                  SECTION 2.01. (a) Revolving A Advances. Each Lender severally
agrees, on the terms and conditions hereinafter set forth, to make A Advances to
the Borrower from time to time on any Business Day during the period from the
Effective Date to and including the Termination Date in an aggregate amount not
to exceed at any time outstanding the amount set forth opposite such Lender's
name on Schedule III hereto, or, if such Lender has entered into any Assignment
and Acceptance or Commitment Increase Agreement or a New Lender Agreement, set
forth for such Lender in the Register maintained by the Administrative Agent
pursuant to Section 8.07(c), as such amount may be reduced pursuant to Section
2.04 (such Lender's "COMMITMENT"), provided that the aggregate amount of the
Commitments of the Lenders shall be deemed used from time to time to the extent
of the aggregate amount of the B Advances then outstanding and such deemed use
of the aggregate amount of such Commitments shall be applied to all the Lenders
ratably according to their respective Commitments (such deemed use of the
aggregate amount of the Commitments being a "B REDUCTION"). Each A Borrowing

Commitments, if less) and shall consist of A Advances of the same Type made on
the same day by the Lenders ratably according to their respective Commitments.
Within the limits of each Lender's Commitment, the Borrower may make more than
one Borrowing on any Business Day and may borrow, prepay pursuant to Section
2.10, and reborrow under this Section 2.01(a).

                  SECTION 2.02. Making the A Advances. (a) Each A Borrowing
shall be made on notice by the Borrower to the Administrative Agent (a "NOTICE
OF A BORROWING") received by the Administrative Agent, (i) in the case of a
proposed A Borrowing comprised of Base Rate Advances, not later than 10:00 A.M.
(New York City time) on the Business Day of such proposed A Borrowing, and (ii)
in the case of a proposed A Borrowing comprised of Eurodollar Rate Advances, not
later than 12:00 noon (New York City time) on the third Business Day prior to
the date of such proposed A Borrowing. Each Notice of A Borrowing shall be by
telecopy, telefax or other teletransmission or by telephone (and if by
telephone, confirmed promptly by telecopier, telefax or other teletransmission),
in substantially the form of Exhibit B hereto, specifying therein the requested
(w) date of such A Borrowing, (x) Type of A Advances comprising such A Borrowing
and, additionally, whether such A Borrowing consists of Revolving A Advances or
Term A Advances, (y) aggregate amount of such A Borrowing, and (z) in the case
of an A Borrowing comprised of Eurodollar Rate Advances, the initial Interest
Period for each such A Advance. Each Lender shall, before 1:00 p.m. (New York
City time) on the date of such A Borrowing, make available for the account of
its Applicable Lending Office to the Administrative Agent in care of JPMorgan
Chase Bank, Loan and Agency Services, 1111 Fannin, 10th Floor, Houston, Texas
77002, Attention: Karla Contreras, Reference: Burlington Resources Inc., or at
such other location designated by notice from the Administrative Agent to the
Lenders pursuant to Section 8.02, in same day funds, such Lender's ratable
portion of such A Borrowing. Immediately after the Administrative Agent's
receipt of such funds and upon fulfillment of the applicable conditions set
forth in Article 3, the Administrative Agent will make such funds available to
the Borrower at JPMorgan Chase Bank, One Chase Manhattan Plaza, 8th Floor, New
York, NY 10081, or at any account of the Borrower maintained by the
Administrative Agent (or any successor Administrative Agent) designated by the
Borrower and agreed to by the Administrative Agent (or such successor
Administrative Agent), in same day funds.

                  (b) Each Notice of A Borrowing shall be irrevocable and
binding on the Borrower. In the case of any A Borrowing which the related Notice
of A Borrowing specified is to be comprised of Eurodollar Rate Advances, if such
A Advances are not made as a result of any failure to fulfill on or before the
date specified for such A Borrowing the applicable conditions set forth in
Article 3, the Borrower shall indemnify each Lender against any loss, cost or
expense incurred by such Lender as a result of such failure, including any loss,
cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Lender to fund the A Advance to be made
by such Lender as part of such A Borrowing.

                  (c) If any Lender makes a Term A Advance to the Borrower
hereunder on a day on which the Borrower is to repay all or any part of an
outstanding Revolving A Advance from such Lender, such Lender shall apply the
proceeds of its Term A Advance to make such repayment and only an amount equal
to the difference (if any) between the amount being borrowed and the amount
being repaid shall be made available by such Lender to the Administrative Agent
as provided in subsection 2.02(a), or remitted by the Borrower to the
Administrative Agent as provided in Section 2.14, as the case may be.

                                                                              21

                  (d) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any A Borrowing that such Lender will not
make available to the Administrative Agent such Lender's ratable portion of such
A Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such A Borrowing in
accordance with subsections (a) and (c) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent, at the Effective Federal Funds Rate for such day. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount so
repaid shall constitute such Lender's A Advance to the Borrower as part of such
A Borrowing for purposes of this Agreement.

                  (e) The failure of any Lender to make the A Advance to be made
by it as part of any A Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its A Advance on the date of such A
Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make the A Advance to be made by such other Lender on the date of any
A Borrowing.

                  SECTION 2.03. Fees. (a) FACILITY FEE. The Borrower agrees to
pay to the Administrative Agent for the account of each Lender (other than a
Designated Bidder) a facility fee on the average daily amount of such Lender's
Commitment, whether or not used or deemed used, from the Effective Date in the
case of each Initial Lender and from the effective date specified in the
Assignment and Acceptance or Commitment Increase Agreement pursuant to which it
became a Lender in the case of each other Lender, in each case until the
Termination Date, payable quarterly in arrears on the last day of each March,
June, September and December during the term of such Lender's Commitment and on
the Termination Date, at a rate per annum equal to the Facility Fee Percentage

                  (b) UTILIZATION FEE. The Borrower agrees to pay to the
Administrative Agent for the account of each Lender (i) for any Utilization Fee
Period, if during such Utilization Fee Period the Average Aggregate Facility
Advances were greater than 25% and less than or equal to 50% of the Average
Aggregate Facility Commitments, a utilization fee of 0.125% per annum on the
average daily amount of such Lender's Advances during such Utilization Fee
Period; and (ii) for any Utilization Fee Period, if during such Utilization Fee
Period the Average Aggregate Facility Advances were greater than 50% of the
Average Aggregate Facility Commitments, a utilization fee of 0.25% per annum on
the average daily amount of such Lender's Advances during such Utilization Fee
Period. If a utilization fee is owing in respect of any Utilization Fee Period,
such fee shall be payable on the last day of such Utilization Fee Period.

per annum on the average daily amount of the outstanding principal amount of

last day of each March, June, September and December and on the date on which

Administrative Agent, for its own account, such agency fees as may be separately

and the Borrower.

have the right, upon at least three Business Days' notice to the Administrative
Agent, to terminate in whole or reduce ratably in part the unused portions of
the Commitments of the Lenders (being the amount by which such Commitments
exceed the aggregate outstanding principal amount of all Advances), provided
that each partial reduction shall be in the aggregate amount of $20,000,000 or
any whole multiple of $1,000,000 in excess thereof.

                  SECTION 2.05. Repayment of A Advances. (a) The Borrower shall

the Board of Governors of the Federal Reserve System are required to be
maintained by it in respect of, or a portion of its costs of maintaining
reserves under such regulations is properly attributable to, one or more of its
Eurodollar Rate Advances, the Borrower shall pay to such Lender additional
interest on the unpaid principal amount of each such Eurodollar

<PAGE>

                                                                              24

Rate Advance payable on the same day or days on which interest is payable on
such A Advance, at an interest rate per annum up to but not exceeding at all
times during each Interest Period for such A Advance the excess of (i) the rate
obtained by dividing the Eurodollar Rate for such Interest Period by a
percentage equal to 100% minus the Eurodollar Reserve Percentage, if any, for
such Lender for such Interest Period over (ii) the Eurodollar Rate for such
Interest Period. Any Lender wishing to require payment of such additional
interest (x) shall so notify the Borrower and the Administrative Agent, in which
case such additional interest on the Eurodollar Rate Advances of such Lender
shall be payable to such Lender at the place indicated in such notice with
respect to each Interest Period commencing at least five Business Days after the
giving of such notice and (y) shall furnish to the Borrower at least five
Business Days prior to each date on which interest is payable on the Eurodollar
Rate Advances an officer's certificate setting forth the amount to which such
Lender is then entitled under this Section, which certificate shall be
conclusive and binding for all purposes, absent manifest error.

                  SECTION 2.08. Interest Rate Determination. (a) The
Administrative Agent shall give prompt notice to the Borrower and the Lenders of
the applicable interest rate determined by the Administrative Agent for purposes
of Section 2.06(a)(i) or (ii), and, if any, the applicable interest rate under
Section 2.06(a)(iii).

                  (b) If, with respect to any Eurodollar Rate Advances, the
Majority Lenders determine and give notice to the Administrative Agent that as a
result of conditions in or generally affecting the relevant market, the rates of
interest determined on the basis of the Eurodollar Rate for any Interest Period
for such A Advances will not adequately reflect the cost to such Majority
Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Administrative Agent shall forthwith so
notify the Borrower and the Lenders, whereupon:

                  (i) each such Eurodollar Rate Advance will automatically, on
         the last day of the then existing Interest Period therefor, Convert
         into a Base Rate Advance, and

                  (ii) the obligation of the Lenders to make, or to Convert A
         Advances into, Eurodollar Rate Advances shall be suspended until the
         Administrative Agent shall notify the Borrower and the Lenders that the
         circumstances causing such suspension no longer exist.

                  (c) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Lenders and
such Eurodollar Rate Advances will automatically, on the last day of the then
existing Interest Period therefor, Convert into Eurodollar Rate Advances with an
Interest Period of one month.

                  (d) On the date on which the aggregate unpaid principal amount
of A Advances comprising any A Borrowing shall be reduced, by payment or
prepayment or otherwise, to less than $10,000,000, such A Advances shall, if
they are Eurodollar

<PAGE>

                                                                              25

Rate Advances, automatically Convert into Base Rate Advances, and on and after
such date the right of the Borrower to Convert such A Advances into Eurodollar
Rate Advances shall terminate; provided, however, that if and so long as each
such A Advance shall be, or be elected to be Converted to, Eurodollar Rate
Advances having the same Interest Period as Eurodollar Rate Advances comprising
another A Borrowing or other A Borrowings, and the aggregate unpaid principal
amount of all such Eurodollar Rate Advances shall, or upon such Conversion will,
equal or exceed $20,000,000, the Borrower shall have the right to continue all
such Eurodollar Rate Advances as, or to Convert all such A Advances into,
Eurodollar Rate Advances having such Interest Period.

