liability company, partnership, association or other entity in which such Person
and/or one or more Wholly Owned Subsidiaries of such Person has a 100% equity
interest.

          "Withdrawal Liability" means liability to a Multiemployer Plan as a
result of a complete or partial withdrawal from such Multiemployer Plan, as such
terms are defined in Part I of Subtitle E of Title IV of ERISA.

          SECTION 1.02. Classification of Loans and Borrowings. For purposes of
this Agreement, Loans may be classified and referred to by Type (e.g., an "ABR
Loan"). Borrowings also may be classified and referred to by Type (e.g., an "ABR
Borrowing").

          SECTION 1.03. Terms Generally. The definitions of terms herein shall
apply equally to the singular and plural forms of the terms defined. Whenever
the context may require, any pronoun shall include the corresponding masculine,
feminine and neuter forms. The words "include", "includes" and "including" shall
be deemed to be followed by the phrase "without limitation". The word "will"
shall be construed to have the same meaning and effect as the word "shall".
Unless the context requires otherwise (a) any definition of or reference to any
agreement, instrument or other document herein shall be construed as referring
to such agreement, instrument or other document as from time to time amended,
supplemented or otherwise modified (subject to any restrictions on such
amendments, supplements or modifications set forth herein or in any other Credit
Document), (b) any reference herein to any

                 Amended and Restated Revolving Credit Agreement

                                      -24-

Person shall be construed to include such Person's successors and assigns, (c)
the words "herein", "hereof" and "hereunder", and words of similar import, shall
be construed to refer to this Agreement in its entirety and not to any
particular provision hereof, (d) all references herein to Articles, Sections,
Exhibits and Schedules shall be construed to refer to Articles and Sections of,
and Exhibits and Schedules to, this Agreement and (e) the words "asset" and
"property" shall be construed to have the same meaning and effect and to refer
to any and all tangible and intangible assets and properties, including cash,
securities, accounts and contract rights.

          SECTION 1.04. Accounting Terms; GAAP; Annualization of Financial
Covenants. Except as otherwise expressly provided herein, all terms of an
accounting or financial nature shall be construed in accordance with GAAP, as in
effect from time to time; provided that, if the Borrower notifies the
Administrative Agent that the Borrower requests an amendment to any provision
hereof to eliminate or modify the effect of any change occurring after the date
hereof in GAAP or in the application or interpretation thereof on the operation
of such provision (or if the Administrative Agent notifies the Borrower that the
Required Lenders request an amendment to any provision hereof for such purpose),
regardless of whether any such notice is given before or after such change in
GAAP or in the application thereof, then such provision shall be interpreted on
the basis of GAAP as in effect and applied immediately before such change shall
have become effective until such notice shall have been withdrawn or such
provision amended in accordance herewith. To enable the ready and consistent
determination of compliance with the covenants set forth in Article VII, the
Borrower will not change the last day of its fiscal year from December 31, or
the last days of the first three fiscal quarters in each of its fiscal years
from March 31, June 30 and September 30, respectively. Notwithstanding anything
herein to the contrary, for purposes of calculating the Consolidated Leverage
Ratio, the Consolidated Interest Coverage Ratio, the Consolidated Fixed Charge
Coverage Ratio and the Consolidated EBITDA under Sections 7.09(a), 7.09(b),
7.09(c) and 7.09(d), respectively, as at the end of any fiscal quarter of the
Borrower ending prior to December 31, 2004, the components of each such ratio
(other than Funded Indebtedness for purposes of the Consolidated Leverage Ratio)
or Consolidated EBITDA, as the case may be, shall be determined for the
applicable Test Period and multiplied by (x) in the case of the Test Period
ending December 31, 2003, four, (y) in the case of the Test Period ending March
31, 2004, two and (z) in the case of the Test Period ending June 30, 2004, 4/3.

          SECTION 1.05. European Monetary Union. Each obligation hereunder of
any party hereto that is denominated in a Currency of a country that is not a
Participating Member State on the date hereof shall, effective from the date on
which such country becomes a Participating Member State, be redenominated in
euro in accordance with the legislation of the European Union applicable to the
European Monetary Union; provided that, if and to the extent that any such
legislation provides that any such obligation of any such party payable within
such Participating Member State by crediting an account of the creditor can be
paid by the debtor either in euro or such Currency, such party shall be entitled
to pay or repay such amount either in euro or in such Currency. If the basis of
accrual of interest or fees expressed in this Agreement with respect to an
Agreed Foreign Currency of any country that becomes a Participating Member State
after the date on which such currency becomes an Agreed Foreign Currency shall
be inconsistent with any convention or practice in the interbank market for the
basis of accrual of interest or fees in respect of the euro, such convention or
practice shall replace such expressed basis effective as of and from the date on
which such country becomes a Participating Member

State. Without prejudice to the respective liabilities of the Borrower or any of
its Subsidiaries to the Issuing Lenders and/or the Lenders and of the Issuing
Lenders and/or the Lenders to the Borrower under or pursuant to this Agreement,
each provision of this Agreement shall be subject to such reasonable changes of
construction as the Administrative Agent may from time to time reasonably
specify to be necessary or appropriate to reflect the introduction or changeover
to the euro in any country that becomes a Participating Member State after the
date hereof.

                                   ARTICLE II

                                   THE CREDITS

          SECTION 2.01. Commitments. Subject to the terms and conditions set
forth herein, each Lender severally but not jointly agrees to make Loans to the
Borrower from time to time during the Availability Period in an aggregate
principal amount that will not result in (a) such Lender's Credit Exposure
exceeding such Lender's Commitment or (b) the total Credit Exposures (including,
without duplication, the Existing Loans continued hereunder as Loans pursuant to
the last sentence of this Section, the Existing Letters of Credit continued
hereunder as Letters of Credit pursuant to Section 2.04(l) and the CHEL Letters
of Credit continued hereunder as Letters of Credit pursuant to Section 2.04(m))
exceeding the total Commitments. Within the foregoing limits and subject to the
terms and conditions set forth herein, the Borrower may borrow, prepay and
reborrow Loans. Subject to the terms and conditions hereof, the Existing Loans
outstanding on the Effective Date shall be continued as an ABR Loan hereunder on
the Effective Date by the Lenders, automatically and without any action on the
part of any Person, and as of the Effective Date each such Existing Loan shall
be deemed a Loan outstanding under this Agreement as of such date.

          SECTION 2.02. Loans and Borrowings.

          (a) Obligations of Lenders. Each Loan shall be made as part of a
Borrowing consisting of Loans of the same Type made by the Lenders ratably in
accordance with their respective Commitments. The failure of any Lender to make
any Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments of the Lenders are several
and no Lender shall be responsible for any other Lender's failure to make any
Loan hereunder.

          (b) Type of Loans. Subject to Section 2.12, each Borrowing shall be
constituted entirely of ABR Loans or Eurodollar Loans as the Borrower may
request in accordance herewith. Each Lender at its option may make any
Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not
affect the obligation of the Borrower to repay such Loan in accordance with the
terms of this Agreement.

          (c) Minimum Amounts; Limitation on Number of Borrowings. At the
commencement of the Interest Period for any Eurodollar Borrowing, such Borrowing
shall be in an aggregate amount of $2,000,000 or a larger multiple of $500,000.
At the time that each ABR Borrowing is made, such Borrowing shall be in an
aggregate amount equal to $1,000,000 or a

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -26-

larger multiple of $250,000; provided that an ABR Borrowing may be in an
aggregate amount that is equal to the entire unused balance of the total
Commitments or that is required to finance the reimbursement of an LC
Disbursement as contemplated by Section 2.04(f). Borrowings of more than one
Type may be outstanding at the same time; provided that there shall not at any
time be more than a total of ten Eurodollar Borrowings outstanding.

          SECTION 2.03. Requests for Borrowings. To request a Borrowing, the
Borrower shall notify the Administrative Agent of such request by telephone (a)
in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before the date of the proposed Borrowing or (b) in
the case of an ABR Borrowing, not later than 10:00 a.m., New York City time, on
the date of the proposed Borrowing. Each such telephonic Borrowing Request shall
be irrevocable and shall be confirmed promptly by hand delivery or telecopy to
the Administrative Agent of a written Borrowing Request in a form approved by
the Administrative Agent and signed by the Borrower. Each such telephonic and
written Borrowing Request shall specify the following information in compliance
with Section 2.02:

          (i) the aggregate amount of the requested Borrowing;

          (ii) the date of such Borrowing, which shall be a Business Day;

          (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
     Borrowing;

          (iv) in the case of a Eurodollar Borrowing, the Interest Period
     therefor, which shall be a period contemplated by the definition of the
     term "Interest Period"; and

          (v) the location and number of the Borrower's account to which funds
     are to be disbursed, which shall comply with the requirements of Section
     2.05.

If no election as to the Type of Borrowing is specified, then the requested
Borrowing shall be an ABR Borrowing. If no Interest Period is specified with
respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed
to have selected an Interest Period of one month's duration. Promptly following
receipt of a Borrowing Request in accordance with this Section, the
Administrative Agent shall advise each Lender of the details thereof and of the
amount of such Lender's Loan to be made as part of the requested Borrowing.

          SECTION 2.04. Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, in
addition to the Loans provided for in Section 2.01, the Borrower may request an
Issuing Lender to issue, at any time and from time to time during the
Availability Period, one or more Letters of Credit for account of the Borrower
denominated in Dollars or any Agreed Foreign Currency and in such form as is
acceptable to such Issuing Lender in its reasonable determination. Letters of
Credit issued or continued hereunder shall constitute utilization of the
Commitments. Any such Letter of Credit may be stated to be issued at the request
of a Subsidiary Guarantor, if requested by the Borrower.

<PAGE>

                                      -27-

          (b) Notice of Issuance, Amendment, Renewal or Extension. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an
outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or
transmit by electronic communication, if arrangements for doing so have been
approved by the relevant Issuing Lender) to the relevant Issuing Lender and the
Administrative Agent (reasonably in advance of the requested date of issuance,
amendment, renewal or extension) a notice requesting the issuance of a Letter of
Credit, or identifying the Letter of Credit to be amended, renewed or extended,
and specifying the date of issuance, amendment, renewal or extension (which
shall be a Business Day), the date on which such Letter of Credit is to expire
(which shall comply with Section 2.04(d)), the amount and Currency of such
Letter of Credit, the name and address of the beneficiary thereof and such other
information as shall be necessary to prepare, amend, renew or extend such Letter
of Credit. If requested by such Issuing Lender, the Borrower also shall submit a
letter of credit application on such Issuing Lender's standard form in
connection with any request for a Letter of Credit. In the event of any
inconsistency between the terms and conditions of this Agreement and the terms
and conditions of any form of letter of credit application or other agreement
submitted by the Borrower or any of its Subsidiaries to, or entered into by the
Borrower or any of its Subsidiaries with, the relevant Issuing Lender relating
to any Letter of Credit, the terms and conditions of this Agreement shall
control.

          (c) Limitations on Amounts. A Letter of Credit shall be issued,
amended, renewed or extended only if (and upon issuance, amendment, renewal or
extension of each Letter of Credit the Borrower shall be deemed to represent and
warrant that), after giving effect to such issuance, amendment, renewal or
extension (i) the total LC Exposures of the Issuing Lenders (determined for
these purposes without giving effect to the participations therein of the
Lenders pursuant to Section 2.04(e) and, without duplication, including the
aggregate undrawn face amount of the Existing Letters of Credit and the CHEL
Letters of Credit continued and outstanding hereunder as Letters of Credit
pursuant to Sections 2.04(l) and 2.04(m), respectively) shall not exceed
$30,000,000 and (ii) the total Credit Exposures shall not exceed the total
Commitments.

          (d) Expiration Date. Each Letter of Credit shall expire at or prior to
the close of business on the earlier of (i) the date twelve months after the
date of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, twelve months after the then-current expiration date of such
Letter of Credit) and (ii) the date that is five Business Days prior to the
Commitment Termination Date.

          (e) Participations. By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) by an Issuing
Lender, and without any further action on the part of such Issuing Lender or the
Lenders, such Issuing Lender hereby grants to each Lender, and each Lender
hereby acquires from such Issuing Lender, a participation in such Letter of
Credit equal to such Lender's Applicable Percentage of the aggregate amount
available to be drawn under such Letter of Credit. Each Lender acknowledges and
agrees that its obligation to acquire participations pursuant to this paragraph
in respect of Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or
extension of any Letter of Credit or the occurrence and continuance of a Default
or reduction or termination of the Commitments, and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever.

<PAGE>

                                      -28-

          In consideration and in furtherance of the foregoing, each Lender
hereby absolutely and unconditionally agrees, upon receipt of notice as provided
in paragraph (f) below, to pay to the Administrative Agent, for account of the
relevant Issuing Lender, an amount in Dollars equal to such Lender's Applicable
Percentage of (a) in the case of each Letter of Credit denominated in Dollars,
each LC Disbursement made by such Issuing Lender thereunder and (b) in case of
each Letter of Credit denominated in a Foreign Currency, the Dollar Equivalent
of each LC Disbursement made by such Issuing Lender thereunder, promptly upon
the request of such Issuing Lender at any time from the time of such LC
Disbursement until such LC Disbursement is reimbursed by the Borrower or at any
time after any reimbursement payment is required to be refunded to the Borrower
for any reason. Each such payment shall be made in the same manner as provided
in Section 2.05 with respect to Loans made by such Lender (and Section 2.05
shall apply, mutatis mutandis, to the payment obligations of the Lenders under
this Section and, without limiting the foregoing, each Lender agrees that if
such Lender shall fail to pay such amount to such Issuing Lender on the date of
such request, such Lender shall pay such Issuing Lender forthwith on demand
interest on such amount, for each day from and including the date of such
request to but excluding the date of payment thereof to such Issuing Lender, at
the Federal Funds Effective Rate), and the Administrative Agent shall promptly
pay to the relevant Issuing Lender the amounts so received by it from the
Lenders. Promptly following receipt by the Administrative Agent of any payment
from the Borrower pursuant to the next following paragraph, the Administrative
Agent shall distribute such payment to the relevant Issuing Lender or, to the
extent that the Lenders have made payments pursuant to this paragraph to
reimburse such Issuing Lender, then to such Lenders and such Issuing Lender as
their interests may appear. Any payment made by a Lender pursuant to this
paragraph to reimburse an Issuing Lender for any LC Disbursement shall not
constitute a Loan and shall not relieve the Borrower of its obligation to
reimburse such LC Disbursement.

          (f) Reimbursement. If an Issuing Lender shall make any LC Disbursement
in respect of a Letter of Credit denominated in Dollars, the Borrower shall
reimburse such Issuing Lender in respect of such LC Disbursement by paying to
the Administrative Agent an amount in Dollars equal to such LC Disbursement not
later than 12:00 noon, New York City time, on (i) the Business Day that the
Borrower receives notice of such LC Disbursement, if such notice is received
prior to 10:00 a.m., New York City time, or (ii) the Business Day immediately
following the day that the Borrower receives such notice, if such notice is not
received prior to such time, provided that, if such LC Disbursement is not less
than $1,000,000, the Borrower may, subject to the conditions to borrowing set
forth herein, request in accordance with Section 2.03 that such payment be
financed with an ABR Borrowing in an equivalent amount and, to the extent so
financed, the Borrower's obligation to make such payment shall be discharged and
replaced by the resulting ABR Borrowing. If the Borrower fails to make such
payment when due, the Administrative Agent shall notify each Lender of the
applicable LC Disbursement, the payment then due from the Borrower in respect
thereof and such Lender's Applicable Percentage thereof.

