         SECTION 2.1. Commitments/Loans. On the terms and subject to the
conditions of this Agreement (including Article VI), each Lender severally
agrees to continue or make Loans pursuant to the Commitments described in this
Section 2.1.

         SECTION 2.1.1. Term B Loan Commitment. On the Closing Date, each Term B

         SECTION 2.1.2. Revolving Loan Commitment. From time to time on any
Business Day occurring prior to the Revolving Loan Commitment Termination Date,
each Revolving Lender severally will make loans in U.S. Dollars (relative to
such Lender, its "Revolving Loans") to the Borrower equal to such Lender's
Revolving Percentage of the aggregate amount of the Borrowing of Revolving Loans
requested by the Borrower to be made on such day. The Commitment of each
Revolving Lender described in this Section 2.1.2 to make Revolving Loans is
herein referred to as its "Revolving Loan Commitment". On the terms and subject
to the conditions hereof, the Borrower may from time to time borrow, prepay and
reborrow Revolving Loans.

         SECTION 2.1.3. Commitment to Issue Letters of Credit. From time to time
on any Business Day, an Issuer will issue, and each Revolving Lender will
participate in, the Letters of Credit, in accordance with Article IV.

         SECTION 2.1.4. Lenders Not Permitted or Required To Make Loans or Issue
or Participate in Letters of Credit Under Certain Circumstances. No Lender or
Issuer, as the case may be, shall be permitted or required to

                  (a) make its Term B Loan if, after giving effect thereto,

                           (i)      the aggregate outstanding principal amount
                  of all Term B Loans of all Lenders would exceed the Term B
                  Loan Commitment Amount, or

                           (ii)     the outstanding principal amount of the Term
                  B Loans of such Lender would exceed such Lender's Term
                  Percentage of the Term B Loan Commitment Amount;

                  (b) make any Revolving Loan if, after giving effect thereto,

                           (i)      the aggregate outstanding principal amount
                  of all Revolving Loans of all Lenders, together with all
                  Letter of Credit Outstandings, would exceed the Revolving
                  Commitment Amount, or

                           (ii)     the aggregate outstanding principal amount
                  of all Revolving Loans of such Lender, together with its
                  Revolving Percentage of all Letter of Credit Outstandings,
                  would exceed such Lender's Revolving Percentage of the
                  Revolving Commitment Amount; or

                  (c) issue (in the case of an Issuer) or participate in (in the
         case of each Revolving Lender) any Letter of Credit prior to the
         Revolving Loan Commitment Termination Date, if, after giving effect
         thereto

                           (i)      all Letter of Credit Outstandings together
                  with the aggregate outstanding principal amount of all
                  Revolving Loans of all Lenders would exceed the Revolving
                  Commitment Amount,

                           (ii)     in the case of the issuance of any Foreign
                  Currency Letter of Credit, the Equivalent Amount of all
                  Foreign Currency Letter of Credit

                                       32

<PAGE>

                  Outstandings would exceed the Foreign Currency Letter of
                  Credit Commitment Amount, or

                           (iii)    such Lender's Revolving Percentage of all
                  Letter of Credit Outstandings together with the aggregate
                  outstanding principal amount of all Revolving Loans of such
                  Lender would exceed such Lender's Revolving Percentage of the
                  then Revolving Commitment Amount.

         SECTION 2.2. Reduction of Revolving Commitment Amount and Term B Loans.
The Revolving Commitment Amount and the Term B Loans are subject to reduction
and prepayment from time to time pursuant to this Section 2.2. Each prepayment
of the Loans under this Section 2.2 shall be accompanied by accrued interest to
the date of such prepayment on the amount prepaid.

         SECTION 2.2.1. Optional Reduction. The Borrower may, from time to time
on any Business Day, make a voluntary prepayment of the Term B Loans in
accordance with Section 3.1.1. The Borrower may, from time to time on any
Business Day voluntarily reduce the Revolving Commitment Amount; provided,
however, that (i) all such reductions shall require at least three Business
Days' prior notice to the Agent and be permanent reductions of the Revolving
Commitment Amount, (ii) any partial reduction of the Revolving Commitment Amount
shall be in a minimum amount of $2,000,000 and in an integral multiple of
$500,000 and (iii) the last two sentences of Section 2.2.2(b) shall be
applicable to each such reduction.

         SECTION 2.2.2. Mandatory Reductions.

                  (a) There shall be a mandatory prepayment of the outstanding
         Term B Loans and reduction of the Revolving Commitment Amount by the
         amounts and in the circumstances set forth in Section 3.1.1.

                  (b) Any prepayment of the outstanding Term B Loans and
         reduction of the Revolving Commitment Amount described in clause (a)
         shall be effective on the first Business Day following the Borrower's
         receipt of any related Net Available Cash. All such amounts shall be
         applied to the ratable (i) prepayment of the outstanding Term B Loans
         and (ii) permanent reduction of the Revolving Commitment Amount. Any
         such reduction of the Revolving Commitment Amount shall be accompanied
         by prepayment of the Revolving Loans to the extent, if any, that the
         sum of (i) the aggregate principal amount of all outstanding Revolving
         Loans plus (ii) the aggregate Letter of Credit Outstandings exceeds the
         amount of the Revolving Commitment Amount as so reduced, provided that
         if the aggregate principal amount of Revolving Loans then outstanding
         is less than the amount of such excess (because Letter of Credit
         Outstandings constitute a portion thereof), the Borrower shall, to the
         extent of the balance of such excess, deposit an amount in cash in a
         cash collateral account, consistent with and subject to the procedures
         set forth in Section 4.7 hereof, established with the Agent for the
         benefit of the Lenders. The application of any prepayment pursuant to
         Section 2.2 shall be made, first, to Base Rate Loans and, second, to
         LIBO Rate Loans.

                                       33

<PAGE>

         SECTION 2.2.3. Post Default Application. After the occurrence and
during the continuance of an Event of Default, all optional and mandatory
prepayments of outstanding Term B Loans and reductions of the Revolving
Commitment Amount under Section 2.2.1 and Section 2.2.2 shall be applied to the
pro rata prepayment of all outstanding Revolving Loans and Term B Loans and
cash-collateralization of any Letters of Credit outstanding hereunder.

         SECTION 2.3. Borrowing Procedure. By delivering a Borrowing Request to
the Agent on or before 10:00 a.m., San Francisco time, on a Business Day, an
Authorized Officer of the Borrower may from time to time irrevocably request, on
not less than three days, in the case of LIBO Rate Loans, or one day in the case
of Base Rate Loans, nor more than five Business Days' notice, that a Borrowing
be made in a minimum amount of $2,000,000 or in the unused amount of the
applicable Commitment. The Agent shall promptly transmit the information in the
Borrower's request to each applicable Lender. On the terms and subject to the
conditions of this Agreement, each Borrowing shall be comprised of the type of
Loans, and shall be made on the Business Day, specified in such Borrowing
Request. On or before 11:00 a.m. (San Francisco time) on the Business Day
specified in such Borrowing Request each applicable Lender shall deposit with
the Agent same day funds in an amount equal to such Lender's applicable
Percentage of the requested Borrowing. Such deposit will be made to an account
which the Agent shall specify from time to time by notice to the Lenders. To the
extent funds are received from the applicable Lenders, the Agent shall make such
funds available to the Borrower by wire transfer to the accounts the Borrower
shall have specified in its Borrowing Request. No Lender's obligation to make
any Loan or L/C Advance shall be affected by any other Lender's failure to make
any Loan or L/C Advance.

         SECTION 2.4. Continuation and Conversion Elections. By delivering a
Continuation/ Conversion Notice to the Agent on or before 10:00 a.m., San
Francisco time, on a Business Day, an Authorized Officer of the Borrower may
from time to time irrevocably elect, on not less than three nor more than five
Business Days' notice that all, or any portion in an aggregate minimum amount of
$2,000,000 of any Loans be, in the case of Base Rate Loans, converted into LIBO
Rate Loans or, in the case of LIBO Rate Loans, be converted into a Base Rate
Loan or continued as a LIBO Rate Loan (in the absence of delivery of a
Continuation/Conversion Notice with respect to any LIBO Rate Loan at least three
Business Days before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically
convert to a Base Rate Loan); provided, however, that (i) each such conversion
or continuation shall be pro rated among the applicable outstanding Loans of all
Lenders, and (ii) no portion of the outstanding principal amount of any Loans
may be continued as, or be converted into, LIBO Rate Loans when any Default has
occurred and is continuing. The Agent shall promptly transmit the information in
each Continuation/Conversion Notice to each Lender.

         SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan; provided,
however, that such LIBO Rate Loan shall nonetheless be deemed to have been made
and to be held by such Lender, and the obligation of the Borrower to repay such
LIBO Rate Loan shall nevertheless be to such Lender for the account of such
foreign branch, Affiliate or international banking facility; provided, further,
that each Lender shall use reasonable efforts in making any such election to
minimize the costs payable by the Borrower

                                       34

<PAGE>

hereunder with respect to any Loan, Commitment or Letter of Credit. In addition,
the Borrower hereby consents and agrees that, for purposes of any determination
to be made for purposes of Section 5.1, 5.2, 5.3 or 5.4, it shall be
conclusively assumed that each Lender elected to fund all LIBO Rate Loans by
purchasing Dollar deposits in its LIBOR Office's interbank eurodollar market.

         SECTION 2.6. Notes; Register. Unless the Agent shall have been advised
by a Lender that it does not want to receive a Note, each Lender's Loans under
each of its Commitments shall be evidenced by a Note payable to the order of
such Lender in a maximum principal amount equal to such Lender's applicable
Percentage of the original applicable Commitment Amount. Whether or not a Loan
is evidenced by a Note, the Borrower hereby designates Agent to serve as its
agent, solely for the purposes of this Section, to maintain a register (the
"Register") on which Agent will record the name and address of each Lender, the
Commitments and Loans and each repayment in respect of the principal amount of
the Loans of each Lender from time to time. No payment with respect to the
outstanding principal and interest applicable for each of the Loans shall be
made to any Person other than the Person identified in such Register as the
Lender. Failure to make any such recordation or any errors in such recordation
shall not affect the Borrower's obligations in respect of such Loans. The
entries in the Register shall be conclusive and binding on the Borrower absent
manifest error. Upon reasonable notice and during normal business hours,
representatives of the Borrower may from time to time inspect the Register. The
Borrower hereby irrevocably authorizes each Lender to make (or cause to be made)
appropriate notations on the grid attached to such Lender's Notes (or on any
continuation of such grid), which notations, if made, shall evidence, inter
alia, the date of, the outstanding principal of, and the interest rate and
Interest Period applicable to the Loans and L/C Advances evidenced thereby. Such
notations shall be conclusive and binding on the Borrower absent manifest error;
provided, however, that the failure of any Lender to make any such notations
shall not limit or otherwise affect any Obligations of the Borrower or any other
Obligor.

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

         SECTION 3.1. Repayments and Prepayments. The Borrower shall repay in
full the unpaid principal amount of each Loan upon the applicable Stated
Maturity Date therefor.

         SECTION 3.1.1. Payment Terms. Prior to the Stated Maturity Date of each
Loan, the Borrower

                  (a) shall repay the Term B Loans of each Term B Lender in 16
         consecutive quarterly installments, commencing on October 15, 2003 and
         ending on July 15, 2007, each of which shall be in an amount equal to
         such Lender's Term Percentage multiplied by $500,000; provided that the
         final installment shall be in an amount equal to such Lender's Term
         Percentage multiplied by $192,500,000;

                  (b) may, from time to time on any Business Day, make a
         voluntary prepayment, in whole or in part, of the outstanding principal
         amount of any Loans; provided, however, that

                                       35

<PAGE>

                           (i)      any such prepayment shall be made pro rata
                  among Loans of the same type and, if applicable, having the
                  same Interest Period, of all Lenders;

                           (ii)     no such prepayment of any LIBO Rate Loan may
                  be made on any day other than the last day of the Interest
                  Period for such Loan, unless the Borrower also pays all losses
                  and expenses (for which the Borrower has received written
                  notice, including calculations in reasonable detail) as a
                  result of such prepayment as provided in Section 5.4;

                           (iii)    each such voluntary prepayment shall require
                  at least three but no more than five Business Days' prior
                  written notice to the Agent specifying whether such prepayment
                  is of Revolving Loans or (subject to clause (v) below) Term B
                  Loans or both;

                           (iv)     each such voluntary partial prepayment shall
                  be in an aggregate minimum amount of $2,000,000; and

                           (v)      no voluntary prepayment of the Term B Loans
                  shall be permitted unless the Revolving Commitment Amount is
                  reduced pursuant to Section 2.2.1 by at least a ratable
                  amount;

