by the Issuer, under an indenture or indentures other than the Indenture, of obligations to provide additional funds to refund all or any principal amount of the Bonds.

The Company agrees that upon the occurrence and continuation of an Event of Default under Section 8.01(c) of the Indenture, the Trustee may demand an immediate mandatory redemption of the G&R Notes. The Trustee, as holder of the G&R Notes, has waived notice of any such mandatory redemption.

If a Credit Facility consisting of a direct pay letter of credit is then in effect for a series of Bonds, any available funds held by the Trustee in the Credit Facility Account for such series in the Purchase Fund pursuant to Section 5.11 of the Indenture, shall be credited against the amount due on such date with respect to the Purchase Price of the Bonds pursuant to this Section.

The Company agrees that each of the Trustee and the Remarketing Agent, and its officers, agents, servants and employees, shall not be liable for, and agrees that it will at all times indemnify and hold harmless each of the Trustee and the Remarketing Agent, its officers, agents, servants and employees against, any and all losses, costs, charges, expenses, judgments and liabilities created by or arising out of this Agreement, the Indenture or the Tax Agreement, that may be occasioned by any cause (other than the negligence or willful misconduct of the Trustee or the Remarketing Agent, as the case may be, its officers, servants and employees as fully and finally determined by a court of competent jurisdiction). In case any action shall be brought against the Trustee or the Remarketing Agent in respect of which indemnity may be sought against the Company, the Trustee upon receiving written notice of such action or the Remarketing Agent, as the case may be, shall promptly notify the Company in writing and the Company shall be entitled to assume control of the defense thereof, including the employment of Counsel reasonably satisfactory to the Trustee and the payment of all expenses. The Trustee or the Remarketing Agent, as the case may be, shall have the right to employ separate Counsel in any such action and participate in the defense thereof, but the fees and expenses of such Counsel shall be paid by the Trustee or the Remarketing Agent, as the case may be, unless (i) the employment of such Counsel has been authorized by the Company, (ii) the Trustee or the Remarketing Agent, as the case may be, has determined in good faith that there may be a conflict of interest of such Counsel retained by the Company between the Company and the Trustee or the Remarketing Agent, as the case may be, in the conduct of such defense, (iii) the Company ceases or terminates the employment of such Counsel retained by the Company or (iv) such Counsel retained by the Company withdraws with respect to such defense. The Company shall not be liable for any settlement of any such action without its consent (which consent shall not be unreasonably withheld), but if any such action is settled with the consent of the Company or if there be final judgment for the plaintiff in any such action, the Company agrees to indemnify and hold harmless the Trustee or the Remarketing Agent, as the case may be, from and against any loss or liability by reason of such settlement or final judgment. The Company agrees that the indemnification provided herein shall survive the termination of this Agreement or the Indenture or the resignation or removal of the Trustee or the Remarketing Agent, as the case may be. For purposes of this Section 4.2(c), the Trustee and the Remarketing Agent are deemed third party beneficiaries of this Agreement.

(d)    The Company agrees to pay all costs incurred in connection with the issuance of the Bonds from sources other than Bond proceeds and the Issuer shall have no obligation with respect to such costs.

(e)    The Company agrees to indemnify and hold harmless the Issuer and any member, officer, official or employee of the Issuer against any and all losses, costs, charges, expenses, judgments and liabilities created by or arising out of this Agreement, the Indenture, any Remarketing Agreement, the Bond Purchase Agreement or the Tax Agreement or otherwise incurred in connection with the issuance of the Bonds. The Company agrees to pay the Issuer its Closing Fee in connection

with the issuance of the Bonds in the amount of $170,000. The Issuer may submit to the Company periodic statements, not more frequently than monthly, for its Administrative Expenses and the Company shall make payment to the Issuer of the full amount of each such statement within 30 days after the Company receives such statement.

(f)    The Company agrees to pay to any Remarketing Agent for a series of Bonds the reasonable fees, charges and expenses of such Remarketing Agent when the same become due and the Issuer shall have no obligation or liability with respect to the payment of any such fees, charges or expenses. For purposes of this Section 4.2(f), the Remarketing Agent is deemed a third party beneficiary of this Agreement.

