                                   The Credits

         SECTION 2.1 Commitments. Subject to the terms and conditions set forth
herein, each Lender agrees to make Revolving Loans in U.S. Dollars to Borrower
from time to time during the Availability Period in an aggregate principal
amount that will not result in (a) such Lender's Revolving Credit Exposure
exceeding such Lender's Commitment or (b) the sum of the total Revolving Credit
Exposures plus the aggregate principal amount of outstanding Competitive Loans
exceeding the total Commitments. Subject to the conditions set forth herein,
Borrower may borrow, prepay and reborrow Revolving Loans. Apache and any
Additional Borrowers shall be jointly and severally liable for all Obligations.

         SECTION 2.2 Loans and Borrowings.

         (a) Each Revolving Loan shall be made as part of a Borrowing consisting
of Revolving Loans made by the Lenders ratably in accordance with their
respective Commitments. Each Competitive Loan shall be made in accordance with
the procedures set forth in Section 2.4. The failure of any Lender to make any
Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments and Competitive Bids of the
Lenders are several and no Lender shall be responsible for any other Lender's
failure to make Loans as required.

         (b) Subject to Section 2.13, (i) each Revolving Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as Borrower may request in
accordance herewith, and (ii) each Competitive Borrowing shall be comprised
entirely of Eurodollar Loans or Fixed Rate Loans as Borrower may request in
accordance herewith. Each Lender at its option may make any Eurodollar Loan by
causing any domestic or foreign branch or Affiliate of such Lender to make such
Loan; provided that any exercise of such option shall not affect the obligation
of Borrower to repay such Loan in accordance with the terms of this Agreement.

         (c) At the commencement of each Interest Period for any Eurodollar
Revolving Borrowing, such Borrowing shall be in an aggregate amount that is an
integral multiple of $1,000,000 and not less than $5,000,000 (including any
continuation or conversion of existing Revolving Loans made in connection
therewith). At the time that each ABR Revolving Borrowing is made, such
Borrowing shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 (including any continuation or
conversion of existing Revolving Loans made in connection therewith); provided
that an ABR Revolving Borrowing may be in an aggregate amount that is equal to
the entire unused balance of the total Commitments. Each Competitive Borrowing
shall be in an aggregate amount that is an integral multiple of $1,000,000 and
not less than $5,000,000. Borrowings of more than one Type and Class may be
outstanding at the same time; provided that there shall not at any time be more
than a total of ten (10) Eurodollar Revolving Borrowings outstanding.

                                       17
<PAGE>

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

         SECTION 2.3 Requests for Revolving Borrowings. To request a Revolving
Borrowing, Borrower shall notify the Global Administrative Agent of such request
by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00
p.m., New York City time, three Business Days before the date of the proposed
Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New
York City time, on the date of the proposed Borrowing. Each such telephonic
Borrowing Request shall be irrevocable and shall be confirmed promptly by hand

Request in a form approved by the Global Administrative Agent and signed by
Borrower. Each such telephonic and written Borrowing Request shall specify the
following information in compliance with Section 2.2:

                  (i) the aggregate amount of the requested Borrowing;

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

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

                  (iv) in the case of a Eurodollar Borrowing, the initial
         Interest Period to be applicable thereto, which shall be a period
         contemplated by the definition of the term "Interest Period".

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

         SECTION 2.4 Competitive Bid Procedure.

         (a) Subject to the terms and conditions set forth herein, from time to
time during the Availability Period, Borrower may request Competitive Bids and
may (but shall not have any obligation to) accept Competitive Bids and borrow
Competitive Loans; provided that the sum of the total Revolving Credit Exposures
plus the aggregate principal amount of outstanding Competitive Loans at any time
shall not exceed the total Commitments. To request Competitive Bids, Borrower
shall notify the Global Administrative Agent of such request by telephone, in
the case of a Eurodollar Borrowing, not later than noon, New York City time,
four Business Days before the date of the proposed Borrowing and, in the case of
a Fixed Rate Borrowing, not later than 10:00 a.m., New York City time, one

may submit up to (but not more than) five (5) Competitive Bid Requests on the
same day, but a Competitive Bid Request shall not be made within five

                                       18
<PAGE>

Business Days after the date of any previous Competitive Bid Request, unless any
and all such previous Competitive Bid Requests shall have been withdrawn or all
Competitive Bids received in response thereto rejected. Each such telephonic
Competitive Bid Request shall be confirmed promptly by hand delivery or telecopy
to the Global Administrative Agent of a written Competitive Bid Request and
signed by Borrower. Each such telephonic and written Competitive Bid Request
shall specify the following information in compliance with Section 2.2:

                  (i) the aggregate amount of the requested Borrowing;

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

                  (iii) whether such Borrowing is to be a Eurodollar Borrowing
         or a Fixed Rate Borrowing; and

                  (iv) the Interest Period to be applicable to such Borrowing,
         which shall be a period contemplated by the definition of the term
         "Interest Period".

Promptly following receipt of a Competitive Bid Request in accordance with this
Section, the Global Administrative Agent shall notify the Lenders of the details
thereof by telecopy to each Lender of a Notice of Competitive Bid Quote Request
inviting the Lenders to submit Competitive Bids.

         (b) Each Lender may (but shall not have any obligation to) make one or
more Competitive Bids to Borrower in response to a Competitive Bid Request. Each
Competitive Bid by a Lender must be in a form approved by the Global
Administrative Agent and must be received by the Global Administrative Agent by
telecopy, in the case of a Eurodollar Competitive Borrowing, not later than
noon, New York City time, three Business Days before the proposed date of such
Competitive Borrowing, and in the case of a Fixed Rate Borrowing, not later than
10:00 a.m., New York City time, on the proposed date of such Competitive
Borrowing. Competitive Bids that do not conform substantially to the form
approved by the Global Administrative Agent may be rejected by the Global
Administrative Agent, and the Global Administrative Agent shall notify the
applicable Lender as promptly as practicable. Each Competitive Bid shall specify
(i) the principal amount (which shall be a minimum of $5,000,000 and an integral
multiple of $1,000,000 and which may equal the entire principal amount of the
Competitive Borrowing requested by Borrower) of the Competitive Loan or Loans
that the Lender is willing to make, (ii) the Competitive Bid Rate or Rates at
which the Lender is prepared to make such Loan or Loans (expressed as a
percentage rate per annum in the form of a decimal to no more than four decimal
places) and (iii) the Interest Period applicable to each such Loan and the last
day thereof.

         (c) The Global Administrative Agent shall promptly notify Borrower by
telecopy of a summary of the Competitive Bid Rate and the principal amount
specified in each Competitive Bid and the identity of the Lender that shall have
made such Competitive Bid.

         (d) Subject only to the provisions of this paragraph, Borrower may
accept or reject any Competitive Bid. Borrower shall notify the Global

                                       19
<PAGE>

what extent it has decided to accept or reject each Competitive Bid, in the case
of a Eurodollar Competitive Borrowing, not later than 1:00 p.m., New York City
time, three Business Days before the date of the proposed Competitive Borrowing,
and in the case of a Fixed Rate Borrowing, not later than 11:00 a.m., New York
City time, on the proposed date of the Competitive Borrowing; provided that (i)
the failure of Borrower to give such notice shall be deemed to be a rejection of
each Competitive Bid, (ii) Borrower shall not accept a Competitive Bid made at a
particular Competitive Bid Rate if Borrower rejects a Competitive Bid made at a
lower Competitive Bid Rate, (iii) the aggregate amount of the Competitive Bids
accepted by Borrower shall not exceed the aggregate amount of the requested
Competitive Borrowing specified in the related Competitive Bid Request, (iv) to
the extent necessary to comply with clause (iii) above, Borrower may accept
Competitive Bids at the same Competitive Bid Rate in part, which acceptance, in
the case of multiple Competitive Bids at such Competitive Bid Rate, shall be
made pro rata in accordance with the amount of each such Competitive Bid, and
(v) except pursuant to clause (iv) above, no Competitive Bid shall be accepted
for a Competitive Loan unless such Competitive Loan is in a minimum principal
amount of $5,000,000 and an integral multiple of $1,000,000; provided further
that if a Competitive Loan must be in an amount less than $5,000,000 because of
the provisions of clause (iv) above, such Competitive Loan may be for a minimum
of $1,000,000 or any integral multiple thereof, and in calculating the pro rata
allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner determined by Borrower.
A notice given by Borrower pursuant to this paragraph shall be irrevocable.

         (e) The Global Administrative Agent shall promptly notify each bidding
Lender by telecopy whether or not its Competitive Bid has been accepted (and, if
so, the amount and Competitive Bid Rate so accepted), and each successful bidder
will thereupon become bound, subject to the terms and conditions hereof, to make
the Competitive Loan in respect of which its Competitive Bid has been accepted.

         (f) If the Global Administrative Agent shall elect to submit a
Competitive Bid in its capacity as a Lender, it shall submit such Competitive
Bid directly to Borrower at least one quarter of an hour earlier than the time
by which the other Lenders are required to submit their Competitive Bids to the
Global Administrative Agent pursuant to paragraph (b) of this Section.

         SECTION 2.5 Funding of Borrowings.

         (a) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00
noon, New York City time, to the account of the Global Administrative Agent most
recently designated by it for such purpose by notice to the Lenders. The Global
Administrative Agent will make such Loans available to Borrower by promptly
crediting the amounts so received, in like funds, to an account of Borrower
designated by Borrower from time to time in a written notice to the Global
Administrative Agent executed by two Authorized Officers of Apache and two
Authorized Officers of any Additional Borrower.

         (b) Unless the Global Administrative Agent shall have received notice
from a Lender prior to the proposed date of any Borrowing that such Lender will
not make available to the

                                       20
<PAGE>

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

         SECTION 2.6 Extension of Maturity Date and of Commitments.

         (a) Subject to the other provisions of this Agreement and provided that
no Event of Default has occurred and is continuing, the total Commitments shall
be effective for an initial period from the Global Effective Date to the
Original Maturity Date; provided that the Maturity Date, and concomitantly the
total Commitments, may be extended for successive one year periods expiring on
the date which is one (1) year from the then scheduled Maturity Date. If
Borrower shall request in a Certificate of Extension delivered to the Global
Administrative Agent at least 45 days prior to a date which is an anniversary of
the Global Effective Date that the Maturity Date be extended for one year from
the then scheduled Maturity Date, then the Global Administrative Agent shall
promptly notify each Lender of such request and each Lender shall notify the
Global Administrative Agent, no later than 30 days prior to such anniversary of
the Global Effective Date, whether such Lender, in the exercise of its sole
discretion, will extend the Maturity Date for such one year period. Any Lender
which shall not timely notify the Global Administrative Agent whether it will
extend the Maturity Date shall be deemed to not have agreed to extend the
Maturity Date. No Lender shall have any obligation whatsoever to agree to extend
the Maturity Date. Any agreement to extend the Maturity Date by any Lender shall
be irrevocable, except as provided in Section 2.6(c).

         (b) If all Lenders notify the Global Administrative Agent pursuant to
clause (a) of this Section 2.6 of their agreement to extend the Maturity Date,
then the Global Administrative Agent shall so notify each Lender and Borrower,
and such extension shall be effective without other or further action by any
party hereto for such additional one year period.

         (c) If Lenders constituting at least the Required Lenders approve the
extension of the then scheduled Maturity Date (such Lenders agreeing to extend
the Maturity Date herein called the "Accepting Lenders") and if one or more
Lenders shall notify, or be deemed to notify, the Global Administrative Agent
pursuant to clause (a) of this Section 2.6 that they will not extend the then
scheduled Maturity Date (such Lenders herein called the "Declining Lenders"),
then (A) the Global Administrative Agent shall promptly so notify Borrower and
the Accepting Lenders, (B) the Accepting Lenders shall, upon Borrower's election
to extend the then scheduled Maturity Date in accordance with clause (i) or (ii)
below, extend the then scheduled Maturity

Date and (C) Borrower shall, pursuant to a notice delivered to the Global
Administrative Agent, the Accepting Lenders and the Declining Lenders, no later
than the tenth (10th) day following the date by which each Lender is required,
pursuant to Section 2.6(a), to approve or disapprove the requested extension of
the total Commitments, either:

                  (i) elect to extend the Maturity Date and direct the Declining
         Lenders to terminate their Commitments, which termination shall become
         effective on the date which would have been the Maturity Date except
         for the operation of this Section. On the date which would have been
         the Maturity Date except for the operation of this Section, (x)
         Borrower shall deliver a notice of the effectiveness of such
         termination to the Declining Lenders with a copy to the Global
         Administrative Agent and (y) Borrower shall pay in full in immediately
         available funds all Obligations of Borrower owing to the Declining
         Lenders, including any amounts required pursuant to Section 2.15, and
         (z) upon the occurrence of the events set forth in clauses (x) and (y),
         the Declining Lenders shall each cease to be a Lender hereunder for all
         purposes, other than for purposes of Sections 2.14 through 2.17,
         Section 2.19 and Section 10.3, and shall cease to have any obligations
         or any Commitment hereunder, other than to the Agents pursuant to
         Article IX, and the Global Administrative Agent shall promptly notify
         the Accepting Lenders and Borrower of the new Commitments; or

                  (ii) elect to extend the Maturity Date and, prior to or no
         later than the then scheduled Maturity Date, (A) to replace one or more
         of the Declining Lenders with another lender or lenders reasonably
         acceptable to the Global Administrative Agent (such lenders herein
         called the "Replacement Lenders") and (B) Borrower shall pay in full in
         immediately available funds all Obligations of Borrower owing to any
         Declining Lenders which are not being replaced, as provided in clause
         (i) above; provided that (x) any Replacement Lender shall purchase, and
         any Declining Lender shall sell, such Declining Lender's rights and
         obligations hereunder without recourse or expense to, or warranty by,
         such Declining Lender being replaced for a purchase price equal to the
         aggregate outstanding principal amount of the Obligations payable to
         such Declining Lender plus any accrued but unpaid interest on such
         Obligations and accrued but unpaid fees or other amounts owing in
         respect of such Declining Lender's Loans and Commitments hereunder, and
         (y) upon the payment of such amounts referred to in clause(x) and the
         execution of an Assignment and Acceptance by such Replacement Lender
         and such Declining Lender, such Replacement Lender shall constitute a
         Lender hereunder and such Declining Lender being so replaced shall no
         longer constitute a Lender (other than for purposes of Sections 2.14
         through 2.17, Section 2.19 and Section 10.3), and shall no longer have
         any obligations hereunder, other than to the Agents pursuant to Article
         IX; or

                  (iii) elect to revoke and cancel the extension request in such
         Certificate of Extension by giving notice of such revocation and
         cancellation to the Global Administrative Agent (which shall promptly
         notify the Lenders thereof) no later than the tenth (10th) day
         following the date by which each Lender is required, pursuant to clause
         (a) of this Section, to approve or disapprove the requested extension
         of the Maturity Date, and concomitantly the total Commitments.

<PAGE>

         If Borrower fails to timely provide the election notice referred to in
this clause(c), Borrower shall be deemed to have revoked and cancelled the
extension request in the Certificate of Extension and to have elected not to
extend the Maturity Date.

         SECTION 2.7 Interest Elections.

         (a) Each Revolving Borrowing initially shall be of the Type specified
in the applicable Borrowing Request (or an ABR Borrowing if no Type is
specified) and, in the case of a Eurodollar Revolving Borrowing, shall have an
initial Interest Period as specified in such Borrowing Request (or one month if
no Interest Period is specified). Thereafter, Borrower may elect to convert such
Borrowing to a different Type or to continue such Borrowing and, in the case of
a Eurodollar Revolving Borrowing, may elect Interest Periods therefor, all as
provided in this Section. Borrower may, subject to the requirements of Section
2.2(c), elect different options with respect to different portions of the
affected Borrowing, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing. This
Section shall not apply to Competitive Borrowings, which may not be converted or
continued.

         (b) To make an election pursuant to this Section, Borrower shall notify
the Global Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.3 if Borrower were
requesting a Revolving Borrowing of the Type resulting from such election to be
made on the effective date of such election. Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Global Administrative Agent of a written Interest
Election Request signed by Borrower.

