                              ---------------------

           SECTION II.1. The Revolving Credit Loans.

           (a) Subject to the terms and conditions set forth in this Agreement,
on and after the Closing Date until (but excluding) the Availability Expiration
Date, each Lender severally agrees to make loans to the Borrower (the "Revolving
Credit Loans") in an aggregate principal amount (including such Lender's
Proportionate Share of the aggregate amount of all outstanding Letters of
Credit) not to exceed its Proportionate Share of the lesser of (i) the Maximum
Amount of the Facility and (ii) 87% of the Projected Adjusted Consolidated
Unrestricted Cash Flow at such time projected to be received by the Borrower for
the period commencing on the Availability Expiration Date until the Term Loan
Maturity Date and discounted at a discount rate equal from time to time to the
current applicable interest rate under Section 4.1.

           (b) Subject to the right of the Borrower to convert all Revolving
Credit Loans to Term Loans under Section 2.10, each Revolving Credit Loan shall
be payable in full, with all interest accrued thereon, on the Availability
Expiration Date. The Borrower may borrow, repay and reborrow Revolving Credit
Loans, in whole or in part, in accordance with the terms hereof.

                                      -23-
<PAGE>

           (c) The proceeds of the Revolving Credit Loans shall be used by the
Borrower only for working capital purposes including, without limitation, for
(i) the type of expenditures reflected in the Business Plan, including, without
limitation, operating and maintenance expenses, general and administrative
expenses, development expenses (including the acquisition and development of,
and investment in, Facilities to the extent permitted under this Agreement), and
Capital Expenditures and (ii) expenses caused by waterflow shortfalls or other
unexpected events, and, in all cases, to the extent not otherwise prohibited by
this Agreement.

           (d) Upon not less than three Business Days' prior notice from the
Borrower to the Agent, the Borrower may reduce permanently, in whole or in part,
the commitment of the Lenders to make Revolving Credit Loans and to purchase
participations in Letters of Credit caused to be issued by the Agent, and of the
Agent to cause to be issued Letters of Credit, provided that (i) any partial
reduction shall be in an integral multiple of $1,000,000, (ii) any such notice
shall be irrevocable once given and (iii) any reduction of such commitment in
full shall be subject to the payment of the fee specified in Section 4.7, if
such reduction occurs prior to the first anniversary of the Closing Date.

           SECTION II.2. Procedures for Borrowing of Revolving Credit Loans;
Disputes.

           (a) So long as the conditions for borrowing contained in Section 5.1
or 5.2 (whichever section is applicable) are satisfied, upon notice from the
Borrower to the Agent, substantially in the form of Exhibit O (a "Notice of
Borrowing") received by the Agent as set forth in Section 2.5, Revolving Credit
Loans shall be made to the Borrower to the extent of each Lender's Proportionate
Share of the requested Borrowing.

<PAGE>

           (b) Within two Business Days after the making of each Revolving
Credit Loan (other than the initial Revolving Credit Loans), the Agent will
provide each Lender with copies of the documentation furnished by the Borrower
supporting such Revolving Credit Loan. In the event that any Lender reasonably
determines in good faith that such documentation does not comply with the
requirements of Section 5.2 of this Agreement in any material respect, such
Lender shall promptly so notify the Agent and the Borrower. Failure to give any
such notice within five days after its receipt of such documentation shall
preclude a Lender from giving such notice with respect to the applicable
Revolving Credit Loan (but not any future Revolving Credit Loan). Upon receipt
of any such notice, the Agent and the Lender giving the same shall promptly
endeavor to resolve the discrepancies raised by such Lender. In the event the
discrepancies are not resolved to the Lender's reasonable satisfaction, and the
Lender so notifies the Agent and the Borrower in writing, such Lender shall have
no obligation to make available to the Agent its Proportionate Share of any
later Revolving Credit Loan until the discrepancy is resolved and, so long as
the discrepancy is unresolved, the Borrower shall have the right to replace such
Lender with a Replacement Lender in accordance with the procedures specified in
Section 2.9. Upon resolution of any such discrepancy or if the Required Lenders
determine that the discrepancy is immaterial or otherwise agree to waive such
discrepancy, the applicable Lender shall promptly remit all withheld amounts to
the Agent.

           SECTION II.3. Disbursement of Revolving Credit Loans. Except as
provided in Section 2.11(f), the proceeds of the Revolving Credit Loans shall be
transmitted by the Agent as requested by the Borrower in each applicable Notice
of Borrowing.

           SECTION II.4. Term. Each Lender's obligation under Sections 2.1(a)
and 2.11(a) and (f) to make Revolving Credit Loans and to purchase
participations in letters of credit caused to be issued by the Agent, and the
Agent's obligation to use its best efforts to cause to be issued Letters of
Credit, shall commence on the Closing Date and extend through the Initial
Availability Expiration Date, unless sooner terminated by the terms hereof,
provided that the Availability Expiration Date shall be extended for successive
one-year periods beyond the then-effective expiration date unless the Borrower
notifies the Agent and the Lenders, or the Agent notifies the Borrower, in
writing at least ninety and no more than one hundred fifty days prior to the
then effective Availability Expiration Date that it does not wish to extend the
Availability Expiration Date. Without limitation of the preceding sentence, each
Lender's obligations under Sections 2.1(a) and 2.11(a) and (f) to make Revolving
Credit Loans and to purchase participations in Letters of Credit shall terminate
if such terminating Lender notifies the Agent, the Borrower and the other
Lenders in writing (a "Termination Notice") at least one hundred fifty and no
more than two hundred ten days prior to the then effective Availability
Expiration Date that it wishes to terminate such obligations, provided that each
non-terminating Lender shall have, upon receipt of a timely Termination Notice
from a terminating Lender, an additional five Business Days to deliver a
Termination Notice to the Agent and the other Lenders, which Termination Notice
shall be fully effective to terminate such Lender's obligations under Section
2.1(a) and 2.11(a) and (f) to make Revolving Credit Loans and to purchase
participations in Letters of Credit, and provided, further, that no Termination
Notice shall be effective if delivered less than one hundred forty-five days
prior to the then effective Availability Expiration Date.

           SECTION II.5. Notices of Borrowing.

           (a) Each Revolving Credit Loan shall be requested by the Borrower
pursuant to a Notice of Borrowing given to the Agent no later than 11:00 a.m.
(New York time) on the third Business Day prior to the proposed date of such
Revolving Credit Loan (which date shall be a Business Day). Each request for a
Revolving Credit Loan shall be made by telephone, confirmed immediately by
telecopier in a Notice of Borrowing signed by a Secretary or Assistant Secretary
of the Borrower, and shall specify therein (i) the proposed date of such
Revolving Credit Loan, (ii) the proposed aggregate principal amount of such
Revolving Credit Loan, (iii) the proposed use of the proceeds of such Revolving
Credit Loan and (iv) that the Projected Minimum Coverage Ratio as of the date
thereof is not less than the ratio projected in the Business Plan as of such
date or, if such ratio is less than such projected ratio, a calculation of the
Projected Minimum Coverage Ratio as of such date taking into account the
aggregate principal amount of the proposed Revolving Credit Loan, which ratio
shall not be less than 1.15:1.00).

<PAGE>

           (b) Promptly after receipt of a Notice of Borrowing, the Agent shall
provide each Lender with a copy thereof.

           SECTION II.6. Disbursement of Funds; Evidence of Debt to Lenders;
Account Statements; Adjustments.

           (a) Subject to the satisfaction of the conditions for each Revolving
Credit Loan under Section 5.1 (for the initial Revolving Credit Loan) and
Section 5.2 (for each other Revolving Credit Loan), each Lender shall, before
11:00 a.m. (New York time) on the requested date of such Revolving Credit Loan,
make available to the Agent at the Agent's address, in United States dollars and
immediately available funds, such Lender's Proportionate Share of such Revolving
Credit Loan. After the Agent's receipt of such funds, the Agent will make such
received funds available to the Borrower by 2:00 p.m. (New York time) on the
proposed date of the applicable Revolving Credit Loan by wire transfer to the
Borrower. Unless the Agent receives contrary written notice prior to the date of
any such borrowing of Revolving Credit Loans, the Agent is entitled to assume
that each Lender will make available its Proportionate Share of the borrowing
and in reliance upon that assumption, but without any obligation to do so, may
advance such Proportionate Share on behalf of such Lender. The Agent shall
promptly notify the Borrower of the Agent's receipt of each Lender's
Proportionate Share, provided that the Agent's failure to provide such notice to
the Borrower shall not limit or otherwise affect any of the rights of the Agent
hereunder. If and to the extent that such Lender shall not have made such amount
available to the Agent, but the Agent has made such amount available to the
Borrower, such Lender and the Borrower severally agree to pay and repay the
Agent forthwith on demand such corresponding amount and to pay interest thereon,
for each day from the date such amount is transferred by the Agent to the
Borrower until the date such amount is paid or repaid to the Agent, at (i) in
the case of the Borrower, the interest rate applicable at such time to such
Revolving Credit Loan and (ii) in the case of each Lender, for the period from
the date such amount was wire transferred to the Borrower to (and including)
three days after demand therefor by the Agent to such Lender, at the Federal
Funds Rate and, following such third day, at the interest rate applicable at
such time to such Revolving Credit Loan, provided, that such Lender shall not be
required to pay to the Agent the principal of any amount not made available to
the Agent by such Lender and any interest payable by such Lender thereon to the
extent such principal and interest have been repaid by the Borrower. If a Lender
shall pay to the Agent any or all of such amount, such amount so paid shall
constitute a Revolving Credit Loan by such Lender to the Borrower for purposes
of this Agreement.

                                      -28-
<PAGE>

           (b) The Agent shall maintain in its records one or more accounts
evidencing the Obligations and the amounts of Loans made by each Lender and of
principal and interest payable and paid to each Lender from time to time under
this Agreement. In any legal action or proceeding in respect of this Agreement,
the Agent's records shall be conclusive evidence of the existence and amounts of
the Obligations, absent manifest error. The Agent shall provide the Borrower and
the Lenders with statements of the accounts maintained by it hereunder promptly
following the making of each Revolving Credit Loan, the receipt of each payment
to the Agent under this Agreement and any other adjustments made by the Agent to
such accounts from time to time.

