          (c) In the event that any Fronting Lender makes any payment under any
Fronted Letter of Credit and the respective Borrower shall not have reimbursed
such amount in full to such Fronting Lender pursuant to Section 3.05, 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 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 Borrower
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.

                                      -23-

          (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, without limitation, 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 Borrower 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; or

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

          (vi) any matter or event set forth in subsection 3.05(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 3.03. Conditions to the Issuance of all Letters of Credit. (a)
Notwithstanding anything to the contrary set forth in this Article III, 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 such Letter of Credit in particular or shall impose upon such
     LC Issuer or any Lender with respect to such Letter of Credit any
     restriction or reserve or capital requirement (for which such LC Issuer is
     not otherwise compensated) not in effect on the Effective Date,

                                      -24-

     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 5.02 are not
     satisfied at that time; or

          (iii) such LC Issuer shall have received notice from any Borrower or
     the Required Lenders prior to the issuance of such Letter of Credit of the
     type described in clause (v) of Section 3.03(b).

          (b) Notwithstanding anything to the contrary set forth in this Article
III:

          (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
     Borrower at any time when the Borrowing Base Requirement attributable to
     such Borrower exceed (or would after giving effect to such issuance exceed)
     the Borrowing Base of such Borrower at such time;

          (iii) Reserved;

          (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 each such Letter of Credit (other than the Support Letter of
     Credit) may by its terms automatically renew annually for one additional
     year 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 Borrower or the Required Lenders stating that a
     Default or an Event of Default exists until such time as such LC Issuer
     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.

          (c) Subject to and on the terms and conditions set forth herein, each
LC Issuer is hereby authorized by each Borrower and the Lenders to arrange for
the issuance of any Letter of Credit hereunder and the amendment of any Letter
of Credit pursuant to Section 3.08 and/or 11.02 by:

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

          (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.

          Section 3.04. Letter of Credit Requests. (a) Whenever a Borrower
desires that a Letter of Credit (other than the Support Letter of Credit) be
issued for its account, such Borrower

                                      -25-

shall give the Administrative Agent and the respective LC Issuer written notice
(including by way of facsimile transmission, immediately confirmed in writing by
submission of the original of such request by mail to the Issuing Agent) thereof
prior to 12:00 Noon (New York time) at least three Business Days in respect of
Fronted Letters of Credit prior to the proposed date of issuance (which shall be
a Business Day), which written notice shall be in the form of Exhibit G (each, a
"Letter of Credit Request"). Each Letter of Credit Request shall include any
other documents as the respective LC Issuer customarily requires in connection
therewith.

          (b) The making of each Letter of Credit Request shall be deemed to be
a representation and warranty by the respective Borrower and the Company that
such Letter of Credit may be issued in accordance with, and it will not violate
the requirements applicable to such Borrower and/or such Letter of Credit of,
Section 3.02, as the case may be, and Section 3.03.

          (c) Upon its issuance of, or amendment to, any Letter of Credit, the
respective LC Issuer shall promptly notify the respective Borrower 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 3.05. Agreement to Repay Letter of Credit Drawings. (a) Each
Borrower severally agrees to reimburse 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, an "Unpaid Drawing"), in each case, no later than one Business
Day following the date of such payment or disbursement, 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 equal to the
sum of (x) the Adjusted LIBO Rate as in effect from time to time, plus (y) 3%
(plus an additional 2% per annum, payable on demand, if not reimbursed by the
third Business Day after the date on which the respective Borrower receives
notice from the respective LC Issuer of such payment or disbursement).

          (b) Each Borrower's obligation under this Section 3.05 to reimburse
each Lender with respect to Unpaid Drawings of such Borrower (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 Borrower may have or have had against such Lender, or any LC Issuer,
including, without limitation, 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 Borrower 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 decision).

          (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

                                      -26-

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 decision), shall not create for such LC Issuer any resulting
liability to any Borrower or any of its Affiliates or any Lender.

