Indenture referred to on the reverse hereof, be paid to the person in whose
name this Debenture is registered at the close of business on January 1 or
July 1, as the case may be, next preceding such January 15 or July 15. Payment
of the principal of and interest on this Debenture will be made at the office
or agency of the Corporation in the Borough of Manhattan, The City of New
York, New York; provided, however, that interest may be paid, at the option of
the Corporation, by check mailed to the registered holder hereof at such

Debentures, or in such other manner as the Corporation may agree with the
holder hereof as contemplated by Section 1(d) of the Eighteenth Supplemental
Indenture referred to on the reverse hereof.

hereof and such provisions shall for all purposes have the same effect as
though fully set forth at this place.

any purpose, unless the form of certificate of authentication hereon shall

TRUSTEE'S AUTHENTICATION CERTIFICATE

          THIS IS ONE OF THE DEBENTURES, OF THE SERIES DESIGNATED THEREIN,
DESCRIBED IN THE WITHIN-MENTIONED INDENTURE.

                               FIRST UNION NATIONAL BANK,
                               AS TRUSTEE

                               BY: ______________________________
                                     AUTHORIZED OFFICER

(FORM OF REVERSE OF Series S DEBENTURES)

          This Debenture is one of the Debentures of the Corporation (herein
called the "Debentures"), all duly authorized or from time to time to be duly
authorized and not limited in aggregate principal amount, all issued and to be
issued in one or more series from time to time under and equally secured by a
Collateral Trust Indenture dated as of March 21, 1983, between the Corporation
and First Union National Bank, as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture as hereinafter
defined), as supplemented and amended by a Third Supplemental Indenture
thereto dated as of February 20, 1986, by an Eighth Supplemental Indenture
thereto dated as of May 15, 1990 and by a Seventeenth Supplemental Indenture
thereto dated as of March 10, 1997 and as last supplemented by the Eighteenth
Supplemental Indenture, dated as of July 16, 1998 (said Indenture, as so
supplemented and amended, being herein called the "Indenture"), to which
Indenture and all indentures supplemental thereto reference is hereby made for
a description of the property thereby pledged, the nature and extent of the
security, the rights of the holders of the Debentures in respect of the
security, the rights, duties and immunities of the Trustee and the rights and
obligations of the Corporation in respect of the Debentures, and the terms and
conditions upon which the Debentures are, and are to be, secured. The
Debentures may be issued in series, for various principal sums, may mature at
different times, may bear interest at different rates and may otherwise vary
as in the Indenture provided. This Debenture is one of a series designated as
the "6.52% Collateral Trust Debentures, Series S, Due July 15, 2005" of the
Corporation (herein called the "Series S Debentures."), duly authorized and
lawfully issued in an aggregate principal amount of $75,000,000 under and
secured by the Indenture.

          The provisions of the Indenture may be waived, or modified or
amended by supplemental indenture, to the extent and in the manner provided in
the Indenture, but in certain instances only with the consent of the holders
of a majority in aggregate principal amount of all Debentures at the time
outstanding, and of 66 2/3% in aggregate principal amount of each series of
the Debentures at the time outstanding which is affected by such waiver or
supplemental indenture; provided, however, that, without the written consent
of the holder of this Debenture, no such modification or amendment shall be
made so as to (i) extend the fixed maturity of this Debenture or the time of
payment of interest hereon, or reduce or otherwise modify the terms of payment
of the principal of, or the rate of interest on, this Debenture, or adversely
affect the right of the holder hereof to

<PAGE>

institute suit for the enforcement of any such payment, (ii) permit the
creation of any lien ranking prior to or on a parity with the lien of the
Indenture with respect to, or terminate the lien of the Indenture on, any of
the property covered thereby, or deprive the holder hereof of the security
afforded by the lien of the Indenture or (iii) reduce the percentage of the
aggregate principal amount of Debentures, or of Series S Debentures, required
to authorize any such modification or amendment or any waiver of any provision
of, or default under, the Indenture.

          In case an Event of Default (as defined in the Indenture) shall
occur, the principal of all the Debentures at any such time outstanding under
the Indenture may be declared or may become due and payable upon the
conditions and in the manner and with the effect provided in the Indenture.
The Indenture provides that in certain events such Event of Default and its
consequences may be waived and such declaration may be rescinded by the
holders of outstanding Debentures in the manner provided in the Indenture.