(g)    In the event the Company shall fail to make any of the payments required by (a) or (b) of this Section 4.2, the payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid and the Company will pay interest to the extent permitted by law, on any overdue amount at the rate of interest borne by the Bonds on the date on which such amount became due and payable until paid. In the event the Company shall fail to make any of the payments required by (c), (d), (e) or (f) of this Section 4.2, the payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid, and the Company agrees to to make any payment required by (e) of this Section 4.2 with interest thereon to the extent permitted by law at a rate 1% above the rate of interest then charged by the Trustee on 90-day commercial loans to its prime commercial borrowers until paid. The provisions of this Section shall survive the termination of this Agreement.

Section 4.3. No Defense or Set-Off. The obligation of the Company to make the payments pursuant to this Agreement and the G&R Notes shall be absolute and unconditional without defense or set-off by reason of any default by the Issuer under this Agreement or under any other agreement between the Company and the Issuer or for any other reason, it being the intention of the parties that the payments required hereunder will be paid in full when due without any delay or diminution whatsoever.

Section 4.4. Payments Pledged and Assigned. It is understood and agreed that all payments required to be made by the Company pursuant to Section 4.2 hereof (except payments made to the Trustee or any Remarketing Agent pursuant to Section 4.2(c) hereof, to the Issuer pursuant to Section 4.2(e) hereof, to any Remarketing Agent pursuant to Section 4.2(f) hereof, and to any or all of the Issuer, the Trustee and any Remarketing Agent pursuant to Section 4.2(g) hereof) and certain rights of the Issuer hereunder are pledged and assigned by the Indenture. The Company consents to such pledge and assignment. The Issuer hereby directs the Company and the Company hereby agrees to pay or cause to be paid to the Trustee all said amounts except payments to be made to the Issuer pursuant to Sections 4.2(e) and (g) hereof and payments to be made to any Remarketing Agent pursuant to Sections 4.2(c), (f) and (g) hereof. The Project will not constitute any part of the security for the Bonds, except to the extent that the Trustee as the holder of the G&R Notes has a lien on the Gas Facilities under the G&R Indenture.

Section 4.5. Payment of the Bonds and Other Amounts. The Bonds and interest and premium, if any, thereon shall be payable solely from (i) Repayment Installments made by the Company to the Trustee under Section 4.2(a) hereof and (ii) other moneys on deposit in the Bond Fund and available therefor.

Payments of principal of, and premium, if any, or interest on, the Bonds with moneys in the Bond Fund on any due date for a Repayment Installment required by Section 4.2(a) hereof shall be credited against the obligation to pay such Repayment Installment to the extent such moneys are available for such purpose.

Whenever any Bonds are redeemable in whole or in part at the option of the Company, the Trustee, on behalf of the Issuer, shall redeem the same upon the request of the Company and such redemption (unless conditional) shall be made from Repayment Installments made by the Company to the Trustee under Section 4.2(a) hereof equal to the redemption price of such Bonds.

Whenever payment or provision therefor has been made in respect of the principal of, or premium, if any, or interest on, all or any portion of the Bonds in accordance with the Indenture (whether at maturity or upon redemption or acceleration or upon provision for payment in accordance with Article XI of the Indenture), Repayment Installments shall be deemed paid to the extent such payment or provision therefor has been made and is considered to be a payment of principal of, or premium, if any, or interest on, such Bonds. If such Bonds are thereby deemed paid in full, the Trustee shall notify the Company and the Issuer that such payment requirement has been satisfied. Subject to the foregoing, or unless the Company is entitled to a credit under this Agreement or the Indenture, all payments shall be in the full amount required by Section 4.2(a) hereof.

Section 4.6. Credit Facility. (a)  No Credit Facility is being delivered for the Series A Bonds, the Series B Bonds, the Series F Bonds or the Series G Bonds on the Issue Date. The Company may at any time provide a Credit Facility with respect to the Bonds of a series (and substitute Credit Facilities therefor) in accordance with the conditions and provisions of this Section and of Section 6.17 of the Indenture and upon delivery to the Trustee of the items specified in subsection (c) below.

