      provision shall be deemed to require (whether or not so expressly stated)
      the simultaneous payment of any accrued and unpaid interest to the date of
      payment on such Security payable pursuant to paragraph 1 of the
      Securities.

                                   ARTICLE II
                                 THE SECURITIES

            SECTION 2.1. Form and Dating.

            (a) The Securities and the Trustee's certificate of authentication
in respect thereof shall be substantially in the form of Exhibit A hereto, which
Exhibit is part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Issuers shall
approve the form of the Securities and any notation, legend or endorsement on
them. Any such notations, legends or endorsements not contained in the form of
Security attached as Exhibit A hereto shall be delivered in writing to the
Trustee. Each Security shall be dated the date of its authentication.

            The terms and provisions contained in the forms of Securities shall
constitute, and are hereby expressly made, a part of this Indenture and, to the
extent applicable, the Issuers and the Trustee, by their execution and delivery
of this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

            (b) Securities issued in global form shall be substantially in the
form of Exhibit A-1 or A-2 attached hereto (including the Global Security Legend
thereon and the "Schedule of Exchanges of Interests in the Global Security"
attached thereto). Securities issued in definitive form shall be substantially
in the form of Exhibit A-1 attached hereto (but without the Global Security
Legend thereon and without the "Schedule of Exchanges of Interests in the Global
Security" attached thereto). Each Global Security shall represent such of the
outstanding Securities as shall be specified therein and each shall provide that
it shall represent the aggregate principal amount of outstanding Securities from
time to time endorsed thereon and that the aggregate principal amount of
outstanding Securities represented thereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges and redemptions. Any endorsement
of a Global Security to reflect the amount of any increase or decrease in the
aggregate principal amount of outstanding Securities represented thereby shall
be made by the Trustee in accordance with instructions given by the Holder
thereof as required by Section 2.6 hereof.

            (c) Securities offered and sold in reliance on Regulation S shall be
issued initially in the form of the Regulation S Temporary Global Security,
which shall be deposited on behalf of the purchasers of the Securities
represented thereby with the Trustee, as custodian for The Depository Trust
Company in New York, New York, and registered in the name of the Depositary or
the nominee of the Depositary for the accounts of designated agents holding on
behalf of Euroclear or Clearstream, duly executed by the Issuers and
authenticated by the Trustee as hereinafter provided. The Restricted Period
shall be terminated upon the receipt by the Trustee of (i) a written certificate
from Euroclear and Clearstream certifying that they have

                                       27
<PAGE>
received certification of non-United States beneficial ownership of 100% of the
aggregate principal amount at maturity of the Regulation S Temporary Global
Security (except to the extent of any beneficial owners thereof who acquired an
interest therein during the Restricted Period pursuant to another exemption from
registration under the Securities Act and who shall take delivery of a
beneficial ownership interest in a 144A Global Security bearing a Private
Placement Legend, all as contemplated by (Section 2.6(a)(ii) hereof), and (ii)
an Officers' Certificate from the Issuers. Following the termination of the
Restricted Period, beneficial interests in the Regulation S Temporary Global
Security shall be exchanged for beneficial interests in Regulation S Permanent
Global Securities pursuant to the Applicable Procedures. Simultaneously with the
authentication of Regulation S Permanent Global Securities, the Trustee shall
cancel the Regulation S Temporary Global Security. The aggregate principal
amount of the Regulation S Temporary Global Security and the Regulation S
Permanent Global Securities may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depositary or its
nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

            (d) The provisions of the "Operating Procedures of the Euroclear
System" and "Terms and Conditions Governing Use of Euroclear" and the "General
Terms and Conditions of Cedel Bank" and "Customer Handbook" of Clearstream shall
be applicable to transfers of beneficial interests in the Regulation S Temporary
Global Note and the Regulation S Permanent Global Notes that are held by
Participants through Euroclear or Clearstream.

            SECTION 2.2. Execution and Authentication.

            One Officer shall sign the Securities for each of the Issuers by
manual or facsimile signature.

            If an Officer whose signature is on a Security was an Officer at the
time of such execution but no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless and the
Issuers shall nevertheless be bound by the terms of the Securities and this
Indenture.

            A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security but
such signature shall be conclusive evidence that the Security has been
authenticated pursuant to the terms of this Indenture.

            The Trustee shall authenticate Securities for original issue on the
date of this Indenture an aggregate principal amount of $500,000,000, upon a
Company Order of the Issuers. The written order of the Issuers shall specify the
amount of Securities to be authenticated and the date on which the Securities
are to be authenticated. The aggregate principal amount of Securities
outstanding at any time is unlimited. Upon the written order of the Issuers, the
Trustee shall authenticate Securities in substitution of Securities originally
issued to reflect any name change of either Issuer.

            The Trustee may appoint an authenticating agent acceptable to the
Issuers to authenticate Securities. Unless otherwise provided in the
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to

                                       28
<PAGE>
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Issuers,
any Affiliate of the Issuers, or any of their respective Subsidiaries.

            Securities shall be issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof. Interest shall be
payable in the manner and at the times specified in the form of Securities
attached hereto.

            SECTION 2.3. Registrar and Paying Agent.

            The Issuers shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where Securities may be presented for
registration of transfer or for exchange ("Registrar") and an office or agency
where Securities may be presented for payment ("Paying Agent") and where notices
and demands to or upon the Issuers in respect of the Securities may be served.
The Company may act as Registrar or Paying Agent, except that, for the purposes
of Articles III, VIII, XI and Section 4.14 and as otherwise specified in this
Indenture, neither the Company nor any Affiliate of the Company shall act as
Paying Agent. The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Issuers may have one or more co-Registrars and one or
more additional Paying Agents. The term "Paying Agent" includes any additional
Paying Agent. The Issuers hereby initially appoint the Trustee as Registrar and
Paying Agent, and the Trustee hereby agrees so to act.

            The Issuers may enter into an appropriate written agency agreement
with any Agent not a party to this Indenture, which agreement shall implement
the provisions of this Indenture that relate to such Agent. The Issuers shall
promptly notify the Trustee in writing of the name and address of any such
Agent. If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee
shall act as such.

            The Issuers initially appoint The Depository Trust Company ("DTC")
to act as Depositary with respect to the Global Securities.

            The Issuers initially appoint the Trustee to act as Registrar,
Paying Agent and Securities Custodian with respect to the Global Securities.

            SECTION 2.4. Paying Agent to Hold Assets in Trust.

            The Issuers shall require each Paying Agent other than the Trustee
to agree in writing that each Paying Agent shall hold in trust for the benefit
of the Holders or the Trustee all assets held by the Paying Agent for the
payment of principal of, premium, if any, or interest and Additional Interest,
if any, on, the Securities (whether such assets have been distributed to it by
the Issuers or any other obligor on the Securities), and shall promptly notify
the Trustee in writing of any Default in making any such payment. If either of
the Issuers or a Subsidiary of the Issuers acts as Paying Agent, it shall
segregate such assets and hold them as a separate trust fund for the benefit of
the Holders or the Trustee. The Issuers at any time may require a Paying Agent
to distribute all assets held by it to the Trustee and account for any assets
disbursed and the Trustee may at any time during the continuance of any Payment
Default, upon written request to a Paying Agent, require such Paying Agent to
distribute all assets held by it to the Trustee and to account for any assets
distributed. Upon distribution to the Trustee of all assets

                                       29
<PAGE>
that shall have been delivered by the Issuers to the Paying Agent, the Paying
Agent (if other than the Company) shall have no further liability for such
assets.

            SECTION 2.5. Securityholder Lists.

            The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Issuers shall furnish to the
Trustee on or before the third Business Day preceding each Interest Payment Date
and at such other times as the Trustee may request in writing a list in such
form and as of such date as the Trustee reasonably may require of the names and
addresses of Holders.

            SECTION 2.6. Transfer and Exchange.

            (a) Transfer and Exchange of Global Securities. A Global Security
may not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Securities shall be exchanged by the Company for Definitive Securities if (i)
the Issuers deliver to the Trustee notice from the Depositary that it is
unwilling or unable to continue to act as Depositary or that it is no longer a
clearing agency registered under the Exchange Act and, in either case, a
successor Depositary is not appointed by the Issuers within 90 days after the
date of such notice from the Depositary; (ii) the Issuers in their sole
discretion determines that the Global Securities (in whole but not in part)
should be exchanged for Definitive Securities and delivers a written notice to
such effect to the Trustee; provided that in no event shall the Regulation S
Temporary Global Security be exchanged by the Issuers for Definitive Securities
prior to (x) the expiration of the Restricted Period and (y) the receipt by the
Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under
the Securities Act; or (iii) there shall have occurred and be continuing a
Default or Event of Default with respect to the Securities. Upon the occurrence
of any of the preceding events in (i), (ii) or (iii) above, Definitive
Securities shall be issued in such names as the Depositary shall instruct the
Trustee. Global Securities also may be exchanged or replaced, in whole or in
part, as provided in Sections 2.7 and 2.10 hereof. Every Security authenticated
and delivered in exchange for, or in lieu of, a Global Security or any portion
thereof, pursuant to this Section 2.6 or Section 2.7 or 2.10 hereof, shall be
authenticated and delivered in the form of, and shall be, a Global Security. A
Global Security may not be exchanged for another Security other than as provided
in this Section 2.6(a), however, beneficial interests in a Global Security may
be transferred and exchanged as provided in Section 2.6(b), (c) or (f) hereof.

            (b) Transfer and Exchange of Beneficial Interests in the Global
Securities. The transfer and exchange of beneficial interests in the Global
Securities shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Securities shall be subject to restrictions on transfer
comparable to those set forth herein to the extent required by the Securities
Act. Transfers of beneficial interests in the Global Securities also shall
require compliance with either subparagraph (i) or (ii) below, as applicable, as
well as one or more of the other following subparagraphs, as applicable:

                                       30
<PAGE>
            (i) Transfer of Beneficial Interests in the Same Global Security.
      Beneficial interests in any Restricted Global Security may be transferred
      to Persons who take delivery thereof in the form of a beneficial interest
      in the same Restricted Global Security in accordance with the transfer
      restrictions set forth in the Private Placement Legend; provided, however,
      that prior to the expiration of the Restricted Period, transfers of
      beneficial interests in the Regulation S Temporary Global Security may not
      be made to a U.S. Person or for the account or benefit of a U.S. Person
      (other than an Initial Purchaser). Beneficial interests in any
      Unrestricted Global Security may be transferred to Persons who take
      delivery thereof in the form of a beneficial interest in an Unrestricted
      Global Security. No written orders or instructions shall be required to be
      delivered to the Registrar to effect the transfers described in this
      Section 2.6(b)(i).

            (ii) All Other Transfers and Exchanges of Beneficial Interests in
      Global Securities. In connection with all transfers and exchanges of
      beneficial interests that are not subject to Section 2.6(b)(i) above, the
      transferor of such beneficial interest must deliver to the Registrar
      either (A) (1) a written order from a Participant or an Indirect
      Participant given to the Depositary in accordance with the Applicable
      Procedures directing the Depositary to credit or cause to be credited a
      beneficial interest in another Global Security in an amount equal to the
      beneficial interest to be transferred or exchanged and (2) instructions
      given in accordance with the Applicable Procedures containing information
      regarding the Participant account to be credited with such increase or (B)
      (1) a written order from a Participant or an Indirect Participant given to
      the Depositary in accordance with the Applicable Procedures directing the
      Depositary to cause to be issued a Definitive Security in an amount equal
      to the beneficial interest to be transferred or exchanged and (2)
      instructions given by the Depositary to the Registrar containing
      information regarding the Person in whose name such Definitive Security
      shall be registered to effect the transfer or exchange referred to in
      (A)(1) above; provided that in no event shall Definitive Securities be
      issued upon the transfer or exchange of beneficial interests in the
      Regulation S Temporary Global Security prior to (x) the expiration of the
      Restricted Period and (y) the receipt by the Registrar of any certificates
      required pursuant to Rule 903 under the Securities Act. Upon consummation
      of an Exchange Offer by the Company in accordance with Section 2.6(f)
      hereof, the requirements of this Section 2.6(b)(ii) shall be deemed to
      have been satisfied upon receipt by the Registrar of the instructions
      contained in the Letter of Transmittal delivered by the Holder of such
      beneficial interests in the Restricted Global Securities. Upon
      satisfaction of all of the requirements for transfer or exchange of
      beneficial interests in Global Securities contained in this Indenture and
      the Securities or otherwise applicable under the Securities Act, the
      Trustee shall adjust the principal amount at maturity of the relevant
      Global Securities pursuant to Section 2.6(i) hereof.

            (iii) Transfer of Beneficial Interests to Another Restricted Global
      Security. A beneficial interest in any Restricted Global Security may be
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in another Restricted Global Security if the transfer
      complies with the requirements of Section 2.6(b)(ii) above and the
      Registrar receives the following:

                                       31
<PAGE>
                  (A) if the transferee shall take delivery in the form of a
            beneficial interest in the 144A Global Security, then the transferor
            must deliver a certificate in the form of Exhibit B hereto,
            including the certifications in item (1) thereof; and

                  (B) if the transferee shall take delivery in the form of a
            beneficial interest in the Regulation S Temporary Global Security or
            Regulation S Permanent Global Security, then the transferor must
            deliver a certificate in the form of Exhibit B hereto, including the
            certifications in item (2) thereof.

            (iv) Transfer and Exchange of Beneficial Interests in a Restricted
      Global Security for Beneficial Interests in the Unrestricted Global
      Security. A beneficial interest in any Restricted Global Security may be
      exchanged by any Holder thereof for a beneficial interest in an
      Unrestricted Global Security or transferred to a Person who takes delivery
      thereof in the form of a beneficial interest in an Unrestricted Global
      Security if the exchange or transfer complies with the requirements of

            certifies in the applicable Letter of Transmittal that it is not (1)
            a Participating Broker-Dealer, (2) a Person participating in the

                  beneficial interest to a Person who shall take delivery
                  thereof in the form of a beneficial interest in an
                  Unrestricted Global Security, a certificate from such Holder
                  in the form of Exhibit B hereto, including the certifications
                  in item (4) thereof;

            compliance with the Securities Act.

            If any such transfer is effected pursuant to subparagraph (B) or (D)

            2.11 OF THE INDENTURE AND (IV) THIS GLOBAL SECURITY MAY BE
            TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT
            OF THE COMPANY.

            (iii) Regulation S Temporary Global Security Legend.  The
      Regulation S Temporary Global Security shall bear a legend in
      substantially the following form:

            THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL SECURITY,
            AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR
            DEFINITIVE SECURITIES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED
            HEREIN). NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS
            REGULATION S TEMPORARY GLOBAL SECURITY SHALL BE ENTITLED TO RECEIVE
            PAYMENT OF INTEREST HEREON.

            (h) Cancellation and/or Adjustment of Global Securities. At such
time as all beneficial interests in a particular Global Security have been
exchanged for Definitive Securities or a particular Global Security has been
redeemed, repurchased or canceled in whole and not in part, each such Global
Security shall be returned to or retained and canceled by the Trustee in
accordance with Section 2.11 hereof. At any time prior to such cancellation, if
any beneficial interest in a Global Security is exchanged for or transferred to
a Person who shall take delivery thereof in the form of a beneficial interest in
another Global Security or for Definitive Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
an endorsement shall be made on such Global Security by the Trustee or by the
Depositary at the direction of the Trustee to reflect such reduction; and if the
beneficial interest is being exchanged for or transferred to a Person who shall
take delivery thereof in the form of a beneficial interest in another Global
Security, such other Global Security shall be increased accordingly and an
endorsement shall be made on such Global Security by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

            (i)   General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
            Company shall execute and the Trustee shall authenticate Global
            Securities and Definitive Securities upon the Issuers' order or at
            the Registrar's request.

                  (ii) No service charge shall be made to a Holder of a
            beneficial interest in a Global Security or to a Holder of a
            Definitive Security for any registration of transfer or exchange,
            but the Issuers may require payment of a sum sufficient to cover any
            transfer tax or similar governmental charge payable in connection
            therewith (other than any such transfer taxes or similar
            governmental charge payable upon exchange or transfer).

                  (iii) The Registrar shall not be required to register the
            transfer of or exchange any Security selected for redemption in
            whole or in part, except the unredeemed portion of any Security
            being redeemed in part.

                  (iv) All Global Securities and Definitive Securities issued
            upon any registration of transfer or exchange of Global Securities
            or Definitive Securities shall be the valid and legally binding
            obligations of the Company, evidencing the same debt, and entitled
            to the same benefits under this Indenture, as the Global Securities
            or Definitive Securities surrendered upon such registration of
            transfer or exchange.

                  (v) The Issuers shall not be required (A) to issue, to
            register the transfer of or to exchange any Securities during a
            period beginning at the opening of business 15 days before the day
            of any selection of Securities for redemption under Section 3.3
            hereof and ending at the close of business on the day of selection,
            (B) to register the transfer of or to exchange any Security so
            selected for redemption in whole or in part, except the unredeemed
            portion of any Security being redeemed in part or (C) to register
            the transfer of or to exchange a Security between a record date and
            the next succeeding interest payment date.

                  (vi) Prior to due presentment for the registration of a
            transfer of any Security, the Trustee, any Agent and the Company may
            deem and treat the Person in whose name any Security is registered
            as the absolute owner of such Security for the purpose of receiving
            payment of principal of and interest on such Securities and for all
            other purposes, and none of the Trustee, any Agent or the Company
            shall be affected by notice to the contrary.

                  (vii) The Trustee shall authenticate Global Securities and
            Definitive Securities in accordance with the provisions of Section
            2.2 hereof.

                  (viii) All certifications, certificates and Opinions of
            Counsel required to be submitted to the Registrar pursuant to this
            Section 2.6 to effect a registration of transfer or exchange may be
            submitted by facsimile with the original to follow by first class
            mail.

            SECTION 2.7.      Replacement Securities.

            If a mutilated Security is surrendered to the Trustee or if the
Holder of a Security claims and submits an affidavit or other evidence,
satisfactory to the Trustee, to the Trustee to the effect that the Security has
been lost, destroyed or wrongfully taken, the Issuers shall issue and the
Trustee shall authenticate a replacement Security if the Trustee's requirements
are met. If required by the Trustee or the Issuers, such Holder must provide an
indemnity bond or other indemnity, sufficient in the judgment of both the
Issuers and the Trustee, to protect the Issuers, the Trustee or any Agent from
any loss which any of them may suffer if a Security is replaced. The Issuers may
charge such Holder for its reasonable, out-of-pocket expenses in replacing a
Security.

            Every replacement Security is an additional obligation of the
Issuers.

                                       43
<PAGE>
            SECTION 2.8.      Outstanding Securities.

            Securities outstanding at any time are all the Securities that have
been authenticated by the Trustee (including any Security represented by a
Global Security) except those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee hereunder and those described in this Section 2.8 as not
outstanding. A Security does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Security, except as provided in Section
2.9.

            If a Security is replaced pursuant to Section 2.7 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser. A mutilated Security ceases to be outstanding
upon surrender of such Security and replacement thereof pursuant to Section 2.7.

            If on a Redemption Date or the Maturity Date the Paying Agent (other
than the Issuers or an Affiliate of the Issuers) holds cash sufficient to pay
all of the principal and interest due on the Securities payable on that date and
payment of the Securities called for redemption or payable on such Maturity Date
is not otherwise prohibited pursuant to this Indenture, then on and after that
date such Securities cease to be outstanding and interest on them ceases to
accrue.

            SECTION 2.9.      Treasury Securities.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, amendment, supplement, waiver or
consent, Securities owned by the Issuers or Affiliates of the Issuers shall be
disregarded, except that, for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, amendment, supplement,
waiver or consent, only Securities that the Trustee knows are so owned shall be
disregarded.

            SECTION 2.10.     Temporary Securities.

            Until definitive Securities are ready for delivery, the Issuers may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Issuers reasonably and in good faith consider
appropriate for temporary Securities. Without unreasonable delay, the Issuers
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities. Until so exchanged, the temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as
permanent Securities authenticated and delivered hereunder.

            SECTION 2.11.     Cancellation.

            The Issuers at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Issuers or an Affiliate of the Issuers), and no one else, shall
cancel and, at the written direction of the Issuers, shall dispose of all
Securities

                                       44
<PAGE>
surrendered for transfer, exchange, payment or cancellation. Subject to Section
2.7, the Issuers may not issue new Securities to replace Securities that have
been paid or delivered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section 2.11, except as expressly permitted in the form of Securities
and as permitted by this Indenture.

            SECTION 2.12.     Defaulted Interest.

            Interest or Additional Interest, if any, 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 Record Date
for such interest.

            Any interest or Additional Interest, if any, on any Security which
is payable, but is not punctually paid or duly provided for, on any Interest
Payment Date plus, to the extent lawful, any interest or Additional Interest, if
any, payable on the defaulted interest (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered holder on the relevant
Record Date, and such Defaulted Interest may be paid by the Issuers, at their
election in each case, as provided in clause (1) or (2) below:

            (1) The Issuers may elect to make payment of any Defaulted Interest
      to the persons in whose names the Securities (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 Issuers shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security and the date of the proposed payment, and at the same
      time the Issuers shall deposit with the Trustee an amount of cash 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 cash when
      deposited to be held in trust for the benefit of the persons entitled to
      such Defaulted Interest as provided in this clause (1). 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 Issuers of such Special Record Date and,
      in the name and at the expense of the Issuers, 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 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 mailed
      as aforesaid, such Defaulted Interest shall be paid to the persons in
      whose names the Securities (or their respective predecessor Securities)
      are registered on such Special Record Date and shall no longer be payable
      pursuant to the following clause (2).