                  (c) shall, upon receipt by the Borrower or any Subsidiary of
         Net Available Cash from any Asset Sale, Monetization, Insurance Event
         or incurrence of secured Indebtedness permitted under Section 8.2.2(l)
         or (m) (excluding the CES Credit Facility), apply an amount equal to
         100% of such Net Available Cash pro rata to prepayments of the
         outstanding Term B Loans and the reductions of the Revolving Loan
         Commitments (and to any related prepayments of the then outstanding
         Revolving Loans and to cash collateralization the Letters of Credit),
         in each case as contemplated under Section 2.2.2; provided that
         conversion of any non-cash proceeds realized from any Asset Sale,
         Monetization or Insurance Event to cash (including both the principal
         amount of such non-cash proceeds and any interest attributable thereto)
         shall be deemed to be Net Available Cash upon such conversion and
         applied pursuant to this clause (c); provided, further, that no such
         prepayments and reductions shall be required as a consequence of:

                           (i)      without duplication of any other clause of
                  this paragraph (c), any Asset Sale or Monetization by the
                  Borrower of the Gilroy Receivable or any Asset Sale of
                  uninstalled turbines or equipment, to the extent that an
                  amount equal to the Net Available Cash with respect thereto is
                  applied within 355 days of the consummation of such Asset Sale
                  or Monetization (A) to make Restricted Capital Payments in
                  respect of Repayable Restricted Capital pursuant to Section
                  8.2.6(b)(B) or (B) to make Capital Expenditures to the extent
                  permitted under Section 8.2.7 (subject, however, to the Capex
                  Requirement); provided that to the extent any such Net
                  Available Cash is not so applied during such 355-day period,
                  the Borrower shall make the mandatory prepayments and
                  commitment reductions required by this paragraph (c) by the
                  close of business on the last day of such 355-day period in an
                  aggregate amount equal to the portion of such Net Available
                  Cash not so applied; or

<PAGE>

                           (ii)     without duplication of any other clause of
                  this paragraph (c), any Asset Sale or Monetization of, or
                  Insurance Event with respect to, assets that are not
                  Designated Assets or CES Assets, to the extent that an amount
                  equal to the Net Available Cash with respect thereto is
                  applied within 355 days after the consummation of such Asset
                  Sale or Monetization, or the receipt by the Borrower of the
                  Net Available Cash with respect to such Insurance Event, to
                  make Capital Expenditures to the extent permitted under
                  Section 8.2.7 (subject, however, to the Capex Requirement);
                  provided that to the extent any such Net Available Cash is not
                  so applied during such 355-day period, the Borrower shall make
                  the mandatory prepayments and commitment reductions required
                  by this paragraph (c) by the close of business on the last day
                  of such 355-day period in an aggregate amount equal to the
                  portion of such Net Available Cash not so applied; and
                  provided, further, that to the extent that at any time the
                  aggregate amount of Net Available Cash described in this
                  clause (ii) that has not been applied to make Capital
                  Expenditures in accordance with this clause (ii) shall exceed
                  the aggregate amount of Capital Expenditures then permitted to
                  be made with such Net Available Cash under Section 8.2.7
                  during the applicable 355-day period described above, an
                  amount equal to such excess shall, immediately thereafter, be
                  applied in accordance with the immediately preceding proviso;
                  or

                           (iii)    without duplication of any other clause of
                  this paragraph (c), any Permitted Sale; or

                  Person of an interest in a PUD pursuant to an agreement under
                  which such Person commits to develop or to provide financing
                  and/or funding to the Borrower or such Subsidiary solely for
                  the development of such PUD; provided that (A) the Fair Market
                  Value of such PUD interest (determined as of the date such
                  agreement is entered into) is less than $25,000,000, (B) the
                  aggregate Fair Market Value of all PUD interests (determined,
                  in the case of each PUD, as of the date the agreement with
                  respect to such PUD is entered into) sold, transferred,
                  leased, contributed or conveyed as set forth in this clause
                  (iv) is less than $100,000,000, (C) the Borrower or such
                  Subsidiary shall retain legal ownership of the entirety of
                  such PUD (except to the extent of the interest so sold,

                  transaction, deliver to the Agent such other information in
                  connection therewith as the Agent may reasonably request); or

                  (in the case of any such Canadian Gas Reserves and Canadian
                  geothermal energy assets); provided that to the extent any
                  such Net Available Cash is not so applied during such 355-day
                  period, the Borrower shall make the mandatory prepayments and

                  subject to such Asset Sales is less than Cdn$300,000,000 and
                  (y) the Borrower and/or one or more of its Subsidiaries shall

                  accordance with the terms of such royalty trust or income
                  fund) and such units shall be (I) if owned by the Borrower,
                  pledged to the Collateral Trustee (for the benefit of, among
                  others, the Lenders hereunder), (II) owned by a Pledged Entity
                  or (III) if material adverse tax consequences to the Borrower
                  or the Lenders would arise out of or result from the taking of
                  either of the actions set forth in clauses (I) or (II) above,
                  owned by a Subsidiary of a Pledged Entity; and

         9.3, repay all Loans, unless, pursuant to Section 9.3, only a portion
         of all Loans is so accelerated.

Each prepayment of any Loans made pursuant to this Section shall be without
premium or penalty, except as may be required by Section 5.4, and, in the case
of clause (c) above, shall be made by the close of business of the day of
receipt or deemed receipt of the relevant Net Available Proceeds. No voluntary
prepayment of principal of any Revolving Loans shall cause a reduction in the
Revolving Commitment Amount.

Notwithstanding anything to the contrary in Section 2.2.2 or 3.1.1, with respect
to the amount of any mandatory prepayment described in Section 2.2.2 or 3.1.1
that is allocated to Term B Loans (such amount, the "Term B Prepayment Amount")
at any time when Revolving Loan Commitments remain outstanding, the Borrower
will, in lieu of applying such amount to the prepayment of the Term B Loans, on
the date specified for such prepayment, give the Agent telephonic notice
(promptly confirmed in writing) requesting that the Agent prepare and provide to
each Term B Lender a notice (each, a "Prepayment Option Notice") as described
below. As promptly as practicable after receiving such notice from the Borrower,
the Agent will send to each Term B Lender a Prepayment Option Notice, which
shall be in the form of Exhibit G, and shall include an offer by the Borrower to
prepay on the date (each a "Mandatory Prepayment Date") that is ten calendar
days after the date of the Prepayment Option Notice (but in no event later than
the date which is 365 days after the applicable Asset Sale, Monetization or
Insurance Event) the relevant Term B Loans of such Lender by an amount equal to
the portion of the Term B Prepayment Amount indicated in such Lender's
Prepayment Option Notice as being applicable to such Lender's Term B Loans. On
the Mandatory Prepayment Date, (i) the Borrower shall pay to the relevant Term B
Lenders the aggregate amount necessary to prepay that portion of the outstanding
Term B Loans in respect of which such Lenders have accepted prepayment as
described above and (ii) the Borrower shall permanently reduce the Revolving
Loan Commitments (and prepay Revolving Loans and cash collateralize the Letters
of Credit) as

                                       39

<PAGE>

contemplated under Section 2.2.2 by an amount equal to the portion of the Term B
Prepayment Amount not accepted by the relevant Term B Lenders.

         SECTION 3.1.2. Post Default Application of Payments. Notwithstanding
any provision of Sections 2.2.2 or 3.1.1 to the contrary, after the occurrence
and during the continuance of an Event of Default, all optional and mandatory
payments under Section 3.1.1 shall be applied first to pay any fees and expenses
then due and owing hereunder, second to the pro rata payment of accrued and
unpaid interest on all Loans hereunder and third as set forth in Section
2.2.2(b).

         SECTION 3.2. Interest Provisions. Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this Section 3.2.

         SECTION 3.2.1. Rates. Pursuant to an appropriately delivered Borrowing
Request or Continuation/Conversion Notice, the Borrower may elect that Loans
comprising a Borrowing accrue interest at a rate per annum:

                  (a)      on that portion maintained from time to time as a
         Base Rate Loan, equal to the sum of the Alternate Base Rate from time
         to time in effect plus the Applicable Margin; and

                  (b)      on that portion maintained as a LIBO Rate Loan,
         during each Interest Period applicable thereto, equal to the sum of the
         LIBO Rate (Reserve Adjusted) for such Interest Period plus the
         Applicable Margin.

         The "LIBO Rate (Reserve Adjusted)" means, relative to any Loan to be
made, continued or maintained as, or converted into, a LIBO Rate Loan for any
Interest Period, a rate per annum (rounded upwards, if necessary, to the nearest
1/16 of 1%) determined pursuant to the following formula:

         LIBO Rate                 =                        LIBO Rate
(Reserve Adjusted)                               -------------------------------
                                                 1.00 - LIBOR Reserve Percentage

The LIBO Rate (Reserve Adjusted) for any Interest Period for LIBO Rate Loans
will be determined by the Agent on the basis of the LIBOR Reserve Percentage in
effect on, and the applicable rates furnished to and received by the Agent from
Scotia Capital, two Business Days before the first day of such Interest Period.

         "LIBO Rate" means, relative to any Interest Period for LIBO Rate Loans,
the rate of interest equal to the average (rounded upwards, if necessary, to the
nearest 1/16 of 1%) of the rates per annum at which Dollar deposits in
immediately available funds are offered to Scotia Capital's LIBOR Office in the
London interbank market as at or about 11:00 a.m. London time two Business Days
prior to the beginning of such Interest Period for delivery on the first day of
such Interest Period, and in an amount approximately equal to the amount of
Scotia Capital's LIBO Rate Loan and for a period approximately equal to such
Interest Period.

         "LIBOR Reserve Percentage" means, for each day of any Interest Period
for LIBO Rate Loans, the reserve percentage (expressed as a decimal) equal to
the maximum aggregate reserve requirements (including all basic, emergency,
supplemental, marginal and other reserves and

                                       40

<PAGE>

taking into account any transitional adjustments or other scheduled changes in
reserve requirements) specified from time to time under regulations issued from
time to time by the F.R.S. Board and then applicable to assets or liabilities
consisting of and including "Eurocurrency Liabilities", as currently defined in
Regulation D of the F.R.S. Board.

         All LIBO Rate Loans shall bear interest from and including the first
day of the applicable Interest Period to (but not including) the last day of
such Interest Period at the interest rate determined as applicable to such LIBO
Rate Loan.

         SECTION 3.2.2. Post-Maturity Rates. After the date any principal amount
of any Loan is due and payable (whether on the applicable Stated Maturity Date,
upon acceleration or otherwise), or after any other monetary Obligation of the
Borrower shall have become due and payable, the Borrower shall pay, but only to
the extent permitted by law, interest (after as well as before judgment) on such
amounts at a rate per annum equal to the Alternate Base Rate plus the Applicable
Margin plus a margin of 2%.

         SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be
payable, without duplication:

                  (a) on the Stated Maturity Date therefor;

                  (b) on the date of any optional or required payment or
         prepayment, in whole or in part, of principal outstanding on such Loan
         being prepaid;

                  (c) with respect to Base Rate Loans, on each Quarterly Payment
         Date occurring after the Closing Date;

                  (d) with respect to LIBO Rate Loans, on the last day of each
         applicable Interest Period (and, if such Interest Period shall exceed
         three months, at the end of the third month of such Interest Period);

                  (e) with respect to any Base Rate Loans converted into LIBO
         Rate Loans on a day when interest would not otherwise have been payable
         pursuant to clause (c), on the date of such conversion; and

                  (f) on that portion of any Loans the Stated Maturity Date of
         which is accelerated pursuant to Section 9.2 or Section 9.3,
         immediately upon such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount is due and
payable (whether on the applicable Stated Maturity Date, upon acceleration or
otherwise) shall be payable upon demand.

         SECTION 3.3. Fees. The Borrower agrees to pay the fees set forth in
this Section 3.3. All such fees shall be non-refundable.

         SECTION 3.3.1. Commitment Fees. The Borrower agrees to pay to the Agent
for the account of each Revolving Lender, for the period (including any portion
thereof when any of its Commitments are suspended by reason of the Borrower's
inability to satisfy any condition of

                                       41

Article VI) commencing on the Closing Date and continuing through the Revolving
Loan Commitment Termination Date, a commitment fee (the "Commitment Fee") at the
rate of 0.50% per annum, calculated on such Lender's Revolving Percentage of the
average daily unused portion of the Revolving Commitment Amount. Commitment Fees

commencing with the first such day following the Closing Date, and on the
Revolving Loan Commitment Termination Date.

         SECTION 3.3.2. Fees. The Borrower agrees to pay to the Agent and the
Lenders for their own accounts the fees described in the Fee Letters, at the

upon which) such Letter of Credit expires or is returned to the Issuer that
issued such Letter of Credit, a fee, in Dollars, on the average daily stated
amount of such Letter of Credit (or the Equivalent Amount thereof with respect
to Foreign Currency Letters of Credit) calculated at a per annum rate equal to
the Applicable Margin for LIBO Rate Loans in effect from time to time. Such fee
shall be payable by the Borrower in arrears on each Quarterly Payment Date, and
on the date of termination or expiry of the last Letter of Credit outstanding
hereunder (for any period then ending for which such fee shall not theretofore
have been paid), commencing on the first such date after the issuance of such
Letter of Credit.

