         Section 4.04. Securities Intermediary's Jurisdiction. The Collateral
Account, and the rights and obligations of the Securities Intermediary, the
Collateral Agent, the Purchase Contract Agent and the Holders with respect
thereto, shall be governed by the laws of the State of New York. Regardless of
any provision in any other agreement, for purposes of the UCC, New York shall be

lien, encumbrance or adverse claim (including any writ, garnishment, judgment,
purchase contract of attachment, execution or similar process) against the
Collateral Account or in any financial asset carried therein, the Securities

duties hereunder.

         Section 4.09. No Other Agreements. The Securities Intermediary has not
entered into, and prior to the termination of the Pledge will not enter into,
any agreement with any other Person relating to the Collateral Account or any
financial assets credited thereto, including, without limitation, any agreement

         Section 4.10. Powers Coupled With An Interest. The rights and powers
granted in this Article 4 to the Collateral Agent have been granted in order to
perfect its security interests in the Collateral Account, are powers coupled
with an interest and will be affected neither by the bankruptcy of the Purchase
Contract Agent or any Holder nor by the lapse of time. The obligations of the
Securities Intermediary under this Article 4 shall continue in effect until the
termination of the Pledge.

         Section 4.11. Waiver Of Lien; Waiver Of Set-off. The Securities
Intermediary waives any security interest, lien or right to make deductions or
setoffs that it may now have or hereafter acquire in or with respect to the

entitlement in respect thereof. Neither the financial assets credited to the

         requesting that the Collateral Agent release from the Pledge the
         Pledged Treasury Securities related to such Treasury Units; and

                  (ii)     delivering the related Treasury Units to the Purchase

such an event, the Holder shall Transfer the required Applicable Ownership
Interests in the Treasury Portfolio to the Securities Intermediary, for credit

of the Pledge created hereby; provided, however, if any Holder shall be entitled
to receive less than $1,000 with respect to its interest in the Applicable
Ownership Interests (as specified in clause (i) of the definition of such term)
in the Treasury Portfolio, the Purchase Contract Agent shall dispose of such
interest for cash and deliver to such Holder cash in lieu of delivering the
Applicable Ownership Interests (as specified in clause (i) of the definition of
such term) in the Treasury Portfolio.

         (b)      If such Termination Event shall result from the Company's

Pledged Senior Notes, Pledged Applicable Ownership Interests, Pledged Treasury
Securities and payments by Holders (or the Permitted Investments of such
payments) pursuant to Section 5.05 hereof and Proceeds of any of the foregoing,
as the case may be, as provided by this Section 5.04, the Purchase Contract

                  (i)      use its best efforts to obtain an opinion of a
         nationally recognized law firm to the effect that, notwithstanding 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 5.04, and shall deliver or cause
         to be delivered such opinion to the Collateral Agent within ten days
         after the occurrence of such Termination Event, and if (A) the Purchase
         Contract Agent shall be unable to obtain such opinion within ten days
         after the occurrence of such Termination Event or (B) the Collateral
         Agent shall continue, after delivery of such opinion, to refuse to
         effectuate the release and Transfer of all Pledged Senior Notes,
         Pledged Applicable Ownership Interests, Pledged Treasury Securities and
         the payments by Holders (or the Permitted Investments of such payments)
         pursuant to Section 5.05 hereof and Proceeds of any of the foregoing,
         as the case may be, as provided in this Section 5.04, then the Purchase
         Contract Agent shall within fifteen days after the occurrence of such
         Termination Event commence an action or proceeding in the court having
         jurisdiction of the Company's case under the Bankruptcy Code seeking an

         Interests, Pledged Treasury Securities and the payments by Holders (or
         the Permitted Investments of such payments) pursuant to Section 5.05
         hereof and Proceeds of any of the foregoing, or as the case may be, as
         provided by this Section 5.04; or

                  (ii)     commence an action or proceeding like that described
         in clause 5.04(b)(i) hereof within ten days after the occurrence of
         such Termination Event.

                  (ii)     instruct the Securities Intermediary to release from
         the Pledge such Holder's related Pledged Senior Notes, Pledged

         Contract Agent for distribution to such Holder, in each case free and
         clear of the Pledge created hereby.