(b)    Any such Credit Facility for a series of Bonds shall meet the following conditions:

(i)    the provisions of such Credit Facility shall be reasonably acceptable to the Trustee;

(ii)    the effective date of such Credit Facility shall be a day that allows the Trustee to provide, if applicable, the required notice of mandatory purchase to the Owners of the Bonds pursuant to Section 5.05 of the Indenture and (A) any Business Day during a Daily Mode or a Weekly Mode, (B) a Mandatory Purchase Date described in Section 5.02, 5.03, 5.04 or 5.05 of the Indenture, or (C) any Business Day during which the Bonds of such series are permitted to be redeemed at the option of the Company pursuant to Section 4.01(a), (b), (c) or (d) of the Indenture and, if a Credit Facility is then in effect for such series of Bonds, on or before the last

Business Day that is two Business Days prior to the Expiration Date of such then existing Credit Facility;

(iii)    the term of such Credit Facility must extend at least 364 days or to at least the first date on which a replacement Credit Facility could become effective as described in clause (ii) above, whichever is longer; and

(iv)    if such Credit Facility is a direct pay letter of credit, it shall be in the amount of (A) the aggregate principal amount of the Bonds of such series to enable the Trustee to pay (1) the principal of such Bonds at maturity, upon call for redemption prior to maturity or acceleration, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee or the related Remarketing Agent for optional or mandatory purchase pursuant to Article V of the Indenture equal to the aggregate principal amount thereof to the extent remarketing proceeds are not available for such purpose in the related series subaccount of the Remarketing Proceeds Account and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to that portion of the redemption price of such Bonds equal to the principal that would have been payable on such Bonds on the redemption date had such Bonds been redeemed rather than purchased; plus (B) interest to accrue on the Bonds of such series during the term of such Credit Facility (which may be specified for a maximum Interest Accrual Period plus a certain number of days required by each Rating Agency then rating such Bonds to obtain a rating on such Bonds based on such letter of credit, and at a rate up to the Maximum Rate) to enable the Trustee to pay (1) the interest on the Bonds of such series when due, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee or the related Remarketing Agent for optional or mandatory purchase pursuant to Article V of the Indenture equal to the accrued and unpaid interest, if any, on such Bonds to the extent remarketing proceeds are not available for such purpose in the related series subaccount of the Remarketing Proceeds Account and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to that portion of the redemption price of such Bonds equal to the accrued and unpaid interest, if any, that would have been payable on such Bonds on the redemption date had such Bonds been redeemed rather than purchased; plus (C) any redemption premium that may be payable on the Bonds of such series during the term of such Credit Facility in the event of an optional redemption of all of the Bonds of such series to enable the Trustee to pay (1) any such redemption premium upon an optional redemption of such Bonds, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee for mandatory purchase pursuant to Article V of the Indenture equal to the premium that would have been payable on the redemption date had such Bonds been redeemed rather than purchased and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to the premium that would have been payable on the redemption date had the Bonds been redeemed rather than purchased. Notwithstanding the above, any redemption premium that may be payable on the Bonds of a series during the term of a Credit Facility (either as such premium or as a part of the Purchase Price thereof) need not be covered by such Credit Facility so long as it shall be paid with Eligible Moneys on the date, if any, it becomes due and payable

and if such coverage is not required by each Rating Agency then rating such Bonds to obtain a rating on such Bonds based on such letter of credit.

(c)    On or prior to the date, if any, of the delivery of a Credit Facility for a series of Bonds to the Trustee pursuant to subsection (a) above that meets the requirements set forth in subsection (b) above, the Company shall cause to be delivered to the Trustee and the Issuer a Favorable Opinion of Bond Counsel addressed to the Trustee and the Issuer. Upon receipt by the Trustee of any such Credit Facility and the opinion described above, the Trustee shall accept such Credit Facility and surrender any previously held Credit Facility to the Credit Provider thereof for cancellation promptly upon such replacement Credit Facility becoming effective; provided that the previous Credit Provider has honored all demands for payment on any Credit Facility being replaced.

(d)    As provided in Section 6.17(e) of the Indenture, the Trustee shall not sell, assign or otherwise transfer any Credit Facility, except to a successor Trustee under the Indenture and in accordance with the terms of the Credit Facility and the Indenture.