           (c) If the Agent inadvertently distributes to a Lender under Section
2.7 an amount in excess of the amount then due such Lender by the Agent under
Section 2.7, then such Lender shall repay to the Agent forthwith, on demand,
such excess amount distributed to such Lender together with interest thereon,
for each day from the date such amount is distributed to such Lender until the
date such Lender repays such amount to the Agent, at the Federal Funds Rate.

           SECTION II.7. Payments.

           The Borrower shall make each payment hereunder not later than 11:00
a.m. (New York time) on the day when due, in Dollars, to the Agent at the
Agent's address in immediately available funds. The Agent will promptly after
receiving payments from the Borrower hereunder cause like funds to be
distributed to the Lenders, ratably, at their addresses and in accordance with
the terms of this Agreement.

<PAGE>

           SECTION II.8. Sharing of Payments. If any Lender shall obtain any
payment on account of any of the Obligations (whether voluntary, involuntary,
through the exercise of any right of set-off or otherwise), such Lender shall
forthwith purchase from the other Lenders such participations in the Obligations
as shall be necessary to cause such purchasing Lender to share the excess
payment ratably with each of them; provided, however, that if all or any portion
of such excess payment is thereafter recovered from such purchasing Lender, such
purchase from each Lender shall be rescinded and each such Lender shall repay to
the purchasing Lender the purchase price to the extent of such recovery together
with an amount equal to such Lender's ratable share (according to the proportion
of (i) the amount of such Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect to the total amount so recovered;
and provided, further that this Section shall not apply with respect to any fees
payable solely to the Agent or any other fees that are intended to be for the
benefit of less than all of the Lenders. 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 of its rights of payment
(including, without limitation, the right of setoff) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation. Notwithstanding anything contained
herein to the contrary, the sharing provisions of this Section shall not apply
to any payments received by any Lender from or on behalf of the Borrower or the
Agent that is not made pursuant to the express terms and provisions of this
Agreement.

<PAGE>

           SECTION II.9. Defaulting Lenders.

           (a) A Lender who fails to pay the Agent its Proportionate Share of
any Revolving Credit Loans duly made available by the Agent on such Lender's
behalf, or who fails to pay any other amount owing by it to the Agent, is a
defaulting lender (a "Defaulting Lender"). The Agent may recover all such
amounts owing by a Defaulting Lender on demand. If the Defaulting Lender does
not pay such amounts on the Agent's demand, the Agent shall promptly notify the
Borrower and the Borrower shall pay such amounts with all accrued interest
thereon until the date of payment within five Business Days or, in the case of a
Revolving Credit Loan deemed to be made on account of a drawing under a Letter
of Credit, within thirty days. In addition, the Defaulting Lender and the
Borrower shall pay (without duplication) the Agent interest on such amount for
each day from the date it was made available by the Agent to the Borrower to the
date it is recovered by the Agent at a rate per annum equal to (x) the overnight
Federal Funds Rate, if paid by the Defaulting Lender, or (y) the then applicable
rate of interest calculated under Section 4.1, if paid by the Borrower; plus, in
each case, the expenses and losses, if any, incurred as a result of the
Defaulting Lender's failure to perform its obligations. The Borrower shall
reimburse a Defaulting Lender for all interest paid by such Defaulting Lender to
the Agent under the preceding sentence which the Borrower has not paid to the
Agent under the preceding sentence so long as the Borrower has paid all
Obligations to the Agent and the other Lenders then due and payable and no Event
of Default has occurred and is continuing. The Borrower may, by notice (a
"Replacement Notice") in writing to the Agent and such Defaulting Lender, (A)
request the Defaulting Lender to cooperate with the Borrower in obtaining a
Replacement Lender; (B) request the non-Defaulting Lenders to acquire and assume
all or a portion of the Defaulting Lender's Loans and Revolving Credit
Commitments, but none of such Lenders shall be obligated to do so; or (C)
propose a Replacement Lender. If a Replacement Lender shall be accepted by the
Agent or one or more of the non-Defaulting Lenders shall agree to acquire and
assume all or part of the Defaulting Lender's Loans and Revolving Credit
Commitment, then such Defaulting Lender shall assign, in accordance with Section
11.8, all or part, as the case may be, of its Revolving Credit Commitment,
Loans, Notes and other rights and obligations under this Agreement and all other
Loan Documents to such Replacement Lender or non-Defaulting Lenders, as the case
may be, in exchange for payment of the principal amount or the portion thereof
so assigned and all interest and fees accrued on the portion thereof so
assigned, plus all or part, as the case may be, of the other Obligations then
due and payable to the Defaulting Lender; provided, however, that (i) such
assignment shall be on the terms and conditions set forth in Section 11.8, and
(ii) prior to any such assignment, the Borrower shall have (x) paid to such
Defaulting Lender all amounts properly demanded and theretofore unpaid by the
Borrower under Section 4.9

                                      -31-
<PAGE>

(less costs and expenses incurred by the Borrower directly as a result of the
actions of the Defaulting Lender) and (y) paid to the Agent all amounts properly
demanded and theretofore unpaid by the Borrower under Sections 4.1, 4.4 and 4.5
(but not Section 4.7). If the Replacement Lender and non-Defaulting Lenders
shall only be willing to acquire less than all of the Defaulting Lender's
outstanding Loans and Revolving Credit Commitment, the Revolving Credit
Commitment of the Defaulting Lender shall not terminate, but shall be reduced
proportionately, and the Defaulting Lender shall continue to be a "Lender"
hereunder with a reduced Revolving Credit Commitment and Proportionate Share.
Upon the effective date of such assignment, the Borrower shall issue replacement
Notes to such Replacement Lender, non-Defaulting Lenders and the Defaulting
Lender, as the case may be, in exchange for the Notes of the Defaulting Lender
theretofore outstanding, and such Replacement Lender shall, if not already a
Lender, become a "Lender" for all purposes under this Agreement and the other
Loan Documents.

           (b) The failure of any Lender to fund its Proportionate Share of any
Revolving Credit Loan shall not relieve any other Lender of its obligation to
fund its Proportionate Share of such Revolving Credit Loan. Conversely, no
Lender shall be responsible for the failure of another Lender to fund such other
Lender's Proportionate Share of a Revolving Credit Loan.

                                      -32-
<PAGE>

           (c) The Agent shall not be obligated to transfer to a Defaulting
Lender any payments made by the Borrower to the Agent for the Defaulting
Lender's benefit; nor shall a Defaulting Lender be entitled to the sharing of
any payments hereunder. Amounts payable to a Defaulting Lender shall instead be
paid to or retained by the Agent. The Agent may hold and, in its discretion,
re-lend to the Borrower the amount of all such payments received or retained by
it for the account of such Defaulting Lender, provided that, the Defaulting
Lender shall be entitled to interest at the Federal Funds Rate on all such
amounts held by the Agent for the account of such Defaulting Lender from the
initial date on which such amount is so held by the Agent until the date on
which such amount is released to such Defaulting Lender. For purposes of voting
or consenting to matters with respect to the Loan Documents and determining
Proportionate Shares, such Defaulting Lender shall be deemed not to be a
"Lender" and such Lender's Commitment and Loans shall be deemed to be zero,
provided that, with respect to any action hereunder requiring the consent of all
the Lenders, the Agent agrees to provide a Defaulting Lender with two Business
Days' prior notice before taking such action, and provided, further, that the
failure of the Agent to provide a Defaulting Lender with such notice shall not
limit or otherwise affect any such action taken by the Agent. This Section shall
remain effective with respect to such Lender until (x) the Defaulting Lender has
paid all amounts required to be paid to the Agent hereunder or (y) the Required
Lenders, the Agent and the Borrower shall have waived such Lender's default in
writing. The operation of this Section shall not be construed to increase or
otherwise affect the Commitment of any Lender, or relieve or excuse the
performance by the Borrower of its duties and obligations hereunder.

           SECTION II.10. Conversion to Term Loan.

           (a) Subject to and upon the satisfaction of the terms and conditions
specified in subsection (b) below, the Borrower may, on the Availability
Expiration Date, convert the amount of all, but not less than all, outstanding
Revolving Credit Loans of each Lender to a Term Loan of such Lender (as such
amount may be increased from time to time under Section 2.11(c), each, a "Term
Loan").

           (b) The right of the Borrower to convert all outstanding Revolving
Credit Loans to Term Loans is subject to the satisfaction of each of the
following conditions:

                      (i) The Agent shall have received written notice from the
           Borrower before the Availability Expiration Date requesting such
           conversion and specifying the aggregate principal amount of the Term
           Loans (which shall be equal to the amount of all outstanding
           Revolving Credit Loans on the Availability Expiration Date). The
           Agent shall promptly notify each of the Lenders of such request.

                                      -33-
<PAGE>

                      (ii) The Lenders shall have each received a Term Note,
           payable to it and duly executed by the Borrower with appropriate
           insertions as to the date and principal amount.

                      (iii) The aggregate principal amount of all outstanding
           Revolving Credit Loans, before giving effect to the conversion, shall
           be greater than $2,000,000.

                      (iv) The Agent shall have received a certificate of the
           Borrower, in form and substance satisfactory to the Agent, duly
           executed by the chief accounting officer of the Borrower, as of the
           date of such conversion, truthfully stating that (A) the
           representations and warranties contained in Article VI are true and
           correct, except to the extent that such representations and
           warranties expressly relate to an earlier date, in which case such
           representations and warranties shall be true and correct as of such
           earlier date and (B) no Default has occurred and is continuing or
           would result after giving effect to the conversion.

                      (v) No material provision of this Agreement or any other
           Loan Document shall for any reason have ceased to be valid and
           binding on the Borrower or any other Pledgor or party thereto or
           shall have been declared to be null and void by any court,
           Governmental Authority or administrative body.

                      (vi) The Agent shall have received a board resolution
           authorizing such conversion, certified by the Secretary or an
           Assistant Secretary of the Borrower, in form and substance
           satisfactory to the Agent.

           SECTION II.11. Letters of Credit.