          Any request, demand, authorization, direction, declaration, notice,
consent, waiver or other action by the holder of this Debenture shall bind the
holder of every Debenture issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, in respect of anything done or suffered
to be done by or on behalf of the Trustee or the Corporation in reliance
thereon, whether or not notation of such action is made upon this Debenture.

          The Series S Debentures may not be redeemed prior to maturity.

          The transfer of this Debenture may be registered by the registered
holder hereof or by his duly authorized attorney at the office or agency of
the Corporation in the Borough of Manhattan, the City of New York, New York,
upon surrender of this Debenture for cancellation, accompanied by a written
instrument of transfer in a form approved by the Corporation, duly executed by
the registered holder of this Debenture or by his duly authorized attorney,
and thereupon one or more new Debentures of the same series and aggregate
principal amount will be issued in the name of the transferee or transferees
in exchange herefor without service charge, except that the Corporation may
require payment of a sum sufficient to pay any stamp taxes or other
governmental charges that may be required with respect thereto, as provided in
the Indenture.

          The person in whose name this Debenture shall be registered shall be
deemed the absolute owner hereof for all purposes, and payment of or on
account of the principal of and interest on, this Debenture shall be made only
to or upon the written order of such registered owner or his duly authorized
attorney. All such payments shall satisfy and discharge the liability upon
this Debenture to the extent of the amounts so paid.

          No recourse shall be had for the payment of the principal of, or
interest on, this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplemental thereto, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Corporation or any
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 issue hereof, expressly waived and released. (END OF

its 6.52% Collateral Trust Debentures, Series S, due July 15, 2005 (herein
called the "Series S Debentures"), in an aggregate principal amount not
exceeding $75,000,000, pursuant to a Collateral Trust Indenture dated as of
March 21, 1983, as supplemented and amended by a Third Supplemental Indenture
thereto dated as of February 20, 1986, by an Eighth Supplemental Indenture
thereto dated as of May 15, 1990 and by a Seventeenth Supplemental Indenture
thereto dated as of March 10, 1997 between the Corporation and First Union

as supplemented by the Eighteenth Supplemental Indenture dated as of July 16,
1998, being herein called the "Indenture"). A copy of the Indenture has been
delivered to the Borrower, receipt of which is hereby acknowledged.

          The term "Note" shall mean the 6.52% Demand Promissory Note issued
by the Borrower pursuant to this Agreement, substantially in the form attached

          In addition to the foregoing, the following terms shall in each case

"Participating Subsidiary", "Permitted Indebtedness", "Person", "Pledged
Property", "Series S Debentures", "Trustee" and "Vehicle".

          SECTION 2. Sale of Note. Subject to the terms of this Agreement, the

     provided, however, that the obligation of the Corporation to purchase the
     Note shall be subject to the condition that, concurrently with the
     closing in respect of such purchase, the Corporation shall have issued
     and sold, and shall have received payment for, Series S Debentures in an
     aggregate principal amount equal to the sum of the principal amount of

          SECTION 3. Pledge and Assignment of Note and Agreement. In
consideration of the purchase of the Note by the Corporation and the

Corporation of the Note and this Agreement to the Trustee under and pursuant
to the Indenture as security for the Debentures Outstanding and to be
Outstanding thereunder.

          SECTION 4. Particular Covenants of the Borrower. So long as the Note
shall be outstanding, the Borrower covenants, warrants and agrees as follows:

          (a) Payment of Principal and Interest. The Borrower will duly and
     punctually pay, or cause to be paid, the principal of and interest on,
     the Note according to its terms and the terms of this Agreement.

          (b) Maintenance of Corporate Existence. Subject to the provisions of

     its corporate existence and right to carry on business.

          (c) Borrower a Participating Subsidiary; Validity of Note. The
     Borrower warrants that at the date of this Agreement it is a
     Participating Subsidiary as defined in Section 4 of the Eighth
     Supplemental Indenture dated as of May 15, 1990, and that the Note, when
     delivered to the Corporation will be, and when pledged and assigned to
     the Trustee as security under the Indenture, will continue to be, a legal
     and valid outstanding obligation of the Borrower.