         (c) Each telephonic and written Interest Election Request shall specify
the following information in compliance with Section 2.2:

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

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

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

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

                                       23
<PAGE>

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

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

         (e) If Borrower fails to deliver a timely Interest Election Request
with respect to a Eurodollar Revolving Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as
provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if
an Event of Default has occurred and is continuing and the Global Administrative
Agent, at the request of the Required Lenders, so notifies Borrower, then, so
long as an Event of Default is continuing, (i) no outstanding Revolving
Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii)
unless repaid and provided the Indebtedness has not been accelerated pursuant to
Section 8.3, each Eurodollar Revolving Borrowing shall be converted to an ABR
Borrowing at the end of the Interest Period applicable thereto.

         SECTION 2.8 Termination and Reduction of Commitments.

         (a) Unless previously terminated, the Commitments shall terminate on
the Maturity Date.

         (b) Borrower may at any time terminate, or from time to time reduce,
the Commitments; provided that (i) each reduction of the Commitments shall be in
an amount that is an integral multiple of $1,000,000 and not less than
$5,000,000 and (ii) Borrower shall not terminate or reduce the Commitments if,
after giving effect to any concurrent prepayment of the Loans in accordance with
Section 2.10, the sum of the Revolving Credit Exposures plus the aggregate
principal amount of outstanding Competitive Loans would exceed the total
Commitments.

         (c) Borrower shall notify the Global Administrative Agent of any
election to terminate or reduce the Commitments under paragraph (b) of this
Section at least two Business Days prior to the effective date of such
termination or reduction, specifying such election and the effective date
thereof. Promptly following receipt of any notice, the Global Administrative
Agent shall advise the Lenders of the contents thereof. Each notice delivered by
Borrower pursuant to this Section shall be irrevocable; provided that a notice
of termination of the Commitments delivered by Borrower may state that such
notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by Borrower (by notice to the Global
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. Any termination or reduction of the Commitments
shall be permanent. Each reduction of the Commitments shall be made ratably
among the Lenders in accordance with their respective Commitments.

         SECTION 2.9 Repayment of Loans; Evidence of Debt.

                                       24
<PAGE>

         (a) Borrower hereby unconditionally promises to pay (i) to the Global
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Revolving Loan on the Maturity Date or, if earlier, the date on
which the Commitment of such Lender relating to such Revolving Loan is
terminated (except for termination of the Commitment of the assigning Lender
pursuant to Section 10.4(b)), and (ii) to the Global Administrative Agent for
the account of each Lender the then unpaid principal amount of each Competitive
Loan on the last day of the Interest Period applicable to such Loan.

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

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

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

         (e) Any Lender may request that Loans made by it be evidenced by one or
more promissory notes. In such event, Borrower shall prepare, execute and
deliver to such Lender promissory notes payable to the order of such Lender (or,
if requested by such Lender, to such Lender and its registered assigns and in a
form approved by the Global Administrative Agent). Thereafter, the Loans
evidenced by such promissory notes and interest thereon shall at all times
(including after assignment pursuant to Section 10.4) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if any such promissory note is a registered note, to such payee and
its registered assigns).

         SECTION 2.10 Prepayment of Loans.

         (a) Borrower shall have the right at any time and from time to time to
prepay any Borrowing in whole or in part, subject to prior notice in accordance
with paragraph (b) of this Section; provided that Borrower shall not have the
right to prepay any Competitive Loan without the prior consent of the Lender
thereof and compensation for break funding, to the extent required by Section
2.15.

         (b) Borrower shall notify the Global Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Revolving Borrowing, not later than 1:00 p.m., New
York City time, three Business Days before the date of prepayment or (ii) in the
case of prepayment of an ABR Revolving Borrowing, not

                                       25
<PAGE>

later than 11:00 a.m., New York City time, on the date of prepayment. Each such
notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid; provided
that, if a notice of prepayment is given in connection with a conditional notice
of termination of the Commitments as contemplated by Section 2.8, then such
notice of prepayment may be revoked if such notice of termination is revoked in
accordance with Section 2.8. Promptly following receipt of any such notice
relating to a Revolving Borrowing, the Global Administrative Agent shall advise
the Lenders of the contents thereof. Each partial prepayment of any Revolving
Borrowing shall be in an amount that would be permitted in the case of an
advance of a Revolving Borrowing of the same Type as provided in Section 2.2.
Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans
included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.12 and compensation for break
funding, to the extent required by Section 2.15.

         SECTION 2.11 Fees.

         (a) Borrower agrees to pay to the Global Administrative Agent for the
account of each Lender a facility fee (the "Facility Fee"), which shall accrue
at the Applicable Rate on the daily amount of the Commitment of such Lender
(whether used or unused) during the period from and including the Global
Effective Date to but excluding the earlier to occur of (i) the date on which
such Commitment terminates (except for termination of the Commitment of the
assigning Lender pursuant to Section 10.4(b)) or (ii) the Maturity Date;
provided that, if such Lender continues to have any Revolving Credit Exposure
after its Commitment terminates, then such Facility Fee shall continue to accrue
on the daily amount of such Lender's Revolving Credit Exposure from and
including the date on which its Commitment terminates to but excluding the date
on which such Lender ceases to have any Revolving Credit Exposure. Accrued
Facility Fees shall be payable in arrears on the first day of, April, July and
October and the second day of January of each year and on the date on which the
Commitments terminate, commencing on the first such date to occur after the date
hereof; provided that any Facility Fees accruing after the date on which the
Commitments terminate shall be payable on demand. All Facility Fees shall be
computed on the basis of a year of 365 days (or 366 days in a leap year) and
shall be payable for the actual number of days elapsed (including the first day
but excluding the last day).

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

         (c) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Global Administrative Agent for
distribution, in the case of Facility Fees, to the Lenders. Fees paid shall not
be refundable under any circumstances.

         SECTION 2.12 Interest.

         (a) The Loans comprising each ABR Borrowing shall bear interest on the
daily amount outstanding at the Alternate Base Rate.

                                       26
<PAGE>

         (b) The Loans comprising each Eurodollar Borrowing shall bear interest
on the daily amount outstanding (i) in the case of a Eurodollar Revolving Loan,
at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing
plus the Applicable Rate, or (ii) in the case of a Eurodollar Competitive Loan,
at the LIBO Rate for the Interest Period in effect for such Borrowing plus (or
minus, as applicable) the Margin applicable to such Loan.

         (c) Each Fixed Rate Loan shall bear interest on the daily amount
outstanding at the Fixed Rate applicable to such Loan.

         (d) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by Borrower hereunder is not paid
when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the preceding paragraphs
of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Loans as provided in paragraph (a) of this Section.

         (e) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Revolving Loans on the
Maturity Date; provided that (i) interest accrued pursuant to paragraph (d) of
this Section shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Loan, accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment, (iii) in
the event of any conversion of any Eurodollar Revolving Loan prior to the end of
the current Interest Period therefor, accrued interest on such Loan shall be
payable on the effective date of such conversion, and (iv) with respect to any
Declining Lender, accrued interest shall be paid upon the termination of the
Commitment of such Lender.

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

         SECTION 2.13 Alternate Rate of Interest. If prior to the commencement
of any Interest Period for a Eurodollar Borrowing:

                  (i) the Global Administrative Agent determines (which
         determination shall be conclusive absent demonstrable error) that
         adequate and reasonable means do not exist for ascertaining the
         Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest
         Period; or

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

                                       27
<PAGE>

then the Global Administrative Agent shall give notice thereof to Borrower and
the Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Global Administrative Agent notifies Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Revolving Borrowing to, or
continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be
ineffective, (ii) if any Borrowing Request requests a Eurodollar Revolving
Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any
request by Borrower for a Eurodollar Competitive Borrowing shall be ineffective;
provided that (A) if the circumstances giving rise to such notice do not affect
all the Lenders, then requests by Borrower for Eurodollar Competitive Borrowings
may be made to Lenders that are not affected thereby and (B) if the
circumstances giving rise to such notice affect only one Type of Borrowings,
then the other Type of Borrowings shall be permitted.

         SECTION 2.14 Increased Costs.

         (a) If any Change in Law shall:

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

                  (ii) impose on any Lender or the London interbank market any
         other condition affecting this Agreement or Eurodollar Loans or Fixed
         Rate Loans made by such Lender;

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

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

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section (together with the
calculation thereof) shall be delivered to Borrower and shall be conclusive
absent demonstrable error. Borrower shall pay such Lender the amount shown as
due on any such certificate within 10 days after receipt thereof.

                                       28
<PAGE>

         (d) Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender
notifies Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

         (e) Notwithstanding the foregoing provisions of this Section, a Lender
shall not be entitled to compensation pursuant to this Section in respect of any
Competitive Loan if the Change in Law that would otherwise entitle it to such
compensation shall have been publicly announced prior to submission of the
Competitive Bid pursuant to which such Loan was made.

         SECTION 2.15 Break Funding Payments. In the event of (a) the payment of
any principal of any Eurodollar Loan or Fixed Rate Loan other than on the last
day of an Interest Period applicable thereto (including as a result of an Event
of Default), (b) the conversion of any Eurodollar Loan other than on the last
day of the Interest Period applicable thereto, (c) the failure to borrow,
convert, continue or prepay any Revolving Loan on the date specified in any
notice delivered pursuant hereto (regardless of whether such notice may be
revoked under Section 2.10(b) and is revoked in accordance therewith), (d) the
failure to borrow any Competitive Loan after accepting the Competitive Bid to
make such Loan, or (e) the assignment of any Eurodollar Loan or Fixed Rate Loan
other than on the last day of the Interest Period applicable thereto as a result
of a request by Borrower pursuant to either Section 2.6, or Section 2.18 then,
in any such event, Borrower shall compensate each Lender for the loss, cost and
expense attributable to such event. In the case of a Eurodollar Loan, such loss,
cost or expense to any Lender shall be deemed to include an amount determined by
such Lender to be the excess, if any, of (i) the amount of interest which would
have accrued on the principal amount of such Loan had such event not occurred,
at the Adjusted LIBO Rate that would have been applicable to such Loan, for the
period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
for the period that would have been the Interest Period for such Loan), over
(ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive,
together with the calculation thereof, pursuant to this Section shall be
delivered to Borrower and the Global Administrative Agent and shall be
conclusive absent demonstrable error. Borrower shall pay to the Global
Administrative Agent for the account of such Lender the amount shown as due on
any such certificate within 10 days after receipt thereof.

         SECTION 2.16 Taxes.

         (a) Any and all payments by or on account of any obligation of Borrower
hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if Borrower shall be required to
deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum
payable shall be increased as necessary so that after

                                       29
<PAGE>

making all required deductions (including deductions applicable to additional
sums payable under this Section) the Global Administrative Agent or Lender (as
the case may be) receives an amount equal to the sum it would have received had
no such deductions been made, (ii) Borrower shall make such deductions and (iii)
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

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

         (c) Borrower shall pay the Global Administrative Agent and each Lender,
within 10 days after written demand therefor, the full amount of any Indemnified
Taxes or Other Taxes paid by the Global Administrative Agent or such Lender, as
the case may be, on or with respect to any payment by or on account of any
obligation of Borrower hereunder (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section)
and any penalties, interest and reasonable expenses arising therefrom or with
respect thereto (other than any such penalties or interest arising through the
failure of the Global Administrative Agent or Lender to act as a reasonably
prudent agent or lender, respectively), whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to Borrower by a Lender, or by the Global Administrative
Agent on its own behalf or on behalf of a Lender, shall be conclusive absent
demonstrable error.

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

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

         SECTION 2.17 Payments Generally; Pro Rata Treatment; Sharing of
Set-offs.

         (a) Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest or fees, or of amounts payable under
Section 2.14, 2.15 or 2.16, or otherwise) prior to 1:00 p.m., New York City
time, on the date when due, in immediately available funds, without set-off or
counterclaim. All such payments shall be made to the Global Administrative
Agent, c/o Loan & Agency Services Group, One Chase Manhattan Plaza, 8th Floor,
New York, New York 10081, attention: Lisa Pucciarelli, telephone: (212)
552-7446, facsimile: (212) 552-5777, except that payments pursuant to Sections
2.14, 2.16 and 10.3 shall be made directly to the Persons entitled thereto. The
Global Administrative Agent shall distribute any such payments received by it
for the account of any other Person to the appropriate

                                       30
<PAGE>

recipient promptly following receipt thereof. If any payment hereunder shall be
due on a day that is not a Business Day, the date for payment shall be extended
to the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension.
All payments hereunder shall be made in dollars.

         (b) If at any time insufficient funds are received by and available to
the Global Administrative Agent to pay fully all amounts of principal, interest
and fees then due hereunder, such funds shall be applied (i) first, towards
payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties, and (ii) second, towards payment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties. If insufficient funds are received due to
Borrower's entitlement to withhold amounts on account of Excluded Taxes in
relation to a particular Lender, such insufficiency shall not be subject to this
Section 2.17(b) but shall be withheld from and shall only affect payments made
to such Lender.

         (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Revolving Loans resulting in such Lender receiving
payment of a greater proportion of the aggregate amount of its Revolving Loans
and accrued interest thereon than the proportion received by any other Lender,
then the Lender receiving such greater proportion shall purchase (for cash at
face value) participations in the Revolving Loans of other Lenders to the extent
necessary so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Revolving Loans; provided that (i) if any
such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by Borrower pursuant to and in accordance with the express terms of
this Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to Borrower or any Subsidiary or Affiliate thereof (as
to which the provisions of this paragraph shall apply). Borrower consents to the
foregoing and agrees, to the extent it may effectively do so under applicable
law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against Borrower rights of set-off and counterclaim
with respect to such participation as fully as if such Lender were a direct
creditor of Borrower in the amount of such participation.

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

                                       31
<PAGE>

greater of the Federal Funds Effective Rate and a rate determined by the Global
Administrative Agent in accordance with banking industry rules on interbank
compensation.

         (e) If any Lender shall fail to make any payment required to be made by
it pursuant to Section 2.17(d), then the Global Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Global Administrative Agent for the account of such
Lender to satisfy such Lender's obligations under such Section until all such
unsatisfied obligations are fully paid.

         SECTION 2.18 Mitigation Obligations; Replacement of Lenders.

         (a) If any Lender requests compensation under Section 2.14, or if
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.14 or 2.16, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

         (b) If any Lender requests compensation under Section 2.14, or if
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16,
or if any Lender defaults in its obligation to fund Loans hereunder, then
Borrower may upon notice to such Lender and the Global Administrative Agent,
require such Lender to assign and delegate, without recourse or expense to, or
warranty by, such Lender (in accordance with and subject to the restrictions
contained in Section 10.4), all its interests, rights and obligations under this
Agreement (other than any outstanding Competitive Loans held by it) to an
assignee designated by Borrower which meets the requirements of Section 10.4(b)
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that (i) Borrower shall have received
the prior written consent of the Global 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 Loans (other than
Competitive Loans), accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding
principal and accrued interest and fees) or Borrower (in the case of all other
amounts), (iii) the assignee and assignor shall have entered into an Assignment
and Acceptance, and (iv) in the case of any such assignment resulting from a
claim for compensation under Section 2.14 or payments required to be made
pursuant to Section 2.16, such assignment will result in a reduction in such
compensation or payments.

         SECTION 2.19 Currency Conversion and Currency Indemnity.

         (a) Payments in Agreed Currency. Borrower shall make payment relative
to any Obligation in the currency (the "Agreed Currency") in which the
Obligation was effected. If any payment is received on account of any Obligation
in any currency (the "Other Currency") other

                                       32
<PAGE>

than the Agreed Currency (whether voluntarily or pursuant to an order or
judgment or the enforcement thereof or the realization of any security or the
liquidation of Borrower or otherwise howsoever), such payment shall constitute a
discharge of the liability of Borrower hereunder and under the other Loan
Documents in respect of such obligation only to the extent of the amount of the
Agreed Currency which the relevant Lender or Agent, as the case may be, is able
to purchase with the amount of the Other Currency received by it on the Business
Day next following such receipt in accordance with its normal procedures and
after deducting any premium and costs of exchange.

