Agreement, as applicable.

      Obligor shall pay interest on this Mirror Note to Holder one Business Day
prior to or on each CCI Interest Payment Date, except as provided in Section
2.01(b) with respect to Mirror Deferred Interest and in Section 2.06 hereof with
respect to defaulted interest. Mirror Liquidated Damages shall be payable as
described in Section 2.03 hereof. This Mirror Note shall be payable as to

                            REDEMPTION AND PREPAYMENT

Section 3.01. Redemption.

            Upon redemption by Holder of all or any portion of the CCI Notes
pursuant to Section 3.07 of the Indenture, Obligor shall redeem all or, as the
case may be, a portion of this Mirror Note in a Mirror Accreted Principal Amount
equal to the CCI Accreted Principal Amount of the CCI Notes so redeemed, at the
Mirror Repurchase Price described in Section 7.02 hereof.

Section 3.02. Payment of Mirror Redemption Price.

      At or prior to 9:30 a.m., New York City time on the Mirror Repurchase
Date, Obligor shall pay to Holder the Mirror Redemption Price of, and any
accrued and unpaid interest, Mirror Deferred Interest and Mirror Liquidated
Damages on, the Mirror Accreted Principal Amount of this Mirror Note to be
redeemed on such Mirror Repurchase Date.

      If Obligor complies with the provisions of the preceding paragraph, on and
after the Mirror Repurchase Date, interest shall cease to accrue on the portion
of the Mirror Accreted Principal Amount of this Mirror Note to which such
applies. If any of the CCI Notes are redeemed on or after a Regular Record Date
under the Indenture but on or prior to the related Mirror Interest Payment Date,
and any accrued and unpaid interest is paid to the holders of such CCI Notes by
Holder at the close of business on such Regular Record Date pursuant to the
Indenture, then Obligor shall pay to Holder interest on this Mirror Note in an
amount equal to the amount paid by Holder to the holders of such CCI Notes. If
Holder fails to redeem any CCI Notes in accordance with Section 3.05 of the
Indenture and, as a result, interest on such CCI Notes accrues and becomes
payable at the rate described in Section 3.05 of the Indenture, then interest
payable by Obligor to Holder hereunder on a Mirror Accreted Principal Amount
hereof corresponding to the aggregate CCI Accreted Principal Amount of the
affected CCI Notes shall likewise accrue and become payable by Obligor to Holder
at the rate described in Section 3.05 of the Indenture, for so long as interest
on such CCI Notes remains payable at such rate.

Mirror Liquidated Damages, if any, and interest (including any Mirror Deferred
Interest) on this Mirror Note on the dates and in the manner provided herein.

if any, Mirror Liquidated Damages, if any, and interest then due.

Section 4.02. Limited Liability Company Existence.

      Subject to Article 5, Obligor shall do or cause to be done all things
necessary to preserve and keep in full force and effect (i) its limited
liability company existence, and the corporate, partnership or other existence
of each of its Significant Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of
Obligor or any such Significant Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of Obligor and its Significant Subsidiaries;
provided, however, that Obligor shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any of its Significant Subsidiaries, if the Manager shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
Obligor and its Significant Subsidiaries, taken as a whole, and that the loss
thereof is not adverse in any material respect to Obligor.

Section 4.03. Stay, Extension and Usury Laws.

      Obligor covenants (to the extent that it may lawfully do so) that it shall
not at any time insist upon, plead, or in any manner whatsoever claim or take
the benefit or advantage of, any stay, extension or usury law wherever enacted,
now or at any time hereafter in force, that may affect the covenants or the
performance of this Mirror Note; and Obligor (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law.

                              DEFAULTS AND REMEDIES

Section 5.01. Events of Default.

      A "Mirror Event of Default " shall have occurred if:

                                     - 6 -
<PAGE>

            (a) Obligor defaults in the payment when due of interest (including
any Mirror Liquidated Damages or Mirror Deferred Interest), on this Mirror Note
and such default continues for a period of 30 days; provided that a failure to
make any of the first six scheduled interest payments on the Original Principal
Amount of this Mirror Note when due on the applicable Mirror Interest Payment
Date will constitute a Mirror Event of Default with no grace or cure period if
and to the extent that a failure by CCI to make its corresponding interest
payment on the applicable CCI Interest Payment Date has resulted in a CCI Event
of Default with no grace or cure period;

            (b) Obligor defaults in payment when due of the principal of or
premium, if any, on the Notes; or

            (c) A CCI Event of Default has occurred.

Section 5.02. Acceleration.

      Upon the acceleration of any amounts payable by Holder pursuant to Section
6.02 of the Indenture, the same Mirror Accreted Principal Amount of this Mirror
Note, together with any accrued and unpaid interest (including any Mirror
Liquidated Damages or Mirror Deferred Interest) thereon, shall immediately and
automatically become due and payable by Obligor to Holder.