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

                                       45
<PAGE>
      exchange, if, after notice given by the Issuers to the Trustee of the
      proposed payment pursuant to this clause, such manner shall be deemed
      practicable by the Trustee in its sole discretion.

            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon 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 2.13.     CUSIP Numbers.

            Neither the Issuers nor the Trustee shall have any responsibility
for any defect in the CUSIP number that appears on any Security, check, advice
of payment or redemption notice, and any such document may contain a statement
to the effect that CUSIP numbers have been assigned by an independent service
for convenience of reference and that neither the Issuers nor the Trustee shall
be liable for any inaccuracy in such numbers.

                                   ARTICLE III
                                   REDEMPTION

            SECTION 3.1.      Rights of Redemption.

            (a) In addition to the provisions of Sections 4.14 and 11.1 hereof,
the Securities are subject to redemption at any time on or after June 15, 2008,
at the option of the Issuers, in whole or in part, subject to the conditions,
and at the Redemption Prices, specified in the form of Security attached hereto
as Exhibit A, together with accrued and unpaid interest, if any, to the
Redemption Date (subject to the rights of holders of record on relevant record
dates to receive interest due on an interest payment date).

            (b) In addition, at any time prior to June 15, 2006, the Issuers, at
their option, may use the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings in a single transaction or a series of
related transactions to redeem up to an aggregate of 35% of the aggregate
principal amount of Securities originally issued under this Indenture at a
redemption price equal to 110.125% of the aggregate principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the redemption date
(subject to the rights of holders of record on relevant record dates to receive
interest due on an interest payment date); provided that at least 65% of the
initial aggregate principal amount of Securities remains outstanding immediately
after the occurrence of such redemption; provided, further, that any such
redemption with respect to a Strategic Equity Offering may not occur in
connection with or after the occurrence of a Change of Control; provided,
further, that any such net proceeds received by Centennial are first contributed
to the Company as a capital contribution prior to such redemption. In order to
effect the foregoing redemption, the Issuers must mail a notice of redemption no
later than 30 days after the closing of the related Public Equity Offering or
Strategic Equity Offering and must consummate such redemption within 60 days of
the closing of the Public Equity Offering or Strategic Equity Offering.

            (c) In addition, the Securities may be redeemed upon a Change of
Control at any time prior to June 15, 2008, at the option of the Issuers, in
whole and not in part, within 60

                                       46
<PAGE>
days of such Change of Control at a redemption price equal to (i) 100% of the
principal amount of the Securities, plus (ii) accrued interest to the redemption
date (subject to the rights of holders of record on relevant record dates to
receive interest due on an interest payment date) plus (iii) the Applicable
Premium, if any. In no event will the redemption price of the Securities be less
than 105.063% (the Redemption Price for the Securities on June 15, 2008) of the
principal amount of the Securities, plus accrued interest to the applicable
Redemption Date.

            SECTION 3.2.      Notices to Trustee.

            If the Issuers elect to redeem Securities pursuant to Paragraph 5 of
the Securities, they shall notify the Trustee in writing of the Redemption Date
and the principal amount of Securities to be redeemed and whether they want the
Trustee to give notice of redemption to the Holders.

            If the Issuers elect to reduce the principal amount of Securities to
be redeemed pursuant to Paragraph 5 of the Securities by crediting against any
such redemption Securities they have not previously delivered to the Trustee for
cancellation, they shall so notify the Trustee of the amount of the reduction
and deliver such Securities with such notice, provided that no Securities issued
on the date of this Indenture received by the Issuers in exchange for Exchange
Securities may be made the basis for such credit.

            The Issuers shall give each notice to the Trustee provided for in
this Section 3.2 at least 45 days before the Redemption Date (unless a shorter
notice shall be satisfactory to the Trustee). Any such notice may be canceled at
any time prior to notice of such redemption being mailed to any Holder and shall
thereby be void and of no effect.

            SECTION 3.3.      Selection of Securities to Be Redeemed.

            If less than all of the Securities are to be redeemed pursuant to
Paragraph 5 thereof, the Trustee shall select the Securities or portions thereof
for redemption in compliance with the requirements of the principal national
securities exchange, if any, on which the Securities are listed, or if the
Securities are not so listed, on a pro rata basis, by lot or by any other manner
as the Trustee shall determine to be fair and appropriate; provided, that any
such redemption pursuant to the provisions relating to a Public Equity Offering
or a Strategic Equity Offering shall be made on a pro rata basis or on as nearly
a pro rata basis as practicable (subject to the procedures of any applicable
Depositary, legal and stock exchange requirements). The Trustee shall make the
selection from the Securities outstanding and not previously called for
redemption and shall promptly notify the Issuers in writing of the Securities
selected for redemption and, in the case of any Security selected for partial
redemption, the principal amount thereof to be redeemed. The Securities may be
redeemed in part pursuant to this Section 3.3 in multiples of $1,000 only. The
Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Securities that have denominations larger
than $1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.

                                       47
<PAGE>
            SECTION 3.4.      Notice of Redemption.

            At least 30 days and not more than 60 days before a Redemption Date,
the Issuers shall mail a notice of redemption by first-class mail, postage
prepaid, to the Trustee and each Holder whose Securities are to be redeemed to
such Holder's last address as then shown upon the books of the Registrar. At the
Issuers' request, the Trustee shall give the notice of redemption in the
Issuers' names and at the Issuers' expense. Each notice for redemption shall
identify the Securities to be redeemed and shall state:

                  (A)   the Redemption Date;

                  (B) the Redemption Price, including the amount of accrued and
            unpaid interest, if any, to be paid upon such redemption;

                  (C)   the name, address and telephone number of the Paying
            Agent;

                  (D) that Securities called for redemption must be surrendered
            to the Paying Agent at the address specified in such notice to
            collect the Redemption Price;

                  (E) that, unless (a) the Issuers default in their obligation
            to deposit cash with the Paying Agent in accordance with Section 3.6
            hereof or (b) such redemption payment is prohibited pursuant to this
            Indenture, interest on Securities (or portion thereof) called for
            redemption ceases to accrue on and after the Redemption Date and the
            only remaining right of the Holders of such Securities is to receive
            payment of the Redemption Price, including any accrued and unpaid
            interest to the Redemption Date, upon surrender to the Paying Agent
            of the Securities called for redemption and to be redeemed;

                  (F) if any Security is being redeemed in part, the portion of
            the principal amount, equal to $1,000 or any integral multiple
            thereof, of such Security to be redeemed and that, after the
            Redemption Date, and upon surrender of such Security, a new Security
            or Securities in aggregate principal amount equal to the unredeemed
            portion thereof will be issued;

                  (G) if less than all the Securities are to be redeemed, the
            identification of the particular Securities (or portion thereof) to
            be redeemed, as well as the aggregate principal amount of such
            Securities to be redeemed and the aggregate principal amount of
            Securities to be outstanding after such partial redemption;

                  (H)   the CUSIP number of the Securities to be redeemed; and

                  (I) that the notice is being sent pursuant to this Section 3.4
            and pursuant to the optional redemption provisions of Paragraph 5 of
            the Securities.

                                       48
<PAGE>
            SECTION 3.5.      Effect of Notice of Redemption.

            Once notice of redemption is mailed in accordance with Section 3.4,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price, including any accrued and unpaid interest and
Additional Interest, if any, to the Redemption Date. Upon surrender to the
Trustee or Paying Agent, such Securities called for redemption shall be paid at
the Redemption Price, including interest and Additional Interest, if any,
accrued and unpaid to the Redemption Date; provided that if the Redemption Date
is after a regular Record Date and on or prior to the Interest Payment Date, the
accrued interest shall be payable to the Holder of the redeemed Securities
registered on the relevant Record Date; and provided, further, that if a
Redemption Date is a Legal Holiday, payment shall be made on the next succeeding
Business Day and no interest shall accrue for the period from such Redemption
Date to such succeeding Business Day.

            SECTION 3.6.      Deposit of Redemption Price.

            By 10:00 a.m. on, or prior to, the Redemption Date, the Issuers
shall deposit with the Paying Agent (other than the Issuers or an Affiliate of
the Issuers) cash sufficient to pay the Redemption Price of, including any
accrued and unpaid interest on, all Securities to be redeemed on such Redemption
Date (other than Securities or portions thereof called for redemption on that
date that have been delivered by the Issuers to the Trustee for cancellation).
The Paying Agent shall promptly return to the Company any cash so deposited
which is not required for that purpose.

            If the Issuers comply with the preceding paragraph and the other
provisions of this Article III and payment of the Securities called for
redemption is not prohibited under this Indenture, interest on the Securities to
be redeemed will cease to accrue on the applicable Redemption Date, whether or
not such Securities are presented for payment. Notwithstanding anything herein
to the contrary, if any Security surrendered for redemption in the manner
provided in the Securities shall not be so paid upon surrender for redemption
because of the failure of the Issuers to comply with the preceding paragraph,
interest shall continue to accrue and be paid from the Redemption Date until
such payment is made on the unpaid principal, and, to the extent lawful, on any
interest not paid on such unpaid principal, in each case at the rate and in the
manner provided in Section 4.1 hereof and the Securities.

            SECTION 3.7.      Securities Redeemed in Part.

            Upon surrender of a Security that is to be redeemed in part, the
Issuers shall execute and the Trustee shall authenticate and deliver to the
Holder, without service charge to the Holder, a new Security or Securities equal
in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE IV
                                    COVENANTS

            SECTION 4.1.      Payment of Securities.

            The Issuers shall pay the principal of, premium, if any, and
interest and Additional Interest, if any, on the Securities on the dates and in
the manner provided in the Securities. An installment of principal of, premium,
if any, or interest and Additional Interest, if any, on the Securities shall be
considered paid by the Issuers on the date it is due if the Trustee or Paying
Agent (other than the Issuers or an Affiliate of the Issuers) holds for the
benefit of the Holders, on or before 10:00 a.m. New York City time on that date,
cash deposited and designated for and sufficient to pay the installment. The
Issuers shall pay interest on overdue principal, premium, if any, and on overdue
installments of interest and Additional Interest, if any, at the rate specified
in the Securities compounded semi-annually, to the extent lawful.

            SECTION 4.2.      Maintenance of Office or Agency.

            The Issuers shall maintain in the Borough of Manhattan, The City of
New York, an office or agency where Securities may be presented or surrendered
for payment, where Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Issuers in respect of the
Securities and this Indenture may be served. The Issuers shall give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Issuers shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the address of the Trustee set forth in Section 12.2. The Issuers
may also from time to time designate one or more other offices or agencies where
the Securities 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 Issuers of their
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such purposes. The Issuers shall 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. The Issuers hereby initially
designate the Corporate Trust Office as such office.

Restricted Subsidiary of the Company from Unrestricted Subsidiaries, or from
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (valued
in each case as provided in the definition of "Investments") since the Existing

the substantially concurrent issuance of new Subordinated Indebtedness of the
Company, provided that any such new Subordinated Indebtedness (1) shall be in a
principal amount that does not exceed the principal amount so refinanced (or, if
such Subordinated Indebtedness provides for an amount less than the principal
amount thereof to be due and payable upon a declaration of acceleration thereof,
then such lesser amount as of the date of determination), plus the lesser of (I)

that in no event shall such amount exceed the aggregate amount of Cash from
Minority Cellular Investment Interests received by the Company net of all taxes
(on a consolidated basis) or capital contributions required to be paid in
respect thereof; and provided further that with respect to any loans, advances,
dividends or distributions after giving effect thereto, the Company would be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Annual Operating Cash Flow Ratio test contained in the second paragraph of
Section 4.11; (x) the declaration and payment of dividends or distributions to

respect of such Capital Stock as a result of a stock split, recapitalization,

other Restricted Payments in an aggregate amount not to exceed $2 million.

            In determining the aggregate amount expended for Restricted Payments
in accordance with clause (d) of the first paragraph of this Section 4.3, 100%
of the amounts expended under clauses (i), (ii) (to the extent the Net Proceeds

aggregate Net Proceeds calculation pursuant to clause (ii) of clause (d) of the
first paragraph of this Section 4.3), (iv), (v), (x), (xi) and (xii) of the
immediately preceding paragraph shall be deducted.

            SECTION 4.4.      Corporate Existence.

            Subject to Article V, each of the Issuers shall do or cause to be

Company's Restricted Subsidiaries in accordance with the respective
organizational documents of each of them and the rights (charter and statutory)
and corporate franchises of the Issuers and each of the Company's Restricted
Subsidiaries; provided, however, that the Issuers shall not be required to
preserve, with respect to itself, any right or franchise, and with respect to
any Restricted Subsidiaries of the Company, any such existence, right or
franchise, if the Company shall determine that the preservation thereof is no
longer desirable in the conduct of the business of such entity.

            SECTION 4.5.      Payment of Taxes and Other Claims.

            Except with respect to items which are not material to the Company
on a Consolidated basis, Centennial and the Company shall, and the Company shall
cause each of its Restricted Subsidiaries to, pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges (including withholding taxes and any
penalties, interest and additions to taxes) levied or imposed upon Centennial,
the Company or any of the Company's Restricted Subsidiaries or any of their
respective properties and assets and (ii) all lawful claims, whether for labor,
materials, supplies, services or anything else, which have become due and
payable and which by law have or may become a Lien upon the property and assets
of Centennial, the Company or any of the Company's Restricted Subsidiaries;
provided, however, that the Issuers shall not be required to

                                       53
<PAGE>
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which disputed amounts adequate
reserves have been established in accordance with GAAP.

            SECTION 4.6.      Maintenance of Properties and Insurance.

            Centennial and the Company shall cause all material properties used
or useful to the conduct of their respective business and the business of each
of the Company's Restricted Subsidiaries to be maintained and kept in reasonably
good condition, repair and working order (reasonable wear and tear excepted) and
shall cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in its reasonable judgment may be
necessary, so that the business carried on in connection therewith may be
properly conducted at all times; provided, however, that nothing in this Section
4.6 shall prevent the Issuers from discontinuing any operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is in the judgment of the Board of Directors of the Company, desirable
in the conduct of the business of such entity.

            Centennial and the Company shall each provide, or cause to be
provided, for themselves and each of the Company's Restricted Subsidiaries,
insurance (including appropriate self-insurance) against loss or damage of the
kinds that, in the reasonable, good faith opinion of the Issuers is adequate and
appropriate for the conduct of the business of Centennial, the Company and such
Restricted Subsidiaries, with (except for self-insurance) reputable insurers or
with the government of the United States of America or an agency or
instrumentality thereof, in such amounts, with such deductibles, and by such
methods, in the reasonable, good faith opinion of the Issuers as are adequate
and appropriate for the conduct of the business of Centennial, the Company and
such Restricted Subsidiaries in a prudent manner for entities similarly situated
in the industry, unless failure to provide such insurance (together with all
other such failures) would not have a material adverse effect on the financial
condition or results of operations of Centennial and its Restricted Subsidiaries
or the Company or such Restricted Subsidiaries, as the case may be.

            SECTION 4.7.      Compliance Certificate; Notice of Default.

            (a) The Issuers shall deliver to the Trustee within 120 days after
the end of its respective fiscal year an Officers' Certificate (one of the
signers being the principal executive officer, principal financial officer or
principal accounting officer) complying with Section 314(a)(4) of the TIA and
stating that a review of its activities and the activities of its Subsidiaries
during the preceding fiscal year, as applicable, has been made under the
supervision of the signing Officers with a view to determining whether the
Issuers have kept, observed, performed and fulfilled their obligations under
this Indenture and further stating, as to each such Officer signing such
certificate, whether or not the signer knows of any failure by the Issuers or
any Subsidiary of the Issuers to comply with any conditions or covenants in this
Indenture and, if such signer does know of such a failure to comply, the
certificate shall describe such failure with particularity. The Officers'
Certificate shall also notify the Trustee should the relevant fiscal year end on
any date other than the current fiscal year end date which currently is May 31.

                                       54
<PAGE>
            (b) The Issuers shall, so long as any of the Securities are
outstanding, deliver to the Trustee, within five Business Days of becoming aware
of any Default, Event of Default or fact which would prohibit the making of any
payment to or by the Trustee in respect of the Securities, an Officers'
Certificate specifying such Default, Event of Default or fact and what action
the Issuers are taking or proposes to take with respect thereto. The Trustee
shall not be deemed to have knowledge of any Default, any Event of Default or
any such fact unless one of its Trust Officers receives notice thereof from the
Issuers or any of the Holders.

            SECTION 4.8.      Provision of Financial Statements.

            Whether or not Centennial is subject to Section 13(a) or 15(d) of
the Exchange Act, so long as any Securities are outstanding, Centennial will, to
the extent permitted under the Exchange Act, file with the Commission the annual
reports, quarterly reports and other documents which Centennial would have been
required to file with the Commission pursuant to Section 13(a) or 15(d) if it
were so subject, such documents to be filed with the Commission on or prior to
the date (the "Required Filing Date") by which Centennial would have been
required so to file such documents if it were so subject. Centennial will also
in any event (x) within 15 days of each Required Filing Date (i) transmit by
mail to all holders, as their names and addresses appear in the security
register, without cost to such holders and (ii) file with the Trustee copies of
the annual reports, quarterly reports and other documents which Centennial would
have been required to file with the Commission pursuant to Section 13(a) or
15(d) of the Exchange Act if Centennial were subject to either of such Sections
and (y) if filing such documents by Centennial with the Commission is not
permitted under the Exchange Act, promptly upon written request and payment of
the reasonable cost of duplication and delivery, supply copies of such documents
to any prospective purchaser of Securities at Centennial's cost. So long as any
of the Securities remain outstanding, Centennial will make available to any
prospective purchaser of Securities or beneficial owner of Securities in
connection with any sale thereof the information required by Rule 144A(d)(4)
under the Securities Act, until such time as the Issuers have either exchanged
the Securities for securities identical in all material respects which have been
registered under the Securities Act or until such time as the holders thereof
have disposed of such Securities pursuant to an effective registration statement
under the Securities Act.

            SECTION 4.9. Limitation on Priority Indebtedness and Pari Passu
Indebtedness.

            The Company will not and will not permit any of its Restricted
Subsidiaries to Incur any Priority Indebtedness or Pari Passu Indebtedness if
the Company's Priority and Pari Passu Debt to Cash Flow Ratio, after giving
effect to the incurrence of such Indebtedness and the application of the
proceeds therefrom, would have been 4.75 to 1.0 or higher. The foregoing
limitation shall not apply to (a) any Indebtedness otherwise permitted to be
incurred pursuant to clauses (i), (ii), (iii), (iv), (v), (vi) (but only to the
extent the guarantee permitted by such clause (vi) relates to any Indebtedness
permitted to be incurred by this sentence), (viii), (ix), (x), (xi), and (xii)
of the third paragraph of Section 4.11, or (b) Pari Passu Indebtedness permitted
to be incurred pursuant to clauses (vii) and (xiii) of the third paragraph of
Section 4.11 ((a) and (b) together, "Other Permitted Indebtedness"). For
purposes of determining compliance with this Section 4.9, in the event an item
of Indebtedness meets the criteria of more than one category of exceptions
contained in the previous sentence or meets the criteria of the first sentence
of this

                                       55
<PAGE>
Section 4.9, the Company may, in its sole discretion classify such item of
Indebtedness on the date of incurrence in any manner that complies with this
Section 4.9 and such item of Indebtedness will be treated as having been
incurred pursuant to only one of such exceptions or pursuant to the first
sentence of this Section 4.9.

            SECTION 4.10.     Limitation on Transactions With Related Persons.

            The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction") involving
in one or a series of related transactions an aggregate consideration in excess
of $5.0 million, unless (a) such Affiliate Transaction is on terms that are not
materially less favorable to the Company or the relevant Restricted Subsidiary
than those that would have been obtained in a comparable transaction by the
Company or such Restricted Subsidiary with an unrelated Person and the Company
delivers an Officer's Certificate to the Trustee certifying that such Affiliate
Transaction complies with this clause (a) and (b) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $10.0 million, the Company delivers to the Trustee a
resolution adopted by the majority of the Disinterested Directors approving such
Affiliate Transaction and set forth in an Officer's Certificate certifying that
such Affiliate Transaction complies with clause (a) above.

