things necessary, proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement, including taking all acts
necessary to cause the conditions to Closing to be satisfied as promptly as practicable. No Party
will take any action inconsistent with its obligations under this Agreement or that could hinder or
delay the consummation of the transactions contemplated by this Agreement, except that nothing in
this Section 5.5 shall limit the rights of either Party to terminate this Agreement if
permitted under Section 7.

SECTION 7. TERMINATION

     7.1 Termination. This Agreement may be terminated and the transactions contemplated
hereby may be abandoned at any time prior to the Closing:

     (a) by mutual consent of Buyer and Seller;

     (b) by Buyer (i) if any of the conditions in Section 6.1 or Section 6.2
shall have become incapable of fulfillment by May 1, 2006 (the “First Outside Date”)
and shall not have been waived in writing by the Buyer, or (ii) at any time after the First
Outside Date;

     (c) by Seller if any of the conditions in Section 6.1, other than Section
6.1(d), or Section 6.3 shall have become incapable of fulfillment by the First
Outside Date and shall not have been waived in writing by Seller or, in the case of the
condition contained in Section 6.1(d), shall not have been fulfilled or otherwise
waived in writing by Seller by September 30, 2006 (the “Second Outside Date”);

     (d) by Seller at any time after the Second Outside Date;

     (e) by Buyer or Seller if any Governmental Authority of competent jurisdiction shall
have issued an order, decree or injunction or taken any other action restraining, enjoining
or otherwise prohibiting the transactions contemplated by this Agreement and such order,
decree or injunction or other action shall have been final and non-appealable;

     provided, however, that (i) the right to terminate this Agreement pursuant to Section
7.1(b) or Section 7.1(c) shall not be available to a Party if such Party, at such time,
is in material breach of any representation, warranty, covenant or agreement set forth in this
Agreement, and (ii) the right to terminate this Agreement pursuant to Section 7.1(d) shall
not be available to a Party if such Party, at such time, is in breach of any representation,
warranty, covenant or

11

 

agreement set forth in this Agreement and such breach is the primary cause
for the failure to close by the Outside Date.

     7.2 Effect of Termination. In the event of termination of this Agreement pursuant to
Section 7.1, written notice thereof shall be given by a Party so terminating to the other
Party and, except as provided in this Section 7.2, this Agreement shall forthwith terminate
and shall become null and void and of no further effect, and the transactions contemplated by this
Agreement shall be abandoned without further action by Buyer or Seller. If this Agreement is
terminated under Section 7.1 of this Agreement:

extent practicable, be withdrawn from the agency or other Person to which made;

     (c) There shall be no liability or obligation under this Agreement on the part of Buyer
or Seller or any of their respective Affiliates, directors, officers, managers, employees,
agents or representatives, except (i) that Seller or Buyer, as the case may be, may have
liability to the other Party if the basis of termination is a willful, material breach by
Buyer or Seller, as the case may be, of one or more of the provisions of this Agreement, and
(ii) the obligations provided in this Section 7.2 and Section 9 shall
survive any such termination.

SECTION 8. INDEMNIFICATION

     8.1 The Seller’s Indemnification Obligations. From and after the Closing, the Seller
and NRG agree, jointly and severally, to indemnify, defend and hold harmless the Buyer, Dynegy and
their respective officers, directors, members, managers, stockholders, Affiliates, employees,
successors and assigns (the collectively, the “Buyer Indemnified Parties”) from and against
and reimburse each of the Buyer Indemnified Parties with respect to any and all damages,
liabilities, penalties, fines, losses, costs and expenses (including, without limitation,
reasonable legal fees and expenses, including such fees and expenses in any arbitration, mediation,
litigation and on any appeal) (collectively referred to as “Losses”) suffered or incurred
by and all claims, actions, suits, or demands made against any Buyer Indemnified Party arising out
of or relating to:

     (a) any breach of any representation or warranty of the Seller or NRG contained in this
Agreement (including any of the related Disclosure Schedules thereto), any certificate
delivered by or on behalf of the Seller at the Closing or any Ancillary Agreement; and

     (b) any failure to perform any covenant of the Seller or Dynegy contained in this
Agreement or any Ancillary Agreement.

12

 

     8.2 The Buyer’s Indemnification Obligations. From and after the Closing, Buyer and
Dynegy agree, jointly and severally, to indemnify, defend and hold harmless the Seller, NRG and
their respective officers, directors, members, managers, stockholders, Affiliates, employees,
successors and assigns (collectively, the “Seller Indemnified Parties”) from and against
and reimburse each of the Seller Indemnified Parties with respect to any and all Losses suffered or
incurred by, and all claims, actions, suits or demands made against a Seller Indemnified Party
arising out of or relating to:

     (a) any breach of any representation or warranty of the Buyer contained in this
Agreement (including any of the related Disclosure Schedules thereto), in any certificate
delivered by or on behalf of the Buyer or Dynegy at the Closing and any Ancillary Agreement;
and

     (b) any failure to perform any covenants of the Buyer or Dynegy contained in this
Agreement or any Ancillary Agreement.

     8.3 Environmental Indemnification. Without limiting the generality of the obligations
of Buyer set forth in Section 8.2 above, Buyer and Dynegy agree, jointly and severally, to
release, indemnify, defend and hold harmless the Seller Indemnified Parties from and against, and
agree not to sue or join the Seller Indemnified Parties in any lawsuit or proceeding for, any and
all claims, actions, suits, demands, liabilities (including, without limitation, strict liability
arising under Environmental Laws), obligations, damages, judgments, awards, penalties, settlements,
fines, losses, costs, and expenses (including, without limitation, reasonable legal fees), of any
kind or nature, directly or indirectly resulting from, relating to or arising out of the following
and attributable to or arising from any event, condition, circumstance, activity, practice,
incident, action or plan existing, commencing, or occurring at any time, whether prior to or after
the closing, relating in any way to RRP or Termo Alpha or any of their respective assets or
Business Facilities (including without limitation the ownership, operation or use of any of the
Business Facilities):

     (a) Any actual or threatened violation of, liability under, non-compliance with, or
environmental response obligation arising pursuant to, any Environmental Laws;

     (b) Any liability, including, without limitation, strict liability, associated with the
treatment, storage, disposal, or transportation for treatment, storage, or disposal, of
Materials of Environmental Concern generated at any time by RRP, Termo Alpha or the Facility
or for which RRP or Termo Alpha arranged at any time for treatment, storage or disposal; and

     (c) The presence at any time of any Materials of Environmental Concern exceeding
naturally-occurring concentrations on, in, under or affecting all or any portion of any of
the Business Facilities of RRP or Termo Alpha or the Facility and any release or threatened
release at any time with respect to Materials of Environmental Concern.

     The obligations of the Buyer and Dynegy hereunder are not contingent upon the assertion of a
claim, directive, action or proceeding by a Governmental Authority or third party. Buyer

13

 

and
Dynegy shall be solely liable for all such environmental matters notwithstanding any Seller
Indemnified Party’s potential strict liability or alleged negligence.

     8.4 Tax Liability. Notwithstanding anything contained herein to the contrary, the
Buyer shall be under no duty or obligation to indemnify the Seller for any income tax liability due
to the assignment, sale or transfer of the Membership Interests.

     8.5 Survival Periods. The representations and warranties set forth in Section
3 and Section 4 shall survive the Closing for a period of two years; provided, however,
that the representations and warranties set forth in Section 3.1 (Ownership of Membership
Interests), Section 3.2 (Authority of Seller) and Section 4.2 (Authority of Buyer)
shall survive the Closing indefinitely. All other covenants and agreements of the Parties set
forth in this Agreement shall survive the Closing indefinitely.

     8.6 Limitations on Liability.

     (a) In no event shall Seller or NRG (determined on a combined basis) have any liability
or obligation with respect to claims pursuant to Section 8.1 for any amounts in
excess of the aggregate Purchase Price.

     (b) In no event shall Buyer or Dynegy (determined on a combined basis) have any
liability or obligation with respect to claims pursuant to Section 8.2 or
Section 8.3 for any amounts in excess of the aggregate Purchase Price.

     (c) No indemnifying Party (“Indemnitor”) shall have any obligation to indemnify
a Party for special, punitive, indirect or consequential damages, lost profits or similar
items, except with respect to matters involving actions, claims or other proceedings brought
or asserted by third parties and then only to the extent that an indemnified party
(“Indemnified Party”) is required to pay any such damages, lost profits or similar
items to such third parties. Nothing in this Agreement is intended to require the payment
by the Indemnitor of duplicative, in whole or in part, indemnity payments to an Indemnified
Party.

     (d) The amount of any Losses for which indemnification is provided by an Indemnitor
under Section 8.1 or Section 8.2 shall be net of (1) any amounts recovered
by the Indemnified Party with respect to such Losses pursuant to any indemnification by or
indemnification agreement with any third party in excess of any associated cost to the
Indemnified Party in obtaining such indemnification; (2) any insurance proceeds or other
reimbursement received as an offset against such Losses (and no right of subrogation shall
accrue hereunder to any insurer or third-party indemnitor); and (3) an amount equal to the
net cash tax benefit actually received attributable to such Losses. If the amount to be
netted is determined after payment by the Indemnitor of any amount, the Indemnified Party
shall repay to the Indemnitor, promptly after such determination, any amount that the
Indemnitor would not have had to pay pursuant to this Section 8.6 had such
determination been made at the time of payment.

     (e) All indemnification payments made in accordance with this Section 8 will be
treated as an adjustment to the Purchase Price, except to the extent that the Laws of a

14

 

particular jurisdiction provide otherwise, in which case such payments shall be made in an
amount sufficient to indemnify the relevant Party on an after-Tax basis (determined by
reference to actual out-of-pocket Tax liability incurred by the relevant Party).

     (f) Any claim for indemnification with respect to any of such matters identified in
Section 8.5 above which is not asserted by notice given as herein provided within
such specified period of survival may not be pursued and is hereby irrevocably waived after
such time.

     (g) No Party shall be required to pay or be liable for any Losses with respect to an
individual claim (which individual claim shall include claims arising out of the same or
substantially related circumstances) under Section 8.1 or Section 8.2 unless
and until the Losses for such claim exceed One Hundred Fifty Thousand Dollars ($150,000)
(the “De Minimis Amount”).

