take the relevant action with respect to the Income PRIDES or the Growth PRIDES,
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

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

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 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 its
Chief Executive Officer, its President or one of its Vice Presidents and its
Treasurer or one of its Assistant Treasurers, or its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the

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

         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

         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 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

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 Income PRIDES or Growth PRIDES 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.

<PAGE>   25




         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 Income PRIDES or Growth PRIDES, 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 Income PRIDES or Growth
PRIDES, 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
"Income PRIDES Register") in which, subject to such reasonable regulations as it
may prescribe, the Agent shall provide for the registration of Income PRIDES
Certificates and of transfers of Income PRIDES Certificates (the Agent, in such
capacity, the "Income PRIDES Registrar") and a Register (the "Growth PRIDES
Register") in which, subject to such reasonable regulations as it may prescribe,
the Agent shall provide for the registration of the Growth PRIDES Certificates
and transfers of Growth PRIDES Certificates (the Agent, in such capacity, the
"Growth PRIDES 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 Income PRIDES or Growth PRIDES, 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
Income PRIDES or Growth PRIDES, as 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 Income
PRIDES or Growth PRIDES, as the case may be, and be entitled to the same
benefits and subject to the same obligations, under this Agreement as the Income
PRIDES or Growth PRIDES, as the case may be, evidenced by the Certificate
surrendered upon such registration of transfer or exchange.

                                      -19-


<PAGE>   26




         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 shares 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 Income PRIDES, if a Termination Event shall
have occurred prior to the Purchase Contract Settlement Date, transfer the
aggregate Stated Amount of the Preferred Securities or the Treasury Portfolio,
as applicable, evidenced thereby, or (iii) in the case of Growth PRIDES, 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 Depositary if so requested by the Company. Unless and
until definitive, fully registered Certificates have been issued to Beneficial
Owners pursuant to Section 3.9:

                    (a)    the provisions of this Section 3.6 shall be in full
force and effect;

                    (b)    the Company shall be entitled to deal with the 
Clearing Agency for all purposes of this Agreement (including the payment of
Contract Adjustment Payments, if any,

                                      -20-


<PAGE>   27



and receiving approvals, votes or consents hereunder) as the Holder of the
Securities and the sole holder of the Global 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 payments of Contract Adjustment Payments, if any, 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
such notices and communications to the Holders and, with respect to any
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.


                                      -21-


<PAGE>   28



         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 Income
PRIDES or Growth PRIDES, 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 either 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 Income PRIDES or
Growth PRIDES, as the case may be, and bearing a Certificate number not
contemporaneously outstanding.

         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 to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the Purchase Contract Settlement Date (or the Early Settlement) 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
shares of Common Stock issuable in respect of the Purchase Contracts forming a
part of the Securities evidenced by such Certificate, or (ii) if a Termination
Event shall have occurred prior to the Purchase Contract Settlement Date,
transfer the Preferred Securities, the appropriate Applicable Ownership Interest
of the Treasury Portfolio or the Treasury Securities, as the case may be,
evidenced thereby, in each case subject to the applicable conditions and in
accordance with the applicable provisions of Article Five hereof.

         Upon the issuance of any new Certificate under this Section, the
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.


                                      -22-


<PAGE>   29



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

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
Income PRIDES or Growth PRIDES evidenced thereby, for the purpose of receiving
distributions on the Preferred Securities or on the maturing quarterly interest
strips of the Treasury Portfolio, as applicable, receiving payments of Contract
Adjustment Payments, if any, performance of the Purchase Contracts and for all
other purposes whatsoever, whether or not any distributions on the Preferred
Securities or the Contract Adjustment Payments, if any, payable in respect of
the Purchase Contracts constituting a part of the Income PRIDES or Growth PRIDES
evidenced thereby 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.

SECTION 3.12.  CANCELLATION.

         All Certificates surrendered for delivery of shares of Common Stock on
or after the Purchase Contract Settlement Date, upon the transfer of Preferred
Securities, the appropriate Applicable Ownership Interest of the Treasury
Portfolio or Treasury Securities, as the case may be, after the occurrence of a
Termination 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 an Income PRIDES 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 and delivered in lieu of or in exchange for any
Certificates cancelled as provided in this Section, except as expressly
permitted by this Agreement. All cancelled Certificates held by the Agent shall
upon written request be returned to the Company.


                                      -23-


<PAGE>   30



         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 GROWTH PRIDES.

         A Holder may separate the Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as applicable, from the
related Purchase Contracts in respect of an Income PRIDES by substituting for
such Preferred Securities or the appropriate Applicable Ownership Interest of
the Treasury Portfolio, as the case may be, Treasury Securities in an aggregate
principal amount equal to the aggregate Stated Amount of such Preferred
Securities or for 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 in the case of the Preferred Securities
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 of the Treasury Portfolio, in each case by (a) depositing with the
Collateral Agent Treasury Securities having an aggregate principal amount equal
to the aggregate Stated Amount of the Preferred Securities comprising part of
such Income PRIDES or for the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio comprising part of such Income PRIDES, as the case may be, and (b) (i)
by delivering cash in an amount equal to the Contract Adjustment Payments, if
any, that would have accrued since the last date that Contract Adjustment
Payments, if any, were made through the date of substitution on the Growth
PRIDES being created by the holder, which amount the Agent shall promptly remit
to the Company, and (ii) transferring the related Income PRIDES 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 Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be,
underlying such Income PRIDES, 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, Preferred Securities or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, having a
corresponding aggregate Stated Amount of such Preferred 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, 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 Income PRIDES;


                                      -24-


<PAGE>   31



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

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

         Holders who elect to separate the Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, from the related Purchase Contract and to substitute Treasury Securities
for such Preferred Securities or the appropriate Applicable Ownership Interest
of 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.

         Holders may make Collateral Substitutions (i) only in integral
multiples of 40 Income PRIDES if Preferred Securities are being substituted by
Treasury Securities, or (ii) only in integral multiples of 1,600,000 Income
PRIDES 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 Income PRIDES or fails
to deliver an Income PRIDES Certificate(s) to the Agent after depositing
Treasury Securities with the Collateral Agent, the Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, constituting a part of such Income PRIDES, and any distributions on such
Preferred Security or the Applicable Ownership Interest of 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 Income PRIDES is so
transferred or the Income PRIDES Certificate is so delivered, as the case may
be, or, with respect to an Income PRIDES Certificate, such Holder provides
evidence satisfactory to the Company and the Agent that such Income PRIDES
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 an Income PRIDES remains in effect, such Income PRIDES shall
not be separable into its constituent parts, and the rights and obligations of
the Holder in respect of the Preferred Securities or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, and Purchase
Contract comprising such Income PRIDES may be acquired, and may be transferred
and exchanged, only as an Income PRIDES.

SECTION 3.14.     ESTABLISHMENT OR REESTABLISHMENT OF INCOME PRIDES.

         A Holder of a Growth PRIDES may create or recreate Income PRIDES at any
time (i) on or prior to the fifth Business Day immediately preceding the
Purchase Contract Settlement Date, if a Tax Event Redemption has not occurred,
and (ii) on or prior to the second Business

                                      -25-


<PAGE>   32



Day immediately preceding the Purchase Contract Settlement Date, if a Tax Event
Redemption has occurred and an Applicable Ownership Interest in the Treasury
Portfolio has become a component of the Income PRIDES, in each case by (a)
depositing with the Collateral Agent Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be,
having an aggregate Stated Amount in the case of the Preferred Securities, or an
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 of the Treasury Securities comprising part of the
Growth PRIDES and (b) transferring the related Growth PRIDES 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 Preferred
Securities or the appropriate Applicable Ownership Interest of 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 Growth PRIDES, whereupon the Agent shall promptly give such
instruction to the Collateral Agent, substantially in the form of Exhibit C
hereto. Upon receipt of the Preferred Securities or the appropriate Applicable
Ownership Interest of 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 from the Pledge to the Agent free and clear of the Company's
security interest therein, and upon receipt thereof the Agent shall promptly:

               (i)    cancel the related Growth PRIDES;

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

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

         Holders of Growth PRIDES may establish or reestablish Income PRIDES in
integral multiples of 40 Growth PRIDES for 40 Income PRIDES if a Tax Event
Redemption has not occurred, and in integral multiples of 1,600,000 Growth
PRIDES for 1,600,000 Income PRIDES if a Tax Event Redemption has occurred.

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

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 Preferred Securities, the appropriate Applicable Ownership Interest
of the Treasury Portfolio or the Treasury Securities, as the case may be,
underlying the Income PRIDES and the Growth PRIDES pursuant to the terms of the
Pledge Agreement, the Agent shall request transfer instructions with respect to
such Preferred Securities or the appropriate Applicable Ownership Interest of
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 Income PRIDES Register or the Growth PRIDES Register, as the case may be.
Upon book-entry transfer of the Income PRIDES or Growth PRIDES or delivery of an
Income PRIDES Certificate or Growth PRIDES Certificate to the Agent with such
transfer instructions, the Agent shall transfer the Preferred Securities, the
Treasury Portfolio or Treasury Securities, as the case may be, underlying such
Income PRIDES or Growth PRIDES, 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 Income PRIDES or Growth PRIDES fails to effect such
transfer or delivery, the Preferred Securities, the appropriate Applicable
Ownership Interest of the Treasury Portfolio or Treasury Securities, as the case
may be, underlying such Income PRIDES or Growth PRIDES, 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 Income PRIDES or Growth
PRIDES are transferred or the Income PRIDES Certificate or Growth PRIDES
Certificate is surrendered or such Holder provides satisfactory evidence that
such Income PRIDES Certificate or Growth PRIDES Certificate has been destroyed,
lost or stolen, together with any indemnity that may be required by the Agent
and the Company.

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, a
receiver, a liquidator or a person or entity performing similar functions, or
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.

                                   ARTICLE IV

                            THE PREFERRED SECURITIES

SECTION 4.1.   PAYMENT OF DISTRIBUTION; RIGHTS TO DISTRIBUTIONS PRESERVED; 
               DISTRIBUTION RATE RESET; NOTICE.

         A distribution on any Preferred Security or on 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

                                      -27-


<PAGE>   34



the Pledge Agreement, be paid to the Person in whose name the Income PRIDES
Certificate (or one or more Predecessor Income PRIDES Certificates) of which
such Preferred Security or the appropriate Applicable Ownership Interest of 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 Income PRIDES Certificate evidencing Preferred Securities
delivered under this Agreement upon registration of transfer of or in exchange
for or in lieu of any other Income PRIDES Certificate shall carry the rights to
distributions accrued and unpaid, and to accrue distributions, which were
carried by the Preferred Securities underlying such other Income PRIDES
Certificate.

         In the case of any Income PRIDES 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, distributions on the
Preferred Securities or on the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, underlying such Income PRIDES 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 distributions shall, subject to receipt thereof by the
Agent, be payable to the Person in whose name the Income PRIDES Certificate (or
one or more Predecessor Income PRIDES 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 Income PRIDES 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, distributions on the
related Preferred Securities or on the appropriate Applicable Ownership Interest
of 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 Income PRIDES; provided, however,
that to the extent that such Holder continues to hold the separated Preferred
Securities that formerly comprised a part of such Holder's Income PRIDES, such
Holder shall be entitled to receive the distributions on such separated
Preferred Securities.

         The applicable Coupon Rate on the Preferred 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 Two-Year
Benchmark Treasury 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 Preferred Securities Holders will be notified of such Reset Spread and
Two-Year Benchmark Treasury by the Company. Such notice shall be sufficiently
given to Holders of Preferred Securities if published in an Authorized Newspaper
in The City of New York.

                                      -28-


<PAGE>   35




         Not later than 7 calendar days nor more than 15 calendar days prior to
the Reset Announcement Date, the Company will notify the 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
Income PRIDES or Growth PRIDES, of such Reset Announcement Date and the
procedures to be followed by such Holders of Income PRIDES 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 Preferred
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 Preferred Securities are entitled to vote or upon any
solicitation of consents, waivers or proxies of holders of Preferred Securities,
the Agent shall, as soon as practicable thereafter, mail to the Holders of
Income PRIDES 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 Preferred Securities entitled to
vote) shall be entitled to instruct the Agent as to the exercise of the voting
rights pertaining to the Preferred Securities underlying their Income PRIDES and
(c) stating the manner in which such instructions may be given. Upon the written
request of the Holders of Income PRIDES 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 Preferred
Securities as to which any particular voting instructions are received. In the
absence of specific instructions from the Holder of an Income PRIDES, the Agent
shall abstain from voting the Preferred Security underlying such Income PRIDES.
The Company hereby agrees, if applicable, to solicit Holders of Income PRIDES to
timely instruct the Agent in order to enable the Agent to vote such Preferred
Securities and the Trust shall covenant to such effect in the Trust Agreement.

SECTION 4.3.   DISTRIBUTION OF DEBENTURES; TAX EVENT REDEMPTION.

         Upon the occurrence of an Investment Company Event or a liquidation of
the Trust in accordance with the Trust Agreement, a principal amount of
Debentures constituting the assets of the Trust and underlying the Preferred
Securities equal to the aggregate Stated Amount of the Pledged Preferred
Securities shall be delivered to the Collateral Agent in exchange for the
Pledged Preferred Securities. Thereafter, the Debentures will be substituted for
the Pledged Preferred Securities, and will be held by the Collateral Agent in
accordance with the terms of the Pledge Agreement to secure the obligations of
each Holder of an Income PRIDES to purchase the Common Stock of the Company
under the Purchase Contracts constituting a part of such Income PRIDES.
Following the occurrence of an Investment Company Event or a liquidation of the
Trust, the Holders and the Collateral Agent shall have such security interests,

                                      -29-


<PAGE>   36



rights and obligations with respect to the Debentures as the Holders and the
Collateral Agent had in respect of the Preferred Securities 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 Preferred Securities shall be deemed
to be a reference to such Debentures. The Company may cause to be made in any
Income PRIDES Certificates 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 Debentures for Preferred Securities as
Collateral.

       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 Debentures
shall be delivered to the Collateral Agent in exchange for the Pledged Preferred
Securities. Thereafter, 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 Income PRIDES the
Treasury Portfolio and promptly remit the remaining portion of such Redemption
Price to the Agent for payment to the Holders of such Income PRIDES. The
Treasury Portfolio will be substituted for the Pledged Preferred 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 an Income PRIDES to
purchase the Common Stock of the Company under the Purchase Contract
constituting a part of such Income PRIDES. Following the occurrence of a Tax
Event Redemption prior to the Purchase Contract Settlement Date, the Holders of
Income PRIDES and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Treasury Portfolio as the Holder of
Income PRIDES and the Collateral Agent had in respect of the Preferred Security
or Debentures, 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 Preferred Security or the Debenture shall be deemed to be
reference to such Treasury Portfolio. The Company may cause to be made in any
Income PRIDES Certificates 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 Preferred
Securities or Debentures as collateral.

                                    ARTICLE V

                             THE PURCHASE CONTRACTS

SECTION 5.1.   PURCHASE OF SHARES OF COMMON STOCK.

         Each Purchase Contract shall, unless an Early Settlement has occurred
in accordance with Section 5.9 hereof, obligate the Holder of the related
Security to purchase, and the Company to sell, not later than 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 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

                                      -30-


<PAGE>   37



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 "Reference Price"), the number of shares 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 the Reference Price, ____ shares of Common
Stock per Purchase Contract, in each case subject to adjustment as provided in
Section 5.6 (and in each case rounded upward or downward to the nearest
1/10,000th of a share). As provided in Section 5.10, no fractional shares of
Common Stock will be issued upon settlement of Purchase Contracts.

         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, Inc. (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, 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
"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.

         Each Holder of an Income PRIDES or a Growth PRIDES, 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 Preferred 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 an Income PRIDES or a Growth PRIDES, by its
acceptance thereof, further covenants and agrees, that, to the extent and in the
manner provided in Section 5.4 and the Pledge Agreement, but subject to the
terms thereof, payments in respect of the Stated Amount of the Preferred
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

                                      -31-


<PAGE>   38



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.   CONTRACT ADJUSTMENT PAYMENTS.

         Subject to Section 5.3 herein, the Company shall pay, on each Payment
Date, the Contract Adjustment Payments, if any, payable in respect of each
Purchase Contract to the Person in whose name an Income PRIDES Certificate or a
Growth PRIDES Certificate (or one or more Predecessor Certificates) is
registered at the close of business on the Record Date next preceding such
Payment Date. The Contract Adjustment Payments, if any, will be payable at the
office of the Agent in The City of New York maintained for that purpose or, at
the option of the Company, by check mailed to the address of the Person entitled
thereto at such Person's address as it appears on the Income PRIDES Register or
the Growth PRIDES Register.

         Upon the occurrence of a Termination Event, the Company's obligation to
pay Contract Adjustment Payments, if any, (including any accrued or Deferred
Contract Adjustment Payments) shall cease.

         Each Certificate delivered under this Agreement upon registration of
transfer of or in exchange for or in lieu of (including as a result of a
Collateral Substitution or the re-establishment of an Income PRIDES) any other
Certificate shall carry the rights to Contract Adjustment Payments, if any,
accrued and unpaid, and to accrue Contract Adjustment Payments, if any, which
were carried by the Purchase Contracts underlying such other Certificates.

         Subject to Section 5.9, in the case of any Security with respect to
which Early Settlement of the underlying Purchase Contract is effected on an
Early Settlement Date that is after any Record Date and on or prior to the next
succeeding Payment Date, Contract Adjustment Payments, if any, otherwise payable
on such Payment Date shall be payable on such Payment Date notwithstanding such
Early Settlement, and such Contract Adjustment Payments, if any, shall be paid
to the Person in whose name the Certificate evidencing such Security (or one or
more Predecessor Certificates) is registered at the close of business on such
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security with respect to which Early Settlement of
the underlying Purchase Contract is effected on an Early Settlement Date,
Contract Adjustment Payments, if any, that would otherwise be payable after the
Early Settlement Date with respect to such Purchase Contract shall not be
payable.

                                      -32-


<PAGE>   39




         The Company's obligations with respect to Contract Adjustment Payments,
if any, will be subordinated and junior in right of payment to the Company's
obligations under any Senior Indebtedness.

SECTION 5.3.   DEFERRAL OF PAYMENT DATES FOR CONTRACT ADJUSTMENT PAYMENTS.

         The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) at least ten
Business Days prior to the earlier of (i) the next succeeding Payment Date or
(ii) the date the Company is required to give notice of the Record Date or
Payment Date with respect to payment of such Contract Adjustment Payments, if
any, to the NYSE or other applicable self-regulatory organization or to Holders
of the Securities, but in any event not less than one Business Day prior to such
Record Date. Any Contract Adjustment Payments, if any, so deferred shall bear
additional Contract Adjustment Payments thereon at the rate of ____% per annum
(computed on the basis of a 360 day year of twelve 30 day months), compounding
on each succeeding Payment Date, until paid in full (such deferred installments
of Contract Adjustment Payments, if any, together with the additional Contract
Adjustment Payments accrued thereon, being referred to herein as the "Deferred
Contract Adjustment Payments"). Deferred Contract Adjustment Payments shall be
due on the next succeeding Payment Date except to the extent that payment is
deferred pursuant to this Section. No Contract Adjustment Payments, if any, may
be deferred to a date that is after the Purchase Contract Settlement Date. If
the Purchase Contracts are terminated upon the occurrence of a Termination
Event, the Holder's right to receive Contract Adjustment Payments, if any, and
Deferred Contract Adjustment Payments will terminate.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until the Purchase
Contract Settlement Date, each Holder will receive on the Purchase Contract
Settlement Date in lieu of a cash payment a number of shares of Common Stock (in
addition to a number of shares of Common Stock equal to the Settlement Rate)
equal to (x) the aggregate amount of Deferred Contract Adjustment Payments
payable to such Holder divided by (y) the Applicable Market Value.

         No fractional shares of Common Stock will be issued by the Company with
respect to the payment of Deferred Contract Adjustment Payments on the Purchase
Contract Settlement Date. In lieu of fractional shares otherwise issuable with
respect to such payment of Deferred Contract Adjustment Payments, the Holder
will be entitled to receive an amount in cash as provided in Section 5.10.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then, until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or

                                      -33-


<PAGE>   40



redeem, purchase or acquire, or make a liquidation payment with respect to, any
of its capital stock or make guarantee payments with respect to the foregoing
(other than (i) purchases or acquisitions of shares of capital stock of the
Company in connection with the satisfaction by the Company of its obligations
under any employee benefit plans or the satisfaction by the Company of its
obligations pursuant to any contract or security outstanding on the date of such
event requiring the Company to purchase capital stock of the Company, (ii) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (iii) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged, (iv) dividends or distributions in capital stock of the Company (or
rights to acquire capital stock) or repurchases or redemptions of capital stock
solely from the issuance or exchange of capital stock or (v) redemptions or
repurchases of any rights outstanding under a shareholder rights plan or the
declaration thereunder of a dividend of rights in the future).

SECTION 5.4.   PAYMENT OF PURCHASE PRICE.

         (a)(i) Unless a Tax Event Redemption has occurred or a Holder settles
the underlying Purchase Contract through the early delivery of cash to the
Purchase Contract Agent in the manner described in Section 5.9, each Holder of
an Income PRIDES 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 shares of 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 an Income PRIDES 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 an Income PRIDES 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 Preferred Securities
pursuant to the Remarketing as described in paragraph (b) below. If a Holder of
an Income PRIDES does notify the Agent as provided in paragraph (a)(i) above

                                      -34-


<PAGE>   41



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 Preferred 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
Preferred Securities, including those rights specified in paragraph (c) below.

         (b)    In order to dispose of the Preferred Securities (or Debentures
exchanged for Preferred Securities following an Investment Company Event or
other dissolution of the Trust) of Income PRIDES 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 Preferred Securities (or Debentures). 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 Preferred Securities (or
Debentures) to be remarketed. Concurrently, the Collateral Agent, pursuant to
the terms of the Pledge Agreement, will present for remarketing such Preferred
Securities (or Debentures) to the Remarketing Agent. Upon receipt of such notice
from the Agent and such Preferred Securities (or Debentures) 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 Preferred Securities (or Debentures) on such date at a price of
approximately 100.50% (but not less than 100%) of the aggregate stated
liquidation amount of such Preferred Securities (or Debentures), plus accrued
and unpaid distributions (including deferred distributions), if any, thereon.
After deducting as the remarketing fee ("Remarketing Fee") an amount not
exceeding 25 basis points (.25%) of the aggregate stated liquidation amount of
the remarketed Preferred Securities (or Debentures) from any amount of such
proceeds in excess of the aggregate stated liquidation amount of the remarketed
Preferred Securities (or Debentures) plus accrued and unpaid distributions
(including any deferred distributions), 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 stated liquidation
amount of such Preferred Securities (or Debentures) will automatically be
applied by the Collateral Agent, in accordance with the Pledge Agreement to
satisfy in full such Income PRIDES 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 Income PRIDES. Income PRIDES Holders whose
Preferred Securities (or Debentures) 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 Preferred Securities (or Debentures) of such Holders of Income
PRIDES at a price not less than 100% of the aggregate stated liquidation amount
of such Preferred Securities (or Debentures) plus accrued and unpaid
distributions (including deferred distributions), 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
Preferred Securities (or Debentures), including those

                                      -35-

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 Preferred Securities (or Debentures), any accrued
and unpaid distributions (including any deferred distributions) on such
Preferred Securities (or Debentures) will become payable by the Company to the
Agent for payment to the Holder of the Income PRIDES to which such Preferred
Securities (or Debentures) 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 a daily newspaper in the English language of general
circulation in The City of New York, which is expected to be The Wall Street
Journal.

         (c)    With respect to any Preferred 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 Preferred Securities which are subject to a
Failed Remarketing, the Collateral Agent for the benefit of the Company reserves
all of its rights as a secured party with respect thereto and, subject to
applicable law and paragraph (h) below, may, among other things, (i) retain the
Preferred Securities in full satisfaction of the Holders' obligations under the
Purchase Contracts or (ii) sell the Preferred Securities in one or more public
or private sales.

         (d)   (i)   Unless a Holder of Growth PRIDES or Income PRIDES (if a Tax
         Event Redemption has occurred) settles the underlying Purchase Contract
         through the early delivery of cash to the Purchase Contract Agent in
         the manner described in Section 5.9, each Holder of a Growth PRIDES or
         Income PRIDES (if a Tax Event Redemption has occurred) 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 shares of
         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 Growth PRIDES or Income PRIDES (if a Tax
         Event Redemption has occurred) 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 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 Growth PRIDES or an Income PRIDES (if a
         Tax Event Redemption has occurred) fails to notify the Agent of its
         intention to make a Cash Settlement in accordance with paragraph (d)(i)
         above, or if a Holder of a Growth PRIDES or an Income PRIDES (if a Tax
         Event Redemption has occurred) does notify the Agent as provided in
         paragraph (d)(i) above its intention to pay the Purchase Price in cash,
         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 of 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 of the Treasury Securities or the appropriate
         Applicable Ownership Interest of the Treasury Portfolio, as the case
         may be, received by the Collateral Agent will be invested promptly in
         overnight Permitted Investments. 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 of
         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 Growth PRIDES or Income PRIDES when received.

         (d)    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.

         (e)    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 shares of 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 shares of Common Stock to be purchased thereunder in the manner herein set
forth.

         (f)    Upon Cash Settlement of any Purchase Contract, (i) the 
Collateral Agent will in accordance with the terms of the Pledge Agreement cause
the Pledged Preferred Securities or the appropriate Applicable Ownership
Interest of 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
Preferred Securities or the appropriate Applicable Ownership Interest of 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 Preferred Securities or the

                                      -37-


<PAGE>   44



Treasury Portfolio, as the case may be, or such Treasury Securities, and any
distribution 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 5.5.    ISSUANCE OF SHARES OF COMMON STOCK.

         Unless a Termination Event 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 shares of Common Stock purchased by the Holders
pursuant to the foregoing provisions of this Article and subject to Section
5.6(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 shares of Common Stock registered in the name of the Agent (or its nominee)
as custodian for the Holders (such certificates for shares of Common Stock,
together with any dividends or distributions for which both 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 5.10 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 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 5.6.   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 stockholders 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 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 issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on
shares of 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 stockholders
entitled to receive such rights, options or warrants, to subscribe for or
purchase shares of Common Stock at a price per share less than the Current
Market Price per share of the Common Stock on the date fixed for the
determination of stockholders 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 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
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
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 issued in lieu of fractions of shares of
Common Stock. The Company shall not issue any such rights, options or warrants
in respect of shares of Common Stock held in the treasury of the Company.


                                      -39-


<PAGE>   46



               (3)    In case outstanding shares of 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 shares of 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 stockholders
entitled to receive such distribution by a fraction of which the numerator shall
be the Current Market Price per share of the 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 shall be such Current Market Price per share of the 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 stockholders
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 (i) regular
quarterly cash distributions, (ii) any cash that is distributed in a
Reorganization Event to which Section 5.6(b) applies or (iii) cash that is
distributed 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 (other than
regular quarterly cash distributions) 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 (other than consideration payable in
respect of any odd-lot tender 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 15% of the product of the
Current Market Price per share of the Common Stock on the date for the
determination of holders of shares of Common Stock entitled to receive such

                                      -40-


<PAGE>   47



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 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 the
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
the 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 stockholders (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 (other
than consideration payable in respect of any odd-lot tender 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 (other than regular quarterly cash 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 15% of the product of the Current Market
Price per share of the 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 the 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 stockholders 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

                                      -41-


<PAGE>   48



which shall be equal to the product of (A) the Current Market Price per share of
the 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 5.6(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 5.6(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 of which the numerator shall be the Settlement Rate immediately after
such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10)
of this Section 5.6(a) and the denominator 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),

                                      -42-


<PAGE>   49


(4), (5), (7) or (10) of this Section 5.6(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 shares
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.

         (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 (except as otherwise
specifically provided, without any interest thereon, and without any right to
dividends or distributions thereon which have a record date that is prior to
the Purchase Contract Settlement Date) by a Holder of the number of shares 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 its 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). If all or a
portion of the consideration payable to the Holders of Common Stock in a
Reorganization Event is cash, the Settlement Rate shall be further adjusted to
provide that each Holder of Securities will receive on such Purchase Contract
Settlement Date with respect to each Purchase Contract

                                      -43-

forming a part thereof an amount equal to interest that could otherwise accrue
on such cash, such interest to accumulate and compound quarterly from the date
the Reorganization Event is consummated to the Purchase Contract Settlement Date
(or, in the case of an Early Settlement, the date of Early Settlement) at ___%
per annum (as defined in the Trust Agreement). 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 5.7.   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 5.6 and prepare and transmit to the Agent an Officer's Certificate
setting forth the Settlement 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 5.6
(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
shares 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 shares of
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 5.8.   TERMINATION EVENT; NOTICE.

         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, if any, or Deferred Contract Adjustment Payments, if the Company shall
have such obligation, and 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 Preferred
Securities or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, forming a part of such Securities in the case of
Income PRIDES, or Treasury Securities in the case of Growth PRIDES, 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 5.9.   EARLY SETTLEMENT.

         (a)   Subject to and upon compliance with the provisions of this 
Section 5.9, 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 Income
PRIDES (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 Growth PRIDES 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 Income PRIDES, Purchase
Contracts underlying Income PRIDES may be settled early, on or prior to the
second Business Day immediately preceding the Purchase Contract Settlement Date,
but only in an aggregate amount of $[4,000,000] 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) 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 (x) the Contract Adjustment Payments, if
any, payable on such Payment Date with respect to such Purchase Contracts plus
(y) in the case of Income PRIDES Certificate, the distributions on the related
Preferred Securities payable on such Payment Date. Except as provided in the
immediately preceding sentence and subject to the second to last paragraph of
Section 5.2, no payment or adjustment shall be made upon Early Settlement of any
Purchase Contract on account of any

                                      -45-


<PAGE>   52



Contract Adjustment Payments, if any, accrued on such Purchase Contract or on
account of any dividends on the Common Stock issued upon such Early Settlement
or on account of any Deferred Contract Adjustment Payments. 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 and payment of any transfer or similar taxes payable by such
Holder in connection with the issuance of the related Common Stock to any person
other than such Holder, 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");
provided, however, that upon the Early Settlement of the Purchase Contracts, the
Holder of such related Securities will forfeit the right to receive any Deferred
Contract Adjustment Payments and future Contract Adjustment Payments, if any.
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 5.9, 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 5.10.

         (c)    No later than the third Business Day after the applicable Early
Settlement Date the Company shall cause (i) the shares of Common Stock issuable
upon Early Settlement of Purchase Contracts to be issued and delivered, and (ii)
the related Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, in the case of Income PRIDES, or the related
Treasury Securities, in the case of Growth PRIDES, 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 shares of Common Stock from the Company and the Preferred Securities,
the appropriate Applicable Ownership Interest of 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 Preferred Securities, Treasury Portfolio or Treasury Securities, as the case
may be, forming a part of such Securities, and (ii) deliver to the Holder 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 5.10.

<PAGE>   53



         (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 5.10.   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 share 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 5.10 in a timely manner.

SECTION 5.11.   CHARGES AND TAXES.

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the shares of Common Stock pursuant to
the Purchase Contracts and in payment of any Deferred Contract Adjustment
Payments; 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.