          Section 3.06. Increased Costs. If any 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 increase the cost to such Lender of issuing,
maintaining or participating in any Letter of Credit, or to reduce the amount of
any sum received or receivable by such Lender hereunder or reduce the rate of
return on its capital with respect to Letters of Credit, then, upon written
demand to the applicable Borrower by such Lender (with a copy to the
Administrative Agent), such Borrower 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 which it is organized or the
jurisdiction in which the principal office or applicable lending office of such
Lender is located 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 3.12 (or would have received
additional amounts pursuant to Section 3.12(e) but for a failure to comply with
Section 3.12(e)). A certificate submitted to the applicable Borrower by such
Lender (with a copy to the Administrative Agent), setting forth (i) the basis
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 Borrower
absent manifest error, although the failure to deliver any such certificate
shall not release or diminish such Borrower's obligations to pay additional
amounts pursuant to this Section 3.06 upon subsequent receipt of such
certificate.

          Section 3.07. Letter of Credit Expiration 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 an additional year, without written amendment, unless at least 30
days (or such other period required under or by any Legal Requirement, Letter of
Credit or Applicable Insurance Regulatory Authority) prior to the expiration
date of such Letter of Credit, 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 (x)
requested to do so by the Required Lenders pursuant to Article VIII or (y) as to
such Letter of Credit only, any outstanding Letter of Credit which would expire,
if automatically extended by its terms for an additional year, on a date after
October 26, 2010. The respective LC Issuer will give Notices of Non-Extension as
to all outstanding Letters of Credit if the Commitment Expiration Date has
occurred. Notwithstanding anything to the contrary contained in this Section
3.07, no LC Issuer shall give a Notice of Non-Extension except as provided in
the

                                      -27-

immediately preceding two sentences. The respective LC Issuer will send a
copy of each Notice of Non-Extension to the respective Borrower concurrently
with delivery thereof to the respective beneficiary, unless prohibited by law
from doing so.

          Section 3.08. Changes to Stated Amount. At any time when any Letter of
Credit (other than the Support Letter of Credit) is outstanding, at the request
of the respective Borrower, the applicable LC Issuer 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 or (y) the Borrowing
Base Requirement attributable to such Borrower to exceed the Borrowing Base of
such Borrower at such time, (ii) the Stated Amount of such Letter of Credit may
not be increased at any time if the conditions precedent set forth in Section
5.02 are not satisfied at such time, and (iii) the Stated Amount of such Letter
of Credit may not be increased at any time after the Commitment Expiration Date.
The Stated Amount of the Support Letter of Credit may be reduced in accordance
with its terms and compliance with Section 3.01(c).

          Section 3.09. 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 $5,000,000 and
not less than $10,000,000 and (ii) the Company shall not terminate or reduce the
Total Commitment if, the Letter of Credit Outstandings would, as a result,
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
3.09 at least 10 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. 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 3.10. Additional Borrowing Base Requirements. If on any date,
the Borrowing Base Requirement attributable to any Borrower exceeds the
Borrowing Base of such Borrower at such time, such Borrower agrees to, within
two Business Days of the date on which the Company or such Borrower receives
notice from the Administrative Agent that the Borrowing Base Requirement
attributable to such Borrower exceeds such Borrower'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 such Borrower hereunder
in the Collateral Account applicable to such Borrower.

                                      -28-

          Section 3.11. Fees. (a) Each Specified Obligor 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 (or if the last day is not a
Business Day, then on the immediately following Business Day) 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 360
days 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 the Administrative Agent, for its own
account, fees payable in the amounts and at the times separately agreed upon in
writing between the Company and the Administrative Agent.

          (c) Each Borrower 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 the Letter of Credit Outstandings attributable
to such Borrower (the "Letter of Credit Fee") computed at a rate per annum equal
to 0.40% on the daily amount of such Letter of Credit Outstandings. 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 (or if the last day is not a
Business Day, then on the immediately following Business Day) and upon the first
day on or after the termination of the Total Commitment upon which no Letters of
Credit remain outstanding.