     (h) Except claims made pursuant to the Litigation Agreement for which there shall be no
Deductible, no Party shall be required to pay or be liable with respect to any claim for
indemnification under Section 8.1 or Section 8.2 unless and until the
aggregate amount of Losses to Buyer’s Indemnified Persons based upon, attributable to or
resulting from these indemnities of Sellers exceed, in the aggregate, Six Hundred Fifty
Thousand Dollars ($650,000) (the “Deductible”), disregarding any individual claim
(which individual claim shall include claims arising out of the same or substantially
related circumstances) that does not exceed the De Minimis Amount applicable pursuant to
Section 8.6(g) and then only to the extent that such Losses exceed the Deductible.

     8.7 Procedure for Indemnification Claims.

     (a) Third Party Claims.

     (i) Each Party shall, with reasonable promptness after obtaining knowledge
thereof, provide the other Party or parties against whom a claim for indemnification
is to be made under this Section 8 with written notice of all third party
actions, suits, proceedings, claims, demands or assessments that may be subject to
the indemnification provisions of this Section 8, (collectively, “Third
Party Claims”), which notice shall include a statement of the basis of the claim
for indemnification, including a summary of the facts or circumstances that form the
basis for the claim, a good faith estimate of the amount of Losses claimed by the
third party and copies of any pleadings or demands from the third party.
Notwithstanding the foregoing, provided that such notice is in any event given
within the survival periods stated in Section 8.5, the failure to provide
such notice reasonably promptly shall not release the Indemnitor from any of its
obligations under this Section 8, except to the extent that the Indemnitor
is materially prejudiced by such failure, and shall not relieve the Indemnitor from
any other obligation or liability that it may have to the Indemnified Party
otherwise than under this Section 8.

15

 

     (ii) A potential Indemnitor shall have 30 days after its receipt of the claim
notice to notify the potential Indemnified Party in writing whether or not the
potential Indemnitor agrees that the claim is subject to this Section 8 and,
if so, whether the Indemnitor elects to undertake, conduct and control, through
counsel of its choosing (subject to the consent of the Indemnified Party, such
consent not to be withheld unreasonably) and at its sole risk and expense, the
settlement or defense of the Third Party Claim; provided, however, that if legal
counsel to the Indemnified Party determines, in writing provided to Indemnitor, that
there exists or is reasonably likely to exist a conflict of interest which makes it
inappropriate for the same counsel to represent both the Indemnified Party and the
Indemnitor, then the Indemnified Party shall be entitled to retain its own counsel
(such counsel subject to the reasonable approval of the Indemnitor), with the
reasonable costs and expenses of such counsel to be paid by the Indemnitor.

     (iii) If within 30 days after its receipt of the claim notice the Indemnitor
notifies the Indemnified Party that it elects to undertake the settlement or defense
of the Third Party Claim, the Indemnified Party shall cooperate reasonably with the
Indemnitor in connection therewith including, without limitation, by making
available to the Indemnitor all relevant information and the testimony of employees
material to the defense of the Third Party Claim. The Indemnitor shall reimburse the
Indemnified Party for reasonable out-of-pocket costs incurred in connection with
such cooperation. The Indemnified Party shall be entitled to approve any proposed
settlement that would impose any obligation or duty on the Indemnified Party or
include a finding or admission of any violation of applicable law on the part of the
Indemnified Party, which approval shall not be unreasonably withheld. So long as the
Indemnitor is diligently and in good faith contesting the Third Party Claim (1) the
Indemnified Party shall be entitled to participate in all aspects of, but not
conduct or control, the settlement or defense of the Third Party Claim through
counsel and advisors chosen by the Indemnified Party, at its expense, and (2) the
Indemnified Party shall not pay or settle the Third Party Claim. Notwithstanding the
foregoing, the Indemnified Party shall have the right to pay or settle any Third
Party Claim at any time without the consent of the Indemnitor, provided that the
terms and conditions of such settlement involve solely the payment of money damages
and the Indemnified Party waives any right to indemnification therefor by the
Indemnitor.

     (iv) If the potential Indemnitor does not provide the notice described in
Section 8.7(a)(ii) within the 30-day period required thereby or if the
potential Indemnitor fails to either contest or undertake settlement negotiations in
connection with the Third Party Claim, the Indemnified Party shall thereafter have
the right to contest, settle or reach a compromise with respect to the Third Party
Claim at its exclusive discretion, at the risk and expense of the Indemnitor, and
the Indemnitor will thereby waive any claim, defense or argument that the
Indemnified Party’s settlement or defense of such Third Party Claim is in any
respect inadequate or unreasonable. Notwithstanding the foregoing, if the potential
Indemnitor fails to provide the notice described in Section 8.7(a)(ii)
within the 30-day period required thereby, the potential Indemnified Party shall

16

 

provide one fax notice of such Third Party Claim to the chief legal officer of the
potential Indemnitor. If the Potential Indemnitor still does not provide the
required notice within three days after receipt of such fax notice, the potential
Indemnitor shall not be deemed by such failure to have accepted liability for the
Third Party Claim except to the extent that the Indemnified Party is materially
prejudiced by the failure to provide notice within the 30-day period.

     (b) Non Third Party Claims.

     (i) Each Party shall deliver to the other Party or parties against whom a claim
for indemnification is to be made under this Section 8 written notice of any
claims for indemnification under this Section 8, other than Third Party
Claims, which notice shall include a statement of the basis of the claim for
indemnification, including a summary of the facts or circumstances that form the
basis for the claim, and a good faith estimate of the actual or future potential
amount of Losses.

     (ii) A potential Indemnitor shall have 30 days after its receipt of the claim
notice to notify the potential Indemnified Party in writing whether or not the
potential Indemnitor agrees that the claim is subject to this Section 8 (a
“Response Notice”). If the potential Indemnitor does not provide a Response
Notice to the Indemnified Party within the required 30-day period, the Indemnitor
shall be deemed to accept liability for all Losses described in the claim notice.
Notwithstanding the foregoing, if the potential Indemnitor fails to provide a
Response Notice within such 30-day time period the potential Indemnified Party shall
provide one fax notice of such claim to an officer of the potential Indemnitor. If
the potential Indemnitor does provide a Response Notice within three days after
receipt of such fax notice, the potential Indemnitor shall not be deemed by such
failure to have accepted liability for the claim except to the extent that the
Indemnified Party is materially prejudiced by the failure to provide such notice
within the 30-day period.

     (c) Exclusive Remedy. A Party’s right to indemnification provided in this
Section 8 is the sole and exclusive remedy of that Party from and after the Closing
with respect to any Losses arising out of or relating to the negotiation, execution,
delivery, performance or non-performance of this Agreement or the transactions contemplated
hereby; provided, however, that nothing in this Section 8.8 shall restrict or
prohibit any Party from bringing any action (i) for injunctive relief or specific
performance to the extent legally available or (ii) in the event of fraud by a Party. Each
Party waives any provision of applicable Law to the extent it would initiate, limit or
restrict the agreement in this Section 8.8.

SECTION 9. MISCELLANEOUS

     9.1 Costs and Expenses. Unless otherwise expressly provided in this Agreement, each
Party shall pay be responsible for and pay its own costs and expenses associated with the

instrument executed by the Seller and the Buyer. Except as may be otherwise provided in this
Agreement, no waiver of any of the provisions of this Agreement shall be deemed, or shall
constitute, a waiver of any other provision, whether or not similar, nor shall any waiver
constitute a continuing waiver, and no waiver shall be binding on any Party unless evidenced by an
instrument in writing executed by the Party against whom the waiver is sought to be enforced.

may be by facsimile followed thereafter by the originally executed document forwarded promptly
thereafter to the other Party, each of which shall be deemed an original, and all of which together

information, and, unless required to do so by applicable law, applicable rules of stock exchanges,
or generally accepted accounting principles, neither the Seller nor the Buyer shall disclose any
information relative to the terms hereof to any third party without the prior consent of the other,
such consent not to be unreasonably withheld or delayed.

any business or any assets out of the ordinary course of business, whether by
merger, stock purchase or sale or asset purchase or sale, made by such Person
and its Subsidiaries from the beginning of the Reference Period through the

Indebtedness, (a) the transaction giving rise to the need to calculate the
Annual Debt to EBITDA Ratio will be assumed to have occurred (on a pro forma
basis) on the first day of the Reference Period; (b) the Incurrence of any
Indebtedness during the Reference Period or subsequent thereto and on or prior
to the Transaction Date (and the application of the proceeds therefrom to the
extent used to retire Indebtedness or to acquire businesses) will be assumed to
have occurred (on a pro forma basis) on the first day of such Reference Period;
(c) Consolidated Interest Expense attributable to any Indebtedness (whether
existing or being incurred) bearing a floating interest rate shall be computed

for the entire period; and (d) all members of the consolidated group of such
Person on the Transaction Date that were acquired during the Reference Period

entire Reference Period. When the foregoing

                                       2

<PAGE>

definition is used in connection with the Issuer and its Restricted

Subsidiaries. Any such pro forma calculation may include adjustments for the pro
forma effect of (a) any cost savings accounted for on an annualized basis as a
result of an acquisition by the Issuer (or CCOC, as applicable) or a Restricted
Subsidiary which, in the good faith judgment of the Issuer (or CCOC, as
applicable) (as determined by a resolution of the Board of Directors of the
Issuer), will be eliminated or realized within one year after the date of such
transaction (provided that any such cost savings are calculated in accordance
with Regulation S-X under the Securities Act (or any successor regulation)) or
(b) any direct quantifiable savings from the conversion of roaming expense which
the Issuer (or CCOC, as applicable) will obtain within one year of the
transaction in the good faith judgment of the Board of Directors of the Issuer
from the acquisition of a third party which prior to such acquisition had a
contract with the Issuer (or CCOC, as applicable) or any Restricted Subsidiary
for roaming services.

          "Applicable Procedures" means, with respect to any transfer or
transaction involving a Global Security or beneficial interest therein, the

          "Asset Sale Offer" shall have the meaning specified in Section 4.13.

          "Asset Sale Offer Amount" shall have the meaning specified in Section
4.13.

          "Asset Sale Offer Period" shall have the meaning specified in Section
4.13.

          "Asset Sale Offer Price" shall have the meaning specified in Section
4.13.

          "Asset Sale Purchase Date" shall have the meaning specified in Section
4.13.

