners are expected to receive written confirmations
providing details of the transactions, as well as periodic statements of their
holdings, from the direct or indirect participants through which the beneficial
owners purchased capital securities or junior subordinated debentures. Transfers
of ownership interests in the capital securities are to be accomplished by
entries made on the books of participants acting on behalf of beneficial owners.
Beneficial owners will not receive certificates representing their ownership
interests in capital securities, except in the event that use of the book-entry
system for the capital securities of such trust is discontinued.

    Transfers between participants will be effected in accordance with DTC's
procedures and will be settled in same- day funds. Transfers between
participants in Euroclear and Cedel will be effected in the ordinary way in
accordance with their respective rules and operating procedures.

    Cross-market transfers between participants, on the one hand, and Euroclear
participants or Cedel participants, on the other hand, will be effected in DTC
in accordance with DTC's rules on behalf of Euroclear or Cedel, as the case may
be, by its respective Depository; however, such cross-market transaction will
require delivery of instructions to Euroclear or Cedel, as the case may be, by
the counterparty in such system in accordance with the rules and procedures and
within the established deadlines (Brussels time) of such system. Euroclear or
Cedel, as the case may be, will, if the transaction meets its settlement
requirements, deliver instructions to its respective depository to take action
to effect final settlement on its behalf by delivering or receiving interests in
the capital securities in DTC, and making or receiving payment in accordance
with normal procedures and Cedel participants may not deliver instructions
directly to the depositaries for Euroclear or Cedel.

    Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in a capital security from a
participant in DTC will be credited, and any such crediting will be reported to
the relevant Euroclear participant or Cedel participant, during the securities
settlement processing day (which must be a business day for Euroclear and Cedel,
as the case may be) immediately following the DTC settlement date. Cash received
in Euroclear or Cedel as a result of sales of interests in a capital security by
or through a Euroclear or Cedel participant to a participant in DTC will be
received with value on the DTC settlement date but will be available in the
relevant Euroclear or Cedel cash account only as of the business day for
Euroclear or Cedel following the DTC settlement date.

    DTC has no knowledge of the actual beneficial owners of the capital
securities; DTC's records reflect only the identity of the direct participants
to whose accounts such capital securities are credited, which may or may not be
the beneficial owners. The participants will remain responsible for keeping
account of their holdings on behalf of their customers.

    Conveyance of notices and other communications by DTC to direct
participants, by direct participants to indirect participants, and by direct
participants and indirect participants to beneficial owners and the voting
rights of direct participants, indirect participants and beneficial owners will
be governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

    Redemption notices will be sent to Cede & Co. as the registered holder of
the capital securities. If less than all of a trust's capital securities are
being redeemed, DTC's current practice is to determine by lot the amount of the
interest of each direct participant to be redeemed.

    Although voting with respect to the capital securities is limited to the
holders of record of the capital securities in those instances in which a vote
is required, neither DTC nor Cede & Co. will itself consent or vote with respect
to the capital securities. Under its usual procedures, DTC would mail an omnibus
proxy to the relevant trustee as soon as possible after the record date. The
omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct


                                      -40-


participants to whose accounts such capital securities are credited on the
record date (identified in a listing attached to the omnibus proxy).

    Distribution payments on the capital securities will be made by the relevant
trustee to DTC. DTC's practice is to credit direct participants' accounts on the
relevant payment date in accordance with their respective holdings shown on
DTC's records unless DTC has reason to believe that it will not receive payments
on such payment date. Payments by participants to beneficial owners will be
governed by standing instructions and customary practices and will be the
responsibility of such participant and not of DTC, the relevant trustee, the
trust thereof or State Street, subject to any statutory or regulatory
requirements as may be in effect from time to time. Payment of distributions to
DTC is the responsibility of the relevant trustee, and disbursements of such
payments to the beneficial owners is the responsibility of direct and indirect
participants.

