                                LETTER OF CREDIT


SECTION 2.1       ISSUANCE OF LETTER OF CREDIT.

                  (a)      The Issuing Bank agrees to issue on the Date of
         Issuance, upon the terms, subject to the conditions and relying upon
         the representations and warranties set forth in this Agreement, the
         Letter of Credit substantially in the form of Exhibit A. The Letter of
         Credit shall be in the Original Stated Amount of $28,211,287.67 (the

         of the Bonds on the Date of Issuance, plus (ii) interest thereon at the

                  (b)      Effective upon the issuance of the Letter of Credit
         and without further action on the part of any Bank, each Participating
         Bank shall automatically acquire a participation in the Issuing Bank's
         liability under the Letter of Credit in an amount equal to such
         Participating Bank's Commitment Percentage of the Original Stated
         Amount.

SECTION 2.2       LETTER OF CREDIT DRAWINGS.

The Trustee is authorized to make drawings under the Letter of Credit in
accordance with the terms thereof. The Company hereby directs the Issuing Bank
to make payments under the Letter of Credit in the manner therein provided. The

Available Amount as provided in the Letter of Credit. No further consent of,
notice to or authorization by the Company shall be required in connection with
any such reinstatement occurring from time to time as contemplated hereby.

SECTION 2.3       COMPANY REIMBURSEMENT OBLIGATIONS; PARTICIPATING BANK PAYMENTS
IN RESPECT OF THE LETTER OF CREDIT; DRAWING LOANS.

                  (a)      L/C DISBURSEMENTS TO BE REIMBURSED IMMEDIATELY. On
         the day of (i) each L/C Disbursement on account of an Interest Drawing,
         and (ii) each other L/C Disbursement made when the conditions precedent
         contained in Section 3.2 are not true or have not been satisfied, the
         Company will pay to the Administrative Agent, for the account of the
         Participating Banks or the Issuing Bank, as the case may be, the full
         amount of such L/C Disbursement, without notice or demand of any kind.
         If the Company fails to make any such payment when due, the unpaid
         amount thereof shall bear interest until paid by the Company at the
         rate specified in Section 2.13.

                  (b)      OTHER L/C DISBURSEMENTS. Upon the occurrence of any
         L/C Disbursement not described in subsection (a), the Issuing Bank may
         request payment in the amount of such L/C Disbursement from the
         Participating Banks as provided in subsection (c). The amount so paid
         by each Participating Bank shall constitute a loan (a "DRAWING LOAN")
         to the Company by such Participating Bank, the proceeds of which
         Drawing Loan shall be remitted by the Participating Banks to the
         Administrative Agent and applied by the

                                      -9-
<PAGE>

         Administrative Agent or the Issuing Bank to the payment of the
         corresponding Reimbursement Obligation. Each Drawing Loan shall be due
         and payable on demand and shall bear interest on the unpaid principal
         amount thereof from the date such Drawing Loan is made until it is paid
         in full, at a rate per annum equal to the Unreimbursed Drawing Rate.

                  (c)      PAYMENTS BY PARTICIPATING BANKS. Upon any L/C
         Disbursement described in subsection (b), the Issuing Bank, directly or
         through the Administrative Agent, shall (and, at any time following any
         other L/C Disbursement, may) give each Participating Bank prompt notice
         (orally or in writing) of such L/C Disbursement, specifying (a) the
         amount of such L/C Disbursement, (b) the date such L/C Disbursement was
         or is to be made and (c) such Participating Bank's PRO RATA share of
         the amount of such L/C Disbursement (determined on the basis of such
         Participating Bank's Commitment Percentage). If so requested, each
         Participating Bank shall pay to the Administrative Agent, for the
         account of the Issuing Bank, an amount equal to such Participating
         Bank's Commitment Percentage of such L/C Disbursement, such payment to
         be made not later than 3:00 p.m. on the date on which such L/C
         Disbursement is made or to be made (if such Participating Bank was
         notified at or prior to 1:00 p.m. on such date) or on the next Business
         Day (if such Participating Bank was notified after such time). Each
         Participating Bank's obligation to make each such payment, and the
         right of the Administrative Agent and the Issuing Bank to receive the
         same, are absolute and unconditional and shall not be affected by any
         circumstance whatsoever, including (without limiting the effect of the
         foregoing or of Section 2.4) the occurrence or continuance of a
         Potential Default or Event of Default or the failure of any other
         Participating Bank to make any payment under this Section, and each
         Participating Bank further agrees that each such payment shall be made
         without any offset, abatement, withholding or reduction whatsoever.
         Each Participating Bank shall indemnify and hold harmless the
         Administrative Agent and the Issuing Bank from and against any and all
         losses, liabilities (including, without limitation, liabilities for
         penalties), actions, suits, judgments, demands, costs and expenses
         (including reasonable attorneys' fees) resulting from any failure of
         such Participating Bank to provide, or from any delay in providing, the
         Administrative Agent with such Participating Bank's Commitment
         Percentage of such L/C Disbursement in accordance with the provisions
         of this Section, but no Participating Bank shall be so liable for any
         such failure on the part of any other Participating Bank.

                  (d)      If any amount required to be paid by any
         Participating Bank to the Administrative Agent pursuant to Section
         2.3(c) in respect of any unreimbursed portion of any L/C Disbursement
         is made after the date such payment is due, such Participating Bank
         shall additionally pay to the Administrative Agent, for the account of
         the Issuing Bank, on demand, an amount equal to the product of (i) such
         amount, times (ii) the Applicable Rate, as defined below, times (iii) a
         fraction the numerator of which is the number of days during the period
         commencing on such due date and ending on the date on which payment is
         made (the "DELINQUENCY PERIOD") and the denominator of which is 360. As
         used in this subsection, "Applicable Rate" means (x) if the Delinquency
         Period is 3 days or less, the daily average Federal Funds Rate during
         the Delinquency Period, and (y) in all other cases, the daily average
         Base Rate during the Delinquency Period. A

                                      -10-
<PAGE>

         certificate of the Administrative Agent submitted to any Participating
         Bank with respect to any amounts owing under this subsection shall be
         conclusive in the absence of manifest error. For purposes of this
         subsection, payment by any Participating Bank to the Administrative
         Agent shall not be deemed made until such time as that payment is
         available to the Administrative Agent in immediately available funds.

                  (e)      Whenever, at any time after the Issuing Bank has made
         an L/C Disbursement and has received from any Participating Bank
         (through the Administrative Agent) that Participating Bank's PRO RATA
         share of such L/C Disbursement in accordance with section 2.3(c), the
         Administrative Agent receives any payment on account of such L/C
         Disbursement (whether or not such L/C Disbursement has been treated as
         a Drawing Loan under subsection (c), and whether such payment is
         received directly from the Company or otherwise, including proceeds of
         collateral applied thereto by the Issuing Bank), or any payment of
         interest on account thereof, the Administrative Agent will distribute
         to such Participating Bank that Participating Bank's L/C Commitment
         Percentage of such payment.

SECTION 2.4       AGREEMENT OF THE COMPANY AND EACH PARTICIPATING BANK.

Without limiting the effect of subsection 2.3, the Company and each
Participating Bank agree with the Issuing Bank that:

                  (a)      The Issuing Bank is authorized to make payments under
         the Letter of Credit upon the presentation of the documents provided
         for therein and without regard to whether the Company has failed to
         fulfill any of its obligations with respect to any Related Document or
         any other default has occurred thereunder.

                  (b)      The Issuing Bank is authorized to take such action on
         its behalf under the provisions of this Agreement and to exercise such
         powers and perform such duties as are specifically delegated to or
         required of the Issuing Bank by the terms hereof, together with such
         powers as are reasonably incidental thereto.