         The Company shall instruct the Collateral Agent in writing as to the
type of Permitted Investments in which any such Cash shall be invested;
provided, however, that if the Company fails to deliver such written
instructions by 10:30 a.m. (New York City time) on the day such Cash is received
by the Collateral Agent or to be reinvested by the Securities Intermediary, the
Collateral Agent shall instruct the Securities Intermediary to invest such Cash
in the Permitted Investments described in clause (6) of the definition of
Permitted Investments. In no event shall the Collateral Agent or Securities
Intermediary be liable for the selection of Permitted Investments or for
investment losses incurred thereon. The Collateral Agent and Securities
Intermediary shall have no liability in respect of losses incurred as a result
of the failure of the Company to provide timely written investment direction.

         Upon receipt of the proceeds upon the maturity of the Permitted
Investments on the Purchase Contract Settlement Date, the Collateral Agent shall
instruct the Securities Intermediary to (A) pay the portion of such proceeds and
deliver any certified or cashier's checks received, in an aggregate amount equal
to the Settlement Price, to the Company on the Purchase Contract Settlement

the Purchase Contract Agreement, such Holder shall be deemed to have consented
to the disposition of such Holder's Pledged Senior Notes in accordance with
paragraph 5.02(c)(iii) of the Purchase Contract Agreement.

         (c)      If a Holder of a Treasury Unit or a Holder of a Corporate Unit

deemed to have elected to pay the Settlement Price in accordance with paragraph
5.02(f)(iii) of the Purchase Contract Agreement.

         (d)      As soon as practicable after 11:00 a.m. (New York City time)

Corporate Units, (ii) the amount of Cash that it has received with respect to
the Cash Settlement of Treasury Units and (iii) the amount of Pledged Senior
Notes to be remarketed in the Final Remarketing pursuant to Section 5.02(c)(iii)
of the Purchase Contract Agreement.

         Section 5.06. Early Settlement And Cash Merger Early Settlement. Upon
receipt by the Collateral Agent of a notice from the Purchase Contract Agent
that a Holder of Units has elected to effect either (i) Early Settlement of its
obligations under the Purchase Contracts represented by such Units in accordance
with the terms of the Purchase Contracts and Section 5.07 of the Purchase
Contract Agreement or (ii) Cash Merger Early Settlement of its obligations under
the Purchase Contracts represented by such Units in accordance with the terms of
the Purchase Contracts and Section 5.04(b)(2) of the Purchase Contract Agreement
(which notice shall set forth the number of such Purchase Contracts as to which
such Holder has elected to effect Early Settlement or Cash Merger Early
Settlement), and that the Purchase Contract Agent has received from such Holder,
and paid to the Company as confirmed in writing by the Company, the related
Settlement Price pursuant to the terms of the Purchase Contracts and the
Purchase

                                       16

Contract Agreement and that all conditions to such Early Settlement or Cash
Merger Early Settlement, as the case may be, have been satisfied, then the
Collateral Agent shall release from the Pledge, (1) Pledged Senior Notes or the
Pledged Applicable Ownership Interests in the case of a Holder of Corporate
Units or (2) Pledged Treasury Securities, in the case of a Holder of Treasury
Units, in each case with a Value equal to the product of (x) the Stated Amount
times (y) the number of Purchase Contracts as to which such Holder has elected
to effect Early Settlement or Cash Merger Early Settlement, and shall instruct
the Securities Intermediary to Transfer all such Pledged Applicable Ownership
Interests or Pledged Senior Notes or Pledged Treasury Securities, as the case
may be, to the Purchase Contract Agent for distribution to such Holder, in each
case free and clear of the Pledge created hereby. A holder of Treasury Units may
settle early only in integral multiples of 40 Treasury Units, and a Holder of
Corporate Units, if the Treasury Portfolio has replaced the Senior Notes
represented by such Corporate Units, may settle early only in integral multiples
of 4,000 Corporate Units.

