unconditionally and irrevocably, guarantees to the Collateral Trustee, for the
benefit of the Secured Parties and their respective successors, indorsees,
transferees and assigns, the prompt and complete payment and performance by the
Company when due (whether at the stated maturity, by acceleration or otherwise)
of the Secured Obligations.

         (b)      Anything herein or in any other Secured Debt Document to the
contrary notwithstanding, (i) the recourse of the Collateral Trustee or the
Secured Parties against each Guarantor hereunder and under the other Secured
Debt Documents shall be limited solely to such Guarantor's ownership interests
in CCEC pledged to the Collateral Trustee, for the benefit of the Secured
Parties, pursuant to the Guarantor Pledge Agreement and (ii) the maximum
liability of each Guarantor hereunder and under the other Secured Debt Documents
shall in no event exceed the amount which can be guaranteed by such Guarantor
under applicable federal and state laws relating to the insolvency of debtors
(after giving effect to the right of contribution established in Section 2.2).

         (c)      Each Guarantor agrees that the Secured Obligations may at any
time and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guarantee contained in this Section 2 or
affecting the rights and remedies of the Collateral Trustee or any Secured Party
hereunder.

         (d)      The guarantee contained in this Section 2 shall remain in full
force and effect until all the Secured Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2



                                                                               5

shall have been satisfied by payment in full and all commitments to extend
credit under all Credit Facilities the Indebtedness under which constitutes
Priority Lien Debt shall have been terminated or expired.

         (e)      No payment made by the Company, any of the Guarantors, any
other guarantor or any other Person or received or collected by the Collateral
Trustee or any Secured Party from the Company, any of the Guarantors, any other
guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Secured Obligations shall be deemed to modify,
reduce, release or otherwise affect the liability of any Guarantor hereunder
which shall, notwithstanding any such payment (other than any payment made by
such Guarantor in respect of the Secured Obligations or any payment received or
collected from such Guarantor in respect of the Secured Obligations), remain
liable for the Secured Obligations up to the maximum liability of such Guarantor
hereunder until the Secured Obligations are paid in full and all commitments to
extend credit under all Credit Facilities the Indebtedness under which
constitutes Priority Lien Debt shall have been terminated or expired.

         2.2      Right of Contribution. Each Guarantor hereby agrees that to
the extent that a Guarantor shall have paid more than its proportionate share of
any payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder which has not paid
its proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 2.3. The provisions of
this Section 2.2 shall in no respect limit the obligations and liabilities of
any Guarantor to the Collateral Trustee and the Secured Parties, and each
Guarantor shall remain liable to the Collateral Trustee and the Secured Parties
for the full amount guaranteed by such Guarantor hereunder.

         2.3      No Subrogation. Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the Collateral Trustee or any Secured Party, no Guarantor shall be entitled to
be subrogated to any of the rights of the Collateral Trustee or any Secured
Party against the Company or any other Guarantor or any collateral security or
guarantee or right of offset held by the Collateral Trustee or any Secured Party
for the payment of the Secured Obligations, nor shall any Guarantor seek or be
entitled to seek any contribution or reimbursement from the Company or any other
Guarantor in respect of payments made by such Guarantor hereunder, until all
amounts owing to the Collateral Trustee and the Secured Parties by the Company
on account of the Secured Obligations are paid in full and all commitments to
extend credit under all Credit Facilities the Indebtedness under which
constitutes Priority Lien Debt shall have been terminated or expired. If any
amount shall be paid to any Guarantor on account of such subrogation rights at
any time when all of the Secured Obligations shall not have been paid in full,
such amount shall be held by such Guarantor in trust for the Collateral Trustee
and the Secured Parties, segregated from other funds of such Guarantor, and
shall, forthwith upon receipt by such Guarantor, be turned over to the
Collateral Trustee in the exact form received by such Guarantor (duly indorsed
by such Guarantor to the Collateral Trustee, if required), to be applied against
the Secured Obligations, whether matured or unmatured, in such order as the
Collateral Trustee may determine, subject to the terms and provisions of the
Collateral Trust Agreement.

