                  The Capital Units will consist of Debentures, Guarantees and
Purchase Contracts and will be issued in the form of Book-Entry Capital Units in
accordance with the terms of Article Eleven hereof, unless a Holder requests
that Capital Units be issued to or upon the order of such Holder in the form of
Definitive Capital Units represented by one or more Capital Unit Certificates,
either upon the original issuance thereof or pursuant to Section 311, and except
as otherwise set forth in Section 311.

                  The definitive Capital Unit Certificates shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined with respect to the portion of the Capital Unit
Certificates evidencing the Debentures by the officers of MS plc executing such
Debentures and with respect to the portion of the Capital Unit Certificates
evidencing the Purchase Contracts by the officers of the Corporation executing
the Purchase Contracts, consistent with the provisions of this Agreement, as
evidenced by their execution thereof.

Section 202.      Form of Certificate of Authentication and Countersignature.

                  The form of the Trustee's certificate of authentication of the
Debentures, and the form of the Agent's countersignature of the Purchase
Contracts, each constituting a part of the Capital Units evidenced by the
Capital Unit Certificates, shall be in substantially the form set forth on the
applicable form of the Capital Unit Certificates.

                                  ARTICLE THREE

                                The Capital Units

Section 301.      Denominations.

                  Capital Units shall be issuable only in denominations of a
single Capital Unit and any integral multiple thereof.

Section 302.      Rights and Obligations Evidenced by the Capital Units.

                  Capital Units shall evidence the ownership by the Holder
thereof of the principal amount of the number of Debentures specified on the
face of a Capital Unit Certificate representing Definitive Capital Units or in
Schedule A attached to the Global Debenture relating to Book-Entry Capital
Units, the benefits of the Guarantee with respect to such Debentures and the
rights and obligations of the Corporation and the Holder under the number of
Purchase Contracts specified on the face of a Capital Unit Certificate
representing Definitive Capital Units or in Schedule I attached to the Global
Purchase Contract relating to Book-Entry Capital Units. Prior to the purchase,
if any, of Depositary Shares under the Purchase Contracts, the Capital Units
shall not entitle the Holders to any of the rights of a holder of Depositary
Shares, Preferred Stock or any other shares of capital stock of the Corporation,
including, without limitation, the right to vote or receive any


<PAGE>

                                       12

dividends or other payments or to consent or to receive notice as shareholders
with respect to the meetings of shareholders or for the election of directors of
the Corporation or for any other matter, or any other rights whatsoever as
shareholders of the Corporation, except to the extent expressly provided in
Article Four. The rights and obligations of MS plc, the Corporation and the
Holders with respect to the Debentures and the Guarantee are specified under the
Indenture.

Section 303.      Execution, Authentication, Delivery and Dating.

                  Upon the execution and delivery of this Agreement, and at any
time and from time to time thereafter, MS plc and the Corporation may deliver,
subject to any limitation on the aggregate principal amount of Debentures
represented thereby, an unlimited number of Capital Unit Certificates executed
by MS plc (with respect to the Debentures constituting a part of the Capital
Units evidenced thereby) and the Corporation (with respect to the Purchase
Contracts constituting a part of the Capital Units evidenced thereby) to the
Trustee and the Agent for authentication, countersignature and execution, as the
case may be, together with their respective Issuer Orders for authentication,
countersignature and execution of such Capital Unit Certificates, and the
Trustee in accordance with the Indenture and the Issuer Order of MS plc shall
authenticate the Debentures constituting a part of the Capital Units evidenced
by such Capital Unit Certificates, and the Agent in accordance with this
Agreement and the Issuer Order of the Corporation shall countersign and execute
on behalf of the Holder the Purchase Contracts forming a part of the Capital
Units evidenced by such Capital Unit Certificates, and deliver such Capital Unit
Certificates upon the order of MS plc and the Corporation.

                  The Debentures constituting a part of the Capital Units shall
be executed on behalf of MS plc and shall be authenticated by the Trustee in
accordance with the terms of the Indenture. The Purchase Contracts constituting
a part of the Capital Units shall be executed on behalf of the Corporation in
accordance with Section 401.

Section 304.      Temporary Capital Unit Certificates.

                  Pending the preparation of definitive Capital Unit
Certificates, MS plc (with respect to the Debentures constituting a part of the
Capital Units evidenced thereby) and the Corporation (with respect to the
Purchase Contracts constituting a part of the Capital Units evidenced thereby)
shall execute and deliver to the Trustee and the Agent, and the Trustee and the
Agent shall authenticate, countersign, execute on behalf of the Holder and
deliver, as appropriate, in lieu of such definitive Capital Unit Certificates,
temporary Capital Unit Certificates that are in substantially the form set forth
in Exhibit A hereto, with such letters, numbers or other marks of identification
or designation and such legends or endorsements printed, lithographed or
engraved thereon as may be required by the rules of any securities exchange on
which the Capital Units are listed or as may, consistent herewith, be determined
with respect to the portion of the Capital Unit Certificates evidencing the
Debentures by the officers of MS plc executing such Debentures and with respect
to the

<PAGE>

                                       13

portion of the Capital Unit Certificates evidencing the Purchase Contracts by
the officers of the Corporation executing the Purchase Contracts, in each case
as evidenced by their execution of the Debentures and Purchase Contracts
evidenced by such Capital Unit Certificates.

                  If temporary Capital Unit Certificates are issued, MS plc and
the Corporation will cause definitive Capital Unit Certificates to be prepared
without unreasonable delay. After the preparation of definitive Capital Unit
Certificates, the temporary Capital Unit Certificates shall be exchangeable for
definitive Capital Unit Certificates upon surrender of the temporary Capital
Unit Certificates at the Corporate Trust Office, at the expense of MS plc and
the Corporation and without charge to any Holder. Upon surrender for
cancellation of any one or more temporary Capital Unit Certificates, MS plc
(with respect to the Debentures constituting a part of the Capital Units
evidenced thereby) and the Corporation (with respect to the Purchase Contracts
constituting a part of the Capital Units evidenced thereby) shall execute and
deliver to the Trustee and the Agent, and the Trustee and the Agent shall
authenticate, countersign, execute on behalf of the Holder and deliver, as
appropriate, in exchange therefor definitive Capital Unit Certificates of like
tenor of authorized denominations and evidencing a like number of Capital Units
as the temporary Capital Unit Certificate or Certificates so surrendered. Until
so exchanged, the temporary Capital Unit Certificates shall in all respects
evidence the same benefits and the same obligations under the Debentures, the
Guarantee, the Purchase Contracts, the Indenture and this Agreement as
definitive Capital Unit Certificates.

Section 305.      Registration of Transfer and Exchange.

                  The Agent shall keep at its Corporate Trust Office a register
(the register maintained in such office being herein referred to as the
"Purchase Contract Register") in which, subject to such reasonable regulations
as it may prescribe, the Agent shall provide for the registration of Purchase
Contracts and of transfers of Purchase Contracts (the Agent, in such capacity,
the "Purchase Contract Registrar").

                  Upon surrender for registration of transfer of any Capital
Unit Certificate at the Corporate Trust Offices of the Trustee and the Agent, MS
plc (with respect to the Debentures constituting a part of the Definitive
Capital Units evidenced thereby) and the Corporation (with respect to the
Purchase Contracts constituting a part of the Definitive Capital Units evidenced
thereby) shall execute and deliver to the Trustee and the Agent, and the Trustee
and the Agent shall authenticate, countersign, execute on behalf of the
designated transferee or transferees and deliver, as appropriate, in the name of
the designated transferee or transferees, one or more new Capital Unit
Certificates of any authorized denominations, of like tenor, and evidencing a
like number of Definitive Capital Units.

                  At the option of the Holder or as otherwise set forth in
Section 311, (a) Definitive Capital Units may be transferred or exchanged for
Definitive Capital Units of any


<PAGE>

                                       14

authorized denominations and for interests in Book-Entry Capital Units and (b)
interests in Book-Entry Capital Units may be transferred or exchanged for
Definitive Capital Units of any authorized denominations, in each case
evidencing the number of Capital Units transferred or exchanged, upon surrender
of the Capital Unit Certificates to be so transferred or exchanged at the
Corporate Trust Office of the Agent or upon receipt by the Book-Entry Unit
Depositary of written instructions from the Depositary. Whenever any Capital
Unit Certificates are so surrendered for transfer or exchange or any request is
so received in accordance with Section 1104 to exchange Definitive Capital Units
and Book-Entry Capital Units, MS plc (with respect to the Debentures
constituting a part of the Definitive Capital Units evidenced thereby) and the
Corporation (with respect to the Purchase Contracts constituting a part of the
Definitive Capital Units evidenced thereby) shall execute and deliver to the
Trustee and the Agent, and the Trustee and the Agent shall authenticate,
countersign, execute on behalf of the Holder and deliver, as appropriate, the
Capital Unit Certificates that the Holders making the exchange or the
transferees are entitled to receive. Whenever Book-Entry Capital Units are
exchanged for Definitive Capital Units or whenever Definitive Capital Units are
exchanged for Book-Entry Capital Units, the Book-Entry Unit Depositary shall
cause (i) Schedule A of the Global Debenture to be endorsed to reflect any
increase or decrease, as the case may be, in the principal amount of Debentures
that comprise Book-Entry Capital Units evidenced thereby as a result of such
exchange, and (ii) Schedule I of the Global Purchase Contract to be endorsed to
reflect any increase or decrease, as the case may be, in the number of Purchase
Contracts that comprise Book-Entry Capital Units evidenced thereby as a result
of such exchange, whereupon such number of Book-Entry Capital Units shall be
decreased or increased for all purposes by the number so exchanged, as noted.

                  All Capital Unit Certificates authenticated, countersigned and
executed upon any registration of transfer or exchange of a Capital Unit
Certificate shall evidence the ownership of the principal amount of the number
of Debentures specified on the face thereof, the benefits of the Guarantee with
respect to such Debentures and the rights and obligations of the Holder and the
Corporation under the number of Purchase Contracts specified on the face thereof
and shall be entitled to the same benefits, and be subject to the same
obligations, under the Indenture and this Agreement as the Definitive Capital
Units evidenced by the Capital Unit Certificate surrendered upon such
registration of transfer or exchange.

                  Every Capital Unit Certificate presented or surrendered for
registration of transfer or for exchange shall (if so required by MS plc, the
Corporation or the Agent) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to MS plc, the Corporation and the
Agent, duly executed by the Holder thereof or his attorney duly authorized in
writing.

                  No service charge shall be made for any transfer or exchange
of a Capital Unit, but MS plc, the Corporation and the Agent may require payment
from the Holder of a sum sufficient to cover any tax or other governmental
charge that may be imposed in


<PAGE>

                                       15

connection with any registration of transfer or exchange of Capital Units, other
than any exchanges pursuant to Section 306 not involving any transfer.

                  Notwithstanding the foregoing, and subject to Section 2.8 of
the Indenture, MS plc (with respect to the Debentures constituting a part of the
Capital Units evidenced thereby) and the Corporation (with respect to the
Purchase Contracts constituting a part of the Capital Units evidenced thereby)
shall not be obligated to execute and deliver to the Trustee or the Agent, and
neither the Trustee, under the terms of the Indenture, nor the Agent shall be
obligated to authenticate, countersign and execute on behalf of the Holder any
Capital Unit Certificate presented or surrendered for registration of transfer
or for exchange of the Debentures and Purchase Contracts evidenced thereby or
any Capital Unit Certificate to be issued in exchange for interests in
Book-Entry Capital Units or to reflect any increase or decrease in a Global
Debenture or Global Purchase Contract (i) during the period beginning any time
on or after the opening of business 15 days before the day of mailing of a
notice of redemption or acceleration of Purchase Contracts and ending at the
close of business on the day of the giving of such notice, (ii) that evidences
or would evidence Purchase Contracts selected or called for redemption or
acceleration or (iii) at any given date, if such date is on or after any date
that is after the Purchase Date or the date of redemption, as applicable, with
respect to the Purchase Contracts evidenced or to be evidenced by such Capital
Unit Certificate, except with respect to any Debentures that remain or will
remain Outstanding following such Purchase Date or date of redemption.

Section 306.      Mutilated, Destroyed, Lost and Stolen Capital Unit 
                  Certificates.

                  If any mutilated Capital Unit Certificate is surrendered to
the Agent, MS plc (with respect to the Debentures constituting a part of the
Capital Units evidenced thereby) and the Corporation (with respect to the
Purchase Contracts constituting a part of the Capital Units evidenced thereby)
shall execute and deliver to the Trustee and the Agent, and the Trustee and the
Agent shall authenticate, countersign, execute on behalf of the Holder and
deliver, as appropriate, in exchange therefor a new Capital Unit Certificate of
like tenor, evidencing the same number of Capital Units and bearing a number not
contemporaneously outstanding.

                  If there shall be delivered to MS plc, the Corporation, the
Trustee and the Agent (i) evidence to their satisfaction of the destruction,
loss or theft of any Capital Unit Certificate and (ii) such security or
indemnity as may be required by them to hold each of them and any agent of any
of them harmless, then, in the absence of notice to MS plc, the Corporation, the
Trustee or the Agent that such Capital Unit Certificate has been acquired by a
bona fide purchaser, MS plc (with respect to the Debentures constituting a part
of the Capital Units evidenced thereby) and the Corporation (with respect to the
Purchase Contracts constituting a part of the Capital Units evidenced thereby)
shall execute and deliver to the Trustee and the Agent, and the Trustee (in
accordance with the provisions of the Indenture) and the Agent shall
authenticate, countersign, execute on behalf of the Holder and deliver to the
Holder, as appropriate, in lieu of any such destroyed, lost or stolen


<PAGE>

                                       16

Capital Unit Certificate, a new Capital Unit Certificate of like tenor,
evidencing the same number of Capital Units and bearing a number not
contemporaneously outstanding.

                  Notwithstanding the foregoing, MS plc (with respect to the
Debentures constituting a part of the Capital Units evidenced thereby) and the
Corporation (with respect to the Purchase Contracts constituting a part of the
Capital Units evidenced thereby) shall not be obligated to execute and deliver
to the Trustee or the Agent, and neither the Trustee, under the Indenture, nor
the Agent shall be obligated to authenticate, countersign and execute on behalf
of the Holder, or deliver to the Holder, a new Capital Unit Certificate (i)
during the period beginning any time on or after the opening of business 15 days
before the day of mailing of a notice of redemption or acceleration of the
Purchase Contracts evidenced by such Capital Unit Certificate and ending at the
close of business on the day of the giving of such notice, (ii) that evidences
Purchase Contracts selected or called for redemption or acceleration or (iii) at
any given date, if such date is on or after the Purchase Date or date of
redemption, as applicable, with respect to the Purchase Contracts evidenced by
such Capital Unit Certificate, except with respect to any Registered Definitive
Debentures that remain or will remain Outstanding following such Purchase Date
or date of redemption. In lieu of delivery of a new Capital Unit Certificate,
upon satisfaction of the applicable conditions specified in clauses (i) and (ii)
of the preceding paragraph, the Agent shall deliver or cause to be delivered on
the applicable Purchase Date or redemption date (i) in respect of Purchase
Contracts constituting a part of the Capital Units evidenced by such Capital
Unit Certificate that are selected or called for redemption, the redemption
price of such Purchase Contracts or (ii) in respect of Purchase Contracts
constituting a part of the Capital Units evidenced by such Capital Unit
Certificate with respect to which a Cash Settlement or Debenture Settlement has
taken place, (x) the Depositary Shares issuable with respect to such Purchase
Contracts (and, in the case of an effective Cash Settlement, the related
Registered Definitive Debentures) or (y) if a Termination Event shall have
occurred or a Purchase Contract Default has occurred by virtue of the
Corporation's having failed to issue the Preferred Stock against tender by the
Agent of payment for the Depositary Shares evidencing such Preferred Stock, the
payment, if any, received by the Agent from the Holder in respect of the
Purchase Price of such Purchase Contracts or in respect of principal with
respect to the related Debentures received by the Agent, as the case may be, in
each case as provided in Section 405, Section 903 and Article Ten, as
applicable.

                  Upon the issuance of any new Capital Unit Certificate under
this Section, MS plc, the Corporation and the Agent may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Agent) connected therewith.

                  Every new Capital Unit Certificate executed pursuant to this
Section in lieu of any destroyed, lost or stolen Capital Unit Certificate shall
constitute an original additional contractual obligation of MS plc (with respect
to the Debentures constituting a part of the Capital Units evidenced thereby)
and the Corporation (with respect to the Guarantee and the Purchase Contracts
constituting a part of the Capital Units evidenced thereby) and of the


<PAGE>

                                       17

Holder (with respect to the Purchase Contracts constituting a part of the
Capital Units evidenced thereby), whether or not the destroyed, lost or stolen
Capital Unit Certificate (and the Debentures, the Guarantee and the Purchase
Contracts evidenced thereby) shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Agreement equally and
proportionately with any and all other Capital Unit Certificates delivered
hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Capital Unit
Certificates.

 Section 307.     Persons Deemed Owners.

                  Prior to due presentment of a Capital Unit Certificate for
registration of transfer, MS plc, the Corporation, the Trustee and the Agent,
and any agent of MS plc, the Corporation, the Trustee or the Agent, may treat
the Person in whose name the Debentures and Purchase Contracts evidenced by such
Capital Unit Certificate are registered and, with respect to the Book-Entry
Capital Units, the Book-Entry Unit Depositary, as the owner of the Capital Units
evidenced thereby, for the purpose of receiving payments on the Debentures
constituting a part of the Capital Units evidenced thereby, payment of any
redemption price on the Debentures or Purchase Contracts constituting a part of
the Capital Units evidenced thereby, performance of the Purchase Contracts
constituting a part of the Capital Units evidenced thereby and for all other
purposes whatsoever, whether or not payment with respect to such Debentures or
Purchase Contracts shall be overdue and notwithstanding any notice to the
contrary, and none of MS plc, the Corporation, the Trustee, the Agent nor any
agent of MS plc, the Corporation, the Trustee or the Agent shall be affected by
notice to the contrary. Notwithstanding the foregoing, the Book-Entry Unit
Depositary shall not be personally liable for any failure to perform a Purchase
Contract.

Section 308.      Cancellation.

                  All Capital Unit Certificates surrendered for payment, and all
Capital Unit Certificates surrendered for redemption or termination of the
Debentures or the Purchase Contracts evidenced thereby, delivery of Depositary
Shares or registration of transfer or exchange shall, if surrendered to any
Person other than the Trustee or the Agent, be delivered to the Trustee or the
Agent, as appropriate, and, if not already cancelled, the Debentures and
Purchase Contracts evidenced by such Capital Units shall be promptly cancelled
by the Trustee or the Agent, as appropriate; provided, however, that a Holder or
any transferee shall be entitled to receive (i) a certificate evidencing the
ownership of a Registered Definitive Debenture or (ii) an interest in a Global
Debenture, in each case relating to a Closed Purchase Contract for which a Cash
Settlement has been effected. MS plc or the Corporation may at any time deliver
to the Trustee or the Agent for cancellation any Capital Unit Certificates
previously authenticated, countersigned, executed and delivered hereunder and
under the Indenture which MS plc or the Corporation may have acquired in


<PAGE>

                                       18

any manner whatsoever, and all Capital Unit Certificates so delivered shall,
upon Issuer Order of each of MS plc and the Corporation, be promptly cancelled
by the Trustee and the Agent. No Capital Unit Certificates shall be
authenticated, countersigned and executed in lieu of or in exchange for any
Capital Unit Certificates cancelled as provided in this section, except as
permitted by this Agreement. All cancelled Capital Unit Certificates held by the
Agent shall be disposed of in accordance with its customary procedures and a
certificate of their disposition shall be delivered by the Agent to MS plc and
the Corporation, unless by Issuer Order either MS plc or the Corporation shall
direct that cancelled Capital Unit Certificates be returned to it.

                  If MS plc, the Corporation or any Affiliate of MS plc or the
Corporation shall acquire any Capital Unit Certificate, such acquisition shall
not operate as a cancellation of such Capital Unit Certificate unless and until
such Capital Unit Certificate is delivered to the Trustee or the Agent cancelled
or for cancellation.