         Section 5.07. Application Of Proceeds In Settlement Of Purchase
Contracts. (a) If a Holder of Corporate Units (if the Treasury Portfolio has not
replaced the Senior Notes represented by such Corporate Units) has not elected
to make an effective Cash Settlement by notifying the Purchase Contract Agent in
the manner provided for in Section 5.02(c)(i) of the Purchase Contract Agreement
or does notify the Purchase Contract Agent as provided in paragraph 5.02(c)(i)
of the Purchase Contract Agreement of its intention to pay the Settlement Price
in cash, but fails to make such payment as required by paragraph 5.02(c)(ii) of
the Purchase Contract Agreement, such Holder shall be deemed to have elected to
pay for the shares of Common Stock to be issued under such Purchase Contracts
from the Proceeds of the Final Remarketing of the related Pledged Senior Notes.
In the event of a Successful Final Remarketing, the Collateral Agent shall
instruct the Securities Intermediary to Transfer the related Pledged Senior
Notes to the Remarketing Agent upon confirmation of deposit by the Remarketing
Agent of the Proceeds of such Final Remarketing (less, to the extent permitted
by the Remarketing Agreement, the Remarketing Fee) in the Collateral Account.
The Collateral Agent shall instruct the Securities Intermediary to invest the
Proceeds of the Final Remarketing in Permitted Investments set forth in clause
(6) of the definition of Permitted Investments. On the Purchase Contract
Settlement Date, the Collateral Agent shall, in consultation with the Purchase
Contract Agent, instruct the Securities Intermediary to remit a portion of the
Proceeds from such Final Remarketing equal to the aggregate principal amount of
such Pledged Senior Notes to the Company to satisfy in full such Holder's
obligations to pay the Settlement Price to purchase the shares of Common Stock
under the related Purchase Contracts and to remit the balance of the Proceeds
from the Final Remarketing, if any, to the Purchase Contract Agent for
distribution to such Holder.

                                       17

<PAGE>

         If the Remarketing Agent advises the Collateral Agent in writing that
there has been a Failed Final Remarketing, the Collateral Agent, for the benefit
of the Company shall, at the written direction of the Company, exercise the
Company's rights as a secured party with respect to the Pledged Notes in
accordance with applicable law or deliver the Pledged Notes to the Company to
retain to the extent permitted by applicable law. Following such action, the
Holder's obligations to pay the Purchase Price for the shares of Common Stock
will be deemed to be satisfied in full.

         (b)      If a Holder of a Treasury Unit or a Holder of a Corporate Unit
(if the Treasury Portfolio has replaced the Senior Notes represented by such
Corporate Unit) has not elected to make an effective Cash Settlement by
notifying the Purchase Contract Agent in the manner provided for in Section
5.02(f)(i) of the Purchase Contract Agreement, or has given such notice but
failed to make such payment in the manner required by Section 5.02(f)(ii) of the
Purchase Contract Agreement, such Holder shall be deemed to have elected to pay
for the shares of Common Stock to be issued under such Purchase Contracts from
the Proceeds of the related Pledged Treasury Securities or Pledged Applicable
Ownership Interests, as the case may be. Promptly, after 11:00 a.m. (New York
City time) on the Business Day immediately prior to the Purchase Contract
Settlement Date, the Collateral Agent shall instruct the Securities Intermediary
to invest the Cash Proceeds of the maturing Pledged Treasury Securities or
Pledged Applicable Ownership Interests, as the case may be, in Permitted
Investments set forth in clause (6) of the definition of Permitted Investments,
unless prior to 10:30 a.m. (New York City time) on such date, the Company shall
otherwise instruct the Collateral Agent in writing as to the type of Permitted
Investments in which any such Cash Proceeds shall be invested. In no event shall
the Collateral Agent be liable for the selection of Permitted Investments or for
investment losses incurred thereon. The Collateral Agent shall have no liability
in respect of losses incurred as a result of the failure of the Company to
provide timely written investment direction. Without receiving any instruction
from any such Holder, the Collateral Agent shall instruct the Securities
Intermediary to remit the Proceeds of the related Pledged Treasury Securities or
Pledged Applicable Ownership Interests, as the case may be, to the Company in
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 Pledged Applicable Ownership Interests, as the case may be, and
the investment earnings from the investment in Permitted Investments exceeds the
aggregate Settlement Price of the Purchase Contracts being settled thereby, the
Collateral Agent shall instruct the Securities Intermediary to transfer such
excess, when received, to the Purchase Contract Agent for distribution to such
Holder.

         (c)      Prior to 5:00 p.m. (New York City time) on the fifth Business
Day immediately preceding the applicable Remarketing Date, but no earlier than
the Payment Date immediately preceding such date, Holders of Separate Senior
Notes may elect to have their Separate Senior Notes remarketed under the
Remarketing

                                       18

<PAGE>

Agreement, by delivering their Separate Senior Notes along with a notice of such
election, substantially in the form of Exhibit F hereto, to the Custodial Agent.
After such time, such election shall become an irrevocable election to have such
Separate Senior Notes remarketed in such Remarketing and, if such Remarketing
fails, in any subsequent Remarketing. The Custodial Agent shall hold Separate
Senior Notes in an account separate from the Collateral Account in which the
Pledged Securities shall be held. Holders of Separate Senior Notes electing to
have their Separate Senior Notes remarketed will also have the right to withdraw
that election by written notice to the Custodial Agent, substantially in the
form of Exhibit G hereto, prior to 5:00 p.m. (New York City time) on the fifth
Business Day immediately preceding the applicable Remarketing Date, upon which
notice the Custodial Agent shall return such Separate Senior Notes to such
Holder.