          If an Issuing Lender shall make any LC Disbursement in respect of a
Letter of Credit denominated in a Foreign Currency, the Borrower shall reimburse
such Issuing Lender in respect of such LC Disbursement by paying to such Issuing
Lender in the Currency in which such Letter of Credit is denominated an amount
equal to such LC Disbursement not later than

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -29-

12:00 noon, Local Time of such Issuing Lender, on (i) the Business Day that the
Borrower receives notice of such LC Disbursement, if such notice is received
prior to 10:00 a.m., Local Time of such Issuing Lender, or (ii) the Business Day
immediately following the day that the Borrower receives such notice, if such
notice is not received prior to such time. Such Issuing Lender shall promptly
notify the Administrative Agent of the amount and date of each such
reimbursement.

          If the Borrower fails to make such payment when due, the
Administrative Agent shall notify each Lender of the applicable LC Disbursement,
the payment then due from the Borrower in respect thereof and such Lender's
Applicable Percentage thereof.

          Without limiting the other obligations of the Borrower hereunder, the
Borrower hereby agrees to indemnify each Issuing Lender of a Letter of Credit
denominated in a Foreign Currency for any and all costs, expenses and losses
incurred by it as a result of receiving payment or reimbursement for any LC
Disbursement thereunder from any Person in a Currency other than the Currency in
which such Letter of Credit was originally denominated. Any such amount payable
to any Issuing Lender shall be payable promptly after demand by such Issuing
Lender.

          (g) Obligations Absolute. The Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (f) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit, or any term or provision therein, (ii) any draft or other document
presented under a Letter of Credit proving to be forged, fraudulent or invalid
in any respect or any statement therein being untrue or inaccurate in any
respect, (iii) payment by any Issuing Lender under a Letter of Credit issued by
it against presentation of a draft or other document that does not comply
strictly with the terms of such Letter of Credit, and (iv) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section, constitute a legal or equitable
discharge of the Borrower's obligations hereunder.

          Neither the Administrative Agent, the Lenders nor any Issuing Lender,
nor any of their Related Parties, shall have any liability or responsibility by
reason of or in connection with the issuance or transfer of any Letter of Credit
by any Issuing Lender or any payment or failure to make any payment thereunder
(irrespective of any of the circumstances referred to in the preceding
sentence), or any error, omission, interruption, loss or delay in transmission
or delivery of any draft, notice or other communication under or relating to any
Letter of Credit (including any document required to make a drawing thereunder),
any error in interpretation of technical terms or any consequence arising from
causes beyond the control of any Issuing Lender; provided that the foregoing
shall not be construed to excuse any Issuing Lender from liability to the
Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by the Borrower to the
extent permitted by applicable law) suffered by the Borrower that are caused by
such Issuing Lender's gross negligence or willful misconduct when determining
whether drafts and other documents presented under a Letter of Credit comply
with the terms thereof. The parties hereto expressly agree that:

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -30-

          (i) any Issuing Lender may accept documents that appear on their face
     to be in substantial compliance with the terms of a Letter of Credit issued
     by it without responsibility for further investigation, regardless of any
     notice or information to the contrary, and may make payment upon
     presentation of documents that appear on their face to be in substantial
     compliance with the terms of such Letter of Credit;

          (ii) any Issuing Lender shall have the right, in its sole discretion,
     to decline to accept such documents and to make such payment if such
     documents are not in strict compliance with the terms of a Letter of Credit
     issued by it; and

          (iii) this sentence shall establish the standard of care to be
     exercised by the Issuing Lenders when determining whether drafts and other
     documents presented under a Letter of Credit comply with the terms thereof
     (and the parties hereto hereby waive, to the extent permitted by applicable
     law, any standard of care inconsistent with the foregoing).

          (h) Disbursement Procedures. Each Issuing Lender shall, within a
reasonable time following its receipt thereof, examine all documents purporting
to represent a demand for payment under a Letter of Credit issued by it. Such
Issuing Lender shall promptly after such examination notify the Administrative
Agent and the Borrower by telephone (confirmed by telecopy) of such demand for
payment and whether such Issuing Lender has made or will make an LC Disbursement
thereunder; provided that any failure to give or delay in giving such notice
shall not relieve the Borrower of its obligation to reimburse such Issuing
Lender and the Lenders with respect to any such LC Disbursement.

          (i) Interim Interest. If any Issuing Lender shall make any LC
Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Borrower reimburses such LC
Disbursement, at (x) if such amount is denominated in Dollars, the rate per
annum then applicable to ABR Loans or (y) if such amount is denominated in a
Foreign Currency, at the overnight London interbank offered rate determined by
the Administrative Agent in good faith; provided that, if the Borrower fails to
reimburse such LC Disbursement when due pursuant to paragraph (f) of this
Section, then Section 2.11(c) shall apply. Interest accrued pursuant to this
paragraph shall be for account of the relevant Issuing Lender, except that
interest accrued on and after the date of payment by any Lender pursuant to
paragraph (f) of this Section to reimburse such Issuing Lender shall be for
account of such Lender to the extent of such payment.

          (j) Replacement of Issuing Lenders. Any Issuing Lender may be replaced
at any time by written agreement between the Borrower, the Administrative Agent,
the replaced Issuing Lender and a successor Issuing Lender. The Administrative
Agent shall notify the Lenders of any such replacement of any Issuing Lender. At
the time any such replacement shall become effective, the Borrower shall pay all
unpaid fees accrued for account of the replaced Issuing Lender pursuant to
Section 2.10(b). From and after the effective date of any such replacement, (i)
the successor Issuing Lender shall have all the rights and obligations of the
replaced Issuing

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -31-

Lender under this Agreement with respect to Letters of Credit to be issued
thereafter and (ii) references herein to the term "Issuing Lender" shall be
deemed to include such successor or to any previous Issuing Lender, or to such
successor and all previous Issuing Lenders, as the context shall require. After
the replacement of an Issuing Lender hereunder, the replaced Issuing Lender
shall remain a party hereto and shall continue to have all the rights and
obligations of an Issuing Lender under this Agreement with respect to Letters of
Credit issued by it prior to such replacement, but shall not be required to
issue additional Letters of Credit.

          (k) Cash Collateralization. If either (i) an Event of Default shall
occur and be continuing and the Borrower receives notice from the Required
Lenders (or the Administrative Agent acting upon instructions of the Required
Lenders) (or, if the Loans have been accelerated, Lenders with LC Exposure
representing more than 50% of the total LC Exposure) demanding the deposit of
cash collateral pursuant to this paragraph, or (ii) the Borrower shall be
required to provide cover for LC Exposure pursuant to Section 2.09(b), the
Borrower shall immediately deposit into the Collateral Account, an amount in
cash equal to (x) in the case of an Event of Default, the total LC Exposures as
of such date plus, in each case, any accrued and unpaid interest thereon plus 5%
of the LC Exposure as of such date with respect to all Letters of Credit
denominated in any Foreign Currency or (y) in the case of cover pursuant to
Section 2.09(b), the amount required under Section 2.09(b); provided that the
obligation to deposit such cash collateral shall become effective immediately,
and such deposit shall become immediately due and payable, without demand or
other notice of any kind, upon the occurrence of any Event of Default with
respect to the Borrower described in clause (h) or (i) of Article VIII. Such
deposit shall be held by the Administrative Agent in the Collateral Account (or
a sub-account thereof) as collateral in the first instance for the LC Exposure
under this Agreement and thereafter for the payment of the other "Secured
Obligations" under (and as defined in) the Collateral Agency and Intercreditor
Agreement, and for these purposes the Borrower hereby grants a security interest
to the Administrative Agent for the benefit of the Lenders in the Collateral
Account and in any financial assets (as defined in the Uniform Commercial Code)
or other property held therein.

          (l) Continuation of Existing Letters of Credit. Subject to the terms
and conditions hereof, each Existing Letter of Credit outstanding on the
Effective Date shall be continued hereunder on the Effective Date by the Issuing
Lender, automatically and without any action on the part of any Person, and as
of the Effective Date the Lenders shall acquire a ratable participation therein
in accordance with their respective Commitments as if such Existing Letter of
Credit were originally issued hereunder, and each such Existing Letter of Credit
shall be deemed a Letter of Credit under this Agreement.

          (m) Continuation of CHEL Letters of Credit. Subject to the terms and
conditions hereof, in addition to the Letters of Credit issued or continued
hereunder for account of the Borrower, each Letter of Credit issued for the
account of CHEL under the 1999 Credit Agreement and outstanding on the Effective
Date shall be continued hereunder as of the Effective Date by the CHEL Issuing
Lender, automatically and without any action on the part of any Person, and as
of the Effective Date the Lenders shall acquire a ratable participation therein
in accordance with their respective Commitments as if such Letter of Credit were
originally issued hereunder (and in any amounts from time to time held as cash
collateral by the CHEL Issuing Lender in respect of the CHEL Letters of Credit
issued for the account of CHEL under the 1999 Credit Agreement), and each such
Letter of Credit shall be deemed a Letter of Credit

                                      -32-

under this Agreement. Notwithstanding the foregoing, neither the CHEL Issuing
Lender nor any Lender shall have any obligations to issue any new Letters of
Credit for the account of CHEL or otherwise extend any credit to CHEL hereunder
or otherwise; provided that (i) notwithstanding the foregoing, but subject to
the terms and conditions hereof, upon request of the Borrower, the CHEL Issuing
Lender may agree to amend, extend or renew any CHEL Letter of Credit hereunder
without any consent or approval of the Lenders (and the Lenders' liability
hereunder with respect to such CHEL Letter of Credit shall apply to such CHEL
Letter of Credit as so amended, extended or renewed, as applicable) and (ii)
upon request of the Borrower or CHEL (through the Borrower), the CHEL Issuing
Lender may issue a new Letter of Credit hereunder for the account of the
Borrower solely to replace a then existing CHEL Letter of Credit, provided that
such replacement Letter of Credit shall be in a face amount not in excess of
such existing CHEL Letter of Credit and in Dollars or in such currency (other
than Dollars) of such existing CHEL Letter of Credit and otherwise comply with
the requirements of this Section. Notwithstanding anything herein or in any
other Credit Documents or otherwise to the contrary, the Borrower agrees and
acknowledges that it shall be fully, unconditionally and absolutely liable with
respect to the CHEL Letters of Credit (as in effect on the Effective Date or
issued at any time thereafter in accordance with this Section, and as amended
and/or renewed from time to time) as if the Borrower were named as the account
party thereof. Nothing herein shall impair in any way the liability of CHEL with
respect to the CHEL Letters of Credit.

          SECTION 2.05. Funding of Borrowings.

          (a) Funding by Lenders. Each Lender shall make each Loan to be made by
it hereunder on the proposed date thereof by wire transfer of immediately
available funds by 1:00 noon, New York City time, to the account of the
Administrative Agent most recently designated by it for such purpose by notice
to the Lenders. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to an
account of the Borrower maintained with the Administrative Agent in New York
City and designated by the Borrower in the applicable Borrowing Request;
provided that ABR Borrowings made to finance the reimbursement of an LC
Disbursement as provided in Section 2.04(f) shall be remitted by the
Administrative Agent to the relevant Issuing Lender.

          (b) Presumption by the Administrative Agent. Unless the Administrative
Agent shall have received notice from a Lender prior to the proposed date of any
Borrowing that such Lender will not make available to the Administrative Agent
such Lender's share of such Borrowing, the Administrative Agent may assume that
such Lender has made such share available on such date in accordance with
paragraph (a) of this Section and may, in reliance upon such assumption, make
available to the Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Borrowing available to the
Administrative Agent, then the applicable Lender and the Borrower severally
agree to pay to the Administrative Agent forthwith on demand such corresponding
amount with interest thereon, for each day from and including the date such
amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Lender, the Federal Funds
Effective Rate or (ii) in the case of the Borrower, the interest rate applicable
to ABR Loans. If such Lender pays such amount to the Administrative Agent, then
such amount shall constitute such Lender's Loan included in such Borrowing.

          SECTION 2.06. Interest Elections.

          (a)  Elections by the Borrower for Borrowings. Each Borrowing
     initially shall be of the Type specified in the applicable Borrowing
     Request and, in the case of a Eurodollar Borrowing, shall have the Interest
     Period specified in such Borrowing Request. Thereafter, the Borrower may
     elect to convert such Borrowing to a Borrowing of a different Type or to
     continue such Borrowing as a Borrowing of the same Type and, in the case of
     a Eurodollar Borrowing, may elect the Interest Period therefor, all as
     provided in this Section. The Borrower may elect different options with
     respect to different portions of the affected Borrowing, in which case each
     such portion shall be allocated ratably among the Lenders holding the Loans
     constituting such Borrowing, and the Loans constituting each such portion
     shall be considered a separate Borrowing.

          (b)  Notice of Elections. To make an election pursuant to this
     Section, the Borrower shall notify the Administrative Agent of such
     election by telephone by the time that a Borrowing Request would be
     required under Section 2.03 if the Borrower were requesting a Borrowing of
     the Type resulting from such election to be made on the effective date of
     such election. Each such telephonic Interest Election Request shall be
     irrevocable and shall be confirmed promptly by hand delivery or telecopy to
     the Administrative Agent of a written Interest Election Request in a form
     approved by the Administrative Agent and signed by the Borrower.

          (c)  Information in Interest Election Requests. Each telephonic and
     written Interest Election Request shall specify the following information
     in compliance with Section 2.02:

               (i)   the Borrowing to which such Interest Election Request
          applies and, if different options are being elected with respect
          to different portions thereof, the portions thereof to be
          allocated to each resulting Borrowing (in which case the
          information to be specified pursuant to clauses (iii) and (iv) of
          this paragraph shall be specified for each resulting Borrowing);

               (ii)  the effective date of the election made pursuant to such
          Interest Election Request, which shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing
          or a Eurodollar Borrowing; and

               (iv)  if the resulting Borrowing is a Eurodollar Borrowing, the
          Interest Period therefor after giving effect to such election, which
          shall be a period contemplated by the definition of the term "Interest
          Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

<PAGE>

                                      -34-

          (d) Notice by the Administrative Agent to Lenders. Promptly following
receipt of an Interest Election Request, the Administrative Agent shall advise
each Lender of the details thereof and of such Lender's portion of each
resulting Borrowing.

          (e) Failure to Elect; Events of Default. If the Borrower fails to
deliver a timely Interest Election Request with respect to a Eurodollar
Borrowing prior to the end of the Interest Period therefor, then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary
provision hereof, if an Event of Default has occurred and is continuing and the
Administrative Agent, at the request of the Required Lenders, so notifies the
Borrower, then, so long as an Event of Default is continuing (i) no outstanding
Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii)
unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing
at the end of the Interest Period therefor.

          (f) Limitations on Lengths of Interest Periods. Notwithstanding any
other provision of this Agreement, the Borrower shall not be entitled to
request, or to elect to convert to or continue as a Eurodollar Borrowing any
Borrowing if the Interest Period requested therefor would end after the
Commitment Termination Date.

          SECTION 2.07. Termination and Reduction of the Commitments.

          (a) Scheduled Termination. Unless previously terminated the
Commitments shall terminate on the Commitment Termination Date.

          (b) Voluntary Termination or Reduction. The Borrower may at any time
terminate, or from time to time reduce, the Commitments; provided that (i) each
reduction of the Commitments pursuant to this Section shall be in an amount that
is $5,000,000 or a larger multiple of $1,000,000 and (ii) the Borrower shall not
terminate or reduce the Commitments if, after giving effect to any concurrent
prepayment of the Loans in accordance with Section 2.09, the total Credit
Exposures would exceed the total Commitments.

          (c) Notice of Voluntary Termination or Reduction. The Borrower shall
notify the Administrative Agent of any election to terminate or reduce the
Commitments under paragraph (b) of this Section at least three Business Days
prior to the effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any
notice, the Administrative Agent shall advise the Lenders of the contents
thereof. Each notice delivered by the Borrower pursuant to this Section shall be
irrevocable.