          (d) Each Borrower severally agrees to pay to each Fronting Lender,
including the Support Lender, for its own account, a fronting fee in respect of
each Fronted Letter of Credit, including the Support Letter of Credit, issued by
such Fronting Lender for the account of such Borrower in an amount and on dates
as shall have separately been agreed in writing to by the Company and such
Fronting Lender.

          (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.

          Section 3.12. Taxes. (a) Any and all payments by or on account of any
obligation of any Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if such
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent 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 Borrower shall make such deductions
and (iii) such Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

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

                                      -29-

          (c) Each Borrower severally (and not jointly) agrees to indemnify the
Administrative Agent and each Lender within 10 days after written demand
therefor, for the full amount of any Indemnified Taxes or Other Taxes that such
Borrower failed to deduct or withhold and that were paid by the Administrative
Agent or such Lender on or with respect to any payment by or on account of any
obligation of such Borrower 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 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 Borrower by a Lender or by the
Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error.

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

          (e) Each Foreign Lender shall 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; provided,
however, that the Company shall have furnished to each such Lender in a
reasonably timely manner copies of such documentation and notice of such
requirements together with applicable instructions; provided, further, that no
such Lender shall have any obligation to provide such documentation or comply
with such requirements if it would result in a material economic, legal or
regulatory disadvantage to any such Lender.

          (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 Borrower or with respect to which such
Borrower has paid additional amounts pursuant to this Section 3.12, it shall pay
over such refund to such Borrower (but only to the extent of indemnity payments
made, or additional amounts paid, by such Borrower under this Section 3.12 with
respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender and without
interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); provided, that such Borrower, upon the request of
the Administrative Agent or such Lender, agrees to repay the amount paid over to
such Borrower (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 Borrower 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 3.12 than such Lender's
assignor could have

                                      -30-

been entitled to absent such assignment except to the extent that the
entitlement to a greater payment resulted from a Change in Law.

          Section 3.13. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) Each Borrower shall make each payment required to be made by it
hereunder (whether of Unpaid Drawings, interest, fees or of amounts payable
under Section 3.06 or 3.12, or otherwise) prior to 12:00 noon, 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 JPMorgan Chase Bank, New York (swift
code CHASUS33, ABA 021 000 021), for the account of ING Bank N.V., London
Branch, Account number 001-1-938123, except that payments pursuant to Sections
3.06, 3.12 and 11.03 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 of any Unpaid Drawing
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 or any fees payable pursuant to Section
3.11 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 Borrower 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 Borrower 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
Unpaid Drawings to any assignee or participant, other than to any Borrower or
any Subsidiary or Affiliate thereof (as to which the provisions of this
paragraph shall apply). Each Borrower 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 Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Borrower
in the amount of such participation.

                                      -31-

          (d) Unless the Administrative Agent shall have received notice from
the relevant Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders hereunder that such Borrower
will not make such payment, the Administrative Agent may assume that such
Borrower 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 Borrower 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 3.02(c) or 3.13(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 Sections until all such
unsatisfied obligations are fully paid.

          Section 3.14. Mitigation Obligations; Replacement of Lenders. (a) If
any Lender requests compensation under Section 3.06, or if each Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 3.12 or Section
3.06, then such Lender shall use reasonable efforts to designate a different
lending office for funding or booking its Unpaid Drawings 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 Sections 3.06 or 3.12,
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 Specified Obligor 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 (x) requests compensation under Section 3.06,
or if each Borrower is required to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Section
3.06 or Section 3.12 or (y) becomes a Defaulting Lender, 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, none of whom shall be a Defaulting Lender at
the time of such replacement (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 11.04), 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 3.14, the Replacement
Lender and the Replaced Lender shall enter into one or more Assignment and
Assumptions pursuant to Section 11.04(b) (and with all fees payable pursuant to
said Section 11.04(b) to be paid by the Replacement Lender) pursuant to which
the Replacement Lender shall acquire all of the Commitments and outstanding
Unpaid Drawings 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)

                                      -32-

an amount equal to the principal amount of, and all accrued but unpaid interest
on, all outstanding Unpaid Drawings of the Replaced Lender, (B) 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 (C) an amount equal to all accrued, but theretofore unpaid, fees
owing to the Replaced Lender pursuant to Section 3.11; (ii) all obligations of
each Borrower 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); (iv) in the
case of any such assignment resulting from payments required to be made pursuant
to Section 3.12, such assignment will result in a reduction in such compensation
or payments; and (v) 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,
and, if so requested by the Replacement Lender, delivery to the Replacement
Lender of the appropriate 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.

