certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

          (c)  The ownership of Securities shall be proved by the Security
Register.

          (d)  Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Issuer in reliance thereon, whether or not notation of such action is made upon
such Security.

or Act of the Holders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with,

          (1)  the Trustee by any Holder or by the Issuer shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office and, unless otherwise
     herein expressly provided, any such document shall be deemed to be
     sufficiently made, given, furnished or filed upon its receipt by a
     Responsible Officer of the Trustee, or

          (2)  the Issuer by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Issuer addressed
     to it at the address of its principal office specified in the first
     paragraph of this instrument or at any other address previously furnished
     in writing to the Trustee by the Issuer.

SECTION 1.06.  Notice to Holders; Waiver.
               -------------------------

notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders.  Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive

<PAGE>

                                                                              14

such notice, either before or after the event, and such waiver shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 1.07.  Conflict with Trust Indenture Act.
               ---------------------------------

          If any provision hereof limits, qualifies or conflicts with the duties
imposed by any of Sections 310 to 317, inclusive, of the Trust Indenture Act
through operation of Section 318(c), such imposed duties shall control.

be made on the next succeeding Business Day at such Place of Payment with the
same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity, provided that no additional interest shall

<PAGE>

                                                                              18

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to such Board Resolution and set forth in such Officers' Certificate or in any
such indenture supplemental hereto.

          Except as modified in an Officers' Certificate or supplemental
indenture establishing a series of Securities, the Securities shall be
subordinated in right of payment to Senior Indebtedness as provided in Article
Four.  The Securities of all series shall rank on a parity in right of payment.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Issuer and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

SECTION 3.02.  Denominations.
               -------------

          The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 3.01.  In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

SECTION 3.03.  Execution, Authentication Delivery and Dating.
               ---------------------------------------------

          The Securities shall be executed on behalf of the Issuer by its
Chairman of the Board, its President or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries.  The signature of any of these officers on the Securities
may be manual or facsimile.

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

          At any time and from time to time after the execution and delivery of
this Indenture, the Issuer may deliver Securities of any series executed by the
Issuer to the Trustee for authentication, together with a Issuer Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Issuer Order shall authenticate and deliver such Securities.  In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive and (subject to Section 7.01) shall be fully protected in
relying upon the documents specified in Section 314 of the Trust Indenture Act,
and, in addition:

          (a)  a Board Resolution relating thereto, and if applicable, an
appropriate record of any action taken pursuant to such Board Resolution,
certified by the Secretary or Assistant Secretary of the Issuer;
<PAGE>

                                                                              19

          (b)  an executed supplemental indenture, if any; and

          (c)  an Opinion of Counsel which shall state

          (1)  that the form and terms of such Securities have been established
     by or pursuant to Board Resolutions, by a supplemental indenture or by both
     such resolution or resolutions and such supplemental indenture in
     conformity with the provisions of this Indenture;

          (2)  that the supplemental indenture, if any, when executed and
     delivered by the Issuer, a Guarantor and the Trustee, will constitute a
     valid and legally binding obligation of the Issuer and a Guarantor; and

          (3)  that such Securities, when authenticated and delivered by the
     Trustee and issued by the Issuer in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Issuer, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general equity principles, and will be entitled to
     the benefits of this Indenture.

          If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

SECTION 3.04.  Temporary Securities.
               --------------------

          Pending the preparation of definitive Securities of any series, the
Issuer may execute, and upon Issuer Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
reproduced or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities may determine, as evidenced by their
execution of such Securities.
<PAGE>

                                                                              20

          If temporary Securities of any series are issued, the Issuer will
cause definitive Securities of that series to be prepared without unreasonable
delay.  After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Issuer in a Place of Payment for that
series, without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series, the Issuer shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series.

SECTION 3.05.  Registration, Registration of Transfer and Exchange.
               ---------------------------------------------------

          The Issuer shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Issuer in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Issuer shall provide for the registration
of Securities and of transfers of Securities.  The Trustee is hereby appointed
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided.

          Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the Issuer
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and Stated Maturity.

          At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
an equal aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency.  Whenever any Securities are so surrendered
for exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Issuer, evidencing the same
debt and entitled to the same benefits under this Indenture as the Securities
surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Issuer or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing with such signature
guaranteed by a commercial bank reasonably acceptable to the Trustee or by a
member of a national securities exchange.
<PAGE>

                                                                              21

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuer may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 10.06 or 12.07 not involving any transfer.

          The Issuer shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 12.03 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange of any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 3.06.  Mutilated, Destroyed, Lost and Stolen Securities.
               ------------------------------------------------

          If any mutilated Security is surrendered to the Trustee, the Issuer
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          If there shall be delivered to the Issuer and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Issuer or the Trustee that such Security has been acquired by a bona fide
purchaser, the Issuer shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          If any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Issuer in its discretion may, instead
of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the Issuer
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Issuer, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

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

                                                                              22

SECTION 3.07.  Payment of Interest; Interest Rights Preserved.
               ----------------------------------------------

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

          At the option of the Issuer, interest on the Securities of any series
that bear interest may be paid by mailing a check to the address of the Person
entitled thereto as such address shall appear in the Security Register.

          Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date
("Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Issuer, at its election in each case, as
provided in Clause (1) or (2) below:

          (1)  The Issuer may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner.  The Issuer shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Issuer shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided.  Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment.  The Trustee shall
     promptly notify the Issuer of such Special Record Date and, in the name and
     at the expense of the Issuer, shall cause notice of the proposed payment of
     such Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder of Securities of such series at
     his address as it appears in the Security Register, not less than 10 days
     prior to such Special Record Date.  Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following Clause (2).

          (2)  The Issuer may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may
<PAGE>

                                                                              23

     be required by such exchange, if, after notice given by the Issuer to the
     Trustee of the proposed payment pursuant to this Clause, such manner of
     payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.08.  Persons Deemed Owners.
               ---------------------

          Prior to due presentment of a Security for registration of transfer,
the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.07) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and none of the Issuer, the
Trustee or any agent of the Issuer or the Trustee shall be affected by notice to
the contrary.

SECTION 3.09.  Cancellation.
               ------------

          All Securities surrendered for payment, redemption, conversion,
registration of transfer or exchange or for credit against any sinking fund
payment or analogous obligation shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee and promptly shall be cancelled by it
and, if surrendered to the Trustee, shall be promptly cancelled by it.  The
Issuer may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Securities so delivered promptly
shall be cancelled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture.  All cancelled Securities held
by the Trustee shall be disposed of in accordance with applicable securities
laws.

SECTION 3.10.  Computation of Interest.
               -----------------------

          Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year of twelve 30-day months.

SECTION 4.01. Securities Subordinate to Senior Indebtedness.
              ---------------------------------------------

          The Issuer covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, for the benefit of the
holders, from time to time, of Senior Indebtedness that, to the extent and in
the manner hereinafter set forth in this Article, the Indebtedness represented
by the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made subordinate
and subject in right of payment as provided in this Article to the prior payment
in full in cash or cash equivalents of all Senior Indebtedness; provided,
                                                                --------
however, that the Securities, the Indebtedness represented thereby and the
-------
payment of the principal of (and premium, if any) and interest on the Securities
in all respects shall rank equally with, or prior to, all existing and future
senior subordinated indebtedness (including, without limitation, Indebtedness)
of the Issuer that is subordinated to Senior Indebtedness.

SECTION 4.02. Payment over of Proceeds upon Dissolution, etc.
              ----------------------------------------------

          In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relating to Centennial, the Issuer or any
Guarantor or to their assets, or (b) any liquidation, dissolution or other
winding-up of Centennial, the Issuer or any Guarantor, whether voluntary or
involuntary and whether or not involving insolvency or bankruptcy, or (c) any
assignment for the benefit of creditors or other marshalling of assets or
liabilities of Centennial, the Issuer or any Guarantor (except in connection
with the consolidation or merger of Centennial, the Issuer or any Guarantor or
their liquidation or dissolution following the conveyance, transfer or lease of
all of the properties and assets of the Parent Guarantor substantially as an
entirety upon the terms and conditions described under Article Nine), then and

     payment in full in cash or cash equivalents of all Senior Indebtedness, or
     provision shall be made for such payment in full, before the Holders of
     Securities will be entitled to receive any payment or distribution of any
     kind or character (other than any payment or distribution in the form of
     equity securities or subordinated securities of Centennial, the Issuer or
     any Guarantor or any successor obligor that, in the case of any such
     subordinated securities, are subordinated in right of payment to all Senior
     Indebtedness that may at the time be outstanding to at least the same
     extent as the Securities are so subordinated as provided in this Indenture
     (such equity securities or subordinated securities hereinafter being
     "Permitted Junior Securities") and any payment made pursuant to Article
     Five from monies or U.S. Government Obligations previously deposited with
     the Trustee) on account of principal of, or premium, if any, or interest on

     Junior Securities and any payments made pursuant to Article Five from
     monies or U.S. Government Obligations previously deposited with the

     to the aggregate amounts remaining unpaid on account of the Senior

SECTION 4.03. Suspension of Payment When Designated Senior Indebtedness in
              ------------------------------------------------------------
Default.
-------

          (a) Unless Section 4.02 shall be applicable, upon the occurrence of a
Payment Default, no payment or distribution of any assets of Centennial, the
Issuer or any Guarantor of any kind or character, whether in cash, property or
securities (other than Permitted Junior Securities and payments made pursuant to
Article Five from monies or U.S. Government Obligations previously deposited
with the Trustee), may be made by or on behalf of Centennial, the Issuer or any
Guarantor on account of principal of, premium, if any, or interest on the
Securities or on account of the purchase, redemption or other acquisition of
Securities until such Payment Default shall have been cured or waived in writing
from the Agent Bank or any other representative of a holder of Designated Senior
Indebtedness or shall have ceased to exist or such Designated Senior
Indebtedness shall have been discharged or paid in full in cash or cash
equivalents, after which Centennial, the Issuer or any Guarantor shall resume
making any and all required payments in respect of the Securities, including any
missed payments.

          (b) Unless Section 4.02 shall be applicable, upon (1) the occurrence
of a Non-Payment Default and (2) receipt by the Trustee of written notice
thereof from the Agent Bank or any other representative of a holder of
Designated Senior Indebtedness, then no payment or distribution of any assets of
Centennial, the Issuer or any Guarantor of any kind or character,
<PAGE>

                                                                              26

whether in cash, property or securities (other than Permitted Junior Securities
and payments made pursuant to Article Five from monies or U.S. Government
Obligations previously deposited with the Trustee), may be made by or on behalf
of the Issuer on account of principal of, premium, if any, or interest on the
Securities or on account of the purchase, redemption or other acquisition of
Securities for a period (a "Payment Blockage Period") commencing on the date of
receipt by the Trustee of written notice from the Agent Bank or such other
representative of the holders of Designated Senior Indebtedness in respect of
which the Non-Payment Default exists and shall end on the earliest of (i) 179
days thereafter (provided that any Designated Senior Indebtedness as to which
                 --------
notice was given shall not theretofore have been accelerated, in which case the
provisions of paragraph (a) shall apply), (ii) the date on which such Non-
Payment Default is cured, waived or ceases to exist or such Designated Senior
Indebtedness is discharged or paid in full in cash or cash equivalents or (iii)
the date on which such Payment Blockage Period shall have been terminated by
written notice to the Trustee or the Issuer from the Agent Bank or such other
representative initiating such Payment Blockage Period, after which the Issuer
will resume making any and all required payments in respect of the Securities,
including any missed payments.  In any event, not more than one Payment Blockage
Period may be commenced during any period of 365 consecutive days, and there
must be at least 186 consecutive days in every 365 day period during which there
is no Payment Blockage Period.  No event of default that existed or was
continuing on the date of the commencement of any Payment Blockage Period will
be, or can be made, the basis for the commencement of a subsequent Payment
Blockage Period, unless such default has been cured or waived for a period of
not less than 90 consecutive days subsequent to the commencement of such initial
Payment Blockage Period.

          In the event that, notwithstanding the foregoing and the provisions of
Section 4.02, any payment or distribution shall be made to the Trustee which is
prohibited by the foregoing provisions of this Section and the provisions of
Section 4.02, then and in such event such payment shall be paid over and
delivered forthwith by the Trustee to the Agent Bank and any other
representative of holders of Designated Senior Indebtedness, as their interests
may appear, for application to Designated Senior Indebtedness.

SECTION 4.04. Payment Permitted If No Default.
              -------------------------------

          Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent Centennial, the Issuer or any Guarantor, at
any time except during the pendency of any case, proceeding, dissolution,
liquidation or other winding up, assignment for the benefit of creditors or
other marshalling of assets and liabilities of Centennial, the Issuer or any
Guarantor referred to in Section 4.02 or under the conditions described in
Section 4.03, from making payments at any time of principal of, and premium, if
any, or interest on the Securities.

SECTION 4.05. Subrogation to Rights of Holders of Senior Indebtedness.
              -------------------------------------------------------

          Subject to the payment in full of all Senior Indebtedness, the Holders
of the Securities shall be subrogated (equally and ratably with the holders of
all Pari Passu Indebtedness of Centennial, the Issuer or any Guarantor) to the
rights of the holders of such
<PAGE>

                                                                              27

Senior Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness to the extent that
distributions otherwise payable to the holders of the Securities have been
applied to the payment of Senior Indebtedness. For purposes of such subrogation,
no payments or distributions to the holders of Senior Indebtedness of any cash,
property or securities to which the Holders of the Securities or the Trustee
would be entitled except for the provisions of this Article, and no payments
over pursuant to the provisions of this Article to the holders of Senior
Indebtedness by Holders of the Securities or on their behalf or by the Trustee,
shall, as among Centennial, the Issuer or any Guarantor, its creditors other
than holders of Senior Indebtedness, and the Holders of the Securities, be
deemed to be a payment or distribution by Centennial, the Issuer or any
Guarantor to or on account of the Senior Indebtedness; it being understood that
the provisions of this Article are intended solely for the purpose of
determining the relative rights of the Holders of Securities, on the one hand,
and the holders of Senior Indebtedness, on the other hand.

SECTION 4.06. Provisions Solely to Define Relative Rights.
              -------------------------------------------

          The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders on the one hand and the
holders of Senior Indebtedness on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as between the Issuer and the Holders, the obligation of the
Issuer, which is absolute and unconditional, to pay to the Holders the principal
of, and premium, if any, and interest on the Securities as and when the same
shall become due and payable in accordance with their terms; or (b) affect the
relative rights against the Issuer of the Holders and creditors of the Issuer
other than the holders of Senior Indebtedness; or (c) prevent the Trustee or any
Holder from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
of the holders of Senior Indebtedness.

SECTION 4.07. Trustee to Effectuate Subordination.
              -----------------------------------

          Each Holder of a Security by its acceptance thereof authorizes and
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.

SECTION 4.08. No Waiver of Subordination Provisions.
              -------------------------------------

          (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Issuer or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Issuer with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.
<PAGE>

                                                                              28

          (b) Without in any way limiting the generality of paragraph (a) of
this Section, the holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article or the obligations hereunder of the
Holders to the holders of Senior Indebtedness, do any one or more of the
following:  (1) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding; (2) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (3) release any
Person liable in any manner for the collection of Senior Indebtedness; and (4)
exercise or refrain from exercising any rights against the Issuer and any other
Person.

SECTION 4.09.  Distribution or Notice to Representative.
               ----------------------------------------

          Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness, the distribution may be made and the notice given to their
Representative.