            The foregoing provisions will not apply to the following: (i)
transactions between or among the Company and/or any of its Restricted
Subsidiaries; (ii) Restricted Payments permitted by the provisions of this
Indenture described above under Section 4.3; (iii) the payment of annual
management, consulting, monitoring and advisory fees and related expenses to
Welsh Carson, Blackstone and their respective Affiliates in an amount in any
calendar year not to exceed the greater of (a) $1 million or (b) 1% of Annual
Operating Cash Flow; (iv) the payment of reasonable and customary fees paid to,
and indemnity provided on behalf of, officers, directors, employees or
consultants of the Company or any Restricted Subsidiary; (v) payments by the
Company or any of its Restricted Subsidiaries to Welsh Carson, Blackstone and
their respective Affiliates made for any financial advisory, financing,
underwriting or placement services or in respect of other investment banking
activities, including, without limitation, in connection with acquisitions or
divestitures which payments are approved by a majority of the Board of Directors
of the Company in good faith; (vi) transactions with respect to which the
Company or any of its Restricted Subsidiaries, as the case may be, delivers to
the Trustee a letter from an investment banking, appraisal or accounting firm of
national standing stating that such transaction is fair to the Company or such
Restricted Subsidiary from a financial point of view; (vii) payments or loans to
employees or consultants which are approved by a majority of the Board of
Directors of the Company in good faith; (viii) any agreement as in effect on the
Issue Date or any amendment thereto (so long as any such amendment is not
disadvantageous to the Holders of the Securities in any material respect) or any
transaction contemplated thereby; (ix) the existence of, or the performance by
the Company or any of its Restricted Subsidiaries of its obligations under the
terms of, the Recapitalization Documents and any stockholders agreement
(including any registration rights agreement or purchase agreement related
thereto) to which it is a party on the Issue Date and any similar agreements
which it may enter into thereafter;

                                       56
<PAGE>
provided, however, that the existence of, or the performance by the Company or
any of its Restricted Subsidiaries of obligations under any future amendment to
any such existing agreement or under any similar agreement entered into after
the Issue Date shall only be permitted by this clause; and (x) any payment
pursuant to a tax sharing agreement between the Company and any other Person
with which the Company is required or permitted to file a consolidated tax
return or with which the Company is or could be part of a consolidated, combined
or unitary group for tax purposes, which payments are not in excess of the tax
liabilities attributable solely to the Company and its Restricted Subsidiaries
(as a consolidated, combined or unitary group).

            SECTION 4.11. Limitation on Incurrence of Additional Indebtedness.

            The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, issue, create, incur, assume, guarantee
or otherwise directly or indirectly become liable for, or otherwise become
responsible for, contingently or otherwise (individually or collectively, to
"Incur" or, as appropriate, an "Incurrence"), any Indebtedness (including any
Acquired Indebtedness). Neither the accrual of interest (including the issuance
of "pay in kind" securities or similar instruments in respect of such accrued
interest) pursuant to the terms of Indebtedness Incurred in compliance with this
Section 4.11, nor the accretion of original issue discount, nor the mere
extension of the maturity of any Indebtedness shall be deemed to be an
Incurrence of Indebtedness.

            Notwithstanding the foregoing, the Company and any Guarantor may
Incur Indebtedness (including Acquired Indebtedness) and any Restricted
Subsidiary may Incur Acquired Indebtedness if the Company's Annual Operating
Cash Flow Ratio, after giving effect to the Incurrence of such Indebtedness and
the application of the proceeds therefrom, would have been less than 7.5 to 1.0
thereafter.

            In addition, the foregoing limitations will not apply to the
Incurrence of the following (together, "Permitted Indebtedness"):

            (i) Indebtedness of the Company or any Restricted Subsidiary under
      the Credit Facility in an aggregate principal amount at any one time
      outstanding not to exceed $915,240,000, reduced by permanent reductions in
      commitments in satisfaction of the Net Cash Proceeds application
      requirement set forth in Section 4.14; provided, that any Indebtedness
      under the Credit Facility outstanding on the Issue Date will be deemed to
      have been incurred under this clause (i);
            (ii) Indebtedness pursuant to the Securities or existing on the
      Issue Date (other than under the Credit Facility) and Refinancing
      Indebtedness Incurred to refinance Indebtedness incurred pursuant to this
      clause (ii);

            (iii) Indebtedness between the Company and any Restricted Subsidiary
      of the Company or between Restricted Subsidiaries of the Company, provided
      that, in the case of Indebtedness of the Company, such obligations shall
      be unsecured and subordinated in all respects to the Holders' rights
      pursuant to the Securities; provided, further, that (a) any disposition or
      transfer of any such Indebtedness to a Person (other than a disposition or

                                       57
<PAGE>
      transfer to the Company or a Restricted Subsidiary) shall be deemed to be
      an Incurrence of such Indebtedness by the obligor not permitted by this
      clause (iii), and (b) any transaction pursuant to which any Restricted
      Subsidiary, which has Indebtedness owing to the Company or any other
      Restricted Subsidiary, ceases to be a Restricted Subsidiary shall be
      deemed to be the Incurrence of Indebtedness by such Restricted Subsidiary
      that is not permitted by this clause (iii);

            (iv) Capitalized Lease Obligations, Purchase Money Indebtedness of
      the Company and any Restricted Subsidiary and any Refinancing Indebtedness
      incurred to refinance Indebtedness in respect thereof in an aggregate
      amount or aggregate principal amount, as the case may be, outstanding at
      any time not to exceed in the aggregate the greater of (x) $75 million and
      (y) 5% of the Company's Total Assets; provided that in the case of
      Purchase Money Indebtedness, such Indebtedness shall not constitute more
      than 100% of the cost (determined in accordance with GAAP) to the Company
      or such Restricted Subsidiary of the property purchased or leased with the
      proceeds thereof;

            (v) Indebtedness of the Company or any Restricted Subsidiary arising
      from agreements providing for indemnification, adjustment of purchase
      price or similar obligations, or from guarantees or letters of credit,
      surety bonds or performance bonds securing any obligations of the Company
      or its Restricted Subsidiaries pursuant to such agreements, in any case
      Incurred in connection with the disposition of any business, assets or
      Restricted Subsidiary of the Company to the extent none of the foregoing
      results in the obligation to repay an obligation for money borrowed by any
      Person;

            (vi) any guarantee by any Restricted Subsidiary of the Credit
      Facility or any other Indebtedness made in accordance with the provisions
      of Section 4.19;

            (vii) Indebtedness Incurred by the Company or any of its Restricted
      Subsidiaries in connection with the acquisition of a new Restricted

      months for which audited or unaudited financial statements are available
      are from a Related Business, or of property, businesses or assets which,
      or Capital Stock of a Person all or substantially all of whose assets, are
      of a type generally used in a Related Business and any Refinancing
      Indebtedness in respect thereof; provided that the principal amount (or
      accreted value, as applicable) of such Indebtedness and any Refinancing
      Indebtedness in respect thereof, together with any other outstanding
      Indebtedness Incurred pursuant to this clause (vii), does not exceed $40
      million in the aggregate at any one time outstanding; and provided,
      further, that the principal amount of Indebtedness that may be incurred
      pursuant to this clause (vii) and clause (xi) by any individual Restricted
      Subsidiary that is not a Guarantor shall not exceed $25 million in the
      aggregate at any one time outstanding;

            (viii) Indebtedness of the Company or any Restricted Subsidiary

      credit or the Incurrence of such Indebtedness, such obligations are
      reimbursed within 30 days following such drawing or Incurrence;

            (ix) Interest Rate Protection Obligations relating to (A)
      Indebtedness of the Company or any Restricted Subsidiary (which
      Indebtedness is otherwise permitted to be Incurred under this Section
      4.11) or (B) Indebtedness for which a lender has provided a commitment in
      an amount reasonably anticipated to be Incurred by the Company or any
      Restricted Subsidiary in the 12 months after such Interest Rate Protection
      Obligations has been Incurred; provided, however, that the notional
      principal amount of such Interest Rate Protection Obligations does not
      exceed the principal amount of the Indebtedness (including Indebtedness
      subject to commitments) to which such Interest Rate Protection Obligations
      relate;

            (x) Currency Hedging Agreements relating to (A) Indebtedness of the
      Company or any Restricted Subsidiary and/or (B) obligations to purchase or
      sell assets or properties, in each case, incurred in the ordinary course
      of business of the Company or any Restricted Subsidiary; provided,
      however, that such Currency Hedging Agreements do not increase the
      Indebtedness or other obligations of the Company or any Restricted
      Subsidiary outstanding other than as a result of the fluctuations in
      foreign currency exchange rates or by reason of fees, indemnities and
      compensation payable thereunder;

            (xi) Indebtedness of the Company or any Guarantor (other than as
      otherwise permitted pursuant to this Section 4.11) not to exceed $125
      million in the aggregate at any one time outstanding; provided, that the
      Company's Restricted Subsidiaries other than any Guarantor may Incur up to
      $75 million in the aggregate at any one time outstanding of the $125
      million of Indebtedness which may be Incurred pursuant to this clause
      (xi);

            (xii) Refinancing Indebtedness Incurred to extend, renew, replace or
      refund Indebtedness permitted under the second paragraph of this covenant
      or clause (ii) of this paragraph (plus the lesser of (a) the stated amount
      of any premium or other payment required to be paid in connection with
      such a refinancing pursuant to the terms of the Indebtedness being
      refinanced or (b) the amount of premium or other payment actually paid at
      such time to refinance the Indebtedness, plus, in either case, the amount
      of expenses of the Company reasonably incurred in connection with such
      refinancing); and

            (xiii) other Indebtedness of the Company or any Restricted
      Subsidiary in an amount not greater than the aggregate amount of Net Cash
      Proceeds from the sale of Capital Stock of the Company or cash
      contributions made to the capital of the Company (other than in exchange
      for Disqualified Capital Stock); provided that the amount of such cash
      contributions ("Excluded Cash Contributions") are designated in an
      Officer's Certificate as Excluded Cash Contributions and shall not be
      included in the computation of the amount of Restricted Payments which the
      Company can make pursuant to Section 4.3.

            For purposes of determining compliance with this Section 4.11, in
      the event that an item of Indebtedness meets the criteria of more than one
      of the categories of permitted Indebtedness described in clauses (ii)
      through (xiii) above or is entitled to be Incurred pursuant to the second
      paragraph of this covenant, the Company may, in its sole discretion,
      classify such item of Indebtedness on the date of Incurrence in any manner

                                       59
<PAGE>
      that complies with this covenant and such item of Indebtedness will be
      treated as having been Incurred pursuant to only one of such clauses or
      pursuant to the second paragraph hereof.

            SECTION 4.12. Limitation on Restricting Subsidiary Dividends.

            The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, assume or suffer to exist any
consensual encumbrance or restriction on the ability of any Restricted
Subsidiary of the Company to pay dividends or make other distributions on the
Capital Stock of any Restricted Subsidiary of the Company or pay or satisfy any
obligation to the Company or any of its Restricted Subsidiaries or otherwise

any applicable law or any governmental or administrative regulation or order;
(ii) Refinancing Indebtedness permitted under this Indenture, provided that the

the instruments governing the Indebtedness being refinanced immediately prior to
such refinancing; (iii) restrictions with respect solely to a Restricted
Subsidiary of the Company imposed pursuant to a binding agreement which has been
entered into for the sale or disposition of all or substantially all of the
Capital Stock or assets of such Restricted Subsidiary, provided that such
restrictions apply solely to the Capital Stock or assets being sold of such
Restricted Subsidiary; (iv) restrictions contained in any agreement relating to
a Person or real or tangible personal property acquired after the Issue Date
which are not applicable to any Person or property, other than the Person or
property so acquired and which were not put in place in connection with, or in
contemplation of, such acquisition; (v) any agreement (other than those referred
to in clause (iv)) of a Person acquired by the Company or a Restricted
Subsidiary of the Company, which restrictions existed at the time of
acquisition; (vi) contractual encumbrances or restrictions in effect on the
Issue Date (including encumbrances and restrictions relating to the Credit
Facility or the Existing Notes or any other Indebtedness outstanding on the
Issue Date) and customary encumbrances and restrictions contained in the
security agreements related to the Credit Facility each case as such
encumbrances or restrictions may be amended, provided that such encumbrances or
restrictions as amended are no more restrictive in the aggregate than those
contained in contractual encumbrances or restrictions in effect on the Issue
Date; (vii) this Indenture and the Securities; (viii) Purchase Money
Indebtedness and Capitalized Leases, each for property acquired in the ordinary
course of business to the extent such encumbrance or restriction relates to the
property underlying the Purchase Money Indebtedness; (ix) Indebtedness of
Restricted Subsidiaries otherwise permitted to be Incurred pursuant to Section
4.11 and Section 4.13, provided such encumbrances or restrictions in the
aggregate with all other previous encumbrances or restrictions permitted by this
clause (ix), permit payment of cash to the Company in an amount at least equal
to 90% of the Annual Operating Cash Flow for all periods following the
Incurrence of such Indebtedness; (x) restrictions on cash or other deposits or
net worth imposed by customers under contracts entered into in the ordinary
course of business; (xi) customary provisions in joint venture agreements and
other similar agreements entered into in the ordinary course of business to the
extent such encumbrance and restriction relates to the activities and assets of
such joint venture or similar entity and provided that the Annual Operating Cash
Flow determined as of the date of execution of any such joint venture or similar
agreement in all such joint ventures or similar entities which are subject to
such encumbrances or

                                       60
<PAGE>
restrictions do not exceed 10% of the Company's Annual Operating Cash Flow on

            SECTION 4.13. Limitation on Liens.

            The Company will not, and will not cause or permit any Restricted
Subsidiary to, directly or indirectly, create, Incur or affirm any Lien of any
kind (other than a Permitted Lien) securing any Indebtedness (including any
assumption, guarantee or other liability with respect thereto by any Restricted
Subsidiary) upon any property or assets (including any intercompany notes) of
the Company or any Restricted Subsidiary owned on the date of this Indenture or
acquired after the date of this Indenture, or any income or profits therefrom,
unless the Securities are directly secured equally and ratably with the
Indebtedness secured by such Lien. Notwithstanding the foregoing, any Lien
securing the Securities granted pursuant to this Section 4.13 shall be
automatically and unconditionally released and discharged upon the release by
the holders of the Indebtedness described above of their Lien on the property or
assets of the Company or any Restricted Subsidiary (including any deemed release
upon payment in full of all obligations under such Indebtedness), at such time
as the holders of all such Indebtedness also release their Lien on the property
or assets of the Company or such Restricted Subsidiary, or upon any sale,
exchange or transfer to any Person not an Affiliate of the Company of the
property or assets secured by such Lien, or of all of the Capital Stock held by
the Company or any Restricted Subsidiary in, or all or substantially all the
assets of, any Restricted Subsidiary creating such Lien.

            SECTION 4.14. Limitation on Asset Sales and Sales of Subsidiary
Stock.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, in one or a series of related transactions, convey,
sell, transfer, assign or otherwise dispose of, directly or indirectly, any of
its property, businesses or assets, including by merger or consolidation or sale
and leaseback transaction, and including any sale or other transfer or issuance
of any Capital Stock of any Restricted Subsidiary of the Company, whether by the
Company or a Restricted Subsidiary (an "Asset Sale"), unless (1) either (a)
within one year after the date of such Asset Sale, an amount equal to the Net
Cash Proceeds therefrom (the "Asset Sale Offer Amount") are applied to the
optional redemption of the Securities in accordance with the terms of this
Indenture and other Indebtedness of the Company ranking on a parity with the
Securities from time to time outstanding with similar provisions requiring the
Company to make an offer to purchase or to redeem such Indebtedness with the
proceeds from asset sales, pro rata in proportion to the respective principal
amounts (or accreted values in the case of Indebtedness issued with an original
issue discount) of the Securities and such other Indebtedness then outstanding
or to the repurchase of the Securities and such other Indebtedness pursuant to
an irrevocable, unconditional offer (the "Asset Sale Offer") to repurchase such
Indebtedness at a purchase price (the "Asset Sale Offer Price") of 100% of the
principal amount thereof in the case of the Securities or 100% of the principal
amount (or accreted value in the case of Indebtedness issued with an original
issue discount) of such Indebtedness, plus, in each case, accrued interest to
the date of payment, made within one year of such Asset Sale, or (b) within one
year of such Asset Sale, the Asset Sale Offer Amount is (i) invested (or
committed, pursuant to a binding commitment subject only to reasonable,
customary closing conditions, to be invested, and in fact

                                       61
<PAGE>
is so invested, within an additional 90 days) in tangible assets and property
(other than notes, obligations or securities), which in the good faith
reasonable judgment of the Company are of a type used in a Related Business, or
Capital Stock of a Person (which, if such Person becomes a Subsidiary of the
Company by virtue of such Asset Sale, shall initially be designated a Restricted
Subsidiary) all or substantially all of whose assets and property (in the good
faith reasonable judgment of the Company) are of a type used in a Related
Business (provided that, with respect to such Capital Stock, all of the
requirements of the last proviso of clause (v) of the following paragraph shall
have been satisfied) or (ii) used to permanently retire Indebtedness of the
Company or any Guarantor that is Pari Passu Indebtedness or Priority
Indebtedness, (2) with respect to any transaction or related series of
transactions of securities, property or assets with an aggregate Fair Market
Value in excess of $2,500,000, at least 75% of the value of consideration for
the assets disposed of in such Asset Sale (excluding (a) Indebtedness of the
Company or any Guarantor that is Pari Passu Indebtedness under a bank credit
facility (and any Refinancing Indebtedness issued to refinance any such
Indebtedness) or any Priority Indebtedness in each case that is assumed by a
transferee which assumption permanently reduces the amount of Indebtedness
outstanding on the Issue Date and permitted to have been Incurred pursuant to
Section 4.11 (including that in the case of a revolver or similar arrangement
that makes credit available, such commitment is permanently reduced by such
amount), (b) Purchase Money Indebtedness secured exclusively by the assets
subject to such Asset Sale which is assumed by a transferee and (c) marketable
securities that are promptly converted into cash or Cash Equivalents) consists
of cash or Cash Equivalents, provided that any cash or Cash Equivalents received
within 12 months following any such Asset Sale upon conversion of any property
or assets (other than in the form of cash or Cash Equivalents) received in
consideration of such Asset Sale shall be applied promptly in the manner
required of Net Cash Proceeds of any such Asset Sale as set forth above
(provided further that the Company and its Restricted Subsidiaries shall not be
required to receive any cash in connection with the transfer or contribution of
assets to a joint venture), and (3) the Board of Directors of the Company
determines in good faith that the Company or such Restricted Subsidiary, as
applicable, would receive Fair Market Value in consideration of such Asset Sale.
An Asset Sale Offer may be deferred until the accumulated Net Cash Proceeds from
Asset Sales not applied to the uses set forth in (1)(b) above exceeds
$15,000,000 and that each Asset Sale Offer shall remain open for 20 Business
Days following its commencement and no longer, except as otherwise required by
applicable law (the "Asset Sale Offer Period"). Upon expiration of the Asset
Sale Offer Period, the Company shall apply the Asset Sale Offer Amount, plus an
amount equal to accrued interest to the purchase of all Indebtedness properly
tendered (on a pro rata basis as described above if the Asset Sale Offer Amount
is insufficient to purchase all Indebtedness so tendered) at the Asset Sale
Offer Price (together with accrued interest).

            Notwithstanding the foregoing provisions of the prior paragraphs
(1), (2) and (3):

            (i) the Company and its Restricted Subsidiaries may, in the ordinary
      course of business, convey, sell, lease, transfer, assign or otherwise
      dispose of assets acquired and held for resale in the ordinary course of
      business;

            (ii) the Company and its Restricted Subsidiaries may convey, sell,
      lease, transfer, assign or otherwise dispose of assets pursuant to and in
      accordance with Section 5.1;

                                       62
<PAGE>
            (iii) the Company and its Restricted Subsidiaries may sell or
      dispose of damaged, worn out or other obsolete property in the ordinary
      course of business so long as such property is no longer necessary for the
      proper conduct of the business of the Company or such Restricted
      Subsidiary, as applicable;

            (iv) the Company and its Restricted Subsidiaries may convey, sell,
      lease, transfer, assign or otherwise dispose of assets to the Company or
      any of its Restricted Subsidiaries in accordance with the terms of this
      Indenture; and

            (v) the Company and its Restricted Subsidiaries may exchange, in the
      ordinary course of business (or, if otherwise than in the ordinary course
      of business, in the case of exchanges in excess of $15,000,000 upon
      receipt of a favorable written opinion by an independent financial advisor
      of national reputation as to the fairness from a financial point of view
      to the Company or such Restricted Subsidiary of the proposed transaction),
      all or a portion of its property, businesses or assets for property,
      businesses or assets which, or Capital Stock of a Person all or
      substantially all of whose assets, are of a type used in the business of
      the Company on the date of this Indenture or a Related Business (provided
      that such Person shall initially be designated a Restricted Subsidiary if
      such Person becomes a Subsidiary of the Company by virtue of such
      exchange), or a combination of any such property, businesses or assets, or
      Capital Stock of such a Person and cash or Cash Equivalents; provided that
      (i) a majority of the Disinterested Directors of the Board of Directors of
      the Company shall have approved a resolution of the Board of Directors
      that such exchange is fair to the Company or such Restricted Subsidiary,
      as the case may be, and (ii) any cash or Cash Equivalents received
      pursuant to any such exchange shall be applied in the manner applicable to
      Net Cash Proceeds from an Asset Sale as set forth pursuant to the
      provisions of paragraphs (1), (2) and (4) of this Section 4.14; and
      provided, further, that any Capital Stock of a Person received in an Asset
      Sale pursuant to this clause (v) shall be owned directly by the Company or
      a Restricted Subsidiary and, when combined with the Capital Stock of such
      Person already owned by the Company and its Restricted Subsidiaries, shall
      constitute a majority of the voting power and Capital Stock of such
      Person.

            Restricted Payments and Permitted Investments that are made in
compliance with Section 4.3 shall not be deemed to be Asset Sales.

            Any Asset Sale Offer shall be made in compliance with all applicable
laws, rules, and regulations, including, if applicable, Regulation 14E of the
Exchange Act and the rules and regulations thereunder and all other applicable
federal and state securities laws, and any provisions of this Indenture that
conflict with such laws shall be deemed to be superseded by the provisions of
such laws.

            The Company shall accumulate all Net Cash Proceeds and the aggregate
amount of such accumulated Net Cash Proceeds not used for the purposes permitted
and within the time provided by this Section 4.14 is referred to as the
"Accumulated Amount."