          "Attributable Amount" means, with respect to any Sale/Leaseback
Transaction involving any Principal Property, as at the time of determination,
the present value (discounted at the interest rate borne by the Securities,
compounded annually) of the total obligations of the lessee for rental payments
(other than amounts required to be paid on account of property taxes,
maintenance, repairs, insurance, assessments, utilities, operating and labor
costs and other items that do not constitute payments for property rights)
during the remaining term of the lease included in such Sale/Leaseback
Transaction (including any period for which such lease has been extended);
provided, however, that the Attributable Amount of each of the following
Sale/Leaseback Transactions involving a Principal Property shall, in each case,
be zero:

               1. a Sale/Leaseback Transaction in which the lease is for a
     period, including renewal rights, not in excess of three years;

               2. a Sale/Leaseback Transaction in which the transfer of the
     Principal Property is made within 270 days of the acquisition or
     construction of, or the completion of a material improvement to, such
     Principal Property;

                                       3

<PAGE>

               3. a Sale/Leaseback Transaction in which the transaction is
     between or among the Issuer and one or more Restricted Subsidiaries or
     between or among Restricted Subsidiaries; or

               4. a Sale/Leaseback Transaction pursuant to which the Issuer,
     within 270 days after the completion of the transfer of the Principal
     Property, applies toward the retirement of its Indebtedness or the
     Indebtedness of a Restricted Subsidiary, or to the purchase of other
     property constituting a Principal Property, the greater of the net proceeds
     from the transfer of the Principal Property and the fair market value of
     the Principal Property; provided, however, that the amount that must be
     applied to the retirement of Indebtedness shall be reduced by:

               (a) the principal amount of any debentures, notes or debt
          securities (including the notes) of the Issuer or a Restricted
          Subsidiary surrendered to the applicable trustee or agent for
          retirement and cancellation within 270 days of the completion of the
          transfer of the Principal Property;

               (b) the principal amount of any Indebtedness not included in
          clause (4)(a) of this definition to the extent such amount of
          Indebtedness is voluntarily retired by the Issuer or a Restricted
          Subsidiary within 270 days of the completion of the transfer of the
          Principal Property; and

               (c) all fees and expenses associated with the Sale/Leaseback
          Transaction.

          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 Issuer 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 Issuer for Definitive Securities if (i) the
Issuer delivers 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 Issuer within 90 days after the date of such
notice from the Depositary; (ii) the Issuer in its 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; 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:

          (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. 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

                                       31

<PAGE>

     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. Upon consummation of an Exchange Offer by the Issuer 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:

               (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

          (iv) Transfer and Exchange of Beneficial Interests in a Restricted
     Global Security for Beneficial Interests in an 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
     Section 2.6(b)(ii) above and:

               (A) such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement

          and in the Private Placement Legend are no longer required in order to
          maintain compliance with the Securities Act.

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

     equal to the principal amount of Definitive Securities so transferred.

          (e) Transfer and Exchange of Definitive Securities for Definitive
Securities. Upon request by a Holder of Definitive Securities and such Holder's
compliance with the provisions of this Section 2.6(e), the Registrar shall

     Securities. Any Restricted Definitive Security may be exchanged by the
     Holder thereof for an Unrestricted Definitive Security or transferred to a
     Person or Persons who take delivery thereof in the form of an Unrestricted

               (C) any such transfer is effected by a Broker-Dealer pursuant to
          the Exchange Offer Registration Statement in accordance with the
          Registration Rights Agreement; or

               (D) the Registrar receives the following:

                         (1) if the Holder of such Restricted Definitive
                    Securities proposes to exchange such Securities for an
                    Unrestricted Definitive Security, a certificate from such

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

          transfer contained herein and in the Private Placement Legend are no
          longer required in order to maintain compliance with the Securities
          Act.

          (iii) Unrestricted Definitive Securities to Unrestricted Definitive
     Securities. A Holder of Unrestricted Definitive Securities may transfer
     such Securities to a Person who takes delivery thereof in the form of an
     Unrestricted Definitive Security. Upon receipt of a request to register
     such a transfer, the Registrar shall register the Unrestricted Definitive
     Securities pursuant to the instructions from the Holder thereof.

Indenture.

          (g) Legends. The following legends shall appear on the face of all
Global Securities and Definitive Securities issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

          SECURITY AGREES THAT IT WILL FURNISH TO THE ISSUER AND THE TRUSTEE
          SUCH CERTIFICATES AND OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE
          TO CONFIRM THAT ANY TRANSFER BY IT OF THIS SECURITY COMPLIES WITH THE
          FOREGOING RESTRICTIONS. THE HOLDER HEREOF, BY PURCHASING THIS
          SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF THE ISSUER THAT IT

          THE MEANING OF (OR AN ACCOUNT SATISFYING THE REQUIREMENTS OF PARAGRAPH
          (k)(2) OF RULE 902 UNDER THE SECURITIES ACT) REGULATION S UNDER THE
          SECURITIES ACT.

Notwithstanding the foregoing, any Global Security or Definitive Security issued
pursuant to subparagraph (b)(iv), (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii),
(e)(iii) or (f) of this Section 2.6 (and all Securities issued in exchange
therefor or substitution thereof) shall not bear the Private Placement Legend.

          (ii) Global Security Legend. Each Global Security shall bear a legend
     in substantially the following form:

          THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
          INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE
          BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO
          ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY
          MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO

                                       41

          SECTION 2.6 OF THE INDENTURE, (II) THIS GLOBAL SECURITY MAY BE
          EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.6(a) OF THE
          INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE
          FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV)
          THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH
          THE PRIOR WRITTEN CONSENT OF THE ISSUER.

          (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
          Issuer shall execute and the Trustee shall authenticate Global
          Securities and Definitive Securities upon the Issuer's 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 Issuer 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 Issuer, 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 Issuer 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 Issuer 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 Issuer 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

          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 Issuer shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's requirements are met. If
required by the Trustee or the Issuer, such Holder must provide an indemnity
bond or other indemnity, sufficient in the judgment of the Issuer and the
Trustee, to protect the Issuer, the Trustee or any Agent from any loss which any
of them may suffer if a Security is replaced. The Issuer may charge such Holder
for its reasonable, out-of-pocket expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Issuer.

          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 Issuer or
an Affiliate of the Issuer 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 Issuer or an Affiliate of the Issuer) 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 Issuer or Affiliates of the Issuer 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.

<PAGE>

          SECTION 2.10. Temporary Securities.

          Until definitive Securities are ready for delivery, the Issuer 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 Issuer reasonably and in good faith considers
appropriate for temporary Securities. Without unreasonable delay, the Issuer
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 Issuer 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 Issuer or an Affiliate of the Issuer), and no one else, shall
cancel and, at the written direction of the Issuer, shall dispose of all
Securities surrendered for transfer, exchange, payment or cancellation. Subject
to Section 2.7, the Issuer 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 Issuer, at its
election in each case, as provided in clause (1) or (2) below:

          (1) The Issuer may elect to make payment of any Defaulted Interest to
     the persons in whose names the Securities (or their respective predecessor
     Securities) are registered at the close of business on a Special Record
     Date for the payment of such Defaulted Interest, which shall be fixed in
     the following manner. The Issuer shall notify the Trustee in writing of the
     amount of Defaulted Interest proposed to be paid on each Security and the
     date of the proposed payment, and at the same time the Issuer 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 Issuer of such
     Special Record Date and, in the name and at the expense of the Issuer,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder 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 Issuer 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 exchange, if, after notice given by the Issuer 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 Issuer 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 Issuer nor the Trustee shall be
liable for any inaccuracy in such numbers.

          SECTION 2.14. Additional Securities

          The Issuer shall be entitled, subject to its compliance with Section
4.10, to issue Additional Securities under this Indenture which shall have
identical terms as the Securities issued on the Issue Date or the Exchange
Securities, other than with respect to the date of issuance and issue price,
first payment of interest and rights under a related Registration Rights
Agreement, if any.

          With respect to any Additional Securities, the Issuer shall set forth
in a resolution of the Board of Directors and an Officers' Certificate, a copy
of each which shall be delivered to the Trustee, the following information:

               (a) the aggregate principal amount at maturity of such Additional
          Securities to be authenticated and delivered pursuant to this
          Indenture;

               (b) the issue price, the issue date and the CUSIP number and
          corresponding ISIN of such Additional Securities; and

               (c) whether such Additional Securities shall bear the Private
          Placement Legend or shall be Exchange Securities.

                                   ARTICLE III
                                   REDEMPTION

          SECTION 3.1. Rights of Redemption.

          (a) In addition to the provisions of Sections 4.13 and 10.1 hereof,
the Securities are subject to redemption at any time on or after January 1,
2008, at the option of the Issuer, 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, but not including, the Redemption Date (subject to the rights of Holders on
relevant Record Dates to receive interest due on an Interest Payment Date).

          (b) In addition, at any time prior to January 1, 2008, the Issuer, at
its option, may use the net cash proceeds of one or more 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 issued under
this Indenture (including Additional Securities) at a Redemption Price equal to
100.0% of the aggregate principal amount thereof, plus a premium equal to the
interest rate per year that is then applicable to the Securities on the date on
which notice of redemption is given, plus accrued and unpaid interest thereon,
if any, to, but not including, the Redemption Date (subject to the rights of
Holders on relevant Record Dates to receive interest due on an Interest Payment
Date); provided that at least 65% of the aggregate principal amount of
Securities (including Additional Securities) remains outstanding immediately
after the occurrence of such redemption; provided further that any such
redemption may not occur in connection with a Change of Control. In order to
effect the foregoing redemption, the Issuer must consummate such redemption
within 90 days of the closing of the Equity Offering.

          SECTION 3.2. Notices to Trustee.

          If the Issuer elects to redeem Securities pursuant to Paragraph 5 of
the Securities and Section 3.1 of this Indenture, it 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 Issuer elects 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, it 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 Issuer in exchange for Exchange
Securities may be made the basis for such credit.

          The Issuer 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. The Trustee shall
make the selection from the Securities outstanding and not previously called for
redemption and shall promptly notify the Issuer 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;
provided that, no Securities of $2,000 or less shall be redeemed in part. The
Trustee may select for redemption portions (in integral multiples of $1,000) of
the principal of Securities that have denominations larger than $2,000.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.

          SECTION 3.4. Notice of Redemption.

          At least 30 days and not more than 60 days before a Redemption Date,
the Issuer 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
Issuer's request, the Trustee shall give the notice of redemption as prepared by
the Issuer, in the Issuer's name and at the Issuer's 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 Issuer defaults in its 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.