         2.4      Amendments, etc. with respect to the Secured Obligations. Each
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Secured
Obligations made by the Collateral Trustee or any Secured Party may be rescinded
by the Collateral Trustee or such Secured Party and any of the Secured
Obligations continued, and the Secured Obligations, or the liability of any
other Person upon or for any part thereof, or any collateral security or
guarantee therefor or right of offset with respect thereto, may, from time to
time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by



                                                                               6

the Collateral Trustee or any Secured Party, and any of the Secured Debt
Documents may be amended, modified, supplemented or terminated, in whole or in
part, as the requisite parties thereto deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the
Collateral Trustee or any Secured Party for the payment of the Secured
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Collateral Trustee nor any Secured Party shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Secured Obligations or for the guarantee contained in this Section 2 or any
property subject thereto.

         2.5      Guarantee Absolute and Unconditional. Each Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Secured Obligations and notice of or proof of reliance by the Collateral Trustee
or any Secured Party upon the guarantee contained in this Section 2 or
acceptance of the guarantee contained in this Section 2; the Secured
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred, or renewed, extended, amended or waived, in reliance
upon the guarantee contained in this Section 2; and all dealings between the
Company and any of the Guarantors, on the one hand, and the Collateral Trustee
and the Secured Parties, on the other hand, likewise shall be conclusively
presumed to have been had or consummated in reliance upon the guarantee
contained in this Section 2. Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the
Company or any of the Guarantors with respect to the Secured Obligations. Each
Guarantor understands and agrees that the guarantee contained in this Section 2
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to (a) the validity or enforceability of any of the
Secured Debt Documents, any of the Secured Obligations or any other collateral
security therefor or guarantee or right of offset with respect thereto at any
time or from time to time held by the Collateral Trustee or any Secured Party,
(b) any defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by the Company
or any other Person against the Collateral Trustee or any Secured Party, or (c)
any other circumstance whatsoever (with or without notice to or knowledge of the
Company or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Company for the Secured
Obligations, or of such Guarantor under the guarantee contained in this Section
2, in bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, the
Collateral Trustee or any Secured Party may, but shall be under no obligation
to, make a similar demand on or otherwise pursue such rights and remedies as it
may have against the Company, any other Guarantor or any other Person or against
any collateral security or guarantee for the Secured Obligations or any right of
offset with respect thereto, and any failure by the Collateral Trustee or any
Secured Party to make any such demand, to pursue such other rights or remedies
or to collect any payments from the Company, any other Guarantor or any other
Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of the Company, any other
Guarantor or any other Person or any such collateral security, guarantee or
right of offset, shall not relieve any Guarantor of any obligation or liability
hereunder, and shall not impair or affect the rights and remedies, whether
express, implied or available as a matter of law, of the Collateral Trustee or
any Secured Party against any Guarantor. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

         2.6      Reinstatement. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Secured Obligations is rescinded or
must otherwise be restored or returned by the Collateral Trustee or any Secured
Party upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Company or any Guarantor, or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Company or any Guarantor or any substantial part of its
property, or otherwise, all as though such payments had not been made.



                                                                               7

         2.7      Payments. Each Guarantor hereby guarantees that payments
hereunder will be paid to the Collateral Trustee without set-off or counterclaim
in Dollars at an office of the Collateral Trustee in the City of New York.