          Section 3.15. Removal of Designated Subsidiary Borrowers. The Company
may at any time, upon 10 Business Days prior written notice to the
Administrative Agent, remove a Designated Subsidiary Borrower as a Borrower
hereunder; provided that, (i) the Support Letter of Credit shall have been
terminated or expired, (ii) there shall be no outstanding Letter of Credit
Outstandings attributable to such Designated Subsidiary Borrower, (iii) all
original Letters of Credit issued on behalf of such Designated Subsidiary
Borrower have expired or been returned to the applicable Fronting Lender, (iv)
such Designated Subsidiary Borrower shall have paid accrued and unpaid fees and
expenses attributable to such Designated Subsidiary Borrower pursuant to Section
3.11 or otherwise under this Agreement and (v) no Designated Subsidiary Borrower
shall be deemed removed under this Agreement unless the Administrative Agent has
acknowledged such removal in writing.

qualified and is authorized to do business and is in good standing in all

                                      -33-

          Section 4.02. Corporate Power and Authority. Each Borrower 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

Credit Document to which it is a party and each such Credit Document constitutes
the legal, valid and binding obligation of such Borrower enforceable against
such Borrower 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 4.03. No Contravention of Laws, Agreements or Organizational
Documents. Neither the execution, delivery and performance by any Borrower of

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.

          Section 4.04. Litigation and Contingent Liabilities. There are no
actions, suits or proceedings pending or threatened in writing involving the

letters of credit to secure beneficiaries thereunder for the obligations of such
Borrower under such Reinsurance Agreements and (ii) to secure Indebtedness

Support Letter of Credit issued hereunder is intended to be used solely to
secure the obligations of the Borrowers under the Prior Credit Facility.

          (b) Neither the issuance of any Letter of Credit hereunder, nor the
use of the proceeds thereof, will violate or be inconsistent with the provisions
of Regulation T, U or X and no part of the proceeds of any Letter of Credit will
be used to purchase or carry any Margin Stock or to extend credit for the
purpose of purchasing or carrying any Margin Stock.

          Section 4.06. Approvals. Any order, consent, approval, license,
authorization, or validation of, or filing, recording or registration with, or

governmental or public body or authority, or any subdivision thereof, which is
required to authorize or is required in connection with (i) the execution,
delivery and performance of any Credit Document or (ii) the legality, validity,
binding effect or enforceability of any Credit Document, has been obtained and

          Section 4.09. 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 in writing (including, without limitation,
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 in writing to the Administrative Agent 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 and all filings by the Company with the Securities
and Exchange Commission) not misleading at such time in light of the
circumstances under which such information was provided; provided that, with
respect to projections the Company 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 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.

each Borrower (on an individual basis) and (y) the Company and its Subsidiaries
taken as a whole will, in each case, exceed its debts, (ii) no Borrower will
have incurred or intended to incur debts beyond its ability to pay such debts as
such debts mature and (iii) no Borrower will have unreasonably small capital
with which to conduct its business as conducted on the Effective Date. For

judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
disputed, undisputed, legal, equitable, secured or unsecured; or (ii) right to

investigation, audit or claim now pending or, to the best knowledge of the
Company and its Subsidiaries, proposed or threatened by any authority regarding
any income taxes or any other taxes relating to the Company or any of its
Subsidiaries, which could individually or in the aggregate 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. No tax Liens have been filed and no claims are pending or,

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

existing under or by reason of Legal Requirements, (iii) prohibitions and

                                      -37-

Effect. All required regulatory approvals are in full force and effect on the

a failure to obtain such approval or make such a filing without it being
objected to, could not reasonably be expected to have, either individually or in
the aggregate, a Material Adverse Effect.