                  SECTION 2.09. Voluntary Conversion of A Advances. The Borrower
may on any Business Day, upon notice given to the Administrative Agent, not
later than 12:00 noon (New York City time) on the third Business Day prior to
the date of the proposed Conversion, and subject to the provisions of Section
2.08, 2.11 and 2.13, Convert all A Advances of one Type comprising the same A
Borrowing into A Advances of the other Type; provided, however, that any
Conversion of any Eurodollar Rate Advances into Base Rate Advances made on any
day other than the last day of an Interest Period for such Eurodollar Rate
Advances shall be subject to the provisions of Section 8.04(b). Each such notice
of a Conversion shall, within the restrictions specified above, specify (i) the
date of such Conversion, (ii) the A Advances to be Converted, and (iii) if such
Conversion is into Eurodollar Rate Advances, the duration of the Interest Period
for each such Eurodollar Rate Advance.

                  SECTION 2.10. Prepayments. The Borrower may, upon (i) in the
case of Eurodollar Rate Advances, at least three Business Days notice or (ii) in
the case of Base Rate Advances, telephonic notice not later than 12:00 noon (New
York City time) on the date of prepayment, to the Administrative Agent which
specifies the proposed date and aggregate principal amount of the prepayment and
the Type of A Advances to be prepaid, and if such notice is given the Borrower
shall, prepay the outstanding principal amounts of the A Advances comprising the
same A Borrowing in whole or ratably in part, together with accrued interest to
the date of such prepayment on the amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount not less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of Eurodollar Rate Advances on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances, the
Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant
to, and to the extent required by, Section 8.04(b); provided, further, however,
that the Borrower will use its best efforts to give notice to the Administrative
Agent of the proposed prepayment of Base Rate Advances on the Business Day prior
to the date of such proposed prepayment.

                  SECTION 2.11. Increased Costs. (a) If, due to either (i) the
introduction after the Effective Date of or any change after the Effective Date
(including any change by way of imposition or increase of reserve requirements
or assessments other than those referred to in the definition of "Eurodollar
Reserve Percentage" contained in Section 1.01) in or in the interpretation of
any law or regulation or (ii) the compliance with any guideline or request
issued or made after the Effective Date from or by any central bank or other
governmental authority (whether or not having the force of law), in

<PAGE>

                                                                              26

each case above other than those referred to in Section 2.12, there shall be any
increase in the cost to any Lender of agreeing to make, fund or maintain, or of
making, funding or maintaining, Eurodollar Rate Advances funded in the interbank
Eurodollar market, then the Borrower shall from time to time, upon demand by
such Lender (with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender additional amounts
sufficient to reimburse such Lender for all such increased costs (except those
incurred more than 60 days prior to the date of such demand; for the purposes
hereof any cost or expense allocable to a period prior to the publication or
effective date of such an introduction, change, guideline or request shall be
deemed to be incurred on the later of such publication or effective date). Each
Lender agrees to use its best reasonable efforts promptly to notify the Borrower
of any event referred to in clause (i) or (ii) above, provided that the failure
to give such notice shall not affect the rights of any Lender under this Section
2.11(a) (except as otherwise expressly provided above in this Section 2.11(a)).
A certificate as to the amount of such increased cost, submitted to the Borrower
and the Administrative Agent by such Lender, shall be conclusive and binding for
all purposes, absent manifest error. After one or more Lenders have notified the
Borrower of any increased costs pursuant to this Section 2.11, the Borrower may
specify by notice to the Administrative Agent and the affected Lenders that,
after the date of such notice whenever the election of a Eurodollar Rate Advance
by the Borrower for an Interest Period or portion thereof would give rise to
such increased costs, such election shall not apply to the A Advances of such
Lender or Lenders during such Interest Period or portion thereof, and, in lieu
thereof, such A Advances shall during such Interest Period or portion thereof be
Base Rate Advances. Each Lender agrees to use its best reasonable efforts
(including a reasonable effort to change its Applicable Lending Office or to
transfer its affected A Advances to an Affiliate of such Lender) to avoid, or
minimize the amount of, any demand for payment from the Borrower under this
Section 2.11, provided that such avoidance would not, in the reasonable judgment
of such Lender, be otherwise disadvantageous to such Lender.

                  (b) In the event that any Lender shall change its Eurodollar
Lending Office and such change results (at the time of such change) in increased
costs to such Lender, the Borrower shall not be liable to such Lender for such
increased costs incurred by such Lender to the extent, but only to the extent,
that such increased costs shall exceed the increased costs which such Lender
would have incurred if the Eurodollar Lending Office of such Lender had not been
so changed, but, subject to subsection (a) of this Section 2.11 and to Section
2.13, nothing herein shall require any Lender to change its Eurodollar Lending
Office for any reason.

                  SECTION 2.12. Increased Capital. If either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) compliance by any Lender with any guideline or request from
any central bank or other governmental authority (whether or not having the
force of law) affects or would affect the amount of capital required or expected
to be maintained by such Lender or any corporation controlling such Lender
(including any determination after the Effective Date by any such central bank,
governmental authority or comparable agency that, for purposes of capital
adequacy requirements, the Commitments hereunder do not constitute commitments
with an original maturity of one year or less) and such Lender determines

<PAGE>

                                                                              27

that the amount of such capital is increased by or based upon the existence of
such Lender's commitment to lend hereunder and other commitments of this type,
then, within ten days after demand, and delivery to the Borrower of the
certificate referred to in the last sentence of this Section 2.12 by such Lender
(with a copy of such demand to the Administrative Agent), the Borrower shall pay
to the Administrative Agent for the account of such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender or such corporation in the light of such circumstances, to the extent
that such Lender reasonably determines such increase in capital to be allocable
to the existence of such Lender's commitment to lend hereunder (except any such
increase in capital incurred more than, or compensation attributable to the
period before, 90 days prior to the date of such demand; for the purposes hereof
any increase in capital allocable to, or compensation attributable to, a period
prior to the publication or effective date of such an introduction, change,
guideline or request shall be deemed to be incurred on the later of such
publication or effective date). Each Lender agrees to use its best reasonable
efforts promptly to notify the Borrower of any event referred to in clause (i)
or (ii) above, provided that the failure to give such notice shall not affect
the rights of any Lender under this Section 2.12 (except as otherwise expressly
provided above in this Section 2.12). A certificate in reasonable detail as to
the basis for, and the amount of, such compensation submitted to the Borrower
and the Administrative Agent by such Lender shall, in the absence of manifest
error, be conclusive and binding for all purposes.

                  SECTION 2.13. Illegality. Notwithstanding any other provision
of this Agreement, if the introduction of or any change in or in the
interpretation of any law or regulation shall make it unlawful, or any central
bank or other governmental authority shall assert that it is unlawful, for any
Lender or its Applicable Lending Office to perform its obligations hereunder to
make Eurodollar Rate Advances or to continue to fund or maintain such Advances
hereunder, such Lender may, by notice to the Borrower and the Administrative
Agent, suspend the right of the Borrower to elect Eurodollar Rate Advances from
such Lender and, if necessary in the reasonable opinion of such Lender to comply
with such law or regulation, Convert all such Eurodollar Rate Advances of such
Lender to Base Rate Advances at the latest time permitted by the applicable law
or regulation, and such suspension and, if applicable, such Conversion shall
continue until such Lender notifies the Borrower and the Administrative Agent
that the circumstances making it unlawful for such Lender to perform such
obligations no longer exist (which such Lender shall promptly do when such
circumstances no longer exist). So long as the obligation of any Lender to make
Eurodollar Rate Advances has been suspended under this Section 2.13, all Notices
of A Borrowing specifying A Advances of such Type shall be deemed, as to such
Lender, to be requests for Base Rate Advances. Each Lender agrees to use its
best reasonable efforts (including a reasonable effort to change its Applicable
Lending Office or to transfer its affected A Advances to an affiliate) to avoid
any such illegality, provided that such avoidance would not, in the reasonable
judgment of such Lender, be otherwise disadvantageous to such Lender.

                  SECTION 2.14. Payments and Computations. (a) The Borrower
shall make each payment hereunder (including under Section 2.03, 2.05, 2.06 or
2.19) and under the Notes, whether the amount so paid is owing to any or all of
the Lenders or to

<PAGE>

                                                                              28

the Administrative Agent, not later than 1:00 P.M. (New York City time) without
setoff, counterclaim, or any other deduction whatsoever, on the day when due in
U.S. dollars to the Administrative Agent in care of JPMorgan Chase Bank, Loan
and Agency Services, 1111 Fannin, 10th Floor, Houston, Texas 77002, Attention:
Karla Contreras, Reference: Burlington Resources Inc., or at such other location
designated by notice to the Borrower from the Administrative Agent and agreed to
by the Borrower, in same day funds. Each such payment made by the Borrower for
the account of any Lender hereunder, when so made to the Administrative Agent,
shall be deemed duly made for all purposes of this Agreement and the Notes,
except that if at any time any such payment is rescinded or must otherwise be
returned by the Administrative Agent or any Lender upon the bankruptcy,
insolvency or reorganization of the Borrower or otherwise, such payment shall be
deemed not to have been so made. The Administrative Agent will promptly
thereafter cause to be distributed like funds relating to the payment of
principal or interest or fees ratably (other than amounts payable pursuant to
Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b)) to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(d), from and after the effective date
specified in such Assignment and Acceptance, the Administrative Agent shall make
all payments hereunder and under the Notes in respect of the interest assigned
thereby to the Lender assignee thereunder, and the parties to such Assignment
and Acceptance shall make all appropriate adjustments in such payments for
periods prior to such effective date directly between themselves.

                  (b) All computations of interest based on the Base Rate and of
facility fees and utilization fees (or amounts in lieu thereof) shall be made by
the Administrative Agent on the basis of a year of 365 or 366 days, as the case
may be, and all computations of interest based on the Eurodollar Rate, or the
Effective Federal Funds Rate shall be made by the Administrative Agent, and all
computations of interest pursuant to Section 2.07 shall be made by each Lender
with respect to its own Eurodollar Rate Advances, on the basis of a year of 360
days, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or fees
are payable. Each determination by the Administrative Agent (or, in the case of
Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b), by each Lender with
respect to its own Advances) of an interest rate or an increased cost, loss or
expense or increased capital or of illegality or taxes hereunder shall be
conclusive and binding for all purposes if made reasonably and in good faith.

                  (c) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or facility fees, as
the case may be; provided, however, if such extension would cause payment of
interest on or principal of Eurodollar Rate Advances to be made in the next
following calendar month, such payment shall be made on the next preceding
Business Day.

<PAGE>

                                                                              29

                  (d) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to the Lenders
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent the Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at a rate equal to the Effective Federal Funds Rate for such day.