          (d) Further Assurance. The Borrower will execute and deliver, or
     cause to be executed and delivered, all such additional instruments and
     do, or cause to be done, all such additional acts as (i) may be necessary
     or proper to carry out the purposes of this Agreement and to subject the
     Note to the lien of the Indenture, (ii) may be necessary or proper to
     effect the transfer, pledge and assignment of the Note and this Agreement
     to the Trustee or to any successor trustee and to confirm the lien of the
     Indenture on the Note, (iii) may be necessary or proper in connection
     with the granting of the security interest under subsection (f) of this
     Section 4 or (iv) the Trustee or the Corporation may reasonably request
     for any of the foregoing purposes.

          (e) Restrictions on Borrower's Disposition of Property,
     Consolidation, Merger, etc. The Borrower will not sell, transfer or
     otherwise dispose of the beneficial interest in all or substantially all
     its property or assets, or be a party to any consolidation, merger or
     amalgamation; provided, however, that the Borrower may take any such
     action or be such a party if:

               (i) the surviving corporation (if other than the Borrower), or
          the person to whom all, or substantially all, the property and
          assets of the Borrower shall have been transferred, sold or
          otherwise disposed of, shall execute and deliver to the Corporation
          and to the Trustee an agreement of assumption in which such
          surviving corporation or person shall expressly assume the due and
          punctual payment of the principal of and interest on, the Note,
          according to its tenor and effect, and the due and punctual
          performance and observance of all the covenants and conditions of
          the Note and this Agreement which are to be performed or observed by
          the Borrower, with the same effect as if such surviving corporation
          or person had been named herein as a party hereto in lieu of the
          Borrower; and

               (ii) immediately after such transfer, sale or other
          disposition, or consolidation, merger or amalgamation, no default
          shall have occurred and be continuing under this Agreement; and

               (iii) all the voting stock of the surviving corporation

<PAGE>

          shall be owned directly or indirectly by the Corporation. (f)
          Creation of Security Interest. The Borrower will not create or
          permit to exist any claim, lien, security interest or other
          encumbrance on any of its Vehicles, or on its interest as lessor in
          any lease agreement relating to its Vehicles, except:

               (i) lessees' interests in Vehicles under any such lease
          agreement; and

               (ii) liens, security interests or other encumbrances for taxes
          which are not delinquent or which are being contested in good faith
          or of mechanics or materialmen arising in the ordinary course of
          business in respect of obligations which are not overdue or which
          are being contested in good faith; unless (x) such claim, lien,
          security interest or other encumbrance is for the benefit of a
          holder or holders of Equipment Indebtedness and (y) prior to or
          simultaneously with the inception of any such claim, lien, security
          interest or other encumbrance, the Borrower shall have executed and
          delivered to a Security Trustee (as hereinafter defined), a security
          agreement or security agreements and such other documents as the
          Security Trustee may reasonably request, each in form and substance
          satisfactory to the Trustee, granting to the Security Trustee the
          right to perfect a security interest in such Vehicles of the
          Borrower, such security interest, when perfected, to be for the
          equal and ratable benefit of the Trustee, as holder of the Notes,
          and such other holder or holders of Equipment Indebtedness. Such
          security agreement or security agreements may provide, at the option
          of the Borrower, that the security interest granted to the Security
          Trustee shall terminate upon the termination of all other claims,
          liens, security interests and other encumbrances for the benefit of
          such other holder or holders of Equipment Indebtedness. The Security
          Trustee shall be such Person as may be selected by the Borrower or
          any such holder of Equipment Indebtedness and who shall be entitled
          to act without qualification or who shall qualify to act as such
          under the Trust Indenture Act of 1939.

          SECTION 5. Payments of Principal and Interest. So long as the Note
shall be pledged with the Trustee under the Indenture, any payment of
principal or interest on the Note, or any payments to be made pursuant to
Section 6(a), shall be paid to the Trustee in Chicago Clearing House funds at
least one business day prior to the dates on which the Corporation would be
required to make related payments under the Indenture with respect to the
relevant Debentures. The Trustee shall apply such payments in accordance with
the provisions of the Indenture.

          SECTION 6. Prepayment of Note.

         (a) Prepayments Pursuant to Section 7.14 of the Original Indenture.
    So long as the Note shall be pledged with the Trustee under the Indenture,
    the Borrower shall pay, or cause to be paid, to the Trustee, as
    prepayments on the Note, amounts which may be required to be paid by the
    Borrower pursuant to Section 7.14 of the Original Indenture. Any such
    amounts shall be paid as provided in Section 5 of this Agreement and shall
    be applied as payment or prepayment on the Note in accordance with
    subsection (c) of this Section 6.