                           SECTION 3 GRANT OF SECURITY INTEREST

                  The Company hereby (i) assigns and transfers to the Collateral
Trustee, and hereby grants to the Collateral Trustee, for the benefit of the
Secured Priority Lien Parties, a first priority security interest in, all of the
following property now owned or at any time hereafter acquired by the Company or
in which the Company now has or at any time in the future may acquire any right,
title or interest, except the Excluded Assets (collectively, the "Collateral"),
as collateral security for the prompt and complete payment and performance when
due (whether at the stated maturity, by acceleration or otherwise) of the
Priority Lien Obligations and (ii) assigns and transfers to the Collateral
Trustee, and hereby grants to the Collateral Trustee, for the benefit of the
Secured Parity Lien Parties, a second priority security interest in, all of the
Collateral, as collateral security for the prompt and complete payment and
performance when due (whether at the stated maturity, by acceleration or
otherwise) of the Parity Lien Obligations:

         (a)      all Accounts;

         (b)      all Chattel Paper;

         (c)      all Contracts;

         (d)      all Deposit Accounts;

         (e)      all Documents;

         (f)      all Equipment;

         (g)      all General Intangibles;

         (h)      all Instruments;

         (i)      all Intellectual Property;

         (j)      all Inventory;

         (k)      all Investment Property;

         (l)      all Letter-of-Credit Rights;

         (m)      all other property not otherwise described above;

         (n)      all books and records pertaining to the Collateral; and

         (o)      to the extent not otherwise included, all Proceeds, Supporting
Obligations and products of any and all of the foregoing and all collateral
security and guarantees given by any Person with respect to any of the
foregoing;



                                                                               8

                  provided, however, that notwithstanding any of the other
provisions set forth in this Section 3, this Agreement shall not, at any time,
constitute a grant of a security interest in any property that is, at such time,
an Excluded Asset.

                  In addition, notwithstanding any other provision set forth in
this Agreement, to the extent that any other Security Document to which the
Collateral Trustee is a party grants a security interest in any of the
Collateral and a security interest in such Collateral is also granted in this
Agreement and the provisions of such other Security Document are inconsistent
with the provisions of this Agreement with respect to such Collateral, the
provisions of such other Security Document shall control.

                  This Agreement and the security interests and Liens granted
and created herein secures the payment an performance of all Secured Obligations
of the Company now or hereafter, whether direct or indirect, absolute or
contingent, and whether for principal, reimbursement obligations, interest
(including any interest accruing at the then applicable rate provided in any
applicable Secured Debt Document after the maturity of the Indebtedness
thereunder and reimbursement obligations therein and interest accruing at the
then applicable rate provided in any applicable Secured Debt Document after the
filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Company, whether or not a
claim for post-filing or post-petition interest is allowed in such proceeding),
fees, premiums, penalties, indemnifications, expenses or otherwise, and
including all amounts that constitute part of the Secured Obligations and would
be owed by the Company but for the fact that they are unenforceable or not
allowed due to a pending Bankruptcy Case or Insolvency Proceeding. Without
limiting the generality of the foregoing, it is the intent of the parties that
(i) the Liens securing the Parity Lien Obligations are subject and subordinate
to the Liens securing the Priority Lien Obligations up to the Priority Lien Cap
and (ii) this Agreement creates two separate and distinct Liens: the first Lien
securing the payment and performance of the Priority Lien Obligations and the
second Lien securing the payment and performance of the Parity Lien Obligations.

                    SECTION 4 REPRESENTATIONS AND WARRANTIES

                  The Company hereby represents and warrants to the Collateral
Trustee and each Secured Party that:

         4.1      Title; No Other Liens. Except for the security interest
granted to the Collateral Trustee for the benefit of the Secured Parties
pursuant to this Agreement and the other Liens permitted to exist on the
Collateral by the Secured Debt Documents, the Company owns each item of the
Collateral free and clear of any and all Liens or claims of others. No financing
statement or other public notice with respect to all or any part of the
Collateral is on file or of record in any public office, except such as have
been filed in favor of the Collateral Trustee, for the benefit of the Secured
Parties, pursuant to this Agreement or as are permitted by each of the Secured
Debt Documents. For the avoidance of doubt, it is understood and agreed that the
Company may, as part of its business, grant licenses to third parties to use
Intellectual Property owned or developed by the Company. For purposes of this
Agreement and the other Secured Debt Documents, such licensing activity shall
not constitute a "Lien" on such Intellectual Property. Each of the Collateral
Trustee and each Secured Party understands that any such licenses may be
exclusive to the applicable licensees, and such exclusivity provisions may limit
the ability of the Collateral Trustee to utilize, sell, lease or transfer the
related Intellectual Property or otherwise realize value from such Intellectual
Property pursuant hereto.

