demonstrate that the Issuing Agent has the power to act as attorney-in-fact for
such Lender to execute and deliver such Several Letter of Credit.

          (d) Each Lender represents and warrants that each Several Letter of
Credit constitutes a legal, valid and binding obligation of such Lender
enforceable in accordance with its terms, provided that the enforceability
thereof is subject to general principles of equity and to bankruptcy, insolvency
and similar laws affecting the enforcement of creditors' rights generally.

          SECTION 2.02. Fronted Letters of Credit. (a) Subject to and upon the
terms and conditions set forth herein, each Account Party may request that any
Fronting Lender at any time and from time to time on or after the Effective Date
and prior to the Commitment

                                       22

<PAGE>

Expiration Date issue for its own account a letter of credit denominated in
Dollars for the account of such Account Party and in support of, on a standby
basis, Letter of Credit Supportable Obligations of such Account Party to any
other Person, and subject to and upon the terms and conditions herein set forth,
each Fronting Lender agrees to issue at any time and from time to time on or
after the Effective Date and prior to the Commitment Expiration Date one or more
irrevocable standby letters of credit in such form as may be approved by such
Fronting Lender, which approval shall not be unreasonably withheld or delayed
(each such letter of credit, a "Fronted Letter of Credit" and, collectively, the
"Fronted Letters of Credit"). Subject to the terms and conditions hereof and any
other instruments and documents contemplated hereby, it is the intent of the
parties hereto that all Letters of Credit shall be clean and irrevocable and
otherwise in a form sufficient for the beneficiary cedent to take credit on its
financial statements for reinsurance recoverables under applicable rules, laws
and regulations.

          (b) Immediately upon the issuance by any Fronting Lender of any
Fronted Letter of Credit, such Fronting Lender shall be deemed to have sold and
transferred to each Lender other than such Fronting Lender (each such Lender, in
its capacity under this Section 2.02(b), a "Fronting Participant"), and each
such Fronting Participant shall be deemed irrevocably and unconditionally to
have purchased and received from such Fronting Lender, without recourse or
warranty, an undivided interest and participation, to the extent of such
Fronting Participant's Applicable Percentage, in such Fronted Letter of Credit,
each drawing made thereunder and the obligations of each Account Party under
this Agreement with respect thereto, and any security therefor or guaranty
pertaining thereto. Upon any change in the Commitments or Applicable Percentages
of the Lenders pursuant to this Agreement (including pursuant to Section 2.16),
it is hereby agreed that, with respect to all outstanding Fronted Letters of
Credit and Fronted Unpaid Drawings, there shall be an automatic adjustment to
the participations pursuant to this Section 2.02 to reflect the new Applicable
Percentages of the assignor and assignee Lender or of all Lenders with
Commitments, as the case may be.

          (c) In the event that any Fronting Lender makes any payment under any
Fronted Letter of Credit and the respective Account Party shall not have
reimbursed such amount in full to such Fronting Lender pursuant to Section 2.05,
such Fronting Lender shall promptly notify the Administrative Agent, which shall
promptly notify each Fronting Participant, of such failure, and each Fronting
Participant shall promptly and unconditionally pay to such Fronting Lender the
amount of such Fronting Participant's Applicable Percentage of such unreimbursed
payment in Dollars and in immediately available funds. If, prior to 11:00 a.m.
(New York time) on any Business Day, the Administrative Agent so notifies any
Fronting Participant required to fund a payment under a Fronted Letter of
Credit, such Fronting Participant shall make available to such Fronting Lender
in Dollars and in immediately available funds such Fronting Participant's
Applicable Percentage of the amount of such payment on such Business Day (or, if
notice is given after 11:00 a.m. (New York time) on any Business Day, on the
next Business Day). If and to the extent such Fronting Participant shall not
have so made its Applicable Percentage of the amount of such payment available
to such Fronting Lender, such Fronting Participant agrees to pay to such
Fronting Lender, forthwith on demand, such amount, together with interest
thereon, for each day from such date to but excluding the date such amount is
paid to such Fronting Lender at the overnight Federal Funds Effective Rate. The
failure of any Fronting Participant to make available to such Fronting Lender
its Applicable Percentage of any payment under any Fronted Letter of Credit
shall not relieve any other Fronting Participant of its

                                       23

<PAGE>

obligation hereunder to make available to such Fronting Lender its Applicable
Percentage of any payment on the date required, as specified above, but no
Fronting Participant shall be responsible for the failure of any other Fronting
Participant to make available to such Fronting Lender such other Fronting
Participant's Applicable Percentage of any such payment.

          (d) Whenever any Fronting Lender receives any payment by any Account
Party as to which it has also received payments from the Fronting Participants
pursuant to paragraph (c) above, such Fronting Lender shall forward such payment
to the Administrative Agent, which in turn shall distribute to each Fronting
Participant which has paid its Applicable Percentage thereof, in Dollars and in
immediately available funds, an amount equal to such Fronting Participant's
share (based upon the amount funded by such Fronting Participant to the
aggregate amount funded by all Fronting Participants and retained by the
Fronting Lender) of the principal amount of such payment and interest thereon
accruing after the purchase of the respective participations.

          (e) The obligations of the Fronting Participants to make payments to
each Fronting Lender with respect to Fronted Letters of Credit issued by it
shall be irrevocable and not subject to any qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances, including any of the following circumstances:

               (i) any lack of validity or enforceability of this Agreement or
          any of the other Credit Documents or any amendment, supplement or
          modification to any of the foregoing;

               (ii) the existence of any claim, setoff, defense or other right
          which the Fronting Participant or any of its Affiliates may have at
          any time against a beneficiary named in a Fronted Letter of Credit,
          any transferee of any Fronted Letter of Credit (or any Person for whom
          any such transferee may be acting), the Administrative Agent, any
          Fronting Lender, any Fronting Participant, any Lender, or any other
          Person, whether in connection with this Agreement, any Fronted Letter
          of Credit, the transactions contemplated herein or any unrelated
          transactions (including any underlying transaction between any Account
          Party or any of its Affiliates and the beneficiary named in any such
          Fronted Letter of Credit);

               (iii) any draft, certificate or any other document presented
          under any Fronted Letter of Credit proving to be forged, fraudulent,
          invalid or insufficient in any respect or any statement therein being
          untrue or inaccurate in any respect;

               (iv) the surrender or impairment of any security for the
          performance or observance of any of the terms of any of the Credit
          Documents;

               (v) the occurrence of any Default or Event of Default; or

               (vi) any matter or event set forth in Section 2.05(b).

                                       24

<PAGE>

          (f) Upon the request of any Fronting Participant, each Fronting Lender
shall furnish to such Fronting Participant copies of any Fronted Letter of
Credit issued by it and such other documentation as may reasonably be requested
by such Fronting Participant.

          SECTION 2.03. Conditions to the Issuance of all Letters of Credit. (a)
Notwithstanding anything to the contrary set forth in this Article II, no LC
Issuer shall be under any obligation to issue any Letter of Credit if at the
time of such issuance:

          (i) any order, judgment or decree of any Governmental Authority or
     arbitrator shall purport by its terms to enjoin or restrain such LC Issuer
     from issuing such Letter of Credit or any requirement of law applicable to
     such LC Issuer or any Lender or any request or directive (whether or not
     having the force of law) from any Governmental Authority with jurisdiction
     over such LC Issuer or any Lender shall prohibit, or request that such LC
     Issuer or any Lenders refrain from, the issuance of letters of credit
     generally or the applicable type of letter of credit or shall impose upon
     such LC Issuer or any Lender with respect to the applicable type of letter
     of credit any restriction or reserve or capital requirement (for which such
     LC Issuer or such Lender is not otherwise compensated) not in effect on the
     Effective Date, or any unreimbursed loss, cost or expense which was not
     applicable, in effect or known to such LC Issuer, as of the Effective Date;

          (ii) the conditions precedent set forth in Section 4.02 are not
     satisfied at that time; or

          (iii) such LC Issuer shall have received notice from any Account Party
     or the Required Lenders prior to the issuance of such Letter of Credit of
     the type described in clause (v) of Section 2.03(b).

          (b) Notwithstanding anything to the contrary set forth in this Article
II,

          (i) no Letter of Credit shall be issued at any time when the Letter of
     Credit Outstandings exceed (or would after giving effect to such issuance
     exceed) the Total Commitment at such time;

          (ii) no Letter of Credit shall be issued for the account of any
     Account Party at any time when the Letter of Credit Outstandings
     attributable to such Account Party exceed (or would after giving effect to
     such issuance exceed) the Borrowing Base of such Account Party at such
     time;

          (iii) no Fronted Letter of Credit shall be issued by a Fronting Lender
     at any time if the Letter of Credit Outstandings in respect of all Fronted
     Letters of Credit issued by such Fronting Lender exceed (or would after
     giving effect to such issuance exceed) the maximum aggregate Stated Amount
     of all Fronted Letters of Credit that such Fronting Lender has agreed to
     issue in a separate agreement with the Company, if any;

          (iv) each Letter of Credit shall have an expiry date occurring not
     later than one year after such Letter of Credit's date of issuance,
     provided that, subject to Section 2.07, each such Letter of Credit may by
     its terms automatically renew annually for additional

                                       25

<PAGE>

     one-year periods unless the respective LC Issuer notifies the beneficiary
     thereof, in accordance with the terms of such Letter of Credit, that such
     Letter of Credit will not be renewed; and

          (v) no LC Issuer will issue any Letter of Credit after it has received
     written notice from any Account Party or the Required Lenders stating that
     a Default or an Event of Default exists until such time as the Issuing
     Agent shall have received a written notice of (x) rescission of such notice
     from the party or parties originally delivering the same or (y) a waiver of
     such Default or Event of Default by the Required Lenders (or such other
     number or percentage of the Lenders as shall be necessary under the
     circumstances as provided in Section 10.02).

          (c) Subject to and on the terms and conditions set forth herein, each
LC Issuer is hereby authorized by each Account Party and the Lenders to arrange
for the issuance of any Letter of Credit pursuant to Section 2.01(a) or 2.02(a)
and the amendment of any Letter of Credit pursuant to Section 2.08 and/or 10.02
by:

          (i) completing the commencement date and the expiry date of such
     Letter of Credit;

          (ii) (in the case of an amendment increasing or reducing the amount
     thereof) amending such Letter of Credit in such manner as such LC Issuer
     and the respective beneficiary may agree;

          (iii) in the case of Several Letters of Credit, completing such Letter
     of Credit with the participation of each Lender as allocated pursuant to
     the terms hereof; and

          (iv) in the case of Several Letters of Credit, executing such Letter
     of Credit on behalf of each Lender and following such execution delivering
     such Letter of Credit to the beneficiary of such Letter of Credit.

          SECTION 2.04. Letter of Credit Requests. (a) Whenever an Account Party
desires that a Letter of Credit be issued for its account, such Account Party
shall give the Administrative Agent and the respective LC Issuer written or
electronic notice (including by way of facsimile, e-mail or other electronic
transmission) thereof prior to 12:00 Noon (New York time) at least (x) three
Business Days in respect of Fronted Letters of Credit and (y) five Business Days
in respect of Several Letters of Credit, in each case, prior to the proposed
date of issuance (which shall be a Business Day), which notice shall be in the
form of Exhibit G or such other form reasonably acceptable to the Administrative
Agent (each, a "Letter of Credit Request"). Each Letter of Credit Request shall
include any other documents as the respective LC Issuer customarily and
generally requires in connection therewith, provided that in the case where
JPMorgan Chase Bank, National Association, The Bank of Nova Scotia, Deutsche
Bank AG New York Branch or any of their respective affiliates is the LC Issuer,
such additional documentation shall be limited to those set forth in Exhibit J
hereto (or such other documents as may be reasonably acceptable to both the
Company and the applicable LC Issuer).

          (b) The making of each Letter of Credit Request shall be deemed to be
a representation and warranty by the respective Account Party and the Company
that such Letter

                                       26

<PAGE>

of Credit may be issued in accordance with, and it will not violate the
requirements applicable to such Account Party and/or such Letter of Credit of,
Section 2.01 or 2.02, as the case may be, and Section 2.03.

          (c) Upon its issuance of, or amendment to, any Letter of Credit, the
respective LC Issuer shall promptly notify the respective Account Party and each
Lender of such issuance or amendment, which notice shall include a summary
description of the Letter of Credit actually issued and any amendments thereto.

          (d) The Stated Amount of each Letter of Credit upon issuance shall be
not less than $25,000.

          SECTION 2.05. Agreement to Repay Letter of Credit Drawings. (a) Each
Account Party severally agrees to reimburse (x) each Lender, by making payment
to the Administrative Agent in immediately available funds, for any payment or
disbursement made by such Lender under any Several Letter of Credit issued for
its account (each such amount so paid or disbursed until reimbursed, a "Several
Unpaid Drawing") and (y) the respective Fronting Lender directly for any payment
or disbursement made by such Fronting Lender under any Fronted Letter of Credit
issued for its account (each such amount so paid or disbursed until reimbursed,
a "Fronted Unpaid Drawing"), in each case, with interest on the amount so paid
or disbursed by such Lender, to the extent not reimbursed prior to 1:00 p.m.
(New York time) on the date of such payment or disbursement, from and including
the date paid or disbursed to but not including the date such Lender is
reimbursed therefor at a rate per annum which shall be the Alternate Base Rate
as in effect from time to time (plus an additional 2% per annum, payable on
demand, if not reimbursed by the third Business Day after the date on which the
respective Account Party receives notice from the respective LC Issuer of such
payment or disbursement).

          (b) Each Account Party's obligation under this Section 2.05 to
reimburse each Lender with respect to Unpaid Drawings of such Account Party
(including, in each case, interest thereon) shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff, counterclaim or
defense to payment which such Account Party may have or have had against such
Lender, or any LC Issuer, including any defense based upon the failure of any
drawing under a Letter of Credit to conform to the terms of the Letter of Credit
or any non-application or misapplication by the beneficiary of the proceeds of
such drawing; provided, however, that no Account Party shall be obligated to
reimburse any Lender for any wrongful payment made by such Lender under a Letter
of Credit as a result of acts or omissions constituting willful misconduct or
gross negligence on the part of such Lender (as determined by a court of
competent jurisdiction in a final and non-appealable judgment).

          (c) In determining whether to pay under any Letter of Credit, no LC
Issuer shall have any obligation relative to the other Lenders other than to
confirm that any documents required to be delivered under such Letter of Credit
appear to have been delivered and that they appear to substantially comply on
their face with the requirements of such Letter of Credit. Any action taken or
omitted to be taken by any LC Issuer under or in connection with any Letter of
Credit, if taken or omitted in the absence of such LC Issuer's gross negligence
or willful misconduct (as determined by a court of competent jurisdiction in a
final and non-appealable

                                       27

<PAGE>

judgment), shall not create for such LC Issuer any resulting liability to any
Account Party or any of its Affiliates or any Lender.

          SECTION 2.06. Increased Costs. If a Change in Law shall either (i)
impose, modify or make applicable any reserve, deposit, capital adequacy or
similar requirement against letters of credit issued by or participated in by
such Lender, or (ii) impose on such Lender any other conditions directly or
indirectly affecting this Agreement or any Letter of Credit; and the result of
any of the foregoing is to (A) increase the cost to such Lender of issuing,
maintaining or participating in any Letter of Credit, (B) reduce the amount of
any sum received or receivable by such Lender hereunder or (C) reduce the rate
of return on its capital with respect to Letters of Credit to a level below that
which such Lender would have achieved but for such Change in Law (and taking
into consideration such Lender's policies with respect to capital adequacy (or
those of its holding company), as generally applied), then, upon written demand
to the applicable Account Party by such Lender (with a copy to the
Administrative Agent), such Account Party shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such increased
cost or reduction. The preceding sentence shall not apply to increased costs
with respect to taxes imposed on or measured by the net income or net profits of
a Lender pursuant to the laws of the jurisdiction in or under the laws of which
it is organized or the jurisdiction in which the principal office or applicable
lending office of such Lender is located or in which it conducts a trade or
business or has a permanent establishment, or has a present or former connection
with such jurisdiction, or any subdivision thereof or therein or with respect to
Taxes to the extent that a Lender received additional amounts (or otherwise was
indemnified) for such Taxes pursuant to Section 2.12 (or would have received
additional amounts pursuant to Section 2.12(e) but for a failure to comply with
Section 2.12(e)). A certificate submitted to the applicable Account Party by
such Lender (with a copy to the Administrative Agent), setting forth (i) the
basis, in reasonable detail, for the determination of such additional amount or
amounts necessary to compensate such Lender as aforesaid and (ii) the basis, in
reasonable detail, for the computation of such amount or amounts, which shall be
consistently applied shall be final and conclusive and binding on the applicable
Account Party absent manifest error, although the failure to deliver any such
certificate shall not release or diminish such Account Party's obligations to
pay additional amounts pursuant to this Section 2.06 upon subsequent receipt of
such certificate. Notwithstanding the foregoing, no Account Party shall be
required to compensate any Lender pursuant to this Section 2.06 for any
increased costs or reductions incurred more than 180 days prior to the date that
such Lender notifies such Account Party of the applicable Change in Law;
provided that if the Change in Law giving rise to such increased costs or
reductions is retroactive, then such 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

          SECTION 2.07. Letter of Credit Expiration and Extensions. Each Lender
acknowledges that to the extent provided under the terms of any Letter of
Credit, the expiration date of such Letter of Credit will be automatically
extended for additional one-year periods, without written amendment, unless (a)
at least 30 days (or such other period required under or by any Legal
Requirement or Applicable Insurance Regulatory Authority) prior to the
expiration date of such Letter of Credit or (b) such extension would cause such
Letter of Credit to remain outstanding on or after the one-year anniversary of
the Commitment Expiration Date, notice is given by the respective LC Issuer in
accordance with the terms of the respective Letter of Credit (a "Notice of
Non-Extension") that the expiration date of such Letter of Credit will not be

                                       28

<PAGE>

extended beyond its current expiration date. The respective LC Issuer will give
Notices of Non-Extension as to any or all outstanding Letters of Credit if
requested to do so by the Required Lenders pursuant to Article VII. The
respective LC Issuer will give Notices of Non-Extension as to all outstanding
Letters of Credit (i) if the Commitment Expiration Date has occurred and (ii) on
the date necessary to prevent the extension described in the foregoing clause
(b). The respective LC Issuer will send a copy of each Notice of Non-Extension
to the respective Account Party concurrently with delivery thereof to the
respective beneficiary, unless prohibited by law from doing so.

          SECTION 2.08. Changes to Stated Amount. At any time when any Letter of
Credit is outstanding, at the request of the respective Account Party, the
Issuing Agent will enter into an amendment increasing or reducing the Stated
Amount of such Letter of Credit, provided that (i) in no event shall the Stated
Amount of such Letter of Credit be increased to an amount which would cause (x)
the Letter of Credit Outstandings to exceed the Total Commitment at such time,
(y) the Letter of Credit Outstandings attributable to such Account Party to
exceed the Borrowing Base of such Account Party at such time or (z) with respect
to a Fronted Letter of Credit, the Letter of Credit Outstandings in respect of
all Fronted Letters of Credit issued by the applicable Fronting Lender to exceed
the maximum aggregate Stated Amount of all Fronted Letters of Credit that such
Fronting Lender has agreed to issue in a separate agreement with the Company,
(ii) the Stated Amount of a Letter of Credit may not be increased at any time if
the conditions precedent set forth in Section 4.02 are not satisfied at such
time, and (iii) the Stated Amount of a Letter of Credit may not be increased at
any time after the Commitment Expiration Date.

          SECTION 2.09. Termination and Reduction of Commitments. (a) Unless
previously terminated, the Total Commitment (and the Commitment of each Lender)
shall terminate on the Commitment Expiration Date.