          Upon any payment or distribution of assets of Centennial, the Issuer
or any Guarantor referred to in this Article Four, the Trustee and the Holders
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Indebtedness and
other Indebtedness of Centennial, the Issuer or any Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other acts pertinent thereto or to this Article Four.

SECTION 4.10. Notice to Trustee.
              -----------------

          (a) The Issuer shall give prompt written notice to the Trustee of any
fact known to the Issuer which would prohibit the making of any payment to or by
the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Issuer, the Agent Bank or a holder of Senior Indebtedness or from any trustee,
fiduciary or agent therefor; and, prior to the receipt of any such written
notice, the Trustee, subject to Sections 315(a) through 315(d) of the Trust
Indenture Act, shall be entitled in all respects to assume that no such facts
exist; provided, however, that, if the Trustee shall not have received the
       --------  -------
notice provided for in this Section at least three Business Days prior to the
date upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of, and premium, if
any, or interest on any Security), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it within three Business Days prior to such date.

                                                                              29

          (b) Subject to Sections 315(a) through 315(d) of the Trust Indenture
Act, the Trustee shall be entitled to rely on the delivery to it of a written
notice by a Person representing itself to be a holder of Senior Indebtedness (or
a trustee, fiduciary or agent therefor) to establish that such notice has been
given by a holder of Senior Indebtedness (or a trustee, fiduciary or agent
therefor).  In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

              --------------------------------------------------------------

          Upon any payment or distribution of assets of Centennial, the Issuer
or any Guarantor referred to in this Article, the Trustee, subject to Sections
315(a) through 315(d) of the Trust Indenture Act, and the Holders of the
Securities shall be entitled to rely upon any order or decree entered by any
court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, Custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other indebtedness of Centennial, the Issuer or any
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article;
provided that such court, trustee, receiver, Custodian, assignee, agent or other
--------
Person has been apprized of, or the order, decree or certificate makes reference
to, the provisions of this Article.

Preservation of Trustee's Rights.
--------------------------------

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

SECTION 4.13. Article Applicable to Paying Agents.
              -----------------------------------

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Issuer and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided,
                                                   --------
<PAGE>

                                                                              30

however, that Section 4.12 shall not apply to the Issuer or any Affiliate of the
-------
Issuer if it or such Affiliate acts as Paying Agent.

SECTION 4.14. No Suspension of Remedies.
              -------------------------

          Nothing contained in this Article shall limit the right of the Trustee
or the Holders of Securities to take any action to accelerate the maturity of
the Securities pursuant to Article Six or to pursue any rights or remedies
hereunder or under applicable law, except as provided in Article Six.

SECTION 4.15. Trust Moneys Not Subordinated.
              -----------------------------

          Notwithstanding anything contained herein to the contrary, payments
from cash or the proceeds of Government Securities held in trust under Article
Five hereof by the Trustee (or other qualifying trustee) and which were
deposited in accordance with the terms of Article Four hereof and not in
violation of Section 4.03 hereof for the payment of principal of (and premium,
if any) and interest on the Securities shall not be subordinated to the prior
payment of any Senior Indebtedness or subject to the restrictions set forth in
this Article Four, and none of the Holders shall be obligated to pay over any
such amount to the Issuer or any holder of Senior Indebtedness or any other
creditor of the Issuer.

SECTION 4.16. Trustee Not Fiduciary for Holders of Senior Indebtedness.
              ---------------------------------------------------------

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if
the Trustee shall mistakenly, in the absence of gross negligence or wilful
misconduct, pay over or distribute to Holders of Securities or to the Issuer or
to any other person cash, property or securities to which any holders of Senior
Indebtedness shall be entitled by virtue of this Article or otherwise.  With
respect to the holders of Senior Indebtedness, the Trustee undertakes to perform
or to observe only such of its covenants or obligations as are specifically set
forth in this Article and no implied covenants or obligations with respect to
holders of Senior Indebtedness shall be read into this Indenture against the
Trustee.

     been delivered to the Trustee for cancellation; or

          (B)  all such Securities not theretofore delivered to the Trustee for
     cancellation

               (i)   have become due and payable, or

     on such Securities not theretofore delivered to the Trustee for

     for principal (and premium, if any) and interest to the date of such
     deposit (in the case of Securities which have become due and payable) or to
     the Stated Maturity or Redemption Date, as the case may be;

deposit with the Trustee, in trust for the benefit of the Holders thereof, (i)
funds sufficient to pay, or (ii) U.S. Government Obligations (as defined below)
as will, or will together with the income thereon without consideration of any
reinvestment thereof, be sufficient to pay all sums due for the principal of
(and premium, if any) and interest, if any, on the Securities of such series, as
they shall become due from time to time, and shall pay all costs, charges and
expenses incurred or to be incurred by the Trustee in relation thereto or in
carrying out the provisions of this Indenture, this Indenture shall cease to be
of further effect with respect to Securities of such series (except as to (i)

Person controlled or supervised by and acting as an agency or instrumentality of
the United States of America the timely payment of which is unconditionally
guaranteed as a full faith and credit obligation of the United States of
America, which, in either case under clauses (i) or (ii), are not callable or
redeemable at the option of the issuer thereof, and will also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specified payment of interest on or
principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a depository receipt, provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of interest on or principal of the U.S. Government Obligation evidenced by such
depository receipt.

SECTION 5.03.  Application of Trust Money.
               --------------------------

          Subject to the provisions of the last paragraph of Section 11.03, all
money deposited with the Trustee pursuant to Sections 5.01 and 5.02 shall be
held in trust and applied by it, in accordance with the provisions of the
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Issuer or a Guarantor acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal (and premium, if any) and interest for whose payment such money has
been deposited with the Trustee.

          Any money deposited with the Trustee or any other Paying Agent
remaining unclaimed by the holders of any Securities for two years and eleven
months after the date upon which the principal of or interest on such Securities
shall have become due and payable, shall be repaid to the Issuer by the Trustee
or any such other Paying Agent and such holders shall thereafter be entitled to
look to the Issuer only as general creditors for payment thereof (unless
otherwise provided by law); provided, however, that, before the Trustee or any
                            --------  -------
such other Paying Agent is required to make any such payment to the Issuer, the
Trustee may, upon the request of the Issuer and at the expense of the Issuer,
cause to be published once in an Authorized Newspaper a notice that such money

SECTION 6.02. Acceleration of Maturity; Rescission and Annulment.
              --------------------------------------------------

          If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) of all
of the Securities of that series to be due and payable immediately, by a notice
in writing to the Issuer (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable, anything in this Indenture or in any of the
Securities of such series to the contrary notwithstanding; provided, however,
                                                           --------  -------
that payment of principal of (and premium, if any) and interest on the
Securities of such series shall remain subordinated to the extent provided in
Article Four.

          At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Issuer and the
Trustee, may rescind and annul such declaration and its consequences if

          (1)  the Issuer has paid or deposited with the Trustee a sum
     sufficient to pay

               (A)  all overdue interest on all Securities of that series,

               (B)  the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration and interest thereon at the rate or rates prescribed
          therefor in such Securities,

               (C)  to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

               (D)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

          and

          (2)  all Events of Default with respect to Securities of that series,
     other than the nonpayment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 6.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.
<PAGE>

                                                                              36

SECTION 6.03. Collection of Indebtedness and Suits for Enforcement by Trustee.
              ---------------------------------------------------------------

          The Issuer covenants that if

          (1) default is made in the payment of interest on any Security when
     such interest becomes due and payable and such default continues for a
     period of 30 days,

          (2) default is made in the payment of the principal of (or, premium,
     if any, on) any Security at the Maturity thereof, or

          (3) default is made in the making or satisfaction of any sinking fund
     payment or analogous obligation when the same becomes due pursuant to the
     terms of any Security,

the Issuer, upon demand of the Trustee, will pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal, including any sinking fund payment or analogous
obligations (and premium, if any) and interest, if any, and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal (and premium, if any) and on any overdue interest, at the rate or
rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          If the Issuer fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Issuer or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Issuer or any other obligor upon such Securities, wherever
situated.

          If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

SECTION 6.04. Trustee May File Proofs of Claim.
              --------------------------------

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Issuer or any other obligor upon the
Securities or the property of the Issuer or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Issuer for the payment of overdue
<PAGE>

                                                                              37

principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

          (i)  to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest, if any, owing and unpaid in respect of the
     Securities and to file such other papers or documents and take such other
     actions, including participating as a member, voting or otherwise, of any
     official committee of creditors appointed in such matter, as may be
     necessary or advisable in order to have the claims of the Trustee
     (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding except as aforesaid,
to vote for the election of a trustee in bankruptcy or similar person or to
participate as a member, voting or otherwise, on any committee of creditors.

SECTION 6.05. Trustee May Enforce Claims without Possession of Securities.
              -----------------------------------------------------------

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 6.06. Application of Money Collected.
              ------------------------------

          Subject to the provisions of Article Four, any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium, if

of the payment if only partially paid and upon surrender thereof if fully paid:

          FIRST: To the payment of all amounts due the Trustee under Section
     7.07;

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Securities in
     respect of which or for the benefit of which such money has been collected,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on such Securities for principal (and premium, if
     any) and interest, respectively; and

          THIRD: To the payment of the remainder, if any, to the Issuer, its
     successors or assigns, or to whomever may be so lawfully entitled to
     receive the same, or as a court of competent jurisdiction may direct.

SECTION 6.07. Limitation on Suits.
              -------------------

          No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

          (1)  such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;

          (2)  the Holders of not less than a majority in principal amount of
     the Outstanding Securities of that series shall have made written request
     to the Trustee to institute proceedings in respect of such Event of Default
     in its own name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

              ----------------------------------------------------------------
Interest

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment (subject to the provisions of Article Four) of the principal of
(and premium, if any) and (subject to Section 3.07) interest on such Security on
the Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and the right to institute suit for the
enforcement of any such payment and such rights shall not be impaired without
the consent of such Holder.

SECTION 6.09. Restoration of Rights and Remedies.
              ----------------------------------

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Issuer, a Guarantor, the Trustee and the
Holders shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

SECTION 6.10. Rights and Remedies Cumulative.
              ------------------------------

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 6.11. Delay or Omission Not Waiver.
              ----------------------------

          No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein.  Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 6.12. Control by Holders.
              ------------------

          The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

          (1)  such direction shall not be in conflict with any rule of law or
     with this Indenture,

          (2)  the Trustee shall not determine that the action so directed would
     be unjustly prejudicial to the Holders of the Securities of such series not
     taking part in such direction, or to the Holders of the Securities of any
     other series, and

          (3)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction.

SECTION 6.13.  Waiver of Past Defaults.
               -----------------------

          The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

          (1)  in the payment of the principal of (or premium, if any) or
     interest on any Security of such series, or

          (2)  in respect of a covenant or provision hereof which under Article
     Ten cannot be modified or amended without the consent of the Holder of each
     Outstanding Security of such series affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 6.14.  Undertaking for Costs.
               ---------------------

          All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys= fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security on
or after the Stated Maturity or Maturities expressed in such Security (or, in
the case of redemption, on or after the Redemption Date).

SECTION 6.15. Waiver of Stay or Extension Laws.
              --------------------------------

          The Issuer and Guarantors covenant (to the extent that they may
lawfully do so) that they will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Issuer and
Guarantors (to the extent that they may lawfully do so) hereby expressly waive
all benefit or advantage of any such law and covenants that they will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

                                  THE TRUSTEE

SECTION 7.01. Certain Duties and Responsibilities.
              -----------------------------------

          (a)  Except during the continuance of an Event of Default,

          (1)  the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture, and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (2)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture but need not verify the
     accuracy of the contents thereof or whether procedures specified by or
     pursuant to the provisions of this Indenture have been followed in the
     preparation thereof.

          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

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

                                                                              42

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

          (3)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series, determined as provided in Section 6.12, relating
     to the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Indenture with respect to the Securities of such
     series; and

          (4)  no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

SECTION 7.02. Notice of Defaults.

respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
                                                     --------  -------
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund or analogous obligation installment with respect to Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors or Responsible Officers of the Trustee in good faith determine that
the withholding of such notice is in the interest of the Holders of Securities
of such series; and provided, further, that in the case of any default of the
                    --------  -------
character specified in Section 6.01(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof.  For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

     herein shall be sufficiently evidenced by a Issuer Request or Issuer Order
     and any resolution of the Board of Directors may be sufficiently evidenced
     by a Board Resolution;

          (c)  whenever in the administration of this Indenture the Trustee

     bad faith on its part, rely upon an Officers= Certificate;

     with such request or direction;

          (f)  the Trustee shall not be bound to make any investigation into the

     Guarantor or this Indenture.  Whenever reference is made in this Indenture

     only to an Event of Default of which the Trustee is deemed to have
     knowledge in accordance with this paragraph; and
<PAGE>

                                                                              44

          (i)  the permissive right of the Trustee to take or refrain from
     taking any actions enumerated in this Indenture shall not be construed as a
     duty.

SECTION 7.04. Not Responsible for Recitals or Issuance of Securities.
              ------------------------------------------------------

          The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, shall be taken as the statements of the
Issuer or a Guarantor, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee shall not be
accountable for the use or application by the Issuer or a Guarantor of
Securities or the proceeds thereof.

SECTION 7.05. May Hold Securities.
              -------------------

          The Trustee, any Paying Agent, any Security Registrar or any other
agent of the Issuer or a Guarantor, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 7.08 and

would have if it were not Trustee, Paying Agent, Security Registrar or such
other agent.

SECTION 7.06. Money Held in Trust.
              -------------------

          Money held by the Trustee in trust hereunder need not be segregated

SECTION 7.07. Compensation and Reimbursement.
              ------------------------------

          Each of the Issuer and Guarantors and Centennial agrees (1) to pay to
     the Trustee from time to time reasonable compensation for all services
     rendered by it hereunder (which compensation shall not be limited by any
     provision of law in regard to the compensation of a trustee of an express
     trust);

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

          (3)  to indemnify the Trustee for, and to hold it harmless against,
     any loss, liability or expense incurred without negligence or bad faith on
     its part, arising out of or in connection with the acceptance or
     administration of the trust or trusts hereunder, including the costs and
     expenses, including reasonable attorneys' fees, of defending itself against

<PAGE>

                                                                              45

          As security for the performance of the obligations of the Issuer and
Guarantors and Centennial under this Section the Trustee shall have a lien prior
to the Securities upon all property and funds held or collected by the Trustee,
except funds held in trust for the benefit of the Holders of particular
Securities.

          (1)  When the Trustee incurs expenses or renders services after an
     Event of Default specified in Section 6.01(4) or (5) occurs, the expenses
     and the compensation for the services are intended to constitute expenses
     of administration under any Bankruptcy Law.

          (2)  Each of the Issuer's, the Guarantors' and Centennial's
     obligations under this Section 7.07 and any lien arising hereunder shall
     survive the resignation or removal of the Trustee, the discharge of the
     Issuer's, Guarantors' and Centennial's obligations pursuant to Article VIII
     of this Indenture and any rejection or termination of this Indenture under
     any Bankruptcy Law.

SECTION 7.08. Disqualification; Conflicting Interests.
              ---------------------------------------

          The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act during
the period of time provided for therein. In determining whether the Trustee has
a conflicting interest as defined in Section 310(b) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded this
Indenture with respect to Securities of any particular series of Securities
other than that series. Nothing herein shall prevent the Trustee from filing
with the Commission the application referred to in the second to last paragraph
of Section 310(b) of the Trust Indenture Act.