          (d) Effect of Termination or Reduction. Any termination or reduction
of the Commitments shall be permanent. Each reduction of the Commitments shall
be made ratably among the Lenders in accordance with their respective
Commitments.

          SECTION 2.08. Repayment of Loans; Evidence of Debt.

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -35-

          (a) Repayment. The Borrower hereby unconditionally promises to repay
the Loans to the Administrative Agent for account of the Lenders the outstanding
principal amount of the Loans on the Commitment Termination Date.

          (b) Maintenance of Records by the Lenders. Each Lender shall maintain
in accordance with its usual practice records evidencing the indebtedness of the
Borrower to such Lender resulting from each Loan made by such Lender, including
the amounts of principal and interest payable and paid to such Lender from time
to time hereunder.

          (c) Maintenance of Records by the Administrative Agent. The
Administrative Agent shall maintain records in which it shall record (i) the
amount of each Loan made hereunder, the Type thereof and each Interest Period
therefor, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for account of
the Lenders and each Lender's share thereof.

          (d) Effect of Entries. The entries made in the records maintained
pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence
of the existence and amounts of the obligations recorded therein; provided that
the failure of any Lender or the Administrative Agent to maintain such records
or any error therein shall not in any manner affect the obligation of the
Borrower to repay the Loans in accordance with the terms of this Agreement.

          (e) Promissory Notes. Any Lender may request that Loans made by it be
evidenced by a promissory note. In such event, the Borrower shall prepare,
execute and deliver to such Lender a promissory note payable to the order of
such Lender (or, if requested by such Lender, to such Lender and its registered
assigns) and in a form approved by the Administrative Agent. Thereafter, the
Loans evidenced by such promissory note and interest thereon shall at all times
(including after assignment pursuant to Section 10.04) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

          SECTION 2.09. Prepayment of Loans.

          (a) Optional Prepayments. The Borrower shall have the right at any
time and from time to time to prepay any Borrowing in whole or in part.

          (b) Mandatory Prepayments.

          (i) Credit Exposure Exceeding Commitments. If at any time the total
     Credit Exposures exceed the total Commitments, the Borrower shall forthwith
     prepay the Loans (and/or provide cover for LC Exposure as specified in
     Section 2.04(k)) in an aggregate amount equal to any such excess. Any
     prepayment pursuant to this clause (i) shall be applied, first, to Loans
     outstanding and, next, as cover for LC Exposure.

          (ii) Currency Fluctuation. On each Quarterly Date and promptly upon
     the receipt by the Administrative Agent of a Currency Valuation Notice, the
     Administrative Agent shall determine the sum (the "Aggregate Dollar Credit
     Exposure") of the total Credit

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -36-

     Exposures with respect to the Loans and all Letters of Credit denominated
     in Dollars plus the aggregate Dollar Amount of all Letters of Credit
     denominated in any Foreign Currency. Upon making such determination, the
     Administrative Agent shall promptly notify the Lenders and the Borrower
     thereof. If, on the date of such determination the Aggregate Dollar Credit
     Exposure exceeds the total Commitments as then in effect, the Borrower
     shall, on the date of such determination, prepay the Loans (and/or provide
     cover for LC Exposure as specified in Section 2.05(k)) in an aggregate
     amount equal to such excess. For purposes hereof, "Currency Valuation
     Notice" means a notice given by the Required Lenders or by any Issuing
     Lender to the Administrative Agent stating that such notice is a "Currency
     Valuation Notice" and requesting that the Administrative Agent determine
     the then Aggregate Dollar Credit Exposure. Unless an Event of Default shall
     have occurred and be continuing, the Administrative Agent shall not be
     required to make more than one valuation determination pursuant to Currency
     Valuation Notices within any rolling three month period. Any prepayment
     pursuant to this clause (ii) shall be applied, first, to Loans outstanding
     and, next, as cover for LC Exposure.

          (iii) Equity Issuance. Within 5 Business Days of receipt by the
     Borrower or any of its Subsidiaries of any cash proceeds from any Equity
     Issuance after the Effective Date, the Commitments shall be subject to
     automatic reduction and/or the Borrower shall prepay the Loans (and/or
     provide cover for LC Exposure as specified in Section 2.04(k)), in an
     aggregate amount equal to 50% of the Net Cash Proceeds of such Equity
     Issuance, such reduction and/or prepayment to be effected in each case
     solely to the extent specified in clause (vii) of this paragraph; provided
     that, notwithstanding the foregoing, with respect to any Equity Issuance
     resulting from the exercise of the warrants issued under the Warrant
     Agreement the Borrower shall be required to make such prepayment within 30
     Business Days after receipt of the Net Cash Proceeds thereof and only at
     such time(s) the amount so received (together with all such amounts
     previously received that have not been applied by the Borrower under this
     clause (iii)) shall exceed $100,000.

          (iv)  Debt Incurrence. Within 5 Business Days of receipt by the
     Borrower or any of its Subsidiaries of any cash proceeds from any Debt
     Incurrence (excluding any Indebtedness incurred in accordance with Section
     7.01) after the Effective Date, the Commitments shall be subject to
     automatic reduction and/or the Borrower shall prepay the Loans (and/or
     provide cover for LC Exposure as specified in Section 2.04(k)), in an
     aggregate amount equal to 100% of the Net Cash Proceeds thereof, such
     reduction and/or prepayment to be effected in each case solely to the
     extent specified in clause (vii) of this paragraph.

          (v)   Dispositions and Casualty Events. Within 5 Business Days of
     receipt by the Borrower or any of its Subsidiaries of any cash proceeds
     from any Disposition or Casualty Event, then, unless the Borrower shall
     have delivered a Reinvestment Notice in respect thereof to the
     Administrative Agent, to the extent the Net Cash Proceeds of such
     Disposition or Casualty Event, as the case may be, when combined with the
     Net Cash Proceeds of all other Dispositions and Casualty Events occurring
     during the then current fiscal year as to which a prepayment has not yet
     been made under this clause (v), are in excess of $5,000,000, the
     Commitments shall be subject to automatic reduction and/or the Borrower
     shall prepay the Loans (and/or provide cover for LC Exposure as specified

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -37-

     in Section 2.04(k)), in an aggregate amount equal to that portion of the
     Net Cash Proceeds of such Disposition or Casualty Event, as the case may
     be, and such prior Dispositions and Casualty Events in excess of
     $5,000,000, such reduction and/or prepayment to be effected in each case to
     the extent specified in clause (vii) of this paragraph; provided that in
     the case of any Disposition or Casualty Event as to which the Borrower
     shall have delivered a Reinvestment Notice, thereafter on each Reinvestment
     Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with
     respect to the relevant Reinvestment Event shall be applied toward the
     reduction of the Commitments and/or prepayment of Loans solely to the
     extent specified in clause (vii) of this paragraph. Nothing in this
     paragraph shall be deemed to limit any obligation of the Borrower or any of
     its Subsidiaries pursuant to any of the Security Documents to remit to a
     collateral or similar account maintained by the Collateral Agent pursuant
     to any of the Security Documents the proceeds of insurance, condemnation
     award or other compensation received in respect of any Casualty Event
     affecting any property to the extent required by the terms thereof.

          (vi)  Excess Cash Flow. Not later than the date 90 days after the end
     of each fiscal year of the Borrower ending after the date hereof, the
     Commitments shall be subject to automatic reduction and/or the Borrower
     shall prepay the Loans (and/or provide cover for LC Exposure as specified
     in Section 2.04(k)), in an aggregate amount equal to (i) 50% of Excess Cash
     Flow for such fiscal year minus (ii) the sum of, without duplication, (x)
     the aggregate amount of all optional prepayments of the Loans during such
     fiscal year, but only to the extent accompanied by a permanent reduction of
     the Commitments, (y) the aggregate amount of all optional prepayments of
     the Term Loans during such fiscal year and (z) the aggregate amount of all
     regularly scheduled principal payments of the Term Loans made during such
     fiscal year, such prepayment and/or reduction to be effected solely in each
     case to the extent specified in clause (vii) of this paragraph; provided
     that no mandatory prepayment shall be required under this clause (vi) if
     such sum for any fiscal year shall be less than $1,000,000.

          (vii) Application. The reductions of Commitments and/or prepayments
     pursuant to clauses (iii), (iv), (v) and (vi) of this Section 2.09(b) shall
     be applied to reduce the aggregate amount of the Commitments (and to the
     extent that, after, giving effect to such reduction, the total Credit
     Exposures would exceed the Commitments, the Borrower shall first, prepay
     the Loans and next, provide cover for LC Exposure as specified in Section
     2.04(k)). Notwithstanding the foregoing:

                (x) except as provided in clause (z) below, no such reduction
          and/or prepayment under any of such clauses (iii), (iv), (v) and (vi)
          shall be required until the Term Loans have been paid in full;

                (y) if at the time of the application of any such amount any
          event or condition which upon notice, lapse of time or both would,
          unless cured or waived, become an Event of Default (a "Potential Event
          of Default") has occurred and is continuing, the amounts subject to
          the mandatory prepayment requirements hereunder and under the Term
          Loan Agreement shall not be applied to the prepayment of the Term
          Loans (to the extent required under the Term Loan

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -38-

          Agreement), but rather shall be paid by the Borrower or the relevant
          Subsidiary to, and held in escrow by, the Administrative Agent until
          such earlier time as an Event of Default has occurred as a result of
          such event or condition or such Potential Event of Default has been
          waived or cured; provided that (A) if at any time such Potential Event
          of Default shall be waived or cured, such amounts shall be forthwith
          applied to the prepayment to the Term Loans (but only to the extent
          required under the Term Loan Agreement) and (B) if such an Event of
          Default occurs, such amounts shall be applied solely in accordance
          with clause (z) below; and

                (z) if at the time of application of any amount subject to the
          mandatory prepayment requirements hereunder and under the Term Loan
          Agreement any Event of Default has occurred and is continuing, such
          amount shall not be applied to the prepayment of the Term Loans (to
          the extent required under the Term Loan Agreement), but rather shall
          be applied to the reduction of the Commitments and/or the prepayments
          (and/or the provision of cash cover for the LC Exposures) in
          accordance with the first sentence of this paragraph (vii).

          (c)   Notices, etc. The Borrower shall notify the Administrative Agent
by telephone (confirmed by telecopy) of any prepayment hereunder (other than a
mandatory prepayment under Section 2.09(b)(i)) (i) in the case of prepayment of
a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three
Business Days before the date of prepayment or (ii) in the case of prepayment of
an ABR Borrowing, not later than 10:00 a.m., New York City time, on the date of
prepayment. Each such notice shall be irrevocable and shall specify the
prepayment date, the principal amount of each Borrowing or portion thereof to be
prepaid and, in the case of a mandatory prepayment, a reasonably detailed
calculation of the amount of such prepayment. Promptly following receipt of any
such notice relating to a Borrowing, the Administrative Agent shall advise the
Lenders of the contents thereof. Each partial prepayment of any Borrowing shall
be in an amount that would be permitted in the case of an advance of a Borrowing
of the same Type as provided in Section 2.02, except as necessary to apply the
fully required amount of a mandatory prepayment. Each prepayment of a Borrowing
shall be applied ratably to the Loans included in the prepaid Borrowing.
Prepayments shall be accompanied by accrued interest to the extent required by
Section 2.11.

          SECTION 2.10. Fees.

          (a)   Commitment Fee. The Borrower agrees to pay to the Administrative
Agent for account of each Lender a commitment fee, which shall accrue at a rate
per annum equal to 0.375% on the average daily unused amount of the Commitment
of such Lender during the period from and including the Effective Date hereof to
but excluding the Commitment Termination Date. Commitment fees accrued through
and including each Quarterly Date shall be payable in arrears on the third
Business Day following such Quarterly Date and on the earlier of the date the
Commitment terminates and the Commitment Termination Date, commencing on the
first such date to occur after the date hereof. All commitment fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). For
purposes of computing commitment fees with

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -39-

respect to the Commitments, the Commitment of a Lender shall be deemed to be
used to the extent of the outstanding Loans and LC Exposure of such Lender.

          (b) Letter of Credit Fees. The Borrower agrees to pay (i) to the
Administrative Agent for account of each Lender a participation fee with respect
to its participations in Letters of Credit (including the CHEL Letters of
Credit), which shall accrue at a rate per annum equal to the Applicable Margin
applicable to interest on Eurodollar Loans on the average daily amount of such
Lender's LC Exposure (excluding any portion thereof attributable to unreimbursed
LC Disbursements) during the period from and including the Effective Date to but
excluding the later of the date on which such Lender's Commitment terminates and
the date on which such Lender ceases to have any LC Exposure, and (ii) to each
Issuing Lender for its own account a fronting fee in respect of each Letter of
Credit issued by it, which shall accrue at the rate per annum, as mutually
agreed between the Borrower and such Issuing Lender, on the average daily amount
of the aggregate undrawn amount of such Letter of Credit plus the aggregate
amount of all LC Disbursements in respect thereof that have not yet been
reimbursed by or on behalf of the Borrower during the period from and including
the Effective Date to but excluding the later of the date of termination of the
Commitments and the date on which there ceases to be any exposure with respect
to such Letter of Credit, as well as such Issuing Lender's standard fees with
respect to the issuance, amendment, renewal or extension of any Letter of Credit
or processing of drawings thereunder. Participation fees and fronting fees
accrued through and including each Quarterly Date shall be payable in arrears on
the third Business Day following such Quarterly Date, commencing on the first
such date to occur after the Effective Date; provided that all such fees shall
be payable on the date on which the Commitments terminate and any such fees
accruing after the date on which the Commitments terminate shall be payable on
demand. Any other fees payable to any Issuing Lender pursuant to this paragraph
shall be payable within three Business Days after demand. All participation fees
and fronting fees shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).

          (c) Administrative Agent Fees. The Borrower agrees to pay to the
Administrative Agent, for its own account, fees payable in the amounts and at
the times separately agreed upon between the Borrower and the Administrative
Agent.

          (d) Payment of Fees. All fees payable hereunder shall be paid on the
dates due, in immediately available funds, to the Administrative Agent (or to
any Issuing Lender, in the case of fees payable to it) for distribution, in the
case of commitment fees and participation fees, to the Lenders entitled thereto.
Fees paid shall not be refundable under any circumstances.

          SECTION 2.11. Interest.

          (a) ABR Loans. The Loans constituting each ABR Borrowing shall bear
interest at a rate per annum equal to the Alternate Base Rate plus the
Applicable Margin.

          (b) Eurodollar Loans. The Loans constituting each Eurodollar Borrowing
shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the
Interest Period for such Borrowing plus the Applicable Margin.

          (c) Default Interest. Notwithstanding the foregoing, (i) upon and
during the continuation of any Event of Default under Section 8.01(a) or (b) or
(ii) upon request of the Required Lenders, upon and during the continuation of
any other Event of Default, the aggregate principal amount of all Loans shall
bear interest, after as well as before judgment, at a rate per annum equal to 2%
plus the rate otherwise applicable to the respective Loans. In addition (but
without duplication of the amounts payable under the immediately preceding
sentence), if any principal of or interest on any Loan or any fee or other
amount payable by the Borrower hereunder is not paid when due, whether at stated
maturity, upon acceleration, by mandatory prepayment or otherwise, such overdue
amount shall bear interest, after as well as before judgment, at a rate per
annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided above or (ii) in the case of
any other amount, 2% plus the rate applicable to ABR Loans as provided in
paragraph (a) of this Section.

          (d) Payment of Interest. Accrued interest on each Loan shall be
payable in arrears on each Interest Payment Date for such Loan and upon
termination of the Commitments; provided that (i) interest accrued pursuant to
paragraph (c) of this Section shall be payable on demand, (ii) in the event of
any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan
prior to the Commitment Termination Date), accrued interest on the principal
amount repaid or prepaid shall be payable on the date of such repayment or
prepayment and (iii) in the event of any conversion of any Eurodollar Borrowing
prior to the end of the Interest Period therefor, accrued interest on such
Borrowing shall be payable on the effective date of such conversion.