      Holder by written notice to Obligor may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing CCI Events of Default under the Indenture (except nonpayment
of principal, interest or premium that has become due solely because of the
acceleration) have been cured or waived; provided that such rescission shall be
automatic if such acceleration has been rescinded pursuant to the terms of the
Indenture.

Section 5.03. Other Remedies.

      If a Mirror Event of Default occurs and is continuing, Holder may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest on this Mirror Note or to enforce the performance of any provision of
this Mirror Note.

      A delay or omission by Holder in exercising any right or remedy accruing
upon a Mirror Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Mirror Event of Default. All
remedies are cumulative to the extent permitted by law.

Section 5.04. Waiver of Existing Mirror Defaults.

      Holder by the adoption of a resolution of Holder's board of directors may
waive an existing Mirror Default or Mirror Event of Default and its consequences
hereunder, except a continuing Mirror Default or Mirror Event of Default in the
payment of the principal of, premium, if any, or interest (including any Mirror
Liquidated Damages or Mirror Deferred Interest) on, this Mirror Note (including
in connection with an offer to purchase); provided, that such waiver shall be
automatic in the case of any Mirror Event of Default predicated solely on a CCI
Event of Default, to the extent that the underlying CCI Event of Default has

                                     - 7 -
<PAGE>

been cured or waived in accordance with the Indenture. Upon any such waiver
whether by resolution or automatically, such Mirror Default shall cease to
exist, and any Mirror Event of Default arising therefrom shall be deemed to have
been cured for every purpose of this Mirror Note; but no such waiver shall
extend to any subsequent or other Mirror Default or impair any right consequent
thereon.

                                   ARTICLE 6

                            CONVERSION OF MIRROR NOTE

Section 6.01. Conversion and Conversion Rate.

      Subject to and upon compliance with the provisions of this Article 6, upon
conversion of any CCI Accreted Principal Amount of the CCI Notes into shares of
Common Stock pursuant to the terms of the Indenture, a portion of this Mirror
Note in a Mirror Accreted Principal Amount equal to the CCI Mirror Accreted
Principal Amount of the CCI Notes so converted shall convert automatically into
fully paid and nonassessable (calculated as to each conversion to the nearest
1/100th of a Membership Unit) Membership Units of Obligor at the Mirror
Conversion Rate, determined as hereinafter provided, in effect at the time of
conversion), plus amounts equal to the Early Conversion Make Whole Amount and
Redemption Make Whole Amount if required to be paid by CCI to the converting
holders of the CCI Notes pursuant to the terms of the Indenture and to the
extent paid by CCI to such holders in Common Stock.

      The rate at which Membership Units shall be delivered upon conversion
(herein called the "Mirror Conversion Rate") shall be initially 413.2231
Membership Units for each U.S. $1,000 principal amount of this Mirror Note. The
Mirror Conversion Rate shall be adjusted in certain instances as provided in
this Article 6.

Section 6.02. Conversion.

      If this Mirror Note, or a portion thereof, is converted during the Record
Date Period, Holder shall pay Obligor (except with respect to any portion
thereof which has been called for redemption on a occurring within such Record
Date Period and, as a result, the right to convert would terminate in such
period) a payment in New York Clearing House funds or other funds acceptable to
Obligor of an amount equal to the interest payable on the related Mirror
Interest Payment Date on the principal amount of this Mirror Note being
surrendered for conversion, provided that if this Mirror Note or any portion
thereof has been called for redemption on a Mirror Repurchase Date occurring
during a Record Date Period, and is converted during such period, Holder will be
entitled to receive the interest accruing on this Mirror Note or the portion
thereof from the Mirror Interest Payment Date next preceding the date of such
conversion to such succeeding Mirror Interest Payment Date and Holder shall not
be required to pay such interest upon such conversion. The interest payable on
an Mirror Interest Payment Date when this Mirror Note (or portion thereof, if
applicable) is converted during the Record Date Period shall be paid to Holder
as of such Regular Record Date in an amount equal to the interest that would
have been payable on the portion of this Mirror Note so converted if such amount
had been converted as of the close of business on such Mirror Interest Payment
Date. Except as provided in this paragraph, no cash payment

                                     - 8 -
<PAGE>

or adjustment shall be made upon any conversion on account of any interest
accrued from the Mirror Interest Payment Date next preceding the conversion
date, in respect of any portion of this Mirror Note converted, or on account of
any dividends on the Membership Units issued upon conversion. Obligor's delivery
to Holder of the number of Membership Units (and cash in lieu of fractions
thereof, as provided in this Mirror Note) into which any portion of this Mirror
Note is convertible will be deemed to satisfy Obligor's obligation to pay such
portion of the principal amount of this Mirror Note.