                  (c)      The Issuing Bank shall be entitled to rely upon any
         certificate, notice, demand or other communication (whether by cable,
         telegram, telecopy, S.W.I.F.T., telex or other written communication)
         believed by it to be genuine and to have been signed or sent by the
         proper Person or Persons (and no such reliance or failure shall place
         the Issuing Bank under any liability to the Company or any
         Participating Bank or limit or otherwise affect the Company's or any
         Participating Bank's obligations under this Agreement).

                  (d)      Any action, inaction or omission on the part of the
         Issuing Bank under or in connection with the Letter of Credit or the
         instruments or documents related thereto, if in good faith and in
         conformity with such laws, regulations or customs as the Issuing Bank
         may reasonably deem to be applicable, shall be binding upon the Company
         and each Participating Bank (and shall not place the Issuing Bank under
         any liability to the Company or any Participating Bank or limit or
         otherwise affect the Company's or any Participating Bank's obligations
         under this Agreement).

                                      -11-
<PAGE>

                  (e)      Notwithstanding any change or modification, with or
         without the consent of the Company, in any instruments or documents
         called for in the Letter of Credit, including waiver of noncompliance
         of any such instruments or documents with the terms of the Letter of
         Credit, this Agreement shall be binding on the Company with regard to
         the Letter of Credit and to any action taken by the Issuing Bank
         relative thereto.

                  (f)      The Company shall indemnify and hold harmless each
         Bank from any loss or expense arising from or in connection with the
         Letter of Credit (except to the extent that such loss or expense arises
         directly from the gross negligence or willful misconduct of the Issuing
         Bank).

SECTION 2.5       INTEREST RATES AND PAYMENT DATES.

Each Drawing Loan shall bear interest determined as follows (the "UNREIMBURSED
DRAWING RATE"):

                  (a)      through the third Business Day following the
         corresponding L/C Disbursement, at the Base Rate;

                  (b)      thereafter for the immediately following 6 Interest
         Periods, at a rate per annum equal to the LIBOR applicable to such
         Interest Periods, plus the Applicable Margin;

                  (c)      thereafter through the day preceding the first
         anniversary of such L/C Disbursement Date, at a rate per annum equal to
         the Base Rate; and

                  (d)      thereafter, at a rate per annum equal to the Base
         Rate plus 2%.

Interest on all Drawing Loans shall be payable on demand or, if demand is not
sooner made, on the last day of each calendar quarter.

SECTION 2.6       PAYMENTS.

                  (a)      To the extent the Administrative Agent actually
         receives payment in respect of principal of or interest on any Pledged
         Bond, the Drawing Loan made in connection with the purchase of such
         Pledged Bond shall be deemed to have been reduced PRO TANTO, with the
         Issuing Bank crediting any interest payment on the Pledged Bond
         received by it to the payment of interest on the related Drawing Loan
         (and, after payment of all interest accrued on the related Drawing
         Loan, to the payment of principal of the related Drawing Loan) and
         crediting any principal repayment received to the principal thereof
         (and, after payment of all principal of the related Drawing Loan, to
         the payment of interest accrued on the related Drawing Loan); PROVIDED
         that if such interests or principal payments on such Pledged Bonds are
         derived from the Letter of Credit, any such payments shall not be
         credited against the Drawing Loans unless the Company has fully
         reimbursed the Issuing Bank for such amounts derived from the Letter of
         Credit. Prior to the occurrence of an Event of Default the Issuing Bank
         agrees that any amount actually received by it in respect of principal
         of or interest on such Pledged Bonds and not credited to the payment of
         principal of or interest on the related Drawing Loan as

                                      -12-
<PAGE>

         provided in the preceding sentence shall be paid promptly to the
         Company unless such funds have been derived from a draw on the Letter
         of Credit which has not been fully reimbursed by the Company in which
         case only such amounts in excess of the amount necessary to fully
         reimburse the Issuing Bank for such payment from the Letter of Credit
         shall be returned to the Company. After the occurrence and during the
         continuance of an Event of Default any such excess shall be held as
         collateral for the Obligations pursuant to the terms of Section 6.2(a)
         and 6.3. Any such payment of a Drawing Loan will be subject, in the
         case of the first 180 days, to Section 2.16(a) hereof.

                  (b)      Each payment (including each prepayment) by the
         Company on account of principal of and interest on the Obligations
         payable to the Participating Banks hereunder shall be made PRO RATA
         according to the respective outstanding principal amounts of the
         Obligations then held by the Participating Banks. The Administrative
         Agent shall distribute such payments to the Participating Banks
         promptly upon receipt in like funds as received.

                  (c)      The Administrative Agent agrees that upon any payment
         of principal by the Company on a Drawing Loan (other than a payment
         deemed made pursuant to Section 2.6(a) above) the Administrative Agent
         will promptly thereafter direct the Trustee to transfer to the Company
         a corresponding amount of Pledged Bonds PROVIDED that the
         Administrative Agent shall only be obligated to transfer Pledged Bonds
         in an amount equal to Authorized Denominations.

                  (d)      Unless the Administrative Agent shall have received
         notice from the Company no later than 12:00 noon on the date on which
         any payment is due to the Participating Banks hereunder that the
         Company will not make such payment in full, the Administrative Agent
         may assume that the Company will make such payment in full to the
         Administrative Agent on such date and the Administrative Agent may, in
         reliance upon such assumption, cause to be distributed to each
         Participating Bank on such due date an amount equal to the amount then
         due such Participating Bank. If and to the extent the Company shall not
         have so made such payment in full to the Administrative Agent, each
         Participating Bank shall repay to the Administrative Agent forthwith on
         demand such amount distributed to such Participating Bank, together
         with interest thereon at the Federal Funds Rate for each day from the
         date such amount is distributed to such Participating Bank until the
         date such Participating Bank repays such amount to the Administrative
         Agent. A certificate of the Administrative Agent submitted to any
         Participating Bank with respect to any amounts owing by such
         Participating Bank under this paragraph (d) shall be conclusive and
         binding for all purposes absent manifest error.

SECTION 2.7       SECURITY INTEREST IN PLEDGED BONDS.

The Company hereby grants to the Administrative Agent, for the benefit of each
of the Banks, a first priority security interest in all of its right, title and
interest in and to all Pledged Bonds to secure the repayment of the Obligations.
This Agreement shall constitute a security agreement for purposes of the Uniform
Commercial Code. The Company hereby agrees from time to time, at the request of
the Administrative Agent, to cause any financing statements to be filed,
registered and recorded in such manner and in all places as may be required by
law or reasonably

                                      -13-
<PAGE>

requested by the Administrative Agent in order to fully perfect and protect any
lien and security interest created hereby and from time to time will perform or
cause to be performed any other act as provided by law and will execute or cause
to be executed any and all continuation statements and further instruments that
may be reasonably requested or required by the Administrative Agent for such
perfection and protection. The Administrative Agent hereby appoints the Trustee
as its bailee for purposes of perfecting its security interest in the Pledged
Bonds.

SECTION 2.8       FEES.