            For purposes of this Section 4.14, "Minimum Accumulation Date" means
each date on which the Accumulated Amount exceeds $5,000,000. Not later than 10
Business Days

                                       63
<PAGE>
after each Minimum Accumulation Date, the Company will commence an Asset Sale
Offer to the Holders and holders of other Indebtedness of the Company ranking
pari passu in right of payment with the Securities from time to time outstanding
with similar provisions requiring the Company to make an offer to purchase or to
redeem such Indebtedness with the proceeds from asset sales to purchase, on a
pro rata basis in proportion to the respective principal amounts (or accreted
values in the case of Indebtedness issued with an original issue discount) of
the Securities and such other Indebtedness then outstanding, for cash,
Securities and such other Indebtedness that will have an aggregate principal
amount (and accreted value, as applicable) on the purchase date equal to the
Accumulated Amount, at a purchase price equal to the Asset Sale Offer Price,
plus accrued but unpaid interest, if any, to, and including, the date of
purchase (the "Asset Sale Purchase Date"), which date shall be no later than 30
Business Days after the first date on which the Asset Sale Offer is required to
be made. Notice of an Asset Sale Offer will be sent 20 Business Days prior to
the close of business on the earlier of (a) the third Business Day prior to the
Asset Sale Purchase Date and (b) the third Business Day following the expiration
of the Asset Sale Offer (such earlier date being the "Final Put Date"), by
first-class mail, by the Company to each Holder at its registered address, with
a copy to the Trustee. The notice to the Holders will contain all information,
instructions and materials required by applicable law or otherwise material to
such Holders' decision to tender Securities pursuant to the Asset Sale Offer.
The notice to Holders, which (to the extent consistent with this Indenture)
shall govern the terms of the Asset Sale Offer, shall state:

                  (A) that the Asset Sale Offer is being made pursuant to such
            notice and this Section 4.14;

                  (B) the Asset Sale Offer Amount, the Asset Sale Offer Price
            (including the amount of accrued and unpaid interest), the Final Put
            Date, and the Asset Sale Purchase Date, which Asset Sale Purchase
            Date shall be on or prior to 40 Business Days following the Minimum
            Accumulation Date;

                  (C) that any Security or portion thereof not tendered or
            accepted for payment will continue to accrue interest;

                  (D) that, unless the Issuers default in depositing cash with
            the Paying Agent in accordance with the penultimate paragraph of
            this Section 4.14 or such payment is otherwise prevented, any
            Security, or portion thereof, accepted for payment pursuant to the
            Asset Sale Offer shall cease to accrue interest after the Asset Sale
            Purchase Date;

                  (E) that Holders electing to have a Security, or portion
            thereof, purchased pursuant to an Asset Sale Offer will be required
            to surrender the Security, with the form entitled "Option of Holder
            to Elect Purchase" on the reverse of the Security completed, to the
            Paying Agent (which may not for purposes of this Section 4.14,
            notwithstanding anything this Indenture to the contrary, be the
            Company or any Affiliate of the Company) at the address specified in
            the notice prior to the close of business on the Final Put Date;

                                       64
<PAGE>
                  (F) that Holders will be entitled to withdraw their elections,
            in whole or in part, if the Paying Agent (which may not for purposes
            of this Section 4.14, notwithstanding any other provision of this
            Indenture, be the Company or any Affiliate of the Company) receives,
            up to the close of business on the Final Put Date, a telegram,
            telex, facsimile transmission or letter setting forth the name of
            the Holder, the principal amount of the Securities the Holder is
            withdrawing and a statement that such Holder is withdrawing his
            election to have such principal amount of Securities purchased;

                  (G) that if Indebtedness in a principal amount in excess of
            the principal amount of Securities to be acquired pursuant to the
            Asset Sale Offer is tendered and not withdrawn, the Issuers shall
            purchase Indebtedness on a pro rata basis in proportion to the
            respective principal amounts (or accreted values in the case of
            Indebtedness issued with an original issue discount) thereof (with
            such adjustments as may be deemed appropriate by the Issuers so that
            only Securities in denominations of $1,000 or integral multiples of
            $1,000 shall be acquired);

                  (H) that Holders whose Securities were purchased only in part
            will be issued new Securities equal in principal amount to the
            unpurchased portion of the Securities surrendered; and

                  (I) a brief description of the circumstances and relevant
            facts regarding such Asset Sales.

            On or before an Asset Sale Purchase Date, the Issuers shall (i)
accept for payment Securities or portions thereof properly tendered and not
properly withdrawn pursuant to the Asset Sale Offer on or before the Final Put
Date (on a pro rata basis if required pursuant to paragraph (7) hereof), (ii)
deposit with the Paying Agent cash sufficient to pay the Asset Sale Offer Price
for all Securities or portions thereof so tendered and accepted and (iii)
deliver to the Trustee Securities so accepted together with an Officers'
Certificate stating the Securities or portions thereof being purchased by the
Issuers. The Paying Agent shall on each Asset Sale Purchase Date mail or deliver
to Holders of Securities so accepted payment in an amount equal to the Asset
Sale Offer Price for such Securities, and the Trustee shall promptly
authenticate and mail or deliver to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered. Any
Security not so accepted shall be promptly mailed or delivered by the Issuers to
the Holder thereof. The Trustee shall not be deemed to have notice of any Asset
Sale Purchase Date unless a Trust Officer receives notice thereof from the
Issuers or any Holder.

            If the amount required to acquire all Indebtedness properly tendered
by Holders pursuant to the Asset Sale Offer (the "Acceptance Amount") made
pursuant to this Section 4.14 is less than the Asset Sale Offer Amount, the
excess of the Asset Sale Offer Amount over the Acceptance Amount may be used by
the Company for general corporate purposes without restriction, unless otherwise
restricted by the other provisions of this Indenture. Upon consummation of any
Asset Sale Offer made in accordance with the terms of this Indenture, the
Accumulated Amount will be reduced to zero irrespective of the amount of
Indebtedness tendered pursuant to the Asset Sale Offer.

            SECTION 4.15. Waiver of Stay, Extension or Usury Laws.

            The Issuers covenant (to the extent that they may lawfully do so)
that they will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law which would prohibit or forgive the Issuers from paying
all or any portion of the principal of, premium of, or interest on the
Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this
Indenture; and (to the extent that it may lawfully do so) the Issuers hereby
expressly waive all benefit or advantage of any such law, and covenant that they
will not hinder, delay or impede the execution of any power herein granted to

though no such law had been enacted.

            SECTION 4.16. [INTENTIONALLY OMITTED].

            SECTION 4.17. Limitation on Unrestricted Subsidiaries.

            The Company may designate any Subsidiary (other than Centennial or a
Guarantor) as an "Unrestricted Subsidiary" under this Indenture (a
"Designation") only if:

                  (a) no Default shall have occurred and be continuing at the
            time of or after giving effect to such Designation;

                  (b) the Company would be permitted to make an Investment at
            the time of Designation (assuming the effectiveness of such
            Designation) pursuant to Section 4.3 above in an amount (the
            "Designation Amount") equal to the greater of (1) the net book value
            of the Company's interest in such Subsidiary calculated in
            accordance with GAAP or (2) the Fair Market Value of the Company's
            interest in such Subsidiary as determined in good faith by the
            Company's Board of Directors;

                  (c) such Unrestricted Subsidiary does not own any Capital
            Stock in any Restricted Subsidiary of the Company which is not
            simultaneously being designated an Unrestricted Subsidiary;

                  (d) such Unrestricted Subsidiary is not liable, directly or
            indirectly, with respect to any Indebtedness other than Indebtedness
            of an Unrestricted Subsidiary, provided that an Unrestricted
            Subsidiary may provide a Guarantee for the Securities; and

                  (e) such Unrestricted Subsidiary is not a party to any
            agreement, contract, arrangement or understanding at such time with
            the Company or any Restricted Subsidiary unless the terms of any
            such agreement, contract, arrangement or understanding are no less
            favorable to the Company or such Restricted Subsidiary than those
            that might be obtained at the time from Persons who are not
            Affiliates of the Company or, in the event such condition is not
            satisfied, the value of such agreement, contract, arrangement or
            understanding to such Unrestricted Subsidiary shall be deemed a
            Restricted Payment.

                                       66
<PAGE>
            In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
4.3 for all purposes of this Indenture in the Designation Amount.

            The Company shall not and shall not cause or permit any Restricted
Subsidiary to at any time (x) provide credit support for (provided that
operational contracts in the ordinary course of business shall not be deemed
credit support), or subject any of its property or assets (other than the
Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any
Indebtedness of any Unrestricted Subsidiary (including any undertaking,
agreement or instrument constituting such Indebtedness) (other than Permitted
Investments in Unrestricted Subsidiaries) or (y) be directly or indirectly
liable for any Indebtedness of any Unrestricted Subsidiary. For purposes of the
foregoing, the Designation of a Subsidiary of the Company as an Unrestricted
Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of
such Subsidiary as Unrestricted Subsidiaries.

            The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

                  (a) no Default shall have occurred and be continuing at the
            time of and after giving effect to such Revocation;

                  (b) all Liens and Indebtedness of such Unrestricted Subsidiary
            outstanding immediately following such Revocation would, if Incurred
            at such time, have been permitted to be Incurred for all purposes of
            this Indenture; and

                  (c) unless such redesignated Subsidiary shall not have any
            Indebtedness outstanding (other than Indebtedness that is Permitted
            Indebtedness and Other Permitted Indebtedness), immediately after
            giving effect to such proposed Revocation, and after giving pro
            forma effect to the Incurrence of any such Indebtedness of such
            redesignated Subsidiary as if such Indebtedness was Incurred on the
            date of the Revocation, the Company could Incur $1.00 of additional
            Indebtedness (other than Indebtedness that is Permitted Indebtedness
            and Other Permitted Indebtedness) pursuant to Section 4.11.

            All Designations and Revocations must be evidenced by a resolution
of the Board of Directors of the Company delivered to the Trustee certifying
compliance with the foregoing provisions.

            SECTION 4.18. Limitation on Lines of Business.

            Neither the Company nor any of its Restricted Subsidiaries shall
directly or indirectly engage in any line or lines of business activity other
than that which, in the reasonable, good faith judgment of the Board of
Directors of the Company, is a Related Business.

            SECTION 4.19. Limitation on Issuances of Guarantees.

(a) The Company will not cause or permit any Restricted Subsidiary (other than a
Guarantor), directly or indirectly, to guarantee, assume or in any other manner
become liable with respect to any Indebtedness (other than a guarantee) of the
Company or any

                                       67
<PAGE>
Restricted Subsidiary (other than under the Credit Facility) unless such
Restricted Subsidiary simultaneously executes and delivers a supplemental
indenture to this Indenture providing for a Guarantee of the Securities on the
same terms as the guarantee of such Indebtedness except that such guarantee need
not be secured unless required pursuant to Section 4.13 if such Indebtedness is
by its terms expressly subordinated to the Securities, any such assumption,
guarantee or other liability of such Restricted Subsidiary with respect to such
Indebtedness shall be subordinated to such Restricted Subsidiary's Guarantee of
the Securities at least to the same extent as such Indebtedness is subordinated
to the Securities; provided that, unless the Existing Notes are guaranteed by a
particular Restricted Subsidiary (other than a Guarantor), the foregoing shall
not be applicable to any guarantee of (A) Indebtedness of a Foreign Restricted
Subsidiary by a Foreign Restricted Subsidiary and (B) Indebtedness of such
Restricted Subsidiary that existed at the time it became a Restricted Subsidiary
and was not Incurred in connection with, or in contemplation of, such Person
becoming a Restricted Subsidiary and any guarantees of Indebtedness that could
have been incurred by such Restricted Subsidiary directly pursuant to Section
4.11.

            (b) Notwithstanding the foregoing, any Guarantee by a Restricted
Subsidiary (including the Guarantee provided by the Guarantors) of the
Securities shall provide by its terms that it (and all Liens securing the same)
shall be automatically and unconditionally released and discharged upon (i) any
sale, exchange or transfer, to any Person not an Affiliate of the Company, all
or substantially all the assets of, such Restricted Subsidiary, or upon a sale
or transfer of capital stock of such Guarantor (other than a sale or transfer to
an Affiliate of the Issuers) as a result of which such Guarantor ceases to be a
Subsidiary of the Company, or upon the designation of such Guarantor as an
Unrestricted Subsidiary in accordance with the provisions of the Indenture which
transaction is in compliance with the terms of this Indenture or (ii) the
release by the holders of the Indebtedness of the Company described in clause
(a) above or their guarantee by such Restricted Subsidiary (including any deemed
release upon payment in full of all obligations under such Indebtedness), which
resulted in the Securities being guaranteed by such Restricted Subsidiary, at
such time as (A) no other Indebtedness of the Company has been secured or
guaranteed by such Restricted Subsidiary or (B) the holders of all such other
Indebtedness which is guaranteed by such Restricted Subsidiary also release
their guarantee by such Restricted Subsidiary (including any deemed release upon
payment in full of all obligations under such Indebtedness).

            SECTION 4.20. Amendments to Mezzanine Financing.

            The terms of the Mezzanine Financing shall not be amended in a
manner adverse to the Holders.

            SECTION 4.21. Waiver of Compliance With Certain Covenants. The
Issuers may omit in any particular instance to comply with any covenant or
condition set forth in Sections 4.3 and 4.8 through 4.20 if, before or after the
time for such compliance, the holders of not less than a majority in aggregate
principal amount of the Securities at the time outstanding shall, by act of such
holders, waive such compliance in such instance with such covenant or provision,
but no such waiver shall extend to or affect such covenant or condition except
to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the

                                       68
<PAGE>
Issuers and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.

                              SUCCESSOR CORPORATION

            SECTION 5.1. Limitation on Merger, Sale or Consolidation.

            The Company will not consolidate with or merge with or into another
Person, or sell, lease, convey, transfer or otherwise dispose of all or
substantially all of its properties and assets (computed on a consolidated
basis), whether in a single transaction or a series of related transactions, to
another Person or group of affiliated Persons, and the Company will not permit
any Restricted Subsidiary to enter into any such transaction or series of
transactions which would result in a sale, lease, conveyance, transfer or other
disposition of all or substantially all of the properties and assets of the
Company on a consolidated basis, unless (i) either (a) the Company is the
continuing entity or (b) the resulting, surviving or transferee entity is an
entity organized under the laws of the United States, any state thereof or the
District of Columbia and expressly assumes by supplemental indenture all of the
obligations of the Company in connection with the Securities, this Indenture and
the Registration Rights Agreement, as the case may be, and the Securities, this
Indenture and the Registration Rights Agreement will remain in full force and
effect as so supplemented (and any Guarantee shall be confirmed as applied to
the surviving entity's obligations); (ii) no Default or Event of Default shall
exist or shall occur immediately after giving effect on a pro forma basis (and
treating any Indebtedness not previously an obligation of the Company or any of
its Restricted Subsidiaries which becomes the obligation of the Company or any
of its Restricted Subsidiaries as a result of such transaction as having been
incurred at the time of such transaction) to such transaction; (iii) immediately
before and immediately after giving effect to such transaction on a pro forma
basis (on the assumption that the transaction occurred on the first day of the
four-quarter period for which financial statements are available ending
immediately prior to the consummation of such transaction with the appropriate
adjustments with respect to the transaction being included in such pro forma
calculation), either the Company or resulting surviving or transferee entity
would immediately thereafter be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Annual Operating Cash Flow Ratio provision set
forth in the second paragraph of Section 4.11 or such Annual Operating Cash Flow
Ratio would be lower than such ratio immediately prior to such transaction; (iv)
at the time of the transaction each Issuer, unless it is the other party to the
transaction described above, will have by supplemental indenture confirmed that
it remains a co-obligor under this Indenture and the Securities; (v) at the time
of the transaction each Guarantor, if any, unless it is the other party to the
transaction described above, in which case Section 5.1(i)(b) shall apply, will
have by supplemental indenture confirmed that its Guarantee shall apply to such
Person's obligations under this Indenture and the Securities; and (vi) at the
time of the transaction the Company or the resulting surviving or transferee
entity will have delivered, or caused to be delivered, to the Trustee, in form
and substance reasonably satisfactory to the Trustee, an officers' certificate
and an opinion of counsel, each to the effect that such consolidation, merger,
transfer, sale, assignment, conveyance, transfer, lease or other transaction and
the supplemental indenture in respect thereof comply with this Indenture and
that all conditions precedent therein provided for relating to such transaction
have been complied with.

            Notwithstanding the foregoing, any Restricted Subsidiary may merge
with and into any other Restricted Subsidiary or the Company.

            Centennial will not, in a single transaction or through a series of
related transactions, consolidate with or merge with or into any other Person
(other than the Company or any Guarantor) or sell, assign, convey, transfer,
lease or otherwise dispose of all or substantially all of its properties and
assets to any Person or group of Persons (other than the Company or any
Guarantor) unless at the time and after giving effect thereto (i) either (a)
Centennial will be the continuing corporation or (b) the Person (if other than
Centennial) formed by such consolidation or into which Centennial is merged or
the Person which acquires by sale, assignment, conveyance, transfer, lease or
disposition all or substantially all of the properties and assets of Centennial
on a Consolidated basis will be a corporation duly organized and validly
existing under the laws of the United States of America, any state thereof or
the District of Columbia and such Person expressly assumes, by a supplemental
indenture, in a form reasonably satisfactory to the Trustee, all the obligations
of Centennial under the Securities and this Indenture and the Registration
Rights Agreement and such Security, Indenture and Registration Rights Agreement
will remain in full force and effect; (ii) immediately before and immediately
after giving effect to such transaction on a pro forma basis, no Default or
Event of Default will have occurred and be continuing; and (iii) at the time of
the transaction Centennial or the surviving entity will have delivered, or
caused to be delivered, to the Trustee, in form and substance reasonably
satisfactory to the Trustee, an officers' certificate and an opinion of counsel,
each to the effect that such consolidation, merger, transfer, sale, assignment,
conveyance, lease or other transaction and the supplemental indenture in respect
thereof comply with this Indenture and that all conditions precedent therein
provided for relating to such transaction have been complied with. In the event
that the Company shall merge or consolidate with or into Centennial, the
provisions of the first paragraph of this Section are also required to be
satisfied.

            SECTION 5.2. Successor Corporation Substituted.

            Upon any consolidation or merger or any transfer (other than a
lease) of all or substantially all of the assets of the Company or Centennial,
as the case may be in accordance with the foregoing, the successor corporation
formed by such consolidation or into which the Company or Centennial, as the
case may be, is merged or to which such transfer is made, shall succeed to, and
be substituted for, and may exercise every right and power of, the Company or
Centennial, as the case may be, under this Indenture with the same effect as if
such successor entity had been named herein as the Company or Centennial, as the
case may be, and the Company or Centennial, as the case may be (except in
connection with a transfer that results in the transfer of assets constituting
or accounting for less than 95% of the consolidated assets (as of the last
balance sheet available), revenues, or Annual Operating Cash Flow of the Company
or Centennial, as the case may be (as of the last twelve month period for which
financial statements are available)), shall be released from the obligations
under the Securities and this Indenture.

            SECTION 6.2. Acceleration of Maturity Date; Rescission and
Annulment.

            If an Event of Default occurs and is continuing (other than an Event
of Default specified in Sections 6.1(4) and (5), then in every such case, unless
the principal of all of the Securities shall have already become due and
payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities then outstanding, by notice in writing to the
Company (and to the Trustee if given by Holders) (an "Acceleration Notice"), may
declare all principal of the Securities (or the Change of Control Purchase Price
if the Event of Default includes failure to pay the Change of Control Purchase
Price), determined as set forth below, including in each case accrued interest
thereon to be due and payable immediately; provided that so long as the Credit
Facility shall be in full force and effect, if an Event of Default shall have
occurred and be continuing (other than as specified in clause (4) or (5) with
respect to Centennial, the Company, the Initial Guarantor or any Significant
Restricted Subsidiary), any such acceleration shall not be effective until the
earlier to occur of (x) five Business Days following delivery of a written
notice of such acceleration of the Securities to the agent under the Credit
Facility and (y) the acceleration of any Indebtedness under the Credit Facility.
If an Event of Default specified in clauses (4) and (5) above relating to
Centennial, the Company, the Initial Guarantor or any Restricted Subsidiary
occurs, all principal and accrued interest thereon will be immediately due and
payable on all outstanding Securities without any declaration or other act on
the part of Trustee or the Holders.

            At any time after such a declaration of acceleration being made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article VI, the Holders of a
majority in aggregate principal amount of then outstanding Securities, by
written notice to the Company and the Trustee, may rescind, on behalf of all
Holders, any such declaration of acceleration if:

                  (A) the Issuers have paid or deposited with the Trustee cash
            sufficient to pay (A) all overdue interest on all Securities, (B)
            the principal of (and premium, if any, applicable to any Securities
            which would become due otherwise than by such declaration of
            acceleration, and interest thereon at the rate borne by the
            Securities, (C) to the extent that payment of such interest is
            lawful, interest upon overdue interest at the rate borne by the
            Securities, (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

                  (B) all Events of Default, other than the non-payment of the
            principal of, premium, if any, and interest on Securities which have
            become due solely by such declaration of acceleration, have been
            cured or waived as provided in Section 6.12, including, if
            applicable, any Event of Default relating to the covenants contained
            in Section 11.1.