           (a) Subject to the terms and conditions set forth in this Agreement,
on and after the Closing Date until (but excluding) the Availability Expiration
Date, the Agent, upon the request of the Borrower, shall use its best efforts to
cause a bank or financial institution acceptable to the Agent and the Borrower
to issue Letters of Credit for the account or benefit of the Borrower or any of
its Affiliates. Each Letter of Credit shall be requested in accordance with the
Borrower's or such Affiliate's ordinary business requirements in the operation
and development of Facilities to support equity commitments or obligations of
such Person under power purchase or other material project agreements, each with
(i) a tenor and containing terms acceptable to the Borrower, the Agent and the
issuer of such Letter of Credit and (ii) in the case of a Letter of Credit
issued for the account or benefit of an Affiliate that is not wholly owned by
the Borrower, a purpose and benefit to the Borrower reasonably acceptable to the
Lender. The Agent shall not be required to use its best efforts to cause, and
the Borrower shall not request, the issuance of any Letter of Credit if (i)
after giving effect thereto, the maximum aggregate amount of all Letters of
Credit and Revolving Credit Loans outstanding at such time would exceed the
lesser of (A) the Maximum Amount of the Facility and (B) 87% of the Projected
Adjusted Consolidated Unrestricted Cash Flow at such time projected to be
received by the Borrower for the period commencing on the Availability
Expiration Date until the Term Loan Maturity Date and discounted at a discount
rate equal from time to time to the current applicable interest rate under
Section 4.1; or (ii) a default of any Lender's obligations to fund under this
Section 2.11 exists, or any Lender is a Defaulting Lender, unless the Agent has
entered into satisfactory arrangements with the Borrower to eliminate the
Agent's risk with respect to such Lender, including cash collateralization of
such Lender's Proportionate Share of the Obligations in respect of Letters of
Credit.

                                      -35-
<PAGE>

           (b) Unless otherwise previously agreed in writing by the Borrower and
the Agent, the initial term of any Letter of Credit shall not exceed one
calendar year from the date of issuance, subject to automatic renewal unless
notice to the contrary is given by the Agent or the issuing bank in writing by
the applicable date specified in such Letter of Credit. Each Letter of Credit
shall state that, except as otherwise provided therein, such Letter of Credit is
governed by the Uniform Customs and Practice for Documentary Credits (as most
recently published by the International Chamber of Commerce). Notwithstanding
the purpose of any Letter of Credit or any reference therein or herein to an
Affiliate of the Borrower, each Letter of Credit shall be deemed issued for the
account of the Borrower and the obligations arising in connection therewith
shall be part of the Obligations.

           (c) Subject to the agreement of the beneficiary thereof, any Letter
of Credit outstanding after the earlier of (i) the occurrence and continuance of
an Event of Default or (ii) the fifth anniversary of the Availability Expiration
Date, may be reduced, in whole or in part, in an amount to be advanced by the
Agent, from funds made available by the Lenders, to such beneficiary for the
account of the Borrower (or any Subsidiary of the Borrower for whose account
such Letter of Credit was issued). The amount of such advance by each Lender
shall be added to the then outstanding balance of such Lender's respective Term
Loan and shall be deemed a part thereof. The proceeds of such advance shall be
held by a depository for the account of such beneficiary and, to the extent such
proceeds are no longer required as collateral by such beneficiary, shall
thereupon be returned to each of the Lenders for application to such Lender's
Term Loan, in inverse order of maturity or, if such Term Loan has been paid in
full, for deposit to the L/C Cash Collateral Account.

           (d) Immediately upon issuance or amendment of any Letter of Credit in
accordance with the procedures set forth in this Section 2.11, each Lender shall
be deemed to have irrevocably and unconditionally purchased and received from
the Agent, without recourse or warranty, an undivided interest and
participation, to the extent of such Lender's Proportionate Share, of the
liability and obligations under and with respect to such Letter of Credit and
the Letter of Credit Agreement (including, without limitation, all obligations
of the Borrower with respect thereto, other than amounts owing to the Agent
consisting of fees payable in connection with the issuance of Letters of Credit)
and any security therefor or guaranty pertaining thereto.

                                      -36-
<PAGE>

           (e) Whenever the Borrower desires the issuance of a Letter of Credit,
the Borrower shall deliver to the Agent a written notice no later than 1:00 P.M.
New York City time at least five Business Days (or such shorter period as may be
agreed to by the Agent) in advance of the proposed date of issuance of a letter
of credit request in substantially the form attached as Exhibit K (a "Letter of
Credit Request"). The transmittal by the Borrower of each Letter of Credit
Request shall be deemed to be a representation and warranty by the Borrower that
the Letter of Credit may be issued in accordance with and will not violate any
of the requirements of this Section 2.11. Prior to the date of issuance of each
Letter of Credit, the Borrower shall provide to the Agent a precise description
of the documents and the text of any certificate to be presented by the
beneficiary of such Letter of Credit which, if presented by such beneficiary on
or prior to the expiration date of such Letter of Credit, would require the
issuing bank to make payment under such Letter of Credit. The Agent, in its
reasonable judgment, may require changes in any such documents and certificates.
A Letter of Credit Request may be given in writing or electronically with prompt
written confirmation. Any electronic Letter of Credit Request shall be deemed to
have been prepared by, or under the supervision of, the chief accounting officer
of the Borrower.

<PAGE>

           (f) In the event of any request for drawing under any Letter of
Credit by the beneficiary thereof prior to the Availability Expiration Date, (i)
the Borrower shall be deemed to have timely given a Notice of Borrowing to the
Agent to make Revolving Credit Loans on the date on which such drawing is
honored in an amount equal to the amount of such drawing and (ii) without regard
to satisfaction of the applicable conditions specified in Section 5.2 and the
other terms and conditions of borrowings contained herein, the Lenders shall, on
the date of such drawing, make Revolving Credit Loans in the amount of such
drawing, the proceeds of which shall be applied directly by the Agent to
reimburse the issuing bank for the amount of such drawing or payment. If for any
reason, proceeds of Revolving Credit Loans are not received by the Agent on such
date in an amount equal to the amount of such drawing, the Borrower and the
non-funding Lender shall be obligated to and shall reimburse the Agent as
provided in Section 2.6(a), on the Business Day immediately following the date
of such drawing in the case of the non-funding Lender and within thirty days in
the case of the Borrower, in an amount in same day funds equal to the excess of
the amount of such drawing over the amount of such Loans, if any, which are so
received, plus accrued interest on such amount at the rate set forth in Section
4.1. In the event of a request for drawing under any Letter of Credit by the
beneficiary thereof after the Availability Expiration Date but prior to the Term
Loan Maturity Date, the amount of such drawing shall be payable by the Borrower
on demand (to be paid from cash on deposit in the L/C Cash Collateral Account to
the extent available) and, until paid by the Borrower, shall bear interest
applicable to Term Loans under Section 4.1(ii).

                                      -38-

           (g) As among the Borrower, the Agent and each Lender, the Borrower
assumes all risks of the acts and omissions of the Agent and the issuing bank or
misuse of the Letters of Credit by the respective beneficiaries of such Letters
of Credit. In furtherance and not in limitation of the foregoing, neither the
Agent nor any of the Lenders shall be responsible (i) for the form, validity,
sufficiency, accuracy, genuineness or legal effects of any document submitted by
any party in connection with the application for and issuance of or any drawing
honored under such Letters of Credit even if it should in fact prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent or forged,
(ii) for the validity or sufficiency of any instrument transferring or assigning
or purporting to transfer or assign any such 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, (iii) for failure of the beneficiary
of any such Letter of Credit to comply fully with conditions required in order
to draw upon such Letter of Credit, (iv) for errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex, telecopy or otherwise, whether or not they be in cipher, (v) for errors
in interpretation of technical terms, (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any such Letter of Credit, or of the proceeds thereof, (vii) for the
misapplication by the beneficiary of any such Letter of Credit, of the proceeds
of any drawing honored under such Letter of Credit, and (viii) for any
consequences arising from causes beyond the control of the issuing bank, the
Agent or the Lenders. None of the above shall affect, impair, or prevent the
vesting of any of the Agent's rights or powers hereunder. Any action taken or
omitted to be taken by the Agent under or in connection with any Letter of
Credit, if taken or omitted in the absence of gross negligence or willful
misconduct, shall not create any liability of the Agent to the Borrower or any
Lender.

                                      -39-
<PAGE>

           (h) The obligations of the Borrower to reimburse the Agent for
drawings honored under the Letters of Credit and the obligations of the Lenders
under this Section 2.11 shall be unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances
including, without limitation, the following circumstances: (i) any lack of
validity or enforceability of this Agreement, any Letter of Credit, any Letter
of Credit Agreement or any other agreement or instrument relating thereto; (ii)
the existence of any claim, setoff, defense or other right which the Borrower or
any Affiliate of the Borrower may have at any time against a beneficiary or any
transferee of any Letter of Credit (or any Persons or entities for whom any such
beneficiary or transferee may be acting), the Agent, any Lender or any other
Person, whether in connection with this Agreement, the other Loan Documents, the
transactions contemplated herein or therein or any unrelated transaction; (iii)
any draft, demand, certificate or other documents presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect; (iv) the
surrender or impairment of any security for the performance or observance of any
of the terms of any of the Loan Documents; (v) payment by the issuing bank under
any Letter of Credit against presentation of a demand, draft or certificate or
other document which does not comply with the terms of such Letter of Credit;
(vi) failure of any drawing under a Letter of Credit or any non-application or
misapplication by the beneficiary of the proceeds of any drawing; or (vii) the
fact that a Default or Event of Default shall have occurred and be continuing.
Any action taken or omitted to be taken by an issuing bank in connection with
any payment under a Letter of Credit, if taken or omitted in the absence of
gross negligence or willful misconduct, shall not create any liability of the
Agent or the issuing bank to the Borrower or any Lender or of any Lender to the
Borrower.

           SECTION II.12. Amortization of Term Loan; Cash Collateralization of
Letters of Credit.

           (a) Commencing on the Availability Expiration Date, the Borrower
shall pay to the Agent for the ratable benefit of the Lenders, in consecutive
quarterly installments commencing on the last Business Day of the calendar
quarter immediately following the Availability Expiration Date, and on the last
Business Day of each calendar quarter thereafter, 25% of the Annual Term Loan
Principal Amortization for each consecutive four calendar quarter period
commencing with such initial calendar quarter, which payments shall continue
until the repayment in full of the principal outstanding amount of the Term
Loans and any accrued and unpaid interest thereon, and the cash
collateralization in full of the undrawn amount of all outstanding Letters of
Credit; provided, however, that all such amounts shall be repaid or
cash-collateralized in full on or before the Term Loan Maturity Date. The
amounts required to be paid hereunder may be reduced by all prepayments and
deposits received by the Agent under Section 2.13 and the amount of all letters
of credit issued in replacement of the Letters of Credit, in each case after the
Availability Expiration Date.