Section 309.      Capital Units Not Separable.

                  Notwithstanding anything to the contrary contained herein, in
the Indenture, the Debentures, the Guarantees or the Purchase Contracts
constituting the Capital Units, the Capital Units shall not be separable into
their constituent parts, and the rights and obligations of the Holders with
respect to the Debentures, the Guarantees and the Purchase Contracts may be
acquired, and may be transferred and exchanged, only as Capital Units, and no
Holder, or any transferee thereof, shall be entitled to receive a certificate
evidencing the ownership of a Debenture, the benefits of the Guarantee or the
rights and obligations of the Holder and the Corporation under a Purchase
Contract, unless such Debenture, Guarantee and Purchase Contract are evidenced
by a Capital Unit Certificate, as provided in this Agreement; provided, however,
that a Holder or any transferee thereof shall be entitled to receive (i) a
certificate evidencing the ownership of a Registered Definitive Debenture or
(ii) an interest in a Global Debenture, in each case relating to a Closed
Purchase Contract for which a Cash Settlement has been effected.

Section 310.      Book-Entry Capital Units.

                  Book-Entry Capital Units shall only be issued by the
Book-Entry Unit Depositary as certificateless depositary interests in accordance
with Section 1101.

Section 311.      Exchange of Book-Entry Capital Units and Definitive Capital 
                  Units.

                  Holders of Book-Entry Capital Units shall receive Definitive
Capital Units in exchange for interests in Book-Entry Capital Units if DTC
notifies MS plc and the Corporation that it is unwilling or unable to continue
as Depositary with respect to the certificateless depositary interests
representing Book-Entry Capital Units or if at any time it ceases to be a
clearing agency under the Securities Exchange Act of 1934, as amended (the


<PAGE>

                                       19

"Exchange Act"), and a successor Depositary registered as a clearing agency
under the Exchange Act is not appointed by MS plc and the Corporation within 90
days.

                  Definitive Capital Units shall be authenticated, countersigned
and executed in exchange for interests in Book-Entry Capital Units if (i) the
Book-Entry Unit Depositary notifies MS plc, the Corporation and the Agent that
it is unwilling or unable to continue as Book-Entry Unit Depositary, and no
successor Book-Entry Unit Depositary is appointed within 90 days, (ii) an Event
of Default with respect to the Debentures occurs or (iii) at any time MS plc and
the Corporation, in their sole discretion, determine that Capital Units shall
not be represented by Book-Entry Capital Units.

                  Interests in Book-Entry Capital Units may also be transferred
or exchanged for Definitive Capital Units upon the request of the Holder of the
Book-Entry Capital Units if the Book-Entry Unit Depositary on behalf of, and
based on the instructions of, the Depositary requests the Trustee and the Agent
to authenticate, countersign and execute, as the case may be, Capital Unit
Certificates representing Definitive Capital Units (such request being referred
to herein as an "Optional Definitive Capital Unit Request").

                  Definitive Capital Units exchanged for interests in Book-Entry
Capital Units shall be denominated in the amounts and registered in the name of
such Person or Persons as the Book-Entry Unit Depositary, on behalf of, and
based on the instructions of, the Depositary, shall instruct the Agent and the
Trustee.

                  Holders of Definitive Capital Units may transfer or exchange
such Definitive Capital Units for interests in Book-Entry Capital Units by
depositing the Capital Unit Certificates evidencing such Definitive Capital
Units with the Agent and requesting the Agent and the Trustee to effect such
exchange. The Book-Entry Unit Depositary and the Agent shall notify the
Depositary of any such exchange and, upon delivery to the Agent and the Trustee
of the Capital Unit Certificates evidencing the Definitive Capital Units to be
so transferred or exchanged, the Book-Entry Unit Depositary shall take all
actions required in accordance with Section 1104 with respect to the Global
Debenture and the Global Purchase Contract evidencing such Book-Entry Capital
Units and Capital Unit Certificates evidencing the remaining Definitive Capital
Units, if any, will be issued in accordance with Section 305.

Section 312.      Additional Amounts.

                  Neither MS plc nor the Corporation shall be obligated to pay
any Additional Amounts with respect to the Debentures constituting a part of
Definitive Capital Units that are delivered pursuant to (i) an Optional
Definitive Capital Unit Request or (ii) the request of a Holder upon the
original delivery of such Capital Units.

                             The Purchase Contracts

Section 401.      Execution and Delivery of Purchase Contracts.

                  Purchase Contracts, whenever issued by the Corporation, may be
issued in definitive or global registered form, shall be dated the date of
countersignature and execution thereof by the Agent and (a) if a Purchase
Contract forms part of a Definitive Capital Unit, shall be printed on the form
of the Capital Unit Certificate evidencing such Definitive Capital Unit or (b)
if a Purchase Contract forms part of a Book-Entry Capital Unit, shall be
represented by a Global Purchase Contract relating to such Book-Entry Capital
Unit in the form set forth in Exhibit A hereto. The Purchase Contracts shall be
executed on behalf of the Corporation by the Chairman or Vice Chairman of its
Board of Directors, its President, General Counsel, Chief Financial Officer,
Treasurer, Secretary, Assistant Secretary or any Managing Director, and may, but
need not, be attested. The signatures of any of these officers may be manual or
facsimile.

                  No Purchase Contract shall be valid until it has been
countersigned by the manual signature of the Agent and executed on behalf of the
Holder by the manual or facsimile signature of the Agent. Such countersignature
by the Agent upon, and execution by the Agent of, any Purchase Contract executed
by the Corporation shall be conclusive evidence, and the only evidence, that the
Purchase Contract so countersigned and executed has been duly issued and
delivered hereunder.

                  In case any officer of the Corporation who shall have signed
any of the Purchase Contracts either manually or by facsimile signature shall
cease to be such officer before any Purchase Contract so signed shall have been
countersigned, executed on behalf of the Holder and delivered by the Agent or,
if applicable, before the Debenture that is part of the same Capital Unit shall
have been authenticated by the Trustee, such Purchase Contracts nevertheless may
be countersigned and delivered as though the person who signed such Purchase
Contracts had not ceased to be such officer of the Corporation; and any Purchase
Contract may be signed on behalf of the Corporation by such persons as, at the
actual date of the execution thereof, shall be the proper officers of the
Corporation, although at the date of the execution of this Agreement any such
person was not such an officer.

Section 402.      Further Provisions Relating to Issuance of Purchase Contracts.

                  Purchase Contracts relating to the purchase of an aggregate of
not more than 134,000 Depositary Shares, may be executed by the Corporation and
delivered to the Agent upon the execution of this Agreement or from time to time
thereafter in connection with exchanges, substitutions and transfers of Capital
Units. Prior to the original issuance of the

<PAGE>

                                       21

Purchase Contracts, the Agent shall have received an Issuer Order of the
Corporation directing the countersignature, execution on behalf of the Holder
and delivery thereof to or upon the order of the Corporation of the Purchase
Contracts to be evidenced by Capital Unit Certificates to be registered in the
names of the Holders (with respect to Definitive Capital Units) and a Global
Purchase Contract registered in the name of the Book-Entry Unit Depositary (with
respect to Book-Entry Capital Units). Subsequent to such original issuance of
the Purchase Contracts, the Agent shall, subject to the conditions set forth in
this Article and Article Three, countersign and execute on behalf of the Holder
Purchase Contracts issued in exchange or substitution for or upon transfer of
Capital Unit Certificates evidencing one or more previously countersigned and
executed Unsettled Purchase Contracts evidenced by the Capital Unit Certificates
to be exchanged, substituted for or transferred.

Section 403.      Purchase of Depositary Shares; Acceleration of Purchase 
                  Obligations.

                  (a) Each Unsettled Purchase Contract shall obligate the Holder
of the related Capital Unit to purchase, and the Corporation to sell, on the
Stated Purchase Date, one Depositary Share, at a price of $1,000.00 per
Depositary Share (the "Purchase Price"), unless a Termination Event shall have
occurred.

                  (b) Subject to paragraph (c) of this Section, the Corporation
may, at its sole option and in its sole discretion, at any time or from time to
time on not less than 30 nor more than 60 days' written notice (an "Acceleration
Notice") to the Agent and the Holders, in the manner provided in Section 1305
and Section 1306, accelerate the obligations of the Holders of at least 50,000
Unsettled Purchase Contracts to purchase, and of the Corporation to sell, on the
next succeeding Interest Payment Date (provided that such Interest Payment Date
may not be prior to February 28, 1998), one Depositary Share per Unsettled
Purchase Contract subject to such acceleration; provided that no such
acceleration with respect to fewer than all Unsettled Purchase Contracts shall
result in fewer than 50,000 Unsettled Purchase Contracts remaining Outstanding
after such Purchase Date; and provided further that the Corporation shall have
the right, in its sole discretion, on or before the 10th day prior to such
Interest Payment Date, to rescind any Acceleration Notice by written notice to
the Agent and the Holders (whereupon all rights and obligations of the
Corporation and the Holders that would have arisen as a result of such
Acceleration Notice shall be of no force and effect), without prejudice to the
rights of the Corporation, including without limitation its rights to deliver an
Acceleration Notice in the future. If fewer than all Unsettled Purchase
Contracts are to be accelerated to a particular Accelerated Purchase Date, the
Agent shall select from among the Unsettled Purchase Contracts such number
thereof as are being accelerated on a pro rata basis, with appropriate
adjustment being made to prevent the fractional acceleration of Purchase
Contracts, such that Purchase Contracts are accelerated only in whole and not in
part.


<PAGE>

                                       22


                  (c) No Accelerated Purchase Date may occur if a Cancellation
Event has occurred with respect to such Accelerated Purchase Date, and any
Acceleration Notice with respect to such Accelerated Purchase Date shall
automatically be deemed rescinded and of no further force and effect, without
prejudice to the rights of the Corporation, including without limitation its
right to provide an Acceleration Notice at any time or from time to time
thereafter. If a Cancellation Event has occurred, prior to the opening of
business on an Accelerated Purchase Date, the Corporation shall deliver to the
Agent an Officer's Certificate certifying that a Cancellation Event has
occurred. In the event that the Agent receives such notice, the Agent shall, as
promptly thereafter as is practicable, give notice thereof to the Holders, in
the manner provided in Section 1306.

                  (d) Except as expressly provided herein, no Holder shall have
the right or obligation to purchase Depositary Shares prior to the Stated
Purchase Date or from and after the date on which a Termination Event has
occurred.

                  (e) Each Holder of a Capital Unit, by his acceptance thereof,
authorizes and directs the Agent to enter into, deliver and perform the Purchase
Contracts that are part of such Capital Unit on his behalf, agrees to be bound
by the terms and provisions thereof, covenants and agrees to perform its
obligations under the Purchase Contracts evidenced by such Capital Unit, and
consents and agrees to the provisions hereof. Each Holder of a Capital Unit, by
his acceptance thereof, further covenants and agrees that, to the extent such
Holder is deemed to have elected to satisfy its obligations under the Purchase
Contracts by effecting a Debenture Settlement as provided in Section 404, and
subject to the terms thereof, redemption payments with respect to principal of
the Debentures that are part of such Capital Unit shall be applied by the Agent
in satisfaction of such Holder's obligations under such Purchase Contract on the
applicable Purchase Date.

                  (f) Upon registration of transfer of a Purchase Contract, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to this
Article Four) under the terms of this Agreement and such Purchase Contract, and
the transferor shall be released from the obligations under the Purchase
Contract so transferred.

                  (g) Each Holder of a Capital Unit, by his acceptance thereof,
authorizes the Agent to execute the Purchase Contracts evidenced by such Capital
Unit on his behalf, authorizes and directs the Agent on his behalf to take such
other action, and covenants and agrees to take such other action as may be
necessary or appropriate, or as may be required by the Agent, to effect the
provisions of this Agreement, the Capital Units and the Purchase Contracts and
appoints the Agent as his attorney-in-fact for any and all such purposes.

                                       23

Section 404.      Payment of Purchase Price.

                  (a) Subject to paragraph (b) of this Section, the Purchase
Price for the Depositary Share purchased pursuant to a Purchase Contract shall
be payable at the Corporate Trust Office of the Agent:

                  (1) at the option of the Holder of the Capital Unit evidencing
            such Purchase Contract, after receipt by the Agent of written notice
            from the Holder or from the Book-Entry Unit Depositary on behalf of
            the Holder of Book-Entry Capital Units not less than 10 days nor
            more than 20 days prior to the applicable Purchase Date, by delivery
            by such Holder or by the Book-Entry Unit Depositary on behalf of the
            Holder of Book-Entry Capital Units not later than 12:00 Noon New
            York City time on the Business Day immediately preceding the
            Purchase Date of the Purchase Price (a "Cash Settlement") to the
            Agent in immediately available funds payable to or upon the order of
            the Corporation; or

                  (2) by application of any payment received by the Agent with
            respect to the principal of the Debenture included in the Capital
            Unit of which such Purchase Contract constitutes a part, as provided
            in paragraph (f) of this Section (a "Debenture Settlement").

A Holder who fails to provide notice to the Agent as provided above that it will
make a Cash Settlement with respect to the settlement of a Purchase Contract, or
a Holder who provides such notice but does not effect a Cash Settlement in
accordance with the terms of this Section 404, will be deemed to have elected to
have the Purchase Price for the Depositary Share paid pursuant to a Debenture
Settlement.

                  (b) Notwithstanding paragraph (a) of this Section, the
Corporation shall not be entitled to sell a Depositary Share, or receive any
payment of the Purchase Price therefor, if the Corporation fails to issue the
Preferred Stock against tender by the Agent of payment therefor.

                  (c) To be effective, payment pursuant to a Cash Settlement
must be deposited with the Agent by 12:00 Noon New York City time on the
Business Day immediately preceding the Purchase Date and must be made with
respect to all (and not fewer than all) of the Purchase Contracts (i) included
in the Definitive Capital Units with respect to which a closing is being held
that are registered in the name of such Holder in the Purchase Contract Register
or (ii) included in the Book-Entry Capital Units with respect to which a closing
is being held that are beneficially owned by a single Person, as specified in
the records of the direct and indirect participants of the Depositary and as
certified in


<PAGE>

                                       24

writing by such Person, which certification shall be collected on behalf of such
Person by the direct and indirect participants in DTC through which such Person
holds interests in the Book-Entry Capital Units and will be provided to the
Agent by DTC or any direct participant of DTC, at the time payment pursuant to a
Cash Settlement is deposited with the Agent. Any attempted Cash Settlement other
than in accordance with this Section 404 shall be deemed to have not been made
and any payments made to the Agent by a Holder not complying with this Section
404 shall be returned by the Agent to such Holder.

                  (d) The Corporation shall not be obligated to issue any shares
of Preferred Stock with respect to a Purchase Contract or deliver any
certificates therefor to the Preferred Stock Depositary unless it shall have
received payment in full of the Purchase Price for the Depositary Share to be
purchased thereunder in the manner herein set forth.

                  (e) Each Acceleration Notice shall request Holders to provide
registration instructions to the Agent with respect to the Depositary Receipts
to be delivered in respect of the Depositary Shares. An Acceleration Notice
shall also request that any Holder to which Section 362 of the United States
Bankruptcy Code applies to so notify the Agent and shall be ineffective with
respect to any Holder subject to the automatic stay provisions of the United
States Bankruptcy Code. In addition, unless a Termination Event has occurred,
the Agent shall request registration instructions from each Holder, by written
request mailed to such Holder in accordance with Section 1306, with respect to
the Depositary Receipts to be delivered in respect of Depositary Shares no later
than the Regular Record Date next preceding the Stated Purchase Date. Upon
receipt by the Agent of such registration instructions, the Agent shall deliver
such instructions to the Corporation, for delivery to the Preferred Stock
Depositary pursuant to the Deposit Agreement. If no registration instructions
are received by the Agent by the second Business Day preceding the Purchase
Date, the Agent shall cause the Depositary Shares deliverable in respect of the
Purchase Contracts to be registered (i) in the case of Definitive Capital Units,
in the name of the Holder of such Capital Units as set forth in the Purchase
Contract Register or (ii) in the case of Book-Entry Capital Units, in the name
of the Depositary.

                  (f) Unless a Cancellation Event with respect to an Accelerated
Purchase Date or a Termination Event has occurred, or a Holder of a Capital Unit
has effected a Cash Settlement in satisfaction of his obligations under the
Purchase Contracts evidenced by such Capital Unit, any payment with respect to
principal of a Debenture that is received by the Agent (whether in its capacity
as Agent or as Trustee) shall be paid by the Agent to the Corporation in
satisfaction of the Holder's obligations under the Global Purchase Contract or
Purchase Contracts constituting a part of Definitive Capital Units. Any payment
that is received by the Agent (whether in its capacity as Agent or as Trustee)
with respect to interest on a Debenture related to a Purchase Contract that has
been settled in accordance


<PAGE>

                                       25

with this Section 404 shall be distributed to the Holders of Definitive Capital
Units upon surrender of the appropriate Capital Unit Certificate or in the case
of Book-Entry Capital Units, to the Holder of the Book-Entry Capital Units.

                  (g) Except as described in Section 404(a)(1), all payments to
be made by the Holders or by the Agent (whether in its capacity as Agent or
Trustee) shall be made in lawful money of the United States of America, by
certified check or wire transfer in immediately available funds in accordance
with such regulations as the Agent may reasonably establish consistent with the
provisions of this Agreement.

                  (h) Any payment deposited by a Holder hereunder with respect
to a Purchase Contract shall be held by the Agent in custody for the benefit of
the Holder and applied in satisfaction of such Holder's obligations under the
Purchase Contract, or released and delivered to the Holder upon the termination
of the Purchase Contract or failure of the Corporation to issue the Preferred
Stock against tender by the Agent of payment therefor.

 Section 405.     Issuance of Depositary Shares and Depositary Receipts.

                  Upon its receipt of payment in full of the Purchase Price for
the Depositary Shares purchased by any Holder pursuant to the foregoing
provisions of this Article, and subject to the provisions of Section 406, the
Corporation shall then cause to be delivered to the Preferred Stock Depositary a
certificate for the validly issued, fully paid and nonassessable shares of
Preferred Stock to be evidenced by the Depositary Shares so purchased,
registered in the name of the Preferred Stock Depositary in accordance with the
Deposit Agreement, together with instructions to the Preferred Stock Depositary
to register the Depositary Receipts issuable by the Preferred Stock Depositary
in the names of the Holders or such Holders' designees provided by the Holders
to the Agent and delivered to the Corporation by the Agent pursuant to Section
404. Upon the issuance of the Depositary Receipts evidencing such Depositary
Shares, registered as requested, the Agent shall then cause to be delivered such
Depositary Shares to such Holder or its designee; provided that in the case of
the settlement of a Purchase Contract constituting part of a Definitive Capital
Unit, such delivery shall be made only upon delivery to the Agent of the related
Capital Unit Certificate. The certificate evidencing such shares of Preferred
Stock shall be deemed to have been issued and the Preferred Stock Depositary
shall be deemed to have become a holder of record of such Preferred Stock as of
the close of business on the day on which payment in full under the Purchase
Contracts shall have been tendered to the Corporation by the Agent.

                  In the case of Definitive Capital Units, so long as the Agent
has not received a Capital Unit Certificate relating to such Depositary Shares
as required by the preceding


<PAGE>

                                       26

paragraph, the Agent shall not deliver such Depositary Shares to the Holder of
such Capital Unit. Upon receipt of any Capital Unit Certificate, the Agent shall
cancel such Capital Unit Certificate in accordance with Section 308 as a result
of such issuance of Depositary Receipts. If any Debentures and related
Guarantees relating to Closed Purchase Contracts constituting a part of Capital
Units remain Outstanding, MS plc shall execute and the Trustee shall
authenticate and deliver (i) in the case of Definitive Capital Units, to the
Holder thereof, in accordance with the terms of the Indenture, a new certificate
or certificates representing solely the principal amount of Debentures still
Outstanding and the related Guarantee or (ii) in the case of Book-Entry Capital
Units, if a Global Debenture not constituting part of a Book-Entry Capital Unit
has not previously been issued by MS plc to the Book-Entry Unit Depositary, a
second Global Debenture representing Debentures still Outstanding that are not
part of Capital Units. If a second Global Debenture referred to in clause (ii)
of the immediately preceding sentence has already been issued to the Book-Entry
Unit Depositary, the Book-Entry Unit Depositary shall note thereon an
appropriate increase in the number of Debentures represented by such Global
Debenture.