         (b) Conversion of Agreed Currency into Judgment Currency. If, for the
purpose of obtaining or enforcing judgment in any court in any jurisdiction, it
becomes necessary to convert into a particular currency (the "Judgment
Currency") any amount due in the Agreed Currency then the conversion shall be
made on the basis of the rate of exchange prevailing on the next Business Day
following the date such judgment is given and in any event Borrower shall be
obligated to pay the Agents and the Lenders any deficiency in accordance with
Section 2.19(c). For the foregoing purposes "rate of exchange" means the rate at
which the relevant Lender or Agent, as applicable, in accordance with its normal
banking procedures is able on the relevant date to purchase the Agreed Currency
with the Judgment Currency after deducting any premium and costs of exchange.

         (c) Circumstances Giving Rise to Indemnity. If (i) any Lender or any
Agent receives any payment or payments on account of the liability of Borrower
hereunder pursuant to any judgment or order in any Other Currency, and (ii) the
amount of the Agreed Currency which the relevant Lender or Agent, as applicable,
is able to purchase on the Business Day next following such receipt with the
proceeds of such payment or payments in accordance with its normal procedures
and after deducting any premiums and costs of exchange is less than the amount
of the Agreed Currency due in respect of such obligations immediately prior to
such judgment or order, then Borrower on demand shall, and Borrower hereby
agrees to, indemnify and save the Lenders and the Agents harmless from and
against any loss, cost or expense arising out of or in connection with such
deficiency.

         (d) Indemnity Separate Obligation. The agreement of indemnity provided
for in Section 2.19(c) shall constitute an obligation separate and independent
from all other obligations contained in this Agreement, shall give rise to a
separate and independent cause of action, shall apply irrespective of any
indulgence granted by the Lenders or Agents or any of them from time to time,
and shall continue in full force and effect notwithstanding any judgment or
order for a liquidated sum in respect of an amount due hereunder or under any
judgment or order.

         SECTION 2.20 Additional Borrowers.

         (a) A Person which is a Restricted Subsidiary which is a resident of,
and domiciled in, the United States may become an Additional Borrower with
respect hereto, and shall be bound by and entitled to the benefits and
obligations of this Agreement as a Borrower hereunder to the same extent as any
other Borrower, upon the fulfillment of the following conditions:

                  (i) Resolutions and Officers' Certificates. Such Person shall
         deliver all the items identified in Section 4.1(a) with respect to such
         Person.

                                       33
<PAGE>

                  (ii) Certificate. An Authorized Officer of each Borrower shall
         have delivered to the Global Administrative Agent a certificate stating
         that such Person is a Restricted Subsidiary of the Parent which is
         resident of, and domiciled in, the United States.

                  (iii) No Default. No Default or Event of Default shall have
         occurred and be continuing.

                  (iv) Representations and Warranties. The representations and
         warranties in Article III hereto are true and correct with respect to
         such Person, mutatis mutandis, as of the date such Person executes the
         Additional Borrower Counterpart described in clause (v) below.

                  (v) Additional Borrower Counterpart. Such Person shall execute
         an Additional Borrower Counterpart to this Agreement, substantially in
         the form of Exhibit J (the "Additional Borrower Counterpart") or such
         other agreement in form and substance satisfactory to the Global
         Administrative Agent.

                  (vi) Opinions of Counsel. The Global Administrative Agent
         shall have received legal opinions, dated as of the date such Person
         executes the Additional Borrower Counterpart described above, addressed
         to the Agents and the Lenders, having substantially the same coverage
         as those opinions attached hereto as Exhibits A and B and in form and
         substance acceptable to the Global Administrative Agent, in its
         reasonable discretion.

                  (vii) Approval. The Global Administrative Agent shall have
         approved the addition of such Person as an Additional Borrower, such
         approval not to be unreasonably withheld.

         (b) Upon fulfillment of the conditions in this Section 2.20(a), the
Global Administrative Agent will promptly notify each Lender of the date that
such Person becomes an Additional Borrower hereunder.

                                  ARTICLE III

                         Representations and Warranties

         In order to induce the Lenders and the Agents to enter into this
Agreement and the Lenders to make Loans hereunder, Borrower represents and
warrants unto the Agents and each Lender as set forth in this Article III.

         SECTION 3.1 Organization. Borrower is a corporation, and each of its
Subsidiaries is a corporation or other legal entity, in either case duly
incorporated or otherwise properly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation or organization and
has all requisite authority, permits and approvals, and is in good standing to
conduct its business in each jurisdiction in which its business is conducted
where the failure to so qualify would have a Material Adverse Effect.

                                       34
<PAGE>

         SECTION 3.2 Authorization and Validity. The execution, delivery and
performance by Borrower of this Agreement and each other Loan Document executed
or to be executed by it, are within Borrower's corporate powers, have been duly
authorized by all necessary corporate action on behalf of it, and do not (a)
contravene Borrower's articles of incorporation or other organizational
documents, as the case may be; (b) contravene any material contractual
restriction, law or governmental regulation or court decree or order binding on
or affecting Borrower or any Subsidiary; or (c) result in, or require the
creation or imposition of, any Lien, not permitted by Section 7.1, on any of
Borrower's or any Subsidiary's properties. This Agreement constitutes, and each
other Loan Document executed by Borrower will, on the due execution and delivery
thereof, constitute, the legal, valid and binding obligations of Borrower
enforceable in accordance with their respective terms subject as to enforcement
only to bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditor rights generally and to general principles
of equity.

         SECTION 3.3 Government Approval and Regulation. No authorization or
approval or other action by, and no notice to or filing with, any governmental
authority or regulatory body or other Person is required for the due execution,
delivery or performance by Borrower of this Agreement or any other Loan
Document. Neither Borrower nor any of its Subsidiaries is an "investment
company," within the meaning of the Investment Company Act of 1940, as amended,
or 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," within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

         SECTION 3.4 Pension and Welfare Plans. During the
twelve-consecutive-month period prior to the date of the execution and delivery
of this Agreement and prior to the date of any Borrowing hereunder, no steps
have been taken to terminate any Pension Plan, and no contribution failure has
occurred with respect to any Pension Plan sufficient to give rise to a lien
under Section 302(f) of ERISA. No condition exists or event or transaction has
occurred with respect to any Pension Plan which would result in the incurrence
by Borrower or any member of the Controlled Group of any liability, fine or
penalty in excess of $25,000,000. Neither Borrower nor any member of the
Controlled Group has any contingent liability with respect to any
post-retirement benefit under a Welfare Plan, other than liability for
continuation coverage described in Part 6 of Title I of ERISA.

         SECTION 3.5 Regulation U. Borrower is not engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock, and no
proceeds of any Loans will be used for a purpose which violates, or would be
inconsistent with, Regulation U. Terms for which meanings are provided in
Regulations U are used in this Section with such meanings.

         SECTION 3.6 Taxes. Borrower and each of its Subsidiaries has to the
best knowledge of Borrower after due investigation filed all tax returns and
reports required by law to have been filed by it and has paid all taxes and
governmental charges thereby shown to be owing, except any such taxes or charges
which are being contested in good faith by appropriate proceedings and for which
adequate reserves in accordance with GAAP shall have been set aside on its books
or which the failure to file or pay could not reasonably be expected to have a
Material Adverse Effect.

<PAGE>

         SECTION 3.7 Subsidiaries; Restricted Subsidiaries. Schedule 3.7 hereto
contains an accurate list of all of the presently existing Subsidiaries,
including, without limitation, Restricted Subsidiaries, of Borrower as of the
date of this Agreement, setting forth their respective jurisdictions of
incorporation or organization and the percentage of their respective capital
stock or, the revenue share attributable to the general and limited partnership
interests, as the case may be, owned by Borrower or other Subsidiaries. All of
the issued and outstanding shares of capital stock of such Subsidiaries which
are corporations have been duly authorized and issued and are fully paid and
non-assessable.

                                   ARTICLE IV

                                   Conditions

         SECTION 4.1 Effectiveness. This Agreement shall become effective upon
the prior or concurrent satisfaction of each of the conditions precedent set
forth in this Section 4.1.

         (a)      Resolutions and Officers Certificates. The Global
                  Administrative Agent shall have received from Borrower a
                  certificate, dated the Global Effective Date, of the Secretary
                  or Assistant Secretary of Borrower as to (i) resolutions of
                  its governing board, then in full force and effect authorizing
                  the execution, delivery and performance of this Agreement and
                  each other Loan Document to be executed by it; (ii) the
                  incumbency and signatures of those of its officers authorized
                  to act with respect to this Agreement and each other Loan
                  Document executed by it; and (iii) its articles of
                  incorporation and bylaws; upon which certificates each Lender
                  may conclusively rely until it shall have received a further
                  certificate of an authorized officer of Borrower canceling or
                  amending such prior certificate.

         (b)      Existing Facilities. The Global Administrative Agent shall
                  have received a certificate, signed by an Authorized Officer
                  of Borrower, stating that Borrower or its Subsidiaries have
                  repaid in full and terminated the Existing Global Credit
                  Facilities concurrently with the effectiveness of the Combined
                  Credit Agreements.

         (c)      Opinions of Counsel. The Global Administrative Agent shall
                  have received opinions, dated the Global Effective Date,
                  addressed to the Global Administrative Agent, the other Agents
                  and all Lenders, from (i) Jeffrey B. King, Esq., Corporate
                  Counsel and Assistant Secretary of Borrower, in substantially
                  the form attached hereto as Exhibit A, and (ii) Chamberlain,
                  Hrdlicka, White, Williams & Martin, counsel to Borrower, in
                  substantially the form attached hereto as Exhibit B.

         (d)      Closing Fees and Expenses. The Global Administrative Agent
                  shall have received for its own account, or for the account of
                  each Lender and other Agent, as the case may be, all fees,
                  costs and expenses due and payable pursuant hereto.

         (e)      Financial Statements. The Global Administrative Agent shall
                  have received a certificate, signed by an Authorized Officer
                  of Borrower, stating that the audited consolidated financial
                  statements of Borrower and its Subsidiaries for fiscal year
                  2001 (the "2001 Financials") fairly present Borrower's
                  financial condition and

                                       36
<PAGE>

                  results of operations and that prior to the Global Effective
                  Date no material adverse change in the condition or operations
                  of Borrower and its Subsidiaries, taken as a whole, from that
                  reflected in the 2001 Financials has occurred and is
                  continuing.

         (f)      Environmental Warranties. In the ordinary course of its
                  business, Borrower conducts an ongoing review of the effect of
                  existing Environmental Laws on the business, operations and
                  properties of Borrower and its Subsidiaries, in the course of
                  which it attempts to identify and evaluate associated
                  liabilities and costs (including, without limitation, any
                  capital or operating expenditures required for clean-up or
                  closure of properties presently or previously owned, any
                  capital or operating expenditures required to achieve or
                  maintain compliance with environmental protection standards
                  imposed by law or as a condition of any license, permit or
                  contract, any related constraints on operating activities,
                  including any periodic or permanent shutdown of any facility
                  or reduction in the level of or change in the nature of
                  operations conducted thereat and any actual or potential
                  liabilities to third parties, including employees, and any
                  related costs and expenses). On the basis of this review, the
                  Global Administrative Agent shall have received a certificate,
                  signed by an Authorized Officer of Borrower, stating that
                  after such review Borrower has reasonably concluded that
                  existing Environmental Laws are unlikely to have a Material
                  Adverse Effect, or that Borrower has established adequate
                  reserves in respect of any required clean-up.

         (g)      Global Effectiveness Notice. The Global Administrative Agent
                  shall have received the Global Effectiveness Notice.

         (h)      Other Combined Credit Agreements. The Global Administrative
                  Agent shall have received copies of the executed (i)
                  Australian Credit Agreement and the other Australian Loan
                  Documents, (ii) Canadian Credit Agreement and the other
                  Canadian Loan Documents and (iii) 364-Day Credit Agreement and
                  the other 364-Day Loan Documents.

         (i)      Litigation. The Global Administrative Agent shall have
                  received a certificate, signed by an Authorized Officer of
                  Borrower, stating that no litigation, arbitration,
                  governmental proceeding, Tax claim, dispute or administrative
                  or other proceeding shall be pending or, to the knowledge of
                  Borrower, threatened against Borrower or any of its
                  Subsidiaries which could reasonably be expected to have a
                  Material Adverse Effect or which purports to affect the
                  legality, validity or enforceability of this Agreement or any
                  other Loan Document.

         (j)      Other Documents. The Global Administrative Agent shall have
                  received such other instruments and documents as any of the
                  Agents or their counsel may have reasonably requested.

The Global Administrative Agent shall notify Borrower, the other Agents and the
Lenders of the Global Effective Date, and such notice shall be conclusive and
binding. Notwithstanding the foregoing, the obligations of the Lenders to make
Loans hereunder shall not become effective

                                       37
<PAGE>

unless each of the foregoing conditions is satisfied (or waived pursuant to
Section 10.2) at or prior to 3:00 p.m., New York City time, on July 31, 2002
(and, in the event such conditions are not so satisfied or waived, the
Commitments shall terminate at such time).

         SECTION 4.2 All Loans. The obligation of each Lender to fund any Loan
which results in an increase in the aggregate outstanding principal amount of
Loans under this Agreement on the occasion of any Borrowing shall be subject to
the satisfaction of each of the conditions precedent set forth in this Section
4.2.

         (a)      Compliance with Warranties and No Default. Both before and
                  after giving effect to any Borrowing, the following statements
                  shall be true and correct: (1) the representations and
                  warranties set forth in Article III shall be true and correct
                  with the same effect as if then made (unless stated to relate
                  solely to an earlier date, in which case such representations
                  and warranties shall be true and correct as of such earlier
                  date); and (b) no Default or Event of Default shall have then
                  occurred and be continuing.

         (b)      Borrowings. The Global Administrative Agent shall have
                  received a Borrowing Request for any Revolving Borrowing, or a
                  Competitive Borrowing Request and a Competitive Bid
                  Accept/Reject Letter for any Competitive Borrowing.

                                    ARTICLE V

                              Affirmative Covenants

         Until the Commitments have expired or been terminated and all
Obligations shall have been paid in full and unless the Required Lenders shall
otherwise consent in writing, Borrower covenants and agrees with the Lenders
that:

         SECTION 5.1 Financial Reporting and Notices. Apache will furnish, or
will cause to be furnished, to each Lender and the Global Administrative Agent
copies of the following financial statements, reports, notices and information:

         (a)      within 90 days after the end of each Fiscal Year of Apache, a
                  copy of the audited annual report for such fiscal year for
                  Apache and its Subsidiaries, including therein consolidated
                  balance sheets of Apache and its Subsidiaries as of the end of
                  such fiscal year and consolidated statements of earnings and
                  cash flow of Apache and its Subsidiaries for such fiscal year,
                  in each case certified (without qualification) by independent
                  public accountants of nationally recognized standing selected
                  by Apache;

         (b)      within 45 days after the end of each of the first three fiscal
                  quarters of each fiscal year of Apache commencing with the
                  fiscal quarter ending June 30, 2002, unaudited consolidated
                  balance sheets of Apache and its Subsidiaries as of the end of
                  such fiscal quarter and consolidated statements of earnings
                  and cash flow of Apache and its Subsidiaries for such fiscal
                  quarter and for the period commencing

                                       38
<PAGE>

                  at the end of the previous fiscal year and ending with the end
                  of such fiscal quarter, certified by an Authorized Officer of
                  Apache;

         (c)      together with the financial statements described in (a) and
                  (b), above a compliance certificate, in substantially the form
                  of Exhibit C or any other form approved by the Global
                  Administrative Agent, executed by an Authorized Officer of
                  Apache;

         (d)      within five (5) days after the occurrence of each Default, a
                  statement of an Authorized Officer of Apache setting forth
                  details of such Default and the action which Borrower has
                  taken and proposes to take with respect thereto;

         (e)      promptly after the sending or filing thereof, copies of all
                  material public filings, reports and communications from
                  Borrower, and all reports and registration statements which
                  Borrower or any of its Subsidiaries files with the Securities
                  and Exchange Commission or any national securities exchange;

         (f)      immediately upon becoming aware of the institution of any
                  steps by Borrower or any other Person to terminate any Pension
                  Plan, or the failure to make a required contribution to any
                  Pension Plan if such failure is sufficient to give rise to a
                  Lien under Section 302(f) of ERISA, or the taking of any
                  action with respect to a Pension Plan which would reasonably
                  be expected to result in the requirement that Borrower furnish

         Each of the Lenders hereby irrevocably appoints JPMorgan Chase Bank as
Global Administrative Agent, Bank of America, N.A. as Global Syndication Agent,
Citibank, N.A. as Global Documentation Agent, Bank of America, N.A. and Wachovia
Bank, National Association as U.S. Co-Syndication Agents, and Citibank, N.A. and
Union Bank of California, N.A. as U.S. Co-Documentation Agents, and authorizes
each such Agent to take such actions on its behalf and to exercise such powers
as are delegated to such Agent by the terms hereof, together with such actions
and powers as are reasonably incidental thereto.