<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.

<PAGE>
          SECTION 3.6. Deposit of Redemption Price.

          By 10:00 a.m. on, or prior to, the Redemption Date, the Issuer shall
deposit with the Paying Agent (other than the Issuer or an Affiliate of the
Issuer) 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 Issuer to the Trustee for cancellation). The
Paying Agent shall promptly return to the Issuer any cash so deposited which is
not required for that purpose.

          If the Issuer complies 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 Issuer 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
Issuer 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 Issuer 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 Issuer on the date it is due if the Trustee or Paying
Agent (other than the Issuer or an Affiliate of the Issuer) 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
Issuer 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.

                                       50
<PAGE>

          SECTION 4.2. Maintenance of Office or Agency.

          The Issuer 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 Issuer in respect of the
Securities and this Indenture may be served. The Issuer 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 Issuer shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the address of the Trustee set forth in Section 11.2. The Issuer
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 Issuer of its
obligations to maintain an office or agency in the Borough of Manhattan, The
City of New York, for such purposes. The Issuer 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 Issuer hereby initially
designates the corporate trust office of the Trustee in New York City as such
office.

          SECTION 4.3. Limitation on Restricted Payments.

          The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any Restricted Payment, if,
immediately prior or after giving effect thereto (a) a Default or an Event of
Default would exist (b) the Issuer would not be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Annual Debt to EBITDA Ratio
provision set forth in the second paragraph of Section 4.10, or (c) the
aggregate amount of all Restricted Payments made by the Issuer and its
Restricted Subsidiaries, including such proposed Restricted Payment (if not made
in cash, then the Fair Market Value of any property used therefor) from and
after the Issue Date and on or prior to the date of such Restricted Payment,
shall exceed the sum of (i) the amount determined by subtracting (x) 1.65 times
the aggregate Consolidated Interest Expense of the Issuer for the period (taken
as one accounting period) from the first day of the quarter commencing
immediately prior to the Issue Date to the last day of the last full fiscal
quarter prior to the date of the proposed Restricted Payment (the "Computation
Period") from (y) Consolidated EBITDA of the Issuer for the Computation Period,
(ii) the aggregate Net Proceeds received by the Issuer from the sale (other than
to a Subsidiary of the Issuer) of its Qualified Capital Stock after the Issue
Date and on or prior to the date of such Restricted Payment (and in any case
other than Excluded Contributions, Excluded Cash Contributions and Investment
Equity), (iii) 100% of the aggregate amount of non-recourse contributions to the
capital of the Issuer and its Restricted Subsidiaries since the Issue Date (in
any case other than Excluded Contributions, Excluded Cash Contributions and
Investment Equity), (iv) to the extent not otherwise included in clauses (i) -
(iii) above, an amount equal to the net reduction in Investments in Unrestricted
Subsidiaries resulting from payments of dividends, repayment of loans or
advances, or other transfers of assets, in each case to the Issuer or any
Restricted Subsidiary 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 Issue Date and (v)
$30,000,000.

          Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph will not prohibit the actions described below
(i) the payment of any dividend within 60 days after the date of its declaration
if such dividend could have been made on the date of its declaration in
compliance with the foregoing provisions, (ii) the redemption, defeasance,
repurchase or other acquisition or retirement of any Subordinated Indebtedness
or Capital Stock of the Issuer or its Restricted Subsidiaries either in exchange
for or out of the Net Proceeds of the substantially concurrent sale (other than
to a Subsidiary of the Issuer) of Qualified Capital Stock (in the case of any
redemption, defeasance, repurchase or other acquisition or retirement of Capital
Stock of the Issuer or its Restricted Subsidiaries) or Subordinated
Indebtedness, (iii) the purchase, redemption or other acquisition or retirement
for value of Capital Stock of the Issuer from employees, former employees,
directors, former directors, consultants and former consultants of the Issuer or
any of its Subsidiaries pursuant to the terms of the agreements pursuant to
which such Capital Stock was acquired in an amount not to exceed $5,000,000 in
the aggregate in any calendar year (with unused amounts in any calendar year
being carried over to the next two succeeding calendar years); provided that
such amount in any calendar year may be increased by an amount not to exceed (a)
the cash proceeds from the sale of Capital Stock to members of management,
directors or consultants that occurs after the Measurement Date plus (b) the
cash proceeds of key man life insurance policies received by the Issuer and its
Restricted Subsidiaries after the Measurement Date; (iv) repurchases of Capital
Stock of the Issuer deemed to occur upon exercise of stock options if such
Capital Stock represents a portion of the exercise price of such options, (v)
the repurchase or other repayment of Indebtedness subordinated in right of
payment to the Securities upon a Change of Control or Asset Sale to the extent
required by the agreement governing such Indebtedness but only if the Issuer
shall have complied with Article X or, as the case may be, Section 4.13 and
purchased all Securities validly tendered and not withdrawn pursuant to the
relevant offer prior to purchasing or repaying such other Indebtedness; (vi) the
repurchase, redemption, defeasance, retirement, refinancing, acquisition for
value or payment of principal of any Indebtedness of the Issuer or any Guarantor
subordinated in right of payment to the Securities (other than Disqualified
Capital Stock) (a "refinancing") through the issuance of new Subordinated
Indebtedness of the Issuer or any Guarantor, 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) 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 (II)
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 Issuer or
any Guarantor, as the case may be, incurred in connection with such refinancing;
(2) has a final maturity date later than the final maturity date of, and has a
Weighted Average Life equal to or greater than the Weighted Average Life of, the
Indebtedness to be refinanced; and (3) is expressly subordinated in right of
payment to the Securities or the Guarantees, as applicable, at least to the same
extent as the Indebtedness to be refinanced; (vii) the declaration and payment
of dividends or distributions to holders of any class or series of Disqualified
Capital Stock of the Issuer or any Guarantor or any Preferred Stock of the
Issuer's Restricted Subsidiaries that are not Guarantors issued or incurred in
accordance with Section 4.10; (viii) the payment of dividends on the Issuer's
common equity interests after the Issue Date of up to 6% per annum of an amount

                                       51

<PAGE>

equal to the net cash proceeds received by the Issuer in its initial public
offering; (ix) the repurchase, retirement or other acquisition for value of
Capital Stock of the Issuer in existence on the Measurement Date (which shall
not exceed 7.1% of the outstanding Capital Stock of the Issuer prior to January
7, 1999) and which are not held by Welsh Carson, Blackstone or their respective
Affiliates or any members of management of the Issuer or its Subsidiaries
(including any Capital Stock issued in respect of such Capital Stock as a result
of a stock split, recapitalization, merger, combination, consolidation or
otherwise) provided that (A) the amount per share paid under this clause (ix)
shall not exceed $41.50 per share (as such amount shall be adjusted as
determined in good faith by the Board of Directors of the Issuer for stock
splits, stock dividends, recapitalizations, stock recombinations, mergers,
reverse stock splits, consolidations or similar transactions) and (B) after
giving effect thereto, the Issuer would be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Annual Debt to EBITDA Ratio test
contained in the second paragraph of Section 4.10; (x) Investments made with
Excluded Contributions; (xi) any payments made in connection with the
Transactions; (xii) cash payments in lieu of the issuance of fractional shares;
and (xiv) other Restricted Payments in an aggregate amount not to exceed
$30,000,000.

          In determining the aggregate amount expended for Restricted Payments
in accordance with clause (c) of the first paragraph of this Section 4.3, 100%
of the amounts expended under clauses (i), (ii) (to the extent the Net Proceeds
from the concurrent sale of Qualified Capital Stock has been added to the
aggregate Net Proceeds calculation pursuant to clause (ii) of clause (c) of the
first paragraph of this Section 4.3), (iii), (iv), (vii), (viii), (ix) and (xii)
of the immediately preceding paragraph shall be deducted from the amount of
Restricted Payments that can be made under such clause (c). For the avoidance of
doubt, in determining the aggregate amount expended for Restricted Payments in
accordance with clause (c) of the first paragraph of this Section 4.3, none of
the amounts expended under any of the clauses not referred to in the immediately
preceding sentence shall be deducted from the amount of Restricted Payments that
can be made under such clause (c).

          SECTION 4.4. Corporate and Other Existence.

          Subject to Article V, the Issuer shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate or
other existence, as the case may be, and the corporate or other existence of
each of the Issuer's Restricted Subsidiaries in accordance with the respective
organizational documents of each of them and the rights (charter and statutory)
and corporate or other franchises of the Issuer and each of the Issuer's
Restricted Subsidiaries; provided, however, that the Issuer shall not be
required to preserve, with respect to itself, any right or franchise, and with
respect to any Restricted Subsidiaries of the Issuer, any such existence, right
or franchise, if the Issuer 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 Issuer and
its Subsidiaries on a consolidated basis, the Issuer shall, and 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 the Issuer or any of its
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 the Issuer or any of its
Restricted Subsidiaries; provided, however, that the Issuer and its Restricted
Subsidiaries shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings and for
which disputed amounts adequate reserves have been established in accordance
with GAAP.

          SECTION 4.6. Maintenance of Properties and Insurance.

          The Issuer shall cause all material properties used or useful to the
conduct of its business and the business of each of the Issuer'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 Issuer and its
Restricted Subsidiaries 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 Issuer, desirable
in the conduct of the business of such entity.

          The Issuer shall provide, or cause to be provided, for itself and each
of the Issuer's Restricted Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the reasonable,
good faith opinion of the Issuer is adequate and appropriate for the conduct of
the business of the Issuer 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
Issuer as are adequate and appropriate for the conduct of the business of the
Issuer 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 the Issuer and its
Restricted Subsidiaries, taken as a whole.

          SECTION 4.7. Compliance Certificate; Notice of Default.

          (a) The Issuer shall deliver to the Trustee within 120 days after the
end of its 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 Issuer has kept, observed,
performed and fulfilled its 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 Issuer or any Subsidiary of the Issuer 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.

          (b) The Issuer 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 Issuer is 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 Issuer or
any of the Holders.

          SECTION 4.8. Reports.