         SECTION 3.3.4. Letter of Credit Issuing Fee. The Borrower agrees to pay
to the Agent, for the account of each Issuer, an issuing fee, in Dollars, for
each Letter of Credit issued by such Issuer for the period from and including
the date of issuance of such Letter of Credit to (and including) the date upon
which such Letter of Credit expires or is returned to the Issuer that issued
such Letter of Credit at such rates as may be agreed in writing by the Borrower
and the Issuers from time to time. Such fee shall be payable by the Borrower in
arrears on each Quarterly Payment Date and on the date of termination or expiry
of the last Letter of Credit outstanding hereunder for any period then ending
for which such fee shall not theretofore have been paid, commencing on the first
such date after the issuance of such Letter of Credit. For any Foreign Currency

         beneficiary thereof; and

                  (c) on or prior to its Stated Expiry Date

                           (i)      terminate immediately upon notice to the
                  Issuer thereof from the beneficiary thereunder that all
                  obligations covered thereby have been terminated, paid, or
                  otherwise satisfied in full and surrender by the beneficiary

                           (ii)     reduce in part immediately and to the extent
                  the beneficiary thereunder has notified the Issuer thereof
                  that the obligations covered thereby have been paid or
                  otherwise satisfied in part and that the Letter of Credit may
                  be reduced.

         SECTION 4.2. Issuances and Extensions. On the terms and subject to the
conditions of this Agreement (including Article VI), the Issuer to whom notice

each Letter of Credit issued and any amendment thereto) and will notify the
beneficiary under any Letter of Credit of

                                       43

Percentage, be deemed irrevocably to have participated in the issuance of such
Letter of Credit and shall be responsible to pay promptly to the Issuer thereof
such Lender's Revolving Percentage of any unreimbursed drawings under a Letter
of Credit which have not been reimbursed by the Borrower in accordance with
Section 4.5, or which have been reimbursed by the Borrower but must be returned,
restored or disgorged by the Issuer thereof for any reason, and each Revolving
Lender shall, to the extent of its Revolving Percentage, be entitled to receive
from the Agent a ratable portion of the letter of credit fees received by the
Agent pursuant to Section 3.3.3, with respect to each Letter of Credit. Each
Revolving Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this Section 4.4 in respect of Letters of Credit
issued or amended while such Revolving Lender remains a party to this Agreement
is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment of any Letter of Credit or the occurrence
and continuation of a Default or Event of Default or reduction or termination of
the Revolving Loan Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever. In the event that
the Borrower shall fail to reimburse the Issuer thereof, or if for any reason
Revolving Loans shall not be made to fund any Reimbursement Obligation, all as
provided in Section 4.5 and Section 4.6 and in an amount equal to the amount of
any drawing honored by such Issuer under a Letter of Credit issued by it, or in
the event such Issuer must for any reason return or disgorge such reimbursement,
such Issuer shall promptly notify each Revolving Lender of the unreimbursed
amount of such drawing and of such Revolving Lender's respective participation
therein. Each Revolving Lender shall make available to such Issuer, whether or
not any Default shall have occurred and be continuing, an amount equal to its
respective participation in same day or immediately available funds at the
office of such Issuer specified in such notice not later than 2:00 p.m., New
York time, on the Business Day (under the laws of the jurisdiction of such
Issuer) after the date notified by such Issuer. In the event that any Revolving
Lender fails to make available to an Issuer the amount of such Revolving
Lender's participation in such Letter of Credit as provided herein, such Issuer
shall be entitled to recover such amount on demand from such Revolving Lender
together with interest at the daily average Federal Funds Rate for three
Business Days and thereafter at the Alternate Base Rate plus 2%. Nothing in this
Section shall be deemed to prejudice the right of any Revolving Lender to
recover from any Issuer any amounts made available by such Revolving Lender to
an Issuer pursuant to this Section in the event that it is determined by a court
of competent jurisdiction that the payment with respect to a Letter of Credit by
the Issuer thereof in respect of which payment was made by such Revolving Lender
constituted gross

                                       44

<PAGE>

negligence or willful misconduct on the part of such Issuer. Each Issuer shall
distribute to each Revolving Lender which has paid all amounts payable by it
under this Section with respect to any Letter of Credit issued by such Issuer
such Lender's Revolving Percentage of all payments received by such Issuer from
the Borrower in reimbursement of drawings honored by such Issuer under such
Letter of Credit when such payments are received.

         SECTION 4.5. Disbursements. Each Issuer will notify the Borrower and
the Agent promptly of the presentment for payment of any Letter of Credit issued
by it, together with notice of the date (a "Disbursement Date") such payment
shall be made (each such payment, a "Disbursement"). Unless otherwise agreed by
the applicable Issuer and the Borrower, drawings under any Letter of Credit
issued under Section 4.1 shall be made on sight. Subject to the terms and
provisions of such Letter of Credit, each Issuer shall make such payment to the
beneficiary (or its designee) of such Letter of Credit. Prior to 2:00 p.m., New
York time, on the Disbursement Date, the Borrower will reimburse each Issuer for
all amounts in the currency which it has disbursed under the Letter of Credit or
will notify such Issuer that it elects to make such reimbursement by requesting
the Revolving Lenders to make a Revolving Loan in the Equivalent Amount of such
required reimbursement. If Borrower elects to make such reimbursement by
requesting a Revolving Loan in such amount and the conditions precedent in
Article VI shall have been satisfied, the Revolving Lenders shall fund such
Reimbursement Obligation by making Base Rate Loans in the appropriate Equivalent
Amounts in accordance with Section 2.3. To the extent an Issuer is not
reimbursed in full on the date payment is made under a Letter of Credit, the
Borrower's Reimbursement Obligation shall accrue interest at the Alternate Base
Rate plus the Applicable Base Rate Margin for two Business Days and thereafter
at the Post-Maturity Rate described in Section 3.2.2, payable on demand, until
reimbursed in full. In the event an Issuer is not reimbursed by the Borrower on
any Disbursement Date, or if an Issuer must for any reason return or disgorge
such reimbursement, the Revolving Lenders (including such Issuer) shall fund the
Reimbursement Obligation therefor by making, on the next Business Day, Loans
(or, if the Revolving Loan Commitments shall no longer then be in effect,
advances ("L/C Advances") that are payable on demand and have the same
characteristics as Loans and which shall be Obligations hereunder) in the
appropriate Equivalent Amounts which are Base Rate Revolving Loans (or L/C
Advances bearing interest by reference to the Base Rate) (except that such
Revolving Loans or L/C Advances shall be made upon demand by the Agent rather
than upon notice by the Borrower and shall be made, notwithstanding anything in
this Agreement to the contrary, without regard to the satisfaction of the
conditions precedent to the making of Revolving Loans set forth in Article VI of
this Agreement and notwithstanding any termination of the Commitments). Each
Revolving Lender's obligation to make Revolving Loans or L/C Advances in the
amount of its Revolving Percentage of any unreimbursed amounts outstanding under
a Letter of Credit pursuant hereto is several, and not joint or joint and
several. Except as specifically noted herein, all terms and provisions that are
applicable to Revolving Loans under this Agreement shall be equally applicable
to L/C Advances. For example, and without limitation, the provisions of Sections
3.1.1(c), 3.2.2, 3.2.3, 5.5, 5.6, 5.8, 5.9, 7.13, 8.2.10(c), 9.1.1, 10.5,
11.1(c), 11.4(a) and 11.11 shall equally apply to L/C Advances as well as Loans.

         SECTION 4.6. Reimbursement. The Borrower's obligation (a "Reimbursement
Obligation") under Section 4.5 to reimburse an Issuer with respect to each
disbursement (including interest thereon), and each Revolving Lender's
obligation to make participation

                                       45

<PAGE>

payments in each drawing which has not been reimbursed by the Borrower, shall be
absolute and unconditional under any and all circumstances and irrespective of
any setoff, counterclaim, or defense to payment which the Borrower may have or
have had against any Revolving Lender or any beneficiary of a Letter of Credit,
including any defense based upon the occurrence of any Default, any draft,
demand or certificate or other document presented under a Letter of Credit
proving to be forged, fraudulent, invalid or insufficient, the failure of any
disbursement to conform to the terms of the applicable Letter of Credit (if, in
such Issuer's good faith opinion, such disbursement is determined to be
appropriate) or any non-application or misapplication by the beneficiary of the
proceeds of such disbursement, or the legality, validity, form, regularity, or
enforceability of such Letter of Credit; provided, however, that nothing herein
shall adversely affect the right of the Borrower to commence any proceeding
against an Issuer for any wrongful disbursement made by such Issuer under a
Letter of Credit as a result of acts or omissions constituting gross negligence
or willful misconduct on the part of such Issuer.

         SECTION 4.7. Cash Collateral. In the circumstances set forth in Section
2.2.2(b) or 3.1.1, or upon the occurrence and during the continuation of any
Event of Default described in Section 9.1.9, or, at the election of the Agent
acting on instructions from the Required Revolving Lenders, upon notice to the
Borrower after the occurrence and during the continuation of any other Event of
Default, an amount equal to that portion of Letter of Credit Outstandings
attributable to outstanding and undrawn Letters of Credit (or a lesser amount,
if applicable, required pursuant to Section 2.2.2(b)) shall be deemed to have
been paid or disbursed by the Issuers under the Letters of Credit
(notwithstanding that such amount may not in fact have been paid or disbursed),
and, upon notification by the Issuers to the Agent and the Borrower of its
obligations under this Section, the Borrower shall be immediately obligated to
reimburse the Agent the amount deemed to have been so paid or disbursed by the
Issuers. Any amounts so received by the Agent from the Borrower pursuant to this
Section shall be held as collateral security for the repayment of the Borrower's
obligations in connection with the Letters of Credit. At any time when such a
Letter of Credit shall terminate and all L/C Advances and Obligations of the
Borrower to the Issuers in respect of such Letter of Credit are either
terminated or paid or reimbursed to the Revolving Lenders and the Issuers in
full, the Obligations of the Borrower under this Section with respect to such
Letter of Credit shall also terminate (subject, however, to reinstatement in the
event any payment in respect of such Letter of Credit is recovered in any manner
from any Issuer or Revolving Lender), and the Agent will return to the Borrower
the aggregate amount deposited by the Borrower with the Agent in respect of such
Letter of Credit and not theretofore applied by the Agent to any Reimbursement
Obligation.

         At such time when all Events of Default shall have been cured or
waived, the Agent shall return to the Borrower all amounts then on deposit with
it pursuant to this Section. All amounts on deposit pursuant to this Section
shall, until their application to any Reimbursement Obligation or their return
to the Borrower, as the case may be, bear interest at the daily average Federal
Funds Rate from time to time in effect (net of the costs of any reserve
requirements, in respect of amounts on deposit pursuant to this Section,
pursuant to F.R.S. Board Regulation D), which interest shall be held by the
Agent as additional collateral security for the repayment of the Borrower's
Obligations in connection with the Letters of Credit issued by the Issuers.

         SECTION 4.8. Nature of Reimbursement Obligations. The Borrower shall
assume all risks of the acts, omissions, or misuse of any Letter of Credit by
the beneficiary thereof. Neither

                                       46

<PAGE>

any Issuer (except to the extent of its own gross negligence or willful
misconduct) nor any Revolving Lender shall be responsible for:

                  (a) the form, validity, sufficiency, accuracy, genuineness, or
         legal effect of any document submitted by any party in connection with
         the application for and issuance of a Letter of Credit, even if it
         should in fact prove to be in any or all respects invalid,
         insufficient, inaccurate, fraudulent, or forged;

                  (b) the form, validity, sufficiency, accuracy, genuineness, or
         legal effect of any instrument transferring or assigning or purporting
         to transfer or assign a Letter of Credit or the rights or benefits
         thereunder or proceeds thereof in whole or in part, which may prove to
         be invalid or ineffective for any reason;

                  (c) failure of the beneficiary to comply fully with conditions
         required in order to demand payment under a Letter of Credit;

                  (d) errors, omissions, interruptions, or delays in
         transmission or delivery of any messages, by mail, cable, telegraph,
         telex, or otherwise;

                  (e) any error, omission, interruption, loss or delay in the
         transmission or delivery of any draft, notice or other communication
         under or relating to any Letter of Credit (including any document
         required in order to make a Disbursement thereunder) or of the proceeds
         thereof;

                  (f) any error in interpretation of technical terms;

                  (g) the performance of any transaction which underlies any
         Letter of Credit;

                  (h) any act or omission of any Person other than the Issuer
         and the Revolving Lenders;

                  (i) loss or destruction of any draft, demand, or document in
         transit or in the possession of others;

                  (j) lack of knowledge of any particular trade usage (other
         than standard United States and Western European banking usage as used
         in the normal course of business); or

                  (k) any consequence arising from causes beyond the control of
         the Issuer and the Revolving Lenders.