                  SECTION 2.15. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made in accordance with Section 2.14, free
and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding in the case of each Indemnified Party, (i) all taxes,
levies, imposts, deductions, charges, or withholdings, and all liabilities with
respect thereto, imposed on or determined by reference to its income or profits,
and all franchise taxes, and (ii) all other taxes, levies, imposts, deductions,
charges, or withholdings in effect at the time that such Indemnified Party
executed this Agreement or otherwise became an "Indemnified Party" hereunder,
and liabilities with respect thereto, imposed on it by reason of the
jurisdiction in which such Indemnified Party is organized, domiciled, resident
or doing business, or any political subdivision thereof, or by reason of the
jurisdiction of its Applicable Lending Office or any other office from which it
makes or maintains any extension of credit hereunder or any political
subdivision thereof (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities in respect of payments under this
Agreement or under the Notes being herein referred to as "TAXES"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note to any Indemnified Party, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.15) such Indemnified Party receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower (or the
Administrative Agent, as applicable) shall make such deductions at the
applicable statutory rate and (iii) the Borrower (or the Administrative Agent,
as applicable) shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law, provided that
the Borrower shall not be required to pay any additional amount (and shall be
relieved of any liability with respect thereto) pursuant to this subsection (a)
(or pursuant to Section 2.15(c), except to the extent Section 2.15(c) relates to
Other Taxes) to any Indemnified Party that either (x) on the date such
Indemnified Party executed this Agreement or otherwise became an "Indemnified
Party" hereunder, both (A) was not entitled to submit a U.S. Internal Revenue
Service form W-8BEN (relating to such Indemnified Party, and entitling it to a
complete exemption from withholding on all amounts to be received by such
Indemnified Party, including fees, pursuant to this Agreement or the Advances)
or a U.S. Internal Revenue Service form W-8ECI (relating

<PAGE>

                                                                              30

to all amounts to be received by such Indemnified Party, including fees,
pursuant to this Agreement and the Advances) and (B) is not a United States
person (as such term is defined in Section 7701(a)(30) of the Internal Revenue
Code), or (y) has failed to submit any form or certificate that it was required
to file or provide pursuant to subsection (d) of this Section 2.15 and is
entitled to file or give, as applicable, under applicable law, provided,
further, that should an Indemnified Party become subject to Taxes because of its
failure to deliver a form required hereunder, the Borrower shall take such
administrative steps as such Indemnified Party shall reasonably request to
assist such Indemnified Party to recover such Taxes, and provided further, that
each Indemnified Party, with respect to itself, agrees to indemnify and hold
harmless the Borrower from any taxes, penalties, interest and other expenses,
costs and losses incurred or payable by the Borrower as a result of the failure
of the Borrower to comply with its obligations under clauses (ii) or (iii) above
in reliance on any form or certificate provided to it by such Indemnified Party
pursuant to this Section 2.15. If any Indemnified Party receives a net credit or
refund in respect of such Taxes or amounts so paid by the Borrower, it shall
promptly notify the Borrower of such net credit or refund and shall promptly pay
such net credit or refund to the Borrower, provided that the Borrower agrees to
return such net credit or refund if the Indemnified Party to which such net
credit or refund is applicable, is required to repay it.

                  (b) In addition, the Borrower agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies which arise from any payment made hereunder or under the Notes
or from the execution, delivery or registration of, or otherwise with respect
to, this Agreement or the Notes (hereinafter referred to as "OTHER TAXES").

                  (c) The Borrower will indemnify each Indemnified Party for the
full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed
by any jurisdiction on amounts payable under this Section 2.15) paid by such
Indemnified Party and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto except as a result of the gross
negligence (which shall in any event include the failure of such Indemnified
Party to provide to the Borrower any form or certificate that it was required to
provide pursuant to subsection (d) below) or willful misconduct of such
Indemnified Party, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date such Indemnified Party makes written demand therefor.

                  (d) On or prior to the date on which each Indemnified Party
that is not a United States person (as such term is defined in Section
7701(a)(30) of the Internal Revenue Code) executes this Agreement or otherwise
becomes an "Indemnified Party" hereunder, such Indemnified Party shall provide
the Borrower and the Administrative Agent with U.S. Internal Revenue Service
form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the
U.S. Internal Revenue Service, certifying that such Indemnified Party is fully
exempt from United States withholding taxes with respect to all payments to be
made to such Indemnified Party hereunder, or other documents satisfactory to the
Borrower indicating that all payments to be made to such Indemnified Party
hereunder are fully exempt from such taxes. Thereafter and from time to time,
each

<PAGE>

                                                                              31

such Indemnified Party shall submit to the Borrower and the Administrative Agent
such additional duly completed and signed copies of one or the other of such
forms (or such successor forms as shall be adopted from time to time by the
relevant United States taxing authorities) as may be (i) notified by the
Borrower to such Indemnified Party and (ii) required under then-current United
States law or regulations to avoid United States withholding taxes on payments
in respect of all amounts to be received by such Indemnified Party pursuant to
this Agreement or the Notes, including fees. Upon the request of the Borrower
from time to time, each Indemnified Party that is a United States person (as
such term is defined in Section 7701(a)(30) of the Internal Revenue Code) shall
submit to the Borrower a certificate to the effect that it is such a United
States person. If any Indemnified Party determines, as a result of any change in
applicable law, regulation or treaty, or in any official application or
interpretation thereof, that it is unable to submit to the Borrower any form or
certificate that such Indemnified Party is obligated to submit pursuant to this
subsection (d), or that such Indemnified Party is required to withdraw or cancel
any such form or certificate previously submitted, such Indemnified Party shall
promptly notify the Borrower and the Administrative Agent of such fact.

                  (e) Any Indemnified Party claiming any additional amounts
payable pursuant to this Section 2.15 shall use its best reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Applicable Lending Office if the making of such a
change would avoid the need for, or reduce the amount of, any such additional
amounts which may thereafter accrue and would not, in the reasonable judgment of
such Indemnified Party, be otherwise disadvantageous to such Indemnified Party.

                  (f) Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower and
each Indemnified Party contained in this Section 2.15 shall survive the payment
in full of principal and interest hereunder and under the Notes.

                  SECTION 2.16. Sharing of Payments, Etc. If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the A Advances made by it (other
than pursuant to Section 2.07, 2.11, 2.12, 2.13, 2.15 or 8.04(b)) in excess of
its ratable share of payments on account of the A Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the A Advances made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and each Lender shall repay to the purchasing Lender the
purchase price to the extent of such Lender's ratable share (according to the
proportion of (i) the amount of the participation purchased from such Lender as
a result of such excess payment to (ii) the total amount of such excess payment)
of such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (A) the amount of such Lender's required
repayment to (B) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so

                                                                              32

purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

                  SECTION 2.17. Evidence of Debt. (a) Each Lender shall maintain
in accordance with its usual practice an account or accounts evidencing the
Indebtedness of the Borrower to such Lender resulting from each Advance made by
such Lender hereunder, including the amounts of principal and interest payable
and paid to such lender from time to time hereunder.

                  (b) The Administrative Agent shall maintain accounts and
records in which it shall record (i) the amount of each Advance made hereunder,
the type of Advance and, in the cases of Eurodollar Rate Advances, the relevant
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder, and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender's share thereof.

                  (c) The entries made in the accounts maintained pursuant to
Sections 2.17(a) and (b) shall be conclusive evidence (absent manifest error) of
the existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Advances in accordance with the terms of this Agreement. In the
event of a conflict between the records maintained by the Administrative Agent
and any Lender, the records maintained by the Lender shall govern. Any Lender
may request that Loans made by it be evidenced by a Note. In such event, the
Borrower shall prepare, execute and deliver to such Lender a Note payable to the
order of such Lender (or, if requested by such Lender, to such Lender and its
registered assigns) and substantially in the form attached as Exhibit A hereto.
Thereafter, the Loans evidenced by such Note and interest thereon shall at all
times (including after assignment pursuant to Section 8.07) be represented by
one or more Notes in such form payable to the order of the payee named therein
(or, if such Note is a registered Note, to such payee and its registered
assigns).

                  SECTION 2.18. Use of Proceeds. Proceeds of the Advances may be
used for general corporate purposes of the Borrower and its Subsidiaries,
including for acquisitions and for payment of commercial paper issued by the
Borrower.

                  SECTION 2.19. The B Advances. (a) Each Lender severally agrees
that the Borrower may make B Borrowings under this Section 2.19 from time to
time on any Business Day during the period from the Effective Date until the
earlier of (I) the Termination Date or (II) the date falling 30 days prior to
the Stated Termination Date, in the manner set forth below; provided that (x)
each B Borrowing shall be in an aggregate amount of $25,000,000 or an integral
multiple of $5,000,000 in excess thereof and (y) following the making of each B
Borrowing, the aggregate number of outstanding B Borrowings shall not exceed
seven and the aggregate amount of all Advances then

                                                                              33

outstanding shall not exceed the aggregate amount of the Commitments of the
Lenders (computed without regard to any B Reduction).

                  (i) The Borrower may request a B Borrowing under this Section
         2.19 by delivering to the Administrative Agent, by telecopy, telefax or
         other teletransmission, a notice of a B Borrowing (a "NOTICE OF B
         BORROWING"), in substantially the form of Exhibit C hereto, specifying
         the date and aggregate amount of the proposed B Borrowing, the maturity
         date for repayment of each B Advance to be made as part of such B
         Borrowing (which maturity date may not be earlier than the date
         occurring 30 days after the date of such B Borrowing or later than the
         earlier of (x) 180 days after the date of such B Borrowing or (y) the
         Stated Termination Date), the interest payment date or dates relating
         thereto, and any other terms to be applicable to such B Borrowing, not
         later than 10:00 A.M. (New York City time) (A) at least one Business
         Day prior to the date of the proposed B Borrowing, if the Borrower
         shall specify in the Notice of B Borrowing that the rates of interest
         to be offered by the Lenders shall be fixed rates per annum and (B) at
         least four Business Days prior to the date of the proposed B Borrowing,
         if the Borrower shall instead specify in the Notice of B Borrowing the
         basis to be used by the Lenders in determining the rates of interest to
         be offered by them. The Administrative Agent shall in turn promptly
         notify each Lender of each request for a B Borrowing received by it
         from the Borrower by sending such Lender a copy of the related Notice
         of B Borrowing.