SECTION 6.1.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE CONTRACT ADJUSTMENT 
               PAYMENTS AND TO PURCHASE COMMON STOCK.

component of Income PRIDES or Growth PRIDES, the Holder of any Income PRIDES or
Growth PRIDES shall have the right, which is absolute and unconditional (subject
to the right of the Company to defer payment thereof pursuant to Section 5.3,
the prepayment of Contract Adjustment Payments, if any, pursuant to Section
5.9(a) and to the forfeiture of any Deferred Contract Adjustment Payments upon
Early Settlement pursuant to Section 5.9(b) or upon the occurrence of a
Termination Event), to receive payment of each installment of the Contract
Adjustment Payments, if any, with respect to the Purchase Contract constituting
a part of such Security on the respective Payment Date for such Security and to

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

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 Income PRIDES
or Growth PRIDES, by its acceptance of such Income PRIDES or Growth PRIDES 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, 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 distributions on any Preferred Securities
or Contract Adjustment Payments, if any, on any Purchase Contract 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 shares of 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.

         determine whether or not they conform to the requirements of this
         Agreement.

         (b)    No provision of this Agreement shall be construed to relieve the

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

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

thereupon the resignation or removal of the retiring Agent shall become

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.

other Person or sell, assign, transfer, lease or convey all or substantially all
of its properties and assets to any Person or group of affiliated Persons in one
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 be a corporation organized and existing under the laws of the
United States of America or a State thereof or the District of Columbia and such
corporation shall expressly assume all the obligations of the Company under the
Purchase Contracts, the Subordinated Debentures, this Agreement, the Pledge
Agreement, the Subordinated Indenture (including any supplemental indenture
thereto) and the Remarketing 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 consolidation, or such sale, assignment,
transfer, lease or conveyance, be in default of its payment obligations
thereunder or in material default in the performance of any of its obligations
thereunder.

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

                                      -58-


<PAGE>   65



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 Lincoln National Corporation 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 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 hereunder
to the consummation of any such consolidation, merger, sale, assignment,
transfer, lease or conveyance have been met.

such required office or agency or shall fail to furnish the Agent with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office, and the Company hereby appoints the
Agent as its agent to receive all 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

and of any change in the location of any such other office or agency. The

authorized, validly issued, fully paid and nonassessable.

if any, will be payable at the office of the Agent in The City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto as such address appears on the Income PRIDES Register.

         Reference is hereby made to the further provisions set forth on the
reverse hereof, which further provisions shall for all purposes have the same
effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Agent by manual signature, this Income PRIDES Certificate shall not be
entitled to any benefit under the Pledge Agreement or the Purchase Contract
Agreement or be valid or obligatory for any purpose.

                 (Form of Reverse of Income PRIDES Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of _____, 1998 (as it may be supplemented from time
to time, the "Purchase Contract Agreement"), between the Company and The First
National Bank of Chicago, as Purchase Contract Agent (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 Income
PRIDES Certificates are, and are to be, executed and delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Income PRIDES Certificate to purchase, and the Company to sell, not later than
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 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
Reference 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 Amount is less than or equal to $____, ____ 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
Income PRIDES to purchase at the Purchase Price, and the Company to sell, a
number of 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 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, Inc.
(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 National Market, or, if
the Common Stock is not

                                      -66-


<PAGE>   73



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 "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 Income PRIDES Certificate shall pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Purchase Contract evidenced
hereby by effecting a Cash Settlement, an Early Settlement or from the proceeds
of a remarketing of the related Pledged Preferred Securities of such holders. A
Holder of Income PRIDES 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 shares of Common Stock to be issued under
the related Purchase Contract from the Proceeds of the sale of the related
Pledged Preferred 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 Preferred Securities related to this Income
PRIDES certificate, any accrued and unpaid distributions (including deferred
distributions) on such Pledged Preferred Securities will become payable by the
Company to the holder of this Income PRIDES Certificate in the manner provided
for in the Purchase Contract Agreement.

         The Company shall not be obligated to issue any shares of 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 shares of 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 Income PRIDES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Security (as defined in the Pledge Agreement) or the appropriate Applicable
Ownership Interest of the Treasury Portfolio forming a part of each Income
PRIDES, or the Liquidation Distribution received in respect of such Pledged
Preferred Security, from the Pledge. An Income PRIDES shall thereafter represent
the right to receive the Preferred Security or the appropriate Applicable
Ownership Interest of the Treasury Portfolio forming a part of such Income
PRIDES, or the

                                      -67-


<PAGE>   74



Liquidation Distribution received in respect of such Preferred Security, 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
Preferred Securities. Upon receipt of notice of any meeting at which holders of
Preferred Securities are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Securities, the Agent shall, as soon
as practicable thereafter, mail to the Income PRIDES holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Income PRIDES 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 Preferred Securities entitled to vote) shall
be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Preferred Securities constituting a part of such holder's
Income PRIDES and (c) stating the manner in which such instructions may be
given. Upon the written request of the Income PRIDES 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 Preferred Securities as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of an Income PRIDES, the Agent shall abstain from voting the Preferred
Security evidenced by such Income PRIDES.

         Upon the occurrence of an Investment Company Event or liquidation of
the Trust, a principal amount of the Debentures constituting the assets of the
Trust and underlying the Preferred Securities equal to the aggregate Stated
Amount of the Pledged Preferred Securities shall be delivered to the Collateral
Agent in exchange for Pledged Preferred Securities. Thereafter, the Debentures
shall be held by the Collateral Agent to secure the obligations of each Holder
of Income PRIDES to purchase shares of Common Stock under the Purchase Contracts
constituting a part of such Income PRIDES. Following the liquidation of the
Trust, the Holders and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Debentures as the Holders and the
Collateral Agent had in respect of the Pledged Preferred Securities, and any
reference in the Purchase Contract Agreement or Pledge Agreement to the
Preferred Securities shall be deemed to be a reference to the Debentures.

         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 Debentures
shall be delivered to the Collateral Agent in exchange for the Pledged Preferred
Securities. Thereafter, pursuant to the terms of the Pledge Agreement, the
Collateral Agent for the benefit of the Company will apply an amount equal to
the Redemption Amount of such Redemption Price to purchase the Treasury
Portfolio and promptly remit the remaining portion of such Redemption Price to
the Agent for payment to the Holders of such Income PRIDES.

         Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Income PRIDES and the
Collateral Agent shall have such

                                      -68-


<PAGE>   75



security interests rights and obligations with respect to the Treasury Portfolio
as the Holder of Income PRIDES and the Collateral Agent had in respect of the
Preferred Security or Debentures, 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 Preferred Security or the Debenture shall be
deemed to be a reference to such Treasury Portfolio.

         The Income PRIDES Certificates are issuable only in registered form and
only in denominations of a single Income PRIDES and any integral multiple
thereof. The transfer of any Income PRIDES Certificate will be registered and
Income PRIDES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Income PRIDES 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 Treasury
Securities for Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, thereby creating Growth PRIDES, 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 an Income PRIDES remains in effect, such Income PRIDES shall
not be separable into its constituent parts, and the rights and obligations of
the Holder of such Income PRIDES in respect of Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, and Purchase Contract constituting such Income PRIDES may be transferred
and exchanged only as an Income PRIDES. The holder of an Income PRIDES may
substitute for the Pledged Preferred Securities or the appropriate Applicable
Ownership Interest of the Treasury Portfolio securing its obligation under the
related Purchase Contract, Treasury Securities in an aggregate principal amount
equal to the aggregate Stated Amount of the Pledged Preferred 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 "Growth PRIDES." A Holder may make such Collateral Substitution only in
integral multiples of 40 Income PRIDES for 40 Growth PRIDES; provided, however,
that if a Tax Event Redemption has occurred and the Treasury Portfolio has
become a component of the Income PRIDES, a Holder may make such Collateral
Substitutions only in integral multiples of 1,600,000 Income PRIDES for
1,600,000 Growth PRIDES. Such Collateral Substitution may cause the equivalent
aggregate principal amount of this Certificate to be increased or decreased;
provided, however, the equivalent aggregate principal amount outstanding under
this Income PRIDES Certificate shall not exceed $_____________. All such
adjustments to the equivalent aggregate principal amount of this Income PRIDES
Certificate shall be duly recorded by placing an appropriate notation on the
Schedule attached hereto.

         A Holder of Growth PRIDES may create or recreate Income PRIDES by
delivering to the Collateral Agent Preferred Securities or the appropriate
Applicable Ownership Interest of the

                                      -69-


<PAGE>   76



Treasury Portfolio, with a Stated Amount, in the case of such Preferred
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 of the Treasury
Portfolio, equal to the aggregate principal amount of the Pledged Treasury
Securities in exchange for the release of such Pledged Treasury Securities in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

         Subject to the next succeeding paragraph, the Company shall pay, on
each Payment Date, the Contract Adjustment Payments, if any, payable in respect
of each Purchase Contract to the Person in whose name the Income PRIDES
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the office of the Agent in The City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Income PRIDES Register.

         The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) as provided in the
Purchase Contract Agreement. Any Contract Adjustment Payments, if any, so
deferred shall bear additional Contract Adjustment Payments thereon at the rate
of ____% per annum (computed on the basis of a 360 day year of twelve 30 day
months), compounding on each succeeding Payment Date, until paid in full (such
deferred installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments accrued thereon, are referred to herein
as the "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment
Payments, if any, shall be due on the next succeeding Payment Date except to the
extent that payment is deferred pursuant to the Purchase Contract Agreement. No
Contract Adjustment Payments, if any, may be deferred to a date that is after
the Purchase Contract Settlement Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until the Purchase Contract
Settlement Date, the Holder of this Income PRIDES Certificate will receive on
the Purchase Contract Settlement Date, in lieu of a cash payment, a number of
shares of Common Stock equal to (x) the aggregate amount of Deferred Contract
Adjustment Payments payable to the Holder of this Income PRIDES Certificate
divided by (y) the Applicable Market Value.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
or make guarantee payments with respect to the foregoing (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its

                                      -70-


<PAGE>   77



obligations pursuant to any contract or security outstanding on the date of such
event requiring the Company to purchase capital stock of the Company, (ii) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (iii) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged, (iv) dividends or distributions in capital stock of the Company (or
rights to acquire capital stock) or repurchases or redemptions of capital stock
solely from the issuance or exchange of capital stock or (v) redemptions or
repurchases of any rights outstanding under a shareholder rights plan or a
declaration thereunder of a dividend of rights in the future).

         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 any Contract
Adjustment Payments, if any, or any Deferred 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
Income PRIDES Register. Upon and after the occurrence of a Termination Event,
the Collateral Agent shall release the Preferred Securities or the appropriate
Applicable Ownership Interest of 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
Income PRIDES, Holders may early settle Income PRIDES only in integral multiples
of 1,600,000 Income PRIDES. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Income
PRIDES Certificate, the Holder of this Income PRIDES Certificate shall deliver
this Income PRIDES 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, an amount equal to the Contract Adjustment Payments, if any,
payable on such Payment Date with respect to such Purchase Contracts. Upon Early
Settlement of Purchase Contracts by a Holder of the related Securities, the
Pledged Preferred Securities or the appropriate Applicable Ownership Interest of
the Treasury Portfolio underlying such Securities

                                      -71-


<PAGE>   78



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 Income PRIDES as to which
Early Settlement is effected equal to the Early Settlement Rate; provided
however, that upon the Early Settlement of the Purchase Contracts, the Holder
thereof will forfeit the right to receive any Deferred Contract Adjustment
Payments and future Contract Adjustment Payments on such Purchase Contracts. 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 Income PRIDES 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 Income
PRIDES 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 Income PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Income PRIDES 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 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 its behalf as its attorney-in-fact, and consents to the
Pledge of the Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as the case may be, underlying this Income
PRIDES 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 Preferred
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.

                               ___% Growth PRIDES

         This Growth PRIDES Certificate certifies that __________ is the
registered Holder of the number of Growth PRIDES set forth above. Each Growth
PRIDES represents (i) a 1/40 undivided beneficial ownership interest, of a
Treasury Security having a principal amount at maturity equal to $1,000, subject
to the Pledge of such Treasury Security by such Holder pursuant to the Pledge
Agreement, and (ii) the rights and obligations of the Holder under one Purchase
Contract with Lincoln National Corporation, an Indiana corporation (the
"Company"). All capitalized terms used herein which are defined in the Purchase
Contract Agreement have the meanings set forth therein.

         Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Growth PRIDES evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder
under the Purchase Contract comprising a portion of such Growth PRIDES.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company, to sell, not later than
_______________, 2001 (the "Purchase Contract Settlement Date"), at a price
equal to $25 (the "Stated Amount"), a number of shares of Common stock, no par
value per share ("Common Stock"), of the Company equal

                                      -78-

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 Growth PRIDES of which such Purchase Contract is a part, all as
provided in the Purchase Contract Agreement and more fully described on the
reverse hereof. The purchase price for the shares of Common Stock purchased
pursuant to each Purchase Contract evidenced hereby will be paid by application
of the Proceeds from the Treasury Securities pledged to secure the obligations
under such Purchase Contract in accordance with the terms of the Pledge
Agreement.

         The Company shall pay on each Payment Date in respect of each Purchase
Contract evidenced hereby an amount (the "Contract Adjustment Payments") equal
to ___% per annum of the Stated Amount, computed on the basis of the actual
number of days elapsed in a year of 360 day year of twelve 30 day months, as the
case may be, subject to deferral at the option of the Company as provided in the
Purchase Contract Agreement and more fully described on the reverse hereof. Such
Contract Adjustment Payments, if any, shall be payable to the Person in whose
name this Growth PRIDES Certificate (or a Predecessor Growth PRIDES Certificate)
is registered at the close of business on the Record Date for such Payment Date.

         Contract Adjustment Payments, if any, will be payable at the office of
the Agent in The City of New York or, at the option of the Company, by check
mailed to the address of the Person entitled thereto as such address appears on
the Growth PRIDES Register.

         Reference is hereby made to the further provisions set forth on the
reverse hereof, which further provisions shall for all purposes have the same
effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Agent by manual signature, this Growth PRIDES Certificate shall not be
entitled to any benefit under the Pledge Agreement or the Purchase Contract
Agreement or be valid or obligatory for any purpose.

         This is one of the Growth PRIDES referred to in the within-mentioned
Purchase Contract Agreement.

                                       By:   THE FIRST NATIONAL BANK OF
                                             CHICAGO, as Purchase Contract Agent


                                              By:______________________________
                                                       Authorized Signatory

                                   (Reverse of
                           Growth PRIDES Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of _____, 1998 (as may be supplemented from time to
time, the "Purchase Contract Agreement") between the Company and The First
National Bank of Chicago, 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 Growth PRIDES Certificates are, and are to be, executed and
delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company to sell, not later than
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
Reference 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 Amount is less than or equal to $_____, then _____ 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.

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

                                      -81-


<PAGE>   88



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
as reported by The New York Stock Exchange, Inc. (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 National 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 "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 Growth PRIDES Certificate shall pay the Purchase Price for the
shares of 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 of the Pledged Treasury Securities underlying
such Holder's Growth PRIDES 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 shares of 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 shares of 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 Growth PRIDES 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 Growth
PRIDES from the Pledge.

         The Growth PRIDES Certificates are issuable only in registered form and
only in denominations of a single Growth PRIDES and any integral multiple
thereof. The transfer of any Growth PRIDES Certificate will be registered and
Growth PRIDES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Growth PRIDES 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

                                      -82-


<PAGE>   89



payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Preferred
Securities or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, for Treasury Securities, thereby recreating
Income PRIDES, shall be responsible for any fees or expenses associated
therewith. Except as provided in the Purchase Contract Agreement, for so long as
the Purchase Contract underlying a Growth PRIDES remains in effect, such Growth
PRIDES shall not be separable into its constituent parts, and the rights and
obligations of the Holder of such Growth PRIDES in respect of the Treasury
Security and the Purchase Contract constituting such Growth PRIDES may be
transferred and exchanged only as a Growth PRIDES. A Holder of Growth PRIDES may
create or recreate Income PRIDES by delivering to the Collateral Agent Preferred
Securities or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, with a Stated Amount, in the case of such Preferred 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 of the Treasury Portfolio, equal to
the aggregate principal amount of the Pledged Treasury Securities in exchange
for the release of such Pledged Treasury Securities in accordance with the terms
of the Purchase Contract Agreement and the Pledge Agreement. From and after such
substitution, the Holder's Security shall be referred to as an "Income PRIDES."
Such substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, the equivalent
aggregate principal amount outstanding under this Growth PRIDES Certificate
shall not exceed $__________. All such adjustments to the equivalent aggregate
principal amount of this Growth PRIDES Certificate shall be duly recorded by
placing an appropriate notation on the Schedule attached hereto.

         A Holder of an Income PRIDES may create or recreate a Growth PRIDES by
delivering to the Collateral Agent Treasury Securities in an aggregate principal
amount equal to the aggregate Stated Amount of the Pledged Preferred 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 Preferred Securities or the appropriate
Applicable Ownership Interest of 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 Growth PRIDES may be effected only in
multiples of 40 Income PRIDES for 40 Growth PRIDES; provided, however, if a Tax
Event Redemption has occurred and the Treasury Portfolio has become a component
of the Income PRIDES, a Holder may make such Collateral Substitution in integral
multiples of 1,600,000 Income PRIDES for 1,600,000 Growth PRIDES.

         Subject to the next succeeding paragraph, the Company shall pay, on
each Payment Date, the Contract Adjustment Payments, if any, payable in respect
of each Purchase Contract to the Person in whose name the Growth PRIDES
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the office of the Agent in The City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Growth PRIDES Register.

                                      -83-

         The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) as provided in the
Purchase Contract Agreement. Any Contract Adjustment Payments, if any, so
deferred shall bear additional Contract Adjustment Payments thereon at the rate
of ____% per annum (computed on the basis of a 360 day year of twelve 30 day
months), compounding on each succeeding Payment Date, until paid in full (such
deferred installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments accrued thereon, are referred to herein
as the "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment
Payments shall be due on the next succeeding Payment Date except to the extent
that payment is deferred pursuant to the Purchase Contract Agreement. No
Contract Adjustment Payments, if any, may be deferred to a date that is after
the Purchase Contract Settlement Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until the Purchase
Contract Settlement Date, the Holder of this Growth PRIDES Certificate will
receive on the Purchase Contract Settlement Date, in lieu of a cash payment, a
number of Shares of Common Stock equal to (x) the aggregate amount of Deferred
Contract Adjustment Payments payable to the Holder of the Growth PRIDES
Certificate divided by (y) the Applicable Market Value.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then, until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
or make guarantee payments with respect to the foregoing (other than (i)
purchases or acquisitions of shares of capital stock of the Company in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security outstanding on the date of such event
requiring the Company to purchase capital stock of the Company, (ii) as a result
of a reclassification of the Company's capital stock or the exchange or
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (iii) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of the Company's capital stock or the security being
converted or exchanged, (iv) dividends or distributions in capital stock of the
Company (or rights to acquire capital stock) or repurchases or redemptions of
capital stock solely from the issuance or exchange of capital stock or (v)
redemptions or repurchases of any rights outstanding under a shareholder rights
plan or the declaration thereunder of a dividend of rights in the future).

         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, if any, or any Deferred Contract

                                      -84-

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 Growth PRIDES 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 Growth
PRIDES Certificate, the Holder of this Growth PRIDES Certificate shall deliver
this Growth PRIDES 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, an amount equal to the Contract Adjustment Payments, if any,
payable on such Payment Date with respect to such Purchase Contracts. 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 Growth PRIDES as to which Early Settlement is
effected equal to ______ shares of Common Stock per Purchase Contract (the
"Early Settlement Rate"); provided however, that upon the Early Settlement of
the Purchase Contracts, the Holder thereof will forfeit the right to receive any
Deferred Contract Adjustment Payments and future Contract Adjustment Payments on
such Purchase Contracts. The Early Settlement Rate 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 Growth PRIDES 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 Growth
PRIDES 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 Growth PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Growth PRIDES evidenced hereby on his behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,

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 Contract Agent, as their attorney-in-fact, and the Purchase
Contract Agent, as such attorney-in-fact, hereby pledge and grant to the
Collateral Agent, for the benefit of the Company, as collateral security for the
performance when due by such Holders of their respective obligations under the
related Purchase Contracts, a security interest in all of the right, title and
interest of the Purchase Contract Agent and such Holders (a) in the Preferred
Securities and Treasury Securities constituting a part of the Securities and any
Treasury Securities delivered in exchange for any Preferred Securities, and any
Preferred Securities delivered in exchange for any Treasury Securities, in
accordance with Section 4 hereof, in each case that have been Transferred to or
received by the Collateral Agent and not released by the Collateral Agent to
such Holders under the provisions of this Agreement; (b) in payments made by
Holders pursuant to Section 4.4; (c) in the Collateral Account and all
securities, financial assets, Cash and other property credited thereto and all
Security Entitlements related thereto; (d) in any Debentures delivered to the
Collateral Agent upon the occurrence of an Investment Company Event or a

Portfolio purchased on behalf of the Holders of Income PRIDES by the Collateral
Agent upon the occurrence of a Tax Event Redemption as provided in Section 6.2

be Transferred to the Collateral Agent for the benefit of the Company. Such

                                       -6-

<PAGE>   10



Transferred by physically delivering such Securities to the Securities
Intermediary indorsed in blank and causing the Securities Intermediary to credit
the Collateral Account with such Securities and sending the Collateral Agent a
confirmation of the deposit of such Securities. In the event a Holder of Income
PRIDES so elects, such Holder may Transfer Treasury Securities to the Collateral
Agent for the benefit of the Company in exchange for the release by the
Collateral Agent on behalf of the Company of Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, with an aggregate stated liquidation amount equal to the aggregate
principal amount of the Treasury Securities so Transferred, in the case of
Preferred Securities, or with an appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio equal to the aggregate principal amount of the Treasury Securities so
transferred, in the event that a Tax Event Redemption has occurred, to the
Purchase Contract Agent on behalf of such Holder. Treasury Securities and the
Treasury Portfolio, as applicable, shall be Transferred to the Collateral
Account maintained by the Collateral Agent at the Securities Intermediary by
book-entry transfer to the Collateral Account in accordance with the TRADES
Regulations and other applicable law and by the notation by the Securities
Intermediary on its books that a Security Entitlement with respect to such
Treasury Securities or Treasury Portfolio, has been credited to the Collateral
Account. For purposes of perfecting the Pledge under applicable law, including,
to the extent applicable, the TRADES Regulations or the Uniform Commercial Code
as adopted and in effect in any applicable jurisdiction, the Collateral Agent
shall be the agent of the Company as provided herein. The pledge provided in
this Section 2.1 is herein referred to as the "Pledge" and the Preferred
Securities (or the Debentures that are delivered pursuant to Section 6.2 hereof)
or Treasury Securities subject to the Pledge, excluding any Preferred Securities
(or the Debentures that are delivered pursuant to Section 6.2 hereof) or
Treasury Securities released from the Pledge as provided in Section 4 hereof,
are hereinafter referred to as "Pledged Preferred Securities" or the "Pledged
Treasury Securities," respectively. Subject to the Pledge and the provisions of
Section 2.2 hereof, the Holders from time to time shall have full beneficial
ownership of the Collateral. Whenever directed by the Collateral Agent acting on
behalf of the Company, the Securities Intermediary shall have the right to
reregister the Preferred Securities or any other Securities held in physical
form in its name.

         Except as may be required in order to release Preferred Securities in
connection with a Holder's election to convert its investment from an Income
PRIDES to a Growth PRIDES, or except as otherwise required to release Securities
as specified herein, neither the Collateral Agent nor the Securities
Intermediary shall relinquish physical possession of any certificate evidencing
a Preferred Security prior to the termination of this Agreement. If it becomes
necessary for the Securities Intermediary to relinquish physical possession of a
certificate in order to release a portion of the Preferred Securities evidenced
thereby from the Pledge, the Securities Intermediary shall use its best efforts
to obtain physical possession of a replacement certificate evidencing any
Preferred Securities remaining subject to the Pledge hereunder registered to it
or endorsed in blank within fifteen days of the date it relinquished possession.
The Securities Intermediary shall promptly notify the Company and the Collateral
Agent of the Securities Intermediary's failure to obtain possession of any such
replacement certificate as required hereby.

         SECTION 2.2. CONTROL AND PERFECTION. (a) In connection with the Pledge
granted in Section 2.1, and subject to the other provisions of this Agreement,
the Holders from time to time acting through the Purchase Contract Agent, as
their attorney-in-fact, hereby authorize and direct the Securities Intermediary
(without the necessity of obtaining the further consent of the Purchase Contract
Agent or any of the Holders), and the Securities Intermediary agrees, to comply
with and follow any instructions and entitlement orders (as defined in Section
8-102(a)(8) of the Code) that the Collateral Agent on behalf of the Company may
give in writing with respect to the Collateral Account, the Collateral credited
thereto and any security entitlements with respect to any thereof. Such
instructions and entitlement orders may, without limitation, direct the
Securities Intermediary to transfer, redeem, sell, liquidate, assign, deliver or
otherwise dispose of the Preferred Securities, the Treasury Securities, the
Treasury Portfolio, and any Security Entitlements with respect thereto and to
pay and deliver any income, proceeds or other funds derived therefrom to the
Company. The Holders from time to time acting through the Purchase Contract
Agent hereby further authorize and direct the Collateral Agent, as Agent of the
Company, to itself issue instructions and entitlement orders, and to otherwise
take action, with respect to the Collateral Account, the Collateral credited
thereto and any security entitlements with respect thereto, pursuant to the
terms and provisions hereof, all without the necessity of obtaining the further
consent of the Purchase Contract Agent or any of the Holders. The Collateral
Agent shall be the Agent of the Company and shall act as directed in writing by
the Company. Without limiting the generality of the foregoing, the Collateral
Agent shall issue entitlement orders to the Securities Intermediary when and as
directed by the Company.

         (b) The Securities Intermediary hereby confirms and agrees that: (i)
all securities or other property underlying any financial assets credited to the
Collateral Account shall be registered in the name of the Securities
Intermediary, indorsed to the Securities Intermediary or in blank or credited to
another Collateral Account maintained in the name of the Securities Intermediary
and in no case will any financial asset credited to the Collateral Account be
registered in the name of the Purchase Contract Agent, the Collateral Agent, the
Company or any Holder, payable to the order of, or specially indorsed to, the
Purchase Contract Agent, the Collateral Agent, the Company or any Holder except
to the extent the foregoing have been specially indorsed to the Securities
Intermediary or in blank; (ii) all property delivered to the Securities
Intermediary pursuant to this Pledge Agreement (including, without limitation,
any Preferred Securities, the Treasury Portfolio or Treasury Securities) will be
promptly credited to the Collateral Account; (iii) the Collateral Account is an
account to which financial assets are or may be credited, and the Securities
Intermediary shall, subject to the terms of this Agreement, treat the Purchase
Contract Agent as entitled to exercise the rights of any financial asset
credited to the Collateral Account; (iv) the Securities Intermediary has not
entered into, and until the termination of this Agreement will not enter into,
any agreement with any other person relating to the Collateral Account and/or
any financial assets credited thereto pursuant to which it has agreed to comply
with entitlement orders (as defined in Section 8-102(a)(8) of the Code) of such
other person; and (v) the Securities Intermediary has not entered into, and
until the termination of this Agreement will not enter into, any agreement with
the Company, the Collateral Agent or the Purchase


                                       -8-

<PAGE>   12



Contract Agent purporting to limit or condition the obligation of the Securities
Intermediary to comply with entitlement orders as set forth in this Section 2.2
hereof.

         (c) The Securities Intermediary hereby agrees that each item of
property (whether investment property, financial asset, security, instrument or
cash) credited to the Collateral Account shall be treated as a "financial asset"
within the meaning of Section 8-102(a)(9) of the Code.

         (d) In the event of any conflict between this Agreement (or any portion
thereof) and any other agreement now existing or hereafter entered into, the
terms of this Agreement shall prevail.

         (e) The Purchase Contract Agent hereby irrevocably constitutes and
appoints the Collateral Agent and the Company, with full power of substitution,
as the Purchase Contract Agent's attorney-in-fact to take on behalf of, and in
the name, place and stead of the Purchase Contract Agent and the Holders, any
action necessary or desirable to perfect and to keep perfected the security
interest in the Collateral referred to in Section 2.1. The grant of such
power-of-attorney shall not be deemed to require of the Collateral Agent any
specific duties or obligations not otherwise assumed by the Collateral Agent
hereunder.

         SECTION 3. DISTRIBUTIONS ON PLEDGED COLLATERAL. So long as the Purchase
Contract Agent is the registered owner of the Pledged Preferred Securities, it
shall receive all payments thereon. If the Pledged Preferred Securities are
reregistered, such that the Collateral Agent becomes the registered holder, all
payments of the Stated Amount or, if applicable, the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, or cash distributions on, the Pledged Preferred
Securities or on the appropriate Applicable Ownership Interest (as specified in
clause (B) of the definition of such term) of the Treasury Portfolio, as the
case may be, and all payments of the principal of, or cash distributions on, any
Pledged Treasury Securities received by the Collateral Agent that are properly

                  (i) In the case of (A) cash distributions with respect to the
         Pledged Preferred Securities or the appropriate Applicable Ownership
         Interest (as specified in clause (B) of the definition of such term) of

         appropriate Applicable Ownership Interest of the Treasury Portfolio, as
         the case may be, that have been released from the Pledge pursuant to
         Section 4.3 hereof, to the Purchase Contract Agent, for the benefit of
         the relevant Holders of Securities, to the account designated by the
         Purchase Contract Agent for such purpose, no later than 2:00 p.m., New
         York City time, on the Business Day such payment is received by the
         Collateral Agent (provided that in the event such payment is received
         by the Collateral Agent on a day that is not a Business Day or after
         12:30 p.m., New York City time, on a


                                       -9-

<PAGE>   13



         Business Day, then such payment shall be made no later than 10:30 a.m.,
         New York City time, on the next succeeding Business Day);

                  (ii) In the case of any principal payments with respect to any
         Treasury Securities that have been released from the Pledge pursuant to
         Section 4.3 hereof, to the Holders of the Growth PRIDES to the accounts
         designated by them in writing for such purpose no later than 2:00 p.m.,
         New York City time, on the Business Day such payment is received by the
         Collateral Agent (provided that in the event such payment is received
         by the Collateral Agent on a day that is not a Business Day or after
         12:30 p.m., New York City time, on a Business Day, then such payment
         shall be made no later than 10:30 a.m., New York City time, on the next
         succeeding Business Day); and

                  (iii) In the case of payments of the Stated Amount of any
         Pledged Preferred 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, or the principal of any
         Pledged Treasury Securities, to the Company on the Purchase Contract
         Settlement Date in accordance with the procedure set forth in Section
         4.6(a) or 4.6(b) hereof, in full satisfaction of the respective
         obligations of the Holders under the related Purchase Contracts.

All payments received by the Purchase Contract Agent as provided herein shall be
applied by the Purchase Contract Agent pursuant to the provisions of the
Purchase Contract Agreement. If, notwithstanding the foregoing, the Purchase
Contract Agent shall receive any payments of the Stated Amount or, if
applicable, the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) on account of any Preferred Security
or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
applicable, that, at the time of such payment, is a Pledged Preferred Security
or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, or a Holder of a Growth PRIDES shall receive any payments of
principal on account of any Treasury Securities that, at the time of such

Holder shall hold the same as trustee of an express trust for the benefit of the
Company (and promptly deliver the same over to the Company) for application to
the obligations of the Holders under the related Purchase Contracts, and the
Holders shall acquire no right, title or interest in any such payments of Stated
Amount or principal so received.