          Whether or not the Issuer is subject to Section 13(a) or 15(d) of the
Exchange Act, so long as any Securities are outstanding, the Issuer will, to the
extent permitted under the Exchange Act, file with the Commission the annual
reports, quarterly reports and other documents which the Issuer would have been
required to file with the Commission pursuant to Section 13(a) or 15(d) of the
Exchange Act 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 the
Issuer would have been required to file such documents if it were so subject.
The Issuer 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 the Issuer would have been required to file with the Commission pursuant
to Section 13(a) or 15(d) of the Exchange Act as if the Issuer were subject to
either of such Sections and (y) if filing such documents by the Issuer 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 the
Issuer's cost. So long as any of the Securities remain outstanding, the Issuer
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 Issuer has
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 Transactions with Related Persons.

          The Issuer 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 $5,000,000, unless (a) such Affiliate Transaction is on terms that are not
materially less favorable, taken as a whole, to the Issuer or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable
transaction by the Issuer or such Restricted Subsidiary with an unrelated Person
and the Issuer delivers an Officers' 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 $15,000,000, the Issuer delivers to the
Trustee a resolution adopted by the majority of the Disinterested Directors
approving such Affiliate Transaction and set forth in an Officers' 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 Issuer and/or any of its Restricted
Subsidiaries; (ii) Restricted Payments permitted by the provisions of this
Indenture described above under Section 4.3 and Permitted Investments; (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) $1,000,000 or
(b) 1% of Annual Consolidated EBITDA of the Issuer; (iv) the payment of
reasonable and customary fees paid to, and indemnity provided on behalf of,
officers, directors, employees or consultants of the Issuer or any Restricted
Subsidiary, including, without limitation, payments pursuant to employment
agreements, benefit plans and similar obligations; (v) payments by the Issuer 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
Issuer in good faith; (vi) any transaction with respect to which the Issuer 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 Issuer 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
Issuer 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 materially
disadvantageous to the Holders of the Securities, taken as a whole, as
determined by the Board of Directors of the Issuer) or any transaction
contemplated thereby; (ix) the existence of, or the performance by the Issuer or
any of its Restricted Subsidiaries of its obligations under 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; (x) any payment pursuant to a tax
sharing agreement between the Issuer and any other Person with which the Issuer
is required or permitted to file a consolidated tax return or with which the
Issuer 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 Issuer and its Restricted Subsidiaries (as a consolidated,
combined or unitary group); (xi) transactions with a Person (other than an
Unrestricted Subsidiary of the Issuer) that is an Affiliate of the Issuer or any
Restricted Subsidiary solely because the Issuer or any Restricted Subsidiary
owns an equity interest in, or controls, such Person; (xii) issuances and sales
of equity interests (other than Disqualified Stock) to Affiliates of the Issuer
(other than an Unrestricted Subsidiary of the Issuer); and (xiii) any payments
made in connection with the Transactions.

          SECTION 4.10. Limitation on Incurrence of Additional Indebtedness.

          The Issuer 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 4.10, 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 Issuer and/or any Restricted
Subsidiary of the Issuer may Incur Indebtedness (including Acquired
Indebtedness) if the Issuer's Annual Debt to EBITDA 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 Issuer or any Restricted Subsidiary under one
     or more Credit Facilities in an aggregate principal amount at any one time
     outstanding not to exceed $1.0 billion, reduced by permanent reductions in
     commitments in satisfaction of the Net Cash Proceeds application
     requirement set forth in Section 4.13; provided that any Indebtedness under
     the Senior Credit Facility outstanding on the Issue Date will be deemed to
     have been incurred under this clause (i);

          (ii) Indebtedness pursuant to the Securities and the 2013 Fixed Rate
     Notes issued on the Issue Date and other Indebtedness existing on the Issue
     Date (other than under the Senior Credit Facility) and Refinancing
     Indebtedness Incurred to refinance Indebtedness incurred pursuant to this
     clause (ii);

          (iii) Indebtedness between the Issuer and any Restricted Subsidiary of
     the Issuer or between Restricted Subsidiaries of the Issuer, provided that,
     in the case of Indebtedness of the Issuer, 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 transfer to
     the Issuer 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 Issuer 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
     Issuer or 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) $100,000,000 and
     (y) 5% of the Issuer'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 Issuer or such
     Restricted Subsidiary of the property purchased or leased with the proceeds
     thereof;

          (v) Indebtedness of the Issuer 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 Issuer 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 Issuer 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 Senior Credit
     Facility or any other Indebtedness Incurred in accordance with the
     provisions of this Section 4.10 and Section 4.18;

          (vii) Indebtedness Incurred by the Issuer or any of its Restricted
     Subsidiaries in connection with the acquisition of a new Restricted
     Subsidiary (including Acquired Indebtedness) or of property, businesses or
     assets which, or Capital Stock of a Person 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 $40,000,000 in the aggregate
     at any one time outstanding;

          (viii) Indebtedness of the Issuer or any Restricted Subsidiary under
     standby letters of credit or reimbursement obligations with respect thereto
     issued in the ordinary course of business; provided that upon the drawing
     of such letters of 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 Issuer or any Restricted Subsidiary (which Indebtedness is otherwise
     permitted to be Incurred under this Section 4.10) or (B) Indebtedness for
     which a lender has provided a commitment in an amount reasonably
     anticipated to be Incurred by the Issuer or any Restricted Subsidiary in
     the 12 months after such Interest Rate Protection Obligations have been
     Incurred; provided however, that the notional principal amount of such
     Interest Rate Protection Obligations do 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
     Issuer 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 Issuer or any Restricted Subsidiary; provided however, that
     such Currency Hedging Agreements do not

                                       57

<PAGE>

     increase the Indebtedness or other obligations of the Issuer 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 Issuer or any Restricted Subsidiary of the
     Issuer (other than as otherwise permitted pursuant to this Section 4.10)
     not to exceed $125,000,000 in the aggregate at any one time outstanding;

          (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 Issuer or its Restricted Subsidiaries reasonably incurred in connection
     with such refinancing);

          (xiii) the incurrence of Indebtedness by the Issuer or any of its
     Restricted Subsidiaries arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument (except in
     the case of daylight overdrafts) drawn against insufficient funds in the
     ordinary course of business, provided, however, that such Indebtedness is
     extinguished within five business days of incurrence;

          (xiv) the incurrence of Indebtedness by the Issuer or any of its
     Restricted Subsidiaries incurred in respect of workers' compensation
     claims, self-insurance obligations, bankers' acceptances, performance,
     surety and similar bonds and completion guarantees provided by the Issuer
     or a Restricted Subsidiary, in each case, in the ordinary course of
     business; and

          (xv) other Indebtedness of the Issuer 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 Issuer or cash contributions made to the
     capital of the Issuer (other than in exchange for Disqualified Capital
     Stock); provided that the amount of such cash contributions ("Excluded Cash
     Contributions") are designated in an Officers' Certificate as Excluded Cash
     Contributions and shall not be included in the computation of the amount of
     Restricted Payments which the Issuer can make pursuant to Section 4.3.

          For purposes of determining compliance with this Section 4.10, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of permitted Indebtedness described in clauses (i) through (xv) above
or is entitled to be Incurred pursuant to the second paragraph of this covenant,
the Issuer may, in its sole discretion, classify (or later classify or
reclassify in whole or in part in its sole discretion) such item of Indebtedness
on the date of Incurrence in any manner that complies with this covenant and
such item of Indebtedness will be treated as having been Incurred pursuant to
only the designated clauses or pursuant to the second paragraph hereof; provided
that Indebtedness under any Senior Credit Facility outstanding on the Issue Date
will initially be deemed to have been incurred on such date in reliance on the
exception provided by clause (i) above. Notwithstanding any other provision of

                                       58

<PAGE>

this Section 4.10, the maximum amount of Indebtedness that the Issuer may incur
pursuant to this Section 4.10 shall not be deemed to be exceeded solely as a
result of fluctuations in the exchange rate of currencies.

          SECTION 4.11. Limitation on Restricting Subsidiary Dividends.

          The Issuer 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 to pay dividends or make other distributions on the Capital Stock of
any Restricted Subsidiary or pay or satisfy any obligation to the Issuer or any
of the Restricted Subsidiaries or otherwise transfer assets or make or pay loans
or advances to the Issuer or any of the Restricted Subsidiaries, except
encumbrances and restrictions existing under (i) any applicable law or any
governmental or administrative regulation or order; (ii) Refinancing
Indebtedness permitted under this Indenture, provided that the restrictions
contained in the instruments governing such Refinancing Indebtedness are not
materially more restrictive, taken as a whole, than those contained in the
instruments governing the Indebtedness being refinanced immediately prior to
such refinancing, as determined by the Board of Directors of the Issuer; (iii)
restrictions solely with respect to one or more Restricted Subsidiaries of the
Issuer imposed pursuant to an 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 Issuer or a Restricted Subsidiary, which restrictions existed at
the time of acquisition and any amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings of
those agreements, provided that the amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings are
not materially more restrictive, taken as a whole, with respect to such dividend
and other payment restrictions than those contained in those agreements being
refinanced, as determined by the Board of Directors of the Issuer; (vi)
contractual encumbrances or restrictions in effect on the Issue Date (including,
without limitation, encumbrances and restrictions relating to the Senior Credit
Facility, the 2013 Senior Notes, the 2014 Senior Notes or the 2008 Senior
Subordinated Notes or any other Indebtedness outstanding on the Issue Date) and
encumbrances and restrictions contained in the security agreements related to
the Senior Credit Facility each case as such encumbrances or restrictions may be
amended, provided that such encumbrances or restrictions as amended are not
materially more restrictive, taken as a whole, than those contained in
contractual encumbrances or restrictions in effect on the Issue Date, as
determined by the Board of Directors of the Issuer; (vii) contractual
encumbrances or restrictions contained in other Indebtedness of CCOC, or any
Restricted Subsidiary permitted to be incurred pursuant to an agreement entered
into subsequent to the Issue Date in accordance with Section 4.10 provided that
the provisions relating to such encumbrance or restriction contained in such
Indebtedness are not materially less favorable to the Issuer, taken as a whole,
as determined by the Board of Directors of the Issuer than the provisions
contained in the Senior Credit Agreement or in the indentures governing the 2013
Senior Notes or the 2014 Senior Notes or the 2008 Senior Subordinated Notes, in
each case, as in effect on the Issue Date; (viii) this Indenture, the Fixed Rate
Indenture, the Securities and the 2013 Fixed Rate Securities; (ix) Purchase

relates to the property underlying the Purchase Money Indebtedness; (x)
Indebtedness of Restricted Subsidiaries otherwise permitted to be Incurred
pursuant to Section 4.10 and Section 4.12; (xi) 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; provided that the
Annual Consolidated EBITDA, 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 restrictions does not exceed
10% of the Issuer's Annual Consolidated EBITDA on the date of execution of such
joint venture or similar agreement; or (xii) customary provisions restricting
subletting or assignment of any lease entered into in the ordinary course of
business.