         4.2      Perfected First Priority Liens. The security interests granted
pursuant to this Agreement (a) upon completion of the filings and other actions
specified on Schedule 2 (which, in the case of all filings and other documents
referred to on said Schedule, have been delivered to the Collateral Trustee in
completed and duly executed form) will constitute valid perfected security
interests in all of the Collateral



                                                                               9

in favor of the Collateral Trustee, for the benefit of the Secured Parties, as
collateral security for the Secured Obligations, enforceable in accordance with
the terms hereof against all creditors of the Company and any Persons purporting
to purchase any Collateral from the Company and (b) are prior to all other Liens
on the Collateral in existence on the date hereof except for unrecorded Liens
permitted by the Secured Debt Documents which have priority over the Liens on
the Collateral by operation of law.

         4.3      Jurisdiction of Organization; Chief Executive Office. On the
date hereof, the Company's jurisdiction of organization, identification number
from the jurisdiction of organization (if any), and the location of the
Company's chief executive office or sole place of business or principal
residence, as the case may be, are specified on Schedule 3. The Company has
furnished to the Collateral Agent a certified charter, certificate of
incorporation or other organization document and long-form good standing
certificate as of a date which is recent to the date hereof.

         4.4      Inventory and Equipment. On the date hereof, (a) the Inventory
and the Equipment (other than mobile goods) representing natural gas and oil
assets (including any related extraction, processing or similar equipment, but
excluding natural gas power plants), in each case with a fair market value of
$1,000,000 or more, are kept at the locations listed on Schedule 4A and (b) the
Inventory and the Equipment (other than mobile goods and that Inventory and
Equipment described in clause (a) above), in each case with a fair market value
of $1,000,000 or more, are kept at the locations listed on Schedule 4B.

         4.5      Farm Products. None of the Collateral constitutes, or is the
Proceeds of, Farm Products.

         4.6      [Intentionally Omitted]

         4.7      Receivables. (a) No amount payable to the Company under or in
connection with any Receivable is evidenced by any Instrument or Chattel Paper
which has not been delivered to the Collateral Trustee (other than the Panda
Note).

         (b)      None of the obligors on any Receivables is a Governmental
Authority.

         4.8      Intellectual Property. Schedule 5 lists all material
Intellectual Property owned by the Company in its own name on the date hereof.

                              SECTION 5 COVENANTS

                  The Company covenants and agrees with the Collateral Trustee
and the Secured Parties that, from and after the date of this Agreement until
the Secured Obligations shall have been paid in full and all commitments to
extend credit under all Credit Facilities the Indebtedness under which
constitutes Priority Lien Debt shall have been terminated or expired:

         5.1      Delivery of Instruments, Certificated Securities and Chattel
Paper. If any amount payable under or in connection with any of the Collateral
shall be or become evidenced by any Instrument, Certificated Security or Chattel
Paper, such Instrument, Certificated Security or Chattel Paper shall be
immediately delivered to the Collateral Trustee, duly indorsed in a manner
satisfactory to the Collateral Trustee, to be held as Collateral pursuant to
this Agreement. The Company agrees to promptly (and in any event within 15 days
from the date hereof) deliver the Panda Note to the Collateral Trustee, duly

Collateral pursuant to this Agreement.