           (b) All payments received by the Lenders under subsection (a) hereof
or under Section 4.1(ii) shall be (i) applied first to any accrued and unpaid
interest on the Term Loans and then to the outstanding principal amount of the
Term Loans and (ii) upon the repayment in full of the Term Loans, deposited into
the L/C Cash Collateral Account to be held and applied as provided in Section
9.2(d).

           (c) If requested by the Borrower, the Agent will, so long as no
Default has occurred and is continuing, from time to time, (i) invest amounts on
deposit in the L/C Cash Collateral Account in such Cash Equivalents in the name
of the Agent as the Borrower may select and (ii) invest interest paid on the
Cash Equivalents referred to in clause (i) hereof, and reinvest other proceeds
of any such Cash Equivalents that may mature or be sold, in each case in such
Cash Equivalents in the name of the Agent as the Borrower may select. Interest
and proceeds that are not invested or reinvested as provided above shall be
deposited and held in the L/C Cash Collateral Account.

                                      -41-
<PAGE>

           (d) No amount (including interest and other income earned on any
Investments) shall be paid or released to or for the account of, or withdrawn by
or for the account of, the Borrower or any other Person from the L/C Cash
Collateral Account until the payment in full of all the Obligations, provided
that interest and other income earned on Investments may, upon the written
request of the Borrower (but in no event more frequently than once each calendar
quarter), be applied toward payment of the Obligations specified by the Borrower
in such written request, and provided further that, so long as all the
Obligations have been paid in full and the Borrower has deposited in the L/C
Cash Collateral Account an amount not less than the aggregate then undrawn
amount of the outstanding Letters of Credit, all investment income will be paid
to the Borrower when received.

           (e) The L/C Cash Collateral Account shall be subject to such
applicable laws, and such applicable regulations of the Federal Reserve Board
and of any other appropriate Governmental Authority, as may now or hereafter be
in effect.

           SECTION II.13. Maximum Amount of the Facility; Mandatory Prepayments;
Optional Prepayments.

           (a) In no event shall the sum of the aggregate outstanding principal
balances of the Revolving Credit Loans (plus the Interest Reserve) or the Term
Loans, as the case may be, and the aggregate undrawn amount of all outstanding
Letters of Credit exceed the Maximum Amount of the Facility.

           (b) In addition to any prepayment required as a result of an Event of
Default hereunder, the Borrower shall make mandatory prepayments as follows:

                      (i) not later than thirty days after the receipt by the
           Borrower or any of its Designated Subsidiaries of any proceeds of a
           sale permitted under Section 7.2(g)(iii) or (vi) that occurs after
           the Availability Expiration Date, the Borrower shall prepay or cause
           such Designated Subsidiary to prepay to the Agent for the ratable
           benefit of the Lenders an amount equal to all net proceeds of all of
           such sales (other than proceeds that may not be so applied under the
           terms of instruments of Permitted Indebtedness or any Requirement of
           Law applicable to the Borrower or such Designated Subsidiary) in
           excess of $100,000 in the aggregate in any fiscal year (except, if
           any such sale is of Equipment, to the extent such proceeds are used
           within thirty days of receipt thereof to purchase replacement
           equipment of equal or greater value in

                                      -42-
<PAGE>

           which equipment the Agent has been granted a perfected first priority
           security interest for the benefit of the Lenders, satisfactory proof
           of which shall have been given to the Agent within such thirty-day
           period), which payments shall be ratably applied to the Term Loans in
           inverse order of maturity;

                      (ii) immediately upon discovery by or notice to the
           Borrower that the lending limit specified in Section 2.13(a) has been
           exceeded, the Borrower shall prepay to the Agent an amount sufficient
           to reduce the outstanding balances to the applicable maximum allowed
           amount, without the necessity of a demand by the Agent; and

                      (iii) immediately upon the release of any proceeds held by
           a beneficiary of such proceeds as provided in Section 2.11(c), the
           Borrower shall prepay to the Agent for the ratable benefit of the
           Lenders an amount equal to all such proceeds, which amount shall be
           ratably applied to the Term Loans in inverse order of maturity.

           (c) The Borrower shall have the right at any time to make prepayments
of the Loans, or deposit cash in the L/C Cash Collateral Account before any date
on which such deposit is required, in each case without premium or penalty,
except as provided in Section 4.7, upon irrevocable notice given to the Agent
prior to 11:00 A.M., New York City time, at least two Business Days prior to the
date of such prepayment or deposit, specifying the date and amount thereof. If
any such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein. Any prepayment of the Loans under this
Section shall be applied as reasonably specified by the Borrower in such notice
or, if an Event of Default has occurred and is continuing, as the Required
Lenders shall elect in their sole discretion.

           (d) The entire outstanding principal amount of the Revolving Credit
Loans, subject to Section 2.10, together with all accrued and unpaid interest
thereon and fees related thereto, shall become due and payable on the
Availability Expiration Date, provided that the Revolving Credit Loans may be
converted to Term Loans subject to the satisfaction by the Borrower of the
requirements of Section 2.10.

           (e) The entire outstanding principal amount of the Term Loans,
together with all accrued and unpaid interest thereon, shall become due and
payable on the Term Loan Maturity Date.

           SECTION II.14. Payment Procedures.

           (a) The Borrower hereby authorizes the Agent to charge the Borrower
with the amount of all interest, fees, expenses and other payments to be made
hereunder and under the other Loan Documents by adding such amount to the
Obligations. The Agent may, but shall not be obligated to, discharge the
Borrower's payment obligations hereunder by so increasing the amount of the
Obligations.

           (b) Whenever any payment or other transfer of funds to be made
hereunder shall be stated to be due or made on a day that is not a Business Day,
such payment or transfer may be made on the next succeeding Business Day, and,
if applicable, such extension of time shall be included in the computation of
the amount of interest due hereunder.

           SECTION II.15. Collection of Receivables; Application of Collections;
Deposit to Blocked Account.

           (a) The Borrower and CHI Finance shall maintain the Depository
Accounts in accordance with the terms of the Depository Account Agreement, to
which the Borrower and CHI Finance shall, except as provided in Section 9.3,
remit all Collections. CHI Finance shall maintain the Blocked Account in
accordance with the terms of the Blocked Account Agreement. All Collections, in
addition to all other cash received by the Borrower and CHI Finance from any
other source including, without limitation, all cash dividends, partnership or
similar distributions and other similar forms of payment made on account of
equity interests, shall promptly upon receipt be deposited into the Depository
Accounts (with the allocation of deposits between the two Depository Accounts to
be made in the reasonable discretion of the Borrower). On the last Business Day
of each month, the aggregate amount of all funds in the Depository Accounts in
excess of $3,000,000 shall be wire transferred to the Blocked Account for
application under Section 2.15(b).

           (b) Until the Availability Expiration Date, the Agent shall, so long
as no Event of Default has occurred and is continuing, instruct the Blocked
Account Bank to disburse on the first Business Day of each month amounts held in
the Blocked Account (to the extent the disbursement of such amounts would not
cause the aggregate amount of the outstanding principal balance of the Revolving
Credit Loans plus the aggregate amount of all outstanding Letters of Credit plus
the Interest Reserve to exceed $35,000,000 in the following order of priority:

                      (i) first, for deposit into the Depository Accounts (with
           the allocation of deposits between the

                                      -43-
<PAGE>

           two Depository Accounts to be made in the reasonable discretion of
           the Borrower) an aggregate amount, based on evidence satisfactory to
           the Agent submitted to it by the Borrower (including, without
           limitation, the reports specified in Section 7.1(k)(iii) and the
           statements specified in Section 7.1(k)(iv)) necessary to restore the
           aggregate balances in the Depository Accounts to $3,000,000, after
           giving effect to all Collections received by the Borrower and CHI
           Finance and deposited by them in the Depository Accounts in the
           preceding month;

                      (ii) second, to be applied to the payment of accrued and
           unpaid fees and expenses payable to the Agent under or in connection
           with this Agreement and the other Loan Documents;

                      (iii) third, to be ratably applied to the payment of
           accrued and unpaid interest, fees and expenses payable to the Lenders
           under or in connection with this Agreement and the other Loan
           Documents; and

                      (iv) fourth, to be ratably applied to the payment of such
           portion of the principal amount of the Revolving Credit Loans then
           outstanding, if any, as the Borrower requests in writing.

Amounts remaining unapplied in the Blocked Account on the first Business Day of
each month shall be invested in a manner similar to that provided in Section
2.12(c). Notwithstanding anything to the contrary set forth above, upon the
occurrence and during the continuance of an Event of Default, the Agent may
apply any and all such amounts for deposit in the L/C Cash Collateral Account or
for ratable payment of such of the Obligations and in such order as it may elect
in its sole and absolute discretion.

           (c) Commencing on the Availability Expiration Date, subject to
Section 8.3, the Agent shall, so long as no Event of Default has occurred and is
continuing, instruct the Blocked Account Bank to disburse on the first Business
Day of each month amounts held in the Blocked Account in the following order of
priority:

                      (i) first, for deposit into the Depository Accounts (with
           the allocation of deposits between the two Depository Accounts to be
           made in the reasonable discretion of the Borrower), an aggregate
           amount, based on evidence satisfactory to the Agent submitted to it
           by the Borrower (including, without limitation, the reports specified
           in Section 7.1(k)(iii) and the statements specified in Section
           7.1(k)(iv)) necessary to restore the aggregate balances in the
           Depository Accounts to $3,000,000, after giving effect to all
           Collections received by the Borrower and CHI Finance deposited in the
           Depository Accounts in the preceding month;

                                      -44-
<PAGE>

                      (ii) second, to be applied to the payment of accrued and
           unpaid fees and expenses payable to the Agent under or in connection
           with this Agreement and the other Loan Documents;

                      (iii) third, to be applied ratably to the ratable payment
           of accrued and unpaid interest, fees and expenses payable to the
           Lenders under or in connection with this Agreement and the other Loan
           Documents;

                      (iv) fourth, to be applied ratably to the payment or
           prepayment, as the case may be, of the principal amount then due
           under the Term Loans;

                      (v) fifth, to be applied ratably to prepay such portion of
           the principal amount of the Term Loans then outstanding, if any, as
           the Borrower requests in writing; and

                      (vi) sixth, if the Term Loans have been paid in full, to
           be deposited in the L/C Cash Collateral Account to the extent
           required by Section 2.12(a).