         SECTION 4. SUBSTITUTION, RELEASE, REPLEDGE AND SETTLEMENT OF PREFERRED

Treasury Securities for the Pledged Preferred Securities securing such Holder's
obligations under the Purchase Contract(s) comprising a part of its Income
PRIDES in integral multiples of 40 Income PRIDES by (a)


                                      -10-

<PAGE>   14



Transferring to the Collateral Agent Treasury Securities having a Value equal to
the aggregate Stated Amount of the Pledged Preferred Securities to be released
and (b)(i) delivering to the Purchase Contract Agent cash in an amount equal to
the excess of the Contract Adjustment Payments, if any, that would have accrued
since the last date that Contract Adjustment Payments were made through the date
of substitution on the Growth PRIDES being created by the Holder, which amount
the Purchase Contract Agent shall promptly remit to the Company, and (ii)
delivering the related Income PRIDES to the Purchase Contract Agent, accompanied
by a notice, substantially in the form of Exhibit B hereto, to the Purchase
Contract Agent stating that such Holder has Transferred Treasury Securities to
the Collateral Agent pursuant to clause (a) above (stating the Value of the
Treasury Securities Transferred by such Holder) and requesting that the Purchase
Contract Agent instruct the Collateral Agent to release from the Pledge the
Pledged Preferred Securities related to such Income PRIDES. The Purchase
Contract Agent shall instruct the Collateral Agent in the form provided in
Exhibit A; provided, however, that if a Tax Event Redemption has occurred and
the Treasury Portfolio has become a component of the Income PRIDES, Holders of
Income PRIDES may make such substitution only in integral multiples of 1,600,000
Income PRIDES at any time on or prior to the second Business Day immediately
preceding the Purchase Contract Settlement Date. Upon receipt of Treasury
Securities from a Holder of Income PRIDES and the related instruction from the
Purchase Contract Agent, the Collateral Agent shall release the Pledged
Preferred Securities or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, and shall promptly Transfer such Pledged
Preferred Securities or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, free and clear of any lien, pledge or
security interest created hereby, to the Purchase Contract Agent. All items
Transferred and/or substituted by any Holder pursuant to this Section 4.1,
Section 4.2 or any other Section of this Agreement shall be Transferred and/or
substituted free and clear of all liens, claims and encumbrances.

         SECTION 4.2. SUBSTITUTION OF TREASURY SECURITIES AND THE CREATION OF
INCOME PRIDES. At any time on or prior to the fifth Business Day immediately
preceding the Purchase Contract Settlement Date (unless a Tax Event Redemption
has occurred), a Holder of Growth PRIDES shall have the right to establish or
reestablish Income PRIDES consisting of the Purchase Contracts and Preferred
Securities in integral multiples of 40 Income PRIDES by (a) Transferring to the
Collateral Agent Preferred Securities having a Value equal to the Value of the
Pledged Treasury Securities to be released and (b) delivering the related Growth
PRIDES to the Purchase Contract Agent, accompanied by a notice, substantially in
the form of Exhibit B hereto, to the Purchase Contract Agent stating that such
Holder has transferred Preferred Securities to the Collateral Agent pursuant to
clause (a) above and requesting that the Purchase Contract Agent instruct the
Collateral Agent to release from the Pledge the Pledged Treasury Securities
related to such Growth PRIDES. The Purchase Contract Agent shall instruct the
Collateral Agent in the form provided in Exhibit A; provided, however, that if a
Tax Event Redemption has occurred and the Treasury Portfolio has become a
component of the Income PRIDES, Holders of Growth PRIDES may make such
substitution only in integral multiples of 1,600,000 Growth PRIDES, at any time
on or prior to the Business Day immediately preceding the Purchase


                                      -11-

<PAGE>   15



Contract Settlement Date. Upon receipt of the Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, from such Holder and the instruction from the Purchase Contract Agent,
the Collateral Agent shall release the Treasury Securities and shall promptly
Transfer such Treasury Securities, free and clear of any lien, pledge or
security interest created hereby, to the Purchase Contract Agent.

         SECTION 4.3. TERMINATION EVENT. Upon receipt by the Collateral Agent of
written notice from the Company or the Purchase Contract Agent that there has
occurred a Termination Event, the Collateral Agent shall release all Collateral
from the Pledge and shall promptly Transfer any Pledged Preferred Securities (or
the Applicable Ownership Interest of the Treasury Portfolio if a Tax Event
Redemption has occurred) and Pledged Treasury Securities to the Purchase
Contract Agent for the benefit of the Holders of the Income PRIDES and the
Growth PRIDES, respectively, free and clear of any lien, pledge or security
interest or other interest created hereby.

         If such Termination Event shall result from the Company's becoming a
debtor under the Bankruptcy Code, and if the Collateral Agent shall for any
reason fail promptly to effectuate the release and Transfer of all Pledged
Preferred Securities, the Treasury Portfolio or of the Pledged Treasury
Securities, as the case may be, as provided by this Section 4.3, the Purchase
Contract Agent shall (i) use its best efforts to obtain an opinion of a
nationally recognized law firm reasonably acceptable to the Collateral Agent to
the effect that, as a result of the Company's being the debtor in such a
bankruptcy case, the Collateral Agent will not be prohibited from releasing or
Transferring the Collateral as provided in this Section 4.3, and shall deliver
such opinion to the Collateral Agent within ten days after the occurrence of
such Termination Event, and if (y) the Purchase Contract Agent shall be unable
to obtain such opinion within ten days after the occurrence of such Termination
Event or (z) the Collateral Agent shall continue, after delivery of such
opinion, to refuse to effectuate the release and Transfer of all Pledged
Preferred Securities, the Treasury Portfolio or the Pledged Treasury Securities,
as the case may be, as provided in this Section 4.3, then the Purchase Contract
Agent shall within fifteen days after the occurrence of such Termination Event
commence an action or proceeding in the court with jurisdiction of the Company's
case under the Bankruptcy Code seeking an order requiring the Collateral Agent
to effectuate the release and transfer of all Pledged Preferred Securities, the
Treasury Portfolio or of the Pledged Treasury Securities, as the case may be, as
provided by this Section 4.3 or (ii) commence an action or proceeding like that
described in subsection (i)(z) hereof within ten days after the occurrence of
such Termination Event.

         SECTION 4.4. CASH SETTLEMENT. (a) Upon receipt by the Collateral Agent
of (i) a notice from the Purchase Contract Agent promptly after the receipt by
the Purchase Contract Agent of such notice that a Holder of an Income PRIDES or
Growth PRIDES has elected, in accordance with the procedures specified in
Section 5.4(a)(i) or (d)(i) of the Purchase Contract Agreement, respectively, to
settle its Purchase Contract with Cash and (ii) payment of the amount required
to settle such contract by such Holder on or prior to 11:00 a.m., New York City
time, on the Business Day immediately preceding the Purchase Contract


                                      -12-

<PAGE>   16



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 Company, then the Collateral Agent shall promptly invest any Cash
received from a Holder in connection with a Cash Settlement in Permitted
Investments. Upon receipt of the proceeds upon the maturity of the Permitted
Investments on the Purchase Contract Settlement Date, the Collateral Agent shall
pay the portion of such proceeds and deliver any certified or cashiers' checks
received and any funds so wired, in an aggregate amount equal to the Purchase
Price, to the Company on the Purchase Contract Settlement Date, and shall
distribute any funds in respect of the interest earned from the Permitted
Investments to the Purchase Contract Agent for payment to the relevant Holders.

         (b) If a Holder of an Income PRIDES fails to notify the Agent of its
intention to make a Cash Settlement in accordance with Section 5.4(a)(i) of the
Purchase Contract Agreement, such failure shall constitute an event of default
under the Purchase Contract Agreement and hereunder, and the Holder shall be
deemed to have consented to the disposition of the Pledged Preferred Securities
pursuant to the remarketing as described in Section 5.4(b) of the Purchase
Contract Agreement, which is incorporated herein by reference. If a Holder of an
Income PRIDES does notify the Agent as provided in Section 5.4(a)(i) of the
Purchase Contract Agreement of its intention to pay the Purchase Price in cash,
but fails to make such payment as required by Section 5.4(a)(ii) of the Purchase
Contract Agreement, the Preferred 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 Preferred
Securities at the direction of the Company to retain or dispose of the
Collateral in accordance with applicable law. In addition, in the event of a
Failed Remarketing as described in Section 5.4(b) of the Purchase Contract
Agreement, such Failed Remarketing shall constitute an event of default
hereunder by such Holder and the Collateral Agent, for the benefit of the
Company, will also exercise its rights as a secured party with respect to such
Preferred Securities at the direction of the Company to retain or dispose of the
Collateral in accordance with applicable law.

         (c) If a Holder of a Growth PRIDES fails to notify the Purchase
Contract Agent of such Holder's intention to make a Cash Settlement in
accordance with Section 5.4(d)(i) of the Purchase Contract Agreement, or if a
Holder of a Growth PRIDES does notify the Agent as provided in paragraph 5.4
(d)(i) of the Purchase Contract Agreement of its intention to pay the Purchase
Price in cash, but fails to make such payment as required by paragraph
5.4(d)(ii) of the Purchase Contract Agreement, such failure shall constitute an
event of default hereunder by such Holder and upon the maturity of any Pledged
Treasury Securities or the Treasury Portfolio, if any, held by the Collateral
Agent on the Business Day immediately preceding the Purchase Contract Settlement
Date, the principal amount of the Pledged Treasury Securities or the Treasury
Portfolio received by the Collateral Agent shall, upon written direction of the
Company, be invested promptly in Permitted Investments. On the Purchase Contract
Settlement Date, an amount equal to the Purchase Price will be remitted to the
Company as payment thereof. In the event the sum of the proceeds from the
related Pledged Treasury Securities or the Treasury Portfolio, as the case may
be, and the investment earnings earned from such investments is in excess of the
aggregate Purchase


                                      -13-

<PAGE>   17



Price of the Purchase Contracts being settled thereby, the Collateral Agent will
distribute such excess to the Purchase Contract Agent for the benefit of the
Holder of the related Growth PRIDES or Income PRIDES when received.

         SECTION 4.5. EARLY SETTLEMENT. Upon written notice to the Collateral
Agent by the Purchase Contract Agent that one or more Holders of Securities have
elected to effect Early Settlement of their respective obligations under the
Purchase Contracts forming a part of such Securities in accordance with the
terms of the Purchase Contracts and the Purchase Contract Agreement (setting
forth the number of such Purchase Contracts as to which such Holders have
elected to effect Early Settlement), and that the Purchase Contract Agent has
received from such Holders, and paid to the Company as confirmed in writing by
the Company, the related Early Settlement Amounts pursuant to the terms of the
Purchase Contracts and the Purchase Contract Agreement and that all conditions
to such Early Settlement have been satisfied, then the Collateral Agent shall
release from the Pledge, (a) Pledged Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio in the case of a Holder
of Income PRIDES or (b) Pledged Treasury Securities in the case of a Holder of
Growth PRIDES, as the case may be, with a principal amount equal to the product
of (i) the Stated Amount times (ii) the number of such Purchase Contracts as to
which such Holders have elected to effect Early Settlement and shall Transfer
all such Pledged Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio or Pledged Treasury Securities, as the case
may be, free and clear of the Pledge created hereby, to the Purchase Contract
Agent for the benefit of the Holders.

         SECTION 4.6. APPLICATION OF PROCEEDS SETTLEMENT. (a) In the event a
Holder of Income PRIDES (if a Tax Event Redemption has not occurred) has not
elected to make an effective Cash Settlement by notifying the Purchase Contract
Agent in the manner provided for in paragraph 5.4(a)(i) in the Purchase Contract
Agreement or has not made an Early Settlement of the Purchase Contract(s)
underlying its Income PRIDES, such Holder shall be deemed to have elected to pay
for the shares of Common Stock to be issued under such Purchase Contract(s) from
the Proceeds of the related Pledged Preferred Securities. The Collateral Agent
shall, by 10:00 a.m., New York City time, on the fourth Business Day immediately
preceding the Purchase Contract Settlement Date, without any instruction from
such Holder of Income PRIDES, present the related Pledged Preferred Securities
to the Remarketing Agent for remarketing. Upon receiving such Pledged Preferred
Securities, the Remarketing Agent, pursuant to the terms of the Remarketing
Agreement and the Remarketing Underwriting Agreement, will use its reasonable
efforts to remarket such Pledged Preferred Securities on such date at a price
not less than approximately 100.50% of the aggregate Value of such Pledged
Preferred Securities, plus accrued and unpaid distributions (including deferred
distributions), if any, thereon. After deducting as the Remarketing Fee an
amount not exceeding 25 basis points (.25%) of the aggregate Value of the
Pledged Preferred Securities from any amount of such Proceeds in excess of the
aggregate Value, plus such accrued and unpaid distributions (including deferred
distributions) of the remarketed Pledged Preferred Securities, the Remarketing
Agent will remit the entire amount of the Proceeds of such remarketing to the
Collateral Agent. On the Purchase Contract Settlement Date, the Collateral Agent
shall apply that portion of the Proceeds from


                                      -14-

<PAGE>   18



such remarketing equal to the aggregate Value, plus such accrued and unpaid
distributions (including deferred distributions) of such Pledged Preferred
Securities, to satisfy in full the obligations of such Holders of Income PRIDES
to pay the Purchase Price to purchase the Common Stock under the related
Purchase Contracts. The remaining portion of such Proceeds, if any, shall be
distributed by the Collateral Agent to the Purchase Contract Agent for payment
to the Holders. If the Remarketing Agent advises the Collateral Agent in writing
that it cannot remarket the related Pledged Preferred Securities of such Holders
of Income PRIDES at a price not less than 100% of the aggregate Value of such
Pledged Preferred Securities plus any accrued and unpaid distributions
(including deferred distributions), thus resulting in a Failed Remarketing and
an event of default under the Purchase Contract Agreement and hereunder, the
Collateral Agent, for the benefit of the Company will, at the written direction
of the Company, retain or dispose of the Pledged Preferred Securities in
accordance with applicable law and satisfy in full, from any such disposition or
retention, such Holder's obligation to pay the Purchase Price for the Common
Stock.

         (b) In the event a Holder of Growth PRIDES or Income PRIDES (if a Tax
Event Redemption has occurred) has not made an Early Settlement of the Purchase
Contract(s) underlying its Growth PRIDES or Income PRIDES, such Holder shall be
deemed to have elected to pay for the shares of Common Stock to be issued under
such Purchase Contract(s) from the Proceeds of the related Pledged Treasury
Securities or the Treasury Portfolio, as the case may be. On the Business Day
immediately prior to the Purchase Contract Settlement Date, the Collateral Agent
shall, at the written direction of the Purchase Contract Agent, invest the Cash
proceeds of the maturing Pledged Treasury Securities or the Treasury Portfolio,
as the case may be, in overnight Permitted Investments. Without receiving any
instruction from any such Holder of Growth PRIDES or Income PRIDES, the
Collateral Agent shall apply the Proceeds of the related Pledged Treasury
Securities or Treasury Portfolio to the settlement of such Purchase Contracts on
the Purchase Contract Settlement Date.

         In the event the sum of the Proceeds from the related Pledged Treasury
Securities or Treasury Portfolio and the investment earnings from the investment
in overnight Permitted Investments is in excess of the aggregate Purchase Price
of the Purchase Contracts being settled thereby, the Collateral Agent shall
distribute such excess, when received, to the Purchase Contract Agent for the
benefit of the Holders.

         (c) Pursuant to the Remarketing Agreement and subject to the terms of
the Remarketing Underwriting Agreement, on or prior to the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, but no earlier than
the Payment Date immediately preceding the Purchase Contract Settlement Date,
holders of Separate Preferred Securities may elect to have their Separate
Preferred Securities remarketed by delivering their Separate Preferred
Securities, together with a notice of such election, substantially in the form
of Exhibit C hereto, to the Custodial Agent. The Custodial Agent will hold such
Separate Preferred Securities in an account separate from the Collateral
Account. A holder of Separate Preferred Securities electing to have its Separate
Preferred Securities remarketed will also have the right to withdraw such
election by written notice to the Custodial Agent,


                                      -15-

<PAGE>   19



substantially in the form of Exhibit D hereto, on or prior to the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, upon which
notice the Custodial Agent will return such Separate Preferred Securities to
such holder. On the fourth Business Day immediately preceding the Purchase
Contract Settlement Date, the Custodial Agent will deliver to the Remarketing
Agent for remarketing all separate Preferred Securities delivered to the
Custodial Agent pursuant to this Section 4.6(c) and not withdrawn pursuant to
the terms hereof prior to such date. The portion of the proceeds from such
remarketing equal to the aggregate Value of such Separate Preferred Securities
will automatically be remitted by the Remarketing Agent to the Custodial Agent
for the benefit of the holders of such Separate Preferred Securities. In
addition, after deducting as the Remarketing Fee an amount not exceeding 25
basis points (.25%) of the Value of the remarketed Separate Preferred
Securities, from any amount of such proceeds in excess of the aggregate Value of
the remarketed Separate Preferred Securities plus any accrued and unpaid
distributions (including deferred distributions, if any), the Remarketing Agent
will remit to the Custodial Agent the remaining portion of the proceeds, if any,
for the benefit of such holders. If, despite using its reasonable efforts, the
Remarketing Agent advises the Custodial Agent in writing that it cannot remarket
the related Separate Preferred Securities of such holders at a price not less
than 100% of the aggregate Value of such Separate Preferred Securities plus
accrued and unpaid distributions (including deferred distributions) and thus
resulting in a Failed Remarketing, the Remarketing Agent will promptly return
such Preferred Securities to the Custodial Agent for redelivery to such holders.
In the event of a dissolution of the Trust and the distribution of the
Debentures as described in the Trust Agreement, all references to "Separate
Preferred Securities" in this Section 4.6(c) shall be deemed to be references to
Debentures which are not pledged hereunder or required to be part of the
Collateral.

         SECTION 5. VOTING RIGHTS -- PREFERRED SECURITIES. The Purchase Contract
Agent may exercise, or refrain from exercising, any and all voting and other
consensual rights pertaining to the Pledged Preferred Securities or any part
thereof for any purpose not inconsistent with the terms of this Agreement and in
accordance with the terms of the Purchase Contract Agreement; provided, that the
Purchase Contract Agent shall not exercise or, as the case may be, shall not
refrain from exercising such right if, in the judgment of the Company, such
action would impair or otherwise have a material adverse effect on the value of
all or any of the Pledged Preferred Securities; and provided, further, that the
Purchase Contract Agent shall give the Company and the Collateral Agent at least
five days' prior written notice of the manner in which it intends to exercise,
or its reasons for refraining from exercising, any such right. Upon receipt of
any notices and other communications in respect of any Pledged Preferred
Securities, including notice of any meeting at which holders of Preferred
Securities are entitled to vote or solicitation of consents, waivers or proxies
of holders of Preferred Securities, the Collateral Agent shall use reasonable
efforts to send promptly to the Purchase Contract Agent such notice or
communication, and as soon as reasonably practicable after receipt of a written
request therefor from the Purchase Contract Agent, execute and deliver to the
Purchase Contract Agent such proxies and other instruments in respect of such
Pledged Preferred Securities (in form and substance satisfactory to the
Collateral Agent) as are prepared by the Purchase Contract Agent with respect to
the Pledged Preferred Securities.

         SECTION 6. RIGHTS AND REMEDIES; DISTRIBUTION OF THE DEBENTURES; TAX
EVENT REDEMPTION

         SECTION 6.1. RIGHTS AND REMEDIES OF THE COLLATERAL AGENT. (a) In
addition to the rights and remedies specified in Section 4.4 hereof or otherwise
available at law or in equity, after an event of default hereunder, the
Collateral Agent shall have all of the rights and remedies with respect to the
Collateral of a secured party under the Uniform Commercial Code (or any
successor thereto) as in effect in the State of New York from time to time (the
"Code") (whether or not the Code is in effect in the jurisdiction where the
rights and remedies are asserted) and the TRADES Regulations and such additional
rights and remedies to which a secured party is entitled under the laws in
effect in any jurisdiction where any rights and remedies hereunder may be
asserted. Wherever reference is made in this Agreement to any section of the
Code, such reference shall be deemed to include a reference to any provision of
the Code which is a successor to, or amendment of, such section. Without
limiting the generality of the foregoing, such remedies may include, to the
extent permitted by applicable law, (i) retention of the Pledged Preferred
Securities or other Collateral in full satisfaction of the Holders obligations
under the Purchase Contracts or (ii) sale of the Pledged Preferred Securities or
other Collateral in one or more public or private sales.

         (b) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, in the event the Collateral Agent is unable
to make payments to the Company on account of the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio or on account of principal payments of any Pledged
Treasury Securities as provided in Section 3 hereof in satisfaction of the
obligations of the Holder of the Securities of which such Pledged Treasury
Securities, or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as
applicable, is a part under the related Purchase Contracts, the inability to
make such payments shall constitute an event of default hereunder and the
Collateral Agent shall have and may exercise, with reference to such Pledged
Treasury Securities, or such appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as applicable, and such obligations of such Holder, any and all of
the rights and remedies available to a secured party under the Code and the
TRADES Regulations after default by a debtor, and as otherwise granted herein or
under any other law.

         (c) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, the Collateral Agent is hereby irrevocably
authorized to receive and collect all payments of (i) the Stated Amount of or,
cash distributions on, the Pledged Preferred Securities, (ii) the principal
amount of the Pledged Treasury Securities, or (iii) the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, subject, in each case, to the provisions of Section
3, and as otherwise granted herein.

                                      -17-

<PAGE>   21



         (d) The Purchase Contract Agent, individually and as attorney-in-fact
for each Holder of Securities, in the event such Holder becomes the Holder of a
Growth PRIDES, agrees that, from time to time, upon the written request of the
Collateral Agent, the Purchase Contract Agent or such Holder shall execute and
deliver such further documents and do such other acts and things as the
Collateral Agent may reasonably request in order to maintain the Pledge, and the
perfection and priority thereof, and to confirm the rights of the Collateral
Agent hereunder. The Purchase Contract Agent shall have no liability to any
Holder for executing any documents or taking any such acts requested by the
Collateral Agent hereunder, except for liability for its own negligent act, its
own negligent failure to act or its own willful misconduct.

         SECTION 6.2. DISTRIBUTION OF THE DEBENTURES; INVESTMENT COMPANY EVENT;
TAX EVENT REDEMPTION. Upon the occurrence of an Investment Company Event or a
liquidation of the Trust, a principal amount of the Debentures constituting the
assets of the Trust and underlying the Preferred Securities equal to the
aggregate stated liquidation amount of the Pledged Preferred Securities shall be
delivered to the Collateral Agent in exchange for the Pledged Preferred
Securities. In the event the Collateral Agent receives such Debentures in
respect of Pledged Preferred Securities upon the occurrence of an Investment
Company Event or liquidation of the Trust, the Collateral Agent shall Transfer
the Debentures to the Collateral Account in the manner specified herein
(including, without limitation, physical delivery thereof as set forth in
Section 2.1) for Pledged Preferred Securities to secure the obligations of the
Holders of Income PRIDES to purchase the Company's Common Stock under the
related Purchase Contracts. Thereafter, the Collateral Agent shall have such
security interests, rights and obligations with respect to the Debentures as it
had in respect of the Pledged Preferred Securities as provided in Sections 2, 3,
4, 5 and 6 hereof, and any reference herein to the Pledged Preferred Securities
shall be deemed to be referring to such Debentures.

         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 Debentures
shall be delivered to the Collateral Agent by the Property Trustee or upon a
dissolution of the Trust and the distribution of the related Debentures by the
Debenture Trustee on or prior to 12:30 p.m., New York City time, by check or
wire transfer in immediately available funds at such place and at such account
as may be designated by the Collateral Agent in exchange for the Pledged
Preferred Securities or Debentures, as the case may be. In the event the
Collateral Agent receives such Redemption Price, the Collateral Agent will, at
the written direction of the Company, apply an amount equal to the Redemption
Amount of such Redemption Price to purchase from the Quotation Agent the
Treasury Portfolio and promptly remit the remaining portion of such Redemption
Price to the Purchase Contract Agent for payment to the Holders of Income
PRIDES. The Collateral Agent shall Transfer the Treasury Portfolio to the
Collateral Account in the manner specified herein for Pledged Preferred
Securities to secure the obligation of all Holders of Income PRIDES to purchase
Common Stock of the Company under the Purchase Contracts constituting a part of
such Income PRIDES, in substitution for the Pledged Preferred Securities.
Thereafter the Collateral Agent shall have such security interests, rights and
obligations with respect to the Treasury Portfolio as it had in respect of


                                      -18-

<PAGE>   22

the Pledged Preferred Securities or Debentures, as the case may be, as provided
in Sections 2, 3, 4, 5 and 6, and any reference herein to the Pledged Preferred
Securities or the Debentures shall be deemed to be reference to such Treasury
Portfolio.

         SECTION 6.3. SUBSTITUTIONS. Whenever a Holder has the right to
substitute Treasury Securities, Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be, for
Collateral held by the Collateral Agent, such substitution shall not constitute
a novation of the security interest created hereby.

         SECTION 7. REPRESENTATIONS AND WARRANTIES; COVENANTS.

         SECTION 7.1. REPRESENTATIONS AND WARRANTIES. The Holders from time to
time, acting through the Purchase Contract Agent as their attorney-in-fact (it
being understood that the Purchase Contract Agent shall not be liable for any
representation or warranty made by or on behalf of a Holder), hereby represent
and warrant to the Collateral Agent, which representations and warranties shall
be deemed repeated on each day a Holder Transfers Collateral that:

                 (a)       such Holder has the power to grant a security
                           interest in and lien on the Collateral;

                 (b)       such Holder is the sole beneficial owner of the
                           Collateral and, in the case of Collateral delivered
                           in physical form, is the sole holder of such
                           Collateral and is the sole beneficial owner of, or
                           has the right to Transfer, the Collateral it
                           Transfers to the Collateral Agent, free and clear of
                           any security interest, lien, encumbrance, call,
                           liability to pay money or other restriction other
                           than the security interest and lien granted under
                           Section 2 hereof;

                 (c)       upon the Transfer of the Collateral to the Collateral
                           Account, the Collateral Agent, for the benefit of the
                           Company, will have a valid and perfected first
                           priority security interest therein (assuming that any
                           central clearing operation or any Intermediary or
                           other entity not within the control of the Holder
                           involved in the Transfer of the Collateral, including
                           the Collateral Agent, gives the notices and takes the
                           action required of it hereunder and under applicable
                           law for perfection of that interest and assuming the
                           establishment and exercise of control pursuant to
                           Section 2.2 hereof); and

                 (d)       the execution and performance by the Holder of its
                           obligations under this Agreement will not result in
                           the creation of any security interest, lien or other
                           encumbrance on the Collateral other than the security
                           interest and lien granted under Section 2 hereof or
                           violate any provision of any existing law or
                           regulation applicable to it or of any mortgage,

<PAGE>   23

                           charge, pledge, indenture, contract or undertaking to
                           which it is a party or which is binding on it or any
                           of its assets.

         SECTION 7.2. COVENANTS. The Holders from time to time, acting through
the Purchase Contract Agent as their attorney-in-fact (it being understood that
the Purchase Contract Agent shall not be liable for any covenant made by or on
behalf of a Holder), hereby covenant to the Collateral Agent that for so long as
the Collateral remains subject to the Pledge:

                 (a)       neither the Purchase Contract Agent nor such Holders
                           will create or purport to create or allow to subsist
                           any mortgage, charge, lien, pledge or any other
                           security interest whatsoever over the Collateral or
                           any part of it other than pursuant to this Agreement;
                           and

                 (b)       neither the Purchase Contract Agent nor such Holders
                           will sell or otherwise dispose (or attempt to
                           dispose) of the Collateral or any part of it except
                           for the beneficial interest therein, subject to the
                           pledge hereunder, transferred in connection with the
                           Transfer of the Securities.

         SECTION 8. THE COLLATERAL AGENT. It is hereby agreed as follows:

         SECTION 8.1. APPOINTMENT, POWERS AND IMMUNITIES. The Collateral Agent
shall act as Agent for the Company hereunder with such powers as are
specifically vested in the Collateral Agent by the terms of this Agreement,
together with such other powers as are reasonably incidental thereto. Each of
the Collateral Agent, the Custodial Agent and the Securities Intermediary: (a)
shall have no duties or responsibilities except those expressly set forth in
this Agreement and no implied covenants or obligations shall be inferred from
this Agreement against any of them, nor shall any of them be bound by the
provisions of any agreement by any party hereto beyond the specific terms
hereof; (b) shall not be responsible for any recitals contained in this
Agreement, or in any certificate or other document referred to or provided for
in, or received by it under, this Agreement, the Securities or the Purchase
Contract Agreement, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement (other than as against the
Collateral Agent), the Securities or the Purchase Contract Agreement or any
other document referred to or provided for herein or therein or for any failure
by the Company or any other Person (except the Collateral Agent, the Custodial
Agent or the Securities Intermediary, as the case may be) to perform any of its
obligations hereunder or thereunder or for the perfection, priority or, except
as expressly required hereby, maintenance of any security interest created
hereunder; (c) shall not be required to initiate or conduct any litigation or
collection proceedings hereunder (except in the case of the Collateral Agent,
pursuant to directions furnished under Section 8.2 hereof, subject to Section
8.6 hereof); (d) shall not be responsible for any action taken or omitted to be
taken by it hereunder or under any other document or instrument referred to or
provided for herein or in connection herewith or therewith, except for its own
negligence or willful misconduct; and (e) shall not be required to advise any
party as to selling or retaining, or taking or refraining from taking any action
with respect to, the Securities or other property deposited hereunder. Subject
to the foregoing, during the term of this


                                      -20-

<PAGE>   24



Agreement, the Collateral Agent shall take all reasonable action in connection
with the safekeeping and preservation of the Collateral hereunder.

         No provision of this Agreement shall require the Collateral Agent, the
Custodial Agent or the Securities Intermediary to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its
duties hereunder. In no event shall the Collateral Agent, the Custodial Agent or
the Securities Intermediary be liable for any amount in excess of the Value of
the Collateral. Notwithstanding the foregoing, the Collateral Agent, the
Custodial Agent, the Purchase Contract Agent and Securities Intermediary, each
in its individual capacity, hereby waive any right of setoff, bankers lien,
liens or perfection rights as securities intermediary or any counterclaim with
respect to any of the Collateral.

         SECTION 8.2. INSTRUCTIONS OF THE COMPANY. The Company shall have the
right, by one or more instruments in writing executed and delivered to the
Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be, to direct the time, method and place of conducting any proceeding
for the realization of any right or remedy available to the Collateral Agent, or
of exercising any power conferred on the Collateral Agent, the Custodial Agent
or the Securities Intermediary, as the case may be, or to direct the taking or
refraining from taking of any action authorized by this Agreement; provided,
however, that (i) such direction shall not conflict with the provisions of any
law or of this Agreement and (ii) the Collateral Agent, the Custodial Agent and
the Securities Intermediary shall be adequately indemnified as provided herein.
Nothing in this Section 8.2 shall impair the right of the Collateral Agent in
its discretion to take any action or omit to take any action which it deems
proper and which is not inconsistent with such direction.