         By 11:00 a.m. (New York City time) on the Business Day immediately
preceding the applicable Remarketing Date, the Custodial Agent shall notify the
Remarketing Agent of the aggregate principal amount of the Separate Senior Notes
to be remarketed and deliver to the Remarketing Agent for remarketing all
Separate Senior Notes delivered to the Custodial Agent pursuant to this Section
5.07(c) and not validly withdrawn prior to such date. In the event of a
Successful Remarketing, after deducting the Remarketing Fee (to the extent
permitted under the terms of the Remarketing Agreement), the Remarketing Agent
will remit to the Custodial Agent the remaining portion of the proceeds of such
Remarketing for payment to the Holders of the remarketed Separate Senior Notes,
in accordance with their respective interests. In the event of a Failed
Remarketing, the Remarketing Agent will promptly return such Separate Senior
Notes to the Custodial Agent, and, in the event of a Failed Final Remarketing,
the Custodial Agent shall deliver such Separate Senior Notes to the appropriate
Holders.

         Section 5.08. Special Event Redemption. If the Collateral Agent
receives written notice that a Special Event Redemption has occurred while
Senior Notes are still credited to the Collateral Account, the Collateral Agent
shall cause the Redemption Amount to be deposited in the Collateral Account and
shall instruct the Securities Intermediary to apply the Redemption Amount to
purchase the Treasury Portfolio, and to credit the Applicable Ownership
Interests (as specified in clause (i) of the definition of such term) in the
Treasury Portfolio to the Collateral Account and transfer the Applicable
Ownership Interests (as specified in clause (ii)(y) of the definition of such
term) in the Treasury Portfolio to the Purchase Contract Agent for distribution
to the Holders of the Corporate Units. Upon credit to the Collateral Account of
the Applicable Ownership Interests (as specified in clause (i) of the definition
of such term) in the Treasury Portfolio having a Value equal to the aggregate
principal amount of the Pledged Senior Notes, the Collateral Agent shall cause
the Securities Intermediary to release the Pledged Senior Notes from the
Collateral Account and promptly transfer the Pledged Senior Notes to the
Company.

                      VOTING RIGHTS -- PLEDGED SENIOR NOTES

         Section 6.01. Voting Rights. Subject to the terms of Section 4.02 of
the Purchase Contract Agreement, the Purchase Contract Agent may exercise, or
refrain from exercising, any and all voting and other consensual rights
pertaining to the Pledged Senior Notes 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 shall not refrain from exercising such right, as the case
may be, if, in the judgment of the Purchase Contract Agent, such action would
impair or otherwise have a material adverse effect on the value of all or any of
the Pledged Senior Notes; and provided, further, that the Purchase Contract
Agent shall give the Company and the Collateral Agent at least five Business
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 Senior Notes,
including notice of any meeting at which holders of the Senior Notes are
entitled to vote or solicitation of consents, waivers or proxies of holders of
the Senior Notes, 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 Senior Notes (in
form and substance satisfactory to the Collateral Agent) as are prepared by the
Company and delivered to the Purchase Contract Agent with respect to the Pledged
Senior Notes.

                               RIGHTS AND REMEDIES

         Section 7.01. Rights And Remedies Of The Collateral Agent. (a) In
addition to the rights and remedies specified in Section 5.07 hereof or
otherwise available at law or in equity, after an event of default (as specified
in Section 7.01(b) below) hereunder, the Collateral Agent shall have all of the
rights and remedies with respect to the Collateral of a secured party under the
UCC (whether or not the UCC 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.
Without limiting the generality of the foregoing, such remedies may include, to
the extent permitted by applicable law, (1) retention of the Pledged Senior
Notes, Pledged Treasury Securities or the applicable Pledged Applicable
Ownership Interests in full satisfaction of the Holders' obligations under the
Purchase Contracts and the Purchase Contract Agreement or (2) sale of the
Pledged Senior Notes, Pledged