Notwithstanding the previous sentence of this Section 6.2, no waiver shall be
effective against any Holder for any Event of Default or event which with notice
or lapse of time or both would be an Event of Default with respect to any
covenant or provision which cannot be modified or amended without the consent of
the Holder of each outstanding Security affected thereby, unless

                                       73
<PAGE>
all such affected Holders agree, in writing, to waive such Event of Default or
other event. No such waiver shall cure or waive any subsequent default or impair
any right consequent thereon.

            SECTION 6.3. Collection of Indebtedness and Suits for Enforcement by
Trustee.

            The Issuers covenant that if an Event of Default in payment of
principal, premium, or interest specified in clause (1) or (2) of Section 6.1
occurs and is continuing, the Issuers shall, upon demand of the Trustee, pay to
it, for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal, premium (if any), interest and
Additional 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 and Additional Interest, if any, at the rate
borne by the Securities, and, in addition thereto, such further amount as shall
be sufficient to cover the reasonable costs and expenses of collection,
including compensation to, and expenses, disbursements and advances of the
Trustee, its agents and counsel.

            If the Issuers fail to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust in favor of the
Holders, 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 Issuers or any other obligor upon the
Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Issuers or any other obligor
upon the Securities, wherever situated.

            If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective 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 6.4. 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 Issuers or any other obligor upon the
Securities or the property of the Issuers 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 Issuers for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise, to take any and
all actions under the TIA, including (1) to file and prove a claim for the whole
amount of principal (and premium, if any), interest and Additional Interest, if
any, owing and unpaid in respect of the Securities and to file such other papers
or documents 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 agent and counsel) and of the
Holders allowed in such judicial proceeding, and (2) to collect and receive any
moneys or other property payable or deliverable on any such claims and to
distribute the same; and any Custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar

                                       74
<PAGE>
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 7.7.

            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.

            SECTION 6.5. 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 in favor of the Holders, and any
recovery of judgment shall, after provision for the payment of compensation to,
and 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 6.6. Priorities.

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

            FIRST:          To the Trustee in payment of all amounts due
                            pursuant to Section 7.7;

            SECOND:         To the Holders in payment of the amounts then due
                            and unpaid for principal of, premium (if any),
                            interest and Additional Interest, if any, 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, premium (if any) and
                            interest, respectively; and

            THIRD:          To the Issuers.

            SECTION 6.7. Limitation on Suits.

            No Holder of any Security shall have any right to order or direct
the Trustee 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 (A) such Holder has previously given written
notice to the Trustee of a continuing Event of Default; (B) the

                                       75
<PAGE>
Holders of not less than 25% in aggregate principal amount of then outstanding
Securities 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; (C) such Holder or Holders have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities to be incurred
or reasonably probable to be incurred in compliance with such request; (D) the
Trustee for 15 days after its receipt of such notice, request and offer of
indemnity has failed to institute any such proceeding; and (E) no direction
inconsistent with such written request has been given to the Trustee during such
15-day period by the Holders of a majority in principal amount of the
outstanding Securities; it being understood and intended that no one or more
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 Holders, or to obtain or to seek to obtain priority or preference
over any other Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all the
Holders.

            SECTION 6.8. Unconditional Right of Holders to Receive Principal,
Premium, Interest and Additional Interest.

            Notwithstanding any other provision of 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 accrued interest
and Additional Interest (if any) on, such Security on the Maturity Date of such
payments as expressed in such Security (in the case of redemption, the
Redemption Price on the applicable Redemption Date, in the case of the Change of
Control Purchase Price, on the applicable Change of Control Purchase Date, and
in the case of an Asset Sale Offer, the Asset Sale Offer Price on the Asset Sale
Purchase Date), and to institute suit for the enforcement of any such payment
after such respective dates, and such rights shall not be impaired without the
consent of such Holder.

            SECTION 6.9. Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in Section 2.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

            SECTION 6.10. Delay or Omission Not Waiver.

            No delay or omission by the Trustee or by any Holder of any Security
to exercise any right or remedy arising upon any Event of Default shall impair
the exercise of any such right or remedy or constitute a waiver of any such
Event of Default. Every right and remedy given by this Article VI 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.

                                       76
<PAGE>
            SECTION 6.11. Control by Holders.

            The Holder or Holders of a majority in aggregate principal amount of
then outstanding Securities will have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred upon the Trustee, 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 not taking part in such direction, (3) the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, (4) the Trustee may require indemnification to
its satisfaction before taking any action in accordance with such direction and
(5) the Trustee shall not be liable with respect to any action so taken in good
faith.

            SECTION 6.12. Waiver of Past Default.

            Subject to Section 6.8, the Holder or Holders of not less than a
majority in aggregate principal amount of the outstanding Securities may, on
behalf of all Holders, prior to the declaration of the acceleration of the
maturity of the Securities, waive any past default hereunder and its
consequences, except a default (A) in the payment of the principal of, premium,
if any, or interest on, any Security as specified in clauses (1) and (2) of
Section 6.1, or (B) in respect of a covenant or provision hereof which, under
Article IX, cannot be modified or amended without the consent of the Holder of
each outstanding Security 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 the exercise of any right arising therefrom.

            SECTION 6.13. 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 to be taken by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 6.13 shall not apply to any suit instituted
by the Issuers, 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
aggregate principal amount of the outstanding Securities, or to any suit
instituted by any Holder for enforcement of the payment of principal of, or
premium (if any) or interest on, any Security on or after the Maturity Date
expressed in such Security (including, in the case of redemption, on or after
the Redemption Date).

                                       77
<PAGE>
            SECTION 6.14. 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 case, subject to any
determination in such proceeding, the Issuers, 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.

                                  Article VII

                                     TRUSTEE

            The Trustee hereby accepts the trust imposed upon it by this
Indenture and covenants and agrees to perform the same, as herein expressed.

            SECTION 7.1. Duties of Trustee.

            (a) If a Default or 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 his own affairs.

            (b) Except during the continuance of a Default or an Event of
Default:

                  (A) The Trustee need perform only those duties as are
            specifically set forth in this Indenture and no others, and no
            covenants or obligations shall be implied in or read into this
            Indenture.

                  (B) 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. However, the Trustee shall examine the
            certificates and opinions to determine whether or not they conform
            to the requirements of this Indenture.

            (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (A) This paragraph does not limit the effect of paragraph (b)
            of this Section 7.1.

                  (B) The Trustee shall not be liable for any error of judgment
            made in good faith by a Trust Officer, unless it is proved that the
            Trustee was negligent in ascertaining the pertinent facts.

                                       78
<PAGE>
                  (C) The Trustee shall not be liable with respect to any action
            it takes or omits to take in good faith in accordance with a
            direction received by it pursuant to Section 6.11.

            (d) 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.

            (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section 7.1
and shall extend to the Registrar and Paying Agent.

            (f) The Trustee shall not be liable for interest on any assets
received by it except as the Trustee may agree in writing with the Issuers.
Assets held in trust by the Trustee need not be segregated from other assets
except to the extent required by law.

            SECTION 7.2. Rights of Trustee.

            Subject to Section 7.1:

            (a) The Trustee may rely on any document believed by it to be
genuine and to have been signed or presented by the proper Person. The Trustee
need not investigate any fact or matter stated in the document.

            (b) Before the Trustee acts or refrains from acting, it may consult
with counsel and may require an Officers' Certificate or an Opinion of Counsel,
which shall conform to Sections 13.4 and 13.5. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on such
certificate or advice of counsel.

            (c) The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

            (d) The Trustee will not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers conferred upon it by this Indenture.

            (e) The Trustee will not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, notice, request, direction, consent, order, bond, debenture, 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 Issuers
personally or by agent or attorney.

            (f) The Trustee will be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee

                                       79
<PAGE>
reasonable security or indemnity against the costs, expenses and liabilities
which may be incurred therein or thereby.

            (g) Unless otherwise specifically provided for in this Indenture,
any demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

            (h) The Trustee shall have no duty to inquire as to the performance
of the covenants in Article IV hereof. In addition, the Trustee shall not be
deemed to have knowledge of any Default or Event of Default hereunder except (i)
any Event of Default occurring pursuant to Section 6.1(1) or 6.1(2), or (ii) any
Default or Event of Default of which the Trustee shall have received
notification or obtained knowledge. In the absence of such actual knowledge or
notice, the Trustee may conclusively assume that no default has occurred and is
continuing under this Indenture.

            (i) The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty unless so specified herein.

            SECTION 7.3. Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or any of
the Company's Subsidiaries, or their respective Affiliates with the same rights
it would have if it were not Trustee. Any Agent may do the same with like
rights. However, the Trustee must comply with Sections 7.10 and 7.11.

            SECTION 7.4. Trustee's Disclaimer.

            The Trustee makes no representation as to the validity, adequacy or
priority of this Indenture or the Securities and it shall not be accountable for
the Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement in the Securities, other than the Trustee's
certificate of authentication, or the use or application of any funds received
by a Paying Agent other than the Trustee.

            SECTION 7.5. Notice of Default.

            If a Default or an Event of Default occurs and is continuing and if
it is actually known to the Trustee, the Trustee shall mail to each
Securityholder notice of the uncured Default or Event of Default within 90 days
after such Default or Event of Default occurs. Except in the case of a Default
or an Event of Default in payment of principal (or premium, if any) of, or
interest on, any Security (including the payment of the Change of Control
Purchase Price on the Change of Control Purchase Date, the payment of the
Redemption Price on the Redemption Date and the payment of the Asset Sale Offer
Price on the Asset Sale Purchase Date), the Trustee may withhold the notice if
and so long as a Trust Officer in good faith determines that withholding the
notice is in the interest of the Securityholders.

                                       80
<PAGE>
            SECTION 7.6. Reports by Trustee to Holders.

            Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, the Trustee shall, if required by law, mail to each
Securityholder a brief report dated as of such May 15 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and
313(c).

            The Issuers shall promptly notify the Trustee in writing if the
Securities become listed on any stock exchange or automatic quotation system.

            A copy of each report at the time of its mailing to Securityholders
shall be mailed to the Issuers and filed with the SEC and each stock exchange,
if any, on which the Securities are listed.

            SECTION 7.7. Compensation and Indemnity.

            The Issuers agree to pay to the Trustee from time to time reasonable
compensation for its services. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Issuers shall
reimburse the Trustee upon request for all reasonable disbursements, expenses
and advances incurred or made by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents, accountants,
experts and counsel.

            The Issuers agree to indemnify the Trustee (in its capacity as
Trustee) and each of its officers, directors, attorneys-in-fact and agents for,
and hold it harmless against, any claim, demand, expense (including but not
limited to reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel), loss or liability incurred by it without negligence or
willful misconduct on its part, arising out of or in connection with the
administration of this trust and its rights or duties hereunder including the
reasonable costs and expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of its powers or duties
hereunder. The Trustee shall notify the Issuers promptly of any claim asserted
against the Trustee for which it may seek indemnity. The Issuers need not
reimburse any expense or indemnify against any loss or liability to the extent
incurred by the Trustee through its negligence or willful misconduct.

            To secure the Issuers' payment obligations in this Section 7.7., the
Trustee shall have a lien prior to the Securities on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal and premium, if any, of or interest on particular
Securities.

            When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

            The Issuers' obligations under this Section 7.7 and any lien arising
hereunder shall survive the resignation or removal of the Trustee, the discharge
of the Issuers' obligations pursuant to Article VIII of this Indenture and any
rejection or termination of this Indenture under any Bankruptcy Law.

                                       81
<PAGE>
            SECTION 7.8. Replacement of Trustee.

            The Trustee may resign by so notifying the Issuers in writing. The
Holder or Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Issuers and the Trustee in
writing and may appoint a successor trustee with the Issuers' consent. The
Issuers may remove the Trustee if:

            (a) the Trustee fails to comply with Section 7.10;

            (b) the Trustee is adjudged bankrupt or insolvent;

            (c) a receiver, Custodian, or other public officer takes charge of
      the Trustee or its property; or

            (d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of
Trustee for any reason, the Issuers shall promptly appoint a successor Trustee.
Within one year after the successor Trustee takes office, the Holder or Holders
of a majority in principal amount of the Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Issuers. A successor
Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Issuers. Immediately after that and provided that all sums
owing to the trustee provided for in Section 7.7 have been paid, the retiring
Trustee shall transfer all property held by it as trustee to the successor
Trustee, subject to the lien provided in Section 7.7, the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture. A
successor Trustee shall mail notice of its succession to each Holder.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuers or the
Holder or Holders of at least 10% in principal amount of the outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

            Notwithstanding replacement of the Trustee pursuant to this Section
7.8, the Issuers' obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

            SECTION 7.9. Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or

further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

purporting to be the person or persons so designated. The persons and telephone
numbers for call-backs may be changed only in a writing actually received and
acknowledged by the Trustee. The parties to this Indenture acknowledge that such
security procedure is commercially reasonable.

            (b) It is understood that the Trustee and the beneficiary's bank in
any funds transfer may rely solely upon any account numbers or similar
identifying number provided by either of the other parties hereto to identify
(i) the beneficiary, (ii) the beneficiary's bank, or (iii) an order it executes
using any such identifying number, even where its use may result in a person
other than the beneficiary being paid, or the transfer of funds to a bank other
than the beneficiary's bank or an intermediary bank designated.

            (c) All money held by the Trustee in any of the accounts or funds
established pursuant hereto shall be invested in Marketable U.S. Securities upon
receipt of a Company Request. In the absence of such Company Request, the
Trustee shall invest in those items described in clause (vi) of the definition
of Marketable U.S. Securities. The Trustee may act as principal or agent in the
acquisition or disposition of investments. The Trustee shall not be responsible
for any loss of any investment made in accordance herewith.

                                  Article VIII

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

            SECTION 8.1. Option to Effect Legal Defeasance or Covenant
Defeasance.

            The Company may, at its option and at any time, elect to have
Section 8.2 or Section 8.3 applied to all outstanding Securities upon compliance
with the conditions set forth below in this Article VIII.

                                       83
<PAGE>
            SECTION 8.2. Legal Defeasance and Discharge.

            Upon the Company's exercise under Section 8.1 of the option
applicable to this Section 8.2, the Issuers, any Guarantor and any other obligor
upon the Securities shall be deemed to have been discharged from their
obligations with respect to all outstanding Securities on the date the
conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For
this purpose, such Legal Defeasance means that the Issuers, any Guarantor and
any other obligor upon the securities shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Securities,
which shall thereafter be deemed to be "outstanding" only for the purposes of
Section 8.5 and the other Sections of this Indenture referred to in (a) and (b)
below, and to have satisfied all its other obligations under such Securities and
this Indenture (and the Trustee, on demand of and at the expense of the Issuers,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder: (a) the rights of Holders of outstanding Securities to receive solely
from the trust fund described in Section 8.4, and as more fully set forth in
such Section 8.4, payments in respect of the principal of, premium, if any, and
interest on such Securities when such payments are due, (b) the Issuers'
obligations with respect to such Securities under Sections 2.4, 2.7, 2.10, 2.13,
2.14, 2.15 and 4.2, (c) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and the Issuers' obligations in connection therewith and (d)
this Article VIII. Subject to compliance with this Article VIII, the Company may
exercise its option under this Section 8.2 notwithstanding the prior exercise of
its option under Section 8.3 with respect to the Securities.

            SECTION 8.3. Covenant Defeasance.

            Upon the Company's exercise under Section 8.1 of the option
applicable to this Section 8.3, the Issuers shall be released from their
obligations under the covenants contained in Sections 4.3, 4.5, 4.6, 4.7, 4.8,
4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.17, 4.18, 4.19, 4.20, and Article V (other
than the obligation of any successor to assume the obligations of the Issuers
hereunder) with respect to the outstanding Securities on and after the date the
conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"),
and the Securities shall thereafter be deemed not "outstanding" for the purposes
of any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder. For this
purpose, such Covenant Defeasance means that, with respect to the outstanding
Securities, the Issuers need not comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document, but, except as specified above,
the remainder of this Indenture and such Securities shall be unaffected thereby.
If Covenant Defeasance occurs, the events listed in Section 6.1, other than
those described in subsections (1), (2), (4) and (5), shall no longer constitute
Events of Default with respect to the Securities.

            SECTION 8.4. Conditions to Legal or Covenant Defeasance.

            The following shall be the conditions to the application of either
Section 8.2 or Section 8.3 to the outstanding Securities:

                                       84
<PAGE>

            (a) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee satisfying the requirements
      of Section 7.10 who shall agree to comply with the provisions of this
      Article VIII applicable to it) as trust funds in trust for the purpose of
      making the following payments, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of such Securities, U.S.
      Legal Tender, non-callable Government Securities or a combination thereof,
      in such amounts, as in each case will be sufficient, in the opinion of a
      nationally recognized firm of independent public accountants expressed in
      a written certification thereof delivered to the Trustee, to pay and
      discharge and which shall be applied by the Trustee (or other qualifying
      trustee) to pay and discharge the principal of, premium, if any, and
      interest and Additional Interest, if any, on such Securities on the Stated
      Maturity or on the applicable Redemption Date of such principal or
      installment of principal of, premium, if any, or interest on such
      Securities, and the Holders of Securities must have a valid, perfected,
      exclusive security interest in such trust; provided that the Trustee shall
      have been irrevocably instructed to apply such U.S. Legal Tender or
      non-callable Government Securities to said payments with respect to the
      Securities;

            (b) In the case of an election under Section 8.2, the Company shall
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee confirming that (i) the Company has
      received from, or there has been published by, the Internal Revenue
      Service a ruling or (ii) since the date hereof, there has been a change in
      the applicable Federal income tax law, in each case to the effect that,
      and based thereon such Opinion of Counsel shall confirm that, the Holders
      of such Securities will not recognize income, gain or loss for Federal
      income tax purposes as a result of such Legal Defeasance, and will be
      subject to Federal income tax in the same amount, in the same manner and
      at the same times as would have been the case if such Legal Defeasance had
      not occurred;

            (c) In the case of an election under Section 8.3, the Company shall
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to such Trustee confirming that the Holders of such
      Securities will not recognize income, gain or loss for Federal income tax
      purposes as a result of such Covenant Defeasance and will be subject to
      Federal income tax on the same amounts, in the same manner and at the same
      times as would have been the case if such Covenant Defeasance had not
      occurred;

            (d) No Default or Event of Default shall have occurred and be
      continuing on the date of such deposit or, insofar as Section 6.1(4) or
      6.1(5) is concerned, at any time in the period ending on the 91st day
      after the date of such deposit (other than a Default which results from
      the borrowing of amounts to finance the defeasance and which borrowing
      does not result in a breach or violation of, or constitute a default
      under, any other material agreement or instrument to which Centennial, the
      Company or any Restricted Subsidiary is a party or to which it is bound)
      (it being understood that such condition will not be satisfied until the
      expiration of such 91-day period);

            (e) The Company shall have delivered to the Trustee an Opinion of
      Counsel in the United States reasonably acceptable to the Trustee to the
      effect that (assuming that no holder of any Securities would be considered
      an insider of the Company under any

                                       85
<PAGE>

      applicable bankruptcy or insolvency law) after the 91st day following the
      deposit, the trust funds will not be subject to the effect of any
      applicable bankruptcy, insolvency, reorganization or similar laws
      affecting creditors' rights generally;

            (f) such defeasance or covenant defeasance shall not cause the
      Trustee for the Securities to have a conflicting interest for purposes of
      the Trust Indenture Act with respect to any securities of the Issuers or
      any Guarantor;

            (g) such Legal Defeasance or Covenant Defeasance shall not result in
      a breach or violation of, or constitute a default under, this Indenture or
      any other material agreement or instrument to which the Issuers, any
      Guarantor or any of their Subsidiaries is bound;

            (h) the Company shall have delivered to the Trustee an Officers'
      Certificate stating that the deposit was not made by the Company with the
      intent of preferring the Holders of such Securities over any other
      creditors of the Company or with the intent of defeating, hindering,
      delaying or defrauding any other creditors of the Issuers or others; and

            (i) the Company shall have delivered to the Trustee an Officers'
      Certificate and Opinion of Counsel each stating that all conditions
      precedent provided for or relating to either the Legal Defeasance under
      Section 8.2 or the Covenant Defeasance under Section 8.3 (as the case may
      be) have been complied with as contemplated by this Section 8.4.

            SECTION 8.5. Deposited U.S. Legal Tender and Government Securities
to be Held in Trust; Other Miscellaneous Provisions.

            Subject to Section 8.6, all U.S. Legal Tender and Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.5, the
"Trustee") pursuant to Section 8.4 in respect of the outstanding Securities
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent as the Trustee may determine, to the
Holders of such Securities of all sums due and to become due thereon in respect
of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

            SECTION 8.6. Repayment to the Issuers.

            Subject to any applicable escheat or abandoned property laws, any
money deposited with the Trustee or any Paying Agent, or then held by the
Issuers, in trust for the payment of the principal of, premium, if any, or
interest on any Security and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company within sixty (60) days after termination of such two-year
period; and the Holder of such Security shall thereafter look only to the
Issuers for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money shall thereupon cease. The Trustee shall
not be liable to the Issuers or any Holder for interest on funds held by it for
the payment and discharge of the interest, or premium (if any) on or principal

                                       86
<PAGE>

of any of the Securities to any Holder. The Issuers shall not be liable for any
interest on the sums paid to it pursuant to this paragraph and shall not be
regarded as a trustee of such money.

            SECTION 8.7. Reinstatement.

            If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or Government Securities in accordance with Section 8.2 or 8.3, as the
case may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Issuers' obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 8.2
or 8.3 until such time as the Trustee or Paying Agent is permitted to apply such
money in accordance with Sections 8.2 and 8.3, as the case may be; provided,
however, that, if the Issuers make any payment of principal of, premium, if any,
or interest on any Security following the reinstatement of its obligations, the
Issuers shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the cash held by the Trustee or Paying Agent.

