         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by

substantially similar tenor signed by such Holders in person or by 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 and, where it is hereby expressly required, to the Company. 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 7.1) conclusive in favor of the Agent and the
Company, 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 which the Agent deems
sufficient.

         (d) Any request, demand, authorization, direction, notice, consent,

Holder of the same Certificate and the Holder of every Certificate issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Agent or the
Company in reliance thereon, whether or not notation of such action is made upon
such Certificate.

         (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Agreement to be given, made or taken by
Holders of Securities. If any record date is set pursuant to this paragraph, the
Holders of the Outstanding Normal Units and the Outstanding Stripped Units, as
the case may be, on such record date, and no other Holders, shall be entitled to
take the relevant action with respect to the Normal Units or the Stripped Units,
as the case may be, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite number of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Company from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be cancelled and of no effect), and nothing in this paragraph
shall be construed to render ineffective any action taken by Holders of the
requisite number of Outstanding Securities on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company,
at its own expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Agent in
writing and to each Holder of Securities in the manner set forth in Section 1.6.

Company may designate any date as the "Expiration Date" and from time to time

such change shall be effective unless notice of the proposed new Expiration Date
is given to the Agent in writing, and to each Holder of Securities in the manner
set forth in Section 1.6, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section, the Company shall be deemed to have initially designated the
180th day after such record date as the Expiration Date with respect thereto,
subject to its right to change the Expiration Date as provided in this
paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than
the 180th day after the applicable record date.

Section 1.5.      Notices.

notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the applicable Register, 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




                                       12
<PAGE>


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.

thereof.

Section 3.2.      Rights and Obligations Evidenced by the Certificates.

         Each Normal Unit Certificate shall evidence the number of Normal Units
specified therein, with each such Normal Unit representing the ownership by the
Holder thereof of a beneficial interest in a Debt Security or the Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, subject to the
Pledge of such Debt Security or the Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, by such Holder pursuant to the Pledge
Agreement, and the rights and obligations of the Holder thereof and the Company
under one Purchase Contract. The Agent as attorney-in-fact for, and on behalf
of, the Holder of each Normal Unit shall pledge, pursuant to the Pledge
Agreement, the Debt Security or the Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, forming a part of such Normal Unit, to
the Collateral Agent and grant to the Collateral Agent a security interest in
the right, title, and interest of such Holder in such Debt Security or the
Applicable Ownership Interest in the Treasury Portfolio, as the case may be, for
the benefit of the Company, to secure the obligation of the Holder under each
Purchase Contract to purchase the Common Stock of the Company. Prior to the
purchase of Common Stock under each Purchase Contract, the Purchase Contracts
shall not entitle the Holders of Normal Unit Certificates to any of the rights
of a holder





                                       15

of Common Stock, including, without limitation, the right to vote or receive any
dividends or other payments or to consent or to receive notice as stockholders
in respect of the meetings of stockholders or for the election of directors of
the Company or for any other matter, or any other rights whatsoever as
stockholders of the Company.

         Each Stripped Unit Certificate shall evidence the number of Stripped
Units specified therein, with each such Stripped Unit representing the ownership
by the Holder thereof of a ___th undivided beneficial interest in a Treasury
Security, subject to the Pledge of such interest in such Treasury Security by
such Holder pursuant to the Pledge Agreement, and the rights and obligations of
the Holder thereof and the Company under one Purchase Contract. Prior to the
purchase of Common Stock under each Purchase Contract, the Purchase Contracts
shall not entitle the Holders of Stripped Unit Certificates to any of the rights
of a holder of Common Stock, including, without limitation, the right to vote or
receive any dividends or other payments or to consent or to receive notice as
stockholders in respect of the meetings of stockholders or for the election of
directors of the Company or for any other matter, or any other rights whatsoever
as stockholders of the Company.

Section 3.3.      Execution, Authentication, Delivery and Dating.

         Subject to the provisions of Sections 3.13 and 3.14 hereof, upon the
execution and delivery of this Agreement, and at any time and from time to time
thereafter, the Company may deliver Certificates executed by the Company to the
Agent for authentication, execution on behalf of the Holders and delivery,
together with its Issuer Order for authentication of such Certificates, and the
Agent in accordance with such Issuer Order shall authenticate, execute on behalf
of the Holders and deliver such Certificates.

         The Certificates shall be executed on behalf of the Company by the
Chairman of the Board, the Vice Chairman, the President, the Chief Financial
Officer, the Chief Administrative Officer, General Counsel, Secretary or any
Vice President (or other officer performing similar functions) of the Company
and delivered to the Agent. The signature of any of these officers on the
Certificates may be manual or facsimile.

         Certificates bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Certificates or did not
hold such offices at the date of such Certificates.

         No Purchase Contract evidenced by a Certificate shall be valid until
such Certificate has been executed on behalf of the Holder by the manual
signature of an authorized signatory of the Agent, as such Holder's
attorney-in-fact. Such signature by an authorized signatory of the Agent shall
be conclusive evidence that the Holder of such Certificate has entered into the
Purchase Contracts evidenced by such Certificate.

         Each Certificate shall be dated the date of its authentication.

         No Certificate shall be entitled to any benefit under this Agreement or
be valid or obligatory for any purpose unless there appears on such Certificate
a certificate of authentication substantially in the form provided for herein
executed by an authorized signatory of the Agent by




                                       16
<PAGE>



manual signature, and such certificate upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

Section 3.4.      Temporary Certificates.

         Pending the preparation of definitive Certificates, the Company shall
execute and deliver to the Agent, and the Agent shall authenticate, execute on
behalf of the Holders, and deliver, in lieu of such definitive Certificates,
temporary Certificates which are in substantially the form set forth in Exhibit
A or Exhibit B hereto, as the case may be, 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 Normal Units or Stripped Units are listed, or
as may, consistently herewith, be determined by the officers of the Company
executing such Certificates, as evidenced by their execution of the
Certificates.

         If temporary Certificates are issued, the Company will cause definitive
Certificates to be prepared without unreasonable delay. After the preparation of
definitive Certificates, the temporary Certificates shall be exchangeable for
definitive Certificates upon surrender of the temporary Certificates at the
Corporate Trust Office, at the expense of the Company and without charge to the
Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Company shall execute and deliver to the Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver in exchange
therefor, one or more definitive Certificates of like tenor and denominations
and evidencing a like number of Normal Units or Stripped Units, as the case may
be, as the temporary Certificate or Certificates so surrendered. Until so
exchanged, the temporary Certificates shall in all respects evidence the same
benefits and the same obligations with respect to the Normal Units or Stripped
Units, as the case may be, evidenced thereby as definitive Certificates.

Section 3.5.      Registration; Registration of Transfer and Exchange.

         The Agent shall keep at the Corporate Trust Office a register (the
"Normal Unit Register") in which, subject to such reasonable regulations as it
may prescribe, the Agent shall provide for the registration of Normal Unit
Certificates and of transfers of Normal Unit Certificates (the Agent, in such
capacity, the "Normal Unit Registrar") and a register (the "Stripped Unit
Register") in which, subject to such reasonable regulations as it may prescribe,
the Agent shall provide for the registration of the Stripped Unit Certificates
and transfers of Stripped Unit Certificates (the Agent, in such capacity, the
"Stripped Unit Registrar").

         Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office, the Company shall execute and deliver to the Agent, and
the Agent shall authenticate, execute on behalf of the designated transferee or
transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of any authorized denominations, like
tenor, and evidencing a like number of Normal Units or Stripped Units, as the
case may be.

         At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Normal Units or Stripped Units, as




                                       17
<PAGE>


the case may be, upon surrender of the Certificates to be exchanged at the
Corporate Trust Office. Whenever any Certificates are so surrendered for
exchange, the Company shall execute and deliver to the Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver the
Certificates which the Holder making the exchange is entitled to receive.

         All Certificates issued upon any registration of transfer or exchange
of a Certificate shall evidence the ownership of the same number of Normal Units
or Stripped Units, as the case may be, and be entitled to the same benefits and
subject to the same obligations, under this Agreement as the Normal Units or
Stripped Units, as the case may be, evidenced by the Certificate surrendered
upon such registration of transfer or exchange.

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

         No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company 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 connection with any registration of transfer or
exchange of Certificates, other than any exchanges pursuant to Sections 3.6 and
8.5 not involving any transfer.

         Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate
presented or surrendered for registration of transfer or for exchange on or
after the Business Day immediately preceding the earlier of the Purchase
Contract Settlement Date or the Termination Date. In lieu of delivery of a new
Certificate, upon satisfaction of the applicable conditions specified above in
this Section and receipt of appropriate registration or transfer instructions
from such Holder, the Agent shall (i) if the Purchase Contract Settlement Date
has occurred, deliver the number of Common Stock issuable in respect of the
Purchase Contracts forming a part of the Securities evidenced by such
Certificate, (ii) in the case of Normal Units, if a Termination Event shall have
occurred prior to the Purchase Contract Settlement Date, transfer the aggregate
Stated Amount of the Debt Securities or the Treasury Portfolio, as applicable,
evidenced thereby, or (iii) in the case of Stripped Units, if a Termination
Event shall have occurred prior to the Purchase Contract Settlement Date,
transfer the Treasury Securities evidenced thereby, in each case subject to the
applicable conditions and in accordance with the applicable provisions of
Article Five hereof.

Section 3.6.      Book-Entry Interests.

         The Certificates, on original issuance, will be issued in the form of
one or more, fully registered Global Certificates, to be delivered to the
Depositary by, or on behalf of, the Company. Such Global Certificate shall
initially be registered on the books and records of the Company in the name of
Cede & Co., the nominee of the Depositary, and no Beneficial Owner will receive
a definitive Certificate representing such Beneficial Owner's interest in such
Global Certificate, except as provided in Section 3.9. The Agent shall enter
into an agreement with the



                                       18

Certificate(s) and shall have no obligation to the Beneficial Owners;

         (c) to the extent that the provisions of this Section 3.6 conflict with
any other provisions of this Agreement, the provisions of this Section 3.6 shall
control; and

         (d) the rights of the Beneficial Owners shall be exercised only through
the Clearing Agency and shall be limited to those established by law and
agreements between such Beneficial Owners and the Clearing Agency and/or the
Clearing Agency Participants. The Clearing Agency will make book-entry transfers
among Clearing Agency Participants and receive and transmit interest payments on
the Debt Securities to such Clearing Agency Participants.

Section 3.7.      Notices to Holders.

         Whenever a notice or other communication to the Holders is required to
be given under this Agreement, the Company or the Company's agent shall give

Securities registered in the name of a Clearing Agency or the nominee of a
Clearing Agency, the Company or the Company's agent shall, except as set forth
herein, have no obligations to the Beneficial Owners.

Section 3.8.      Appointment of Successor Clearing Agency.

         If any Clearing Agency elects to discontinue its services as securities
depositary with respect to the Securities, the Company may, in its sole
discretion, appoint a successor Clearing Agency with respect to the Securities.

Section 3.9.      Definitive Certificates.

         If (i) a Clearing Agency elects to discontinue its services as
securities depositary with respect to the Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 3.8, (ii) the Company elects to terminate the book-entry system through
the Clearing Agency with respect to the Securities, or (iii) there shall have
occurred and be continuing a default by the Company in respect of its
obligations under one or more Purchase Contracts, then upon surrender of the
Global Certificates representing the Book-Entry Interests with respect to the
Securities by the Clearing Agency, accompanied by registration instructions, the
Company shall cause definitive Certificates to be delivered to Beneficial Owners
in accordance with the instructions of the Clearing Agency. The Company shall
not be liable for any delay in delivery of such instructions and may
conclusively rely on and shall be protected in relying on, such instructions.

Section 3.10.     Mutilated, Destroyed, Lost and Stolen Certificates.