          (b) The Company may at any time terminate, or from time to time
reduce, the Total Commitment; provided that (i) each reduction of the Total
Commitment shall be in an amount that is an integral multiple of $1,000,000 and
not less than $5,000,000 and (ii) the Company shall not terminate or reduce the
Total Commitment if, after giving effect to such termination or reduction, the
Letter of Credit Outstandings would exceed the Total Commitment. Each such
reduction shall be applied to the Commitments of the Lenders on a pro rata basis
based on the amount of such Lenders' respective Commitments.

          (c) The Company shall notify the Administrative Agent of any election
to terminate or reduce the Total Commitment under paragraph (b) of this Section
2.09 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
Company pursuant to this Section shall be irrevocable; provided that a notice of
termination of Commitments may state that such notice is conditioned upon the
effectiveness of other credit facilities or other alternative financing, in
which case such notice may be revoked without penalty prior to the specified
time if such condition is not satisfied. Any termination or reduction of the
Total Commitment (or the Commitments of any Lender) shall be permanent. Each

                                       29

<PAGE>

reduction of the Total Commitment shall be made ratably among the Lenders in
accordance with their respective Commitments.

          SECTION 2.10. Prepayment; Additional Borrowing Base Requirements. (a)
If (i) as of the Commitment Expiration Date, any Letter of Credit may for any
reason remain outstanding, (ii) at any time, the aggregate amount of all Letter
of Credit Outstandings exceeds the Total Commitment as then in effect, (iii) any
Event of Default occurs and is continuing and the Administrative Agent or the
Required Lenders, as applicable, require the Company and the other Account
Parties to pay to the Collateral Account additional amounts of cash and Cash
Equivalents, to be held as security for each Account Party's reimbursement
obligations in respect of Letters of Credit then outstanding or (iv) an Event of
Default set forth under Section 7.05 occurs and is continuing, then the Company
shall, or shall cause one or more other Account Parties to, pay or deliver to
the Administrative Agent on such date an amount of cash or Cash Equivalents to
be deposited in the Collateral Account applicable to each Account Party and to
be held as additional security for the obligations of each of the Account
Parties hereunder such that the amount of cash and Cash Equivalents in the
Collateral Account applicable to each Account Party would equal the aggregate
amount of all Letter of Credit Outstandings and other obligations attributable
to such Account Party hereunder. If at any time the Administrative Agent
determines that any funds held in the Collateral Account pursuant to this
Section 2.10(a) are subject to any right or claim of any Person other than the
Agents (on behalf of the Lenders) or that the total amount of such funds is less
than the aggregate amount of all Letter of Credit Outstandings and other
obligations of the Account Parties hereunder, the Company shall, or shall cause
one or more Account Parties to, forthwith upon demand by the Administrative
Agent, pay to the Administrative Agent, as additional funds to be deposited and
held in the Collateral Account as aforesaid, an amount equal to the excess of
(a) the aggregate amount of all Letter of Credit Outstandings and other
obligations of the Account Parties hereunder over (b) the total amount of cash
and Cash Equivalents deposited in the Collateral Account that the Administrative
Agent reasonably determines to be free and clear of any such right and claim.
With respect to any payment to the Collateral Account required by clause (iii)
of the first sentence of this Section 2.10(a), such payment shall (to the extent
not applied to the applicable reimbursement obligations) be returned to the
Company within three Business Days after the applicable Event of Default shall
have been cured or waived.

          (b) If on any date the Letter of Credit Outstandings attributable to
any Account Party exceed the Borrowing Base of such Account Party at such time,
such Account Party agrees to (i) in the case of the Company, within two Business
Days of the date on which the Company receives notice from the Administrative
Agent that the Letter of Credit Outstandings attributable to the Company exceed
the Company's Borrowing Base, pay or deliver to the Collateral Agent an amount
of cash or Eligible Securities (valued for this purpose based on the respective
Advance Rate applicable thereto) in an aggregate amount equal to such excess,
with any such cash or Eligible Securities to be held as additional security for
all obligations of the Company hereunder in the Collateral Account applicable to
the Company and (ii) in the case of any other Account Party, within two Business
Days of the date on which the Company or such Account Party receives notice from
the Administrative Agent that the Letter of Credit Outstandings attributable to
such Account Party exceed such Account Party's Borrowing Base, pay or deliver to
the Collateral Agent an amount of cash or Eligible Securities (valued for this
purpose based on the respective Advance Rate applicable thereto) in an aggregate
amount equal

                                       30

<PAGE>

to such excess, with any such cash or Eligible Securities to be held as
additional security for all obligations of such Account Party hereunder in the
Collateral Account applicable to such Account Party, which amounts shall be
returned within three Business Days after such excess is cured.

          SECTION 2.11. Fees. (a) Each Account Party jointly and severally
agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee, which shall accrue at the Applicable Commitment Fee Rate on the
daily amount of the unutilized Commitment of such Lender during the period from
and including the Effective Date to but excluding the Commitment Expiration
Date. Accrued commitment fees shall be payable in arrears on the last day of
March, June, September and December of each year and on the Commitment
Expiration 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 365 days
(or 366 days in a leap year) and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

          (b) The Company agrees to pay to each Agent, for its own account, fees
payable in the amounts and at the times separately agreed upon between the
Company and the applicable Agent.

          (c) Each Account Party severally agrees to pay to the Administrative
Agent for pro rata distribution to each Lender (based on their respective
Applicable Percentages), a fee in respect of each Letter of Credit issued for
the account of such Account Party (the "Letter of Credit Fee") computed at a
rate per annum equal to the Applicable Letter of Credit Fee Rate on the daily
Stated Amount of such Letter of Credit. Accrued Letter of Credit Fees shall be
due and payable in arrears on the last day of March, June, September and
December of each year and upon the first day after the termination of the Total
Commitment upon which no Letters of Credit remain outstanding. All Letter of
Credit Fees shall be computed on the basis of a year of 365 days (or 366 days in
a leap year) and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

          (d) Each Account Party severally agrees to pay to each Fronting
Lender, for its own account, a fronting fee in respect of, and fees with respect
to the issuance, amendment, renewal or extension of, or processing of drawings
under, each Fronted Letter of Credit issued by such Fronting Lender for the
account of such Account Party, in each case in amounts and on dates as shall
have separately been agreed to by the Company and such Fronting Lender. Each
Account Party severally agrees to pay to the Issuing Agent fees with respect to
the issuance, amendment, renewal or extension of, and processing of drawings
under, each Several Letter of Credit issued for the account of such Account
Party, in each case in amounts and on dates as shall have separately been agreed
to by the Company and the Issuing Agent.

          (e) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent for distribution to the
Persons entitled thereto as set forth above. Fees paid shall not be refundable
under any circumstances. If any fee or other amount payable by any Account Party
hereunder is not paid when due, such overdue amount shall bear interest, after
as well as before judgment, at a rate per annum equal to the Alternate Base Rate
plus 2% per annum. All interest hereunder shall be computed on the basis of a
year of

                                       31

<PAGE>

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 Alternate Base Rate shall be
determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

          SECTION 2.12. Taxes. (a) Any and all payments by or on account of any
obligation of any Account Party hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if
such Account Party 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, Issuing Agent or Lender (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) such
Account Party shall make such deductions and (iii) such Account Party shall pay
the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

          (b) In addition, each Account Party shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c) Each Account Party severally (and not jointly) agrees to indemnify
the Administrative Agent, the Issuing Agent and each Lender within 10 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes that such Account Party failed to deduct or withhold and that were paid by
the Administrative Agent, the Issuing Agent or such Lender on or with respect to
any payment by or on account of any obligation of such Account Party hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable out-of-pocket 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 (with reasonable detail) delivered to
any Account Party by a Lender or by the Administrative Agent or the Issuing
Agent on its own behalf or on behalf of a Lender, shall be conclusive absent
manifest error.

          (d) As soon as reasonably practicable after any payment of Indemnified
Taxes or Other Taxes by any Account Party to a Governmental Authority, such
Account Party 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) Each Lender shall, to the extent it may lawfully do so, deliver to
the Company (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Company (if any), or
will comply with such other requirements, if any, as is currently applicable, as
will permit payments under this Agreement to be made without withholding or at a
reduced rate.

                                       32

<PAGE>

          (f) If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to
which it has been indemnified by any Account Party or with respect to which such
Account Party has paid additional amounts pursuant to this Section 2.12, it
shall pay over such refund to such Account Party (but only to the extent of
indemnity payments made, or additional amounts paid, by such Account Party under
this Section 2.12 with respect to the Taxes or Other Taxes giving rise to such
refund), net of all reasonable out-of-pocket expenses of the Administrative
Agent or such Lender incurred in obtaining such refund and without interest
(other than any interest paid by the relevant Governmental Authority with
respect to such refund); provided that such Account Party, upon the request of
the Administrative Agent or such Lender, agrees to repay the amount paid over to
such Account Party (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Lender in
the event the Administrative Agent or such Lender is required to repay such
refund to such Governmental Authority. This Section shall not be construed to
require the Administrative Agent or any Lender to make available its tax returns
(or any other information relating to its taxes which it deems confidential) to
such Account Party or any other Person.

          (g) Any Lender that is not a Lender as of the Effective Date shall not
be entitled to any greater payment under this Section 2.12 than such Lender's
assignor could have been entitled to absent such assignment except to the extent
that the entitlement to a greater payment resulted from a Change in Law.

          SECTION 2.13. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) Each Account Party shall make each payment required to be made by
it hereunder (whether of principal, interest, fees or of amounts payable under
Section 2.06 or 2.12 or otherwise, except as expressly set forth in Section
2.05) prior to 12:00 noon (or, in the case of any prepayment or repayment in
full of all outstanding Letters of Credit, 2:00 p.m.), New York City time, on
the date when due, in immediately available funds, without set-off or
counterclaim in Dollars. 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
thereon. All such payments shall be made to the Administrative Agent at its
offices at 1111 Fannin, 8th floor, Houston, Texas 77002, except that payments
pursuant to Sections 2.06, 2.12 and 10.03 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments
received by it for the 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.

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

                                       33

<PAGE>

          (c) 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 Unpaid Drawings or any fees payable pursuant to Section
2.11 resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of such obligations then due and owed to such Lender, then the
Lender receiving such greater proportion shall purchase (for cash at face value)
participations in such obligations of the respective Account Party or the
Company, as the case may be, owed to such Lenders to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably;
provided that (i) if any such participations are 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 Account Party 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 Commitment to any assignee or participant, other than to any Account
Party or any Subsidiary or Affiliate thereof (as to which the provisions of this
paragraph shall apply). Each Account Party 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 Account Party rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of such
Account Party in the amount of such participation.

          (d) Unless the Administrative Agent shall have received notice from
the relevant Account Party prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders hereunder that such Account
Party will not make such payment, the Administrative Agent may assume that such
Account Party has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders the amount due. In
such event, if the relevant Account Party has not in fact made such payment,
then each of the Lenders severally agrees to repay to the Administrative Agent
forthwith on demand the amount so distributed to such 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
greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation.

          (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.13(d), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender's obligations under such Section until all such
unsatisfied obligations are fully paid.

          SECTION 2.14. Mitigation Obligations; Replacement of Lenders. (a) If
any Lender requests compensation under Section 2.06, or if each Account Party is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.06 or Section
2.12, then such Lender shall use reasonable efforts to designate a different
lending office for issuing or funding its Letters of Credit 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

                                       34

<PAGE>

amounts payable pursuant to Section 2.06 or 2.12, 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. Each Account
Party hereby jointly and severally agrees to pay all reasonable costs and
expenses incurred by any Lender in connection with any such designation or
assignment.

          (b) If any Lender requests compensation under Section 2.06, or if each
Account Party is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.06 or
Section 2.12, then, in each case, the Company, at its sole expense and effort,
shall have the right, if no Default or Event of Default then exists, to replace
such Lender (the "Replaced Lender"), with one or more Person or Persons
(collectively, the "Replacement Lender") reasonably acceptable to the
Administrative Agent at which time the Replaced Lender shall 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 the Replacement Lender; provided that (i) at the time of any
replacement pursuant to this Section 2.14, the Replacement Lender and the
Replaced Lender shall enter into one or more Assignment and Assumptions pursuant
to Section 10.04(b) (and with all fees payable pursuant to said Section 10.04(b)
to be paid by the Replacement Lender) pursuant to which the Replacement Lender
shall acquire all of the Commitments of the Replaced Lender and, in connection
therewith, shall pay to the Replaced Lender in respect thereof an amount equal
to the sum of (A) an amount equal to all Unpaid Drawings that have been funded
by (and not reimbursed to) such Replaced Lender, together with all then unpaid
interest with respect thereto at such time and (B) an amount equal to all
accrued, but theretofore unpaid, fees owing to the Replaced Lender pursuant to
Section 2.11; (ii) all obligations of each Account Party under the Credit
Documents owing to the Replaced Lender (other than those specifically described
in clause (i) above in respect of which the assignment purchase price has been,
or is concurrently being, paid), shall be paid in full to such Replaced Lender
concurrently with such replacement; (iii) no assignment pursuant to this Section
2.14 shall be effective until all of the then outstanding Several Letters of
Credit are returned by each respective beneficiary to the Issuing Agent for
cancellation in exchange for new or amended Several Letters of Credit which give
effect to such assignment (it being understood that to the extent the respective
beneficiaries do not consent to such assignment, such assignment cannot occur);
(iv) the Company shall have received the prior written consent of the
Administrative Agent and each Fronting Lender, which consents shall not be
unreasonably withheld or delayed; (v) such assignment will result in a reduction
in such compensation or payments; and (vi) no Lender shall be required to become
a Replaced Lender if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Company to require such assignment
and delegation cease to apply. Upon the execution of the respective Assignment
and Assumption, the payment of amounts referred to in clauses (i) and (ii) above
and the return, and cancellation and exchange of each then outstanding Several
Letter of Credit as provided above, the Replacement Lender shall become a Lender
hereunder and the Replaced Lender shall cease to constitute a Lender hereunder,
except with respect to indemnification provisions applicable to the Replaced
Lender under this Agreement, which shall survive as to such Replaced Lender. For
the avoidance of doubt, no Replaced Lender shall be required to execute, sign or
deliver any document or assignment in order to be replaced in accordance with
this Section 2.14.

          SECTION 2.15. Designated Subsidiary Account Parties. The Company may
from time to time designate one or more Persons as an additional Designated
Subsidiary Account Party, subject to the following terms and conditions:

          (a) each such Person shall be a Wholly-Owned Subsidiary of the
Company;

          (b) each such Designated Subsidiary Account Party shall enter into an
appropriately completed DSAP Assumption Agreement on or prior to the date of
designation hereof;

          (c) on or prior to the date of designation, the Administrative Agent
shall have received from such Person a certificate, signed by an Authorized
Officer of such Person in the form of Exhibit F or such other form reasonably
acceptable to the Administrative Agent with appropriate insertions or deletions,
together with (x) copies of its certificate of incorporation, by-laws or other
organizational documents and (y) the resolutions of the board of directors (or
similar governing body) of such Person relating to the Credit Documents which
shall be reasonably satisfactory to the Administrative Agent;

          (d) on or prior to the date of designation, the Administrative Agent
shall have received an opinion, addressed to the Administrative Agent and each
of the Lenders and dated the date of designation, which opinion shall be in form
and substance reasonably satisfactory to the Administrative Agent, from counsel
to the respective Designated Subsidiary Account Party reasonably satisfactory to
the Administrative Agent, covering certain of the matters set forth in the
opinions of counsel delivered to the Administrative Agent on the Effective Date
pursuant to Section 4.01(b)(iii), as may be reasonably requested by the
Administrative Agent, and such other matters incident to the transactions
contemplated thereby as the Administrative Agent may reasonably request; and

          (e) in the case of any Designated Subsidiary Account Party which is a
Regulated Insurance Company, the Administrative Agent and its counsel shall be
reasonably satisfied with all applicable laws and/or regulations of each
jurisdiction having legal or regulatory jurisdiction over such Designated
Subsidiary Account Party as such laws and/or regulations relate to the
enforceability, perfection or priority of the Liens created or purported to be
created under the Security Documents as between the Secured Creditors and any
Applicable Insurance Regulatory Agency or the policy holders with respect to
such Regulated Insurance Company.

          SECTION 2.16. Additional Commitments. (a) The Company shall have the
right, at any time and from time to time, after the Effective Date and prior to
the Commitment Expiration Date to request (so long as no Default or Event of
Default is then in existence or would result therefrom) on one or more occasions
that one or more existing Lenders (and/or one or more other Eligible Persons
which will become Lenders as provided pursuant to clause (vi) below) provide
Additional Commitments; it being understood and agreed, however, that (i) no
existing Lender shall be obligated to provide an Additional Commitment as a
result of any request by the Company, (ii) until such time, if any, as (x) such
existing Lender has agreed in its sole discretion to provide an Additional
Commitment and executed and delivered to the Administrative Agent an Additional
Commitment Agreement in respect thereof as provided in

                                       36

<PAGE>

Section 2.16(b) and (y) such other conditions set forth in Section 2.16(b) shall
have been satisfied, such existing Lender shall not be obligated to issue, or
participate in, Letters of Credit, in excess of the amounts provided for herein,
immediately before giving effect to such Additional Commitments provided by such
existing Lender pursuant to this Section 2.16, (iii) any existing Lender may
provide an Additional Commitment without the consent of any other Lender, (iv)
(A) each provision of Additional Commitments on a given date pursuant to this
Section 2.16 shall be in a minimum aggregate amount (for all Additional
Commitment Lenders (including, in the circumstances contemplated by clause (vi)
below, Eligible Persons who will become Additional Commitment Lenders) of at
least $25,000,000 and (B) the aggregate amount of Additional Commitments
provided pursuant to this Section 2.16 shall not exceed $200,000,000, (v) all
up-front fees payable to any Additional Commitment Lender shall be as set forth
in the relevant Additional Commitment Agreement, (vi) if, on or after the tenth
Business Day following the request by the Company of the then existing Lenders
to provide Additional Commitments pursuant to this Section 2.16 on the terms to
be applicable thereto, the Company has not received Additional Commitments in an
aggregate amount equal to that amount of the Additional Commitments which the
Company desires to obtain pursuant to such request (as set forth in the request
provided by the Company to the Administrative Agent as provided above), then the
Company may request Additional Commitments from Eligible Persons which are
reasonably acceptable to the Administrative Agent and each Fronting Lender in an
aggregate amount equal to such deficiency on terms which are no more favorable
to such Eligible Person in any respect than the terms offered to the existing
Lenders, (vii) all Additional Commitments provided on a given date pursuant to
this Section 2.16 shall have the same terms and conditions as all then existing
Commitments and shall be added to such existing Commitments in accordance with
clause (b) of this Section 2.16 below and (viii) all actions taken by the
Account Party pursuant to this Section 2.16 shall be done in coordination with
the Administrative Agent.