Amounts remaining unapplied in the Blocked Account on the first Business Day of
each month shall be invested in a manner similar to that provided in Section
2.12(c). Notwithstanding anything to the contrary set forth above, upon the
occurrence and during the continuance of an Event of Default, the Agent may
apply any and all such amounts for deposit in the L/C Cash Collateral Account or
for payment of such of the Obligations and in such order as it may elect in its
sole and absolute discretion.

                                    --------

           SECTION III.1. General. As security for all of the Obligations, the
Borrower hereby reaffirms, ratifies and grants to the Agent for the ratable
benefit of the Lenders a Lien on all of its right, title and interest in and to
Receivables, other than Restricted Receivables, Inventory, Equipment and (except
as specified below) all other property in all of its forms, tangible and
intangible, wherever located and whether now owned or hereafter acquired, and
all additions and accessions thereto and substitutions and replacements therefor
and improvements thereon, and all proceeds (whether or not cash) and products
thereof including, without limitation, all proceeds of insurance covering the
same and all tort claims in connection therewith, provided that the Borrower (i)
shall be deemed to have granted the Agent for the ratable benefit of the Lenders
a Lien on its right, title and interest in and to each of its Receivables that
no longer constitute Restricted Receivables immediately upon the date that each
such Receivable becomes so unrestricted and (ii) has granted to the Agent for
the ratable benefit of the Lenders a Lien only on the capital stock or other
equity interests of the Borrower in the Pledged Subsidiaries. As further
security for the Obligations, and to provide other assurances to the Agent and
the Lenders, the Agent acknowledges receipt, for the ratable benefit of the
Lenders, of, among other things:

                                      -46-

           (c)        the Blocked Account Agreement; and

           SECTION III.2. Further Security. The Borrower also grants to the
Agent for the ratable benefit of the Lenders, as further security for all of the
Obligations, a security interest in all of its right, title and interest in and
to all property of the Borrower in the possession of or deposited with or in the
custody of the Agent, any Lender, or any Affiliate of the Agent or any Lender,
or any representative, agent or correspondent of the Agent or any Lender and in
all present and future deposit accounts (as that term is defined in the Code)
including, without limitation, the Depository Accounts, the Blocked Account and
the L/C Cash Collateral Account. For purposes of this Agreement, any property in
which the Agent, any Lender or any such Affiliate has any security or title
retention interest shall be deemed to be in the custody of the Agent, such
Lender or of such Affiliate.

           SECTION III.3. Termination. Upon (i) the termination of this
Agreement and the indefeasible payment in full of all Obligations and (ii) (A)
the acknowledgment in writing of all beneficiaries of Letters of Credit as to
the termination of each Letter of Credit or (B) the deposit in the L/C Cash
Collateral Account of an amount not less than 105% of the aggregate then undrawn
amount of the outstanding Letters of Credit, the Agent shall promptly deliver to
the Borrower upon the Borrower's request and at the Borrower's expense, releases
and satisfactions of all financing statements, notices of assignment and other
registrations of security and the Borrower shall deliver to the Agent and the
Lenders a general release of all of the Agent's and the Lenders' liabilities and
obligations under all Loan Documents and an acknowledgment that the same have
been terminated (except for (a) those provisions which are expressly stated to
survive the termination of this Agreement and (b) any obligations with respect
to outstanding Letters of Credit secured by cash collateral). For purposes of
this Section 3.3, the Obligations shall be deemed to be indefeasibly paid in
full (a) if the Borrower (or, if final payment is made by another Person, such
other Person) is Solvent on the date of such payment, after giving effect
thereto or (b) in all other cases, ninety-one days after such final payment in
full.

           SECTION III.4. Recourse to Security. Recourse to security shall not
be required for any Obligation hereunder and the Borrower hereby waives any
requirement that the Agent exhaust any right or take any action against any of
the Collateral before proceeding to enforce the Obligations against the
Borrower.

           SECTION III.5. Special Provisions Relating to Receivables and Related
Matters.

           (a) Receivables Documents. Upon the occurrence and continuance of an
Event of Default, the Borrower shall deliver to the Agent the following, all in
form, content and scope satisfactory to the Agent:

                      (i) (A) copies or the originals of each signed note,
           letter of credit or other instrument for the payment of money which
           evidences a Receivable of the Borrower, (B) any power therefor
           executed in blank, duly endorsed to the order of the Agent, and (C) a
           schedule listing its Receivables so evidenced; and

                      (ii) such endorsements or assignments of its Receivables
           and other information relating to the Receivables of the Borrower as
           the Agent may from time to time reasonably request, and the originals
           of any such document or instrument, including, without limitation,
           those referred to in clause (i) above, delivered to the Agent shall
           be held as collateral by the Agent.

           (b) Disputes. Except in the ordinary course of business, the Borrower
shall not, from and after the Closing Date, settle or adjust any Receivable, or
grant any credit or allowance with respect thereto, except, so long no Event of
Default has occurred and is continuing, the Borrower may settle or adjust
Receivables, or grant such credits or allowances, involving a disputed amount
not to exceed $1,000,000 in the aggregate, without the Required Lenders'
consent. The Agent may, with the consent of the Required Lenders (if sought by
the Agent), following the occurrence and continuance of an Event of Default and
after giving written notice of its intent to act in accordance herewith, settle
or adjust disputes or claims directly with account debtors for amounts and upon
terms which it considers advisable.

fair market value in excess of $50,000, now owned or hereafter acquired, will be

more than sixty days to a location not specified in such Schedule unless the
Borrower has given the Agent at least thirty days' prior written notice thereof
and the Required Lenders have given their prior written consent thereto, which
shall not be unreasonably withheld or delayed. In no event shall any Equipment
be moved outside the United States or Canada. The Borrower shall at all times
hereafter keep correct and accurate records itemizing and describing the
location, kind, type, age and condition of Equipment, the Borrower's cost
therefor and accumulated depreciation thereof and retirements, sales, or other
dispositions thereof, all of which records shall be available on demand during
the Borrower's usual business hours to any of the officers, employees or agents
of the Agent.

           (b) Repair. The Borrower shall keep all of its Equipment in good
repair and good operating condition in accordance with industry standards in all
material respects (normal wear and tear excepted), and will make all repairs and
replacements when and where necessary and practical, consistent with the
then-current Business Plan, will not waste or destroy it or any part thereof,
and will not be negligent in the care or use thereof. The Borrower shall repair
and maintain all Equipment in accordance with industry practices in all material
respects and in a manner sufficient to continue the operation of its business as
heretofore conducted. The Borrower shall keep accurate lists and records of all
the Equipment. The Equipment shall be used in accordance with law and the
manufacturer's instructions and shall be kept separate from and shall not be
annexed or affixed to or become part of any Property or any other realty.

           (c) Disposal. Where the Borrower is permitted to dispose of any
Equipment under this Agreement or by any consent thereto hereafter given by the
Required Lenders, the Borrower shall do so at arm's length, in good faith and by
obtaining the maximum amount of recovery practicable therefor and without
impairing the operating integrity or value of the remaining Equipment in any
material respect.

ratable benefit of the Lenders interest on the Loans calculated monthly in

and of the Lenders to purchase participations in Letters of Credit or to make
Revolving Credit Loans, terminate pursuant to Section 9.2(b), in each case prior

           SECTION IV.9. Indemnification in Certain Events. If, after the
Closing Date, either (i) any change in or in the interpretation of any law or
regulation is introduced, including, without limitation, with respect to reserve
requirements, applicable to any of the Lenders or any other banking or financial
institution from which any of the Lenders borrows funds or obtains credit, (ii)
any of the Lenders complies with any future guideline or request from any
central bank or other Governmental Authority or (iii) any of the Lenders
determines that the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof has or would
have the effect described below, or any of the Lenders complies with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, and in the case of any
event set forth in this clause (iii), such adoption, change or compliance has or
would have the direct or indirect effect of reducing the rate of return on any
of the Lender's capital as a consequence of its obligations hereunder to a level
below that which such Lender could have achieved but for such adoption, change
or compliance (taking into consideration such Lender's policies as the case may
be with respect to capital adequacy) by an amount deemed by such Lender to be
material, and any of the foregoing events described in clauses (i), (ii) and
(iii) increases any Lender's cost of funding or maintaining the Loans, or
reduces the amount receivable in respect thereof by any of the Lenders, then the
Borrower shall, upon demand by the Agent, pay to the Agent for the account of
the applicable Lender additional amounts sufficient to indemnify such Lender
against such increase in cost or reduction in amount receivable. Upon the
occurrence of any event giving rise to the application of this Section involving
an amount in excess of $25,000 in the aggregate, or $10,000 per Lender, the
applicable Lender shall, if requested by the Borrower, use reasonable efforts to
avoid or minimize the increase of costs or reduction in the amount receivable
resulting from such event so long as such avoidance or minimization can be made
in such a manner that such Lender, in its sole determination, suffers no
economic, legal or regulatory disadvantage.

           operation by it or any Affiliate of any Facility or otherwise) is
           subject to any type of financial, organizational or rate regulation
           as an Electric Utility or to be regulated as a "public utility
           company" or a company which is a "holding company" of a "public
           utility company" subject to registration with the Securities and
           Exchange Commission or to regulation under PUHCA.

                      (ii) Neither the Agent or the Lenders, nor any of their
           Affiliates will, solely (i.e., without regard to any other activity
           or operation) by reason of this Agreement and the other Loan
           Documents and the consummation of the transactions contemplated
           hereby and thereby, be or deemed to be, or subject to regulation as a
           "public utility company" or a company which is a "holding company" of
           a "public utility company" subject to registration with the
           Securities and Exchange Commission or to regulation under PUHCA or

           power procedures.

                      (iii) Each Facility owned by the Borrower or any of its
           Affiliates on the Closing Date is (A) a "qualifying facility" within

           generator" under the National Energy Policy Act of 1992 or (B) exempt

           required solely for the use by the Borrower of net operating loss
           carryforwards, no extension of a statute of limitations relating to
           taxes, assessments, fees or other governmental charges is in effect

           the exercise of its remedies hereunder or under applicable law the
           Agent or any of the Lenders obtains control of any Facility and thus
           becomes subject to regulation as the owner of a "qualifying facility"
           as defined under the PURPA regulations, or as an "exempt wholesale
           generator" as defined under the National Energy Policy Act of 1992.