          (e) Computation. All interest hereunder shall be computed on the basis
of a year of 360 days, except that interest computed by reference to the
Alternate Base Rate at times when the Alternate Base Rate is based on the Prime
Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap
year), and in each case shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). The applicable Alternate
Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent,
and such determination shall be conclusive absent manifest error.

          SECTION 2.12. Alternate Rate of Interest. If prior to the commencement
of the Interest Period for a EurodollarBorrowing:

          (a) the Administrative Agent determines (which determination shall be
     conclusive absent manifest error) that adequate and reasonable means do not
     exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or

          (b) the Administrative Agent is advised by the Required Lenders that
     the Adjusted LIBO Rate for such Interest Period will not adequately and
     fairly reflect the cost to such Lenders of making or maintaining their
     Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or

                Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -41-

continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing.

          SECTION 2.13. Increased Costs.

          (a) Increased Costs Generally. If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit or
     similar requirement against assets of, deposits with or for account of, or
     credit extended by, any Lender (except any such reserve requirement
     reflected in the Adjusted LIBO Rate) or any Issuing Lender; or

          (ii) impose on any Lender or any Issuing Lender or the London
     interbank market any other condition affecting this Agreement or Eurodollar
     Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lenders of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the
relevant Issuing Lender of participating in, issuing or maintaining any Letter
of Credit or to reduce the amount of any sum received or receivable by such
Lender or such Issuing Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender or such Issuing Lender, as
the case may be, such additional amount or amounts as will compensate such
Lender or such Issuing Lender, as the case may be, for such additional costs
incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or any Issuing Lender
determines that any Change in Law regarding capital requirements has or would
have the effect of reducing the rate of return on such Lender's or such Issuing
Lender's capital or on the capital of such Lender's or such Issuing Lender's
holding company, if any, as a consequence of this Agreement or the Loans made
by, or participations in Letters of Credit held by, such Lender, or the Letters
of Credit issued by such Issuing Lender, to a level below that which such Lender
or such Issuing Lender or such Lender's or such Issuing Lender's holding company
could have achieved but for such Change in Law (taking into consideration such
Lender's or such Issuing Lender's policies and the policies of such Lender's or
such Issuing Lender's holding company with respect to capital adequacy), then
from time to time the Borrower will pay to such Lender or such Issuing Lender,
as the case may be, such additional amount or amounts as will compensate such
Lender or such Issuing Lender or such Lender's or such Issuing Lender's holding
company for any such reduction suffered.

          (c) Certificates from Lenders. A certificate of a Lender, an Issuing
Lender setting forth the amount or amounts necessary to compensate such Lender
or such Issuing Lender or its holding company, as the case may be, as specified
in paragraph (a) or (b) of this Section shall be delivered to the Borrower and
shall be conclusive absent manifest error. The Borrower shall pay such Lender or
such Issuing Lender, as the case may be, the amount shown as due on any such
certificate within 30 days after receipt thereof.

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -42-

          (d) Delay in Requests. Failure or delay on the part of any Lender or
any Issuing Lender to demand compensation pursuant to this Section shall not
constitute a waiver of such Lender's or such Issuing Lender's right to demand
such compensation; provided that the Borrower shall not be required to
compensate a Lender, an Issuing Lender pursuant to this Section for any
increased costs or reductions incurred more than six months prior to the date
that such Lender or such Issuing Lender, as the case may be, notifies the
Borrower of the Change in Law giving rise to such increased costs or reductions
and of such Lender's or such Issuing Lender's intention to claim compensation
therefor; provided further that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the six-month period referred
to above shall be extended to include the period of retroactive effect thereof.

          SECTION 2.14. Break Funding Payments. In the event of (a) the payment
of any principal of any Eurodollar Loan other than on the last day of an
Interest Period therefor (including as a result of an Event of Default), (b) the
conversion of any Eurodollar Loan other than on the last day of an Interest
Period therefor, (c) the failure to borrow, convert, continue or prepay any Loan
on the date specified in any notice delivered pursuant hereto, or (d) the
assignment of any Eurodollar Loan other than on the last day of an Interest
Period therefor as a result of a request by the Borrower pursuant to Section
2.17, then, in any such event, the Borrower shall compensate each Lender for the
loss, cost and expense attributable to such event. In the case of a Eurodollar
Loan, the loss to any Lender attributable to any such event shall be deemed to
include an amount determined by such Lender to be equal to the excess, if any,
of (i) the amount of interest that such Lender would pay for a deposit equal to
the principal amount of such Loan for the period from the date of such payment,
conversion, failure or assignment to the last day of the then current Interest
Period for such Loan (or, in the case of a failure to borrow, convert or
continue, the duration of the Interest Period that would have resulted from such
borrowing, conversion or continuation) if the interest rate payable on such
deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii)
the amount of interest that such Lender would earn on such principal amount for
such period if such Lender were to invest such principal amount for such period
at the interest rate that would be bid by such Lender (or an Affiliate of such
Lender) for Dollar deposits from other banks in the eurodollar market at the
commencement of such period. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay such Lender the amount shown as due on
any such certificate within 30 days after receipt thereof.

          SECTION 2.15. Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower hereunder or under any other Credit Document
shall be made free and clear of and without deduction for any Indemnified Taxes
or Other Taxes; provided that if the Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section)
the Administrative Agent, each Lender and/or each Issuing Lender (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -43-

          (b) Payment of Other Taxes by the Borrower. In addition, the Borrower
shall pay any Other Taxes to the relevant Governmental Authority in accordance
with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent, each Lender and each Issuing Lender, within 30 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) paid by the Administrative
Agent, such Lender or such Issuing Lender, as the case may be, and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender, an Issuing Lender, or by the Administrative Agent on its
own behalf or on behalf of a Lender or an Issuing Lender, shall be conclusive
absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority,
the Borrower shall deliver to the Administrative Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Administrative Agent.

          (e) Foreign Lenders. Any Foreign Lender that is entitled to an
exemption from or reduction of withholding tax under the law of the jurisdiction
in which the Borrower is located, or any treaty to which such jurisdiction is a
party, with respect to payments under this Agreement shall deliver to the
Borrower (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law or reasonably requested by the Borrower, such
properly completed and executed documentation prescribed by applicable law as
will permit such payments to be made without withholding or at a reduced rate.

          SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs.

          (a) Payments by the Obligors. Each Obligor shall make each payment
required to be made by it hereunder (whether of principal, interest, fees or
reimbursement of LC Disbursements, or under Section 2.13, 2.14 or 2.15, or
otherwise) or under any other Credit Document (except to the extent otherwise
provided therein) prior to 12:00 noon, Local Time, on the date when due, in
immediately available funds in Dollars or (with respect to the reimbursement or
other obligation in respect of any Letter of Credit denominated in a Foreign
Currency) in such Foreign Currency, without set-off, counterclaim or other
deduction; provided that if a new Loan is to be made by any Lender on a date the
Borrower is to repay any principal of an outstanding Loan of such Lender, such
Lender shall apply the proceeds of such new Loan to the payment of the principal
to be repaid and only an amount equal to the difference between the principal to
be borrowed and the principal to be repaid shall be made available by such
Lender to the Administrative Agent as provided in Section 2.05 or paid by the
Borrower to the Administrative Agent pursuant to this paragraph, as the case may
be. Any amounts received after such time on any date may, in the discretion of
the Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -44-

thereon. All such payments shall be made to the Administrative Agent at its
offices at 270 Park Avenue, New York, New York, except as otherwise expressly
provided in the relevant Credit Document, and except payments to be made
directly to the relevant Issuing Lender as expressly provided herein and except
that payments pursuant to Sections 2.13, 2.14, 2.15 and 10.03 shall be made
directly to the Persons entitled thereto. The Administrative Agent shall
distribute any such payments received by it for account of any other Person to
the appropriate recipient promptly following receipt thereof. If any payment
hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day and, in the case of any
payment accruing interest, interest thereon shall be payable for the period of
such extension. All payments hereunder or under any other Credit Document
(except to the extent otherwise provided herein or therein) shall be made in
Dollars. Notwithstanding the foregoing, if the Borrower shall fail to pay any
reimbursement obligation in respect of any LC Disbursement denominated in a
Foreign Currency when due, such unpaid reimbursement obligation shall
automatically be redenominated in Dollars on the due date thereof in an amount
equal to the Dollar Equivalent thereof and such principal or reimbursement
obligation shall be payable on demand in such amount in Dollars; and if the
Borrower shall fail to pay interest on any LC Disbursement made pursuant to a
Letter of Credit that is denominated in a Foreign Currency, such interest shall
automatically be redenominated in Dollars on the due date therefor in an amount
equal to the Dollar Equivalent thereof on the date of such redenomination and
such interest shall be payable on demand.

          (b) Application of Insufficient Payments. If at any time insufficient
funds are received by and available to the Administrative Agent to pay fully all
amounts of principal, unreimbursed LC Disbursements, interest and fees then due
hereunder, such funds shall be applied (i) first, to pay interest and fees then
due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, and (ii) second, to pay
principal and unreimbursed LC Disbursements then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

          (c) Pro Rata Treatment. Except to the extent otherwise provided
herein: (i) each payment or prepayment of principal of Loans by the Borrower
shall be made for account of the relevant Lenders pro rata in accordance with
the respective unpaid principal amounts of the Loans held by them and (ii) each
payment of interest on Loans by the Borrower shall be made for account of the
relevant Lenders pro rata in accordance with the amounts of interest on such
Loans then due and payable to the respective Lenders.

          (d) Sharing of Payments by Lenders. If any Lender shall, by exercising
any right of set-off or counterclaim or otherwise, obtain payment in respect of
any principal of or interest on any of its Loans or participations in LC
Disbursements resulting in such Lender receiving payment of a greater proportion
of the aggregate amount of its Loans and participations in LC Disbursements and
accrued interest thereon then due than the proportion received by any other
Lender, then the Lender receiving such greater proportion shall purchase (for
cash at face value) participations in the Loans and participations in LC
Disbursements of other Lenders to the extent necessary so that the benefit of
all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans
and participations in LC Disbursements; provided that (i) if any such
participations are

                 Amended and Restated Revolving Credit Agreement

<PAGE>

purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by any Obligor pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans or participations
in LC Disbursements to any assignee or participant, other than to the Borrower
or any Subsidiary or Affiliate thereof (as to which the provisions of this
paragraph shall apply). Each Obligor consents to the foregoing and agrees, to
the extent it may effectively do so under applicable law, that any Lender
acquiring a participation pursuant to the foregoing arrangements may exercise
against such Obligor rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Obligor
in the amount of such participation.

          (e) Presumptions of Payment. Unless the Administrative Agent shall
have received notice from the Borrower prior to the date on which any payment is
due to the Administrative Agent for account of the Lenders or any Issuing Lender
hereunder that the Borrower will not make such payment, the Administrative Agent
may assume that the Borrower has made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the Lenders or
such Issuing Lender, as the case may be, the amount due. In such event, if the
Borrower has not in fact made such payment, then each of the Lenders or such
Issuing Lender, as the case may be, severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such
Lender or such Issuing Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the Federal Funds Effective Rate.

          (f) Certain Deductions by the Administrative Agent. If any Lender
shall fail to make any payment required to be made by it pursuant to Section
2.04(e) or (f), 2.05(b) or 2.16(e), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for account of such Lender to
satisfy such Lender's obligations under such Sections until all such unsatisfied
obligations are fully paid.

          SECTION 2.17. Mitigation Obligations; Replacement of Lenders.

          (a) Designation of a Different Lending Office. If any Lender requests
compensation under Section 2.13, or if the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for account of any
Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts
to designate a different lending office for funding or booking its Loans
hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant
to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not
subject such Lender to any unreimbursed cost or expense and would not otherwise
be disadvantageous to such Lender. The Borrower hereby agrees to pay all
reasonable costs and expenses incurred by any Lender in connection with any such
designation or assignment.

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -46-

          (b) Replacement of Lenders. If any Lender requests compensation under
Section 2.13, if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for account of any Lender pursuant to
Section 2.15, if any Lender defaults in its obligation to fund Loans hereunder,
or if a Lender refuses to consent to any amendment, modification or waiver of
this Agreement or any other Credit Document that pursuant to Section 10.02
requires consent of 100% of the Lenders directly affected thereby, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 10.04), all its interests, rights and obligations under this Agreement
to an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent (which
consent shall not unreasonably be withheld) with respect to such assignment (but
only to the extent such consent is required by Section 10.04(b)), (ii) such
Lender shall have received payment of an amount equal to the outstanding
principal of its Loans and participations in LC Disbursements, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and (iii) in the case
of any such assignment resulting from a claim for compensation under Section
2.13 or payments required to be made pursuant to Section 2.15, such assignment
will result in a reduction in such compensation or payments. A Lender shall not
be required to make any such assignment and delegation if, prior thereto, as a
result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

                                   ARTICLE III

                                    GUARANTEE

          SECTION 3.01. The Guarantee. (a) The Borrower hereby guarantees (and
hereby confirms its guarantee pursuant to the 1999 Credit Agreement) to the CHEL
Issuing Lender, each Lender and the Administrative Agent and their respective
successors and assigns, in each case as primary obligor and not merely as
surety, the prompt payment in full when due of all obligations of CHEL in
respect of the CHEL Letters of Credit, strictly in accordance with the terms
hereof (such obligations being herein collectively called the "CHEL Guaranteed
Obligations"). The Borrower hereby further agrees that if CHEL shall fail to pay
in full when due any of the CHEL Guaranteed Obligations, the Borrower will
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the CHEL
Guaranteed Obligations, the same will be promptly paid in full when due in
accordance with the terms of such extension or renewal.

          (b) The Subsidiary Guarantors hereby jointly and severally guarantee
to each Lender and the Administrative Agent and their respective successors and
assigns the prompt payment in full when due (whether at stated maturity, by
acceleration or otherwise) of the principal of and interest on the Loans made by
the Lenders to the Borrower and all other amounts from time to time owing to the
Lenders or the Administrative Agent by the Borrower and/or any other Obligor
under any of the Credit Documents, in each case strictly in accordance with the
terms thereof (such obligations being herein collectively called the "Guaranteed

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -47-

Obligations"). The Subsidiary Guarantors hereby further jointly and severally
agree that if the Borrower shall fail to pay in full when due (whether at stated
maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the
Subsidiary Guarantors will promptly pay the same, without any demand or notice
whatsoever, and that in the case of any extension of time of payment or renewal
of any of the Guaranteed Obligations, the same will be promptly paid in full
when due (whether at extended maturity, by acceleration or otherwise) in
accordance with the terms of such extension or renewal.

          SECTION 3.02. Obligations Unconditional. The obligations of the
Guarantors under Section 3.01 are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Borrower under this Agreement or any other agreement
or instrument referred to herein, or any substitution, release or exchange of
any other guarantee of or security for any of the CHEL Guaranteed Obligations or
the Guaranteed Obligations, and, to the fullest extent permitted by applicable
law, irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section that the obligations of the Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances. Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter
or impair the liability of the Guarantors hereunder, which shall remain absolute
and unconditional as described above:

          (i) at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     CHEL Guaranteed Obligations or Guaranteed Obligations shall be extended, or
     such performance or compliance shall be waived;

          (ii) any of the acts mentioned in any of the provisions of this
     Agreement or any other agreement or instrument referred to herein shall be
     done or omitted;

          (iii) the maturity of any of the CHEL Guaranteed Obligations or
     Guaranteed Obligations shall be accelerated or the CHEL Guaranteed
     Obligations or Guaranteed Obligations shall be modified, supplemented or
     amended in any respect, or any right under this Agreement or any other
     agreement or instrument referred to herein shall be waived or any other
     guarantee of any of the CHEL Guaranteed Obligations or Guaranteed
     Obligations or any security therefor shall be released or exchanged in
     whole or in part or otherwise dealt with;

          (iv) any lien or security interest granted to, or in favor of, the
     Administrative Agent or any Lender or Lenders as security for any of the
     CHEL Guaranteed Obligations or Guaranteed Obligations shall fail to be
     perfected; or

          (v) the insolvency of CHEL or the invalidity, unenforceability or
     illegality, or any other defect or defense related to, any of the
     obligations of CHEL in respect of the CHEL Letters of Credit.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Administrative
Agent or any Lender exhaust

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -48-

any right, power or remedy or proceed against the Borrower under this Agreement
or any other agreement or instrument referred to herein, or against any other
Person under any other guarantee of, or security for, any of the CHEL Guaranteed
Obligations or Guaranteed Obligations.