(e)    So long as a Credit Facility constituting a direct pay letter of credit is in effect for a series of Bonds, the Company agrees not to purchase, and not to permit any Affiliate of the Company or any other Person obligated (as guarantor or otherwise) to make payments on the Bonds or under the Agreement or the related Credit Agreement to purchase, the Bonds.

Section 5.1. Company to Maintain its Corporate Existence; Conditions Under Which Exceptions Permitted. The Company agrees that during the term of this Agreement it will maintain its existence as a corporation, will continue to maintain its status as a corporation in good standing in the State, will not dissolve or otherwise dispose of all or substantially all of its assets and will not combine or consolidate with or merge into another Person or permit one or more Persons to consolidate with or merge into it; provided, however, that the Company may so combine, consolidate with, or merge into another Person legally existing under the laws of one of the states of the United States, or permit one or more Persons to consolidate with or merge into it, or sell or otherwise transfer to another Person all or substantially all of its assets as an entirety and thereafter dissolve if the surviving, resulting, or transferee Person, as the case may be, assumes and agrees in writing to pay and perform all of the obligations of the Company hereunder. Any transfer of all or substantially all of the Company's generation assets shall not be deemed to constitute a "disposition of all or substantially all of the Company's assets" within the meaning of the preceding paragraph. Any such transfer of the Company's generation assets shall not relieve the Company of any of its obligations under this Agreement.

The Company need not comply with any of the provisions of this Section 5.1 if, at the time of such merger or consolidation, the Bonds will be defeased as provided in Article XI of the Indenture.

Section 5.2. Annual Statement The Company agrees to have an annual audit made by its regular independent certified public accountants and to furnish the Trustee (within 30 days after receipt by the Company) with a balance sheet and statement of income and surplus showing the financial condition of the Company and its consolidated subsidiaries, if any, at the close of each fiscal year and the results of operations of the Company and its consolidated subsidiaries, if any, for each fiscal year, accompanied by a report of said accountants that such statements have been prepared in accordance with generally accepted accounting principles. The Company's obligations under this Section 5.2 may be satisfied by delivering a copy of the Company's Annual Report on Form 10‑K to the Trustee within 10 days after it is filed with the Securities and Exchange Commission.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on officer's certificates).

Section 5.3. Maintenance and Repair; Insurance; Taxes; Disposition. Because the Company sold the Water Facilities that constitute a portion of the "Project" to the Truckee Meadows Water Authority in June of 2001 and does not operate or control the Water Facilities, the Company has no obligation to operate, maintain, repair or insure the Water Facilities. For so long as the Company shall own, operate or control the Gas Facilities (or portion thereof), to the extent permitted by applicable law and regulation, (i) the Company shall maintain or cause to be maintained the Gas Facilities (or portion thereof) during the term of this Agreement in good repair and keep them properly insured and shall promptly pay or cause to be paid all costs thereof, and (ii) the Company shall promptly pay or cause to be paid all installments of taxes, installments of special assessments, and all governmental, utility and other charges with respect to the Gas Facilities (or portion thereof), when due.

The Company may, at its own expense and in its own name in good faith contest or appeal any such taxes, assessments or other charges, or installments thereof, but shall not permit any such taxes, assessments or other charges, or installments thereof, to remain unpaid if such nonpayment shall subject the Gas Facilities or any part thereof to loss or forfeiture. The Company, subject to the provisions of Section 3.4 hereof, is not required by this Agreement to operate, or cause to be operated, any portion of the Gas Facilities owned by the Company after the Company shall deem in its discretion that such continued operation by the Company is not advisable, and in such event the Company may sell, lease or retire all or any such portion of the Gas Facilities. Subject to the provisions of Section 3.4 hereof, the net proceeds from such sale, lease or other disposition, if any, shall belong to, and may be used for any lawful purpose by, the Company. Upon disposition of the Gas Facilities in their entirety by the Company in accordance with this Section, the Company shall be discharged from its obligations to operate, maintain, repair and insure the Gas Facilities as set forth in this Section. Any such sale, lease or other disposition shall comply with the requirements

of the Tax Agreement. Under any and all circumstances, the Issuer shall have no obligation whatsoever with respect to the operation, maintenance, repair or insurance of the Project.

