                             SUPPLEMENTAL INDENTURE

                         SUPPLEMENTAL INDENTURE (this "Supplemental Indenture")
                    dated as of February 29, 2000, by and among Centennial
                    Puerto Rico Operations Corp. (the "Guarantor"), an indirect

                    Delaware limited liability company (the "Company"), the

                    National Association, a national banking association (the
                    "Trustee"), as successor to the trustee under the Indenture
                    referred to below.

                                  WITNESSETH:

          WHEREAS the Company and Centennial Communications Corp. (the
"Issuers") have heretofore executed and delivered to the Trustee an Indenture
(the "Indenture") dated as of December 14, 1998, providing for the issuance of
an aggregate principal amount of up to $370,000,000 of 10 3/4% Senior
Subordinated Notes due 2008 (the "Securities");

          WHEREAS Section 9.1 of the Indenture provides that the Guarantor may
execute and deliver to the Trustee a supplemental indenture pursuant to which
the Guarantor shall guarantee all the Issuer's Obligations under the Securities
pursuant to a Guarantee; and

          WHEREAS pursuant to Section 9.1 of the Indenture, the Trustee, the
Issuers and the Guarantor are authorized to execute and deliver this
Supplemental Indenture;

          NOW THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Guarantor, the Issuers and the Trustee mutually covenant and agree for the equal
and ratable benefit of the holders of the Securities as follows:

          1.  Agreement to Guarantee.  Subject to the provisions hereof, the
              ----------------------
Guarantor hereby, jointly and severally with any other future guarantors, fully
and unconditionally Guarantees to each holder of the Securities and to the
Trustee on behalf of the Holders, subject to the terms and conditions of Article
XII of the Indenture: (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 Issuers to the holders or the Trustee,
all in accordance with the terms of such Security and the 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.
<PAGE>

                                                                               2

          The Guarantor 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 convey 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, such Guarantor hereby irrevocably agrees 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
Guarantor and any other future guarantors, the Guarantor agrees, 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 Company'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 respect of the
obligations of such Subsidiary under the Guarantee on such Guarantor), excluding
debt in respect of its Guarantee, as they become absolute and matured.

          The Guarantor hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of merger or bankruptcy of the
Issuers, any right to require a proceeding first against the Issuers, 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 8.1, 8.2 and 8.3 of the Indenture and in "Release of
Guarantee" contained herein.  In the event of any declaration of acceleration of
such Obligations as provided in Article VI of the Indenture, such Obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantor for the purposes of this Guarantee.  In addition, without limiting the
foregoing provisions, upon the effectiveness of an acceleration under Article VI
of the Indenture, the Trustee shall promptly make a demand for payment on the
Securities under this Guarantee as provided herein.

                                                                               3

          The obligations of the 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 Issuers or whether the Issuers are joined in any
such action or actions.

          If the Trustee or the holder is required by any court or otherwise to
return to the Issuers or any Guarantor, or any custodian, receiver, liquidator,
trustee, sequestrator or other similar official acting in relation to Issuers 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.  The Guarantor 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 VI of
the Indenture for the purposes of this Guarantee, notwithstanding any stay,
injunctions or other prohibition extant under any applicable bankruptcy law
preventing such acceleration in respect of the Obligations Guaranteed hereby.

          The Guarantor hereby irrevocably waives any claim or other rights
which it may now or hereafter acquire against the Issuers 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 Issuers 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
Issuers 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. The Guarantor
acknowledges that it will receive direct and indirect benefits from the issuance
of the Securities pursuant to the Indenture and that the waivers set forth in
this Guarantee are knowingly made in contemplating of such benefits.

          Obligations Unconditional.  Nothing contained herein or elsewhere in
          -------------------------
the 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 Issuers, 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
<PAGE>

                                                                               4

Trustee on their behalf from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture.

          Without limiting the foregoing, nothing contained herein will restrict
the right of the Trustee or the holders to take any action to declare the
Guarantee to be due and payable prior to the Stated Maturity of any Securities
pursuant to Section 6.2 of the Indenture or to pursue any rights or remedies
hereunder.

          Release of Guarantee.  The Guarantee issued by the Guarantor will be
          --------------------
automatically and unconditionally released and discharged upon (i) any sale,
exchange or transfer to any Person not an Affiliate of the Issuers of all of the
Capital Stock in, or all or substantially all the assets of, such Guarantor or
the Issuers (ii) the designation of such Guarantor as an Unrestricted
Subsidiary, in each case in compliance with the terms of this Indenture or (iii)
the release by the holders of the indebtedness or guarantee (including any
deemed release upon payment in full of all obligations under such indebtedness
or guarantee), which resulted in the Security being so guaranteed.

          Notice to Trustee.  A Guarantor shall give prompt written notice to
          -----------------
the Trustee of any fact known to such Guarantor which would prohibit the making
of any payment to or by the Trustee in respect of the Guarantee pursuant to the
provisions of this Guarantee.