         5.2      Maintenance of Insurance. (a) The Company will, and will cause
each of its Subsidiaries to, maintain or cause to be maintained, with
financially sound and reputable companies, insurance



                                                                              10

policies insuring the Inventory and Equipment and other properties and business
(including business interruption insurance) of the Company and its Subsidiaries
against loss by fire, explosion, theft and such other casualties and
contingencies and of such types and in such amounts as is customary in the case
of similar businesses.

         (b)      As promptly as practicable after each year following the date
of this Agreement and beginning with 2004, and in any event prior to February 1
in each such year, the Company will furnish to the Collateral Trustee and each
Secured Debt Representative an Officers' Certificate setting forth the nature
and extent of all insurance maintained by the Company and its Subsidiaries.

         5.3      Maintenance of Perfected Security Interest; Further
Documentation. (a) The Company shall maintain the security interest created by
this Agreement as a perfected security interest having at least the priority
described in Section 4.2 and shall defend such security interest against the
claims and demands of all Persons whomsoever, subject to the rights of the
Company under the Secured Debt Documents to dispose of the Collateral and the
Lien release provisions in the Secured Debt Documents.

         (b)      The Company will promptly and duly execute and deliver, and
have recorded, such further instruments and documents and take such further
actions as necessary for the purpose of obtaining or preserving the full
benefits of this Agreement and of the rights and powers herein granted,
including, without limitation, (i) filing any financing or continuation
statements under the Uniform Commercial Code (or other similar laws) in effect
in any jurisdiction with respect to the security interests created hereby and
(ii) in the case of Investment Property, Deposit Accounts, Letter-of-Credit
Rights and any other relevant Collateral, taking any actions necessary to enable
the Collateral Trustee to obtain "control" (within the meaning of the applicable
Uniform Commercial Code) with respect thereto.

         5.4      Changes in Locations, Name, etc. The Company will not, except
upon 15 days' prior written notice to the Collateral Trustee and each Secured
Debt Representative and delivery to the Collateral Trustee of (a) all additional
executed financing statements and other documents as necessary to maintain the
validity, perfection and priority of the security interests provided for herein
and (b) if applicable, a written supplement to Schedule 4 showing any additional
location at which Inventory or Equipment shall be kept:

         (i)      change its jurisdiction of organization or the location of its
chief executive office or sole place of business or principal residence from
that referred to in Section 4.3; or

         (ii)     change its name.

         5.5      [Intentionally Omitted]

                         SECTION 6. REMEDIAL PROVISIONS

         6.1      Proceeds to be Turned Over To Collateral Trustee. If an
Actionable Default shall occur and be continuing, all Proceeds received by the
Company consisting of cash, checks and other near-cash items shall be held by
the Company in trust for the Collateral Trustee and the Secured Parties,
segregated from other funds of the Company, and shall, forthwith upon receipt by
the Company, be turned over to the Collateral Trustee in the exact form received
by the Company (duly indorsed in blank by the Company or to the Collateral
Trustee, if required). All Proceeds of Collateral received by the Collateral
Trustee hereunder shall be held by the Collateral Trustee in a Collateral
Account maintained under its sole dominion and control or under the sole
dominion and control of the Credit Agreement Agent, acting as agent for the
Collateral Trustee. All Proceeds while held by the Collateral Trustee in a
Collateral Account (or by the Company in trust for the Collateral Trustee and
the Secured Parties) shall continue to be held as



                                                                              11

collateral security for all the Secured Obligations and shall not constitute
payment thereof until applied as provided in Section 6.2.

         6.2      Application of Proceeds. If an Actionable Default shall have
occurred and be continuing, the Collateral Trustee may apply all or any part of
Proceeds constituting Collateral, whether or not held in any Collateral Account,
in payment of the Secured Obligations, in each case subject to the terms and
provisions of the Collateral Trust Agreement.