                  Notwithstanding the foregoing provisions of this Section to
the contrary, the Corporation shall not be required to deliver to the Preferred
Stock Depositary certificates for fractional shares of Preferred Stock.

Section 406.      Merger, Consolidation and Sales of Assets.

                  In the case of any consolidation of the Corporation with, or
merger of the Corporation with or into, any other Person, any merger of another
Person into the Corporation (other than a consolidation or merger that would not
result in any change in the terms of the Preferred Stock, if the Preferred Stock
were then outstanding) or any sale, transfer or lease of all or substantially
all of the assets of the Corporation, the Person formed by such consolidation or
resulting from such merger or that acquires such assets, as the case may be,
shall (unless the Corporation's rights and obligations under the Purchase
Contracts have been terminated) execute and deliver to the Agent an amendment of
this Agreement providing that the Holder of each Capital Unit then Outstanding
shall have the right and obligation on the Purchase Date to purchase the number
of shares, property or other assets which a holder of the number of shares of
Preferred Stock to which a Purchase Contract related was entitled to receive in
connection with such consolidation, merger, sale, transfer or lease.

Section 407.      Charges and Taxes.

                  The Corporation will pay all taxes attributable to the initial
issuance and delivery of the shares of Preferred Stock, the Depositary Shares
and the Depositary


<PAGE>

                                       27

Receipts; provided, however, that the Corporation shall not be required to pay
any tax or taxes that may be payable with respect to any exchange of or
substitution for a Capital Unit Certificate or any issuance of a Depositary
Share in a name other than that of the registered Holder of a Purchase Contract
and the Corporation shall not be required to issue or deliver such share
certificates, Capital Unit Certificates or such Purchase Contracts unless or
until the person or persons requesting the transfer or issuance thereof shall
have paid to the Corporation the amount of such tax or shall have established to
the satisfaction of the Corporation that such tax has been paid. The Agent shall
be under no obligation to pay any such tax.

Section 408.      Termination of Purchase Contracts.

                  The Purchase Contracts and the obligations and rights of the
Corporation and the Holders thereunder shall terminate if a Termination Event
occurs.

                                  ARTICLE FIVE

                                    Remedies

Section 501.      Limitation on Proceedings by Holders.

                  No Holder of any Capital Unit shall have any right by virtue
of or by availing itself of any provision of this Agreement to institute any
action or proceeding at law or in equity or in bankruptcy or otherwise upon or
under or with respect to this Agreement, or for the appointment of a trustee,
receiver, liquidator, custodian or other similar official or for any other
remedy hereunder, unless such Holder previously shall have given written notice
to the Agent, MS plc and the Corporation of Default and of the continuance
thereof and, (i) in the case of an Event of Default under the Debentures or the
Indenture, the procedures (including notice to the Trustee, MS plc and the
Corporation) described in Article Five of the Indenture have been complied with
and (ii) in the case of a Purchase Contract Default specified in clause (ii) of
the definition thereof, unless the Holders of not less than 25% of the Capital
Units then Outstanding shall have made written request upon the Agent to
institute such action or proceedings in its own name as Agent hereunder and
shall have offered to the Agent such reasonable indemnity as it may require
pursuant to Article Six, and the Agent for 60 days after its receipt of such
notice, request and offer of indemnity shall have failed to institute such
action or proceedings and no direction inconsistent with such request shall have
been given to the Agent in writing by holders of a majority of the Outstanding
Capital Units, any Holder of a Capital Unit may then (but only then) seek to
enforce the performance of the covenant or agreement with respect to which such
Purchase Contract Default exists; it being intended and expressly covenanted by
the


<PAGE>

                                       28

Holder of each Capital Unit with every other Holder and the Agent that no Holder
shall have any right by virtue of or by availing itself of any provision of this
Agreement to affect, disturb or prejudice the rights of any other Holder, or to
obtain or seek to obtain priority over or preference to any other Holder, or to
enforce any right under this Agreement, except in accordance with this Section
or the Indenture and for the equal, ratable and common benefit of all Holders.
For the protection and enforcement of the provisions of this Section, each and
every Holder of a Capital Unit and the Agent shall be entitled to such relief as
can be given either at law or in equity.

Section 502.      Restoration of Rights and Remedies.

                  If any Holder of Capital Units has instituted any proceeding
to enforce any right or remedy under this Agreement and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
such Holder, then and in every such case, subject to any determination in such
proceeding, MS plc, the Corporation, the Agent, the Trustee and such Holder
shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of MS plc, the Corporation, the Agent,
the Trustee and such Holder shall continue as though no such proceeding had been
instituted.

Section 503.      Rights and Remedies Cumulative.

                  Subject to Section 501, and except as otherwise provided with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
(i) Capital Unit Certificates in the last paragraph of Section 306 and (ii)
Global Debentures and Global Purchase Contracts in the last paragraph of Section
1106, no right or remedy herein conferred upon or reserved to the Holders of
Capital Units is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 504.      Delay or Omission Not Waiver.

                  No delay or omission of any Holder to exercise any right or
remedy accruing upon any Default shall impair any such right or remedy or
constitute a waiver of any such Default or an acquiescence therein. Every right
and remedy given by this Article or by law to the Holders may be exercised from
time to time, and as often as may be deemed expedient, by such Holders.


<PAGE>

                                       29


Section 505.      Waiver of Past Defaults.

                  The Holders of not less than a majority of the Outstanding
Capital Units may on behalf of the Holders of all of the Capital Units waive any
past Purchase Contract Default hereunder and its consequences, except, unless
theretofore cured, a Purchase Contract Default resulting from the failure of the
Corporation to issue and deliver the Preferred Stock against tender of payment
therefor or a Purchase Contract Default with respect to a covenant or provision
hereof which under Article Seven cannot be modified or amended without approval
of the Holder of each Outstanding Capital Unit affected. In the case of any such
waiver, the Holders, the Agent, the Book-Entry Unit Depositary, MS plc and the
Corporation shall be restored to their former positions and rights hereunder,
respectively.

                  Upon any such waiver, such Purchase Contract Default shall
cease to exist, for every purpose of this Agreement, but no such waiver shall
extend to any subsequent or other Purchase Contract Default or impair any right
consequent thereon unless so expressly therein provided.

Section 506.      Undertaking for Costs.

                  All parties to this Agreement agree, and each Holder of any
Capital Unit by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Agreement, or in any suit against either of the Agent
or Book-Entry Unit Depositary for any action taken, suffered or omitted by it as
Agent or Book-Entry Unit Depositary, as applicable, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section shall not apply to any suit
instituted by the Agent or the Book-Entry Unit Depositary, to any suit
instituted by any Holder of Capital Units, or group of Holders, holding in the
aggregate more than 10% of the Outstanding Capital Units, or to any suit
instituted by any Holder for enforcement of the right to purchase Depositary
Shares under the Purchase Contracts constituting a part of the Capital Units
held by such Holder.

Section 507.      Waiver of Stay or Extension Laws.

                  Each of MS plc and the Corporation covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, or plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay
or extension law wherever


<PAGE>

                                       30

enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Agreement; and MS plc and the Corporation (to the extent
that it may lawfully do so) each hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Agent, the Book-Entry Unit
Depositary, or the Holders, but will suffer and permit the execution of every
such power as though no such law had been enacted.

Section 508.      Agent May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy or other judicial proceeding relating to MS plc or the
Corporation or the property of MS plc or the Corporation or its creditors, the
Agent shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                  (1) to file and prove a claim and to file such other papers or
                  documents as may be necessary or advisable in order to have
                  the claims of the Agent (including any claim for the
                  reasonable compensation, expenses, disbursements and advances
                  of the Agent, its agents and counsel) and of the Holders
                  allowed in such judicial proceeding; and

                  (2) to collect and receive any moneys or other property
                  payable or deliverable on any such claims and to distribute
                  the same;

and any receiver, assignee, trustee, liquidator or other similar official in any
such proceeding is hereby authorized by each Holder to make such payments to the
Agent, and in the event that the Agent shall consent to the making of such
payments directly to the Holders, to pay to such Holder any amount due to it
hereunder.

 Section 509.     Suits for Enforcement.

                  In case a Purchase Contract Default has occurred, has not been
waived and is continuing, and subject to receipt by the Agent of the request
referred to in Section 501 or the direction referred to in Section 510 and the
security or indemnity referred to in Section 603(f), the Agent shall have the
right to enforce, on behalf of the Holders, the Purchase Contracts and the
covenants and agreements of the Corporation contained in the Purchase Contracts
and in this Agreement with respect to the Purchase Contracts and to proceed to
protect and enforce such rights by appropriate judicial proceedings to protect
and enforce any of such rights, either at law or in equity or in bankruptcy or
otherwise, whether for the specific enforcement of any such covenant or
agreement contained in this Agreement or in the Purchase Contracts or in aid of
the exercise of any power granted in this Agreement or


<PAGE>

                                       31

to enforce any other legal or equitable right vested in the Agent by this
Agreement or by law.

Section 510.      Control by Holders.

                  The Holders of a majority of Outstanding Capital Units shall
have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to the Agent, or exercising any power
conferred on the Agent with respect to the Purchase Contracts by this Agreement;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Agreement and provided further that (subject to the
provisions of Section 601) the Agent shall have the right to decline to follow
any such direction if the Agent, being advised by counsel, shall determine that
the action or proceeding so directed may not lawfully be taken or if the Agent
in good faith by its board of directors or the executive committee, shall
determine that the action or proceedings so directed could involve the Agent in
personal liability or if the Agent in good faith shall so determine that the
actions or forebearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of Capital Units not joining in
the giving of said direction, it being understood that (subject to Section 601)
the Agent shall have no duty to ascertain whether or not such actions or
forebearances are unduly prejudicial to such Holders.

                  Nothing in this Agreement shall impair the right of the Agent
in its discretion (but subject to Section 509) to take any action deemed proper
by the Agent and which is not inconsistent with such direction or directions by
Holders.

                                   ARTICLE SIX

Section 601.      Certain Duties and Responsibilities.

                  (a) The Agent undertakes to perform such duties and only such
            duties as are specifically set forth in this Agreement.

                  (b) No provision of this Agreement shall be construed to
            relieve the Agent from liability for its own negligent action, its
            own negligent failure to act, or its own wilful misconduct, except
            that

                  (1) the duties and obligations of the Agent with respect to
            the Capital Units shall be determined solely by the express
            provisions of this Agreement and the

                                       32

            Agent shall not be liable except for the performance of such duties
            and obligations as are specifically set forth in this Agreement, and
            no implied covenants or obligations shall be read into this
            Agreement against the Agent; and

                  (2) in the absence of bad faith on its part, the Agent may
            conclusively rely, as to the truth of the statements and the
            correctness of the opinions expressed therein, upon any statements,
            certificates or opinions furnished to the Agent and conforming to
            the requirements of this Agreement, but in the case of any such
            statements, certificates or opinions that by any provision hereof
            are specifically required to be furnished to the Agent, the Agent
            shall be under a duty to examine the same to determine whether or
            not they conform to the requirements of this Agreement.

                  (c) The Agent shall not be liable for any error of judgment
            made in good faith by a Responsible Officer of the Agent, unless it
            shall be proved that the Agent was negligent in ascertaining the
            pertinent facts.

                  (d) The Agent shall not be liable with respect to any action
            taken or omitted to be taken by it in good faith in accordance with
            the direction of the Holders of a majority in number of Outstanding
            Capital Units relating to the time, method and place of conducting
            any proceeding for any remedy available to the Agent, or exercising
            any power conferred upon the Agent, under this Agreement.

                  (e) No provision of this Agreement shall require the Agent to
            expend or risk its own funds or otherwise incur any financial
            liability in the performance of any of its duties hereunder, or in
            the exercise of any of its rights or powers, if it shall have
            reasonable grounds for believing that repayment of such funds or
            adequate indemnity against such risk or liability is not reasonably
            assured to it.

                  (f) Whether or not therein expressly so provided, every
            provision of this Agreement relating to the conduct or affecting the
            liability of or affording protection to the Agent shall be subject
            to the provisions of this Section.

                  (g) The Agent is acting solely as agent for MS plc and the
            Corporation hereunder and owes no fiduciary duties to any person by
            virtue of this Agreement.

Default of which a Responsible Officer of the Agent assigned to its Corporate
Trustee Administration Department has actual knowledge, and except with respect
to a Purchase Contract Default under the Purchase Contracts existing on the
Purchase Date, in which event, as promptly as practicable thereafter, the Agent

                  (c) the Agent may consult with counsel and the written advice
            of such counsel or any Opinion of Counsel shall be full and complete
            authorization and protection with respect to any action taken,

            thereon in accordance with such advice or Opinion of Counsel;

                  (e) the Agent may execute any of the powers hereunder or
            perform any duties hereunder either directly or by or through agents
            or attorneys and the Agent shall not be responsible for any
            misconduct or negligence on the part of any such agent or attorney

                  (f) the Agent shall be under no obligation to exercise any of
            the rights or powers vested in it by this Agreement at the request,

            unless such Holders shall have offered to the Agent reasonable
            security or indemnity against the costs, expenses and liabilities
            that might be incurred by it in compliance with such request or
            direction;

                  (g) the Agent shall not be liable for any action taken or
            omitted by it in good faith and believed by it to be authorized or

Section 604.      Not Responsible for Recitals or Issuance of Capital Units.

                  The recitals contained herein, in the Indenture and in the
Capital Units, except the Trustee's and Agent's certificates of authentication,
shall be taken as the statements of MS plc or the Corporation, as the case may
be, and neither the Agent nor any Authenticating Agent assumes any
responsibility for their correctness. The Agent makes no representations as to
the validity or sufficiency of this Agreement or of the Capital Units. Neither
the Agent nor any Authenticating Agent shall be accountable for the use or
application by MS plc or the Corporation of the proceeds with respect to Capital
Units or be responsible for exercising any remedy hereunder on behalf of the
Holders, except as expressly provided in this Agreement.

Section 605.      May Hold Capital Units.

                  The Agent, the Trustee, any Authenticating Agent, any Purchase
Contract Registrar or any other agent of MS plc, the Corporation, the Trustee or
the Agent, in its individual or any other capacity, may become the owner or
pledgee of Capital Units and may otherwise deal with MS plc and the Corporation
and receive, collect, hold and retain collections from MS plc and the
Corporation with the same rights it would have if it were


<PAGE>

                                       35

not Authenticating Agent, Purchase Contract Registrar or such other agent, the
Trustee or the Agent.

Section 606.      Money Held in Trust.

                  Money held by the Agent in trust hereunder need not be
segregated from other funds held by the Agent, except to the extent required by
law. The Agent shall be under no obligation to invest or pay interest on any
money received by it hereunder, except as otherwise agreed with MS plc and the
Corporation. Any interest accrued on funds deposited with the Agent or any
Paying Agent under this Agreement shall be paid to MS plc and the Corporation
from time to time and the Holders of Capital Units (whether or not any Purchase
Contracts are to be redeemed with such funds) shall have no claim to any such
interest.

Section 607.      Compensation and Reimbursement.

                  MS plc and the Corporation agree:

                  (a) to pay to the Agent from time to time reasonable
            compensation for all services rendered by it hereunder (which
            compensation shall not be limited by any provision of law with
            regard to the compensation of a trustee of an express trust),

                  (b) except as otherwise expressly provided herein, to
            reimburse the Agent and any predecessor Agent upon its request for
            all reasonable expenses, disbursements and advances incurred or made
            by the Agent in accordance with any provision of this Agreement
            (including the reasonable compensation and the expenses and
            disbursements of its agents and counsel), except any such expense,
            disbursement or advance as may be attributable to its negligence or
            bad faith; and

                  (c) to indemnify the Agent and any predecessor Agent for, and
            to hold it harmless against, any loss, liability or expense incurred
            without negligence or bad faith on its part, arising out of or in
            connection with the acceptance or administration of this Agreement
            and its duties hereunder, including the costs and expenses of
            defending itself against or investigating any claim of liability in
            connection with the exercise or performance of any of its powers or
            duties hereunder.

                  The obligations of MS plc and the Corporation under this
Section to compensate and indemnify the Agent and any predecessor Agent and to
pay or reimburse the Agent and any predecessor Agent for expenses, disbursements
and advances shall constitute additional indebtedness hereunder and shall
survive the satisfaction and discharge


<PAGE>

                                       36

of this Agreement. Such additional indebtedness shall be a senior claim to that
of the Capital Units upon all property and funds held or collected by the Agent
as such, except funds held in trust for the benefit of the Holders of Capital
Units, and the Capital Units are hereby subordinated to such senior claim.

Section 608.      Corporate Agent Required; Eligibility.

                  There shall at all times be an Agent hereunder which shall be
a corporation organized and doing business under the laws of the United States
of America, any State thereof or the District of Columbia, having, together with
its parent, a combined capital and surplus of at least $50,000,000, subject to
supervision or examination by Federal, State or District of Columbia authority
and willing to act on reasonable terms. Such corporation shall have its
principal place of business in the Borough of Manhattan, The City of New York,
if there be such a corporation in such location willing to act upon reasonable
and customary terms and conditions. If such corporation, or its parent,
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. The Agent hereunder shall at all times
be the Book-Entry Unit Depositary hereunder and the Trustee under the Indenture,
subject to receipt of an Opinion of Counsel that the same Person is precluded by
law from acting in such capacities. If at any time the Agent shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

Section 609.      Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Agent and no appointment
            of a successor Agent pursuant to this Article shall become effective
            until the acceptance of appointment by the successor Agent in
            accordance with the applicable requirements of Section 610.

                  (b) The Agent may resign by giving written notice thereof to
            MS plc and the Corporation and the Holders, in accordance with
            Section 1305 and Section 1306, 60 days prior to the effective date
            of such resignation. The Agent may be removed at any time upon 60
            days' notice by the filing with it of an instrument in writing
            signed on behalf of MS plc and the Corporation and specifying such
            removal and the date when it is intended to become effective. If the
            instrument of acceptance by a successor Agent required by Section
            610 shall not have been delivered to the Agent within 30 days after
            the giving of such notice of resignation, the resigning Agent


<PAGE>

                                       37

            may petition any court of competent jurisdiction for the appointment
            of a successor Agent.

                  (c) If at any time

                  (1) the Agent shall cease to be eligible under Section 608, or
            shall cease to be eligible as Book-Entry Unit Depositary hereunder
            or as Trustee under the Indenture, and shall fail to resign after
            written request therefor by MS plc, the Corporation or by any
            Holder, or

                  (2) the Agent shall become incapable of acting with respect to
            the Capital Units or shall be adjudged a bankrupt or insolvent, or a
            receiver or liquidator of the Agent or of its property shall be
            appointed or any public officer shall take charge or control of the
            Agent or of its property or affairs for the purpose of
            rehabilitation, conservation or liquidation, then, in any such case,
            (i) MS plc or the Corporation, by Board Resolution, may remove the
            Agent and appoint a successor Agent, or (ii) any Holder who has been
            a bona fide Holder of a Capital Unit for at least six months may, on
            behalf of himself and all others similarly situated, petition any
            court of competent jurisdiction for the removal of the Agent and the
            appointment of a successor Agent or Agents. Such court may
            thereupon, after such notice, if any, as it may deem proper and
            prescribe, remove the Agent and appoint a successor Agent.

