      (except, however, that the Security Agent may surrender possession to
      the issuer of any such U.S. Government Obligations for the purposes
      of effecting assignment, crediting interest, or reinvesting such
      security or reducing such security to cash) and to be the registered

      in accordance with Section 2(c)(i) hereof, (C) to invest and reinvest

delivery of all funds and U.S. Government Obligations maintained by the
Security Agent hereunder and copies of all books, records, plans and other
documents in the Security Agent's possession relating to such funds or U.S.
Government Obligations or this Agreement to a successor Security Agent
appointed by the Company and (ii) the Company, the Collateral Agent acting
on behalf of the 2001 Trustee and the 2000 Trustee and such successor
Security Agent entering into this Agreement or any written successor
agreement no less favorable to the interests of the holders of the Notes
and the Collateral Agent acting on behalf of the 2001 Trustee and the 2000
Trustee than this Agreement; and the Security Agent shall thereupon be
discharged of all obligations under this Agreement and shall have no
further duties, obligations or responsibilities in connection herewith. If
a successor Security Agent has not been appointed or has not accepted such
appointment within 30 days after notice of resignation is given to the
Company, the Security Agent may apply to a court of competent jurisdiction
for the appointment of a successor Security Agent and no such resignation
shall take effect until such appointment of a successor Security Agent is
made and the terms of the second sentence of this Section 2(d) have been
complied with.

is reduced to zero, the Security Agent shall, as soon as practicable,
deliver to the Company, to the 2001 Trustee, the 2000 Trustee and to the
Collateral Agent a written notice that the balance in the Security Account
has been reduced to zero.

            (f) Representations of Security Agent. The Security Agent

Company or the Collateral Agent in compliance with the provisions of this
Agreement without being required to determine the authenticity or the
correctness of any fact stated therein or the propriety or validity of
service thereof. The Security Agent may act in reliance upon any instrument
comporting with the provisions of this Agreement or signature believed by

Agent shall be entitled to refuse to act until either any conflicting or
adverse claims or demands shall have been finally determined by a court of
competent jurisdiction or settled by agreement between the conflicting
claimants as evidenced in a writing, satisfactory to the Security Agent, in
which event the Security Agent shall act in accordance with such
determination or agreement.

to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder.

proceedings of any kind and shall not be required to initiate or defend any
legal proceedings which may be instituted against it in respect of the
subject matter of this Agreement. If the Security Agent does elect to act
it will do so only to the extent that it is indemnified to its satisfaction
against the cost and expense of such defense or initiation.

misconduct of any of the foregoing persons. The Security Agent shall not be
entitled to recover any costs arising under this Section 5 from funds
available in the Security Account. The provisions of this Section shall
survive any termination, satisfaction or discharge of this Agreement as

action, expense or claim is directly attributable to the gross negligence
or wilful misconduct of any of the foregoing persons. The Collateral Agent
shall not be entitled to recover any costs arising under this Section 5

Account for the benefit of the Collateral Agent acting for the equal and
ratable benefit of the 2001 Trustee for the benefit of the holders of the
2001 Notes and the 2000 Trustee for the benefit of the 2000 Notes to the
extent specifically required herein, (B) maintain, or cause its agent
within the State of New York to maintain, possession of all certificated
U.S. Government Obligations purchased hereunder that are physically
possessed by the Security Agent in order for the Collateral Agent acting
for the equal and ratable benefit of the 2001 Trustee for the benefit of
the holders of the 2001 Notes and the 2000 Trustee for the benefit of the
2000 Notes to enjoy a continuous perfected first priority security interest
therein under the laws of the State of New York (the Company hereby
agreeing that in the event any certificated U.S. Government Obligations are
in the possession of the Company or a third party, the Company shall use
its commercially reasonable efforts to deliver all such certificates to the
Security Agent for credit to the Security Account for the benefit of the
Collateral Agent acting for the equal and ratable benefit of the 2001
Trustee for the benefit of the holders of the 2001 Notes and the 2000
Trustee for the benefit of the 2000 Notes) and (C) maintain the Collateral
free and clear of all liens, security interests, safekeeping or other
charges, demands and claims against the Security Agent of any nature now or
hereafter existing in favor of anyone other than the Collateral Agent; (ii)
promptly notify the Collateral Agent if the Security Agent receives written
notice that any person other than the Collateral Agent has a lien or
security interest upon any portion of the Collateral and (iii) in addition
to disbursing amounts held in escrow pursuant to any Payment Notice and
Disbursement Requests given to it by the Collateral Agent pursuant to
Section 3, upon receipt of both (A) written notice from the Collateral
Agent that either (x) as a result of an Event of Default the indebtedness
represented by the 2000 Notes or the 2001 Notes has been accelerated or (y)
the maturity date of the 2000 Notes or the 2001 Notes has occurred, under
either of the Indentures, and (B) direction from the Collateral Agent to
disburse all Available Funds to the applicable Trustee, as promptly as
practicable, after following the procedures set forth in the fourth
paragraph of Section 4, the Security Agent shall disburse all funds held in
the Security Account to the applicable Trustee and transfer title to all
U.S. Government Obligations held by the Security Agent hereunder to the
Collateral Agent acting for the equal and ratable benefit of the 2001
Trustee for the benefit of the holders of the 2001 Notes and the 2000
Trustee for the benefit of the 2000 Notes. The lien and security interest
provided for by this Section 6 shall automatically terminate and cease as
to, and shall not extend or apply to, and the Collateral Agent shall have
no security interest in, any funds disbursed by the Security Agent to the
Company pursuant to this Agreement. The Security Agent shall act solely as
the Collateral Agent's agent in connection with the duties under this
Section 6, notwithstanding any other provision contained in this Agreement,
without any right to receive compensation from the Collateral Agent and
without any authority to obligate the Collateral Agent or to compromise or
pledge its security interest hereunder.