    DTC may discontinue providing its services as securities depository with
respect to any of the capital securities at any time by giving reasonable notice
to the relevant trustee and State Street. In the event that a successor
securities depository is not obtained, definitive capital security or junior
subordinated debenture certificates representing such capital securities are
required to be printed or delivered. State Street, at its option, may decide to
discontinue use of the system of book-entry transfers through DTC (or a
successor depository). After an event of default, the holders of a majority in
liquidation preference of capital securities may determine to discontinue the
system of book-entry transfers through DTC. In any event, definitive
certificates for such capital securities will be printed and delivered.

    The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we and the trusts believe to be accurate,
but we and the trusts assume no responsibility for the accuracy thereof. Neither
we nor the trusts have any responsibility for the performance by DTC or its
participants of their respective obligations or under the rules and procedures
governing their respective operations.

PLAN OF DISTRIBUTION

    We and the trusts may sell securities:

o   to the public through a group of underwriters managed or co-managed by, one
    or more underwriters, which may be affiliates;

o   through one or more agents, which may be affiliates; or directly to
    purchasers.

    The distribution of the securities may be effected from time to time in one
or more transactions:

o   at a fixed price, or prices, which may be changed from time to time;

o   at market prices prevailing at the time of sale;

o   at prices related to such prevailing market prices; or

o   at negotiated prices.

    Each prospectus supplement will describe the method of distribution of the
securities and any applicable restrictions.

    The prospectus supplement with respect to the securities of a particular
series will describe the terms of the offering of the securities, including the
following:

o   the name of the agent or the name or names of any underwriters;


                                      -41-


o   the public offering or purchase price;

o   any discounts and commissions to be allowed or paid to the agent or
    underwriters;

o   all other items constituting underwriting compensation;

o   any discounts and commissions to be allowed or paid to dealers; and

o   any exchanges on which the securities will be listed.

    Any trust, in connection with its offering of capital securities, may grant
to the underwriters an option to purchase additional capital securities to cover
over-allotments, if any, at the initial public offering price (with an
additional underwriting commission), as may be set forth in the accompanying
prospectus supplement. If the trust grants an over-allotment option, the terms
of this over-allotment option will be set forth in the prospectus supplement for
the capital securities.

    Only the agents or underwriters named in the prospectus supplement are
agents or underwriters in connection with the securities being offered.

    We may agree to enter into an agreement to indemnify the agents and the
several underwriters against certain civil liabilities, including liabilities
under the Securities Act or to contribute to payments the agents or the
underwriters may be required to make.

    If so indicated in the applicable prospectus supplement, we will authorize
underwriters or other persons acting as our agents to solicit offers by certain
institutions to purchase capital securities from us pursuant to delayed delivery
contracts providing for payment and delivery on the date stated in the
prospectus supplement. Each contract will be for an amount not less than, and
the aggregate amount of securities sold pursuant to such contracts shall not be
less nor more than, the respective amounts stated in the prospectus supplement.
Institutions with whom the contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and other institutions, but
shall in all cases be subject to our approval. Delayed delivery contracts will
not be subject to any conditions except that:

o   the purchase by an institution of the capital securities or warrants covered
    under that contract shall not at the time of delivery be prohibited under
    the laws of the jurisdiction to which that institution is subject; and

o   if the capital securities or warrants are also being sold to underwriters
    acting as principals for their own account, the underwriters shall have
    purchased such debt securities or warrants not sold for delayed delivery.
    The underwriters and other persons acting as our agents will not have any
    responsibility in respect of the validity or performance of delayed delivery
    contracts.

    Certain of the underwriters and their associates and affiliates may be
customers of, have borrowing relationships with, engage in other transactions
with, and/or perform services, including investment banking services, for, us or
one or more of our affiliates in the ordinary course of business.

    Certain of the underwriters may use this prospectus and the accompanying
prospectus supplement for offers and sales related to market-making transactions
in the securities. These underwriters may act as principal or agent in these
transactions, and the sales will be made at prices related to prevailing market
prices at the time of sale.

    The securities will be new issues of securities and will have no established
trading market. The securities may or may not be listed on a national securities
exchange or the Nasdaq National Market. We can make no assurance as to the
liquidity of or the existence of trading markets for any of the securities.