None of the foregoing shall affect, impair, or prevent the vesting of any of the
rights or powers granted any Issuer or any Revolving Lender hereunder. In
furtherance and extension, and not in limitation or derogation, of any of the
foregoing, any action taken or omitted to be taken by an Issuer in good faith
and which is not grossly negligent shall be binding upon the Borrower and shall
not put such Issuer under any resulting liability to the Borrower; provided,
however, that nothing herein shall relieve any Issuer, the Agent or any
Revolving Lender for any liability for its gross negligence or willful
misconduct.

         SECTION 4.9. Increased Costs; Indemnity. If by reason of

                  (a) any change after the Closing Date in applicable law,
         regulation, rule, decree or regulatory requirement or any change after
         the Closing Date in the interpretation or application by any judicial
         or regulatory authority of any law, regulation, rule, decree or
         regulatory requirement, or

                  (b) compliance by any Issuer or any Revolving Lender with any
         new or modified (after the Closing Date) direction, request or
         requirement (whether or not having the force of law) of any
         governmental or monetary authority, including Regulation D of the
         F.R.S. Board:

                           (i)      any Issuer or any Revolving Lender shall be
                  subject to any tax (other than franchise taxes or taxes
                  measured by net income or receipts), levy, charge or
                  withholding of any nature or to any variation thereof or to
                  any penalty with respect to the maintenance or fulfillment of
                  its obligations under this Article IV, whether directly or by
                  such being imposed on or suffered by any Issuer or any
                  Revolving Lender;

                           (ii)     any reserve, deposit or similar requirement
                  is or shall be applicable, imposed or modified in respect of
                  any Letters of Credit issued by any Issuer or participations
                  therein purchased by any Revolving Lender; or

                           (iii)    there shall be imposed on any Issuer or any
                  Revolving Lender any other condition regarding this Article
                  IV, any Letter of Credit or any participation therein;

and the result of the foregoing is directly or indirectly to increase the cost
to an Issuer or such Revolving Lender of issuing, making or maintaining any
Letter of Credit or of purchasing or maintaining any participation therein, or
to reduce any amount receivable in respect thereof by such Issuer or such
Revolving Lender, then and in any such case such Issuer or such Revolving Lender
may, at any time after the additional cost is incurred or the amount received is
reduced, notify the Borrower thereof and provide Borrower with data and
calculations supporting such costs, and the Borrower shall pay such amounts as
such Issuer or Revolving Lender may specify to be necessary to compensate such
Issuer or Revolving Lender for such additional cost or reduced receipt within
ten (10) Business Days after receiving such notice, together with interest on
such amount from the date of receipt of such notice until payment in full
thereof at a rate equal at all times to the Alternate Base Rate plus the
Applicable Margin; provided, however, that Section 5.6, rather than this Section
4.9 shall govern Borrower's obligations with respect to Taxes relating to
payments by the Borrower described in the first sentence of Section 5.6(a). The
good faith determination by an Issuer or Revolving Lender, as the case may be,
of any amount due pursuant to this Section 4.9, as set forth in a statement
setting forth the calculation thereof in reasonable detail, shall, in the
absence of manifest error, be final and conclusive and binding on all of the
parties hereto. In addition to amounts payable as elsewhere provided in this
Article IV, the Borrower hereby agrees to protect, indemnify, pay and save the
Issuers and the Revolving Lenders harmless from and against any and all claims,
demands, liabilities, damages, losses,

                                       48

<PAGE>

costs, charges and expenses (including reasonable attorneys' fees) which any
Issuer or any Revolving Lender may incur or be subject to as a consequence,
direct or indirect, of

                  (x) the issuance of the Letters of Credit, other than as a
         result of the gross negligence or willful misconduct of an Issuer as
         determined by a court of competent jurisdiction, or

                  (y) the failure of an Issuer to honor a drawing under any
         Letter of Credit as a result of any act or omission, whether rightful
         or wrongful, of any present or future de jure or de facto government or
         governmental authority.

         SECTION 4.10. Existing Letters of Credit. On the Closing Date, the
Existing Letters of Credit shall continue to be deemed for all purposes to be
Letters of Credit outstanding under this Agreement and entitled to the benefits
of this Agreement and the other Loan Documents, and shall be governed by the
applications and agreements pertaining thereto and by this Agreement. Each
Revolving Lender shall be deemed to, and hereby irrevocably and unconditionally
agrees to, purchase from the Issuers on the Closing Date a participation in each
such Letter of Credit and each drawing thereunder in an amount equal to the
product of (i) such Lender's Revolving Percentage times (ii) the maximum amount
available to be drawn under such Letter of Credit and the amount of such
drawing, respectively. For purposes of Section 2.1.2, the Existing Letters of
Credit shall be deemed to utilize pro rata the Revolving Loan Commitment of each
Revolving Lender.

         SECTION 4.11. Equivalent Amount Determinations. For purposes of
determining the amount of Foreign Currency Letter of Credit Outstandings and for
purposes of calculating fees payable under Section 3.3.3 with respect to Foreign
Currency Letter of Credit Outstandings, the principal amount of such Foreign
Currency Letter of Credit Outstandings shall be deemed to be, as of any date of
determination, the Equivalent Amount thereof at such date. The initial
Equivalent Amount of any Foreign Currency Letter of Credit shall be determined
by the Issuer of such Letter of Credit and notified by such Issuer in writing to
the Agent and the Borrower on the date of issuance thereof. If a Disbursement is
made by an Issuer under any Foreign Currency Letter of Credit, the Equivalent
Amount of such Disbursement shall be determined by the relevant Issuer on the
Disbursement Date related thereto, and such Issuer shall notify the Agent and
the Borrower promptly of such Equivalent Amount.

         SECTION 4.12. Currency Fluctuations, etc. Not later than 12:00 p.m.,
New York time, on each Quarterly Payment Date and on each other date specified
by the Agent (each, an "Equivalent Amount Determination Date"), each Issuer
shall determine the Equivalent Amount as of such Equivalent Amount Determination
Date with respect to each Foreign Currency for which there are at such time
outstanding Foreign Currency Letters of Credit issued by such Issuer or in
respect thereof (after giving effect to any Loans to be made or repaid or
Letters of Credit to be issued or Reimbursement Obligations to be repaid on such
date). Each Issuer shall notify the Borrower, the Revolving Lenders and the
Agent of such Equivalent Amount. The Equivalent Amount so determined shall
become effective on the first Business Day immediately following the relevant
Equivalent Amount Determination Date (each, a "Reset Date") and shall remain
effective until the next succeeding Reset Date.

                                   ARTICLE V

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

         SECTION 5.1. LIBO Rate Lending Unlawful. If any Lender shall determine
in good faith (which good faith determination shall, upon notice thereof to the
Borrower and the Lenders, be conclusive and binding on the Borrower) that the
introduction of or any change in or in the interpretation of any law makes it
unlawful, or any central bank or other governmental authority asserts that it is
unlawful, for such Lender to make, continue or maintain any Loan as, or to
convert any Loan into, a LIBO Rate Loan, the obligations of all Lenders to make,
continue, maintain or convert into any such Loans shall, upon such
determination, forthwith be suspended until such Lender shall notify the Agent
that the circumstances causing such suspension no longer exist, and all LIBO
Rate Loans of such type shall automatically convert into Base Rate Loans at the
end of the then current Interest Periods with respect thereto or sooner, if
required by such law or assertion. Until such time as such Lender's obligation
to make, continue and maintain LIBO Rate Loans is reinstated, the Borrower shall
have the right (with the prior written consent of the Agent, which consent shall
not be unreasonably withheld) to replace such affected Lender by obtaining
another financial institution that is willing to purchase such affected Lender's
interest herein for the full amount of any outstanding Loans, Reimbursement
Obligations and other amounts owed hereunder (including principal, accrued
interest, breakage costs and any other unreimbursed costs and expenses owed to
such Lender), to assume such affected Lender's obligations under this Agreement
and to become a Lender hereunder. In such event, the affected Lender shall, upon
ten (10) Business Days notice from Borrower, assign one hundred percent (100%)
of its interest hereunder to such replacement lender for the price described in
the previous sentence.

         SECTION 5.2. Deposits Unavailable. If the Agent shall have determined
that

                  (a) Dollar deposits in the relevant amount and for the
         relevant Interest Period are not available to the Agent or any Lender
         in its relevant market; or

                  (b) by reason of circumstances affecting the Agent's or any
         Lender's relevant market, adequate means do not exist for ascertaining
         the interest rate applicable hereunder to LIBO Rate Loans,

then, upon notice from the Agent to the Borrower and the Lenders, the
obligations of all Lenders under Section 2.3 and Section 2.4 to make or continue
any Loans as, or to convert any Loans into, LIBO Rate Loans shall forthwith be
suspended (at the end of the applicable Interest Period, in the case of
outstanding LIBO Rate Loans) until the Agent shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

         SECTION 5.3. Increased LIBO Rate Loan Costs, etc. The Borrower agrees
to reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or of converting (or of its obligation to convert) any
Loans into, LIBO Rate Loans as a result in any change after the Closing Date, in
applicable law, regulation, rule, decree or regulatory requirement or in the
interpretation or

                                       50

<PAGE>

application by any judicial or regulatory authority of any law, regulation,
rule, decree or regulatory requirement. Such Lender shall promptly notify the
Agent and the Borrower in writing of the occurrence of any such event, such
notice to state, in reasonable detail, the reasons therefor and the additional
amount required fully to compensate such Lender for such increased cost or
reduced amount. Such additional amounts shall be payable by the Borrower
directly to such Lender within five Business Days of its receipt of such notice,
and such notice shall, in the absence of manifest error and if given in good
faith, be conclusive and binding on the Borrower. If such increased costs do not
affect all of the Lenders, the Borrower shall have the right (with the prior
written consent of the Agent, which consent shall not be unreasonably withheld)
to replace the affected Lender by obtaining another financial institution that
is willing to purchase such affected Lender's interest herein for the full
amount of any outstanding Loans and Reimbursement Obligations (principal and
accrued interest), to assume such affected Lender's obligations under this
Agreement and to become a Lender hereunder. In such event, the affected Lender
shall, upon five (5) Business Days notice from Borrower, assign one hundred
percent (100%) of its interests hereunder to such replacement lender for the
price described in the previous sentence and thereafter such Lender shall have
no further obligations hereunder.

         SECTION 5.4. Funding Losses. In the event any Lender shall incur any
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a LIBO
Rate Loan) as a result of

                  (a) any conversion or repayment or prepayment of the principal
         amount of any LIBO Rate Loans on a date other than the scheduled last
         day of the Interest Period applicable thereto;

                  (b) any Loans not being made as LIBO Rate Loans in accordance
         with the Borrowing Request therefor other than as a result of any act
         or omission by such Lender;

                  (c) any Loans not being continued as, or converted into, LIBO
         Rate Loans in accordance with the Continuation/ Conversion Notice
         therefor other than as a result of any act or omission by such Lender;
         or

                  (d) any LIBO Rate Loan not being prepaid in accordance with a
         notice of prepayment,

then, upon the written notice of such Lender to the Borrower (with a copy to the
Agent), the Borrower shall, within five Business Days of its receipt thereof,
pay directly to such Lender such amount as will (in the reasonable determination
of such Lender) reimburse such Lender for such loss or expense. Such written
notice (which shall include calculations in reasonable detail and all
information and documentation reasonably necessary to support such calculations)
shall, in the absence of manifest error, be conclusive and binding on the
Borrower.

         SECTION 5.5. Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank,

                                       51

<PAGE>

regulator or other governmental authority causes the amount of capital required
or expected to be maintained by any Lender or any Person controlling such Lender
attributable to or based upon the Loans, the Letters of Credit or Commitments
hereunder to be increased, and such Lender determines (in its reasonable
discretion) that the rate of return on its or such controlling Person's capital
as a consequence of its Commitments, issuance of or participation in Letters of
Credit or the Loans made by such Lender is reduced to a level below that which
such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrower, the Borrower shall immediately pay
directly to such Lender additional amounts sufficient to compensate such Lender
or such controlling Person for such reduction in rate of return. A statement of
such Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error and if
made in good faith, be conclusive and binding on the Borrower. In determining
such amount, such Lender may use any method of averaging and attribution that it
(in its good faith discretion) shall deem applicable.

         SECTION 5.6. Taxes. (a) Subject to each Lender's compliance with this
Section 5.6, all payments by the Borrower of principal of, and interest on, the
Loans and all other amounts payable hereunder shall be made free and clear of
and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of
any nature whatsoever imposed by any taxing authority, but excluding franchise
taxes and taxes imposed on or measured by any Lender's net income or receipts
(such non-excluded items being called "Taxes"). In the event that any
withholding or deduction from any payment to be made by the Borrower hereunder
is required in respect of any Taxes pursuant to any applicable law, rule or
regulation, then the Borrower will

                           (i)      pay directly to the relevant authority the
                  full amount required to be so withheld or deducted;

                           (ii)     promptly forward to the Agent an official
                  receipt or other documentation satisfactory to the Agent
                  evidencing such payment to such authority; and

                           (iii)    pay to the Agent for the account of the
                  Lenders such additional amount or amounts as is necessary to
                  ensure that the net amount actually received by each Lender
                  will equal the full amount such Lender would have received had
                  no such withholding or deduction been required.