         (b) Notice of Certain Prepayments. If the Corporation is required to
    make payments pursuant to Section 7.14 of the Original Indenture, the
    Corporation shall give notice thereof to the Borrower, which notice shall
    state the circumstances under which such payments are to be made. Such
    notice shall be given not later than the first date on which the
    Corporation is required to give notice to the Trustee or to take any other
    action with respect to such payments. Failure to give any such

<PAGE>

     notice to the Borrower or any defect therein shall not, however, affect
     the obligation of the Borrower to make the payments required under
     subsection (a) of this Section 6.

          (c) Prepayments on Principal Amount of Note. All payments made by
     the Borrower, or for the account of the Borrower, pursuant to this
     Section 6 shall be applied or credited as prepayments on the principal
     amount of the Note on the date such payments are received by the Trustee;
     provided, however, that to the extent a portion of such payments or
     moneys shall be applied or applicable by the Trustee, directly or
     indirectly, towards the payment of any interest or premium in respect of
     Debentures, such portion shall not be applied or credited as prepayments
     on the principal amount of the Note. It is the intention of this Section
     6 that the principal amount of the Note shall be appropriately adjusted
     at appropriate times in order that the obligations to pay principal,
     premium, if any, and interest contained in all the Notes of all
     Participating Subsidiaries shall be sufficient, after giving effect to
     any moneys then held by the Trustee under Section 9.01 of the Original
     Indenture, in the aggregate, to pay all principal, premium, if any, and
     interest on all Debentures then Outstanding as the same become due and
     payable.

          (d) Corporation To Make Certain Payments. When and if the Borrower
     shall make any prepayments provided for in this Section 6, the
     Corporation shall promptly make such payments and take such other action
     with respect to the Debentures as shall be required to be made or taken
     by the Corporation in accordance with and pursuant to this Agreement and
     the Indenture.

          SECTION 7. Presentment of Note Not Required. So long as the Note
shall be pledged with the Trustee under the Indenture, payments of principal
thereof and interest thereon, shall be made without need for any presentment
of the Note, but payments of principal shall be noted thereon by the Trustee.

          SECTION 8. Amendments, Consents and Waivers. So long as the Note
shall be pledged with the Trustee under the Indenture (a) this Agreement may
be modified, altered, supplemented or amended upon the execution and delivery
of a written amendment by the parties hereto pursuant to Article XVIII of the
Original Indenture, (b) any covenant or other condition of this Agreement may
be waived as and to the extent permitted in Section 11.02 of the Original
Indenture and (c) any default under this Agreement and its consequences may be
waived as and to the extent permitted in said Section 11.02 of the Original
Indenture.

          SECTION 9. Loss, Theft, etc. of Note. Upon receipt of evidence of
the loss, theft, destruction or mutilation of the Note and upon delivery of
indemnity reasonably satisfactory to the Borrower (it being understood that
the written agreement of the Trustee to indemnify the Borrower shall
constitute such indemnity) and, in the case of any such mutilation, upon
surrender and cancellation of the mutilated Note, and, in any case, upon
reimbursement to the Borrower of any reasonable expense incidental thereto,
the Borrower shall make and deliver a new Note of like tenor, in lieu of such
lost, stolen or destroyed Note or in exchange for such mutilated Note.

          SECTION 10. Remedies. The holder of the Note, being a party to, or
an assignee of, this Agreement, shall be entitled and empowered to institute
any suits, actions or proceedings at law, in equity or otherwise, whether for
the specific performance of any covenant or agreement contained herein or in
the Note or in aid of the exercise of any power granted herein or in the Note,
or may proceed to enforce the payment of the Note after demand, or to enforce
any other legal or equitable right as the holder of the Note, or may proceed
to take any action authorized or permitted under the terms of the Indenture
with respect to the Note or under any applicable law.