          Section 4.19. Security Documents. The Security Documents create, as
security for the obligations hereunder of the Company and each Designated
Subsidiary Borrower, valid and enforceable security interests in and Liens on
all of the Collateral, superior to and prior to the rights of all third persons
and subject to no other Liens. No filings or recordings are required in order to

provision contained in this Agreement, immediately after giving effect to the
pledging of any asset under any Security Document, each Credit Event (and the
satisfaction of all Borrowing Base requirements in connection therewith) and
each Collateral Transfer (as defined in the Security Agreement), each Borrower

hereunder. The fees payable by the Borrowers to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Company and such successor. After the Administrative Agent's
resignation hereunder, the provisions of this Article and Section 11.03 shall
continue in effect for the benefit of such retiring Administrative 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 Administrative
Agent.

          Section 9.12. Collateral Agent Resignation. Subject to the appointment
and acceptance of a successor Collateral Agent as provided in this paragraph,
the Collateral Agent

                                      -61-

in respect of any actions taken or omitted to be taken by any of them while it
was acting as Collateral Agent.

          Section 9.13. Non-Reliance. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement. Each

the Administrative Agent or any other Lender and based on such documents and

own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

                                   ARTICLE X

                                Company Guaranty

          Section 10.01. 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 Borrower to the Guaranteed Creditors.
If any or all of the Guaranteed Obligations of any Designated Subsidiary
Borrower to the Guaranteed Creditors becomes due and payable hereunder, the
Company unconditionally promises to pay such indebtedness to the

                                      -62-

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 Borrower, 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 10.02. Bankruptcy. Additionally, the Company unconditionally
and irrevocably guarantees the payment of any and all of the Guaranteed
Obligations of each Designated Subsidiary Borrower hereunder to the Guaranteed
Creditors whether or not due or payable by each Designated Subsidiary Borrower
upon the occurrence of any of the events specified in Section 8.05 with respect
to such Designated Subsidiary Borrower, and unconditionally promises to pay such
indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money
of the United States.

          Section 10.03. 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 Borrower 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 Borrower 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 Borrower, 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 Borrower, or (e) any payment made to the Guaranteed Creditors on the
Guaranteed Obligations which any such Guaranteed Creditor repays to each
Designated Subsidiary Borrower 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 10.05.

          Section 10.04. Independent Obligation. The obligations of the Company
under this Article X are independent of the obligations of any other guarantor,
any other party or each Designated Subsidiary Borrower, 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 Borrower and whether or not any other guarantor, any other party or
each Designated Subsidiary Borrower 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 X or the enforcement
thereof. Any payment by a

                                      -63-

Designated Subsidiary Borrower or other circumstance which operates to toll any
statute of limitations as to a Designated Subsidiary Borrower shall operate to
toll the statute of limitations as to the Company.

          Section 10.05. Authorization. The obligations of the Company under
this Article X 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 Borrower or others or otherwise act or refrain from
     acting;

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

          (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 Borrower 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 Borrower to the
     Guaranteed Creditors regardless of what liability or liabilities of any
     Designated Subsidiary Borrower 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.

                                      -64-

          Section 10.06. Reliance. It is not necessary for the Guaranteed
Creditors to inquire into the capacity or powers of any Designated Subsidiary
Borrower 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 10.07. Subordination. Any indebtedness of any Designated
Subsidiary Borrower now or hereafter owing to the Company is hereby subordinated
to the Guaranteed Obligations of each Designated Subsidiary Borrower owing to
the Guaranteed Creditors; and if the Administrative Agent so requests at a time
when an Event of Default exists, no Designated Subsidiary Borrower 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
Borrower 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 10.08. 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 Borrower,
any other guarantor or any other party, (ii) proceed against or exhaust any
security held from any Designated Subsidiary Borrower, 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
defense of any Designated Subsidiary Borrower, 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 Borrower, 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 Borrower 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 Borrower 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 Borrower or any other
party or any security.