                  (d) If the Agent shall resign, be removed or become incapable
            of acting, or if a vacancy shall occur in the office of Agent for
            any cause, with respect to the Capital Units, MS plc and the
            Corporation, by Board Resolution, shall promptly appoint a successor
            Agent or Agents (other than the Corporation or MS plc) and shall
            comply with the applicable requirements of Section 610. If no
            successor Agent shall have been so appointed by MS plc and the
            Corporation and accepted appointment in the manner required by
            Section 610, any Holder who has been a bona fide Holder of a Capital
            Unit for at least six months may, on behalf of himself and all
            others similarly situated, petition any court of competent
            jurisdiction for the appointment of a successor Agent. 

                  (e) MS plc and the Corporation shall give, or shall cause such
            successor Agent to give, notice of each resignation and each removal
            of the Agent and each appointment of a successor Agent to all
            Holders of Capital Units in accordance with Section 1306. Each
            notice shall include the name of the successor Agent and the address
            of its Corporate Trust Office.

Section 610.      Acceptance of Appointment by Successor.


<PAGE>

                                       38

                  (a) In case of the appointment hereunder of a successor Agent,
            every such successor Agent so appointed shall execute, acknowledge
            and deliver to MS plc and the Corporation and to the retiring Agent
            an instrument accepting such appointment, and thereupon the
            resignation or removal of the retiring Agent shall become effective
            and such successor Agent, without any further act, deed or
            conveyance, shall become vested with all the rights, powers,
            agencies and duties of the retiring Agent, with like effect as if
            originally named as Agent hereunder; but, on the request of MS plc,
            the Corporation or the successor Agent, such retiring Agent shall,
            upon payment of all amounts due and payable to it pursuant to
            Section 607, execute and deliver an instrument transferring to such
            successor Agent all the rights and powers of the retiring Agent and
            shall duly assign, transfer and deliver to such successor Agent all
            property and money held by such retiring Agent hereunder. Any
            retiring Agent shall, nonetheless, retain a prior claim upon all
            property or funds held or collected by such Agent to secure any
            amounts then due it pursuant to Section 607.

                  (b) Upon request of any such successor Agent, MS plc and the
            Corporation shall execute any and all instruments for more fully and
            certainly vesting in and confirming to such successor Agent all such
            rights, powers and agencies referred to in paragraph (a) of this
            Section.

                  (c) No successor Agent shall accept its appointment unless at
            the time of such acceptance such successor Agent shall be eligible
            under this Article.

                  (d) Upon acceptance of appointment by any successor Agent as
            provided in this Section, MS plc and the Corporation shall give
            notice thereof to the Holders of Capital Units in accordance with
            Section 1306. If the acceptance of appointment is substantially
            contemporaneous with the resignation of the Agent, then the notice
            called for by the preceding sentence may be combined with the notice
            called for by Section 609. If MS plc and the Corporation fail to
            give such notice within ten days after acceptance of appointment by
            the successor Agent, the successor Agent shall cause such notice to
            be given at the expense of MS plc and the Corporation.

Section 611.      Merger, Conversion, Consolidation or Succession to Business.

                  Any corporation into which the Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Agent shall be a
party, or any corporation succeeding to all or substantially all the agency
business of the Agent, shall be the successor of the Agent hereunder, without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, provided that such corporation shall be otherwise eligible
under this


<PAGE>

                                       39

Article. In case any Capital Unit Certificates shall have been countersigned and
executed, but not delivered, by the Agent then in office, any successor by
merger, conversion or consolidation to such Agent may adopt such
countersignature and execution and deliver the Capital Unit Certificates so
countersigned and executed with the same effect as if such successor Agent had
itself countersigned and executed such Capital Units.

Section 612.      Appointment of Authenticating Agent.

                  At any time when any of the Capital Units remain Outstanding
the Agent may, by an instrument in writing, appoint an Authenticating Agent or
Agents with respect to the Purchase Contracts that may be authorized to act on
behalf of the Agent to countersign, execute and deliver the Purchase Contracts
issued upon exchange, registration of transfer or pursuant to Section 306 and
Purchase Contracts so countersigned, executed and delivered shall be entitled to
the benefits of this Agreement and shall be valid and obligatory for all
purposes as if countersigned by the Agent hereunder. Wherever reference is made
in this Agreement to the countersignature, execution and delivery of Purchase
Contracts by the Agent or the Agent's countersignature, such references shall be
deemed to include countersignature, execution and delivery on behalf of the
Agent by an Authenticating Agent and a countersignature and execution executed
on behalf of the Agent by an Authenticating Agent. Each Authenticating Agent
shall be acceptable to MS plc and the Corporation and shall at all times be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to act as Authenticating Agent, subject to supervision or examination by
Federal or State or District of Columbia authority and having, together with its
parent, a combined capital and surplus of not less than $50,000,000. If such
Authenticating Agent, or its parent, publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the agency business of an Authenticating Agent, shall continue
to be an Authenticating Agent, without the execution or filing of any paper or
any further act on the part of the Agent or the Authenticating Agent, provided
that such corporation shall be otherwise eligible under this Section.


<PAGE>

                                       40


                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Agent and to MS plc and the Corporation. The Agent
may at any time terminate the agency of an Authenticating Agent by giving
written notice thereof to such Authenticating Agent and to MS plc and the
Corporation. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Agent may
appoint a successor Authenticating Agent which shall be acceptable to MS plc and

hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section. No Authenticating Agent
shall have any responsibility or liability for any action taken by it as such at
the direction of the Agent.

                  The provisions of Sections 307, 604 and 605 shall be
applicable to each Authenticating Agent.

Section 613.      MS plc and the Corporation to Furnish Agent Names and
                  Addresses of Holders.

                  MS plc and the Corporation will furnish or cause to be
furnished to the Agent

                  (a) not later than 15 days after each Regular Record Date in
            each year, a list, in such form as the Agent may reasonably require,
            of the names and addresses of the Holders as of such Regular Record
            Date, and

                  (b) at such other times as the Agent may request in writing,
            within 30 days after the receipt by MS plc and the Corporation of
            any such request, a list of similar form and content as of a date
            not more than 15 days prior to the time such list is furnished;

provided that no such list need be furnished if the Agent shall be the Purchase
Contract Registrar and the registrar under the Indenture.

Section 614.      Preservation of Information; Communications to Holders.

                  (a) The Agent shall preserve, in as current a form as is
            reasonably practicable, the names and addresses of Holders contained
            in the most recent list furnished to the Agent as provided in
            Section 613 and the names and addresses of Holders received by the
            Agent in its capacity as Purchase Contract Registrar and the
            registrar under the Indenture. The Agent may destroy any list
            furnished to it as provided in Section 613 upon receipt of a new
            list so furnished.

                  (b) If three or more Holders (herein referred to as
            "applicants") apply in writing to the Agent, and furnish to the
            Agent reasonable proof that each such


<PAGE>

                                       42

            applicant has owned a Capital Unit for a period of at least six
            months preceding the date of such application, and such application
            states that the applicants desire to communicate with other Holders
            with respect to their rights under this Agreement or under the
            Capital Units and is accompanied by a copy of the form of proxy or
            other communication that such applicants propose to transmit, then
            the Agent shall, within five Business Days after the receipt of such
            application, at its election either (i) afford such applicants
            access to the information preserved at the time by the Agent in
            accordance with Section 614(a) or (ii) inform such applicants as to
            the approximate number of Holders whose names and addresses appear
            in the information preserved at the time by the Agent, and as to the
            approximate cost of mailing to such Holders the form of proxy or
            other communication, if any, specified in such application.

                  If the Agent shall elect not to afford such applicants access
            to such information, the Agent shall, upon the written request of
            such applicants, mail to each Holder whose name and address appears
            in the information preserved at the time by the Agent, a copy of the
            form of proxy or other communication that is specified in such
            application, with reasonable promptness after a tender to the Agent
            of the material to be mailed and of payment, or provision for
            payment, of the reasonable expenses of mailing, unless within five
            days after such tender, the Agent shall mail to such applicants a
            written statement to the effect that in the opinion of the Agent,
            such mailing would be contrary to the best interests of the Holders
            or would be in violation of applicable law. Thereafter, the Agent
            shall be relieved of any obligation or duty to such applicants with
            respect to their application.

                  (c) Every Holder of Capital Units, by his acceptance thereof,
            agrees with MS plc, the Corporation and the Agent that none of MS
            plc, the Corporation, the Agent nor any agent of any of them shall
            be held accountable by reason of the disclosure of any such
            information as to the names and addresses of the Holders in
            accordance with Section 614(b), regardless of the source from which
            such information was derived, and that the Agent shall not be held
            accountable by reason of mailing any material pursuant to a request
            made under Section 614(b).

Section 615.      No Obligation of Holder.

                  Except to the extent otherwise provided in this Agreement, the
Agent assumes no obligations and shall not be subject to any liability under
this Agreement or any Purchase Contract with respect to the obligations of the
Holder of a Capital Unit thereunder. Each of MS plc and the Corporation agrees,
and each Holder of a Capital Unit Certificate, by his acceptance thereof, shall
be deemed to have agreed, that the Agent's execution of the Purchase Contracts
evidenced by the Capital Unit Certificates shall be solely as agent and


<PAGE>

                                       43

attorney-in-fact for the Holders, and that the Agent shall have no obligation to
perform such Purchase Contracts on behalf of the Holders, except to the extent
provided in this Article.

Section 616.      Tax Compliance.

                  (a) The Agent, on its own behalf and on behalf of MS plc and
            the Corporation, will comply with all applicable certification,
            information reporting and withholding (including "backup"
            withholding) requirements imposed by applicable U.K. and or United
            States, federal and New York State tax laws, regulations or
            administrative practice with respect to (i) the Debentures or the
            Purchase Contracts or (ii) the issuance, delivery, holding,
            transfer, redemption or exercise of rights under the Debentures or
            the Purchase Contracts. Such compliance shall include, without
            limitation, the preparation and timely filing of required returns
            and the timely payment of all amounts required to be withheld to the
            appropriate taxing authority or its designated agent. MS plc and the
            Corporation will provide to the Agent such information as it may
            reasonably request in order to comply with this Section.

                  (b) The Agent shall comply with any direction received from MS
            plc or the Corporation with respect to the application of such
            requirements to particular payments or holders or in other
            particular circumstances, and may for purposes of this Agreement
            rely on any such direction in accordance with the provisions of
            Section 601(b)(2) hereof.

                  (c) The Agent shall maintain all appropriate records
            documenting compliance with such requirements, and shall make such
            records available on request at reasonable times during normal
            business hours to MS plc and the Corporation or to their authorized
            representatives duly authorized in writing.

                  (d) The portion of the purchase price of the Capital Units
            allocable to the Debentures shall equal the amount payable at
            maturity of the Debenture. MS plc and the Holders agree not to file
            any tax returns, or take a position with any tax authority, that is
            inconsistent with such allocation or that is inconsistent with the
            characterization of the Debentures as debt.

                             Supplemental Agreements

Section 701.      Supplemental Agreements Affecting Purchase
                  Contracts Without Consent of Holders.

                  Without the consent of any Holders, MS plc and the
Corporation, each when authorized by a Board Resolution or Officer's
Certificate, and the Agent and the Book-Entry Unit Depositary, at any time and
from time to time, may enter into one or more agreements supplemental hereto, in
form satisfactory to the Agent and the Book-Entry Unit Depositary, for any of
the following purposes:

                  (1) to evidence the succession of another Person to the
            Corporation or MS plc and the assumption by any such successor of
            the covenants of the Corporation or MS plc herein, in the case of
            the Corporation, with respect to and affecting the Purchase
            Contracts and in the Purchase Contracts, and in the case of MS plc
            and the Corporation, with respect to the covenants and conditions of
            this Agreement to be performed by MS plc or the Corporation; or

                  (2) to evidence and provide for the acceptance of appointment
            hereunder by a successor Agent or Book-Entry Unit Depositary, as
            applicable, with respect to the Capital Units; or

                  (3) to add to the covenants of MS plc, the Corporation, the
            Agent or the Book-Entry Unit Depositary such further covenants,
            restrictions, conditions or provisions as MS plc, the Corporation,
            the Agent and the Book-Entry Unit Depositary shall consider to be
            for the protection of the Holders, and to make the occurrence, or
            the occurrence and continuance, of a default in any such additional
            covenants, restrictions, conditions or provisions of the Corporation
            a Purchase Contract Default permitting the enforcement of all or any
            of the several remedies provided in this Agreement as herein set
            forth; provided that in respect of any such additional covenant,
            restriction, condition or provision such supplemental agreement may
            provide for a particular period of grace after default (which period
            may be shorter or longer than that allowed in the case of other
            defaults) or may provide for an immediate enforcement upon such a
            Purchase Contract Default or may limit the remedies available to the
            Holders upon such a Purchase Contract Default or may limit the right
            of the Holders to waive such Purchase Default; or

                                       45

                  (4) to comply with the Securities Act of 1933, as amended, the
            Exchange Act or the Investment Company Act as of 1940, as amended;
            or

                  (5) to cure any ambiguity, to correct or supplement any
            provision herein with respect to and affecting the Purchase
            Contracts that may be inconsistent with any other provision herein,
            or to modify, alter, amend or supplement any other provisions with
            respect to matters or questions arising under this Agreement with
            respect to and affecting the Purchase Contracts; provided that such
            action shall not adversely affect the interests of the Holders in
            any material respect.

Section 702.      Supplemental Agreements Affecting
                  Purchase Contracts with Consent of Holders.

                  With the consent of the Holders of not less than a majority of
the Outstanding Capital Units, by Act of said Holders delivered to the
Corporation and the Agent, the Corporation and MS plc, each when authorized by a
Board Resolution or Officer's Certificate, and the Agent and the Book-Entry Unit
Depositary may enter into an agreement or agreements supplemental hereto for the
purpose of modifying in any manner the terms of the Purchase Contracts or this
Agreement with respect to the Purchase Contracts or the rights of the Holders of
Capital Units with respect to the Purchase Contracts; provided, however, that no
such supplemental agreement shall, without the consent of the Holder of each
Outstanding Capital Unit affected thereby,

                  (1) impair the right to institute suit for the enforcement of
            any Purchase Contract, or

                  (2) reduce the percentage of the Outstanding Capital Units,
            the consent of whose Holders is required for any modification or
            amendment of the provisions of this Agreement relating to the
            Purchase Contracts or for any waiver of any Purchase Contract
            Defaults hereunder and their consequences provided for in this
            Agreement relating to the Purchase Contracts, or

                  (3) modify or affect (in any manner materially adverse to the
            Holders) the Holders' rights and obligations under the Purchase
            Contracts, or

                  (4) modify or affect (in any manner materially adverse to the
            holders) the terms of the Preferred Stock or the Depositary Shares
            (determined as if the Preferred Stock and Depositary Shares were
            outstanding);


<PAGE>

                                       46

provided that the Holders of not less than 66-2/3% of the Capital Units
Outstanding at the time of an issuance of shares of a class of stock that ranks
prior to the Preferred Stock as to dividends or upon liquidation may consent to
such an issuance, and such issuance, if so consented to, will not result in a
Cancellation Condition and will not affect the rights of Holders under the
Purchase Contracts.

                  It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental agreement,
but it shall be sufficient if such Act shall approve the substance thereof.

Section 703.      Execution of Supplemental Agreements.

                  In executing, or accepting the additional agencies or duties
created by, any supplemental agreement permitted by this Article or the
modifications thereby of the agencies or duties created by this Agreement, each
of the Agent and the Book-Entry Unit Depositary shall be entitled to receive and
(subject to Sections 601 and 1201, respectively) shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental agreement is authorized or permitted by this Agreement. Each of the
Agent and the Book-Entry Unit Depositary may, but shall not be obligated to,
enter into any such supplemental agreement that affects the Agent's or the
Book-Entry Unit Depositary's respective rights, duties or immunities under this
Agreement or otherwise.

Section 704.      Effect of Supplemental Agreements.

                  Upon the execution of any supplemental agreement under this
Article, this Agreement shall be modified in accordance therewith, and such
supplemental agreement shall form a part of this Agreement for all purposes; and
every Holder of Capital Unit Certificates, or Book-Entry Capital Units
represented by Global Debentures and Global Purchase Contracts, theretofore or
thereafter authenticated, countersigned, executed and delivered hereunder and
under the Indenture shall be bound thereby.

Section 705.      Reference to Supplemental Agreements.

                  Capital Unit Certificates, Debentures and Purchase Contracts
authenticated, countersigned, executed and delivered after the execution of any
supplemental agreement pursuant to this Article may, and shall if required by
the Agent, bear a notation in form approved by the Agent as to any matter
provided for in such supplemental agreement. If MS plc or the Corporation shall
so determine, new Capital Unit Certificates, Debentures and Purchase Contracts
so modified as to conform, in the opinion of the Agent, MS plc and the
Corporation, to any such supplemental agreement may be prepared and executed by


<PAGE>

                                       47

MS plc and the Corporation and authenticated, executed, countersigned and
delivered by the Trustee and the Agent, as applicable, in exchange for
Outstanding Capital Unit Certificates, Debentures and Purchase Contracts.

Section 801.      Covenant Not to Merge, Consolidate,
                  Sell or Convey Property Except Under Certain Conditions.

                  Each of MS plc and the Corporation covenants that it will not
merge or consolidate with any other corporation or sell, convey or lease all or
substantially all of its assets to any Person, firm or corporation, except that
MS plc or the Corporation may merge or consolidate with, or sell, convey or
lease all or substantially all of its assets to, any other corporation, provided
that (i) either MS plc or the Corporation, as the case may be, shall be the
continuing corporation, or the successor corporation (if other than MS plc or
the Corporation, as the case may be) shall be a corporation organized and
existing under the laws of the United States of America or a state thereof or
the District of Columbia (with respect to the Corporation) or England and Wales
(with respect to MS plc) and such corporation shall (a) in the case of the
Corporation, execute and deliver to the Agent an amendment to this Agreement
with respect to the Purchase Contracts, as provided in Section 406 hereof, and
(b) in the case of both MS plc and the Corporation, assume the due and punctual
performance and observance of all of the covenants and conditions of this
Agreement to be performed by MS plc or the Corporation, as the case may be, by
supplemental agreement in form satisfactory to the Agent and the Book-Entry Unit
Depositary, executed and delivered to the Agent and the Book-Entry Unit
Depositary by such corporation, and (ii) none of MS plc, the Corporation or such
successor corporation, as the case may be, immediately after such merger or
consolidation, or such sale or conveyance, shall be in default in the
performance of any such covenant or condition.

Section 802.      Rights and Duties of Successor Corporation.

                  In case of any such consolidation, merger, sale or conveyance
and upon any such assumption by the successor corporation, such successor
corporation shall succeed to and be substituted for MS plc or the Corporation,
as the case may be, with the same effect as if it had been named herein as MS
plc or the Corporation, as the case may be. Such successor corporation thereupon
may cause to be signed, and may issue (subject to the provisions of the
Indenture) either in its own name or in the name of Morgan Stanley Finance plc
(in the case of MS plc) or Morgan Stanley Group Inc. (in the case of


<PAGE>

                                       48

the Corporation) any or all of the Capital Unit Certificates, Debentures and
Purchase Contracts issuable hereunder which theretofore shall not have been
signed by MS plc (with respect to the Debentures constituting part of such
Capital Units) or the Corporation (with respect to the Purchase Contracts
constituting part of such Capital Units), as the case may be, and delivered to
the Agent or the Book-Entry Unit Depositary; and, upon the order of such
successor corporation, instead of MS plc or the Corporation, as the case may be,
and subject to all the terms, conditions and limitations in this Agreement
prescribed, the Trustee and the Agent shall authenticate, countersign, execute
and deliver, as applicable, any Capital Unit Certificates, Debentures and
Purchase Contracts that previously shall have been signed and delivered by the
officers of MS plc (with respect to the Debentures constituting part of such
Capital Units) or the Corporation (with respect to Purchase Contracts
constituting part of such Capital Units), as the case may be, to the Trustee and
the Agent for authentication, execution and countersignature, and any Capital
Unit Certificate, Debenture and Purchase Contract evidencing Capital Units which
such successor corporation thereafter shall cause to be signed and delivered to
the Trustee and the Agent for such purpose. All the Purchase Contracts so issued
shall in all respects have the same legal rank and benefit under this Agreement
as the Purchase Contracts theretofore or thereafter issued in accordance with
the terms of this Agreement as though all of such Purchase Contracts had been
issued at the date of the execution hereof.