                                       20

<PAGE>

Treasury Securities or the applicable Pledged Applicable Ownership Interests 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 applicable Pledged
Applicable Ownership Interests, or on account of principal payments of any
Pledged Treasury Securities as provided in Article 3 hereof, in satisfaction of
the Obligations of the Holder of the Units represented by such applicable
Pledged Applicable Ownership Interests or such Pledged Treasury Securities, as
applicable, 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 Pledged Applicable Ownership Interests, as applicable, any and all of the
rights and remedies available to a secured party under the UCC 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 principal
amount of the Pledged Senior Notes, (ii) the principal amount of the Pledged
Treasury Securities and (iii) the principal amount of the Pledged Applicable
Ownership Interests, subject, in each case, to the provisions of Article 3
hereof, and as otherwise granted herein.

         (d)      The Purchase Contract Agent and each Holder of Units agrees
that, from time to time, upon the written request of the Collateral Agent or the
Purchase Contract Agent, such Holder shall execute and deliver such further
documents and do such other acts and things as the Collateral Agent may
reasonably request or as may be necessary or advisable 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
grossly negligent acts, its own grossly negligent failure to act or its own
willful misconduct.

         Section 7.02. Special Event Redemption. Upon the occurrence of a
Special Event Redemption while Senior Notes are still credited to the Collateral
Account, the Collateral Agent is hereby authorized to present the Pledged Senior
Notes for payment as may be required by their respective terms and to direct the
Indenture Trustee to remit the Redemption Price to the Securities Intermediary
for credit to the Collateral Account on or prior to 12:30 p.m., New York City
time on such Special Event Redemption Date, by federal funds check or wire
transfer of immediately available funds. Upon receipt of such funds, the Pledged
Senior Notes shall be released from the Collateral Account. Upon the crediting
of such funds to the Collateral Account, the Collateral Agent, at the written
direction of

                                       21

<PAGE>

the Company, shall instruct the Securities Intermediary to (a) apply an amount
equal to the Redemption Amount of such funds to purchase the Treasury Portfolio
from the Quotation Agent, (b) credit to the Collateral Account the Applicable
Ownership Interests specified in clause (i) of the definition of such term and
(c) promptly remit the remaining portion of such funds, if any, to the Purchase
Contract Agent for payment to the Holders of Corporate Units, in accordance with
their respective interests.

         Section 7.03. Successful Remarketing. In the event of a Successful
Remarketing prior to the Final Remarketing Date, the Collateral Agent shall, at
the direction of the Company, instruct the Securities Intermediary to (i)
Transfer the Pledged Senior Notes to the Remarketing Agent upon confirmation of
deposit by the Remarketing Agent of the Proceeds of such Successful Remarketing
(after deducting any Remarketing Fee to the extent permitted under the terms of
the Remarketing Agreement) in the Collateral Account, (ii) apply an amount equal
to the Treasury Portfolio Purchase Price to purchase from the Quotation Agent
the Treasury Portfolio, (iii) credit the Applicable Ownership Interests
specified in clause (i) of the definition of such term to the Collateral
Account, and (iv) promptly remit the remaining portion of such Proceeds to the
Purchase Contract Agent for payment to the Holders of Corporate Units, in
accordance with their respective interests. With respect to Separate Senior
Notes, any Proceeds of such Remarketing (after deducting any Remarketing Fee to
the extent permitted under the terms of the Remarketing Agreement) attributable
to the Separate Senior Notes will be remitted to the Custodial Agent for payment
to the holders of Separate Senior Notes. The Pledged Applicable Ownership
Interests thus credited to the Collateral Account will secure the obligation of
all Holders of Corporate Units to purchase Common Stock of the Company under the
Purchase Contracts represented by such Corporate Units, in substitution for the
Pledged Senior Notes, which shall be released from the Collateral Account. In
the event of a Failed Final Remarketing, the Pledged Senior Notes shall remain
credited to the Collateral Account.

         Section 7.04. Substitutions. Whenever a Holder has the right to
substitute Treasury Securities, Senior Notes or security entitlements for any of
them or the appropriate Applicable Ownership Interests (as defined in clause (i)
of the definition of such term) in the Treasury Portfolio, as the case may be,
for financial assets held in the Collateral Account, such substitution shall not
constitute a novation of the security interest created hereby.