          SECTION 4.12. Limitation on Liens.

          The Issuer will not, and will not cause or permit any Restricted
Subsidiary to, directly or indirectly, create or Incur any Lien of any kind
(other than a Permitted Lien) securing any Indebtedness of the Issuer (other
than Indebtedness with respect to which CCOC and/or Centennial PR are
co-obligors) (including any assumption, guarantee or other liability with
respect thereto by any Restricted Subsidiary) upon any property or assets of the
Issuer 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 (i) in the case of Liens securing Pari Passu Indebtedness, the Securities
are secured equally and ratably with the Indebtedness secured by such Lien and
(ii) in the case of Liens securing Indebtedness that is expressly subordinate or
junior in right of payment to the Securities, on a senior basis to the
obligations so secured with the same relative priority as the Securities will
have to that subordinate or junior Indebtedness. Notwithstanding the foregoing,
any Lien securing the Securities granted pursuant to this Section 4.12 shall be
automatically and unconditionally released and discharged, without any further
action on behalf of the Holders, upon the release by the holders of the
Indebtedness described above of their Lien on the property or assets of the
Issuer 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 Issuer or such Restricted Subsidiary, or upon any sale, exchange or transfer
to any Person of the property or assets secured by such Lien, or of all of the
Capital Stock held by the Issuer or any Restricted Subsidiary in, or all or
substantially all the assets of, any Restricted Subsidiary creating such Lien.

          SECTION 4.13. Limitation on Asset Sales and Sales of Subsidiary Stock.

          The Issuer 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, whether by the Issuer or a
Restricted Subsidiary other than any single transaction or a series of related
transactions that involves properties, businesses or assets having a Fair Market
Value of less than $10,000,000, as determined in good faith by the Issuer's
Board of Directors (an "Asset Sale"), unless (1) either (a) within 395 days of
such Asset Sale, an amount equal to the Net Cash Proceeds therefrom (the "Asset
Sale Offer Amount") are applied to the repurchase of the Securities and other
Indebtedness of the Issuer ranking on a parity with the Securities from time to
time outstanding (including the 2013 Fixed Rate Securities, the 2013 Senior
Notes and the 2014 Senior Notes) with similar provisions requiring the Issuer or
a Restricted Subsidiary of the Issuer to make an offer to purchase such
Indebtedness with the proceeds from asset sales 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 395 days of such Asset Sale, or (b) within 395 days of
such Asset Sale, the Asset Sale Offer Amount is (i) invested (or committed,
pursuant to a binding commitment subject only to reasonable closing conditions,
to be invested, and in fact 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 Issuer are of a type used in
a Related Business, or Capital Stock of a Person (which, if such Person becomes
a Subsidiary of the Issuer 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 Issuer) 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 third paragraph
of this Section 4.13 shall have been satisfied), (ii) used to permanently retire
Indebtedness of the Issuer or any Guarantor that is, in each case, Pari Passu
Indebtedness or Priority Indebtedness, or (iii) used to permanently retire
Indebtedness of CCOC or Centennial PR or any Restricted Subsidiary of CCOC or
Centennial PR (including Indebtedness with respect to which the Issuer is a
co-obligor), (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 $5,000,000, at least 75% of the value of consideration for
the assets disposed of in such Asset Sale (excluding (a) Indebtedness of the
Issuer 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 4.10 (including that in the case of a revolving credit facility 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 converted into cash or Cash Equivalents within
180 days and (d) tangible assets and property (other than notes, obligations or
securities), which in the good faith reasonable judgment of the Board of
Directors of the Issuer are of a type used in a Related Business), 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 an amount equal to the Net Cash
Proceeds of any such Asset Sale as set forth above (provided further that the
Issuer 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 Issuer determines in good faith that the
Issuer 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 an amount equal to the
accumulated Net Cash Proceeds from Asset Sales not applied to the uses set forth
in (1)(b) above exceeds $20,000,000, such amount not used for purposes permitted
and within the time period by this Section 4.13 being referred to as the
"Accumulated Amount". 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 Issuer shall apply the Asset Sale Offer Amount, plus an
amount equal to accrued interest to, but not including, the date of 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 two paragraphs
and subparagraphs (1), (2) and (3) above:

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

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

          (iii) the Issuer 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 Issuer or such Restricted Subsidiary, as
     applicable;

          (iv) the Issuer and its Restricted Subsidiaries may convey, sell,
     lease, transfer, assign or otherwise dispose of assets to the Issuer or any
     of its Restricted Subsidiaries; and

          (v) the Issuer 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 Issuer or such Restricted Subsidiary of the proposed transaction), all
     or a portion of its property, businesses or assets for property, businesses
     or assets or Capital Stock of a Person all or substantially all of whose
     assets, which are of a type used in the business of the Issuer 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 Issuer 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 Issuer shall have
     approved a resolution of the Board of Directors that

                                       62

<PAGE>

     such exchange is fair to the Issuer 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
     subparagraphs (1), (2) and (3) of this Section 4.13; 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 Issuer or a Restricted
     Subsidiary and, when combined with the Capital Stock of such Person already
     owned by the Issuer 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.

          For purposes of this Section 4.13, "Minimum Accumulation Date" means
each date on which the Accumulated Amount exceeds $20,000,000. Not later than 10
Business Days after each Minimum Accumulation Date, the Issuer will, subject to
its election pursuant to clause (1) of the first paragraph of this Section,
commence an Asset Sale Offer to the Holders and holders of other Indebtedness of
the Issuer ranking pari passu in right of payment with the Securities from time
to time outstanding with similar provisions requiring the Issuer 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, but not 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 not later than 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 Issuer 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 4.13;

                                       63

<PAGE>

               (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;

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

               (D) that, unless the Issuer defaults in depositing cash with the
          Paying Agent in accordance with the penultimate paragraph of this
          Section 4.13 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 4.13,
          notwithstanding anything this Indenture to the contrary, be the Issuer
          or any Affiliate of the Issuer) at the address specified in the notice
          prior to the close of business on the Final Put Date;

               (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 4.13, notwithstanding any other provision of this
          Indenture, be the Issuer or any Affiliate of the Issuer) 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 Issuer 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 Issuer 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 Issuer 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

                                       64

<PAGE>

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 Issuer. 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 Issuer 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
Issuer or any Holder.

                                       65

<PAGE>
          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 4.13 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 Issuer 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 4.14. Waiver of Stay, Extension or Usury Laws.

          The Issuer covenants (to the extent that it may lawfully do so) that
it 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 Issuer 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 Issuer hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

          SECTION 4.15. [INTENTIONALLY OMITTED].

          SECTION 4.16. Limitation on Unrestricted Subsidiaries.

          The Issuer may designate any Subsidiary 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 Issuer 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 Issuer's interest in such
     Subsidiary calculated in accordance with GAAP and (2) the Fair Market Value
     of the Issuer's interest in such Subsidiary as determined in good faith by
     the Issuer's Board of Directors;

          (c) such Unrestricted Subsidiary does not own any Capital Stock in any
     Restricted Subsidiary 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 Issuer or any
     Restricted Subsidiary unless the terms of any such agreement, contract,
     arrangement or understanding are no less favorable to the Issuer or such
     Restricted Subsidiary than those that might be obtained at the time from
     Persons who are not Affiliates of the Issuer 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.

          In the event of any such Designation, the Issuer 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 Issuer 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 Investments that are permissible
under Section 4.3) 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 Issuer as an Unrestricted Subsidiary shall be deemed to
be the Designation of all of the Subsidiaries of such Subsidiary as Unrestricted
Subsidiaries.

          The Issuer 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 would be 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 Issuer could
     Incur $1.00 of additional Indebtedness (other than Permitted Indebtedness)
     pursuant to Section 4.10.

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

          SECTION 4.17. Limitation on Lines of Business.

          Neither the Issuer 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 Issuer, is a Related Business.

                                       68

<PAGE>
          SECTION 4.18. Limitation on Issuance of Guarantees; Release of
Guarantee.

          (a) The Issuer 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 Issuer or any Guarantor (other than under the Senior Credit
Facility or any Indebtedness of the Issuer with respect to which CCOC or a
Restricted Subsidiary of CCOC is a co-issuer) 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 4.12 and 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 2013 Senior Notes, the 2014 Notes or
the 2008 Senior Subordinated 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 4.10.

          (b) Notwithstanding the foregoing, any Guarantee by a Restricted
Subsidiary of the Securities shall provide by its terms that it (and all Liens
securing the same) shall be automatically and unconditionally released, without
any action on the part of the Holders of the Securities, and discharged upon (i)
any direct or indirect sale, exchange or transfer, to any Person of all or
substantially all the assets of such Restricted Subsidiary, or upon a direct or
indirect sale or transfer of capital stock of such Guarantor, as a result of
which such Guarantor ceases to be a Subsidiary of the Issuer, or upon the
designation of such Guarantor as an Unrestricted Subsidiary in accordance with
the provisions of this Indenture which transaction is otherwise in compliance
with the terms of this Indenture or (ii) the release by the holders of the
Indebtedness of the Issuer or any Guarantor described in clause (a) above of
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 Issuer or any Guarantor, as applicable, 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);
provided that this clause (b) of this Section 4.18 will continue to be
applicable from and after any Investment Grade Date.

          SECTION 4.19. Waiver of Compliance with Certain Covenants.

          The Issuer may omit in any particular instance to comply with any
covenant or condition set forth in Sections 4.3 and 4.8 through 4.18 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 Issuer and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect.

<PAGE>
          SECTION 4.20. Termination of Certain Covenants

          Notwithstanding anything in this Indenture to the contrary, from and
after the first date after the Issue Date on which the Securities have an
Investment Grade Rating and no Default or Event of Default has occurred and is
continuing (the "Investment Grade Date"), the Issuer and the Restricted
Subsidiaries will no longer be subject to the provisions of Sections 4.3, 4.9,
4.10, 4.11, 4.12, 4.13, 4.16, 4.17 and 4.18 (with regards to Section 4.18,
except as set forth therein) and clause (iii) of Section 5.1.