         If any mutilated Certificate is surrendered to the Agent, the Company
shall execute and deliver to the Agent, and the Agent shall authenticate,
execute on behalf of the Holder, and deliver in exchange therefor, a new
Certificate at the cost of the Holder, evidencing the same number of Normal
Units or Stripped Units, as the case may be, and bearing a Certificate number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Agent (i) evidence
to their satisfaction of the destruction, loss or theft of any Certificate, and
(ii) such security or indemnity at the cost of the Holder 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 the Company or the Agent that such Certificate has been
acquired by a bona fide purchaser, the Company shall execute and deliver to the
Agent, and the Agent shall authenticate, execute on behalf of the Holder, and
deliver to the Holder, in lieu of any such destroyed, lost or stolen
Certificate, a new Certificate, evidencing the same number of Normal Units or
Stripped Units, as the case may be, and bearing a Certificate number not

execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the Purchase Contract Settlement Date or the Termination Date. In lieu of
delivery of a new Certificate, upon satisfaction of the applicable conditions
specified above in this Section and receipt of appropriate registration or
transfer instructions from such Holder, the Agent shall (i) if the Purchase
Contract Settlement Date has occurred, deliver the number of Common Stock

Company and the Agent may require the payment by the Holder 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 Certificate issued pursuant to this Section in lieu of any
destroyed, lost or stolen Certificate shall constitute an original additional
contractual obligation of the Company and of the Holder in respect of the
Security evidenced thereby, whether or not the destroyed, lost or stolen
Certificate (and the Securities evidenced thereby) shall be at any time
enforceable by anyone, and shall be entitled to all the benefits and be subject
to all the obligations of this Agreement equally and proportionately with any
and all other Certificates delivered hereunder.

         The provisions of this Section are exclusive and shall preclude (to the

Section 3.11.     Persons Deemed Owners.

         Prior to due presentment of a Certificate for registration of transfer,
the Company and the Agent, and any agent of the Company or the Agent, may treat
the Person in whose name such Certificate is registered as the owner of the
Normal Units or Stripped Units evidenced thereby, for the purpose of receiving
interest on the Debt Securities, if declared, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any interest on
the Debt Securities shall be overdue and notwithstanding any notice to the
contrary, and neither the Company nor the Agent, nor any agent of the Company or
the Agent, shall be affected by notice to the contrary.

         Notwithstanding the foregoing, with respect to any Global Certificate,
nothing herein shall prevent the Company, the Agent or any agent of the Company
or the Agent, from giving effect to any written certification, proxy or other
authorization furnished by any Clearing Agency (or its nominee), as a Holder,
with respect to such Global Certificate or impair, as between such Clearing
Agency and owners of beneficial interests in such Global Certificate, the
operation of customary practices governing the exercise of rights of such
Clearing Agency (or its nominee) as Holder of such Global Certificate.

         All Certificates surrendered for delivery of Common Stock on or after
the Purchase Contract Settlement Date, upon the transfer of Debt Securities ,
the appropriate Applicable Ownership Interest in the Treasury Portfolio or

Event or pursuant to an Early Settlement, or upon the registration of a transfer
or exchange of a Security, or a Collateral Substitution or the re-establishment
of a Normal Unit shall, if surrendered to any Person other than the Agent, be
delivered to the Agent and, if not already cancelled, shall be promptly
cancelled by it. The Company may at any time deliver to the Agent for
cancellation any Certificates previously authenticated, executed and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the
Agent. No Certificates shall be authenticated, executed on behalf of the Holder

cancelled Certificates held by the Agent shall be disposed of by the Agent in
accordance with its customary practices.

         If the Company or any Affiliate of the Company shall acquire any
Certificate, such acquisition shall not operate as a cancellation of such
Certificate unless and until such Certificate is delivered to the Agent
cancelled or for cancellation.

Section 3.13.     Establishment or Reestablishment of Stripped Units.

         A Holder may separate the Debt Securities or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as applicable, from the related
Purchase Contracts in respect of a Normal Unit by substituting for such Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, Treasury Securities in an aggregate principal
amount [at maturity] equal to the aggregate Stated Amount of such Debt
Securities or



                                       21
<PAGE>


for the aggregate Stated Amount of the appropriate Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as applicable (a "Collateral Substitution"), at any time from and
after the date of this Agreement and on or prior to the fifth Business Day
immediately preceding the Purchase Contract Settlement Date and on or prior to
the second Business Day immediately preceding the Purchase Contract Settlement
Date in the case of the appropriate Applicable Ownership Interest in the
Treasury Portfolio, in each case by (a) depositing with the Collateral Agent
Treasury Securities having an aggregate principal amount [at maturity] equal to
the aggregate Stated Amount of the Debt Securities comprising part of such
Normal Unit or for the aggregate Stated Amount of the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio comprising part of such Normal Unit, as the case may
be, and (b) (i) by delivering cash in an amount equal to the excess of the
Contract Adjustment Payments that would have accrued since the last Payment Date
through the date of substitution on the Stripped Units being created by the
holder, over the Contract Adjustment Payments that have accrued over the same
time period on the related Normal Units, which amount the Agent shall promptly
remit to the Company, and (ii) transferring the related Normal Unit to the Agent
accompanied by a notice to the Agent, substantially in the form of Exhibit D
hereto, stating that the Holder has transferred the relevant amount of Treasury
Securities to the Collateral Agent and requesting that the Agent instruct the
Collateral Agent to release the Debt Securities or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, underlying
such Normal Unit, whereupon the Agent shall promptly give such instruction to
the Collateral Agent, substantially in the form of Exhibit C hereto. Upon
receipt of the Treasury Securities described in clause (a) above and the
instruction described in clause (b) above, in accordance with the terms of the
Pledge Agreement, the Collateral Agent will release to the Agent, on behalf of
the Holder, Debt Securities or the appropriate Applicable Ownership Interest in
the Treasury Portfolio, as the case may be, having a corresponding aggregate
Stated Amount of such Debt Securities or aggregate Stated Amount of the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, from the
Pledge, free and clear of the Company's security interest therein, and upon
receipt thereof the Agent shall promptly:

                  (i) cancel the related Normal Unit;

                  (ii) transfer the related Debt Securities or the appropriate
         Applicable Ownership Interest in the Treasury Portfolio, as the case
         may be, to the Holder; and

                  (iii) authenticate, execute on behalf of such Holder and
         deliver a Stripped Unit Certificate executed by the Company in
         accordance with Section 3.3 evidencing the same number of Purchase
         Contracts as were evidenced by the cancelled Normal Unit.

         Holders who elect to separate the Debt Securities or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
from the related Purchase Contract and to substitute Treasury Securities for
such Debt Securities or the appropriate Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, shall be responsible for any fees or
expenses payable to the Collateral Agent for its services as Collateral Agent in
respect of the substitution, and the Company shall not be responsible for any
such fees or expenses.




                                       22
<PAGE>


         Holders may make Collateral Substitutions (i) only in integral
multiples of Normal Units if Debt Securities are being substituted by Treasury
Securities, or (ii) only in integral multiples of Normal Units if the
appropriate Applicable Ownership Interests of the Treasury Portfolio are being
substituted by Treasury Securities.

         In the event a Holder making a Collateral Substitution pursuant to this
Section 3.13 fails to effect a book-entry transfer of the Normal Units or fails
to deliver a Normal Unit Certificate to the Agent after depositing Treasury
Securities with the Collateral Agent, the Debt Securities or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
constituting a part of such Normal Unit, and any interest on such Debt Security
or distributions with respect to the Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, shall be held in the name of the Agent
or its nominee in trust for the benefit of such Holder, until such Normal Units
are so transferred or the Normal Unit Certificate is so delivered, as the case
may be, or, with respect to a Normal Unit Certificate, such Holder provides
evidence satisfactory to the Company and the Agent that such Normal Unit
Certificate has been destroyed, lost or stolen, together with any indemnity that
may be required by the Agent and the Company.

         Except as described in this Section 3.13, for so long as the Purchase
Contract underlying a Normal Unit remains in effect, such Normal Unit shall not
be separable into its constituent parts, and the rights and obligations of the
Holder in respect of the Debt Securities or the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, and Purchase Contract
comprising such Normal Unit may be acquired, and may be transferred and
exchanged, only as a Normal Unit.

Section 3.14.     Establishment or Reestablishment of Normal Units.

         A Holder of a Stripped Unit may create or recreate Normal Units at any
time on or prior to the fifth Business Day immediately preceding the Purchase
Contract Settlement Date on or prior to the second Business Day immediately
preceding the Purchase Contract Settlement Date, if a Tax Event Redemption has
occurred, in each case by (a) depositing with the Collateral Agent Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, having an aggregate principal amount in the case
of Debt Securities, or an aggregate Stated Amount of the appropriate Applicable
Ownership Interest (as defined in clause (A) of the definition of such term) of
the Treasury Portfolio, as the case may be, equal to the aggregate principal
amount at maturity of the Pledged Treasury Securities comprising part of the
Stripped Unit and (b) transferring the related Stripped Unit to the Agent
accompanied by a notice to the Agent, substantially in the form of Exhibit D
hereto, stating that the Holder has transferred the relevant amount of Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, to the Collateral Agent and requesting that the
Agent instruct the Collateral Agent to release the Treasury Securities
underlying such Stripped Unit, whereupon the Agent shall promptly give such
instruction to the Collateral Agent, substantially in the form of Exhibit C
hereto. Upon receipt of the Debt Securities or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, described in
clause (a) above and the instruction described in clause (b) above, in
accordance with the terms of the Pledge Agreement, the Collateral Agent will
effect the release of the Treasury Securities having a corresponding aggregate
principal amount at maturity from the Pledge to the Agent free and





                                       23
<PAGE>



clear of the Company's security interest therein, and upon receipt thereof the
Agent shall promptly:

                  (i) cancel the related Stripped Unit;

                  (ii) transfer the Treasury Securities to the Holder; and

                  (iii) authenticate, execute on behalf of such Holder and
         deliver a Normal Unit Certificate executed by the Company in accordance
         with Section 3.3 evidencing the same number of Purchase Contracts as
         were evidenced by the cancelled Stripped Unit.

         Holders of Stripped Units may establish or reestablish Normal Units in
integral multiples of ___ Stripped Units for ___ Debt Securities only.

         Except as provided in this Section 3.14, for so long as the Purchase
Contract underlying a Stripped Unit remains in effect, such Stripped Unit shall
not be separable into its constituent parts and the rights and obligations of
the Holder of such Stripped Unit in respect of the Treasury Security and
Purchase Contract comprising such Stripped Unit may be acquired, and may be
transferred and exchanged only as a Stripped Unit.

Section 3.15.     Transfer of Collateral upon Occurrence of Termination Event.

         Upon the occurrence of a Termination Event and the transfer to the
Agent of the Debt Securities , the appropriate Applicable Ownership Interest in
the Treasury Portfolio or the Treasury Securities, as the case may be,
underlying the Normal Units and the Stripped Units pursuant to the terms of the
Pledge Agreement, the Agent shall request transfer instructions with respect to
such Debt Securities or the appropriate Applicable Ownership Interest in the
Treasury Portfolio or Treasury Securities, as the case may be, from each Holder
by written request mailed to such Holder at its address as it appears in the
Normal Unit Register or the Stripped Unit Register, as the case may be. Upon
book-entry transfer of the Normal Units or Stripped Units or delivery of a
Normal Unit Certificate or Stripped Unit Certificate to the Agent with such
transfer instructions, the Agent shall transfer the Debt Securities, the
Treasury Portfolio or Treasury Securities, as the case may be, underlying such
Normal Units or Stripped Units, as the case may be, to such Holder by book-entry
transfer, or other appropriate procedures, in accordance with such instructions.
In the event a Holder of Normal Units or Stripped Units fails to effect such
transfer or delivery, the Debt Securities, the appropriate Applicable Ownership
Interest in the Treasury Portfolio or Treasury Securities, as the case may be,
underlying such Normal Units or Stripped Units, as the case may be, and any
distributions thereon, shall be held in the name of the Agent or its nominee in
trust for the benefit of such Holder, until such Normal Units or Stripped Units
are transferred or the Normal Unit Certificate or Stripped Unit Certificate is
surrendered or such Holder provides satisfactory evidence that such Normal Unit
Certificate or Stripped Unit Certificate has been destroyed, lost or stolen,
together with any indemnity that may be required by the Agent and the Company.
In the case of the Treasury Portfolio or any Treasury Securities, the Agent may
dispose of the subject securities for cash and pay the applicable portion of
such cash to the Holders in lieu of such Holders' Applicable Ownership Interest
in such Treasury Portfolio, or any Treasury Securities, where such Holder would
otherwise have been entitled to receive less than $1,000 of any such security.

Section 3.16.     No Consent To Assumption.