         SECTION 8.3. RELIANCE BY COLLATERAL AGENT. Each of the Securities
Intermediary, the Custodial Agent and the Collateral Agent shall be entitled
conclusively to rely upon any certification, order, judgment, opinion, notice or
other communication (including, without limitation, any thereof by telephone,
telecopy, telex or facsimile) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons
(without being required to determine the correctness of any fact stated
therein), and upon advice and statements of legal counsel and other experts
selected by the Collateral Agent, the Custodial Agent or the Securities
Intermediary, as the case may be. As to any matters not expressly provided for
by this Agreement, the Collateral Agent, the Custodial Agent and the Securities
Intermediary shall in all cases be fully protected in acting, or in refraining
from acting, hereunder in accordance with instructions given by the Company in
accordance with this Agreement.

         SECTION 8.4. RIGHTS IN OTHER CAPACITIES. The Collateral Agent, the
Custodial Agent and the Securities Intermediary and their affiliates may
(without having to account therefor to the Company) accept deposits from, lend
money to, make their investments in and generally engage in any kind of banking,
trust or other business with the Purchase Contract Agent, any Holder of
Securities and any holder of separate Preferred Securities (and any of their
respective subsidiaries or affiliates) as if it were not acting as the
Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be, and the Collateral Agent,


                                      -21-

the Custodial Agent and the Securities Intermediary and their affiliates may
accept fees and other consideration from the Purchase Contract Agent, any Holder
of Securities or any holder of separate Preferred Securities without having to
account for the same to the Company; provided that each of the Securities
Intermediary, the Custodial Agent and the Collateral Agent covenants and agrees
with the Company that it shall not accept, receive or permit there to be created
in favor of itself and shall take no affirmative action to permit there to be
created in favor of any other Person, any security interest, lien or other
encumbrance of any kind in or upon the Collateral and the Collateral shall not
be commingled with any other assets of any such Person.

         SECTION 8.5. NON-RELIANCE ON COLLATERAL AGENT. None of the Securities
Intermediary, the Custodial Agent or the Collateral Agent shall be required to
keep itself informed as to the performance or observance by the Purchase
Contract Agent or any Holder of Securities of this Agreement, the Purchase
Contract Agreement, the Securities or any other document referred to or provided
for herein or therein or to inspect the properties or books of the Purchase
Contract Agent or any Holder of Securities. The Collateral Agent, the Custodial
Agent and the Securities Intermediary shall not have any duty or responsibility
to provide the Company or the Remarketing Agent with any credit or other
information concerning the affairs, financial condition or business of the
Purchase Contract Agent, any Holder of Securities or any holder of separate
Preferred Securities (or any of their respective subsidiaries or affiliates)
that may come into the possession of the Collateral Agent, the Custodial Agent
or the Securities Intermediary or any of their respective affiliates.

         SECTION 8.6. COMPENSATION AND INDEMNITY. The Company agrees: (i) to pay
each of the Collateral Agent and the Custodial Agent from time to time such
compensation as shall be agreed in writing between the Company and the
Collateral Agent or the Custodial Agent, as the case may be, for all services
rendered by each of them hereunder and (ii) to indemnify the Collateral Agent,
the Custodial Agent and the Securities Intermediary for, and to hold each of
them harmless from and against, any loss, liability or reasonable out-of-pocket
expense incurred without negligence, willful misconduct or bad faith on its
part, arising out of or in connection with the acceptance or administration of
its powers and duties under this Agreement, including the reasonable
out-of-pocket costs and expenses (including reasonable fees and expenses of
counsel) of defending itself against any claim or liability in connection with
the exercise or performance of such powers and duties. The Collateral Agent, the
Custodial Agent and the Securities Intermediary shall each promptly notify the
Company of any third party claim which may give rise to the indemnity hereunder
and give the Company the opportunity to participate in the defense of such claim
with counsel reasonably satisfactory to the indemnified party, and no such claim
shall be settled without the written consent of the Company, which consent shall
not be unreasonably withheld.

         SECTION 8.7. FAILURE TO ACT. In the event of any ambiguity in the
provisions of this Agreement or any dispute between or conflicting claims by or
among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, the Collateral Agent and the Custodial Agent shall
be entitled, after prompt notice to the Company and the Purchase Contract Agent,
at its sole option, to refuse to comply with any and all claims,

                                      -22-

<PAGE>   26



demands or instructions with respect to such property or funds so long as such
dispute or conflict shall continue, and neither the Collateral Agent nor the
Custodial Agent shall be or become liable in any way to any of the parties
hereto for its failure or refusal to comply with such conflicting claims,
demands or instructions. The Collateral Agent and the Custodial Agent shall be
entitled to refuse to act until either (i) such conflicting or adverse claims or
demands shall have been finally determined by a court of competent jurisdiction
or settled by agreement between the conflicting parties as evidenced in a
writing, satisfactory to the Collateral Agent or the Custodial Agent, as the
case may be, or (ii) the Collateral Agent or the Custodial Agent, as the case
may be, shall have received security or an indemnity reasonably satisfactory to
the Collateral Agent or the Custodial Agent, as the case may be, sufficient to
save the Collateral Agent or the Custodial Agent, as the case may be, harmless
from and against any and all loss, liability or reasonable out-of-pocket expense
which the Collateral Agent or the Custodial Agent, as the case may be, may incur
by reason of its acting without bad faith, willful misconduct or gross
negligence. The Collateral Agent or the Custodial Agent may in addition elect to
commence an interpleader action or seek other judicial relief or orders as the
Collateral Agent or the Custodial Agent, as the case may be, may deem necessary.
Notwithstanding anything contained herein to the contrary, neither the
Collateral Agent nor the Custodial Agent shall be required to take any action
that is in its opinion contrary to law or to the terms of this Agreement, or
which would in its opinion subject it or any of its officers, employees or
directors to liability.

         SECTION 8.8. RESIGNATION OF COLLATERAL AGENT. Subject to the
appointment and acceptance of a successor Collateral Agent or Custodial Agent as
provided below, (a) the Collateral Agent and the Custodial Agent may resign at
any time by giving notice thereof to the Company and the Purchase Contract Agent
as attorney-in-fact for the Holders of Securities, (b) the Collateral Agent and
the Custodial Agent may be removed at any time by the Company and (c) if the
Collateral Agent or the Custodial Agent fails to perform any of its material
obligations hereunder in any material respect for a period of not less than 20
days after receiving written notice of such failure by the Purchase Contract
Agent and such failure shall be continuing, the Collateral Agent or the
Custodial Agent may be removed by the Purchase Contract Agent. The Purchase
Contract Agent shall promptly notify the Company of any removal of the
Collateral Agent pursuant to clause (c) of the immediately preceding sentence.
Upon any such resignation or removal, the Company shall have the right to
appoint a successor Collateral Agent or Custodial Agent, as the case may be. If
no successor Collateral Agent or Custodial Agent, as the case may be, shall have
been so appointed and shall have accepted such appointment within 30 days after
the retiring Collateral Agent's or Custodial Agent's giving of notice of
resignation or such removal, then the retiring Collateral Agent or Custodial
Agent, as the case may be, may petition any court of competent jurisdiction for
the appointment of a successor Collateral Agent or Custodial Agent, as the case
may be. Each of the Collateral Agent and the Custodial Agent shall be a bank
which has an office in New York, New York with a combined capital and surplus of
at least $75,000,000. Upon the acceptance of any appointment as Collateral Agent
or Custodial Agent, as the case may be, hereunder by a successor Collateral
Agent or Custodial Agent, as the case may be, such successor shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Collateral Agent or Custodial Agent, as


                                      -23-

<PAGE>   27



the case may be, and the retiring Collateral Agent or Custodial Agent, as the
case may be, shall take all appropriate action to transfer any money and
property held by it hereunder (including the Collateral) to such successor. The
retiring Collateral Agent or Custodial Agent shall, upon such succession, be
discharged from its duties and obligations as Collateral Agent or Custodial
Agent hereunder. After any retiring Collateral Agent's or Custodial Agent's
resignation hereunder as Collateral Agent or Custodial Agent, the provisions of
this Section 8 shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the Collateral
Agent or Custodial Agent. Any resignation or removal of the Collateral Agent
hereunder shall be deemed for all purposes of this Agreement as the simultaneous
resignation or removal of the Custodial Agent and the Securities Intermediary.

         SECTION 8.9. RIGHT TO APPOINT AGENT OR ADVISOR. The Collateral Agent
shall have the right to appoint agents or advisors in connection with any of its
duties hereunder, and the Collateral Agent shall not be liable for any action
taken or omitted by, or in reliance upon the advice of, such agents or advisors
selected in good faith. The appointment of agents pursuant to this Section 8.9
shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

         SECTION 8.10. SURVIVAL. The provisions of this Section 8 shall survive
termination of this Agreement and the resignation or removal of the Collateral
Agent or the Custodial Agent.

         SECTION 8.11. EXCULPATION. Anything in this Agreement to the contrary
notwithstanding, in no event shall any of the Collateral Agent, the Custodial
Agent or the Securities Intermediary or their officers, employees or agents be
liable under this Agreement to any third party for indirect, special, punitive,
or consequential loss or damage of any kind whatsoever, including lost profits,
whether or not the likelihood of such loss or damage was known to the Collateral
Agent, the Custodial Agent or the Securities Intermediary, or any of them,
incurred without any act or deed that is found to be attributable to gross
negligence or willful misconduct on the part of the Collateral Agent, the
Custodial Agent or the Securities Intermediary.

         SECTION 9. AMENDMENT.

         SECTION 9.1. AMENDMENT WITHOUT CONSENT OF HOLDERS. Without the consent
of any Holders or the holders of any Separate Preferred Securities, the Company,
the Collateral Agent, the Custodial Agent, the Securities Intermediary and the
Purchase Contract Agent, at any time and from time to time, may amend this
Agreement, in form satisfactory to the Company, the Collateral Agent, the

                 (2) to add to the covenants of the Company for the benefit of
the Holders, or to surrender any right or power herein conferred upon the
Company so long as such covenants or such surrender do not adversely affect the
validity, perfection or priority of the security interests granted or created
hereunder; or

                 (3) to evidence and provide for the acceptance of appointment
hereunder by a successor Collateral Agent, Securities Intermediary or Purchase
Contract Agent; or

                 (4) to cure any ambiguity, to correct or supplement any

duly authorized, the Purchase Contract Agent, the Collateral Agent, the
Custodial Agent and the Securities Intermediary may amend this Agreement for the
purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the consent of the Holder of each
Outstanding Security adversely affected thereby,

                 (1) change the amount or type of Collateral underlying a
         Security (except for the rights of holders of Income PRIDES to
         substitute the Treasury Securities for the Pledged Preferred Securities
         or the appropriate Applicable Ownership Interest of the Treasury
         Portfolio, as the case may be, or the rights of Holders of Growth
         PRIDES to substitute Preferred Securities or the appropriate Applicable
         Ownership Interest of the Treasury Portfolio, as applicable, for the
         Pledged Treasury Securities), impair the right of the Holder of any
         Security to receive distributions on the underlying Collateral or
         otherwise adversely affect the Holder's rights in or to such
         Collateral; or

                 (2) otherwise effect any action that would require the consent
         of the Holder of each Outstanding Security affected thereby pursuant to
         the Purchase Contract Agreement if such action were effected by an
         agreement supplemental thereto; or

                 (3) reduce the percentage of Purchase Contracts the consent of
         whose Holders is required for any such amendment.

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

permitted by this Section, the Collateral Agent, the Custodial Agent, the
Securities Intermediary and the


                                      -25-

Purchase Contract Agent shall be entitled to receive and (subject to Section 6.1

Date, there shall have occurred a Termination Event or 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 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
Amount is less than or equal to $____, ____ 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 Income PRIDES to purchase at the Purchase Price, and the Company to
sell, a number of 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, Inc.
(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 Nasaq National Market, or, if
the Common Stock is not

                                       -5-


<PAGE>   6



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 "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 Income PRIDES Certificate shall pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Purchase Contract evidenced
hereby by effecting a Cash Settlement, an Early Settlement or from the proceeds
of a remarketing of the related Pledged Preferred Securities of such holders. A
Holder of Income PRIDES 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 shares of Common Stock to be issued under
the related Purchase Contract from the Proceeds of the sale of the related
Pledged Preferred 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 Preferred Securities related to this Income
PRIDES certificate, any accrued and unpaid distributions (including deferred
distributions) on such Pledged Preferred Securities will become payable by the
Company to the holder of this Income PRIDES Certificate in the manner provided
for in the Purchase Contract Agreement.

         The Company shall not be obligated to issue any shares of 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 shares of 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 Income PRIDES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Security (as defined in the Pledge Agreement) or the appropriate Applicable
Ownership Interest of the Treasury Portfolio forming a part of each Income
PRIDES, or the Liquidation Distribution received in respect of such Pledged
Preferred Security, from the Pledge. An Income PRIDES shall thereafter represent
the right to receive the Preferred Security or the appropriate Applicable
Ownership Interest of the Treasury Portfolio forming a part of such Income
PRIDES, or the

                                       -6-


<PAGE>   7



Liquidation Distribution received in respect of such Preferred Security, 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
Preferred Securities. Upon receipt of notice of any meeting at which holders of
Preferred Securities are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Securities, the Agent shall, as soon
as practicable thereafter, mail to the Income PRIDES holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Income PRIDES 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 Preferred Securities entitled to vote) shall
be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Preferred Securities constituting a part of such holder's
Income PRIDES and (c) stating the manner in which such instructions may be
given. Upon the written request of the Income PRIDES 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 Preferred Securities as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of an Income PRIDES, the Agent shall abstain from voting the Preferred
Security evidenced by such Income PRIDES.

         Upon the occurrence of an Investment Company Event or liquidation of
the Trust, a principal amount of the Debentures constituting the assets of the
Trust and underlying the Preferred Securities equal to the aggregate Stated
Amount of the Pledged Preferred Securities shall be delivered to the Collateral
Agent in exchange for Pledged Preferred Securities. Thereafter, the Debentures
shall be held by the Collateral Agent to secure the obligations of each Holder
of Income PRIDES to purchase shares of Common Stock under the Purchase Contracts
constituting a part of such Income PRIDES. Following the liquidation of the
Trust, the Holders and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Debentures as the Holders and the
Collateral Agent had in respect of the Pledged Preferred Securities, and any
reference in the Purchase Contract Agreement or Pledge Agreement to the
Preferred Securities shall be deemed to be a reference to the Debentures.

         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 Debentures
shall be delivered to the Collateral Agent in exchange for the Pledged Preferred
Securities. Thereafter, pursuant to the terms of the Pledge Agreement, the
Collateral Agent for the benefit of the Company will apply an amount equal to
the Redemption Amount of such Redemption Price to purchase, the Treasury
Portfolio and promptly remit the remaining portion of such Redemption Price to
the Agent for payment to the Holders of such Income PRIDES.

         Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Income PRIDES and the
Collateral Agent shall have such

                                       -7-


<PAGE>   8



security interests rights and obligations with respect to the Treasury Portfolio
as the Holder of Income PRIDES and the Collateral Agent had in respect of the
Preferred Security or Debentures, 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 Preferred Security or the Debenture shall be
deemed to be reference to such Treasury Portfolio.

         The Income PRIDES Certificates are issuable only in registered form and
only in denominations of a single Income PRIDES and any integral multiple
thereof. The transfer of any Income PRIDES Certificate will be registered and
Income PRIDES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Income PRIDES 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 Treasury
Securities for Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, thereby creating Growth PRIDES, 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 an Income PRIDES remains in effect, such Income PRIDES shall
not be separable into its constituent parts, and the rights and obligations of
the Holder of such Income PRIDES in respect of Preferred Securities or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, and Purchase Contract constituting such Income PRIDES may be transferred
and exchanged only as an Income PRIDES. The holder of an Income PRIDES may
substitute for the Pledged Preferred Securities or the appropriate Applicable
Ownership Interest of the Treasury Portfolio securing its obligation under the
related Purchase Contract, Treasury Securities in an aggregate principal amount
equal to the aggregate Stated Amount of the Pledged Preferred 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 "Growth PRIDES." A Holder may make such Collateral Substitution only in
integral multiples of 40 Income PRIDES for 40 Growth PRIDES; provided, however,
that if a Tax Event Redemption has occurred and the Treasury Portfolio has
become a component of the Income PRIDES, a Holder may make such Collateral
Substitutions only in integral multiples of 1,600,000 Income PRIDES for
1,600,000 Growth PRIDES. Such Collateral Substitution may cause the equivalent
aggregate principal amount of this Certificate to be increased or decreased;
provided, however, the equivalent aggregate principal amount outstanding under
this Income PRIDES Certificate shall not exceed $_____________. All such
adjustments to the equivalent aggregate principal amount of this Income PRIDES
Certificate shall be duly recorded by placing an appropriate notation on the
Schedule attached hereto.

         A Holder of Growth PRIDES may create or recreate Income PRIDES by
delivering to the Collateral Agent Preferred Securities or the appropriate
Applicable Ownership Interest of the

                                       -8-


<PAGE>   9



Treasury Portfolio, with a Stated Amount, in the case of such Preferred
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 of the Treasury
Portfolio, equal to the aggregate principal amount of the Pledged Treasury
Securities in exchange for the release of such Pledged Treasury Securities in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.
         Subject to the next succeeding paragraph, the Company shall pay, on
each Payment Date, the Contract Adjustment Payments, if any, payable in respect
of each Purchase Contract to the Person in whose name the Income PRIDES
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the office of the Agent in The City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Income PRIDES Register.

         The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) as provided in the
Purchase Contract Agreement. Any Contract Adjustment Payments, if any, so
deferred shall bear additional Contract Adjustment Payments thereon at the rate
of ____% per annum (computed on the basis of a 360 day year of twelve 30 day
months), compounding on each succeeding Payment Date, until paid in full (such
deferred installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments accrued thereon, are referred to herein
as the "Deferred Contract Adjustment Payments"). Deferred Contract Adjustment
Payments, if any, shall be due on the next succeeding Payment Date except to the
extent that payment is deferred pursuant to the Purchase Contract Agreement. No
Contract Adjustment Payments, if any, may be deferred to a date that is after
the Purchase Contract Settlement Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until the Purchase Contract
Settlement Date, the Holder of this Income PRIDES Certificate will receive on
the Purchase Contract Settlement Date, in lieu of a cash payment, a number of
shares of Common Stock equal to (x) the aggregate amount of Deferred Contract
Adjustment Payments payable to the Holder of this Income PRIDES Certificate
divided by (y) the Applicable Market Value.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
or make guarantee payments with respect to the foregoing (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring

                                       -9-


<PAGE>   10



the Company to purchase capital stock of the Company, (ii) as a result of a
reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the Company's capital stock for another class or series
of the Company's capital stock, (iii) the purchase of fractional interests in
shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(iv) dividends or distributions in capital stock of the Company (or rights to
acquire capital stock) or repurchases or redemptions of capital stock solely
from the issuance or exchange of capital stock or (v) redemptions or repurchases
of any rights outstanding under a shareholder rights plan or a declaration
thereunder of a dividend of rights in the future).

         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 any Contract
Adjustment Payments, if any, or any Deferred 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
Income PRIDES Register. Upon and after the occurrence of a Termination Event,
the Collateral Agent shall release the Preferred Securities or the appropriate
Applicable Ownership Interest of 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
Income PRIDES, Holders may early settle Income PRIDES only in integral multiples
of 1,600,000 Income PRIDES. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Income
PRIDES Certificate, the Holder of this Income PRIDES Certificate shall deliver
this Income PRIDES 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, an amount equal to the Contract Adjustment Payments, if any,
payable on such Payment Date with respect to such Purchase Contracts. Upon Early
Settlement of Purchase Contracts by a Holder of the related Securities, the
Pledged Preferred Securities or the appropriate Applicable Ownership Interest of
the Treasury Portfolio underlying such Securities shall be released from the
Pledge as provided in the Pledge Agreement and the Holder shall be

                                     -10-


<PAGE>   11



entitled to receive a number of shares of Common Stock on account of each
Purchase Contract forming part of a Income PRIDES as to which Early Settlement
is effected equal to the Early Settlement Rate; provided however, that upon the
Early Settlement of the Purchase Contracts, the Holder thereof will forfeit the
right to receive any Deferred Contract Adjustment Payments on such Purchase
Contracts. 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 Income PRIDES 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 Income
PRIDES 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 Income PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Income PRIDES 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 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 its behalf as its attorney-in-fact, and consents to the
Pledge of the Preferred Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as the case may be, underlying this Income
PRIDES 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 Preferred
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.

         The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Income PRIDES Certificate
is registered as the owner of the Income PRIDES evidenced hereby for the purpose
of receiving payments of distributions

payable quarterly on the Preferred Securities, receiving payments of Contract
Adjustment Payments, if any, and any Deferred Contract Adjustment Payments,
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 shares of Common Stock.

         A copy of the Purchase Contract Agreement is available for inspection
at the offices of the Agent.

                   Form of Face of Growth PRIDES Certificate

     This Growth PRIDES Certificate certifies that ____________ is the
registered Holder of the number of Growth PRIDES set forth above.  Each Growth
PRIDES represents (i) a 1/40 undivided beneficial ownership interest, of a
Treasury Security having a principal amount at maturity equal to $1,000,
subject to the Pledge of such Treasury Security by such Holder pursuant to the
Pledge Agreement, and (ii) the rights and obligations of the Holder under one
Purchase Contract with Lincoln National Corporation, an Indiana corporation
(the "Company").  All capitalized terms used herein which are
defined in the Purchase Contract Agreement have the meaning set forth therein.

     Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Growth PRIDES evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder
under the Purchase Contract comprising a portion of such Growth PRIDES.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company, to sell, not later than
____________________, 2001 (the "Purchase Contract Settlement Date"), at a
price equal to $10 (the "Stated Amount"), a number of shares of Common stock,
no par value per share ("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
Growth PRIDES of which such Purchase Contract is a part, all as provided in the
Purchase Contract Agreement and more fully described on the reverse hereof.
The purchase price for the shares of Common Stock purchased pursuant to each
Purchase Contract evidenced hereby will be paid by application 
<PAGE>   18
of the Proceeds from the Treasury Securities pledged to secure the obligations
under such Purchase Contract in accordance with the terms of the Pledge
Agreement.

     The Company shall pay on each Payment Date in respect of each Purchase
Contract evidenced hereby an amount (the "Contract Adjustment Payments") equal
to __% per annum of the Stated Amount, computed on the basis of the actual
number of days elapsed in a year of 360 day year of twelve 30 day months, as the
case may be, subject to deferral at the option of the Company as provided in the
Purchase Contract Agreement and more fully described on the reverse hereof. Such
Contract Adjustment Payments, if any, shall be payable to the Person in whose
name this Growth PRIDES Certificate (or a Predecessor Growth PRIDES Certificate)
is registered at the close of business on the Record Date for such Payment Date.

     Contract Adjustment Payments, if any, will be payable at the office of the
Agent in The City of New York or, at the option of the Company, by check mailed
to the address of the Person entitled thereto as such address appears on the
Growth PRIDES Register.

     Reference is hereby made to the further provisions set forth on the reverse
hereof, which further provisions shall for all purposes have the same effect as
if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Agent by manual signature, this Growth PRIDES Certificate shall not be entitled
to any benefit under the Pledge Agreement or the Purchase Contract Agreement or
be valid or obligatory for any purpose.

     This is one of the Growth PRIDES referred to in the within-mentioned
Purchase Contract Agreement.


                                   By:  THE FIRST NATIONAL BANK OF
                                        CHICAGO, as Purchase Contract Agent



                                   By:  ___________________________________
                                            Authorized Signatory



                                  (Reverse of
                           Growth PRIDES Certificate)

     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of           , 1998 (as may be supplemented from time to
time, the "Purchase Contract Agreement") between the Company and The First
National Bank of Chicago, 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 Growth PRIDES Certificates are, and are to be, 
executed and delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company to sell, not later than
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 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 Amount is less than or equal to $   , then     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.

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


                                     -4-
<PAGE>   21

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
as reported by The New York Stock Exchange, Inc. (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, 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 "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 Growth PRIDES Certificate shall pay the Purchase Price for the
shares of 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 of the Pledged Treasury Securities underlying
such Holder's Growth PRIDES 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 shares of 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 shares of 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 Growth PRIDES 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 Growth
PRIDES.

     The Growth PRIDES Certificates are issuable only in registered form and
only in denominations of a single Growth PRIDES and any integral multiple
thereof. The transfer of any Growth PRIDES Certificate will be registered and
Growth PRIDES Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Growth PRIDES 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 Preferred Securities or the appropriate Applicable 


                                      -5-


<PAGE>   22
Ownership Interest of the Treasury Portfolio, as the case may be, for Treasury
Securities, thereby recreating Income PRIDES, shall be responsible for any fees
or expenses associated therewith.  Except as provided in the Purchase Contract
Agreement, for so long as the Purchase Contract underlying a Growth PRIDES
remains in effect, such Growth PRIDES shall not be separable into its
constituent parts, and the rights and obligations of the Holder of such Growth
PRIDES in respect of the Treasury Security and the Purchase Contract
constituting such Growth PRIDES may be transferred and exchanged only as a
Growth PRIDES.  A Holder of Growth PRIDES may create or recreate Income PRIDES
by delivering to the Collateral Agent Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, with a Stated Amount,
in the case of such Preferred 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 of the Treasury Portfolio, equal to the aggregate principal amount of
the Pledged Treasury Securities in exchange for the release of such Pledged
Treasury Securities in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement.  From and after such substitution, the
Holder's Security shall be referred to as an "Income PRIDES."  Such
substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, the equivalent
aggregate principal amount outstanding under this Growth PRIDES Certificate
shall not exceed $ ________.  All such adjustments to the equivalent aggregate
principal amount of this Growth PRIDES Certificate shall be duly recorded by
placing an appropriate notation on the Schedule attached hereto.

     A Holder of an Income PRIDES may create or recreate a Growth PRIDES by
delivering to the Collateral Agent Treasury Securities in an aggregate
principal amount equal to the aggregate Stated Amount of the Pledged Preferred
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 Preferred Securities or
the appropriate Applicable Ownership Interest of 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 Growth PRIDES may be
effected only in multiples of 40 Income PRIDES for 40 Growth PRIDES; provided,
however, if a Tax Event Redemption has occurred and the Treasury Portfolio has
become a component of the Income PRIDES, a Holder may make such Collateral
Substitution in integral multiples of 1,600,000 Income PRIDES for 1,600,000
Growth PRIDES.

     Subject to the next succeeding paragraph, the Company shall pay, on each
Payment Date, the Contract Adjustment Payments, if any, payable in respect of
each Purchase Contract to the Person in whose name the Growth PRIDES
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date.  Contract Adjustment
Payments, if any, will be payable at the office of the Agent in The City of New
York or, at the option of the Company, by check mailed to the address of the
Person entitled thereto at such address as it appears on the Growth PRIDES
Register. 


                                     -6-
<PAGE>   23
     The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) as provided in the
Purchase Contract Agreement. Any Contract Adjustment Payments, if any, so
deferred shall bear additional Contract Adjustment Payments thereon at the rate
of     % per annum (computed on the basis of a 360 day year of twelve 30 day
months), compounding on each succeeding Payment Date, until paid in full (such
deferred installments of Contract  Adjustment Payments, if any, together with
the additional Contract Adjustment Payments accrued thereon, are referred
to herein as the "Deferred Contract Adjustment Payments"). Deferred Contract
Adjustment Payments shall be due on the next succeeding Payment Date except to
the extent that payment is deferred pursuant to the Purchase Contract
Agreement. No Contract Adjustment Payments, if any, may be deferred to a date
that is after the Purchase Contract Settlement Date.

     In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until the Purchase
Contract Settlement Date, the Holder of this Growth PRIDES Certificate will
receive on the Purchase Contract Settlement Date, in lieu of a cash payment, a
number of Shares of Common Stock equal to (x) the aggregate amount of Deferred
Contract Adjustment Payments payable to the Holder of the Growth PRIDES
Certificate divided by (y) the Applicable Market Value.

     In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then, until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital
stock or make guarantee payments with respect to the foregoing (other than (i)
purchases or acquisitions of shares of capital stock of the Company in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security outstanding on the date of such event 
requiring the Company to purchase capital stock of the Company, (ii) as a
result of a reclassification of the Company's capital stock or the      
exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock, (iii) the purchase
of fractional interests in shares of the Company's capital stock pursuant to
the conversion or exchange provisions of the Company's capital stock or the
security being converted or exchanged, (iv) dividends or distributions in
capital stock of the Company (or rights to acquire capital stock) or
repurchases or redemptions of capital stock solely from the issuance or
exchange of capital stock or (v) redemptions or repurchases of any rights
outstanding under a shareholder rights plan or the declaration thereunder of a
dividend of rights in the future).

     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, if any, or any Deferred Contract Adjustment Payments, shall
immediately and automatically terminate, without the necessity of 

                                      -7-
<PAGE>   24
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 Growth PRIDES 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
Growth PRIDES Certificate, the Holder of this Growth PRIDES Certificate shall
deliver this Growth PRIDES 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, an amount equal to the Contract
Adjustment Payments, if any, payable on such Payment Date with respect to such
Purchase Contracts.  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 Growth
PRIDES as to which Early Settlement is effected equal to ______ shares of
Common Stock per Purchase Contract (the "Early Settlement Rate"); provided
however, that upon the Early Settlement of the Purchase Contracts, the Holder
thereof will forfeit the right to receive any Deferred Contract Adjustment
Payments on such Purchase Contracts.  The Early Settlement Rate 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 Growth PRIDES 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
Growth PRIDES 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 Growth PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Growth

                                      -8-
<PAGE>   25
PRIDES 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 its behalf as its attorney-in-fact, and consents to the Pledge of
the Treasury Securities underlying this Growth PRIDES 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.

         (d)     Notwithstanding anything herein to the contrary, the
Administrative Trustees are authorized and directed to conduct the affairs of
the Trust and to operate the Trust so that the Trust will not be deemed to be
an "investment company" required to be registered under the 1940 Act or taxed
as a corporation for United States Federal income tax purposes and so that the
Debentures will be treated as indebtedness of the Depositor for United States
Federal income tax purposes.  In this connection, the Depositor and the
Administrative Trustees are authorized to take any action, not inconsistent
with applicable law, the Certificate of Trust or this Trust Agreement, that
each of the Depositor and the Administrative Trustees determines in their
discretion to be necessary or desirable for such purposes, as long as such
action does not adversely affect in any material respect the interests of the
holders of the Preferred Securities.

Property Trustee (in its capacity as such) and shall be held and administered
by the Property Trustee for the benefit of the Trust and the Securityholders in
accordance with this Trust Agreement.

withdrawals from the Payment Account in accordance with this Trust Agreement.

                                  ARTICLE IV

                    CERTAIN TERMS OF THE TRUST SECURITIES

SECTION 4.1  DISTRIBUTIONS.

         (a)     Distributions on the Trust Securities shall be cumulative, and
will accumulate whether or not there are funds of the Trust available for the
payment of Distributions.  Distributions shall accrue from August 10, 1998, and
shall be payable quarterly in arrears on February 16, May 16, August 16 and
November 16 of each year, commencing on November 16, 1998, except as otherwise
described below.  The Depositor has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not extending, in the aggregate, beyond the
maturity date of the Debentures (each an "Extension Period").  During such
Extension Period no interest shall be due and payable on the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite
such deferral, quarterly Distributions will continue to accumulate at the rate
of ____% until __________ 15, 2001, and at the Reset Rate thereafter, compounded
quarterly during any such Extension Period (to the extent permitted by
applicable law).  Payments of accrued Distributions will be payable to Holders
as they appear on the books and records of the Trust on the first record date
after the end of the Extension Period.  Upon the termination of any Extension
Period and the payment of all amounts then due, the Depositor may commence a
new Extension Period; provided that such Extension Period together with all
such previous and further extensions thereof may not exceed beyond the maturity
date of the Debentures.  If any date on which a Distribution is otherwise
payable on the Trust Securities is not a Business Day, then the payment of such
Distribution shall be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of any such delay) except
that, if such Business Day is in the next succeeding calendar year, payment of
such Distribution shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date (each date on
which distributions are payable in accordance with this Section 4.1(a), a
"Distribution Date").