<PAGE>

          SECTION 11. Remedies Cumulative; Delay or Omission Not a Waiver.
Every remedy given hereunder to the holder of the Note shall not be exclusive
of any other remedy or remedies, and every such remedy shall be cumulative and
in addition to every other remedy given hereunder or now or hereafter given by
statute, law, equity or otherwise. No course of dealing between the Borrower
and the Corporation or the Borrower and the holder of the Note or any delay or
omission on the part of the Corporation or such holder to exercise any right,
remedy or power accruing upon any default hereunder shall impair any such
right, remedy or power or shall be construed to be a waiver of any such
default or of any right of the Corporation or such holder or acquiescence
therein. Every right, remedy and power given hereunder to the Corporation or
to the holder of the Note may be exercised from time to time and as often as
may be deemed expedient by the Corporation or such holder.

          SECTION 12. Successors and Assigns. All the covenants, warranties
and agreements contained in this Agreement by or on behalf of the Corporation,
the Borrower or the holder of the Note shall bind and inure to the benefit of
their respective successors and assigns, whether so expressed or not.

          SECTION 13. Notices. All notices, presentments and demands to or
upon the Borrower in respect of the Note or this Agreement may be delivered or
mailed to the Borrower at One Rollins Plaza, P.O. Box 1791, Wilmington,
Delaware 19899, or at such other address as the Borrower may specify from time

          SECTION 14. Payment or Notice on Saturday, Sunday, Legal Holiday. If
the date of any payment or the giving of any notice under the Note or this
Agreement shall be (a) a Saturday, a Sunday or a legal holiday at the place
where payment is to be made or notice is to be given or (b) a day on which
banking institutions at the place where payment is to be made or notice is to
be given are authorized by law to remain closed, then such payment or notice
shall be made not later than the next preceding business day which shall not
be a day specified in (a) or (b) above.

          SECTION 15. Separability of Provisions. In case any one or more of
the provisions contained in this Agreement or in the Note should be invalid,
illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby.

          SECTION 16. Counterparts. This Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall be
an original, and all such counterparts shall together constitute but one and
the same instrument.

          SECTION 17. Applicable Law. This Agreement shall be construed in
accordance with and governed by the laws of the State of Delaware.

          IN WITNESS WHEREOF, each of the parties hereto has caused this

                   (FORM OF REVERSE OF Series T DEBENTURES)

     This Debenture is one of the Debentures of the Corporation (herein called
the "Debentures"), all duly authorized or from time to time to be duly
authorized and not limited in aggregate principal amount, all issued and to be
issued in one or more series from time to time under and equally secured by a
Collateral Trust Indenture dated as of March 21, 1983, between the Corporation
and First Union National Bank, as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture as hereinafter
defined), as supplemented and amended by a Third Supplemental Indenture
thereto dated as of February 20, 1986, by an Eighth Supplemental Indenture,
dated as of May 15, 1990, by a Seventeenth Supplemental Indenture, dated as of
March 10, 1997, and as last supplemented by the Nineteenth Supplemental
Indenture, dated as of April 5, 1999 (said Indenture, as so supplemented and
amended, being herein called the "Indenture"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the property thereby pledged, the nature and extent of the security, the
rights of the holders of the Debentures in respect of the security, the
rights, duties and immunities of the Trustee and the rights and obligations of
the Corporation in respect of the Debentures, and the terms and conditions
upon which the Debentures are, and are to be, secured. The Debentures may be
issued in series, for various principal sums, may mature at different times,
may bear interest at different rates and may otherwise vary as in the
Indenture provided. This Debenture is one of a series designated as the "6.75%
Collateral Trust Debentures, Series T, due April 5, 2006" of the Corporation
(herein called the "Series T Debentures"), duly authorized and lawfully issued
in an aggregate principal amount of $100,000,000 under and secured by the
Indenture.

<PAGE>

     The provisions of the Indenture may be waived, or modified or amended by
supplemental indenture, to the extent and in the manner provided in the
Indenture, but in certain instances only with the consent of the holders of a
majority in aggregate principal amount of all Debentures at the time
outstanding, and of 66 2/3% in aggregate principal amount of each series of
the Debentures at the time outstanding which is affected by such waiver or
supplemental indenture; provided, however, that, without the written consent
of the holder of this Debenture, no such modification or amendment shall be
made so as to (i) extend the fixed maturity of this Debenture or the time of
payment of interest hereon, or reduce or otherwise modify the terms of payment
of the principal of, or the rate of interest on, this Debenture, or adversely
affect the right of the holder hereof to institute suit for the enforcement of
any such payment, (ii) permit the creation of any lien ranking prior to or on
a parity with the lien of the Indenture with respect to, or terminate the lien
of the Indenture on, any of the property covered thereby, or deprive the
holder hereof of the security afforded by the lien of the Indenture or (iii)
reduce the percentage of the aggregate principal amount of Debentures, or of
Series T Debentures, required to authorize any such modification or amendment
or any waiver of any provision of, or default under, the Indenture.