Section 5.4. Recordation and Other Instruments. The Company shall cause such security agreements, financing statements and all supplements thereto and other instruments as may be required from time to time to be kept, to be recorded and filed in such manner and in such places as may be required by law in order to fully preserve, protect and perfect the security of the Owners of the Bonds and the rights of the Trustee, and to perfect the security interest created by the Indenture.

Section 5.5. No Warranty by the Issuer. The Issuer makes no warranty, either express or implied, as to the Project or that it was or will be suitable for the purposes of the Company or needs of the Company.

Section 5.6. Agreement as to Ownership of the Project The Issuer and the Company agree that title to the Project shall not be in the Issuer, and that the Issuer shall have no interest in the Project.

Section 5.7. Company to Furnish Notice of Mode Changes. The Company is hereby granted the option to designate from time to time changes in Modes (and to rescind such changes) in the manner and to the extent set forth in Section 2.07 of the Indenture. In the event the Company elects to exercise any such option, the Company agrees that it shall cause notices of proposed changes in Modes (or rescissions thereof) to be given to the Notice Parties in accordance with the provisions of Section 2.07 of the Indenture and to deliver any Opinions of Bond Counsel required under the Indenture in connection therewith.

Section 5.8. Information Reporting, Etc. The Issuer covenants and agrees that, upon the direction of the Company or Bond Counsel, it will mail or cause to be mailed to the Secretary of the Treasury (or his designee as prescribed by regulation, currently the Internal Revenue Service Center, Ogden, Utah) a statement setting forth the information required by Section 149(e) of the Code, which statement shall be in the form of the Information Return for Tax-Exempt Private Activity Bond Issues (Form 8038) of the Internal Revenue Service (or any successor form) and which shall be completed by the Company and Bond Counsel based in part upon information supplied by the Company and Bond Counsel.

Section 5.9. Limited Liability of Issuer. Any obligation or liability of the Issuer created by or arising out of this Agreement or otherwise incurred in connection with the issuance of the Bonds (including without limitation any liability created by or arising out of the representations, warranties or covenants set forth herein or otherwise) shall not impose a debt or pecuniary liability upon the Issuer or the State or any political subdivision thereof, or a charge upon the general credit or taxing powers of any of the foregoing, but shall be payable solely out of the Revenues or other

amounts payable by the Company to the Issuer hereunder or otherwise (including without limitation any amounts derived from indemnifications given by the Company).

Neither the issuance of the Bonds nor the delivery of this Agreement shall, directly or indirectly or contingently, obligate the Issuer or the State or any political subdivision thereof to levy any form of taxation therefor or to make any appropriation for their payment. Nothing in the Bonds or in the Indenture or this Agreement or the proceedings of the Issuer authorizing the Bonds or in the Act or in any other related document shall be construed to authorize the Issuer to create a debt of the Issuer or the State or any political subdivision thereof within the meaning of any constitutional or statutory provision of the State. The principal of, and premium, if any, and interest on, the Bonds shall be payable solely from the funds pledged for their payment in accordance with the Indenture and available therefor under this Agreement. Neither the State nor any political subdivision thereof shall in any event be liable for the payment of the principal of, premium, if any, or interest on, the Bonds or for the performance of any pledge, obligation or agreement of any kind whatsoever which may be undertaken by the Issuer. No breach of any such pledge, obligation or agreement may impose any pecuniary liability upon the Issuer or the State or any political subdivision thereof, or any charge upon the general credit or against the taxing power of the Issuer or the State or any political subdivision thereof.