          This Guarantee Not to Prevent Events of Default.  The failure to make
          -----------------------------------------------
a payment on account of principal of, premium, if any, or interest on the
Securities by reason of any provision of this Guarantee will not be construed as
preventing the occurrence of an Event of Default.

          2.  Ratification of Indenture; Supplemental Indentures Part of
              ----------------------------------------------------------
Indenture.  Except as expressly amended hereby, the Indenture is in all respects
----------
ratified and confirmed and all the terms, conditions and provisions thereof
shall remain in full force and effect.  This Supplemental Indenture shall form a
part of the Indenture for all purposes, and every holder of Securities
heretofore or hereafter authenticated and delivered shall be bound hereby.

          3.  Governing Law.  THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY,
              --------------
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

          4.  Trustee Makes No Representation.  The Trustee makes no
              --------------------------------
representation as to be validity or sufficiency of this Supplemental Indenture.

          5.  Counterparts.  The parties may sign any number of copies of this
              -------------
Supplemental Indenture.  Each signed copy shall be an original, but all of them
together represent the same agreement.

          6.  Effect of headings.  The Section headings herein are for
              -------------------
convenience only and shall not effect the construction thereof.

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
<PAGE>

                                                                              11

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 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.

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.

          (e) The Issuer or the Trustee, as applicable, may set a date for the
purpose of determining the Holders of Securities entitled to consent, vote or
take any other action referred to in this Section 1.04,  which date shall be not

or other action.

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

          Any request, demand, authorization, direction, notice, consent, waiver
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
<PAGE>

                                                                              12

          (2)  the Issuer by the Trustee or by any Holder shall be sufficient

     in writing and mailed, first-class postage prepaid, to the Issuer addressed

     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.

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.

SECTION 1.08.  Effect of Headings and Table of Contents.

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
Date, or at the Stated Maturity, provided that no additional interest shall
accrue with respect to the payment due on such date for the period from and

case may be.

          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.

          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 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,
<PAGE>

                                                                              17

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 to have been
duly adopted by the Board of Directors and to be in full force and effect as of
the date of such certificate, and if the terms and form of the Securities are
established by an Officers' Certificate pursuant to general authorization of the
Board of Directors, such Officers' Certificate;

          (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.
<PAGE>

                                                                              18

          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.

          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
<PAGE>

                                                                              19

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.

          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.
<PAGE>

                                                                              20

          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 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
<PAGE>

                                                                              21

     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.

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
<PAGE>

                                                                              22

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 customary procedures.

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 360-day year consisting of twelve 30-day months.

SECTION 3.11.  CUSIP Numbers.
               -------------

          The Issuer in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
                                           --------
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.  The Issuer will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                                  ARTICLE FOUR

                             [Intentionally Omitted]

                           SATISFACTION AND DISCHARGE

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

                                                                              23

     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,

     cancellation; or

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

               (i) have become due and payable, or

     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

               ----------

          Provided that the same has been duly authorized with respect to

the benefit of the Holders thereof, (i) funds sufficient, in the opinion of a
nationally recognized firm of independent accountants expressed in a written
certification delivered to the Trustee, 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

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

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

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.

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

          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.

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

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.

respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

                                                                              27

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.

          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>

                                                                              28

SECTION 6.3.  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>

                                                                              29

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.
               ------------------------------

          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,

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

          (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 indemnity
     satisfactory to it  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.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 3.07) interest on such Security on the Stated Maturity or Maturities

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

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.

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.

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 and
expenses, 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 person would exercise or use under the circumstances in the conduct of
such person's 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>

                                                                              34

          (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 indemnity satisfactory to it 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:

     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, conclusively rely upon an Officers' Certificate;

          (d)  the Trustee may consult with counsel of its selection 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 security or indemnity satisfactory to it
     against the costs, expenses and liabilities which might be incurred by it
     in compliance with such request or direction;

          (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 at the sole cost of the
     Issuer and shall incur no liability or additional liability of any kind by
     reason of such inquiry or investigation;

          (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
<PAGE>

                                                                              36

     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;

          (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;

          (j)  the Trustee shall not be liable for any action taken, suffered,
     or omitted to be taken by it in good faith and reasonably believed by it to
     be authorized or within the discretion or rights or powers conferred upon
     it by this Indenture;

          (k)  the rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and to each agent, custodian and other
     Person employed to act hereunder; and

          (l)  the Trustee may request that the Issuer deliver an Officers'
     Certificate setting forth the names of individuals and/or titles of
     officers authorized at such time to take specified actions pursuant to this
     Indenture, which Officers' Certificate may be signed by any person
     authorized to sign an Officers' Certificate, including any person specified
     as so authorized in any such certificate previously delivered and not
     superseded.

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.