      The portion of the Mirror Accreted Principal Amount of this Mirror Note
converted pursuant to this Article 6 shall be deemed to have been converted
immediately prior to the close of business on the day of surrender of the CCI
Notes that triggered the conversion of such portion of this Mirror Note in
accordance with the foregoing provisions. At such time, the rights of Holder
with respect to that portion of this Mirror Note that converted into Membership
Units shall cease and Holder shall be treated for all purposes as the record
holder or holders of such Membership Units at such time.

      This Mirror Note may be converted in part, but only if the principal
amount to be converted is any integral multiple of U.S. $1,000 and the principal
amount of this Mirror Note to remain outstanding after such conversion is equal
to U.S. $1,000 or any integral multiple of $1,000 in excess thereof.

Section 6.03. Fractions of Membership Units.

      No fractional Membership Units shall be issued upon conversion of all or a
portion of this Mirror Note. Instead of any fractional Membership Unit which
would otherwise be issuable upon conversion of all or any portion of this Mirror
Note, Obligor shall calculate and pay a cash adjustment in respect of such
fraction (calculated to the nearest 1/100th of a Membership Unit) in an amount
equal to the same fraction of the Sale Price on the day of conversion (or round
up the number of Membership Units issuable upon conversion of any portion of
this Mirror Note to the nearest whole Membership Unit).

Section 6.04. Adjustment of Conversion Rate.

      (a) The Mirror Conversion Rate shall be automatically adjusted upon each
adjustment of the Conversion Rate under the Indenture, by applying the
applicable formula for adjustment of the Conversion Rate to the Mirror
Conversion Rate, so as to adjust the Mirror Conversion Rate by a number of
Membership Units equal to the number of shares of Common Stock by which the
Conversion Rate is adjusted under the Indenture.

      (b) Notwithstanding any other provision of this Section 6, if (i) any of
Clause (b) of Article Third and Clauses (a)(ii) and (b)(iii) of Article Fourth
of CCI's Restated Certificate of Incorporation as in effect on the date hereof
or Sections 3.5.4, 3.6.1, 3.6.4(b), 3.6.4(c), and 5.1.7 of the Amended and
Restated Limited Liability Company Agreement of Obligor as in effect on the date
hereof has been amended so as to substantively modify the provisions thereof, or
(ii) CCI or Obligor is not in substantial compliance with the provisions
described in clause (i) (each of the events described in clauses (i) and (ii)
above, a "One-for-One Event"), the Mirror Conversion Rate shall not be adjusted
pursuant to the Indenture and instead shall be adjusted upon the occurrence of
certain events affecting Holder's economic

                                     - 9 -
<PAGE>

interest in Obligor receivable upon conversion of the Mirror Note, including but
not limited to subdivisions or combinations of, or distributions of securities
on the Membership Units, to the extent necessary to reflect the economic
interest Holder would have had in Obligor if this Mirror Note had been converted
prior to the occurrence of a One-for-One Event. In the event a One-for-One Event
occurs, the Mirror Conversion Rate shall be reasonably adjusted such that upon
conversion of this Mirror Note, or a portion hereof, Holder shall be entitled to
receive the kind and amount of securities (or any successor securities) that
Holder would have owned if it had converted this Mirror Note, or such portion
hereof, immediately prior to the One-for-One Event and had retained the
securities received in such hypothetical conversion until after the event or
events requiring any adjustment to the Mirror Conversion Rate.

Section 6.05. Obligor to Reserve Membership Units.

      Obligor shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Membership Units, for the
purpose of effecting the conversion of all or any portion of the principal
amount outstanding under this Mirror Note, the full number of Membership Units
issuable upon the conversion of the entire principal amount outstanding from
time to time under this Mirror Note.

Section 6.06. Taxes on Conversions.

      Obligor will pay any and all taxes and duties that may be payable in
respect of the issue or delivery of Membership Units on conversion of all or any
portion of this Mirror Note pursuant hereto.

Section 6.07. Representation Regarding Membership Units.

      Obligor represents that all Membership Units which may be delivered upon
conversion of all or any portion of this Mirror Note, upon such delivery, will
have been duly authorized and validly issued and will be fully paid and
nonassessable.