                                   ARTICLE IX
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

            SECTION 9.1. Supplemental Indentures Without Consent of Holders.

            Without the consent of any Holder, the Issuers, any Guarantor and
any other obligor under the Securities when authorized by Board Resolutions, and
the Trustee, at any time and from time to time, may enter into one or more
indentures supplemental hereto, in form satisfactory to the Trustee, for any of
the following purposes:

                  (A) to evidence the succession of another Person to
            Centennial, the Company or a Guarantor, and the assumption by any
            such successor of the covenants of Centennial, the Company or such
            Guarantor in this Indenture and in the Securities and in any
            Guarantee in accordance with Section 5.1;

                  (B) to add to the covenants of Centennial, the Company, any
            Guarantor or any other obligor upon the Securities for the benefit
            of the Holders of the Securities or to surrender any right or power
            conferred upon Centennial, the Company or any Guarantor or any other
            obligor upon the Securities, as applicable, in this Indenture, in
            the Securities or in any Guarantee;

                  (C) to cure any ambiguity, or to correct or supplement any
            provision in this Indenture, the Securities or any Guarantee which
            may be defective or inconsistent with any other provision in this
            Indenture, the Securities or any Guarantee or make any other
            provisions with respect to matters or questions arising under this
            Indenture, the Securities or any Guarantee; provided that, in each
            case, such provisions shall not adversely affect the interest of the
            holders of the Securities;

                                       87
<PAGE>

                  (D) to comply with the requirements of the Commission in order
            to effect or maintain the qualification of this Indenture under the
            Trust Indenture Act;

                  (E) to add a Person as a Guarantor under this Indenture;

                  (F) to evidence and provide the acceptance of the appointment
            of a successor Trustee under this Indenture; or

                  (G) to provide for the issuance of Additional Securities under
            the Indenture; or

                  (H) to mortgage, pledge, hypothecate or grant a security
            interest in favor of the Trustee for the benefit of the holders of
            the Securities as additional security for the payment and
            performance of Centennial's, the Company's and any Guarantor's
            obligations under this Indenture, in any property, or assets,
            including any of which are required to be mortgaged, pledged or
            hypothecated, or in which a security interest is required to be
            granted to the Trustee pursuant to this Indenture or otherwise.

            SECTION 9.2. Amendments, Supplemental Indentures and Waivers With
Consent of Holders.

            Subject to Section 6.8, with the consent of the Holders of not less
than a majority in aggregate principal amount of then outstanding Securities,
including Additional Securities, if any, by written act of said Holders
delivered to the Issuers and the Trustee, the Issuers, the Guarantors and any
other obligor under the Securities when authorized by Board Resolutions, and the
Trustee may amend or supplement this Indenture or the Securities or enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or the Securities or of modifying in any manner the rights of the
Holders under this Indenture or the Securities. Subject to Section 6.8, the
Holder or Holders of not less than a majority, in principal amount of then
outstanding Securities, including Additional Securities, if any, may waive
compliance by the Issuers with any provision of this Indenture or the
Securities. Notwithstanding any of the above, however, no such amendment,
supplemental indenture or waiver shall, without the consent of the Holder of
each outstanding Security affected thereby:

                  (A) change the Stated Maturity of, or the Change of Control
            Purchase Date or the Asset Sale Offer Period on, or change to an
            earlier date any Redemption Date of, any Note, or reduce the
            principal amount thereof or the rate (or extend the time for
            payment) of interest or Additional Interest, if any, thereon or any
            premium payable upon the redemption thereof, or change the place of
            payment where, or the coin or currency in which, any Note or any
            premium or the interest thereon is payable, or impair the right to
            institute suit for the enforcement of any such payment on or after
            the Stated Maturity thereof (or, in the case of redemption, on or
            after the Redemption Date), or reduce the Change of Control Purchase
            Price or the Asset Sale Offer Price or alter the redemption
            provisions or

                                       88
<PAGE>

            the provisions of Article XI, including, in each case, amending,
            changing or modifying any definitions related thereto, but only to
            the extent such definitions relate thereto, in a manner adverse to
            the Holders;

                  (B) reduce the percentage in principal amount of the
            outstanding Securities, the consent of whose Holders is required for
            any such amendment, supplemental indenture or waiver provided for in
            this Indenture;

                  (C) modify any of the waiver provisions, except to increase
            any required percentage or to provide that certain other provisions
            of this Indenture cannot be modified or waived without the consent
            of the Holder of each outstanding Security affected thereby;

                  (D) except as otherwise permitted under Section 5.1 consent to
            the assignment or transfer by Centennial, the Company or any
            Guarantor of any of its rights and obligations under this Indenture;
            or

                  (E) amend or modify any of the provisions of this Indenture
            relating to the Guarantee in any manner adverse to the holders of
            the Securities.

            It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

            After an amendment, supplement or waiver under this Section 9.2
becomes effective, the Issuers shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuers to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture or
waiver.

            After an amendment, supplement or waiver under this Section 9.2 or
Section 9.4 becomes effective, it shall bind each Holder.

            In connection with any amendment, supplement or waiver under this
Article IX, the Issuers may, but shall not be obligated to, offer to any Holder
who consents to such amendment, supplement or waiver, or to all Holders,
consideration for such Holder's consent to such amendment, supplement or waiver.

            SECTION 9.3. Compliance With TIA.

            Every amendment, waiver or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.

            SECTION 9.4. Revocation and Effect of Consents.

            Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if

                                       89
<PAGE>

notation of the consent is not made on any Security. However, any such Holder or
subsequent Holder may revoke the consent as to his Security or portion of his
Security by written notice to the Issuers or the Person designated by the
Issuers as the Person to whom consents should be sent if such revocation is
received by the Issuers or such Person before the date on which the Trustee
receives an Officers' Certificate certifying that the Holders of the requisite
principal amount of Securities have consented (and not theretofore revoked such
consent) to the amendment, supplement or waiver.

            The Issuers may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which record date shall be the date so fixed by the
Issuers notwithstanding the provisions of the TIA. If a record date is fixed,
then notwithstanding the last sentence of the immediately preceding paragraph,
those Persons who were Holders at such record date, and only those Persons (or
their duly designated proxies), shall be entitled to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date. No such consent shall be valid or effective for more than 90 days
after such record date.

            After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (8) of Section 9.2, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security; provided that any such waiver
shall not impair or affect the right of any Holder to receive payment of
principal and premium of and interest on a Security, on or after the respective
dates set for such amounts to become due and payable expressed in such Security,
or to bring suit for the enforcement of any such payment on or after such
respective dates.

            SECTION 9.5. Notation on or Exchange of Securities.

            If an amendment, supplement or waiver changes the terms of a
Security, the Trustee may require the Holder of the Security to deliver it to
the Trustee or require the Holder to put an appropriate notation on the
Security. The Trustee may place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Issuers or
the Trustee so determines, the Issuers in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms. Any failure to make the appropriate notation or to issue a new Security
shall not affect the validity of such amendment, supplement or waiver.

            SECTION 9.6. Trustee to Sign Amendments, Etc.

            The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article IX; provided that the Trustee may, but shall
not be obligated to, execute any such amendment, supplement or waiver which
affects the Trustee's own rights, duties or immunities under this Indenture. The
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of any amendment,

                                    GUARANTEE

            SECTION 10.1. Guarantee. The Guarantors, jointly and severally,
hereby fully, unconditionally and irrevocably guarantee as primary obligors and
not merely as a sureties, the obligations of the Company under the Securities
and this Indenture, and guarantee to each Holder of a Security authenticated and
delivered by the Trustee in accordance with the terms hereof, and to the Trustee
on behalf of such Holder, that (a) the Company will make payment of the
principal of and interest (including Additional Interest, if any) on the
Securities will be paid in full when due, whether at the Maturity Date, by
acceleration, redemption or otherwise (including, without limitation, the amount
that would become due but for the operation of the automatic stay under Section
362(a) of the Bankruptcy Law), together with interest on the overdue principal,
if any, and interest on any overdue interest, to the extent lawful, and all
other obligations of the Issuers to the Holders or the Trustee hereunder or
thereunder, including obligations arising under Articles III and VII hereof,
will be paid in full or performed, all in accordance with the terms hereof and
thereof and (b) the full performance, within applicable grace periods, of all
other obligations of the Company under this Indenture and the Securities which
may be extended or renewed, in whole or in part, without notice or further
assent from such Guarantor and that such Subsidiary Guarantor will remain bound
under this Article X, notwithstanding any extension or renewal.

            The Guarantor hereby agree that its obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Securities or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder with respect to any provisions hereof or
thereof, the recovery of any judgment against the Issuers, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor.

            The Guarantor hereby waives (to the extent permitted by law) the
benefits of diligence, presentment, demand for payment, filing of claims with a
court in the event of insolvency or bankruptcy of the Company, any right to
require a proceeding first against the Issuers or any other Person, protest,
notice and all demands whatsoever and covenant that the Guarantee of such
Guarantor shall not be discharged as to any Security except by complete
performance of the obligations contained in such Security, this Indenture and
such Guarantee. The Guarantor acknowledges that the Guarantee is a guarantee of
payment and not of collection.

            The Guarantor hereby agree that, in the event of a default in
payment of principal or interest, including contingent interest, if any, on such
Security, whether at the Maturity Date of the Security, by acceleration,
redemption, purchase or otherwise, legal proceedings may be instituted by the
Trustee on behalf of or by the Holder of such Security, subject to the terms and
conditions set forth in this Indenture, directly against each of the Guarantor
to enforce such Guarantor's Guarantee without first proceeding against the
Company or any other Guarantor, if any. The Guarantor agrees that if, after the
occurrence and during the continuance of an Event of Default, the Trustee or any
of the Holders are prevented by applicable law from exercising their respective
rights to accelerate the maturity of the Securities, to collect interest on the
Securities, or to enforce or exercise any other right or remedy with respect to
the Securities, such Guarantor shall pay to the Trustee for the account of the
Holder, upon demand therefor, the amount that

                                       91
<PAGE>

would otherwise have been due and payable had such rights and remedies been
permitted to be exercised by the Trustee or any of the Holders.

            If any Holder or the Trustee is required by any court or otherwise
to return to the Issuers or any Guarantor, or any custodian, trustee, liquidator
or other similar official acting in relation to either the Issuers or any
Guarantor, any amount paid by any of them to the Trustee or such Holder, the
Guarantee of the Guarantor, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Guarantor further agrees that as
between each Guarantor, on the one hand, and the Holders and the Trustee, on the
other hand, (x) subject to this Article X, the maturity of the obligations
guaranteed hereby may be accelerated as provided in Article VI hereof for the
purposes of the Guarantee of such Guarantor notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligation
as provided in Article VI hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by each Guarantor for the
purpose of the Guarantee of such Guarantor.

            The Guarantee shall remain in full force and effect and continue to
be effective should any petition be filed by or against the Company for
liquidation, dissolution or reorganization, should the Company become insolvent
or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Issuers' assets, and
shall, to the fullest extent permitted by law, continue to be effective or be
reinstated, as the case may be, if at any time payment and performance of the
Securities are, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee on the Securities, whether
as a "voidable preference," "fraudulent transfer" or otherwise, all as though
such payment or performance had not been made. In the event that any payment or
any part thereof, is rescinded, reduced, restored or returned, for the purposes
of the amounts due under the Guarantee, the Securities shall, to the fullest
extent permitted by law, be reinstated and deemed reduced only by such amount
paid and not so rescinded, reduced, restored or returned.

            Notwithstanding anything to contrary herein, nothing in this Section
X shall constitute a guarantee by any Guarantor of any obligations of Centennial
under the Securities and this Indenture.

            SECTION 10.2. Future Guarantors. Any Person that becomes a
Guarantor, after the date of this Indenture, shall (a) execute and deliver to
the Trustee a supplement to this Indenture in accordance with the provisions of
Article IX of this Indenture, pursuant to which such Person shall guarantee the
Securities and the obligations of the Issuers thereunder and hereunder, on the
same basis as the Guarantor on the date hereof and (b) deliver promptly to the
Trustee (i) the supplemental indenture executed by such Person referred to in
(a) above, and (ii) an Opinion of Counsel reasonably satisfactory to such
Trustee to the effect that such supplemental indenture has been duly executed
and delivered by such Person and is in compliance with the terms of this
Indenture. Upon the execution of any such supplemental indenture, the
obligations of the Guarantors and any such Person under their respective
Guarantee shall become joint and several and each reference to the "Guarantor"
in this Indenture shall be deemed to refer to all Guarantors, including such
Person.

            SECTION 10.3. Limitation of Guarantors' Liability. Each Guarantor,
and by its

                                       92
<PAGE>

acceptance hereof, each Holder confirms that it is the intention of all such
parties that the Guarantee by the Guarantor pursuant to its Guarantee not
constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy
Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act
or any similar federal or state law or the provisions of its local law relating
to fraudulent transfer or conveyance. To effectuate the foregoing intention, the
Holders and the Guarantor hereby irrevocably agree that the obligations of such
Guarantor under its Guarantee shall be limited to the maximum amount that will
not, after giving effect to all other contingent and fixed liabilities of such
Guarantor, result in the obligations of such Guarantor under its Guarantee
constituting such fraudulent transfer or conveyance. In case any provision of
any Guarantee shall be invalid, illegal or unenforceable, the validity,
legality, and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

            SECTION 10.4. Subrogation. The Guarantor shall be subrogated to all
rights of Holders against the Company in respect of any amounts paid by any
Guarantor pursuant to the provisions of Section 10.1; provided, however, that,
if an Event of Default has occurred and is continuing, no Guarantor shall be
entitled to enforce or receive any payments arising out of, or based upon, such
right of subrogation until all amounts then due and payable by the Issuers under
this Indenture or the Securities shall have been paid in full.

            SECTION 10.5. Benefits Acknowledged. The Guarantor acknowledges that
it will receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture and that its Guarantee and waivers pursuant to
its Guarantee are knowingly made in contemplation of such benefits.

            SECTION 10.6. Contribution. The Guarantor that makes a payment under
its Guarantee shall be entitled upon payment in full of all its obligations
under the Guarantee to a contribution from each other Guarantor, if any, in an
amount equal to such other Guarantor's pro rata portion of such payment based on
the respective net assets of all the Guarantors at the time of such payment
determined in accordance with GAAP.

                                   ARTICLE XI
                           RIGHT TO REQUIRE REPURCHASE

            SECTION 11.1. Repurchase of Securities at Option of the Holder Upon
a Change of Control.

            (a) In the event that a Change of Control has occurred, unless all
Securities have been called for redemption, each Holder of Securities will have
the right, at such Holder's option, pursuant to an irrevocable and unconditional
offer by the Issuers (the "Change of Control Offer"), to require the Issuers to
repurchase all or any part (equal to $1,000 principal amount or an integral
multiple thereof) of such Holder's Securities, on a date (the "Change of Control
Purchase Date") that is no later than 45 Business Days after the occurrence of
such Change of Control at a cash price (the "Change of Control Purchase Price")
equal to 101% of the aggregate principal amount thereof, together with any
accrued and unpaid interest to the Change of Control Purchase Date. The Change
of Control Offer shall be made within 30 Business Days following a Change of
Control and shall remain open for 20 Business Days following its commencement
(the

                                       93
<PAGE>

"Change of Control Offer Period"). Upon expiration of the Change of Control
Offer Period, the Issuers shall purchase all Securities properly tendered in
response to the Change of Control Offer.

            (b) In the event that, pursuant to this Section 11.1, the Issuers
shall be required to commence such an offer to purchase Securities (a "Change of
Control Offer"), the Issuers shall follow the procedures set forth in this
Section 11.1 as follows:

                  (A) the Issuers shall provide the Trustee with notice of the
            Change of Control Offer at least 5 Business Days before the
            commencement of any Change of Control Offer; and

                  (B) on or before the commencement of any Change of Control
            Offer, the Issuers or the Trustee (upon the request and at the
            expense of the Issuers) shall send, by first-class mail, a notice to
            each of the Holders, which (to the extent consistent with this
            Indenture) shall govern the terms of the Change of Control Offer and
            shall state:

            (ii) that the Change of Control Offer is being made pursuant to such
      notice and this Section 11.1 and that all Securities, or portions thereof,
      tendered will be accepted for payment;

            (iii) the Change of Control Purchase Price (including the amount of
      accrued and unpaid interest), the Change of Control Purchase Date and the
      Change of Control Put Date (as defined below);

            (iv) that any Security, or portion thereof, not tendered or accepted
      for payment will continue to accrue interest;

            (v) that, unless the Issuers default in depositing cash with the
      Paying Agent in accordance with the last paragraph of this clause (b) or
      such payment is prevented, any Security, or portion thereof, accepted for
      payment pursuant to the Change of Control Offer shall cease to accrue
      interest after the Change of Control Purchase Date;

            (vi) that Holders electing to have a Security, or portion thereof,
      purchased pursuant to a Change of Control Offer will be required to
      surrender the Security, with the form entitled "Option of Holder to Elect
      Purchase" on the reverse of the Security completed, to the Paying Agent
      (which may not for purposes of this Section 11.1, notwithstanding anything
      in this Indenture to the contrary, be the Company or any Affiliate of the
      Company) at the address specified in the notice prior to the close of
      business on the earlier of (a) the third Business Day prior to the Change
      of Control Purchase Date and (b) the third Business Day following the
      expiration of the Change of Control Offer (such earlier date being the
      "Change of Control Put Date");

            (vii) that Holders will be entitled to withdraw their election, in
      whole or in part, if the Paying Agent (which may not for purposes of this
      Section 11.1, notwithstanding anything in this Indenture to the contrary,
      be the Company or any Affiliate of the Company) receives, up to the close
      of business (5:00 p.m. New York Time) on the

                                       94
<PAGE>

      Change of Control Put Date, a telegram, telex, facsimile transmission or
      letter setting forth the name of the Holder, the principal amount of the
      Securities the Holder is withdrawing and a statement that such Holder is
      withdrawing his election to have such principal amount of Securities
      purchased; and

            (viii) a brief description of the events resulting in such Change of
      Control.

            On or before the Change of Control Purchase Date, the Issuers will
(i) accept for payment Securities or portions thereof properly tendered pursuant
to the Change of Control Offer, (ii) deposit with the Paying Agent cash
sufficient to pay the Change of Control Purchase Price (together with accrued
and unpaid interest) of all Securities so tendered and (iii) deliver to the
Trustee Securities so accepted together with an Officers' Certificate listing
the Securities or portions thereof being purchased by the Issuers. The Paying
Agent promptly will deliver to the Holders of Securities so accepted payment in
an amount equal to the Change of Control Purchase Price (together with any
accrued and unpaid interest), and the Trustee will promptly authenticate and
mail or deliver to such Holders a new Security equal in principal amount to any
unpurchased portion of the Security surrendered. Any Securities not so accepted
will be promptly mailed or delivered by the Issuers to the Holder thereof. The
Issuers will announce publicly the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Purchase Date.

            Any Change of Control Offer will be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation 14E
under the Exchange Act and the rules thereunder and all other applicable Federal
and state securities laws and the Issuers may modify a Change of Control Offer
to the extent necessary to effect such compliance.

            Capitalized terms used herein shall have the meaning assigned to
them in the Indenture referred to below unless otherwise indicated.

1.    Interest.

            Centennial Cellular Operating Co. LLC, a Delaware limited liability
company (hereinafter called the "Company," which term includes any successors
under the Indenture hereinafter referred to) and Centennial Communications
Corp., a Delaware corporation (hereinafter called "Centennial," which term
includes any successors under the Indenture hereinafter referred to, and
together with the Company, the "Issuers"), promise to pay interest on the
principal amount of this Security at the rate and in the manner specified below.
Interest will accrue at 10"% per annum and will be payable semi-annually in
arrears in cash on June 15 and December 15 of each year or if any such day is
not a Business Day on the next succeeding Business Day (each an "Interest
Payment Date") commencing December 15, 2003, to Holders of record of the
Securities at the close of business on the immediately preceding June 1 or
December 1, whether or not a Business Day (each, a "Record Date").

            Interest will be computed on the basis of a 360-day year consisting
of twelve 30-day months. Interest shall accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
issuance. To the extent lawful, the Issuers shall pay interest on overdue
principal at the rate of the then applicable interest rate on the Securities;
they shall pay interest on overdue installments of interest (without regard to
any applicable grace periods) at the same rate to the extent lawful.

2.    Method of Payment.

            The Issuers shall pay interest and Additional Interest, if any, on
the Securities (except defaulted interest) to the Persons who are the registered
Holders at the close of business on the Record Date immediately preceding the
Interest Payment Date. Holders must surrender Securities to a Paying Agent to
collect principal payments. Except as provided below, the Issuers shall pay
principal and interest in such coin or currency of the United States of America
as at the time of payment shall be legal tender for payment of public and
private debts ("U.S. Legal Tender"). However, the Issuers may pay principal and
interest by wire transfer of Federal funds, or interest by its check payable in
such U.S. Legal Tender. The Issuers may deliver any such interest payment to the
Paying Agent or the Issuers may mail any such interest payment to a Holder at
the Holder's registered address.