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

         The Agents shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing,
(a) the Agents shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing, (b) each Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that such Agent is required to exercise in writing by the
Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 10.2), and (c) except
as expressly set forth herein, the Agents shall not have any duty to disclose,
and shall not be liable for the failure to disclose, any information relating to
Borrower or any of its Subsidiaries that is communicated to or obtained by the
bank serving as such Agent or any of its Affiliates in any capacity. Each Agent
shall not be liable for any action taken or not taken by it with the consent or
at the request of the Required Lenders (or such other number or percentage of
the Lenders as shall be necessary under the circumstances as provided in Section
10.2) or in the absence of its own gross negligence or willful misconduct. Each
Agent shall be deemed not to have knowledge of any Default unless and until
written notice thereof is given to such Agent by Borrower or a Lender, and such
Agent shall not be responsible for or have any duty to ascertain or inquire into
(i) any statement, warranty or representation made in or in connection with this
Agreement, (ii) the contents of any certificate, report or other document
delivered hereunder or in connection herewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm receipt of items expressly required to be delivered to such
Agent.

         The Global Administrative Agent and the other Agents shall be entitled
to rely upon, and shall not incur any liability for relying upon, any notice,
request, certificate, consent, statement, instrument, document or other writing
believed by it to be genuine and to have been signed or sent by the proper
Person. The Global Administrative Agent and the other Agents also may rely

                                       46
<PAGE>

upon any statement made to it orally or by telephone and believed by it to be
made by the proper Person, and shall not incur any liability for relying
thereon. The Global Administrative Agent and the other Agents may consult with
legal counsel (who may be counsel for Borrower), independent accountants and
other experts selected by it, and shall not be liable for any action taken or
not taken by it in accordance with the advice of any such counsel, accountants
or experts.

         Any Agent may perform any and all its duties and exercise its rights
and powers by or through any one or more sub-agents appointed by such Agent. Any
Agent and any such sub-agent may perform any and all its duties and exercise its
rights and powers through their respective Related Parties. The exculpatory
provisions of the preceding paragraphs shall apply to any such sub-agent and to
the Related Parties of such Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as an Agent.

         Subject to the appointment and acceptance of a successor Global
Administrative Agent as provided in this paragraph, the Global Administrative
Agent may resign at any time by notifying the Lenders and Borrower. Upon any
such resignation, Borrower shall have the right, in consultation with the
Combined Required Lenders, to appoint one of the Lenders as a successor. If no
successor shall have been so appointed by Borrower and shall have accepted such
appointment within 30 days after the retiring Global Administrative Agent gives
notice of its resignation, then the retiring Global Administrative Agent may, on
behalf of the Lenders, appoint a successor Global Administrative Agent which
shall be a bank with an office in New York, New York, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Global Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Global
Administrative Agent, and the retiring Global Administrative Agent shall be
discharged from its duties and obligations hereunder. The fees payable by
Borrower to a successor Global Administrative Agent shall be the same as those
payable to its predecessor unless otherwise agreed between Borrower and such
successor. After the Global Administrative Agent's resignation hereunder, the
provisions of this Article and Section 10.3 shall continue in effect for the
benefit of such retiring Global Administrative Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as Global Administrative Agent.

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

         (c) if to any other Lender, to it at its address (or telecopy number)
provided to the Global Administrative Agent and Borrower or as set forth in its
Administrative Questionnaire.

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

         SECTION 10.2 Waivers; Amendments.

         (a) No failure or delay by the Global Administrative Agent or any
Lender in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Global Administrative Agent and
the Lenders hereunder are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the Global
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

         (b) Any of the Combined Loan Documents or any provision thereof may be
waived, amended or modified pursuant to an agreement or agreements in writing
entered into by Borrower and the Combined Required Lenders or by Borrower and
the Global Administrative

                                       49
<PAGE>

Agent with the consent of the Combined Required Lenders; provided that the same
waiver, amendment or modification is requested by Borrower in connection with
each of the Combined Credit Agreements; and provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of (i)
the Lenders described in the first proviso of Section 10.2(c) without the prior
written consent of each Lender affected thereby and (ii) the Global
Administrative Agent without the prior written consent of the Global
Administrative Agent.

         (c) Except as provided for in Section 10.2(b) above, neither this
Agreement nor any other Loan Document nor any provision hereof or thereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by Borrower and the Required Lenders or by Borrower and the
Global Administrative Agent with the consent of the Required Lenders; provided
that no such agreement shall (i) increase the Commitment of any Lender or the
Commitments without the written consent of such Lender or each Lender,
respectively, (ii) reduce the principal amount of any Loan or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment of the principal amount of any Loan, or any interest thereon, or any
fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without
the written consent of each Lender affected thereby, (iv) change Section 2.17(b)
or (c) in a manner that would alter the pro rata sharing of payments required
thereby, without the written consent of each Lender, or (v) change any of the
provisions of this Section or the definition of "Required Lenders", "Combined
Required Lenders" or any other provision hereof or thereof specifying the number
or percentage of Lenders required to waive, amend or modify any rights hereunder
or thereunder or make any determination or grant any consent hereunder or
thereunder, without the written consent of each Lender; provided further that no
such agreement shall amend, modify or otherwise affect the rights or duties of
the Global Administrative Agent hereunder or thereunder without the prior
written consent of the Global Administrative Agent.

         SECTION 10.3 Expenses; Indemnity; Damage Waiver.

         (a) Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Agents and their Affiliates, including the reasonable fees,
charges and disbursements of counsel for the Agents, in connection with the
syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement or any amendments, modifications or waivers of
the provisions hereof (whether or not the transactions contemplated hereby or
thereby shall be consummated) and (ii) all reasonable out-of-pocket expenses
incurred by the Agents or any Lender, including the fees, charges and
disbursements of any counsel for the Agents or any Lender, in connection with
the enforcement or protection of its rights in connection with this Agreement,
including its rights under this Section, or in connection with the Loans made
hereunder, including all such out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or this
Agreement.

         (b) Borrower shall indemnify the Agents and each Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the
reasonable fees, charges and disbursements of any counsel for any

                                       50
<PAGE>

Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of (i) the execution or delivery of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the Transactions or any other transactions contemplated hereby, (ii) any Loan
or the actual or proposed use of the proceeds therefrom, (iii) any actual or
alleged presence or release of Hazardous Materials on or from any property owned
or operated by Borrower or any of its Subsidiaries, or any Environmental
Liability related in any way to Borrower or any of its Subsidiaries, or (iv) any
actual or prospective claim, litigation, investigation or proceeding relating to
any of the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (i) resulted from the
gross negligence or willful misconduct of such Indemnitee or (ii) arise in
connection with any issue in litigation commenced by Borrower or any of its
Subsidiaries against any Indemnitee for which a final judgment is entered in
favor of Borrower or any of its Subsidiaries against such Indemnitee.

         (c) To the extent that Borrower fails to pay any amount required to be
paid by it to the Global Administrative Agent under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Global Administrative Agent,
such Lender's Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid
amount; provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or
asserted against the Global Administrative Agent.

         (d) To the extent permitted by applicable law, Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions or any Loan or the use of the proceeds thereof, except for any such
claim arising from such Indemnitee's gross negligence or willful misconduct.

         (e) All amounts due under this Section shall be payable not later than
thirty (30) days after written demand therefor.

         SECTION 10.4 Successors and Assigns.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that Borrower may not assign or otherwise transfer any
of its rights or obligations hereunder without the prior written consent of each
Lender (and any attempted assignment or transfer by Borrower without such
consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Related Parties of each of the Global
Administrative Agent and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

                                       51
<PAGE>

         (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans at the time owing to it); provided that (i) except
in the case of an assignment to a Lender or an Affiliate of a Lender, each of
Apache and the Global Administrative Agent must give their prior written consent
to such assignment (which consent shall not be unreasonably withheld), (ii)
except in the case of an assignment to a Lender or an Affiliate of a Lender or
an assignment of the entire remaining amount of the assigning Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Global Administrative Agent)
shall be in increments of $1,000,000 and not less than $10,000,000 unless each
of Borrower and the Global Administrative Agent otherwise consent, (iii) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender's rights and obligations under this Agreement, except that
this clause (iii) shall not apply to rights in respect of outstanding
Competitive Loans, (iv) the parties to each assignment shall execute and deliver
to the Global Administrative Agent an Assignment and Acceptance, together with a
processing and recordation fee of $3,500, and (v) the assignee, if it shall not
be a Lender, shall deliver to the Global Administrative Agent an Administrative
Questionnaire; and provided further that any consent of Apache otherwise
required under this paragraph shall not be required if an Event of Default under
Section 8.1 has occurred and is continuing. Subject to acceptance and recording
thereof pursuant to paragraph (d) of this Section, from and after the effective
date specified in each Assignment and Acceptance the assignee thereunder shall
be a party hereto and, to the extent of the interest assigned by such Assignment
and Acceptance, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 2.14, 2.15, 2.16, 2.17, 2.19 and
10.3). Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this paragraph shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with paragraph (e) of this Section.

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

         (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee

                                       52
<PAGE>

referred to in paragraph (b) of this Section and any written consent to such
assignment required by paragraph (b) of this Section, the Global Administrative
Agent shall accept such Assignment and Acceptance and record the information
contained therein in the Register and will provide prompt written notice to
Borrower of the effectiveness of such Assignment. No assignment shall be
effective for purposes of this Agreement unless it has been recorded in the
Register as provided in this paragraph.

         (e) Any Lender may, without the consent of Borrower or the Global
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (i) such Lender's obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) Borrower,
the Global 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, and (iv) if such Participant is not a Lender
or an Affiliate of a Lender, such Lender shall have given notice to Borrower of
the name of the Participant and the amount of such participation. Any agreement
or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement
and to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 10.2(c) that
affects such Participant. Subject to paragraph (f) of this Section, Borrower
agrees that each Participant shall be entitled to the benefits of Sections 2.14,
2.15 and 2.16 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to paragraph (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 10.8 as though it were a Lender, provided such Participant agrees to be
subject to Section 2.17(c) as though it were a Lender.

         (f) A Participant shall not be entitled to receive any greater payment
under Section 2.14, 2.15 or 2.16 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless Borrower shall expressly agree otherwise in writing. A Participant that
would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 2.16 unless Borrower is notified of the participation sold
to such Participant and such Participant agrees, for the benefit of Borrower, to
comply with Section 2.16(e) as though it were a Lender.

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

         SECTION 10.5 Survival. All covenants, agreements, representations and
warranties made by Borrower herein and in the certificates or other instruments
delivered in

                                       53
<PAGE>

connection with or pursuant to this Agreement shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of this Agreement and the making of any Loans, regardless of any
investigation made by any such other party or on its behalf and notwithstanding
that the Global Administrative Agent or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid and so long
as the Commitments have not expired or terminated. The provisions of Sections
2.14, 2.15, 2.16, 2.17, 2.19 and 10.3 and Article IX shall survive and remain in
full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the expiration or termination
of the Commitments or the termination of this Agreement or any provision hereof.

         SECTION 10.6 Counterparts; Integration; Effectiveness. This Agreement
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Global
Administrative Agent constitute the entire contract among the parties relating
to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.1, this Agreement shall become effective when it shall
have been executed by the Global Administrative Agent and when the Global
Administrative Agent shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

         SECTION 10.7 Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

         SECTION 10.8 Right of Setoff. If an Event of Default shall have
occurred and be continuing and the Obligations of Borrower shall have been
accelerated, each Lender and each of its Affiliates is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other obligations at any time owing by such
Lender or Affiliate to or for the credit or the account of any Borrower against
any of and all the obligations of each Borrower now or hereafter existing under
this Agreement held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement and although such obligations
may be unmatured. The rights of each Lender under this Section are in addition
to other rights and remedies (including other rights of setoff) which such
Lender may have.

         SECTION 10.9 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

         SECTION 10.10 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

         SECTION 10.11 Confidentiality. Each of the Agents and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including

                                       55
<PAGE>

accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory or self-regulatory
authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Agreement,
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section, to any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement, (g) with the consent of Borrower or (h) to the extent such
Information (A) becomes publicly available other than as a result of a breach of
this Section by any Person or (B) becomes available to any Agent or any Lender
on a nonconfidential basis from a source other than Borrower or any Person
obligated to maintain the confidentiality of such Information. Prior to
disclosing any Information under clause (c) above, the Agent or Lender required
or asked to make such disclosure shall make a good faith effort to give Borrower
prior notice of such proposed disclosure to permit Borrower to attempt to obtain
a protective order or other appropriate injunctive relief. For the purposes of
this Section, "Information" means all information received from Borrower
relating to Borrower or its business, other than any publicly available
information and such information that is available to any Agent or any Lender on
a nonconfidential basis prior to disclosure by Borrower; provided that, in the
case of information received from Borrower after the date hereof, such
information is clearly identified at the time of delivery as confidential. Any
Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so
if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

         SECTION 10.12 Interest Rate Limitation. It is the intention of the
parties hereto to conform strictly to applicable interest, usury and criminal
laws and, anything herein to the contrary notwithstanding, the obligations of
Borrower to a Lender or any Agent under this Agreement shall be subject to the
limitation that payments of interest shall not be required to the extent that
receipt thereof would be contrary to provisions of law applicable to such Lender
or Agent limiting rates of interest which may be charged or collected by such
Lender or Agent. Accordingly, if the transactions contemplated hereby would be
illegal, unenforceable, usurious or criminal under laws applicable to a Lender
or Agent (including the laws of any jurisdiction whose laws may be mandatorily
applicable to such Lender or Agent notwithstanding anything to the contrary in
this Agreement or any other Loan Document but subject to Section 2.12 hereof)
then, in that event, notwithstanding anything to the contrary in this Agreement
or any other Loan Document, it is agreed as follows:

                  (i) the provisions of this Section shall govern and control;

                  (ii) the aggregate of all consideration which constitutes
         interest under applicable law that is contracted for, taken, reserved,
         charged or received under this Agreement, or under any of the other
         aforesaid agreements or otherwise in connection with this Agreement by
         such Lender or Agent shall under no circumstances exceed the maximum
         amount of interest allowed by applicable law (such maximum lawful
         interest rate, if any, with respect to each Lender and the Agent herein
         called the "Highest Lawful

                                       56
<PAGE>

         Rate"), and any excess shall be cancelled automatically and if
         theretofore paid shall be credited to Borrower by such Lender or Agent
         (or, if such consideration shall have been paid in full, such excess
         refunded to Borrower);

                  (iii) all sums paid, or agreed to be paid, to such Lender or
         Agent for the use, forbearance and detention of the indebtedness of
         Borrower to such Lender or Agent hereunder or under any Loan Document
         shall, to the extent permitted by laws applicable to such Lender or
         Agent, as the case may be, be amortized, prorated, allocated and spread
         throughout the full term of such indebtedness until payment in full so
         that the actual rate of interest is uniform throughout the full term
         thereof;

                  (iv) if at any time the interest provided pursuant to this
         Section or any other clause of this Agreement or any other Loan
         Document, together with any other fees or compensation payable pursuant
         to this Agreement or any other Loan Document and deemed interest under
         laws applicable to such Lender or Agent, exceeds that amount which
         would have accrued at the Highest Lawful Rate, the amount of interest
         and any such fees or compensation to accrue to such Lender or Agent
         pursuant to this Agreement shall be limited, notwithstanding anything
         to the contrary in this Agreement or any other Loan Document, to that
         amount which would have accrued at the Highest Lawful Rate, but any
         subsequent reductions, as applicable, shall not reduce the interest to
         accrue to such Lender or Agent pursuant to this Agreement below the
         Highest Lawful Rate until the total amount of interest accrued pursuant
         to this Agreement or such other Loan Document, as the case may be, and
         such fees or compensation deemed to be interest equals the amount of
         interest which would have accrued to such Lender or Agent if a varying
         rate per annum equal to the interest provided pursuant to any other
         relevant Section hereof (other than this Section), as applicable, had
         at all times been in effect, plus the amount of fees which would have
         been received but for the effect of this Section; and

                  (v) with the intent that the rate of interest herein shall at
         all times be lawful, and if the receipt of any funds owing hereunder or
         under any other agreement related hereto (including any of the other
         Loan Documents) by such Lender or Agent would cause such Lender to
         charge Borrower a criminal rate of interest, the Lenders and the Agents
         agree that they will not require the payment or receipt thereof or a
         portion thereof which would cause a criminal rate of interest to be
         charged by such Lender or Agent, as applicable, and if received such
         affected Lender or Agent will return such funds to Borrower so that the
         rate of interest paid by Borrower shall not exceed a criminal rate of
         interest from the date this Agreement was entered into.