           Subsidiary in writing of such failure, provided that, if (I) such
           failure is capable of being cured within such thirty-day period and
           (II) the Borrower or such Subsidiary initiates a cure thereof within
           such period, it shall not become an Event of Default unless it
           continues to exist on the earlier of (x) the Borrower or such

           a party (except as provided in Section 9.1(a), (b)(i) or(b)(ii)),
           provided that, if such failure (A) was unintentional, (B) could not
           reasonably be expected to have a Material Adverse Effect and (C) is
           capable of being cured within thirty days, it shall not become an
           Event of Default unless it continues to exist at the end of such
           thirty-day period; or

periods) or by required prepayment, acceleration, demand or otherwise), or (ii)
shall otherwise be in breach or default in any of its obligations under any
agreement with respect to any such Indebtedness, if the effect of such breach,
default or failure to pay is to cause such Indebtedness to become due or
redeemed or permit the holder or holders of such Indebtedness (or a trustee or
agent on behalf of such holder or holders) to declare such Indebtedness due or
require such Indebtedness to be redeemed prior to its stated maturity; or

provided a substitute therefor which is reasonably acceptable to the Agent
within ten days of written notice thereof to the Borrower; the Borrower or any

           (c) Blocked and Depository Accounts. Notify the Blocked Account Bank
and the Depository Account Bank to deliver to the Agent for application to the

           (d) Cash Collateralization. With respect to all Letters of Credit
outstanding at the time of an acceleration pursuant to Section 9.2(a), or within

(o), require the Borrower to deposit in the L/C Cash Collateral Account an
amount equal to the aggregate then undrawn amount of the outstanding Letters of

dominion and control of the Agent and shall be applied by the Agent to the
payment of drafts drawn under such Letters of Credit, and the balance, if any,
in the L/C Cash Collateral Account, after all such Letters of Credit shall have
expired or been fully drawn upon, shall be applied to repay the other
Obligations. After all such Letters of Credit shall have expired or been fully
drawn upon, all Obligations in respect of Letters of Credit shall have been

if any, in the L/C Cash Collateral Account shall be returned to the Borrower.

           SECTION IX.3. Other Remedies. In addition to those remedies set forth

Default, the Agent shall have all rights and remedies with respect to the
Obligations and the Collateral under the Code, other applicable laws and the
Loan Documents, and the Agent may do any or all of the following:

           (a) have full access to all documents, instruments, files and records
(including the copying of any computer records) relating to the Receivables of
the Borrower or use (at the expense of the Borrower) such supplies or space of
the Borrower at the Borrower's places of business necessary to administer and
collect its Receivables, other than Restricted Receivables;

           (b) accelerate or extend the time of payment, compromise, issue
credits, or bring suit on the Receivables, other than Restricted Receivables, of
the Borrower (in the name of the Borrower or the Agent) and otherwise administer
and collect such Receivables;

                                      -96-
<PAGE>

           (c) sell, assign and deliver the Receivables of the Borrower, other
than Restricted Receivables, and any returned, reclaimed or repossessed
merchandise, with or without advertisement, at public or private sale, for cash,
on credit or otherwise, subject to applicable law;

           (d) foreclose the security interests created pursuant to the Loan
Documents by any available procedure, or take possession of any or all of the
Collateral, without judicial process and enter any premises where any Collateral
may be located for the purpose of taking possession of or removing the same; and

           (e) make any payment or take any other action necessary or desirable
to protect or preserve any Collateral, any of the Facilities or any other aspect
of the business of the Borrower or any of its Subsidiaries including, without
limitation, the maintenance of permits, rights of way, easements and licenses
relating to the Facilities or otherwise to the business activities of the
Borrower and paying on behalf of the Borrower or such Subsidiary insurance
premiums, tax obligations or any other liabilities which, if unpaid, could
result in the creation of a Lien on any of the Collateral or reasonably be
expected to have a Material Adverse Effect, all of which payments shall be
Obligations and secured by the Collateral, provided that nothing herein shall be
deemed to create any obligation on the part of the Agent to make any of the
foregoing payments or to take any other action.

To the extent permitted by applicable law, the Agent may bid or become a
purchaser at any sale, free from any right of redemption, which right is
expressly waived by the Borrower. If notice of intended disposition of any
Collateral is required by law, it is agreed that five Business Days' notice
shall constitute reasonable notification. The Borrower will assemble the
Collateral and make it available to the Agent at such locations as the Agent may
specify, whether at the premises of the Borrower or elsewhere, and will make
available to the Agent the premises and facilities of the Borrower for the
purpose of the Agent's taking possession of or removing the Collateral or
putting the Collateral in saleable form.

           SECTION IX.4. License for Use of Software and Other Intellectual
Property. Unless expressly prohibited by any licensor thereof, the Agent is
hereby granted a license to use all computer software programs, data bases,
processes and materials used by the Borrower in connection with its businesses
or the Collateral. The Agent agrees not to use any such license prior to the
occurrence of an Event of Default without giving the Borrower prior notice
thereof.

<PAGE>

           SECTION IX.5. No Marshalling; Deficiencies; Remedies Cumulative. The
Borrower waives any right to require the Agent to marshal any Collateral or
otherwise to compel the Agent to seek recourse against or satisfaction of the
Obligations from one source before seeking recourse or satisfaction from another
source. The net cash proceeds resulting from the Agent's exercise of any of the
foregoing rights to liquidate all or substantially all of the Collateral (after
deducting all of the Agent's expenses related thereto) shall be applied by the
Agent to the payment of the Obligations, whether due or to become due, in such
order as the Agent may elect. The Borrower shall remain liable to the Agent and
the Lenders for any deficiencies and the Agent and the Lenders in turn agree to
remit to the Borrower or its successors or assigns any surplus resulting
therefrom. The foregoing remedies are not intended to be exhaustive and the full
or partial exercise of any of them shall not preclude the full or partial
exercise of any other available remedy under this Agreement, under any other
Loan Document, at equity or at law.

                                      -98-

           SECTION IX.6. Defense of Collateral; Continuation of Liens; Further
Assurances. The Borrower shall defend the Collateral against all claims and
demands of all Persons at any time claiming any interest therein, other than
Permitted Liens. The Borrower agrees to comply with the requirements of all
state and federal laws to grant to and continue in favor of the Agent for the
ratable benefit of the Lenders valid and perfected first security interests in
the Collateral. The Borrower agrees, from time to time, at the Agent's request,
to file notices of Liens, financing statements, and amendments, renewals and
continuations thereof, and cooperate with the Agent's representatives, in
connection with the continued perfection and protection of the Collateral. The
Borrower shall do all things and shall deliver all instruments reasonably
requested by the Agent to protect or perfect any security interest, pledge,
mortgage or lien given hereunder including, without limitation, financing
statements under the Code. The Borrower authorizes the Agent (i) to execute
alone any financing statement or other documents or instruments that the Agent
may reasonably require to perfect, protect or establish any Lien or security
interest hereunder, (ii) to sign the Borrower's name on the same and (iii) to
file this Agreement or any copy thereof as a financing statement, where
permitted by law. The Borrower appoints such Person or Persons as the Agent may
designate as its attorney-in-fact and upon the occurrence and continuance of an
Event of Default, such attorney-in-fact may endorse the name of the Borrower on
any checks, notes, drafts or other forms of payment or security that may come
into the possession of either the Agent or any Affiliate of the Agent to sign
the Borrower's name on invoices or bills of lading, drafts against customers,
notices of assignment, verifications and schedules and, generally, to do all
things necessary to carry out this Agreement. Upon the occurrence and
continuance of an Event of Default, such attorney-in-fact may notify the post
office authorities to change the address of delivery of mail to the then
existing address of the Borrower to an address designated by the Agent, and open
and dispose of mail addressed to the Borrower. The powers granted herein, being
coupled with an interest, are irrevocable, and the Borrower approves and
ratifies all acts of the attorney-in-fact. Neither the Agent nor the
attorney-in-fact shall be liable for any act or omission, error in judgment or
mistake of law so long as such act, omission, error or mistake does not
constitute intentional misconduct or gross negligence.

                                    THE AGENT
                                    ---------

           SECTION X.1. Appointment of Agent.

           (a) Each Lender hereby designates HUB as its Agent and irrevocably
authorizes the Agent to take action on such Lender's behalf under the Loan
Documents as is provided herein and to exercise the powers and to perform the
duties described therein and to exercise such other powers as are reasonably
incidental thereto. The Agent may perform any of its duties by or through its
agents or employees.

           (b) Other than the Borrower's rights under Section 10.9, the
provisions of this Article X are solely for the benefit of the Agent and the
Lenders, and the Borrower shall not have any rights as a third party beneficiary
of any of the provisions hereof. The Agent shall act solely as agent of the
Lenders and assumes no obligation toward or relationship of agency or trust with
or for the Borrower.

           SECTION X.2. Nature of Duties of Agent. The Agent shall have no
duties or responsibilities except those expressly set forth in the Loan
Documents. Neither the Agent nor any of its officers, directors, employees or
agents shall be liable for any action taken or omitted by it as such hereunder
or in connection herewith, unless caused by its or their gross negligence or
willful misconduct. The duties of the Agent shall be mechanical and
administrative in nature. The Agent does not have a fiduciary relationship in
respect of any Lender or any participant of any Lender.

           SECTION X.3. Lack of Reliance on Agent.

           (a) Independently and without reliance upon the Agent, each Lender,
to the extent it deems appropriate, has made and shall continue to make (i) its
own independent investigation of the financial or other condition and affairs of
the Borrower in connection with the taking or not taking of any action in
connection herewith and (ii) its own appraisal of the creditworthiness of the
Borrower, and, except as expressly provided in this Agreement, the Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information with respect thereto,
whether coming into its possession before the making of the initial Revolving
Credit Loans or the issuance of the Initial Letter of Credit or at any time or
times thereafter.

<PAGE>

           (b) The Agent shall not be responsible to any Lender for any
recitals, statements, information, representations or warranties herein or in
any document, certificate or other writing delivered in connection herewith or
for the execution, effectiveness, genuineness, validity, enforceability,
collectability, priority or sufficiency of this Agreement or the Notes or the
financial or other condition of the Borrower. The Agent shall not be required to
make any inquiry concerning either the performance or observance of any of the
terms, provisions or conditions of this Agreement or the Notes, or the financial
condition of the Borrower, or the existence or possible existence of any Default
or Event of Default, unless specifically requested to do so in writing by any
Lender.