                                      -42-


                             VALIDITY OF SECURITIES

    Unless the applicable prospectus supplement indicates otherwise, certain
matters of Delaware law relating to the validity of the capital securities, the
enforceability of the applicable trust agreement and the creation of each trust
will be passed upon for State Street and for the trusts by Richards, Layton &
Finger, special Delaware counsel to State Street and the trusts. Unless the
applicable prospectus supplement indicates otherwise, certain legal matters will
be passed upon by Ropes & Gray for State Street and the trusts and for the
underwriters by Cravath, Swaine & Moore. Ropes & Gray will rely as to all
matters of New York law on the opinion of Cravath, Swaine & Moore. Truman S.
Casner, a partner of Ropes & Gray, is a director of State Street. Mr. Casner
owns beneficially a total of 17,204 shares of common stock of State Street.
Ropes & Gray performs services for State Street from time to time. Ropes & Gray
and Cravath, Swaine & Moore will rely on Richards, Layton & Finger as to all
matters of Delaware law.

                                     EXPERTS

      The consolidated financial statements of State Street Corporation
incorporated by reference in State Street Corporation's Annual Report (Form
10-K) for the year ended December 31, 1999, have been audited by Ernst & Young
LLP, independent auditors, as set forth in their report thereon incorporated by
reference therein and incorporated herein by reference. Such consolidated
financial statements are incorporated herein by reference in reliance upon such
report given on the authority of such firm as experts in accounting and
auditing.

      With respect to the unaudited condensed consolidated interim financial
information for the three-month periods ended March 31, 1999 and March 31, 1998,
the six-month periods ended June 30, 1999 and June 30, 1998, and the nine-month
periods ended September 30, 1999 and September 30, 1998, incorporated by
reference in this Prospectus, Ernst & Young LLP have reported that they have
applied limited procedures in accordance with professional standards for a
review of such information. However, their separate report, included in State
Street Corporation's Quarterly Reports on Form 10-Q for the quarters ended March
31, 1999, June 30, 1999, and September 30 1999, and incorporated herein by
reference, states that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on their
report on such information should be restricted considering the limited nature
of the review procedures applied. The independent auditors are not subject to
the liability provisions of Section 11 of the Securities Act of 1933 (the "Act")
for their report on the unaudited interim financial information because that
report is not a "report" or a "part" of the Registration Statement prepared or
certified by the auditors within the meaning of Sections 7 and 11 of the Act.

ITEM 15. Indemnification of Directors and Officers.

      Section 67 of Chapter 156B of the General Laws of Massachusetts provides
that to the extent specified in or authorized by:

      o     the articles of organization;

      o     a by-law adopted by shareholders; or

      o     a vote adopted by the holders of the majority of shares of stock
            entitled to vote on the election of directors,

a corporation can indemnify directors, officers, employees and other agents of
the corporation (and persons who serve at its request as directors, officers,
employees and other agents of another organization or who serve at its request
in any capacity with respect to any employee benefit plan). This indemnification
does not apply to any matter as to which such person shall have been adjudicated
in any proceeding not to have acted in good faith in the reasonable belief that
the action was in the best interest of the corporation.

      The Articles of Organization of State Street (Article 6) provide the
following:

            The corporation shall to the fullest extent legally permissible
      indemnify each person who is or was a director, employee or other agent of
      the corporation and each person who is or was serving at the request of
      the corporation as a director, trustee, officer, employee or other agent
      of another corporation or of any partnership, joint venture, trust,
      employee benefit plan or other enterprise or organization against all
      liabilities, costs and expenses, including but not limited to amounts paid
      in satisfaction of judgments, in settlement or as fines and penalties, and
      counsel fees and disbursements, reasonably incurred by him in connection
      with the defense or disposition of or otherwise in connection with or
      resulting from any action, suit or other proceeding, whether civil,
      criminal, administrative or investigative, before any court or
      administrative or legislative or investigative body, in which he may be or
      may have been involved as a party or otherwise or with which he may be or
      may have been threatened, while in office or thereafter, by reason of his
      being or having been such a director, officer, employee, agent or trustee,
      or by reason of any action taken or not taken in any such capacity, except
      with respect to any matter as to which he shall have been finally
      adjudicated by a court of competent jurisdiction not