         SECTION 10.13 Joint and Several Obligations. Each Borrower has
determined that it is in its best interest and in pursuance of its legitimate
business purposes to induce the Lenders to extend credit to the Borrowers
pursuant to this Agreement. Each Borrower acknowledges and represents that the
availability of the Commitments to each of the Borrowers benefits each Borrower
individually and that the Loans made will be for and inure to the benefit of
each of the Borrowers individually and as a group. Accordingly, each Borrower
shall be jointly and severally liable (as a principal and not as a surety,
guarantor or other accommodation party) for each and every representation,
warranty, covenant and obligation to be performed by the Borrowers under this
Agreement and the other Loan Documents, and each Borrower

                                       57
<PAGE>

acknowledges that in extending the credit provided herein the Agent and the
Lenders are relying upon the fact that the Obligations of each Borrower
hereunder are the joint and several obligations of a principal. The invalidity,
unenforceability or illegality of this Agreement or any other Loan Document as
to one Borrower or the release by the Agent or the Lenders of a Borrower
hereunder or thereunder shall not affect the Obligations of the other Borrowers
under this Agreement or the other Loan Documents, all of which shall otherwise
remain valid and legally binding obligations of the other Borrowers.

         SECTION 10.14 NO ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE OTHER
LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE
PARTIES.

Loans have been paid in full, to Eurodollar Loans, unless Borrower shall have
otherwise instructed the Administrative Agent in writing. Upon a Lender making
such Term Loan, such Lender shall have no further Commitment to make additional
Loans.

         SECTION 2.2 Loans and Borrowings.

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

         (b) Subject to Section 2.13, each Borrowing shall be comprised entirely
of ABR Loans or Eurodollar Loans as Borrower may request in accordance herewith.

or foreign branch or Affiliate of such Lender to make such Loan; provided that
any exercise of such option shall not affect the obligation of Borrower to repay
such Loan in accordance with the terms of this Agreement.

Borrowing, such Borrowing shall be in an aggregate amount that is an integral
multiple of $1,000,000 and not less

than $5,000,000 (including any continuation or conversion of existing Loans made
in connection therewith). At the time that each ABR Borrowing is made, such
Borrowing shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 (including any continuation or
conversion of existing Loans made in connection therewith); provided that an ABR
Borrowing may be in an aggregate amount that is equal to the entire unused
balance of the total Commitments. Borrowings of more than one Type and Class may
be outstanding at the same time; provided that there shall not at any time be
more than a total of ten (10) Eurodollar Borrowings outstanding.

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

         SECTION 2.3 Requests for Borrowings. To request a Borrowing, Borrower
shall notify the Global Administrative Agent of such request by telephone (a) in
the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York City
time, three Business Days before the date of the proposed Borrowing or (b) in
the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on
the date of the proposed Borrowing. Each such telephonic Borrowing Request shall
be irrevocable and shall be confirmed promptly by hand delivery or telecopy to
the Global Administrative Agent of a written Borrowing Request in a form
approved by the Global Administrative Agent and signed by Borrower. Each such
telephonic and written Borrowing Request shall specify the following information
in compliance with Section 2.2:

                  (i) the aggregate amount of the requested Borrowing;

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

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

                  (iv) in the case of a Eurodollar Borrowing, the initial
         Interest Period to be applicable thereto, which shall be a period
         contemplated by the definition of the term "Interest Period".

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

         SECTION 2.4 [Intentionally omitted].

         SECTION 2.5 Funding of Borrowings.

         (a) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00
noon, New York City time, to the account of the Global Administrative Agent most
recently designated by it for such

                                       18
<PAGE>

purpose by notice to the Lenders. The Global Administrative Agent will make such
Loans available to Borrower by promptly crediting the amounts so received, in
like funds, to an account of Borrower designated by Borrower from time to time
in a written notice to the Global Administrative Agent executed by two
Authorized Officers of Apache and two Authorized Officers of any Additional
Borrower.

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

         SECTION 2.6 Extension of Revolving Commitment Termination Date and of
Revolving Commitments.

         (a) Subject to the other provisions of this Agreement and provided that
no Event of Default has occurred and is continuing, the total Revolving
Commitments shall be effective for an initial period from the Global Effective
Date to the Original Revolving Commitment Termination Date; provided that the
Revolving Commitment Termination Date, and concomitantly the total Revolving
Commitments, may be extended for successive 364-day periods expiring on the date
which is 364-days from the then scheduled Revolving Commitment Termination Date.
If Borrower shall request in a Certificate of Extension delivered to the Global
Administrative Agent at least 45 days, but no more than 60 days, prior to the
then scheduled Revolving Commitment Termination Date that the Revolving
Commitment Termination Date be extended for 364-days from the then scheduled
Revolving Commitment Termination Date, then the Global Administrative Agent
shall promptly notify each Lender of such request and each Lender shall notify
the Global Administrative Agent, no later than 15 days after such Lender's
receipt of such Certificate of Extension, whether such Lender, in the exercise
of its sole discretion, will extend the Revolving Commitment Termination Date
for such 364-day period. Any Lender which shall not timely notify the Global
Administrative Agent whether it will extend the Revolving Commitment Termination
Date shall be deemed to not have agreed to extend the Revolving Commitment
Termination Date. No Lender shall have any obligation whatsoever to agree to
extend the Revolving Commitment Termination Date. Any agreement to extend the
Revolving Commitment Termination Date by any Lender shall be irrevocable, except
as provided in clause (c) of this Section.

                                       19
<PAGE>

         (b) If all Lenders notify the Global Administrative Agent pursuant to
clause (a) of this Section 2.6 of their agreement to extend the Revolving
Commitment Termination Date, then the Global Administrative Agent shall so
notify each Lender and Borrower, and such extension shall be effective without
other or further action by any party hereto for such additional 364-day period.

         (c) If Lenders constituting at least the Required Lenders approve the
extension of the then scheduled Revolving Commitment Termination Date (such
Lenders agreeing to extend the Revolving Commitment Termination Date herein
called the "Accepting Lenders") and if one or more Lenders shall notify, or be
deemed to notify, the Global Administrative Agent pursuant to clause (a) of this
Section that they will not extend the then scheduled Revolving Commitment
Termination Date (such Lenders herein called the "Declining Lenders"), then (A)
the Global Administrative Agent shall promptly so notify Borrower and the
Accepting Lenders, (B) the Accepting Lenders shall, upon Borrower's election to
extend the then scheduled Revolving Commitment Termination Date in accordance
with clause (i) or (ii) below, extend the then scheduled Revolving Commitment
Termination Date, and (C) Borrower shall, pursuant to a notice delivered to the
Global Administrative Agent, the Accepting Lenders and the Declining Lenders, no
later than the tenth (10th) day following the date by which each Lender is
required, pursuant to clause (a) of this Section to approve or disapprove the
requested extension of the total Revolving Commitments, either:

                  (i) elect to extend the Revolving Commitment Termination Date
         and direct the Declining Lenders to terminate their Revolving
         Commitments, which termination shall become effective on the date which
         would have been the Revolving Commitment Termination Date except for
         the operation of this Section. On the date which would have been the
         Revolving Commitment Termination Date except for the operation of this
         Section, (x) Borrower shall deliver a notice of the effectiveness of
         such termination to the Declining Lenders with a copy to the Global
         Administrative Agent and (y) Borrower shall pay in full in immediately
         available funds all Obligations of Borrower owing to the Declining
         Lenders, including any amounts required pursuant to Section 2.15, and
         (z) upon the occurrence of the events set forth in clauses (x) and (y),
         the Declining Lenders shall each cease to be a Lender hereunder for all
         purposes, other than for purposes of Sections 2.14 through 2.17,
         Section 2.19 and Section 10.3, and shall cease to have any obligations
         or any Commitment hereunder, other than to the Agents pursuant to
         Article IX, and the Global Administrative Agent shall promptly notify
         the Accepting Lenders and Borrower of the new Commitments; or

                  (ii) elect to extend the Revolving Commitment Termination Date
         and, prior to or no later than the then scheduled Revolving Commitment
         Termination Date, (A) to replace one or more of the Declining Lenders
         with another lender or lenders reasonably acceptable to the Global
         Administrative Agent (such lenders herein called the "Replacement
         Lenders") and (B) Borrower shall pay in full in immediately available
         funds all Obligations of Borrower owing to any Declining Lenders which
         are not being replaced, as provided in clause (i) above; provided that
         (x) any Replacement Lender shall purchase, and any Declining Lender
         shall sell, such Declining Lender's rights and obligations hereunder
         without recourse or expense to, or warranty by, such Declining Lender
         for a purchase price equal to the aggregate outstanding principal
         amount of the

                                       20
<PAGE>

         Obligations payable to such Declining Lender plus any accrued but
         unpaid interest on such Obligations and accrued but unpaid fees or
         other amounts owing in respect of such Declining Lender's Loans and
         Commitments hereunder, and (y) upon the payment of such amounts
         referred to in clause (x) and the execution of an Assignment and
         Acceptance by such Replacement Lender and such Declining Lender, such
         Replacement Lender shall constitute a Lender hereunder and such
         Declining Lender being so replaced shall no longer constitute a Lender
         (other than for purposes of Sections 2.14 through 2.17, Section 2.19
         and Section 10.3), and shall no longer have any obligations hereunder,
         other than to the Agents pursuant to Article IX; or

                  (iii) elect to revoke and cancel the extension request in such
         Certificate of Extension by giving notice of such revocation and
         cancellation to the Global Administrative Agent (which shall promptly
         notify the Lenders thereof) no later than the tenth (10th) day
         following the date by which each Lender is required, pursuant to clause
         (a) of this Section, to approve or disapprove the requested extension
         of the Revolving Commitment Termination Date, and concomitantly the
         total Commitments.

         If Borrower fails to timely provide the election notice referred to in
this clause (c), Borrower shall be deemed to have revoked and cancelled the
extension request in the Certificate of Extension and to have elected not to
extend the Revolving Commitment Termination Date.

         SECTION 2.7 Interest Elections.

         (a) Each Borrowing initially shall be of the Type specified in the
applicable Borrowing Request (or an ABR Borrowing if no Type is specified) and,
in the case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request (or one month if no Interest Period is
specified). Thereafter, Borrower may elect to convert such Borrowing to a
different Type or to continue such Borrowing and, in the case of a Eurodollar
Borrowing, may elect Interest Periods therefor, all as provided in this Section.
Borrower may, subject to the requirements of Section 2.2(c), elect different
options with respect to different portions of the affected Borrowing, in which
case each such portion shall be allocated ratably among the Lenders holding the
Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing.

         (b) To make an election pursuant to this Section, Borrower shall notify
the Global Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.3 if Borrower were
requesting a Borrowing of the Type resulting from such election to be made on
the effective date of such election. Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Global Administrative Agent of a written Interest Election
Request signed by Borrower.

         (c) Each telephonic and written Interest Election Request shall specify
the following information in compliance with Section 2.2:

                  (i) the Borrowing to which such Interest Election Request
         applies and, if different options are being elected with respect to
         different portions thereof, the portions

                                       21
<PAGE>

         thereof to be allocated to each resulting Borrowing (in which case the
         information to be specified pursuant to clauses (iii) and (iv) below
         shall be specified for each resulting Borrowing);

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

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

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

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

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

         (e) If Borrower fails to deliver a timely Interest Election Request
with respect to a Eurodollar Borrowing prior to the end of the Interest Period
applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the end of such Interest Period such Borrowing shall be converted to an ABR
Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default
has occurred and is continuing and the Global Administrative Agent, at the
request of the Required Lenders, so notifies Borrower, then, so long as an Event
of Default is continuing, (i) no outstanding Borrowing may be converted to or
continued as a Eurodollar Borrowing and (ii) unless repaid and provided the
Indebtedness has not been accelerated pursuant to Section 8.3, each Eurodollar
Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto.

         SECTION 2.8 Termination and Reduction of Commitments.

         (a) The Revolving Commitments shall terminate on the Revolving
Commitment Termination Date. Unless previously terminated, the Term Commitment
shall terminate on the Maturity Date.

         (b) Borrower may at any time terminate, or from time to time reduce,
the Commitments; provided that (i) each reduction of the Commitments shall be in
an amount that is an integral multiple of $1,000,000 and not less than
$5,000,000 and (ii) Borrower shall not terminate or reduce the Commitments if,
after giving effect to any concurrent prepayment of the Loans in accordance with
Section 2.10, the sum of the Credit Exposures would exceed the total
Commitments.

         (c) Borrower shall notify the Global Administrative Agent of any
election to terminate or reduce the Commitments under paragraph (b) of this
Section at least two Business

                                       22
<PAGE>

Days prior to the effective date of such termination or reduction, specifying
such election and the effective date thereof. Promptly following receipt of any
notice, the Global Administrative Agent shall advise the Lenders of the contents
thereof. Each notice delivered by Borrower pursuant to this Section shall be
irrevocable; provided that a notice of termination of the Commitments delivered
by Borrower may state that such notice is conditioned upon the effectiveness of
other credit facilities, in which case such notice may be revoked by Borrower
(by notice to the Global Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction
of the Commitments shall be permanent. Each reduction of the Commitments shall
be made ratably among the Lenders in accordance with their respective
Commitments.

         SECTION 2.9 Repayment of Loans; Evidence of Debt.

         (a) Borrower hereby unconditionally promises to pay to the Global
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Loan on the Maturity Date or, if earlier, the date on which the
Commitment of such Lender relating to such Loan is terminated (except for
termination of the Commitment of the assigning Lender pursuant to Section
10.4(b)).

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

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

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

         (e) Any Lender may request that Loans made by it be evidenced by one or
more promissory notes. In such event, Borrower shall prepare, execute and
deliver to such Lender promissory notes payable to the order of such Lender (or,
if requested by such Lender, to such Lender and its registered assigns and in a
form approved by the Global Administrative Agent). Thereafter, the Loans
evidenced by such promissory notes and interest thereon shall at all times
(including after assignment pursuant to Section 10.4) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if any such promissory note is a registered note, to such payee and
its registered assigns).

                                       23
<PAGE>

         SECTION 2.10 Prepayment of Loans.

         (a) Borrower shall have the right at any time and from time to time to
prepay any Borrowing in whole or in part, subject to prior notice in accordance
with paragraph (b) of this Section.