                    REPRESENTATIONS AND WARRANTIES; COVENANTS

         Section 8.01. Representations And Warranties. Each Holder from time to
time, acting through the Purchase Contract Agent as attorney-in-fact (it being
understood that the Purchase Contract Agent shall not be liable for any

                                       22

<PAGE>

representation or warranty made by or on behalf of a Holder), hereby represents
and purchase contracts to the Collateral Agent (with respect to such Holder's
interest in the Collateral), 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 for credit to the
Collateral Account, 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 Article 2 hereof;

         (c)      upon the Transfer of the Collateral to the Collateral Agent
for credit 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 securities
intermediary or other entity not within the control of the Holder involved in
the Transfer of the Collateral, including the Collateral Agent and the
Securities Intermediary, 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 Article 4 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 Article 2 hereof or violate any provision of any existing law
or regulation applicable to it or of any mortgage, charge, pledge, indenture,
contract or undertaking to which it is a party or which is binding on it or any
of its assets.

         Section 8.02. 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

                                       23

for the beneficial interest therein, subject to the Pledge hereunder,
transferred in connection with the Transfer of any Units.

                                  INTERMEDIARY

         It is hereby agreed as follows:

         Section 9.01. Appointment, Powers And Immunities. The Collateral Agent,
the Custodial Agent or Securities Intermediary shall act as agent for the
Company hereunder with such powers as are specifically vested in the Collateral
Agent, the Custodial Agent or Securities Intermediary, as the case may be, by
the terms of this Agreement. The Collateral Agent, the Custodial Agent and
Securities Intermediary shall:

         (a)      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 the Collateral Agent, the Custodial Agent
and Securities Intermediary, nor shall the Collateral Agent, the Custodial Agent
and Securities Intermediary be bound by the provisions of any agreement by any
party hereto beyond the specific terms hereof;

         (b)      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 Certificates 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 Custodial Agent or Securities Intermediary, as the case
may be), the Purchase Contracts, the Senior Notes, any Collateral 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 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)      not be required to initiate or conduct any litigation or
collection proceedings hereunder (except pursuant to directions furnished under
Section 9.02 hereof, subject to Section 9.08 hereof);

         (d)      not be responsible for any action taken or omitted to be taken

         (e)      not be required to advise any party as to selling or
retaining, or taking or refraining from taking any action with respect to, any
securities or other property deposited hereunder.

Subject to the foregoing, during the term of this Agreement, the Collateral
Agent, the Custodial Agent and the Securities Intermediary shall take all
reasonable action in connection with the safekeeping and preservation of the
Collateral hereunder as determined by industry standards.

         No provision of this Agreement shall require the Collateral Agent,
Custodial Agent or 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, Custodial Agent or Securities
Intermediary be liable for any amount in excess of the Value of the Collateral.

         None of the Collateral Agent, the Custodial Agent or the Securities
Intermediary has any obligation or responsibility to file UCC financing
statements.

         Section 9.02. Instructions Of The Company. The Company shall have the
right, by one or more written instruments executed and delivered to the
Collateral Agent, 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,
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 or involve the Collateral
Agent in personal liability and (ii) the Collateral Agent shall be indemnified
to its satisfaction as provided herein. Nothing contained in this Section 9.02
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 9.03. Reliance By Collateral Agent And Securities Intermediary.
Each of the Securities Intermediary, the Custodial Agent and the Collateral
Agent shall be entitled to rely conclusively upon any certification, order,

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 consult with and
conclusively rely upon advice, opinions 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 9.04. Certain Rights. (a) Whenever in the administration of the
provisions of this Agreement the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering any action to be taken
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of gross negligence or bad faith on
the part of the Collateral Agent, the Custodial Agent or the Securities
Intermediary, be deemed to be conclusively proved and established by a
certificate signed by one of the Company's officers, and delivered to the
Collateral Agent, the Custodial Agent or the Securities Intermediary and such
certificate, in the absence of gross negligence or bad faith on the part of the
Collateral Agent, the Custodial Agent or the Securities Intermediary, shall be
full warrant to the Collateral Agent, the Custodial Agent or the Securities
Intermediary for any action taken, suffered or omitted by it under the
provisions of this Agreement upon the faith thereof.

         (b)      The Collateral Agent, the Custodial Agent or the Securities
Intermediary 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, entitlement order, approval or other paper or
document.