          (b) The Company waives all presentments, demands for performance,
protests and notices, including, without limitation, notices of non-performance,
notices of protest, notices of dishonor, notices of acceptance of this Company
Guaranty, and notices of the existence,

                                      -65-

creation or incurring of new or additional Guaranteed Obligations. The Company
assumes all responsibility for being and keeping itself informed of each
Designated Subsidiary Borrower'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 10.08 is made with full knowledge of its significance and
consequences, and such waivers shall be effective to the maximum extent
permitted by law.

                                   ARTICLE XI

                                  Miscellaneous

          Section 11.01. Notices. (a) Except in the case of notices and other
communications expressly permitted to be given by telephone (and subject to
paragraph (b) below), all notices and other communications provided for herein
shall be in writing and shall be delivered by hand or overnight courier service,
mailed by certified or registered mail or sent by facsimile, as follows:

     Controller (Facsimile: (441) 294-6390) and (y) with a copy to it at Quanta
     Capital Holdings Ltd., Cumberland House, 1 Victoria Street, Hamilton HM 11,
     Bermuda, Attention: General Counsel (Facsimile: (441) 294-6390;

     opposite its signature below;

          (iii) if to the Administrative Agent, to ING BANK N.V., London Branch,

          (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 III unless otherwise agreed by the
Administrative Agent and the applicable Lender or (y) Section 6.01(d)(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

                                      -66-

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 11.02. 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 Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section 11.02, 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 Borrower, 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 agreements in writing entered into by each Borrower and the
Required Lenders or by each Borrower 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 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, without the
written consent of each Lender affected thereby, (iv) change Section 3.13(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 11.02 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 substantially all of the Collateral
(except as expressly provided in the Credit Documents) under all the Security
Documents or release the Company from the Company Guaranty, without the written
consent of each Lender or (vi) change any provision of Article III 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 the Administrative Agent or any LC Issuer hereunder without the prior written
consent of the Administrative Agent or such LC Issuer, as the case may be.

          Section 11.03. Expenses; Indemnity; Damage Waiver. (a) Each Specified
Obligor jointly and severally agrees to pay (i) all reasonable out-of-pocket
expenses incurred by the Administrative Agent and its Affiliates, including the
reasonable fees, charges and

                                      -67-

disbursements of one counsel for the Administrative Agent, 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), and (ii) all out-of-pocket expenses incurred by
the Administrative Agent, or any Lender, including the fees, charges and
disbursements of any counsel for the Administrative Agent, or any Lender, in
connection with the enforcement or protection 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 Specified Obligor jointly and severally agrees to indemnify
the Administrative Agent, 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 any Borrower or any of its Subsidiaries, or any Environmental
Liability related in any way to any Borrower 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; 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 Borrower fails to pay any amount required
to be paid by it to the Administrative Agent, under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Administrative 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 the Administrative Agent, in its capacity as such.

          (d) To the extent permitted by applicable law, no Borrower shall
assert, and each Borrower 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 issued hereunder or the use of the
proceeds thereof.

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

                                      -68-

          Section 11.04. 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
Borrower 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 Borrower 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 Administrative Agent, 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 banks, investment funds or other
institutions that make or hold commercial loans in the ordinary course of their
businesses all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Unpaid Drawings at the
time owing to it) 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 or Unpaid Drawings, the amount of
          the Commitment or Unpaid Drawings 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; and

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

                                      -69-

               (E) the assignee shall be an NAIC Approved Bank that is not
          either (x) a foreign branch office of a bank or trust company
          organized and existing in the United States or (y) a parent,
          subsidiary or affiliate of any Borrower or any beneficiary under any
          Letter of Credit.