         (b) Borrower shall notify the Global Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Borrowing, not later than 1:00 p.m., New York City
time, three Business Days before the date of prepayment or (ii) in the case of
prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time,
on the date of prepayment. Each such notice shall be irrevocable and shall
specify the prepayment date and the principal amount of each Borrowing or
portion thereof to be prepaid; provided that, if a notice of prepayment is given
in connection with a conditional notice of termination of the Commitments as
contemplated by Section 2.8, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.8. Promptly
following receipt of any such notice relating to a Borrowing, the Global
Administrative Agent shall advise the Lenders of the contents thereof. Each
partial prepayment of any Borrowing shall be in an amount that would be
permitted in the case of an advance of a Borrowing of the same Type as provided
in Section 2.2. Each prepayment of a Borrowing shall be applied ratably to the
Loans included in the prepaid Borrowing. Prepayments shall be accompanied by
accrued interest to the extent required by Section 2.12 and compensation for
break funding, to the extent required by Section 2.15.

         SECTION 2.11 Fees.

         (a) Borrower agrees to pay to the Global Administrative Agent for the
account of each Lender a facility fee (the "Facility Fee"), which shall accrue
at the Applicable Rate on the daily amount of the Commitment of such Lender
(whether used or unused) during the period from and including the Global
Effective Date to but excluding the earlier to occur of (i) the date on which
such Commitment terminates (except for termination of the Commitment of the
assigning Lender pursuant to Section 10.4(b)) or (ii) the Maturity Date;
provided that, if such Lender continues to have any Credit Exposure after its
Commitment terminates, then such Facility Fee shall continue to accrue on the
daily amount of such Lender's Credit Exposure from and including the date on
which its Commitment terminates to but excluding the date on which such Lender
ceases to have any Credit Exposure. Accrued Facility Fees shall be payable in
arrears on the first day of, April, July and October and the second day of
January of each year and on the date on which the Commitments terminate,
commencing on the first such date to occur after the date hereof; provided that
any Facility Fees accruing after the date on which the Commitments terminate
shall be payable on demand. All Facility Fees shall be computed on the basis of
a year of 365 days (or 366 days in a leap year) and shall be payable for the
actual number of days elapsed (including the first day but excluding the last
day).

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

                                       24
<PAGE>

         (c) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Global Administrative Agent for
distribution, in the case of Facility Fees, to the Lenders. Fees paid shall not
be refundable under any circumstances.

         SECTION 2.12 Interest.

         (a) The Loans comprising each ABR Borrowing shall bear interest on the
daily amount outstanding at the Alternate Base Rate.

         (b) The Loans comprising each Eurodollar Borrowing shall bear interest
on the daily amount outstanding at the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Rate.

         (c) [Intentionally omitted].

         (d) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by Borrower hereunder is not paid
when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the preceding paragraphs
of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Loans as provided in paragraph (a) of this Section.

         (e) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Loans, on the Maturity
Date; provided that (i) interest accrued pursuant to paragraph (d) of this
Section shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Loan, accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment, (iii) in
the event of any conversion of any Eurodollar Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion, and (iv) with respect to any Declining
Lender, accrued interest shall be paid upon the termination of the Commitment of
such Lender.

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

         SECTION 2.13 Alternate Rate of Interest. If prior to the commencement
of any Interest Period for a Eurodollar Borrowing:

                  (i) the Global Administrative Agent determines (which
         determination shall be conclusive absent demonstrable error) that
         adequate and reasonable means do not exist for ascertaining the
         Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest
         Period; or

                                       25
<PAGE>

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

then the Global Administrative Agent shall give notice thereof to Borrower and
the Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Global Administrative Agent notifies Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective,
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing; provided that if the circumstances
giving rise to such notice affect only one Type of Borrowings, then the other
Type of Borrowings shall be permitted.

         SECTION 2.14 Increased Costs.

         (a) If any Change in Law shall:

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

                  (ii) impose on any Lender or the London interbank market any
         other condition affecting this Agreement or Eurodollar Loans made by
         such Lender;

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

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

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section (together with the
calculation thereof) shall be delivered to Borrower and shall be conclusive
absent demonstrable error. Borrower shall pay such Lender the amount shown as
due on any such certificate within 10 days after receipt thereof.

                                       26
<PAGE>

         (d) Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender
notifies Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

         SECTION 2.15 Break Funding Payments. In the event of (a) the payment of
any principal of any Eurodollar Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Loan on the date specified in any notice delivered pursuant hereto
(regardless of whether such notice may be revoked under Section 2.10(b) and is
revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan
other than on the last day of the Interest Period applicable thereto as a result
of a request by Borrower pursuant to either Section 2.6, or Section 2.18 then,
in any such event, Borrower shall compensate each Lender for the loss, cost and
expense attributable to such event. In the case of a Eurodollar Loan, such loss,
cost or expense to any Lender shall be deemed to include an amount determined by
such Lender to be the excess, if any, of (i) the amount of interest which would
have accrued on the principal amount of such Loan had such event not occurred,
at the Adjusted LIBO Rate that would have been applicable to such Loan, for the
period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
for the period that would have been the Interest Period for such Loan), over
(ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive,
together with the calculation thereof, pursuant to this Section shall be
delivered to Borrower and the Global Administrative Agent and shall be
conclusive absent demonstrable error. Borrower shall pay to the Global
Administrative Agent for the account of such Lender the amount shown as due on
any such certificate within 10 days after receipt thereof.

         SECTION 2.16 Taxes.

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

                                       27
<PAGE>

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

         (c) Borrower shall pay the Global Administrative Agent and each Lender,
within 10 days after written demand therefor, the full amount of any Indemnified
Taxes or Other Taxes paid by the Global Administrative Agent or such Lender, as
the case may be, on or with respect to any payment by or on account of any
obligation of Borrower hereunder (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section)
and any penalties, interest and reasonable expenses arising therefrom or with
respect thereto (other than any such penalties or interest arising through the
failure of the Global Administrative Agent or Lender to act as a reasonably
prudent agent or lender, respectively), whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to Borrower by a Lender, or by the Global Administrative
Agent on its own behalf or on behalf of a Lender, shall be conclusive absent
demonstrable error.

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

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

         SECTION 2.17 Payments Generally; Pro Rata Treatment; Sharing of
Set-offs.

         (a) Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest or fees, or of amounts payable under
Section 2.14, 2.15 or 2.16, or otherwise) prior to 1:00 p.m., New York City
time, on the date when due, in immediately available funds, without set-off or
counterclaim. All such payments shall be made to the Global Administrative
Agent, c/o Loan & Agency Services Group, One Chase Manhattan Plaza, 8th Floor,
New York, New York 10081, attention: Lisa Pucciarelli, telephone: (212)
552-7446, facsimile: (212) 552-5777, except that payments pursuant to Sections
2.14, 2.16 and 10.3 shall be made directly to the Persons entitled thereto. The
Global Administrative Agent shall distribute any such payments received by it
for the account of any other Person to the appropriate recipient promptly
following receipt thereof. If any payment hereunder shall be due on a day that
is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

                                       28
<PAGE>

         (b) If at any time insufficient funds are received by and available to
the Global Administrative Agent to pay fully all amounts of principal, interest
and fees then due hereunder, such funds shall be applied (i) first, towards
payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties, and (ii) second, towards payment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties. If insufficient funds are received due to
Borrower's entitlement to withhold amounts on account of Excluded Taxes in
relation to a particular Lender, such insufficiency shall not be subject to this
Section 2.17(b) but shall be withheld from and shall only affect payments made
to such Lender.

         (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are
purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to Borrower or any Subsidiary or Affiliate thereof (as
to which the provisions of this paragraph shall apply). Borrower consents to the
foregoing and agrees, to the extent it may effectively do so under applicable
law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against Borrower rights of set-off and counterclaim
with respect to such participation as fully as if such Lender were a direct
creditor of Borrower in the amount of such participation.

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

         (e) If any Lender shall fail to make any payment required to be made by
it pursuant to Section 2.17(d), then the Global Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Global

                                       29
<PAGE>

Administrative Agent for the account of such Lender to satisfy such Lender's
obligations under such Section until all such unsatisfied obligations are fully
paid.

         SECTION 2.18 Mitigation Obligations; Replacement of Lenders.

         (a) If any Lender requests compensation under Section 2.14, or if
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.14 or 2.16, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

         (b) If any Lender requests compensation under Section 2.14, or if
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16,
or if any Lender defaults in its obligation to fund Loans hereunder, then
Borrower may upon notice to such Lender and the Global Administrative Agent,
require such Lender to assign and delegate, without recourse or expense to, or
warranty by, such Lender (in accordance with and subject to the restrictions
contained in Section 10.4), all its interests, rights and obligations under this
Agreement to an assignee designated by Borrower which meets the requirements of
Section 10.4(b) that shall assume such obligations (which assignee may be
another Lender, if a Lender accepts such assignment); provided that (i) Borrower
shall have received the prior written consent of the Global 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
Loans, accrued interest thereon, accrued fees and all other amounts payable to
it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or Borrower (in the case of all other amounts), (iii)
the assignee and assignor shall have entered into an Assignment and Acceptance,
and (iv) in the case of any such assignment resulting from a claim for
compensation under Section 2.14 or payments required to be made pursuant to
Section 2.16, such assignment will result in a reduction in such compensation or
payments.

         SECTION 2.19 Currency Conversion and Currency Indemnity.

         (a) Payments in Agreed Currency. Borrower shall make payment relative
to any Obligation in the currency (the "Agreed Currency") in which the
Obligation was effected. If any payment is received on account of any Obligation
in any currency (the "Other Currency") other than the Agreed Currency (whether
voluntarily or pursuant to an order or judgment or the enforcement thereof or
the realization of any security or the liquidation of Borrower or otherwise
howsoever), such payment shall constitute a discharge of the liability of
Borrower hereunder and under the other Loan Documents in respect of such
obligation only to the extent of the amount of the Agreed Currency which the
relevant Lender or Agent, as the case may be, is able to purchase with the
amount of the Other Currency received by it on the Business Day next following
such

                                       30
<PAGE>

receipt in accordance with its normal procedures and after deducting any premium
and costs of exchange.

         (b) Conversion of Agreed Currency into Judgment Currency. If, for the
purpose of obtaining or enforcing judgment in any court in any jurisdiction, it
becomes necessary to convert into a particular currency (the "Judgment
Currency") any amount due in the Agreed Currency then the conversion shall be
made on the basis of the rate of exchange prevailing on the next Business Day
following the date such judgment is given and in any event Borrower shall be
obligated to pay the Agents and the Lenders any deficiency in accordance with
Section 2.19(c). For the foregoing purposes "rate of exchange" means the rate at
which the relevant Lender or Agent, as applicable, in accordance with its normal
banking procedures is able on the relevant date to purchase the Agreed Currency
with the Judgment Currency after deducting any premium and costs of exchange.

         (c) Circumstances Giving Rise to Indemnity. If (i) any Lender or any
Agent receives any payment or payments on account of the liability of Borrower
hereunder pursuant to any judgment or order in any Other Currency, and (ii) the
amount of the Agreed Currency which the relevant Lender or Agent, as applicable,
is able to purchase on the Business Day next following such receipt with the
proceeds of such payment or payments in accordance with its normal procedures
and after deducting any premiums and costs of exchange is less than the amount
of the Agreed Currency due in respect of such obligations immediately prior to
such judgment or order, then Borrower on demand shall, and Borrower hereby
agrees to, indemnify and save the Lenders and the Agents harmless from and
against any loss, cost or expense arising out of or in connection with such
deficiency.

         (d) Indemnity Separate Obligation. The agreement of indemnity provided
for in Section 2.19(c) shall constitute an obligation separate and independent
from all other obligations contained in this Agreement, shall give rise to a
separate and independent cause of action, shall apply irrespective of any
indulgence granted by the Lenders or Agents or any of them from time to time,
and shall continue in full force and effect notwithstanding any judgment or
order for a liquidated sum in respect of an amount due hereunder or under any
judgment or order.

         SECTION 2.20 Additional Borrowers.

         (a) A Person which is a Restricted Subsidiary which is a resident of,
and domiciled in, the United States may become an Additional Borrower with
respect hereto, and shall be bound by and entitled to the benefits and
obligations of this Agreement as a Borrower hereunder to the same extent as any
other Borrower, upon the fulfillment of the following conditions:

                  (i) Resolutions and Officers' Certificates. Such Person shall
         deliver all the items identified in Section 4.1(a) with respect to such
         Person.

                  (ii) Certificate. An Authorized Officer of each Borrower shall
         have delivered to the Global Administrative Agent a certificate stating
         that such Person is a Restricted Subsidiary of the Parent which is
         resident of, and domiciled in, the United States.

                  (iii) No Default. No Default or Event of Default shall have
         occurred and be continuing.

                                       31
<PAGE>

                  (iv) Representations and Warranties. The representations and
         warranties in Article III hereto are true and correct with respect to
         such Person, mutatis mutandis, as of the date such Person executes the
         Additional Borrower Counterpart described in clause (v) below.

                  (v) Additional Borrower Counterpart. Such Person shall execute
         an Additional Borrower Counterpart to this Agreement, substantially in
         the form of Exhibit F (the "Additional Borrower Counterpart") or such
         other agreement in form and substance satisfactory to the Global
         Administrative Agent.

                  (vi) Opinions of Counsel. The Global Administrative Agent
         shall have received legal opinions, dated as of the date such Person
         executes the Additional Borrower Counterpart described above, addressed
         to the Agents and the Lenders, having substantially the same coverage
         as those opinions attached hereto as Exhibits A and B and in form and
         substance acceptable to the Global Administrative Agent, in its
         reasonable discretion.

                  (vii) Approval. The Global Administrative Agent shall have
         approved the addition of such Person as an Additional Borrower, such
         approval not to be unreasonably withheld.

         (b) Upon fulfillment of the conditions in this Section 2.20(a), the
Global Administrative Agent will promptly notify each Lender of the date that
such Person becomes an Additional Borrower hereunder.

                                   ARTICLE III

                         Representations and Warranties

         In order to induce the Lenders and the Agents to enter into this
Agreement and the Lenders to make Loans hereunder, Borrower represents and
warrants unto the Agents and each Lender as set forth in this Article III.

         SECTION 3.1 Organization. Borrower is a corporation, and each of its
Subsidiaries is a corporation or other legal entity, in either case duly
incorporated or otherwise properly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation or organization and
has all requisite authority, permits and approvals, and is in good standing to
conduct its business in each jurisdiction in which its business is conducted
where the failure to so qualify would have a Material Adverse Effect.

         SECTION 3.2 Authorization and Validity. The execution, delivery and
performance by Borrower of this Agreement and each other Loan Document executed
or to be executed by it, are within Borrower's corporate powers, have been duly
authorized by all necessary corporate action on behalf of it, and do not (a)
contravene Borrower's articles of incorporation or other organizational
documents, as the case may be; (b) contravene any material contractual
restriction, law or governmental regulation or court decree or order binding on
or affecting Borrower or any Subsidiary; or (c) result in, or require the
creation or imposition of, any Lien, not permitted by Section 7.1, on any of
Borrower's or any Subsidiary's properties.

                                       32
<PAGE>

This Agreement constitutes, and each other Loan Document executed by Borrower
will, on the due execution and delivery thereof, constitute, the legal, valid
and binding obligations of Borrower enforceable in accordance with their
respective terms subject as to enforcement only to bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditor rights generally and to general principles of equity.

         SECTION 3.3 Government Approval and Regulation. No authorization or
approval or other action by, and no notice to or filing with, any governmental
authority or regulatory body or other Person is required for the due execution,
delivery or performance by Borrower of this Agreement or any other Loan
Document. Neither Borrower nor any of its Subsidiaries is an "investment
company," within the meaning of the Investment Company Act of 1940, as amended,
or 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," within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

         SECTION 3.4 Pension and Welfare Plans. During the
twelve-consecutive-month period prior to the date of the execution and delivery
of this Agreement and prior to the date of any Borrowing hereunder, no steps
have been taken to terminate any Pension Plan, and no contribution failure has
occurred with respect to any Pension Plan sufficient to give rise to a lien
under Section 302(f) of ERISA. No condition exists or event or transaction has
occurred with respect to any Pension Plan which would result in the incurrence
by Borrower or any member of the Controlled Group of any liability, fine or
penalty in excess of $25,000,000. Neither Borrower nor any member of the
Controlled Group has any contingent liability with respect to any
post-retirement benefit under a Welfare Plan, other than liability for
continuation coverage described in Part 6 of Title I of ERISA.