            (d) Any money and U.S. Government Obligations collected by the
2001 Trustee or the 2000 Trustee pursuant to Section 6(c)(iii) shall be
applied as provided in the Indentures.

            (e) The Company will execute and deliver to the Collateral
Agent such instruments and documents as may be required or as the
Collateral Agent may reasonably deem necessary or advisable to confirm or
perfect the rights of the Collateral Agent under this Agreement and the
Collateral Agent's interest in the Collateral. The Company will take all
necessary action to preserve and protect the security interest created
hereby as a lien and encumbrance upon the Collateral.

            (f) The Company hereby appoints the Collateral Agent as its
attorney-in-fact effective upon either (i) the acceleration of the
indebtedness represented by the 2000 Notes or the 2001 Notes due to the
occurrence of an Event of Default under either of the Indentures or (ii)
the maturity of the 2000 Notes or the 2001 Notes, with full power of
substitution to do any act which the Company is obligated hereto to do, and
the Collateral Agent may exercise such rights as the Company might exercise
with respect to the Collateral and to take any action in the Company's name
to protect the Collateral Agent's security interest hereunder. Prior to the
occurrence of an Event of Default known to the Collateral Agent, the
Collateral Agent shall have no duty or obligation to verify or maintain the
perfection of any security interest created hereby.

      7. Collateral Agent.

            Limitation of the Collateral Agent's Liability;
Responsibilities of the Collateral Agent. The Collateral Agent's
responsibility and liability under this Agreement shall be limited as
follows: (i) the Collateral Agent does not represent, warrant or guaranty
to the holders of the Notes from time to time the performance of either the
2001 Trustee or the 2000 Trustee; (ii) the Collateral Agent shall have no
responsibility to the Company or the 2001 Trustee or the 2000 Trustee or
the holders of the Notes from time to time as a consequence of the
performance by the Collateral Agent hereunder, except for any gross
negligence or wilful misconduct of the Collateral Agent and except with
respect to claims based upon such gross negligence or wilful misconduct
that are successfully asserted against the Collateral Agent; (iii) the 2001
Trustee and the 2000 Trustee shall remain solely responsible for all
aspects of their respective business and conduct; and (iv) the Collateral
Agent is not obligated to supervise, inspect, or inform the Company or any
third party of any matter referred to above.

            No implied covenants or obligations shall be inferred from this
Agreement against the Collateral Agent, nor shall the Collateral Agent be
bound by the provisions of any agreement beyond the specific term hereof.
Specifically and without limiting the foregoing, the Collateral Agent shall
in no event have any liability in connection with its capacity as
Collateral Agent or the efforts of the 2001 Trustee for the benefit of the
holders of the 2001 Notes and the efforts of the 2000 Trustee for the
benefit of the 2000 Notes, of any funds or U.S. Government Obligations held
by it hereunder, including without limitation any liability for any delay
not resulting from gross negligence or wilful misconduct in such capacity
as Collateral Agent or the efforts of the 2001 Trustee for the benefit of
the holders of the 2001 Notes and the benefit of the 2000 Trustee for the
benefit of the 2000 Notes, or for any loss of principal or income incident
to any such delay.