          (b) At the time of any provision of Additional Commitments pursuant to
this Section 2.16, (i) the Company, each Designated Subsidiary Account Party,
the Administrative Agent and each existing Lender or Eligible Person, as the
case may be, which agrees to provide an Additional Commitment (each, an
"Additional Commitment Lender") shall execute and deliver to the Administrative
Agent an Additional Commitment Agreement substantially in the form of Exhibit E
or such other form reasonably acceptable to the Administrative Agent, subject to
such modifications in form and substance reasonably satisfactory to the
Administrative Agent as may be necessary or appropriate (with the effectiveness
of such Additional Commitment Lender's Additional Commitment to occur upon
delivery of such Additional Commitment Agreement to the Administrative Agent,
the payment of any fees required in connection therewith and the satisfaction of
the other conditions set forth in this Section 2.16 to the reasonable
satisfaction of the Administrative Agent), (ii) all Several Letters of Credit
outstanding at such time shall have been returned by each respective beneficiary
thereunder to the respective Issuing Agent and shall either have been cancelled
and/or exchanged for new or amended Letters of Credit which give effect to such
Additional Commitments, and such Additional Commitment Lenders, (iii) if such
Additional Commitment Lender is not a United States person (as such term is
defined in Section 7701(a)(3) of the Code) for U.S. Federal income tax purposes
or would otherwise constitute a Foreign Lender, such Additional Commitment
Lender shall provide to the Company the appropriate documentation described in
Section 2.12(e), (iv) the Company and each Designated Subsidiary Account Party
shall deliver to the Administrative Agent resolutions

                                       37

<PAGE>

authorizing the incurrence of the obligations to be incurred pursuant to each
Additional Commitment, together with evidence of good standing of the Company
and each Designated Subsidiary Account Party and (v) the Company and each
Designated Subsidiary Account Party shall deliver to the Administrative Agent an
opinion, in form and substance reasonably satisfactory to the Administrative
Agent, from counsel to the Company and such Designated Subsidiary Account Party
reasonably satisfactory to the Administrative Agent and dated such date,
covering certain matters similar to those set forth in the opinions of counsel
delivered to the Lenders on the Effective Date pursuant to Section 4.01(b) and
such other matters as the Administrative Agent may reasonably request. The
Administrative Agent shall promptly notify each Lender as to the occurrence of
each Additional Commitment Date, and (x) on each such date, the Total Commitment
under, and for all purposes of, this Agreement and each other Credit Document
shall be increased by the aggregate amount of such Additional Commitments and
(y) on each such date, the Commitment Schedule shall be deemed modified to
reflect the revised Commitments of each affected Lender.

          SECTION 2.17. Existing Secured Fronted Letters of Credit. It is hereby
agreed and acknowledged that (a) all letters of credit described on Schedule
2.17 (the "Existing Secured Fronted Letters of Credit") which were issued under
the Existing LC Facility and which remain outstanding on the Effective Date
shall be deemed issued under this Agreement as a "Fronted Letter of Credit" on
the Effective Date, (b) all references to the Existing LC Facility or any other
Credit Document (as defined in the Existing LC Facility) contained in such
Existing Secured Fronted Letters of Credit or the related documentation shall be
deemed to be references to this Agreement or the applicable Credit Documents (as
defined herein), as the case may be, and (c) the Existing LC Issuer shall be
deemed to be an LC Issuer hereunder for all purposes to the extent relating to
such Existing Secured Fronted Letters of Credit. For the avoidance of doubt, on
and after the Effective Date, all fees and rates payable or accruing on or in
respect of outstanding Existing Secured Fronted Letters of Credit shall be at
the rates set forth in this Agreement and not at the rates set forth in the
Existing LC Facility.

          SECTION 2.18. Existing Secured Several Letters of Credit.

          (a) It is hereby agreed and acknowledged that (i) all letters of
credit described on Schedule 2.18 that are not Existing Secured Fronted Letters
of Credit (the "Existing Secured Several Letters of Credit") which were issued
under the Existing LC Facility and which remain outstanding on the Effective
Date shall be deemed issued under this Agreement as a "Several Letter of Credit"
on the Effective Date, (ii) all references to the Existing LC Facility or any
other Credit Document (as defined in the Existing LC Facility) contained in such
Existing Secured Several Letters of Credit or the related documentation shall be
deemed to be references to this Agreement or the applicable Credit Documents (as
defined herein), as the case may be, and (iii) the Existing LC Issuer shall be
deemed to be an LC Issuer hereunder for all purposes to the extent relating to
such Existing Secured Several Letters of Credit. As soon as possible following
the Effective Date, each Existing Secured Several Letter of Credit shall be
amended to replace each Existing Lender with each Lender party to this Agreement
at the time of such amendment in accordance with each such Lender's Applicable
Percentage. Until an Existing Secured Several Letter of Credit has been amended
in accordance with this Section 2.18, each Existing Lender shall be deemed to
have sold and transferred to each Lender, and each such Lender shall be deemed
irrevocably and unconditionally to have purchased and received from such
Existing

                                       38

<PAGE>

Lender, without recourse or warranty, an undivided interest and participation,
to the extent of such Lender's Applicable Percentage, in such Existing Secured
Several Letter of Credit, each substitute Existing Secured Several Letter of
Credit, each drawing made thereunder, the obligations of the respective Account
Party under this Agreement with respect thereto and any security therefore or
guaranty pertaining thereto. Upon any change in the Commitments or Applicable
Percentages of the Lenders pursuant to this Agreement, it is hereby agreed that,
with respect to all outstanding Existing Secured Several Letters of Credit and
Unpaid Drawings with respect thereto, there shall be an automatic adjustment to
the participations pursuant to this Section 2.18 to reflect the new Applicable
Percentages from such change or changes, as the case may be. For the avoidance
of doubt, on and after the Effective Date, all fees and rates payable or
accruing on or in respect of outstanding Existing Secured Several Letters of
Credit shall be at the rates set forth in this Agreement and not at the rates
set forth in the Existing LC Facility.

          (b) In determining whether to pay under any Existing Secured Several
Letter of Credit, no Existing Lender shall have any obligation relative to the
Lenders other than to confirm that any documents required to be delivered under
such Existing Secured Several Letter of Credit have been delivered and that they
appear to substantially comply on their face with the requirements of such
Existing Secured Several Letter of Credit, which obligation, it is understood,
is being performed by the Issuing Agent, and upon whom each Existing Lender
shall be entitled to rely. Any action taken or omitted to be taken by the
Issuing Agent or any Existing Lender under or in connection with any Existing
Secured Several Letter of Credit issued by it shall not create for the Issuing
Agent or such Existing Lender any resulting liability to any Account Party, any
Lender or any other Person unless such action is taken or omitted to be taken
with gross negligence or willful misconduct on the part of the Issuing Agent or
such Existing Lender, as the case may be (as determined by a court of competent
jurisdiction).

          (c) In the event that any Existing Lender makes any payment under any
Existing Secured Several Letter of Credit issued by it and the respective
Account Party shall not have reimbursed such amount in full as provided in
Section 2.05, upon notification of such failure by such Existing Lender to the
Administrative Agent, the Administrative Agent shall promptly notify each Lender
of such failure, and each such Lender shall promptly and unconditionally pay to
the Administrative Agent for the account of such Existing Lender, the amount of
such Lender's Applicable Percentage of such payment in Dollars and in
immediately available funds. If the Administrative Agent so notifies any Lender
required to fund a payment under an Existing Secured Several Letter of Credit
prior to 11:00 a.m. (New York time) on any Business Day, such Lender shall make
available to the Administrative Agent at the its office referenced in Section
2.13(a) for the account of the respective Existing Lender such Lender's
Applicable Percentage of the amount of such payment on such Business Day in
immediately available funds (and, to the extent such notice is given after 11:00
a.m. (New York time) on any Business Day, such Lender shall make such payment on
the immediately following Business Day). If and to the extent such Lender shall
not have so made its Applicable Percentage of the amount of such payment
available to the Administrative Agent for the account of the respective Existing
Lender, such Lender agrees to pay to the Administrative Agent for the account of
such Existing Lender, forthwith on demand such amount, together with interest
thereon, for each day from such date until the date such amount is paid to the
Administrative Agent for the account of the Existing Lender at the overnight
Federal Funds Effective Rate. The failure of any Lender to make available to the
Administrative Agent for the account of the respective Existing Lender its

                                       39

<PAGE>

Applicable Percentage of any payment under any Existing Secured Several Letter
of Credit issued by it shall not relieve any other Lender of its obligation
hereunder to make available to the Administrative Agent for the account of such
Existing Lender its Applicable Percentage of any payment under any such Existing
Secured Several Letter of Credit on the date required, as specified above, but
no Lender shall be responsible for the failure of any other Lender to make
available to the Administrative Agent for the account of such Existing Lender
such other Lender's Applicable Percentage of any such payment.

          (d) Whenever the Administrative Agent receives a payment of a
reimbursement obligation for the account of any Existing Lender, the
Administrative Agent shall promptly pay to each Lender which has paid its
Applicable Percentage thereof in immediately available funds, an amount equal to
such Lender's Applicable Percentage of the principal amount thereof and interest
thereon accruing after the purchase of the respective participations.

          (e) The obligations of the Lenders to make payments to the
Administrative Agent for the account of the respective Existing Lender with
respect to Existing Secured Several Letters of Credit issued by it shall be
irrevocable and not subject to counterclaim, set-off or other defense or any
other qualification or exception whatsoever and shall be made in accordance with
the terms and conditions of this Agreement under all circumstances, including,
without limitation, any of the following circumstances:

          (i) any lack of validity or enforceability of this Agreement or any of
     the other Credit Documents;

          (ii) the existence of any claim, set-off, defense or other right which
     the Company or any of its Subsidiaries may have at any time against a
     beneficiary named in an Existing Secured Several Letter of Credit, any
     transferee of any Existing Secured Several Letter of Credit (or any Person
     for whom any such transferee may be acting), the Administrative Agent, any
     Existing Lender, or other Person, whether in connection with this
     Agreement, any Existing Secured Several Letter of Credit, the transactions
     contemplated herein or any unrelated transactions (including any underlying
     transaction between the Company or any of its Subsidiaries and the
     beneficiary named in any such Existing Secured Several Letter of Credit);

          (iii) any draft, certificate or other document presented under the
     Existing Secured Several Letter of Credit proving to be forged, fraudulent,
     invalid or insufficient in any respect or any statement therein being
     untrue or inaccurate in any respect;

     or observance of any of the terms of any of the Credit Documents; or

          (v) the occurrence of any Default or Event of Default.

provide a mechanic whereby the Existing Secured Several Letters of Credit are
replaced with Several Letters of Credit under this Agreement and, other than the
payment of standard amendment fees and commissions to the Issuing Agent, not to
create any additional liability or obligation on any

          Each of the Company and each Designated Subsidiary Account Party, in
each case, on behalf of itself and the Subsidiaries represents and warrants to
the Lenders that:

          SECTION 3.01. Corporate Status. Each of the Company and each of its
Subsidiaries (i) is a duly organized and validly existing corporation or
business trust or other entity in good standing under the laws of the
jurisdiction of its organization and has the corporate or other organizational
power and authority to own its property and assets and to transact the business
in which it is engaged and presently proposes to engage, and (ii) has been duly
qualified and is authorized to do business and is in good standing in all
jurisdictions where it is required to be so qualified, except, in the case of
this clause (ii), where the failure to be so qualified, authorized or in good
standing, either individually or in the aggregate, has not had, and would not
reasonably be expected to have, a Material Adverse Effect.

          SECTION 3.02. Corporate Power and Authority. Each Account Party has
the corporate power and authority to execute, deliver and carry out the terms
and provisions of the Credit Documents to which it is a party and has taken all
necessary corporate action to authorize the execution, delivery and performance

each Credit Document to which it is a party and each such Credit Document
constitutes the legal, valid and binding obligation of such Account Party
enforceable against such Account Party in accordance with its terms, except to
the extent that enforceability thereof may be limited by applicable bankruptcy,
insolvency, moratorium or similar laws affecting creditors' rights generally and
general principles of equity regardless of whether enforcement is sought in a
proceeding in equity or at law.

          SECTION 3.03. No Contravention of Agreements or Organizational
Documents. Neither the execution, delivery and performance by any Account Party
of this Agreement or the other Credit Documents to which it is a party nor
compliance with the terms and provisions thereof, nor the consummation of the
transactions contemplated therein, (i) will contravene any applicable provision
of any law, statute, rule, regulation, order, writ, injunction or decree of any
court or governmental instrumentality, (ii) will conflict or be inconsistent
with or result in any breach of any of the terms, covenants, conditions or
provisions of, or constitute a default under, or result in the creation or
imposition of (or the obligation to create or impose) any Lien (other than Liens
in favor the Administrative Agent and the Lenders pursuant to the Security
Documents) upon any of the property or assets of the Company or any of its
Subsidiaries pursuant to the terms of, any indenture, mortgage, deed of trust,
loan agreement, credit agreement or any other material instrument to which the
Company or any of its Subsidiaries is a party or by which it or any of its
property or assets are bound or to which it may be subject or (iii) will violate
any provision of the certificate of incorporation, by-laws or other
organizational documents of the Company or any of its Subsidiaries.

actions, suits or proceedings pending or, to the best knowledge of the Company
or any of its Subsidiaries, threatened involving the Company or any of its
Subsidiaries (including with respect to this Agreement or any other Credit
Document) that, either individually or in the aggregate, have had, or would
reasonably be expected to have, a Material Adverse Effect. Except for any
matters that, either individually or in the aggregate, have not had, and would
not reasonably be expected to have, a Material Adverse Effect, neither the
Company nor any of its Subsidiaries (i) has failed to comply with any
Environmental Law or to obtain, maintain or comply with any permit, license or
other approval required under any Environmental Law, (ii) has become subject to
any Environmental Liability, (iii) has received notice of any claim with respect
to any Environmental Liability or (iv) knows of any basis for any Environmental

only be utilized to support Letter of Credit Supportable Obligations.

          SECTION 3.06. Approvals. Any (a) order, consent, approval, license,

third party approval, permit or license required to be obtained, in each case in
connection with (i) the Transaction or (ii) the legality, validity, binding
effect or enforceability of any Credit Document, has been obtained and is in
full force and effect.

          SECTION 3.07. Investment Company Act. No Account Party is an
"investment company" or a company "controlled" by an "investment company,"
within the meaning of the Investment Company Act of 1940, as amended.

          SECTION 3.08. True and Complete Disclosure; Projections and
Assumptions. All factual information (taken as a whole) heretofore or
contemporaneously furnished by the Company or any of its Subsidiaries to the
Administrative Agent or any Lender (including all information contained in the
Credit Documents) for purposes of or in connection with this Agreement or any
transaction contemplated herein is, and all other factual information (taken as
a whole with all other such information theretofore or contemporaneously
furnished) hereafter furnished by any such Persons to the Administrative Agent
or any Lender will be, true and accurate in all material respects on the date as
of which such information is dated and not incomplete by omitting to state any
material fact necessary to make such information (taken as a whole with all
other such information theretofore or contemporaneously furnished) not
misleading at such time in light of the circumstances under which such
information was provided; provided that with respect to projections, the Company
or the applicable Designated Subsidiary Account Party represents only that the
projections contained in such materials are based on good faith estimates and
assumptions believed by the Company to be reasonable and attainable at the time
made, it being recognized by the Administrative Agent and the Lenders that such
projections as to future events are not to be viewed as facts and are subject to
significant uncertainties and contingencies many of which are beyond the
Company's control and that actual results during the period or periods covered
by any such projections may differ from the projected results.

furnished to the Lenders its consolidated balance sheet and consolidated
statements of operations and comprehensive income, (loss), shareholders' equity
and cash flows as of and for the fiscal year ended December 31, 2006 reported on

statements present fairly, in all material respects, the financial position and
results of operations and cash flows of the Borrower and its consolidated
Subsidiaries as of such dates and for such periods in accordance with GAAP.

          (b) Since December 31, 2006, nothing has occurred, either individually
or in the aggregate, which has resulted in, or would reasonably be expected to
result in, any material adverse condition or any material adverse change in or
affecting (i) the business, operations, assets, liabilities or financial
condition of the Company and its Subsidiaries, taken as a whole, or (ii) the
rights and remedies of the Lenders or the ability of the Company and each other
Account Party, taken as a whole, to perform their respective obligations to the
Lenders under this Agreement or any other Credit Document.

          SECTION 3.10. Tax Returns and Payments. Except where the failure to do
so would not reasonably be expected, individually or in aggregate, to have a
Material Adverse Effect, the Company and its Subsidiaries (i) have timely filed
or caused to be timely filed with the appropriate taxing authority (taking into
account any applicable extension within which to file) all material income and
other material tax returns (including any statements, forms and reports),
domestic and foreign, required to be filed by the Company and its Subsidiaries,
and (ii) have timely paid, collected or remitted or caused to have timely paid,
collected or remitted all material taxes payable by them which have become due
and assessments which have become due, except for those contested in good faith
and adequately disclosed and for which adequate reserves have been established
in accordance with GAAP. To the best knowledge of the Company and its
Subsidiaries, there is no action, suit, proceeding, investigation, audit or
claim now pending or proposed or threatened by any authority regarding any
income taxes or any other taxes relating to the Company or any of its
Subsidiaries, which, either individually or in the aggregate, has had, or would
reasonably be expected to have, a Material Adverse Effect. As of the Effective
Date, neither the Company nor any of its Subsidiaries has entered into an
agreement or waiver or been requested to enter into an agreement or waiver
extending any statute of limitations relating to the payment or collection of
taxes of the Company or any of its Subsidiaries. To the best knowledge of the
Company and its Subsidiaries, no tax Liens have been filed and no claims are
pending or proposed or threatened with respect to any taxes, fees or other
charges for any taxable period, except for Liens permitted under Section 6.03
and claims which, either individually or in the aggregate, have not had, and
would not reasonably be expected to have, a Material Adverse Effect.

vested) under each Foreign Pension Plan that is required to be funded,
determined as of the end of the Company's most recently ended fiscal year on the
basis of actuarial assumptions, each of which is reasonable, did not exceed the

benefit liabilities.

governmental bodies, domestic or foreign, in respect of the conduct of its
business and the ownership of its property (including compliance with all
applicable Environmental Laws), except where the failure to comply or file or
otherwise provide, either individually or in the aggregate, has not had, and
would not reasonably be expected to have, a Material Adverse Effect. All
required regulatory approvals are in full force and effect on the date hereof,
except where the failure of such approvals to be in full force and effect,
either individually or in the aggregate, has not had, and would not reasonably
be expected to have, a Material Adverse Effect.

the period provided for objection, except for those forms with respect to which
a failure to obtain such approval or make such a filing without it being

          SECTION 8.01. Appointment. Each of the Lenders hereby irrevocably
appoints each Agent as its agent and authorizes such Agent to take such actions

Subsidiaries or other Affiliate thereof as if it were not an Agent hereunder.

duties or obligations except those expressly set forth herein. Without limiting
the generality of the foregoing, (a) no Agent shall be subject to any fiduciary
or other implied duties, regardless of whether a Default has occurred and is
continuing, (b) no Agent shall have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby that such Agent is required to exercise in writing

Lenders as shall be necessary under the circumstances as provided in Section
10.02), and (c) except as expressly set forth herein, no Agent shall have any
duty to disclose, and shall not be liable for the failure to disclose, any
information relating to the Company or any of its Subsidiaries that is

Affiliates in any capacity. No Agent shall be liable for any action taken or not
taken by it with the consent or at the request of the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 10.02) or in the absence of its own gross
negligence or willful misconduct. No Agent shall be deemed to have knowledge of
any Default unless and until written notice thereof is given to such Agent by
the Company or the applicable Account Party or a Lender, and no Agent shall 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, (ii)
the contents of any certificate, report or other document delivered hereunder or
in connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein, (iv) the
validity, enforceability, effectiveness or genuineness of this Agreement or any
other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to such Agent.

          SECTION 8.04. Reliance. Each 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. Each
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. Each Agent may consult with legal counsel (who
may be counsel for the

                                       66

<PAGE>

Company), 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.

          SECTION 8.05. Delegation of Duties. Each 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 such Agent. Each Agent and any such sub-agent may
perform any and all of 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
applicable 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 Agent.