                  (ii) Each Lender may, if in its sole and absolute discretion
         it elects to do so, irrevocably offer to make one or more B Advances to
         the Borrower as part of such proposed B Borrowing at a rate or rates of
         interest specified by such Lender in its sole discretion, by notifying
         the Administrative Agent (which shall give prompt notice thereof to the
         Borrower), before 10:00 A.M. (New York City time) (x) on the date of
         such proposed B Borrowing in the case of a Notice of B Borrowing
         delivered pursuant to clause (A) of paragraph (i) above, and (y) three
         Business Days before the date of such proposed B Borrowing in the case
         of a Notice of B Borrowing delivered pursuant to clause (B) of
         paragraph (i) above, of the maximum amount of each B Advance which such
         Lender would be willing to make as part of such proposed B Borrowing
         (which amount may, subject to clause (y) of the proviso to the first
         sentence of this Section 2.19(a), exceed such Lender's Commitment), the
         rate or rates of interest therefor and such Lender's Applicable Lending
         Office with respect to such B Advance; provided that if the
         Administrative Agent or an Affiliate thereof in its capacity as a
         Lender shall, in its sole discretion, elect to make any such offer, it
         shall notify the Borrower of such offer before 9:45 A.M. (New York City
         time) on the date on which notice of such election is to be given to
         the Administrative Agent by the other Lenders. If any Lender shall
         elect not to make such an offer, such Lender shall so notify the
         Administrative Agent, before 10:00 A.M. (New York City time) on the
         date on which notice of such election is to be given to the
         Administrative Agent by the other Lenders, and such Lender shall not be
         obligated to, and shall not, make any B Advance as part of such B
         Borrowing; provided that the failure by any

                                                                              34

         Lender to give such notice shall not cause such Lender to be obligated
         to make any B Advance as part of such proposed B Borrowing.

                  (iii) The Borrower shall, in turn, before 11:00 A.M. (New York
         City time) (x) on the date of such proposed B Borrowing, in the case of
         a Notice of B Borrowing delivered pursuant to clause (A) of paragraph
         (i) above and (y) three Business Days before the date of such proposed
         B Borrowing in the case of a Notice of B Borrowing delivered pursuant
         to clause (B) of paragraph (i) above, either

                           (A) cancel such B Borrowing by giving the
                  Administrative Agent notice to that effect, or

                           (B) accept one or more of the offers made by any
                  Lender or Lenders pursuant to paragraph (ii) above, in order
                  of the lowest to highest rates of interest or margins (or, if
                  two or more Lenders bid at the same rates of interest, and the
                  amount of accepted offers is less than the aggregate amount of
                  such offers, the amount to be borrowed from such Lenders as
                  part of such B Borrowing shall be allocated among such Lenders
                  pro rata on the basis of the maximum amount offered by such
                  Lenders at such rates or margin in connection with such B
                  Borrowing), in any aggregate amount up to the aggregate amount
                  initially requested by the Borrower in the relevant Notice of
                  B Borrowing, by giving notice to the Administrative Agent of
                  the amount of each B Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the
                  Administrative Agent on behalf of such Lender for such B
                  Advance pursuant to paragraph (ii) above) to be made by each
                  Lender as part of such B Borrowing, and reject any remaining
                  offers made by Lenders pursuant to paragraph (ii) above by
                  giving the Administrative Agent notice to that effect.

                  (iv) If the Borrower notifies the Administrative Agent that
         such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the
         Administrative Agent shall give prompt notice thereof to the Lenders
         and such B Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to paragraph (iii)(B) above, the
         Administrative Agent shall in turn promptly notify (A) each Lender that
         has made an offer as described in paragraph (ii) above, of the date and
         aggregate amount of such B Borrowing and whether or not any offer or
         offers made by such Lender pursuant to paragraph (ii) above have been
         accepted by the Borrower, (B) each Lender that is to make a B Advance
         as part of such B Borrowing, of the amount of each B Advance to be made
         by such Lender as part of such B Borrowing, and (C) each Lender that is
         to make a B Advance as part of such B Borrowing, upon receipt, that the
         Administrative Agent has received forms of documents appearing to
         fulfill the

<PAGE>

                                                                              35

         applicable conditions set forth in Article 3. Each Lender that is to
         make a B Advance as part of such B Borrowing shall, before 12:00 noon
         (New York City time) on the date of such B Borrowing specified in the
         notice received from the Administrative Agent pursuant to clause (A) of
         the preceding sentence or any later time when such Lender shall have
         received notice from the Administrative Agent pursuant to clause (C) of
         the preceding sentence, make available for the account of its
         Applicable Lending Office to the Administrative Agent at its address
         referred to in Section 8.02 such Lender's portion of such B Borrowing,
         in same day funds. Upon fulfillment of the applicable conditions set
         forth in Article 3 and after receipt by the Administrative Agent of
         such funds, the Administrative Agent will make such funds available to
         the Borrower at the Administrative Agent's aforesaid address. Promptly
         after each B Borrowing the Administrative Agent will notify each Lender
         of the amount of the B Borrowing, the consequent B Reduction and the
         dates upon which such B Reduction commenced and will terminate.

                  (b) Within the limits and on the conditions set forth in this
Section 2.19, the Borrower may from time to time borrow under this Section 2.19,
repay or prepay pursuant to subsection (c) below, and reborrow under this
Section 2.19.

                  (c) The Borrower shall repay to the Administrative Agent for
the account of each Lender which has made a B Advance, or each other holder of a
Note, on the maturity date of each B Advance (such maturity date being that
specified by the Borrower for repayment in the related Notice of B Borrowing and
provided in the Note, if any, evidencing such B Advance), the then unpaid
principal amount of such B Advance. The Borrower shall have no right to prepay
any B Advance unless, and then only on the terms, specified by the Borrower for
such B Advance in the related Notice of B Borrowing delivered pursuant to
Section 2.19(a)(i) and set forth in the Note, if any, evidencing such B Advance
or unless the holder of such B Advance otherwise consents in writing to such
prepayment.

                  (d) The Borrower shall pay interest on the unpaid principal
amount of each B Advance from the date of such B Advance to the date the
principal amount of such B Advance is repaid in full at the rate of interest for
such B Advance specified by the Lender making such B Advance in its notice
delivered pursuant to subsection (a)(ii) above on the interest date or dates
specified by the Borrower for such B Advance in the related Notice of B
Borrowing and set forth in the Note, if any, evidencing such B Advance, subject
to Section 2.06(b).

                  (e) Each time that the Borrower gives a Notice of B Borrowing,
the Borrower shall pay to the Administrative Agent for its own account such fee
as may be agreed between the Borrower and the Administrative Agent from time to
time, whether or not any B Borrowing is in fact made.

                  (f) Following the making of each B Borrowing, the Borrower
agrees that it will be in compliance with the limitations set forth in clause
(y) of the proviso to the first sentence of Section 2.19(a).

                                                                              36

                  (g) The failure of any Lender to make the B Advance to be made
by it as part of any B Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its B Advance on the date of such B
Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make the B Advance to be made by such other Lender on the date of any
B Borrowing. If any Designated Bidder fails to make the B Advance to be made by
it as part of any B Borrowing, such Designated Bidder shall not thereafter have
the right to offer to make any B Advance without the prior written consent of
the Borrower and the Administrative Agent.

                  SECTION 2.20. Increase of Commitments. (a) At any time after
the Effective Date, provided that no Event of Default shall have occurred and be
continuing, the Borrower may request an increase of the aggregate Commitments by
notice to the Administrative Agent in writing of the amount (the "OFFERED
INCREASE AMOUNT") of such proposed increase (such notice, a "COMMITMENT INCREASE
NOTICE"). Any such Commitment Increase Notice must offer each Lender the
opportunity to subscribe for its pro rata share of the increased Commitments. If
any portion of the increased Commitments is not subscribed for by the Lenders,
the Borrower may, in its sole discretion, but with the consent of the
Administrative Agent as to any Person that is not at such time a Lender (which
consent shall not be unreasonably withheld), offer to any existing Lender or to
one or more additional banks or financial institutions the opportunity to
participate in all or a portion of such unsubscribed portion of the increased
Commitments pursuant to paragraph (b) or (c) below, as applicable.

                  (b) Any additional bank or financial institution that the
Borrower selects to offer participation in the increased Commitments, and that
elects to become a party to this Agreement and obtain a Commitment, shall
execute a New Lender Agreement with the Borrower and the Administrative Agent,
substantially in the form of Exhibit E (a "NEW LENDER AGREEMENT"), whereupon
such bank or financial institution (a "NEW LENDER") shall become a Lender for
all purposes and to the same extent as if originally a party hereto and shall be
bound by and entitled to the benefits of this Agreement, and the signature pages
and Schedule III hereof shall be deemed to be amended to add the name and
Commitment of such New Lender, provided that the Commitment of any such New
Lender shall be in an amount not less than $10,000,000.

                  (c) Any Lender that accepts an offer to it by the Borrower to
increase its Commitment pursuant to this Section 2.20 shall, in each case,
execute a Commitment Increase Agreement with the Borrower and the Administrative
Agent, substantially in the form of Exhibit F (a "COMMITMENT INCREASE
AGREEMENT"), whereupon such Lender shall be bound by and entitled to the
benefits of this Agreement with respect to the full amount of its Commitment as
so increased, and Schedule III hereof shall be deemed to be amended to so
increase the Commitment of such Lender.

                  (d) The effectiveness of any New Lender Agreement or
Commitment Increase Agreement shall be contingent upon receipt by the
Administrative Agent of such corporate resolutions of the Borrower and legal
opinions of counsel to the Borrower as the Administrative Agent shall reasonably
request with respect thereto, in each case, in form and substance satisfactory
to the Administrative Agent.

                                                                              37

                  (e) If any bank or financial institution becomes a New Lender
pursuant to Section 2.20(b) or any Lender's Commitment is increased pursuant to
Section 2.20(c), additional A Advances made on or after the effectiveness
thereof (the "RE-ALLOCATION DATE") shall be made pro rata based on the
Commitment Percentages in effect on and after such Re-Allocation Date (except to
the extent that any such pro rata borrowings would result in any Lender making
an aggregate principal amount of A Advances in excess of its Commitment, in
which case such excess amount will be allocated to, and made by, such New Lender
and/or Lenders with such increased Commitments to the extent of, and pro rata
based on, their respective Commitments), and continuations of Eurodollar Rate
Advances outstanding on such Re-Allocation Date shall be effected by repayment
of such Eurodollar Rate Advances on the last day of the Interest Period
applicable thereto and the making of new Eurodollar Rate Advances pro rata based
on such new Commitment Percentages. In the event that on any such Re-Allocation
Date there is an unpaid principal amount of Base Rate Advances, the Borrower
shall make prepayments thereof and borrowings of Base Rate Advances so that,
after giving effect thereto, the Base Rate Advances outstanding are held pro
rata based on such new Commitment Percentages. In the event that on any such
Re-Allocation Date there is an unpaid principal amount of Eurodollar Rate
Advances, such Eurodollar Rate Advances shall remain outstanding with the
respective holders thereof until the expiration of their respective Interest
Periods (unless the applicable Borrower elects to prepay any thereof in
accordance with the applicable provisions of this Agreement), and interest on
and repayments of such Eurodollar Rate Advances will be paid thereon to the
respective Lenders holding such Eurodollar Rate Advances pro rata based on the
respective principal amounts thereof outstanding.