         (b)     The Trust Securities represent undivided beneficial interests
in the Trust Property, and, as a practical matter, the Distributions on the
Trust Securities shall be initially payable at a rate of ______% per annum (the
"Coupon Rate") of the Liquidation Amount of the Trust Securities until _________
15, 2001, and at the Reset Rate thereafter.  Distributions in arrears for more
than one quarter will accumulate and compound quarterly at the rate of ____%
until ____________ 15, 2001, and at the Reset Rate thereafter (to the extent
permitted by applicable law).  The term "Distributions" as used herein includes
such cash distributions and any such accumulated distributions that are payable
unless otherwise stated.  A Distribution is payable only to the extent that
payments are made in respect of the Debentures held by the Property Trustee and
to the extent the Property Trustee has funds available therefor.  The amount of
Distributions payable for any full period shall be computed on the basis of a
360-day year of twelve 30-day months.  The amount of Distributions for any
partial period shall be computed on the basis of the number of days elapsed in
a 360-day year of twelve 30-day months.





                                     -21-
<PAGE>   27


         (c)     Distributions on the Trust Securities shall be made by the
Property Trustee from the Payment Account and shall be payable on each
Distribution Date only to the extent that the Trust has funds then on hand and
available in the Payment Account for the payment of such Distributions.

         (d)     Distributions on the Trust Securities will be payable to the
Holders thereof as they appear on the books and records of the Trust at the
close of business on the Business Day immediately preceding each of the relevant
payment dates for the Trust Securities.  Subject to any applicable laws and
regulations and the provisions of this Trust Agreement, each such payment in
respect of the Preferred Securities will be made as described under the heading
"Description of the Preferred Securities -- Book Entry Only Issuance -- The
Depository Trust Company" in the Prospectus Supplement dated August 10, 1998
(the "Prospectus Supplement") relating to the FELINE PRIDES offered by the
Depositor and the Trust pursuant to the Registration Statement on Form S-3 (File
Nos. 333-49201 and 333-49201-02) of the Depositor and certain of its Affiliates.
The relevant record dates for the Common Securities shall be the same record
dates as for the Preferred Securities.  If the Preferred Securities shall not
continue to remain in book-entry only form or are not in book-entry only form at
issuance, the relevant record dates for the Preferred Securities shall conform
to the rules of any securities exchange on which such securities are listed and,
if none, as shall be selected by the Administrative Trustees, which dates shall
be at least more than one, but less than 60 Business Days before the relevant
payment dates, which payment dates shall correspond to the interest payment
dates on the Debentures.  Distributions payable on any Trust Securities that are
not punctually paid on any Distribution payment date, as a result of the
Depositor having failed to make a payment under the Debentures, will cease to be
payable to the Person in whose name such Trust Securities are registered on the
relevant record date, and such defaulted Distribution will instead be payable to
the Person in whose name such Trust Securities are registered on the special
record date or other specified date determined in accordance with the Indenture.
If any date on which Distributions are payable on the Trust Securities is not a
Business Day, then payment of the Distribution payable on such date will be made
on the next succeeding day that is a Business Day (and without any interests or
other payment in respect of any such delay) except that, if such Business Day is
in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.  So long as the Holder of any Preferred Securities is
the Collateral Agent, the payment of Distributions on such Preferred Securities
held by the Collateral Agent will be made at such place and to such account as
may be designated by the Collateral Agent.

         (e)     The Coupon Rate on the Trust Securities (as well as the
interest rate on the Debentures) will be reset on the third Business Day
immediately preceding the Purchase Contract Settlement Date to the Reset Rate
(which Reset Rate will be in effect on and after the Purchase Contract
Settlement Date).  On the Reset Announcement Date, the Reset Spread and the
Two-Year Benchmark Treasury to be used to determine the Reset Rate will be
announced by the Depositor.  On the Business Day immediately following the
Reset Announcement Date, the Holders of Trust Securities will be notified of
such Reset Spread and Two-Year Benchmark





                                     -22-
<PAGE>   28

Treasury by the Depositor.  Such notice shall be sufficiently given to Holders
of Trust Securities if published in an Authorized Newspaper.

         (f)     Not later than seven calendar days nor more than 15 calendar
days prior to the Reset Announcement Date, the Depositor will notify DTC or its
nominee (or any successor Clearing Agency or its nominee) by first-class mail,
postage prepaid, to notify the Owners or Clearing Agency Participants holding
Preferred Securities, Income PRIDES or Growth PRIDES, of such Reset
Announcement Date and the procedures to be followed by such Holders of Income
PRIDES who intend to settle their obligation under the Purchase Contract with
separate cash.

         (g)     In the event that there is any money or other property held by
or for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata among the Holders of the Trust Securities.  A reference
herein to any payment, distribution or treatment as being "Pro Rata" shall mean
pro rata to each Holder of Trust Securities according to the aggregate
liquidation amount of the Trust Securities held by the relevant Holder in
relation to the aggregate liquidation amount of all Trust Securities
outstanding unless, in relation to a payment, an Event of Default under the
Indenture has occurred and is continuing, in which case any funds available to
make such payment shall be paid first to each Holder of the Preferred
Securities pro rata according to the aggregate liquidation amount of Preferred
Securities held by the relevant Holder relative to the aggregate liquidation
amount of all Preferred Securities outstanding, and only after satisfaction of
all amounts owed to the Holders of the Preferred Securities, to each Holder of
Common Securities pro rata according to the aggregate liquidation amount of
Common Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Common Securities outstanding.

SECTION 4.2  REDEMPTION; INVESTMENT COMPANY EVENT; TAX EVENT REDEMPTION.

         (a)     On each Debenture Redemption Date and on the stated maturity
of the Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at a redemption price (the "Redemption Price") per Trust Security
equal to the Liquidation Amount of such Trust Security, plus accumulated and
unpaid Distributions to the Redemption Date, plus the related amount of the
premium, if any, paid by the Depositor upon the concurrent redemption of a Like
Amount of Debentures.

         (b)     If an Investment Company Event shall occur and be continuing
the Administrative Trustees shall dissolve the Trust and, after satisfaction of
liabilities to creditors, cause Debentures held by the Property Trustee, having
an aggregate principal amount equal to the aggregate stated liquidation amount
of, with an interest rate the rate of ____%, if on or prior to ___________ 15,
2001, and the Reset Rate thereafter, and accrued and unpaid interest equal to
accrued and unpaid Distributions on, and having the same record date for
payment as the Trust Securities, to be distributed to the Holders of the Trust
Securities in liquidation of such Holders' interests in the Trust on a Pro Rata
basis, within 90 days following the occurrence of such Investment Company Event
(the "90 Day Period"); provided, however, that, if at the time there is
available to the Trust the opportunity to eliminate, within the 90 Day Period,
the Investment

Company Event by taking some Ministerial Action, the Administrative Trustees
will pursue such Ministerial Action in lieu of dissolution.

         (c)     If a Tax Event shall occur and be continuing, the Debentures
are, at the option of the Depositor, redeemable pursuant to a Tax Event
Redemption.  If the Depositor redeems the Debentures upon the occurrence and
continuance of a Tax Event, the proceeds from such redemption shall
simultaneously be applied by the Property Trustee to redeem the Trust
Securities (on a pro rata basis) having an aggregate stated liquidation amount
equal to the aggregate principal amount of the Debentures so redeemed at a
Redemption Price per Trust Security equal to the Redemption Amount plus any
accrued and unpaid distributions to the date of redemption.  If, following the
occurrence of a Tax Event, the Depositor exercises its option to redeem the
Debentures prior to ____________, 2001, the Depositor shall appoint the
Quotation Agent to assemble the Treasury Portfolio in consultation with the
Company.  The Property Trustee will distribute to the record Holder of the
Trust Securities the Redemption Price payable in liquidation of such Holder's
interests in the Trust.

         On and from the date fixed by the Administrative Trustees for a Tax
Event Redemption or any distribution of Debentures and dissolution of the
Trust: (i) the Trust Securities will no longer be deemed to be outstanding and
(ii) DTC or its nominee (or any successor Clearing Agency or its nominee) or
the record Holder of the Preferred Securities, will receive a registered global
certificate or certificates representing the Debentures to be delivered upon
such distribution and any certificates representing Trust Securities, except
for certificates representing Preferred Securities held by DTC or its nominee
(or any successor Clearing Agency or its nominee), will be deemed to represent
beneficial interests in the Debentures having an aggregate principal amount
equal to the aggregate stated liquidation amount of $25, with an interest rate
of ___% if on or prior to __________ 15, 2001, and at the Reset Rate thereafter,
and accrued and unpaid interest equal to accrued and unpaid Distributions on
such Trust Securities until such certificates are presented to the Depositor or
its agent for transfer or reissue.

         (d)     Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date to each Holder of Trust Securities to be
redeemed, at such Holder's address appearing in the Security Register.  All
notices of redemption shall state:

                 (i)      the Redemption Date;

                 (ii)     the Redemption Price;

                 (iii)    the CUSIP number;

                 (iv)     if less than all the Outstanding Trust Securities are
         to be redeemed, the identification and the total Liquidation Amount of
         the particular Trust Securities to be redeemed; and





                                     -24-
<PAGE>   30

                 (v)      that on the Redemption Date the Redemption Price will
         become due and payable upon each such Trust Security to be redeemed
         and that distributions thereon will cease to accrue on and after said
         date.

         (e)     The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Debentures.  Redemptions of the Trust Securities shall be made
and the Redemption Price shall be payable on each Redemption Date only to the
extent that the Trust has funds then on hand and available in the Payment
Account for the payment of such Redemption Price.

         (f)     If the Property Trustee gives a notice of redemption (which
notice shall be irrevocable) in respect of any Trust Securities, then, by 12:00
noon, New York City time, on the Redemption Date, subject to Section 4.2(e),
the Property Trustee will, so long as the Trust Securities are in
book-entry-only form, irrevocably deposit with the Clearing Agency for the
Trust Securities funds sufficient to pay the applicable Redemption Price and
will give such Clearing Agency irrevocable instructions and authority to pay
the Redemption Price to the holders thereof.  If the Trust Securities are no
longer in book-entry-only form, the Property Trustee, subject to Section
4.2(e), will irrevocably deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Trust Securities Certificates.  Notwithstanding the
foregoing, Distributions payable on or prior to the Redemption Date for any
Trust Securities called for redemption shall be payable to the Holders of such
Trust Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates.  If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the date of such deposit, all
rights of Securityholders holding Trust Securities so called for redemption
will cease, except the right of such Securityholders to receive the Redemption
Price and any Distribution payable on or prior to the Redemption Date, but
without interest, and such Securities will cease to be outstanding.  In the
event that any date on which any Redemption Price is payable is not a Business
Day, then payment of the Redemption Price payable on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay), except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case, with the same force and effect as if made
on such date.  In the event that payment of the Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused
and not paid either by the Trust or by the Depositor pursuant to the Guarantee,
Distributions on such Trust Securities will continue to accrue, at the then
applicable rate, from the Redemption Date originally established by the Trust
for such Trust Securities to the date such Redemption Price is actually paid,
in which case the actual payment date will be the date fixed for redemption for
purposes of calculating the Redemption Price.

         (g)     Payment of the Redemption Price on the Trust Securities shall
be made to the recordholders thereof as they appear on the Securities Register
for the Trust Securities on the relevant record date, which shall be one
Business Day prior to the relevant Redemption Date;





                                     -25-
<PAGE>   31

provided, however, that in the event that the Preferred Securities do not
remain in book-entry-only form, the relevant record date shall be the date
fifteen days prior to the relevant Redemption Date.

         (h)     Subject to Section 4.3(a), if less than all the Outstanding
Trust Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities.  The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to $25 or an integral multiple of $25 in excess
thereof) of the Liquidation Amount of Preferred Securities of a denomination
larger than $25.  The Property Trustee shall promptly notify the Security
Registrar in writing of the Preferred Securities selected for redemption and,
in the case of any Preferred Securities selected for partial redemption, the
Liquidation Amount thereof to be redeemed.  For all purposes of this Trust
Agreement, unless the context otherwise requires, all provisions relating to
the redemption of Preferred Securities shall relate, in the case of any
Preferred Securities redeemed or to be redeemed only in part, to the portion of
the Liquidation Amount of Preferred Securities that has been or is to be
redeemed.

SECTION 4.3        SUBORDINATION OF COMMON SECURITIES.

         (a)     Payment of Distributions on, and the Redemption Price of, the
Trust Securities, as applicable, shall be made, subject to Section 4.2(f), pro
rata among the Common Securities and the Preferred Securities based on the
Liquidation Amount of the Trust Securities; provided, however, that if on any
Distribution Date or Redemption Date any Event of Default resulting from a
Debenture Event of Default shall have occurred and be continuing, no payment of
any Distribution on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of
Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Distributions on all Outstanding Preferred Securities
for all Distribution periods terminating on or prior thereto, or in the case of
payment of the Redemption Price the full amount of such Redemption Price on all
Outstanding Preferred Securities, shall have been made or provided for, and all
funds immediately available to the Property Trustee shall first be applied to
the payment in full in cash of all Distributions on, or the Redemption Price
of, Preferred Securities then due and payable.

         (b)     In the case of the occurrence of any Event of Default
resulting from any Debenture Event of Default, the Holder of Common Securities
will be deemed to have waived any right to act with respect to any such Event
of Default under this Trust Agreement until the effect of all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated.  Until any such Event of Default under this Trust
Agreement with respect to the Preferred Securities has been so cured, waived or
otherwise eliminated, the





                                     -26-
<PAGE>   32

Property Trustee shall act solely on behalf of the Holders of the Preferred
Securities and not the Holder of the Common Securities, and only the Holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

SECTION 4.4  PAYMENT PROCEDURES.

         Payments of Distributions in respect of the Preferred Securities shall
be made by check mailed to the address of the Person entitled thereto as such
address shall appear on the Securities Register or, if the Preferred Securities
are held by a Clearing Agency, such Distributions shall be made to the Clearing
Agency in immediately available funds, which shall credit the relevant Persons'
accounts at such Clearing Agency on the applicable distribution dates.
Payments in respect of the Common Securities shall be made in such manner as
shall be mutually agreed between the Property Trustee and the Common
Securityholder.

SECTION 4.5  TAX RETURNS AND REPORTS.

         The Administrative Trustees shall prepare (or cause to be prepared),
at the Depositor's expense, and file all United States Federal, state and local
tax and information returns and reports required to be filed by or in respect
of the Trust.  In this regard, the Administrative Trustees shall (a) prepare
and file (or cause to be prepared and filed) the appropriate Internal Revenue
Service Form required to be filed in respect of the Trust in each taxable year
of the Trust and (b) prepare and furnish (or cause to be prepared and
furnished) to each Securityholder the appropriate Internal Revenue Service form
required to be provided on such form.  The Administrative Trustees shall
provide the Depositor and the Property Trustee with a copy of all such returns
and reports promptly after such filing or furnishing.  The Trustees shall
comply with United States Federal withholding and backup withholding tax laws
and information reporting requirements with respect to any payments to
Securityholders under the Trust Securities.

SECTION 4.6  PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

         Upon receipt under the Debentures of Additional Sums, the Property
Trustee shall promptly pay any taxes, duties or governmental charges of
whatsoever nature (other than withholding taxes) imposed on the Trust by the
United States or any other taxing authority.

SECTION 4.7  PAYMENTS UNDER INDENTURE.

         Any amount payable hereunder to any Holder of Preferred Securities
(and any Owner with respect thereto) shall be reduced by the amount of any
corresponding payment such Holder (and Owner) has directly received pursuant to
Section 5.8 of the Indenture.

SECTION 4.8  REPAYMENT AT OPTION OF HOLDERS.

         (a)     If a Failed Remarketing (as described in Section 5.4(b) of the
Purchase Contract Agreement and incorporated herein by reference) has occurred,
each holder of Trust Securities who holds such Trust Securities on the day
immediately following the Purchase Contract Settlement Date shall have the
right on the Business Day immediately following ___________, 2001 to require
the Trust to distribute its Pro Rata share of the Debentures to the Exchange
Agent and to require the Exchange Agent to put such Debentures to the Company
(the "Put Option") on behalf of such holders on _________ 1, 2001, upon at least
three Business Days' prior notice (the "Put Option Exercise Date"), at a
repayment price of $25 per Trust Security plus an amount equal to the accrued
and unpaid Distributions (including deferred distributions if any) thereon to
the date of payment (the "Put Option Repayment Price").

         (b)     The Exchange Agent shall obtain funds to pay the Put Option
Repayment Price of Trust Securities being repaid under the Put Option through
presentation by it to the Depositor in an aggregate principal amount equal to
the aggregate stated liquidation amount of such Trust Securities for repayment
on the Put Option Exercise Date at the Debenture Repayment Price.

         (c)     In order for the Trust Securities to be repaid on the Put
Option Exercise Date, the Trust must receive on or prior to 4:00 p.m. on the
third Business Day immediately preceding the Put Option Exercise Date, at the
Corporate Trust Office of the Property Trustee (which will in turn notify the
Exchange Agent), the Trust Securities to be repaid with the form entitled
"Option to Elect Repayment" on the reverse thereof or otherwise accompanying
such Preferred Security duly completed. Any such notice received by the Trust
shall be irrevocable. All questions as to the validity, eligibility (including
time of receipt) and acceptance of the Trust Securities for repayment shall be
determined by the Trust, whose determination shall be final and binding.

         (d)     Payment of the Put Option Repayment Price to Holders of Trust
Securities shall be made at the Corporate Trust Office of the Exchange Agent,
provided that the Depositor has paid the Exchange Agent a sufficient amount of
cash in connection with the related repayment of the Debenture no later than
1:00 p.m., New York City time, on the Put Option Exercise Date by check or wire
transfer in immediately available funds at such place and to such account as
may be designated by such Holders. If the Exchange Agent holds immediately
available funds sufficient to pay the Put Option Repayment Price of such Trust
Securities, then, immediately prior to the close of business on the Put Option
Exercise Date, such Trust Securities will cease to be outstanding and
distributions thereon will cease to accrue, whether or not Trust Securities are
delivered to the Property Trustee, and all other rights of the Holder in
respect of the Trust Securities, including the Holder's right to require the
Trust to repay such Trust Securities, shall terminate and lapse (other than the
right to receive the Put Option Repayment Price but without interest on such
Put Option Repayment Price). Neither the Administrative Trustees nor the Trust
shall be required to register or cause to be registered the transfer of any
Trust Securities for which repayment has been elected. If payment of the Put
Option Repayment Price in respect of Trust Securities is (i) improperly
withheld or refused and not paid either by the Exchange Agent





                                     -28-
<PAGE>   34

or by the Depositor as guarantor pursuant to the Securities Guarantee, or (ii)
not paid by the Exchange Agent as the result of an Event of Default with
respect to the Debentures presented for repayment as described in Section
6.6(b), Distributions on such Trust Securities will continue to accrue, from
the original Put Option Exercise Date to the actual date of payment, in which
case the actual payment date will be considered the Put Option Exercise Date
for purposes of calculating the Put Option Repayment Price.

         (e)     The Depositor will request, not later than seven nor more than
15 calendar days prior to _______, 2001 (the date on which some or all of the
Preferred Securities could be remarketed in the manner described in Section
5.4(b) of the Purchase Contract Agreement and incorporated herein by reference)
that DTC notify the Preferred Securities Owner as well as the Income PRIDES and
Growth PRIDES holders of such remarketing and of the procedures that must be
followed if a Preferred Securities Owner wishes to exercise such holder's
rights with respect to the Put Option.

SECTION 4.9  REMARKETING.

         (a)     The Depositor will request, not later than 15 nor more than 30
calendar days prior to the Remarketing Date, that the Clearing Agency notify
the Holders of Preferred Securities and the Holders of Income PRIDES and Growth
PRIDES of the Remarketing and of the procedures that must be followed if a
Holder of Preferred Securities wishes to exercise such Holder's rights with
respect to the Put Option if there is a Failed Remarketing.

         (b)     Not later than 5:00 P.M., New York City time, on the fifth
Business Day immediately preceding the Purchase Contract Settlement Date, each
Holder of the Preferred Securities may elect to have Preferred Securities held
by such Holder remarketed. Under Section 5.4 of the Purchase Contract
Agreement, Holders of Income PRIDES that do not give notice of intention to
make a Cash Settlement of their related Purchase Contracts shall be deemed to
have consented to the disposition of the Preferred Securities comprising a
component of such Income PRIDES.  Holders of Preferred Securities that are not
a component of Income PRIDES shall give notice of their election to have such
Preferred Securities remarketed to the Custodial Agent pursuant to the Pledge
Agreement. Any such notice shall be irrevocable after 5:00 P.M., New York City
time, on the fifth Business Day immediately preceding the Purchase Contract
Settlement Date and may not be conditioned upon the level at which the Reset
Rate is established.  Promptly after 5:30 P.M., New York City time, on such
fifth Business Day, the Property Trustee, based on the notices received by it
prior to such time (including notices from the Purchase Contract Agent as to
Purchase Contracts for which cash settlement has been elected), shall notify
the Trust, the Depositor and the Remarketing Agent of the number of Preferred
Securities to be tendered for purchase.

         (c)     If any Holder of Income PRIDES does not give a notice of its
intention to make a Cash Settlement or gives a notice of election to tender
Preferred Securities as described in Section 4.9(b), the Preferred Securities
of such Holder shall be deemed tendered,





                                     -29-
<PAGE>   35

notwithstanding any failure by such Holder to deliver or properly deliver such
Preferred Securities to the Remarketing Agent for purchase.

         (d)     The right of each Holder to have Preferred Securities tendered
for purchase shall be limited to the extent that (i) the Remarketing Agent
conducts a remarketing pursuant to the terms of the Remarketing Agreement, (ii)
Preferred Securities tendered have not been called for redemption, (iii) the
Remarketing Agent is able to find a purchaser or purchasers for tendered
Preferred Securities and (iv) such purchaser or purchasers deliver the purchase
price therefor to the Remarketing Agent.

         (e)     On the Remarketing Date, the Remarketing Agent shall use
commercially reasonable efforts to remarket at a price equal to approximately
100.5% of the aggregate liquidation amount thereof, Preferred Securities
tendered or deemed tendered for purchase.

         (f)     If none of the Holders elects to have Preferred Securities
held by them remarketed, the Reset Rate shall be the rate determined by the
Remarketing Agent, subject to the terms of the Remarketing Agreement, as the
rate that would have been established had a remarketing been held on the
Remarketing Date.

         (g)     If the Remarketing Agent has determined that it will be able
to remarket all Preferred Securities tendered or deemed tendered prior to 4:00
P.M., New York City time, on the Remarketing Date, the Remarketing Agent shall
determine the Reset Rate, which shall be the rate per annum (rounded to the
nearest one-thousandth (0.001) of one percent per annum) which the Remarketing
Agent determines, subject to the terms of the Remarketing Agreement, to be the
lowest rate per annum that will enable it to remarket all Preferred Securities
tendered or deemed tendered for remarketing.

         (h)     If, by 4:00 P.M., New York City time, on the Remarketing Date,
the Remarketing Agent is unable to remarket all Preferred Securities tendered
or deemed tendered for purchase, a failed remarketing ("Failed Remarketing")
shall be deemed to have occurred and the Remarketing Agent shall so advise by
telephone the Collateral Agent, Depositor, Property Trustee, Delaware Trustee
and Clearing Agency.

         (i)     By approximately 4:30 P.M., New York City time, on the
Remarketing Date, provided that there has not been a Failed Remarketing, the
Remarketing Agent shall advise, by telephone (i) the Collateral Agent,
Depositor, Property Trustee, Delaware Trustee and Clearing Agency of the Reset
Rate determined in the Remarketing and the number of Preferred Securities sold
in the remarketing, (ii) each purchaser (or the Clearing Agency Participant
thereof) of the Reset Rate and the number of Preferred Securities such
purchaser is to purchase and (iii) each purchaser to give instructions to its
Clearing Agency Participant to pay the purchase price on the Purchase Contract
Settlement Date in same day funds against delivery of the Preferred Securities
purchased through the facilities of the Clearing Agency.





                                     -30-
<PAGE>   36

         (j)     In accordance with the Clearing Agency's normal procedures, on
the Purchase Contract Settlement Date, the transactions described above with
respect to each Preferred Security tendered for purchase and sold in the
remarketing shall be executed through the Clearing Agency, and the accounts of
the respective Clearing Agency Participants shall be debited and credited and
such Preferred Securities delivered by book entry as necessary to effect
purchases and sales of such Preferred Securities. The Clearing Agency shall
make payment in accordance with its normal procedures.

         (k)     If any Holder selling Preferred Securities in the remarketing
fails to deliver such Preferred Securities, the Clearing Agency Participant of
such selling Holder and of any other person that was to have purchased
Preferred Securities in the remarketing may deliver to any such other person a
number of Preferred Securities that is less than the number of Preferred
Securities that otherwise was to be purchased by such person. In such event,
the number of Preferred Securities to be so delivered shall be determined by
such Clearing Agency Participant, and delivery of such lesser number of
Preferred Securities shall constitute good delivery.

         (l)     The Remarketing Agent is not obligated to purchase any
Preferred Securities that would otherwise remain unsold in a remarketing.
Neither the Trust, any Trustee, the Depositor nor the Remarketing Agent shall
be obligated in any case to provide funds to make payment upon tender of
Preferred Securities for remarketing.

         (m)     The tender and settlement procedures set forth in this
Section, including provisions for payment by purchasers of Preferred Securities
in the remarketing, shall be subject to modification, notwithstanding any
provision to the contrary set forth herein, to the extent required by the
Clearing Agency or if the book-entry system is no longer available for the
Preferred Securities at the time of the remarketing, to facilitate the
tendering and remarketing of Preferred Securities in certificated form. In
addition, the Remarketing Agent may, notwithstanding any provision to the
contrary set forth herein, modify the settlement procedures set forth herein in
order to facilitate the settlement process.

SECTION 5.1  INITIAL OWNERSHIP.

         Upon the formation of the Trust and the contribution by the Depositor

any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

SECTION 5.2  THE TRUST SECURITIES CERTIFICATES.

         The Preferred Securities Certificates shall be issued in minimum
denominations of $25 Liquidation Amount and integral multiples of $25 in excess

Certificates shall be issued in denominations of $25 Liquidation Amount and
integral multiples thereof.  The Trust Securities Certificates shall be
executed on behalf of the Trust by manual signature of at least one
Administrative Trustee.  Trust Securities Certificates bearing the manual
signatures of individuals who were, at the time when such signatures shall have
been affixed, authorized to sign on behalf of the Trust, shall be validly
issued and entitled to the benefits of this Trust Agreement, notwithstanding
that such individuals or any of them shall have ceased to be so authorized
prior to the delivery of such Trust Securities Certificates or did not hold
such offices at the date of delivery of such Trust Securities Certificates.  A
transferee of a Trust Securities Certificate shall become a Securityholder, and
shall be entitled to the rights and subject to the obligations of a
Securityholder hereunder, upon due registration of such Trust Securities
Certificate in such transferee's name pursuant to Sections 5.4, 5.11 and 5.13.

SECTION 5.3  EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.

         At each Time of Delivery, the Administrative Trustees shall cause
Trust Securities Certificates, in an aggregate Liquidation Amount as provided
in Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to
or upon the written order of the Depositor, signed by its chief executive
officer, its president, any executive vice president or any vice president,
treasurer or assistant treasurer or controller without further corporate action
by the Depositor, in authorized denominations.

SECTION 5.4  REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
             CERTIFICATES.

         The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register") in which, the
registrar designated by the Depositor (the "Securities Registrar"), subject to
such reasonable regulations as it may prescribe, shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided.  The Bank shall be the initial
Securities Registrar.

         Upon surrender for registration of transfer of any Preferred
Securities Certificate at the office or agency maintained pursuant to Section
5.8, the Administrative Trustees or any one of them shall execute and deliver,
in the name of the designated transferee or transferees, one or more new
Preferred Securities Certificates in authorized denominations of a like
aggregate Liquidation Amount dated the date of execution by such Administrative
Trustee or Trustees.

         The Securities Registrar shall not be required to register the
transfer of any Preferred Securities that have been called for redemption.  At
the option of a Holder, Preferred Securities Certificates may be exchanged for
other Preferred Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount upon surrender of the
Preferred Securities Certificates to be exchanged at the office or agency
maintained pursuant to Section 5.8.

         Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Property Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly
authorized in writing.  Each Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be cancelled and subsequently
disposed of by the Property Trustee in accordance with its customary practice.

         No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

SECTION 5.5  MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
             CERTIFICATES.

         If (a) any mutilated Trust Securities Certificate shall be surrendered
to the Securities Registrar, or if the Securities Registrar shall receive
evidence to its satisfaction of the destruction, loss or theft of any Trust
Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for delivery, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Trust Securities Certificate,
a new Trust Securities Certificate of like class, tenor and denomination.  In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Securities Registrar may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in connection therewith.  Any duplicate Trust Securities
Certificate issued pursuant to this Section shall constitute conclusive
evidence of an undivided beneficial interest in the assets of the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Trust
Securities Certificate shall be found at any time.

SECTION 5.6  PERSONS DEEMED SECURITYHOLDERS.

         The Administrative Trustees or the Securities Registrar shall treat
the Person in whose name any Trust Securities Certificate shall be registered
in the Securities Register as the owner of such Trust Securities Certificate
for the purpose of receiving distributions and for all other purposes
whatsoever, and neither the Trustees nor the Securities Registrar shall be
bound by any notice to the contrary.

SECTION 5.7  ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

         Trust Securities Certificate, and each Owner shall be deemed to have
agreed not to hold the Depositor, the Property Trustee or the Administrative
Trustees accountable by reason of the





                                     -33-
<PAGE>   39

disclosure of its name and address, regardless of the source from which such
information was derived.

SECTION 5.8  MAINTENANCE OF OFFICE OR AGENCY.

         The Administrative Trustees shall maintain in Chicago, Illinois, an
office or offices or agency or agencies where Preferred Securities Certificates
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Trustees in respect of the Trust Securities
Certificates may be served.  The Administrative Trustees initially designate
The First National Bank of Chicago, One First National Plaza, Suite 0126,
Chicago, Illinois 60670-0126; Attention:  Corporate Trust Department, as its
principal corporate trust office for such purposes.  The Administrative
Trustees shall give prompt written notice to the Depositor and to the
Securityholders of any change in the location of the Securities Register or any
such office or agency.

SECTION 5.9  APPOINTMENT OF PAYING AGENT.