         SECTION 3.5 Regulation U. Borrower is not engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock, and no
proceeds of any Loans will be used for a purpose which violates, or would be
inconsistent with, Regulation U. Terms for which meanings are provided in
Regulations U are used in this Section with such meanings.

         SECTION 3.6 Taxes. Borrower and each of its Subsidiaries has to the
best knowledge of Borrower after due investigation filed all tax returns and
reports required by law to have been filed by it and has paid all taxes and
governmental charges thereby shown to be owing, except any such taxes or charges
which are being contested in good faith by appropriate proceedings and for which
adequate reserves in accordance with GAAP shall have been set aside on its books
or which the failure to file or pay could not reasonably be expected to have a
Material Adverse Effect.

         SECTION 3.7 Subsidiaries; Restricted Subsidiaries. Schedule 3.7 hereto
contains an accurate list of all of the presently existing Subsidiaries,
including, without limitation, Restricted Subsidiaries, of Borrower as of the
date of this Agreement, setting forth their respective jurisdictions of
incorporation or organization and the percentage of their respective capital
stock or, the revenue share attributable to the general and limited partnership
interests, as the case may be, owned by Borrower or other Subsidiaries. All of
the issued and outstanding

                                       33
<PAGE>

shares of capital stock of such Subsidiaries which are corporations have been
duly authorized and issued and are fully paid and non-assessable.

                                   ARTICLE IV

                                   Conditions

         SECTION 4.1 Effectiveness. This Agreement shall become effective upon
the prior or concurrent satisfaction of each of the conditions precedent set
forth in this Section 4.1.

         (a)      Resolutions and Officers Certificates. The Global
                  Administrative Agent shall have received from Borrower a
                  certificate, dated the Global Effective Date, of the Secretary
                  or Assistant Secretary of Borrower as to (i) resolutions of
                  its governing board, then in full force and effect authorizing
                  the execution, delivery and performance of this Agreement and
                  each other Loan Document to be executed by it; (ii) the
                  incumbency and signatures of those of its officers authorized
                  to act with respect to this Agreement and each other Loan
                  Document executed by it; and (iii) its articles of
                  incorporation and bylaws; upon which certificates each Lender
                  may conclusively rely until it shall have received a further
                  certificate of an authorized officer of Borrower canceling or
                  amending such prior certificate.

         (b)      Existing Facilities. The Global Administrative Agent shall
                  have received a certificate, signed by an Authorized Officer
                  of Borrower, stating that Borrower or its Subsidiaries have
                  repaid in full and terminated the Existing Global Credit
                  Facilities concurrently with the effectiveness of the Combined
                  Credit Agreements.

         (c)      Opinions of Counsel. The Global Administrative Agent shall
                  have received opinions, dated the Global Effective Date,
                  addressed to the Global Administrative Agent, the other Agents
                  and all Lenders, from (i) Jeffrey B. King, Esq., Corporate
                  Counsel and Assistant Secretary of Borrower, in substantially
                  the form attached hereto as Exhibit A, and (ii) Chamberlain,
                  Hrdlicka, White, Williams & Martin, counsel to Borrower, in
                  substantially the form attached hereto as Exhibit B.

         (d)      Closing Fees and Expenses. The Global Administrative Agent
                  shall have received for its own account, or for the account of
                  each Lender and other Agent, as the case may be, all fees,
                  costs and expenses due and payable pursuant hereto.

         (e)      Financial Statements. The Global Administrative Agent shall
                  have received a certificate, signed by an Authorized Officer
                  of Borrower, stating that the audited consolidated financial
                  statements of Borrower and its Subsidiaries for fiscal year
                  2001 (the "2001 Financials") fairly present Borrower's
                  financial condition and results of operations and that prior
                  to the Global Effective Date no material adverse change in the
                  condition or operations of Borrower and its Subsidiaries,
                  taken as a whole, from that reflected in the 2001 Financials
                  has occurred and is continuing.

         (f)      Environmental Warranties. In the ordinary course of its
                  business, Borrower conducts an ongoing review of the effect of
                  existing Environmental Laws on the

                                       34
<PAGE>

                  business, operations and properties of Borrower and its
                  Subsidiaries, in the course of which it attempts to identify
                  and evaluate associated liabilities and costs (including,
                  without limitation, any capital or operating expenditures
                  required for clean-up or closure of properties presently or
                  previously owned, any capital or operating expenditures
                  required to achieve or maintain compliance with environmental
                  protection standards imposed by law or as a condition of any
                  license, permit or contract, any related constraints on
                  operating activities, including any periodic or permanent
                  shutdown of any facility or reduction in the level of or
                  change in the nature of operations conducted thereat and any
                  actual or potential liabilities to third parties, including
                  employees, and any related costs and expenses). On the basis
                  of this review, the Global Administrative Agent shall have
                  received a certificate, signed by an Authorized Officer of
                  Borrower, stating that after such review Borrower has
                  reasonably concluded that existing Environmental Laws are
                  unlikely to have a Material Adverse Effect, or that Borrower
                  has established adequate reserves in respect of any required
                  clean-up.

         (g)      Global Effectiveness Notice. The Global Administrative Agent
                  shall have received the Global Effectiveness Notice.

                  Canadian Loan Documents and (iii) U.S. Credit Agreement and
                  the other U.S. Loan Documents.

         (i)      Litigation. The Global Administrative Agent shall have
                  received a certificate, signed by an Authorized Officer of
                  Borrower, stating that no litigation, arbitration,
                  governmental proceeding, Tax claim, dispute or administrative
                  or other proceeding shall be pending or, to the knowledge of
                  Borrower, threatened against Borrower or any of its
                  Subsidiaries which could reasonably be expected to have a
                  Material Adverse Effect or which purports to affect the
                  legality, validity or enforceability of this Agreement or any
                  other Loan Document.

         (j)      Other Documents. The Global Administrative Agent shall have
                  received such other instruments and documents as any of the
                  Agents or their counsel may have reasonably requested.

The Global Administrative Agent shall notify Borrower, the other Agents and the
Lenders of the Global Effective Date, and such notice shall be conclusive and
binding. Notwithstanding the foregoing, the obligations of the Lenders to make
Loans hereunder shall not become effective unless each of the foregoing
conditions is satisfied (or waived pursuant to Section 10.2) at or prior to 3:00
p.m., New York City time, on July 31, 2002 (and, in the event such conditions

Agreement on the occasion of any Borrowing shall be subject to the satisfaction
of each of the conditions precedent set forth in this Section 4.2.

         (a)      Compliance with Warranties and No Default. Both before and
                  after giving effect to any Borrowing, the following statements
                  shall be true and correct: (1) the representations and
                  warranties set forth in Article III shall be true and correct
                  with the same effect as if then made (unless stated to relate

                  and warranties shall be true and correct as of such earlier
                  date); and (b) no Default or Event of Default shall have then
                  occurred and be continuing.

         (b)      Borrowings. The Global Administrative Agent shall have

         (b)      within 45 days after the end of each of the first three fiscal

                  action with respect to a Pension Plan which would reasonably

each of its Subsidiaries to, maintain, preserve, protect and keep valid title
to, or valid leasehold interest in, all of its properties and assets, real and

matters with its officers and to examine (and, at the expense of the Global
Administrative Agent or such other Agent or Lender or, if a Default or Event of
Default has occurred and is continuing, at the expense of Borrower, photocopy
extracts from) any of its books or other records.

         SECTION 5.6 Minimum Book Value for Assets of Borrower and its
Restricted Subsidiaries. Apache shall maintain an aggregate book value for
assets of Apache and its Restricted Subsidiaries (without duplication and

$2,000,000,000 less (ii) the aggregate amount of any non-cash write downs (other

Subsidiary; provided that, if as of the end of any fiscal quarter Apache is not
in compliance with this Section, Apache, for a period of 30 days following the
delivery of the financial statements for such fiscal quarter, shall be entitled
to cure such non-compliance by delivering a notice to the Global Administrative
Agent designating certain Unrestricted Subsidiaries as Restricted Subsidiaries
for the purposes of this Agreement at which time the Global Administrative Agent
shall redetermine compliance with this Section using such newly-designated
Restricted Subsidiaries in such redetermination.

Subsidiary to, use the proceeds of the Loans (i) to refinance existing
Indebtedness of Borrower and its Subsidiaries, (ii) for Borrower's and its

                  made or deemed to be made hereunder or in any other Loan
                  Document or any other writing or certificate furnished by or
                  on behalf of Borrower to the Global Administrative Agent, any
                  other Agent or any Lender for the purposes of or in connection
                  with this Agreement or any such other Loan Document is or
                  shall be false or misleading when made in any material

                  default in the due performance and observance of any of its

         (d)      Non-Performance of Other Covenants and Obligations. Borrower
                  shall default in the due performance and observance of any

<PAGE>

                  period of 30 days after notice thereof shall have been given
                  to Borrower by the Global Administrative Agent or the Required
                  Lenders.

         (e)      Default on Other Indebtedness. A default shall occur in the
                  payment when due (subject to any applicable grace period),
                  whether by acceleration or otherwise, of any direct payment
                  obligation of Borrower or any of its Restricted Subsidiaries
                  in any amount in excess of $25,000,000.

         (f)      Pension Plans. Any of the following events shall occur with
                  respect to any Pension Plan: (a) the institution of any steps
                  by Borrower, any member of its Controlled Group or any other
                  Person to terminate a Pension Plan if, as a result of such
                  termination, Borrower or any such member could be required to
                  make a contribution to such Pension Plan, or would reasonably
                  expect to incur a liability or obligation to such Pension
                  Plan, in excess of $25,000,000; or (b) a contribution failure
                  occurs with respect to any Pension Plan sufficient to give
                  rise to a lien under Section 302(f) of ERISA.

         (g)      Bankruptcy and Insolvency. Borrower or any of its Restricted
                  Subsidiaries shall (a) become insolvent or generally fail to
                  pay, or admit in writing its inability or unwillingness to
                  generally pay, debts as they become due; (b) apply for,
                  consent to, or acquiesce in, the appointment of a trustee,
                  receiver, sequestrator or other custodian for Borrower, or any
                  of its Restricted Subsidiaries, or any substantial part of the
                  property of any thereof, or make a general assignment for the
                  benefit of creditors; (c) in the absence of such application,
                  consent or acquiescence, permit or suffer to exist the
                  appointment of a trustee, receiver, sequestrator or other
                  custodian for Borrower, or any of its Restricted Subsidiaries,
                  or for a substantial part of the property of any thereof, and
                  such trustee, receiver, sequestrator or other custodian shall
                  not be discharged within 60 days, provided that Borrower and
                  each Restricted Subsidiary hereby expressly authorizes the
                  Global Administrative Agent, each other Agent and each Lender
                  to appear in any court conducting any relevant proceeding
                  during such 60-day period to preserve, protect and defend
                  their rights under the Loan Documents; (d) permit or suffer to
                  exist the commencement of any bankruptcy, reorganization, debt
                  arrangement or other case or proceeding under any bankruptcy
                  or insolvency law, or any dissolution, winding up or
                  liquidation proceeding, in respect of Borrower or any of its
                  Restricted Subsidiaries, and, if any such case or proceeding
                  is not commenced by Borrower or such Restricted Subsidiary,
                  such case or proceeding shall be consented to or acquiesced in
                  by Borrower or such Restricted Subsidiary or shall result in
                  the entry of an order for relief or shall remain for 60 days
                  undismissed, provided that Borrower and each Restricted
                  Subsidiary hereby expressly authorizes the Global
                  Administrative Agent and each Lender to appear in any court
                  conducting any such case or proceeding during such 60-day
                  period to preserve, protect and defend their rights under the
                  Loan Documents; or (e) take any corporate or partnership
                  action authorizing, or in furtherance of, any of the
                  foregoing.

         (h)      Judgments. Any judgment or order for the payment of money in
                  an amount of $25,000,000 or more in excess of valid and
                  collectible insurance in respect thereof or in excess of an
                  indemnity with respect thereto reasonably acceptable to the
                  Required Lenders shall be rendered against Borrower or any of
                  its Restricted Subsidiaries and either (a) enforcement
                  proceedings shall have been commenced by any creditor upon
                  such judgment or order, or (b) such judgment shall have become
                  final and non-appealable and shall have remained outstanding
                  for a period of 60 consecutive days.

         (i)      Change in Control. Any Person or group of Persons (within the
                  meaning of Section 13 or 14 of the Securities Exchange Act)
                  shall acquire beneficial ownership (within the meaning of Rule
                  13d-3 promulgated by the Securities and Exchange Commission
                  under the Securities Exchange Act) of 33 1/3% or more of the
                  outstanding shares of common stock of Borrower.

         (j)      Event of Default under other Combined Loan Documents. Any
                  "Event of Default" as defined in the Australian Loan
                  Documents, the Canadian Loan Documents or the U.S. Loan
                  Documents shall occur; provided that the occurrence of a
                  "Default" as defined in the Australian Loan Documents, the
                  Canadian Loan Documents or the U.S. Loan Documents shall
                  constitute a Default under this Agreement; provided further
                  that if such "Default" is cured or waived under the Australian
                  Loan Documents, the Canadian Loan Documents or the U.S. Loan
                  Documents, as applicable, then such "Default" shall no longer
                  constitute a Default under this Agreement.

         SECTION 8.2 Action if Bankruptcy. If any Event of Default described in
Section 8.1(g) shall occur, the Commitments (if not theretofore terminated)
shall automatically terminate and the outstanding principal amount of all
outstanding Loans and all other obligations hereunder shall automatically be and
become immediately due and payable, without notice or demand.

         SECTION 8.3 Action if Other Event of Default. If any Event of Default
(other than any Event of Default described in Section 8.2) shall occur for any
reason, whether voluntary or involuntary, and be continuing, the Global
Administrative Agent, upon the direction of the Required Lenders, shall by
notice to Borrower declare all of the outstanding principal amount of the Loans
and all other obligations hereunder to be due and payable and the Commitments
(if not theretofore terminated) to be terminated, whereupon the full unpaid
amount of such Loans and other obligations shall be and become immediately due
and payable, without further notice, demand or presentment, and the Commitments
shall terminate.

                                   ARTICLE IX

                                     Agents

         Each of the Lenders hereby irrevocably appoints JPMorgan Chase Bank as
Global Administrative Agent, Bank of America, N.A. as Global Syndication Agent,
Citibank, N.A. as Global Documentation Agent, Bank of America, N.A., and BNP
Paribas as 364-Day Co-

                                       43
<PAGE>

Syndication Agents, and Deutsche Bank AG New York Branch and Societe Generale as
364-Day Co-Documentation Agents, and authorizes each such Agent to take such
actions on its behalf and to exercise such powers as are delegated to such Agent
by the terms hereof, together with such actions and powers as are reasonably
incidental thereto.

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

         The Agents shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing,
(a) the Agents shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing, (b) each Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that such Agent is required to exercise in writing by the
Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 10.2), and (c) except
as expressly set forth herein, the Agents shall not have any duty to disclose,
and shall not be liable for the failure to disclose, any information relating to
Borrower or any of its Subsidiaries that is communicated to or obtained by the
bank serving as such Agent or any of its Affiliates in any capacity. Each Agent
shall not be liable for any action taken or not taken by it with the consent or
at the request of the Required Lenders (or such other number or percentage of
the Lenders as shall be necessary under the circumstances as provided in Section
10.2) or in the absence of its own gross negligence or willful misconduct. Each
Agent shall be deemed not to have knowledge of any Default unless and until
written notice thereof is given to such Agent by Borrower or a Lender, and such
Agent shall not be responsible for or have any duty to ascertain or inquire into
(i) any statement, warranty or representation made in or in connection with this
Agreement, (ii) the contents of any certificate, report or other document
delivered hereunder or in connection herewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm receipt of items expressly required to be delivered to such
Agent.

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

                                       44
<PAGE>

         Any Agent may perform any and all its duties and exercise its rights
and powers by or through any one or more sub-agents appointed by such Agent. Any
Agent and any such sub-agent may perform any and all its duties and exercise its
rights and powers through their respective Related Parties. The exculpatory
provisions of the preceding paragraphs shall apply to any such sub-agent and to
the Related Parties of such Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as an Agent.