         Moreover, if any Taxes are directly asserted against the Agent or any
         Lender with respect to any payment received by the Agent or such Lender
         hereunder, the Agent or such Lender may pay such Taxes and the Borrower
         will promptly pay such additional amounts (including any penalties,
         interest or expenses) as is necessary in order that the net amount
         received by such person after the payment of such Taxes (including any
         Taxes on such additional amount) shall equal the amount such person
         would have received had not such Taxes been asserted.

                  If the Borrower fails to pay any Taxes when due to the
         appropriate taxing authority or fails to remit to the Agent, for the
         account of the respective Lenders, the

                                       52

<PAGE>

         required receipts or other required documentary evidence, the Borrower
         shall indemnify the Lenders for any incremental Taxes, interest or
         penalties that may become payable by any Lender as a result of any such
         failure. For purposes of this Section 5.6, a distribution hereunder by
         the Agent or any Lender to or for the account of any Lender shall be
         deemed a payment by the Borrower.

                  (b) Upon the request of the Borrower or the Agent, each Lender
         (including, any participant or Assignee Lender) that is (a) organized
         under the laws of the United States or a state thereof shall execute
         and deliver to the Borrower and the Agent one or more (as the Borrower
         or the Agent may reasonably request) appropriately completed United
         States Internal Revenue Service Forms W-9 (or any successor forms or
         documents) and (b) organized under the laws of a jurisdiction other
         than the United States shall, prior to the due date of and as a
         condition to any payments hereunder or under the Notes, execute and
         deliver to the Borrower and the Agent one or more (as the Borrower or
         the Agent may reasonably request) United States Internal Revenue
         Service Forms W-8ECI or Forms W-8BEN or such other forms or documents
         (or successor forms or documents), appropriately completed, as may be
         applicable to establish that such Lender (or participant or Assignee
         Lender) is entitled to receive payments under this Agreement without
         deduction or withholding of any United States federal income taxes.

                  The Borrower shall not be required to pay any additional
         amounts to any Lender (or participant or Assignee Lender) in respect of
         Taxes pursuant to this Section 5.6 if the obligation to pay such
         additional amounts would not have arisen but for a failure by such
         Lender (or participant or Assignee Lender) to comply with the
         provisions of this Section 5.6 unless such failure results from (a) a
         change in applicable treaty, law or regulation or interpretation
         thereof or (b) an amendment, modification or revocation of any
         applicable tax treaty or a change in official position regarding the
         application or interpretation thereof, in each case after the date such
         Lender (or participant or Assignee Lender) becomes a party to this
         Agreement.

         SECTION 5.7. Payments, Computations, etc. Unless otherwise expressly
provided, all payments by the Borrower pursuant to this Agreement, the Notes or
any other Loan Document shall be made by the Borrower to the Agent for the pro
rata account of the Lenders entitled to receive such payment. All such payments
required to be made to the Agent shall be made, without setoff, deduction or
counterclaim, not later than 11:00 a.m., San Francisco time, on the date due, in
same day or immediately available funds, to such account as the Agent shall
specify from time to time by notice to the Borrower. Funds received after that
time shall be deemed to have been received by the Agent on the next succeeding
Business Day. The Agent shall promptly remit in same day funds to each Lender
its share, if any, of such payments received by the Agent for the account of
such Lender. All interest and fees shall be computed on the basis of the actual
number of days (including the first day but excluding the last day) occurring
during the period for which such interest or fee is payable over a year
comprised of 360 days (or, in the case of interest on a Base Rate Loan (other
than when calculated with respect to the Federal Funds Rate), 365 days or, if
appropriate, 366 days). Whenever any payment to be made shall otherwise be due
on a day which is not a Business Day, such payment shall (except as otherwise
required by clause (c) of the definition of the term "Interest Period" with
respect to LIBO Rate Loans) be

                                       53

<PAGE>

made on the next succeeding Business Day and such extension of time shall be
included in computing interest and fees, if any, in connection with such
payment.

         SECTION 5.8. Sharing of Payments. If any Lender shall obtain any
payment or other recovery as a result of its receipt of any collateral or
otherwise (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Loan (other than pursuant to the terms of Sections
5.3, 5.4 and 5.5) or Letter of Credit in excess of its pro rata share of
payments then or therewith obtained by all Lenders, such Lender shall purchase
from the other Lenders such participations in Loans made by them and/or Letters
of Credit as shall be necessary to cause such purchasing Lender to share the
excess payment or other recovery ratably with each of them; provided, however,
that if all or any portion of the excess payment or other recovery is thereafter
recovered from such purchasing Lender, the purchase shall be rescinded and each
Lender which has sold a participation to the purchasing Lender shall repay to
the purchasing Lender the purchase price to the ratable extent of such recovery
together with an amount equal to such selling Lender's ratable share (according
to the proportion of (a) the amount of such selling Lender's required repayment
to the purchasing Lender to (b) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. The Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section may, to the fullest extent permitted by law, exercise
all its rights of payment (including pursuant to Section 5.9) with respect to
such participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation. If under any applicable
bankruptcy, insolvency or other similar law, any Lender receives a secured claim
in lieu of a setoff to which this Section applies, such Lender shall, to the
extent practicable, exercise its rights in respect of such secured claim in a
manner consistent with the rights of the Lenders entitled under this Section to
share in the benefits of any recovery on such secured claim.

         SECTION 5.9. Use of Proceeds. The Borrower shall apply the proceeds of
each Borrowing of Revolving Loans to the general corporate purposes of the
Borrower and its Subsidiaries, including Capital Expenditures; Letters of Credit
shall be used for general corporate purposes of the Borrower and its
Subsidiaries (including credit support by the Borrower for gas and power
contracts for CES, Calpine Energy Services Canada Partnership and Calpine Energy
Services UK Limited). The Borrower shall apply the proceeds of the Term B Loans
and of the 2003 Senior Notes and the Second Priority B Loans (a) to repay all
amounts owing under the 2000 Credit Agreement and, except to the extent
continued hereunder, the 2002 Credit Agreement and (b) after application as set
forth in clause (a) above, to general corporate purposes. Without limiting the
foregoing, no Letter of Credit or proceeds of any Loan will be used to (i)
acquire any equity security of a class which is registered pursuant to Section
12 of the Securities Exchange Act of 1934 or any "margin stock", as defined in
F.R.S. Board Regulation U, (ii) finance acquisitions (other than the acquisition
of equipment, sites and property in the ordinary course of the Borrower and its
Subsidiaries' business, but in no event may Loans or Letters of Credit be used
to finance acquisitions of power projects, reserves of geothermal steam and
fluids and natural gas reserves), (iii) make Investments in any third parties
(other than Investments in Subsidiaries), directly or indirectly, through the
Borrower or any of its Subsidiaries or Affiliates, or (iv) defease, repurchase
or prepay any Subordinated Debt or any Senior Notes.

         SECTION 6.2.5. Indentures. (a) The Borrower shall have certified to the
         Agent that its incurrence of the Indebtedness under such Borrowing is
         permitted under the terms of Section 3.4 of the Pre-2000 Indentures. To
         the extent that the Borrower is relying on clause (a) of Section 3.4 of
         the Pre-2000 Indentures, the Borrower shall have delivered to the Agent
         a certificate of an Authorized Officer of the Borrower demonstrating
         its compliance with the incurrence test set forth therein.

                  (b) The Borrower shall have certified to the Agent that the

         terms of Section 3.7 of the Pre-2000 Indentures and Section 3.4 of the

         3.7(d) of the Pre-2000 Indentures in making such analysis and
         certification. To the extent the Borrower is relying on Section
         3.7(f)(1) of each of the Pre-2000 Indentures and on Section 3.4(a)(i)
         of the Shelf Indenture, the Borrower shall have delivered to the Agent

         Pre-2000 Indentures and

                                       58

<PAGE>

         the proviso to Section 3.4 of the Shelf Indenture, the Borrower shall
         have delivered to the Agent a certificate of an Authorized Officer of
         the Borrower demonstrating its compliance with the incurrence tests set
         forth therein.

         SECTION 6.2.6. Solvency. Both before and after giving effect to any

governmental licenses, permits and other approvals to enter into and perform its
Obligations under this Agreement, the Notes and each other Loan Document to

delivery and performance by the Borrower of this Agreement, the Notes and each
other Loan Document executed or to be executed by it, and the execution,

to be executed by it are within the Borrower's and each such Obligor's corporate
powers, have been duly authorized by all necessary corporate action, and do not

                  (a) contravene the Borrower's or any such Obligor's Organic
         Documents;

                  (b) contravene any contractual restriction (including, without
         limitation, the Senior Note Indentures), law or governmental regulation

         Closing Date by the Borrower, the Borrower shall promptly (i) execute
         and deliver to the Collateral Trustee such amendments to the Security

         avoidance of doubt, any capital stock of CES) and (B) the aggregate
         Fair Market Value of the CES Assets subject to all such Asset Sales and
         Monetizations, together with the aggregate outstanding principal amount
         of Non-Recourse Debt of CES incurred under Section 8.2.2(m), shall not
         exceed $500,000,000 during the term of this Agreement; (vi) in the case
         of any assets sold, transferred, leased, contributed or conveyed by the
         Borrower or any Subsidiary of the Borrower organized under the laws of
         the United States (or any State thereof, including the District of
         Columbia) to any Subsidiary of the Borrower organized under the laws of
         Canada or any province or territory thereof, the aggregate Fair Market
         Value of all such assets shall not exceed $100,000,000; and (vii) all
         prepayments required in respect thereof pursuant to Sections 2.2.2 and

not consent to any amendment, supplement or other modification of any of the
terms or provisions contained in, or applicable to, any Restricted Capital
described in clause (i) of the definition thereof, or any document or instrument
evidencing or applicable thereto, other than (i) any amendment, supplement or
other modification which (A) extends the date or reduces the amount of any
required repayment or redemption or (B) cures any ambiguity, omission, defect or
inconsistency therein or in any documentation under which such Restricted
Capital is issued or incurred so long as such a cure is not adverse to the
interests of the Lenders or (ii) any other change that is not adverse to the
interests of the Lenders or that has been approved by the Required Lenders.

         SECTION 8.2.12. Transactions with Affiliates. Except for transactions
between the Borrower and its Wholly Owned Subsidiaries or Cogen America or

<PAGE>

Subsidiary and another Wholly Owned Subsidiary or Cogen America, the Borrower
will not, and will not permit any of its Subsidiaries to, enter into, or cause,
suffer or permit to exist any arrangement or contract with any of its other
Affiliates unless such arrangement or contract is fair and equitable to the
Borrower or such Subsidiary and is an arrangement or contract of the kind which
would be entered into by a prudent Person in the position of the Borrower or
such Subsidiary with a Person which is not one of its Affiliates.

         SECTION 8.2.13. Negative Pledges, Restrictive Agreements, etc. The
Borrower will not, and will not permit any of its Subsidiaries to, enter into
any agreement which:

                           (i)      prohibits the creation or assumption of any
                  Lien upon its properties, revenues or assets, whether now
                  owned or hereafter acquired, or the ability of the Borrower or
                  any other Obligor to amend or otherwise modify this Agreement
                  or any other Loan Document; or

                           (ii)     restricts the ability of any Subsidiary to
                  make any payments, directly or indirectly, to the Borrower by
                  way of dividends, advances, repayments of loans or advances,
                  reimbursements of management and other intercompany charges,
                  expenses and accruals or other returns on investments, or
                  restricts the ability of any such Subsidiary to make any
                  payment, directly or indirectly, to the Borrower;

provided, however, that the above restriction shall not be applicable to (A)
this Agreement or any other Loan Document; (B) any agreement governing
Indebtedness permitted under Section 8.2.2(a), (b), (e), (f), (g), (j) (provided
that the Borrower has delivered to the Agent a certificate of an Authorized
Officer of the Borrower certifying that the provision contained in such
agreement, which would otherwise cause such agreement to violate this Section
8.2.13, (I) is required in order to enter into such agreement, (II) is customary
for such agreements and (III) applies only to the Person entering into such
agreement and its Subsidiaries), (l), (m), (o) (provided that any such
agreement, but for this proviso, would violate only clause (i) of this Section
8.2.13) or (p) (and refinancings, extensions and renewals of such Indebtedness
permitted under Section 8.2.2(r)); (C) any agreement in respect of a
Sale/Leaseback Transaction permitted under Section 8.2.3(m); or (D) any
agreement pursuant to which any preferred equity shall be issued (provided that
the provision contained in such agreement, which would otherwise cause such
agreement to violate this Section 8.2.13, restricts only the right of the issuer
of such preferred equity to pay dividends on the common equity of such issuer
while any arrearage exists in the payment of dividends on such preferred
equity).