         The Paying Agent shall make distributions to Securityholders from the
Payment Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the distributions referred to above.  The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect.  The Paying
Agent shall initially be the Bank, and any co-paying agent chosen by the Bank,
and acceptable to the Administrative Trustees and the Depositor.  Any Person
acting as Paying Agent shall be permitted to resign as Paying Agent upon 30
days' written notice to the Administrative Trustees, the Property Trustee and
the Depositor.  In the event that the Bank shall no longer be the Paying Agent
or a successor Paying Agent shall resign or its authority to act be revoked,
the Administrative Trustees shall appoint a successor that is acceptable to the
Property Trustee and the Depositor to act as Paying Agent (which shall be a
bank or trust company).  The Administrative Trustees shall cause such successor
Paying Agent or any additional Paying Agent appointed by the Administrative
Trustees to execute and deliver to the Trustees an instrument in which such
successor Paying Agent or additional Paying Agent shall agree with the Trustees
that as Paying Agent, such successor Paying Agent or additional Paying Agent
will hold all sums, if any, held by it for payment to the Securityholders in
trust for the benefit of the Securityholders entitled thereto until such sums
shall be paid to such Securityholders.  The Paying Agent shall return all
unclaimed funds to the Property Trustee and upon removal of a Paying Agent such
Paying Agent shall also return all funds in its possession to the Property
Trustee.  The provisions of Sections 8.1, 8.3 and 8.6 herein shall apply to the
Bank also in its role as Paying Agent, for so long as the Bank shall act as
Paying Agent and, to the extent applicable, to any other paying agent appointed
hereunder.  Any reference in this Agreement to the Paying Agent shall include
any co-paying agent unless the context requires otherwise.

SECTION 5.10  OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

         At each Time of Delivery, the Depositor shall acquire and retain
beneficial and record ownership of the Common Securities.  To the fullest
extent permitted by law, other than a transfer in connection with a
consolidation or merger of the Depositor into another corporation, or any
conveyance, transfer or lease by the Depositor of its properties and assets
substantially as an entirety to any Person, pursuant to Section 8.1 of the
Indenture, any attempted transfer of the Common Securities shall be void.  The
Administrative Trustees shall cause each Common Securities Certificate issued
to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
TRANSFERABLE".

SECTION 5.11     BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
                 SECURITIES CERTIFICATE.

         (a)     The Preferred Securities Certificates, upon original issuance,
will be issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust.
Such Preferred Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no beneficial owner will receive a Definitive
Preferred Securities Certificate representing such beneficial owner's interest
in such Preferred Securities, except as provided in Section 5.13.  However,
notwithstanding anything to the contrary contained herein, the Preferred
Securities Certificates which are a component of the FELINE PRIDES shall be
issued in definitive registered form in the name of the Purchase Contract Agent
under the Purchase Contract Agreement.  Except for Definitive Preferred
Securities Certificates as specified herein, unless and until Definitive
Preferred Securities Certificates have been issued to beneficial owners
pursuant to Section 5.13:

                 (i)      the provisions of this Section 5.11(a) shall be in
full force and effect;

                 (ii)     the Securities Registrar and the Trustees shall be
         entitled to deal with the Clearing Agency for all purposes of this
         Trust Agreement relating to the Book-Entry Preferred Securities
         Certificates (including the payment of the Liquidation Amount of and
         Distributions on the Book-Entry Preferred Securities and the giving of
         instructions or directions to Owners of Book-Entry Preferred
         Securities) as the sole Holder of Book-Entry Preferred Securities and
         shall have no obligations to the Owners thereof;

                 (iii)    to the extent that the provisions of this Section
         5.11 conflict with any other provisions of this Trust Agreement, the
         provisions of this Section 5.11 shall control; and

                 (iv)     the rights of the Owners of the Book-Entry Preferred
         Securities Certificates shall be exercised only through the Clearing
         Agency and shall be limited to those established by law and agreements
         between such Owners and the Clearing Agency and/or the Clearing Agency
         Participants; provided, that solely for the purposes of determining
         whether the Holders of the requisite amount of Preferred Securities
         have





                                     -35-
<PAGE>   41

         voted on any matter provided for in this Trust Agreement, so long as
         Definitive Preferred Security Certificates have not been issued, the
         Trustees may conclusively rely on, and shall be protected in relying
         on, any written instrument (including a proxy) delivered to the
         Trustees by the Clearing Agency setting forth the Owners' votes or
         assigning the right to vote on any matter to any other Persons either
         in whole or in part.  Pursuant to the Certificate Depository
         Agreement, unless and until Definitive Preferred Securities
         Certificates are issued pursuant to Section 5.13, the initial Clearing
         Agency will make book-entry transfers among the Clearing Agency
         Participants and receive and transmit payments on the Preferred
         Securities to such Clearing Agency Participants.

         (b)     A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

SECTION 5.12  NOTICES TO CLEARING AGENCY.

         To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

SECTION 5.13  DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

         If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of a Debenture Event of
Default, Owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Property Trustee in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Property Trustee shall notify the
Clearing Agency and the Clearing Agency shall notify all Owners of Preferred
Securities Certificates and the other Trustees of the occurrence of any such
event and of the availability of the Definitive Preferred Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same.  Upon surrender to the Property Trustee of the typewritten Preferred
Securities Certificate or Certificates representing the Book Entry Preferred
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrative Trustees, or any one of them, shall execute
the Definitive Preferred Securities Certificates in accordance with the
instructions of the Clearing Agency.  Neither the Securities Registrar nor the
Trustees shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Preferred Securities Certificates, the Trustees
shall recognize the Holders of the Definitive Preferred Securities Certificates
as Securityholders.  The Definitive Preferred Securities Certificates shall be
printed,





                                     -36-
<PAGE>   42

lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.
Notwithstanding the foregoing, if and to the extent that any of the Preferred
Securities evidenced by the Definitive Preferred Securities Certificates
referred to in this paragraph are still pledged pursuant to the Pledge
Agreement, such Certificates shall be delivered to the Collateral Agent to be
held by the Collateral Agent as collateral pledged pursuant to the Pledge
Agreement.

SECTION 5.14  RIGHTS OF SECURITYHOLDERS.

         (a)     The legal title to the Trust Property is vested exclusively in
the Property Trustee (in its capacity as such) in accordance with Section 2.9,
and the Securityholders shall not have any right or title therein other than
the undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement.  The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Securityholders against payment of the purchase price therefor
will be fully paid and nonassessable by the Trust.  The Holders of the Trust
Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the
State of Delaware.

         (b)     For so long as any Preferred Securities remain Outstanding,
if, upon a Debenture Event of Default, the Debenture Trustee fails or the
holders of not less than 25% in principal amount of the outstanding Debentures
fail to declare the principal of all of the Debentures to be immediately due
and payable, the Holders of at least 25% in Liquidation Amount of the Preferred
Securities then Outstanding shall have such right by a notice in writing to the
Depositor and the Debenture Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, provided that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
the Indenture.

         (c)     For so long as any Preferred Securities remain Outstanding,
if, upon a Debenture Event of Default, the Debenture Trustee fails to exercise
directly any remedy available to the Holders of the Debentures for 60 days, the
Holders of at least 25% in Liquidation Amount of the Preferred Securities then
Outstanding shall, to the fullest extent permitted by law, have the right to
directly institute proceedings for enforcement of payment to such Holders of
principal amount of or interest on the Debentures having a principal amount
equal to the Liquidation Amount of the Preferred Securities of such Holders.

                   ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

SECTION 6.1  LIMITATIONS ON VOTING RIGHTS.

         (a)     Except as provided in this Section, in Sections 5.2, 8.10 and
10.2 and in the Indenture and as otherwise required by law, no Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of
an association.

         (b)     So long as any Debentures are held by the Property Trustee,
the Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the
prior approval of the Holders of at least a majority in Liquidation Amount of
all Outstanding Preferred Securities, provided, however, that where a consent
under the Indenture would require the consent of each Holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee
without the prior written consent of each Holder of Preferred Securities.  The
Trustees shall not revoke any action previously authorized or approved by a
vote of the Holders of Preferred Securities, except by a subsequent vote of the
Holders of Preferred Securities.  The Property Trustee shall notify all Holders
of the Preferred Securities of any notice of default received from the
Debenture Trustee with respect to the Debentures.  In addition to obtaining the
foregoing approvals of the Holders of the Preferred Securities, prior to taking
any of the foregoing actions, the Trustees shall, at the expense of the
Depositor, obtain an Opinion of Counsel experienced in such matters to the
effect that the Trust will not be classified as an association taxable as a
corporation for United States Federal income tax purposes on account of such
action.

         (c)     If any proposed amendment to the Trust Agreement provides for,
or the Trustees otherwise propose to effect, (i) any action that would
adversely affect in any material respect the powers, preferences or special
rights of the Preferred Securities, whether by way of amendment to the Trust
Agreement or otherwise, or (ii) the dissolution, winding-up or termination of
the Trust, other than pursuant to the terms of this Trust Agreement, then the
Holders of Outstanding Preferred Securities as a class will be entitled to vote
on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of the Holders of at least a majority in
Liquidation Amount of the Outstanding Preferred Securities.  No amendment to
this Trust Agreement may be made if, as a result of such amendment, the Trust
would be





                                     -38-
<PAGE>   44

classified as an association taxable as a corporation for United States federal
income tax purposes.

SECTION 6.2  NOTICE OF MEETINGS.

         Notice of all meetings of the Preferred Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting.  At any such meeting, any business properly before the meeting may be
so considered whether or not stated in the notice of the meeting.  Any
adjourned meeting may be held as adjourned without further notice.

SECTION 6.3  MEETINGS OF PREFERRED SECURITYHOLDERS.

         No annual meeting of Securityholders is required to be held.  The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% of the Preferred Securities (based upon their Liquidation Amount)
and the Administrative Trustees or the Property Trustee may, at any time in
their discretion, call a meeting of Preferred Securityholders to vote on any
matters as to which Preferred Securityholders are entitled to vote.

         Preferred Securityholders of record of 50% of the Outstanding
Preferred Securities (based upon their Liquidation Amount), present in person
or by proxy, shall constitute a quorum at any meeting of Securityholders.

         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding
more than a majority of the Preferred Securities (based upon their Liquidation
Amount) held by the Preferred Securityholders of record present, either in
person or by proxy, at such meeting shall constitute the action of the
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

SECTION 6.4  VOTING RIGHTS.

         Securityholders shall be entitled to one vote for each $25 of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.

SECTION 6.5  PROXIES, ETC.

         At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees
may direct, for verification prior to the time at which such vote shall be
taken.  Pursuant to a resolution of the Property Trustee, proxies may be
solicited in the name





                                     -39-
<PAGE>   45

of the Property Trustee or one or more officers of the Property Trustee.  Only
Securityholders of record shall be entitled to vote.  When Trust Securities are
held jointly by several persons, any one of them may vote at any meeting in
person or by proxy in respect of such Trust Securities, but if more than one of
them shall be present at such meeting in person or by proxy, and such joint
owners or their proxies so present disagree as to any vote to be cast, such
vote shall not be received in respect of such Trust Securities.  A proxy
purporting to be executed by or on behalf of a Securityholder shall be deemed
valid unless challenged at or prior to its exercise, and the burden of proving
invalidity shall rest on the challenger.  No proxy shall be valid more than
three years after its date of execution.

SECTION 6.6  SECURITYHOLDER ACTION BY WRITTEN CONSENT.

         Any action which may be taken by Securityholders at a meeting may be
taken without a meeting if Securityholders holding more than a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

SECTION 6.7  RECORD DATE FOR VOTING AND OTHER PURPOSES.

         For the purposes of determining the Securityholders who are entitled
to notice of and to vote at any meeting or by written consent, or to
participate in any distribution on the Trust Securities in respect of which a
record date is not otherwise provided for in this Trust Agreement, or for the
purpose of any other action, the Administrative Trustees may from time to time
fix a date, not more than 90 days prior to the date of any meeting of
Securityholders or the payment of a distribution or other action, as the case
may be, as a record date for the determination of the identity of the
Securityholders of record for such purposes.

SECTION 6.8  ACTS OF SECURITYHOLDERS.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders or Owners may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such
Securityholders or Owners in person or by an agent duly appointed in writing;
and, except as otherwise expressly provided herein, such action shall become
effective when such instrument or instruments are delivered to an
Administrative Trustee.  Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders or Owners 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 Trust Agreement and (subject
to Section 8.1) conclusive in favor of the Trustees, if made in the manner
provided in this Section.

         The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public





                                     -40-
<PAGE>   46

or other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to him the
execution thereof.  Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of his authority.  The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which any Trustee
receiving the same deems sufficient.

         The ownership of Preferred Securities shall be proved by the
Securities Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every
future Securityholder of the same Trust Security and the Securityholder of
every Trust Security 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 Trustees or the Trust in reliance thereon, whether
or not notation of such action is made upon such Trust Security.

         Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do
so with regard to all or any part of the Liquidation Amount of such Trust
Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any part of such liquidation
amount.

         If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder
or Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

         A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any person or entity.

SECTION 6.9  INSPECTION OF RECORDS.

         Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by
Securityholders during normal business hours for any purpose reasonably related
to such Securityholder's interest as a Securityholder.

case may be, to enter into or perform its obligations as one of the Trustees
under this Trust Agreement.

                                  THE TRUSTEES

SECTION 8.1  CERTAIN DUTIES AND RESPONSIBILITIES.

         (a)     The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee,
subject to the Trust Indenture Act.  Notwithstanding the foregoing, no
provision of this Trust Agreement shall require the Trustees to expend or risk
their own funds or otherwise incur any financial liability in the performance
of any of their duties hereunder, or in the exercise of any of their rights or
powers, if they shall have reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.  Whether or not therein expressly so provided, every
provision of this Trust Agreement relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section.  Nothing in this Trust Agreement shall be construed
to release the Property Trustee from liability for its own negligent action,
its own negligent failure to act, or its own willful





                                     -43-
<PAGE>   49

misconduct.  To the extent that, at law or in equity, an Administrative Trustee
has duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to the Securityholders, such Administrative Trustee shall not be
liable to the Trust or to any Securityholder for such Trustee's good faith
reliance on the provisions of this Trust Agreement.  The provisions of this
Trust Agreement, to the extent that they restrict the duties and liabilities of
the Administrative Trustees otherwise existing at law or in equity, are agreed
by the Depositor and the Securityholders to replace such other duties and
liabilities of the Administrative Trustees.

         (b)     All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and
proceeds from the Trust Property and only to the extent that there shall be
sufficient revenue or proceeds from the Trust Property to enable the Property
Trustee or a Paying Agent to make payments in accordance with the terms hereof.
Each Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in
respect of any Trust Security or for any other liability in respect of any
Trust Security.  This Section 8.1(b) does not limit the liability of the
Trustees expressly set forth elsewhere in this Trust Agreement and, in the case
of the Property Trustee, in the Trust Indenture Act.

         (c)     No provision of this Trust Agreement shall be construed to
relieve the Property Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                 (i)      the Property Trustee shall not be liable for any
         error of judgment made in good faith by an authorized officer of the
         Property Trustee, unless it shall be proved that the Property Trustee
         was negligent in ascertaining the pertinent facts;

                 (ii)     the Property Trustee shall not be liable with respect
         to any action taken or omitted to be taken by it in good faith in
         accordance with the direction of the Holders of not less than a
         majority in Liquidation Amount of the Trust Securities relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Property Trustee, or exercising any trust or power
         conferred upon the Property Trustee under this Trust Agreement;

                 (iii)    the Property Trustee's sole duty with respect to the
         custody, safe keeping and physical preservation of the Debentures and
         the Payment Account shall be to deal with such Property in a similar
         manner as the Property Trustee deals with similar property for its own
         account, subject to the protections and limitations on liability
         afforded to the Property Trustee under this Trust Agreement and the
         Trust Indenture Act;

                 (iv)     the Property Trustee shall not be liable for any
         interest on any money received by it except as it may otherwise agree
         with the Depositor; and money held by the Property Trustee need not be
         segregated from other funds held by it except in relation





                                     -44-
<PAGE>   50

         to the Payment Account maintained by the Property Trustee pursuant to
         Section 3.1 and except to the extent otherwise required by law; and

                 (v)      the Property Trustee shall not be responsible for
         monitoring the compliance by the Administrative Trustees or the
         Depositor with their respective duties under this Trust Agreement, nor
         shall the Property Trustee be liable for the default or misconduct of
         the Administrative Trustees or the Depositor.

SECTION 8.2  CERTAIN NOTICES.

         Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall
transmit, in the manner and to the extent provided in Section 10.8, notice of
such exercise to the Securityholders and the Property Trustee, unless such
exercise shall have been revoked.

SECTION 8.3  CERTAIN RIGHTS OF PROPERTY TRUSTEE.

         Subject to the provisions of Section 8.1:

         (a)     the Property Trustee may rely and shall be protected in acting
or refraining from acting in good faith upon any resolution, Opinion of
Counsel, certificate, written representation of a Holder or transferee,
certificate of auditors or any other certificate, statement, instrument,
opinion, report, notice, request, consent, order, appraisal, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

         (b)     if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to
which the Preferred Securityholders are entitled to vote under the terms of
this Trust Agreement, the Property Trustee shall deliver a notice to the
Depositor requesting written instructions of the Depositor as to the course of
action to be taken and the Property Trustee shall take such action, or refrain
from taking such action, as the Property Trustee shall be instructed in writing
to take, or to refrain from taking, by the Depositor and the Property Trustee
shall be fully protected in acting in accordance with such instructions;
provided, however, that if the Property Trustee does





                                     -45-
<PAGE>   51

not receive such instructions of the Depositor within ten Business Days after
it has delivered such notice, or such reasonably shorter period of time set
forth in such notice (which to the extent practicable shall not be less than
two Business Days), it may, but shall be under no duty to, take or refrain from
taking such action not inconsistent with this Trust Agreement as it shall deem
advisable and in the best interests of the Securityholders, in which event the
Property Trustee shall have no liability except for its own bad faith,
negligence or willful misconduct;

         (c)     any direction or act of the Depositor or the Administrative
Trustees contemplated by this Trust Agreement shall be sufficiently evidenced
by an Officers' Certificate;

         (d)     whenever in the administration of this Trust Agreement, the
Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence
of bad faith on its part, request and rely upon an Officers' Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

         (e)     the Property Trustee shall have no duty to see to any
recording, filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

         (f)     the Property Trustee may consult with counsel (which counsel
may be counsel to the Depositor or any of its Affiliates, and may include any
of its employees) and the advice of such counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or
omitted by it hereunder in good faith and in reliance thereon and in accordance
with such advice; the Property Trustee shall have the right at any time to seek
instructions concerning the administration of this Trust Agreement from any
court of competent jurisdiction;

         (g)     the Property Trustee shall be under no obligation to exercise
any of the rights or powers vested in it by this Trust Agreement at the request
or direction of any of the Securityholders pursuant to this Trust Agreement,
unless such Securityholders shall have offered to the Property Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

         (h)     the Property Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order,
approval, bond, debenture, note or other evidence of indebtedness or other
paper or document, unless requested in writing to do so by one or more
Securityholders, but the Property Trustee may make such further inquiry or
investigation into such facts or matters as it may see fit;

         (i)     the Property Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through its
agents or attorneys, provided





                                     -46-
<PAGE>   52

that the Property Trustee shall be responsible for its own negligence or
recklessness with respect to selection of any agent or attorney appointed by it
hereunder;

         (j)     whenever in the administration of this Trust Agreement the
Property Trustee shall deem it desirable to receive instructions with respect
to enforcing any remedy or right or taking any other action hereunder, the
Property Trustee (i) may request instructions from the Holders of the Trust
Securities which instructions may only be given by the Holders of the same
proportion in Liquidation Amount of the Trust Securities as would be entitled
to direct the Property Trustee under the terms of the Trust Securities in
respect of such remedy, right or action, (ii) may refrain from enforcing such
remedy or right or taking such other action until such instructions are
received, and (iii) shall be protected in acting in accordance with such
instructions; and

         (k)     except as otherwise expressly provided by this Trust
Agreement, the Property Trustee shall not be under any obligation to take any
action that is discretionary under the provisions of this Trust Agreement.

         No provision of this Trust Agreement shall be deemed to impose any
duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in
any jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation.  No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

SECTION 8.4  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Depositor, and the Trustees do not
assume any responsibility for their correctness.  The Trustees shall not be
accountable for the use or application by the Depositor of the proceeds of the
Debentures.

SECTION 8.5  MAY HOLD SECURITIES.

         Except as provided in the definition of the term "Outstanding" in
Article I, any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, subject to Sections 8.8 and 8.13, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

SECTION 8.6  COMPENSATION; INDEMNITY; FEES.

         The Depositor agrees:





                                     -47-
<PAGE>   53

         (a)     to pay to the Trustees from time to time reasonable
compensation for all services rendered by them hereunder (which compensation
shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

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

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

         The provisions of this Section 8.6 shall survive the termination of
this Trust Agreement or the resignation or removal of any Trustee.

         No Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

SECTION 8.7  CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

         (a)     There shall at all times be a Property Trustee hereunder.  The
Property Trustee shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000.  If any such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section, the combined
capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.
If at any time the Property Trustee with respect to the Trust Securities shall
cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

         (b)     There shall at all times be one or more Administrative
Trustees hereunder.  Each Administrative Trustee shall be either a natural
person who is at least 21 years of age or a legal entity that shall act through
one or more persons authorized to bind that entity.

         (c)     There shall at all times be a Delaware Trustee.  The Delaware
Trustee shall either be (i) a natural person who is at least 21 years of age
and a resident of the State of Delaware or (ii) a legal entity with its
principal place of business in the State of Delaware and that otherwise meets
the requirements of applicable Delaware law that shall act through one or more
persons authorized to bind such entity.

<PAGE>   54


SECTION 8.8  CONFLICTING INTERESTS.

         If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall
either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this
Trust Agreement.  Subject to the foregoing, the Depositor and any Trustee may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the
business of the Trust, and the Trust and the Holders shall have no rights by
virtue of this Trust Agreement in and to such independent ventures or the
income or profits derived therefrom, and the pursuit of any such venture, even
if competitive with the business of the Trust, shall not be deemed wrongful or
improper.  Neither the Depositor, nor any Trustee, shall be obligated to
present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and the Depositor or any Trustee shall have the right to
take for its own account (individually or as a partner or fiduciary) or to
recommend to others any such particular investment or other opportunity.  Any
Trustee may engage in any financial or other transaction with the Depositor or
any Affiliate of the Depositor, or may act as depository for, trustee or agent
for, or act on any committee or body of holders of, securities or other
obligations of the Depositor or its Affiliates.

SECTION 8.9  CO-TRUSTEES AND SEPARATE TRUSTEE.

         Unless an Event of Default shall have occurred and be continuing, at
any time or times, for the purpose of meeting the legal requirements of the
Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Depositor and the Administrative
Trustees, by agreed action of the majority of such Trustees, shall have power
to appoint, and upon the written request of the Administrative Trustees, the
Depositor shall for such purpose join with the Administrative Trustees in the
execution, delivery, and performance of all instruments and agreements
necessary or proper to appoint, one or more Persons approved by the Property
Trustee either to act as co-trustee, jointly with the Property Trustee, of all
or any part of such Trust Property, or to the extent required by law to act as
separate trustee of any such property, in either case with such powers as may
be provided in the instrument of appointment, and to vest in such Person or
Persons in the capacity aforesaid, any property, title, right or power deemed
necessary or desirable, subject to the other provisions of this Section.  If
the Depositor does not join in such appointment within 15 days after the
receipt by it of a request so to do, or in case a Debenture Event of Default
has occurred and is continuing, the Property Trustee alone shall have power to
make such appointment.  Any co-trustee or separate trustee appointed pursuant
to this Section shall either be (i) a natural person who is at least 21 years
of age and a resident of the United States or (ii) a legal entity with its
principal place of business in the United States that shall act through one or
more persons authorized to bind such entity.





                                     -49-
<PAGE>   55

         Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co- trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged and delivered
by the Depositor.

         Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms,
namely:

         (a)     The Trust Securities shall be executed and delivered and all
rights, powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be
exercised, solely by such Trustees and not by such co-trustee or separate
trustee.

         (b)     The rights, powers, duties, and obligations hereby conferred
or imposed upon the Property Trustee in respect of any property covered by such
appointment shall be conferred or imposed upon and exercised or performed by
the Property Trustee or by the Property Trustee and such co-trustee or separate
trustee jointly, as shall be provided in the instrument appointing such
co-trustee or separate trustee, except to the extent that under any law of any
jurisdiction in which any particular act is to be performed, the Property
Trustee shall be incompetent or unqualified to perform such act, in which event
such rights, powers, duties and obligations shall be exercised and performed by
such co-trustee or separate trustee.

         (c)     The Property Trustee at any time, by an instrument in writing
executed by it, with the written concurrence of the Depositor, may accept the
resignation of or remove any co-trustee or separate trustee appointed under
this Section, and, in case a Debenture Event of Default has occurred and is
continuing, the Property Trustee shall have power to accept the resignation of,
or remove, any such co-trustee or separate trustee without the concurrence of
the Depositor.  Upon the written request of the Property Trustee, the Depositor
shall join with the Property Trustee in the execution, delivery and performance
of all instruments and agreements necessary or proper to effectuate such
resignation or removal.  A successor to any co-trustee or separate trustee so
resigned or removed may be appointed in the manner provided in this Section.

         (d)     No co-trustee or separate trustee hereunder shall be
personally liable by reason of any act or omission of the Property Trustee or
any other trustee hereunder.

         (e)     The Property Trustee shall not be liable by reason of any act
of a co-trustee or separate trustee.

         (f)     Any Act of Holders delivered to the Property Trustee shall be
deemed to have been delivered to each such co-trustee and separate trustee.

SECTION 8.10       RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of any Trustee (the "Relevant Trustee") and
no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

         Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time with respect to the Trust Securities by giving written
notice thereof to the Securityholders.  If the instrument of acceptance by the
successor Trustee required by Section 8.11 shall not have been delivered to the
Relevant Trustee within 30 days after the giving of such notice of resignation,
the Relevant Trustee may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee with
respect to the Trust Securities.

         Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder.  If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust).  An Administrative Trustee may
be removed by the Common Securityholder at any time.

         If any Trustee shall resign, be removed or become incapable of acting
as Trustee, or if a vacancy shall occur in the office of any Trustee for any
cause, at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee
or Trustees with respect to the Trust Securities and the Trust, and the
retiring Trustee shall comply with the applicable requirements of Section 8.11.
If the Property Trustee or the Delaware Trustee shall resign, be removed or
become incapable of continuing to act as the Property Trustee or the Delaware
Trustee, as the case may be, at a time when a Debenture Event of Default shall
have occurred and be continuing, the Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the Preferred Securities
then Outstanding delivered to the retiring Relevant Trustee, shall promptly
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 8.11.

         If an Administrative Trustee shall resign, be removed or become
incapable of acting as Administrative Trustee, at a time when a Debenture Event
of Default shall have occurred and be continuing, the Common Securityholder by
Act of the Common Securityholder delivered to the Administrative Trustee shall
promptly appoint a successor Administrative Trustee or Administrative Trustees
with respect to the Trust Securities and the Trust, and such successor
Administrative Trustee or Trustees shall comply with the applicable
requirements of Section 8.11.  If no successor Relevant Trustee with respect to
the Trust Securities shall have been so





                                     -51-
<PAGE>   57

appointed by the Common Securityholder or the Preferred Securityholders and
accepted appointment in the manner required by Section 8.11, any Securityholder
who has been a Securityholder of Trust Securities 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 Relevant Trustee with
respect to the Trust Securities.

         The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.8 and shall give notice to
the Depositor.  Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Property
Trustee.

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 8.7).

SECTION 8.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee such
successor Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee
hereunder.

         In case of the appointment hereunder of a successor Relevant Trustee
with respect to the Trust Securities and the Trust, the retiring Relevant
Trustee and each successor Relevant Trustee with respect to the Trust
Securities shall execute and deliver an amendment hereto wherein each successor
Relevant Trustee shall accept such appointment and which (a) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and
to vest in, each successor Relevant Trustee all the rights, powers, trusts and
duties of the retiring Relevant Trustee with respect to the Trust Securities
and the Trust and (b) shall add to or change any of the provisions of this
Trust Agreement as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees of the same trust and that each such Relevant
Trustee shall be trustee of a trust or trusts hereunder





                                     -52-
<PAGE>   58

separate and apart from any trust or trusts hereunder administered by any other
such Relevant Trustee and upon the execution and delivery of such amendment the
resignation or removal of the retiring Relevant Trustee shall become effective
to the extent provided therein and each such successor Relevant Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Relevant Trustee with respect
to the Trust Securities and the Trust; but, on request of the Trust or any
successor Relevant Trustee such retiring Relevant Trustee shall duly assign,
transfer and deliver to such successor Relevant Trustee all Trust Property, all
proceeds thereof and money held by such retiring Relevant Trustee hereunder
with respect to the Trust Securities and the Trust.

         Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and
trusts referred to in the first or second preceding paragraph, as the case may
be.

         No successor Relevant Trustee shall accept its appointment unless at
the time of such acceptance such successor Relevant Trustee shall be qualified
and eligible under this Article.

SECTION 8.12  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Property Trustee or the Delaware
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which
such Relevant Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of such Relevant Trustee, shall
be the successor of such Relevant Trustee 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.

SECTION 8.13  PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR TRUST.

         If and when the Property Trustee or the Delaware Trustee shall be or
become a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities), the Property Trustee or the Delaware
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

SECTION 8.14  REPORTS BY PROPERTY TRUSTEE.

         (a)     Within 60 days after May 15 of each year commencing with May

                 (i)      its eligibility under Section 8.7 or, in lieu
         thereof, if to the best of its knowledge it has continued to be
         eligible under said Section, a written statement to such effect;

                 (ii)     a statement that the Property Trustee has complied
         with all of its obligations under this Trust Agreement during the
         twelve-month period (or, in the case of the initial report, the period
         since the Closing Date) ending with such May 15 or, if the Property
         Trustee has not complied in any material respect with such
         obligations, a description of such noncompliance; and

                 (iii)    any change in the property and funds in its
         possession as Property Trustee since the date of its last report and
         any action taken by the Property Trustee in the performance of its
         duties hereunder which it has not previously reported and which in its
         opinion materially affects the Trust Securities.

         (b)     In addition the Property Trustee shall transmit to
Securityholders such reports concerning the Property Trustee and its actions
under this Trust Agreement as may be required pursuant to the Trust Indenture
Act at the times and in the manner provided pursuant thereto.

         (c)     A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Property Trustee with each national
stock exchange, the Nasdaq National Market or such other interdealer quotation
system or self-regulatory organization upon which the Trust Securities are
listed or traded, with the Commission and with the Depositor.

SECTION 8.15  REPORTS TO THE PROPERTY TRUSTEE.

         The Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information
as required by Section 314 of the Trust Indenture Act (if any) and the
compliance certificate required by Section 314(a) of the Trust Indenture Act in
the form, in the manner and at the times required by Section 314 of the Trust
Indenture Act.

SECTION 8.16  EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

SECTION 8.17  NUMBER OF TRUSTEES.

         (a)     The number of Trustees shall be four, provided that the Holder
of all of the Common Securities by written instrument may increase or decrease
the number of Administrative Trustees.  The Property Trustee and the Delaware
Trustee may be the same person if the Property Trustee meets the applicable
requirements.

         (b)     If a Trustee ceases to hold office for any reason and the
number of Administrative Trustees is not reduced pursuant to Section 8.17(a),
or if the number of Trustees is increased pursuant to Section 8.17(a), a
vacancy shall occur.  The vacancy shall be filled with a Trustee appointed in
accordance with Section 8.10.

         (c)     The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust.  Whenever a vacancy in the number of Administrative
Trustees shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 8.10, the Administrative
Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Trust Agreement.

SECTION 8.18  DELEGATION OF POWER.