SECTION 7.09. Corporate Trustee Required; Eligibility.
              ---------------------------------------

          There shall at all times be a corporate Trustee hereunder which
complies with the requirements of Section 310(a) of the Trust Indenture Act,
having a combined capital and surplus of at least $50,000,000, subject to
supervision or examination by federal or state authority and having its
Corporate Trust Office in the Borough of Manhattan, The City of New York.  If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of said supervising or examining authority, then for
the purposes of this Section the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

SECTION 7.10. Resignation and Removal; Appointment of Successor.
              -------------------------------------------------

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 7.11.
<PAGE>

                                                                              46

          (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Issuer.  If the
instrument of acceptance by a successor Trustee required by Section 7.11 shall
not have been delivered to the Trustee within 10 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

          (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Issuer.

          (d) If at any time:

          (1) the Trustee shall fail to comply with Section 7.08(a) after
     written request therefor by the Issuer or by any Holder who has been a bona
     fide Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 7.09 and
     shall fail to resign after written request therefor by the Issuer, a
     Guarantor or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuer or a Guarantor by a Board Resolution may
remove the Trustee with respect to all Securities, or (ii) subject to Section
6.14, any Holder who has been a bona fide Holder of a Security for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee with respect to
all Securities and the appointment of a successor Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Issuer, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 7.11.  If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Issuer and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
7.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Issuer.  If
no successor Trustee with respect to
<PAGE>

                                                                              47

the Securities of any series shall have been so appointed by the Issuer or the
Holders and accepted appointment in the manner required by Section 7.11, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

          (f) The Issuer shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series by mailing
written notice of such event to all Holders of Securities of such series as
their names and addresses appear in the Security Register.  Each notice shall
include the name of the successor Trustee with respect to the Securities of such
series and the address of its Corporate Trust Office.

SECTION 7.11. Acceptance of Appointment by Successor.
              --------------------------------------

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

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Issuer, the
Guarantor, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee,
without any further act,
<PAGE>

                                                                              48

deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates; but, on
request of the Issuer, a Guarantor or any successor Trustee, such retiring
Trustee shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates.

          (c) Upon request of any such successor Trustee, the Issuer shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

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

SECTION 7.12.  Merger, Conversion, Consolidation or Succession to Business.
               -----------------------------------------------------------

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 7.13.  Preferential Collection of Claims Against Issuer.
               ------------------------------------------------

          (a) Subject to subsection (b) of this Section, if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Issuer within three months prior to a default, as defined in subsection (c) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities, as defined in
subsection (c) of this Section:

          (1)  an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal or interest,
     effected after the beginning of such three-month period and valid as
     against the Issuer and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     paragraph (2) of this subsection, or from the exercise of any right of set-
     off which the Trustee could have exercised if a petition in bankruptcy had
     been filed by or against the Issuer upon the date of such default; and
<PAGE>

                                                                              49

          (2)  all property received by the Trustee in respect of any claims as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such three-month
     period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Issuer and its
                  -------  -------
     other creditors, in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

          (A)  to retain for its own account (i) payments made on account of any
     such claim by any Person (other than the Issuer) who is liable thereon, and
     (ii) the proceeds of the bona fide sale of any such claim by the Trustee to
     a third Person, and (iii) distributions made in cash, securities or other
     property in respect of claims filed against the Issuer in bankruptcy or
     receivership or in proceedings for reorganization pursuant to the Federal
     Bankruptcy Act or applicable state law;

          (B)  to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such three-month period;

          (C)  to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such
     three-month period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     subsection (c) of this Section, would occur within three months; or

          (D)  to receive payment on any claim referred to in paragraph (B) or
     (C), against the release of any property held as security for such claim as
     provided in paragraph (B) or (C), as the case may be, to the extent of the
     fair value of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Issuer in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable state law,
<PAGE>

                                                                              50

the same percentage of their respective claims, figured before crediting to the
claim of the Trustee anything on account of the receipt by it from the Issuer of
the funds and property in such special account and before crediting to the
respective claims of the Trustee and the Holders and the holders of other
indenture securities dividends on claims filed against the Issuer in bankruptcy
or receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable state law, but after crediting thereon receipts on
account of the indebtedness represented by their respective claims from all
sources other than from such dividends and from the funds and property so held
in such special account. As used in this paragraph, with respect to any claim,
the term "dividends" shall include any distribution with respect to such claim,
in bankruptcy or receivership or proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable state law, whether such distribution is
made in cash, securities or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such claim. The
court in which such bankruptcy, receivership or proceeding for reorganization is
pending shall have jurisdiction (i) to apportion among the Trustee, the Holders
and the holders of other indenture securities, in accordance with the provisions
of this paragraph, the funds and property held in such special account and
proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to
give to the provisions of this paragraph due consideration in determining the
fairness of the distributions to be made to the Trustee and the Holders and the
holders of other indenture securities with respect to their respective claims,
in which event it shall not be necessary to liquidate or to appraise the value
of any securities or other property held in such special account or as security
for any such claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or otherwise to apply
the provisions of this paragraph as a mathematical formula.

          Any Trustee which has resigned or been removed after the beginning of
such three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this subsection if and only if the
following conditions exist:

          (i)   the receipt of property or reduction of claim, which would have
     given rise to the obligation to account, if such Trustee had continued as
     Trustee, occurred after the beginning of such three-month period; and

          (ii)  such receipt of property or reduction of claim occurred within
     three months after such resignation or removal.

          (b)   There shall be excluded from the operation of subsection (a) of
this Section a creditor relationship arising from:

          (1)  the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;
<PAGE>

                                                                              51

          (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purpose of preserving

SECTION 8.01. Issuer to Furnish Trustee Names and Addresses of Holders.
              --------------------------------------------------------

          The Issuer will furnish or cause to be furnished to the Trustee

          (a)  semi-annually, either (i) not later than June 1 and November 1 in
     each year in the case of Original Issue Discount Securities of any series
     which by their terms do not bear interest prior to Maturity, or (ii) not

     of such series as of the preceding June 1 or November 1 or as of such
     Regular Record Date, as the case may be; and

          (b)  at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Issuer of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

provided, however, that so long as the Trustee is the Security Registrar with
--------  -------
respect to Securities of any series, no such lists need be furnished.

SECTION 8.02. Preservation of Information; Communications to Holders.
              ------------------------------------------------------

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 8.01 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar.  The Trustee may destroy any list furnished to it as provided in
Section 8.01 upon receipt of a new list so furnished.

          (b) If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a
<PAGE>

                                                                              53

Security for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other Holders with respect to their rights under this Indenture
or under the Securities and is accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit to such other
Holders, then the Trustee shall, within five business days after the receipt of
such application, at its election, either

          (i)  afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 8.02(a), or

          (ii) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 8.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 8.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
or would be in violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee
nor any agent of either of them shall be held responsible by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 8.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 8.02(b).

     Outstanding for which it is Trustee on the date of such report;

          Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Issuer shall
so determine, new Securities of any series so modified as to conform, in the

prepared and executed by the Issuer or a Guarantor and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

                                   COVENANTS

SECTION 11.01. Payment of Principal, Premium and Interest.
               ------------------------------------------

          The Issuer covenants and agrees for the benefit of the Holders of
Securities of each series that it will duly and punctually pay the principal of
(and premium, if any) and interest, if any, on the Securities of that series in
accordance with the terms of the Securities of that series and this Indenture.

SECTION 11.02. Maintenance of Office or Agency.
               -------------------------------

          The Issuer will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be
surrendered for registration of transfer and exchange, where notices and demands
to or upon the Issuer in respect of the Securities of that series and this
Indenture may be served and where the Securities may be presented for payment.
The Issuer will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency.  If at any time the Issuer
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

          The Issuer may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
                   --------  -------
shall in any manner relieve the Issuer of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes.  The Issuer will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

                                                                              61

SECTION 11.03. Money for Securities Payments to Be Held in Trust.
               -------------------------------------------------

          If the Issuer shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest, if any, on the Securities of
that series, set aside, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act or of any failure by the Issuer (or by any
other obligor on the Securities of that series) to make any payment of the
principal of (and premium, if any) or interest, if any, on the Securities of
such series when the same shall be due and payable.

          Whenever the Issuer shall have one or more Paying Agents for any
series of Securities, it will, at or prior to the opening of business on each
due date of the principal of (and premium, if any) or interest on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest, if any, so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal
(and premium, if any) or interest, and (unless such Paying Agent is the Trustee)
the Issuer will promptly notify the Trustee of its action or failure so to act.

          If the Issuer shall appoint a Paying Agent other than the Trustee for
any series of Securities, it will cause such Paying Agent to execute and deliver
to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest, if any, on the Securities of that series in
     trust for the benefit of the Persons entitled thereto until such sums shall
     be paid to such Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the Issuer (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest, if any, on the
     Securities of that series; and

          (3)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge with respect to one or more or all series of
Securities hereunder or for any other reason, pay or by Issuer Order direct any
Paying Agent to pay, to the Trustee all sums held in trust for any such series
by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Issuer or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

<PAGE>

                                                                              62

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuer in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Issuer on Issuer Request subject to applicable
abandoned property and escheat law, or (if then held by the Issuer) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Issuer for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuer as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
       --------  -------
required to make any such repayment, may at the expense of the Issuer cause to
be published once a week for two consecutive weeks (in each case on any day of
the week) in an Authorized Newspaper notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Issuer.

SECTION 11.04. Corporate Existence.
               -------------------

          Subject to Article Nine, the Parent Guarantor will do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence.

SECTION 11.05. Payment of Taxes and Other Claims.
               ---------------------------------

          The Parent Guarantor will, and will cause each Restricted Subsidiary

become delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon the Issuer or any Restricted Subsidiary or upon the income, profits
or property of the Issuer or any Restricted Subsidiary, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of the Issuer or any Restricted Subsidiary; provided,
                                                                   --------
however, that neither the Issuer nor any Restricted Subsidiary shall be required
-------
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.

SECTION 11.06. Maintenance of Properties.
               -------------------------

          The Parent Guarantor will cause all its properties used or useful in
the conduct of its business to be maintained and kept in reasonably good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Issuer may
be necessary so that the business carried on in connection therewith may be
properly conducted at all times; provided, however, that nothing in this Section
                                 --------- -------
shall prevent the Issuer from discontinuing the operation or maintenance of any
of its properties if such discontinuance is, in the judgment of the Issuer,
desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders of the Securities of any series.

SECTION 11.07. Waiver of Certain Covenants.
               ---------------------------

<PAGE>

                                                                              63

          The Parent Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 11.04, 11.05 and
11.06, with respect to the Securities of any series, if before the time for such
compliance the Holders of at least 66 2/3% in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Issuer and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

SECTION 11.08. Statement by Officers as to Default.
               -----------------------------------

          The Issuer will, within 90 days after the close of each fiscal year,
commencing with the first fiscal year following the issuance of Securities of
any series under this Indenture, file with the Trustee a certificate of the
principal executive officer, the principal financial officer or the principal
accounting officer of the Issuer, covering the period from the date of issuance
of such Securities to the end of the fiscal year in which such Securities were
issued, in the case of the first such certificate, and covering the preceding
fiscal year in the case of each subsequent certificate, and stating whether or
not, to the knowledge of the signer, the Issuer has complied with all conditions
and covenants on its part contained in this Indenture, and, if the signer has
obtained knowledge of any default by the Issuer in the performance, observance
or fulfillment of any such condition or covenant, specifying each such default
and the nature thereof.  For the purpose of this Section 11.08, compliance shall
be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

               ------------------------

          Securities of any series which are redeemable before their Stated

series) in accordance with this Article.

<PAGE>

                                                                              64

SECTION 12.02. Election to Redeem; Notice to Trustee.
               -------------------------------------

          The election of the Issuer to redeem any Securities shall be evidenced
by a Board Resolution.  In case of any redemption at the election of the Issuer
of less than all the Securities of any series, the Issuer shall, at least 60
days prior to the Redemption Date fixed by the Issuer (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date and of the principal amount of Securities of such series to be redeemed.
In the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Issuer shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 12.03. Selection by Trustee of Securities to Be Redeemed.
               -------------------------------------------------

          If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series; provided, however, that
                                                       --------  -------
Securities of such series registered in the name of the Issuer shall be excluded
from any such selection for redemption until all Securities of such series not
so registered shall have been previously selected for redemption.

          The Trustee shall promptly notify the Issuer in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,

          (2)  the Redemption Price,

<PAGE>

                                                                              65

          (3)  if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5)  that interest, if any, accrued to the date fixed for redemption
     will be paid as specified in said notice,

          (6)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

          (7)  that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of
the Issuer shall be given by the Issuer or, at the Issuer's request, by the
Trustee in the name and at the expense of the Issuer.  No such notice shall be
given at any time when the Issuer or the Trustee shall have received notice that
there exists a default specified in the first paragraph of Section 4.03 or that
such a default will exist at the date fixed for such redemption or as a result
of such redemption.

SECTION 12.05. Deposit of Redemption Price.
               ---------------------------

          Prior to any Redemption Date, the Issuer shall deposit with the
Trustee or with a Paying Agent (or, if the Issuer is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 11.03) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 12.06. Securities Payable on Redemption Date.
               -------------------------------------

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Issuer shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Issuer at the Redemption Price, together with accrued interest to
the Redemption Date, provided, however, that installments of interest whose
                     --------  -------
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 3.07.

<PAGE>

                                                                              66

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

SECTION 12.07. Securities Redeemed in Part.
               ---------------------------

          Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Issuer or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Issuer and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Issuer shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the security so
surrendered.  Securities in denominations larger than $1,000 may be redeemed in
part, but only in whole multiples of $1,000.

SECTION 12.08. Securities No Longer Outstanding After Notice to Trustee and
               ------------------------------------------------------------
Deposit of Cash.
---------------

          If the Issuer, having given notice to the Trustee as provided in
Section 12.02, shall have deposited with the Trustee or a Paying Agent, for the
benefit of the Holders of any Securities of any series or portions thereof
called for redemption in whole or in part cash or other form of payment if
permitted by the terms of such Securities (which amount shall be immediately due
and payable to the Holders of such Securities or portions thereof), in the
amount necessary so to redeem all such Securities or portions thereof on the
Redemption Date and provision satisfactory to the Trustee shall have been made
for the giving of notice of such redemption, such Securities or portions
thereof, shall thereupon, for all purposes of this Indenture, be deemed to be no
longer Outstanding, and the Holders thereof shall be entitled to no rights
thereunder or hereunder, except the right to receive payment of the Redemption
Price, together with interest accrued to the Redemption Date, on or after the
Redemption Date of such Securities or portions thereof.

               -----------------------------------------------------

          The Issuer (1) may deliver Outstanding Securities of a series (other

Securities of a series which have been redeemed either at the election of the
Issuer pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited
        --------
pursuant to the terms of such Securities.  Such Securities shall be received and
credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such sinking fund payment shall be reduced accordingly.