The Company will pay, or cause to be paid, to the Administrative Agent:

                  (a)      for the account of the Participating Banks in

         credit fee on the average daily Available Amount at a rate equal to the
         L/C Margin. Such fee shall be payable in arrears on the last day of
         each calendar quarter and on the Termination Date, unless the Letter of
         Credit is terminated in whole on any earlier date, in which event the
         letter of credit fee for the period to the date of such termination
         shall be paid on the date of such termination;

                  (b)      for the account of the Issuing Bank, on demand, all
         administrative fees charged by the Issuing Bank in the ordinary course
         of business in connection with the honoring of drafts under the Letter
         of Credit, amendments thereto, transfers thereof and all other activity
         with respect to the Letter of Credit at the then current rates
         published by the Bank for such services rendered on behalf of customers
         of the Issuing Bank generally; and

                  (c)      for the account of the Administrative Agent, on the
         date of each transfer of the Letter of Credit to a successor Trustee, a
         transfer fee in an amount equal to the Issuing Bank's then standard
         out-of-pocket fee for transfers in effect on such date.

SECTION 2.9       METHOD OF PAYMENT.

All payments to be made by the Company and the Participating Banks under this
Agreement shall be made to the Administrative Agent at Wells Fargo Bank,

Each Participating Bank may fund its Drawing Loans at such branch, office or

the Administrative Agent and the Company. Notwithstanding any other provision of
this Agreement, each Participating Bank shall be entitled to fund and maintain
its funding of all or any part of each Drawing Loan in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if in the first 180 days the Issuing
Bank had actually funded and maintained such Drawing Loan through the purchase
of deposits in the eurodollar interbank market having a maturity corresponding
to the Interest Periods applicable to such

                                      -14-
<PAGE>

Drawing Loan and bearing an interest rate equal to the applicable LIBOR for such
Interest Periods.

SECTION 2.11      COMPUTATION OF INTEREST.

All computations of interest and fees payable by the Company under this
Agreement shall be made on the basis of a 360-day year and actual days elapsed
except where interest is computed using the Base Rate, in which case a year of
365 or 366 days and actual days elapsed shall be used. Interest shall accrue
during each period during which interest is computed from and including the
first day thereof to but excluding the last day thereof.

SECTION 2.12      PAYMENT DUE ON NON-BUSINESS DAY TO BE MADE ON NEXT BUSINESS
DAY.

If any sum becomes payable pursuant to this Agreement on a day which is not a
Business Day, the date for payment thereof shall be extended, without penalty,
to the next succeeding Business Day, and such extended time shall be included in
the computation of interest and fees. If the date for any payment of principal
is extended by operation of law or otherwise, interest shall be payable for such
extended time.

                  (a)      No later than 90 days before each anniversary date of
         this Agreement the Company may make a request for a one-year extension
         of the Stated Expiration Date in a written notice to the Administrative
         Agent. The Administrative Agent will promptly inform the Issuing Bank
         and the Participating Banks of any such request. Each of the Issuing
         Bank and each Participating Bank may, in its sole and absolute
         discretion, determine whether to consent to such request. If each of
         the Issuing Bank and each Participating Bank shall give irrevocable
         written notice to the Administrative Agent not later than 45 days prior
         to such Stated Expiration Date stating that it is so willing to extend
         the Stated Expiration Date, then, subject to any conditions precedent
         that the Administrative Agent may require in connection with such
         extension (e.g., the remaking of representations and warranties, no
         Potential Default or Event of Default having occurred or the delivery
         of a legal opinion and other appropriate documentation), the Stated
         Expiration Date shall be so extended, such extension to be effective as
         provided in Section 2.15(b) and the Administrative Agent shall promptly
         notify the Issuing Bank, the Participating Banks and the Company of
         such circumstance. Failure by the Issuing Bank or any Participating
         Bank to deliver such a notice to the Administrative Agent within

                                      -15-
<PAGE>

         such time frame shall be deemed to be a denial of the Company's request
         by the Issuing Bank or such Participating Bank. If the Issuing Bank and
         each Participating Bank have not delivered written notices in
         accordance with the terms hereof consenting to the extension of the
         Stated Expiration Date, the Stated Expiration Date shall not be
         extended and the Administrative Agent shall promptly notify the Issuing
         Bank, the Participating Banks and the Company of such circumstance. Any
         date to which the Stated Expiration Date has been extended in
         accordance with this Section 2.15 may be extended in like manner.

                  (b)      If the Stated Expiration Date is extended pursuant to
         Section 2.15(a), the Issuing Bank shall deliver to the Trustee an
         amendment (an "Extension Amendment") designating the date to which the
         Stated Expiration Date is being extended. Such extension of the Stated
         Expiration Date shall be effective, after receipt of such notice, on
         the Business Day following the date of delivery of such Extension
         Amendment, and thereafter all references in this Agreement to the
         Stated Expiration Date shall be deemed to be references to the date
         designated as such in the most recent Extension Amendment delivered to
         the Trustee. No later than 90 days prior to the then current Stated
         Expiration Date the Company shall notify the Issuing Bank as to whether
         it will provide the Trustee with an Alternate Letter of Credit or no
         credit enhancement.

SECTION 2.16      PROVISIONS APPLICABLE TO LIBOR DRAWING LOANS.

                  (a)      FUNDING LOSSES. If the Company makes any payment or
         prepayment of principal with respect to any Drawing Loan in the first
         180 days on any day other than the last day of an Interest Period
         applicable to such Drawing Loan, the Company shall reimburse each
         Participating Bank, within 15 days after demand, for any resulting loss
         or expense incurred by it (or by any existing or prospective
         participant in the related Drawing Loan) including, without limitation,
         any loss incurred in obtaining, liquidating or employing deposits from
         third parties, but excluding loss of margin for the period after such
         payment or failure to borrow or prepay; PROVIDED, HOWEVER, that such
         Participating Bank shall have delivered to the Company a certificate as
         to the amount of such loss or expense, which certificate shall be
         conclusive in the absence of manifest error.

                  (b)      BASIS FOR DETERMINING INTEREST RATE UNAVAILABLE. If
         on or prior to the first day of any Interest Period deposits in dollars
         (in the applicable amounts) are not being offered to a Participating
         Bank in the London interbank market for such Interest Period, such
         Participating Bank shall forthwith give notice thereof to the
         Administrative Agent and the Company, whereupon the obligation of the
         Banks to make a Drawing Loan at LIBOR shall be suspended until that
         Participating Bank notifies the Company that the circumstances giving
         rise to such suspension no longer exist. Such Participating Bank shall
         instead make such Drawing Loan at the Base Rate for the first 365 days.

                  (c)      ILLEGALITY. If after the Date of Issuance the
         adoption of any applicable law, rule or regulation, 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, or
         compliance by any Participating Bank with any request or directive
         (whether or not having the force of law)

                                      -16-
<PAGE>

         of any such authority, central bank or comparable agency shall make it
         unlawful or impossible for any Participating Bank to make, maintain or
         fund its Drawing Loans at LIBOR, such Participating Bank shall
         forthwith so notify the Administrative Agent and the Company, whereupon
         such Participating Bank's obligation to fund any Drawing Loans at LIBOR
         shall be suspended. If any Participating Bank shall determine that it
         may not lawfully continue to maintain and fund any of its outstanding
         Drawing Loans bearing interest at LIBOR to maturity and shall so
         specify in such notice, the Company shall immediately prepay in full
         the then outstanding principal amount of each such Drawing Loan bearing
         interest at LIBOR, together with accrued interest thereon. Concurrently
         with prepaying each such Drawing Loan, the Company may borrow a Drawing
         Loan at the Base Rate in an equal principal amount for a period
         coincident with the remaining term of the Interest Period applicable to
         such Drawing Loan.

SECTION 2.17      RESCISSION OF PAYMENTS.