         (a)     Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the
age of 21 his or her power for the purpose of executing any documents
contemplated in Section 2.7(a), including any registration statement or
amendment thereto filed with the Commission, or making any other governmental
filing; and

         (b)     The Administrative Trustees shall have power to delegate from
time to time to such of their number or to the Depositor the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

SECTION 9.1  TERMINATION UPON EXPIRATION DATE.

Trust Property in accordance with Section 9.4.





                                     -55-
<PAGE>   61

SECTION 9.2  EARLY TERMINATION.

         The first to occur of any of the following events is an "Early
Termination Event":

         (a)     the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor;

         (b)     the written direction to the Property Trustee from the
Depositor at any time (which direction is optional and wholly within the
discretion of the Depositor) to terminate the Trust and distribute Debentures
to Securityholders in exchange for the Preferred Securities;

         (c)     the redemption of all of the Preferred Securities in
connection with the redemption of all the Debentures; and

         (d)     the entry of an order for dissolution of the Trust by a court
of competent jurisdiction.

SECTION 9.3  TERMINATION.

         The respective obligations and responsibilities of the Trustees and
the Trust created and continued hereby shall terminate upon the latest to occur
of the following: (a) the distribution by the Property Trustee to
Securityholders upon the liquidation of the Trust pursuant to Section 9.4, or
upon the redemption of all of the Trust Securities pursuant to Section 4.2, of
all amounts required to be distributed hereunder upon the final payment of the
Trust Securities; (b) the payment of any expenses owed by the Trust; and (c)
the discharge of all administrative duties of the Administrative Trustees,
including the performance of any tax reporting obligations with respect to the
Trust or the Securityholders.

SECTION 9.4  LIQUIDATION.

         (a)     If an Early Termination Event specified in clause (a), (b) or
(d) of Section 9.2 occurs or upon the Expiration Date, the Trust shall be
liquidated by the Trustees as expeditiously as the Trustees determine to be
possible by distributing, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, to each Securityholder a Like Amount of
Debentures, subject to Section 9.4(d).  Notice of liquidation shall be given by
the Property Trustee by first-class mail, postage prepaid mailed not later than
30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust
Securities at such Holder's address appearing in the Securities Register.  All
notices of liquidation shall:

                 (i)      state the Liquidation Date;

                 (ii)     state that from and after the Liquidation Date, the
         Trust Securities will no longer be deemed to be Outstanding and any
         Trust Securities Certificates not surrendered for exchange will be
         deemed to represent a Like Amount of Debentures; and





                                     -56-
<PAGE>   62


                 (iii)    provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if section 9.4(d) applies receive a Liquidation
         Distribution, as the Administrative Trustees or the Property Trustee
         shall deem appropriate.

         (b)     Except where Section 9.2(c) or 9.4(d) applies, in order to
effect the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c)     Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its reasonable efforts to have the Debentures listed on
the New York Stock Exchange or on such other exchange, interdealer quotation
system or self-regulatory organization as the Preferred Securities are then
listed, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on
which a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so
surrendered, no payments of interest or principal will be made to Holders of
Trust Securities Certificates with respect to such Debentures) and (v) all
rights of Securityholders holding Trust Securities will cease, except the right
of such Securityholders to receive Debentures upon surrender of Trust
Securities Certificates.

         (d)     In the event that, notwithstanding the other provisions of
this Section 9.4, whether because of an order for dissolution entered by a
court of competent jurisdiction or otherwise, distribution of the Debentures in
the manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as
the Property Trustee determines.  In such event, on the date of the
dissolution, winding-up or other termination of the Trust, Securityholders will
be entitled to receive out of the assets of the Trust available for
distribution to Securityholders, after satisfaction of liabilities to creditors
of the Trust as provided by applicable law, an amount equal to the Liquidation
Amount per Trust Security plus accumulated and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution").  If,
upon any such dissolution, winding up or termination, the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then, subject
to the next succeeding sentence, the amounts payable by the Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The holder of the Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution, winding-up or termination pro rata
(determined as aforesaid) with Holders of Preferred Securities, except that,





                                     -57-
<PAGE>   63

if a Debenture Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities.

SECTION 9.5  MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE
             TRUST.

         The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5.  At the request of the Depositor, with the consent of only
the Administrative Trustees and without the consent of the Property Trustee, the
Delaware Trustee or the holders of the Preferred Securities, the Trust may merge
with or into, consolidate, amalgamate, or be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
Depositor expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Debentures,
(iii) the Successor Securities are listed or traded, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on which the Preferred Securities are then listed
or traded, if any, (iv) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause the Preferred Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (v) such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities (including
any Successor Securities) in any material respect, (vi) such successor entity
has a purpose identical to that of the Trust, (vii) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Depositor has received an Opinion of Counsel to the effect that (a) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Trust nor such successor
entity will be required to register as an investment company under the 1940 Act
and (viii) the Depositor owns all of the Common Securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to any other entity or
permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger, replacement, conveyance,
transfer or lease would cause the Trust or the successor entity to be classified
as other than a grantor trust for United States Federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

SECTION 10.1  LIMITATION OF RIGHTS OF SECURITYHOLDERS.

         The death or incapacity of any person having an interest, beneficial
or otherwise, in Trust Securities shall not operate to terminate this Trust
Agreement, nor entitle the legal representatives or heirs of such person or any
Securityholder for such person, to claim an accounting, take any action or
bring any proceeding in any court for a partition or winding up of the
arrangements contemplated hereby, nor otherwise affect the rights, obligations
and liabilities of the parties hereto or any of them.

SECTION 10.2  AMENDMENT.

         (a)     This Trust Agreement may be amended from time to time by the
Trustees and the Depositor, without the consent of any Securityholders, (i) to
cure any ambiguity, correct or supplement any provision herein which may be
inconsistent with any other provision herein, or to make any other provisions
with respect to matters or questions arising under this Trust Agreement, which
shall not be inconsistent with the other provisions of this Trust Agreement, or
(ii) to modify, eliminate or add to any provisions of this Trust Agreement to
such extent as shall be necessary to ensure that the Trust will be classified
for United States Federal income tax purposes as a grantor trust at all times
that any Trust Securities are outstanding or to ensure that the Trust will not
be required to register as an investment company under the 1940 Act; provided,
however, that in the case of clause (i), such action shall not adversely affect
in any material respect the interests of any Securityholder, and any amendments
of this Trust Agreement shall become effective when notice thereof is given to
the Securityholders.

         (b)     Except as provided in Section 10.2(c) hereof, any provision of
this Trust Agreement may be amended by the Trustees and the Depositor with (i)
the consent of Trust Securityholders representing not less than a majority
(based upon Liquidation Amounts) of the Trust Securities then Outstanding and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax purposes or the Trust's exemption from status
of an investment company under the 1940 Act.

         (c)     In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
Trust Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount
of any Distribution required to be made in respect of the Trust Securities as
of a specified date or (a) restrict the right of a Securityholder to institute
suit for the enforcement of any such payment on or after such date;
notwithstanding any other provision herein, without the





                                     -59-
<PAGE>   65

unanimous consent of the Securityholders (such consent being obtained in
accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of this Section
10.2 may not be amended.

         (d)     Notwithstanding any other provisions of this Trust Agreement,
no Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an investment company under the 1940 Act or fail or cease to be
classified as a grantor trust for United States Federal income tax purposes.

         (e)     Notwithstanding anything in this Trust Agreement to the
contrary, without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

         (f)     In the event that any amendment to this Trust Agreement is
made, the Administrative Trustees shall promptly provide to the Depositor a
copy of such amendment.

         (g)     Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement which affects its
own rights, duties or immunities under this Trust Agreement.  The Property
Trustee shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

SECTION 10.3  SEPARABILITY.

         In case any provision in this Trust Agreement or in the Trust
Securities Certificates shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

SECTION 10.4  GOVERNING LAW.

         This Trust Agreement and the rights and obligations of each of the
Securityholders, the Trust and the Trustees with respect to this Trust
Agreement and the Trust Securities shall be construed in accordance with and
governed by the laws of the State of Delaware.

SECTION 10.5  PAYMENTS DUE ON NON-BUSINESS DAY.

         If the date fixed for any payment on any Trust Security shall be a day
that is not a Business Day, then such payment need not be made on such date but
may be made on the next succeeding day that is a Business Day (except as
otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and
effect as though made on the date fixed for such payment, and no interest shall
accrue thereon for the period after such date.

SECTION 10.9  AGREEMENT NOT TO PETITION.

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Securityholders, that at the
expense of the Depositor, it shall file an answer with the bankruptcy court or
otherwise properly contest the filing of such petition by the Depositor against
the Trust or the commencement of such action and raise the defense that the
Depositor has agreed in writing not to take such action and should be stopped
and precluded therefrom and such other defenses, if any, as counsel for the
Trustee or the Trust may assert.  The provisions of this Section 10.9 shall
survive the termination of this Trust Agreement.

trustee for the purposes of the Trust Indenture Act.

         (c)     If any provision hereof limits, qualifies or conflicts with

Agreement by any of the provisions of the Trust Indenture Act, such required
provision shall control.  If any provision of this Trust Agreement modifies or
excludes any provision of the Trust Indenture Act which may be so modified or
excluded, the latter provision shall be deemed to apply to this Trust Agreement
as so modified or excluded, as the case may be.

         (d)     The application of the Trust Indenture Act to this Trust
Agreement shall not affect the nature of the Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

                        [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Common Security will be fixed at a rate
per annum of __% until _________ 15, 2001, and at the Reset Rate thereafter (the
"Coupon Rate"), of the stated liquidation amount of $25 per Common Security,
such rate being the rate of interest payable on the Debentures to be held by
the Property Trustee. Distributions in arrears for more than one quarter will
accumulate and compound quarterly at the rate of __% until  _________ 15, 2001,
and at the Reset Rate thereafter (to the extent permitted by applicable law).
The term "Distributions" as used herein includes such cash distributions and
any such accumulated distributions unless otherwise stated. A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Property Trustee and to the extent the Property Trustee has funds
available therefor. The amount of Distributions payable for any full period
shall be computed on the basis of a 360-day year of twelve 30-day months.  The
amount of Distributions for any partial period shall be computed on the basis
of the number of days elapsed in a 360-day year of twelve 30-day months.

         Except as otherwise described below, distributions on the Common
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on February 16, May 16, August 16 and
November 16 of each year, commencing on November 16, 1998, to Holders of record
one Business Day prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures. The Depositor has
the right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not
exceeding, in the aggregate, beyond the maturity date of the Debentures (each
an "Extension Period") and, as a consequence of such deferral, Distributions
will also be deferred. Despite such deferral, quarterly Distributions will
continue to accumulate at the rate of __% until ___________ 15, 2001, and at the
Reset Rate thereafter, compounded quarterly during any such Extension Period
(to the extent permitted by applicable law). Payments of accrued Distributions
will be payable to Holders as they appear on the books and records of the Trust
on the first record date after the end of the Extension Period. Upon the
termination of any Extension Period and the payment of all amounts then due,
the Depositor may commence a new Extension Period; provided, that such
Extension Period together with all such previous and further extensions thereof
may not exceed beyond the maturity date of the Debentures.

         The Common Securities shall be redeemable as provided in the Trust
Agreement.

               This Preferred Security is a Global Certificate within the
meaning of the Trust Agreement hereinafter referred to and is registered in the
name of The Depository Trust Company (the "Depository") or a nominee of the
Depository.  This Preferred Security is exchangeable for Preferred Securities
registered in the name of a person other than the Depository or its nominee
only in the limited circumstances described in the Trust Agreement and no
transfer of this Preferred Security (other than a transfer of this Preferred
Security as a whole by the Depository to a nominee of the Depository or by a
nominee of the Depository to the Depository or another nominee of the
Depository) may be registered except in limited circumstances.

               Unless this Preferred Security is presented by an authorized
representative of The Depository Trust Company (55 Water Street, New York) to
Lincoln National Capital IV or its agent for registration of transfer, exchange
or payment, and any Preferred Security issued is registered in the name of Cede
& Co. or such other name as requested by an authorized representative of The
Depository Trust Company and any payment hereon is made to Cede & Co., ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY A PERSON IS
WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

                        [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Preferred Security will be fixed at an
initial rate per annum of __% until ___________ 15, 2001, and at the Reset Rate
thereafter (the "Coupon Rate"), of the stated liquidation amount of $25 per
Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for
more than one quarter will accumulate and compound quarterly at the rate of __%
until _____________ 15, 2001, and at the Reset Rate thereafter (to the extent

such cash distributions and any such accumulated distributions unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee and to the extent the
Property Trustee has funds available therefor. The amount of Distributions
payable for any full period shall be computed on the basis of a 360-day year of
twelve 30-day months.  The amount of Distributions for any partial period shall

Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on February 16, May 16, August 16 and

interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding, in the aggregate, beyond the maturity
date of the Debentures (each an "Extension Period") and, as a consequence of
such deferral, Distributions will also be deferred. Despite such deferral,
quarterly Distributions will continue to accumulate at the rate of ____% until
________ 15, 2001, and at the Reset Rate thereafter, compounded quarterly during
any such Extension Period (to the extent permitted by applicable law). Payments
of accrued Distributions will be payable to Holders as they appear on the books
and records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Depositor may commence a new Extension Period; provided,
that such Extension Period together with all such previous and further
extensions thereof may not exceed beyond the maturity date of the Debenture.

         The Preferred Securities shall be redeemable as provided in the Trust

SECTION 2.4      GLOBAL DEBENTURE.

         (a)     In connection with a Dissolution Event,

                      (i)         the Debentures in certificated form may be
         presented to the Trustee by the Property Trustee in exchange for a
         global Debenture in an aggregate principal amount equal to the
         aggregate principal amount of all outstanding Debentures (a "Global
         Debenture"), to be registered in the name of the Clearing Agency, or
         its nominee, and delivered by the Property Trustee to the Clearing
         Agency for crediting to the accounts of its participants pursuant to
         the instructions of the Administrative Trustees. The Company upon any
         such presentation shall execute a Global Debenture in such aggregate
         principal amount and deliver the same to the Trustee for
         authentication and delivery in accordance with the Indenture. Payments
         on the Debentures issued as a Global Debenture will be made to the
         Clearing Agency; and

                      (ii)        if any Preferred Securities are held in non
         book-entry certificated form, the Debentures in certificated form may
         be presented to the Trustee by the Property Trustee and any Preferred
         Security Certificate which represents Preferred Securities other than
         Preferred Securities held by the Clearing Agency or its nominee ("Non
         Book-Entry Preferred Securities") will be deemed to represent
         beneficial interests in the Debentures presented to the Trustee by the
         Property Trustee having an aggregate principal amount equal to the
         aggregate liquidation amount of the Non Book-Entry Preferred
         Securities until such Preferred Security Certificates are presented to
         the





                                      -4-
<PAGE>   8

         Security Registrar for transfer or reissuance at which time such
         Preferred Security Certificates will be cancelled and a Debenture,
         registered in the name of the holder of the Preferred Security
         Certificate or the transferee of the holder of such Preferred Security
         Certificate, as the case may be, with an aggregate principal amount
         equal to the aggregate liquidation amount of the Preferred Security
         Certificate cancelled, will be executed by the Company and delivered
         to the Trustee for authentication and delivery in accordance with the
         Indenture to such holder. On issue of such Debentures, Debentures with
         an equivalent aggregate principal amount that were presented by the
         Property Trustee to the Trustee will be deemed to have been cancelled.

         (b)     Unless and until it is exchanged for the Debentures in
registered form, a Global Debenture may be transferred, in whole but not in
part, only to another nominee of the Clearing Agency, or to a successor
Clearing Agency selected or approved by the Company or to a nominee of such
successor Clearing Agency.

         (c)     If at any time the Clearing Agency notifies the Company that
it is unwilling or unable to continue as a Clearing Agency or if at any time
the Clearing Agency for such series shall no longer be registered or in good
standing under the Securities Exchange Act of 1934, as amended, or other
applicable statute or regulation, and a successor Clearing Agency for such
series is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such condition, as the case may be,
the Company will execute, and, subject to Article III of the Indenture, the
Trustee, upon written notice from the Company, will authenticate and deliver
the Debentures in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Debenture in exchange for such Global Debenture. In
addition, the Company may at any time determine that the Debentures shall no
longer be represented by a Global Debenture. In such event the Company will
execute, and subject to Section 3.3 of the Base Indenture, the Trustee, upon
receipt of an Officer's Certificate evidencing such determination by the
Company, will authenticate and deliver the Debentures in definitive registered
form without coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global Debenture in
exchange for such Global Debenture. Upon the exchange of the Global Debenture
for such Debentures in definitive registered form without coupons, in
authorized denominations, the Global Debenture shall be cancelled by the
Trustee. Such Debentures in definitive registered form issued in exchange for
the Global Debenture shall be registered in such names and in such authorized
denominations as the Clearing Agency, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Securities to the Clearing Agency for delivery to the
Persons in whose names such Securities are so registered.

SECTION 2.5      INTEREST.

         (a)     Each Debenture will bear interest initially at the rate of ___
% per annum (the "Coupon Rate") from the original date of issuance until
_______, 2001, and at the Reset Rate thereafter until the principal thereof
becomes due and payable, and on any overdue principal and





                                      -5-
<PAGE>   9

(to the extent that payment of such interest is enforceable under applicable
law) on any overdue installment of interest at the Coupon Rate until _______,
2001 and at the Reset Rate thereafter, compounded quarterly, payable (subject
to the provisions of Article IV herein) quarterly in arrears on February 16,
May 16, August 16 and November 16 of each year (each, an "Interest Payment
Date") commencing on November 16, 1998, to the Person in whose name such
Debenture or any predecessor Debenture is registered, at the close of business
on the Regular Record Date for such interest installment, which, in respect of
(i) Debentures of which the Property Trustee is the Holder and the Preferred
Securities are in book-entry only form or (ii) a Global Debenture, shall be the
close of business on the Business Day next preceding that Interest Payment
Date.  Notwithstanding the foregoing sentence, if (i) the Debentures are held
by the Property Trustee and the Preferred Securities are no longer in
book-entry only form or (ii) the Debentures are not represented by a Global
Debenture, the Company may select a Regular Record Date for such interest
installment which shall be more than one Business Day but less than 60 Business
Days prior to an Interest Payment Date.

         (b)     The Coupon Rate on the Debentures will be reset on the third
Business Day immediately preceding the Purchase Contract Settlement Date to the
Reset Rate (which Reset Rate will become effective on and after the Purchase
Contract Settlement Date). On the tenth Business Day immediately preceding the
Purchase Contract Settlement Date, the Reset Announcement Date, the Reset
Spread and the relevant Two-Year Benchmark Treasury will be announced by the
Company. On the Business Day immediately following such Reset Announcement
Date, the Holders of Debentures will be notified of such Reset Spread and
Two-Year Benchmark Treasury by the Company. Such notice shall be sufficiently
given to such Holders of Debentures if published in an Authorized Newspaper.

         (c)     The amount of interest payable for any period will be computed
on the basis of twelve 30-day months and a 360-day year.  The amount of
interest payable for any partial period shall be computed on the basis of the
number of days elapsed in a 360-day year of twelve 30-day months.  In the event
that any date on which interest is payable on this Debenture is not a Business
Day, then a payment of the interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date the payment was originally payable.

                                  ARTICLE III
                          REDEMPTION OF THE DEBENTURES

SECTION 3.1      TAX EVENT REDEMPTION.

         If a Tax Event shall occur and be continuing, the Company may, at its
option, redeem the Debentures in whole (but not in part) at any time at a
Redemption Price per Debenture equal to the Redemption Amount plus accrued and
unpaid interest thereon, including Compounded Interest, if any, to the date of
such redemption (the "Tax Event Redemption Date"). If,





                                      -6-
<PAGE>   10

following the occurrence of a Tax Event, the Company exercises its option to
redeem the Debentures, then the proceeds of such redemption, if distributed to
the Property Trustee as the sole Holder of such Debentures, will be applied by
the Property Trustee to redeem Trust Securities having an aggregate liquidation
amount equal to the aggregate principal amount of the Debentures so redeemed,
at a Redemption Price per Trust Security equal to the Redemption Amount plus
accrued and unpaid distributions thereon to the date of such redemption.  If,
following the occurrence of a Tax Event prior to the Purchase Contract
Settlement Date, the Company exercises its option to redeem the Debentures, the
Company shall appoint the Quotation Agent to assemble the Treasury Portfolio in
consultation with the Company. Notice of any redemption will be mailed at least
30 days but not more than 60 days before the Tax Event Redemption Date to each
registered Holder of the Debentures to be prepaid at its registered address.
Unless the Company defaults in payment of the Redemption Price, on and after
the redemption date interest shall cease to accrue on such Debentures.

SECTION 3.2      REDEMPTION PROCEDURE FOR DEBENTURES.

         Payment of the Redemption Price to each Holder of Debentures shall be
made by the Company, no later than 12:00 noon, New York City time, on the Tax
Event Redemption Date, by check or wire transfer in immediately available funds
at such place and to such account as may be designated by each such Holder of
Debentures, including the Property Trustee or the Collateral Agent, as the case
may be. If the Trustee holds immediately available funds sufficient to pay the
Redemption Price of the Debentures (or, if the Company is acting as Paying
Agent or the Property Trustee has received the Redemption Price), then, on such
Tax Event Redemption Date, such Debentures will cease to be outstanding and
interest thereon will cease to accrue, whether or not such Debentures have been
received by the Company, and all other rights of the Holder in respect of the
Debentures shall terminate and lapse (other than the right to receive the
Redemption Price upon delivery of such Debentures but without interest on such
Redemption Price).

SECTION 3.3      NO SINKING FUND.

         The Debentures are not entitled to the benefit of any sinking fund.

SECTION 3.4      OPTION TO PUT DEBENTURES UPON A FAILED REMARKETING.

         If a Failed Remarketing (as described in Section 5.4(b) of the
Purchase Contract Agreement and incorporated herein by reference) has occurred,
each holder of Trust Securities who holds such Trust Securities on the day
immediately following the Purchase Contract Settlement Date, shall have the
right on the Business Day immediately following __________, 2001, upon at least
three Business Days' prior notice, to require the Trust to distribute their pro
rata share of Debentures to the Exchange Agent and to require the Exchange
Agent to put such Debentures to the Company (the "Put Option"), on behalf of
such holders on __________, 2001 (the "Put Option Exercise Date") at a
repayment price of $25 per Preferred Security plus an





                                      -7-
<PAGE>   11

amount equal to the accrued and unpaid Distributions (including deferred
distributions, if any) thereon to the date of payment (the "Debenture Repayment
Price").

SECTION 3.5      REPURCHASE PROCEDURE FOR DEBENTURES.

         (a)     In order for the Debentures to be repurchased on the Put
Option Exercise Date, the Company must receive on or prior to 5:00 p.m. New
York City time on the third Business Day immediately preceding the Put Option
Exercise Date, at the then principal executive offices of the Company, the
Debentures to be repurchased with the form entitled "Option to Elect Repayment"
on the reverse of or otherwise accompanying such Debentures duly completed. Any
such notice received by the Company shall be irrevocable.  All questions as to
the validity, eligibility (including time of receipt) and acceptance of the
Debentures for repayment shall be determined by the Company, whose
determination shall be final and binding.

         (b)     Payment of the Debenture Repayment Price to the Exchange Agent
shall be made through the Trustee, subject to the Trustee's receipt of payment
from the Company in accordance with the terms of the Indenture either through
the Trustee or the Company acting as Paying Agent, no later than 12:00 noon,
New York City time, on the Put Option Exercise Date, and to such account as may
be designated by the Exchange Agent. If the Trustee holds immediately available
funds sufficient to pay the Debenture Repayment Price of the Debentures
presented for repayment (or, if the Company is acting as Paying Agent and the
Property Trustee has received the Debenture Repayment Price), then, immediately
prior to the close of business on the Business Day immediately preceding the
Put Option Exercise Date, such Debentures will cease to be outstanding and
interest thereon will cease to accrue, whether or not such Debentures have been
received by the Company, and all other rights of the Holder in respect of the
Debentures, including the Holder's right to require the Company to repay such
Debentures, shall terminate and lapse (other than the right to receive the
Debenture Repayment Price upon delivery of such Debentures but without interest
on such Debenture Repayment Price). Neither the Trustee nor the Company will be
required to register or cease to be registered the transfer of any Debenture
for which repayment has been elected.

                                   ARTICLE IV
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1      EXTENSION OF INTEREST PAYMENT PERIOD.

         So long as no Event of Default has occurred or is continuing under the
Indenture, the Company shall have the right at any time during the term of the
Debentures, from time to time, to defer the payment of interest on such
Debentures for a period not extending, in the aggregate, beyond the maturity
date of the Debentures (each an "Extension Period"), during which Extension
Periods the Company shall have the right to make partial payments of interest
on any Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided that during any such
Extension Period, the Company will not, and will not permit any





                                      -8-
<PAGE>   12

Subsidiary of the Company to, (i) declare or pay any dividends or distributions
or redeem, purchase, acquire or make a liquidation payment with respect to, any
of the Company's outstanding capital stock or (ii) make any payment of
principal of, interest or premium, if any, on or repay, repurchase or redeem
any debt security of the Company that ranks pari passu with or junior in
interest to the Debentures or make any guarantee payments with respect to any
guarantee by the Company of the debt securities of any subsidiary of the
Company if such guarantee ranks pari passu with or junior in interest to the
Debentures (other than (a) dividends or distributions in Common Stock of the
Company, (b) redemptions or purchases of any rights pursuant to the Company's
Rights Plan, or any successor to such Rights Plan, and the declaration of a
dividend of such rights or the issuance of Stock under such plans in the
future, (c) payments under any Lincoln Guarantee (as defined in the Indenture),
and (d) purchases of Common Stock related to the issuance of Common Stock under
any of the Company's benefit plans for its directors, officers or employees).
Prior to the termination of any such Extension Period, the Company may further
extend the interest payment period, provided that no Extension Period shall
extend beyond the Maturity of the Debentures.  At the end of an Extension
Period, the Company shall pay all interest then accrued and unpaid (together
with the interest thereon at the rate of __% until ________, 2001 and at the
Reset Rate thereafter to the extent that payment of such interest is
enforceable under applicable law).  No interest shall be due and payable during
an Extension Period except at the end thereof.

SECTION 4.2      NOTICE OF EXTENSION.

         (a)     If the Property Trustee is the only registered Holder of the
Debentures at the time the Company selects an Extended Interest Payment Period,
the Company shall give written notice to the Administrative Trustees, the
Property Trustee and the Trustee of its selection of such Extended Interest
Payment Period one Business Day before the earlier of (i) the next succeeding
date on which Distributions on the Trust Securities issued by the Trust are
payable, or (ii) the date the Trust is required to give notice of the record

No. D-1                                                             $__________

                                                          CUSIP No. ___________

         LINCOLN NATIONAL CORPORATION, a corporation organized and existing
under the laws of Indiana (hereinafter called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to The First National Bank of
Chicago, as Property Trustee of Lincoln National Capital IV, or registered
assigns, the principal sum of ____________________________ dollars
($____________) on ____________, 2003.  The Company further promises to pay
interest on said principal sum from __________, 1998 or from the most recent
interest payment date (each such date, an "Interest Payment Date") on which
interest has been paid or duly provided for, quarterly (subject to deferral as
set forth herein) in arrears on February 16, May 16, August 16 and November 16
of each year, commencing on November 16, 1998, initially at the rate of ___%
per annum until _______, 2001, and at the Reset Rate thereafter until the
principal hereof shall have become due and payable, plus Additional Interest,
if any, until the principal hereof is paid or duly provided for or made
available for payment and on any overdue principal and (without duplication and
to the extent that payment of such interest is enforceable under applicable
law) on any overdue installment of interest at the rate of ___% until
_________, 2001, and at the Reset Rate thereafter, compounded quarterly.  The
interest rate will be reset on the third business day preceding __________,
2001 to the Reset Rate (as determined by the Reset Agent).  The amount of
interest payable for any period will be computed on the basis of twelve 30-day
months and a 360-day year.  The amount of interest payable for any partial
period shall be computed on the basis of the number of days elapsed in a
360-day year of twelve 30-day months.  In the event that any date on which
interest is payable on this Debenture is not a Business Day, then a payment of
the interest payable on such date will be made on the next succeeding day which
is a Business Day (and without any interest or other payment in respect of any
such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on the date the
payment was originally payable.  A "Business Day" shall mean any day other than
(i) a Saturday or Sunday, (ii) a day on which banking institutions in The City
of New York are authorized or required by law or executive order to remain
closed or (iii) a day on which the Corporate Trust Office of the Trustee or the
principal office of the Property Trustee under the Trust Agreement hereinafter
referred to for Lincoln National Capital IV is closed for business.  The
interest installment so payable, and punctually





                                      -12-
<PAGE>   16

paid or duly provided for, on any Interest Payment Date will, as provided in
the Indenture, be paid to the Person in whose name this Debenture (or one or
more Predecessor Securities, as defined in the Indenture) is registered at the
close of business on the Regular Record Date for such interest installment,
which in the case of a Global Security shall be the close of business on the
business day next preceding such Interest Payment Date; provided, however, if
pursuant to the terms of the Indenture the Debentures are no longer represented
by a Global Security, the Company may select such regular record date for such
interest installment which shall be more than one Business Day but less than 60
Business Days prior to an Interest Payment Date.  Any such interest installment
not so punctually paid or duly provided for shall forthwith cease to be payable
to the Holder on such Regular Record Date and may either be paid to the Person
in whose name this Debenture (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Debentures of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Debentures of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.

         So long as no Event of Default has occurred or is continuing under the
Indenture, the Company shall have the right at any time during the term of this
Debenture, from time to time, to defer the payment of interest on such
Debenture for a period not extending, in the aggregate, beyond the maturity
date of this Debenture (each an "Extension Period"), during which Extension
Periods the Company shall have the right to make partial payments of interest
on any Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided that during any such
Extension Period, the Company will not, and will not permit any Subsidiary of
the Company to, (i) declare or pay any dividends or distributions or redeem,
purchase, acquire or make a liquidation payment with respect to, any of the
Company's outstanding capital stock or (ii) make any payment of principal of,
interest or premium, if any, on or repay, repurchase or redeem any debt
security of the Company that ranks pari passu with or junior in interest to
this Debenture or make any guarantee payments with respect to any guarantee by
the Company of the debt securities of any subsidiary of the Company if such
guarantee ranks pari passu with or junior in interest to the Debentures (other
than (a) dividends or distributions in Common Stock of the Company, (b)
redemptions or purchases of any rights pursuant to the Company's Rights Plan,
or any successor to such Rights Plan, and the declaration of a dividend of such
rights or the issuance of Stock under such plans in the future, (c) payments
under any Lincoln Guarantee (as defined in the Indenture), and (d) purchases of
Common Stock related to the issuance of Common Stock under any of the Company's
benefit plans for its directors, officers or employees).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall extend beyond
the Maturity of this Debenture.  At the end of an Extension Period, the Company
shall pay all interest then accrued and unpaid (together with the interest
thereon at the rate of ___% until ________, 2001 and at the Reset Rate
thereafter to the extent that





                                      -13-
<PAGE>   17

payment of such interest is enforceable under applicable law).  No interest
shall be due and payable during an Extension Period except at the end thereof.