           SECTION X.4. Certain Rights of the Agent. The Agent may request
instructions from the Required Lenders at any time. If the Agent requests
instructions from the Required Lenders with respect to any action or inaction,
the Agent shall be entitled to await instructions from the Required Lenders
before such action or inaction. No Lender shall have any right of action based
upon the Agent's action or inaction in response to instructions from the
Required Lenders.

           SECTION X.5. Reliance by Agent. The Agent may rely upon written or
telephonic communication it believes to be genuine and to have been signed, sent
or made by the proper person. The Agent may obtain the advice of legal counsel
(including counsel for the Borrower with respect to matters concerning the
Borrower), independent public accountants and other experts selected by it and
shall have no liability for any action or inaction taken or omitted to be taken
by it in good faith based upon such advice.

           SECTION X.6. Indemnification of Agent. To the extent the Agent is not
reimbursed and indemnified by the Borrower, each Lender will reimburse and
indemnify the Agent to the extent of its Proportionate Share for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including, without limitation, counsel fees and disbursements)
or disbursements of any kind or nature whatsoever which may be imposed on,
incurred by or asserted against the Agent in performing its duties hereunder or
otherwise relating to the Loan Documents unless resulting from the Agent's gross
negligence or willful misconduct. The agreements contained in this Section shall
survive any termination of this Agreement and the other Loan Documents and the
payment in full of the Obligations.

           SECTION X.7. The Agent in Its Individual Capacity. In its individual
capacity, the Agent shall have the same rights and powers hereunder as any other
Lender or holder of a Note or participation interests and may exercise the same
as though it was not performing the duties specified herein. The terms
"Lenders," "Required Lenders," "holders of Notes," or any similar terms shall,
unless the context clearly otherwise indicates, include the Agent in its
individual capacity. The Agent and its Affiliates may accept deposits from, lend
money to, acquire equity interests in, and generally engage in any kind of
banking, trust, financial advisory or other business with the Borrower or any
Affiliate of the Borrower as if it were not performing the duties specified
herein, and may accept fees and other consideration from the Borrower for
services in connection with this Agreement and otherwise without having to
account for the same to the Lenders. The Lenders hereby acknowledge that (i) HUB
has certain lending relationships with Subsidiaries of the Borrower and (ii) the
Borrower has agreed to pay to HUB, for its own account, certain fees in
connection with the issuance of Letters of Credit from time to time by HUB for
the account of the Borrower or its Subsidiaries.

           SECTION X.8. Holders of Notes. The Agent may deem and treat the payee
of any Note as the owner thereof for all purposes hereof unless and until a
written notice of the assignment or transfer thereof shall have been filed with
the Agent. Any request, authority or consent of any Person who, at the time of
making such request or giving such authority or consent, is the holder of any
Note, shall be conclusive and binding on any subsequent holder, transferee or
assignee of such Note or of any Note or Notes issued in exchange therefor.

           SECTION X.9. Successor Agent.

           (a) The Agent may, upon ten Business Days' notice to the Lenders and
the Borrower, resign by giving written notice thereof to the Lenders and the
Borrower. The Agent's resignation shall be effective upon the appointment of a
successor Agent.

                                     -102-
<PAGE>

           (b) Upon receipt of the Agent's resignation, the Required Lenders may
appoint a successor Agent which shall also be a Lender. Unless an Event of
Default shall have occurred and be continuing at the time of such appointment,
any successor Agent shall be subject to approval by the Borrower, which approval
shall not be unreasonably withheld and shall be delivered to the Required
Lenders within ten Business Days after the Borrower's receipt of notice of a
proposed successor Agent. If a successor Agent has not accepted its appointment
within fifteen Business Days, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent in compliance with the preceding sentence.

           (c) Upon its acceptance of the agency hereunder, such successor Agent
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Agent, and the retiring Agent shall be discharged from
its duties and obligations under this Agreement. The retiring Agent shall
continue to have the benefit of this Article X for any action or inaction while
it was Agent.

           SECTION X.10. Collateral Matters.

           (a) The Agent is authorized to release any Lien granted to or held by
the Agent upon any Collateral (i) upon termination of the Revolving Credit
Commitments, expiration of all outstanding Letters of Credit and payment and
satisfaction of all of the Obligations, (ii) required to be delivered from
permitted sales of Collateral hereunder, if any, upon receipt of the proceeds or
(iii) if the release can be and is approved by the Required Lenders. The Agent
may request and the Lenders will provide confirmation of the Agent's authority
to release particular types or items of Collateral.

                                     -103-
<PAGE>

           (b) Upon any sale and transfer of Collateral which is expressly
permitted pursuant to the terms of this Agreement, or consented to in writing by
the Required Lenders or all of the Lenders, as applicable, and upon at least
five Business Days' prior written request by the Borrower, the Agent shall (and
is hereby irrevocably authorized by the Lenders to) execute such documents as
may be necessary to evidence the release of the Liens granted to the Agent for
the benefit of the Lenders herein or pursuant hereto upon the Collateral that
was sold or transferred; provided that (i) the Agent shall not be required to
execute any such document on terms which, in the Agent's opinion, would expose
the Agent to liability or create any obligation or entail any consequence other
than the release of such Liens without recourse or warranty and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens upon (or obligations of the Borrower or any other Pledgor in respect
of) all interests retained by the Borrower or any Pledgor, including (without
limitation) the proceeds of the sale, all of which shall continue to constitute
part of the Collateral. In the event of any sale or transfer of Collateral, or
any foreclosure with respect to any of the Collateral, the Agent shall be
authorized to deduct all of the expenses reasonably incurred by the Agent from
the proceeds of any such sale, transfer or foreclosure.

           (c) The Agent shall have no obligation to assure that the Collateral
exists or is owned by the Borrower or any other Pledgor, that such Collateral is
cared for, protected or insured, or that the Liens on the Collateral have been
created, perfected or have any particular priority. With respect to the
Collateral, the Agent may act in any manner it may deem appropriate, in its sole
discretion, given the Agent's own interest in the Collateral as one of the
Lenders and it shall have no duty or liability whatsoever to the Lenders, except
for its gross negligence or willful misconduct.

           SECTION X.11. Actions with Respect to Defaults. In addition to the
Agent's right to take actions on its own accord as permitted under this
Agreement, the Agent shall take such action with respect to an Event of Default
as shall be directed by the Required Lenders. Until the Agent shall have
received such directions, the Agent may act or not act as it deems advisable and
in the best interests of the Lenders.

                                     -104-

           SECTION X.12. Delivery of Information. The Agent shall not be
required to deliver to any Lender originals or copies of any documents,
instruments, notices, communications or other information received by the Agent
from the Borrower, any Subsidiary, the Required Lenders, any Lender or any other
Person under or in connection with this Agreement or any other Loan Document
except (i) as specifically provided in this Agreement or any other Loan Document
and (ii) as specifically requested from time to time in writing by any Lender
with respect to a specific document, instrument, notice or other written
communication received by and in the possession of the Agent at the time of
receipt of such request and then only in accordance with such specific request.

Agent and the Required Lenders.

           (b) Lender Assignments. Each Lender may, with the prior consent of
the Agent and the Borrower which, except as provided in the penultimate sentence
of this subsection (b), shall not be unreasonably withheld or delayed, assign to
one or more banks or other financial institutions all or a portion of its rights
and obligations under this Agreement, the Notes and the other Loan Documents,
and upon execution and delivery to the Agent, for its acceptance and recording
in the Register, of an agreement in substantially the form of Exhibit C (an
"Assignment and Assumption Agreement"), together with surrender of any Note or
Notes subject to such assignment and a processing and recordation fee of $2,500.
No such assignment shall be for less than $3,000,000 of the Revolving Credit
Commitments or Loans unless it is to another Lender. Any assignment by a Lender
hereunder shall include such Lender's Revolving Credit Loans, Revolving Credit
Commitment and Term Loan. Upon such execution and delivery to the Agent of an
Assignment and Assumption Agreement, from and after the date specified as the
effective date in the Assignment and Assumption Agreement (the "Acceptance

that rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Assumption Agreement, such assignee shall have the rights and
obligations of a Lender hereunder and (y) the assignor thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment and Assumption Agreement, relinquish its rights (other than
any rights it may have pursuant to Section 11.9 which will survive) and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption Agreement covering all or the remaining portion of an
assigning Lender's rights and obligations under this Agreement, such Lender
shall cease to be a party hereto). No consent of the Borrower shall be required
under the first sentence of this Section, (i) if an Event of Default has
occurred and is continuing, (ii) with respect to an assignment to a Lender, a
branch office of a Lender or an Affiliate of a Lender or (iii) with respect to a

Agreement, the Notes or the other Loan Documents to any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System or U.S. Treasury Regulation 31 CFR " 203.14, and such Federal Reserve
Bank shall be permitted to enforce such pledge in any manner permitted by
applicable law. If the Borrower's consent is required hereunder with respect to
an assignment by HUB other than in connection with a sale of a division, or
portfolio of assets, of the Lender, the Borrower may withhold such consent in
its sole and absolute discretion if, after giving effect to such assignment,
HUB's Proportionate Share would be less than 50.1%. In all cases where the
Borrower's consent to an assignment by a Lender is not required hereunder, the
Agent agrees to use reasonable efforts to give written notice of such assignment
to the Borrower promptly after its effectiveness, provided that the Agent's
failure to give such notice shall not invalidate or limit such assignment.

information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement, (v) such
assignee appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to the

           (d) Agent's Register. The Agent shall maintain a register of the
names and addresses of the Lenders, their Commitments and the principal amount
of their Loans (the "Register"). The Agent shall also maintain a copy of each
Assignment and Assumption Agreement delivered to and accepted by it and modify
the Register to give effect to each Assignment and Assumption Agreement. The
entries in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register and copies of each Assignment and
Assumption Agreement shall be available for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice. Upon its receipt of each Assignment and Assumption Agreement and
surrender of the affected Note or Notes subject to such assignment, the Agent
will give prompt notice thereof to the Borrower. Within five Business Days after
its receipt of such notice, the Borrower shall execute and deliver to the Agent
(i) before the Availability Expiration Date, a new Revolving Credit Note to the
order of the assignee in the amount of the Revolving Credit Commitment assumed
by it and to the assignor in the amount of the Revolving Credit Commitment
retained by it, if any, and (ii) after the Availability Expiration Date, a new
Term Note to the order of the assignee in the amount of the Term Loan assumed by
it and to the assignor in the amount of the Term Loan retained by it, if any.
Such new Note or Notes shall re-evidence the indebtedness outstanding under the
surrendered Note or Notes and shall be in an aggregate principal amount equal to
the aggregate principal amount of such surrendered Note or Notes and shall be
dated as of the Closing Date. The Agent shall be entitled to rely upon the
Register exclusively for purposes of identifying the Lenders hereunder.