If, following the payment of any Reimbursement Obligation or any interest
thereon by the Company to the Administrative Agent pursuant to Section 2.6, any
portion of such Reimbursement Obligation and/or interest shall he rescinded or
must otherwise be restored by the Issuing Bank, then each Participating Bank,
upon notice to it by the Administrative Agent of such rescission or restoration,
shall pay to the Administrative Agent its Commitment Percentage of the amount so
rescinded or restored.

         business in each jurisdiction in which the character of the property
         owned or leased by it therein or the transaction of its business makes

         reasonably (either individually or in the aggregate) result in a
         Material Adverse Change.

                  (b)      The Company has full corporate power and authority to
         enter into, execute, deliver and carry out its obligations under this

         Commitments) does not exceed $1,690,000,000 and Company's equity ratio
         is within the range of 49.27 to 66.65 percent.

                  (c)      The officers of the Company who have executed this
         Agreement, who have requested the issuance of the Letter of Credit and

         creditors' rights generally and by equitable principles.

                  (e)      Except as disclosed in the Company's Annual Report on

         there are no actions, suits or arbitration proceedings pending or, to
         the knowledge of the Company, threatened against the Company, at law or
         in equity, before any Governmental Body which individually or in the

         affect the financial condition of the Company or materially impair the
         ability of the Company to perform its obligations under this Agreement,

         in the Company's Quarterly Reports on Form 10-Q for the quarter ended

         Company other than as indicated on said financial statements and since
         December 31, 2005, there has been no Material Adverse Change.

                  (i)      To the best knowledge of the Company, the Company is
         not in default with respect to any judgment, order, writ, injunction,
         decree or decision of any Governmental Body which default could
         reasonably constitute, cause or result in a Material Adverse Change.

         its important activities, in the business of extending credit for the
         purpose of purchasing or carrying any margin stock within the meaning
         of Regulation U. No part of the proceeds of the Bonds or any Drawing
         Loan will be used, directly or indirectly, by the Company for a purpose
         which violates any law, rule, or regulation of any Governmental Body,
         including, without limitation, the provisions of Regulation U or X of
         the Board of Governors of the Federal Reserve System, as amended.

                  (k)      No Potential Default or Event of Default has occurred
         and is continuing or would result from the obligations incurred by the
         Company hereunder or by the actions contemplated hereby.

                  (l)      The representations and warranties of the Company in
         the Related Documents to which it is a party are true and correct in
         every material respect, and the Company has furnished the
         Administrative Agent a true and correct copy of all the Related
         Documents as in effect on the date hereof.

                  (m)      In the ordinary course of its business, the Company
         conducts an ongoing review of the effect of Environmental Laws on the
         business, operations and properties of the Company and its
         Subsidiaries, in the course of which it identifies and evaluates
         liabilities and costs arising under or imposed by Environmental Laws
         (including, without limitation, any capital or operating expenditures
         required for clean-up or closure of properties presently or previously
         owned, any capital or operating expenditures required to achieve or
         maintain compliance with environmental protection standards imposed by
         Environmental Law, any related constraints on operating activities,
         including any periodic or permanent shutdown of any facility or
         reduction in the level of or change in the nature of operations
         conducted in such place, any costs or liabilities in connection with
         off-site disposal of wastes or Hazardous Substances, and any actual or
         potential liabilities to third parties, including employees). On the
         basis of this review, the Company has no reason to conclude that such
         liabilities and costs arising under, including the costs of compliance
         with, Environmental Laws, could reasonably constitute, cause or result
         in a Material Adverse Change.

                  (n)      No Plan has been terminated nor have any proceedings
         been instituted to terminate any Plan; the Company has not withdrawn
         from any Multiemployer Plan in a complete or partial withdrawal nor has
         a condition occurred which if continued would result in a complete or
         partial withdrawal; the Company has not incurred any withdrawal
         liability under Section 4201 or 4204 of ERISA with respect to any
         Multiemployer Plan; the Company has not incurred any liability to PBGC
         other than for required insurance premiums which have been paid when
         due; no Reportable Event with respect to any Plan has occurred; and no
         Plan has an accumulated funding deficiency under Section 302 of ERISA
         or Section 412 of the Code. Each employee benefit plan (as defined in
         Section 3(3) of ERISA) maintained by the Company is in compliance with
         ERISA, except where the failure so to comply could not reasonably
         constitute, cause or result in a Material Adverse Change.

Company to the Banks under this Agreement. Following expiration of the Letter of
Credit in accordance with its terms, and the payment of all amounts payable by
the Company to the Banks under this Agreement, any funds remaining in the
Special Deposit Account shall be returned by the Administrative Agent to the
Company or paid to whomever may be legally entitled thereto. The Administrative
Agent shall have full ownership and control of the Special Deposit Account, and,
except as set forth in the preceding sentence, the Company shall have no right
to withdraw the funds maintained in the Special Deposit Account.

                                  MISCELLANEOUS


SECTION 7.1       TAXES.

                  (a)      For the purposes of this Section 7.1, the following
         terms have the following meanings:

                  "TAXES" means any and all present or future taxes, duties,
                  levies, imposts, deductions, charges or withholdings with
                  respect to any payment by the Company pursuant to this
                  Agreement and all penalties and interest with respect thereto,
                  excluding (i) taxes imposed on its income, and franchise or
                  similar taxes imposed on it, by a jurisdiction under the laws
                  of which any Bank is organized or in which its principal
                  executive office is located, in which its applicable lending
                  office is located or in which it would be subject to tax due
                  to some connection other than that created by this Agreement
                  and (ii) any United States withholding tax imposed on such
                  payments but only to the extent that such Bank is subject to
                  United States withholding tax on the Date of Issuance.

                  "OTHER TAXES" means any present or future stamp or documentary
                  taxes and any other excise or property taxes, or similar
                  charges or levies and all penalties and interest with respect
                  thereto, which arise from the making of any payment pursuant
                  to this Agreement or from the execution or delivery of this
                  Agreement or the Letter of Credit.

                  (b)      Any and all payments by the Company to or for the
         account of any Bank hereunder shall be made without deduction for any
         Taxes or Other Taxes; PROVIDED that, if the Company shall be required
         by law to deduct any Taxes or Other Taxes from any such payments, (i)
         the sum payable shall be increased as necessary so that after making
         all required deductions (including deductions applicable to additional
         sums payable under this Section) the applicable Bank receives an amount
         equal to the sum it would have received had no such deductions been
         made, (ii) the Company shall make such deductions, (iii) the Company
         shall pay the full amount deducted to the relevant taxation authority
         or other authority in accordance with applicable law and (iv) the
         Company shall furnish to the Banks, the original or a certified copy of
         a receipt evidencing payment thereof.

                  (c)      The Company agrees to indemnify each Bank for the
         full amount of Taxes or Other Taxes (including, without limitation, any
         Taxes or Other Taxes on amounts payable under this Section) paid by
         such Bank. This indemnification shall be paid within 15 days after any
         Bank makes appropriate demand therefor.

                  (d)      On or prior to the date of its execution and delivery
         of this Agreement, and from time to time thereafter if requested in
         writing by the Company (but only so long as each Bank remains lawfully
         able to do so), each Bank shall provide the Company with Internal
         Revenue Service form 1001 or 4224, as appropriate, or any successor
         form prescribed by the Internal Revenue Service, certifying that such
         Bank is entitled to

                                      -30-
<PAGE>

         benefits under an income tax treaty to which the United States is a
         party which exempts such Bank from United States withholding tax or
         reduces the rate of withholding tax on payments of interest for the
         account of such Bank or certifying that the income receivable pursuant
         to this Agreement is effectively connected with the conduct of a trade
         or business in the United States.