         Payment of the principal of (and premium, if any) and interest on this
Debenture will be made at the office or agency of the Company maintained for
that purpose in the United States, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company
payment of interest may be made (i) by check mailed to the address of the
Person entitled thereto as such address shall appear in the Securities Register
or (ii) by wire transfer in immediately available funds at such place and to
such account as may be designated by the Person entitled thereto as specified
in the Securities Register.  Notwithstanding the foregoing, so long as the
Holder of this Debenture is the Property Trustee or the Collateral Agent, the
payment of the principal of (and premium, if any) and interest on this
Debenture will be made at such place and to such account as may be designated
in writing by the Property Trustee or the Collateral Agent.

         The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and subject in right of payments to the
prior payment in full of all Senior Debt, and this Debenture is issued subject
to the provisions of the Indenture with respect thereto.  Each Holder of this
Debenture, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.  Each Holder hereof, by his acceptance hereof, waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Debt, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

         Reference is hereby made to the further provisions of this Debenture
set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Debenture shall not be entitled to any benefit  under the Indenture or be valid
or obligatory for any purpose.

                             [REVERSE OF DEBENTURE]

         This Debenture is one of a duly authorized issue of securities of the
Company (herein called the "Debentures"), issued and to be issued in one or
more series under a Junior Subordinated Indenture, dated as of May 1, 1996
(herein called the "Base Indenture"), between the Company and The First
National Bank of Chicago, as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), as supplemented by a First
Supplemental Indenture, dated August ___, 1998), (the Base Indenture as so
supplemented, the "Indenture"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Debentures, and of the terms upon which the
Debentures are, and are to be, authenticated and delivered.  This Debenture is
one of the series designated on the face hereof, limited in aggregate principal
amount to $____________.

         All terms used in this Debenture that are defined in the Indenture or
in the Amended and Restated Trust Agreement, dated as of August ___, 1998 (the
"Trust Agreement"), for Lincoln National Capital IV among Lincoln National
Corporation, as Depositor, and the Trustees named therein, shall have the
meanings assigned to them in the Indenture or the Trust Agreement, as the case
may be.

         If a Tax Event shall occur and be continuing, the Company may, at its
option, redeem Debentures in whole (but not in part) at any time at a
Redemption Price per Debenture equal to the Redemption Amount plus accrued and
unpaid interest thereon, including Compounded Interest (each as defined
herein), if any, to the Tax Event Redemption Date. The Redemption Price shall
be paid to each Holder of the Debenture by the Company, no later than 12:00
noon, New York City time, on the Tax Event Redemption Date, by check or wire
transfer in immediately available funds, at such place and to such account as
may be designated by each such Holder.

         The Debentures are not entitled to the benefit of any sinking fund.

         If a Failed Remarketing (as described in Section 5.4(b) of the
Purchase Contract Agreement and incorporated herein by reference) has occurred,
each holder of Trust Securities who holds such Trust Securities on the day
immediately following the Purchase Contract Settlement Date, shall have the
right on the Business Day immediately following __________, 2001, upon at least
three Business Days' prior notice, to require the Trust to distribute their pro
rata share of Debentures to the Exchange Agent and to require the Exchange
Agent to put such Debentures to the Company (the "Put Option"), on behalf of
such holders on __________, 2001 (the "Put Option Exercise Date") at a
repayment price of $25 per Preferred Security plus an amount equal to the
accrued and unpaid Distributions (including deferred distributions, if any)
thereon to the date of payment (the "Debenture Repayment Price").





                                      -16-
<PAGE>   20


         In order for the Debentures to be so repurchased, the Company must
receive, on or prior to 5:00 p.m. New York City Time on the third Business Day
immediately preceding the Put Option Exercise Date, at the then principal
executive offices of the Company, the Debentures to be repurchased with the
form entitled "Option to Elect Repayment" on the reverse of or otherwise
accompanying such Debentures duly completed. Any such notice received by the
Trustee shall be irrevocable. All questions as to the validity, eligibility
(including time of receipt) and acceptance of the Debentures for repayment
shall be determined by the Company, whose determination shall be final and
binding. The payment of the Debenture Repayment Price in respect of such
Debentures shall be made, either through the Trustee or the Company acting as
Paying Agent, no later than 12:00 noon, New York City time, on the Put Option
Exercise Date.

         If an Event of Default with respect to Debentures of this series shall
occur and be continuing, the principal of the Debentures of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

         The Indenture contains provisions for satisfaction, discharge and
defeasance at any time of the entire indebtedness of this Debenture upon
compliance by the Company with certain conditions set forth in the Indenture.

         The Indenture permits, with certain exceptions as therein provided,
the Company and the Trustee at any time to enter into a supplemental indenture
or indentures for the purpose of modifying in any manner the rights and
obligations of the Company and of the Holders of the Securities, with the
consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series to be affected by such supplemental
indenture.  The Indenture also contains provisions permitting Holders of
specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Debenture shall be conclusive
and binding upon such Holder and upon all future Holders of this Debenture and
of any Debenture issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Debenture.

         As provided in and subject to the provisions of the Indenture, if an
Event of Default with respect to Securities of this series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of this series may declare the principal amount (or, if the
Securities of this series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of this series) of all
the Securities of this series to be due and payable  immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), provided
that, in the case of the Securities of a series issued to a Lincoln Trust, if
upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series fail to declare
the principal of all the Securities of this series





                                      -17-
<PAGE>   21

to be immediately due and payable, the holders of at least 25% in aggregate
liquidation amount of the corresponding series of Preferred Securities then
outstanding shall have such right by a notice in writing to the Company and the
Trustee; and upon any such declaration such specified amount of and the accrued
interest (including any Additional Interest) on all the Securities of this
series shall become immediately due and payable, provided that the payment of
principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article Thirteen of the
Indenture.

         No reference herein to the Indenture and no provision of this
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and
premium, if any) and interest on this Debenture at the times, place and rate,
and in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Debenture is registrable in the
Securities Register, upon surrender of this Debenture for registration of
transfer at the office or agency of the Company maintained under Section 10.2
of the Indenture duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Securities Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Debentures of this series, of authorized
denominations and for the same aggregate principal amount, will be issued to
the designated transferee or transferees.  No service charge shall be made for
any such registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

         Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Debentures of this series are issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Debentures of this series are exchangeable for a like aggregate principal
amount of Debentures of such series of a different authorized denomination, as
requested by the Holder surrendering the same.

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, shareholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

SECTION 10.1     EFFECTIVENESS OF THIS ARTICLE.

         This Article Ten shall only become effective upon a Dissolution Event
which occurs prior to the Remarketing of the Preferred Securities pursuant to
this Agreement. Until such Dissolution Event, this Article Ten shall have no
effect.

SECTION 10.2     REMARKETING PROCEDURES.

         (a)     The Company will request, not later than 15 nor more than 30
calendar days prior to the Remarketing Date that the Clearing Agency notify the
Holders of the Debentures and the holders of Income PRIDES and Growth PRIDES of
the Remarketing and of the procedures that must be followed if a Holder of
Debentures wishes to exercise such Holder's rights with respect to the Put
Option if there is a Failed Remarketing.

         (b)     Not later than 5:00 P.M., New York City time, on the fifth
Business Day immediately preceding the Purchase Contract Settlement Date, each
Holder of the Debentures may elect to have Debentures held by such Holder
remarketed.  Under Section 5.4 of the Purchase Contract Agreement, Holders of
Income PRIDES that do not give notice of intention to make a Cash Settlement of
their related Purchase Contracts shall be deemed to have consented to the
disposition of the Debentures comprising a component of such Income PRIDES.
Holders of Debentures that are not a component of Income PRIDES shall give
notice of their election to have such Debentures remarketed to the Custodial
Agent pursuant to the Pledge Agreement. Any such notice shall be irrevocable
after 5:00 P.M., New York City time, on the fifth Business Day immediately
preceding the Purchase Contract Settlement Date and may not be conditioned upon
the level at which the Reset Rate is established. Promptly after 5:30 P.M., New
York City





                                      -22-
<PAGE>   26

time, on such fifth Business Day, the Property Trustee, based on the notices
received by it prior to such time (including notices from the Purchase Contract
Agent as to Purchase Contracts for which Cash Settlement has been elected),
shall notify the Trust, the Company and the Remarketing Agent of the number of
Debentures to be tendered for purchase.

         (c)     If any Holder of Income PRIDES does not give a notice of its
intention to make a Cash Settlement or gives a notice of election to tender
Debentures as described in Section 10.2(b), the Debentures of such Holder shall
be deemed tendered, notwithstanding any failure by such Holder to deliver or
properly deliver such Debentures to the Remarketing Agent for purchase.

         (d)     The right of each Holder to have Debentures tendered for
purchase shall be limited to the extent that (i) the Remarketing Agent conducts
a remarketing pursuant to the terms of the Remarketing Agreement, (ii)
Debentures tendered have not been called for redemption, (iii) the Remarketing
Agent is able to find a purchaser or purchasers for tendered Debentures and
(iv) such purchaser or purchasers deliver the purchase price therefor to the
Remarketing Agent.

         (e)     On the Remarketing Date, the Remarketing Agent shall use
commercially reasonable efforts to remarket at a price equal to approximately
100.5% of the aggregate principal amount thereof, Debentures tendered or deemed
tendered for purchase.

         (f)     If none of the Holders elect to have Debentures held by them
remarketed, the Reset Rate shall be the rate determined by the Remarketing
Agent, subject to the terms of the Remarketing Agreement, as the rate that
would have been established had a remarketing been held on the Remarketing
Date.

         (g)     If the Remarketing Agent has determined that it will be able
to remarket all Debentures tendered or deemed tendered prior to 4:00 P.M., New
York City time, on the Remarketing Date, the Remarketing Agent shall determine
the Reset Rate, which shall be the rate per annum (rounded to the nearest
one-thousandth (0.001) of one percent per annum) which the Remarketing Agent
determines, subject to the terms of the Remarketing Agreement, to be the lowest
rate per annum that will enable it to remarket all Debentures tendered or
deemed tendered for remarketing.

         (h)     If, by 4:00 P.M., New York City time, on the Remarketing Date,
the Remarketing Agent is unable to remarket all Debentures tendered or deemed
tendered for purchase, a failed remarketing ("Failed Remarketing") shall be
deemed to have occurred and the Remarketing Agent shall so advise by telephone
the Collateral Agent, Company, Property Trustee, Delaware Trustee and Clearing
Agency.

         (i)     By approximately 4:30 P.M., New York City time, on the
Remarketing Date, provided that there has not been a Failed Remarketing, the
Remarketing Agent shall advise, by telephone (i) the Collateral Agent, Company,
Property Trustee, Delaware Trustee and Clearing





                                      -23-

Agency of the Reset Rate determined in the Remarketing and the number of
Debentures sold in the remarketing, (ii) each purchaser (or the Clearing Agency
Participant thereof) of the Reset Rate and the number of Debentures such
purchaser is to purchase and (iii) each purchaser to give instructions to its
Clearing Agency Participant to pay the purchase price on the Purchase Contract
Settlement Date in same day funds against delivery of the Debentures purchased
through the facilities of the Clearing Agency.

         (j)     In accordance with the Clearing Agency's normal procedures, on
the Purchase Contract Settlement Date, the transactions described above with
respect to each Debenture tendered for purchase and sold in the remarketing
shall be executed through the Clearing Agency, and the accounts of the
respective Clearing Agency Participants shall be debited and credited and such
Debentures delivered by book entry as necessary to effect purchases and sales
of such Debentures. The Clearing Agency shall make payment in accordance with
its normal procedures.

         (k)     If any Holder selling Debentures in the remarketing fails to
deliver such Debentures, the Clearing Agency Participant of such selling Holder
and of any other person that was to have purchased Debentures in the
remarketing may deliver to any such other person a number of Debentures that is
less than the number of Debentures that otherwise was to be purchased by such
person. In such event, the number of Debentures to be so delivered shall be
determined by such Clearing Agency Participant, and delivery of such lesser
number of Debentures shall constitute good delivery.

         (l)     The Remarketing Agent is not obligated to purchase any
Debentures that would otherwise remain unsold in a remarketing. Neither the
Trust, any Trustee, the Company nor the Remarketing Agent shall be obligated in
any case to provide funds to make payment upon tender of Debentures for
remarketing.

         (m)     The tender and settlement procedures set in this Section 10.2,
including provisions for payment by purchasers of Debentures in the
remarketing, shall be subject to modification, notwithstanding any provision to
the contrary set forth herein, to the extent required by the Clearing Agency or
if the book-entry system is no longer available for the Debentures at the time
of the remarketing, to facilitate the tendering and remarketing of Debentures
in certificated form. In addition, the Remarketing Agent may, notwithstanding
any provision to the contrary set forth herein, modify the settlement
procedures set forth herein in order to facilitate the settlement process.

         LINCOLN NATIONAL CORPORATION, a corporation organized and existing
under the laws of Indiana (hereinafter called the "Company", which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to The First National Bank of Chicago, as
Property Trustee of Lincoln National Capital IV, or registered assigns, the
principal sum of ____________________________ dollars ($____________) on
____________, 2003. The Company further promises to pay interest on said
principal sum from __________, 1998 or from the most recent interest payment
date (each such date, an "Interest Payment Date") on which interest has been
paid or duly provided for, quarterly (subject to deferral as set forth herein)
in arrears on February 16, May 16, August 16 and November 16 of each year,
commencing on November 16, 1998, initially at the rate of ___% per annum until
_______, 2001, and at the Reset Rate thereafter until the principal hereof

shall have become due and payable, plus Additional Interest, if any, until the
principal hereof is paid or duly provided for or made available for payment and
on any overdue principal and (without duplication and to the extent that payment
of such interest is enforceable under applicable law) on any overdue installment
of interest at the rate of ___% until _________, 2001, and at the Reset Rate
thereafter, compounded quarterly. The interest rate will be reset on the third
business day preceding __________, 2001 to the Reset Rate (as determined by the
Reset Agent). The amount of interest payable for any period will be computed on
the basis of twelve 30-day months and a 360-day year. The amount of interest
payable for any partial period shall be computed on the basis of the number of
days elapsed in a 360-day year of twelve 30 day months. In the event that any
date on which interest is payable on this Debenture is not a Business Day, then
a payment of the interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date the payment was originally payable. A "Business Day" shall mean any
day other than (i) a Saturday or Sunday, (ii) a day on which banking
institutions in The City of New York are authorized or required by law or
executive order to remain closed or (iii) a day on which the Corporate Trust
Office of the Trustee or the principal office of the Property Trustee under the
Trust Agreement hereinafter referred to for Lincoln National Capital IV is
closed for business. The interest installment so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Debenture (or one or more
Predecessor Securities, as defined in the Indenture) is registered at the close
of business on the Regular Record Date for such interest installment, which in
the case of a Global Security shall be the close of business on the business day
next preceding such Interest Payment Date; provided, however, if pursuant to the
terms of the Indenture the Debentures are no longer represented by a Global
Security, the Company may select such regular record date for such interest
installment which shall be more than one Business Day but less than 60 Business
Days prior to an Interest Payment Date. Any such interest installment not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name this Debenture (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Debentures of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Debentures of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

         So long as no Event of Default has occurred or is continuing under the
Indenture, the Company shall have the right at any time during the term of this
Debenture, from time to time, to defer the payment of interest on such Debenture
for a period not extending, in the aggregate, beyond the maturity date of this
Debenture (each an "Extension Period"), during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued

                                       -2-

and unpaid (together with Additional Interest thereon to the extent permitted by
applicable law); provided that during any such Extension Period, the Company
will not, and will not permit any Subsidiary of the Company to, (i) declare or
pay any dividends or distributions or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's outstanding capital
stock or (ii) make any payment of principal of, interest or premium, if any, on
or repay, repurchase or redeem any debt security of the Company that ranks pari
passu with or junior in interest to this Debenture or make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any subsidiary of the Company if such guarantee ranks pari passu with or junior
in interest to the Debentures (other than (a) dividends or distributions in
Common Stock of the Company, (b) redemptions or purchases of any rights pursuant
to the Company's Rights Plan, or any successor to such Rights Plan, and the
declaration of a dividend of such rights or the issuance of Stock under such
plans in the future, (c) payments under any Lincoln Guarantee (as defined in the
Indenture), and (d) purchases of Common Stock related to the issuance of Common
Stock under any of the Company's benefit plans for its directors, officers or
employees). Prior to the termination of any such Extension Period, the Company
may further extend the interest payment period, provided that no Extension
Period shall extend beyond the Maturity of this Debenture. At the end of an
Extension Period, the Company shall pay all interest then accrued and unpaid
(together with the interest thereon at the rate of ___% until ________, 2001 and
at the Reset Rate thereafter to the extent that payment of such interest is
enforceable under applicable law). No interest shall be due and payable during
an Extension Period except at the end thereof.

         Payment of the principal of (and premium, if any) and interest on this
Debenture will be made at the office or agency of the Company maintained for
that purpose in the United States, in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Securities Register or (ii) by wire
transfer in immediately available funds at such place and to such account as may
be designated by the Person entitled thereto as specified in the Securities
Register. Notwithstanding the foregoing, so long as the Holder of this Debenture
is the Property Trustee or the Collateral Agent, the payment of the principal of
(and premium, if any) and interest on this Debenture will be made at such place
and to such account as may be designated in writing by the Property Trustee or
the Collateral Agent.

         The indebtedness evidenced by this Debenture is, to the extent provided
in the Indenture, subordinate and subject in right of payments to the prior
payment in full of all Senior Debt, and this Debenture is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this Debenture,
by accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his behalf to take such actions as may be
necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes. Each
Holder hereof, by his acceptance hereof, waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each
holder of Senior Debt, whether now outstanding or hereafter incurred,

                                       -3-

and waives reliance by each such holder upon said provisions.

         Reference is hereby made to the further provisions of this Debenture
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Debenture shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

                             [REVERSE OF DEBENTURE]

         This Debenture is one of a duly authorized issue of securities of the
Company (herein called the "Debentures"), issued and to be issued in one or more
series under a Junior Subordinated Indenture, dated as of May 1, 1996 (herein
called the "Base Indenture"), between the Company and The First National Bank of
Chicago, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), as supplemented by a First Supplemental
Indenture, dated August ___, 1998), (the Base Indenture as so supplemented, the
"Indenture"), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Trustee, the Company and the
Holders of the Debentures, and of the terms upon which the Debentures are, and
are to be, authenticated and delivered. This Debenture is one of the series
designated on the face hereof, limited in aggregate principal amount to
$____________.

         All terms used in this Debenture that are defined in the Indenture or
in the Amended and Restated Trust Agreement, dated as of August ___, 1998 (the
"Trust Agreement"), for Lincoln National Capital IV among Lincoln National
Corporation, as Depositor, and the Trustees named therein, shall have the
meanings assigned to them in the Indenture or the Trust Agreement, as the case
may be.

         If a Tax Event shall occur and be continuing, the Company may, at its
option, redeem Debentures in whole (but not in part) at any time at a Redemption
Price per Debenture equal to the Redemption Amount plus accrued and unpaid
interest thereon, including Compounded Interest (each as defined herein), if
any, to the Tax Event Redemption Date. The Redemption Price shall be paid to
each Holder of the Debenture by the Company, no later than 12:00 noon, New York
City time, on the Tax Event Redemption Date, by check or wire transfer in
immediately available funds, at such place and to such account as may be
designated by each such Holder.

         The Debentures are not entitled to the benefit of any sinking fund.

         If a Failed Remarketing (as described in Section 5.4(b) of the Purchase
Contract Agreement and incorporated herein by reference) has occurred, each
holder of Debentures who holds such Debentures on the day immediately following
The Purchase Contract Settlement Date, shall, upon at least three Business Days'
prior notice, have the right (the "Put Option") on the Business Day immediately
following ___________, 2001, to require the Trust to distribute their pro rata
share of Debentures to the Exchange Agent and to require the Exchange Agent to
put such Debentures, on behalf of such holders on ___________, 2001 (the "Put
Option Exercise Date") at a repayment price of $25 per Debenture plus an amount
equal to the accrued and unpaid Distributions (including deferred distributions,
if any) thereon to the date of payment (the "Debenture Repayment Price").


                                       -6-


<PAGE>   7



         In order for the Debentures to be so repurchased, the Company must
receive, on or prior to 5:00 p.m. New York City Time on the third Business Day
immediately preceding the Put Option Exercise Date, at the then principal
executive offices of the Company, the Debentures to be repurchased with the form
entitled "Option to Elect Repayment" on the reverse of or otherwise accompanying
such Debentures duly completed. Any such notice received by the Trustee shall be
irrevocable. All questions as to the validity, eligibility (including time of
receipt) and acceptance of the Debentures for repayment shall be determined by
the Company, whose determination shall be final and binding. The payment of the
Debenture Repayment Price in respect of such Debentures shall be made, either
through the Trustee or the Company acting as Paying Agent, no later than 12:00
noon, New York City time, on the Put Option Exercise Date.

         If an Event of Default with respect to Debentures of this series shall
occur and be continuing, the principal of the Debentures of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

         The Indenture contains provisions for satisfaction, discharge and
defeasance at any time of the entire indebtedness of this Debenture upon
compliance by the Company with certain conditions set forth in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose of modifying in any manner the rights and obligations
of the Company and of the Holders of the Securities, with the consent of the
Holders of not less than a majority in principal amount of the Outstanding
Securities of each series to be affected by such supplemental indenture. The
Indenture also contains provisions permitting Holders of specified percentages
in principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Debenture shall be conclusive and binding upon such Holder and
upon all future Holders of this Debenture and of any Debenture issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Debenture.

         As provided in and subject to the provisions of the Indenture, if an
Event of Default with respect to Securities of this series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of this series may declare the principal amount (or, if the
Securities of this series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of this series) of all
the Securities of this series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of a series issued to a Lincoln Trust, if upon an
Event of Default, the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities of this series fail to declare the
principal of all the Securities of this series

                                       -7-


<PAGE>   8



to be immediately due and payable, the holders of at least 25% in aggregate
liquidation amount of the corresponding series of Preferred Securities then
outstanding shall have such right by a notice in writing to the Company and the
Trustee; and upon any such declaration such specified amount of and the accrued
interest (including any Additional Interest) on all the Securities of this
series shall become immediately due and payable, provided that the payment of
principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article Thirteen of the
Indenture.

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Debenture at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Debenture is registrable in the Securities
Register, upon surrender of this Debenture for registration of transfer at the
office or agency of the Company maintained under Section 10.2 of the Indenture
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Debentures of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Debentures of this series are issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Debentures of this series are exchangeable for a like aggregate principal amount
of Debentures of such series of a different authorized denomination, as
requested by the Holder surrendering the same.

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, shareholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

an Event of Default has occurred (that has not been cured or waived pursuant to

       (d) No provision of this Guarantee Agreement shall be construed to
relieve the Guarantee Trustee from liability for its own negligent action, its
own negligent failure to act or its own willful misconduct, except that:

         (i)      prior to the occurrence of any Event of Default and after the

                        shall be determined solely by the express provisions of
                        this Guarantee Agreement, and the Guarantee Trustee
                        shall not be liable except for the performance of such
                        duties and obligations as are specifically set forth in
                        this Guarantee Agreement; and

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

         (ii)     the Guarantee Trustee shall not be liable for any error of
                  judgment made in good faith by a Responsible Officer of the
                  Guarantee Trustee, unless it shall be proved that the
                  Guarantee Trustee was negligent in ascertaining the pertinent
                  facts upon which such judgment was made;

         (iii)    the Guarantee Trustee shall not be liable with respect to any
                  action taken or omitted to be taken by it in good faith in
                  accordance with the direction of the Holders of not less than
                  a Majority in liquidation preference of the Preferred
                  Securities relating to the time, method and place of
                  conducting any proceeding for any remedy available to the

                  upon the Guarantee Trustee under this Guarantee Agreement; and

         (iv)     no provision of this Guarantee Agreement shall require the
                  Guarantee Trustee to expend or risk its own funds or otherwise
                  incur personal financial liability in the performance of any
                  of its duties or in the exercise of any of its rights or
                  powers,

                  if the Guarantee Trustee shall have reasonable grounds for
                  believing that the repayment of such funds or liability is not
                  reasonably assured to it under the terms of this Guarantee
                  Agreement or adequate indemnity against such risk or liability
                  is not reasonably assured to it.

SECTION 3.2. CERTAIN RIGHTS OF GUARANTEE TRUSTEE.

       (a) Subject to the provisions of Section 3.1:

         (i)      The Guarantee Trustee may rely and shall be fully protected in

         (iii)    Whenever, in the administration of this Guarantee Agreement,
                  the Guarantee Trustee shall deem it desirable that a matter be
                  proved or established before taking, suffering or omitting to
                  take any action hereunder, the Guarantee Trustee (unless other
                  evidence is herein specifically prescribed) may, in the
                  absence of bad faith on its part, request and rely upon an
                  Officers' Certificate which, upon receipt of such request from
                  the Guarantee Trustee, shall be promptly delivered by the
                  Guarantor.

         (iv)     The Guarantee Trustee may consult with legal counsel, and the
                  written advice or opinion of such legal counsel with respect

                  protection in respect of any action taken, suffered or omitted
                  to be taken by it hereunder in good faith and in accordance
                  with such advice or opinion. Such legal counsel may be legal
                  counsel to the Guarantor or any of its Affiliates and may be
                  one of its employees. The Guarantee Trustee shall have the
                  right at any time to seek instructions concerning the

                  any of the rights or powers vested in it by this Guarantee
                  Agreement at the request or direction of any Holder, unless
                  such Holder shall have provided to the Guarantee Trustee such
                  adequate security and indemnity as would satisfy a reasonable
                  person in the position of the Guarantee Trustee, against the
                  costs, expenses (including attorneys' fees and expenses) and
                  liabilities that might be incurred by it in complying with
                  such request or direction, including such reasonable advances
                  as

                                       -8-

<PAGE>   13



                  may be requested by the Guarantee Trustee; provided that,
                  nothing contained in this Section 3.2(a)(v) shall be taken to
                  relieve the Guarantee Trustee, upon the occurrence of an Event
                  of Default, of its obligation to exercise the rights and
                  powers vested in it by this Guarantee Agreement.

         (vi)     The Guarantee Trustee shall not be bound to make any
                  investigation into the facts or matters stated in any

                  report, notice, request, direction, consent, order, bond,
                  debenture, note, other evidence of indebtedness or other paper
                  or document, but the Guarantee Trustee, in its discretion, may
                  make such further inquiry or investigation into such facts or
                  matters as it may see fit.

         (vii)    The Guarantee Trustee may execute any of the trusts or powers
                  hereunder or perform any duties hereunder either directly or
                  by or through its agents or attorneys, and the Guarantee
                  Trustee shall not be responsible for any misconduct or
                  negligence on the part of any such agent or attorney appointed
                  with due care by it hereunder.

         (viii)   Any action taken by the Guarantee Trustee or its agents
                  hereunder shall bind the Holders, and the signature of the
                  Guarantee Trustee or its agents alone shall be sufficient and
                  effective to perform any such action. No third party shall be
                  required to inquire as to the authority of the Guarantee
                  Trustee to so act or as to its compliance with any of the
                  terms and provisions of this Guarantee Agreement, both of
                  which shall be conclusively evidenced by the Guarantee
                  Trustee's or its agent's taking such action.

         (ix)     Whenever in the administration of this Guarantee Agreement the
                  Guarantee Trustee shall deem it desirable to receive
                  instructions with respect to enforcing any remedy or right or
                  taking any other action hereunder, the Guarantee Trustee (A)
                  may request instructions from the Holders of a Majority in
                  liquidation preference of the Preferred Securities, (B) may
                  refrain from enforcing such remedy or right or taking such
                  other action until such instructions are received, and (C)
                  shall be protected in acting in accordance with such
                  instructions.

       (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

                  Trustee has been appointed and has accepted such appointment
                  by instrument in writing executed by such Successor Guarantee
                  Trustee and delivered to the Guarantor and the resigning
                  Guarantee Trustee.

         (iv)     If no Successor Guarantee Trustee shall have been appointed

                  instrument of resignation, the resigning Guarantee Trustee may
                  petition any court of competent jurisdiction for appointment
                  of a Successor Guarantee Trustee. Such court may thereupon,
                  after prescribing such notice, if any, as it may deem proper,
                  appoint a Successor Guarantee Trustee.

                              ARTICLE V. GUARANTEE

SECTION 5.1. GUARANTEE.

       The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim which the Issuer may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer to pay such amounts to the Holders.

SECTION 5.2. WAIVER OF NOTICE AND DEMAND.

       The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the
Guarantee Trustee, Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

SECTION 5.3. OBLIGATIONS NOT AFFECTED.

       The obligations, covenants, agreements and duties of the Guarantor under
this Guarantee Agreement shall in no way be affected or impaired by reason of
the happening from time to time of any of the following:

       (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

                                      -11-

<PAGE>   16




       (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sums payable that results from the extension of any interest payment period on
the Debentures as so provided in the Indenture);

       (c) any failure, omission, delay or lack of diligence on the part of the
Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer granting indulgence or extension of any
kind;

       (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

       (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

       (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

       (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

       There shall be no obligation of the Holders to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4. RIGHTS OF HOLDERS.

       The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of this Guarantee Agreement or exercising any
trust or power conferred upon the Guarantee Trustee under this Guarantee
Agreement; and (iv) if the Guarantee Trustee fails to enforce this Guarantee
Agreement after a Holder has made a written request for the Guarantee Trustee to
do so, any Holder may, to the extent permitted by law, institute a legal
proceeding directly against the Guarantor to enforce its rights under this
Guarantee Agreement, without first instituting a legal proceeding against the
Guarantee Trustee, the Issuer or any other Person. Notwithstanding the
foregoing, if the Guarantor has failed to make a Guarantee Payment, a

                                      -12-

<PAGE>   17



Holder may directly institute a proceeding against the Guarantor for enforcement
of this Guarantee Agreement for such payment. The Guarantor waives any right or
remedy to require that any action on this Guarantee Agreement be brought first
against the Issuer or any other Person or entity before proceeding directly
against the Guarantor.

SECTION 5.5. GUARANTEE OF PAYMENT

       This Guarantee Agreement creates a guarantee of payment and not of
collection.

SECTION 5.6. SUBROGATION.

       The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

SECTION 5.7. INDEPENDENT OBLIGATIONS.

       The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Preferred Securities and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

                     ARTICLE VI. COVENANTS AND SUBORDINATION

SECTION 6.1. SUBORDINATION.

       This Guarantee Agreement will constitute an unsecured obligation of the
Guarantor and will rank subordinate and junior in right of payment to all Senior
Debt of the Guarantor.

SECTION 6.2. PARI PASSU GUARANTEES.

       This Guarantee Agreement shall rank pari passu with any similar Guarantee
Agreements issued by the Guarantor on behalf of the holders of Preferred
Securities issued by Lincoln National Capital I, Lincoln National Capital II and
Lincoln National Capital III.

effect upon (i) full payment of the Redemption Price of all Preferred
Securities, (ii) the distribution of Debentures to the Holders in exchange for
all of the Preferred Securities or (iii) full payment of the amounts payable in
accordance with the Trust Agreement upon liquidation of the Issuer.
Notwithstanding the foregoing, this Guarantee Agreement will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
must restore payment of any sums paid with respect to Preferred Securities or
this Guarantee Agreement.


                           ARTICLE VIII. MISCELLANEOUS

Securities then outstanding. Except in connection with a consolidation, merger
or sale involving the Guarantor that is permitted under Article Eight of the

Guarantor's obligations hereunder, the Guarantor shall not assign its
obligations hereunder.

Holders will be required), this Guarantee Agreement may only be amended with the
prior approval of the Holders of not less than a Majority in liquidation
preference of the Preferred Securities. The provisions of Article VI of the