                  In case of any such consolidation, merger, sale or conveyance
such change in phraseology and form (but not in substance) may be made in the
Capital Unit Certificates and Purchase Contracts thereafter to be issued as may
be appropriate.

Section 803.      Opinion of Counsel to Agent
                  and the Book-Entry Unit Depositary.

                  The Agent and the Book-Entry Unit Depositary, subject to
Sections 601 and 603 and Sections 1201 and 1203, respectively, may receive an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale or conveyance, and any such assumption, complies with the provisions of
this Article.

Section 902.      Maintenance of Office or Agency.

                  MS plc and the Corporation will maintain in the Borough of

Certificates may be presented or surrendered for payment or acquisition of
Depositary Shares, where Capital Unit Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon MS
plc and the Corporation in respect of the Capital Units and this Agreement may
be served; provided, however, that with respect to Book-Entry Capital Units, MS
plc or the Corporation will maintain in the place of payment of the Global
Debenture constituting a part of such Book-Entry Capital Units an office or
agency where such Global Debenture may be presented or surrendered for payment,
in accordance with the provisions of the Indenture. MS plc and the Corporation
hereby initially appoint the Agent its office or agency in the Borough of
Manhattan, The City of New York for each of said purposes. MS plc and the
Corporation will give prompt written notice to the Agent of the location, and
any change in the location, of such office or agency. If at any time MS plc or
the Corporation shall fail to maintain any such required office or agency or
shall fail to furnish the Agent with the name and address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Agent, and MS plc and the Corporation hereby
appoint the Agent as its agent to receive all such presentations, surrenders,
notices and demands.

                  MS plc and the Corporation may also from time to time
designate one or more other offices or agencies where Debentures, Purchase
Contracts and Capital Unit Certificates may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve MS plc or the Corporation of their respective obligations to maintain an
office or agency in the Borough of Manhattan, The City of New York, for such
purposes. MS plc and the Corporation will give prompt written notice to the
Agent of any such designation or rescission and of any change in the location of
any such other office or agency. MS plc and the Corporation hereby designate as
the place of

Corporate Trust Office of the Agent and appoint the Agent at its Corporate Trust
Office as paying agent in such city.

Section 903.      Money for Payments to Be Held in Trust.

                  Any money deposited with the Agent, in trust for payment with
respect to any Capital Unit, remaining unclaimed for two years after such
payment has become due and payable shall be paid to MS plc or the Corporation on
request of MS plc or the Corporation, as the case may be, pursuant to an
Officer's Certificate; and the Holder of such Capital Unit shall thereafter, as
an unsecured general creditor, look only to MS plc or the Corporation, as the
case may be, for payment thereof, and all liability of the Agent with respect to
such trust money shall thereupon cease.

                  In the event that (i) a Termination Event has not occurred,
(ii) the Corporation has issued Preferred Stock against tender of payment for
the Depositary Shares evidencing such Preferred Stock and (iii) a Holder of a
Capital Unit Certificate fails to present and surrender the appropriate Capital
Unit Certificate to the Agent, the Depositary Receipts issuable in respect of
the Depositary Shares to be purchased pursuant to the Purchase Contracts
evidenced by such Capital Unit Certificate, together with any distributions
thereon (and, if an effective Cash Settlement with respect to the obligations
under such Purchase Contracts has been made, payments in respect of principal of
the Debentures that are part of such Capital Units), shall be held by the Agent,
in trust, for the benefit of such Holder, until such Capital Unit Certificate is
presented and surrendered or such Holder delivers to the Agent, the Trustee, MS
plc and the Corporation (i) evidence to their satisfaction that such certificate
has been destroyed, lost or stolen and (ii) such security or indemnity as may be
required by them to hold each of them and any agent of any of them harmless. In
the event such Capital Unit Certificate is not presented and surrendered or such
Holder does not satisfy the applicable conditions specified in the preceding
sentence on or prior to the date two years after the date of settlement of the
related Purchase Contract, any distributions received by the Agent with respect
to the Depositary Receipts representing the Depositary Shares issued in respect
of the Capital Unit Certificates shall be paid to the Corporation, on the
request of the Corporation pursuant to an Officer's Certificate, and the Holders
of such Capital Unit shall thereafter, as unsecured general creditors, look only
to the Corporation for payment thereof and all liability of the Agent with
respect to such trust assets shall thereafter cease. Any cash held by the Agent
in respect of the principal of the Debentures shall be distributed by the Agent
in accordance with the provisions of the succeeding paragraph.

                                       51

                  In the event (i) a Termination Event has occurred, (ii) the
Corporation fails to issue Preferred Stock against tender of payment for the
Depositary Shares evidencing such Preferred Stock or (iii) a Holder of a Capital
Unit has properly effected a Cash Settlement on the Purchase Date, any money
deposited with the Agent or Trustee for payment of principal and interest, if
any, on any Debenture evidenced by such Capital Unit shall be held by the Agent,
in trust, for the benefit of such Holder, until a Capital Unit Certificate is
presented and surrendered or such Holder delivers to the Agent, the Trustee, MS
plc and the Corporation (i) evidence to their satisfaction that such certificate
has been destroyed, lost or stolen and (ii) such security or indemnity as may be
required by them to hold each of them and any agent of any of them harmless. In
the event such Capital Unit Certificate is not presented and surrendered or such
Holder does not satisfy the applicable conditions specified in the preceding
sentence on or prior to the date two years after the repayment of the principal
of the Debentures, any money deposited with the Agent for payment of principal
on such Debenture evidenced by such Capital Unit Certificate shall be paid to MS
plc (or the Corporation, if the Corporation deposited such money pursuant to the
Guarantee) upon the request of MS plc or the Corporation, as the case may be,
pursuant to an Officer's Certificate and the Holders of such Debentures shall
thereafter, as unsecured general creditors, look only to MS plc or the
Corporation, as the case may be, for payment thereof and all liability of the
Agent with respect to such trust money shall thereupon cease.

Section 904.      Rating Agencies.

                  The Corporation shall cause to be done all things necessary to
obtain publicly available ratings (including any "implied" rating) of its
Long-Term Senior Debt from Moody's and S&P at the close of business on the day
that is five Business Days prior to each Purchase Date and at the opening of
business on the Stated Purchase Date or, if such day is not a Business Day, at
the close of business on the next preceding Business Day, including, without
limitation, if Moody's or S&P, or both, no longer rates the Long-Term Senior
Debt or ceases to exist, selecting a substitute Rating Agency for such purpose.

Section 905.      Corporation to Reserve Preferred Stock.

                  The Corporation shall at all times prior to the Purchase Date
reserve and keep available, free from preemptive rights, out of its authorized

Stock issuable against tender of payment for the Depositary Shares relating to
such shares of Preferred Stock with respect to all Purchase Contracts

Section 906.      Covenants as to Preferred Stock.

                  The Corporation covenants that all shares of Preferred Stock
that may be issued against tender of payment for the Depositary Shares relating
to such shares of Preferred Stock in respect of any Outstanding Purchase
Contract will, upon issuance, be duly authorized and validly issued and fully
paid and nonassessable. The Corporation further covenants and agrees not to take
any action that will cause any Preferred Stock to be issued prior to a Purchase
Date or to file any amendment to the Certificate of Designation designating the
Preferred Stock, or to take any other action that would change the terms of the
Preferred Stock or the Depositary Shares relating to such Preferred Stock,
except as permitted by this Agreement.

 Section 907.     Statements of Officers of MS plc
                  and the Corporation as to Default.

                  Each of the Corporation and MS plc will deliver to the Agent,
within 120 days after the end of each fiscal year of the Corporation or MS plc,
as the case may be, ending after the date hereof, an Officer's Certificate
stating whether or not to the best knowledge of the signers thereof the
Corporation or MS plc, as the case may be, is in default in the performance and
observance of any of the terms, provisions and conditions hereof, and, if the
Corporation or MS plc shall be in default, specifying all such defaults and the
nature and status thereof of which they may have knowledge.

                      Redemption of the Purchase Contracts

Section 1001.     Optional Redemption of Purchase Contracts.

                  Any or all of the Purchase Contracts may be redeemed at the
option of the Corporation, or from time to time in part, on any Interest Payment
Date on or after February 28, 2007, at a redemption price equal to $1.00 per
Purchase Contract, provided that no redemption shall result in there being more
than zero but fewer than 50,000 Unsettled Purchase Contracts remaining
Outstanding after such redemption, or in accordance with the next succeeding
paragraph, at any other time when the Debentures are redeemed.

                  In the event that MS plc shall redeem a Debenture constituting
part of a Capital Unit pursuant to the provisions of the Indenture, the
Corporation shall redeem the Purchase Contract constituting part of the same
Capital Unit on the redemption date of such related Debenture. In the event that
MS plc shall redeem all Debentures constituting part of


<PAGE>

                                       53

Capital Units pursuant to a Tax Redemption, the Corporation shall redeem all
Purchase Contracts then Outstanding on the redemption date of the Debentures.

Section 1002.     Notice of Redemption; Partial Redemptions.

                  The Corporation or, upon Issuer Request by the Corporation,
the Agent in the name and at the expense of the Corporation, shall give notice
of redemption to the Holders of Purchase Contracts in the manner and to the
extent provided in Section 1306, at least 30 days and not more than 60 days
prior to the date fixed for redemption. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the Holder receives the notice. Failure to give notice by mail, or any
defect in the notice to the Holder of any Purchase Contract, shall not affect
the validity of the proceedings for the redemption of any other Purchase
Contract.

                  The notice of redemption to each such Holder shall specify the
number of Purchase Contracts held by such Holder to be redeemed, the date fixed
for redemption, the redemption price, the place or places of payment and that
payment will be made upon presentation and surrender of Capital Unit
Certificates with respect to such Purchase Contracts evidenced by Capital Unit
Certificates.

                  The Corporation's obligation to provide funds for redemption
shall be deemed fulfilled if, on or before 12:00 noon New York City time on the
redemption date specified in the notice of redemption given as provided in this
Section, the Corporation shall deposit with the Agent or with one or more paying
agents an amount of money sufficient to redeem on the redemption date all the
Purchase Contracts called for redemption at the appropriate redemption price,
together with irrevocable instructions and authorization that such funds be
applied to the redemption of the Purchase Contracts called for redemption upon
surrender of Capital Unit Certificates representing such Purchase Contracts,
properly endorsed and assigned for transfer, in accordance with this Article.

                  The Corporation will deliver to the Agent at least 15 days
prior to the mailing of the notice of redemption an Officer's Certificate
stating the aggregate number of Purchase Contracts to be redeemed on such date
and that the Corporation has complied with the provisions of Section 1001.

                  If fewer than all the Purchase Contracts are to be redeemed,
the Agent, at least 15 days prior to the mailing of the redemption notice, shall
select the Purchase Contracts to be redeemed on a pro rata basis. Purchase
Contracts may be redeemed in multiples equal to the minimum authorized
denomination for Purchase Contracts or any multiple thereof. Appropriate
adjustment shall be made to prevent the fractional redemption

<PAGE>

                                       54

of Purchase Contracts, such that Purchase Contracts are redeemed only in whole
and not in part.

                  The Agent shall promptly notify the Corporation in writing of
the Purchase Contracts so selected for redemption.

Section 1003.     Payment of Purchase Contracts Called for Redemption.

                  If notice of redemption has been given as above provided, (i)
the Purchase Contracts specified in such notice shall become due and payable on
the date and at the place stated in such notice at the applicable redemption
price, and (ii) on and after the date fixed for redemption (unless the
Corporation shall default in the payment of such Purchase Contracts at the
redemption price) such Purchase Contracts shall cease from and after the date
fixed for redemption to be entitled to any benefit under this Agreement, the
Holders thereof shall have no right or obligation in respect of such Purchase
Contracts except the right to receive the redemption price thereof and the
Purchase Contracts shall terminate and shall no longer be deemed to be
Outstanding.

                  On presentation and surrender of Capital Unit Certificates
representing such Purchase Contracts, properly endorsed and assigned for
transfer, at a place of payment specified in said notice, said Purchase
Contracts shall be paid and redeemed by the Corporation at the applicable
redemption price. Following such redemption, the Capital Unit Certificates
evidencing such Closed Purchase Contracts shall be cancelled in accordance with
Section 308 or the Global Purchase Contract and Global Debenture shall be
endorsed to reflect the decrease in the number of Book-Entry Capital Units
evidenced thereby as a result of such redemption in accordance with Section 1109
(and shall be deemed to be cancelled with respect to the Purchase Contracts no
longer evidenced by such Global Purchase Contract as a result of such
redemption). In the case of (i) Definitive Capital Units, certificates
evidencing any Outstanding Debentures relating to such redeemed Purchase
Contracts shall be executed, authenticated and delivered in accordance with the
terms of the Indenture or (ii) Book-Entry Capital Units, if a Global Debenture
not constituting part of a Book-Entry Capital Unit has not previously been
issued by MS plc, a second Global Debenture evidencing any Outstanding
Debentures relating to such redeemed Purchase Contracts shall be executed,
authenticated and delivered in accordance with the Indenture. If a second Global
Debenture referred to in clause (ii) of the immediately preceding sentence has
already been issued to the Book-Entry Unit Depositary, the Book-Entry Unit
Depositary shall note thereon an appropriate increase in the number of
Debentures represented by such Global Debenture.

                  Any interest accrued on funds deposited with the Agent or any
Paying Agent in connection with this Article Ten shall be paid to the
Corporation from time to time and the Holders of Purchase Contracts (whether or
not such Purchase Contracts are to be redeemed with such funds) shall have no
claim to any such interest. Any funds deposited and unclaimed at the end of two
years from any redemption date shall be repaid or released to the Corporation,
after which the Holder(s) of Purchase Contracts so called for redemption shall
look only to the Corporation for payment of the redemption price, without any
interest thereon.

Section 1004.     Exclusion of Certain Purchase Contracts
                  from Eligibility for Selection for Redemption.

                  Purchase Contracts shall be excluded from eligibility for
selection for a partial redemption if they are identified by registration and
certificate number in an Officer's Certificate delivered by the Corporation to
the Agent at least 10 days prior to the date of the mailing of a notice of
redemption as being owned of record and beneficially by, and not pledged or
hypothecated by (a) the Corporation or (b) an Affiliate of the Corporation.
Purchase Contracts shall also be excluded from eligibility for selection for a
partial redemption if they are the subject of an Acceleration Notice.

                  Contract and Global Debenture.

                  The Book-Entry Unit Depositary hereby accepts custody of the
Global Purchase Contract and any Global Debenture from the Agent and the Trustee
and shall act as Book-Entry Unit Depositary in accordance with the terms of this
Agreement. The Book-Entry Unit Depositary shall hold the Global Purchase
Contract and Global Debentures at its Corporate Trust Office in the Borough of
Manhattan or at such place or places as it shall determine with the consent of
MS plc and the Corporation and shall issue the Book-Entry Capital Units in
accordance with the Letter of Representations.

Section 1102.     Book-Entry System.

                  (a) Upon acceptance by DTC of Book-Entry Capital Units for
            entry into its book-entry settlement system in accordance with the
            terms of the Letter of Representations, interests in Book-Entry
            Capital Units will be traded through DTC's

            book-entry system, and ownership of beneficial interests in such
            Book-Entry Capital Units shall be shown in, and the transfer of such
            ownership shall be effected only through, records maintained by (i)
            DTC or its successors or (ii) institutions that have accounts with
            DTC or its successors. Interests in the Book-Entry Capital Units
            shall be transferable only as units representing whole Capital
            Units.

                  (b) Certificateless depositary interests in Book-Entry Capital
            Units or a second Global Debenture issued in accordance with Section
            405 or Section 1003 shall be issuable only to DTC, its nominee or
            successors of DTC and its nominee. No owner of beneficial interests
            in such Book-Entry Capital Units shall be entitled to receive a
            Purchase Contract or a Debenture, as the case may be, on account of
            such beneficial interest, and such beneficial owner's interest
            therein shall be shown only in accordance with the procedures of DTC
            as set forth in the Letter of Representations.

Section 1103.     Transfer of Interests in Book-Entry
                  Capital Units and Global Debentures.

                  The Corporation and MS plc appoint the Book-Entry Unit
Depositary as their agent to maintain at its Corporate Trust Office a register
(the "Book-Entry Unit Register") in which the Book-Entry Unit Depositary shall
(i) record the right of the Holder of Book-Entry Capital Units to receive
payment of principal and interest on the Global Debenture and (ii) record the
registration and transfer of interests in the Global Debenture and Global
Purchase Contract. Interests in such Global Debenture and Global Purchase
Contract relating to the Book-Entry Capital Units cannot be transferred unless
such transfer is recorded on the Book-Entry Unit Register. MS plc also appoints
the Book-Entry Unit Depositary as its agent to maintain at its Corporate Trust
Office a register (the "Second Global Debenture Register") in which, if a second
Global Debenture representing Outstanding Debentures that are not part of
Capital Units is issued pursuant to Section 405 or Section 1003, the Book-Entry
Unit Depositary shall (i) record the right of the Depositary to receive payment
of principal and interest on such second Global Debenture and (ii) record the
registration and transfer of interests in such second Global Debenture.
Interests in such second Global Debenture cannot be transferred unless such
transfer is recorded on the Second Global Debenture Register.

                  The foregoing paragraph shall not (i) impose an obligation on
the Book-Entry Unit Depositary to record the interests in or transfers of
interests in Book-Entry Capital Units or the second Global Debenture held by
institutions that have accounts with DTC or its successors or Persons that may
hold interests in Book-Entry Capital Units or the second Global Debenture
through such institutions and (ii) restrict transfers of such interests held by
such institutions or persons. The person in whose name the Book-Entry Capital
Units are


<PAGE>

                                       57

registered on the Book-Entry Unit Register shall be the "Holder" of such
Book-Entry Capital Units for the purposes of this Agreement. So long as the
Global Debentures and the Global Purchase Contract are registered in the
Book-Entry Unit Register or the Second Global Debenture Register in the name of
DTC or its nominee, the Book-Entry Unit Depositary shall treat DTC as the
absolute owner thereof for all purposes whatsoever and shall not be bound or
affected by any notice to the contrary, other than an order of a court having
jurisdiction over the Book-Entry Unit Depositary.

Section 1104.     Issuance and Exchange of Definitive Capital
                  Units and Registered Definitive Debentures.

                  (a) Upon receipt by the Book-Entry Unit Depositary at its
            Corporate Trust Office of written instructions from the Holder of
            Book-Entry Capital Units requesting the issuance of Definitive
            Capital Units in respect of a portion of the Book-Entry Capital
            Units or the issuance of Registered Definitive Debentures in respect
            of a portion of a Global Debenture, the Book-Entry Unit Depositary
            shall request in accordance with Section 311 hereof or Section 2.8
            of the Indenture, as applicable, that Definitive Capital Units or
            Registered Definitive Debentures, as the case may be, be issued in
            the amounts and registered in the names specified in such request.

                  (b) The Book-Entry Unit Depositary shall promptly notify the
            Agent, with respect to Purchase Contracts, or the Trustee, with
            respect to Debentures, of any request by the Holder of Book-Entry
            Capital Units for the issuance of Definitive Capital Units or
            Registered Definitive Debentures. In connection with any request for
            the issuance of Registered Definitive Debentures or Definitive
            Capital Units as contemplated by this Section, the Book-Entry Unit
            Depositary shall promptly (i) reduce the Global Purchase Contract by
            the number of Definitive Capital Units to be countersigned, executed
            and delivered pursuant to such request, and (ii) reduce the
            aggregate principal amount of the Global Debenture by the principal
            amount of the Debentures to be represented by such Definitive
            Capital Units or the principal amount of the Registered Definitive
            Debentures to be issued pursuant to such request, as the case may
            be, and shall promptly notify the Agent of such reductions. Upon the
            issuance of Registered Definitive Debentures or Definitive Capital
            Units as set forth above, the Book-Entry Unit Depositary will make
            such notations in the Book-Entry Unit Register as will be necessary
            to reflect such reduction.