          SECTION 3.03. Reinstatement. The obligations of the Guarantors under
this Article shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of an Obligor in respect of the CHEL
Guaranteed Obligations or Guaranteed Obligations is rescinded or must be
otherwise restored by any holder of any of the CHEL Guaranteed Obligations or
Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and the Guarantors jointly and severally agree that
they will indemnify the Administrative Agent and each Lender on demand for all
reasonable costs and expenses (including reasonable fees of counsel) incurred by
the Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law, but
excluding any such costs and expenses determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of the Administrative Agent or such Lender, as
the case may be.

          SECTION 3.04. Subrogation. The Guarantors hereby jointly and severally
agree that until the payment and satisfaction in full of all CHEL Guaranteed
Obligations or Guaranteed Obligations and the expiration and termination of the
Commitments of the Lenders under this Agreement they shall not exercise any
right or remedy arising by reason of any performance by them of their guarantee
in Section 3.01, whether by subrogation or otherwise, against any Obligor or any
other guarantor of any of the CHEL Guaranteed Obligations or Guaranteed
Obligations or any security for any of the CHEL Guaranteed Obligations or
Guaranteed Obligations.

          SECTION 3.05. Remedies. The Guarantors jointly and severally agree
that, as between the Guarantors and the Lenders, the obligations of the Obligors
under this Agreement may be declared to be forthwith due and payable as provided
in Article VIII (and shall be deemed to have become automatically due and
payable in the circumstances provided in Article VIII) for purposes of Section
3.01 notwithstanding any stay, injunction or other prohibition preventing such
declaration (or such obligations from becoming automatically due and payable) as
against any Obligor and that, in the event of such declaration (or such
obligations being deemed to have become automatically due and payable), such
obligations (whether or not due and payable by such Obligor) shall forthwith
become due and payable by the Guarantors for purposes of Section 3.01.

          SECTION 3.06. Instrument for the Payment of Money. Each Guarantor
hereby acknowledges that the guarantee in this Article constitutes an instrument
for the payment of money, and consents and agrees that any Lender or the
Administrative Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to
bring motion-action under New York CPLR Section 3213.

                                      -49-

          SECTION 3.07. Continuing Guarantee. The guarantee in this Article is a
continuing guarantee, and shall apply to all CHEL Guaranteed Obligations or
Guaranteed Obligations whenever arising.

          SECTION 3.08. Rights of Contribution. The Subsidiary Guarantors hereby
agree, as between themselves, that if any Subsidiary Guarantor shall become an
Excess Funding Guarantor (as defined below) by reason of the payment by such
Subsidiary Guarantor of any Guaranteed Obligations, each other Subsidiary
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
next sentence), pay to such Excess Funding Guarantor an amount equal to such
Subsidiary Guarantor's Pro Rata Share (as defined below and determined, for this
purpose, without reference to the properties, debts and liabilities of such
Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of
such Guaranteed Obligations. The payment obligation of a Subsidiary Guarantor to
any Excess Funding Guarantor under this Section shall be subordinate and subject
in right of payment to the prior payment in full of the obligations of such
Subsidiary Guarantor under the other provisions of this Article and such Excess
Funding Guarantor shall not exercise any right or remedy with respect to such
excess until payment and satisfaction in full of all of such obligations.

          For purposes of this Section, (i) "Excess Funding Guarantor" means, in
respect of any Guaranteed Obligations, a Subsidiary Guarantor that has paid an
amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii)
"Excess Payment" means, in respect of any Guaranteed Obligations, the amount
paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such
Guaranteed Obligations and (iii) "Pro Rata Share" means, for any Subsidiary
Guarantor, the ratio (expressed as a percentage) of (x) the amount by which the
aggregate present fair saleable value of all properties of such Subsidiary
Guarantor (excluding any shares of stock of any other Subsidiary Guarantor)
exceeds the amount of all the debts and liabilities of such Subsidiary Guarantor
(including contingent, subordinated, unmatured and unliquidated liabilities, but
excluding the obligations of such Subsidiary Guarantor hereunder and any
obligations of any other Subsidiary Guarantor that have been Guaranteed by such
Subsidiary Guarantor) to (y) the amount by which the aggregate fair saleable
value of all properties of all of the Subsidiary Guarantors exceeds the amount
of all the debts and liabilities (including contingent, subordinated, unmatured
and unliquidated liabilities, but excluding the obligations of the Subsidiary
Guarantors hereunder and under the other Credit Documents) of all of the
Subsidiary Guarantors, determined (A) with respect to any Subsidiary Guarantor
that is a party hereto on the Effective Date, as of the Effective Date, and (B)
with respect to any other Subsidiary Guarantor, as of the date such Subsidiary
Guarantor becomes a Subsidiary Guarantor hereunder.

          SECTION 3.09. General Limitation on Guarantee Obligations. In any
action or proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Subsidiary Guarantor under
Section 3.01(b) would otherwise, taking into account the provisions of Section
3.08, be held or determined to be void, invalid or unenforceable, or
subordinated to the claims of any other creditors, on account of the amount of
its liability under Section 3.01(b), then, notwithstanding any other provision
hereof to the contrary, the amount of such liability shall, without any further
action by such Subsidiary Guarantor, any Lender, the Administrative Agent or any
other Person, be automatically limited and reduced to the highest amount that is

                                      -50-

valid and enforceable and not subordinated to the claims of other creditors as
determined in such action or proceeding.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

          The Borrower and each Subsidiary Guarantor (as to itself and its
Subsidiaries only) represents and warrants to the Lenders that:

          SECTION 4.01. Organization; Powers. Each of the Borrower and its
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization, (b) has all requisite power
and authority to carry on its business now conducted and (c) except where the
failure to do so, either individually or in the aggregate, could not reasonably
be expected to have a Material Adverse Effect, is duly qualified and is
authorized to do business and is in good standing in each jurisdiction where the
ownership, leasing or operation of its property or the conduct of its business
requires such qualifications.

          SECTION 4.02. Authorization; Enforceability. The Transactions are
within each Obligor's corporate powers and have been duly authorized by all
necessary corporate and, if required, by all necessary shareholder action. This
Agreement has been duly executed and delivered by each Obligor party hereto and
constitutes, and each of the other Credit Documents to which an Obligor is a
party when executed and delivered by such Obligor will constitute, a legal,
valid and binding obligation of such Obligor, enforceable against each Obligor
in accordance with its terms, except as such enforceability may be limited by
(a) bankruptcy, insolvency, reorganization, moratorium or similar laws of
general applicability affecting the enforcement of creditors' rights and (b) the
application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          SECTION 4.03. Governmental Approvals; No Conflicts. The execution,
delivery and performance of the Credit Documents (a) do not require any consent
or approval of, registration or filing with, or any other action by, any
Governmental Authority, except for (i) such as have been obtained or made and
are in full force and effect and (ii) filings and recordings in respect of the
Liens created pursuant to the Security Documents, (b) will not violate any
applicable law or regulation or the charter, by-laws or other organizational
documents of the Borrower or any of its Subsidiaries or any order of any
Governmental Authority applicable to the Borrower or any of its Subsidiaries,
(c) will not violate or result in a default under any indenture, mortgage, deed
of trust, credit agreement or loan agreement or any other material agreement,
contract or instrument binding upon the Borrower or any of its Subsidiaries or
assets, or give rise to a right thereunder to require any payment to be made by
any such Person and (d) except for Liens created pursuant to the Security
Documents, will not result in the creation or imposition of any Lien on any
asset of the Borrower or any of its Subsidiaries.

          SECTION 4.04. Financial Condition; No Material Adverse Change.

          (a) Financial Condition. The Borrower has heretofore furnished to the
Lenders its audited consolidated balance sheet and statements of income,
stockholders' equity and cash

                 Amended and Restated Revolving Credit Agreement

                                      -51-

flows as of and for the fiscal years ended December 31, 2002 reported on by
Ernst & Young LLP and its unaudited consolidated balance sheet and statements of
income and cash flows as of and for the six-month period ended June 30, 2003.
Such financial statements present fairly, in all material respects, the
financial position and results of operations and cash flows of the Borrower and
its Subsidiaries as of such dates and for such periods in accordance with GAAP
(subject, with respect to such financial statements as of and for such six-month
period ended June 30, 2003, to normal year-end audit adjustments and the absence
of footnotes). Neither the Borrower nor any of its Subsidiaries has, on the date
hereof, any material contingent liabilities, material liabilities for taxes,
long-term leases or unusual forward or long-term commitments, including any
interest rate or foreign currency swap or exchanged transactions, or any
unrealized or anticipated losses from any unfavorable commitments, which are not
reflected in such financial statements as required by GAAP.

          (b) No Material Adverse Change. Since the Petition Date, there has
been no development or event that has had or could reasonably be expected to
have a Material Adverse Effect (other than with respect to any change of the
type that customarily occurs following commencement of a proceeding under
chapter 11 of the Bankruptcy Code).

          SECTION 4.05. Properties.

          (a) Property Generally. Each of the Borrower and its Subsidiaries has
good title to, or valid leasehold interests in, all its real and personal
property material to its business, subject only to Liens permitted by Section
7.02 and except for minor defects in title that do not interfere with its
ability to conduct its business as currently conducted or to utilize such
properties for their intended purposes.

          (b) Intellectual Property. Each of the Borrower and its Subsidiaries
owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and
other intellectual property material to its business, and the use thereof by the
Borrower and its Subsidiaries does not infringe upon the rights of any other
Person, except for any such infringements that, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

          SECTION 4.06. Litigation. Except for the matters disclosed in Schedule
4.06, there are no actions, suits or proceedings by or before any arbitrator or
Governmental Authority now pending against or, to the knowledge of the Borrower,
threatened against or affecting the Borrower or any of its Subsidiaries (i) that
could reasonably be expected, either individually or in the aggregate, to have a
Material Adverse Effect or (ii) with respect to this Agreement or the
Transactions. Since the date of this Agreement, there has been no change in the
status of the matters disclosed in Schedule 4.06 that, either individually or in
the aggregate, could reasonably be expected to have, or materially increase the
likelihood of, a Material Adverse Effect.

          SECTION 4.07. Environmental Matters. Each of the Borrower and its
Subsidiaries has obtained all environmental, health and safety permits,
licenses, registrations and other authorizations required under all
Environmental Laws to carry on its business as now being or as proposed to be
conducted, except to the extent failure to have any such permit, license,
registration or authorization would not (either individually or in the
aggregate) have a Material Adverse Effect. Each of such permits, licenses,
registrations and authorizations is in full force

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -52-

and effect and each of the Borrower and its Subsidiaries is in compliance with
the terms and conditions thereof, and is also in compliance with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules and timetables contained in any applicable Environmental
Law or in any regulation, code, plan, order, decree, judgment, injunction
issued, entered, promulgated or approved thereunder, except to the extent
failure to comply therewith would not (either individually or in the aggregate)
have a Material Adverse Effect.

          In addition, except as disclosed in Schedule 4.07:

          (a) No Pending Environmental Matters. No written notice, notification,
     demand, request for information, citation, summons or order has been
     issued, no complaint has been filed, no penalty has been assessed and no
     investigation or review is pending or, to the best knowledge of the
     Borrower or any of its Subsidiaries, threatened by any governmental or
     other entity with respect to any alleged failure by the Borrower or any of
     its Subsidiaries to have any environmental, health or safety permit,
     license, registration or other authorization required under any
     Environmental Law in connection with the conduct of the business of the
     Borrower or any of its Subsidiaries or with respect to any generation,
     treatment, storage, recycling, transportation, discharge or disposal, or
     any Release of any Hazardous Materials generated by the Borrower or any of
     its Subsidiaries.

          (b) No Permits Required; Certain Specific Representations. Neither the
     Borrower nor any of its Subsidiaries owns, operates or leases a treatment,
     storage or disposal facility requiring a permit under the Resource
     Conservation and Recovery Act of 1976, as amended, or under any comparable
     state or local statute; and

               (i) no polychlorinated biphenyls (PCB's) are or have been present
          at or above regulated levels at any site or facility now or previously

               (ii) no regulated asbestos or asbestos-containing materials is or

          operated or leased by the Borrower or any of its Subsidiaries;

               (iii) there are no underground storage tanks or surface
          impoundments for Hazardous Materials, active or abandoned, at any site
          or facility now or, to the best knowledge of the Borrower or any of
          its Subsidiaries, previously owned, operated or leased by the Borrower
          or any of its Subsidiaries;

               (iv) no Hazardous Materials have been Released at, on or under
          any site or facility now or previously owned, operated or leased by
          the Borrower or any of its Subsidiaries in a reportable quantity

               (v) no Hazardous Materials have been otherwise Released at, on or

                                      -53-

          or any of its Subsidiaries that would (either individually or in the
          aggregate) have a Material Adverse Effect.

          (c) No Hazardous Material Transported to NPL Sites. Neither the
     Borrower nor any of its Subsidiaries has transported or arranged for the
     transportation of any Hazardous Material in amounts or quantities other
     than those not reasonably likely to have a Material Adverse Effect to any
     location that is listed on the National Priorities List ("NPL") under the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, as amended ("CERCLA"), listed for possible inclusion on the NPL by
     the Environmental Protection Agency in the Comprehensive Environmental
     Response and Liability Information System, as provided for by 40 C.F.R. ss.
     300.5 ("CERCLIS"), or on any similar state or local list or that is the
     subject of Federal, state or local enforcement actions or other
     investigations that may lead to Environmental Claims against the Borrower
     or any of its Subsidiaries.

          (d) No Notifications or Listings. No oral or written notification of a
     Release of a Hazardous Material has been filed by or on behalf of the
     Borrower or any of its Subsidiaries and no site or facility now or
     previously owned, operated or leased by the Borrower or any of its
     Subsidiaries is listed or proposed for listing on the NPL, CERCLIS or any
     similar state list of sites requiring investigation or clean-up.

          (e) No Liens or Restrictions. No Liens have arisen under or pursuant
     to any Environmental Laws on any site or facility owned, operated or leased
     by the Borrower or any of its Subsidiaries, and no government action has
     been taken or is in process that could subject any such site or facility to
     such Liens and neither the Borrower nor any of its Subsidiaries would be
     required to place any notice or restriction relating to the presence of
     Hazardous Materials at any site or facility owned by it in any deed to the
     real property on which such site or facility is located.

          (f) Full Disclosure. All environmental investigations, studies,
     audits, tests, reviews or other analyses conducted by or that are in the
     possession of the Borrower or any of its Subsidiaries in relation to facts,
     circumstances or conditions at or affecting any site or facility now or
     previously owned, operated or leased by the Borrower or any of its
     Subsidiaries and that could have a Material Adverse Effect have been made
     available to the Lenders.

Borrower and its Subsidiaries is in compliance with all Requirements of Law
applicable to it or its property and all indentures, agreements and other
instruments binding upon it or its property, except where the failure to do so,

have a Material Adverse Effect.