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.
<PAGE>

                                                                              37

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

          The Issuer and Guarantors agree (1) to pay to the Trustee from time to
     time such compensation as the Issuer, Guarantors and the Trustee shall from
     time to time agree in writing 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 or any predecessor Trustee and their
     agents for, and to hold them harmless against, any and all loss, damage,
     claims, liability or expense, including taxes (other than taxes based upon,
     measured by or determined by the income of the Trustee) 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 (whether asserted by the Issuer,
     Guarantors or any Holder or any other Person) 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.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 6.01, the expenses (including the
reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or other similar 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.
<PAGE>

                                                                              38

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 at the Issuer's expense 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 an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after the giving of such
notice of removal, the Trustee being removed may petition, at the expense of the
Issuer, any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

          (e) 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
<PAGE>

                                                                              39

          (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.

          (f) 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.

          (g) 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,
<PAGE>

                                                                              40

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, 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
<PAGE>

                                                                              41

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

     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
     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

          (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

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 dispose of any list furnished to it as provided in

                                                                              42

          (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) at the
Issuer's expense, 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.

          (b) 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).

SECTION 8.03. Reports by Trustee.

If required by Section 313(a) of the Trust Indenture Act, the Trustee shall,

to Holders a brief report, dated as of such May 15, which complies with the
provisions of such Section 313(a).

          (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
subsection, except that the Trustee shall not be required (but may elect) to
report such advances if such advances remaining unpaid at any time aggregate 10%
or less of the principal amount of the Securities Outstanding for which it is
Trustee at such time, such report to be transmitted within 90 days after such
time.

transmitted by mail:  (i) to all registered Holders, as their names and
addresses appear in the Security Register; (ii) to such Holders of such series
as have, within the two years preceding such transmission, filed their names and
addresses with the Trustee for that purpose; and (iii) except in the case of
reports pursuant to subsection (b) of this Section 8.03, to all Holders of such
series whose names and addresses have been furnished to or received by the
Trustee pursuant to Section 8.01.  A copy of each such report shall, at the time
of such transmission to Holders, be filed by the Trustee with each stock
exchange upon which any Securities are listed, with the Commission and with the
Issuer.  The Issuer will notify the Trustee when any Securities are listed on
any stock exchange.

     is required to file the same with the Commission, copies of the annual
     reports and of the information, documents and other reports (or copies of
     such portions of any of the foregoing as the Commission may from time to
     time by rules and regulations prescribe) which the Parent Guarantor may be
     required to file with the Commission pursuant to Section 13 or Section
     15(d) of the Securities Exchange Act of 1934; or, if the Parent Guarantor
     is not required to file information, documents or reports pursuant to
     either of said Sections, then it shall file with the Trustee and the

     a security listed and registered on a national securities exchange as may
     be prescribed from time to time in such rules and regulations;

          (2)  file with the Trustee and the Commission, in accordance with
     rules and regulations prescribed from time to time by the Commission, such
     additional information, documents and reports with respect to compliance by

     may be required from time to time by such rules and regulations;

          (3)  transmit by mail to all Holders, as their names and addresses
     appear in the Security Register, within 30 days after the filing thereof
     with the Trustee, such summaries of any information, documents and reports
     required to be filed by the Parent Guarantor pursuant to paragraphs (1) and
     (2) of this Section as may be required by rules and regulations prescribed
     from time to time by the Commission; and

          (4)  be deemed to have satisfied the requirements set forth above if
     (a) Centennial prepares, files, mails and supplies reports and other
     documents prepared on a consolidated basis of the types required above, in
     each case within the applicable time periods, and (b) the Parent Guarantor
     is not required to file such reports and other documents separately under
     the applicable rules and regulations of the Commission (after giving effect
     to any exemptive relief) because of the filings made by Centennial.

          Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Issuer's

conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Parent Guarantor under this
Indenture with the same effect as if such successor corporation had been named
as the Parent Guarantor herein, and thereafter, except in the case of a lease,
the predecessor corporation, the Issuer, Centennial and any other Guarantor

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

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

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

                                                                              49

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.

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

     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

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.

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.

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

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

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

          All notices of redemption shall identify the Securities to be redeemed

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (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
<PAGE>

                                                                              54

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

          Prior to 10:00 AM New York City time on 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.

          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

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.

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.

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
        --------

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.

series of Securities, the Issuer will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for

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

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.

          Any Holder of a Security who has executed an instrument in writing
complying with the provisions of Section 1.04 shall be deemed to be present for
the purposes of determining

                                                                              59

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
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
may make such reasonable regulations as it may deem advisable for any meeting of
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 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
<PAGE>

                                                                              60

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.
               -----------------------------------

          The written authorization or consent by the Holders of the requisite
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
Holders of Securities of such series, with respect to any matter provided for in
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.

                                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
<PAGE>

                                                                              61

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 Guarantory") 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 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.
<PAGE>

                                                                              62

          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 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.

                                                                              63

          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

                                 MISCELLANEOUS

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.

          THE BANK OF NEW YORK hereby accepts the trusts in this Indenture
declared and provided, upon the terms and conditions hereinabove set forth.