         Subject to the appointment and acceptance of a successor Global
Administrative Agent as provided in this paragraph, the Global Administrative
Agent may resign at any time by notifying the Lenders and Borrower. Upon any
such resignation, Borrower shall have the right, in consultation with the
Combined Required Lenders, to appoint one of the Lenders as a successor. If no
successor shall have been so appointed by Borrower and shall have accepted such
appointment within 30 days after the retiring Global Administrative Agent gives
notice of its resignation, then the retiring Global Administrative Agent may, on
behalf of the Lenders, appoint a successor Global Administrative Agent which
shall be a bank with an office in New York, New York, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Global Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Global
Administrative Agent, and the retiring Global Administrative Agent shall be
discharged from its duties and obligations hereunder. The fees payable by
Borrower to a successor Global Administrative Agent shall be the same as those
payable to its predecessor unless otherwise agreed between Borrower and such
successor. After the Global Administrative Agent's resignation hereunder, the
provisions of this Article and Section 10.3 shall continue in effect for the
benefit of such retiring Global Administrative Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as Global Administrative Agent.

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

         (c) if to any other Lender, to it at its address (or telecopy number)
provided to the Global Administrative Agent and Borrower or as set forth in its
Administrative Questionnaire.

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

         SECTION 10.2 Waivers; Amendments.

         (a) No failure or delay by the Global Administrative Agent or any
Lender in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Global Administrative Agent and
the Lenders hereunder are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the Global
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

         (b) Any of the Combined Loan Documents or any provision thereof may be
waived, amended or modified pursuant to an agreement or agreements in writing
entered into by Borrower and the Combined Required Lenders or by Borrower and
the Global Administrative Agent with the consent of the Combined Required
Lenders; provided that the same waiver, amendment or modification is requested
by Borrower in connection with each of the Combined Credit Agreements; and
provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of (i) the Lenders described in the first proviso of
Section 10.2(c) without the prior written consent of each Lender affected
thereby and (ii) the Global Administrative Agent without the prior written
consent of the Global Administrative Agent.

         (c) Except as provided for in Section 10.2(b) above, neither this
Agreement nor any other Loan Document nor any provision hereof or thereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by Borrower and the Required Lenders or by Borrower and the
Global Administrative Agent with the consent of the Required Lenders; provided
that no such agreement shall (i) increase the Commitment of any Lender or the
Commitments without the written consent of such Lender or each Lender,
respectively, (ii) reduce the principal amount of any Loan or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment of the principal amount of any Loan, or any interest thereon, or any
fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without
the written consent of each Lender affected thereby, (iv) change Section 2.17(b)
or (c) in a manner

                                       47
<PAGE>

that would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, or (v) change any of the provisions of this
Section or the definition of "Required Lenders", "Combined Required Lenders" or
any other provision hereof or thereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights hereunder or thereunder or
make any determination or grant any consent hereunder or thereunder, without the
written consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Global
Administrative Agent hereunder or thereunder without the prior written consent
of the Global Administrative Agent.

         SECTION 10.3 Expenses; Indemnity; Damage Waiver.

         (a) Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Agents and their Affiliates, including the reasonable fees,
charges and disbursements of counsel for the Agents, in connection with the
syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement or any amendments, modifications or waivers of
the provisions hereof (whether or not the transactions contemplated hereby or
thereby shall be consummated) and (ii) all reasonable out-of-pocket expenses
incurred by the Agents or any Lender, including the fees, charges and
disbursements of any counsel for the Agents or any Lender, in connection with
the enforcement or protection of its rights in connection with this Agreement,
including its rights under this Section, or in connection with the Loans made
hereunder, including all such out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or this
Agreement.

         (b) Borrower shall indemnify the Agents and each Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the
reasonable fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the consummation of the
Transactions or any other transactions contemplated hereby, (ii) any Loan or the
actual or proposed use of the proceeds therefrom, (iii) any actual or alleged
presence or release of Hazardous Materials on or from any property owned or
operated by Borrower or any of its Subsidiaries, or any Environmental Liability
related in any way to Borrower or any of its Subsidiaries, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (i) resulted from the
gross negligence or willful misconduct of such Indemnitee or (ii) arise in
connection with any issue in litigation commenced by Borrower or any of its
Subsidiaries against any Indemnitee for which a final judgment is entered in
favor of Borrower or any of its Subsidiaries against such Indemnitee.

         (c) To the extent that Borrower fails to pay any amount required to be
paid by it to the Global Administrative Agent under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Global Administrative Agent,
such Lender's Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is

                                       48
<PAGE>

sought) of such unpaid amount; provided that the unreimbursed expense or
indemnified loss, claim, damage, liability or related expense, as the case may
be, was incurred by or asserted against the Global Administrative Agent.

         (d) To the extent permitted by applicable law, Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions or any Loan or the use of the proceeds thereof, except for any such
claim arising from such Indemnitee's gross negligence or willful misconduct.

         (e) All amounts due under this Section shall be payable not later than
thirty (30) days after written demand therefor.

         SECTION 10.4 Successors and Assigns.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that Borrower may not assign or otherwise transfer any
of its rights or obligations hereunder without the prior written consent of each
Lender (and any attempted assignment or transfer by Borrower without such
consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Related Parties of each of the Global
Administrative Agent and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

         (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans at the time owing to it); provided that (i) except
in the case of an assignment to a Lender or an Affiliate of a Lender, each of
Apache and the Global Administrative Agent must give their prior written consent
to such assignment (which consent shall not be unreasonably withheld), (ii)
except in the case of an assignment to a Lender or an Affiliate of a Lender or
an assignment of the entire remaining amount of the assigning Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Global Administrative Agent)
shall be in increments of $1,000,000 and not less than $10,000,000 unless each
of Borrower and the Global Administrative Agent otherwise consent, (iii) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender's rights and obligations under this Agreement, (iv) the
parties to each assignment shall execute and deliver to the Global
Administrative Agent an Assignment and Acceptance, together with a processing
and recordation fee of $3,500, and (v) the assignee, if it shall not be a
Lender, shall deliver to the Global Administrative Agent an Administrative
Questionnaire; and provided further that any consent of Apache otherwise
required under this paragraph shall not be required if an Event of Default under
Section 8.1 has occurred and is continuing. Subject to acceptance and recording
thereof pursuant to paragraph (d) of this Section, from and after the effective
date specified in each Assignment and Acceptance the assignee thereunder shall
be a party hereto and, to the extent of the interest assigned by such Assignment
and Acceptance, have the rights

                                       49
<PAGE>

and obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 2.14,
2.15, 2.16, 2.17, 2.19 and 10.3). Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.

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

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

         (e) Any Lender may, without the consent of Borrower or the Global
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (i) such Lender's obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) Borrower,
the Global 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, and (iv) if such Participant is not a Lender
or an Affiliate of a Lender, such Lender shall have given notice to Borrower of
the name of the Participant and the amount of such participation. Any agreement
or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement
and to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 10.2(c) that
affects such Participant. Subject to paragraph (f) of this Section, Borrower
agrees that each

                                       50
<PAGE>

Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16 to
the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.8 as
though it were a Lender, provided such Participant agrees to be subject to
Section 2.17(c) as though it were a Lender.

         (f) A Participant shall not be entitled to receive any greater payment
under Section 2.14, 2.15 or 2.16 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless Borrower shall expressly agree otherwise in writing. A Participant that
would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 2.16 unless Borrower is notified of the participation sold
to such Participant and such Participant agrees, for the benefit of Borrower, to
comply with Section 2.16(e) as though it were a Lender.

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

         SECTION 10.5 Survival. All covenants, agreements, representations and
warranties made by Borrower herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement shall be considered
to have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Loans, regardless
of any investigation made by any such other party or on its behalf and
notwithstanding that the Global Administrative Agent or any Lender may have had
notice or knowledge of any Default or incorrect representation or warranty at
the time any credit is extended hereunder, and shall continue in full force and
effect as long as the principal of or any accrued interest on any Loan or any
fee or any other amount payable under this Agreement is outstanding and unpaid
and so long as the Commitments have not expired or terminated. The provisions of
Sections 2.14, 2.15, 2.16, 2.17, 2.19 and 10.3 and Article IX shall survive and
remain in full force and effect regardless of the consummation of the
transactions contemplated hereby, the repayment of the Loans, the expiration or
termination of the Commitments or the termination of this Agreement or any
provision hereof.

         SECTION 10.6 Counterparts; Integration; Effectiveness. This Agreement
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Global
Administrative Agent constitute the entire contract among the parties relating
to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.1, this Agreement shall become effective when it shall
have been executed by the Global Administrative Agent and when the Global
Administrative Agent shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and
thereafter shall be

                                       51
<PAGE>

binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

         SECTION 10.7 Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

         SECTION 10.8 Right of Setoff. If an Event of Default shall have
occurred and be continuing and the Obligations of Borrower shall have been
accelerated, each Lender and each of its Affiliates is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other obligations at any time owing by such
Lender or Affiliate to or for the credit or the account of any Borrower against
any of and all the obligations of each Borrower now or hereafter existing under
this Agreement held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement and although such obligations
may be unmatured. The rights of each Lender under this Section are in addition
to other rights and remedies (including other rights of setoff) which such
Lender may have.

         SECTION 10.9 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

         (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN THOSE
CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

         (b) BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF
AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE SUPREME COURT OF THE
STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT
COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY
THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE
PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN
RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW
YORK STATE OR, TO THE EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT. EACH OF
THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING
SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT SHALL
AFFECT ANY RIGHT THAT THE AGENTS OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY

                                       52
<PAGE>

ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AGAINST BORROWER OR ITS
PROPERTIES IN THE COURTS OF ANY JURISDICTION.

         (c) BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
FULLEST EXTENT IT MAY LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY COURT REFERRED TO IN
PARAGRAPH (b) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE OF AN INCONVENIENT
FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

         (d) EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF
PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR
WITHOUT THE STATE OF NEW YORK. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT
OF ANY PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW.

         SECTION 10.10 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

         SECTION 10.11 Confidentiality. Each of the Agents and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory or self-regulatory authority, (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section, to any assignee of
or Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (g) with the consent of Borrower or
(h) to the extent such Information (A) becomes publicly available other than as
a result of a breach of this Section by any Person or (B) becomes available to
any Agent or any Lender on a nonconfidential basis from a source other than
Borrower or any Person obligated to maintain the confidentiality of such
Information. Prior to disclosing any Information under clause (c) above, the
Agent or Lender required or asked to make such disclosure shall make a good
faith effort to give Borrower prior notice of such proposed disclosure to permit
Borrower to attempt to obtain a protective order or other appropriate injunctive
relief. For the purposes of this Section, "Information" means all information
received from Borrower relating to Borrower or its business, other than any
publicly available information and such information that is available to any
Agent or any Lender on a nonconfidential basis prior to disclosure by Borrower;
provided that, in the case of information received from Borrower after the date
hereof, such information is clearly identified at the time of

                                       53
<PAGE>

delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

         SECTION 10.12 Interest Rate Limitation. It is the intention of the
parties hereto to conform strictly to applicable interest, usury and criminal
laws and, anything herein to the contrary notwithstanding, the obligations of
Borrower to a Lender or any Agent under this Agreement shall be subject to the
limitation that payments of interest shall not be required to the extent that
receipt thereof would be contrary to provisions of law applicable to such Lender
or Agent limiting rates of interest which may be charged or collected by such
Lender or Agent. Accordingly, if the transactions contemplated hereby would be
illegal, unenforceable, usurious or criminal under laws applicable to a Lender
or Agent (including the laws of any jurisdiction whose laws may be mandatorily
applicable to such Lender or Agent notwithstanding anything to the contrary in
this Agreement or any other Loan Document but subject to Section 2.12 hereof)
then, in that event, notwithstanding anything to the contrary in this Agreement
or any other Loan Document, it is agreed as follows:

                  (i) the provisions of this Section shall govern and control;

                  (ii) the aggregate of all consideration which constitutes
         interest under applicable law that is contracted for, taken, reserved,
         charged or received under this Agreement, or under any of the other
         aforesaid agreements or otherwise in connection with this Agreement by
         such Lender or Agent shall under no circumstances exceed the maximum
         amount of interest allowed by applicable law (such maximum lawful
         interest rate, if any, with respect to each Lender and the Agent herein
         called the "Highest Lawful Rate"), and any excess shall be cancelled
         automatically and if theretofore paid shall be credited to Borrower by
         such Lender or Agent (or, if such consideration shall have been paid in
         full, such excess refunded to Borrower);

                  (iii) all sums paid, or agreed to be paid, to such Lender or
         Agent for the use, forbearance and detention of the indebtedness of
         Borrower to such Lender or Agent hereunder or under any Loan Document
         shall, to the extent permitted by laws applicable to such Lender or
         Agent, as the case may be, be amortized, prorated, allocated and spread
         throughout the full term of such indebtedness until payment in full so
         that the actual rate of interest is uniform throughout the full term
         thereof;

                  (iv) if at any time the interest provided pursuant to this
         Section or any other clause of this Agreement or any other Loan
         Document, together with any other fees or compensation payable pursuant
         to this Agreement or any other Loan Document and deemed interest under
         laws applicable to such Lender or Agent, exceeds that amount which
         would have accrued at the Highest Lawful Rate, the amount of interest
         and any such fees or compensation to accrue to such Lender or Agent
         pursuant to this Agreement shall be limited, notwithstanding anything
         to the contrary in this Agreement or any other Loan Document, to that
         amount which would have accrued at the Highest Lawful Rate, but any
         subsequent reductions, as applicable, shall not reduce the interest to
         accrue to such Lender or Agent pursuant to this Agreement below the
         Highest Lawful Rate until

                                       54
<PAGE>

         the total amount of interest accrued pursuant to this Agreement or such
         other Loan Document, as the case may be, and such fees or compensation
         deemed to be interest equals the amount of interest which would have
         accrued to such Lender or Agent if a varying rate per annum equal to
         the interest provided pursuant to any other relevant Section hereof
         (other than this Section), as applicable, had at all times been in
         effect, plus the amount of fees which would have been received but for
         the effect of this Section; and

                  (v) with the intent that the rate of interest herein shall at
         all times be lawful, and if the receipt of any funds owing hereunder or
         under any other agreement related hereto (including any of the other
         Loan Documents) by such Lender or Agent would cause such Lender to
         charge Borrower a criminal rate of interest, the Lenders and the Agents
         agree that they will not require the payment or receipt thereof or a
         portion thereof which would cause a criminal rate of interest to be
         charged by such Lender or Agent, as applicable, and if received such
         affected Lender or Agent will return such funds to Borrower so that the
         rate of interest paid by Borrower shall not exceed a criminal rate of
         interest from the date this Agreement was entered into.

         SECTION 10.13 Joint and Several Obligations. Each Borrower has
determined that it is in its best interest and in pursuance of its legitimate
business purposes to induce the Lenders to extend credit to the Borrowers
pursuant to this Agreement. Each Borrower acknowledges and represents that the
availability of the Commitments to each of the Borrowers benefits each Borrower
individually and that the Loans made will be for and inure to the benefit of
each of the Borrowers individually and as a group. Accordingly, each Borrower
shall be jointly and severally liable (as a principal and not as a surety,
guarantor or other accommodation party) for each and every representation,
warranty, covenant and obligation to be performed by the Borrowers under this
Agreement and the other Loan Documents, and each Borrower acknowledges that in
extending the credit provided herein the Agent and the Lenders are relying upon
the fact that the Obligations of each Borrower hereunder are the joint and
several obligations of a principal. The invalidity, unenforceability or
illegality of this Agreement or any other Loan Document as to one Borrower or
the release by the Agent or the Lenders of a Borrower hereunder or thereunder
shall not affect the Obligations of the other Borrowers under this Agreement or
the other Loan Documents, all of which shall otherwise remain valid and legally
binding obligations of the other Borrowers.

         SECTION 10.14 NO ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE OTHER
LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE
PARTIES.