                  (e)      For any period with respect to which any Bank has
         failed to provide the Company with the appropriate form pursuant to
         Section 7.1(d) (unless such failure is due to a change in treaty, law
         or regulation occurring subsequent to the date on which such form
         originally was required to be provided), such Bank shall not be
         entitled to indemnification under Section 7.1(b) or (c) with respect to
         Taxes imposed by the United States; PROVIDED that, if such Bank, which
         is otherwise exempt from or subject to a reduced rate of withholding
         tax, becomes subject to Taxes because of its failure to deliver a form
         required hereunder, the Company shall take such steps (at the expense
         of such Bank) as such Bank shall reasonably request to assist such Bank
         to recover such Taxes.

                  (f)      If the Company is required to pay additional amounts
         to or for the account of any Bank pursuant to this Section, then such
         Bank will change the jurisdiction of its applicable lending office if,
         in the judgment of such Bank, such change (i) will eliminate or reduce
         any such additional payment which may thereafter accrue and (ii) is not
         otherwise disadvantageous to such Bank in its sole judgment.

SECTION 7.2       INCREASED COSTS.

                  (a)      If after the Date of Issuance any change in any
         applicable law, treaty, regulation, guideline or directive (including,
         without limitation, regulations and guidelines with respect to capital
         adequacy and Regulation D promulgated by the Board of Governors of the
         Federal Reserve System as now and from time to time hereafter in
         effect) or any new law, treaty, regulation, guideline or directive, or
         any interpretation of any of the foregoing by any authority charged
         with the administration or interpretation thereof or any central bank
         of other fiscal, monetary or other authority having jurisdiction over
         any Bank or the transactions contemplated by this Agreement (whether or
         not having the force of law) (all of the foregoing being referred to as
         a "REGULATORY CHANGE") shall:

                           (i)     subject such Bank to any tax, deduction or
                  withholding with respect to the Bonds, the Letter of Credit or
                  this Agreement, or any amount paid or to be paid by such Bank
                  as the issuer of the Letter of Credit (other than any tax
                  measured by or based upon the overall net income of such Bank
                  imposed by any jurisdiction having control over such Bank);

                           (ii)    impose, modify, require, make or deem
                  applicable to any Bank, any reserve requirement (other than
                  reserves against "EUROCURRENCY LIABILITIES" under paragraph
                  (b) below), capital requirement, special deposit requirement,
                  insurance assessment or similar requirement against any assets
                  held by, deposits with or for the account of, or loans,
                  letters of credit or commitments by, an office of such Bank;

                                      -31-
<PAGE>

                           (iii)   change the basis of taxation of payments due
                  any Bank under this Agreement or the Bonds (other than by a
                  change in taxation of the overall net income of such Bank);

                           (iv)    cause or deem letters of credit to be assets
                  held by such Bank and/or as deposits on its books; or

                           (v)     impose upon such Bank any other condition
                  with respect to such amount paid or payable to or by such Bank
                  or with respect to this Agreement, the Letter of Credit or the
                  Bonds;

         and the result of any of the foregoing is to increase the cost to any
         Bank of making any payment or maintaining the Letter of Credit, or to
         reduce the amount of any payment (whether of principal, interest or
         otherwise) receivable by such Bank, or to reduce the rate of return on
         the capital of such Bank (taking into consideration such Bank's
         policies with respect to capital adequacy) or to require such Bank to
         make any payment on or calculated by reference to the gross amount of
         any sum received by it, or to increase the cost to such Bank of making
         or maintaining any Drawing Loan at LIBOR, or to reduce the amount of
         any sum received or receivable by such Bank under this Agreement with
         respect thereto, in each case by an amount which such Bank in its
         reasonable judgment deems material, then:

                              (A)   such Bank shall promptly notify the Company
                                    in writing of the happening of such event
                                    and will designate a different lending
                                    office if such designation will avoid the
                                    need for, or reduce the amount of such
                                    compensation and will not, in the judgment
                                    of such Bank, be otherwise disadvantageous
                                    to such Bank;

                              (B)   such Bank shall  promptly  deliver to the
                                    Company a certificate stating the change
                                    which has occurred or the reserve
                                    requirements or other costs or conditions
                                    which have been imposed on such Bank or the
                                    request, direction or requirement with which
                                    it has complied, together with the date
                                    thereof, the amount of such increased cost,
                                    reduction or payment and a reasonably
                                    detailed description of the way in which
                                    such amount has been calculated, and such
                                    Bank's determination of such amounts, absent
                                    fraud or manifest error, shall be conclusive
                                    (in determining such amount, such Bank may
                                    use any reasonable averaging and attribution
                                    methods); and


                              (C)   the Company shall pay to each Bank, from
                                    time to time as specified by such Bank, such
                                    amount as will compensate such Banks, for
                                    such additional cost, reduction or payment.

         The protection of this paragraph shall be available to each Bank
         regardless of any possible contention of invalidity or inapplicability
         of the law, regulation or condition which has been imposed; PROVIDED,
         HOWEVER, that if it shall later be determined by such

                                      -32-
<PAGE>

         Bank that any amount so paid by the Company pursuant to this Section
         7.2 is in excess of the amount payable under the provisions hereof,
         such Bank shall refund such excess amount to the Company.

                  (b)      Without limiting the effect of the foregoing, the
         Company shall pay to the Issuing Bank and each Participating Bank on
         the last day of each Interest Period so long as such Bank is
         maintaining reserves against "EUROCURRENCY LIABILITIES" under
         Regulation D (or so long as such Bank is, by reason of any Regulatory
         Change, maintaining reserves against any other category of liabilities
         that includes deposits by reference to which the interest rate on
         Drawing Loans bearing interest at LIBOR is determined as provided in
         this Agreement or against any category of extensions of credit or other
         assets of such Bank that includes any Drawing Loans bearing interest at
         LIBOR) an additional amount (determined by such Bank and notified to
         the Company) equal to the product of the following for each such
         Drawing Loan for each day during such Interest Period:

                           (i)     the principal amount of such Drawing Loan
                  outstanding on such day;

                           (ii)    the remainder of (x) a fraction the numerator
         of which is the rate (expressed as a decimal) at which interest accrues
         on such Drawing Loan for such Interest Period as provided in this
         Agreement and the denominator of which is one minus the effective rate
         (expressed as a decimal) at which such reserve requirements are imposed
         on such Bank on such day minus (y) such numerator; and

                           (iii)   1/360.

SECTION 7.3       RIGHT OF SETOFF; OTHER COLLATERAL.

                  (a)      In addition to any rights now or hereafter granted
         under applicable law and not by way of limitation of any such rights,
         upon the occurrence of any Event of Default, each Bank is hereby
         authorized by the Company at any time or from time to time, without
         notice to the Company or to any other Person, any such notice being
         hereby expressly waived, to set off and to appropriate and to apply any
         and all deposits (general or special, including, but not limited to,
         indebtedness evidenced by certificates of deposit, whether matured or
         unmatured, and in whatever currency denominated) and any other
         indebtedness at any time held or owing by such Bank or that subsequent
         holder to or for the credit or the account of the Company, whether or
         not matured, against and on account of the obligations and liabilities
         of the Company to such Bank or that subsequent holder hereunder,
         including, but not limited to, all claims of any nature or description
         arising out of or connected with this Agreement and the Related
         Documents, irrespective of whether or not (a) the Administrative Agent
         shall have made any demand hereunder or (b) the principal or the
         interest on the Drawing Loans and other amounts due hereunder shall
         have become due and payable and although said obligations and
         liabilities, or any of them, may be contingent or unmatured.