               -----------------------------------------

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Issuer will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 13.02 and will also deliver to the Trustee any Securities to
be so delivered.  Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 12.03 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Issuer in the manner provided in Section 12.04.  Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 12.06 and 12.07.

all or any series to take any action specified in Section 15.01, to be held at
such time and at such place in the Borough of Manhattan, The City of New York,
as the Trustee shall determine.  Notice of every meeting of the Holders of
Securities of all or any series, setting forth the time and place of such
meeting and in general terms the action proposed to be taken at such meeting,

fixed for the meeting.  Failure to receive such notice or any defect therein
shall in no case affect the validity of any action taken at such meeting.  Any
meeting of Holders of Securities of all or any series shall be valid without

Trustee are present in person or by proxy or shall have waived notice thereof
before or after the meeting.

each series that may be affected by the action proposed to be taken at the
meeting shall have requested the Trustee to call a meeting of Holders of
Securities of all series that may be so affected to take any action authorized
in Section 15.01 by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have
mailed or made the first publication of the notice of such meeting within 30
days after receipt of such request, then the Issuer or the Holders in the amount
above specified may determine the time and the place in the Borough of
Manhattan, The City of New York for such meeting and may call such meeting by
mailing or publishing notice thereof as provided in Section 15.02.

representing Securities in an aggregate principal amount sufficient to take
action on the business for the transaction of which such meeting was called
shall be necessary to constitute a quorum.  No business shall be transacted in
the absence of a quorum unless a quorum is represented when the meeting is
called to order.  In the absence of a quorum within 30 minutes of the time
appointed for any such meeting, the meeting shall, if convened at the request of
the Holders of Securities (as provided in Section 15.03), be dissolved.  In any
other case the Persons holding or representing a majority in aggregate principal
amount of the Securities represented at the meeting may adjourn such a meeting
for a period of not less than 10 days with the same effect, for all intents and
purposes, as though a quorum had been present.  In the absence of a quorum at
any such adjourned meeting, such adjourned meeting may be similarly further
adjourned for a period of not less than 10 days.  Notice of the reconvening of
any adjourned meeting shall be given as provided in Section 15.02 except that,
in the case of publication, such notice need be published only once but must be
given not less than five days prior to the date on which the meeting is
scheduled to be reconvened, and in the case of mailing, such notice may be
mailed not less than five days prior to such date.

complying with the provisions of Section 1.04 shall be deemed to be present for
the purposes of determining a quorum and be deemed to have voted; provided,
                                                                  --------
however, that such Holder shall be considered as present or voting only with
-------
respect to the matters covered by such instrument in writing.

          Any resolution passed or decision taken at any meeting of the Holders
of Securities of any series duly held in accordance with this Section shall be

represented at the meeting.

SECTION 15.06. Regulations.
               -----------

Holders of Securities, in regard to proof of the holding of Securities and of
the appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

          The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the Issuer
or by Holders of Securities as provided in Section 15.03, in which case the
Issuer or the Holders of Securities calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman.  A permanent chairman and a
permanent secretary of the meeting shall be elected by vote of the Holders of a
majority in principal amount of the Securities represented at the meeting.

          At any meeting each Holder of a Security of a series entitled to vote
at such meeting, or proxy therefor, shall be entitled to one vote for each
$1,000 principal amount (in the case of Original Issue Discount Securities, such
principal amount to be determined as provided in

the definition of "Outstanding") of Securities of such series held or
represented by him; provided, however, that no vote shall be cast or counted at
                    --------  -------

by the chairman of the meeting to be not Outstanding. The chairman of the
meeting shall have no right to vote except as a Holder of Securities of such
series or proxy therefor. Any meeting of Holders of Securities duly called
pursuant to the provisions of Section 15.02 or 15.03 at which a quorum is
present may be adjourned from time to time, and the meeting may be held as so
adjourned without further notice.

SECTION 15.07. Voting Procedure.
               ----------------

          The vote upon any resolution submitted to any meeting of Holders shall
be by written ballot on which shall be subscribed the signatures of the Holders
of Securities entitled to vote at such meeting, or proxies therefor, and on
which shall be inscribed an identifying number or numbers or to which shall be
attached a list of identifying numbers of the Securities so held or represented
by them.  The permanent chairman of the meeting shall appoint two inspectors of
votes who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting.  A
record in duplicate of the proceedings of each meeting of Holders of Securities
shall be prepared by the secretary of the meeting and there shall be attached to
said record the original reports of the inspectors of votes on any vote by
ballot taken thereat and affidavits by one or more Persons having knowledge of
the facts setting forth a copy of the notice of the meeting and showing that
said notice was mailed or published as provided in Section 15.02 and, if
applicable, Section 15.05.  The record shall be signed and verified by the
permanent chairman and secretary of the meeting and one of the duplicates shall
be delivered to the Issuer and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

          Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

               -----------------------------------

percentage in aggregate principal amount of Securities of any series herein
provided, entitled to vote at any such meeting, evidenced as provided in Section
1.04 and filed with the Trustee, shall be effective in lieu of a meeting of the

SECTION 15.09. No Delay of Rights by Meeting.

conferred hereunder to make such call, any hindrance or delay in the exercise of
any right or rights conferred upon or reserved to the Trustee or the

Holders of Securities of any or all such series under any provisions of this
Indenture or the Securities.

                                ARTICLE SIXTEEN

                            GUARANTEE OF SECURITIES

SECTION 16.01. Guarantee.
               ---------

          Subject to the provisions of this Article Sixteen, each of the
Guarantors hereby, jointly and severally, fully and unconditionally Guarantees
to each Holder of Securities hereunder and to the Trustee on behalf of the
Holders:  (i) the due and punctual payment of the principal of, premium, if any,
on and interest on each Security, when and as the same shall become due and
payable, whether at maturity, by acceleration or otherwise, the due and punctual
payment of interest on the overdue principal of and interest, if any, on the
Securities, to the extent lawful, and the due and punctual performance of all
other obligations of the Issuer to the Holders or the Trustee, all in accordance
with the terms of such Security and this Indenture and (ii) in the case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, that the same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, at Stated Maturity, by
acceleration or otherwise, subject, however, in the case of clauses (i) and (ii)
above, to the limitations set forth in the next succeeding paragraph.

          Each Guarantor and by its acceptance hereof each Holder hereby
confirms that it is the intention of all such parties that the Guarantee by such
Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or
conveyance for purposes of the United States Bankruptcy Code, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
federal or state law.  To effectuate the foregoing intention, the Holders and
such Guarantor hereby irrevocably agree that the obligations of such Guarantor
under its Guarantee shall be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Guarantor and after
giving effect to any collections from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under its
Guarantee or pursuant to the following paragraph, result in the obligations of
such Guarantor under its Guarantee not constituting such fraudulent transfer or
conveyance.

          In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a "Funding Guarantor") under its
Guarantee, such Funding Guarantor shall be entitled to a contribution from all
other Guarantors in a pro rata amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by that Funding Guarantor in discharging the Issuer's
obligations with respect to the Securities or any other Guarantor's obligations
with respect to its Guarantee.  "Adjusted Net Assets" of such Guarantor at any
date shall mean the lesser of the amount by which (x) the fair value of the
property of such Guarantor exceeds the total amount of liabilities, including,
without limitation, contingent liabilities (after giving effect to all other
fixed and contingent liabilities

<PAGE>

                                                                              73

incurred or assumed on such date), but excluding liabilities under the
Guarantee, of such Guarantor at such date and (y) the present fair saleable
value of the assets of such Guarantor at such date exceeds the amount that will
be required to pay the probable liability of such Guarantor on its debts (after
giving effect to all other fixed and contingent liabilities incurred or assumed
on such date and after giving effect to any collection from any Subsidiary of
such Guarantor in respect of the obligations of such Subsidiary under the
Guarantee of such Guarantor), excluding debt in respect of its Guarantee, as
they become absolute and matured.

          Each of the Guarantors hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of merger or bankruptcy of
the Issuer, any right to require a proceeding first against the Issuer, the
benefit of discussion, protest or notice with respect to any such Security or
the debt evidenced thereby and all demands whatsoever (except as specified
above), and covenants that this Guarantee will not be discharged as to any such
Security except by payment in full of the principal thereof and interest thereon
and as provided in Sections 5.01 and 5.02.  In the event of any declaration of
acceleration of such obligations as provided in Article Six, such obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purposes of this Article Sixteen.  In addition, without
limiting the foregoing provisions, upon the effectiveness of an acceleration
under Article Six, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article Sixteen.

          The obligations of each Guarantor under its Guarantee are independent
of the obligations Guaranteed by such Guarantor hereunder, and a separate action
or actions may be brought and prosecuted by the Trustee on behalf of, or by, the
Holders, subject to the terms and conditions set forth in this Indenture,
against a Guarantor to enforce this Guarantee, irrespective of whether any
action is brought against the Issuer or whether the Issuer is joined in any such
action or actions.

          If the Trustee or the Holder is required by any court or otherwise to
return to the Issuer or any Guarantor, or any custodian, receiver, liquidator,
trustee, sequestrator or other similar official acting in relation to the Issuer
or such Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect.  Each of the Guarantors further agrees, to
the fullest extent that it may lawfully do so, that, as between it, on the one
hand, and the Holders and the Trustee, on the other hand, the maturity of the
obligations Guaranteed hereby may be accelerated as provided in Article Six
hereof for the purposes of this Guarantee, notwithstanding any stay, injunction
or other prohibition extant under any applicable bankruptcy law preventing such
acceleration in respect of the obligations Guaranteed hereby.

          Each of the Guarantors hereby irrevocably waives any claim or other
rights which it may now or hereafter acquire against the Issuer or any other
Guarantor that arise from the existence, payment, performance or enforcement of
its obligations under this Guarantee and this Indenture, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, any right to participate in any claim or remedy of the Holders
against the Issuer or any Guarantor or any collateral which any such Holder or
the Trustee on

<PAGE>

                                                                              74

behalf of such Holder hereafter acquires, whether or not such claim, remedy or
right arises in equity, or under contract, statute or common law, including,
without limitation, the right to take or receive from the Issuer or a Guarantor,
directly or indirectly, in cash or other property or by set-off or in any other
manner, payment or security on account of such claim or other rights. If any
amount shall be paid to a Guarantor in violation of the preceding sentence and
the principal of, premium, if any, and accrued interest on the Securities shall
not have been paid in full, such amount shall be deemed to have been paid to
such Guarantor for the benefit of, and held in trust for the benefit of, the
Holders, and shall forthwith be paid to the Trustee for the benefit of the
Holders to be credited and applied upon the principal of, premium, if any, and
accrued interest on the Securities. Each of the Guarantors acknowledges that it
will receive direct and indirect benefits from the issuance of the Securities
pursuant to this Indenture and that the waivers set forth in this Section 16.01
are knowingly made in contemplation of such benefits.

          The Guarantee set forth in this Section 16.01 shall not be valid or
become obligatory for any purpose with respect to a Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

SECTION 16.02. Obligations Unconditional.
               -------------------------

          Nothing contained in this Article Sixteen or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among any
Guarantor and the holders of the Securities, the obligation of such Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the
holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders and creditors of such Guarantor, nor shall anything herein or therein
prevent any Holder or the Trustee on their behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture.

                               ARTICLE SEVENTEEN

SECTION 17.01. Counterparts.

          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

appointed in writing or by the record of the Holders voting in favor thereof at
any meeting of such Holders duly called and held in accordance with the
provisions of Article Fifteen; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or any such record is delivered to the Trustee and, where it is hereby expressly
required, to the Issuer. Such instrument or instruments or such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or voting at
such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and conclusive in favor of the Trustee and the Issuer if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 15.07 and the record so proved

the Trustee and the Issuer, if made in the manner provided in this Section.

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

          (c)  The ownership of Securities shall be proved by the Security
Register.

          (d)  Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Issuer in reliance thereon, whether or not notation of such action is made upon
such Security.

less than 10 days nor more than 60 days prior to the taking of the consent, vote

or Act of the Holders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with,

          (1)  the Trustee by any Holder or by the Issuer shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office and, unless otherwise
     herein expressly provided, any such document shall be deemed to be
     sufficiently made, given, furnished or filed upon its receipt by a
     Responsible Officer of the Trustee, or

          (2)  the Issuer by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Issuer addressed
     to it at the address of its principal office specified in the first
     paragraph of this instrument or at any other address previously furnished
     in writing to the Trustee by the Issuer.

SECTION 1.06. Notice to Holders; Waiver.
              -------------------------

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of principal of (and premium, if any) or interest, if any,
on such Security need not be made at such Place of Payment on such date, but may
be made on the next succeeding Business Day at such Place of Payment with the
same force and effect as if made on the Interest Payment Date or Redemption

                   --------  -------
     or variation of Articles Four, Five, Six, Nine, Eleven, Thirteen and
     Sixteen (and Section 1.01 insofar as it relates to the definition of
     certain terms as used in such Articles) with regard to the Securities of a
     particular series shall not be deemed to constitute a conflict with the
     provisions of those Articles; and

          (15) the Reporting Date of the Securities of the series.

          All Securities of any one series shall be substantially identical

to such Board Resolution and set forth in such Officers' Certificate or in any
such indenture supplemental hereto.

          Except as modified in an Officers' Certificate or supplemental
indenture establishing a series of Securities, the Securities shall be
subordinated in right of payment to Senior Indebtedness as provided in Article
Four. The Securities of all series shall rank on a parity in right of payment.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Issuer and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

SECTION 3.02. Denominations.
              -------------

          The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 3.01. In the absence of
<PAGE>

                                                                              18

any such provisions with respect to the Securities of any series, the Securities
of such series shall be issuable in denominations of $1,000 and any integral
multiple thereof.

SECTION 3.03. Execution, Authentication Delivery and Dating.
              ---------------------------------------------

          The Securities shall be executed on behalf of the Issuer by its
Chairman of the Board, its President or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

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

          At any time and from time to time after the execution and delivery of
this Indenture, the Issuer may deliver Securities of any series executed by the
Issuer to the Trustee for authentication, together with a Issuer Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Issuer Order shall authenticate and deliver such Securities. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive and (subject to Section 7.01) shall be fully protected in
relying upon the documents specified in Section 314 of the Trust Indenture Act,
and, in addition:

          (a)  a Board Resolution relating thereto, and if applicable, an
appropriate record of any action taken pursuant to such Board Resolution,
certified by the Secretary or Assistant Secretary of the Issuer;

          (b)  an executed supplemental indenture, if any; and

          (c)  an Opinion of Counsel which shall state

          (1)  that the form and terms of such Securities have been established
     by or pursuant to Board Resolutions, by a supplemental indenture or by both
     such resolution or resolutions and such supplemental indenture in
     conformity with the provisions of this Indenture;

          (2)  that the supplemental indenture, if any, when executed and
     delivered by the Issuer, a Guarantor and the Trustee, will constitute a
     valid and legally binding obligation of the Issuer and a Guarantor; and

          (3)  that such Securities, when authenticated and delivered by the
     Trustee and issued by the Issuer in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Issuer, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors'
<PAGE>

                                                                              19

     rights and to general equity principles, and will be entitled to the
     benefits of this Indenture.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

SECTION 3.04. Temporary Securities.
              --------------------

          Pending the preparation of definitive Securities of any series, the
Issuer may execute, and upon Issuer Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
reproduced or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities of any series are issued, the Issuer will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Issuer in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Issuer shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series.

SECTION 3.05. Registration, Registration of Transfer and Exchange.
              ---------------------------------------------------

          The Issuer shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Issuer in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Issuer shall provide for the registration
of Securities and of transfers of Securities. The Trustee is hereby appointed
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided.
<PAGE>

                                                                              20

          Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the Issuer
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and Stated Maturity.

          At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
an equal aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Issuer, evidencing the same
debt and entitled to the same benefits under this Indenture as the Securities
surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Issuer or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing with such signature
guaranteed by a commercial bank reasonably acceptable to the Trustee or by a
member of a national securities exchange.

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuer may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 10.06 or 12.07 not involving any transfer.