         Section 9.05. Merger, Conversation, Consolidation Or Succession To
Business. Any corporation into which the Collateral Agent, the Custodial Agent
or the Securities Intermediary may be merged or converted or with which it may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall be a party, or any corporation succeeding to the
business of the Collateral Agent, the Custodial Agent or the Securities
Intermediary shall be the successor of the Collateral Agent, the Custodial Agent
or the Securities Intermediary hereunder without the execution or filing of any
paper with any party hereto or any further act on the part of any of the parties
hereto except where an instrument of transfer or assignment is required by law
to effect such succession, anything herein to the contrary notwithstanding.

         Section 9.06. 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 other Person
interested herein and any Holder of Units (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, the Custodial Agent, the Securities Intermediary and their

Intermediary acted with gross negligence or engaged in willful misconduct or bad

option, each of the Collateral Agent and the Custodial Agent shall be entitled,
after prompt notice to the Company and the Purchase Contract Agent, to refuse to
comply with any and all claims, demands or instructions with respect to such
property or funds so long as such dispute or conflict shall continue, and the

Collateral Agent or the Custodial Agent; or

         (b)      the Collateral Agent or the Custodial Agent shall have
received security or an indemnity satisfactory to it sufficient to save it
harmless from and against any and all loss, liability or reasonable
out-of-pocket expense which it may incur by reason of its acting.

The Collateral Agent, the Custodial Agent and the Securities Intermediary may in
addition elect to commence an interpleader action or seek other judicial relief
or orders as the Collateral Agent, the Custodial Agent or the Securities
Intermediary may deem necessary. Notwithstanding anything contained herein to
the contrary, none of the Collateral Agent, the Custodial Agent or the
Securities Intermediary 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.

Collateral Agent, Custodial Agent or Securities Intermediary as provided below:

                                       28

<PAGE>

                  (i)      the Collateral Agent, the Custodial Agent and the
         Securities Intermediary 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 Units;

                  (ii)     the Collateral Agent, the Custodial Agent and the
         Securities Intermediary may be removed at any time by the Company; and

                  (iii)    if the Collateral Agent, the Custodial Agent or the
         Securities Intermediary 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, the Custodial Agent and the Securities Intermediary
         may be removed by the Purchase Contract Agent, acting at the direction
         of the Holders of Units.

The Purchase Contract Agent shall promptly notify the Company of any removal of
the Collateral Agent, the Custodial Agent or the Securities Intermediary
pursuant to clause (iii) of this Section 9.10. Upon any such resignation or
removal, the Company shall have the right to appoint a successor Collateral
Agent, Custodial Agent or Securities Intermediary, as the case may be, which
shall not be an Affiliate of the Purchase Contract Agent. If no successor
Collateral Agent, Custodial Agent or Securities Intermediary shall have been so
appointed and shall have accepted such appointment within 30 days after the
retiring Collateral Agent's, Custodial Agent's or Securities Intermediary's
giving of notice of resignation or the Company's or the Purchase Contract
Agent's giving notice of such removal, then the retiring or removed Collateral
Agent, Custodial Agent or Securities Intermediary may petition any court of
competent jurisdiction, at the expense of the Company, for the appointment of a
successor Collateral Agent, Custodial Agent or Securities Intermediary. The
Collateral Agent, the Custodial Agent and the Securities Intermediary shall each
be a bank or a national banking association which has an office (or an agency
office) in New York City with a combined capital and surplus of at least
$50,000,000. Upon the acceptance of any appointment as Collateral Agent,
Custodial Agent or Securities Intermediary hereunder by a successor Collateral
Agent, Custodial Agent or Securities Intermediary, as the case may be, such
successor Collateral Agent, Custodial Agent or Securities Intermediary, as the
case may be, shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Collateral Agent, Custodial Agent
or Securities Intermediary, as the case may be, and the retiring Collateral
Agent, Custodial Agent or Securities Intermediary, as the case may be, shall
take all appropriate action, subject to payment of any amounts then due and
payable to it hereunder, to transfer any money and property held by it hereunder
(including the Collateral) to such successor. The retiring Collateral Agent,
Custodial Agent or Securities Intermediary shall, upon such succession, be
discharged from its duties and obligations as Collateral Agent, Custodial Agent
or Securities Intermediary hereunder. After any retiring Collateral Agent's,
Custodial Agent's or Securities Intermediary's resignation

                                       29

<PAGE>

hereunder as Collateral Agent, Custodial Agent or Securities Intermediary, the
provisions of this Article 9 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, Custodial Agent or Securities Intermediary. Any resignation or
removal of the Collateral Agent, Custodial Agent or Securities Intermediary
hereunder, at a time when such Person is acting as the Collateral Agent,
Custodial Agent or Securities Intermediary, shall be deemed for all purposes of
this Agreement as the simultaneous resignation or removal of the Collateral
Agent, Securities Intermediary or Custodial Agent, as the case may be.