                                      -33-
<PAGE>

                  (b)      Each of the Issuing Bank and each Participating Bank
         agrees with each other party hereto that if such Bank shall receive and
         retain any payment, whether by set-off or application of deposit
         balances or otherwise, hereunder in excess of its ratable share of
         payments on all such obligations then outstanding to the Banks, then
         such Bank shall purchase for cash at face value, but without recourse,
         ratably from each of the other Banks such amount of the Obligations, or
         participations therein, held by each such other Banks (or interest
         therein) as shall be necessary to cause such Bank to share such excess
         payment ratably with all the other Banks; PROVIDED, HOWEVER, that if
         any such purchase is made by any Bank, and if such excess payment or
         part thereof is thereafter recovered from such purchasing Bank, the
         related purchases from the other Banks shall be rescinded ratably and
         the purchase price restored as to the portion of such excess payment so
         recovered, but without interest.

                  (c)      The rights of any Bank under this Section 7.3 are in
         addition to, in augmentation of, and, except as specifically provided
         in this Section 7.3, do not derogate from or impair other rights and
         remedies (including, without limitation, other rights of setoff) which
         such Bank may have.

SECTION 7.4       INDEMNITY; COSTS AND EXPENSES.

                  (a)      The Company hereby agrees to indemnify each Bank, its
         affiliates and the respective directors, officers, agents and employees
         of the foregoing (each an "INDEMNITEE") and hold each Indemnitee
         harmless from and against any and all liabilities, losses, damages,
         costs and expenses of any kind, including, without limitation, the
         reasonable fees and disbursements of counsel, which may be incurred by
         such Indemnitee in connection with any investigative, administrative or
         judicial proceeding (whether or not such Indemnitee shall be designated
         a party thereto) brought or threatened relating to this Agreement, the
         Letter of Credit, the Drawing Loans, any drawing under the Letter of
         Credit or any actual or proposed use of proceeds of the drawings under
         the Letter of Credit; except, only if, and to the extent that any such
         claim, damage, loss, liability, cost or expense shall be caused by the
         willful misconduct or gross negligence of such Indemnitee in performing
         or failing to perform its obligations under this Agreement or in making
         payment against a drawing presented under the Letter of Credit which
         does not comply with the terms thereof (it being understood and agreed
         by the parties hereto that in making such payment the Issuing Bank's
         exclusive reliance on the documents presented to the Issuing Bank in
         accordance with the terms of the Letter of Credit as to any and all
         matters set forth therein, whether or not any statement or any document
         presented pursuant to the Letter of Credit proves to be forged,
         fraudulent, invalid or insufficient in any respect or any statement
         therein proves to be untrue or inaccurate in any respect whatsoever
         shall not be deemed willful misconduct or gross negligence of the
         Issuing Bank).

                  (b)      The Company shall pay (i) all reasonable costs and
         out-of-pocket expenses of the Issuing Bank and the Administrative
         Agent, including, without limitation, costs in connection with the
         negotiation, documentation and execution of this Agreement and any and
         all documents, agreements and instruments related thereto, reasonable
         fees and disbursements of special counsel for the Issuing Bank and the
         Administrative Agent, in

                                      -34-
<PAGE>

         connection with any waiver or consent hereunder or any amendment hereof
         or any Potential Default or Event of Default hereunder and (ii) if an
         Event of Default occurs, all reasonable out-of-pocket expenses incurred
         by the Issuing Bank and the Administrative Agent, including (without
         duplication) the reasonable fees and disbursements of outside counsel
         and the allocated cost of inside counsel, in connection with such Event
         of Default and investigation, collection, bankruptcy, insolvency and
         other enforcement proceedings resulting therefrom.

                  (c)      The Company hereby agrees to indemnify, defend and
         hold each Indemnitee harmless from and against any and all liabilities,
         losses, damages, costs and expenses of any kind, including, without
         limitation, the reasonable fees and disbursements of counsel, which may
         be incurred by such Indemnitee including reasonable expenses of
         investigating a claim, arising out of or in any way connected with, or
         as a result of the following:

                           (i)     the issuance, offering and sale of the Bonds;

                           (ii)    any acquisition or attempted acquisition of
                  stock or assets of another Person or entity by the Company, or
                  the use of any of the proceeds of any transaction contemplated
                  hereunder by the Company for the making or furtherance of any
                  such acquisition or attempted acquisition;

                           (iii)   any breach or alleged breach by the Company
                  of, or any liability or alleged liability of the Company
                  under, any Environmental Laws, or any liability or alleged
                  liability incurred by any Indemnitee under any Environmental
                  Laws in connection with this Agreement, any Related Documents
                  or the transactions contemplated hereunder or thereunder;

                           (iv)    the negotiation, preparation, execution,
                  delivery, administration, and enforcement of this Agreement,
                  the Related Documents and any other document required
                  hereunder or thereunder, including, without limitation, any
                  amendment, supplement, modification or waiver of or to any of
                  the foregoing or the consummation or failure to consummate the
                  transactions contemplated hereby or thereby, or the

PROVIDED, HOWEVER, that such indemnity shall not apply to any such losses,
claims, damages, liabilities or related expenses arising from (A) any unexcused
breach by the Administrative Agent of its obligations under this Agreement or
(B) any commitment made by the Administrative Agent to a person other than the
Company which would be breached by the performance of the obligations under this
Agreement. Nothing in this subsection is intended to limit the payment and

         attorneys' fees and expenses, including the fees and expenses of
         in-house counsel, and including reasonable expenses of investigating a
         claim) incurred by an indemnified party arising out of in any way
         connected with, or as a result of:

                           (i)     the assertion that any materials used in
                  connection with the offering and sale of the Bonds (except for
                  the materials provided by the Administrative Agent for such
                  use) contain an alleged untrue statement of a material fact or
                  an alleged omission to state any material fact necessary to
                  make the statements therein, in light of the circumstances
                  under which they were made, not misleading; or

                           (ii)    the failure to register the Bonds under the
                  Securities Act of 1933, as amended, or to qualify the
                  Financing Agreement or the Indenture under the Trust Indenture
                  Act of 1939, as amended.

                  (e)      The foregoing agreements and indemnities shall remain
         operative and in full force and effect regardless of termination of
         this Agreement, the consummation of or failure to consummate either the
         transactions contemplated by this Agreement or any amendment,
         supplement, modification or waiver, the drawing of any draft and
         reimbursement of the Issuing Bank therefor, the invalidity or
         unenforceability of any term or provision of this Agreement, any
         Related Documents, or any other document required hereunder or
         thereunder, any investigation made by or on behalf of the
         Administrative Agent, or the Company or the content or accuracy of any
         representation or warranty made under this Agreement, any Related
         Documents or any other document required hereunder or thereunder.

SECTION 7.5       NON-CONTROLLED PERSONS,

The Issuing Bank does not control, either directly or indirectly through one or
more intermediaries, the Company. Nor does the Company control, either directly
or indirectly through one or more intermediaries, the Issuing Bank. The Issuing
Bank and the Company shall provide written notice to the Trustee, Remarketing
Agent and the Owners at least 30 days prior to the consummation of any
transaction that would result in the Company controlling or being controlled by
the Issuing Bank.

SECTION 7.6       OBLIGATIONS ABSOLUTE.

The obligations of the Company under this Agreement including, without
limitation, all fees to be paid hereunder, shall be absolute, unconditional and

SECTION 7.7       LIABILITY OF THE ISSUING BANK.