(without the consent of the Agent, the Borrower or any other Lender) to one or
more parties in or to all or a portion of its rights and obligations under this
Agreement, the Notes and the other Loan Documents. Notwithstanding a Lender's
sale of a participation interest, such Lender's obligations hereunder shall
remain unchanged. The Borrower, the Agent, and the other Lenders shall continue
to deal solely and directly with such Lender. No participant shall have rights
to approve any amendment or waiver of this Agreement except to the extent such
amendment or waiver would (i) increase the Commitment of the Lender from whom
the participant purchased its participation interest; (ii) reduce the principal
of, or rate or amount of interest on the Loans subject to such participation
interest; (iii) postpone any date fixed for any payment of principal of, or
interest on, the Loans subject to such participation interest; or (iv) release
all or a substantial portion of the Collateral, other than in each case when
otherwise permitted hereunder.

           (f) Securities Laws. Each Lender agrees that, without the prior
written consent of the Borrower and the Agent, it will not make any assignment
hereunder in any manner or under any circumstances that would require
registration or qualification of, or filings in respect of, any Loan, Note or
other Obligation under the securities laws of the United States or of any other
jurisdiction.

           (g) Information. In connection with their efforts to assign their
rights or obligations or sell participations pursuant to Sections 11.8(b) and
(e) hereof, respectively, the Agent and the Lenders may disclose any information
they have, now or in the future, with respect to the business of the Borrower to

harmless the Agent and the Lenders, and its and their directors, officers,
agents, employees and counsel (each, an "Indemnified Party") from and against
any and all losses, claims, damages, liabilities, deficiencies, judgments or
expenses incurred by any of them (except to the extent that it is finally

Environmental Laws. In addition, the Borrower shall, upon demand, pay to the
Agent all costs and expenses incurred by the Agent (including, without

delivery, administration, modification and amendment of the Loan Documents, and,
upon the occurrence and during the continuance of an Event of Default, pay to

permissible under applicable law.

                                     -112-

           (b) The Borrower's obligations under Section 4.9 and this Section
11.9 shall survive any termination of this Agreement and the other Loan
Documents and the payment in full of the Obligations, and are in addition to,
and not in substitution of, any of its other obligations set forth in this
Agreement.

           SECTION XI.10. Right of Setoff. In addition to and not in limitation
of all rights of offset that the Agent, any Lender or any of their respective
Affiliates may have under applicable law, and whether or not the Agent has made
any demand or the Obligations of the Borrower have matured, the Agent, the
Lenders and their respective Affiliates shall have the right to appropriate and
apply to the payment of the Obligations of the Borrower all (i) deposits of the
Borrower or any of its Affiliates held by the Agent, any Lender or any of their
respective Affiliates and (ii) other obligations then or thereafter owing by the
Agent, any Lender or any of their respective Affiliates to the Borrower or any
of its Affiliates.

           SECTION XI.11. Amendments and Waivers.

           (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document shall be effective unless in writing and signed by the
Required Lenders (or signed by the Agent on their behalf after specific
authorization therefrom), determined without taking into account the Revolving
Credit Commitments or the Loans held by any Defaulting Lender, and any other
party to be charged thereby, except that:

                      (i) the consent of all the Lenders (other than any
           Defaulting Lender) is required to (A) reduce the principal of, or
           interest on, the Notes, any Letter of Credit reimbursement
           obligations or any fees hereunder (other than fees that are
           exclusively for the account of the Agent), (B) postpone the final
           scheduled date of maturity of the Notes or any date fixed for any
           payment in respect of interest on the Notes, any Letter of Credit
           reimbursement obligations or any fees hereunder, (C) amend or waive
           this Section 11.11(a), or change the definition of Required Lenders,
           or (D) release any Liens in favor of the Lenders on all or
           substantially all of the Collateral, except as otherwise expressly
           provided in this Agreement, and other than in connection with the
           financing, refinancing, sale or other disposition of any asset of the
           Borrower permitted under this Agreement;

                      (ii) no such amendment or waiver shall increase the
           Revolving Credit Commitment of any Lender over the amount thereof
           then in effect without the

                                     -113-
<PAGE>

           consent of such Lender (it being understood that amendments or
           waivers by the Required Lenders of conditions precedent, covenants,
           Defaults or Events of Default shall not constitute an increase in the
           Revolving Credit Commitment of any Lender, and that an increase in
           the available portion of any Revolving Credit Commitment of any
           Lender shall not constitute an increase in the Commitment of such
           Lender);

                      (iii) the consent of the Agent shall be required for any
           amendment, waiver or consent affecting the rights or duties of the
           Agent under any Loan Document, in addition to the consent of the
           Lenders otherwise required by this Section 11.11; and

                      (iv) the consent of the Borrower shall not be required for
           any amendment, modification or waiver of the provisions of Article X
           (other than Section 10.9).

           (b) The Borrower and the Lenders hereby authorize the Agent to modify
this Agreement by unilaterally amending or supplementing Schedule 1 to reflect
assignments of the Commitments.

           (c) If, in connection with any proposed amendment or waiver of any of
the provisions of this Agreement as contemplated by Section 11.11(a), the
consent of the Required Lenders is obtained but the consent of one or more of
such other Lenders whose consent is required is not obtained, then the Borrower
shall have the right to replace each such non-consenting Lender or Lenders (so
long as all non-consenting Lenders are so replaced) with one or more replacement
Lenders pursuant to Section 11.8 so long as at the time of such replacement,
each such replacement Lender consents to the proposed amendment or waiver. No
early termination fee shall be payable under Section 4.7 to any Lender that is
replaced under this subsection.

           SECTION XI.12. Nonliability of Agent and Lenders. The relationship
between the Borrower and the Lenders and the Agent shall be solely that of
borrower and lender. Neither the Agent nor any Lender shall have any fiduciary
responsibilities to the Borrower. Neither the Agent nor any Lender undertakes
any responsibility to the Borrower to review or inform the Borrower of any
matter in connection with any phase of the Borrower's business or operations.

<PAGE>

           SECTION XI.13. Independent Nature of Lenders' Rights. The amount
payable at any time hereunder to each Lender under such Lender's Note shall be a
separate and independent debt.

           SECTION XI.14. Counterparts; Telecopied Signatures. This Agreement
and any waiver or amendment hereto may be executed in counterparts and by the
parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all of which shall together constitute one
and the same instrument. This Agreement may be executed and delivered by
telecopier or other facsimile transmission all with the same force and effect as
if the same was a fully executed and delivered original counterpart.

           SECTION XI.15. Severability. In case any provision in or obligation
under this Agreement, the Notes or any other Loan Document shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining provisions or obligations, or of such provision
or obligation in any other jurisdiction, shall not in any way be affected or
impaired thereby.

                                     -115-
<PAGE>

           SECTION XI.16. Maximum Rate. Notwithstanding anything to the contrary
contained elsewhere in this Agreement or in any other Loan Document, the
Borrower, the Agent and the Lenders hereby agree that all agreements among them
under this Agreement and the other Loan Documents, whether now existing or
hereafter arising and whether written or oral, are expressly limited so that in
no contingency or event whatsoever shall the amount paid, or agreed to be paid,
to the Agent or any Lender for the use, forbearance, or detention of the money
loaned to the Borrower and evidenced hereby or thereby or for the performance or
payment of any covenant or obligation contained herein or therein, exceed the
maximum non-usurious interest rate, if any, that at any time or from time to
time may be contracted for, taken, reserved, charged or received on the
Obligations, under the laws of the State of New York (or the law of any other
jurisdiction whose laws may be mandatorily applicable notwithstanding other
provisions of this Agreement and the other Loan Documents), or under applicable
federal laws which may presently or hereafter be in effect and which allow a
higher maximum non-usurious interest rate than under New York (or such other
jurisdiction's) law, in any case after taking into account, to the extent
permitted by applicable law, any and all relevant payments or charges under this
Agreement and the other Loan Documents, and any available exemptions, exceptions
and exclusions (the "Highest Lawful Rate"). If due to any circumstance
whatsoever, fulfillment of any provisions of this Agreement or any of the other
Loan Documents at the time performance of such provision shall be due shall
exceed the Highest Lawful Rate, then, automatically, the obligation to be
fulfilled shall be modified or reduced to the extent necessary to limit such
interest to the Highest Lawful Rate, and if from any such circumstance the Agent
or any Lender should ever receive anything of value deemed interest by
applicable law which would exceed the Highest Lawful Rate, such excessive
interest shall be applied to the reduction of the principal amount then
outstanding hereunder or on account of any other then outstanding Obligations
and not to the payment of interest, or if such excessive interest exceeds the
principal unpaid balance then outstanding hereunder and such other then
outstanding Obligations, such excess shall be refunded to the Borrower. All sums
paid or agreed to be paid to the Agent or any Lender for the use, forbearance,
or detention of the Obligations and other Indebtedness of the Borrower to the
Lenders shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of such Indebtedness,
until payment in full thereof, so that the actual rate of interest on account of
all such Indebtedness does not exceed the Highest Lawful Rate throughout the
entire term of such Indebtedness. The terms and provisions of this Section shall
control every other provision of this Agreement and all agreements between the
Borrower, the Agent and the Lenders.

           SECTION XI.17. Amendment and Restatement. This Agreement amends and
restates, and supersedes in its entirety, the Original Loan Agreement.

           SECTION XI.18. ENTIRE AGREEMENT; SUCCESSORS AND ASSIGNS. THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE THE ENTIRE AGREEMENT AMONG THE
BORROWER, THE AGENT AND THE LENDERS, SUPERSEDE ANY PRIOR WRITTEN AND VERBAL
AGREEMENTS BETWEEN OR AMONG THEM, AND SHALL BIND AND BENEFIT THE BORROWER, THE
AGENT AND THE LENDERS AND THEIR RESPECTIVE SUCCESSORS AND PERMITTED ASSIGNS.