          SECTION 4.21. Investment Grade Covenant

          From and after any Investment Grade Date, the following covenant will
apply to the Issuer and its Subsidiaries and become effective upon such
Investment Grade Date:

     Secured Indebtedness

          If the Issuer or any Subsidiary incurs any Indebtedness secured by a
Lien (other than a Permitted Lien) on any Principal Property or on any share of
stock or Indebtedness of a Subsidiary, the Issuer or such Subsidiary, as the
case may be, will secure the Securities equally and ratably with (or, at its
option, prior to) the Indebtedness so secured until such time as such
Indebtedness is no longer secured by a Lien, unless the aggregate amount of all
Indebtedness secured by a Lien and the Attributable Amount of all Sale/Leaseback
Transactions involving Principal Property would not exceed 15% of Consolidated
Net Tangible Assets.

                                   ARTICLE V
                              SUCCESSOR CORPORATION

          SECTION 5.1. Limitation on Merger, Sale or Consolidation.

          The Issuer 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 Issuer 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
Issuer on a consolidated basis, unless (i) either (a) the Issuer 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 or the Commonwealth of Puerto Rico and expressly assumes by
supplemental indenture all of the obligations of the Issuer 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 Issuer or any of its Restricted Subsidiaries which becomes
the obligation of the Issuer 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 internally 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 Issuer or
the resulting surviving or transferee entity would immediately thereafter be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Annual Debt to EBITDA Ratio provision set forth in the second paragraph of
Section 4.10, or such Annual Debt to EBITDA Ratio would be lower than such ratio
immediately prior to such transaction; provided that this clause (iii) will no
longer be applicable from and after any Investment Grade Date; (iv) at the time
of the transaction described above, each Guarantor, if any, unless it is the
other party to the transaction described above, will have by supplemental
indenture confirmed that its Guarantee shall apply to such Person's obligations
under this Indenture and the Securities; and (v) at the time of the transaction
described above, the Issuer 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, (1) any Restricted Subsidiary may merge
with and into any other Restricted Subsidiary or the Issuer and (2) the Issuer
may merge with an Affiliate incorporated solely for the purpose of
reincorporating the Issuer in another jurisdiction.

          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 Issuer in accordance with the
foregoing, the successor entity formed by such consolidation or into which the
Issuer 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 Issuer under
this Indenture with the same effect as if such successor entity had been named
herein as the Issuer and the Issuer shall be released from the obligations under
the Securities, this Indenture and the Registration Rights Agreement.

                         EVENTS OF DEFAULT AND REMEDIES

          SECTION 6.1. Events of Default.

          "Event of Default," wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be caused voluntarily or involuntarily or effected, without limitation, by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

               (1) the failure by the Issuer to pay any installment of interest
          or Additional Interest, if any, on the Securities as and when the same
          becomes due and payable and the continuance of such failure for 30
          days;

               (2) the failure by the Issuer to pay all or any part of the
          principal, or premium, if any, on the Securities when and as the same
          becomes due and payable at maturity, redemption, by acceleration or
          otherwise, including, without limitation, payment of the Change of
          Control Purchase Price in accordance with Article X or the Asset Sale
          Offer Price in accordance with Section 4.13;

               (3) the failure by the Issuer to observe or perform any other
          covenant or agreement contained in the Securities or this Indenture
          (other than a default in the performance of any covenant or agreement
          which is specifically dealt with elsewhere in this Section 6.1), and
          the continuance of such failure for a period of 30 days after written
          notice is given to the Issuer by the Trustee or to the Issuer and the
          Trustee by Holders of at least 25% in aggregate principal amount of
          the Securities outstanding, specifying such default or breach,
          requiring it to be remedied and stating that such notice is a "Notice
          of Default" hereunder;

               (4) there shall have been the entry by a court of competent
          jurisdiction of (a) a decree or order for relief in respect of the
          Issuer or any Significant Restricted Subsidiary in an involuntary case
          or proceeding under any applicable Bankruptcy Law or (b) a decree or
          order adjudging he Issuer or any Significant Restricted Subsidiary
          bankrupt or insolvent, or seeking reorganization, arrangement,
          adjustment or composition of or in respect of the Issuer or any
          Significant Restricted Subsidiary under any applicable federal or
          state law, or appointing a Custodian, receiver, liquidator, assignee,
          trustee, sequestrator (or other similar official) of the Issuer or any
          Significant Restricted Subsidiary or of any substantial part of their

          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
Issuer (and to the Trustee if given by the 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
Senior 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 Sections
6.1(4) and (5) with respect to the Issuer, any 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 Senior
Credit Facility and (y) the acceleration of any Indebtedness under the Senior
Credit Facility. If an Event of Default specified in Sections 6.1(4) and (5)
above relating to the Issuer, any 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.

                                       73

<PAGE>

          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 Issuer and the Trustee, may rescind, on behalf of all
Holders, any such declaration of acceleration if:

               (A) the Issuer has 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 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 10.1.

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 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.

<PAGE>

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

          The Issuer covenants 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 Issuer 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 Issuer fails 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 Issuer 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 Issuer 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 Issuer or any other obligor upon the
Securities or the property of the Issuer or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Issuer for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise, 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 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 Issuer.

          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 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.

<PAGE>

          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.

          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

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 VIII, 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

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 Issuer, 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).

          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 Issuer, 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

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.

               (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 Issuer.
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 11.4 and 11.5. 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. The Trustee may consult with counsel of its
selection, and the advice or opinion of such counsel as to matters of law shall
be full and complete authorization and protection from liability in respect of
any action taken, omitted or suffered by it hereunder in good faith and in
accordance with the advice or opinion of such 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. The Trustee shall not be required to
give any bond or surety in respect of the performance of its powers and duties
hereunder.

          (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 Issuer
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 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 Issuer shall be sufficient if
signed by an Officer of the Issuer.

          (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. Delivery of reports, information and documents
to the Trustee under Section 4.8 is for informational purposes only and the
Trustee's receipt of the foregoing shall not constitute constructive notice of
any information contained therein, including the Issuer's compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively
on an Officers' Certificate).

          (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 Issuer or any of
the Issuer'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.

                                       81

          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 Issuer'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 the later of 90 days
after such Default or Event of Default occurs or 30 days after it actually is
known by the Trustee. 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.

          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 Issuer 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 Issuer and filed with the Commission and each stock
exchange, if any, on which the Securities are listed.

                                       82

          SECTION 7.7. Compensation and Indemnity.

          The Issuer agrees 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 Issuer 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 Issuer agrees 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 Issuer promptly of any claim asserted
against the Trustee for which it may seek indemnity. The Issuer 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 Issuer's 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 Issuer's obligations under this Section 7.7 and any lien arising
hereunder shall survive the resignation or removal of the Trustee and any
rejection or termination of this Indenture under any Bankruptcy Law.

          SECTION 7.8. Replacement of Trustee.

          The Trustee may resign by so notifying the Issuer in writing. The
Holder or Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Issuer and the Trustee in
writing and may appoint a successor trustee with the Issuer's consent. The
Issuer 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 Issuer 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 Issuer. A successor
Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Issuer. 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 Issuer 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 Issuer's 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
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

          SECTION 7.10. Eligibility; Disqualification.

          The Trustee shall at all times satisfy the requirements of TIA Section
310(a)(1), (2) and (5). The Trustee shall have a combined capital and surplus of
at least $10,000,000 as set forth in its most recent published annual report of
condition. The Trustee shall comply with TIA Section 310(b).

          SECTION 7.11. Preferential Collection of Claims Against the Issuer.

          The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated.

                                       84

          SECTION 7.12. Wire Transfers and Investments.

          (a) The Trustee shall be authorized to seek confirmation of fund
transfer instructions by telephone call-back to the person or persons designated
on Exhibit E hereto, and the Trustee may rely upon the confirmations of any one
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
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 8.1. Supplemental Indentures Without Consent of Holders.

          Without the consent of any Holder, the Issuer, 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 the Issuer or
          a Guarantor, and the assumption by any such successor of the covenants
          of the Issuer 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 the Issuer, any Guarantor, any
          Restricted Subsidiary 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 the Issuer, any Guarantor, any Restricted
          Subsidiary 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;

               (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 or release 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
          this 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
          the Issuer'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.

                                       85

<PAGE>

          SECTION 8.2. 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 Issuer and the Trustee, the Issuer, 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 Issuer with any provision of this Indenture or the Securities.
Notwithstanding any of the above, however, without the consent of each Holder of
an outstanding Security affected, no amendment, supplemental indenture or waiver
may:

               (A) change the Stated Maturity of, 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 alter the
          redemption provisions, 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 Holder;

               (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 the Issuer 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.

                                       86

<PAGE>

          It shall not be necessary for the consent of the Holders under this
Section 8.2 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 8.2
becomes effective, the Issuer shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuer 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 8.2 or
Section 8.4 becomes effective, it shall bind each Holder.

          In connection with any amendment, supplement or waiver under this
Article IX, the Issuer 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.

                                       87

<PAGE>

          SECTION 8.3. Compliance with TIA.

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

          SECTION 8.4. 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 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
Issuer or the Person designated by the Issuer as the Person to whom consents
should be sent if such revocation is received by the Issuer 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 Issuer 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 Issuer
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
(A) through (E) of Section 8.2, 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 8.5. 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 Issuer or the Trustee
so determines, the Issuer 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.

                                       88

<PAGE>

          SECTION 8.6. Trustee to Sign Amendments, Etc.

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article VIII; 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, supplement or waiver authorized pursuant to this Article VIII is
authorized or permitted by this Indenture and all conditions precedent to such
amendment, supplement or waiver as required hereunder, have been duly satisfied.

                                   ARTICLE IX
                                FUTURE GUARANTEES

          SECTION 9.1. Future Guarantees. Any Person that becomes a Guarantor,
jointly and severally, fully, unconditionally and irrevocably guarantees as
primary obligors and not merely as a sureties, the obligations of the Issuer
under the Securities and this Indenture, and guarantees 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 Issuer 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 Issuer 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 Issuer under this Indenture and the
Securities which may be extended or renewed, in whole or in part, without notice
or further assent from such

                                       89

<PAGE>
Guarantor and that such Guarantor will remain bound under this Article IX,
notwithstanding any extension or renewal.

          Each Guarantor agrees 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 Issuer, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor.