Borrower nor any of its Subsidiaries is (a) an "investment company" as defined
in, or subject to regulation under, the Investment Company Act of 1940 or (b) a

          SECTION 4.10. Taxes. Each of the Borrower and its Subsidiaries has
timely filed or caused to be filed all Tax returns and reports required to have
been filed and has paid or caused to be paid all Taxes required to have been
paid by it, except (a) Taxes that are being contested in good faith by
appropriate proceedings and for which such Person has set aside on its books
adequate reserves or (b) to the extent that the failure to do so could not
reasonably be expected to have a Material Adverse Effect.

          SECTION 4.11. ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
have a Material Adverse Effect. The present value of all accumulated benefit
obligations under each Plan (based on the assumptions used for purposes of
Statement of Financial Accounting Standards No. 87) did not, as of the date of
the most recent annual financial statements reflecting such amounts, exceed the
fair market value of the assets of such Plan by more than $15,000,000.

          SECTION 4.12. Disclosure. The Borrower has disclosed to the Lenders
all agreements, instruments and corporate or other restrictions to which it or
any of its Subsidiaries is subject, and all other matters known to it, that,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect. None of the reports, financial statements, certificates
or other information furnished by or on behalf of the Obligors to the Lenders in
connection with the negotiation of this Agreement and the other Credit Documents
or delivered hereunder or thereunder (as modified or supplemented by other
information so furnished), when taken as a whole, contains any material
misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided that, with respect to projected financial
information, the Borrower represents only that such projected financial
information was prepared in good faith based upon assumptions believed to be
reasonable at the time, it being recognized by the Lenders that such projected
financial information include forward-looking statements that by their very
nature are subject to significant risks, uncertainties and contingencies, many
of which are beyond the control of the Borrower and its Subsidiaries and that
actual results may differ, perhaps materially, from those expressed or implied
in such forward-looking statements. There is no fact known to the Borrower or
any of its Subsidiaries that could reasonably be expected to have a Material
Adverse Effect that has not been disclosed herein, in the other Credit Documents
or in a report, financial statement, exhibit, schedule, disclosure letter or
other writing furnished to the Lenders for use in connection with the
Transactions.

          SECTION 4.13. Use of Credit. Neither the Borrower nor any of its
Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose, whether immediate, incidental
or ultimate, of buying or carrying Margin Stock, and no part of the proceeds of
any extension of credit hereunder will be used to buy or carry any Margin Stock.

          SECTION 4.14. Debt Agreements and Liens.

and the Term Loan Agreement) and covering any property of the Borrower or any of
its Subsidiaries, and the aggregate Indebtedness secured (or that may be
secured) by each such Lien and the property covered by each such Lien is

Effective Date) (x) each of the Borrower and its Subsidiaries owns, or will own,
free and clear of Liens (other than Liens created pursuant to the Security

interests in each Person shown to be held by it in Schedule 4.15(a), (y) all of
the issued and outstanding Capital Stock of each such Person organized as a
corporation is validly issued, fully paid and nonassessable and (z) there are no

of the date hereof, of all of the real property interests held by the Borrower
and its Subsidiaries, indicating in each case whether the respective property is
owned or leased, the identity of the owner or (in the case of any leased
property) the lessor and lessee thereof, and the location of the respective
property, and designating the properties that will subject to a Mortgage as of
the Effective Date.

          SECTION 4.17. Labor Matters. Except as set forth in Schedule 4.17, (a)
on the date hereof neither the Borrower nor any of its Subsidiaries nor any of
their respective employees is subject to any collective bargaining agreement,

Borrower and its Subsidiaries have not been in violation of the Fair Labor
Standards Act or any other applicable law, regulation or order of any
Governmental Authority dealing with such matters that (individually or in the
aggregate) could reasonably be expected to have a Material Adverse Effect. All
payments due from the Borrower or any of its Subsidiaries on account of employee
health and welfare insurance that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect if not paid have been
paid or accrued as a liability on the books of the Borrower or the relevant
Subsidiary.

          SECTION 4.18. No Burdensome Restrictions. Neither the Borrower nor any
of its Subsidiaries is a party to any agreement or other contractual arrangement
imposing burdensome requirements upon the Borrower or any of its Subsidiaries
that, taking into account the benefits of such agreement or other arrangement to
the Borrower or such Subsidiary, could reasonably be expected to have a Material
Adverse Effect.

          SECTION 4.19. Solvency. As of the Effective Date and after giving
effect to the Transactions contemplated hereby, (a) the aggregate value of all
properties of the Borrower and its Subsidiaries at their present fair saleable
value (i.e., the amount that may be realized within a reasonable time,
considered to be six months to one year, either through collection or sale at
the regular market value, conceiving the latter as the amount that could be
obtained for the property in question within such period by a capable and
diligent businessman from an interested buyer who is willing to purchase under
ordinary selling conditions, and determined on a going concern basis), exceeds

audit is requested following the occurrence and during the continuance of any

          SECTION 6.07. Compliance with Laws and Agreements. The Borrower will,
and will cause each of its Subsidiaries to, comply with (i) all applicable laws

except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

          SECTION 6.08. Use of Proceeds and Letters of Credit. The proceeds of
the Loans will be used only for working capital and other general corporate
purposes of the Borrower and its Subsidiaries in the ordinary course of
business. Neither the Borrower nor any of its Subsidiaries is engaged

credit hereunder will be used to buy or carry any Margin Stock.

          SECTION 6.09. Additional Guarantors; Additional Collateral; Ownership
of Subsidiaries

          (a) Subsidiary Guarantors. The Borrower will take such action, and
will cause each of its Subsidiaries to take such action, from time to time as
shall be necessary to ensure that all Subsidiaries of the Borrower are
"Subsidiary Guarantors" hereunder; provided that, notwithstanding anything
herein to the contrary, the following Subsidiaries shall not be required to be
or become Subsidiary Guarantors hereunder or Obligors under any Security
Document (collectively, the "Excluded Subsidiaries"): (i) any Foreign
Subsidiary; and (ii) any Domestic Subsidiary held, directly or indirectly, by a
Foreign Subsidiary. Without limiting the foregoing, in the event that the
Borrower or any of its Subsidiaries shall form or acquire any new Subsidiary
(other than an Excluded Subsidiary) that shall constitute a Subsidiary
hereunder, the Borrower and its Subsidiaries will cause such new Subsidiary to
become a "Subsidiary Guarantor" hereunder and an "Obligor".

          (b) Additional Collateral. The Borrower will, and will cause each of
the other Obligors to, grant from time to time to the Collateral Agent for the
benefit of the Secured Parties security interests in all of the assets and
properties of the Borrower and other Obligors, now existing or hereafter
acquired, pursuant to the relevant Security Documents. All such security
interests and Liens shall be granted pursuant to documentation reasonably
satisfactory in form and substance to the Administrative Agent and shall
constitute valid and enforceable perfected security interests and Liens in favor
of the Collateral Agent superior to and prior to the rights of all third Persons
and subject to no other Liens except for Liens permitted under Section 7.02. The
Liens on such assets and properties and/or the security agreements or other
instruments related thereto shall have been duly recorded or filed in such
manner and in such places as are required by law to establish, perfect, preserve
and protect the Liens in favor of the Collateral Agent as required pursuant to
the relevant Security Documents and all taxes, fees and other charges payable in
connection therewith shall have been paid in full. The Borrower will, and

<PAGE>

                                      -66-

execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from
time to time such vouchers, invoices, schedules, confirmatory assignments,
conveyances, financing statements, transfer endorsements, powers of attorney,
certificates, real property surveys, reports, landlord waivers, bailee
agreements, control agreements and other assurances or instruments and take such
further steps relating to the Collateral covered by any of the Security
Documents as the Collateral Agent may reasonably require. Furthermore, the
Borrower will, and will cause the other Obligors to, deliver to the Collateral
Agent such opinions of counsel, title insurance and other related documents as
may be reasonably requested by the Administrative Agent to assure itself that
this Section has been complied with.

          Notwithstanding the foregoing, in the event the Borrower or any
Subsidiary that which is organized under the laws of a State, the United States
of America or the District of Columbia shall form or acquire directly a Foreign
Subsidiary, the Borrower will, and will cause such Subsidiary to pledge the
Capital Stock of such Foreign Subsidiary in favor of the Collateral Agent
pursuant to the relevant Security Document in form and substance reasonably
satisfactory to the Administrative Agent, provided that such pledge of Capital
Stock of a Foreign Subsidiary shall be limited to (i) 65% of the voting Capital
Stock of such Foreign Subsidiary having ordinary voting power for the election
of the board of directors of such Subsidiary and (ii) 100% of all other Capital
Stock of such Foreign Subsidiary; and provided further that, notwithstanding the
foregoing, no portion of the Capital Stock of Chart Europe GmbH ("Chart Europe")
held by the Borrower and its Subsidiaries as of the Effective Date shall be
required to be pledged pursuant to this Agreement, provided that the Borrower
will cause Chart Europe to be liquidated on or prior to June 30, 2004 and, prior
to such liquidation, the Borrower will not, and will not permit any of its
Subsidiaries to, engage in any transaction with Chart Europe other than those
directly related to the consummation of such liquidation (and, in any event,
will not make any Investment in, or transfer any property to, Chart Europe after
the Effective Date).

          Notwithstanding the foregoing, as of the Effective Date the Borrower
will, and will cause the other Obligors to, execute and deliver the Mortgages
with respect to such real property interests of the Borrower and the other
Obligors as are designated to be so mortgaged in Schedule 4.16. From time to
time thereafter the Borrower will, and will cause each other Obligor to, notify
the Administrative Agent within 30 days of the acquisition of any additional
real property interests (whether a fee or leasehold) and, thereafter upon the
request of the Required Lenders, grant a mortgage lien on such real property
pursuant to a Mortgage in form and substance reasonably satisfactory to the
Administrative Agent; provided that, in no event will the Borrower or any of its
Subsidiaries be required to take any action, other than using commercially
reasonable efforts, to obtain consents from third parties with respect to its
compliance with this paragraph. If the Administrative Agent or the Required
Lenders reasonably determine that they are required by law or regulation to have
appraisals prepared in respect of any real property of the Borrower and its
Subsidiaries constituting Collateral, the Borrower will, at its own expense,
provide to the Administrative Agent appraisals which satisfy the applicable
requirements of the Real Estate Appraisal Reform Amendments of the Financial
Institution Reform, Recovery and Enforcement Act of 1989, as amended, and which
shall otherwise be in form and substance reasonably satisfactory to the
Administrative Agent.

          (c) Further Assurances. The Borrower will, and will cause each of its
Subsidiaries to, take such action from time to time as shall reasonably be
requested by the Administrative Agent or Collateral Agent to effectuate the
purposes and objectives of this Agreement. Without limiting the generality of
the foregoing, the Borrower will, and will cause each other Obligor to, take
such action from time to time (including filing appropriate Uniform Commercial
Code financing statements and executing and delivering such assignments,
security agreements and other instruments) as shall be reasonably requested by
the Collateral Agent to create, in favor of the Collateral Agent, perfected
security interests and Liens in the Collateral purported to be granted as
collateral security for its obligations hereunder and under the Credit
Documents, as required by the Security Documents. Without limiting the
foregoing, in the event that any Capital Stock shall be issued by any Subsidiary
(including, without limitation, any Subsidiary formed or acquired after the date
hereof), subject (in the case of any Foreign Subsidiary) to the limitation under
paragraph (b) of this Section, the respective Obligor agrees forthwith to
deliver to the Collateral Agent pursuant to the relevant Security Document the
certificates (if any) evidencing such Capital Stock owned by such Obligor,
accompanied by undated stock (or other) powers executed in blank and to take
such other action as the Collateral Agent shall request to perfect the security
interest created therein pursuant to the relevant Security Document.

          (d) Ownership of Subsidiaries. The Borrower will, and will cause each
of its Subsidiaries to, take such action from time to time as shall be necessary
to ensure that each of its Subsidiaries is a Wholly Owned Subsidiary; provided
that in the case of any Subsidiary that as of the Effective Date is not a Wholly
Owned Subsidiary (as set forth in Schedule 4.15(a)), the Borrower will, and will
cause each of its Subsidiaries to, own not less than the percentage of Capital
Stock of such Subsidiary owned by it as of the Effective Date.

          (e) Post-Effective Date Undertakings. The Borrower will, and will
cause its Subsidiaries, within 60 days after the Effective Date, to execute and
deliver a Foreign Subsidiary Pledge Agreement, or an amendment to an Existing
Foreign Subsidiary Pledge Agreement, in each case in form and substance
satisfactory to the Collateral Agent, between each Obligor that holds directly
the Capital Stock of a Foreign Subsidiary as of the Effective Date (other than
the Capital Stock of CHEL and Chart Europe) and the Collateral Agent (or any
sub-agent acting for, or any other Person designated by, the Collateral Agent)
pledging such Capital Stock (subject to the limitations in the second paragraph
of Section 6.09(b)), in each case together with (i) the certificates (if any)
representing such Capital Stock identified therein and undated stock (or other)
powers executed in blank and (ii) such other documents (including an opinion of
counsel approved by the Collateral Agent) and certificates as the Collateral
Agent or its counsel may reasonably request relating to such pledgor, the pledge
of such Capital Stock and all other legal matters relating to such Foreign
Subsidiary Pledge Agreement, all in form and substance reasonably satisfactory
to the Collateral Agent and its counsel. In addition, the respective pledgor of
such Capital Stock will take all other action as the Collateral Agent or its
counsel shall have requested in order to create, perfect and validate the
security interests created pursuant to each such Foreign Subsidiary Pledge
Agreement.

     amount of cash, together with the aggregate fair market value of property,
     loaned, advanced, contributed, transferred or otherwise invested that gives
     rise to such Investment minus (ii) the aggregate amount of dividends,
     distributions or other payments received in cash in respect of such
     Investment; the amount of an Investment shall not in any event be reduced
     by reason of any write-off of such Investment nor increased by any increase

engage in any other transactions with, any of its Affiliates, except:

          (a) transactions in the ordinary course of business and on terms and

     time in a comparable arm's-length transaction with a Person other than an
     Affiliate;

          (b) transactions between or among the Borrower and one or more Wholly

or imposes any condition upon (a) the ability of the Borrower or any Subsidiary
to create, incur or permit to exist any Lien upon any of its property or assets,
or (b) the ability of any Subsidiary to pay dividends or other distributions
with respect to any shares of its Capital Stock or to make or repay loans or
advances to the Borrower or any other Subsidiary or to guarantee Indebtedness of
the Borrower or any other Subsidiary; provided that:

          (i) the foregoing shall not apply to (w) restrictions and conditions
     imposed by law, (x) restrictions and conditions under the Credit Documents
     and the Term Loan Documents, (y) other restrictions and conditions existing
     on the date hereof identified on Schedule 7.07 (but shall apply to any
     extension or renewal of, or any amendment or modification expanding the
     scope of, any such restriction or condition) and (z) customary restrictions
     and conditions contained in agreements relating to the sale of a Subsidiary
     pending such sale, provided such restrictions and conditions apply only to
     the Subsidiary that is to be sold and such sale is permitted hereunder; and

          (ii) clause (a) of the foregoing shall not apply to (x) restrictions
     or conditions imposed by any agreement relating to secured Indebtedness
     permitted by this Agreement if such restrictions or conditions apply only

     provisions in leases and other contracts restricting the assignment
     thereof.

          SECTION 7.08. Operating Leases. The Borrower will not, and will not

          (e) Capital Expenditures. The Borrower will not, and will not permit
any of its Subsidiaries to, make any Capital Expenditures, except that during
any fiscal year of the Borrower set forth below, the Borrower and its
Subsidiaries may make Capital Expenditures so long as the aggregate amount of
all such Capital Expenditures does not exceed in any fiscal year of the Borrower

Expenditures permitted to be made by the Borrower and its Subsidiaries pursuant
to the table above in any fiscal year of the Borrower (before giving effect to
any increase in such permitted Capital Expenditure amount pursuant to this

may be carried forward and utilized to make Capital Expenditures in the
succeeding fiscal years, provided that no amounts expended in any fiscal year
shall exceed 150% of the amount set forth above for such fiscal year.