                  (c) If the Agent shall notify the Book-Entry Unit Depositary
            of any request by a Holder of Definitive Capital Units to transfer
            or exchange such Definitive Capital Units for interests in the
            Book-Entry Capital Units, the Book-Entry Unit Depositary shall
            promptly note the increase in the number of Purchase


<PAGE>

                                       58

            Contracts or aggregate principal amount of Debentures, as the case
            may be, constituting the Book-Entry Capital Units issued pursuant to
            such request on the Global Purchase Contract and the Global
            Debenture, respectively. If the Trustee shall notify the Book-Entry
            Unit Depositary of any request by a holder of Registered Definitive
            Debentures to transfer or exchange such Registered Definitive
            Debentures for interests in the second Global Debenture, the
            Book-Entry Unit Depositary shall promptly note the increase in the
            principal amount of such second Global Debenture. In order to
            evidence the issuance of the Book-Entry Capital Units as set forth
            above, the Book-Entry Unit Depositary shall make such notations in
            the Book-Entry Unit Register as will be necessary to reflect such
            increase.

                  (d) Requests by the Holder for the issuance of Registered
            Definitive Debentures and Definitive Capital Units and requests by
            Holders of Definitive Capital Units for interests in the Book-Entry
            Capital Units may be made only with respect to whole Capital Units
            and interests in the Global Purchase Contract may only be
            transferred as part of whole Capital Units.

                  Notwithstanding the foregoing, this Section 1104 shall be
subject to the provisions of the last paragraph of Section 305.

Section 1105.     Transfer of the Global
                  Purchase Contract and Global Debenture.

                  The Book-Entry Unit Depositary shall hold the Global Purchase
Contract and the Global Debentures in custody for the benefit of the Depositary.
The Book-Entry Unit Depositary shall not transfer or lend the Global Purchase
Contract or the Global Debentures or any interest therein except that the
Book-Entry Unit Depositary may transfer the Global Purchase Contract and the
Global Debentures to a successor Book-Entry Unit Depositary with the consent of
MS plc and the Corporation. Notwithstanding the foregoing, the Depositary may
not under any circumstances request the Book-Entry Unit Depositary to surrender
or deliver any Global Debenture or Global Purchase Contract to the Depositary.
If (i) the Book-Entry Unit Depositary notifies MS plc, the Corporation, the
Agent and the Trustee under Section 1208 hereof that it desires to resign as
Book-Entry Unit Depositary and no successor Book-Entry Unit Depositary has been
appointed by MS plc and the Corporation within 90 days of such notification,
(ii) if an Event of Default with respect to the Debentures occurs or (iii) if
DTC notifies MS plc and the Corporation that it is unwilling or unable to
continue as Depositary with respect to the certificateless depositary interests
representing Book-Entry Capital Units or if at any time it ceases to be a
clearing agency under the Exchange Act and a successor Depositary registered as
a clearing agency under the Exchange Act is not appointed by MS plc and the
Corporation within 90 days,


<PAGE>

                                       59

then the Book-Entry Unit Depositary will promptly notify the Agent and the
Trustee and request the Agent and the Trustee, as applicable, to issue
Registered Definitive Debentures and Definitive Capital Units in such names and
denominations as the Holder shall specify in accordance with Section 2.8 of the
Indenture or Section 311 of this Agreement, as the case may be, and the
Book-Entry Unit Depositary agrees that in such event it will promptly surrender
the Global Purchase Contract to the Agent and the Global Debentures to the
Trustee in connection with such exchange and that such Global Purchase Contract
and Global Debentures will be cancelled upon issuance of such Definitive Capital
Units and Registered Definitive Debentures, respectively.

Section 1106.     Mutilated, Destroyed, Lost and Stolen Global
                  Debentures and Global Purchase Contracts.

                  If any mutilated Global Debenture or Global Purchase Contract
is surrendered to the Trustee or the Agent, MS plc (with respect to the Global
Debenture) or the Corporation (with respect to the Global Purchase Contracts)
shall execute and deliver to the Trustee or the Agent, as the case may be, and
the Trustee or the Agent, as the case may be, shall authenticate, countersign,
execute and deliver, as appropriate, in exchange therefor a new Global Debenture
or Global Purchase Contract of like tenor, evidencing the same number of
Debentures or Purchase Contracts and bearing a number not contemporaneously
outstanding.

                  If there shall be delivered to MS plc, the Corporation, the
Trustee and the Agent (i) evidence to their satisfaction of the destruction,
loss or theft of any Global Debenture or Global Purchase Contract and (ii) such
security or indemnity as may be required by them to hold each of them and any
agent of any of them harmless, then, in the absence of notice to MS plc, the
Corporation, the Trustee or the Agent that such Global Debenture or Global
Purchase Contract has been acquired by a bona fide purchaser, MS plc (with
respect to the Global Debenture) and the Corporation (with respect to the Global
Purchase Contract) shall execute and deliver to the Trustee or the Agent, as the
case may be, and the Trustee (in accordance with the provisions of the
Indenture) and the Agent shall authenticate, countersign, execute and deliver to
the Book-Entry Unit Depositary, as appropriate, in lieu of any such destroyed,
lost or stolen Global Debenture or Global Purchase Contract, as the case may be,
a new Global Debenture or Global Purchase Contract, as the case may be, of like
tenor, evidencing the same number of Debentures or Purchase Contracts and
bearing a number not contemporaneously outstanding.

                  Notwithstanding the foregoing, MS plc (with respect to the
Global Debentures) and the Corporation (with respect to the Global Purchase
Contracts) shall not be obligated to execute and deliver to the Trustee or the
Agent, and neither the Trustee

                                       60

under the Indenture nor the Agent shall be obligated to authenticate,
countersign and execute or deliver to the Book-Entry Unit Depositary, a new
Global Debenture or Global Purchase Contract (i) during the period beginning any
time on or after the opening of business 15 days before the day of mailing of a
notice of redemption or acceleration of the Purchase Contracts evidenced by such
Global Purchase Contract and ending at the close of business on the day of the
giving of such notice, (ii) that evidences Purchase Contracts selected or called
for redemption or acceleration or (iii) at any given date, if such date is on or
after the Purchase Date or date of redemption, as applicable, with respect to
the Purchase Contracts evidenced by such Global Purchase Contract, except with
respect to any Debentures and Purchase Contracts constituting part of Book-Entry
Capital Units that remain or will remain Outstanding following such Purchase
Date or date of redemption. Upon satisfaction of the applicable conditions
specified in clauses (i) and (ii) of the preceding paragraph, the Agent shall
deliver or cause to be delivered (i) in respect of Purchase Contracts
constituting a part of the Book-Entry Capital Units that are selected or called
for redemption, the redemption price of such Purchase Contracts or (ii) in
respect of Purchase Contracts constituting a part of the Book-Entry Capital
Units with respect to which a Cash Settlement or Debenture Settlement has taken
place, (x) the Depositary Shares issuable with respect to such Purchase
Contracts (and, in the case of an effective Cash Settlement, the related
Debentures) or (y) if a Termination Event shall have occurred or a Purchase
Contract Default has occurred by virtue of the Corporation's having failed to
issue the Preferred Stock against tender by the Agent of payment for the
Depositary Shares evidencing such Preferred Stock, the payment, if any, received
by the Agent in respect of the Purchase Price of such Purchase Contracts or in
respect of principal with respect to the related Debentures received by the
Agent, as the case may be, in each case as provided in Section 405, Section 903
and Article Ten, as applicable.

                  Upon the issuance of any new Global Debentures or Global
Purchase Contracts under this Section, MS plc, the Corporation and the Agent may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Agent) connected therewith.

                  Every new Global Debenture or Global Purchase Contract issued
pursuant to this Section in lieu of any destroyed, lost or stolen Global
Debenture or Global Purchase Contract shall constitute an original additional
contractual obligation of MS plc (with respect to the Global Debentures) and the
Corporation (with respect to the Guarantee and the Global Purchase Contracts)
and of the Holder (with respect to the Book-Entry Capital Units evidenced
thereby), whether or not the destroyed, lost or stolen Global Debenture or
Global Purchase Contract shall be at any time enforceable by anyone, and shall
be entitled to all the

                                       61

benefits of this Agreement equally and proportionately with any and all other
Global Debentures or Global Purchase Contracts delivered hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Global
Debentures or Global Purchase Contracts.

Section 1107.     Cancellation.

                  All Global Purchase Contracts and Global Debentures
surrendered for payment, and all Global Purchase Contracts and Global Debentures
surrendered for redemption of the Debentures or the Purchase Contracts evidenced
thereby, termination of the Purchase Contracts evidenced thereby, delivery of
Depositary Shares or registration of transfer or exchange shall, if surrendered
to any Person other than the Agent or the Trustee, be delivered to the Agent or
the Trustee, as appropriate, and, if not already cancelled, the Global Purchase
Contracts and Global Debentures shall be promptly cancelled by the Agent or the
Trustee. MS plc or the Corporation may at any time deliver to the Agent or the
Trustee for cancellation any Global Purchase Contracts and Global Debentures
previously authenticated, countersigned, executed and delivered hereunder and
under the Indenture which MS plc or the Corporation may have acquired in any
manner whatsoever, and all Global Purchase Contracts and Global Debentures so
delivered shall, upon Issuer Order of each of MS plc and the Corporation, be
promptly cancelled by the Agent or the Trustee. No Global Purchase Contracts and
Global Debentures shall be authenticated, countersigned and executed in lieu of
or in exchange for any Global Purchase Contracts and Global Debentures cancelled
as provided in this Section, except as permitted by this Agreement or the
Indenture. All cancelled Global Purchase Contracts and Global Debentures held by
the Agent or the Trustee shall be disposed of in accordance with their customary
procedures and a certificate of their disposition shall be delivered by the
Agent or the Trustee to MS plc and the Corporation, unless by Issuer Order
either MS plc or the Corporation shall direct that cancelled Global Purchase
Contracts and Global Debentures be returned to it.

                  If MS plc, the Corporation or any Affiliate of MS plc or the
Corporation shall acquire any Global Purchase Contracts or Global Debentures,
such acquisition shall not operate as a cancellation of such Global Purchase
Contracts or Global Debentures unless and until such Global Purchase Contracts
or Global Debentures are delivered to the Agent or the Trustee cancelled or for
cancellation.

Section 1108.     Payments in Respect of Book-Entry
                  Capital Units and Global Debenture.

                  (a) Whenever the Book-Entry Unit Depositary shall receive from
            the Agent or the Trustee (or other paying agent under the Indenture)
            any payment on the Book-Entry Capital Units or second Global
            Debenture, such payments shall be forwarded promptly upon receipt of
            such amounts in its capacity as collecting agent with respect to the
            Book-Entry Capital Units or the second Global Debenture from the
            Agent or the Trustee (or other paying agent under the Indenture), to
            the Holder on the payment date for such Book-Entry Capital Units or
            Global Debenture. So long as DTC is the Holder, such payments shall
            be made in accordance with the Letter of Representations.

                  (b) The Book-Entry Unit Depositary will forward to MS plc or
            the Corporation or their agents such information from its records as
            MS plc or the Corporation may reasonably request to enable MS plc,
            the Corporation or their agents to file necessary reports with
            governmental agencies, and the Book-Entry Unit Depositary, MS plc,
            the Corporation or their agents may (but shall not be required to)
            file any such reports necessary to obtain benefits under any
            applicable tax treaties for the Holder of, or beneficial owners of
            interests in, the Book-Entry Capital Units.

Section 1109.     Redemption or Settlement.

                  (a) In the event that MS plc exercises any right of redemption
            in respect of any Debentures constituting a part of a Global
            Debenture, the Book-Entry Unit Depositary shall promptly upon
            receipt of the redemption price reduce the principal amount of such
            Global Debenture representing the principal amount of the Debentures
            so redeemed. The redemption price in connection with the redemption
            of a portion of such Global Debenture shall be equal to the amount
            received by the Book-Entry Unit Depositary in respect of the
            aggregate principal amount of the Debentures so redeemed.

                  (b) In the event that the Corporation exercises any right of
            redemption in respect of any Purchase Contracts constituting a part
            of the Global Purchase Contract, the Book-Entry Unit Depositary
            shall promptly upon receipt of the redemption price note the
            reduction in the number of Purchase Contracts representing a portion
            of the Global Purchase Contract that represents the portion of the
            Purchase Contracts so redeemed. The redemption price in connection
            with the redemption of a portion of the Global Purchase Contract
            shall be equal to the amount received by


<PAGE>

                                       63

            the Book-Entry Unit Depositary in respect of the number of Purchase
            Contracts so redeemed.

                  (c) In connection with the settlement of any Purchase
            Contracts constituting a part of the Global Purchase Contract
            pursuant to Section 404, the Book-Entry Unit Depositary, shall
            promptly note (i) in the event of a Debenture Settlement, on the
            Global Purchase Contract, the decrease in the number of Outstanding
            Purchase Contracts corresponding to the number of such settled
            Purchase Contracts and on the Global Debenture the decrease in the
            related Debentures and (ii) in the event of a Cash Settlement, (x)
            on the Global Purchase Contract the decrease in the number of
            Outstanding Purchase Contracts corresponding to the number of such
            settled Purchase Contracts, and (y) on the second Global Debenture
            representing Debentures still Outstanding that are not part of
            Capital Units, the increase in the aggregate principal amount of the
            Debentures that remain Outstanding following the acceleration
            thereof. If a second Global Debenture referred to in clause (y) of
            the immediately preceding sentence has not previously been issued by
            MS plc, MS plc shall execute and the Trustee shall authenticate and
            deliver a second Global Debenture representing the aggregate
            principal amount of Debentures still Outstanding following
            settlement of the related Purchase Contracts and that are not part
            of Capital Units.

Section 1110.     Record Date.

                  Whenever any payment is to be made in respect of the Global
Purchase Contract or a Global Debenture, or the Book-Entry Unit Depositary shall
receive notice of any action to be taken by the Holder of the Book-Entry Capital
Units or a Global Debenture, or whenever the Book-Entry Unit Depositary
otherwise deems it appropriate in respect of any other matter, the Book-Entry
Unit Depositary shall fix a record date for the determination of the Holder of
the applicable Global Debenture or Book-Entry Capital Units who shall be
entitled to receive such payment or to take any such action or to act in respect
of any such matter. Subject to the provisions of this Agreement, only the Holder
of a Global Debenture or Book-Entry Capital Units who is registered on the
Book-Entry Unit Register at the close of business on such record date shall be
entitled to receive any such payment, to give instructions as to such action or
to act in respect of any such matter.

containing (a) such information as is contained in such notice, (b) a statement
that the Holder at the close of business on a specified record date (established
in accordance with Section 1110) will be entitled, subject to the provisions of
or governing the Book-Entry Capital Units or Global Debenture, as the case may
be, to instruct the Book-Entry Unit Depositary as to the consent, waiver or
other action, if any, pertaining to the Book-Entry Capital Units or Global
Debenture, as the case may be, and (c) a statement as to the manner in which
such instructions may be given. Upon the written request of the Holder, received
on or before the date established by the Book-Entry Unit Depositary for such
purpose, the Book-Entry Unit Depositary shall endeavor insofar as practicable
and permitted under the provisions of or governing the Book-Entry Capital Units
or Global Debenture, as the case may be, to take such action regarding the
requested consent, waiver or other action in respect of the Book-Entry Capital
Units or Global Debenture, as the case may be, in accordance with any
instructions set forth in such request. The Book-Entry Unit Depositary shall not
itself exercise any discretion in the granting of consents or waivers or the
taking of any other action in respect of the Book-Entry Capital Units or Global
Debenture.

Section 1112.     Changes Affecting the Global
                  Purchase Contract or Global Debenture.

Global Debenture, or upon any recapitalization, reorganization, merger or
consolidation or sale of assets affecting MS plc or the Corporation or to which
either is a party, any securities that shall be received by the Book-Entry Unit
Depositary in exchange for or in conversion of or in respect of the Global
Purchase Contract or Global Debenture shall be treated as a new Global Purchase
Contract or Global Debenture, as the case may be, under this Agreement and any
corresponding Book-Entry Capital Units shall thenceforth represent such new
securities so received.

Section 1113.     Surrender of Global Purchase
                  Contract and Global Debenture.

                  In the event of the redemption in full of all the Purchase
Contracts represented by the Global Purchase Contract or of all the Debentures
represented by the Global Debenture, then the applicable Global Debenture and
Global Purchase Contract shall become void and the Book-Entry Unit Depositary
shall surrender such Global Debenture and Global Purchase Contract to the Agent
and the Trustee, as applicable, for cancellation.

                  Provisions of This Agreement.

                  The Book-Entry Unit Depositary will at any time at the
direction of the Corporation or MS plc, as applicable, terminate the Book-Entry
Capital Unit provisions of this Agreement by mailing a notice of such

that the Trustee and the Agent, as applicable, authenticate, countersign,
execute and deliver Definitive Capital Units in replacement of Book-Entry
Capital Units to such Persons and in the amounts as specified by the Depositary.
Upon the authentication, countersignature, execution and delivery of such
Definitive Capital Units, the Book-Entry Capital Unit provisions of this
Agreement will terminate. The Book-Entry Capital Unit provisions of this
Agreement may also be terminated upon the resignation of the Book-Entry Unit
Depositary if no successor Book-Entry Unit Depositary is appointed with 90 days
in accordance with Section 311 and Section 1105.

            wilful misconduct, except that

                  (1) the duties and obligations of the Book-Entry Unit
            Depositary with respect to the Book-Entry Capital Units, Global
            Debentures and the Global Purchase Contract shall be determined
            solely by the express provisions of this Agreement and

            the Book-Entry Unit Depositary shall not be liable except for the
            performance of such duties and obligations as are specifically set
            forth in this Agreement, and no implied covenants or obligations
            shall be read into this Agreement against the Book-Entry Unit

            Unit Depositary may conclusively rely, as to the truth of the
            statements and the correctness of the opinions expressed therein,
            upon any statements, certificates or opinions furnished to the
            Book-Entry Unit Depositary and conforming to the requirements of
            this Agreement, but in the case of any such statements, certificates
            or opinions that by any provision hereof are specifically required
            to be furnished to the Book-Entry Unit Depositary, the Book-Entry
            Unit Depositary shall be under a duty to examine the same to
            determine whether or not they conform to the requirements of this
            Agreement.

                  (c) The Book-Entry Unit Depositary shall not be liable for any
            error of judgment made in good faith by a Responsible Officer of the

            Capital Units relating to the time, method and place of conducting
            any proceeding for any remedy available to the Book-Entry Unit

            Unit Depositary, under this Agreement.

                  (e) No provision of this Agreement shall require the
            Book-Entry Unit Depositary to expend or risk its own funds or
            otherwise incur any financial liability in the performance of any of
            its duties hereunder, or in the exercise of any of its rights or
            powers, if it shall have reasonable grounds for believing that
            repayment of such funds or adequate indemnity against such risk or
            liability is not reasonably assured to it.

                  (f) Whether or not therein expressly so provided, every
            provision of this Agreement relating to the conduct or affecting the
            liability of or affording protection to the Book-Entry Unit
            Depositary shall be subject to the provisions of this Section.

            this Agreement at the request, order or direction of any of the
            Holders pursuant to this Agreement, unless such Holders shall have
            offered to the Book-Entry Unit Depositary reasonable security or
            indemnity against the costs, expenses and liabilities that might be
            incurred by it in compliance with such request or direction,
            provided that such request, order or direction shall not expose the
            Book-Entry Unit Depositary to personal liability; and

                  (g) the Book-Entry Unit Depositary shall not be liable for any
            action taken or omitted by it in good faith and believed by it to be
            authorized or within the discretion, rights or powers conferred upon
            it by this Agreement.

Section 1204.     Not Responsible for Recitals or Issuance of Capital Units.