          SECTION 8.06. Resignation. Subject to the appointment and acceptance
of an applicable successor Agent as provided in this paragraph, each Agent may
resign at any time by notifying the Lenders and the Company. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor
administrative agent, syndication agent or collateral agent, as applicable, with
the consent of the Company (not to be unreasonably withheld or delayed),
provided that no such consent shall be required at any time when a Default or
Event of Default exists. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Agent gives notice of its resignation, then the retiring Agent may,
on behalf of the Lenders, appoint a successor Agent which shall be a bank with
an office in New York, New York, or an Affiliate of any such bank. Upon the
acceptance of its appointment as an Agent hereunder by a successor, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Account Parties to a successor Agent shall be the same as those payable to its
predecessor unless otherwise agreed between the Company and such successor.
After an Agent's resignation hereunder, the provisions of this Article and
Section 10.03 shall continue in effect for the benefit of such retiring Agent,
its sub-agents and their respective Related Parties in respect of any actions
taken or omitted to be taken by any of them while it was acting as an Agent.

          SECTION 8.07. Non-Reliance. Each Lender acknowledges that it has,
independently and without reliance upon any 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 any 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 related agreement or
any document furnished hereunder or thereunder.

          SECTION 8.08. Syndication Agent, Documentation Agents and Joint Lead
Arrangers and Joint Bookrunners. Notwithstanding any other provision of this
Agreement or any provision of any other Credit Document, each of the Syndication
Agent, Documentation Agents and the Joint Lead Arrangers and Joint Bookrunners
is named as such for recognition purposes only, and in its capacity as such
shall have no powers, duties, responsibilities or liabilities with

                                       67

<PAGE>

respect to this Agreement or the other Credit Documents or the transactions
contemplated hereby and thereby, except as expressly contemplated hereby.
Without limitation of the foregoing, the Syndication Agent, Documentation Agents
and the Joint Lead Arrangers and Joint Bookrunners shall not, solely by reason
of this Agreement or any other Credit Documents, have any fiduciary relationship
with any Lender or any other Person.

                                   ARTICLE IX

                                Company Guaranty

          SECTION 9.01. The Company Guaranty. In order to induce the Lenders to
enter into this Agreement and to extend credit hereunder and in recognition of
the direct benefits to be received by the Company from the issuance of the
Letters of Credit, the Company hereby agrees with the Lenders as follows: the
Company hereby unconditionally and irrevocably guarantees, as primary obligor
and not merely as surety, the full and prompt payment when due, whether upon
maturity, acceleration or otherwise, of any and all of the Guaranteed
Obligations of each Designated Subsidiary Account Party to the Guaranteed
Creditors. If any or all of the Guaranteed Obligations of any Designated
Subsidiary Account Party to the Guaranteed Creditors becomes due and payable
hereunder, the Company unconditionally promises to pay such Guaranteed
Obligations to the Guaranteed Creditors, or order, on demand, together with any
and all expenses which may be incurred by the Guaranteed Creditors in collecting
any of the Guaranteed Obligations. This Company Guaranty is a guaranty of
payment and not of collection. If a claim is ever made upon any Guaranteed
Creditor for repayment or recovery of any amount or amounts received in payment
or on account of any of the Guaranteed Obligations and any of the aforesaid
payees repays all or part of said amount by reason of (i) any judgment, decree
or order of any court or administrative body having jurisdiction over such payee
or any of its property or (ii) any settlement or compromise of any such claim
effected by such payee with any such claimant, then and in such event the
Company agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon the Company, notwithstanding any revocation of this
Company Guaranty or any other instrument evidencing any liability of each
Designated Subsidiary Account Party, and the Company shall be and remain liable
to the aforesaid payees hereunder for the amount so repaid or recovered to the
same extent as if such amount had never originally been received by any such
payee.

          SECTION 9.02. Bankruptcy. Additionally, the Company unconditionally
and irrevocably guarantees the payment of any and all of the Guaranteed
Obligations of each Designated Subsidiary Account Party hereunder to the
Guaranteed Creditors whether or not due or payable by each Designated Subsidiary
Account Party upon the occurrence of any of the events specified in Section 7.05
with respect to such Designated Subsidiary Account Party, and unconditionally
promises to pay such indebtedness to the Guaranteed Creditors, or order, on
demand, in lawful money of the United States.

          SECTION 9.03. Nature of Liability. The liability of the Company
hereunder is exclusive and independent of any security for or other guaranty of
the Guaranteed Obligations of each Designated Subsidiary Account Party whether
executed by the Company, any other guarantor or by any other party, and the
liability of the Company hereunder is not affected or impaired by (a) any
direction as to application of payment by each Designated

                                       68

<PAGE>

Subsidiary Account Party or by any other party (other than a direction by the
Guaranteed Creditor receiving such payment), or (b) any other continuing or
other guaranty, undertaking or maximum liability of a guarantor or of any other
party as to the Guaranteed Obligations of each Designated Subsidiary Account
Party, or (c) any payment on or in reduction of any such other guaranty or
undertaking, or (d) any dissolution, termination or increase, decrease or change
in personnel by each Designated Subsidiary Account Party, or (e) any payment
made to the Guaranteed Creditors on the Guaranteed Obligations which any such
Guaranteed Creditor repays to each Designated Subsidiary Account Party pursuant
to court order in any bankruptcy, reorganization, arrangement, moratorium or
other debtor relief proceeding, and the Company waives any right to the deferral
or modification of its obligations hereunder by reason of any such proceeding or
(f) any action or inaction of the type described in Section 9.05.

          SECTION 9.04. Independent Obligation. The obligations of the Company
under this Article IX are independent of the obligations of any other guarantor,
any other party or each Designated Subsidiary Account Party, and a separate
action or actions may be brought and prosecuted against the Company whether or
not action is brought against any other guarantor, any other party or each
Designated Subsidiary Account Party and whether or not any other guarantor, any
other party or each Designated Subsidiary Account Party be joined in any such
action or actions. The Company waives, to the full extent permitted by law, the
benefit of any statute of limitations affecting its liability under this Article
IX or the enforcement thereof. Any payment by a Designated Subsidiary Account
Party or other circumstance which operates to toll any statute of limitations as
to a Designated Subsidiary Account Party shall operate to toll the statute of
limitations as to the Company.

          SECTION 9.05. Authorization. The obligations of the Company under this
Article IX shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by any action taken by any Guaranteed Creditor to:

          (a) change the manner, place or terms of payment of, and/or change or
extend the time of payment of, renew, increase, accelerate or alter, any of the
Guaranteed Obligations (including any increase or decrease in the rate of
interest thereon), any security therefor, or any liability incurred directly or
indirectly in respect thereof, and the guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;

          (b) take and hold security for the payment of the Guaranteed
Obligations and sell, exchange, release, impair, surrender, realize upon or
otherwise deal with in any manner and in any order any property by whomsoever at
any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
Obligations or any liabilities (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and/or any offset
thereagainst;

          (c) exercise or refrain from exercising any rights against any
Designated Subsidiary Account Party or others or otherwise act or refrain from
acting;

          (d) release or substitute any one or more endorsers, guarantors, any
Designated Subsidiary Account Party or other obligor;

                                       69

<PAGE>

          (e) settle or compromise any of the Guaranteed Obligations, any
security therefor or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and may subordinate the
payment of all or any part thereof to the payment of any liability (whether due
or not) of any Designated Subsidiary Account Party to its creditors other than
the Guaranteed Creditors;

          (f) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of any Designated Subsidiary Account Party to the
Guaranteed Creditors regardless of what liability or liabilities of any
Designated Subsidiary Account Party remain unpaid;

          (g) consent to or waive any breach of, or any act, omission or default
under, this Agreement or any other Credit Document or any of the instruments or
agreements referred to herein or therein, or otherwise amend, modify or
supplement this Agreement, any other Credit Document or any of such other
instruments or agreements; and/or

          (h) take any other action which would, under otherwise applicable
principles of common law, give rise to a legal or equitable discharge of the
Company from its liabilities under this Company Guaranty.

          SECTION 9.06. Reliance. It is not necessary for the Guaranteed
Creditors to inquire into the capacity or powers of any Designated Subsidiary
Account Party or the officers, directors, partners or agents acting or
purporting to act on their behalf, and any Guaranteed Obligations made or
created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

          SECTION 9.07. Subordination. Any indebtedness of any Designated
Subsidiary Account Party now or hereafter owing to the Company is hereby
subordinated to the Guaranteed Obligations of each Designated Subsidiary Account
Party owing to the Guaranteed Creditors; and if the Administrative Agent so
requests at a time when an Event of Default exists, no Designated Subsidiary
Account Party shall make, or be permitted to make, any payment to the Company in
respect of such indebtedness owed to the Company, but without affecting or
impairing in any manner the liability of the Company under the other provisions
of this Company Guaranty. Prior to the transfer by the Company of any note or
negotiable instrument evidencing any of the indebtedness of any Designated
Subsidiary Account Party to the Company, the Company shall mark such note or
negotiable instrument with a legend that the same is subject to this
subordination. Without limiting the generality of the foregoing, the Company
hereby agrees with the Guaranteed Creditors that it will not exercise any right
of subrogation which it may at any time otherwise have as a result of this
Company Guaranty (whether contractual, under Section 509 of the Bankruptcy Code
or otherwise) until all Guaranteed Obligations have been irrevocably paid in
full in cash.

          SECTION 9.08. Waiver. (a) The Company waives any right (except as
shall be required by applicable statute and cannot be waived) to require any
Guaranteed Creditor to (i) proceed against any Designated Subsidiary Account
Party, any other guarantor or any other party, (ii) proceed against or exhaust
any security held from any Designated Subsidiary Account Party, any other
guarantor or any other party or (iii) pursue any other remedy in any Guaranteed
Creditor's power whatsoever. The Company waives any defense based on or arising
out of any

                                       70

<PAGE>

defense of any Designated Subsidiary Account Party, any other guarantor or any
other party, other than payment in full of the Guaranteed Obligations, based on
or arising out of the disability of any Designated Subsidiary Account Party, any
other guarantor or any other party, or the unenforceability of the Guaranteed
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of any Designated Subsidiary Account Party other than payment
in full of the Guaranteed Obligations. The Guaranteed Creditors may, at their
election, foreclose on any security held by the Administrative Agent or any
other Guaranteed Creditor by one or more judicial or non-judicial sales, whether
or not every aspect of any such sale is commercially reasonable (to the extent
such sale is permitted by applicable law), or exercise any other right or remedy
the Guaranteed Creditors may have against any Designated Subsidiary Account
Party or any other party, or any security, without affecting or impairing in any
way the liability of the Company hereunder except to the extent the Guaranteed
Obligations have been paid. The Company waives any defense arising out of any
such election by the Guaranteed Creditors, even though such election operates to
impair or extinguish any right of reimbursement or subrogation or other right or
remedy of the Company against any Designated Subsidiary Account Party or any
other party or any security.

          (b) The Company waives all presentments, demands for performance,
protests and notices, including notices of non-performance, notices of protest,
notices of dishonor, notices of acceptance of this Company Guaranty, and notices
of the existence, creation or incurring of new or additional Guaranteed
Obligations. The Company assumes all responsibility for being and keeping itself
informed of each Designated Subsidiary Account Party's financial condition and
assets, and of all other circumstances bearing upon the risk of non-payment of
the Guaranteed Obligations and the nature, scope and extent of the risks which
the Company assumes and incurs hereunder, and agrees that the Guaranteed
Creditors shall have no duty to advise the Company of information known to them
regarding such circumstances or risks.

          (c) The Company warrants and agrees that each of the waivers set forth
above in this Section 9.08 is made with full knowledge of its significance and
consequences, and such waivers shall be effective to the maximum extent
permitted by law.

     specified opposite its signature below;

          (iii) if to the Administrative Agent, to JPMorgan Chase Bank, National

     erin.orourke@jpmorgan.com); and

          (iv) if to any other Lender, to it at its address (or facsimile
     number) set forth in its Administrative Questionnaire.

          (b) Notices and other communications to the Lenders hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent; provided that the foregoing shall not
apply to notices pursuant to (x) Article II unless otherwise agreed by the
Administrative Agent and the applicable Lender or (y) Section 5.01(e)(x). The
Administrative Agent or the Company may, in its discretion, agree to accept
notices and other communications to it hereunder by electronic communications
pursuant to procedures approved by it; provided that approval of such procedures
may be limited to particular notices or communications.

          (c) Any party hereto may change its address or facsimile number for
notices and other communications hereunder by notice to the other parties
hereto. 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 failure or delay by the
Administrative Agent 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 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 Account Party
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section 10.02, 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 issuance of any Letter of
Credit shall not be construed as a waiver of any Default, regardless of whether
the Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time. In the case of any waiver, each Account Party, the
Administrative Agent and the Lenders shall be restored to their former positions
and rights hereunder and any Default or Event of Default so waived shall be
deemed to be cured and not continuing. No such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon.

          (b) Neither this Agreement, any other Credit Document nor any
provision hereof or thereof may be waived, amended or modified except pursuant
to an agreement or

                                       72

<PAGE>

agreements in writing entered into by each Account Party and the Required
Lenders or by each Account Party and the Administrative Agent with the consent
of the Required Lenders; provided that no such agreement shall (i) increase the
Commitment of any Lender without the written consent of such Lender, (ii) reduce
the amount of any amount due pursuant to any Letter of Credit or Unpaid Drawing
or reduce any interest or fees payable hereunder, without the written consent of
each Lender affected thereby, (iii) postpone the scheduled date for
reimbursement of any Unpaid Drawing, 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 the Commitments or any Letter of
Credit, without the written consent of each Lender affected thereby, (iv) change
Section 2.13(b) or (c) in a manner that would alter the pro rata sharing of
payments required thereby or change any of the provisions of this Section 10.02
or 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, (v) release all or a substantial
portion of the Collateral (except as expressly provided in the Credit Documents)
under all the Security Documents, change in any material respect the definition
of "Advance Rate" or "Borrowing Base", change in any material respect any
provision of Section 2.10 or 2.16(b)(ii) or release the Company from the Company
Guaranty (or change the Company Guaranty in a manner that is materially adverse
to the Lenders), without the written consent of each Lender or (vi) change any
provision of Article II without the written consent of each LC Issuer affected
thereby; and provided, further, that no such agreement shall amend, modify or
otherwise affect the rights or duties of any Agent or any LC Issuer hereunder
without the prior written consent of such Agent or such LC Issuer, as the case
may be. Notwithstanding the foregoing or any other provision of this Agreement,
any provision of this Agreement may be amended by an agreement in writing
entered into by the Company, the Super-Majority Lenders and the Administrative
Agent (and, if its rights or obligations are affected thereby, each LC Issuer
and the Issuing Agent) if (x) by the terms of such agreement the Commitment of
each Lender not consenting to the amendment provided for therein shall
terminate, and any Several Letters of Credit then outstanding shall either be
terminated, amended or returned and reissued, in each case to give effect to
such termination (it being understood that the Company may cause the Commitment
of any such non-consenting Lender to be assigned to one or more new Lenders in
accordance with Section 10.04; provided that no action shall be required to be
taken by such non-consenting Lender (including the execution of any Assignment
and Assumption Agreement)) and (y) at the time such amendment becomes effective,
each Lender not consenting thereto receives payment in full of all amounts owing
to it or accrued for its account under this Agreement.

          SECTION 10.03. Expenses; Indemnity; Damage Waiver. (a) Each Account
Party jointly and severally agrees to pay (i) all out-of-pocket expenses
incurred by the Agents, the Joint Lead Arrangers and Joint Bookrunners and their
Affiliates, including the reasonable fees, charges and disbursements of counsel,
in connection with the syndication of the credit facility provided for herein,
the preparation and administration of this Agreement or any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions contemplated hereby or thereby shall be consummated) or protection
of its rights hereunder or thereunder, and (ii) all out-of-pocket expenses
incurred by any Agent, any Joint Lead Arranger and Joint Bookrunner or any
Lender, including the reasonable fees, charges and disbursements of one primary
counsel and all applicable foreign counsel thereto, in connection with the

                                       73

<PAGE>

enforcement of its rights in connection with this Agreement or the other Credit
Documents, including its rights under this Section, or in connection with the
Letters of Credit issued hereunder, including all such out-of-pocket expenses
incurred during any workout, restructuring or negotiations in respect of such
Letters of Credit.

          (b) Each Account Party jointly and severally agrees to indemnify the
Agents, the Joint Lead Arrangers and Joint Bookrunners and each Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and 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 any other transactions contemplated hereby,
(ii) any Letter of Credit or the use of the proceeds therefrom, (iii) any actual
or alleged presence or release of Hazardous Materials on or from any property
owned or operated by the Company or any of its Subsidiaries, or any
Environmental Liability related in any way to the Company or any of its
Subsidiaries, 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
or whether such claim, litigation, investigation or proceeding is brought by the
Company or any of its Subsidiaries or a third party; provided that such
indemnity shall not, as to any Indemnitee or any Related Party of such
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 non-appealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee or any Related Party
of such Indemnitee.

          (c) To the extent that any Account Party fails to pay any amount
required to be paid by it to an Agent, under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to such Agent 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 such Agent, in its capacity as such.

          (d) To the extent permitted by applicable law, no Account Party shall
assert, and each Account Party 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, any Letter of Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section shall be payable promptly after
written demand therefor.

          SECTION 10.04. Successors and Assigns. (a) 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 except that (i) no
Account Party may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent

                                       74

<PAGE>

of each Lender (and any attempted assignment or transfer by such Account Party
without such consent shall be null and void) and (ii) no Lender may assign or
otherwise transfer its rights or obligations hereunder except in accordance with
this Section. 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, 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 Agents and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

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

               (A) the Company, provided that no consent of the Company shall be
          required for an assignment to a Lender, an Affiliate of a Lender, an
          Approved Fund or, if an Event of Default has occurred and is
          continuing, any other assignee; and

               (B) the Administrative Agent and each LC Issuer.

          (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, the amount of the Commitment 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 Company and the Administrative Agent
          otherwise consent, provided that no such consent of the Company 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;

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

               (E) the assignee shall be an NAIC Approved Bank that is not a
          parent, subsidiary or Affiliate of any Account Party or any
          beneficiary under any Letter of Credit; and

                                       75

<PAGE>

               (F) if any Several Letters of Credit are then outstanding, no
          such assignment shall be effective until all such outstanding Several
          Letters of Credit are either amended or returned and reissued, in each
          case to give effect to such assignment.

          For the purposes of this Section 10.04(b), the term "Approved Fund"
has the following meaning:

          "Approved Fund" means any Person (other than a natural person) that is
engaged in making, purchasing, holding or investing in bank loans and similar
extensions of credit in the ordinary course of its business and that is
administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an
entity or an Affiliate of an entity that administers or manages a Lender.

          (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 (provided that any liability of any Account Party to
     such assignee under Section 2.06 or 2.12 shall be limited to the amount, if
     any, that would have been payable thereunder by such Account Party in the
     absence of such assignment, except to the extent any such amounts are
     attributable to a Change in Law), 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 2.06, 2.12 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.

          (iv) The Administrative Agent, acting for this purpose as an agent of
     the Account Parties, shall maintain at one of its offices 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 each Lender pursuant to the terms hereof from time to time (the
     "Register"). The entries in the Register shall be conclusive absent
     manifest error, and the Account Parties, the Administrative Agent 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 Account Parties, and any Lender, at any
     reasonable time and from time to time upon reasonable prior notice.

          (v) 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

                                       76

<PAGE>

     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.

          (c) (i) Any Lender may, without the consent of any Account Party or
the Administrative Agent, 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 (including all or a portion of its Commitment
and Unpaid Drawings owing to it); provided that (A) such Lender's obligations
under this Agreement shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (C) the Account Parties, the Administrative Agent 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. 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 to
approve any amendment, modification or waiver of any provision of this
Agreement; 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
affects such Participant. Subject to paragraph (c)(ii) of this Section, each
Account Party agrees that each Participant shall be entitled to the benefits of
Sections 2.06 and 2.12 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 2.13(c) as though it were a Lender.