     In case an Event of Default (as defined in the Indenture) shall occur,
the principal of all the Debentures at any such time outstanding under the
Indenture may be declared or may become due and payable upon the conditions
and in the manner and with the effect provided in the Indenture. The Indenture
provides that in certain events such Event of Default and its consequences may
be waived and such declaration may be rescinded by the holders of outstanding
Debentures in the manner provided in the Indenture.

     Any request, demand, authorization, direction, declaration, notice,
consent, waiver or other action by the holder of this Debenture shall bind the
holder of every Debenture issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, in respect of anything done or suffered
to be done by or on behalf of the Trustee or the Corporation in reliance
thereon, whether or not notation of such action is made upon this Debenture.

     The Series T Debentures may not be redeemed prior to maturity.

     The transfer of this Debenture may be registered by the registered holder
hereof or by his duly authorized attorney at the office or agency of the
Corporation in the Borough of Manhattan, the City of New York, New York, upon
surrender of this Debenture for cancellation, accompanied by a written
instrument of transfer in a form approved by the Corporation, duly executed by
the registered holder of this Debenture or by his duly authorized attorney,
and thereupon one or more new Debentures of the same series and aggregate
principal amount will be issued in the name of the transferee or transferees
in exchange herefor without service charge, except that the Corporation may
require payment of a sum sufficient to pay any stamp taxes or other
governmental charges that may be required with respect thereto, as provided in
the Indenture.

     The person in whose name this Debenture shall be registered shall be
deemed the absolute owner hereof for all purposes, and payment of or on
account of the principal of and interest on, this Debenture shall be made only
to or upon the written order of such registered owner or his duly authorized
attorney. All such payments shall satisfy and discharge the liability upon
this Debenture to the extent of the amounts so paid.

     No recourse shall be had for the payment of the principal of, or interest
on, this Debenture, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture or any indenture
supplemental thereto, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Corporation or any
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 issue hereof, expressly waived and released.

     WHEREAS, the Borrower desires to borrow from the Corporation, and the

     SECTION 2. Sale of Note. Subject to the terms of this Agreement, the

     The sale of the Note will take place immediately after the execution and

     to effect the issuance of Series T Debentures referred to in Section 1,
     and

          (b) by the Corporation to the Borrower of a certified or official
     bank check or checks in clearing house funds (or in such other form as
     shall be acceptable to the Borrower) in an amount equal to $75,000,000;
     provided, however, that the obligation of the Corporation to purchase the
     Note shall be subject to the condition that, concurrently with the

     and sold, and shall have received payment for, Series T Debentures in an
     aggregate principal amount equal to the sum of the principal amount of
     the Note.

     SECTION 3. Pledge and Assignment of Note and Agreement. In consideration

shall be outstanding, the Borrower covenants, warrants and agrees as follows:

<PAGE>

          (a) Payment of Principal and Interest. The Borrower will duly and
     punctually pay, or cause to be paid, the principal of and interest on,

     Borrower warrants that at the date of this Agreement it is a
     Participating Subsidiary as defined in Section 4 of the Eighth
     Supplemental Indenture dated as of May 15, 1990, and that the Note, when
     delivered to the Corporation will be, and when pledged and assigned to
     the Trustee as security under the Indenture, will continue to be, a legal
     and valid outstanding obligation of the Borrower.

          (d) Further Assurance. The Borrower will execute and deliver, or
     cause to be executed and delivered, all such additional instruments and

     or proper to carry out the purposes of this Agreement and to subject the
     Note to the lien of the Indenture, (ii) may be necessary or proper to
     effect the transfer, pledge and assignment of the Note and this Agreement
     to the Trustee or to any successor trustee and to confirm the lien of the
     Indenture on the Note, (iii) may be necessary or proper in connection
     with the granting of the security interest under subsection (f) of this
     Section 4 or (iv) the Trustee or the Corporation may reasonably request
     for any of the foregoing purposes.