         SECTION 8.2.14. Amendments to Canadian Documentation. The Borrower will
not, and will not permit CCEC, CCEF or QCH, to amend the contractual
arrangements among CCEC, QCH and CCEF in respect of the term debentures dated
April 25, 2001, August 14, 2001 and August 23, 2001 between CCEC and CCEF and
the documentation executed in connection therewith or the memorandum of
association or articles of association of CCEC without the prior written consent
of the Agent and the Arrangers, which consent shall not be unreasonably withheld
or delayed. The Borrower will not permit any amendments to be made to the
articles of incorporation of any Guarantor without the prior written consent of
the Agent and the Arrangers, which consent shall not be unreasonably withheld or
delayed. Nothing in this Section 8.2.14

                                       81

<PAGE>

shall, however, be deemed to limit the ability of any one or more of QM, JOQ or
QCH to merge or consolidate with one or more of the others (subject only to a
delivery of a certificate in a form reasonably satisfactory to the Agent to the
effect that the merged entity would not be liable for any Obligations of CCEF).

         SECTION 8.2.15. Restrictions on Issuance of Preferred Equity. No
Subsidiary of the Borrower shall issue any preferred or preference capital stock
or other capital stock with rights prior to or in addition to those contained in
common equity, other than any such equity issued by a Subsidiary of the Borrower
(other than a Subsidiary that owns, directly or indirectly, any Material
Designated Assets), the net proceeds of which are applied to finance the
exploration, drilling, development, construction or purchase of or by, or
repairs or improvements or additions to, property or assets of the Borrower or
any Subsidiary.

         SECTION 8.3. No Restriction on Payments to the Borrower. Nothing herein
shall restrict the ability of any Subsidiary of the Borrower to make any payment
by way of dividends, advances, repayments of loans or advances, reimbursements
of management and other intercompany charges, expenses and accruals or other
returns on investments or any other payment, directly or indirectly, to the
Borrower.

of five days) in the payment when due of interest on any Loan, any fee or of any
other Obligation.

         SECTION 9.1.2. Breach of Warranty. Any representation or warranty of
the Borrower or any other Obligor made or deemed to be made hereunder or in any

<PAGE>

period of 30 days after notice thereof shall have been given to the Borrower by
the Agent or any Lender (or such longer period as the Required Lenders in their
discretion, may agree, provided that such Obligor has commenced such cure within
such 30 day period and thereafter diligently pursues such cure to completion).

         SECTION 9.1.5. Default on Other Indebtedness. (a) A default shall occur
in the payment when due (subject to any applicable grace period), whether by
acceleration or otherwise, of any Indebtedness (other than Indebtedness
described in Section 9.1.1) of the Borrower or any of its Significant
Subsidiaries or any other Obligor having a principal amount, individually or in
the aggregate, in excess of $10,000,000, (b) a default shall occur in the
performance or observance of any obligation or condition with respect to such
Indebtedness if the effect of such default is to accelerate the maturity of any
such Indebtedness or, in the case of the Borrower only, such default shall
continue unremedied for any applicable period of time sufficient to permit the
holder or holders of such Indebtedness, or any trustee or agent for such
holders, to cause such Indebtedness to become due and payable prior to its
expressed maturity (and notice of such default has been given to the relevant
borrower), (c) a default shall occur in the performance or observance of any
obligation or condition with respect to the Borrower's debt securities issued to
a Trust or to any Indebtedness of any Significant Subsidiary (other than CCFCI

$10,000,000, and, as a result thereof, the holder or holders of such debt
securities or such Indebtedness, or any trustee or agent for such holders,
causes such securities or Indebtedness to be repaid more quickly than
theretofore scheduled, whether through the introduction of a "cash sweep," the
increase of an existing "cash sweep" or otherwise, or (d) a default of a type
described in clause (b) above shall occur with respect to any Indebtedness of
CCFCI or CCFCII having an unpaid principal amount in excess of $10,000,000
(whether or not such default actually results in the acceleration of the
applicable Indebtedness) and, as a result thereof, the holder or holders of such
debt securities or such Indebtedness, or any trustee or agent for such holders,
causes such securities or Indebtedness to be repaid more quickly than
theretofore scheduled, whether through the introduction of a "cash sweep," the
increase of an existing "cash sweep" or otherwise.

         SECTION 9.1.6. Judgments. Any final judgment or order (not covered by
insurance) for the payment of money shall be rendered against the Borrower or
any Significant Subsidiary or any other Obligor in an amount in excess of
$25,000,000 (or its foreign currency equivalent) (treating any deductibles,
self-insurance or retention as not so covered) which is not stayed or discharged
within 30 days after entry of such final judgment or order, and there shall be
any period of more than 30 consecutive days following entry of the final
judgment or order in excess of $25,000,000 (or its foreign currency equivalent)
during which a stay of enforcement of such final judgment or order, by reason of
a pending appeal or otherwise, shall not be in effect.

         SECTION 9.1.7. Pension Plans. Any of the following events shall occur
with respect to any Pension Plan

                  (a) the institution of any steps by the Borrower, any member
         of its Controlled Group or any other Person to terminate a Pension Plan
         if, as a result of such termination, the Borrower or any such member
         could be required to make a contribution to such

                                       83

<PAGE>

         Pension Plan, or could reasonably expect to incur a liability or

occur.

         SECTION 9.1.9. Bankruptcy, Insolvency, etc. The Borrower or any of its

                  (b) apply for, consent to, or acquiesce in, the appointment of
         a trustee, receiver, sequestrator or other custodian for the Borrower
         or any of its Significant Subsidiaries or any other Obligor or any
         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,

         part of the property of any thereof, and such trustee, receiver,
         sequestrator or other custodian shall not be discharged within 60 days,
         provided that the Borrower, each Significant Subsidiary and each other
         Obligor hereby expressly authorizes the 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

         of its Significant Subsidiaries or any other Obligor, and, if any such
         case or proceeding is not commenced by the Borrower or such Significant
         Subsidiary or such other Obligor, such case or proceeding shall be
         consented to or acquiesced in by the Borrower or such Significant
         Subsidiary or such other Obligor or shall result in the entry of an
         order for relief or shall remain for 60 days undismissed, provided that
         the Borrower, each Significant Subsidiary and each other Obligor hereby
         expressly authorizes the 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 action authorizing any of the foregoing.

         SECTION 9.1.10. Impairment of Security, etc. Any Loan Document, or any
Lien granted thereunder, shall (except in accordance with its terms), in whole
or in part, terminate, cease to be effective or cease to be the legally valid,
binding and enforceable obligation of any Obligor party thereto; or the
Borrower, any other Obligor or any Subsidiary shall, directly or indirectly,
contest in any manner such effectiveness, validity, binding nature or
enforceability; or

                                       84

<PAGE>

any Lien securing any Obligation shall, in whole or in part, cease to be a
perfected first priority Lien, subject only to those exceptions expressly
permitted by such Loan Document.

         SECTION 9.2. Action if Bankruptcy. If any Event of Default described in

principal amount of all outstanding Loans and all other Obligations shall
automatically be and become immediately due and payable, without notice or
demand.

         SECTION 9.3. Action if Other Event of Default. If any Event of Default
(other than any Event of Default described in clauses (a) through (d) of Section
9.1.9 with respect to the Borrower or any Significant Subsidiary or any other
Obligor) shall occur for any reason, whether voluntary or involuntary, and be
continuing, the Agent, upon the direction of the Required Lenders, shall by
notice to the Borrower declare all or any portion of the outstanding principal
amount of the Loans and other Obligations to be due and payable and/or the
Commitments (if not theretofore terminated) to be terminated, whereupon the full
unpaid amount of such Loans and other Obligations which shall be so declared due
and payable shall be and become immediately due and payable, without further
notice, demand or presentment, and/or, as the case may be, the Commitments shall
terminate and the Agent may thereupon exercise any and all remedies available
under the Loan Documents and applicable law.

                                   ARTICLE X

                                    THE AGENT

         SECTION 10.1. Actions. Each Lender hereby appoints Scotia Capital as
its Agent under and for purposes of this Agreement, the Notes and each other
Loan Document. Each Lender authorizes the Agent to act on behalf of such Lender
under this Agreement, the Notes and each other Loan Document and, in the absence
of other written instructions from the Required Lenders received from time to
time by such Person (with respect to which such Person agrees that it will
comply, except as otherwise provided in this Section or as otherwise advised by
counsel), to exercise such powers hereunder and thereunder as are specifically
delegated to or required of the Agent by the terms hereof and thereof, together
with such powers as may be reasonably incidental thereto. Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement)
the Agent and the Arrangers, pro rata according to such Lender's Aggregate
Percentage, from and against any and all liabilities, obligations, losses,
damages, claims, costs or expenses of any kind or nature whatsoever which may at
any time be imposed on, incurred by, or asserted against, the Agent or any
Arranger in any way relating to or arising out of this Agreement, the Notes and
any other Loan Document, including reasonable attorneys' fees, and as to which
the Agent or any Arranger is not reimbursed by the Borrower; provided, however,
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, claims, costs or expenses which are
determined by a court of competent jurisdiction in a final proceeding to have
resulted from the Agent's or any Arranger's, as the case may be, gross
negligence or willful misconduct. The Agent and the Arrangers shall not be
required to take any action hereunder, under the Notes or under any other Loan
Document, or to prosecute or defend any suit in respect of this Agreement, the
Notes or

                                       85

<PAGE>

any other Loan Document, unless they are indemnified hereunder to its
satisfaction. If any indemnity in favor of the Agent or any Arranger shall be or
become, in such Person's determination, inadequate, such Person may call for
additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

         SECTION 10.2. Funding Reliance, etc. Unless the Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m., San
Francisco time, on the day prior to a Borrowing that such Lender will not make
available the amount which would constitute its applicable Percentage of such
Borrowing on the date specified therefor, the Agent may assume that such Lender
has made such amount available to the Agent and, in reliance upon such
assumption, make available to the Borrower a corresponding amount. If and to the
extent that such Lender shall not have made such amount available to the Agent,
such Lender and the Borrower severally agree to repay the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date the Agent made such amount available to the Borrower to the date
such amount is repaid to the Agent, at the interest rate applicable at the time
to Loans comprising such Borrowing.

         SECTION 10.3. Exculpation. Neither the Agent nor any of their
respective directors, officers, employees or agents shall be liable to any
Lender for any action taken or omitted to be taken by it under this Agreement or
any other Loan Document, or in connection herewith or therewith, except for its
own willful misconduct or gross negligence, nor responsible for any recitals or
warranties herein or therein, nor for the effectiveness, enforceability,
validity or due execution of this Agreement or any other Loan Document, nor for
the creation, perfection or priority of any Liens purported to be created by any
of the Loan Documents, or the validity, genuineness, enforceability, existence,
value or sufficiency of any collateral security, nor to make any inquiry
respecting the performance by the Borrower of its obligations hereunder or under
any other Loan Document. Any such inquiry which may be made by the Agent shall
not obligate it to make any further inquiry or to take any action. The Agent
shall be entitled to rely upon advice of counsel concerning legal matters and
upon any notice, consent, certificate, statement or writing which it believes to
be genuine and to have been presented by a proper Person.

         SECTION 10.4. Successor. The Agent may resign as such at any time upon
at least 30 days' prior notice to the Borrower and all Lenders. If the Agent at
any time shall resign, the Required Lenders may appoint another Lender as a
successor thereto which shall thereupon become the Agent, as applicable,
hereunder. If no successor shall have been so appointed by the Required Lenders,
and shall have accepted such appointment, within 30 days after the retiring
Agent's giving notice of resignation, then the retiring Person may, on behalf of
the Lenders, appoint a successor, which shall be one of the Lenders or a
commercial banking institution organized under the laws of the U.S. (or any
State thereof) or a U.S. branch or agency of a commercial banking institution,
and having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor shall be entitled to receive from the retiring Agent such documents of
transfer and assignment as such successor may reasonably request, and shall
thereupon succeed to and become vested with all rights, powers, privileges and
duties of the retiring Agent, as applicable, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring Agent's resignation hereunder as the Agent, the provisions of

                                       86

<PAGE>

                  (a) this Article X shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was the Agent under
         this Agreement; and

                  (b) Section 11.3 (with respect to expenses incurred prior to
         resignation) and Section 11.4 shall continue to inure to its benefit.

         SECTION 10.5. Loans or Letters of Credit Issued by Agent or any Issuer.

                  (a) The Agent shall have the same rights and powers with
         respect to (x) the Loans made by it or any of its Affiliates, (y) the
         Notes held by it or any of its Affiliates, and (z) its participating
         interests in the Letters of Credit as any other Lender and may exercise
         the same as if it were not the Agent. The Agent and its Affiliates may
         accept deposits from, lend money to, and generally engage in any kind
         of business with the Borrower or any Subsidiary or Affiliate of the
         Borrower as if such Person were not the Agent hereunder.

                  (b) Each Issuer shall have the same rights and powers with
         respect to (x) the Loans made by it or any of its Affiliates, (y) the
         Notes held by it or any of its Affiliates, and (z) its participating
         interests in the Letters of Credit as any other Lender and may exercise
         the same as if it were not an Issuer. Each Issuer and its Affiliates
         may accept deposits from, lend money to, and generally engage in any
         kind of business with the Borrower or any Subsidiary or Affiliate of
         the Borrower as if it were not an Issuer hereunder.