          (ii) A Participant shall not be entitled to receive any greater
     payment under Section 2.06 or 2.12 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 Company's prior written consent and the entitlement to
     greater payment results solely from a Change in Law. A Participant that
     would be a Foreign Lender if it were a Lender shall not be entitled to the
     benefits of Section 2.12 unless the Company is notified of the
     participation sold to such Participant and such Participant agrees, for the
     benefit of the Account Parties, to comply with Section 2.12(e) as though it
     were a Lender.

          (d) 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 pledge or assignment to secure obligations 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 any Account Party 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

                                       77

<PAGE>

Agreement and the 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 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 any
Letter of Credit is outstanding, any fee or any other amount payable under this
Agreement is outstanding and unpaid and so long as the Total Commitment (and the
Commitment of each Lender) has not expired or terminated. The provisions of
Sections 2.06, 2.12 and 10.03 and Article VIII shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated
hereby, the expiration or termination of the Total Commitment (and the
Commitment of each Lender) or the termination of this Agreement or any provision
hereof.

          SECTION 10.06. Counterparts; Integration; Effectiveness. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall 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 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. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by facsimile 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 of its Affiliates 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) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of any
Account Party against any of and all the obligations of such Account Party now
or hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 10.09. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

                                       78

<PAGE>

          (b) Each party hereto hereby irrevocably and unconditionally submits,
for itself and its property, to the exclusive 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 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 or any Lender may otherwise have
to bring any action or proceeding relating to this Agreement against any Account
Party or its properties in the courts of any jurisdiction.

          (c) Each party hereto 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) Each party to this Agreement irrevocably consents to service of
process in connection with disputes arising out of this Agreement or any other
Credit Document 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.

          (e) Each Account Party hereby irrevocably designates, appoints and
empowers the Service of Process Agent, with offices on the date hereof at 111
Eighth Avenue, New York, New York 10011, as its designee, appointee and agent to
receive, accept and acknowledge for and on its behalf, and in respect of its
property, service of any and all legal process, summons, notices and documents
which may be served in any such action or proceeding. If for any reason such
designee, appointee and agent shall cease to be available to act as such, each
Account Party agrees to designate a new designee, appointee and agent in New
York City on the terms and for the purposes of this provision reasonably
satisfactory to the Administrative Agent under this Agreement.

          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

                                       79

<PAGE>

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. Confidentiality. Each of the Agents and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that (i) 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 in accordance
with the terms of this Agreement and (ii) that the applicable Agent or Lender
shall be responsible for any breach of this Section 10.12 by any of its and its
Affiliates' directors, officers, employees and agents, including accountants,
legal counsel and other advisors), (b) to the extent requested by any regulatory
authority or self-regulatory body, (c) to the extent required by applicable laws
or regulations or by any subpoena or similar legal process, (d) to any other
party to this Agreement, (e) in connection with the exercise of any remedies
hereunder or any suit, action or proceeding relating to this Agreement or the
enforcement of rights hereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section, to (i) any assignee
of or Participant in, or any prospective assignee of or Participant in, any of
its rights or obligations under this Agreement or (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
any Account Party and its obligations, (g) with the consent of the Company or
(h) to the extent such Information (i) becomes publicly available other than as
a result of a breach of this Section or (ii) becomes available to any Agent or
any Lender on a non-confidential basis from a source other than the Company
that, to the applicable Agent's or Lender's knowledge, is not subject to a
confidentiality undertaking with respect to the applicable Information. For the
purposes of this Section, "Information" means all information now or hereafter
received from any Account Party relating to the Company, any Subsidiary of the
Company or their respective businesses, other than any such information that is
available to any Agent or any Lender on a non-confidential basis prior to
disclosure by any Account Party. 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 or, in the case of any
Lender, such Lender has treated such Information in a manner consistent with
banking industry standards for the treatment of confidential information. The
provisions of this Section 10.12 shall survive the termination of the Total
Commitment (and the Commitment of each Lender) and the other obligations arising
hereunder, but such survival shall only be for a period of two (2) years
following the Commitment Expiration Date.

          SECTION 10.13. Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any
Unpaid Drawings, together with all fees, charges and other amounts which are
treated as interest on such amount or pursuant to any Letter of Credit under
applicable law (collectively the "Charges"), shall exceed the maximum lawful
rate (the "Maximum Rate") which may be contracted for, charged, taken,

                                       80

<PAGE>

received or reserved by the Lender issuing or holding participation in such
Letter of Credit in accordance with applicable law, the rate of interest payable
in respect of such Letter of Credit hereunder, together with all Charges payable
in respect thereof, shall be limited to the Maximum Rate and, to the extent
lawful, the interest and Charges that would have been payable in respect of such
Letter of Credit but were not payable as a result of the operation of this
Section shall be cumulated and the interest and Charges payable to such Lender
in respect of other Letters of Credit or periods shall be increased (but not
above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment,
shall have been received by such Lender.

          SECTION 10.14. USA Patriot Act. Each Lender hereby notifies the
Company and each other Account Party that pursuant to the requirements of the
USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001))
(the "Patriot Act"), it is required to obtain, verify and record information
that identifies each Account Party, which information includes the name and
address of each Account Party and other information that will allow such Lender
to identify each Account Party in accordance with the Patriot Act.

          SECTION 10.15. Termination of Existing LC Facility. JPMorgan Chase
Bank, National Association, in its capacity as Existing Administrative Agent,
and Bank of New York, in its capacity as Existing Collateral Agent, hereby
agree, acknowledge and confirm that upon the effectiveness of this Agreement on
the Effective Date and payment in full of any and all principal, interest, fees
and other amounts owing under or in connection with the Existing LC Facility (as
specified by the Existing Administrative Agent to the Company on or prior to the
Effective Date), all liabilities, obligations and indebtedness owing by the
Company and the Account Parties under the Existing LC Facility and the Credit
Documents as defined therein shall be automatically released, discharged and

Collateral Agent for the benefit of the Secured Creditors (as defined in the
Security Agreement referenced in the Existing LC Facility) in any property of
the Company or its Subsidiaries pursuant to the Credit Documents (as defined in
the Existing LC Facility) shall be automatically released and terminated and the
Existing LC Facility, the other Credit Documents as defined therein and all
related instruments, agreements and other documents shall be automatically
terminated (provided that any contingent and/or indemnity obligations under the
Existing LC Facility and such Credit Documents which expressly survive
termination thereof shall continue to remain in effect in accordance therewith).

                            Letters of Credit; Loans

          SECTION 2.01. Several Letters of Credit. (a) Subject to and upon the
terms and conditions set forth herein, each Account Party may request the
Issuing Agent, at any time and from time to time on or after the Effective Date
and prior to the Commitment Expiration Date, to issue, on behalf of each Lender,
for the account of such Account Party and in support of, on a standby basis,
Letter of Credit Supportable Obligations of such Account Party to any other
Person, and subject to and upon the terms and conditions herein set forth, the
Issuing Agent agrees to issue at any time and from time to time on or after the
Effective Date and prior to the Commitment Expiration Date one or more
irrevocable standby letters of credit denominated in Dollars and in such form as
may be approved by the Issuing Agent which approval shall not be unreasonably
withheld or delayed (each such letter of credit, a "Several Letter of Credit"
and, collectively, the "Several Letters of Credit"). Subject to the terms and
conditions hereof and any other instruments and documents contemplated hereby,
it is the intent of the parties hereto that all Letters of Credit shall be clean
and irrevocable and otherwise in a form sufficient for the beneficiary cedent to
take credit on its financial statements for reinsurance recoverables under
applicable rules, laws and regulations.

          (b) Each Several Letter of Credit will be issued by the Issuing Agent
on behalf of the Lenders and each Lender will participate in each Several Letter
of Credit pro rata in accordance with its Applicable Percentage. The obligations
of each Lender under and in respect of each Several Letter of Credit are
several, and the failure by any Lender to perform its obligations hereunder or
under any Letter of Credit shall not affect the obligations of the respective
Account Party toward any other party hereto nor shall any other such party be
liable for the failure by such Lender to perform its obligations hereunder or
under any Several Letter of Credit.

          (c) Each Several Letter of Credit shall be executed and delivered by
the Issuing Agent in the name and on behalf of, and as attorney-in-fact for,
each Lender and the Issuing Agent shall act under each Several Letter of Credit,
and each Several Letter of Credit shall expressly provide that the Issuing Agent
shall act, as the agent of each Lender, to (a) receive drafts, other demands for
payment and other documents presented by the beneficiary under such Several
Letter of Credit, (b) determine whether such drafts, demands and documents are
in compliance with the terms and conditions of such Letter of Credit and (c)
notify such Lender and such Account Party that a valid drawing has been made and
the date that the related Several Unpaid Drawing is to be made; provided that
the Issuing Agent shall have no obligation or liability for any Several Unpaid
Drawing under such Letter of Credit, and each Several Letter of Credit shall
expressly so provide. Each Lender hereby irrevocably appoints and designates the
Issuing Agent as its attorney-in-fact, acting through any duly authorized
officer of the Issuing Agent, to execute and deliver in the name and on behalf
of such Lender each Several Letter of

                                       22

<PAGE>

Credit to be issued by such Lender hereunder. Promptly upon the request of the
Issuing Agent, each Lender will furnish to the Issuing Agent such powers of
attorney or other evidence as any beneficiary of any Several Letter of Credit
may reasonably request in order to demonstrate that the Issuing Agent has the
power to act as attorney-in-fact for such Lender to execute and deliver such
Several Letter of Credit.

          (d) Each Lender represents and warrants that each Several Letter of
Credit constitutes a legal, valid and binding obligation of such Lender
enforceable in accordance with its terms, provided that the enforceability
thereof is subject to general principles of equity and to bankruptcy, insolvency
and similar laws affecting the enforcement of creditors' rights generally.

          SECTION 2.02. Fronted Letters of Credit. (a) Subject to and upon the
terms and conditions set forth herein, each Account Party may request that any
Fronting Lender at any time and from time to time on or after the Effective Date
and prior to the Commitment Expiration Date issue for its own account a letter
of credit denominated in Dollars for the account of such Account Party and in
support of, on a standby basis, Letter of Credit Supportable Obligations of such
Account Party to any other Person, and subject to and upon the terms and
conditions herein set forth, each Fronting Lender agrees to issue at any time
and from time to time on or after the Effective Date and prior to the Commitment
Expiration Date one or more irrevocable standby letters of credit in such form
as may be approved by such Fronting Lender, which approval shall not be
unreasonably withheld or delayed (each such letter of credit, a "Fronted Letter
of Credit" and, collectively, the "Fronted Letters of Credit"). Subject to the
terms and conditions hereof and any other instruments and documents contemplated
hereby, it is the intent of the parties hereto that all Letters of Credit shall
be clean and irrevocable and otherwise in a form sufficient for the beneficiary
cedent to take credit on its financial statements for reinsurance recoverables
under applicable rules, laws and regulations.

          (b) Immediately upon the issuance by any Fronting Lender of any
Fronted Letter of Credit, such Fronting Lender shall be deemed to have sold and
transferred to each Lender other than such Fronting Lender (each such Lender, in
its capacity under this Section 2.02(b), a "Fronting Participant"), and each
such Fronting Participant shall be deemed irrevocably and unconditionally to
have purchased and received from such Fronting Lender, without recourse or
warranty, an undivided interest and participation, to the extent of such
Fronting Participant's Applicable Percentage, in such Fronted Letter of Credit,
each drawing made thereunder and the obligations of each Account Party under
this Agreement with respect thereto, and any security therefor or guaranty
pertaining thereto. Upon any change in the Commitments or Applicable Percentages
of the Lenders pursuant to this Agreement, it is hereby agreed that, with
respect to all outstanding Fronted Letters of Credit and Fronted Unpaid
Drawings, there shall be an automatic adjustment to the participations pursuant
to this Section 2.02 to reflect the new Applicable Percentages of the assignor
and assignee Lender or of all Lenders with Commitments, as the case may be.

          (c) In the event that any Fronting Lender makes any payment under any
Fronted Letter of Credit and the respective Account Party shall not have
reimbursed such amount in full to such Fronting Lender pursuant to Section 2.05,
such Fronting Lender shall promptly notify the Administrative Agent, which shall
promptly notify each Fronting Participant, of such failure, and each Fronting
Participant shall promptly and unconditionally pay to such Fronting

                                       23

<PAGE>

Lender the amount of such Fronting Participant's Applicable Percentage of such
unreimbursed payment in Dollars and in immediately available funds. If, prior to
11:00 a.m. (New York time) on any Business Day, the Administrative Agent so
notifies any Fronting Participant required to fund a payment under a Fronted
Letter of Credit, such Fronting Participant shall make available to such
Fronting Lender in Dollars and in immediately available funds such Fronting
Participant's Applicable Percentage of the amount of such payment on such
Business Day (or, if notice is given after 11:00 a.m. (New York time) on any
Business Day, on the next Business Day). If and to the extent such Fronting
Participant shall not have so made its Applicable Percentage of the amount of
such payment available to such Fronting Lender, such Fronting Participant agrees
to pay to such Fronting Lender, forthwith on demand, such amount, together with
interest thereon, for each day from such date to but excluding the date such
amount is paid to such Fronting Lender at the overnight Federal Funds Effective
Rate. The failure of any Fronting Participant to make available to such Fronting
Lender its Applicable Percentage of any payment under any Fronted Letter of
Credit shall not relieve any other Fronting Participant of its obligation
hereunder to make available to such Fronting Lender its Applicable Percentage of
any payment on the date required, as specified above, but no Fronting
Participant shall be responsible for the failure of any other Fronting
Participant to make available to such Fronting Lender such other Fronting
Participant's Applicable Percentage of any such payment.

          (d) Whenever any Fronting Lender receives any payment by any Account
Party as to which it has also received payments from the Fronting Participants
pursuant to paragraph (c) above, such Fronting Lender shall forward such payment
to the Administrative Agent, which in turn shall distribute to each Fronting
Participant which has paid its Applicable Percentage thereof, in Dollars and in
immediately available funds, an amount equal to such Fronting Participant's
share (based upon the amount funded by such Fronting Participant to the
aggregate amount funded by all Fronting Participants and retained by the
Fronting Lender) of the principal amount of such payment and interest thereon
accruing after the purchase of the respective participations.

          (e) The obligations of the Fronting Participants to make payments to
each Fronting Lender with respect to Fronted Letters of Credit issued by it
shall be irrevocable and not subject to any qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances, including any of the following circumstances:

               (i) any lack of validity or enforceability of this Agreement or
          any amendment, supplement or modification hereof;

               (ii) the existence of any claim, setoff, defense or other right
          which the Fronting Participant or any of its Affiliates may have at
          any time against a beneficiary named in a Fronted Letter of Credit,
          any transferee of any Fronted Letter of Credit (or any Person for whom
          any such transferee may be acting), the Administrative Agent, any
          Fronting Lender, any Fronting Participant, any Lender, or any other
          Person, whether in connection with this Agreement, any Fronted Letter
          of Credit, the transactions contemplated herein or any unrelated
          transactions (including any underlying transaction between any Account
          Party or

                                       24

<PAGE>

          any of its Affiliates and the beneficiary named in any such Fronted
          Letter of Credit);

               (iii) any draft, certificate or any other document presented
          under any Fronted Letter of Credit proving to be forged, fraudulent,
          invalid or insufficient in any respect or any statement therein being
          untrue or inaccurate in any respect;

               (iv) the surrender or impairment of any security for the
          performance or observance of any of the terms of this Agreement;

               (v) the occurrence of any Default or Event of Default; or

               (vi) any matter or event set forth in Section 2.05(b).

          (f) Upon the request of any Fronting Participant, each Fronting Lender
shall furnish to such Fronting Participant copies of any Fronted Letter of
Credit issued by it and such other documentation as may reasonably be requested
by such Fronting Participant.

          SECTION 2.03. Conditions to the Issuance of all Letters of Credit. (a)

     Issuer or any Lenders refrain from, the issuance of letters of credit
     generally or the applicable type of letter of credit or shall impose upon
     such LC Issuer or any Lender with respect to the applicable type of letter
     of credit any restriction or reserve or capital requirement (for which such
     LC Issuer or such Lender is not otherwise compensated) not in effect on the
     Effective Date, or any unreimbursed loss, cost or expense which was not
     applicable, in effect or known to such LC Issuer, as of the Effective Date;

          (ii) the conditions precedent set forth in Section 4.02 are not
     satisfied at that time; or

     giving effect to such issuance exceed) the maximum aggregate Stated Amount
     of all Fronted Letters of Credit that such Fronting Lender has agreed to
     issue in a separate agreement with the Company, if any;

          (iii) each Letter of Credit shall have an expiry date occurring not
     later than one year after such Letter of Credit's date of issuance,
     provided that, subject to Section 2.07, each such Letter of Credit may by
     its terms automatically renew annually for additional one-year periods
     unless the respective LC Issuer notifies the beneficiary thereof, in
     accordance with the terms of such Letter of Credit, that such Letter of
     Credit will not be renewed; and

          (iv) no LC Issuer will issue any Letter of Credit after it has
     received written notice from any Account Party or the Required Lenders
     stating that a Default or an Event of Default exists until such time as the
     Issuing Agent shall have received a written notice of (x) rescission of
     such notice from the party or parties originally delivering the same or (y)
     a waiver of such Default or Event of Default by the Required Lenders (or
     such other number or percentage of the Lenders as shall be necessary under

Request"). Each Letter of Credit Request shall include any other documents as
the respective LC Issuer customarily and generally requires in connection
therewith, provided that in the case where JPMorgan Chase Bank, National
Association, The Bank of Nova Scotia, Deutsche Bank AG New York Branch or any of
their respective affiliates is the LC Issuer, such additional documentation
shall be limited to those set forth in Exhibit I hereto (or such other documents
as may be reasonably acceptable to both the Company and the applicable LC

or disbursed by such Lender, to the extent not reimbursed prior to 1:00 p.m.

defense to payment which such Account Party may have or have had against such
Lender, or any LC Issuer, including any defense based upon the failure of any
drawing under a Letter of Credit to conform to the terms of the Letter of Credit
or any non-application or misapplication by the beneficiary of the proceeds of

of Credit as a result of acts or omissions constituting willful misconduct or
gross negligence on the part of such Lender (as determined by a court of
competent jurisdiction in a final and non-appealable judgment).

Issuer shall have any obligation relative to the other Lenders other than to
confirm that any documents required to be delivered under such Letter of Credit
appear to have been delivered and that they appear to substantially comply on
their face with the requirements of such Letter of Credit. Any action taken or
omitted to be taken by any LC Issuer under or in connection with any Letter of
Credit, if taken or omitted in the absence of such LC Issuer's gross negligence
or willful misconduct (as determined by a court of competent jurisdiction in a
final and non-appealable judgment), shall not create for such LC Issuer any
resulting liability to any Account Party or any of its Affiliates or any Lender.