                  The recitals contained herein, in the Indenture and in the
Capital Units, except the Trustee's and the Agent's certificates of
authentication, shall be taken as the statements of MS plc or the Corporation,
as the case may be, and the Book-Entry Unit Depositary assumes no responsibility
for their correctness. The Book-Entry Unit Depositary makes no representations
as to the validity or sufficiency of this Agreement or of the Capital Units. The
Book-Entry Unit Depositary shall not be accountable for the use or application
by MS plc or the Corporation of the proceeds with respect to Capital Units.

Section 1205.     Money Held in Trust.

                  Money held by the Book-Entry Unit Depositary in trust
hereunder need not be segregated from other funds held by the Book-Entry Unit
Depositary, except to the extent required by law. The Book-Entry Unit Depositary
shall be under no obligation to invest or pay interest on any money received by
it hereunder, except as otherwise agreed with MS plc and the Corporation. Any
interest accrued on funds deposited with the Book-Entry Unit Depositary under
this Agreement shall be paid to MS plc and the Corporation from time to time and
the Holder of Book-Entry Capital Units (whether or not any Purchase Contracts
are to be redeemed with such funds) shall have no claim to any such interest.

Section 1206.     Compensation and Reimbursement.

                  MS plc and the Corporation agree:

                  (a) to pay to the Book-Entry Unit Depositary from time to time
            reasonable compensation for all services rendered by it hereunder
            (which compensation shall not be limited by any provision of law
            with regard to the compensation of a trustee of an express trust);

                  (b) except as otherwise expressly provided herein, to
            reimburse the Book-Entry Unit Depositary and any predecessor
            Book-Entry Unit Depositary upon its request for all reasonable
            expenses, disbursements and advances incurred or made by the
            Book-Entry Unit Depositary in accordance with any provision of this
            Agreement (including the reasonable compensation and the expenses
            and disbursements of its agents and counsel), except any such
            expense, disbursement or advance as may be attributable to its
            negligence or bad faith; and

                  (c) to indemnify the Book-Entry Unit Depositary and any
            predecessor Book-Entry Unit Depositary for, and to hold it harmless
            against, any loss, liability or expense incurred without negligence
            or bad faith on its part, arising out of or in connection with the
            acceptance or administration of this Agreement and its duties
            hereunder, including the costs and expenses of defending itself
            against or investigating any claim of liability in connection with
            the exercise or performance of any of its powers or duties
            hereunder.

                  The obligations of MS plc and the Corporation under this
Section to compensate and indemnify the Book-Entry Unit Depositary and any
predecessor Book-Entry Unit Depositary and to pay or reimburse the Book-Entry
Unit Depositary and any predecessor Book-Entry Unit Depositary for expenses,
disbursements and advances shall


<PAGE>

                                       70

constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Agreement. Such additional indebtedness shall be a senior
claim to that of the Capital Units upon all property and funds held or collected
by the Book-Entry Unit Depositary as such, except funds held in trust for the
benefit of the Holders of Capital Units, and the Capital Units are hereby
subordinated to such senior claim.

Section 1207.     Book-Entry Unit
                  Depositary Required; Eligibility.

                  At all times when there is a Book-Entry Unit Depositary
hereunder, such Book-Entry Unit Depositary shall be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, having, together with its parent, a combined
capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal, State or District of Columbia authority, willing to act
on reasonable terms. Such corporation shall have its principal place of business
in the Borough of Manhattan, The City of New York, if there be such a
corporation in such location willing to act upon reasonable and customary terms
and conditions. If such corporation, or its parent, publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. The Book-Entry Unit Depositary hereunder shall at all
times be the Agent hereunder and the Trustee under the Indenture, subject to
receipt of an Opinion of Counsel that the same Person is precluded by law from
acting in such capacities. If at any time the Book-Entry Unit Depositary shall
cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

Section 1208.     Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Book-Entry Unit
            Depositary and no appointment of a successor Book-Entry Unit
            Depositary pursuant to this Article shall become effective until (i)
            the acceptance of appointment by the successor Book-Entry Unit
            Depositary in accordance with the applicable requirements of Section
            1209 or (ii) the issuance of Capital Unit Certificates in accordance
            with Section 311.

                  (b) The Book-Entry Unit Depositary may resign with respect to
            the Capital Units by giving written notice thereof to MS plc and the
            Corporation and the Holders, in accordance with Section 1305 and
            Section 1306, 60 days prior to the effective date of such
            resignation. The Book-Entry Unit Depositary may be removed


<PAGE>

                                       71

            at any time upon 60 days' notice by the filing with it of an
            instrument in writing signed on behalf of MS plc and the Corporation
            and specifying such removal and the date when it is intended to
            become effective. If the instrument of acceptance by a successor
            Book-Entry Unit Depositary required by Section 1209 shall not have
            been delivered to the Book-Entry Unit Depositary within 30 days
            after the giving of such notice of resignation, the resigning
            Book-Entry Unit Depositary may petition any court of competent
            jurisdiction for the appointment of a successor Book-Entry Unit
            Depositary.

                  (c) If at any time

                  (1) the Book-Entry Unit Depositary shall cease to be eligible
            under Section 1207, or shall cease to be eligible as Agent hereunder
            or as Trustee under the Indenture, and shall fail to resign after
            written request therefor by MS plc, the Corporation or by any
            Holder, or

                  (2) the Book-Entry Unit Depositary shall become incapable of
            acting with respect to the Book-Entry Capital Units or shall be
            adjudged a bankrupt or insolvent, or a receiver or liquidator of the
            Book-Entry Unit Depositary or of its property shall be appointed or
            any public officer shall take charge or control of the Book-Entry
            Unit Depositary or of its property or affairs for the purpose of
            rehabilitation, conservation or liquidation, then, in any such case,
            (i) MS plc or the Corporation, by Board Resolution, may remove the
            Book-Entry Unit Depositary and appoint a successor Book-Entry Unit
            Depositary, or (ii) any Holder who has been a bona fide Holder of a
            Book-Entry Capital Unit for at least six months may, on behalf of
            himself and all others similarly situated, petition any court of
            competent jurisdiction for the removal of the Book-Entry Unit
            Depositary and the appointment of a successor Book-Entry Unit
            Depositary or Book-Entry Unit Depositaries, unless Capital Unit
            Certificates have been issued in accordance with Section 311. Such
            court may thereupon, after such notice, if any, as it may deem
            proper and prescribe, remove the Book-Entry Unit Depositary and
            appoint a successor Book-Entry Unit Depositary.

                  (d) If the Book-Entry Unit Depositary shall resign, be removed
            or become incapable of acting, or if a vacancy shall occur in the
            office of Book-Entry Unit Depositary for any cause, MS plc and the
            Corporation, by Board Resolution, shall promptly appoint a successor
            Book-Entry Unit Depositary (other than the Corporation or MS plc)
            and shall comply with the applicable requirements of Section 1209 or
            shall comply with Section 311. If no successor Book-Entry Unit
            Depositary with respect to the Capital Units shall have been so
            appointed by MS plc and the


<PAGE>

                                       72

            Corporation and accepted appointment in the manner required by
            Section 1209, any Holder who has been a bona fide Holder of a
            Capital Unit for at least six months may, on behalf of himself and
            all others similarly situated, petition any court of competent
            jurisdiction for the appointment of a successor Book-Entry Unit
            Depositary, unless Capital Unit Certificates have been issued in
            accordance with Section 311.

                  (e) MS plc and the Corporation shall give, or shall cause such
            successor Book-Entry Unit Depositary to give, notice of each
            resignation and each removal of the Book-Entry Unit Depositary and
            each appointment of a successor Book-Entry Unit Depositary to all
            Holders of Capital Units in accordance with Section 1306. Each
            notice shall include the name of the successor Book-Entry Unit
            Depositary and the address of its Corporate Trust Office.

Section 1209.     Acceptance of Appointment by Successor.

                  (a) In case of the appointment hereunder of a successor
Book-Entry Unit Depositary, every such successor Book-Entry Unit Depositary so
appointed shall execute, acknowledge and deliver to MS plc and the Corporation
and to the retiring Book-Entry Unit Depositary an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Book-Entry
Unit Depositary shall become effective and such successor Book-Entry Unit
Depositary, without any further act, deed or conveyance, shall become vested
with all the rights, powers, agencies and duties of the retiring Book-Entry Unit
Depositary, with like effect as if originally named as Book-Entry Unit
Depositary hereunder; but, on the request of MS plc, the Corporation or the
successor Book-Entry Unit Depositary, such retiring Book-Entry Unit Depositary
shall, upon payment of all amounts due and payable to it pursuant to Section
1206, execute and deliver an instrument transferring to such successor
Book-Entry Unit Depositary all the rights and powers of the retiring Book-Entry
Unit Depositary and shall duly assign, transfer and deliver to such successor
Book-Entry Unit Depositary all property and money held by such retiring
Book-Entry Unit Depositary hereunder. Any retiring Book-Entry Unit Depositary
shall, nonetheless, retain a prior claim upon all property or funds held or
collected by such Book-Entry Unit Depositary to secure any amounts then due it
pursuant to Section 1206.

                  (b) Upon request of any such successor Book-Entry Unit
Depositary, MS plc and the Corporation shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor Book-Entry
Unit Depositary all such rights, powers and agencies referred to in paragraph
(a) of this Section.


<PAGE>

                                       73

                  (c) No successor Book-Entry Unit Depositary shall accept its
appointment unless at the time of such acceptance such successor Book-Entry Unit
Depositary shall be eligible under this Article.

                  (d) Upon acceptance of appointment by any successor Book-Entry
Unit Depositary as provided in this Section, MS plc and the Corporation shall
give notice thereof to the Holder of Book-Entry Capital Units in accordance with
Section 1306. If the acceptance of appointment is substantially contemporaneous
with the resignation of the Book-Entry Unit Depositary, then the notice called
for by the preceding sentence may be combined with the notice called for by
Section 1208. If MS plc and the Corporation fail to give such notice within ten
days after acceptance of appointment by the successor Book-Entry Unit
Depositary, the successor Book-Entry Unit Depositary shall cause such notice to
be given at the expense of MS plc and the Corporation.

Section 1210.     Merger, Conversion,
                  Consolidation or Succession to Business.

                  Any corporation into which the Book-Entry Unit Depositary may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Book-Entry
Unit Depositary shall be a party, or any corporation succeeding to all or
substantially all the agency business of the Book-Entry Unit Depositary, shall
be the successor of the Book-Entry Unit Depositary hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, provided that such corporation shall be otherwise eligible under
this Article.

Section 1211.     Taxes.

                  If any tax or other governmental charge shall be required to
be deducted or withheld from any distribution in respect of the Global
Debentures or Global Purchase Contracts, MS plc and the Corporation shall pay or
cause to be paid such Additional Amounts as may be necessary in order that the
net amounts received by the Holder, after such deduction or withholding, shall
equal the net amounts that would otherwise be payable to the Holder in respect
of the Global Purchase Contract or the Global Debenture, as the case may be, in
the absence of any such deduction or withholding. In addition, in the event the
U.K. stamp duty reserve tax ("SDRT") is imposed on the Book-Entry Unit
Depositary or the holders of the Capital Units upon the issuance of the Capital
Units, MS plc will pay the Book-Entry Unit Depositary an amount equal to the
SDRT so imposed and the Book-Entry Unit Depositary shall be responsible for the
payment of the SDRT, but solely out of funds made available to it by MS plc. In
the event the SDRT is imposed on the holders of


<PAGE>

                                       74

the Capital Units or on the Book-Entry Unit Depositary as agent for holders of
the Capital Units upon the issuance of the Capital Units, the payment from MS
plc shall constitute a reduction of the purchase price paid by each such holder.

                                ARTICLE THIRTEEN

                            Miscellaneous Provisions

                  No recourse under or upon any obligation, covenant or
agreement contained in this Agreement, or in any Debenture or any Purchase
Contract, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, or against any past, present or future stockholder, officer,
attorney-in-fact or director, as such, of MS plc or the Corporation or of any
successor corporation of either of them, either directly or through MS plc or
the Corporation or any successor corporation of either of them, under any rule
of law, statute or constitutional provision or by the enforcement of any
assessment or penalty or by any legal or equitable proceeding or otherwise, all
such liability being expressly waived and released by the acceptance of the
Capital Units by the Holders thereof and as part of the consideration for the
issue thereof, provided that nothing in this Article shall impair the
obligations, covenants and agreements of MS plc and the Corporation contained in
this Agreement and in the Debentures and the Purchase Contracts.

Section 1302.     Compliance Certificates and Opinions.

                  Except as otherwise expressly provided by this Agreement, upon
any application or request by MS plc or the Corporation to the Agent to take any
action under any provision of this Agreement, MS plc or the Corporation, as
applicable, shall furnish to the Agent an Officer's Certificate stating that all
conditions precedent, if any, provided for in this Agreement relating to the
proposed action have been complied with and an Opinion of Counsel stating that,
in the opinion of such counsel, all such conditions precedent, if any, have been
complied with, except that in the case of any such application or request as to
which the furnishing of such documents is specifically required by any provision
of this Agreement relating to such particular application or request, no
additional certificate or opinion need be furnished.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Agreement shall include:


<PAGE>

                                       75


                  (1) a statement that each individual signing such certificate
            or opinion has read such covenant or condition and the definitions
            herein relating thereto;

                  (2) a brief statement as to the nature and scope of the
            examination or investigation upon which the statements or opinions
            contained in such certificate or opinion are based;

                  (3) a statement that, in the opinion of each such individual,
            he has made such examination or investigation as is necessary to
            enable him to express an informed opinion as to whether or not such
            covenant or condition has been complied with; and

                  (4) a statement as to whether, in the opinion of each such
            individual, such condition or covenant has been complied with.

Section 1303.     Form of Documents Delivered to Agent.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                  Any certificate, statement or opinion of an officer or counsel
of or for MS plc or the Corporation may be based, insofar as it relates to legal
matters, upon a certificate or opinion of, or representations by, counsel,
unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters
upon which his certificate, statement or opinion is based are erroneous. Any
such certificate, statement or opinion may be based, insofar as it relates to
factual matters, upon a certificate, statement or opinion of, or representations
by, an officer or officers of MS plc or the Corporation, as applicable, stating
that the information with respect to such factual matters is in the possession
of MS plc or the Corporation, as applicable, unless such counsel knows, or in
the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Agreement, they may, but need not, be consolidated
and form one instrument.

Section 1304.     Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Agreement to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Agent or the Book-Entry Unit Depositary, as applicable, and, where it is
hereby expressly required, to MS plc or the Corporation, as applicable. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Agreement and (subject to Section 601 and Section 1201) conclusive in favor of
the Agent, the Book-Entry Unit Depositary, MS plc and the Corporation, if made
in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved in any manner that the Agent or the
Book-Entry Unit Depositary, as applicable, deems sufficient.

proved by the Purchase Contract Register, with respect to the Purchase Contracts
constituting a part of such Definitive Capital Units, and the Definitive
Debenture Register, with respect to the Debentures constituting a part of such
Definitive Capital Units, and (ii) of Book-Entry Capital Units shall be proved
by the Book-Entry Unit Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Capital Unit Certificate shall
bind every future Holder of the same Capital Unit Certificate and the Holder of
every Capital Unit Certificate issued upon the registration of transfer thereof
or in exchange therefor or in lieu thereof with respect to anything done,
omitted or suffered to be done by the Agent, MS plc or the Corporation in
reliance thereon, whether or not notation of such action is made upon such
Capital Unit Certificate.

                  (e) MS plc and the Corporation may set a record date for
purposes of determining the identity of Holders of Capital Units entitled to
consent to any action by consent authorized or permitted hereby. Such record
date shall be the later of 30 days prior to the first solicitation of such
consent or the date of the most recent list of Holders of Capital Units
furnished to the Agent, pursuant hereto.

Section 1306.     Notice to Holders; Waiver.

                  Where this Agreement provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided or as provided in the Letter of Representations) if in
writing and mailed, first-class postage prepaid, to each Holder affected by such
event, (i) with respect to a Holder of a Definitive Capital Unit, at his address
as it appears in the Purchase Contract Register and the Definitive Debenture
Register, respectively, with respect to the Purchase Contract and the Debenture
and Guarantee constituting such Capital Unit, and (ii) with respect to a Holder
of a Book-Entry Capital Unit, to the Book-Entry Unit Depositary at the address
notified to the Agent, in each case not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Agreement provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Agent, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Agent
shall constitute a sufficient notification for every purpose hereunder.

Section 1307.     Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

                  All covenants and agreements in this Agreement, the Capital
Units, the Purchase Contracts and the Capital Unit Certificates by MS plc or by
the Corporation shall bind its successors and assigns, whether so expressed or
not.

Section 1309.     Separability Clause.

                  In case any provision in this Agreement or in the Capital
Units, Capital Unit Certificates or the Purchase Contracts shall be invalid,
illegal or unenforceable, the validity,


<PAGE>

                                       79

legality and enforceability of the remaining provisions hereof and thereof shall
not in any way be affected or impaired thereby.

express or implied, shall give to any Person, other than the parties hereto and
their successors hereunder, any benefits or any legal or equitable right, remedy
or claim under this Agreement. The Holders from time to time shall be parties to
this Agreement and shall be bound by all of the terms and conditions hereof and
of the Indenture, the Capital Units, the Debentures, the Guarantee and the
Purchase Contracts evidenced by the Capital Units, by their acceptance of
delivery of such Capital Units.

Section 1311.     Governing Law.

                  This Agreement, the Capital Units and the Purchase Contracts
shall be governed and construed in accordance with the laws of the State of New
York.

Section 1312.     Legal Holidays.

                  In any case where any Purchase Date shall not be a Business
Day, then (notwithstanding any other provisions of this Agreement or the
Purchase Contracts) the Purchase Contracts shall not be performed on such date,
but shall be performed on the next succeeding Business Day with the same force
and effect as if performed on such Purchase Date; provided that no interest or
other amounts shall accrue or be payable by the Corporation or any Holder for
the period from and after any such Purchase Date.

Section 1313.     Counterparts.

                  This Agreement may be executed in any number of counterparts
by the parties hereto on separate counterparts, each of which, when so executed
and delivered, shall be deemed an original, but all such counterparts shall
together constitute one and the same instrument.

Section 1314.     Inspection of Agreement.

office of such agent at 1585 Broadway, New York, New York 10036, Attention:
General Counsel, and written notice of said service to MS plc by the person
serving the same, addressed as provided in Section 1305, shall be deemed in
every respect effective service of process upon MS plc in any such legal action
or proceeding, and MS plc hereby submits (for the purposes of any such legal
action or proceeding) to the nonexclusive jurisdiction of any such court in
which any such legal action or proceeding is so instituted and waives, to the
extent it may effectively do so, any objection it may have now or hereafter to
the laying of the venue of any such legal action or proceeding. Such appointment
shall be irrevocable so long as the Holders of Capital Units shall have any
rights pursuant to the terms thereof or of this Agreement until the appointment

such successor. MS plc further agrees to take any and all action, including the

necessary to continue such designation and appointment of such agent or
successor for so long as Holders of Capital Units shall have any rights pursuant
to the terms thereof or of this Agreement. The Agent shall not be obligated and
shall have no responsibility with respect to any failure by MS plc to take any
such action.

TRUSTEE'S CERTIFICATE
OF AUTHENTICATION

This is one of the Securities referred to in the within-mentioned Indenture.

THE CHASE MANHATTAN BANK, as Trustee


By
  ------------------------
     Authorized Officer

                  Interest on this Debenture (as described below) will accrue
from the most recent Interest Payment Date to which interest has been paid or
duly provided for, or, if no interest has been paid or duly provided for, from
December 18, 1996, until the principal hereof has been paid or duly made
available for payment. The interest so payable on any Interest Payment Date will
be paid to the [bearer of]1[person in whose name]2 this Debenture (or one or
more predecessor Debentures) [is registered at the close of business on the
fifteenth day of the month in which such Interest Payment Date occurs (whether
or not a Business Day) (each such date a "Record Date")].2

                  Payment of the principal of this Debenture will be made upon
surrender of this Debenture at the office or agency of MS plc maintained for
that purpose in the Borough of Manhattan, The City of New York, or at such other
paying agency as MS plc may determine. Payment of the principal of and interest
on this Debenture will be made in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts.