                  (f) Notwithstanding anything to the contrary in this Section
2.20, (i) no increase pursuant to this Section 2.20 shall be effective without
the consent of the Required Lenders, (ii) no Lender shall have any obligation to
increase its Commitment unless it agrees to do so in its sole discretion and
(iii) the aggregate amount by which the Commitments hereunder are increased
pursuant to this Section 2.20 shall not exceed $120,000,000.

                  (g) The Borrower shall execute and deliver a Note to each new
bank or other financial institution becoming a Lender that requests one.

                  SECTION 2.21. Extension of Stated Termination Date. (a) Not
earlier than 65 days prior to and not later than 45 days prior to the Stated
Termination Date then in effect, provided that no Event of Default shall have
occurred and be continuing, the Borrower may request an extension of such Stated
Termination Date by submitting to the Administrative Agent an Extension Request
containing the information in respect of such extension specified in Exhibit G,
which the Administrative Agent shall promptly furnish to each Lender. Each
Lender shall, by the later of (i) the date 30 days after its receipt from the
Administrative Agent of the applicable Extension Request and (ii) the date 30
days prior to the Stated Termination Date, notify the Borrower and the
Administrative Agent of its election to extend or not extend the Stated
Termination Date as requested in such Extension Request. If the Required Lenders
shall approve in writing the extension of the Stated Termination Date requested
in such Extension Request, and unless the

<PAGE>

                                                                              38

Borrower shall elect to give notice for a Term A Advance pursuant to Section
2.01(b), the Stated Termination Date shall automatically and without any further
action by any Person be extended for an additional 364 days provided that the
Commitment of any Lender that does not consent in writing within the period
specified above (an "OBJECTING LENDER") shall, unless earlier terminated in
accordance with this Agreement, expire on the Stated Termination Date in effect
on the date of such Extension Request (such Stated Termination Date, if any,
referred to as the "COMMITMENT EXPIRATION DATE" with respect to such Objecting
Lender). If, within the period specified above, the Required Lenders shall not
approve in writing the extension of the Stated Termination Date requested in an
Extension Request, the Stated Termination Date shall not be extended pursuant to
such Extension Request. The Administrative Agent shall promptly notify (y) the
Lenders and the Borrower of any extension of the Stated Termination Date
pursuant to this Section 2.21 and (z) the Borrower of any Lender that becomes an
Objecting Lender.

                  (b) A Advances owing to any Objecting Lender on the Commitment
Expiration Date, together with accrued interest thereon, any amounts payable
pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15 and 8.04(b) and any accrued
and unpaid facility fee or utilization fee or other amounts payable with respect
to such Lender shall be repaid in full on or before such Commitment Expiration
Date.

                  (c) The Borrower shall have the right, so long as no Event of
Default has occurred and is then continuing, upon giving notice to the
Administrative Agent and the Objecting Lenders in accordance with Section 2.10,
to prepay in full the A Advances of the Objecting Lenders, together with accrued
interest thereon, any amounts payable pursuant to Sections 2.06, 2.07, 2.11,
2.12, 2.15 and 8.04(b) and any accrued and unpaid facility fee or utilization
fee or other amounts payable to the Objecting Lenders hereunder and, upon giving
not less than three Business Days' notice to the Objecting Lenders and the
Administrative Agent, to cancel the whole or part of the Commitments of the
Objecting Lenders.

                  (d) Notwithstanding the foregoing, if any Lender becomes an
Objecting Lender, the Borrower may, at its own expense and in the sole
discretion and prior to the then Stated Termination Date, require such Lender
(and each related Designated Bidder (as defined herein or in the Long-Term
Revolving Credit Agreement or the Canadian Credit Agreement, as the case may
be)) to transfer or assign, in whole or in part, without recourse (in accordance
with Section 8.07), all or part of its interests, rights and obligations under
this Agreement and, if the Borrower shall so determine in its sole discretion,
the Long-Term Revolving Credit Agreement and/or the Canadian Credit Agreement,
as the Borrower may determine in its sole discretion and specify by notice to
such Lender, to an Eligible Assignee (provided that the Borrower, with the full
cooperation of such Lender, can identify an Eligible Assignee that is ready,
willing and able to be an assignee with respect thereto) which shall assume such
assigned obligations (which assignee may be another Lender, if such assignee
Lender accepts such assignment); provided that (A) the assignee or the Borrower,
as the case may be, shall have paid to such Lender in immediately available
funds the principal of and interest accrued to the date of such payment on the
Advances made by it hereunder and all other

<PAGE>

                                                                              39

amounts owed to it hereunder, including any amounts owing pursuant to Section
8.04(b), and, if the Borrower shall have so determined as specified above, the
"Advances" made by it under, and as defined in, the Long-Term Revolving Credit
Agreement and/or the Canadian Credit Agreement, as the case may be, and all
other amounts owed to it thereunder, including any amounts owing pursuant to the
provision of the Long-Term Revolving Credit Agreement and/or the Canadian Credit
Agreement, as the case may be, comparable to Section 8.04 hereof) and any
amounts that would be owing under such Section (or comparable provision) if such
Advances and "Advances" (as so defined) were prepaid on the date of such
assignment, and (B) such assignment does not conflict with any law, rule or
regulation or order of any governmental authority. Any assignee that becomes a
Lender as a result of such an assignment made pursuant to this paragraph (d)
shall be deemed to have consented to the applicable Extension Request and,
therefore, shall not be an Objecting Lender.

                  SECTION 2.22. Replacement of Lenders. If any Lender requests
compensation under Sections 2.07, 2.11 or 2.12 or if the Borrower is required to
pay any additional amount to any Lender or any taxing authority or other
authority for the account of any Lender pursuant to Section 2.15, or if any
Lender suspends the right of the Borrower to elect Eurodollar Rate Advances from
such Lender pursuant to Section 2.13, or if any Lender defaults in its
obligation to fund Advances hereunder, then the Borrower may, at its sole
expense and effort, upon notice to such Lender and the Administrative Agent,
require such Lender to assign and delegate, without recourse (in accordance with
and subject to the restrictions contained in Section 8.07), all its interests,
rights and obligations under this Agreement (other than any outstanding B
Advances held by it) and, if the Borrower shall so determine in its sole
discretion, the Long-Term Revolving Credit Agreement and/or the Canadian Credit
Agreement, as the Borrower may determine in its sole discretion and specify by
notice to such Lender (other than "B Advances" under, and as defined in, the
Long-Term Revolving Credit Agreement and/or the Canadian Credit Agreement, as
the case may be) to an assignee that shall assume such obligations (which
assignee may be another Lender, if a Lender accepts such assignment); provided
that (i) the Borrower shall have received the prior written consent of the
Administrative Agent, which consent shall not unreasonably be withheld, (ii)
such Lender shall have received payment of an amount equal to the outstanding
principal of its Advances (other than B Advances) hereunder and, if the Borrower
shall have so determined as specified above, its "Advances" (other than "B
Advances") (each under and as defined in the Long-Term Revolving Credit
Agreement and/or the Canadian Credit Agreement, as the case may be), and all
accrued interest thereon, accrued fees, accrued costs in connection with
compensation under Sections 2.07, 2.11 or 2.12 or payments required to be made
pursuant to Section 2.15, if any, and all other amounts (other than B Advances)
payable to it hereunder and, if the Borrower shall have so determined as
specified above, under the Long-Term Revolving Credit Agreement and/or the
Canadian Credit Agreement, as the case may be, from the assignee (to the extent
of such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts) and (iii) in the case of any such assignment
resulting from a claim for compensation under Sections 2.07, 2.11 or 2.12 or
payments required to be made pursuant to Section 2.15, such assignment will
result in a reduction in such compensation or payments. A Lender shall not be
required to make any such assignment and delegation if, prior thereto, as a
result

of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

                  (b) no event has occurred and is continuing, or would result
         from such A Borrowing, which constitutes an Event of Default or would

                                   ARTICLE IV

                         Representations and Warranties

                  SECTION 4.01. Representations and Warranties of the Borrower.
The Borrower represents and warrants as follows:

                  (a) The Borrower is a Business Entity duly formed, validly
         existing and in good standing under the laws of the State of Delaware.
         Each Material Subsidiary is duly organized, validly existing and in
         good standing in the jurisdiction of its formation. The Borrower and
         each Material Subsidiary possess all applicable Business Entity powers
         and all other authorizations and licenses necessary to engage in its
         business and operations as now conducted, the failure to obtain or
         maintain which would have a Material Adverse Effect. Each Subsidiary
         which is, on and as of the Effective Date, a Material Subsidiary is
         listed on Schedule I hereto.

                  (b) The execution, delivery and performance by the Borrower of
         this Agreement and the Notes, if any, are within the Borrower's
         applicable Business Entity powers, have been duly authorized by all
         necessary applicable Business Entity action, and do not contravene (i)
         the Borrower's organizational documents or (ii) law or any contractual
         restriction binding on or affecting the Borrower.

                  (c) No authorization or approval or other action by, and no
         notice to or filing with, any governmental authority or regulatory body
         is required for the due execution, delivery and performance by the
         Borrower of this Agreement or the Notes, if any, which has not been
         duly made or obtained, except those (i) required

<PAGE>

                                                                              43

         in the ordinary course to comply with ongoing covenant obligations of
         the Borrower hereunder the performance of which is not yet due and (ii)
         that will, in the ordinary course of business in accordance with this
         Agreement, be duly made or obtained on or prior to the time or times
         the performance of such obligations shall be due.

                  (d) This Agreement constitutes, and the Notes (if and when
         delivered hereunder) shall constitute, legal, valid and binding
         obligations of the Borrower enforceable against the Borrower in
         accordance with their respective terms, except as may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or other
         similar laws affecting creditors rights generally or by general
         principles of equity.

                  (e) The consolidated balance sheet of the Borrower and its
         consolidated Subsidiaries as at December 31, 2002 and the related
         consolidated statements of income and cash flow for the fiscal year
         then ended, reported on by PricewaterhouseCoopers LLC, independent
         public accountants, and the consolidated balance sheet of the Borrower
         and its consolidated subsidiaries as at September 30, 2003 and the
         related consolidated statements of income and cash flow for the
         nine-month period then ended, certified by the chief financial officer
         of the Borrower, copies of each of which have been furnished to the
         Administrative Agent and the Initial Lenders, fairly present the
         consolidated financial condition of the Borrower and such Subsidiaries
         as at December 31, 2002, and September 30, 2003, respectively, and the
         consolidated results of their operations for such fiscal periods,
         subject in the case of the September 30, 2003 statements to normal
         year-end adjustments, all in accordance with generally accepted
         accounting principles consistently applied (except as disclosed
         therein). From September 30, 2003 to and including the Effective Date
         there has been no material adverse change in such condition or results
         of operations.