          For the purposes of this Section 11.04(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 Borrower to such
     assignee under Section 3.06 or 3.12 shall be limited to the amount, if any,
     that would have been payable thereunder by such Borrower 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 3.06,
     3.12 and 11.03). Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this Section
     11.04 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 Borrowers, 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 amount of the Unpaid Drawings owing to, each Lender pursuant to the
     terms hereof from time to time (the "Register"). The entries in the
     Register shall be conclusive, and the Borrowers, 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 Borrowers, 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

                                      -70-

     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 Borrower 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 the
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 Borrowers, 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 11.02(b) that
affects such Participant. Subject to paragraph (c)(ii) of this Section, each
Borrower agrees that each Participant shall be entitled to the benefits of
Sections 3.06 and 3.12 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 11.08 as though it were a Lender, provided such Participant
agrees to be subject to Section 3.13(c) as though it were a Lender.

          (ii) A Participant shall not be entitled to receive any greater
payment under Section 3.06 or 3.12 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 3.12 unless the
Company is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrowers, to comply with Section
3.12(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 without limitation 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.

          (e) Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an
"SPC") of such Granting Lender, identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Company, the option
to provide to the applicable Borrower all or any part of any Unpaid Drawings
that such Granting Lender would otherwise be obligated to make to such Borrower
pursuant to Section 3.02(b), provided that (i) nothing herein shall constitute a
commitment to make any funding of an Unpaid Drawing by any SPC and (ii) if an

                                      -71-

SPC elects not to exercise such option or otherwise fails to provide all or any
part of such Loan, the Granting Lender shall be obligated to make such funding
of an Unpaid Drawing pursuant to the terms hereof. The funding of an Unpaid
Drawing by an SPC hereunder shall utilize the Commitment of the Granting Lender
to the same extent, and as if, such Unpaid Drawing was funded by the Granting
Lender. Each party hereto hereby agrees that (x) no SPC shall be liable for any
payment under this Agreement for which a Lender would otherwise be liable and
(y) the Granting Lender for any SPC shall be (and hereby agrees that it is)
liable for any payment under this Agreement for which the SPC would be liable in
the absence of preceding clause (x). In furtherance of the foregoing, each party
hereto hereby agrees that, prior to the date that is one year and one day after
the payment in full of all outstanding senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings or similar proceedings under the laws of the United States or any
State thereof. In addition, notwithstanding anything to the contrary contained
in this Section 11.04 any SPC may (i) with notice to, but without the prior
written consent of, the Company or the Administrative Agent and without paying
any processing fee therefor, assign all or a portion of its interests in any
Unpaid Drawings to its Granting Lender or to any financial institutions (if
consented to by the Company and the Administrative Agent) providing liquidity
and/or credit facilities to or for the account of such SPC to fund the Unpaid
Drawings made by such SPC or to support the securities (if any) issued by such
SPC to fund such Unpaid Drawings and (ii) disclose on a confidential basis any
non-public information relating to its Unpaid Drawings to any rating agency,
commercial paper dealer or provider of a surety, guarantee or credit or
liquidity enhancement to such SPC.

          Section 11.05. Survival. All covenants, agreements, representations
and warranties made by any Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the 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, the
principal of or any accrued interest on any Unpaid Drawing or 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 3.06, 3.12 and 11.03 and Article IX shall
survive and remain in full force and effect regardless of the consummation of
the transactions contemplated hereby, the repayment of the Unpaid Drawings, 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 11.06. 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 5.01, 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

                                      -72-

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 11.07. 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 11.08. 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
Borrower against any of and all the obligations of such Borrower 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 11.09. 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 non-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 Borrower 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

                                      -73-

manner provided for notices in Section 11.01. 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 Borrower hereby irrevocably designates, appoints and empowers
the Service of Process Agent, with offices on the date hereof at 111 Eighth
Avenue, 13th Floor, 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 Borrower 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 11.10. Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

          Section 11.11. 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 11.12. Confidentiality. Each of the Administrative Agent 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 Administrative Agent and each
Lender shall be responsible for any breach of this Section 11.12 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 Borrower 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 the
Administrative