         Each Holder of a Security, by acceptance thereof, shall be deemed
expressly to have withheld any consent to the assumption under Section 365 of
the Bankruptcy Code or otherwise, of the Purchase Contract by the Company, its
trustee in bankruptcy, receiver, liquidator or a person or entity performing
similar functions, its trustee in the event that the Company becomes a debtor
under the Bankruptcy Code or subject to other similar state or federal law
providing for reorganization or liquidation.

Section 3.17.     CUSIP Numbers.

         The Company in issuing the Securities may use CUSIP numbers (if then
generally in use), and, if so, the Agent shall use CUSIP numbers in notices as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Agent of any
change in the CUSIP numbers.

                               THE DEBT SECURITIES

Section 4.1.      Payment of Interest; Rights to Interest Preserved; Interest
                  Rate Reset; Notice.

         Interest on any Debt Security or distribution with respect to the
appropriate Applicable Ownership Interest in the Treasury Portfolio, as the case
may be, which is paid on any Payment Date shall, subject to receipt thereof by
the Agent from the Collateral Agent as provided by the terms of the Pledge
Agreement, be paid to the Person in whose name the Normal Unit Certificate (or
one or more Predecessor Normal Unit Certificates) of which such Debt Security or
the appropriate Applicable Ownership Interest in the Treasury Portfolio, as the
case may be, is a part is registered at the close of business on the Record Date
for such Payment Date.

         Each Normal Unit Certificate evidencing Debt Securities delivered under
this Agreement upon registration of transfer of or in exchange for or in lieu of
any other Normal Unit Certificate shall carry the rights to accrued and unpaid
interest, and to accrue interest, which were carried by the Debt Securities
underlying such other Normal Unit Certificate.

         In the case of any Normal Units with respect to which Cash Settlement
of the underlying Purchase Contract is effected on the Business Day immediately
preceding the Purchase Contract Settlement Date pursuant to prior notice, or
with respect to which Early Settlement of the underlying Purchase Contract is
effected on an Early Settlement Date, or with respect to which a Collateral
Substitution is effected, in each case on a date that is after any Record Date
and on or prior to the next succeeding Payment Date, interest on the Debt
Securities or distribution with respect to the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, underlying such Normal
Units otherwise payable on such Payment Date shall be payable on such Payment
Date notwithstanding such Cash Settlement or Early Settlement or Collateral
Substitution, and such interest or distribution shall, subject to receipt
thereof by the Agent, be payable to the Person in whose name the Normal Unit
Certificate (or one or more Predecessor




                                       25
<PAGE>


Normal Unit Certificates) was registered at the close of business on the Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Normal Units with respect to which Cash Settlement
or Early Settlement of the underlying Purchase Contract is effected on the
Business Day immediately preceding the Purchase Contract Settlement Date or an
Early Settlement Date, as the case may be, or with respect to which a Collateral
Substitution has been effected, interest on the related Debt Securities or
distributions with respect to the appropriate Applicable Ownership Interest in
the Treasury Portfolio, as the case may be, that would otherwise be payable
after the Purchase Contract Settlement Date or Early Settlement Date shall not
be payable hereunder to the Holder of such Normal Units; provided, however, that
to the extent that such Holder continues to hold the separated Debt Securities
that formerly comprised a part of such Holder's Normal Units, such Holder shall
be entitled to receive the interest on such separated Debt Securities.

         The applicable Coupon Rate on the Debt Securities on and after the
Purchase Contract Settlement Date will be reset on the third Business Day
immediately preceding the Purchase Contract Settlement Date to the Reset Rate
(such Reset Rate to be in effect on and after the Purchase Contract Settlement
Date). On the Reset Announcement Date, the Reset Spread and [the One-Month
Treasury Bill] to be used to determine the Reset Rate will be announced by the
Company. On the Business Day immediately following the Reset Announcement Date,
the Debt Securities Holders will be notified of such Reset Spread [and the
One-Month Treasury Bill] by the Company. Such notice shall be sufficiently given
to Holders of Debt Securities if published in an Authorized Newspaper in The
City of New York.

         Not less than 7 calendar days nor more than 15 calendar days prior to
the Reset Announcement Date, the Company will notify DTC or its nominee (or any
successor Clearing Agency or its nominee) by first-class mail, postage prepaid,
to notify the Beneficial Owners or Clearing Agency Participants holding Normal
Units or Stripped Units, of such Reset Announcement Date and the procedures to
be followed by such Holders of Normal Units who intend to settle their
obligation under the Purchase Contract with separate cash on the Purchase
Contract Settlement Date.

Section 4.2.      Notice and Voting.

         Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Debt
Securities pledged with the Collateral Agent but only to the extent instructed
by the Holders as described below. Upon receipt of notice of any meeting at
which holders of Debt Securities are entitled to vote or upon any solicitation
of consents, waivers or proxies of holders of Debt Securities, the Agent shall,
as soon as practicable thereafter, mail to the Holders of Normal Units a notice
(a) containing such information as is contained in the notice or solicitation,
(b) stating that each Holder on the record date set by the Agent therefor
(which, to the extent possible, shall be the same date as the record date for
determining the holders of Debt Securities entitled to vote) shall be entitled
to instruct the Agent as to the exercise of the voting rights pertaining to the
Debt Securities underlying their Normal Units and (c) stating the manner in
which such instructions may be given. Upon the written request of the Holders of
Normal Units on such record date, the Agent shall endeavor insofar as
practicable to vote or cause to be voted, in accordance with the instructions
set forth in such requests, the maximum number of Debt Securities as to which
any particular voting





                                       26
<PAGE>


instructions are received. In the absence of specific instructions from the
Holder of a Normal Unit, the Agent shall abstain from voting the Debt Security
underlying such Normal Unit. The Company hereby agrees, if applicable, to
solicit Holders of Normal Units to timely instruct the Agent in order to enable
the Agent to vote such Debt Securities.

Section 4.3.      Tax Event Redemption.

         Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, the Redemption Price payable on the Tax Event
Redemption Date with respect to the Applicable Principal Amount of Debt
Securities shall be delivered to the Collateral Agent in exchange for the
Pledged Debt Securities. Pursuant to the terms of the Pledge Agreement, the
Collateral Agent will apply an amount equal to the Redemption Amount of such
Redemption Price to purchase on behalf of the Holders of Normal Units the
Treasury Portfolio and promptly remit the remaining portion of such Redemption
Price to the Agent for payment to the Holders of such Normal Units. The Treasury
Portfolio will be substituted for the Pledged Debt Securities, and will be held
by the Collateral Agent in accordance with the terms of the Pledge Agreement to
secure the obligation of each Holder of a Normal Unit to purchase the Common
Stock of the Company under the Purchase Contract constituting a part of such
Normal Unit. Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Normal Units and the
Collateral Agent shall have such security interests, rights and obligations with
respect to the Treasury Portfolio as the Holder of Normal Units and the
Collateral Agent had in respect of the Debt Security subject to the Pledge
thereof as provided in Articles II, III, IV, V, and VI of the Pledge Agreement,
and any reference herein to the Debt Securities shall be deemed to be reference
to such Treasury Portfolio. The Company may cause to be made in any Normal Units
thereafter to be issued such change in phraseology and form (but not in
substance) as may be appropriate to reflect the liquidation of the Trust and the
substitution of the Treasury Portfolio for Debt Securities as collateral.

[Section 4.4.     Consent To Treatment For Tax Purposes.

         Each Holder of Normal Units or Stripped Units, by its acceptance
thereof, covenants and agrees to treat itself as the owner, for United States
federal, state and local income and franchise tax purposes, of (i) the related
Debt Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, in the case of the Normal Units, or (ii) the Treasury Securities, in
the case of the Stripped Units. Each Holder of Normal Units, by its acceptance
thereof, further covenants and agrees to treat the Debt Securities as
indebtedness of the Company for United States federal, state and local income
and franchise tax purposes.]

                             THE PURCHASE CONTRACTS

Section 5.1.      Purchase of Common Stock.

         Each Purchase Contract shall, unless an Early Settlement has occurred
in accordance with Section 5.7 hereof, obligate the Holder of the related
Security to purchase, and the Company to sell, on the Purchase Contract
Settlement Date at a price equal to the Stated Amount (the





                                       27
<PAGE>

"Purchase Price"), a number of newly issued shares of Common Stock equal to the
Settlement Rate unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if
the Applicable Market Value (as defined below) is equal to or greater than $-
(the "Threshold Appreciation Price"), - Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price,
but is greater than $- (the "Threshold Depreciation Price"), the number of
Common Stock equal to the Stated Amount divided by the Applicable Market Value
and (c) if the Applicable Market Value is less than or equal to Threshold
Depreciation Price, - Common Stock per Purchase Contract, in each case subject
to adjustment as provided in Section 5.4 (and in each case rounded upward or
downward to the nearest 1/10,000th of a share). As provided in Section 5.8, no
fractional shares of Common Stock will be issued upon settlement of Purchase
Contracts.

         The "Applicable Market Value" means the average of the Closing Prices
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Purchase Contract Settlement
Date.

         The "Closing Price" of the shares of Common Stock on any date of
determination means the closing sale price (or, if no closing price is reported,
the last reported sale price) of the Common Stock on the New York Stock Exchange
(the "NYSE") on such date or, if the shares of Common Stock are not listed for
trading on the NYSE on any such date, as reported in the composite transactions
for the principal United States securities exchange on which the shares of
Common Stock are so listed, or if the shares of Common Stock are not so listed
on a United States national or regional securities exchange, as reported by The
Nasdaq Stock Market, or, if the shares of Common Stock are not so reported, the
last quoted bid price for the Common Stock in the over-the-counter market as
reported by the National Quotation Bureau or similar organization, or, if such
bid price is not available, the market value of the Common Stock on such date as
of 4:00 p.m., New York City time, as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company.

         A "Trading Day" means a day on which the shares of Common Stock (A) are
not suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) have
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

         Each Holder of a Normal Unit or a Stripped Unit, by its acceptance
thereof, irrevocably authorizes the Agent to enter into and perform the related
Purchase Contract on its behalf as its attorney-in-fact (including the execution
of Certificates on behalf of such Holder), agrees to be bound by the terms and
provisions thereof, covenants and agrees to perform its obligations under such
Purchase Contracts, and consents to the provisions hereof, irrevocably
authorizes the Agent as its attorney-in-fact to enter into and perform the
Pledge Agreement on its behalf as its attorney-in-fact, and consents to and
agrees to be bound by the Pledge of the Debt Securities, the Treasury Portfolio
or the Treasury Securities pursuant to the Pledge Agreement; provided that upon
a Termination Event, the rights of the Holder of such Security under the
Purchase Contract may be enforced without regard to any other rights or
obligations. Each Holder of a Normal Unit or a Stripped Unit, by its acceptance
thereof, further covenants and agrees, that, to the extent and




                                       28
<PAGE>


in the manner provided in Section 5.2 and the Pledge Agreement, but subject to
the terms thereof, payments in respect of the Stated Amount of the Debt
Securities or the Proceeds of the Treasury Securities or the Treasury Portfolio
on the Purchase Contract Settlement Date shall be paid by the Collateral Agent
to the Company in satisfaction of such Holder's obligations under such Purchase
Contract and such Holder shall acquire no right, title or interest in such
payments.

         Upon registration of transfer of a Certificate, the transferee shall be
bound (without the necessity of any other action on the part of such
transferee), under the terms of this Agreement, the Purchase Contracts
underlying such Certificate and the Pledge Agreement and the transferor shall be
released from the obligations under this Agreement, the Purchase Contracts
underlying the Certificates so transferred and the Pledge Agreement. The Company
covenants and agrees, and each Holder of a Certificate, by its acceptance
thereof, likewise covenants and agrees, to be bound by the provisions of this
paragraph.

Section 5.2.      Payment of Purchase Price.

         (a) (i) Unless a Holder settles the underlying Purchase Contract
through the early delivery of cash to the Agent in the manner described in
Section 5.7, each Holder of a Normal Unit must notify the Agent by use of a
notice in substantially the form of Exhibit E hereto of its intention to pay in
cash ("Cash Settlement") the Purchase Price for the Common Stock to be purchased
pursuant to a Purchase Contract. Such notice shall be made on or prior to 5:00
p.m., New York City time, on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date. The Agent shall promptly notify the
Collateral Agent of the receipt of such a notice from a Holder intending to make
a Cash Settlement.