                  (f) As at the Effective Date, there is no action, suit or
         proceeding pending, or to the knowledge of the Borrower threatened,
         against or involving the Borrower or any Material Subsidiary in any
         court, or before any arbitrator of any kind, or before or by any
         governmental body, which in the reasonable judgment of the Borrower
         (taking into account the exhaustion of all appeals) would have a
         material adverse effect on the consolidated financial condition of the
         Borrower and its consolidated Subsidiaries taken as a whole, or which
         purports to affect the legality, validity, binding effect or
         enforceability of this Agreement or the Notes, if any.

                  (g) The Borrower and each consolidated Subsidiary have duly
         filed all tax returns required to be filed, and duly paid and
         discharged all taxes, assessments and governmental charges upon it or
         against its properties now due and payable, the failure to file or pay
         which, as applicable, would have a Material Adverse Effect, unless and
         to the extent only that the same are being contested in good faith and
         by appropriate proceedings by the Borrower or the appropriate
         Subsidiary.

                  (h) Except to the extent permitted pursuant to Section
         5.02(e), neither the Borrower nor any Material Subsidiary is subject to
         any contractual restrictions which limit the amount of dividends
         payable by any Subsidiary.

                  (i) No Termination Event has occurred or is reasonably
         expected to occur with respect to any Plan which, with the giving of
         notice or lapse of time, or both, would constitute an Event of Default
         under Section 6.01(g).

                  (j) Neither the Borrower nor any ERISA Affiliate has incurred,
         or is reasonably expected to incur, any Withdrawal Liability to any
         Multiemployer Plan that, when aggregated with all other amounts
         required to be paid to Multiemployer Plans in connection with
         Withdrawal Liability (as of the date of determination), exceeds 5% of
         the Consolidated Tangible Net Worth of the Borrower.

                  (k) Neither the Borrower nor any ERISA Affiliate has received
         any notification that any Multiemployer Plan is in reorganization or
         has been terminated, within the meaning of Title IV of ERISA, and no
         Multiemployer Plan is reasonably expected to be in reorganization or to
         be terminated within the meaning of Title IV of ERISA the effect of
         which reorganization or termination would be the occurrence of an Event
         of Default under Section 6.01(i).

                  (l) The Borrower is not an "investment company" or a "company"
         controlled by an "investment company" within the meaning of the
         Investment Company Act of 1940, as amended.

                  (m) The Borrower is not a "holding company" or a "subsidiary
         company" of a "holding company", or an "affiliate" of a "holding
         company" or of a "subsidiary company" of a "holding company", or a
         "public utility" within the meaning of the Public Utility Holding
         Company Act of 1935, as amended.

                  (n) The proceeds of the Advances will not be used in any way
         which would violate the provisions of Regulation U or X of the Board of
         Governors of the Federal Reserve System.

                  All representations and warranties made by the Borrower herein
or made in any certificate delivered pursuant hereto shall survive the making of
the Advances and the execution and delivery to the Lenders of this Agreement and
the Notes, if any.

                            Covenants of the Borrower

                  SECTION 5.01. Affirmative Covenants. So long as any Advance,
Note or other amount payable by the Borrower hereunder shall remain unpaid or
any Lender shall have any Commitment hereunder, the Borrower will, unless the
Majority Lenders shall otherwise consent in writing:

<PAGE>

                                                                              45

                  (a) PRESERVATION OF EXISTENCE, ETC. Preserve and maintain, and
         cause each Material Subsidiary to preserve and maintain, its existence,
         rights (organizational and statutory) and material franchises, except
         as otherwise contemplated or permitted by Section 5.02(c) or 5.02(d);
         provided, that any Material Subsidiary may change its form of
         organization to a partnership or other form of Business Entity.

                  (b) COMPLIANCE WITH LAWS, ETC. Comply, and cause each
         Subsidiary to comply, in all material respects, with all applicable
         laws, rules, regulations and orders (including all environmental laws
         and laws requiring payment of all taxes, assessments and governmental
         charges imposed upon it or upon its property except to the extent
         contested in good faith by appropriate proceedings) the failure to
         comply with which would have a Material Adverse Effect.

                  (c) VISITATION RIGHTS. At such reasonable times and intervals
         as the Administrative Agent or any of the Lenders (other than
         Designated Bidders) may desire, permit the Administrative Agent or any
         of the Lenders (other than Designated Bidders) to visit the Borrower
         and to discuss the affairs, finances, accounts and mineral reserve
         performance of the Borrower and any of its Subsidiaries with officers
         of the Borrower and independent certified public accountants of the
         Borrower and any of its Subsidiaries, provided that if an Event of
         Default, or an event which with the giving of notice or the passage of
         time, or both, would become an Event of Default, has occurred and is
         continuing, the Administrative Agent or any Lender may, in addition to
         the other provisions of this subsection (c) and at such reasonable
         times and intervals as the Administrative Agent or any of the Lenders
         may desire, visit and inspect, under guidance of officers of the
         Borrower, any properties significant to the consolidated operations of
         the Borrower and its Subsidiaries, and to examine the books and records
         of account (other than with respect to any mineral reserve information
         that the Borrower determines to be confidential, except, during the
         continuation of an Event of Default, if such Lenders shall have entered
         into a confidentiality agreement with respect to such information
         satisfactory in form and substance to the Borrower) of the Borrower and
         any of its Subsidiaries and to discuss the affairs, finances and
         accounts of any of the Borrower's Subsidiaries with any of the officers
         of such Subsidiary.

                  (d) BOOKS AND RECORDS. Keep, and cause each of its
         Subsidiaries to keep, proper books of record and account, in which full
         and correct entries shall be made of all financial transactions and the
         assets and business of the Borrower and each Subsidiary in accordance
         with generally accepted accounting principles either (i) applied
         consistently with those referred to in Section 1.03 or (ii) applied in
         a changed manner that does not, under generally accepted accounting
         principles or public reporting requirements applicable to the Borrower,
         either require disclosure in the consolidated financial statements of
         the Borrower and its consolidated Subsidiaries or require the consent
         of the accountants which (as required by Section 5.03(b)) report on
         such financial statements for the fiscal year in which such change
         shall have occurred, or (iii) applied in a changed manner

<PAGE>

                                                                              46

         not covered by clause (ii) above provided such change shall have been
         disclosed to the Administrative Agent and shall have been consented to
         by the accountants which (as required by Section 5.03(b)) report on the
         consolidated financial statements of the Borrower and its consolidated
         Subsidiaries for the fiscal year in which such change shall have
         occurred, provided that if, notwithstanding the provisions of Section
         1.03, any change referred to in clause (ii) or (iii) above would result
         in a covenant contained in Section 5.01 or 5.02 being calculated or
         construed in a materially different manner or with materially different
         results than if such covenant were calculated or construed in
         accordance with the provisions of Section 1.03, the Administrative
         Agent, the Lenders and the Borrower agree, upon request by the Borrower
         to the Administrative Agent or by the Administrative Agent to the
         Borrower, to amend the covenants contained in Section 5.01 and 5.02 so
         that the relative protection afforded thereby to the Lenders and the
         relative flexibility afforded thereby to the Borrower will in substance
         be retained after such amendment, provided, however, that until such
         amendment becomes effective hereunder, the covenants as set forth
         herein shall remain in full force and effect and those definitions and
         accounting principles applicable to the Borrower and its consolidated
         Subsidiaries which do meet the standards set forth in Section 1.03
         shall be applied to determine whether or not the Borrower is in
         compliance with such covenants.

                  existing under the laws of the United States and expressly
                  assumes the obligations of the Borrower hereunder and under
                  the Notes, (B) if any such Subsidiary merges, amalgamates or
                  consolidates with (or liquidates into) any other Subsidiary of
                  the Borrower, one or more Business Entities that are
                  Subsidiaries of the Borrower are the surviving or successor
                  Business Entity(ies) and, if any such Subsidiary is not

                  lapse of time or the giving of notice, or both, would
                  constitute an Event of Default, shall have occurred and be
                  continuing, and

                           (ii) the Borrower or any Material Subsidiary may
                  merge, amalgamate or consolidate with any other Business
                  Entity (that is, in addition to the Borrower or any other
                  Subsidiary), provided that (A) if the Borrower merges,
                  amalgamates or consolidates with any such other Business
                  Entity(ies), the survivor or successor Business Entity is the
                  Borrower, (B) if any Material Subsidiary merges, amalgamates
                  or consolidates with any such other Business Entity, each

                  giving of notice, or both, would constitute an Event of
                  Default, shall have occurred and be continuing.

         sale, pledge or disposal of Margin Stock, or utilization of the
         proceeds thereof would result in a breach of any covenant contained
         therein or otherwise give rise to a default or event of default
         thereunder and/or acceleration of the maturity of the Debt extended
         pursuant thereto and as a result of such terms or of such sale, pledge,
         disposal, utilization, breach, default, event of default or
         acceleration, or the provisions hereof relating thereto, this Agreement
         or any Advance hereunder would otherwise be subject to the margin
         requirements or any other restriction under Regulation U issued by the

         the greater of (i) $100,000,000 and (ii) 3% of Consolidated Tangible

         given to the Borrower by the Lender, (i) such Termination Event shall
         still exist and (ii) the sum (determined as of the date of occurrence

         a Plan with respect to which a Termination Event described in clause
         (ii) of the definition of Termination Event shall have occurred and
         then exist, the liability related thereto), in each case in respect of
         which the Borrower or any ERISA Affiliate has liability, is equal to or
         greater than $50,000,000; or

                  (h) The Borrower or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that it has incurred
         Withdrawal Liability to such Multiemployer Plan in an amount which,

         Multiemployer Plans in connection with Withdrawal Liabilities
         (determined as of the date of such notification), exceeds $50,000,000;
         or

         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or is being terminated, within the meaning of
         Title IV of ERISA, if as a result of such reorganization or termination
         the aggregate annual contributions of the Borrower and its ERISA
         Affiliates to all Multiemployer Plans which are then in reorganization
         or being terminated have been or will be increased over the amounts
         contributed to such Multiemployer Plans for the respective plan years
         which include the Original Effective Date by an amount exceeding
         $50,000,000; or

                  (j) Upon completion of, and pursuant to, a transaction, or a
         series of transactions (which may include prior acquisitions of capital
         stock of the Borrower in the open market or otherwise), involving a
         tender offer (i) a "person" (within the meaning of Section 13(d) of the
         Securities Exchange Act of 1934) other than the Borrower, a Subsidiary
         of the Borrower or any employee benefit plan maintained for employees
         of the Borrower and/or any of its Subsidiaries or the trustee therefor,
         shall have acquired direct or indirect ownership of and paid for in

         of the directors of the Borrower consists of individuals who (a) were
         not directors before the completion of such tender offer and (b) were

         not appointed, elected or nominated by the Board of Directors in office
         prior to the completion of such tender offer (other than any such
         appointment, election or nomination required or agreed to in connection
         with, or as a result of, the completion of such tender offer); or

                  (k) Any "Event of Default" as defined in the Long-Term
         Revolving Credit Agreement or the Canadian Credit Agreement shall occur
         and be continuing;

then, and in any such event, the Administrative Agent shall at the request, or
may with the consent, of the Majority Lenders, by notice to the Borrower, (i)
declare the obligation of each Lender to make Advances to be terminated,
whereupon the same shall forthwith terminate, and (ii) declare the Advances, all
interest thereon and all other amounts payable under this Agreement to be
forthwith due and payable, whereupon the Advances, all such interest and all
such amounts shall become and be forthwith due and payable, without presentment,
demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Borrower; provided, however, that if an Event of Default under
subsection (e) of this Section 6.01 (except under clause (i)(A) thereof) shall
occur, (A) the obligation of each Lender to make Advances shall automatically be
terminated and (B) the Advances, all interest thereon and all other amounts
payable under this Agreement shall automatically become and be forthwith due and
payable, without presentment, demand, protest or any notice of any kind, all of
which are hereby expressly waived by the Borrower.