Section 5.10. Inspection of Project. Because the Company sold the Water Facilities that constitute a portion of the "Project" to the Truckee Meadows Water Authority in June of 2001 and does not operate or control the Water Facilities, the Issuer understands that the Company cannot grant the Issuer or its duly authorized agents the right to enter upon the site of the Water Facilities (or portion thereof) to examine and inspect the Water Facilities. The Company agrees that during the term of this Agreement, to the extent the Company owns, operates or controls the Gas Facilities (or portion thereof), the Issuer and its duly authorized agents shall have the right at all reasonable times during normal business hours to enter upon the site of the Gas Facilities (or portion thereof) to examine and inspect the Gas Facilities; provided, however, that this right is subject to federal and State laws and regulations applicable to the site of the Gas Facilities; and provided further that the Company reserves the right to restrict access to the Gas Facilities in accordance with reasonably adopted procedures relating to safety and security. The rights of access hereby reserved to the Issuer may be exercised only upon giving reasonable notice and after such agent shall have executed release of liability and secrecy agreements if requested by the Company in the form then currently used by the Company, and nothing contained in this Section or in any other provision of this Agreement shall be construed to entitle the Issuer to any information or inspection involving the confidential know-how of the Company. The limitations contained in this Section do not affect any rights of inspection or other rights the Issuer has as a result of any law, ordinance, regulation, contract or other instrument.

Section 5.11. Indenture Covenants. The Company covenants to observe and perform all of the obligations imposed on it under the Indenture.

Section 6.1. Events of Default Defined. Any one of the following which occurs and continues shall constitute an "Event of Default" pursuant to this Agreement:

(a)    failure by the Company to pay or cause to be paid any Repayment Installment when due which failure results in an Event of Default under subparagraph (a) or (b) of Section 8.01 of the Indenture; or

(b)    failure by the Company to pay or cause to be paid the Purchase Price of a Bond when due which failure constitutes an Event of Default under subparagraph (c) of Section 8.01 of the Indenture; or

(c)    failure by the Company to observe and perform any covenant, condition or agreement on its part to be observed or performed in this Agreement, other than as referred to in (a) and (b) above, for a period of 90 days after written notice, specifying such failure and requesting that it be remedied, given to the Company by the Trustee or to the Company and the Trustee by the Issuer, unless the Issuer and the Trustee shall agree in writing to an extension of such time prior to its expiration; provided, however, if the failure stated in the notice cannot be corrected within the applicable period, the Issuer and the Trustee will not unreasonably withhold their consent to an extension of such time period if corrective action is instituted within the applicable period and diligently pursued until the failure is corrected; or

(d)    a proceeding or case shall be commenced, without the application or consent of the Company, in any court of competent jurisdiction seeking (i) liquidation, reorganization, dissolution, winding-up or composition or adjustment of debts, (ii) the appointment of a trustee, receiver, custodian, liquidator or the like of the Company or of all or any substantial part of its assets, or (iii) similar relief under any law relating to bankruptcy, insolvency, reorganization, winding-up or composition or adjustment of debts, and such proceeding or cause shall continue undismissed, or an order, judgment, or decree approving or ordering any of the foregoing shall be entered and shall continue in effect for a period of 90 days; or an order for relief against the Company shall be entered against the Company in an involuntary case under the Bankruptcy Code (as now or hereafter in effect) or other applicable law; or

(e)    the Company shall admit in writing its inability to pay its debts generally as they become due or shall file a petition in voluntary bankruptcy or shall make any general assignment for the benefit of its creditors, or shall consent to the appointment of a receiver or trustee of all or substantially all of its property, or shall commence a voluntary case under the Bankruptcy Code (as now or hereafter in effect), or shall file in any court of competent jurisdiction a petition seeking to take advantage of any other law relating to bankruptcy, insolvency, reorganization, winding-up or composition or adjustment of debts, or shall fail

to controvert in a timely or appropriate manner, or acquiesce in writing to, any petition filed against it in an involuntary case under such Bankruptcy Code or other applicable law; or

(f)    dissolution or liquidation of the Company; provided that the term "dissolution or liquidation of the Company" shall not be construed to include the cessation of the corporate existence of the Company resulting from a combination, consolidation or merger of the Company into or with another Person or a dissolution or liquidation of the Company following a transfer of all or substantially all of its assets as an entity, under the conditions permitting such actions contained in Section 5.1 hereof; or

(g)    an Event of Default under the Indenture.