      to have acted in good faith in the reasonable belief that his action was
      in the best interests of the corporation (any person serving another
      organization in one or more of the indicated capacities at the request of
      the corporation who shall not have been adjudicated in any proceeding not
      to have acted in good faith in the reasonable belief that his action was
      in the best interest of such other organization shall be deemed so to have
      acted in good faith with respect to the corporation) or to the extent that
      such matter relates to service with respect to an employee benefit plan,
      in the best interest of the participants or beneficiaries of such employee
      benefit plan. Expenses, including but not limited to counsel fees and
      disbursements, so incurred by any such person in defending any such
      action, suit or proceeding, shall be paid from time to time by the
      corporation in advance of the final disposition of such action, suit or
      proceeding upon receipt of an undertaking by or on behalf of the person
      indemnified to repay the amounts so paid if it shall ultimately be
      determined that indemnification of such expenses is not authorized
      hereunder.

            If, in an action, suit or proceeding brought by or in the name of
      the corporation, a director of the corporation is held not liable for
      monetary damages, whether because that director is relieved of personal
      liability under the provisions of this Article Six of the Articles of
      Organization, or otherwise, that director shall be deemed to have met the
      standard of conduct set forth above and to be entitled to indemnification
      for expenses reasonably incurred in the defense of such action, suit or
      proceeding.

            As to any matter disposed of by settlement by any such person,
      pursuant to a consent decree or otherwise, no such indemnification either
      for the amount of such settlement or for any other expenses shall be
      provided unless such settlement shall be approved as in the best interests
      of the corporation, after notice that it involves such indemnification,
      (a) by vote of a majority of the disinterested directors then in office
      (even though the disinterested directors be less than a quorum), or (b) by
      any disinterested person or persons to whom the question may be referred
      by vote of a majority of such disinterested directors, or (c) by vote of
      the holders of a majority of the outstanding stock at the time entitled to
      vote for directors, voting as a single class, exclusive of any stock owned
      by any interested person, or (d) by any disinterested person or persons to
      whom the question may be referred by vote of the holders of a majority of
      such stock. No such approval shall prevent the recovery from any such
      director, officer, employee, agent or trustee of any amounts paid to him
      or on his behalf as indemnification in accordance with the preceding
      sentence if such person is subsequently adjudicated by a court of
      competent jurisdiction not to have acted in good faith in the reasonable
      belief that his action was in the best interests of the corporation.

            The right of indemnification hereby provided shall not be exclusive
      of or affect any other rights to which any director, officer, employee,
      agent or trustee may be entitled or which may lawfully be granted to him.
      As used herein, the terms "director," "officer," "employee," "agent" and
      "trustee" include their respective executors, administrators and other
      legal representatives, an "interested" person is one against whom the
      action, suit or other proceeding in question or another action, suit or
      other proceeding on the same or similar grounds is then or had been
      pending or threatened, and a "disinterested" person is a person against
      whom no such action, suit or other proceeding is then or had been pending
      or threatened.

            By action of the board of directors, notwithstanding any interest of
      the directors in such action, the corporation may purchase and maintain
      insurance, in such amounts as the board of directors may from time to time
      deem appropriate, on behalf of any person who is or was a director,
      officer, trustee, employee or other agent of the corporation, or is or was
      serving at the requests of the corporation as a director, officer,
      trustee, employee or other agent of another corporation or of any
      partnership, joint venture, trust, employee benefit plan or other
      enterprise or organization against any liability incurred by him in any
      such capacity, or arising out of his status as such, whether or not the
      corporation would have the power to indemnify him against such liability.