         SECTION 10.6. Credit Decisions. Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrower, this Agreement, the other
Loan Documents (the terms and provisions of which being satisfactory to such
Lender) and such other documents, information and investigations as such Lender
has deemed appropriate, made its own credit decision to extend its Commitments.
Each Lender also acknowledges that it will, independently of the Agent and each
other Lender, and based on such other documents, information and investigations
as it shall deem appropriate at any time, continue to make its own credit
decisions as to exercising or not exercising from time to time any rights and
privileges available to it under this Agreement or any other Loan Document.

         SECTION 10.7. Copies, etc. The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the Agent
by the Borrower pursuant to the terms of this Agreement (unless concurrently
delivered to the Lenders by the Borrower). The Agent will distribute to each
Lender each document or instrument received for its account and copies of all
other communications received by the Agent from the Borrower for distribution to
the Lenders by the Agent in accordance with the terms of this Agreement.

         SECTION 10.8. Other Agents; Lead Arrangers. None of the Lenders
identified on the facing page or signature pages of this Agreement as a
"bookrunner," or "lead arranger" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those
applicable to all Lenders as such. Without limiting the foregoing, none of the
Lenders so identified shall have or be deemed to have any fiduciary relationship
with any Lender. Each

                                       87

<PAGE>

Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders so identified in deciding to enter into this Agreement or in taking or
not taking action hereunder.

         SECTION 10.9. Collateral Matters.

                  (a) Each of the Lenders hereby acknowledges and agrees that
         Liens upon the Collateral granted to or held by the Agent or the
         Collateral Trustee under any Loan Document will be released:

                           (i)      in whole, upon termination of the Revolving
                  Loan Commitments and payment in full of all Obligations (other
                  than contingent indemnification obligations) and the
                  expiration or termination of all Letters of Credit;

                           (ii)     as to any Collateral that is sold,

                  other disposition permitted under Sections 8.2.9 or 8.2.10

                  otherwise) to any Subsidiary of the Borrower permitted under
                  Sections 8.2.9 or 8.2.10; provided, however, that if any
                  Pledged Power Project is transferred from the Borrower to a
                  Subsidiary that is a Pledged Entity or a Subsidiary of a
                  Pledged Entity, the Lien created by the applicable Security
                  Document thereon shall be so released);

                           (iii)    in connection with any abandonment,
                  forfeiture, surrender or release of oil and gas assets
                  permitted under the Deeds of Trust;

                           (iv)     as to any Excluded Assets; and

                           (v)      to the extent permitted by Section 11.1(f).

                  (b) Each Lender hereby authorizes the Agent to act under the
         Collateral Trust Agreement to release the Collateral Trustee's Lien on
         applicable Collateral to the extent set forth in clause (a) above.

                  (c) Each Lender hereby authorizes and directs the Agent to
         transfer to the Collateral Trustee all Liens and security interests
         held by the Agent under the 2002 Credit Agreement, including the
         Agent's interest as beneficiary or mortgagee under the Existing Deeds
         of Trust, its interest as secured party under related financing
         statements and all rights, powers, duties and obligations under the
         Existing Deeds of Trust necessary or helpful in the exercise of the
         Collateral Trustee's duties and obligations under the Collateral Trust
         Agreement.

                  (d) The Borrower agrees that, in the case of any Lien to be
         released in connection with a proposed sale, transfer or other
         disposition pursuant to clause (a)(ii) above, (i) such release will
         only become effective in connection with a Permitted Sale, (ii) no Lien
         on such property has or will be granted to any other Person other than
         the Collateral Trustee (for the benefit of, among others, the Lenders
         hereunder) during the period between the date of such release and the
         date of the consummation of the Permitted Sale and (iii) in

                                       88

<PAGE>

         the event that the consummation of the Permitted Sale does not take
         place (or a definitive binding agreement with respect to such Permitted
         Sale is not entered into) with 60 days of such release, the Lien of the
         Collateral Trustee (for the benefit of, among others, the Lenders
         hereunder) on such property will immediately and automatically be
         reinstated.

consent of any Term B Lender and (b) none of the matters referred to in clauses
(d)(i)(B) or (d)(ii) of the immediately preceding proviso shall require the
consent of any Revolving Lender.

Notwithstanding the foregoing, Section 10.3 shall not be amended without the

or the holder of any Note in exercising any power or right under this Agreement
or any other Loan Document shall operate as a waiver thereof, nor shall any

         administration of this Agreement and of each other Loan Document,
         including schedules and exhibits, and any amendments, waivers,
         consents, supplements or other modifications to this Agreement or any
         other Loan Document as may from time to time hereafter be required,

                  (c) the preparation and review of the form of any document or
         instrument relevant to this Agreement or any other Loan Document.

If the Agent or its counsel shall be precluded from undertaking the duties
described in clause (b) above due to a conflict of interest, the Lenders may
appoint another Lender and/or counsel to discharge such duties and the Borrower
shall be responsible for the reasonable expenses of such Lender and counsel. The
Borrower further agrees to pay, and to save the Agent, each Issuer and the
Lenders harmless from all liability for, any stamp or other taxes (other than
income taxes) which may be payable in connection with the execution or delivery
of this Agreement, the borrowings hereunder, the issuance of the Notes, the
issuance of the Letters of Credit, or any other Loan Documents. The Borrower
also agrees to reimburse the Agent, each Issuer and each Lender upon demand for
all reasonable out-of-pocket expenses (including attorneys' fees and legal
expenses) incurred by the Agent or such Lender in connection with (x) the
negotiation of any restructuring or "work-out", whether or not consummated, of
any Obligations and (y) the enforcement of any Obligations upon and during the
continuing of an Event of Default.

the Issuers and each Lender and each of their respective Affiliates, officers,
directors, employees and agents, and each other person controlling any of the
foregoing within the meaning of either Section 15 of the Securities Act of 1933,
as amended, or Section 20 of the Securities Exchange Act of 1934, as amended
(collectively, the "Indemnified Parties") free and harmless from and against any
and all actions, causes of action, suits, losses, costs, claims, liabilities and
damages, and expenses incurred by any Indemnified Party in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action for
which indemnification hereunder is sought), including reasonable attorneys' fees
and disbursements (collectively, the "Indemnified Liabilities"), incurred by the
Indemnified Parties or any of them as a result of, or arising out of, or
relating to

                  (a) any transaction financed or to be financed in whole or in
         part, directly or indirectly, with the proceeds of any Loan or the use
         of any Letter of Credit;

                  (b) the entering into and performance of this Agreement and
         any other Loan Document by any of the Indemnified Parties (including
         any action brought by or on behalf of the Borrower as the result of the
         Required Lenders' refusal to make any Credit Extension as a result of
         the Borrower's failure to satisfy the conditions in Article VI

                                       91

<PAGE>

         hereof but not including any breach of this Agreement or any other Loan
         Document by the Agent or any of the Lenders);

                  (c) any investigation, litigation or proceeding related to any
         acquisition or proposed acquisition by the Borrower or any of its
         Subsidiaries of all or any portion of the stock or assets of any
         Person, whether or not the Agent or such Lender is party thereto;

                  (d) any investigation, litigation or proceeding related to any
         environmental cleanup, audit, compliance or other matter relating to
         the protection of the environment or the Release by the Borrower or any
         of its Subsidiaries of any Hazardous Material; or

                  (e) the presence on or under, or the escape, seepage, leakage,
         spillage, discharge, emission, discharging or releases from, any real
         property owned or operated by the Borrower or any Subsidiary thereof of
         any Hazardous Material (including any losses, liabilities, damages,
         injuries, costs, expenses or claims asserted or arising under any
         Environmental Law), regardless of whether caused by, or within the
         control of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities resulting from, arising out of or
relating to the relevant Indemnified Party's gross negligence or willful
misconduct. If and to the extent that the foregoing undertaking may be
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. In addition to the
foregoing, the Borrower hereby waives any and all rights to seek or obtain
consequential damages from any Indemnified Party.

         The Lenders agree to indemnify each Issuer with respect to any acts
taken or omissions suffered by the Issuer in connection with each Letter of
Credit issued by it or proposed to be issued by it and the related Issuance
Request (to the extent not reimbursed by the Borrower), ratably according to
their respective Aggregate Percentages, from and against any and all claims,
damages, losses, liabilities and expenses (including without limitation,
reasonable fees and disbursements of counsel) of any kind or nature whatsoever
which may be imposed on, incurred by, or asserted against any Issuer in any way
relating to or arising out of any of the Loan Documents or the Letters of Credit
or any action taken or omitted by such Issuer under the Loan Documents or the
Letters of Credit (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY
OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF THE
ISSUER, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY OR EXPENSE
ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE ISSUER). IT IS
THE INTENT OF THE PARTIES HERETO THAT THE ISSUER SHALL, TO THE EXTENT PROVIDED
IN THIS SECTION 11.4, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY
NEGLIGENCE. Without limitation of the foregoing, each Lender agrees to reimburse
each Issuer promptly upon demand for such Lender's ratable share of any
reasonable out-of-pocket expenses (including reasonable counsel fees) incurred
by such Issuer in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in

                                       92

<PAGE>

respect of rights or responsibilities under, the Loan Documents or the Letters
of Credit, or any of them, to the extent that the Issuer is not reimbursed for
such expenses by the Borrower.

         SECTION 11.5. Survival. The obligations of the Borrower under Sections
5.3, 5.4, 5.5, 5.6, 11.3 and 11.4, and the obligations of the Lenders under
Section 10.1, shall in each case survive any termination of this Agreement, the
payment in full of all Obligations and the termination of all Commitments. The
representations and warranties made by each Obligor in this Agreement and in
each other Loan Document shall survive the execution and delivery of this
Agreement and each such other Loan Document.

         SECTION 11.6. Severability. Any provision of this Agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such provision and such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions of this Agreement or such Loan Document or affecting the validity or
enforceability of such provision in any other jurisdiction.

         SECTION 11.7. Headings. The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not affect
the meaning or interpretation of this Agreement or such other Loan Document or
any provisions hereof or thereof.

         SECTION 11.8. Execution in Counterparts, Effectiveness, etc. This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be executed by the Borrower and the Agent and be deemed to be an
original and all of which shall constitute together but one and the same
agreement. This Agreement shall become effective when counterparts hereof
executed on behalf of the Borrower and each Lender (or notice thereof
satisfactory to the Agent) shall have been received by the Agent, and the
conditions precedent set forth in Section 6.1 shall have been satisfied.

         SECTION 11.9. Governing Law; Entire Agreement. THIS AGREEMENT, THE
NOTES AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE
UNDER AND GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE
STATE OF NEW YORK. This Agreement, the Notes and the other Loan Documents
constitute the entire understanding among the parties hereto with respect to the
subject matter hereof and supersede any prior agreements, written or oral, with
respect thereto.

         SECTION 11.10. Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that:

                  (a) the Borrower may not assign or transfer its rights or
         obligations hereunder without the prior written consent of the Agent
         and all Lenders; and

                  (b) the rights of sale, assignment and transfer of the Lenders

         other financial institutions; provided that, in addition to the consent
         of the Agent as set forth above, only notice to and not the consent of

                  shall have been given to the Borrower and the Agent by such
                  Lender and such Assignee Lender,

a party hereto and to the extent that rights and obligations hereunder have been
assigned and delegated to such Assignee Lender in connection with such Lender
Assignment Agreement, shall have the rights and obligations of a Lender

the extent that rights and obligations hereunder have been assigned and
delegated by it in connection with such Lender Assignment Agreement, shall be
released from its obligations hereunder and under the other Loan Documents with
respect to obligations arising after the date of assignment. Within five
Business Days after its receipt of notice that the Agent has received an
executed Lender Assignment Agreement, the Borrower shall, if requested by the
Assignee Lender, execute and deliver to the Agent (for delivery to the relevant
Assignee Lender) new Notes evidencing such Assignee Lender's assigned Loans and
Commitments and, if the assignor Lender has retained Loans and Commitments
hereunder, replacement Notes in the principal amount of the Loans and
Commitments retained by the assignor Lender hereunder (such Notes to be in
exchange for, but not in payment of, those Notes then held by such assignor
Lender). Each such Note shall be dated the date of the predecessor Notes. The
assignor Lender shall mark the predecessor Notes "exchanged" and deliver them to
the Borrower. Such assignor Lender or such Assignee Lender must also pay a
processing fee to the Agent upon delivery of any Lender Assignment Agreement in
the amount of $3,000. Any attempted assignment and delegation not made in
accordance with this Section 11.11.1 shall be null and void. In addition to the
foregoing, and notwithstanding any other provision hereof, (i) any Lender may at
any time without notice to or consent by any other Person assign its rights
under this Agreement to any Federal Reserve Bank and (ii) the Agent shall
provide notice to the Lenders of any assignments by it under this Section
11.11.1.