            The Collateral Agent shall be entitled to rely upon any
judicial order or judgment, upon any written Opinion of Counsel or upon any
certification, instruction, notice, or other writing delivered to it by the
Company in compliance with the provisions of this Agreement without being
required to determine the authenticity or the correctness of any fact
stated therein or the propriety or validity of service thereof. The
Collateral Agent may act in reliance upon any instrument comporting with
the provisions of this Agreement or signature believed by it to be genuine
and may assume that any person purporting to give notice or receipt or
advice or make any statement or execute any document in connection with the
provisions hereof has been duly authorized to do so.

            At any time, the Collateral Agent may request in writing an
instruction in writing from either the 2001 Trustee or the 2000 Trustee,
and may at its own option include in such request the course of action it
proposes to take and the date on which it proposes to act, regarding any
matter arising in connection with its duties and obligations hereunder;
provided, however, that the Collateral Agent shall state in such request
that it believes in good faith that such proposed course of action is
consistent with another identified provision of this Agreement. The
Collateral Agent shall not be liable to either the 2001 Trustee or the 2000
Trustee for acting without either the 2001 Trustee's Consent or the 2000
Trustee's Consent in accordance with such a proposal on or after the date
specified therein if (i) the specified date is at least two Business Days
after the Company receives the Security Agent's request for instructions
and its proposed course of action, which instructions shall have been
delivered to the Company at least two Business Days prior to such action
and (ii) prior to so acting, the Security Agent has not received the
written instructions requested from the Company, which instructions shall
have been delivered to the Company at least two Business Days prior to such
action.

            The Collateral Agent may act pursuant to the written advice of
counsel chosen by it with respect to any matter relating to this Agreement
and (subject to this Section 7) shall not be liable for any action taken or
omitted in accordance with such advice.

            The Collateral Agent shall not be called upon 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 credited
hereunder.

            In the event of any ambiguity in the provisions of this
Agreement with respect to any funds or property credited hereunder, the
Collateral Agent shall be entitled to refuse to comply with any and all
claims, demands or instructions with respect to such property or funds, and
the Collateral Agent shall not be or become liable for its failure or
refusal to comply with conflicting claims, demands or instructions. The
Collateral Agent shall be entitled to refuse to act until either any
conflicting or adverse claims or demands shall have been finally determined
by a court of competent jurisdiction or settled by agreement between the
conflicting claimants as evidenced in a writing, satisfactory to the
Collateral Agent, in which event the Collateral Agent shall act in
accordance with such determination or agreement.

            No provision of this Agreement shall require the Collateral
Agent to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder.

            The Collateral Agent shall not be required to institute legal
proceedings of any kind and shall not be required to initiate or defend any
legal proceedings which may be instituted against it in respect of the
subject matter of this Agreement. If the Collateral Agent does elect to act
it will do so only to the extent that it is indemnified to its satisfaction
against the cost and expense of such defense or initiation.

      8. Termination. This Agreement shall terminate automatically
following disbursement of all funds remaining in the Security Account
(including U.S. Government Obligations), unless sooner terminated by
agreement of the parties hereto (in accordance with the terms hereof and
not in violation of either of the Indentures); provided, however, that the
obligations of the Company under Section 5 (and any existing claims
thereunder) shall survive termination of this Agreement or the resignation
of the Security Agent.

      9. Miscellaneous.

            (a) Waiver. Any party hereto may specifically waive any breach
of this Agreement by any other party, but no such waiver shall be deemed to
have been given unless such waiver is in writing, signed by the waiving
party and specifically designating the breach waived, nor shall any such
waiver constitute a continuing waiver of similar or other breaches.

            (b) Invalidity. If for any reason whatsoever any one or more of
the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of rendering any of the other
provisions of this Agreement inoperative, unenforceable or invalid, and the
inoperative, unenforceable or invalid provision shall be construed as if it
were written so as to effectuate, to the maximum extent possible, the
parties' intent.

            (c) Assignment; Successors. This Agreement is personal to the
parties hereto, and the rights and duties of any party hereunder shall not
be assignable except with the prior written consent of each of the other
parties. Notwithstanding the foregoing, this Agreement shall inure to and
be binding upon the parties and their successors and permitted assigns.

            (d) Benefit. The parties hereto and their successors and
permitted assigns, but no others, shall be bound hereby and entitled to the
benefits hereof; provided, however, that the holders of the Notes and their
permitted assigns shall be entitled to the benefits hereof and to enforce
this Agreement in accordance with the terms of the applicable Indenture.

            (e) Time. Time is of the essence of each provision of this
Agreement.

            (f) Entire Agreement; Amendments. This Agreement, the
Indentures and the terms of the Notes thereunder contain the entire
agreement among the parties with respect to the subject matter hereof and
supersede any and all prior agreements, understandings and commitments,
whether oral or written. This Agreement may be amended only by a writing
signed by a duly authorized representative of each party hereto.