Article 11 of the Indenture, Obligor shall repurchase a portion of the Mirror
Accreted Principal Amount of this Mirror Note equal to 100% of the aggregate CCI
Accreted Principal Amount of the CCI Notes so repurchased, plus interest
(including any Mirror Liquidated Damages or Mirror Deferred Interest) accrued on
this Mirror Note to but excluding the Mirror Repurchase Date and any Change of
Control (the "Mirror Repurchase Price"); provided, however, that installments of
interest on the portion of this Mirror Note whose Stated Maturity is on or prior
to the Repurchase Date shall be payable to CCI according to the terms of this
Mirror Note. If the repurchase price of the CCI Notes is paid in shares of
Common Stock pursuant to Section 11.01 of the Indenture, then the Mirror
Repurchase Price shall be paid by the delivery of that number of Membership
Units to CCI equal to the

                                     - 10 -

number of shares of Common Stock issued by Holder to repurchase the CCI Notes;
provided that in the event a One-for-One Event occurs, Obligor will issue the
number of Membership Units with a fair market value equal to the number of
shares of Common Stock issued to repurchase the CCI Notes. Whenever there is a
reference, in any context, to the principal of this Mirror Note as of any time,
such reference shall be deemed to include reference to the Mirror Repurchase
Price payable in respect of amounts outstanding under this Mirror Note to the
extent that such Mirror Repurchase Price is, was or would be so payable at such
time, and express mention of the Repurchase Price in any provision of this
Mirror Note shall not be construed as excluding the Mirror Repurchase Price in
those provisions of this Mirror Note when such express mention is not made.

Section 7.02. Optional Repurchase.

      (a) In the event that Holder has elected to exercise the option to redeem
all or any portion of the CCI Notes by Holder pursuant to Section 3.07 of the
Indenture, Obligor shall, one Business Day prior to or on the date of such
repurchase, repurchase a portion of this Mirror Note equal to 100% of the
aggregate CCI Accreted Principal Amount of the CCI Notes being so redeemed plus
interest (including any Mirror Deferred Interest or Mirror Liquidated Damages)
accrued on this Mirror Note to but excluding the applicable Mirror Repurchase
Date. In addition, in the event that Holder is required to pay any Early
Conversion Make Whole Amount or Redemption Make Whole Amount, Obligor shall pay
to Holders on such Mirror Repurchase Date amounts equal to such Early Conversion
Make Whole Amount and/or Redemption Make Whole Amount in respect of this Mirror
Note.

      (b) If and to the extent that Holder pays all or any portion of the CCI
Redemption Price (including any Early Conversion Make Whole Amount or Redemption
Make Whole Amount payable in respect thereof) to the holders of CCI Notes in
shares of Common Stock in lieu of cash, Obligor shall likewise pay all or, as
the case may be, an equal portion of the Mirror Repurchase Price to Holder in
Membership Units, in a number equal to the number of shares of Common Stock so
paid by Holder to holders of the CCI Notes, in lieu of all or the applicable
portion of the cash payment otherwise payable on such Mirror Repurchase Date in
respect of this Mirror Note, as described in paragraph (a) of this Section 7.02.

Section 7.03. Mechanics of Repurchase.

      (1) On each Mirror Repurchase Date, Obligor shall pay or cause to be paid
to Holder the Mirror Repruchase Price of the portion of this Mirror Note to be
repurchased in cash, or, if Membership Units are to be paid as provided above,
as promptly after the Repurchase Date as practicable; provided, however, that
installments of interest that mature on or prior to the Repurchase Date shall be
payable in cash to Holder.

      (2) If any portion of this Mirror Note to be repurchased pursuant to this
Article 7 shall not be paid on the Repurchase Date, such principal amount shall,
until paid, bear interest to the extent permitted by applicable law from the
Repurchase Date at the rate specified in Section 2.02 hereof and such unpaid
portion shall remain convertible into Membership Units until such portion shall
have been paid or duly provided for.

      (3) Any issuance of Membership Units in respect of the Mirror Repurchase
Price shall be deemed to have been effected immediately prior to the close of
business on the Repurchase Date and Holder shall be deemed to have become on the
Repurchase Date the holder of record of such Membership Units.

      (4) No fractions of Membership Units shall be issued upon repurchase of
amounts outstanding under this Mirror Note. Instead of any fractional share of
Membership Units which would otherwise be issuable on the repurchase of any
portion of this Mirror Note, Obligor shall deliver to Holder a check for the
amount determined by multiplying the current market price of a full share of
Common Stock by the fraction, and rounding the result to the nearest cent or
round up the number of Membership Units to be issued to the nearest Membership
Unit; provided that in the event of a One-for-One Event occurs, Obligor shall
deliver to Holder a check for the amount determined by multiplying the fair
market value of a Membership Unit by the fraction and rounding the result to the
nearest whole cent. For purposes of this Section 7, the current market price of
a share of Common Stock is the Closing Price Per Share of the Common Stock on
the Trading Day immediately preceding the Repurchase Date.

      The provisions of this Article 7 above that require the Obligor to
repurchase all or a portion of this Mirror Note shall be applicable regardless
of whether or not any other provisions in this Mirror Note are applicable.