            A director of this corporation shall not be personally liable to the
      corporation or its stockholders for monetary damages for breach of
      fiduciary duty as a director notwithstanding any provision of law imposing
      such liability, provided, however, that this paragraph of Article Six
      shall not eliminate the liability of a director to the extent such
      liability is imposed by applicable law (i) for any breach of the
      director's duty of loyalty to this


                                      -46-


      corporation or its stockholders, (ii) for acts or omissions not in good
      faith or which involve intentional misconduct or a knowing violation of
      law, (iii) for any transaction from which the director derived an improper
      personal benefit, or (iv) for paying a dividend, approving a stock
      repurchase or making loans which are illegal under certain provisions of
      Massachusetts law, as the same exists or hereafter may be amended. If
      Massachusetts law is hereafter amended to authorize the further limitation
      of the legal liability of the directors of this corporation, the liability
      of the directors shall then be deemed to be limited to the fullest extent
      then permitted by Massachusetts law as so amended. Any repeal or
      modification of this paragraph of this Article Six which may hereafter be
      effected by the stockholders of this corporation shall be prospective
      only, and shall not adversely affect any limitation on the liability of a
      director for acts or omissions prior to such repeal or modification.

      In addition, State Street maintains a directors' and officers' liability
insurance policy.

      Under the trust agreement of each issuer trust, State Street will agree to
indemnify the issuer trustee of each issuer trust, and to hold the issuer
trustees harmless against, any loss, damage, claims, liability or expense
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the applicable trust
agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties under such trust agreement.

ITEM 17.  Undertakings

      Each of the undersigned Registrants hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, as amended:

o     each filing of a Registrant's annual report pursuant to Section 13(a) or
      Section 15(d) of the Securities Exchange Act of 1934 that is incorporated
      by reference in this Registration Statement shall be deemed to be a new
      registration statement relating to the securities offered herein; and

o     the offering of such securities at that time shall be deemed to be the
      initial bona fide offering thereof.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
each Registrant pursuant to the provisions described under Item 15 above, or
otherwise, each Registrant has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by each Registrant of expenses incurred
or paid by a director, officer or controlling person of each Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, each Registrant will, unless in the opinion of its counsel the
matter has been settled by the controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

      Each of the undersigned Registrants hereby also undertakes:

      (1)   To file, during any period in which offers or sales are being made,
            a post-effective amendment to this Registration Statement:

            (i)   To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;


                                      -50-


            (ii)  To reflect in the prospectus any facts or events arising after
                  the effective date of this Registration Statement (or the most
                  recent post-effective amendment thereto) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in this Registration Statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in volume and price
                  represent no more than a 20% change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective registration statement; and

            (iii) To include any material information with respect to the plan
                  of distribution not previously disclosed in this Registration
                  Statement or any material change to such information in this
                  Registration Statement; provided, however, that paragraphs
                  (1)(i) and 1(ii) do not apply if the information required to
                  be included in a post- effective amendment by those paragraphs
                  is contained in periodic reports filed by a Registrant
                  pursuant to Section 13 or Section 15(d) of the Securities
                  Exchange Act of 1934 that are incorporated by reference in
                  this Registration Statement.

      (2)   That, for the purpose of determining any liability under the
            Securities Act of 1933, each such post-effective amendment shall be
            deemed to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof.

      (3)   To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.

      (4)   To provide to the underwriter at the closing specified in the
            underwriting agreement certificates in such denominations and
            registered in such names as required by the underwriter to permit
            prompt delivery to each purchaser.

      (5)   That, for the purposes of determining any liability under the
            Securities Act of 1933:

            (i)   The information omitted from the form of prospectus filed as
                  part of this Registration Statement in reliance upon Rule 430A
                  and contained in the form of prospectus filed by the
                  Registrants pursuant to Rule 424(b)(1) or (4) or 497(h) under
                  the Securities Act shall be deemed to be part of this
                  Registration Statement as of the time it was declared
                  effective.

            (ii)  Each post-effective amendment that contains a form of
                  prospectus shall be deemed to be a new Registration Statement
                  relating to the securities offered therein, and the offering
                  of such securities at that time shall be deemed to be the
                  initial bona fide offering thereof.