3.    Paying Agent and Registrar.

            Initially, U.S. Bank National Association (the "Trustee") will act
as Paying Agent and Registrar. The Issuers may change any Paying Agent,
Registrar or co-Registrar without

                                     A-1-6
<PAGE>
notice to the Holders. The Issuers or any of their Subsidiaries may, subject to
certain exceptions, act as Paying Agent, Registrar or co-Registrar.

4.    Indenture.

            The Issuers issued the Securities under an Indenture, dated as of
June 20, 2003 (the "Indenture"), among the Issuers and the Trustee. The terms of
the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act, as in effect on the date of
the Indenture. The Securities are subject to all such terms, and Holders of
Securities are referred to the Indenture and said Act for a statement of them.
The Securities are general obligations of the Issuers limited in aggregate
principal amount to $500,000,000. The Indenture pursuant to which this Security
is issued provides an unlimited amount of Additional Securities to be issued
thereunder.

5.    Redemption.

            The Securities will be subject to redemption at any time on or after
June 15, 2008, at the option of the Issuers, in whole or in part, on not less
then 30 nor more than 60 days' prior notice, in amounts of $1,000 or an integral
multiple thereof, at the following redemption prices (expressed as percentages
of the principal amount), if redeemed during the 12 month period beginning June
15 of the years indicated below:

            2011 and thereafter...................        100%
</TABLE>

in each case, together with accrued and unpaid interest, if any, and Additional
Interest to the Redemption Date (subject to the rights of holders of record on
relevant record dates to receive interest due on an interest payment date).

            In addition, at any time prior to June 15, 2006, the Issuers, at
their option, may use the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings in a single transaction or a series of
related transactions to redeem up to an aggregate of 35% of the aggregate
principal amount of Securities originally issued under the Indenture at a
redemption price equal to 110.125% of the aggregate principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the redemption date
(subject to the rights of holders of record on relevant record dates to receive
interest due on an interest payment date); provided that at least 65% of the
initial aggregate principal amount of Securities remains outstanding immediately
after the occurrence of such redemption; provided, further, that any such
redemption with respect to a Strategic Equity Offering may not occur in
connection with or after the occurrence of a Change of Control; provided,
further, that any such net proceeds received by Centennial are first contributed
to the Company as a capital contribution prior to any such redemption. In order
to

                                     A-1-7
<PAGE>
effect the foregoing redemption, the Company must mail a notice of redemption no
later than 30 days after the closing of the related Public Equity Offering or
Strategic Equity Offering and must consummate such redemption within 60 days of
the closing of the Public Equity Offering or Strategic Equity Offering.

            In addition, the Securities may be redeemed upon a Change of Control
at any time prior to June 15, 2008, at the option of the Issuers, in whole and
not in part, within 60 days of such Change of Control, at a redemption price
equal to (i) 100% of the principal amount of the Securities, plus (ii) accrued
interest to the redemption date (subject to the rights of holders of record on
relevant record dates to receive interest due on an interest payment date) plus
(iii) the Applicable Premium, if any. In no event will the redemption price of
the Securities be less than 105.063% (the Redemption Price for the Securities on
June 15, 2008) of the principal amount of the Securities, plus accrued interest
to the applicable Redemption Date.

            In the case of a partial redemption, the Trustee shall select the
Securities or portions thereof for redemption in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed, or if the Securities are not so listed, on a pro rata
basis, by lot or by any other manner as it deems appropriate and fair; provided,
that any such redemption pursuant to the provisions relating to a Public Equity
Offering or a Strategic Equity Offering shall be made on a pro rata basis or on
as nearly a pro rata basis as practicable (subject to the procedures of DTC or
any other depositary). The Securities may be redeemed in part in multiples of
$1,000 only.

            Any such redemption will comply with Article III of the Indenture.

6.    Notice of Redemption.

            Except as provided in the next paragraph, notice of redemption will
be sent by first class mail, at least 30 days and not more than 60 days prior to
the Redemption Date, to the Holder of each Security to be redeemed at such
Holder's last address as then shown upon the registry books of the Registrar.

            Any notice which relates to a Security to be redeemed in part only
must state the portion of the principal amount to be redeemed and must state
that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities in a principal amount equal to the
unredeemed portion thereof will be issued. On and after the date fixed for
redemption, interest will cease to accrue on the portions of the Securities
called for redemption.

7.    Denominations; Transfer; Exchange.

            The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder may register
the transfer of, or exchange Securities in accordance with, the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate

Affiliate thereof shall have any personal liability in respect of the
obligations of the Issuers under the Securities or the Indenture by reason of

in each case, together with accrued and unpaid interest, if any, and Additional
Interest to the Redemption Date (subject to the rights of holders of record on
relevant record dates to receive interest due on an interest payment date).

            In addition, at any time prior to June 15, 2006, the Issuers, at
their option, may use the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings in a single transaction or a series of
related transactions to redeem up to an aggregate of 35% of the aggregate
principal amount of Securities originally issued under the Indenture at a
redemption price equal to 110.125% of the aggregate principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the redemption date
(subject to the rights of holders of record on relevant record dates to receive
interest due on an interest payment date); provided that at least 65% of the
initial aggregate principal amount of Securities remains outstanding immediately
after the occurrence of such redemption; provided, further, that any such
redemption with respect to a Strategic Equity Offering may not occur in
connection with or after the occurrence of a Change of Control; provided,
further, that any such net proceeds received by Centennial are first contributed
to the Company as a capital contribution prior to any such redemption. In order
to

                                     A-2-7
<PAGE>
effect the foregoing redemption, the Company must mail a notice of redemption
no later than 30 days after the closing of the related Public Equity Offering or
Strategic Equity Offering and must consummate such redemption within 60 days of
the closing of the Public Equity Offering or Strategic Equity Offering.

            In addition, the Securities may be redeemed upon a Change of Control
at any time prior to June 15, 2008, at the option of the Issuers, in whole and
not in part, within 60 days of such Change of Control, at a redemption price
equal to (i) 100% of the principal amount of the Securities, plus (ii) accrued
interest to the redemption date (subject to the rights of holders of record on
relevant record dates to receive interest due on an interest payment date) plus
(iii) the Applicable Premium, if any. In no event will the redemption price of
the Securities be less than 105.063% (the Redemption Price for the Securities on
June 15, 2008) of the principal amount of the Securities, plus accrued interest
to the applicable Redemption Date.

            In the case of a partial redemption, the Trustee shall select the
Securities or portions thereof for redemption in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed, or if the Securities are not so listed, on a pro rata
basis, by lot or by any other manner as it deems appropriate and fair; provided,
that any such redemption pursuant to the provisions relating to a Public Equity
Offering or a Strategic Equity Offering shall be made on a pro rata basis or on
as nearly a pro rata basis as practicable (subject to the procedures of DTC or
any other depositary). The Securities may be redeemed in part in multiples of
$1,000 only.

            Any such redemption will comply with Article III of the Indenture.

27.   Notice of Redemption.

            Except as provided in the next paragraph, notice of redemption will
be sent by first class mail, at least 30 days and not more than 60 days prior to
the Redemption Date, to the Holder of each Security to be redeemed at such
Holder's last address as then shown upon the registry books of the Registrar.

            Any notice which relates to a Security to be redeemed in part only
must state the portion of the principal amount to be redeemed and must state
that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities in a principal amount equal to the
unredeemed portion thereof will be issued. On and after the date fixed for
redemption, interest will cease to accrue on the portions of the Securities
called for redemption.

28.   Denominations; Transfer; Exchange.

            The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder may register
the transfer of, or exchange Securities in accordance with, the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Securities selected for redemption prior to 15 days after the
notice of redemption.

29.   Persons Deemed Owners.

<PAGE>
                  The registered Holder of a Security may be treated as the
owner of it for all purposes.

30.      Unclaimed Money.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee and the Paying Agent(s) will pay the money
back to the Issuers. After that, all liability of the Trustee and such Paying
Agent(s) with respect to such money shall cease.

31.      Defeasance and Discharge Prior to Redemption or Maturity.

                  Except as set forth in the Indenture, if the Issuers
irrevocably deposit with the Trustee, in trust, for the benefit of the Holders,
U.S. Legal Tender and Government Securities or a combination thereof, in such
amounts as will be sufficient in the opinion of a nationally recognized firm of
independent public accountants selected by the Trustee, to pay the principal of,
premium, if any, and interest on the Securities to redemption or maturity and
comply with the other provisions of the Indenture relating thereto, the Issuers
will be discharged from certain provisions of the Indenture and the Securities
(including the financial covenants, but excluding their obligation to pay the
principal of (and premium, if any) and interest on the Securities). Upon
satisfaction of certain additional conditions set forth in the Indenture, the
Company may elect to have the Issuers' obligations discharged with respect to
outstanding Securities.

                  In addition, the Indenture will be discharged in full as to
all outstanding Securities when (a) either (i) all Securities are delivered to
the Trustee for authentication or (ii) all Securities not so delivered have
become due and payable, will become due and payable within one year or are to be
called for redemption within one year, and in either event the Issuers have
deposited with the Trustee an amount in United States dollars sufficient to pay
and discharge all of the Securities, (b) the Issuers have paid all other sums
payable under the Indenture by them and (c) the Issuers have delivered an
officer's certificate and opinion of counsel related thereto.

32.      Amendment; Supplement; Waiver.

                  Subject to certain exceptions, the Indenture or the Securities
may be amended or supplemented with the written consent of the Holders of at
least a majority in aggregate principal amount of the Securities then
outstanding, and any existing Default or Event of Default or compliance with any
provision may be waived with the consent of the Holders of a majority in
aggregate principal amount of the Securities then outstanding. Without notice to
or consent of any Holder, the parties thereto may amend or supplement the
Indenture or the Securities to, among other things, cure any ambiguity, defect
or inconsistency, or make any other change that does not adversely affect the
rights of any Holder of a Security.

33.      Restrictive Covenants.

                  The Indenture imposes certain limitations on the ability of
the Company and its Restricted Subsidiaries to, among other things, incur
additional Indebtedness and Disqualified Capital Stock, pay dividends or make
certain other restricted payments, enter into certain transactions with
Affiliates, incur Liens, sell assets, merge or consolidate with any other Person
or transfer (by lease, assignment or otherwise) substantially all of the
properties and assets of the

                                     A-2-9
<PAGE>
Company. The limitations are subject to a number of important qualifications and
exceptions. The Issuers must periodically report to the Trustee on compliance
with such limitations.

34.      Repurchase at Option of Holder.

                  (a) If there is a Change of Control, the Issuers shall be
required to offer to purchase on the Change of Control Purchase Date all
outstanding Securities at a purchase price equal to 101% of the principal amount
thereof, together with any accrued and unpaid interest and Additional Interest,
to the Change of Control Purchase Date. Holders of Securities will receive a
Change of Control Offer from the Issuers prior to any related Change of Control
Purchase Date and may elect to have such Securities purchased by properly
tendering such Securities pursuant to the Change of Control Offer.

                  (b) The Indenture imposes certain limitations on the ability
of the Company and its Restricted Subsidiaries to sell assets. In the event the
proceeds from a permitted Asset Sale exceed certain amounts, as specified in the
Indenture, the Company will be required either to reinvest the proceeds of such
Asset Sale as described in the Indenture or to make an offer to purchase each
Holder's Securities at 100% of the principal amount thereof, plus accrued
interest, if any, to the purchase date.

35.      Successors.

                  When a successor assumes all the obligations of its
predecessor under the Securities and the Indenture, the predecessor will be
released from those obligations.

36.      Defaults and Remedies.

                  If an Event of Default occurs and is continuing (other than as
Event of Default relating to certain events of bankruptcy, insolvency or
reorganization), then in every such case, unless the principal of all of the
Securities shall have already become due and payable, either the Trustee or the
Holders of 25% in aggregate principal amount of Securities then outstanding may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture. The Holders of Securities may not
enforce the Indenture or the Securities except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Securities. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the Securities then outstanding may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of Securities notice of any continuing Default or Event of
Default (except a Default in payment of principal or interest), if it determines
that withholding notice is in their interest.

37.      Trustee Dealings with Issuers.

                  The Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, perform investment
advisory or other management services and perform services for the Issuers or
their Affiliates, and may otherwise deal with the Issuers or their Affiliates as
if it were not the Trustee.

                                     A-2-10

38.      No Recourse Against Others.

                  No direct or indirect stockholder (or partner, limited
liability company member or employee of a stockholder), employee, officer or
director, as such, past, present or future, of the Issuers or any successor
entity or any Affiliate thereof shall have any personal liability in respect of
the obligations of the Issuers under the Securities or the Indenture by reason
of his or its status as such stockholder (or partner, limited liability company
member or employee of a stockholder), employee, officer or director. Each Holder
of a Security by accepting a Security waives and releases all such liability.
The waiver and release are part of the consideration for the issuance of the
Securities.

39.      Authentication.

                  This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on the other side
of this Security.

40.      Abbreviations and Defined Terms.

                  Customary abbreviations may be used in the name of a Holder of
a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

41.      CUSIP Numbers.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Issuers will cause CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the
Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other
identification numbers printed hereon.

42.      Additional Rights of Holders.

                  In addition to the rights provided to Holders of Securities
under the Indenture, Holders of Securities shall have all the rights set forth
in a Registration Rights Agreement dated as of June 20, 2003, between the
Issuers, Centennial Puerto Rico Operations Corp., and Credit Suisse First Boston
LLC, as representative of several Initial Purchasers named therein. In the case
of Additional Securities, Holders of Securities shall have the rights set forth

Puerto Rico Operations Corp., if any (collectively, the "Registration Rights
Agreement").

          (j) Deloitte & Touche LLP, the certified public accountants who have
     certified the consolidated financial statements, together with related
     schedules and notes, included in the Preliminary Circular and the Final
     Circular are independent public accountants with respect to the Issuers
     within the meaning of Regulation S-X of the Securities Act.

          (k) The consolidated financial statements, together with related
     schedules and notes, included in the Preliminary Circular and the Final
     Circular (and any amendment or supplement thereto), present fairly the
     consolidated financial condition, results of operations, cash flows and
     stockholders' equity of the Company and its subsidiaries on the basis
     stated in the Final Circular at the respective dates or for the respective
     periods to which they apply; such statements and related schedules and
     notes have been prepared in accordance with generally accepted accounting
     principles consistently applied throughout the periods involved, except as
     disclosed therein; and the other financial information and data set forth
     in the Preliminary Circular and the Final Circular (and any amendment or
     supplement thereto) is presented fairly and is prepared on a basis
     consistent with the audited financial statements included in the
     Preliminary Circular and the Final Circular.

          (l) The Company has established and maintains disclosure controls and
     procedures (as such term is defined in Rule 13a-14 and 15d-14 under the
     Exchange Act); such disclosure controls and procedures are designed to
     ensure that material information relating to the Company and its
     subsidiaries is made known to the Company's Chief Executive Officer and its
     Chief Financial Officer by others within those entities, and such
     disclosure controls and procedures are effective to perform the functions
     for which they were established; since the date of the filing of the
     Company's Quarterly Report on Form 10-Q for the most recent quarter ended
     for which filings shall have been made, the Company's auditors and the
     Audit Committee of the board of directors of the Company have been advised
     of: (i) any significant deficiencies in the design or operation of internal
     controls which could adversely affect the Company's ability to record,
     process, summarize, and report financial data and (ii) any fraud, whether
     or not material, that

                                       4

<PAGE>

     involves management or other employees who have a role in the Company's
     internal controls; any material weaknesses in internal controls have been
     identified for the Company's auditors; and since the date of the most
     recent evaluation of such disclosure controls and procedures, there have
     been no significant changes in internal controls or in other factors that
     could significantly affect internal controls, including any corrective
     actions with regard to significant deficiencies and material weaknesses.

          (m) There has not occurred any material adverse change, or any
     development involving a prospective material adverse change, in the
     condition, financial or otherwise, or in the earnings, business, properties
     or operations of the Issuers, the Guarantor and their subsidiaries, taken
     as a whole from that set forth in the Final Circular.

          (n) There are no legal or governmental proceedings (including, without
     limitation, those of the Federal Communications Commission or any state,
     local or commonwealth communications agency or commission) pending or to
     our knowledge threatened to which the Company, Centennial Cellular, the
     Guarantor or any of their subsidiaries is a party or to which any of the
     properties of the Company, Centennial Cellular, the Guarantor or any of
     their subsidiaries is subject other than proceedings accurately described
     in all material respects in each Circular and other than proceedings that
     would not reasonably be expected to have a material adverse effect on the
     Issuers, the Guarantor and their subsidiaries, taken as a whole, or on the
     power or ability of the Issuers and the Guarantor to perform their
     respective obligations under this Agreement, the Indenture, the
     Registration Rights Agreement, the Securities, the Guarantee or to
     consummate the transactions contemplated by each such agreement, or to
     apply the net proceeds of the issuance of the Securities as described in
     the Final Circular under the caption "Use of Proceeds".

     Significant Subsidiaries (i) is in compliance with any and all applicable

     LAWS"), (ii) have received all permits, licenses or other approvals
     required of them under applicable Environmental Laws to conduct their
     respective businesses and (iii) are in compliance with all terms and
     conditions of any such permit, license or approval, except where such
     noncompliance with Environmental Laws, failure to receive required permits,
     licenses or other approvals or failure to comply with the terms and
     conditions of such permits, licenses or approvals would not, singly or in
     the aggregate, reasonably be expected to have a material adverse effect on
     the Issuers, the Guarantor and their subsidiaries, taken as a whole.

          (p) There are no costs or liabilities associated with Environmental
     Laws (including, without limitation, any capital or operating expenditures
     required for clean-up, closure of properties or compliance with
     Environmental Laws or any permit, license or approval, any related
     constraints on operating activities and any potential liabilities to third
     parties) which would, singly or in the aggregate, reasonably be expected to
     have a material adverse effect on the Issuers, the Guarantor and their
     subsidiaries, taken as a whole.

     regional and other governmental authorities and all courts and tribunals,
     to own, lease, license and use its properties and assets and to conduct its

     extent the failure to do so would not reasonably be expected to have a
     material adverse effect on the Company, Centennial Cellular, the Guarantor
     and their Significant Subsidiaries taken as a whole; and none of the
     Company, Centennial Cellular, the Guarantor or any of their Significant
     Subsidiaries has received any notice of proceedings relating to revocation
     or modification of any such certificates, orders, permits, licenses,
     authorizations, consents or approvals, nor is the Company, Centennial
     Cellular, the Guarantor or any of their subsidiaries in violation of, or in
     default under, any federal, state, local, foreign supranational, national
     or regional law, regulation, rule, decree, order or judgment applicable to
     the Company, Centennial Cellular, the Guarantor or any of their
     subsidiaries the effect of which, singly or in the aggregate, would
     reasonably be expected to have a material adverse effect on the Company,
     Centennial Cellular, the Guarantor and their Significant subsidiaries,
     taken as a whole, except as described in the Final Circular.

          (s) None of the Company, Centennial Cellular, the Guarantor or any
     affiliate (as defined in Rule 501(b) of Regulation D under the Securities

     offers to buy or otherwise negotiated in respect of, any security (as
     defined in the Securities Act) which is or will be integrated with the sale
     of the Securities and the Guarantee in a manner that would require the
     registration under the Securities Act of the Securities and the Guarantee
     or (ii) offered, solicited offers to buy or sell the Securities and the
     Guarantee by any form of general solicitation or general advertising in
     connection with the offering of the Securities (as those terms are used in
     Regulation D under the Securities Act) or in any manner involving a public
     offering within the meaning of Section 4(2) of the Securities Act.

          (t) None of the Company, Centennial Cellular, the Guarantor, their
     Affiliates or any person acting on any of their behalf (other than the

          (x) The Issuers, the Guarantor and each of their Significant
     Subsidiaries are insured by insurers of recognized financial responsibility
     against such losses and risks and in such amounts as the Issuers and the
     Guarantor reasonably believe are prudent and customary in the businesses in
     which they are engaged; none of the Company, Centennial Cellular, the
     Guarantor or any such subsidiary has been refused any insurance coverage
     sought or applied for, except for any such refusal that would not
     reasonably be expected to have a material adverse effect on the Issuers,
     the Guarantor and their subsidiaries, taken as a whole; and none of the
     Company, Centennial Cellular, the Guarantor or any such subsidiary has any
     reason to believe that it will not be able to renew its existing insurance
     coverage as and when such coverage expires or to obtain similar coverage
     from similar insurers as may be necessary to continue its business at a
     cost that would not reasonably be expected to have a material adverse
     effect on the Issuers, the Guarantor and their subsidiaries, taken as a
     whole, except as described in the Final Circular.