          (e) Restrictions on Borrower's Disposition of Property,
     Consolidation, Merger, etc. The Borrower will not sell, transfer or
     otherwise dispose of the beneficial interest in all or substantially all
     its property or assets, or be a party to any consolidation, merger or
     amalgamation; provided, however, that the Borrower may take any such
     action or be such a party if:

               (i) the surviving corporation (if other than the Borrower), or
          the person to whom all, or substantially all, the property and
          assets of the Borrower shall have been transferred, sold or
          otherwise disposed of, shall execute and deliver to the Corporation
          and to the Trustee an agreement of assumption in which such
          surviving corporation or person shall expressly assume the due and
          punctual payment of the principal of and interest on, the Note,
          according to its tenor and effect, and the due and punctual
          performance and observance of all the covenants and conditions of
          the Note and this Agreement which are to be performed or observed by
          the Borrower, with the same effect as if such surviving corporation
          or person had been named herein as a party hereto in lieu of the
          Borrower; and

               (ii) immediately after such transfer, sale or other
          disposition, or consolidation, merger or amalgamation, no default
          shall have occurred and be continuing under this Agreement; and

               (iii) all the voting stock of the surviving corporation shall
          be owned directly or indirectly by the Corporation.

          (f) Creation of Security Interest. The Borrower will not create or
     permit to exist any claim, lien, security interest or other encumbrance
     on any of its Vehicles, or on its interest as lessor in any lease
     agreement relating to its Vehicles, except:

               (i) lessees' interests in Vehicles under any such lease
          agreement; and

               (ii) liens, security interests or other encumbrances for taxes
          which are not delinquent or which are being contested in good faith
          or of mechanics or materialmen arising in the ordinary course of
          business in respect of obligations which are not overdue or which
          are being contested in good faith; unless (x) such claim, lien,
          security interest or other encumbrance is for the benefit of a
          holder or holders of Equipment Indebtedness and (y) prior to or
          simultaneously with the inception of any such claim, lien, security
          interest or other encumbrance, the Borrower shall have executed and
          delivered to a Security Trustee (as hereinafter defined), a security
          agreement or security agreements and such other documents as the
          Security Trustee may reasonably request, each in form and substance
          satisfactory to the Trustee, granting to the Security Trustee the
          right to perfect a security interest in such Vehicles of the
          Borrower, such security interest, when perfected, to be

<PAGE>

          for the equal and ratable benefit of the Trustee, as holder of the
          Notes, and such other holder or holders of Equipment Indebtedness.
          Such security agreement or security agreements may provide, at the
          option of the Borrower, that the security interest granted to the
          Security Trustee shall terminate upon the termination of all other
          claims, liens, security interests and other encumbrances for the
          benefit of such other holder or holders of Equipment Indebtedness.
          The Security Trustee shall be such Person as may be selected by the
          Borrower or any such holder of Equipment Indebtedness and who shall
          be entitled to act without qualification or who shall qualify to act
          as such under the Trust Indenture Act of 1939.

     SECTION 5. Payments of Principal and Interest. So long as the Note shall
be pledged with the Trustee under the Indenture, any payment of principal or
interest on the Note, or any payments to be made pursuant to Section 6(a),
shall be paid to the Trustee in Chicago Clearing House funds at least one
business day prior to the dates on which the Corporation would be required to
make related payments under the Indenture with respect to the relevant
Debentures. The Trustee shall apply such payments in accordance with the
provisions of the Indenture.

     SECTION 6. Prepayment of Note.

          (a) Prepayments Pursuant to Section 7.14 of the Original Indenture.
     So long as the Note shall be pledged with the Trustee under the
     Indenture, the Borrower shall pay, or cause to be paid, to the Trustee,
     as prepayments on the Note, amounts which may be required to be paid by
     the Borrower pursuant to Section 7.14 of the Original Indenture. Any such
     amounts shall be paid as provided in Section 5 of this Agreement and
     shall be applied as payment or prepayment on the Note in accordance with
     subsection (c) of this Section 6.

          (b) Notice of Certain Prepayments. If the Corporation is required to
     make payments pursuant to Section 7.14 of the Original Indenture, the
     Corporation shall give notice thereof to the Borrower, which notice shall
     state the circumstances under which such payments are to be made. Such
     notice shall be given not later than the first date on which the
     Corporation is required to give notice to the Trustee or to take any
     other action with respect to such payments. Failure to give any such
     notice to the Borrower or any defect therein shall not, however, affect
     the obligation of the Borrower to make the payments required under
     subsection (a) of this Section 6.