             (ii) A Holder of a Normal Unit who has so notified the Agent of its
intention to make a Cash Settlement is required to pay the Purchase Price to the
Collateral Agent prior to 11:00 a.m., New York City time, on the Business Day
immediately preceding the Purchase Contract Settlement Date in lawful money of
the United States by certified or cashiers' check or wire transfer, in each case
in immediately available funds payable to or upon the order of the Company. Any
cash received by the Collateral Agent will be invested promptly by the
Collateral Agent in Permitted Investments and paid to the Company on the
Purchase Contract Settlement Date in settlement of the Purchase Contract in
accordance with the terms of this Agreement and the Pledge Agreement. Any funds
received by the Collateral Agent in respect of the investment earnings from the
investment in such Permitted Investments will be distributed to the Agent when
received for payment to the Holder.

             (iii) If a Holder of a Normal Unit fails to notify the Agent of its
intention to make a Cash Settlement in accordance with paragraph (a)(i) above,
such failure shall constitute an event of default and the Holder shall be deemed
to have consented to the disposition of the pledged Debt Securities pursuant to
the remarketing as described in paragraph (b) below. If a Holder of a Normal
Unit does notify the Agent as provided in paragraph (a)(i) above of its
intention to pay the Purchase Price in cash, but fails to make such payment as
required by paragraph (a)(ii) above, such failure shall also constitute a
default; however, the Debt Securities of such a Holder will not be remarketed
but instead the Collateral Agent, for the benefit of the Company, will exercise
its rights as a secured party with respect to such Debt Securities, including
those rights specified in paragraph (c) below.




                                       29
<PAGE>


         (b) In order to dispose of the Debt Securities of Normal Units Holders
who have not notified the Agent of their intention to effect a Cash Settlement
as provided in paragraph (a)(i) above, the Company shall engage a nationally
recognized investment bank (the "Remarketing Agent") pursuant to the Remarketing
Agreement to sell such Debt Securities. In order to facilitate the remarketing,
the Agent shall notify, by 10:00 a.m., New York City time, on the fourth
Business Day immediately preceding the Purchase Contract Settlement Date, the
Remarketing Agent of the aggregate number of Debt Securities to be remarketed.
Concurrently, the Collateral Agent, pursuant to the terms of the Pledge
Agreement, will present for remarketing such Debt Securities to the Remarketing
Agent. Upon receipt of such notice from the Agent and such Debt Securities from
the Collateral Agent, the Remarketing Agent will, on the third Business Day
immediately preceding the Purchase Contract Settlement Date, use its reasonable
efforts to remarket such Debt Securities on such date at a price of
approximately -% (but not less than -%) of the aggregate principal amount of
such Debt Securities, plus accrued and unpaid interest, if any, thereon. After
deducting as the remarketing fee ("Remarketing Fee") an amount not exceeding -
basis points (-%) of the aggregate stated liquidation amount of the remarketed
Debt Securities from any amount of such proceeds in excess of the aggregate
principal amount of the remarketed Debt Securities plus accrued and unpaid
interest, if any, then the Remarketing Agent will remit the entire amount of the
proceeds from such remarketing to the Collateral Agent. Such portion of the
proceeds, equal to the aggregate principal amount of such Debt Securities, will
automatically be applied by the Collateral Agent, in accordance with the Pledge
Agreement to satisfy in full such Normal Units holders' obligations to pay the
Purchase Price for the Common Stock under the related Purchase Contracts on the
Purchase Contract Settlement Date. Any proceeds in excess of those required to
pay the Purchase Price and the Remarketing Fee will be remitted to the Agent for
payment to the Holders of the related Normal Units. Normal Units Holders whose
Debt Securities are so remarketed will not otherwise be responsible for the
payment of any Remarketing Fee in connection therewith. If, in spite of using
its reasonable efforts, the Remarketing Agent cannot remarket the related Debt
Securities of such Holders of Normal Units at a price not less then -% of the
aggregate principal amount of such Debt Securities plus accrued and unpaid
interest, if any, the remarketing will be deemed to have failed (a "Failed
Remarketing") and in accordance with the terms of the Pledge Agreement, the
Collateral Agent for the benefit of the Company will exercise its rights as a
secured party with respect to such Debt Securities, including those actions
specified in paragraph (c) below; provided, that if upon a Failed Remarketing
the Collateral Agent exercises such rights for the benefit of the Company with
respect to such Debt Securities, any accrued and unpaid interest on such Debt
Securities will become payable by the Company to the Agent for payment to the
Beneficial Owner of the Normal Units to which such Debt Securities relates. Such
payment will be made by the Company on or prior to 11 a.m., New York City time,
on the Purchase Contract Settlement Date in lawful money of the United States by
certified or cashiers' check or wire transfer in immediately available funds
payable to or upon the order of the Agent. The Company will cause a notice of
such Failed Remarketing to be published on the second Business Day immediately
preceding the Purchase Contract Settlement Date in an Authorized Newspaper in
The City of New York.

         (c) With respect to any Debt Securities beneficially owned by Holders
who have elected Cash Settlement but failed to deliver cash as required in
(a)(ii) above, or with respect to Debt Securities which are subject to a Failed
Remarketing, the Collateral Agent for the benefit of the






                                       30
<PAGE>

Company reserves all of its rights as a secured party with respect thereto and,
subject to applicable law and paragraph (g) below, may, among other things, (i)
retain the Debt Securities in full satisfaction of the Holders obligations under
the Purchase Contracts or (ii) sell the Debt Securities in one or more public or
private sales.

         (d) (i) Unless a Holder of Stripped Units settles the underlying
Purchase Contract through the early delivery of cash to the Agent in the manner
described in Section 5.7, each Holder of a Stripped Unit must notify the Agent
by use of a notice in substantially the form of Exhibit E hereto of its
intention to pay in cash the Purchase Price for the Common Stock to be purchased
pursuant to a Purchase Contract on or prior to 5:00 p.m., New York City time, on
the second Business Day immediately preceding the Purchase Contract Settlement
Date.

             (ii) A Holder of a Stripped Unit who has so notified the Agent of
its intention to make a Cash Settlement in accordance with paragraph (d)(i)
above is required to pay the Purchase Price to the Collateral Agent prior to
11:00 a.m., New York City time, on the Business Day immediately preceding the
Purchase Contract Settlement Date in lawful money of the United States by
certified or cashiers' check or wire transfer, in each case in immediately
available funds payable to or upon the order of the Company. Any cash received
by the Collateral Agent will be invested promptly by the Collateral Agent in
specific Permitted Investments as directed in writing by the Company and paid to
the Company on the Purchase Contract Settlement Date in settlement of the
Purchase Contract in accordance with the terms of this Agreement and the Pledge
Agreement. Any funds received by the Collateral Agent in respect of the
investment earnings from the investment in such Permitted Investments will be
distributed to the Agent when received for payment to the Holder.

             (iii) If a Holder of a Stripped Unit notifies the Agent of its
intention to make a Cash Settlement in accordance with paragraph (d)(i) above,
but fails to make such payment as required by paragraph (d)(ii) above, then upon
the maturity of the Pledged Treasury Securities or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, held by the
Collateral Agent on the Business Day immediately prior to the Purchase Contract
Settlement Date, the principal amount at maturity of the Treasury Securities or
the appropriate Applicable Ownership Interest in the Treasury Portfolio, as the
case may be, received by the Collateral Agent will be invested promptly in
specific overnight Permitted Investments as directed in writing by the Company.
On the Purchase Contract Settlement Date, an amount equal to the Purchase Price
will be remitted to the Company as payment thereof without receiving any
instructions from the Holder. In the event the sum of the proceeds from the
related Pledged Treasury Securities or the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, and the investment
earnings earned from such investments is in excess of the aggregate Purchase
Price of the Purchase Contracts being settled thereby, the Collateral Agent will
distribute such excess to the Agent for the benefit of the Holder of the related
Stripped Unit when received.

         (e) Any distribution to Holders of excess funds and interest described
above shall be payable at the office of the Agent in The City of New York
maintained for that purpose or, at the option of the Holder, by check mailed to
the address of the Person entitled thereto at such address as it appears on the
Register.




                                       31
<PAGE>


         (f) Unless a Holder settles the underlying Purchase Contract through
the early delivery of cash to the Collateral Agent in the manner described
herein, the Company shall not be obligated to issue any Common Stock in respect
of a Purchase Contract or deliver any certificate therefor to the Holder unless
it shall have received payment in full of the Purchase Price for the Common
Stock to be purchased thereunder in the manner herein set forth.

         Upon Cash Settlement of any Purchase Contract, (i) the Collateral Agent
will in accordance with the terms of the Pledge Agreement cause the Pledged Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, or the Pledged Treasury Securities underlying the
relevant Security to be released from the Pledge by the Collateral Agent free
and clear of any security interest of the Company and transferred to the Agent
for delivery to the Holder thereof or its designee as soon as practicable and
(ii) subject to the receipt thereof from the Collateral Agent, the Agent shall,
by book-entry transfer, or other appropriate procedures, in accordance with
instructions provided by the Holder thereof, transfer such Debt Securities or
the appropriate Applicable Ownership Interest in the Treasury Portfolio, as the
case may be, or such Treasury Securities (or, if no such instructions are given
to the Agent by the Holder, the Agent shall hold such Debt Securities or the
appropriate Applicable Ownership Interest in the Treasury Portfolio, as the case
may be, or such Treasury Securities, and any interest payable thereon, in the
name of the Agent or its nominee in trust for the benefit of such Holder).

         (g) The obligations of the Holders to pay the Purchase Price are
non-recourse obligations and are payable solely out of any Cash Settlement or
the proceeds of any Collateral Pledged to secure the obligations of the Holders
and in no event will Holders be liable for any deficiency between the proceeds
of Collateral disposition and the Purchase Price.

Section 5.3.      Issuance of Common Stock.

         Unless a Termination Event shall have occurred on or prior to the
Purchase Contract Settlement Date or an Early Settlement shall have occurred, on
the Purchase Contract Settlement Date, upon its receipt of payment in full of
the Purchase Price for the Common Stock purchased by the Holders pursuant to the
foregoing provisions of this Article and subject to Section 5.4(b), the Company
shall issue and deposit with the Agent, for the benefit of the Holders of the
Outstanding Securities, one or more certificates representing the newly issued
Common Stock registered in the name of the Agent (or its nominee) as custodian
for the Holders (such certificates for Common Stock, together with any dividends
or distributions for which a record date and payment date for such dividend or
distribution has occurred after the Purchase Contract Settlement Date, being
hereinafter referred to as the "Purchase Contract Settlement Fund") to which the
Holders are entitled hereunder. Subject to the foregoing, upon surrender of a
Certificate to the Agent on or after the Purchase Contract Settlement Date,
together with settlement instructions thereon duly completed and executed, the
Holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of Common Stock which such
Holder is entitled to receive pursuant to the provisions of this Article Five
(after taking into account all Securities then held by such Holder) together
with cash in lieu of fractional shares as provided in Section 5.8 and any
dividends or distributions with respect to such shares constituting part of the
Purchase Contract Settlement Fund, but without any interest thereon, and the
Certificate so surrendered shall forthwith be cancelled. Such shares




                                       32
<PAGE>

shall be registered in the name of the Holder or the Holder's designee as
specified in the settlement instructions provided by the Holder to the Agent. If
any shares of Common Stock issued in respect of a Purchase Contract are to be
registered to a Person other than the Person in whose name the Certificate
evidencing such Purchase Contract is registered, no such registration shall be
made unless the Person requesting such registration has paid any transfer and
other taxes required by reason of such registration in a name other than that of
the registered Holder of the Certificate evidencing such Purchase Contract or
has established to the satisfaction of the Company that such tax either has been
paid or is not payable.

Section 5.4.      Adjustment of Settlement Rate.

        (a)       Adjustments for Dividends, Distributions, Stock Splits, Etc.