The Company assumes all risks of the acts or omissions of the Trustee, the
Remarketing Agent, any Paying Agent or any agent of the Trustee, the Remarketing
Agent or any Paying Agent and any transferee of the Letter of Credit with
respect to their use of the Letter of Credit. Neither the Issuing Bank nor any
of its officers or directors shall be liable or responsible for (a) the use of
the Letter of Credit or for any acts or omissions of the Trustee and any
transferee in connection therewith, (b) the validity or genuineness of
documents, or of any endorsement thereon, even if such documents should in fact
prove to be in any or all respects invalid, fraudulent or forged, (c) payment by
the Issuing Bank against presentation of documents which do not comply with the
terms of the Letter of Credit, including failure of any documents to bear any
reference or adequate reference to the Letter of Credit, or (d) any other
circumstances whatsoever in making or failing to make payment under the Letter
of Credit; PROVIDED, HOWEVER, that the Company shall have a claim against the
Issuing Bank, and the Issuing Bank shall be liable to the Company, to the extent
of any direct, as opposed to consequential, damages suffered by the Company
which the Company proves were caused by (i) the Issuing Bank's willful
misconduct or gross negligence in determining whether documents presented under
the Letter of Credit comply with the terms of the Letter of Credit or (ii) the
Issuing Bank's wrongful failure to make lawful payment under the Letter of
Credit after the presentation to the Issuing Bank by the Trustee or a successor
trustee under the Indenture of a draft and certificate strictly complying with
the terms and conditions of the Letter of Credit (it being understood that in
making such payment the Issuing Bank's exclusive reliance on the documents
presented to the Issuing Bank in accordance with the terms of the Letter of
Credit as to any and all matters set forth therein, whether or not any statement
or any document presented pursuant to the Letter of Credit proves to forged,
fraudulent, invalid or insufficient in any respect or any statement whatsoever,
shall not be deemed willful misconduct or gross negligence of the Issuing Bank).
The Issuing Bank is hereby expressly authorized and directed to honor any demand
for payment which is made under the Letter of Credit without regard to, and
without any duty on its part to inquire into the existence of, any disputes or
controversies between the Issuer, the Company, the Remarketing Agent, the
Trustee, any Paying Agent, or any other person or the respective rights, duties
or liabilities of any of them, or whether any facts or occurrences represented
in any of the documents presented under the Letter of Credit are true and
correct.

SECTION 7.8       PARTICIPANTS, ETC.

                  (a)      Each Participating Bank shall have the right at any
         time, with the written consent of the Company (which consent shall not
         be unreasonably withheld) and the Issuing Bank (which consent shall be
         granted in the sole discretion of the Issuing Bank), to assign all or
         any part of its L/C Commitment (including the corresponding portion of
         its Commitment Percentage) to one or more other Persons; PROVIDED that
         such assignment is in an amount of at least $5,000,000 or the entire
         L/C Commitment of such Participating Bank, and if such assignment is
         not for such Participating Bank's entire L/C Commitment then such
         Participating Bank's L/C Commitment after giving effect to such
         assignment shall not be less than $5,000,000. Each such assignment
         shall set forth the assignees address for notices to be given
         hereunder. Upon any such assignment, delivery to the Administrative
         Agent of an executed copy of such assignment agreement and the forms
         referred to in Section 7.1 hereof, if applicable, and the payment of a
         $3,500 recordation

                                      -37-
<PAGE>

         fee to the Administrative Agent, the assignee shall become a
         Participating Bank hereunder, and the Participating Bank granting such
         assignment shall have its L/C Commitment (including the corresponding
         portion of its Commitment Percentage), and its obligations and rights
         in connection therewith, reduced by the amount
         of such assignment.

                  (b)      Each Participating Bank shall have the right at its
         own cost to grant participations (to be evidenced by one or more
         agreements or certificates of participation) in the L/C Commitments,
         and its corresponding participation obligation in the Letter of Credit,
         held by such Participating Bank at any time; PROVIDED that (i) no such
         participation shall relieve any Participating Bank of any of its
         obligations under this Agreement, (ii) no such participant shall have
         any rights under this Agreement except as provided in this Section
         7.8(b), and (iii) neither the Issuing Bank nor the Administrative Agent
         shall have any obligation or responsibility to such participant. Any
         party to which such a participation has been granted shall have the
         benefits of Sections 7.1, 7.2, 7.3, 7.4 and 7.15, but shall not be
         entitled to receive any greater payment under such Sections than the
         Participating Bank granting such participation would have been entitled
         to receive in connection with the rights transferred. Any agreement
         pursuant to which any Participating Bank may grant such a participating
         interest shall provide that such Participating Bank shall retain the
         sole right and responsibility to enforce the obligations of the Company
         hereunder, including, without limitation, the right to approve any
         amendment, modification or waiver of any provision of this Agreement;
         PROVIDED that such participation agreement may provide that such
         Participating Bank will not agree to any modification, amendment or
         waiver of this Agreement that would (A) increase or extend any L/C
         Commitment of such Participating Bank if such increase or extension
         would also increase or extend the participant's obligations, (B)
         forgive any amount of or postpone the date for payment of any principal
         of or interest on any Obligation payable hereunder in which such
         participant has an interest or (C) reduce the stated rate at which
         interest or fees in which such participant has an interest accrue
         hereunder.

SECTION 7.9       SURVIVAL OF THIS AGREEMENT.

All covenants, agreements, representations and warranties made in this Agreement
shall survive the issuance by the Issuing Bank of the Letter of Credit and shall
continue in full force and effect so long as the Letter of Credit shall be
unexpired or any sums drawn or due hereunder shall be outstanding and unpaid,
regardless of any investigation made by any person. Wherever in this Agreement
the Issuing Bank is referred to, such reference shall be deemed to include the
successors and assigns of the Issuing Bank and all covenants, promises and
agreements by or on behalf of the Company which are contained in this Agreement
shall inure to the benefit of the successors and assigns of the Issuing Bank.
The rights and duties of the Company, however, may not he assigned or
transferred, except as specifically provided in this Agreement or with the prior
written consent of the Administrative Agent, and all obligations of the Company
hereunder shall continue in full force and effect notwithstanding any assignment
by the Company of any of its rights or obligations under any of the Bond
Documents or any entering into, or consent by the Company, to any supplement or
amendment to any of the Bond Documents.

SECTION 7.10      AMENDMENTS AND WAIVERS.

Neither this Agreement nor any other Financing Document, nor any terms hereof or
thereof may be amended, supplemented or modified except in accordance with the
provisions of this subsection. The Majority Participating Banks may, or, with,
but only with, the written consent of the Majority Participating Banks, the
Administrative Agent or the Issuing Bank, as applicable, may, from time to time,
(a) enter into with the Company written amendments, supplements or modifications
hereto and to the other Financing Documents for the purpose of adding any
provisions to this Agreement or the other Financing Documents or changing in any
manner the rights of the Participating Banks or of the Company hereunder or
thereunder or (b) waive, on such terms and conditions as the Majority
Participating Banks or the Administrative Agent, as the case may be, may specify
in such instrument, any of the requirements of an Event of Default and its
consequences; PROVIDED, HOWEVER, that no such waiver and no such amendment,
supplement or modification shall, without the consent of each Participating
Bank, (i) reduce the amount or extend the scheduled date of maturity of any
Obligation or any installment thereof, or reduce the stated rate of any interest
or fee payable hereunder or extend the scheduled date of any payment thereof or
increase the amount or extend the Stated Expiration Date, in each case without
the consent of each Participating Bank affected thereby, or (ii) amend, modify
or waive any provision of this subsection or reduce the percentage specified in
the definition of Majority Participating Banks, or consent to the assignment or
transfer by the Company of any of its rights and obligations under this
Agreement and the other Financing Documents, in each case without the written
consent of all the Participating Banks, or (iii) amend, modify or waive any
provision of Article VIII or any provision hereunder affecting the rights or
obligations of the Issuing Bank without the written consent of the
Administrative Agent or the Issuing Bank, respectively. Any such waiver and any
such amendment, supplement or modification shall apply equally to each of the
Participating Banks and shall be binding upon the Company, the Participating
Banks, the Issuing Bank and the Administrative Agent. In the case of any waiver,
the Company, the Participating Banks, the Issuing Bank and the Administrative
Agent shall be restored to their former positions and rights hereunder and under
the other Financing Documents, and any Potential Default or Event of Default
waived shall be deemed to be cured and not continuing; no such waiver shall
extend to any subsequent or other Potential Default or Event of Default or
impair any right consequent thereon.