The provisions of Section 6.1(c) are subject to the limitation that the Company shall not be deemed in default if and so long as such failure is the result of Force Majeure. The Company agrees, however, to use commercially reasonable efforts to remedy the cause or causes preventing the Company from carrying out its agreements; provided that the settlement of strikes, lockouts and other industrial disturbances shall be entirely within the discretion of the Company and the Company shall not be required to make settlement of strikes, lockouts and other industrial disturbances by acceding to the demands of the opposing party or parties when such course is in the sole judgment of the Company unfavorable to the Company.

Section 6.2. Remedies on Default. Whenever any Event of Default referred to in Section 6.1 hereof shall have happened and be continuing, the Trustee, as assignee of the Issuer:

(a)    shall, by notice in writing to the Company and each Credit Provider, declare the unpaid balance of the Repayment Installments payable under Section 4.2(a) hereof to be due and payable immediately, if concurrently with or prior to such notice the unpaid principal amount of the Bonds shall have been declared to be due and payable, and upon any such declaration the same (being an amount sufficient, together with other moneys available therefor in the Bond Fund, to pay the unpaid principal of, premium, if any, and interest accrued on, the Bonds) shall become and shall be immediately due and payable as liquidated damages;

(b)    may take whatever action at law or in equity as may appear necessary or desirable to collect the payments and other amounts then due and thereafter to become due hereunder or to enforce performance and observance of any obligation, agreement or covenant of the Company under this Agreement; and

(c)    if applicable, shall immediately draw upon any Credit Facility constituting a letter of credit or otherwise realize moneys under any Credit Facility, if permitted by its terms and required by the terms of the Indenture, and apply the amount so drawn or realized in accordance with the Indenture and may exercise any remedy available to it thereunder.

Any amounts collected pursuant to action taken under this Section 6.2 shall be paid into the Bond Fund (unless otherwise provided in this Agreement) and applied in accordance with the

provisions of the Indenture. No action taken pursuant to this Section 6.2 shall relieve the Company from the Company's obligations pursuant to Section 4.2 hereof.

No recourse shall be had for any claim based on this Agreement against any officer, director or stockholder, past, present or future, of the Company as such, either directly or through the Company, under any constitutional provision, statute or rule of law, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise.

Nothing herein contained shall be construed to prevent the Issuer from enforcing directly any of its rights under Sections 4.2(e), 4.2(g), 5.3 and 6.4 hereof.

The Company shall promptly notify the Issuer of any action taken by the Company under the grant of authority from the Issuer under Section 8.01 of the Indenture.

Section 6.3. No Remedy Exclusive. No remedy herein conferred upon or reserved to the Issuer or the Trustee is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement or now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right and power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Issuer or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than such notice as may be herein expressly required. Subject to the provisions of the Indenture and hereof, such rights and remedies as are given the Issuer hereunder shall also extend to the Trustee. The Owners of the Bonds, subject to the provisions of the Indenture, shall be entitled to the benefit of all covenants and agreements herein contained.

Section 6.4. Agreement to Pay Fees and Expenses of Counsel. In the event the Company should default under any of the provisions of this Agreement and the Issuer or the Trustee should employ Counsel or incur other expenses for the collection of the indebtedness hereunder or the enforcement of performance or observance of any obligation or agreement on the part of the Company herein contained, the Company agrees that it will on written demand therefor pay to the Trustee or the Issuer (or to the Counsel for either of such parties if directed by such party), the reasonable fees and expenses of such Counsel and such other expenses so incurred by or on behalf of the Issuer or the Trustee.

Section 6.5. No Additional Waiver Implied by One Waiver; Consents to Waivers. In the event any agreement contained in this Agreement should be breached by either party and thereafter waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder. No waiver shall be effective unless in writing and signed by the party making the waiver. The Issuer shall have no power to waive any