          SECTION 2.06. Increased Costs. If a Change in Law shall either (i)
impose, modify or make applicable any reserve, deposit, capital adequacy or
similar requirement against letters of credit issued by or participated in,
assets of, deposits with or for the account of, or credit extended by, such
Lender (except any such reserve requirement reflected in the Adjusted LIBO
Rate), or (ii) impose on such Lender or the London interbank market any other
conditions directly or indirectly affecting this Agreement, any Letter of Credit
or Eurodollar Loans made by such Lender; and the result of any of the foregoing
is to (A) increase the cost to such Lender of (1) issuing, maintaining or
participating in any Letter of Credit or (2) making or maintaining any
Eurodollar Loan (or of maintaining its obligation to make any such Loan), (B)
reduce the amount of any sum received or receivable by such Lender hereunder
(whether of principal, interest or otherwise) or (C) reduce the rate of return
on its capital with respect to Letters of Credit and/or the Loans to a level
below that which such Lender would have achieved but for such Change in Law (and
taking into consideration such Lender's policies with respect to capital
adequacy (or those of its holding company), as generally applied), then, upon
written demand to the applicable Account Party by such Lender (with a copy to
the Administrative Agent), such Account Party shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such increased
cost or reduction. The preceding sentence shall not apply to increased costs
with respect to taxes imposed on or measured by the net income or net profits of
a Lender pursuant to the laws of the jurisdiction in or under the laws of which
it is organized or the jurisdiction in which the principal office or applicable
lending office of such Lender is located or in which it conducts a trade or
business or has a permanent establishment, or has a present or former connection
with such jurisdiction, or any subdivision thereof or therein or with respect to
Taxes to the extent that a Lender received additional amounts (or otherwise was
indemnified) for such Taxes pursuant to Section 2.12 (or would have received
additional amounts pursuant to Section 2.12(e) but for a failure to comply with
Section 2.12(e)). A certificate submitted to the applicable Account Party by
such Lender (with a copy to the Administrative Agent), setting forth (i) the
basis, in reasonable detail, for the determination of such additional amount or
amounts necessary to compensate such Lender as aforesaid and (ii) the basis, in
reasonable detail, for the computation of such amount or amounts, which shall be
consistently applied shall be final and conclusive and binding on the applicable
Account Party absent manifest error, although the failure to deliver any such
certificate shall not release or diminish such Account Party's obligations to
pay additional amounts pursuant to this Section 2.06 upon subsequent receipt of
such certificate. Notwithstanding the foregoing, no Account Party shall be
required to compensate any Lender pursuant to this Section 2.06 for any
increased costs or reductions incurred more than 180 days prior to the date that
such Lender notifies such Account Party of the applicable Change in Law;
provided that if the Change in Law

                                       28

<PAGE>

giving rise to such increased costs or reductions is retroactive, then such
180-day period referred to above shall be extended to include the period of
retroactive effect thereof.

          SECTION 2.07. Letter of Credit Expiration and Extensions. Each Lender
acknowledges that to the extent provided under the terms of any Letter of
Credit, the expiration date of such Letter of Credit will be automatically
extended for additional one-year periods, without written amendment, unless (a)
at least 30 days (or such other period required under or by any Legal
Requirement or Applicable Insurance Regulatory Authority) prior to the
expiration date of such Letter of Credit or (b) such extension would cause such
Letter of Credit to remain outstanding on or after the one-year anniversary of
the Commitment Expiration Date, notice is given by the respective LC Issuer in
accordance with the terms of the respective Letter of Credit (a "Notice of
Non-Extension") that the expiration date of such Letter of Credit will not be
extended beyond its current expiration date. The respective LC Issuer will give
Notices of Non-Extension as to any or all outstanding Letters of Credit if
requested to do so by the Required Lenders pursuant to Article VII. The
respective LC Issuer will give Notices of Non-Extension as to all outstanding
Letters of Credit (i) if the Commitment Expiration Date has occurred and (ii) on
the date necessary to prevent the extension described in the foregoing clause
(b). The respective LC Issuer will send a copy of each Notice of Non-Extension
to the respective Account Party concurrently with delivery thereof to the
respective beneficiary, unless prohibited by law from doing so.

          SECTION 2.08. Changes to Stated Amount. At any time when any Letter of
Credit is outstanding, at the request of the respective Account Party, the
Issuing Agent will enter into an amendment increasing or reducing the Stated
Amount of such Letter of Credit, provided that (i) in no event shall the Stated
Amount of such Letter of Credit be increased to an amount which would cause (x)
the aggregate Credit Exposures of all Lenders taken together to exceed the Total
Commitment at such time or (y) with respect to a Fronted Letter of Credit, the
Letter of Credit Outstandings in respect of all Fronted Letters of Credit issued
by the applicable Fronting Lender to exceed the maximum aggregate Stated Amount
of all Fronted Letters of Credit that such Fronting Lender has agreed to issue
in a separate agreement with the Company, (ii) the Stated Amount of a Letter of
Credit may not be increased at any time if the conditions precedent set forth in
Section 4.02 are not satisfied at such time, and (iii) the Stated Amount of a
Letter of Credit may not be increased at any time after the Commitment
Expiration Date.

          SECTION 2.09. Termination and Reduction of Commitments. (a) Unless
previously terminated, the Total Commitment (and the Commitment of each Lender)
shall terminate on the Commitment Expiration Date.

          (b) The Company may at any time terminate, or from time to time
reduce, the Total Commitment; provided that (i) each reduction of the Total
Commitment shall be in an amount that is an integral multiple of $1,000,000 and
not less than $5,000,000 and (ii) the Company shall not terminate or reduce the
Total Commitment if, after giving effect to such termination or reduction and
any concurrent prepayment of the Loans in accordance with Section 2.23, the
aggregate Credit Exposures of all Lenders taken together would exceed the Total
Commitment. Each such reduction shall be applied to the Commitments of the
Lenders on a pro rata basis based on the amount of such Lenders' respective
Commitments.

                                       29

<PAGE>

          (c) The Company shall notify the Administrative Agent of any election
to terminate or reduce the Total Commitment under paragraph (b) of this Section
2.09 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
Company pursuant to this Section shall be irrevocable; provided that a notice of
termination of Commitments may state that such notice is conditioned upon the
effectiveness of other credit facilities or other alternative financing, in
which case such notice may be revoked without penalty prior to the specified
time if such condition is not satisfied (each such notice a "Conditional
Termination Notice"). Any termination or reduction of the Total Commitment (or
the Commitments of any Lender) shall be permanent. Each reduction of the Total
Commitment shall be made ratably among the Lenders in accordance with their
respective Commitments.

          SECTION 2.10. Mandatory Prepayment; Cash Collateralization. (a) If (i)
as of the Commitment Expiration Date, any Letter of Credit may for any reason
remain outstanding, (ii) at any time, the aggregate amount of all Letter of
Credit Outstandings exceeds the Total Commitment as then in effect, (iii) any
Event of Default occurs and is continuing and the Administrative Agent or the
Required Lenders, as applicable, require the Company and the other Account
Parties to deposit in an account (which account may be a securities account with
the meaning of Section 8-501 of the Uniform Commercial Code as in effect in the
State of New York) with the Administrative Agent, in the name of the
Administrative Agent and for the benefit of the Lenders (any such account, a
"Collateral Account"), amounts of cash and Cash Equivalents, to be held as
security for each Account Party's reimbursement obligations in respect of
Letters of Credit then outstanding or (iv) an Event of Default set forth under
Section 7.05 occurs and is continuing, then the Company shall, or shall cause
one or more other Account Parties to, deposit in a Collateral Account on such
date an amount of cash or Cash Equivalents to be held as additional security for
the obligations of each of the Account Parties hereunder such that the amount of
cash and Cash Equivalents in such Collateral Account applicable to each Account
Party would equal the aggregate amount of all Letter of Credit Outstandings and
other obligations in respect of Letters of Credit attributable to such Account
Party hereunder, or in the case of clause (ii) above, the excess referred to in
such clause (ii). If at any time the Administrative Agent determines that any
funds held in a Collateral Account pursuant to this Section 2.10(a) are subject
to any right or claim of any Person other than the Agents (on behalf of the
Lenders) or that the total amount of such funds is less than the aggregate
amount of all Letter of Credit Outstandings and other obligations of the Account
Parties hereunder, or in the case of clause (ii) above, the excess referred to
in such clause (ii), the Company shall, or shall cause one or more Account
Parties to, forthwith upon demand by the Administrative Agent, pay to the
Administrative Agent, as additional funds to be deposited and held in a
Collateral Account as aforesaid, an amount equal to the excess of (a) the
aggregate amount of all Letter of Credit Outstandings and other obligations in
respect of Letters of Credit of the Account Parties hereunder over (b) the total
amount of cash and Cash Equivalents deposited in the Collateral Account as
aforesaid that the Administrative Agent reasonably determines to be free and
clear of any such right and claim, or in the case of clause (ii) above, the
excess referred to in such clause (ii). With respect to any payment to an
account required by clause (iii) of the first sentence of this Section 2.10(a),
such payment shall (to the extent not applied to the applicable reimbursement
obligations) be returned to the Company within three Business Days after the
applicable Event of Default shall have been cured or waived.

                                       30

<PAGE>

          (b) If on any date the aggregate Credit Exposures exceed the Total
Commitment as then in effect, the Company shall (i) first, prepay on such date
the principal amount of outstanding Loans in amount equal to the lesser of (x)
the amount of any such excess and (y) the principal amount of all outstanding
Loans at such time and (ii) second, cash collateralize any remaining amount of
such excess in the manner specified in clause (a) above.

          SECTION 2.11. Fees. (a) Each Account Party jointly and severally
agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee (the "Commitment Fee"), which shall accrue at the Applicable Rate
with respect to the Commitment Fee on the daily amount of the unutilized
Commitment of such Lender during the period from and including the Effective
Date to but excluding the Commitment Expiration Date. Accrued commitment fees
shall be payable in arrears on the last day of March, June, September and
December of each year and on the Commitment Expiration 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 365 days (or 366 days in a leap year) and
shall be payable for the actual number of days elapsed (including the first day
but excluding the last day).

          (b) The Company agrees to pay to each Agent, for its own account, fees
payable in the amounts and at the times separately agreed upon between the
Company and the applicable Agent.

          (c) Each Account Party severally agrees to pay to the Administrative
Agent for pro rata distribution to each Lender (based on their respective
Applicable Percentages), a fee in respect of each Letter of Credit issued for
the account of such Account Party (the "Letter of Credit Fee") computed at a
rate per annum equal to the Applicable Rate with respect to the Letter of Credit
Fee on the daily Stated Amount of such Letter of Credit. Accrued Letter of
Credit Fees shall be due and payable in arrears on the last day of March, June,
September and December of each year and upon the first day after the termination
of the Total Commitment upon which no Letters of Credit remain outstanding. All
Letter of Credit Fees shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

          (d) Each Account Party severally agrees to pay to each Fronting
Lender, for its own account, a fronting fee in respect of, and fees with respect
to the issuance, amendment, renewal or extension of, or processing of drawings
under, each Fronted Letter of Credit issued by such Fronting Lender for the
account of such Account Party, in each case in amounts and on dates as shall
have separately been agreed to by the Company and such Fronting Lender. Each
Account Party severally agrees to pay to the Issuing Agent fees with respect to
the issuance, amendment, renewal or extension of, and processing of drawings
under, each Several Letter of Credit issued for the account of such Account
Party, in each case in amounts and on dates as shall have separately been agreed
to by the Company and the Issuing Agent.

          (e) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent for distribution to the
Persons entitled thereto as set forth above. Fees paid shall not be refundable
under any circumstances. If any fee or other amount payable by any Account Party
hereunder is not paid when due, such overdue amount

                                       31

<PAGE>

shall bear interest, after as well as before judgment, at a rate per annum equal
to the Alternate Base Rate plus 2% per annum.

          SECTION 2.12. Taxes. (a) Any and all payments by or on account of any
obligation of any Account Party hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if
such Account Party 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, Issuing Agent or Lender (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) such
Account Party shall make such deductions and (iii) such Account Party shall pay
the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

          (b) In addition, each Account Party shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c) Each Account Party severally (and not jointly) agrees to indemnify
the Administrative Agent, the Issuing Agent and each Lender within 10 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes that such Account Party failed to deduct or withhold and that were paid by
the Administrative Agent, the Issuing Agent or such Lender on or with respect to
any payment by or on account of any obligation of such Account Party hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable out-of-pocket 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 (with reasonable detail) delivered to
any Account Party by a Lender or by the Administrative Agent or the Issuing
Agent on its own behalf or on behalf of a Lender, shall be conclusive absent
manifest error.

          (d) As soon as reasonably practicable after any payment of Indemnified
Taxes or Other Taxes by any Account Party to a Governmental Authority, such
Account Party 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) Each Lender shall, to the extent it may lawfully do so, deliver to
the Company (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Company (if any), or
will comply with such other requirements, if any, as is currently applicable, as
will permit payments under this Agreement to be made without withholding or at a
reduced rate.

          (f) If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to
which it has been indemnified by any Account Party or with respect to which such
Account Party has paid additional amounts

                                       32

<PAGE>

pursuant to this Section 2.12, it shall pay over such refund to such Account
Party (but only to the extent of indemnity payments made, or additional amounts
paid, by such Account Party under this Section 2.12 with respect to the Taxes or
Other Taxes giving rise to such refund), net of all reasonable out-of-pocket
expenses of the Administrative Agent or such Lender incurred in obtaining such
refund and without interest (other than any interest paid by the relevant
Governmental Authority with respect to such refund); provided that such Account
Party, upon the request of the Administrative Agent or such Lender, agrees to
repay the amount paid over to such Account Party (plus any penalties, interest
or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent or such Lender in the event the Administrative Agent or
such Lender is required to repay such refund to such Governmental Authority.
This Section shall not be construed to require the Administrative Agent or any
Lender to make available its tax returns (or any other information relating to
its taxes which it deems confidential) to such Account Party or any other
Person.

          (g) Any Lender that is not a Lender as of the Effective Date shall not
be entitled to any greater payment under this Section 2.12 than such Lender's
assignor could have been entitled to absent such assignment except to the extent
that the entitlement to a greater payment resulted from a Change in Law.

          SECTION 2.13. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) Each Account Party shall make each payment required to be made by
it hereunder (whether of principal, interest, fees or of amounts payable under
Section 2.06 or 2.12 or otherwise, except as expressly set forth in Section
2.05) prior to 12:00 noon (or, in the case of any prepayment or repayment in
full of all outstanding Letters of Credit and/or all outstanding Loans, 2:00
p.m.), New York City time, on the date when due, in immediately available funds,
without set-off or counterclaim in Dollars. 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 thereon. All such payments shall be made to the
Administrative Agent at its offices at 1111 Fannin, 8th floor, Houston, Texas
77002, except that payments pursuant to Sections 2.06, 2.12 and 10.03 shall be
made directly to the Persons entitled thereto. The Administrative Agent shall
distribute any such payments received by it for the 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.

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

          (c) 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 Unpaid Drawings, Loans or any fees payable pursuant to
Section 2.11 resulting in such Lender receiving

                                       33

<PAGE>

payment of a greater proportion of the aggregate amount of such obligations then
due and owed to such Lender, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in such obligations of
the respective Account Party or the Company, as the case may be, owed to such
Lenders to the extent necessary so that the benefit of all such payments shall
be shared by the Lenders ratably; provided that (i) if any such participations
are 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 Account Party 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 Commitment or Loans to
any assignee or participant, other than to any Account Party or any Subsidiary
or Affiliate thereof (as to which the provisions of this paragraph shall apply).
Each Account Party 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
Account Party rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Account
Party in the amount of such participation.

          (d) Unless the Administrative Agent shall have received notice from
the relevant Account Party prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders hereunder that such Account
Party will not make such payment, the Administrative Agent may assume that such
Account Party has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders the amount due. In
such event, if the relevant Account Party has not in fact made such payment,
then each of the Lenders severally agrees to repay to the Administrative Agent
forthwith on demand the amount so distributed to such 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
greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation.

          (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.13(d), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender's obligations under such Section until all such
unsatisfied obligations are fully paid.

          SECTION 2.14. Mitigation Obligations; Replacement of Lenders. (a) If
any Lender requests compensation under Section 2.06, or if each Account Party is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.06 or Section
2.12, then such Lender shall use reasonable efforts to designate a different
lending office for issuing or funding its Letters of Credit and funding or
booking of 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 2.06 or 2.12, 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. Each Account Party hereby
jointly and

                                       34

<PAGE>

severally agrees to pay all reasonable costs and expenses incurred by any Lender
in connection with any such designation or assignment.

          (b) If any Lender requests compensation under Section 2.06, or if each
Account Party is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.06 or
Section 2.12, then, in each case, the Company, at its sole expense and effort,
shall have the right, if no Default or Event of Default then exists, to replace
such Lender (the "Replaced Lender"), with one or more Person or Persons
(collectively, the "Replacement Lender") reasonably acceptable to the
Administrative Agent at which time the Replaced Lender shall 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 the Replacement Lender; provided that (i) at the time of any
replacement pursuant to this Section 2.14, the Replacement Lender and the
Replaced Lender shall enter into one or more Assignment and Assumptions pursuant
to Section 10.04(b) (and with all fees payable pursuant to said Section 10.04(b)
to be paid by the Replacement Lender) pursuant to which the Replacement Lender
shall acquire all of the Commitments and outstanding Loans of the Replaced
Lender and, in connection therewith, shall pay to the Replaced Lender in respect
thereof an amount equal to the sum of (A) an amount equal to (i) all Unpaid
Drawings that have been funded by (and not reimbursed to) such Replaced Lender,
together with all then unpaid interest with respect thereto at such time and
(ii) the principal amount of, and all accrued but unpaid interest on, all
outstanding Loans of the Replaced Lender and (B) an amount equal to all accrued,
but theretofore unpaid, fees owing to the Replaced Lender pursuant to Section
2.11; (ii) all obligations of each Account Party under this Agreement owing to
the Replaced Lender (other than those specifically described in clause (i) above
in respect of which the assignment purchase price has been, or is concurrently
being, paid), including all amounts owing to the Replaced Lender under Section
2.25 as a result of the assignment of its Loans under clause (i) above, shall be
paid in full to such Replaced Lender concurrently with such replacement; (iii)
no assignment pursuant to this Section 2.14 shall be effective until all of the
then outstanding Several Letters of Credit are returned by each respective
beneficiary to the Issuing Agent for cancellation in exchange for new or amended
Several Letters of Credit which give effect to such assignment (it being
understood that to the extent the respective beneficiaries do not consent to
such assignment, such assignment cannot occur); (iv) the Company shall have
received the prior written consent of the Administrative Agent and each Fronting
Lender, which consents shall not be unreasonably withheld or delayed; (v) such
assignment will result in a reduction in such compensation or payments; and (vi)
no Lender shall be required to become a Replaced Lender if, prior thereto, as a
result of a waiver by such Lender or otherwise, the circumstances entitling the
Company to require such assignment and delegation cease to apply. Upon the
execution of the respective Assignment and Assumption, the payment of amounts
referred to in clauses (i) and (ii) above and the return, and cancellation and
exchange of each then outstanding Several Letter of Credit as provided above
and, if so requested by the Replacement Lender, delivery to the Replacement
Lender of the appropriate promissory note or notes executed by the Company, the
Replacement Lender shall become a Lender hereunder and the Replaced Lender shall
cease to constitute a Lender hereunder, except with respect to indemnification
provisions applicable to the Replaced Lender under this Agreement, which shall
survive as to such Replaced Lender. For the avoidance of doubt, no Replaced
Lender shall be required to execute, sign or deliver any document or assignment
in order to be replaced in accordance with this Section 2.14.

                                       35

          SECTION 2.15. Designated Subsidiary Account Parties. The Company may
from time to time designate one or more Persons as an additional Designated
Subsidiary Account Party, subject to the following terms and conditions:

          (a) each such Person shall be a Wholly-Owned Subsidiary of the
Company;

          (b) each such Designated Subsidiary Account Party shall enter into an
appropriately completed DSAP Assumption Agreement on or prior to the date of
designation hereof;

          (c) on or prior to the date of designation, the Administrative Agent
shall have received from such Person a certificate, signed by an Authorized
Officer of such Person in the form of Exhibit H or such other form reasonably
acceptable to the Administrative Agent with appropriate insertions or deletions,
together with (x) copies of its certificate of incorporation, by-laws or other
organizational documents and (y) the resolutions of the board of directors (or
similar governing body) of such Person relating to this Agreement which shall be
reasonably satisfactory to the Administrative Agent; and

          (d) on or prior to the date of designation, the Administrative Agent
shall have received an opinion, addressed to the Administrative Agent and each
of the Lenders and dated the date of designation, which opinion shall be in form
and substance reasonably satisfactory to the Administrative Agent, from counsel
to the respective Designated Subsidiary Account Party reasonably satisfactory to
the Administrative Agent, covering certain of the matters set forth in the
opinions of counsel delivered to the Administrative Agent on the Effective Date
pursuant to Section 4.01(b)(iii), as may be reasonably requested by the
Administrative Agent, and such other matters incident to the transactions
contemplated thereby as the Administrative Agent may reasonably request.