SECTION 7.11      WAIVER OF RIGHTS BY THE BANKS.

No course of dealing or failure or delay on the part of any Bank in exercising
any right, power or privilege hereunder or under the Letter of Credit shall
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise, or the exercise of any other right or
privilege. The rights of the Banks under this Agreement and the Letter of Credit
are cumulative and not exclusive of any rights or remedies which the Banks would
otherwise have.

SECTION 7.12      SEVERABILITY.

In case any one or more of the provisions contained in this Agreement shall be
held or deemed to be invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby. The

                                      -39-
<PAGE>

parties shall endeavor in good faith negotiations to replace the invalid,
illegal or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

SECTION 7.13      GOVERNING LAW; SUBMISSION TO JURISDICTION.

This Agreement shall be governed by and construed in accordance with the laws of
the State of Minnesota. The Company hereby submits to the nonexclusive
jurisdiction of the United States District Court for the District of Minnesota
and of any State court sitting in Hennepin County, Minnesota for purposes of all
legal proceedings arising out of or relating to this Agreement or the
transactions contemplated hereby. The Company irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such proceeding brought in such a court and any claim
that any such proceeding brought in such a court has been brought in an
inconvenient forum.

                                  ARTICLE VIII
                            THE ADMINISTRATIVE AGENT


SECTION 8.1       APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

Each Participating Bank hereby appoints Wells Fargo Bank, National Association,
as the Administrative Agent under this Agreement and hereby authorizes the
Administrative Agent to take such action as Administrative Agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. The relationship between the Administrative Agent
and the Participating Bank is and shall be that of agent and principal only, and
nothing contained in this Agreement or the Letter of Credit shall be construed
to constitute the Administrative Agent as a trustee or fiduciary for any
Participating Bank or the Company.

SECTION 8.2       ADMINISTRATIVE AGENT AND ITS AFFILIATES.

The Administrative Agent shall have the same rights and powers under this
Agreement as any other Participating Bank and may exercise or refrain from
exercising the same as though it were not the Administrative Agent, and the
Administrative Agent and its affiliates may accept deposits from, lend money to,
and generally engage in any kind of business with the Company or any affiliate
of the Company as if it were not the Administrative Agent hereunder. The term
"PARTICIPATING BANK" as used herein, unless the context otherwise clearly
requires, includes the Administrative Agent in its individual capacity as a
Participating Bank.

SECTION 8.3       ACTION BY ADMINISTRATIVE AGENT.

If the Administrative Agent delivers to the Company a written notice of an Event
of Default hereunder, the Administrative Agent shall promptly give each of the
Participating Banks written notice thereof. The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action hereunder with respect to any Potential
Default or Event of Default. In no event, however, shall the Administrative
Agent be required to take any action in violation of applicable law or of this
Agreement, and the Administrative Agent shall in all cases be fully justified in
failing or refusing to act hereunder or under the Letter of Credit unless it
shall be first indemnified to its reasonable satisfaction by the Participating
Banks against any and all costs, expense, and liability which may be incurred by
it by reason of taking or continuing to take any such action. The Administrative
Agent shall be entitled to assume that no Potential Default or Event of Default
exists unless notified to the contrary by a Participating Bank or the Company.
In all cases in which this Agreement and the Letter of Credit do not require the
Administrative Agent to take certain actions, the Administrative Agent shall be
fully justified in using its discretion in failing to take or in taking any
action hereunder and thereunder.

SECTION 8.4       CONSULTATION WITH EXPERTS.

The Administrative Agent may consult with legal counsel, independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

SECTION 8.5       LIABILITY OF ADMINISTRATIVE AGENT; CREDIT DECISION.

Neither the Administrative Agent nor any of its directors, officers, agents, or
employees shall be liable for any action taken or not taken by it in connection
transactions contemplated by this Agreement (i) with the consent or at the
request of the Majority Participating Banks or (ii) in the absence of its own
gross negligence or willful misconduct. Neither the Administrative Agent nor any
of its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with this Agreement or the Letter of Credit;
(ii) the performance or observance of any of the covenants or agreements of the
Company or any other party contained herein or in the Letter of Credit; (iii)
the satisfaction of any condition specified in Section 3.1 or 3.2 hereof, except
receipt of items required to be delivered to the Administrative Agent; or (iv)
the validity, effectiveness, genuineness, enforceability, perfection, value,
worth or collectibility hereof or of any other documents or writing furnished in
connection herewith; and the Administrative Agent makes no representation of any
kind or character with respect to any such matter mentioned in this sentence.
The Administrative Agent may execute any of its duties under this Agreement or
the Letter of Credit by or through employees, agents, and attorneys-in-fact and
shall not be answerable to the Participating Banks, the Company, or any other
Person for the default or misconduct of any such agents or attorneys-in-fact
selected with reasonable care. The Administrative Agent shall not incur any
liability by acting in reliance upon any notice, consent, certificate, other
document or statement (whether written or oral) believed by it to he genuine or
to be sent by the proper party or parties. Each Participating Bank acknowledges
that it has independently and without reliance on the Administrative Agent or
any other Participating Bank, and based upon such information, investigations
and inquiries as it deems appropriate, made its own credit analysis and decision
to extend credit to the Company in the manner set forth herein. It shall be the
responsibility of each Participating Bank to keep itself informed as to the
creditworthiness of the Company and any other relevant Person, and the
Administrative Agent shall have no liability to any Participating Bank with
respect thereto.

SECTION 8.6       INDEMNITY.

The Participating Banks shall ratably, in accordance with their respective
Commitment Percentage, indemnify and hold the Administrative Agent, and its
directors, officers, employees, agents and representatives harmless from and
against any liabilities, losses, costs or expenses suffered or incurred by it
hereunder or in connection with the transactions contemplated hereby, regardless
of when asserted or arising, except to the extent they are promptly reimbursed
for the same by the Company and except to the extent that any event giving rise
to a claim was caused by the gross negligence or willful misconduct of the party
seeking to be indemnified. The obligations of the Participating Banks under this
Section 8.6 shall survive termination of this Agreement.

SECTION 8.7       RESIGNATION OF ADMINISTRATIVE AGENT AND SUCCESSOR
ADMINISTRATIVE AGENT.

The Administrative Agent may resign at any time by giving written notice thereof
to the Participating Banks and the Company. Upon any such resignation of the
Administrative Agent, the Majority Participating Banks shall have the right to
appoint a successor Administrative Agent with the consent of the Company. If no
successor Administrative Agent shall have been so

                                      -44-

<PAGE>

appointed by the Majority Participating Banks, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent's giving of
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Participating Banks, appoint a successor Administrative Agent, which shall
be any Participating Bank hereunder or any commercial bank organized under the
laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $200,000,000. Upon the acceptance of
its appointment as the Administrative Agent hereunder, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights and duties of the retiring or removed Administrative Agent hereunder, and
the retiring Administrative Agent shall be discharged from its duties and
obligations thereunder. After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of this Section 8.7 and all
protective provisions hereof shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent.