          The Issuer shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 12.03 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange of any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities.
              ------------------------------------------------

          If any mutilated Security is surrendered to the Trustee, the Issuer
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          If there shall be delivered to the Issuer and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as
<PAGE>

                                                                              21

may be required by them to save each of them and any agent of either of them
harmless, then, in the absence of notice to the Issuer or the Trustee that such
Security has been acquired by a protected purchaser, the Issuer shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

                  If any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Issuer in its discretion may,
instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section, the
Issuer may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Security of any series issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Issuer, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.

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

SECTION 3.07. Payment of Interest; Interest Rights Preserved.
              ----------------------------------------------

                  Interest on any Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.

                  At the option of the Issuer, interest on the Securities of any
series that bear interest may be paid by mailing a check to the address of the
Person entitled thereto as such address shall appear in the Security Register.

                  Any interest on any Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
("Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Issuer, at its election in each case, as
provided in Clause (1) or (2) below:

                  (1) The Issuer may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
<PAGE>

                                                                              22

     Defaulted Interest, which shall be fixed in the following manner. The
     Issuer shall notify the Trustee in writing of the amount of Defaulted
     Interest proposed to be paid on each Security of such series and the date
     of the proposed payment, and at the same time the Issuer shall deposit with
     the Trustee an amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     Clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment. The Trustee shall promptly notify the Issuer of such
     Special Record Date and, in the name and at the expense of the Issuer,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder of Securities of such series at his address as it appears in
     the Security Register, not less than 10 days prior to such Special Record
     Date. Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such Defaulted Interest
     shall be paid to the Persons in whose names the Securities of such series
     (or their respective Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following Clause (2).

          (2)  The Issuer may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     notice given by the Issuer to the Trustee of the proposed payment pursuant
     to this Clause, such manner of payment shall be deemed practicable by the
     Trustee.

          Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.08.  Persons Deemed Owners.
               ---------------------

          Prior to due presentment of a Security for registration of transfer,
the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.07) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and none of the Issuer, the
Trustee or any agent of the Issuer or the Trustee shall be affected by notice to
the contrary.
<PAGE>

                                                                              23

SECTION 3.09.  Cancellation.
               ------------

          All Securities surrendered for payment, redemption, conversion,
registration of transfer or exchange or for credit against any sinking fund
payment or analogous obligation shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee and promptly shall be cancelled by it
and, if surrendered to the Trustee, shall be promptly cancelled by it. The
Issuer may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Securities so delivered promptly
shall be cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of in accordance with the Trustee's normal
procedures unless directed by a Issuer Order.

SECTION 3.10.  Computation of Interest.
               -----------------------

          Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year of twelve 30-day months.

                                 ARTICLE FOUR

                          SUBORDINATION OF SECURITIES

SECTION 4.01.  Securities Subordinate to Senior Indebtedness.
               ---------------------------------------------

          The Issuer covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, for the benefit of the
holders, from time to time, of Senior Indebtedness that, to the extent and in
the manner hereinafter set forth in this Article, the Indebtedness represented
by the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made subordinate
and subject in right of payment as provided in this Article to the prior payment
in full in cash or cash equivalents of all Senior Indebtedness; provided,
however, that the Securities, the Indebtedness represented thereby and the
payment of the principal of (and premium, if any) and interest on the Securities
in all respects shall rank equally with, or prior to, all existing and future
subordinated indebtedness (including, without limitation, Indebtedness) of the
Issuer that is subordinated to Senior Indebtedness.

               ----------------------------------------------

         receive payment in full in cash or cash equivalents of all Senior
         Indebtedness, or provision shall be made for such payment in full,
         before the Holders of Securities will be entitled to receive any
         payment or distribution of any kind or character (other than any
         payment or distribution in the form of equity securities or
         subordinated securities of Centennial, the Issuer or any Guarantor or
         any successor obligor that, in the case of any such subordinated
         securities, are subordinated in right of payment to all Senior
         Indebtedness that may at the time be outstanding to at least the same
         extent as the Securities are so subordinated as provided in this
         Indenture (such equity securities or subordinated securities
         hereinafter being "Permitted Junior Securities") and any payment made
         pursuant to Article Five from monies or U.S. Government Obligations
         previously deposited with the Trustee) on account of principal of, or
         premium, if any, or interest on the Securities;

                  (2) any payment or distribution of assets of Centennial, the
         Issuer or any Guarantor of any kind or character, whether in cash,
         property or securities (other than a payment or distribution in the
         form of Permitted Junior Securities and any payments made pursuant to
         Article Five from monies or U.S. Government Obligations previously
         deposited with the Trustee), by set-off or otherwise, to which the
         Holders of the Securities or the Trustee would be entitled but for the
         provisions of this Indenture shall be paid by the liquidating trustee
         or agent or other Person making such payment or distribution, whether a
         trustee in bankruptcy, a receiver or liquidating trustee or otherwise,
         directly to the holders of Senior Indebtedness or their representative
         or representatives ratably according to the aggregate amounts remaining
         unpaid on account of the Senior Indebtedness to the extent necessary to
         make payment in full of all Senior Indebtedness remaining unpaid, after
         giving effect to any concurrent payment or distribution to the holders
         of such Senior Indebtedness.

Person upon the terms and conditions set forth in Article Nine shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of Centennial,
the Issuer or any Guarantor for the purposes of this Section if the Person
formed by such consolidation or into which Centennial, the Issuer or any
Guarantor is merged or the Person which acquires by conveyance, transfer or
lease such properties and assets substantially as an entirety, as the case may
be, shall, as a part of such consolidation, merger, conveyance, transfer or
lease, comply with the conditions set forth in Article Nine.

SECTION 4.03. Suspension of Payment When Designated Senior Indebtedness in
              ------------------------------------------------------------
Default.
-------

          (a)  Unless Section 4.02 shall be applicable, upon the occurrence of a
Payment Default, no payment or distribution of any assets of Centennial, the
Issuer or any Guarantor of any kind or character, whether in cash, property or
securities (other than Permitted Junior Securities and payments made pursuant to
Article Five from monies or U.S. Government Obligations previously deposited
with the Trustee), may be made by or on behalf of Centennial, the Issuer or any
Guarantor on account of principal of, premium, if any, or interest on the
Securities or on account of the purchase, redemption or other acquisition of
Securities until such Payment Default shall have been cured or waived in writing
from the Agent Bank or any other representative of a holder of Designated Senior
Indebtedness or shall have ceased to exist or such Designated Senior
Indebtedness shall have been discharged or paid in full in cash or cash
equivalents, after which Centennial, the Issuer or any Guarantor shall resume
making any and all required payments in respect of the Securities, including any
missed payments.

          (b)  Unless Section 4.02 shall be applicable, upon (1) the occurrence
of a Non-Payment Default and (2) receipt by the Trustee of written notice
thereof from the Agent Bank or any other representative of a holder of
Designated Senior Indebtedness, then no payment or distribution of any assets of
Centennial, the Issuer or any Guarantor of any kind or character, whether in
cash, property or securities (other than Permitted Junior Securities and
payments made pursuant to Article Five from monies or U.S. Government
Obligations previously deposited with the Trustee), may be made by or on behalf
of the Issuer on account of principal of, premium, if any, or interest on the
Securities or on account of the purchase, redemption or other acquisition of
Securities for a period (a "Payment Blockage Period") commencing on the date of
receipt by the Trustee of written notice from the Agent Bank or such other
representative of the holders of Designated Senior Indebtedness in respect of
which the Non-Payment Default exists and shall end on the earliest of (i) 179
days thereafter (provided that any Designated Senior Indebtedness as to which
notice was given shall not theretofore have been accelerated, in which case the
provisions of paragraph (a) shall apply), (ii) the date on which such Non-
Payment Default is cured, waived or ceases to exist or such Designated Senior
Indebtedness is discharged or paid in full in cash or cash equivalents or (iii)
the date on which such Payment Blockage Period shall have been terminated by
written notice to the Trustee or the Issuer from the Agent Bank or such other
representative initiating such Payment Blockage Period, after which the Issuer
will resume making any and all required payments in respect of the Securities,
including any missed payments. In any event, not more than one Payment Blockage
Period may be commenced during any period of 365 consecutive days, and there
must be at least 186 consecutive days in every 365 day period during which there
is no Payment Blockage Period. No event of default that existed or was
continuing on the date of the commencement of any Payment Blockage Period will
be, or can be made, the basis for the commencement of a subsequent Payment
Blockage Period, unless such default has been cured or waived for a period of
not less than 90 consecutive days subsequent to the commencement of such initial
Payment Blockage Period.

          In the event that, notwithstanding the foregoing and the provisions of
Section 4.02, any payment or distribution shall be made to the Trustee which is
prohibited by the foregoing provisions of this Section and the provisions of
Section 4.02, then and in such event
<PAGE>

                                                                              26

such payment shall be paid over and delivered forthwith by the Trustee to the
Agent Bank and any other representative of holders of Designated Senior
Indebtedness, as their interests may appear, for application to Designated
Senior Indebtedness.

SECTION 4.04.  Payment Permitted If No Default.
               -------------------------------

                  Nothing contained in this Article or elsewhere in this
Indenture or in any of the Securities shall prevent Centennial, the Issuer or
any Guarantor, at any time except during the pendency of any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshalling of assets and liabilities of Centennial, the
Issuer or any Guarantor referred to in Section 4.02 or under the conditions
described in Section 4.03, from making payments at any time of principal of, and
premium, if any, or interest on the Securities.

SECTION 4.05.  Subrogation to Rights of Holders of Senior Indebtedness.
               -------------------------------------------------------

                  Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated (equally and ratably with the
holders of all Pari Passu Indebtedness of Centennial, the Issuer or any
Guarantor) to the rights of the holders of such Senior Indebtedness to receive
payments and distributions of cash, property and securities applicable to the
Senior Indebtedness to the extent that distributions otherwise payable to the
holders of the Securities have been applied to the payment of Senior
Indebtedness. For purposes of such subrogation, no payments or distributions to
the holders of Senior Indebtedness of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article, and no payments over pursuant to the provisions of
this Article to the holders of Senior Indebtedness by Holders of the Securities
or on their behalf or by the Trustee, shall, as among Centennial, the Issuer or
any Guarantor, its creditors other than holders of Senior Indebtedness, and the
Holders of the Securities, be deemed to be a payment or distribution by
Centennial, the Issuer or any Guarantor to or on account of the Senior
Indebtedness; it being understood that the provisions of this Article are
intended solely for the purpose of determining the relative rights of the
Holders of Securities, on the one hand, and the holders of Senior Indebtedness,
on the other hand.

SECTION 4.06.  Provisions Solely to Define Relative Rights.
               -------------------------------------------

                  The provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders on the one hand and
the holders of Senior Indebtedness on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as between the Issuer and the Holders, the obligation of the
Issuer, which is absolute and unconditional, to pay to the Holders the principal
of, and premium, if any, and interest on the Securities as and when the same
shall become due and payable in accordance with their terms; or (b) affect the
relative rights against the Issuer of the Holders and creditors of the Issuer
other than the holders of Senior Indebtedness; or (c) prevent the Trustee or any
Holder from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
of the holders of Senior Indebtedness.

SECTION 4.07.  Trustee to Effectuate Subordination.
               -----------------------------------

                  Each Holder of a Security by its acceptance thereof authorizes
and directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.

SECTION 4.08.  No Waiver of Subordination Provisions.
               --------------------------------------

                  (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Issuer or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Issuer with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                  (b) Without in any way limiting the generality of paragraph
(a) of this Section, the holders of Senior Indebtedness may, at any time and
from time to time, without the consent of or notice to the Trustee or the
Holders, without incurring responsibility to the Holders and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders to the holders of Senior Indebtedness, do any one or
more of the following: (1) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (2) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (3) release any
Person liable in any manner for the collection of Senior Indebtedness; and (4)
exercise or refrain from exercising any rights against the Issuer and any other
Person.

SECTION 4.09.  Distribution or Notice to Representative.
               ----------------------------------------

                  Whenever a distribution is to be made or a notice given to
holders of Senior Indebtedness, the distribution may be made and the notice
given to their Representative.

                  Upon any payment or distribution of assets of Centennial, the
Issuer or any Guarantor referred to in this Article Four, the Trustee and the
Holders shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Indebtedness and
other Indebtedness of Centennial, the Issuer or any Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other acts pertinent thereto or to this Article Four.

SECTION 4.10.  Notice to Trustee.
               -----------------

                  (a) The Issuer shall give prompt written notice to the Trustee
of any fact known to the Issuer which would prohibit the making of any payment
to or by the Trustee in respect of the Securities. Notwithstanding the
provisions of this Article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities, unless and until the Trustee shall have received written notice
thereof from the Issuer, the Agent Bank or a holder of Senior Indebtedness or
from any trustee, fiduciary or agent therefor; and, prior to the receipt of any
such written notice, the Trustee, subject to Sections 315(a) through 315(d) of
the Trust Indenture Act, shall be entitled in all respects to assume that no
such facts exist; provided, however, that, if the Trustee shall not have
received the notice provided for in this Section at least three Business Days
prior to the date upon which by the terms hereof any money may become payable
for any purpose (including, without limitation, the payment of the principal of,
and premium, if any, or interest on any Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it within three Business Days prior to such date.

                  (b) Subject to Sections 315(a) through 315(d) of the Trust
Indenture Act, the Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing itself to be a holder of Senior
Indebtedness (or a trustee, fiduciary or agent therefor) to establish that such
notice has been given by a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor). In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article and, if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

SECTION 4.11.  Reliance on Judicial Order or Certificate of Liquidating Agent.
               --------------------------------------------------------------

                  Upon any payment or distribution of assets of Centennial, the
Issuer or any Guarantor referred to in this Article, the Trustee, subject to
Sections 315(a) through 315(d) of the Trust Indenture Act, and the Holders of
the Securities shall be entitled to rely upon any order or decree entered by any
court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, Custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other indebtedness of Centennial, the Issuer or any
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or
<PAGE>

                                                                              29

to this Article; provided that such court, trustee, receiver, Custodian,
assignee, agent or other Person has been apprized of, or the order, decree or
certificate makes reference to, the provisions of this Article.

SECTION 4.12.  Rights of Trustee as a Holder of Senior Indebtedness;
               -----------------------------------------------------
Preservation of Trustee's Rights.
--------------------------------

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder.

SECTION 4.13.  Article Applicable to Paying Agents.
               -----------------------------------

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Issuer and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that Section 4.12 shall not apply to the Issuer or any Affiliate of the
Issuer if it or such Affiliate acts as Paying Agent.

SECTION 4.14.  No Suspension of Remedies.
               -------------------------

                  Nothing contained in this Article shall limit the right of the
Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Article Six or to pursue any rights or
remedies hereunder or under applicable law, except as provided in Article Six.

SECTION 4.15.  Trust Moneys Not Subordinated.
               -----------------------------

                  Notwithstanding anything contained herein to the contrary,
payments from cash or the proceeds of Government Securities held in trust under
Article Five hereof by the Trustee (or other qualifying trustee) and which were
deposited in accordance with the terms of Article Four hereof and not in
violation of Section 4.03 hereof for the payment of principal of (and premium,
if any) and interest on the Securities shall not be subordinated to the prior
payment of any Senior Indebtedness or subject to the restrictions set forth in
this Article Four, and none of the Holders shall be obligated to pay over any
such amount to the Issuer or any holder of Senior Indebtedness or any other
creditor of the Issuer.