          Each Guarantor 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 Issuer, any right to require a
proceeding first against the Issuer 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. Each
Guarantor acknowledges that the Guarantee is a guarantee of payment and not of
collection.

          Each Guarantor agrees 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 Guarantors to enforce
such Guarantor's Guarantee without first proceeding against the Issuer or any
other Guarantor, if any. Each 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 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 Issuer or any Guarantor, or any custodian, trustee, liquidator or
other similar official acting in relation to either the Issuer 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. Each 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 IX, 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 Issuer for liquidation,
dissolution or reorganization, should the Issuer 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 Issuer's 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 Article
IX shall constitute a guarantee by any Guarantor of any obligations of the
Issuer under the Securities and this Indenture.

          SECTION 9.2. Supplemental Indenture. Any Person that chooses or is
required to become 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 VIII of this Indenture, pursuant to which such
Person shall agree to guarantee the Securities and the obligations of the Issuer
thereunder and hereunder in accordance with the provisions of this Article IX
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, each reference to the "Guarantor" in this Indenture
shall be deemed to refer to such Person and all other Guarantors. If more than
one Guarantor exists at any time hereafter, the obligations of all such
Guarantors shall be joint and several.

          SECTION 9.3. Limitation of Guarantors' Liability. Each Guarantor, and
by its acceptance hereof, each Holder confirms that it is the intention of all
such parties that the Guarantee by each 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,
each of the Holders and each Guarantor 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 9.4. Subrogation. Each Guarantor shall be subrogated to all
rights of Holders against the Issuer in respect of any amounts paid by any
Guarantor pursuant to the provisions of Section 9.1; 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 Issuer under
this Indenture or the Securities shall have been paid in full.

          SECTION 9.5. Benefits Acknowledged. Each 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 9.6. Contribution. Each 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.

                           RIGHT TO REQUIRE REPURCHASE

          SECTION 10.1. 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 Issuer (the "Change of Control Offer"), to require the Issuer 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 50 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, but not including, 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 "Change of Control Offer Period"). Upon
expiration of the Change of Control Offer Period, the Issuer shall purchase all
Securities properly tendered in response to the Change of Control Offer.
Notwithstanding the foregoing, the Issuer will not be required to make a Change
of Control Offer if, upon a Change of Control, a third party (A) makes an offer
to purchase Securities in the manner, at the times and otherwise in compliance
with the requirements set forth in this Article X and (B) purchases all
Securities validly tendered and not withdrawn under such offer to purchase.

          (b) In the event that, pursuant to this Section 10.1, the Issuer shall
be required to commence a Change of Control Offer, the Issuer shall follow the
procedures set forth in this Section 10.1 as follows:

               (A) the Issuer 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 Issuer or the Trustee (upon the request and at the expense of the
          Issuer) 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 10.1 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 Issuer defaults 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 10.1, notwithstanding anything
     in this Indenture to the contrary, be the Issuer or any Affiliate of the
     Issuer) 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 10.1, notwithstanding anything in this Indenture to the contrary,
     be the Issuer or any Affiliate of the Issuer) receives, up to the close of
     business (5:00 p.m. New York Time) on the 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.

                                       92

<PAGE>

          On or before the Change of Control Purchase Date, the Issuer will (i)
accept for payment Securities or portions thereof properly tendered and not
validly withdrawn 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 to, but not including, the Change of
Control Purchase Date) 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 Issuer. 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 to, but not including, the Change of Control
Purchase Date), 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 Issuer to the Holder thereof. The Issuer
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 Issuer may modify a Change of Control Offer
to the extent necessary to effect such compliance.

                         CENTENNIAL COMMUNICATIONS CORP.

                       Senior Floating Rate Note due 2013

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

1.   Interest.

          Centennial Communications Corp., a Delaware corporation (hereinafter
called the "Issuer," which term includes any successors under the Indenture),
promises to pay interest on the principal amount of this Security at the rate
and in the manner specified below. Interest will accrue at a rate per annum,
reset quarterly, equal to LIBOR plus 5.75% as determined by the calculation
agent (the "Calculation Agent"), which shall initially be the trustee and will
be payable quarterly in arrears in cash on January 1, April 1, July 1 and
October 1 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 __________,
_____, to Holders of the Securities at the close of business on the immediately
preceding December 15, March 15, June 15 and September 15, whether or not such
date is a Business Day (each, a "Record Date").

          Interest shall accrue from the most recent date to which interest has
been paid or, if no interest has been paid, from and including the Issue Date.
To the extent lawful, the Issuer shall pay interest on overdue principal at the
rate of the then applicable interest rate on the Securities; it shall pay
interest on overdue installments of interest (without regard to any applicable
grace periods) at the same rate to the extent lawful.

          The amount of interest for each day that the Securities are
outstanding (the "Daily Interest Amount") will be calculated by dividing the
interest rate in effect for such day by 360 and multiplying the result by the
principal amount of the Securities. The amount of interest to be paid on the
Securities for each Interest Period will be calculated by adding the Daily
Interest Amounts for each day in the Interest Period. All percentages resulting
from any of the above calculations will be rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point, with five one-millionths of a
percentage point being rounded upwards (e.g., 9.876545% (or .09876545) being
rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting
from such calculations will be rounded to the nearest cent (with one-half cent
being rounded upwards). The interest rate on the Securities will in no event be
higher than the maximum rate permitted by New York law as the same may be
modified by United States law of general application. The Calculation Agent
will, upon the request of the Holder of any Securities, provide the interest
rate then in effect with respect to the Securities. All calculations made by the
Calculation Agent in the absence of manifest error will be conclusive for all
purposes and binding on the Issuer and the Holders of the Securities.

                                       A-4

<PAGE>

2.   Method of Payment.

          The Issuer 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 Issuer 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 Issuer may pay principal and
interest by wire transfer of Federal funds, or interest by its check payable in
such U.S. Legal Tender. The Issuer may deliver any such interest payment to the
Paying Agent or the Issuer 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 Issuer may change any Paying Agent, Registrar or
co-Registrar without notice to the Holders. The Issuer or any of its
Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar
or co-Registrar.

4.   Indenture.

          The Issuer issued the Securities under an Indenture, dated as of
December 21, 2005 (the "Indenture"), between the Issuer 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 Issuer initially issued
in an aggregate principal amount to $350,000,000. The Indenture pursuant to
which this Security is issued provides for 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
January 1, 2008, at the option of the Issuer, in whole or in part, on not less
than 30 nor more than 60 days' prior notice, in amounts of $1,000 or an integral
multiple thereof; provided that, no holdings of Securities of $2,000 or less
shall be redeemed in part, at the following Redemption Prices (expressed as
percentages of the principal amount), if redeemed during the 12 month period
beginning January 1 of the years indicated below:

<TABLE>
<CAPTION>
                         Redemption
         Year               Price

<S>                      <C>
2008..................     103.00%
2009..................     102.00%

</TABLE>

                                       A-5

<PAGE>

in each case, together with accrued and unpaid interest, if any, and Additional
Interest to, but not including, the Redemption Date (subject to the rights of
Holders on relevant Record Dates to receive interest due on an Interest Payment
Date).

          In addition, at any time prior to January 1, 2008, the Issuer, at its
option, may use the net cash proceeds of one or more 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 issued under
the Indenture (including any Additional Securities) at a Redemption Price equal
to 100.0% of the aggregate principal amount thereof, plus a premium equal to the
interest rate per year that is then applicable to the Securities on the date on
which notice of redemption is given, plus accrued and unpaid interest thereon,
to, but not including, the Redemption Date (subject to the rights of Holders 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 (including any Additional Securities) remains outstanding immediately
after the occurrence of such redemption; provided further that any such
redemption may not occur in connection with a Change of Control. In order to
effect the foregoing redemption, the Issuer must consummate such redemption
within 90 days of the closing of the Equity Offering.

          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. The
Securities may be redeemed in part in multiples of $1,000 only; provided that,
no holdings of Securities of $2,000 or less shall be redeemed in part.

          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 to 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 minimum
denominations of $2,000 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

                                       A-6

<PAGE>

transfer of or exchange any Securities selected for redemption prior to 15 days
after the notice of redemption.

8.   Persons Deemed Owners.

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

9.   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 Issuer. After that, all liability of the Trustee and such Paying Agent(s)
with respect to such money shall cease.

10.  Discharge Prior to Redemption or Maturity.

          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 within the remaining
term of the then current Interest Period) or are to be called for redemption
within one year (or within the remaining term of the then current Interest
Period), and in either event the Issuer has deposited with the Trustee an amount
in United States dollars sufficient to pay and discharge all of the Securities,
(b) the Issuer has paid all other sums payable under the Indenture by it and (c)
the Issuer has delivered an Officers' Certificate and Opinion of Counsel related
thereto.

11.  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.

12.  Restrictive Covenants.

          The Indenture imposes certain limitations on the ability of the Issuer
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 Issuer. The limitations are subject to a number of important
qualifications and exceptions. The Issuer must periodically report to the
Trustee on compliance with such limitations.

                                       A-7

<PAGE>

13.  Repurchase at Option of Holder.

          (a) If there is a Change of Control, the Issuer 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, but
not including, the Change of Control Purchase Date. Holders of Securities will
receive a Change of Control Offer from the Issuer 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.
Notwithstanding the foregoing, the Issuer will not be required to make a Change
of Control Offer if, upon a Change of Control, a third party (A) makes an offer
to purchase Securities in the manner, at the times and otherwise in compliance
with the requirements set forth in Article X of the Indenture and (B) purchases
all Securities validly tendered and not withdrawn under such offer to purchase.

          (b) The Indenture imposes certain limitations on the ability of the
Issuer 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 Issuer 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.

14.  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.

15.  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.

16.  Trustee Dealings with Issuer.

          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 Issuer or its
Affiliates, and may otherwise deal with the Issuer or its Affiliates as if it
were not the Trustee.

                                       A-8

<PAGE>

17.  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 Issuer or any successor entity or any
Affiliate thereof shall have any personal liability in respect of the
obligations of the Issuer 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.

18.  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.

19.  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).

20.  CUSIP Numbers.

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer 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.

21.  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 December 21, 2005, between the Issuer
and Credit Suisse First Boston LLC. In the case of Additional Securities,
Holders of Securities shall have the rights set forth in one or more
registration rights agreements with the Issuer, if any (collectively, the
"Registration Rights Agreement").