         6.3      Code and Other Remedies. If an Actionable Default shall occur
and be continuing, the Collateral Trustee, on behalf of the Secured Parties, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Secured Obligations, all rights and remedies of a secured party
under the New York UCC or any other applicable law, in each case subject to the
terms and provisions of the Collateral Trust Agreement. Without limiting the
generality of the foregoing, and in each case subject to the terms and
provisions of the Collateral Trust Agreement, the Collateral Trustee, without
demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or
upon the Company or any other Person (all and each of which demands, defenses,
advertisements and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, lease, assign, give option or options
to purchase, or otherwise dispose of and deliver the Collateral or any part
thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
the Collateral Trustee or any Secured Party or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk.
The Collateral Trustee or any Secured Party shall have the right, but shall not
be obligated to, upon any such public sale or sales, and, to the extent
permitted by law, upon any such private sale or sales, to purchase the whole or
any part of the Collateral so sold, free of any right or equity of redemption in
the Company, which right or equity is hereby waived and released. The Company
further agrees, at the Collateral Trustee's request, to assemble the Collateral
and make it available to the Collateral Trustee at places which the Collateral
Trustee shall reasonably select, whether at the Company's premises or elsewhere.
The Collateral Trustee shall apply the net proceeds of any action taken by it
pursuant to this Section 6.3 in accordance with the provisions of the Collateral
Trust Agreement. To the extent permitted by applicable law, the Company waives
all claims, damages and demands it may acquire against the Collateral Trustee or
any Secured Party arising out of the exercise by them of any rights hereunder.
If any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition.

         6.4      Deficiency. The Company shall remain liable for any deficiency
if the proceeds of any sale or other disposition of the Collateral are
insufficient to pay its Secured Obligations and the fees and disbursements of
any attorneys employed by the Collateral Trustee to collect such deficiency.

                       SECTION 7. THE COLLATERAL TRUSTEE

         7.1      Duty of Collateral Trustee. The Collateral Trustee's sole duty
with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the New York UCC or
otherwise, shall be to deal with it in the same manner as the Collateral Trustee
deals with similar property for its own account. Neither the Collateral Trustee,
any Secured Party nor any of their respective officers, directors, employees or
agents shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of the Company or any
other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof. The powers conferred on the



                                                                              12

Collateral Trustee and the Secured Parties hereunder are solely to protect the
Collateral Trustee's and the Secured Parties' interests in the Collateral and
shall not impose any duties or obligations upon the Collateral Trustee or any
Secured Party to exercise any such powers. The Collateral Trustee and the
Secured Parties shall be accountable only for amounts that they actually receive
as a result of the exercise of such powers, and neither they nor any of their
officers, directors, employees or agents shall be responsible to the Company for
any act or failure to act hereunder, except for their own gross negligence or
willful misconduct.

                  Notwithstanding anything to the contrary contained in this
Agreement, the rights, privileges, powers, benefits and immunities of the
Collateral Trustee hereunder are subject to the terms, conditions and
limitations set forth in the Collateral Trust Agreement, reference to which is
made for all purposes; provided, however, that any forbearance by the Collateral
Trustee in exercising any right or remedy available to it under the Collateral
Trust Agreement shall not give rise to a defense on the part of the Grantors
with respect to the Collateral Trustee's exercise of any right or remedy
pursuant to this Agreement or as otherwise afforded by applicable law.

         7.2      Execution of Financing Statements. Pursuant to any applicable
law, the Company authorizes the Collateral Trustee to file or record financing
statements and other filing or recording documents or instruments with respect
to the Collateral without the signature of the Company in such form and in such
offices as are necessary to perfect the security interests of the Collateral
Trustee under this Agreement. The Company authorizes the Collateral Trustee to
use the collateral description "all personal property except for Excluded
Assets" in any such financing statements. The Company hereby ratifies and
authorizes the filing by the Collateral Trustee of any financing statement with
respect to the Collateral made prior to the date hereof. The Collateral Trustee
shall be under no obligation to file or record such financings statements or to
make any other filing under the UCC in connection with this Agreement.