         Section 9.11. 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 9.11
shall be subject to prior written consent of the Company, which consent shall
not be unreasonably withheld.

         Section 9.12. Survival. The provisions of this Article 9 shall survive
termination of this Agreement and the resignation or removal of the Collateral
Agent, the Custodial Agent or the Securities Intermediary.

         Section 9.13. Exculpation. Anything contained in this Agreement to the
contrary notwithstanding, in no event shall the Collateral Agent, the Custodial
Agent or the Securities Intermediary or their officers, directors, 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, but
not limited to, 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 and regardless of the form of action.

                                   ARTICLE 10
                                    AMENDMENT

         Section 10.01. Amendment Without Consent Of Holders. Without the
consent of any Holders, the Company, when authorized by a Board Resolution, 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
Custodial Agent, the Securities Intermediary and the Purchase Contract Agent,
to:

         (a)      evidence the succession of another Person to the Company and
the assumption by any such successor of the covenants of the Company;

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

         (c)      add to the covenants of the Company for the benefit of the
Holders, or surrender any right or power herein conferred upon the Company,
provided that such covenants or such surrender do not adversely affect the
validity, perfection or priority of the Pledge created hereunder; or

         (d)      cure any ambiguity (or formal defect), correct or supplement
any provisions herein which may be inconsistent with any other such provisions
herein, or make any other provisions with respect to such matters or questions
arising under this Agreement, provided that such action shall not adversely
affect the interests of the Holders in any material respect.

         Section 10.02. Amendment With Consent Of Holders. With the consent of
the Holders of not less than a majority of the Purchase Contracts at the time
outstanding, including without limitation the consent of the Holders obtained in
connection with a tender or an exchange offer, by Act of such Holders delivered
to the Company, the Purchase Contract Agent, the Custodial Agent, the Securities
Intermediary and the Collateral Agent, as the case may be, the Company, when
duly authorized by a Board Resolution, the Purchase Contract Agent, the
Collateral Agent, the Securities Intermediary and the Collateral Agent 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 Units; provided,
however, that no such supplemental agreement shall, without the unanimous
consent of the Holders of each Outstanding Unit adversely affected thereby in
any material respect:

         (a)      change the amount or type of Collateral represented by a Unit
(except for the rights of holders of Corporate Units to substitute the Treasury
Securities for the Pledged Senior Notes or the Pledged Applicable Ownership
Interests, as the case may be, or the rights of Holders of Treasury Units to
substitute Senior Notes or the Applicable Ownership Interests (as specified in
clause (i) of the definition of such term) in the Treasury Portfolio, as
applicable, for the Pledged Treasury Securities), impair the right of the Holder
of any Unit to receive distributions on the Collateral represented thereby or
otherwise adversely affect the Holder's rights in or to such Collateral; or

         (b)      otherwise effect any action that would require the consent of
the Holder of each Outstanding Unit affected thereby pursuant to the Purchase
Contract Agreement if such action were effected by a modification or amendment
of the provisions of the Purchase Contract Agreement; or

         (c)      reduce the percentage of Purchase Contracts the consent of
whose Holders is required for the modification or amendment of the provisions of
this Agreement;

                                       31

<PAGE>

provided that if any amendment or proposal referred to above would adversely
affect only the Corporate Units or only the Treasury Units, then only the
affected class of Holders as of the record date for the Holders entitled to vote
thereon will be entitled to vote on such amendment or proposal, and such
amendment or proposal shall not be effective except with the consent of Holders
of not less than a majority of such class; provided, further, that the unanimous
consent of the Holders of each outstanding Purchase Contract of such class
affected thereby shall be required to approve any amendment or proposal
specified in clauses (a) through (c) above.

         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.

         Section 10.03. Execution Of Amendments. In executing any amendment
permitted by this Article, the Collateral Agent, the Custodial Agent, the
Securities Intermediary and the Purchase Contract Agent shall be entitled to

in relying upon, an Opinion of Counsel stating that the execution of such
amendment is authorized or permitted by this Agreement and that all conditions

in such amendment. If the Company shall so determine, new Certificates so