          In addition to the foregoing, the Borrower and its Subsidiaries may
make Capital Expenditures (x) with the amount of (i) Net Cash Proceeds received

restore any properties or assets in respect of which such Net Cash Proceeds were
paid or (ii) Net Cash Proceeds received by the Borrower or any of its
Subsidiaries from any Equity Issuance or (y) as tenant under any lease in
respect of leasehold improvements to the extent such expenditures are reimbursed
by the landlord under the related lease or sale leaseback transaction, but in
the case of clause (i) above only to the extent that such Net Cash Proceeds are
not otherwise required to be applied to a prepayment pursuant to Section 2.09(b)
or the corresponding provision of the Term Loan Agreement.

          SECTION 7.10. Modifications of Certain Documents. The Borrower will
not, and will not permit any of its Subsidiaries to, consent or otherwise agree
to any modification, supplement or waiver of any of the provisions of any
agreement, instrument or other document evidencing or relating to (i) the
charter, by-laws or other organizational documents of the Borrower or any of the
Subsidiary Guarantors (other than those modifications to the charter, by-laws or
other organizational documents of the Borrower or any of the Subsidiary
Guarantors occurring upon or simultaneously with the consummation of the
Reorganization Plan which have

instrument providing for or evidencing subordinated Indebtedness of the Borrower
or any of its Subsidiaries, in each case with respect to clause (i) or (ii)

to whom funds have been or are to be advanced by such Person on the security of
such property or rental obligations of the Borrower or any of its Subsidiaries,
other than such transactions not exceeding an aggregate sale price of
$5,000,000.

          SECTION 7.12. Restrictions on CHEL. The Borrower will not, and will
not permit any of its Subsidiaries (other than CHEL) to, engage in any

of any property or the making of any loan or other Investment) with CHEL, and
the Borrower will not permit CHEL to engage in any transaction, except any
transaction incidental to the administration proceeding in respect of CHEL.

     appointment of a receiver, trustee, custodian, sequestrator, conservator or
     similar official for the Borrower or any of its Subsidiaries (other than

     such case, such proceeding or petition shall continue undismissed for a
     period of 60 or more days or an order or decree approving or ordering any
     of the foregoing shall be entered;

          (i) the Borrower or any of its Subsidiaries (other than CHEL and Chart

     of a receiver, trustee, custodian, sequestrator, conservator or similar
     official for the Borrower or any of its Subsidiaries (other than CHEL and

     such proceeding, (v) make a general assignment for the benefit of creditors
     or (vi) take any action for the purpose of effecting any of the foregoing;

          (j) the Borrower or any of its Subsidiaries (other than CHEL and Chart
     Europe) shall admit in writing its inability or fail generally to pay its
     debts as they become due;

          (k) one or more judgments for the payment of money (not covered by
     insurance to the extent the relevant insurer has acknowledged coverage
     thereunder) in an aggregate amount in excess of $5,000,000, shall be
     rendered against the Borrower or any of its Subsidiaries or any combination
     thereof, and such judgments either shall be final and nonappealable or
     shall not be vacated, discharged, stayed or bonded pending appeal for any
     period of 30 consecutive days;

          (l) an ERISA Event shall have occurred that, in the opinion of the
     Required Lenders, when taken together with all other ERISA Events that have
     occurred, could reasonably be expected to result in liability to the

          (m) there shall have been asserted against the Borrower or any of its
     Subsidiaries an Environmental Claim that, in the judgment of the Required
     Lenders, is reasonably likely to be determined adversely to the Borrower or
     any of its Subsidiaries, and the amount thereof (either individually or in
     the aggregate) is reasonably likely to result liability of the Borrower and
     its Subsidiaries in an aggregate amount exceeding $3,000,000 (insofar as
     such amount is payable by the Borrower or any of its Subsidiaries but after
     deducting any portion thereof that is reasonably expected to be paid by
     other creditworthy Persons jointly and severally liable therefor);

          (n) a Change in Control shall occur;

          (o) any Subsidiary of the Borrower (other than CHEL and Chart Europe)

     Agreement), or the validity or enforceability thereof shall be contested by
     any Subsidiary Guarantor; or

          (q) other than in connection with any termination of any Lien, the
     Liens created by the Security Documents shall at any time not constitute a
     valid and perfected Lien on the collateral intended to be covered thereby
     (to the extent perfection by filing, registration, recordation or
     possession is required herein or therein) in favor of the Collateral Agent,
     free and clear of all other Liens (other than Liens permitted under Section
     7.02 or under the respective Security Documents), or, except for expiration
     or termination in accordance with its terms, any of the Security Documents
     shall for

     whatever reason be terminated or cease to be in full force and effect, or
     the enforceability thereof shall be contested in writing by any Obligor;

then, and in every such event (other than an event with respect to any Obligor
described in clause (h) or (i) of this Article) and at any time thereafter
during the continuance of such event, the Administrative Agent shall, at the
request of or with the consent of the Required Lenders, by notice to the
Borrower, take either or both of the following actions, at the same or different
times: (i) terminate the Commitments, and thereupon the Commitments shall
terminate immediately, and (ii) declare the Loans then outstanding to be due and
payable in whole (or in part, in which case any principal not so declared to be
due and payable may thereafter be declared to be due and payable), and thereupon
the principal of the Loans so declared to be due and payable, together with
accrued interest thereon and all fees and other obligations of the Obligors
accrued hereunder, shall become due and payable immediately, without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by each Obligor; provided that in case of any event with respect
to any Obligor described in clause (h) or (i) of this Article, the Commitments
shall automatically terminate and the principal of the Loans then outstanding,
together with accrued interest thereon and all fees and other obligations of the
Obligors accrued hereunder, shall automatically become due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by each Obligor.

          Anything herein to the contrary notwithstanding, it is understood that
(i) no Lender has the right to individually terminate its Commitments (such
right of termination residing with the Administrative Agent as provided above),
(ii) no Lender has the right to declare its Loans due and payable (such right to
declare the Loans due and payable residing with the Administrative Agent as
provided above, subject to the proviso set forth above in the case of an Event
of Default under clause (h) or (i) of this Article), and (iii) no Lender has the
right to exercise any remedies under any Security Document (such right to
exercise remedies residing with the Collateral Agent as provided therein).

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

          Each of the Lenders and the Issuing Lenders hereby irrevocably
appoints the Administrative Agent as its agent hereunder and under the other
Credit Documents to which it is a party and authorizes the Administrative Agent
to take such actions on its behalf and to exercise such powers as are delegated
to the Administrative Agent by the terms hereof or thereof, together with such
actions and powers as are reasonably incidental thereto.

          The Person serving as the Administrative Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and
may exercise the same as though it were not the Administrative Agent, and such
Person and its Affiliates may accept deposits from, lend money to and generally
engage in any kind of business with the Borrower or any Subsidiary or other
Affiliate thereof as if it were not the Administrative Agent hereunder.

          The Administrative Agent shall not have any duties or obligations
except those expressly set forth herein and in the other Credit Documents.
Without limiting the generality of

                Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -82-

the foregoing, (a) the Administrative Agent shall not be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing, (b) the Administrative Agent shall not have any duty to take
any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby or by the other
Credit Documents that the Administrative Agent is required to exercise in
writing by the Required Lenders, and (c) except as expressly set forth herein
and in the other Credit Documents, the Administrative Agent shall not have any
duty to disclose, and shall not be liable for the failure to disclose, any
information relating to the Borrower or any of its Subsidiaries that is
communicated to or obtained by the bank serving as Administrative Agent or any
of its Affiliates in any capacity. The Administrative Agent shall not be liable
for any action taken or not taken by it with the consent or at the request of
the Required Lenders or in the absence of its own gross negligence or willful
misconduct. The Administrative Agent shall be deemed not to have knowledge of
any Default unless and until written notice thereof is given to the
Administrative Agent by the Borrower or a Lender, and the Administrative Agent
shall not be responsible for or have any duty to ascertain or inquire into (i)
any statement, warranty or representation made in or in connection with this
Agreement or any other Credit Document, (ii) the contents of any certificate,
report or other document delivered hereunder or thereunder or in connection
herewith or therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein or therein,
(iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Credit Document or any other agreement, instrument or
document, or (v) the satisfaction of any condition set forth in Article V or
elsewhere herein or therein, other than to confirm receipt of items expressly
required to be delivered to the Administrative Agent.

          The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon. The Administrative Agent may consult with legal counsel (who
may be counsel for an Obligor), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

          The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent (including, without limitation, under any
Security Document). The Administrative Agent and any such sub-agent may perform
any and all its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent. Each Lender by its
execution and delivery of this Agreement agrees, as contemplated by Section 4.04
of the Security Agreement, that, in the event it shall hold any Permitted
Investments of any Obligor referred to therein, such Permitted Investments shall
be held in the name and under the control of such Lender, and such Lender shall
hold such Permitted Investments as a collateral

                Amended and Restated Revolving Credit Agreement

                                      -83-

sub-agent for the Administrative Agent thereunder. Each Obligor by its execution
and delivery of this Agreement hereby consents to the foregoing.

          The Administrative Agent may resign at any time by notifying the
Lenders, the Issuing Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right, in consultation with the Borrower, to
appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent's resignation shall nonetheless become effective
and (i) the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder and (ii) the Required Lenders shall perform the duties
of the Administrative Agent (and all payments and communications provided to be
made by, to or through the Administrative Agent shall instead be made by or to
each Lender directly) until such time as the Required Lenders appoint a
successor agent as provided for above in this paragraph. Upon the acceptance of
its appointment as Administrative Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring (or retired) Administrative Agent and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder (if not already discharged therefrom as provided above in this
paragraph). The fees payable by the Borrower to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the Administrative Agent's
resignation hereunder, the provisions of this Article and Section 10.03 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Administrative Agent.

          Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Credit Document or any related agreement or any document furnished
hereunder or thereunder.

          Notwithstanding anything herein to the contrary, the Sole Lead
Arranger and Bookrunner named on the cover page of this Agreement shall not have
any duties or liabilities under this Agreement or the other Credit Documents.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto (or, in the case
of any such change by a Lender, by notice to the Borrower and the Administrative
Agent). All notices and other communications given to any party hereto in
accordance with the provisions of this Agreement shall be deemed to have been
given on the date of receipt.

          SECTION 10.02. Waivers; Amendments.

          (a) No Deemed Waivers; Remedies Cumulative. No failure or delay by the
Administrative Agent, any Issuing Lender or any Lender in exercising any right
or power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent, the Issuing Lenders and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by any Obligor therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of

                Amended and Restated Revolving Credit Agreement

<PAGE>
                                      -85-

this Section, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the
generality of the foregoing, the making of a Loan or issuance of a Letter of
Credit shall not be construed as a waiver of any Default, regardless of whether
the Administrative Agent, any Lender or any Issuing Lender may have had notice
or knowledge of such Default at the time.

          (b) Amendments to this Agreement. Neither this Agreement nor any
provision hereof may be waived, amended or modified except pursuant to an
agreement or agreements in writing entered into by the Borrower, the Subsidiary
Guarantors and the Required Lenders or by the Borrower, the Subsidiary
Guarantors and the Administrative Agent with the consent of the Required
Lenders; provided that no such agreement shall:

          (i) increase any Commitment of any Lender without the written consent
     of such Lender;

          (ii) reduce or forgive the principal amount of any Loan or LC
     Disbursement or reduce the rate of interest thereon, or reduce or forgive
     any fees payable hereunder, without the written consent of each Lender
     directly affected thereby;

          (iii) postpone the date of any regularly scheduled payment of
     principal of any Loan or LC Disbursement, or any interest thereon, or any
     fees payable hereunder, or reduce the amount of, waive or excuse any such
     payment, or postpone the scheduled date of expiration of any Commitment,
     without the written consent of each Lender directly affected thereby;

          (iv) alter the pro rata treatment provisions of Sections 2.09(b)(vii)
     or 2.16(c), without the written consent of each Lender;

          (v) change any of the provisions of this Section or reduce the
     percentage in the definition of "Required Lenders" or any other provision
     hereof specifying the number or percentage of Lenders required to waive,
     amend or modify any rights hereunder or make any determination or grant any
     consent hereunder, without the written consent of each Lender; and

          (vi) subject to paragraph (d) below, release any Subsidiary Guarantor
     from any of its guarantee obligations under the Credit Document, without
     the written consent of each Lender;

and provided further that (x) no such agreement shall amend, modify or otherwise
affect the rights or duties of the Administrative Agent or any Issuing Lender
hereunder without the prior written consent of the Administrative Agent or the
affected Issuing Lender, as the case may be, and (y) that any modification or
supplement of Article III shall require the consent of each Guarantor.

          (c) Amendments to Other Credit Documents. Except as otherwise provided
in Section 10.02(b) with respect to this Agreement and subject to Section
10.02(d), the Administrative Agent may, with the prior consent of the Required
Lenders (but not otherwise),

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -86-

consent to any modification, supplement or waiver under any of the Credit
Documents to which it is a party, provided that, without the prior consent of
each Lender, the Administrative Agent shall not, and shall not agree or consent
to any modification, supplement or waiver under any such Credit Documents to
(except as provided therein), (i) release all or substantially all of the
Collateral or otherwise terminate the Liens with respect thereto or (ii) alter
the relative priorities of the obligations entitled to the benefits of the Liens
created under the Security Documents; provided that no such agreement shall
amend, modify or otherwise affect the rights and duties of the Administrative
Agent or the Collateral Agent thereunder without the prior written consent of
the Administrative Agent or the Collateral Agent, as the case may be.

          (d) Certain Releases. Notwithstanding anything herein or in any other
Credit Document to the contrary, upon the occurrence of any Disposition of any
Collateral (including the Capital Stock of any Subsidiary) that is permitted
hereunder or consented to by the Required Lenders or any other transaction or
event permitted or consented to by the Required Lenders hereunder that results
in any Subsidiary ceasing to be a Subsidiary of the Borrower, each of the
Administrative Agent and the Collateral Agent, as applicable, is hereby
authorized to release, without the prior consent of any Lender and at the
request of the Borrower, any Guarantee of such Subsidiary under the relevant
Credit Document or any such Collateral and/or the Liens on any such Collateral
under the relevant Credit Document. Each of the Administrative Agent and the
Collateral Agent shall take any action reasonably requested by the Borrower (at
the Borrower's sole cost and expense) to effect any such release.

          SECTION 10.03. Expenses; Indemnity; Damage Waiver.

          (a) Costs and Expenses. The Borrower shall pay (i) all reasonable
out-of-pocket expenses incurred by the Administrative Agent and its Affiliates,
including the reasonable fees, charges and disbursements of counsel for the
Administrative Agent, in connection with the syndication of the credit
facilities provided for herein, the preparation and administration of this
Agreement and the other Credit Documents or any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable
out-of-pocket expenses incurred by each Issuing Lender in connection with the
issuance, amendment, renewal or extension, as applicable, of any Letter of
Credit or any demand for payment thereunder, (iii) all out-of-pocket expenses
incurred by the Administrative Agent, any Issuing Lender or any Lender,
including the reasonable fees, charges and disbursements of counsel for the
Administrative Agent and the Collateral Agent and one counsel for the Lenders
(as selected by the Required Lenders), in connection with the enforcement or
protection of its rights in connection with this Agreement and the other Credit
Documents, including its rights under this Section, or in connection with the
Loans made or Letters of Credit issued hereunder, including in connection with
any workout, restructuring or negotiations in respect thereof or in connection
with the bankruptcy, insolvency or reorganization with respect to any Obligor,
and (iv) all out-of-pocket costs, expenses, taxes, assessments and other charges
incurred in connection with any filing, registration, recording or perfection of
any security interest contemplated by any Security Document or any other
document referred to therein.