                  (1) In case the Company shall pay or make a dividend or other
distribution on the Common Stock in Common Stock, the Settlement Rate, as in
effect at the opening of business on the day following the date fixed for the
determination of shareholders entitled to receive such dividend or other
distribution shall be increased by dividing such Settlement Rate by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination. For the purposes of this paragraph (1), the
number of shares of Common Stock at the time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of Common
Stock. The Company will not pay any dividend or make any distribution on Common
Stock held in the treasury of the Company.

                  (2) In case the Company shall issue rights, options or
warrants to all holders of its Common Stock (not being available on an
equivalent basis to Holders of the Securities upon settlement of the Purchase
Contracts underlying such Securities) entitling them, for a period expiring
within 45 days after the record date for the determination of shareholders
entitled to receive such rights, options or warrants, to subscribe for or
purchase Common Stock at a price per share less than the Current Market Price
per share of Common Stock on the date fixed for the determination of
shareholders entitled to receive such rights, options or warrants (other than
pursuant to a dividend reinvestment plan), the Settlement Rate in effect at the
opening of business on the day following the date fixed for such determination
shall be increased by dividing such Settlement Rate by a fraction, the numerator
of which shall be the number of shares of Common Stock outstanding at the close
of business on the date fixed for such determination plus the number of shares
of Common Stock which the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription or purchase would purchase at
such Current Market Price and the denominator of which shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination. For the purposes of this paragraph (2), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include any shares issuable in respect of any
scrip certificates




                                       33
<PAGE>

issued in lieu of fractions of Common Stock. The Company shall not issue any
such rights, options or warrants in respect of Common Stock held in the treasury
of the Company.

                  (3) In case outstanding Common Stock shall be subdivided or
split into a greater number of shares of Common Stock, the Settlement Rate in
effect at the opening of business on the day following the day upon which such
subdivision or split becomes effective shall be proportionately increased, and,
conversely, in case outstanding Common Stock shall each be combined into a
smaller number of shares of Common Stock, the Settlement Rate in effect at the
opening of business on the day following the day upon which such combination
becomes effective shall be proportionately reduced, such increase or reduction,
as the case may be, to become effective immediately after the opening of
business on the day following the day upon which such subdivision, split or
combination becomes effective.

                  (4) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock evidences of its indebtedness or
assets (including securities, but excluding any rights or warrants referred to
in paragraph (2) of this Section, any dividend or distribution paid exclusively
in cash and any dividend or distribution referred to in paragraph (1) of this
Section), the Settlement Rate shall be adjusted so that the same shall equal the
rate determined by dividing the Settlement Rate in effect immediately prior to
the close of business on the date fixed for the determination of shareholders
entitled to receive such distribution by a fraction, the numerator of which
shall be the Current Market Price per share of Common Stock on the date fixed
for such determination less the then fair market value (as determined by the
Board of Directors, whose determination shall be conclusive and described in a
Board Resolution filed with the Agent) of the portion of the assets or evidences
of indebtedness so distributed applicable to one share of Common Stock and the
denominator of which shall be such Current Market Price per share of Common
Stock, such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
shareholders entitled to receive such distribution. In any case in which this
paragraph (4) is applicable, paragraph (2) of this Section shall not be
applicable.

                  (5) In case the Company shall, (I) by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding any cash that is
distributed in a Reorganization Event to which Section 5.4(b) applies or as part
of a distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with (II) the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this
Section has been made and (III) the aggregate of any cash plus the fair market
value (as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) of consideration payable in
respect of any tender or exchange offer by the Company or any of its
subsidiaries for all or any portion of the Common Stock concluded within the 12
months preceding the date of payment of the distribution described in clause (I)
above and in respect of which no adjustment pursuant to this paragraph (5) or
paragraph (6) of this Section has been made, exceeds 5% of the product of the
Current Market Price per share of Common Stock on the date for the determination
of holders of Common Stock entitled to receive such distribution times the
number of shares of Common Stock outstanding on such date, then, and in each
such case, immediately after the close of business on such date for
determination, the Settlement Rate shall be increased






                                       34
<PAGE>

so that the same shall equal the rate determined by dividing the Settlement Rate
in effect immediately prior to the close of business on the date fixed for
determination of the stockholders entitled to receive such distribution by a
fraction (i) the numerator of which shall be equal to the Current Market Price
per share of Common Stock on the date fixed for such determination less an
amount equal to the quotient of (x) the combined amount distributed or payable
in the transactions described in clauses (I), (II) and (III) above and (y) the
number of shares of Common Stock outstanding on such date for determination and
(ii) the denominator of which shall be equal to the Current Market Price per
share of Common Stock on such date for determination.

(6) In case (I) a tender or exchange offer made by the Company or any subsidiary
of the Company for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to shareholders (based on the acceptance (up to any maximum
specified in the terms of the tender or exchange offer) of Purchased Shares) of
an aggregate consideration having a fair market value (as determined by the
Board of Directors, whose determination shall be conclusive and described in a
Board Resolution) that combined together with (II) the aggregate of the cash
plus the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution), as of
the expiration of such tender or exchange offer, of consideration payable in
respect of any other tender or exchange offer, by the Company or any subsidiary
of the Company for all or any portion of the Common Stock expiring within the 12
months preceding the expiration of such tender or exchange offer and in respect
of which no adjustment pursuant to paragraph (5) of this Section or this
paragraph (6) has been made and (III) the aggregate amount of any distributions
to all holders of the Company's Common Stock made exclusively in cash within the
12 months preceding the expiration of such tender or exchange offer and in
respect of which no adjustment pursuant to paragraph (5) of this Section or this
paragraph (6) has been made, exceeds 5% of the product of the Current Market
Price per share of Common Stock as of the last time (the "Expiration Time")
tenders could have been made pursuant to such tender or exchange offer (as it
may be amended) times the number of shares of Common Stock outstanding
(including any tendered shares) on the Expiration Time, then, and in each such
case, immediately prior to the opening of business on the day after the date of
the Expiration Time, the Settlement Rate shall be adjusted so that the same
shall equal the rate determined by dividing the Settlement Rate immediately
prior to the close of business on the date of the Expiration Time by a fraction
(i) the numerator of which shall be equal to (A) the product of (I) the Current
Market Price per share of Common Stock on the date of the Expiration Time and
(II) the number of shares of Common Stock outstanding (including any tendered
shares) on the Expiration Time less (B) the amount of cash plus the fair market
value (determined as aforesaid) of the aggregate consideration payable to
shareholders based on the transactions described in clauses (I), (II) and (III)
above (assuming in the case of clause (I) the acceptance, up to any maximum
specified in the terms of the tender or exchange offer, of Purchased Shares),
and (ii) the denominator of which shall be equal to the product of (A) the
Current Market Price per share of Common Stock as of the Expiration Time and (B)
the number of shares of Common Stock outstanding (including any tendered shares)
as of the Expiration Time less the number of all shares validly tendered and not
withdrawn as of the Expiration Time (the shares deemed so accepted, up to any
such maximum, being referred to as the "Purchased Shares").

                  (7) The reclassification of Common Stock into securities
including securities other than Common Stock (other than any reclassification
upon a Reorganization Event to which Section 5.4(b) applies) shall be deemed to
involve (a) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall
be deemed to be "the date fixed for the determination of stockholders entitled
to receive such distribution" and the "date fixed for such determination" within
the meaning of paragraph (4) of this Section), and (b) a subdivision, split or
combination, as the case may be, of the number of shares of Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Common Stock outstanding immediately thereafter (and the effective date of
such reclassification shall be deemed to be "the day upon which such subdivision
or split becomes effective" or "the day upon which such combination becomes
effective", as the case may be, and "the day upon which such subdivision, split
or combination becomes effective" within the meaning of paragraph (3) of this
Section).

                  (8) The "Current Market Price" per share of Common Stock on
any day means the average of the daily Closing Prices for the 5 consecutive
Trading Days selected by the Company commencing not more than 30 Trading Days
before, and ending not later than, the earlier of the day in question and the
day before the "ex date" with respect to the issuance or distribution requiring
such computation. For purposes of this paragraph, the term "ex date", when used
with respect to any issuance or distribution, shall mean the first date on which
the Common Stock trades regular way on such exchange or in such market without
the right to receive such issuance or distribution.

                  (9) All adjustments to the Settlement Rate, shall be
calculated to the nearest 1/10,000th of a share of Common Stock (or if there is
not a nearest 1/10,000th of a share to the next lower 1/10,000th of a share). No
adjustment in the Settlement Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent therein; provided,
however, that any adjustments which by reason of this subparagraph are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. If an adjustment is made to the Settlement Rate pursuant
to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.4(a),
an adjustment shall also be made to the Applicable Market Value solely to
determine which of clauses (a), (b) or (c) of the definition of Settlement Rate
in Section 5.1 will apply on the Purchase Contract Settlement Date. Such
adjustment shall be made by multiplying the Applicable Market Value by a
fraction, the numerator of which shall be the Settlement Rate immediately after
such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10)
of this Section 5.4(a) and the denominator of which shall be the Settlement Rate
immediately before such adjustment; provided, however, that if such adjustment
to the Settlement Rate is required to be made pursuant to the occurrence of any
of the events contemplated by paragraph (1) (2) (3) (4) (5) (7) or (10) of this
Section 5.4(a) during the period taken into consideration for determining the
Applicable Market Value, appropriate and customary adjustments shall be made to
the Settlement Rate.

                  (10) The Company may make such increases in the Settlement
Rate, in addition to those required by this Section, as it considers to be
advisable in order to avoid or diminish any income tax to any holders of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons.




                                       36

         (b) Adjustment for Consolidation, Merger or Other Reorganization Event.
In the event of (i) any consolidation or merger of the Company with or into
another Person (other than a merger or consolidation in which the Company is the
continuing corporation and in which the Common Stock outstanding immediately
prior to the merger or consolidation is not exchanged for cash, securities or
other property of the Company or another corporation), (ii) any sale, transfer,
lease or conveyance to another Person of the property of the Company as an
entirety or substantially as an entirety, (iii) any statutory exchange of
securities of the Company with another Person (other than in connection with a
merger or acquisition) or (iv) any liquidation, dissolution or winding up of the
Company other than as a result of or after the occurrence of a Termination Event
(any such event, a "Reorganization Event"), the Settlement Rate will be adjusted
to provide that each Holder of Securities will receive on the Purchase Contract
Settlement Date with respect to each Purchase Contract forming a part thereof,
the kind and amount of securities, cash and other property receivable upon such
Reorganization Event (without any interest thereon, and without any right to
dividends or distribution thereon which have a record date that is prior to the
Purchase Contract Settlement Date) by a Holder of the number of Common Stock
issuable on account of each Purchase Contract if the Purchase Contract
Settlement Date had occurred immediately prior to such Reorganization Event
assuming such Holder of Common Stock is not a Person with which the Company
consolidated or into which the Company merged or which merged into the Company
or to which such sale or transfer was made, as the case may be (any such Person,
a "Constituent Person"), or an Affiliate of a Constituent Person to the extent
such Reorganization Event provides for different treatment of Common Stock held
by Affiliates of the Company and non-affiliates and such Holder failed to
exercise his rights of election, if any, as to the kind or amount of securities,
cash and other property receivable upon such Reorganization Event (provided that
if the kind or amount of securities, cash and other property receivable upon
such Reorganization Event is not the same for each share of Common Stock held
immediately prior to such Reorganization Event by other than a Constituent
Person or an Affiliate thereof and in respect of which such rights of election
shall not have been exercised ("non-electing share"), then for the purpose of
this Section the kind and amount of securities, cash and other property
receivable upon such Reorganization Event by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares). In the event of such a Reorganization Event, the Person
formed by such consolidation, merger or exchange or the Person which acquires
the assets of the Company or, in the event of a liquidation or dissolution of
the Company, the Company or a liquidating trust created in connection therewith,
shall execute and deliver to the Agent an agreement supplemental hereto
providing that the Holders of each Outstanding Security shall have the rights
provided by this Section 5.6. Such supplemental agreement shall provide for
adjustments which, for events subsequent to the effective date of such
supplemental agreement, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Section. The above provisions of this
Section shall similarly apply to successive Reorganization Events.

Section 5.5.      Notice of Adjustments and Certain Other Events.