          SECTION 2.16. Loans. Subject to and upon the terms and conditions
herein set forth, each Lender severally agrees, at any time and from time to
time on and after the Effective Date and prior to the Commitment Expiration
Date, to make a loan or loans (each, a "Loan" and, collectively, the "Loans") to
the Company, which Loans (i) may be made and maintained only in Dollars; (ii)
may be repaid and reborrowed in accordance with the provisions hereof; (iii)
except as hereinafter provided, may, at the option of the Company, be incurred
and maintained as, and/or converted into, ABR Loans or Eurodollar Loans,
provided that all Loans made as part of the same Borrowing shall, unless
otherwise specified herein, consist of Loans of the same Type; and (iv) shall
not be made (and shall not be required to be made) by any Lender if the making
of same would cause the aggregate Credit Exposures of all Lenders taken together
(after giving effect to the use of the proceeds thereof on the date of the
incurrence thereof to repay any amounts theretofore outstanding pursuant to this
Agreement) to exceed the Total Commitment as then in effect.

          SECTION 2.17. Loans and Borrowings.

          (a) Each Loan shall be made as part of a Borrowing consisting of Loans
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

                                       36

<PAGE>

obligations hereunder nor shall any other party be liable for the failure by
such Lender to perform its obligations hereunder.

          (b) Subject to Section 2.24, each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as the Company 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 Company to repay such Loan in accordance with the terms of this
Agreement.

          (c) At the commencement of each Interest Period for any Eurodollar
Borrowing, such Borrowing shall be in an aggregate principal amount of not less
than $5,000,000. At the time that each ABR Borrowing is made, such Borrowing
shall be in an aggregate amount that is an integral multiple of $1,000,000 and
not less than $5,000,000; provided that a Borrowing may be in an aggregate
amount that is equal to the entire unused balance of the Total Commitment.
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.

          (d) Notwithstanding any other provision of this Agreement, the Company
shall not be entitled to request, or to elect to convert or continue, any
Borrowing if the Interest Period requested with respect thereto would end after
the Commitment Expiration Date.

          SECTION 2.18. Requests for Borrowings. To request a Borrowing, the
Company shall notify the Administrative Agent of such request by telephone (a)
in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York City
time, three Business Days before the date of the proposed Borrowing and (b) in
the case of an ABR Borrowing, not later than 11:00 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 delivery or facsimile or
electronic mail to the Administrative Agent of a Borrowing Request in the form
of Exhibit B or such other form reasonably acceptable to the Administrative
Agent appropriately completed and signed by the Company. Each such telephonic
and written Borrowing Request shall specify the following information in
compliance with Section 2.17:

          (i) the aggregate principal 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 initial Interest
     Period to be applicable thereto, which shall be a period contemplated by
     the definition of the term "Interest Period"; and

          (v) the location and number of the Company's account to which funds
     are to be disbursed.

                                       37

<PAGE>

          If no election as to the Type of Borrowing of Loans is specified, then
such Borrowing of Loans shall be an ABR Borrowing. If no Interest Period is
specified with respect to any requested Eurodollar Borrowing, then the Company
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 2.19. Funding of Borrowings.

          (a) Each Lender shall make each Loan on the proposed date thereof by
wire transfer of immediately available funds by 12:00 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 Company by wire transfer of immediately available funds
not later than 1:00 p.m., New York City time, to the account of the Company
designated by it in the applicable Borrowing Request.

          (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing (or prior to 1:00 p.m., New
York City time, on the date of such Borrowing in the case of ABR Borrowings)
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 Company 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 Company 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 Company to but excluding the date of payment to the Administrative Agent,
at (i) in the case of such Lender, the greater of the Federal Funds Effective
Rate and a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the
Company, 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 and the Company's obligations to repay
the Administrative Agent in accordance with the previous sentence shall cease to
the extent such Lender has paid such amounts.

          SECTION 2.20. Interest Elections.

          (a) Each Borrowing initially shall be of the Type specified in the
applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request.
Thereafter, the Company may elect to convert such Borrowing to a different Type
or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may
elect Interest Periods therefor, all as provided in this Section 2.20. Subject
to the other provisions of this Section 2.20, the Company 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 comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing.

                                       38

<PAGE>

          (b) To make an election pursuant to this Section (an "Interest
Election Request"), the Company shall notify the Administrative Agent of such
election by telephone by the time that a Borrowing Request would be required
under Section 2.18 if the Company 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 delivery or facsimile or electronic mail to the
Administrative Agent of an Interest Election Request in the form of Exhibit E,
or such other form reasonably acceptable to the Administrative Agent, and signed
by the Company.

          (c) Each Interest Election Request shall specify the following
information in compliance with Section 2.17:

               (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) below 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 to be applicable thereto 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 Company shall be deemed to
have selected an Interest Period of one month's duration.

          (d) 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) If the Company fails to deliver a timely Interest Election Request
with respect to a Eurodollar Borrowing prior to the end of the Interest Period
applicable thereto, 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 anything to the contrary contained in this Agreement,
if an Event of Default is in existence, then, so long as an Event of Default is
in existence (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 applicable
thereto.

          SECTION 2.21. Repayment of Loans; Evidence of Debt.

                                       39

<PAGE>

          (a) The Company hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of all Loans on the Commitment Expiration Date.

          (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Company 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) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Company to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender's share thereof.

          (d) The entries made in the accounts 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 accounts or any error
therein shall not in any manner affect the obligation of the Company to repay
the Loans in accordance with the terms of this Agreement.

          (e) Any Lender may request by written notice to the Company and the
Administrative Agent that Loans made by it be evidenced by a promissory note
(which may be executed by facsimile). In such event, the Company 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 the form of Exhibit D or such other form reasonably acceptable
to 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 2.22. Voluntary Prepayment of Loans.

          (a) The Company shall have the right at any time and from time to time
to prepay any Borrowing in whole or in part, without premium or penalty, except
as provided in Section 2.25, subject to prior notice in accordance with
paragraph (b) of this Section.

          (b) The Company shall notify the Administrative Agent by telephone
(confirmed by facsimile or electronic mail) of any prepayment hereunder (i) in
the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, 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 12:00 noon, New York City
time, on the date of prepayment. Each such notice shall be irrevocable (unless
given in connection with a Conditional Termination Notice, as set forth in
Section 2.09, in which case, subject to Section 2.25, such notice of prepayment
may be revoked if such Conditional Termination Notice is revoked in accordance

                                       40
<PAGE>

with Section 2.09) and shall specify the prepayment date, the Borrowing or
Borrowings which are to be prepaid and the principal amount of each Borrowing or
portion thereof to be prepaid. 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 2.17. 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 2.23.

          SECTION 2.23. Interest.

          (a) The ABR Loans shall bear interest at the Alternate Base Rate plus
the Applicable Rate with respect to ABR Loans. The Eurodollar Loans shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such
Loan plus the Applicable Rate with respect to Eurodollar Loans.

          (b) For any day on which the outstanding principal amount of all Loans
shall be equal to or greater than 50% of the Total Commitment, the "Eurodollar
Spread" and the "ABR Spread" as set forth in the definition of "Applicable Rate"
shall be increased (a "Utilization Increase") in an amount equal to the
Applicable Rate with respect to the Utilization Increase on the aggregate amount
of each Lender's outstanding Loans to the Company on such day.

          (c) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Company hereunder is not paid
when due, whether at stated maturity, upon acceleration 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 in the preceding paragraphs
of this Section 2.23 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 2.23.

          (d) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and on the Commitment Expiration Date;
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
Expiration 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 Loan prior to the end of the current
Interest Period therefor, accrued interest on such Loan shall be payable on the
effective date of such conversion.

          (e) 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.

                                       41

<PAGE>

          SECTION 2.24. Alternate Rate of Interest. If prior to the commencement
of any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent reasonably 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 (based
on the reasonable determination of such 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 Company and the
Lenders by telephone (followed by written or facsimile notice) or facsimile or
in writing as promptly as practicable thereafter and, until the Administrative
Agent notifies the Company 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 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 provided that if the circumstances giving rise to such notice affect
only one Type of Borrowings, then the other Type of Borrowings shall be
permitted.

          SECTION 2.25. 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 applicable thereto (including as a result of a mandatory
prepayment under Section 2.10 or the occurrence of an Event of Default), (b) the
conversion of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Eurodollar 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 the Interest Period applicable thereto as a result of a request by
the Company pursuant to Section 2.14, then, in any such event, the Company shall
compensate each Lender for the loss, cost and expense attributable to such
event. In the case of a Eurodollar Loan, such loss, cost or expense to any
Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest which would have accrued on the
principal amount of such Loan had such event not occurred, at the Adjusted LIBO
Rate that would have been applicable to such Loan, for the period from the date
of such event to the last day of the then current Interest Period therefor (or,
in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Loan), over (ii) the amount of
interest which would accrue on such principal amount for such period at the
interest rate which such Lender would bid were it to bid, at the commencement of
such period, for dollar deposits of a comparable amount and period from other
banks in the Eurodollar market. A certificate of any Lender setting forth in
reasonable detail any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the Company and shall be
conclusive absent manifest error. The Company shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

misleading at such time in light of the circumstances under which such
information was provided; provided that with respect to projections, the Company
or the applicable Designated Subsidiary Account Party represents only that the
projections contained in such materials are based on good faith estimates and
assumptions believed by the Company to be reasonable and attainable at the time
made, it being recognized by the Administrative Agent and the Lenders that such
projections as to future events are not to be viewed as facts and are subject to
significant uncertainties and contingencies many of which are beyond the
Company's control and that actual results during the period or periods covered
by any such projections may differ from the projected results.

          SECTION 3.09. Financial Condition. (a) The Company has heretofore
furnished to the Lenders its consolidated balance sheet and consolidated
statements of operations and comprehensive income (loss), shareholders' equity
and cash flows as of and for the fiscal year ended December 31, 2006 reported on
by PricewaterhouseCoopers, independent public accountants. Such financial
statements present fairly, in all material respects, the financial position and
results of operations and cash flows of the Borrower and its consolidated
Subsidiaries as of such dates and for such periods in accordance with GAAP.

          (b) Since December 31, 2006, nothing has occurred, either individually
or in the aggregate, which has resulted in, or would reasonably be expected to
result in, any material adverse condition or any material adverse change in or
affecting (i) the business, operations, assets, liabilities or financial
condition of the Company and its Subsidiaries, taken as a whole, or (ii) the
rights and remedies of the Lenders or the ability of the Company and each other
Account Party, taken as a whole, to perform their respective obligations to the
Lenders under this Agreement.

          SECTION 3.10. Tax Returns and Payments. Except where the failure to do
so would not reasonably be expected, individually or in aggregate, to have a
Material Adverse Effect, the Company and its Subsidiaries (i) have timely filed
or caused to be timely filed with the appropriate taxing authority (taking into
account any applicable extension within which to file) all material income and
other material tax returns (including any statements, forms and reports),
domestic and foreign, required to be filed by the Company and its Subsidiaries,
and (ii) have timely paid, collected or remitted or caused to have timely paid,
collected or remitted all material taxes payable by them which have become due
and assessments which have become due, except for those contested in good faith
and adequately disclosed and for which adequate reserves have been established
in accordance with GAAP. To the best knowledge of the Company and its
Subsidiaries, there is no action, suit, proceeding, investigation, audit or
claim now pending or proposed or threatened by any authority regarding any
income taxes or any other taxes relating to the Company or any of its
Subsidiaries, which, either individually or in the aggregate, has had, or would
reasonably be expected to have, a Material Adverse Effect. As of the Effective
Date, neither the Company nor any of its Subsidiaries has entered into an
agreement or waiver or been requested to enter into an agreement or waiver
extending any statute of limitations relating to the payment or collection of
taxes of the Company or any of its Subsidiaries. To the best knowledge of the
Company and its Subsidiaries, no tax Liens have been filed and no claims are
pending or proposed or threatened with respect to any taxes, fees or other
charges for any taxable period, except for Liens permitted under Section 6.03
and claims which, either individually or in the aggregate, have not had, and
would not reasonably be expected to have, a Material Adverse Effect.

          SECTION 3.11. Compliance with ERISA. (a) Except as, either
individually or in the aggregate, has not had, and would not reasonably be

     a liability to the Company or any of its Subsidiaries in excess of
     $15,000,000;

          (iv) the receipt by the Company, any of its Subsidiaries or any of its

     4241 or 4245 of ERISA or that it intends to terminate or

                                       55

<PAGE>

     has terminated under Section 4041A of ERISA whereby a deficiency or

     that the Company or any Subsidiary of the Company may incur any liability
     in excess of $15,000,000 pursuant to any Foreign Pension Plan (other than

cause each of its Subsidiaries to, maintain all of their properties and assets

would not reasonably be expected to have, a Material Adverse Effect.

          SECTION 5.10. Further Assurances. Each Account Party shall promptly
and duly execute and deliver to the Administrative Agent such documents and
assurances and take such further action as the Administrative Agent may from
time to time reasonably request in order to carry out more effectively the

                                  ARTICLE VIII

                                   The Agents

          SECTION 8.01. Appointment. Each of the Lenders hereby irrevocably
appoints each Agent as its agent and authorizes such Agent to take such actions
on its behalf and to exercise such powers as are delegated to such Agent by the
terms hereof, together with such actions and powers as are reasonably incidental
thereto.

          SECTION 8.02. Agents in their Individual Capacities. Each bank serving
as an 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 an
Agent, and such bank and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of business with the Company or any of its
Subsidiaries or other Affiliate thereof as if it were not an Agent hereunder.

          SECTION 8.03. Exculpatory Provisions. Each Agent shall not have any
duties or obligations except those expressly set forth herein. Without limiting
the generality of the foregoing, (a) no Agent shall be subject to any fiduciary
or other implied duties, regardless of whether a Default has occurred and is
continuing, (b) no Agent shall have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby that such Agent is required to exercise in writing
as directed by the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section
10.02), and (c) except as expressly set forth herein, no Agent shall have any
duty to disclose, and shall not be liable for the failure to disclose, any
information relating to the Company or any of its Subsidiaries that is
communicated to or obtained by the bank serving as such Agent or any of its
Affiliates in any capacity. No Agent shall be liable for any action taken or not
taken by it with the consent or at the request of the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 10.02) or in the absence of its own gross
negligence or willful misconduct. No Agent shall be deemed to have knowledge of
any Default unless and until written notice thereof is given to such Agent by
the Company or the applicable Account Party or a Lender, and no Agent shall 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, (ii)
the contents of any certificate, report or other document delivered hereunder or
in connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein, (iv) the
validity, enforceability, effectiveness or genuineness of this Agreement or any
other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to such Agent.

          SECTION 8.04. Reliance. Each 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. Each
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. Each Agent may consult with legal counsel (who
may be counsel for the

                                       67

<PAGE>

Company), 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.

          SECTION 8.05. Delegation of Duties. Each 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 such Agent. Each Agent and any such sub-agent may
perform any and all of 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
applicable 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 Agent.

          SECTION 8.06. Resignation. Subject to the appointment and acceptance
of an applicable successor Agent as provided in this paragraph, each Agent may
resign at any time by notifying the Lenders and the Company. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor
administrative agent or syndication agent with the consent of the Company (not
to be unreasonably withheld or delayed), provided that no such consent shall be
required at any time when a Default or Event of Default exists. If no successor
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within 30 days after the retiring Agent gives notice of its
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent which shall be a bank with an office in New York, New York, or
an Affiliate of any such bank. Upon the acceptance of its appointment as an
Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Account Parties to a successor Agent shall be
the same as those payable to its predecessor unless otherwise agreed between the
Company and such successor. After an Agent's resignation hereunder, the
provisions of this Article and Section 10.03 shall continue in effect for the
benefit of such retiring Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as an Agent.

          SECTION 8.07. Non-Reliance. Each Lender acknowledges that it has,
independently and without reliance upon any 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 any 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 related agreement or
any document furnished hereunder or thereunder.

          SECTION 8.08. Syndication Agent, Documentation Agents and Joint Lead
Arrangers and Joint Bookrunners. Notwithstanding any other provision of this
Agreement, each of the Syndication Agent, Documentation Agents and the Joint
Lead Arrangers and Joint Bookrunners is named as such for recognition purposes
only, and in its capacity as such shall have no powers, duties, responsibilities
or liabilities with respect to this Agreement or the transactions contemplated
hereby, except as expressly contemplated hereby. Without limitation

                                       68

<PAGE>

of the foregoing, the Syndication Agent, Documentation Agents and the Joint Lead
Arrangers and Joint Bookrunners shall not, solely by reason of this Agreement,
have any fiduciary relationship with any Lender or any other Person.

                                   ARTICLE IX

                                Company Guaranty

          SECTION 9.01. The Company Guaranty. In order to induce the Lenders to
enter into this Agreement and to extend credit hereunder and in recognition of
the direct benefits to be received by the Company from the issuance of the
Letters of Credit, the Company hereby agrees with the Lenders as follows: the
Company hereby unconditionally and irrevocably guarantees, as primary obligor
and not merely as surety, the full and prompt payment when due, whether upon
maturity, acceleration or otherwise, of any and all of the Guaranteed
Obligations of each Designated Subsidiary Account Party to the Guaranteed
Creditors. If any or all of the Guaranteed Obligations of any Designated
Subsidiary Account Party to the Guaranteed Creditors becomes due and payable
hereunder, the Company unconditionally promises to pay such Guaranteed
Obligations to the Guaranteed Creditors, or order, on demand, together with any
and all expenses which may be incurred by the Guaranteed Creditors in collecting
any of the Guaranteed Obligations. This Company Guaranty is a guaranty of
payment and not of collection. If a claim is ever made upon any Guaranteed
Creditor for repayment or recovery of any amount or amounts received in payment
or on account of any of the Guaranteed Obligations and any of the aforesaid
payees repays all or part of said amount by reason of (i) any judgment, decree
or order of any court or administrative body having jurisdiction over such payee
or any of its property or (ii) any settlement or compromise of any such claim
effected by such payee with any such claimant, then and in such event the
Company agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon the Company, notwithstanding any revocation of this
Company Guaranty or any other instrument evidencing any liability of each
Designated Subsidiary Account Party, and the Company shall be and remain liable
to the aforesaid payees hereunder for the amount so repaid or recovered to the
same extent as if such amount had never originally been received by any such
payee.

          SECTION 9.02. Bankruptcy. Additionally, the Company unconditionally
and irrevocably guarantees the payment of any and all of the Guaranteed
Obligations of each Designated Subsidiary Account Party hereunder to the
Guaranteed Creditors whether or not due or payable by each Designated Subsidiary
Account Party upon the occurrence of any of the events specified in Section 7.05
with respect to such Designated Subsidiary Account Party, and unconditionally
promises to pay such indebtedness to the Guaranteed Creditors, or order, on
demand, in lawful money of the United States.