          (b) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent, each Issuing Lender and each Lender, and each Related
Party of any of

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -87-

the foregoing Persons (each such Person being called an "Indemnitee") against,
and to hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including the fees, charges and disbursements
of any counsel for any Indemnitee, incurred by or asserted against any
Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of this Agreement or any agreement or instrument
contemplated hereby, the performance by the parties hereto of their respective
obligations hereunder or the consummation of the Transactions or any other
transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use
of the proceeds therefrom (including any refusal by the relevant Issuing Lender
to honor a demand for payment under a Letter of Credit if the documents
presented in connection with such demand do not strictly comply with the terms
of such Letter of Credit), (iii) any actual or alleged presence, release or
threatened release of Hazardous Materials relating to any property owned or
operated by the Borrower or any of its Subsidiaries, or any violation,
non-compliance with or liability under any Environmental Law related in any way
to the Borrower or any of its Subsidiaries or any of its respective property, or
(iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses are
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Indemnitee or any Related Party.

          (c) Reimbursement by Lenders. To the extent that the Borrower fails to
pay any amount required to be paid by it to the Administrative Agent or any
Issuing Lender under paragraph (a) or (b) of this Section, each Lender severally
agrees to pay to the Administrative Agent or such Issuing Lender, as the case
may be, such Lender's Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid
amount; provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent or such Issuing Lender in its capacity
as such, and provided further that such indemnity shall not be available to the
Administrative Agent or such Issuing Lender to the extent that such losses,
claims, damages, liabilities or related expenses are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of the Administrative Agent or such
Issuing Lender, as the case may be.

          (d) Waiver of Consequential Damages, Etc. To the extent permitted by
applicable law, no Obligor shall assert, and each Obligor hereby waives, any
claim against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement or any
agreement or instrument contemplated hereby, the Transactions, any Loan or
Letter of Credit or the use of the proceeds thereof.

          (e) Payments. All amounts due under this Section shall be payable

          SECTION 10.04. Successors and Assigns.

<PAGE>

                                      -88-

          (a) Assignments Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns permitted hereby (including any Affiliate of an Issuing
Lender that issues any Letter of Credit), except that (i) no Obligor may assign
or otherwise transfer any of its rights or obligations hereunder without the
prior written consent of each Lender (and any attempted assignment or transfer
by any Obligor without such consent shall be null and void) and (ii) any
assignment by a Lender of its rights or obligations hereunder shall comply with
the provisions of Section 10.04(b). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby (including any
Affiliate of an Issuing Lender that issues any Letter of Credit), Participants
(to the extent provided in paragraph (c) of this Section) and, to the extent
expressly contemplated hereby, the Related Parties of each of the Administrative
Agent, the Issuing Lenders and the Lenders) any legal or equitable right, remedy
or claim under or by reason of this Agreement.

          (b)(i) Assignments by Lenders. Subject to the conditions set forth in
paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it) with the prior
written consent (such consent not to be unreasonably withheld) of:

          (A) the Borrower, provided that no consent of the Borrower shall be
     required for an assignment to a Lender, an Affiliate of a Lender, an
     Approved Fund or, at any time during the continuance of an Event of
     Default, to any other Person (other than any Person that is a direct
     competitor of the Borrower or any of its Subsidiaries); and

          (B) the Administrative Agent, provided that no consent of the
     Administrative Agent shall be required for an assignment to an assignee
     that is a Lender immediately prior to giving effect to such assignment.

          (ii) Assignments shall be subject to the following additional
     conditions:

          (A) except in the case of an assignment to a Lender or an Affiliate of
     a Lender or an assignment of the entire remaining amount of the assigning
     Lender's Commitment or Loans, the amount of the Commitment or Loans of the
     assigning Lender subject to each such assignment (determined as of the date
     the Assignment and Assumption with respect to such assignment is delivered
     to the Administrative Agent) shall not be less than $5,000,000 unless each
     of the Borrower and the Administrative Agent otherwise consent, provided
     that no such consent of the Borrower shall be required if an Event of
     Default has occurred and is continuing;

          (B) each partial assignment shall be made as an assignment of a
     proportionate part of all the assigning Lender's rights and obligations
     under this Agreement;

          (C) the parties to each assignment shall execute and deliver to the
     Administrative Agent an Assignment and Assumption, together with a
     processing and recordation fee of $3,500; and

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -89-

          (D) the assignee, if it shall not be a Lender, shall deliver to the
     Administrative Agent an Administrative Questionnaire.

          (iii) Subject to acceptance and recording thereof pursuant to
paragraph (b)(iv) of this Section, from and after the effective date specified
in each Assignment and Assumption the assignee thereunder shall be a party
hereto and, to the extent of the interest assigned by such Assignment and
Assumption, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Assumption, be released from its obligations
under this Agreement (and, in the case of an Assignment and Assumption covering
all of the assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.13, 2.14, 2.15 and 10.03). Any assignment or transfer by
a Lender of rights or obligations under this Agreement that does not comply with
this Section 10.04 shall be treated for purposes of this Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with
paragraph (c) of this Section.

          (c) Maintenance of Register by the Administrative Agent. The
Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices in New York City a copy of each Assignment and
Assumption delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Commitment of, and principal amount of the
Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof
from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Borrower, the Agents, the Issuing Lenders and the Lenders
may treat each Person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Collateral Agent, any Issuing Lender and any
Lender, at any reasonable time and from time to time upon reasonable prior
notice.

          (d) Effectiveness of Assignments. Upon its receipt of a duly completed
Assignment and Assumption executed by an assigning Lender and an assignee, the
assignee's completed Administrative Questionnaire (unless the assignee shall
already be a Lender hereunder), the processing and recordation fee referred to
in paragraph (b) of this Section and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept
such Assignment and Assumption and record the information contained therein in
the Register. No assignment shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this paragraph.

          (e) Participations. Any Lender may, without the consent of the
Borrower, the Administrative Agent or any Issuing Lender, sell participations to
one or more banks or other entities (a "Participant") in all or a portion of
such Lender's rights and obligations under this Agreement and the other Credit
Documents (including all or a portion of its Commitment and the Loans owing to
it); provided that (A) such Lender's obligations under this Agreement and the
other Credit Documents shall remain unchanged, (B) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations and (C) the Borrower, the Agents, the Issuing Lenders and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement and

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -90-

the other Credit Documents. Any agreement or instrument pursuant to which a
Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and other Credit Documents and to
approve any amendment, modification or waiver of any provision of this Agreement
or any other Credit Document; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, modification or waiver described in the first proviso to
Section 10.02(b) that directly affects such Participant. Subject to paragraph
(c)(ii) of this Section, the Borrower agrees that each Participant shall be
entitled to the benefits of Sections 2.13 and 2.15 to the same extent as if it
were a Lender and had acquired its interest by assignment pursuant to paragraph
(b) of this Section. To the extent permitted by law, each Participant also shall
be entitled to the benefits of Section 10.08 as though it were a Lender,
provided such Participant agrees to be subject to Section 2.16(d) as though it
were a Lender.

          (f) Limitations on Rights of Participants. A Participant shall not be
entitled to receive any greater payment under Section 2.13, 2.14 or 2.15 than
the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to
such Participant is made with the Borrower's prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 2.15 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the
benefit of the Borrower, to comply with Section 2.15(e) as though it were a
Lender.

          (g) Certain Pledges. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to
secure obligations of such Lender, including any such pledge or assignment to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

          SECTION 10.05. Survival. All covenants, agreements, representations
and warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent, any Issuing Lender or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any
Letter of Credit is outstanding and so long as the Commitments have not expired
or terminated. The provisions of Sections 2.13, 2.14, 2.15, 3.03 and 10.03 and
Article IX shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof.

          SECTION 10.06. Counterparts; Integration. This Agreement may be
executed in counterparts (and by different parties hereto on different
counterparts), each of which shall


                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -91-

constitute an original, but all of which when taken together shall constitute a
single contract. This Agreement and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract
between and among the parties relating to the subject matter hereof and
supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Delivery of an executed counterpart of a
signature page to this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement.

          SECTION 10.07. Severability. Any provision of this Agreement held to
be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          SECTION 10.08. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and each Issuing Lender is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final, but excluding payroll and trust accounts) at any
time held and other indebtedness at any time owing by such Lender to or for the
credit or the account of any Obligor against any and all of the then due and
owing obligations of any Obligor, or of any other Subsidiary of the Borrower
that is an account party with respect to any Letter of Credit, under the Credit
Documents held by such Lender or such Issuing Lender or (with the consent of the
Required Lenders) any and all other obligations (which may be unmatured) of any
Obligor under the Credit Documents held by such Lender or such Issuing Lender,
irrespective of whether or not such Lender or such Issuing Lender shall have
made any demand thereunder. The rights of each Lender and each Issuing Lender
under this Section are in addition to other rights and remedies (including other
rights of setoff) which such Lender or such Issuing Lender may have.

          SECTION 10.09. Governing Law; Jurisdiction; Etc.

          (a) Governing Law. This Agreement shall be construed in accordance
with and governed by the law of the State of New York.

          (b) Submission to Jurisdiction. Each Obligor hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State court or, to the
extent permitted by law, in such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent, any Issuing Lender or any Lender may
otherwise have to bring any action

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -92-

or proceeding relating to this Agreement against any Obligor or its properties
in the courts of any jurisdiction.

          (c) Waiver of Venue. Each Obligor hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement in
any court referred to in paragraph (b) of this Section. Each of the parties
hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

          (d) Service of Process. Each party to this Agreement irrevocably
consents to service of process in the manner provided for notices in Section
10.01. Nothing in this Agreement will affect the right of any party to this
Agreement to serve process in any other manner permitted by law.

          SECTION 10.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

          SECTION 10.11. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

          SECTION 10.12. Treatment of Certain Information; Confidentiality.

          (a) Treatment of Certain Information. The Borrower acknowledges that
from time to time financial advisory, investment banking and other services may
be offered or provided to the Borrower or one or more of its Subsidiaries (in
connection with this Agreement or otherwise) by any Lender or by one or more
subsidiaries or affiliates of such Lender and the Borrower hereby authorizes
each Lender to share any information delivered to such Lender by the Borrower
and its Subsidiaries pursuant to this Agreement, or in connection with the
decision of such Lender to enter into this Agreement, to any such subsidiary or
affiliate, it being understood that any such subsidiary or affiliate receiving
such information shall be bound by the provisions of paragraph (b) of this
Section as if it were a Lender hereunder. Such authorization shall survive the
repayment of the Loans, the expiration or termination of the Letters of Credit
and the Commitments or the termination of this Agreement or any provision
hereof.

<PAGE>

                                      -93-

          (b) Confidentiality. Each of the Administrative Agent, the Issuing
Lenders and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (i) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (ii) to the extent requested by any regulatory authority, (iii)
to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (iv) to any other party to this Agreement, (v) to any
direct or indirect contractual counterparty in swap agreements or such
contractual counterparty's professional advisor (so long as such contractual
counterparty or professional advisor to such contractual counterparty agrees to
be bound by the provisions of this Section), (vi) in connection with the
exercise of any remedies hereunder or under any other Credit Document or any
suit, action or proceeding relating to this Agreement or any other Credit
Document or the enforcement of rights hereunder or thereunder, (vii) subject to
an agreement containing provisions substantially the same as those of this
paragraph, to any assignee of or Participant in, or any prospective assignee of
or Participant in, any of its rights or obligations under this Agreement, (viii)
with the consent of the Borrower or (ix) to the extent such Information (A)
becomes publicly available other than as a result of a breach of this paragraph
or (B) becomes available to the Administrative Agent, any Issuing Lender or any
Lender on a nonconfidential basis (and not as a result of a breach of any
applicable confidentiality agreement known to the Administrative Agent, any
Issuing Lender and/or any Lender) from a source other than an Obligor. For the
purposes of this paragraph, "Information" means all information received from
any Obligor relating to any Obligor or its business, other than any such
information that is available to the Administrative Agent, any Issuing Lender or
any Lender on a nonconfidential basis prior to disclosure by an Obligor. Any
Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so
if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information. Notwithstanding the foregoing, the Administrative
Agent, the Lenders and the Obligors (and each of their respective employees,
representatives or other agents) may disclose to any and all persons, without
limitation of any kind, the U.S. tax treatment and U.S. tax structure of the
transactions contemplated by this Agreement and all materials of any kind
(including opinions or other tax analyses) that are provided to such person
relating to such tax treatment or tax structure, other than any information for
which nondisclosure is reasonably necessary in order to comply with applicable
securities laws, and except that, with respect to any document or similar item
that in either case contains information concerning the U.S. tax treatment or
U.S. tax structure of such transactions as well as other information, this
paragraph shall only apply to such portions of the document or similar item that
relate to such tax treatment or tax structure.

          SECTION 10.13. Judgment Currency. This is an international loan
transaction in which the specification of Dollars or any Foreign Currency, as
the case may be (the "Specified Currency"), and payment in New York City or the
country of the Specified Currency, as the case may be (the "Specified Place"),
is of the essence, and the Specified Currency shall be the currency of account
in all events relating to obligations denominated in the Specified Currency. The
payment obligations of the Borrower and the Subsidiary Guarantors under this
Agreement shall not be discharged or satisfied by an amount paid in another
currency or in another place, whether pursuant to a judgment or otherwise, to
the extent that the amount so paid on conversion

                 Amended and Restated Revolving Credit Agreement

<PAGE>

                                      -94-

to the Specified Currency and transfer to the Specified Place under normal
banking procedures does not yield the amount of the Specified Currency at the
Specified Place due hereunder. If for the purpose of obtaining judgment in any
court it is necessary to convert a sum due hereunder in the Specified Currency
into another currency (the "Second Currency"), the rate of exchange that shall
be applied shall be the rate at which in accordance with normal banking
procedures the Administrative Agent could purchase the Specified Currency with
the Second Currency on the Business Day next preceding the day on which such
judgment is rendered. The obligations of each of the Borrower and the Subsidiary
Guarantors in respect of any such sum due from it to the Administrative Agent,
any Issuing Lender or any Lender hereunder or under any other Credit Document
(in this Section called an "Entitled Person") shall, notwithstanding the rate of
exchange actually applied in rendering such judgment, be discharged only to the
extent that on the Business Day following receipt by such Entitled Person of any
sum adjudged to be due hereunder in the Second Currency such Entitled Person may
in accordance with normal banking procedures purchase and transfer to the
Specified Place the Specified Currency with the amount of the Second Currency so
adjudged to be due; and each of the Borrower and the Subsidiary Guarantors
hereby, as a separate obligation and notwithstanding any such judgment, agrees
to indemnify such Entitled Person against, and to pay such Entitled Person on
demand, in the Specified Currency, the amount (if any) by which the sum
originally due to such Entitled Person in the Specified Currency hereunder
exceeds the amount of the Specified Currency so purchased and transferred.

          SECTION 10.14. Termination of 1999 Credit Agreement. Each of the
parties bound hereby agrees that, as of the Effective Date, the 1999 Credit
Agreement, and all obligations of the parties thereunder (except to the extent
such obligations are restructured, continued and/or confirmed hereunder or under
the Term Loan Agreement), will be terminated automatically; provided that
nothing herein shall impair in any way the liability of CHEL with respect to the
CHEL Letters of Credit or the right of the CHEL Issuing Lender at any time to
retain any amounts received by it (whether prior to or after the Effective Date)
for the account of CHEL as cash collateral for CHEL's liability with respect to
the CHEL Letters of Credit or to transfer any such amounts to the Administrative
Agent, any Lender or any other CHEL Issuing Lender.