                                      -74-

Agent or any Lender on a non-confidential basis from a source other than the
Company. For the purposes of this Section, "Information" means all information
now or hereafter received from any Borrower relating to the Company, any
Subsidiary of the Company or their respective businesses, other than any such
information that is available to the Administrative Agent or any Lender on a
non-confidential basis prior to disclosure by any Borrower. 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. Notwithstanding anything herein to the contrary, each party to this
Agreement (and any employee, representative or other agent of each such party)
may disclose to any and all persons, without limitation of any kind, the U.S.
federal income tax treatment and the U.S. federal income tax structure of the
transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are provided to it relating to such tax
treatment and tax structure. However, no disclosure of any information relating
to such tax treatment or tax structure may be made to the extent non-disclosure
is reasonably necessary in order to comply with applicable securities laws. The
provisions of this Section 11.12 shall survive the termination of the Total
Commitment (and the Commitment of each Lender) and repayment of all Unpaid
Drawings, each Letter of Credit has expired or been terminated and other
obligations arising hereunder.

          Section 11.13. Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any
Unpaid Drawing, together with all fees, charges and other amounts which are
treated as interest on such Unpaid Drawing 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
holding such Unpaid Drawing, in accordance with applicable law, the rate of
interest payable in respect of such Unpaid Drawing 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 Unpaid Drawing 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 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 11.14. USA Patriot Act. Each Lender hereby notifies the
Company and each other Borrower 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 Borrower, which information includes the name and address
of each Borrower and other information that will allow such Lender to identify
each Borrower in accordance with the Patriot Act.

          Section 11.15. Joint and Several Liability of QRL and QRUSL. QRL and
QRUSL agree, and the Company and the other Designated Subsidiary Borrowers
acknowledge, that QRL and QRUSL shall be jointly and severally liable for their
respective liabilities and obligations under Sections 3.05(a), 3.11(a), (c) and
(d), 3.12(c), 3.14(a) and 11.03(a), (b) and (c). In furtherance and not in
limitation of the foregoing, (i) each of the liabilities and obligations of

                                      -75-

QRL and QRUSL with respect to Letters of Credit issued for its respective
account, and related fees, costs and expenses and (ii) the liabilities and
obligations of QRL and QRUSL arising as result of the joint and several
liability under such Sections of this Agreement with respect to Letters of
Credit issued for the account of the other, together with the related fees,
costs and expenses, shall be separate and distinct obligations, both of which
are primary obligations of such Bermuda Borrower. Neither the joint and several
liability of, nor the Liens granted to the Collateral Agent under the Security
Documents by, either of the Bermuda Borrowers shall be impaired or released by
(A) the failure of the Administrative Agent, any Lender or any Fronting Lender,
any successors or assigns thereof, or any holder of any of the Secured
Obligations (as defined in the Security Agreement) to assert any claim or demand
or to exercise or enforce any right, power or remedy against any Bermuda
Borrower, any other Person, the Collateral or otherwise; (B) any extension or
renewal for any period (whether or not longer than the original period) or
exchange of any of the Secured Obligations of either Bermuda Borrower or the
release or compromise of any obligation of any nature of any Person with respect
thereto; (C) the surrender, release or exchange of all or any part of any
property (including without limitation the Collateral) securing payment,
performance and/or observance of any of the Secured Obligations of either
Bermuda Borrower or the compromise or extension or renewal for any period
(whether or not longer than the original period) of any obligations of any
nature of any Person with respect to any such property; (D) any action or
inaction on the part of the Administrative Agent, any Lender or any Fronting
Lender, or any other event or condition with respect to any other Bermuda
Borrower, including any such action or inaction or other event or condition,
which might otherwise constitute a defense available to, or a discharge of, such
Bermuda Borrower, or a guarantor or surety of or for any or all of the Secured
Obligations; and (E) any other act, matter or thing (other than payment or
performance of the Secured Obligations) which would or might, in the absence of
this provision, operate to release, discharge or otherwise prejudicially affect
the obligations of such Bermuda Borrower or any other Borrower.