         7.3      Authority of Collateral Trustee. The Company acknowledges that
the rights and responsibilities of the Collateral Trustee under this Agreement
with respect to any action taken by the Collateral Trustee or the exercise or
non-exercise by the Collateral Trustee of any option, voting right, request,
judgment or other right or remedy provided for herein or resulting or arising
out of this Agreement shall, as between the Collateral Trustee and the Secured
Parties, be governed by the Collateral Trust Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Collateral Trustee and the Company, the Collateral Trustee shall
be conclusively presumed to be acting on behalf of the Secured Parties with full
and valid authority so to act or refrain from acting, and the Company shall not
be under any obligation, or entitlement, to make any inquiry respecting such
authority.

                            SECTION 8. MISCELLANEOUS

         8.1      Amendments in Writing. None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except in
accordance with Section 7.1 of the Collateral Trust Agreement.

         8.2      Notices. All notices, requests and demands to or upon the
Collateral Trustee, any Secured Debt Representative or the Company hereunder
shall be effected in the manner provided for in Section 7.5 of the Collateral
Trust Agreement; provided that any such notice, request or demand to or upon any
Guarantor shall be addressed to such Guarantor at its notice address set forth
on Schedule 1.

         8.3      No Waiver by Course of Conduct; Cumulative Remedies. Neither
the Collateral Trustee nor any Secured Party shall by any act (except by a
written instrument pursuant to Section 8.1), delay,



                                                                              13

indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Actionable Default. No failure to
exercise, nor any delay in exercising, on the part of the Collateral Trustee or
any Secured Party, any right, power or privilege hereunder shall operate as a
waiver thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Collateral Trustee or
any Secured Party of any right or remedy hereunder on any one occasion shall not
be construed as a bar to any right or remedy which the Collateral Trustee or
such Secured Party would otherwise have on any future occasion. The rights and
remedies herein provided are cumulative, may be exercised singly or concurrently
and are not exclusive of any other rights or remedies provided by law.

         8.4      Enforcement Expenses; Indemnification. (a) The Guarantors
jointly and severally agree to pay or reimburse the Collateral Trustee for all
its costs and expenses incurred in collecting against such Guarantor under the
guarantee contained in Section 2 or otherwise enforcing or preserving any rights
under this Agreement and the other Secured Debt Documents to which such
Guarantor is a party, including, without limitation, the fees and disbursements
of counsel (including the allocated fees and expenses of in-house counsel) to
the Collateral Trustee.

         (b)      Each Guarantor agrees to pay, and to save the Collateral
Trustee harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all stamp, excise, sales or other taxes which
may be payable or determined to be payable in connection with any of the
transactions contemplated by this Agreement.

         (c)      Each Guarantor agrees to pay, and to save the Collateral
Trustee harmless from, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement to the extent the Company would
be required to do so pursuant to Section 7.7 of the Collateral Trust Agreement.

         (d)      The maximum liability of each Guarantor under this Section 8.4
shall be limited to such Guarantor's ownership interests in CCEC pledged to the
Collateral Trustee, for the benefit of the Secured Parties, pursuant to the
Guarantor Pledge Agreement. The agreements in this Section 8.4 shall survive
repayment of the Secured Obligations and all other amounts payable under the
Secured Debt Documents.

         8.5      Successors and Assigns. This Agreement shall be binding upon
the successors and assigns of each Grantor and shall inure to the benefit of the
Collateral Trustee and the Secured Parties and their successors and assigns;
provided that no Grantor may assign, transfer or delegate any of its rights or
obligations under this Agreement without the prior written consent of the
Collateral Trustee.

Collateral Trustee at any time and from time to time while an Actionable Default
shall have occurred and be continuing, without notice to such Grantor or any
other Grantor, any such notice being expressly waived by each Grantor, to
set-off and appropriate and apply any and all deposits (general or special, time

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,

unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.