SECTION 4.16.  Trustee Not Fiduciary for Holders of Senior Indebtedness.
               --------------------------------------------------------

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and shall not be liable to any such holders
if the Trustee shall mistakenly, in the absence of gross negligence or wilful
misconduct, pay over or distribute to Holders of Securities or to the Issuer or
to any other person cash, property or securities to which any holders
<PAGE>

                                                                              30

of Senior Indebtedness shall be entitled by virtue of this Article or otherwise.
With respect to the holders of Senior Indebtedness, the Trustee undertakes to
perform or to observe only such of its covenants or obligations as are
specifically set forth in this Article and no implied covenants or obligations
with respect to holders of Senior Indebtedness shall be read into this Indenture
against the Trustee.

SECTION 5.01.  Satisfaction and Discharge of Indenture.
               ---------------------------------------

                  This Indenture shall upon Issuer Request cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, at the
expense of the Issuer, shall execute such instruments as may be requested by the
Issuer acknowledging satisfaction and discharge of this Indenture, when

                  (1)  either

                  (A)  all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 3.06 and
         (ii) Securities for whose payment money has theretofore been deposited
         in trust or segregated and held in trust by the Issuer and thereafter
         repaid to the Issuer or discharged from such trust, as provided in
         Section 11.03) have been delivered to the Trustee for cancellation; or

                  (B)  all such Securities not theretofore delivered to the
         Trustee for cancellation

                           (i)    have become due and payable, or

                           (ii)   will become due and payable at their Stated
         Maturity within one year, or

                           (iii)  are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Issuer, and
the Issuer, in the case of (i), (ii) or (iii) above, has deposited or caused to
be deposited with the Trustee as trust funds in trust for the purpose an amount
sufficient to pay and discharge the entire indebtedness on such Securities not
theretofore delivered to the Trustee for cancellation (other than Securities
which have been destroyed, lost or stolen and which have been replaced or paid
as provided in Section 3.06), for principal (and premium, if any) and interest
to the date of such deposit (in the case of Securities which have become due and
payable) or to the Stated Maturity or Redemption Date, as the case may be;

                                                                              31

                  (2)  the Issuer has paid or caused to be paid all other sums
         payable hereunder by the Issuer; and

                  (3)  the Issuer has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with.

                  Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Issuer to the Trustee under Section 7.07 and,
if money shall have been deposited with the Trustee pursuant to subclause (B) of
Clause (1) of this Section, the obligations of the Trustee under Section 5.03
and the last paragraph of Section 11.03 shall survive.

SECTION 5.02.  Defeasance.
               ----------

                  Provided that the same has been duly authorized with respect
to Securities of a particular series pursuant to Section 3.01(11), if, at any
time after the date hereof, the Issuer shall deposit with the Trustee, in trust
for the benefit of the Holders thereof, (i) funds sufficient to pay, or (ii)
U.S. Government Obligations (as defined below) as will, or will together with
the income thereon without consideration of any reinvestment thereof, be
sufficient to pay all sums due for the principal of (and premium, if any) and
interest, if any, on the Securities of such series, as they shall become due
from time to time, and shall pay all costs, charges and expenses incurred or to
be incurred by the Trustee in relation thereto or in carrying out the provisions
of this Indenture, this Indenture shall cease to be of further effect with
respect to Securities of such series (except as to (i) the Issuer's or a
Guarantor's obligations, as the case may be, with respect to Securities of such
series under Sections 3.05, 3.06 and 11.02, (ii) rights of Holders to receive
payments of the principal of (and premium, if any) and interest, if any, on the
Securities of such series as they shall become due from time to time and other
rights, duties and obligations of Holders as beneficiaries hereof with respect
to the amounts so deposited with the Trustee, and (iii) the rights, obligations
and immunities of the Trustee hereunder (for which purposes the Securities of
such series shall be deemed outstanding)), and the Trustee, on the written
request of the Issuer or a Guarantor, accompanied by the Officer's Certificate
and Opinion of Counsel required by Section 1.02, shall execute and deliver to
the Issuer or a Guarantor such instruments as shall be requisite to evidence the
satisfaction thereof with respect to Securities of such series.

                  As used in this Article Five, "U.S. Government Obligations"
means securities that are (i) direct obligations of the United States of America
for payment of which its full faith and credit is pledged or (ii) obligations of
a Person controlled or supervised by and acting as an agency or instrumentality
of the United States of America the timely payment of which is unconditionally
guaranteed as a full faith and credit obligation of the United States of
America, which, in either case under clauses (i) or (ii), are not callable or
redeemable at the option of the issuer thereof, and will also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specified payment of interest on or
principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a depository receipt, provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government
<PAGE>

                                                                              32

Obligation or the specific payment of interest on or principal of the U.S.
Government Obligation evidenced by such depository receipt.

SECTION 5.03.  Application of Trust Money.
               --------------------------

                  Subject to the provisions of the last paragraph of Section
11.03, all money deposited with the Trustee pursuant to Sections 5.01 and 5.02
shall be held in trust and applied by it, in accordance with the provisions of
the Securities and this Indenture, to the payment, either directly or through
any Paying Agent (including the Issuer or a Guarantor acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal (and premium, if any) and interest for whose payment such money has
been deposited with the Trustee.

SECTION 5.04.  Repayment of Moneys Held by Paying Agent.
               ----------------------------------------

                  Any money deposited with the Trustee or any other Paying Agent
remaining unclaimed by the holders of any Securities for two years and eleven
months after the date upon which the principal of or interest on such Securities
shall have become due and payable, shall be repaid to the Issuer by the Trustee
or any such other Paying Agent and such holders shall thereafter be entitled to
look to the Issuer only as general creditors for payment thereof (unless
otherwise provided by law); provided, however, that, before the Trustee or any
                            --------  -------
such other Paying Agent is required to make any such payment to the Issuer, the
Trustee may, upon the request of the Issuer and at the expense of the Issuer,
cause to be published once in an Authorized Newspaper a notice that such money
remains unclaimed and that, after the date set forth in said notice, the balance
of such money then unclaimed will be returned to the Issuer.

SECTION 5.05.  Reinstatement.
               -------------

                  If the Trustee is unable to apply any money or U.S. Government
Obligations in accordance with Sections 5.01 or 5.02, as the case may be, by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Issuer's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Sections 5.01 or 5.02, as the case may be, until such time as the
Trustee is permitted to apply all such money or U.S. Government Obligations in
accordance with Sections 5.01 or 5.02, as the case may be; provided that, if the
Issuer has made payment of principal of, or interest on any Securities because
of the reinstatement of its obligations, the Issuer shall be subrogated to the
rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee.

         that series when it becomes due and payable, and continuance of such
         default for a period of 30 days (whether or not such default shall be
         by reason of the operation of the provisions of Article Four); or

                  (2) default in the payment of the principal of (or premium, if
         any, on) any Security of that series at its Maturity (whether or not
         such default shall be by reason of the operation of the provisions of

SECTION 6.02.  Acceleration of Maturity; Rescission and Annulment.
               --------------------------------------------------

                  If an Event of Default with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all of the Securities of that series to be due and payable immediately, by a
notice in writing to the Issuer (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) shall
become immediately due and payable, anything in this Indenture or in any of the
Securities of such series to the contrary notwithstanding; provided, however,
                                                           --------  -------
that payment of principal of (and premium, if any) and interest on the
Securities of such series shall remain subordinated to the extent provided in
Article Four.
<PAGE>

                                                                              35

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of that series, by written notice to the
Issuer and the Trustee, may rescind and annul such declaration and its
consequences if

                  (1)  the Issuer has paid or deposited with the Trustee a sum
         sufficient to pay

                           (A) all overdue interest on all Securities of that
                       series,

                           (B) the principal of (and premium, if any, on) any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and interest thereon at
                  the rate or rates prescribed therefor in such Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate or rates
                  prescribed therefor in such Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

                  and

                  (2) all Events of Default with respect to Securities
         of that series, other than the nonpayment of the principal of
         Securities of that series which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 6.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

SECTION 6.03.  Collection of Indebtedness and Suits for Enforcement by Trustee.
               ---------------------------------------------------------------

                  The Issuer covenants that if

                  (1) default is made in the payment of interest on any Security
when such interest becomes due and payable and such default continues for a
period of 30 days,

                  (2) default is made in the payment of the principal of (or,
premium, if any, on) any Security at the Maturity thereof, or

                  (3) default is made in the making or satisfaction of any
sinking fund payment or analogous obligation when the same becomes due pursuant
to the terms of any Security,

the Issuer, upon demand of the Trustee, will pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal, including any sinking fund payment or analogous
obligations (and premium, if any) and interest, if any, and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
<PAGE>

                                                                              36

principal (and premium, if any) and on any overdue interest, at the rate or
rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

                  If the Issuer fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Issuer or any other obligor upon such Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Issuer or any other obligor upon such
Securities, wherever situated.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 6.04.  Trustee May File Proofs of Claim.
               --------------------------------

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Issuer or any other obligor upon the
Securities or the property of the Issuer or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Issuer for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                  (i)  to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest, if any, owing and unpaid
         in respect of the Securities and to file such other papers or documents
         and take such other actions, including participating as a member,
         voting or otherwise, of any official committee of creditors appointed
         in such matter, as may be necessary or advisable in order to have the
         claims of the Trustee (including any claim for the reasonable
         compensation, expenses, disbursements and advances of the Trustee, its
         agents and counsel) and of the Holders allowed in such judicial
         proceeding, and

                  (ii) to collect and receive any moneys or other property
         payable or deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
<PAGE>

                                                                              37

disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding except as
aforesaid, to vote for the election of a trustee in bankruptcy or similar person
or to participate as a member, voting or otherwise, on any committee of
creditors.

SECTION 6.05.  Trustee May Enforce Claims Without Possession of Securities.
               -----------------------------------------------------------

                  All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 6.06.  Application of Money Collected.
               ------------------------------

                  Subject to the provisions of Article Four, any money collected
by the Trustee pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of
such money on account of principal (or premium, if any) or interest, upon
presentation of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee under
         Section 7.07;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in
         respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any) and interest, respectively; and

                  THIRD:  To the payment of the remainder, if any, to the
         Issuer, its successors or assigns, or to whomever may be so lawfully
         entitled to receive the same, or as a court of competent jurisdiction
         may direct.

SECTION 6.07.  Limitation on Suits.
               -------------------
                  No Holder of any Security of any series shall have any right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless
<PAGE>

                                                                              38

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than a majority in principal
         amount of the Outstanding Securities of that series shall have made
         written request to the Trustee to institute proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred
in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 6.08.  Unconditional Right of Holders to Receive Principal, Premium and
               ----------------------------------------------------------------
Interest.
--------

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment (subject to the provisions of Article Four) of
the principal of (and premium, if any) and (subject to Section 3.07) interest on
such Security on the Stated Maturity or Maturities expressed in such Security
(or, in the case of redemption, on the Redemption Date) and the right to
institute suit for the enforcement of any such payment and such rights shall not
be impaired without the consent of such Holder.

SECTION 6.09.  Restoration of Rights and Remedies.
               ----------------------------------

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Issuer, a Guarantor, the Trustee and the
Holders shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

SECTION 6.10.  Rights and Remedies Cumulative.
               ------------------------------

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 3.06, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 6.11.  Delay or Omission Not Waiver.
               ----------------------------

                  No delay or omission of the Trustee or of any Holder to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

SECTION 6.12.  Control by Holders.
               ------------------

                  The Holders of a majority in principal amount of the
Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, with respect
to the Securities of such series, provided that
                                  --------

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture,

                  (2) the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Holders of the Securities
         of such series not taking part in such direction, or to the Holders of
         the Securities of any other series, and

                  (3) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

SECTION 6.13.  Waiver of Past Defaults.
               -----------------------

                  Subject to Section 6.02, the Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Security of such series, or
<PAGE>

                                                                              40

                  (2) in respect of a covenant or provision hereof which under
Article Ten cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

                  Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

SECTION 6.14.  Undertaking for Costs.
               ---------------------

                  All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security on
or after the Stated Maturity or Maturities expressed in such Security (or, in
the case of redemption, on or after the Redemption Date).

SECTION 6.15.  Waiver of Stay or Extension Laws.
               --------------------------------

                  The Issuer and Guarantors covenant (to the extent that they
may lawfully do so) that they will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Issuer and
Guarantors (to the extent that they may lawfully do so) hereby expressly waive
all benefit or advantage of any such law and covenants that they will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture but need not verify the accuracy of the contents thereof or
         whether procedures specified by or pursuant to the provisions of this
         Indenture have been followed in the preparation thereof.

                  (b) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

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

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

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series, determined as provided in Section
         6.12, relating to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee, or exercising any
         trust or power conferred upon the Trustee, under this Indenture with
         respect to the Securities of such series; and

                  (4) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

SECTION 7.02.  Notice of Defaults.
               ------------------

              Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
                                                     --------  -------
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund or analogous obligation instalment with respect to Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors or Responsible Officers of the Trustee in good faith determine that
the withholding of such notice is in the interest of the Holders of Securities
of such series; and provided, further, that in the case of any default of the
                    --------  -------
character specified in Section 6.01(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

SECTION 7.03.  Certain Rights of Trustee.
               -------------------------

          Subject to the provisions of Section 7.01:

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

          (b) any request or direction of the Issuer or a Guarantor mentioned
     herein shall be sufficiently evidenced by a Issuer Request or Issuer Order
     and any resolution of the Board of Directors may be sufficiently evidenced
     by a Board Resolution;

          (c) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (d) the Trustee may consult with counsel and the advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization
     and protection in respect of any action taken, suffered or omitted by it
     hereunder in good faith and in reliance thereon;

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

                                                                              43

          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the Issuer
     or a Guarantor, personally or by agent or attorney;

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

          (h) the Trustee shall not be deemed to have notice or knowledge of any
     matter unless a Responsible Officer assigned to and working in the
     Trustee's corporate trust department has actual knowledge thereof or unless
     written notice thereof is received by the Trustee at the Corporate Trust
     Office and such notice references the Securities generally, the Issuer, a
     Guarantor or this Indenture. Whenever reference is made in this Indenture
     to an Event of Default, such reference shall, insofar as determining any
     liability on the part of the Trustee is concerned, be construed to refer
     only to an Event of Default of which the Trustee is deemed to have
     knowledge in accordance with this paragraph; and

          (i) the permissive right of the Trustee to take or refrain from taking
     any actions enumerated in this Indenture shall not be construed as a duty.

SECTION 7.04.  Not Responsible for Recitals or Issuance of Securities.
               ------------------------------------------------------

          The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, shall be taken as the statements of the
Issuer or a Guarantor, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee shall not be
accountable for the use or application by the Issuer or a Guarantor of
Securities or the proceeds thereof.

SECTION 7.05.  May Hold Securities.
               -------------------

          The Trustee, any Paying Agent, any Security Registrar or any other
agent of the Issuer or a Guarantor, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 7.08 and
7.13, may otherwise deal with the Issuer or a Guarantor with the same rights it
would have if it were not Trustee, Paying Agent, Security Registrar or such
other agent.

                                                                              44

SECTION 7.06.  Money Held in Trust.
               -------------------

          Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder.

SECTION 7.07.  Compensation and Reimbursement.
               ------------------------------

          The Issuer and Guarantors agree (1) to pay to the Trustee from time to
     time reasonable compensation for all services rendered by it hereunder
     (which compensation shall not be limited by any provision of law in regard
     to the compensation of a trustee of an express trust);

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

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses,
     including reasonable attorneys' fees, of defending itself against any claim
     or liability in connection with the exercise or performance of any of its
     powers or duties hereunder.