          (y) The Issuers, the Guarantor and each of their subsidiaries keep
     accurate books and records reflecting their respective assets and maintain
     a system of internal accounting controls sufficient to provide reasonable
     assurance that (i) transactions are executed in accordance with

     recorded as necessary to permit preparation of consolidated financial
     statements in conformity with generally accepted accounting principles and
     to maintain asset accountability; (iii) access to assets is permitted only
     in accordance with management's general or specific authorization; and (iv)
     the recorded accountability for assets is compared with the existing assets
     at reasonable intervals and appropriate action is taken with respect to any

     Cellular, the Guarantor or their Significant Subsidiaries exists or, to the
     knowledge of the Issuers, is imminent; none of the Company, Centennial

     existing or imminent labor disturbance by the employees of any of the
     Company's, Centennial Cellular's, the Guarantor's or any of their
     subsidiaries' principal suppliers, manufacturers, customers or contractors
     which, in either case, would reasonably be expected to result in a material

     liens, security interests, claims, restrictions or encumbrances of any kind
     (other than Permitted Liens, as defined in the Indenture) except such as
     would not, singly or in the aggregate, reasonably be expected to materially
     affect the value of such property and would not interfere with the use made
     and proposed to be made of such property by the Company, Centennial
     Cellular, the Guarantor or any of their Significant Subsidiaries, except
     for any such interference that would not reasonably be expected to have a
     material adverse effect on the Issuers, the Guarantor and their
     subsidiaries, taken as a whole; all of the leases and subleases material to
     the business of the Issuers, the Guarantor and their subsidiaries,
     considered as one enterprise, and under which the Company, Centennial
     Cellular, the Guarantor or any of their subsidiaries hold properties, are
     in full force and effect, and none of the Company, Centennial Cellular, the
     Guarantor or any of their subsidiaries, has any notice of any material
     claim of any sort that has been asserted by anyone adverse to the rights of
     the Company, Centennial Cellular, the Guarantor or any of their
     subsidiaries under any of these leases or subleases, or affecting or
     questioning the rights of the Company, Centennial Cellular, the Guarantor
     or any of their subsidiaries to the continued possession of the leased or
     subleased premises under any such lease or sublease, except in each case to
     the extent such would not reasonably be expected to have a material adverse
     effect on the Issuers, the Guarantor and their subsidiaries, taken as a
     whole.

          (bb) All material United States federal income tax returns of the
     Issuers, the Guarantor and their subsidiaries required by law to be filed
     have been filed and all taxes shown by such returns or otherwise assessed,
     which are due and payable, have been paid, except assessments against which
     appeals have been or will be promptly taken and as to which adequate
     reserves have been provided. The Issuers, the Guarantor and their
     subsidiaries have filed all other tax returns that are required to have
     been filed by them pursuant to applicable foreign, federal, state, local or
     other law except insofar as the failure to file such returns would not
     reasonably be expected to result in a material adverse effect on the
     Issuers, the Guarantor and their subsidiaries, taken as a whole, and have
     paid all taxes due pursuant to such returns or pursuant to any assessment
     received by the Issuers, the Guarantor and their subsidiaries, except for
     such taxes, if any, as are being contested in good faith and by appropriate
     proceedings and as to which adequate reserves have been provided. The
     charges, accruals and reserves on the books of the Issuers, the Guarantor
     and their subsidiaries in respect of all federal, state, local and foreign
     tax liabilities of the Issuers, the Guarantor and each subsidiary for any
     years not finally determined are adequate to meet any assessments or
     reassessments for additional income tax for any years not finally
     determined, except to the extent of any inadequacy that would not
     reasonably be expected to result in a material adverse effect on the
     Issuers, the Guarantor and their subsidiaries, taken as a whole.

          (cc) Except as disclosed in the Final Circular, there are no
     contracts, agreements or understandings between the Issuers and/or the
     Guarantor with any person that would give rise to a claim against the
     Issuer, the Guarantor or the Initial Purchasers for a brokerage commission,
     finder's fee or other like payment in connection with this offering.

     similar rights to require the Issuers or the Guarantor to include any
     securities in any registration statement filed pursuant to the Registration

     statement.

          Each certificate signed by any officer of an Issuer or the Guarantor
     and delivered to the Initial Purchasers or their counsel shall be deemed to
     be a representation and warranty by such Issuer or the Guarantor, as the

         certain subsidiaries of the Company, as guarantors; and J.P. Morgan
         Chase Bank and certain other parties thereto, as lenders, shall have
         been amended pursuant to the Fourth Amendment to the Credit Agreement
         substantially in the form as attached hereto as Exhibit E (the
         "AMENDMENT").

                  (k) The Initial Purchasers shall have received such other

         counsel.

                  6.  Covenants of the Company and the Guarantor. In further
consideration of the agreements of the Initial Purchasers contained in this
Agreement, the Issuers and the Guarantor covenant with each Initial Purchaser as
follows:

                  (a) To furnish to you in New York City, without charge, prior
         to 10:00 a.m. New York City time on the business day next succeeding
         the date of this Agreement and during the period mentioned in Section
         6(c), as many copies of the Final Circular, any documents incorporated
         by reference therein and any supplements and amendments thereto as you
         may reasonably request.

                  (b) Before amending or supplementing either Circular, to
         furnish to you a copy of each such proposed amendment or supplement and
         not to use any such proposed amendment or supplement without your
         consent which shall not be unreasonably withheld or delayed.

                  (c) If, during such period after the date hereof and prior to
         the date on which all of the Securities shall have been sold by the
         Initial Purchasers, any event shall occur or condition exist as a
         result of which it is necessary to amend or supplement the Final
         Circular in order to make the statements therein, in the light of the
         circumstances when the Final Circular is delivered to a purchaser, not
         misleading, or if, in the reasonable opinion of counsel for the Initial
         Purchasers, it is necessary to amend or supplement the Final Circular
         to comply with applicable law, forthwith to prepare and furnish, at
         their own expense, to the Initial Purchasers, either amendments or
         supplements to the Final Circular so that the statements in the Final
         Circular as so amended or supplemented will not, in the light of the
         circumstances when the Final Circular is delivered to a purchaser, be
         misleading or so that the Final Circular, as amended or supplemented,
         will comply with applicable law.

         connection with the road show presentations with the prior approval of

         as provided in this Section, Section 8, and the last paragraph of
         Section 10, the Initial Purchasers will pay all of their costs and
         expenses, including fees and disbursements of their counsel, transfer
         taxes payable on resale of any of the Securities by them and any
         advertising expenses connected with any offers they may make.

                  (f) None of the Company, Centennial Cellular, the Guarantor or

         buy or otherwise negotiate in respect of any security (as defined in
         the Securities Act) which could be integrated with the sale of the
         Securities and the Guarantee in a manner which would require the
         registration under the Securities Act of the Securities or the
         Guarantee.

<PAGE>

                  (g) Not to solicit any offer to buy or offer or sell the
         Securities or the Guarantee by means of any form of general
         solicitation or general advertising (as those terms are used in
         Regulation D under the Securities Act) or in any manner involving a
         public offering within the meaning of Section 4(2) of the Securities
         Act.

                  (h) While any of the Securities and the Guarantee remain
         "restricted securities" within the meaning of the Securities Act, to
         make available, upon request, to any seller of the Securities the
         information specified in Rule 144A(d)(4) under the Securities Act,
         unless the Company or Centennial Cellular is then subject to Section 13
         or 15(d) of the Exchange Act.

                  (i) To use their reasonable best efforts to permit the
         Securities to be designated PORTAL securities in accordance with the
         rules and regulations adopted by the NASD.

                  (j) None of the Company, Centennial Cellular, their Affiliates
         or any person acting on its or their behalf (other than the Initial
         Purchasers) will engage in any directed selling efforts (as that term
         is defined in Regulation S) with respect to the Securities or the
         Guarantee, and the Issuers, their Affiliates and each person acting on
         its or their behalf (other than the Initial Purchasers) will comply
         with the offering restrictions requirement of Regulation S.

                  (k) During the period of two years after the Closing Date, the
         Issuers and the Guarantor will not resell any of the Securities which
         constitute "restricted securities" under Rule 144 that have been
         reacquired by any of them.

                  (l) The Issuers will cooperate with the Initial Purchasers and
         use their reasonable best efforts to permit the Securities and the
         Guarantee to be eligible for clearance and settlement through The
         Depository Trust Company.

                  (m) The Issuers will apply the net proceeds received by it
         from the sale of Securities and the Guarantee in the manner specified
         in the Final Circular under the caption "Use of Proceeds".

                  (n) The Issuers and the Guarantor will use their reasonable
         best efforts to enter into the Amendment on or prior to the Closing
         Date.

                  7.  Offering of Securities; Restrictions on Transfer. (a) Each
Initial Purchaser, severally and not jointly, represents and warrants that such
Initial Purchaser is a qualified institutional buyer as defined in Rule 144A
under the Securities Act (a "QIB"). Each Initial Purchaser, severally and not
jointly, agrees with the Issuers and the Guarantor that (i) it has not and will
not solicit offers for, or offer or sell, such Securities or the Guarantee by
any form of general solicitation or general advertising (as those terms are used
in Regulation D under the Securities Act) or in any manner involving a public
offering within the meaning of Section 4(2) of the Securities Act and (ii) it
has not and will not solicit offers for such Securities only from, and will
offer such Securities only to, persons that it reasonably believes to be (A) in
the case of offers inside the United States, QIBs and (B) in the case of offers
outside the United States, to persons other than U.S. persons ("FOREIGN
PURCHASERS," which term shall include

                                       13

<PAGE>

dealers or other professional fiduciaries in the United States acting on a
discretionary basis for foreign beneficial owners (other than an estate or
trust)) in reliance upon Regulation S under the Securities Act that, in each
case, in purchasing such Securities are deemed to have represented and agreed as
provided in the Final Circular under the caption "Transfer Restrictions".

                  (b) Each Initial Purchaser, severally and not jointly,
         represents, warrants, and agrees with respect to offers and sales
         outside the United States that:

                  (i) such Initial Purchaser understands that no action has been
         or will be taken in any jurisdiction by the Company, Centennial
         Cellular or the Guarantor that would permit a public offering of the
         Securities and the Guarantee, or possession or distribution of either
         Circular or any other offering or publicity material relating to the
         Securities and the Guarantee, in any country or jurisdiction where
         action for that purpose is required;

                  (ii) such Initial Purchaser will comply with all applicable
         laws and regulations in each jurisdiction in which it acquires, offers,
         sells or delivers Securities and the Guarantee or has in its possession
         or distributes either Circular or any such other material, in all cases
         at its own expense;

                  (iii) the Securities and the Guarantee have not been
         registered under the Securities Act and may not be offered or sold
         within the United States or to, or for the account or benefit of, U.S.
         persons except in accordance with Rule 144A or Regulation S under the
         Securities Act or pursuant to another exemption from the registration
         requirements of the Securities Act;

                  (iv) such Initial Purchaser has offered the Securities and the
         Guarantee and will offer and sell the Securities (A) as part of their
         distribution at any time and (B) otherwise until 40 days after the
         later of the commencement of the offering and the Closing Date, only in
         accordance with Rule 903 of Regulation S or as otherwise permitted in
         Section 7(a); accordingly, neither such Initial Purchaser, its
         Affiliates nor any persons acting on its or their behalf have engaged
         or will engage in any directed selling efforts (within the meaning of
         Regulation S) with respect to the Securities and the Guarantee, and any
         such Initial Purchaser, its Affiliates and any such persons have
         complied and will comply with the offering restrictions requirement of
         Regulation S;

                  (v) such Initial Purchaser (A) has not offered or sold and,
         prior to the date six months after the Closing Date, will not offer or
         sell any Securities or the Guarantee to persons in the United Kingdom
         except to persons whose ordinary activities involve them in acquiring,
         holding, managing or disposing of investments (as principal or agent)
         for the purposes of their businesses or otherwise in circumstances
         which have not resulted and will not result in an offer to the public
         in the United Kingdom within the meaning of the Public Offers of
         Securities Regulations 1995; (B) has complied and will comply with all
         applicable provisions of the Financial Services and Markets Act 2000
         (the "FSMA") with respect of anything done by it in relation to the
         Securities in, from or otherwise involving the United Kingdom, and (C)
         will only communicate or cause to be communicated any invitation or
         inducement to engage in investment activity (within the meaning of
         section 21 of the FSMA) received by it in connection with the issue or
         sale of

                                       14

<PAGE>

         the Securities in circumstances in which section 21(1) of the FSMA does
         not apply to the Company;

                  (vi) such Initial Purchaser understands that the Securities
         and the Guarantee have not been and will not be registered under the
         Securities and Exchange Law of Japan, and represents that it has not
         offered or sold, and agrees not to offer or sell, directly or
         indirectly, any Securities or the Guarantee in Japan or for the account
         of any resident thereof except pursuant to any exemption from the
         registration requirements of the Securities and Exchange Law of Japan
         and otherwise in compliance with applicable provisions of Japanese law;
         and

                  (vii) such Initial Purchaser agrees that, at or prior to
         confirmation of sales of the Securities, it will have sent to each
         distributor, dealer or person receiving a selling concession, fee or
         other remuneration that purchases Securities from it during the
         restricted period a confirmation or notice to substantially the
         following effect:

                  "The Securities covered hereby have not been registered under
         the U.S. Securities Act of 1933 (the "Securities Act") and may not be
         offered and sold within the United States or to, or for the account or
         benefit of, U.S. persons (i) as part of their distribution at any time
         or (ii) otherwise until 40 days after the later of the commencement of
         the offering and the closing date, except in either case in accordance
         with Regulation S (or Rule 144A if available) under the Securities Act.
         Terms used above have the meaning given to them by Regulation S."

                  Terms used in this Section 7(b) have the meanings given to
them by Regulation S.

                  8.  Indemnity and Contribution. (a) The Company, Centennial
Cellular and the Guarantor agree, jointly and severally, to indemnify and hold
harmless each Initial Purchaser and each person, if any, who controls any
Initial Purchaser within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser
within the meaning of Rule 405 under the Securities Act from and against any and
all losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in either Circular (as
amended or supplemented if the Issuers and the Guarantor shall have furnished
any amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in the light of the circumstances under which they were made not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to any Initial Purchaser furnished to
the Issuers in writing by such Initial Purchaser through you expressly for use
therein; provided however, that the foregoing indemnity agreement with respect
to any Preliminary Circular shall not inure to the benefit of any Initial
Purchaser from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities, or any person controlling such Initial
Purchaser, if it is established that a copy of the Final Circular (as then
amended or supplemented if the Issuers and the Guarantor shall have furnished
any amendments or supplements thereto) was not sent or given by or on behalf of
such Initial Purchaser to such person, at or prior to the written

                                       15

<PAGE>

confirmation of the sale of the Securities to such person, and if the Final
Circular (as so amended or supplemented) would have cured the defect giving rise
to such losses, claims, damages or liabilities, unless such failure is the
result of noncompliance by the Issuers and the Guarantor with Section 6(a)
hereof.

                  (b) Each Initial Purchaser agrees, severally and not jointly,
to indemnify and hold harmless the Issuers, the Guarantor, their directors,
their officers and each person, if any, who controls the Company or Centennial
Cellular within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Issuers and the Guarantor to such Initial Purchaser, but only with
reference to information relating to such Initial Purchaser furnished to the
Issuers in writing by such Initial Purchaser through you expressly for use in
either Circular or any amendments or supplements thereto, where such information
is actually included in either Circular and or any amendment or supplement
thereto. Additionally, each Initial Purchaser acknowledges that the indemnity
contained in (a) above shall not operate to indemnify the Initial Purchasers
regarding the matters described in the prior sentence.

                  (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the reasonable fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
indemnifying party shall not, in respect of the legal expenses of any
indemnified party in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees and expenses of more
than one separate firm of legal counsel (in addition to any local counsel) for
all such indemnified parties and that all such fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing by
Credit Suisse First Boston LLC, in the case of parties indemnified pursuant to
Section 8(a), and by the Issuers and the Guarantor, in the case of parties
indemnified pursuant to Section 8(b). The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent, but
if settled with such consent or if there be a final judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and

                                       16

<PAGE>

(ii) such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

                  (d) To the extent the indemnification provided for in Section
8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect
of any losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Issuers and the Guarantor on the one hand and the
Initial Purchasers on the other hand from the offering of the Securities or (ii)
if the allocation provided by clause 8(d)(i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 8(d)(i) above but also the relative
fault of the Issuers and the Guarantor on the one hand and of the Initial
Purchasers on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Issuers
and the Guarantor on the one hand and the Initial Purchasers on the other hand
in connection with the offering of the Securities shall be deemed to be in the
same respective proportions as the net proceeds from the offering of the
Securities (before deducting expenses) received by the Issuers and the Guarantor
and the total discounts and commissions received by the Initial Purchasers in
respect thereof, bear to the aggregate offering price of the Securities. The
relative fault of the Issuers and the Guarantor on the one hand and of the
Initial Purchasers on the other hand shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Issuers and the Guarantor or by the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Initial
Purchasers' respective obligations to contribute pursuant to this Section 8 are
several in proportion to the respective principal amount of Securities they have
purchased hereunder, and not joint.

                  (e) The Issuers, the Guarantor and the Initial Purchasers
agree that it would not be just or equitable if contribution pursuant to this
Section 8 were determined by pro rata allocation (even if the Initial Purchasers
were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred
to in Section 8(d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages and liabilities referred to in Section
8(d) shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities resold by it in the initial placement of such
Securities were offered to investors exceeds the amount of any damages that such
Initial Purchaser has otherwise been required to pay by reason

                                       17

<PAGE>

of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The remedies provided
for in this Section 8 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any indemnified party at law or in
equity.

                  (f) The indemnity and contribution provisions contained in
this Section 8 and the representations, warranties and other statements of the
Issuers and the Guarantor contained in this Agreement shall remain operative and
in full force and effect regardless of (i) any termination of this Agreement,
(ii) any investigation made by or on behalf of any Initial Purchaser or any
person controlling any Initial Purchaser or any affiliate of any Initial
Purchaser or by or on behalf of the Company, Centennial Cellular or the
Guarantor, their officers or directors or any person controlling the Company,
Centennial Cellular or the Guarantor and (iii) acceptance of and payment for any
of the Securities.

                  9.  Termination. This Agreement shall be subject to
termination by notice given by you to the Issuers and the Guarantor, if
subsequent to the execution and delivery of this Agreement, there shall have
occurred (i) any change, or any development or event involving a prospective
change, in the condition (financial or other), business, properties or results
of operations of the Company and its subsidiaries taken as one enterprise which,
in the judgment of Credit Suisse First Boston LLC is material and adverse and
makes it impractical or inadvisable to proceed with the completion of the
offering or the sale of and payment for the Securities and the Guarantee; (ii)
any downgrading in the rating of any debt securities of the Issuers by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Securities Act), or any public announcement that any
such organization has under surveillance or review its rating of any debt
securities of the Issuers (other than an announcement with positive implications
of a possible upgrading, and no implication of a possible downgrading, of such
rating) or any announcement that the Company or Centennial Cellular has been
placed on negative outlook; (iii) any change in U.S. or international financial,
political or economic conditions or currency exchange rates or exchange controls
as would, in the judgment of Credit Suisse First Boston LLC, be likely to
prejudice materially the success of the proposed issue, sale or distribution of
the Securities and the Guarantee, whether in the primary market or in respect of
dealings in the secondary market; (iv) any material suspension or material
limitation of trading in securities generally on the New York Stock Exchange or
any setting of minimum prices for trading on such exchange, or any suspension of
trading of any securities of the Issuers on any exchange or in the
over-the-counter market; (v) any banking moratorium declared by U.S. Federal or
New York authorities; (vi) any major disruption of settlements of securities or
clearance services in the United States or (vii) any attack on, outbreak or
escalation of hostilities or act of terrorism involving the United States, any
declaration of war by Congress or any other national or international calamity
or emergency if, in the judgment of Credit Suisse First Boston LLC, the effect
of any such attack, outbreak, escalation, act, declaration, calamity or
emergency makes it impractical or inadvisable to proceed with completion of the
offering or sale of and payment for the Securities and the Guarantee.

                  10. Effectiveness; Defaulting Initial Purchasers.  This
Agreement shall become effective upon the execution and delivery hereof by the
parties hereto.

                  If, on the Closing Date, any one or more of the Initial
Purchasers shall fail or refuse to purchase Securities that it or they have
agreed to purchase hereunder on such date, and the aggregate principal amount of
Securities which such defaulting Initial Purchaser or Initial Purchasers agreed
but failed or refused to purchase is not more than one-tenth of the aggregate
principal amount of Securities to be purchased on such date, the other Initial
Purchasers shall be obligated severally in the proportions that the principal
amount of Securities set forth opposite their respective names in Schedule I
bears to the aggregate principal amount of Securities set forth opposite the
names of all such non-defaulting Initial Purchasers, or in such other
proportions as you may specify, to purchase the Securities which such defaulting
Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase
on such date; provided that in no event shall the principal amount of Securities
that any Initial Purchaser has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 10 by an amount in excess of one-ninth of
such principal amount of Securities without the written consent of such Initial
Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers
shall fail or refuse to purchase Securities which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of Securities
with respect to which such default occurs is more than one-tenth of the
aggregate principal amount of Securities to be purchased on such date, and
arrangements satisfactory to you and the Issuers for the purchase of such
Securities are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Initial Purchaser
or of the Issuers and the Guarantor. In any such case either you or the Issuers
shall have the right to postpone the Closing Date, but in no event for longer
than seven days, in order that the required changes, if any, in the Final
Circular or in any other documents or arrangements may be effected. Any action
taken under this paragraph shall not relieve any defaulting Initial Purchaser
from liability in respect of any default of such Initial Purchaser under this
Agreement.

                  If this Agreement shall be terminated by the Initial
Purchasers, or any of them, because of any failure or refusal on the part of the
Company, Centennial Cellular or the Guarantor to comply with the terms or to
fulfill any of the conditions of this Agreement, or if for any reason the
Company, Centennial Cellular or the Guarantor shall be unable to perform its
obligations under this Agreement, the Issuers will reimburse the Initial
Purchasers or such Initial Purchasers as have so terminated this Agreement with
respect to themselves, severally, for all reasonable fees and disbursements of
their counsel in connection with this Agreement or the offering contemplated
hereunder, provided that the Issuers shall have no obligation to reimburse any
Initial Purchaser that has breached its obligations hereunder for any such
out-of-pocket expenses.