        (a) Whenever the Settlement Rate is adjusted as herein provided, the
Company shall:

                  (i) forthwith compute the Settlement Rate in accordance with
         Section 5.4 and prepare and transmit to the Agent an Officer's
         Certificate setting forth the Settlement




                                       37
<PAGE>

         Rate, the method of calculation thereof in reasonable detail, and the
         facts requiring such adjustment and upon which such adjustment is
         based; and

                  (ii) within 10 Business Days following the occurrence of an
         event that requires an adjustment to the Settlement Rate pursuant to
         Section 5.4 (or if the Company is not aware of such occurrence, as soon
         as practicable after becoming so aware), provide a written notice to
         the Holders of the Securities of the occurrence of such event and a
         statement in reasonable detail setting forth the method by which the
         adjustment to the Settlement Rate was determined and setting forth the
         adjusted Settlement Rate.

         (b) The Agent shall not at any time be under any duty or responsibility
to any Holder of Securities to determine whether any facts exist which may
require any adjustment of the Settlement Rate, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the
method employed in making the same. The Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any share of Common
Stock, or of any securities or property, which may at the time be issued or
delivered with respect to any Purchase Contract; and the Agent makes no
representation with respect thereto. The Agent shall not be responsible for any
failure of the Company to issue, transfer or deliver any Common Stock pursuant
to a Purchase Contract or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article.

Section 5.6.      Termination Event; Notice.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights and
obligations of Holders to purchase Common Stock, shall immediately and
automatically terminate, without the necessity of any notice or action by any
Holder, the Agent or the Company, if, on or prior to the Purchase Contract
Settlement Date, a Termination Event shall have occurred. Upon and after the
occurrence of a Termination Event, the Securities shall thereafter represent the
right to receive the Debt Securities or the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, forming a part of such
Securities in the case of Normal Units, or Treasury Securities in the case of
Stripped Units, in accordance with the provisions of Section 4.3 of the Pledge
Agreement. Upon the occurrence of a Termination Event, the Company shall
promptly but in no event later than two Business Days thereafter give written
notice to the Agent, the Collateral Agent and to the Holders, at their addresses
as they appear in the Register.

Section 5.7.      Early Settlement.

         (a) Subject to and upon compliance with the provisions of this Section
5.7, at the option of the Holder thereof, Purchase Contracts underlying
Securities, having an aggregate Stated Amount equal to $1,000 or an integral
multiple thereof, may be settled early ("Early Settlement") in the case of
Normal Units (unless a Tax Event Redemption has occurred) on or prior to the
fifth Business Day immediately preceding the Purchase Contract Settlement Date
and in the case of Stripped Units on or prior to the second Business Day
immediately preceding the Purchase Contract Settlement Date, in each case, as
provided herein; provided however, that if a Tax Event Redemption has occurred
and the Treasury Portfolio has become a component of the Normal Units, Purchase
Contracts underlying Normal Units may be settled early, on or prior to







                                       38
<PAGE>


the second Business Day immediately preceding the Purchase Contract Settlement
Date, but only in an aggregate amount of $__________ or in an integral multiple
thereof. . In order to exercise the right to effect Early Settlement with
respect to any Purchase Contracts, the Holder of the Certificate evidencing
Securities shall deliver such Certificate to the Agent at the Corporate Trust
Office duly endorsed for transfer to the Company or in blank with the form of
Election to Settle Early on the reverse thereof duly completed and accompanied
by payment (payable to the Company in immediately available funds in an amount
(the "Early Settlement Amount") equal to (i) the product of (A) the Stated
Amount times (B) the number of Purchase Contracts with respect to which the
Holder has elected to effect Early Settlement plus (ii) in the case of Normal
Unit Certificates, if such delivery is made with respect to any Purchase
Contracts during the period from the close of business on any Record Date next
preceding any Payment Date to the opening of business on such Payment Date, an
amount equal to the sum of the dividends on the related Debt Securities payable
on such Payment Date. Except as provided in the immediately preceding sentence,
no payment or adjustment shall be made upon Early Settlement of any Purchase
Contract on account of any dividends on the Common Stock issued upon such Early
Settlement. If the foregoing requirements are first satisfied with respect to
Purchase Contracts underlying any Securities at or prior to 5:00 p.m., New York
City time, on a Business Day, such day shall be the "Early Settlement Date" with
respect to such Securities and if such requirements are first satisfied after
5:00 p.m., New York City time, on a Business Day or on a day that is not a
Business Day, the "Early Settlement Date" with respect to such Securities shall
be the next succeeding Business Day.

         (b) Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, the Company shall issue, and the Holder shall be entitled to
receive, _______ shares of Common Stock on account of each Purchase Contract as
to which Early Settlement is effected (the "Early Settlement Rate"). The Early
Settlement Rate shall be adjusted in the same manner and at the same time as the
Settlement Rate is adjusted. As promptly as practicable after Early Settlement
of Purchase Contracts in accordance with the provisions of this Section 5.7, the
Company shall issue and shall deliver to the Agent at the Corporate Trust Office
a certificate or certificates for the full number of shares of Common Stock
issuable upon such Early Settlement together with payment in lieu of any
fraction of a share, as provided in Section 5.8.

         (c) No later than the third Business Day after the applicable Early
Settlement Date the Company shall cause (i) the Common Stock issuable upon Early
Settlement of Purchase Contracts to be issued and delivered, and (ii) the
related Debt Securities or the appropriate Applicable Ownership Interest in the
Treasury Portfolio, in the case of Normal Units, or the related Treasury
Securities, in the case of Stripped Units, to be released from the Pledge by the
Collateral Agent and transferred, in each case to the Agent for delivery to the
Holder thereof or its designee.

         (d) Upon Early Settlement of any Purchase Contracts, and subject to
receipt of Common Stock from the Company and the Debt Securities, the
Appropriate Applicable Ownership Interest in The Treasury Portfolio or Treasury
Securities, as the case may be, from the Collateral Agent, as applicable, the
Agent shall, in accordance with the instructions provided by the Holder thereof
on the applicable form of Election to Settle Early on the reverse of the
Certificate evidencing the related Securities, (i) transfer to the Holder the
Debt Securities Treasury Portfolio or Treasury Securities, as the case may be,
forming a part of such Securities, and (ii) deliver to the Holder a





                                       39
<PAGE>

certificate or certificates for the full number of shares of Common Stock
issuable upon such Early Settlement together with payment in lieu of any
fraction of a share, as provided in Section 5.8.

         (e) In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Securities evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the Agent
shall authenticate, countersign and deliver to the Holder thereof, at the
expense of the Company, a Certificate evidencing the Securities as to which
Early Settlement was not effected.

Section 5.8.      No Fractional Shares.

         No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Purchase Contract
Settlement Date or upon Early Settlement of any Purchase Contracts. If
Certificates evidencing more than one Purchase Contract shall be surrendered for
settlement at one time by the same Holder, the number of full shares of Common
Stock which shall be delivered upon settlement shall be computed on the basis of
the aggregate number of Purchase Contracts evidenced by the Certificates so
surrendered. Instead of any fractional shares of Common Stock which would
otherwise be deliverable upon settlement of any Purchase Contracts on the
Purchase Contract Settlement Date or upon Early Settlement, the Company, through
the Agent, shall make a cash payment in respect of such fractional interest in
an amount equal to the value of such fractional shares times the Applicable
Market Value. The Company shall provide the Agent from time to time with
sufficient funds to permit the Agent to make all cash payments required by this
Section 5.8 in a timely manner.

Section 5.9.      Charges and Taxes.

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the Common Stock pursuant to the
Purchase Contracts; provided, however, that the Company shall not be required to
pay any such tax or taxes which may be payable in respect of any exchange of or
substitution for a Certificate evidencing a Security or any issuance of a share
of Common Stock in a name other than that of the registered Holder of a
Certificate surrendered in respect of the Securities evidenced thereby, other
than in the name of the Agent, as custodian for such Holder, and the Company
shall not be required to issue or deliver such share certificates or
Certificates unless or until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

                                   ARTICLE VI
                                    REMEDIES

Section 6.1.      Unconditional Right of Holders to Purchase Common Stock.

         The Holder of any Normal Units or Stripped Units shall have the right,
which is absolute and unconditional, to purchase Common Stock pursuant to the
Purchase Contract constituting a part of such Security and to institute suit for
the enforcement of any such right to purchase




                                       40
<PAGE>

Common Stock and payment and such rights shall not be impaired without the
consent of such Holder.

Section 6.2.      Restoration of Rights and Remedies.

         If any Holder 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, the
Company and such Holder shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of such Holder
shall continue as though no such proceeding had been instituted.

Section 6.3.      Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Certificates in the last paragraph of
Section 3.10, no right or remedy herein conferred upon or reserved to the
Holders 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 6.4.      Delay or Omission Not Waiver.

         No delay or omission of any Holder to exercise any right or remedy upon
a default shall impair any such right or remedy or constitute a waiver of any
such right. 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.

Section 6.5.      Undertaking for Costs.

         All parties to this Agreement agree, and each Holder of Normal Units or
Stripped Units, by its acceptance of such Normal Units or Stripped Units 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 the Agent for any action taken, suffered or omitted by it as Agent,
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 and expenses, 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 Company, to any suit
instituted by the Agent, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of interest payments
on any Debt Securities, if declared, on or after the respective Payment Date
therefor in respect of any Security held by such Holder, or for enforcement of
the right to purchase Common Stock under the Purchase Contracts constituting
part of any Security held by such Holder.

Section 6.6.      Waiver of Stay or Extension Laws.

         The Company 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 enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Agreement; and the Company (to the extent that it may
lawfully do so) 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 or the Holders, but will suffer and permit the
execution of every such power as though no such law had been enacted.

                                  ARTICLE VII
                                    THE AGENT

Section 7.1.      Certain Duties and Responsibilities.

         (a) (1) The Agent undertakes to perform, with respect to the
Securities, such duties and only such duties as are specifically set forth in
this Agreement and the Pledge Agreement, and no implied covenants or obligations
shall be read into this Agreement against the Agent; and

         (2) in the absence of bad faith, willful misconduct or negligence on
its part, the Agent may, with respect to the Securities, conclusively rely, as
to the truth of the statements and the correctness of the opinions expressed
therein, upon certificates or opinions furnished to the Agent and conforming to
the requirements of this Agreement, but in the case of any certificates or
opinions which 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, but need not
confirm or investigate the accuracy of mathematical calculations stated therein.

         (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, its own bad faith, or its own willful misconduct, except that

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) 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 adequate indemnity is not provided
         to it.

         (c) Whether or not therein expressly so provided, every provision of
this Agreement relating to the conduct or affecting the liability of or

to the Company 60 days prior to the effective date of such resignation. If the
instrument of acceptance by a successor Agent required by Section 7.10 shall not

<PAGE>


                  (1) the Agent fails to comply with Section 310(b) of the TIA,
         as if the Agent were an indenture trustee under an indenture qualified
         under the TIA, after written request therefor by the Company or by any
         Holder who has been a bona fide Holder of a Security for at least six
         months; or

                  (2) the Agent shall cease to be eligible under Section 7.8 and

         adjudged a bankrupt or insolvent or a receiver 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) the Company by a Board Resolution may remove the
Agent, or (ii) any Holder who has been a bona fide Holder of a Security 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.

         (e) 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, the
Company, by a Board Resolution, shall promptly appoint a successor Agent and
shall comply with the applicable requirements of Section 7.10. If no successor
Agent shall have been so appointed by the Company and accepted appointment in
the manner required by Section 7.10, any Holder who has been a bona fide Holder
of a Security 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.

         (f) The Company 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 by mailing written notice of such event by

appear in the applicable Register. Each notice shall include the name of the
successor Agent and the address of its Corporate Trust Office.

Section 7.10.     Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Agent, every
such successor Agent so appointed shall execute, acknowledge and deliver to the
Company 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; but, on the request of the Company or the successor Agent, such
retiring Agent shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Agent all the rights, powers and
trusts 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.

         (b) Upon request of any such successor Agent, the Company 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.

of the Agent, shall be the successor of the Agent hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been
authenticated and executed on behalf of the Holders, but not delivered, by the
Agent then in office, any successor by merger, conversion or consolidation to
such Agent may adopt such authentication and execution and deliver the
Certificates so authenticated and executed with the same effect as if such
successor Agent had itself authenticated and executed such Securities.