          As security for the performance of the obligations of the Issuer and
Guarantors under this Section the Trustee shall have a lien prior to the
Securities upon all property and funds held or collected by the Trustee, except
funds held in trust for the benefit of the Holders of particular Securities.

          If the Trustee incurs expenses or renders services after the
occurrence of an Event of Default specified in clause (5) or (6) of Section
6.01, the expenses and the compensation for the services will be intended to
constitute expenses of administration under Bankruptcy Law.

          The provisions of this Section 7.07 shall survive the resignation or
removal of the Trustee and the termination of this Indenture.

SECTION 7.08.  Disqualification; Conflicting Interests.
               ---------------------------------------

          The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act during
the period of time provided for therein. In determining whether the Trustee has
a conflicting interest as defined in Section 310(b) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded this
Indenture with respect to Securities of any particular series of Securities
other than
<PAGE>

                                                                              45

that series. Nothing herein shall prevent the Trustee from filing with the
Commission the application referred to in the second to last paragraph of
Section 310(b) of the Trust Indenture Act.

SECTION 7.09.  Corporate Trustee Required; Eligibility.
               ---------------------------------------

           There shall at all times be a corporate Trustee hereunder which
complies with the requirements of Section 310(a) of the Trust Indenture Act,
having a combined capital and surplus of at least $50,000,000, subject to
supervision or examination by federal or state authority and having its
Corporate Trust Office in the Borough of Manhattan, The City of New York. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of said supervising or examining authority, then for
the purposes of this Section the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

SECTION 7.10.  Resignation and Removal; Appointment of Successor.
               -------------------------------------------------

           (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 7.11.

           (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Issuer. If the
instrument of acceptance by a successor Trustee required by Section 7.11 shall
not have been delivered to the Trustee within 10 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

           (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Issuer.

           (d) If at any time:

           (1) the Trustee shall fail to comply with Section 7.08(a) after
     written request therefor by the Issuer or by any Holder who has been a bona
     fide Holder of a Security for at least six months, or

           (2) the Trustee shall cease to be eligible under Section 7.09
     and shall fail to resign after written request therefor by the Issuer, a
     Guarantor or by any such Holder, or

           (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public
<PAGE>

                                                                              46

         officer shall take charge or control of the Trustee or of its property
         or affairs for the purpose of rehabilitation, conservation or
         liquidation,

then, in any such case, (i) the Issuer or a Guarantor by a Board Resolution may
remove the Trustee with respect to all Securities, or (ii) subject to Section
6.14, any Holder who has been a bona fide Holder of a Security for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee with respect to
all Securities and the appointment of a successor Trustee or Trustees.

            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Issuer, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 7.11. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Issuer and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
7.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Issuer. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Issuer or the Holders and accepted appointment in the
manner required by Section 7.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

            (f) The Issuer shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event to all Holders of Securities of such
series as their names and addresses appear in the Security Register. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 7.11.  Acceptance of Appointment by Successor.
               --------------------------------------

            (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Issuer and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Issuer, a Guarantor or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of
<PAGE>

                                                                              47

the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder.

            (b) In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Issuer,
the Guarantor, the retiring Trustee and each successor Trustee with respect to
the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Issuer, a Guarantor or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Issuer shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

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

SECTION 7.12.  Merger, Conversion, Consolidation or Succession to Business.
               -----------------------------------------------------------

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating
<PAGE>

                                                                              48

Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

SECTION 7.13.  Preferential Collection of Claims Against Issuer.
               ------------------------------------------------

            (a) Subject to subsection (b) of this Section, if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Issuer within three months prior to a default, as defined in subsection (c)
of this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities, as defined in
subsection (c) of this Section:

            (1) an amount equal to any and all reductions in the amount
       due and owing upon any claim as such creditor in respect of principal or
       interest, effected after the beginning of such three-month period and
       valid as against the Issuer and its other creditors, except any such
       reduction resulting from the receipt or disposition of any property
       described in paragraph (2) of this subsection, or from the exercise of
       any right of set-off which the Trustee could have exercised if a petition
       in bankruptcy had been filed by or against the Issuer upon the date of
       such default; and

            (2) all property received by the Trustee in respect of any
       claims as such creditor, either as security therefor, or in satisfaction
       or composition thereof, or otherwise, after the beginning of such three-
       month period, or an amount equal to the proceeds of any such property, if
       disposed of, subject, however, to the rights, if any, of the Issuer and
       its other creditors, in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

            (A) to retain for its own account (i) payments made on account
       of any such claim by any Person (other than the Issuer) who is liable
       thereon, and (ii) the proceeds of the bona fide sale of any such claim by
       the Trustee to a third Person, and (iii) distributions made in cash,
       securities or other property in respect of claims filed against the
       Issuer in bankruptcy or receivership or in proceedings for reorganization
       pursuant to the Federal Bankruptcy Act or applicable State law;

            (B) to realize, for its own account, upon any property held by it as
       security for any such claim, if such property was so held prior to the
       beginning of such three-month period;

            (C) to realize, for its own account, but only to the extent of the
       claim hereinafter mentioned, upon any property held by it as security for
       any such claim, if such claim was created after the beginning of such
       three-month period and such property was received as security therefor
       simultaneously with the creation thereof, and if the Trustee shall
       sustain the burden of proving that at the time such property was so
       received the Trustee had no reasonable cause to believe that a default,
       as defined in subsection (c) of this Section, would occur within three
       months; or
<PAGE>

                                                                              49

            (D) to receive payment on any claim referred to in paragraph (B) or
       (C), against the release of any property held as security for such claim
       as provided in paragraph (B) or (C), as the case may be, to the extent of
       the fair value of such property.

            For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such three-month period for property held as
security at the time of such substitution shall, to the extent of the fair value
of the property released, have the same status as the property released, and, to
the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

            If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Issuer in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee anything on account
of the receipt by it from the Issuer of the funds and property in such special
account and before crediting to the respective claims of the Trustee and the
Holders and the holders of other indenture securities dividends on claims filed
against the Issuer in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
but after crediting thereon receipts on account of the indebtedness represented
by their respective claims from all sources other than from such dividends and
from the funds and property so held in such special account. As used in this
paragraph, with respect to any claim, the term "dividends" shall include any
distribution with respect to such claim, in bankruptcy or receivership or
proceedings for reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, whether such distribution is made in cash, securities or
other property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim. The court in which such bankruptcy,
receivership or proceeding for reorganization is pending shall have jurisdiction
(i) to apportion among the Trustee, the Holders and the holders of other
indenture securities, in accordance with the provisions of this paragraph, the
funds and property held in such special account and proceeds thereof, or (ii) in
lieu of such apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of the
distributions to be made to the Trustee and the Holders and the holders of other
indenture securities with respect to their respective claims, in which event it
shall not be necessary to liquidate or to appraise the value of any securities
or other property held in such special account or as security for any such
claim, or to make a specific allocation of such distributions as between the
secured and unsecured portions of such claims, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

            Any Trustee which has resigned or been removed after the beginning
of such three-month period shall be subject to the provisions of this subsection
as though such resignation or removal had not occurred. If any Trustee has
resigned or been removed prior to

the beginning of such three-month period, it shall be subject to the provisions
of this subsection if and only if the following conditions exist:

                  (i)  the receipt of property or reduction of claim, which
         would have given rise to the obligation to account, if such Trustee had
         continued as Trustee, occurred after the beginning of such three-month
         period; and

                  (ii) such receipt of property or reduction of claim occurred
within three months after such resignation or removal.

                  (b)  There shall be excluded from the operation of subsection
(a) of this Section a creditor relationship arising from:

                  (1)  the ownership or acquisition of securities issued under
         any indenture, or any security or securities having a maturity of one
         year or more at the time of acquisition by the Trustee;

                  (2)  advances authorized by a receivership or bankruptcy court
         of competent jurisdiction or by this Indenture, for the purpose of
         preserving any property which shall at any time be subject to the lien
         of this Indenture or of discharging tax liens or other prior liens or
         encumbrances thereon, if notice of such advances and of the
         circumstances surrounding the making thereof is given to the Holders at
         the time and in the manner provided in this Indenture;

                  (3)  disbursements made in the ordinary course of business in
         the capacity of trustee under an indenture, transfer agent, registrar,
         custodian, paying agent, fiscal agent or depositary, or other similar
         capacity;

                  (4)  an indebtedness created as a result of services rendered
         or premises rented; or an indebtedness created as a result of goods or
         securities sold in a cash transaction, as defined in subsection (c) of
         this Section;

                  (5)  the ownership of stock or of other securities of a
         corporation organized under the provisions of Section 25(a) of the
         Federal Reserve Act, as amended, which is directly or indirectly a
         creditor of the Issuer; and

                  (6)  the acquisition, ownership, acceptance or negotiation of
         any drafts, bills of exchange, acceptances or obligations which fall
         within the classification of self-liquidating paper, as defined in
         subsection (c) of this Section.

                  (c)  For the purposes of this Section only:

         full of the principal of or interest on any of the Securities or upon
         the other indenture securities when and as such principal or interest
         becomes due and payable;

     which the Trustee is also trustee, (ii) which contains provisions
     substantially similar to the provisions of this Section and (iii) under

     possession of or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor

               --------------------------------------------------------

          The Issuer will furnish or cause to be furnished to the Trustee

     which by their terms do not bear interest prior to Maturity, or (ii) not
     more than 15 days after each Regular Record Date in the case of Securities
     of any other series, a list, each in such form as the Trustee may
     reasonably require, of the names and addresses of the Holders of Securities
     of such series as of the preceding June 1 or November 1 or as of such
     Regular Record Date, as the case may be; and
<PAGE>

                                                                              52

          (b)  at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Issuer of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

provided, however, that so long as the Trustee is the Security Registrar with
--------  -------
respect to Securities of any series, no such lists need be furnished.

SECTION 8.02.  Preservation of Information; Communications to Holders.
               ------------------------------------------------------

          (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 8.01 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 8.01 upon receipt of a new list so furnished.

          (b)  If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit to such other Holders, then the Trustee shall, within five business
days after the receipt of such application, at its election, either

          (i)  afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 8.02(a), or

          (ii) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 8.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 8.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so
<PAGE>

                                                                              53

sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

          (c)  Every Holder of Securities, by receiving and holding the same,
agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee
nor any agent of either of them shall be held responsible by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 8.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 8.02(b).

     aggregate not more than 1/2 of 1% of the principal amount of the Securities
     Outstanding for which it is Trustee on the date of such report;

     notice of which has been or is to be withheld by the Trustee in accordance
     with Section 7.02.

          (b)  The Trustee shall transmit by mail to the Holders, as hereinafter
provided, a brief report with respect to the character and amount of any
advances (and if the Trustee elects so to state, the circumstances surrounding
the making thereof) made by the Trustee (as such) since the date of the last
report transmitted pursuant to subsection (a) of this Section (or if no such
report has yet been so transmitted, since the date of execution of this
instrument) for the reimbursement of which it claims or may claim a lien or
charge, prior to that of the Securities, on property or funds held or collected
by it as Trustee and which it has not previously reported pursuant to this

eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders of Securities of such series under this
Indenture; provided, however, that no such supplemental indenture shall, without
           --------  -------
the consent of the Holder of each Outstanding Security affected thereby,

          (1)  change the Stated Maturity of the principal of, or any instalment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of
<PAGE>

                                                                              58

     interest thereon or any premium payable upon the redemption thereof, or
     reduce the amount of the principal of an Original Issue Discount Security
     that would be due and payable upon a declaration of acceleration of the
     Maturity thereof pursuant to Section 6.02, or adversely affect any right of
     repayment at the option of the Holder of any Security, or reduce the amount
     of, or postpone the date fixed for, the payment of any sinking fund or
     analogous obligation, or impair the right to institute suit for the
     enforcement of any such payment on or after the Stated Maturity thereof
     (or, in the case of redemption, on or after the Redemption Date), or

          (2)  reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or

          (3)  modify any of the provisions of this Section, Section 6.13 or
     Section 11.07, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby.

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

SECTION 10.03.  Execution of Supplemental Indentures.
                ------------------------------------

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee in its sole discretion may, but shall not be obligated
to, enter into any such supplemental indenture which adversely affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 10.04.  Effect of Supplemental Indentures.
                ---------------------------------

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.
<PAGE>

                                                                              59

SECTION 10.05.  Conformity with Trust Indenture Act.
                -----------------------------------

          Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 10.06.  Reference in Securities to Supplemental Indentures.
                --------------------------------------------------

          Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Issuer shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Issuer, to any such supplemental indenture may be
prepared and executed by the Issuer or a Guarantor and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

                                ARTICLE ELEVEN

                                   COVENANTS

SECTION 11.01.  Payment of Principal, Premium and Interest.
                ------------------------------------------

          The Issuer covenants and agrees for the benefit of the Holders of
Securities of each series that it will duly and punctually pay the principal of
(and premium, if any) and interest, if any, on the Securities of that series in
accordance with the terms of the Securities of that series and this Indenture.

SECTION 11.02.  Maintenance of Office or Agency.
                -------------------------------

          The Issuer will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be
surrendered for registration of transfer and exchange, where notices and demands
to or upon the Issuer in respect of the Securities of that series and this
Indenture may be served and where the Securities may be presented for payment.
The Issuer will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Issuer
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

          The Issuer may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
                   --------  -------
shall in any manner relieve the Issuer of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
<PAGE>

                                                                              60

purposes. The Issuer will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 11.03.  Money for Securities Payments to Be Held in Trust.
                -------------------------------------------------

          If the Issuer shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest, if any, on the Securities of
that series, set aside, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act or of any failure by the Issuer (or by any
other obligor on the Securities of that series) to make any payment of the
principal of (and premium, if any) or interest, if any, on the Securities of
such series when the same shall be due and payable.

          Whenever the Issuer shall have one or more Paying Agents for any
series of Securities, it will, at or prior to the opening of business on each
due date of the principal of (and premium, if any) or interest on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest, if any, so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal
(and premium, if any) or interest, and (unless such Paying Agent is the Trustee)
the Issuer will promptly notify the Trustee of its action or failure so to act.

          If the Issuer shall appoint a Paying Agent other than the Trustee for
any series of Securities, it will cause such Paying Agent to execute and deliver
to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest, if any, on the Securities of that series in
     trust for the benefit of the Persons entitled thereto until such sums shall
     be paid to such Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the Issuer (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest, if any, on the
     Securities of that series; and

          (3)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge with respect to one or more or all series of
Securities hereunder or for any other reason, pay or by Issuer Order direct any
Paying Agent to pay, to the Trustee all sums held in trust for any such series
by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Issuer or such Paying
Agent; and,
<PAGE>

                                                                              61

upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuer in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Issuer on Issuer Request subject to applicable
abandoned property and escheat law, or (if then held by the Issuer) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Issuer for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuer as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
       --------  -------
required to make any such repayment, may at the expense of the Issuer cause to
be published once a week for two consecutive weeks (in each case on any day of
the week) in an Authorized Newspaper notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Issuer.

SECTION 11.04.  Corporate Existence.
                -------------------

          Subject to Article Nine, the Parent Guarantor will do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence.

SECTION 11.05.  Payment of Taxes and Other Claims.
                ---------------------------------

          The Parent Guarantor will, and will cause each Restricted Subsidiary
to, pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon the Issuer or any Restricted Subsidiary or upon the income, profits
or property of the Issuer or any Restricted Subsidiary, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of the Issuer or any Restricted Subsidiary; provided,
                                                                   --------
however, that neither the Issuer nor any Restricted Subsidiary shall be required
-------
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.