                                  ARTICLE VII

                            The Administrative Agent

                  SECTION 7.01. Authorization and Action. Each Lender hereby
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement as are delegated to
the Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including enforcement of this Agreement or collection of the
Notes), the Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement. Nothing in this Agreement shall impose upon any
Co-Syndication Agent or Co-Documentation Agent, in its capacity as such, any
duty or liability whatsoever.

                  SECTION 7.02. Administrative Agent's Reliance, Etc.. Neither
the Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection

<PAGE>

                                                                              57

with this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent: (i) may treat the payee of any Note as the holder thereof
until the Administrative Agent receives and accepts an Assignment and Acceptance
entered into by the Lender which is the payee of such Note, as assignor, and an
Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult
with legal counsel (including counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations (whether written or oral) made in or
in connection with this Agreement; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement on the part of the Borrower or to inspect the
property (including the books and records) of the Borrower; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy, cable or telex) believed by it to be genuine and signed or sent by the
proper party or parties.

                  SECTION 7.03. JPMorgan and Affiliates. With respect to its
Commitments, the Advances made by it and the Notes issued to it, JPMorgan shall
have the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Administrative Agent; and the term
"Lender" or "Lenders" shall, unless otherwise expressly indicated, include
JPMorgan in its individual capacity. JPMorgan and its affiliates may accept
deposits from, lend money to, act as trustee under indentures of, and generally
engage in any kind of business with, the Borrower, any of its Subsidiaries and
any Person who may do business with or own securities of the Borrower or any
Subsidiary, all as if JPMorgan were not the Administrative Agent and without any
duty to account therefor to the other Lenders.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon the Administrative Agent or
any other Lender and based on the financial statements referred to in Section
4.01 and such other documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Each Lender
also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

                  SECTION 7.05. Indemnification. THE LENDERS (OTHER THAN THE
DESIGNATED BIDDERS) AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT (TO THE EXTENT
NOT REIMBURSED BY THE BORROWER), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL
AMOUNTS OF THE ADVANCES THEN HELD BY EACH OF THEM (OR IF NO ADVANCES ARE AT THE
TIME

                                                                              58

OUTSTANDING OR IF ANY ADVANCES ARE HELD BY PERSONS WHICH ARE NOT LENDERS,
RATABLY ACCORDING TO THE RESPECTIVE AMOUNTS OF THEIR COMMITMENTS OR THE
RESPECTIVE AMOUNTS OF THEIR COMMITMENTS IMMEDIATELY PRIOR TO TERMINATION IF THE
COMMITMENTS HAVE BEEN TERMINATED), FROM AND AGAINST ANY AND ALL LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED
ON, INCURRED BY, OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY
RELATING TO OR ARISING OUT OF THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER
INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR
ANY ACTION TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT, OR
ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO
OR IN CONNECTION HEREWITH; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY
PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE
ADMINISTRATIVE AGENT'S GROSS NEGLIGENCE OR WILFUL MISCONDUCT. Without limitation
of the foregoing, each Lender (other than the Designated Bidders) agrees to
reimburse the Administrative Agent promptly upon demand for such Lender's
ratable share of any reasonable out-of-pocket expenses (including counsel fees)
incurred by the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings, in bankruptcy or insolvency
proceedings, or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any of the Notes or any other instrument
or document furnished pursuant hereto or in connection herewith to the extent
that the Administrative Agent acts in its capacity as Administrative Agent and
is not reimbursed for such expenses by the Borrower.

                  SECTION 7.06. Successor Administrative Agent. The
Administrative Agent may resign at any time by giving written notice thereof to
the Lenders and the Borrower and may be removed at any time with or without
cause by the Majority Lenders. Upon any such resignation or removal, the
Majority Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Majority Lenders, and shall have accepted such appointment, within 30 days after
the retiring Administrative Agent's giving of notice of resignation or the
Majority Lenders' removal of the retiring Administrative Agent, then such
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized, or authorized
to conduct a banking business, under the laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$500,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its

                                                                              59

duties and obligations under this Agreement. After any retiring Administrative
Agent's resignation or removal hereunder as Administrative Agent, the provisions
of this Article 7 shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Administrative Agent under this Agreement.

                  SECTION 7.07. Auction Administrative Agent. The Administrative
Agent shall until such time as it so notifies the Borrower and the Lenders
discharge its duties under Section 2.19 through the Auction Administrative Agent
and all references to the "Administrative Agent" or to JPMorgan relating to such
duties or made in this Article 7 shall be deemed to also refer to the Auction
Administrative Agent and any Affiliate of JPMorgan serving in such capacity. All
payments to be made to or by the Auction Administrative Agent shall be made
through the Administrative Agent.

                                  ARTICLE VIII

                                  Miscellaneous

                  SECTION 8.01. Amendments, Etc. An amendment or waiver of any
provision of this Agreement or the Notes, or a consent to any departure by the
Borrower therefrom, shall be effective against the Lenders and all holders of
the Notes if, but only if, it shall be in writing and signed by the Majority
Lenders or, where so specified, the Required Lenders (except any amendment to
give effect to increased Commitments and New Lenders, as contemplated by Section
2.20), and then such a waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no such amendment, waiver or consent shall, unless in writing and signed by all
the Lenders (other than the Designated Bidders), be effective to: (a) waive any
of the conditions specified in Article 3, (b) except as contemplated by Section
2.20, increase the Commitments of the Lenders or subject the Lenders to any
additional obligations, (c) reduce the principal of, or interest on, the
Advances or any facility fees or utilization fees hereunder, (d) except as

this Agreement, the Notes and the other documents to be delivered hereunder and
thereunder.

                  (b) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance is made by the Borrower to or for the account of a
Lender on any day other than the last day of the Interest Period for such
Advance, as a result of a prepayment pursuant to Section 2.10 or a Conversion
pursuant to Section 2.08(d) or Section 2.09 or due to acceleration of the
maturity of the Advances pursuant to Section 6.01 or due to any other reason

DAMAGES, LIABILITIES AND EXPENSES (INCLUDING FEES AND DISBURSEMENTS OF COUNSEL)
WHICH MAY BE INCURRED BY OR ASSERTED AGAINST ANY INDEMNIFIED PARTY IN CONNECTION
WITH OR ARISING OUT OF ANY INVESTIGATION, LITIGATION, OR PROCEEDING (WHETHER OR
NOT SUCH INDEMNIFIED PARTY IS PARTY THERETO) RELATED TO ANY ACQUISITION OR
PROPOSED ACQUISITION BY THE BORROWER, OR BY ANY SUBSIDIARY OF THE BORROWER, OF
ALL OR ANY PORTION OF THE EQUITY INTERESTS IN, OR SUBSTANTIALLY ALL THE ASSETS
OF, ANY PERSON OR ANY USE OR

<PAGE>

                                                                              62

PROPOSED USE OF THE ADVANCES BY THE BORROWER (EXCLUDING ANY CLAIMS, DAMAGES,
LIABILITIES OR EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH INDEMNIFIED PARTY OR ANY OF ITS RELATED PERSONS, OR BY REASON
OF ANY USE OR DISCLOSURE BY SUCH INDEMNIFIED PARTY OR ANY OF ITS RELATED PERSONS
OF INFORMATION RELATING TO ANY SUCH ACQUISITION OR PROPOSED ACQUISITION OR ANY
SUCH USE OR PROPOSED USE OF THE ADVANCES).

                  SECTION 8.05. Right of Set-off. Upon the declaration of the
Advances as due and payable pursuant to the provisions of Section 6.01, each
Lender is hereby authorized at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement and any Note held by such Lender,
irrespective of whether or not such Lender shall have made any demand under this
Agreement or such Note and although such obligations may be unmatured. Each
Lender agrees promptly to notify the Borrower after any such set-off and
application made by such Lender, provided that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of
each Lender under this Section 8.05 are in addition to other rights and remedies
(including other rights of set-off) which such Lender may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective in accordance with the provisions of Section 3.01, and thereafter
shall be binding upon and inure to the benefit of the Borrower, the
Administrative Agent, the Arranger and each Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of all of the Lenders.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
(other than a Designated Bidder) may assign to one or more banks or other
entities all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment, the A Advances owing to it and
the Note or Notes held by it); provided, however, that each such assignment
shall be to an Eligible Assignee, and the parties to each such assignment shall
execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any Note
or Notes subject to such assignment and, except in the case of an assignment to
a Lender Affiliate, a processing and recordation fee of $3,000, and shall send
to the Borrower an executed counterpart of such Assignment and Acceptance, and
provided further, however, that (i) the sum of (x) the amount of the Commitment
of the assigning Lender being assigned to the assignee pursuant to each such
assignment (determined as of the date of the Assignment) plus (y) the amount of
the "Commitment" of the assigning Lender under the Long-Term Revolving Credit
Agreement and/or the Canadian Credit Agreement contemporaneously assigned by
such assigning Lender to such assignee as contemplated by clause (iii) of this
sentence must be equal to or greater than