Section 7.12.     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 received by the Agent in its

in writing to the Agent, and furnish to the Agent reasonable proof that each
such applicant has owned a Security 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 Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Agent shall, mail to all the Holders copies of the form of proxy or
other communication which is specified in such request, with reasonable
promptness after a tender to the Agent of the materials to be mailed and of
payment, or provision for the payment, of the reasonable expenses of such
mailing.

Section 7.13.     No Obligations of Agent.

         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, the Pledge Agreement or any Purchase Contract in respect of the

Agent shall have no obligation to perform such Purchase Contracts on behalf of
the Holders, except to the extent expressly provided in Article Five hereof.

Section 7.14.     Tax Compliance.

         (a) The Agent, on its own behalf and on behalf of the Company, will
comply with all applicable certification, information reporting and withholding
(including "backup" withholding) requirements imposed by applicable tax laws,
regulations or administrative practice with respect

required to be withheld to the appropriate taxing authority or its designated
agent.

         (b) The Agent shall comply with any written direction received from the
Company with respect to the reasonable 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 7.1(a)(2) hereof.

         (c) The Agent shall maintain all appropriate records documenting
compliance with such requirements, and shall make such records available, on
written request, to the Company or its authorized representative within a
reasonable period of time after receipt of such request.

entitled to vote on such amendment or proposal, and such amendment or proposal
shall not be effective except with the consent of Holders of not less than a
majority of such class.

         It shall not be necessary for any Act of Holders under this Section to

Section 9.1.      Covenant Not to Merge, Consolidate, Sell or Convey Property
                  Except Under Certain Conditions.

         The Company covenants that it will not merge or consolidate with any
other Person or sell, assign, transfer, lease or convey all or substantially all

transaction or a series of related transactions, unless (i) either the Company
shall be the continuing corporation, or the successor (if other than the
Company) shall expressly assume all the obligations of the Company under the
Purchase Contracts, the Debt Securities, this Agreement and the Pledge Agreement
by one or more supplemental agreements in form reasonably satisfactory to the
Agent and the Collateral Agent, executed and delivered to the Agent and the
Collateral Agent by such corporation, and (ii) the Company or such successor
corporation, as the case may be, shall not, immediately after such merger or

default in the performance of any covenant or condition hereunder, under any of
the Securities or under the Pledge Agreement.

Section 9.2.      Rights and Duties of Successor Corporation.

         In case of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance and upon any such assumption by a successor corporation in
accordance with Section 9.1, such successor corporation shall succeed to and be
substituted for the Company with the same effect as if it had been named herein
as the Company. Such successor corporation thereupon may cause to be signed, and
may issue either in its own name or in the name of DTE Energy Company any or all
of the Certificates evidencing Securities issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Agent; and, upon
the order of such successor corporation, instead of the Company, and subject to
all the terms, conditions and limitations in this Agreement prescribed, the
Agent shall authenticate and execute on behalf of the Holders and deliver any
Certificates which previously shall have been signed and delivered by the
officers of the Company to the Agent for authentication and execution, and any
Certificate evidencing Securities which such successor corporation thereafter
shall cause to be signed and delivered to the Agent for that purpose. All the
Certificates so issued shall in all respects have the






                                       50
<PAGE>


same legal rank and benefit under this Agreement as the Certificates theretofore
or thereafter issued in accordance with the terms of this Agreement as though
all of such Certificates had been issued at the date of the execution hereof.

         In case of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance such change in phraseology and form (but not in substance)
may be made in the Certificates evidencing Securities thereafter to be issued as
may be appropriate.

Section 9.3.      Opinion of Counsel Given to Agent.

         The Agent, subject to Sections 7.1 and 7.3, shall receive an Opinion of
Counsel as conclusive evidence that any such consolidation, merger, sale,
assignment, transfer, lease or conveyance, and any such assumption, complies
with the provisions of this Article and that all conditions precedent to the
consummation of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance have been met.

such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where 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 the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York for such purposes. The Company 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. The

                  (Form of Reverse of Normal Unit Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of (as may be supplemented from time to time, the
"Purchase Contract Agreement"), between the Company and [The Bank of New York, a
New York] banking corporation, as Purchase Contract Agent (including its
successors thereunder, herein called the "Agent"), to which Purchase Contract
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 Company, and the Holders and of the
terms upon which the Normal Unit Certificates are, and are to be, executed and
delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Normal Unit Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event or an Early Settlement with
respect to the Security of which such Purchase Contract is a part. The
"Settlement Rate" is equal to (a) if the Applicable Market Value (as defined
below) is equal to or greater than $- (the "Threshold Appreciation Price"), -
shares of Common Stock per Purchase Contract, (b) if the Applicable Market Value
is less than the Threshold Appreciation Price but is greater than $- (the
"Threshold Depreciation Price"), the number of shares of Common Stock per
Purchase Contract equal to the Stated Amount divided by the Applicable Market
Value and (c) if the Applicable Market Value is less than or equal to the
Threshold Depreciation Price, - shares of Common Stock per Purchase Contract, in
each case subject to adjustment as provided in the Purchase Contract Agreement.
No fractional shares of Common Stock will be issued upon settlement of Purchase
Contracts, as provided in the Purchase Contract Agreement.

         Each Purchase Contract evidenced hereby, which is settled either
through Early Settlement or Cash Settlement, shall obligate the Holder of the
related Normal Units to purchase at the Purchase Price, and the Company to sell,
a number of newly issued shares of Common Stock equal to the Early Settlement
Rate or the Settlement Rate, as applicable.

         The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Purchase Contract Settlement
Date.

         The "Closing Price" of the Common Stock on any date of determination
means the closing sale price (or, if no closing price is reported, the last
reported sale price) of the Common Stock on the New York Stock Exchange (the
"NYSE") on such date or, if the Common Stock is not listed for trading on the
NYSE on any such date, as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, or if the Common Stock is not so listed on a United States national or
regional securities exchange, as reported by The Nasdaq Stock Market, or, if the
Common Stock is not so reported, the last quoted bid price for the Common Stock
in the over-the-counter market as reported by the National Quotation Bureau or
similar organization, or, if such bid price is not available, the market value
of the Common Stock on such date as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company.




                                       A-6
<PAGE>


         A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of shares of the Common Stock.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Normal Unit Certificate shall pay the Purchase Price for the
Common Stock purchased pursuant to each Purchase Contract evidenced hereby by
effecting a Cash Settlement, or an Early Settlement or from the proceeds of a
remarketing of the related Pledged Debt Securities of such holders. A Holder of
Normal Units who does not elect, on or prior to 5:00 p.m., New York City time,
on the fifth Business Day immediately preceding the Purchase Contract Settlement
Date, to make an effective Cash Settlement or an Early Settlement, shall pay the
Purchase Price for the Common Stock to be issued under the related Purchase
Contract from the Proceeds of the sale of the related Pledged Debt Securities
held by the Collateral Agent. Such sale will be made by the Remarketing Agent
pursuant to the terms of the Remarketing Agreement and the Remarketing
Underwriting Agreement on the third Business Day immediately preceding the
Purchase Contract Settlement Date. If, as provided in the Purchase Contract
Agreement, upon the occurrence of a Failed Remarketing the Collateral Agent, for
the benefit of the Company, exercises its rights as a secured creditor with
respect to the Pledged Debt Securities related to this Normal Unit Certificate,
any accumulated and unpaid dividends on such Pledged Debt Securities will become
payable by the Company to the holder of this Normal Unit Certificate in the
manner provided for in the Purchase Contract Agreement.

         The Company shall not be obligated to issue any Common Stock in respect
of a Purchase Contract or deliver any certificates therefor to the Holder unless
it shall have received payment in full of the aggregate purchase price for the
Common Stock to be purchased thereunder in the manner herein set forth.

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall have occurred. Upon the occurrence of a Termination Event, the Company
shall give written notice to the Agent and to the Holders, at their addresses as
they appear in the Normal Unit Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Debt Security
(as defined in the Pledge Agreement) or the appropriate Applicable Ownership
Interest in the Treasury Portfolio from the Pledge. A Normal Unit shall
thereafter represent the right to receive the Debt Security or the appropriate
Applicable Ownership Interest in the Treasury Portfolio in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement.

         Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Debt Securities. Upon receipt of notice of any meeting at which holders of Debt
Securities are entitled to vote or upon the solicitation of consents, waivers or
proxies of holders of Debt Securities, the Agent shall, as soon as practicable
thereafter, mail to the Normal Unit holders a notice (a) containing such
information as is contained in the notice or solicitation, (b) stating that each
Normal Unit holder on the record date set by the Agent therefor (which, to the
extent possible, shall be the same date as the record date for determining the
holders of Debt Securities entitled to vote) shall be entitled







                                       A-7
<PAGE>

to instruct the Agent as to the exercise of the voting rights pertaining to the
Debt Securities constituting a part of such holder's Normal Units and (c)
stating the manner in which such instructions may be given. Upon the written
request of the Normal Units Holders on such record date, the Agent shall
endeavor insofar as practicable to vote or cause to be voted, in accordance with
the instructions set forth in such requests, the maximum number of Debt
Securities as to which any particular voting instructions are received. In the
absence of specific instructions from the Holder of a Normal Unit, the Agent
shall abstain from voting the Debt Security evidenced by such Normal Unit.

         Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Normal Units and the
Collateral Agent shall have such security interests rights and obligations with
respect to the Treasury Portfolio as the Holder of Normal Units and the
Collateral Agent had in respect of the Debt Securities, as the case may be,
subject to the Pledge thereof as provided in Articles II, III, IV, V and VI, of
the Pledge Agreement and any reference herein to the Debt Securities shall be
deemed to be reference to such Treasury Portfolio.

         The Normal Unit Certificates are issuable only in registered form and
in denominations of a single Normal Unit and any integral multiple thereof. The
transfer of any Normal Unit Certificate will be registered and Normal Unit
Certificates may be exchanged as provided in the Purchase Contract Agreement.
The Normal Unit Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents permitted by the Purchase
Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A holder who elects to substitute a Treasury
Security for Debt Securities or the appropriate Applicable Ownership Interest in
the Treasury Portfolio, thereby creating Stripped Units, shall be responsible
for any fees or expenses payable in connection therewith. Except as provided in
the Purchase Contract Agreement, for so long as the Purchase Contract underlying
a Normal Unit remains in effect, such Normal Unit shall not be separable into
its constituent parts, and the rights and obligations of the Holder of such
Normal Unit in respect of the Debt Security or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, and Purchase
Contract constituting such Normal Unit may be transferred and exchanged only a
Normal Unit. The holder of a Normal Unit may substitute for the Pledged Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio securing its obligation under the related Purchase Contract Treasury
Securities in an aggregate principal amount at maturity equal to the aggregate
Stated Amount of the Pledged Debt Securities or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
in the Treasury Portfolio in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement. From and after such Collateral Substitution,
the Security for which such Pledged Treasury Securities secures the Holder's
obligation under the Purchase Contract shall be referred to as a "Stripped
Unit." A Holder may make such Collateral Substitution only in integral multiples
of ___ Normal Units for ___ Stripped Units; provided, however, that if a Tax
Event Redemption has occurred and the Treasury Portfolio has become a component
of the Normal Units, a Holder may make such Collateral Substitutions only in
integral multiples of ___________ Normal Units for ___________ Stripped Units.
Such Collateral Substitution may cause the equivalent aggregate principal amount
of this Normal Unit Certificate to be increased





                                       A-8
<PAGE>

or decreased; provided, however, the equivalent aggregate principal amount of
Normal Units shall not exceed [$400,000,000]. All such adjustments to the
equivalent aggregate principal amount of this Normal Unit Certificate shall be
duly recorded by placing an appropriate notation on the Schedule attached
hereto.