         SECTION 11.11.2. Participations. Any Lender may at any time sell to one
or more commercial banks or other Persons (each of such commercial banks and
other Persons being herein called a "Participant") participating interests (or a
sub-participating interest, in the case of a Lender's participating interest in
a Letter of Credit) in any of the Loans, Commitments, or other interests of such
Lender hereunder; provided, however, that

                  (a) no participation or sub-participation contemplated in this
         Section 11.11 shall relieve such Lender from its Commitments or its
         other obligations hereunder or under any other Loan Document,

                                       95

<PAGE>

                  (b) such Lender shall remain solely responsible for the
         performance of its Commitments and such other obligations,

                  (c) the Borrower and each other Obligor and the Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Agreement and each
         of the other Loan Documents,

                  (d) no Participant, unless such Participant is an Affiliate of
         such Lender, or is itself a Lender, shall be entitled to require such
         Lender to take or refrain from taking any action hereunder or under any
         other Loan Document, except that such Lender may agree with any
         Participant that such Lender will not, without such Participant's
         consent, take any actions of the type described in clause (b) of
         Section 11.1, and

                  (e) the Borrower shall not be required to pay any amount under
         Section 5.6 that is greater than the amount which it would have been
         required to pay had no participating interest been sold.

The Borrower acknowledges and agrees that each Participant, for purposes of
Sections 5.3, 5.4, 5.5, 5.6, 5.8, 5.9, 11.3 and 11.4, shall be considered a
Lender.

         SECTION 11.11.3. Special Funding Vehicles. Notwithstanding anything to
the contrary contained herein, any Lender (a "Granting Lender") may grant to a
special purpose funding vehicle (a "SPC"), identified as such in writing from
time to time by the Granting Lender to the Agent and the Borrower, the option to
provide to the Borrower all or any part of any Loan that such Granting Lender is
obligated to make to the Borrower pursuant to this Agreement; provided that (i)
nothing herein shall constitute a commitment by any SPC to make any Loan, (ii)
if an SPC elects not to exercise such option or otherwise fails to provide all
or any part of such Loan, the Granting Lender shall remain obligated to make
such Loan pursuant to the terms hereof, (iii) the Borrower shall not be required
to pay any amount under Section 5.6 that is greater than the amount which it
would have been required to pay had there been no grant to an SPC and any SPC
(or assignee of an SPC) will comply, if applicable, with the provisions
contained in Section 5.6. No grant by any Granting Lender to an SPC agreeing to
provide a Loan or making of such Loan by any SPC shall operate to relieve such
Granting Lender of its liabilities and obligations hereunder, except to the
extent of the making of such Loan by such SPC. The making of a Loan by an SPC
hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Loan were made by such Granting Lender. Each party
hereto hereby agrees that no SPC shall be liable for any indemnity or similar
payment obligation under this Agreement (all liability for which shall remain
with the Granting Lender). In addition, each party hereto hereby agrees (which
agreement shall survive the termination of this Agreement) that, any SPC may (i)
with notice to, but without the prior written consent of, the Borrower and the
Agent and without paying any processing fee therefor, assign all or a portion of
its interests in any Loans to the Granting Lender or to any financial
institutions (consented to by the Borrower and the Agent, each in its sole
discretion) providing liquidity and/or credit support to or for the account of
such SPC to support the funding or maintenance of Loans and (ii) disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of any surety, guarantee or
credit or liquidity enhancement to such SPC. This Section may not be amended
without the written consent of any SPC that

                                       96

<PAGE>

holds an option to provide Loans. No recourse under any obligation, covenant, or
agreement of the SPC contained in this Agreement shall be had against any
shareholder, officer, agent or director of the SPC as such, by the enforcement
of any assessment or by any proceeding, by virtue of any statute or otherwise;
it being expressly agreed and understood that this Agreement is a corporate
obligation of the SPC and no personal liability shall attach to or be incurred
by any officer, agents or member of the SPC as such, or any of them under or by
reason of any of the obligations, covenants or agreements of the SPC contained
in this Agreement, or implied therefrom, and that any and all personal liability
for breaches by the SPC of any such obligations, covenants or agreements, either
at law or by statute or constitution, of every such shareholder, officer, agent
or director is hereby expressly waived by all parties to this Agreement as a
condition of and consideration for the SPC entering into this Agreement;
provided, however, that the foregoing shall not relieve any such person or
entity of any liability they might otherwise have as a result of fraudulent
actions or omissions taken by them. All parties to this Agreement acknowledge
and agree that the SPC shall only be liable for any claims that each of them may
have against the SPC only to the extent of the SPC's assets. The provisions of
this clause shall survive the termination of this Agreement.

         SECTION 11.12. Other Transactions. Nothing contained herein shall
preclude the Agent or any other Lender from engaging in any transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Affiliates in which the Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

         SECTION 11.13. Forum Selection and Consent to Jurisdiction. ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE
LENDERS OR THE BORROWER SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE
COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE
AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER
PROPERTY MAY BE FOUND. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND OF THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH
LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION. THE BORROWER FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY PERSONAL SERVICE WITHIN OR
WITHOUT THE STATE OF NEW YORK OR IN ANY MANNER PROVIDED BY LAW. THE BORROWER
HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF
ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM
THAT ANY SUCH

                                       97

<PAGE>

LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT THE
BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY
COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT
PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN
RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

         SECTION 11.14. Waiver of Jury Trial. THE AGENT, THE LENDERS AND THE
BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION AMONG ANY OF THE AGENT,
THE LENDERS AND THE BORROWER BASED HEREON, OR ARISING OUT OF, UNDER, OR IN
CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF
THE AGENT, THE LENDERS OR THE BORROWER. THE BORROWER ACKNOWLEDGES AND AGREES
THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND
EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND
THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENT AND THE LENDERS
ENTERING INTO THIS AGREEMENT AND EACH SUCH OTHER LOAN DOCUMENT.

         SECTION 11.15. Confidentiality. The Lenders shall hold all non-public
information (which has been identified as such by the Borrower) obtained
pursuant to the requirements of this Agreement in accordance with their
customary procedures for handling confidential information of this nature and in
accordance with safe and sound banking practices and in any event may make
disclosure to any of their examiners, their Affiliates, outside auditors,
counsel and other professional advisors in connection with this Agreement or as
reasonably required by any bona fide transferee, participant or assignee or as
required or requested by any governmental agency or representative thereof or
pursuant to legal process; provided, however, that

                  (a) unless specifically prohibited by applicable law or court
         order, each Lender shall notify the Borrower of any request by any
         governmental agency or representative thereof (other than any such
         request in connection with an examination of the financial condition of
         such Lender by such governmental agency) for disclosure of any such
         non-public information prior to disclosure of such information;

                  (b) prior to any such disclosure pursuant to this Section
         11.15, each Lender shall require any such bona fide transferee,
         participant and assignee receiving a disclosure of non-public
         information to agree in writing

                           (i)      to be bound by this Section 11.15;

                                       98

<PAGE>

                           (ii)     to require such Person to require any other
                  Person to whom such Person discloses such non-public
                  information to be similarly bound by this Section 11.15;

                  (c) except as may be required by an order of a court of
         competent jurisdiction and to the extent set forth therein, no Lender
         shall be obligated or required to return any materials furnished by the
         Borrower or any Subsidiary; and

                  (d) to any direct or indirect contractual counterparty in swap
         agreements or to such contractual counterparty's advisor (so long as
         such contractual counterparty or advisor agrees to be bound by the
         provisions of this Section 11.15).

Notwithstanding anything herein to the contrary, the parties to this Agreement
(and their employees, representatives or other agents) may disclose to any and
all persons, without limitation of any kind, the U.S. federal income tax
treatment and tax structure of the transactions contemplated by this Agreement
and all materials of any kind (including opinions or other tax analyses)
relating to such tax treatment and tax structure. However, no such party shall
disclose any information relating to such tax treatment or tax structure to the
extent nondisclosure is reasonably necessary in order to comply with applicable
securities laws. For this purpose, "tax structure" is limited to facts relevant
to the U.S. federal income tax treatment of the transactions contemplated by
this Agreement and does not include information relating to the identity of the
Borrower, its affiliates, agents or advisors.

         SECTION 11.16. Judgment Currency. The Obligations of the Borrower and
any other Obligor in respect of any sum due to any Lender or the Agent
hereunder, under the Notes or under or in respect of any other Loan Document
shall, notwithstanding any judgment in a currency (the "Judgment Currency")
other than the currency in which such sum was originally denominated (the
"Original Currency"), be discharged only to the extent that on the Business Day
following receipt by such Lender or the Agent of any sum adjudged to be so due
in the Judgment Currency, such Lender or the Agent, in accordance with normal
banking procedures, purchases the Original Currency with the Judgment Currency.
If the amount of Original Currency so purchased is less than the sum originally
due to such Lender or the Agent, the Borrower agrees as a separate obligation
and notwithstanding any such judgment, to indemnify each Lender and the Agent,
as the case may be, against such loss, and if the amount of Original Currency so
purchased exceeds the sum originally due to such Lender and the Agent, as the
case may be, each Lender and the Agent agree to remit any excess to the
applicable Obligor. If, for the purpose of obtaining judgment in any court, it
is necessary to convert a sum due under any Loan Document in another currency
into Dollars, Canadian Dollars or Sterling, as the case may be, the parties
hereto agree, to the fullest extent that they may effectively do so, that the
rate of exchange used shall be that at which, in accordance with normal banking
procedures, the applicable Lender could purchase such other currency with
Dollars, Canadian Dollars or Sterling, as the case may be, in New York, at the
close of business on the Business Day immediately preceding the day on which
final judgment is given, together with any premiums and costs of exchange
payable in connection with such purchase.

         This FIRST AMENDMENT, dated as of August 7, 2003 (this "Amendment"), to
the Amended and Restated Credit Agreement, dated as of July 16, 2003 (as the
same may be amended, supplemented or otherwise modified from time to time, the

                              W I T N E S S E T H:

         WHEREAS, the Borrower, the Lenders and the Agent have heretofore
entered into the Credit Agreement; and

         WHEREAS, the Borrower, the Lenders and the Agent now desire to amend
the Credit Agreement in certain respects, as hereinafter provided;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein contained and for other good and valuable consideration, the
receipt of which is hereby acknowledged, the Borrower, the Lenders and the Agent
hereby agree as follows:

         SECTION 1. Defined Terms. Unless otherwise defined herein, capitalized
terms used herein shall have the meanings set forth in the Credit Agreement.

         SECTION 2. Amendment to Section 1.1 (Defined Terms). Section 1.1 of the
Credit Agreement is hereby amended by deleting therefrom the definition of

Loan, 2.50% per annum, and (iv) for any Term B Loan that is a LIBO Rate Loan,
3.50% per annum.

         SECTION 3. Amendment to Section 3.3.3 (Letter of Credit Fee). Section
3.3.3 of the Credit Agreement is hereby amended by deleting the text of such
Section 3.3.3 in its entirety and substituting in its place the following new
text:

         "The Borrower agrees to pay to the Agent, for the account of the
Revolving Lenders, for each Letter of Credit for the period from and including
the date of the issuance of such Letter of Credit to (and including) the date
upon which (or on the next succeeding Business Day upon which) such Letter of
Credit expires or is returned to the Issuer that issued such Letter of Credit, a
fee, in Dollars, on the average daily stated amount of such Letter of Credit (or
the Equivalent Amount thereof with respect to Foreign Currency Letters of
Credit) calculated at a per annum rate equal to the Applicable Margin for
Revolving Loans that are LIBO Rate Loans in effect from time to time. Such fee
shall be payable by the Borrower in arrears on each Quarterly Payment Date, and
on the date of termination or expiry of the last Letter of Credit outstanding

<PAGE>

hereunder (for any period then ending for which such fee shall not theretofore
have been paid), commencing on the first such date after the issuance of such
Letter of Credit."

giving effect to this Amendment.

         SECTION 5. Representations and Warranties. The Borrower hereby
represents and warrants that the representations and warranties contained in the
Credit Agreement (except those which expressly speak as of a certain date) will
be, after giving effect to this Amendment, true and correct in all material
respects, as if made on and as of the date hereof.

         SECTION 6. Continuing Effect of Credit Agreement. This Amendment shall
not constitute an amendment or waiver of any other provision of the Credit
Agreement or the Loan Documents not expressly referred to herein and shall not
be construed as a waiver or consent to any further or future action on the part
of the Borrower that would require a waiver or consent of the Agent and/or the
Lenders. Except as expressly amended hereby, the provisions of the Credit
Agreement and the Loan Documents shall remain in full force and effect. All
references to the Credit Agreement in any other document, instrument, agreement
or writing shall hereafter be deemed to refer to the Credit Agreement as amended
hereby.

         SECTION 7. Counterparts. This Amendment may be executed in counterparts
and all of the said counterparts taken together shall be deemed to constitute
one and the same instrument. Delivery of an executed signature page of this
Amendment by facsimile transmission shall be effective as delivery of a manually
executed counterpart hereof.

INTERNAL LAWS OF THE STATE OF NEW YORK.