default hereunder by the Company without the consent of the Trustee to such waiver. The Trustee shall have the power to waive any default by the Company hereunder, except a default under Section 3.4, 4.2(e), 4.2(g), 5.3 or 6.4 hereof, in so far as it pertains to the Issuer, without the prior written concurrence of the Issuer. Notwithstanding the foregoing, if, after the acceleration of the maturity of the outstanding Bonds by the Trustee pursuant to Section 8.01 of the Indenture, (i) all arrears of principal of and interest on the outstanding Bonds and interest on overdue principal and (to the extent permitted by law) on overdue installments of interest at the rate of interest borne by the Bonds on the date on which such principal or interest became due and payable and the premium, if any, on all Bonds then Outstanding which have become due and payable otherwise than by acceleration, and all other sums payable under the Indenture, except the principal of and the interest on such Bonds which by such acceleration shall have become due and payable, shall have been paid, (ii) all other things shall have been performed in respect of which there was a default, (iii) there shall have been paid the reasonable fees and expenses of the Trustee and of the Owners of such Bonds, including reasonable attorneys' fees paid or incurred and (iv) such event of default under the Indenture shall be waived in accordance with Section 8.04 of the Indenture with the consequence that such acceleration under Section 8.01 of the Indenture is rescinded, then the Company's default hereunder shall be deemed to have been waived and its consequences rescinded and no further action or consent by the Trustee or the Issuer shall be required; provided that there has been furnished an Opinion of Bond Counsel to the effect that such waiver will not adversely affect the exemption from federal income taxes of interest on the Bonds.

Section 6.6. Rights of Credit Providers upon an Event of Default. Notwithstanding any other provision of this Article VI, while any Credit Facility is in effect for any series of Bonds and so long as such Credit Provider is not in default with respect to its obligations thereunder, the Trustee and the Issuer may not exercise any remedy described in Section 6.2 hereof without each such Credit Provider's prior written consent and no Event of Default hereunder shall be waived by the Trustee or the Issuer or the Bondholders to the extent they may otherwise be permitted to waive an Event of Default hereunder, without, in any case, the prior written consent of each such Credit Provider and, if applicable, rescission by each such Credit Provider of any notice of an event of default under the related Credit Agreement. No Event of Default can be waived, in any circumstance, unless the Trustee has received written notice from each applicable Credit Provider that its Credit Facility has been fully reinstated and is in full force and effect. While any Credit Facility is in effect for any series of Bonds and so long as such Credit Provider is not in default with respect to its obligations thereunder, such Credit Provider shall be entitled, but not obligated, to request that the Trustee exercise or to direct the Trustee in the exercise of all rights and remedies upon the occurrence of an Event of Default under the Indenture as provided in Section 8.11 thereof.

If a Credit Facility is in effect for any series of Bonds, and the Credit Provider wrongfully dishonors a demand for payment made in strict compliance with the terms of the related Credit

Facility, for so long as such demand for payment remains unpaid by the Credit Provider, fifty-one percent (51%) of the Bondholders of the series of Bonds enhanced by such Credit Facility shall have the right at any time, by an instrument or instruments in writing executed and delivered to the Trustee, to direct the method and place of conducting all proceedings to be taken in connection with the enforcement of the terms and conditions of the Credit Facility or any other proceedings hereunder; provided that such direction shall be in accordance with applicable law.

In the event the Company elects to provide for the redemption of Bonds as permitted by this Section, the Company shall notify and instruct the Trustee in accordance with Section 7.3 hereof to redeem all or any portion of the Bonds in advance of maturity.

(b)    If the Company fails to give notice of a prepayment required by Section 7.3(a) hereof, such notice may be given by the Issuer, by the Trustee or by any holder or holders of 10% or more in aggregate principal amount of the Bonds outstanding. The Issuer and the Trustee at the request of the Company or any such Bondholder shall forthwith take all steps necessary under the applicable provisions of the Indenture (except that the Issuer shall not be required to make payment of any money required for such redemption other than from Revenues) to effect redemption of all or part of the then Outstanding Bonds, as the case may be, on the earliest practicable date thereafter on which such redemption may be made under applicable provisions of the Indenture.

(c)    Notwithstanding anything to the contrary in this Agreement, each notice contemplated in this Section that is given with respect to an optional prepayment pursuant to Section 7.1 hereof may state as provided in Section 4.03(a) of the Indenture that it is subject to and conditional upon receipt by the Trustee on or prior to the proposed prepayment date of moneys in an amount sufficient to effect such prepayment and such notice shall be of no force and effect and the prepayment need not be made and the Repayment Installments will not become due and payable on the proposed prepayment date unless such moneys are so received on or prior to the proposed prepayment date.