          (c) Prepayments on Principal Amount of Note. All payments made by
     the Borrower, or for the account of the Borrower, pursuant to this
     Section 6 shall be applied or credited as prepayments on the principal
     amount of the Note on the date such payments are received by the Trustee;
     provided, however, that to the extent a portion of such payments or
     moneys shall be applied or applicable by the Trustee, directly or
     indirectly, towards the payment of any interest or premium in respect of
     Debentures, such portion shall not be applied or credited as prepayments
     on the principal amount of the Note. It is the intention of this Section
     6 that the principal amount of the Note shall be appropriately adjusted
     at appropriate times in order that the obligations to pay principal,
     premium, if any, and interest contained in all the Notes of all
     Participating Subsidiaries shall be sufficient, after giving effect to
     any moneys then held by the Trustee under Section 9.01 of the Original
     Indenture, in the aggregate, to pay all principal, premium, if any, and
     interest on all Debentures then Outstanding as the same become due and
     payable.

          (d) Corporation To Make Certain Payments. When and if the Borrower
     shall make any prepayments provided for in this Section 6, the
     Corporation shall promptly make such payments and take such other action
     with respect to the Debentures as shall be required to be made or taken
     by the Corporation in accordance with and pursuant to this Agreement and
     the Indenture.

     SECTION 7. Presentment of Note Not Required. So long as the Note shall be
pledged with the Trustee under the Indenture, payments of principal thereof
and interest thereon, shall be made without need for any presentment of the
Note, but payments of principal shall be noted thereon by the Trustee.

     SECTION 8. Amendments, Consents and Waivers. So long as the Note shall be
pledged with the Trustee under the Indenture (a) this Agreement may be
modified, altered, supplemented or amended upon the execution and delivery of
a written amendment by the parties hereto pursuant to Article XVIII of the
Original Indenture, (b) any covenant or other condition of this Agreement may
be waived as and to the extent

<PAGE>

permitted in Section 11.02 of the Original Indenture and (c) any default under
this Agreement and its consequences may be waived as and to the extent
permitted in said Section 11.02 of the Original Indenture.

     SECTION 9. Loss, Theft, etc. of Note. Upon receipt of evidence of the
loss, theft, destruction or mutilation of the Note and upon delivery of
indemnity reasonably satisfactory to the Borrower (it being understood that
the written agreement of the Trustee to indemnify the Borrower shall
constitute such indemnity) and, in the case of any such mutilation, upon
surrender and cancellation of the mutilated Note, and, in any case, upon
reimbursement to the Borrower of any reasonable expense incidental thereto,
the Borrower shall make and deliver a new Note of like tenor, in lieu of such
lost, stolen or destroyed Note or in exchange for such mutilated Note.

     SECTION 10. Remedies. The holder of the Note, being a party to, or an
assignee of, this Agreement, shall be entitled and empowered to institute any
suits, actions or proceedings at law, in equity or otherwise, whether for the
specific performance of any covenant or agreement contained herein or in the
Note or in aid of the exercise of any power granted herein or in the Note, or
may proceed to enforce the payment of the Note after demand, or to enforce any
other legal or equitable right as the holder of the Note, or may proceed to
take any action authorized or permitted under the terms of the Indenture with
respect to the Note or under any applicable law.

     SECTION 11. Remedies Cumulative; Delay or Omission Not a Waiver. Every
remedy given hereunder to the holder of the Note shall not be exclusive of any
other remedy or remedies, and every such remedy shall be cumulative and in
addition to every other remedy given hereunder or now or hereafter given by
statute, law, equity or otherwise. No course of dealing between the Borrower
and the Corporation or the Borrower and the holder of the Note or any delay or
omission on the part of the Corporation or such holder to exercise any right,
remedy or power accruing upon any default hereunder shall impair any such
right, remedy or power or shall be construed to be a waiver of any such
default or of any right of the Corporation or such holder or acquiescence
therein. Every right, remedy and power given hereunder to the Corporation or
to the holder of the Note may be exercised from time to time and as often as
may be deemed expedient by the Corporation or such holder.

     SECTION 12. Successors and Assigns. All the covenants, warranties and
agreements contained in this Agreement by or on behalf of the Corporation, the