SECTION 11.06.  Maintenance of Properties.
                -------------------------

          The Parent Guarantor will cause all its properties used or useful in
the conduct of its business to be maintained and kept in reasonably good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Issuer may
be necessary so that the business carried on in connection therewith may be
properly conducted at all times; provided, however, that nothing in this Section
                                 --------  -------
shall prevent the Issuer from discontinuing the operation or maintenance of any
of its properties if such discontinuance is, in the judgment of the Issuer,
desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders of the Securities of any series.
<PAGE>

                                                                              62

SECTION 11.07.  Waiver of Certain Covenants.
                ---------------------------

          The Parent Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 11.04, 11.05 and
11.06, with respect to the Securities of any series, if before the time for such
compliance the Holders of at least 66 2/3% in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Issuer and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

SECTION 11.08.  Statement by Officers as to Default.
                -----------------------------------

          The Issuer will, within 90 days after the close of each fiscal year,
commencing with the first fiscal year following the issuance of Securities of
any series under this Indenture, file with the Trustee a certificate of the
principal executive officer, the principal financial officer or the principal
accounting officer of the Issuer, covering the period from the date of issuance
of such Securities to the end of the fiscal year in which such Securities were
issued, in the case of the first such certificate, and covering the preceding
fiscal year in the case of each subsequent certificate, and stating whether or
not, to the knowledge of the signer, the Issuer has complied with all conditions
and covenants on its part contained in this Indenture, and, if the signer has
obtained knowledge of any default by the Issuer in the performance, observance
or fulfillment of any such condition or covenant, specifying each such default
and the nature thereof. For the purpose of this Section 11.08, compliance shall
be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

SECTION 11.09.  Further Assurances.
                ------------------

          From time to time whenever reasonably demanded by the Trustee, the

delivered any and all such further and other instruments and assurances as may
be reasonably necessary or proper to carry out the intention or facilitate the
performance of the terms of this Indenture.

                           REDEMPTION OF SECURITIES

SECTION 12.01.  Applicability of Article.
                ------------------------

          Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.01 for Securities of any
series) in accordance with this Article.
<PAGE>

                                                                              63

SECTION 12.02.  Election to Redeem; Notice to Trustee.
                -------------------------------------

          The election of the Issuer to redeem any Securities shall be evidenced
by a Board Resolution. In case of any redemption at the election of the Issuer
of less than all the Securities of any series, the Issuer shall, at least 60
days prior to the Redemption Date fixed by the Issuer (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date and of the principal amount of Securities of such series to be redeemed. In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Issuer shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 12.03.  Selection by Trustee of Securities to Be Redeemed.
                -------------------------------------------------

          If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series; provided, however, that
                                                       --------  -------
Securities of such series registered in the name of the Issuer shall be excluded
from any such selection for redemption until all Securities of such series not
so registered shall have been previously selected for redemption.

          The Trustee shall promptly notify the Issuer in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 12.04.  Notice of Redemption.
                --------------------

          Notice of redemption shall be given not less than 30 nor more than 60

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,
<PAGE>

                                                                              64

          (3)  if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5)  that interest, if any, accrued to the date fixed for redemption
     will be paid as specified in said notice,

          (6)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

          (7)  that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of
the Issuer shall be given by the Issuer or, at the Issuer's request, by the
Trustee in the name and at the expense of the Issuer. No such notice shall be
given at any time when the Issuer or the Trustee shall have received notice that
there exists a default specified in the first paragraph of Section 4.03 or that
such a default will exist at the date fixed for such redemption or as a result
of such redemption.

SECTION 12.05.  Deposit of Redemption Price.
                ---------------------------

          Prior to any Redemption Date, the Issuer shall deposit with the
Trustee or with a Paying Agent (or, if the Issuer is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 11.03) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 12.06.  Securities Payable on Redemption Date.
                -------------------------------------

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Issuer shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Issuer at the Redemption Price, together with accrued interest to
the Redemption Date, provided, however, that installments of interest whose
                     --------  -------
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 3.07.
<PAGE>

                                                                              65

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

SECTION 12.07.  Securities Redeemed in Part.
                ---------------------------

          Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Issuer or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Issuer and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Issuer shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the security so
surrendered. Securities in denominations larger than $1,000 may be redeemed in
part, but only in whole multiples of $1,000.

SECTION 12.08.  Securities No Longer Outstanding After Notice to Trustee and
                ------------------------------------------------------------
Deposit of Cash.
---------------

          If the Issuer, having given notice to the Trustee as provided in
Section 12.02, shall have deposited with the Trustee or a Paying Agent, for the
benefit of the Holders of any Securities of any series or portions thereof
called for redemption in whole or in part cash or other form of payment if
permitted by the terms of such Securities (which amount shall be immediately due
and payable to the Holders of such Securities or portions thereof), in the
amount necessary so to redeem all such Securities or portions thereof on the
Redemption Date and provision satisfactory to the Trustee shall have been made
for the giving of notice of such redemption, such Securities or portions
thereof, shall thereupon, for all purposes of this Indenture, be deemed to be no
longer Outstanding, and the Holders thereof shall be entitled to no rights
thereunder or hereunder, except the right to receive payment of the Redemption
Price, together with interest accrued to the Redemption Date, on or after the
Redemption Date of such Securities or portions thereof.

                               ARTICLE THIRTEEN

                                 SINKING FUNDS

SECTION 13.01.  Applicability of Article.
                ------------------------

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.01 for Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series
<PAGE>

                                                                              66

is herein referred to as an "optional sinking fund payment." If provided for by
the terms of Securities of any series, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 13.02. Each sinking
fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series.

SECTION 13.02.  Satisfaction of Sinking Fund Payments with Securities.
                -----------------------------------------------------

          The Issuer (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Issuer pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited
        --------
pursuant to the terms of such Securities. Such Securities shall be received and
credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such sinking fund payment shall be reduced accordingly.

SECTION 13.03.  Redemption of Securities for Sinking Fund.
                -----------------------------------------

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Issuer will deliver to the Trustee an Officers'

date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 12.03 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Issuer in the manner provided in Section 12.04. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the

a Holder of one or more Securities of a series affected by the action proposed

meeting is called to order. In the absence of a quorum within 30 minutes of the
time appointed for any such meeting, the meeting shall, if convened at the
request of the Holders of Securities (as provided in Section 15.03), be
dissolved. In any other case the Persons holding or representing a majority in
aggregate principal amount of the Securities represented at the meeting may
adjourn such a meeting for a period of not less than 10 days with the same
effect, for all intents and purposes, as though a quorum had been present. In
the absence of a quorum at any such adjourned meeting, such adjourned meeting
may be similarly further adjourned for a period of not less than 10 days. Notice
of the reconvening of any adjourned meeting shall be given as provided in
Section 15.02 except that, in the case of publication, such notice need be
published only once but must be given not less than five days prior to the date

such notice may be mailed not less than five days prior to such date.

          Any Holder of a Security who has executed an instrument in writing

                                                                  --------
however, that such Holder shall be considered as present or voting only with
-------
respect to the matters covered by such instrument in writing.

          Any resolution passed or decision taken at any meeting of the Holders
of Securities of any series duly held in accordance with this Section shall be
binding on all Holders of such series of Securities whether or not present or
represented at the meeting.

SECTION 15.06.  Regulations.
                -----------

          Notwithstanding any other provisions of this Indenture, the Trustee

Holders of Securities, in regard to proof of the holding of Securities and of
the appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

          The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the Issuer
or by Holders of Securities as provided in Section 15.03, in which case the
Issuer or the Holders of Securities calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman. A permanent chairman and a
permanent secretary of the meeting shall be elected by vote of the Holders of a
majority in principal amount of the Securities represented at the meeting.

          At any meeting each Holder of a Security of a series entitled to vote
at such meeting, or proxy therefor, shall be entitled to one vote for each
$1,000 principal amount (in the case of Original Issue Discount Securities, such
principal amount to be determined as provided in the definition of
"Outstanding") of Securities of such series held or represented by him;
provided, however, that no vote shall be cast or counted at any meeting in
--------  -------
respect of any Security challenged as not Outstanding and ruled by the chairman
of the meeting to be not Outstanding. The chairman of the meeting shall have no
right to vote except as a Holder of Securities of such series or proxy therefor.
Any meeting of Holders of Securities duly called pursuant to the provi-

SECTION 15.07.  Voting Procedure.
                ----------------

          The vote upon any resolution submitted to any meeting of Holders shall
be by written ballot on which shall be subscribed the signatures of the Holders
of Securities entitled to vote at such meeting, or proxies therefor, and on
which shall be inscribed an identifying number or numbers or to which shall be
attached a list of identifying numbers of the Securities so held or represented
by them. The permanent chairman of the meeting shall appoint two inspectors of
votes who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting. A record
in duplicate of the proceedings of each meeting of Holders of Securities shall
be prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more Persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was mailed or published as provided in Section 15.02 and, if applicable,
Section 15.05. The record shall be signed and verified by the permanent chairman
and secretary of the meeting and one of the duplicates shall be delivered to the
Issuer and the other to the Trustee to be preserved by the Trustee, the latter
to have attached thereto the ballots voted at the meeting.

          Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

SECTION 15.08.  Written Consent in Lieu of Meetings.
                -----------------------------------

provided, entitled to vote at any such meeting, evidenced as provided in Section

this Article Fifteen.

SECTION 15.09.  No Delay of Rights by Meeting.
                -----------------------------

          Nothing in this Article contained shall be deemed or construed to
authorize or permit, by reason of any call of a meeting of Holders of Securities
of any or all series or any rights expressly or impliedly conferred hereunder to
make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or the Holders of Securities of any or
all such series under any provisions of this Indenture or the Securities.

                            GUARANTEE OF SECURITIES

SECTION 16.01.  Guarantee.
                ---------

          Subject to the provisions of this Article Sixteen, each of the
Guarantors hereby, jointly and severally, fully and unconditionally Guarantees
to each Holder of Securities hereunder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
on and interest on each Security, when and as the same shall become due and
payable, whether at maturity, by acceleration or otherwise, the due and punctual
payment of interest on the overdue principal of and interest, if any, on the
Securities, to the extent lawful, and the due and punctual performance of all
other obligations of the Issuer to the Holders or the Trustee, all in accordance
with the terms of such Security and this Indenture and (ii) in the case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, that the same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, at Stated Maturity, by
acceleration or otherwise, subject, however, in the case of clauses (i) and (ii)
above, to the limitations set forth in the next succeeding paragraph.

          Each Guarantor and by its acceptance hereof each Holder hereby
confirms that it is the intention of all such parties that the Guarantee by such
Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or
conveyance for purposes of the United States Bankruptcy Code, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
federal or state law. To effectuate the foregoing intention, the Holders and
such Guarantor hereby irrevocably agree that the obligations of such Guarantor
under its Guarantee shall be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Guarantor and after
giving effect to any collections from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under its
Guarantee or pursuant to the following paragraph, result in the obligations of
such Guarantor under its Guarantee not constituting such fraudulent transfer or
conveyance.

          In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a "Funding Guarantor") under its
Guarantee, such Funding Guarantor shall be entitled to a contribution from all
other Guarantors in a pro rata amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by that Funding Guarantor in discharging the Issuer's
obligations with respect to the Securities or any other Guarantor's obligations
with respect to its Guarantee. "Adjusted Net Assets" of such Guarantor at any
date shall mean the lesser of the amount by which (x) the fair value of the
property of such Guarantor exceeds the total amount of liabilities, including,
without limitation, contingent liabilities (after giving effect to all other
fixed and contingent liabilities incurred or assumed on such date), but
excluding liabilities under the Guarantee, of such Guarantor at such date and
(y) the present fair saleable value of the assets of such Guarantor at such date
exceeds the amount that will be required to pay the probable liability of such
Guarantor on its debts (after giving effect to all other fixed and contingent
liabilities incurred or assumed on such date and after giving effect to any
collection from any Subsidiary of such Guarantor in
<PAGE>

                                                                              72

respect of the obligations of such Subsidiary under the Guarantee of such
Guarantor), excluding debt in respect of its Guarantee, as they become absolute
and matured.

          Each of the Guarantors hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of merger or bankruptcy of
the Issuer, any right to require a proceeding first against the Issuer, the
benefit of discussion, protest or notice with respect to any such Security or
the debt evidenced thereby and all demands whatsoever (except as specified
above), and covenants that this Guarantee will not be discharged as to any such
Security except by payment in full of the principal thereof and interest thereon
and as provided in Sections 5.01 and 5.02. In the event of any declaration of
acceleration of such obligations as provided in Article Six, such obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purposes of this Article Sixteen. In addition, without
limiting the foregoing provisions, upon the effectiveness of an acceleration
under Article Six, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article Sixteen.

          The obligations of each Guarantor under its Guarantee are independent
of the obligations Guaranteed by such Guarantor hereunder, and a separate action
or actions may be brought and prosecuted by the Trustee on behalf of, or by, the
Holders, subject to the terms and conditions set forth in this Indenture,
against a Guarantor to enforce this Guarantee, irrespective of whether any
action is brought against the Issuer or whether the Issuer is joined in any such
action or actions.

          If the Trustee or the Holder is required by any court or otherwise to
return to the Issuer or any Guarantor, or any custodian, receiver, liquidator,
trustee, sequestrator or other similar official acting in relation to the Issuer
or such Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each of the Guarantors further agrees, to
the fullest extent that it may lawfully do so, that, as between it, on the one
hand, and the Holders and the Trustee, on the other hand, the maturity of the
obligations Guaranteed hereby may be accelerated as provided in Article Six
hereof for the purposes of this Guarantee, notwithstanding any stay, injunction
or other prohibition extant under any applicable bankruptcy law preventing such
acceleration in respect of the obligations Guaranteed hereby.

          Each of the Guarantors hereby irrevocably waives any claim or other
rights which it may now or hereafter acquire against the Issuer or any other
Guarantor that arise from the existence, payment, performance or enforcement of
its obligations under this Guarantee and this Indenture, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, any right to participate in any claim or remedy of the Holders
against the Issuer or any Guarantor or any collateral which any such Holder or
the Trustee on behalf of such Holder hereafter acquires, whether or not such
claim, remedy or right arises in equity, or under contract, statute or common
law, including, without limitation, the right to take or receive from the Issuer
or a Guarantor, directly or indirectly, in cash or other property or by set-off
or in any other manner, payment or security on account of such claim or other
rights. If any amount shall be paid to a Guarantor in violation of the preceding
sentence and the principal of, premium, if any, and accrued interest on the
Securities shall not have been paid in full, such
<PAGE>

                                                                              73

amount shall be deemed to have been paid to such Guarantor for the benefit of,
and held in trust for the benefit of, the Holders, and shall forthwith be paid
to the Trustee for the benefit of the Holders to be credited and applied upon
the principal of, premium, if any, and accrued interest on the Securities. Each
of the Guarantors acknowledges that it will receive direct and indirect benefits
from the issuance of the Securities pursuant to this Indenture and that the
waivers set forth in this Section 16.01 are knowingly made in contemplation of
such benefits.

          The Guarantee set forth in this Section 16.01 shall not be valid or
become obligatory for any purpose with respect to a Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

SECTION 16.02.  Obligations Unconditional.
                -------------------------

          Nothing contained in this Article Sixteen or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among any
Guarantor and the holders of the Securities, the obligation of such Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the
holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders and creditors of such Guarantor, nor shall anything herein or therein
prevent any Holder or the Trustee on their behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture.

                               ARTICLE SEVENTEEN

          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