                  This Debenture is one of the duly authorized debt securities
of MS plc (the "Securities" and, individually, a "Security") issued or to be
issued under and pursuant to a Subordinated Indenture dated as of November 15,
1993, (the "Indenture"), between MS plc, Morgan Stanley Group Inc., as Guarantor
(the "Guarantor" or the "Corporation") and The Chase Manhattan Bank (formerly
known as Chemical Bank), as Trustee (the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities of MS plc, the Guarantor,
the Trustee and Holders of the Securities and the terms upon which the
Securities are, and are to be, authenticated and delivered. The terms of the
Indenture are hereby incorporated by reference herein. The Securities may be
issued in one or more series, which different series may be issued in various
aggregate principal amounts, may mature at different times, may bear interest
(if any) at different rates, may be subject to different redemption or repayment
provisions (if any), may be subject to different sinking, purchase or analogous
funds (if any)

 -------- 
1    Applicable to Global Debenture only.

2    Applicable to Definitive Capital Unit only.


<PAGE>

                                        5

and may otherwise vary as provided in the Indenture. This security is one of a
series of Securities designated as the 8.03% Subordinated Debentures Due
February 28, 2017 of MS plc (the "Debentures"), in an aggregate principal amount
of U.S.$134,000,000.

                  The Debentures will not be subject to any sinking fund and
will be repayable at the option of the Holder prior to maturity upon the
election of the Holder to effect a Debenture Settlement (as defined in the
Capital Unit Agreement) upon the acceleration of the related Purchase Contracts
as set forth in the Capital Unit Agreement dated December 18, 1996 among MS plc,
the Corporation, The Chase Manhattan Bank and holders from time to time of
Capital Units (the "Capital Unit Agreement"). The Debentures will be redeemable,
at MS plc's option, in whole or in part, at any time on or after February 28,
2007 and prior to maturity, upon not less than 30 nor more than 60 days' prior
notice at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest to the date of redemption, if
redeemed during the twelve-month period beginning on February 28 of the years
indicated below:

            Year                                  Percentage

            2007  ...............................    102.677%
            2008  ...............................    102.141%
            2009  ...............................    101.606%
            2010 ................................    101.071%
            2011 ................................    100.535%

and thereafter at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to the date of redemption; provided,
however, that the Debentures shall be redeemable only (i) upon the redemption by
the Corporation of the related Purchase Contracts on or prior to the redemption
date for such Debentures or (ii) if the related Purchase Contracts have been
settled at least six months prior to the redemption date of such Debentures. In
addition, if a Holder properly effects a Cash Settlement (as defined in the
Capital Unit Agreement) with respect to a Purchase Contract, the related
Debenture may be redeemed at MS plc's option at the redemption price equal to
100% of the principal amount thereof, plus accrued and unpaid interest to the
redemption date, on any Interest Payment Date that is no earlier than six months
after the settlement of such Purchase Contract.

                  The Debentures may also be redeemed at any time, as a whole
but not in part, within 90 days of a Tax Event (as defined below) at the option
of MS plc, upon not less than 30 nor more than 60 days' notice, at a redemption
price equal to the Tax Event Prepayment Price (as defined below). Any such
redemption is referred to as a "Tax Redemption."

                  A "Tax Event" means either a U.S. Tax Event or a U.K. Tax
Event. A "U.S. Tax Event" means the receipt by the Corporation of an opinion of
counsel, rendered by a law firm having a recognized national tax practice, to
the effect that, as a result of any amendment to, change in or announced
prospective change in the laws (or any regulations thereunder) of the United
States ("U.S.") or any political subdivision or taxing authority thereof or
therein, or as a result of any official administrative pronouncement or judicial


<PAGE>

                                        6

decision interpreting or applying such laws or regulations, which amendment or
change is adopted or which proposed change, pronouncement or decision is
announced on or after December 13, 1996, there is more than an insubstantial
risk that interest payable by MS plc on the Debentures is not, or within 90 days
of the date of such opinion, will not be, deductible by MS plc, in whole or in
part, for U.S. federal income tax purposes.

                  A "U.K. Tax Event" means the determination by MS plc that, as
a result of any change in or amendment to the laws or regulations or rulings
promulgated thereunder of the United Kingdom ("U.K.") or of any political
subdivision or taxing authority thereof or therein or any change in the official
application or interpretation of such laws, regulations or rulings, or any
change in the official application or interpretation of, or any execution of or
amendment to, any treaty or treaties affecting taxation to which the U.K. or
such political subdivision or taxing authority is a party, which change or
amendment becomes effective on or after December 13, 1996, (i) in making
payments in respect of principal or interest on Debentures that are part of
Book-Entry Capital Units (as defined in the Capital Unit Agreement) it would
become obligated to pay Additional Amounts with respect thereto as a result of
any withholding taxes or similar charges imposed by or for the account of the
U.K. or any political subdivision or taxing authority thereof or therein or (ii)
the payment of interest on the Debentures would be treated as a "distribution"
within the meaning of section 209 of the Income and Corporation Taxes Act 1988
of the U.K. (or any statutory modification or re-enactment thereof for the time
being).

                  "Tax Event Prepayment Price" means an amount equal to (i) if a
Tax Redemption occurs before February 28, 2007, the greater of (a) 100% of the
principal amount of such Debentures and (b) as determined by the Quotation Agent
(as defined below), the sum of the present values of the principal amount and
premium payable with respect to an optional redemption of such Debentures on
February 28, 2007, together with the sum of the present values of the scheduled
payments of interest from the prepayment date to February 28, 2007 (the
"Remaining Life"), all discounted to the prepayment date on a semi-annual basis
(assuming a 360-day year consisting of 30-day months) at the Adjusted Treasury
Rate (as defined below), plus, in each case, accrued interest thereon to but
excluding the date of prepayment or (ii) if a Tax Redemption occurs on or after
February 28, 2007, the redemption prices (expressed as percentages of principal
amount) set forth under the fourth immediately preceding paragraph.

                  With respect to a Tax Redemption occurring prior to February
28, 2007, the Corporation shall cause the Quotation Agent to provide the Trustee
with written notice of the Tax Event Prepayment Price promptly after the
calculation thereof.

                  "Adjusted Treasury Rate" means, with respect to any prepayment
date, the Treasury Rate (as defined below) plus (i) 1.00% if such prepayment
date occurs on or before February 28, 1998 or (ii) 0.50% if such prepayment date
occurs after February 28, 1998.

                  "Treasury Rate" means (i) the yield, under the heading which
represents the average for the immediately prior week, appearing in the most
recently published statistical release designated "H.15(519)" or any successor
publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on

                                        7

actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities", for the maturity corresponding
to the Remaining Life (if no maturity is within three months before or after the
Remaining Life, yields for the two published maturities most closely
corresponding to the Remaining Life shall be determined and the Treasury Rate
shall be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (ii) if such release (or any successor
release) is not published during the week preceding the calculation date or does
not contain such yields, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue (as defined below),
calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price (as
defined below) for such prepayment date. The Treasury Rate shall be calculated
on the third Business Day preceding the prepayment date.

                  "Comparable Treasury Issue" means with respect to any
prepayment date the United States Treasury security selected by the Quotation
Agent as having a maturity comparable to the Remaining Life that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the Remaining Life. If no United States Treasury security has a
maturity which is within a period from three months before to three months after
February 28, 2007, the two most closely corresponding United States Treasury
securities shall be used as the Comparable Treasury Issue, and the Treasury Rate
shall be interpolated or extrapolated on a straight-line basis, rounding to the
nearest month using such securities.

                  "Quotation Agent" means Morgan Stanley & Co. Incorporated and
its successors; provided, however, that if the foregoing shall cease to be a
primary U.S. Government securities dealer in New York City (a "Primary Treasury
Dealer"), the Corporation shall substitute therefor another Primary Treasury
Dealer. "Reference Treasury Dealer" means (i) the Quotation Agent or (ii) any
other Primary Treasury Dealer selected by the Trustee after consultation with
the Corporation.

                  "Comparable Treasury Price" means (i) the average of five
Reference Treasury Dealer Quotations (as defined below) for such prepayment
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of such Quotations.

                  "Reference Treasury Dealer Quotations" means, with respect to
each Reference Treasury Dealer and any prepayment date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.
New York City time, on the third Business Day preceding such prepayment date.

                  Any notice of a Tax Redemption given pursuant to Section 12.2
of the Indenture occuring prior to February 28, 2007, need not set forth the Tax
Event Prepayment Price but only the manner of calculation thereof.

                  All Debentures surrendered for transfer or exchange shall be
duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to, MS plc and the Trustee and executed by the
Holder or by the Holder's attorney duly authorized in writing. The Issuer may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any such exchange or registration
of transfer.]1

                  In case an Event of Default with respect to the Debentures

upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

                  Pursuant to the terms of the Indenture, the Guarantor has
unconditionally guaranteed on a subordinated basis to the Holder of each
Debenture evidenced hereby the due and punctual payment of the principal of and
interest on [(together with any Additional Amounts)]2, this Debenture when and
as the same shall become due and payable, whether at maturity or by declaration
of acceleration or otherwise, according to the terms of each such Debenture and
of the Indenture.

                  The indebtedness evidenced by this Debenture is subordinate,
to the extent and in the manner set forth in the Indenture, to the prior payment

full of all Senior Indebtedness of the Guarantor. Each holder of this Debenture,
by accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee as attorney-in-fact for any and all such purposes.

principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any amount payable on redemption thereof, or change

the enforcement of any payment on any Security when due or (ii) reduce the
aforesaid percentage in principal amount of Securities of any series issued
under such Indenture, the consent of the Holders of which is required for any
such modification. It is also provided in the Indenture that, with respect to
certain defaults or Events of Default regarding the Securities of any series,
prior to any declaration accelerating the maturity of such Securities, the
Holders of a majority in aggregate principal amount Outstanding of the
Securities of such series (or, in the case of certain defaults or Events of
Default, all or certain series of the Securities) may on behalf of the Holders
of all the Securities of such series (or all or certain series of the
Securities, as the case may be) waive any such past default or Event of Default
and its consequences. The preceding sentence shall not, however, apply to a
default in the payment of the principal of or interest and any Additional
Amounts on any of the Securities. Any such consent or waiver by the Holder of
this Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such Holder and upon all future Holders and owners of this
Debenture and any Securities which may be issued in exchange or substitution
herefor [or on registration of transfer hereof]1, irrespective of whether or not
any notation thereof is made upon this Debenture or such other Securities.

                       as holder hereunder (the "Holder")

                  Subject to the conditions hereinafter set forth, the Holder
agrees to purchase and pay for, and Morgan Stanley Group Inc., a corporation
duly incorporated and existing under the laws of the State of Delaware (the
"Corporation"), agrees to sell, for value received, on August 30, 2016 (the
"Stated Purchase Date") or, at the election of the Corporation, subject to the
terms of the Capital Unit Agreement referred to below, on any earlier Interest
Payment Date on or after February 28, 1998 (together with the Stated Purchase
Date, a "Purchase Date"), that number of Depositary Shares (the "Depositary
Shares"), each Depositary Share representing five (5) shares of 8.03% Cumulative
Preferred Stock, without par value, stated value $200.00 per share, of the
Corporation, corresponding to the number of Purchase Contracts specified [on the
face hereof]1 [on Schedule I hereto]2, at a purchase price of $1,000.00 per
Depositary Share, unless a Termination Event or Cancellation Event shall have
occurred on or prior to the Purchase Date. The Purchase Contract(s) evidenced
hereby shall not entitle the Holder to purchase Depositary Shares prior to a
Purchase Date or from and after the date a Termination Event has occurred.

                  The Purchase Price for the Depositary Shares purchased
pursuant to the Purchase Contracts evidenced hereby shall be payable at the
Corporate Trust Office of the Agent (i) by application of payments received by
the Agent with respect to the principal of the Debentures constituting a part of
the Capital Units of which the Purchase Contracts evidenced hereby form a part
(a "Debenture Settlement") or (ii) at the option of the Holder, upon written
notice to the Agent not less than 10 days nor more than 20 days prior to the
applicable Purchase Date, in such coin or currency of the United States of
America as at the

time of payment is legal tender for payment of public and private debts, to the
Agent in immediately available funds payable to or upon the order of the
Corporation delivered to the Agent not later than 12:00 P.M. New York City time
on the Business Day immediately preceding the Purchase Date (a "Cash
Settlement"). A Holder who fails to provide notice to the Agent as provided
above that it will make a Cash Settlement with respect to the settlement of a
Purchase Contract, or a Holder who provides such notice but does not make
payment in the manner provided above, will be deemed to have elected to make a
Debenture Settlement. In the event of a Debenture Settlement, the principal of
the Debenture included in the Capital Unit of which such Purchase Contract
constitutes a part will be paid to the Agent upon surrender to the Agent of the
Capital Unit Certificate representing such Capital Unit.

                  The Holder, by his acceptance hereof, covenants and agrees
that, to the extent and in the manner provided in the Capital Unit Agreement,
but subject to the terms thereof, payments in respect of principal of the
Debentures constituting a part of the Capital Units of which the Purchase
Contracts evidenced hereby form a part, in the absence of a Cash Settlement by
the Holder, shall be applied by the Agent in satisfaction of the Holder's
obligations under such Purchase Contracts. [In the event that the Holder elects
to make a Cash Settlement with respect to his obligations under the Purchase
Contracts evidenced hereby with respect to which a Purchase Date is occurring,
the Holder must properly effect a Cash Settlement with respect to all (but not
less than all) of such Purchase Contracts.]1 [In the event that a beneficial
holder, as specified in the records of the direct and indirect participants of
the Depositary and as certified in writing by such beneficial holder, of
Purchase Contracts evidenced hereby elects to make a Cash Settlement with
respect to his obligations under Purchase Contracts evidenced hereby with
respect to which a Purchase Date is occurring, the beneficial holder must
properly effect a Cash Settlement with respect to all (but not less than all) of
the Purchase Contracts beneficially held.]2

                  The Purchase Contracts evidenced hereby and the obligations
and rights of the Corporation and the Holder hereunder shall terminate if a
Termination Event shall have occurred. "Termination Event" is defined in the
Capital Unit Agreement to mean any of the following events: (i) the occurrence
of a Bankruptcy Event at any time on or prior to the Stated Purchase Date; or
(ii) the existence of a Cancellation Condition at 5:00 P.M. New York City time
on the date that is five Business Days prior to the Stated Purchase Date.

                  Each Purchase Contract evidenced hereby is one of a duly
authorized issue of contracts of the Corporation relating to the purchase of an
aggregate of not more than 134,000 Depositary Shares at an aggregate purchase
price of $134,000,000, issued and to be

issued under a Capital Unit Agreement, dated as of December 18, 1996 (the
"Capital Unit Agreement"), among the Corporation, Morgan Stanley Finance plc
("MS plc"), The Chase Manhattan Bank, as Agent and Book-Entry Unit Depositary
(in its capacity as agent, herein called the "Agent" and, in its capacity as
Book-Entry Unit Depositary, the "Book-Entry Unit Depositary") and as Trustee
under the Indenture referred to therein and the holders from time to time of
Capital Units, to which Capital Unit Agreement and supplemental agreements
thereto reference is hereby made for a description of the respective rights,
limitations of rights, obligations, duties and immunities thereunder of the
Agent, the Book-Entry Unit Depositary, the Corporation, MS plc and the Holders
and of the terms upon which the Purchase Contracts are, and are to be, executed,
countersigned and delivered.

                  The Agent may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents in connection with any transfer
or exchange. No service charge shall be required for any such registration of
transfer or exchange, but MS plc, the Corporation, the Agent and the Book-Entry
Unit Depositary may require payment of a sum sufficient to cover any tax or
other governmental charge imposed in connection with any registration of
transfer or exchange of Capital Units. Except as provided in the Capital Unit
Agreement, the Purchase Contracts are not separable from the Debentures
constituting a part of the Capital Units of which the Purchase Contracts
evidenced hereby form a part, and may be transferred only together with a
corresponding number of Debentures.

                  Upon registration of transfer of a Capital Unit, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent), under the terms of
the Capital Unit Agreement and the Purchase Contracts evidenced thereby and the
transferor shall be released from the obligations under the Purchase Contracts
evidenced by the Capital Units so transferred. The Corporation covenants and
agrees, and the Holder, by his acceptance hereof, likewise covenants and agrees,
to be bound by the provisions of this paragraph.

                  The Corporation may, at its option, accelerate to any Interest
Payment Date that is on or after February 28, 1998 the closing of the purchase
of 50,000 or more Purchase Contracts upon not less than 30 and not more than 60
days' notice, subject to cancellation and termination in the circumstances set
forth in the next paragraph, provided that no partial acceleration may result in
fewer than 50,000 Purchase Contracts remaining Outstanding after such closing.

                  The Corporation will not be entitled to accelerate the
obligations of the Holder to any Accelerated Purchase Date, and notice of any
such acceleration will be automatically rescinded and annulled, if, at 5:00 P.M.
New York City time on the date that is five business days prior to such
Accelerated Purchase Date, a Cancellation Condition exists. The rescission of
any notice of acceleration as set forth above will not prevent the


<PAGE>

                                        4

Corporation from giving notice of an Accelerated Purchase Date with respect to
any Purchase Contracts at a later date.

                  Any or all of the Purchase Contracts may be redeemed at the
option of the Corporation, or from time to time in part, upon not less than 30
and not more than 60 days' notice, on any Interest Payment Date on or after
February 28, 2007, at a redemption price equal to $1.00 per Purchase Contract,
provided that no partial redemption shall result in fewer than 50,000 Unsettled
Purchase Contracts remaining Outstanding after such redemption, or in accordance
with the next two succeeding paragraphs, at any other time when the Debentures
are redeemed.

                  In the event that MS plc shall redeem a Debenture constituting
part of a Capital Unit pursuant to the provisions of the Indenture, the
Corporation shall redeem the Purchase Contract constituting part of the same
Capital Unit on the redemption date of such related Debenture.

                  In the event that MS plc shall redeem Debentures constituting
part of Capital Units pursuant to a Tax Redemption, the Corporation shall redeem
all Purchase Contracts then Outstanding on the redemption date of the
Debentures.

                  Subject to certain exceptions, the terms of the Purchase
Contracts and the provisions of the Capital Unit Agreement relating to or
affecting the Purchase Contracts may be amended with the consent of the affected
Holders of not less than a majority of the Outstanding Capital Units and certain
Purchase Contract Defaults may be waived with the consent of the Holders of a
majority of the Outstanding Capital Units. Without the consent of any Holder of
Capital Units, the terms of the Capital Unit Agreement relating to the Purchase
Contracts may be amended to cure any ambiguity, to correct or supplement any
provision in the Capital Unit Agreement with respect to and affecting the
Purchase Contracts, to evidence the assumption of the Corporation's covenants
with respect to or affecting the Purchase Contracts or to make any other
provisions with respect to matters or questions arising under the Capital Unit
Agreement with respect to or affecting the Purchase Contracts that do not
adversely affect the interests of the Holders in any material respect.

                  Holders of the Purchase Contracts may not enforce the Capital
Unit Agreement or such Purchase Contracts except as provided in the Capital Unit
Agreement.

                  An incorporator, or past, present or future stockholder,
officer, attorney-in-fact or director, as such, of the Corporation or MS plc
shall not have any liability for any obligations of the Corporation or MS plc
under the Purchase Contracts or the Capital Unit Agreement or for any claim
based on, with respect to or by reason of such obligations or their creation.
The Holder by his acceptance hereof waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the Purchase

                  The Purchase Contracts shall for all purposes be governed by,
and construed in accordance with, the laws of the State of New York.

Global Purchase Contract for registration of transfer, MS plc, the Corporation,
the Trustee, the Book-Entry Unit Depositary and the Agent, and any agent of MS