<PAGE>

                                                                              63

$25,000,000, or if less, the entire amount of such assigning Lender's
"Commitment" (unless the Borrower and the Administrative Agent shall otherwise
consent, which consent may be withheld for any reason) and must be an integral
multiple of $1,000,000, (ii) any assignment to a Lender Affiliate will not
relieve the assigning Lender of its obligation to make Advances hereunder timely
in accordance with the terms hereof in the event such Lender Affiliate shall
fail to do so and (iii) except in the case of an assignment to a Lender
Affiliate or as required by the Borrower pursuant Section 2.21(d) or 2.22, each
such assignment shall be of a constant, and not a varying, percentage of all
such Lender's rights and obligations under this Agreement (other than any right
to make B Advances, any B Advances or any Notes) and the same constant
percentage of all such Lender's rights and obligations, if any, under the
Long-Term Revolving Credit Agreement and the Canadian Credit Agreement unless
the Long-Term Revolving Credit Agreement or the Canadian Agreement, as the case
may be, has been terminated, shall be contemporaneously assigned by such
assigning Lender to the same assignee pursuant to Section 8.07(a) of the
Long-Term Revolving Credit Agreement and Section 9.07(a) of the Canadian Credit
Agreement. Upon the execution, delivery, acceptance and recording of each
Assignment and Acceptance by the parties thereto, from and after the effective
date specified in such Assignment and Acceptance, (x) the assignee thereunder
shall be a party hereto and, to the extent that rights and obligations hereunder
have been assigned to it pursuant to such Assignment and Acceptance, have the
rights and obligations of a Lender hereunder and (y) except as otherwise
provided in clause (ii) above, the Lender assignor thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment and Acceptance, relinquish its rights and be released from
its obligations under this Agreement (and, except in the circumstances
contemplated by clause (ii) above, in the case of an Assignment and Acceptance
covering all or the remaining portion of an assigning Lender's rights and
obligations under this Agreement, such Lender shall cease to be a party hereto,
provided, however, that such assigning Lender shall retain any claim with
respect to any fee, interest, cost, expense or indemnity which accrues, or
relates to an event that occurs, prior to the date of such assignment pursuant
to Section 2.03, 2.06, 2.07, 2.11, 2.12, 2.15 or 8.04).

                  (b) By executing and delivering an Assignment and Acceptance,
each Lender assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning

<PAGE>

                                                                              64

Lender or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms
that it is (subject to approval in writing by the Borrower and the
Administrative Agent to the extent required) an Eligible Assignee; (vi) such
assignee appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 8.02 a copy of each Assignment and Acceptance, each
Designation Agreement, each New Lender Agreement and each Commitment Increase
Agreement delivered to and accepted by it and a register for the recordation of
the names and addresses of the Lenders and, with respect to Lenders other than
Designated Bidders, the Commitment of, and principal amount of the A Advances
owing to, each Lender from time to time (the "REGISTER"). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

                  (d) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee representing that it is an Eligible
Assignee, together with any Note or Notes subject to such assignment, the
Administrative Agent shall, if such Assignment and Acceptance has been completed
and is in substantially the form of Exhibit D hereto, (i) accept such Assignment
and Acceptance, (ii) record the information contained therein in the Register
and (iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice and its receipt of an executed counterpart of
such Assignment and Acceptance, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent in exchange for any surrendered Note or
Notes a new Note to the order of such Eligible Assignee and, if the assigning
Lender has retained a Commitment hereunder, a new Note to the order of the
assigning Lender. Any such new Note or Notes shall be dated the effective date
of such Assignment and Acceptance and shall otherwise be in substantially the
form of Exhibit A hereto.

                  (e) Each Lender (other than a Designated Bidder) may designate
one or more banks or other entities to have a right to make B Advances as a
Lender pursuant to Section 2.19; provided that (i) such Lender shall have
obtained the written consent of the Administrative Agent and the Borrower, such
consent not to be unreasonably withheld, (ii) no such Lender shall be entitled
to make more than two such designations, (iii) each such Lender making one or
more of such designations shall retain the right to make B Advances as a Lender
pursuant to Section 2.19, (iv) each such designation shall be to a Designated
Bidder and (v) the parties to each such designation shall execute and deliver to
the Administrative Agent, for its acceptance and recording in the Register, a

<PAGE>

                                                                              65

Designation Agreement. Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Designation Agreement, the
designee thereunder shall be a party hereto with a right to make B Advances as a
Lender pursuant to Section 2.19 and the obligations related thereto.

                  (f) By executing and delivering a Designation Agreement, the
Lender making the designation thereunder and its designee thereunder confirm and
agree with each other and the other parties hereto as follows: (i) such Lender
makes no representation or warranty and assumes no responsibility with respect
to any statements, warranties or representations made in or in connection with
this Agreement or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other instrument or
document furnished pursuant hereto, (ii) such Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such designee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into the
Designation Agreement; (iv) such designee will, independently and without
reliance upon the Administrative Agent, such designating Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such designee confirms that it is a Designated
Bidder; (vi) such designee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto, and (vii) such
designee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

                  (g) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Administrative Agent shall, if such Designation Agreement has been completed
and is substantially in the form of Exhibit J hereto, (i) accept such
Designation Agreement, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower.

                  (h) Each Lender may sell participations to one or more banks
or other entities in or to all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment, and the Advances
owing to it and the Note or Notes held by it); provided, however, that (i) such
Lender's obligations under this Agreement (including its Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, 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, (v)
such

<PAGE>

                                                                              66

Lender shall continue to be able to agree to any modification or amendment of
this Agreement or any waiver hereunder without the consent, approval or vote of
any such participant or group of participants, other than modifications,
amendments and waivers which (A) postpone any date fixed for any payment of, or
reduce any payment of, principal of or interest on such Lender's Advances or any
facility fees or utilization fees payable under this Agreement, or (B) increase
the amount of such Lender's Commitment in a manner which would have the effect
of increasing the amount of a participant's participation, or (C) reduce the
interest rate payable under this Agreement and such Lender's Advances, or (D)
consent to the assignment or the transfer by the Borrower of any of its rights
and obligations under the Agreement, and (vi) except as contemplated by the
immediately preceding clause (v), no participant shall be deemed to be or to
have any of the rights or obligations of a "Lender" hereunder.

                  (i) Any Lender may, in connection with any assignment,
designation or participation or proposed assignment, designation or
participation pursuant to this Section 8.07, disclose to the assignee, designee
or participant or proposed assignee, designee or participant, any information
relating to the Borrower furnished to such Lender by or on behalf of the
Borrower; provided that, prior to any such disclosure, the assignee, designee or
participant or proposed assignee, designee or participant shall agree in writing
for the benefit of the Borrower to preserve the confidentiality of any
confidential information relating to the Borrower received by it from such
Lender in a manner consistent with Section 8.08.

                  (j) Anything in this Agreement to the contrary
notwithstanding, any Lender may at any time create a security interest in all or
any portion of its rights under this Agreement (including the Advances owing to
it) and the Notes, if any, issued to it hereunder in favor of any Federal
Reserve Bank in accordance with Regulation A of the Board of Governors of the
Federal Reserve System (or any successor regulation) and the applicable
operating circular of such Federal Reserve Bank.

                  SECTION 8.08. Confidentiality. (a) Each Lender and the
Administrative Agent (each, a "PARTY") agrees that it will use its best
reasonable efforts not to disclose, without the prior consent of the Borrower
(other than to its, or its Affiliates, employees, auditors, accountants, counsel
or other representatives, whether existing at the Original Effective Date or any
subsequent time), any information with respect to the Borrower which is
furnished pursuant to this Agreement, provided that any party may disclose any
such information (i) as has become generally available to the public, (ii) as
may be required or appropriate in any report, statement or testimony submitted
to any municipal, state or Federal regulatory body having or claiming to have
jurisdiction over such party or to the Board of Governors of the Federal Reserve
System or the Federal Deposit Insurance Corporation or similar organizations
(whether in the United States or elsewhere) or their successors, (iii) as may be
required or appropriate in response to any summons or subpoena or in connection
with any litigation or regulatory proceeding, (iv) in order to comply with any
law, order, regulation or ruling applicable to such party, or (v) to any
prospective assignee, designee or participant in connection with any
contemplated assignment of any rights or obligations hereunder, any designation
or any sale of any participation therein, by such party pursuant to Section
8.07, if such

<PAGE>

                                                                              67

prospective assignee, designee or participant, as the case may be, executes an
agreement with the Borrower containing provisions substantially similar to those
contained in this Section 8.08; provided, however, that the Borrower
acknowledges that the Administrative Agent has disclosed and may continue to
disclose such information as the Administrative Agent in its sole discretion
determines is appropriate to the Lenders from time to time.

                  (b) Notwithstanding anything herein to the contrary, any party
subject to confidentiality obligations hereunder (and any employee,
representative or other agent of such party) may disclose to any and all
persons, without limitation of any kind, such party's U.S. federal income tax
treatment and the U.S. federal income tax structure of the transactions
contemplated hereby relating to such party 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
nondisclosure is reasonably necessary in order to comply with applicable
securities laws.

                  SECTION 8.09. Consent to Jurisdiction. (a) The Borrower hereby
irrevocably submits to the jurisdiction of any New York State or Federal court
sitting in New York City and any appellate court from any thereof in any action
or proceeding by the Administrative Agent, the Arranger, any Lender or the
holder of any Note in respect of, but only in respect of, any claims or causes
of action arising out of or relating to this Agreement or the Notes (such claims
and causes of action, collectively, being "PERMITTED CLAIMS"), and the Borrower
hereby irrevocably agrees that all Permitted Claims may be heard and determined
in such New York State court or in such Federal court. The Borrower hereby
irrevocably waives, to the fullest extent it may effectively do so, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
aforementioned court in respect of Permitted Claims. Service of the summons and
complaint and any other process which may be served by the Administrative Agent,
the Arranger, any Lender or the holder of any Note on the Borrower in any such
action or proceeding in any aforementioned court in respect of Permitted Claims
may be made by delivering separate copies of such process to the Borrower by
courier and by certified mail (return receipt requested), fees and postage
prepaid at the Borrower's address specified pursuant to Section 8.02, to the
attention of each of the Treasurer and the Executive Vice President, Law. The
Borrower 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.

                  (b) Nothing in this Section 8.09 (i) shall affect the right of
the Arranger, the Borrower, any Lender, the holder of any Note or the
Administrative Agent to serve legal process in any other manner permitted by law
or affect any right otherwise existing of the Borrower, any Lender, the
Arranger, the holder of any Note or the Administrative Agent to bring any action
or proceeding in the courts of other jurisdictions or (ii) shall be deemed to be
a general consent to jurisdiction in any particular court or a general waiver of
any defense or a consent to jurisdiction of the courts expressly referred to in
subsection (a) above in any action or proceeding in respect of any claim or
cause of action other than Permitted Claims.

The applicable pricing level shall change on the date of any relevant change in
the rating by S&P or Moody's of any public long term senior unsecured debt
securities of the Borrower. In the case of split ratings from S&P and Moody's,
the rating to be used to determine the applicable pricing level is the higher of
the two (e.g., A-/Baa1 results in Level II pricing), provided that in the event
the split is more than one full category, the average (or the higher of two
intermediate ratings) shall be used (e.g., A-/Baa2 results in Level III pricing,
as does A-/Baa3).