          SECTION 9.03. Nature of Liability. The liability of the Company
hereunder is exclusive and independent of any other guaranty of the Guaranteed
Obligations of each Designated Subsidiary Account Party whether executed by the
Company, any other guarantor or by any other party, and the liability of the
Company hereunder is not affected or impaired by (a) any direction as to
application of payment by each Designated Subsidiary Account Party or by any
other party (other than a direction by the Guaranteed Creditor receiving such
payment), or (b) any other continuing or other guaranty, undertaking or maximum
liability

                                       69

<PAGE>

of a guarantor or of any other party as to the Guaranteed Obligations of each
Designated Subsidiary Account Party, or (c) any payment on or in reduction of
any such other guaranty or undertaking, or (d) any dissolution, termination or
increase, decrease or change in personnel by each Designated Subsidiary Account
Party, or (e) any payment made to the Guaranteed Creditors on the Guaranteed
Obligations which any such Guaranteed Creditor repays to each Designated
Subsidiary Account Party pursuant to court order in any bankruptcy,
reorganization, arrangement, moratorium or other debtor relief proceeding, and
the Company waives any right to the deferral or modification of its obligations
hereunder by reason of any such proceeding or (f) any action or inaction of the
type described in Section 9.05.

          SECTION 9.04. Independent Obligation. The obligations of the Company
under this Article IX are independent of the obligations of any other guarantor,
any other party or each Designated Subsidiary Account Party, and a separate
action or actions may be brought and prosecuted against the Company whether or
not action is brought against any other guarantor, any other party or each
Designated Subsidiary Account Party and whether or not any other guarantor, any
other party or each Designated Subsidiary Account Party be joined in any such
action or actions. The Company waives, to the full extent permitted by law, the
benefit of any statute of limitations affecting its liability under this Article
IX or the enforcement thereof. Any payment by a Designated Subsidiary Account
Party or other circumstance which operates to toll any statute of limitations as
to a Designated Subsidiary Account Party shall operate to toll the statute of
limitations as to the Company.

          SECTION 9.05. Authorization. The obligations of the Company under this
Article IX shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by any action taken by any Guaranteed Creditor to:

          (a) change the manner, place or terms of payment of, and/or change or
extend the time of payment of, renew, increase, accelerate or alter, any of the
Guaranteed Obligations (including any increase or decrease in the rate of
interest thereon), any security therefor, or any liability incurred directly or
indirectly in respect thereof, and the guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;

          (b) take and hold security for the payment of the Guaranteed
Obligations and sell, exchange, release, impair, surrender, realize upon or
otherwise deal with in any manner and in any order any property by whomsoever at
any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
Obligations or any liabilities (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and/or any offset
thereagainst, except to the extent the Guaranteed Obligations have been paid;

          (c) exercise or refrain from exercising any rights against any
Designated Subsidiary Account Party or others or otherwise act or refrain from
acting;

          (d) release or substitute any one or more endorsers, guarantors, any
Designated Subsidiary Account Party or other obligor;

                                       70

<PAGE>

          (e) settle or compromise any of the Guaranteed Obligations, any
security therefor or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and may subordinate the
payment of all or any part thereof to the payment of any liability (whether due
or not) of any Designated Subsidiary Account Party to its creditors other than
the Guaranteed Creditors;

          (f) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of any Designated Subsidiary Account Party to the
Guaranteed Creditors regardless of what liability or liabilities of any
Designated Subsidiary Account Party remain unpaid;

          (g) consent to or waive any breach of, or any act, omission or default
under, this Agreement or any of the instruments or agreements referred to herein
or therein, or otherwise amend, modify or supplement this Agreement or any of
such other instruments or agreements; and/or

          (h) take any other action which would, under otherwise applicable
principles of common law, give rise to a legal or equitable discharge of the
Company from its liabilities under this Company Guaranty.

          SECTION 9.06. Reliance. It is not necessary for the Guaranteed
Creditors to inquire into the capacity or powers of any Designated Subsidiary
Account Party or the officers, directors, partners or agents acting or
purporting to act on their behalf, and any Guaranteed Obligations made or
created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

          SECTION 9.07. Subordination. Any indebtedness of any Designated
Subsidiary Account Party now or hereafter owing to the Company is hereby
subordinated to the Guaranteed Obligations of each Designated Subsidiary Account
Party owing to the Guaranteed Creditors; and if the Administrative Agent so
requests at a time when an Event of Default exists, no Designated Subsidiary
Account Party shall make, or be permitted to make, any payment to the Company in
respect of such indebtedness owed to the Company, but without affecting or
impairing in any manner the liability of the Company under the other provisions
of this Company Guaranty. Prior to the transfer by the Company of any note or
negotiable instrument evidencing any of the indebtedness of any Designated
Subsidiary Account Party to the Company, the Company shall mark such note or
negotiable instrument with a legend that the same is subject to this
subordination. Without limiting the generality of the foregoing, the Company
hereby agrees with the Guaranteed Creditors that it will not exercise any right
of subrogation which it may at any time otherwise have as a result of this
Company Guaranty (whether contractual, under Section 509 of the Bankruptcy Code
or otherwise) until all Guaranteed Obligations have been irrevocably paid in
full in cash.

          SECTION 9.08. Waiver. (a) The Company waives any right (except as
shall be required by applicable statute and cannot be waived) to require any
Guaranteed Creditor to (i) proceed against any Designated Subsidiary Account
Party, any other guarantor or any other party, (ii) proceed against or exhaust
any security held from any Designated Subsidiary Account Party, any other
guarantor or any other party or (iii) pursue any other remedy in any Guaranteed
Creditor's power whatsoever. The Company waives any defense based on or arising
out of any

                                       71

<PAGE>

defense of any Designated Subsidiary Account Party, any other guarantor or any
other party, other than payment in full of the Guaranteed Obligations, based on
or arising out of the disability of any Designated Subsidiary Account Party, any
other guarantor or any other party, or the unenforceability of the Guaranteed
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of any Designated Subsidiary Account Party other than payment
in full of the Guaranteed Obligations. The Guaranteed Creditors may exercise any
right or remedy the Guaranteed Creditors may have against any Designated
Subsidiary Account Party or any other party, or any security, without affecting
or impairing in any way the liability of the Company hereunder except to the
extent the Guaranteed Obligations have been paid. The Company waives any defense
arising out of any such election by the Guaranteed Creditors, even though such
election operates to impair or extinguish any right of reimbursement or
subrogation or other right or remedy of the Company against any Designated
Subsidiary Account Party or any other party or any security.

          (b) The Company waives all presentments, demands for performance,
protests and notices, including notices of non-performance, notices of protest,
notices of dishonor, notices of acceptance of this Company Guaranty, and notices
of the existence, creation or incurring of new or additional Guaranteed
Obligations. The Company assumes all responsibility for being and keeping itself
informed of each Designated Subsidiary Account Party's financial condition and
assets, and of all other circumstances bearing upon the risk of non-payment of
the Guaranteed Obligations and the nature, scope and extent of the risks which
the Company assumes and incurs hereunder, and agrees that the Guaranteed
Creditors shall have no duty to advise the Company of information known to them
regarding such circumstances or risks.

          (c) The Company warrants and agrees that each of the waivers set forth
above in this Section 9.08 is made with full knowledge of its significance and
consequences, and such waivers shall be effective to the maximum extent
permitted by law.

          (iii) if to the Administrative Agent, to JPMorgan Chase Bank, National
     Association, Loan and Agency Services Group, 1111 Fannin Street, Houston,
     Texas 77002, Attention of Marion Murray (Facsimile No. (713) 750-2228;
     e-mail: marion.murray@jpmchase.com), with a copy to JPMorgan Chase Bank,
     National Association, 270 Park Avenue, 22nd Floor, New York 10017,

     erin.orourke@jpmorgan.com); and

          (iv) if to any other Lender, to it at its address (or facsimile
     number) set forth in its Administrative Questionnaire.

          (b) Notices and other communications to the Lenders hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent; provided that the foregoing shall not
apply to notices pursuant to (x) Article II unless otherwise agreed by the
Administrative Agent and the applicable Lender or (y) Section 5.01(e)(x). The
Administrative Agent or the Company may, in its discretion, agree to accept
notices and other communications to it hereunder by electronic communications
pursuant to procedures approved by it; provided that approval of such procedures
may be limited to particular notices or communications.

          (c) Any party hereto may change its address or facsimile number for
notices and other communications hereunder by notice to the other parties
hereto. 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 failure or delay by the
Administrative Agent 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 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 Account Party
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section 10.02, 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, neither the issuance of any
Letter of Credit nor the making of any Loan shall be construed as a waiver of
any Default, regardless of whether the Administrative Agent or any Lender may
have had notice or knowledge of such Default at the time. In the case of any
waiver, each Account Party, the Administrative Agent and the Lenders shall be
restored to their former positions and rights hereunder and any Default or Event
of Default so waived shall be deemed to be cured and not continuing. No such
waiver shall extend to any subsequent or other Default or Event of Default or
impair any right consequent thereon.

          (b) 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 each Account Party and the Required Lenders or by each Account
Party and the Administrative Agent with the consent of the Required Lenders;
provided that no such agreement shall (i) increase the

                                       73

<PAGE>

Commitment or the Loan Exposure of any Lender without the written consent of
such Lender, (ii) reduce the amount of any amount due pursuant to any Letter of
Credit or Unpaid Drawing or any Loan or reduce any interest or fees payable
hereunder, without the written consent of each Lender affected thereby, (iii)
postpone the scheduled date for reimbursement of any Unpaid Drawing or payment
of any Loan, 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 the Commitments or any Letter of Credit, without the written
consent of each Lender affected thereby, (iv) change Section 2.13(b) or (c) in a
manner that would alter the pro rata sharing of payments required thereby or
change any of the provisions of this Section 10.02 or 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, (v) release the Company from the Company Guaranty (or
change the Company Guaranty in a manner that is materially adverse to the
Lenders), without the written consent of each Lender or (vi) change any
provision of Article II specifically relating to Letters of Credit without the
written consent of each LC Issuer affected thereby; and provided, further, that
no such agreement shall amend, modify or otherwise affect the rights or duties
of any Agent or any LC Issuer hereunder without the prior written consent of
such Agent or such LC Issuer, as the case may be. Notwithstanding the foregoing
or any other provision of this Agreement, any provision of this Agreement may be
amended by an agreement in writing entered into by the Company, the
Super-Majority Lenders and the Administrative Agent (and, if its rights or
obligations are affected thereby, each LC Issuer and the Issuing Agent) if (x)
by the terms of such agreement the Commitment of each Lender not consenting to
the amendment provided for therein shall terminate, and any Several Letters of
Credit then outstanding shall either be terminated, amended or returned and
reissued, in each case to give effect to such termination (it being understood
that the Company may cause the Commitment of any such non-consenting Lender to
be assigned to one or more new Lenders in accordance with Section 10.04;
provided that no action shall be required to be taken by such non-consenting
Lender (including the execution of any Assignment and Assumption Agreement)) and
(y) at the time such amendment becomes effective, each Lender not consenting
thereto receives payment in full of all amounts owing to it or accrued for its
account under this Agreement.

          SECTION 10.03. Expenses; Indemnity; Damage Waiver. (a) Each Account
Party jointly and severally agrees to pay (i) all out-of-pocket expenses
incurred by the Agents, the Joint Lead Arrangers and Joint Bookrunners and their
Affiliates, including the reasonable fees, charges and disbursements of counsel,
in connection with the syndication of the credit facility provided for herein,
the preparation and administration of this Agreement or any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions contemplated hereby or thereby shall be consummated) or protection
of its rights hereunder or thereunder, and (ii) all out-of-pocket expenses
incurred by any Agent, any Joint Lead Arranger and Joint Bookrunner or any
Lender, including the reasonable fees, charges and disbursements of one primary
counsel and all applicable foreign counsel thereto, in connection with the
enforcement of its rights in connection with this Agreement, including its
rights under this Section, or in connection with the Loans made and Letters of
Credit issued hereunder, including all such out-of-pocket expenses incurred
during any workout, restructuring or negotiations in respect of such Loans and
Letters of Credit.

                                       74

<PAGE>

          (b) Each Account Party jointly and severally agrees to indemnify the
Agents, the Joint Lead Arrangers and Joint Bookrunners and each Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and 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 any other transactions contemplated hereby,
(ii) any Letter of Credit, any Loan or the use of the proceeds therefrom, (iii)
any actual or alleged presence or release of Hazardous Materials on or from any
property owned or operated by the Company or any of its Subsidiaries, or any
Environmental Liability related in any way to the Company or any of its
Subsidiaries, 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
or whether such claim, litigation, investigation or proceeding is brought by the
Company or any of its Subsidiaries or a third party; provided that such
indemnity shall not, as to any Indemnitee or any Related Party of such
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 non-appealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee or any Related Party
of such Indemnitee.

          (c) To the extent that any Account Party fails to pay any amount
required to be paid by it to an Agent, under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to such Agent 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 such Agent, in its capacity as such.

          (d) To the extent permitted by applicable law, no Account Party shall
assert, and each Account Party 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, any Letter of Credit, any Loan or the use of the proceeds
thereof.

          (e) All amounts due under this Section shall be payable promptly after
written demand therefor.

          SECTION 10.04. Successors and Assigns. (a) 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 except that (i) no
Account Party 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 such Account Party without such consent shall be null
and void) and (ii) no Lender may assign or otherwise transfer its rights or
obligations hereunder except in accordance with this Section. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto,

                                       75

<PAGE>

their respective successors and assigns permitted hereby, 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 Agents and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

          (b) (i) Subject to the conditions set forth in paragraph (b)(ii)
below, any Lender may assign to one or more Persons 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 such Lender) with the prior
written consent (such consent not to be unreasonably withheld) of:

               (A) the Company, provided that no consent of the Company shall be
          required for an assignment to a Lender, an Affiliate of a Lender, an
          Approved Fund or, if an Event of Default has occurred and is
          continuing, any other assignee; and

               (B) the Administrative Agent and each LC Issuer.

               (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, the amount of the Commitment 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 Company and the Administrative Agent
          otherwise consent, provided that no such consent of the Company 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;

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

               (E) the assignee shall be an NAIC Approved Bank that is not a
          parent, subsidiary or Affiliate of any Account Party or any
          beneficiary under any Letter of Credit; and

               (F) if any Several Letters of Credit are then outstanding, no
          such assignment shall be effective until all such outstanding Several
          Letters of Credit are either amended or returned and reissued, in each
          case to give effect to such assignment.

                                       76

<PAGE>

          For the purposes of this Section 10.04(b), the term "Approved Fund"
has the following meaning:

          "Approved Fund" means any Person (other than a natural person) that is
engaged in making, purchasing, holding or investing in bank loans and similar
extensions of credit in the ordinary course of its business and that is
administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an
entity or an Affiliate of an entity that administers or manages a Lender.

          (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 (provided that any liability of any Account Party to
     such assignee under Section 2.06, 2.12 or 2.25 shall be limited to the
     amount, if any, that would have been payable thereunder by such Account
     Party in the absence of such assignment, except to the extent any such
     amounts are attributable to a Change in Law), 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 2.06, 2.12, 2.25 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.

          (iv) The Administrative Agent, acting for this purpose as an agent of
     the Account Parties, shall maintain at one of its offices 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 owing to, each Lender pursuant to the
     terms hereof from time to time (the "Register"). The entries in the
     Register shall be conclusive absent manifest error, and the Account
     Parties, the Administrative Agent 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
     Account Parties, and any Lender, at any reasonable time and from time to
     time upon reasonable prior notice.

          (v) 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

                                       77
<PAGE>

     purposes of this Agreement unless it has been recorded in the Register as
     provided in this paragraph.

          (c) (i) Any Lender may, without the consent of any Account Party or
the Administrative Agent, 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 (including all or a portion of its Commitment
and Unpaid Drawings and the Loans owing to it); provided that (A) such Lender's
obligations under this Agreement shall remain unchanged, (B) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (C) the Account Parties, the Administrative Agent 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. 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 to approve any amendment, modification or waiver of any provision
of this Agreement; 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 affects such Participant. Subject to paragraph (c)(ii) of this
Section, each Account Party agrees that each Participant shall be entitled to
the benefits of Sections 2.06, 2.12 and 2.25 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 2.13(c) as though it were a
Lender.

          (ii) A Participant shall not be entitled to receive any greater
     payment under Section 2.06 or 2.12 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 Company's prior written consent and the entitlement to
     greater payment results solely from a Change in Law. A Participant that
     would be a Foreign Lender if it were a Lender shall not be entitled to the
     benefits of Section 2.12 unless the Company is notified of the
     participation sold to such Participant and such Participant agrees, for the
     benefit of the Account Parties, to comply with Section 2.12(e) as though it
     were a Lender.

          (d) 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 pledge or assignment to secure obligations 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 any Account Party 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 issuance of any
Letters of Credit and the making of any Loan regardless of any investigation
made by any such other party or on its behalf and notwithstanding that the
Administrative Agent or any Lender may have had notice or knowledge of any
Default or

                                       78

<PAGE>

incorrect representation or warranty at the time any credit is extended
hereunder, and shall continue in full force and effect as long as any Letter of
Credit or the principal of or any accrued interest on any Loan is outstanding,
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Total Commitment (and the Commitment of each Lender)
has not expired or terminated. The provisions of Sections 2.06, 2.12, 2.25 and
10.03 and Article VIII 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 Total Commitment
(and the Commitment of each Lender) or the termination of this Agreement or any
provision hereof.

          SECTION 10.06. Counterparts; Integration; Effectiveness. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall 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 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. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by facsimile 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 of its Affiliates 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) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of any
Account Party against any of and all the obligations of such Account Party now
or hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 10.09. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

          (b) Each party hereto hereby irrevocably and unconditionally submits,
for itself and its property, to the exclusive jurisdiction of the Supreme Court
of the State of New

                                       79

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 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 or any Lender may otherwise have to bring
any action or proceeding relating to this Agreement against any Account Party or
its properties in the courts of any jurisdiction.

          (c) Each party hereto 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) Each party to this Agreement irrevocably consents to service of
process in connection with disputes arising out of this Agreement 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.

          (e) Each Account Party hereby irrevocably designates, appoints and
empowers the Service of Process Agent, with offices on the date hereof at 111
Eighth Avenue, New York, New York 10011, as its designee, appointee and agent to
receive, accept and acknowledge for and on its behalf, and in respect of its
property, service of any and all legal process, summons, notices and documents
which may be served in any such action or proceeding. If for any reason such
designee, appointee and agent shall cease to be available to act as such, each
Account Party agrees to designate a new designee, appointee and agent in New
York City on the terms and for the purposes of this provision reasonably
satisfactory to the Administrative Agent under this Agreement.

          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.

with the terms of this Agreement and (ii) that the applicable Agent or Lender
shall be responsible for any breach of this Section 10.12 by any of its and its
Affiliates' directors, officers, employees and agents, including accountants,
legal counsel and other advisors), (b) to the extent requested by any regulatory
authority or self-regulatory body, (c) to the extent required by applicable laws
or regulations or by any subpoena or similar legal process, (d) to any other

hereunder or any suit, action or proceeding relating to this Agreement or the
enforcement of rights hereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section, to (i) any assignee
of or Participant in, or any prospective assignee of or Participant in, any of
its rights or obligations under this Agreement or (ii) any actual or prospective

or any Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender issuing or holding participation in
such Letter of Credit or such Loan in accordance with applicable law, the rate
of interest payable in respect of such Letter of Credit or such Loan hereunder,
together with all Charges payable in respect

thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Letter of
Credit or such Loan but were not payable as a result of the operation of this
Section shall be cumulated and the interest and Charges payable to such Lender
in respect of other Letters of Credit or other Loans or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

          SECTION 10.14. USA Patriot Act. Each Lender hereby notifies the
Company and each other Account Party that pursuant to the requirements of the

address of each Account Party and other information that will allow such Lender
to identify each Account Party in accordance with the Patriot Act.