         A Holder of Stripped Units may create or recreate Normal Units by
depositing with the Collateral Agent Debt Securities or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, having an aggregate
Stated Amount, in the case of such Debt Securities, or with the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, in the case of such appropriate Applicable
Ownership Interest in the Treasury Portfolio, equal to the aggregate principal
amount at maturity of the Pledged Treasury Securities comprising part of the
Stripped Units in exchange for the release of such Pledged Treasury Securities
in accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement. Any such recreation may be effected only in integral multiples of
___ Stripped Units for ___ Normal Units.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, shall immediately and automatically terminate,
without the necessity of any notice or action by any Holder, the Agent or the
Company, if, on or prior to the Purchase Contract Settlement Date, a Termination
Event shall have occurred. Upon the occurrence of a Termination Event, the
Company shall promptly but in no event later than two Business Days thereafter
give written notice to the Agent, the Collateral Agent and to the Holders, at
their addresses as they appear in the Normal Unit Register. Upon and after the
occurrence of a Termination Event, the Collateral Agent shall release the Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, from the Pledge in accordance with the provisions
of the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities having an aggregate Stated Amount equal to $1,000 or an
integral multiple thereof may be settled early ("Early Settlement") as provided
in the Purchase Contract Agreement ; provided, however, that if a Tax Event
Redemption has occurred and the Treasury Portfolio has become a component of the
Normal Units, Holders may early settle Normal Units only in integral multiples
of ___________ Normal Units. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Normal Unit
Certificate, the Holder of this Normal Unit Certificate shall deliver this
Normal Unit Certificate to the Agent at the Corporate Trust Office duly endorsed
for transfer to the Company or in blank with the form of Election to Settle
Early set forth below duly completed and accompanied by payment in the form of
immediately available funds payable to the order of the Company in an amount
(the "Early Settlement Amount") equal to (i) the product of (A) the Stated
Amount times (B) the number of Purchase Contracts with respect to which the
Holder has elected to effect Early Settlement, plus (ii) if such delivery is
made with respect to any Purchase Contracts during the period from the close of
business on any Record Date for any Payment Date to the opening of business on
such Payment Date, the interest payable on the related Debt Securities payable
on such Payment Date, if declared, with respect to such Purchase Contracts. Upon
Early Settlement of Purchase Contracts by a Holder of the related Securities,
the Pledged Debt Securities or the appropriate Applicable Ownership Interest in
the Treasury Portfolio underlying such Securities shall be released from







                                       A-9
<PAGE>


the Pledge as provided in the Pledge Agreement and the Holder shall be entitled
to receive a number of shares of Common Stock on account of each Purchase
Contract forming part of a Normal Unit as to which Early Settlement is effected
equal to the Early Settlement Rate. The Early Settlement Rate shall initially be
equal to - shares of Common Stock and shall be adjusted in the same manner and
at the same time as the Settlement Rate is adjusted as provided in the Purchase
Contract Agreement.

         Upon registration of transfer of this Normal Unit Certificate, 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 the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Normal Units
Certificate. The Company covenants and agrees, and the Holder, by its acceptance
hereof, likewise covenants and agrees, to be bound by the provisions of this
paragraph.

         The Holder of this Normal Unit Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Normal Units evidenced hereby on his behalf as his
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee, agrees to
be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Pledge Agreement on his behalf as its attorney-in-fact, and consents to the
Pledge of the Debt Securities or the appropriate Applicable Ownership Interest
in the Treasury Portfolio, as the case may be, this Normal Unit Certificate
pursuant to the Pledge Agreement. The Holder further covenants and agrees, that,
to the extent and in the manner provided in the Purchase Contract Agreement and
the Pledge Agreement, but subject to the terms thereof, payments in respect to
the Stated Amount of the Pledged Debt Securities, or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, on the Purchase Contract Settlement Date shall be
paid by the Collateral Agent to the Company in satisfaction of such Holder's
obligations under such Purchase Contract and such Holder shall acquire no right,
title or interest in such payments.

         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York, without regard
to conflicts of laws principles thereof.

         The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Normal Unit Certificate is
registered as the owner of the Normal Units evidenced hereby for the purpose of
receiving payments of interest payable quarterly on the Debt Securities, if
declared, performance of the Purchase Contracts and for all other purposes
whatsoever, whether or not any payments in respect thereof be overdue and

Agreement and more fully

                     (Reverse of Stripped Unit Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of ____ (as may be supplemented from time to time,
the"Purchase Contract Agreement") between the Company and [The Bank of New York,
a New York] banking corporation, as Purchase Contract Agent (including its
successors thereunder, herein called the "Agent"), to which the Purchase
Contract 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 Company and the Holders and
of the terms upon which the Stripped Unit Certificates are, and are to be,
executed and delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Stripped Unit Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price") a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event or an Early Settlement with
respect to the Security of which such Purchase Contract is a part. The
"Settlement Rate" is equal to (a) if the Applicable Market Value (as defined
below) is equal to or greater than $- (the "Threshold Appreciation Price"), -
shares of Common Stock per Purchase Contract, (b) if the Applicable Market Value
is less than the Threshold Appreciation Price but is greater than $- (the
"Threshold Depreciation Price"), the number of shares of Common Stock per
Purchase Contract equal to the Stated Amount divided by the Applicable Market
Value and (c) if the Applicable Market Value is less than or equal to the
Threshold Depreciation Price, - shares of Common Stock per Purchase Contract, in
each case subject to adjustment as provided in the Purchase Contract Agreement.
No fractional shares of Common Stock will be issued upon settlement of Purchase
Contracts, as provided in the Purchase Contract Agreement.

         Each Purchase Contract evidenced hereby which is settled through Early
Settlement shall obligate the Holder of the related Stripped Units to purchase
at the Purchase Price, and the Company to sell, a number of newly issued shares
of Common Stock equal to the Early Settlement Rate.

         The "Applicable Market Value" means the average of the Closing Prices
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Purchase Contract Settlement
Date.

         The "Closing Price" of the Common Stock on any date of determination
means the closing sale price (or, if no closing price is reported, the last
reported sale price) of the Common Stock on the New York Stock Exchange (the
"NYSE") on such date or, if the Common Stock is not listed for trading on the
NYSE on any such date, as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, or if the Common Stock is not so listed on a United States national or
regional securities exchange, as reported by The Nasdaq Stock Market, or, if the
Common Stock is not so reported, the last quoted bid price for the Common Stock
in the over-the-counter market as reported by the National Quotation Bureau or
similar organization, or, if such bid price is not available, the market value
of the Common Stock on such date as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company.





                                       B-5
<PAGE>


         A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Stripped Unit Certificate shall pay the Purchase Price for the
Common Stock purchased pursuant to each Purchase Contract evidenced hereby by
effecting either an Early Settlement of each such Purchase Contract or by
applying a principal amount at maturity of the Pledged Treasury Securities
underlying such Holder's Stripped Units equal to the Stated Amount of such
Purchase Contract to the purchase of the Common Stock.

         The Company shall not be obligated to issue any Common Stock in respect
of a Purchase Contract or deliver any certificates therefor to the Holder unless
it shall have received payment in full of the aggregate purchase price for the
Common Stock to be purchased thereunder in the manner herein set forth.

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall have occurred. Upon the occurrence of a Termination Event, the Company
shall give written notice to the Agent and to the Holders, at their addresses as
they appear in the Stripped Unit Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities (as defined in the Pledge Agreement) forming a part of each Stripped
Unit from the Pledge. A Stripped Unit shall thereafter represent the right to
receive the Treasury Securities forming a part of such Stripped Unit in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

         The Stripped Unit Certificates are issuable only in registered form and
only in denominations of a single Stripped Unit and any integral multiple
thereof. The transfer of any Stripped Unit Certificate will be registered and
Stripped Unit Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Stripped Unit Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Debt
Securities or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, for Pledged Treasury Securities, thereby
recreating Normal Units, shall be responsible for any fees or expenses payable
in connection therewith. Except as provided in the Purchase Contract Agreement,
for so long as the Purchase Contract underlying a Stripped Unit remains in
effect, such Stripped Unit shall not be separable into its constituent parts,
and the rights and obligations of the Holder of such Stripped Unit in respect of
the Treasury Security and the Purchase Contract constituting such Stripped Unit
may be transferred and exchanged only as a Stripped Unit. The Holder of a
Stripped Unit may substitute for the Pledged Treasury Securities securing its
obligation under the related Purchase Contract Debt Securities or the
appropriate Applicable Ownership Interest in the Treasury Portfolio, as the case
may be, with a Stated Amount, in the case of such Debt Securities, or with the
appropriate






                                       B-6
<PAGE>


Applicable Ownership Interest (as specified in clause (A) of the definition of
Ownership Interest in the Treasury Portfolio, equal to the aggregate principal
amount at maturity of the Pledged Treasury Securities in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement. From and
after such Collateral Substitution, the Security for which such Debt Securities
secures the Holder's obligation under the Purchase Contract shall be referred to
as a "Normal Unit." A Holder may make such Collateral Substitution only in
integral multiples of Stripped Units for ____ Debt Securities. Such Collateral
Substitution may cause the equivalent aggregate principal amount at maturity of
this Stripped Unit Certificate to be increased or decreased; provided, however,
the equivalent aggregate principal amount outstanding under this Stripped Unit
Certificate shall not exceed [$400,000,000]. All such adjustments to the
equivalent aggregate principal amount of this Stripped Unit Certificate shall be
duly recorded by placing an appropriate notation on the Schedule attached
hereto.

         A Holder of Normal Units may create or recreate a Stripped Unit by
delivering to the Collateral Agent Treasury Securities in an aggregate principal
amount [at maturity] equal to the aggregate Stated Amount of the Pledged Debt
Securities or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as the
case may be, in exchange for the release of such Pledged Debt Securities or the
appropriate Applicable Ownership Interest in the Treasury Portfolio, as the case
may be, in accordance with the terms of the Purchase Contract Agreement and the
Pledge Agreement. Any such recreation of a Stripped Unit may be effected only in
multiples of ___ Normal Units for ___ Stripped Units; provided, however, if a
Tax Event Redemption has occurred and the Treasury Portfolio has become a
component of the Normal Units, a Holder may make such Collateral Substitution in
integral multiples of ___________ Normal Units for _________ Stripped Units.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two business days thereafter give written notice to
the Agent, the Collateral Agent and to the Holders, at their addresses as they
appear in the Stripped Unit Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Treasury Securities
from the Pledge in accordance with the provisions of the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities having an aggregate Stated Amount equal to $1,000 or an
integral multiple thereof may be settled early ("Early Settlement") as provided
in the Purchase Contract Agreement. In order to exercise the right to effect
Early Settlement with respect to any Purchase Contracts evidenced by this
Stripped Unit Certificate, the Holder of this Stripped Unit Certificate shall
deliver this Stripped Unit Certificate to the Agent at the Corporate Trust
Office duly endorsed for transfer to the Company or in blank with the form of
Election to Settle Early set forth below duly completed and accompanied by
payment in the form of immediately available funds payable to the order of the
Company in an amount (the "Early Settlement Amount") equal to the product of (A)
the Stated Amount times (B) the number of Purchase Contracts with respect to
which the Holder has elected to effect

Early Settlement. Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, the Pledged Treasury Securities underlying such Securities
shall be released from the Pledge as provided in the Pledge Agreement and the
Holder shall be entitled to receive a number of shares of Common Stock on
account of each Purchase Contract forming part of a Stripped Unit as to which
Early Settlement is effected equal to the Early Settlement Rate. The Early
Settlement Rate shall initially be equal to - shares of Common Stock and shall
be adjusted in the same manner and at the same time as the Settlement Rate is
adjusted as provided in the Purchase Contract Agreement.

         Upon registration of transfer of this Stripped Unit Certificate, 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 the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Stripped
Unit Certificate. The Company covenants and agrees, and the Holder, by his
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

         The Holder of this Stripped Unit Certificate, by his acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Stripped Units evidenced hereby on his behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Pledge Agreement on his behalf as his attorney-in-fact, and consents to the
Pledge of the Treasury Securities underlying this Stripped Unit Certificate
pursuant to the Pledge Agreement. The Holder further covenants and agrees, that,
to the extent and in the manner provided in the Purchase Contract Agreement and
the Pledge Agreement, but subject to the terms thereof, payments in respect to
the Stated Amount of the Pledged Treasury Securities on the Purchase Contract
Settlement Date shall be paid by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York, without regard
to conflicts of laws principles thereof.

         The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Stripped Unit Certificate
is registered as the owner of the Stripped Units evidenced hereby for the
purpose of receiving payments of interest on the Treasury Securities,
performance of the Purchase Contracts and for all other purposes whatsoever,
whether or not any payments in respect thereof be overdue and notwithstanding
any notice to the contrary, and neither the Company, the Agent nor any such
agent shall be affected by notice to the contrary.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of Common Stock.
